Description

Technical Field

[0001] This utility model relates to the field of electric actuator control technology, specifically to an intelligent control module for electric actuators. Background Technology

[0002] The intelligent control module of an electric actuator is the "brain" of the actuator. By integrating a microprocessor, sensors, and communication interfaces, it enables precise driving and intelligent management of valves or regulating mechanisms. It can analyze 4-20mA digital signals to control motor movement, monitor parameters such as torque and position in real time (with an accuracy of ±0.5%), and has safety functions such as stall protection and electronic limit switches. It also supports remote monitoring via the Internet of Things and is widely used in fluid control scenarios in industrial automation.

[0003] Electric actuators are mostly controlled remotely via the Internet of Things. If a leak occurs at the connection of the electric actuator, the user will not be able to detect the situation in time when operating remotely, which will lead to excessive leakage of media and waste. Moreover, the leak can easily cause other accidents. Utility Model Content

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] like Figures 1-5 As shown, this utility model provides a technical solution: an intelligent control module for an electric actuator, comprising:

[0025] The control module housing 1 has an electric actuator 11 fixedly installed at its bottom and a control module body 12 fixedly installed on its inner wall.

[0026] Leakage alarm mechanism 2 is installed on the control module housing 1 and is used to monitor the leakage of the electric actuator 11.

[0027] Backup protection mechanism 3 is located on the side of the control module housing 1 and is used to provide power supply protection in the event of a power failure.

[0028] The leakage alarm mechanism 2 includes a connecting block 21 and a storage box 25. An inner support block 251 is fixedly installed on the inner wall of the storage box 25, and a sliding rod 252 is slidably connected to the inner wall of the inner support block 251. A lifting block 253 is fixedly installed at the bottom of the sliding rod 252, and a float 254 is fixedly installed at the bottom of the lifting block 253. A trigger button 255 is fixedly installed at the bottom of the inner support block 251. The storage box 25 can receive the leaked medium from the electric actuator 11. As the liquid level in the storage box 25 rises, the buoyancy of the float 254 within the medium causes the lifting block 253 to move upward, thereby pressing the trigger button 255. The trigger button 255 then transmits a signal to the control module body 12, which in turn transmits the signal to the terminal via the Internet, facilitating timely detection of leaks during remote operation by the user. In this case, the leakage alarm function is implemented. It is worth noting that the control module body 12 and trigger button 255 in this solution are devices that can be purchased on the market by those skilled in the art. The devices have not been structurally modified in this paper. Therefore, those skilled in the art are familiar with their working principle based on their professional knowledge and can apply it proficiently. Therefore, this paper will not elaborate on it. At the same time, this solution aims to protect the physical structure, but does not protect the circuit and software control. The proposal of the processing circuit in this paper is only to supplement the explanation of the feasibility and authenticity of this utility model. This utility model does not require protection of the algorithm and circuit technology. It is worth emphasizing that although this solution does not describe the electronic control program in detail, those skilled in the art can be familiar with and apply it based on their professional knowledge.

[0029] As one implementation method in this embodiment, such as Figure 2 As shown, connecting block 1 21 is fixedly installed on the outer wall of the control module housing 1. Connecting block 22 is movably inserted into the inner cavity of connecting block 1 21. A bolt is threadedly connected to the top of connecting block 1 21, and the threaded end of the bolt movably abuts against the top of connecting block 22. Through the connection relationship design of connecting block 1 21 and connecting block 22, users can selectively install the entire storage box 25. If leakage alarm is not required, the entire storage box 25 can be removed to reduce the cost of use.

[0030] As one implementation method in this embodiment, such as Figure 2 As shown, a universal rod 23 is fixedly installed on the outer wall of the connecting block 22. A collection box 24 is fixedly installed at the end of the universal rod 23 away from the connecting block 22. A storage box 25 is fixedly connected to the bottom of the collection box 24. Through the design of the universal rod 23, the user can bend it to adjust the position of the collection box 24 so that the collection box 24 is below the electric actuator 11. The collection box 24 is used to receive the medium leaked by the electric actuator 11 and can guide it into the inner cavity of the storage box 25.

[0031] As one implementation method in this embodiment, such as Figure 5 As shown, a protrusion 13 is fixedly installed on the outer wall of the control module housing 1. A rotating component 14 is rotatably connected to the inner wall of the protrusion 13. A cover plate 15 is fixedly installed at the end of the rotating component 14. A groove 16 is opened on the top of the control module housing 1. A rubber insert 17 is fixedly connected to the outer wall of the cover plate 15. The rubber insert 17 is movably inserted into the inner cavity of the groove 16. Through the design of the protrusion 13 and the rotating component 14, the cover plate 15 is rotatably connected to the top of the control module housing 1. When the cover plate 15 is closed on the top of the control module housing 1, the rubber insert 17 will be inserted into the inside of the groove 16. This design makes it convenient for users to open and close the cover plate 15 and facilitates the maintenance of the control module body 12.

[0032] As one implementation method in this embodiment, such as Figure 4 As shown, the backup protection mechanism 3 includes a support member 31, which is fixedly installed on the outer wall of the control module housing 1. A protective housing 32 is fixedly installed on the inner wall of the support member 31. A circular cover 37 is movably inserted into the top of the protective housing 32. Through the design of the support member 31, the protective housing 32 and the circular cover 37, the backup power supply 36 can be stored. The circular cover 37 is installed on the top of the protective housing 32 by insertion, which facilitates the user to maintain the backup power supply 36.

[0033] As one implementation method in this embodiment, such as Figure 4 As shown, a through hole 33 is provided at the bottom of the protective housing 32. A limit block 34 is fixedly installed at the bottom of the inner wall of the protective housing 32. A triangular pad 35 is fixedly installed on the inner wall of the limit block 34. A backup power supply 36 is movably connected to the top of the triangular pad 35. The backup power supply 36 monitors the mains power status in real time. When a power failure or voltage abnormality is detected, the internal relay / inverter will switch to battery power supply mode in milliseconds. At the same time, the inverter circuit converts DC power to AC power to continuously power the electric actuator 11 and the control module body 12. After a power failure, the electric actuator 11 still... It can be turned on and off, making it easy for users to control and increasing the stability of use. It is worth noting that the backup power supply 36 in this solution is a device that can be purchased on the market by those skilled in the art. The device has not been structurally modified in this paper. Therefore, those skilled in the art are familiar with its working principle based on their professional knowledge and can apply it skillfully. Therefore, this paper will not elaborate on it. The limiting block 34 and the triangular pad block 35 are used to limit the insertion of the backup power supply 36. The design of the through hole 33 improves the natural heat dissipation effect of the backup power supply 36 inside the protective shell 32 when it is working.

[0034] Working principle: During use, the user can remotely control the electric actuator 11 through the terminal device using the control module body 12. If the electric actuator 11 leaks, the accumulator box 25 can receive the leaked medium. The liquid level inside the accumulator box 25 will rise accordingly. Through the buoyancy of the float 254 in the medium, the lifting block 253 can be moved upward, thereby pressing the trigger button 255. The trigger button 255 can then transmit the signal to the control module body 12, and the control module body 12 will transmit it to the terminal via the Internet. This allows the user to detect the leak in time during remote operation and realize the function of leakage alarm. The backup power supply 36 monitors the mains power status in real time. When a power failure or voltage abnormality is detected, the internal relay / inverter will switch to the battery power supply mode in milliseconds. At the same time, the inverter circuit converts DC power to AC power to continuously power the electric actuator 11 and the control module body 12.

[0035] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
