Description

Technical Field

[0001] The utility model belongs to the technical field of underground pipeline detection, in particular to a novel underground pipeline detection device. Background Art

[0002] The detection of buried steel pipelines requires the use of a ground rod inserted into the ground for detection. The ground rod receives the induced current on the surface of the metal pipeline and transmits it to the receiver for further processing. In order to enable the ground rod to accurately sense the current, it is necessary to insert the ground rod as deep as possible into the ground. When inserting the ground rod, the handle is generally pressed and rotated to make it insert deeper into the ground. Since it needs to be rotated, the operation is inconvenient, and it cannot be rotated in a small space, which affects the insertion effect. Therefore, we have designed a buried pipeline detection device that is easy to insert into the ground. Utility Model Content

[0015] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0016] A new type of buried pipeline detection device, such as Figure 1As shown, it includes a ground needle body 1, a handle 2 is provided on the ground needle body 1, a barrier piece 9 is fixedly installed on the ground needle body 1, the barrier piece 9 is annular, and the inner periphery of the barrier piece 9 is fixedly connected to the outer periphery of the ground needle body 1, and a connecting point 10 is provided on the barrier piece 9, and the connecting point 10 is used to connect with the instrument during work. It is a prior art. A threaded groove 3 is provided on the ground needle body 1, and a vertical pipe 4 is fixedly installed on the handle 2. The ground needle body 1 is rotatably connected to the insertion rod 5 through a one-way bearing 8. The upper end of the ground needle body 1 is fixedly connected to the inner ring of the one-way bearing 8, and the outer ring of the one-way bearing 8 is fixedly connected to the lower end of the insertion rod 5. The insertion rod 5 is coaxially arranged with the ground needle body 1, and the vertical pipe 4 is slidably connected to the insertion rod 5. The insertion rod 5 is cylindrical and coaxially arranged with the vertical pipe 4. A spiral groove 6 is provided on the insertion rod 5, and a slider 7 is slidably installed in the spiral groove 6. The slider 7 is fixedly installed on the inner wall of the vertical pipe 4. The utility model has a simple structure and an ingenious design. By pressing the handle 2 to drive the vertical tube 4 to move, the underground needle body 1 can be driven to rotate, which can better insert it into the ground. Moreover, through the cooperation of the one-way bearing 8, the underground needle body 1 will not reset when the vertical tube 4 moves upward, which is convenient to use, can meet actual needs, and is suitable for promotion. When using the utility model, first insert the bottom of the underground needle body 1 into the target soil, and then press the handle 2 downward. The handle 2 drives the vertical tube 4 and the slider 7 to move downward. The slider 7 gives a thrust to the inner wall of the spiral slide 6, thereby driving the insertion rod 5 to rotate. The rotation of the insertion rod 5 drives the underground needle body 1 to rotate together through the one-way bearing 8, thereby moving the underground needle body 1 into the ground. The underground needle body 1 is provided with a threaded groove 3 to make it easy to screw into the ground. When the slider 7 slides to the bottom end of the spiral slide 6, it moves upward. Pull the handle 2 to reset the vertical pipe 4. At the same time, the insertion rod 5 rotates in the opposite direction. At this time, due to the action of the one-way bearing 8, the insertion rod 5 and the underground needle body 1 rotate relative to each other, and the underground needle body 1 will not be driven by the insertion rod 5 to rotate in the opposite direction. When the slider 7 slides to the top of the spiral slide groove 6, press the handle 2 downward again. Repeat this operation until the ground contacts the barrier piece 9. The installation of this device is completed, and then connect the connecting point 10 to the instrument for use. After the detection is completed, the underground needle body 1 can be pulled out of the ground through the handle 2.

[0017] Specifically, as shown in the figure, a spring 20 is installed within the riser 4 of this embodiment, connecting the insertion rod 5 and the handle 2 via the spring 20. One end of the spring 20 is fixedly connected to the insertion rod 5, and the other end of the spring 20 is fixedly connected to the handle 2. When the handle is pressed to move the riser 4 downward, the spring 20 is compressed. When it is necessary to return the riser 4 to its original position, the handle 2 is no longer pressed, and the riser 4 automatically returns to its original position under the action of the spring 20.

[0018] Specifically, as shown in the figure, a coaxial guide rod 30 is fixedly mounted on the insertion rod 5 of this embodiment. A through hole 31 is formed on the handle 2 corresponding to the guide rod 30. The guide rod 30 is slidably connected to the through hole 31, and the spring 20 is sleeved on the guide rod 30. When the vertical tube 4 rotates and slides on the insertion rod 5, the guide rod 30 slides within the through hole 31, guiding the vertical tube 4 and making the vertical tube 4 more stable during movement. At the same time, the guide rod 30 can keep the spring 20 in a vertical state, preventing it from bending due to compression, and ensuring the normal use of the spring 20.

[0019] Furthermore, as shown in the figure, a nut 40 is fixedly mounted on the barrier plate 9 of this embodiment. One side of the nut 40 is fixedly connected to a connecting rod, which is fixedly mounted on the barrier plate 9. The internal thread of the nut 40 cooperates with a first bolt 41 for mounting. A first slot 42 is defined on the insertion rod 5, and the first bolt 41 can be inserted into the first slot 42. When the first stud 41 is screwed so that one end thereof is inserted into the first slot 42, the insertion rod 5 and the burrowing needle body 1 are completely unable to rotate relative to each other. When the insertion rod 5 rotates in the opposite direction, the burrowing needle body 1 can be driven in the opposite direction, thereby facilitating the removal of the burrowing needle body 1 from the ground for easier use.

[0020] Furthermore, as shown in the figure, the insertion rod 5 of this embodiment is provided with a second slot 50, and the vertical tube 4 is provided with a threaded hole and threadedly mounted with a second bolt 51, which can be inserted into the second slot 50. The vertical tube 4 is moved downward until the second bolt 51 is aligned with the second slot 50, and the second bolt 51 is screwed into the second slot 50. At this time, the vertical tube 4 and the insertion rod 5 cannot rotate or slide relative to each other, thereby forming a self-locking function, which facilitates the direct insertion and removal of the ground needle body 1 from the ground, and is convenient for use.

[0021] Furthermore, as shown in the figure, the handle 2 of this embodiment is provided with anti-skid patterns, which are not shown in the figure. The anti-skid patterns can increase the friction when holding the handle, making it easier to use.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
