Description

Technical Field

[0001] The invention relates to the technical field of line splitting, in particular to a line splitting mechanism for a high and low voltage power distribution cabinet. Background Art

[0002] The branching mechanism for high and low voltage distribution cabinets is a device used to reasonably distribute and manage the wires and cables entering and leaving the distribution cabinet. It mainly plays the role of sorting out the lines, ensuring the safe and orderly connection of the lines, and facilitating maintenance and inspection. In the complex electrical system of the distribution cabinet, the branching mechanism can effectively avoid line confusion and reduce electromagnetic interference between lines. In the prior art, there are multiple lines connected in the high and low voltage distribution cabinet, and the lines need to be organized and divided by the branching mechanism to make the lines neat and orderly, saving space inside the cabinet. At the same time, when maintenance personnel perform maintenance, it is convenient for them to quickly find the corresponding lines.

[0003] However, when the existing branching mechanism is branching, the lines are fixed uniformly. When maintenance is carried out, other lines have limit failure. After the maintenance is completed, the lines need to be re-arranged and branched, which is inconvenient to use and has inconvenience in heat dissipation. Therefore, a new design is made to address this situation. Summary of the invention

The composite shell is used to store electronic circuits. The receiving blocks are connected to the straight-through tube to support the composite shell. The straight-through tube is fixedly connected between the opposite surfaces of the receiving blocks. At the same time, the circuit enters from one side of the bottom of the composite shell, passes through the straight-through tube, and passes out from the top of the composite shell to protect the circuit. Secondly, the line branching effect of the circuit is achieved to avoid the entanglement of the circuit, keep the circuit smooth and connected, thereby extending the service life of the circuit, reducing electromagnetic interference between the circuits, and keeping the internal circuits of the equipment in order, which is convenient for subsequent maintenance and replacement. A clamping mechanism is fixedly connected to the side of the outside of the receiving block away from the inner wall of the composite shell.

[0014] The present invention provides a branching mechanism for a high and low voltage power distribution cabinet. It has the following beneficial effects:

[0015] 1. The branching mechanism for the high and low voltage distribution cabinet is designed with a composite mechanism. The composite shell is used to store electronic circuits. The receiving block is connected to the straight-through pipe to support the composite shell. At the same time, the line enters from one side of the bottom of the composite shell, passes through the straight-through pipe, and passes out from the top of the composite shell to protect the line. Secondly, the line branching effect is achieved to avoid the line from being entangled, and the line is kept smooth and connected, thereby extending the service life of the line, reducing electromagnetic interference between lines, and keeping the internal lines of the equipment in order, which is convenient for subsequent maintenance and replacement. The clamping mechanism clamps the U-shaped tube to support the components. After a long period of operation, the line temperature rises. The U-shaped tube adopts a U-shaped structure in the middle of the pipeline, which plays a certain buffering and compensating role in thermal expansion and contraction, prevents the pipeline from being damaged due to excessive thermal stress, and maintains the stability of the components. A processing mechanism is set on one side of the composite shell close to the circular incision, and the inside of the composite shell is ventilated through the processing mechanism to achieve the effect of ventilation and heat dissipation, thereby reducing the probability of overheating and failure of the line.

[0016] 2. The line distribution mechanism for the high and low voltage distribution cabinet is designed through a processing mechanism, and a bearing plate is arranged on the top of the composite shell. By placing the flow pipe inside the composite shell, it is convenient to disassemble and install. A cleaning mechanism is arranged inside the flow pipe. When the flow pipe is operated for a long time, the flow pipe is taken out, and the cleaning mechanism components are swung up and down to make the cleaning mechanism components slide inside the flow pipe, so as to achieve the cleaning effect of the flow pipe, avoid excessive dust affecting the ventilation effect, prevent the groove from being blocked, and facilitate wiping the surface of the cleaning component, so as to facilitate repeated operation inside the equipment. During the sliding process of the cleaning mechanism, the buffer mechanism plays a role of shock absorption and buffering, reduces the collision between the cleaning mechanism and the components during the sliding process, reduces the wear between the two, thereby extending the service life of the components and avoiding affecting the operation of the components. The second mesh plate and the first mesh plate are connected on one side of the flow pipe. The effect of air convection on both sides is achieved, the amount of air entering is increased, and the internal temperature of the equipment is adjusted faster. The second mesh plate adopts a plug-in connection method. It can be disassembled when the circulation tube is taken out, which is convenient for the discharge of internal dust and impurities. The external ring is squeezed by the fixing mechanism to achieve the effect of fixing the components, which is convenient for the components to maintain stable ventilation. The external ring is made of plastic material. When the components are clamped, it plays a protective role on the circulation tube and reduces the wear caused by clamping. At the same time, when the components are placed inside the composite shell, it plays the role of supporting the components. Tube surface slots are opened on the surface of the circulation tube to achieve the effect of ventilation and heat dissipation, thereby reducing the internal temperature of the equipment through ventilation and avoiding line failure caused by the increase of internal temperature of the equipment. The tube surface slot adopts a structure with one end wide and the other end narrow. According to Bernoulli's principle, the gas flow rate is increased by compressing the pipe diameter, thereby improving the heat dissipation efficiency.

[0017] 3. The branching mechanism of the high and low voltage distribution cabinet is designed with a cleaning mechanism. The bracket is rotated to slide on the outside of the fixed frame, so that the friction plate rubs on the inner wall of the circulation pipe, so as to achieve the effect of cleaning dust and impurities, avoid dust precipitation on the inner wall of the component after long-term operation, thereby affecting the ventilation effect and preventing dust from clogging the inner wall of the component. By opening a square groove, the contact area is increased by opening the groove, and the cleaning effect is improved. Secondly, the chip removal effect is enhanced by opening the groove, and the dust adsorption on the surface of the component is reduced to avoid affecting the subsequent friction effect.

