[0003] A patent application with the publication number CN108768076A discloses a water-cooled motor, including a casing and a water-cooling component, which takes away the heat on the casing through water circulation, including a water-cooling cavity arranged on the casing, a water inlet pipe component communicated with the water-cooling cavity, and a water outlet pipe component communicated with the water-cooling cavity. A drain branch pipe is arranged on the water outlet pipe component, and an opening and closing valve is detachably connected to the drain branch pipe. By setting the water-cooling component, the heat on the casing can be quickly absorbed, and the cooling effect is good; the temperature inside the entire motor can be kept constant during this process, improving the working efficiency of the motor.

[0032] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0033] Such as Figures 1 to 2As shown in the figure, a water-cooled motor according to an embodiment of the present invention includes a housing 1; end covers 2 are bolted to the openings at both ends of the housing 1; a rotor is rotatably installed in the middle of the housing 1, and the rotating shaft of the rotor rotatably penetrates through one of the end covers 2; a water-cooling pipe network 3 is arranged inside the outer wall of the housing 1; the interfaces at both ends of the water-cooling pipe network 3 respectively penetrate through the end covers 2 on both sides; the interfaces at both ends of the water-cooling pipe network 3 are connected to a cooling tower through pipes; a water scale cleaning unit is arranged at the water inlet end of the water-cooling pipe network 3; the water scale cleaning unit includes a tee pipe 4; the water inlet end of the water-cooling pipe network 3 is bolted to one end interface of the tee pipe 4; the other end interface of the tee pipe 4 is connected to the water outlet end of the cooling tower through a pipe; a storage tank 5 is fixedly connected to the top interface of the water-cooling pipe network 3; cleaning steel balls are stored inside the storage tank 5; a release assembly is arranged in the middle of the storage tank 5, and the release assembly is used to release the cleaning steel balls into the tee pipe 4; when the water-cooled motor is running, the cooling water in the external cooling tower is transported through a pipe into the water-cooling pipe network 3 inside the housing 1, and the high temperature generated inside the water-cooled motor exchanges heat with the cooling water flowing inside the water-cooling pipe network 3, so that the water-cooled motor dissipates heat and cools down; when the water-cooled motor runs for a long time, water scale will adhere to the inner wall of the water-cooling pipe network 3. Excessive water scale will not only affect the heat exchange efficiency, but also block the water-cooling pipe network 3 and affect the circulation of the cooling water; therefore, it is necessary to clean the water-cooling pipe network 3; when dredging the water-cooling pipe network 3, the water-cooled motor is turned off, and the cooling water circulation of the water-cooled motor is kept open. When the cooling water in the cooling tower is transported to the water-cooling pipe network 3 inside the housing 1, when the cooling water passes through the tee pipe 4, the cleaning steel balls stored inside the storage tank 5 are released into the tee pipe 4 by the release assembly, and the cleaning steel balls are carried by the cooling water through the water-cooling pipe network 3. The cleaning steel balls collide and rub against the inner wall of the water-cooling pipe network 3, so that the water scale adhering to the inner wall of the water-cooling pipe network 3 is broken and falls off, and the fallen water scale debris is carried out of the water-cooling pipe network 3 by the cooling water; thus, not only the situation of disassembling the water-cooled motor to clean the water scale is avoided, the dredging and cleaning efficiency is improved, but also the cooling effect and operation safety of the water-cooled motor are improved.

