Description

Technical Field

[0001] The present invention relates to the field of photovoltaic cleaning equipment, and more specifically, to a photovoltaic panel cleaning equipment for photovoltaic power generation with a protection structure. Background Art

[0002] In the field of photovoltaic power generation, photovoltaic panel cleaning equipment plays a crucial role in maintaining the high-efficiency power generation performance of photovoltaic panels. With the continuous growth of the global demand for clean energy, the scale of photovoltaic power generation is expanding day by day. As the core component, the cleanliness of the surface of photovoltaic panels directly affects the power generation efficiency. The photovoltaic panel cleaning equipment for photovoltaic power generation with a protection structure aims to, through specific mechanical structures and cleaning methods, remove impurities such as dust and dirt on the surface of photovoltaic panels while avoiding damage to the photovoltaic panels, ensuring that the photovoltaic panels are always in good working condition, and thus improving the overall efficiency of the photovoltaic power generation system. This equipment is widely used in various photovoltaic power stations. Whether it is a large-scale centralized power station or a distributed small-scale power station, there is an urgent need for its cleaning and protection functions.

[0003] However, traditional photovoltaic panel cleaning equipment has many deficiencies. In terms of cleaning effect, most traditional equipment cannot make full use of natural water sources, relying solely on manual labor or simple spraying devices, resulting in low cleaning efficiency and difficulty in thoroughly removing stubborn stains on the surface of photovoltaic panels, thus limited improvement in the power generation efficiency of photovoltaic panels. During the cleaning process, traditional equipment lacks an effective cleaning and maintenance mechanism for cleaning tools. Dust is easily attached to the surface of cleaning tools. During repeated cleaning, not only does the cleaning effect of the tools themselves decrease significantly, but they are also likely to scratch the surface of photovoltaic panels, affecting the service life and power generation performance of photovoltaic panels. In addition, the drainage design of traditional cleaning equipment is unreasonable, and it is prone to poor drainage. Water accumulates on the surface of photovoltaic panels or inside the equipment, which may cause equipment failures or exacerbate the corrosion of photovoltaic panels. Moreover, traditional equipment does not have the function of monitoring the operating state of the equipment and self-adjusting, and cannot optimize the cleaning process according to the actual situation, making it difficult to adapt to the diverse needs of different environments and photovoltaic panels. These problems seriously restrict the application effect of traditional photovoltaic panel cleaning equipment and urgently need to be solved through innovative designs. Summary of the Invention

One end surface of the connecting frame close to the installation frame is fixedly connected with a sealing strip, and the upper surface of the sealing strip is fixedly connected to the lower surface of the installation frame.

[0006] Preferably, a first sliding groove is formed in the inner surface of the side plate. One end of the first sliding groove close to the connecting frame is inclined. A cleaning reel is slidably connected in the first sliding groove. Initially, the cleaning reel is arranged inside the connecting frame. Leakage grooves are formed through the bottom of both sides of the connecting frame, and the leakage grooves are strip-shaped.

[0007] Preferably, at the top surface of one end of the side plate away from the connecting frame, an upper driving rod is rotatably connected through a connecting rod. The end of the upper driving rod is rotatably connected with a waterproof motor. The waterproof motor is fixedly connected to the side surface of the side plate on the side away from the connecting frame. A lower driving rod is arranged below the upper driving rod. Both ends of the lower driving rod are rotatably connected to the bottom of the side plate away from the connecting frame through connecting rods. Transmission belts are rotatably connected to the outer surfaces of both ends of the upper driving rod and the lower driving rod.

[0008] Preferably, the cleaning reel includes a connecting shaft. Sliding rings are rotatably sleeved on the outer surfaces of both ends of the connecting shaft. The sliding rings are slidably connected in the first sliding groove. Elastic strips are fixedly connected to the outer surface of the connecting shaft. Cleaning strips are also fixedly connected to the outer surface of the connecting shaft. Four elastic strips are arranged at fixed intervals along the central axis of the connecting shaft. The cleaning strips are arranged between adjacent connecting shafts.

[0009] Preferably, a first pulling rope is fixedly connected to the outer surface of the sliding ring. One end of the first pulling rope away from the sliding ring is wound around the outer surfaces of both ends of the upper driving rod. A second pulling rope is fixedly connected to the outer surface of the sliding ring on the side away from the first pulling rope. One end of the second pulling rope away from the sliding ring is wound around the outer surfaces of both ends of the lower driving rod. The second pulling rope is flat and is arranged directly above the leakage groove.

