Abstract
Description
Technical Field
[0001] This application relates to the field of cable support technology, and in particular to a line support structure for a substation equipment room. Background Technology
[0002] Underground cable support systems in substations typically include the following types: Cable manholes: Used for burying and protecting cables, securing them underground, and providing necessary ventilation and maintenance access. Cable trenches: A series of continuous trenches laid underground for installing and maintaining cables. Trenches are typically made of concrete or steel. Cable trench covers: Covers located on top of cable trenches to cover and protect the cables within. Covers are typically made of steel plate or concrete. Cable supports: Support structures used to secure cables underground, using various clamps or fixing devices to support and protect the cables. The design and installation of these underground cable support systems must comply with relevant electrical engineering codes and standards to ensure the safety and reliability of the cables.
[0003] Patent document CN117277197A discloses an underground line support device for substations, which uses clamps to hold and fix cables. This has certain advantages, but also some shortcomings. For example, the clamping of cables between any two adjacent clamps is interconnected. That is, when the locking screw is loosened, the entire clamp is in a non-clamped state, and when the locking screw is tightened, the entire clamp is in a clamped state. During the process of clamping cables, clamping only occurs when all cables are placed between the clamps. This makes it very easy for cables placed in the clamps first to slip out when cables are placed in the clamps later, causing clamping failure. Utility Model Content
[0004] The purpose of this application is to provide a line support structure for a substation equipment room to solve the above-mentioned problems.
[0005] To achieve the above objectives, the technical solution of this application is as follows:
[0006] A line support structure for a substation equipment room includes a locking assembly and a clamping assembly. The clamping assembly includes a sliding rod and a plurality of clamping plates slidably disposed on the sliding rod. A clamping cavity is formed between two adjacent clamping plates, and a spring is disposed in the clamping cavity. The spring is in a stretched state. The locking assembly is disposed at the top of the clamping assembly for pressing the plurality of clamping plates.
[0007] Preferably, the clamping plate has a notch, and the sliding rod is located in the notch; a snap-fit element is engaged with the notch at the side opening of the clamping plate.
[0008] Preferably, the locking assembly includes a support plate with a through slot, a rotating shaft rotatably disposed in the slot, an abutment on the rotating shaft, and an abutment surface at one end of the abutment facing the clamping assembly.
[0009] Preferably, the rotating shaft is provided with a sliding plane, the abutment is slidably engaged with the sliding plane, the abutment is provided with a long groove, a screw is provided in the long groove, and the screw passes through the long groove and is screwed onto the sliding plane.
[0010] Preferably, the bottom of the sliding rod is screwed with two first nuts, and one of the clamping plates at the bottom of the clamping assembly is located between the two first nuts; the top of the sliding rod is screwed with two second nuts, and the support plate is located between the two second nuts.
[0011] Preferably, buffer pads are provided on both the upper and lower walls of the clamping cavity.
[0012] Preferably, it also includes a base connected to the end of the clamping assembly away from the locking assembly.
[0013] The line support structure for a substation equipment room disclosed in this application has a spring installed in the clamping cavity. The spring is in a stretched state, meaning that the presence of the spring can cause adjacent clamping plates to tend to move closer to each other. Therefore, when clusters of lines are placed in the clamping cavity, the clamping cavity can pre-clamp the lines under the action of the spring, thereby avoiding the impact on the already clamped lines when clamping lines in other clamping cavities later, thus ensuring the stability of the clamping.

[0021] The present application will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present application, and therefore only show the components relevant to the present application.
[0022] like Figure 1-5 As shown, a line support structure for a substation equipment room includes a locking assembly 1 and a clamping assembly 2. The clamping assembly 2 includes a sliding rod 11 and a plurality of clamping plates 20 slidably disposed on the sliding rod 11. A clamping cavity 7 is formed between two adjacent clamping plates 20. A spring 5 is provided in the clamping cavity 7 and the spring 5 is in a stretched state. The locking assembly 1 is disposed at the top of the clamping assembly 2 for pressing the plurality of clamping plates 20.
[0023] The clamping component 2 is used to clamp the line, and the locking component is used to lock the clamping component 2 to ensure the fixation of the line.
[0024] A clamping cavity 7 is formed between two adjacent clamping plates 20, and cables of different clusters are clamped in the clamping cavity 7.
[0025] The clamping plate 20 is slidably mounted on the sliding rod 11. When the distance between the two clamping plates 20 forming the clamping cavity 7 is shortened, the line will be gradually pressed and fixed.
