Description

Technical Field

[0001] The invention relates to the technical field of ship antifreezing, and in particular to a floating antifreezing device for a side liquid tank and a use method thereof. Background Art

[0002] When a ship is sailing or operating in a low-temperature environment, the ballast water on the inner surface of the ballast tank may freeze, causing the ballast tank to be unable to withstand the closed air pressure generated by the transfer, which is likely to cause the ballast tank hull structure to deform or even burst, damaging the hull structure, affecting the safety of the ship and the lives of personnel. The ballast tank is an important part of the ship's ballast water system and is also the most typical side liquid tank. Therefore, for ships sailing or operating in ice areas, they usually face the challenge of cold protection from low temperatures outside. The antifreeze of the side liquid tank is even more important, which will directly affect the draft adjustment and structural safety of the ship.

[0003] The volume of the ship's side tank is very large, so the demand for cold-proof heat sources is huge. Conventional coil heating requires a long coil length and a large amount of steam, and long-term immersion in water has specific requirements for pipe materials and fluid media. In order to cover a large area of ​​cold-proof area with coils, its layout is also difficult and the cost is greatly increased. At the same time, the boiler size and heat source load of polar ships are relatively tight, and the antifreeze of the side tank is the main user of steam. If the steam consumption can be optimized or reduced, it will be of significant help to the ship design. In addition, except for the vent area, the other parts of the side tank are relatively closed and loaded with a large amount of seawater. It is impossible for operating personnel to reach it, and it is currently impossible to directly observe the situation in the cabin. In order to study the freezing process of the tank and understand the impact of the free surface of the tank on the navigation of the ship, it is also necessary to monitor the cabin in real time to promote the development of intelligent polar equipment for ships.

Then, the float heating device body rises with the liquid level, passes through the air pipe protection sleeve pipeline, and docks and locks with the receiving seating mechanism. Then, the first power supply system is connected to the float heating device body to complete the recovery of the float heating device body.

[0049] The receiving and seating mechanism 140 is sleeved on the air-permeable tube structure 110 and is used to connect the float heating device body F200.

[0050] In a further embodiment, referring to Figure 2 The ventilation pipe structure 110 includes a ventilation main body pipeline 111 and a protective sleeve pipeline 112. The protective sleeve pipeline 112 is arranged in the side liquid tank 1 for arranging the relevant lines of the first power supply system 120 and the first cold protection system 130, and the upper end thereof extends out of the cabin top to optimize the ventilation effect. The ventilation main body pipeline 111 is connected to the upper end of the protective sleeve pipeline 112.

The protective sleeve ventilation structure 113 is close to the top of the side liquid tank 1, and cooperates with the structural design that the top of the protective sleeve pipeline 112 is higher than the top of the tank to ensure the ventilation effect of the side liquid tank 1 when the water level is full, avoiding suffocation in the cabin. When the liquid level in the cabin is lower than the bottom of the protective sleeve pipeline 112, the bottom surface and the inside of the pipeline can also be ventilated in the cabin.

[0051] In a further embodiment, the float heating device body F200 is hollowed out and has a two-layer structure of an inner ring and an outer ring, including:

[0052] The docking fixing mechanism 210 is arranged on the inner wall of the float heating device body F200, and is matched and connected with the receiving and seating mechanism 140, and is used for the detachable connection between the float heating device body F200 and the air-permeable tube base device V100;

[0053] The energy absorption and utilization mechanism 220 includes an internal mechanism 221 and a tentacle mechanism 222. The internal mechanism 221 is located between the inner ring and the outer ring of the float heating device body F200. The internal mechanism 221 is connected to the tentacle mechanism 222 and is used to absorb the kinetic energy and potential energy generated by the float heating device body F200 as the liquid surface moves. A plurality of tentacle mechanisms 222 are evenly arranged on the outer wall of the float heating device body F200, mainly to assist in absorbing the wave energy of the liquid surface and the mechanical energy of its own movement. At the same time, after being energized, the tentacle mechanism 222 can also be used to assist in cold-proof heating, realize the autonomous movement of the float heating device body F200 and escape from narrow structural areas.

[0054] The anti-overturning mechanism 230 is used to stabilize the posture of the float heating device body F200. Regardless of the change of the liquid level or the change of the ship's posture, the float heating device body F200 in the liquid level release state can be suspended on the free liquid surface, and has anti-overturning and posture recovery capabilities to maintain the floating posture. Its use is not limited to structures such as anchoring systems;

[0055] The second power supply system 240 is used for supplying power to the float heating device body F200 and storing the electric energy converted by the energy absorption and utilization mechanism 220;

[0056] The signal transmission system 250 is used to transmit the data collected by the positioning system 260 to the ship monitoring and control system, and transmit the command signal of the ship monitoring and control system to the float heating device body F200, so that the float heating device body F200 can perform the task. The data of each system includes but is not limited to: spatial ranging, liquid level, temperature, posture, ice accumulation degree, power consumption, and power storage; the operation instructions include but are not limited to: energy absorption, heating, ice breaking, positioning, power supply and mode selection, movement and mode selection, etc.

