Description

Technical Field

[0001] The present invention relates to the technical field of ship and ocean engineering equipment design and manufacturing, and in particular to an indoor ice water test device and a test method thereof for studying ice layer structural characteristics. Background Art

[0002] In recent years, global warming and the melting of polar ice have led to a surge in demand for icebreakers, polar research vessels, ice transport vessels, and other ice-travel marine engineering structures. Simultaneously, the demand for ship and marine structure testing is also increasing, necessitating the establishment of more ice-water test facilities.

[0003] The marine environment is highly complex, with sea ice exhibiting a variety of conditions. Combined with the loads of offshore wind, waves, and currents, complex marine operating conditions are created. The physical modulus of sea ice is spatially non-uniform, and its thickness varies. The structural mechanical characteristics of the ice layer, such as density and strength, contribute to its complex and variable conditions. The Ice Water Test Tank is a model test tank designed for icebreaking by surface and underwater vessels. By simulating the varying ice states and thicknesses in cold waters, it uses exciters, sensors, and laser vibrometers in a standard laboratory environment to test the structural mechanical properties, vibration modes, and vibration shape characteristics of ice layers of varying thicknesses, providing data reference for icebreaking research by both surface and underwater vessels.

[0004] In response to this demand, the existing technology has proposed some small ice-water test pool devices for ice-breaking characteristics research, such as an ice-water dynamic measurement test system for ship models in outdoor ice-water pools. This solution can reasonably constrain the ship model during outdoor ice-water pool tests, increase the stability of the ship model movement, and can carry measuring instruments for measuring various navigation postures of the ship model, not limited to ice resistance, thereby improving the integrity of the ice-water pool test measurement; a ship ice-water pool collision test device and experimental method, which can carry out structural response verification of the mechanical properties, ice shape, ice mass, ice speed, impact position, ship model buoyancy and impact angle of different ice materials, so as to better reflect the actual situation of the ship colliding with ice; an ice-water impact test device, which includes a temperature control device and an ice-water control device. The temperature control device includes a low-temperature control box and a high-temperature control box. The ice-water control device includes a water storage tank, a water pipe, a water nozzle and an intelligent water pump, which are used to test the ice-water impact resistance of the circuit system. However, these ice water pools all have the disadvantages of high construction cost, large floor space, complex structural design, poor feasibility of function realization, complex control, large size and high energy consumption during operation.

DETAILED DESCRIPTION

[0054] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0055] The following describes an indoor ice water test device and a test method for studying ice layer structural characteristics according to an embodiment of the present invention with reference to the accompanying drawings.

[0056] Figure 1 This is a structural schematic diagram of an indoor ice water test device provided by an embodiment of the present invention.

[0057] like Figure 1 As shown, the indoor ice water test device includes: an ice water test pool 100, a control cabinet 200 and a heat dissipation external unit 300.

[0058] The ice water test pool 100 is configured to execute at least one of the following modes: water storage mode, ice making mode, and demolding mode, based on execution instructions. The control cabinet 200 is connected to the ice water test pool 100 via a cable harness and is configured to generate execution instructions based on the target test requirements and the operating status of the ice water test pool 100, thereby controlling the ice water test pool 100. The heat dissipation unit 300 is connected to the ice water test pool 100 and is configured to cool the condensed working fluid in the condenser 107 when the ice water test pool 100 is in ice making mode, thereby exchanging heat with the ice water test pool 100.

[0059] In some embodiments, the ice water test pool includes a bottomless temperature control box and a roofless test pool. The bottomless temperature control box is arranged directly above the roofless test pool, and a heat-insulating and pressure-resistant layer 114 is provided at the connection between the bottomless temperature control box and the roofless test pool.

[0060] Specifically, if Figure 2-7 As shown, the ice water test pool includes a bottomless temperature-controlled box and a roofless test pool. The bottomless temperature-controlled box is arranged directly above the roofless test pool, and a heat-insulating and pressure-resistant layer 114 is provided at the connection between the bottomless temperature-controlled box and the roofless test pool. The bottomless temperature-controlled box includes: a frame 101, an ice-making guide wire 102, a sliding door 103, a temperature-controlled ventilation fan 104 and a removable heat-insulating cover 105. The roofless test pool includes an open container 106, a condenser 107, a laser rangefinder 108, a water exchange hole 109, a cabinet cable bundle hole 110 and a condensing working medium exchange hole 111.

