Description

Technical Field

[0001] The utility model relates to the technical field of storage equipment, in particular to a novel explosion-proof cabinet. Background Art

[0002] In a broad sense, explosion-proof cabinets are equipment used to store flammable and explosive items. With the advancement of industrial technology, the functions of explosion-proof cabinets have become more and more complete. For example, my country's authorized patent with patent number "202222891484.6" and patent name "explosion-proof cabinet" states that "this solution can avoid the problem of excessive storage of dangerous items in the explosion-proof cabinet, resulting in dangerous situations in the explosion-proof cabinet."

[0003] As can be seen from the above, although the comparative patent has achieved the technical effect of the invention described therein to a certain extent, it is limited by the structure and, like other explosion-proof cabinets in the field, still has the following problems that need to be improved. Specifically, when the items stored in the explosion-proof cabinet burn and the temperature rises, toxic and harmful gases leak, gas leakage causes the pressure in the sealed cabinet to increase, liquid leaks, etc., due to the lack of a practical reminder device, when the above situation occurs, it is impossible to promptly remind nearby staff to deal with it, and it is impossible to automatically extinguish the fire. Therefore, there is a probability of the fault expanding. In summary, it is particularly necessary to provide an explosion-proof cabinet that not only has the function of storing items, but also can monitor the items stored inside in real time, can automatically remind staff when abnormalities and fires occur, and can automatically extinguish fires. Utility Model Content

[0004] In order to overcome the drawbacks of existing explosion-proof cabinets due to structural limitations as described in the background, the utility model provides an explosion-proof cabinet body, which can monitor in real time whether the stored items are experiencing excessive temperature rise, combustion, leakage, increased pressure, or leakage of toxic and harmful gases during application, and can promptly prompt nearby staff to conduct inspections when abnormalities occur, and can automatically extinguish fires in case of fire, thereby preventing the expansion of faults and achieving better safety effects.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A novel explosion-proof cabinet comprises an explosion-proof cabinet body, a temperature switch, a fire detection module, a pressure detection mechanism, a liquid leakage detection mechanism, a combustible gas leakage detection module, a solenoid valve, and a water pipe; the characteristic is that it also has an alarm mechanism; there are multiple water pipes, the multiple water pipes are installed together, and the multiple water pipes are interconnected, the multiple water pipes are installed with water inlet pipes, and the multiple water pipes are installed in the upper part of the explosion-proof cabinet body, one end of the solenoid valve is connected to one end of the water inlet pipe, and the other end of the solenoid valve is connected to the tap water pipe; the temperature switch, the fire detection module, the pressure detection mechanism, the liquid leakage detection mechanism, the combustible gas leakage detection module, and the alarm mechanism are installed in a component box, and the component box is installed in the explosion-proof cabinet body; the signal input end of the alarm mechanism is electrically connected to the signal output end of the temperature switch, the fire detection module, the pressure detection mechanism, the liquid leakage detection mechanism, and the combustible gas leakage detection module, and the trigger output end of the fire detection module is electrically connected to the power input end of the solenoid valve.

[0007] Furthermore, the solenoid valve is a normally closed valve core solenoid valve.

[0008] Furthermore, the alarm mechanism includes an electrically connected diode and an alarm, and the positive power input terminal of the alarm is connected to the cathode of the diode.

[0009] Furthermore, the lower ends of the plurality of water pipes are respectively provided with a plurality of spray holes.

[0010] Furthermore, the pressure detection mechanism includes a cylinder, a power switch, and a piston. The front end of the cylinder is an open structure and the rear end is a closed structure. The power switch is installed at the rear end of the cylinder with its button facing forward. The piston is movably sleeved in the front end of the cylinder and its rear end is in contact with the front side of the button of the power switch.