[0010] Preferably, a second sliding groove is formed inside the first sliding groove. Both ends of the connecting shaft are slidably arranged in the second sliding groove. Rubber strips are fixedly inlaid at the top of the second sliding groove. Rubber rings are fixedly sleeved on both ends of the connecting shaft.

[0011] Preferably, the strengthening mechanism includes an installation groove, which is formed directly outside the leakage groove of the side plate. A rotating belt is rotatably connected in the installation groove. A wave strip is fixedly inlaid on the inner surface of the rotating belt. The wave strip is arranged in the leakage groove, and the upper surface of the wave strip is pressed and fitted against the bottom surface of the second pulling rope.

[0012] Preferably, a guiding frame is fixedly connected to the bottom surface of the connecting frame. The upper surfaces on both sides of the guiding frame are inclined. Vibration plates are symmetrically and fixedly inlaid on both sides of the guiding frame. The vibration plates are made of rubber material.

[0013] Preferably, a rotating rod is arranged below the middle of the guiding frame. The two ends of the rotating rod are respectively rotatably connected to the inner surfaces of the connecting frame and the sealing strip. A supporting rod is fixedly connected to one end of the rotating rod close to the sealing strip. A gear box is rotatably connected to the outer surface of the middle part of the lower driving rod.

The device can be normally used after being installed horizontally outdoors, and power is generated by the photovoltaic panel on the installation frame. When encountering heavy rain, the amount of water entering the connecting frame is much larger than the amount flowing out through the water leakage groove, that is, rainwater will accumulate in the connecting frame. At this time, the waterproof motor can be started. The driving of the waterproof motor drives the upper driving rod to start rotating, and then starts to wind up the first pulling rope. As the first pulling rope is wound up, it drives the cleaning drum to slide along the first chute, so that the cleaning drum gradually moves from the inside of the connecting frame to the surface of the photovoltaic panel to clean the photovoltaic panel. After the cleaning drum moves to the edge of the photovoltaic panel, the waterproof motor is driven in reverse, and then the second pulling rope is pulled to wind up, so that the first pulling rope is released, and then the cleaning drum is pulled back into the connecting frame. This process is repeated to realize the cleaning of the photovoltaic panel.

[0014] Beneficial effects: The present invention provides a cleaning device for a photovoltaic panel used in photovoltaic power generation with a protection structure, having the following beneficial effects: (1). For the cleaning device for a photovoltaic panel used in photovoltaic power generation with a protection structure, the side plates and the connecting frame are higher than the photovoltaic panel. Therefore, when the connecting frame is filled with water, the water will flow along the upper surface of the photovoltaic panel, and the cleaning effect on the photovoltaic panel is further improved in cooperation with the circulating and moving cleaning drum. At the same time, by using the concave design of the connecting frame, when the cleaning drum reciprocates and moves into the connecting frame, the cleaning drum is soaked and cleaned by the water in the connecting frame, so that the dust on the surface of the cleaning drum sinks into the cleaning frame and is discharged outwards through the water leakage groove. At the same time, combined with the water flowing on the photovoltaic panel, the cleaning drum is in a clean state to a great extent when cleaning the photovoltaic panel, thereby protecting the surface of the photovoltaic panel and avoiding the problem that the photovoltaic panel is easily scratched by conventional cleaning devices.

[0015] (ii) The photovoltaic panel cleaning device for photovoltaic power generation with a protective structure, as the cleaning drum moves, the No. 2 pull rope will move back and forth continuously, and then the rotating belt in the mounting groove on the side plate will start to rotate through the extrusion and friction effect, and then the waving bar will move back and forth in the water leakage groove, so as to dredge the water leakage groove, and avoid the problem that the water leakage groove is blocked due to excessive dust, so that the water in the connecting frame cannot be discharged and deteriorates and pollutes the cleaning drum. In the process of moving the cleaning drum, the support rod will start to rotate through the joint action of the lower driving rod and the gear box, and then drive the rotating rod to start rotating, so that the extrusion strip connected to the outer surface of the rotating rod through the elastic telescopic plate starts to make a circular rotation around the rotating rod, so that the extrusion strip intermittently hits the vibration plate and squeezes it, so that the vibration plate intermittently vibrates when the device is working, and then helps to guide the dust at the bottom of the connecting frame, so that the dust is close to the leakage groove, thereby facilitating the discharge of dust and further reducing the risk of the leakage groove being blocked.