[0061] Furthermore, in the bottomless temperature-controlled box, a movable screw 112 is provided on the frame 101, and the ice-making guide wire 102 is slidably connected to the frame 101 through a claw-shaped tray 113 on the movable screw 112, so that when the ice-making mode is executed, the ice-making guide wire 102 is slid to the water surface of the roofless test pool to guide the roofless test pool to freeze; the sliding door 103 is embedded with heat-insulating and pressure-resistant glass 115 to observe the execution process of the water storage mode, ice-making mode and demoulding mode. The sliding door 103 is set on the front of the frame 101 through built-in grooves and pulleys, and the edge is wrapped with insulating rubber to ensure temperature stability, so that when the ice-making mode is executed, the sliding door 103 is raised to close the roofless test pool to ensure the low temperature of the box. It is not affected, and it is convenient to monitor the freezing state and operation status of the ice-making guide wire 102 inside the test ice pool in real time, or in the demoulding mode, open the roofless test pool to facilitate the entry and exit of subsequent test equipment; the temperature-controlled ventilation fan 104 is installed on the back of the frame 101, that is, opposite to the sliding door 103, to exhaust and ventilate in the ice-making mode; the detachable insulation cover 105 includes thermal insulation material 116 and a sealing rubber ring 117, which is installed on the other three surfaces of the frame 101 except the front, back and bottom surfaces, so as to leave space for putting in and taking out the ice guide wire in the water storage mode and the demoulding stage. In the ice-making mode, the test ice pool is closed, or it can be disassembled when placing test instruments.

[0062] In addition, silicone glass glue is filled between the heat-insulating and pressure-resistant glass 115 and the sliding door 103 to ensure the stability of the glass when the movable door is raised or lowered, while filling the gap to prevent cold air from leaking out and isolating external air from entering the test pool and affecting the icing effect.

[0063] Furthermore, in the roofless test pool, the outer side panels of the open container 106 are thermal insulation layers, and the inner side panels are equipped with condenser tubes 107, which are arranged directly below the bottomless temperature control box to store water when the water storage mode is executed; the laser rangefinder 108 is arranged at the bottom of the condenser tube 107 to monitor the thickness of the ice surface when the ice making mode is executed; the condenser tubes 107 are evenly arranged on the side walls of the open container 106 and are connected to the heat dissipation external unit to self-heat the surface of the ice layer when the demolding mode is executed, so as to separate the ice making guide wire 102 from the surface of the ice layer; the water exchange hole 109 is installed on any side of the open container 106 to inject water into the open container 106 when the water storage mode is executed; the cabinet cable bundle hole 110 is installed above the water exchange hole 109 to connect to the control cabinet; the condensed working medium exchange hole 111 is arranged around the condenser tube 107 to cooperate with the condenser tube 107 to exchange heat with the ice water test device.

[0064] In some embodiments, the control cabinet includes:

[0065] The first control button is used to control the raising or lowering of the sliding door 103 of the ice water test tank to cooperate with the execution of ice making mode, demoulding mode, installation or removal of test instruments and models, etc.;

[0066] The second control button is used to control the opening or closing of the heat dissipation outdoor unit to cooperate with the execution of the ice making mode;

[0067] The third control button is used to control the opening or closing of the temperature-controlled ventilation fan 104 and the condenser tube 107 to cooperate with the execution of the demoulding mode;

[0068] Emergency stop button, used to force stop the operation of the ice water test pool in case of an accident;

[0069] Cabinets are used to integrate test instruments, power conditioners, power amplifiers, data acquisition instruments and servers for target test needs.

[0070] In the actual implementation process, the control cabinet includes a first control button, a second control button, a third control button, an emergency stop button, a liquid crystal display, an engineering keyboard and mouse, and a cabinet 207, wherein:

[0071] The emergency stop button can force the equipment to stop in the event of an accident. The first control button controls the lifting and lowering of the sliding door 103 in the small ice water test pool to control the ice water test pool to be in a closed state, and to install or remove test instruments and models; the second control button controls the ice water test pool and the heat dissipation outdoor unit, and turns on the ice making mode through the cooperation of the condenser 107, the heat dissipation outdoor unit and other components; the third control button turns on the insulation mode by controlling the condenser 107, the temperature-controlled ventilation fan 104 and other components to perform subsequent test operations.