[0011] Compared with the prior art, the utility model has the following beneficial effects: the utility model is based on an explosion-proof cabinet body whose cabinet door can be closed. In application, the temperature switch, fire detection module, pressure detection mechanism, liquid leakage detection mechanism, and combustible gas leakage detection module can monitor in real time whether the stored items have excessive temperature rise, combustion, liquid leakage, increased pressure, or toxic and harmful gas leakage. When an abnormality occurs, the alarm mechanism can prompt the nearest staff to conduct an inspection in time, and the electromagnetic valve can be opened in case of fire, and tap water can be sprayed out through the spray hole at the lower end of the water pipe to automatically extinguish the fire, thereby preventing the expansion of faults and achieving better safety effects. In summary, the new model has good application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 , 2 As shown in the figure, the new explosion-proof cabinet includes an explosion-proof cabinet body 1, a power supply mechanism T1, a temperature switch D1, a fire detection module T3, a pressure detection mechanism, a liquid leakage detection mechanism T2, a combustible gas leakage detection module T, a solenoid valve FD, and a water pipe 2; it also has an alarm mechanism 3; there are three water pipes 2, the left and right ends of the three water pipes 2 are welded together at a distance from each other, and the three water pipes 2 are interconnected, and the upper end of a rear end water pipe 2 is vertically welded with a water inlet pipe 21 that is interconnected with the inside thereof, and the outer sides of the three water pipes 2 are respectively welded to the upper part of the explosion-proof cabinet body 1, The upper part of the water inlet pipe 21 (the outer side of the upper part of the water inlet pipe 21 and the contact part of the upper end of the explosion-proof cabinet body 1 are sealed and welded) is located outside the upper end of the explosion-proof cabinet body 1, one end of the solenoid valve FD is connected to the upper end of the water inlet pipe 21 via a thread, and the other end of the solenoid valve FD is connected to the tap water pipe via a pipeline; the power supply mechanism T1, the temperature switch D1, the fire detection module T3, the pressure detection mechanism, the liquid leakage detection mechanism T2, the combustible gas leakage detection module T, and the alarm mechanism 3 are sealed and installed in the component box 4, and the component box 4 is installed in the upper rear end of the explosion-proof cabinet body 1 (the height is higher than the water pipe height).

[0016] Figure 1 , 2As shown, the solenoid valve FD is a normally closed valve core solenoid valve (2W). The alarm mechanism includes a diode VD1 and an alarm B1 connected by circuit board wiring, and the positive power input end of the alarm B1 is connected to the negative pole of the diode VD1. The lower ends of the three water pipes are horizontally spaced at a certain distance and have multiple spray holes 22. The pressure detection mechanism includes a cylinder 51, a power switch D2 (normally open contact), and a piston 52. The front end of the cylinder 51 is an open structure and the rear end is a closed structure. The rear side end of the power switch D2 is glued to the middle of the rear end of the cylinder 51 with its button facing forward. The piston 52 is movably sleeved in the front end of the cylinder 51 and its rear end contacts the front side of the button of the power switch D2. The temperature sensing head of the temperature switch D1, the detection head of the fire detection module T3, the front end of the cylinder 51 of the pressure detection mechanism, and the detection head of the combustible gas leakage detection module T are respectively located outside the front outer end of the component box 4, and the detection head of the liquid leakage detection mechanism T2 is located at the rear side of the lower end of the explosion-proof cabinet body 1. The power input terminals 1 and 2 of the power supply mechanism T1 are connected to the two poles of the AC 220V via wires, respectively; the power output terminals 3 and 4 of the power supply mechanism T1 are connected to the power input terminal of the temperature switch D1, the power input terminals 1 and 2 of the fire detection module T3, the power input terminal of the power switch D2 of the pressure detection mechanism, the power input terminals 1 and 2 of the liquid leakage detection mechanism T2, and the power input terminals 1 and 2 of the combustible gas leakage detection module T via wires, respectively; the positive power input terminal of the signal input terminal sounder B1 of the alarm mechanism and the power output terminal of the temperature switch D1, the power output terminal 3 of the fire detection module T3 (connected to the positive pole of the diode VD1 via wires), the power output terminal of the power switch D2 of the pressure detection mechanism, the power output terminal 3 of the liquid leakage detection mechanism T2, and the power output terminal 3 of the combustible gas leakage detection module T are connected via wires; the power output terminal 3 of the fire detection module T3 and the positive power input terminal of the solenoid valve FD are connected via wires. The negative power input terminal of the solenoid valve FD and the buzzer B and the negative power output terminal 4 of the power supply mechanism T1 are connected via a wire.

