Description

Technical Field

[0001] This utility model belongs to the field of civil defense pipeline sealing technology, and in particular relates to a civil defense pipeline sealing device. Background Technology

[0002] Civil defense projects play a crucial role in national defense security and civilian protection. Among them, civil defense pipelines are an important component, and their sealing and stability directly affect the protective effect of civil defense projects. Civil defense pipeline sealing devices, as important equipment to ensure the normal operation and protective performance of civil defense pipelines, play an irreplaceable role in preventing external pollutants and shock waves from entering the interior of civil defense projects, and ensuring the safety and stability of the internal environment.

[0003] However, existing civil defense pipeline sealing devices have many shortcomings in practical applications. The fixing and sealing functions of some devices are independent of each other, and the operation is cumbersome. This not only increases the workload of construction workers, but also prolongs the installation time, making it difficult to meet the needs of rapid installation in emergency situations and reducing the work efficiency of workers.

[0004] To address these issues, we provide a device for sealing civil defense pipelines. Utility Model Content

[0005] The purpose of this utility model is to provide a civil defense pipeline sealing device, which solves the problem of cumbersome operation caused by the independent fixing and sealing functions of the existing civil defense pipeline sealing device through the cooperation of the first adjustment mechanism, the second adjustment mechanism and the sealing component.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a sealing device for civil defense pipelines, comprising a first fixing sleeve, a second fixing sleeve disposed on the top of the first fixing sleeve, a first adjusting mechanism disposed between the first and second fixing sleeves, and a second adjusting mechanism disposed on the surface of the first fixing sleeve. A sealing component is fixedly connected to one end of the second adjusting mechanism. The first adjusting mechanism includes a first threaded tube, a first threaded rod threadedly connected to the inner wall of the first threaded tube, a connecting block fixedly connected to the top of the first threaded rod, one side of the connecting block fixedly connected to the second fixing sleeve, and a first bevel gear fixedly connected to the bottom of the first threaded tube. The second adjusting mechanism includes a support block, which is fixed to... On one side of the second fixed sleeve, a second threaded tube is movably connected to the surface of the support block via a bearing. A second threaded rod is threadedly connected to the inner wall of the second threaded tube. One end of the second threaded rod is fixedly connected to the sealing component. A second bevel gear that meshes with the first bevel gear is fixedly sleeved on the surface of the second threaded tube. By setting up the first fixed sleeve, the second fixed sleeve, the first adjustment mechanism, and the second adjustment mechanism, the integrated linkage of pipe fixing and sealing functions is realized. Rotating the second threaded tube can simultaneously drive the first fixed sleeve and the second fixed sleeve to clamp the pipe and push the sealing component to achieve a seal, simplifying the operation process, significantly improving work efficiency, and meeting the needs of rapid installation in emergency situations.

[0008] The present invention is further configured such that an installation sleeve is fixedly sleeved on the surface of the first threaded pipe, and one side of the installation sleeve is fixedly connected to the first fixed sleeve.

[0009] The present invention is further configured such that a knob is fixedly connected to one end of the second threaded tube, and the surface of the knob is provided with anti-slip texture.

[0010] The present invention is further configured such that the inner walls of the first threaded pipe and the second threaded pipe are provided with triangular self-locking threads, and the surfaces of the first threaded rod and the second threaded rod are provided with triangular self-locking threads. The triangular self-locking threads on the inner walls of the first threaded pipe and the second threaded pipe cooperate with each other to form a self-locking structure. After the pipe is fixed and sealed, the threads are prevented from loosening due to external force, ensuring that the device maintains a stable fixing and sealing effect for a long time and enhancing the safety of the device.

[0011] The present invention is further configured such that a limiting groove is fixedly connected to the surface of the first fixed sleeve, a limiting block is slidably connected to the inner wall of the limiting groove, and one side of the limiting block is fixedly connected to the second fixed sleeve.

[0012] The present invention is further configured such that a limiting plate is fixedly connected to one side of the bottom of the first fixing sleeve, a limiting rod is provided through one side of the limiting plate, a connecting plate is fixedly connected to one end of the limiting rod, and a sealing member is fixedly connected to one side of the connecting plate.

[0013] The present invention is further configured such that a slot is provided at the top of the first fixing sleeve, and a plug plate that cooperates with the slot is fixedly connected to the bottom of the second fixing sleeve.

The combined design of the sealing plate, sealing head, sealing groove and sealing gasket of the sealing component can tightly fit the civil defense pipeline. The sealing gasket fills the gap between the sealing groove and the civil defense pipeline, effectively preventing external pollutants, shock waves and other objects from entering the civil defense project, and significantly improving the sealing performance and protection effect of the civil defense pipeline sealing device.

[0015] The present invention has the following beneficial effects.

[0016] 1. In this utility model, while the second threaded pipe is rotated to fix the pipeline, the second threaded rod drives the sealing component to move synchronously until it makes close contact with the civil defense pipeline to complete the sealing. There is no need to perform fixing and sealing operations separately. The method of fixing and sealing in tandem not only shortens the construction time, but also ensures the precise coordination of the two key steps. In the construction and maintenance of civil defense projects, pipeline treatment work can be completed quickly and effectively, providing a solid guarantee for the safety of the project.

[0017] 2. By rotating the second threaded pipe, this utility model utilizes the principles of thread transmission and gear meshing to drive the second threaded rod to the second bevel gear, which in turn links the first bevel gear, causing the first threaded pipe and the first threaded rod to move. This enables the second fixed sleeve to clamp and fix the pipe in conjunction with the first fixed sleeve. The entire process requires only one operation, avoiding complex multi-step operation procedures, greatly reducing construction difficulty and manual labor. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1

[0028] Please see Figure 1-6 This utility model is a sealing device for civil defense pipelines, including a first fixed sleeve 1, a second fixed sleeve 2 at the top of the first fixed sleeve 1, a first adjusting mechanism 3 between the first fixed sleeve 1 and the second fixed sleeve 2, a second adjusting mechanism 4 on the surface of the first fixed sleeve 1, and a sealing component 5 fixedly connected to one end of the second adjusting mechanism 4; the first adjusting mechanism 3 includes a first threaded tube 31, a first threaded rod 32 threadedly connected to the inner wall of the first threaded tube 31, a connecting block 33 fixedly connected to the top of the first threaded rod 32, one side of the connecting block 33 fixedly connected to the second fixed sleeve 2, and a first bevel gear 34 fixedly connected to the bottom of the first threaded tube 31; the second adjusting mechanism 4 includes a support block 41, the support block 41 fixed to one side of the second fixed sleeve 2, the second threaded tube 42 movably connected to the surface of the support block 41 through a bearing, the second threaded rod 43 threadedly connected to the inner wall of the second threaded tube 42, one end of the second threaded rod 43 fixedly connected to the sealing component 5, and a second bevel gear 44 meshing with the first bevel gear 34 fixedly sleeved on the surface of the second threaded tube 42.

[0029] Specifically, by setting up a first fixing sleeve 1, a second fixing sleeve 2, a first adjusting mechanism 3, and a second adjusting mechanism 4, the integrated linkage of pipe fixing and sealing functions is realized. Rotating the second threaded pipe 42 can simultaneously drive the first fixing sleeve 1 and the second fixing sleeve 2 to clamp the pipe and push the sealing component 5 to achieve sealing, simplifying the operation process, significantly improving work efficiency, and meeting the needs of rapid installation in emergency situations.

[0030] Example 2

[0031] Please see Figure 1-6 Based on Embodiment 1, an installation sleeve is fixedly fitted onto the surface of the first threaded tube 31, with one side of the installation sleeve fixedly connected to the first fixed sleeve 1. A knob 441 is fixedly connected to one end of the second threaded tube 42, and the surface of the knob 441 is provided with anti-slip texture. The inner walls of both the first threaded tube 31 and the second threaded tube 42 are provided with a triangular self-locking thread I. The surfaces of both the first threaded rod 32 and the second threaded rod 43 are provided with a triangular self-locking thread II. A limit groove 11 is fixedly connected to the surface of the first fixed sleeve 1, and a limit block 12 is slidably connected to the inner wall of the limit groove 11. One side of the limit block 12 is connected to the second fixed sleeve. 2. Fixed connection: A limiting plate 13 is fixedly connected to one side of the bottom of the first fixed sleeve 1. A limiting rod 14 is provided through one side of the limiting plate 13. A connecting plate 15 is fixedly connected to one end of the limiting rod 14. One side of the connecting plate 15 is fixedly connected to the sealing component 5. A slot 16 is provided at the top of the first fixed sleeve 1. An insert plate 17 that mates with the slot 16 is fixedly connected to the bottom of the second fixed sleeve 2. The sealing component 5 includes a sealing plate 51. A sealing head 52 is fixedly connected to one side of the sealing plate 51. A sealing groove 53 is provided on one side of the sealing head 52. A sealing gasket 54 is fixedly connected to the inner wall of the sealing groove 53.

