At the same time, the nozzle 13 can rotate at the lower part of the dry powder tank 19. The bottom plate 1 is connected to a driving component that can drive the second movable part 17 to move, and the top plate 14 is connected to a power component that can provide power for the movement of the first movable part 12. A monitoring component that can monitor the fire situation is provided on the bottom plate 1, and the first movable part 12 is connected to a rotating component that can drive the nozzle 13 to rotate.

[0036] See also Figure 2 , and also includes two support frames 110, which are symmetrically fixed on the upper side of the first moving member 12, and the dry powder tank 19 and the support frames 110 are both snap-fitted.

[0037] See also Figure 2-Figure 3The driving assembly includes a first motor 15, which is fixed on the upper left side of the base plate 1. A first screw rod 16 is fixed on the output shaft of the first motor 15. The first screw rod 16 is rotatably connected to the top plate 14, and the first screw rod 16 is threadedly connected to the second moving member 17.

[0038] See also Figure 3 The power assembly includes a second motor 112, which is fixed to the lower rear side of the top plate 14. The output shaft of the second motor 112 is fixed with a second screw rod 113, which is rotatably connected to the bottom plate 1 and is threadedly connected to the first moving member 12.

[0039] See also Figure 4-Figure 5 The rotating assembly includes a first gear 114, a shaft is provided on the upper part of the first gear 114, the first gear 114 is rotatably connected to the middle of the lower part of the first movable member 12 through the shaft, the shaft 114 on the first gear is fixedly connected to the nozzle 13, and a third motor 117 is fixedly connected to the lower side of the first movable member 12. A second gear 118 is fixed on the output shaft of the third motor 117, and the second gear 118 and the first gear 114 are engaged with each other.

[0040] See also Figure 4 The monitoring component includes a smoke sensor 115, which is fixed to the rear portion of the lower side of the base plate 1. The smoke sensor 115 is electrically connected to the first motor 15 through a control module. A fire detector 116 is fixed to the front portion of the lower side of the base plate 1. The fire detector 116 is electrically connected to the first motor 15 through a control module. The fire detector 116 is electrically connected to the third motor 117 through a control module.

[0041] When people need to install a fire extinguishing device, this device can be used. Because when a fire occurs, smoke floats upward, people install this device on the ceiling. When a fire occurs, the smoke sensor 115 and the fire detector 116 will both detect it. The smoke sensor 115 and the fire detector 116 are both electrically connected to the first motor 15 through the control module, so that the smoke sensor 115 and the fire detector 116 both control the first motor 15 to start, and the first motor 15 drives the first screw rod 16 to rotate clockwise. The first screw rod 16 is threadedly connected to the second moving member 17, so that the second moving member 17 moves downward, and the second moving member 17 drives the dry powder tank 19 to move downward, so that the piston at the lower part of the dry powder tank 19 is squeezed and opened. Open, then the smoke sensor 115 and the fire detector 116 both control the first motor 15 to turn off, and at the same time the fire detector 116 controls the third motor 117 to start, the third motor 117 drives the second gear 118 and then drives the first gear 114 to rotate, and the shaft on the first gear 114 drives the sprinkler head 13 to rotate, so that the sprinkler head 13 can be aimed at the fire, and then the fire detector 116 controls the third motor 117 to turn off, and then because the piston at the bottom of the dry powder tank 19 is opened, the high pressure inside the dry powder tank 19 squeezes the dry powder, causing the dry powder to be sprayed out through the sprinkler head 13 until the flame is completely extinguished, when the fire is over, the smoke sensor 115 and the fire detector 116 both control the first motor 15 to start again, and the first motor 15 drives the first The rod 16 rotates counterclockwise, causing the second movable member 17 to move upward and reset. The second movable member 17 drives the dry powder tank 19 to move upward, so that the piston at the lower part of the dry powder tank 19 no longer squeezes the nozzle 13, and the piston at the lower part of the dry powder tank 19 is closed because it is no longer squeezed. Because the dry powder tank 19 will spray out the dry powder inside during use, resulting in a drop in pressure inside the dry powder tank 19 or the depletion of dry powder, making it unable to work normally again, the dry powder tank 19 needs to be replaced after each use. When the dry powder tank 19 is to be replaced, people control the second motor 112 to start, and the second motor 112 drives the second screw rod 113 to rotate clockwise. The second screw rod 113 is threadedly connected to the first movable member 12, causing the first movable member 12 to move downward, and the second screw rod 113 is threadedly connected to the first movable member 12. A moving part 12 drives the support frame 110 to move downward, the first moving part 12 drives the first gear 114 and then drives the nozzle 13 to move downward, the nozzle 13 drives the dry powder tank 19 to move downward, and the dry powder tank 19 is separated from the second moving part 17. When the upper part of the first moving part 12 moves downward to contact and squeeze the bottom plate 1, people turn off the second motor 112, and then people can replace the dry powder tank 19. People remove the old dry powder tank 19 and then reinstall the new dry powder tank 19. After the replacement is completed, people start the second motor 112 again, and the second motor 112 drives the second screw rod 113 to rotate counterclockwise, so that the first moving part 12 moves upward and resets. The first moving part 12 drives the support frame 110 to move upward.The first movable member 12 drives the first gear 114 and then drives the upward spray head 13 to move downward, and the spray head 13 drives the dry powder tank 19 to move upward, and the dry powder tank 19 is re-engaged with the second movable member 17. The support frame 110 can stabilize the dry powder tank 19 during the up and down movement of the dry powder tank 19. When the first movable member 12 moves upward and resets, people turn off the second motor 112, and the replaced dry powder tank 19 will be refilled with dry powder and pressure for the next use. At the same time, people also need to regularly inspect the dry powder tank 19. When the dry powder tank 19 is damaged, the dry powder tank 19 needs to be replaced and no longer used. The above operation adopts the method of replacing the dry powder tank 19 each time instead of people using an additional device to replenish dry powder each time. At the same time, the detachable dry powder tank 19 can facilitate people to inspect the dry powder tank 19. When the dry powder tank 19 is damaged, it is only necessary to replace the dry powder tank 19 without replacing the entire device, which is more convenient and saves time and effort.

