[0004] However, during actual use, it was found that although the device can swing up and down repeatedly when multiple nozzles rotate, thereby further expanding the fire extinguishing range, the installation height of the fire extinguishing device varies due to the different floor heights of the building. If the height of the fire extinguishing device is too high, it will affect the actual fire extinguishing effect. Therefore, this application provides a linkage-controlled heptafluoropropane gas fire extinguishing device to meet the requirements. Utility Model Content

Furthermore, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0028] like Figure 1 , Figure 3 and Figure 4As shown, an embodiment of this utility model provides a linkage-controlled heptafluoropropane gas fire extinguishing device, comprising: a storage tank 1, with a lifting assembly 2 and a swirl spray assembly 3 respectively disposed on the outer wall of the storage tank 1; the lifting assembly 2 includes a top plate 201 installed on the top of the storage tank 1, a motor 202 providing driving force fixedly mounted at the bottom of the top plate 201, a drive wheel 203 fixedly mounted at the top of the output shaft of the motor 202, and a driven wheel 204 rotatably connected to the top of the top plate 201, the outer wall of the drive wheel 203 meshing with the driven wheel 204, and the driven wheel... A gear 205 meshes with the outer wall of the driven wheel 204. The bottom of the gear 205 is rotatably connected to the top plate 201. A screw 206 is threadedly connected to the inner wall of the gear 205. The screw 206 passes through the top plate 201, and a base plate 207 is fixedly mounted on the bottom of the screw 206. There are four sets of gears 205 and screws 206, and the four sets of gears 205 and screws 206 are evenly distributed on the periphery of the driven wheel 204. By using gears 205 and screws 206, the stability of the storage tank 1 and the base plate 207 during movement is improved, ensuring the normal use of the device.

[0029] like Figure 2 and Figure 5 As shown, the rotary spray assembly 3 includes a second motor 301 installed on the outer wall of the storage tank 1. A second drive wheel 302 is fixedly mounted at the end of the water pump of the second motor 301. A connecting pipe 303 is rotatably connected to the bottom of the storage tank 1. A second driven wheel 304 is fixedly mounted on the outer wall of the connecting pipe 303. A transmission belt 305 is engaged with the outer wall of the second drive wheel 302. The side of the transmission belt 305 away from the second drive wheel 302 is engaged with the second driven wheel 304. A connecting disc 306 is fixedly connected to the bottom of the connecting pipe 303. A nozzle 307 is fixedly connected to the outer wall of the connecting disc 306. The second motor 301 drives the second drive wheel 302 to rotate. The rotation of the second drive wheel 302 drives the transmission belt 305 to rotate. The rotation of the transmission belt 305 drives the second driven wheel 304 and the connecting pipe 303 to rotate. The rotation of the connecting pipe 303 drives the connecting disc 306 and the nozzle 307 to rotate, thereby realizing rotary fire extinguishing, improving fire extinguishing efficiency, and ensuring the practicality and reliability of the device.

[0030] like Figure 2 and Figure 3 As shown, a fixing plate 208 is fixedly mounted on the top of the top plate 201. The top of the fixing plate 208 has a fixing hole 209.

[0033] The technical solution provided by this utility model, during operation, drives the active wheel 203 to rotate via motor 202, which in turn drives the driven wheel 204 to rotate, which in turn drives the four sets of gears 205 to rotate. The gears 205 rotate on the outer wall of the screw 206, causing the screw 206 to move longitudinally. The longitudinal movement of the screw 206 causes the base plate 207 to move longitudinally, ultimately causing the storage tank 1 and the spray assembly 3 to change in height. This facilitates the adjustment of the device's height according to different building interior heights.

[0034] The motor 301 drives the drive wheel 302 to rotate, which in turn drives the transmission belt 305 to rotate. The transmission belt 305 then drives the driven wheel 304 and the connecting pipe 303 to rotate. The rotation of the connecting pipe 303 then drives the connecting disc 306 and the nozzle 307 to rotate, thereby achieving rotating fire extinguishing, improving fire extinguishing efficiency, and ensuring the practicality and reliability of the device.

[0035] The above description is only a preferred embodiment of the present utility model.
