DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention.

[0031] like Figure 1-Figure 9 As shown, the utility model discloses a non-pressurized ultra-fine dry powder fire extinguishing device applied to small industrial and mining vehicles, which comprises:

[0032] The non-pressure storage ultra-fine dry powder fire extinguishing device 1 comprises: a non-pressure storage cylinder 107 storing ultra-fine dry powder fire extinguishing agent inside, a non-pressure storage cylinder lower cover 112 and a non-pressure storage cylinder upper cover 105 arranged at both ends of the non-pressure storage cylinder 107, a PG lock thread head 113 fixed to the non-pressure storage cylinder lower cover 112, and a gas production device connecting line 114 connected to the PG lock thread head 113; a gas production device 110 and a generator fixing part 109 are arranged in the non-pressure storage cylinder lower cover 112; a piston 108 is arranged in the non-pressure storage cylinder 107 at a position adjacent to the generator fixing part 109; the other end of the non-pressure storage cylinder upper cover 105 is connected to the agent release end 102, a diaphragm 104 and a polytetrafluoroethylene gasket 103 are arranged in the non-pressure storage cylinder upper cover 105, and the other end of the agent release end 102 is provided with a release port sealing paper 101;

[0033] A cable-type temperature-sensing detector 5 is laid in the area to be detected of the small mining vehicle; the cable-type temperature-sensing detector 5 is electrically connected to the battery module 3;

[0034] The battery module 3;

[0035] Among them, the non-pressure storage cylinder cover 105 is a cylinder with openings at both ends, a second internal thread 1053 is provided at one end of the non-pressure storage cylinder cover 105, and a first internal thread 1051 is provided at the other end of the non-pressure storage cylinder cover 105, a boss 1052 protruding from the inner wall of the non-pressure storage cylinder cover 105 is provided between the first internal thread 1051 and the second internal thread 1053, and the center of the boss 1052 is a through hole for medicine output; the diaphragm 104 and the polytetrafluoroethylene gasket 103 are abutted against the boss 1052; one end of the medicine release end is provided with an external thread 1021 connected to the first internal thread 1051, and an output hole 1022 is opened on the medicine release end, and the release port sealing paper 101 is abutted against the other end of the medicine release end.

[0036] like Figure 1 , Figure 2 and Figure 4As shown, the non-pressure storage ultra-fine dry powder fire extinguishing device applied to small industrial and mining vehicles described in the utility model lays the cable-type temperature sensing detector 5 in the area to be detected of the small industrial and mining vehicle. When a fire occurs in the area to be detected (protection area), the temperature of the flame causes the space temperature of the protection area to continue to rise and reaches the preset temperature of the cable-type temperature sensing detector 5. The cable-type temperature sensing detector 5 transmits an electrical signal of excessive temperature to the battery plate. The battery plate sends a start-of-work instruction to the gas-generating device 110. The gas-generating device 110 starts to work, and the gas pushes the piston 108. The piston 108 pushes the ultra-fine dry powder fire extinguishing agent inside the non-pressure storage cylinder 107 to move to the other end, and passes through the diaphragm 104, the polytetrafluoroethylene gasket 103, the agent release end and the release port sealing paper 101, and is released to the fire area of ​​the small industrial and mining vehicle to extinguish the fire, discover the fire at the first time, extinguish the fire in time, and reduce the loss of life and property.

[0037] In the above scheme, if Figure 5 The non-pressure storage cylinder 107 includes a medicine chamber 1072, a third internal thread 1073 provided at one end of the non-pressure storage cylinder 107, a first external thread 1071 provided at the other end of the non-pressure storage cylinder 107, and a non-pressure storage fluororubber ring groove 1074 provided at the first external thread 1071;

[0038] The first external thread 1071 is connected to the second internal thread 1053 , and a first fluororubber ring 106 is disposed between the non-pressure storage cylinder 107 and the non-pressure storage cylinder upper cover 105 .

[0039] Both ends of the non-pressure storage cylinder 107 are threadedly connected to other structures, which is convenient for disassembly and replacement, and timely replacement of the ultra-fine dry powder fire extinguishing agent.

[0040] In the above scheme, if Figure 6 As shown, a groove is provided on the outer circumference of the piston 108 , and a piston fluororubber ring 1081 is fixed in the groove. The piston fluororubber ring 1081 is arranged tightly against the inner wall of the non-pressure storage cylinder 107 .

[0041] In the absence of external force, the piston fluororubber ring 1081 is arranged tightly against the inner wall of the non-pressure storage cylinder 107, and the position of the piston 108 remains unchanged; when the gas producing device 110 generates gas, the gas pushes the piston 108 to move from one end of the non-pressure storage cylinder 107 to the other end, thereby releasing the ultra-fine dry powder fire extinguishing agent in the non-pressure storage cylinder 107 from the other end to implement fire extinguishing.

[0042] In the above scheme, if Figure 7 As shown, the generator fixing member 109 includes a hollow structure with two ends opened and a second external thread 1091 arranged on its outer wall;

[0043] The hollow structure includes a fixed space for fixing the gas production device 110 and a gas outlet 1092 . The gas outlet 1092 is a cone structure connected to the fixed space. The gas outlet 1092 is arranged opposite to the piston 108 .

[0044] The generator fixing part 109 can fix the gas generating device 110 inside the non-pressure storage cylinder 107. The gas output by the gas generating device 110 acts on the piston 108, directly pushing the piston 108, and further pushing the ultra-fine dry powder fire extinguishing agent to be released.

[0045] In the above scheme, if Figure 8 As shown, the non-pressure storage cylinder lower cover 112 includes a fourth internal thread 1124 arranged at one end thereof, and the other end of the non-pressure storage cylinder lower cover 112 includes a third external thread 1121 opened on its outer wall, a fifth internal thread 1122 arranged on the inner wall, and a fluororubber ring groove 1123;

[0046] The third external thread 1121 is connected to the third internal thread 1073 , and the fifth internal thread 1122 is connected to the second external thread 1091 .

[0047] In the above solution, the PG lock thread head 113 is threadedly connected to the fourth internal thread 1124 .

[0048] The non-pressure storage cylinder lower cover 112 is threadedly connected to the non-pressure storage cylinder 107 and the generator fixing part 109 through internal and external threads, and the gas production device 110 is connected to the power supply through the PG locking head 113.

[0049] In the above scheme, if Fig. 9 As shown, the battery module 3 includes a battery module housing 301 , an indicator light 302 , a power switch 303 , a dry cell box 304 and a terminal block 305 .

[0050] In the above solution, the device further comprises a manual start button 4 , which is connected to the battery module 3 via a control line 2 .

[0051] When the non-pressurized ultra-fine dry powder fire extinguishing device is in normal working state, when a fire occurs, the staff can manually trigger the device by pressing the manual start button 4, the battery module 3 receives the trigger information, and further triggers the gas generating device 110, the gas generating device 110 generates a large amount of gas, pushes the piston 108, and releases the agent through the agent release end to complete the fire extinguishing process.
