Abstract
Description
Предлагаемое изобретение относится к измерительной технике в области диагностики цилиндрических и сферических резервуаров и может быть использовано для оценки остаточного ресурса стенки резервуара по малоцикловой усталости.The present invention relates to measuring technique in the field of diagnostics of cylindrical and spherical tanks and can be used to assess the residual life of the tank wall by low-cycle fatigue.
Наиболее близким к предлагаемому изобретению является устройство для измерения геометрической деформации стенки вертикальных резервуаров [Патент RU №74706, G01B 5/20, 2006], содержащее лазерный теодолит, сопряженный с блоком на базе цифровой видеокамеры для снятия оптической информации с теодолита и передачи ее в вычислительный комплекс на базе ЭВМ для обработки.Closest to the proposed invention is a device for measuring the geometric deformation of the wall of vertical tanks [Patent RU No. 74706, G01B 5/20, 2006], containing a laser theodolite paired with a unit based on a digital video camera for removing optical information from the theodolite and transmitting it to the computing computer-based complex for processing.
Недостатками данной установки является то, что устройство устанавливается перед резервуаром и измеряет геометрию поверхности стенки, что затрудняет его использование, так как оборудование занимает определенное технологическое пространство (площадку перед резервуаром); не учитывается влияние внешней среды (туман, осадки), что создает погрешность при снятии визуальной информации; не учитывает изменение размеров стенки вследствие перепадов температуры.The disadvantages of this installation is that the device is installed in front of the tank and measures the geometry of the wall surface, which makes it difficult to use, since the equipment occupies a certain technological space (platform in front of the tank); the influence of the external environment (fog, precipitation) is not taken into account, which creates an error when removing visual information; does not take into account the change in wall size due to temperature changes.
Предлагаемое изобретение решает задачу бесконтактного измерения геометрической деформации стенок вертикальных и сферических резервуаров в процессе эксплуатации, уменьшения технологического пространства и повышения точности измерения за счет устранения зависимости от погодных условий и прочих внешних воздействий (температурного расширения).The present invention solves the problem of non-contact measurement of the geometric deformation of the walls of vertical and spherical tanks during operation, reducing the technological space and improving the accuracy of measurements by eliminating the dependence on weather conditions and other external influences (thermal expansion).
Эта задача решается устройством, содержащим лазерный дальномер с датчиком температуры, закрепленный на внутренней стенке резервуара, сопряженный с вычислительным комплексом на базе ЭВМ для обработки информации и выдачи результатов.This problem is solved by a device containing a laser rangefinder with a temperature sensor, mounted on the inner wall of the tank, coupled to a computer-based computer system for processing information and outputting results.
Указанные признаки являются существенными для решения задачи предлагаемого изобретения:These signs are essential for solving the problem of the invention:
1. Лазерный дальномер с датчиком температуры закрепляются на внутренней поверхности стенки резервуара, благодаря этому признаку устройство занимает минимальное технологическое пространство (нет необходимости подготавливать площадку перед резервуаром, устройство не создает помех обслуживающему персоналу), устраняется влияние внешней среды (туман, осадки).1. A laser range finder with a temperature sensor is fixed on the inner surface of the tank wall, due to this feature the device occupies minimal technological space (there is no need to prepare the site in front of the tank, the device does not interfere with maintenance personnel), the influence of the external environment (fog, precipitation) is eliminated.
2. Данные, получаемые от датчика температуры, позволяют скорректировать точность измерения деформации стенок резервуара за счет учета перепадов температуры.2. The data received from the temperature sensor allows you to adjust the accuracy of measuring the deformation of the walls of the tank by taking into account temperature differences.
Сущность предлагаемого изобретения поясняется принципиальной схемой, где на фиг. 1 представлена конструкция и изменяемые параметры резервуара (вид сбоку). Лазерный дальномер с датчиком температуры (1) закрепляется на внутренней поверхности стенки резервуара (2), им замеряется расстояние до противоположной образующей стенки резервуара и температура металла стенки, полученная информация передается в вычислительный комплекс на базе ЭВМ (3), который обрабатывает данные и вычисляет расстояние между стенками резервуара с учетом поправок на температуру, в процессе заполнения резервуара светлыми нефтепродуктами (газами), стенки нагружаются и изменяют свою геометрию, измерение расстояния между стенками и температуры проводится постоянно по мере заполнения, а вычислительный комплекс рассчитывает величину геометрической деформации стенки резервуара с учетом температурных поправок.The essence of the invention is illustrated by the circuit diagram, where in FIG. 1 shows the design and variable parameters of the tank (side view). A laser range finder with a temperature sensor (1) is mounted on the inner surface of the tank wall (2), it measures the distance to the opposite generatrix of the tank wall and the wall metal temperature, the received information is transmitted to a computer-based computer complex (3), which processes the data and calculates the distance between the walls of the tank, taking into account temperature adjustments, in the process of filling the tank with light oil products (gases), the walls are loaded and change their geometry, measuring the distance between At the same time, temperature and temperature are carried out continuously as they are filled, and the computer complex calculates the value of the geometric deformation of the tank wall taking into account temperature corrections.
