Description

Technical Field

[0001] This utility model provides a mobile platform for measuring ice flow, thickness, and depth, belonging to the field of hydrological measurement technology. Background Technology

[0002] Polar acoustics is one of the three major research directions in underwater acoustics. In winter, ice-covered areas are covered by thick ice layers, and sound waves interact with the ice during propagation, creating a unique underwater acoustic propagation environment. Researching underwater acoustic signal processing methods and equipment adapted to ice-covered environments is one of the important topics for Arctic underwater acoustic researchers in my country.

[0003] Monitoring subglacial hydrological information using acoustic methods has significant scientific and applied value, especially in polar or high-altitude regions. Traditional methods for acquiring subglacial hydrological information typically rely on manually drilling large-diameter holes in the ice surface and placing sensor equipment underwater to collect data. This method is not only cumbersome and inefficient but also carries numerous potential risks. Drilling ice holes consumes substantial manpower, resources, and time, and may also lead to cracks and collapses due to the unstable ice structure, causing serious consequences such as equipment damage or even personal injury, increasing the uncertainty and cost of the experiment.

[0004] Therefore, there is an urgent need to develop a new type of cross-ice acoustic monitoring device suitable for ice-covered environments, capable of efficiently and accurately collecting sub-ice hydrological information without damaging the ice structure. This type of device should be portable, miniaturized, and modular, adaptable to various complex ice surface terrains, easy to operate and deploy quickly, and possess excellent data processing and wireless transmission capabilities to achieve standardization, automation, and repeatability of the measurement process. Utility Model Content

[0005] To address the aforementioned technical problems, the purpose of this utility model is to propose a novel mobile platform for measuring flow, thickness, and depth across ice layers to solve the problem of detecting hydrological information across ice layers.

[0006] The specific technical solution is as follows:

[0007] A mobile platform for measuring ice flow, thickness and depth includes a trolley, on which an angle controller is installed. An ice thickness and water depth measuring transducer and a flow velocity measuring transducer are respectively installed on a lifting device. A heating device is provided at the bottom of the lifting device.

[0008] The lifting device for the ice thickness and water depth measuring transducer is directly mounted on the trolley, while the lifting device for the flow velocity measuring transducer is mounted on the angle controller.

[0009] A leveling device is installed on the bottom of the vehicle.

[0010] The lifting device includes an outer tube, a base plate at the bottom of the outer tube, and a heating device installed on the base plate; a main lifting plate at the top of the outer tube, which is connected to the main lifting guide rod by a thread to achieve lifting.

[0011] The outer tube has a transducer mounting plate inside, which is used to install ice thickness and water depth measurement transducers and flow velocity measurement transducers; the mounting plate is fixedly connected to the secondary lifting plate, and the secondary lifting plate is raised and lowered by connecting the secondary lifting guide rod through a thread.

[0012] This invention supports continuous multi-point rapid measurement, is suitable for large-scale ice surface operations, and is used for water area surveying and data collection, effectively improving operational efficiency. Attached Figure Description

[0014] Figure 2 This is a schematic diagram of the lifting device structure of this utility model. Detailed Implementation

[0015] The specific technical solution of this utility model is described in conjunction with the accompanying drawings.

[0016] like Figure 1 As shown, a mobile platform for measuring ice flow, thickness and depth includes a trolley 6, an angle controller 5 is installed on the trolley 6, an ice thickness and water depth measuring transducer 1 and a flow velocity measuring transducer 2 are respectively installed on a lifting device 3, and a heating device 4 is provided at the bottom of the lifting device 3.

[0017] The lifting device 3, where the ice thickness and water depth measuring transducer 1 is located, is directly installed on the trolley 6, and the lifting device 3, where the flow velocity measuring transducer 2 is located, is installed on the angle controller 5.

[0018] A leveling device is installed on the bottom surface of the car 6.

[0019] like Figure 2 As shown, the lifting device 3 includes an outer tube 37, a base plate 35 at the bottom of the outer tube 37, and a heating device 4 installed on the base plate 35; a main lifting plate 33 is provided at the top of the outer tube 37, and the main lifting plate 33 is connected to the main lifting guide rod 31 by a thread to achieve lifting.