[0057] The second cold protection system 270 includes an electric heating mechanism 271 and a side ice breaking mechanism 272. The electric heating mechanism 271 is used to perform adaptive heat release and cold protection according to the ice accumulation degree and temperature detected by the positioning system 260. The heat release degree can be automatically adjusted according to the different ice accumulation degrees measured, and a large range of auxiliary heating can also be performed through the tentacles 222. The side ice breaking mechanism 272 is distributed on the outer side wall of the outer ring of the float heating device body F200. The thinner ice can be destroyed by the self-movement of the float heating device body F200, and the thicker ice can also be driven by the electric energy output by the second power supply system 240;

[0058] The mobile system 280 includes an autonomous module 281 and a traction module 282, which are used for autonomous movement, traction movement and passive movement of the float heating device body F200. The autonomous module 281 is mainly powered by the self-power supply module 241. According to the sensing distance data of the positioning system 260, the autonomous movement is achieved through the rotation of the float heating device body F200 and the movement of the tentacle mechanism 222. The traction module 282 stops the autonomous movement and follows the control of the bulkhead fixing device G300 to achieve traction movement. The passive movement is to go with the flow, that is, passive movement is performed under the action of liquid surface waves, and it is converted into active movement when a collision is about to occur.

[0059] Specifically, the float heating device body F200 has two states: base fixed and liquid level released. After the liquid level drops, the body can be released to always float on the free liquid surface and move freely in the cabin (active / passive), and the wave kinetic energy / potential energy of the free liquid surface is converted into electrical energy for storage or use, so as to achieve heating of the liquid surface at the location, ensure that the inner and outer circle areas will not be frozen, and ensure the ventilation of the cabin. There are two forms of active movement: autonomous movement and cable traction, and passive movement is drifting with the waves.

[0060] In a further embodiment, the second power supply system 240 includes a self-powered module 241, an energy storage charging module 242, and a second external power supply module 243. The self-powered module 241 is connected to the energy storage charging module 242, and the energy storage charging module 242 is connected to the energy absorption and utilization mechanism 220. The self-powered module 241 mainly obtains electric energy from the energy storage charging module 242 when the float heating device body F200 is in a liquid level release state, and is used to provide power for the docking fixing mechanism 210, the autonomous module 281, the positioning system 260, and the second cold protection system 270. The second external power supply module 243 is connected to the energy storage charging module 242. The charging module 242 is connected, the second external power supply module 243 is connected to the first external power supply module 121, the energy storage charging module 242 can be directly powered by the energy absorption and utilization mechanism 220, and can also be charged from the second external power supply module 243 when the float heating device body F200 is in a fixed state on the base. When the float heating device body F200 is seated and locked on the air vent base device V100, the second external power supply module 243 located on the float heating device body F200 is connected to the first external power supply module 121 to supply power to the system required by the float heating device body F200.

[0061] In a further embodiment, the positioning system 260 includes a sensing mechanism 261 and an intelligent data processing module 262. The sensing mechanism 261 is used for spatial distance measurement and collects data such as liquid level, temperature and ice accumulation. The intelligent data processing module 262 processes and analyzes the data collected by the sensing mechanism 261 to a certain extent to achieve real-time positioning and autonomous adjustment of the operating status (attitude, heating amount, ice breaking degree, etc.), and sends the processed data to the signal transmission system 250 and feeds back to the ship monitoring and control system.

[0062] In a further embodiment, referring to Figure 3 , Bulkhead Fixing Device G300 also includes:

The disengagement free retractable mechanism 320 is fixed to the inner wall of the side tank 1 and connected to the float heating device body F200 through a cable, and cooperates with the autonomous module 281 to achieve the autonomous movement of the float heating device body F200 and perform cable retractable operation;

[0064] The wave making system 330 is arranged at the bottom of the inner wall of the side tank 1 and is connected to the source system such as compressed air. According to the operation state of the float heating device body F200 and the degree of electric energy conversion of the energy absorption and utilization mechanism 220, the wave making system 330 actively intervenes in the movement degree of the free liquid surface by adjusting the inflow of the air source (not limited to air, but also other fluid media) to achieve energy control;

[0065] The third cold protection system 340 is connected to an external heat source and is used for heating and deicing the active cable retracting and releasing mechanism 310 , the disengaging free retracting and releasing mechanism 320 , and the wave-making system 330 .

The active cable retracting and releasing mechanism 310 is connected to the traction module 282, and includes a single-point action module 311 and a three-point coordinated action module 312. The single-point action module 311 is used for unidirectional pulling, and the three-point coordinated action module 312 is used for multi-point simultaneous action. By pulling and releasing the cable, movement to any position in the space is realized.

