[0051] A photovoltaic power station is a power station that uses the photovoltaic effect of photovoltaic cells to directly convert solar radiation energy into electrical energy.

[0052] An embodiment of the present utility model provides a photovoltaic power station, including a photovoltaic array, an inverter, a transformer and a distribution system. The photovoltaic array includes a plurality of photovoltaic power generation devices arranged in an array, the photovoltaic power generation devices are electrically connected to the inverter, the transformer is electrically connected to the inverter, and the distribution system is electrically connected to the transformer.

[0053] Photovoltaic power generation devices can receive sunlight and use the photovoltaic effect to convert photons into electrons to generate direct current. The inverter can convert the direct current generated by the photovoltaic power generation device into alternating current. The transformer can increase or decrease the voltage of the alternating current output by the inverter so that it can be transmitted to the distribution system. The distribution system can supply the electric energy transmitted by the transformer to users.

[0054] Photovoltaic power generation devices are usually installed outdoors. Dust, dirt, bird droppings and other impurities are easily accumulated on the photovoltaic power generation devices. These impurities will reduce the transmittance of light. If these impurities are not cleaned, the photovoltaic power generation device's efficiency in absorbing solar energy will decrease, thereby reducing its power generation.

[0055] In the related technology, the photovoltaic power generation device includes a mounting frame, a driving mechanism and a cleaning mechanism. The cleaning mechanism includes a moving block, a cleaning rod and a water supply pipe. The moving block is connected to the driving mechanism, and one end of the cleaning rod is connected to the moving block. The driving mechanism drives the cleaning rod to move through the moving block to scrape off impurities on the surface of the photovoltaic panel. The water supply pipe is used to spray water onto the surface of the photovoltaic panel.

[0056] However, when impurities adhere to the photovoltaic panel and have strong adhesion to the surface of the photovoltaic panel, it is difficult to scrape them off with the cleaning rod.

[0057] For the above technical issues, please refer to Figures 1 to 3 An embodiment of the utility model provides a photovoltaic power generation device, including: a photovoltaic bracket 100; a photovoltaic panel 200, the photovoltaic panel 200 is arranged on the photovoltaic bracket 100; a driving mechanism 300, the driving mechanism 300 is arranged on the photovoltaic panel 200; a cleaning mechanism 400, the cleaning mechanism 400 includes a connecting component 410 connected to the output end of the driving mechanism 300, a vibrating member 420 connected to the connecting component 410 and a cleaning component 430 connected to the vibrating member 420, the cleaning end of the cleaning component 430 can contact the surface of the photovoltaic panel 200; the vibrating member 420 drives the cleaning component 430 to vibrate, and the driving mechanism 300 drives the vibrating member 420 to move through the connecting component 410, so as to drive the cleaning component 430 to move on the surface of the photovoltaic panel 200.

[0058] By placing the photovoltaic panel 200 on the photovoltaic support 100 , the photovoltaic support 100 can support the photovoltaic panel 200 .

[0059] By arranging the driving mechanism 300 on the photovoltaic panel 200 , the photovoltaic panel 200 can support the driving mechanism 300 .

[0060] By setting up a cleaning mechanism 400, the cleaning mechanism 400 includes a connecting component 410 connected to the output end of the driving mechanism 300, a vibrating member 420 connected to the connecting component 410 and a cleaning component 430 connected to the vibrating member 420. The cleaning end of the cleaning component 430 can contact the surface of the photovoltaic panel 200, and the driving mechanism 300 can support the connecting component 410, the vibrating member 420 and the cleaning component 430; and the driving mechanism 300 can drive the vibrating member 420 to move through the connecting component 410 to drive the cleaning component 430 to move on the surface of the photovoltaic panel 200, so that the cleaning component 430 can clean impurities on the surface of the photovoltaic panel 200; in addition, the vibrating member 420 can drive the cleaning component 430 to vibrate to reduce the adhesion of impurities to the surface of the photovoltaic panel 200, so that the cleaning component 430 can clean impurities with strong adhesion to the surface of the photovoltaic panel 200, and the cleaning effect of the cleaning component 430 is good.

[0061] The preferred technical solution of the photovoltaic power generation device of the present invention is described below with reference to the accompanying drawings.

[0062] In some embodiments, see Figure 3 and Figure 5 The connecting component 410 includes: a frame 411, the frame 411 is connected to the output end of the driving mechanism 300, the frame 411 has a accommodating cavity 412, the vibrating member 420 is arranged in the accommodating cavity 412, and at least part of the cleaning end is located outside the accommodating cavity 412; a limiting member 413, the limiting member 413 is connected to the frame 411, the limiting member 413 is located in the accommodating cavity 412, the limiting member 413 and the frame 411 together form a vibration area 414, and a part of the cleaning component 430 is located in the vibration area 414, so that the cleaning component 430 vibrates in the vibration area 414.

