Detailed Description
The invention is described in further detail below with reference to specific embodiments.
As shown in fig. 1, a through hole is formed in the civil air defense wall 1, the civil air defense straight pipes 2 with the same diameter of each cross section are arranged in the through hole so as to penetrate through the civil air defense wall 1, and two ends of each civil air defense straight pipe 2 penetrate out of the civil air defense wall 1. The sealing device for the civil air defense straight pipe 2 comprises the civil air defense straight pipe 2, and further comprises a first sealing cover 3, a second sealing cover 11, a first straight screw rod 4 and a second straight screw rod 12, wherein the first sealing cover 3 is taken as an example and is a round cover with the radius larger than that of the civil air defense straight pipe 2, as shown in fig. 2, a first rod installing hole 8 and a second rod installing hole 7 which axially penetrate through the first sealing cover 3 are formed, sealing rings are arranged in the two rod installing holes, a first far point 10 is arranged on the first rod installing hole 8 and is the farthest away from the second rod installing hole 7, a second far point 9 is arranged on the second rod installing hole 7 and is the farthest away from the first rod installing hole 8, the distance between the first far point 10 and the second far point 9 is equal to the inner diameter of the civil air defense straight pipe 2, and the pipe orifice projection 6 of the civil air defense straight pipe 2 on the sealing cover is tangent to the first rod installing hole 8, the second rod installing hole 7. The second sealing cover 11 is symmetrical to the first sealing cover 3. The first straight screw rod 4 and the second straight screw rod 12 are symmetrical to each other, and the respective diameter is less than or equal to one fifth of the diameter of the civil air defense straight pipe 2 and is more than or equal to one tenth of the diameter of the civil air defense straight pipe 2.
When the sealing device of the civil air defense straight pipe 2 is installed, a worker sleeves the first sealing cover 3 to the left end of the first straight screw rod 4 and the left end of the second straight screw rod 12 from left to right through the first rod installing hole 8 and the second rod installing hole 7 of the first sealing cover 3. Then, two mouths of pipe of people's air defense straight tube 2 department sets up the cushion, makes two first, second straight lead screw 4, 12 from a left side turn right and pass the cushion of the mouth of pipe in the left side of people's air defense straight tube 2 and stretch into respectively and place in the people's air defense straight tube 2, all wear out the cushion of the right mouth of pipe and the mouth of pipe in the right side of people's air defense straight tube 2 at the left and right both ends of two first, second straight lead screw 4, 12. And then the second sealing cover 11 is sleeved on the right ends of the first and second straight screw rods 4 and 12 through the first and second rod installing holes 8 and 7 of the second sealing cover 11. Next, four nuts 5 are screwed to the left and right ends of the first and second straight screw rods 4 and 12, respectively, and the nuts 5 are screwed so that the two nuts 5 located on the same straight screw rod are axially close to each other, so that the nuts 5 serve as locking members to axially clamp the distal ends of the first and second sealing covers 3 and 11, so that the proximal ends of the first and second sealing covers 3 and 11 respectively cover the left and right pipe orifices of the civil air defense straight pipe 2 and clamp the corresponding cushion.
