Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figure 1-8 , the present invention provides the following technical solutions: A wind measurement lidar with a self-cleaning function, including a body 1, heat dissipation ports 2 are arranged on both sides of the body 1, a glass window 3 is arranged on the top of the body 1, a fixing frame 4 is connected to the top of the body 1, one end of the fixing frame 4 is connected to a mounting cover 5, and a motor 6 is installed inside the mounting cover 5;

[0032] The output end of the motor 6 is connected to a first lead screw 7, the outer wall of the first lead screw 7 is threadedly connected to a first connecting block 8, the outer wall of the first connecting block 8 is connected to a mounting frame 9, a silica gel scraping strip 10 and a water spraying pipe 13 are arranged at the bottom of the mounting frame 9, a chute 11 is opened at the top of the fixing frame 4, a slider 12 is connected to the top of the first connecting block 8, a nozzle 14 is arranged at the bottom of the water spraying pipe 13, a water tank 15 is installed on the back of the body 1, and a pumping pump 16 is installed inside the water tank 15;

[0033] It should be noted that the wiring terminals of the motor 6 and the pumping pump 16 are connected to the power supply and the control switch.

[0034] Preferably: One end of the first lead screw 7 is rotationally connected to the fixing frame 4 through a bearing, the first connecting block 8 can be slidably connected to the fixing frame 4 through the chute 11 and the slider 12, and the bottom of the silica gel scraping strip 10 is in contact with the surface of the glass window 3.

[0035] During specific use, the motor 6 drives the first lead screw 7 to rotate reciprocally, enabling the first connecting block 8 threadedly connected to its outer wall to move along the chute 11 under the action of the slider 12. It also drives the silica gel wiper strip 10 and the nozzle 14 to move together. Meanwhile, the water pump 16 is started to pump the water in the water tank 15 to the water spray pipe 13, and the nozzle 14 sprays water onto the surface of the glass window 3. Then, in cooperation with the silica gel wiper strip 10 scraping the surface of the glass window 3 reciprocally, the self-cleaning of the surface of the glass window 3 can be realized.

[0036] Preferably: A connecting plate 17 is connected to the top of the silica gel wiper strip 10. Two insertion blocks 18 are connected to the top of the connecting plate 17. Card slots 19 are formed on the outer walls of the two insertion blocks 18. Two insertion slots 20 are formed on the surface of the mounting frame 9. A mounting seat 21 is connected to the top of the mounting frame 9. A spring 22 is arranged inside the mounting seat 21. An end of the spring 22 is connected to a movable block 23. One end of the movable block 23 is connected to a latch 24. One end of the insertion block 18 can penetrate through the mounting frame 9 through the insertion slot 20. The silica gel wiper strip 10 and the mounting frame 9 can form an elastic clamping structure through the connecting plate 17, the insertion block 18, the card slot 19, the insertion slot 20, the mounting seat 21, the spring 22, the movable block 23, and the latch 24.

[0037] During specific use, the movable block 23 is driven by the dial to drive the latch 24 to contract. At this time, one end of the latch 24 will disengage from the card slot 19 on the outer wall of the insertion block 18. Then, the connecting plate 17 is pulled downward to enable the insertion block 18 to disengage from the insertion slot 20, so that the removal of the silica gel wiper strip 10 can be realized.

[0038] It should be noted that the silica gel wiper strip 10 is made of a flexible material, so it can be bent during disassembly.

[0039] On the contrary, when installing the silica gel wiper strip 10, the movable block 23 is driven by the dial to drive the latch 24 to contract. Then, the insertion block 18 is inserted into the insertion slot 20 from the bottom of the mounting frame 9. Then, by releasing the dial, the latch 24 can pop out under the action of the spring 22 and be inserted into the card slot 19 to achieve fixation.

[0040] Preferably: Two connecting seats 25 are connected to the bottom of the machine body 1. The second lead screw 26 is rotatably connected to the inner sides of the four connecting seats 25. A second connecting block 27 is threadedly connected to the outer wall of the second lead screw 26. A support frame 28 is connected to the bottom of the second connecting block 27. A support leg 29 is connected to the bottom of the support frame 28. A rotating rod 31 penetrates through the outer wall of the connecting seat 25. One end of the rotating rod 31 is connected to an adjusting knob 33. One end of the second lead screw 26 is connected to a first bevel gear 30. One end of the rotating rod 31 is connected to a second bevel gear 32. The first bevel gear 30 and the second bevel gear 32 are meshed with each other.

[0041] It should be noted that the four connection seats 25 are located at the four corners of the bottom of the body 1 , an opening is provided at the bottom of the connection seat 25 , and one end of the support frame 28 can penetrate the connection seat 25 through the bottom opening of the connection seat 25 .

[0042] When in use, the rotating rod 31 is rotated by adjusting the knob 33, and then the meshing relationship between the first bevel gear 30 and the second bevel gear 32 is used to drive the second screw rod 26 to rotate, so that the second connecting block 27 threadedly connected to the outer wall can drive the support frame 28 to rise and fall, and the support legs 29 at the bottom of the support frame 28 will rise and fall together, so that the support legs 29 at the four corners can be adjusted separately in the above manner, so as to facilitate the leveling of the wind laser radar;

[0043] It should be noted that when the adjustment knob 33 is rotated clockwise, the second connecting block 27 will drive the support leg 29 at the bottom of the support frame 28 to rise. Conversely, when the adjustment knob 33 is rotated counterclockwise, the second connecting block 27 will drive the support leg 29 at the bottom of the support frame 28 to fall.

[0044] Working principle: First, when the surface of the glass window 3 needs to be cleaned during the monitoring process, the motor 6 drives the first screw rod 7 to rotate back and forth, so that the first connecting block 8 with a threaded connection on its outer wall can move along the slide groove 11 under the action of the slider 12, and will also drive the silicone scraper 10 and the nozzle 14 to move together. At the same time, the pump 16 is started to pump the water in the water tank 15 to the water spray pipe 13, and the nozzle 14 will spray the surface of the glass window 3, and then cooperate with the silicone scraper 10 to scrape the surface of the glass window 3 back and forth, so as to achieve self-cleaning of the surface of the glass window 3, avoid dust affecting the penetration of the infrared laser beam of the laser radar, and drive the card by moving the movable block 23 through the shifting block. The pin 24 contracts, and one end of the pin 24 will disengage from the slot 19 on the outer wall of the plug block 18. Then the connecting plate 17 is pulled downward to allow the plug block 18 to disengage from the slot 20, thereby enabling the silicone scraper 10 to be removed for subsequent replacement. Finally, the rotating rod 31 is rotated by adjusting the knob 33, and then the meshing relationship between the first bevel gear 30 and the second bevel gear 32 is used to drive the second screw rod 26 to rotate, so that the second connecting block 27 threadedly connected to its outer wall can drive the support frame 28 to rise and fall, and the support legs 29 at the bottom of the support frame 28 will rise and fall together. In this way, the support legs 29 at the four corners can be adjusted separately to facilitate the leveling of the wind measuring laser radar.
