Abstract
An inclined-tube type water level measuring device comprises a gauging pipe and a laser range finder and the gauging pipe can be laid with being inclined according to the slop of a dam. The lower end of the gauging pipe is arranged at the upper part of a measured water body and the upper end of the gauging pipe is arranged at the top of the dam or bank slop. The utility model structurally further comprises a water level calculation converter and a monitoring data communicator, and the laser range finder is arranged at the upper end of the gauging pipe. A laser reflection float which can float on the water surface is further arranged in the gauging pipe. The utility model is realized and the prior laser distance measuring technology is applied, so the utility model has the advantages of high measurement reliability and small error. Because the data that the laser range finder measures can be operated through the water level calculation converter and sent through the monitoring data communicator, the prior national three-proof information network can be directly accessed, thereby realizing that the monitoring center applies the real-time 24-hour monitoring and analysis to the water body basin. The utility model has simple structure, can be easily arranged, has low building cost, can be used as the permanent device and also can be used as the temporary installation.
Description
Technical field
The utility model relates to a kind of level measurement device, relates in particular to a kind of inclined tube-type level measurement device.
Background technology
Water level monitoring to great water body basins such as rivers and lakes, reservoirs is to be related to the important engineering that the mankind prevent and reduce natural disasters, traditional vertical shaft type water level measurement method is to set up monitoring tower on the tested water body base, the height of its monitoring tower is decided according to the elevation of tested water body, generally need reach 20～30 meters high, must on the water body base, set up sufficiently solid column foot for this reason, and need on the dykes and dams top, to build one towards the access bridge of surveying tower, and generally need to select just can build construction low water season, its construction condition harshness, cost is higher.People have begun to attempt building inclined shaft (pipe) formula measurement mechanism now, but because of level sensor adopts traditional Mechanical Contact formula measuring method, need to use float and hammer interlock to cooperate, generally need be arranged to the diclinic tubular type, this measurement mechanism increases along with the length of inclined tube or the pitch angle reduces and make the accuracy and the reliability variation of measurement, even it is ineffective, so desirable not enough in practical application.
Summary of the invention
For overcoming the defective of existing level measurement device, it is a kind of simple in structure that the utility model provides, and can adapt to multiple matrix condition, the inclined tube-type level measurement device that construction cost is lower.
The utility model is to realize like this; A kind of inclined tube-type level measurement device comprises and surveys pipe, laser range finder; Described survey pipe can tilt to lay with the gradient of dykes and dams, and the lower end is arranged on the bottom of tested water body, and the upper end is arranged on dykes and dams or bank slope top, comprises also that structurally water level calculates converter; Described laser range finder is installed in surveys the pipe upper end, and the detecting light beam of laser range finder and the center axially parallel of surveying pipe also are provided with one and can be suspended on the water surface and can be with the lifting of water level along surveying the laser-bounce float that tubular axis moves up and down in surveying pipe; Be connected with data and control signal transmission line between described laser range finder and the converter.
As further improvement of the utility model, described inclined tube-type level measurement device structurally also is provided with the Monitoring Data sender, is connected with data and control signal transmission line between sender and the converter.
Further improve as of the present utility model, described survey pipe is the steel pipe of 100～500mm or the straight tube that plastic tube is made by diameter.Described survey pipe lower end is provided with filtering screen.Surveying the fixedly anchor block of managing along the line and being provided with between the dykes and dams slope more than 2 or 2, the centre also can be provided with buttress.
Also can be provided with the formula of flooding of holding survey pipe lower end according to circumstances in the bottom of tested water body and log well, described well logging is provided with siphunculus or the through hole that communicates with tested water body.Be provided with the workplace of holding laser range finder, converter and sender at dykes and dams or bank base top.
Realize the utility model, owing to used existing laser ranging technique, and be provided with can following water-level lifting slides in surveying pipe the laser-bounce float, can be reliably the laser beam of reflector laser stadimeter exactly, thereby have and measure reliability height, the advantage that error is little.Because the measured data of stadimeter can be calculated converter by water level and carry out computing and by the transmission of Monitoring Data sender, make remote monitoring terminal can obtain the data of measurement point in real time.The utility model can be removed artificial point from and sends out, and realizes the unmanned automatic continuous monitoring, can directly insert country's existing three anti-information networks, thereby realize that monitoring center carries out real-time omnibearing monitoring analysis to the water body basin of multiple spot face.
Of the present utility model simple in structure, install easily, can adapt under the environmental baseline of multiple matrix and install and use, its cost is not enough builds 1/10th of vertical shaft type monitoring tower, and can be used as permanent use, also can be used as provisional installing and using.
