Therefore, we should increase investment in electrical automation, expand research and development projects in electrical automation, develop the talent market for electrical automation, and promote my country's economy.
[0003] During operation, PLCs can generate heat inside the controller due to factors such as component operation and unstable voltage and current. Excessive heat can not only damage electrical components and affect the normal operation of related equipment, but also pose significant safety hazards.
[0004] However, the heat dissipation structure of existing control devices is not easy to disassemble. This inconvenience may lead users to neglect cleaning and maintenance, resulting in the accumulation of dust or debris, reduced heat dissipation efficiency, increased internal temperature of the equipment, and impact on PLC performance and lifespan. It may also trigger overheat protection or unexpected shutdown, affecting production continuity. To address these issues, we propose a PLC electrical automation control device. Utility Model Content
[0005] The purpose of this invention is to provide a PLC electrical automation control device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: A PLC electrical automation control device includes a device body. A base is fixedly connected to each of the four lower corners of the device body, and a mounting plate is fixedly connected to the outer side of each base. A main controller is fixedly installed on the upper left side of the device body, and a first connecting plate is fixedly connected to both the front and rear ends of the main controller.

[0009] Preferably, the fixing frame is arranged in an L-shape, and the fixing frame is distributed at the upper and lower ends of the fixing plate, with the two sets of fixing frames facing each other.
[0010] Preferably, the second connecting plate is fixedly mounted on the fixed frame by a locking bolt. Both the second connecting plate and the fixed frame are provided with locking grooves that cooperate with the locking bolt, so that the second connecting plate can be mounted on the fixed frame by the locking bolt.
[0011] Preferably, there are two third connecting plates, and an electric push rod is engaged at the middle position of the two third connecting plates.

[0015] The main controller integrates a temperature sensor and a PLC controller to monitor the equipment status in real time. The electric actuator is controlled by the PLC to achieve automated operation. The temperature sensor monitors the equipment temperature in real time. When the internal temperature of the device reaches a certain value, the sensor transmits the signal to the PLC controller. The PLC controller controls the electric actuator, which pushes the fixed plate outward, creating a gap between the device and the fixed plate. This gap allows heat to dissipate, preventing overheating and damage to the internal components. The PLC controller can automatically adjust the heat dissipation strategy based on the data. The electric actuator can be remotely controlled, reducing manual intervention and improving efficiency and safety. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4This utility model provides a technical solution: a PLC electrical automation control device, including a device body 1. Bases 2 are fixedly connected to the four corners of the lower end of the device body 1, and mounting plates 3 are fixedly connected to the outer sides of the bases 2. A main controller 4 is fixedly installed on the upper left side of the device body 1, and first connecting plates 5 are fixedly connected to both the front and rear ends of the main controller 4. Fixing frames 6 are fixedly connected to both the left and right sides of the device body 1, and electric push rods 7 are fixedly installed on the fixing frames 6. Second connecting plates 8 are fixedly connected to both the front and rear ends of the electric push rods 7. Fixing plates 9 are engaged at the middle positions of both the left and right sides of the device body 1, and a third connecting plate 10 is fixedly connected to one side of the fixing plate 9. A fixing bolt 11 is inserted into the third connecting plate 10, and a nut 12 is sleeved on the other end of the fixing bolt 11. Protective covers 13 are fixedly connected to the middle positions of both the left and right sides of the device body 1. For the application scenarios of the electric push rods 7 in this device, a suitable model with a thrust of 500N to 1000N (such as RODUCTS) can be selected. RLA series), RODUCTS RLA series and other small and medium-sized electric linear actuators are usually small in size and light in weight, making them suitable for integration into PLC devices with limited space. Electric linear actuators of 500N to 1000N usually have lower power (such as 24V DC power supply), which is suitable for the power output capability of PLC controllers and reduces energy consumption.
