Description

Technical Field

[0001] The present application relates to the technical field of marine engineering equipment, and in particular to an underwater grille cleaning device for a marine water intake cooling source. Background Art

[0002] In the field of marine engineering equipment technology, various marine engineering facilities are facing multiple challenges such as marine biological attachment, corrosion and debris blockage due to long-term immersion in complex marine environments. In particular, the cold source system of nuclear power plants, as a key link in the safe and stable operation of power plants, the steel grids installed in the water inlet flow channel bear the important responsibility of intercepting debris and protecting subsequent equipment. However, since the grids are immersed in seawater for a long time, it is very easy to breed marine organisms and absorb various debris, causing grid blockage, which in turn affects the cold source water intake flow. In severe cases, it may even cause the circulation water pump to shut down, causing immeasurable economic losses.

[0003] At present, the cleaning work on the surface of marine engineering facilities mainly relies on manual cleaning or special cleaning parts designed for specific facilities. Manual cleaning methods are not only labor-intensive and labor-intensive, but also pose personal safety risks, such as accidental injuries that divers may encounter when cleaning with manual shovels. On the other hand, although setting up separate cleaning parts for each facility can improve the cleaning efficiency to a certain extent, this method is costly and the versatility of the parts is extremely poor. It is difficult to adapt to the cleaning needs of grilles of different specifications and different environments, further exacerbating the high cleaning costs and low efficiency.

[0004] Especially in the cleaning of cold source grids in nuclear power plants, the existing methods can no longer meet the actual operation requirements. Manual cleaning by divers is not only inefficient, but also difficult to ensure the timeliness and thoroughness of cleaning. Once the grid is blocked and not discovered and handled in time, it will directly threaten the safe operation of the nuclear power plant. Therefore, the development of an underwater grid cleaning device for the ocean water intake cold source that can clean the grid online, adapt to different equipment specifications, improve cleaning efficiency and reduce costs has become a key issue that needs to be urgently solved in the field of marine engineering equipment technology. Summary of the invention

Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0032] In the field of offshore engineering equipment technology, the cleaning of underwater grilles at the water intake of ocean cooling sources has always been an extremely challenging task. Due to the complexity of the marine environment, the grilles are extremely prone to being attached by marine organisms and blocked by debris, which not only affects the water intake flow of the cooling source system, but may even cause the circulation water pump to stop operating in severe cases, posing a huge threat to the safe and stable operation of key facilities such as nuclear power plants. Traditional cleaning methods, such as manual diving cleaning, not only have a large workload and low efficiency, but also pose significant personal safety risks. Therefore, it is particularly important to develop an efficient, flexible and safe underwater grille cleaning equipment for ocean cooling source water intakes. The underwater grille cleaning equipment for ocean cooling source water intakes introduced in this application is an innovative solution designed to meet this need. It integrates core components such as a bearing bracket, a cleaning device and a driving device, and realizes the precise lifting and movement of the cleaning device through coordinated work to adapt to the cleaning needs of different grilles. The following will introduce the underwater grille cleaning equipment for ocean cooling source water intakes of this application in detail. Please refer to Figures 1 to 4 As shown in Figures 1 to 4 , the underwater grille cleaning equipment for ocean cooling source water intakes of this application includes a bearing bracket 200, a cleaning device 300 and a driving device 400. The bearing bracket 200 is arranged on a fixed component. The bearing bracket 200 includes a movable frame structure. The cleaning device 300 includes a lifting rope 240 and a cable. The cleaning device 300 is arranged on the movable frame structure through the lifting rope 240. The driving device 400 includes a first driving component 410 and a second driving component 420. The first driving component 410 drives the lifting rope 240 to move to drive the cleaning device 300 to lift and lower, and the second driving component 420 drives the bearing bracket 200 to move.

