Embodiment Construction

[0008] Such as figure 1 , figure 2 As shown: there is a hollow cylinder 1 made of 316 stainless steel, polyethylene and other materials, which can be cylindrical or square, etc. The lower end of the hollow cylinder 1 is connected with the wave-absorbing water inlet device 2, and the wave-absorbing water inlet Device 2 is a device with a filter hole on it, and its structure is the same as that of the wave-absorbing water inlet device used in the existing normative tide well, and the aperture of the filter hole should meet the requirements of wave-elimination and tidal followability. A laser reflective float 3 is built in the hollow cylinder 1, and the laser reflective float 3 is made of a material with excellent corrosion resistance and lubricating properties and capable of reflecting laser light, such as polytetrafluoroethylene. The upper end of the hollow cylinder 1 is provided with a laser ranging module 4, the laser ranging module 4 adopts the SKD-30 of Sanke Optoelectron...

Description

technical field [0001] The invention relates to an ocean tide level observation device, in particular to a laser automatic tide gauge with simple structure, low cost, firmness and durability, easy installation and operation, high degree of automation and high observation accuracy. Background technique [0002] Tide gauge is the observation of tidal fluctuation at a certain time interval at a fixed point, and it is an important part of marine engineering survey, channel survey, marine survey, seaport wharf monitoring and other work. At present, the known tide gauges mainly include tide gauges, float type tide gauges, acoustic tide gauges, pressure type tide gauges and the like. The tide gauge is an open geometric mechanical tide gauge. It is set up on the wharf wall or shore during measurement, and the surveyors directly observe the readings manually. The advantages are simple structure, low cost, light and flexible; the disadvantages are low degree of automation, Poor filte...
