Description

Technical Field

[0001] This utility model relates to the field of cable routing technology, and in particular to a cable connection device for prefabricated substations. Background Technology

[0002] A prefabricated substation, also known as a prefabricated transformer substation, is a combination of high-voltage switchgear, distribution transformer, and low-voltage power distribution equipment. It organically integrates the functions of transformer voltage reduction and low-voltage power distribution. Prefabricated substations are suitable for mines, factories, oil and gas fields, and wind power stations. They replace the original civil engineering power distribution rooms and substations, becoming a new type of complete set of power distribution equipment.

[0003] In the existing technology, during the actual cable assembly process inside the prefabricated substation, since the prefabricated substation integrates multiple sets of electrical equipment, and most of the electrical equipment has multiple sets of wiring ports, the number of cables that need to be wired inside the prefabricated substation is large and the cable length is long.

[0004] In existing technologies, cables often lack a bundle structure during assembly, making them prone to intertwining and tangling. This not only increases the difficulty of assembly but may also lead to safety hazards such as cable damage or short circuits. Furthermore, traditional cable assembly methods are cumbersome and affect assembly efficiency. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a cable connection device for prefabricated substations, so as to solve the technical problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A cable connection device for a box-type substation includes a substation box, an electrical equipment mounting bracket is provided at the top of the interior of the substation box, sliding grooves are provided on both sides of the electrical equipment mounting bracket, and a sliding rail is fixedly provided inside the substation box at a position corresponding to the sliding groove, and the sliding rail is slidably disposed inside the sliding groove.

[0008] The bottom of the electrical equipment mounting bracket has a through groove, and a positioning plate is set at the center of the through groove. The bottom of the electrical equipment mounting bracket has a guide plate, and the side wall of the guide plate is rotatably equipped with several evenly distributed support rods. The outer peripheral walls of two adjacent support rods are jointly equipped with a control line structure.

[0009] Furthermore, the electrical equipment mounting bracket is equipped with electrical appliances, and the wiring ports of the electrical appliances correspond to the positions of the through slots.

[0010] Furthermore, the control structure includes a wire support, one side of which has a rotating hole and the other side has an arc-shaped groove that slides with the support rod. The wire support has a wire groove inside, the rotating hole has a rotating tube inside, the outer peripheral wall of the rotating tube has a baffle fixedly installed, and the axis of the rotating tube has a sliding hole that slides with the support rod.

[0011] Furthermore, the baffle is internally threaded with a clamping rod, and an anti-slip plate is provided at the end of the clamping rod facing the wire groove.

[0012] Furthermore, the substation enclosure has several evenly distributed wire holes on its side wall, and a support plate is provided on the outer wall of the substation enclosure at the edge of the wire holes. A shrink ring fixedly connected to the support plate is provided inside the wire holes.

[0013] Furthermore, the axis of the wire hole is perpendicular to the support rod, and the center of the wire hole corresponds to the center of the gap between two adjacent support rods.

[0014] In summary, this utility model has at least one of the following beneficial technical effects:

[0015] 1. A cable connection device for a prefabricated substation, through multiple sets of support rods and control structures, can effectively fix the routing direction and trajectory of the conductors. Since the control structure is slidably connected to the support rods, and multiple sets of control structures can be set on the outer periphery of the same support rod, multiple sets of conductors can exist within the trajectory formed by the same support rod. Thus, when the electrical equipment has multiple sets of connection ports, the wiring can be arranged, which can effectively improve the neatness of the conductors inside the substation box when a large number of connections are made.

[0016] 2. In this cable connection device for a prefabricated substation, during the installation of the control structure, a support rod is inserted into a sliding hole, and another support rod, which is horizontally or vertically aligned with this support rod, corresponds to the position of the arc-shaped groove, such as... Figure 4 As shown, to achieve the purpose of installing the wire bracket, rotate the baffle to expose the opening of the wire groove. Then insert the wire into the inside of the wire groove, and rotate the baffle again to align the baffle with the wire bracket, thereby sealing the wire groove. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Example:

[0027] Reference Figure 1 - Figure 6 The present invention discloses a cable connection device for a box-type substation, including a substation box 1, an electrical equipment mounting bracket 2 is provided at the top of the interior of the substation box 1, sliding grooves 3 are provided on both sides of the electrical equipment mounting bracket 2, and a sliding rail 4 is fixedly provided at the position corresponding to the sliding groove 3 inside the substation box 1, and the sliding rail 4 is slidably disposed inside the sliding groove 3.

