Description

Technical Field

[0001] The present invention relates to the technical field of ship anti-sinking training, and in particular to a ship anti-sinking training device and a control method. Background Art

[0002] Anti-sinking skills are a fundamental skill for crew members. As a crucial component of their ability to handle flooding after a bulkhead breach, they are crucial to the safety of both the ship and the crew. Improving the anti-sinking capabilities of ship crews has become a matter of widespread concern.

[0003] Currently, anti-sinking training exercises all rely on water pumps, with variable speed controllers adjusting the pump speed to achieve varying water pressures. However, when pumps supply water, the required flow rate increases when the breach pressure is high and the number of breaches increases. However, there is an upper limit to the pump flow rate, resulting in a mismatch between the actual breach flow rate and pressure during training. Choosing a more powerful pump would be limited by the site's electrical power. Summary of the Invention

[0056] Figure 1 FIG. 1 is a schematic diagram of a ship anti-sinking training device according to an embodiment of the present invention. Figure 1 As shown, and reference Figures 2 to 5 An embodiment of the present invention provides a ship anti-sinking training device 100, comprising a training cabin 10, a water storage device 20, and an air source device 30. The training cabin 10 is provided with a breach. The water storage device 20 is connected to the breach via a connecting pipe. The air source device 30 is connected to the water storage device 20 to change the pressure within the water storage device 20 when supplying air to the water storage device 20.

[0057] In this embodiment, the ship anti-sinking training device 100 includes an air source device 30. The air source device 30 supplies air to the water storage device 20, increasing the pressure in the water storage device 20 as it supplies water to the training chamber 10. At the start of training, the water storage device 20 supplies water to the breach, simulating the flooding condition of a damaged ship bulkhead. During training, the amount of water in the water storage device 20 decreases, and the water pressure at the breach decreases. The air source device 30 supplies air to the water storage device 20 to increase the pressure therein, maintaining it constant. This maintains the pressure at the breach, making the simulated environment in the training chamber 10 more similar to actual conditions and improving the trainees' underwater damage control skills. Furthermore, the ship anti-sinking training device 100 is simple and easy for trainees to operate.

[0058] In some embodiments of the present invention, the shape of the training cabin 10 can be designed according to the specific ship type, so that the simulated environment in the training cabin 10 is closer to the actual situation, thereby improving the underwater damage control level of the trainees.

[0059] In some embodiments of the present invention, Figure 1 As shown, a second pressure reducing valve 620 is installed between the air source device 30 and the water storage device 20 .

[0060] In this embodiment, the second pressure-reducing valve 620 controls the flow rate of gas delivered from the gas source device 30 to the water storage device 20, thereby maintaining a constant water pressure at the breach. This ensures that the simulated environment within the training chamber 10 more closely resembles actual conditions. The second pressure-reducing valve 620 has a simple structure, allowing trainees to adjust the water pressure as needed, making it easy to operate.

[0061] In some embodiments of the present invention, Figure 1 As shown, the water storage device 20 includes a water storage tank 210 and a breached water tank 220. The water storage tank 210 has a first water outlet 230. The breached water tank 220 has a second water outlet 240, which is connected to the first water outlet 230 so that the water storage tank 210 supplies water to the breached water tank 220. The second water outlet 240 is connected to the breach so that the breached water tank 220 supplies water to the breach.

[0062] In this embodiment, the water storage tank 210 supplies water to the breach tank 220, which in turn supplies water to the breach in the training cabin 10. If the water in the breach tank 220 runs out, training can be suspended. The water storage tank 210 fills the breach tank 220 with water, and training can resume once the breach tank 220 is full. Replenishing the breach tank 220 with water from the water storage tank 210 prevents trainees from running out of water during training.

[0063] Furthermore, if the water storage device 20 includes only one breached water tank 220, water needs to be supplied to the breached water tank 220 by a water pump, and the pressure in the breached water tank 220 needs to be vented. Since the water storage device 20 includes the water storage tank 210 and the breached water tank 220, when replenishing water, the water storage tank 210 and the breached water tank 220 are connected, and the pressures in the water storage tank 210 and the breached water tank 220 are balanced, and the water storage tank 210 can supply water to the breached water tank 220 without venting the pressure in the breached water tank 220. This saves gas and time for replenishing the pressure in the breached water tank 220 after the breached water tank 220 is filled with water, thereby saving training time for trainees.

