Abstract

A well cover assembly includes a monitoring device and a well cover. The well cover includes a first protrusion and a second protrusion. A through hole is defined on the well cover and surrounded by the second protrusion. The monitoring device can be installed on the well cover. The monitoring device includes a monitoring terminal and a fixing bracket. The fixing bracket includes a first bracket and a second bracket. One end of the first bracket is fixed to the monitoring terminal, and another end can protrude from the through hole. The second bracket is connected to the end of the first bracket protruding from the through hole, the second bracket can extend from the end of the first bracket toward an edge of the second protrusion and toward the first protrusion. The second bracket further can clamp with each of the second protrusion and the first protrusion.

First claim

What is claimed is:

1. A monitoring device configured to be installed on a well cover, the well cover comprising a first protrusion and a second protrusion protruding from a same surface of the well cover, a through hole being defined on the well cover and surrounded by the second protrusion; the monitoring device comprising:
a monitoring terminal; and
a fixing bracket connected to the monitoring terminal, the fixing bracket comprising:
a first bracket, one end of the first bracket fixed to the monitoring terminal, and another end of the first bracket configured to protrude from the through hole; and
a second bracket connected to the end of the first bracket protruding from the through hole, the second bracket configured to extend from the end of the first bracket toward an edge of the second protrusion and toward the first protrusion, the second bracket further configured to clamp with each of the second protrusion and the first protrusion.

2. The monitoring device of claim 1 , wherein the first bracket comprises a first connecting plate and a second connecting plate, the second connecting plate extends along a first direction and connects the second bracket, the first connecting plate extends along a second direction and connects to the second connecting plate, and the second direction is perpendicular to the first direction.

3. The monitoring device of claim 2 , wherein the second bracket comprises a first clamping portion, a second clamping portion, and a connecting portion; the connecting portion is connected to one end of the second connecting plate away from the first connecting plate, both the first clamping portion and the second clamping portion are connected to the connecting portion away from the second connecting plate, the first clamping portion and the second clamping portion are spaced from each other along a third direction and configured to clamp with the first protrusion, both the first clamping portion and the second clamping portion are further configured to clamp with the second protrusion, and the third direction is perpendicular to the first direction and the second direction.

4. The monitoring device of claim 3 , wherein a length of the second connecting plate along the first direction is greater than a length of the first clamping portion or a length of the second clamping portion along the first direction.

5. The monitoring device of claim 3 , wherein a width of the second connecting plate along the third direction is less than or equal to a width of the through hole along the third direction.

6. The monitoring device of claim 1 , further comprising a connecting rod, wherein the connecting rod is fixed to the monitoring terminal; an external thread is defined on the connecting rod; a connecting hole is defined on the first bracket, an internal thread engaged with the external thread is defined on the connecting hole, the connecting rod is connected to the connecting hole through the internal thread and the external thread, and an end of the connecting rod away from the monitoring terminal is configured to be in contact with the well cover.

7. The monitoring device of claim 6 , wherein the monitoring terminal comprises a housing, the connecting rod connects the first bracket and the housing, a third protrusion is disposed at an end of the connecting rod, and the housing covers the third protrusion.

8. The monitoring device of claim 7 , wherein a thickness of the housing covering the third protrusion is at least 2 mm.

9. The monitoring device of claim 6 , further comprises an adhesive layer disposed between the connecting hole and the connecting rod.

10. A well cover assembly, comprising:
a well cover comprising a first protrusion and a second protrusion protruding from a same surface of the well cover, a through hole being defined on the well cover and surrounded by the second protrusion; and
a monitoring device configured to be installed on the well cover, the monitoring device comprising:
a monitoring terminal;
a fixing bracket connected to the monitoring terminal, the fixing bracket comprising:
a first bracket, one end of the first bracket fixed to the monitoring terminal, and another end of the first bracket configured to protrude from the through hole; and
a second bracket connected to the end of the first bracket protruding from the through hole, the second bracket configured to extend from the end of the first bracket toward an edge of the second protrusion and toward the first protrusion, the second bracket further configured to clamp with each of the second protrusion and the first protrusion.

11. The well cover assembly of claim 10 , wherein the first bracket comprises a first connecting plate and a second connecting plate, the second connecting plate extends along a first direction and connects the second bracket, the first connecting plate extends along a second direction and connects to the second connecting plate, and the second direction is perpendicular to the first direction.

12. The well cover assembly of claim 11 , wherein the second bracket comprises a first clamping portion, a second clamping portion, and a connecting portion; the connecting portion is connected to one end of the second connecting plate away from the first connecting plate, both the first clamping portion and the second clamping portion are connected to the connecting portion away from the second connecting plate, the first clamping portion and the second clamping portion are spaced from each other along a third direction and configured to clamp with the first protrusion, both the first clamping portion and the second clamping portion are further configured to clamp with the second protrusion, and the third direction is perpendicular to the first direction and the second direction.

13. The well cover assembly of claim 12 , wherein a length of the second connecting plate along the first direction is greater than a length of the first clamping portion or a length of the second clamping portion along the first direction.

14. The well cover assembly of claim 12 , wherein a width of the second connecting plate along the third direction is less than or equal to a width of the through hole along the third direction.

15. The well cover assembly of claim 10 , further comprising a connecting rod, wherein the connecting rod is fixed to the monitoring terminal; an external thread is defined on the connecting rod; a connecting hole is defined on the first bracket, an internal thread engaged with the external thread is defined on the connecting hole, the connecting rod is connected to the connecting hole through the internal thread and the external thread, and an end of the connecting rod away from the monitoring terminal is configured to be in contact with the well cover.
