Description

Technical Field

[0001] This invention relates to the field of photovoltaic energy storage technology, and in particular to an energy storage device based on rooftop photovoltaic power generation in a science park factory. Background Technology

[0002] Building-integrated photovoltaics (BIPV) is a technology that combines solar power generation with buildings. By installing photovoltaic panels on buildings, solar energy is converted into electrical energy, enabling buildings to be self-sufficient or reducing their dependence on the traditional power grid. At the same time, this device can also store the electrical energy generated by the photovoltaic panels when it exceeds the immediate consumption of the building, and release it when needed.

[0003] In the prior art, in order to increase power generation, photovoltaic panels installed on the roofs of factories in science and technology parks are mostly densely distributed, such as the solution disclosed in the invention patent with authorization announcement number CN118547838B. However, the dense distribution method also results in insufficient maintenance channels between adjacent rows of photovoltaic panels, making subsequent maintenance inconvenient. At the same time, during heavy rain and snow in winter, rainwater is prone to freezing and snow accumulation on the surface of photovoltaic panels, which not only affects the service life of photovoltaic panels, but also makes it inconvenient to clean the ice and snow due to the lack of maintenance channels.

[0004] Therefore, it is necessary to invent an energy storage device based on rooftop photovoltaic power generation in science and technology park factories to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an energy storage device based on rooftop photovoltaic power generation in a science park. During maintenance, a maintenance channel can be formed above the photovoltaic power generation structure, facilitating dense installation while ensuring power generation and reducing maintenance difficulty. Furthermore, in rainy or snowy weather, it avoids the problems of rainwater or snow accumulation leading to difficult cleaning and shortened photovoltaic panel lifespan. This addresses the issues mentioned in the background art, where the dense distribution method results in insufficiently wide maintenance channels between adjacent rows of photovoltaic panels, making subsequent maintenance inconvenient. Additionally, in winter, heavy rain and snow can easily cause rainwater to freeze and snow to accumulate on the photovoltaic panel surface, affecting not only the lifespan of the panels but also making cleaning of ice and snow difficult due to the lack of maintenance channels.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an energy storage device based on rooftop photovoltaic power generation in a science park factory, comprising an energy storage mechanism, a first covering mechanism disposed above the energy storage mechanism, two sets of symmetrically arranged second covering mechanisms disposed inside the energy storage mechanism and at the bottom of the first covering mechanism, extension mechanisms disposed on the top of both sides of the energy storage mechanism, photovoltaic power generation mechanisms disposed on the bottom of both sides of the energy storage mechanism, and a traction and pushing mechanism disposed inside the energy storage mechanism and at the middle of the side of the energy storage mechanism; Each of the second covering mechanisms includes a winding shaft nested inside the base housing via a bearing. Gears and torsion springs are sequentially sleeved at both ends of the outer side of the winding shaft from the inside out. The gears are fixedly connected to the winding shaft, and the torsion springs are fixedly connected between the gears and the inner wall of the base housing. A waterproof curtain is wound around the middle of the outer side of the winding shaft. The bottom end of the waterproof curtain is fixedly connected to the outer wall of the winding shaft. The top end of the waterproof curtain passes through adjacent clearance channels and around two adjacent guide rollers and is fixedly connected to a counterweight rod. The counterweight rod is attached to the side of two adjacent fixed plates.

[0007] Preferably, the energy storage mechanism includes a base box, with clearance passages on both sides of the top of the base box, and an energy storage cabinet is fixedly installed at the center of the top of the base box.

[0008] Preferably, the first covering mechanism includes a top cover located directly above the energy storage cabinet and fixedly mounted on the top of the four connecting blocks A. Two fixing plates are fixedly mounted on both sides of the bottom of the top cover, and two parallel guide rollers are rotatably nested between two adjacent fixing plates on the same side via bearings.

