Description

Technical Field

[0001] The present invention relates to the field of precision system cabinets, and in particular to a power distribution cabinet applied to an intelligent control system and a production process thereof. Background Art

[0002] The distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), and metering cabinet (box). It is the final equipment of the power distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in places where the load is relatively dispersed and there are fewer circuits; the motor control center is used in places where the load is concentrated and there are more circuits. They distribute the power of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load.

[0003] The difference between the distribution cabinet used in intelligent control systems and conventional meter boxes is that the heat generated inside is greater. The disadvantage of high heat generation is that if it is not relieved in time, the internal system efficiency will be reduced, which may cause the system to crash and fail to work. Therefore, the internal structure division and the heat dissipation structure on the distribution cabinet used in intelligent control systems need to ensure that they can bring better ventilation and heat dissipation performance to ensure the heat dissipation needs of the internal system.

[0004] The invention patent with Chinese patent application number 202210593475.0 discloses a heat dissipation distribution cabinet, which belongs to the technical field of power distribution equipment, including a cabinet body and a heat conducting plate installed inside the cabinet body, a partition is provided on one side of the heat conducting plate, a plurality of heat dissipation pipes are provided on the partition, and a fan is installed on the top of the cabinet body. The present invention can accelerate the speed of heat dissipation inside the cabinet, avoid heat accumulation inside the cabinet and improve the heat dissipation effect through the arrangement of heat pipes, heat conducting plates, fans, dustproof nets and first through holes. Moreover, when in use, the heat dissipated by the equipment installed on the heat conducting plates and the heat inside the cabinet are transferred to the heat pipes through the heat conducting plates, and then the fans are used to blow air to the multiple heat pipes, thereby cooling the heat pipes. The air entering and exiting the cabinet will be discharged through the first through holes, thereby completing the heat dissipation process. During the cooling process, the partition will divide the interior of the cabinet to avoid the air entering from the outside from blowing into the equipment installed on the heat conducting plates. The technical solution proposed in the above invention patent is aimed at adding external equipment such as heat pipes and fans to the distribution cabinet to improve the air flow inside the cabinet. However, the solution has the following disadvantages, namely, the additional equipment such as fans will also generate heat during their own working process, and will increase energy consumption. Furthermore, the increase of external equipment will inevitably reduce the space originally used to install the system in the cabinet, resulting in more crowded installation of intelligent control systems, which is not conducive to overall heat dissipation.

When the starting plate is forced to move downward, the V-shaped transmission rod follows the rotation and drives the push plate to be ejected outward from the inner peripheral side of the punching slot. A rotating paddle for moving the metal plate is provided in the second stamping groove.

[0022] By adopting the above technical solution, the beneficial effects of the present invention are:

[0023] 1. Compared with the existing conventional power distribution cabinet or meter box for placing electric meters, the present invention is more suitable for high-precision intelligent control systems or multi-modular systems. Specifically, the present invention separates the modules by a single accommodating cavity, and the system modules are placed in independent installation boxes. Each installation box is provided with an installation through hole, so that the modules can be connected wirelessly or electrically, wherein the first installation box and the second installation box can be flexibly moved along the length direction of the first guide rail and the second guide rail respectively. The purpose is that when the system modules need to be electrically connected, the problem of complicated wires caused by the electrical connection can be simplified by bringing the two closer together, and the problem of excessive heat caused by the complicated wires can also be avoided. The present invention provides first ventilation holes on the left and right sides of the cabinet respectively. Structure and the second ventilation structure, and ensure that the projections of the two on the vertical plane do not overlap with each other, the purpose is to achieve that when the external airflow enters the installation cavity in the cabinet through the first ventilation structure or enters the installation cavity in the cabinet through the second ventilation structure, the airflow will not flow outward at the first time, but a gas circulation flow process can be carried out in the installation cavity. The first installation box and the second installation box adopt a semi-open structure to cooperate with the first ventilation structure and the second ventilation structure. That is, the heat generated by the system module in the first installation box and the heat generated by the system module in the second installation box can be discharged outward through the opening, and then be taken away by the circulating airflow at the first time without causing mutual superposition. At the same time, the heat of the wires caused by the electrical connection between the installation boxes will also be taken away together with the circulating airflow, thereby improving the overall ventilation and heat dissipation efficiency in the cabinet.

[0024] 2. In the present invention, the first guide rail and the second guide rail are parallel to each other, which ensures the regularity of the structure in the installation cavity and avoids the technical problem of excessive heat generation due to clutter.

[0025] 3. The present invention makes structural improvements on the first ventilation hole and the second ventilation hole, so that they are completely different from the conventional ventilation holes formed by simple punching. The conventional ventilation holes only function to enable the internal and external airflows to be exchanged, that is, the airflow entering the interior from the outside will not be improved at all. The first ventilation hole and the second ventilation hole used in the present invention have a structure in which the first annular air guide plate and the second annular air guide plate are integrally formed during the punching process. The first annular air guide plate and the second annular air guide plate are formed mainly by utilizing physical principles. The first annular air guide plate and the second annular air guide plate are respectively gathered along their own axial directions, ensuring that the external airflow will have an airflow contraction process when passing through the first ventilation hole or the second ventilation hole. After the contraction process, the unit cross-sectional area of ​​the airflow is rapidly reduced, and the flow rate will increase accordingly, ensuring that the airflow will have an acceleration process when passing through the first ventilation hole or the second ventilation hole into the installation cavity, thereby improving the heat dissipation efficiency.

[0026] 4. The present invention simultaneously proposes a production process for the cabinet body, wherein the metal forming operation in step S2 can complete the integrated forming operation of punching holes and air guide plates, which simplifies the process on the one hand, and on the other hand can directly utilize the waste after stamping to form the forming material of the air guide plate, thereby achieving zero waste generation and improving the utilization rate of the metal plate.

[0027] 5. The metal stamping machine used in the present invention conveys the metal plate through the front conveyor belt and the rear conveyor belt of the metal plate. The metal plate enters the second stamping groove of the stamping lower plate through the front conveyor belt of the metal plate and is placed, and then the metal is stamped to form holes.

[0028] 6. The punching head and the punching slot in the present invention adopt an inverted truncated cone structure that cooperates with each other, the purpose is to be able to form a first annular air guide plate and a second annular air guide plate. When the punching head contacts the metal plate and moves toward the punching slot to form a ventilation hole, the residual material produced by the punching will form an annular air guide plate along the gap between the punching head and the punching slot, and the conventional punching operation is very likely to cause the punching residual material to crack, that is, the first annular air guide plate and the second annular air guide plate in this scheme, so the present invention adopts an auxiliary punching device for auxiliary punching. The principle of hole operation is that when the punching head moves downward and rests against the starting plate in the auxiliary punching device, the punching head has completely penetrated the metal plate to complete the punching operation. The starting plate moves downward under the action of external force and then drives the V-shaped transmission rod to rotate, and further drives the push plate to push toward the outer peripheral side of the punching head, which ensures that the punching residue of the metal plate is surrounded by the punching head and the push plate inside and outside, and this process is almost synchronized with the punching, that is, the auxiliary punching device starts to work at the moment the punching is completed to perform the auxiliary forming operation of the air guide plate.
