Technical Field

[0001] The invention relates to the technical field of heat dissipation of control cabinets, and in particular to a control element protection structure for power plant automation. Background Art

[0002] In automatic control systems, control components play a vital role, and they are responsible for accurately regulating the working state of the controlled object. These precision components or devices are usually installed inside the control cabinet to ensure the stable operation of the system. However, when heat accumulates inside the traditional control cabinet due to operation, heat dissipation becomes a problem that needs to be solved.

[0003] In the traditional way, the operator needs to manually open the door of the control cabinet to allow air to circulate and dissipate heat from the internal control components. After the heat dissipation process is completed, the operator needs to close the door again to maintain the closedness and safety of the control cabinet. This process is not only cumbersome, but also brings many inconveniences to the effective heat dissipation of the control components, which to a certain extent limits the performance and heat dissipation efficiency of the control components and increases the limitations of heat dissipation. Summary of the invention

[0004] The purpose of the present invention is to provide a control element protection structure for power plant automation, which simplifies the heat dissipation process, solves the inconvenience of manually opening the door of a traditional control cabinet for heat dissipation, and improves the heat dissipation efficiency of the automation control element.

[0005] To achieve the above objectives, the present application proposes a control element protection structure for power plant automation, comprising:

[0006] A linkage heat dissipation mechanism is arranged on the top of the control cabinet, and comprises a heat dissipation fan and a rotating column, wherein the inner end of the heat dissipation fan is fixedly connected to the surface of the rotating column;

[0007] A power output mechanism, connected to the rotating column, is used to provide power output to the linkage heat dissipation mechanism;

[0008] The heat dissipation frame is connected to the top of the control cabinet; a plurality of heat dissipation holes are opened at the bottom of the heat dissipation frame; the heat dissipation fan extends into the heat dissipation frame from the heat dissipation slot of the control cabinet, and the rotation of the heat dissipation fan drives the heat emitted by the control element assembly to flow out from the heat dissipation holes to the outside of the control cabinet.

[0009] In one of the embodiments, the rotating column is divided into a main rotating column and a slave rotating column, and both the main rotating column and the slave rotating column are fixedly provided with a pulley, and a rotating belt is provided on the outer periphery of the pulley, wherein a worm gear is fixed on the top of the main rotating column, and the worm gear is meshed and connected with the power output mechanism.

[0010] In one of the embodiments, a first support frame is movably connected to the top of the slave rotating column, and the first support frame is fixedly connected to the top outer wall of the control cabinet; the main rotating column passes through a second support frame and is connected to the worm gear, and the second support frame is fixedly connected to the top outer wall of the control cabinet.

[0011] In one of the embodiments, the main rotating column and the bottom of the slave rotating column are movably connected to a base, and the base is fixedly connected to the bottom wall of the heat dissipation frame.

[0012] In one embodiment, the power output mechanism includes a power motor fixed on a motor frame, the motor frame is fixedly connected to the top of the control cabinet, the output end of the power motor is fixedly connected to a worm, and the worm is meshingly connected to a worm wheel.

[0013] In one embodiment, the end of the worm extends into a support plate, and the support plate is fixedly connected to the second support frame.

[0014] In one of the embodiments, a wear-resistant pad is provided between the support plate and the worm.

[0015] In one embodiment, a wear-resistant sleeve is provided between the second support frame and the main rotating column.

[0016] In one of the embodiments, reinforcement blocks are connected to both sides of the heat dissipation frame, and the reinforcement blocks are fixedly connected to the top inner wall of the control cabinet.

[0017] In one of the embodiments, a plurality of rows of control element assemblies are arranged in the control cabinet, a partition is arranged between two adjacent rows of control element assemblies, and a plurality of heat dissipation holes which are equally spaced are opened on the partition.

[0018] Compared with the prior art, the above technical scheme adopted by the present invention has the following advantages: 1. When heat dissipation is needed inside the control cabinet, the power motor is started, the power motor drives the worm to rotate, the rotation of the worm drives the worm wheel to rotate, the rotation of the worm wheel drives the main rotating column to rotate, the rotation of the main rotating column drives the pulley on the main rotating column to rotate, and then the pulley on the slave rotating column is driven by the rotating belt to rotate the slave rotating column, the main rotating column and the slave rotating column both drive the cooling fan to rotate, the rotation of the cooling fan drives the heat emitted by the control element assembly inside the control cabinet to flow out to the outside of the control cabinet, thereby having the advantage of easy heat dissipation, and the control element assembly inside the control cabinet can be cooled by the coordinated use of the power output mechanism and the linkage heat dissipation mechanism, so that the heat dissipation of the control element is not limited.
