Description

Technical Field

[0001] This utility model relates to an adaptive oil film detection device, which is mainly used to treat the oily waste generated during the daily operation and maintenance of hydropower station units, and to prevent the oily waste from being discharged into the downstream of the river and causing environmental pollution. Background Technology

[0002] During the operation of a hydropower station, oil sludge is generated in the lubrication and cooling systems of the equipment, and this oil sludge enters the sump. If it is not recycled and treated, it will pollute the water body and harm the surrounding ecological environment. In addition, the accumulation of oil sludge may affect the normal operation of related equipment in the sump, reduce the service life of the equipment, and even cause safety hazards.

[0003] Traditional oil film detection methods, such as visual inspection, can only roughly determine the presence of an oil film and cannot accurately measure key parameters such as its thickness and area, making it difficult to meet the requirements for precise oil recovery. The environment of hydropower station collection wells is complex; water levels fluctuate with water volume, and water quality can be affected by various factors. Traditional detection devices may not be able to adapt to large changes in water level, and detection results are prone to deviation when the water is turbid or contains other impurities. Early detection methods often required periodic manual inspection, making it impossible to monitor the dynamic changes of the oil film in real time. This leads to the inability to detect the formation and development of oil films in a timely manner, missing the optimal time for oil recovery, and hindering the automation of oil recovery control.

[0004] Therefore, to solve the above problems, there is an urgent need for a new type of adaptive oil film detection device. This adaptive oil film detection device can accurately measure oil film parameters and location, adapt to complex environments such as large water level fluctuations and turbid water, achieve real-time transmission of oil film information, and link with recovery equipment to improve automated recovery efficiency, ensure long-term stable operation of the device, and reduce maintenance costs.

[0037] like Figure 1 , Figure 4 As shown, a bracket 10 is fixed at a suitable position on the ground at the wellhead of the hydropower station. The bracket 10 is made of steel and has a hollow internal structure with openings on all six sides. The steel sections on both sides of the bottom plane of the bracket 10 extend horizontally beyond the wellhead and are fixed to the ground, so that the bottom plane of the bracket 10 spans above the wellhead.

[0038] A threaded hole is provided on the top plane of the bracket 10 for fixing the outer cover connecting plate 20 on the top of the bracket 10, and fixing the outer cover 21 above the bracket 10 through the outer cover connecting plate 20; two rectangular holes of different sizes are cut in the outer cover connecting plate 20, and the outer cover 21 surrounds the two rectangular holes.

[0039] like Figure 1 , Figures 5-7As shown, a tripod is fixed to the larger rectangular hole of the outer cover connecting plate 20. The tripod has a horizontally arranged rectangular frame 22 and a vertically arranged upright plate 23. The rectangular frame 22 and the upright plate 23 are fixedly connected to form an L-shape. The horizontal frame and the upright plate 23 are connected by diagonal reinforcing ribs 24 on both sides to form a stable structure. The hollow part of the rectangular frame 22 is aligned with the larger rectangular hole to form a connection. The rectangular frame 22 is then fixed to the outer cover connecting plate 20 by fasteners. The upright plate 23 is located on the dividing line between the two rectangular holes of the outer cover connecting plate 20.

[0040] An oil guide hole 29 is provided on the upright plate 23. An oil receiving box 30 is fixed on one side of the upright plate 23 below the oil guide hole 29. The bottom of the oil receiving box 30 is provided with an oil drain hole 31, which is connected to the sludge transfer pipe 36 via a quick connector. The sludge transfer pipe 36 extends downward from the smaller rectangular hole of the outer cover connecting plate 20 to discharge the collected sludge into the oil storage tank 37. The bottom of the oil storage tank 37 is provided with an air vent valve 38 (e.g., Figure 3 When the oil tank is full, the liquid inside the oil storage tank 37 can be emptied.

[0041] An oil scraper 26 is also provided on the upright plate 23. The oil scraper 26 is arranged in a V-shape and is matched and connected to the lower side of the diamond-shaped oil guide hole 29. Two oil scraper plates 27 are fixed on the oil scraper 26, which are V-shaped and have gaps. A straightening plate 28 is also fixed on the upright plate 23.

