Description

Technical Field

[0001] The utility model relates to the technical field of pipeline drainage monitoring, in particular to a buried pipeline drainage device. Background Art

[0002] A drain is an electrical device that eliminates the effects of stray current on metal structures and cathodic protection systems. It can also be used to drain leakage current from the protected cable into the power grid that generates the current. It also means that since leakage current can only be discharged in one direction, it can prevent reverse current from flowing into the cable sheath.

[0003] However, in prior art drainers, such as those disclosed in Publication No. CN219918394U or Publication No. CN212436047U, the pins of the solid-state decoupler are secured to the wires via bolts. Since drainers are typically exposed outdoors, rusted bolts make it difficult to separate the bolts from the pins. Furthermore, after connection, the solid-state decoupler must be bolted through its side panels to the inner wall of the housing, further hindering assembly and disassembly of the solid-state decoupler. Utility Model Content

[0004] The purpose of the present utility model is to provide a buried pipeline drainage device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a buried pipeline drainage device, comprising a support rod, a connecting assembly mounted on the support rod, and a box connected to the connecting assembly, wherein a solid-state decoupler is provided inside the box; the pins of the solid-state decoupler are connected to a plug-in connector provided on the bottom surface of the box, and the other side of the solid-state decoupler is connected to the top surface of the box via a support member; the plug-in connector includes a fixing portion, and the fixing portion is also provided with a socket for facilitating the insertion of the pins of the solid-state decoupler; the socket extends into the connecting assembly via a conductive sheet, and a screw hole is further provided below the conductive sheet.

[0006] As a preferred technical solution of the present invention: the support member includes a connecting plate and a contact plate, and a spring is provided between the connecting plate and the contact plate.

[0007] As a preferred technical solution of the present invention: the fixing portion, the connecting plate and the contact plate are all insulating plates.

[0008] As a preferred technical solution of the present invention: the connecting plate is movably mounted on the top surface inside the box.

[0009] As a preferred technical solution of the present invention: the connecting assembly includes a connecting portion, and the connecting portion is connected to a connecting piece through a connecting pipe, and is connected to the box body through the connecting piece.

[0010] As a preferred technical solution of the present invention: the interior of the connecting portion is a hollow structure, and a door body is further provided on the connecting portion.

[0011] As a preferred technical solution of the present invention: the connecting portion is movably connected to a connecting seat provided at the upper end of the support rod.

[0012] By adopting the above technical solution, the present invention has the following beneficial effects: once the pins of the solid-state decoupler are inserted into the plug-in connector, the solid-state decoupler and the plug-in connector can be quickly connected. After the connection, the support member is used to force the pins of the solid-state decoupler to press against the plug-in connector. This makes the solid-state decoupler easy to install, solving the problem of the limited space in the box that is not conducive to connecting the wires to the pins of the solid-state decoupler; and it is also easy to disassemble, solving the problem that the existing method requires the use of bolts for fixed connection, which makes it inconvenient to disassemble the solid-state decoupler later. In particular, the provision of the support member ensures that the solid-state decoupler has the advantage of stable and reliable position after being connected to the socket, thereby eliminating the need for the solid-state decoupler to be connected to the box, thereby simplifying the installation method of the solid-state decoupler in the prior art.

[0020] See also Figure 1-5 The utility model provides an embodiment of a buried pipeline drainage device, comprising a support rod 1, a connecting assembly 2 installed on the support rod 1, and a box body 3 connected to the connecting assembly 2, wherein a solid decoupler 31 is provided inside the box body 3; the pins of the solid decoupler 31 are connected to the plug-in connector 34 provided on the bottom surface of the box body 3, and the other side of the solid decoupler 31 is connected to the top surface of the box body 3 through a supporting member 32; the plug-in connector 34 includes a fixing portion 36, and the fixing portion 36 is also provided with a socket 37 for facilitating the insertion of the pins of the solid decoupler 31; the socket 37 extends into the connecting assembly 2 through a conductive sheet 35, and a screw hole 38 is further provided below the conductive sheet 35.

[0021] In summary, once the pins of the solid-state decoupler 31 are inserted into the connector 34, a quick connection between the solid-state decoupler and the connector 34 is achieved. After the connection, the support member 32 is used to force the pins of the solid-state decoupler 31 against the connector 34. This facilitates installation of the solid-state decoupler 31, solving the problem of the limited space in the box hindering connection between the wires and the pins of the solid-state decoupler. Furthermore, it facilitates disassembly, solving the problem of the existing method requiring bolted connection, which makes it difficult to disassemble the solid-state decoupler 31 later.

[0022] In particular, the arrangement of the support member 32 ensures that after the solid-state decoupler 31 is connected to the socket 37 , the solid-state decoupler 31 has the advantage of being stable and reliable in position, thereby eliminating the need for the solid-state decoupler to be connected to the box, thereby simplifying the installation method of the solid-state decoupler in the prior art.

[0023] Specifically, the support member 32 includes a connecting plate 33 and a contact plate 310, with a spring 39 interposed between the connecting plate 33 and the contact plate 310. Therefore, the elastic force of the spring 39 constantly forces the pins of the solid-state decoupler 31 to rest firmly within the socket 37. Furthermore, the fixing portion 36, the connecting plate 33, and the contact plate 310 are all insulated. This prevents electrical power from flowing outside the support rod 1 and the housing 3. The fixing portion 36 is in contact with the bottom surface of the housing 3 to prevent the connector 34 from falling out of the housing 3 when the solid-state decoupler 31 is inserted.

[0024] Furthermore, since the connecting plate 33 is movably mounted on the top surface inside the box body 3, the assembly and disassembly of the support member 32 is also simple and convenient. In addition, in order to improve the stability of the support member 32, the support member 32 can be fixed by passing the connecting plate 33 through the box body 3.

[0025] On the basis of the above solution, the connecting assembly 2 includes a connecting portion 21, and the connecting portion 21 is connected to the connecting piece 23 through the connecting pipe 20, and is connected to the box body 3 through the connecting piece 23. Furthermore, the interior of the connecting portion 21 is a hollow structure, and a door body 22 is further provided on the connecting portion 21.

[0026] In summary, after the wire connected to the buried pipe passes through the support rod 1, it enters the connecting pipe 20, and then is connected to the screw hole 38 by a bolt to fix the wire on the conductive plate 35. At the same time, the connecting portion 21 is a hollow structure, so the hollow structure can be used to protect the connection between the wire and the conductive plate 35. At the same time, the door body 22 can be directly opened during maintenance to facilitate the connection of the detection equipment to the conductive plate 35. At the same time, one end of the conductive plate 35 is connected to the socket 37, and the lower end of the conductive plate 35 extends directly to the inside of the connecting portion 21, and then the conductive plate 35 is connected to the buried pipe wire. Therefore, while facilitating wire connection and reducing connection points, it can also optimize the line layout between the solid-state decoupler 31 and the buried pipe wire. At the same time, when the connector 34 is damaged, it can be directly replaced.

[0027] In addition, since the connecting portion 21 is movably connected to the connecting seat 4 provided at the upper end of the support rod 1, support rods 1 of different heights can be installed on the connecting assembly 2. Specifically, the external portion of the connecting seat 4 has an external thread, which is connected to the internal thread on the inner wall of the connecting portion 21 to complete the connection between the support rod 1 and the connecting assembly 2. Among them, the connecting piece 23 is preferably a flange.

[0028] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
