Description

Technical Field

[0001] The utility model relates to a fire fighting technology, in particular to a safety pressure relief structure of an energy storage container. Background Art

[0002] According to the provisions of GB50370, the gas fire extinguishing system protection area should be equipped with a pressure relief port. The door of the pressure relief port will automatically open when the pressure difference between indoor and outdoor is greater than 1100Pa±50Pa to release the indoor pressure. Chinese patent CN220869186U discloses a pressure relief port structure in the protection area, including a wall and two left-right symmetrical magnetic buffer components. A pressure relief window is opened on the wall, and a shutter is fixedly installed on the inner side of the pressure relief window. A sealing structure is provided on the outer side of the pressure relief window. The two magnetic buffer components are respectively arranged on both sides of the bottom of the sealing structure and are used for buffering when the sealing structure is sealed. Although the scheme is provided with a sealing structure, it was found during the IP55 protection level test that rainwater still overflowed and penetrated through the sealing ring, and if the infiltrated water cannot be discharged, it will enter the container and cannot meet the IPX5 waterproof level. Therefore, a rain cover for the pressure relief port must be added to the container body. The overall cost is higher and the appearance is affected. Utility Model Content

[0014] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the implementation modes and the accompanying drawings.

[0015] See also Figure 1 and 2 The pressure relief window 1 and the shutter 2 of the utility model are arranged oppositely at the pressure relief port of the energy storage container body 3, one outside and one inside. The window 11 of the pressure relief window 1 is hinged to the cover plate 12 by connecting the rotating shaft 124, and the periphery of the window 1 is provided with a groove to accommodate the inner folding edge 121 of the cover plate. Figure 3 As shown, EVA sponge tape 123 is arranged around the inner side of the cover plate 1, and oppositely, a frame 112 is arranged in the groove of the window body 11, and a connection surface is arranged on the upper edge of the frame to be in close contact with the EVA sponge tape 123. Three magnets 115 are arranged in the lower window groove 113 of the window body 11, and the magnets 115 are adsorbed on the inner folding edge 121 of the lower end cover of the metal cover plate.

[0016] like Figure 4 As shown, the inner folding edge 121 of the upper cover plate 12 can rotate in the upper window groove 111 of the window body 11. When the pressure relief window is closed, the inner folding edge 121 of the upper cover plate abuts against the wall of the upper window groove 111 to block dust. Figure 1 and Figure 4As shown, a guide plate 122 (connected by four columns) is provided on the inner side of the cover plate 12, and a guide groove is formed between the cover plate 12 and the guide plate 122. A window baffle 111a extending from the lower edge of the groove 111 at the upper end of the window body 11 is obliquely extended between the guide grooves of the cover plate 12 and the guide plate 122. Two overflow holes 114a are provided on the horizontal vertical surface 114 at the bottom of the vertical frame of the window body 11. The overflow holes 114a are staggered from the three magnets 115. The overflow hole 114a has four openings, and an exhalation diaphragm 116 is clamped in the middle. The lower exhalation diaphragm 116 covers the four openings of the overflow hole 114a to prevent dust.

[0017] like Figure 5 , 6 After entering the upper window groove 111 from the inner folded edge 122 of the cover plate at the upper end, the rainwater overflows from the EVA sponge tape 123 at the upper end and enters the lower part of the upper window groove 111. However, under the guidance of the window baffle 111a, it will not enter the pressure relief port but flow to the guide groove between the cover plate 12 and the guide plate 122, and flow from the lower end of the guide groove to the horizontal vertical surface 114 at the bottom of the window frame 11. The EVA sponge tape at the lower edge of the guide plate is arranged at the lower end of the guide plate 122 to be in close contact with the upper edge of the lower window groove 113 to prevent the rainwater from splashing upwards into the pressure relief port. When the rainwater accumulates to a certain amount, the exhalation diaphragm 116 cannot cover the four openings of the overflow hole 114a under the action of gravity, and the rainwater flows downward, then passes between the three magnets 115 and flows out from the lower edge of the lower window groove 113.

[0018] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
