[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0034] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0035] Example 1, reference Figure 1 , which is the first embodiment of the present invention, provides a calibration platform for an oil-water mixing transmitter of a hydropower station. The device includes a calibration unit 100 and an injection unit 200.

[0036] The verification unit 100 includes a stirring tank 101 , a stirring assembly 102 disposed in the stirring tank 101 , and an oil-water mixing transmitter body 103 .

[0037] The injection unit 200 includes an oil inlet pipe 201 and a water inlet pipe 202 which are arranged on the stirring tank 101 .

[0038] Furthermore, it also includes a raw material unit 300, wherein the raw material unit 300 includes an oil storage container 301 and a water storage container 302; the oil inlet pipe 201 is connected to the oil storage container 301; and the water inlet pipe 202 is connected to the water storage container 302.

[0039] The stirring assembly 102 may be made of a rotating shaft rotatably installed in the stirring tank 101 and a motor connected to the rotating shaft. The rotating shaft is provided with blades. The motor drives the rotating shaft and the blades to rotate to stir and mix the inside of the stirring tank 101.

[0040] During use, the oil and water in the oil storage container 301 and the water storage container 302 are introduced into the stirring tank 101, and then stirred and mixed by the stirring component 102, and the oil-water mixing transmitter body 103 verifies the stirred oil-water mixing.

[0041] Example 2, reference Figure 1-Figure 3 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: a two-position two-way solenoid valve 201a is provided on the oil inlet pipe 201; a three-position four-way solenoid valve 202b is provided on the water inlet pipe 202, and a throttle valve 202c connected in parallel with the water inlet pipe 202 is provided between the three-position four-way solenoid valve 202b and the stirring tank 101.

[0042] Furthermore, the calibration platform of the oil-water mixing transmitter also includes common automation components such as single chip microcomputer, precision pressure transmitter, buttons, etc. The calibration platform is mainly composed of two parts: mechanical execution system and electrical control system. Under the precise control of the electrical control system, the mechanical execution system can accurately mix the required oil-water ratio according to the operator's requirements.

[0043] In order to achieve an accurate oil-water ratio, a precision pressure transmitter is installed in the oil storage container 301 and the water storage container 302 respectively to monitor the pressure changes in the oil storage container 301 and the water storage container 302. The single chip microcomputer then converts the pressure signal into a liquid level signal and calculates the change in the liquid volume in the oil storage container 301 and the water storage container 302, thereby achieving an accurate oil-water ratio.

[0044] When measuring a fixed ratio: Taking the 3% oil-water ratio as an example, insert the oil-water mixing transmitter body 103 into the mixing tank 101, and set the alarm value of the oil-water mixing transmitter body 103 to 3%. Press the panel button "3% ratio", confirm the calibration and press the panel "start" button. The two-position two-way solenoid valve 201a is energized, and 100ml of pure oil is first injected into the mixing tank 101 (it can be set in the program according to the size of the mixing tank 101). After the pure oil is injected, reset the two-way solenoid valve excitation, and energize the three-position four-way solenoid valve 202b coil, and inject 3ml of pure water into the mixing tank 101. After the pure water is injected, reset the three-position four-way solenoid valve 202b, and start the stirring component 102 to mix the oil and water evenly, and observe whether the reading of the oil-water mixing transmitter body 103 and the panel 3% alarm indicator light are on; after the calibration is completed, press the "stop" button, the stirring component 102 stops stirring, and the stirring tank 101 is opened to drain the oil.

[0045] When performing data slow change verification: insert the oil-water mixing transmitter body 103 into the stirring tank 101, press the panel button "slow change", and press the panel "start" button after confirming the verification. The two-position two-way solenoid valve 201a is energized, and 100ml of pure oil is first injected into the stirring tank 101 (it can be set in the program according to the size of the stirring tank 101). After the pure oil is injected, the two-way solenoid valve excitation is reset, and the three-position four-way solenoid valve 202b coil is energized, and the stirring motor 102b is started at the same time. Pure water is slowly injected into the stirring tank 101 through the throttle valve 202c. After the verification is completed, press the "stop" button to reset the three-position four-way solenoid valve 202b coil, the motor stops stirring, and the stirring tank 101 is opened to drain the oil.

[0046] The remaining structures are the same as those of Example 1.

[0047] Example 3, reference Figure 1 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the injection unit 200 also includes an oil pump 203 connected to the stirring tank 101, and an oil-water separator 204 connected to the oil pump 203; the oil-water separator 204 is respectively connected to the oil storage container 301 and the water storage container 302.

[0048] After the verification is completed, the oil pump 203 pumps the oil-water mixture in the mixing tank 101 into the oil-water separator 204. After the oil-water mixture is separated by the oil-water separator 204, it is injected into the oil storage container 301 and the water storage container 302 respectively to achieve recycling. When the waste oil remaining in the mixing tank 101 cannot be pumped out, the bottom of the mixing tank 101 is opened for discharge.

[0049] The remaining structure is the same as that of Example 2.

[0050] Example 4, reference Figure 4-Figure 6 , which is the fourth embodiment of the present invention. This embodiment is different from the third embodiment in that: the stirring component 102 includes a stirring shaft 102a rotatably arranged in the stirring tank 101, a stirring motor 102b arranged at the end of the stirring shaft 102a, and a stirring part 102c arranged at the bottom of the stirring shaft 102a.

[0051] The stirring part 102c includes a mounting box 102c-1 arranged at the bottom of the stirring shaft 102a, a mounting plate 102c-2 arranged on both sides of the mounting box 102c-1, and a plurality of stirring blades 102c-3 arranged on the mounting plate; when the stirring motor 102b is working, it can drive the stirring shaft 102a and the mounting box 102c-1 to rotate, thereby driving the plurality of stirring blades 102c-3 on both sides to rotate and mix the oil and water in the stirring tank 101 in the horizontal direction.

[0052] Furthermore, the stirring assembly 102 further includes two mixing parts 102d disposed in the mounting box 102c-1, a driving part 102e disposed on the stirring shaft 102a, and a limiting part 102f disposed between the driving part 102e and the stirring tank 101.

[0053] Among them, the two hybrid parts 102d are respectively arranged at the two ends of the mounting box 102c-1; the hybrid part 102d includes a mounting shaft 102d-1 rotatably arranged on the mounting box 102c-1, a mounting plate 102d-2 arranged at the end of the mounting shaft 102d-1, a hybrid plate 102d-3 arranged in the mounting plate 102d-2, and a gear 102d-4 arranged at the other end of the mounting shaft 102d-1; the gear 102d-4 is located inside the mounting box 102c-1.

[0054] The driving part 102e includes a convex strip 102e-1 arranged on the stirring shaft 102a, a mounting seat 102e-2 outside the sliding device and the convex strip 102e-1, two racks 102e-3 arranged at the bottom of the mounting seat 102e-2, and a spring 102e-4 arranged between the mounting seat 102e-2 and the stirring shaft 102a; the two racks 102e-3 are respectively meshed with two gears 102d-4, wherein when the mounting seat 102e-2 moves downward along the stirring shaft 102a, the spring 102e-4 is compressed, and the racks 102e-3 are meshed with the gears 102d-4. The combination can drive the gear 102d-4 to rotate, thereby driving the mounting shaft 102d-1 and the mounting plate 102d-2 to rotate. The mounting plate 102d-2 rotates in the vertical direction. The position can be converted through multiple mixing plates 102d-3 to mix the top and bottom of the oil-water mixture, which can effectively reduce the influence of the oil and water stratification on the verification result. The mounting plate 1 102c-2 rotating in the horizontal direction and the mounting plate 102d-2 rotating in the vertical direction can oscillate the mixed oil and water, so that the oil-water mixture is mixed in all directions, thereby improving the accuracy of the verification result.

[0055] Furthermore, the limiting portion 102f includes a limiting ring 102f-1 arranged in the top wall of the stirring tank 101, a corrugated groove 102f-2 arranged in the limiting ring 102f-1, a supporting plate 102f-3 arranged in the mounting seat 102e-2, and an extrusion column 102f-4 arranged in the supporting plate 102f-3 and abutting against the corrugated groove 102f-2.

[0056] Among them, under the elastic force of the spring 102e-4, the mounting seat 102e-2 drives the support plate 102f-3 and the extrusion column 102f-4 to resist the corrugated groove 102f-2. When stirring, the extrusion column 102f-4 can rotate with the stirring shaft 102a, the mounting seat 102e-2 and the support plate 102f-3. When the extrusion column 102f-4 rotates along the corrugated groove 102f-2, the extrusion column 102f-4 reciprocates between the trough and the crest of the corrugated groove 102f-2. When the extrusion column 102f-4 is located at the crest, it will press down the support plate 102f-3 and the mounting seat 102e-2. At this time, the spring 1 02e-4 is compressed. When the extrusion column 102f-4 is located at the trough, the spring 102e-4 pops out, and the mounting seat 102e-2 and the support plate 102f-3 are in an upward state. When the height of the mounting seat 102e-2 changes, it can drive the rack 102e-3 to move back and forth, thereby driving the gear 102d-4 and the mounting shaft 102d-1 to move back and forth, and driving the mounting plate 102d-2 and the shaking plate to rotate in the vertical direction. The rotation of the stirring shaft 102a can drive the mounting box 102c-1, the mounting plate 1 102c-2 and the stirring shaft 102a-1 to rotate in different horizontal directions, thereby improving the mixing effect of oil and water.

[0057] Furthermore, the corrugated groove 102f-2 is symmetrically arranged, and two extrusion columns 102f-4 are provided and symmetrically distributed on the support plate 102f-3. The two extrusion columns 102f-4 can synchronously reach the crest or trough of the corrugated groove 102f-2, thereby improving the stability of the downward movement of the support plate 102f-3.

[0058] The remaining structure is the same as that of Example 3.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
