As shown in fig. 1-3, the utility model provides a technical solution: the utility model provides a fire control high temperature smoke exhaust fan, includes air exhaust mechanism 1, and air exhaust mechanism 1 is including the outer wall 114 that bleeds, and the fixed delivery pipe 102 of the outer wall 114 top fixedly connected with that bleeds, fixed delivery pipe 102 outside fixedly connected with electronic water supply valve 101, and in this embodiment, fixed delivery pipe 102 top communicates to the outer wall 114 outside that bleeds, and is connected with external water supply system, as long as open electronic water supply valve 101 just can obtain stable rivers. The bottom end of the fixed water supply pipe 102 is fixedly connected with a fixed connection ring 103, the bottom end of the fixed connection ring 103 is movably connected with a rotary connection ring 113, in the embodiment, a plurality of steel balls with the same size are uniformly arranged between the fixed connection ring 103 and the rotary connection ring 113, and when the rotary connection ring 113 and the fixed connection ring 103 rotate relatively, the steel balls can rotate simultaneously to reduce the friction force between the two rings, so that the rotation between the two rings is smoother and is not easy to wear. Meanwhile, the fixed water supply pipe 102 should be extended to a certain distance below the fixed connection ring 103, so that a follower gasket can be arranged inside the rotary connection ring 113 to seal the joint between the two water supply pipes, thereby preventing water leakage. The bottom end of the rotary connection ring 113 is fixedly connected with the rotary water supply pipe 104, and the bottom end of the rotary water supply pipe 104 is fixedly connected with the sprinkler head 106, in this embodiment, the bottom end of the sprinkler head 106 is a cambered surface, and is provided with inclined sprinkler holes, so that when water flows into the sprinkler head 106, the water can be scattered and sprayed out of the inclined sprinkler holes. As the sprinkler head 106 rotates with the rotating water supply pipe 104, the radius of the water spray also increases, thereby covering a larger area. An annular atomizing nozzle 110 is fixedly connected to the outer side of the rotary water supply pipe 104. When the rotating water supply pipe 104 rotates and the annular atomizing nozzle 110 is opened, a part of water is squeezed into the annular atomizing nozzle 110 and is atomized and sprayed out, thereby achieving the effect of reducing the temperature.

The outer side of the water spraying nozzle 106 is fixedly connected with an air exhaust fan blade 108, the outer side of the air exhaust fan blade 108 is movably connected with a fixed bottom plate 109, the bottom side of the fixed bottom plate 109 is fixedly connected with a ceiling, the whole smoke exhaust fan is hidden above the ceiling of a building, and the space is saved. A temperature sensor 105 is fixedly connected to the bottom end of the fixed base plate 109, a dust sensor 107 is fixedly connected to the bottom end of the fixed base plate 109, the temperature sensor 105 and the dust sensor 107 are electrically connected to the electronic water supply valve 101, and the temperature sensor 105 and the dust sensor 107 are also electrically connected to the rotating motor 112. When the temperature sensor 105 detects an abnormality, which indicates that a fire may occur in the current building, the rotating motor 112 starts to rotate at an accelerated speed and drives the air extracting fan blades 108 to rotate, so as to perform ventilation operation on the fire scene environment and reduce smoke in the air as much as possible. When the dust sensor 107 detects the abnormality, it indicates that the fire in the building has spread to the vicinity of the exhaust fan, and at this time, the rotation speed of the rotary motor 112 is further increased, and the electronic water supply valve 101 is opened to spray to the lower fire scene, so as to reduce the high-temperature suspended substances in the air as much as possible and suppress the fire, thereby creating conditions for the successful evacuation of people. The top end of the fixed bottom plate 109 is fixedly connected with an air supply mechanism 2 for conveying the flue gas in a fire scene to the outside. The air supply mechanism 2 comprises an air supply channel 201, the top end of the air supply channel 201 is fixedly connected with a rotating motor 112, the rotating motor 112 is in transmission connection with a rotating water supply pipe 104 through a transmission gear 111, the transmission gear 111 is divided into two pieces in the embodiment, one piece is movably connected with the output end of the rotating motor 112, one piece is fixedly connected with the rotating water supply pipe 104, and the two pieces of gears are mutually vertical and meshed, so that when the rotating motor 112 rotates, the rotating water supply pipe 104 can be driven to rotate, and meanwhile, the air supply channel 201 is subjected to heat insulation treatment, so that the rotating motor 112 above the air supply channel keeps a lower temperature, and the damage of the rotating motor 112 is prevented. An internal temperature sensor 202 is fixedly connected to the inner side of the air duct 201, and the internal temperature sensor 202 is electrically connected to the annular atomizing nozzle 110. One end of the air duct 201 is fixedly connected with an air-feeding electric fan 203, when the temperature in the air duct 201 is too high, the annular atomizing nozzle 110 is opened to generate fine water mist, so as to prevent the air-feeding electric fan 203 from being damaged due to high temperature, and meanwhile, the electrical structure of the air-feeding electric fan 203 needs to be subjected to waterproof treatment. One end of the air-feeding electric fan 203 is fixedly connected with a pressurizing air-receiving cylinder 204, and the pressurizing air-receiving cylinder 204 is in a beam-closing structure in the embodiment, so that the speed of air flowing through the pressurizing air-receiving cylinder is improved, and the exhaust efficiency is improved.

When the utility model is used, the set temperature and dust concentration are input into the exhaust fan, and when the environmental temperature and dust concentration change, the exhaust fan can automatically take a response.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
