Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0033] Tide gauges are generally installed in tide wells for online real-time monitoring of the tide level, and generally have a 24-hour uninterrupted long-term work requirement. How to provide a method and device capable of performing on-line calibration of the tide gauge on site is what needs to be described in detail in this embodiment.

[0034] see Figure 1-Figure 12 , a float-type tide gauge laser ranging on-site comparison device, including a transparent plate 3, a strip-shaped through-slot 301 is opened on the transparent plate 3; The mounting hole of the laser bracket 5; the laser bracket 5 is L-shaped, one end is fixed on the transparent plate 3, and the other end is used to lean against the laser 4; the emission direction of the laser 4 is downward, and passes through the strip-shaped channel Groove 301; one side of the transparent...

Abstract

The invention relates to a float-type tide gauge laser ranging in situ comparison device, comprising a transparent board, wherein a strip-shaped through groove is formed in the transparent board; a plurality of mounting holes used for mounting a laser support are formed along the strip-shaped through groove; the laser support is L-shaped, one end of the laser support is fixed on the transparent board, and the other end of the laser support is used for abutting a laser; a transmitting direction of the laser is vertically downward and passes through the strip-shaped through groove; one side of the transparent board is rotatably connected with a pair of supporting bars, a plurality of upright post mounting holes are formed in each supporting bar, each upright post mounting hole is used for being fixedly connected with one upright post, another group of upright post mounting holes are formed in the other side of the transparent board, and each upright post mounting hole in the group is also used for being fixedly connected with one upright post; each upright post stands at the edgewise part of the mouth of a tide gauge well, and three-point support is formed; a laser bounce float is arranged in the tide gauge well in a floating manner, the laser bounce float longitudinally corresponds to the laser, and in situ calibration is performed by virtue of data read through laser ranging ofthe laser and data read by a tide gauge.

Description

technical field [0001] The invention relates to a device for calibrating the accuracy of a tide gauge, specifically, an on-site comparison device for laser distance measurement of a float type tide gauge. Background technique [0002] Tide level observation is one of the most important items in marine hydrological observation. Tidal level changes are directly related to the entry and exit of ships, marine and coastal engineering design, naval mine deployment depth, storm surge forecast, tidal reclamation, tidal power generation, etc. Tide level data are required for determining mean sea level and depth datum, making tide tables, forecasting storm surges, commanding maritime operations, laying submarine cables, and forecasting earthquakes. Therefore, obtaining accurate tide level data is of great significance for mastering local tide types, changing laws, disaster prevention and mitigation, marine engineering construction, and military affairs. [0003] Tide gauge, an instr...