[0063] In this embodiment, the frame 411 is connected to the output end of the driving mechanism 300, and the driving mechanism 300 is capable of driving the frame 411 to move. The frame 411 has a housing 412 therein, which can be used to accommodate the vibrating member 420 and the cleaning assembly 430. The housing 412 has an opening facing the photovoltaic panel 200, and at least a portion of the cleaning end of the cleaning assembly 430 extends out of the opening, so that the cleaning end of the cleaning assembly 430 can contact the surface of the photovoltaic panel 200 to clean the surface of the photovoltaic panel 200.

[0064] Furthermore, the vibrating member 420 is connected to the cavity wall of the accommodating cavity 412 by welding, screwing, or riveting, or a placement plate (not shown) is provided on the cavity wall of the accommodating cavity 412, and the vibrating member 420 is connected to the placement plate to achieve the installation of the vibrating member 420. It should be noted that the present invention does not limit the specific connection method between the vibrating member 420 and the accommodating cavity 412, and it can be adjusted according to actual needs.

[0065] In addition, by setting a limiter 413, the limiter 413 is connected to the frame 411, and the limiter 413 is located in the accommodating cavity 412. The limiter 413 and the frame 411 together form a semi-open vibration area 414, and a part of the cleaning component 430 is set in the vibration area 414. The vibration area 414 can limit the displacement range of the cleaning component 430 located in the vibration area 414. The cleaning component 430 is an integral structure, and the vibration area 414 can limit the displacement range of the entire cleaning component 430, which makes the cleaning component 430 vibrate only in the vibration area 414, thereby preventing damage to the cleaning component 430, the vibration component 420 or the photovoltaic panel 200 due to the excessive vibration range of the cleaning component 430.

[0066] In some specific implementations, see Figure 5The limiting member 413 includes a mounting plate 4131 connected to the frame 411 and a connecting plate 4132 protruding from the mounting plate 4131 in the direction of movement of the cleaning mechanism 400. The frame 411, the mounting plate 4131, and the connecting plate 4132 collectively define a vibration region 414. Specifically, the limiting member 413 is L-shaped. By positioning a portion of the cleaning assembly 430 between the frame 411 and the connecting plate 4132, the frame 411 and the connecting plate 4132 can limit the position of the cleaning assembly 430.

[0067] It should be noted that a portion of the cleaning component 430 is a structure protruding along the moving direction of the cleaning component 430. This protruding structure is located between the frame 411 and the connecting plate 4132, and the frame 411 and the connecting plate 4132 can limit it.

[0068] Furthermore, in the present invention, the length of the cleaning assembly 430 generally needs to cover the length of the photovoltaic panel 200, while the vibrating member 420 is often relatively small. When the cleaning assembly 430 is heavy, the vibrating member 420 may not be able to provide adequate support for the cleaning assembly 430. Therefore, in this embodiment, a portion of the cleaning assembly 430 is disposed between the frame 411 and the connecting plate 4132, and the connecting plate 4132 is disposed below the cleaning assembly 430, so that the connecting plate 4132 can support the cleaning assembly 430, thereby reducing the load on the vibrating member 420.

[0069] In other specific embodiments, see Figure 6 The number of the limiting members 413 is set to two, and the two limiting members 413 are relatively arranged on the frame 411. Each limiting member 413 forms a vibration area 414 relatively arranged with the frame 411. There are raised structures on the opposite sides of the cleaning component 430 to make the cleaning component 430 have a T-shaped structure. The two raised structures are correspondingly arranged in the two vibration areas 414. The limiting members 413 can not only limit the displacement of the cleaning component 430 in the up and down vibration, but also limit the displacement of the cleaning component 430 in the left and right swinging. Moreover, the two limiting members 413 have a better supporting effect on the cleaning component 430.

[0070] In some examples, the vibration member 420 is a vibration motor, which has good vibration effect and low cost.

[0071] In other embodiments, see Figure 4 The cleaning component 430 includes: a spray part 431, the spray part 431 is connected to the vibrating part 420, the spray part 431 has a spray cavity 432, the spray part 431 has a plurality of spray holes 433 connected to the spray cavity 432; bristles 434, the bristles 434 are arranged on the spray part 431.

[0072] In this embodiment, the spray chamber 432 is used to contain cleaning liquid, which can flow onto the photovoltaic panel 200 through the spray hole 433. When the driving mechanism 300 drives the cleaning mechanism 400 to move, the bristles 434 can clean impurities on the photovoltaic panel 200.

[0073] Furthermore, when the vibration motor drives the cleaning component 430 to vibrate, the bristles 434 can shake on the surface of the photovoltaic panel 200, which can shake off impurities with strong adhesion on the surface of the photovoltaic panel 200, thereby making the cleaning effect of the cleaning component 430 better.

[0074] In some specific implementations, see Figure 4 The bristles 434 are arranged around the spray hole 433, and the cleaning liquid in the spray chamber 432 first flows through the spray hole 433 to the photovoltaic panel 200 to wet the impurities on the photovoltaic panel 200 so that the bristles 434 can brush them.

[0075] In other specific embodiments (not shown in the figure), the bristles 434 are arranged in the spray hole 433. The cleaning liquid flows out of the spray hole 433 and directly contacts the bristles 434 before flowing onto the photovoltaic panel 200. The bristles 434 can contact the cleaning liquid more fully, which can enhance the cleaning effect of the bristles 434.

