[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] This utility model provides a load regulation device for transformer substations, such as... Figure 1-6 As shown, the load regulating device for the distribution area includes a load regulating device body 1, a cover plate 2 rotatably mounted on the front side of the load regulating device body 1, a wiring terminal 3 provided on the lower front side of the load regulating device body 1, a heat dissipation vent 4 provided on the lower end of the load regulating device body 1, a cable protection box 5 fixedly mounted on the lower side of the load regulating device body 1, a wire passage 6 opened in the front side of the cable protection box 5, the upper opening of the wire passage 6 is aligned with the wiring terminal 3, and an anti-derailment component is provided in the wire passage 6.
[0030] By setting up the anti-derailment component, it is ensured that when the wire connected to the load regulating device of the distribution area is pulled by an external force, the anti-derailment component can effectively prevent the wire from separating from the terminal 3.
[0031] The anti-derailment assembly includes a winding shaft 7, which is rotatably installed inside the cable protection box 5. Multiple sets of support plates 8 are fixedly installed inside the cable threading channel 6. The winding shaft 7 is movably inserted into the multiple sets of support plates 8. Multiple sets of winding wheels 9 are fixedly installed on the winding shaft 7. The multiple sets of winding wheels 9 are located on the left and right sides of the multiple sets of support plates 8 respectively. A locking seat 14 is fixedly installed on the left side of the cable protection box 5. Two sets of return springs 15 are sleeved between the right end of the locking seat 14 and the left side of the cable protection box 5. A locking rod 16 is slidably sleeved on the right end of the locking seat 14. A positioning hole 17 is opened inside the left end of the winding shaft 7.
[0032] The rotating winding shaft 7 drives multiple winding wheels 9 to rotate, and the multiple winding wheels 9 wind the wire, so that after the wire passes through the wire channel 6 and connects to the terminal 3, the part of the wire outside the cable protection box 5 will not separate from the terminal 3 when it is pulled. The locking seat 14, two sets of return springs 15, locking rod 16 and positioning hole 17 cooperate with each other to ensure that the winding shaft 7 and multiple winding wheels 9 rotate when the wire is pulled.
[0033] The outer walls of multiple sets of winding wheels 9 are provided with wire grooves 10, and the inner walls of multiple sets of wire grooves 10 are provided with protective pads.
[0034] By creating wire grooves 10 with protective pads on the outer walls of multiple sets of winding wheels 9, the protective pads can buffer and protect the wires when they are wound on the winding wheels 9, preventing the wires from being damaged by direct friction with the outer walls of the winding wheels 9. At the same time, the soft texture of the protective pads can increase the friction between the wires and the winding wheels 9, further improving the anti-loosening effect.
[0035] Clamping seats 11 are fixedly installed on the right side of each set of winding wheels 9. Adjusting bolts 12 are threadedly inserted into each set of clamping seats 11. Clamping blocks 13 are slidably installed inside each set of clamping seats 11. The sets of clamping seats 11 and clamping blocks 13 are rotatably connected.
[0036] When the wire is pulled, the clamping seat 11, adjusting bolt 12 and clamping block 13 work together to further fix and limit the wire wound on the winding wheel 9. The adjusting bolt 12 is threaded to the clamping seat 11 and can be adjusted according to the thickness of the wire to accommodate different specifications of wire. The clamping block 13 slides in the clamping seat 11 and clamps and fixes the wire, which can prevent the wire from coming off the winding wheel 9 when the wire is under tension.
[0037] The inner wall of the positioning hole 17 and the right end of the locking rod 16 are both hexagonal, and the right end of the locking rod 16 is adapted to the inner wall of the positioning hole 17.
[0038] When the right end of the locking rod 16 is inserted into the positioning hole 17, the winding shaft 7 is prevented from rotating. When it is necessary to adjust the rotation of the winding shaft 7, simply pull the locking rod 16 out of the positioning hole 17 to release the lock on the winding shaft 7. At this time, the winding shaft 7 can be rotated easily, thereby driving multiple sets of winding wheels 9 to rotate, realizing the winding or unwinding operation of the wire. This ensures the stability of the winding shaft 7 under normal working conditions and facilitates flexible adjustment when needed.