[0033] The device mainly consists of three major parts: a bearing bracket 200, a cleaning device 300, and a driving device 400. Each part works in coordination to jointly achieve the automation and intelligence of cleaning. The entire device is supported and fixed on a component (such as on a civil engineering foundation). The cleaning device can be equipped with a buoyancy balance counterweight to adjust the counterweight of the cleaning device, ensuring the stability and safety of the device underwater. The buoyancy balance counterweight can enhance the stability and wave resistance of the cleaning device, and also optimize the attitude and motion performance. The buoyancy balance counterweight is installed at the bottom or a specific position of the cleaning device to ensure that its weight is evenly distributed. The buoyancy balance counterweight can be moved in position. According to the specific structure of the cleaning device and the cleaning requirements, the buoyancy center and the center of gravity are adjusted to achieve the best balance effect. The counterweight ensures that the floating platform 100 can maintain a stable attitude at a specific water depth and in a marine environment. The design of the buoyancy balance counterweight also takes into account adjustability. For example, by increasing or decreasing the number of counterweights, adjusting the position of the counterweights, or changing the weight of the counterweights, etc., the buoyancy and stability of the cleaning device can be flexibly adjusted, which helps to reduce the cleaning error caused by platform shaking or displacement, improve the accuracy and efficiency of the cleaning operation, enable the cleaning device to maintain an ideal attitude and motion performance underwater, ensure the stable operation state of the floating cleaning device in a harsh marine environment, and reduce the risk of safety accidents caused by platform out-of-control.

[0034] The bearing bracket 200 is set on a fixed component, such as a civil engineering foundation or the floating platform 100, and adopts a movable frame structure, enabling the cleaning device 300 to flexibly adjust its position as needed. It can move freely both horizontally and vertically, thus covering a wider cleaning area. The design of the bearing bracket 200 fully considers the replaceability of the cleaning device 300, especially the replaceability in terms of width and type. Users can quickly replace the cleaning device 300 of different specifications and types according to the actual cleaning requirements to adapt to the grid cleaning tasks of different sizes and different pollution degrees. The mobility of the bearing bracket 200 and the replaceability of the cleaning device 300 enhance the versatility and flexibility of the device, reduce the device maintenance cost, and improve the cleaning efficiency and effect.

[0035] The cleaning device 300 is the part of the equipment that realizes the function of grille cleaning. It is connected to the bearing bracket 200 through the hoisting rope 240 and cables. The hoisting rope 240 is responsible for firmly suspending the cleaning device 300 on the movable frame structure, while the cables undertake the important tasks of transmitting power and signals, including both strong electrical circuits to ensure the power supply of the cleaning device 300 and weak electrical circuits to achieve data transmission and remote control between devices. The cleaning device 300 itself may include various cleaning tools such as cleaning shovels and suction components, and can clean different types of pollutants. The ingenious combination of the cleaning device 300 with the hoisting rope 240 and cables makes the cleaning operation more efficient and accurate, ensuring both the safe operation of the equipment and improving the intelligent level of the cleaning operation.

[0036] The driving device 400, as the power source of the equipment, directly affects the efficiency and effect of the cleaning operation. This device may include a first driving component 410 and a second driving component 420, which drive the movement of the cleaning device 300 and the bearing bracket 200. The first driving component 410 drives the movement of the hoisting rope 240 to drive the cleaning device 300 to achieve the lifting function, enabling it to easily reach different heights of the grille for cleaning. The second driving component 420 can be responsible for driving the movement of the bearing bracket 200, enabling the cleaning device 300 to flexibly adjust its position in the horizontal direction and cover a wider cleaning area. The precise control of the driving device 400 enables the cleaning device 300 to quickly and accurately reach the cleaning position and efficiently complete the cleaning task. The underwater grille cleaning equipment for the ocean water intake cooling source realizes the high efficiency, intelligence and safety of the grille cleaning operation through its ingenious structural design and advanced technology application, providing strong technical support for the maintenance and management of ocean engineering facilities.

