Description

Technical Field

[0001] The utility model relates to the technical field of oil-water volume measurement, in particular to an oil-water volume measuring device for an oil storage tank. Background Art

[0002] Oil storage tanks are often used in oil production and daily processing. Oil storage tanks can be used to hold liquid cargo, such as crude oil or processed oil. By measuring the liquid level in the oil storage tank, the amount of liquid cargo in the oil storage tank can be known. The main methods currently used to measure the volume of oil and fat are pressure sensor method, ultrasonic method, float scale method, liquid level meter method and oil dipstick method. At present, when the existing measuring devices are used, the foam and impact generated after the crude oil or oil enters the oil storage tank will cause the measurement results of the guided wave radar level meter, oil dipstick and pressure sensor to be inaccurate, thereby reducing the detection accuracy of the detection device.

[0003] For example, the utility model patent with publication number CN208187488U discloses an oil storage tank oil volume measuring device, comprising: an oil dipstick; a pendulum arranged at the bottom of the oil dipstick; a dipstick hole arranged at the top of the oil tank, the dipstick hole having an identification portion, the identification portion being used to read the oil dipstick scale value at the position corresponding to the oil dipstick and the dipstick hole; an oil tank empty dipstick volume meter, the oil tank empty dipstick volume meter being used to convert the oil dipstick scale value into the corresponding oil storage volume. When the device is used, the foam and impact generated after crude oil or petroleum enters the oil storage tank will cause the measurement results of the guided wave radar level meter, oil dipstick and pressure sensor to be inaccurate, thereby reducing the accuracy of the detection device. At the same time, the device is more complicated to transmit the detection results, and the staff needs to observe the oil dipstick scale value on the top of the oil tank, thereby reducing the efficiency of the oil storage tank volume detection. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides an oil-water volume measuring device for an oil storage tank, which solves the problem that when the existing measuring device is used, the foam and impact generated after crude oil or petroleum enters the oil storage tank will cause inaccurate measurement results of the guided wave radar level gauge, oil dipstick and pressure sensor, thereby reducing the detection accuracy of the detection device.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: an oil-water volume measuring device in an oil storage tank, comprising an oil storage tank body, a pair of support blocks provided on the side walls of the oil storage tank body, a liquid level bin provided on the support blocks, a liquid level tube provided in the liquid level bin, a liquid inlet pipe provided on the oil storage tank body, the liquid inlet pipe connected to the liquid level tube, an exhaust pipe provided on the oil storage tank body, the exhaust pipe connected to the liquid level tube, a magnetic float slidingly provided in the liquid level tube, a traction rope provided on the magnetic float, a protective bin provided in the liquid level bin, a first guide wheel and a second guide wheel provided in the protective bin, the traction rope provided on the first guide wheel and the second guide wheel, a counterweight block provided on the traction rope.

[0007] Preferably, a resistor is provided in the liquid level bin and between the liquid level tube and the first guide groove, a slide groove is provided on the resistor, and the sliding needle is movably provided on the slide groove.

[0008] Preferably, a wire is provided in the liquid level tank, one end of the wire is connected to the resistor, and the other end of the wire is connected to the metal rod, and a power supply and an ammeter are provided on the wire.

[0010] Preferably, a display screen is provided on the side wall of the liquid level bin.

[0011] Beneficial effects

[0012] The utility model provides an oil-water volume measuring device for an oil storage tank, which has the following beneficial effects:

