Description

Technical Field

[0001] This utility model relates to the field of river flow velocity and flow rate detection technology, and in particular to a device for measuring flow velocity and flow rate under ice. Background Technology

[0002] Measuring the subglacial velocity and flow rate of inland rivers during winter is an extremely challenging task, as the river surface is covered by a thick layer of ice. Currently, the conventional method is to manually drill holes in the ice and then lower flow measurement equipment such as flow meters or acoustic Doppler current profilers (ADCP) to obtain subglacial velocity data. However, to complete a comprehensive measurement of a cross-section, multiple holes need to be drilled in the ice. This process not only consumes a lot of manpower and resources, but also results in asynchronous data collection at different measurement points, leading to a certain deviation between the measurement results and the actual values.

[0024] Reference Figure 1 -3. This utility model provides a device for measuring the velocity and flow rate under ice, comprising:

[0025] The measuring unit 100 includes a sealed box 101. A solar panel 102 is fixedly connected to the upper end of the sealed box 101. A battery 103 is fixedly connected to one side of the interior of the sealed box 101. A control box 104 is fixedly connected to the other side of the interior of the sealed box 101. A storage device 105 is fixedly connected to the inner bottom wall of the sealed box 101. A measuring rod 108 is fixedly connected to the lower surface of the sealed box 101. An ice-based acoustic transducer 109 is fixedly connected to the lower end of the measuring rod 108. A fixing component 110 is provided on the outer surface of the measuring rod 108. The battery 103 works in conjunction with the solar panel 102 to store energy collected during the day, ensuring continuous power support for the system even without sunlight. The control cabinet 104 houses several key components responsible for data processing, analysis, and communication with external remote control systems. The storage unit 105 provides a large-capacity data storage function, ensuring that the device can capture and retain important flow velocity and flow data even when unattended for extended periods, thus providing valuable data for subsequent accurate analysis of sub-ice flow motion. The measuring rod 108 allows the sub-ice acoustic transducer 109 to be stably immersed in the water, providing an ideal sensing position for measuring the flow velocity and flow of sub-ice water. The sub-ice acoustic transducer 109 effectively captures and converts sound wave information, thereby providing accurate motion data. The fixing component 110 securely fixes the device at the target measurement position, ensuring that the device is not affected by the impact of ice flow and water flow during the measurement process, improving the accuracy and reliability of the measurement data.

[0026] A signal transmitter 106 is fixedly connected to one side of the upper surface of the storage device 105, and a locator 107 is fixedly connected to the other side of the upper surface of the storage device 105. Both the signal transmitter 106 and the locator 107 are electrically connected inside the control housing 104. The storage device 105 is electrically connected to the control housing 104, and the under-ice acoustic transducer 109 is electrically connected inside the control housing 104. The solar panel 102 is electrically connected to the battery 103, and the battery 103 is electrically connected to both the control housing 104 and the under-ice acoustic transducer 109. The measured data is transmitted in real time or periodically to the monitoring center on shore or far from the measurement site via the signal transmitter 106, improving the real-time nature of the data and the efficiency of on-site monitoring. The efficient operation of the signal transmitter 106 ensures reliable data transmission in extreme environments, supporting rapid response and decision-making by the ground station and command center. The addition of the locator 107 enables the device to have precise positioning capabilities, which can help users determine the specific location of the device. This not only helps with subsequent equipment maintenance and retrieval but also provides a precise geographical location background for data analysis, improving the relevance and scientific nature of the research. The solar panel 102 and the battery 103 can provide stable power support.

[0027] Furthermore, the fixing assembly 110 includes a fixing plate 110a and an extension rod 110e. A sleeve 110b is fixedly connected inside the fixing plate 110a, and the sleeve 110b is slidably connected to the outer surface of the measuring rod 108. Threaded pins 110c are threadedly connected to both sides of the upper surface of the fixing plate 110a. The upper end of the extension rod 110e is fixedly connected to the lower end of the under-ice acoustic transducer 109, and a conical spike disc 110f is fixedly connected to the lower end of the extension rod 110e. A rotating handle 110d is fixedly connected to the upper end of the threaded pin 110c. The fixing plate 110a is arranged in a cross shape, and multiple conical pins are provided on the lower surface of the conical spike disc 110f. The cross-shaped arrangement of the fixing plate 110a increases its coverage area and structural stability, effectively coping with complex and ever-changing ice environments. The sliding connection between the sleeve 110b and the measuring rod 108 provides the system with a certain degree of flexibility, facilitating the adjustment and calibration of the depth and position of the measuring rod 108 to adapt to different measurement needs. The design of the threaded nail 110c and the rotating handle 110d makes the installation and disassembly of the fixing plate 110a more convenient, reducing the complexity and time consumption of on-site operations. The combined structure of the extension rod 110e and the cone-shaped spike plate 110f ensures that the acoustic transducer 109 under the ice can be firmly implanted into the riverbed, improving the stability of the equipment and facilitating its use.

[0028] During use, 2-6 devices are first set up at a certain location. The devices are then nailed to the ice surface using fixing plates 110a and threaded nails 110c. The cone-shaped spikes 110f can be used to anchor the devices in the riverbed, thereby improving their stability. Each base station device independently sends coded acoustic signals. Each station receives acoustic signals sent by other stations and measures the bidirectional propagation time of the acoustic waves between each pair of stations. The signals sent and received by the acoustic transducer 109 under the ice are transmitted back to the control box 104 and then transmitted out through the signal transmitter 106. Mathematical methods are then used to analyze and invert the flow, calculating the under-ice flow velocity and flow rate of the observed river section. This reduces the workload and allows for real-time monitoring of the river, improving ease of use.

[0029] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
