Description

Technical Field

[0001] This utility model relates to the field of positioning and detection devices, and in particular to a gas pipeline location detection device. Background Technology

[0002] Gas pipeline acoustic positioning equipment typically works by applying a specific frequency vibration signal inside the pipeline, causing the signal to travel along the pipeline and radiate to the ground. A ground-based acoustic probe is then used to collect the signal to locate and confirm the pipeline's direction. Such equipment generally consists of a transmitting unit and a receiving unit, with the receiving end typically equipped with an acoustic probe to sense ground vibration signals.

[0003] Existing acoustic locators for gas pipelines mostly employ fixed-structure pickup probes, whose bottom support design is typically suitable for single ground conditions, such as hard surfaces or soft soil layers. In actual operation, the probe needs to select different contact methods depending on the ground material, such as using it flat on hard ground or inserting it into soft soil. However, existing probes often cannot handle both situations simultaneously, are inconvenient to switch between structures, and have numerous installation or disassembly components, requiring on-site replacement of different probe assemblies to adapt to different ground conditions.

[0004] Existing microphone probe structures require probe replacement or complex adjustments to adapt to different ground types, resulting in low operational efficiency, heavy carrying burden, poor operational continuity, and inability to quickly and stably insert the probe in soft soil conditions, while the probe is unstable on hard ground conditions, affecting signal acquisition quality. Therefore, a microphone probe structure that can quickly switch between hard and soft soil without replacing parts is needed to adapt to different ground environments, thereby improving positioning stability and field operation efficiency. Utility Model Content

[0005] This invention provides a gas pipeline location detection device that can solve the problem in the prior art that the sound pickup probe cannot quickly switch between hard ground and soft soil and requires component replacement to adapt to different ground environments.

[0016] Beneficial effects: The core improvement of this utility model lies in the clamping mechanism formed by the cooperation of a fixed ring 1, a fixed ring 2, a driving block, a telescopic plate, and rollers in the chuck structure. By rotating the screw, the three rollers can be made to clamp the probe 2 towards the center simultaneously, realizing the rapid fixing or release of the probe 2.

[0021] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0022] like Figures 1 to 4 As shown in the figure, a gas pipeline location detection device provided in this embodiment of the present invention includes a transmitter 200, a receiver 100 provided with the transmitter 200, and a chuck structure 300 provided on the receiver 100.

[0023] The receiver 100 includes a probe 101, which in turn includes a handle 104. The handle 104 has anti-slip textures 105 to improve grip stability and prevent slippage during operation. A connecting cable 102 is electrically connected to the upper part of the handle 104, and the other end of the connecting cable 102 is electrically connected to a listening receiver 103. A triangular disk 106 is fixedly connected to the lower end of the handle 104, and probes 107 are fixedly connected to the three corners of the lower surface of the triangular disk 106, forming a stable three-point support structure.

[0024] The chuck structure 300 includes a first fixing ring 301, which is slidably connected to the triangular disk 106. Connecting blocks 312 are evenly distributed and fixed along the circumferential direction on the first fixing ring 301. A second fixing ring 302 is fixedly connected to the lower end of each connecting block 312. The first fixing ring 301 and the second fixing ring 302 are coaxially arranged. Three fixing rods 313 are fixedly connected between the first fixing ring 301 and the second fixing ring 302. A driving block 303 is hinged to each fixing rod 313. A fixing pin 305 is fixedly connected to each of the three corners of the lower surface of the triangular disk 106. A telescopic plate 304 is hinged to each fixing pin 305. The other end of the telescopic plate 304 extends through and slidably connects to the driving block 303, converting the rotational motion of the driving block 303 into the oscillation of the telescopic plate 304. The telescopic plate 304 is located inside the first fixed ring 301 and the second fixed ring 302, with one end hinged to a horizontally arranged roller 306. A probe 108 abuts between the three rollers 306, and the three rollers 306 can simultaneously clamp the probe 108 towards the center, securing it firmly. A fixing pin 307 is fixedly connected to the lower end face of the triangular disk 106, and a support seat 308 is hinged to the fixing pin 307. A fixing pin 309 is fixedly connected to the lower bottom face of the second fixed ring 302, and a nut seat 310 is hinged to the fixing pin 309. A screw 311 is threaded into the nut seat 310, and the other end of the screw 311 is rotatably connected to the support seat 308. Rotating the screw 311 drives the entire mechanism to synchronously achieve the clamping action, resulting in a simple and reliable structure.

[0025] Working Principle: A quick-switchable support and locking mechanism solves the problem of the pickup probe 101's inability to adapt quickly to hard surfaces and soft soil. The probe 101 has two working modes to adapt to different ground conditions. In hard surface mode, the operator holds the handle 104 and places the device on the ground. The probe 107, fixed to the three corners of the bottom surface of the triangular disk 106, acts as a support foot, making stable contact with the ground and forming a stable triangular support platform. This ensures that the probe 101 will not wobble on the hard ground, and the sound wave vibrations from the ground are transmitted to the receiver 103 through the probe 107 and the triangular disk 106 structure. In soft soil mode, the operator drives the chuck structure 300 to lock the probe 108, pressing the device down to allow the slender probe 108 to penetrate the soil, maintaining vertical stability and preventing swaying in soft soil. In this mode, the sound wave vibrations are directly transmitted to the probe 108 embedded in the soil, resulting in a clearer signal.

[0026] To fix probe 2 108, the operator only needs to rotate screw 311 clockwise. Since the other end of screw 311 is threadedly connected to nut seat 310 fixed on fixing ring 2 302, nut seat 310 will drive fixing ring 1 301, fixing ring 2 302 and drive block 303 fixedly connected therebetween to rotate. After drive block 303 rotates, it will drive telescopic plate 304 to retract in the inward direction. At this time, roller 306 will press probe 2 108, thus completing the fixation.

[0027] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
