Description
Technical Field
[0001] The utility model relates to the technical field of motors, in particular to a dry-wet dual-purpose motor. Background Technique
[0002] A motor is an electromagnetic device that realizes the conversion or transmission of electrical energy based on the law of electromagnetic induction. It consists of components such as a stator, a rotor, an end cover, and bearings. By inputting electrical energy, a rotating magnetic field is generated inside the motor, driving the rotor to rotate, thereby converting electrical energy into mechanical energy. It is widely used in many fields such as industrial production, transportation, and household appliances. It is an indispensable power device in modern society. There are various types of motors, including DC motors, AC motors, etc. Different types have differences in performance, characteristics, and application scenarios. In the wide application of motors, the heat dissipation problem has always been a key factor affecting the performance and lifespan of motors. Especially in some special usage scenarios, such as those that require working underwater and on land, the heat dissipation methods of traditional motors often have limitations.
[0003] For motors working underwater, common heat dissipation methods mostly rely on the heat conduction of the motor's own materials. However, this method has a low heat dissipation efficiency and is difficult to meet the heat dissipation requirements during long-term underwater operation. It is easy to cause the motor to overheat, affecting its normal operation and even shortening its service life.
[0004] For motors used on land, the fan air-cooling method is usually adopted for heat dissipation. However, this method cannot function in the underwater environment, and when the motor switches from underwater to land operation, due to the inflexible switching of heat dissipation methods, it also poses challenges to the stable operation of the motor. In the structural design of traditional motors, the consideration for adapting to two different heat dissipation environments, underwater and on land, is not comprehensive enough, and it is often impossible to achieve efficient heat dissipation in both environments, thus restricting the application range and working efficiency of the motor.
[0005] Therefore, we propose a dry-wet dual-purpose motor. Content of the Utility Model
[0006] The purpose of the present utility model is to provide a dry-wet dual-purpose motor to solve the problems mentioned in the above background technology. For motors operating underwater, common heat dissipation methods mainly rely on the heat conduction of the motor's own materials. However, this method has a low heat dissipation efficiency and is difficult to meet the heat dissipation requirements during long-term underwater operation, easily leading to overheating of the motor, affecting its normal operation and even shortening its service life. Motors used on land usually adopt the method of air cooling with a fan for heat dissipation. But this method cannot function in an underwater environment, and when the motor switches from underwater to land operation, due to the inflexible switching of the heat dissipation method, it also poses challenges to the stable operation of the motor. In the structural design of traditional motors, insufficient consideration is given to adapting to two different heat dissipation environments on land and water, and often it is impossible to achieve efficient heat dissipation in both environments, thus limiting the application range and working efficiency of the motor.

[0030] Please refer to Figures 1 - 5 As shown, this embodiment is a wet and dry dual-purpose motor, including: a motor body 1, an underwater heat dissipation structure 2 is provided on the outer side of the motor body 1, the underwater heat dissipation structure 2 can dissipate heat when the motor body 1 is used underwater, a sealing cover structure 4 is provided on the front surface of the underwater heat dissipation structure 2, the sealing cover structure 4 can be sealed when used underwater, a sealing mounting part 5 is provided on the motor body 1 and at the back side, a sealing sleeve 6 is provided inside the sealing mounting part 5, and a heat dissipation fan 7 is provided inside the sealing sleeve 6. When working underwater, the heat generated inside the motor is quickly transmitted to the outermost heat dissipation housing 23 through the heat conduction ring 21 and the heat dissipation fins 22. Since the whole motor is immersed in water, the high heat capacity and good heat conduction performance of water can quickly take away the heat, thus effectively preventing the motor from overheating when working underwater. This design greatly improves the working stability and continuous operation time of the motor in the underwater environment.
[0031] When working on land, the sealing cover structures 4 and sealing sleeves 6 at the front and rear ends of the motor body 1 can be rotated and removed, and the internal cooling fan 7 is started to cooperate with the cooling fins 22 for blowing and cooling. This active air-cooling method can quickly dissipate the heat generated by the motor and meet the cooling requirements during land operation.
[0032] In addition, through this flexible switching of water-land cooling methods, the application scenarios of the motor are greatly expanded, enabling it to adapt to more complex and changeable working environments, and improving the versatility and practicality of the motor.
[0033] The underwater cooling structure 2 includes a heat conduction ring 21, which is fixed on the outer surface of the motor body 1. A number of cooling fins 22 are provided on the outer side of the heat conduction ring 21, and heat dissipation outer shells 23 are provided at the joints of the number of cooling fins 22.
[0034] First sealing threads 3 are provided on the outer surface of the motor body 1 near the front and on the inner side wall of the heat dissipation outer shell 23 near the outer side.
