The water collecting tank is arranged on the support column. The spray pipe is arranged on one side of the solar cell panel and is connected to the water collecting tank through the water pump. The water pump is electrically connected to the battery pack.

[0007] By adopting the above technical solution, the power generating fan blades rotate under the drive of wind, and the rotation of the power generating fan blades will drive the transmission assembly to rotate. The transmission assembly drives the cleaning brush to move above the solar panel through the moving parts to sweep away the dust on its surface. When the cleaning brush is cleaning the solar panel, the water pump is turned on to pump the water in the water collection tank to the spray pipe, spraying water on the solar surface, improving the cleaning effect, eliminating the need for workers to clean laboriously, reducing the workers' work intensity, and improving the cleaning efficiency.

The rack is arranged on the mounting frame along the extension direction of the guide rod, and the rotating gear is coaxially fixedly connected to the rotating shaft of the cleaning brush and meshingly connected with the rack.

DETAILED DESCRIPTION

[0025] The following is combined with Figure 1-4 This application is described in further detail.

[0026] Reference Figure 1 and Figure 2A wind-solar complementary street lamp disclosed in an embodiment of the present application includes a street lamp body 1, a cleaning component 2, a transmission component 3 and a water spray component 4. The street lamp body 1 includes a support column 11, a lighting lamp 12, a power-generating fan blade 13, a solar panel 14 and a battery pack. The support column 11 is a long rectangular body or a cylinder, which is fixedly installed on the ground in a vertical direction. The lighting lamp 12 is fixedly installed on the upper side wall of the support column 11. A fixing rod 131 is fixedly installed on the top of the support column 11. The power-generating fan blade 13 is rotatably connected to the fixing rod 131, and can convert wind energy into electrical energy and store it in the battery pack. The solar panel 14 is obliquely installed on the upper side wall of the support column 11, and can convert light energy into electrical energy and store it in the battery pack. The battery pack is installed inside the support column 11 and is electrically connected to the lighting lamp 12. A mounting frame 5 is fixedly mounted on the periphery of the solar panel 14 , the cleaning assembly 2 is arranged on the mounting frame 5 , the transmission assembly 3 is driven by the rotating shaft of the power generation fan blade 13 , and the water spraying assembly 4 is used to spray water onto the surface of the solar panel 14 .

[0027] Reference Figure 2 The cleaning assembly 2 includes a cleaning brush 21, a moving member 22 and a rotating member 23, wherein the moving member 22 includes a rotating rod 221, a guide rod 222 and two mounting blocks 223, the rotating rod 221 is a reciprocating screw, the rotating rod 221 is rotatably connected to the end of the mounting frame 5 away from the ground, the guide rod 222 is a long cylindrical body, both ends of which are welded to the mounting frame 5, and the guide rod 222 is arranged at the end of the solar panel 14 away from the rotating rod 221. Both mounting blocks 223 are square bodies, one of which is threadedly connected to the rotating rod 221, and the other is slidably connected to the guide rod 222, and both ends of the cleaning brush 21 are rotatably connected to the two mounting blocks 223.

[0028] The rotating member 23 includes a rack 231 and a rotating gear 232. The rack 231 is welded to the mounting frame 5. The extending direction of the rack 231 is the same as the extending direction of the guide rod 222. The rotating gear 232 is coaxially fixedly connected to the rotating shaft of the cleaning brush 21 and meshingly connected with the rack 231.

[0029] When the solar panel 14 needs to be cleaned, the rotating rod 221 is rotated to drive the mounting block 223 to drive the cleaning brush 21 to move back and forth along the setting direction of the guide rod 222. At the same time, the rotating gear 232 will rotate under the drive of the rack 231, driving the cleaning brush 21 to rotate along its own axis while moving, thereby sweeping up the dust on the surface of the solar panel 14.

[0030] Reference Figure 2 , Figure 3 and Figure 4The transmission assembly 3 includes a first synchronous pulley 31, a second synchronous pulley 32 and a synchronous belt 33. The first synchronous pulley 31 is arranged at the connection between the fixed rod 131 and the rotating shaft of the power generation fan blade 13, that is, one end of the first synchronous pulley 31 is sleeved on the fixed rod 131, and the other end is sleeved on the rotating shaft of the power generation fan blade 13. The second synchronous pulley 32 is coaxially fixedly connected to the rotating rod 221, and the synchronous belt 33 is wound around the first synchronous pulley 31 and the second synchronous pulley 32. It should be noted that a receiving groove 132 is provided on the side wall of the rotating shaft of the power generation fan blade 13. In the present embodiment, three receiving grooves 132 are arranged along the rotating axis of the power generation fan blade 13. A connecting spring 6 and a plug-in block 7 are arranged in each receiving groove 132. One end of the connecting spring 6 is welded to the inner bottom wall of the receiving groove 132, and the other end is welded to the side wall of the plug-in block 7. The plug-in block 7 is a square body. A key groove 311 for accommodating the insertion of the plug-in block 7 is provided on the inner wall of one end of the shaft hole of the first synchronous pulley 31 close to the power generation fan blade 13.

