Description

Technical Field

[0001] This invention belongs to the field of electrical equipment technology, and specifically relates to an adjustable wiring harness mounting device for high-voltage switchgear. Background Technology

[0002] In the manufacturing and installation of medium- and high-voltage switchgear such as 6kV and 10kV, a large number of control, measurement, and protection wiring harnesses are typically integrated inside the cabinet. These harnesses are numerous and complex in their routing, ultimately needing to connect to the terminals of components such as circuit breakers, instrument transformers, and relay protection devices. Traditional wiring methods often use simple cable trays or cable ties for rough bundling, which has the following significant drawbacks: 1. Limited space and easy to press on terminals: Due to the limited space inside the cabinet, wire harnesses are often piled up near the terminal blocks. Some wire harnesses may directly press on the ends of other wire harnesses or terminals. Under long-term operation, this may lead to loose terminals, poor contact or even discharge, which poses a serious safety hazard.

[0003] 2. High bending stress: To avoid obstacles, the wire harness is often forcibly bent, generating large internal stress, which may damage the cable insulation layer or internal conductor under long-term action.

[0004] 3. Poor heat dissipation: Tightly bundled wires are not conducive to heat dissipation, and local overheating will accelerate insulation aging.

[0005] 4. Difficult to maintain: When it is necessary to repair or replace a cable, the cable bundles are tangled together and it is difficult to separate them individually, which brings great inconvenience to the maintenance work.

[0006] To address the aforementioned issues, it is necessary to propose a reasonably designed and effective adjustable wiring harness mounting device for high-voltage switchgear. Summary of the Invention

[0007] The present invention aims to solve at least one of the technical problems existing in the prior art, and provides an adjustable wiring harness installation device for high-voltage switchgear.

[0008] This invention provides an adjustable wire harness mounting device for high-voltage switchgear, comprising a mounting base plate, a lifting mechanism, a translation mechanism, and a wire harness mounting frame; The mounting base plate is used to fix the two opposite inner side walls of the high-voltage switchgear respectively; The lifting mechanism is disposed on the mounting base plate, the translation mechanism is fixed to the lifting mechanism, and the wire harness mounting bracket is movably connected to the end of the translation mechanism for supporting and fixing the wire harness; wherein, The lifting mechanism can drive the wire harness mounting frame to rise and fall, and the translation mechanism can drive the wire harness mounting frame to rise, fall, and translate.

[0019] Figure 1 This is a schematic diagram of an adjustable wire harness mounting device for a high-voltage switchgear according to an embodiment of the present invention. Detailed Implementation

[0020] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1 As shown, the present invention provides an adjustable wire harness mounting device 100 for high-voltage switchgear, including a mounting base plate 110, a lifting mechanism 120, a translation mechanism 130, and a wire harness mounting frame 140.

[0022] The mounting base plate 110 is used to fix two opposing inner sidewalls of the high-voltage switchgear. In this embodiment, the mounting base plate 110 is fixed to two inner sidewalls on the left and right sides of the high-voltage switchgear.

[0023] The lifting mechanism 120 is disposed on the mounting base plate 110, the translation mechanism 130 is fixed to the lifting mechanism 120, and the wire harness mounting bracket 140 is movably connected to the end of the translation mechanism 130 for supporting and fixing the wire harness.

[0024] The lifting mechanism 120 can drive the wire harness mounting frame 140 to rise and fall, and the translation mechanism 130 can drive the wire harness mounting frame 140 to rise, fall, and translate. Furthermore, the wire harness mounting frame 140 is movably connected to the end of the translation mechanism 130, which also allows for adjustment of the angle of the wire harness mounting frame 140.

[0025] Specifically, the lifting mechanism 120 raises and lowers, driving the translation mechanism 130 to raise and lower, which in turn drives the wire harness mounting frame 140 to raise and lower. The translation mechanism 130 moves horizontally, thereby driving the wire harness mounting frame 140 to move horizontally. In other words, the lifting mechanism 120 drives the wire harness mounting frame 140 to move along the Y direction, and the translation mechanism 130 drives the wire harness mounting frame 140 to move along the X direction.

[0026] This invention relates to an adjustable wire harness mounting device for high-voltage switchgear. A lifting mechanism drives the wire harness mounting frame to rise and fall, while a translation mechanism drives the frame to move horizontally and vertically. The wire harness mounting frame is movably connected to the end of the translation mechanism, allowing for angle adjustment. This device precisely moves the wire harness mounting frame to the ideal wiring position, providing the optimal path for each wire harness and fundamentally avoiding wire harness accumulation and crimped terminals. The mounting frame reduces forced bending of the wire harness, effectively lowering internal stress and extending cable life. Separating and fixing the wire harnesses separately results in clear and orderly wiring, improving aesthetics, airflow, and heat dissipation. Independently fixed wire harnesses allow for convenient operation of individual harnesses during maintenance without affecting other harnesses, significantly improving maintenance efficiency. The device can be flexibly configured and adjusted according to the internal structure and wiring requirements of different switchgear, offering strong versatility.

