Description

Technical Field

[0001] The utility model belongs to the technical field of the power supply safety of shipborne power systems, and particularly relates to a cooling device for a shipboard winch ROV umbilical cable. Background Art

[0002] With the increasing depth of human exploration in the ocean field, 3000-meter, 6000-meter, and 10000-meter-class deep-sea heavy-duty operation ROVs have emerged one after another. As an important link connecting the underwater ROV and the surface ship, the umbilical cable is an important medium for power and communication transmission. The umbilical cable is mainly retracted and released by a shipboard winch. When it works under live conditions, it generates heat. The underwater part can dissipate heat naturally through seawater, while the umbilical cable on the winch has its temperature rising rapidly or even exceeding the threshold due to multi-layer dense laying, seriously affecting the service life and operation reliability of the umbilical cable. Although the long-term operating allowable current carrying capacity considering the heat generation of the cable has been considered in the design and selection stage of the umbilical cable, the on-site conditions of most ships are harsh, and the high-temperature and sun-exposed environment seriously affects the heat dissipation ability of the umbilical cable.

[0003] In the prior art, Chinese invention patent application CN118243256A provides a temperature real-time detection and cooling device for an optoelectronic composite cable of a shipboard winch. This patent sets temperature sensors in all directions of the winch drum to detect the temperature of the umbilical cable in real time and uses a spraying system for cooling. However, the heat dissipation efficiency of only using water spraying for cooling is relatively low, and the effect is not ideal; moreover, the water spraying cooling method is not suitable for use in cold winters.

[0004] Therefore, how to provide an efficient cooling device for a shipboard winch ROV umbilical cable is an urgent technical problem to be solved at present. Content of the Utility Model

[0005] In view of the deficiencies in the prior art, the utility model provides a cooling device for a shipboard winch ROV umbilical cable. By forming a closed cavity in the cooling box and setting an air inlet and an air outlet to realize air circulation, and at the same time installing a nozzle for spraying cooling, the two cooling methods of air cooling and water cooling are combined, effectively improving the heat dissipation efficiency of the umbilical cable.

[0006] The utility model provides a cooling device for a shipboard winch ROV umbilical cable, including:

[0007] A cooling box, inside which a closed cavity for accommodating the winch is formed. Air inlets are opened on the left and right sides of the cooling box, and an air outlet is opened on the top of the cooling box. The air inlets and the air outlet are used for air circulation;

[0008] A nozzle, which is installed on the top of the cooling box, and the opening of the nozzle faces the umbilical cable wound around the winch.

[0009] This technical solution forms a closed cavity in the cooling box, sets an air inlet and an air outlet to achieve air circulation, and installs a spray head for spraying and cooling, combining the two cooling methods of air cooling and water cooling, effectively improving the heat dissipation efficiency of the umbilical cable.

[0010] In some embodiments, the marine winch ROV umbilical cable cooling device further includes a heat exchanger, which is installed at the air inlet and is used to cool the gas entering the cavity through the air inlet. Through the setting of the heat exchanger in this technical solution, the gas entering the cavity is effectively cooled, further improving the heat dissipation efficiency of the umbilical cable.

[0011] In some embodiments, the heat exchanger is connected to the shipboard chiller. The water inlet of the heat exchanger is connected to the cooling water outlet of the shipboard chiller, and the water return port of the heat exchanger is connected to the cooling water return port of the shipboard chiller. Through connecting the heat exchanger to the shipboard chiller in this technical solution, the existing resources of the shipboard chiller are utilized for cooling, achieving efficient cooling without large-scale transformation, and reducing additional energy consumption.

[0012] In some embodiments, the marine winch ROV umbilical cable cooling device further includes an exhaust fan, which is installed at the air outlet and is used to accelerate air circulation. Through the setting of the exhaust fan in this technical solution, the hot air is quickly discharged, further improving the cooling efficiency.

[0013] In some embodiments, the spray head is connected to the shipboard water supply system. Through connecting the spray head to the shipboard water supply system in this technical solution, there is no need to install an additional independent water source device, reducing the frequency of maintenance and water source replenishment, and continuous water supply can be achieved without large-scale transformation, with strong adaptability.

[0014] In some embodiments, there are multiple spray heads, and the multiple spray heads are evenly distributed on the top of the cooling box. Through setting multiple spray heads in this technical solution, the surface of the umbilical cable is evenly covered, providing a comprehensive cooling effect and avoiding local overheating.

[0015] In some embodiments, a drain pipe for draining water is provided at the bottom of the cooling box. Through the setting of the drain pipe in this technical solution, the wastewater generated during the cooling process is discharged in a timely manner, preventing water accumulation from affecting the operation of the equipment.

[0016] In some embodiments, at least two drain pipes are provided. Through increasing the number of drain pipes in this technical solution, the drainage is ensured to be unobstructed, further improving the reliability and operation efficiency of the cooling device.

[0017] In some embodiments, an air filter is further provided at the air inlet. Through the setting of the air filter in this technical solution, the air entering the cooling box is filtered to prevent dust and impurities from entering.

[0018] In some of these embodiments, a box door for opening the cavity is provided on the front side of the cooling box. Through the setting of the box door in this technical solution, it is convenient to inspect and maintain the interior of the cooling box.

[0019] Based on the above solution, the ROV umbilical cable cooling device for a marine winch in the embodiments of the present utility model forms a closed cavity in the cooling box, sets an air inlet and an air outlet to achieve air circulation, and installs a nozzle for spraying cooling at the same time, combining two cooling methods of air cooling and water cooling, effectively improving the heat dissipation efficiency of the umbilical cable and avoiding the influence of excessive temperature on the service life and operation reliability of the umbilical cable; and the air circulation is not limited by the ambient temperature and is applicable to various climate conditions, including the cold winter season; in addition, the ROV umbilical cable cooling device for a marine winch provided by the present utility model has a simple structure, is easy to manufacture and maintain, and reduces the complexity and cost of the equipment.