[0037] The bearing bracket 200 is further refined in its structural design to include a stable frame system consisting of a suspension beam 220, a cross beam 210 and a longitudinal beam 230, enhancing the overall structural strength and stability of the bearing bracket 200, and also providing an accurate and reliable support foundation for the cleaning device 300 and the hoisting system installed on it. Guide pulleys 221 are carefully configured on the suspension beam 220, and the hoisting rope 240 passes through these guide pulleys 221, forming a set of efficient and smooth hoisting and moving mechanisms. The bearing bracket 200 adopts a combined structure of the suspension beam 220, the cross beam 210 and the longitudinal beam 230 to construct a three-dimensional and high-strength support frame. The suspension beam 220, as the main load-bearing member, has cross beams 210 and longitudinal beams 230 arranged at both ends or key positions, jointly forming a stable support network, which can effectively disperse and bear the loads from the cleaning device 300, the hoisting rope 240 and possible external loads, and can also maintain the stability and anti-deformation ability of the bearing bracket 200 in a complex ocean environment.

[0038] The guide pulley 221 provided on the hanging beam 220 ensures the smoothness and stability of the hoisting rope 240 during movement. The surface of the guide pulley 221 is specially treated to reduce the friction with the hoisting rope 240, thereby extending the service life of the hoisting rope 240 and reducing the energy loss caused by friction. In addition, the position and angle of the guide pulley 221 are carefully calculated to ensure that the hoisting rope 240 can maintain an ideal path during movement, reducing deviation and sway. The hoisting rope 240 can maintain a straight or nearly straight movement state during lifting and horizontal movement, reducing the additional stress and wear caused by a tortuous path. At the same time, the cooperation between the hoisting rope 240 and the guide pulley 221 also ensures the stability and accuracy of the cleaning device 300 during movement.

[0039] The combined structure of the hanging beam 220, the cross beam 210 and the longitudinal beam 230 provides a solid support foundation for the bearing bracket 200, while the guide pulley 221 further ensures the stability and accuracy of the hoisting rope 240 during movement. The setting of the guide pulley 221 makes the hoisting rope 240 move more smoothly, reducing the resistance caused by friction and tortuosity. During cleaning, the cleaning device 300 can reach the designated position faster and can flexibly adjust its position in the horizontal direction, covering a wider cleaning area. It can effectively reduce the cleaning error caused by platform sway or the swing of the hoisting rope 240, improving the accuracy and effect of cleaning. By reducing the friction and wear between the hoisting rope 240 and the guide pulley 221, and optimizing the movement path of the hoisting rope 240, the service life of the hoisting rope 240 and related components can be extended, not only reducing the maintenance cost of the equipment, but also improving the overall reliability and durability of the equipment, and reducing the downtime and maintenance cost caused by equipment failures. The stable structure of the bearing bracket 200 and the smooth hoisting and moving system together provide higher safety and flexibility for the cleaning operation. During the cleaning process, even in the face of harsh marine environments or emergencies, the equipment can maintain a stable operating state, reducing the risk of safety accidents caused by equipment failures or improper operations. At the same time, the flexible movement of the cleaning device 300 also enables the equipment to adapt to the cleaning requirements of grilles of different sizes and shapes, improving the versatility and adaptability of the equipment.

[0040] Specifically, the second driving component 420 can adopt a combined configuration of a vertical movement oil cylinder 421 and a horizontal movement oil cylinder 422 in design, enhancing the moving ability of the bearing bracket 200 and the cleaning device 300 in three-dimensional space and improving the flexibility and accuracy of the cleaning operation. As a key component of the second driving component 420, the vertical movement oil cylinder 421 is mainly responsible for driving the lifting movement of the bearing bracket 200 in the vertical direction. Through the control system, the height of the bearing bracket 200 can be adjusted according to the cleaning requirements, which can assist the cleaning scraper or the suction component to make fine adjustments at different height positions. The horizontal movement oil cylinder 422 is responsible for driving the bearing bracket 200 and the cleaning device 300 to move in the horizontal direction, enabling them to move back and forth in the horizontal plane, so that the cleaning device 300 can cover a wider cleaning area, especially for those grille structures with larger sizes or complex shapes. The combined configuration of the vertical movement oil cylinder 421 and the horizontal movement oil cylinder 422 enables the bearing bracket 200 to achieve omnidirectional movement in three-dimensional space, increasing the coverage of the cleaning operation, and also enables the cleaning device 300 to easily handle various complex-shaped grille structures, improving the cleaning efficiency.

