Compared to existing technology, the beneficial effects of the utility model are: the temperature controller 1, by arranging Multistage Control realizes three grades of protection, both cleaner can have been made normally to work as much as possible, also carried out alarm to the contingent condition of a fire or start extinguishing device simultaneously putting out a fire.2, in extinguishing device, introduce fire trace tube, when temperature controller cannot normally work in extreme situations, the physical detecting form by fire trace tube opens extinguishing device, further ensures the normal work of extinguishing device.3, detected by the intake stack of spark detector to cleaner, control cleaner when finding spark and quit work and report to the police, play the effect of duplicate protection cleaner.

Accompanying drawing explanation

Fig. 1 is the function structure chart of the defense controls device based on temperature and spark detection of the present utility model.

Fig. 2 is the preferred structure figure of extinguishing device of the present utility model.

Embodiment

Below, by reference to the accompanying drawings and embodiment, the utility model is described further:

With reference to figure 1 and Fig. 2, a kind of defense controls device based on temperature and spark detection, comprising: temperature sensor 1, temperature controller 2, alarm module 3, extinguishing device 4 and spark detector 6.The inside of a cleaner 5 is located at by temperature sensor 1, cleaner 5 has intake stack and wind pipe, the porch of intake stack is located at by spark detector 6, a fire insulation valve is respectively equipped with in the exit of intake stack and the porch of wind pipe, cleaner 5 also has switch module, the switch module of temperature sensor 1, alarm module 3, extinguishing device 4 and cleaner 5 is electrically connected with temperature controller 2 respectively, and described spark detector 6 is electrically connected with the switch module of cleaner 5 and alarm module 3 respectively.

Alarm module 3 is preferably audible-visual annunciator, can sound and light simultaneously, reaches the effect of warning of reporting to the police.Extinguishing device 4 comprises releasing tube 41, storage bottle 42, solenoid valve 43, fire trace tube 44 and container value 45, container value 45 is arranged on the opening of storage bottle, container value 45 is also communicated with fire trace tube 44 with releasing tube 41 respectively, solenoid valve 43 is arranged on the end of fire trace tube 44, and solenoid valve 43 is also electrically connected with temperature controller 2.Wherein, releasing tube 41 and fire trace tube 44 are all located at the inside of cleaner 5.The model of temperature controller 2 is preferably E5AC-RX3ASM-808.

Principle of work of the present utility model is as follows: carry out temperature sensing by temperature sensor 1 and be sent to by temperature signal in temperature controller 2, temperature controller 2 is provided with three grades of temperature thresholds, when temperature signal reaches first order temperature threshold, then send alerting signal to alarm module 3, notify that managerial personnel should be noted that the temperature in this region; When temperature signal reaches second level temperature threshold, switch module then to cleaner 5 sends shutdown signal, switch module is made to perform closing motion, thus the blower fan controlling cleaner 5 quits work, and control fire insulation valve closedown intake stack and wind pipe, prevent cleaner 5 from working on and the possibility of initiation fire generation further, also play simultaneously and cleaner 5 is protected, because be exactly many times cause high temperature because of the malfunction of equipment thus further initiation fire; When temperature signal reaches third level temperature threshold, then represent the inside breaking out of fire of cleaner 5, now need to control extinguishing device 4 to start working, now temperature controller 2 Controlling solenoid valve 43 is opened, and causes the pressure drop in fire trace tube 44, and the inner chamber low pressure of container value 45 is greater than upper pressure, pressure in storage bottle 42 is greater than the pressure in fire trace tube 44, fire extinguishing agent promotes to open container value 45, sprays, reach the object of fire extinguishing from releasing tube 41.

When running into extreme situation, such as temperature controller 2 cannot normally work, now realize fire extinguishing with the physical detecting of fire trace tube 44, such as, when the temperature of fire trace tube 44 reach 150-170 spend time, fire trace tube 44 can melt explosion, thus the pressure drop in fire trace tube 44, cause container value 45 to be opened, make the fire extinguishing agent in storage bottle 42 from releasing tube 41, spray the effect reaching fire extinguishing.Except carrying out temperature sensing to the inside of cleaner 5; also detected by the intake stack of spark detector 6 pairs of cleaners 5; when spark appears in the porch detecting intake stack; then send alerting signal to alarm module 3; send shutdown signal to switch module simultaneously, make switch module perform closing motion, thus the blower fan controlling cleaner 5 quits work; and control fire insulation valve closedown intake stack and wind pipe, play the effect of duplicate protection cleaner 5.

The utility model has the advantage of: the temperature controller 1, by arranging Multistage Control realizes three grades of protection, and cleaner both can have been made normally to work as much as possible, also carry out alarm to the contingent condition of a fire or start extinguishing device simultaneously putting out a fire.2, in extinguishing device, introduce fire trace tube, when temperature controller cannot normally work in extreme situations, the physical detecting form by fire trace tube opens extinguishing device, further ensures the normal work of extinguishing device.3, detected by the intake stack of spark detector to cleaner, control cleaner when finding spark and quit work and report to the police, play the effect of duplicate protection cleaner.

To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of the utility model claim.