[0034] As Figures 2 to 4As shown, the release component includes a first electric push rod 6; a plurality of first electric push rods 6 are evenly and fixedly connected to the outer periphery of the top of the storage tank 5; a lifting plate 7 is slidably mounted on the top surface of the storage tank 5; the top end of the first electric push rod 6 is fixedly connected to the bottom surface of the lifting plate 7; a sliding sleeve is fixedly connected to the bottom surface of the middle part of the lifting plate 7; the sliding sleeve in the middle of the lifting plate 7 slidably penetrates through the top of the storage tank 5; a vertical rod 8 is arranged inside the sliding sleeve of the lifting plate 7; a conical plug column 9 is fixedly connected to the bottom end of the vertical rod 8; the bottom of the plug column 9 can contact the inner wall of the bottom of the storage tank 5; a motor 10 is fixedly connected to the middle of the top surface of the lifting plate 7; the outer ring of the vertical rod 8 is rotationally matched with the inner ring of the sliding sleeve of the lifting plate 7; the rotating shaft of the motor 10 is fixedly connected to the top end of the vertical rod 8; a spiral blade 11 is fixedly connected to the outer ring of the top of the plug column 9; the gap between adjacent blades of the spiral blade 11 is larger than the diameter of the cleaning steel balls; a baffle 12 is fixedly connected to the top surface of the plug column 9; a notch 13 is formed in the outer ring of the baffle 12; the notch 13 is communicated with the top inlet of the spiral blade 11; the width and length of the notch 13 are both larger than the diameter of the cleaning steel balls; when cleaning is not carried out, the cleaning steel balls are stored inside the storage tank 5. At this time, the first electric push rod 6 is in a contracted state, so that the lifting plate 7 is close to and contacts the top surface of the storage tank 5, so that the plug column 9 contacts the inner wall of the bottom of the storage tank 5, seals the material outlet of the storage tank 5, and blocks the cleaning steel balls from entering the tee pipe 4, thereby avoiding the situation that the cleaning steel balls enter the water-cooled pipe network 3 when the water-cooled motor is running normally; when cleaning is required, the first electric push rod 6 pushes the lifting plate 7 to rise, drives the vertical rod 8 and the plug column 9 to rise, so that the plug column 9 is separated from the inner wall of the bottom of the storage tank 5. At this time, the motor 10 drives the vertical rod 8 to rotate, drives the plug column 9 to rotate, drives the spiral blade 11 and the baffle 12 to rotate, and the cleaning steel balls inside the storage tank 5 enter the spiral blade 11 from the notch 13 on the baffle 12. The falling rate of the cleaning steel balls is controlled through the notch 13 on the baffle 12, so that the cleaning steel balls enter the spiral blade 11 one by one, reducing the probability of blockage of the cleaning steel balls. Moreover, the spiral blade 11 rotates, improving the feeding efficiency and stability of the cleaning steel balls; thus, the cleaning steel balls are stably released into the tee pipe 4, reducing the situation of blockage of the cleaning steel balls.

[0035] As Figure 4As shown, a ring cavity 14 is formed inside the plug post 9; a plurality of convex strips are fixedly connected to the outer circle of the ring cavity 14 evenly; a plurality of impact balls 15 are arranged around the middle of the ring cavity 14; a first spring 16 is fixedly connected between the top surface and the bottom surface of the impact ball 15 and the top surface and the bottom surface of the ring cavity 14 respectively; during operation, when the plug post 9 rotates, the centrifugal force generated causes the impact balls 15 inside the ring cavity 14 to move outward, causing the first spring 16 to stretch. When the impact balls 15 collide with the outer wall or the convex strips of the ring cavity 14, the impact balls 15 rebound. With the elastic force of the first spring 16 and the centrifugal force of rotation, the impact balls 15 continuously impact the inner wall of the ring cavity 14, thereby reducing the probability of blockage of the cleaning steel balls in the spiral blade 11 and improving the smoothness of the falling of the cleaning steel balls.

[0036] As Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, a recycling unit is arranged between the water inlet end of the water cooling pipe network 3 and the water inlet end of the cooling tower; the recycling unit includes a three-way valve 17; a pair of three-way valves 17 are connected in series between the water inlet end of the water cooling pipe network 3 and the water inlet end of the cooling tower; a recycling box 18 is connected between the bottom interfaces of the two three-way valves 17; a vertical plate 19 is fixedly connected to the bottom surface of the recycling box 18 near one side of the water cooling pipe network 3; a recycling drawer 20 is slidably installed inside the recycling box 18 near one side of the water cooling pipe network 3, and the recycling drawer 20 is fixedly connected to the outer wall of the recycling box 18 through bolts; a sliding plate 21 is hinged inside the recycling box 18 near one side of the water cooling pipe network 3, and a torsion spring is arranged at the hinged position of the sliding plate 21; a plurality of through slots are formed in the sliding plate 21 evenly; the bottom of the sliding plate 21 is located above the vertical plate 19; a filter plate 22 is fixedly connected to the inside of the recycling box 18 near one side of the water cooling pipe network 3; a blanking port is formed in the middle of the bottom surface of the recycling box 18, and a sealing plate is bolted inside the blanking port; a plurality of second springs 23 are fixedly connected to the top surface of the vertical plate 19 evenly; the top ends of the plurality of second springs 23 are fixedly connected to a support rod 24; the top of the support rod 24 can contact the bottom of the sliding plate 21; during operation, the fallen scale debris and cleaning steel balls are carried out of the water cooling pipe network 3 by the cooling water and enter the recycling box 18 through the three-way valve 17. The cooling water and the cleaning steel balls fall onto the sliding plate 21, causing the sliding plate 21 to rotate downward, causing the support rod 24 to move downward, causing the second springs 23 to be compressed to generate elastic force, pushing the sliding plate 21 to rotate upward, causing the sliding plate 21 to vibrate. The scale in the cooling water passes through the through slots on the sliding plate 21 and falls into the recycling drawer 20 for storage, while the cleaning steel balls slide to the middle of the recycling box 18 for storage along the sliding plate 21 and are blocked by the filter plate 22. After the cooling water passes through the filter plate 22, it is discharged from the recycling box 18 and flows back to the cooling tower; thus, the separation of the cooling water, the cleaning steel balls and the scale is realized.

