Description

Technical Field

[0001] This utility model relates to the field of new energy safety pressure relief technology, specifically a bottom-insulated explosion relief plate for energy storage cabinets. Background Technology

[0002] In recent years, with the rapid development of my country's new energy industry, energy storage technology has become a key link supporting the large-scale development and high-proportion grid connection of new energy sources. New energy power generation is characterized by intermittency, volatility, and randomness; energy storage systems can effectively balance power supply and demand, improving the stability and reliability of the power grid. However, during operation, the heat and gas generated by battery charging and discharging can cause a sharp increase in internal pressure in energy storage cabinets, posing safety hazards. Therefore, safe pressure relief technology for energy storage cabinets is particularly important.

[0003] Currently, explosion venting devices commonly used in the energy storage industry typically place the insulation layer above the explosion venting plate. However, this design has certain limitations during transportation. Due to the large size and heavy weight of energy storage cabinets, they usually need to be stacked in rows for transport. If the explosion venting device protrudes significantly above the cabinet, stacking becomes impossible, affecting transportation efficiency. Therefore, there is an urgent need for a bottom-insulated explosion venting device that can meet both pressure relief requirements and adapt to transportation and installation requirements. Utility Model Content

[0004] The purpose of this utility model is to provide a bottom-insulated explosion relief plate for energy storage cabinets, so as to solve the problem mentioned in the background art that the existing explosion relief devices commonly used in the energy storage industry have the insulation layer placed on top of the explosion relief plate, which makes it impossible to stack them and affects transportation efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bottom-insulated explosion relief plate for an energy storage cabinet, comprising an explosion relief plate, a pressure relief side flange at the top of the explosion relief plate, an explosion relief plate insulation part at the bottom, and a pressure-resistant side flange below the explosion relief plate insulation part. The explosion relief plate, the pressure relief side flange, the explosion relief plate insulation part, and the pressure-resistant side flange are connected as a whole by multiple bolts. The explosion relief plate includes a rectangular explosion relief piece with multiple explosion relief piece through holes evenly arranged on its four sides. The pressure relief side flange is a rectangular flange with multiple pressure relief flange holes near each side. The explosion relief plate insulation part includes a protective cover with insulation cotton inside. The pressure-resistant side flange is a rectangular equipment flange and is fixedly connected to the explosion relief port of the equipment. Multiple pressure-resistant flange holes are evenly arranged on each side of the pressure-resistant side flange.

[0006] Preferably, the protective cover includes a rectangular protective cover base plate, and vertically upward protective cover side plates are provided on all four sides of the protective cover base plate. A protective cover flange extending horizontally outward is provided on the top edge of a long protective cover side plate, and a plurality of protective cover through holes corresponding one-to-one with a plurality of explosion relief disc through holes are provided on the protective cover flange.

[0007] Preferably, the top ends of the three protective cover folds (excluding the one with protective cover folds) are all bonded and fixed to the bottom surface of the explosion relief plate.

[0008] Preferably, the inner sides of the bottom plate of the protective cover and the four side plates of the protective cover are provided with heat insulation cotton and are respectively bonded and fixed thereto.

[0009] Preferably, the outer side length of the pressure relief flange is equal to the outer side length of the explosion relief plate.

[0010] Preferably, multiple explosion relief disc through holes, multiple pressure relief flange holes, multiple protective cover through holes, and multiple pressure-resistant flange holes are respectively set one-to-one and connected into one unit using bolts.

[0011] Preferably, the explosion relief plate is a flat, slotted rupture disc.

[0012] Preferably, the insulation material is rock wool, and its density is ≥ kg / m³. 3 .

[0013] Preferably, rectangular gaskets are provided between the explosion relief plate and the pressure relief side flange, and between the explosion relief plate and the insulation part of the explosion relief plate and the pressure-resistant side flange.

[0014] Preferably, the gasket is of "automotive grade" to achieve the best sealing effect.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model uses a flat slotted rupture disc as the main pressure relief element. Through single-layer metal rupture disc technology and fixed-length connecting bridge design, the opening pressure of the rupture disc is more precise, the response speed is faster, and the manufacturing cost is lower.

[0017] 2. This utility model places the insulation cotton inside the energy storage cabinet, saving external space of the cabinet and ensuring that the explosion relief device does not protrude too much from the cabinet, making it easier to stack and transport in rows, thus improving transportation efficiency.

[0018] 3. The insulation material is rock wool with a density ≥120kg / m³. 3 It not only has good heat insulation effect, but can also effectively withstand the weight of outdoor snow, thus improving the durability and reliability of the device.

[0019] 4. An automotive-grade gasket was installed between the explosion relief plate and the flange to ensure the sealing performance of the device, prevent gas leakage, and further improve safety.

[0020] 5. This utility model is applicable to various energy storage cabinet scenarios, especially in the application of centralized large-scale development of new energy and local consumption of distributed new energy, and can effectively solve the problem of safe pressure relief of energy storage cabinets.

[0021] In summary, this utility model provides a bottom-insulated explosion relief plate with a reasonable structure and superior performance, which can meet the multiple needs of energy storage cabinets in terms of pressure relief, heat preservation, transportation and installation, and has broad application prospects and promotion value.
