Description

Technical Field

[0001] The utility model relates to the technical field of ocean internal wave measurement, in particular to an ocean simulation environment wave parameter measurement device for a laboratory. Background Art

[0002] As a crucial phenomenon in the ocean, internal waves not only play a key role in transferring energy from the upper ocean to the deeper layers, but also carry nutrient-rich cold water from the deep to the warmer shallow layers, profoundly impacting mass distribution, momentum transfer, and energy exchange processes in the ocean. Accurately measuring and understanding the characteristics of internal waves is crucial for revealing the internal dynamics of the ocean, ensuring marine engineering safety, and promoting the development of marine resources. In particular, in the field of marine engineering, real-time monitoring and early warning of internal waves can effectively prevent threats to the stability of structures such as semi-submersible platforms and anchored oil facilities, ensuring the smooth progress of offshore operations such as drilling and riser installation.

[0003] Given the complexity of ocean internal wave research and the challenges of field measurements, the development of ocean internal wave measurement simulation equipment suitable for laboratory environments is particularly necessary. Laboratory simulation not only provides controllable experimental conditions, facilitating repeated verification and precise parameter adjustment, but also effectively reduces research costs and accelerates the transition from theory to application. By using simulation equipment to modify the wave environment in laboratory tanks, researchers can conduct in-depth research on the mechanisms of internal wave generation, propagation, and interaction with marine structures in a safe and efficient environment, providing a scientific basis for marine engineering design and improving early warning capabilities for catastrophic internal waves.

[0004] Patent publication number CN101441077A describes a floating platform-based ocean internal wave measurement system. This system utilizes a CTD (temperature, salinity, and depth) sensor in conjunction with a motor, a retractable net, and mooring lines to achieve detection at varying depths. However, this system is designed for field operation. Its complex mechanical structure and bulky auxiliary equipment (such as the retractable net and mooring lines) not only limit its portability and flexibility in laboratory settings but also increase operational difficulty and maintenance costs. Furthermore, the system lacks stability in water and is susceptible to current impact. Especially in dynamically changing wave environments, strong current impact not only physically disturbs the measurement equipment, resulting in unstable data acquisition, but can also cause sensor displacement or damage, further reducing the accuracy and reliability of measurement results.

[0005] Therefore, developing an ocean internal wave measurement device that is simple in structure, portable, suitable for laboratory simulation environments, and can effectively resist water flow impact and maintain measurement stability is a technical problem that needs to be solved urgently. Utility Model Content

[0006] The utility model provides a laboratory-use ocean simulation environment wave parameter measurement device, aiming to solve the problems raised in the background art, such as the complexity of the overall device, the need to carry a retractable vehicle and a mooring rope when in use, and the lack of stability after the device is submerged in water, which easily leads to inaccurate data.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a laboratory-use ocean simulation environment wave parameter measurement device, the laboratory-use ocean simulation environment wave parameter measurement device comprises a pressure-resistant cabin, a control component fixedly mounted on the inside of the pressure-resistant cabin, a protective component fixedly mounted on the outside of the pressure-resistant cabin, and a counterweight component fixedly connected to the bottom of the pressure-resistant cabin; the control component comprises a circuit board fixedly arranged inside the pressure-resistant cabin, a controller fixedly mounted on the circuit board, a battery pack for supplying power to the circuit board, and a battery fixedly arranged on the top of the pressure-resistant cabin and connected to the controller The sensor group is connected; the protective component includes a float wrapped around the outside of the pressure-resistant cabin, a plurality of lightweight fins arranged along the circumference of the float, and a protective strip fixedly connected between two adjacent fins and distributed in an arc shape along the outside of the lightweight fin; the counterweight component includes a fixed cylinder fixedly connected to the bottom of the pressure-resistant cabin and with an opening at the bottom, a light rod fixedly connected to the top of the inner side of the fixed cylinder and arranged axially along the fixed cylinder, a plurality of standard blocks sleeved on the outer wall of the light rod, and a separation device fixedly mounted on the fixed cylinder; the standard blocks inside the fixed cylinder can be separated one by one by the separation device.

[0008] When in use, the device is placed in the water. The pressure-resistant cabin has excellent pressure resistance and can meet the pressure resistance requirements of the device. The protective assembly can prevent solid garbage in the ocean from damaging the equipment through the combination of lightweight fins and protective strips, and is used in conjunction with the buoy and counterweight assembly to balance the overall weight of the device, so that the device can float in the seawater without sinking to the bottom. The standard blocks on the inside of the fixed cylinder can be quickly separated one by one through the separation device, ensuring that the weight of the equipment is reduced while the volume remains unchanged, so that the equipment can float up a certain distance, thereby being able to measure parameters such as the wave height and temperature of internal waves at different depths of the ocean from bottom to top.

