Description

Technical Field

[0001] The utility model relates to the technical field of switches, and in particular to a multi-core switch dedicated to electric power. Background Art

[0002] The multi-core switch for power is a network device designed specifically for the power industry. It is located in the core layer of the network and plays the role of a backbone switch. In the power system, this switch is not only responsible for high-speed forwarding of data from the aggregation layer, but also has high reliability, redundancy, throughput and low latency, thus providing a fast and reliable network architecture.

[0003] When dust accumulates on the circuit board inside the switch, it may carry conductive impurities, which may cause a short circuit on the circuit board, causing the circuit board to burn, resulting in great losses. In addition, the tiny metal particles in the dust have a certain conductivity. When these particles come into contact with the conductor on the circuit, a conductive path will be formed, resulting in a short circuit. Dust may also damage the insulation layer of the circuit, causing the insulation between circuits to fail, which is also a cause of short circuit.

[0004] Therefore, in order to avoid arc burning or short circuit caused by dust on the circuit board, it is recommended to clean the surface and inside of the equipment regularly, especially the parts such as circuit boards that are prone to dust accumulation, and keep good ventilation around the equipment to reduce dust accumulation.

[0005] However, conventional cleaning methods are nothing more than cleaning after disassembling the shell of the switch. In addition to cleaning dust, the switch may also be disassembled for upgrade maintenance or overhaul. Disassembling the shell of the switch will change the fixed airflow direction inside the switch. Disassembling the shell will cause the air outlet inside the shell to have an open disassembly port in addition to the ventilation duct, thereby reducing the airflow speed, and dust is not easy to be discharged during cleaning. In order to solve this technical problem, the utility model proposes a multi-core switch dedicated to power. Utility Model Content

[0006] The main purpose of the utility model is to provide a multi-core switch dedicated to power, which can effectively solve the problems mentioned in the background technology.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A multi-core switch dedicated to electric power comprises a switch housing, air inlets are provided on both sides of the switch housing, an air outlet is provided on the bottom surface of the switch housing, a movable door is detachably connected to the inner side of the switch housing, positioning wheels are rotatably connected to the outer surfaces of both sides of the movable door, a slide is fixedly installed on the inner side wall of the switch housing, and the bottom surface of the slide is slidably connected to the outer surface of the positioning wheel.

[0010] Preferably, a protective shell is fixedly mounted on the outer surface of the switch housing, and a grille is fixedly mounted on the inner wall of the protective shell.

[0011] Preferably, a movable groove is provided on the outer surface of the protective shell, a clamping plate is rotatably connected to the outer surface of the movable groove, and the filter material is clamped on the outer surface between the clamping plate and the grille.

[0014] Preferably, the outer surface of the protective shell is detachably connected to a drainage shell, and the inner side wall of the drainage shell is rotatably connected to a louver.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] In the utility model, through the cooperation among the switch housing, the air outlet, the air inlet, the positioning wheel, the movable door and the positioning wheel, air can enter the switch housing through the air inlet and be discharged through the air outlet at the bottom. When maintenance or cleaning is required, the screws on the movable door can be removed so that the movable door can rotate with the positioning wheel as the center of a circle. When the movable door is pushed to rotate ninety degrees, the movable door can be directly pushed to move in the direction given by the slide through the positioning wheel, so that the movable door can block the air outlet, forcing the internal air to flow out through the disassembly port where the movable door flows out, so that the air flow remains consistent and the speed of air flow slowing down is reduced, thereby solving the problem that the fixed air flow direction inside the switch will be changed after the switch housing is disassembled, making it difficult to discharge dust.

[0017] In the utility model, through the cooperation between the drainage shell, the louver and the filter material, the drainage shell can ensure that the gas entering the switch casing can pass through the louver. When the equipment needs to be transported, the louver is pushed to a closed state so that the external air no longer enters the air inlet, so that the service life of the filter material can be frozen in the storage state and the transportation state.

