Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel cleaning machines, specifically to a beam tensioning device for photovoltaic panel cleaning machines and photovoltaic panel cleaning equipment. Background Technology

[0002] A single power generation unit in a large-scale photovoltaic (PV) power plant typically consists of multiple rows of individual photovoltaic panels, requiring regular cleaning using a PV panel cleaning machine. The front roller brush of this machine is usually quite long, typically 5 to 6 meters. The roller brush is mounted to both ends of a crossbeam via bearing seats, and motors driving the roller brush rotation are located at both ends of the crossbeam. The middle section of the crossbeam is hinged to the front end of the cleaning machine's extension arm. Furthermore, the nozzles used to clean the photovoltaic panels are also located inside the crossbeam, increasing its weight and impacting its structural strength to some extent. The crossbeam thus forms a cantilevered structure, hinged in the middle to the front end of the extension arm and supporting the roller brushes at both ends. Considering the overall load-bearing capacity (maximum load-bearing capacity of the front end of the extension arm), the crossbeam and roller brushes must be designed to be as lightweight as possible while ensuring normal operation. Therefore, aluminum alloy can be used for the crossbeam, but aluminum alloy has relatively poor strength and rigidity. Once the crossbeam bends and deforms, it will affect the normal operation of the roller brush. Therefore, it is necessary to design a tensioning device that can enhance the aluminum alloy crossbeam to overcome the problem of the two ends of the crossbeam bending downward relative to the middle. Utility Model Content

[0003] The purpose of this utility model is to provide a beam tensioning device and a photovoltaic panel cleaning equipment for a photovoltaic panel cleaning machine, so as to solve the technical problem that the two ends of the beam bend downward relative to the middle in the prior art.

[0004] To achieve this objective, the present invention adopts the following technical solution: The photovoltaic panel cleaning machine's crossbeam tensioning device includes a traction component and a height adjustment mechanism. The two ends of the traction component are connected to the two ends of the crossbeam, and the two ends of the crossbeam are used to install roller brushes and motors for driving the roller brushes to rotate. The middle of the traction component is fixed by a height adjustment mechanism. A hinge seat is provided in the middle of the crossbeam. The height adjustment mechanism is installed on the hinge seat. The height of the height adjustment mechanism relative to the hinge seat can be adjusted and locked in a certain position after adjustment. The hinged base is hinged to the extension arm of the photovoltaic panel cleaning machine.

[0005] Preferably, the aforementioned height adjustment mechanism includes a lifting plate, a support plate, a stud, and a nut, and the hinge seat includes a vertically arranged vertical plate; The bottom of the stud is fixedly connected to the top of the lifting plate, the support plate is fixedly installed on the top of the vertical plate, and the stud passes through the support plate and is connected to the nut by a thread. The lifting plate is connected to the middle position of the traction component via a locating roller.

[0006] To facilitate the fixing of the traction component, a limiting pressure roller is also provided on the upper end of the aforementioned chuck, and the traction component is located between the chuck and the limiting pressure roller.

[0007] The limiting pressure roller of this utility model is fixedly provided with a through-post one, and the chuck is fixedly provided with a through-post two. An oblong hole is opened on the vertical plate; both through-post one and through-post two pass through the oblong hole and are rotatably connected to the lifting plate.

[0008] The preferred installation method for Through Column 2 and Through Column 1 is to have two through holes on the lifting plate for Through Column 2 and Through Column 1 to pass through, and external threads on the ends of Through Column 2 and Through Column 1, nuts are installed on the external threads of Through Column 2 and Through Column 1.

[0009] Preferably, in the aforementioned photovoltaic panel cleaning machine beam tensioning device, the traction component is any one or more of steel wire rope, chain, or iron chain connected in series.

[0011] Preferably, the aforementioned photovoltaic panel cleaning machine beam tensioning device has two vertical plates, which are symmetrically installed on both sides of the beam; there are also two traction components and two height adjustment mechanisms, which are respectively installed on the two vertical plates.

[0012] To further adjust the extension range of the traction component, the aforementioned photovoltaic panel cleaning machine beam tensioning device allows the two ends of the traction component to be extendable and adjustable relative to the two ends of the beam.

[0013] A photovoltaic panel cleaning device, comprising a photovoltaic panel cleaning machine beam tensioning device according to any one of the preceding claims, wherein the photovoltaic panel cleaning device is hinged to the hinge seat via an extension arm.

[0014] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model improves the support performance of the crossbeam for the roller brush by adding a diagonal traction structure at the upper end of the crossbeam, thereby avoiding the crossbeam from deflecting downwards and keeping the crossbeam in a horizontal state as much as possible.

[0015] The height adjustment mechanism of this utility model can adjust the tension of the traction component and the diagonal pull arm. Even after long-term use of the equipment, the crossbeam can still be straightened through the height adjustment mechanism.

[0016] Because of the aforementioned inclined structure, the crossbeam does not need to be made of heavy steel, but only aluminum alloy profiles are needed to support the roller brush. This is beneficial for achieving lightweight equipment and also facilitates the arrangement of water channels and other components on the crossbeam. Attached Figure Description

Detailed Implementation

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0021] like Figures 1 to 4 As shown, this embodiment discloses a beam tensioning device for a photovoltaic panel cleaning machine, including a traction component 1 and a height adjustment mechanism 4. The two ends of the traction component 1 are connected to the two ends of the beam 5. The two ends of the beam 5 are provided with rotating supports (e.g., bearing seats). The rotating supports are used to install roller brushes 6 and motors for driving the roller brushes 6 to rotate. The motor is usually a hydraulic motor and can usually be installed at one end of the beam 5.