[0009] Preferably, any set of the extension mechanisms includes a connecting spring A fixedly connected to the side of the base box. A push plate is fixedly connected to the end of the connecting spring A. Both ends of the push plate near the base box are fixedly provided with racks. Both racks slide through the side wall of the base box and extend into the interior of the base box.

[0010] Preferably, any group of the photovoltaic power generation mechanisms includes a U-shaped frame located on the side of the base box, and a barrier bar is fixedly installed on the inner side of the U-shaped frame near the end of the base box.

[0011] Preferably, both ends of the U-shaped frame are fixedly connected to guide sleeves, and both guide sleeves are fixedly provided with the side of the base box. Lifting rods are slidably provided on the inner side of the two guide sleeves in the vertical direction.

[0012] Preferably, each of the two lifting rods has a connecting block A fixedly installed at its top end, and the two connecting blocks A are rotatably connected by a pin shaft to a fixed frame. Two connecting blocks B are fixedly installed at the end of the fixed frame away from the base box, and multiple photovoltaic panels are fixedly installed inside the fixed frame. All of the photovoltaic panels are electrically connected to the energy storage cabinet.

[0013] Preferably, any one of the traction and pushing mechanisms includes a lead screw that is rotatably nested in the middle of the side of the base box via a bearing and a servo motor that is fixedly installed inside the base box. The lead screw is connected to the servo motor for transmission, and guide shafts that are parallel to each other and fixedly connected to the side wall of the base box are provided on both sides of the lead screw.

[0014] Preferably, a push-pull plate, a connecting spring B, and a moving plate are sleeved together on the outer sides of the two guide shafts from the inside to the outside. The push-pull plate and the moving plate are slidably connected to the guide shafts. The push-pull plate is driven and sleeved on the outer side of the lead screw. The connecting spring B is fixedly connected between the push-pull plate and the moving plate. The moving plate is rotatably connected to two adjacent connecting blocks B through a pin and is slidably sleeved on the outer side of the lead screw.

[0015] The technical effects and advantages of this invention are as follows: This invention incorporates a second covering mechanism and a photovoltaic power generation mechanism. During maintenance, the photovoltaic power generation mechanism can be retracted using a traction and pushing mechanism, creating a maintenance channel above it. This facilitates dense installation, ensuring power generation while reducing maintenance difficulty. In rainy or snowy weather, the traction and pushing mechanism, after driving the photovoltaic power generation mechanism, can continue to drive the extension mechanism. This allows the extension mechanism to work with the first covering mechanism to extend the second covering mechanism a second time. The second covering mechanism then shields multiple photovoltaic panels from the outside, preventing rainwater or snow accumulation that would make cleaning difficult and shorten the lifespan of the photovoltaic panels.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] This invention provides, for example Figures 1-5 The energy storage device shown is based on a rooftop photovoltaic power generation system in a science park factory. It includes an energy storage mechanism 1, a first covering mechanism 2 located directly above the energy storage mechanism 1, two sets of symmetrically arranged second covering mechanisms 3 located inside the energy storage mechanism 1 and at the bottom of the first covering mechanism 2, extension mechanisms 4 located at the top of both sides of the energy storage mechanism 1, photovoltaic power generation mechanisms 5 located at the bottom of both sides of the energy storage mechanism 1, and a traction and pushing mechanism 6 located inside the energy storage mechanism 1 and at the middle of the side of the energy storage mechanism 1.

[0020] like Figure 2 As shown, the energy storage mechanism 1 includes a base box 11, which is welded from Q235B galvanized steel plate. It is resistant to atmospheric corrosion and has high mechanical strength. Both sides of the top of the base box 11 are provided with clearance passages 12, and an energy storage cabinet 13 is fixedly installed at the center of the top of the base box 11.

