RU199541U1 - Oil film detector on the water surface - Google Patents

Abstract

The utility model relates to measuring equipment and concerns a detector of an oil film on a water surface. The device can be used to quickly detect the presence of an oil film on the water surface of sea, river and lake waters. To detect oil pollution on the water surface, the detector irradiates the investigated water surface with laser radiation with a wavelength of 512 nm and registers the spectral characteristic of the incoming radiation at the receiver. The claimed detector uses a CCD line as a radiation detector - a photosensitive recording device. The presence of an oil film is determined based on the fact that the intensity values of the incoming optical signal at predetermined wavelengths coincide with the intensity values of the characteristic fluorescence spectrum of a given oil product. Structurally, the detector is made in a housing containing the optics of the systems of excitation and registration of fluorescence, control electronics. The detector is designed for installation on an unmanned aerial vehicle, equipped with an independent power source and a radio module for organizing remote control of the device.

USEFUL MODEL DISCLOSURE

The problem to be solved by the claimed technical solution is to expand the arsenal of technical means in this area, as well as to ensure the autonomy of the means for monitoring the presence of an oil film on the water surface.

To achieve this technical result, an oil film detector on the water surface, containing a module for generating fluorescence exciting radiation with a laser radiation source, an electronic automation and control unit, a fluorescence recording module containing an optical circuit, a photosensitive element and a signal pickup unit, additionally includes a detector housing , as well as a radio module with a remote antenna and a power source containing a rechargeable battery that provides power to the laser radiation source, the electronic automation and control unit and the radio module.

The technical result provided by the above set of features is the possibility of autonomous operation of the device, the possibility of using it as an attachment for an unmanned aerial vehicle.

IMPLEMENTATION OF THE USEFUL MODEL

The device is illustrated in Fig. 1, which schematically shows the device with the cover removed when viewed from above.

The detector includes a detector housing 1, consisting of two covers (not shown in the figure) and a single two-volume part containing a module for generating fluorescence exciting radiation 2, an electronic automation and control unit 3, a battery with a power supply and voltage converters 4, a radio module 5 with a remote antenna 6, a CCD array driver unit with an installed CCD array 7, optical elements of the recording system 8. In this case, the housing has two optical input / output 9 designed to transmit the output laser signal and the input fluorescent signal. The housing also contains two electrical I / O 10, one for the charger plug and one for the power button.

The device works as follows. After pressing the power button and establishing communication with it via the radio channel using the software, the measurement is performed in a single or automatic mode. The measurement takes place by emitting laser radiation and receiving a signal at the input of the fluorescence recording module. Laser radiation is generated and emitted by a laser radiation source controlled by a cable by an electronic automation and control unit and powered by a laser radiation source driver, which in turn is powered by a battery through a voltage converter. When laser radiation hits the oil slick, it causes stimulated fluorescence to propagate in the full solid angle, which causes its presence in the input useful signal in the presence of the oil slick. The input signal enters the photosensitive element, the information from which is processed by the photosensitive element driver unit (CCD array), where the spectral information of the optical signal is read. At the same time, the CCD-line driver unit receives power through the communication cable and power from the electronic automation and control unit. Further, the spectral information in the form of an electrical signal is transmitted through the communication and power cable to the electronic automation and control unit. The electronic automation and control unit receives power from the storage battery through the power converter via the power cable. Based on the spectral information received from the CCD-line driver unit, the electronic automation and control unit, using comparison algorithms, makes a decision on the presence or absence of an oil film on the water surface and transmits this information via a communication and power cable to the radio module, which receives power through the communication cable and power supply from the electronic unit. The radio module generates and transmits an information signal to the control panel via a radio channel using an external antenna of the radio module.
