[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0024] like Figures 1 to 3As shown in the figure, a phase-shifting rectifier transformer for a cruise ship power system according to an embodiment of the present invention includes a protective box 1; two support grooves 10 are formed in the side wall of the protective box 1; the two support grooves 10 are arranged inside the protective box 1; the two support grooves 10 are arranged oppositely; two pulleys 11 are installed on the side wall of the protective box 1; the pulleys 11 are arranged in the middle of the support grooves 10; two handles 14 are installed in the middle of the two pulleys 11; two sliding grooves 13 are formed in the side wall of the placing plate 12; the two sliding grooves 13 are arranged oppositely; the two pulleys 11 are arranged inside the corresponding sliding grooves 13; the two pulleys 11 are slidably connected inside the sliding grooves 13; a handle 14 is fixedly connected to the middle of the placing plate 12; a transformer body 15 is installed on the top of the placing plate 12; a protective door 16 is installed on the side wall of the protective box 1; an observation window 17 is formed in the middle of the protective door 16; during operation, when connecting the transformer body 15 to the cruise ship power system, first place the protective box 1 at a designated position, open the protective door 16, hold the handle 14 and pull the placing plate 12 outwards. At the same time, during the movement of the placing plate 12, the two side pulleys 11 rotate in the middle of the sliding grooves 13. The two sides of the placing plate 12 slide in the middle of the support grooves 10 and the support grooves 10 support the placing plate 12 inside the protective box 1. After pulling the placing plate 12 out of the protective box 1, place the transformer body 15 in the middle of the placing plate 12. After the placement of the transformer body 15 is completed, connect it to the cruise ship power system, and then push the placing plate 12 into the protective box 1 through the handle 14, so as to place the transformer body 15 inside the protective box 1. Rotate the protective door 16 to close it. The transformer body 15 is protected by the protective box 1 during use. The observation window 17 is made of transparent material, and the working state of the transformer body 15 can be directly observed through the observation window 17. In this step, through the protective box 1, when the cruise ship is sailing and facing various harsh weather conditions, it can effectively reduce the entry of dust and moisture into the transformer body 15, reduce the corrosion of metal components in the transformer body 15 caused by the high humidity and salt mist environment at sea, effectively isolate the external environment from eroding the transformer body 15, reduce the problems of performance degradation or electrical faults of the transformer body 15, effectively extend the service life of the transformer body 15, and through the movement of the placing plate 12 inside the protective box 1, when the transformer body 15 is maintained and repaired, it is convenient to pull out the inside of the protective box 1, reduce the problems of collision or inconvenient operation during the process of moving the transformer body 15 out of the protective box 1, and can effectively improve the efficiency of the maintenance and repair work of the transformer body 15.
[0025] As Figures 1 to 3As shown, a cooling box 2 is fixedly connected to the side wall of the protection box 1; a drain pipe 21 is fixedly connected to the middle of the cooling box 2; a water storage chamber 23 is formed in the middle of the protection box 1; the end of the drain pipe 21 penetrates through the side wall of the protection box 1; a water suction pipe 22 is fixedly connected to the middle of the cooling box 2; the end of the water suction pipe 22 penetrates through the side wall of the protection box 1; the ends of the drain pipe 21 and the water suction pipe 22 are both arranged inside the water storage chamber 23; a water inlet pipe 24 is fixedly connected to the top of the protection box 1; the water inlet pipe 24 is arranged at the top position of the water storage chamber 23; during operation, during the use of the transformer body 15, heat is dissipated into the protection box 1, low-temperature water is placed inside the water storage chamber 23 from the end of the water inlet pipe 24 for storage, the heat inside the protection box 1 causes the temperature of the side wall to rise, the temperature inside the protection box 1 is transferred to the water through the side wall of the protection box 1, and heat conversion is carried out through the water. When the water dissipates heat inside the protection box 1, the water temperature will rise. The cooling box 2 is turned on, and the circulation pump inside the cooling box 2 pumps out the water in the water storage chamber 23 through the water suction pipe 22, cools the water through the cooling box 2, and then discharges it into the water storage chamber 23 through the drain pipe 21, realizing the heat dissipation of the transformer body 15 during its operation. This step can effectively absorb and take away the heat generated by the transformer body 15 during its operation inside the protection box 1 through the heat capacity and thermal conductivity of the water, can achieve rapid cooling, effectively keep the transformer body 15 operating at a lower working temperature, can continuously provide a low-temperature water source for the inside of the water storage chamber 23 by circulating the water through the cooling box 2, can effectively maintain the continuity and stability of the cooling effect, effectively reduce the thermal stress caused by the high temperature inside the protection box 1 on the insulating material and internal structure of the transformer body 15, and reduce the problems of shutdown or damage caused by the too high temperature of the transformer body 15.
