[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 4 In an embodiment of the present invention, a high-temperature resistant fire-fighting smoke exhaust motor includes a mounting plate 1, a control mechanism, a cooling mechanism and an air guide mechanism. A mounting frame 3 is installed on one end surface of the mounting plate 1, and a motor body 2 is installed inside the mounting frame 3. The output end of the motor body 2 passes through the mounting plate 1 and is arranged on a side of the mounting plate 1 away from the mounting frame 3. A protective frame 4 for protecting the motor body 2 is provided on the mounting frame 3. A heat insulation layer is provided inside the protective frame 4 and the mounting plate 1. A second through hole 16 is opened at the center of one end of the protective frame 4 away from the mounting plate 1.

[0030] The control mechanism is arranged on the protection frame 4 and is used to move the protection frame 4. In normal use, the protection frame 4 is opened to facilitate normal heat dissipation of the motor body 2. In the event of a fire, the protection frame 4 is covered on the motor body 2 to provide heat insulation protection for the motor body 2.

[0031] The cooling mechanism is disposed on the protection frame 4 , and is used to cool the interior of the protection frame 4 when the protection frame 4 is covered on the motor body 2 .

[0032] The wind guide mechanism is arranged on the protection frame 4 , and is used to collect wind to pass through the second through hole 16 when the protection frame 4 is opened, and to move wind toward the side wall of the protection frame 4 when the protection frame 4 is covered on the motor body 2 .

[0033] The control mechanism includes a controller 7, which is installed on the inner wall of the protective frame 4. Two symmetrically arranged fixing plates 18 are installed at one end of the side wall of the protective frame 4 away from the mounting plate 1.

A temperature sensor 17 for real-time measurement of air temperature is installed on the end of the fixing plate 18 away from the mounting plate 1.

[0034] When in use, the temperature sensor 17 transmits the measured temperature data to the controller 7. When the temperature measured by the temperature sensor 17 is lower than the set value, the controller 7 controls the electric telescopic rod 19 to start. The output end of the electric telescopic rod 19 pushes the fixed plate 18 to move, and the fixed plate 18 drives the protective frame 4 to move, opening the protective frame 4 to expose the motor body 2 to the air, thereby facilitating heat dissipation of the motor body 2.

[0035] When the temperature measured by the temperature sensor 17 is higher than the set value, the controller 7 controls the electric telescopic rod 19 to start, and the output end of the electric telescopic rod 19 drives the fixed plate 18 to move, and the fixed plate 18 drives the protective frame 4 to move, and the protective frame 4 is covered on the motor body 2 to prevent the high-temperature smoke from being released from the motor body 2, thereby preventing the temperature of the motor body 2 from rising.

[0036] The cooling mechanism includes a cooling frame 6, which is installed on the inner wall of the protection frame 4. The interior of the cooling frame 6 is filled with cooling water. A semiconductor refrigeration plate 5 for cooling the water inside the cooling frame 6 is installed on the side wall of the protection frame 4 inside the cooling frame 6.

[0037] When the protection frame 4 is covered on the motor body 2 , the semiconductor refrigeration sheet 5 is started, and the semiconductor refrigeration sheet 5 quickly cools and lowers the temperature of the water inside the cooling frame 6 , thereby providing heat dissipation protection for the motor body 2 .

[0038] The air guide mechanism includes a fixing ring 11, which is arranged on a side of the protective frame 4 away from the mounting plate 1. A first through hole 12 is opened at the center of the fixing ring 11, and the center points of the first through hole 12 and the second through hole 16 are on the same straight line. The diameter of the fixing ring 11 is larger than the diameter of the second through hole 16, and the diameter of the first through hole 12 is smaller than the diameter of the second through hole 16. A plurality of fixing rods 8 are installed in a circular array at one end of the protective frame 4 away from the mounting plate 1. The end of the fixing rod 8 away from the protective frame 4 is rotatably connected to a sliding frame 9 through a hinge. A sliding plate 10 is slidably connected to the inner wall of the sliding frame 9. The end of the sliding plate 10 away from the fixing rod 8 is rotatably connected to the side wall of the fixing ring 11 through a hinge. A driving component for moving the fixing ring 11 is provided on the mounting frame 3.

[0039] The driving assembly includes a fixing column 15 used in conjunction with the second through-hole 16, the fixing column 15 is installed at one end of the mounting frame 3 away from the mounting plate 1, the diameter of the fixing column 15 is the same as the second through-hole 16, a fixing block 14 is installed at one end of the fixing column 15 away from the mounting frame 3, the diameter of the fixing block 14 is smaller than the second through-hole 16, and the diameter of the fixing block 14 is larger than the first through-hole 12, a plurality of elastic ropes 13 for pulling the fixing ring 11 to move are installed at one end of the fixing column 15 away from the mounting frame 3, the elastic ropes 13 are arranged around the fixing block 14, and one end of the elastic rope 13 away from the fixing column 15 passes through the second through-hole 16 and is installed on the fixing ring 11.

[0040] When the protective frame 4 is opened, the fixing column 15 is away from the second perforation 16, and the elastic rope 13 pulls the fixing ring 11 to move. Under the action of the hinge, the fixing ring 11 drives the sliding plate 10 and the sliding frame 9 to swing, so that the end of the sliding plate 10 away from the fixing rod 8 swings toward the second perforation 16, and the wind is directed to the second perforation 16 through the sliding frame 9 and the sliding plate 10.

[0041] When the protective frame 4 is covered on the motor body 2, the fixing column 15 passes through the second through hole 16, the fixing column 15 drives the fixing block 14 to move, and the fixing block 14 pushes the fixing ring 11 to move. Under the action of the hinge, the fixing ring 11 drives the sliding plate 10 and the sliding frame 9 to swing, so that the end of the sliding plate 10 away from the fixing rod 8 swings to the side away from the second through hole 16, and the wind is guided to the side wall of the protective frame 4 through the sliding frame 9 and the sliding plate 10 to prevent hot wind from invading the motor body 2.

[0042] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
