Description

Technical Field

[0001] This utility model relates to the field of special gas cabinet protection technology, specifically a protective structure for a multi-channel intelligent switching electronic special gas cabinet. Background Technology

[0002] In high-end industrial fields such as semiconductor manufacturing, photovoltaic production, and precision electronics, specialty gases are indispensable raw materials for many critical process steps. Multi-channel intelligent switching electronic specialty gas cabinets, as core equipment in centralized gas supply systems, play a crucial role in safely and stably storing various high-purity or hazardous specialty gases. They automatically and precisely switch and transport these gases between different channels according to process requirements, thereby ensuring the efficiency and product quality of continuous production. However, the gases handled by these cabinets often possess dangerous characteristics such as high pressure, flammability, explosiveness, corrosiveness, or toxicity. Leaks caused by equipment aging, seal failure, or improper operation can easily lead to serious safety accidents such as fires, explosions, or poisoning. Therefore, designing a specialized, efficient, and reliable protective structure for such critical equipment is essential for real-time risk monitoring, suppressing initial fires, and preventing the spread of disasters. This is crucial for ensuring personnel safety, protecting expensive production equipment and assets, and maintaining the continuous and stable operation of the production environment.

[0003] However, in existing technologies, the nozzle structure used to spray fire extinguishing materials is usually fixed and cannot be adjusted according to the location of the fire source, resulting in low fire extinguishing efficiency and serious material waste. At the same time, existing technologies lack active purification functions for the environment inside the cabinet and multi-level safety interlocking mechanisms. The overall protection system has problems of delayed response and single protection methods, making it difficult to cope with the complex and ever-changing safety risks of electronic special gas cabinets. Utility Model Content

[0021] 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.

[0022] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0023] A protective structure for a multi-path intelligent switching electronic special gas cabinet includes a special gas cabinet 101. An arc-shaped cover 102 is bolted to the top surface of the special gas cabinet 101. A sphere 103 is rotatably installed inside the arc-shaped cover 102. One side of the sphere 103 is connected to the arc-shaped cover 102 and a nozzle 104 is fixedly installed at the through point. The other end of the nozzle 104 is threaded on the outside and faces the inside of the special gas cabinet 101. A high-pressure hose 105 is fixedly installed on the side of the sphere 103 opposite to the nozzle 104. The high-pressure hose 105 consists of two sections, and a solenoid valve 106 is fixedly installed between the two sections of the high-pressure hose 105. The other end of the high-pressure hose 105 is fixedly installed at the discharge end of a high-pressure tank 107.

[0024] The above scheme utilizes a special gas holder as the main structure to provide the installation foundation and sealed space for the entire protection system. Bolts securely and detachably connect the arc-shaped cover to the top surface inside the special gas holder. The arc-shaped cover forms a sealed cavity to accommodate and support the spherical component. The rotation of the sphere within the cavity provides omnidirectional adjustment capability for the nozzle's spray angle. The nozzle guides the extinguishing material to a specific area inside the special gas holder. The threaded structure on its outer side provides an interface for the installation of extension pipes or adapters. A flexible extinguishing material delivery channel is established between the high-pressure tank and the movable parts via a high-pressure hose. The controlled release of the extinguishing material is achieved by opening and closing the high-pressure hose passage using a solenoid valve. The high-pressure tank stores and provides sufficient extinguishing material for the firefighting operation.

[0025] In this embodiment, preferably, two circulating air ducts 108 are opened on the bottom surface of the special gas cabinet 101 adjacent to the side of the enclosing arc-shaped cover 102, and a temperature sensor 109 is installed through the side of the special gas cabinet 101 adjacent to the circulating air ducts 108.

[0026] The above scheme provides a channel for forced air circulation by opening a circulating air duct on the bottom of the special gas holder, and uses a temperature sensor installed adjacent to the circulating air duct to monitor the internal ambient temperature of the special gas holder in real time to collect key early warning signals.

[0027] In this embodiment, preferably, a smoke sensor 110 is installed through the other side of the special gas cabinet 101 adjacent to the circulating air duct 108. A cabinet door 111 is installed at the opening of the special gas cabinet 101 via a hinge, and an explosion-proof window 112 is installed on the cabinet door 111 via a hinge.

[0028] The above scheme uses a smoke sensor installed adjacent to the circulating air duct to monitor the concentration of smoke particles inside the special gas cabinet in real time to collect fire detection signals. The cabinet door allows for the opening and closing of the main body opening of the special gas cabinet. The explosion-proof window provides a viewing window for observing the situation inside the cabinet when the door is closed. Its integrated wire mesh structure also plays a role in explosion protection.

[0029] In this embodiment, preferably, a protective box 113 is fixedly installed on the top of the special gas cabinet 101, a display screen 114 is installed through the protective box 113 on the side facing the door, and an emergency stop switch 115 is installed through the protective box 113 on the side adjacent to the display screen 114.

[0030] The above solution provides a centralized installation and protection space for external control and display components through a protective box, displays the system status and monitoring data to operators in real time through a display screen, and provides users with a physical operation interface to manually trigger a complete system shutdown in an emergency through an emergency switch.

[0031] In this embodiment, preferably, the protective box 113 has a heat dissipation groove 116 on the side away from the emergency stop switch 115, and a box cover 117 is bolted to the top of the protective box 113. An alarm light 118 is installed through one side of the top of the box cover 117.

