[0022] In this embodiment: the air entering the fixed box 202 is filtered by the filter plate 203 to prevent debris from entering the fixed box 202 and causing blockage. The motor 204 drives the rotating shaft 205 and the fan blades 206 to rotate, and the fan blades 206 generate wind force.

[0023] Specifically, Figure 1-Figure 8 As shown, two T-shaped slots 207 are respectively provided on the bottom surfaces of the two support frames 201, and T-shaped blocks 208 are respectively slidably installed on the inner walls of the multiple T-shaped slots 207.

The air inlets of the two air outlet pipes 210 are fixedly installed with hoses 212 respectively. The other ends of the two hoses 212 are fixedly passed through the bottom surface of the fixed box 202 and extend to the inside of the fixed box 202.

[0026] In this embodiment, the hose 212 is provided so that the air outlet pipe 210 can move freely without being affected.

[0027] Specifically, Figure 1-Figure 8 As shown, two support frames 201 are fixedly installed with two limit rods 213 close to each other on the side, and a limit hole is provided on the side of the movable plate 214.

[0028] In this embodiment, the movable plate 214 is limited by the limiting rod 213, and the inclined slot 215 drives the internal fixed column 216 to move, thereby driving the movable frame 209 to move.

[0029] Specifically, Figure 1-Figure 8As shown, the lower end of the rotating shaft 205 rotates through the inner wall of the lower end of the fixed box 202 and extends to the bottom of the fixed box 202. A fixing bar 217 is fixedly installed on the outer wall of the lower end of the rotating shaft 205. A cylinder 218 is fixedly installed on the bottom surface of the other end of the fixing bar 217. A through groove 219 is opened through the top surface of the movable plate 214. The outer wall of the cylinder 218 is slidably connected with the inner wall of the through groove 219.

[0030] In this embodiment, the rotating shaft 205 drives the fixing bar 217 to rotate, and the fixing bar 217 drives the cylinder 218 to rotate on the inner wall of the through groove 219, thereby driving the moving plate 214 to reciprocate.

[0031] The cooling mechanism 3 is arranged on one side of the air outlet pipe 210. The cooling mechanism 3 includes a water spray pipe 310 located on one side of the air outlet pipe 210. A fixing box 304 is arranged above the water spray pipe 310. A piston plate 306 is slidably installed on the inner wall of the fixing box 304. The cooling mechanism 3 is used for spraying water to cool the reducer body 1.

[0032] Specifically, Figure 1-Figure 8 As shown, support bars 301 are fixedly installed on both sides of the fixed box 202, and two water tanks 302 are fixedly installed on the top surfaces of the multiple support bars 301. The top surfaces of the two water tanks 302 are respectively provided with water inlets 303, and connecting pipes 305 are fixedly installed on the sides of the two water tanks 302.

[0033] In this embodiment, the water tank 302 is used to contain cooling water to provide cooling water for the device.

[0034] Specifically, Figure 1-Figure 8 As shown, two fixed boxes 304 and two piston plates 306 are provided, the bottom surfaces of the two fixed boxes 304 are fixedly connected to the top surface of the support frame 201 on one side, the other ends of the two connecting tubes 305 are respectively fixed through the top surfaces of the two fixed boxes 304 and extend to the inside of the fixed boxes 304, and a one-way valve 1 is respectively fixedly installed on the two connecting tubes 305.

[0035] In this embodiment: by setting a fixed box 304 and a piston plate 306, the piston plate 306 slides on the inner wall of the fixed box 304, so that cooling water is drawn from the water tank 302 to the fixed box 304 through the connecting pipe 305, and a one-way valve is set, so that cooling water can only be drawn from the fixed box 304 and cannot be transported in the reverse direction.

[0036] Specifically, Figure 1-Figure 8 As shown, push rods 307 are fixedly installed on the sides of the two piston plates 306, and the other ends of the two push rods 307 slide through the inner wall of one side of the fixed box 304 and extend to the outside of the fixed box 304. The other ends of the two push rods 307 are fixedly installed with fixed blocks 308, and the bottom surfaces of the two fixed blocks 308 are fixedly connected to the top surface of the movable plate 214.

[0037] In this embodiment, by providing the fixed block 308 , when the movable plate 214 moves, the piston plate 306 is driven to move by the fixed block 308 and the push rod 307 , thereby absorbing and discharging cooling water.

[0038] Specifically, Figure 1-Figure 8 As shown, two water spray pipes 310 are provided, and multiple nozzles 311 are fixedly installed through the outer walls of the lower ends of the two water spray pipes 310, and two fixed sleeves 309 are fixedly installed on the outer walls of the two water spray pipes 310. The sides of the multiple fixed sleeves 309 are fixedly connected to the sides of the two movable frames 209 respectively. The water inlet ends of the two water spray pipes 310 are installed with hoses 312 through one-way valves 312, and the other ends of the two hoses 312 are fixedly installed through the sides of the two fixed boxes 304 and extend to the inside of the fixed boxes 304.

[0039] In this embodiment: cooling water is sprayed toward the reducer body 1 and the heat sink 101 through the provided water spray pipe 310 and the nozzle 311, so as to effectively cool the reducer body 1. The provided one-way valve 2 enables the fixing box 304 to only discharge cooling water from the hose 2 312, and cannot absorb gas and cooling water.

[0040] The specific solution is as follows: start the motor 204 to drive the rotating shaft 205 and the fan blades 206 to rotate, and the wind generated by the rotation of the fan blades 206 is transported from the hose 1 212 to the air outlet 210 through the fixed box 202, and then blown from the air outlet 211 to the heat sink 101 and the reducer body 1, and at the same time, the rotating shaft 205 drives the fixed bar 217 and the cylinder 218 to rotate, and the cylinder 218 slides in the through groove 219 and drives the movable plate 214 to move back and forth, and the movable plate 214 drives the fixed column 216 and the movable frame 209 to move back and forth through the two inclined grooves 215, and the movable frame 209 drives the air outlet 210 and the air outlet 211 to move back and forth, so that the air outlet 211 performs comprehensive air blowing cooling on the reducer body 1 and the heat sink 101, and blows away the heat on the reducer body 1. The reducer body 1 is effectively cooled and dissipated to increase its service life. At the same time, the movable frame 209 drives the water spray pipe 310 and the nozzle 311 to move back and forth, and when the movable plate 214 moves back and forth, it drives the fixed block 308 and the push rod 307 to move. The push rod 307 drives the piston plate 306 to move back and forth in the fixed box 304, so that the fixed box 304 absorbs cooling water from the water tank 302 through the connecting pipe 305, and then sprays it from the nozzle 311 to the reducer body 1 and the heat sink 101 through the hose 2 312 and the water spray pipe 310, so that the reducer body 1 is cooled and cooled by the cooling water. In a high temperature environment, the cooling water can still effectively cool the reducer body 1 to ensure that the temperature of the reducer body 1 is not easily damaged by excessively high temperature, thereby increasing its service life.
