Description

Technical Field

[0001] The utility model relates to the technical field of cable retraction and extension, in particular to a cable retraction and extension device for a transformer substation machine room. Background Art

[0002] A substation is a place in the power system where voltage and current are transformed, electric energy is received and distributed. The outer end of the cable extends outward to connect to the substation, and the inner end of the cable is connected to the machine room, thus forming a closed circuit to realize power supply to users.

[0003] At present, a retracting and releasing device is required for retracting and releasing the cable. In order to make the cable be evenly wound when reeling, the existing retracting and releasing device generally allows the cable to pass through a fixed block, and the fixed block can move back and forth to achieve even winding.

[0004] However, the applicant found that when the cable passes through the hole of the fixing block, it is easy to cause friction between the cable and the front and rear ends of the hole, causing the cable sheath to wear. For this reason, we propose a cable retracting device for a substation room. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] As mentioned in the background art, when the cable passes through the hole of the fixing block in the prior art, it is easy to cause friction between the cable and the front and rear ends of the hole, causing the cable outer skin to be worn. The utility model provides a cable retracting device for a substation room.

[0023] Example 1

[0024] Reference Figures 1 to 4 A cable retracting device for a substation room includes a bracket 1, a retracting roller 2 is provided on the bracket 1 for retracting the cable, an electric guide rail 3 is provided on the front side of the retracting roller 2 of the bracket 1, and a fixing block 4 is provided on the output end of the electric guide rail 3, and a through hole 5 for the cable to pass through is provided on the fixing block 4, and the electric guide rail 3 drives the fixing block 4 to move horizontally, so that the through hole 5 drives the cable to move, so as to facilitate uniform winding;

[0025] The inner wall of the through hole 5 is evenly and circumferentially provided with an electric telescopic rod 7, and an installation component is provided on the output end of the electric telescopic rod 7, and an installation block 8 is provided on the installation component. The end of the installation block 8 away from the electric telescopic rod 7 is movably connected with a universal ball 9. The electric telescopic rod 7 drives the installation component to move, so that the installation block 8 drives the universal ball 9 to move, and then the universal balls 9 around are all in contact with the cable, so as to guide cables of different thicknesses. In this way, when the cable is retracted and released, it can contact each universal ball 9, so that the universal ball 9 rolls on the installation block 8, so that the universal ball 9 rolls and generates rolling friction with the cable. Compared with the method of generating sliding friction on the front and back sides of the through hole 5, the degree of wear can be greatly reduced, and the cable can be better protected. The back and forth movement of the through hole 5 drives the cable to move, and also causes the through hole 5 to collide with the cable. The use of the universal ball 9 arranged circumferentially to drive the cable to move prevents the cable from hitting the inner wall of the through hole 5, further protecting the cable.

[0026] The mounting assembly includes a mounting plate 10 connected to the output end of the electric telescopic rod 7, a limit rod 11 passes through the mounting plate 10, and a handle 12 is provided on the limit rod 11, and a return spring 13 connected to the mounting plate 10 is provided on the handle 12, a convex plate 14 is provided at the bottom of the mounting block 8, and the limit rod 11 passes through the convex plate 14, a plug-in plate 15 is provided on the mounting block 8, and the plug-in plate 15 is plugged into the mounting plate 10. In order to connect the plug-in plate 15 so that the plug-in plate 15 has a U-shaped structure, a slot 16 plugged into the plug-in plate 15 is opened on the mounting plate 10.

[0027] First, pull the handle 12 to move the limit rod 11 to stretch the reset spring 13, and then insert the plug plate 15 into the slot 16 to position the mounting block 8. At this time, the convex plate 14 is aligned with the limit rod 11, and the handle 12 can be released to allow the reset spring 13 to drive the limit rod 11 to reset and penetrate the convex plate 14, thereby limiting the convex plate 14, thereby fixing the mounting block 8, so that the mounting plate 10 can drive the mounting block 8 to move, and disassembly and assembly are more labor-saving.
