Description

Technical Field

[0001] This invention relates to the field of underground pipeline network inspection technology, and in particular to an inspection line lead-out device for underground pipeline networks. Background Technology

[0002] In recent years, due to their ease of construction, low pollution of transported materials, and low project cost, plastic pipes have been widely used in underground pipeline construction in China, especially in pipelines transporting gas and tap water. However, because plastic pipes are non-conductive, non-magnetic, and have lower strength than metal pipes, detection cables are often buried along with the pipes during installation for inspection and protection. The electromagnetic field generated by the conductivity of these cables is used to detect the pipe's location. However, since these cables remain buried, how to bring them up from underground to the surface to apply electrical signals for detection is a technical challenge.

[0003] Meanwhile, if plastic pipes are not used as the transport medium, metal pipes are generally used. When metal pipes are buried underground, sacrificial anodes must be used to reduce electrolytic corrosion. Sacrificial anodes also require several cables to be led out from underground from the buried pipeline network.

[0004] In existing technologies, underground detection lines and sacrificial anode lines are connected to terminals. During testing, tools are needed to open the cover, and the terminals of the testing instrument are inserted to connect to the terminals for testing. After testing, the cover is reinstalled. In road use environments, the operation steps are relatively complicated, which affects the testing efficiency.

[0005] Therefore, it is necessary to provide a detection line lead-out device for underground pipe networks to solve the above-mentioned technical problems. Summary of the Invention

Terminal posts are fixedly connected to the upper surface of the lifting plate, and wiring holes are formed next to the terminal posts on the surface of the lifting plate. Protrusions are symmetrically fixedly connected to the surface of the top cover, and these protrusions are slidably inserted into the installation grooves. Vertical grooves are symmetrically formed on the surface of the protrusions, and these vertical grooves are fitted with the limiting blocks and communicate with the grooves.

[0007] Preferably, the adjusting device includes a second spring, a cylinder, an adjusting block, a fixed block, a transverse groove, a third spring, a movable block, a movable column, a top block, and a positioning column.

The cylinder is slidably connected to the protrusion. The end of the cylinder away from the adjusting block is fixedly connected to the fixed block. The surface of the fixed block has a transverse groove. Movable blocks are symmetrically slidably connected to the surface of the transverse groove. The third spring is fixedly connected between the two movable blocks. Movable columns are fixedly connected to the surfaces of the two movable blocks away from the third spring. Both movable columns are slidably connected to the fixed block. The end of the movable column away from the movable block is fixedly connected to the top block. Both top blocks are slidably installed in the mounting groove. The top blocks are fitted with the limiting block. The positioning column is fixedly connected to the bottom of the fixed block. Both positioning columns are slidably inserted into the base.

[0008] Preferably, the second spring is initially in a compressed state.

[0009] Preferably, the surface of the top block is provided with a first inclined groove and a second inclined groove, the surface of the lifting block is provided with a third inclined groove and a fourth inclined groove, and the surface of the limiting block is provided with a fifth inclined groove.

[0010] Preferably, the limiting device includes a fourth spring, a circular block, an inclined block, and limiting posts. The fourth spring is fixedly connected to one end of the surface of the column groove, and the circular block is fixedly connected to the other end of the fourth spring.

[0014] Compared with the prior art, the present invention provides a detection line lead-out device for underground pipeline networks, which has the following beneficial effects:

[0015] 1. In the process of opening the top cover, the fixing block can contact the surface of the inclined block, so that the limiting post and the lifting plate are separated. Under the action of the first spring force, the lifting plate drives the terminal post to extend out of the base, which facilitates connection testing. After the test is completed, simply place the lifting plate under the limiting post, and the top cover and the base are installed together. The vertical groove on the surface of the protrusion cooperates with the limiting block to restore the initial state. This simplifies the operation process, allows the terminal post to extend out of the base, and improves the overall testing efficiency.

[0016] 2. This invention only requires the protrusion to cooperate with the mounting groove. The elastic force of the third spring makes the top block and the surface of the mounting groove in close contact. The top block cooperates with the limiting block to limit the installation of the top cover and ensure stable installation. Attached Figure Description

The upper surface of the lifting plate 10 is fixedly connected to a terminal post 11. The surface of the lifting plate 10 is provided with a wiring hole 12 next to the terminal post 11. The surface of the top cover 2 is symmetrically fixedly connected to a protrusion 13. The protrusion 13 is slidably inserted into the mounting groove 4. The surface of the protrusion 13 is symmetrically opened with a vertical groove 14. The vertical groove 14 is installed in cooperation with the limit block 7. The vertical groove 14 is connected to the groove 3.

