Description

Technical Field

[0001] The present invention belongs to the technical field of submersible testing, and in particular relates to a testing device for simulating an actual marine service environment and a method for using the same. Background Art

[0002] In recent years, submersibles have been widely used in civil and military fields, undertaking tasks such as marine environmental monitoring and seabed environmental mapping. However, the complex seabed topography, the alternating hot and cold liquid flow field environment, and the salt spray corrosion of the seawater itself can cause adverse effects on submersibles, such as poor navigation stability and surface corrosion damage. In particular, there are difficult problems such as the attitude adjustment and hovering of submersibles in a multi-factor coupling environment, the track turbulence problem when multiple test objects are working simultaneously, the driving stability problem under complex terrain, and the track planning problem under complex working conditions. Therefore, it is necessary to design a test device that can simulate a certain environment in the marine service environment to conduct corrosion and aging performance testing and evaluation of submersibles. For example, patent CN104155233B discloses a test device that simulates a wave splash zone, and patent CN202494622U discloses an accelerated corrosion test device for simulating a tidal range environment.

[0003] However, there is no experimental device in the existing technology that can couple multiple factors such as complex topography, ambient temperature, seawater flow rate, wind direction and range, water depth pressure, and salt spray corrosion. It is also impossible to carry out relevant research on the navigation planning problems of single objects under complex terrain and the track turbulence coupling problems of group objects, making it impossible to carry out comprehensive evaluation of shape optimization design, resistance to complex working conditions interference, and manufacturing material resistance to high temperature, corrosion, and high-speed coupling environments.

[0067] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0068] like Figure 1 and Figure 20 A specific embodiment of a test device method for simulating an actual marine service environment of the present invention is shown, comprising a box body 1, a bottom plate 2 detachably mounted to the box body 1, a plurality of simulation areas 3 arranged on the bottom plate 2 or the side wall of the box body 1, a wave-making mechanism 4 and a water depth pressure simulation mechanism 5 mounted on the side wall of the box body 1, a sea breeze simulation mechanism 6 mounted on the box body 1, a first lighting module 7 distributed on the box body 1, and a plurality of first vision capture modules 8 mounted on the bottom plate 2 and the inner wall of the box body 1. It is further explained that in this embodiment, any simulation area 3 includes a polygonal sunken surface 31 arranged on the inner surface of the bottom plate 2 or the inner wall of the box body 1, a plurality of telescopic drive mechanisms 32 vertically arranged on the polygonal sunken surface 31, a three-dimensional lifting column 33 fixedly connected to the telescopic end of part of the telescopic drive mechanism 32, a second vision capture module 34 fixedly connected to the telescopic end of another part of the telescopic drive mechanism 32, a temperature adjustment module 35 evenly distributed on the polygonal sunken surface 31, and a plurality of foaming modules 36 mounted on the polygonal sunken surface 31; the temperature adjustment module 35 is mounted on the three-dimensional lifting column 33 at the corresponding position.

[0069] Among them, a number of three-dimensional lifting columns 33 simulate different heights and shapes of ocean bottom landforms by extending and retracting the corresponding telescopic drive mechanism 32 in the height direction; a number of second vision capture modules 34 are distributed and installed on the edge of the polygonal sunken surface 31, and second lighting modules 37 are evenly distributed on the polygonal sunken surface 31. The second lighting modules 37 are installed on the top or side of the three-dimensional lifting columns 33 at the corresponding positions. Several second vision capture modules 34 are distributed on the edge of the polygonal sunken surface 31 in a simulation area 3, such as Figure 4 As shown, the second visual capture module 34 is installed at the telescopic end of the corresponding telescopic drive mechanism 32. The second visual capture module 34 can be adjusted in height following the corresponding telescopic drive mechanism 32 to accurately capture the 3D view of the test object and its motion state at different times.

[0070] The experimental device of the present invention is provided with a wave-making mechanism 4, a water depth pressure simulation mechanism 5, and a sea breeze simulation mechanism 6 to form a marine service environment, and multiple simulation areas 3 are set on the bottom plate 2 or the side wall of the box 1. The simulation area 3 is fully covered with a number of telescopic drive mechanisms 32. The telescopic drive mechanism 32 has a telescopic direction perpendicular to the polygonal sinking surface 31. A number of three-dimensional lifting columns 33 adjust their height relative to the polygonal sinking surface 31 through the corresponding telescopic drive mechanism 32 to simulate the ocean seabed topography and provide different working environments for the test objects. In addition, temperature adjustment devices are provided on some of the three-dimensional lifting columns 33, and a number of foaming modules 36 are provided on the polygonal sinking surface 31. The effects of multiple factors such as complex topography, ambient temperature, seawater flow rate, wind direction and range, water depth pressure, and salt spray corrosion on the test objects are coupled to comprehensively evaluate the service performance of the test objects in a complex marine environment. This solves the problem in the prior art that, due to incomplete simulation of the marine environment, it is impossible to perform shape optimization design, resistance to interference from complex working conditions, and comprehensive evaluation of the manufacturing material's resistance to high temperature, corrosion, and high-speed coupling environments.

