[0002] Photovoltaic modules generally refer to solar cell modules. Since the output voltage of a single solar cell is low and the electrodes of unpackaged cells are easily detached due to environmental influences, a certain number of single cells must be sealed into solar cell modules in series and parallel to avoid corrosion of the cell electrodes and interconnects. In addition, packaging also prevents cell breakage and facilitates outdoor installation. The quality of packaging determines the service life and reliability of solar cell modules.

[0003] At present, when cleaning photovoltaic modules, workers mostly use manual cleaning to clean photovoltaic modules.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0021] When cleaning traditional photovoltaic modules, workers use manual methods to clean the modules. Since most photovoltaic modules are installed at high places, workers need to come to the front of the photovoltaic modules to clean them. After cleaning, the photovoltaic modules will need to be cleaned again due to factors such as rain and snow. This results in multiple times of time and cost to clean the photovoltaic modules. In addition, every time the photovoltaic modules are cleaned manually, there is also the risk of high-altitude operations because the photovoltaic modules are installed at high places.

[0022] In view of this, the utility model provides a photovoltaic module that can automatically clean its surface. The photovoltaic module that can automatically clean its surface solves the problem that traditional manual cleaning requires multiple visits to the photovoltaic module, which wastes time and cost, through a lifting device, a transmission device and a cleaning device. The present invention can realize automatic cleaning of the surface of the photovoltaic module through the cooperation of a lifting device, a transmission device and a cleaning device. The intervention of staff is not required, thereby reducing the work intensity of staff and eliminating the risk of manual high-altitude operations.

[0023] Embodiment 1: Figure 1 , 2 , 3 and 4 show that a photovoltaic assembly capable of automatically cleaning the surface comprises a bottom plate 1, two supporting plates 2 are arranged above the bottom plate 1, photovoltaic panels 3 are arranged below the two supporting plates 2, a collecting box 4 is installed above the bottom plate 1, and the photovoltaic assembly capable of automatically cleaning the surface further comprises: a lifting device 5 installed above the bottom plate 1; a transmission device 6 arranged above the bottom plate 1; a cleaning device 7 arranged below the supporting plates 2; a water level detection device 8 arranged above the bottom plate 1; wherein the lifting device 5 can adjust the height during cleaning, the transmission device 6 changes the cleaning position, the cleaning device 7 can clean the photovoltaic, and the water level detection device 8 can control the amount of rainwater falling into;

[0024] In the specific implementation process, it is worth pointing out that the bottom plate 1 plays a role in holding the whole device, the support plate 2 can protect the transmission device 6, the collection box 4 can collect and store rainwater on rainy days, and water can be directly added to the collection box 4. The lifting device 5, the transmission device 6 and the cleaning device 7 are used together to clean the photovoltaic components;

[0025] Specifically, when using the photovoltaic module that can automatically clean the surface, the staff first adds water to the inside of the collection box 4, and the water level detection device 8 will detect the water level. When the water level reaches the specified position, the water inlet of the collection box 4 will be blocked. At this time, the staff starts to clean the photovoltaic module by starting the cleaning device 7. The photovoltaic modules at different positions can be cleaned through the transmission device 6. The height of the cleaning device 7 can be adjusted according to the inclination of the photovoltaic panel through the lifting device 5, so as to clean each position of the photovoltaic module and complete the cleaning operation of the surface of the photovoltaic module.

[0026] Embodiment 2: By Figure 1 and 2 It can be seen that the lifting device 5 includes: four vertical tubes 501, which are respectively installed above the bottom plate 1; four vertical rods 502, which are respectively installed below the two support plates 2 and are respectively plugged into the inner walls of the four vertical tubes 501; four electric push rods 503, which are respectively arranged inside the four vertical tubes 501 and are respectively fixedly connected to the bottoms of the four vertical rods 502; wherein the electric push rods 503 drive the vertical rods 502 to move along the inner walls of the vertical tubes 501, thereby driving the support plates 2 to move;

[0027] In the specific implementation process, it is worth pointing out that the vertical tube 501 and the vertical rod 502 support the transmission device 6, the vertical rod 502 can move along the inner wall of the vertical tube 501, and the four electric push rods 503 are all provided with an external power supply. The four electric push rods 503 can be controlled simultaneously by an external power supply to perform length adjustment operations;

[0028] Specifically, on the basis of the above-mentioned embodiment 1, the staff starts the electric push rod 503 through an external power supply. The model of the electric push rod 503 is TG-700. After the electric push rod 503 is energized, the output end drives the vertical rod 502 to move. The vertical rod 502 begins to move on the inner wall of the vertical tube 501 under the force. The electric push rod 503 adjusts its own length according to the height of the photovoltaic component to be cleaned. When the photovoltaic component to be cleaned is at a higher position, the electric push rod 503 begins to extend. When the photovoltaic component to be cleaned is at a lower position, the electric push rod 503 begins to retract. At the same time, in conjunction with the transmission device 6 and the cleaning device 7, the surface of the photovoltaic components in various parts can be automatically cleaned.