[0013] When the oil storage tank body of this design is injected with oil, the liquid level in the oil storage tank body rises, and the oil enters the liquid level tube through the liquid inlet pipe, causing the liquid level in the liquid level tube to rise, driving the magnetic float to rise, controlling the movement of the traction rope, causing the counterweight block to drop, and driving the sliding needle to drop. One end of the sliding needle is slidingly set on the slide groove, and the other end of the sliding needle is slidingly set on the metal rod. The size of the resistance can be controlled by moving the sliding needle. According to Ohm's law, in the same circuit, the current passing through a certain section of the conductor is inversely proportional to the resistance of the conductor, that is, I=U / R. The voltage of the power supply is fixed, and the sliding needle moves downward, causing the resistance value of the resistor connected in the circuit to decrease, thereby increasing the current. The ammeter collects the current in the circuit and transmits it to the display screen. The processor in the display screen calculates the height of the oil in the oil storage tank body through the collected current data. The oil storage tank body is a cylindrical container. According to the cylindrical volume calculation formula: V=πr 2 h, where r is the bottom plane radius of the oil storage tank body, and h is the height of the oil in the oil storage tank body. By calculating the volume of oil and water in the oil storage tank body, the liquid level fluctuation in the liquid level tube is small, which can avoid the foam and impact generated after crude oil or petroleum enters the oil storage tank, resulting in inaccurate measurement results, thereby improving the detection accuracy of the detection device.

[0014] The magnetic float of this design rises, causing the permanent magnet in the magnetic float to be transferred to the magnetic indicating unit through magnetic coupling, driving the magnetic indicating unit to flip, and then causing the color of the magnetic indicating unit at the corresponding position of the magnetic float in the local display panel to change, making it easier for staff to observe the position of the magnetic float. The liquid level height in the oil storage tank body can be checked through the scale plate, thereby improving the detection efficiency of the detection device. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] See also Figure 1-6 The utility model provides a technical solution: an oil-water volume measuring device for an oil storage tank, comprising an oil storage tank body 1, a pair of support blocks 2 being provided on the side walls of the oil storage tank body 1, a liquid level bin 4 being provided on the support block 2, a liquid level tube 9 being provided in the liquid level bin 4, a liquid inlet pipe 11 being provided on the oil storage tank body 1, the liquid inlet pipe 11 being connected to the liquid level tube 9, an exhaust pipe 3 being provided on the oil storage tank body 1, the exhaust pipe 3 being connected to the liquid level tube 9, a magnetic float 10 being slidingly provided in the liquid level tube 9, a traction rope 8 being provided on the magnetic float 10, a protection bin 25 being provided in the liquid level bin 4, a first guide wheel 5 and a second guide wheel 13 being provided in the protection bin 25, the traction rope 8 being provided on the first guide wheel 5 and the second guide wheel 13, and a counterweight 17 being provided on the traction rope 8;

[0024] The gravity of the counterweight 17 is less than the gravity of the magnetic float 10. When the oil tank body 1 is filled with oil, the liquid level in the oil tank body 1 rises, and the oil enters the liquid level tube 9 through the liquid inlet pipe 11, causing the liquid level in the liquid level tube 9 to rise, driving the magnetic float 10 to rise, controlling the movement of the traction rope 8, and then causing the counterweight 17 to descend.

[0025] The first guide wheel 5 and the second guide wheel 13 play a guiding role and are used to control the moving direction of the traction rope 8.

[0026] This embodiment is further configured as follows: a first guide groove 18 is provided in the liquid level tank 4, the counterweight block 17 is slidably provided in the first guide groove 18, a sliding needle 16 is provided on the lower wall surface of the counterweight block 17, a second wire groove 24 is provided in the first guide groove 18, the sliding needle 16 is slidably installed in the second wire groove 24, a metal rod 14 is provided in the first guide groove 18, and the counterweight block 17 and the sliding needle 16 are slidably installed on the metal rod 14.

[0027] This embodiment is further configured such that a resistor 15 is provided in the liquid level bin 4 and between the liquid level tube 9 and the first guide groove 18, a slide groove 23 is provided on the resistor 15, and the slide needle 16 is movably provided on the slide groove 23;

[0028] The resistor 15 is coated with insulating paint;

[0030] This embodiment is further configured as follows: a wire 20 is provided in the liquid level tank 4, one end of the wire 20 is connected to the resistor 15, and the other end of the wire 20 is connected to the metal rod 14, and a power supply 19 and an ammeter 21 are provided on the wire 20.