The wave-making system 330 is connected to the source system such as compressed air, which can control the switch and flow rate; the cold protection system heats the area near the fixed point by providing an external heat source to avoid ice.

[0068] For the use of floating antifreeze device for side tanks, refer to Figure 4 , including the following steps:

[0069] S01, in the initial state, the side liquid tank 1 is fully loaded (liquid level 1) or empty (liquid level 2), there is basically no free liquid surface, and the available energy is extremely low. The float heating device body F200 is in the base fixed state, located at the beginning\end position in the figure, and is connected to the ventilating tube base device V100 through the docking fixing mechanism 210. At this time, the first external power supply module 121 and the second power supply module 243 charge the float heating device body F200, and the first cold protection system 130 performs cold protection heating on the ventilating tube structure 110 area. The second cold protection system 270, the second power supply system 240, the docking fixing mechanism 210, etc. of the float heating device body F200 are all powered by the first external power supply module 121 and the second external power supply module 243, and cooperate with the first cold protection system 130 to perform cold protection heating on the ventilating tube area;

[0070] S02, the liquid level in the side liquid tank 1 changes, the side liquid tank 1 is in a half-loaded state, the connection between the first power supply system 120 and the float heating device body F200 is disconnected, and a release command is issued to control the receiving seat mechanism 140 and the docking fixing mechanism 210 to change from a locked state to a released state, and the float heating device body F200 falls freely along the protective sleeve pipeline 112 under the action of gravity to reach the liquid surface below the air permeable pipe structure 110, that is, the preparation position. In this process, the free retractable mechanism 320 is disconnected, and the cable has no traction force, which is a follow-up motion;

[0071] S03, the float heating device body F200 enters the liquid level release state, leaves the preparation position, and enters the working position. The power supply of the float heating device body F200 is provided by the self-power supply module 241 and the energy storage charging module 242. The energy absorption and utilization mechanism 220 starts to operate and continuously replenishes power for the energy storage charging module 242.

[0072] Specifically, in the preparation position, the float heating device body F200 enters the liquid surface release state. At this time, the first cold protection system 130 is always powered by the first external power supply module 121 to keep running to prevent the air permeable pipe structure 110 from freezing. The power supply of the float heating device body F200 is provided by the self-power supply module 241 and the energy storage charging module 242. The energy absorption and utilization mechanism 220 starts to operate and continuously replenishes power for the energy storage charging module 242. In this state, there are three movement modes: one is passive drifting; the other two are active movement, which are respectively executed by the autonomous module 281 of the body and the traction module 282 controlled by the bulkhead fixing device G300, leaving the preparation position and entering the working position;

[0073] S04. After being in the operating position, the second cold protection system 270 of the float heating device body F200 enables the float heating device body (F200) to move autonomously through the autonomous module (281), or to move under the traction of the bulkhead fixing device (G300), or to move passively under the action of the liquid surface waves, according to the real-time data fed back by the positioning system 260, and provides sufficient heat and ice-breaking power to ensure that a dense ice layer is not formed on the free liquid surface, and controls the float heating device body F200 area to have sufficient air permeability; this also requires the energy absorption and utilization mechanism 220 can continuously replenish sufficient electric energy, and the free liquid surface has sufficient wave energy. If it is detected that the converted electric energy is insufficient, the wave-making system 330 will be started, and the regulating medium such as the air source will be introduced to adjust the movement degree of the free liquid surface and change the energy absorption effect; in addition, the anti-overturning mechanism 230 can ensure a stable floating posture; when the float heating device body F200 moves to the boundary, the tentacle mechanism 222 can effectively avoid collision with the bulkhead wall; and the active cable retracting mechanism 310 and the traction module 282 can effectively escape when their own energy is insufficient or trapped in a narrow area;

[0074] S05. When the cold-proof task is completed and the liquid level in the side tank 1 is about to reach the lower end of the air-permeable pipe structure 110 or the float heater body F200 is insufficient in energy, the float heater body F200 is recovered, and the float heater body F200 at any position is towed and moved to the bottom of the air-permeable pipe structure 110 by the towing module 282 and the three-point coordinated action module 312, and aligned, that is, returned to the preparatory position. This step must be completed before the liquid level reaches the bottom of the air-permeable pipe structure 110, and when the liquid level reaches the protective sleeve After reaching the lower end of the pipeline 112, ventilation in the cabin is achieved through the protective sleeve ventilation structure 113, and then the float heating device body F200 rises with the liquid level. After the central hollow area is docked with the protective sleeve pipeline 112, it will continue to rise along the protective sleeve pipeline 112, and directly reach the receiving seating mechanism 140. After being interlocked and fastened by the docking and fixing mechanism 210, it enters the base fixing state. At this time, the first power supply system 120 is connected to the power supply system of the float heating device body F200 to complete the recovery of the float heating device body F200.
