Description

Technical Field

[0001] The utility model relates to the technical field of civil air defense engineering, and more specifically, to a ventilation pipe design structure taking civil air defense into consideration. Background Art

[0002] In modern urban construction, the development and utilization of underground space is increasing, especially for civil air defense projects, whose design and construction requirements are becoming more and more stringent. At the same time, it is also necessary to consider the requirements of human comfort and living environment such as ventilation and exhaust.

[0003] However, existing civil air defense projects, when used as civil air defense fortifications, need to achieve ventilation effects, so multiple pipes need to be set up for ventilation operations. However, in some civil air defense projects, due to direction problems, there will be multiple ventilation ducts intersecting or ventilation ducts intersecting with other ducts. When the civil air defense fortifications are put into use, these locations are prone to collisions between the pipes due to vibrations, thereby affecting the use of each pipe.

[0004] After searching, it was found that a Chinese patent with publication number CN219797466U discloses a ventilation pipe design structure that takes civil air defense into consideration. By providing a first pipe fixing member and a second pipe fixing member for fixing two adjacent pipes and an adjustable support device for isolating adjacent pipes, isolation support between adjacent pipes is achieved, thereby avoiding the problem of collision between adjacent pipes due to vibration when the civil air defense project is put into use.

[0005] However, when this structure is actually used, according to the attached drawings of the above structure, the first pipe fixing member and the second pipe fixing member used for installing the pipe can only be used for installing circular ventilation ducts. However, in actual civil air defense engineering applications, there will also be a certain number of square ventilation ducts, and this structure is very inconvenient for the installation of square ventilation ducts and has a relatively low scope of application. In view of this, the utility model proposes a ventilation duct design structure that takes civil air defense into consideration. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the utility model provides a ventilation pipe design structure taking into account both civil air defense and the like, so as to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a ventilation pipe design structure that takes into account civil air defense, comprising a damping sleeve, a damping sleeve rod and two pipe support structures, one end of the damping sleeve rod is arranged inside the damping sleeve, and the two pipe support structures are symmetrically installed on one end of the damping sleeve rod and the damping sleeve respectively.

[0008] It can be seen that in the above structure, the two pipe support structures can clamp and support the two pipes, and the damping sleeve and the damping sleeve rod can isolate the two clamped and supported pipes, thereby avoiding the collision between two adjacent pipes.

[0009] In order to be able to clamp square ventilation pipes and round ventilation pipes and improve the scope of use, preferably, the pipe support structure includes a concave frame, which is installed at one end of the damping sleeve and the damping sleeve, and the two inner walls of the concave frame are provided with installation grooves, and a two-way screw rod is arranged inside the installation groove, and two movable seats are arranged outside the two-way screw rod, and an adjustment block is arranged at one end of the two-way screw rod, and one end of the two-way screw rod is connected to the adjustment block, and the two movable seats are both connected to the external thread of the two-way screw rod, and the clamping plates at one end of the two movable seats are symmetrical and inclined outwardly, and the clamping plates are inclined at one end of the movable seat, and the surface of the clamping plate is provided with a rubber anti-slip pad, and the surface of the rubber anti-slip pad is provided with a card groove, and the rubber anti-slip pad is adhered to the surface of the clamping plate, and the card groove opened on the surface of the rubber protective pad is opened vertically.

[0010] In order to be able to absorb energy from the vibration of two adjacent pipes, preferably, the outer diameter of the damping sleeve is smaller than the inner diameter of the damping sleeve, and one end of the damping sleeve is slidably connected inside the damping sleeve, a damping movable block is provided inside the damping sleeve at one end of the damping sleeve rod, an energy absorbing spring is provided at the bottom of the damping movable block, the outer wall of the damping movable block is slidably connected to the inner wall of the damping sleeve, the bottom end of the energy absorbing spring is fixedly mounted on the bottom of the inner cavity of the damping sleeve, and the top end of the energy absorbing spring is fixedly mounted on the bottom of the damping movable block.