[0064] In some embodiments of the present invention, the water storage tank 210 and the breach water tank 220 are pressure vessels.

[0065] In this embodiment, the water tank 210 and the breached water tank 220 are capable of withstanding pressure, allowing the air source device 30 to provide airflow to the breached water tank 220, thereby increasing the pressure in the breached water tank 220 and maintaining the pressure of the water flow at the breach. When the water tank 210 fills the breached water tank 220 with water, both the water tank 210 and the breached water tank 220 are pressurized. Therefore, both the water tank 210 and the breached water tank 220 must be able to withstand pressure to maintain the normal operation of the ship anti-sinking training device 100.

[0066] In some embodiments of the present invention, the diameter of the water storage tank 210 is the same as the diameter of the breach water tank 220 , and the height of the water storage tank 210 is twice the height of the breach water tank 220 .

[0067] In this embodiment, the height of water storage tank 210 is twice the height of breached water tank 220, and the volume of water storage tank 210 is twice the volume of breached water tank 220. Under the action of gravity, water in water storage tank 210 flows into breached water tank 220. When the liquid level in water storage tank 210 and breached water tank 220 reaches equilibrium, breached water tank 220 is filled, and water in water storage tank 210 automatically stops flowing into breached water tank 220. By utilizing the height arrangement of water storage tank 210 and breached water tank 220, water is automatically poured into breached water tank 220 by gravity, and filling of breached water tank 220 automatically stops when breached water tank 220 is full. The ingenious arrangement of water storage tank 210 and breached water tank 220 facilitates water filling into breached water tank 220 without the need for a power device, thus saving energy and reducing consumption.

[0068] In some embodiments of the present invention, Figure 1 As shown, liquid level detection devices are installed on the top and bottom of the water storage tank 210. Liquid level detection devices are installed on the top and bottom of the breach water tank 220.

[0069] In this embodiment, a liquid level detection device is installed on the water tank 210 and the broken water tank 220. The water level in the water tank 210 and the broken water tank 220 is monitored by the liquid level detection device. When the water tank 210 and the broken water tank 220 are filled with water or empty, a prompt signal is issued, and the filling or emptying of water is stopped in time, thereby improving work efficiency.

[0070] In some embodiments of the present invention, the liquid level detection device is an ultrasonic liquid level meter.

[0071] In this embodiment, the ultrasonic level meter provides non-contact measurement without requiring direct contact with water, thus preventing water corrosion and reducing the need for replacement of the liquid level detection device. The ultrasonic level meter is simple and convenient to install, requiring no safety precautions. Furthermore, the ultrasonic level meter provides fixed-point, continuous measurement, continuously monitoring the liquid levels within the water storage tank 210 and the breached water tank 220.

[0072] In other embodiments of the present invention, the liquid level detection device is a float type liquid level gauge, a buoy type liquid level gauge or a differential pressure type liquid level gauge.

[0073] In some embodiments of the present invention, Figure 1 As shown, the breach includes a top breach 110 and a side breach 120. The second water outlet 240 is connected to the top breach 110 via a first connecting pipe 720. The second water outlet 240 is connected to the side breach 120 via a second connecting pipe 730.

[0074] In this embodiment, the training cabin 10 is provided with a top breach 110 and a side breach 120. The top breach 110 and the side breach 120 are controlled separately, allowing for anti-sinking and leak-proofing training to be conducted as needed, thereby meeting different anti-sinking and leak-proofing training requirements. For example, anti-sinking and leak-proofing training can be conducted for the top breach 110 alone, for the side breach 120 alone, or for both the top breach 110 and the side breach 120 simultaneously.

[0075] In some embodiments of the present invention, Figure 1 As shown, a pressure sensor 510 and a first pressure reducing valve 610 are provided at the breach. The first pressure reducing valve 610 is used to adjust the pressure of the water flow at the breach. The pressure sensor 510 is used to detect the pressure of the water flow at the breach.

[0076] In this embodiment, a pressure sensor 510 is installed at the breach. This sensor measures the pressure of the water flowing through the breach, thereby calculating the depth of the breach in the water. Adjusting the pressure-reducing valve at the breach allows the pressure of the water flowing through the breach to be varied, thereby changing the depth of the breach in the simulated environment. A first pressure-reducing valve 610 is used to simulate different environments in the training cabin 10, allowing trainees to adjust the valve to meet different anti-sinking and leak-proofing requirements.

