Description

Technical Field

[0001] This utility model relates to the field of air leakage prevention technology for tunnel ventilation ducts, specifically an air leakage prevention and reinforcement device for tunnel ventilation ducts. Background Technology

[0002] Ventilation ducts are important equipment used in ventilation systems in enclosed or semi-enclosed spaces such as mines, tunnels, and underground projects. Their main functions include transporting fresh air, diluting and expelling harmful gases, and guiding airflow. They are widely used in underground work sites such as coal mines, metal mines, subway tunnels, and water conservancy projects, and are an important guarantee for safe production.

[0003] The most important aspect of long-distance ventilation is ensuring sufficient airflow to the working face. To guarantee sufficient airflow, minimizing air leakage, especially at the duct joints, is crucial. Currently, the connection between two ducts uses flanges and bolts, resulting in poor sealing. Furthermore, maintenance requires disassembling multiple bolts, which is cumbersome and time-consuming. Therefore, an improved leak-proof reinforcement device for roadway ventilation ducts is needed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a leak-proof reinforcement device for roadway ventilation ducts to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a leak-proof reinforcement device for a roadway ventilation duct, comprising a ventilation duct one and a ventilation duct two, wherein a plug ring is fixedly installed at the end of the ventilation duct two near the ventilation duct one, four plug posts are fixedly installed at the end of the plug ring away from the ventilation duct two, and a sealing gasket is fixedly installed at the end of the plug ring away from the ventilation duct two.

[0006] Preferably, the insert ring is inserted into the inside of the air duct, the sealing gasket abuts against the inside of the air duct, and all four inserts penetrate the sealing gasket and are inserted into the inside of the air duct.

[0007] Preferably, two hanging blocks are fixedly installed on the outside of the first air duct, and two fixing frames are fixedly installed on the outside of the second air duct. A control block is rotatably installed on the outside of each of the two fixing frames, and a hanging ring is rotatably installed inside the control block.

[0008] Preferably, the hanging ring is fastened to the outside of the hanging block.

[0009] Preferably, a threaded cylinder is fixedly installed on the outside of the second air duct, a threaded sleeve is installed on the external thread of the threaded cylinder, a protective cylinder is fixedly installed on the right end of the threaded sleeve, and a retaining ring is fixedly installed on the outside of the first air duct.

[0010] Preferably, the end of the protective cylinder away from the threaded sleeve abuts against the retaining ring, and the protective cylinder is disposed outside the connection between the first air duct and the second air duct.

[0011] Preferably, a limit ring is fixedly installed at the end of the threaded cylinder away from the air duct.

[0012] Compared with the prior art, this utility model provides a leak-proof reinforcement device for tunnel ventilation ducts, which has the following beneficial effects:

[0013] 1. This air duct anti-leakage reinforcement device for the tunnel ventilation duct, by pressing down the control block, makes the hanging ring fasten to the outside of the hanging block. The same applies to the other side, so that the connection between ventilation duct one and ventilation duct two is completely fitted and the installation is completed. At the same time, the sealing gasket is squeezed between the insert ring and ventilation duct one, so that the sealing effect between ventilation duct one and ventilation duct two is better, and gas leakage is avoided.

[0014] 2. Based on this, the present invention protects the hanging block and its connected components by forming a closed space through the threaded sleeve, protective cylinder and retaining ring, so as to avoid accidental contact that may cause the control block to be pressed, thereby causing the hanging ring to detach from the hanging block, and making the structure stable after the connection of the first air duct and the second air duct.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] Example 1:

[0025] Please see Figure 1-4 This utility model provides a technical solution: a tunnel ventilation duct anti-leakage reinforcement device, including a ventilation duct 1 and a ventilation duct 2. A retaining ring 3 is fixedly installed at the end of the ventilation duct 2 near the ventilation duct 1. Four inserts 4 are fixedly installed at the end of the retaining ring 3 away from the ventilation duct 2. A sealing gasket 5 is fixedly installed at the end of the retaining ring 3 away from the ventilation duct 2, so that the sealing effect between the ventilation duct 1 and the ventilation duct 2 is better and gas leakage is avoided.

[0026] Furthermore, the insert ring 3 is inserted into the inside of the air duct 1, the sealing gasket 5 abuts against the inside of the air duct 1, and the four insert pins 4 all penetrate the sealing gasket 5 and are inserted into the inside of the air duct 1, making the connection between the air duct 1 and the air duct 2 more secure and preventing deformation.

