[0021] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0022] The intelligent hazardous chemical storage cabinet of the present application includes a cabinet body 1, a left door 2 and a right door 3 arranged on the same side of the cabinet body 1, and a top box 4 fixed above the cabinet body 1 and relatively independent of the cabinet body.

[0023] like Figures 1 to 4 As shown, a vent 11 is provided on each side plate of the cabinet body 1, and a ventilation and flame arrester is provided in each vent 11. The vent 11 has a certain effect of circulating and evacuating the gas in the cabinet when the fan is not working. When the cabinet fan is working, it can quickly replenish the air in the cabinet and circulate and evacuate the gas in the cabinet in time. The ventilation and flame arrester can prevent the flame from entering and causing the fire hazard, and strengthen the fire prevention ability of the cabinet. A gas / VOC transmitter 12 and a temperature and humidity transmitter 13 are provided on the cabinet body 1. The gas / VOC transmitter 12 and a temperature and humidity transmitter 13 detect and obtain gas and temperature and humidity data in real time and transmit the data to the automatic control system. A leakage tank 14 is provided at the bottom of the cabinet body 1 to prevent the stored liquid items from leaking and causing secondary environmental pollution. In addition, an acid and alkali resistant coating is coated on the inner wall of the cabinet body 1, and there is no need to make an additional liner. The production efficiency is high, the fire prevention performance is good, and more storage space is saved for customers.

[0024] The top box 4 includes a touch screen 41 integrated with an automatic control system, which is embedded in the surface of the top box 4. The touch screen 41 is electrically connected to the gas / VOC transmitter 12, the temperature and humidity transmitter 13 and the ventilation and flame arrester 11. The touch screen 41 obtains the data obtained by the gas / VOC transmitter 12 and the temperature and humidity transmitter 13 and controls the operation of the gas / VOC transmitter 12, the temperature and humidity transmitter 13 and the ventilation and flame arrester 11. The operator can directly set or modify the setting data of the above-mentioned devices on the touch screen 41 and can display the data transmitted by the above-mentioned devices in real time to achieve the purpose of intelligent control. In addition, the automatic control system further includes a CAS material management unit, which is used to visually manage the materials stored in the cabinet body, making the use and storage of materials more reasonable, convenient and safe.

[0025] like Figure 2 and Figure 4 As shown, the top box 4 is provided with an air outlet 42. One end of a ventilation pipe 5 passes through the air outlet 42 and is connected to the vent 11 at the upper end of the cabinet body 1. The ventilation pipe 5 is made of metal and has good fireproof performance. The top box 4 is provided with an audible and visual alarm 43, a power supply 44, a relay 45 and a fan 46. The fan 46 is connected to the other end of the ventilation pipe 43. The air outlet 461 of the fan 46 passes through the outer shell of the top box 4 and extends out of the top box 4. The user can easily connect the external exhaust duct. The fan 46 is connected to the cabinet body 1 and the outside through the ventilation pipe 5, avoiding the problem of reduced fireproof performance of the whole cabinet product caused by the need to set ventilation holes through the top box in the existing design. The audible and visual alarm 43 is electrically connected to the automatic control system and is controlled by the automatic control system and the touch screen. The power supply 44 and the relay 45 supply power to each component.

[0026] In addition, the present application adopts a three-point linkage latch 6 that prevents the generation of electric sparks and has the functions of locking, no static sparks and three-point linkage. The three-point linkage latch includes sub-door latches arranged at the middle, top and bottom of the right cabinet door, which are controlled by a locking rod, and a lock body that controls the movement of the locking rod. The lock body is one or two of a mechanical panel lock, a Bluetooth lock, an electronic password lock, and a mechanical padlock. The lock body can also adopt a panel lock with an electronic lock core. While realizing the three-point linkage of the cabinet door and the double lock of two people, it can also realize the traceability management of the cabinet door switch, making the management more convenient and safer. The three-point linkage flat lock can be optionally equipped with an upgraded Bluetooth smart cloud lock core, which can realize the smart cloud lock positioning, remote permission setting and usage record management of the storage cabinet.

[0027] In addition, the outer side of the cabinet body of the present application is sprayed with different colors according to the physical properties of the stored objects, wherein: chemical liquids with a flash point of less than 37.8°C are flammable liquids, and the color of the outer side of the cabinet body is yellow; chemical liquids with a flash point of ≥37.8°C are flammable liquids, and the color of the outer side of the cabinet body is red; when storing weakly corrosive chemicals, the color of the outer side of the cabinet body is blue; when storing toxic chemicals and liquids, the color of the outer side of the cabinet body is white; when storing insecticides or pesticide liquids, the color of the outer side of the cabinet body is green; when storing various acid and alkali liquids and solvents in laboratory chemical reagents, the color of the outer side of the cabinet body is gray, light gray and silver.

[0028] In addition, such as Figure 2 As shown, support frames 15 are fixed on both sides of the cabinet body, and a plurality of layer boards 16 are provided on the corresponding support frames 15, and the height of the layer boards 16 can be adjusted as required.

[0029] See also Figure 1 If the hazardous chemicals stored in the cabinet body 1 leak, the gas / VOC transmitter 12 will detect the leaked gas or VOC. When the spatial concentration reaches the set warning value, the gas / VOC transmitter 12 will send a signal to the automatic control system, and the automatic control system will start the fan 46 to exhaust the leaked gas in the cabinet body 1 to the outside and reduce the gas concentration. At the same time, the sound and light alarm 43 will be started to sound and light alarm. The fan 46 exhausts air to the outside. When the gas or VOC concentration in the cabinet body 1 drops to the set threshold, the fan 46 stops running and the sound and light alarm 43 stops sound and light alarm. The control of this type of program can be achieved through existing technologies. The automatic control system can also realize the setting of thresholds.

[0030] The gas / VOC transmitter 12 of the present application is connected to an automatic control system, and the automatic control system displays the gas or VOC concentration data collected by the gas / VOC transmitter 12 on the touch screen 41 so that the user can view the gas or VOC concentration value in the cabinet body 1 in real time.

[0031] See Figure 3 The temperature and humidity transmitter 43 of the present application is also connected to the automatic control system, and the automatic control system displays the temperature and humidity data detected by the temperature and humidity transmitter 43 on the touch screen 12, so that the user can view the temperature and humidity values ​​in the cabinet in real time.

[0032] In addition, the present application also includes a backend cloud server, which is connected to the automatic control system via a network to achieve data interaction or remote control.

[0033] This application can automatically monitor, alarm and take dangerous situation handling measures, and has excellent properties such as high strength, effective leakage prevention, and reliable fire prevention.
