Description

Technical Field

[0001] The utility model relates to the technical field of permanent magnet generators, in particular to a low-loss marine permanent magnet generator. Background Art

[0002] A permanent magnet generator is a power generation device that converts mechanical energy converted from heat energy into electrical energy. It is usually made of strong magnetic materials such as iron boron magnets or neodymium iron boron magnets, which can maintain their magnetic field when no current is added. The magnets are fixed in the rotor of the generator and generate a magnetic field by rotating at high speed. Among them, when the permanent magnet generator is used in ships, the ship may operate under different environmental conditions, including high temperature, high humidity, etc. However, the existing permanent magnet generator is directly exposed to the outside, and while ensuring heat dissipation, it only relies on its own shell sealing structure to resist the entry of external moisture, which is not effective and affects the normal operation of the generator. There are certain shortcomings. For this reason, we propose a low-loss marine permanent magnet generator. Utility Model Content

[0003] The utility model aims to solve the problems existing in the prior art or related technologies.

[0004] To this end, the technical solution adopted by the utility model is: a low-loss marine permanent magnet generator, including a supporting assembly, an air inlet assembly, an air outlet assembly and a sealing assembly, the supporting assembly including a fixed plate, a generator body arranged on the top of the fixed plate, a surrounding plate arranged on the top of the fixed plate, a groove opened on the top of the fixed plate and a first desiccant placed in the groove, the air inlet assembly including an air inlet pipe arranged on the left side of the surrounding plate, a filter arranged in the air inlet pipe, a second desiccant placed in the air inlet pipe, a first fan arranged in the air inlet pipe, a feed pipe arranged at the top of the air inlet pipe and a discharge pipe arranged at the bottom of the air inlet pipe, the air outlet assembly including an air outlet pipe arranged on the right side of the surrounding plate and a second fan arranged in the air outlet pipe, and the sealing assembly including an adjustment frame inserted into the outside of the surrounding plate and a top cover hinged to the top of the adjustment frame.

[0005] Preferably, a fixing rod is provided on the outer side of the enclosure, and an adjustment hole is opened on the fixing rod.

[0006] Preferably, the feed pipe and the discharge pipe are both threadedly connected with sealing covers, and the feed pipe and the discharge pipe have the same diameter.

[0007] Preferably, it further comprises a left rubber cover, a first rubber tube is arranged on the right side of the left rubber cover, and the left rubber cover is fixedly connected to the air inlet pipe through the first rubber tube.

[0008] Preferably, it further comprises a right rubber cover, a second rubber tube is arranged on the left side of the right rubber cover, and the right rubber cover is fixedly connected to the air outlet pipe through the second rubber tube.

[0009] Preferably, it further comprises an adjusting member, wherein the adjusting member comprises a stud arranged outside the adjusting frame and a nut threadedly connected to the stud.

[0010] By adopting the above technical scheme, the beneficial effects achieved by the utility model are as follows: the utility model realizes a dry environment without affecting the heat dissipation by arranging the support assembly, the air inlet assembly, the air outlet assembly, the sealing assembly and the adjusting member, effectively preventing moisture from entering the generator, and conveniently replacing the desiccant through the feed pipe and the discharge pipe for use. When in use, the user can control the operation of the first fan and the second fan. The operation of the first fan and the second fan can speed up the air exchange speed inside and outside the enclosure, that is, quickly dissipate heat. When the air is inlet, the second desiccant in the filter can absorb the incoming moisture to prevent moisture from entering the enclosure. Then, the first desiccant can absorb the moisture in the enclosure to ensure that the generator is in a dry environment and prevent moisture from entering the generator. At the same time, the sealing covers of the feed pipe and the discharge pipe can be rotated. After detachment, the second desiccant can be discharged through the discharge pipe, and a new second desiccant can be added to the air inlet pipe through the feed pipe for replacement. Then the nut can be loosened, and the adjustment frame can be moved up and down after loosening. The space inside the enclosure can be adjusted by adjusting the height of the adjustment frame to avoid the enclosure limiting the circulation of air around the generator due to the small internal space, making it difficult for the heat generated by the generator to be effectively dissipated, resulting in poor heat dissipation effect.

A fixed rod 104 is arranged on the outside of the surrounding plate 103, and an adjustment hole is opened on the fixed rod 104. The fixed rod 104 can cooperate with the adjustment member 700 to adjust the height of the sealing assembly 600.

[0027] Specifically, the air inlet assembly 200 includes an air inlet pipe 201 arranged on the left side of the enclosure 103, a filter 202 arranged in the air inlet pipe 201, a second desiccant 203 placed in the air inlet pipe 201, a first fan 204 arranged in the air inlet pipe 201, a feed pipe 205 arranged at the top of the air inlet pipe 201 and a discharge pipe 206 arranged at the bottom of the air inlet pipe 201. The filter 202 can support the second desiccant 203 so as to place the second desiccant 203, and the second desiccant 203 can absorb the incoming moisture to prevent moisture from entering the enclosure 103. The feed pipe 205 and the discharge pipe 206 are both threadedly connected with a sealing cover 207. The feed pipe 205 and the discharge pipe 206 have the same pipe diameter. The sealing cover 207 is rotatable. After being detached, the second desiccant 203 can be discharged through the discharge pipe 206, and a new second desiccant 203 can be added to the air inlet pipe 201 through the feed pipe 205 for replacement.

[0028] Specifically, the air outlet assembly 300 includes an air outlet pipe 301 disposed on the right side of the enclosure 103 and a second fan 302 disposed in the air outlet pipe 301. The air in the enclosure 103 can be quickly discharged through the second fan 302 to dissipate heat.

[0033] The working principle and use process of the utility model are as follows: when in use, the user can control the first fan 204 and the second fan 302 to operate. The operating first fan 204 and the second fan 302 can speed up the air exchange speed between the inside and outside of the enclosure 103, so as to dissipate heat quickly. When the air enters, the second desiccant 203 in the filter screen 202 can absorb the moisture entering, so as to prevent the moisture from entering the enclosure 103. Then, the first desiccant 106 can absorb the moisture in the enclosure 103, so as to ensure that the generator can be in a dry environment, so as to prevent the moisture from entering the generator. When the desiccant needs to be replaced, the sealing cover 207 of the feed pipe 205 and the discharge pipe 206 can be rotated, and the second desiccant can be discharged through the discharge pipe 206 after being detached. Desiccant 203, and new second desiccant 203 can be added to the air inlet pipe 201 through the feeding pipe 205 for replacement. When the space in the enclosure 103 is too small, the nut 702 can be loosened. After the nut 702 is loosened, the adjustment frame 601 can be moved up and down. The space inside the enclosure 103 can be adjusted by adjusting the height of the adjustment frame 601 to avoid the enclosure 103 limiting the circulation of air around the generator due to the small internal space, making it difficult for the heat generated by the generator to be effectively dissipated, resulting in poor heat dissipation. When storing, the left rubber cover 400 can be inserted into the air inlet pipe 201, and then the right rubber cover 500 can be inserted into the air outlet pipe 301 to seal it for storing the generator.
