Abstract
The utility model relates to a fully automatic well pumping unit photoelectric detecting device, which comprises a photoelectric unit and an illuminating unit or reflection unit. The photoelectric unit and the light source or reflection unit are disposed on an optical path of the photoelectric unit. The photoelectric detecting device is low in operating environment requirement, the photoelectric unit of the photoelectric detecting device does not contact with crude oil when in operation and is unrelated to other detected indexes of the crude oil, such as temperature, pressure, flow speed, flow volume and the like, and thereby photoelectric detecting device is low in requirements on operating environment and operating condition, and is high in sensibility and high in acquisition accuracy.
Description
Technical field
Whether fuel-displaced the utility model relate to a kind of pumping unit of well photoelectric detection system of surveying.
Background technology
At present in the oil pumping process of stripper and intermittent oil well, no matter whether oil well is fuel-displaced, pumping unit of well is all carrying out oil pumping work always, so very power consumption, and the application life that can reduce pumping unit of well, therefore, in order to reach purpose of power saving, just wish that at oil well the running of pumping unit of well drive motors guarantees fuel-displaced when fuel-displaced; Do not go out oil condition at oil well, pumping unit of well is out of service, in idle running.
For reaching this purpose, dual mode is arranged at present, a kind of is the outlet pressure detection method, another kind is the motor load detection method, the outlet pressure detection method is at oil well exit setting pressure sensor, and when pressure sensor was experienced pressure signal, thinking had oil condition.The method has two shortcomings:
1, less in the oil well pressure outlet, when presenting the smooth flow state, this moment, pressure sensor did not have pressure signal output, caused the single unit system attonity;
2, the crude oil dielectric viscosity is bigger, presents semi-fluid condition, pressure sensor is sticked to make it lose detectability easily, or along with long-play, senser element is constituted infringement.
Motor load detection method: according to oil condition being arranged, the principle that the motor rotation electric current is bigger.This principle adaptive surface is narrow, is easy to generate misoperation in different operating modes.
Therefore how to provide a kind of environment, little, the highly sensitive fuel-displaced detecting devices of operation condition requirement to become a urgent problem.
The utility model content
The above-mentioned technical problem of the utility model for existing in the solution background technology, and the pumping unit of well that a kind of cost is low, environmental requirement is little and highly sensitive photoelectric detection system is provided.
Technical solution of the present utility model is: the utility model is a kind of full-automatic pumping unit of well photoelectric detection system, its special character is: this photoelectric detection system is installed on the flowline exit, comprise photovoltaic element, luminescence unit or reflector element, described photovoltaic element and light source or reflector element are arranged on the light path of photovoltaic element.
Above-mentioned photovoltaic element is a photoelectric probe, and described reflector element is a speculum.
Above-mentioned photovoltaic element is that light source receives head, and described luminescence unit is a light source.
Above-mentioned photoelectric detection system also comprises special air-supply arrangement, as bellows or special air supply duct, forms the positive pressure environment that is slightly larger than external atmosphere pressure around photovoltaic element.
It is fuel-displaced that the utility model is that the mode by optoelectronic induction judges whether, when flowline no liquid medium flowed out, photovoltaic element was for being subjected to light state; When flowline had oil to flow out, light was blocked, and photovoltaic element is the non-light state that is subjected to.The light whether state that is subjected to of this photovoltaic element can be considered as the whether state of extraction oil of oil pumper.Therefore the utlity model has following advantage:
1, working environment requires for a short time, contact with crude oil during photovoltaic element work of the present utility model, and irrelevant with other indexs such as the temperature of going out crude oil, pressure, flow velocity, flows, so working environment and operation condition requirement is little.
2, highly sensitive.The utility model be by photovoltaic element whether for being subjected to light state to judge whether extraction oil, it is highly sensitive.
3, gather degree of accuracy height.The outflow state of oil pipe outlet crude oil and photovoltaic element be subjected to light state directly corresponding, do not have the situation of missing collection substantially.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, among first embodiment of the present utility model in the structure, comprise photovoltaic element 1 and the reflector element 4 that is arranged on photovoltaic element 1 light path, wherein photovoltaic element 1 adopts photoelectric probe, reflector element 4 adopts speculum, and photovoltaic element 1 and reflector element 4 also can adopt other structure of the prior art.During use, both sides below the oil-out 3 of flowline 5 are installed photovoltaic element 1 and reflector element 4 respectively, during the utility model work, photovoltaic element 1 emission optical signal is given reflector element 4, if oil-out 3 belows do not have oil, photovoltaic element 1 can receive the optical signal that is reflected by reflector element 4, at this moment, photovoltaic element 1 produces the photosignal that does not have oil, be passed to the test section of the governor circuit that industrial single-chip microcomputer constitutes, the latter can carry out operational analysis to photosignal, determines that oil extraction system does not have oily normality and goes out oil condition; If there is oil oil-out 3 belows, then can block this optical signal, at this moment, photovoltaic element 1 produces the photosignal of oil, be passed to the test section of the governor circuit that industrial single-chip microcomputer constitutes, the latter can carry out operational analysis to photosignal, has the normality of oil to go out oil condition to determine oil extraction system.
The utility model also can be arranged bellows 2 near oil-out 3, and oil-out 3 sides of photovoltaic element 1 are formed gas curtain, with avoid oil-out 3 because of the ejection liquid water smoke, splash, formation is adhered to and adhesion photovoltaic element 1, prevents that its detection effect and application life to photovoltaic element 1 from exerting an influence.
Among second embodiment of the present utility model in the structure, comprise photovoltaic element and the luminescence unit that is arranged on the photovoltaic element light path, wherein photovoltaic element adopts light source to receive head, luminescence unit adopts light source, mounting means during use is identical with the structure of embodiment one, principle is also identical, receives head by light source and whether can receive the optical signal that light source sends and judge whether fuel-displaced.