[0026] As Figure 2 and Figure 4As shown, a plurality of telescopic rods 3 are fixedly connected to the bottom of the placement plate 12; a plurality of springs 31 are fixedly connected to the bottom of the placement plate 12; the springs 31 are arranged outside the corresponding telescopic rods 3; a guide plate 32 is fixedly connected to the ends of the telescopic rods 3 and the springs 31; the guide plate 32 is arc-shaped; the guide plate 32 is elastically arranged; during operation, when the placement plate 12 drives the guide plate 32 to be pulled out from the inside of the protection box 1, the spring 31 undergoes elastic stretching, and at the same time drives the end of the telescopic rod 3 to be stretched outwards. When the transformer body 15 is placed on the placement plate 12 and moves towards the inside of the protection box 1, first, it contacts the bottom of the protection box 1 through the guide plate 32. During continuous movement, the guide plate 32 presses against the placement plate 12 and fits the bottom of the protection box 1 to move, and at the same time, the telescopic rod 3 and the spring 31 are elastically contracted under pressure. When the transformer body 15 is in use, the telescopic rod 3 and the spring 31 absorb the vibration generated by the mechanical force during the operation of the transformer body 15. This step has good buffering performance through the combined use of the telescopic rod 3 and the spring 31. When the cruise ship encounters wind and waves or vibrations during navigation, it can reduce the impact of vibrations on the transformer body 15, effectively reduce the damage to the internal structure and electrical components of the transformer body 15 caused by vibrations, effectively reduce the wear degree of the internal components of the transformer body 15, and effectively improve the overall stability and reliability of the transformer body 15 during operation.
[0027] As Figure 2 and Figure 4 shown, a plurality of grooves 4 are formed in the middle of the guide plate 32; the plurality of grooves 4 are equidistantly distributed in the middle of the guide plate 32; a roller 41 is rotatably connected to the middle of the groove 4; during operation, when the guide plate 32 is moving, first, it contacts the bottom of the protection box 1 through the roller 41. When the spring 31 is moving, the roller 41 fits and rotates with the bottom of the protection box 1 inside the groove 4. This step can reduce the frictional loss between the guide plate 32 and the bottom support surface of the protection box 1 through the roller 41, effectively reduce the resistance generated by the frictional force, and can reduce the accumulation of wear particles and impurities generated by friction, so as to effectively make the placement plate 12 move more smoothly. And through the roller 41, the guide plate 32 can be made more stable during movement, and effectively reduce the noise generated by friction.
[0028] As Figure 1 , Figure 2 , Figure 5As shown, two ventilation pipes 5 are fixedly connected to the top of the protection box 1; the bottoms of the two ventilation pipes 5 penetrate through the top of the protection box 1; two fixing rods 51 are fixedly connected to the middle of the ventilation pipe 5; two ends of the two fixing rods 51 are fixedly connected with a motor 52; the output end of the motor 52 is fixedly connected with a cooling fan 53; during operation, when the transformer body 15 operates inside the protection box 1, the motor 52 is powered on and started, and the cooling fan 53 is driven to rotate through the output end of the motor 52. One of the cooling fans 53 sucks the air flow outside the protection box 1 and discharges it into the protection box 1, and the other cooling fan 53 rotates in the reverse direction to extract the air flow inside the protection box 1 and discharge it outside the protection box 1. The air inside the protection box 1 is circulated through the cooling fan 53. This step enables the air to smoothly enter and exit the protection box 1 through the two cooling fans 53, effectively reducing the temperature inside the protection box 1, accelerating the air flow speed inside the protection box 1, and at the same time discharging the humid air inside the protection box 1. The dry air introduced by one of the cooling fans 53 can accelerate the evaporation process of the humid moisture inside the protection box 1, effectively reducing the damage of the high-humidity environment to the transformer body 15 and the internal electrical components.
[0029] As Figure 1 , Figure 2 , Figure 5 shown, a fixing cylinder 6 is threadedly connected to the middle of the ventilation pipe 5; a mesh cover 61 is fixedly connected to the top of the fixing cylinder 6; the mesh cover 61 is arranged outside the ventilation pipe 5; during operation, the fixing cylinder 6 is placed outside the ventilation pipe 5 and rotated, and the fixing cylinder 6 is fixed to the middle of the ventilation pipe 5 through the thread. The top of the ventilation pipe 5 is protected by the mesh cover 61, and the dust and impurities in the external air are intercepted. This step can effectively fix the mesh cover 61 at the end of the ventilation pipe 5 through the tight connection between the fixing cylinder 6 and the ventilation pipe 5. The mesh cover 61 can effectively block the external dust and impurities from entering the protection box 1 through the ventilation pipe 5, effectively reducing the dust and impurities from entering the protection box 1 and adhering to the surface of the transformer body 15, and effectively reducing the problems of wear and corrosion caused by the accumulation of dust and impurities on the surface of the transformer body 15. The fixing cylinder 6 can be removed for cleaning when the mesh cover 61 accumulates dust and impurities, thereby effectively maintaining the smoothness of the ventilation pipe 5.