[0022] The traction component 1 is fixed in the middle by a height adjustment mechanism 4. A hinge seat 5a is provided in the middle of the crossbeam 5. The hinge seat 5a is used to hinge the extension arm of the photovoltaic panel cleaning machine, thereby realizing the connection between the roller brush assembly and the main unit. The two ends of the traction component 1 are telescopically adjustable relative to the two ends of the crossbeam 5, thereby increasing the adjustment range.

[0023] The height adjustment mechanism 4 is installed on the hinge seat 5a. The height of the height adjustment mechanism 4 relative to the hinge seat 5a is adjustable and can be locked in a certain position relative to the hinge seat 5a after adjustment, thereby ensuring that the pulling force of the traction member 1 is constant. As can be seen from the above description, the traction member 1 in this embodiment is similar to an inclined pulling device. By raising the two ends of the crossbeam 5 upwards in a way that is higher in the middle and lower at both ends, the downward deflection of the crossbeam 5 is alleviated, and the crossbeam 5 is kept as horizontal as possible.

[0024] The height adjustment mechanism 4 includes a lifting plate 4a, a support plate 4b, a stud 4c, and a nut 4d. The hinge seat 5a includes a vertically arranged vertical plate 5a1. The bottom of the stud 4c is fixedly connected to the top of the lifting plate 4a, and the support plate 4b is fixedly installed on the top of the vertical plate 5a1. The stud 4c passes through the support plate 4b and is threadedly connected to the nut 4d. That is, the support plate 4b engages with the stud 4c through a hole, and the height of the support plate 4b can be adjusted by rotating the nut 4d. The main function of the height adjustment mechanism is to adjust the pulling force of the traction member 1 by adjusting the highest point of the middle position of the traction member 1, and at the same time, it can increase the lever arm of the traction member 1 for lifting the crossbeam 1 upward. This lever arm is equal to the distance between the highest point of the traction member 1 and the upper surface of the crossbeam 5.

[0025] The lifting plate 4a is connected to the middle position of the traction component 1 via a chuck 2. To prevent the traction component 1 from disengaging from the chuck 2, a limiting pressure roller 3 is also provided at the upper end of the chuck 2, and the traction component 1 is positioned between the chuck 2 and the limiting pressure roller 3. In this embodiment, the traction component 1 can be any one or more of wire rope, chain, or iron chain connected in series, with wire rope being the most suitable. When using wire rope, a first annular groove is provided on the outer edge of the chuck 2 for the wire rope to engage, and a second annular groove is provided on the limiting pressure roller, with the wire rope positioned between the first and second annular grooves. The first and second annular grooves are not shown in the attached drawings. Figure 3 The position and connection relationship of the annular groove can be determined without any doubt.

[0026] Ideally, there should be two vertical plates 5a1, and the two vertical plates 5a1 should be symmetrically installed on both sides of the crossbeam 5; there should be two traction components 1 and two height adjustment mechanisms 4, and the two traction components 1 and two height adjustment mechanisms 4 should be installed on the two vertical plates 5a1 respectively.

[0027] In this embodiment, the installation method of the limiting pressure roller 3 and the chuck 2 is as follows: the limiting pressure roller 3 is fixedly provided with a through-post 3a, the chuck 2 is fixedly provided with a through-post 2a, and the vertical plate 5a1 is provided with an oblong hole 5a2; both the through-post 3a and the through-post 2a pass through the oblong hole 5a2 and are rotatably connected to the lifting plate 4a. By moving the through-post 3a and the through-post 2a up and down inside the oblong hole 5a2, the height and spacing of the two can be adjusted.

[0028] Specifically, the lifting plate 4a has two through holes for the second through column 2a and the first through column 3a to pass through. The ends of the second through column 2a and the first through column 3a are provided with external threads, and nuts are threaded onto the external threads of the second through column 2a and the first through column 3a. The second through column 2a and the first through column 3a can adopt a stepped shaft design.

[0029] Compared with the prior art, this embodiment improves the support performance of the crossbeam 5 for the roller brush 5 by adding a diagonal bracing structure (traction member 1) to the upper end of the crossbeam 5, thereby avoiding the crossbeam 5 from deflecting downwards as much as possible and keeping the crossbeam 5 in a horizontal state.

[0030] In this embodiment, the height adjustment mechanism 4 can adjust the tension of the traction component 1 and the inclined pull arm. Even after long-term use of the equipment, the crossbeam 1 can still be straightened through the height adjustment mechanism 4.

[0031] Because of the aforementioned inclined structure, the crossbeam 1 does not need to be made of heavy steel, but only aluminum alloy profiles are needed to support the roller brush 6. This is beneficial for achieving lightweight equipment and also facilitates the arrangement of water channels and other components on the crossbeam.

[0032] This embodiment also discloses a photovoltaic panel cleaning device, which includes the aforementioned photovoltaic panel cleaning machine beam tensioning device, wherein the photovoltaic panel cleaning device is hinged to the hinge seat 5a via an extension arm.

[0033] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
