Description

Technical Field

[0001] The utility model relates to a detector, in particular to an underground pipeline detector. Background Art

[0002] The pipeline detector can quickly and accurately detect the location, direction, depth and location and size of the damaged points of the anti-corrosion layer of underground water pipes, metal pipes, cables, etc. without damaging the ground cover. It is one of the necessary instruments for water companies, gas companies, railway communications, municipal construction, industrial and mining, and infrastructure units to renovate, repair, and survey underground pipelines.

[0003] The pipeline detector is generally composed of two parts: a transmitter and a receiver. The transmitter applies a signal current of a special frequency to the pipeline under test, and generally adopts three excitation modes: direct connection method, induction method and clamp method. The receiver has a built-in induction coil to receive the magnetic field signal of the pipeline. The coil generates an induced current, thereby calculating the direction and path of the pipeline. The specific operation method is that the transmitter is electrically connected to the pipeline under test and grounded. The inspector turns on the receiver and holds the device, swings his arm slightly to make the receiver swing back and forth, and walks forward. When the receiver detects fluctuations, the pipeline under test is buried under the corresponding surface. When the depth of the pipeline needs to be detected, the receiver needs to be placed vertically to ensure the accuracy of the detection value. This series of operations requires manual handheld equipment to be performed. Therefore, when there are too many detection tasks, the physical exertion of the inspector is also greater. Summary of the invention

[0004] The utility model provides an underground pipeline detector, which solves the problem in the prior art that long-term handheld receiver detection will lead to excessive physical consumption of personnel.

[0005] The above-mentioned technical problems of the utility model are mainly solved by the following technical solutions: an underground pipeline detector, including a transmitter and a receiver, characterized in that: the receiver includes a mobile platform, a roller arranged on the mobile platform, a joystick rotatably arranged on the mobile platform, a swing frame rotatably arranged on the mobile platform, an operation panel and a receiving module arranged on the swing frame; a transmission assembly is connected between the joystick and the swing frame, so that the joystick can synchronously drive the swing frame to turn through axial rotation; a horizontal stabilization platform is provided on the swing frame, and the receiving module is arranged on the horizontal stabilization platform.

[0006] The operation mode of the utility model is: the transmitter is electrically connected to the pipeline to be tested and grounded. After the detection personnel make corresponding settings on the receiving module through the operation panel, they can push the mobile platform to roll by holding the joystick. At the same time, by continuously turning the joystick forward and backward, the swing frame can be driven to swing left and right through the transmission component, so that the receiving module can swing left and right within a certain range. When the utility model is in a static state, the horizontal stabilization platform can autonomously correct the posture of the receiving module to a vertical downward state, so as to facilitate accurate data when detecting the depth of the pipeline.

[0007] Therefore, compared with the prior art, the utility model has the following characteristics: 1. The utility model can be operated with one hand, and the operation process is relatively labor-saving, and it has an automatic posture adjustment function, which can greatly reduce the workload of detection personnel, improve detection efficiency, and improve detection accuracy.
