Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic panel cleaning, in particular to a photovoltaic panel stain and snow cleaning component. Background Art

[0002] Photovoltaic panels are an important component of photovoltaic modules. As an important component of clean energy, the power generation efficiency of photovoltaic power generation is closely related to the cleanliness of the surface of the photovoltaic panels. In actual operation, the surface of photovoltaic panels is prone to accumulate dust, bird droppings and other stains, and is covered with ice and snow in winter. These pollutants will significantly reduce the power generation efficiency of photovoltaic panels. At present, the cleaning of photovoltaic panels mainly relies on manual cleaning or automated cleaning equipment. These methods can maintain the cleanliness of photovoltaic panels to a certain extent.

[0003] However, there are still some problems in actual use: The existing photovoltaic panels are inefficient and have safety hazards when cleaned manually. Ordinary cleaning equipment cannot effectively remove the ice and snow cover in winter and lacks the ability to deep clean stubborn stains. Secondly, most automated cleaning components have a single function and cannot adapt to the cleaning needs of different seasons, resulting in unsatisfactory cleaning effects. When the snow is pushed to one side during cleaning, the snow accumulates on each other and cannot be discharged at any time. As a result, when cleaning to the rear of the photovoltaic panel, a large amount of snow accumulates in the middle, and its weight has a certain impact on the support stability of the photovoltaic panel. In addition, the existing cleaning equipment has high energy consumption and high maintenance costs, and it is difficult to meet the economic requirements of large-scale photovoltaic power stations. These problems seriously affect the operating efficiency and service life of the photovoltaic power generation system. There is an urgent need to develop an efficient, intelligent and adaptable photovoltaic panel cleaning solution. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1-9As shown, the present invention provides a technical solution: a stain and snow cleaning component for photovoltaic panels, comprising a cleaning box 1, a group of upper and lower symmetrical slide rails 2 are provided on both sides of the cleaning box 1, and grooves are provided on the opposite sides of the slide rails 2, the cross-section of the groove is arc-shaped, the opposite sides of the groove are rollingly connected with guide wheels 3, the opposite sides of the guide wheels 3 are movably connected with de-icing mechanisms 4, the front side of the cleaning box 1 is movably connected with an anti-accumulation mechanism 5, and the de-icing mechanism 4 is transmission-connected to the anti-accumulation mechanism 5, the anti-accumulation mechanism 5 is located inside the cleaning box 1, a connecting groove is provided at the bottom of the cleaning box 1, and the anti-accumulation mechanism 5 passes through and extends to the bottom of the cleaning box 1, a accommodating chamber 6 is provided at the rear end of the cleaning box 1, and a stain cleaning mechanism 7 is fixedly connected to the inside of the accommodating chamber 6, and one end of the stain cleaning mechanism 7 passes through the cleaning box 1 and extends to its outside.

[0022] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 9 As shown, the de-icing mechanism 4 includes a drive motor 401, a sprocket 402, a chain 403, a drive shaft 404, a transmission bevel gear 405, a drive bevel gear 406, a transmission rod 407 and a rubber de-icing strip 408. There are two sprockets 402 and they are connected by the chain 403. One of the sprockets 402 is fixedly connected to the output end of the drive motor 401, and the other sprocket 402 is fixedly connected to the outside of the drive shaft 404. There are several transmission bevel gears 405 and they are evenly fixedly connected to the outside of the drive shaft 404.