[0077] In some embodiments of the present invention, the first pressure-reducing valve 610 is a pilot-operated adjustable pressure-reducing valve. The pilot-operated adjustable pressure-reducing valve has a stable outlet pressure. Therefore, the pressure of the water flowing out of the first pressure-reducing valve is relatively stable, that is, the pressure at the breach is relatively stable, making the simulated environment in the training cabin 10 more similar to the actual environment, thereby improving the underwater damage control skills of the trainees.

[0078] The present invention also provides a control method for the ship anti-sinking training device 100, such as Figure 1 and Figure 2 As shown, the ship anti-sinking training device 100 includes a training cabin 10, a water storage tank 210, a breach water tank 220, and an air source device 30. The training cabin 10 is provided with a top breach 110 and a side breach 120. A pressure sensor 510 and a first pressure reducing valve 610 are installed at the top breach 110 and the side breach 120. The water storage tank 210 is connected to a water source 80. The breach water tank 220 is connected to the water storage tank 210, supplying water to the breach water tank 220. The breach water tank 220 is connected to the top breach 110 and the side breach 120. A first electric ball valve 630 is installed between the breach water tank 220 and the top breach 110. A second electric ball valve 640 is installed between the breach water tank 220 and the side breach 120. The air source device 30 is connected to the breach water tank 220 to change the pressure in the breach water tank 220 ; a second pressure reducing valve 620 and a first solenoid valve 650 are provided between the breach water tank 220 and the air source device 30 .

[0079] Control methods include:

[0080] In step S110 , the water storage tank 210 and the breach water tank 220 are filled with water, the second pressure reducing valve 620 is adjusted, and the first solenoid valve 650 is opened to make the pressure in the breach water tank 220 reach a first preset pressure.

[0081] Step S120 , regulating the first pressure reducing valve 610 so that the water flow pressure at the top breach 110 and / or the side breach 120 reaches a second preset pressure.

[0082] Step S130: Open the first electric ball valve 630 and / or the second electric ball valve 640 to start training.

[0083] In this embodiment, the ship anti-sinking training device 100 includes a training cabin 10, a water storage tank 210, a breach tank 220, and an air source device 30. The training cabin 10 is provided with a top breach 110 and a side breach 120. The water storage tank 210 supplies water to the breach tank 220, and water flows from the breach tank 220 to the top breach 110 and the side breach 120. Trainees train within the training cabin 10. During training, the first solenoid valve 650 is opened, and the air source device 30 provides pressure to the breach tank 220. The pressure in the breach tank 220 is adjusted by regulating the second pressure reducing valve 620, so that the pressure in the breach tank 220 reaches a first preset pressure. The first pressure-reducing valve 610 is adjusted so that the water flow at the top breach 110 and the side breach 120 maintains the second preset pressure. After the first electric ball valve 630 and / or the second electric ball valve 640 are opened, the water flows to the top breach 110 or the side breach 120, and the trainee begins training. Because the first pressure-reducing valve 610 is always in the open state, when the water level in the breach water tank 220 drops, the air source device 30 continuously supplies air to the breach water tank 220 to maintain the first preset pressure in the breach water tank 220 and the second preset pressure in the top breach 110 and the side breach 120. The control method of the ship anti-sinking training device 100 is simple. During the training process, the first pressure-reducing valve 610 can be kept in the open state. The operation is convenient and easy for the trainee to operate.

[0084] When the first electric ball valve 630 is opened, anti-sinking and leak-proofing training is conducted on the top breach 110. When the second electric ball valve 640 is opened, anti-sinking and leak-proofing training is conducted on the side breach 120. When the first and second electric ball valves 630, 640 are opened, anti-sinking and leak-proofing training is conducted on both the top breach 110 and the side breach 120 simultaneously.

[0085] In some embodiments of the present invention, the pressure of the air source device 30 is greater than a first preset pressure, which is greater than a second preset pressure. Due to the pressure difference between the air source device 30, the breach water tank 220, the top breach 110, and the side breach 120, gas can flow from the air source device 30 to the breach water tank 220, and water can flow from the breach water tank 220 to the top breach 110 and the side breach 120.

[0086] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the top of the water storage tank 210 and the top of the breached water tank 220 are connected by an exhaust pipe 710, which is equipped with a second solenoid valve 660. The height of the water storage tank 210 is twice that of the breached water tank 220, and the diameter of the water storage tank 210 is the same as that of the breached water tank 220. The breached water tank 220 is equipped with a first low liquid level detection device 430 and a first high liquid level detection device 410.