[0035] The sealing cover structure 4 includes a sealing cover body 41. A number of pulling blocks 42 are provided on the front of the sealing cover body 41, and second sealing threads 43 are provided on the outer side wall of the sealing cover body 41. The second sealing threads 43 are connected to the first sealing threads 3.
[0036] The cooling fan 7 is fixed on the back side wall of the motor body 1 and is connected and fixed by bolts.
[0037] The sealing sleeve 6 is inserted and used inside the sealing installation part 5, and the connection relationship between the two is the same as the connection relationship between the sealing cover structure 4 and the first sealing thread 3.
[0038] Working principle:
[0039] When the motor body 1 is in an underwater working environment, electromagnetic conversion and mechanical operation inside the motor body 1 will inevitably generate heat. In this process, the heat conduction ring 21 tightly wrapped around the outer layer of the motor body 1 plays a key role. Since the heat conduction ring 21 is made of materials with high thermal conductivity, such as copper or aluminum, etc., it can quickly absorb the heat generated by the motor body 1.
[0040] After the heat is absorbed by the heat conduction ring 21, it will quickly conduct along the internal microstructure of the heat conduction ring 21 to the cooling fins 22 that are tightly connected to it. These cooling fins 22 are evenly distributed between the heat conduction ring 21 and the outermost heat dissipation outer shell 23, increasing the contact area with the heat conduction medium (water). The cooling fins 22 usually have a large surface area and good heat exchange characteristics, and can effectively transfer the heat from the heat conduction ring 21 to the outermost heat dissipation outer shell 23 of the motor body 1.
[0041] Since the entire motor body 1 is immersed in water, and water being an excellent heat conductor can quickly carry away the heat at the outermost heat dissipation housing 23. The high heat capacity of water means it can absorb a large amount of heat while its own temperature rises relatively little. The process of heat transfer from the housing of the motor body 1 to the water is mainly achieved through heat convection. The flowing water continuously renews the part in contact with the housing and continuously carries away the heat, thus forming an efficient heat dissipation cycle.
[0042] Experiments have shown that when the motor body 1 operates continuously at a certain power underwater, the heat generated raises the temperature of the heat conduction ring 21 to 80 °C. This heat is quickly conducted to the heat dissipation fins 22, and the temperature of the heat dissipation fins 22 also rises to around 75 °C accordingly. The surrounding water can always maintain a relatively low temperature, such as around 20 °C, due to continuous flow and renewal. The heat is transferred from the heat dissipation fins 22 to the heat dissipation housing 23, causing a slight rise in the water temperature. However, due to the flow of water and its huge heat capacity, it can continuously and effectively absorb heat, ensuring that the temperature of the motor body 1 does not rise excessively and remains within a safe operating range.
[0043] When the motor body 1 needs to work on land, the sealing cover structures 4 and the sealing sleeves 6 at the front and rear ends of the motor body 1 can be rotated and removed. The internal heat dissipation fan 7 is started to cooperate with the heat dissipation fins 22 for blowing heat dissipation. This active air-cooling method can quickly dissipate the heat generated by the motor and meet the heat dissipation requirements during land operation. The threaded connection design of the sealing cover not only ensures the sealing performance in the underwater environment but also enables it to be conveniently removed on land.
[0044] After the sealing cover structures 4 and the sealing sleeves 6 are removed, the internal heat dissipation fan 7 starts to operate. The heat dissipation fan 7 is usually controlled by the internal circuit of the motor body 1 and adjusts its rotation speed according to the operating state of the motor body 1 and the feedback of the temperature sensor.
[0045] When the fan rotates, the generated air flow directly blows towards the heat dissipation fins 22. The flow of the air flow accelerates the air exchange on the surface of the heat dissipation fins 22 and carries away the heat on the fins. At the same time, the air flow generated by the fan can also form a certain air duct inside the motor body 1, promoting the circulating flow of the air inside the motor body 1 and further improving the heat dissipation effect.
[0046] For example, when the motor body 1 operates at high load on land, the internal temperature rises relatively fast. The heat dissipation fan 7 rotates at a higher speed, and the strong wind generated quickly blows over the heat dissipation fins 22, carrying away the heat on the fins. At the same time, the circulation formed by the air flow inside the motor body 1 can discharge the hot air around the core components of the motor body 1 and introduce the cooler outside air, effectively reducing the overall internal temperature of the motor body 1 and ensuring the stable operation and performance of the motor body 1 on land.
[0047] This heat dissipation method that can be flexibly switched according to different working environments precisely meets the heat dissipation requirements of the motor body 1 underwater and on land, ensuring that the motor body 1 can maintain good working conditions and performance under various complex and changeable working conditions.
