Abstract

A well curb device and a method for controlling the same. The well curb device includes: a well curb, a well cover sensor, a light sensing component and an audible alertor. The well curb includes a placing portion for placing a well cover. The well cover sensor is disposed on the well curb, and is configured to detect whether a well cover is placed in the placing portion. The light sensing component is configured to trigger the audible alertor to issue an audio alarm of a specified decibel, when detecting that the light intensity around the well curb is greater than the specified value, thereby improving the safety of the well curb device.

First claim

What is claimed is:

1. A well curb device, comprising: a well curb, a well cover sensor, a light sensing component and an audible alertor, wherein the well cover sensor, the light sensing component and the audible alertor are sequentially connected,
the well curb comprises a placing portion for placing a well cover;
the well cover sensor is disposed on the well curb, and is configured to detect whether the well cover is placed in the placing portion;
the well cover sensor is configured to trigger the light sensing component to detect whether a light intensity around the well curb is greater than a specified value, when detecting that the well cover is not placed in the placing portion; and
the light sensing component is configured to trigger the audible alertor to issue an audio alarm of a specified decibel, when detecting that the light intensity around the well curb is greater than the specified value.

2. The well curb device according to claim 1 , further comprising a reminder component disposed in the well curb,
wherein the well cover sensor is configured to trigger the reminder component to send reminder information to a specified device in a wired or wireless manner, when detecting that the well cover is not placed in the placing portion.

3. The well curb device according to claim 1 , further comprising an energy source component connected with all of the well cover sensor, the light sensing component and the audible alertor.

4. The well curb device according to claim 1 , further comprising: a light alertor connected with the light sensing component,
wherein the light sensing component is configured to trigger the light alertor to issue a light alarm of a specified brightness, when detecting that the light intensity around the well cover is not greater than the specified value.

5. The well curb device according to claim 4 , wherein the specified brightness is positively correlated with the light intensity around the well cover.

6. The well curb device according to claim 4 , wherein the light sensing component is configured to trigger the audible alertor to issue an audio alarm, when detecting that the light intensity around the well cover is not greater than the specified value.

7. The well curb device according to claim 4 , further comprising: a liquid level sensing component connected with the light alertor and the audible alertor,
wherein the liquid level sensing component is configured to detect whether a water level around the well curb is higher than a specified height; and
the liquid level sensing component is configured to trigger the light alertor to issue a light alarm of a specified high brightness, and trigger the audible alertor to issue an audio alarm of a specified high decibel, when the water level around the well curb is higher than the specified height; the specified high brightness is greater than the specified brightness, and the specified high decibel is greater than the specified decibel.

8. The well curb device according to claim 7 , wherein the liquid level sensing component comprises: a liquid level sensor and a comparator,
the liquid level sensor is configured to acquire a height of water submerging the well curb device; and
the comparator is configured to compare the height with the specified height, and determine that the water level around the well curb is higher than the specified height, when the height is higher than the specified height.

9. The well curb device according to claim 4 , further comprising a guard component disposed in the well curb,
wherein the well cover sensor triggers the guard component to form a blocking structure in a space enclosed by the well curb, when detecting that the well covert is not placed in the placing portion, so as to block an object from passing through the well curb.

10. The well curb device according to claim 9 , further comprising a reset button connected with all of the well cover sensor, the light sensing component, the audible alertor, the light alertor and the guard component,
wherein the reset button is configured to control ON/OFF of the well cover sensor, the light sensing component, the audible alertor, the light alertor and the guard component.

11. The well curb device according to claim 9 , wherein the guard component comprises an expansible fence.

12. The well curb device according to claim 1 , wherein the well cover sensor comprises a pressure sensor.

13. The well curb device according to claim 12 , wherein the well cover sensor further comprises a comparator,
the pressure sensor is configured to acquire a pressure value applied to the placing portion; and
the comparator is configured to compare the pressure value with a specified pressure value, and determine that the well cover is not placed in the placing portion when the pressure value is less than the specified pressure value.

14. The well curb device according to claim 1 , further comprising a human body sensor connected with both the light sensing component and the audible alertor, wherein the human body sensor is configured to detect whether a human body is close to the well curb within a specified range of the well curb,
the light sensing component is configured to trigger the human body sensor to detect whether a human body is close to the well curb within the specified range, when detecting that the light intensity around the well curb is greater than the specified value; and
the human body sensor is configured to trigger the audible alertor to issue an audio alarm of the specified decibel, when detecting that a human body is close to the well curb within the specified range.

15. The well curb device according to claim 14 , wherein the human body sensor is an infrared sensor.

16. A control method for controlling the well curb device which comprises: a well curb, a well cover sensor, a light sensing component and an audible alertor, the well cover sensor, the light sensing component and the audible alertor being sequentially connected, the well curb comprising a placing portion for placing a well cover, and the well cover sensor being disposed on the well curb, comprising the steps of:
detecting, by the well cover sensor, whether a well cover is placed in the placing portion;
detecting, by the light sensing component, whether the light intensity around the well curb is greater than a specified value, when the well cover is not placed in the placing portion; and
issuing, by the audible alertor, an audio alarm of a specified decibel, when the light intensity around the well curb is greater than the specified value.

17. The method according to claim 16 , wherein the well curb device further comprises a guard component disposed in the well curb, and the method further comprises the step of:
triggering, by the well cover sensor, the guard component to form a blocking structure in a space enclosed by the well curb, when detecting that the well cover is not placed in the placing portion, so as to block an object from passing through the well curb.

18. The method according to claim 16 , wherein the well curb device further comprises a light alertor connected with the light sensing component, and the method further comprises the step of:
triggering, by the light sensor, the light alertor to issue a light alarm of a specified brightness, when detecting that the light intensity around the well cover is not greater than the specified value.