[0028] The bottom end of the electrical equipment mounting bracket 2 is provided with a through groove 5, and a positioning plate 6 is provided at the center of the through groove 5. The bottom end of the electrical equipment mounting bracket 2 is provided with a guide plate 7. Several evenly distributed support rods 8 are rotatably provided on the side wall of the guide plate 7, and the outer peripheral walls of two adjacent support rods 8 are jointly provided with a control line structure 9.

[0029] In this embodiment, during use, the electrical equipment mounting bracket 2 is pulled out to the outside of the substation enclosure 1 through the cooperation of the sliding groove 3 and the sliding rail 4. The electrical equipment is then installed inside the mounting bracket 2. The mounting bracket 2 is then pushed into the computer compartment of the substation enclosure 1. The wires to be connected are then inserted into the substation enclosure 1. The support rod 8 is used to guide the wires. Figure 4 As shown, after the wire routing is completed, the wire is connected to the electrical equipment, and then the wire is fixedly connected to the support rod 8 through the wire control structure 9 to fix the wire routing direction and routing trajectory.

[0030] Furthermore, by setting up multiple sets of support rods 8, multiple sets of wires can exist within the same trajectory, such as... Figure 2 As shown, when electrical equipment has multiple sets of wiring ports, arranging the wiring can effectively improve the neatness of the wires inside the substation box 1 when a large number of wirings are connected.

[0031] In a further preferred embodiment of this utility model, such as Figure 1-6 As shown, an electrical appliance 10 is installed inside the electrical equipment mounting bracket 2, and the wiring port of the electrical appliance 10 corresponds to the position of the through slot 5.

[0032] In this embodiment, the positioning plate 6 is used to support the electrical appliance 10, so as to provide support for the electrical appliance 10.

[0033] In a further preferred embodiment of this utility model, such as Figure 1-6 As shown, the control structure 9 includes a wire support 901. One side of the wire support 901 has a rotating hole 902, and the other side has an arc-shaped groove 903 that slides with the support rod 8. The wire support 901 has a wire groove 904 inside. The rotating hole 902 has a rotating tube 905 inside. The outer peripheral wall of the rotating tube 905 is fixedly provided with a baffle 906, and the axis of the rotating tube 905 has a sliding hole 907 that slides with the support rod 8.

[0034] In this embodiment, when installing the control wire structure 9, the support rod 8 is inserted into the sliding hole, and another support rod 8, which is horizontally or vertically aligned with this support rod 8, corresponds to the position of the arc-shaped groove 903. Figure 4As shown, to achieve the purpose of installing the wire bracket 901, rotate the baffle 906 to expose the opening of the wire groove 904. Then insert the wire into the wire groove 904 and rotate the baffle 906 again to align the baffle 906 with the wire bracket 901, thereby sealing the wire groove 904.

[0035] In a further preferred embodiment of this utility model, such as Figure 1-6 As shown, the baffle 906 is internally threaded with a clamping rod 908, and an anti-slip plate 909 is provided at one end of the clamping rod 908 facing the wire groove 904.

[0036] In this embodiment, by setting the clamping rod 908, when the wire is inserted into the wire groove 904, the clamping rod 908 is rotated to make the anti-slip plate 909 contact the wire, so as to fix the wire and prevent the wire from sliding.

[0037] In a further preferred embodiment of this utility model, such as Figure 1-6 As shown, the substation enclosure 1 has several evenly distributed wire holes 11 on its side wall. A support plate 12 is provided on the outer wall of the substation enclosure 1 at the edge of the wire holes 11. A shrink ring 13 is fixedly connected to the support plate 12 inside the wire holes 11.

[0038] In this embodiment, the wire hole 11 is used to insert the wire into the interior of the substation box 1, and the support plate 12 is used to install the shrink ring 13. The shrink ring 13 is made of rubber and is elastic, so that when the wire is inserted into the shrink ring 13, the shrink ring 13 is supported and the shrink ring 13 is pressed tightly against the outer wall of the wire, so as to seal the wire hole 11. When no wire is inserted, the shrink ring 13 is in a contracted state to seal the wire hole 11.

[0039] In a further preferred embodiment of this utility model, such as Figure 1-6 As shown, the axis of the wire hole 11 is perpendicular to the support rod 8, and the wire hole 11 is located at the center between two adjacent support rods 8.

[0040] In this embodiment, since the center of the wire hole 11 corresponds to the center of the gap between two adjacent support rods 8, when the wire is inserted through the wire hole 11, it can be directly inserted between the support rods 8, so that the wires form a straight line after the connection is completed. Figure 4 As shown, this is to avoid continuous bending of the wire, which would affect the service life of the wire.

[0041] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
