Description

TECHNICAL FIELD

[0001] The utility model relates to photovoltaic module cleaning equipment technical field, specifically a kind of hand-held cleaning photovoltaic module equipment. BACKGROUND

[0002] Photovoltaic module, also known as solar panel, is the core equipment for converting solar energy into electrical energy, mainly composed of solar cells, glass cover plate, EVA film, back plate, aluminum alloy frame and junction box. The use scenario of photovoltaic module is outdoor, and the dust, dirt and other impurities on its surface will affect the power generation efficiency after long outdoor use, so it needs to be cleaned regularly.

[0003] The commonly used cleaning equipment is a hand-held cleaning device, which is composed of a base plate, a brushing roller, a water tank, a water delivery pipe and other components. The brushing roller is driven to roll by the pressure of water to improve the cleaning effect. The design of the roller can prevent the base plate from pressing too hard on the photovoltaic module, causing damage. The combined length of the sleeve and the movable rod can also be adjusted to meet different cleaning needs.

[0004] Since photovoltaic modules are used outdoors, the outdoor environment is complex, and the surface of the photovoltaic module not only has dust and impurities, but also has stubborn impurities such as bird droppings. It is difficult to efficiently remove the bird droppings on the photovoltaic module with the brushing rod of the hand-held cleaning device, resulting in residual bird droppings on the photovoltaic module. The residual bird droppings will block part of the photovoltaic module, and the current and voltage generated by the blocked part and the unblocked part under light will be different, causing local resistance difference. According to Joule's law, the resistance difference will cause more heat to be generated at the part blocked by bird droppings, forming a hot spot, which will cause the photovoltaic module to age and degrade in performance. Therefore, a hand-held cleaning photovoltaic module device is proposed to solve the above problems. SUMMARY

[0005] In order to make up for the shortcomings of the prior art and solve at least one technical problem raised in the background art, the utility model provides a hand-held cleaning photovoltaic module device.

[0006] The utility model solves the technical problems by adopting the following technical scheme: the utility model discloses a kind of hand-held cleaning photovoltaic module devices, including hand-held cleaning device, rectangular frame is fixedly installed on the hand-held cleaning device, electric push rod and storage box are fixedly installed in the rectangular frame, the output end of the electric push rod is fixedly installed with connecting rod, and the one end of the connecting rod is in the storage box. Push plate is arranged in the storage box, a sealing ring is fixedly installed on the surface of the push plate, the push plate is sealed sliding in the storage box by the sealing ring, the connecting rod and the push plate are connected, and the one side of the rectangular frame is fixedly installed with the liquid outlet pipe that is connected with the inside of the storage box.

[0007] Further, the liquid outlet pipe is fixedly installed with a U-shaped flow guide pipe at one end away from the storage box, the flow guide pipe is fixedly installed with a filter screen at one end away from the liquid outlet pipe, and one side of the filter screen is fixedly installed with two symmetrically arranged arc-shaped guide plates.

[0008] Further, the connecting rod and the push plate are sealingly and slidably connected, a first cavity is formed in the push plate, a first electromagnet is fixedly installed in the first cavity, a second cavity is formed in the surface of the connecting rod, and a second electromagnet is fixedly installed in the second cavity.

[0009] Further, the bottom of the connecting rod is rotatably connected with a plurality of symmetrically arranged fan blades, the fan blades are made of lightweight material and are below the push plate.

[0010] Further, the surface of the storage box is sleeved with a heating wire.

[0011] Further, the rectangular frame is fixedly installed with two symmetrically arranged hollow fixed frames, the output end of the electric push rod is fixedly installed with two symmetrically arranged fixed rods, one end of the fixed rod is in the fixed frame, the end of the fixed rod is fixedly installed with a sealing plate and sealingly and slidably connected with the fixed frame, and one side of the fixed frame is fixedly installed with a plurality of gas outlet pipes in communication with the inside.

[0012] The utility model has the advantages that:

[0013] 1. The utility model discloses a handheld cleaning device, which comprises a storage box, a rectangular frame, an electric push rod, a connecting rod, a push plate, a sealing ring, a liquid outlet pipe, a flow guide pipe, a filter screen and guide plates.

