Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning parts of marine scientific research equipment, and in particular to a cleaning device for parts of marine scientific research equipment. BACKGROUND

[0002] Key equipment and components in marine scientific research equipment (such as ROV, AUV, A-frame, crane, ship power equipment and auxiliary equipment, etc.) are exposed to harsh marine environments of high humidity, high temperature, high salt fog and oil-containing pollution for a long time. The surface of the equipment and components is prone to accumulate heavy oil stains, salt, gum and metal dust and other pollutants. These deposits not only accelerate the surface wear of the components, but also cause the heat conduction performance of the components to decrease, resulting in poor heat dissipation, thus reducing the operating efficiency of the mechanical system, and even inducing serious mechanical failure. Therefore, regular and thorough cleaning of the mechanical components of marine scientific research equipment is a key maintenance link to ensure the safe and efficient navigation of marine scientific research equipment.

[0003] The current cleaning method commonly used on marine scientific research equipment has the problem of difficult waste liquid treatment. The cleaning waste liquid contains a large amount of oil stains, chemical cleaning agents and metal particles, and improper treatment will cause significant pollution to the marine environment. At the same time, the existing cleaning process usually relies on a large amount of fresh water, resulting in high fresh water consumption. Under the condition of limited fresh water supply during ocean navigation, the consumption of on-board fresh water reserves is increased, which is not conducive to long-term navigation and green environmental protection requirements. In addition, the existing part cleaning device usually uses independent electric heating or steam heating to heat the cleaning liquid to a suitable temperature, which has high overall energy consumption and is not consistent with the current development direction of green marine scientific research equipment energy saving and emission reduction.

[0018] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. 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.

[0019] In this invention, the terms "comprising," "including," "having," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0020] In this invention, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. Additionally, in this invention, the character " / " generally indicates that the preceding and following related objects have an "and / or" relationship.

[0021] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," "fixed," "combined," "coupled," and "installed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a direct connection or an indirect connection via an intermediate medium; or the internal communication of two components or the interaction between two components. As examples, a direct connection refers to two parts or components being connected together without the need for an intermediate medium, while an indirect connection refers to two parts or components each being connected to at least one intermediate medium, with the connection achieved through the intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. Furthermore, "connected" and "coupled" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0022] In this invention, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the value and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0023] In this invention, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0024] In this invention, the terms "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientations or positional relationships shown in the accompanying drawings. They are used solely for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, in the context, it should be understood that when an element is mentioned as being "upper" or "lower" than another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element.

[0025] Please refer to Figures 1 to 6 As shown, this embodiment provides a cleaning device for marine scientific research equipment parts, including a cleaning mechanism and a filtration mechanism. The cleaning mechanism includes a cleaning tank 1 and a heating component 2. The cleaning tank 1 is used to hold the cleaning fluid and the parts to be cleaned. The inlet end of the heating component 2 is fluidly connected to the outlet end of the cooling water system of the marine scientific research equipment's power unit, and its outlet end is fluidly connected to the inlet end of the cooling water system of the marine scientific research equipment's power unit, forming a heat exchange circulation loop. The heating component 2 is placed in the cleaning tank 1 to heat the cleaning fluid. The filtration mechanism includes a primary filtration component 5, an iron filings filtration component 6, a secondary filtration component 7, an oil sludge filtration component 8, and a suspended solids filtration component 9. Each filtration component is connected in series along the flow direction of the cleaning waste liquid. The inlet end of the primary filtration component 5 is connected to the outlet end of the cleaning tank 1. The cleaning waste liquid treated by each filtration component is discharged from the outlet end of the suspended solids filtration component 9, so that the treated cleaning waste liquid can be recycled and reused and meet marine discharge standards.

[0026] By directly connecting the heating component 2 to the cooling water system of the marine research equipment's power unit, a closed heat exchange loop is formed. This fully utilizes the waste heat generated during the operation of the marine research equipment's power unit to heat the cleaning fluid, saving energy and enhancing the cleaning agent's activity. This avoids the need for separate cleaning fluid heating equipment, effectively reducing overall energy consumption and improving overall energy efficiency. The filtration mechanism adopts a multi-stage series filtration component structure, with corresponding filtration components for different types of pollutants. The cleaning wastewater flows sequentially through primary filtration component 5, iron filings filtration component 6, secondary filtration component 7, oil filtration component 8, and suspended solids filtration component 9 for graded filtration and purification, effectively removing solid impurities, iron filings, oil, and fine suspended solids from the cleaning wastewater. The sequence of each filtration component matches the characteristics of the pollutants, achieving graded treatment and gradual purification, avoiding excessive load and clogging of a single filtration component, thereby improving the overall purification effect and operational reliability of the filtration mechanism. In addition, the clean wastewater after deep treatment by the filtration mechanism can meet the marine discharge standards, reduce the risk of illegal discharge, and meet the development requirements of green marine scientific research equipment and energy conservation and emission reduction. At the same time, the treated clean wastewater can be recycled for parts cleaning or other uses, thereby significantly reducing the freshwater supply needs of marine scientific research equipment, reducing operating costs, and improving the self-sufficiency of marine scientific research equipment during long-term operation.

