[0019] In order to enhance the experimental verification effect of polar marine equipment, there is an urgent need for a test device that can jointly simulate the interaction of ice, waves, and currents.

[0020] To this end, an ice-wave-current combined generation test device applicable to an ice tank provided by an embodiment of the present invention can be used to simulate the interaction of floating ice, water flow, and waves in a low-temperature environment, providing an experimental platform that can more realistically simulate the polar marine environment.

[0021] At least one embodiment of the present invention provides an ice-wave-current combined generation test device applicable to an ice tank, including: a water tank, a wave-making mechanism, an ice-pushing mechanism, and an ice floe conveying mechanism that are sequentially installed on the water tank from the head end to the tail end. A water flow generating mechanism is also installed in the water tank to provide flowing water into the water tank. The wave-making mechanism includes a swing driving component and a wave-making plate connected to its moving end to drive the wave-making plate to swing around its bottom. The ice-pushing mechanism includes a first conveyor belt and first rotating drums connected to both ends of the first conveyor belt. The first conveyor belt is located at a position near the head end of the water tank to convey external ice floes into the test area in the water tank. The ice floe conveying mechanism includes a second conveyor belt and second rotating drums connected to both ends of the second conveyor belt. The first rotating drum and the second rotating drum are connected through a transmission mechanism to make the first conveyor belt and the second conveyor belt move synchronously. The second conveyor belt is located at a position near the tail end of the water tank to convey the ice floes in the water tank out of the water tank.

[0022] In the ice-wave-current combined generation test device applicable to an ice tank provided by the above embodiment of the present invention, water is fed into the water tank through the water flow generating mechanism, the wave-making plate is driven to reciprocate by the swing driving component in the wave-making mechanism, the swing driving component changes the swing direction and speed of the wave-making plate to push the water in the water tank to simulate waves, and the first rotating drum drives the first conveyor belt to move to convey external ice floes into the water tank, thereby enhancing the interaction between the ice floes, the water flow, and the waves, and being able to create a real polar ice floe environment in the ice tank.

[0023] The present invention will be described below through several specific embodiments. To keep the description below of the embodiments of the present invention clear and concise, detailed descriptions of known functions and known components may be omitted. When any component of the embodiments of the present invention appears in more than one drawing, the component may be denoted by the same reference numeral in each drawing.

[0024] Reference Figure 1 、 2 , 3, and 4, where Figure 1 is a first perspective three-dimensional view of an ice-wave-current combined generation test device applicable to an ice tank provided by an embodiment of the present invention, Figure 2 is a top view of an ice-wave-current combined generation test device applicable to an ice tank provided by an embodiment of the present invention, Figure 3 is a second perspective three-dimensional view of an ice-wave-current combined generation test device applicable to an ice tank provided by an embodiment of the present invention, Figure 4 is a schematic connection structure diagram of a ice-pushing mechanism and an ice floe conveying mechanism provided by an embodiment of the present invention, as shown in Figure 1 、 2, as shown in Figures 3 and 4, an ice-wave-current combined generation test device applicable to an ice pool provided by an embodiment of the present invention includes: a pool and a wave-making mechanism 1, an ice-pushing mechanism 4, and an ice floe conveying mechanism 6 sequentially installed on the pool from the head end to the tail end. The pool is used to accommodate the water body, ice floes, and the test environment for simulating waves and currents required for the test. The size and depth of the pool can be designed according to experimental requirements and are usually built with high-strength materials to withstand the combined action of ice, waves, and currents. A water current generating mechanism 2 is also installed in the pool to provide flowing water into the pool. The wave-making mechanism 1 includes a swing driving component and a wave-making plate 1-1 connected to its moving end to drive the wave-making plate 1-1 to swing around its bottom. The wave-making plate 1-1 is usually made of high-strength and corrosion-resistant materials. The ice-pushing mechanism 4 includes a first conveyor belt 4-3 and first rotating drums 4-2 connected to both ends of its head and tail. The first conveyor belt 4-3 is located at the position of the pool near the head end to convey external ice floes to the test area in the pool. The ice floe conveying mechanism 6 includes a second conveyor belt 6-1 and second rotating drums 6-2 connected to both ends of its head and tail. The first rotating drum 4-2 and the second rotating drum 6-2 are connected by a transmission mechanism to make the first conveyor belt 4-3 and the second conveyor belt 6-1 move synchronously. The second conveyor belt 6-1 is located at the position of the pool near the tail end to convey the ice floes in the pool to the outside of the pool. The wave-making mechanism 1 selects a low-temperature-resistant electric wave-making mechanism. The electric control system generates adjustable waves. By adjusting the wavelength, wave height, and frequency of the waves, the wave characteristics in polar seas can be simulated. The parameters of the waves can be finely adjusted according to test requirements to reproduce the wave conditions under different environmental conditions. The water current generating mechanism 2 is used to generate adjustable-speed water currents to simulate the changes in water currents in polar seas, especially complex water current states such as tidal currents, ice drifts, and wind-driven currents, to ensure that the influence and interaction of water currents on ice floes can be reproduced, and is used to generate directional water currents and superimpose them with waves. The driving motor 4-1 controls the rotation speed of the first rotating drum 4-2, thereby adjusting the moving speed of the first conveyor belt 4-3. The first rotating drum 4-2 is fixedly connected to the driving motor 4-1. When the rotation speed of the first rotating drum 4-2 changes, it will directly affect the speed of ice floe conveyance, thereby adjusting the speed and direction of ice floe pushing. The ice-pushing mechanism 4 and the ice floe conveying mechanism 6 are linked by a conveyor belt, such as Figure 4As shown, there is a belt drive between the first rotating drum 4-2 and the second rotating drum 6-2. The ice pushing mechanism 4 sends floating ice to the test area. Through this linkage mechanism, under the action of water flow and waves, the floating ice can simulate dynamic behaviors such as drifting, rotating and colliding. In addition, the speed and direction of the ice pushing mechanism 4 are adjustable to ensure that the motion state of the floating ice can be precisely adjusted according to the experimental requirements, so that the behavior of the floating ice meets the preset experimental requirements. This flexible adjustment mechanism enables the device to adapt to various test conditions and perform precise dynamic simulations in different water flow and wave environments. The ice pushing mechanism 4 and the floating ice conveying mechanism 6 are linked through a belt drive to simulate the dynamic behaviors of the floating ice such as drifting, rotating and colliding under the action of water flow and waves.