[0020] The outer tube 37 has a transducer mounting plate 36 inside, which is used to install the ice thickness and water depth measuring transducer 1 and the flow velocity measuring transducer 2. The mounting plate 36 is fixedly connected to the secondary lifting plate 34, which is raised and lowered by a secondary lifting guide rod 32 connected by threads. Both the main lifting guide rod 31 and the secondary lifting guide rod 32 are driven by electrodes.

[0021] This invention is applicable to river ice areas with ice thickness greater than 0.1m. The system uses a portable trolley 6 to perform multi-point measurements and has the following functions and structural requirements: a heating device 4 is installed at the lower end of the lifting device 3 to locally melt the ice surface, facilitating sensor coupling with the water; the trolley 6 is equipped with two sets of lifting devices 3, one for vertical lifting and the other for inclined lifting at a 30-degree angle to the bottom of the trolley. The trolley 6 is lightweight, detachable, and mobile, making it easy for a single person to carry and for multi-point deployment.

[0022] Transducer dimensions: 93mm in length, 56mm in width, weight (excluding cable): 0.4kg.

[0023] The specific usage method is as follows:

[0024] 1. Site Preparation: Transport the mobile ice-crossing flow, thickness, and depth measurement platform to the target area on the ice surface, selecting a relatively flat area without obvious cracks or obstacles as the measurement point. Power on the equipment and check whether each subsystem is operating normally, performing necessary system self-checks to ensure the equipment is in good working condition.

[0025] 2. Equipment Securing: Securely place the mobile platform equipped with ice-crossing flow, thickness, and depth measurement devices at the selected ice surface measurement points. Adjust the height and angle of the leveling device to ensure the entire equipment remains horizontal, preventing tilting or wobbling that could affect subsequent measurement accuracy. If necessary, use anti-slip devices to enhance the equipment's stability on the ice surface.

[0026] 3. Lowering the lifting device 3 and preheating the ice surface: Using the display, operate the stepper motor to rotate the main lifting guide rod 31, then lower the main lifting plate 33 until the lower end of the outer tube 37 contacts the ice surface with the heating device 4. Start the heating device 4 system on the display; electric heating rapidly melts the ice in the contact area, forming a small water film, thus creating a favorable acoustic coupling environment for sound wave propagation. During the heating process, monitor temperature changes in real time to prevent overheating from damaging the equipment or the ice structure.

[0027] 4. Transducer Coupling: After a water film forms on the localized ice surface, the stepper motor, controlled by the display screen, rotates the secondary lifting guide rod 32. This causes the secondary lifting plate 34 to slowly lower, carrying the ice thickness and water depth measuring transducer 1 and the flow velocity measuring transducer 2, into the melting zone, ensuring full contact with the water film and forming a stable acoustic channel. This state is maintained for several seconds to confirm that the ice thickness and water depth measuring transducer 1 and the flow velocity measuring transducer 2 are effectively coupled to the ice surface and in a fixed position. Subsequently, the system automatically completes acoustic matching adjustment and enters the test-ready state.

[0028] 5. Start the measurement process: Press the measurement start button on the control terminal, and the system will sequentially activate ice thickness and water depth measuring transducer 1. The device sends an acoustic signal and receives the echo, calculating the water depth and ice thickness data based on the signal propagation time and the speed of sound in the medium. The measurement results will be displayed in real time on the main control terminal screen. Subsequently, the system switches to flow velocity measuring transducer 2 and starts the flow velocity transducer. Using the Doppler principle or other velocity measurement algorithms, the current water flow velocity at the measuring point is measured, and the result is displayed on the control terminal, completing a full multi-parameter detection task.

[0029] 6. Equipment Recovery: After the measurement is completed, restart the heating device 4 to melt the ice contact area again, allowing the ice thickness and water depth measuring transducer 1 and the flow velocity measuring transducer 2 to detach smoothly from the ice. Start the lifting device 3 to rotate the main lifting guide rod 31 and the secondary lifting guide rod 32, smoothly raising the main lifting plate 33, the ice thickness and water depth measuring transducer 1, and the flow velocity measuring transducer 2 to their initial positions, ensuring the equipment is undamaged and unobstructed, ready for transfer to the next measurement point.

[0030] 7. Repeated Measurement: The operator pushes or remotely controls the trolley 6 to move to the next predetermined measurement point and repeats the on-site testing process according to the above steps.
