Abstract

An automatic moving snow removal device including a moving module, driving a snow blower to move; a working module, including a working motor and a snow throwing mechanism driven by the working motor, the snow throwing mechanism is driven by the working motor to collect accumulated snow and inclusions on the ground and throw out of the snow throwing mechanism; and a control module, configured to control a rotary speed of the working motor to cause a speed when the inclusions depart from the snow throwing mechanism is not higher than 41 m/s.

First claim

What is claimed is:

1 . An automatic moving snow removal device comprising:
a working module, configured to execute specific work of the automatic moving snow removal device; a moving module, configured to drive the automatic moving snow removal device to move on the ground; an energy module, configured to provide energy for the moving module and the working module of the automatic moving snow removal device; a control module, wherein the control module is configured to control the working module and the moving module of the automatic moving snow removal device, such that the automatic moving snow removal device moves and works within a preset border; the automatic moving snow removal device further comprises a location navigation module, and the control module generates a snow removal path according to a map of the preset border, and controls the automatic moving snow removal device to move along the snow removal path according to coordinate data provided by the location navigation module; and wherein the location navigation module is detachably mounted on the automatic moving snow removal device.

2 . The automatic moving snow removal device according to claim 1 , wherein the map of the preset border is formed by continuous coordinates formed in a manner that the location navigation module moves for a circle along the border of a working area.

3 . The automatic moving snow removal device according to claim 1 , wherein the preset border is an electrified wire disposed along the border of the working area.

4 . The automatic moving snow removal device according to claim 3 , wherein the location navigation module is a satellite location navigation module, the automatic moving snow removal device further comprises a position detection module, the position detection module is configured to detect a relative position relationship between the automatic moving snow removal device and the electrified wire, the control module calculates relative coordinates of the automatic moving snow removal device by dead reckoning according to the information detected by the position detection module, and performs absolute location and error elimination according to the coordinates of the satellite location navigation module, to obtain the map of the preset border formed by continuous coordinates of the automatic moving snow removal device along the electrified wire.

5 . The automatic moving snow removal device according to claim 1 , wherein the location navigation module is an ultra wide band location module, at least two ultra wide band labels are disposed inside or outside the preset border, the ultra wide band location module calculates relative coordinates of two positions of the automatic moving snow removal device by the at least two ultra wide band labels, the ultra wide band location module moves for a circle along the border of the moving area to form two continuous relative coordinates relative to the ultra wide band labels, and the two continuous relative coordinates form the map of the preset border.

6 . The automatic moving snow removal device according to claim 1 , wherein the automatic moving snow removal device further comprises a dip angle detection module, the dip angle detection module is configured for detecting a dip angle of the automatic moving snow removal device, the location navigation module can record the coordinate value of each point when the automatic moving snow removal device moves along a preset area, the dip angle detection module records the dip angle value of each point, and the control module generates the border map in a 3D form according to the coordinate values and the dip angle values.

7 . The automatic moving snow removal device according to claim 1 , wherein the snow removal path is a path toward one direction or reciprocates back and forth along an extending direction parallel with a road.

8 . The automatic moving snow removal device according to claim 1 , wherein the snow removal path is a path toward one direction or reciprocates back and forth along an extending direction vertical to a road.

9 . The automatic moving snow removal device according to claim 1 , wherein the snow removal path comprises at least one snow piling point.

10 . The automatic moving snow removal device according to claim 1 , wherein the snow removal path contains a fixed snow throwing direction.

11 . The automatic moving snow removal device according to claim 1 , wherein the map of the preset border comprises at least two different areas, and the control module can execute different control modes according to the marks of different areas.

12 . The automatic moving snow removal device according to claim 11 , wherein the at least two different areas comprise at least one snow removal area, and one or more of an intersection area, a lawn area, an island area and a narrow passage area.

13 . The automatic moving snow removal device according to claim 12 , wherein the control module defaults that the snow removal is required for the snow removal area, no snow removal is required for the island area, and the snow removal is selective for other areas.

14 . The automatic moving snow removal device according to claim 11 , wherein the at least two different areas comprise at least two snow removal areas and a connecting passage area between the two snow removal areas.

15 . The automatic moving snow removal device according to claim 14 , wherein the control module defaults that the snow removal is required for the snow removal areas, and the snow removal is selective for the connecting passage area.

16 . The automatic moving snow removal device according to claim 1 , wherein the automatic moving snow removal device further comprises a working alarm device, and if the automatic moving snow removal device enters a set area and/or reaches preset alarm time, the control module controls the working alarm device to alarm.

17 . The automatic moving snow removal device according to claim 1 , wherein the control module controls the automatic moving snow removal device to move to a preset site after the automatic moving snow removal device moves along all the snow removal paths completely.

18 . The automatic moving snow removal device according to claim 1 , wherein the automatic moving snow removal device further comprises a heating thermal insulation device, and the heating thermal insulation device can be repeatedly heated by electric energy and keeps at least part of the energy module and/or the control module at a preset temperature.

19 . The automatic moving snow removal device according to claim 18 , wherein the heating thermal insulation device comprises an electric heating thermal insulation material at least partially covering a housing of the automatic moving snow removal device, and/or the energy module, and/or the control module of the automatic moving snow removal device;
the electric heating thermal insulation material is electrified for heating during energy supplement of the automatic moving snow removal device, and performs thermal insulation during working of the automatic moving snow removal device.
