Description

Technical Field

[0001] The utility model belongs to the technical field of wire harness clamping structures, and in particular relates to a wire harness clamping structure for a high-voltage power distribution cabinet. Background Art

[0002] High-voltage distribution cabinet is a high-voltage distribution device, which is used in power generation, transmission, distribution, power conversion and consumption in the power system, and plays the role of switching, control or protection. Its voltage level is usually between 3.6kV and 550kV. High-voltage distribution cabinet mainly includes high-voltage circuit breakers, high-voltage disconnectors and grounding switches, high-voltage load switches, high-voltage automatic reclosing and sectionalizers, high-voltage operating mechanisms, high-voltage explosion-proof distribution devices, etc. Since a large number of wire harnesses need to enter and exit the high-voltage distribution cabinet, in order to prevent the wire harnesses from being entangled, displaced, and loose, the wire harnesses need to be clamped and fixed. In the prior art, the wire harnesses are generally fixed by buckles, straps, fixed brackets, splints, etc., which are very inconvenient for fixing and disassembling the wire harnesses, and have poor flexibility in use. The wire harnesses are generally clamped and fixed tightly, lack redundant activity space, and are easily damaged by pulling. Utility Model Content

[0003] In view of the above problems, the purpose of the utility model is to provide a high-voltage distribution cabinet wire harness clamping structure, which can thoroughly scrape off the stubborn sludge adhered to the inner wall of the pipeline. The sludge pump is protected by a pump body anti-scratch protection chamber to prevent the dirt in the pipeline from scratching the sludge pump.

[0004] To achieve the above objectives, the utility model provides the following technical solutions: a high-voltage distribution cabinet harness clamping structure, comprising a distribution cabinet, an inner side wall of the distribution cabinet is provided with a screw-connected fixing frame, a side surface of the screw-connected fixing frame is provided with a socket, a buckle groove is provided inside the socket, the inside of the socket is inserted and connected with a clamping device, the clamping device comprises a socket inserted and connected with the socket, a buckle installation chamber is provided inside the socket, a spring is installed inside the buckle installation chamber, a buckle is slidably inserted inside the buckle installation chamber, a shift block is installed on the top of the buckle, one side of the socket is connected with a sliding mounting seat, a slide groove is provided inside the sliding mounting seat, two groups of clamping mechanisms are slidably installed inside the slide groove, and the two groups of clamping mechanisms are symmetrically arranged, the clamping mechanism comprises a slider slidably connected with the slide groove, a roller mounting frame is installed on one side of the slider, a limited clamping roller is rotatably installed inside the roller mounting frame, a bidirectional screw is rotatably installed inside the slide groove, and the bidirectional screw is threadedly connected to the slider.

[0005] The beneficial effects of the utility model are as follows: when the device is used, after the screw-connected fixing frame is fixed with the screw hole on the distribution cabinet by means of bolts, the socket on one side of the sliding mounting seat can be inserted into the socket hole. The number of sliding mounting seats installed on each set of screw-connected fixing frames is determined according to the number of wire harness strands that need to be fixed, and the number and position of the socket holes inserted with the sockets on each set of screw-connected fixing frames are consistent. During the insertion process, the buckle is squeezed into the buckle mounting chamber and the spring is compressed. When the socket is inserted into place, the buckle is aligned with the buckle groove, and under the action of the rebound force of the spring, the buckle bounces into the buckle groove, and the socket hole and the socket are fixed by the cooperation of the buckle and the buckle groove. When the socket needs to be removed, it is only necessary to toggle the dial block to drive the buckle to leave the buckle groove, and the sliding mounting seat together with the socket can be pulled off from the screw-connected fixing frame, making the installation and disassembly of the clamping device very convenient, and at the same time, the number of installations can be freely selected according to needs, which greatly improves the convenience and flexibility of use.

[0006] The wire harness is clamped between two sets of limit clamping rollers located on the same sliding mounting seat. Since the limit clamping rollers can rotate and their shape is thin in the middle and thick at both ends, with an arc transition between the middle end and the two ends, the limit clamping rollers can clamp the wire harness in its middle position to play a limiting role, and can be suitable for clamping cables of different thicknesses. While preventing the wire harness from slipping out to the side, the wire harness is not completely fixed, so that the wire harness can remain in a relatively loose state, and the wire harness has a certain amount of redundant activity space, which reduces the possibility of breakage caused by pulling during installation, maintenance, and movement and pulling due to vibration during use, thereby improving the safety of the distribution cabinet.