[0021] By setting up the above structure, multiple units of this device can be densely installed on the roof of a factory building in a science and technology park when it is actually used. After installation, under normal working conditions with no maintenance required and clear weather, the device is in a fully deployed state. Multiple photovoltaic panels 58 maximize the reception of solar energy and convert it into DC power. After adjustment, part of the DC power is directly stored in the energy storage cabinet 13, and the other part is sent to the inverter to be converted into AC power for use by households or industrial loads.

[0022] like Figure 2 and Figure 3As shown, the first covering mechanism 2 includes a top cover 21 located directly above the energy storage cabinet 13 and fixedly mounted on the top of the four connecting blocks A55. The top cover 21 is made of 6061 aluminum alloy profile and is anodized, making it lighter and reducing the load on the factory. It is also resistant to ultraviolet aging and has excellent rainproof performance. Two fixing plates 22 are fixedly mounted on both sides of the bottom of the top cover 21. Two parallel guide rollers 23 are nested between two adjacent fixing plates 22 on the same side through a bearing. The outer layer has a nylon layer, which is wear-resistant and has a low coefficient of friction, reducing the wear of the waterproof curtain 34.

[0023] like Figure 3 As shown, any set of second covering mechanisms 3 includes a winding shaft 31 nested inside the base housing 11 via bearings. The shaft is made of 45# steel with a galvanized surface, exhibiting high torsional strength and rust resistance, and can withstand the winding torque of the waterproof curtain 34. Gears 32 and torsion springs 33 are sequentially sleeved at both ends of the outer side of the winding shaft 31 from the inside out. The torsion springs 33 are made of 60Si2Mn spring steel, exhibiting high elastic limit and long fatigue life, providing a restoring force for the contraction of the waterproof curtain 34. The gears 32 are fixedly connected to the winding shaft 31, and the torsion springs 33 are fixedly connected to the gears 32 and the base housing 11. Between the inner walls, a waterproof curtain 34 is wound around the middle of the outer side of the winding shaft 31. The material is PVC coated polyester fiber cloth, which is IPX7 waterproof, has high tensile strength and low temperature resistance, and can be repeatedly stretched and contracted. The bottom end of the waterproof curtain 34 is fixedly connected to the outer wall of the winding shaft 31. The top end of the waterproof curtain 34 passes through the adjacent avoidance channel 12 and goes around two adjacent guide rollers 23 and is fixedly connected to a counterweight rod 35. The counterweight rod 35 is attached to the side of two adjacent fixing plates 22. The counterweight rod 35 is a 304 stainless steel round tube filled with concrete inside. The weight is even, which ensures that the waterproof curtain 34 hangs flat and prevents rain and snow from seeping in.

[0024] By setting up the first covering mechanism 2 and the second covering mechanism 3, the top cover 21 is continuously moved upward during the process of the four connecting blocks A55 rising, so that the top cover 21 gradually moves away from the ground of the factory roof, so that there is enough space between the top cover 21 and the ground to accommodate the fixed frame 56. At the same time, when the top cover 21 moves upward, the two counterweight rods 35 are pulled by the four fixed plates 22, so that the two counterweight rods 35 pull the two waterproof curtains 34 respectively, so that the waterproof curtain 34 wound on the outer middle of the winding shaft 31 is pulled out through the avoidance channel 12, so as to realize the first extension of the waterproof curtain 34.

[0025] like Figure 3As shown, any set of extension mechanisms 4 includes a connecting spring A41 fixedly connected to the side of the base box 11. The spring A41 is made of 50CrVA spring steel, which has good elastic recovery and provides a restoring force for the push plate 42. The end of the connecting spring A41 is fixedly connected to the push plate 42, which is made of 6061 aluminum alloy and has a rubber buffer pad bonded on it. It is lightweight, rust-proof, and reduces impact noise and wear. Both ends of the push plate 42 near the base box 11 are fixedly provided with racks 43. Both racks 43 slide through the side wall of the base box 11 and extend into the interior of the base box 11.