[0042] Example 2: Based on Example 1, please refer to Figure 6-Figure 8 , and also includes a clamping mechanism that can clamp the dry powder canister 19 to prevent the dry powder canister 19 from tipping over when it is lowered. The clamping mechanism includes three extrusion members 21, which are slidably connected to the corresponding fixed rods 11, and the extrusion members 21 are all extruded and matched with the bottom plate 1. Sliding blocks 22 are slidably connected to the extrusion members 21, and the sliding blocks 22 are extruded and matched with the corresponding fixed rods 11. Arc blocks are provided on the side where the extrusion members 21 are close to each other, and the arc blocks are extruded and matched with the dry powder canister 19. A third spring 23 is fixed between the arc blocks and the corresponding sliding blocks 22.

[0043] See also Figure 6-Figure 8 , also includes a connecting frame 2, the connecting frame 2 is fixed to the lower side of the first moving member 12, and three guide rails are circumferentially arranged on the upper part of the connecting frame 2. The guide rails are composed of vertical guide rails and inclined guide rails, and the guide rails are slidably connected to the corresponding extrusion members 21.

[0044] When people replace the dry powder canister 19, the dry powder canister 19 will move downward. After the dry powder canister 19 is separated from the second moving member 17, the dry powder canister 19 may fall over due to the lack of component restrictions. Therefore, a clamping mechanism that can clamp the dry powder canister 19 is provided. The following is its working principle: when people replace the dry powder canister 19, the first moving member 12 drives the first gear 114 and then drives the nozzle 13 to move downward. The nozzle 13 drives the dry powder canister 19 to move downward. At the same time, the first moving member 12 drives the connecting frame 2 and then drives the extruding member 21 to move downward. Under the clamping action of the extruding member 21 on the dry powder canister 19, the dry powder canister 19 can be prevented from falling over during the downward process after being separated from the second moving member 17. When the extruding members 21 all move to the bottom of the fixed rod 11, the connecting frame 2 continues to move downward, so that the inclined guide rails on the connecting frame 2 all squeeze the corresponding extruding members 21, and the extruding members 21 are all squeezed away from each other. When one side moves, the sliding blocks 22 are blocked by the fixed rod 11, so that the third springs 23 are compressed and the extruding members 21 release the clamping of the dry powder canister 19, thereby facilitating people to replace the dry powder canister 19. When people have finished replacing, the first moving member 12 drives the first gear 114 and then drives the spray head 13 to move upward, and the spray head 13 drives the dry powder canister 19 to move upward. At the same time, the first moving member 12 drives the connecting frame 2 to move upward, so that the connecting frame 2 no longer squeezes the extruding members 21, and the third springs 23 are reset. The third springs 23 drive the extruding members 21 to move in the direction of approaching each other and reset, so that the extruding members 21 clamp the dry powder canister 19 again, and the upward movement of the connecting frame 2 drives the extruding members 21 to move upward and reset. The above operation is carried out by setting the extruding member 21, so that the extruding member 21 can clamp the dry powder canister 19 during the downward movement of the dry powder canister 19, thereby preventing the dry powder canister 19 from tipping over due to lack of restriction during the downward movement.

