[0002] A photovoltaic curtain wall is an accessory device used for installation on the exterior wall of a building to absorb solar energy and convert it into electrical energy, and it has been widely used in the field of photoelectric conversion; During the installation process of the photovoltaic curtain wall, it is usually necessary to install keels on the wall, and then the four sides of the photovoltaic curtain wall are directly fixed to the wall keels by welding (or by bolt connection) to make the photovoltaic curtain wall fit the wall, and rely on the keels to support the weight of the photovoltaic curtain wall. However, the inner side of the photovoltaic curtain wall fits the wall, and the distance between them is very small. The electrical connection lines of the photovoltaic curtain wall are also arranged on the side close to the wall, which makes it inconvenient to wire or repair the lines of the photovoltaic curtain wall. Summary of the Invention

[0004] Technical Solutions To achieve the above object, the present invention is realized through the following technical solutions: The present invention provides a construction and installation device for a large-span composite phase-change glass photovoltaic curtain wall, including a mounting plate for connecting with the wall structure. L-shaped rods are fixedly installed on both sides of the mounting plate. Two rotating rods are rotatably installed between the two L-shaped rods through a rotating shaft. The two rotating rods are arranged at intervals, and a bending groove is formed protruding on the rotating rod; It further includes a connecting plate fixedly installed on the photovoltaic panel. A plurality of bending plates are arranged at intervals on the connecting plate. When the photovoltaic panel is installed between the two L-shaped rods, the bending plates are inserted into the bending grooves, and the lower part of the bending groove is sealed.

[0005] Further, a through hole is provided on the rotating rod, the middle part of the through hole is communicated with the bending groove, a limiting through hole corresponding to the through hole is provided on the bending plate, and a limiting block for passing through the through hole and the limiting through hole is provided on the L-shaped rod.

[0006] Further, the bent plate includes a bent section fixedly connected to the connecting plate and an arc section away from the connecting plate. The bent section and the arc section are of an integrally formed structure, and the arc section is installed in interference fit with the inside of the bent groove.

[0007] Further, a first sliding frame is further included. The top view projection outline of the first sliding frame is U-shaped. A scraping box for scraping dust on the photovoltaic panel is arranged on the first sliding frame. Linear motors are arranged at both ends of the first sliding frame, and guide rails for guiding the up and down movement of the linear motors are arranged on the L-shaped rod.

[0008] Further, a chute is arranged on the scraping box. A scraping plate is slidably installed inside the chute. Elastic members are arranged above and below the scraping plate, and the other ends of the elastic members are connected to the scraping box. The elastic members are used to drive the scraping plate to move towards the scraping box, and rotating shafts are rotatably installed at both ends of the scraping plate.

[0009] Further, a second sliding frame is arranged below the first sliding frame. The second sliding frame has the same structure as the first sliding frame. A limiting wedge block for driving the scraping plate to move towards the photovoltaic panel is arranged on the second sliding frame. When the second sliding frame approaches the first sliding frame, the limiting wedge block drives the scraping plate to approach the photovoltaic panel by restricting the position of the rotating shaft.

[0010] Further, a guiding frame is fixedly installed on the second sliding frame. One end of the limiting block away from the bent plate is slidably installed inside the guiding frame. A return spring for driving the limiting block to move towards the guiding frame is installed inside the guiding frame. A limiting inclined plate is fixedly installed on the limiting block, and an L-shaped limiting rod for restricting the sliding position of the limiting inclined plate is fixedly installed on the first sliding frame.

[0011] Further, the limiting inclined plate includes a vertical section and a limiting section. The lower part of the limiting section inclines towards the guiding frame. When the limiting wedge block restricts the scraping plate from moving towards the photovoltaic panel, the lowermost part of the L-shaped limiting rod reaches the vertical section.

[0012] Further, both ends of the rotating shaft pass through two rotating rods and are fixedly connected to the two rotating rods. Both ends of the rotating shaft are rotatably connected to the two L-shaped rods respectively.

[0013] Beneficial Effects The technical solution provided by the present invention has the following beneficial effects compared with the known public technologies: 1. In the present invention, by rotatably installing two rotating rods between two L-shaped rods, and at the same time arranging a connecting plate on the back of the photovoltaic panel. When installing and connecting the photovoltaic panel, first fix the mounting plate on the wall, then fix the connecting plate on the back of the photovoltaic panel, and then hoist the photovoltaic panel and the connecting plate on its back to a position slightly above the sides of the two rotating rods. As the photovoltaic panel moves downward, insert the bending plates on the connecting plate into the corresponding bending grooves respectively to complete the installation of the photovoltaic panel. During the wiring process, by rotating the photovoltaic panel, the rotating rods can rotate around the rotating shaft, which can facilitate the rotation of the photovoltaic panel during wiring or maintenance, and more conveniently complete the wiring operation of the photovoltaic panel.