[0011] Technical effects and advantages of the utility model:

[0012] 1. By setting up the pipe support structure, the two-way screw rod drives the two moving seats to move closer and farther from each other, so as to adjust the distance between the two adjacent clamping plates according to the size of the circular pipe and the square pipe, so as to facilitate the installation of pipes of different sizes. The two clamping plates clamp the outer surface of the circular pipe, and the rubber anti-skid pad is used to provide a protective and anti-skid effect, so as to achieve the clamping and support of the circular pipe. At the same time, the four corners of the square pipe are aligned with the vertical slots opened by the corresponding rubber anti-skid pads, and the square pipe is clamped by the clamping plates, so as to achieve the clamping and support of the square pipe, and then achieve the phenomenon of clamping the square pipe and the circular pipe, thereby improving the scope of use;

[0013] 2. The damping sleeve rod with a specific damping effect slides inside the damping sleeve, which can weaken part of the vibration from between the two pipes. At the same time, the damping sleeve rod slides inside the damping sleeve, which makes the damping movable block slide against the inner wall of the damping sleeve and squeeze the energy-absorbing spring, thereby absorbing the vibration of the two adjacent pipes.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] As attached Figure 1-6 A ventilation pipe design structure that takes civil air defense into consideration is shown, comprising a damping sleeve 1, a damping sleeve rod 2 and two pipe support structures, one end of the damping sleeve rod 2 is arranged inside the damping sleeve 1, and the two pipe support structures are symmetrically installed on one end of the damping sleeve rod 2 and the damping sleeve 1 respectively.

[0023] Specifically, in this structure, the damping sleeve rod 2 is inside the damping sleeve 1, and the two pipe support structures are connected through the damping sleeve 1 and the damping sleeve rod 2. The two pipe support structures clamp and support the civil air defense ventilation duct. The setting of this structure can achieve isolation support between adjacent pipes, avoiding the problem of collision between adjacent pipes due to vibration when the civil air defense project is put into use.

[0024] In this embodiment, as shown in the attached Figure 1 , 2 As shown in , 3, 4, and 5, the pipeline support structure includes a concave frame 3, which is installed on one end of the damping sleeve 2 and the damping sleeve 1, and the two inner walls of the concave frame 3 are provided with mounting grooves 4, and a bidirectional screw rod 5 is arranged inside the mounting groove 4, and two movable seats 6 are arranged outside the bidirectional screw rod 5, and an adjusting block 7 is arranged at one end of the bidirectional screw rod 5, and one end of the bidirectional screw rod 5 is connected to the adjusting block 7, and the two movable seats 6 are both connected to the outer thread of the bidirectional screw rod 5, and the clamping plates 8 at one end of the two movable seats 6 are symmetrically and inclined outwardly, and the clamping plates 8 are inclined at one end of the movable seat 6, and the surface of the clamping plate 8 is provided with a rubber anti-skid pad 9, and the surface of the rubber anti-skid pad 9 is provided with a card groove 10, and the rubber anti-skid pad 9 is pasted on the surface of the clamping plate 8, and the card groove 10 opened on the surface of the rubber protective pad is opened vertically.

[0025] Specifically, as an improved solution of the utility model, the structure can clamp and support square ventilation pipes and circular ventilation pipes, specifically;

[0026] Embodiment 1: When clamping a circular pipe, the circular pipe is placed between multiple clamping plates 8, and the two movable seats 6 outside it are moved closer to or away from each other by rotating the bidirectional screw rod 5. The two movable seats 6 drive the corresponding clamping plates 8 to move closer to or away from each other, and then the distance between the two clamping plates 8 can be adjusted according to the outer diameter of the circular pipe, so that the two clamping plates 8 clamp the outer surface of the circular pipe. The provision of the rubber anti-slip pad 9 can not only protect the circular pipe, but also have a good anti-slip effect, thereby achieving clamping and supporting the circular pipe.

