Description

Technical Field

[0001] This invention relates to the field of electric actuator technology, and more specifically to a miniaturized electric actuator with intelligent control. Background Technology

[0002] Electric actuators are being used more and more widely. As industries such as power plants, petrochemicals, and water conservancy facilities place increasing emphasis on automated industrial control, electric actuators are being used more and more in these industries. At the same time, the requirements for the use of electric actuators and all aspects are being further improved. Electric actuators are being used in various key positions, and their reliability and flexible application also need to meet higher requirements.

[0003] Existing intelligent control miniature electric actuators achieve precise control of fluid flow by controlling the opening and closing of valves. Although the above method can achieve the device's function of adjusting the valve position and state, when the device is in use, the rotation adjustment of the valve state is achieved through multi-gear transmission. When the valve is in a semi-open state, the impact force of the liquid can easily change the opening and closing state of the valve, resulting in poor control accuracy of the device. At the same time, in order to ensure the opening and closing of the valve in emergency situations, the device needs to be equipped with a manual lever. The separately equipped device needs to be carried by a person at all times, making the device inconvenient to use in emergency situations. Summary of the Invention

[0004] The purpose of this invention is to provide a compact electric actuator with intelligent control in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] A miniature electric actuator with intelligent control includes a housing. A motor housing is mounted on one side of the bottom of the housing. A heat-conducting plate is arranged on the outer wall of the motor housing. A motor is installed inside the motor housing. The power output end of the motor is connected to a motor rotor. A driving gear is arranged on one side of the motor rotor. A transmission shaft is fixed in the middle of the driving gear. A driven gear is connected to one side of the driving gear. A transmission gear disk one is connected to the middle of the driven gear through the transmission shaft. One side of the transmission gear disk one is connected to the transmission gear disk three through the transmission gear disk two. One end of the transmission gear disk three is connected to a connecting plate through the transmission shaft. A connecting pipe is installed on the end of the connecting plate near the transmission gear disk three. A worm gear is provided at one end away from the transmission gear disk three. A turbine is connected to one side of the worm gear. A main shaft is installed at the middle of the bottom end of the turbine. An output shaft is arranged at the middle of the top end of the turbine. A top plate is provided at the middle of the top end of the output shaft. A groove is opened at the middle of the top end of the top plate. Two slots are symmetrically opened on both sides of the bottom end of the groove. An electric turntable is arranged at the top end of the groove. Two pins are symmetrically installed on both sides of the bottom end of the electric turntable. An infrared positioning device is connected to the bottom end of the pins. A hydraulic cylinder is connected to the top end of the electric turntable. A gearbox is arranged on one side wall of the housing. An L-shaped plate is installed on one side wall of the gearbox. A magnetic suction plate is provided at the middle of the top end of the L-shaped plate. A limit insertion hole is opened on one side wall of the L-shaped plate.

[0007] Furthermore, a display screen is provided at the top center of the housing, and buttons are installed on one side of the display screen. A mounting base plate is provided on one side of the bottom of the housing. The bottom center of the mounting base plate is connected to the connector via a splicing pipe. A snap-fit ​​block is provided around the inside of the splicing pipe, and mounting holes are provided around the splicing pipe.

[0008] By adopting the above technical solution, the display screen, in conjunction with the button design, facilitates the control of the operation of the electrical components within the device.

[0009] Furthermore, the display screen and the buttons are both connected to the cabinet slot, the mounting base plate is connected to the cabinet screws, the snap-fit ​​block is connected to the splicing pipe screws, and the connector head is rotatably connected to the splicing pipe.

[0010] By adopting the above technical solution, the design of the snap-fit ​​block realizes the limiting installation of the splicing pipe to the valve connection device, and the design of the connector head facilitates the fixed connection of the valve's transmission device, so as to drive the valve to open and close.

[0011] Furthermore, the motor housing is screwed to the housing body, the motor is connected to the motor housing via a slot, and the heat-conducting plate is inserted into the motor housing.

[0012] By adopting the above technical solution, the motor housing achieves protective installation of the motor, and in conjunction with the design of the heat-conducting plate, it can dissipate heat from the motor housing to ensure the normal operation of the motor.

[0013] Furthermore, the motor is keyed to the motor rotor, the motor rotor meshes with the driving gear, and the driving gear meshes with the driven gear.

[0014] By adopting the above technical solution, the motor drives the electric rotor to rotate, providing torque to the driving gear, the driven gear, the first transmission gear disk, the second transmission gear disk, the third transmission gear disk, and the connecting disk, thereby realizing the transmission of power.

[0015] Furthermore, the drive shaft is connected to the driving gear, the driven gear, the first transmission gear disk, the second transmission gear disk, the third transmission gear disk, and the connecting disk.

[0016] By adopting the above technical solution, the design of the driving gear, the driven gear, the first transmission gear disk, the second transmission gear disk, the third transmission gear disk, and the connecting disk converts the high speed and low torque of the motor into low speed and high torque output power, so as to drive the valve mechanism to operate.

[0017] Furthermore, the first transmission gear disk meshes with the second transmission gear disk, the second transmission gear disk meshes with the third transmission gear disk, and the worm gear is inserted into the connecting disk.

[0018] By adopting the above technical solution, the design of the worm gear in conjunction with the turbine achieves a change in the direction of mechanical motion.

[0019] Furthermore, the worm gear meshes with the turbine, the main shaft and the output shaft are both plugged into the turbine, and the main shaft is screwed to the output shaft.

[0020] By adopting the above technical solution, the rotation of the turbine realizes the rotation of the main shaft and the output shaft on the turbine, thereby realizing the rotation of the valve transmission structure driven by the connector.

