[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 - Figure 3This utility model provides an embodiment of a fire suppression nozzle for electric vehicle sheds, comprising a mounting base 2 for mounting other components. The top of the mounting base 2 is fixedly connected to a connector 1 for mounting the device on a water pipe. The bottom of the mounting base 2 is fixedly connected to a connecting rod 3 for fixing a connecting seat 5. A water pipe plug 7 for blocking water flow is inserted into the lower surface of the mounting base 2. A glass column 4 is mounted at the bottom of the water pipe plug 7. The glass column 4 is an existing structure and can be implemented by those skilled in the art; therefore, it will not be described in detail in this case. The bottom of the connecting rod 3 is fixedly connected to a connector for mounting other components. The connecting seat 5 has a water collecting baffle 13 slidably connected to its inner wall for concentrating water flow into the water channel 9 inside the connecting seat 5. A water dissolving pad 14 is fixedly connected to the lower surface of the water collecting baffle 13 for lifting the water collecting baffle 13. A rotating block 8 is rotatably connected to the lower surface of the connecting seat 5 for driving the water baffle 6 to rotate. A water channel 9 for adjusting the shape of the water spray is opened on the upper surface of the rotating block 8. A water baffle 6 for spreading the water spray range is fixedly connected to the outer wall of the rotating block 8. An arc-shaped piece 10 for facilitating the rotation of the water baffle 6 by the water flow is fixedly connected to the upper surface of the water baffle 6.

[0032] Reference Figure 2 , Figure 3 , Figure 4 The water collecting baffle 13 is designed in an arc shape to facilitate sliding adjustment on the inner wall of the connecting seat 5. The top of the water collecting baffle 13 is fixedly connected to an inclined block 12 for guiding part of the water flow to the edge of the baffle plate 6. The upper surface of the inclined block 12 is provided with an inclined surface, and the inclined block 12 completes the guidance by pulling through the inclined surface. The connecting seat 5 is designed in the shape of a hollow round tube, allowing the water to flow through the connecting seat 5 and out of the water channel 9. The inner wall of the connecting seat 5 is fixedly connected to a support plate 15 for supporting the glass column 4. The support plate 15 is fixedly connected to the bottom of the glass column 4, so that the glass column 4 stably abuts against the water pipe plug 7.

[0033] Reference Figure 3 , Figure 4 The upper surface of the baffle plate 6 is provided with a water-dispersing groove 11 for dispersing the water flow. The water-dispersing groove 11 is arranged in a rotating array around the center line of the baffle plate 6 to improve the dispersion effect. The arc-shaped plate 10 is designed in an arc shape so that the water flow can push the baffle plate 6 to rotate when it flows through it. The arc-shaped plate 10 is arranged in a rotating array around the center line of the baffle plate 6 to improve the use effect of the arc-shaped plate 10. The water-dissolving pad 14 is installed on the inner wall of the connecting seat 5. When the water-dissolving pad 14 dissolves in the water and disappears, the water collecting baffle plate 13 will lose its support and slide down. The water-dissolving pad 14 is made of water-soluble material and will dissolve and disappear in water. The water channel 9 is designed in a rectangular shape so that the sprayed water flow splashes downward in a sheet shape.

[0034] Working principle: During use, the operator installs the device on the water pipe through connector 1. When a fire occurs inside the electric vehicle shed, the device near the fire source will shatter due to the heat of the flames, causing the glass column 4 to break. The water pipe plug 7, which is pushed up by the glass column 4, will fall off, and water will spray out from the bottom of the mounting base 2. The sprayed water will flow in a column shape to the water collecting baffle 13. The water collecting baffle 13 will concentrate most of the water flow into the inside of the connecting base 5. The impact force of the water flow will cause it to spray out through the water channel 9. Since the water channel 9 is rectangular, the sprayed water will splash in a long strip shape towards the bottom of the device. At the same time, the remaining water flow will flow to the water baffle 6 and flow outward from the surface of the water baffle 6. When the water flows through, it will contact the edge of the arc-shaped plate 10, pushing the water baffle 6 to rotate and scatter the water. During this process, the water-dissolving pad 14 inside the connecting base 5 will slowly melt, and the water collecting baffle 13 will slide downward. The inclined baffle 12 will then guide more water flow to the water baffle 6, increasing the radiation range of the water column and preventing the fire from spreading.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
