Description

Technical Field

[0001] The utility model belongs to the field of pipeline leakage detection, and particularly relates to a leakage detection sensing device for underground water supply pipelines. Background Art

[0002] Electromagnetic wave detection and acoustic wave detection are traditional means for detecting underground pipeline leakage. By utilizing the propagation characteristics of electromagnetic waves or acoustic waves in the medium, non-excavation detection of underground pipelines is carried out. These technologies can penetrate soil and coverings to form two-dimensional or three-dimensional images of the pipeline and its surrounding environment, helping detection personnel identify the pipeline position, orientation, burial depth, and potential leakage areas. However, it is difficult to detect problems when the underground water supply pipeline leaks slowly by the above means, the detection response speed is relatively slow, and the detection cost is relatively high.

[0003] The main technical problem to be solved by the utility model is that the existing leakage detection devices have low detection accuracy and are easily affected by external interference, resulting in false alarms or missed alarms. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a leakage detection sensing device for underground water supply pipelines. Due to the electric push rod driving the piston and the seal to reciprocate up and down inside the opening, the utility model is more sensitive to leakage detection and has a faster detection response speed.

[0008] Preferably, an opening is formed at the top of the reaction ring, a fixing plate is connected to the inner wall of the opening, an electric push rod is connected to the top of the fixing plate, a piston is connected to the top of the electric push rod, a seal is connected to the top of the piston, and the electric push rod is used to drive the seal to reciprocate up and down inside the opening.

[0009] Preferably, the support assembly includes two groups of support blocks, two groups of side plates are connected to the inner sides of the two groups of support blocks, and two groups of support plates are connected to the bottoms of the support blocks.

[0010] Preferably, the pipeline assembly includes a pipe body placed on the top of the support block, and two groups of connecting rings are connected to the outer side of the pipe body.

[0011] Preferably, the sealing assembly includes a sealing chamber connected to the surface of the pipe body. Two groups of operation plates are connected to the surface of the sealing chamber, and a sensor for alarming is connected to the bottom of the water absorption ring.

[0012] Preferably, both the front and rear sides of the piston are semi-circular. The sealing member is located inside the opening, and the sealing member abuts against the inside of the opening.

[0013] The utility model can achieve the following beneficial effects:

[0014] In the utility model, since the electric push rod drives the piston and the sealing member to reciprocate up and down inside the opening, the leakage detection is more sensitive and the detection reaction speed is faster.

[0015] By arranging the sealing assembly and the reaction assembly, the utility model can monitor the water seepage condition in the pipeline in real time, and send out an alarm signal in time through the sensor, ensuring that the leakage problem can be quickly discovered and processed.

[0016] In the utility model, the electric push rod drives the piston and the sealing member to reciprocate up and down inside the opening, and uses air pressure to accelerate the adsorption of seepage water, improving the sensitivity and accuracy of detection and reducing the possibility of false alarms and missed alarms.

Inside the support assembly 1, a pipeline assembly 2 is placed. A sealing assembly 3 is fixedly connected to the surface of the pipeline assembly 2, and a reaction assembly 4 is fixedly connected to the bottom of the sealing assembly 3.

[0025] The reaction assembly 4 includes a through pipe 401 fixedly connected to the bottom of the sealing assembly 3. A reaction ring 402 is fixedly connected to the bottom of the through pipe 401. An opening 403 is formed at the top of the reaction ring 402, facilitating the seepage water in the sealing assembly 3 to flow into the inside of the opening 403 through the through pipe 401. A fixing plate 404 is fixedly connected to the inner wall of the opening 403. An electric push rod 405 is fixedly connected to the top of the fixing plate 404. A piston 406 is fixedly connected to the top of the electric push rod 405. A seal 407 is fixedly connected to the top of the piston 406, facilitating starting the electric push rod 405 to drive the piston 406 and the seal 407 to reciprocate up and down inside the opening 403. A water absorption ring 408 is fixedly connected to the bottom of the reaction ring 402.

[0026] The support assembly 1 includes two support blocks 101. Two side plates 102 are fixedly connected to the inner sides of the two support blocks 101. Two support plates 103 are fixedly connected to the bottoms of the support blocks 101. The pipeline assembly 2 includes a pipe body 201 placed on the top of the support blocks 101. Two connecting rings 202 are fixedly connected to the outer side of the pipe body 201, facilitating the connection of the pipe body 201 through the connecting rings 202.

[0027] The sealing assembly 3 includes a sealing chamber 301 fixedly connected to the surface of the pipe body 201. Two operation plates 302 are fixedly connected to the surface of the sealing chamber 301. A sensor 5 for alarming is fixedly connected to the bottom of the water absorption ring 408.

[0029] Working principle:

[0030] The through pipe 401 is communicated with the sealing chamber 301. When detecting the pipe body 201, the staff starts the electric push rod 405 to drive the piston 406 and the seal 407 to reciprocate up and down inside the opening 403. When the pipe body 201 leaks, the leaked water flows into the sealing chamber 301. Due to the extrusion of the seal 407 in the opening 403, the water in the sealing chamber 301 is adsorbed by air pressure acceleration through the through pipe 401. The adsorbed water is then adsorbed into the water absorption ring 408 through the opening 403 at the top of the reaction ring 402. When the sensor 5 senses the water in the water absorption ring 408, it gives a reminder.