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1-6As shown, a multi-core switch dedicated to electric power comprises a switch housing 1, air inlets 2 are provided on both sides of the switch housing 1, an air outlet 3 is provided on the bottom surface of the switch housing 1, a movable door 4 is detachably connected to the inner side of the switch housing 1, and positioning wheels 5 are rotatably connected to the outer surfaces of both sides of the movable door 4, and a slideway 6 is fixedly installed on the inner wall of the switch housing 1, and the bottom surface of the slideway 6 is slidably connected to the outer surface of the positioning wheel 5, so that air can enter the switch housing 1 through the air inlet 2 and be discharged along the air outlet 3 at the bottom. When maintenance or cleaning is required, the screws on the movable door 4 can be removed so that the movable door 4 can rotate with the positioning wheel 5 as the center of the circle. When the movable door 4 is pushed to rotate ninety degrees, the movable door 4 can be directly pushed to move in the direction given by the slideway 6 through the positioning wheel 5, so that the movable door 4 can block the air outlet 3, forcing the internal air to flow out through the disassembly port of the movable door 4, so that the air flow remains consistent and the speed of air flow slowdown is reduced, thereby solving the problem that the fixed air flow direction inside the switch will be changed after the switch housing is disassembled, and dust is not easily discharged.

[0027] A mounting frame 7 is fixedly mounted on the outer surface of the switch housing 1 located at the air inlet 2, and a fan 8 is fixedly mounted on the outer surface of the mounting frame 7. The mounting frame 7 can provide support for the fan 8, and the fan 8 can suck in the external airflow and send it into the air inlet 2. There are two fans 8, which work alternately in the normal state. When the movable door 4 moves, the two fans 8 are started at the same time, which increases the airflow of the intake, thereby slowing down the speed of the internal airflow.

[0028] A protective shell 9 is fixedly installed on the outer surface of the switch housing 1, and a grille 10 is fixedly installed on the inner wall of the protective shell 9. The protective shell 9 can provide support for the grille 10, and the grille 10 can protect the fan 8 to prevent the fan 8 from being damaged by external objects.

[0029] An outer surface of the protective shell 9 is provided with a movable groove 11, and the outer surface of the movable groove 11 is rotatably connected with a clamping plate 12. The outer surface between the clamping plate 12 and the grille 10 clamps the filter material 18. The clamping plate 12 and the grille 10 can clamp the filter material 18. The filter material 18 can filter the incoming gas and intercept dust in the airflow to ensure that the air in the switch housing 1 is dust-free.

[0030] A reset groove 13 is provided on the inner side of the protective shell 9, and the interior of the reset groove 13 and the outer surface of the movable groove 11 are mutually connected. A reset rod 14 is fixedly installed on the outer surface of the clamping plate 12, and the outer surface of the reset rod 14 and the outer surface of the movable groove 11 are rotatably connected. The clamping plate 12 can be rotated in the movable groove 11 with the reset groove 13 as the center through the reset rod 14, so that the clamping plate 12 can be lifted, which makes it easier to replace the filter material 18.

[0031] A spiral spring 15 is sleeved on the outer surface of the reset rod 14, one end of the spiral spring 15 is fixedly mounted on the outer surface of the reset rod 14, and the other end of the spiral spring 15 is fixedly mounted on the inner surface of the reset groove 13. The spiral spring 15 can always use the reset groove 13 as a fixed point to push the reset rod 14, forcing the reset rod 14 and the clamping plate 12 to always clamp the filter material 18 without being subjected to external force.

[0032] The outer surface of the protective shell 9 is detachably connected to a drainage shell 16, and the inner wall of the drainage shell 16 is rotatably connected to a louver 17. The louvers 17 can be connected in series with each other. The drainage shell 16 can ensure that the gas entering the switch casing 1 can pass through the louver 17. When the equipment needs to be transported, the louver 17 is pushed to a closed state so that the external air no longer enters the air inlet 2, so that the service life of the filter material 18 can be frozen in the storage state and the transportation state.

[0033] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
