Abstract
Description
Technical Field
[0001] The utility model relates to the field of motors, in particular to a fully enclosed waterproof motor. Background Art
[0002] With the demand and development of underwater engineering, the application scope of waterproof motors is becoming more and more extensive. Waterproof motors mainly reduce the possibility of water droplets entering the base along the output shaft and damaging the stator and rotor by installing waterproof bearings on the output shaft.
[0003] However, the waterproof structure of the current fully enclosed waterproof motor simply relies on a waterproof bearing to waterproof the main shaft and the motor housing. Once the waterproof bearing is worn or even damaged, the waterproof effect cannot be guaranteed to ensure the normal operation of the motor. Moreover, the friction between the main shaft and the waterproof bearing is large during high-speed rotation, which easily leads to a high temperature of the waterproof bearing and is prone to failure and damage. Therefore, a fully enclosed waterproof motor is proposed. Utility Model Content
[0004] In view of the above problems existing in the existing fully enclosed waterproof motor, the present utility model is proposed.
[0005] Therefore, the purpose of the utility model is to provide a fully enclosed waterproof motor to solve the problems raised by the background technology.
[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0007] A fully enclosed waterproof motor comprises a motor body and a main shaft, wherein a waterproof shell is fixedly provided at the front end of the motor body, waterproof bearings are fixedly embedded on both sides of the waterproof shell, the main shaft passes through the interior of the waterproof shell and is rotatably connected to the waterproof shell through the waterproof bearings; a coolant is provided inside the waterproof shell, and heat-conducting columns are fixedly provided on the top and bottom of the waterproof shell, one end of each heat-conducting column extends to the interior of the waterproof shell, and the other end of the heat-conducting column extends to the outside of the waterproof shell.
[0008] Preferably, the waterproof shell and the outer shell of the motor body are integrally formed.
[0009] Preferably, a mounting seat is fixedly provided at the bottom of the motor body, and mounting bolts are provided on both sides of the mounting seat.
[0010] Preferably, a heat-conducting strip is fixedly provided at one end of the heat-conducting column located inside the waterproof shell, and a plurality of dispersed holes are opened on the surface of the heat-conducting strip.
[0011] Furthermore, the heat-conducting columns and the heat-conducting strips are arranged in a distribution pattern, and both the heat-conducting columns and the heat-conducting strips are made of aluminum alloy.
[0012] Preferably, a plurality of evenly distributed disturbance blades are fixedly disposed around the shaft wall of the main shaft and located inside the waterproof shell.
[0013] In the above technical solution, the technical effects and advantages provided by the utility model are:
[0014] The utility model is provided with a waterproof shell and waterproof bearings arranged on both sides of the waterproof shell. Firstly, the waterproof shell can shield and protect the connection between the main shaft and the motor body, reducing the possibility of rainwater entering. At the same time, the main shaft is rotatably connected to the waterproof shell through two waterproof bearings, so that the main shaft and the waterproof shell have a double waterproof effect, reducing the possibility of rainwater entering through the main shaft and the waterproof shell, and improving the fully enclosed waterproof effect of the motor body.
[0015] The utility model uses a coolant and a heat-conducting column arranged inside the waterproof shell. The coolant can cool the waterproof bearings on both sides, thereby avoiding high surface temperatures of the waterproof bearings and reducing the probability of damage. At the same time, the coolant can prevent damage and also reduce the probability of frictional heating. In addition, the heat-conducting column can exchange the temperature of the coolant with the external temperature, thereby ensuring the cooling effect of the coolant on the waterproof bearings.
[0016] The utility model has disturbance blades arranged on the main shaft, and the main shaft can drive the disturbance blades to rotate during rotation. The disturbance blades can stir the coolant inside the waterproof shell, thereby improving the contact effect between the coolant and the heat-conducting column and the waterproof bearing.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0024] The utility model embodiment discloses a fully enclosed waterproof motor.
[0025] The utility model provides Figure 1-2 A fully enclosed waterproof motor shown in the figure includes a motor body 1 and a main shaft 2. A mounting seat 6 is fixedly provided at the bottom of the motor body 1, and mounting bolts 7 are provided on both sides of the mounting seat 6. The mounting seat 6 is connected to the screw holes preset on the mounting surface through the mounting bolts 7, so that the motor body 1 is fixedly installed. A waterproof shell 3 is fixedly provided at the front end of the motor body 1. The waterproof shell 3 and the outer shell of the motor body 1 are integrally processed and arranged. Waterproof bearings 4 are fixedly embedded on both sides of the waterproof shell 3. The main shaft 2 passes through the interior of the waterproof shell 3 and is rotatably connected to the waterproof shell 3 through the waterproof bearings 4. The waterproof shell 3 can shield and protect the connection between the main shaft 2 and the motor body 1, reducing the possibility of rainwater entering. At the same time, the main shaft 2 is rotatably connected to the waterproof shell 3 through two waterproof bearings 4, so that the main shaft 2 and the waterproof shell 3 play a double waterproof role, reducing the possibility of rainwater entering through the main shaft 2 and the waterproof shell 1, and improving the fully enclosed waterproof effect of the motor body 1.
[0026] In order to cool the waterproof bearing 3, Figure 1-2 As shown, the interior of the waterproof shell 3 is provided with a coolant, and the top and bottom of the waterproof shell 3 are fixedly provided with heat-conducting columns 5, one end of the heat-conducting columns 5 extends to the interior of the waterproof shell 3, and the other end of the heat-conducting columns 5 extends to the outside of the waterproof shell 3. A heat-conducting strip 8 is fixedly provided at one end of the heat-conducting column 5 located inside the waterproof shell 3, and a plurality of dispersion holes 9 are opened on the surface of the heat-conducting strip 8. The dispersion holes 9 can increase the contact area between the coolant and the heat-conducting strip 8. The heat-conducting columns 5 and the heat-conducting strip 8 are distributed at 90°, and the heat-conducting columns 5 and the heat-conducting strip 8 are both made of aluminum alloy. The heat-conducting columns 5 and the heat-conducting strip 8 can exchange the internal and external temperatures of the waterproof shell 3, so as to reduce the temperature of the coolant.
[0027] Finally, in order to increase the fluidity of the coolant, such as Figure 2-3 As shown, a plurality of evenly distributed disturbance blades 10 are fixedly arranged around the shaft wall of the main shaft 2 and located inside the waterproof shell 3. The main shaft 2 can drive the disturbance blades 10 to rotate during rotation, thereby stirring the coolant inside the waterproof shell 3, thereby improving the contact effect between the coolant and the heat-conducting column 5 and the waterproof bearing 3.
