Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic power stations, and in particular relates to a photovoltaic building integrated power station with a rapid snow removal function. Background Art

[0002] As a highly innovative new energy system, building-integrated photovoltaic (BIPV) power stations cleverly integrate solar photovoltaic (PV) modules with building structures, enabling them to simultaneously perform the dual functions of power generation and building protection. This unique design breaks the boundaries between traditional energy utilization and building functions, paving a new path for the integrated development of the construction and energy sectors. This system primarily utilizes PV modules as building materials, applying them to roofs, walls, and other building surfaces. This effectively reduces a building's reliance on external energy sources, achieving self-sufficiency in energy consumption. Furthermore, it enables large-scale green energy production, providing society with clean, sustainable electricity resources, achieving the dual goals of building energy self-sufficiency and green energy production. Because of these significant advantages, BIPV power stations are widely used in a wide range of applications, including residential, commercial, and public facilities. In residential buildings, it can provide daily electricity for households, reducing residents' electricity costs. In commercial buildings, it can partially meet the power needs of shopping malls, office buildings, and other places, reducing business operating costs. In public facilities such as schools and hospitals, it can provide stable energy support for the normal operation of public services. In snowy areas, to ensure continuous and efficient power generation from photovoltaic panels, snow removal technologies such as thermal snow removal (using heating wires and waste heat to melt snow), mechanical snow removal (vibration shaking and push-plate snow removal), and passive snow removal (optimizing the building's inclination angle) are often used.

[0003] Currently, mechanical push-plate snow removal mechanisms are widely used in photovoltaic building-integrated power plants due to their simple structure and low cost. However, this mechanism has a significant drawback in actual operation: during snow removal, as the push plate moves forward, snow accumulates at the front of the push plate. When the snow accumulates to a certain height, some of the snow, due to the push plate's inertia and gravity, flows over the top of the push plate and falls back onto the surface of the photovoltaic panels that have already been cleared, resulting in incomplete snow removal. Summary of the Invention

[0004] The purpose of the present invention is to provide a photovoltaic building integrated power station with a rapid snow removal function. By arranging a rotatable push plate in the snow removal component and utilizing the cooperation between the pin shaft and the corrugated protrusion of the control plate to drive the push plate to discharge the snow accumulated at the front end of the Z-shaped scraper to both sides, the problem of the existing mechanical push plate snow removal mechanism that snow is easily accumulated and overturned to the surface of the cleared photovoltaic panels during snow removal, resulting in incomplete snow removal, is solved.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions: The present invention is a photovoltaic building integrated power station with a rapid snow removal function, comprising photovoltaic panels, V-groove profiles fixedly installed on both sides of the photovoltaic panels, pulleys slidably installed on the two V-groove profiles, and a snow removal component fixedly installed on the two pulleys. The snow removal component includes a Z-shaped scraper fixedly installed on the two pulleys, a rubber scraper fixedly connected to the bottom of the Z-shaped scraper, and two symmetrical groups of push plates rotatably matched on one side of the Z-shaped scraper, and each group of push plates is arranged in a linear array.

[0006] The present invention is further configured such that the hinged end of the push plate is hinged to the Z-shaped scraper, and a shift block is fixedly connected to the hinged end of the push plate, and the shift block passes through the Z-shaped scraper.

[0007] The present invention is further configured such that two symmetrical trapezoidal slides are slidably fitted on the other side of the Z-shaped scraper, and a plurality of connecting grooves are provided in a linear array on the side of the trapezoidal slide close to the Z-shaped scraper, the end of the shift block is embedded in the connecting groove, and one end face of the trapezoidal slide is inclined.

[0008] The present invention is further configured such that two pins are slidably fitted through the bottom of the Z-shaped scraper, and one end of the pin is in contact with the inclined end surface of the trapezoidal slide.

[0009] The present invention is further configured such that a control plate is fixedly mounted on both of the V-groove profiles, a plurality of corrugated protrusions are evenly spaced along the length of the upper surface of the control plate, and the other end of the pin shaft contacts the upper contour surface of the control plate.

[0010] The present invention is further configured such that the other end of the trapezoidal slide is fixedly connected to a pressure rod, the other side of the Z-shaped scraper is fixedly connected to a limit plate, both sides of the limit plate are fixedly connected to a sleeve, the sleeve is slidably fitted with the pressure rod, and one end of the pressure rod is provided with a spring located in the sleeve.

