Description

Technical Field

[0001] The utility model relates to the technical field of submersible motors, in particular to a submersible motor capable of reducing the temperature rise of a motor rotor. Background Art

[0002] Submersible motors are electric motors used specifically for submersible equipment. They are usually installed in submarines, submersible equipment or underwater mechanical equipment to provide power to drive the equipment underwater. Submersible motors are waterproof, pressure-resistant and highly efficient, and can work reliably in underwater environments. These motors can be powered by batteries or other power sources, enabling submersible equipment to perform various tasks underwater, such as exploration, scientific research, underwater engineering, etc.

[0003] In the prior art, since the stator is in direct contact with the motor casing, the temperature can be discharged through the motor casing more quickly when the temperature rises. However, there is a certain gap between the rotor and the stator. When the rotor heats up, the heat needs to be conducted to the casing through the air, resulting in slow heat conduction. Once the rotor temperature rises, the magnetism will decrease, and the overall performance of the motor will decrease, reducing its service life. In view of this, we propose a submersible motor that reduces the temperature rise of the motor rotor. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and to provide a submersible motor capable of reducing the temperature rise of the motor rotor, thereby solving the problem of slow heat conduction speed of the rotor.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a submersible motor for reducing the temperature rise of a motor rotor, comprising a motor housing, a mounting block fixedly connected to the outer surface of the motor housing, bolts for fixing are arranged on the mounting block, the interior of the motor housing is arranged to be hollow, a rotating shaft is rotatably connected to the left inner wall of the motor housing, a rotor is sleeved on the outer surface of the rotating shaft, a mounting ring is fixedly connected to the inner wall of the motor housing, an inner gear ring is sleeved on the inner wall of the mounting ring, a second rotating shaft is arranged inside the motor housing, a fan blade is fixedly connected to the left end of the second rotating shaft, and a drive assembly is arranged on the second rotating shaft.

[0006] Preferably, the driving assembly includes a gear, which is fixedly connected to the right end of the second rotating shaft, the outer surface of the gear is meshingly connected to the inner gear ring, the outer surface of the second rotating shaft is rotatably sleeved with a mounting plate, the outer surface of the rotating shaft is fixedly connected to a fixing ring, and the side surface of the mounting plate close to the fixing ring is fixedly connected to the fixing ring.

[0007] Preferably, a heat conducting sheet is provided on the left side surface of the motor housing, and the right side surface of the heat conducting sheet penetrates into the interior of the motor housing.

[0011] Preferably, a stator is fixedly connected to the inner wall of the motor housing.

[0012] Preferably, heat dissipation fins are fixedly connected to the outer surface of the motor housing.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) The submersible motor for reducing the temperature rise of the motor rotor, when the submersible motor starts to work, the rotating shaft rotates, and after the rotating shaft rotates, the driving assembly is used to cooperate with the internal gear ring to drive the second rotating shaft to rotate, and after the second rotating shaft rotates, the fan blades are synchronously driven to rotate. The rotation of the fan blades generates air flow, and the flowing air is used to cool the rotor. At the same time, the mounting ring provides stable support for the internal gear ring. Through the above structure, when the submersible motor is working, the fan blades can be automatically driven to rotate, thereby promoting internal air flow, and the air flow is used to drive the heat on the surface of the rotor, so that the temperature of the rotor is maintained within a relative installation range.

After the rotating shaft 5 rotates, the driving component is used to cooperate with the internal gear ring 7 to drive the second rotating shaft 9 to rotate. After the second rotating shaft 9 rotates, the fan blades 10 are synchronously driven to rotate. After the fan blades 10 rotate, air flow is generated, and the flowing air is used to cool the rotor 8. At the same time, the mounting ring 6 provides stable support for the internal gear ring 7. Through the above structure, when the submersible motor is working, the fan blades 10 can be automatically driven to rotate, thereby promoting internal air flow, and using air flow to drive the heat on the surface of the rotor 8, so that the temperature of the rotor 8 is maintained within a relatively installed range.

[0024] Furthermore, the driving assembly includes a gear 11, which is fixedly connected to the right end of the second rotating shaft 9, and the outer surface of the gear 11 is meshed with the inner gear ring 7. The outer surface of the second rotating shaft 9 is rotatably sleeved with a mounting plate 12, and the outer surface of the rotating shaft 5 is fixedly connected with a fixing ring 13, and the side surface of the mounting plate 12 close to the fixing ring 13 is fixedly connected to the fixing ring 13. The left surface of the motor housing 1 is provided with a heat conducting sheet 4, and the right side surface of the heat conducting sheet 4 penetrates into the interior of the motor housing 1. The inner wall of the motor housing 1 is fixedly connected with a heat conducting plate 14, and the shape of the heat conducting plate 14 is adapted to the gap of the heat conducting sheet 4.

When rotating, the fixing ring 13 will be used to drive the mounting plate 12 to rotate synchronously. When the mounting plate 12 rotates, the second rotating shaft 9 will be driven to rotate synchronously. Since the inner gear ring 7 is fixedly installed and the gear 11 is meshed with the inner gear ring 7, when the second rotating shaft 9 rotates, the gear 11 will be driven to rotate synchronously. After the gear 11 rotates, the fan blade 10 will be driven to rotate synchronously by the second rotating shaft 9. After the fan blade 10 rotates, the air flows to the left. After the hot air flows, it enters the gap between the heat conducting sheet 4 and contacts with the heat conducting sheet 4 and the heat conducting plate 14.

[0025] Working principle: When the submersible motor starts to work, the rotating shaft 5 rotates. After the rotating shaft 5 rotates, the driving component is used to cooperate with the inner gear ring 7 to drive the second rotating shaft 9 to rotate. After the second rotating shaft 9 rotates, the fan blades 10 are driven to rotate synchronously. After the fan blades 10 rotate, air flow is generated, and the flowing air is used to cool the rotor 8. At the same time, the mounting ring 6 provides stable support for the inner gear ring 7. When the rotating shaft 5 rotates, the fixing ring 13 is used to drive the mounting plate 12 to rotate synchronously. When the mounting plate 12 rotates, the second rotating shaft 9 is driven to rotate synchronously. Since the inner gear ring 7 is fixedly installed and the gear 11 is meshed with the inner gear ring 7, all when the second rotating shaft 9 rotates, the gear 11 is driven to rotate synchronously. After the gear 11 rotates, the fan blades 10 are driven to rotate synchronously by the second rotating shaft 9. After the fan blades 10 rotate, the air flows to the left. After the hot air flows, it enters the gap of the heat conducting plate 4 and contacts with the heat conducting plate 4 and the heat conducting plate 14. The heat conducting plate 14 and the heat conducting plate 4 absorb heat and discharge it.
