Description

Technical Field

[0001] The utility model relates to the field of underground pipeline detection instruments and equipment, in particular to a separate underground pipeline detection device. Background Art

[0002] Separate pipeline detectors typically consist of a transmitter and receiver. The detectors are most accurate when detecting within 15 meters of the transmitter. The receiver has a built-in induction coil that picks up the pipeline's magnetic field. The coil generates an induced current, which is then used to calculate the pipeline's direction and path.

[0003] During active detection, the transmitter must be placed within the area to be detected and the receiver must be moved. The receiver must remain vertical during detection. If the approximate location is unknown, two people must work together, each holding a transmitter and a receiver. This requires close coordination, as large errors can easily occur. Furthermore, the height of the receiver from the ground must be adjusted to achieve the most stable state during actual operation. Therefore, during detection, the height of the transmitter from the ground must be kept as stable as possible to ensure accurate detection distance.

DETAILED DESCRIPTION

[0026] In order to make it easier to understand the structure of the present invention and the functional features and advantages that can be achieved, the following

[0027] The preferred embodiment of the utility model is described in detail with reference to the drawings as follows:

[0028] Example:

[0029] like Figures 1 to 8 As shown, the present invention provides a separate underground pipeline detection device, including a transmitter 1 and a receiver 2. The transmitter 1 transmits a specific frequency to the pipeline, and the receiver 2 then detects the reflected frequency. It also includes a transmitter bracket 3 and a receiver bracket 4. The transmitter bracket is used to place the transmitter 1, and the receiver bracket 4 is used to place the receiver 2. The top of the transmitter bracket 3 is fixedly connected to a frame 41 for placing the transmitter 1. The frame 41 is used to place the transmitter 1. The frame 41 is a square frame. A sliding rod 5 is slidably connected to the receiver bracket 4. One end of the sliding rod 5 is fixedly connected to a limiting mechanism 6, and the other end of the sliding rod 5 is movably connected to a snap mechanism 7. The limiting mechanism 6 and the snap mechanism 7 jointly limit and snap the receiver 2. The receiver bracket 4 is fixedly connected to a sliding groove 8 for raising and lowering the limiting mechanism 6 and the snap mechanism 7. The sliding rod 5 slides in the sliding groove 8. The transmitter bracket 3 and the receiver bracket 4 are movably connected via a connecting pipe 101.

[0030] Both the transmitter bracket 3 and the receiver bracket 4 include rollers 31, a frame 32, and a beam 33. The rollers 31 are rotatably connected to the bottom wall of the frame 32, while the beam 33 is fixedly connected to the middle of the frame 32. The frame 32 is a bilaterally symmetrical structure supported by supporting rods on both sides. The frame 32 is trapezoidal in shape, enhancing stability during forward movement. The rollers 31 are located at the four corners of the frame 32.

[0031] As another example, Figure 3 and Figure 4 As shown, the sliding rod 5 of the present application is fixedly connected to the frame 32, and the limiting mechanism 6 includes a first support frame 61, a limiting plate 62, and a supporting plate 63. The first support frame 61 is fixedly connected to one side of the sliding rod 5, the limiting plate 62 is fixedly connected to the first support frame 61, and the supporting plate 63 is fixedly connected to the first support frame 61. The supporting plate 63 is parallel to the sliding rod 5, and the length of the supporting plate 63 is shorter than the length of the sliding rod 5.

[0032] The latch mechanism 7 includes a second support frame 71, a pressing plate 72, and a latch 73. The second support frame 71 is slidably connected to the side of the sliding rod 5 away from the first support frame 61. The pressing plate 72 is fixedly connected to the second support frame 71 and is symmetrical and identical to the limiting plate 62. The latch 73 is movably inserted into the second support frame 71, and the first and second support frames 61 and 71 are fixed together by the latch 73. A rubber sheet is fixedly connected to the corresponding sides of the limiting plate 62 and the pressing plate 72 to reduce damage to the receiver 2. The latch 73 is a threaded latch 73.

[0033] When in use, the handle of the receiver 2 is placed on the supporting plate 63 and slides on the sliding rod 5 to the first support frame 61, pushing the second support frame 71 to slide on the sliding rod 5 until the second support frame 71 and the first support frame 61 press the receiver 2, and then tighten the pin 73 to fix it.