[0029] Embodiment 3: By Figure 1 , 2As can be seen from Figures 4, the transmission device 6 includes: a first servo motor 601, the model of the first servo motor 601 is ECMA-E1 1320RS, two of which are provided and respectively installed on the outer walls of the two support plates 2; two threaded rods 602 are provided and respectively installed on the output ends of the two first servo motors 601 and respectively provided inside the two support plates 2; two connecting blocks 603 are provided and respectively threadedly connected to the outer walls of the two threaded rods 602 and respectively installed inside the two support plates 2; two sliders 604 are provided and respectively provided below the two connecting blocks 603; two slide rails 605 are provided and respectively fixedly connected to the bottoms of the two support plates 2 and slidably engaged with the outer walls of the two sliders 604; wherein the first servo motor 601 drives the threaded rod 602 to drive the slider 604 to slide along the outer wall of the slide rail 605 through the connecting block 603, and can be automatically cleaned in cooperation with the cleaning device 7;

[0030] In the specific implementation process, it is worth pointing out that the two first servo motors 601 are both provided with an external power supply, and the two first servo motors 601 can be started and shut down simultaneously by the external power supply. When the threaded rod 602 is subjected to force, it can rotate inside the support plate 2 through the bearing. When the connecting block 603 and the slider 604 are subjected to force, they will move in the same direction. The slide rail 605 limits the movement path of the slider 604 to avoid deviation during movement.

[0031] Specifically, on the basis of the above-mentioned embodiment 1, the staff first turns on the first servo motor 601 through an external power supply. After the first servo motor 601 is powered on, it starts to drive the threaded rod 602 to rotate, and the connecting block 603 threadedly connected to the threaded rod 602 is forced to start moving on the outer wall of the threaded rod 602. At the same time, the connecting block 603 drives the slider 604 to move. At this time, the slider 604 is forced to slide along the outer wall of the slide rail 605. The first servo motor 601 changes the rotation direction according to the position to be cleaned. When cleaning a photovoltaic component at a lower position, the first servo motor 601 rotates to drive the slider 604 to approach this position. When cleaning a photovoltaic component at a higher position, the first servo motor 601 rotates in the opposite direction to drive the slider 604 to approach the new position. The photovoltaic component can be cleaned in conjunction with the lifting device 5 and the cleaning device 7.

[0032] Embodiment 4: By Figure 1 and 2 It can be seen that the cleaning device 7 includes: a water pump 701, the model of the water pump 701 is 50WQD10-10-0.75, installed on the inner wall of the collection box 4; a hose 702, connected to the output end of the water pump 701; a cleaning head 703, connected to the hose 702, and fixedly connected to the bottom of the slider 604; wherein the water pump 701 delivers water to the cleaning head 703 through the hose 702;

[0033] In the specific implementation process, it is worth pointing out that the water pump 701 is provided with an external power supply, and the start and stop of the water pump 701 can be controlled by the external power supply. When the transmission device 6 drives the cleaning head 703 to perform the cleaning operation, the hose 702 can change its position with the movement of the transmission device 6;

[0034] Specifically, based on the above-mentioned embodiment 1, the staff first turns on the water pump 701 through an external power supply. After the water pump 701 is powered on, the internal water of the collection box 4 will be discharged into the inside of the hose 702. As the water discharged into the hose 702 gradually increases, the water inside the hose 702 will flow into the inside of the cleaning head 703 after it is filled. The water inside the cleaning head 703 flows onto the brush through the groove. At this time, the brush wetted by water can clean the photovoltaic module, and cooperate with the lifting device 5 and the transmission device 6 to complete the photovoltaic module cleaning operation.

[0035] Embodiment 5: By Figure 1 , 2 As can be seen from Figure 3, the water level detection device 8 includes: a controller 801, the model of the controller 801 is not specifically limited, and it can meet the use requirements and be installed above the collection box 4; a water level detector 802, the model of the water level detector 802 is not specifically limited, and it can meet the use requirements, and two are set, and both are installed inside the collection box 4; a second servo motor 803, the model of the second servo motor 803 is not specifically limited, and it can meet the use requirements and be installed above the collection box 4; a baffle 804, which is set on the outer wall of the output end of the second servo motor 803 and fits with the inner wall of the collection box 4; wherein the water level detector 802 feeds back the detection result to the controller 801, and the second servo motor 803 can drive the baffle 804 to rotate;

[0036] In the specific implementation process, it is worth pointing out that the controller 801 can receive the information fed back by the water level detector 802, and control the start and stop of the second servo motor 803 at the same time. The two water level detectors 802 are responsible for the signal feedback of full water and water shortage respectively. The water level detector 802 near the opening of the collection box 4 is responsible for the full water signal feedback, and the water level detector 802 far from the opening of the collection box 4 is responsible for the water shortage signal feedback. The rotation direction of the second servo motor 803 can control the movement direction of the baffle 804.

[0037] Specifically, on the basis of the above-mentioned embodiment 1, on rainy days, rainwater will fall into the collection box 4 and be stored. When the water level of rainwater rises to the water level detector 802 close to the opening of the collection box 4, the water level detector 802 will feed back the detection result to the controller 801. At this time, the controller 801 will control the second servo motor 803 to rotate, and the second servo motor 803 drives the baffle 804 to block the opening of the collection box 4, so that rainwater cannot fall into the collection box 4. When the remaining amount of stored water is lower than the water level detector 802 far away from the opening of the collection box 4, the water level detector 802 feeds back the new detection result to the controller 801, and the controller 801 will control the second servo motor 803 to rotate in the opposite direction, and the second servo motor 803 drives the baffle 804 to leave the opening of the collection box 4. At this time, rainwater can fall into the collection box 4.