[0012] The present invention has the following beneficial effects: The present invention realizes the scraping of snow on the surface of photovoltaic panels by cooperating with a Z-shaped scraper and a rubber scraper. At the same time, the cooperation between the pin shaft and the corrugated protrusion of the control plate is used to drive the trapezoidal slide to drive the shift block to rotate the push plate, thereby pushing the snow accumulated at the front end of the Z-shaped scraper to both sides, effectively preventing the snow from rolling over to the surface of the cleared photovoltaic panels. Compared with the traditional mechanical push-plate snow removal mechanism, the thoroughness of snow removal is significantly improved, so that the photovoltaic panels can still maintain a high power generation efficiency in snowy weather, and the snow removal efficiency is significantly improved.

[0019] Specifically, the snow removal assembly 3 includes a Z-shaped scraper 5 fixedly mounted on two pulleys 4, a rubber scraper 19 fixedly connected to the bottom of the Z-shaped scraper 5, and two symmetrical push plates 6 are rotatably matched on one side of the Z-shaped scraper 5, each push plate 6 is arranged in a linear array, wherein, when the pulley 4 rolls in the V-groove profile 2 through the roller, it will drive the Z-shaped scraper 5 to move synchronously, and the Z-shaped scraper 5 cooperates with the rubber scraper 19 at the bottom to scrape the snow on the surface of the photovoltaic panel 1; the rubber scraper 19 is in close contact with the surface of the photovoltaic panel 1, so as to better scrape off the residual snow and avoid the hard scraper from damaging the panel surface. The rotatable push plate 6 can push the snow to both sides to prevent the snow from accumulating in front of the Z-shaped scraper 5 and climbing over the Z-shaped scraper 5; The hinged end of the push plate 6 is hinged to the Z-shaped scraper 5, and a shift block 7 is fixedly connected to the hinged end of the push plate 6. The shift block 7 passes through the Z-shaped scraper 5. Two symmetrical trapezoidal slides 8 are slidably fitted on the other side of the Z-shaped scraper 5. The trapezoidal slides 8 are provided with a plurality of connecting grooves 9 in a linear array on the side close to the Z-shaped scraper 5. The end of the shift block 7 is embedded in the connecting groove 9. The size of the connecting groove 9 should be larger than that of the shift block 7, so that the shift block 7 can be moved laterally by the trapezoidal slides 8 to drive the push plate 6 to swing. One end face of the trapezoidal slide 8 is inclined, and the bottom of the Z-shaped scraper 5 passes through two pins 10 that slide and fit together. One end of the pin 10 contacts the inclined end face of the trapezoidal slide 8. A control plate 11 is fixedly mounted on each of the two V-groove profiles 2. A plurality of corrugated protrusions are arranged on the upper surface of the control plate 11 at equal intervals along its length. The other end of the pin 10 contacts the upper contour surface of the control plate 11. The pin 10 passes through the bottom of the Z-shaped scraper 5, and its two ends contact the inclined end face of the trapezoidal slide 8 and the corrugated protrusion of the control plate 11 respectively. The pin 10 is forced to move up and down through the upper contour surface of the control plate 11. When the pin 10 moves up, it squeezes the inclined end face of the trapezoidal slide 8, driving the trapezoidal slide 8 to move laterally.

One end of the pressure rod 15 is fixed to the trapezoidal slide 8, and the other end passes through the sleeve 17 and abuts against the spring 18. When the pin shaft 10 moves upward and drives the trapezoidal slide 8 to move horizontally, the trapezoidal slide 8 will drive the pressure rod 15 to compress the spring 18, and when the pin shaft 10 moves downward, the spring 18 is reset to push the pressure rod 15, causing the trapezoidal slide 8 to move in the opposite direction.

[0020] Furthermore, pulleys 12 are fixedly installed at both ends of the V-groove profile 2, and a transmission belt 13 is commonly sleeved on the side surfaces of the two pulleys 12. A connecting clamp 14 is fixedly installed on the transmission belt 13, and the connecting clamp 14 is fixedly connected to the pulley 4. The pulley 12 is driven to rotate by an external motor, and the connecting clamp 14 and the pulley 4 are driven by the transmission belt 13 to move along the V-groove profile 2, thereby realizing the reciprocating motion of the snow removal component 3.

[0021] The operation process of this embodiment is as follows: the pulley 12 is driven by the external motor to rotate, driving the transmission belt 13 to make the connecting clamp 14 and the pulley block 4 move along the V-groove profile 2, and the pulley block 4 drives the Z-shaped scraper 5 to move synchronously, and the rubber scraper 19 at the bottom of the Z-shaped scraper 5 is close to the surface of the photovoltaic panel 1 to scrape the snow. At the same time, when the Z-shaped scraper 5 moves, it drives the pin shaft 10 to slide up and down on the corrugated convex contour surface of the control plate 11
