Problems solved by technology

[0006] At present, traditional surveying instruments, such as levels, theodolites and total stations, cannot set up benchmarks in the cave, and the light in the cave is poor, so they cannot measure the depth of the cave.

Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0030] In order to solve the problem of being unable to measure the depth of sea caves in the prior art, the present invention provides a measuring device for measuring the depth of sea caves and a method for measuring the depth of sea caves. Through the cooperation of guide rails and vertical rods, two-dimensional The mobile platform can adjust the position of the laser rangefinder through the two-dimensional mobile platform, and can measure the depth of each measurement point of the entire sea cave with full coverage. Moreover, the measuring device can be fixed on the sea cliff surface outside the sea cave through fixed piles, and it does not need to go to the sea cave for operation, and it can find a position that is easy to fix and set to a level as much as possible. The operation is convenient and safe, and the measurement data Comprehens...

Abstract

The present invention relates to a measurement device for measurement of a marine cave depth and a method for measurement of a marine cave depth. Through cooperation of a guide rail and a vertical rod, a two-dimensional mobile platform is obtained, and the two-dimensional mobile platform is configured to regulate the position of a laser distance measurer to measure the cave depth of each measurement point of the whole marine cave in a full-covering mode. The method for measurement of the marine cave depth is based on the measurement device, the measurement device can be fixed on a sea cliff surface except the marine cave through fixed pillars, positions with easy fixing and horizontal arrangement can be found as far as possible with no need for operation at the marine cave, and therefore,the operation is convenient and safe, and the measurement data is comprehensive and accurate.

Description

technical field [0001] The invention relates to the field of geological hazards in coastal zones, more specifically, to a measuring device for measuring the depth of sea caves and a method for measuring the depth of sea caves. Background technique [0002] Sea caves are a kind of sea erosion landform developed on rocky sea cliffs. They are caves formed after long-term wave action on the weak parts of sea cliffs. Different from the formation mechanism of land caves, sea caves are caused by mechanical erosion of waves. The joints, fissures, weak interlayers and weak dikes of rocky sea cliffs are easily eroded by waves, and then collapse and break, gradually forming sea caves. Sea caves range in depth from tens of centimeters to tens of meters. Some sea caves are only one meter high and tens of meters deep. Seen from the outside, the inside of the cave is pitch black. [0003] Measuring the maximum depth of sea caves is of great significance, specifically reflected in: [000...
