[0030] Please refer to Figure 7 , Figure 7 A schematic diagram of a central control unit structure of an integrated broken pipe training device provided by an embodiment of the present application.

[0031] Please refer to Figure 1 , the embodiment provides an integrated broken pipe training device, which comprises a water supply unit 100, a water immersion unit 200 and a water drainage unit 300 which are sequentially communicated to form a closed-loop water circulation loop. The device realizes the whole-process training function from broken pipe water inlet simulation to water accumulation removal through the organic integration of the three units.

[0032] The structure of the water supply unit 100 can comprise: As shown in Figure 2 , the water supply unit 100 comprises a water pool 102, a circulating water pump, a heating device 103 and a purification device 104. The water pool 102 serves as a water source storage device of the whole system, and the volume is set according to the training scale. In the embodiment, the volume of the water pool is 50 cubic meters.

[0033] As shown in Figure 5 , the circulating water pump is realized by using a water pump branch 101, which comprises a variable frequency pump group composed of three centrifugal pumps 401 connected in parallel. The suction line of each centrifugal pump 401 is connected to the bottom of the water pool 102 through an independent water suction pipeline, and an electric valve 402, a filter 403, a vacuum gauge 404 and a damping pipe 405 are sequentially installed on the suction line. The discharge line of each centrifugal pump 401 is sequentially provided with a damping pipe 405, a manual regulating valve 406, an electric valve 407 and a pressure gauge 408. The discharge lines of the three centrifugal pumps 401 are connected to a water supply header 409, which is a water supply main pipe. The water supply header 409 is provided with a pressure sensor 410, a gas release valve 411 and a pressure gauge 412.

[0034] Further, the water supply header 409 is provided with a discharge branch 105. The discharge branch 105 includes, in series, a stop valve 413, a pressure maintaining valve 414, a discharge filter 415, and a stop valve 416, and is connected to the water pool 102 through a pipeline. The discharge branch 105 is further provided with a bypass valve 417 which is connected in parallel with the stop valve 413, the pressure maintaining valve 414, the discharge filter 415, and the stop valve 416. The pressure maintaining valve 414 is used to maintain the pressure of the water supply header 409 constant, and automatically opens the discharge when the pressure of the water supply header 409 exceeds a set value. The bypass valve 417 is used to manually discharge when the pressure maintaining valve 414 fails.

[0035] The heating device 103 is arranged inside the water pool 102 and adopts a plate heat exchanger structure. The plate heat exchanger is connected to a site boiler heat source through a heat source interface, and is connected with a temperature controller. The temperature controller monitors the water temperature of the water pool 102 in real time, and controls the heat source supply valve to open when the water temperature is lower than a set value, so as to heat the water in the water pool 102 to meet the needs of different training environments.

[0036] The purification device 104 is arranged outside the water pool 102 at the top side. The purification device 104 includes a self-priming pump and a multi-stage filter. The suction inlet of the self-priming pump is connected to the water pool 102 through a pipeline, and the self-priming pump pumps the returned water after training in the water pool 102 to the multi-stage filter. The multi-stage filter adopts a combination of physical filtration and chemical purification, and is used to filter impurities such as particulate matter, waste gas, and waste oil. The clean water filtered by the multi-stage filter is returned to the water pool 102 by gravity flow, so as to realize the cyclic purification of water quality.

[0037] The water supply unit 100 is further provided with a water replenishment branch 106 which is connected to a municipal water supply network and is used to replenish the water loss of the system during operation. The returned water pipeline 108 is connected to the water pool 102 and is used to receive the training water discharged by the water drainage unit 300.

[0038] The structure of the water immersion unit 200 can include: As shown in Figure 3 The water immersion unit 200 includes, in series, a gate valve 201, a pressure sensor 203, a flow meter 202, a flow regulating valve 204, and a buffer tank 205 on the water supply branch 107 connected to the water supply header 409.

[0039] The gate valve 201 is a manual valve installed at the water inlet end of the water immersion unit 200 and serves as a total switch of the water source of the training area. Before the training starts, the commander manually opens the gate valve 201; and in the case of training end or emergency, the water source is quickly cut off by closing the gate valve 201.

[0040] The pressure sensor 203 is installed downstream of the gate valve 201 to monitor the pressure of the water supply pipeline in real time and transmit the pressure data to the central control unit. The flow meter 202 is installed downstream of the pressure sensor 203 to monitor the water flow to the buffer tank 205 in real time and transmit the flow data to the central control unit.

