[0025] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0026] See Figures 1 to 6The oil mist detection device for hydropower plant environment according to an embodiment of the present invention includes a housing 1, a separation component 2, a collection component 3, a detection component and an exhaust treatment component 4, wherein the housing 1 has an installation cavity.

[0027] Separation component 2 is located within the mounting cavity. Separation component 2 includes a housing 21 and a separation element. The housing 21 has an air inlet, an exhaust outlet, and an oil outlet. The separation element separates oil-mist-containing gas entering the housing 21 through the air inlet. Collection component 3 is located within the mounting cavity at the oil outlet of separation component 2. Collection component 3 collects the oil residue separated by separation component 2. Detection component 1 is located within the housing 1. The detection end of the detection component corresponds to that of collection component 3 to detect the oil residue collected by collection component 3. Exhaust treatment component 4 is located within the mounting cavity at the exhaust outlet of separation component 2 to purify the exhaust gas from separation component 2.

[0028] The oil mist detection device for hydropower plant environment in this embodiment of the invention can separate oil mist and air through the separation component 2, which facilitates the collection of oil mist. The detection component can detect and analyze the collected oil mist to more effectively determine the generation of oil mist and facilitate further maintenance of the equipment based on the detection data. The exhaust treatment component 4 can purify the gas to avoid environmental pollution.

[0029] The structural design of chamber 1 facilitates the integrated installation and maintenance of internal components, while providing a sealed environment for the entire testing process to prevent oil mist leakage from affecting testing accuracy. A separation component 2 is installed on the inner wall of chamber 1, which utilizes the density difference between oil mist particles and air to achieve efficient separation, effectively reducing interference from subsequent tests and improving the measurement accuracy of the testing components. A collection component 3 is installed on one side of chamber 1, enabling automated oil collection and cleaning, avoiding health risks and data errors associated with manual operation, and ensuring the continuity and reliability of the testing process. An exhaust treatment component 4 is installed on the inner wall of one side of chamber 1, which automatically adjusts its position according to the adsorption saturation of the filter material, facilitating replacement and ensuring continuous filtration and stable gas emission quality.

[0030] See Figure 3 and Figure 4 In some embodiments, the separating component is a centrifugal separating device or a collision coalescing device, the axis of the housing 21 has a preset angle with the horizontal plane, the exhaust port is located at one end of the axial direction of the housing 21, the oil drain port is located at the other end of the axial direction of the housing 21, and the oil drain port is located at the lowest end of the inner cavity of the housing 21. Furthermore, an air inlet pipe 22 is connected to the side wall of the housing 21, and the end of the air inlet pipe 22 is configured as an air inlet, with a fan provided at the air inlet.

[0031] The centrifugal separator in this embodiment can be a fan blade or a spiral duct. When high-speed flowing gas enters the housing 21, it can separate oil mist and gas. The collision coalescence device in this embodiment can be multiple baffles. The baffles form a zigzag flow channel inside the housing 21. When oil mist collides with the baffles, it can be adsorbed onto the baffles and then converge at the oil outlet of the collection box. This can efficiently coalesce and separate oil mist particles in the air, improving purification efficiency. The exterior of the housing 21 is installed on the inner wall of the box 1. The stable installation method effectively reduces vibration and noise during equipment operation and improves equipment life. An air inlet pipe 22 is fixedly connected to one side of the housing 21. The end of the air inlet pipe 22 is constructed as an air inlet. A fan can be connected to its inlet to draw in the air to be tested at a constant flow rate, ensuring the representativeness of sampling and separation. An oil drain pipe 23 is fixedly connected to one axial end of the housing 21. The end of the oil drain pipe 23 is constructed as an oil drain port. Its outlet is inclined downward. Using gravity and pressure difference, the condensed liquid oil can automatically and smoothly flow into the collection box 36 below without additional movement. Force; the other end of the housing 21 is fixedly connected to an exhaust pipe 24, the end of which is constructed as an exhaust port to discharge the low oil content gas after preliminary separation, preparing it for the next stage of purification; the separation component 2 is designed with an inclination in the housing 1. By optimizing the inclination angle, the separated liquid is allowed to flow naturally to the oil drain pipe 23 under the action of gravity, avoiding accumulation in the housing 21; the oil drain pipe 23 is lower than the exhaust pipe 24, forming a height difference. This pressure difference design ensures that the separated liquid will not flow back, but will be completely discharged, while the gas is discharged upwards, which conforms to the principle of fluid dynamics.

