Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic panel equipment, and in particular relates to a photovoltaic panel assembly and a laying method. Background Art

[0002] The work of photovoltaic panels is based on the photoelectric effect. When sunlight shines on the photovoltaic panel, the photons interact with the electrons in the semiconductor material, excite the electrons and generate current, thereby converting light energy into electrical energy. This process does not generate any form of electromagnetic radiation and is safe for the human body and the environment.

[0003] The components of photovoltaic panels include: Glass, usually ultra-clear glass or low-iron glass, which has the characteristics of high light transmittance and low absorption, which can improve the power generation efficiency of photovoltaic panels. EVA (ethylene-vinyl acetate copolymer) is an adhesive used to bond the various components of photovoltaic panels together. It can also provide a certain buffering effect to protect photovoltaic panels from damage. Cells: The core component of photovoltaic panels, made of silicon wafers, usually containing polycrystalline silicon or monocrystalline silicon. Cells are responsible for converting light energy into electrical energy. Backplane: Used to protect the cells from the influence of the external environment, such as rain, ultraviolet rays, etc. It is usually made of materials such as fluoroplastics or fiberglass. Junction box: Used to connect photovoltaic panels and external devices, such as inverters, etc. It usually contains components such as fuses and diodes to ensure the safe operation of photovoltaic panels.

[0004] Photovoltaic panels are usually laid in vacant locations such as lakes, grasslands, mountains, and roofs for solar power generation. Due to the low number of personnel activities at the laying sites, there is a lack of maintenance. Dust easily accumulates on the surface of photovoltaic panels over a long period of time, resulting in reduced power generation efficiency. Existing manually operated photovoltaic panel cleaning robots require manual operation and the robot needs to be moved to the photovoltaic panel, which has high computing costs in all aspects. Summary of the invention

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: A photovoltaic panel assembly comprises a support frame, wherein the support frame is a rectangular plate structure, and a plurality of photovoltaic panels are sequentially installed on the support frame along the length direction; The support frame is respectively provided with a first card cover and a second card cover corresponding to the high side and the low side, the second card cover and the low side of the support frame form a water tank, and the first card cover and the second card cover have an opening side corresponding to the supporting side of the support frame; A first screw is installed in the first card cover, and a second screw is installed in the second card cover. The first card cover and the second card cover are arranged in parallel and are both rotatably matched with the corresponding card cover end plates. A driving device for driving the first screw axis to rotate is arranged at the end of the first screw; A scrubbing belt is sleeved between the first screw and the second screw.

[0007] Furthermore, the cross-section of the spiral groove corresponding to the first screw and the second screw is arc-shaped, the cross-section of the side where the scrubbing belt and the spiral groove are connected is arc-shaped, and a brush block is fixed on the outer side corresponding to the scrubbing belt, and the brush blocks are arranged at intervals.

[0009] Furthermore, the first screw extends through the first card cover end plate and is installed with a first pulley. A driving device is installed on the lower side of the support frame. The driving device is a motor. A second pulley is installed at the output end of the motor. The first pulley and the second pulley are driven by a transmission belt.

[0010] The first card cover is adjustable, and the first card cover has an extension portion at the corresponding end position, and the extension portion covers the side of the support frame after extension, and the extension portion and the side of the support frame are both provided with holes for fixing with bolts. The support frame has side panels on both sides, and the side panels are right-angled triangles. A mounting plate is horizontally fixed to the lower side of the side panels, and the mounting plate is horizontally arranged, and the mounting plate is used to support and adjust the installation position of the motor.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] like Figure 1-2 As shown: A photovoltaic panel assembly includes a support frame 3, which is a rectangular plate structure and is tilted to adapt to the direct angle of the sun, with a tilt angle of about 25°. A plurality of photovoltaic panels 4 are sequentially installed along the length direction of the support frame 3; the photovoltaic panels 4 are rectangular plate structures, and the corresponding back plate parts are attached to the support frame and fixed to the support frame, and each photovoltaic panel 4 is evenly and equidistantly arranged along the length direction of the support frame.

[0026] The first card cover 1 and the second card cover 2 are respectively installed on the high side and the low side of the support frame 3, the second card cover 2 and the low side of the support frame 3 form a water tank, and the first card cover 1 and the second card cover 2 have opening sides corresponding to the supporting side of the support frame 3; A first screw 11 is installed in the first card cover 1, and a second screw 21 is installed in the second card cover 2. The first card cover 1 and the second card cover 2 are arranged in parallel and are rotatably matched with the corresponding card cover end plates. A driving device is arranged at the end of the first screw 11 to drive the axis of the first screw 11 to rotate. A scrubbing belt 6 is sleeved between the first screw 11 and the second screw 21. The scrubbing belt 6 sleeves the first screw 11 and the second screw 21 on the corresponding inner side, is inserted into the thread groove of the corresponding screw, and is tightened, and the outer side is pressed against the photovoltaic panel 4, driving the first screw 11 to rotate. The rotation of the first screw 11 drives the second screw 21 to rotate through the scrubbing belt 6, so that the outer side of the scrubbing belt 6 rubs against the surface of the photovoltaic panel 4 to perform the scrubbing process. Since the scrubbing belt 6 is embedded in the thread groove corresponding to the screw, the scrubbing belt 6 moves along the thread direction of the thread groove during rotation, and the overall scrubbing belt 6 moves horizontally in the length direction of the corresponding support frame, so that the surfaces of multiple photovoltaic panels 4 on the support frame 3 can be cleaned.

