Description

Technical Field

[0001] The present invention relates to the technical field of ice thickness measuring equipment, and in particular to a device capable of automatically and accurately measuring ice thickness through long-distance remote control. Background Art

[0002] As a carrier of clean hydropower energy, pumped-storage power stations have become increasingly important in the construction of new energy systems, and are regarded as an important direction for the development of new energy technologies worldwide. However, in cold regions, the upper reservoirs of pumped-storage power stations are prone to freezing in winter. The ice cover formed not only hinders the pumping and releasing process, but may also pose a threat to the safety of the power station in severe cases. Therefore, solving the freezing problem of pumped-storage power stations in cold regions and ensuring the stable operation of the power stations have become technical difficulties that need to be overcome urgently. As one of the important influencing factors in the research process, the thickness of the ice layer is still mainly measured by manual drilling. This method is not only labor-intensive and inefficient, but also requires surveyors to work for a long time in a low-temperature environment. Especially when the ice layer is thin, there is a risk of surveyors falling from the ice surface. Therefore, the present invention designs a device that can be remotely controlled from a distance to automatically and accurately measure the thickness of the ice surface. Summary of the Invention

[0024] In this embodiment, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, the ice thickness measurement system includes a displacement data acquisition device 15, a lifting control device 5, a pull-wire displacement sensor 1 and a pressure sensor 19.

[0025] The use method and advantages of the present invention: The device that can automatically and accurately measure the thickness of the ice surface by remote control works as follows:

[0026] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, a signal is transmitted to the motion control device 13, which drives the motion motor 14 to move the ice thickness measurement device to a designated position, thereby controlling the ice thickness measurement system to perform ice thickness measurements. Alternatively, the motion control device 13 can be driven by a GPS remote control device 2, which automatically navigates and records the movement trajectory and rest position by setting the operation route and parameters in the control system. After the device reaches the designated position, the GPS remote control device 2 transmits a signal to the ice thickness measurement system's lift control device 5, causing the screw lift 6 to control the hollow screw 3 to drive the melt drill bit 21 downward to melt the ice. When the melt drill bit 21 contacts the ice surface, the melt drill bit 21, the lower shell 18, and the upper shell 17 remain stationary on the ice surface. The hollow screw 3 drives the pressure head 16 to penetrate the upper shell 17. After descending a certain height, the pressure head 16 contacts the pressure sensor 19, providing downward pressure for the melt drill bit 21. After the melt drill bit 21 penetrates the ice, its own gravity causes it to fall from the lower shell 18 and upper shell 17, causing the pressure head 16 to separate from the pressure sensor 19. At this point, the pressure sensor 19 transmits a signal to the displacement data acquisition device 15, which records the displacement data at that moment and obtains ice thickness data. This data is then transmitted to the lift control device 5, causing the melt drill bit 21 to stop its downward movement and retract. Once the melt drill bit 21 is fully retracted, the motion control device 13 continues to control the device to move to the next point for measurement.
