[0002] An electric actuator is an actuator that uses electricity as energy in a control system. It receives electrical signals from regulating instruments, etc., changes the manipulated variable according to the size of the signal, and changes the material quantity or energy of the input or output control object to achieve the purpose of automatic regulation. It is widely used in automation equipment (such as coal mills in thermal power plants).

[0003] At present, electric actuators are generally provided with heat dissipation holes for heat dissipation. Due to the harsh working environment and high dust content of electric actuators, existing electric actuators usually do not have a structure for cleaning the dustproof mesh plate.

[0023] Example

[0024] See also Figure 1-Figure 4 The utility model provides a dustproof electric actuator, including an actuator body 100 and a dustproof component 200.

[0025] Among them, the dustproof component 200 is installed in the upper shell 110 on the surface of the actuator body 100. Through the dustproof component 200, the dust on the surface of the dustproof mesh plate 140 can be cleaned, reducing the possibility of external dust easily accumulating on the surface of the dustproof mesh plate 140, thereby causing blockage of the dustproof mesh plate 140.

[0026] See also Figure 1-Figure 3An upper shell 110 is provided on the surface of the actuator body 100, and a heat dissipation hole 120 and a dust collecting notch 130 are opened on the top of the upper shell 110. The heat dissipation hole 120 is communicated with the dust collecting notch 130, and a dustproof screen 140 is connected to the heat dissipation hole 120. In a specific implementation, the heat dissipation hole 120 is opened on the top of the upper shell 110, which is beneficial to the heat dissipation of the control elements in the actuator body 100. The rotation of the cleaning member 230 can generate centrifugal force, so that the dust moves away from the dustproof screen 140 to the dust collecting notch 130, thereby reducing the possibility of dust accumulating on the surface of the dustproof screen 140 and causing clogging of the dustproof screen 140.

[0027] In this embodiment, the upper shell 110 is installed on the upper surface of the actuator body 100 by bolts 111, and a plurality of bolts 111 are provided. In a specific implementation, the plurality of bolts 111 are used here to facilitate the stability of the upper shell 110 when connected to the actuator body 100, and to facilitate the removal of the upper shell 110 from the actuator body 100; the top of the upper shell 110 is connected to a cover plate 113 by screws 112, and a plurality of screws 112 are provided. The surface of the cover plate 113 is provided with a plurality of through holes 114, and a plurality of through holes 114 are provided.

The cover plate 113 can be removed by removing the screws 112, which is conducive to cleaning the dust in the dust collecting notch 130. Here, a plurality of through holes 114 are provided here, which is conducive to heat dissipation of the control components inside the electric actuator.

[0028] See also Figure 1-Figure 4 The dustproof assembly 200 includes a rotating member 210 and a rotating member 220. The rotating member 210 is rotatably installed in the upper shell 110. A support block 150 is installed in the upper shell 110. The rotating member 220 is rotatably installed in the support block 150. One end of the rotating member 210 is transmission-connected to the rotating member 220. One end of the rotating member 220 is connected to a cleaning member 230. The cleaning member 230 is in contact with the surface of the dustproof mesh plate 140. In a specific implementation, the rotating member 210 is rotated to drive the rotating member 220 to rotate. The rotating member 220 will drive the cleaning member 230 to rotate, so that the cleaning member 230 rotates along the surface of the dustproof mesh plate 140, which is beneficial to cleaning the dust accumulated on the surface of the dustproof mesh plate 140, reducing the possibility that external dust is easily accumulated on the surface of the dustproof mesh plate 140, thereby clogging the dustproof mesh plate 140 and affecting the possibility of heat dissipation of the control element inside the actuator body 100.

[0029] In this embodiment, the rotating member 210 includes a connecting rod 211, a first bevel gear 212 and a knob 213. The connecting rod 211 is rotatably installed in the upper shell 110, and the connecting rod 211 is respectively connected to the first bevel gear 212 and the knob 213, and the first bevel gear 212 is transmission-connected to the rotating member 220; two blocks 160 are installed on the surface of the upper shell 110, and the knob 213 is located between the two blocks 160. In a specific implementation, the knob 213 is set between the two blocks 160 here to reduce the possibility that the knob 213 will rotate automatically due to collision with external objects, and at the same time, it can provide a certain protective effect on the knob 213.

[0030] The rotating member 220 includes a rotating rod 221 and a second bevel gear 222. The rotating rod 221 is rotatably installed in the support block 150, and the rotating rod 221 is respectively connected to the second bevel gear 222 and the cleaning member 230, and the second bevel gear 222 is meshed and connected with the first bevel gear 212; a protective shell 151 is connected to the lower surface of the support block 150, and one end of the connecting rod 211, the first bevel gear 212 and the second bevel gear 222 are all located in the protective shell 151. In a specific implementation, the protective shell 151 is arranged above the control element in the electric actuator, and the connecting rod 211, the first bevel gear 212 and the second bevel gear 222 are arranged in the protective shell 151, so as to reduce the possibility of the connecting rod 211, the first bevel gear 212 and the second bevel gear 222 contacting with the control element, and at the same time, it is beneficial to protect the connecting rod 211, the first bevel gear 212 and the second bevel gear 222.

[0031] The cleaning member 230 includes a cleaning block 231 and a cleaning brush 232 . The cleaning block 231 is connected to the cleaning brush 232 and the rotating rod 221 , respectively. The cleaning brush 232 is in contact with the upper surface of the dustproof screen 140 .

[0032] Specifically, the working principle of the dustproof electric actuator is as follows: when in use, the heat dissipation holes 120 on the top of the upper shell 110 are used to dissipate heat for the control components in the actuator body 100. The dustproof mesh plate 140 can reduce the possibility that dust will enter the actuator body 100 through the heat dissipation holes 120 and damage the control components. By turning the knob 213, the connecting rod 211 and the first bevel gear 212 are driven to rotate. The first bevel gear 212 drives the second bevel gear 222 in the protective shell 151 to rotate, thereby driving the support block 150 surface The rotating rod 221 and the cleaning block 231 on the surface rotate, so that the cleaning brush 232 can rotate along the surface of the dustproof mesh plate 140, which is beneficial to cleaning the dust accumulated on the surface of the dustproof mesh plate 140. At the same time, the centrifugal force generated by the cleaning block 231 can make the dust move away from the dustproof mesh plate 140 and enter the dust collecting opening 130, thereby reducing the possibility of external dust accumulating on the surface of the dustproof mesh plate 140, thereby clogging the dustproof mesh plate 140 and affecting the heat dissipation of the control components inside the actuator body 100. The cover plate 113 is opened to clean the dust in the dust collecting opening 130.
