TECHNICAL FIELD

[0002] The permanent magnet generator is a device for converting mechanical energy into electrical energy through electromagnetic induction principle by using a permanent magnet to provide an excitation magnetic field.

[0003] During the operation of the permanent magnet generator, heat is generated due to electromagnetic loss and mechanical friction, and when the heat accumulates to a certain degree, the permanent magnet will demagnetize or the insulation will age. Therefore, in order to maintain the safe and efficient operation of the permanent magnet generator, the staff generally equips the permanent magnet generator with a forced cooling device.

[0004] The existing forced cooling device can efficiently and continuously cool the running permanent magnet generator, avoid the influence of water in the air on the permanent magnet generator, and ensure the safe and efficient operation of the permanent magnet generator. However, the following problems exist:

[0005] During the operation of the forced cooling device, the water carried in the air is adsorbed and treated by the adsorbent particles.

[0041] In this embodiment, when the generator body 3 needs to be run, the temperature sensor 106 and the humidity sensor 105 are started by the controller 119 at this time. The temperature sensor 106 and the humidity sensor 105 started at this time will detect the humidity inside the space composed of the heat insulation shell 101, the first top plate 102 and the second top plate 103 and the temperature of the surface of the generator body 3 at all times, and will transmit the temperature data and the humidity data detected each time to the controller 119 in the form of an electrical signal. After receiving the temperature data and the humidity data, the controller 119 will compare each humidity data and each temperature data with the humidity threshold value and the temperature threshold value respectively. When the humidity data is higher than the humidity threshold value set by the controller 119 in advance, the controller 119 will start one of the electric valves 111 (corresponding to the processing box 108) and the fan body 123 at this time.

[0043] When the inside of the processing box 108 needs to be filled with adsorbent particles, the controller 119 is first used to start the electric cylinder 205, which drives the trapezoidal block 206 to move in the direction of the baffle 215 under the cooperation of all the rectangular rings 204, one of the discharge boxes 202 and all the support frames 201. The moving trapezoidal block 206 drives the two round rods 213 to move vertically upward under the cooperation of all the second perforated blocks 212.

When the side of the baffle 215 away from the single-opening pipe 217 is at the same level as the inner wall of the discharge pipe 214, the controller 119 temporarily stops the electric cylinder 205. The used adsorbent particles in the inside of the processing box 108 flow out of the discharge port and enter the inside of the discharge pipe 214. The used adsorbent particles near the processing box 108 in the inside of the feeding pipe 207 also enter the discharge pipe 214 through the processing box 108 and then enter another discharge box 202.When the outlet of the discharge pipe 214 is filled with each adsorbent particle, the baffle 215 is reset to the original position at this time by the cooperation of the controller 119, the electric cylinder 205 and the previous linkage components, and then the above-mentioned rapid feeding steps are repeated to fill the inside of the processing box 108 with new adsorbent particles, that is, the rapid replacement operation of the adsorbent particles is realized, and the forced cooling device can be quickly put into use.

[0044] The effect and working principle of the whole mechanism are as follows:

[0045] In the preparation stage, the humidity sensor 105, the temperature sensor 106 (infrared type), all the electric valves 111, the radiator 120 (fan type), the fan body 123, the electric cylinder 205 and the controller 119 are connected according to the electrical safety connection criteria and requirements, then the controller 119 is connected to the mains or power supply device through the prepared cable, then the main shaft of the generator body 3 is connected to the output shaft of the prime mover (energy input device), at the same time, the generator body 3 is connected to the transformer, the transformer is connected to the power grid, then the controller 119 is turned on, the initial interface is entered, then various parameters such as the temperature threshold, the humidity threshold and the rotating speed of the fan body 123 are set, then the box cover 203 placed on the top of one of the discharge boxes 202 is removed, then an appropriate amount of adsorbent particles (3A molecular sieve particles) is injected into the inside of the discharge box 202, and finally the box cover 203 is installed back to the original position.

[0046] When the inside of the processing box 108 needs to be filled with adsorbent particles, the controller 119 first starts the electric cylinder 205, which drives the trapezoidal block 206 to move towards the baffle 215 under the cooperation of all the rectangular rings 204, one of the discharge boxes 202 and all the support frames 201. Then the moving trapezoidal block 206 drives the two round head rods 213 to move vertically upwards under the cooperation of all the second perforated blocks 212. Next, the two moving round head rods 213 drive the connecting frame 210 to move vertically upwards under the cooperation of all the first perforated blocks 209. After that, the moving connecting frame 210 also drives the stop block 208 to move, and at the same time, the moving connecting frame 210 also drives all the reset springs 211 to be stretched under the cooperation of all the first perforated blocks 209. At the same time, the moving trapezoidal block 206 also drives all the T-shaped rods 218 to move, and each moving T-shaped rod 218 drives the corresponding spring body 219 to be compressed under the cooperation of the corresponding mounting seat 216, the corresponding single-opening pipe 217, the discharge pipe 214 and the baffle 215 (at this time, each T-shaped rod 218 moves towards the inside of the corresponding single-opening pipe 217 while the corresponding spring body 219 is compressed). When the bottom slope of the stop block 208 is at the same level as the top slope of the inner wall of the feed pipe 207, the controller 119 stops the electric cylinder 205, and the adsorbent particles in one of the discharge boxes 202 flow out of the discharge port, flow into the inside of the processing box 108 through the feed pipe 207. When the inside of the processing box 108 is filled with adsorbent particles, the controller 119, the electric cylinder 205, the rebound force of each spring body 219, the rebound force of each reset spring 211 and the cooperation of the previous linkage components are used to reset each T-shaped rod 218 and the stop block 208 to their original positions.