[0016] (III) In the photovoltaic panel cleaning device with a protective structure for photovoltaic power generation, the cleaning reel is actually moved by pulling the sliding ring through the No. 1 pull rope and the No. 2 pull rope, thereby driving the connecting shaft to move synchronously, and then the rubber rings at both ends of the connecting shaft slide in the No. 2 slide groove. When the cleaning reel moves to the surface of the photovoltaic panel, it means that the rubber ring and the rubber strip come into contact, and the friction force causes the connecting shaft and the sliding rings on both sides of it to rotate relative to each other, thereby realizing that the cleaning strip on its outer surface and the elastic strip rotate synchronously through the rotation of the connecting shaft during the movement of the cleaning reel, thereby realizing that the cleaning reel is moved by the rotation of the connecting shaft. When the cleaning strip cleans the surface of the photovoltaic panel, the contact surface between the cleaning strip and the photovoltaic panel is rolled and cleaned in real time by the rotation of the cleaning strip, so as to avoid the accumulation of dust at the contact place between the cleaning strip and the photovoltaic panel, which may cause the photovoltaic panel to be scratched. At the same time, as the connecting shaft rotates, the elastic strip will intermittently contact and squeeze the upper surface of the photovoltaic panel, causing the elastic strip to deform. As the connecting shaft continues to rotate, the elastic strip that has been squeezed and deformed will be out of contact with the photovoltaic panel and will be instantly reset, generating an elastic force to help further eject the dust, thereby further improving the dust handling capability and the protection capability of the photovoltaic panel.

One end of the first pull rope 315 far from the sliding ring 312 is wound around the outer surfaces of both ends of the upper driving rod 37. A second pull rope 316 is fixedly connected to the outer surface of the side of the sliding ring 312 far from the first pull rope 315. One end of the second pull rope 316 far from the sliding ring 312 is wound around the outer surfaces of both ends of the lower driving rod 39. Among them, the second pull rope 316 is flat, and the second pull rope 316 is arranged directly above the leakage groove 36.

[0025] A second sliding groove 317 is formed inside the first sliding groove 34. Both ends of the connecting shaft 311 are slidably arranged in the second sliding groove 317. Rubber strips 318 are fixedly inlaid at the top of the second sliding groove 317. Rubber rings 319 are fixedly sleeved on both ends of the connecting shaft 311.

[0026] The third embodiment: As Figures 1 to 8 shown, the strengthening mechanism 4 includes an installation groove 41. The installation groove 41 is formed on the outer side of the leakage groove 36 of the side plate 31. A rotating belt 42 is rotatably connected in the installation groove 41. A wave strip 43 is fixedly inlaid on the inner surface of the rotating belt 42. The wave strip 43 is arranged in the leakage groove 36. The upper surface of the wave strip 43 is pressed and fitted against the bottom surface of the second pull rope 316.

[0027] The bottom surface of the connecting frame 32 is fixedly connected with a guiding frame 44. The upper surfaces on both sides of the guiding frame 44 are inclined. Vibration plates 45 are symmetrically and fixedly embedded on both sides of the guiding frame 44. The vibration plates 45 are made of rubber material.

[0028] A rotating rod 46 is arranged below the middle of the guiding frame 44. The two ends of the rotating rod 46 are respectively rotatably connected to the inner surfaces of the connecting frame 32 and the sealing strip 33. One end of the rotating rod 46 close to the sealing strip 33 is fixedly connected with a support rod 47. The middle outer surface of the lower driving rod 39 is rotatably connected with a gear box 48. The gear box 48 is fixedly connected to the side surface of the installation frame 1. The end of the support rod 47 is rotatably connected to the output end of the gear box 48. An elastic telescopic plate 49 is fixedly connected to the outer surface of the rotating rod 46. An extrusion strip 410 is fixedly connected to the outer end of the elastic telescopic plate 49.