[0026] By setting the above structure, after the push plate 42 is pushed, the push plate 42 compresses the connecting spring A41 and pushes the rack 43 to mesh with the gear 32. After meshing, as the rack 43 continues to move, the rack 43 drives the winding shaft 31 to rotate through the gear 32, thereby causing the winding shaft 31 to extend the waterproof curtain 34 for the second time. At this time, under the guidance of the two guide rollers 23 and the traction of the counterweight rod 35, the counterweight rod 35 drives the end of the waterproof curtain 34 to move continuously downward, finally achieving the shading of multiple photovoltaic panels 58 on the fixed frame 56.

[0027] like Figure 4 As shown, any set of photovoltaic power generation mechanisms 5 includes a U-shaped frame 51 located on the side of the base box 11. A blocking rod 52 is fixedly installed on the inner side of the U-shaped frame 51 near the base box 11. Guide sleeves 53, made of 6061 aluminum alloy, are fixedly connected to both ends of the U-shaped frame 51. These sleeves have smooth inner walls, small clearance with the lifting rod 54, and smooth sliding without deviation. Both guide sleeves 53 are fixedly installed on the side of the base box 11. The lifting rod 54, made of 6061 aluminum alloy, slides vertically along the inner side of both guide sleeves 53. The 6061 aluminum alloy round tube is lightweight and has high compressive strength. The top of each of the two lifting rods 54 is fixedly equipped with a connecting block A55. The two connecting blocks A55 are rotatably connected by a pin shaft to a fixed frame 56, which is formed by splicing 6061 aluminum alloy profiles. It has good rigidity and is lightweight, which can reduce the load on the lifting rods 54. Two connecting blocks B57 are fixedly installed at the end of the fixed frame 56 away from the base box 11. Multiple photovoltaic panels 58 are fixedly installed inside the fixed frame 56, and all of the photovoltaic panels 58 are electrically connected to the energy storage cabinet 13.

[0028] By setting up the above structure, after the bottom end of the fixed frame 56 is pushed towards the base box 11, the top end of the fixed frame 56 drives the two lifting rods 54 to move continuously upward inside the two guide sleeves 53 through the two connecting blocks A55, thereby enabling the fixed frame 56 to store the photovoltaic panel 58.

[0029] like Figure 5As shown, any set of traction and pushing mechanisms 6 includes a lead screw 61 nested in the middle of the side of the base box 11 via a bearing and a servo motor 62 fixedly installed inside the base box 11. The lead screw 61 and the servo motor 62 are connected in transmission. Guide shafts 63 are provided on both sides of the lead screw 61, which are parallel to each other and fixedly connected to the side wall of the base box 11. A push-pull plate 64, a connecting spring B65 and a moving plate 66 are sleeved on the outer side of the two guide shafts 63 from the inside to the outside. The push-pull plate 64 and the moving plate 66 are slidably connected to the guide shafts 63. The push-pull plate 64 is connected in transmission to the outer side of the lead screw 61. The connecting spring B65 is fixedly connected between the push-pull plate 64 and the moving plate 66 and is made of 50CrVA spring steel. It has a stable elastic modulus, is fatigue resistant, and can buffer the force between the push-pull plate 64 and the moving plate 66. The moving plate 66 is rotatably connected to two adjacent connecting blocks B57 via a pin and is slidably sleeved on the outer side of the lead screw 61.