[0027] Embodiment 2: When clamping a square pipe, the same method is used. According to the size of the square pipe, the distance between the two clamping plates 8 is adjusted, and the four corners of the square pipe are aligned with the inside of the vertical slot 10 opened by the corresponding rubber anti-slip pad 9, and the square pipe is clamped by the clamping plate 8, so as to achieve clamping and supporting the square pipe;

[0028] In short, the setting of this structure can facilitate the staff to realize different clamping and supporting methods according to the shape of the civil air defense ventilation pipe, thereby improving the use effect.

[0029] In this embodiment, as shown in the attached Figure 1 , 6 As shown, the outer diameter of the damping sleeve rod 2 is smaller than the inner diameter of the damping sleeve 1, and one end of the damping sleeve rod 2 is slidably connected inside the damping sleeve 1, a damping movable block 11 is arranged inside the damping sleeve 1 at one end of the damping sleeve rod 2, an energy absorbing spring 12 is arranged at the bottom of the damping movable block 11, the outer wall of the damping movable block 11 is slidably connected to the inner wall of the damping sleeve 1, the bottom end of the energy absorbing spring 12 is fixedly installed at the bottom of the inner cavity of the damping sleeve 1, and the top end of the energy absorbing spring 12 is fixedly installed at the bottom of the damping movable block 11.

[0030] Specifically, in this structure, after the two pipes are supported and isolated, the vibration generated by the two pipes is subjected to energy absorption. Since the damping sleeve rod 2 slides inside the damping sleeve 1, and the two pipe support structures clamp and support the two pipes respectively, at this time, the damping sleeve rod 2 and the damping sleeve 1 isolate the two clamped and supported pipes to prevent collision between the two adjacent pipes.

[0031] Once vibration occurs between two adjacent pipes, the damping sleeve rod 2 can slide inside the damping sleeve 1. The damping sleeve rod 2 and the damping sleeve 1 have a certain damping and shock-absorbing effect when sliding, which can weaken part of the vibration. At the same time, the damping movable block 11 can slide against the inner wall of the damping sleeve 1 and squeeze the energy-absorbing spring 12, thereby absorbing the vibration of the two adjacent pipes.

[0032] Working principle of this utility model:

[0033] When the above structure is used, it is first necessary to clamp, support and isolate the two pipes of the civil air defense ventilation pipe to avoid the risk of collision between the two adjacent pipes. Specifically;

[0034] As attached Figure 4 As shown, when clamping the circular pipe, the circular pipe is placed between a plurality of clamping plates 8, and the two movable seats 6 outside the circular pipe are moved closer to or farther from each other by the rotation of the bidirectional screw rod 5, and the two movable seats 6 drive the corresponding clamping plates 8 to move closer to or farther from each other, and then the spacing between the two clamping plates 8 can be adjusted according to the outer diameter of the circular pipe, so that the two clamping plates 8 clamp the outer surface of the circular pipe, and the provision of the rubber anti-skid pad 9 can not only protect the circular pipe, but also play a good anti-skid effect, thereby realizing the clamping support of the circular pipe;

[0035] As attached Figure 3As shown, when clamping the square pipe, the same method is adopted. According to the size of the square pipe, the distance between the two clamping plates 8 is adjusted, and the four corners of the square pipe are aligned with the inside of the vertical card slot 10 opened by the corresponding rubber anti-skid pad 9, and the square pipe is clamped by the clamping plate 8, so as to achieve clamping and supporting the square pipe;

[0036] Therefore, different clamping and supporting modes can be realized according to the shape of the civil air defense ventilation pipe, thereby improving the use effect;

[0037] When the two pipeline support structures clamp and support the two pipelines respectively, the damping sleeve 1 and the damping sleeve rod 2 can separate the two pipelines, thereby avoiding the collision between the two pipelines.

[0038] Once the two pipes vibrate, the damping sleeve rod 2 can slide inside the damping sleeve 1. The damping sleeve rod 2 and the damping sleeve 1 have a certain damping and shock-absorbing effect when sliding, which can weaken part of the vibration. At the same time, the damping movable block 11 can slide against the inner wall of the damping sleeve 1 and squeeze the energy-absorbing spring 12, thereby absorbing the vibration of the two adjacent pipes.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