[0071] It should be further explained that the multiple simulation areas 3 are in different shapes, and the polygonal sunken surface 31 includes one of a triangular plane, a rectangular plane, a circular plane and a hexagonal plane.

[0072] Example 1

[0073] The first embodiment includes four simulation areas 3 , whose corresponding polygonal sunken surfaces 31 are respectively triangular, rectangular, circular and hexagonal planes, and the four simulation areas 3 are all arranged on the bottom plate 2 .

[0074] like Figures 1 to 15As shown, the bottom plate 2 and the box body 1 in the present embodiment 1 are detachably connected, and four simulation areas 3 of different shapes are distributed on the inner surface of the bottom plate 2. Any simulation area 3 includes a polygonal sunken surface 31, and a number of telescopic drive mechanisms 32 are distributed inside the polygonal sunken surface 31. Most of the telescopic drive mechanisms 32 are fixedly connected to the three-dimensional lifting columns 33 at their telescopic ends, and another small part of the telescopic drive mechanisms 32 are fixedly connected to the second vision capture modules 34 at their telescopic ends. A number of foaming modules 36 and evenly distributed temperature adjustment modules 35 are installed on the polygonal sunken surface 31. The temperature adjustment modules 35 are installed on the three-dimensional lifting columns 33 at corresponding positions, and the second vision capture modules 34 are distributed and installed on the edge of the polygonal sunken surface 31. Second lighting modules 37 are evenly distributed on the polygonal sunken surface 31, and the second lighting modules 37 are installed on the top or side of the three-dimensional lifting columns 33 at corresponding positions. In more specific use, a portion of the telescopic drive mechanism 32 is used to control the elevation of the three-dimensional lifting column 33 within a certain distance. This allows the three-dimensional lifting column 6 to move up and down to different heights to simulate complex ocean floor topography. Another portion of the telescopic drive mechanism 32 is used to control the underwater position of the second visual capture module 34, adapting it to the simulated ocean floor topography of the simulation area 3, enabling accurate information capture of the test subject. The three-dimensional lifting column 33 in this first embodiment adopts a rectangular parallelepiped structure or a cylindrical structure with rounded edges. To reduce the impact of water on the three-dimensional lifting column 33 and the mutual influence between the three-dimensional lifting columns 33, the three-dimensional lifting column 33 in this embodiment can be a cylindrical structure with rounded edges.

[0075] The ocean floor landforms in this embodiment include submarine plain landforms, submarine trench landforms, submarine ridge landforms, and submarine hill landforms. Specifically, the height adjustment of the three-dimensional lifting column 6 is as follows: Figures 16 to 19 Specifically, in the first embodiment, the triangular simulation area is used to simulate the submarine plain landform, the hexagonal simulation area is used to simulate the submarine trench landform, the circular simulation area is used to simulate the submarine ridge landform, and the rectangular simulation area is used to simulate the submarine hill landform.

[0076] When the simulation area 3 is located on the base plate 2, a first lighting module 7 and a second lighting module 37 are provided to ensure clear capture of the first and second visual capture modules 8 and 34. Lights are provided at the four corners of the first and second visual capture modules 8 and 34, respectively, to enable visual capture by multiple second visual capture modules 34 and / or the second visual capture modules 34 within the test object's range. In this first embodiment, the second and second visual capture modules 34 both utilize cameras. To achieve optimal capture, a box light strip 71 is positioned around the inner periphery of the box 1 according to the capture requirements. When the simulation area 3 is located on the base plate 2, the first lighting module 7 includes a box light strip 71 surrounding the inner periphery of the box 1, positioned close to the base plate 2. Second lighting modules 37 are evenly distributed across the top and sides of the three-dimensional lifting columns 33 within the simulation area 3, providing light in dark environments. These modules, in conjunction with the camera lights on the first and second visual capture modules 8 and 34, visually capture the test object's real-time posture.