[0027] The second card cover 2 corresponding to the lower side of the support frame 3 forms a water tank, and water is filled in the water tank. After moving to the water tank, the washing belt 6 is immersed in water to moisten the washing belt 6, so that the caking dirt that is difficult to clean can be cleaned. With the circulating transmission of the washing belt, the dirt contaminated by the washing belt can also be cleaned by the water in the water tank, so as to keep the washing belt clean and maintain an efficient cleaning process.

[0028] When the scrubbing belt 6 moves from one side of the support frame 3 to the other side, the first screw 11 is rotated in the opposite direction by the driving device to make the scrubbing belt return, and the scrubbing belt is cleaned in a reciprocating manner. Compared with the existing photovoltaic panel cleaning robot and photovoltaic modules with cleaning devices, the device of the present invention is simpler and more efficient, and has low equipment cost and is easy to maintain.

[0029] like Figure 3 As shown: the cross section of the spiral groove corresponding to the first screw and the second screw 21 is arc-shaped, the cross section of the side where the scrubbing belt 6 and the spiral groove are connected is arc-shaped, and a brush block 61 is fixed on the outer side corresponding to the scrubbing belt 6, and the brush blocks 61 are arranged at intervals. The cross section of the spiral groove and the corresponding scrubbing belt 6 are arc-shaped contact surfaces, which helps to reduce the wear of the belt during the transmission process. The brush blocks 61 are composed of bristles and a fixed layer, which are arranged at intervals and are used to replace the scrubbing belt to contact the surface of the photovoltaic panel 4 to prevent the rubber belt from causing scratches on the surface of the photovoltaic panel. At the same time, the bristles can absorb water to improve the scrubbing effect. The brush blocks can be replaced in a targeted manner.

[0030] like Figure 2 As shown: the end plates on both sides of the second card cover 2 are connected with a water inlet pipe 22 and a water outlet pipe 23 respectively. It is used to fill the card slot formed by the second card cover with water. The water inlet pipe has a controllable valve. The water inlet pipe and the water outlet pipe work at the same time, so that the water in the water tank is in a flowing state, which is used to keep the water clean and prevent secondary pollution caused by sewage cleaning. The first screw rod 11 extends through the end plate of the first card cover 1 and is installed with a first pulley 13. The lower side of the support frame 3 is installed with a driving device, which is a motor 5. The output end of the motor 5 is installed with a second pulley 51. The first pulley 13 and the second pulley 51 are driven by a transmission belt 52. The ends of the first card cover 1 and the second card cover 2 are both provided with a sleeve corresponding to the end of the screw rod, which is used for the stable rotation of the screw rod. The first card cover 1 is adjustable. The first card cover 1 has an extension part 12 at the corresponding end position. The extension part extends in the direction of the end length. After the extension part 12 is extended, it covers the side of the support frame 3. The extension part 12 and the side of the support frame 3 are both provided with holes for fixing by bolts. The first card cover 1 can be moved along the width direction of the support frame to control the distance between the first screw rod 11 and the second screw rod 21, so that the washing belt 6 can be tightened. After adjusting the distance, the first card cover 1 is fixed by bolts through the side extension part 12.

[0031] like Figure 4 As shown: the support frame 3 has side panels 31 on both sides, the side panels are right-angled triangles, and a mounting plate 32 is horizontally fixed to the lower side of the side panel 31. The mounting plate 32 is horizontally set and is used to support and adjust the installation position of the motor 5.

[0032] like Figure 5 As shown: a plurality of support pipes 7 are installed between the mounting plate 32 and the ground, and the two ends of the support pipes 7 are butt flanges. They are used to support and elevate the overall support frame 3. The ends of the support pipes 7 are fixed to the mounting plate 32 through a flange structure. The support pipes are pipe structures and can also be used to sleeve support rods. The support rods are used to be embedded deep in the soil to stabilize the support frame. They are suitable for high mountains, lakes and other windy locations. The support rods are pre-buried, and then the support pipes are sleeved and positioned for support.

[0033] like Figure 6 As shown: the support frame 3 has a mounting groove 33 for mounting the photovoltaic panel 4, the mounting groove 33 is a through groove, and the side of the mounting groove 33 has a frame 34 for supporting the side of the photovoltaic panel 4, and the frame 34 has an arc plate 35 at the corresponding corner position, and the arc plate 35 has a mounting hole. Since the photovoltaic panel 4 has a thickness, the photovoltaic panel 4 is embedded in the support frame 3 by opening the mounting groove 33, so that the upper plane of the photovoltaic panel 4 and the upper side of the support frame 3 remain in the same plane, which is convenient for the washing belt 6 to move on the upper side of the support frame 3 without obstruction.

[0034] A method for laying a photovoltaic panel assembly comprises the following steps: 1. Install the support frame 3 first. According to the installation position of the support frame 3, first locate and install the support pipe 7. Determine whether to embed the positioning column according to the installation environment to ensure the installation stability of the support frame 3. 2 Install the photovoltaic panel 4, match the photovoltaic panel 4 with the mounting groove 33 one by one, and fix them through the mounting holes; 3 Install the first card cover 1 and the washing belt 6, adjust the installation position of the first card cover 1, make the washing belt 6 tight, align the washing belt 6 with the spiral grooves corresponding to the first screw 11 and the second screw 21, and fix the first card cover 1 with bolts; The motor 5 is installed, and the first pulley 13 and the second pulley 51 are installed at the ends of the first screw rod 11 and the motor 5, respectively, and the transmission belt 52 is tightened to perform transmission cooperation, thereby completing the construction and laying process.