[0041] The flow regulating valve 204 is an electric regulating valve installed downstream of the flow meter 202. The flow regulating valve 204 receives control signals from the central control unit to control the water flow to the buffer tank 205 by precisely adjusting the valve opening, thereby simulating different water inflow rates from fine leakage to large breaches.

[0042] As shown in Figure 6 , the buffer tank 205 is a cubic structure made of stainless steel plate welding. The buffer tank 205 is provided with a water inlet flange 205-1, a hand hole 205-3 and a drain valve 205-2. The water inlet flange 205-1 is connected to the outlet of the flow regulating valve 204 to receive training water from the water supply unit 100. The hand hole 205-3 is provided at the top of the buffer tank 205 for maintenance and cleaning of the inside of the buffer tank 205. The drain valve 205-2 is provided at the bottom of the buffer tank 205 to drain the accumulated water in the buffer tank 205 after the training is completed.

[0043] The buffer tank 205 is fixedly installed on the cabin wall or cabin bottom of the training cabin by welding or bolt connection. The buffer tank 205 is provided with a breach panel 205-4 communicating with the inside of the training cabin. The breach panel 205-4 is designed in a modular and detachable manner and is installed on the side of the buffer tank 205 facing the training cabin through a sealing gasket and fasteners. The breach panel 205-4 is flush with the inner surface of the cabin wall or cabin bottom of the training cabin, ensuring the authenticity of the training environment.

[0044] The breach panel 205-4 is provided with at least one simulated breach. According to different training needs, different types of breach panels 205-4 can be replaced. The simulated breaches on different breach panels 205-4 have different sizes or shapes, such as circular breaches, irregular breaches, narrow cracks, etc., with a breach diameter ranging from 10 mm to 300 mm. During training, the water in the buffer tank 205 rushes into the training cabin through the simulated breaches on the breach panel 205-4, realistically reproducing the scene of water inflow due to ship damage.

[0045] The structure of the water drainage unit 300 can include: As shown in Figure 4 , the water drainage unit 300 includes a floor drain 301, an electric valve 302, a mobile submersible pump 308 and a jet pump 303.

[0046] The floor drains 301 are distributed in different deck positions of the training cabin for collecting the overflow water in the training cabin. The outlets of the floor drains 301 are connected to the return water line 108 through a pipe after being collected by the pipe. The electric valve 302 is controlled by the central control unit and can be opened and closed automatically or manually to control the gravity drainage. The collected water flows back to the pool 102 through the return water line 108 by gravity.

[0047] The mobile submersible pump 308 is arranged in the sump of the training cabin. When the gravity drainage is insufficient due to the deep water in the training cabin, the mobile submersible pump 308 is started to perform forced drainage. The mobile submersible pump 308 is connected to the return water line 108 through the quick connector 309, which facilitates the quick installation and disassembly of the submersible pump. The return water line 108 is provided with a one-way valve 310 to prevent backflow. The water discharged by the mobile submersible pump 308 is discharged back to the pool 102 through the return water line 108.

[0048] The power port of the jet pump 303 is connected to the power water source 307 through a pipe. The power water source 307 is a high-pressure water source, and the pressure of the power water source 307 in this embodiment is 0.4-0.6 MPa. The jet pump 303 uses the high-pressure power water source to generate negative pressure to suck the water in the training cabin. The suction port of the jet pump 303 is provided with a filter 306 and an inlet butterfly valve 305. The filter 306 is used to filter large particles to prevent the jet pump 303 from being blocked. The inlet butterfly valve 305 is used to control the start and stop of the jet pump 303. The discharge port of the jet pump 303 is connected to the return water line 108 through an outlet butterfly valve 304. The water discharged by the jet pump 303 is discharged back to the pool 102 through the return water line 108.

[0049] The central control unit can include: As shown in Figure 7 The embodiment also includes a central control unit. The central control unit is signal connected with the centrifugal pump 401 of the circulating water pump, the temperature controller of the heating device 103, the purification device 104, the pressure sensor 410 on the water supply header 409, the flow meter 202, the pressure sensor 203, the flow regulating valve 204 of the immersion unit 200 and the electric valve 302 of the drainage unit 300 through signal lines.

