[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] like Figure 1-5 As shown, the photovoltaic power generation component cleaning device of the photovoltaic power station includes a support frame 1 installed on the back of the photovoltaic power generation panel, a slide groove 2 is opened on the top of the support frame 1, a rack 16 is inserted in the slide groove 2, the rack 16 is engaged with a gear 10 slidably connected to the slide groove 2, the gear 10 extends downward and is movably connected to the fan 4 slidably connected to the support frame 1, the bottom end of the fan shaft of the fan 4 is fixedly connected to a pin shaft 17, the outer side of the pin shaft 17 is provided with a sleeve 11 fixedly connected to the fan 4, the outer side wall of the sleeve 11 is rotatably connected to two rotating frames 5 distributed in a V shape and staggered, the rotating frame 5 is hollow at one end away from the fan 4, and is provided with two spring rods 14, one of the spring rods 14 is slidably inserted in the hollow of the rotating frame 5, and a cleaning pipe 7 is fixedly installed at its telescopic end, a plurality of air outlet holes 12 are opened on the surface of the cleaning pipe 7, and a hose 9 is installed between the pipe mouth of the cleaning pipe 7 and the air outlet of the fan 4, a motor 3 is slidably connected to the support frame 1, and the main shaft of the motor 3 is fixed to the gear 10.

[0025] By adopting this technical solution, a fan 4, a hose 9 and a cleaning pipe 7 are set up, so that the gas blown out by the fan 4 can be transported through the hose 9 and sent into the cleaning pipe 7. The setting of the air outlet 12 can achieve the effect of blowing the gas out of the cleaning pipe 7. The specific working method is that the motor 3 drives the gear 10 to rotate, and the rotation of the gear 10 causes the gear 10 to move along the rack 16, thereby driving the rotating frame 5 below it to move. The movement of the rotating frame 5 drives the cleaning pipe 7 to move on the photovoltaic power generation panel. At the same time, the rotation of the gear 10 drives the fan 4 and the pin shaft 17 to rotate. The rotation of the fan 4 can blow out gas, and then through the transportation of the hose 9, the cleaning pipe 7 can continuously blow out gas when moving, thereby achieving the effect of preventing diffused dust from falling back on the surface of the photovoltaic power generation panel during the cleaning process.

[0026] like Figure 2 and Figure 3 As shown, the rotating frame 5 is provided with a plurality of rotating brushes 8 distributed in a linear array along the length direction of the rotating frame 5. The brush handle portion of the rotating brush 8 is located on the upper surface of the rotating frame 5, and the brush head portion of the rotating brush 8 extends downward to the bottom of the rotating frame 5. Sprockets are fixed to the outside of the brush handles of the plurality of rotating brushes 8. Several sprockets located on the same rotating frame 5 are engaged with chains, and pulleys are also fixed to the brush handle portions of the two rotating brushes 8 near the pin shaft 17 and the outside of the pin shaft 17. The pulleys installed at the rotating brushes 8 are respectively equipped with belt transmission with the pulleys installed at the pin shaft 17.

[0027] By adopting this technical solution, the rotating brush 8 is driven to rotate by setting the pin shaft 17, so that when the rotating frame 5 moves, all the rotating brushes 8 will continue to rotate, thereby continuously cleaning the dust on the surface of the photovoltaic panel. In addition, several protrusions are provided on the rotating frame 5 to support the chain to prevent the several sprockets and chains located in the middle from falling off.

[0028] like Figure 4 As shown, a gearbox 13 is provided between the gear 10 and the fan 4 , the input shaft of the gearbox 13 is fixed to the gear 10 , and the output shaft is fixed to the top end of the blade shaft of the fan 4 .

[0029] By adopting this technical solution, by setting up a gearbox 13, the gear 10 can be accelerated by the gearbox 13 when rotating at a lower speed, thereby driving the fan shaft and the pin shaft 17 of the fan 4 to rotate at high speed, so that the device is relatively slow in overall displacement, while the fan 4 and the rotating brush 8 in the device rotate faster.

[0030] like Figure 1 、 Figure 2 and Figure 3 As shown, an electric telescopic rod 6 is movably installed between the sleeve 11 and the cleaning tube 7.

[0031] By adopting this technical solution, the angle at which the two rotating frames 5 are rotated and opened around the sleeve 11 can be adjusted by setting an electric telescopic rod 6, thereby adjusting the range that the rotating brush 8 can clean. The specific working method is that the electric telescopic rod 6 is extended and retracted, driving the cleaning tube 7 to move relative to the pin shaft 17. When the cleaning tube 7 moves relatively, the rotating frame 5 is driven to rotate at the sleeve 11. At this time, the spring rod 14 slidably inserted in the hollow part of the rotating frame 5 will also slide along the length direction of the hollow part of the rotating frame 5 under the extension and retraction drive of the electric telescopic rod 6, and during the sliding process of the spring rod 14, the cylinder end face of the spring rod 14 is always parallel to the plane where the rotating frame 5 is located. In addition, the cylinder end of the electric telescopic rod 6 is fixedly plugged into the cleaning tube 7, and its telescopic end is fixedly plugged into the sleeve 11.

[0032] like Figure 3 The cylinder part of the other spring rod 14 is fixed to the bottom end of the rotating frame 5, and the telescopic end is rotated downward and connected to the wheel 15 that rolls on the back of the photovoltaic panel.

[0033] By adopting this technical solution, another spring rod 14 and a wheel 15 are set to act on the back of the photovoltaic panel, so that the relative position of the cleaning tube 7 and the upper surface of the photovoltaic panel is constant. Specifically, the other spring rod 14 is extended to the back of the photovoltaic panel, and one of the spring rods 14 is contracted so that the cleaning tube 7 is located on the front of the photovoltaic panel. At this time, the other spring rod 14 is contracted due to the recovery force of the spring, and one of the spring rods 14 is extended due to the recovery force of the spring, which will squeeze the surface of the photovoltaic panel, thereby increasing the squeezing force between the cleaning tube 7 and the photovoltaic panel, so that the cleaning tube 7 wipes the surface of the photovoltaic panel.

[0034] Working principle: Start the motor 3 to drive the gear 10 to rotate. The rotation of the gear 10 drives the device to move along the slide 2, and the rotating frame 5 will also move with it, driving the cleaning tube 7 to move on the photovoltaic panel. At the same time, the rotation of the gear 10 drives the fan 4 and the pin 17 to rotate. The rotation of the fan 4 can blow out gas, and then through the hose 9, the cleaning tube 7 can continuously blow out gas when moving, and the rotation of the pin 17 can drive the rotating brush 8 to rotate, so that when the rotating frame 5 moves, all the rotating brushes 8 will also rotate continuously, thereby continuously cleaning the dust on the surface of the photovoltaic panel.

[0035] The wiring diagram of the motor 3, the gearbox 13 and the electric telescopic rod 6 in the present invention is common knowledge in the field, and its working principle is a well-known technology. The models are selected according to the actual use. Therefore, the control method and wiring arrangement of the motor 3, the gearbox 13 and the electric telescopic rod 6 are not explained in detail.

[0036] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