[0031] This embodiment is further configured such that a local display panel 6 is provided on the liquid level bin 4, a plurality of magnetic indicating units 7 are provided on the local display panel 6 and located on one side of the liquid level tube 9, and scale plates 12 are provided on the local display panel 6 and located on both sides of the plurality of magnetic indicating units 7;

[0032] The magnetic indicating unit 7 is rotatably mounted in the local display panel 6, and the two sides of the magnetic indicating unit 7 are different colors, and the axial spacing between the magnetic indicating units 7 is ten millimeters;

[0033] The local display panel 6 is used to locally display the liquid level height in the oil storage tank body 1. When the magnetic float 10 rises, the permanent magnet in the magnetic float 10 is transferred to the magnetic indicating unit 7 through magnetic coupling, causing the magnetic indicating unit 7 to flip, thereby changing the color of the magnetic indicating unit 7 at the corresponding position of the magnetic float 10 in the local display panel 6, making it easier for staff to observe the position of the magnetic float 10. The liquid level height in the oil storage tank body 1 can be checked through the scale plate 12.

[0034] This embodiment is further configured such that a display screen 22 is provided on the side wall of the liquid level bin 4;

[0035] The display screen 22 is used to display the volume of oil and water in the oil storage tank body 1. According to Ohm's law, in the same circuit, the current passing through a certain conductor is inversely proportional to the resistance of the conductor, that is, I = U / R. The voltage of the power supply 19 is fixed, and the sliding needle 16 moves downward, so that the resistance value of the resistor 15 connected in the circuit decreases, thereby increasing the current. The ammeter 21 collects the current in the circuit and transmits it to the display screen 22. The processor in the display screen 22 calculates the height of the oil in the oil storage tank body 1 based on the collected current data. The oil storage tank body 1 is a cylindrical container. According to the cylindrical volume calculation formula: V = πr 2 h, where r is the radius of the bottom plane of the oil storage tank body 1, and h is the height of the oil in the oil storage tank body 1, and the volume of oil and water in the oil storage tank body 1 is calculated.

[0036] Example: When the measuring device is used, when the oil tank body 1 is filled with oil, the liquid level in the oil tank body 1 rises, and the oil enters the liquid level tube 9 through the liquid inlet pipe 11, so that the liquid level of the liquid level tube 9 rises, driving the magnetic float 10 to rise, controlling the movement of the traction rope 8, causing the counterweight 17 to drop, and driving the sliding needle 16 to drop. One end of the sliding needle 16 is slidably set on the slide groove 23, and the other end of the sliding needle 16 is slidably set on the metal rod 14. By moving the sliding needle 16, the size of the resistor 15 can be controlled. According to Ohm's law It can be seen that in the same circuit, the current passing through a certain conductor is inversely proportional to the resistance of the conductor, that is, I = U / R. The voltage of the power supply 19 is fixed, and the sliding needle 16 moves downward, so that the resistance value of the resistor 15 connected in the circuit decreases, thereby increasing the current. The ammeter 21 collects the current in the circuit and transmits it to the display screen 22. The processor in the display screen 22 calculates the height of the oil in the oil tank body 1 based on the collected current data. The oil tank body 1 is a cylindrical container. According to the cylindrical volume calculation formula: V = πr 2 h, where r is the radius of the bottom plane of the oil storage tank body 1, and h is the height of the oil in the oil storage tank body 1. The volume of oil and water in the oil storage tank body 1 is calculated. The local display board 6 is used to locally display the liquid level height in the oil storage tank body 1. The magnetic float 10 rises, and the permanent magnet in the magnetic float 10 is transmitted to the magnetic indication unit 7 through magnetic coupling, causing the magnetic indication unit 7 to flip, thereby changing the color of the magnetic indication unit 7 at the corresponding position of the magnetic float 10 in the local display board 6, making it easier for staff to observe the position of the magnetic float 10. The liquid level height in the oil storage tank body 1 can be checked through the scale plate 12.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