[0077] like Figures 11 to 15 As shown, the telescopic drive mechanism 32 in the first embodiment includes a base 321 fixedly mounted on the base plate 2 and a micro electric telescopic push rod 322 fixedly mounted at a fixed end on the base 321 , and the three-dimensional lifting column 33 and the second visual capture module 34 are installed at the telescopic end of the corresponding micro electric telescopic push rod 322 .

[0078] In the first embodiment, the temperature adjustment module 35 includes an electric heating rod 351 installed in the three-dimensional lifting column 33 and a temperature sensor 352 installed on the three-dimensional lifting column 33; wherein, the three-dimensional lifting column 33 installed with the electric heating rod 351 is not installed with the temperature sensor 352. Specifically, Figure 13 and Figure 14 As shown, some of the three-dimensional lifting columns 33 within the corresponding simulation area 3 are provided with electric heating rods 351, which are evenly distributed in the simulation area 3. Temperature sensors 352 are provided on the tops of the three-dimensional lifting columns 33 adjacent to or not adjacent to the three-dimensional lifting columns 33 with the electric heating rods 351, which are evenly distributed in the simulation area 3. The heating time and the insulation time of the electric heating rods 351 are controlled in real time according to the detection values ​​and experimental requirements.

[0079] like Figure 2 and Figure 3 As shown, foaming mechanisms are provided in the simulation area 3 and on the surface of the bottom plate 2. The foaming mechanisms here use foaming machines, which are evenly distributed in the simulation area 3. Of course, in order to ensure the accuracy of the simulation, foaming machines can also be evenly arranged on the inner surface of the bottom plate 2. Bubbles of different rates, densities and sizes are output through the air outlet at the top of the foaming machine to simulate seabed bubbles, which are used to study the cavitation corrosion of bubbles on the test object.

[0080] In this embodiment, the water depth pressure simulation mechanism 5 adopts a booster, and the wave-making mechanism 4 adopts a wave-making pump. The booster and the wave-making pump are located on the same vertical surface. The booster is located at the lower right of the wave-making pump and above the box light strip 71 to simulate different water depth pressures.

A wave pump is installed on the housing 1 and connected to the housing 1 via multiple bolts. After the simulation experiment is completed, the water outlet screw 102 is opened to drain the water from the tank.

In this embodiment 1, the use of articulated bearings enables the pitch angle adjustment of the fan 652. By adjusting the pitch angle of the fan 652, the actual direction of the sea breeze can be simulated. By adjusting the travel of the fan 652 mounted on the travel guide 63, the blowing distance of the sea breeze can be simulated, providing different working environments for the test object, and facilitating the improvement and optimization of the test object.

[0083] The experimental device of the first embodiment of the present invention also includes a salinity adjustment component 9, which includes a salinity regulator 91 installed above the housing 1, a four-way salt pipe 92 connected to the output port of the salinity regulator 91, and a salinity detector 93 installed on the bottom plate 2; one end of the four-way salt pipe 92 is connected to the output port of the salinity regulator 91, and the other three ends extend to the water inlet end of the wave-making mechanism 4. Specifically, a salinity detector 93 is provided on the inner surface of the bottom plate 2, and a salinity regulator 91 is provided on the top of the housing 1. The salinity regulator 91 is connected to the wave-making pump via a four-way salt pipe 92, and the four-way salt pipe 92 is connected to the water inlet end of the wave-making pump. The salinity regulator 91 detects the obtained salinity through the salinity detector 93, and a salt solution of appropriate proportion is prepared and input into the water tank through the wave-making pump.

[0084] Based on the method of using the experimental device of the above embodiment 1, Figure 20 As shown, the following steps are included:

[0085] Step 1: Adjust the heights of the three-dimensional lifting columns 33 in each simulation area 3 to form the desired ocean floor landform;

[0086] Step 2: Pour water into the box 1, adjust the temperature of the water in the box 1 through the temperature adjustment modules 35, and adjust the salinity of the water in the box 1 through the salinity adjustment component 9;

[0087] Step 3: forming ocean waves of a preset speed and waveform through the wave-making mechanism 4;

[0089] Step 5: Set the foaming mechanism in each simulation area 3 to control the bubble rate, density and size of the output bubbles;

[0090] Step 6: Adjust the output pressure of the boost mechanism to simulate the test object in different water depths;

[0091] Step 7: Place the simulated test object into the water in the box 1 and perform the operation;

[0093] Step 9: After the test is completed, the test object is drained, the drainage component 10 is opened to drain the water in the box 1, and the next test process is awaited.

