Description

Technical Field

[0001] This utility model relates to the technical field of ventilation systems for civil defense projects, and in particular to a civil defense ventilation duct structure. Background Technology

[0002] In civil defense engineering, the ventilation system is a critical lifeline system for ensuring the survival of personnel inside the facility during wartime. It is responsible for air regeneration, filtration, and ventilation in a sealed, isolated environment, and for preventing the intrusion of harmful external agents. As the channel for air transport, the airtightness, robustness, and ease of installation of ventilation ducts directly affect the effectiveness and reliability of the entire ventilation system. Traditional on-site fabrication and installation methods suffer from low efficiency and difficulty in guaranteeing quality; therefore, the use of standardized prefabricated ducts has become an industry trend.

[0003] Currently, the on-site installation of prefabricated air-raid shelter ducts mainly uses flange connections. This involves welding or riveting angle steel flanges or common plate flanges to the ends of one section of the duct. During installation, the flanges of the two duct sections are aligned, bolts are inserted into the bolt holes, and nuts are tightened one by one. This method has the following prominent problems in practical applications:

[0004] Alignment is difficult and inefficient: Due to the large size and weight of the ductwork, multiple workers are required to work together to precisely align the bolt holes of the two duct sections when connecting them in the air. This process is time-consuming and labor-intensive, especially in confined spaces or poorly lit interiors, where alignment is even more difficult and installation efficiency is extremely low.

[0005] Connection quality relies on manual labor and is prone to inconsistency: bolts need to be tightened evenly in a diagonal sequence to ensure uniform pressure on the gasket and achieve a seal. If workers do not operate according to regulations, uneven stress on the flange surface may occur, causing leakage at the connection, seriously affecting the system's sealing performance and posing a safety hazard.

[0006] Safety concerns: There are safety risks for workers when working at heights, particularly when aligning and tightening bolts. Additionally, the heavy physical labor increases the workload for workers.

[0007] Lack of effective initial positioning guidance: The existing flange connection method itself does not have effective guidance and pre-positioning functions, and relies entirely on the experience and skills of workers for blind alignment, which is one of the root causes of the difficulty in alignment. Utility Model Content

[0008] In summary, the core problem with the existing installation and connection methods for civil defense ventilation ducts is the lack of a fast and accurate initial positioning mechanism and an efficient and reliable locking mechanism. This results in the installation process relying too heavily on manpower and experience, leading to defects such as low efficiency, poor quality control, and insufficient safety.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] This utility model discloses a civil defense ventilation duct structure, including a connector and a duct structure. The duct structures are connected to each other by the connector, which is located on one side of the duct structure. The connector is equipped with a positioning structure aligned with the duct structure. The inner side of the connector is equipped with a locking structure that is fixed to the duct structure. Both the inner side of the duct structure and the inner side of the connector are equipped with a sealing structure.

[0011] As a preferred technical solution of this utility model, the locking structure includes a lock cylinder installed inside the duct structure and a connecting piece inside the connector. The lock cylinder has a slot installed inside and a lock hole installed on it. The slot and the connecting piece are correspondingly arranged, and the connecting piece has a through hole corresponding to the lock hole.

[0012] As a preferred technical solution of this utility model, the positioning structure includes mounting holes installed on the duct structure and positioning pins on the connector. The mounting holes and positioning pins are correspondingly arranged, and the mounting holes and positioning pins are distributed in a ring on the surface of the duct structure and the connector.

[0013] As a preferred technical solution of this utility model, the sealing structure includes a gasket installed on the duct structure and a sealing ring on the connector. The duct structure is provided with a recessed hole for placing the gasket, and the connector is provided with a groove. The positioning pins are evenly distributed on the groove.

[0014] As a preferred technical solution of this utility model, the sealing ring is made of elastic rubber material and has an inner and outer two-layer structure.

[0015] As a preferred embodiment of this utility model, the inner sealing ring is used to connect the gasket of the duct structure to the inner side of the connector, and the outer sealing ring is used to connect the duct structure to the outer side of the connector.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. Enables rapid and accurate blind docking, doubling installation efficiency.

