Description

Technical Field

[0001] This utility model relates to the technical field of fire protection acceptance auxiliary devices, specifically to a fire protection maintenance engineering testing and acceptance auxiliary device. Background Technology

[0002] Fire safety acceptance refers to the fire department's inspection and verification of the fire safety of enterprises and institutions upon completion and operation. Construction units require the fire department to conduct safety inspections and checks during fire safety acceptance. Among the tests conducted on the fire water system, fire hydrant pressure testing nozzles are needed to perform static and dynamic pressure tests on the hydrants. Existing pressure testing nozzles typically use a sliding groove on the side of the hydrant to rotate and engage a side locking block. However, this structure is prone to misoperation, leading to improper engagement, leaks, and bursts during pressure testing. Furthermore, prolonged use of this locking structure may result in water seepage, affecting the pressure test results. Therefore, an auxiliary device for fire safety maintenance engineering inspection and acceptance is proposed. Utility Model Content

[0003] The purpose of this utility model is to solve the problem of auxiliary devices for testing and acceptance of fire protection maintenance projects. This utility model provides an auxiliary device for testing and acceptance of fire protection maintenance projects.

Therefore, they should not be construed as limitations on this utility model.

[0025] like Figures 1 to 2As shown, a fire protection maintenance engineering inspection and acceptance auxiliary device includes a fire cabinet 1, which is a rectangular box with a hollowed-out side. A fire hydrant 2 with water supply is installed inside the fire cabinet 1. A pressure test gun body 3 with a conical water gun is installed on the side of the fire hydrant 2. A pressure gauge 301 with pressure measurement is installed on the side of the pressure test gun body 3. A manual valve 302 is fixedly installed on the side of the pressure test gun body 3 away from the fire hydrant 2. A positioning component 4 with positioning and locking is provided between the fire hydrant 2 and the pressure test gun body 3. An auxiliary component 5 with sealing function is provided on the side of the positioning component 4.

[0026] Specifically, the positioning component 4 can be used to position and lock the pressure test gun body 3 onto the side of the fire hydrant 2, ensuring that it is properly locked in place and will not be misaligned. Static and dynamic testing can be performed through the manual valve 302. The auxiliary component 5 can enhance the sealing between the pressure test gun body 3 and the fire hydrant 2 during testing to prevent water leakage.

[0027] like Figures 2-4 As shown, the positioning component 4 includes a fixing block 401 fixedly sleeved on the side of the fire hydrant 2. The fixing block 401 is an annular block. An mounting groove 402 is equidistantly arranged in a circumferential array on the side of the fixing block 401. The mounting groove 402 is a folded rectangular groove with an "L"-shaped cross-section. An mounting block 404 is movably installed inside the mounting groove 402 and is fixedly connected to the side of the pressure testing gun body 3. The mounting block 404 is an arc-shaped block with an "L"-shaped cross-section. A slot 403 penetrating the fixing block 401 is formed inside the mounting groove 402. The slot 403 is a cylindrical groove with a convex cross-section. A movable part is formed on the side of the mounting block 404 corresponding to the slot 403. The movable groove 405 is a cylindrical groove with a convex cross-section. A locking block 406 is movably installed inside the movable groove 405 and extends and engages with the inside of the locking groove 403. The locking block 406 is a cylindrical block with a convex cross-section and a cylindrical groove on its side. A constraint rod 407 is movably installed inside the locking block 406 and is fixedly connected to the inner wall of the movable groove 405. The constraint rod 407 is a cylindrical rod. A support cylinder 408 is fixedly connected between the side of the locking block 406 and the inner wall of the movable groove 405 and is movably sleeved on the side of the constraint rod 407. The support cylinder 408 is a spring steel cylinder with a continuous "W" shaped cross-section.

[0028] Specifically, the locking block 406 is constrained by the constraint rod 407 and slides inside the movable groove 405. The support cylinder 408 provides elastic support for the locking block 406. When the test gun body 3 is installed, the mounting block 404 is first installed inside the mounting groove 402 and then continues to slide and lock. Similarly, the locking block 406 is squeezed and slides into the movable groove 405. When the locking block 406 slides to the position of the slot 403, the locking block 406 is supported by the support cylinder 408 and locks it into the position inside the slot 403, which provides positioning constraint for the mounting block 404, thus completing the accurate positioning and fixing of the test gun body 3 and preventing it from loosening due to external forces.

[0029] like Figure 3 - Figure 5 As shown, the auxiliary component 5 includes a mating groove 501 formed on the inner wall of the movable groove 405, and the mating groove 501 penetrates the mounting block 404 and the test gun body 3 to the inner side of the test gun body 3. The mating groove 501 is a rectangular groove with a "Z" shaped cross section. A mating rod 502 is movably installed inside the mating groove 501, and both ends of the mating rod 502 extend to the inside of the movable groove 405 and the inner side of the test gun body 3. The mating rod 502 is fixedly connected to the side of the locking block 406. The mating rod 502 is a rectangular rod with a "Z" shaped cross section. A sealing block 504 is fixedly installed at the position of the mating rod 502 corresponding to the inner side of the test gun body 3, and the sealing block 504 fits against the inner side of the test gun body 3. A support block 503 is fixedly connected between the side of the mating rod 502 and the inner wall of the mating groove 501. The support block 503 is an "O" shaped block made of spring steel.

[0030] Specifically, the set mating rod 502 can be driven to move as the locking block 406 moves. When the locking block 406 slides inside the movable groove 405, the mating rod 502 can drive the sealing block 504 to fit tightly against the side of the fire hydrant 2. When the locking block 406 is inside the locking groove 403, it can still drive the sealing block 504 to fit against the side of the fire hydrant 2, and play a role in limiting the sealing block 504.

[0031] In summary: The positioning component 4 effectively positions the pressure testing gun body 3 during installation. After positioning, a limiting operation can be performed to prevent poor clamping and loosening during manual installation of the pressure testing gun body 3, which could lead to water leakage and bursting during water pressure testing. The auxiliary component 5, when the positioning component 4 is in place, has its internal sealing block 504 attached to the side of the fire hydrant 2, enhancing the seal between the pressure testing gun body 3 and the fire hydrant 2. Sealing can still be performed after positioning, further reducing water leakage during water pressure testing of the pressure testing gun body 3 and improving the accuracy of the pressure test results.