[0028] It should be noted that the terminals of the testing instrument are connected to the terminal 11 for testing. After the test is completed, the upper cover 2 is moved from top to bottom, with the protrusion 13 engaging with the mounting groove 4 and the vertical groove 14 engaging with the limiting block 7 for limiting.

By adjusting the position of the adjusting block 17, the top block 23 is driven to cooperate with the lifting block 6, thereby facilitating the installation and disassembly of the upper cover 2 and the base 1.

[0030] The second spring 15 is initially compressed, ensuring sufficient force so that the top block 23 can contact the surface of the limiting block 7 to limit the installation of the top cover 2.

[0034] One corner of the surface of the fixed block 18 is chamfered. During the descent, the fixed block 18 can contact the surface of the inclined block 31 and slide relative to it, thereby driving the circular block 30 and the limiting post 32 to move.

[0035] The upper surface of the cover 2 has symmetrically arranged round holes 33. First, press the adjustment block 17, and then use a hook-like object with one end bent to pass through the round hole 33 to hook up the cover 2 to complete the disassembly of the cover 2.

[0036] Example 2

[0037] A detection line lead-out device for an underground pipeline network includes a base 1, a top cover 2, and a groove 3. The top cover 2 is installed on the top of the base 1. Grooves 3 are symmetrically formed on the surface of the top cover 2. Mounting grooves 4 are symmetrically formed on the surface of the base 1. Sliding grooves 5 are symmetrically formed on the surface of the mounting grooves 4. Lifting blocks 6 are slidably connected to the surface of the sliding grooves 5. Adjustment devices are provided above the two lifting blocks 6. The grooves 3 are slidably installed with the adjustment devices. Limiting blocks 7 are fixedly connected above the lifting blocks 6 on the surface of the mounting grooves 4. Both limiting blocks 7 are installed in conjunction with the adjustment devices.

[0038] Multiple mounting blocks 34 are symmetrically fixedly connected to the bottom of the base 1, which facilitates the installation and fixation of the whole to the road surface.

[0039] Working principle and usage process of this invention:

[0040] In use, the adjusting block 17 is pressed with a tool. The second spring 15 is initially compressed. The movement of the adjusting block 17 can drive the fixed block 18 to move, and the second spring 15 is further compressed. The top block 23 and the mounting groove 4 move relative to each other, and the top block 23 separates from the limiting block 7. As the adjusting block 17 moves, the first inclined groove 25 on the surface of the top block 23 contacts the third inclined groove 27 on the surface of the lifting block 6 and slides relative to each other. Then, the second inclined groove 26 contacts the surface of the fourth inclined groove 28, the fixed block 18 contacts the surface of the inclined block 31 and slides relative to each other, and the circular block 30 moves relative to the column groove 8. The limiting column 32 and the... After the lifting plate 10 separates and the fixing block 18 contacts the bottom of the mounting groove 4, the upper cover 2 is pulled upward through the round hole 33. The lifting block 6 and the top block 23 move simultaneously, and the lifting block 6 moves relative to the sliding groove 5 until the lifting block 6 moves to the other end of the sliding groove 5. The second inclined groove 26 and the fourth inclined groove 28 slide relative to each other. Then, the second inclined groove 26 and the fourth inclined groove 28 separate, and the top block 23 slides over the surfaces of the lifting block 6 and the limiting block 7 in sequence. The protrusion 13 separates from the mounting groove 4, completing the disassembly of the upper cover 2. Under the action of the first spring 9, the terminal 11 contacts the surface of the upper cover 2. As the upper cover 2 moves, the base 1 extends out.

[0041] Connect the terminal of the testing instrument to the terminal 11 for testing. After the test is completed, move the top cover 2 from top to bottom. The protrusion 13 cooperates with the mounting groove 4, and the vertical groove 14 cooperates with the limiting block 7 to limit the movement. The lifting plate 10 moves below the limiting post 32 and returns to the initial state.