[0007] For quick installation and removal of screw-on mounting brackets:

[0008] As a further improvement of the above technical solution: the inner wall of the power distribution cabinet is provided with a screw hole, and the screw hole is connected to the screw fixing frame by bolts.

[0009] The beneficial effect of this improvement is that the power distribution cabinet and the screw-connected fixing frame are connected by bolts, and the screw-connected fixing frame can be quickly installed and disassembled.

[0010] To adjust the position of the slide mount:

[0011] As a further improvement of the above technical solution: one end of the bidirectional screw passes through the sliding mounting seat and is connected to the first knob.

[0012] The beneficial effect of this improvement is that the bidirectional screw can be driven to rotate by rotating the first knob to adjust the position of the sliding mounting seat.

[0013] In order to limit the clamping roller, the wire harness can be clamped in the middle position to play a limiting role:

[0014] As a further improvement of the above technical solution: the shape of the limit clamping roller is thin in the middle and thick at both ends, and there is an arc transition between the middle end and the two ends.

[0015] The beneficial effect of this improvement is that since the limit clamping roller can rotate and its shape is thin in the middle and thick at both ends, and there is an arc transition between the middle end and the two ends, the limit clamping roller can clamp the wire harness in its middle position to play a limiting role.

[0016] In order to enable the device to be equipped with more clamping devices:

[0017] As a further improvement of the above technical solution: the jacks are arranged in two layers, upper and lower, on each set of screw-connected fixing frames, and the upper and lower layers of jacks are arranged alternately, and a set of sockets are inserted into each jack.

[0018] The beneficial effect of this improvement is that the jacks are provided with an upper and lower layer on each set of screw-connected fixing frames, and the upper and lower layers of the jacks are staggered, so the clamping devices inserted into the upper and lower layers of the jacks are also staggered, while ensuring that the single-layer clamping device has sufficient installation and adjustment space, avoiding mutual influence between the upper and lower layers of the clamping devices, and allowing the device to install more clamping devices, and clamp more groups of wire harnesses at the same time.

[0019] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] When the device is used, after the screw-connected fixing frame 3 is fixed to the screw hole 2 on the distribution cabinet 1 by bolts, the socket 6 on one side of the sliding mounting seat 11 can be inserted into the socket 4. The number of sliding mounting seats 11 installed on each group of screw-connected fixing frames 3 is determined according to the number of wire harness strands to be fixed, and the number and position of the sockets 4 with the sockets 6 inserted on each group of screw-connected fixing frames 3 are consistent. During the insertion process, the buckle 9 is squeezed into the buckle installation chamber 7 and the spring 8 is compressed. When the socket 6 is inserted into place, the buckle 9 is aligned with the buckle groove 5. Under the action of the rebound force of the spring 8, the buckle 9 rebounds into the buckle groove 5. The socket 4 and the socket 6 are fixed by the cooperation of the buckle 9 and the buckle groove 5. When the socket 6 needs to be removed, it is only necessary to toggle the dial block 10 to drive the buckle 9 to leave the buckle groove 5, and the sliding mounting seat 11 together with the socket 6 can be pulled off from the screw-connected fixing frame 3, so that the installation and disassembly of the clamping device are very convenient, and the number of installations can be freely selected according to needs, which greatly improves the convenience and flexibility of use.

[0031] The wire harness is clamped between two sets of limit clamping rollers 15 located on the same sliding mounting seat 11. Since the limit clamping rollers 15 can rotate and their shape is thin in the middle and thick at both ends, with an arc transition between the middle end and the two ends, the limit clamping rollers 15 can clamp the wire harness in its middle position to play a limiting role, and can be suitable for clamping cables of different thicknesses. While preventing the wire harness from slipping out to the side, the wire harness is not completely fixed, so that the wire harness can remain in a relatively loose state, so that the wire harness has a certain amount of redundant activity space, reducing the possibility of breakage caused by pulling during installation, maintenance, and movement and pulling due to vibration during use, thereby improving the safety of the distribution cabinet.