[0027] like Figure 2 As shown, specifically, a grating plate 3 is installed inside the cleaning tank 1, located above the bottom of the tank, to support the parts to be cleaned. The heating component 2 is positioned between the bottom of the tank and the grating plate 3. The grating plate 3 supports the parts to be cleaned, maintaining a predetermined distance between the parts and the heating component 2, preventing direct contact between the parts and the heating component 2. Simultaneously, the heating component 2 is positioned between the bottom of the tank and the grating plate 3, below the main flow area of ​​the cleaning fluid, which facilitates uniform heating of the cleaning fluid and avoids localized overheating or underheating.

[0028] like Figure 3 As shown, more specifically, the heating assembly 2 includes a heat exchange coil 21 and heat-conducting fins 22. The heat exchange coil 21 is continuously coiled and covers the bottom surface of the pool. Its inlet end and its outlet end both extend through the side wall of the cleaning pool 1 and are sealed to the cleaning pool 1. The heat-conducting fins 22 are disposed on the outer surface of the heat exchange coil 21. The continuous coiling and covering of the bottom surface of the cleaning pool 1 by the heat exchange coil 21 provides a longer flow path for the heat exchange medium flowing in the heat exchange coil 21 within the cleaning pool 1, thereby increasing the heat exchange contact area between it and the cleaning liquid, which is beneficial for fully and stably heating the cleaning liquid. At the same time, the heat-conducting fins 22 disposed on the outer surface of the heat exchange coil 21 further expand the heat transfer area between the heat exchange coil 21 and the cleaning liquid, improve the overall heat exchange efficiency, and accelerate the heating rate of the cleaning liquid.

[0029] Understandably, the heat exchange coil 21 is continuously coiled in an S-shape around the bottom surface of the pool, allowing it to cover most of the bottom area and preventing heat from concentrating in a localized location. This ensures that heat is released evenly on the bottom surface, creating a longer and continuous flow path. The residence time of the heat exchange medium within the coil is increased, resulting in more thorough heat exchange with the cleaning fluid and improving the overall heating effect.

[0030] Furthermore, the inlet end of the heat exchange coil 21 is detachably and sealed to the outlet end of the cooling water system of the marine research equipment power unit, and its outlet end is also detachably and sealed to the inlet end of the cooling water system of the marine research equipment power unit. This allows the heating component 2 to be flexibly connected to the circuit of the cooling water system of the marine research equipment power unit without requiring significant modifications to the original cooling water system of the marine research equipment power unit, thus adapting to different ship types and power units. At the same time, when the heating component 2 needs to be inspected, cleaned, or replaced, the two can be directly disassembled and separated, which helps to shorten maintenance time, reduce maintenance difficulty, and reduce operation and maintenance costs.

[0031] Optionally, the inlet and outlet ends of the heat exchange coil 21 are equipped with flange structures, and the outlet and inlet ends of the cooling water system of the marine scientific research equipment power unit are also equipped with matching flange structures. Through the detachable connection between the flange structures and the matching sealing structure, a stable detachable sealed connection between the heat exchange coil 21 and the cooling water system can be achieved. The sealing structure can be a silicone gasket, which is not specifically limited here.

[0032] like Figure 2 As shown, in some optional embodiments, the cleaning mechanism further includes at least one ultrasonic vibrator 4, which is fixedly installed at the bottom of the pool and used to generate ultrasonic vibrations in the cleaning fluid. The ultrasonic vibrator 4 can generate high-frequency vibrations and cavitation effects in the cleaning fluid, causing the cleaning fluid to generate microbubbles. When these bubbles burst, they generate localized high-temperature and high-pressure impacts, which helps the cleaning fluid penetrate into the pores, gaps, and complex structural surfaces of the parts, removing oil, rust, or microparticles adhering to the surface of the parts, achieving deep cleaning. The ultrasonic vibrator 4 may be, but is not limited to, an ultrasonic transducer, and is not limited thereto.

[0033] For example, the number of ultrasonic vibrating elements 4 can be set to multiple, including but not limited to three, four, or six, etc., and is not limited here.