The driving bevel gears 406 are located directly below the driving bevel gears 405, and the driving bevel gears 406 are meshed with the driving bevel gears 405. The transmission rods 407 are respectively fixedly connected to the driving bevel gears 405. The wheel 406 is away from one end of the meshing transmission bevel gear 405, and the rubber de-icing strip 408 is fixedly connected to the other end of the transmission rod 407 in a circular array. The driving motor 401, sprocket 402 and chain 403 are all located at the outer end of the cleaning box 1, and the driving motor 401 is fixedly connected to the outer end of the cleaning box 1. The driving shaft 404, transmission bevel gear 405, driving bevel gear 406 and transmission rod 407 are all located inside the cleaning box 1. Both ends of the driving shaft 404 pass through the cleaning box 1 and extend outside it. The opposite sides of the guide wheel 3 are respectively fixedly connected to the two ends of the driving shaft 404, and the connection between the driving shaft 404 and the cleaning box 1 is movably connected by a bearing. The outer side of the transmission rod 407 is movably connected to the inside of the cleaning box 1 through a bearing, and the rubber de-icing strip 408 is directly below the cleaning box 1.

[0023] The sprocket 402 is driven by the driving motor 401, and the other sprocket 402 is driven synchronously through the chain 403. At this time, the driving shaft 404 is driven to rotate, and the guide wheel 3 is driven to roll forward on the opposite side of the guide rail. At this time, the cleaning box 1 is slowly pushed forward on the surface of the photovoltaic panel. Secondly, the rotation of the driving shaft 404 synchronously drives several transmission bevel gears 405 to rotate synchronously, prompting the driving bevel gear 406 to drive the rubber de-icing strip 408 through the transmission rod 407 to crush the frozen thin ice on the surface of the photovoltaic panel. In fact, it is separated from the photovoltaic panel, ensuring stable and reliable power transmission and effective crushing of the ice layer without damaging the surface of the photovoltaic panel. Secondly, the driving components are externalized for easy maintenance, and the transmission components are built-in to ensure protection and smooth operation, thereby realizing the synchronization of device movement and de-icing operations, significantly improving the automated de-icing efficiency of photovoltaic power stations in winter, and solving the technical problems of low efficiency and poor safety of traditional manual de-icing.

[0024] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 7 As shown, the anti-accumulation mechanism 5 includes a driving wheel 501, a track 502, a snow pusher 503, a connecting rod 504, a worm gear 505 and a worm 506. The driving wheel 501 is provided with two and is symmetrically arranged. The track 502 is transmission-connected to the outside of the driving wheel 501, the connecting rod 504 is fixedly connected to the axis of the driving wheel 501, and the worm gear 505 is fixedly connected to one of the connecting rods 504 away from the end of the driving wheel 501, and the worm gear 505 is meshed with the worm gear 505. The connecting rod 504 passes through the cleaning box 1 horizontally, and the connection between the connecting rod 504 and the cleaning box 1 is movably connected through a bearing. The driving wheel 501, the track 502 and the snow pusher 503 are all located on the outside of the cleaning box 1, and the worm gear 505 and the worm 506 are all located inside the cleaning box 1. One end of the worm gear 506 passes through the processing tank and is fixedly connected to the axis of the sprocket 402 away from the drive motor 401.

[0025] The sprocket 402 is driven by the driving motor 401 and the worm 506 is driven at the same time. At this time, the worm wheel 505 is driven to drive the driving wheel 501 to rotate through the connecting rod 504, and the track 502 is driven to rotate at the front side of the cleaning box 1. The snow pusher 503 moves along the track of the track 502, thereby moving a large amount of accumulated snow at the front end of the cleaning box 1 to push it to one side of the photovoltaic panel, which is conducive to realizing power diversion and speed conversion, ensuring that the snow pusher 503 runs smoothly and can effectively remove snow from the surface of the photovoltaic panel. Secondly, it breaks the ice layer while removing the snow, significantly improving the automated snow removal efficiency of the photovoltaic power station in winter, and solving the problem that traditional snow removal equipment does not remove snow thoroughly and is prone to secondary accumulation.

