Description

Technical Field

[0001] The utility model relates to a waterproof permanent magnet motor, in particular to a marine waterproof permanent magnet motor, belonging to the technical field of motors. Background Art

[0002] Permanent magnet motors use permanent magnets to provide excitation, which makes the motor structure simpler, reduces processing and assembly costs, and eliminates slip rings and brushes that are prone to problems, thereby improving the reliability of motor operation. Because no excitation current is required and there is no excitation loss, the efficiency and power density of the motor are improved. However, most motors are not waterproof. When encountering an environment with moisture, the motor cannot be waterproof, which will cause some of its functions to be reduced. In severe cases, the motor will be damaged, resulting in the inability to complete the work and increasing maintenance costs.

[0003] However, when the marine permanent magnet motor is operating normally, the turbulence of the hull may cause moisture to enter the cabin, and then may enter the permanent magnet motor. Or on some small boats, rain may cause moisture to enter the motor from the tail end of the permanent magnet motor, causing damage to the permanent magnet motor and failure to work properly. Utility Model Content

[0004] The purpose of the utility model is to provide a marine waterproof permanent magnet motor in order to solve the above-mentioned problem. When the hull enters the water or it rains, it is only necessary to rotate the shaft 90 degrees so that the second ventilation hole on the protective plate is staggered with the first ventilation hole on the ventilation plate, thereby preventing the entry of moisture.

[0005] The utility model achieves the above-mentioned purpose through the following technical scheme: a marine waterproof permanent magnet motor, comprising a permanent magnet motor, a protective structure installed at the bottom end of the permanent magnet motor, the protective structure comprising a ventilation plate, the bottom end of the permanent magnet motor is fixedly connected to the ventilation plate, the side end of the ventilation plate is provided with a plurality of first ventilation holes, a rotating shaft is rotatably connected inside the ventilation plate, the side end of the rotating shaft is fixedly connected to a protective plate, the protective plate is rotatably connected to the ventilation plate, and the side end of the protective plate is provided with a plurality of second ventilation holes.

[0006] Preferably, a button block is fixedly connected to the side end of the rotating shaft, a slider is slidably connected inside the rotating shaft, the slider is fixedly connected to the side end of the button block, a first spring is fixedly connected between the slider and the rotating shaft, a connecting block is fixedly connected to the side end of the ventilation plate, the connecting block is rotatably connected to the rotating shaft, the button block contacts the connecting block, a plurality of clamping blocks are fixedly connected to the side end of the button block, and the clamping blocks are plugged into the connecting blocks.

[0007] Preferably, the cross-section of the bottom end of the slider is in the shape of a rectangular parallelepiped, and the cross-section of the top end of the block is in the shape of an arc.

[0008] Preferably, a sun protection structure is detachably installed on the top of the permanent magnet motor, and the sun protection structure includes a sun protection plate. The top of the permanent magnet motor is detachably connected to the sun protection plate, and the bottom of the sun protection plate is fixedly connected to a resistance block, which resists the top of the permanent magnet motor.

[0009] Preferably, a limiting block is fixedly connected to the bottom end of the sun visor, and the limiting block abuts against the side end of the permanent magnet motor.

Through the resistance between the resistance block 302 and the top of the permanent magnet motor 1, the sun protection plate 301 can be stably placed above the permanent magnet motor 1 to protect the permanent magnet motor 1.

[0027] As a technical optimization solution of the utility model, the bottom end of the sun shading plate 301 is fixedly connected to a limiting block 303, and the limiting block 303 abuts against the side end of the permanent magnet motor 1. Through the abutment between the limiting block 303 and the permanent magnet motor 1, the sun shading plate 301 is better fixed on the permanent magnet motor 1.

[0028] As a technical optimization solution of the utility model, a groove 304 is provided at the side end of the permanent magnet motor 1, and a protrusion block 305 is slidably connected in the limit block 303. The protrusion block 305 is engaged with the groove 304.

[0031] When the utility model is in use, when it is necessary to waterproof the permanent magnet motor 1, first pull the button block 206, the button block 206 drives the block 210 to move, so that the block 210 is separated from the connecting block 209, and at the same time the button block 206 drives the slider 207 installed at the side end to move, the bottom end cross section of the slider 207 is in the shape of a rectangular parallelepiped, the slider 207 generates an extrusion force on the first spring 208, when the block 210 is completely separated from the connecting block 209, rotate the button block 206, at this time, due to the effect of the rectangular cross section of the slider 207, it will drive the shaft 203 to rotate together, and the shaft 203 drives the protective plate 204 installed at the side end to rotate together When the button 206 is rotated by ninety degrees, the second ventilation hole 205 provided on the protection plate 204 is completely staggered with the first ventilation hole 202 provided on the ventilation plate 201, so that moisture cannot enter the permanent magnet motor 1, thereby protecting the permanent magnet motor 1. When it is not necessary to waterproof the permanent magnet motor 1, the button 206 is pulled to separate the clamping block 210 from the connecting block 209, and the button 206 is rotated by ninety degrees to make the first ventilation hole 202 coincide with the second ventilation hole 205, so as to dissipate heat for the permanent magnet motor 1. Since some permanent magnet motors 1 are exposed on the hull, the permanent magnet motor 1 will be exposed to the hull.

Through the protrusion block 302, the sunscreen 301 can be fixed. 05 is engaged with the groove 304 at the side end of the permanent magnet motor 1, which can further fix the sunscreen 301. A second spring 306 is installed in the limit block 303. The second spring 306 can squeeze the protrusion block 305 to make it more tightly engaged with the groove 304. A stopper 307 is installed on the top of the protrusion block 305, so that when the second spring 306 squeezes the protrusion block 305, the protrusion block 305 is prevented from sliding out of the limit block 303, and it is also more conducive to the installation and disassembly of the sunscreen 301, thereby protecting the permanent magnet motor 1, reducing the sunlight exposure to the permanent magnet motor 1, and reducing the temperature of the surface of the permanent magnet motor 1.