[0027] For example, such as Figure 1 As shown, the lifting mechanism 120 includes a guide rail 121 and a sliding base 122; the guide rail 121 is fixed to the mounting base 110 in the vertical direction; the sliding base 122 is slidably disposed on the guide rail 121.

[0028] It should be noted that the number of guide rails 121 can be one or multiple parallel ones, which can be selected according to actual needs.

[0029] For example, such as Figure 1 As shown, the lifting mechanism 120 also includes a locking member 123; the locking member 123 is disposed on the sliding base 122 and is used to lock the sliding base 122 to the guide rail 121. Specifically, in this embodiment, the locking member 123 can be a wing screw, a wrench-type locking screw, etc. For example, a wing screw with a handle is installed on the side of the sliding base 122. When the sliding base 122 slides along the guide rail 121 to a preset position, the wing screw is tightened to press against the side of the guide rail 121 to fix the sliding base 122.

[0030] In this embodiment, the lifting mechanism adopts a combination of guide rail and sliding base, which is simple in structure and easy to operate.

[0031] For example, such as Figure 1As shown, the translation mechanism 130 includes a fixed sleeve 131 and a telescopic rod 132. The fixed sleeve 131 is fixed to the sliding base 122. The first end of the telescopic rod 132 is telescopically disposed in the fixed sleeve 131, and the second end of the telescopic rod 132 is fixedly connected to the wire harness mounting frame 140. The telescopic rod 132, by extending and retracting within the fixed sleeve 131, drives the wire harness mounting frame 140 to translate.

[0032] For example, such as Figure 1 As shown, the translation mechanism 130 also includes a button 133 disposed on the outer peripheral wall of the fixed sleeve 131; when the button is in the pressed state, the telescopic rod 132 moves toward or away from the fixed sleeve 131; when the button 133 is in the reset state, the telescopic rod 132 is fixed in the fixed sleeve 131. The telescopic rod 132 is fixed at a preset position within the fixed sleeve 131 by the button 133, thereby realizing the extension and retraction of the telescopic rod 132.

[0033] In this embodiment, the translation mechanism adopts a combination of a fixed sleeve and a telescopic rod, which is simple in structure and easy to operate.

[0034] It should be noted that other structures can be used to replace the button, as long as the telescopic rod can be fixed in the preset position of the fixing sleeve. For example, a ring-shaped hand-tightening screw can be used. When the telescopic rod 132 is extended to the preset position, the hand-tightening screw is tightened to hold the telescopic rod 132, thereby fixing the telescopic rod 132. This embodiment does not specifically limit the locking structure of the telescopic rod 132, and it can be selected according to actual needs.

[0035] For example, the device further includes a plurality of fasteners, the end of the guide rail 121 is provided with a plurality of first mounting holes, and the mounting base plate 110 is provided with a plurality of second mounting holes corresponding to the first mounting holes.

[0036] The fastener passes through the first mounting hole and is inserted into the corresponding mounting hole to fix the guide rail 121 to the mounting base plate 110.

[0037] It should be noted that in this embodiment, the first mounting hole and the second mounting hole can be threaded holes, and the fastener can be a bolt, as long as the guide rail can be fixed on the mounting base plate. The choice can be made according to actual needs, and this embodiment does not make specific limitations.

[0038] For example, in this embodiment, the wire harness mounting bracket 140 is connected to the end of the translation mechanism 130 via a rotary hinge 150 to adjust the angle of the wire harness mounting bracket. Specifically, in this embodiment, the wire harness mounting bracket 140 is connected to the end of the telescopic rod 132 via a rotary hinge.

[0039] In this embodiment, the angle of the wire harness mounting bracket is adjustable, allowing it to rotate at a certain angle in the horizontal plane. This makes full use of the space in the high-voltage switchgear, enabling more rational wiring and adapting to wiring requirements in different directions.

[0040] It should be noted that the wire harness mounting bracket can also be connected to the end of the translation mechanism in other ways, as long as the angle of the wire harness mounting bracket can be adjusted. This embodiment does not impose any specific limitations.

[0041] For example, such as Figure 1 As shown, the wire harness mounting frame includes a frame 141 and a plurality of cable fasteners 142 disposed on the frame 141. The cable fasteners 142 are used to secure the wire harnesses separately. Each cable fastener 142 can secure one or a strand of cable. The number of cable fasteners 142 is not specifically limited in this embodiment and can be selected according to implementation needs. The frame 141 can be a U-shaped or rectangular frame, which can be selected according to actual needs.

[0042] The frame 141 is provided with fixing holes for the cable fixing member to pass through. The cable fixing member 142 may include Velcro straps, closable cable clips, or cable guide rings. The type of cable fixing member 142 is not specifically limited and can be selected according to implementation needs.

[0043] For example, in this embodiment, all metal parts are coated with an insulating and corrosion-resistant coating, or the entire device is made of high-strength insulating materials (such as engineering plastics, nylon, etc.) to ensure electrical safety under high-voltage conditions.

[0044] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, and the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