[0031] When the wind is strong, the rotation speed of the power generation blade 13 is accelerated, and the plug block 7 will extend from the receiving groove 132 under the action of centrifugal force, the connecting spring 6 is in a stretched state, and the plug block 7 is embedded in the key groove 311, thereby driving the first synchronous pulley 31 to rotate, and the first synchronous pulley 31 drives the synchronous belt 33 and the second synchronous pulley 32 to rotate, driving the cleaning brush 21 to clean the surface of the solar panel 14. When the wind is weak, the rotation speed of the power generation blade 13 is slow, and the plug block 7 stays in the receiving groove 132 under the elastic force of the connecting spring 6, and the first synchronous pulley 31 will not rotate with the rotating shaft of the power generation blade 13, so as to prevent the reciprocating movement of the cleaning brush 21 from affecting the solar panel 14 to absorb sunlight.

[0032] Reference Figure 2 and Figure 3 The water spray assembly 4 includes a water collecting tank 41, a spray pipe 42 and a water pump 43. The water collecting tank 41 is a hollow square body, which is sleeved on the upper part of the support column 11. The top of the water collecting tank 41 is provided with a plurality of filter holes 411. When it rains, rainwater can flow into the water collecting tank 41 through the filter holes 411. The filter holes 411 can prevent external impurities from entering the water collecting tank 41, which is convenient for the secondary use of rainwater. The spray pipe 42 is mounted on the mounting frame 5 and is located above the solar panel 14. One end of the spray pipe 42 is connected to the water collecting tank 41 through the water pump 43. The water pump 43 is electrically connected to the battery pack, and no additional power supply is required. It should be noted that since the solar panel 14 is installed at an angle, the spray pipe 42 in this embodiment is arranged at the end of the solar panel 14 away from the ground. When spraying, water can flow down along the tilt direction of the solar panel 14 to flush most of the surface of the solar panel 14.

[0033] In addition, an infrared sensor 8 is fixedly installed on the mounting frame 5, and the infrared sensor 8 is electrically connected to the water pump 43 through the controller. In this embodiment, the infrared sensor 8 is installed at one end of the mounting frame 5 close to the rotating rod 221, and can detect the displacement of the mounting block 223. When the infrared sensor 8 detects that the mounting block 223 is approaching, the controller controls the water pump 43 to start, and pumps the water 43 in the water collecting tank 41 to the spray pipe 42, and the spray pipe 42 sprays it to the surface of the solar cell panel 14. In other words, the spray pipe 42 sprays water intermittently to reduce water resource consumption.

[0034] The implementation principle of a wind-solar complementary street lamp in an embodiment of the present application is as follows: when the wind is strong, the rotation speed of the power generation blades 13 is accelerated, and the plug-in block 7 will move in a direction away from the inner bottom wall of the accommodating groove 132 under the action of centrifugal force, and be embedded in the key groove 311. The first synchronous pulley 31 rotates along the rotating shaft of the power generation blades 13, and the synchronous belt 33 and the second synchronous pulley 32 also rotate accordingly. The second synchronous pulley 32 will drive the rotating rod 221 to rotate, driving the mounting block 223 to drive the cleaning brush 21 to reciprocate along the setting direction of the guide rod 222. At the same time, the rotating gear 232 will rotate under the drive of the rack 231, driving the cleaning brush 21 to rotate along its own axis while moving, thereby sweeping up the dust on the surface of the solar cell panel 14.

[0035] When the infrared sensor 8 detects that the mounting block 223 is approaching, the controller will control the water pump 43 to start, pump the water in the water collection tank 41 to the spray pipe 42, and the spray pipe 42 will spray the rainwater collected in the water collection tank 41 to the surface of the solar panel 14. As the mounting block 223 reciprocates, the spray pipe 42 will intermittently spray the rainwater collected in the water collection tank 41 to the surface of the solar panel 14 for washing. In addition, the cleaning brush 21 can achieve a good cleaning effect, and there is no need for workers to clean it, which reduces the work intensity of workers and improves cleaning efficiency.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