[0094] Among them, in this embodiment 1, when multiple simulation areas 3 are set on the base plate 2, the multiple simulation areas 3 are set with different terrains. When one test object is working, the influence of terrain turbulence on the working state of the test object is studied. When multiple test objects work in a team, the influence of terrain turbulence and track turbulence on the working state of the test object is studied.

[0095] Combine Figure 21 The test object can move around or through the area of ​​the base plate 2 of the present invention along the route shown, or move horizontally or vertically within the area. The track map route can be combined with Figure 21 The routes shown generate multiple motion routes, and the four areas of the control base plate 2 form different terrains. One or more test subjects can enter the area to work. When one test subject is working, the influence of terrain turbulence on the working state of the test subject is studied. When multiple test subjects work in a team, the influence of terrain turbulence and track turbulence on the working state of the test subject is studied. Figure 22 Note that the triangular area shows a plain landform, and the hexagonal area shows a ridge landform. When the test object passes through this landform area along the track map, it can choose to bypass the hexagonal area and the triangular area, or go straight through the hexagonal area and the triangular area, or choose to cross the two methods. Through various passing methods, the impact of various terrain turbulence on the test object can be studied. The test object is visually captured by the first visual capture module 8 and the second visual capture module 34 set on the three-dimensional lifting column 33 in the area, the inner surface of the box 1, and the surface of the bottom plate 2. The impact of temperature and speed in various environments on the motion state and hovering posture of the test object can be studied.

[0096] The specific operation process of this embodiment 1 in actual operation is as follows: First, the required working environment conditions of the test object are determined. Based on the required conditions, the three-dimensional lifting columns 33 in the bottom plate area 2 are controlled by micro-motor push rods to form the desired ocean floor topography. The water tank is filled with an appropriate amount of water based on the required working environment conditions of the test object. The salinity and temperature of the water are adjusted in real time by the electric heating rod 351 and the salinity regulator 91 according to the required simulated environmental conditions. A wave pump is used to generate waves with the required speed and waveform. By controlling the speed and pitch angle of the top fan 652 and the travel of the fan mounting body 651 on the travel guide 63, a sea breeze with the required direction and range is generated for the test object, thereby affecting the velocity of the fluid in the underwater test object's environment. Depending on the required sea breeze range, the two sets of fans 652 can be operated in one or both groups. The bubble generators located in the control area and on the surface of the bottom plate 2 are used to control the bubble output rate, bubble density, and bubble size of the bubbles. The booster is adjusted to simulate different pressures to place the test object at different water depths. The test subject is placed underwater to perform work. Cameras installed in various areas of the bottom, on the inner surface of the housing 1, and on the surface of the bottom plate 2 are used to visually capture the test subject's real-time posture. A three-dimensional image of the test subject and its forward speed are observed and recorded. The housing light strip 71 and the illuminator provide light in dark environments, assisting in visually capturing the test subject's real-time posture. A three-dimensional image of the test subject and its forward speed are observed and recorded. The salinity meter 93 and temperature sensor 352 record the salinity and temperature of the test subject's underwater working environment. After completing work in the designated area and recording data, the test subject is removed from the water. The water outlet screw 102 is opened to drain the liquid inside the housing 1 through the drain hole. This first embodiment allows the three-dimensional lifting column 33, salinity regulator 91, electric heating rod 351, wave-making pump, and fan 652 to simulate different working conditions according to actual work needs, allowing the test subject to operate in simulated environments with different underwater conditions and conduct experiments. Moreover, when the multiple simulation areas 3 are adjusted to present different landforms through the corresponding telescopic drive mechanisms 32, the track of the test object can be planned in multiple options, and the influence of various terrain turbulences on the test object can be studied. At the same time, the influence of track turbulence on the working state of the test object can also be studied, further ensuring the adaptability of the simulation device of the present invention to the actual marine environment and the comprehensiveness of detection.

[0097] Example 2

[0098] like Figure 23 As shown, the difference between the second embodiment and the first embodiment is that the four simulation areas 3 are relatively arranged on the two sides of the box body 1, as shown in FIG. Figure 11As shown, the three-dimensional lifting column 33 in the simulation area 3 on the side of the box body 1 is arranged in the same manner as in the first embodiment, and is equipped with a temperature sensor 352, an electric heating rod 351, etc., and a foaming machine is also installed in the simulation area 3 and on the polygonal sunken surface 31 in the simulation area 3 and on the inner surface of the bottom plate 2. It should be noted that in this second embodiment, when the simulation area 3 is set on the side wall of the box body 1, the first lighting module 7 includes a box light belt 71 arranged around the inner periphery of the box body 1; the box light belt 71 is set between two adjacent simulation areas 3 in the vertical direction, and the box light belt 7125 needs to be adjusted to the adjacent position as required. Figure 11 Position shown.

