Description

Technical Field

[0001] The present invention belongs to the field of motors, and specifically relates to a waterproof motor. Background Art

[0002] A motor refers to an electromagnetic device that realizes the conversion or transmission of electrical energy based on the law of electromagnetic induction. Motors can be roughly classified into waterproof motors that work underwater for a long time, cold-proof motors that work in alpine regions for a long time, etc. according to the usage environment.

[0003] Motors that work underwater for a long time need to have excellent anti-corrosion and waterproof functions, so they are called waterproof motors. For a waterproof motor, the components on the outer surface of the motor, including the front and rear end covers and the outer shell, are of a seamless structure. A dynamic sealing mechanism is provided between the motor shaft and the shaft hole. Since the possible gaps or channels inside and outside the waterproof motor are blocked by the sealing mechanism, a reliable waterproof effect can be obtained.

[0004] Traditional waterproof motors are underwater for a long time. Plankton or waterweed spores in the water flow will attach to the outer shell of the motor. As they grow, eventually a layer of moss will grow on the outer surface of the motor or the surface will be covered with parasitic organisms. These coverings will not only erode the outer shell of the motor, causing the outer shell of the motor to gradually break and losing waterproof performance and impact resistance; and waterproof motors are basically fully sealed. The heat dissipation depends on the contact heat transfer between the outer surface and the water to maintain a low-temperature environment inside the motor. If the motor surface is fully covered, the heat dissipation function will be severely blocked, easily causing the temperature inside the motor to be too high, reducing the service life of the motor. And when the temperature of the motor outer shell rises, it is very likely to scorch the coverings on the outer surface of the motor, resulting in stronger adhesion, and finally a thicker accumulation of attachments on the motor outer shell, which is not only difficult to clean later, but also the heat dissipation effect becomes worse and worse.

[0005] Therefore, the present invention provides a waterproof motor. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background art.

[0007] The technical solution adopted by the present invention to solve its technical problems is: A waterproof motor described in the present invention includes a sealed outer shell and a motor body inside the sealed outer shell. The sealed outer shell is arranged in a horizontally placed cylindrical shape. A plurality of moving grooves are opened on the outer surface of the sealed outer shell. The plurality of moving grooves are arranged in an annular equidistant manner. A slider is slidably clamped inside the moving groove. An isolation plate is fixedly connected to the outside of the slider. The plurality of isolation plates wrap the surface of the sealed outer shell. A power assembly is arranged outside the isolation plate. The power assembly is used to drive the isolation plate to slide;

[0008] By arranging a plurality of slidable isolation plates on the outer side of the sealed housing, during the operation of the waterproof motor, the power assembly drives the plurality of isolation plates to reciprocate on the outer side of the sealed housing. The slider is clamped in the moving groove, allowing the isolation plate to only slide horizontally. Since the isolation plate completely covers the outer side of the sealed housing, the reciprocating isolation plate can prevent the attachments in the water from staying on the outer side of the isolation plate, and the isolation plate is completely attached to the sealed housing, enabling the heat of the sealed housing to be exchanged and dissipated through the isolation plate and the external water flow. Through this setting, the waterproof motor can be stored underwater for a long time, and there will be no large amount of attachments adhering to the surface of the sealed housing, allowing the waterproof motor to normally exchange heat with water. At the same time, the reduction of attachments can also reduce the erosion of the attachments on the outer side of the waterproof motor.

[0009] Preferably, a protruding cover is fixedly connected to the front end of the sealed housing. A separation cover is sleeved on the outer side of the protruding cover. The rotor in the motor body is located in the middle of the inner side of the sealed housing. The end of the rotor is located inside the protruding cover, and a magnetic coupling seat is fixedly connected to the end of the rotor. A magnetic disk is fixedly connected to the side of the separation cover close to the protruding cover. A transmission head is fixedly connected to the middle of the side of the separation cover away from the protruding cover. In order for the waterproof motor to work underwater for a long time and prevent external water sources from entering the interior and causing damage, generally, a waterproof structure such as a sealing ring needs to be installed at the connection between the rotor and the sealed housing. However, it is difficult for the waterproof structure to maintain sealing after long-term use, and the sealing structure will rub against the rotor, resulting in power consumption. Through the setting of the magnetic coupling seat, when the rotor rotates, it drives the magnetic coupling seat to rotate. Under magnetic adsorption, it drives the magnetic disk and the separation cover to rotate. The external structure that needs to be driven is connected to the transmission head. It should be noted that the external transmission structure needs to be fixed additionally. For example, if an external propeller is connected, the outer side of the propeller needs to be rotationally clamped. In this way, the separation cover can be restricted outside the protruding cover for non-contact transmission. Under this design, the sealed housing and the protruding cover seal the motor body as a whole inside and do not come into contact with external water sources at all. This not only avoids the invasion of external water sources but also greatly improves the safety of the equipment underwater.

