[0030] Example 1

[0031] Refer to the attached Figure 1-3 A braided composite pipe leak detection device of the present embodiment includes a leak detection box 100, a rotating arm 200, a frame 300 and a pipe clamp 400. The frame 300 is provided with the leak detection box 100 and the rotating arm 200, and the rotating arm 200 is provided with the pipe clamp 400. Water is provided in the leak detection box 100. Both ends of the tested composite pipe 500 are clamped on the pipe clamp 400. The pipe body of the composite pipe 500 is in the water in the leak detection box 100. An air pipe 310 and a pipe joint 320 are provided on the frame 300. The air pipe 310 is connected to the composite pipe 500 through the pipe joint 320, and the air pipe 310 is externally connected to an air pump.

[0032] The pipe clamp 400 of this embodiment includes a conical part 410, an electric push rod 420, a wire seat 430 and a wire rope 440. A mounting plate is provided on the rotating arm 200, and the conical part 410 is installed on the mounting plate. The conical part 410 is hollow and has two ends through. The flat end of the conical part 410 is connected to the pipe joint 320. Electric push rods 420 are provided at both ends of the conical part 410. The electric push rod 420 is provided with a wire seat 430, and the wire rope 440 is installed on the wire seat 430.

[0033] In this embodiment, two steel wire ropes 440 are provided on each steel wire seat 430 , and both ends of the same steel wire rope 440 are connected to the steel wire seat 430 . The steel wire rope 440 passes around the conical member 410 , and a rubber layer is provided at the conical end of the conical member 410 , and the conical end is inserted into the composite pipe 500 .

[0034] The steel wire rope 440 of this embodiment fits the outer wall of the composite pipe 500, and the contact angle between the steel wire rope 440 and the outer wall of the composite pipe 500 is greater than 180°.

[0035] The frame 300 of this embodiment is provided with a rotating motor 330 and a metal chain. The metal chain is wound around the chain shaft. One end of the metal chain is connected to the rotating arm 200. The rotating motor 330 drives the chain shaft to rotate.

[0036] Working principle: The two ends of the composite pipe 500 are clamped by the pipe clamps 400 on the two rotating arms 200, and locked by the wire rope 440. When locked, the electric push rod 420 needs to be tightened to pull the wire rope 440 to tighten and lock the composite pipe 500. Then the rotating arm 200 rotates and descends, so that the entire composite pipe 500 is immersed in water, and the air pump is started to inflate the composite pipe 500. Observe whether there are bubbles in the water in the leak detection box 100, and conduct a leak detection experiment. It should be noted that a pressure gauge can also be installed on the air pipe 310 to observe the air pressure. The whole detection process is simple. Due to the provision of the conical part 410, it can theoretically support composite pipes 500 of larger diameters, and the outer wall of the composite pipe 500 has a large friction due to the weaving of composite materials, so the wire rope 440 can be firmly clamped without slipping.

[0037] It should be noted that the two rotating arms 200 are installed together on a mounting shaft, wherein the rotating arms 200 are locked by locking bolts, and the mutual distance between them can be adjusted by lateral movement by loosening the bolts.

[0038] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