[0076] Further, see Figure 2 The cleaning component 430 also includes: a water tank 435, which is arranged on the photovoltaic bracket 100; a water pump 436, which is connected to the water tank 435; a transmission pipe 437, which connects the spray part 431 and the water pump 436, and the water pump 436 is used to extract the cleaning liquid in the water tank 435 and transport it to the spray chamber 432 through the transmission pipe 437.

[0077] In this embodiment, the water tank 435 is filled with cleaning liquid, and the water pump 436 can extract the cleaning liquid in the water tank 435 and transport it to the spray chamber 432 of the spray part 431 through the transmission pipe 437, so that the bristles 434 can brush the photovoltaic panel 200.

[0078] It should be noted that the cleaning liquid can be water, a chemical cleaning agent, or a mixture of water and a chemical cleaning agent, etc., and the present invention does not limit them.

[0079] Further, see Figure 2 The water tank 435 is arranged at the bottom of the photovoltaic bracket 100, which can lower the center of gravity of the entire photovoltaic power generation device.

[0080] In the present invention, the photovoltaic panel 200 includes a panel body (not shown) and a power generation unit (not shown). The panel body is arranged on the photovoltaic bracket 100, and the photovoltaic bracket 100 can support the panel body. The power generation unit is arranged on the panel body, and the panel body can support the power generation unit.

[0082] Specifically, the side of the plate body has a slide groove (not shown), and the first drive motor 310, the screw rod 320 and the slider 330 are all arranged in the slide groove. The first drive motor 310 is connected to the groove wall of the slide groove by welding, screwing or riveting. One end of the screw rod 320 is connected to the output end of the first drive motor 310, and the other end of the screw rod 320 can be connected to the groove wall of the slide groove through a bearing. The slider 330 can move along the screw rod 320 in the slide groove.

[0083] Furthermore, a slide rod (not shown) can be provided in the slide groove, and the slide rod is parallel to and spaced apart from the screw rod 320 . The slider 330 is simultaneously mounted on the slide rod and the screw rod 320 , so that the movement of the slider 330 is more stable.

[0084] The position and altitude of the sun are constantly changing during the process of rising and setting. If the orientation of the photovoltaic panel 200 is relatively fixed, the utilization rate of solar energy by the photovoltaic panel 200 will be low.

[0085] In view of the above technical problems, in some embodiments, see Figure 2 The photovoltaic bracket 100 includes a base 110 and a support rod 120 arranged on the base 110. The support rod 120 is rotatably connected to the photovoltaic panel 200 to adjust the inclination angle of the photovoltaic panel 200 relative to the support rod 120.

[0086] In this embodiment, the inclination angle of the photovoltaic panel 200 relative to the support rod 120 is adjustable, so that the orientation of the photovoltaic panel 200 can adapt to the change in the height of the sun, so that it can maximize the use of solar energy to increase its power generation.

[0087] In other embodiments, see Figure 2The photovoltaic power generation device also includes a second drive motor 600, which is arranged on the base 110. The output end of the second drive motor 600 is connected to the support rod 120, and the second drive motor 600 can drive the support rod 120 to rotate along the center line of the support rod 120.

[0088] In this embodiment, the second drive motor 600 can drive the support rod 120 to rotate along the center line of the support rod 120, so that the photovoltaic panel 200 can rotate along the center line of the support rod 120, so that the orientation of the photovoltaic panel 200 can adapt to the changes in the position of the sun, so that it can maximize the use of solar energy to increase its power generation.

[0089] See Figure 2 The photovoltaic power generation device also includes a controller 500, which is arranged on the photovoltaic bracket 100 or the photovoltaic panel 200. The controller 500 stores data on changes in the sun's position during the day. The controller 500 can control the operation of the second drive motor 600 based on this data so that the orientation of the photovoltaic panel 200 can adapt to changes in the sun's position.

[0090] In some specific embodiments, a third drive motor (not shown) is provided on the support rod 120, and a connecting portion (not shown) is provided on the photovoltaic panel 200. The driving end of the third drive motor is connected to the connecting portion, and the third drive motor can drive the connecting portion to rotate to adjust the inclination angle of the photovoltaic panel 200 relative to the support rod 120.

[0091] Furthermore, the support rod 120 has a groove (not shown), the connecting part of the photovoltaic panel 200 is inserted in the groove, and the connecting part has a rotating shaft (not shown), the two ends of the rotating shaft are rotatably connected to the two side walls of the groove through bearings, and the driving end of the third drive motor is connected to the rotating shaft. The third drive motor can drive the rotating shaft to rotate to adjust the inclination angle of the photovoltaic panel 200 relative to the support rod 120.

[0092] In this embodiment, the support rod 120 can directly support the photovoltaic panel 200, and the operation of the photovoltaic panel 200 is more stable.

[0093] Furthermore, the controller 500 stores data on changes in the sun's altitude during a day. The controller 500 can control the operation of the third drive motor based on this data so that the orientation of the photovoltaic panel 200 can adapt to changes in the sun's altitude.