[0032] In some embodiments, the material collection assembly 3 includes a material collection box 31, a material collection container 36 disposed in the material collection box 31, and a first driving component. The material collection box 31 is provided with a cleaning port 39, and an oil drain port extends into the material collection box 31. The first driving component is connected to the material collection container 36 to drive the material collection container 36 to move. The material collection container 36 has a first position and a second position. In the first position, the material collection container 36 corresponds to the oil drain port and the detection end of the detection component. In the second position, the material collection container 36 can discharge oil stains from the cleaning port 39.

[0033] Furthermore, the top of the collection box 36, and one side of the collection box 36 in the circumferential direction, are open to form a pouring port. The first driving component includes a first driver 34, a partition plate 35, and a second driver 37. The first driver 34 is movable in the vertical direction, and the collection box 36 is rotatably connected to the top of the driving rod of the first driver 34. The partition plate 35 is fixed on the driving rod of the first driver 34 and located below the collection box 36. In the first position, the partition plate 35 is located above the cleaning port 39, and in the second position, the partition plate 35 is located below the cleaning port 39. The second driver 37 is located on the lower side of the partition plate 35, and the driving rod of the second driver 37 slides through the partition plate 35. The upper end of the second driver 37 is rotatably connected to the collection box 36. The driving rod of the second driver 37 is provided with a stop block 38. The second driver 37 is used to control the pouring state of the collection box 36.

[0034] The detection component in this embodiment includes a detector 32 and a detection tube 33. The detector is installed on the collection box 31, and the detection end of the detector 32 extends into the collection box 36 in the first position through the detection tube 33.

[0035] Specifically, the fixed connection between the collection box 31 of the collection assembly 3 and the box body 1 ensures the stability of the structure and forms an independent detection environment, preventing external interference. A detector 32 is installed on one side of the collection box 31. This instrument can quantitatively analyze the concentrated oil mist and output the data in real time, providing accurate data support for environmental monitoring. A detection tube 33 is fixedly connected to one side of the detector 32, shortening the sampling path, reducing sample loss, and ensuring the authenticity of the detection results. A first actuator 34 is installed on the bottom inner wall of the collection box 31. The first actuator 34 can be a cylinder, hydraulic cylinder, or electric actuator. The push rod provides stable and reliable linear power, ensuring accurate execution and repeatability of the tilting action. An isolation plate 35 is fixedly connected to the drive rod of the first driver 34. When lifted, it slides against the inner wall of the collection box 31 to form a sealed detection chamber in the upper part of the collection box 31. When lowered, it drives the movement of subsequent components, realizing reliable switching between collection and discharge states. A collection box 36 is provided on the upper part of the isolation plate 35. The collection box 36 is rotatably connected to the end of the drive rod of the first driver 34. It is specifically used to collect liquid oil mist condensate. The inclined design facilitates the collection of liquid and achieves complete discharge when tilted.