[0039] A heat dissipation cavity 18 is provided in the rear end of the cable protection box 5. A cooling fan 20 is fixedly installed in the heat dissipation cavity 18. The upper opening of the heat dissipation cavity 18 is in contact with the heat dissipation port 4 provided at the lower end of the load regulating device body 1.
[0040] By opening a heat dissipation cavity 18 at the rear end of the cable protection box 5 and installing a cooling fan 20, with the upper opening of the heat dissipation cavity 18 fitting snugly against the heat dissipation port 4, when the load regulating device body 1 generates heat during operation, the heat can be conducted to the heat dissipation cavity 18 through the heat dissipation port 4, and then absorbed and dissipated by the cooling fan 20 inside the heat dissipation cavity 18. This effectively improves the heat dissipation performance of the device, avoids affecting its performance and service life due to excessively high temperature inside the load regulating device body 1, and ensures the stability and reliability of the distribution area load regulating device during long-term operation.
[0041] Heat dissipation fins 19 are fixedly installed inside the heat dissipation cavity 18, and the heat dissipation fins 19 are attached to the heat dissipation fan 20.
[0042] By fixing and installing heat dissipation fins 19 that are in close contact with the cooling fan 20 inside the heat dissipation cavity 18, the heat dissipation fins 19 can play the role of assisting heat dissipation and supporting fixation. The heat dissipation fins 19 can increase the heat dissipation efficiency of the heat dissipation cavity 18 to the main body 1 of the load regulating device, improve the heat conduction efficiency, and enable heat to be transferred from the heat dissipation port 4 to the cooling fan 20 more quickly, and then dissipate it.
[0043] The right end of the winding shaft 7 is provided with an internal hexagonal groove that is the same as that of the positioning hole 17.
[0044] The design of the internal hexagonal slot greatly facilitates the installation, debugging, and subsequent maintenance of the winding shaft 7 component. With the help of appropriate internal hexagonal tools, workers can easily rotate, tighten, or disassemble the winding shaft 7 component, effectively improving work efficiency and reducing the complexity and time cost of operation.
[0045] Working principle:
[0046] When using this load regulating device, first pass the wire through the wire passage 6 and connect it to the terminal block 3. Then, insert an Allen wrench into the Allen groove on the right end of the winding shaft 7 and pull the locking rod 16, which is inserted into the positioning hole 17, to slide open on the right side of the locking seat 14. This allows the winding shaft 7 to rotate, driving multiple winding wheels 9 to rotate and winding the wire onto them. During this process, the sliding distance of the clamping block 13 in the clamping seat 11 can be adjusted by rotating the adjusting bolt 12 on the threaded position of the clamping seat 11 according to the thickness of the wire, thereby properly clamping and fixing the wire. After the wire is wound, under the recoil force of the two sets of springs 15, the locking rod 16 slides on the right side of the locking seat 14, inserting the right end of the locking rod 16 into the positioning hole 17 on the left end of the winding shaft 7. The hexagonal shape locks the winding shaft 7, preventing it from rotating. At this time, if the wire is pulled by an external force, the wire will be unable to move due to the hexagonal shape. The wire is wound around the winding wheel 9 and clamped and fixed by the clamping block 13. At the same time, the winding shaft 7 is locked by the locking rod 16 and cannot rotate. Therefore, it can effectively prevent the wire from separating from the terminal 3 and ensure the normal operation of the load regulating device. In addition, during the operation of the main body 1 of the load regulating device, the heat generated by it is conducted to the heat dissipation cavity 18 through the heat dissipation port 4. The heat dissipation fins 19 and the heat dissipation fan 20 in the heat dissipation cavity 18 work together to absorb and dissipate the heat, ensuring that the main body 1 of the load regulating device will not be affected by excessive temperature, thus extending its performance and service life.

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.