[0041] By precisely controlling the telescopic amounts of the vertical movement oil cylinder 421 and the horizontal movement oil cylinder 422, precise adjustment of the position and posture of the cleaning device 300 can be achieved, enabling the cleaning operation to be customized according to the actual conditions of different grilles, improving the accuracy and effect of the cleaning. At the same time, precise control also reduces the phenomenon of cleaning omissions or over-cleaning caused by improper operation. In the cleaning operation, safety is of utmost importance. The design of the vertical movement oil cylinder 421 and the horizontal movement oil cylinder 422 fully considers safety factors and adopts multiple safety protection measures such as overload protection and limit switches to ensure that no unexpected situations occur during the operation of the equipment. The safety design not only protects the equipment itself from damage but also ensures the safety of the operators.

[0042] In a specific design, the cleaning device 300 can adopt a combination of a cleaning blade and a blade support to achieve the flexible extension or retraction function of the cleaning blade, which can improve the adaptability and efficiency of the cleaning device 300 and enhance its cleaning ability in complex marine environments. As the core component of the cleaning device 300, the cleaning blade is designed with full consideration of the characteristics and cleaning requirements of marine grilles. The blade is made of high-strength and corrosion-resistant materials to ensure that it can remain sharp and durable for a long time in harsh marine environments. The edge of the blade has been specially treated to effectively cut and scrape off marine organisms and debris attached to the grille, ensuring the cleaning effect. The blade support adopts a stable frame design to ensure that the blade maintains a stable posture during the extension or retraction process. The blade support is also equipped with guiding and positioning devices to guide the blade to move along a predetermined path and accurately stay at the required position. Through mechanical design or a hydraulic / pneumatic drive system, the blade can achieve flexible telescopic movement on the blade support. When the grille needs to be cleaned, the blade can quickly extend to cover the surface of the grille; when the cleaning is completed or the position needs to be adjusted, the blade can be easily retracted to avoid interfering with the surrounding environment.

[0043] The flexible extension or retraction function of the cleanable blade enables the cleaning device 300 to quickly adapt to grille structures of different sizes and shapes. During the cleaning process, the blade can closely adhere to the surface of the grille, effectively cutting and scraping off attachments, thereby improving the cleaning efficiency. The moving position mechanism enables the cleaning device 300 to easily cope with various complex marine environments. Whether facing grille gaps of different widths or grille structures of various shapes, the cleaning device 300 can adjust the position and posture of the blade to achieve efficient cleaning. The design of the cleaning blade and the blade support can reduce the maintenance cost of the equipment. Different types of blades can be replaced according to different application scenarios. The blade maintains a stable posture during the extension or retraction process, reducing damage caused by collision or friction. At the same time, the corrosion-resistant material of the blade also extends its service life and reduces the replacement frequency. In addition, the guiding and positioning devices on the blade support also ensure the stability and accuracy of the blade during movement, ensuring that no harm is caused to the operator or the surrounding environment during the extension or retraction of the blade, and further improving the safety of the cleaning operation.

