Description

Technical Field

[0001] This utility model relates to the field of solar power generation technology, and more specifically, to a water guiding and dust removal device for photovoltaic panels. Background Technology

[0002] Photovoltaic power generation is an advanced technology that uses the photovoltaic effect at the semiconductor interface to directly convert light energy into electrical energy. Its core component, the solar panel, consists of numerous solar cells connected in series or parallel. It is responsible for collecting light energy and converting it into direct current (DC). Then, it is controlled by a controller and converted into alternating current (AC) by an inverter. Excess electrical energy is stored in batteries for backup. In actual operation, photovoltaic panels are prone to dust accumulation, which reduces the light absorption rate and affects power generation efficiency. At the same time, rainwater accumulation may cause short circuits and other malfunctions in the panels, shortening their service life. Therefore, a water drainage and dust removal device is required.

[0003] A search revealed Chinese patent application number CN202322946704.5, which discloses a photovoltaic panel water guiding and dust removal device, including a guide and a connector; the guide includes a first guide part and two second guide parts, each of the two second guide parts being connected to one side of the first guide part for connection to the upper frame of the photovoltaic panel; at least one of the second guide parts is provided with a first through channel, and the first guide part is provided with a second through channel;

[0004] Although the aforementioned patent uses connectors to fix the guide to the upper frame of the photovoltaic panel, allowing water to flow outwards when water accumulates on the battery module, and both the second and first guide sections have through channels that act as self-cleaning holes to prevent dust from clogging the flow space below the guide, meaning raindrops can directly impact the easily clogged areas from top to bottom, carrying away some of the blockages, and in heavy rain or heavier downpours, the greater force of the raindrops can knock away and wash away all the blockages, thus achieving self-cleaning, the following shortcomings still exist in use: 1. The device is designed for a specific frame size and cannot be adapted to photovoltaic panel frames of different thicknesses or shapes; 2. Strong winds or hail may damage the protrusions or through channels, causing structural deformation or blockage. However, the structure is an integrated unit, and replacement requires disassembly and reinstallation, which is cumbersome and increases the cost of use.

[0005] Therefore, there is an urgent need for a water guiding and dust removal device for photovoltaic panels to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a water guiding and dust removal device for photovoltaic panels to solve the problems mentioned in the background art.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] A photovoltaic panel water guiding and dust removal device includes a connecting body A, a protrusion A fixedly connected to the outer wall of the connecting body A, and a connecting part A fixedly connected to the outer wall of the connecting body A, and further includes:

[0009] An adjustment assembly includes a cross slide column symmetrically fixedly connected to the top wall of a connecting body A. A connecting body B is slidably connected to the outer wall of the cross slide column. An adjustment screw is rotatably connected to the top wall of the connecting body A, and the adjustment screw is threadedly connected to the connecting body A. A knob is fixedly connected to the outer wall of the adjustment screw, and the knob is rotatably connected to the connecting body A.

[0010] A connecting groove is symmetrically opened on the outer wall of the connecting body B. A connecting plate is slidably connected to the inner wall of the connecting groove, and a symmetrically distributed limiting groove is opened on the outer wall of the connecting plate.

[0011] Protrusion B is fixedly connected to the outer wall of the connecting body B;

[0012] The components are designed for easy disassembly and replacement, and are located on the inner wall of the connecting body B.

[0013] As a preferred technical solution of this application, the easy-to-disassemble and replaceable component includes a limiting block symmetrically slidably connected to the inner wall of the connecting body B, and the limiting block is slidably connected to the limiting groove. A strong spring is fixedly connected to the outer wall of the limiting block, and the end of the strong spring away from the limiting block is fixedly connected to the connecting body B. A guide plate is fixedly connected to the outer wall of the limiting block, and the guide plate is slidably connected to the connecting body B. A pressing plate is fixedly connected to the outer wall of the guide plate.

[0014] As a preferred technical solution of this application, the top wall of the connecting plate is fixedly connected to a first guide portion, the outer wall of the first guide portion is fixedly connected to a second guide portion, the outer wall of the second guide portion is fixedly connected to a connecting portion B, the outer wall of the first guide portion is provided with a first through channel, and the outer wall of the second guide portion is provided with symmetrically distributed second through channels.

[0015] As a preferred technical solution of this application, a battery frame is provided between the connecting part A and the connecting part B, and a photovoltaic panel body is fixedly connected to the top wall of the battery frame.

[0016] As a preferred technical solution of this application, the outer wall of the battery frame abuts against the outer wall of protrusion B, and the outer wall of the battery frame abuts against the outer wall of protrusion A.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In the scheme of this application:

[0019] 1. The adjustable components allow the connecting body B to be adjusted vertically relative to the connecting body A, thereby adapting to photovoltaic panel frames of different thicknesses. This improves compatibility and flexibility, solving the problem in the prior art where the device cannot adapt to photovoltaic panel frames of different thicknesses or shapes for a specific frame size.

