Description

Technical Field

[0001] This utility model relates to the field of electric actuator technology, and in particular to a dustproof and cooling device for electric actuators. Background Technology

[0002] An electric actuator, also known as an electric actuator mechanism, is an automated device that converts electrical energy into mechanical motion. It is primarily used to control the opening, closing, regulation, or positioning of valves, mechanical devices, or other industrial equipment. It is a core actuator in industrial automation control systems, featuring high precision, rapid response, and remote control capabilities, and is widely used in petrochemical, power, water treatment, and building automation industries.

[0003] The motor is the core component of the electric actuator. During continuous operation, the motor provides stable power output. However, during continuous operation, high temperatures will accumulate inside the motor. In order to achieve dust prevention, the existing technology usually uses a sealed dustproof shell to install the motor, which affects the heat dissipation of the motor to a certain extent and has certain shortcomings. Therefore, we propose a dustproof and cooling device for electric actuators. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a dustproof and cooling device for electric actuators.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

A threaded sleeve is fixed to the bottom of the protective shell, and an air intake mechanism is threadedly connected to the bottom of the threaded sleeve. The bottom output shaft of the dual-axis motor is inserted into the air intake mechanism and connected to a fan blade.

[0007] Preferably, the number of the mesh is several groups, and the several groups of mesh are located on the side of the protective shell and are symmetrically distributed.

[0008] Preferably, the heat conduction mechanism includes an explosion-proof shell fixed to the top of the protective shell, a heat conduction plate fixed on the inner wall of the explosion-proof shell, heat dissipation fins installed on the side of the heat conduction plate, the heat dissipation fins penetrating the explosion-proof shell, and a first bearing and a second bearing respectively installed at the top and bottom of the explosion-proof shell.

[0010] Preferably, the air intake mechanism includes a dust collector housing that is threadedly installed at the bottom of a threaded sleeve.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-3 A dustproof and cooling device for an electric actuator includes a mounting plate 1, a protective shell 2 fixed on the mounting plate 1, and a mesh 3 installed on the side of the protective shell 2. The mesh 3 is arranged in several groups, symmetrically distributed on the side of the protective shell 2. A heat-conducting mechanism 4 is installed inside the protective shell 2, and a dual-axis motor 5 is installed inside the heat-conducting mechanism 4. The output shafts on both sides of the dual-axis motor 5 pass through the heat-conducting mechanism 4, and the top output shaft of the dual-axis motor 5 passes through the protective shell 2. The heat-conducting mechanism 4 includes an explosion-proof shell 41 fixed to the top of the protective shell 2, and a heat-conducting plate 42 fixed to the inner wall of the explosion-proof shell 41. Heat dissipation fins 43 are installed on the side of the protective shell 2, penetrating the explosion-proof shell 41. A first bearing 44 and a second bearing 45 are respectively installed at the top and bottom of the explosion-proof shell 41. A dual-axis motor 5 is installed inside the explosion-proof shell 41. Thermal grease is evenly applied between the dual-axis motor 5 and the heat-conducting plate 42. Several sets of heat dissipation fins 43 are present. The output shaft at the top of the dual-axis motor 5 is rotatably connected to the protective shell 2 via the first bearing 44, and the output shaft at the bottom of the dual-axis motor 5 is rotatably connected to the explosion-proof shell 41 via the second bearing 45. A threaded sleeve 6 is fixed to the bottom of the protective shell 2, and the bottom of the threaded sleeve 6 is connected by a thread. The intake mechanism 7 has an output shaft at the bottom of the dual-shaft motor 5 inserted into it and connected to a fan blade 8. The intake mechanism 7 includes a dust collector housing 71 threaded onto the bottom of a threaded sleeve 6. The conical inner wall of the dust collector housing 71 forms a 45-degree angle with the horizontal plane. An intake pipe 72 is installed on the side of the dust collector housing 71, an exhaust pipe 73 is installed on the top, and a connecting pipe 74 is installed on the bottom. A fixing seat 75 is installed at the bottom of the connecting pipe 74, and a one-way valve 76 is installed inside the fixing seat 75. The intake pipe 72 is perpendicular to the side of the dust collector housing 71. The output shaft at the bottom of the dual-shaft motor 5... The shaft is inserted into the exhaust pipe 73. When the dual-shaft motor in this utility model starts, the top and bottom output shafts rotate synchronously. The bottom output shaft drives the fan blades to generate forced airflow, which introduces external air through the intake pipe to form convection. Combined with the heat dissipation fins of the heat conduction mechanism, it accelerates heat diffusion and significantly improves heat dissipation efficiency. The conical inner wall of the dust collector is at a 45-degree angle to the horizontal plane. It is installed vertically with the intake pipe and uses centrifugal force to separate large dust particles in the air. The one-way valve prevents dust from being sucked back. The intake mechanism is detachably connected by a threaded sleeve, which is convenient for cleaning accumulated dust and can quickly dissipate heat from the motor, thus improving the service life of the motor.

[0020] When the dual-axis motor 5 starts, its top and bottom output shafts rotate synchronously. The bottom output shaft drives the fan blades 8 to rotate. The fan blades 8 introduce gas through the air intake pipe 72. External air enters the dust collector through the air intake pipe 72. Dust is deposited at the bottom due to the centrifugal force of the conical wall. The purified cold air enters the protective shell 2 through the exhaust pipe 73, forming forced convection cooling. The heat generated by the motor is transferred to the heat conduction plate 42 through thermal grease, and then diffused into the internal space of the protective shell 2 through multiple sets of heat dissipation fins 43. Finally, it is discharged from the partition 3 by the fan airflow. This can dissipate heat synchronously during the operation of the dual-axis motor 5, effectively keeping the dual-axis motor 5 at a suitable operating temperature and effectively improving the service life of the motor.

[0021] In summary, compared with the prior art, the dual-axis motor in this invention rotates synchronously at the top and bottom when it starts. The bottom output shaft drives the fan blades to generate forced airflow, which introduces external air through the air intake pipe to form convection. Combined with the heat dissipation fins of the heat conduction mechanism, it accelerates heat diffusion and significantly improves heat dissipation efficiency. The conical inner wall of the dust collector is at a 45-degree angle to the horizontal plane. Combined with the vertical installation of the air intake pipe, it uses centrifugal force to separate large dust particles in the air. The one-way valve prevents dust from being sucked back in. The air intake mechanism is detachably connected by a threaded sleeve, which facilitates cleaning of accumulated dust and can quickly dissipate heat from the motor, thus improving the motor's service life.