[0027] Furthermore, two hanging blocks 6 are fixedly installed on the outside of the ventilation duct 1, and two fixing brackets 7 are fixedly installed on the outside of the ventilation duct 2. Control blocks 8 are rotatably installed on the outside of both fixing brackets 7, and hanging rings 9 are rotatably installed inside the control blocks 8, so as to cooperate with the hanging blocks 6 to complete the installation of ventilation duct 1 and ventilation duct 2.

[0028] Furthermore, the hanging ring 9 is fastened to the outside of the hanging block 6, so that the connection between the air duct 1 and the air duct 2 is completely fitted.

[0029] Example 2:

[0030] Please see Figure 5Furthermore, in conjunction with Embodiment 1, it is further found that a threaded cylinder 10 is fixedly installed on the outside of the second air duct 2, a threaded sleeve 11 is installed on the external thread of the threaded cylinder 10, a protective cylinder 12 is fixedly installed on the right end of the threaded sleeve 11, and a retaining ring 13 is fixedly installed on the outside of the first air duct 1, so that the threaded sleeve 11, the protective cylinder 12 and the retaining ring 13 form a closed space to protect the hanging block 6 and its connected components.

[0031] Furthermore, the end of the protective cylinder 12 away from the threaded sleeve 11 abuts against the retaining ring 13. The protective cylinder 12 is set outside the connection between the air duct 1 and the air duct 2 to protect the hanging block 6 and its connected components, and to prevent accidental pressing of the control block 8.

[0032] Furthermore, a limit ring is fixedly installed at the end of the threaded cylinder 10 away from the air duct 1 to prevent the threaded sleeve 11 from disengaging from the threaded cylinder 10 when it moves to the left.

[0033] In actual operation, when this device is in use, align the centers of air duct 1 and air duct 2, then push air duct 2 to the right, causing the insert ring 3 to move the four insert pins 4 closer to air duct 1. When the insert pins 4 are stuck inside air duct 1 and cannot be moved, rotate air duct 2 to move the four insert pins 4 inside air duct 1 until the four insert pins 4 are inserted into the four insertion holes inside air duct 1. At this point, the positions of air duct 1 and air duct 2 are fixed, and the insert ring 3 is inserted into air duct 1. Inside 1, the control block 8 is then lifted, and the hanging ring 9 is fastened to the outside of the hanging block 6. The control block 8 is then pressed down, so that the hanging ring 9 is fastened to the outside of the hanging block 6. The same applies to the other side, so that the connection between the air duct 1 and the air duct 2 is completely fitted. While the connection between the air duct 1 and the air duct 2 is fitted, the insert ring 3 is inserted deeper into the air duct 1, so that the sealing gasket 5 is squeezed between the insert ring 3 and the air duct 1, so that the sealing effect between the air duct 1 and the air duct 2 is better, and gas leakage is avoided.

[0034] Furthermore, the insertion post 4 corresponds to the insertion hole inside the air duct 1, so that the hanging block 6 on the outside of the air duct 1 and the hanging ring 9 on the outside of the air duct 2 can be quickly positioned, which facilitates quick installation.

[0035] Furthermore, the four inserts 4 and the insert rings 3 are all inserted into the inside of the first air duct 1, making the connection between the first air duct 1 and the second air duct 2 tighter, making the connection between the first air duct 1 and the second air duct 2 straighter, thereby reducing the curvature, effectively reducing wind resistance, reducing the amount of work, and also making the connection between the first air duct 1 and the second air duct 2 more secure, avoiding deformation.

[0036] Furthermore, the end of duct 1 furthest from duct 2 has the same structure as the end of duct 2 closest to duct 1, and similarly, the end of duct 2 furthest from duct 1 has the same structure as the end of duct 1 closest to duct 2, allowing multiple ducts to be connected for greater flexibility.

[0037] Furthermore, after the installation of air duct 1 and air duct 2 is completed, rotate the threaded sleeve 11 to move the protective cylinder 12 to the right until it abuts against the left side of the retaining ring 13. This creates a closed space between the threaded sleeve 11, the protective cylinder 12, and the retaining ring 13, protecting the hanging block 6 and its connected components. This prevents accidental contact that could press the control block 8, causing the hanging ring 9 to detach from the hanging block 6. This ensures that the structure is stable after the connection between air duct 1 and air duct 2.

[0038] Furthermore, a limit ring is fixedly installed at the end of the threaded cylinder 10 away from the retaining ring 13 to prevent the threaded sleeve 11 from disengaging from the threaded cylinder 10 when it moves to the left.