[0045] See also Figure 9-10 , and also includes a transport mechanism that can transport the new dry powder canister 19 upward during the process of replacing the dry powder canister 19, eliminating the need for manual transport by people. The transport mechanism includes a fourth motor 3, which is fixed to the upper right part of the base plate 1. A rope roller 31 is fixed to the output shaft of the fourth motor 3, and one end of a pull rope 32 is fixed to the rope roller 31. The pull rope 32 is wound around the rope roller 31, and a hook 33 is fixed to the other end of the pull rope 32. The hook 33 is engaged with the handle on the dry powder canister 19.

[0046] Because this device is installed on the ceiling, people need to move the dry powder canister 19 up to replace it every time the dry powder canister 19 is replaced, and the dry powder canister 19 itself is relatively heavy, which is troublesome to carry. Therefore, a carrying mechanism is provided to replace people's manual carrying of the dry powder canister 19. The following is its working principle: when the dry powder canister 19 needs to be replaced, the first moving member 12 drives the first gear 114 and then drives the spray head 13 to move downward, and the spray head 13 drives the dry powder canister 19 to move downward. People take down the old dry powder canister 19 and hang it on the hook 33, and then people start the fourth motor 3 to rotate forward. The output shaft of the fourth motor 3 rotates and drives the rope roller 31 to rotate forward, so that the pull rope 32 is no longer wound around the rope roller 31. Because of the weight of the dry powder canister 19 itself, the dry powder canister 19 drives the hook 33 to move downward, and the hook 33 drives the pull rope 32 to move downward, so that the pull rope 32 stretches downward. When it reaches the bottom, people turn off the fourth motor 3 and remove the old dry powder canister 19 from After the hook 33 has moved to the top, people can remove the new dry powder can 19 from the hook 33 and reinstall it on the spray head 13. Finally, people control the first moving member 12 to drive the first gear 114 to drive the spray head 13 to move upward, and the spray head 13 drives the new dry powder can 19 to move upward and reset. The above operation is driven by the fourth motor 3 to drive the rope roller 31 to rotate, and the rope roller 31 drives the pull rope 32 to retract and release, so that the hook 33 can move up and down, and people hang the dry powder can 19 on the hook 33, so that the dry powder can 19 can be carried up and down, which makes it convenient for people to replace the dry powder can 19. People no longer need to carry the dry powder can 19, which saves time and effort.

[0047] See also Figure 11-13 , and also includes a shock-absorbing mechanism that can prevent the dry powder canister 19 from being separated from the shaft on the first gear 114 due to shaking when the dry powder canister 19 is replaced. The shock-absorbing mechanism includes four third guide rods 4, and the third guide rods 4 are circumferentially slidingly connected to the lower part of the first movable member 12. A fixing member 42 is fixed between the side of the third guide rod 4 away from the first movable member 12, and the fixing member 42 is engaged with the dry powder canister 19. A fourth spring 41 is fixed between the fixing member 42 and the first movable member 12.

[0048] Because the dry powder canister 19 filled with dry powder is usually very heavy, when installing a new dry powder canister 19 on the nozzle 13, the hand may slip, causing the dry powder canister 19 to fall down relatively heavily, and then causing the lower part of the dry powder canister 19 to deform, etc. Therefore, a shock-absorbing mechanism is provided to reduce the shock of the dry powder canister 19 to prevent the dry powder canister 19 from being damaged. The following is its working principle; when people remove the old dry powder canister 19, the old dry powder canister 19 no longer squeezes the fixing part 42, and the fourth spring 41 is reset from the compressed state, and the fourth spring 41 drives the fixing part 42 to move upward and reset, and the fixing part 4 2 drives the third guide rods 4 to move upward. Then, when installing a new dry powder canister 19, people drive the dry powder canister 19 to move toward the side close to the nozzle 13, so that the lower part of the dry powder canister 19 cooperates with the nozzle 13. During this process, the dry powder canister 19 will press the fixing member 42 downward. The fixing member 42 drives the third guide rods 4 to move downward, and the fourth spring 41 is compressed again. The above operation is achieved by providing the fourth spring 41 and the fixing member 42. Under the buffering action of the fourth spring 41, the fixing member 42 can play a certain supporting role for the dry powder canister 19, thereby providing buffering protection for the lower part of the dry powder canister 19 when people install the dry powder canister 19.
