Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cover technology, specifically to a molded assembly photovoltaic fiberglass arc cover. Background Technology

[0002] Photovoltaic fiberglass curved covers are composite material covers widely used in photovoltaic power plants and other fields. They are typically made of glass fiber and resin through molding or pultrusion processes. Due to their excellent properties such as light weight, high strength, corrosion resistance, and good weather resistance, photovoltaic fiberglass curved covers are often used in photovoltaic module backsheets, cable trough covers, and other parts to protect internal electrical equipment, cables, and connectors.

[0003] Existing photovoltaic fiberglass curved covers are typically curved structures. This design not only effectively disperses external loads (such as wind pressure and snow pressure) but also improves the sealing performance of the cover, preventing rainwater, dust, and clothing from entering the equipment.

[0004] However, photovoltaic modules generate a lot of heat when they are working, and the sealed cover structure prevents the heat from dissipating, causing the internal temperature of the equipment to rise (because the power generation efficiency of photovoltaic modules will decrease by about 0.4%-0.5% for every 1°C increase in the operating temperature of the photovoltaic module). This will reduce the power generation efficiency of the photovoltaic modules when they are working, and the photovoltaic modules will not only have a shorter lifespan when they are working in a high-temperature environment, but the heat accumulation may also cause the equipment to overheat or even catch fire. Utility Model Content

[0005] In view of this, the present invention provides a molded assembly photovoltaic fiberglass arc cover plate, which can be adjusted in position according to different usage environments by using a mounting plate and a symmetrically arranged sealing component on the upper part. This can maintain its sealing performance, avoid reducing power generation efficiency due to excessive internal temperature, and extend the service life of photovoltaic modules.

[0006] To solve the above technical problems, this utility model provides a molded assembled photovoltaic fiberglass arc cover plate, including an installation plate. The installation plate is set as an arc structure and has an installation groove through it. The installation groove can be opened by a cutting machine during the manufacturing process. Two sets of sealing components are symmetrically arranged on the upper part of the installation plate. The two sets of sealing components can protect the photovoltaic module in severe weather such as rain or snow, and can be opened in sunny or hot weather to dissipate heat from the internal photovoltaic module.

[0007] Each sealing assembly includes a support plate located on one side of the upper part of the mounting plate. The support plate is fixedly connected to the upper part of the mounting plate, and the number of support plates is set to at least one. Each support plate has a damping shaft on its upper part. The fixed frame of the damping shaft is bolted to the upper part of the support plate, and the movable frame of each damping shaft is connected to one end of the cover plate body. The movable frame of the damping shaft is bolted to one end of the cover plate body, which is a photovoltaic fiberglass arc cover plate.

[0008] Each cover plate body has multiple fixing slots on its upper part. These fixing slots can be integrally formed with the cover plate body during manufacturing through a molding process. The inner sidewalls of the multiple fixing slots are connected to heat dissipation columns, which are also integrally formed using a molding process. The heat dissipation columns can be made of materials with high thermal conductivity, such as aluminum alloy, copper, or carbon fiber composite materials.

[0009] All heat dissipation columns are hollow structures, and the heat dissipation columns and their hollow structures can be integrally formed by molding.

[0010] An insect-proof net is attached to the mounting slot.

[0011] The insect-proof net is connected to the inner wall of the installation groove by a fixing frame. The insect-proof net is fixed to the inner wall of the installation groove by a solvent bonding method. The fixing frame is connected to the inner wall of the installation groove by bolts.

[0012] A first sealing gasket is provided on the upper part of the mounting plate and is fixedly connected to the upper part of the mounting plate. A second sealing gasket is provided on the facing surfaces of the two cover plates and is fixedly connected to the facing surfaces of the two cover plates.

[0013] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0014] 1. By using the mounting plate and the symmetrically arranged sealing components on top, the position of the two cover plates can be adjusted according to different usage environments. This not only maintains the airtightness but also prevents the power generation efficiency from being reduced due to excessive internal temperature and extends the service life of the photovoltaic module.

[0015] 2. By setting heat dissipation columns, the heat-receiving area can be increased, thereby further improving the heat dissipation effect after the cover plate is closed.

[0016] 3. By using a fixed frame and insect-proof net, when the two cover plates are opened for heat dissipation, insects, leaves and other debris are prevented from falling into the photovoltaic modules. This prevents the photovoltaic modules from being affected by debris falling in, further improving the safety of the photovoltaic modules during heat dissipation and preventing damage to the photovoltaic modules caused by external factors.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the appendices of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0026] like Figure 1 , 3 As shown: A molded assembled photovoltaic fiberglass arc-shaped cover includes a mounting plate 101. The mounting plate 101 provides stable support for the various components on it, and the mounting plate 101 and its components can be bolted to the required positions, thereby providing precise protection for the photovoltaic modules in the corresponding positions. The mounting plate 101 is designed with an arc shape and has a through-hole mounting groove. The mounting groove allows heat to dissipate through it and provides stable support for the insect net 302 and its components. The mounting groove can be cut into the mounting plate 101 during manufacturing using a cutting machine, making the manufacturing process more convenient and the connection structure of the mounting groove more stable. Two sets of sealing components are symmetrically arranged on the upper part of the mounting plate 101. The two sets of sealing components can protect the photovoltaic modules in severe weather such as rain or snow, and can be opened in sunny or hot weather to allow the internal photovoltaic modules to dissipate heat.

