Description

Technical Field

[0001] The present invention relates to the technical field of overheat protection equipment, and specifically to a heat dissipation device for electrical equipment in a power plant. Background Art

[0002] The application of electricity marks that mankind has entered a new era. The use of electricity has brought great convenience to people's lives. Every job in life is inseparable from the application of electricity. Electricity is crucial to people. And electrical equipment is an essential part of the process of electricity application.

[0003] Electrical equipment plays a crucial role in the process of electricity application. People need to protect these devices from damage. Usually, electrical equipment is installed in a protection box. However, during use, many electrical equipment will generate heat by themselves. Since the electrical equipment is installed in the protection box, the heat dissipation of the electrical equipment is carried out through the heat dissipation holes in the protection box. The longer the electrical equipment works, the more heat is dissipated. Only dissipating heat through the heat dissipation holes will result in poor heat dissipation effect and thus low heat dissipation efficiency. Summary of the Invention

[0010] Further, one end of the motor away from the threaded rod is fixedly connected to the top of the inner wall of the protection box. A pressing groove is opened on the upper surface of the inner wall of the protection box. A limiting groove is opened at the bottom of the inner wall of the protection box.

[0012] Further, one end of the pressing plate away from the sliding plate contacts the surface of the stress plate, one end of the limiting spring away from the centralized plate is fixedly connected to the surface of the electrical equipment, one end of the stress telescopic rod away from the pressing plate is fixedly connected to the inner wall of the pressing groove, one end of the power motor away from the cooling fan is fixedly connected to the surface of the electrical equipment, the number of the centralized plates is two, the two centralized plates are symmetrically arranged with the electrical equipment as the center, and the bottom of the centralized plate is slidably connected to the inner wall of the limiting groove.

[0013] Further, the cleaning mechanism includes a cleaning plate, a cleaning brush is fixedly connected to the surface of the cleaning plate, a weighted elastic plate is fixedly connected to the end of the cleaning plate away from the cleaning brush, and a limiting spring is fixedly connected to the surface of the cleaning plate.

[0014] Further, one end of the buffer elastic rod away from the driven plate is fixedly connected to the surface of the cleaning plate, one end of the driven plate away from the buffer elastic rod is fixedly connected to the surface of the stress plate, and one end of the cleaning brush away from the cleaning plate contacts the inner wall of the protection box.

[0015] Further, the dust blocking mechanism includes a support extension rod, a dust-proof plate is fixedly connected to the end of the support extension rod, a right-angle plate is fixedly connected to the surface of the dust-proof plate, and lower pressing plates are rotatably connected to both ends of the dust-proof plate.

[0016] Further, one end of the right-angle plate away from the dust-proof plate is fixedly connected to the surface of the cleaning plate, both ends of the dust-blocking telescopic plate contact the surface of the dust-proof plate, and one end of the lower pressing plate away from the dust-proof plate is rotatably connected to the surface of the lower pressing frame.

[0017] The present invention has the following beneficial effects:

[0018] In the present invention, by providing a centralized mechanism, the motor is first started to drive the threaded rod to rotate. When the threaded rod rotates, the lower slide plate will move downward. When the lower slide plate moves, it will drive the extrusion plate to move downward. When the extrusion plate moves, it will extrude the force-bearing plate. When the force-bearing plate is extruded, it will push the centralized plate to slide on the inner wall of the limit groove in the direction of approaching each other, and extrude the limit elastic rod, so that both ends of the centralized plate contact the surface of the protective cover. When the centralized plate moves, it will extrude the limit spring. When the limit spring is extruded, it will contract in the direction of approaching each other. When the limit spring contracts to a certain position, it will limit the centralized plate, thus preventing the centralized plate from contacting the surface of the electrical equipment, and then concentrating the heat emitted by the electrical equipment. At this time, the power motor is started to drive the cooling fan to rotate. When the cooling fan rotates, it can blow the heat concentrated by the centralized plate towards the direction of the heat dissipation holes, so as to transfer the heat out, thereby achieving rapid cooling of the electrical equipment and improving the efficiency of cooling the electrical equipment.

[0019] In the present invention, by providing a cleaning mechanism, when the force-bearing plate moves, it will drive the driven plate to move in the direction of approaching each other. When the driven plate moves, it will drive the buffer elastic rod to move in the direction of approaching each other. When the buffer elastic rod moves, it will drive the cleaning plate to move in the direction of approaching each other. When the cleaning plate moves, it will drive the cleaning brush to move in the direction of approaching each other, and clean the dust on the inner wall of the heat dissipation hole to prevent the heat dissipation hole from being blocked by dust over time. When the cleaning plate moves, it will extrude the weighted elastic plate. When the weighted elastic plate is extruded, the middle part will bend. When the middle part of the weighted elastic plate bends, both ends of the weighted elastic plate will generate a thrust and push the cleaning plate towards the direction of the heat dissipation hole. When the cleaning plate moves, it will push the cleaning brush towards the direction of the heat dissipation hole, so as to clean the heat dissipation hole more deeply. When the cleaning plate moves, it will pull the buffer elastic rod to extend towards the direction of the heat dissipation hole. When the cleaning plate moves, it will extrude the limiting spring. When the limiting spring is extruded, it will contract in the direction of approaching each other. When the limiting spring contracts to a certain position, it will limit the cleaning plate to prevent the two cleaning plates from contacting each other, effectively cleaning the heat dissipation hole and preventing the heat dissipation hole from being blocked by dust.

[0020] In the present invention, by providing a dust shielding mechanism, when the cleaning plate moves, it drives the right-angled plates to move towards each other. When the right-angled plates move, they pull the dust-proof plates to move towards each other. When the dust-proof plates move, they pull the support extension rods to extend towards each other. When the dust-proof plates move, they squeeze the lower pressing plate. When the lower pressing plate is squeezed, it pushes the lower pressing frame to move downwards. When the lower pressing frame moves, it pushes the dust shielding telescopic plate to move downwards. When the dust-proof plates move, they push the dust shielding telescopic plates to contract towards each other, effectively wrapping around the periphery of the heat dissipation holes and preventing dust from flying around when cleaning the heat dissipation holes. When the dust shielding telescopic plates and the dust-proof plates limit the dust, the heat dissipation fan then blows it away.

[0021] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS
