[0016] A method for assembling a waterproof heat dissipation type ship shore power box,

[0017] S1: When the ship's shore power box is working, heat is accumulated inside. When the ship's shore power box is cooled, the servo motor starts to drive the threaded rotating rod to rotate through the main shaft. The upper end of the threaded rotating rod is rotatably connected to the inner side of the upper end of the box shell through the bearing. The rotation of the threaded rotating rod drives the internal threaded plate connected to the outer spiral to move upward. Under the expansion and contraction of the second copper tube assembly and the first copper tube assembly, the internal threaded plate will drive one end of the first copper tube assembly to move upward when the internal threaded plate moves upward. One end of the first copper tube assembly drives multiple second hot copper tubes to move upward at the same time. The second hot copper tube is slidably connected to the opening of the first hot copper tube. The inner side of the tube channel of the second hot copper tube, the third sealing ring fixed on the outer side of the second hot copper tube is fitted with the inner side of the tube channel opened by the first hot copper tube, and the notch column is pushed upward by the elastic force of the pressure spring, and the outer side of the notch column is sealed with the inner side of the bottom copper tube through the first sealing ring. Under the push of the notch column, the water on the upper part of the notch column and the water inside the bottom copper tube enter the inside of the embedded hole groove opened by the water-passing block from the multi-through channels, and the water enters the lower convex connecting tube and the tube channel opened by the first hot copper tube from the embedded hole groove, and then enters the inside of the multiple second hot copper tubes. At this time, the multiple second hot copper tubes and the first hot copper tube are filled with water;

[0018] S2: To realize heat extraction from the inside of the first copper tube assembly and accelerate cooling of the water, the servo motor drives the internal threaded plate to move downward through the threaded rotating rod, and the plurality of second hot copper tubes shrink inside the first hot copper tube, and the notch column moves downward, and the outer side of the notch column slides on the inner side of the bottom copper tube, and the notch column squeezes the sponge against the pressure spring to absorb moisture in the moisture;

[0019] S3: When the internal cooling of the electric box shell is continuously realized, when the multiple first copper tube assemblies shrink, the water inside the first copper tube assembly enters the first heat dissipation and water collection assembly, and the second copper tube assembly at the upper end of the internal thread plate stretches. The structure of the second copper tube assembly is the same as that of the first copper tube assembly, and the connection structure between the second copper tube assembly and the second heat dissipation and water collection assembly is the same as the connection structure between the first copper tube assembly and the first heat dissipation and water collection assembly. After the multiple second copper tube assemblies stretch, the second copper tube assembly dissipates heat inside the electric box shell again;

[0020] S4: When assembling the ship's shore power box to ensure the sealing performance of the ship's shore power box, the first fixing ear seat of the first copper tube assembly is aligned with the threaded holes reserved at the lower end of the power box shell, the lower convex connecting pipe is installed inside the through hole opened in the power box shell, and the first fixing ear seat is fixed to the power box shell. At this time, the fourth sealing ring fixed on the outer side of the lower convex connecting pipe fits with the inner side of the power box shell, the embedded hole groove opened in the water flow block is aligned with the lower convex connecting pipe, the lower convex connecting pipe slides into the embedded hole groove, the outer side of the lower convex connecting pipe fits with the outer side of the fifth sealing ring, and the second fixing ear seat is fixed to the power box shell.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. In the present invention, by providing a driving lifting assembly, a first copper tube assembly and a second copper tube assembly, the device utilizes the heat exchange characteristics of water to absorb and disperse the heat inside the electrical box shell through the water inside the first heat copper tube and the second heat copper tube, thereby effectively achieving heat dissipation inside the ship shore power box, preventing the occurrence of heat spikes, and improving safety during use;

[0023] 2. In the present invention, by providing the electric box shell, the air bag and the electric box shell, the device allows the gas inside the electric box shell to flow to the air bag and expand it. The design effectively alleviates the problem of increased internal pressure due to heat accumulation, prevents the electric box shell from being deformed due to excessive gas pressure, and ensures the sealing and structural integrity of the electric box;

[0024] 3. In the present invention, by providing a servo motor, an auxiliary heat dissipation assembly and a first copper tube assembly, the servo motor is started in reverse and the notch column is pushed downward by water pressure, so that the heat inside the first copper tube assembly is extracted and the cooling speed of the water is accelerated, so that the inside of the electric box shell can be cooled again;

[0025] 4. In the present invention, by providing the first copper tube assembly, the second copper tube assembly and the second heat dissipation and water collection assembly, the device makes the first copper tube assembly and the second copper tube assembly contract and stretch alternately, and the internal water flows circulate, thereby realizing continuous cooling of the inside of the electrical box shell of the ship shore power box, ensuring the safety of the electrical box shell during continuous use;

[0026] 5. In the present invention, by setting the control cover plate, the first screw, the second fixing ear seat and the first fixing ear seat, the device realizes a modular assembly structure, ensures the sealing performance of the ship shore power box shell, prevents the entry of moisture and pollutants, ensures the safety of internal components and the reliability of the equipment, and enables the ship shore power box to be easily disassembled and reinstalled during later maintenance.

The first heat dissipation and water collecting assembly 7 is installed inside the lower protective shell 9. The bottom copper tube 774 is in the shape of a hollow cylinder. The top end of the bottom copper tube 774 is fixed to the bottom end of the embedded hole groove 72 opened in the water passing block 71. The inner side of the bottom copper tube 774 is connected to the embedded hole groove 72 opened in the water passing block 71. The outer side of the notch column 777 is fitted with the inner side of the bottom copper tube 774. The outer side of the first sealing ring 778 is fitted with the inner side of the bottom copper tube 774. The constant pressure air hole 779 opened in the bottom film 775 is connected to the inside of the bottom copper tube 774. Through precise heat control and water evaporation, effective extraction and heat dissipation of internal heat are achieved, thereby improving the adaptability of the system.

