Description

Technical Field

[0001] The utility model belongs to the field of photovoltaic components, and more specifically, particularly relates to a photovoltaic component snow cleaning system. Background Art

[0002] Photovoltaic power stations use sunlight to make batteries absorb light energy. The larger the area, the more light energy is absorbed. Photovoltaic power generation converts light energy into electrical energy through the photovoltaic effect at the semiconductor interface. To ensure that the absorbed light energy is sufficient, photovoltaic power stations have a large number of outer panels placed over a large area, and the back end will use a cleaning system to inspect them.

[0003] Since there are a large number of external panels in the photovoltaic power station, in order to ensure its absorption effect, a surface cleaning machine is installed on the side. The equipment needs to check the panel surface from the outside to see the degree of dust coverage, and use the cleaning system to operate the cleaning machine to clean the outer panels.

[0004] Based on the above, the inventors of the present invention have found that the existing photovoltaic module cleaning mainly has the following shortcomings, such as:

[0005] When the outer plate is in snowy weather, it is covered by accumulated snow. If the cleaning system is used directly to scrape, the snow will pile up and be pushed to form harder snow blocks, which will make subsequent cleaning more difficult and will cause a certain degree of damage to the outer plate and equipment.

[0006] Therefore, it is necessary to propose a photovoltaic module snow cleaning system. Utility Model Content

[0007] In order to solve the problem that when the outer plate of the above-mentioned technology is in snowy weather, the outer plate is covered by accumulated snow. If the cleaning system is directly used to scrape, the accumulated snow will be pushed together and formed into harder snow blocks, which will be more difficult for subsequent cleaning and will cause a certain degree of damage to the outer plate and equipment.

[0008] The purpose and effect of the photovoltaic module snow cleaning system of the utility model are achieved by the following specific technical means:

[0009] Its structure includes a vertical bracket, a cleaning machine, a photovoltaic outer panel, a fixed frame, a slide frame, a translation bracket, a moving wheel, and a control box. The cleaning machine is connected to the side of the vertical bracket and is movable. The cleaning machine is installed in the groove of the slide frame and can move along the direction of the groove. The photovoltaic outer panel is fixed in the groove of the slide frame. The fixed frame is installed on the back of the photovoltaic outer panel. The moving wheel is placed above the translation bracket and can move horizontally. The control box is connected between the vertical bracket and the cleaning machine.

[0010] The cleaning machine includes a connecting body, an internal grid, an outer shell, a central axis, and a scraping body. The internal grid and the outer shell are an integrated structure. The connecting body is placed inside the internal grid. The central axis runs through the connecting body and its ends are fixed to the outer shell. The scraping body is installed on the outside of the central axis.

[0011] As a further improvement of the utility model, the scraper body includes a push body and a main scraper. A central axis runs through the inside of the main scraper. A push body is fitted between every two main scrapers. The main scrapers are evenly distributed and installed with the central axis as the horizontal line. The outer side of the push body has a certain curvature.

[0012] As a further improvement of the utility model, the pusher includes a convex ball, a soft body, and an elastic block. The soft body is attached to the outer surface of the elastic block, and the convex ball is symmetrically embedded in the inside of both sides of the soft body. The soft body is made of rubber soft material and is easy to stretch and shrink. The elastic block has resilience.

[0013] As a further improvement of the present invention, the main scraper includes a hard block, a buffer layer, and a connecting block. The connecting block is nested on the outside of the central axis. The buffer layer is fitted between the connecting block and the hard block and the hard block is located on the outside. The hard block and the connecting block are inelastic and have a certain hardness.

[0014] As a further improvement of the utility model, the central axis includes an axis body and an outer sleeve ring. The outer sleeve ring is nested on the outside of the axis body. The outside of the outer sleeve ring is connected to the scraper body. The outer sleeve ring engages with the outer layer object to perform a limiting function.

