Description

Technical Field

[0001] This utility model relates to the field of electric actuator technology, and in particular to an electric actuator that is easy to dissipate heat. Background Technology

[0002] Electric actuators are widely used as components for transporting workpieces, such as sliders. In these actuators, the lead screw is rotatably driven by the rotational torque of a rotary drive source, such as a motor. Currently, electric actuators are also widely used in the switchgear of power distribution cabinets. The power trolley is mounted on a track on the base plate of the high-voltage power distribution cabinet, and the electric actuator is installed on the base plate. Operators can push and pull the power trolley by driving the electric actuator, facilitating the installation, maintenance, and operation of the electrical equipment on the power trolley.

[0003] A search revealed in Publication No. CN221806658U disclosed an electric actuator with convenient heat dissipation, comprising a device housing with a transmission cavity inside. A servo motor is arranged in the transmission cavity, and a threaded rod is connected to the output end of the servo motor. A transmission slider is slidably arranged in the transmission cavity. Through the provided plug-in block, cooling fan, and filter, outside air is delivered to the transmission cavity by the cooling fan, thereby achieving the purpose of cooling the servo motor. At the same time, the filter can filter dust and impurities in the air, preventing a large amount of dust from adhering to the surface of the servo motor and affecting the cooling effect. When there is a lot of dust on the filter and it needs to be cleaned, the plug-in block can be removed from the plug-in slot, so that the filter can be cleaned or replaced. This also facilitates the maintenance of the cooling fan, thereby improving the service life of the heat dissipation device and ensuring its heat dissipation and cooling effect.

[0004] While the above solutions allow for cleaning or replacing the filter and facilitate maintenance of the cooling fan, thereby extending the lifespan of the cooling device and ensuring its cooling effect, they do not enable timely cleaning of the filter. Therefore, we propose an electric actuator that facilitates heat dissipation. Utility Model Content

[0005] The main purpose of this utility model is to provide an electric actuator that facilitates heat dissipation. By setting up a heat dissipation unit and a cleaning unit, it solves the problem of not being able to clean the filter screen in a timely manner.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An electric actuator that facilitates heat dissipation includes a housing unit, a moving unit and a heat dissipation unit disposed inside the housing unit, and a cleaning unit disposed on the side of the housing unit, wherein the heat dissipation unit is located above the moving unit.

[0008] The heat dissipation unit includes a fixed box installed on the top wall of the outer casing unit, a fan installed inside the fixed box, and a water-cooling component disposed inside the outer casing unit;

[0009] The cleaning unit includes a rotating shaft movably mounted on the surface of the housing unit, a second drive motor mounted on the input end of the rotating shaft, a connecting plate mounted on the side wall of the rotating shaft, and a cleaning brush mounted on the inner side wall of the connecting plate.

[0010] Preferably, the housing unit includes a device housing, a mounting groove formed in the side wall of the device housing, a filter plate disposed inside the mounting groove, and a locking member disposed between the device housing and the filter plate.

[0011] Preferably, the engaging component includes a movable through hole formed in the side wall of the mounting groove, a movable rod that is movably observed and disposed in the movable through hole, an engaging seat installed at one end of the movable rod located inside the mounting groove, an engaging groove formed in the side wall of the filter plate, a tension seat installed at the other end of the movable rod, and a return spring sleeved on the circumferential side of the movable rod, with one end fixedly connected to the engaging seat and the other end fixedly connected to the side wall of the mounting groove.

[0012] Preferably, the moving unit includes a fixed groove formed in the bottom wall of the device housing, a threaded shaft movably disposed in the fixed groove, a first drive motor mounted on the input end of the threaded shaft, and a moving part disposed on the threaded shaft.

[0013] Preferably, the movable component includes a movable seat mounted on the circumferential side of the threaded shaft, and a movable frame mounted on top of the movable seat.

[0014] Preferably, the moving unit further includes a limiting washer installed on the inner side wall of the fixed groove, and the limiting washer is sleeved on the circumferential side of the threaded shaft.

[0015] Preferably, the water-cooled component includes a liquid cooling tank installed on the inner wall of the device housing, a suction pump installed on the surface of the liquid cooling tank, a water suction pipe installed at the input end of the suction pump and communicating with the liquid cooling tank, and a loop-shaped water delivery pipe installed at the output end of the suction pump and communicating with the liquid cooling tank.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In this invention, through the heat dissipation unit and the cleaning unit, when heat dissipation of the electric actuator is required, the suction pump draws out the coolant from the liquid cooling tank through the water pipe and inputs it into the liquid cooling tank through the loop-shaped water supply pipe. At the same time, the fan works, thereby generating a cool airflow that blows towards the first drive motor, thus achieving rapid heat dissipation of the electric actuator. When heat dissipation is in progress, when the drive shaft of the second drive motor rotates, the connecting plate can drive the cleaning brush to rotate synchronously with the rotating shaft, thereby achieving timely cleaning of the filter plate surface.
