Description

Technical Field

[0001] The present application relates to the technical field of civil air defense engineering, and in particular to a sealing mechanism between a preset hole in a wall of a civil air defense engineering and a pipeline. Background Art

[0002] Civil air defense projects refer to underground protective buildings built separately to ensure the shelter of personnel and materials, civil air defense command, and medical rescue in wartime, as well as basements built in combination with ground buildings that can be used for air defense in wartime. Civil air defense projects are important facilities for preventing sudden attacks by the enemy, effectively sheltering personnel and materials, and preserving war potential. When laying pipelines in civil air defense projects, it is necessary to pass through protective closed walls and set up protective closed measures at the perforated locations.

[0003] In the patent document with the announcement number CN211716026U that has been announced, a civil air defense project pipe penetration structure is provided, which belongs to the field of civil air defense project pipeline technology, including a civil air defense wall, the outer wall of the civil air defense wall is provided with a reserved hole, the interior of the reserved hole is provided with a silencer cover, the interior of the silencer cover is provided with a pipe, the outer wall of the pipe is fitted with a sealing ring, the outer wall of the sealing ring is fitted with a silencer cover, four shock-absorbing pads are fixedly connected to the four corners of the silencer cover with support columns, the outer wall of the silencer cover is covered with a sound-absorbing layer, and the four shock-absorbing pads are all located inside the sound-absorbing layer. By arranging the shock-absorbing pads, the vibration generated by the vibration of the pipeline is transmitted to the shock-absorbing pads. The shock-absorbing pads are made of rubber material, which greatly buffers and absorbs the vibration, and has the effect of slowing down the vibration noise, thereby reducing the interference of the pipeline sound transmission to the civil air defense area, and solving the problem that in the existing civil air defense projects, the pipeline penetration through the wall is generally directly penetrated, and the pipeline vibration transmits energy to the wall, generating vibration noise, affecting the environment of the civil air defense area.

[0004] When the power pipeline is smaller than the preset hole, the reserved hole and the pipeline are sealed. When the above pipe-through structure is in use, it is sealed by installing a sealing ring on the outer wall of the installed pipeline and filling sealant between the pipeline and the reserved hole. However, in actual use, the sealant is usually injected into the reserved hole and the pipeline in liquid form, and because the reserved hole is usually made manually, the error is large, and the diameter may be different from the pipeline. The sealing plug has low flexibility for gaps of different sizes between the reserved hole and the pipeline, resulting in the problem of unformed liquid sealant easily flowing out during the sealing step. For this reason, the present application provides a sealing mechanism between the preset hole and the pipeline of the civil air defense project wall. Utility Model Content

According to the gap between the pipe and the reserved hole at this time, the third trapezoidal tube is pushed and adjusted toward the first trapezoidal tube to select the appropriate outer diameter of the first trapezoidal tube, the second trapezoidal tube, and the third trapezoidal tube for plugging. Then the delivery pipe is connected to the glue gun for sealing material, and the sealing material is sent into the gap between the pipe and the reserved hole through the delivery pipe for sealing. After the sealing material is solidified, the device is taken out. This device selects the appropriate outer diameter of the first trapezoidal tube, the second trapezoidal tube, and the third trapezoidal tube to plug the pipe and the reserved hole, which increases the flexibility of sealing and plugging gaps of different sizes between the reserved hole and the pipe, and greatly reduces the outflow of unformed liquid sealant during the sealing step.

[0008] As a preferred technical solution of the present application, the clamping mechanism includes a top plate, one side of the top plate is fixedly mounted on one end of the first trapezoidal tube, the bottom end of the top plate is fixedly connected to a first clamping plate, an adjusting rod is rotatably mounted on one side of the first clamping plate, and a second clamping plate is mounted on the outer surface of the adjusting rod.

[0009] By adopting the above technical solution, one end of the delivery pipe is clamped between the first clamping plate and the second clamping plate to limit the position of the one end of the delivery pipe, which is conducive to the smooth outflow of the sealant through the delivery pipe.

[0010] As a preferred technical solution of the present application, the maximum diameter of the first trapezoidal tube is greater than the minimum diameter of the second trapezoidal tube, and the maximum diameter of the second trapezoidal tube is greater than the minimum diameter of the third trapezoidal tube.

[0011] By adopting the above technical solution, since the maximum diameter of the first trapezoidal tube is greater than the minimum diameter of the second trapezoidal tube, when pushing and pulling the first trapezoidal tube, when the minimum diameter of the second trapezoidal tube is stuck at the maximum diameter of the first trapezoidal tube, the first trapezoidal tube and the second trapezoidal tube will not be separated, thereby improving the practicality during use.

[0012] As a preferred technical solution of the present application, anti-slip pads are fixedly installed on the opposite surfaces of the first clamping plate and the second clamping plate.

[0014] As a preferred technical solution of the present application, a handle is fixedly installed on one end of the third trapezoidal tube away from the second trapezoidal tube.

According to the gap between the pipe and the reserved hole at this time, push and adjust from the third trapezoidal pipe toward the first trapezoidal pipe to select the first trapezoidal pipe, the second trapezoidal pipe, and the third trapezoidal pipe with a suitable outer diameter for plugging. Then connect the delivery pipe to the glue gun for sealing material, and send the sealing material into the gap between the pipe and the reserved hole through the delivery pipe for sealing. After the sealing material is solidified, take out the device. This device selects the first trapezoidal pipe, the second trapezoidal pipe, and the third trapezoidal pipe with a suitable outer diameter to plug the pipe and the reserved hole, which increases the flexibility of sealing and plugging gaps of different sizes between the reserved hole and the pipe, and greatly reduces the outflow of unformed liquid sealant during the sealing step.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] Reference Figure 1-3 A sealing mechanism between a preset hole in a wall of a civil air defense project and a pipeline comprises a civil air defense wall 1, a preset hole 2 is opened inside the civil air defense wall 1, a pipeline 3 is passed through the reserved hole 2 inside the civil air defense wall 1, and telescopic sealing mechanisms 4 are arranged at both ends of the pipeline 3. The telescopic sealing mechanism 4 comprises a first trapezoidal tube 401, an opening is opened at the top end of the first trapezoidal tube 401, and the open end of the first trapezoidal tube 401 is sleeved on one end of the pipeline 3.

[0027] Among them, the second trapezoidal tube 402 is slidably connected to the outer surface of the first trapezoidal tube 401, and the third trapezoidal tube 403 is slidably connected to the outer surface of the second trapezoidal tube 402. The inner wall of the first trapezoidal tube 401 is provided with a first through hole 404, the inner wall of the second trapezoidal tube 402 is provided with a second through hole 405, and the inner wall of the third trapezoidal tube 403 is provided with a third through hole 406. The first through hole 404, the second through hole 405, and the third through hole 406 are connected, and a conveying pipe 6 is passed between the first through hole 404, the second through hole 405, and the third through hole 406. Two sets of clamping mechanisms 7 are arranged at one end of the first trapezoidal tube 401.

[0028] At the same time, the maximum diameter of the first trapezoidal tube 401 is greater than the minimum diameter of the second trapezoidal tube 402 , and the maximum diameter of the second trapezoidal tube 402 is greater than the minimum diameter of the third trapezoidal tube 403 ; a handle 9 is fixedly installed at one end of the third trapezoidal tube 403 away from the second trapezoidal tube 402 .

[0029] By fixing the delivery pipe 6 by the clamping mechanism 7, the pipe 3 is stuck inside the first trapezoidal tube 401. According to the gap between the pipe 3 and the reserved hole 2 at this time, the third trapezoidal tube 403 is pushed and adjusted in the direction toward the first trapezoidal tube 401 to select the first trapezoidal tube 401, the second trapezoidal tube 402, and the third trapezoidal tube 403 with a suitable outer diameter for plugging. Then the delivery pipe 6 is connected to the glue gun for applying the sealing material, and the sealing material is sent into the gap between the pipe 3 and the reserved hole 2 through the delivery pipe 6 for sealing. After the sealing material is solidified, the device is taken out. This device plugs the pipe 3 and the reserved hole 2 by pushing and adjusting the first trapezoidal tube 401, the second trapezoidal tube 402, and the third trapezoidal tube 403 with a suitable outer diameter, which increases the flexibility of sealing and plugging gaps of different sizes between the reserved hole 2 and the pipe 3, and greatly reduces the outflow of unformed liquid sealant during the sealing step.

[0030] In addition, since the maximum diameter of the first trapezoidal tube 401 is greater than the minimum diameter of the second trapezoidal tube 402, when the first trapezoidal tube 401 is pushed and pulled, when the minimum diameter of the second trapezoidal tube 402 is stuck at the maximum diameter of the first trapezoidal tube 401, the first trapezoidal tube 401 and the second trapezoidal tube 402 will not be separated, thereby improving the practicality during use. The handle 9 facilitates the user to push and adjust the direction from the third trapezoidal tube 403 toward the first trapezoidal tube 401 to select the appropriate outer diameter of the first trapezoidal tube 401, the second trapezoidal tube 402, and the third trapezoidal tube 403 for plugging, and push and pull the third trapezoidal tube 403, while linking the second trapezoidal tube 402, thereby improving the convenience during use.

