When the rotary reducer on the fixed seat 5 moves to the bottom of the spray end 6, the spray end 6 sprays water outward through the nozzle 7, so that the rotary reducer is subjected to a water spray test, so as to detect the waterproofness of the rotary reducer.

The rotation of the first lead screw 11 causes the lead screw nut 12 installed in meshing engagement on its outside to move after passing through the limit of the slide groove 10. The movement of the lead screw nut 12 will drive the rotary reducer on the fixed seat 5 to move through the mounting plate 2, so that it can move to the top of the water collecting chamber 17 and the bottom of the spray end 6, so that the rotary reducer on the fixed seat 5 can start the water spray test.

[0029] like Figure 2As shown, an air outlet cavity 32 is embedded in the body 1, and a plurality of air outlet holes 33 are arranged on the air outlet cavity 32.

A fan 29 is fixedly installed on the inner bottom of the body 1, and the air inlet end of the fan 29 extends to the outside of the body 1 through the pipe body, and the air outlet end of the fan 29 extends to the inside of the heating box 30 through the pipe body. A ventilation pipe 34 is arranged on the heating box 30, and one end of the ventilation pipe 34 extends to the inside of the air outlet cavity 32. When the rotary reducer on the fixed seat 5 is turned over, the first motor 15 rotates in the opposite direction so that it can drive the turned rotary reducer on the fixed seat 5 to return to its original position through the mounting plate 2.

The air outside the machine body 1 is sucked in through the pipe body, and the gas is transported to the heating box 30 through the pipe body installed at its air outlet end. As the electric heating element 31 arranged around the inside of the heating box 30 is started, it will heat the air entering the heating box 30. As the outside air continues to enter, the heated air in the heating box 30 will enter the inside of the air outlet chamber 32 through the ventilation pipe 34, and the warm air is evenly transported outward through the multiple groups of air outlet holes 33 provided on the air outlet chamber 32, so that the warm air can evenly dry the rotary reducer after being turned over. In this way, the drying work of the surface of the rotary reducer after the water spray test can be faster and more effective, which reduces the workload of the staff, improves the drying efficiency and effect of the surface of the rotary reducer, and enhances the practicability of the waterproof detection device.
[0030] Working principle: the fixing seat 5 can be rotatably installed on the top of the mounting plate 2 through the shaft body 4 and the mounting seat 3. The fixing seat 5 is used to install and fix the rotary reducer to be detected. When the rotary reducer on the fixing seat 5 moves to the bottom of the spray end 6, the spray end 6 sprays water outward through the nozzle 7, so that the rotary reducer undergoes a water spray test, so as to detect the waterproofness of the rotary reducer. When the rotary reducer on the fixing seat 5 is driven by the mounting plate 2 to move to the bottom of the spray end 6, the first water pump 9 fixedly installed on the top of the liquid storage tank 8 is started, which absorbs water in the liquid storage tank 8 through the liquid inlet end and transports the water to the spray end 6 through the liquid outlet end. Finally, it sprays downward through the multiple groups of nozzles 7 fixedly installed at the bottom of the spray end 6, so that the rotary reducer located below the spray end 6 The speed reducer is subjected to a water spray test so that the water resistance of the rotary speed reducer can be tested. When the rotary speed reducer is subjected to a water spray test, the water sprayed from the nozzle 7 will slide into the water collecting chamber 17 provided in the body 1 for storage after falling on the rotary speed reducer. With the start of the second water pump 19 in the protective shell 18, its liquid inlet end will absorb the water stored in the water collecting chamber 17 and re-transport the water to the inside of the liquid storage tank 8 through the water pipe 20 installed at its liquid outlet end, so that the device can recycle the test water when in use. After the rotary speed reducer is installed and fixed to the top of the fixing seat 5, the first motor 15 fixedly installed in the shell 13 is started, and its output end drives the first lead screw 11 rotatably installed in the two sets of slide grooves 10 to rotate through the second sprocket 16, the chain and the first sprocket 14. The first lead screw 11 rotates so that the lead screw nut 12 meshedly installed on its outside moves after passing through the limit of the slide groove 10. The movement of the lead screw nut 12 will drive the rotary reducer on the fixed seat 5 to move through the mounting plate 2, so that it can move to the top of the water collecting chamber 17 and the bottom of the spray end 6, so that the rotary reducer on the fixed seat 5 can start the water spray test. After the rotary reducer has undergone a long period of water spray test, the second motor 27 fixedly installed in the outer shell 21 is started, and its output end drives the rotating rod 24 to rotate through the second gear 28 and the first gear 26 meshed therewith. The rotation of the rotating rod 24 causes the second sprocket 25 fixedly installed on its outside to drive the rotating shaft 22 to rotate through the chain and the first sprocket 23. The rotation of the rotating shaft 22 will drive the fixed seat 5 through the shaft body 4. The rotary reducer on the fixing seat 5 is flipped over so that the water on the rotary reducer can fall into the water collecting chamber 17 due to gravity. After the rotary reducer on the fixing seat 5 is flipped over, the first motor 15 rotates in the opposite direction so that it can drive the flipped rotary reducer on the fixing seat 5 to return to its original position through the mounting plate 2. When it returns to its original position, the fan 29 is started, and its air inlet end absorbs the air outside the body 1 through the pipe body, and transports the gas to the heating box 30 through the pipe body installed at its air outlet end. With the start-up of the electric heating element 31 arranged around the inside of the heating box 30, it will heat the air entering the heating box 30. With the continuous entry of external air, the heated air in the heating box 30 will enter the inside of the air outlet chamber 32 through the ventilation pipe 34.The warm air is evenly delivered outward through the multiple groups of air outlet holes 33 provided on the air outlet cavity 32, so that the warm air can evenly dry the rotary reducer after flipping, so that the surface drying work of the rotary reducer after the water spray test can be more efficient and effective, reducing the workload of the staff, improving the drying efficiency and effect of the rotary reducer surface, and enhancing the practicality of the waterproof detection device.