[0021] Furthermore, the top plate is screwed to the output shaft, the pins correspond one-to-one with the slots, and the infrared positioning device is connected to the pin slot.

[0022] By adopting the above technical solution, the design of the hydraulic cylinder in conjunction with the electric turntable facilitates the insertion pin to limit the slot, thus preventing the valve from shifting due to the impact of the liquid.

[0023] Furthermore, the hydraulic cylinder is screwed to the electric turntable, the L-shaped plate is screwed to the gearbox, and the magnetic suction plate is slotted to the L-shaped plate.

[0024] By adopting the above technical solution, the design of the L-shaped plate, the magnetic plate, and the limiting hole facilitates the magnetic installation of the lever, making it easy to access the lever at any time in an emergency. In an emergency, the lever can move the connecting pipe, realizing the manual rotation of the transmission gear disk three, thereby realizing the manual opening and closing of the valve by the device.

[0025] The specific working principle is as follows: When using the device, the base plate of the device needs to be connected to the top of the valve, realizing the connection of the snap-fit ​​block and the splicing pipe to the top of the valve. The design of the mounting hole can effectively realize its stable operation within the splicing pipe, allowing the valve's transmission device to be spliced ​​with the connector. When the device is working, the motor rotor rotates, realizing the transmission of the motor rotor to the drive gear. The drive gear can drive the transmission gear on the transmission shaft to rotate, and at the same time, the first transmission gear disk rotates synchronously, realizing the rotation of the transmission gear disk and the third transmission gear disk, so that the connecting disk can rotate at a relatively slow and uniform speed, so as to adjust the torque and realize the adjustment of the valve opening and closing speed. At the same time, the worm gear on the connecting disk rotates, realizing the rotation of the turbine, and thus realizing the rotation of the main shaft and the output shaft in the middle of the turbine. This allows the connector to adjust the valve's opening and closing state. Simultaneously, when the valve is fixed in a certain state, the electric turntable rotates, and the infrared positioning device emits infrared signals into the slot. When the infrared light encounters a target object, it is reflected back and received by the infrared receiver. By calculating the time difference between infrared emission and reception, the position of the target object can be determined, allowing the hydraulic cylinder to drive the insert on the electric turntable into the slot, achieving rapid locking of the top of the output shaft and preventing the impact force of the liquid from changing the valve's state. The display screen facilitates control of the electrical components within the device. The L-shaped plate, combined with the limiting socket and the magnetic plate, allows the device to store the equipped lever for easy access. The motor, in conjunction with the heat-conducting plate, dissipates heat generated during motor operation, preventing overheating and burnout.

[0026] The beneficial effects of this invention are as follows:

[0027] 1. Through the design of worm gear, turbine, main shaft and output shaft, when the multi-gear drives the worm gear to rotate, the main shaft and output shaft on the turbine can be rotated, thereby realizing the rotation of the valve on the connector. When the valve is in a half-open state, the electric turntable rotates, and at the same time the infrared positioning device emits infrared signals to the slot through the infrared transmitter. When the infrared light encounters the target object, it will be reflected back and received by the infrared receiver. By calculating the time difference between infrared emission and reception, the position of the target object can be determined, so that the hydraulic cylinder can drive the insert on the turntable into the slot, realizing the rapid locking of the top of the output shaft and avoiding the impact force of the liquid from changing the state of the valve.

[0028] 2. Through the design of the L-shaped plate, magnetic plate and limiting hole, when the valve of the device is opened and closed manually, the equipped lever can be directly attracted to the magnetic plate. With the limiting hole limiting one end of the lever, the L-shaped plate can effectively store the lever, avoiding the cumbersome carrying of it separately. Attached Figure Description

When the valve is in a semi-open state, the electric turntable 33 rotates. Simultaneously, the infrared positioning device 30 emits infrared signals to the slot 15 via an infrared transmitter. When the infrared light encounters a target object, it is reflected back and received by an infrared receiver. By calculating the time difference between infrared emission and reception, the position of the target object can be determined, facilitating the operation of the hydraulic cylinder 32. 2. The insert 34 on the turntable is driven into the slot 15, which realizes the quick locking of the top of the output shaft 29, and avoids the impact force of the liquid from changing the state of the valve.

A magnetic suction plate 23 is set at the middle of the top of the L-shaped plate 24. A limit insertion hole 22 is opened on one side wall of the L-shaped plate 24.

With the limit insertion hole 22 limiting one end of the lever, the L-shaped plate 24 can effectively store the lever, avoiding the cumbersome carrying of it separately.

The motor housing 5 provides protection for the motor 11.

[0042] In this embodiment, the drive shaft 19 is connected to the driving gear 14, the driven gear 13, the first transmission gear disk 18, the second transmission gear disk 17, the third transmission gear disk 12, and the connecting disk 16. The design of the driving gear 14, the driven gear 13, the first transmission gear disk 18, the second transmission gear disk 17, the third transmission gear disk 12, and the connecting disk 16 converts the high speed and low torque of the motor 11 into low speed and high torque output power, so as to drive the valve mechanism to operate.

Simultaneously, when the valve is fixed in a certain state, the electric turntable 33 rotates, and the infrared positioning device 30 emits infrared signals into the slot 15. When the infrared light encounters a target object, it is reflected back and received by the infrared receiver. By calculating the time difference between infrared emission and reception, the position of the target object can be determined, allowing the hydraulic cylinder 32 to drive the insert 34 on the electric turntable 33 into the slot 15, achieving rapid locking of the top of the output shaft 29 and preventing the impact of liquid from altering the valve's state.