[0018] This invention, through its locking and positioning structures, enables the connectors and ductwork to achieve axial alignment and angle correction when they are close together, eliminating the need for manual, precise visual alignment and position adjustments. This simplifies the previously cumbersome aerial alignment process into a highly efficient "insertion" operation, significantly reducing single-point connection time and increasing installation efficiency several times over.

[0019] 2. Ensure consistent and highly reliable connection quality.

[0020] The use of gaskets and sealing rings ensures uniform circumferential stress at the connection interface, achieving optimal sealing performance in one step. This process eliminates sealing issues caused by differences in manual operation sequence and tightening torque, guaranteeing consistent and reliable high-sealing performance at every connection point and greatly improving the overall safety of the system.

[0021] 3. Significantly reduces work intensity and operational risks.

[0022] The new solution greatly simplifies the physical exertion required during installation. This not only significantly reduces the workload of workers but also fundamentally reduces safety risks such as instability and falls from heights caused by strenuous operation, thus improving the working environment.

[0023] 4. Reduce reliance on skills and achieve standardized operations.

[0024] This invention transforms complex operations that previously relied on individual worker experience and skills into a simple, standardized process. Even less experienced operators can quickly complete high-quality connections by following the procedures, reducing reliance on highly skilled workers and facilitating standardized project management and personnel training.

[0032] Example 1

[0033] like Figure 1-2 As shown, this utility model provides a civil defense air duct structure, including a connector 1 and an air duct structure 2. The air duct structures 2 are connected by the connector 1. The connector 1 is located on one side of the air duct structure 2. A positioning structure 3 aligned with the air duct structure 2 is installed on the connector 1. A locking structure 4 fixed to the air duct structure 2 is installed on the inner side of the connector 1. A sealing structure 5 is installed on the inner side of both the air duct structure 2 and the connector 1.

[0034] Specifically, in use, the connector 1 is aligned with the duct structure 2 by the positioning structure 3, and then the connector 1 is fixed to the duct structure 2 by the locking structure 4.

[0035] The locking structure 4 includes a lock cylinder 6 installed inside the duct structure 2 and a connecting piece 7 inside the connector 1. A slot 8 is installed inside the lock cylinder 6, and a lock hole 9 is installed on the lock cylinder 6. The slot 8 is correspondingly set with the connecting piece 7, and a through hole corresponding to the lock hole 9 is installed on the connecting piece 7.

[0036] During the docking process, the connecting piece 7 is inserted into the slot 8 on the lock cylinder 6, and then the fastening bolt is inserted into the lock hole 9 for fixation, so that the connecting piece and the air duct can achieve axial alignment and angle correction, and achieve structural stability.

[0037] The positioning structure 3 includes mounting holes 10 installed on the duct structure 2 and positioning pins 11 on the connector 1. The mounting holes 10 and positioning pins 11 are correspondingly provided, and the mounting holes 10 and positioning pins 11 are distributed in a ring on the surface of the duct structure 2 and the connector 1.

[0038] Insert the positioning pin 11 into the mounting hole 10 on the duct structure 2. By using the efficient "insertion" operation, the single-point connection time is significantly shortened, and the installation efficiency is improved several times.

[0039] The sealing structure 5 includes a gasket 12 installed on the duct structure 2 and a sealing ring 13 on the connector 1. The duct structure 2 has a recessed hole 14 for placing the gasket 12, and the connector 1 has a groove 15. The positioning pins 11 are evenly distributed on the groove 15. The sealing ring 13 is made of elastic rubber material and has an inner and outer double-layer structure.

[0040] The inner sealing ring 13 is used to connect the gasket 12 of the duct structure 2 to the inner side of the connector 1, and the outer sealing ring 13 is used to connect the duct structure 2 to the outer side of the connector 1. This ensures that the circumferential force on the connection interface is uniform, thereby achieving the best sealing effect in one go.

[0041] In summary, this utility model fundamentally revolutionizes the installation mode of air ducts through technical means, making them more efficient, reliable, and safe, and providing core technical support for the rapid and high-quality construction of large-scale ventilation systems.
