[0002] Firefighting pipes refer to pipe materials used in firefighting to connect firefighting equipment and devices and to transport firefighting water, gas or other media. Due to special needs, there are special requirements for the thickness and material of firefighting pipes, and they are sprayed with red paint to transport firefighting water. With the rapid development of urban construction, fire safety has attracted more and more attention. As an important facility for firefighting and rescue, the air tightness of firefighting pipes is directly related to the firefighting effect. In the production process of firefighting pipes, air tightness testing is a key link to ensure the quality of pipes. At present, the mainstream firefighting pipe air tightness testing equipment on the market mainly relies on pressure changes or gas flow changes to judge the air tightness of the pipes. Although these devices can realize air tightness testing, they have disadvantages such as low detection accuracy, complex operation and long detection time. Especially in large-scale production lines, the detection efficiency of these devices is difficult to meet the needs of fast and accurate detection.

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The present application embodiment discloses a fire protection pipeline air tightness detection device. Figure 1 , including a mounting plate 1 and a leakage detector 12 mounted on the mounting plate 1, a support seat 4 is provided on the inner side of the mounting plate 1, a plurality of mounting holes 2 are opened on the surface of the mounting plate 1 at equal intervals along the circumferential direction, the mounting plate 1 can be fixed at the detection location in advance by passing bolts through the mounting holes 2, and a plurality of reinforcing rods 3 are connected between the mounting plate 1 and the inner wall of the support seat 4 at equal intervals along the circumferential direction, the reinforcing rods 3 can provide a good supporting effect on the support seat 4, and a gear ring 8 is rotatably installed on the inner wall of the support seat 4, and a rotating disk 5 is fixed to the end of the gear ring 8 away from the support seat 4.

[0020] like Figure 2 As shown, a fixing plate 9 is fixed to the top of the support seat 4, and a gear 11 adapted to the ring gear 8 is provided on the inner side of the fixing plate 9, and a protective cover 10 adapted to the gear 11 is fixed to the inner wall of the fixing plate 9. The protective cover 10 is arranged on the outside of the top of the gear 11 to provide protection. A servo motor is installed on the outer wall of the fixing plate 9, and the output end of the servo motor passes through the inner wall of the fixing plate 9 and is transmitted to the gear 11. As the gear 11 rotates, it will mesh with the ring gear 8, and then drive the ring gear 8 to drive the rotating disk 5 to rotate.

[0021] like Figure 3 As shown, a group of clamping plates 16 are equidistantly provided on the inner wall of the rotating disk 5 along the circumferential direction. The clamping plates 16 are arranged in an arc shape to better fit the outer wall of the fire-fighting pipe. A positioning cavity 13 is opened inside the rotating disk 5, and the positioning cavity 13 extends to the inside of the supporting seat 4. One end of the fire-fighting pipe to be inspected can be placed in the positioning cavity 13 in advance. Since a group of threaded rods 15 are threadedly connected to the outer wall of the rotating disk 5, and one end of the threaded rod 15 extends into the positioning cavity 13 and is movably connected to the clamping plates 16, the threaded rods 15 can be rotated to push the clamping plates 16 close to the fire-fighting pipe and clamp it, thereby facilitating subsequent air tightness detection.

[0022] Support slide bars 6 are symmetrically welded on both sides of the inner wall of the fixed plate 9, a connecting frame 14 is welded on one end of the support slide bar 6 away from the fixed plate 9, a sliding block 7 is slidably installed on the support slide bar 6, and since the sliding block 7 is connected to the gas leakage detector 12 by screws, the distance of the gas leakage detector 12 to detect the surface of the fire protection pipe can be adjusted by adjusting the sliding distance of the sliding block 7 on the support slide bar 6.

[0023] The implementation principle of a fire-fighting pipe air tightness detection device in an embodiment of the present application is as follows: when in use, the mounting plate 1 is fixed at the detection location in advance by passing bolts through the mounting hole 2, and the support seat 4 is well supported by the setting of the reinforcing rod 3 to ensure the overall stability, and then one end of the fire-fighting pipe to be detected is extended to the inside of the positioning cavity 13, and the adjusting threaded rod 15 is used to push the clamping plate 16 close to the outer wall of the fire-fighting pipe to fix it. At this time, the sliding block 7 on the sliding support slide rod 6 can be used to adjust the distance of the leakage detector 12 from the surface of the fire-fighting pipe. The gear 11 can also be driven by a servo motor to rotate and engage with the gear ring 8, and the rotating disk 5 can be driven to rotate to drive the internal fire-fighting pipe to change circumferentially, thereby facilitating all-round detection of the outer wall of the fire-fighting pipe to avoid local leakage.
