Description

Technical Field

[0001] The utility model relates to the technical field of cathode protection, in particular to a potential connection device for cathode protection of long-distance pipelines. Background Art

[0002] In the cathodic protection of long-distance pipelines, a potential connection device is needed as a connection point. The cathodic protection device needs to be placed underground. Generally, the cathode needs to be inserted into the connection device, and then the connection is protected. At this time, a potential connection device is needed.

[0003] After searching, the Chinese patent publication number CN217173875U was found. It discloses a potential connection device for cathodic protection of long-distance pipelines, including a protection device body, a cover plate movably inserted into the inner surface of the protection device body, a handle fixedly welded to the top outer surface of the cover plate, a guide tube fixedly inserted into the inner surface of the protection device body, a slide groove formed on the inner surface of the protection device body, a limit block fixedly welded to the bottom outer surface of the cover plate, and a connection device body movably connected to the top outer surface of the two stabilizing bars. This patent moves the cover plate upward by moving the handle upward, and can guide water into the guide tube to drain the water, thereby achieving the effect of facilitating the protection of the connection device body and preventing water from entering the device.

[0004] In the above-mentioned prior art solution, the two slides are slid toward each other, and then the wires are extended into the interior of the protective device body through the wire tube. However, in actual use, the two slides need to be fully slid toward each other so that the two pressure rods can be fully retracted into the interior of the protective device body. Otherwise, the two pressure rods will cause the inner side wall of the wire tube to be convex. At this time, when the wires are extended into the interior of the wire tube, the pressure rods will block the movement of the wires, making installation inconvenient. Utility Model Content

[0005] In order to solve the above technical problems, the utility model proposes a potential connection device for cathodic protection of long-distance pipelines. The wire pipe is rotated so that the inclined end of the wire pipe faces the top. At this time, the wire is inserted into the interior of the wire pipe through the inclined end of the wire pipe. Under the guidance of the guide plate, the wire passes over the installation plate and enters the interior of the protective outer frame, making it convenient to place the wire into the interior of the protective outer frame, thereby achieving the effect of facilitating the connection and installation of the wire.

[0006] The technical solution to achieve the purpose of the utility model is: a potential connection device for cathodic protection of long-distance pipelines, including a protective outer frame, a cover plate is slidably installed on the top of the protective outer frame, a mounting seat is fixedly installed on the inner bottom wall of the protective outer frame, and the top of the mounting seat is fixedly connected to the connecting device body by bolts, a wire pipe is rotatably installed on the side wall of the protective outer frame, and the end of the wire pipe away from the protective outer frame is distributed in an inclined shape, and a mounting plate is fixedly installed on the end of the side wall of the wire pipe close to the mounting seat, and the mounting plate is located at the top end of the wire pipe, and a limiting groove is provided inside the mounting plate, and a limiting rod is slidably installed inside the limiting groove, and a pressure plate is fixedly connected to the bottom wall of the limiting rod, and a guide plate corresponding to the side wall of the wire pipe is fixedly installed on the side wall of the mounting plate, and the side wall of the guide plate is inclined.

[0007] In some embodiments, a bottom wall surface of the mounting plate is provided with a receiving groove, and a weight-increasing block is slidably installed inside the receiving groove.

[0008] In some embodiments, a connecting groove is provided on the side wall of the weight-increasing block, an inner wall of the connecting groove is fixedly connected to a compression spring, and an end of the compression spring away from the pressure plate is fixedly connected to the inner wall of the accommodating groove.

[0009] In some embodiments, a connecting plate is provided on the side wall of the protective outer frame, and a positioning block is fixedly mounted on one end of the connecting plate close to the wire pipe, and the positioning block fits into an inclined side wall surface of the wire pipe.

[0010] In some embodiments, a rotating frame is rotatably mounted on the side wall of the protective outer frame, and the connecting plate is fixedly mounted on the side wall of the rotating frame.

[0011] In some embodiments, a positioning plate is fixedly mounted on the side wall of the wire tube, and the positioning plate is rotatably mounted inside the protective outer frame.

[0012] Compared with the prior art, the present invention has the following significant advantages:

[0013] First, the utility model rotates the wire tube so that the inclined end of the wire tube faces the top, and the mounting plate is therefore at the bottom. The pressure plate moves downward due to the influence of gravity. At this time, the wire is inserted into the interior of the wire tube through the inclined end of the wire tube. Under the guidance of the guide plate, the wire passes over the mounting plate and enters the interior of the protective outer frame, which makes it convenient to place the wire into the interior of the protective outer frame and facilitates the connection and installation of the wire. After the wire is installed, the wire tube is rotated so that the inclined end of the wire tube faces the bottom. At this time, the mounting plate faces upward, and the pressure plate moves downward due to the influence of gravity. The pressure plate is therefore pressed on the surface of the wire, and under the guidance of the wire tube, the wire has multiple turns and fits with the side wall of the wire tube, ensuring the stable position of the wire and facilitating the installation of the wire; solving the problem that the existing wire is difficult to install.

