[0028] See also Figure 1 - Figure 6 , the utility model provides a technical solution: a ventilation device for safety engineering, comprising a ventilation pipe 1, and an outer groove 101 opened on the front side of the ventilation pipe 1;

[0029] A sealing structure 2 is provided on the outside of the outer trough 101, and the sealing structure 2 includes a sealing plate 201 covering the outside of the outer trough 101, a circular shell 202 is fixedly connected to the middle part of the outer side of the sealing plate 201, a plurality of movable grooves 203 distributed circumferentially are provided on the surface of the circular shell 202, a polygonal groove 204 is provided in the middle part of the surface of the circular shell 202, a turntable 205 is rotatably connected to the inside of the circular shell 202, a spiral track 206 is fixedly connected to the surface of the turntable 205, a plurality of sliders 207 distributed circumferentially are slidably connected to the spiral track 206, a fixed rod 208 is slidably connected to the movable groove 203, and one end of the fixed rod 208 passes through the movable groove 203 and is fixedly connected to the slider 207, a plurality of sleeves 210 are provided on the edge of the outer trough 101, and the fixed rod 208 is plugged into the sleeve 210; wherein, a center column 211 is fixedly connected to the middle part of the turntable 205, and a lifting sleeve 214 is sleeved on the top of the center column 211. A first spring 213 is fixedly connected between the lowering sleeve 214 and the center column 211, and the top of the lifting sleeve 214 is fixedly connected to the polygonal button 215; the polygonal groove 204 can limit the rotation angle of the polygonal button 215 to prevent the turntable 205 from rotating due to vibration, thereby causing the position of the fixing rod 208 to shift. The length of the fixing rod 208 is divided into various lengths according to the distance between the round shell 202 and the insertion sleeve 210. The length of the fixing rod 208 on the left and right sides is longer than that on the upper and lower sides. The number of polygonal grooves 204 and the fixing rod 208 is not less than six. The inner surface of the sealing plate 201 is fixedly connected to a sealing plate with a self-sealing ring, and the sealing plate is engaged with the outer groove 101, thereby assisting the bottom surface of the sealing plate to be fixedly connected to the baffle 201 and the bottom surface of the sealing plate to be fixedly connected to the baffle. The bottom surface of the sealing plate is fixedly connected to the baffle 201 and the bottom surface of the sealing plate is fixedly connected to the baffle.

[0030] Three replacement components 3 are arranged inside the ventilation pipe 1.

[0031] A plurality of intermediate blocks 209 are fixedly connected to the outer side of the sealing plate 201 . The intermediate blocks 209 are evenly distributed around the circumference. The fixing rods 208 are slidably connected to the intermediate blocks 209 . The insert sleeve 210 is fixedly connected to the ventilation pipe 1 .

[0032] Four vertical slots 212 are formed on the outer side of the central column 211 , and the vertical slots 212 are slidably connected to the lifting sleeve 214 ; the vertical slots 212 enable the central column 211 and the lifting sleeve 214 to rotate synchronously.

When the polygonal button 215 is in the polygonal groove 204, it cannot rotate, thereby preventing vibration from affecting the angle of the polygonal button 215.

[0034] The replacement component 3 includes a top groove 304 opened at the top of the ventilation pipe 1, and the top groove 304 is slidably connected to the filter cover 301, and the top of the filter cover 301 is fixedly connected to a sealing gasket 305, which fits the inner wall of the top groove 304, and the top of the filter cover 301 is rotatably connected to the rotating cap 303, and the two sides of the rotating cap 303 are fixedly connected with bent strips 307 symmetrically on the center, and the bent strips 307 are plugged with arc-shaped positioning sleeves 308; the ends of the bent strips 307 are fixedly connected to magnet blocks, and the magnet blocks can stably attract when inserted into the arc-shaped positioning sleeves 308, thereby preventing the bent strips 307 from detaching from the arc-shaped positioning sleeves 308, and the sealing gasket 305 can achieve sealing to prevent air leakage. The interior of the filter cover 301 is filled with a variety of filter media.

[0035] The arc-shaped positioning sleeve 308 is fixedly connected to the top of the ventilation pipe 1 , and the inner bottom surface of the ventilation pipe 1 is fixedly connected with a blocking bar 302 ; the blocking bar 302 is fitted with the bottom of the filter cover 301 .

[0036] A hand-held ring 306 is fixedly connected to the top of the rotating cap 303 .

[0037] Working principle: Before using this ventilation device for safety engineering, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 6 As shown, first, the polygonal button 215 is pressed with a tool to squeeze the lifting sleeve 214 and lower it along the vertical slot 212. Then, the polygonal button 215 is rotated to rotate the turntable 205, thereby allowing the spiral track 206 to drive the slider 207. As a result, the insertion rod 208 is pulled out of the insertion sleeve 210 under the movement of the slider 207, thereby allowing the sealing plate 201 to be quickly disassembled. In addition, the multiple insertion sleeves 210 ensure the stability of the sealing plate 201 after installation.

[0038] When only the filter cover 301 needs to be cleaned, the ring 306 is held and the rotating cap 303 is rotated to remove the bent insert 307 from the arc-shaped positioning sleeve 308 , thereby allowing the filter cover 301 to be directly removed from the top groove 304 .