[0037] As Figure 1 , Figure 5 and Figure 8 shown, the three-way valve 17 includes a valve body 171; a receiving groove 172 is formed on the top surface of the inner cavity of the valve body 171; a second electric push rod 173 is fixedly connected to the top surface of the valve body 171; the piston rod of the second electric push rod 173 slidably penetrates the top wall of the valve body 171; a switching column 174 is slidably installed inside the receiving groove 172; the top of the switching column 174 is in a circular plate shape, and the bottom of the switching column 174 is in a semi-circular arc plate shape; the top surface of the switching column 174 is fixedly connected to the bottom end of the piston rod of the second electric push rod 173; the concave surface of the bottom of the switching column 174 faces the housing 1; when cleaning is not carried out, the second electric push rod 173 is in an extended state, and the second electric push rod 173 pushes the switching column 174 to slide downward, so that the switching column 174 blocks and seals the outlet at the bottom of the valve body 171, preventing cooling water from entering the recovery tank 18; when cleaning is carried out, the second electric push rod 173 drives the switching column 174 to rise in height, blocking the outlet of the valve body 171 facing the cooling tower, so that the cooling water, cleaning steel balls and scale can smoothly enter the recovery tank 18; moreover, the structure of the switching column 174 reduces the probability of blockage of the three substances in different states, namely cooling water, cleaning steel balls and scale, inside the valve body 171, and improves the fluidity of the three-way valve 17.

[0038] As Figure 1 , Figure 5 , Figure 9 and Figure 10As shown in the figure, an oscillation component is connected between the bottom interface of one of the three-way valves 17 close to the outer shell 1 and the water inlet end of the recovery tank 18; the oscillation component includes a tank body 25; the bottom of the tank body 25 is conical; a corrugated ring sleeve 26 is fixedly connected to the inner wall of the tank body 25; the top and bottom of the ring sleeve 26 are respectively communicated with the top and bottom of the tank body 25; a pair of brackets 27 are fixedly connected to the inner wall of the bottom of the tank body 25; a rotating rod 28 is rotatably installed in the middle of a pair of the brackets 27; an inclined blade 29 is fixedly connected to the outer circle in the middle of the rotating rod 28; the top end of the rotating rod 28 is fixedly connected with a corrugated rotating seat 30; the rotating seat 30 is sleeved inside the ring sleeve 26, and the rotating seat 30 is of a hollow structure; the distance between the inner wall of the ring sleeve 26 and the outer wall of the rotating seat 30 is greater than the diameter of the cleaning steel ball; a plurality of convex rings 31 are evenly fixedly connected to the inner wall of the ring sleeve 26; when the cleaning steel balls clean the scale on the inner wall of the water-cooling pipe network 3, the surface of the cleaning steel balls is liable to stick to the scale, making the recovered cleaning steel balls unable to be directly used and needing to be cleaned before use; the scale, the cleaning steel balls and the cooling water enter the inside of the tank body 25, pass through the channel between the ring sleeve 26 and the rotating seat 30 and enter the bottom of the tank body 25, pushing the inclined blade 29 to rotate, driving the rotating rod 28 and the rotating seat 30 to rotate, so that the cleaning steel balls collide inside the channel between the ring sleeve 26 and the rotating seat 30, making the cleaning steel balls impact the inside of the ring sleeve 26, the outer wall of the rotating seat 30 and the convex rings 31, thereby making the scale on the surface of the cleaning steel balls break away, and then improving the cleaning degree of the recovered cleaning steel balls and facilitating the recycling and use of the cleaning steel balls.