[0017] Figure 1 , 2As shown, after the AC 220V power supply enters the power input end of the power supply mechanism T1, the power output end of the power supply mechanism T1 outputs a 12V DC power supply to enter the temperature switch D1, the fire detection module T3, the power switch D1 of the pressure detection mechanism, the liquid leakage detection mechanism T2, and the power input end of the combustible gas leakage detection module T, and the above mechanisms are powered on. When the temperature inside the explosion-proof cabinet body 1 is appropriate (for example, below 50°C), the power output end of the temperature switch D1 does not output power to enter the power input end of the buzzer B1, and the buzzer B1 will not be powered on to sound; when the temperature inside the explosion-proof cabinet body 1 is too high (for example, at the initial stage of a fire of items stored in the cabinet, the temperature inside the cabinet exceeds 50°C), the power output end of the temperature switch D1 (two normally open contacts are closed) outputs power to enter the power input end of the buzzer B1, and the buzzer B1 will be powered on to sound to remind the nearby staff. After the fire detection module T3 is powered on, when there is no fire in the explosion-proof cabinet body 1, the power output terminal 3 pin of the fire detection module T3 does not output power to the power input terminal of the alarm B1, and the alarm B1 will not be powered on and sound; when a fire occurs in the explosion-proof cabinet body 1, the power output terminal 3 pin of the fire detection module T3 outputs power through the diode VD1 to enter the power input terminal of the alarm B1 in a unidirectional manner, and the alarm B1 will be powered on and sound to remind the nearby staff. After the pressure detection mechanism is powered on and works, when the pressure in the cabinet is normal, the internal contacts of the power switch D2 will not be closed, and the corresponding alarm B1 will not be powered on and sound; when the pressure in the cabinet is high (for example, the gas leakage in the stored gas cylinder causes the pressure in the explosion-proof cabinet to increase), the piston 52 moves from the front end to the rear end of the cylinder 51, and the piston 52 presses the power switch D2 button backward, the internal contacts of the power switch D2 will be closed, and the corresponding alarm B1 will be powered on and sound. After the combustible gas leakage detection module T is powered on, when there is no combustible gas leakage in the explosion-proof cabinet body 1, its 3rd pin does not output power to the power input end of the buzzer B1, and the corresponding buzzer B1 will not be powered on and sound; when there is combustible gas leakage in the explosion-proof cabinet body 1 (for example, the valve of the cylinder storing combustible gas is damaged and leaking), its 3rd pin outputs power to the power input end of the buzzer B1, and the corresponding buzzer B1 will be powered on and sound. After the liquid leakage detection mechanism T2 is powered on, when there is no liquid leakage in the explosion-proof cabinet body 1, its 3rd pin does not output power to the power input end of the buzzer B1, and the corresponding buzzer B1 will not be powered on and sound; when there is liquid leakage in the explosion-proof cabinet body 1, its 3rd pin outputs power to the power input end of the buzzer B1, and the corresponding buzzer B1 will be powered on and sound. In the present invention, when the fire alarm B1 in the explosion-proof cabinet body 1 is energized and sounds, the power output from the 3rd pin of the fire detection module T3 will also enter the power input end of the electromagnetic valve FD, and the valve core of the electromagnetic valve FD will be energized to open, so that tap water will be sprayed out through the spray holes at the lower ends of the three water pipes to extinguish the fire. When the fire in the explosion-proof cabinet body 1 is extinguished, the 3rd pin of the fire detection module T3 will no longer output power, so that the electromagnetic valve FD will lose power and close, preventing excessive water from entering the cabinet body and causing waste.Through the above, the utility model is based on an explosion-proof cabinet body with a door that can be closed (used to store and place corresponding articles. If the door of the explosion-proof cabinet body cannot be closed as required, the pressure detection mechanism may not be selected). In application, the temperature switch, fire detection module, pressure detection mechanism, liquid leakage detection mechanism, and combustible gas leakage detection module can monitor in real time whether the stored articles have excessive temperature rise, combustion, liquid leakage, increased pressure, or toxic and harmful gas leakage. When an abnormality occurs, the alarm can be used to prompt the nearby staff to check in time, and in case of fire, the solenoid valve can be opened and tap water can be sprayed out through the spray hole at the lower end of the water pipe to automatically extinguish the fire, thereby preventing the expansion of faults and achieving better safety effects. Figure 2 Among them, the buzzer B is an active continuous sound alarm finished product of model XF-12V; the diode VD1 model is 1N4007; the power supply mechanism T1 is an AC 220V to DC 12V power supply module; the temperature switch D1 is a 50℃ model KSD301 snap-type normally open contact temperature switch; the fire detection module T3 model is JBF5100 (with two power input terminals and one signal output terminal, and the signal output terminal outputs power when a fire is detected); the liquid leakage detection mechanism T2 is a liquid leakage detection module finished product of model gK3C6HJX (with two power input terminals and one signal output terminal, and the signal output terminal outputs power when the detection head detects liquid leakage); the combustible gas leakage detection module T is a combustible gas leakage detection sensor module of model TPM-1.8TV2.0 (with two power input terminals and one signal output terminal, and the signal output terminal outputs power when a fire is detected).

[0018] It should be understood that although the present specification is described according to the implementation mode, the implementation mode does not only include an independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in the embodiments can also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