[0025] An ice-wave-current combined generation test device applicable to an ice tank provided by an embodiment of the present invention aims to solve the problem that the existing ice tank cannot simultaneously simulate the comprehensive effects of ice, waves and currents, so as to improve the experimental verification effect of polar marine equipment. The device can simulate the complex environment in polar floating ice waters. During the test, the wave-making mechanism and the water current generating mechanism work together to generate a water current and wave environment similar to that in the actual polar sea area. The ice pushing mechanism sends floating ice into the test area, and together with the waves and water current, simulates the behavior of floating ice in the polar sea area. Specifically, a water current is sent into the tank through the water current generating mechanism, the wave-making plate is driven to reciprocate by the swing driving component in the wave-making mechanism, and the swing direction and speed of the wave-making plate are changed by the swing driving component to push the water in the tank to simulate waves. The first conveyor belt is driven to move by the first rotating drum to transport external floating ice into the tank, thereby enhancing the interaction between the floating ice, water current and waves, being able to create a real polar floating ice environment in the ice tank, precisely simulate the complex dynamic process in polar floating ice waters, provide more reliable experimental data, promote the research and development and optimization of polar marine equipment, overcome the limitation that the conventional ice tank only has the function of making ice, and provide more reliable experimental data support for the research and development of polar marine equipment.

[0026] Refer again to Figure 3, One end of the first conveyor belt 4-3 and the second conveyor belt 6-1 is located outside the pool, and the other ends of the first conveyor belt 4-3 and the second conveyor belt 6-1 are located inside the pool. It should be noted that the end of the first conveyor belt 4-3 located inside the pool can be connected to an inclined guide plate to convey the floating ice on the first conveyor belt 4-3 to the test area. One end of the first conveyor belt 4-3 is usually connected to a floating ice storage device or a floating ice preparation system, and external floating ice is loaded onto the conveyor belt through this end and extends into the pool. The other end of the first conveyor belt 4-3 is close to the starting position of the test area, and the floating ice is conveyed to the test area in the pool through this end. The first conveyor belt 4-3 is driven by the first rotating roller 4-2 and operates continuously or intermittently to ensure that the floating ice can enter the pool orderly. The running speed of the first conveyor belt 4-3 can be adjusted by the control system to meet different experimental requirements. For example, when a large amount of floating ice is needed, the speed of the conveyor belt can be increased; when precise control of the number of floating ice is required, the speed can be reduced or an intermittent operation mode can be adopted. It is usually made of high-strength, low-temperature-resistant rubber or composite materials to ensure good flexibility and durability in a low-temperature environment. The surface of the conveyor belt may be designed with anti-slip textures or raised structures to prevent the floating ice from sliding or piling up during transportation. The loading end, which is the end located outside the pool, is usually equipped with a floating ice guiding device to ensure that the floating ice can smoothly enter the conveyor belt. The unloading end, which is the end located inside the pool, is designed with an inclined or slide structure to enable the floating ice to smoothly slide into the test area in the pool. The second conveyor belt 6-1 is mainly used to remove the floating ice after the test from the pool. The end of the second conveyor belt 6-1 located inside the pool is at the end of the pool, close to the end position of the test area. The floating ice after the test is loaded onto the conveyor belt through this end, and the end located outside the pool extends outside the pool and is usually connected to a floating ice collection device or a processing system. The floating ice is conveyed outside the pool through this end. The second conveyor belt 6-1 runs synchronously with the first conveyor belt 4-3 through a transmission mechanism to ensure the coordination of the floating ice transportation and cleaning processes. The speed of the second conveyor belt 6-1 is consistent with that of the first conveyor belt 4-3 to avoid the accumulation or jamming of the floating ice during transportation.