[0026] Specifically, a spring 5 is provided in the clamping cavity 7. The spring 5 is in a stretched state, meaning that the presence of the spring 5 can cause two adjacent clamping plates 20 to tend to move closer to each other. Therefore, when clusters of wires are placed in the clamping cavity 7, the clamping cavity 7 can pre-clamp the wires under the action of the spring 5, thereby avoiding affecting the already clamped wires when clamping them in other clamping cavities 7 later, thus ensuring the stability of the clamping.
[0027] In some further embodiments, the clamping plate 20 is provided with a notch 200, and the sliding rod 11 is located in the notch 200; a snap-fit member 22 is snapped into the notch 200 at the side opening of the clamping plate 20.
[0028] One end of the clamping plate 20 is provided with a notch 200, and the sliding rod 11 is provided in the notch 200. When it is necessary to remove all the lines, the sliding rod 11 can be directly moved out of the notch 200 to quickly remove all the lines.
[0029] The snap-fit component 22 is snapped onto the notch 200. When no force is applied to the sliding rod 11, the sliding rod 11 can be well constrained by the snap-fit component 22. When it needs to be removed, the sliding rod 11 can directly push the snap-fit component 22 off the notch 200.
[0030] In some further embodiments, the locking component 1 includes a support plate 10, a slot 15 extending through the support plate 10, a rotating shaft 13 rotatably disposed in the slot 15, an abutment 14 disposed on the rotating shaft 13, and an abutment plane 140 disposed on one end of the abutment 14 facing the clamping component 2.
[0031] The abutment 14 has a certain length. When the rotating shaft 13 is rotated, one end of the abutment 14 with the abutment plane 140 gradually approaches the uppermost clamping plate 20. When the length direction of the abutment 14 is perpendicular to the clamping plate 20, the abutment plane 140 just abuts against the upper side wall of the clamping plate 20, thereby locking the clamping assembly 2.
[0032] Since the contact surface 140 has a certain area, it can ensure the stability between the two when it comes into contact with the clamping plate 20.
[0033] In some further embodiments, the rotating shaft 13 is provided with a sliding plane 130, the abutment 14 is slidably engaged with the sliding plane 130, the abutment 14 is provided with a long groove 16, and a screw 17 is provided in the long groove 16. The screw 17 passes through the long groove 16 and is screwed onto the sliding plane 130.
[0034] Due to different actual conditions, the thickness of the clamped wires in each clamping cavity 7 is also different. Therefore, the abutment 14 and the rotating shaft 13 are specially arranged to slide. When there are fewer clamped wires, the end of the abutment 14 that is set on the abutment plane 140 can slide downward relative to the rotating shaft 13. When there are more clamped wires, the end of the abutment 14 that is set on the abutment plane 140 can slide upward relative to the rotating shaft 13.
[0035] Specifically, an elongated groove 16 is provided on the abutment 14, and a screw 17 is provided in the elongated groove 16. When the abutment 14 is moved, the screw 17 can be loosened. When it is moved into place, the screw 17 can be tightened to lock the abutment 14 and the rotating shaft 13.
[0036] In some further embodiments, the bottom of the sliding rod 11 is screwed with two first nuts 6, and a clamping plate 20 located at the bottom of the clamping assembly 2 is located between the two first nuts 6; the top of the sliding rod 11 is screwed with two second nuts 12, and a support plate 10 is located between the two second nuts 12.
[0037] Adjusting the two first nuts 6 can adjust the vertical position of the entire sliding rod 11 relative to the clamping plate 20, and adjusting the two second nuts 12 can adjust the vertical position of the support plate 10 relative to the sliding rod 11.
[0038] In some further embodiments, buffer pads 21 are provided on both the upper and lower walls of the clamping cavity 7.
[0039] The buffer pad 21 has a certain degree of elasticity, which can both pre-compress the line and prevent the line from being damaged by mechanical force.
[0040] In some further embodiments, a base 3 is also included, which is connected to the end of the clamping assembly 2 away from the locking assembly 1.
[0041] The base 3 is located at the lower end of the clamping assembly 2. Generally, the clamping plate 20 and the base 3 are connected to each other. In other embodiments, the two can be connected by screws or welding.
[0042] One end of the rotating shaft 13 is provided with a rotating rod 4 to facilitate the rotation of the rotating shaft 13.
[0043] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
