Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of generator cooling, in particular to an auxiliary cooling device for shaft generator. BACKGROUND

[0002] The shaft generator is a key equipment for generating power by using the residual power of the main engine of the ship, and is of great significance to improve the energy efficiency of the ship. A large amount of heat is generated during the operation of the shaft generator, and an effective cooling system is needed to ensure its normal operation. At present, the cooling methods of the shaft generator mainly include two types. One is to simply rely on the fan at the tail end of the shaft generator for forced air cooling. This method has a simple structure, but when the temperature of the ship engine room environment is high, the temperature of the heat dissipation medium (air) itself is close to or exceeds the cooling target temperature, resulting in a small heat exchange temperature difference and a sharp decrease in heat dissipation efficiency, which is difficult to meet the heat dissipation demand of the generator. In order to improve the heat dissipation efficiency, auxiliary cooling devices are proposed, such as a scheme combining a fan and a cooling pipeline. The basic principle is to use the cold water flowing through the cooling pipeline to pre-cool the air, and then blow the cooled air to the generator to increase the heat exchange temperature difference.

[0003] However, the prior art has obvious defects:

[0004] Firstly, due to the simple structure design of the cooling pipeline (such as using straight pipes or simple coils), the air flow path is short and the contact time with the cooling pipe is limited, resulting in insufficient heat exchange time between the air and the coolant water, and the air cannot be fully cooled, which limits the improvement of the final heat dissipation effect.

[0005] Secondly, most existing devices do not have an effective filtering mechanism before the cooling water enters the pipeline. The impurities, scale and other foreign matters contained in the cooling water of the ship are easy to accumulate on the inner wall of the pipeline. The formation of scale can significantly increase the thermal resistance and seriously reduce the heat exchange efficiency. Long-term operation may even cause pipeline blockage, affecting the normal operation of the cooling system and increasing the maintenance cost. SUMMARY

[0041] Specifically, as Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 8 、 Figure 9 and Figure 11As shown, the connecting frame 401 is provided with an on-off structure 5, the on-off structure 5 comprises a flow guide base 501 and a flow channel 502, the connecting frame 401 is fixedly connected with the flow guide base 501, the inside of the flow guide base 501 is provided with two flow channels 502, one of the flow channels 502 is in communication with one end of the cold water pipe 402, the flow guide base 501 is threadedly connected with a screw rod 504, one end of the screw rod 504 is rotatably connected with a moving plate 505, the moving plate 505 is fixedly connected with two valve plates 506, the valve plates 506 are slidably connected with the flow guide base 501, the flow guide base 501 is fixedly connected with a connecting cylinder 507, the connecting cylinder 507 is in communication with the two flow channels 502, the screw rod 504 is fixedly connected with a rotating rod 503, the rotating rod 503 is perpendicular to the screw rod 504, the connecting cylinder 507 is provided with a filtering structure 7, the filtering structure 7 comprises a blocking ring 701 and a support frame 702, the inside of the connecting cylinder 507 is fixedly connected with the blocking ring 701, the support frame 702 abuts against the blocking ring 701, the top end of the support frame 702 abuts against a sealing plug 704, the sealing plug 704 is threadedly connected with the connecting cylinder 507, the support frame 702 is fixedly connected with a filter screen 703, the connecting cylinder 507 is provided with a blocking structure 6, the blocking structure 6 comprises a connecting seat 601 and a blocking rod 602, the outside of the connecting cylinder 507 is fixedly connected with the connecting seat 601, the connecting seat 601 is rotatably connected with the blocking rod 602, the blocking rod 602 is fixedly connected with a second guide shaft 603, the moving plate 505 is fixedly connected with a connecting plate 605, the connecting plate 605 is provided with a second guide groove 604, the second guide shaft 603 extends into the second guide groove 604 and is slidably connected with the connecting plate 605, the blocking rod 602 abuts against the sealing plug 704, the second guide groove 604 is provided with two sections, the first section is in the same direction as the moving direction of the moving plate 505, the second section is obliquely arranged towards the connecting cylinder 507, that is, the cooling water conveying pipeline can be connected with the flow guide base 501, during the circulation of the cooling water, the cooling water enters into one of the flow channels 502 from the cooling water conveying pipeline, then flows into the inside of the connecting cylinder 507 from the flow channel 502, then enters into the other flow channel 502 from the inside of the connecting cylinder 507, and finally enters into the inside of the cold water pipe 402, before the cooling water enters into the other flow channel 502, the particles in the cooling water can be filtered by the filter screen 703, so that the particles in the cooling water do not form scale in the cold water pipe 402 to reduce the heat exchange effect of the cold water pipe 402, and when the filter screen 703 needs to be disassembled and cleaned, the screw rod 504 can be rotated by holding the rotating rod 503, the rotation of the screw rod 504 drives the moving plate 505 to move, the movement of the moving plate 505 drives the two valve plates 506 to move, and the movement of the moving plate 505 drives the connecting plate 605 to move,Thus, the second guide shaft 603 moves inside the second guide groove 604, and when the second guide shaft 603 moves inside the first section of the second guide groove 604, the blocking rod 602 does not rotate, and when the valve plate 506 is about to seal the flow channel 502, the second guide shaft 603 moves inside the second section of the second guide groove 604, at which time the blocking rod 602 rotates away from the sealing plug 704, and when the valve plate 506 completely seals the flow channel 502, the blocking rod 602 does not block the sealing plug 704, so that when the sealing plug 704 is removed, the situation that cooling water is sprayed due to the fact that the valve plate 506 does not completely seal the flow channel 502 can be avoided, thereby effectively improving the safety of operation, and then the sealing plug 704 can be twisted off from the connecting cylinder 507, and then the supporting frame 702 is taken out from the inside of the connecting cylinder 507, and the filter screen 703 is taken out together with the supporting frame 702, and after the filter screen 703 is taken out, the dirt attached to the surface of the filter screen 703 can be cleaned, thereby effectively ensuring the filtering effect.

