[0033] The technical scheme of the utility model is further described in detail below by the drawings and embodiments.

[0034] Figure 1 , Figure 2 And Figure 3 A kind of suspension formula fire extinguishing device structure schematic view, front view and use state schematic view are provided for the utility model embodiment respectively, as shown in Figure 1 、 Figure 2 And Figure 3 , including adapter 1, chute 2, moving slider 3, fixing piece 4, first gear 5 and second gear 6 that mutually engage, tank connecting piece 7, tank 8 and nozzle 9, the structure of suspension formula fire extinguishing device is specifically introduced below.

[0035] Adapter 1 is used to realize the installation of device, such asFigure 4 As shown, specifically, the adapter 1 can be a flat plate structure with mounting holes, through which the fire extinguishing device can be installed in the reserved installation position.

[0036] The slide groove 2, fixed on the adapter 1, is used to allow the tank 8 to slide; preferably, as shown in the figure... Figure 5 As shown, the slide 2 is a T-shaped slide 2, which is welded to the adapter 1.

[0037] The movable slider 3 is slidably mounted on the slide groove 2 and can move along the slide groove 2. The top of the movable slider 3 is provided with a movable end that is adapted to the slide groove 2, and the bottom of the movable slider 3 is provided with a connecting end for connecting with the tank body connector 7. Preferably, as follows... Figure 6 As shown, when the slide 2 is a T-shaped slide 2, the moving end of the movable slider 3 is T-shaped, and the T-shaped movable slider 3 fits into the T-shaped slide 2, thereby realizing the flexible sliding of the movable slider 3 on the slide 2. In some preferred embodiments, the suspended fire extinguishing device also includes two baffles, which are respectively fixed at both ends of the slide 2, thereby fixing the movable slider 3 in the slide 2. Specifically, mounting holes can be opened on the sides of the baffles and both ends of the slide 2, and the two can be fixed by screws.

[0038] The tank connector 7 has a connecting end at the top for connecting the tank connector 7 and the movable slider 3, and a fixing end at the bottom for fixing the tank connector 7 and the tank 8.

[0039] The first gear 5 and the second gear 6 are symmetrical and are used to achieve the rotational connection between the tank connector 7 and the movable slider 3. The sides of the first gear 5 and the second gear 6 mesh with each other. The connection end of the first gear 5 to the movable slider 3 is fixed, and the connection end of the second gear 6 to the tank connector 7 is fixed. In a specific example, such as... Figure 7 and Figure 8 As shown, both the first gear 5 and the second gear 6 are flat gears. The gear surfaces of the first gear 5 and the second gear 6 are arranged opposite each other, and the two gears are locked when they are close to mesh.

[0040] The fixing member 4 is used to connect the movable slider 3 and the tank 8. The fixing member 4 passes through the connecting end of the movable slider 3, the first gear 5, and the second gear 6 in sequence, and is connected to the connecting end of the tank connecting member 7. In a preferred embodiment, the fixing member 4 may specifically include a bolt 41 and a nut 42. The bolt 41 passes through the connecting end of the movable slider 3, the first gear 5, the second gear 6, and the tank connecting member 7 in sequence, and is screwed to the nut 42, thereby fixing the tank 8 to the movable slider 3. Further, the connecting end of the movable slider 3 preferably has a first circular hole, the center of the first gear 5 and the second gear 6 preferably has a second circular hole and a third circular hole, respectively, and the connecting end of the tank connecting member 7 preferably has a fourth circular hole. The bolt 41 of the fixing member 4 passes through the first circular hole, the second circular hole, the third circular hole, and the fourth circular hole in sequence, and is screwed to the bolt 41, thereby fixing the components together.

[0041] The top of the tank body 8 is connected to the fixed end at the bottom of the tank body connector 7, and the bottom is provided with a discharge port. Dry powder extinguishing agent is placed inside the tank body 8 for extinguishing fires. It should be noted that those skilled in the art can select the type of extinguishing agent inside the tank body 8.

[0042] Nozzle 9 is connected to the discharge port of tank 8, such as... Figure 9 As shown, the bottom and sides of nozzle 9 are provided with multiple injection holes for the discharge of extinguishing agent. These multiple injection holes allow the discharged extinguishing agent to diffuse in all directions, expanding the extinguishing area. Additionally, they act as a buffer, reducing temperature. Specifically, the extinguishing agent discharge process is electrically activated. The tank 8 contains a gas-generating agent. Upon electric activation, a large amount of gas is generated inside the tank, creating pressure that forces open the sealing membrane at the bottom of the tank 8, allowing the extinguishing agent to be discharged and cover the burning material to extinguish the fire.

[0043] When the fire extinguishing device is in use, with nut 42 not tightened, the first gear 5 and the second gear 6 are disengaged. Regardless of whether the adapter 1 is horizontally installed, the installation angle of the tank body 8 can be adjusted arbitrarily through the tank body connector 7 to make the nozzle 9 vertical. When vertically downward, the agent inside is sprayed out most completely, resulting in the best fire extinguishing effect. If it is tilted and not vertical, more agent will remain inside, and less agent will be sprayed, affecting the fire extinguishing effect. During use, adjust the installation angle of the tank body connector 7 to drive the tank body 8 and the second gear 6 to rotate. Stop adjusting when the nozzle 9 is vertical, and then tighten nut 42. The first gear 5 and the second gear 6 gradually move closer together, and finally the first gear 5 and the second gear 6 are engaged and locked, thereby realizing the adjustment of the angle of the tank body 8. Even when the adapter 1 is not horizontal, the nozzle 9 can still be vertical. Under different reserved installation position angles, this ensures the lowest residual spray rate, the maximum fire extinguishing effect, and maximizes the safe operation of the wind turbine.

[0044] In a preferred embodiment, to ensure the stability of the tank 8 during the adjustment process, the number of the aforementioned slide 2, movable slider 3, fixing member 4, and interlocking first gear 5 and second gear 6 are all two, symmetrically arranged and moving synchronously. Correspondingly, the tank connecting member 7 can be Y-shaped, and the top of the tank connecting member 7 can be provided with two connecting ends. Each connecting end corresponds to a slide 2, a movable slider 3, a fixing member 4, an interlocking first gear 5 and a second gear 6, thereby realizing the rotation adjustment of the tank 8 synchronously through two sets of transmission components.

[0045] The suspended fire extinguishing device provided in this embodiment can effectively control the vertical downward stability of the nozzle of the suspended ultra-fine dry powder fire extinguishing device under different reserved installation position angles, effectively ensuring the normal operation of the wind turbine fire protection system, effectively ensuring the fire extinguishing effect of the wind turbine fire protection system, improving the safety and prevention capabilities of the wind turbine, and protecting the normal operation of the wind turbine.
