[0001] The present invention mainly relates to the technical field of ship batteries, and particularly relates to a cooling system for a charging and discharging device for a ship. Background Art

[0002] In recent years, the types of ship energy batteries have gradually changed from being mainly based on fossil energy to low-carbon energy, and the trend of electrification has been increasing.

[0003] According to the in-box cooling device for ship batteries provided in the patent document with the application number CN202121072191.4, it can be known that the cooling device is composed of a cooling component and a heat exchange component used in cooperation with the cooling component. The beneficial effect of the in-box cooling device for ship batteries of this utility model is that it is reasonably designed, solves the heat dissipation problem of existing ship battery modules under high-rate charging and discharging conditions, helps the battery modules achieve higher charging and discharging rates, thus meeting the needs of users for fast charging and high-power discharging, promoting the rapid development of electric ships in various sub-fields, and has strong practicability.

[0004] The above-mentioned cooling device for ship batteries solves the heat dissipation problem of existing ship battery modules under high-rate charging and discharging conditions and helps the battery modules achieve higher charging and discharging rates. However, traditional ship batteries are difficult to adapt to tilting and swaying, and continuous tilting and swaying destroy the force balance in the normal static position, generating additional forces on moving parts, resulting in equipment failure or damage. Summary of the Invention

[0005] The present invention mainly provides a cooling system for a charging and discharging device for a ship to solve the technical problems raised in the above background art.

[0006] The technical solution adopted by the present invention to solve the above technical problems is as follows:[[]]

[0007] A cooling system for a charging and discharging device for a ship includes a storage battery, a balance mechanism is provided at the bottom end of the storage battery, and a cooling mechanism is provided outside the storage battery;

[0008] A bottom plate is installed on the lower surface of the storage battery, and pulleys are installed at the four corners of the lower surface of the bottom plate;

[0009] The cooling mechanism includes a cold row provided at one end of the storage battery and installed on the upper surface of the bottom plate, cold heads connected to the water outlet end of the cold row and installed on both side surfaces of the storage battery, and a universal water connection head installed on one side surface of the cold row;

[0010] The balance mechanism includes a sliding seat provided at the bottom end of the bottom plate, an arc-shaped slide rail provided inside the sliding seat for the pulley to slide, and two auxiliary support components provided between the two arc-shaped slide rails.

[0011] Furthermore, the two auxiliary support components are respectively located at both inner ends of the sliding seat. The auxiliary support component includes a plurality of first springs installed on the inner wall of the sliding seat, a support block installed on the upper surface of the first springs, and an auxiliary support wheel installed on the upper surface of the support block. In the present invention, the bottom plate is slid on the auxiliary support wheel to assist in supporting the bottom plate. Through the expansion and contraction of the first springs, the auxiliary support wheels thereon are pushed to keep in contact with the bottom plate, improving the stability of the auxiliary support wheels during support.

[0012] Furthermore, the auxiliary support component further includes a telescopic rod with one end installed on the lower surface of the support block and the other end installed on the inner wall surface of the sliding seat. In the present invention, the support block is guided to lift and lower linearly by the expansion and contraction of the telescopic rod, improving the stability of the auxiliary support wheel on the support block during support.

[0013] Furthermore, a buffer airbag is sleeved on the bottom end of the storage battery. An air inlet head and a high-pressure air release valve are installed on the shell of the buffer airbag. In the present invention, the inflated buffer airbag provides buffering for the storage battery. The buffer airbag intakes air through the air inlet head and releases air through the high-pressure air release valve.

[0014] Furthermore, an air pumping mechanism is connected between the two pulleys. The pulley includes a wheel seat installed on the lower surface of the bottom plate and a wheel body rotatably connected to the wheel seat through a rotating shaft.

[0015] Furthermore, the air pumping mechanism includes a sliding cylinder installed on the lower surface of the bottom plate, two air pumping cylinders installed inside the sliding cylinder, a push column provided at one end of the two air pumping cylinders away from each other and connected to one end of the rotating shaft extending into the sliding cylinder. The air outlet end of the air pumping cylinder is connected to the air inlet head through a pipe body. In the present invention, since the air outlet end of the air pumping cylinder is connected to the air inlet head through a pipeline, the gas generated by the air pumping cylinder enters the buffer airbag, causing the buffer airbag to expand.

[0016] Furthermore, the air pumping mechanism further includes two support pieces installed on the outer surface of the air pumping cylinder and a second spring provided between the two support pieces. In the present invention, through the expansion and contraction of the second spring, the support pieces are pushed back to their original working positions, and the piston rods of the air pumping cylinders are driven back to their original working positions by the support pieces.

[0017] Furthermore, the air outlet end of the high-pressure air release valve is connected to an air outlet pipe. A plurality of air outlet holes are provided on the shell of the air outlet pipe. In the present invention, the redundant gas in the buffer airbag is discharged through the air outlet pipe, and the air outlet pipe guides the airflow to blow towards the cold head through the air outlet holes thereon to self-clean the cold head.

[0018] Further, a semiconductor refrigerating sheet is provided inside the high-pressure air release valve. In the present invention, the semiconductor refrigerating sheet is used for refrigeration so that after the air outlet pipe blows out cold air, it can assist the cold head in cooling work.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] When the storage battery in the present invention sways following the course of the ship, by rolling the pulleys at the bottom of the storage battery on the arc-shaped slide rails, the center of gravity of the storage battery itself is adjusted, preventing the storage battery from being frequently affected by the ship's navigation, and thus preventing the additional force generated during navigation from damaging the storage battery, and preventing the concentration of the coolant in the cold row and the cold head, which may affect the cooling effect.