[0014] 2. In the present invention, by arranging a first sliding frame on the outside of the photovoltaic panel and driving the first sliding frame to be installed on the L-shaped rod through a linear motor. When dust accumulates on the surface of the photovoltaic panel, the linear motor drives the first sliding frame to move downward, so that the scraper can slide on the surface of the photovoltaic panel, and the dust deposited on the surface of the photovoltaic panel can be scraped downward, which conveniently cleans the surface of the photovoltaic panel. In addition, the end of the scraper close to the photovoltaic panel is in an isosceles trapezoid shape, and a wiping rubber strip is wrapped around the end surface of the scraper in contact with the surface of the photovoltaic panel.

[0015] 3. In the present invention, by arranging a limit wedge on the second sliding frame, by adjusting the vertical distance between the second sliding frame and the first sliding frame, the limit wedge can conveniently drive the scraper to approach or move away from the surface of the photovoltaic panel, and the dust scraping force on the photovoltaic panel can be controlled, so that the first sliding frame only scrapes and cleans the photovoltaic panel during the downward movement, which can reduce scratches on the surface of the photovoltaic panel and also prevent the dust on the scraper from adhering to the surface of the photovoltaic panel again during the upward movement.

[0016] 4. In the present invention, by slidably installing a limit block on the second sliding frame. In strong wind weather, first drive the second sliding frame upward to the middle of the photovoltaic panel, so that the limit block on the second sliding frame is directly opposite to the through hole. Then, by driving the first sliding frame downward, the L-shaped limit rod on the first sliding frame can be driven to move downward. When the lower end of the L-shaped limit rod abuts against the limit section of the limit inclined plate, as the L-shaped limit rod continues to move downward, the limit block moves towards the through hole direction, and the limit block can pass through the through hole and the limit through hole, which can conveniently further fix the position of the bending plate in the bending groove, and at the same time can also prevent the rotating rod from rotating in strong wind weather.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0021] The following further describes the present invention in combination with embodiments.

[0022] Embodiment: A construction and installation device for a large-span composite phase-change glass photovoltaic curtain wall, as Figure 1 - Figure 4 shown, including a mounting plate 2 for connecting with a wall structure, L-shaped rods 21 are fixedly installed on both sides of the mounting plate 2, two rotating rods 23 are rotatably installed between the two L-shaped rods 21 through a rotating shaft 22, the two rotating rods 23 are arranged at intervals, and a bending groove 2302 is formed protruding on the rotating rod 23; It further includes a connecting plate 11 fixedly installed on the photovoltaic panel 1, a plurality of bending plates 12 are arranged at intervals on the connecting plate 11, when the photovoltaic panel 1 is installed between the two L-shaped rods 21, the bending plates 12 are inserted into the bending groove 2302, and the lower part of the bending groove 2302 is sealed.

[0023] In the present invention, by rotatably installing two rotating rods 23 between the two L-shaped rods 21, and at the same time arranging a connecting plate 11 on the back of the photovoltaic panel 1, when connecting and installing the photovoltaic panel 1, first fix the mounting plate 2 on the wall, then fix the connecting plate 11 on the back of the photovoltaic panel 1, and then hoist the photovoltaic panel 1 and the connecting plate 11 on its back to a position above the side of the two rotating rods 23. Then, as the photovoltaic panel 1 moves downward, insert the bending plates 12 on the connecting plate 11 into the corresponding bending grooves 2302 respectively to complete the installation of the photovoltaic panel 1. During the wiring process, by rotating the photovoltaic panel 1, the rotating rod 23 can rotate around the rotating shaft 22, which can conveniently rotate the photovoltaic panel 1 during wiring or maintenance, and more conveniently complete the wiring operation of the photovoltaic panel 1.

[0024] Furthermore, as Figure 4 , Figure 5 and Figure 6 shown, a through hole 2301 is arranged on the rotating rod 23, the middle of the through hole 2301 is communicated with the bending groove 2302, a limiting through hole 1201 corresponding to the through hole 2301 is arranged on the bending plate 12, and a limiting block 42 for passing through the through hole 2301 and the limiting through hole 1201 is arranged on the L-shaped rod 21.

[0025] Among them, after installing the photovoltaic panel 1 between the two L-shaped rods 21, by using the limiting block 42 to pass through the through hole 2301 and the limiting through hole 1201, multi-point support can be conveniently formed on the back of the photovoltaic panel 1, so that the photovoltaic panel 1 is more firmly installed on the side of the wall.

[0026] Furthermore, as Figure 5 and Figure 6As shown, the bent plate 12 includes a bent section fixedly connected to the connecting plate 11 and an arc section away from the connecting plate 11. The bent section and the arc section are of an integrally formed structure. The arc section is installed in an interference fit with the inside of the bent groove 2302. During the installation process, the arc section in interference fit can expand the bent groove 2302, enabling the bent plate 12 of the arc section part to fit more closely with the inner wall of the bent groove 2302. The bent plate 12 of the arc section part and the inner wall of the bent groove 2302 have a greater static friction force, making the position of the bent plate 12 inside the bent groove 2302 more stable.