[0010] Preferably, the magnetic coupling seat is composed of a metal frustum and a plurality of magnetic blocks. The plurality of magnetic blocks are arranged in an annular and equidistant manner on the outer surface of the metal frustum. The magnetic poles of adjacent magnetic blocks facing the outside are opposite. The magnetic disk is also composed of a plurality of magnetic blocks. The plurality of magnetic rings are arranged on the inner wall of the side of the separation cover close to the protruding cover, and the arrangement method is the same as that of the magnetic coupling seat. The arrangement of the metal frustum and the magnetic blocks allows for a large adsorption surface between the magnetic coupling seat and the separation cover, which can transfer the magnetic ability to a greater extent. The staggered arrangement of the magnetic poles, compared with the design where all the magnetic stones have the same magnetic poles, each individual magnetic stone has an independent adsorption effect, preventing the magnetic coupling seat from easily moving relative to the magnetic disk. In this way, the rotational kinetic energy can be better transmitted.

[0011] Preferably, two symmetrically arranged repulsive seats are fixedly connected to the outer edge of the separation cover. The repulsive seats are made of magnetic material. One end of the isolation plate close to the repulsive seat is made of magnetic material, and the magnetic pole of the repulsive seat facing the repulsive seat is the same as the magnetic pole of the repulsive seat facing the isolation plate. A horizontal spring telescopic rod is fixedly connected between the slider and the wall of the moving groove. As the separation cover rotates, the ends of the two repulsive seats will continuously approach the ends of each isolation plate during the rotation. Under the action of magnetic repulsion, the isolation plate will be pushed away. During the repulsion process, the two do not come into contact. When the repulsive seat moves away, under the action of the spring telescopic rod, the slider and the isolation plate are pulled back, so that the isolation plate returns to its original position. Through this setting, the rotation of the separation cover is used to realize the repeated sliding process of multiple isolation plates, eliminating the need for additional driving electrical appliances, thereby reducing the manufacturing cost and the operation difficulty.

[0012] Preferably, a bent arm is fixedly connected to the rear end of the sealed housing. A support seat is fixedly connected to the bottom of the bent arm. The support seat is in a horizontal state and is located at the bottom of the sealed housing. The entire sealed housing is supported in a suspended state through the bent arm and the support seat, enabling the isolation plate to work properly. The wide support seat can stably support the entire sealed housing.

[0013] Preferably, a first steel cable is fixedly connected to the end of the isolation plate away from the separation cover. A cavity is formed inside the bent arm, and a hydraulic rod is fixedly connected to the cavity. The ends of multiple first steel cables are all fixedly connected to the end of the hydraulic rod. To make the movement of the isolation plate controllable, by shortening the hydraulic rod, multiple first steel cables can be pulled, and then the isolation plate can be pulled away from the separation cover. In this way, when the repulsive seat passes by the isolation plate, it will not push the isolation plate to move, and the waterproof motor can operate normally without losing energy due to pushing the isolation plate. When it is necessary to clean the surface of the isolation plate, extend the hydraulic rod to release the first steel cable. Under the action of the spring telescopic rod, the isolation plate returns to its original position, and then the repulsive seat can drive the isolation plate.

[0014] Preferably, an opening groove is formed at the top of the isolation plate. A metal plate is fixedly connected to the top surface of the isolation plate. A pulling assembly is arranged in the opening groove. The pulling assembly is used to pull the bottom of the metal plate when the isolation plate moves. To enhance the ability of the isolation plate to clean its outer surface, the top surface of the isolation plate is made into an elastic metal plate. During the movement of the isolation plate, the bottom surface of the metal plate is pulled by the pulling assembly. Since the metal plate has toughness and elasticity, it will concave inward during the pulling process and rebound under its own elastic action after the pulling ends, generating vibrations on the surface of the metal plate, which can more effectively remove surface attachments, thus ensuring the heat dissipation effect of the motor and improving its service life.

