[0002] The cable of transformer substation is an important part of power system, and its main function is to transmit electric energy from power plant, transformer substation or other power supply station to each terminal user. The cable trench is an underground pipeline for laying and replacing power or communication cable facilities, and is used for protecting the cable from the influence of external environment. The cable support is a device for supporting and fixing the cable, which is usually made of metal or composite material and has high strength and corrosion resistance.

[0003] Therefore, the cable is laid in the cable trench through the cable support for wiring and protection, so as to facilitate installation and adjustment. For example, the prior art Chinese patent No. CN212085726U discloses an adjustable cable support, which comprises a "C" type steel and a cable support plate.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0022] Referring to Figures 1-5 Adjustable transformer substation equipment mounting bracket, including stand 1, the recessed portion in the side of stand 1 is evenly distributed with a plurality of support arms 2, locking assembly 3 is arranged between support arm 2 and stand 1, and the unfolding and storage of support arm 2 are fixed by locking assembly 3.

[0023] Among them, the top of support arm 2 is detachably connected with wire arranging piece 5 through fixed structure 4, and wire arranging piece 5 is used for arranging and fixing cable.

[0024] Further, the stand 1 is in U-shaped structure, which is fixedly connected to the side wall of the cable trench, wherein the distance between the two adjacent support arms 2 is greater than the length of the support arm 2, and the support arm 2 is folded and accommodated in the recessed portion of the stand 1.

[0025] In some embodiments, the bracket includes a column 1 and several support arms 2. Locking bolts are provided at the upper and lower ends of the column 1. The locking bolts are threadedly connected to nuts pre-embedded in the side wall of the cable trench to fix the column 1. After the support arms 2 are unfolded and fixed by the locking assembly 3, they are used to cooperate with the cable laying component 5 to lay and fix the cable.

[0026] Specifically, the distance between the adjacent two support arms 2 is greater than the length of the support arm 2, so as to prevent the support arm 2 from getting stuck when folded.

[0027] Furthermore, the locking assembly 3 includes a rod 31, one end of which is provided with a pressing part 311, and the other end of which passes through the column 1 and the support arm 2 and is threadedly connected to a stop member 312. The rod 31 is slidably connected to the column 1 and the support arm 2 through a compression spring 32 and a limiting member 33.

[0028] More specifically, both the column 1 and the support arm 2 are provided with a first limiting groove 34 at the through hole in the side wall, and the support arm 2 is also provided with a second limiting groove 35 at the through hole in the side wall. The limiting member 33 is embedded in the periphery of the end of the insertion rod 31, and the limiting member 33 is slidably connected with the first limiting groove 34 and the second limiting groove 35.

[0029] In this embodiment, the abutment 312 can be a nut, which is threaded to the end of the insertion rod 31 away from the pressing part 311. The abutment 312 abuts against the side wall of the column 1 to prevent the insertion rod 31 from slipping. Specifically, the insertion rod 31 can be pulled out by unlocking the abutment 312, and the insertion rod 31 and the compression spring 32 can be disassembled and replaced.

[0030] It should be added that, such as Figure 2 As shown, the compression spring 32 is sleeved around the insertion rod 31 and the limiting member 33, and the two ends of the compression spring 32 abut against the pressing part 311 and the side wall of the column 1 respectively. The compression spring 32 is used to reset the insertion rod 31, and the limiting member 33 is used to circumferentially lock the insertion rod 31.

[0031] The limiting member 33 is initially positioned within a pair of first limiting grooves 34 to support and fix the support arm 2. The limiting member 33 and the pressing part 311 are spaced apart and form a smooth section. After the pressing rod 31 causes the limiting member 33 to disengage from the first limiting grooves 34, the smooth section of the rod 31 disengages and is placed between the support arm 2 and the column 1, allowing the support arm 2 to rotate half a revolution.

[0032] Specifically, such as Figure 4As shown, after the support arm 2 rotates half a circle, the second limiting groove 35 corresponds to the first limiting groove 34 on the side wall of the column 1. The insertion rod 31 is reset under the action of the compression spring 32. The limiting member 33 is placed between the first limiting groove 34 and the second limiting groove 35, and the support arm 2 is fixed again, thus realizing the folding and fixing function.

[0033] In general, the cable tray 5 has a plate-like structure and is located on the top of the support arm 2. The top of the cable tray 5 is evenly distributed with several cable tray grooves 51. The cable trays 51 connect to the top of the cable tray 5 to form an opening. The two ends of the opening extend inward to form a stop part 52. The cable slides against the stop part 52 and is engaged in the cable tray 51.

[0034] Finally, the fixing structure 4 includes a pair of elastic claws 41, which are disposed opposite to each other on the bottom sides of the ribbon cable 5. The top of the support arm 2 extends downward to form a pair of slots 42, and the pair of elastic claws 41 are engaged in the slots 42 by abutting deformation.

[0035] In this embodiment, both the cable tray 5 and the elastic claw 41 are preferably made of materials with deformation capabilities such as rubber and plastic. The cable tray 51 and the two side stops 52 form a circular structure. The cable is limited in the cable tray 51 by the two side stops 52, which on the one hand avoids cable stacking, and on the other hand facilitates cable laying.

[0036] Specifically, a flip cover can be rotatably connected to one end of the top of the cable tray 5. The flip cover is fixed to the other end of the cable tray 5 by a snap-fit ​​mechanism to further prevent the cable from coming off the cable tray 51.

[0037] Furthermore, the free end of the elastic claw 41 is provided with a snap-fit ​​part. The snap-fit ​​part slides against the cable assembly 5 through the guide slope and is fixed to the support arm 2 through the slot 42. Similarly, by pushing a pair of elastic claws 41 at the same time to deform them under force and disengage them from the slot 42, the cable assembly 5 can be disassembled.

[0038] To elaborate further, the cross-section of support arm 2 has a U-shaped structure.

[0039] Working method: During operation, multiple columns 1 are fixedly connected to the inner wall of the cable trench at a certain interval by locking bolts. Then, the pressing part 311 drives the insertion rod 31 to move towards the force side. When the limiting part 33 is disengaged from the first limiting groove 34 and the second limiting groove 35, the support arm 2 can be rotated half a turn.

[0040] When the first limiting groove 34 of the support arm 2 corresponds to the first limiting groove 34 of the column 1, the insertion rod 31 is reset under the action of the compression spring 32, and the limiting member 33 is engaged in a pair of first limiting grooves 34 to fix the support arm 2.

[0041] Then, the cable slides against the two side stops 52 and is placed in the cable tray 51 to fix the cable.

[0042] Finally, by simultaneously pushing and pressing a pair of elastic claws 41 to deform them under force and disengage them from the slot 42, the ribbon cable 5 can be disassembled.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