[0050] The central control unit adopts a control system composed of an industrial computer and a PLC controller. The central control unit has a human-machine interface, and a training commander sets training parameters through the interface, including the opening size, water supply pressure, and training time. The central control unit controls the flow regulating valve 204 and the centrifugal pump 401 in a closed loop according to the feedback signals of the pressure sensors 203 and 410 and the flow meter 202, so as to maintain the set water supply pressure and flow. The central control unit also monitors and records the pressure, flow, water level, training time and other data in real time during the training, and automatically generates a training report after the training, providing a quantitative basis for training evaluation.

[0051] Further, the workflow of the embodiment can include: Before the training starts, the pool 102 is filled with water, the purification device 104 purifies the water quality, and the heating device 103 heats the water to the set temperature according to the training requirements. The centrifugal pump 401 is started, the water supply header 409 is filled with water and pressure is established, and the pressure maintaining valve 414 in the discharge branch 105 is automatically adjusted to maintain the constant pressure of the water supply header 409.

[0052] The training commander sets the opening size, water inflow and water supply pressure and other parameters of this training through the central control unit. After the training personnel enter the training cabin and take their positions, the commander manually opens the gate valve 201, and at the same time the central control unit controls the flow regulating valve 204 to open to the set opening degree. The water from the water supply header 409 enters the buffer tank 205 through the flow regulating valve 204, and then rushes into the training cabin through the simulated opening on the opening panel 205-4, simulating the water inflow scene of the ship body damage.

[0053] The training personnel select appropriate plugging materials to plug the opening according to the opening position and water inflow. At the same time, the accumulated water in the training cabin is collected through the floor drain 301, and flows back to the pool 102 through the electric valve 302 and the return water pipeline 108. When the accumulated water is deep, the training personnel start the mobile submersible pump 308 or the jet pump 303 to force drainage, and the discharged water also flows back to the pool 102 through the return water pipeline 108, forming a closed loop water circulation.

[0054] During the training, the central control unit monitors the water supply pressure, flow and other parameters in real time, and automatically adjusts the flow regulating valve 204 and the centrifugal pump 401 according to the feedback signals to ensure the stability of the training conditions. After the training is completed, the commander closes the gate valve 201 and the flow regulating valve 204 to stop water supply. The drain valve 205-2 is opened to empty the buffer tank 205, and the electric valve 302 is opened to empty the accumulated water in the training cabin. The central control unit generates a data report of this training, including the plugging time, drainage rate, cabin water level change and other data, which provides a basis for training effect evaluation.

[0055] The embodiment realizes full-process simulation of the broken pipe training, training water recycling, water resource saving, realistic and safe and controllable training scene, and quantifiable evaluation of training effect through the organic integration of the water supply unit 100, the water immersion unit 200 and the water drainage unit 300.

[0056] Further, the application also provides a specific embodiment.

[0057] The embodiment optimizes the configuration of the water supply unit 100 and the water immersion unit 200 on the basis of the first embodiment to meet the training requirement of higher intensity.

[0058] In the embodiment, the frequency conversion pump group of the circulating water pump is increased from three centrifugal pumps 401 to five centrifugal pumps 401 in parallel, and the rated flow of a single centrifugal pump 401 is 80 cubic meters per hour, and the head is 50 meters. The five centrifugal pumps 401 can be flexibly combined and operated according to the training requirement, and the maximum water supply flow can reach 400 cubic meters per hour, which can simultaneously meet the water supply requirement of multiple training cabins.

[0059] In the relief branch 105, the set pressure of the pressure holding valve 414 is 0.5 MPa. When the pressure of the water supply header 409 exceeds 0.5 MPa, the pressure holding valve 414 automatically opens the relief to drain the excess water back to the water pool 102 through the relief filter 415, thereby ensuring the stability of the water supply pressure. At the same time, a safety valve is additionally arranged on the water supply header 409, which automatically opens the pressure relief when the pressure exceeds 0.7 MPa, thereby ensuring the safety of the system.

[0060] The heating device 103 adopts a double-circuit plate heat exchanger, which is configured with two plate heat exchangers operating in parallel. The heat exchange power of each plate heat exchanger is 200 kW, and the total heat exchange power of the two plate heat exchangers operating in parallel is 400 kW, which can quickly heat 50 cubic meters of water in the water pool 102 from room temperature to 40 degrees Celsius, and the heating time is about 2 hours. The temperature controller adopts a PID control algorithm to control the water temperature control accuracy within the range of plus or minus 2 degrees Celsius of the set temperature.