[0034] Furthermore, the ultrasonic vibrating components 4 are arranged in an array on the bottom of the pool to ensure uniform distribution of ultrasonic vibration and avoid vibration blind spots. This ensures that the cleaning fluid in each location within the cleaning pool 1 can receive effective ultrasonic vibration, achieving a consistent overall cleaning effect.

[0035] In some optional embodiments, a temperature detection device is installed in the cleaning tank 1 to monitor the temperature of the cleaning solution in the cleaning tank 1. The temperature detection device may be, but is not limited to, a thermometer.

[0036] like Figure 4 As shown, in some embodiments, both the primary filtration assembly 5 and the secondary filtration assembly 7 include a housing 51, a baffle ring 52, a filter screen 53, a connecting rod 54, and a housing cover 55. The housing 51 has a first inlet and a first outlet on its side wall for the flow of cleaning waste liquid. The baffle ring 52 is disposed inside the housing 51, and its outer edge is tightly fitted with the inner wall of the housing 51. The baffle ring 52 is arranged at an angle, with its end near the first inlet located below the first inlet and its end near the first outlet located above the first outlet. The filter screen 53 is installed on the baffle ring 52. One end of the connecting rod 54 is connected to the baffle ring 52, and the other end is connected to the housing cover 55. The housing cover 55 is detachably and sealingly connected to the housing 51. The filter screen 53 of the primary filtration assembly 5 has a larger pore size than the filter screen 53 of the secondary filtration assembly 7, so as to achieve step-by-step filtration along the flow direction of the cleaning waste liquid. In this design, the filter screen 53 of the primary filter assembly 5 has a larger pore size than the filter screen 53 of the secondary filter assembly 7, allowing the cleaning waste liquid to undergo coarse filtration followed by fine filtration along the flow direction. The primary filter screen 53 effectively shares the filtration load of the secondary filter screen 53, intercepting large particles of impurities, while the secondary filter screen 53 performs secondary filtration of fine particles, thereby reducing the risk of clogging of the secondary filter screen 53, improving overall filtration efficiency, and ensuring smooth flow of the cleaning waste liquid. The inclined arrangement of the baffle ring 52 helps guide the cleaning waste liquid to flow evenly along the surface of the baffle ring 52, ensuring that the cleaning waste liquid is fully filtered through the filter screen 53 before flowing out from the first outlet. In addition, the cover 55 is connected to the baffle ring 52 via a connecting rod 54 and is detachably connected to the outer shell 51. By lifting the cover 55, the filter screen 53 and the baffle ring 52 can be removed as a whole for cleaning the impurities filtered out or replacing the filter screen 53. The operation is simple, effectively reducing maintenance difficulty and improving maintenance efficiency.

[0037] Furthermore, a sealing ring 56 is provided between the cover 55 and the outer casing 51, which can effectively fill the gap between the cover 55 and the outer casing 51, effectively preventing the leakage of cleaning waste liquid during the filtration process and ensuring that the cleaning waste liquid in the filter assembly flows only through the filter screen 53. The sealing ring 56 may be, but is not limited to, a silicone ring, and is not limited here.

[0038] In addition, one end of the connecting rod 54 can be threaded to the cover 55, and the other end can be threaded to the retaining ring 52, so that the cover 55 and the retaining ring 52 are fixed together by the connecting rod 54, making the assembly and disassembly operations simple and convenient.

[0039] like Figure 5As shown, in some embodiments, the iron filings filter assembly 6 includes a housing 61, a rotating shaft 62, a magnetic separation roller 63, a rotation drive 64, a guide plate 65, a scraper 66, a chip removal pipe 67, and a support frame 68. The housing 61 is arranged horizontally and supported by the support frame 68. The rotating shaft 62 is arranged inside the housing 61 along its central axis, and its two ends are rotatably sealed to the housing 61. The magnetic separation roller 63 is sleeved on the rotating shaft 62, and the output end of the rotation drive 64 is connected to the rotating shaft 62 to drive the rotating shaft 62 to rotate the magnetic separation roller 63. A second inlet and a second outlet are provided on the side wall of the housing 61 below its central horizontal axis. The guide plate 65 is arranged inside the housing 61, one end of which is connected to the second inlet and extends towards the magnetic separation roller 63 along the flow direction of the cleaning waste liquid, and the other end is located below the magnetic separation roller 63 to guide the cleaning waste liquid through the outer working area of ​​the magnetic separation roller 63. Pipe 67 is located on the side wall of housing 61, opposite to the second inlet; one end of scraper 66 is connected to chip removal pipe 67, and the other end abuts against the outer surface of magnetic separation roller 63, used to scrape off iron filings adsorbed on the surface of magnetic separation roller 63 and discharge them along chip removal pipe 67; wherein, the cleaning waste liquid after being treated by primary filter assembly 5 has removed large particulate impurities, and enters the housing 61 of iron filings filter assembly 6 through the second inlet. Under the guidance of guide plate 65, the cleaning waste liquid flows through the outer working area of ​​magnetic separation roller 63. Magnetic separation roller 63 rotates under the drive of rotation drive member 64, adsorbing iron filings in the cleaning waste liquid. After adsorption, the cleaning waste liquid is discharged through the second outlet located below the second inlet; in order to ensure the continuous operation of magnetic separation roller 63, scraper 66 is located on the side wall of housing 61 opposite to the second inlet, one end of which abuts against the outer surface of magnetic separation roller 63 to scrape off the adsorbed iron filings, and the other end is connected to chip removal pipe 67 to discharge the iron filings. With the above structure, the iron filings filter assembly 6 can continuously and stably clean iron filings from the waste liquid, improving filtration efficiency and reducing manual intervention. Furthermore, the rotation drive 64 can, but is not limited to, using a servo motor; no specific limitation is made here.