[0030] As Figure 1 and Figure 3As shown, a heat insulation pad 7 is fixedly connected to the side wall of the protection box 1; a sponge pad 71 is fixedly connected to the side wall of the heat insulation pad 7; the sponge pad 71 is arranged on the side close to the protection box 1; during operation, when water cools the inside of the protection box 1 in the water storage chamber 23, the heat insulation pad 7 isolates the temperature inside the protection box 1 from the outside air, and the sponge pad 71 absorbs the noise generated by the operation of the transformer body 15 inside the protection box 1. This step can effectively reduce the heat exchange between the transformer body 15 and the external environment through the heat insulation pad 7, effectively maintaining the stability of the temperature inside the protection box 1. The sponge pad 71 can effectively absorb the mechanical stress and noise caused by the vibration of the transformer body 15 during operation, effectively reducing the noise level during the operation of the transformer body 15 and improving the overall quietness, thereby increasing the comfort of the working environment.
[0031] When the transformer body 15 is connected to the cruise ship power system during operation, first place the protection box 1 at the designated position, open the protection door 16, hold the handle 14 and pull the placement plate 12 outwards. At the same time, during the movement of the placement plate 12, the pulleys 11 on both sides are driven to rotate in the middle of the sliding groove 13. The two sides of the placement plate 12 slide in the middle of the support groove 10, and the placement plate 12 is supported inside the protection box 1 through the support groove 10. After the placement plate 12 is pulled out of the protection box 1, place the transformer body 15 in the middle of the placement plate 12. After the placement of the transformer body 15 is completed, connect it to the cruise ship power system, and then push the placement plate 12 into the protection box 1 through the handle 14, so as to place the transformer body 15 inside the protection box 1. Rotate the protection door 16 to close it. The transformer body 15 is protected by the protection box 1 during use. The observation window 17 is made of transparent material, and the working state of the transformer body 15 can be directly observed through the observation window 17. During the use of the transformer body 15, heat is dissipated into the protection box 1. Place low-temperature water at the end of the water inlet pipe 24 inside the water storage chamber 23 for storage. The heat inside the protection box 1 causes the temperature of the side wall to rise. The temperature inside the protection box 1 is transferred to the water through the side wall of the protection box 1, and heat conversion is carried out through the water. When the water dissipates heat inside the protection box 1, the water temperature will rise. Open the cooling box 2. The circulation pump inside the cooling box 2 pumps out the water in the water storage chamber 23 through the water extraction pipe 22, cools the water through the cooling box 2, and then discharges it back into the water storage chamber 23 through the drain pipe 21, realizing the heat dissipation of the transformer body 15 during operation. When the placement plate 12 drives the guide plate 32 to be pulled out of the protection box 1, the spring 31 produces elastic stretching, and at the same time drives the end of the telescopic rod 3 to stretch outwards. When the transformer body 15 is placed on the placement plate 12 and moves towards the protection box 1, first, the guide plate 32 contacts the bottom of the protection box 1. When continuously moving, the guide plate 32 presses against the placement plate 12 and moves along the bottom of the protection box 1. At the same time, the telescopic rod 3 and the spring 31 are elastically contracted under pressure. When the transformer body 15 is in use, the telescopic rod 3 and the spring 31 absorb the vibration generated by the mechanical force during the operation of the transformer body 15. When the guide plate 32 moves, first, the roller 41 contacts the bottom of the protection box 1. When the spring 31 moves, the roller 41 fits and rotates with the bottom of the protection box 1 inside the groove 4. When the transformer body 15 operates inside the protection box 1, energize the motor 52 and turn it on. The output end of the motor 52 drives the cooling fan 53 to rotate. One of the cooling fans 53 sucks the air outside the protection box 1 and discharges it into the protection box 1, and the other cooling fan 53 rotates in the opposite direction to extract the air inside the protection box 1 and discharge it outside the protection box 1. The air inside the protection box 1 is circulated through the cooling fan 53. Place the fixing cylinder 6 outside the ventilation pipe 5 and rotate it, and fix the fixing cylinder 6 in the middle of the ventilation pipe 5 through the thread. Protect the top of the ventilation pipe 5 through the mesh cover 61.Intercept dust and impurities in the external air. When water cools the inside of the protection box 1 in the water storage chamber 23, the temperature inside the protection box 1 is isolated from the outside air through the heat insulation pad 7, and the sponge pad 71 absorbs the noise generated when the transformer body 15 operates inside the protection box 1.,