[0031] Reference Figure 1-3The clamping mechanism 7 includes a top plate 701, one side of which is fixedly mounted on one end of the first trapezoidal tube 401, a first clamping plate 702 is fixedly connected to the bottom end of the top plate 701, an adjusting rod 703 is rotatably mounted on one side of the first clamping plate 702, and a second clamping plate 705 is mounted on the outer surface of the adjusting rod 703. The adjusting rod 703 is a screw rod, one end of which is fixedly mounted with a rotating block 704, a top end of the second clamping plate 705 is fixedly mounted with a guide rod 706, a slide rail is provided at the bottom of the top plate 701, and the guide rod 706 is slidably connected to the bottom of the top plate 701 through the slide rail.

[0032] When in use, one end of the delivery tube 6 is clamped between the first clamping plate 702 and the second clamping plate 705 to limit the position of the delivery tube 6, which is conducive to the smooth outflow of the sealant through the delivery tube 6. The anti-skid pad 8 increases the friction force when clamping the delivery tube 6, which improves the stability of the glue discharge at the delivery tube 6. The adjusting rod 703 is rotated by rotating the rotating block 704, and the position of the second clamping plate 705 is adjusted under the action of the thread. The guide rod 706 guides the second clamping plate 705 when it moves, thereby improving the tightness of the delivery tube 6 when clamped.

[0033] Reference Figure 2 The first clamping plate 702 and the second clamping plate 705 are fixedly mounted with anti-skid pads 8 on their opposite surfaces. The anti-skid pads 8 increase the friction force when clamping the delivery pipe 6, thereby improving the stability of the delivery pipe 6 when discharging glue.

[0034] Working principle: by fixing the delivery pipe 6 by the clamping mechanism 7, the pipe 3 is stuck inside the first trapezoidal pipe 401, and according to the gap between the pipe 3 and the reserved hole 2 at this time, the third trapezoidal pipe 403 is pushed and adjusted toward the first trapezoidal pipe 401 to select the first trapezoidal pipe 401, the second trapezoidal pipe 402, and the third trapezoidal pipe 403 with a suitable outer diameter for plugging, and then the delivery pipe 6 is connected to the glue gun for applying the sealing material, and the sealing material is sent into the gap between the pipe 3 and the reserved hole 2 through the delivery pipe 6 for sealing, and the device is taken out after the sealing material is solidified. This device selects the first trapezoidal pipe 401, the second trapezoidal pipe 402, and the third trapezoidal pipe 403 with a suitable outer diameter for plugging the pipe 3 and the reserved hole 2 by pushing and adjusting, thereby increasing the flexibility of sealing and plugging gaps of different sizes between the reserved hole 2 and the pipe 3, and greatly reducing the outflow of unformed liquid sealant during the sealing step;

[0035] In addition, since the maximum diameter of the first trapezoidal tube 401 is greater than the minimum diameter of the second trapezoidal tube 402, when pushing and pulling the first trapezoidal tube 401, when the minimum diameter of the second trapezoidal tube 402 is stuck at the maximum diameter of the first trapezoidal tube 401, the first trapezoidal tube 401 and the second trapezoidal tube 402 will not be separated, thereby improving practicality during use; by rotating the rotating block 704 to rotate the adjusting rod 703, the position of the second clamping plate 705 is adjusted under the action of the thread, and the guide rod 706 plays a guiding role when the second clamping plate 705 moves, thereby improving the tightness of clamping the delivery tube 6.

[0036] Among them, by clamping one end of the delivery tube 6 between the first clamping plate 702 and the second clamping plate 705, one end of the delivery tube 6 is limited, which is conducive to the smooth outflow of the sealant through the delivery tube 6. The adjusting rod 703 is rotated by rotating the rotating block 704, and the position of the second clamping plate 705 is adjusted under the action of the thread. The guide rod 706 guides the second clamping plate 705 when it moves, thereby improving the tightness of the delivery tube 6 when it is clamped.

[0037] At the same time, the anti-skid pad 8 increases the friction force when clamping the delivery pipe 6, thereby improving the stability of the delivery pipe 6 when discharging glue.
