DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0031] Please refer to Figures 1 to 7 The present application provides a technical solution:

[0032] An energy-saving cooling device for deceleration and energy storage of an electric ship's electric drive pod includes a tank 11. A sealing plate 22 is fixedly connected to the inner surface of the tank 11. An energy storage tank 20 is fixedly connected to the outer surface of the upper end of the sealing plate 22. A fixing sleeve 26 is fixedly connected to the outer surface of the lower end of the tank 11. A heat dissipation component is provided on the outer surface of the fixing sleeve 26. The heat dissipation component includes an air inlet groove 30 opened on the outer surface of the fixing sleeve 26. A sealing groove 31 is embedded in the inner side of the air inlet groove 30. A sealing block 32 is slidably connected to the inner side of the sealing groove 31. A pushing part is provided on the lower side of the sealing block 32. The pushing part is used to drive the sealing block 32 to move up and down reciprocally.

[0033] The propulsion unit includes a mounting groove 42 formed on the lower outer surface of the sealing block 32. An expansion block 43 is fixedly connected to the upper end of the inner surface of the mounting groove 42. The lower outer surface of the expansion block 43 is fixedly connected to the inner surface of the sealing groove 31. A cavity 33 is embedded in the inner side of the sealing block 32. The cavity 33 is filled with thermal expansion gas. There are several groups of air inlet grooves 30 and sealing blocks 32, which are arranged in a ring array. A pressure sensor 44 is fixedly connected to the lower outer surface of the sealing block 32.

[0034] A tank cover 17 is snapped onto the upper outer surface of the tank body 11. A wire 18 is electrically connected to the upper outer surface of the energy storage tank 20. The wire 18 passes through to the upper side of the tank cover 17. A support plate 12 is fixedly connected to the outer surface of the tank body 11. A bottom plate 13 is fixedly connected to the lower outer surface of the support plate 12. The number of support plates 12 and bottom plates 13 are several sets and distributed in a ring array. A ventilation component is provided inside the fixing sleeve 26.

[0035] By adopting the above technical solution, when cooling the electric drive pod deceleration energy storage system using an energy-saving cooling device, a heat dissipation component is installed to maintain the operating temperature of the deceleration energy storage equipment within an appropriate range. The base plate 13 supports the tank 11 via the support plate 12. The fixing sleeve 26 is connected to the inside of the tank 11 to allow normal air circulation. The tank cover 17 is used to seal the tank 11. The wire 18 ensures stable power transmission. The tank 11 is fixedly supported by the sealing plate 19 and the sealing plate 22, thereby providing a certain degree of safety protection for the energy storage tank 20. As a result, when the temperature of the energy storage tank 20 rises during long-term operation, the heat inside the tank body 11 will be transferred to the fixed sleeve 26 with the air. The cavity 33 inside the expansion block 43 is filled with an appropriate amount of thermal expansion gas. When the thermal expansion gas is heated, its volume will increase. At this time, the thermal expansion gas will drive the expansion block 43 to increase its volume. The expansion block 43 will push the sealing block 32 upward through the receiving groove. At this time, the sealing block 32 will slide upward inside the sealing groove 31. When the sealing block 32 moves to the upper side of the air inlet groove 30, the external air will pass through the fixed sleeve 26, thereby achieving a good heat dissipation and cooling effect on the energy storage tank 20.

[0036] The sealing block 32 drives the pressure sensor 44 on the lower side to move synchronously during movement. When the lower end of the pressure sensor 44 is out of contact with the lower side of the sealing groove 31, the pressure detected by the pressure sensor 44 disappears. At this time, an electrical signal is sent to the control system to start the movement of the ventilation assembly. The circulation of air in the tank body 11 can achieve a certain heat dissipation effect on the energy storage tank 20. When the temperature inside the tank body 11 decreases, the thermal expansion gas and the volume of the expansion block 43 will gradually shrink. At this time, the sealing block 32 will move downward along the sealing groove 31 under the action of gravity. The sealing block 32 can seal the air inlet groove 30. When the temperature inside the tank body 11 is low, the heat loss can be effectively reduced, so that the temperature inside the tank body 11 can be maintained within an appropriate range. Under the blocking action of the sealing block 32, the external dust and moisture can enter the tank body 11 to a certain extent, thereby reducing the influence of dust on the heat dissipation effect of the energy storage system.

[0037] During the downward movement of the sealing block 32, the pressure sensor 44 will contact the sealing groove 31 again. After detecting the pressure, the pressure sensor 44 sends an electrical signal to the control system. The control system controls the ventilation assembly to stop running. By setting the heat dissipation assembly, the start and stop of the ventilation assembly can be controlled according to the temperature change inside the tank body 11, so that the continuous work of the ventilation assembly when the temperature inside the tank body 11 is appropriate can be avoided, which not only can maintain the temperature inside the tank body 11 within an appropriate range, but also can improve the utilization efficiency of electric energy, thereby effectively improving the energy-saving effect of the cooling device.

[0038] Specifically, as shown in Figure 4 The inside of the fixed sleeve 26 is provided with a ventilation assembly. The ventilation assembly includes a motor 27 fixedly connected with the outer surface of the lower end of the fixed sleeve 26. The output shaft of the motor 27 is fixedly connected with a drive rod 28. The drive rod 28 penetrates into the inside of the tank body 11 and is rotatably connected with the fixed sleeve 26. The outer surface of the drive rod 28 is fixedly connected with a fan blade 29. The upper side of the outer surface of the tank body 11 is provided with a plurality of groups of air outlet holes 16 arranged in a ring array.

[0039] By adopting the above technical scheme, when the ventilation assembly works, the motor 27 is started to move. The output shaft of the motor 27 drives the drive rod 28 to rotate synchronously. The drive rod 28 drives the paddle to rotate at a high speed, so as to inject the air in the fixed sleeve 26 into the tank body 11. Under the action of the gas pressure, the air outside the tank body 11 is sucked into the fixed sleeve 26 through the air inlet groove 30. Then, the gas in the tank body 11 is discharged outward through the air outlet holes 16 on the surface of the tank body 11. The circulation of the gas in the tank body 11 can discharge the heat in the tank body 11 outward, so as to achieve air cooling of the energy storage tank 20, thereby effectively improving the stability of the cooling device during operation.

[0040] Specifically, as shown in Figure 4 With Figure 7 As shown, the inside of the tank body 11 is provided with a cooling assembly, which includes a sealing plate one 19 fixedly connected with the inner surface of the tank body 11, the sealing plate one 19 is located on the upper side of the sealing plate two 22, and the sealing plate one 19 and the sealing plate two 22 are provided with a material conveying pipe 21, the inside of the material conveying pipe 21 is hollow and spirally distributed, the outer surface of the material conveying pipe 21 is in contact with the inner surface of the energy storage tank 20 and the tank body 11 respectively, and the material conveying pipe 21 is made of heat-conducting material.

[0041] The upper and lower ends of the material conveying pipe 21 respectively penetrate to the outside of the sealing plate one 19 and the sealing plate two 22, the left side of the outer surface of the tank body 11 is fixedly connected with the liquid inlet pipe 14 and the liquid outlet pipe 15, the liquid inlet pipe 14 is located directly above the liquid outlet pipe 15, and the liquid inlet pipe 14 and the liquid outlet pipe 15 are located between the sealing plate one 19 and the sealing plate two 22.

[0042] By adopting the above technical scheme, in order to further improve the heat dissipation effect of the energy storage tank 20, the cooling assembly is arranged, the material conveying pipe 21 is spirally in contact with the outer surface of the energy storage tank 20, the heat of the energy storage tank 20 can be conducted and absorbed by the material conveying pipe 21, when working, the external air is injected into the inside of the tank body 11 by the ventilation assembly, the gas will enter the inside of the material conveying pipe 21 under the action of pressure, the gas flows spirally upward in the inside of the material conveying pipe 21, which not only effectively prolongs the flowing time of the gas in the inside of the tank body 11, but also effectively increases the contact area with the material conveying pipe 21, thereby effectively improving the heat dissipation efficiency of the energy storage tank 20, and then the cooling liquid is injected between the sealing plate one 19 and the sealing plate two 22 through the liquid inlet pipe 14, the cooling liquid spirally flows downward outside the material conveying pipe 21, and the cooling liquid is discharged to the outside of the tank body 11 through the liquid outlet pipe 15 after flowing to the upper side of the sealing plate two 22, the cooling liquid contacts the outer surface of the energy storage tank 20, which can absorb the heat of the energy storage tank 20, and the air cooling and liquid cooling are combined to cool the energy storage tank 20 by the cooling liquid and the air, which not only effectively improves the cooling speed of the energy storage tank 20, but also maintains the stability of the temperature in the inside of the tank body 11, thereby further improving the operation reliability of the energy storage system cooling device.

[0043] Specifically, as shown in Figure 4 With Figure 6 As shown, the inside of the fixed sleeve 26 is provided with a refrigeration assembly, which includes a refrigeration plate 38 fixedly connected with the outer surface of the driving rod 28, the number of the refrigeration plate 38 is several groups and is arranged in a ring shape, the outer surface of the refrigeration plate 38 is uniformly provided with a mesh 39, and the refrigeration plate 38 is located on the upper side of the fan blade 29.

[0044] By adopting the above technical scheme, the driving rod 28 will drive the refrigeration plate 38 to rotate synchronously in the rotating process. When the air is injected from the inside of the fixed sleeve 26 to the inside of the tank body 11, the air will be in contact with the refrigeration plate 38. The refrigeration plate 38 will disturb the air in the rotating process, so that the air can fully contact the surface of the refrigeration plate 38. The temperature of the air can be reduced by the refrigeration plate 38, thereby further improving the heat dissipation effect of the energy storage tank 20. The mesh holes 39 on the surface of the refrigeration plate 38 can not only increase the contact area between the refrigeration plate 38 and the air to improve the air cooling effect, but also make the air flow irregularly, thereby further improving the uniformity of the air and the refrigeration plate 38.

[0045] Specifically, as shown in Figure 4 With Figure 6 As shown, the lower side of the sealing plate two 22 is provided with a filter assembly. The filter assembly includes a gas guide plate 23 fixedly connected to the outer surface of the lower end of the sealing plate two 22. The gas guide plate 23 is conical. The outer surface of the lower end of the sealing plate two 22 is fixedly connected with a mesh plate 24. The outer surface of the lower end of the mesh plate 24 is fixedly connected with the inner surface of the lower end of the tank body 11. The mesh plate 24 is distributed in a circular ring shape.

[0046] The inner surface of the fixed sleeve 26 is fixedly connected with a pull rod 41. The driving rod 28 penetrates through the upper side of the pull rod 41 and is in rotational contact with the pull rod 41. The upper end of the outer surface of the pull rod 41 is fixedly connected with a guide rod 25. The outer surface of the guide rod 25 is slidingly connected with a scraper 34. The outer surface of the scraper 34 is in sliding contact with the inner wall of the mesh plate 24. The inner surface of the fixed sleeve 26 is fixedly connected with a limiting plate 35. The limiting plate 35 is in a circular ring shape and is located on the lower side of the scraper 34.

[0047] The outer surface of the driving rod 28 is fixedly connected with a contact plate two 40. The upper end of the outer surface of the pull rod 41 is rotatably connected with a reciprocating screw rod 37. The reciprocating screw rod 37 is in screw transmission connection with the scraper 34. The lower side of the outer surface of the reciprocating screw rod 37 is fixedly connected with a contact plate one 36. The number of the contact plate one 36 is several groups and is distributed in a ring array. The outer surface of the contact plate one 36 is in rotational contact with the contact plate two 40.

[0048] By adopting the above technical scheme, when the ventilation assembly injects air into the inside of the tank body 11, the air will contact the surface of the mesh plate 24, and the mesh plate 24 can filter the dust in the air to reduce the dust adhering to the inner wall of the conveying pipe 21 and the tank body 11 to affect the heat transfer. Therefore, the filtering assembly is arranged, and the driving rod 28 will drive the contact plate two 40 to move synchronously in the rotating process. The contact plate two 40 can contact the outer surface of the contact plate one 36 to move the contact plate one 36, so that the contact plate one 36 drives the reciprocating screw rod 37 to rotate, the pull rod 41 supports the reciprocating screw rod 37 to rotate, the scraper 34 is connected with the reciprocating screw rod 37 in a screw transmission mode, and the reciprocating screw rod 37 drives the scraper 34 to reciprocate upward in the rotating process. The guide rod 25 is connected with the scraper 34 in a sliding mode, and can guide the scraper 34 well, so that the sliding plate moves more stably. The sliding plate will slide with the inner surface of the mesh plate 24 in the moving process, and the reciprocating movement of the scraper 34 can scrape and clean the dust on the inner wall of the mesh plate 24. The scraper 34 can not only prolong the working time of the mesh plate 24 to a certain extent, but also keep the mesh plate 24 always transparent, so that the cleaning effect of the mesh plate 24 on the dust can be ensured. The limiting plate 35 at the lower side of the scraper 34 can limit the scraper 34 to a certain extent.

[0049] Working principle: when the temperature of the energy storage tank 20 rises in the long-time working process, the overheat expansion gas drives the expansion block 43 to increase in volume, the expansion block 43 drives the sealing block 32 upward through the receiving groove, and when the lower end of the pressure sensor 44 is separated from the lower side of the sealing groove 31, the pressure detected by the pressure sensor 44 disappears. At this time, the control system sends an electrical signal to start the ventilation assembly to move, the driving rod 28 drives the paddle to rotate at high speed, so that the air in the fixed sleeve 26 is injected into the inside of the tank body 11. When the air is injected from the inside of the fixed sleeve 26 into the inside of the tank body 11, the air will contact the refrigerating plate 38, and the refrigerating plate 38 can reduce the temperature of the air, so that the heat dissipation effect of the energy storage tank 20 can be further improved. At the same time, the mesh plate 24 can filter the dust in the air to reduce the dust adhering to the inner wall of the conveying pipe 21 and the tank body 11 to affect the heat transfer. The gas will enter the inside of the conveying pipe 21 under the action of pressure, and the gas will flow upward in a spiral shape in the inside of the conveying pipe 21 to absorb the heat of the energy storage tank 20. Then, the cooling liquid is injected between the sealing plate one 19 and the sealing plate two 22 through the liquid inlet pipe 14. The cooling liquid will flow downward in a spiral shape outside the conveying pipe 21. In the process that the cooling liquid contacts the outer surface of the energy storage tank 20, the cooling liquid can absorb the heat of the energy storage tank 20. The reciprocating movement of the scraper 34 can scrape and clean the dust on the inner wall of the mesh plate 24. The working time of the mesh plate 24 can be prolonged to a certain extent, and the mesh plate 24 can always keep good transparency.
