Abstract
An auto water level recording device using in a shore tide observation well is characterized in that a band pulley and a change gear box which are connected with a float and a weight are capable of transforming the vertical movement of the float which floats on the surface into change of rotating angle, the vertical movement of the float reflects change of water level, and then change of rotating angle is transferred into electric signals which is processed by a microprocessor to obtain water level data. The float water level meter has the advantages of accurate record, excellent stability, and being capable of being used to renew water level viewing devices of sea monitoring station home and aboard.
Description
Technical field
The utility model is to measure the apparatus that sea level fluctuations changes, and specifically is meant a kind of instrument that utilizes the lifting of water surface float to measure SEA LEVEL VARIATION.
Background technology
Forecast and control that ocean water level is observed oceanic tide forecast and research of tidal fluctuations rule and disastrous weather provide important marine hydrology environmental data.
At present, the float type level meter that is arranged in the tide gauge well of seashore limit is the key instrument equipment of beach water-level observation.This apparatus structure is simple, and is easy for installation, but what adopt is the core of mechanical clock as timing and drive system, uses hard-tipped pen and the special-purpose paper media as record, needs every day during the school and change recording chart, and personnel labor intensity is very big.In addition, all there are some problems, influence its long-term use in water-level observation at aspects such as accurate timing, accurate recording, data processing, plant maintenances.
Summary of the invention
The utility model adopts through transmission shaft and the displacement coder that the rope sheave that twines the float wire rope is communicated with, the SEA LEVEL VARIATION that the vertical movement of water surface float reflects is noted, accurately to note down sea level fluctuations variation in the tide gauge well automatically.
Float type level meter described in the utility model is made up of float, weight, rope sheave, displacement coder, signal processing circuit, record display device etc.
Rope sheave is that the different wheel of two diameters that is fixed together constitutes, and is used to connect float and weight.
Float is the Plastic Welding body of inner packing material, keeps afloat, and is fixedly connected on the rope sheave by wire rope is single-ended, and the wire rope of its connection is wrapped on the bull wheel of rope sheave.Weight is fixedly connected on the rope sheave by wire rope is single-ended, and the wire rope of its connection is wrapped on the steamboat of rope sheave.The wire rope that connects weight is opposite with the winding direction of the wire rope that is connected float on rope sheave, with the attitude that reaches displacer weight, keeps float to keep afloat.
The transmission shaft of rope sheave is connected with displacement coder by change speed gear box, displacement coder is connected with signal processing circuit board, signal processing circuit board is connected with the record display device by output cable, and can be by multiple communication mode and the outside exchanges data that realizes.
When float type level meter is used, be installed on the horizontal table of tide gauge well, float floats on the water surface in the tide gauge well by wire rope.During SEA LEVEL VARIATION, float is with water surface fluctuation, under the equilibrium activity of weight, the wire rope that connects float on the rope sheave is wound or discharges, rope sheave rotates thereupon, the SEA LEVEL VARIATION that the rope sheave that rotates reflects the float lifting by rope sheave transmission shaft and change speed gear box changes output with angle and is sent to displacement coder, displacement coder becomes electric signal with this angle change transitions, and be sent on the signal processing circuit board with digital signaling, signal processing circuit board carries out processing data information by microprocessor and arithmetical unit, obtain the SEA LEVEL VARIATION data, and show and record.
Float type level meter data recording described in the utility model is accurate, good stability, will be used to upgrade the instrument of gauge observation at domestic existing marine monitoring station.