[0026] like Figure 1 、 Figure 2 、 Figure 3 and Figure 8 As shown, the stain cleaning mechanism 7 includes a heating coil 701, a heating tube 702, a delivery tube 703, a diversion tube 704, a spray head 705 and an external tube 706. The heating coil 701 is wound around the outside of the heating tube 702, and the external tube 706 is fixedly connected to one end of the heating tube 702. One end of the delivery tube 703 is fixedly connected to the end of the heating tube 702 away from the external tube 706, and the other end of the delivery tube 703 is fixedly connected to one end of the delivery rod. The spray head 705 is provided with several and evenly spaced spray nozzles. It is fixedly connected to the outside of the diverter pipe 704, the heating pipe 702 and the separation pipe are both located inside the accommodating chamber 6, the delivery pipe 703 is located outside the cleaning box 1, the diverter pipe 704 is annular and its two ends respectively pass through the cleaning box 1 and are fixedly connected to the heating pipe 702 and the separation pipe, one end of the external pipe 706 passes through the cleaning box 1 and extends to its outside, the external pipe 706 is located on the outside of the cleaning box 1 and is stretchable, and the end of the spray head 705 away from the diverter pipe 704 passes through the cleaning box 1 and extends to its bottom.

[0027] The external tube 706 is stretched and extended following the movement of the cleaning box 1, and the heating coil 701 is started to heat the cleaning liquid transported from the inside of the external tube 706. The heated cleaning liquid passes through the delivery tube 703 to the diversion tube 704, and is then sprayed out from the spray head 705 to clean and defrost the photovoltaic panels. This is beneficial for quickly heating the cleaning liquid, significantly improving the winter de-icing and daily decontamination effects, ensuring that the cleaning liquid evenly covers the surface of the photovoltaic panels, and achieving dead-angle cleaning. Secondly, it ensures the flexibility of the device's movement and the safety and reliability of the piping system, thereby achieving the ability to adjust the water temperature according to seasonal needs. Warm water is used in winter to accelerate the melting of ice and snow, and normal temperature water is used to clean stains in other seasons, effectively solving the problems of poor seasonal adaptability and poor cleaning effects of traditional cleaning devices.

[0028] Working principle: This invention belongs to the cleaning component in the photovoltaic component. The slide rail 2 is installed on both sides of the photovoltaic panel mounting frame. When it snows in winter and snow accumulates on the surface of the photovoltaic panel, the drive motor 401 is started to drive the sprocket 402 and at the same time drive another sprocket 402 synchronously through the chain 403. At this time, the drive shaft 404 is driven to rotate, and then the guide wheel 3 is driven to roll forward on the opposite side of the guide rail. At this time, the cleaning box 1 is slowly pushed forward on the surface of the photovoltaic panel. Secondly, the rotation of the drive shaft 404 synchronously drives several transmission bevel gears 405 to rotate synchronously, prompting the drive bevel gear 406 to drive the rubber de-icing strip 408 through the transmission rod 407 to break up the frozen thin ice on the surface of the photovoltaic panel, and actually separate from the photovoltaic panel. The drive motor 401 drives the sprocket 402 to drive and at the same time drives the worm 506. At this time, the worm wheel 505 is driven The driving wheel 501 is driven to rotate by the connecting rod 504, and the crawler 502 is driven to rotate at the front side of the cleaning box 1, and the snow pusher 503 moves along the track of the crawler 502, thereby moving the front end of the cleaning box 1 to push the accumulated snow to one side of the photovoltaic panel. When the cleaning box 1 moves on the surface of the photovoltaic panel, the external pipe 706 is stretched and extended with its movement, and the heating coil 701 is started to heat the cleaning liquid transported from the inside of the external pipe 706. The heated cleaning liquid passes through the delivery pipe 703 to the diversion pipe 704, and then is sprayed from the spray head 705 to clean and defrost the photovoltaic panel. In other seasons, the rubber deicing strip 408 is replaced with a cleaning brush, and the cleaning box 1 is controlled in reverse to move on the surface of the photovoltaic panel. The cleaning liquid is sprayed on the surface of the photovoltaic panel, and then the cleaning brush brushes its surface to clean it.