[0040] Furthermore, the scraper 66 and the chip discharge pipe 67 maintain the same tilt angle, so that the scraped iron chips can smoothly slide along the scraper 66 into the chip discharge pipe 67, realizing gravity-assisted chip discharge, avoiding the accumulation or blockage of iron chips, and ensuring that the surface of the magnetic separation roller 63 remains clean.

[0041] In some embodiments, the oil filtration assembly 8 employs a cyclone oil-water separator. Under a certain pressure difference, utilizing the density difference between oil and water, when the cleaning waste liquid flows through the contraction chamber and tail cone of the cyclone, the centrifugal force generated by the high-speed rotation causes the denser liquid (such as water) to be thrown outwards and discharged from the bottom outlet along a spiral trajectory; while the less dense liquid (such as oil) forms an oil core in the low-pressure area of ​​the tail cone and is discharged from the oil outlet, thereby achieving oil-water separation. Cyclone oil-water separators are existing technology, and their specific structure and working principle are well known in the art, so they will not be described in detail here. Cyclone oil-water separators utilize density difference and centrifugal force, eliminating the need for large settling tanks, occupying little space, and can quickly separate oil and water, improving separation efficiency.

[0042] like Figure 6 As shown, in some embodiments, the suspended solids filtration assembly 9 includes a suspended solids filtration tank 91, which is used to contain and filter the cleaning wastewater treated by the oil filtration assembly 8. An ultrafiltration membrane 92 and a nanofiltration membrane 93 are sequentially arranged within the suspended solids filtration tank 91 along the flow direction of the cleaning wastewater. A drain pipe 94 is sealed to the side wall of the suspended solids filtration tank 91 at the outlet side of the nanofiltration membrane 93. A drain valve 95 is installed on the drain pipe 94 to control the discharge or reuse of the treated cleaning wastewater. The sequential arrangement of the ultrafiltration membrane 92 and nanofiltration membrane 93 within the suspended solids filtration tank 91 along the flow direction of the cleaning wastewater achieves efficient staged filtration. Large suspended solids are first removed by the ultrafiltration membrane 92, and then further removed by the nanofiltration membrane 93 to remove small suspended solids and dissolved impurities, thus achieving step-by-step, fine filtration and improving the purification effect. The combination of the ultrafiltration membrane 92 and the nanofiltration membrane 93 effectively controls the content of suspended solids and small particles in the water, ensuring that the treated cleaning wastewater meets the water quality requirements for subsequent reuse or discharge. In addition, the drain valve 95 can be electrically connected to the controller, thereby realizing the automated control of the start and stop of drainage of the suspended solids filter tank 91.

[0043] like Figure 1 As shown, in some embodiments, the marine scientific research equipment parts cleaning device further includes a connecting assembly 10. The connecting assembly 10 includes a first connecting pipe 101, a second connecting pipe 102, a third connecting pipe 103, a fourth connecting pipe 104, and a fifth connecting pipe 105. The cleaning tank 1, the primary filter assembly 5, the iron filings filter assembly 6, the secondary filter assembly 7, the oil sludge filter assembly 8, and the suspended solids filter assembly 9 are sequentially and sealed together through the first connecting pipe 101, the second connecting pipe 102, the third connecting pipe 103, the fourth connecting pipe 104, and the fifth connecting pipe 105. The above design connects each filter assembly sequentially through each connecting pipe to form a closed and continuous fluid passage, effectively controlling the liquid flow direction, reducing leakage and fluid bypass, ensuring that the clean waste liquid passes through each stage of filtration treatment according to the designed route, and improving filtration efficiency.