[0027] like Figure 1 , 2 As shown: Each sealing assembly includes a support plate 103 disposed on one side of the upper part of the mounting plate 101. The support plate 103 provides stable support for the damping shaft 104 disposed on it, and also provides stable support for the various components thereon. The support plate 103 is fixedly connected to one side of the upper part of the mounting plate 101, thereby making the connection structure more stable and further improving the overall stability of the structure. The number of support plates 103 is set to at least one, so that the number of damping shafts 104 can be increased as the number of support plates 103 increases, and thus can be adjusted according to the cover plate body 102. The weight of the damping shafts 104 is adjusted to improve the support structure and stability of the cover plate body 102 during adjustment. Each support plate 103 is equipped with a damping shaft 104. The damping shaft 104 allows the cover plate body 102 connected to it to be adjusted to any position and then fixed after being adjusted to a suitable position, further improving the convenience of adjustment. It can also be opened and fixed when heat dissipation of photovoltaic modules is required. Therefore, heat dissipation of photovoltaic modules can be carried out in sunny weather and other environments, and it is easy to operate.

[0028] like Figure 1 , 2 As shown: The fixing frame of the damping shaft 104 is bolted to the upper part of the support plate 103, so that the damping shaft 104 can be stably supported and can be easily disassembled and installed when maintenance or replacement is required. The movable frame of each damping shaft 104 is connected to one end of the cover plate body 102, so that the cover plate body 102 can be limited when it needs to be opened or closed, and the cover plate body 102 can be fixed by the damping shaft 104 when it needs to be opened. The movable frame of the damping shaft 104 is bolted to one end of the cover plate body 102, so that the cover plate body 102 and the damping shaft 104 can be easily disassembled and installed when maintenance or replacement is required. The cover plate body 102 is a photovoltaic fiberglass arc cover plate, which can improve the protective effect of the cover plate body 102 on the photovoltaic module.

[0029] like Figure 4As shown: Each cover plate body 102 has multiple fixing slots on its upper part. These slots provide stable support for the heat dissipation columns 201. The fixing slots are integrally formed with the cover plate body 102 during manufacturing using a molding process, resulting in a more stable connection structure and easier manufacturing. Heat dissipation columns 201 are connected to the inner walls of each fixing slot. The heat dissipation columns 201 increase the heat-receiving area, further improving the heat dissipation effect after the cover plate body 102 is closed. The heat dissipation columns 201 are also integrally formed using a molding process, allowing for stable support. To facilitate manufacturing, the heat dissipation column 201 can be made of materials with high thermal conductivity, such as aluminum alloy, copper, or carbon fiber composite material, thereby improving the heat dissipation effect of the heat dissipation column 201. Appropriate materials can be selected according to the manufacturing cost. All heat dissipation columns 201 are made into hollow structures, which can reduce the overall weight and improve the heat dissipation effect by controlling the thickness of the heat dissipation column 201. Multiple heat dissipation columns 201 and their hollow structures can be integrally formed by molding process, thereby making their connection structure more stable and easy to manufacture.

[0030] like Figure 3 , 4 As shown: An insect-proof net 302 is connected to the mounting slot. The insect-proof net 302 prevents insects, leaves, and other debris from falling into the photovoltaic module when the two cover plates 102 are opened for heat dissipation, thus avoiding damage to the photovoltaic module caused by debris. This further enhances the safety of the photovoltaic module during heat dissipation and prevents damage caused by external factors. The insect-proof net 302 is connected to the inner wall of the mounting slot via a fixing frame 301, allowing for easy disassembly and replacement when cleaning or replacement is needed, further improving convenience. The insect-proof net 302 is fixed to the inner wall of the mounting slot using a solvent adhesive connection, making its connection structure more stable. The fixing frame 301 is bolted to the inner wall of the mounting slot, facilitating disassembly and replacement of the fixing frame 301 and the connected insect-proof net 302 when maintenance or replacement is required. The fixing frame 301 not only provides support for the insect-proof net 302 but also facilitates its disassembly and assembly.

[0031] like Figure 4As shown: A first sealing gasket 401 is provided on the upper part of the mounting plate 101. The first sealing gasket 401 can further improve the sealing of the two cover plate bodies 102 when they are lowered, thereby improving their waterproof effect. The first sealing gasket 401 is fixedly connected to the upper part of the mounting plate 101, thereby making the connection structure more stable. A second sealing gasket is provided on the facing surfaces of the two cover plate bodies 102. The second sealing gasket can make the two cover plate bodies 102 close more tightly when closed, thereby further improving the overall sealing performance. The second sealing gasket is fixedly connected to the facing surfaces of the two cover plate bodies 102, thereby making the connection structure more stable. Both the first sealing gasket 401 and the second sealing gasket can be made of rubber, which can save costs and increase the friction of the second sealing gasket. Furthermore, the deformation of the second sealing gasket can make the two cover plate bodies 102 close more tightly.

[0032] In use, multiple mounting plates 101 and their components are sequentially installed in their corresponding positions using bolts. In harsh environments (such as rain or snow), the two cover plates 102 can be closed by holding them, thus blocking rain and snow and preventing damage to the internal photovoltaic modules. When ventilation of the internal photovoltaic modules is needed in sunny or rainless environments, the two cover plates 102 can be opened and adjusted to the appropriate position using the damping pivot 104. Therefore, the airtightness can be maintained, the power generation efficiency can be prevented from being reduced due to excessive internal temperature, the service life of the photovoltaic modules can be extended, and accidents can be avoided. Furthermore, when adjusting the cover plates 102, the position of the cover plates should be adjusted according to the location of the sun to prevent direct sunlight from hitting the photovoltaic modules and causing their temperature to rise.

[0033] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0034] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