[0039] Working principle: When the water-cooled motor runs, the cooling water in the external cooling tower is transported through the pipeline to the water-cooling pipe network 3 inside the outer shell 1, and the high temperature generated inside the water-cooled motor exchanges heat with the cooling water flowing inside the water-cooling pipe network 3, so that the water-cooled motor dissipates heat and cools down; at this time, cleaning steel balls are stored inside the storage tank 5, the first electric push rod 6 is in a contracted state, so that the lifting plate 7 approaches and contacts the top surface of the storage tank 5, making the plug column 9 contact the inner wall of the bottom of the storage tank 5, sealing the material outlet of the storage tank 5 and blocking the cleaning steel balls from entering the three-way pipe 4, avoiding the situation that the cleaning steel balls enter the water-cooling pipe network 3 when the water-cooled motor runs normally; the second electric push rod 173 is in an extended state, and the second electric push rod 173 pushes the switching column 174 to slide downward, so that the switching column 174 blocks and seals the outlet at the bottom of the valve body 171, blocking the cooling water from entering the recovery tank 18;

[0040] After the water-cooled motor runs for a long time, scale will adhere to the inner wall of the water-cooling pipe network 3. Excessive scale will not only affect the heat exchange efficiency, but also block the water-cooling pipe network 3 and affect the circulation of the cooling water; therefore, it is necessary to clean the water-cooling pipe network 3; turn off the water-cooled motor and keep the cooling water circulation of the water-cooled motor open;

[0041] The first electric push rod 6 pushes the lifting plate 7 to rise in height, driving the vertical rod 8 and the plug column 9 to rise in height, so that the plug column 9 is separated from the inner wall of the bottom of the storage tank 5. At this time, the motor 10 drives the vertical rod 8 to rotate, driving the plug column 9 to rotate, driving the spiral blade 11 and the baffle 12 to rotate. The cleaning steel balls inside the storage tank 5 enter the spiral blade 11 from the notch 13 on the baffle 12. When the plug column 9 rotates, the centrifugal force generated causes the impact balls 15 inside the annular cavity 14 to move outward, stretching the first spring 16. When the impact balls 15 collide with the outer wall or the convex strip of the annular cavity 14, the impact balls 15 rebound. With the elastic force of the first spring 16 and the centrifugal force of rotation, the impact balls 15 continuously impact the inner wall of the annular cavity 14, reducing the probability of blockage of the cleaning steel balls in the spiral blade 11; the cleaning steel balls are released into the inside of the three-way pipe 4, and the cleaning steel balls are carried by the cooling water through the water-cooled pipe network 3. The cleaning steel balls collide and rub against the inner wall of the water-cooled pipe network 3, causing the scale attached to the inner wall of the water-cooled pipe network 3 to break and fall off. The fallen scale debris is carried by the cooling water out of the water-cooled pipe network 3;

[0042] At this time, the second electric push rod 173 drives the switching column 174 to rise in height, blocking the valve body 171 towards the outlet of the cooling tower, so that the scale, cleaning steel balls and cooling water enter the inside of the tank body 25, enter the bottom of the tank body 25 through the channel between the annular sleeve 26 and the rotating seat 30, and push the inclined blade 29 to rotate, driving the rotating rod 28 and the rotating seat 30 to rotate, so that the cleaning steel balls collide inside the channel between the annular sleeve 26 and the rotating seat 30, causing the cleaning steel balls to collide with the inside of the annular sleeve 26, the outer wall of the rotating seat 30, and the convex ring 31, so that the scale on the surface of the cleaning steel balls falls off; the scale, cleaning steel balls and cooling water enter the recovery box 18. The cooling water and the cleaning steel balls fall onto the sliding plate 21, causing the sliding plate 21 to rotate downward, causing the supporting rod 24 to move downward, compressing the second spring 23 to generate elastic force, pushing the sliding plate 21 to rotate upward, causing the sliding plate 21 to vibrate. The scale in the cooling water passes through the through groove on the sliding plate 21 and falls into the recovery drawer 20 for storage, while the cleaning steel balls slide down along the sliding plate 21 to the middle of the recovery box 18 for storage and are blocked by the filter plate 22. After the cooling water passes through the filter plate 22, it is discharged from the recovery box 18 and flows back to the cooling tower, realizing the separation of the cooling water, cleaning steel balls and scale;

[0043] Thus, not only the situation of disassembling the water-cooled motor for cleaning the scale is avoided, the efficiency of dredging and cleaning is improved, but also the cooling effect and operation safety of the water-cooled motor are improved.

Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