[0042] like Figure 6 , Figure 7 , Figure 8 As shown, a fixing plate 25 is fixed on one side of the upright plate 23 for fixing the motor 11. A bearing seat 13 is fixed on the upright plate 23, and a deep groove ball bearing 14 is provided in the bearing seat 13. The motor shaft 12 of the motor 11 is installed in conjunction with the deep groove ball bearing 14, so that the motor shaft 12 passes through the upright plate 23 and extends above the larger rectangular hole. The bearing seat 13 is fixed to the upright plate 23 by four bolts, and two grooves are provided in the middle through hole. The deep groove ball bearing 14 is installed between the two grooves. A retaining ring 15 is provided in each groove to prevent the deep groove ball bearing 14 from axial displacement.

[0043] like Figure 9 , Figure 10As shown, a gear is provided on the motor shaft 12. The gear includes: magnetic rollers 16 at both ends, a toothed steel wheel 17 in the middle, and a bushing 18 between the magnetic rollers 16 and the toothed steel wheel 17. The magnetic rollers 16, bushing 18, and toothed steel wheel 17 are fixed together by bolts. Both ends of the gear are fixed to the motor shaft 12 by tightening screws. One end of the motor shaft 12 passing through the gear is fixed to the mounting block of the rectangular frame 22 by a tail bearing seat 19. The tail bearing seat 19 is fixed by a first support plate 32 and a second support plate 33. The first support plate 32 and the second support plate 33 are connected by bolts and a waist-shaped hole structure to facilitate adjustment of the vertical distance and facilitate installation of the motor shaft 12.

[0044] like Figure 1 , Figure 2 , Figure 3 As shown, a toothed steel belt 34 is installed on the gear. The toothed steel belt 34 has a hollow closed-loop structure. It fits into the straightening plate 28 to form a limit and also passes through the gap between the two oil scraper plates 27. A steel belt guide wheel 35 is fixed at the water collection well below the water surface. The bottom of the toothed steel belt 34 is wrapped around the steel belt guide wheel 35.

[0045] A vertically arranged correction guide rail 39 is fixed on one side of the support 10. The upper end of the correction guide rail 39 is fixed to the support 10, and the lower end extends to the bottom of the water collection well. A sliding sleeve 40 is fitted on the correction guide rail 39. The sliding sleeve 40 contacts the correction guide rail 39 through ball bearings to form rolling friction, thereby reducing friction and making the sliding sleeve 40 slide up and down more smoothly.

[0046] The sliding sleeve 40 is integrally connected to the float plate 41. Each of the four corners of the float plate 41 is provided with a float ball 42. An oil film detector 43 is fixed in the middle of the float plate 41 with bolts. The detection end of the oil film detector extends into the water collection well. The oil film detector is also connected to the ground control system through a connecting line.

[0047] A spring-loaded winch 44 is also provided on the support 10. The spring-loaded winch 44 is fixed to the support 10 with bolts. The steel wire rope 45 wound on the spring-loaded winch 44 extends downward and is fixed with the hook 46 on the float 41.

[0048] The aforementioned guiding rail 39 and sliding sleeve 40 preferably adopt a quadrilateral structure and operate up and down using rolling friction, ensuring smooth up and down movement while preventing radial slippage. Four floats 42 keep the float plate 41 afloat on the water surface and automatically adapt to changes in water level, ensuring the oil film detector 43 remains submerged to detect the oil film thickness. When the detected oil film thickness reaches a set value, the motor 11 automatically starts, driving the gear to rotate. The gear then drives the toothed steel belt 34 to rotate, suspending the sludge oil on the water surface of the collection well onto the steel belt and winding it upwards. Passing the scraper plate 27, the sludge oil is scraped off and enters the oil collection box 30 through the oil guide hole 29, finally flowing into the oil storage tank 37. When the detected oil film thickness is lower than the set value, the motor 11 automatically shuts off, stopping the collection of floating oil, thus fully automating the process.
