Description

Technical Field

[0001] The utility model relates to the field of pipeline detection, in particular to a pipeline detector. Background Art

[0002] A pipeline detector is a professional tool used to detect the location and buried depth of underground pipelines. It uses different technical principles to detect underground pipelines, such as water pipes, gas pipes, cables, etc. Pipeline detectors are generally divided into two categories: electromagnetic detection and underground pipeline radar. Pipeline detectors are very important in urban construction, road construction, land development and other activities. They help workers avoid damaging existing underground pipelines and ensure the safety and efficiency of construction.

[0003] In the application number CN202121877058.6, a "pipeline detector" is disclosed. This application solves the problem that during the use of existing pipeline detectors, the pipeline wiring in some areas is dense, which requires testers to hold the detector for a long time, easily causing fatigue to the testers and thus reducing work efficiency. However, the pipeline detector in this application is not equipped with a relevant detection area marking mechanism. In practice, after detection, the lack of intuitive markings will make it difficult for construction workers to determine whether the pipeline detection has been completed in the area, which will result in repeated detection of pipelines in the same area. Repeated detection of the same area will waste time and human resources and increase project costs. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a pipeline detector, which solves the problem that the current pipeline detector cannot mark the detection area, resulting in repeated detection.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions: a pipeline detector, including a detection frame, a detection area marking mechanism is arranged in the middle of the upper surface of the detection frame, the detection area marking mechanism includes a detection frame, a prompt, an extrusion airbag, a pushing arm, a connecting pipe, a micropore and a sealing plug, the detection frame is fixedly connected to the detection frame, a plurality of prompt tubes are fixedly connected to the left and right sides of the upper surface of the detection frame, and two adjacent prompt tubes are equidistantly distributed on the upper surface of the detection frame, solid gouache pigment powder is arranged inside the plurality of prompt tubes, a connecting pipe is fixedly connected to the lower surface of the prompt tube, micropores are arranged at the lower end of the connecting tube, an extrusion airbag is arranged on one side of the connecting tube, the extrusion airbag and the connecting pipe are interconnected, the extrusion airbag is fixedly connected to the inside of the detection frame and the front side is arranged through the inside of the detection frame.

[0006] Preferably, a mobile detection mechanism is arranged above the detection frame, and the mobile detection mechanism includes a fixed bracket, an L-shaped support plate, a rotating screw, a threaded ring and a limiting slider. The outer sides of the front and rear ends of the fixed bracket are fixedly connected with L-shaped support plates, and the end of the L-shaped support plate away from the fixed bracket is fixedly connected to the upper surface of the detection frame.

[0007] Preferably, connection plates are fixedly connected to the front and rear sides of the lower surface of the fixed bracket, and a rotating screw is rotatably connected between the front and rear connection plates.

[0008] Preferably, the outer side of the rotating screw is threadedly connected to two threaded rings, the upper ends of the two threaded rings are fixedly connected to the front and rear sides of the lower surface of the limiting slider, and the upper end of the limiting slider is slidably connected to the lower surface of the fixed bracket.

[0009] Preferably, the lower ends of the two threaded rings are fixedly connected to a connecting rod, and one end of the connecting rod away from the threaded ring is fixedly connected to the upper surface of the detector body.

[0010] Preferably, a motor is provided on the outer side of the rear connecting plate, and the output end of the motor is transmission-connected to the rotating screw.

[0011] Preferably, four corners of the lower surface of the detector body are fixedly connected with pushing arms.

[0013] Preferably, a detection receiver is fixedly connected to the front end of the detection frame.

[0014] Preferably, the detection receiver is electrically connected to the detector body.

[0015] Beneficial Effects

[0016] The utility model provides a pipeline detector. Compared with the prior art, it has the following beneficial effects:

[0017] 1. In the utility model, through the detection area marking mechanism, in the process of mobile detection of underground pipelines by the mobile detection mechanism, as the detector body moves forward, the pushing arm on the lower surface of the detector body will squeeze the squeezing airbag on the inner side of the detection frame. After the squeezing airbag is squeezed, the squeezing airbag injects airflow into the connecting pipe. Under the action of the airflow, the solid gouache pigment powder accumulated in the connecting pipe can be discharged to the ground through the micropores at the lower end thereof. After that, as the detector body completely moves to the front side, multiple squeezing airbags can be squeezed by the pushing arm, thereby leaving two rows of dot marks on the ground. Subsequent detection personnel can judge whether the pipeline detection has been completed in the current area by observing the dot marks left, thereby avoiding repeated pipeline detection in the area.

[0018] 2. In the utility model, by setting up a mobile detection mechanism, before pipeline detection, the device is pushed to the ground area where pipeline detection is required, and the rotation of the rotating screw is controlled by a motor. After the rotating screw rotates, the two threaded rings connected by the outer thread of the rotating screw can drive the detector body to move. After the movement, the detector body can detect pipelines in different areas, thereby reducing the workload of the detection personnel due to the mobile device detecting pipelines in different areas.

It should be noted that when the extrusion airbag 403 is not squeezed, due to the small diameter of the micropore 406, the solid gouache pigment powder will not be discharged from the micropore 406. An extrusion airbag 403 is arranged on one side of the connecting tube 405. The extrusion airbag 403 and the connecting tube 405 are interconnected. The extrusion airbag 403 is fixedly connected to the inside of the detection frame 401 and the front side is penetrated and arranged on the inside of the detection frame 401. The four corners of the lower surface of the detector body 2 are fixedly connected with pushing arms 404. The upper end of the prompt tube 402 is threadedly connected with a sealing plug 407. If the solid gouache pigment powder in the prompt tube 402 is insufficient, the sealing plug 407 can be unscrewed and solid gouache pigment powder can be poured into it.

[0030] During operation, before pipeline detection, the device is pushed to the ground area where pipeline detection is required. In the process of moving the detector body 2 to detect the underground pipeline through the mobile detection mechanism 3, as the detector body 2 moves forward, the specific moving method of the detector body 2 is shown in the relevant content of Example 2. The pushing arm 404 on the lower surface of the detector body 2 will squeeze the squeezing airbag 403 on the inner side of the detection frame 401. The squeezing method is push squeezing. After the squeezing airbag 403 is squeezed, the squeezing airbag 403 injects airflow into the connecting pipe 405. Under the action of the airflow, the solid gouache pigment powder accumulated in the connecting pipe 405 can be discharged to the ground through the micropores 406 at the lower end thereof. After that, as the detector body 2 is completely moved to the front side, multiple squeezing airbags 403 can be squeezed by the pushing arm 404, thereby leaving two rows of dot marks on the ground. Subsequent detection personnel can judge whether the pipeline detection has been completed in the current area by observing the dot marks left, thereby avoiding repeated pipeline detection in this area.

The detector body 2 includes a signal transmitter for sending electromagnetic waves or sound wave signals. These signals will pass through the ground. When they encounter pipelines of different materials, part of the signals will be reflected back and the signals reflected back from the underground pipeline will be received by the detection receiver 5. The detection receiver 5 can measure the time it takes for the signal to go back and forth to the pipeline, thereby determining the depth and distance of the pipeline. It should be noted that the specific method for pipeline detection refers to the existing technology, and the specific model of the detection receiver 5 is Garret PD6500i, the detection frame 1 can be equipped with a battery assembly, which is not shown in the figure.