[0034] As another example, Figure 4 and Figure 5 As shown, the sliding grooves 8 of the present application are located at both ends of the sliding rod 5. The sliding grooves 8 are non-through, preventing the sliding rod 5 from sliding out of the sliding grooves 8 during the sliding process, thereby limiting the ends of the sliding rod 5. The side walls of the sliding grooves 8 are provided with a number of equally spaced circular holes 81, and a latch 9 is movably inserted into the circular holes 81. The latch 9 includes a connecting block 91, an insertion rod 92, and a latch 93. The insertion rod 92 is fixedly connected to each end of the connecting block 91. The latch 93 is fixedly connected to the end of the insertion rod 92 away from the connecting block 91. The distance between the two insertion rods 92 is greater than the diameter of the sliding rod 5. The latch 93 is made of rubber and has a frustum shape.

[0035] When in use, slide the sliding rod 5 up and down, and observe the detection value on the receiver 2, stop after a stable distance from the ground, insert the insertion rod 92 into the sliding groove 8, and make the sliding rod 5 located between the two insertion rods 92. Since the block 93 is made of rubber and can pass through the circular hole 81, but it is in the shape of a truncated cone, it can prevent the insertion rod 92 from slipping out of the circular hole 81.

[0036] As another example, Figure 7 and Figure 8As shown, the two corresponding rollers 31 of the present application are connected by a rotating shaft 10. The rotating shaft 10 has a limit slot 11 engraved on its surface and extends beyond the rollers 31. The ends of a connecting tube 101 are movably connected to the corresponding rollers 31 on the transmitter bracket 3 and the receiver bracket 4, respectively. A buckle strip 12 that matches the limit slot 11 is fixedly connected to the inner wall of the connecting tube 101. To ensure a stable connection between the connecting tube 101 and the rotating shaft 10, threaded holes can be pre-set on the connecting tube 101 and the rotating shaft 10. When the connecting tube 101 is connected to the rotating shaft 10, it is fixed with screws. When the transmitter 1 and receiver 2 need to be moved simultaneously, the connecting tube 101 is placed on the rotating shafts 10 of the transmitter bracket 3 and the receiver bracket 4. When one rotating shaft 10 rotates, the other rotating shaft 10 rotates synchronously. The user only needs to push the receiver bracket 4, or another person can assist in pushing the transmitter bracket 3. During this process, the transmitter 1 and receiver 2 move in the same direction and at the same speed, improving the accuracy and stability of detection. When the transmitter 1 does not need to be moved, the connecting pipe 101 is removed and the receiver bracket 4 can be pushed by one person.

[0037] The working principle of the present application is a separate underground pipeline detection device: a transmitter bracket 3 and a receiver bracket 4, the transmitter bracket is used to place the transmitter 1, the receiver bracket 4 is used to place the receiver 2, the top of the transmitter bracket 3 is fixedly connected to a frame 41 for placing the transmitter 1, and the frame 41 is used to place the transmitter 1.

[0038] During use, the handle of receiver 2 is placed on support plate 63 and slid onto sliding rod 5 to the first support bracket 61. Second support bracket 71 is pushed and slid onto sliding rod 5 until second support bracket 71 and first support bracket 61 press receiver 2 together, and then latch 73 is tightened to secure. Sliding rod 5 is then slid up and down, observing the detection value on receiver 2. Stop when a stable distance from the ground is reached. Insert rod 92 into sliding slot 8, positioning sliding rod 5 between the two rods 92. Since block 93 is made of rubber and can pass through circular hole 81, its frustum shape prevents rod 92 from slipping out of circular hole 81. When both transmitter 1 and receiver 2 need to be moved simultaneously, connecting tube 101 is placed over the rotating shafts 10 of transmitter bracket 3 and receiver bracket 4. When one rotating shaft 10 rotates, the other rotates synchronously. The user simply pushes receiver bracket 4, or another person assists in pushing transmitter bracket 3. During this process, transmitter 1 and receiver 2 move in the same direction and at the same speed, improving detection accuracy and stability. When transmitter 1 no longer needs to be moved, connecting tube 101 is removed, and one person can push receiver bracket 4.

Any person skilled in the art can utilize the above technical content to make many possible changes and modifications to the present invention without departing from the scope of the present invention, or modify it into an equivalent embodiment with equivalent changes. Therefore, any changes, modifications, equivalent changes, and modifications made to the above embodiments based on the technology of the present invention that do not depart from the content of the present invention are within the scope of protection of the present invention.
