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 a specific work of the automatic moving snow removal device;
a moving module, configured to drive the automatic moving snow removal device to move on a ground; and
a control module, configured to:
control the working module and the moving module of the automatic moving snow removal device, to cause the automatic moving snow removal device to move and work within a preset border;
generate a snow removal path according to a map of the preset border, wherein the map of the preset border comprises at least two different areas, and the at least two different areas comprise at least one snow removal area and at least one of an intersection area, a lawn area, an island area or a narrow passage area;
execute different control modes according to corresponding marks of the at least two different areas; and
control the automatic moving snow removal device to move along the snow removal path according to coordinate data provided by a location navigation module.

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 a 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 a border of a working area.

4. The automatic moving snow removal device according to claim 3 , wherein:
the location navigation module comprises a satellite location navigation module,
the automatic moving snow removal device further comprises a position detection module configured to detect a relative position relationship between the automatic moving snow removal device and the electrified wire,
the control module is further configured to:
calculate relative coordinates of the automatic moving snow removal device by dead reckoning according to information detected by the position detection module, and
perform absolute location and error elimination according to 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 comprises 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 is configured to calculate relative coordinates of two positions of the automatic moving snow removal device by the at least two ultra wide band labels, and move for a circle along a border of a 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 , further comprising:
a dip angle detection module configured to detect a dip angle of the automatic moving snow removal device, wherein:
the location navigation module is configured to record a coordinate value of each point when the automatic moving snow removal device moves along a preset area,
the dip angle detection module is further configured to record a dip angle value of each point, and
the control module is further configured to generate a border map in a 3D form according to the coordinate value and the dip angle value of each point.

7. The automatic moving snow removal device according to claim 1 , wherein the snow removal path comprises 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 comprises 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 control module is further configured to default a snow removal to be required for the snow removal area, no snow removal to be required for the island area, and the snow removal to be selective for other areas.

12. The automatic moving snow removal device according to claim 1 , wherein the at least two different areas comprise at least two snow removal areas and a connecting passage area between the at least two snow removal areas.

13. The automatic moving snow removal device according to claim 12 , wherein the control module is further configured to default a snow removal to be required for the at least two snow removal areas, and the snow removal to be selective for the connecting passage area.

14. 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 a preset alarm time, the control module is further configured to control the working alarm device to alarm.

15. The automatic moving snow removal device according to claim 1 , wherein the control module is further configured to control 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.

16. The automatic moving snow removal device according to claim 1 , further comprising: an energy module configured to provide energy for the moving module and the working module of the automatic moving snow removal device.

17. The automatic moving snow removal device according to claim 16 , wherein the automatic moving snow removal device further comprises a heating thermal insulation device configured to be repeatedly heated by electric energy and keep at least part of the energy module and/or the control module at a preset temperature range.

18. The automatic moving snow removal device according to claim 17 , wherein the heating thermal insulation device comprises an electric heating thermal insulation material at least partially covering one or more of a housing of the automatic moving snow removal device, and/or the energy module, or the control module; and
the electric heating thermal insulation material is electrified for heating during energy supplement of the automatic moving snow removal device, and is configured to perform thermal insulation during working of the automatic moving snow removal device.