[0061] The multi-stage filter of the purification device 104 adopts a three-stage filtering structure, the first stage is mechanical filtration with a filter aperture of 100 microns to remove larger particles, the second stage is activated carbon filtration to adsorb organic matter and odors, and the third stage is precision filtration with a filter aperture of 10 microns to remove small particles and suspended solids. The treatment capacity of the purification device 104 is 20 cubic meters per hour, which can completely filter the water in the water pool 102 once every 12 hours, thereby ensuring the cleanliness of the water.

[0062] Further, in this embodiment, three independent training cabins are set up in the training area, each equipped with a complete set of flooding units 200. The three sets of flooding units 200 are connected in parallel to the water supply header 409, and each set of flooding units 200 can be independently controlled to achieve simultaneous training in multiple scenarios or step-by-step training with different difficulties.

[0063] Each set of flooding units 200 is equipped with two buffer tanks 205, installed at the cabin wall and the cabin bottom position of the training cabin, simulating two typical damage conditions of side break and bottom break. The two buffer tanks 205 can supply water simultaneously or separately, and are flexibly controlled by the central control unit.

[0064] The break panel 205-4 is equipped with five different types, including a 50mm diameter circular break, a 100mm diameter circular break, a 200mm diameter circular break, a long and narrow crack with a length of 100mm and a width of 20mm, and an irregular tear break. Before training, select the corresponding break panel 205-4 according to the training subject, and fix it with 8 M12 bolts and rubber sealing washers. The time to replace the break panel 205-4 is about 10 minutes.

[0065] The flow regulating valve 204 uses an electric ball valve with an adjustment accuracy of 1% and a response time of less than 5 seconds. The central control unit can preset multiple water inlet curves, such as stepwise water inlet, gradual water inlet, pulsatile water inlet, etc., to simulate different break expansion conditions and increase the complexity and authenticity of training.

[0066] Therefore, in actual training scenarios, different subject training can be carried out simultaneously in three training cabins. Training cabin one is set with a 50mm diameter side break, with a water supply flow rate of 5 cubic meters per hour and a water supply pressure of 0.2 megapascals, for basic plugging skill training. Training cabin two is set with a 100mm diameter bottom break, with a water supply flow rate of 15 cubic meters per hour and a water supply pressure of 0.3 megapascals, for intermediate plugging and drainage coordination training. Training cabin three is set with a 200mm diameter side break and a long and narrow crack bottom break, with a water supply flow rate of 50 cubic meters per hour and a water supply pressure of 0.4 megapascals, for advanced emergency disposal and team cooperation training.

[0067] The training water in the three training cabins is ultimately recycled to the water pool 102 through the respective drainage units 300, achieving efficient recycling of water resources. The central control unit simultaneously monitors the operating status of the three training cabins, records the plugging time, drainage rate, etc. of each group of training personnel, and generates a comparative analysis report after training.

[0068] The embodiment realizes high-intensity, multi-scene and multi-gradient breakage damage training by increasing the number of circulating water pumps, optimizing heating and purification capacity, and configuring multiple training cabins, thereby meeting the demand for large-scale centralized training.

[0069] Further, the application also provides a specific embodiment.

[0070] The embodiment focuses on optimizing the configuration of the drainage unit 300 and adding intelligent monitoring functions on the basis of the first embodiment.

[0071] The training cabin of the embodiment simulates the multi-deck structure of a real ship, and three decks are provided. The first deck is arranged with four floor drains 301, the second deck is arranged with four floor drains 301, and the third deck (the bottom layer) is arranged with six floor drains 301. Each floor drain 301 has a flow diameter of 100 mm and is equipped with a detachable filter screen to prevent debris such as leak stoppage materials from entering the drainage system.

[0072] The floor drains 301 of the three decks are respectively collected to three independent drainage branch pipes, and the three drainage branch pipes are collected to a backwater main pipe, i.e., the backwater pipeline 108. An electric valve 302 is arranged on each drainage branch pipe to control the drainage of each deck individually. A flow meter is arranged on the backwater main pipe to monitor the total drainage flow in real time.

