Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting collecting pipe detection, in particular to a non-destructive detection device for fire-fighting collecting pipes. Background Art

[0002] Fire manifolds are a crucial component of firefighting systems. Their primary function is to centralize and distribute firefighting water to various firefighting facilities (such as sprinklers and fire hydrants), ensuring rapid and effective delivery of sufficient water volume and pressure in the event of a fire. Manifolds also play a crucial protective role in firefighting systems, ensuring the proper functioning of various firefighting equipment in the event of a fire. Currently, inspection of firefighting manifolds relies primarily on traditional methods, including visual inspection, pressure testing, and partial disassembly. While these methods can detect leaks, corrosion, and other potential hazards in pipes to a certain extent, they also have numerous shortcomings. First, visual inspections require a high level of operator expertise and experience, making them prone to missed inspections. Second, partial disassembly is not only time-consuming but can also cause damage to the piping system.

[0003] During the use of the detection device, since the fire collecting pipe has been fixedly installed and has a long service life, it is necessary to detect whether the fire collecting pipe is leaking. If the fire collecting pipe is disassembled for detection, it will not only waste time but also delay its use. Utility Model Content

[0024] Example 1: Please refer to Figures 1 to 4 :

[0025] The utility model proposes a nondestructive testing device for fire-fighting manifolds, comprising: a fixing frame 1; two threaded holes are provided on the upper end of the fixing frame 1; a shaft hole is provided in the middle of the fixing frame 1; a base 101 is fixedly installed on the left side wall of the fixing frame 1, and a groove is provided on the upper end of the base 101, a small motor 102 is fixedly installed in the groove of the base 101, a rotating shaft on the small motor 102 passes through the shaft hole of the fixing frame 1, a circle of saw teeth 103 is fixedly installed on the rotating shaft of the small motor 102, the saw teeth 103 are engaged with the tooth grooves 304 on the detection ring 302, and the saw teeth 103 on the rotating shaft of the small motor 102 will rotate when the small motor 102 is started, driving the detection ring 302 to rotate slowly. When the fire-fighting manifold is detected, During the process, when encountering the fixed bracket of the fire collecting pipe, slowly rotate the detection ring 302 and the detection plate 306, and move the notch of the detection ring 302 from the bracket of the fire collecting pipe to prevent the detection ring 302 from being blocked by the bracket and unable to move. A positioning hole 104 is opened in the middle of the lower end of the fixed frame 1, and a threaded rod 2 is fixedly installed in the middle of the lower end of the fixed frame 1; the inner side wall of the fixed frame 1 is fixedly installed with mutually symmetrical stabilizing plates 3, and the outer end of the stabilizing plate 3 is fixedly installed with two bolts, and the bolts on the stabilizing plate 3 pass through the threaded holes on the fixed frame 1. The stabilizing plate 3 is fixedly installed on the fixed frame 1 with bolts, and the stabilizing plate 3 and the track plate 301 are fixedly restricted to prevent the track plate 301 from moving when touched.

[0026] Among them, the top of the threaded rod 2 is fixedly installed with a connecting head 201, and the threaded rod 2 is rotatably installed with a hand-held threaded barrel 202. When the fixed fire collecting pipe needs to be inspected, both hands grasp the threaded rod 2 and the hand-held threaded barrel 202 respectively. According to the height of the fire collecting pipe installation, grasp the threaded rod 2 and rotate the hand-held threaded barrel 202 to move up and down, adjust the position of the upper detection ring 302 and the detection plate 306, grasp the hand-held threaded barrel 202, put the detection ring 302 and the detection plate 306 on the fire collecting pipe and move it to inspect the fire collecting pipe. The lower end of the hand-held threaded barrel 202 is fixedly installed with mutually symmetrical anti-slip rings 203. Grab the hand-held threaded barrel 202 with your hand, and hold the hand between the two anti-slip rings 203. A positioning ring 204 is rotatably installed on the connecting head 201. The connecting head 201 passes through the positioning hole 104, and then is rotatably installed on the connecting head 201 with the positioning ring 204. At this time, the positioning ring 204 will be installed in the positioning hole 104.

[0027] Among them, the track plate 301 is fixedly installed at one end opposite to the two stabilizing plates 3, and a rotating detection ring 302 is installed on the track plate 301. Grab the handheld threaded cylinder 202 and move it upward. Put it on the fire collection pipe from the notch of the detection ring 302, and then grab the handheld threaded cylinder 202 to move the detection plate 306. When the fire collection pipe leaks, the leaked water will be sprayed on the detection plate 306. At this time, the fire collection pipe will leak. At the same time, the leakage sensor 307 can also detect the leakage of the fire collection pipe. A ring-shaped track hole 303 is opened on the detection ring 302. The track plate 301 is slidably installed in the track hole 303. When the detection ring 302 rotates, the track hole 303 on the detection ring 302 rotates on the track plate 301 , restricted by the track plate 301, the detection ring 302 will not deviate when it rotates and moves, and tooth grooves 304 are evenly opened on the side walls of the outer end of the detection ring 302. Three ear plates 305 are fixedly installed on the two side walls of the detection ring 302. The middle parts of the three ear plates 305 are respectively rotated and inserted with penetrating screws. The screws on the ear plates 305 are rotated and inserted on the detection plate 306 to temporarily fix the detection plate 306. The detection plate 306 is installed on the inner concave surface of the detection ring 302, and a leakage sensor 307 is fixedly installed at the lower end of the detection ring 302. The leakage sensor 307 can help detect whether the liquid is leaking. The leakage sensor 307 can detect leakage at the early stage of the problem and take timely measures to avoid greater losses.

[0028] Example 2, based on Example 1, Figure 1 and Figure 4 As shown, symmetrical stabilizing plates 3 are fixedly installed on the inner wall of the fixing frame 1, and two bolts are fixedly installed on the outer end of the stabilizing plate 3. The threaded holes and bolts on the fixing frame 1 are deleted, and then the stabilizing plate 3 is fixedly welded to the fixing frame 1 to firmly restrict the stabilizing plate 3 and the track plate 301. In this way, the track plate 301 will not move when touched or hit, thereby avoiding the loosening of the bolts due to long-term use and saving the cost of parts.

[0029] The working principle of this embodiment is as follows: when the fixed fire collection pipe needs to be inspected, the threaded rod 2 and the handheld threaded barrel 202 are grasped by both hands respectively. According to the height of the fire collection pipe installation, the threaded rod 2 is grasped and the handheld threaded barrel 202 is rotated to move up and down, and the position of the upper detection ring 302 and the detection plate 306 are adjusted. The handheld threaded barrel 202 is grasped and moved upward, and is put on the fire collection pipe through the notch of the detection ring 302. Then, the handheld threaded barrel 202 is grasped and the detection ring 302 and the detection plate 306 are moved to inspect the fire collection pipe. The saw teeth 103 are aligned with the tooth grooves 306 on the detection ring 302. 4 rotates and engages, and the saw teeth 103 on the rotating shaft of the small motor 102 are started to rotate, driving the detection ring 302 to rotate slowly. When encountering the fixed bracket of the fire collection pipe during the detection process of the fire collection pipe, the detection ring 302 and the detection plate 306 are slowly rotated to move the notch of the detection ring 302 from the bracket of the fire collection pipe to prevent the detection ring 302 from being blocked by the bracket and unable to move. When the fire collection pipe leaks, the leaked water will be sprayed on the detection plate 306, and the fire collection pipe will leak. At the same time, the leakage sensor 307 can also detect the leakage of the fire collection pipe.
