[0002] A high-voltage distribution cabinet is a device used in power systems to switch on and off, control or protect circuits. When connecting cables to a high-voltage distribution cabinet, the cables need to be fixed inside the cabinet to prevent the cables from being pulled and causing unstable connections with electrical components.

[0003] At present, the high-voltage distribution cabinet is relatively large and is equipped with many wires that need to be used. However, the existing distribution cabinet generally does not have the function of fixing the wires, resulting in the wires inside the distribution cabinet being arranged in a disorderly manner. The intertwined and entangled wires will not only increase the heat between the wires and accelerate the aging of the wires, but also increase the time for maintenance personnel to find the wires when a problem occurs in a certain wire and needs maintenance, delaying the best time for emergency repairs, and even causing large economic losses.

[0004] For this purpose, a cable fixing device for a high-voltage distribution cabinet is proposed. Utility Model Content

[0025] like Figures 1 to 5As shown, a cable fixing device for a high-voltage power distribution cabinet comprises a power distribution cabinet body 1 and a wire 2, wherein a front positioning column 3 for limiting and fixing the front side of the wire 2 is fixedly installed inside the power distribution cabinet body 1, and an inverted "Z"-shaped moving cavity 4 is provided on the rear wall surface of the power distribution cabinet body 1, and a moving wheel 5 with a "concave"-shaped cross section is slidably connected inside the moving cavity 4, and one end of the moving wheel 5 is connected to a rear positioning column 6 through a bearing member, and the surface of the rear positioning column 6 is smooth, and a distance adjustment portion 8 for adjusting the clamping tightness of a single wire 2 is arranged on the rear positioning column 6, and a support portion 9 for ensuring the stability of the rear positioning column 6 when moving is installed on the movable end of the rear positioning column 6, and a pushing portion 7 for adjusting the height of the rear positioning column 6 is arranged on the power distribution cabinet body 1;

[0026] Specifically, by moving the moving wheel 5, the rear positioning column 6 can be driven to move along the laying direction of the moving cavity 4, changing the height of the rear positioning column 6 so as to move the rear positioning column 6 to a height corresponding to the front positioning column 3, so that the front positioning column 3 and the rear positioning column 6 can clamp and fix the wire 2 front and back to avoid multiple wires 2 being intertwined and entangled together, thereby reducing the heat generated between the wires 2, and each individual wire 2 can be fixed by the set distance adjusting part 8, so that the maintenance personnel can quickly find the wire 2 that needs to be repaired when replacing and repairing the wire 2, thereby avoiding delays in the emergency repair time, preventing the waste of time caused by searching for the wire 2, and avoiding greater economic losses.

[0027] like Figure 1 and Figure 2 As shown, the pushing portion 7 includes a telescopic column 701, four circumferentially distributed telescopic columns 701 are installed at the bottom of the rear positioning column 6, and the other ends of the four telescopic columns 701 are welded with protrusions 702. A through cavity 703 is opened on the side wall surface of the distribution cabinet body 1, and a rack 704 is slidably connected inside the through cavity 703. A gear 705 meshing with the rack 704 is installed on the outer wall surface of the distribution cabinet body 1;

[0028] Specifically, by rotating the gear 705, the rack 704 can be driven to move horizontally, so as to push the rear positioning column 6 to move along the laying direction of the movable cavity 4. At the same time, the telescopic column 701 can be telescoped accordingly to adapt to the height change of the rear positioning column 6, so that the rear positioning column 6 can be smoothly lifted to a height flush with the front positioning column 3, thereby achieving the purpose of clamping and fixing the wire 2 front and back.

[0029] like Figure 2 and Figure 3As shown, the distance adjusting part 8 includes a threaded through hole 801, and the rear wall surface of the power distribution cabinet body 1 and the rear positioning column 6 are both provided with threaded through holes 801 corresponding to the wire 2, and the two corresponding threaded through holes 801 at the front and rear are internally threadedly connected with a screw 802, and a clamping plate 803 is installed at one end of the screw 802 facing the wire 2;

[0030] Specifically, by rotating the screw 802, the distance between the clamping plate 803 and the front positioning column 3 can be changed, so that the distance between the front positioning column 3 and the clamping plate 803 can be adjusted to a suitable size for clamping and tightening the wire 2. At the same time, the screw 802 is rotated in the opposite direction to expand the distance between the front positioning column 3 and the clamping plate 803, so that a problematic wire 2 can be taken out. The structure is simple and can be operated without the need for professional personnel.

[0031] like Figure 2 As shown, a backing plate 804 is bonded to the side wall of the clamping plate 803, and a plurality of equally spaced balls 805 are rollingly connected to the side wall of the backing plate 804 away from the clamping plate 803;

[0032] Specifically, the ball 805 is arranged to roll when the rear positioning column 6 moves, thereby reducing the extrusion and wear on the surface of the wire 2 and ensuring the integrity of the wire 2; at the same time, the bonded pad 804 is convenient for replacement when it fails and wears out.

[0033] like Figure 5 As shown, the power distribution cabinet body 1 is provided with a support part 9 for ensuring the stability of the movable end of the rear positioning column 6 moving up and down, and the support part 9 includes two telescopic rods 903 welded to the movable end of the rear positioning column 6, and the other ends of the two telescopic rods 903 are threadedly connected with a "T"-shaped stabilizing block 902, and a sliding cavity 901 for the stabilizing block 902 to slide up and down is opened on the inner wall surface of the power distribution cabinet body 1;

[0034] Specifically, by setting the stabilizing block 902, it can move along the setting direction of the sliding cavity 901 when the rear positioning column 6 changes height, thereby enhancing the stability of the rear positioning column 6 when moving. During the movement, the telescopic rod 903 set can be telescoped accordingly, thereby adapting to the change in the distance between the movable end of the rear positioning column 6 and the inner wall of the distribution cabinet body 1.

[0035] like Figure 4 As shown, a semicircular clamping cavity 301 is provided on a wall surface of the front positioning column 3 facing the wire 2, and a protective pad is bonded to the inner wall surface of the clamping cavity 301;

[0036] Specifically, the clamping cavity 301 provided can effectively expand the limiting wrapping range of the wire 2 and improve the limiting effect of the wire 2. The bonded protective pad can protect the surface of the wire 2 and prevent the outer surface of the wire 2 from being scratched or even broken, thereby ensuring the safety of the wire 2 when in use.

[0037] In summary: by moving the moving wheel 5, the rear positioning column 6 can be driven to move along the laying direction of the moving cavity 4, and the height of the rear positioning column 6 can be changed, so that the rear positioning column 6 can be moved to a height corresponding to the front positioning column 3, so that the set front positioning column 3 and the rear positioning column 6 can clamp and fix the wire 2 front and back, avoiding the interweaving and entanglement of multiple wires 2, and reducing the heat generated between the wires 2. The set distance adjusting part 8 can fix each individual wire 2, so that the maintenance personnel can quickly find the wire 2 that needs to be repaired when replacing and repairing the wire 2, avoiding delays in the emergency repair time, preventing the waste of time caused by searching for the wire 2, and avoiding greater economic losses.
