[0030] A matching cover 223 is provided below the circular cover 215, and a ring-shaped platform 221 is installed on the top of the matching cover 223. An annular protrusion 222 is installed on the top of the matching cover 223, and there are four annular protrusions 222. The four annular protrusions 222 have the same size and are evenly distributed in a ring shape on the periphery of the ring-shaped platform 221. Four cylindrical platforms 213 are installed on the inner side of the matching cover 223.

[0031] By adopting the above technical solution, when the driving device is needed, the micro motor 217 is driven. When the micro motor 217 is driven, it is fixedly installed between the anti-skid roller 214 at the output end, so that the anti-skid roller 214 can be driven to rotate. During the rotation of the anti-skid roller 214, not only can other devices be changed to adjust the angle, but also the slide 216 can be driven to realize circular movement inside the T-shaped slide groove 218, so that the adjustment in four directions can be realized through the movement of the slide 216. When the device is in the process of adjusting the angle, it is installed on the top of the inner side of the circular cover 215 through the annular table 1 211, and then rolled between the ball head telescopic rod 1 212 and the upper external annular table 1 211, and then the cylindrical table 2 213 is rolled on the bottom of the ball head telescopic rod 1 212. In this way, there will be no jamming when the angle of the device is adjusted, and the stability of the device docking can be guaranteed, thereby ensuring the smoothness of the device operation.

[0032] Specifically, an annular platform 211 is installed on the inner side of the top of the circular cover 215, and there are four annular platforms 211. The annular platforms 211 are evenly distributed in a circular ring form on the inner top of the circular cover 215. A ball head telescopic rod 212 is rollingly installed inside the annular platform 211. A cylindrical platform 213 is rollingly installed at one end of the ball head telescopic rod 212 away from the annular platform 211, and there are four cylindrical platforms 213. Spherical grooves of the same size are opened at the bottom of the annular platform 211 and the top of the cylindrical platform 213, and the diameter of the spherical groove is the same as the diameter of the two ends of the ball head telescopic rod 212.

[0033] By adopting the above technical solution, four annular platforms 211, ball head telescopic rods 212, and cylindrical platforms 213 are designed respectively, and are evenly distributed in circular shapes inside the circular cover 215, which can effectively ensure that the device is evenly stressed during the support process.

[0034] Specifically, a spring 224 is installed at the top of the inner side of the matching cover 223 , and two springs 224 are provided. The springs 224 are evenly distributed at the outer peripheral position above the inner side of the matching cover 223 .

[0035] By adopting the above technical solution, two springs 224 are fixedly installed on the inner top of the cover 223, and the springs 224 are evenly distributed in a ring shape on the inner top of the circular cover 215, so that the device can be ensured not to shake during the installation.

[0036] Specifically, a card slot 225 is opened on the inner wall of the matching cover 223 , and the inside of the card slot 225 is in a T-shape. There are two card slots 225 , which are evenly distributed on the inner wall of the matching cover 223 .

[0037] By adopting the above technical solution, by cooperating with the T-shaped slot 225 provided on the inner wall of the cover 223, time can be saved during installation and disassembly, thus improving installation efficiency.

[0038] Specifically, a water storage tray 33 is provided at the bottom of the mating cover 223, and a spray plate 31 is installed at the bottom of the water storage tray 33, and the water storage tray 33 and the spray plate 31 are matched by adhesion. A plurality of groups of spray holes of the same size are opened through the bottom of the spray plate 31, and are evenly distributed in a ring form at the bottom of the spray plate 31, and the water storage tray 33 is slidably installed inside the slot 225.

[0039] By adopting the above technical solution, when the water source enters the water storage pan 33, the spray plate 31 is adhered to the bottom of the water storage pan 33, and the spray hole is opened through the inside of the spray plate 31, so that the water pressure inside the water storage pan 33 will increase, and it will be sprayed out in the form of a shower through the spray plate 31 to achieve uniform fire extinguishing.

[0040] Specifically, a foldable hose 32 is installed on the top of the water storage pan 33 . The foldable hose 32 is made of PVC plastic material, and one end of the foldable hose 32 away from the water storage pan 33 is in communication with the fixed cylinder 1 .

[0041] By adopting the above technical solution, the folding hose 32 is made of PVC material, and the folding hose 32 is designed to be foldable, which can ensure that the folding hose 32 can achieve the function of extension and shortening when being pulled, so that the folding hose 32 will not be broken during use.

The fusible metal sheet 34 is adhesively connected to the matching cover 223 except the contact position of the spray plate 31.

[0043] By adopting the above technical solution, by sticking the fusible metal sheet 34 at the bottom of the card slot 225, the fusible metal sheet 34 can effectively cover and isolate the spray plate 31. When the indoor temperature exceeds 47 degrees, the fusible metal sheet 34 will melt and the spray plate 31 will contact the outside world. This can ensure the stability of the working state of the device, and the probability of electronic damage is small.

[0044] Specifically, the fusible metal sheet 34 is made of a high-temperature material and a low-temperature material in a certain proportion and is made in a mixed form.

[0045] By adopting the above technical solution, according to the characteristics of the fusible metal sheet 34, it can be melted at a specified temperature, so that the sealing and opening effect of the device can be achieved, thereby effectively ensuring the stability of the operation of the device.

[0046] Working principle: When the micro motor 217 is in the driving process, it is fixedly installed between the output end anti-skid roller 214, so that it drives the anti-skid roller 214 to rotate, so that when the anti-skid roller 214 rotates, it rolls between the top of the annular protrusion 222, so that the anti-skid roller 214 presses the edge position of the boss of the matching cover 223, so that the rotation movement trajectory of the matching cover 223 is changed, so that the anti-skid roller 214 can drive the annular platform 211 to adjust the angle through the height of the path during the rolling process, so that the device can adjust the angle at the same time during operation, so that the spraying range of the device is wider, so that in the event of a fire, it can ensure that there will be no dead angle when extinguishing the fire, so as to achieve timely extinguishing of the fire and reduce safety hazards. When the device is in operation, it is rolled and installed between the annular platform 211 and the ball head telescopic rod 212, and the ball head telescopic rod 212 can be adjusted in length, so that the device will not be stuck when adjusting the angle, and can smoothly perform steering adjustment.
