Description

Technical Field

[0001] This utility model relates to the field of cable support technology, and in particular to the support structure for electrical conduits in power distribution rooms. Background Technology

[0002] A power distribution room, simply put, is a room for distributing electrical energy. It serves to protect, meter, and distribute electrical energy, with voltage levels below 35kV. Inside, it houses switches, transformers, capacitors, and related protection and measuring devices. The electrical wires in the distribution room are wrapped and laid in conduits, typically in cable trenches. Cable trenches are underground pipes used for laying and replacing power or telecommunications cables, and also serve as the enclosure structure for the laid cables. These trenches come in rectangular, circular, and arched shapes. Cable supports are installed within the trenches. These supports are usually made of metal and are fixed to the trench walls through pre-embedding, welding, or screws. The cables are supported by the supports, maintaining a certain distance from the trench bottom. Commonly used supports include angle steel supports and prefabricated supports. To ensure personal safety, the cable trench supports must be reliably grounded, with grounding wires laid along the entire length, and multiple grounding points should be provided as designed. The grounding wire can be made of φ10 round steel, laid along the entire length of the support and reliably welded to the support. Alternatively, the angle steel of the cable trench edge protection or the pre-embedded flat steel can be used as the grounding wire. In this case, it is no longer necessary to lay a dedicated grounding wire.

[0003] In the existing technology, the angle steel brackets installed in cable trenches mainly consist of a vertically fixed angle steel with multiple horizontally fixed support angle steels distributed along its vertical direction to support the cables in layers. However, the cables are not fixed in place. Self-locking cable ties are usually used to bind and fix the cables. However, this simple method is not reliable in fixing the cables, and it is even impossible to effectively stabilize the cables on the horizontal support angle steel. This can easily lead to the cables not being guided and fixed in an orderly manner, or even falling off the horizontal support angle steel, making them difficult to manage.

[0004] Therefore, based on the above-mentioned technical problems, those skilled in the art urgently need to develop a support structure for electrical conduits in power distribution rooms. Utility Model Content

[0005] The purpose of this utility model is to provide a power distribution room electrical conduit support structure that can stably support and fix the electrical conduits in a power distribution room.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The present invention relates to a power distribution room wiring conduit support structure, including a cable trench, wherein support structures are provided on both sides of the cable trench, and the support structures are continuously arranged along the extension direction of the cable trench. Each set of support structures includes: vertical angle steel and horizontal support angle steel. The vertical angle steel has a first vertical waist plate and a second vertical waist plate that are perpendicular to each other to form an angle steel structure. The horizontal support angle steel has a first horizontal waist plate and a second horizontal waist plate that are perpendicular to each other to form an angle steel structure.

[0008] The first vertical waist plate is fixed to the inner wall of the cable trench, and the second vertical waist plate is perpendicular to the inner wall of the cable trench. The inner side of the vertical angle steel is vertically connected to the second vertical waist plate with a first support column. The end of the first support column has an external thread. There are multiple first support columns, which are evenly distributed vertically on the vertical angle steel.

[0009] The horizontal support angle steel is horizontally set and connected to the vertical angle steel. The first horizontal waist plate is horizontally set and the second horizontal waist plate is located below the first horizontal waist plate. One end of the second horizontal waist plate is attached to the second vertical waist plate and has a first assembly hole for the first support column to pass through. The first assembly hole is set in two sets vertically, and the distance between the two sets of first assembly holes is equal to the distribution distance of the multiple first support columns.

[0010] A cable fixing structure is provided on the horizontal support angle steel to press and fix the cable on the horizontal support angle steel.

[0011] Furthermore, the vertical angle steel is fixed to one side of the inner wall of the cable trench by pre-embedding a rod inside the cable trench.

[0012] Furthermore, an upwardly curved limiting plate is connected to one end of the first horizontal waist plate opposite to the first vertical waist plate.

