TECHNICAL FIELD

[0001] The utility model relates to high frequency pipeline internal detection technical field, concretely to a kind of high frequency pipeline internal pressure wave injection device. BACKGROUND

[0002] High frequency pipeline internal pressure wave injection is a technical means for detecting internal defects and problems of pipeline. Its principle is based on the characteristics of pressure wave propagation in pipeline. High frequency pipeline internal pressure wave injection can also be used to detect the sealing performance of the connecting parts, valves, elbows and other parts of the pipeline, as well as the resistance and flow rate and other parameters in the pipeline system. By precisely analyzing the propagation and reflection of the pulse wave, detailed information of the pipeline system can be obtained, providing important reference for the maintenance and management of the pipeline.

[0003] For example, the authorized announcement number "CN109780447A" is named a method for detecting the blockage condition in the pressure pipeline using pulse pressure wave. The fast opening and closing electromagnetic valve actively emits a pulse pressure wave in the pipeline. The effective information in the incident wave and the reflected wave is analyzed, which can accurately determine the number and type of blocked sections, and can obtain the blocked position, blocked rate and blocked length. It is simple to operate and has high precision. At present, high frequency pipeline internal pressure wave injection needs to use high frequency pipeline internal pressure wave injection device to realize. The inside of the conventional pressure wave injection device is provided with a plurality of pipes for conveying pressure wave. The pipe is a hose, which is generally inserted into the high frequency pipeline internal pressure wave injection device for storage by bending a few times. Therefore, the pipe will be in a zigzag state for a long time, which not only makes storage and collection more troublesome, but also easily causes cracks at the folded part of the pipe, affecting the service life of high frequency pipeline internal pressure wave injection.

[0004] At the same time, the existing high frequency pipeline internal pressure wave injection device adopts a common box body design. The bottom surface of the box body is flat and convenient to place. However, because there are many internal structure devices, the weight of the box body with high frequency pipeline internal pressure wave injection device will be very heavy. In actual use, the operator is difficult to carry and needs to borrow force, which makes the operation more troublesome and affects the use effect of high frequency pipeline internal pressure wave injection.