[0061] Working process: when the ship shore power box is working, heat is accumulated inside. When the heat is dissipated inside the ship shore power box, when the assembled ship shore power box is used, the inside of the power box shell 31 is in a sealed state. When heat is accumulated inside the power box shell 31, the gas inside the power box shell 31 expands and contracts due to heat. At this time, the pressure inside the power box shell 31 increases. The gas inside the power box shell 31 flows into the air bag 374 from the upper channel 376 opened by the upper through pipe 375. The air bag 374 expands. At this time, the pressure inside the power box shell 31 can be reduced to prevent the power box shell 31 from being deformed due to the high air pressure inside the power box shell 31, thereby affecting the sealing performance of the power box shell 31. When the air bag 374 expands, it will deform and stretch upwards. When the airbag 374 touches the pressure sensor 373, the controller arranged inside the electric box shell 31 receives a signal, and the controller inside the electric box shell 31 controls the servo motor 41 to start. When the airbag 374 continues to deform, it will push the pressure sensor 373 and the connecting plate 372 to move upward, and the connecting plate 372 drives the spring telescopic rod 371 to stretch, which does not affect the continuous pressure relief inside the electric box shell 31. The servo motor 41, the control inside the electric box shell 31 and the pressure sensor 373 are electrically connected. When the servo motor 41 starts, it drives the threaded rotating rod 42 to rotate through the main shaft. The upper end of the threaded rotating rod 42 is rotatably connected to the inner side of the upper end of the electric box shell 31 through the bearing. The rotation of the threaded rotating rod 42 drives the inner threaded plate 43 connected to the outer spiral upward The inner thread plate 43 is used to limit the movement direction of the inner thread plate 43 under the expansion and contraction effect of the second copper tube assembly 6 and the first copper tube assembly 5. When the inner thread plate 43 moves upward, one end of the first copper tube assembly 5 will be driven to move upward, and one end of the first copper tube assembly 5 will drive multiple second hot copper tubes 53 to move upward at the same time. The second hot copper tube 53 is slidably connected to the inner side of the tube hole 52 opened in the first hot copper tube 51, and the third sealing ring 54 fixed on the outside of the second hot copper tube 53 is fitted with the inner side of the tube hole 52 opened in the first hot copper tube 51, so as to seal the second hot copper tube 53 and the first hot copper tube 51, so as to prevent the water inside the first hot copper tube 51 and the multiple second hot copper tubes 53 from overflowing to the outside. When the second hot copper tube 53 moves upward, the notch column 777 is pushed upward by the elastic force of the pressure spring 776. The outer side of the notch column 777 is sealed with the inner side of the bottom copper tube 774 through the first sealing ring 778. Under the push of the notch column 777, the water on the upper part of the notch column 777 and the water inside the bottom copper tube 774 enter the embedded hole groove 72 opened in the water passing block 71 from the multi-through channel 74. The external air will enter the lower part of the notch column 777 and the bottom copper tube 774 from the constant pressure air hole 779, which can balance the gas pressure inside the bottom copper tube 774 and the lower part of the notch column 777. The fifth sealing ring 73 plays a role in sealing between the water passing block 71 and the lower convex connecting tube 55 to prevent the water inside the embedded hole groove 72 from overflowing to the outside.Water enters the interior of the tube channel 52 opened by the lower convex connecting tube 55 and the first thermal copper tube 51 from the embedded hole groove 72, and then enters the interior of the plurality of second thermal copper tubes 53. At this time, the interior of the plurality of second thermal copper tubes 53 and the first thermal copper tube 51 are filled with water. At the same time, the second thermal copper tubes 53 and the first thermal copper tube 51 are located inside the electric box shell 31 and close to the electrical equipment inside the electric box shell 31. The heat inside the electric box shell 31 is absorbed by the first thermal copper tube 51 and the second thermal copper tube 53. The water inside the first thermal copper tube 51 and the second thermal copper tube 53 exchanges the heat of the second thermal copper tube 53 and the first thermal copper tube 51, thereby achieving the effect of heat dissipation inside the electric box shell 31. After the interior of the electric box shell 31 is cooled down, the airbag 374 restores its shape. At the same time, the multi-through channel 74 is away from the pressure sensor 373, so as to prevent the occurrence of thermal spikes that increase the risk of using the ship shore power box, and reduce the occupation of the internal space of the electric box shell 31.

[0062] To realize heat extraction from the inside of the first copper tube assembly 5 and accelerate cooling of the water, when heat accumulates again inside the electrical box shell 31, the airbag 374 contacts the pressure sensor 373 again, and is recognized by the controller inside the electrical box shell 31. At this time, the servo motor 41 is started in reverse. The main shaft of the servo motor 41 rotates in the opposite direction to the main shaft of the above principle. The servo motor 41 drives the internal threaded plate 43 to move downward through the threaded rotating rod 42. At this time, multiple second hot copper tubes 53 shrink inside the first hot copper tube 51. One end of the first copper tube assembly 5 is solid, which is convenient for pushing the water inside the first copper tube assembly 55 from the tube channel 52 opened in the first hot copper tube 51 into the interior of the lower convex connecting tube 55, and from the interior of the lower convex connecting tube 55 into the interior of the embedded hole groove 72 and the multi-pass channel 74, and from the interior of the multi-pass channel 74 into the interior of each bottom copper tube 774. At this time, the notch column 777 is pushed downward under the action of water pressure, and the outer side of the notch column 777 slides on the inner side of the bottom copper tube 774. The shape of 777 is a cylinder, which can improve the stability of the notch column 777 when it moves. The notch column 777 squeezes the pressure spring 776. At this time, water is stored in the bottom copper tube 774. Due to the high humidity on the shore, the moisture will enter the lower protective shell 9 from the convection hole 11 opened in the lower protective shell 9, and then contact with the sponge 771. The sponge 771 absorbs the moisture in the moisture. After the water enters the bottom copper tube 774, since the water is hot, the water will transfer the heat to the bottom copper tube 774 and The mesh tube 772 is used to fix the sponge 771. When the sponge 771 is heated, the water inside the sponge 771 will evaporate, and the evaporation of water will absorb heat, thereby taking away the heat on the bottom copper tube 774 and the mesh tube 772. The air vents 773 provided in the mesh tube 772 facilitate the heat dissipation of the bottom copper tube 774, thereby achieving the effect of heat dissipation of the water inside the bottom copper tube 774, improving the cooling speed of the water heat dissipation, and facilitating cooling the inside of the electric box shell 31 again;