[0014] 2. This invention de-energizes the first and second electromagnets while simultaneously activating the heating wire within the rectangular frame. This generates heat, which in turn heats the cleaning agent. Appropriate heating enhances the activity of the chemicals in the cleaning agent, allowing it to better react with the dirt on the photovoltaic module surface after subsequent spraying, accelerating the decomposition and removal of the dirt. Activating the electric push rod within the rectangular frame allows its output end, along with the connecting rod, to slide into the storage box. As the connecting rod moves, it also moves the fan blades, which rotate upon contact with the liquid, agitating the cleaning agent and ensuring it is fully mixed again, effectively preventing sedimentation after prolonged standing. As the electric push rod's output end moves downward, it slides and compresses the fixing rod and sealing plate into the fixing frame, forcing the gas within the fixing frame through the exhaust pipe towards the heating wire. This directs the heat emitted by the heating wire towards the storage box, assisting in efficient preheating and accelerating the preheating process. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figures 1-7 As shown, a handheld photovoltaic module cleaning device includes a handheld cleaner 1. A rectangular frame 2 is fixedly installed on the handheld cleaner 1. An electric push rod 3 and a storage box 5 are fixedly installed inside the rectangular frame 2. A connecting rod 4 is fixedly installed at the output end of the electric push rod 3, and one end of the connecting rod 4 is inside the storage box 5. A push plate 6 is provided inside the storage box 5. A sealing ring 7 is fixedly installed on the surface of the push plate 6. The push plate 6 slides in a sealed manner inside the storage box 5 through the sealing ring 7. The connecting rod 4 is connected to the push plate 6. A liquid outlet pipe 8, which communicates with the inside of the storage box 5, is fixedly installed on one side of the rectangular frame 2. A U-shaped guide pipe 9 is fixedly installed at the end of the liquid outlet pipe 8 away from the storage box 5. A filter screen 10 is fixedly installed at the end of the guide pipe 9 away from the liquid outlet pipe 8. Two symmetrically arranged, arc-shaped guide plates 11 are fixedly installed on one side of the filter screen 10.

[0026] Before using the handheld cleaner 1, pre-fill the storage box 5 with cleaning agent through the inlet pipe (not shown in the figure, and the inlet pipe has a built-in one-way valve). When the handheld cleaner 1 is used, activate the electric push rod 3 (miniature version) inside the rectangular frame 2. The electric push rod 3 slides downwards through the connecting rod 4, along with the push plate 6 and sealing ring 7, thereby squeezing the pre-stored cleaning agent inside the storage box 5. This causes the cleaning agent to enter the guide tube through the outlet pipe 8 (with a built-in one-way valve), where it is diverted. Finally, the cleaning agent is sprayed out through the arc-shaped guide plate 11 inside the guide tube. The guide plate 11 guides the cleaning agent to both sides, preventing it from spraying only directly in front of the guide tube. This allows the cleaning agent to be sprayed in front of the handheld cleaner 1, making it easier to wet the brush roller at the bottom of the handheld cleaner 1 for cleaning. The installed filter screen 10 reduces the entry of impurities into the guide tube when it is not in use, ensuring its unobstructed flow.

[0027] The structure designed above allows the cleaning agent to be sprayed quickly onto the surface of the photovoltaic module, thereby quickly removing bird droppings and other impurities from the surface of the photovoltaic module. This solves the problem of traditional handheld cleaners not being able to clean the module properly and avoids the hot spot effect caused by residual bird droppings.

[0028] The connecting rod 4 and the push plate 6 are connected in a sealed sliding connection. The push plate 6 has a first cavity 12 inside, and a first electromagnet 13 is fixedly installed inside the first cavity 12. The surface of the connecting rod 4 has a second cavity 14, and a second electromagnet 15 is fixedly installed inside the second cavity 14. Several symmetrically arranged fan blades 16 are rotatably connected to the bottom of the connecting rod 4. The fan blades 16 are made of lightweight material and are located below the push plate 6.