[0014] Second: The utility model increases the weight of the pressing plate by adding weight blocks, thereby increasing the pressure of the pressing plate so that the pressing plate can compact the wire; by utilizing the elasticity of the extrusion spring, the pressure applied by the pressing plate on the wire is further increased, thereby further ensuring the stability of the wire.

The side wall of the guide plate 18 is inclined; the wire tube 3 is rotated so that the inclined end of the wire tube 3 faces the top, and the mounting plate 10 is therefore at the bottom. The pressing plate 11 moves downward due to the influence of gravity. At this time, the wire is inserted into the interior of the wire tube 3 through the inclined end of the wire tube 3. Under the guidance of the guide plate 18, the wire passes over the mounting plate 10 and enters the interior of the protective outer frame 1, which makes it convenient to place the wire into the interior of the protective outer frame 1 and facilitate the connection and installation of the wire. After the wire is installed, the wire tube 3 is rotated so that the inclined end of the wire tube 3 faces the bottom. At this time, the mounting plate 10 faces upward, and the pressing plate 11 moves downward due to the influence of gravity. The pressing plate 11 is therefore pressed on the surface of the wire, and the wire is guided by the wire tube 3 at multiple turns and fits against the side wall of the wire tube 3, ensuring the stable position of the wire and facilitating the installation of the wire.

[0026] like Figure 2-Figure 5 As shown, in one embodiment, in order to ensure the stable position of the wire tube 3, a positioning plate 4 is fixedly installed on the side wall of the wire tube 3, and the positioning plate 4 is rotatably installed inside the protective outer frame 1; the position of the wire tube 3 is restricted by the positioning plate 4 to prevent the wire tube 3 from falling off from the inside of the protective outer frame 1.

[0027] like Figure 3-Figure 5 As shown, in one embodiment, in order to ensure the stable position of the pressure plate 11, a receiving groove 14 is provided on the bottom wall of the mounting plate 10, and a weight block 15 is slidably installed inside the receiving groove 14; the weight of the pressure plate 11 is increased by the weight block 15, and the pressure of the pressure plate 11 is increased, so that the pressure plate 11 can compact the wire; a connecting groove 16 is provided on the side wall of the weight block 15, and the inner wall of the connecting groove 16 is fixedly connected to an extrusion spring 17, and the end of the extrusion spring 17 away from the pressure plate 11 is fixedly connected to the inner wall of the receiving groove 14; by utilizing the elasticity of the extrusion spring 17, the pressure applied by the pressure plate 11 on the wire is further increased, and the stability of the wire is further ensured.

[0028] like Figure 1-Figure 5As shown, in one embodiment, in order to ensure the stable position of the wire tube 3, a connecting plate 7 is provided on the side wall of the protective outer frame 1, and a positioning block 6 is fixedly installed on the end of the connecting plate 7 close to the wire tube 3, and the positioning block 6 is in contact with the inclined side wall of the wire tube 3; the position of the wire tube 3 is restricted by the positioning block 6, so as to ensure the stable position of the wire tube 3 and avoid the shaking of the position of the wire tube 3, which leads to the unstable position of the wire; a rotating frame 5 is rotatably installed on the side wall of the protective outer frame 1, and the connecting plate 7 is fixedly installed on the side wall of the rotating frame 5; the position of the connecting plate 7 is restricted by the rotating frame 5, so that the positioning block 6 can rotate synchronously with the wire tube 3, thereby facilitating the positioning of the wire tube 3.

[0029] The specific working method is: rotate the wire tube 3 so that the inclined end of the wire tube 3 faces the top, and the mounting plate 10 is therefore at the bottom. The pressure plate 11 moves downward due to the influence of gravity. At this time, the wire is inserted into the interior of the wire tube 3 through the inclined end of the wire tube 3. Under the guidance of the guide plate 18, the wire passes over the mounting plate 10 and enters the interior of the protective outer frame 1, which makes it convenient to place the wire into the interior of the protective outer frame 1 and facilitate the connection and installation of the wire. After the wire is installed, rotate the wire tube 3 so that the inclined end of the wire tube 3 faces the bottom. At this time, the mounting plate 10 faces upward, and the pressure plate 11 moves downward due to the influence of gravity. The pressure plate 11 is therefore pressed on the surface of the wire, and the wire is guided by the wire tube 3 at multiple turns and fits against the side wall of the wire tube 3, ensuring the stable position of the wire and facilitating the installation of the wire.