[0044] Optionally, a connecting valve 106 is provided near the outlet end of the first connecting pipe 101 to open or close the flow passage between the cleaning tank 1 and the filter assembly, flexibly controlling the flow direction of the cleaning waste liquid. When the device starts or stops, the connecting valve 106 can quickly disconnect or connect the connection between the cleaning tank 1 and the filter assembly, facilitating the emptying, drainage, or maintenance of the cleaning tank 1. The connecting valve 106 can be a solenoid valve, which is not specifically limited here. If a solenoid valve is selected, it can be electrically connected to the controller to realize the automatic control of the start and stop of the water flow in the cleaning tank.

[0045] To optimize the filtration effect of the ultrafiltration membrane 92 and nanofiltration membrane 93 in the suspended solids filtration assembly 9, a lift pump 107 is connected to the end of the fifth connecting pipe 105 near the suspended solids filtration assembly 9. The output end of the lift pump 107 is connected to a lift pipe 108, used to lift the cleaning waste liquid above the suspended solids filtration assembly 9 and inject it into it. By lifting the cleaning waste liquid above the suspended solids filtration assembly 9 through the lift pump 107 and injecting it from above through the lift pipe 108, gravity and pump pressure give the cleaning waste liquid a certain kinetic energy and pressure when entering the ultrafiltration membrane 92 and nanofiltration membrane 93, overcoming membrane surface resistance, improving the staged filtration effect of the ultrafiltration membrane 92 and nanofiltration membrane 93, ensuring uniform liquid flow, and avoiding dead zones or liquid stagnation on the membrane surface. The ultrafiltration membrane 92 is used to retain colloids, large molecular organic matter, and other suspended pollutants, while the nanofiltration membrane 93 further removes dissolved cleaning agent molecules and ions, ensuring that the cleaning waste liquid meets discharge standards.

[0046] The following are the instructions for using a marine scientific research equipment parts cleaning device: First, the cleaning tank 1, primary filter assembly 5, iron filings filter assembly 6, secondary filter assembly 7, oil sludge filter assembly 8, and suspended solids filter assembly 9 are sequentially and sealed together via a first connecting pipe 101, a second connecting pipe 102, a third connecting pipe 103, a fourth connecting pipe 104, and a fifth connecting pipe 105. A connecting valve 106 is installed on the side of the first connecting pipe 101 near the cleaning tank 1, and a lift pump 107 and a lift pipe 108 are connected to the end of the fifth connecting pipe 105 near the suspended solids filter assembly 9. The inlet and outlet ends of the heat exchange coil 21 of the heating assembly 2 are detachably and sealed to the outlet and inlet ends of the cooling water system of the marine scientific research equipment power unit, respectively. Subsequently, with the connecting valve 106 in the closed state, the parts to be cleaned are placed on the grid plate 3 in the cleaning tank 1, and cleaning liquid is injected into the cleaning tank 1 at a level higher than the parts; the cleaning liquid is heated by the heating component 2 until the temperature detection component detects that the cleaning liquid has reached the optimal working temperature; at the same time, the ultrasonic vibration component 4 is activated to perform ultrasonic vibration cleaning on the cleaning liquid. After the parts are cleaned, they are retrieved and the connecting valve 106 is opened, allowing the cleaning waste liquid to flow out of the cleaning tank 1 through the first connecting pipe 101. The waste liquid then undergoes sequential filtration through the primary filter assembly 5, the iron filings filter assembly 6, the secondary filter assembly 7, the oil filter assembly 8, and the suspended solids filter assembly 9. Specifically, the primary filter assembly 5 preferentially intercepts larger particles, the iron filings filter assembly 6 adsorbs ferromagnetic debris from the cleaning waste liquid, the secondary filter assembly 7 performs secondary filtration of fine particles, and the oil filter assembly 8 separates the waste liquid from oil. The treated cleaning waste liquid is then injected into the suspended solids filter tank 91 above the suspended solids filter assembly 9 via the lift pump 107 and lift pipe 108, and flows sequentially through the ultrafiltration membrane 92 and the nanofiltration membrane 93. The ultrafiltration membrane 92 is used to retain colloids, large organic molecules, and other suspended pollutants, while the nanofiltration membrane 93 further removes dissolved cleaning agent molecules and ions, ensuring the cleaning waste liquid meets discharge standards. Finally, the purified cleaning waste liquid is discharged or recycled through the drain valve 95 on the drain pipe 94, thus realizing the reuse of the cleaning liquid.
