Description

Technical Field

[0001] This utility model belongs to the field of explosion-proof technology, specifically relating to an explosion relief plate with insulation cotton that can be installed on the top and side. Background Technology

[0002] With the rapid development of energy storage technology, energy storage cabinets have been widely used in the new energy field. During the operation of energy storage cabinets, excessive pressure and heat may be generated inside due to reasons such as battery thermal runaway. In order to ensure the safe operation of energy storage cabinets, it is necessary to install explosion relief plates.

[0003] Existing explosion relief panels are installed inside energy storage cabinets. Due to thermal runaway of the battery pack inside the energy storage cabinet, explosions and deflagrations may occur inside the cabinet. Most explosion relief panels on the market have an upper insulation structure, resulting in a lack of insulation at the connection points. Furthermore, existing explosion relief panels are only suitable for top installation and not for side installation in energy storage cabinets. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: providing a pressure relief plate with insulation cotton that can be installed on the top and side, including a weather-resistant cover, upper insulation cotton, outlet flange, upper gasket, pressure relief element, lower gasket, and lower insulation cotton. The weather-resistant cover and the upper insulation cotton are bonded together with adhesive backing. The outlet flange is connected to the upper insulation cotton and the upper gasket with double-sided adhesive. The pressure relief element is fixed between the upper gasket and the lower gasket with adhesive backing. The lower insulation cotton is bonded to the lower surface of the pressure relief element with double-sided adhesive.

[0005] Through the above technical solution, the weather-resistant cover, upper insulation cotton, lower insulation cotton, outlet flange, upper gasket, lower gasket, and pressure relief element are quickly assembled by layering adhesive backing and double-sided adhesive. This simplifies the production process and reduces assembly costs. The upper insulation cotton covers the inside of the weather-resistant cover, and the lower insulation cotton adheres to the lower surface of the pressure relief element, forming a "double-layer insulation layer." This avoids the problem of insufficient insulation at the connection points, ensuring that when the device is installed in the energy storage cabinet, internal heat does not leak out and external heat does not intrude, maintaining a normal temperature and pressure environment. The upper and lower gaskets are tightly bonded to the pressure relief element through adhesive backing, forming a sandwich-type sealing structure. This not only prevents gas leakage but also provides waterproofing in outdoor environments, improving equipment reliability. The pressure relief element automatically ruptures or rotates open when overpressure occurs.

[0006] The present invention is further configured such that the weathering cover and the outlet flange are made of aluminum alloy plate, and the surface of the weathering cover is coated with an anti-corrosion layer.

[0007] Through the above technical solutions, the aluminum alloy plate is lightweight, which can reduce the overall load of the energy storage cabinet, and has high strength to withstand pressure. It is suitable for load-bearing requirements for top or side installation. The surface is coated with an anti-corrosion layer to resist corrosive environments such as salt spray and acids and alkalis, extend the service life of the explosion relief plate, and reduce the risk of explosion relief failure caused by material corrosion.

[0008] The present invention is further configured such that the side surface of the outlet flange is coated with an anti-corrosion layer.

[0009] With the above technical solution, the outlet flange, as the interface for bolting connection with the energy storage cabinet body, has its side surface directly exposed to the external environment. The anti-corrosion layer can prevent the bolt holes from rusting due to moisture and oxidation at the edge of the outlet flange, ensuring the installation is firm and avoiding the risk of the explosion relief plate falling off due to flange corrosion.

[0010] The present invention is further configured such that the upper and lower insulation cotton are aerogel boards.

[0011] The present invention is further configured to include a guide plate, which is fixedly connected to the weathering cover and the outlet flange by bolts.

[0012] Through the above technical solution, the guide plate, as a support structure for side installation, is connected to the weathering cover and outlet flange by bolts, providing a stable lateral fixing point for the explosion relief plate, avoiding the problem of easy shaking during side installation, and ensuring installation accuracy.

[0013] The beneficial effects of this utility model are as follows:

[0014] The upper and lower insulation cotton fully cover the equipment to form a double insulation design, avoiding heat conduction at the connection points and effectively maintaining a stable internal temperature to meet the requirements of normal temperature and pressure operation. It also has fireproof and noise reduction functions, supports top and side dual installation modes, and can be adapted to different spatial layouts with guide plates to expand the application scenarios. The weather-resistant cover and anti-corrosion coating design resists external environmental corrosion such as salt spray and humidity, extending the service life. The mechanical passive structure does not require electric drive, has no electronic component loss, has a long service life, requires no regular maintenance, and has extremely low maintenance costs.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] like Figures 1-3 As shown in the figure, this embodiment of an explosion relief plate with insulation cotton that can be installed on the top and side includes a weathering cover 1, upper insulation cotton 2, outlet flange 3, upper gasket 4, pressure relief element 5, lower gasket 6, and lower insulation cotton 7. The weathering cover 1 and outlet flange 3 are made of aluminum alloy plate. Aluminum alloy plate is lightweight, which improves explosion relief efficiency and reduces the overall load of the energy storage cabinet. It also has high strength and can withstand pressure, making it suitable for the load-bearing requirements of top or side installation. The surface of the weathering cover 1 is coated with an anti-corrosion layer, and the side surface of the outlet flange 3 is coated with an anti-corrosion layer. The surface anti-corrosion layer can resist corrosive environments such as salt spray and acid and alkali, extend the service life of the explosion relief plate, and reduce the risk of explosion relief failure due to material corrosion. The upper insulation cotton 2 and lower insulation cotton 7 are made of aerogel board and other insulation cotton materials. It also includes a guide plate 8, which is fixedly connected to the weathering cover 1 and outlet flange 3 by bolts.