[0015] As a further improvement of the utility model, the outer sleeve includes a fixed ball, an extrusion layer, and a connecting ball. The fixed ball is connected to the shaft body. The extrusion layer is attached to the outside of the fixed ball and the connecting ball. The connecting ball and the fixed ball have a certain hardness. The extrusion layer can be compressed by extrusion and has a rebound effect.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The main scraper and the pusher body will accumulate and scrape the snow. The resistance of the snow blocks will be greater, and the resistance will squeeze the soft body. The elastic block will maintain the rebound force to support the soft body. When the soft body is stretched and deformed, the hardness of the convex ball will form a protruding hard block on the surface of the soft body, squeezing the snow blocks that squeeze the soft body. The agglomerated snow blocks are split into small parts in the middle buffer layer to prevent the hard blocks from being damaged by stubborn snow blocks. The rebound effect of the elastic block and the soft body prevents the accumulated snow from sticking to the surface of the scraper body, which protects the surface of the photovoltaic outer panel and the scraper body of the cleaner itself, and can smoothly sweep the snow to prevent the snow blocks from sticking to the outer panel and the cleaner.

[0018] 2. A connecting ball is arranged inside the outer sleeve ring to which the scraper body is connected. When the scraper body is subjected to a harder external force, its resistance becomes larger, and the extrusion layer is squeezed and slightly rotated along the axis to avoid damage to the surface of the photovoltaic outer panel and prevent the scraper body from scraping hard against it, thus protecting both of them and being able to adjust and adapt itself according to the requirements of the outer panel surface.

DETAILED DESCRIPTION

[0028] The utility model is further described below in conjunction with the accompanying drawings:

[0029] Embodiment 1:

[0030] As attached Figure 1 To Attachment Figure 5 As shown:

[0031] The utility model provides a photovoltaic component snow cleaning system, which structure includes a vertical bracket 1, a cleaning machine 2, a photovoltaic outer panel 3, a fixed frame 4, a slide frame 5, a translation bracket 6, a moving wheel 7, and a control box machine 8. The cleaning machine 2 is connected to the side of the vertical bracket 1 and is movable. The cleaning machine 2 is installed in the groove of the slide frame 5 and can move along the direction of the groove. The photovoltaic outer panel 3 is fixed in the groove of the slide frame 5. The fixed frame 4 is installed on the back of the photovoltaic outer panel 3. The moving wheel 7 is placed above the translation bracket 6 and can move horizontally. The control box machine 8 is connected between the vertical bracket 1 and the cleaning machine 2.

[0032] The cleaning machine 2 includes a connecting body a1, an internal grid a2, an outer shell a3, a central axis a4, and a scraping body a5. The internal grid a2 and the outer shell a3 are an integrated structure. The connecting body a1 is placed inside the internal grid a2. The central axis a4 runs through the connecting body a1 and its two ends are fixed to the two ends of the outer shell a3. The scraping body a5 is installed on the outside of the central axis a4.

[0033] Among them, the scraper body a5 includes a push body 51 and a main scraper 52. The main scraper 52 has a central axis a4 running through it. A push body 51 is fitted between every two main scrapers 52. The main scrapers 52 are evenly distributed and installed with the central axis as the horizontal line. The outer side of the push body 51 has a certain curvature. The curvature formed between the push body 51 and the main scraper 52 can better wrap and shovel the snow blocks.

[0034] Among them, the pushing body 51 includes a convex ball 101, a soft body 102, and an elastic block 103. The soft body 102 is fitted to the outer surface of the elastic block 103, and the convex ball 101 is symmetrically embedded in the inside of both sides of the soft body 102. The soft body 102 is made of rubber soft material and is easy to stretch and shrink. The elastic block 103 has resilience. When the soft body 102 is squeezed and fitted, the convex ball 101 will push out the soft body 102 to deform it, and the elastic block 103 forms a resistance to external force.

