Description

Technical Field

[0001] This utility model relates to the field of pneumatic actuator technology, specifically a pneumatic actuator with an explosion-proof protection mechanism. Background Technology

[0002] As an automated device powered by compressed air, pneumatic actuators play a key role in industrial automation due to their significant advantages of being clean and environmentally friendly, responding quickly, being safe and reliable, and cost-effective. They are widely used in various scenarios that require rapid and precise motion control, and have become an indispensable component for promoting the efficient operation of modern industry.

[0003] A search revealed a pneumatic actuator with a protective structure disclosed in Chinese utility model patent publication number CN221278622U. This utility model patent describes a pneumatic actuator with a protective structure that incorporates a cooling device. A fan draws external air into the cooling device through an air inlet on its side. After being cooled by a cooling fin, the air is blown into the housing by the fan. The heat generated by the cooling fin is transferred to the heat sink through a heat conduction fin, then discharged through a heat dissipation hole, and finally cooled by a cooling fan. The cool air descends from the top of the housing to the bottom, cooling the pneumatic actuator body during this process, thus extending its lifespan and saving operating costs. However, this pneumatic actuator with a protective structure relies on a fan and heat sink to generate cool air. While this method can produce cool air, its cooling efficiency is extremely low, and the high airflow from the fan makes it difficult to effectively dissipate air, resulting in limited internal heat dissipation. Therefore, a pneumatic actuator with an explosion-proof protection mechanism is proposed. Utility Model Content

[0020] 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.

[0021] Please see Figure 1-4 A pneumatic actuator with an explosion-proof protection mechanism includes a housing 1, an installation component 2 is provided inside the housing 1, a pneumatic actuator body 3 is provided on the top of the installation component 2, an explosion-proof protection structure 4 is provided inside the housing 1, and a heat dissipation structure 5 is provided inside the housing 1.

[0022] The heat dissipation structure 5 includes a ventilation pipe 501. The ventilation pipe 501 is fixedly installed on the outer surface of the housing 1. A two-way threaded rod 502 is rotatably connected inside the ventilation pipe 501. A baffle 503 is threadedly connected to the outer surface of the two-way threaded rod 502. A filter plate 504 is inserted into the ventilation pipe 501. A first fan 505 is fixedly installed inside the housing 1. A second fan 506 is fixedly installed on the back of the housing 1. A refrigeration box 507 is fixedly installed on the back of the housing 1. A compressor 508 is fixedly installed on the inner bottom wall of the refrigeration box 507. An air exchanger 509 is fixedly installed on the inner bottom wall of the refrigeration box 507. An oil-free converter 510 is fixedly installed on the inner bottom wall of the refrigeration box 507. A dryer 511 is fixedly installed inside the refrigeration box 507.

[0023] Specifically, such as Figure 2 As shown, the working principle of the mounting component 2, the pneumatic actuator body 3, and the explosion-proof protection structure 4 is the same as that of the prior art in the comparative example. The housing 1 can enclose the pneumatic actuator body 3 inside, which can play the role of explosion protection. At the same time, if an explosion occurs, the explosion-proof plate 404 drives the I-shaped extension rod 402 to move into the extension sleeve 401 and squeezes the spring body 403, thereby absorbing and weakening the impact of the explosion and playing a protective role.

[0024] Specifically, such as Figure 2As shown, the device has two heat dissipation methods. Two filter plates 504 are inserted into the two ventilation pipes 501 respectively to prevent external dust or impurities from entering the interior of the housing 1. Then, rotating the corresponding bidirectional threaded rod 502 can drive the corresponding two baffles 503 to move relative to each other, thereby restoring the ventilation function of the two ventilation pipes 501. Then, the two first fans 505 are turned on. One first fan 505 is responsible for sending outside air into the interior of the housing 1, and the other first fan 505 assists in exhausting the existing heat inside the housing 1. This setting can increase the air circulation inside the housing 1, thereby dissipating heat and cooling the internal temperature of the housing 1.

[0025] Specifically, such as Figure 4 As shown, if the first method of air cooling cannot meet the current heat dissipation and cooling effect, the compressor 508 is turned on to draw air into the compressor 508 for compression. The compressed air is sent to the air exchanger 509 for preheating. After preheating, the air is sent to the oil-free converter 510 for further filtration and purification, making it drier and cleaner. Finally, this air is sent back to the air exchanger 509 for cooling. The cooled compressed air then enters the dryer 511 to remove moisture, and is then sent into the interior of the cold air chamber. It is then sent into the interior of the housing 1 by the second fan 506. The cold air rapidly dissipates and cools the interior temperature of the housing 1. Then, by rotating the bidirectional threaded rod 502 in the opposite direction, the baffles 503 are moved closer together, thereby closing the two ventilation pipes 501 and restoring the interior of the housing 1 to a closed state, thus improving the cooling and heat preservation effect inside the housing 1.

[0026] Specifically, such as Figure 1 As shown, the control panel is electrically connected to the internal electrical equipment. The control panel, along with control buttons, sends control commands to each component via control signal lines. These signal lines can be analog signal lines such as 4-20mA current signals, digital signal lines such as RS485 communication interfaces, or simple switch signal lines. The control signals from the control panel are transmitted to the control units of each component via these signal lines. By operating the control system, the control panel controls the components inside the device, enabling the start and stop of each component. Upon receiving a start command, the controller sends corresponding control signals to each component to start it. Upon receiving a stop command, it sends a stop signal to stop each component from working. The operating parameters of each component can be set on the control panel interface. These parameter settings are converted into corresponding control signals and sent to the control units of each component, thereby achieving precise adjustment of the component's operating status. The control panel has a monitoring function for the operating status of each component, capable of displaying the operating parameters and status information of each component in real time.

[0027] In summary, this pneumatic actuator with an explosion-proof protection mechanism is installed on the pneumatic actuator body 3 through the mounting component 2. Then, through the setting of the heat dissipation structure 5, the internal temperature of the housing 1 can be quickly cooled down in two ways, which improves the flexibility and practicality during use. Furthermore, through the setting of the housing 1 and the explosion-proof protection structure 4, the pneumatic actuator body 3 is explosion-proof while buffering the impact of an explosion.