[0029] Specifically, a heating wire 17 is fitted onto the surface of the storage box 5. Two symmetrically arranged hollow fixed frames 19 are fixedly installed inside the rectangular frame 2. Two symmetrically arranged fixed rods 18 are fixedly installed at the output end of the electric push rod 3. One end of the fixed rod 18 is located inside the fixed frame 19. A sealing plate 20 is fixedly installed at one end of the fixed rod 18 and is slidably connected to the fixed frame 19. Several air outlet pipes 21 that communicate with the interior are fixedly installed on one side of the fixed frame 19.

[0030] During operation, when the connecting rod 4 moves downwards with the push plate 6, the first electromagnet 13 in the first cavity 12 and the second electromagnet 15 in the second cavity 14 are energized, causing opposite poles to attract each other, thus moving the connecting rod 4 and the push plate 6. When the cleaning agent stored in the storage box 5 has been left unused for a long time, before use, the first electromagnet 13 and the second electromagnet 15 are de-energized, and the heating wire 17 in the rectangular frame 2 is activated, generating heat to assist in heating the cleaning agent. Appropriate heating can enhance the activity of the chemicals in the cleaning agent, allowing it to better react with the dirt on the photovoltaic module surface after subsequent spraying, accelerating the decomposition and removal of the dirt. The electric push rod 3 in the rectangular frame 2 is activated, causing its output end to slide into the storage box 5 along with the connecting rod 4. As the connecting rod 4 moves, it also moves the fan blade 16, which rotates upon contact with the liquid, agitating the cleaning agent and ensuring it is fully mixed again, effectively preventing sedimentation after prolonged standing. When the output end of the electric push rod 3 moves down, it will slide and squeeze the fixed rod 18 and the sealing plate 20 into the fixed frame 19, thereby blowing the gas in the fixed frame 19 through the air outlet pipe 21 to the heating wire 17, and blowing the hot air emitted by the heating wire 17 to the storage box 5, assisting the storage box 5 to perform efficient preheating, thereby accelerating the preheating efficiency.

[0031] Working principle: Before using the handheld cleaner 1, cleaning agent is pre-filled into the storage box 5 through the inlet pipe. When the handheld cleaner 1 is used, the electric push rod 3 inside the rectangular frame 2 is activated, causing the electric push rod 3 to slide downwards along the push plate 6 and sealing ring 7 via the connecting rod 4. This squeezes the pre-stored cleaning agent inside the storage box 5, allowing the cleaning agent to enter the guide tube through the outlet pipe 8. The agent is then diverted within the guide tube and finally sprayed out through the arc-shaped guide plate 11 inside the guide tube. The guide plate 11 directs the cleaning agent to both sides, preventing it from spraying only directly in front of the guide tube. This ensures the cleaning agent is sprayed in front of the handheld cleaner 1, facilitating the wetting of the brush roller at the bottom of the handheld cleaner 1 for cleaning. Simultaneously, the installed filter screen 10 reduces the entry of impurities into the guide tube when not in use, ensuring its unobstructed flow.

[0032] When the connecting rod 4 moves down with the push plate 6, the first electromagnet 13 in the first cavity 12 and the second electromagnet 15 in the second cavity 14 are energized, causing opposite poles to attract each other, thus moving the connecting rod 4 and the push plate 6. When the cleaning agent stored in the storage box 5 has been left unused for a long time, before use, the first electromagnet 13 and the second electromagnet 15 are de-energized, and the heating wire 17 in the rectangular frame 2 is activated, generating heat to assist in heating the cleaning agent. The electric push rod 3 in the rectangular frame 2 is activated, causing its output end to slide into the storage box 5 along with the connecting rod 4. As the connecting rod 4 moves, it also moves the fan blade 16, which rotates upon contact with the liquid, thus agitating the cleaning agent. When the output end of the electric push rod 3 moves down, it will slide and squeeze the fixed rod 18 and the sealing plate 20 into the fixed frame 19, thereby blowing the gas in the fixed frame 19 through the air outlet pipe 21 to the heating wire 17, and blowing the heat emitted by the heating wire 17 to the storage box 5 in a better way.
