[0029] Please refer to Figures 1-4 In the embodiment, a fire extinguishing device includes a water pipe 1, a slide seat 2, a water spraying mechanism 3 and a pushing mechanism 4, wherein:

[0030] A plurality of water pipes 1 are uniformly arranged along the frame of the stereo garage, a plurality of drainage holes 11 are formed in the bottom of the water pipe 1, and the drainage holes 11 are covered with openable and closable sealing covers 12; the slide seat 2 is slidingly connected with the bottom of the water pipe 1, and a water receiving groove 21 is formed in the slide seat 2; the water spraying mechanism 3 includes a water spraying pipe 31, a sprayer 32 rotatably connected to the water outlet end of the water spraying pipe 31 and a vision sensor 33 arranged on the sprayer 32; the water spraying pipe 31 is communicated with the drainage hole 11 through the water receiving groove 21; and the pushing mechanism 4 includes a push rod 41, and the top end of the push rod 41 penetrates through the water receiving groove 21 and abuts against the sealing cover 12.

[0031] The upward movement of the push rod 41 can lift the sealing cover 12, so that the water in the water pipe 1 flows into the water collecting groove 21 through the corresponding drain hole 11, and then is sprayed to the fire point through the spray head 32. The visual sensor 33 is used for accurately positioning the fire point and controlling the spray head to spray water. Specifically, the visual sensor 33 transmits the collected position information of the fire point to the control system, and the control system controls the movement of the slide 2 and the rotation of the spray head 32 according to the information, so that the spray head can accurately aim at the fire source, and ensure that the fire extinguishing water flow accurately covers the fire source.

[0032] Further, the water outlet 22 is provided at the bottom of the water collecting groove 21, and the water spray pipe 31 is connected to the water outlet 22 to guide the water into the spray head 32. It should be particularly pointed out that the push rod 41 is connected to the water collecting groove 21 through another mounting hole, so that the push rod 41 can move axially, and the shaft hole connection needs to be waterproofed.

[0033] Further, the push mechanism 4 further comprises a push plate 42 provided in the water collecting groove 21 and connected to the end of the push rod 41, and a plurality of jacks 43 are provided on the push plate 42, and a cylindrical portion 44 coaxial with the jacks 43 is provided at the bottom of the jacks 43. The push rod 41 drives the horizontal push plate 42 to move upward, so that the jacks 43 lift the corresponding sealing cover 12. In order to ensure that the jacks 43 and the sealing cover 12 do not dislocate, the movement distance of the slide 2 is set as a multiple of the center distance between adjacent sealing covers 12. The movement of the push rod 41 is controlled by the control system, and when the slide 2 reaches the specified position, the control system controls the upward movement of the push rod 41 to lift the sealing cover 12. After the fire is extinguished, the control system controls the output end of the electric push rod 41 to retract, drives the push plate 41 to descend, and the sealing disc 12 is reset.

[0034] Further, the water pipe 1 is provided with parallel slide edge strips 13, and slide grooves 23 are provided on the slides 2 located on both sides of the water collecting groove 21, and the slide edge strips 13 slide in the slide grooves 23.

[0035] Further, a drive wheel 24 is provided in the slide groove 23 and is in sliding connection with the slide edge strip 13. The drive wheel 24 is driven to rotate by the motor 25, and the friction between the drive wheel 24 and the slide edge strip 13 drives the slide 2 to move.

[0036] Further, the water pipe 1 is further provided with an elastic member 14 corresponding to the sealing cover 12, one end of the elastic member 14 abutting against the sealing cover 12 and the other end abutting against the inner wall of the water pipe 1. When the fire extinguishing is not started, the elastic member 14 is in a compressed state, so that the sealing cover 12 is tightly attached to the drain hole 11 to prevent water leakage. When the fire extinguishing is started, the jacks 43 lift the sealing cover 12 upward, and the elastic member 14 is further compressed, so that the water in the water pipe 1 flows downward through the drain hole 11.

[0037] Further, the water spraying pipe 31 is a telescopic pipe. The telescopic pipe can change length flexibly according to the fire extinguishing demand, so that the nozzle 32 is closer to the fire source, and the fire extinguishing effect is improved. After the position information collected by the visual sensor 33 is transmitted to the control system, the control system accurately controls the telescopic length of the telescopic pipe.

[0038] Further, the water spraying pipe 31 and the nozzle 32 are rotationally connected, so that the water spraying direction can be changed flexibly, and the fire extinguishing effect is improved.

[0039] Further, the cross section of the water conveying pipe 1 is rectangular, so that the water conveying pipe 1 is convenient to connect with the sliding seat 2.

[0040] In the operation of the utility model, when the visual sensor 32 detects the fire source, the position information of the fire source is transmitted to the control system, the control system controls the sliding seat 2 to move to the corresponding position, then the electric push rod 41 moves upward, pushes the sealing cover 12 to lift upward, at the same time, the control system controls the water spraying pipe 31 to extend or retract according to the position information of the fire source, so that the nozzle 32 is closer to the fire source. Because the sealing cover 12 is lifted, the water in the water conveying pipe 1 flows downward to the water receiving groove 21, and then flows to the nozzle 32 through the water spraying pipe 31, and sprays the fire source to extinguish the fire. The nozzle 32 can change direction in real time according to the position information of the fire source collected by the visual sensor 32, and aims at the ignition point, so that the fire can be extinguished effectively. When the fire source is extinguished, the control system controls the push rod to move downward, the sealing cover 12 is reset, at the same time, the control system controls the water spraying pipe 31 to retract and reset, and the whole fire extinguishing device returns to the standby state, and waits for the next fire to start working again.

[0041] Although the present specification is described according to the embodiments, not every embodiment contains only one independent technical scheme, and the description mode of the specification is only for the sake of clarity, and the person skilled in the art should consider the specification as a whole, and the technical scheme in each embodiment can be combined appropriately to form other embodiments that can be understood by the person skilled in the art.

[0042] Therefore, the above description is only the preferred embodiment of the present application, and is not used to limit the implementation scope of the present application. That is, various equivalent transformations made according to the scope of the claims of the present application are all within the protection scope of the claims of the present application.