[0020] 2. The easily removable and replaceable components allow for convenient disassembly and replacement of the connecting plate. When strong winds or hail damage the protrusion or through-channel, it is not necessary to disassemble and reinstall the entire device; only the damaged connecting plate needs to be removed and replaced. This simplifies the operation process, reduces operating costs, and improves the device's maintenance efficiency. It also solves the problem in existing technologies where strong winds or hail may damage the protrusion or through-channel, leading to structural deformation or blockage. However, since the structure is an integrated unit, replacing the entire device requires disassembly and reinstallation, which is cumbersome and increases operating costs.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0031] The adjustment assembly includes a cross slide column 6 symmetrically fixedly connected to the top wall of the connecting body A3. The outer wall of the cross slide column 6 is slidably connected to the connecting body B7. The top wall of the connecting body A3 is rotatably connected to the adjusting screw 9, and the adjusting screw 9 is threadedly connected to the connecting body A3. The outer wall of the adjusting screw 9 is fixedly connected to the knob 10, and the knob 10 is rotatably connected to the connecting body A3. By rotating the knob 10, the adjusting screw 9 is driven to rotate. Since the adjusting screw 9 is threadedly connected to the connecting body A3, the adjusting screw 9 will move up and down when rotating, thereby pushing or pulling the connecting body B7 to slide on the cross slide column 6, so as to realize the position adjustment of the connecting body B7 relative to the connecting body A3.

[0032] The connecting groove 22 is symmetrically opened on the outer wall of the connecting body B7. The connecting plate 11 is slidably connected to the inner wall of the connecting groove 22. The outer wall of the connecting plate 11 is provided with symmetrically distributed limiting grooves 21.

[0033] Protrusion B8 is fixedly connected to the outer wall of connecting body B7;

[0034] The components are designed for easy disassembly and replacement, and are located on the inner wall of the connecting body B7.

[0035] like Figure 5-6As shown, in a preferred embodiment, based on the above method, the detachable and replaceable component further includes a limiting block 17 symmetrically slidably connected to the inner wall of the connecting body B7, and the limiting block 17 is slidably connected to the limiting groove 21. A strong spring 20 is fixedly connected to the outer wall of the limiting block 17, and the end of the strong spring 20 away from the limiting block 17 is fixedly connected to the connecting body B7. A guide plate 18 is fixedly connected to the outer wall of the limiting block 17, and the guide plate 18 is slidably connected to the connecting body B7. A pressing plate 19 is fixedly connected to the outer wall of the guide plate 18. When the connecting plate 11 needs to be installed, the connecting plate 11 is inserted into the connecting groove 22. The limiting block 17 is squeezed and slides, compressing the strong spring 20. When the limiting block 17 corresponds to the limiting groove 21, the strong spring 20 releases its elastic stored energy and pushes the limiting block 17 to reset, thereby realizing the connection and fixation of the connecting plate 11. When disassembling, simply press the pressing plate 19 to drive the limiting block 17 to slide out of the limiting groove 21.

[0036] like Figure 2 As shown, in a preferred embodiment, based on the above method, a first guide portion 12 is fixedly connected to the top wall of the connecting plate 11, a second guide portion 13 is fixedly connected to the outer wall of the first guide portion 12, a connecting portion B15 is fixedly connected to the outer wall of the second guide portion 13, a first through channel 14 is opened on the outer wall of the first guide portion 12, and a symmetrically distributed second through channel 16 is opened on the outer wall of the second guide portion 13. Water and dust on the photovoltaic panel body 2 are initially guided through the first through channel 14 of the first guide portion 12 under the action of gravity, and then further guided and discharged through the second through channel 16 of the second guide portion 13.

[0037] like Figure 1 As shown, in a preferred embodiment, based on the above method, a battery frame 1 is further provided between the connecting part A4 and the connecting part B15. The top wall of the battery frame 1 is fixedly connected to the photovoltaic panel body 2. The battery frame 1 between the connecting part A4 and the connecting part B15 serves to fix and support the photovoltaic panel body 2.

[0039] Specifically, when using this photovoltaic panel water guiding and dust removal device: rotating the knob 10 drives the adjusting screw 9 to rotate. Since the adjusting screw 9 is threadedly connected to the connecting body A3, it will move up and down when rotating, thereby pushing or pulling the connecting body B7 to slide on the cross slide 6, realizing the position adjustment of the connecting body B7 relative to the connecting body A3. When it is necessary to install the connecting plate 11, insert the connecting plate 11 into the connecting groove 22. Its limiting block 17 will slide under pressure and compress the strong spring 20. When the limiting block 17 corresponds to the limiting groove 21, the strong spring 20 releases its elastic stored energy and pushes the limiting block 17 to reset, thereby realizing the connection and fixation of the connecting plate 11. When disassembling, simply press the pressing plate 19 to drive the limiting block 17 to slide out of the limiting groove 21.