[0047] compared with the humidity threshold value and the temperature threshold value respectively, when the humidity data is higher than the humidity threshold value set by the controller 119 in advance, at this time the controller 119 will start one of the electric valves 111 (corresponding to the processing box 108) and the fan body 123, at this time the air outlet end of the started fan body 123 will blow air into the inside of the heat preservation shell 101 through the round hole reserved on the other side plate surface of the heat preservation shell 101, and the air entering the inside of the heat preservation shell 101 will be transported into the inside of each manifold 118 under the cooperation of the first top plate 102 and the second top plate 103, and then into the inside of the corresponding connector 116, and then converged into the inside of the second multi-way pipe 115, and then transported into the inside of the flow divider 112, and then enter the inside of the processing box 108 through the opened one of the electric valves 111, and at the same time part of the air also enters the space of the feed pipe 207 close to the processing box 108 (separated by the block 208), when the air contacts the adsorbent particles in the inside of the processing box 108 and the adsorbent particles in the space of the feed pipe 207 close to the processing box 108, at this time the moisture carried by the air will be adsorbed and removed by the adsorbent particles, and then the dried air will enter the inside of the corresponding one-way valve 113, and then transported into the inside of the first multi-way pipe 114, and then transported into the inside pipe of the radiator 120, and then transported back to the inside of the fan body 123 through the fan cover 122 for new circulation, when the humidity data received by the controller 119 is lower than the humidity threshold value set by the controller 119 in advance, at this time the controller 119 will close the fan body 123 and close one of the electric valves 111, when the generator body 3 generates electricity and the temperature data received by the controller 119 is higher than the temperature threshold value set by the controller 119 in advance, at this time the controller 119 will start the fan body 123, the other electric valve 111 (corresponding to the L-shaped pipe 125) and the radiator 120, at this time the air entering the inside of the flow divider 112 (at this time the air carries heat, and the heat is generated when the generator body 3 runs) will enter the inside of the L-shaped pipe 125 through the opened other electric valve 111, and then enter the inside of the corresponding one-way valve 113, and then pass through the first multi-way pipe 114 and enter the inside pipe of the radiator 120, when the air carrying heat enters the inside of the radiator 120, at this time the radiator 120 will lower the temperature of the entering air,The air cooled down will return to the space inside again, and so on, so as to forcibly cool the generator body 3. When the temperature data received by the controller 119 is lower than the temperature threshold set by the controller 119 in advance, the controller 119 will turn off the fan body 123, the other electric valve 111 and the radiator 120.

[0048] When the adsorbent particles inside the processing box 108 and the space near the feeding pipe 207 close to the processing box 108 need to be replaced, the controller 119 is used to start the electric cylinder 205 first, so that the electric cylinder 205 drives the trapezoidal block 206 to move (away from the baffle 215), at this time, the trapezoidal block 206 drives all the T-shaped rods 218 to move, and each T-shaped rod 218 drives the baffle 215 to move together under the cooperation of the corresponding spring body 219, the corresponding mounting seat 216 and the corresponding single-opening pipe 217, and the bottom end of each round head rod 213 also slides on the top plane of the trapezoidal block 206. When the side of the baffle 215 away from the single-opening pipe 217 is at the same horizontal plane as the inner wall of the discharging pipe 214, the controller 119 is used to pause the electric cylinder 205, at this time, the used adsorbent particles inside the processing box 108 flow away from the discharge port position and enter the inside of the discharging pipe 214, and the used adsorbent particles near the processing box 108 inside the space of the feeding pipe 207 also pass through the processing box 108 and enter the inside of the discharging pipe 214, and then enter another discharging box 202 for storage. When each adsorbent particle flows out of the outlet of the discharging pipe 214, the controller 119, the electric cylinder 205 and the previous linkage components are used to reset the baffle 215 to the original position, and then the steps of the above rapid feeding stage are repeated to fill the processing box 108 with new adsorbent particles.

[0049] The heat insulation shell 101 is composed of two heat insulation side plates, a heat insulation front plate, a heat insulation back plate, a heat insulation bottom plate, a support block, a strip-shaped angle steel and a reinforcing plate. The strip-shaped angle steel is used to fix the two heat insulation side plates, the heat insulation front plate, the heat insulation back plate and the heat insulation bottom plate together, and the reinforcing plate is used to enhance the stability of the two heat insulation side plates, the heat insulation front plate and the heat insulation bottom plate after being fixed together.

[0050] The gas inlet outlet of the processing box 108 and the gas outlet outlet of the processing box 108 are fixed with porous isolation sheets in advance, which are used to prevent the adsorbent particles from entering the gas inlet and outlet of the processing box 108.

[0051] Among them, the heat insulation shell 101, the humidity sensor 105, the temperature sensor 106, the adsorption layer 109 (composed of a plurality of adsorbent particles), the electric valve 111, the connector 116, the controller 119 (PLC controller), the radiator 120, the fan body 123, the electric cylinder 205 and the generator body 3 are all prior art, and their models can be selected according to actual conditions, and will not be explained too much here.