[0032] The above scheme uses heat dissipation slots to form air convection channels, providing a way for heat generated by the internal components of the protective box, especially the electronic circuit boards, to dissipate. The box cover provides sealing and protection for the top of the protective box, and the bolt connection facilitates maintenance and operation. The alarm light emits a highly visible flashing signal to alert on-site personnel when the system issues a warning or alarm.

[0033] In this embodiment, preferably, a circuit board protective cover 119 is bolted to the inside of the protective box 113 opposite to the heat dissipation slot 116, and a filter 120 is bolted to the inside of the protective box 113 opposite to the circulating air slot 108.

[0034] The above solution provides additional protection against physical contact and dust for the dedicated circuit board through a circuit board protective cover, and purifies the air introduced from the circulating air duct through a filter to decompose or adsorb specific harmful gases that may be present in the special gas cabinet.

[0035] In this embodiment, preferably, a high-pressure tank 107 is installed inside the protective box 113 adjacent to the filter 120 by clamps, and the dedicated circuit board inside the circuit board protective cover 119 is connected to the corresponding connectors of the alarm light 118, emergency stop switch 115, smoke sensor 110, temperature sensor 109, and solenoid valve 106 by flexible wires.

[0036] The above solution securely installs the high-pressure tank in a designated position inside the protective box using clamps. A dedicated circuit board receives and processes signals from various sensors and coordinates the operation of all electrical control components, such as solenoid valves and alarm lights. Flexible wires establish reliable electrical connections between the dedicated circuit board and dispersed components such as solenoid valves, alarm lights, emergency stop switches, smoke sensors, and temperature sensors.

[0037] In this embodiment, the protective structure of a multi-path intelligent switching electronic special gas cabinet 101 is such that, during use, the temperature sensor 109 and the smoke sensor 110 integrated inside the special gas cabinet 101 collect environmental data in real time and transmit the signals to a dedicated circuit board installed in the circuit board protective cover 119 inside the protective box 113. This circuit board is a core processing unit customized according to the sensor functions and control logic.

[0038] When an abnormal temperature rise and abnormal smoke concentration simultaneously occur inside the special gas holder 101 for any reason, the dedicated circuit board determines that a dangerous situation of open flame combustion has occurred. The circuit board then issues a command to activate the solenoid valve 106, which controls the opening and closing of the high-pressure hose 105. After the solenoid valve 106 opens, the extinguishing material stored in the high-pressure tank 107 flows under pressure through the high-pressure hose 105, through the omnidirectionally rotatable sphere 103, and finally is sprayed into the special gas holder 101 from the threaded nozzle 104. The nozzle 104, with the help of the rotation function of the sphere 103 within the arc-shaped cover 102, can flexibly adjust the direction of the nozzle, thereby accurately targeting specific locations inside the holder prone to fire for extinguishing operations, greatly improving the utilization efficiency of the extinguishing material and the targeting of fire suppression. The threaded structure on the outside of the nozzle 104 also allows for the addition of bends or extension pipes, further expanding the fire suppression coverage area.

[0039] If only one of the sensors, temperature sensor 109 or smoke sensor 110, detects an abnormal signal, the dedicated circuit board determines it to be a potential risk or warning state. At this time, the circuit board will trigger the alarm light 118 mounted on the top of the cover 117, causing it to flash and buzz, issuing a visual and auditory alarm to the on-site operators. The operators can then observe the interior of the special gas cabinet 101 through the explosion-proof window 112, which features an integrated wire mesh structure inside the glass and is installed on the cabinet door 111. This explosion-proof window 112 provides an observation window while ensuring a high level of explosion-proof safety. If necessary, the operators can also trigger the emergency stop switch 115, which runs through the protective box 113. This switch sends a signal to the dedicated circuit board, which executes the emergency cut-off logic, quickly disconnecting the gas and electrical connections inside the special gas cabinet 101, achieving complete safety isolation. This emergency stop function will also be activated simultaneously during the entire firefighting process in the event of a fire.

[0040] To maintain a stable and clean gas environment inside the special gas holder 101, a circulating air duct 108 is provided on the bottom surface of the special gas holder 101, which works in conjunction with the filter 120 installed inside the protective box 113. Powered by an external fan, the air inside the special gas holder 101 is forced to circulate, and the exhaust gas or suspicious gas passing through is adsorbed, decomposed, or purified by the filter 120. The filter 120 can be selected according to the type of gas actually used in the special gas holder 101, such as a filter element specifically designed for decomposing hydrogen, thereby actively eliminating the potential for the accumulation of specific hazardous gases and enhancing the system's deep protection capability against filterable gases. For gases that cannot be processed by the filter 120, the system still relies on the monitoring network of temperature sensors 109 and smoke sensors 110, as well as the aforementioned fire extinguishing and emergency shutdown mechanisms, to provide core protection.

[0041] Throughout the system's operation, the heat dissipation slots 116 on the side wall of the protective enclosure 113 continuously provide necessary ventilation and heat dissipation for the dedicated circuit boards and other electronic components inside the circuit board protective cover 119, ensuring the stable operation of the control core. Simultaneously, the display screen 114, mounted throughout the protective enclosure 113, continuously displays real-time monitoring data and system status information from various sensors, providing operators with comprehensive human-machine interaction and decision support.

[0042] This protective structure, through the efficient collaboration of multiple subsystems such as sensor monitoring, intelligent judgment, active fire suppression, emergency isolation, environmental purification and status monitoring, constructs a multi-layered and intelligent safety protection system, which significantly improves the overall safety and reliability of the electronic special gas cabinet 101 in the face of fire risks and gaseous hazards.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
