Embodiment Construction

[0028] The present invention will be further described below through specific embodiments.

[0029] refer to figure 1 , a real-time measurement device for sea cliff erosion data, including a support plate 1, a pull cord 2, an elastic member, a support pile 7, a pulley 3, an angle machine 4, a data processing device and a power supply 10. The support plate 1 is vertically fixed on the sea cliff face, and it is a circular or square steel plate with a certain rigidity, with a diameter or side length between 20cm and 30cm, and a thickness between 2mm and 3mm. A reinforcement pull ring is welded in the middle of one side of the support plate 1 . The stay rope 2 is a steel strand, one end of which is fixed on the pull ring of the support plate 1, and the other end goes around the pulley 3 and connects one end of the elastic member. The elastic member is a spring 6 and is in a stretched state. Quantitative. The sea cliff face and the top of the sea cliff are provided with a throug...

Abstract

A sea cliff erosion data real time measurement device and method are disclosed. The sea cliff erosion data real time measurement device comprises a pull rope, an elastic member, a support pile, an angle machine and a data processing device, wherein one end of the pull rope is fixed on a surface of a sea cliff while the other end is connected with one end of the elastic member, the other end of the elastic member is fixedly connected with the support pile and is in a tensional state, the support pile is fixed on a top surface of the sea cliff, the angle machine is arranged on the top surface of the sea cliff, the pull rope is clamped on a top part of the angle machine so as to drive the angle machine to rotate, the pull rope is arranged in such a way that one voltage signal is triggered upon one revolution of the angle machine, and the data processing device is connected with a signal output end of the angle machine so as to collect and record the voltage signal and corresponding time. The sea cliff erosion data real time measurement device and method are advantaged by reliable measurement results and high labor saving and time saving performance.

Description

technical field [0001] The invention relates to the field of coastal erosion protection, in particular to a device and method for real-time measurement of sea cliff erosion data. Background technique [0002] The erosion of soft sea cliffs is a global problem. There are various types of eroded coasts in the world, among which soft coasts have become an important type of eroded coasts because of their fast erosion rate and large scale. Soft coasts are generally composed of soft or loose strata such as Quaternary sedimentary layers, bedrock weathered layers, residual slope deposits, or eolian sands. Compared with rocky coasts, soft coasts have lower strength. Erosion is prone to occur under the environment, and the erosion rate is relatively high. The erosion of soft sea cliffs causes the land area to gradually decrease, and the buildings and facilities above the sea cliffs are vulnerable to damage. At present, the erosion distance of soft sea cliffs is generally obtained ba...