[0009] Preferably, the separation device includes a mounting seat fixed to the outer wall of the fixed cylinder along the circumferential direction, a gear rotatably connected to the inner side of the mounting seat, a grab rod fixedly connected to the bottom of the gear, a plurality of mounting grooves distributed along the circumferential direction and opened on the outer wall of the fixed cylinder, a cylinder fixedly mounted on the inner side of the mounting groove and connected to the output end of the controller, a moving block fixedly connected to the output end of the cylinder, and a rack fixedly connected to one side of the moving block and meshing with the gear.

[0012] Preferably, the outer side of each standard block is slidably connected to the inner wall of the fixed cylinder, and a protruding portion integrally connected thereto is provided at the center of the top of the standard block.

[0013] Preferably, the protection assembly further includes a guide ring fixedly mounted on the outside of the buoy and symmetrically distributed up and down.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] The present invention provides a laboratory-use ocean simulation environment wave parameter measurement device with a simple structure and convenient use. When the device encounters a single-sided or multi-sided impact force of a water flow, the device cuts the impacting water flow horizontally and vertically through lightweight fins and protective strips, thereby fully weakening the impact force. Since the center of gravity of the device is biased downward, the device can maintain its verticality while suspended in the water, preventing the device from flipping or violently shaking due to the impact of the water flow when sinking or floating in the water. The pressure-resistant cabin has excellent pressure resistance, which can meet the pressure resistance requirements of the device. Moreover, the protective assembly can prevent solid garbage or organisms in the ocean from damaging the device through the lightweight fins and protective strips. The buoy and counterweight assembly are used to balance the overall weight of the device, allowing the device to float in the seawater without sinking. The standard blocks inside the fixed cylinder can be quickly separated one by one by a separation device, ensuring that the weight of the device is reduced while the volume remains unchanged, allowing the device to float upward a certain distance, thereby measuring parameters such as wave height and temperature of internal ocean waves at different depths in a laboratory ocean simulation environment.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0028] This embodiment provides a laboratory ocean simulation environment wave parameter measurement device, such as Figures 1 to 4As shown, the laboratory ocean simulation environment wave parameter measurement equipment includes a pressure-resistant cabin 1, a control component 2 fixedly installed on the inner side of the pressure-resistant cabin 1, a protective component 3 fixedly installed on the outer side of the pressure-resistant cabin 1, and a counterweight component 4 fixedly connected to the bottom of the pressure-resistant cabin 1; the control component 2 includes a circuit board 2-1 fixedly arranged inside the pressure-resistant cabin 1, a controller 2-3 fixedly mounted on the circuit board 2-1, a battery pack 2-4 for supplying power to the circuit board 2-1, and a sensor group 2-2 fixedly arranged on the top of the pressure-resistant cabin 1 and connected to the controller 2-3; the protective component 3 includes a buoy 3-1 wrapped around the outside of the pressure-resistant cabin 1, a plurality of lightweight fins 3-2 arranged along the circumference of the buoy 3-1, and a protective strip 3-3 fixedly connected between two adjacent fins 3-2 and distributed in an arc shape along the outside of the lightweight fin 3-2; the counterweight assembly 4 includes a fixed cylinder 4-1 fixedly connected to the bottom of the pressure-resistant cabin 1 and with an open bottom, a light rod 4-2 fixedly connected to the inner top of the fixed cylinder 4-1 and arranged axially along the fixed cylinder 4-1, a plurality of standard blocks 4-3 sleeved on the outer wall of the light rod 4-2, and a separation device 4-4 fixedly installed on the fixed cylinder 4-1.

[0029] When in use, the device is placed in a water body simulating an ocean environment. The pressure-resistant cabin 1 has excellent pressure resistance and can meet the pressure resistance of the device. The protective component 3 can prevent solid garbage or organisms in the ocean from damaging the device through the cooperation of the lightweight fins 3-2 and the protective strips 3-3. In addition, the buoy 3-1 and the counterweight component 4 are used to balance the overall weight of the device, so that the device can float in the seawater without sinking. When the device encounters a single-sided or multi-sided impact force of the water flow, the lightweight fins 3-2 and the protective strips 3-3 are used to respectively cross the impacting water flow. The horizontal and vertical cuts allow the divided water flow to flow along the surface of buoy 3-1, thereby fully weakening the impact force. Since the center of gravity of the device is biased downward, it can maintain the verticality of the device suspended in the water, preventing the device from flipping or violently shaking due to the impact of the water flow when it sinks and floats in the water. The standard blocks 4-3 inside the fixed cylinder 4-1 can be quickly separated one by one by the separation device 4-4, ensuring that the weight of the device is reduced while the volume remains unchanged, allowing the device to float upward a certain distance, thereby measuring parameters such as wave height and temperature of internal ocean waves at different depths from bottom to top. However, due to the limited depth of the laboratory simulation environment, the separated standard blocks 4-3 will quickly sink to the bottom of the simulated ocean environment. Later, they can be salvaged and collected for convenient recycling.