[0015] Preferably, the pulling assembly includes multiple steel cables 2, which are fixedly connected to the side of the metal plate facing the open groove, and the bottom of the steel cables 2 passes through the slider and is fixedly connected to the groove wall of the movable groove. During the translation of the isolation plate and the slider, the steel cables 2 are pulled, thereby pulling the metal plate downward, making the metal plate concave. When the isolation plate returns to its position, the metal plate rebounds and vibrates under the action of its own elasticity, thereby completing the shaking cleaning work. This arrangement realizes the pulling of the steel cables 2 by utilizing the sliding action of the isolation plate, and no additional electrical appliances are required.

[0016] Preferably, a plurality of limit rings arranged at equal distances are fixedly connected to the bottom of the open groove, and the plurality of steel cables 2 are gathered into two forked steel cables with multiple forks, the length of the forked steel cables depends on the longest steel cable 2, and each fork of the forked steel cables is fixedly connected to the metal plate, and an inner slide groove is provided at the bottom of the movable groove, and the inner slide groove is in the shape of an elongated strip, and the width of the inner slide groove is smaller than the width of the slider, and the ends of the two forked steel cables are fixedly connected to the bottom of the inner slide groove, and by merging the plurality of steel cables 2 into a forked steel cable, only the ends of the two forked steel cables need to pass through the slider to achieve the effect of transmission pulling, and the setting of the inner slide groove prevents the bottom of the forked steel cable from affecting the sliding of the slider, and the setting of the limit ring can limit the moving trajectory of the forked steel cable to prevent it from running around.

[0017] Preferably, an embedded rod is fixedly connected to one end of the transmission head close to the magnetic coupling seat, and the embedded rod passes through the external protruding cover and is slidably engaged with the external protruding cover, and the embedded rod is inserted into the end of the magnetic coupling seat and is rotatably engaged with the magnetic coupling seat. In order to improve the applicability of the equipment, another model is designed. This model allows the embedded rod to pass through the external protruding cover and the magnetic coupling seat, so that the separation cover is maintained on the outside of the external protruding cover. No external support is required, and the transmission still relies on magnetic transmission. Since the embedded rod is located in the middle position, it is difficult for foreign objects from the outside to invade it.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The waterproof motor described in the present invention is provided with a plurality of slidable isolation plates on the outer side of the sealed shell. During the operation of the waterproof motor, the plurality of isolation plates are driven by a power component to reciprocate on the outer side of the sealed shell. The slider is clamped in the movable groove so that the isolation plate can only slide horizontally. Since the isolation plate completely covers the outer side of the sealed shell, the reciprocating isolation plate prevents attachments in the water from staying on the outer side of the isolation plate, and the isolation plate and the sealed shell are completely fitted, so that the heat of the sealed shell can be exchanged and dissipated by the isolation plate and the external water flow. Through this arrangement, the waterproof motor can be stored underwater for a long time without a large amount of attachments attached to the surface of the sealed shell, so that the waterproof motor can exchange heat with water normally. At the same time, the reduction of attachments can also reduce the erosion of the attachments on the outer side of the waterproof motor.

[0020] 2. The waterproof motor described in the present invention, through the setting of the magnetic coupling seat, when the rotor rotates, it drives the magnetic coupling seat to rotate, and under magnetic adsorption, it drives the magnet disk and the separation cover to rotate. The structure that needs to be driven externally is connected to the transmission head. It should be noted that the external transmission structure needs to be fixed additionally. For example, if an external propeller is connected, the outer side of the propeller needs to be rotationally clamped, so that the separation cover can be restricted outside the protruding cover to perform contactless transmission. Under this design, the sealed housing and the protruding cover seal the motor body entirely inside and do not contact the external water source at all. This not only avoids the invasion of external water sources but also greatly improves the safety of the equipment when used underwater. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION

[0030] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0031] As Figures 1 to 5As shown in the figure, a waterproof motor according to an embodiment of the present invention includes a sealed housing 1 and a motor body inside the sealed housing 1. The sealed housing 1 is arranged in a horizontal cylindrical shape. A plurality of moving grooves 9 are formed on the outer surface of the sealed housing 1. The plurality of moving grooves 9 are arranged in an annular and equidistant manner. A slider 14 is slidably clamped inside the moving groove 9. An isolation plate 2 is fixedly connected to the outside of the slider 14. The plurality of isolation plates 2 wrap the surface of the sealed housing 1. A power assembly is arranged outside the isolation plate 2. The power assembly is used to drive the isolation plate 2 to slide.

