[0002] Explosion-proof positive pressure devices are safety devices designed for hazardous environments. By maintaining internal pressure higher than external pressure, they effectively prevent flammable and explosive gases or dust from entering the equipment, thereby reducing the risk of explosion. They are mainly used in industries such as petroleum, natural gas, chemicals, pharmaceuticals, and mining to protect electrical equipment, control systems, and analytical instruments from external explosive threats. Their working principle is simple and critical, ensuring the safe operation of equipment in hazardous environments, thereby ensuring production and personnel safety. The application of explosion-proof positive pressure devices not only improves the safety and reliability of equipment, but also plays a key role in various industries and specific applications, providing operators with a safe working environment and reliable equipment protection.

[0028] like Figure 1 and Figure 2 As shown, an integrated explosion-proof positive pressure controller includes a controller body 1, and a protective structure 2 is provided on the outside of the controller body 1, the protective structure 2 includes a movable plate structure 21 placed above the controller body 1, the movable plate structure 2 is provided with an outer shell 22 which is sleeved on the outside of the controller body 1 and inserted by the movable plate structure 2, a plurality of sliding plates 23 are provided on the movable plate structure 21, the outer shell of the controller body 1 is provided with a heat sink 11 which is placed inside the outer shell 22, the heat sinks 11 are staggered and distributed on the outside of the controller body 1, the heat sinks 11 are fixedly connected by bolt structures 12, and earrings 111 are fixedly connected on both sides of the heat sink 11 below the controller body 1.

[0029] In this embodiment, the protection of the controller body 1 is achieved by providing a protective structure 2 placed on the outside of the controller body 1. However, after being hit from the outside, the controller body 1 uses the movable plate structure 21 above itself to achieve buffering inside the outer shell 22. At the same time, the transverse sliding plate 23 buffers the transmission line to prevent it from falling off due to excessive force, thereby ensuring its own stable installation. At the same time, the movable plate structure 2 is pressed on top of the controller body 1 to make the connection more stable. The heat sink 11 effectively achieves heat conduction to the controller body 1 while reinforcing the connection stability.

[0030] like Figure 3 , 4 As shown in Figures 5 and 6, the outer shell 1 is provided with a groove 24 penetrating through one side of the plate body thereof, the inside of the groove 24 is connected to a limit plate 26 through evenly distributed springs 25, a movable plate 27 sleeved on the outside of the sliding plate 23 is fixedly connected between the limit plates 26, the thickness of the limit plate 26 is smaller than that of the movable plate 27, a plurality of evenly distributed through grooves 271 corresponding to the sliding plate 23 are provided inside the movable plate 27, a transverse plate 273 fixedly connected to the sliding plate 23 is fixedly connected inside the through grooves 271 through symmetrically distributed tension springs 272, the sliding plate 23 is provided with a mounting hole 274 corresponding to the transmission line and penetrating the sliding plate 23, a combing plate 112 penetrating through the transmission line is provided above the controller body 1, and a limit member 14 corresponding to the mounting hole 274 is connected above the combing plate 112 through a limiting hole 13.

[0031] In this embodiment, the spring 25 inside the groove 24 is connected to the limit plate 26, so that the entire device can absorb the impact force through the compression and rebound of the spring when subjected to external force, thereby protecting the internal controller and other components from damage; the limited plate 26 and the movable plate 27 are used in conjunction with each other, and the movable plate 27 is connected to the sliding plate 23 through the through groove 271 and the tension spring 272, making the entire structure more compact and stable, and preventing the parts from loosening or falling off due to vibration or impact during use; heat dissipation and reinforcement effect: the heat dissipation plates 11 are staggered and distributed on the outside of the controller body 1, which not only helps the device to The heat dissipation of the equipment is prevented from overheating, and a fixed connection is achieved through the bolt structure 12, which enhances the mechanical strength and stability of the entire device; Transmission line protection: The design of the mounting hole 274 and the limiter 14 on the sliding plate 23 enables the transmission line to be stably fixed on the combing plate 12 above the controller body 1, preventing the transmission line from falling off due to external force, thereby ensuring the stability of signal and power transmission; The design of the movable plate 27 and the through groove 271 makes disassembly and assembly more convenient, and the equipment can be quickly maintained and repaired without affecting other components, thereby improving the maintainability of the equipment.

[0032] When using:

[0033] 1. Enhanced protection performance: The protective structure 2 outside the controller body includes a movable plate structure 21 and an outer shell 22. When the device is hit by an external impact, the movable plate structure 21 provides a buffering effect to reduce the direct damage to the internal controller. The horizontally sliding sliding plate 23 further buffers the transmission line to prevent it from falling off due to excessive force, thereby ensuring the stable installation of the device.

[0034] 2. Heat dissipation and reinforcement: The heat sink 11 is closely distributed around the controller body, and an effective heat conduction mechanism is used to prevent the device from overheating. At the same time, the bolt structure 12 is used to strengthen the fixation of the heat sink, thereby improving the mechanical strength and stability of the entire device.

[0035] 3. Earthquake-resistant design: The groove 24 inside the outer shell is connected by evenly distributed springs 25 and limit plates 26. Its structure can absorb impact force through compression and rebound of the spring when facing external force, protecting the controller and other key components from damage.

[0036] 4. Transmission line protection: The design of the mounting hole 274 and the limiter 14 on the sliding plate 23 ensures that the transmission line can be firmly fixed on the combing plate 12 above the controller body, preventing the transmission line from loosening or falling off due to vibration or impact, and ensuring the stability of signal and power transmission.

[0037] 5. Structural stability: The coordinated use of the limit plate 26 and the movable plate 27, through the connection of the through slot 271 and the tension spring 272, makes the entire device structure more compact and stable, prevents loosening or falling off during operation, and ensures reliable operation of the device.

[0038] 6. Convenient maintenance: The design of the movable plate 27 and the through slot 271 makes the disassembly and assembly of the equipment more convenient. Without affecting other components, the equipment can be quickly maintained and repaired, thereby improving the maintainability of the overall equipment and reducing downtime and maintenance costs.

[0039] In general, the present invention effectively improves the protection performance, thermal management capability, seismic resistance, and convenience of operation and maintenance of the explosion-proof positive pressure controller through multiple structural designs. It is suitable for various complex and dangerous industrial environment applications, greatly ensures the safe and reliable operation of the equipment, and reduces maintenance costs and operational risks.

[0040] Although the present invention has been disclosed as above in the form of a preferred embodiment, it is not intended to limit the present invention. Anyone familiar with this technology can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the claims.