[0021] The outlet flange 3 serves as the interface for bolting to the energy storage cabinet body. Its side surface is directly exposed to the external environment. The anti-corrosion layer can prevent the bolt holes of the outlet flange 3 from rusting due to moisture and oxidation, ensuring the installation is firm and avoiding the risk of the explosion relief plate falling off due to flange corrosion. The guide plate 8 serves as the support structure for side installation. It is connected to the weathering cover 1 and the outlet flange 3 by bolts, providing a stable lateral fixing point for the explosion relief plate, avoiding the problem of easy shaking during side installation, and ensuring installation accuracy. The upper insulation cotton 2 and the lower insulation cotton 7 fully cover to form a double insulation design, avoiding heat conduction at the connection point, effectively maintaining the internal temperature stability of the equipment, and meeting the requirements of normal temperature and pressure operating conditions.

[0022] When this device is installed on the side of the energy storage cabinet, under normal conditions, the pressure relief element 5 is tightly fixed by the upper gasket 4 and the lower gasket 6, maintaining the overall sealing of the explosion relief plate together with the outlet flange 3, etc. At this time, the weathering cover 1 is firmly connected to the guide plate 8, and the guide plate 8 is firmly fixed to the inner wall of the energy storage cabinet, making the explosion relief plate and the energy storage cabinet form a relatively closed whole. Once an explosion occurs inside the energy storage cabinet, the pressure will rise sharply and instantaneously. When the pressure value exceeds the preset opening pressure value of the pressure relief element 5, a huge pressure will act on the pressure relief element 5. Since the connection between the pressure relief element 5 and the upper gasket 4 and the lower gasket 6 is not absolutely rigid, under this powerful pressure impact, the pressure relief element 5... The pressure relief element 5 will rotate in a fan shape around the connection between the weathering cover 1 and the guide plate 8. The guide plate 8 plays a crucial role here. It not only provides a stable side mounting base for the explosion relief plate, but also restricts the opening direction and angle of the explosion relief plate during the rotation and opening process of the pressure relief element 5. According to the design, the opening angle of the explosion relief plate is controlled between 45° and 60°. This angle can ensure that the high-pressure gas and flame inside the energy storage cabinet are discharged quickly and effectively, avoiding the continuous accumulation of pressure and causing a more serious explosion. It can also guide the flame to spray upward, minimizing the damage to personnel and equipment around the energy storage cabinet, and providing strong protection for the safe operation of the energy storage cabinet. In addition, the pressure relief element 5 is driven by mechanical passive force without electric drive, and has no electronic component loss and a long service life.

[0023] The weatherproof cover 1 is bonded to the upper insulation cotton 2 with adhesive backing. The outlet flange 3 is connected to the upper insulation cotton 2 and the upper gasket 4 with double-sided adhesive. The pressure relief element 5 is fixed between the upper gasket 4 and the lower gasket 6 with adhesive backing. The lower insulation cotton 7 is bonded to the lower surface of the pressure relief element 5 with double-sided adhesive.

[0024] By using a combination of adhesive backing and double-sided adhesive, the weathering cover 1, upper insulation cotton 2, lower insulation cotton 7, outlet flange 3, upper gasket 4, lower gasket 6, and pressure relief element 5 can be quickly assembled, simplifying the production process and reducing assembly costs. The upper insulation cotton 2 covers the inside of the weathering cover 1, and the lower insulation cotton 7 adheres to the lower surface of the pressure relief element 5, forming a "double-layer insulation layer" to avoid the problem of insufficient insulation at the connection points. This ensures that when the device is installed in the energy storage cabinet, its internal heat does not leak out and external heat does not intrude, maintaining a normal temperature and pressure environment. The upper gasket 4 and lower gasket 6 are tightly bonded to the pressure relief element 5 with adhesive backing, forming a sandwich-type sealing structure. This not only prevents gas leakage but also provides waterproofing in outdoor environments, improving equipment reliability. The pressure relief element 5 can automatically rupture or rotate to open under overpressure without electronic control, avoiding explosion failure due to electronic component malfunction. It is suitable for environments without power supply or electromagnetic interference.

[0025] The working principle of this utility model is as follows: When the device is installed on the top of the energy storage cabinet, it is directly fixed to the top of the energy storage cabinet by bolts and outlet flange 3. When it needs to be installed on the side of the energy storage cabinet, a guide plate 8 is added to the pressure relief element 5. The weathering cover 1, upper insulation cotton 2, outlet flange 3, upper gasket 4, pressure relief element 5 and lower gasket 6 are connected by bolts to fix the pressure relief plate to the side of the energy storage cabinet. When the internal pressure of the energy storage cabinet is overpressurized, the pressure relief element 5 opens in a fan shape along the fixed side of the weathering cover 1 to quickly release the pressure. This structure is a mechanical passive opening, which does not require electronic equipment, has high stability and low maintenance cost. After rotation, it guides the flame upward to avoid injury to personnel and equipment.

[0026] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