[0087] The control method also includes:

[0088] Step S210: When the first low liquid level detection device 430 of the broken water tank 220 detects that the liquid level of the broken water tank 220 is about to reach a low water level, the first electric ball valve 630 and / or the second electric ball valve 640 are closed and the training is suspended.

[0089] In step S220 , the first solenoid valve 650 is closed, and the second solenoid valve 660 is opened. The pressures in the water storage tank 210 and the breached water tank 220 are balanced, and water is injected from the water storage tank 210 into the breached water tank 220 .

[0090] Step S230 , when the first high liquid level detection device 410 of the breach water tank 220 detects that the water level in the breach water tank 220 has reached the high water level, the injection of water into the breach water tank 220 is stopped.

[0091] In step S240, the second solenoid valve 660 is closed, and the first solenoid valve 650 is opened. When the pressure in the breach water tank 220 reaches the first preset pressure, the training continues.

[0092] In this embodiment, when the water level in the breach water tank 220 is insufficient, water is supplied to the breach water tank 220 via the water storage tank 210. When the liquid level in the breach water tank 220 reaches a low level, training is suspended. The first solenoid valve 650 is closed, and the air source device 30 stops supplying air to the breach water tank 220. The second solenoid valve 660 is opened, and air in the breach water tank 220 flows into the water storage tank 210 until the pressures in the breach water tank 220 and the water storage tank 210 are balanced. Under the action of gravity, water from the water storage tank 210 flows into the breach water tank 220. When the liquid level in the breach water tank 220 reaches a high level, water injection is stopped. The second solenoid valve 660 is closed, and the first solenoid valve 650 is opened to re-pressurize the breach water tank 220. When the pressure reaches the first preset pressure, the first electric ball valve 630 and / or the second electric ball valve 640 are opened, and training is resumed. The control method also includes a water replenishment method for the breach water tank 220. The water replenishment method is simple, convenient for training personnel to operate, and improves the efficiency of anti-sinking and leak-blocking training.

[0093] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, a second high liquid level detection device 420 is installed on the water storage tank 210. A third electric ball valve 670 is provided between the water storage tank 210 and the water source 80.

[0094] The control method also includes:

[0095] In step S310 , the pressure in the water storage tank 210 is exhausted.

[0096] Step S320 , opening the third electric ball valve 670 to inject water into the water tank 210 .

[0097] Step S330: When the second high liquid level detection device 420 detects that the water level in the water tank 210 reaches the high water level, the filling of water into the water tank 210 is stopped.

[0098] Step S340: close the third electric ball valve 670.

[0099] In this embodiment, after the water tank 210 has completed its water replenishment into the breached water tank 220, pressure builds up in the water tank 210. After the pressure is vented, water is replenished into the water tank 210. The control method also includes a method for replenishing the water tank 210. After the breached water tank 220 is fully filled, the trainees can replenish the water tank 210 while they are training, thus saving their training time and improving the efficiency of the anti-sinking and leak-proofing training.

[0100] In some embodiments of the present invention, Figure 1 and Figure 5 As shown, a second low liquid level detection device 440 is also installed on the water tank 210.

[0101] The control method also includes:

[0102] Step S410, after the training is finished, the first solenoid valve 650 is closed, and the second solenoid valve 660 is opened, so that the pressure in the water storage tank 210 and the breach water tank 220 is balanced.

[0103] Step S420: drain the water in the water storage tank 210.

[0104] In step S430 , when the second low liquid level detection device 440 detects that the water level in the water storage tank 210 is at a low water level, the water in the breached water tank 220 is drained.

[0105] In this embodiment, after training, the first solenoid valve 650 is closed and the second solenoid valve 660 is opened to equalize the pressure in the water tank 210 and the breached water tank 220. The water in the water tank 210 is drained, followed by the water in the breached water tank 220. All valves are reset. This draining of the water in the water tank 210 and the breached water tank 220 prevents bacterial growth in the water tank 210 and the breached water tank 220, which could affect the health of the trainees.

[0106] In other embodiments of the present invention, the water in the water storage tank 210 and the breach water tank 220 may not be emptied and may be used in the next training session.

[0107] At this point, those skilled in the art will recognize that, although a number of exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications consistent with the principles of the present invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