[0027] Specifically, the first rotating roller 4-2 is connected to a driving motor 4-1, and the moving speeds of the first conveyor belt 4-3 and the second conveyor belt 6-1 are adjusted by adjusting the rotation speed of the driving motor 4-1.

[0028] Reference Figure 3 and Figure 5 , Figure 5 is a partial structural schematic diagram of the water flow generating mechanism provided by the embodiment of the present invention. As Figure 3 and Figure 5As shown in the figure, the water flow generating mechanism 2 includes a water pump 2-1 and a diversion pipeline 2-3 connected thereto. The outlet of the diversion pipeline 2-3 is located in the pool, and a flow regulating valve 2-2 is provided on the diversion pipeline 2-3. The main function of the diversion pipeline 2-3 is to guide the circulating water flow, which is superimposed with the waves generated by the wave-making mechanism 1 in the test area. Its relative position usually maintains a balanced relationship with the wave-making board 1-1 and the first rotating drum 4-2. The water pump 2-1 provides the power for the circulating water flow, the flow regulating valve 2-2 is used to control the water flow speed and direction, and the diversion pipeline 2-3 transports the water flow to the test area.

[0029] While the wave-making board 1-1 generates waves, the water flow generating mechanism 2 below the pool is started. The water pump 2-1 generates controllable water flow through the flow regulating valve 2-2, and cooperates with the flow velocity regulating valve to adjust the water flow intensity, so that the waves and the water flow interact in the experimental area to form a complex flow field environment.

[0030] Reference Figure 6 , Figure 6 is a schematic structural diagram of the wave-making mechanism provided by the embodiment of the present invention. As Figure 6 shown, the wave-making mechanism 1 in the embodiment of the present invention selects a rocking type wave-making machine. The swing driving component includes: a support frame 1-2 and a linear movement component. The support frame 1-2 is fixed on the top of the pool, and the linear movement component is located at the bottom of the pool. Both ends of the wave-making board 1-1 are rotatably connected to the support frame 1-2, and the bottom of the wave-making board 1-1 is rotatably connected to the moving end of the linear movement component. The linear movement component can be a lead screw nut, a crank slider, a connecting rod mechanism, etc. In this embodiment, a lead screw nut assembly is selected. The motor 1-3 is fixed on the pool, and a lead screw 1-4 is fixed on its output shaft. The lead screw 1-4 is rotatably connected inside the bottom plate of the pool. A groove is opened on the bottom plate. A nut seat 1-5 is screwed on the lead screw 1-4. The nut seat 1-5 is slidably matched with the groove. The bottom of the wave-making board 1-1 is rotatably connected to the nut seat 1-5, such as through a rotating shaft connection, and the top is rotatably connected to the support frame 1-2. As the output shaft of the motor 1-3 rotates, the nut seat 1-5 moves linearly, thereby driving the wave-making board 1-1 to swing around the support frame 1-2. By controlling the rotation speed and rotation direction of the motor 1-3, the frequency and wave height of the waves are adjusted.

[0031] Refer to again Figure 1 and Figure 2 , a water guiding groove 3 is further provided in the pool. The water guiding groove 3 connects the head end and the tail end of the pool, and the water guiding groove 3 is connected to the water pump 2-1 and the diversion pipeline 2-3 so as to circulate the water in the pool.

