[0028] Example 2

[0029] like Figure 1-7As shown, a block-type intelligent fire monitoring, early warning and active fire extinguishing system includes a fire agent storage tank 1, a sprayer 2, a fire monitoring system and an intelligent fire control platform. The fire agent storage tank 1 and the sprayer 2 are connected by a water supply pipe 3, and an intelligent control valve 4 and a driving device are installed on the water supply pipe 3. The fire monitoring system includes a plurality of sensor detectors 49. The fire agent water storage tank 8 includes a water storage tank 8 and an agent tank 9.

When a fire occurs, the power supply device 16 energizes the electromagnet 14. The electromagnet 14 generates a magnetic field to drive the magnetic part 13 to move toward the electromagnet 14, so that the first sliding sealing plate 12 slides toward the inside of the first slide slot 11, opens the liquid outlet 10, and mixes the fire-fighting agent with the water in the water storage tank 8. The liquid sprayer 2 includes a water spray pipe body 17, a horizontal mounting plate 18 and a splash plate 19. The inside of the water spray pipe body 17 is provided with a water spray channel 20. The outer sleeve of the water spray pipe body 17 is provided with a sleeve 21, and an active chamber 22 is provided inside the sleeve 21. A return spring 23 is provided inside the active chamber 22. The top of the return spring 23 is connected to the top of the sleeve 21, and the bottom of the return spring 23 is connected to a stretching rod 24, and the bottom of the stretching rod 24 is connected to a splash plate 19. A valve pipe 25 is transversely arranged at the bottom of the water spray pipe body 17. A sliding channel 26 communicating with the water spray channel 20 is provided in the valve pipe 25. A slider 27 and a glass ball 28 are installed in the sliding channel 26. A chamfered surface 29 is provided on one side of the slider 27 close to the water spray channel 20. The other end of the slider 27 is against the glass ball 28. The interior of the glass ball 28 is filled with liquid.

The two sides of the valve pipe 25 are connected with horizontal mounting plates 18, and mounting bolts 48 are arranged on the horizontal mounting plates 18. The horizontal mounting plates 18 are used to connect with the top of the roof. After a fire occurs, the high temperature will cause the glass ball 28 to burst. After the water supply pipe 3 supplies water, the water flow in the water spray pipe flows downward. The two sliders 27 move in opposite directions under the action of the chamfered surfaces 29 and the water flow, so that the water flows out from the bottom of the water spray pipe body 17, impacting the splash plate 19 to become water splashes for fire extinguishing. A support rod 30 is also installed in the water spray pipe body 17. A transmission shaft 31 is rotatably installed in the middle of the inner cavity of the support rod 30. The top of the transmission shaft 31 passes through the support rod 30 and extends upward.A blade 32 is installed on the top of the transmission shaft 31, and the blade 32 is located in the water spray channel 20. A first bevel gear 33 is also installed at the bottom of the transmission shaft 31. A small generator 34 is also provided on the outside of the water spray pipe body 17. A driven shaft 35 is installed on the output end of the small generator 34. A second bevel gear 36 is installed on the front end of the driven shaft 35. The driven shaft 35 penetrates the water spray pipe body 17 and penetrates into the inner cavity of the support rod 30. The second bevel gear 36 is meshed with the first bevel gear 33. The small generator 34 is connected to the power supply device 16 through a wire. When water flows through the water spray pipe, it drives the blade 32 to rotate. The blade 3 2 drives the transmission shaft 31 to rotate, and the transmission shaft 31 drives the driven shaft on the small generator 34 to rotate, thereby driving the small generator 34 to generate electricity. After the power supply device 16 is charged, it supplies power to the electromagnet 14, thereby opening the liquid outlet 10 to allow the fire-fighting agent and water to mix. The sprinkler 2 is generally provided with multiple, and correspondingly, multiple small generators 34 are also provided. The advantage of this embodiment is that it can ensure that the fire-fighting agent and water can be automatically mixed during fire extinguishing, without the need for manual addition during fire extinguishing, thereby improving the mixing speed. At the same time, if the fire-fighting agent is mixed with water in advance, it will also cause the mixing time to be too long, and the fire-fighting agent will become ineffective.

[0030] Example 3

[0031] This embodiment is partly the same as the embodiment 2, and the difference is that a water ingress prevention device is further provided on the medicine tank 9, and the water ingress prevention device includes a floating ball 39, a floating rod 40 is installed on the floating ball 39, and a first gear rack 41 is provided on the floating rod 40, and a floating groove 42 is provided on the side wall of the medicine tank 9, and a first gear 43 is rotatably provided on the right side of the floating groove 42, and a second gear 44 is meshed with the right lower side of the first gear 43, and a second slide groove 45 is provided below the second gear 44, and a second sliding sealing plate 46 is slidably provided in the second slide groove 45, and a second gear rack 47 meshed with the second gear 44 is provided above the anti-water ingress sealing plate, and a second gear rack 47 meshed with the second gear 44 is provided above the second sliding sealing plate 46, and the left side of the first gear 43 is provided with a second gear rack 47 meshed with the second gear 44. The first gear 43 drives the second gear 44 to rotate counterclockwise, and the second gear 44 drives the second gear 47 to move rightward, so that the second sliding sealing plate 46 blocks the liquid outlet 10. When the water level in the water tank 8 becomes low, the liquid outlet 10 will be opened by the same principle. The purpose of setting the anti-water inflow device is to prevent the water level from being too high, thereby directly submerging the medicine tank 9. After the fire-fighting agent in the medicine tank 9 is completely mixed with water, it will cause a waste of fire-fighting agent.