[0036] The second actuator 37 is fixed on the isolation plate 35. The second actuator 37 can be a cylinder, hydraulic cylinder, or electric push rod. The drive rod of the second actuator 37 is rotatably connected to the bottom of the collection box 36, so that the whole can be driven to move up and down synchronously by the first actuator 34. The second actuator 37 can realize the automatic tilting function of the collection box 36. The second actuator 37 is externally fixedly connected to a stop block 38, which reliably maintains the collection box 36 in the collecting state by contacting the isolation plate 35 in the initial position. At this time, the tilting port of the collection box 36 is high, and the collected oil will not flow out from the tilting port. A cleaning port 39 is provided on one side of the collection box 31. Its position is precisely calculated. When the first actuator 34 drives the collection box 36 to move down to the second position, the second actuator 37 controls the collection box 36 to flip, so that the tilting port of the flipped collection box 36 is perfectly connected with the cleaning port 39, ensuring that the oil can be completely discharged into the external collection container without the risk of leakage.

[0037] In this embodiment, the external partition plate 35 is slidably connected to the inner wall of the collection box 31. The high-precision sliding fit ensures both smooth movement and the sealing of the chamber during testing, preventing gas leakage. The external drive rod of the second driver 37 is slidably connected to the through hole of the partition plate 35. The through hole guides the movement of the second driver 37, ensuring that it can move along a predetermined trajectory and eventually trigger the flipping. One side of the abutment block 38 contacts the partition plate 35, thereby cooperating with the second driver 37 to reset the collection box 36, preparing for the next collection.

[0038] See Figure 5 and Figure 6 In some embodiments, a partition 11 is provided inside the housing 1 to define a purification chamber 12 within the mounting cavity. One side of the purification chamber 12 has a purified gas outlet, and an exhaust treatment assembly 4 is disposed within the purification chamber 12. The exhaust treatment assembly 4 includes a first purification component 46, a second driving component, a second purification component 53, and a cleaning plate 52. The second driving component drives the first purification component 46 to move within the purification chamber 12. A pick-and-place port is provided on the side wall of the housing 1, and the second driving component can drive the first purification component 46 to move to the pick-and-place port for maintenance of the first purification component 46 through the pick-and-place port.

[0039] The second purification component 53 is disposed inside the purification chamber 12, and the first purification component 46 and the second purification component 53 are spaced apart in the flow channel between the exhaust port and the purified gas outlet. The cleaning plate 52 is connected to the second driving component to drive the cleaning plate 52 to scrape off the dirt on the second purification component 53. In this embodiment, the first purification component 46 is an activated carbon plate, and one side of the activated carbon plate has a blind hole 48, through which the filter element in the activated carbon plate can be removed; the second purification component 53 is a filter plate, and the cleaning plate 52 is disposed on the side of the filter plate facing the exhaust port.

[0040] Furthermore, the second driving component includes a third driver 41, a support frame 44, a fixed rod 47, a rotating rod, a first connecting rod 43 and a second connecting rod 51. The support frame 44 is slidably disposed on the inner wall of the purification chamber 12 in the vertical direction. The cleaning plate 52 is slidably disposed on the inner wall of the purification chamber 12 in the vertical direction. The first purification component 46 is disposed on the support frame 44. A pressure sensor 45 is provided on the support frame 44. The pressure sensor 45 is used to detect the weight of the first purification component 46 disposed on the support frame 44.

[0041] The fixed rod 47 is fixedly connected to the inner wall of the cleanroom 12. The middle part of the rotating rod is rotatably connected to the fixed rod 47. One end of the rotating rod is connected to the driving end of the third driver 41. The first end of the first connecting rod 43 is connected to the support frame 44. The second end of the first connecting rod 43 is connected to the rotating rod. The first end of the second connecting rod 51 is connected to the cleaning plate 52. The second end of the second connecting rod 51 is connected to the rotating rod.

[0042] The bottom of the third actuator 41 is installed on the bottom inner wall of the housing 1. The third actuator 41 can be a cylinder, a hydraulic cylinder, or an electric push rod. The low center of gravity installation method enhances the stability of the entire adjustment process. A fixed rod 47 is fixedly connected to the inner wall of the housing 1, which provides a solid and unique rotation axis for the rotating plate 42, ensuring the repeatability of each lifting action. The through hole of the rotating plate 42 is rotatably connected to the outside of the fixed rod 47. It can be ensured by bearings or copper sleeves that the rotating plate 42 can rotate flexibly and with low wear around the fixed rod 47.