[0013] Furthermore, the cable fixing structure includes a horizontal pressure plate, with vertically connected downward connecting plates at both ends of the horizontal pressure plate, and a detachable connection structure is provided between the connecting plates and the second horizontal waist plate.

[0014] Furthermore, the detachable connection structure includes a second support column. Two second support columns are vertically connected to two ends of the second horizontal waist plate located outside the horizontal support angle steel. The ends of the second support columns have external threads. The two second support columns are arranged longitudinally. The spacing between the second support columns at the two ends of the second horizontal waist plate corresponds to the spacing between the connecting plates at both ends of the horizontal pressure plate.

[0015] Two sets of second assembly holes are provided at the lower end of the connecting plate so that the two second support columns at the same end position of the second horizontal waist plate can pass through one by one.

[0016] Furthermore, a rubber pad is provided on the lower surface of the horizontal pressure plate, and multiple arc-shaped notches are continuously opened on the lower surface of the rubber pad.

[0017] The electrical conduit support structure for power distribution rooms provided by this utility model has the following beneficial effects:

[0018] The height of the horizontal support angle steel on the vertical angle steel can be adjusted to adjust the support height of the electrical conduit. At the same time, the cable fixing structure is used to press and fix the cable to the horizontal support angle steel to guide and fix the cable in an orderly manner, preventing it from falling off the horizontal support angle steel. This facilitates the organization, fixing and support of the electrical conduit in the power distribution room. Attached Figure Description

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] Please see Figure 1-4 The electrical conduit support structure for the power distribution room includes a cable trench 1. Support structures are installed on both sides of the cable trench 1 to support the electrical conduit in the power distribution room. The support structures are continuously installed along the extension direction of the cable trench 1 to continuously support the electrical conduit in the power distribution room along the extension direction of the cable trench 1. Each set of support structures includes: a vertical angle steel 20 and a horizontal support angle steel 30. The vertical angle steel 20 and the horizontal support angle steel 30 are arranged perpendicularly to each other so that the vertical angle steel 20 is fixed to the inner wall of the cable trench 1 to support the horizontal support angle steel 30 to keep it horizontal, and then the horizontal support angle steel 30 supports the electrical conduit. The vertical angle steel 20 has a first vertical waist plate 21 and a second vertical waist plate 22 that are perpendicular to each other to form an angle steel structure. The horizontal support angle steel 30 has a first horizontal waist plate 31 and a second horizontal waist plate 32 that are perpendicular to each other to form an angle steel structure.

[0031] The first vertical waist plate 21 is fixed to the inner wall of the cable trench 1, and the second vertical waist plate 22 is perpendicular to the inner wall of the cable trench 1. The inner side of the vertical angle steel 20 is located on the second vertical waist plate 22 and is vertically connected to the first support column 23. The end of the first support column 23 has an external thread. There are multiple first support columns 23 and they are evenly distributed vertically on the vertical angle steel 20.

[0032] A horizontal support angle steel 30 is horizontally positioned and connected to a vertical angle steel 20. A first horizontal waist plate 31 is horizontally positioned, with a second horizontal waist plate 32 located below it. One end of the second horizontal waist plate 32 is attached to the second vertical waist plate 22 and has a first assembly hole 33 through which a first support column 23 passes. There are two sets of vertically positioned first assembly holes 33, with the distance between the two sets equal to the distribution spacing of the multiple first support columns 23. Therefore, when assembling and connecting the vertical angle steel 20 and the horizontal support angle steel 30, The horizontal support angle steel 30 is aligned with the first support column 23 at a suitable height, and the first support column 23 passes through the first assembly hole 33. Then, it is threadedly connected to the first support column 23 with external threads by a nut to tighten and fix the second horizontal waist plate 32. When the first support column 23 passes through the first assembly hole 33, the first horizontal waist plate 31 and the second horizontal waist plate 32 of the horizontal support angle steel 30 both abut against the first vertical waist plate 21 to cooperate with the first support column 23 to stably support the horizontal support angle steel 30, so that the horizontal support angle steel 30 has the support strength to support the cable.

