Abstract
The utility model discloses a level gauge for oil tank bottom detection. The level gauge comprises a laser range finder, an adjustable chassis and a tripod, wherein the laser range finder is arranged at the upper end of the adjustable chassis, and the lower end of the adjustable chassis is connected with the tripod; the adjustable chassis comprises a laser range finder fixing disc and a tripod fixing disc which are vertically arranged; the laser range finder is arranged on the laser range finder fixing disc; the tripod is arranged on the tripod fixing disc; the laser range finder fixing disc and the tripod fixing disc are connected and supported through three height adjustable rods; screws for adjusting are arranged on the height adjustable rods; and a spring type range finder fixing clip for clamping the laser range finder is arranged on the laser range finder fixing disc. According to the level gauge, the problems such as large error, high labor intensity and the like during current tank bottom elevation measurement are solved.
Description
Technical field
The utility model relates to level pick-up unit at the bottom of oil tank, specifically a kind of spirit-leveling instrument for detecting at the bottom of oil tank.
Background technology
Large oil tank is the main metering and storing apparatus tool of large energy trading clearing between country or enterprise, belongs to compulsory verification metering outfit.At present, the construction that design volume is no less than 100,000 sides' super-huge oil tank is risen gradually, is generally large petrochemical plant and stores crude oil and use.Because design volume is large, less error will cause larger volume to come in and go out.How to utilize advanced metering method, accurately measure its volume is the core of super-huge tank operation always, is also industry a great problem simultaneously.Wherein, oil tank bottom measurement amount existing problems are more serious, and measuring accuracy is difficult to improve.With flowmeter contrast test in, error through being everlasting ± (10%-20%), far beyond national regulation.For example, 100,000 m
3the end amount of oil tank is conventionally at 2000m
3left and right, ± error (10%-20%) is equivalent to ± (100-200) ton crude oil is very surprising.
The key that measures accuracy of measurement at the bottom of at the bottom of raising tank is accurately to measure the absolute altitude of calibrating point.100000 m
3in above super-huge oil tank, environment is more complicated: in tank, light is very faint, uneven at the bottom of tank, and annex is not only much but also more complicated.These have all had a strong impact on the precision of measuring absolute altitude, have caused larger measuring error.
At present, at the bottom of tank, level measurement has general absolute altitude method and two kinds of methods of digital level.These two kinds of methods are basic identical, and difference is digital level automatic reading.These two kinds of methods are all to adopt spirit-leveling instrument, elevation ruler and electric torch to measure, and in the region of 40 meters of unglazed and radiuses, by spirit-leveling instrument, look for the bright spot of electric torch very difficult, and elevation ruler can not vertically place conventionally, and error in dipping is larger.Conventionally, detect 100,000 m
3tank at the bottom of need about 3 hours consuming time, testing staff's labour intensity is very high.
Summary of the invention
The purpose of this utility model is to provide a kind of spirit-leveling instrument for detecting at the bottom of oil tank, solves the problems such as the error that level measurement exists at the bottom of current tank is large, labour intensity is high.
In order to reach above-mentioned purpose, the utility model has adopted following technical scheme, and a kind of spirit-leveling instrument for detecting at the bottom of oil tank, comprises laser range finder, adjustable chassis, tripod, laser range finder is installed in described adjustable chassis upper end, and lower end connects tripod.
Described adjustable chassis comprises laser range finder shaft collar, the tripod shaft collar arranging one on the other, and described laser range finder is arranged on laser range finder shaft collar, and described tripod is arranged on tripod shaft collar.
Between described laser range finder shaft collar, tripod shaft collar, by three height regulating rods, connect and support, on height regulating rod, be provided with the screw that regulates use.
On described laser range finder shaft collar, be provided with for blocking the spring stadimeter geometrical clamp of laser range finder.
Described tripod shaft collar center is offered for the tripod fixing hole of tripod is installed.
Compared to prior art, the utlity model has following beneficial effect:
At the bottom of this tank, detect spirit-leveling instrument, be mainly used in Petroleum & Petrochemical Enterprises and local storage tank volume calibration bodies and agencies at different levels, be also applicable to relate to the poor level measurement operation of light condition.At the bottom of the tank of light dark, can help testing staff to carry out quickly and accurately level measurement, not only obviously reduced labour intensity, also greatly improved calibration accuracy; Compare with ordinary level, simple in structure, cost is lower, easy to maintenance, and laser range finder can also be done separately other and measure use, and integration of instruments rate is higher.