[0029] When in use, this device can be installed horizontally outdoors normally for normal operation, and electricity is generated through the photovoltaic panel 2 on the installation frame 1. When encountering heavy rain, the amount of water entering the connection frame 32 is much larger than the amount flowing out through the water leakage groove 36, that is, rainwater will accumulate in the connection frame 32. At this time, the waterproof motor 38 can be started. Driven by the waterproof motor 38, the upper drive rod 37 starts to rotate, and then the first pull rope 315 starts to be wound. As the first pull rope 315 is wound, the cleaning drum 35 will be driven to slide along the first chute 34, so that the cleaning drum 35 gradually moves from the inside of the connection frame 32 to the surface of the photovoltaic panel 2 to clean the photovoltaic panel 2. After the cleaning drum 35 moves to the edge of the photovoltaic panel 2, the waterproof motor 38 is driven in the reverse direction, and then the second pull rope 316 is pulled to be wound through the lower drive rod 39, so that the first pull rope 315 is released, and then the cleaning drum 35 is pulled back into the connection frame 32. This process is repeated to clean the photovoltaic panel 2. The height of the side plate 31 and the connection frame 32 is higher than that of the photovoltaic panel 2. Therefore, when the water in the connection frame 32 is full, it will flow along the upper surface of the photovoltaic panel 2, cooperating with the circularly moving cleaning drum 35 to further improve the cleaning effect on the photovoltaic panel 2. At the same time, using the concave design of the connection frame 32, when the cleaning drum 35 reciprocally moves into the connection frame 32, the water in the connection frame 32 is used to soak and clean the cleaning drum 35, so that the dust on the surface of the cleaning drum 35 sinks into the cleaning frame and is discharged outward through the water leakage groove 36. Combined with the flowing water on the photovoltaic panel 2, when cleaning the photovoltaic panel 2, the cleaning drum 35 is kept clean to a great extent, thereby protecting the surface of the photovoltaic panel 2 and avoiding the problem that the conventional cleaning equipment is likely to scratch the photovoltaic panel 2. As the cleaning drum 35 moves, the second pull rope 316 will continuously reciprocally move, and then through the extrusion and friction action, the rotating belt 42 in the installation groove 41 on the side plate 31 starts to rotate, and then the wave bar 43 reciprocally moves back and forth in the water leakage groove 36, thereby dredging the water leakage groove 36 and avoiding the problem that the water in the connection frame 32 cannot be discharged and deteriorates to pollute the cleaning drum 35 due to excessive dust blocking the water leakage groove 36. During the movement of the cleaning drum 35, through the combined action of the lower drive rod 39 and the gear box 48, the support rod 47 starts to rotate, and then drives the rotating rod 46 to start rotating, so that the extrusion bar 410 connected to the outer surface of the rotating rod 46 through the elastic telescopic plate 49 starts to rotate around the rotating rod 46 in a circular motion, so that the extrusion bar 410 intermittently impacts and squeezes on the vibration plate 45, so that the vibration plate 45 intermittently generates vibration during the operation of this device, thereby helping to guide the dust at the bottom of the connection frame 32 to approach the water leakage groove 36, facilitating the discharge of the dust, and further reducing the risk of the water leakage groove 36 being blocked. In fact, during the movement of the cleaning drum 35, it is a process of pulling the sliding ring 312 to move through the first pull rope 315 and the second pull rope 316, thereby driving the connecting shaft 311 to move synchronously.Furthermore, the rubber rings 319 at both ends of the connecting shaft 311 slide within the second chute 317. When the cleaning reel 35 moves to the surface of the photovoltaic panel 2, it means that the rubber ring 319 comes into contact with the rubber strip 318. Due to the action of friction, the connecting shaft 311 and the sliding rings 312 on both sides thereof generate relative rotational movement. Furthermore, during the movement of the cleaning reel 35, the cleaning strip 314 on the outer surface of the connecting shaft 311 rotates synchronously with the elastic strip 313 through the rotation of the connecting shaft 311. Thus, when the photovoltaic panel 2 is cleaned by the cleaning strip 314, the contact surface between the cleaning strip 314 and the photovoltaic panel 2 is cleaned by the rotation of the cleaning strip 314 in real time, avoiding the problem that dust accumulates at the place where the cleaning strip 314 contacts the photovoltaic panel 2 and scratches the photovoltaic panel 2. At the same time, as the connecting shaft 311 rotates, the elastic strip 313 intermittently contacts and presses the upper surface of the photovoltaic panel 2, causing the elastic strip 313 to deform. As the connecting shaft 311 continues to rotate, the elastically deformed elastic strip 313 will instantaneously reset when it disengages from the contact with the photovoltaic panel 2, generating an elastic force to help further eject the dust, thereby further improving the dust handling ability and further enhancing the protection ability for the photovoltaic panel 2.
