[0040] Reference Figure 3 and Figure 4 The inner circle of the frame 100 is provided with a sealing layer 101, which is made of rubber. The first door leaf 200 and the second door leaf 300 are both in contact with the sealing layer 101. The first door leaf 200 is provided with a first receiving groove 201 at one end away from the first door leaf 200 that is rotatably connected to the frame 100. The length direction of the first receiving groove 201 is arranged in the vertical direction and the opening faces the second door leaf 300. A plurality of bolts 203 are arranged in the first door leaf 200. In this embodiment, there are three bolts 203, which are cylindrical and arranged horizontally. Each bolt 203 is evenly spaced in the vertical direction. One end of each bolt 203 passes through the inner wall of the first receiving groove 201 and is located in the first receiving groove 201 and faces the second door leaf 300. A rack 205 is arranged in the first door leaf 200. The rack 205 is arranged horizontally. Each bolt 203 is connected to one end of the rack 205. The rack 205 is meshed with a rotating gear 204.

[0041] A plurality of first elastic bags 202 are arranged in the first receiving groove 201. The outer wall of the first elastic bag 202 close to the inner wall of the first receiving groove 201 is connected to the inner wall of the first receiving groove 201. In the present embodiment, there are four first elastic bags 202 made of rubber. The four first elastic bags 202 and the three bolts 203 are alternately distributed in the vertical direction.

[0042] The second door leaf 300 is provided with a second receiving groove 301 at one end away from the second door leaf 300 that is rotatably connected to the frame 100. The length direction of the second receiving groove 301 is arranged in the vertical direction and the opening faces the first door leaf 200. A plurality of connecting pipes 303 are arranged in the second receiving groove 301. The connecting pipes 303 are round pipes and are arranged horizontally. In this embodiment, there are three connecting pipes 303. The central axes of the three connecting pipes 303 are respectively colinear with the central axes of the three bolts 203. One end of the connecting pipe 303 opens toward the second receiving groove 301. The other end of the connecting pipe 303 passes through the inner wall of the second receiving groove 301 and enters the second door leaf 300 and is fixed to the second door leaf 300. Each connecting pipe 303 is connected to a pressure detection member 304, and the pressure detection member 304 adopts a pressure sensor.

[0043] The first door leaf 200 and the second door leaf 300 are both provided with a water supply assembly 400 and a water source. The water source is located at the bottom of the first door leaf 200 and the second door leaf 300 and is a water collecting tank. The water supply assembly 400 includes a water pump 401 and a water pipe 402. The water pump 401 is connected to the water source. There are multiple water pipes 402 in the first door leaf 200, and the ends of the water pipes 402 are respectively connected to the first elastic capsules 202 after being inserted into the first receiving groove 201. The other end of each water pipe 402 in the first door leaf 200 is connected to the water pump 401. There are multiple water pipes 402 in the second door leaf 300, and the ends of the water pipes 402 are respectively connected to the second elastic capsules 302 after being inserted into the second receiving groove 301.

[0044] The water pump 401 is electrically connected to a controller, which adopts an S7-200 PLC. The pressure detection component 304 is electrically connected to the controller. The pressure detection component 304 is used to detect the pressure of the door bolt 203 on it and output the pressure value. The controller is used to receive the pressure value and compare it with a preset value. When the pressure value is less than the preset value, the controller controls the water pump 401 to pump water to each water pipe 402; when the pressure value is greater than the preset value, the controller controls the water pump 401 to supply water to each water pipe 402.

[0045] Reference Figure 2 , Figure 3 and Figure 4A rotating shaft 206 is provided on one side of the first door leaf 200, one end of the rotating shaft 206 is connected to the center of the rotating gear 204, and the other end of the rotating shaft 206 is located outside the first door leaf 200 and is connected to the rotating wheel 207 and locked by the locking assembly 500. The locking assembly 500 includes a first connecting rope 501 and a second connecting rope 502, both of which are steel wire ropes. In other embodiments, both of the first connecting rope 501 and the second connecting rope 502 are iron chains. One end of the first connecting rope 501 is connected to one side of the first door leaf 200, and the other end of the first connecting rope 501 is wound around the rotating wheel 207. One end of the second connecting rope 502 is connected to the middle of one side of the second door leaf 300, and the other end of the second connecting rope 502 is wound around the rotating wheel 207 and the first connecting rope 501.

[0046] The implementation principle of a highly sealed double-leaf explosion-proof door in the embodiment of the present application is as follows: after the first door leaf 200 and the second door leaf 300 are rotated to close, the rotating wheel 207 is rotated. When the rotating wheel 207 rotates, it drives the rotating gear 204 to rotate through the rotating shaft 206, so as to drive the rack 205 to drive one end of the bolt 203 to move and insert into the connecting pipe 303 until one end of the bolt 203 abuts against the pressure detection component 304, and the water pump 401 fills water into the first elastic bag 202 and the second elastic bag 302 through the water pipe 402. After the first elastic bag 202 and the second elastic bag 302 are filled with water and expanded, they abut against each other, thereby improving the sealing between the first door leaf 200 and the second door leaf 300. Sealing, one end of the first connecting rope 501 and the second connecting rope 502 are both wound around the rotating wheel 207; when it is necessary to open the first door leaf 200 and the second door leaf 300, the first connecting rope 501 and the second connecting rope 502 are removed from the rotating wheel 207, and the rotating wheel 207 is rotated in the opposite direction, one end of the bolt 203 is away from the pressure detecting component 304, and the water pump 401 pumps water to the first elastic bag 202 and the second elastic bag 302 through the water pipe 402, and the first elastic bag 202 and the second elastic bag 302 become deflated, and the rotating wheel 207 is continued to be reversed to make the bolt 203 move out of the connecting pipe 303, so that the first door leaf 200 and the second door leaf 300 can be rotated to open.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