[0032] The diversion pipeline 2-3 evenly guides the water flow to the test area. The diversion water channel 3 connects the head and tail ends of the water pool to complete the water flow circulation, and after the test, it guides the water flow back to the water flow generating mechanism 2, thus maintaining the smoothness and stability of the water flow circulation throughout the experiment. The diversion water channel 3 facilitates the water supply and drainage of the water pipe openings at the bottom of the water pool and provides a space to install a water pump by the way.

[0033] Optionally, the surface of the diversion water channel 3 has a lining coating to prevent the water in the water pool from freezing and ensure the unobstructed water flow. According to the size of the water pool and the experimental requirements, the diversion water channel 3 is designed in a straight shape, an arc shape or other specific shapes to optimize the water flow guiding effect. It is usually installed on the side wall or bottom of the water pool and connected to the water flow generating mechanism 2 to ensure that the water flow can smoothly enter the diversion water channel. The height, depth and length of the diversion water channel 3 are designed according to the scale of the water pool and the water flow requirements to ensure that the water flow can be evenly distributed. To prevent the water in the water pool from freezing in a low-temperature environment, the surface of the diversion water channel 3 is coated with a special lining coating, and this coating has the following characteristics: low freezing point characteristic: the material of the lining coating has a low freezing point characteristic, which can effectively delay the speed of water freezing; hydrophobicity: the surface of the coating has hydrophobicity, which can reduce the contact area between water and the surface of the channel body and reduce the possibility of freezing; frost resistance: in an extremely low-temperature environment, the coating can still maintain good flexibility and adhesion, avoiding cracking or peeling due to temperature changes; high wear resistance: the coating can withstand the long-term scouring of the water flow and the friction of floating ice, ensuring that it will not fail due to wear during the experiment; corrosion resistance: the coating material has excellent corrosion resistance and can resist the erosion of seawater or other chemical substances, extending the service life of the diversion water channel.

[0034] The construction process of the lining coating is crucial for the performance of the diversion water channel and usually includes the following steps: Surface treatment: Before coating the coating, clean and polish the surface of the diversion water channel to ensure that the surface is flat and free of impurities; Coating application: Use spraying, brushing or dipping and other methods to evenly apply the coating on the surface of the diversion water channel; Curing treatment: Through heating or natural curing, make the coating tightly combine with the surface of the channel body to form a solid protective layer; Quality inspection: Detect the thickness, uniformity and adhesion of the coating to ensure that its performance meets the requirements.

[0035] To ensure the accuracy of the test data, in the embodiments of the present invention, refer to Figure 7 and Figure 8 , Figure 7 is the structural schematic diagram of the flow velocity sensor device provided by the embodiments of the present invention, Figure 8 is the structural schematic diagram of the floating ice movement monitor provided by the embodiments of the present invention, as Figure 7 and Figure 8As shown in the figure, a flow velocity sensor 7 and an ice floe movement monitor 8 are also arranged in the water tank. The flow velocity sensor 7 is used to monitor the water flow velocity in the test area of the water tank, and the ice floe movement monitor 8 is used to monitor the state of the ice floe.

[0036] Specifically, the ice floe movement monitor 8 includes a camera module 8-1 and an analysis module 8-2 which are connected to each other. The camera module 8-1 is used to obtain the ice floe image information in the water tank. The analysis module 8-2 forms the movement trajectory and speed of the ice floe according to the ice floe image information, and adjusts the movement speed and direction of the wave-making board 1-1 according to the movement trajectory and speed of the ice floe. The flow velocity sensor 7 is installed in the test area and is used to monitor the water flow velocity. Its main components include a flow velocity probe 7-1 for measuring the water flow velocity, and a data acquisition module 7-2 for real-time display and recording of the flow velocity data. The flow velocity sensor 7 can ensure that the water flow velocity is consistent with the preset target, while the ice floe movement monitor provides the speed, direction and position data of the ice floe, so as to accurately track the dynamic changes of the ice floe.

[0037] Reference Figure 9 , Figure 9 is a schematic structural diagram of the ice floe recovery component provided by the embodiment of the present invention. As Figure 9 shown, one end of the ice floe conveying mechanism 6 located in the water tank is connected to an inclined ice floe recovery component 5. The ice floe recovery component 5 includes a vertically connected recovery mesh plate 5-1 and a wave-dissipating mesh 5-2. The bottom of the recovery mesh plate 5-1 is fixed to the bottom of the water tank, and the top of the wave-dissipating mesh 5-2 is connected to the second conveyor belt 6-1, so that the ice floes filtered by the recovery mesh plate 5-1 and the wave-dissipating mesh 5-2 enter the second conveyor belt 6-1 and are conveyed out of the water tank.