[0072] The second control button turns on the cooling mode, and the condenser 107 and the cooling outdoor unit operate to cool the ice water test pool. By cooperating with the claw-shaped tray 113 on the moving screw 112, the ice-making guide wire 102 is placed flush with the water surface. The ice-making guide wire 102 guides the ice layer to freeze. The laser rangefinder 108 is located at the bottom of the condenser 107 to monitor the thickness of the ice layer in real time.

[0073] When the ice reaches a set thickness, the second control button turns on the demoulding mode, and the ice making guide wire 102 self-heats to demould the layered ice.

[0074] After the ice layer falls off from the ice making guide wire 102, the slidable movable door is controlled to descend by the second control button to open the device, and the ice making guide wire 102 is taken out of the test pool, and some uneven ice surfaces are manually polished and trimmed.

[0075] The cabinet 207 is equipped with test instruments, power conditioners, power amplifiers, data acquisition instruments, servers and other equipment required for the target experiment, and multiple apertures of different sizes are reserved to facilitate the integration of these equipment.

[0076] The liquid crystal display screen 205 and the engineering keyboard and mouse 206 are used to display corresponding data and control corresponding buttons.

[0077] Taking an icebreaking test as an example, the specific working process of the invented device is as follows:

[0078] (1) Prepare for the test phase, i.e., the water storage mode. The sliding door is lowered into the test ice pool, the detachable insulation cover 105 is removed, and water is stored in the test pool through the water exchange hole 109, at least covering the condenser 107. By cooperating with the claw-shaped tray 113 on the movable screw 112, the ice-making guide wire 102 is placed to be flush with the water surface, the sliding door is raised, the detachable insulation cover 105 is reset, and the sliding door is tightly closed to ensure that the cold air in the test ice pool does not leak out. Check that all components are installed correctly and operate normally, connect the pipes and equipment cable harnesses, and the test preparation is completed.

[0079] (2) Experimental ice making, i.e. ice making mode, is performed by turning on the device through the first control button and the second control button in the control cabinet to enter the ice making mode. The heat dissipation unit exchanges and cools the condensing medium in the condenser tube 107, and the temperature-controlled ventilation fan 104 performs exhaust ventilation. The temperature in the ice water pool drops rapidly, and crystals adhere to the ice making guide wire 102 and freeze. The laser rangefinder 108 monitors the thickness of the ice layer in real time. When the thickness reaches the standard, the signal is transmitted to the control cabinet, and ice making is completed.

[0080] (3) Insulation demoulding, i.e. demoulding mode, the device is turned on by the third control button of the control cabinet to enter the demoulding mode, the ice-making guide wire 102 is self-heated to demould the generated ice layer, and the inside of the test pool can be observed through the heat-insulating pressure-resistant glass 115. After observing that the layered ice is separated from the ice-making guide wire 102, the sliding door is lowered by the first control button of the control cabinet, and the detachable heat-insulating cover 105 is removed and the ice-making guide wire 102 is taken out to complete the demoulding.

[0081] (4) After the ice layer is demolded, the subsequent experimental equipment such as the vibrator, laser vibrometer, sensor, underwater icebreaking device, etc. are placed, the detachable insulation cover 105 is reset, the sliding door is raised, and the sensor cables inside the device are connected to the control cabinet through the cable bundle hole. After assembly, the icebreaking test can be carried out.

[0082] (5) Connect various sensors, power amplifiers, exciters and acquisition equipment, check the channel status after turning them on, and input excitation in the form of sweep frequency, fixed frequency, measured frequency, pulse, etc. In static tests, strain gauges can be installed at specific points to monitor the response curve of the ice layer when subjected to different excitations, or stress gauges can be installed to monitor the stress distribution of the ice layer; in dynamic tests, ice modal analysis and response spectrum analysis can be carried out through hammering method, laser vibrometer method, etc., and the deformation process and destruction process of ice layers of different thicknesses can be observed and tested through high-speed cameras and laser vibrometers arranged at the bottom of the pool.

[0083] In summary, the indoor ice-water test apparatus proposed in the embodiments of the present invention has a simple structure, a small footprint, low construction costs, high functional feasibility, simple control, and low energy consumption. Based on the needs of icebreaking research, it can be used in a standard laboratory environment with an exciter, sensors, and a laser vibrometer to test the mechanical properties and vibration modes of ice layers of varying thicknesses, providing data support for icebreaking research on both surface and underwater vessels. This invention possesses advantages such as simple structure, easy operation, and wide applicability.
