Technical Field

[0001] The utility model relates to the technical field of power transmission line grounding, in particular to a novel grounding structure for power transmission lines. Background Art

[0002] When transmitting electric current, wires are often cut and spliced ​​due to different connection devices and the length of the connection distance. Some wire harness connection points are buried deep underground. When assembling them with the upper equipment, a grounding structure is required as an intermediate conversion. The previous grounding tools were fixed in position, making it difficult to adjust their position during maintenance and installation. It was also inconvenient for passers-by to walk and carry equipment, so they needed to be modified. Utility Model Content

[0003] The purpose of the utility model is to provide a new grounding structure for a power transmission line to solve the problems raised in the above background technology.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A novel grounding structure for a power transmission line comprises a housing 1 and a junction block 2 arranged inside the housing 1, wherein one end of the junction block 2 is hingedly connected to the inner wall of the housing 1;

[0006] The junction block 2 has an inner cavity 4, a notch 3 is provided at the lower left corner and the upper right corner of the inner cavity 4, a receiving groove 14 is provided on the side wall of the junction block 2 on one side of the notch 3, and a track 17 is provided on the side wall of the junction block 2 on the other side of the notch 3;

[0007] A connecting rod 15 is movably inserted inside the receiving groove 14 , and a clamping piece 16 is fixedly sleeved on the other end of the connecting rod 15 . A clamping block 18 is disposed on the other end of the clamping piece 16 , and the clamping block 18 is embedded in the track 17 .

[0008] Through the above technical solution, the hinged terminal block 2 is taken out from the inside of the housing 1, and the wire harness is introduced into the inner cavity 4 from the notch 3 at the upper right corner, and then led out from the notch 3 at the lower left corner, so as to be assembled with the wire ends underground. The clip 16 can move horizontally along the track 17, and the connecting rod 15 can move horizontally along the receiving groove 14. The connecting rod 15 in the receiving groove 14 can be pulled to move to the other end in advance, and the clip 16 is guided to move along the track 17 by the push of the connecting rod, thereby expanding the clamping distance. After the wire harness passes through the notch, the connecting rod is pulled to reset the clip to fix the wire.

[0009] Furthermore, two groups of springs 23 are arranged between the clip 16 and the notch 3 near one end of the accommodating groove 14 , and the two groups of springs 23 are symmetrically arranged about the connecting rod 15 .

[0010] Through the above technical solution, when the wire harness needs to be fixed after passing through the slot, the connecting rod and the clip can be easily reset through the setting of the spring, and the clip can be automatically reset to an appropriate width to fix the wire, reducing manual operation and saving time and effort; secondly, the spring setting can prevent external vibration from affecting the wiring effect and improve the stability of the device.

[0011] Furthermore, the connecting rod 15 includes a push rod and a limiting pull rod arranged perpendicular to the push rod. The push rod is laterally inserted in the accommodating groove 14 and moves along the inner wall of the wiring block 2. The limiting pull rod is located outside the accommodating groove 14 and moves along the outer wall of the wiring block 2.

[0012] Through the above technical solution, firstly, the setting of the limit pull rod plays a limiting role; secondly, the limit pull rod plays the role of a handle, which facilitates the operation of the entire connecting rod.

[0013] Furthermore, a storage chamber 11 is transversely arranged on the top of the housing 1, and a cover plate 12 is movably arranged at the opening of the storage chamber 11; a limiting groove 10 is opened on the upper part of the cover plate 12, and a limiting block 9 is inserted into the limiting groove 10.

[0014] Through the above technical solution, the setting of the limiting groove 10 is used to pass the wiring harness from here, and secondly, the cover is limited and locked by cooperating with the limiting block 9.

[0015] Furthermore, slide grooves 6 are symmetrically opened on the two side walls at both ends of the shell 1, and a limit rod 7 is arranged between the two opposite slide grooves 6, and the two ends of the limit rod 7 are respectively slidably set in the slide grooves 6 on both sides; sliders 8 matching the slide grooves 6 are fixedly welded at both ends of the cover plate 12, and one end of the slider 8 is sleeved on the limit rod 7; circular grooves 24 are respectively opened on the bottom wall of the storage chamber 11 near the two ends, and balls 13 are rolled in the circular grooves 24, and the top of the ball 13 contacts the bottom of the cover plate 12.

[0016] Through the above technical solution, the cover plate needs to be closed after the entire threading is completed. Under the lubrication of the ball bearing below, the cover plate can be quickly and smoothly pushed horizontally and closed in cooperation with the slider sleeved on the limit rod, and then limited by the limit block to avoid damage to the internal components and also play a dust-proof role.

[0017] Furthermore, a storage frame 19 is disposed inside the housing 1 , a cavity 20 is disposed inside the storage frame 19 , and a layer of hygroscopic particles 21 is filled inside the cavity 20 .

[0018] Through the above technical solution, the humidity of the internal environment is judged by the hygroscopic particles to ensure that the internal environment is sufficiently dry. That is, the hygroscopic particles of the utility model are made of color-changing silica gel. If the hygroscopic particles obviously change color, it proves that the humidity is high and needs to be replaced, so as to ensure that the environment inside the component is sufficiently dry at all times and prevent the metal electrode from getting damp.

[0019] Furthermore, gauze meshes 5 are respectively provided on both side walls of the inner cavity 4 , and a breathable membrane 22 is provided behind the storage frame 19 . The breathable membrane 22 is arranged opposite to and communicated with the gauze meshes 5 .

[0020] Through the above technical solution, a breathable membrane is provided on one side of the storage frame, and the breathable membrane is opposite to the gauze on the side of the wiring block, so the internal environment of the entire grounding structure is connected, which is convenient for filling the cavity 20 of the storage frame 19 with hygroscopic particles and replacing the hygroscopic particles at any time to ensure internal dryness and prevent the metal electrode from getting damp.

[0021] Compared with the prior art, the power transmission line grounding structure of the utility model has the following beneficial effects:

[0022] (1) By providing notches at the lower left corner and the upper right corner of the inner cavity, the hinged wiring block is taken out from the inside of the shell, and the wiring harness is introduced into the inner cavity from the notch at the upper right corner and then led out from the notch at the lower left corner so as to be assembled with the wire ends underground. The connecting rod in the receiving groove can be pulled horizontally along the receiving groove in advance, and the spring-supported clip is guided by the object to expand the clamping distance. After the wiring harness passes through, the connecting rod is released and the clip is allowed to reset to fix the wire, so as to prevent external vibration from affecting the wiring effect;

[0023] (2) A storage chamber is provided at the top of the housing, and the limit block in the limit groove is opened. The wiring harness connected to the grounding structure is pre-passed through the chamber and then assembled. After the assembly is completed, the cover plate is pushed horizontally along the storage chamber. Under the lubrication of the ball bearing below, the cover plate cooperates with the slider sleeved on the limit rod to close the cover plate quickly and smoothly, thereby protecting the internal components and extending the service life.

[0024] (3) A storage frame is fixedly connected at both ends of the shell, and a breathable membrane is provided at one end of the storage frame, which is opposite to the mesh at both ends of the wiring block. Therefore, the internal environment of the entire grounding structure is connected, and moisture-absorbing particles can be filled in the cavity of the storage frame. This material is made of color-changing silica gel. If the color changes significantly, it proves that the moisture is excessively absorbed and needs to be replaced, so as to ensure that the environment inside the component is dry enough at all times.

[0025] In summary, the grounding structure for power transmission lines of the utility model not only realizes the rapid splicing of wiring harnesses and protects connectors, but also realizes a dry environment inside the grounding structure and reduces the failure rate.