[0032] During operation, in a traditional waterproof motor that is underwater for a long time, plankton or waterweed spores in the water flow will attach to the motor housing. As they grow, eventually a layer of moss will grow on the outer surface of the motor or the surface will be covered with parasitic organisms. These coverings will not only erode the motor housing, causing the motor housing to gradually break and losing waterproof performance and impact resistance; and the waterproof motor is basically fully sealed. Heat dissipation depends on heat exchange through contact between the outer surface and water to maintain a low-temperature environment inside the motor. If the motor surface is completely covered, the heat dissipation function will be severely blocked, easily causing the temperature inside the motor to be too high, reducing the service life of the motor. And when the temperature of the motor housing rises, it is very likely to scorch the coverings on the outer surface of the motor, resulting in stronger adhesion. Eventually, more and more thick attachments will accumulate on the motor housing, which is not only difficult to clean later, but also the heat dissipation effect will become worse and worse.

[0033] By arranging a plurality of slidable isolation plates 2 outside the sealed housing 1, during the operation of the waterproof motor, the power assembly drives the plurality of isolation plates 2 to reciprocate outside the sealed housing 1. The slider 14 is clamped in the moving groove 9, so that the isolation plate 2 can only slide horizontally. Since the isolation plate 2 completely covers the outside of the sealed housing 1, the reciprocating isolation plate 2 can prevent the attachments in the water from staying outside the isolation plate 2. And the isolation plate 2 is completely attached to the sealed housing 1, so that the heat of the sealed housing 1 can be exchanged and dissipated with the outside water flow through the isolation plate 2. Through this setting, the waterproof motor can be stored underwater for a long time, and there will be no large amount of attachments adhering to the surface of the sealed housing 1, enabling the waterproof motor to normally exchange heat with water. At the same time, the reduction of attachments can also reduce the erosion of the attachments on the outside of the waterproof motor.

[0034] As Figures 1 to 5 As shown in the figure, a protruding cover 11 is fixedly connected to the front end of the sealed housing 1. A separation cover 3 is sleeved outside the protruding cover 11. The rotor 10 in the motor body is located in the middle inside the sealed housing 1. The end of the rotor 10 is located inside the protruding cover 11, and a magnetic coupling seat 12 is fixedly connected to the end of the rotor 10. A magnetic disk is fixedly connected to the side of the separation cover 3 close to the protruding cover 11. A transmission head is fixedly connected to the middle of the side of the separation cover 3 away from the protruding cover 11.

[0035] During operation, in order for the waterproof motor to work underwater for a long time and prevent external water sources from entering the interior and causing damage, generally a waterproof structure such as a sealing ring needs to be installed at the connection between the rotor 10 and the sealing housing 1. However, it is difficult for the waterproof structure to maintain sealing after long-term use, and the sealing structure will rub against the rotor 10, resulting in power consumption. Through the setting of the magnetic coupling seat 12, when the rotor 10 rotates, it drives the magnetic coupling seat 12 to rotate, and under magnetic adsorption, it drives the magnet disk and the separation cover 3 to rotate. The external structure that needs to be driven is connected to the transmission head 4. It should be noted that the external transmission structure needs to be fixed additionally. For example, for an externally connected propeller, the outer side of the propeller needs to be rotationally clamped, so that the separation cover 3 can be restricted outside the protruding cover 11 for non-contact transmission. Under this design, the sealing housing 1 and the protruding cover 11 seal the motor body as a whole inside and do not come into contact with external water sources at all. This not only avoids the invasion of external water sources but also greatly improves the safety of the equipment when used underwater.

