[0028] Specifically, as shown in the figure: one end of the T-shaped movable rod 206 is fixedly connected to a limiting plate to prevent the T-shaped movable rod 206 from detaching from the limiting hole 203 and the movable groove 103.

[0029] In one embodiment, rotating columns 207 are fixedly connected to the bottom ends of the other side of the two lifting plates 205.

[0031] In one embodiment, the angle-adjustable component 3 includes a tunnel jet fan body 301. Two rotating shafts 302 are fixedly connected to both sides of one end of the tunnel jet fan body 301. Support rods 303 are fixedly connected to both sides of the middle portion of the tunnel jet fan body 301. T-shaped support blocks 304 are embedded in the inner cavities of the other ends of the two support rods 303 via bearings. Motor plates 305 are fixedly connected to the tops of the two T-shaped support blocks 304. The inner cavities of the two T-shaped support blocks 304 are... A threaded rod 306 is embedded in the bearing. The top of each threaded rod 306 is connected to a forward and reverse motor 307. The output ends of the two forward and reverse motors 307 are fixedly connected to the center of the top of the two threaded rods 306. The surfaces of the two forward and reverse motors 307 are fixedly connected to one side of the two motor plates 305. T-shaped support blocks 308 are threadedly fitted onto the surfaces of the two threaded rods 306. Limiting plates 309 are fixedly fitted onto the bottom and middle parts of the surfaces of the two threaded rods 306.

[0032] Specifically, as shown in the figure: T-shaped support block 304 is installed inside the support rod 303 by bearing, and one end of T-shaped support block 308 is installed on the side of the top plate 201 by bearing. The tilt angle between them can be adjusted according to the rotation of threaded rod 306, thereby realizing the adjustment of the tilt angle of the tunnel jet fan body 301; the side of the positive and negative motor 307 is fixedly connected to the surface of motor plate 305 to prevent the positive and negative motor 307 from shaking during operation and affecting the normal operation of the tunnel jet fan.

[0033] In one embodiment, the surfaces of two T-shaped movable rods 206 located at the bottom are movably embedded in the inner cavities of two movable slots 103, the surfaces of two T-shaped movable rods 209 located at the bottom are movably embedded in the inner cavities of two limiting holes 102, and the surfaces of two rotating columns 207 are movably embedded in the inner cavities at both ends of the push plate 108.

[0034] Specifically, as shown in the figure: the rotating column 207 is movably embedded in the inner cavity of the push plate 108 to limit the movement of the push plate 108, preventing the threaded rod 106 from driving the push plate 108 to rotate and affecting the normal operation of the jet fan for this tunnel. At the same time, it does not affect the rotation of the rotating column 207 when the lifting plate 205 is folded or extended.

[0035] In one embodiment, the surfaces of the other ends of the two rotating shafts 302 are mounted on the top of the two support plates 210 by bearings, and the surfaces of one end of the two T-shaped support blocks 308 are mounted on the middle part of both sides of the top plate 201 by bearings.

[0036] Specifically, as shown in the figure: one end of the T-shaped support block 308 is installed on the side of the top plate 201 through a bearing, and the tilt angle can be adjusted according to the rotation of the threaded rod 306, thereby realizing the adjustment of the tilt angle of the tunnel jet fan body 301.

[0037] Working principle: The tunnel jet fan is pushed to the required position by the handle 202 and the brake caster 101 and connected to the external power supply equipment. The external power supply equipment provides power to the first forward and reverse motor 107, the tunnel jet fan body 301 and the second forward and reverse motor 307. The external controller is associated with and controls the first forward and reverse motor 107, the tunnel jet fan body 301 and the second forward and reverse motor 307.

[0038] The external controller starts the forward and reverse motor 107. The output end of the forward and reverse motor 107 drives the threaded rod 106 to rotate. Since the threaded rod 106 is threadedly connected to the push plate 108, the rotating threaded rod 106 drives the push plate 108 to move towards the support block 104. The push plate 108 pushes the bottom end of the lifting plate 205 towards the limiting hole 102. The lifting plate 205 and the lifting plate 208 gradually extend. Since the length of the lifting plate 205 and the lifting plate 208 is fixed, the top plate 201 is forced to rise vertically, thus raising the height of the tunnel jet fan body 301. The external controller starts the forward and reverse motor 107 in the opposite direction. The lifting plate 205 and the lifting plate 208 gradually fold, forcing the top plate 201 to fall vertically, thus lowering the height of the tunnel jet fan body 301.

[0039] This design allows the height of the jet fan in the tunnel to be adjusted as needed.

[0040] The external controller starts the second forward and reverse motor 307. The output end of the second forward and reverse motor 307 drives the second threaded rod 306 to rotate. Since the second T-shaped support block 308 is threadedly connected to the second threaded rod 306, and the position of the second T-shaped support block 308 is fixed, the rotating second threaded rod 306 moves up and down in the inner cavity of the second T-shaped support block 308. The top of the second threaded rod 306 pulls the first T-shaped support block 304 to rise or fall in the horizontal position, thereby adjusting the tilt angle of the tunnel jet fan body 301.

[0041] This design allows the angle of the jet fan used in the tunnel to be adjusted as needed.

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