[0035] Among them, the main scraper 52 includes a hard block b1, a buffer layer b2, and a connecting block b3. The connecting block b3 is nested on the outside of the central axis a4. The buffer layer b2 is attached between the connecting block b3 and the hard block b1, and the hard block b1 is located on the outside. The hard block b1 and the connecting block b3 are inelastic and have a certain hardness. The buffer layer b2 gives the hard block b1 a buffering effect, so that it can flexibly push foreign objects.

[0036] The specific usage and function of this embodiment are as follows:

[0037] In the utility model, since the area of ​​the photovoltaic power station is large, the usual operation and maintenance and data control are all processed and operated through the system. When it is in snowy weather, the operator can control the cleaning machine 2 through the original control system to make the cleaning machine 2 move horizontally along the slide rail frame 5, so as to clean the surface of the photovoltaic outer panel 3. The photovoltaic outer panel 3 has a certain inclination angle, so most of the snow will be at the lower end of the photovoltaic outer panel 3. When the cleaning machine 2 moves horizontally, it mainly contacts the surface snow of the photovoltaic outer panel 3 through the scraper a5, and the main scraper 52 and the pushing body 51 accumulate and scrape the snow. The snow is accumulated together by external force, and continuous pushing will form hard snow blocks. The resistance of the snow blocks during pushing will be greater, and its resistance will squeeze the software 102, and the software 102 will bounce back. The elastic block 103 pushes in the direction of the soft body 102, and the elastic block 103 will maintain the rebound force to support the soft body 102. When the soft body 102 is stretched and deformed, the hardness of the convex ball 101 will form a protruding hard block on the surface of the soft body 102, and the snow blocks that squeeze the soft body 102 are squeezed and stressed, and the agglomerated snow blocks are split into small parts, and the push is continued in accordance with the slope of the hard block b1. The hard block b1 is pushed in the front section, and the middle buffer layer b2 prevents the hard block b1 from being damaged by stubborn snow blocks that cannot be pushed. It provides a certain buffering and angle change effect on the hard block b1. The rebound effect of the elastic block 103 and the soft body 102 prevents the accumulated snow from sticking to the surface of the scraper a5, so that the accumulated snow can slide off effectively and smoothly, and protects the surface of the photovoltaic outer panel 3 and the scraper a5 of the cleaning machine 2 itself, and can smoothly remove the accumulated snow.

[0038] Embodiment 2:

[0039] As attached Figure 6 To Attachment Figure 7 As shown:

[0040] Among them, the central axis a4 includes an axis body 001 and an outer ring 002. The outer ring 002 is nested on the outside of the axis body 001. The outer side of the outer ring 002 is connected to the scraper a5. The outer ring 002 connects with the outer object to limit the position. The outer ring 002 plays the role of limiting and buffering.

[0041] Among them, the outer ring 002 includes a fixed ball w01, an extrusion layer w02, and a connecting ball w03. The fixed ball w01 is connected to the shaft body 001, and the extrusion layer w02 is attached to the outside of the fixed ball w01 and the connecting ball w03. The connecting ball w03 and the fixed ball w01 have a certain hardness. The extrusion layer w02 can be compressed by extrusion and has a rebound effect. The fixed ball w01 limits the maximum range of movement of the object and plays a role of fixing force.

[0042] The specific usage and function of this embodiment are as follows:

[0043] In the utility model, when the control system operates the cleaning machine 2 so that the scraper a5 is moving, it will encounter some melted snow blocks adhering to the surface of the photovoltaic outer panel 3. The outer sleeve 002 to which the scraper a5 is connected is provided with a connecting ball w03. When the scraper a5 is subjected to a harder external force, its resistance becomes greater, and the connected connecting ball w03 will squeeze the extrusion layer w02 and rotate slightly along the shaft 001. The fixed ball w01 limits the space of the extrusion layer w02 squeezed by the connecting ball w03, so that the scraper a5 will not forcibly scrape the snow blocks that have been adhered to the photovoltaic outer panel 3, thereby avoiding damage to the surface of the photovoltaic outer panel 3 and preventing the scraper a5 from scraping hard with it, thereby protecting both.

[0044] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