[0043] The drive end of the third actuator 41 is rotatably connected to a rotating plate 42, which converts the linear thrust of the third actuator 41 into rotational torque. This is the core conversion link for achieving precise angle control of the components. The top of the rotating plate 42 is rotatably connected to a first connecting rod 43. Its length and hinge point are designed to amplify the rotational motion of the rotating plate 42 into the large-stroke lifting motion required by the support frame 44. The top of the first connecting rod 43 is fixedly connected to the support frame 44, whose structure can firmly support the components. Multiple pressure sensors 454 are arrayed on the inner wall of the support frame 44. These sensors can monitor the weight change of the subsequent first purification component 46 in real time and feed the data back to the control system, thereby scientifically judging the adsorption saturation, replacing the traditional rough estimation based on time, and making the replacement timing more accurate. The inner wall of the support frame 44 is equipped with a first purification component 46, which serves as a deep purification unit. It can effectively adsorb residual volatile organic compounds and odors in the gas, ensuring that the final emitted gas is clean and environmentally friendly. A blind hole 48 is provided on one side of the first purification component 46. This design allows the filter element to be hooked out from the outside using a special tool, enabling quick and non-destructive replacement of the filter material and simplifying the maintenance process. A pick-up and drop hole 49 is provided on one side of the housing 1. Its position is aligned with the position of the first purification component 46 after the support frame 44 is lowered, providing convenience for replacement operations without having to open the entire housing 1.

[0044] The second link 51 transmits a portion of the power of the rotating plate 42 to the cleaning plate 52, realizing power reuse and automated cleaning without the need for an additional drive source. The bottom of the second link 51 is rotatably connected to the rotating plate 42, and the position of its hinge point determines the stroke and speed of the cleaning plate 52, maintaining coordination and synchronization with the movement of the first link 43. The top of the second link 51 is rotatably connected to the cleaning plate 52, whose working surface is usually equipped with a scraper or bristles, which can effectively remove dirt from the surface of the second purification component 53 during movement and prevent blockage. The second purification component 53 is fixedly connected to the inner wall of the housing 1, and the gas from the exhaust port must pass through the second purification component 53 and the first purification component 46 before flowing out through the purified gas outlet.

[0045] The second purification component 53 acts as a primary filtration barrier, intercepting larger particles in the gas and protecting the subsequent first purification component 46 from contamination, thus extending its service life. One side of the cleaning plate 52 contacts one side of the second purification component 53, and the constant contact pressure ensures the scraping effect, promptly removing attached impurities and maintaining the low resistance state of the second purification component 53. The cleaning plate 52 is externally slidably connected to the inner wall of the housing 1, and its movement trajectory can be constrained by the design of linear guide rails or grooves, allowing it to reciprocate in a straight line for thorough cleaning.

[0046] The housing 1 is equipped with an inspection door 6, which is correspondingly set with the cleaning plate 52 to clean the dirt cleaned by the cleaning plate 52. Specifically, the top of the housing 1 is detachably connected to the inspection door 6. Opening this door allows for centralized cleaning of dust and impurities scraped off by the cleaning plate 52, and maintenance of the exhaust treatment component 4, making the design more user-friendly.

[0047] An output pipe 7 is provided on one side of the housing 1, and the output pipe 7 is connected to the purified gas outlet; the purified gas can be safely discharged into the atmosphere or sent back to the factory for recycling, and the emissions meet environmental protection requirements.