[0038] The ice floe conveying mechanism 6 is used to convey the recovered ice floes to the starting point of the test area, and is connected end to end with the ice floe recovery component 5 (which also serves as a wave-dissipating board). The ice floe recovery component 5 is located at the end of the ice water tank, which can not only recover the ice floes, but also effectively reduce the interference of waves. The ice floe conveying mechanism 6 can eliminate the unstable factors brought by waves during the experiment, ensure the accuracy of the wave experiment. The recovery mesh plate 5-1 is used for intercepting and recovering the ice floes, and the wave-dissipating mesh 5-2 can reduce the wave reflection at the end of the test.

[0039] Specifically, the height of the wave-dissipating mesh 5-2 is less than the height of the recovery mesh plate 5-1. The recovery mesh plate 5-1 is located underwater and serves as the main interception structure, while the wave-dissipating mesh 5-2 serves as a transition part.

[0040] Through the coordinated work of the above-mentioned various devices, this test device can jointly simulate the interaction of ice, water flow and waves in the polar sea area, provide a more real and reliable experimental environment for the research, design and verification of polar marine equipment, and significantly improve the safety, stability and performance of the equipment in the polar environment.

[0041] An ice-wave-current combined generation test device applicable to an ice tank according to an embodiment of the present invention installs a wave-making mechanism 1 at the head end of the ice tank. The wave-making board 1-1 is firmly fixed to the bottom of the experimental tank through a fixed bracket (1-2) to ensure the smooth propagation of waves. At the same time,

[0042] An ice-wave-current combined generation test device applicable to an ice tank according to an embodiment of the present invention installs a wave-making mechanism 1 at the head end of the ice tank. The wave-making board 1-1 is firmly fixed to the bottom of the experimental tank through a support frame 1-2 to ensure the smooth propagation of waves. At the same time, water flow is introduced into the experimental area through a water guide trough 3, and the diversion pipeline 2-3 of the trough body ensures the efficient circulation of water flow. On this basis, the ice-pushing mechanism 4 located in the middle of the tank pushes the preset floating ice along a specific trajectory at a stable speed to the test area through a first rotating roller 4-2. A floating ice positioning device is arranged at the end of the first conveyor belt 4-3. This device adapts to the shape and size of the floating ice, fixes the floating ice through mechanical clamping or positioning grooves, and ensures that the floating ice will not slide, rotate or shift due to uneven force or external interference during the pushing process, so as to ensure that the floating ice can accurately enter the test area and interact with the water flow and waves in subsequent experiments. After entering the experimental area, the floating ice floats and moves in the wave-current environment, and its trajectory and speed are captured in real time by a floating ice motion monitor 8 above the tank. The camera module 8-1 in the monitor is responsible for recording the movement of the floating ice, and the analysis module 8-2 transmits the trajectory data to the central control system. Combining with the water flow speed data fed back by the flow velocity sensor 7, the operating parameters of the wave-making mechanism 1 and the water flow generating mechanism 2 are adjusted in real time to maintain the accuracy and stability of the experiment.

[0043] A floating ice recovery component 5 is arranged at the end of the tank. Its porous recovery mesh plate 5-1 effectively absorbs wave energy, and at the same time, the recovery mesh plate 5-2 sends the floating ice drifting here into the collection tank for subsequent experimental recycling. To ensure that the floating ice can return to its initial state, a floating ice conveying mechanism 6 is also equipped above the ice tank. This device realizes the recovery and conveying operations of the floating ice through an internal drive system. Among them, the drive wheel provides power to drive the annular conveyor belt to run, and conveys the floating ice in the collection tank to the ice-pushing device one by one. To ensure the stability and efficiency of the floating ice conveying process, the conveying system is equipped with a speed control module, which can accurately adjust the conveying speed according to the experimental requirements. The surface of the conveyor belt has been specially treated and has an anti-slip function, which can effectively prevent the floating ice from shifting or slipping during the conveying process. At the same time, the rotation speed of the drive wheel and the tension of the conveyor belt can be adjusted to adapt to floating ice of different sizes, shapes and weights, improve the compatibility and applicability of the system, and thus ensure the continuity and accuracy of the entire experimental process.

[0044] Through a reasonable linkage mechanism, the entire device sequentially realizes the processes of wave generation, water flow superposition, floating ice pushing, dynamic monitoring, and recycling and reuse, thereby constructing a high-precision and highly restored polar ice-wave-current combined experimental environment, providing reliable technical support for the research on ship performance in polar environments. The above are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