[0033] A cable fixing structure is installed on the horizontal support angle steel 30 to press and fix the cable to the horizontal support angle steel 30. This avoids the need to use self-locking cable ties or other tools to bind the cable during the cable laying process. These tools are not only unstable, but also fail to properly fix the cable to the horizontal support angle steel 30. The cable fixing structure is easy and quick to assemble, can stably fix the laid cable to the horizontal support angle steel 30, and is easy to disassemble and reinstall during later maintenance, thus improving maintenance efficiency.

[0034] Furthermore, the vertical angle steel 20 is fixed to the inner wall of the cable trench 1 by pre-embedding a pre-embedded rod 24 in the side wall of the cable trench 1 to stabilize and fix the vertical angle steel 20, thereby maintaining stable support for the horizontal support angle steel 30.

[0035] Furthermore, an upwardly curved limiting plate 34 is connected to one end of the first horizontal waist plate 31 opposite to the first vertical waist plate 21, so that the cable is blocked by the limiting plate 34 during the cable laying process, preventing the cable from falling off the horizontal support angle steel 30.

[0036] Furthermore, the cable fixing structure includes a horizontal pressure plate 41, with downwardly extending connecting plates 42 vertically connected to both ends of the horizontal pressure plate 41. A detachable connection structure is provided between the connecting plates 42 and the second horizontal waist plate 32. The connecting plates 42 and the second horizontal waist plate 32 are fixedly connected through the detachable connection structure to fix the position of the horizontal pressure plate 41. The horizontal pressure plate 41 is used to press and fix the cable on the horizontal support angle steel 30. The connecting plates 42 on both sides cover the cable to prevent it from falling off the horizontal support angle steel 30, thus having the function of gathering the cable.

[0037] Furthermore, the detachable connection structure includes a second support column 35. Two second support columns 35 are vertically connected to two ends of the second horizontal waist plate 32 located outside the horizontal support angle steel 30. The ends of the second support columns 35 have external threads. The two second support columns 35 are arranged longitudinally. The spacing between the second support columns 35 at the two ends of the second horizontal waist plate 32 corresponds to the spacing between the connecting plates 42 at both ends of the horizontal pressure plate 41.

[0038] Two sets of second assembly holes 43 are provided at the lower end of the connecting plate 42 so that two second support columns 35 at the same end position on the second horizontal waist plate 32 can pass through one-to-one.

[0039] Specifically, during installation, the connecting plates 42 on both sides of the cable fixing structure are positioned across the cable, and the horizontal pressure plate 41 is placed horizontally above the cable. The structure is then moved until the second support column 35 is inserted into the second assembly hole 43. The connecting plates 42 are then secured to the second horizontal waist plate 32 by the threaded engagement of the nut and the externally threaded second support column 35. Therefore, the support height of the connecting plates 42 on the horizontal pressure plate 41 after connection should be appropriate for the cable diameter to ensure stable cable fixation and prevent excessive cable sway.

[0040] Furthermore, a rubber pad 44 is provided on the lower surface of the horizontal pressure plate 41. The lower surface of the rubber pad 44 has multiple arc-shaped notches 45. In order to better protect the cable and avoid damage to the outer layer of the cable caused by rigid contact, the rubber pad 44 contacts the top of the cable, and its elasticity can prevent the cable from being clamped too tightly and causing damage. The multiple arc-shaped notches 45 are adapted to the fixing of multiple cables when they are laid side by side, so that the arc-shaped notches 45 can be pressed and fixed according to the shape of the cable.

[0041] In summary, the height of the horizontal support angle steel on the vertical angle steel can be adjusted to adjust the electrical conduit to an appropriate support height. At the same time, the cable fixing structure is used to press and fix the cable to the horizontal support angle steel, so as to guide and fix the cable in an orderly manner and prevent it from falling off the horizontal support angle steel, thus facilitating the organization, fixing and support of the electrical conduit in the power distribution room.

[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
