Description

Technical Field

[0001] The present invention relates to the technical field of generators, in particular to a permanent magnet generator with a shell heat dissipation mechanism. Background Art

[0002] A permanent magnet generator is a generator that uses permanent magnets to generate a magnetic field. Due to its advantages such as high efficiency, energy saving, low carbon, high power and small size, it is widely used in home appliances, medical equipment, automobiles, aviation and other fields.

[0043] The second movable ring 7 is installed on the cooperating rotating shaft 6, and the second movable ring 7 is symmetrically fixed with connecting strips 71 on both sides of the second movable ring 7.

The movable plug rod 72 is inserted in the movable socket 67, and the upper end of the movable plug rod 72 is hinged with a connecting hinge 73. The upper end of the connecting hinge 73 is hinged with a bearing connecting block 74. A bearing connecting rod 75 is fixed on the bearing connecting block 74. The bearing connecting rod 75 is inserted in the movable through hole 66. A locking card plate 76 is fixed on the bearing connecting rod 75, and a first spring 77 is sleeved on the bearing connecting rod 75. The two ends of the first spring 77 are respectively fixed on the bearing vertical plate 65 and the locking card plate 76, and the locking card plate 76 is overlapped on the inclined plane driving platform 43 when realizing the fixed connection between the first rotating shaft 4 and the cooperating rotating shaft 6.

[0046] When the motor is working, the water pump 24 also works synchronously to pump water from the water tank 21 into the water-cooling circulation pipe 3 through the condenser 25. As the cooling water flows, the heat inside the motor can be absorbed and taken out. At the same time, the first rotating blade 41 will be driven to rotate under the action of the water flow. As the first rotating blade 41 rotates, the first rotating shaft 4 will also be driven to rotate, and then the matching rotating shaft 6 will be driven to rotate, so that the heat dissipation fan blade 61 can be rotated, which can achieve synchronous air cooling and heat dissipation. In addition, the second rotating blade 831 will be driven to rotate under the action of the water flow, and the rotation of the second rotating blade 831 will also drive the push The movable contact plate 81 rotates, and the push contact plate 81 contacts the matching drive plate 93 on the side during the rotation. In this way, the push contact plate 81 pushes the matching drive plate 93 to move, so that the movable cover plate 9 no longer covers the heat dissipation hole 28, so that the heat dissipation hole 28 is opened, which is convenient for the heat dissipation inside the motor. When the motor is not dissipating heat, the movable cover plate 9 covers the heat dissipation hole 28, which can effectively prevent external dust from entering the interior of the motor housing 2. In this way, under the joint heat dissipation effect of air cooling and water cooling, the interior of the motor can be well cooled to ensure that the heat dissipation requirements can be met. In addition, When installing the water-cooling circulation pipe 3 and the matching rotating shaft 6, the connecting pipe 31 on the water-cooling circulation pipe 3 is inserted into the connecting pipe groove 23 to realize the sealed connection between the water-cooling circulation pipe 3 and the return pipe 22 and the outlet pipe 26. Then, the matching rotating shaft 6 is installed, that is, the cross block 63 on the matching rotating shaft 6 is inserted into the cross connecting groove 44, and the matching rotating shaft 6 is pushed upward. In the process of pushing upward, the locking card 76 will contact the inclined drive platform 43, so that the locking card 76 will be pushed to move under the action of the inclined drive platform 43, and at the same time, the second movable ring 7 will be driven upward relative to the matching rotating shaft 6 under the action of the connecting hinge 73. Move until the locking card 76 passes over the inclined drive platform 43, and then it is reset, so that the locking card 76 overlaps the upper end of the inclined drive platform 43, realizing a fixed connection between the first rotating shaft 4 and the mating rotating shaft 6. When the mating rotating shaft 6 moves upward, the contact wheel 69 contacts the first movable ring 5, which will push the first movable ring 5 to move upward. As the first movable ring 5 moves upward, the supporting positioning plate 54 will be pushed to move under the action of the mating connecting rod 53, thereby making the plug-in fixing plate 55 on the supporting positioning plate 54 plug into the corresponding positioning plug-in cavity 29, realizing multi-point fixation of the water-cooling circulation pipe 3, which is very convenient and fast.