[0018] Fourth, the line distribution mechanism for the high and low voltage distribution cabinet is designed with a buffer mechanism. As the rotating bracket slides on the surface of the fixed frame, the rotating bracket collides with the connecting bracket, causing the connecting bracket to squeeze and contract the spring coil, thereby achieving the effect of shock absorption and buffering, reducing the amplitude generated by the impact of components, avoiding collision of components during sliding and causing serious wear of components, thereby extending the service life of the components, and at the same time, through the reaction of the spring coil, the sliding speed of the components on the fixed frame is increased, thereby further improving the cleaning efficiency.

[0019] 5. The line distribution mechanism of the high and low voltage distribution cabinet is designed with a limiting mechanism. The line passes through the inner side of the limiting shell, and the line surface squeezes the connecting plate to shrink the spring frame, so as to facilitate the adjustment of the squeezing effect on the line diameter. At the same time, the line is clamped and fixed by the support of the spring frame to prevent external force from pulling the line, so as to avoid damage to the line, thereby maintaining the integrity of the line operation. At the same time, the connecting plate is swung laterally to increase the contact area with the line, further improve the friction effect, and increase the pulling and fixing effect. A silicone ring is set on the surface of the connecting plate to protect the components, reduce external friction on the components, thereby reducing component wear and extending the service life of the components. The wear resistance is increased by the silicone material, and the friction is increased by opening a rubber ring groove, thereby improving the fixing effect of the components and further improving the braking effect of the line pulling.

Secondly, it achieves the effect of dividing the circuit, avoiding the entanglement of the circuit, keeping the circuit smooth and connected, thereby extending the service life of the circuit, reducing electromagnetic interference between the circuits, and keeping the internal circuits of the equipment in order, which is convenient for subsequent maintenance and replacement. The clamping mechanism 13 clamps the U-shaped tube 14 to support the components. After a long period of operation, the temperature of the line rises. The middle part of the U-shaped tube 14 adopts a U-shaped structure to It plays a certain buffering and compensating role in thermal expansion and contraction, preventing the pipeline from being damaged due to excessive thermal stress, thereby maintaining the stability of the components.

The line passes through the inner side of the limiting shell 31, and the line surface squeezes the connecting plate 35 to shrink the spring frame 34, so as to facilitate the adjustment of the squeezing effect on the line diameter. At the same time, the line is clamped and fixed by the support of the spring frame 34 to prevent external force from pulling the line, so as to avoid damage to the line, thereby maintaining the integrity of the line operation. At the same time, the connecting plate 35 is swung horizontally to increase the contact area with the line, further improve the friction effect, and increase the pulling and fixing effect.

[0041] The outer side of the connecting plate 35 is fixedly connected with a silicone ring 36, and a rubber ring groove 37 is provided on the outer side of the silicone ring 36 away from the connecting plate 35. The silicone ring 36 is provided on the surface of the connecting plate 35 to protect the components, reduce the friction of the components from the outside, thereby reducing the wear of the components and extending the service life of the components. The wear resistance is increased by the silicone material, and the friction is increased by providing the rubber ring groove 37, thereby improving the fixing effect of the components and further improving the braking effect of the line traction.

[0042] When in use, the limiting mechanism 3 is arranged on the outside of the composite shell 11, and the staff passes the line from one side of the limiting mechanism 3 into the inside of the composite shell 11, and wraps the line through the straight tube 15 to keep the line straight, prevent the line from being entangled, and keep the line smooth and connected, thereby extending the service life of the line, reducing electromagnetic interference between lines, and keeping the internal lines of the equipment in order, which is convenient for subsequent maintenance and replacement. At the same time, the line is clamped by the limiting mechanism 3 to maintain the stability of the line and prevent the line from being dragged by external forces, thereby reducing the failure rate of the line and avoiding damage to the line due to dragging, thereby extending the service life of the line. A processing mechanism 2 is set on the side of the outside of the composite shell 11 near the circular cutout 16, and the flow tube 23 is placed into the composite shell 11 from the top of the carrier plate 21, and a tube surface slot 29 is opened on the outside of the flow tube 23 to achieve the effect of ventilation and heat dissipation, thereby reducing the composite shell. 11 internal temperature, avoid long-term operation of the line, when the composite shell 11 is closed, the surface temperature of the line rises, and the line is prevented from being partially overheated and causing line failure. The flow pipe 23 is clamped by the fixing mechanism 22 to maintain the stability of the flow pipe 23, and avoid sliding of the components during daily use, thereby affecting the daily use efficiency of the components. After the processing mechanism 2 has been ventilated for a long time, dust is easily accumulated inside the flow pipe 23, thereby affecting the ventilation effect. Therefore, it is convenient to clean by disassembling the flow pipe 23, and the surface of the flow pipe 23 is wiped to reduce external dust. At the same time, a cleaning mechanism 27 is arranged inside the flow pipe 23, and the flow pipe 23 is shaken up and down to promote the operation of the cleaning mechanism 27. The friction plate 273 is rubbed against the inner wall of the flow pipe 23 by sliding, so as to facilitate the cleaning of impurities on the inner wall, prevent impurities from accumulating and causing blockage, maintain the ventilation effect of the equipment, reduce the difficulty of cleaning, and facilitate repeated use.
