In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. The embodiments described below do not limit the contents of the invention recited in the claims. The entire contents of the configurations shown in the following embodiments are not limited to those required as solutions of the inventions described in the claims.
Referring to fig. 1-4, the apparatus for monitoring the quantity and quality of the terminal oil provided in this embodiment includes:
the oil storage device 1 for storing oil products can be connected with an oil product transport vehicle, namely an oil pipeline of a common oil tank truck, and can also be placed at an oil inlet of an oil depot of a gas station. Between the tank truck and the gas station, i.e. during the transportation of the oil, after the oil enters the oil storage device 1, the oil storage device 1 equivalently provides a static storage space, so as to create a stable state for the subsequent density measurement. Since the density cannot be measured during the flow of the liquid, the measurement can be carried out in a steady state and can also be used during transport.
The oil inlet pipeline 2 and the oil outlet pipeline 3 communicated with the oil storage device 1 are generally provided with flange plates which are respectively connected with the oil inlet pipeline 2 and the oil outlet pipeline 3 through bolts, so that butt joint installation is convenient.
The switch valve 4 is used for opening and closing the oil outlet pipeline 3, so that whether oil is transported outwards or not can be controlled, the oil outlet pipeline 3 is closed during measurement, a relatively stable space is formed in the oil storage device 1, and the oil outlet pipeline 3 is opened after the oil product is qualified and can be outwards output.
The density detection device 5 is used for measuring the density of the oil product in the oil storage device 1, the density is a physical characteristic of a substance and does not change along with the change of the mass, and therefore, the density measurement is more accurate. Because in the transportation, the condition that the oil is polluted by people often appears, someone can take out partial oil, adds water to the residual oil, or mixes other kinds of oil, keeps the tank wagon gross weight unchangeable to weigh unanimously when dispatching a car, check personnel find the weight unchangeable when arriving at the filling station like this, then can think the inspection is qualified. However, this is avoided by measuring the density, which is necessarily caused by the change of density after any substance is mixed, and is revealed during the measurement.
And the controller is in communication connection with both the density detection device 5 and the switch valve 4, and controls the switch valve 4 to be opened and closed according to the measured oil density. When the oil density measured by the density detection device 5 is the same as the preset density, the controller controls the switch valve 4 to be opened, so that qualified oil can flow out; when the oil density measured by the density detection device 5 is different from the preset density, namely is larger than or smaller than the preset density, the controller controls the switch valve 4 to be closed, the oil quality is not over-closed, the outward output is stopped, and whether the pollution conditions such as water adding or mixed loading appear needs to be checked in time. The preset density can be a preset value or a preset range, so that the measured and compared oil products meet the relevant standards, and the use requirements are met within an error range. The controller may be a single chip microcomputer, for example, an STM32 Microcontroller is used as an MCU (micro control Unit) Unit in the present application. The STM32 microcontroller is an existing mature product, and the specific connection structure thereof can refer to corresponding use specifications, including application and installation of related interfaces, corresponding control protocols and the like.
So set up, the mountable is in the position department between the oil-out of tank wagon and the oil depot oil inlet of filling station, the oil stream goes into oil storage device, oil storage device then provides a static stable storage space, the density detection device accuracy of being convenient for measures, when the density of measured oil is unanimous with the density when dispatching a car, the switch valve is opened, can outwards oil delivery, if oil quality does not pass the shut-down then the switch valve closes, stop outwards oil delivery, can effectively avoid appearing artificial morality risk hidden danger if add water, the mixed loading etc.. In the prior art, the gas station judges whether the oil quality reaches the standard or not through the overweight of the wagon balance, and if a transport driver steals oil privately and then adds water and loads the oil in a mixed mode, the wagon balance cannot distinguish whether the actual oil is changed or not when the overall quality is the same as that of departure. Therefore, the oil density is measured by adopting the terminal oil quantity and quality monitoring equipment in the embodiment, the defects can be effectively avoided, and the oil quality is fully ensured, so that the possibility that the oil is polluted in the transportation process in the prior art is solved, the oil quality entering the oil depot of the gas station cannot be guaranteed, even the problem that the oil in the oil depot can be polluted is solved, the oil input is automatically cut off if the quality problem is found when the oil is put in storage, the warning effect is achieved, the quality accident is avoided, the oil quality entering the oil depot of the gas station can be controlled in real time, and the loss caused to enterprises and the bad influence on the society are reduced.

When the medium, namely the oil product, flows through the fork body, the change of the resonant frequency is caused due to the change of the mass of the medium, so that the actual density of the medium is automatically calculated. The shell 9 is an explosion-proof shell, the inside of which is provided with an amplifier, and the outside of which is provided with a wire inlet hole 17 for connecting a cable. The mounting post 10 may be externally threaded for attachment to a mounting flange 11.
