Description

Technical Field

[0001] This utility model belongs to the field of intelligent detection technology, specifically relating to an ice layer thickness measurement device based on a temperature sensor. Background Technology

[0002] Monitoring ice thickness is a core issue in polar science, climate change research, and ice engineering safety, and its importance is self-evident. Accurately determining ice thickness is not only crucial for understanding the global water cycle and heat balance, but also directly affects ice-covered resource development and shipping safety, making it a key link in promoting the development of related disciplines.

[0003] Currently, methods for measuring ice thickness mainly include mechanical measurement, ultrasonic measurement, and satellite remote sensing. While mechanical measurement is simple, it requires manual operation and carries a high degree of risk. Ultrasonic measurement, although highly accurate, has expensive equipment and is easily affected by environmental factors. Satellite remote sensing, while providing wide-area data, is limited in accuracy by resolution and interference from complex terrain, making it difficult to meet high-precision requirements. These limitations render existing technologies inadequate for monitoring large-scale, high-precision ice thickness. Therefore, a new type of ice thickness measurement device is needed to address the problems of existing technologies. Utility Model Content

[0027] Example 1

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the ice thickness measuring device based on temperature sensors of this utility model includes one or more measuring units connected as one unit. Each measuring unit includes a pipe 1 for placing under the water surface before the water surface freezes or in the ice layer after the water surface freezes, and multiple temperature sensors 2 arranged inside the pipe. The temperature sensors 2 are fixed on the inner wall of the pipe 1, and the gap between the temperature sensors 2 and the pipe 1 is filled with inert material.

[0029] In this embodiment, one end of the pipe 1 is provided with an internal thread, and the other end of the pipe 1 is provided with an external thread. The internal and external threads are matched and a sealing gasket is added to form a threaded structure, thereby connecting the pipes 1 in the two measuring units to achieve the purpose of extending the measuring depth.

[0030] This design allows for the rotational connection of two pipe sections to form a single unit when necessary, thereby extending the measurement depth after the connection line is completed.

[0031] In this embodiment, the multiple temperature sensors 2 adopt a multi-group interleaved structure design to prevent data distortion caused by damage to a single temperature sensor, as well as mutual influence caused by malfunctions of temperature sensors in the same group; the multiple temperature sensors 2 are evenly arranged at equal intervals inside the pipe.

[0032] In practical implementation, the multiple temperature sensors 2 adopt a three-group interleaved structure design, and each group of temperature sensors transmits data via a single bus, uses an independent power line, and each group can operate independently. The multiple temperature sensors 2 are arranged vertically and equidistantly inside the pipe. The first group of temperature sensors 2 is arranged in the order A1, A2, A3, A4..., the second group of temperature sensors 2 is arranged in the order B1, B2, B3, B4..., and the third group of temperature sensors 2 is arranged in the order C1, C2, C3, C4... The spacing between two adjacent temperature sensors 2 can be set between 3mm and 10cm depending on the specific situation. The arrangement order of the multiple temperature sensors 2 is A1, B1, C1, A2, B2, C2, A3, B3, C3, A4, B4, C4..., and so on, until the required length is reached.

[0033] In practice, the number of temperature sensors 2 can be increased or decreased depending on the detection depth and accuracy. Temperature sensors 2 are sealed with a waterproof coating for waterproofing.

[0034] In this embodiment, the temperature sensor 2 is fixed to the inner wall of the pipe 1 using thermally conductive silicone to prevent displacement. Furthermore, the temperature sensor 2 is tightly connected to the inner wall of the pipe, facilitating temperature conduction.

[0035] In this embodiment, the pipe 1 is made of metal, plastic or resin composite material, and is used to achieve waterproofing and support functions.

[0036] In this embodiment, the pipe is made of metal, plastic or resin composite material to achieve waterproofing and support functions; the inert material includes one or more combinations of polyethylene foam material, pulp molding material and synthetic sponge material.

[0037] The inert material filling also serves to prevent temperature conduction along the inside of the pipe.

[0038] In this embodiment, a solar photovoltaic panel 8 is installed on the upper part of the pipe 1.

[0039] In this embodiment, an angle sensor 9 is installed inside the pipe 1 to detect the relative angle between the pipe 1 and the ice surface.

[0040] In specific implementation, the angle sensor 9 includes, but is not limited to, an electronic gyroscope sensor, such as an MPU6050 gyroscope sensor.

[0041] In this embodiment, the top of the pipe 1 is provided with a connection port 3 for the angle sensor 9 and multiple temperature sensors 2 to connect to the external data processing module 5.

[0042] In use, the temperature sensor 2 and the angle sensor 9 are connected to the connection port 3, and then externally connected to the data processing module 5 via the data cable 4. The data processing module 5 is connected to the communication module 6, which transmits the data processed by the data processing module 5 to the remote receiving device in real time. The data processing module 5 and the communication module 6 are installed in a cold-resistant and waterproof equipment box, and a power supply module 7 is installed in the equipment box to power the data processing module 5 and the communication module 6. The temperature sensor 2 and the angle sensor 9 can be powered by the external power supply module 7, or by the power supply module installed in the pipe 1.

[0043] In specific implementation, the data processing module 5 includes a microcontroller system module, which includes, but is not limited to, a 51 series, ATmega series, or higher-performance programmable microcontroller processor and peripheral circuits; the communication module 6 is a SIM module, WIFI module, 433M module, or satellite module; the remote receiving device includes, but is not limited to, mobile phones, computers, tablets, and other network-connected electronic devices. The power module 7 includes a voltage regulator circuit and a rechargeable battery connected in sequence, and the solar photovoltaic panel 8 is connected to the voltage regulator circuit.

[0044] In specific implementation, the rechargeable batteries 2-5 include, but are not limited to, lead-acid batteries, gel batteries, lithium batteries, and nickel-metal hydride batteries.

[0045] This invention uses a temperature probe 1 and a data processing module 5 to detect the ice layer thickness, and then transmits the data in real time to a remote receiving device via a communication module 6. This invention offers the advantages of low cost, high precision, and real-time monitoring.

[0046] For example, in a test area with a water depth of 2 meters and an estimated maximum ice thickness of approximately 100 cm, pipe 1 is selected to be 3 meters long. Two 1.5-meter-long pipes 1 are connected by threads to reach a total length of 3 meters. Approximately 60 temperature sensors 2 are installed. Before or after the water surface freezes, pipe 1 is vertically positioned in the water using methods such as floats, drilling, or piling, with 2 meters of pipe 1 below the water surface and 1 meter above the water surface.

[0047] The specific data processing module 5's method for calculating the ice layer thickness based on the temperature data collected by the temperature probe 1 is not covered by this utility model and will not be described further here.

[0048] Because temperature sensors 2 are located inside the ice layer and are not easily replaced, in order to improve measurement accuracy and prevent mutual interference between temperature sensors 2 and data distortion caused by damage to individual temperature sensors 2 interfering with the data bus or affecting the power supply, the 60 temperature sensors 2 in this example are divided into 3 groups, with 20 sensors in each group using separate power supplies and data buses. If the temperature sensors 2 in 2 of the 3 groups are damaged and affect the data bus, preventing the correct transmission of data, the remaining group can still work independently, ensuring the stability and reliability of the measurement.

[0049] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