[0073] The bottom layer of the training cabin is provided with a sump, and the size of the sump is 1 meter by 1 meter by 1.5 meters (length by width by height). The mobile submersible pump 308 is a stainless steel submersible sewage pump with a rated flow of 40 cubic meters per hour and a lift of 15 meters, and is equipped with a float switch. When the water level of the sump reaches 1.2 meters, the float switch automatically starts the submersible pump 308; when the water level drops to 0.3 meters, the float switch automatically stops the submersible pump 308, realizing automatic drainage function. The outlet of the mobile submersible pump 308 is connected to the backwater pipeline 108 through a quick connector 309, and the quick connector 309 adopts a clamp type connection, and the connection and disconnection time is less than 30 seconds.

[0074] The jet pump 303 is arranged on the second deck of the training cabin for easy operation by the trainees. The power water source 307 of the jet pump 303 comes from a branch pipeline of the water supply header 409, and the pressure is stabilized at 0.5 MPa through a pressure reducing valve. The suction port of the jet pump 303 extends into the water accumulation area through a 4-meter long hose, and a filter 306 is arranged at the end of the hose. The filter 306 has a filter pore size of 5 mm. The theoretical suction flow of the jet pump 303 is 15 cubic meters per hour, and the actual flow is reduced according to the suction height and pipeline loss, and the average flow is about 10 cubic meters per hour. The outlet butterfly valve 304 and the inlet butterfly valve 305 are both manually operated, and the trainees control the start and stop of the jet pump 303 by opening and closing the valves.

[0075] The embodiment adds multiple water level sensors and cameras in the training cabin to realize all-around monitoring of the training process.

[0076] The three decks of the training cabin are respectively installed with ultrasonic water level sensors, with a measurement range of 0 to 2 meters and a measurement accuracy of plus or minus 5 millimeters. The water level sensors monitor the water depth of each deck in real time, and the data is transmitted to the central control unit. When the water depth of a deck exceeds 0.5 meters, the central control unit issues an audible and visual alarm to remind the training personnel to speed up the drainage speed; when the water depth exceeds 1 meter, the central control unit automatically opens the electric valve 302 of the deck to force gravity drainage, and automatically starts the mobile submersible pump 308 for forced drainage, ensuring the safety of training.

[0077] Four waterproof cameras are installed in the training cabin, located in the four corners of the cabin, covering the entire training area. The cameras have an IP68 protection rating and can work normally underwater. The cameras take real-time videos of the training process, and the video signals are transmitted to the central control unit, allowing the training commander to observe the operation of the training personnel through the monitoring screen. The video is also recorded and can be played back after training for analysis, training review, and skill evaluation.

[0078] The central control unit is equipped with a data analysis module. Based on the data collected by the pressure sensors, flow meters, and water level sensors, the data analysis module automatically calculates the plugging efficiency, drainage efficiency, and team coordination efficiency of the training personnel. For example, the plugging efficiency is defined as the ratio of the completion time of the hole plugging to the standard time, and the drainage efficiency is defined as the ratio of the water discharge to the water inflow per unit time. The central control unit automatically scores these indicators and generates a training report card.

[0079] Further, the training process can include: The embodiment designs a standardized training process. Before training starts, the central control unit automatically checks the system status, including the water level, water temperature, circulating water pump operation status, valve status, etc., and only allows training to start after confirming that the system is normal.

[0080] During the training process, the central control unit monitors the water level, water inflow, and drainage flow of the training cabin in real time. When an abnormal situation is detected, such as rapid water level rise or drainage system failure, the central control unit immediately issues an alarm and automatically takes measures according to the pre-set emergency plan, such as closing the flow regulating valve 204 to stop water inflow, opening all electric valves 302 for full-speed drainage, and starting the mobile submersible pump 308 for forced drainage, to maximize the safety of training.

[0081] After the training is completed, the central control unit automatically executes a system reset process, including closing all water inlet valves, opening all water outlet valves to empty the training cabin, opening the relief valve 205-2 to empty the buffer tank 205, starting the purification device 104 to purify the recovered water, and the like. The system reset time is about 20 minutes, and after the reset is completed, the system can perform the next training.

[0082] The present embodiment optimizes the configuration of the drainage unit 300, increases intelligent monitoring functions, realizes the automation, intelligence and safety of the training process, improves the training efficiency and safety, and provides reliable protection for large-scale and high-frequency training of broken pipe leakage.