[0042] In use, the cooling water conveying pipeline can be connected with the flow guide base 501, and in the process of circulating flow of the cooling water, the cooling water enters the inside of one of the flow channels 502 from the cooling water conveying pipeline, then flows into the inside of the connecting cylinder 507 from the inside of one of the flow channels 502, then enters the inside of the other flow channel 502 from the inside of the connecting cylinder 507, and finally enters the inside of the cold water pipe 402. Before the cooling water enters the inside of the other flow channel 502, the particulate impurities in the cooling water can be filtered through the filter screen 703, so that the particulate impurities are prevented from entering the inside of the cold water pipe 402 to form scale and reduce the heat exchange effect of the cold water pipe 402. When it is necessary to assist in cooling the generator, the fan 408 can be started, and under the action of the fan 408, the external air enters the inside of the connecting frame 401 from the air inlet 405. The grille plate 409 can prevent sundries from entering the inside of the connecting frame 401 along with the airflow. The airflow can be guided to move in the connecting frame 401 through the plurality of partitions 404, so that the airflow flows in an S-shaped path, thereby increasing the contact time of the airflow with the cold water pipe 402, facilitating sufficient cooling of the airflow, and ensuring the cooling effect. The cooled gas is discharged from the air outlet 406, then passes through the ventilation opening 407, and finally blows towards the generator from one side of the fan 408. The protective cover 201 can bind the cold air blown out by the fan 408, so that the cold air flows around the generator, thereby facilitating improvement of the cooling effect of the generator. When it is necessary to dismount and clean the filter screen 703, the screw rod 504 can be rotated by rotating the hand-held rotating rod 503. The rotation of the screw rod 504 drives the movement of the moving plate 505. The movement of the moving plate 505 drives the movement of the two valve plates 506. In the movement process of the moving plate 505, the connecting plate 605 moves, so that the second guide shaft 603 moves in the second guide groove 604. When the second guide shaft 603 moves in the first section of the second guide groove 604, the stop rod 602 does not rotate. When the valve plate 506 is about to completely seal the flow channel 502, the second guide shaft 603 moves in the second section of the second guide groove 604. At this time, the stop rod 602 rotates away from the sealing plug 704. When the valve plate 506 completely seals the flow channel 502, the stop rod 602 does not resist the sealing plug 704. Therefore, when the sealing plug 704 is dismounted, the cooling water is prevented from being sprayed due to incomplete sealing of the flow channel 502 by the valve plate 506, thereby effectively improving the safety of the operation. Next, the sealing plug 704 can be twisted off from the connecting cylinder 507, and then the support frame 702 is taken out from the inside of the connecting cylinder 507. The filter screen 703 is taken out together with the support frame 702. After the filter screen 703 is taken out, the dirt attached to the surface of the filter screen 703 can be cleaned, thereby effectively ensuring the filtering effect.

[0043] When the generator needs to be maintained, one of the slide rods 302 can be pulled, the slide rod 302 slides on the two guide seats 301, the two springs 303 are simultaneously contracted, the movement of the slide rod 302 drives the movement of one of the first guide shafts 305 in the first guide slot 306, at this time, the connecting rod 304 rotates, the rotation of the connecting rod 304 drives the movement of the other first guide shaft 305 in the other first guide slot 306, so that the other slide rod 302 moves in the opposite direction, the movement of the slide rod 302 drives the movement of the stop block 307, when the two stop blocks 307 do not resist the connecting strip 203, the support block 308 is rotated to support the slide rod 302, so that after the slide rod 302 is loosened, the spring 303 is prevented from being elongated to cause the stop block 307 to resist the connecting strip 203 again, thereby avoiding the need for one person to always pull the slide rod 302 during the process of disassembling the protective cover 201, thereby effectively improving the convenience of operation, then the protective cover 201 can be moved by holding the two handles 202, when the plug 204 is separated from the connecting strip 203, the protective cover 201 can be taken away from one side of the generator, thereby realizing the quick disassembly of the protective cover 201, thereby facilitating the maintenance of the generator.