[0024] Mounting plate 3 and base 2 form an L-shaped structure. Mounting plate 3 has mounting grooves. The main controller 4 consists of a temperature sensor and a PLC controller. The front and rear ends of the main controller 4 are fixedly connected to the first connecting plate 5. The first connecting plate 5 is fixedly installed on the inner wall of the device body 1 by locking bolts. Both the first connecting plate 5 and the device body 1 have locking grooves that cooperate with the locking bolts. The L-shaped structure forms a stable support frame through the vertical connection of base 2 and mounting plate 3, effectively distributing the weight of the device body 1 and preventing the equipment from shaking or tilting. It is suitable for complex working conditions (such as factory environments with high vibration or outdoor installation), enhancing the overall impact resistance. The main controller 4, consisting of a temperature sensor and a PLC controller, integrates environmental monitoring and automatic control functions, reducing the complexity of external wiring. The temperature sensor detects the equipment temperature in real time, and the PLC controller adjusts the heat dissipation or alarm based on the data, improving efficiency. To enhance the level of intelligence, the main controller 4 is fixed to the inner wall of the device body 1 via the first connecting plate 5, with connections at both the front and rear ends, ensuring the stability of the main controller 4 and preventing loosening or damage due to vibration. The first connecting plate 5 and the device body 1 are fixed together by locking bolts and locking slots, eliminating the need for welding or glue, facilitating disassembly and maintenance. The modular design allows the main controller 4 to be disassembled independently, eliminating the need to disassemble the entire device for replacement or upgrades, reducing maintenance costs and downtime. The locking bolts are inserted into the locking slots of the first connecting plate 5 and the device body 1, forming a mechanical interlock structure to ensure that the main controller 4 will not shift or fall off during equipment operation. Compared to screw fixing, the locking bolts have stronger vibration resistance and are suitable for high-vibration environments. The plug-in design of the locking bolts simplifies the installation process, eliminating the need to tighten screws and improving assembly efficiency. During maintenance, the main controller 4 or the first connecting plate 5 can be removed simply by pulling out the locking bolts, making operation convenient.
[0025] The fixed frame 6 is L-shaped and distributed at the upper and lower ends of the fixed plate 9, with the two sets of fixed frames 6 facing each other. The second connecting plate 8 is fixedly installed on the fixed frame 6 by locking bolts. Both the second connecting plate 8 and the fixed frame 6 have locking grooves that cooperate with the locking bolts. There are two third connecting plates 10, and an electric push rod 7 is engaged in the middle of the two third connecting plates 10. The fixing bolt 11 is inserted into the third connecting plate 10 and the electric push rod 7, and a gasket is fitted on the fixing bolt 11. The third connecting plate 10 and the electric push rod 7 are connected by the fixing bolt 11. The upper end of the protective cover 13 is sloping, and the lower end of the protective cover 13 is open. A dustproof net is fixedly connected to the lower end of the protective cover 13. The L-shaped fixed frame 6 forms a stable support frame by combining the vertical and horizontal sides, effectively dispersing the pushing or pulling force of the electric push rod 7 and preventing deformation or displacement. The second connecting plate 8 cooperates with the locking groove of the fixed frame 6 by locking bolts. The mechanical interlock structure ensures the stability of the electric push rod 7, preventing displacement due to excessive thrust. During maintenance, the second connecting plate 8 can be removed or the electric push rod 7 can be replaced simply by pulling out the locking bolt, making operation convenient. The two third connecting plates 10 are firmly fixed to the electric push rod 7 by fixing bolts 11 and washers, ensuring that the electric push rod 7 will not shake or tilt during operation. The washers can evenly distribute the tightening force, preventing stress concentration that could damage the third connecting plate 10 or the electric push rod 7. The detachable design of the third connecting plate 10 and the electric push rod 7 supports quick replacement or position adjustment of the electric push rod 7 to adapt to different working conditions. The threaded connection of the fixing bolts 11 facilitates precise adjustment of the initial position of the electric push rod 7, ensuring operational accuracy. The upper end of the protective cover 13 has a sloping structure, which can effectively guide condensate or dust to slide off. The opening structure at the lower end of the protective cover 13, combined with a dustproof net, ensures ventilation and heat dissipation while preventing dust and debris from entering the equipment, reducing the risk of failure.
[0026] Working principle: The device body 1 can be installed through the mounting holes on the mounting plate 3. When the device body 1 is working, a certain temperature is generated inside. The temperature sensor collects the temperature data inside the device body 1 in real time and transmits it to the PLC controller. The PLC controller determines whether heat dissipation or protection is needed based on the temperature data. When the temperature is too high, the PLC controller issues a command to drive the electric push rod 7 to move. The electric push rod 7 extends or retracts, pushing the fixing plate 9 to open or close.
[0027] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