[0030] By setting up the above structure, when the maintenance passage needs to be cleared for maintenance of this device, the corresponding servo motor 62 is started. After the servo motor 62 starts, it drives the lead screw 61 to rotate continuously, which in turn drives the push-pull plate 64, guided by the guide shaft 63, to move closer to the servo motor 62. During this process, the push-pull plate 64 pulls the moving plate 66 through the connecting spring B65, so that the moving plate 66 moves closer to the servo motor 62 synchronously. At this time, the moving plate 66 pushes the bottom end of the fixed frame 56 through the connecting block B57 to realize the storage of the photovoltaic power generation mechanism 5. After the photovoltaic power generation mechanism 5 is stored, that is, when the moving plate 66 is attached to the side of the barrier bar 52, the barrier... The barrier 52 blocks the moving plate 66, preventing it from moving further inward. At the same time, the fixed frame 56 drives multiple photovoltaic panels 58 to be stored. The space cleared by the moving and storage of the fixed frame 56 can be used as a maintenance passage for maintenance personnel. If maintenance is only required, the servo motor 62 is stopped. If multiple photovoltaic panels 58 are being stored in rainy or snowy weather to prevent ice or snow from forming on their surfaces, the servo motor 62 is not stopped. Subsequently, as the push-pull plate 64 continues to move inward, the connecting spring B65 is continuously stretched, and the push-pull plate 64 pushes the adjacent pushed plate 42.

[0031] Working principle: In practical applications, multiple units of this device are densely installed on the roof of a factory building in a science and technology park. After installation, multiple photovoltaic panels 58 collect solar energy and convert it into DC power. After adjustment, part of the DC power is directly stored in the energy storage cabinet 13, and the other part is sent to the inverter to be converted into AC power for use by households or industrial loads. When the maintenance channel needs to be cleared for maintenance of this device, the corresponding servo motor 62 is started. After the servo motor 62 is started, it drives the lead screw 61 to rotate continuously, which in turn drives the push-pull plate 64, which is guided by the guide shaft 63, to move closer to the servo motor 62. During this process, the push-pull plate 64 pulls the moving plate 66 through the connecting spring B65, so that the moving plate 66 moves closer to the servo motor 62 in sync. At this time, the moving plate 66 pushes the bottom of the fixed frame 56 through the connecting block B57, and the top of the fixed frame 56 drives the two lifting rods 54 to move continuously upward inside the two guide sleeves 53 through the two connecting blocks A55, so that the fixed frame 56 can store the photovoltaic panel 58. As the four connecting blocks A55 rise, they drive the top cover 21 to move upward continuously, thereby gradually moving the top cover 21 away from the ground at the top of the factory building, so that there is enough space between the top cover 21 and the ground to accommodate the fixed frame 56. At the same time, as the top cover 21 moves upward, it pulls the two counterweight rods 35 through the four fixed plates 22, thereby causing the two counterweight rods 35 to pull the two waterproof curtains 34 respectively, so that the waterproof curtain 34, which is wound around the middle of the outer side of the winding shaft 31, is pulled out through the avoidance channel 12 to achieve the first extension of the waterproof curtain 34. When the movable plate 66 is attached to the side of the barrier bar 52, the barrier bar 52 blocks the movable plate 66. At this time, the movable plate 66 cannot move further inward. At the same time, the fixed frame 56 drives multiple photovoltaic panels 58 to complete the storage. At this time, the space cleared by the fixed frame 56 moving and storing the U-shaped frame 51 can be used as a maintenance passage for maintenance personnel. If only maintenance is required, the servo motor 62 will be stopped at this time. If multiple photovoltaic panels 58 are to be stored during rainy or snowy weather to prevent ice or snow accumulation on their surfaces, the servo motor 62 will not be stopped. Subsequently, as the push-pull plate 64 continues to move inward, the connecting spring B65 is continuously stretched. At the same time, the push-pull plate 64 pushes the adjacent push plate 42. At this time, the push plate 42 compresses the connecting spring A41 and pushes the rack 43 to mesh with the gear 32. After meshing, as the rack 43 continues to move, the rack 43 drives the winding shaft 31 to rotate through the gear 32, thereby causing the winding shaft 31 to extend the waterproof curtain 34 for the second time. At this time, under the guidance of the two guide rollers 23 and the traction of the counterweight rod 35, the counterweight rod 35 drives the end of the waterproof curtain 34 to move continuously downward, ultimately achieving the shading of multiple photovoltaic panels 58 on the fixed frame 56. At this time, the servo motor 62 will be stopped.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