[0048] Working principle: When the equipment is needed, external air is drawn in by the fan inside the air inlet pipe. The air enters the housing and, under the action of the fan, low-density gas is discharged from the exhaust pipe, while high-density particles are discharged through the oil drain pipe. The oil mist particles discharged through the oil drain pipe will condense into clumps and enter the collection box for collection. The oil mist is detected by a detector and the feedback is displayed on the screen. When it is necessary to treat the oil mist on the collection box, the first drive is activated to retract. The activation of the first drive will drive the isolation plate, collection box and second drive to move downward. Finally, under the action of the second drive, the collection box is pushed, causing the collection box to rotate. The position of the collection box corresponds exactly to the position of the cleaning port, so that the oil on the collection box is discharged through the cleaning port and collected. The exposed collection box facilitates the cleaning of any oil mist that has not been discharged.

[0049] Low-density gas enters the purification chamber on the other side of the enclosure through the exhaust pipe. First, the gas is filtered by the second purification component, and then filtered again by the first purification component before being discharged through the output pipe. The filtration process by the first purification component causes a change in its mass. A pressure sensor at the bottom of the first purification component monitors this change in real time. When the change reaches a preset value, the pressure sensor sends a value back to the controller. The controller then activates the third actuator, which rotates a rotating plate. This rotation moves the first connecting rod, which in turn moves the support frame, thus causing the first... The purification component moves, and when the support frame moves to a position coinciding with the pick-up and drop-off hole, the filter element in the first purification component can be removed through the pick-up and drop-off hole and the blind hole, or the first purification component can be removed entirely. At this time, a new first purification component is inserted into the inner wall of the support frame and installed. Then, the third drive is controlled to push the rotating plate to reset, causing the support frame to move the first purification component upward. As the rotating plate rotates, it drives the second connecting rod to move, and the second connecting rod controls the cleaning plate to slide on the inner wall of the housing. Finally, the movement of the cleaning plate cleans the impurities on the surface of the second purification component, preventing the second purification component from being blocked. When a certain amount of impurities are removed, the inspection door is opened to remove the impurities accumulated inside.

[0050] This invention achieves automated, integrated, and resource-based treatment of oil mist, significantly improving the convenience and safety of equipment maintenance. The equipment actively draws in and separates oil mist using a built-in fan, condensing it and collecting it in a collection box, thus changing the traditional manual cleaning method. When waste oil needs to be treated, the system automatically drives the collection box to flip, precisely discharging the collected liquid oil through a designated cleaning port. This integrated design of "detection-collection-automatic waste discharge" not only avoids secondary pollution and potential safety hazards caused by oil mist settling in the environment, but also effectively recycles oil that would otherwise be wasted. It frees maintenance personnel from heavy, dirty manual wiping and emptying work, greatly improving processing efficiency and operational safety.

[0051] This invention features multi-stage purification and intelligent maintenance, ensuring the cleanliness of gas emissions and simplifying consumable replacement procedures. The device not only handles high-density oil mist but also performs secondary deep purification on the separated low-density gas. The gas passes sequentially through the second and first purification components, ensuring the cleanliness of the final discharged gas. In this embodiment, a pressure sensor monitors the weight change of the first purification component in real time due to adsorption saturation. Once a threshold is reached, a third actuator automatically activates, moving the failed first purification component to a preset pick-and-place port, prompting personnel to replace it. This intelligent monitoring and automated operation ensures the purification system is always in optimal working condition and simplifies the previously cumbersome maintenance process that required experience and periodic disassembly and inspection.

[0052] The highly integrated structure of this invention enables closed-loop management of the entire process from pollution source capture to purification and emission, and possesses a self-cleaning capability. This equipment integrates multiple functions such as oil mist separation, oil collection, automatic oil discharge, gas filtration, consumable status monitoring, and filter cleaning into a compact housing, forming a complete closed-loop treatment system from pollution source capture to final clean emission. Its ingenious design lies in the linkage and reuse of mechanical structures: in the same mechanical action that drives the first purification component to replace, the linked cleaning plate simultaneously scrapes impurities from the surface of the second purification component, completing self-cleaning. This "multi-benefit" linkage design not only optimizes the space layout and reduces the number of driving components, but also ensures the smooth flow of the primary filtration system, further improving the operating efficiency and long-term reliability of the entire system.