[0063] When realizing continuous cooling of the inside of the electric box shell 31, the same principle as above, when the multiple first copper tube assemblies 5 shrink, the water inside the first copper tube assembly 5 enters the inside of the first heat dissipation and water collection assembly 7, and at this time, the second copper tube assembly 6 at the upper end of the internal threaded plate 43 stretches, and the structure of the second copper tube assembly 6 is the same as that of the first copper tube assembly 5. At the same time, the connection structure between the second copper tube assembly 6 and the second heat dissipation and water collection assembly 8 is the same as the connection structure between the first copper tube assembly 5 and the first heat dissipation and water collection assembly 7. When the multiple second copper tube assemblies 6 stretch, the second copper tube assembly 6 dissipates heat to the inside of the electric box shell 31 again, and the water inside the second heat dissipation and water collection assembly 8 enters the inside of the second copper tube assembly 6, thereby realizing the effect of alternating heat dissipation inside the electric box shell 31, and ensuring the safety of the electric box shell 31 during continuous use;

[0064] When assembling the ship's shore power box to ensure the sealing performance of the ship's shore power box, first assemble the first copper tube assembly 5 and the second copper tube assembly 6 inside the power box shell 31, align the first fixing ear seat 57 of the first copper tube assembly 5 with the threaded holes reserved at the lower end of the power box shell 31, and install it inside the through hole 34 opened in the power box shell 31 through the lower convex connecting tube 55, and fix the first fixing ear seat 57 and the power box shell 31 through the second screw 58. At this time, the fourth sealing ring 56 fixed on the outside of the lower convex connecting tube 55 fits with the inner side of the power box shell 31, which plays a role in sealing between the lower convex connecting tube 55 and the power box shell 31. After the second copper tube assembly 6 is fixed to the power box shell 31 according to the above principle, after the installation inside the power box shell 31 is completed, install it on the outside of the power box shell 31, align the embedded hole groove 72 opened in the water-passing block 71 with the lower convex connecting tube 55, slide the lower convex connecting tube 55 into the embedded hole groove 72, so that the lower convex The outer side of the connecting pipe 55 fits with the outer side of the fifth sealing ring 73, and the second fixing ear seat 75 and the electric box shell 31 are fixed by the third screw 76. After the installation is completed, the second heat dissipation and water collecting assembly 8 is installed according to the above principle. At this time, the rear end of the control cover 1 is buckled on the outer side of the convex ring 32. At this time, the rubber sleeve 33 fixed on the outer side of the convex ring 32 fits with the inner side of the rear end of the control cover 1, and the control cover 1 and the electric box shell 31 are fixed by the first screw 2. The upper protective shell 14 is sleeved on the outside of the second heat dissipation and water collecting assembly 8, and the upper protective shell 14 and the electric box shell 31 are fixed by bolts, and then the wire release tube 10 is welded to the bottom end of the electric box shell 31, and the lower protective shell 9 is sleeved on the outside of the wire release tube 10 and the outside of the first heat dissipation and water collecting assembly 7. The lower protective shell 9 and the electric box shell 31 are fixed by bolts, and then the bracket rod 12 and the lower protective shell 9 are welded to complete the installation. After installation, the sealing performance of the ship shore power box is ensured, and later maintenance is convenient.