[0099] The actual use process of this second embodiment is as follows: First, the required working environment conditions of the test object are determined. The three-dimensional lifting columns 33 in the simulation area 3 on the side of the box body 1 are controlled by micro-motor push rods to form the required ocean floor landforms according to the required conditions. The water tank is filled with an appropriate amount of water according to the required working environment conditions of the test object. The salinity and temperature of the water are adjusted to the required simulation conditions by the electric heating rod 351 and salinity regulator 91 according to the required simulation conditions. A wave pump is used to generate ocean waves with the required speed and waveform. The speed and pitch angle of the top fan 652 and the travel of the fan mounting body 651 on the travel guide 63 are controlled to generate the sea breeze with the required direction and range for the test object to work. Depending on the required sea breeze range, the two sets of fans 652 can be selected to operate one or both, thereby affecting the speed of the fluid in the test object's environment. The bubble generator installed in the control area and on the surface of the bottom plate 2 controls the bubble output rate, bubble density, and bubble size of the bubbles output by the air outlet. The supercharger is adjusted to simulate different pressures to place the test object in different water depths. The test object is placed underwater to work. The cameras installed in various areas of the bottom, the inner surface of the box 1, and the surface of the bottom plate 2 are used to visually capture the real-time posture of the test object, and observe and record the three-dimensional image and forward speed of the test object as it passes. In this embodiment 2, the corresponding height of the box light strip 71 is adjusted. The lighting lamps in the first embodiment remain unchanged in the second embodiment and are also installed on the top of the three-dimensional lifting column 33 and evenly distributed in the area. The box light strip 71 and the lighting lamps provide light when the environment is dark, and assist the camera lighting to visually capture the real-time posture of the test object, observe and record the three-dimensional image and forward speed of the test object as it passes. The salinity detector 93 and temperature sensor 352 are used to record the salinity and temperature of the test object in the underwater working environment. After completing the work and data recording in the set area, the test object is taken out of the water, and the water outlet screw 102 is opened to drain the liquid inside the box 1 through the drain hole, waiting for the next test process to start.

[0100] Combining Examples 1 and 2, the present invention cleverly uses miniature electric push rods to control a three-dimensional lifting column 33, simulating complex ocean floor topography in multiple simulation areas 3. This provides test subjects with different working environments and is used to evaluate their service performance in complex marine environments. Cameras are installed on the outer surface of the three-dimensional lifting column 33, the inner surface of the housing 1, and the surface of the bottom plate 2. When the test subject is operating at the bottom, multiple first and second visual capture modules 8 and 3D cameras within the test subject's range capture its posture in real time, generating a 3D view of the test subject and its motion state at different moments. Wave-generating mechanisms 4 generate waves of varying speeds to study the effects of different working environments on the test subject's working and hovering postures. The pitch angle of the fan 652 is adjusted to simulate actual sea breeze direction, and the travel of the fan mount 651 on the travel guide 63 is adjusted to simulate the wind's travel range. This provides the test subject with different working environments and facilitates test subject improvement and optimization. A foaming machine is installed on the bottom plate 2 or housing 1 to simulate seabed bubbles, enabling the study of cavitation corrosion caused by bubbles on the test subject. The boost mechanism is designed to simulate pressure at varying depths. The present invention incorporates a salinity detector 93 and a temperature sensor 352. Based on the salinity and temperature detected, the heating and holding times of the electric heating rod 351 are adjustable. The prepared salt solution is then fed into the water tank via the salinity adjustment assembly 9 and the wave-making mechanism 4, controlling the tank's salinity and temperature. The present experimental device decouples the complex marine environment into multiple factors: complex topography, ambient temperature, seawater flow rate, wind direction and range, water depth, pressure, and salt spray corrosion. Through structural design, this coupled simulation achieves comprehensive, accurate, and controllable simulation of the marine service environment.

[0101] It should be understood that the specific embodiments described above are only used to explain the present invention and are not intended to limit the present invention. Obvious changes or modifications derived from the spirit of the present invention are still within the scope of protection of the present invention.
