Description

Technical Field

[0001] The utility model belongs to the technical field of motors and relates to a motor, in particular to a water-cooled motor. Background Art

[0002] A water-cooled motor is a motor device that uses water as a cooling medium. Water-cooled motors are suitable for high temperature environments and variable frequency speed regulation systems. They have a wide speed regulation range and can meet the needs of different working conditions. Water-cooled motors have brushless structures, excellent load characteristics, good low-speed performance, large starting torque, and small starting current, which make them highly reliable and durable.

[0003] Traditional water-cooled motors achieve a cooling effect by spraying liquid on the casing, but the spraying of liquid can cause corrosion to the motor casing, and has high requirements for the sealing of the motor casing. Summary of the invention

[0004] The purpose of the utility model is to provide a corrosion-resistant water-cooled motor in view of the above-mentioned problems existing in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a water-cooled motor, characterized in that it includes a motor body with a rotor and a stator inside, a shell is provided on the motor body, both ends of the shell are provided with covers, a power shaft is provided on the rotor, a plurality of movably connected support rods are symmetrically provided on the power shaft, the ends of the support rods are provided with rotating wheels, a hose is provided on the inner wall of the shell, the rotating wheel conflicts with the hose, and a spiral cooling pipe is provided inside the shell, and downwardly extending extension pipes are provided at the ends of the hose and the spiral cooling pipe.

[0006] In the above-mentioned water-cooled motor, a spring is provided on each of the support rods, and one side of the spring is fixed on the power shaft.

[0007] In the above-mentioned water-cooled motor, the cover includes a front cover and a rear cover, a support bearing is provided at the center of the rear cover, and a plurality of fixing bolts are evenly distributed in a ring on the cover.

[0008] In the above-mentioned water-cooled motor, an observation opening is provided on the casing.

[0009] In the above-mentioned water-cooled motor, a one-way valve is provided on the extension pipe.

[0010] Compared with the prior art, the water-cooled motor achieves motor cooling by arranging a spiral cooling tube inside the casing. The cooling liquid does not contact the motor body, preventing the cooling liquid from corroding the motor parts. The movably connected support rod squeezes the hose through centrifugal force, and the speed of the water flow is adjusted by the speed of rotation, thereby adapting to the problem of high temperature at high speed and preventing excessive squeezing of the hose at low speed. A one-way valve is used to prevent the internal liquid from flowing back, so that slow flow and cooling can be achieved even at low speed. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0017] like Figure 1 , 2 As shown in Figures 3 and 4, the water-cooled motor includes a motor body 4 with a rotor 14 and a stator 9 inside, a shell 8 is provided on the motor body 4, and covers 15 are provided at both ends of the shell 8. A power shaft 7 is provided on the rotor 14, and a plurality of movably connected support rods 11 are symmetrically provided on the power shaft 7. A rotating wheel 10 is provided at the end of the support rod 11. A hose 12 is provided on the inner wall of the shell 8, and the rotating wheel 10 conflicts with the hose 12. A spiral cooling pipe 17 is provided inside the shell 8, and extension pipes 16 extending downward are provided at the ends of the hose 12 and the spiral cooling pipe 17. When the power shaft 7 rotates, the support rod 11 squeezes the hose 12 under the action of centrifugal force, and the effect of a peristaltic pump is achieved by squeezing the hose 12, and the liquid is passively extracted and transported to the spiral cooling pipe 17, thereby absorbing heat to achieve cooling.

[0018] Preferably, a spring 13 is provided on the support rod 11, one side of the spring 13 is fixed on the power shaft 7, and the spring 13 controls the support rod 11 to squeeze the hose 12, thereby reducing excessive squeezing of the hose 12. When the rotation speed is faster, the squeezing force is increased, the water flow speed is processed, and efficient cooling is achieved.

[0019] Preferably, the cover 15 includes a rear cover 6 and a rear cover 2 , a support bearing 18 is provided at the center of the rear cover 2 , and a plurality of fixing bolts 1 are evenly distributed in a ring shape on the cover 15 .

[0020] Preferably, an observation opening 3 is provided on the housing 8 .