[0030] In one embodiment, the separation device 4-4 includes a mounting seat 4-4-1 fixed to the outer wall of the fixed cylinder 1 along the circumferential direction, a gear 4-4-2 rotatably connected to the inner side of the mounting seat 4-4-1, a grab bar 4-4-3 fixedly connected to the bottom of the gear 4-4-2, a plurality of mounting grooves 4-4-4 distributed along the circumferential direction and opened on the outer wall of the fixed cylinder 4-1, a cylinder 4-4-5 fixedly mounted on the inner side of the mounting groove 4-4-4 and connected to the output end of the controller 2-3, a moving block 4-4-6 fixedly connected to the output end of the cylinder 4-4-5, and a rack 4-4-7 fixedly connected to one side of the moving block 4-4-6 and meshingly connected to the gear 4-4-2.

[0031] In this embodiment, referring to Figure 2 and Figure 3 , the cylinder 4-4-5 drives the moving block 4-4-6 to move downward, the moving block 4-4-6 drives the rack 4-4-7 to move, the rack 4-4-7 drives the gear 4-4-2 to rotate, and the gear 4-4-2 then drives the grab bar 4-4-3 to open, thereby separating the bottom standard block 4-3. When the piston rod of the cylinder 4-4-5 is reset, it holds the standard block 4-3, and the standard block 4-3 always blocks the bottom of the fixed cylinder 4-1, achieving the effect of reducing its own weight while keeping the buoyancy unchanged, thereby increasing the height of the equipment in the water.

[0032] In one embodiment, the bottom of the fixed cylinder 4-1 is provided with grooves 4-1-1 distributed at equal intervals along the circumferential direction, the inner side of the groove 4-1-1 is hinged with an L-shaped limit piece 4-4-8, the middle part of the grab bar 4-4-3 is provided with a square hole 4-4-9, the square hole 4-4-9 is hinged with a connecting rod 4-4-10, the upper end of the connecting rod 4-4-10 is hinged to the square hole 4-4-9, and the lower end is hinged to the L-shaped limit piece 4-4-8.

[0033] In this embodiment, referring to Figure 2 and Figure 3 When the grab bar 4-4-3 is opened, it moves the connecting rod 4-4-10, which then drives the L-shaped limiter 4-4-8 to lift the standard block 4-3 that has fallen from the upper layer. When the grab bar 4-4-3 is closed, the grab bar 4-4-3 drives the connecting rod 4-4-10 to move, and the connecting rod 4-4-10 moves downward.

[0034] In one embodiment, the sensor group 2-2 includes a column 2-2-1 plugged into the top of the pressure-resistant cabin 1, a depth sensor 2-2-2, a wave height sensor 2-2-3 and a temperature sensor 2-2-4 embedded in the inner side of the column 2-2-1 from top to bottom and connected to the controller 2-3, and a sealing ring 5 is fixedly installed between the lower end of the column 2-2-1 and the top of the pressure-resistant cabin 1.

[0035] In this embodiment, referring to Figure 2 When the device is working, the depth sensor 2-2-2 monitors the specific depth of the device, the wave height sensor 2-2-3 monitors the wave height parameters of the internal waves, and the temperature sensor 2-2-4 detects the internal temperature, and then transmits the electrical signal to the controller 2-3. After the measurement is completed, the controller 2-3 starts the separation device 4-4 to separate part of the standard block 4-3 until the device floats upward. The sealing ring 5 can prevent water seepage, effectively improving the safety of the equipment.

[0036] In one embodiment, each of the standard blocks 4 - 3 is slidably connected to the inner wall of the fixed cylinder 4 - 1 , and a protrusion integrally connected thereto is provided at the center of the top of the standard block 4 - 3 .

[0037] In this embodiment, referring to Figure 2 and Figure 3 The adjacent two standard blocks 4-3 are separated by a certain distance through the protrusion, so that when a single standard block 4-3 is separated, it can be ensured that the previous standard block 4-3 can fall down under the toggle of the L-shaped limiter 4-4-8 and fill the vacant position.

[0038] In one embodiment, the standard block 4 - 3 is made of calcium carbonate material that is cut into a cylindrical shape and has a hole in the center.

[0039] In this embodiment, referring to Figure 2 The standard block 4-3 is a cylindrical block made of calcium carbonate, which is easy to process and has low cost, and will not cause pollution to the simulated marine environment. Example 2

[0040] Different from Example 1, the protection assembly 3 also includes a guide ring 3-4 fixedly installed on the outside of the buoy 3-1 and symmetrically distributed up and down.

[0041] In this embodiment, referring to Figure 4 The guide ring 3-4 can disperse the unilateral impact force of the water flow to maintain the verticality of the device suspended in the water and prevent the device from flipping or shaking violently due to the impact of the water flow when it sinks or floats in the water.

[0042] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