[0032] The inner wall of the power distribution cabinet 1 is provided with a screw hole 2, and the screw hole 2 is connected to the screw fixing frame 3 by bolts.

[0033] The power distribution cabinet 1 and the screw-connected fixing frame 3 are connected by bolts, and can be quickly installed and disassembled.

[0034] One end of the bidirectional screw 16 passes through the sliding mounting seat 11 and is connected to the first knob 17 .

[0035] The bidirectional screw rod 16 can be driven to rotate by rotating the first knob 17 to adjust the position of the sliding mounting seat 11 .

[0036] The shape of the position-limiting clamping roller 15 is thin in the middle and thick at both ends, and there is an arc transition between the middle end and the two ends.

[0037] Since the limiting clamping roller 15 can rotate and has a shape of being thin in the middle and thick at both ends, with an arc transition between the middle end and the two ends, the limiting clamping roller 15 can clamp the wire harness at its middle position to play a limiting role.

[0038] The jacks 4 are provided in two layers, upper and lower, on each set of screw-connected fixing frames 3 , and the jacks 4 in the upper and lower layers are arranged alternately, and a set of sockets 6 is inserted into each jack 4 .

[0039] The jacks 4 are provided with two layers, upper and lower, on each set of screw-connected fixing frames 3, and the upper and lower layers of the jacks 4 are staggered, so the clamping devices inserted into the upper and lower layers of the jacks 4 are also staggered, while ensuring that the single-layer clamping device has sufficient installation and adjustment space, avoiding mutual influence between the upper and lower layers of the clamping devices, and allowing the device to install more clamping devices, and clamp more groups of wire harnesses at the same time.

[0040] Working principle and use process of the utility model: When the device is used, after the screw-connected fixing frame 3 is fixed to the screw hole 2 on the power distribution cabinet 1 by bolts, the socket 6 on one side of the sliding mounting seat 11 can be inserted into the socket 4. The number of sliding mounting seats 11 installed on each group of screw-connected fixing frames 3 is determined according to the number of wire harness strands to be fixed, and the number and position of the sockets 4 with the sockets 6 inserted on each group of screw-connected fixing frames 3 are consistent. During the insertion process, the buckle 9 is squeezed into the buckle installation chamber 7 and the spring 8 is compressed. When the socket 6 is inserted After being in place, the buckle 9 is aligned with the buckle groove 5, and under the action of the rebound force of the spring 8, the buckle 9 bounces into the buckle groove 5, and the jack 4 and the socket 6 are fixed by the cooperation of the buckle 9 and the buckle groove 5. When the socket 6 needs to be removed, it is only necessary to toggle the block 10 to drive the buckle 9 to leave the buckle groove 5, and the sliding mounting seat 11 together with the socket 6 can be pulled off from the screw fixing frame 3, making the installation and disassembly of the clamping device very convenient, and at the same time, the number of installations can be freely selected according to needs, which greatly improves the convenience and convenience of use. Flexibility. When clamping the wire harness, the wire harness is passed through each group of limit clamping rollers 15 located on the same vertical plane in turn, and then the first knob 17 is turned according to the thickness of the wire harness to drive the bidirectional screw 16 to rotate. The bidirectional screw 16 drives the two sliders 13 located in the same slide groove 12 to move toward each other through the spiral transmission between the slider 13, so that the wire harness is clamped between the two groups of limit clamping rollers 15 located on the same sliding mounting seat 11. Since the limit clamping roller 15 can rotate, and its shape is thin in the middle and thick at both ends, and there is an arc transition between the middle end and the two ends, the limit clamping roller 15 can clamp the wire harness in its middle position to play a limiting role, and can be suitable for clamping cables of different thicknesses. While preventing it from slipping out to the side, the wire harness is not completely fixed, so that the wire harness can be kept in a relatively loose state, so that the wire harness has a certain redundant activity space, which reduces the possibility of breakage caused by pulling during installation, maintenance, and movement and pulling due to vibration during use, thereby improving the safety of the distribution cabinet.
