Description

Technical Field

[0001] This utility model relates to the field of data collection technology for buried metal pipelines, specifically to a device for collecting information on buried metal pipelines. Background Technology

[0002] Buried metal pipelines are widely used in important sectors of the national economy such as oil, natural gas, water supply, and heating. In order to monitor the pipeline status in real time (such as corrosion status, cathodic protection effect, leakage risk, etc.), it is necessary to install information acquisition devices (such as potential test piles, current test piles, corrosion monitoring probe terminals, etc.) along the pipeline to collect key parameters such as pipeline potential, current, corrosion rate, temperature, and stress.

[0003] Currently, common buried pipeline information acquisition devices typically include a base and an acquisition terminal installed inside. This acquisition terminal needs to be reliably connected to the lead wires (such as reference electrode lead wires, test piece lead wires, pipeline connection wires, etc.) pre-embedded on the pipeline body via cables in order to achieve effective acquisition of pipeline information.

[0004] However, existing buried pipeline information acquisition devices have the following shortcomings in practical application and operation and maintenance. First, installation and transportation are inconvenient: traditional devices often adopt an integrated design with a long overall length. When installing and transporting them in confined spaces such as in the field or densely populated pipeline areas, operation is inconvenient, resulting in low installation efficiency. Second, the wiring operation space is limited: the wiring space inside the device is usually very small. When connecting the acquisition terminal cable to the pre-buried cable led out from the pipeline, the range of movement of operators (such as hands and tools) is severely restricted. This confined space makes wiring work difficult and time-consuming, further affecting installation efficiency. Therefore, a device is needed to solve the above problems. Utility Model Content

A wire hole is provided on the back of the mounting compartment, and the mounting compartment communicates with the interior of the wiring compartment through the wire hole.

[0008] Optionally, the adjustment mechanism includes an adjustment rod, a slide rail, and a slider. The adjustment rod is rotatably connected to the back of the terminal block via a rotating shaft. The slide rail is fixedly connected to the inner wall of the terminal compartment. The slider is slidably connected to one side of the slide rail.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a buried metal pipeline information collection device, including a base 1, a wiring section 2 and an equipment section 3. The equipment section 3 and the base 1 are respectively threaded to the upper and lower sections of the wiring section 2. The base 1, the wiring section 2 and the equipment section 3 are all hollow structures.

[0025] The wiring section 2 has a wiring compartment 4 inside, and a wiring board 5 is movably connected inside the wiring compartment 4. The inner wall of the wiring compartment 4 is provided with an adjustment mechanism to adjust the position of the wiring board 5. A mounting box 6 is fixedly connected to one side of the equipment section 3. The mounting box 6 has a mounting compartment 7 inside to fix the acquisition terminal. A wire hole 8 is provided on the back of the mounting compartment 7. The mounting compartment 7 communicates with the inside of the wiring compartment 4 through the wire hole 8.

[0026] The base 1 is fixed on the ground. The wiring section 2 and the equipment section 3 are installed on the base 1 in sequence. The acquisition terminal is installed in the installation compartment 7. The connection wire of the acquisition terminal passes through the wire hole 8 on the back of the installation compartment 7 and enters the wiring compartment 4. The cable of the pre-buried pipe passes upward from the hollow position in the middle of the base 1 into the wiring compartment 4. The connection wire of the acquisition terminal is connected to the connection wire of the pre-buried pipe through the wiring plate 5, thereby collecting information of the pre-buried pipe. It can improve the warning effect after the pipe is anoly corroded. During the wiring process, the wiring plate 5 can be pulled outward by the adjustment mechanism to increase the operating range and make wiring more convenient, reducing the interference of the outer shell of the wiring section 2 on the wiring process. The model of the acquisition terminal can be CYZD-Y intelligent cathodic protection acquisition terminal.

