Specifically, according to actual detection needs, install the thermocouple at transformer tank top, for example, a plurality of thermocouple can be installed at transformer tank top according to the matrix distribution mode for detect the condition of a fire of different positions, when certain high temperature, the directional here of control unit control shower nozzle, and then realize accurately putting out a fire.

Example two:

the difference between this embodiment and the first embodiment is:

as shown in fig. 5, the rotating end of the second rotating mechanism 6 is provided with a hollow round pipe 81 inside, specifically, the round pipe 81 is installed on the fixing frame 65, the spray head 7 is provided with a plurality of, the spray head 7 is hinged to the first end of the round pipe 81, the first end of the round pipe 81 is provided with a plurality of hinge lugs, and the spray head 7 is hinged to the corresponding hinge lugs.

Shower nozzle 7 is prior art, and the market is purchased can, and 7 quantity of shower nozzle are set for according to actual demand, if set up three, four, five etc. all can, the articulated shaft of shower nozzle 7 is on a parallel with pipe 81 tangential direction, and all shower nozzles 7 are along pipe 81 circumference evenly distributed.

As shown in fig. 5, a push-pull ring 83 is slidably disposed on the circular tube 81, the push-pull ring 83 is connected to the nozzle 7 through a connecting rod 84, the connecting rod 84 is a straight rod, two ends of the connecting rod 84 are respectively hinged to the push-pull ring 83 and the nozzle 7, and hinge axes at two ends of the connecting rod 84 are both parallel to a tangential direction of the circular tube 81.

As shown in fig. 5, the circular tube 81 is further provided with a push-pull ring driving mechanism 82 capable of driving the push-pull ring 83 to slide along the axial direction of the circular tube 81, and the push-pull ring driving mechanism 82 is controlled by the control unit; the push-pull ring driving mechanism 82 can adopt a push rod motor, an air cylinder and the like, the push-pull ring driving mechanism 82 is installed on the circular tube 81, the axes of the push-pull ring driving mechanism and the circular tube are parallel, the movable end of the push-pull ring driving mechanism 82 is connected to the push-pull ring 83, in the embodiment, the push-pull ring 83 is circular, an outer flange is arranged at the top of the push-pull ring 83, and the movable end of the push-pull ring driving mechanism 82 is specifically connected to the outer flange of the push-pull ring 83.

Further, in order to ensure that the push-pull ring 83 moves smoothly, the two push-pull ring driving mechanisms 82 are symmetrically distributed on two sides of the circular tube 81, and the two push-pull ring driving mechanisms 82 work simultaneously, so that the two sides of the push-pull ring 83 are uniformly stressed and operate smoothly.

Further, the push-pull ring driving mechanism 82 may also adopt a motor-driven lead screw structure, the lead screw is connected with the push-pull ring 83 through a thread, and when the motor drives the lead screw to rotate, the push-pull ring 83 can be driven to slide.

Each spray head 7 is connected to an external fire suppressant source through a pipe passing through the interior of the circular tube 81.

Further, as shown in fig. 5, a guide rail 811 parallel to the circular pipe 81 is disposed on the circular pipe 81, a sliding groove is disposed on the inner side of the push-pull ring 83, the sliding groove and the guide rail 811 are in sliding fit, a plurality of guide rails 811 are disposed, if one, two, three, etc., all the guide rails 811 are uniformly distributed along the circumferential direction of the circular pipe 81, and the guide rails 811 are mounted on the circular pipe 81 through screws.

Further, as shown in fig. 5, a main nozzle 85 is coaxially arranged at a first end of the circular pipe 81, the main nozzle 85 is available in the prior art, and the main nozzle 85 penetrates through the inside of the circular pipe 81 through a pipeline and is connected to a fire extinguishing agent source outside.

During practical application, the fire extinguishing agent source of peripheral hardware passes pipe 81 through the pipeline and inside supplies the fire extinguishing agent to each shower nozzle 7, like water etc., push-and-pull ring actuating mechanism 82 works, can make push-and-pull ring 83 along endwise slip, push-and-pull ring 83 rotates around its articulated shaft through connecting rod 84 push-and-pull shower nozzle 7, can adjust the contained angle between shower nozzle 7 and the pipe 81 axis, like fig. 6 promptly, the state shown in 7, and then realize the regulation of shower nozzle 7 spray regime, so that adjust spray regime size in a flexible way according to the condition of a fire actual conditions, improve fire extinguishing efficiency.

The working principle is as follows:

as shown in fig. 1, when the accurate fire extinguishing system for dealing with transformer oil ignition is actually applied, the accurate fire extinguishing system is integrally installed at the top of a transformer oil tank, a fire detection device can detect the fire of the transformer oil tank and transmit a detection signal to a control unit, when the fire is detected, the fire detection device can transmit the detected fire signal to the control unit, and the control unit can control a first sliding mechanism 2, a second sliding mechanism 3, a first rotating mechanism 4, a lifting mechanism 5 and a second rotating mechanism 6 to work so as to adjust a spray head 7 to a position where a directional fire occurs. Specifically, first slide mechanism 2, the cooperation of second slide mechanism 3 can remove shower nozzle 7 and other relevant spare parts to arbitrary position in the horizontal plane, first rotation mechanism 4 then can adjust the rotation position of shower nozzle 7 and other relevant spare parts, the steerable lift of elevating system 5, the inclination of shower nozzle 7 is then adjustable to second rotation mechanism 6, above each movable part cooperation, can realize adjusting shower nozzle 7 to the direction of directional fire source, and then realize accurate putting out a fire, for prior art, when putting out a fire to transformer oil fire condition, its action is more nimble, rapidly, so efficiency of putting out a fire is higher, the precision is higher. Meanwhile, the fire extinguishing agent is saved, centralized fire extinguishing is realized after the fire extinguishing agent moves to a specified position, the spraying is finished within 10 seconds, the response is fast, the internal temperature is continuously detected after the fire extinguishing is finished, a water spraying system is arranged near the transformer, and the water spraying system realizes water spray cooling within 60 seconds after the flame is detected; in summary, compared with the prior art, the fire extinguishing device has the advantages that the positions of the spray heads are adjusted in all directions, the fire extinguishing efficiency is higher, meanwhile, the fire extinguishing agent is saved, centralized fire extinguishing is realized after the fire extinguishing device is moved to the specified position, the response is fast, open fire is effectively avoided, and the potential safety hazard during use is reduced.