[0036] As Figures 1 to 5 shown, the magnetic coupling seat 12 is composed of a metal frustum and a plurality of magnetic blocks. The plurality of magnetic blocks are arranged at equal intervals in a ring on the outer surface of the metal frustum, and the magnetic poles of adjacent magnetic blocks facing the outside are opposite. The magnet disk is also composed of a plurality of magnetic blocks, and the plurality of magnetic rings are arranged on the inner wall of the separation cover 3 close to the protruding cover 11, and the arrangement method is the same as that of the magnetic coupling seat 12;

[0037] During operation, due to the arrangement of the metal frustum and the magnetic blocks, there can be a large adsorption surface between the magnetic coupling seat 12 and the separation cover 3, which can transfer the magnetic ability to a greater extent. And the staggered arrangement of the magnetic poles, compared with the design where all the magnetic stones have the same magnetic poles, each individual magnetic stone has an independent adsorption effect, so that the magnetic coupling seat 12 will not easily move relative to the magnet disk, and thus can better transfer the rotational kinetic energy.

[0038] As Figures 1 to 5 shown, two repulsion seats 6 are symmetrically fixed at the outer edge of the separation cover 3. The repulsion seats 6 are made of magnetic material. One end of the isolation plate 2 close to the repulsion seats 6 is made of magnetic material, and the magnetic pole of the repulsion seat 6 facing the repulsion seat 6 is the same as the magnetic pole of the repulsion seat 6 facing the isolation plate 2. A transverse spring telescopic rod 19 is fixed between the sliding block 14 and the groove wall of the moving groove 9;

[0039] During operation, as the separation cover 3 rotates, the ends of the two repulsion seats 6 will approach the ends of each isolation plate 2 continuously during the rotation process. Under the action of magnetic repulsion, the isolation plate 2 will be pushed away distantly. During the repulsion process, the two do not come into contact. When the repulsion seat 6 moves away, under the action of the spring telescopic rod 19, the slider 14 and the isolation plate 2 will be pulled back, so that the isolation plate 2 returns to its original position. Through this setting, the rotation of the separation cover 3 is utilized to realize the repeated sliding process of multiple isolation plates 2, without the need to use additional driving electrical appliances, thereby reducing the manufacturing cost and the operation difficulty.

[0040] As Figures 1 to 5 shown, a bent arm 8 is fixedly connected to the rear end of the sealing housing 1, and a support seat 5 is fixedly connected to the bottom of the bent arm 8. The support seat 5 is in a horizontal state and is located at the bottom of the sealing housing 1. During operation, the entire sealing housing 1 is supported in a suspended state through the bent arm 8 and the support seat 5, enabling the isolation plate 2 to work properly. The wide support seat 5 can stably support the entire sealing housing 1.

[0041] As Figures 1 to 5 shown, a first steel cable 7 is fixedly connected to one end of the isolation plate 2 away from the separation cover 3. A cavity is formed inside the bent arm 8, and a hydraulic rod is fixedly connected in this cavity. The ends of multiple first steel cables 7 are all fixedly connected to the end of the hydraulic rod;

[0042] During operation, in order to make the movement of the isolation plate 2 controllable, by shortening the hydraulic rod, multiple first steel cables 7 can be pulled, and then the isolation plate 2 can be pulled in the direction away from the separation cover 3. In this way, when the repulsion seat 6 passes by the isolation plate 2, it will not push the isolation plate 2 to move, and the waterproof motor can operate normally without losing energy due to pushing the isolation plate 2. When it is necessary to clean the surface of the isolation plate 2, extend the hydraulic rod to release the first steel cables 7. Under the action of the spring telescopic rod 19, the isolation plate 2 returns to its original position, and in this way, the repulsion seat 6 can drive the isolation plate 2.

[0043] As Figures 6 to 7 shown, an opening groove 18 is formed at the top of the isolation plate 2, a metal plate 17 is fixedly connected to the top surface of the isolation plate 2, and a pulling component is arranged in the opening groove 18. The pulling component is used to pull the bottom of the metal plate 17 when the isolation plate 2 moves;

[0044] During operation, in order to increase the ability of the isolation plate 2 to clean its outer surface, the top surface of the isolation plate 2 is made into an elastic metal plate 17. During the movement of the isolation plate 2, the bottom surface of the metal plate 17 is pulled by the pulling component. Since the metal plate 17 has toughness and elasticity, during the pulling process, it will concave inward, and after the pulling ends, it will rebound under its own elastic action, which can generate vibrations on the surface of the metal plate 17, and can more effectively remove the surface attachments, thereby ensuring the heat dissipation effect of the motor and improving the service life.