[0027] In this embodiment, as a preferred solution, the adjustment mechanism includes an adjustment rod 9, a slide rail 10, and a slider 11. The adjustment rod 9 is rotatably connected to the back of the terminal block 5 via a rotating shaft. The slide rail 10 is fixedly connected to the inner wall of the terminal compartment 4. The slider 11 is slidably connected to one side of the slide rail 10. The section of the adjustment rod 9 away from the terminal block 5 is rotatably connected to the slider 11. A limit block 12 is fixedly connected to the surface of the slide rail 10 to limit the sliding distance of the slider 11. The surface of the terminal block 5 is provided with multiple terminals 13 for electrical connection with the acquisition terminal. An installation port is opened on one side of the terminal section 2. A lever 14 is rotatably connected to the back of the terminal block 5. When the lever 14 is matched with the edge of the installation port, the limit block 12 stops the slider 11 so that the terminal block 5 is supported outside the installation port.

[0028] When the connector plate 5 is pulled outward, the adjusting rod 9 and the slider 11 will move synchronously. As the connector plate 5 is pulled outward, the two sliders 11 will slide towards the middle synchronously. After the connector plate 5 is pulled outward, rotate the lever 14 on the back of the connector plate 5. After the lever 14 is rotated out, it can be locked at the opening of the connector compartment 4, thereby fixing the position of the connector plate 5 to prevent the connector plate 5 from accidentally retracting during the wiring process. Connect the cables on the acquisition terminal and the pre-buried pipeline to the terminal post 13 and fix them with bolts. After the wiring is completed, rotate the lever 14 back to the back of the connector plate 5 and push the connector plate 5 back into the connector compartment 4. Then close the protective door 16. The position where the slider 11 contacts the slide rail 10 is provided with a friction pad to provide a certain damping force to prevent the connector plate 5 from accidentally sliding in the connector compartment 4. The limit block 12 limits the position of the slider 11 to prevent the slider 11 from moving to the dead zone and causing the position of the connector plate 5 to be stuck.

[0029] In this embodiment, as a preferred option, a barrier plate 15 is fixedly connected to the surface of the wire hole 8, and the barrier plate 15 is used to constrain the cable of the acquisition terminal.

[0030] The barrier 15 consists of multiple sheet-shaped rubber plates. The multiple barrier plates 15 surround the wire hole 8. When the cable passes through, the barrier plates 15 that are blocked by the cable bend back to one side to allow the cable to pass through, while the barrier plates 15 that are not blocked remain in their original positions. This reduces the size of the wire hole 8 and fixes the position of the cable, reducing cable sway.

[0031] In this embodiment, as a preferred option, both the front of the mounting box 6 and the front of the wiring segment 2 are connected to a protective door 16 by hinges, and a sealing gasket 17 is fixedly connected to the inner wall of the protective door 16.

[0032] After the protective door 16 is closed, the sealing gasket 17 can seal the gap between the protective door 16 and the installation chamber 7, preventing external rainwater from entering.

[0033] In this embodiment, as a preferred option, the surface of the base 1 is provided with fixing holes 18, and the lower surface of the base 1 is detachably connected with ground nails 19.

[0034] The ground nail 19 is detachable, and the corresponding installation method can be selected according to different situations. When on flat surfaces such as cement floors, the ground nail 19 can be removed and the base can be fixed in position with bolts. On unhardened surfaces, the ground nail 19 can be used to fix the position of the device, reducing the shaking of the base 1.

[0035] In this invention, the working steps of the device are as follows:

[0036] 1. When using, fix the base 1 in the corresponding position according to the exit position of the pre-buried pipe cable, so that the cable passes through the middle of the base 1. Then fix the wiring section 2 and the equipment section 3 on the base 1 in sequence to ensure that the cable of the pre-buried pipe passes through the wiring compartment 4.

[0037] 2. Install the acquisition terminal in the installation compartment 7, and pass the cable of the acquisition terminal through the cable hole 8 on the back into the wiring compartment 4. Pull the wiring plate 5 outward and rotate the lever 14 to fix the position of the wiring plate 5. Then connect the cable of the acquisition terminal to the cable of the pre-buried pipe and fix it to the terminal block 13 with bolts.

[0038] 3. After securing it, rotate the lever 14 to retract the lever 14, then push the wiring board 5 back into the wiring compartment 4, and close the protective door 16.

[0039] The specific embodiments provided by this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
