Description

Probe structure for underground water pipeline detection

Technical Field

The utility model relates to the technical field of underground pipeline detection equipment, in particular to a probe structure for detecting an underground water pipeline.

Background

The underground pipeline is a pipeline laid underground for conveying liquid, gas or loose solid, and is generally laid underground in a city; the method comprises the following steps that the damage detection of the underground pipeline is needed during daily maintenance, so that the overall structure condition of the pipeline is mastered; in the field of gas, because the internal structure of an underground gas pipeline is complex and is buried underground, great difficulty is caused to the detection and maintenance of the pipeline, and at present, leaked escaping gas in the underground pipeline can be detected on the ground through a probe for troubleshooting; however, the existing probes do not generate a vacuum pressure sufficient to draw gas from the subsurface and asphalt or concrete surfaces, resulting in inaccurate test results.

SUMMERY OF THE UTILITY MODEL

In view of the above-mentioned shortcomings of the background art, the present invention provides a probe structure for underground water pipeline detection.

The technical scheme adopted by the utility model is as follows: underground water pipeline detects uses probe structure, and the key lies in: including the body of vertical setting, the body passes through the horizontal arm and is close to lifting sleeve fixed connection, the upper portion of body is connected with the change-over valve, the change-over valve is pipe connection gas detector and vacuum pump respectively, the upper end of body is sealed, the lower extreme of body is connected with buffer container, buffer container's bottom is connected with the sucking disc, buffer container's top and bottom respectively with the body with the sucking disc intercommunication, the cover has the butt ring on the body, centers on the border of sucking disc is equipped with the round clamping ring, the clamping ring with connect through the elastic component between the butt ring. The effect of this scheme is that body, buffer container and sucking disc intercommunication form gas flow channel, and the body pushes down the in-process, and the butt ring exerts decurrent pressure to the elastic component to the clamping ring is under the effect of elastic component, with sucking disc and ground in close contact with, avoids sucking disc and the contact surface of ground airtight contact to appear gas leakage, makes the gas extraction in-process, forms the vacuum of enough low among the gas flow channel, can absorb the gas delivery of revealing of underground pipeline to be used for detecting in the gas detector through ground.

Preferably, the buffer container is a spherical container. The effect of this scheme makes to form flexible connection between body and the sucking disc, avoids exerting pressure the in-process, leads to the contact to damage.

Preferably, the abutment ring is disposed proximate a top of the buffer container. The effect of this solution is that the deformation pressure of the elastic element can be increased.

Preferably, the buffer container and the sucker are both made of rubber.

Preferably, the elastic part is many elastic rods, many the elastic rods surround buffer container evenly sets up, and is adjacent the middle part of elastic rod is connected through the elasticity rope. The effect of this scheme can become to pressure to the sucking disc to increase the contact strength of sucking disc and the airtight contact of ground, avoid this ground department gas leakage, improve the suction gas in-process, the inside vacuum pressure of sucking disc.

Has the advantages that: compared with the prior art, the probe structure for detecting the underground water pipeline provided by the utility model has the advantages that the pressure is applied to the pipeline body by a user, so that the edge of the sucking disc is tightly contacted with the ground under the action of the elastic piece by the pressing ring, the gas leakage of the contact surface of the sucking disc, which is in airtight contact with the ground, is avoided, the low enough vacuum is formed between the sucking disc and the ground, and the vacuum pump is strong enough to pump gas through the ground.

Detailed Description

In order to make the technical solutions of the present invention better understood, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Example 1

As shown in fig. 1-2, the probe structure for underground water pipeline detection comprises a vertically arranged pipe body 1, the upper part of the tube body 1 is connected with a conversion valve 2, the conversion valve 2 is respectively connected with a gas detector 9 and a vacuum pump 8 through pipelines, the upper end of the pipe body 1 is closed, the lower end of the pipe body 1 is connected with a buffer container 3, the buffer container 3 is a spherical container, the bottom of the buffer container 3 is connected with a sucker 4, the buffer container 3 and the sucker 4 are both made of rubber materials, the top and the bottom of the buffer container 3 are respectively communicated with the tube body 1 and the sucker 4, the tube body 1 is fixedly sleeved with a butting ring 5, the abutting ring 5 is arranged close to the top of the buffer container 3, a circle of pressing ring 6 is arranged around the edge of the sucker 4, and the pressing ring 6 is connected with the abutting ring 5 through an elastic piece 7; the elastic part 7 is a plurality of elastic rods, the elastic rods 71 surround the buffer container 3 and are evenly arranged, and the middle parts of the adjacent elastic rods 71 are connected through elastic ropes 72.

The working principle is as follows: the user is through applying decurrent pressure to the body, pastes tightly to sucking disc and ground, and change over valve is adjusted, closes the gas passage of gas detector and body, starts the vacuum pump, takes out sucking disc and ground cover position to vacuum, and change over valve is adjusted, opens the gas passage of gas detector and body, and gas detector detects the condition whether to take place to leak gas.

Finally, it should be noted that the above-mentioned description is only a preferred embodiment of the present invention, and those skilled in the art can make various similar representations without departing from the spirit and scope of the present invention.