[0045] As shown Figures 6 to 7 in the figure, the pulling assembly includes a plurality of second steel cables 16, the second steel cables 16 are fixedly connected to one side of the metal plate 17 facing the opening groove 18, and the bottom of the second steel cables 16 passes through the slider 14 and is fixedly connected to the groove wall of the moving groove 9;

[0046] During operation, during the translation of the isolation plate 2 and the slider 14, since the second steel cables 16 are pulled, the metal plate 17 will be pulled downward, causing the metal plate 17 to be concave. When the isolation plate 2 returns to its position, the metal plate 17 will rebound under its own elastic action to generate vibration, thereby completing the shaking cleaning work. This setting realizes the pulling of the second steel cables 16 by driving the sliding action of the isolation plate 2, and no additional electrical appliances need to be set.

[0047] As shown Figures 6 to 7 in the figure, a plurality of equally spaced limiting rings 15 are fixedly connected to the bottom of the opening groove 18. A plurality of second steel cables 16 are assembled into two forked steel cables with a plurality of branches. The length of the forked steel cable depends on the longest second steel cable 16. Each branch of the forked steel cable is fixedly connected to the metal plate 17. An inner sliding groove 20 is opened at the bottom of the moving groove 9. The inner sliding groove 20 is strip-shaped, and the width of the inner sliding groove 20 is smaller than the width of the slider 14. The ends of the two forked steel cables are fixedly connected to the bottom of the inner sliding groove 20;

[0048] During operation, by combining a plurality of second steel cables 16 into a forked steel cable, only the ends of the two forked steel cables need to pass through the slider 14 to complete the effect of driving and pulling. The setting of the inner sliding groove 20 enables the bottom of the forked steel cable not to affect the sliding of the slider 14. The setting of the limiting ring 15 can limit the moving track of the forked steel cable and prevent it from running around randomly.

[0049] As shown Figures 3 to 5 in the figure, an embedded rod 13 is fixedly connected to one end of the transmission head 4 close to the magnetic coupling seat 12. The embedded rod 13 penetrates through the outer protruding cover 11 and is slidably clamped with the outer protruding cover 11, and the end of the embedded rod 13 is inserted into the magnetic coupling seat 12 and is rotationally clamped with the magnetic coupling seat 12;

[0050] During operation, in order to improve the applicable range of the equipment, another model is designed. In this model, the embedded rod 13 passes through the outer protruding cover 11 and the magnetic coupling seat 12, and the separation cover 3 is maintained outside the outer protruding cover 11 without external support. The transmission still relies on magnetic attraction transmission. Since the embedded rod 13 is located in the middle position, it is also difficult for foreign objects from the outside to invade it.

[0051] During operation, multiple slidable isolation plates 2 are arranged on the outer side of the sealed housing 1. During the operation of the waterproof motor, the power assembly drives the multiple isolation plates 2 to reciprocate on the outer side of the sealed housing 1. The slider 14 is clamped in the moving groove 9, enabling the isolation plate 2 to only slide horizontally. Since the isolation plate 2 completely covers the outer side of the sealed housing 1, the reciprocating isolation plate 2 prevents the attachments in the water from staying on the outer side of the isolation plate 2. Moreover, the isolation plate 2 fits perfectly with the sealed housing 1, allowing the heat of the sealed housing 1 to exchange and dissipate heat with the external water flow through the isolation plate 2. With this setting, the waterproof motor can be stored underwater for a long time without a large amount of attachments adhering to the surface of the sealed housing 1, enabling the waterproof motor to normally exchange heat with water. At the same time, the reduction of attachments can also reduce the erosion of the outer side of the waterproof motor by the attachments;

[0052] In order for the waterproof motor to work underwater for a long time and prevent external water sources from entering the interior and causing damage, generally, waterproof structures such as sealing rings need to be installed at the connection between the rotor 10 and the sealed housing 1. However, it is difficult for the waterproof structure to maintain sealing after long-term use, and the sealing structure will rub against the rotor 10, resulting in power consumption. With the setting of the magnetic coupling seat 12, when the rotor 10 rotates, it drives the magnetic coupling seat 12 to rotate. Under magnetic adsorption, it drives the magnet disk and the separation cover 3 to rotate. The external structure that needs to be driven is connected to the transmission head 4. It should be noted that the external transmission structure needs to be fixed additionally. For example, if an external propeller is used, the outer side of the propeller needs to be rotationally clamped, so that the separation cover 3 can be restricted outside the protruding cover 11 for non-contact transmission. Under this design, the sealed housing 1 and the protruding cover 11 seal the motor body as a whole inside and do not come into contact with external water sources at all. This not only avoids the invasion of external water sources but also greatly improves the safety of the equipment when used underwater;