[0027] Further, as Figure 7 and Figure 8 shown, it further includes a first sliding frame 3. The top view projection contour of the first sliding frame 3 is U-shaped. A scraping box 31 for scraping dust on the photovoltaic panel 1 is arranged on the first sliding frame 3. Linear motors are arranged at both ends of the first sliding frame 3. Guide rails for guiding the up and down movement of the linear motors are arranged on the L-shaped rod 21. A sliding groove is arranged on the scraping box 31. A scraping plate 33 is slidably installed inside the sliding groove. Elastic members 34 are arranged above and below the scraping plate 33. The other ends of the elastic members 34 are connected to the scraping box 31. The elastic members 34 are used to drive the scraping plate 33 to move towards the scraping box 31. Rotating shafts 331 are rotatably installed at both ends of the scraping plate 33.

[0028] Among them, by arranging the first sliding frame 3 on the outer side of the photovoltaic panel 1 and driving the first sliding frame 3 to be installed on the L-shaped rod 21 through a linear motor, when dust is deposited on the surface of the photovoltaic panel 1, the linear motor drives the first sliding frame 3 to move downward, enabling the scraping plate 33 to slide on the surface of the photovoltaic panel 1, and scraping the dust deposited on the surface of the photovoltaic panel 1 downward, facilitating the cleaning of the surface of the photovoltaic panel 1. In addition, one end of the scraping plate 33 close to the photovoltaic panel 1 is in an isosceles trapezoid shape, and a wiping rubber strip is wrapped around the end surface of the scraping plate 33 in contact with the surface of the photovoltaic panel 1.

[0029] Further, as Figure 7 and Figure 8 shown, a second sliding frame 4 is arranged below the first sliding frame 3. The second sliding frame 4 has the same structure as the first sliding frame 3. A limiting wedge 41 for driving the scraping plate 33 to move towards the photovoltaic panel 1 is arranged on the second sliding frame 4. When the second sliding frame 4 approaches the first sliding frame 3, the limiting wedge 41 drives the scraping plate 33 to approach the photovoltaic panel 1 by restricting the position of the rotating shaft 331.

[0030] Among them, by arranging a limiting wedge 41 on the second sliding frame 4, by adjusting the vertical distance between the second sliding frame 4 and the first sliding frame 3, the limiting wedge 41 can conveniently drive the scraping plate 33 to approach or move away from the surface of the photovoltaic panel 1, the dust scraping force on the photovoltaic panel 1 can be controlled, so that the first sliding frame 3 only scrapes and cleans the photovoltaic panel 1 during the downward movement, the scratches on the surface of the photovoltaic panel 1 can be reduced, and the dust on the scraping plate 33 during the upward movement can also be prevented from adhering to the surface of the photovoltaic panel 1 again.

[0031] Furthermore, a guiding frame 43 is fixedly installed on the second sliding frame 4. One end of the limiting block 42 away from the bending plate 12 is slidably installed inside the guiding frame 43. A return spring 431 for driving the limiting block 42 to move towards the guiding frame 43 is installed inside the guiding frame 43. A limiting inclined plate 421 is fixedly installed on the limiting block 42. An L-shaped limiting rod 32 for restricting the sliding position of the limiting inclined plate 421 is fixedly installed on the first sliding frame 3. The limiting inclined plate 421 includes a vertical section and a limiting section. The lower part of the limiting section inclines towards the guiding frame 43. When the limiting wedge 41 restricts the movement of the scraping plate 33 towards the photovoltaic panel 1, the lowermost part of the L-shaped limiting rod 32 reaches the vertical section.

[0032] Among them, by slidably installing the limiting block 42 on the second sliding frame 4, in windy weather, first drive the second sliding frame 4 to move upward to the middle of the photovoltaic panel 1, so that the limiting block 42 on the second sliding frame 4 is directly opposite to the through hole 2301. Then, by driving the first sliding frame 3 to move downward, the L-shaped limiting rod 32 on the first sliding frame 3 can be driven to move downward. When the lower end of the L-shaped limiting rod 32 abuts against the limiting section of the limiting inclined plate 421, as the L-shaped limiting rod 32 continues to move downward, the limiting block 42 moves towards the through hole 2301, and the limiting block 42 can pass through the through hole 2301 and the limiting through hole 1201, which can conveniently further fix the position of the bending plate 12 inside the bending groove 2302, and at the same time, the rotating rod 23 can be prevented from rotating in windy weather.

[0033] Furthermore, as Figure 1 and Figure 2 shown, both ends of the rotating shaft 22 pass through the two rotating rods 23 and are fixedly connected to the two rotating rods 23. The rotating shaft 22 connects the two rotating rods 23, so that the two rotating rods 23 rotate synchronously during the rotation process, which is more convenient to align with the bending plate 12 on the back of the photovoltaic panel 1. Both ends of the rotating shaft 22 are rotatably connected to the two L-shaped rods 21.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
