Description

Technical Field

[0001] The present invention relates to the technical field of glacier sliding rate measurement, and in particular to a device for measuring the local sliding rate of a glacier. Background Art

[0002] Measuring the local sliding rate of glaciers usually involves monitoring the displacement changes on the surface or inside of the glacier through high-precision instruments to assess the movement of the glacier in a specific area. Common methods include installing GPS measuring devices to track changes in the position of glacier surface points, using ground-based radar interferometers (GB-InSAR) to monitor large-scale sliding conditions, or accurately recording local sliding rates through displacement sensors. In addition, combined with mechanical auxiliary equipment such as hammer devices, measuring points can be applied on the surface or inside of the glacier, and hydraulic devices and positioning systems can be used to ensure that the measurement data is stable and reliable. These methods are crucial to studying glacier dynamics and the impact of climate change.

[0003] In the actual implementation process, when fixing the monitoring equipment on the surface of the glacier, it usually requires the cooperation of multiple staff members to firmly insert the fixing base into the glacier by repeated hammering to ensure the stability of the equipment. However, due to the complex surface characteristics of the glacier, the fixing process may be disturbed by external forces. Especially after the fixing is completed, if there is strong wind or external impact, the fixing device may become loose or fall over, which will not only cause displacement of the monitoring equipment or data collection errors, but may also cause damage to the equipment itself, seriously affecting the continuity of the monitoring work and the reliability of the data.

[0004] Therefore, we made improvements to this and proposed a device to measure the local sliding rate of glaciers. Summary of the invention

[0005] The purpose of the present invention is to provide a device for measuring the local sliding rate of a glacier, which solves the problem that when fixing the monitoring equipment on the surface of the glacier, it usually requires the cooperation of multiple staff members to firmly insert the fixing base into the interior of the glacier by repeated hammering to ensure the stability of the equipment. However, due to the complex surface characteristics of the glacier, the fixing process may be disturbed by external forces. In particular, after the fixing is completed, if there is strong wind or external impact, the fixing device may become loose or fall over, which will not only cause displacement of the monitoring equipment or data collection errors, but may also cause damage to the equipment body, seriously affecting the continuity of the monitoring work and the reliability of the data.

[0008] As a preferred technical solution of the present application, a triangular groove is provided on the lower surface of the long plate, and corresponds to the position of the two rotating plates.

[0009] As a preferred technical solution of the present application, the opposing surfaces of the two rotating plates are both configured to be arc-shaped for easy extrusion.

[0010] As a preferred technical solution of the present application, the fixing device includes four shells, positioning piles are fixedly connected under the shells, pin connectors are fixedly connected on the shells, and the pin connectors are fixedly connected under the supporting legs.

[0011] As a preferred technical solution of the present application, the reinforcement device includes four circular plates, which are rotatably connected in the shell, and two arc grooves are symmetrically opened in the circular plates. Sliding columns are slidably connected in the arc grooves, and a reinforcement plate is fixedly connected under the sliding column, and the reinforcement plate is slidably connected in the shell.

[0012] As a preferred technical solution of the present application, a pressure plate is fixedly connected to the circular plate, and the pressure plate and the circular plate are welded into an integrated structure.

[0013] As a preferred technical solution of the present application, the limiting device includes a limiting shell, a rectangular groove is opened in the limiting shell, a rectangular block is slidably connected in the rectangular groove, a handle is fixedly connected to the outside of the rectangular block, an extrusion block is fixedly connected to the rectangular block, the extrusion block is slidably connected in the limiting shell, a reset spring is fixedly connected under the rectangular block, and the reset spring is fixedly connected in the limiting shell.

[0014] Compared with the prior art, the present invention has the following beneficial effects: In the scheme of this application: 1. Through the setting of hydraulic cylinder, traction block and counterweight block, when the equipment needs to be fixed on the ice surface, the frame is first slid into the slide groove through the slider, and the frame is firmly connected to the glacier sliding rate measuring instrument body with the bolts on the long plate. Then, the hydraulic cylinder is started, and the hydraulic cylinder drives the traction block to move and simultaneously drives the two rotating plates to move. When the rotating plate moves to the pull rod position, the pull rod applies an extrusion force to the rotating plate to make it rotate around the rotating axis. At this time, the pull rod is clamped between the two rotating plates, and the pull spring applies elastic force to the connecting rod to reset the rotating plate and firmly clamp the pull rod. The hydraulic cylinder further drives the traction block to move upward, and at the same time drives the pull rod through the rotating plate Movement, the pull rod drives the counterweight to slide in the frame during the movement and applies pressure to the frame. When the rotating plate moves to the triangular groove position in the long plate, the triangular groove applies additional squeezing force to the rotating plate, causing the rotating plate to expand relatively. At this time, the pull rod applies pulling force, and the counterweight continues to slide under the action of gravity, forming effective downward pressure on the frame. The four supporting legs then expand downward, and at the same time, the positioning piles are firmly stuck in the ice surface to achieve stable fixation of the equipment. This solves the problem in the prior art that when fixing the glacier sliding rate measuring instrument body on the glacier surface, it usually requires the cooperation of multiple staff members to insert the fixing seat firmly into the glacier by repeated hammering, which is a more troublesome problem. 2. Through the arrangement of the circular plate, arc groove, reinforcement plate and pressure plate, when the shell is inserted into the ice surface, the pressure plate is struck by external force to drive the circular plate to rotate in the shell. The rotation of the circular plate drives the sliding column in the arc groove to slide along the specified track. At the same time, the sliding column pushes the reinforcement plate to slide inside the shell and gradually extends in the lateral direction of the ice surface. In this process, the precise displacement of the reinforcement plate is achieved through the linkage of the arc groove and the sliding column, thereby enhancing the lateral fixing effect of the shell in the ice surface, ensuring the stability and external force resistance of the device, and solving the problem in the prior art that the fixing device may become loose or tip over when encountering strong wind or external impact, which will not only cause the displacement of the monitoring equipment or the data collection error; 3. Through the arrangement of the limiting shell, the rectangular block, the extrusion block and the locking rod, when the supporting leg needs to be transferred and stored, the supporting leg can be directly pressed, and the supporting leg drives the locking rod to apply thrust to the extrusion block. After the extrusion block is subjected to the extrusion force, it slides in the limiting shell. When the locking rod passes the extrusion block, the reset spring applies elastic force to the rectangular block and drives the extrusion block to reset, which solves the problem in the prior art that the supporting leg may be scattered and damaged when being transferred and stored; BRIEF DESCRIPTION OF THE DRAWINGS