[0053] The arrangement of the metal frustum and the magnetic blocks enables a large adsorption surface between the magnetic coupling seat 12 and the separation cover 3, which can transfer the magnetic ability to a greater extent. The staggered arrangement of the magnetic poles, compared with the design where all the magnetic blocks have the same magnetic poles, each individual magnetic block has an independent adsorption effect, preventing the magnetic coupling seat 12 from easily moving relative to the magnet disk, thus enabling better transmission of rotational kinetic energy;

[0054] As the separation cover 3 rotates, the ends of the two repulsion seats 6 will continuously approach the ends of each isolation plate 2 during the rotation process. Under the action of magnetic repulsion, the isolation plate 2 will be pushed away. During the repulsion process, the two do not come into contact. When the repulsion seat 6 moves away, under the action of the spring telescopic rod 19, the slider 14 and the isolation plate 2 are pulled back, thus enabling the isolation plate 2 to return to its original position. With this setting, the rotation of the separation cover 3 is utilized to achieve the repeated sliding process of the multiple isolation plates 2, eliminating the need for additional driving electrical appliances, thereby reducing the manufacturing cost and the operation difficulty;

[0055] The entire sealed housing 1 is supported to a suspended state by the bending arm 8 and the support seat 5, so that the isolation plate 2 can work normally, and the wide support seat 5 can stably support the entire sealed housing 1;

[0056] In order to make the movement of the isolation plate 2 controllable, the multiple steel cables 7 can be pulled by shortening the hydraulic rod, thereby pulling the isolation plate 2 away from the separation cover 3, so that the repelling seat 6 will not push the isolation plate 2 to move when passing through the isolation plate 2, and the waterproof motor can operate normally without losing energy due to pushing the isolation plate 2. When it is necessary to clean the surface of the isolation plate 2, the hydraulic rod is extended to release the steel cables 7, and the isolation plate 2 is returned to its position under the action of the spring telescopic rod 19, so that the repelling seat 6 can drive the isolation plate 2;

[0057] In order to increase the ability of the isolation plate 2 to clean the outer surface, by changing the top surface of the isolation plate 2 to an elastic metal plate 17, during the movement of the isolation plate 2, the bottom surface of the metal plate 17 is pulled by the pulling component. Since the metal plate 17 has toughness and elasticity, it will be concave downward during the pulling process. After the pulling is completed, it will rebound under the action of its own elasticity, which can generate vibration on the surface of the metal plate 17, and the surface attachments can be removed more effectively, thereby ensuring the heat dissipation effect of the motor, thereby improving the service life;

[0058] During the translation of the isolation plate 2 and the slider 14, the second steel cable 16 is pulled, thereby pulling the metal plate 17 downward, causing the metal plate 17 to be concave. When the isolation plate 2 is returned to its original position, the metal plate 17 will rebound and vibrate under its own elasticity, thereby completing the shaking cleaning work. This arrangement realizes the use of the sliding action of the isolation plate 2 to drive the pulling of the second steel cable 16, without the need for additional electrical appliances.

[0059] By combining multiple steel cables 16 into a forked steel cable, only the ends of two forked steel cables need to pass through the slider 14 to complete the transmission pulling effect. The setting of the inner slide groove 20 prevents the bottom of the forked steel cable from affecting the sliding of the slider 14. The setting of the limit ring 15 can limit the moving track of the forked steel cable to prevent it from running around.

[0060] In order to improve the applicability of the equipment, another model is designed. In this model, the embedded rod 13 passes through the protruding cover 11 and the magnetic coupling seat 12, so that the separation cover 3 is maintained on the outside of the protruding cover 11. No external support is required, and the transmission still relies on magnetic transmission. Since the embedded rod 13 is located in the middle position, it is difficult for foreign objects to invade it.

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.

The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
