Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further:
As shown in Fig. 1, Fig. 2, a kind of intelligent detecting fire-extinguishing apparatus controlling to start based on PLC temperature comprises the first temperature sensor 1, second temperature sensor 2, PLC temperature control module 3, warning device 4, protected equipment 5, extinguishing device 6, protection zone 7, magnetic valve 8, storage bottle 9, releasing tube 10, fire trace tube 11 and container value 12, protected equipment 5 is preferably cleaner, cleaner is provided with ventilation shaft, air inlet and the air outlet place of cleaner are all provided with corresponding butterfly valve, extinguishing device 6 is arranged on protected equipment 5 around, protection zone 7 is cleaner inside, described in protected equipment 5, the first temperature sensor 1 is arranged on the air inlet of the ventilation shaft of protected equipment 5, described second temperature sensor 2 is arranged on the air outlet of the ventilation shaft of protected equipment 5, described PLC temperature control module 3 for the first temperature signal of receiving the first temperature sensor 1 and transmitting and the transmission of the second temperature sensor 2 the second temperature signal and control alarm unit according to the difference of the first temperature signal and the second temperature signal, the duty of protected equipment 5 and extinguishing device 6.Described alarm unit 4 is audible-visual annunciator.Described extinguishing device 6 comprises releasing tube 10, storage bottle 9, fire trace tube 11, magnetic valve 8 and container value 12, described container value 12 is arranged on the opening of storage bottle 9, described container value 12 is communicated with fire trace tube 11 with releasing tube 10 respectively, described magnetic valve 8 is arranged on the end of fire trace tube 11, described magnetic valve 8 is also electrically connected with PLC temperature control module 3 output, and described storage bottle 9 is for storing extinguishing chemical.The temperature of the fusing of described fire trace tube 11 is 150 DEG C-170 DEG C.
Operation principle of the present utility model: the temperature at two ends imported and exported by the first temperature sensor 1 and the second temperature sensor 2 for gathering cleaner ventilation shaft, and the temperature data detected is transferred to PLC temperature control module 3 place.PLC temperature control module 3 is by certain differential temperature logical calculated, export corresponding control signal, PLC temperature control module 3 has three differential temperature controls, differential temperature between first temperature sensor 1 and the second temperature sensor 2 reaches the setting of one-level differential temperature when being greater than 5 DEG C, now output signal warning device 4 is carried out temperature that alert notice factory management personnel note protected equipment 5; Differential temperature between first temperature sensor 1 and the second temperature sensor 2 reaches the setting of secondary differential temperature when being greater than 20 DEG C, now PLC temperature control module 3 exports the protected equipment 5 of coordinated signals signal at stop, that is to say and close the blower fan of protected equipment 5 and the butterfly valve of air inlet and air outlet, prevent temperature from being raised further by the operation of equipment and causing fire; Differential temperature between first temperature sensor 1 and the second temperature sensor 2 reaches three grades of differential temperature settings when being greater than 35 DEG C, PLC temperature control module 3 exports coordinated signals signal and opens magnetic valve 8, pressure now in fire trace tube 11 declines thereupon, container value 12 inner chamber low pressure is greater than upper pressure, namely the pressure in bottle group is greater than the pressure in fire trace tube 11, extinguishing chemical promotes to open container value 12, sprays from releasing tube 10.Under running into extreme case; time electronic equipment is malfunctioning; now based on the physical detecting of fire trace tube 11; when environment temperature reaches 150 DEG C-170 DEG C; fire trace tube 11 melts, and then automatically starts extinguishing device 6, carrys out spray fire extinguishing agent by releasing tube 10; put out a fire in protection zone 7, prevent the loss causing factory because of the malfunctioning of electronic equipment.
