Description

Technical Field

[0001] This utility model relates to the field of energy storage fire protection equipment technology, and in particular to an explosion relief device with lateral limiting for thermal runaway of an energy storage cabinet. Background Technology

[0002] Currently, in the field of energy storage fire protection, explosion relief panels are mostly installed on top of energy storage cabinets. However, with the development of the energy storage industry, the requirements for site space utilization are becoming increasingly stringent, and the stacking of energy storage cabinets is becoming a trend. The method of installing explosion relief panels on top restricts the stacking of energy storage cabinets and cannot meet the needs of efficient site utilization. If the explosion relief panels are installed on the side of the energy storage cabinet, a new problem arises: if there is no guide plate during side explosion relief, the pressure and debris generated by the explosion can cause serious injury to surrounding equipment and personnel. Existing technologies do not yet have a good solution to meet the requirements of side explosion relief and achieve guidance function. Utility Model Content

[0003] To address the aforementioned shortcomings in the existing technology, the purpose of this utility model is to provide a lateral explosion relief device with limiting function for thermal runaway of energy storage cabinets, thereby solving the problem of lateral installation of explosion relief devices in the energy storage fire protection industry, enabling energy storage cabinets to be stacked, improving site utilization, and allowing the device to open according to the designed opening method during explosion relief, playing a guiding role and avoiding damage to the surrounding area.

[0004] A thermal runaway lateral pressure relief device for an energy storage cabinet includes a base sealing gasket, a base flange, a sealing gasket, a housing, a pressure relief element, a cover plate, a rotating bracket, a rotating shaft, a bolt one, a reinforcing rib, a pop rivet, a traction component, a bolt two, and thermal insulation cotton. The base sealing gasket is connected to the base flange; the base flange locks the housing, sealing gasket, and base flange through a pressure relief element; the rotating shaft is combined with the rotating bracket and the hole on the base flange, and the rotating bracket is locked to the housing by bolts; The insulation cotton is placed inside the shell; the cover plate is fixed to the shell by a pull-out rivet; the second bolt connects the reinforcing rib plate to the shell, the traction component and the base flange; during explosion relief, the shell, cover plate and insulation cotton are rotated open together by the rotating bracket.

[0005] Preferably, the base sealing gasket is made of rubber, foamed silicone rubber, or foamed EPDM material, and its fireproof and waterproof ratings meet the design requirements.

[0006] Preferably, the base flange is a sheet metal part made of carbon steel or stainless steel.

[0007] Preferably, the insulation cotton is made of rubber insulation, rock wool insulation, glass fiber insulation or aerogel insulation material, which meets the requirements of thermal conductivity and fire resistance rating.

[0008] Preferably, the pressure relief element includes a pressure relief gasket and a pressure relief screw, which are limited by a traction member with a limiting angle of 40°-60°.

[0009] The beneficial effects of this utility model are as follows: This invention enables lateral explosion venting of the energy storage cabinet, solving the problem of traditional top-venting limiting the stacking of energy storage cabinets, effectively improving site utilization, and meeting the space requirements for large-scale application of energy storage equipment. By setting limit devices and guiding structures, the pressure can be redirected during explosion venting, causing the pressure to rise and thus playing a good guiding role. This prevents the pressure and debris generated during the explosion from causing damage to surrounding equipment and personnel, greatly improving the safety of the energy storage system. The pressure relief element is a combination of an explosion relief gasket and an explosion relief screw, which has the characteristics of low tensile force. It can stably control the opening pressure within the design range, ensuring that the explosion relief device opens accurately under appropriate pressure conditions and protecting the safety of the energy storage cabinet. Insulation material has been added to the structure, enabling the explosion venting device to have the same insulation effect as the installed energy storage cabinet, ensuring the stability of the internal environment of the energy storage cabinet and facilitating the normal operation of the energy storage equipment. The combination of the base flange and the base sealing gasket can effectively prevent rainwater from entering the interior in outdoor environments, providing excellent waterproof performance and airtightness that meets design requirements, thereby improving the environmental adaptability and service life of the explosion relief device.

The base sealing gasket 1 is combined with the base flange 2. The base sealing gasket 1 is made of soft sealing materials such as rubber, foamed silicone rubber or foamed EPDM, and its fireproof and waterproof ratings meet the design requirements. It plays a sealing role when installed with the energy storage cabinet. The base flange 2 is a sheet metal part, which is assembled by laser cutting, bending and welding. The material is carbon steel or stainless steel and other metal materials. The corresponding metal material can be selected according to customer requirements and different working conditions. The anti-corrosion requirements can also be improved by spraying.

[0018] The base flange 2 is combined with the sealing gasket 3, the housing 4, and the pressure relief element 5, and the housing 4, the sealing gasket 3, and the base flange 2 are locked together by the pressure relief element 5. The rotating shaft 8 is combined with the rotating bracket 7 and the holes on the base flange 2, and then the rotating bracket 7 and the housing 4 are locked together by bolts 9. The thermal insulation cotton 14 is made of materials that meet the requirements of thermal conductivity and fire resistance, such as rubber insulation, rock wool insulation, glass fiber insulation or aerogel insulation. The cover plate 6 is combined with the housing 4 and fixed by the pop rivet 11; bolt 2 13 connects the reinforcing rib plate 10 with the housing 4, the traction component 12 and the base flange 2 together. During the explosion venting, the shell 4, cover plate 6, and insulation cotton 14 are rotated and opened together by the rotating bracket 7. The pressure relief element 5 is the main component for opening, which is composed of explosion relief gasket and explosion relief screw. It is limited by the traction component 12, and the limiting angle can be adjusted between 40° and 60°.

[0019] In the actual installation process, firstly, the base sealing gasket 1 and the base flange 2 are assembled.

Next, the sealing gasket 3 and the housing 4 are installed on the base flange 2 in sequence, and they are locked and fixed by the pressure relief element 5. Assemble the rotating shaft 8 with the holes on the rotating bracket 7 and the base flange 2, and then use bolt 1 9 to lock the rotating bracket 7 to the housing 4.