[0032] Specifically: The mounting sleeve on the surface of the first threaded pipe 31 is fixedly connected to the first fixed sleeve 1, providing a stable support structure for the first threaded pipe 31. During the rotation of the first threaded pipe 31, which drives the first threaded rod 32 to move, swaying is reduced, ensuring that the first fixed sleeve 1 and the second fixed sleeve 2 smoothly clamp the pipe, improving the overall reliability of the device. The knob 441 at one end of the second threaded pipe 42, with its anti-slip texture, allows construction personnel to rotate the second threaded pipe 42 more easily and stably, reducing operational difficulty and reducing the risk of slippage during prolonged or emergency operations. To reduce hand fatigue and improve operational accuracy and efficiency, the triangular self-locking threads on the inner walls of the first threaded pipe 31 and the second threaded pipe 42, in conjunction with the triangular self-locking threads on the surfaces of the first threaded rod 32 and the second threaded rod 43, form a self-locking structure. After the pipe is fixed and sealed, this prevents the threads from loosening due to external forces, ensuring that the device maintains a stable fixing and sealing effect for a long time, thus enhancing the safety of the device. The limiting groove 11 on the surface of the first fixed sleeve 1 is slidably connected to the limiting block 12 of the second fixed sleeve 2, limiting the offset of the second fixed sleeve 2 during its up-and-down movement. This ensures that the second fixing sleeve 2 can accurately cooperate with the first fixing sleeve 1 to clamp the pipe, while improving the overall structural stability and reliability of the device. The structure composed of the limiting plate 13, limiting rod 14 and connecting plate 15 at the bottom of the first fixing sleeve 1 guides and limits the movement of the sealing component 5, so that the sealing component 5 can maintain linear movement when it is close to the civil defense pipe for sealing, ensuring the accuracy of the sealing position, thereby improving the sealing effect and sealing performance. The slot 16 at the top of the first fixing sleeve 1 cooperates with the insert plate 17 at the bottom of the second fixing sleeve 2, which plays a role in the installation process. The precise positioning allows the second fixing sleeve 2 to be quickly and accurately installed onto the first fixing sleeve 1, while also enhancing the connection strength between the first fixing sleeve 1 and the second fixing sleeve 2, thus improving the overall stability of the device. The combined design of the sealing plate 51, sealing head 52, sealing groove 53, and sealing gasket 54 of the sealing component 5 can tightly fit the civil defense pipeline. The sealing gasket 54 fills the gap between the sealing groove 53 and the civil defense pipeline, effectively preventing external pollutants, shock waves, etc. from entering the interior of the civil defense project, significantly improving the sealing performance and protective effect of the civil defense pipeline sealing device.

[0033] The working principle of this utility model is as follows: The user places the pipe between the first fixed sleeve 1 and the second fixed sleeve 2. The user rotates the second threaded pipe 42, the second threaded rod 43 drives the second bevel gear 44 to rotate, the second bevel gear 44 drives the first bevel gear 34 to rotate, the first bevel gear 34 drives the first threaded pipe 31 to rotate, the first threaded pipe 31 drives the first threaded rod 32 to move downward, the first threaded rod 32 drives the connecting block 33 to move downward, the connecting block 33 drives the second fixed sleeve 2 to move downward, the second fixed sleeve 2 cooperates with the first fixed sleeve 1 to clamp and fix the pipe. When the second threaded pipe 42 rotates, it drives the second threaded rod 43 to move towards the side of the civil defense pipe, the second threaded rod 43 drives the sealing part 5 to move until the sealing part 5 is in close contact with the civil defense pipe, so as to achieve the coordinated fixing and sealing.
