[0002] Hydrogen stations are flammable and explosive places, which means that when hydrogen is produced, used, or stored, combustion and explosion may occur under certain conditions, leading to accidents such as personal injury and property damage. Hydrogen stations are very prone to combustion and explosion accidents, so it is necessary to use explosion-proof doors that can effectively prevent the spread of explosion shock waves and flames. However, the current explosion-proof doors themselves are generally heavy. If an explosion inside the hydrogen station blows the explosion-proof door away, it is very likely to injure the staff, and in serious cases, it may even threaten the life safety of the staff. In addition, the door bolts of the explosion-proof doors are generally mechanical. In the event of an explosion or fire, it is very likely that the explosion-proof door will not be able to be closed or opened normally, resulting in personnel being stranded and unable to escape from the danger zone in the first time, resulting in loss of life safety. An explosion-proof door suitable for flammable and explosive places in hydrogen stations is needed to solve this problem. Utility Model Content

DETAILED DESCRIPTION

[0023] Below, the utility model is further described with reference to the accompanying drawings and specific embodiments:

The two special-shaped baffles 901 and the two groups of bolt rods 902 are all slidably connected to the inner wall of the explosion-proof door 2. The outer surfaces of the two groups of bolt rods 902 are all slidably connected to the slots inside the door frame body 1. The outer sides of the bolt rods 902 are sleeved with return springs 903. A floor-standing bolt rod 1502 is installed on the limit bolt mechanism 15. The outer surface of the floor-standing bolt rod 1502 is fixedly connected to the rotating groove rod 1501. The front of the explosion-proof door 2 is fixedly connected to the rear end of the positioning column 1504. The outer surface of the positioning column 1504 is fixedly connected to the magnet sleeve 1505. The outer surface of the magnet sleeve 1505 contacts the inner wall of the rotating groove rod 1501. The outer surface of the explosion-proof door 2 is fixedly connected to the slotted plate 1503.

[0026] In this embodiment, the main material of the explosion-proof door should have the characteristics of high strength, corrosion resistance, high temperature resistance, etc. Considering the special requirements of hydrogen places, we choose stainless steel as the main material, which has excellent mechanical properties, corrosion resistance and stamping resistance. Multiple groups of weight-reducing openings are opened inside the door frame to fill rock wool and other explosion-proof materials, which can absorb and disperse the explosion energy and further increase the explosion-proof performance of the door leaf. At the same time, special alloy materials are used in key parts to improve the overall strength and explosion-proof performance of the explosion-proof door.

[0027] Example 2

[0028] refer to Figures 4 to 6Example 2 is described. This embodiment further describes Example 1. It includes a quick-release mechanism 6 installed on the door frame body 1, a limit rod 602 installed on the quick-release mechanism 6, the inner wall of the external frame 3 and the quick-release baffle 4 is slidably connected to the outer surface of the limit rod 602, the front end of the limit rod 602 is fixedly connected to the limit pull plate 601, the outer sleeve of the limit rod 602 is provided with a limit spring 603, and a limit groove 806 is installed on the flashlight dual-purpose limit mechanism 8. The upper surface of the limit groove 806 is fixedly connected to the limit pull plate 601. A rubber stopper 807 is fixedly connected to the lower side surface, the outer surface of the limit groove 806 is fixedly connected to the inner wall of the explosion-proof door 2, the inner wall of the limit groove 806 is rotatably connected to a load-bearing rotating block 805, a remote-controlled electric push rod 801 is installed inside the load-bearing rotating block 805, the output end of the remote-controlled electric push rod 801 is fixedly connected to two push grooves 802, the inside of the two push grooves 802 is fixedly connected to two hand pull rods 803, and the outer surfaces of the two hand pull rods 803 are both covered with a heat insulation sleeve 804;

[0029] In this embodiment, by pulling the limit pull plate 601 forward, the limit rod 602 can be driven to release the limit on the quick-release baffle 4, so that the quick-release baffle 4 can fall into the inside of the bearing groove 7, and two hand pull rods 803 are used to pull the two push grooves 802, so that the two push grooves 802 can release the limit on the two special-shaped baffles 901, and the explosion-proof door 2 can be conveniently opened manually.

[0030] In specific applications, this device can drive the two push grooves 802 to move by starting the remote-controlled electric push rod 801, so that the two push grooves 802 can release the limit on the special-shaped baffle 901. Under the elastic force of the two sets of reset springs 903, the two special-shaped baffles 901 can be driven to move towards each other, so that the two sets of bolt rods 902 can release the limit on the door frame body 1, and finally the explosion-proof door 2 can be opened. When the hydrogen station is hit by an emergency and the remote-controlled electric push rod 801 cannot be controlled by the remote controller, by pulling the limit pull plate 601 forward, the limit rod 602 can be driven to release the limit on the quick-release baffle 4, so that the quick-release baffle 4 can fall into the inside of the bearing groove 7, and two hand pull rods 803 are used to pull the two push grooves 802. The two push grooves 802, the remote-controlled electric push rod 801 and the bearing turn block 805 rotate with the center of the connecting axis connecting the bearing turn block 805 and the limit groove 806 as the origin, so that the two push grooves 802 can release the limit on the two special-shaped baffles 901, and the explosion-proof door 2 can be opened manually conveniently. When the explosion-proof door 2 is blown away by the explosion, its internal mass is reduced due to the multiple weight-reducing grooves 12 that are opened, which can greatly reduce the risk of injuring staff. By rotating the rotating slot rod 1501 in the direction away from the magnet sleeve 1505, the limit of the rotating slot rod 1501 by the magnet sleeve 1505 can be released, and the floor-standing door bolt rod 1502 can be vertically inserted into the preset slot on the ground, thereby preventing the explosion-proof door 2 from swinging due to wind or external force after opening. The explosion-proof door 2 is designed with high-strength materials, weight-reducing slots and added rock wool, and other optimized structural designs, enhanced sealing performance and other measures to improve the explosion-proof, fire-proof and leakage-proof capabilities of the explosion-proof door 2. At the same time, an explosion-proof electromagnetic push rod push rod method is added, which can quickly open the door leaf in an emergency to ensure the safe and stable operation of the hydrogen site.