[0044] The cleaning device 300 is designed to not only include a cleaning blade and a blade support, but can also further integrate a suction component to form a more efficient and comprehensive cleaning system. At the same time, a filtering component and a garbage collector are correspondingly equipped on the fixing component to improve the automation level, environmental protection performance, and operation efficiency of the cleaning operation. As an important part of the cleaning device 300, the suction component can suck out marine organisms, sundries, etc. on the surface and gaps of the grille through strong suction. The suction component usually includes a high-performance water pump, a suction pipeline, and a suction head. The suction head can be further designed with special shapes and sizes to ensure that it can closely fit the grille surface and improve the suction efficiency. In addition, the suction component is also equipped with a flow rate and pressure adjustment device to flexibly adjust the suction force according to the cleaning requirements.

[0045] The filtering component on the fixing component is used to process the sucked sewage and sundries, and effectively removes solid particles, suspended solids, and some harmful substances in the sewage by using filtering technology. The garbage collector is used to collect and store the filtered solid garbage and sundries, and usually has a large volume and a reasonable structural layout so as to be able to accommodate a large amount of garbage without easy overflow. The garbage collector can also be equipped with a sealing device and a discharge port to facilitate the treatment of garbage after the cleaning operation is completed and prevent secondary pollution.

[0046] The addition of the suction component enables the cleaning device 300 to simultaneously achieve multiple cleaning functions such as cutting, scraping, and suction, greatly improving the cleaning efficiency. The cooperation of the filtering component and the garbage collector further simplifies the cleaning process, reduces manual intervention, and makes the cleaning operation more efficient and fast. The effective filtration of the filtering component reduces pollution to the marine environment. The easy cleaning and replaceable filter screen design of the filtering component, as well as the large volume and reasonable structural layout of the garbage collector, reduce the maintenance cost of the equipment. At the same time, the flow rate and pressure adjustment device of the suction component also improve the adaptability and flexibility of the equipment, and reduce the additional cost caused by changes in cleaning requirements.

[0047] The cleaning device 300 can also be integrated with an image acquisition component in its design, which can improve the intelligent level of the cleaning operation, enhance the adaptability of the device to complex marine environments and the cleaning efficiency. The image acquisition component usually includes a high-definition camera, an image sensor, and a corresponding image processing unit. The high-definition camera is installed on the cleaning device 300 and can capture the image information of the grille surface and the surrounding environment in real time. The image processing unit then analyzes and processes the collected images in real time to extract useful information, such as the pollution degree of the grille and the distribution of marine organisms. The installation position and angle of the image acquisition component can ensure that the images of the grille surface can be captured comprehensively and accurately. Usually, the camera is installed near the cleaning shovel or the suction component to obtain the images of the grille in real time during the cleaning process. The angle of the camera will also be adjusted according to the structure of the grille and the cleaning requirements to ensure that the most critical image information can be captured.

[0048] The image data collected by the image acquisition component will be transmitted to the control system on the fixed component by wired or wireless means. The control system will further process and analyze these image data and adjust the cleaning strategy according to the analysis results. In addition, the image data can also be stored on a local or remote server for further in-depth analysis and evaluation later. The addition of the image acquisition component enables the device to more intelligently judge the pollution degree and cleaning requirements of the grille, thereby automatically adjusting the cleaning strategy and improving the cleaning efficiency. It can also more accurately understand the structure and pollution situation of the grille, so as to more flexibly adjust the cleaning method and path. The image acquisition component can provide real-time feedback on the cleaning situation of the grille, enabling the operator to timely understand the cleaning progress and effect, which helps the operator to adjust the cleaning strategy in time, avoid repeated cleaning or missed cleaning, thereby improving the cleaning efficiency. It also helps the operator to timely discover potential safety hazards and take corresponding measures to prevent them, ensuring the safe progress of the cleaning operation. The image data collected by the image acquisition component can also provide strong support for subsequent data analysis and decision-making optimization. By analyzing a large amount of image data, the laws and trends of grille pollution can be summarized, providing a basis for formulating more scientific cleaning plans and preventive measures.

[0049] The fixed component can be the floating body platform 100. It should be noted that the fixed component referred to in this application means a component that can fix the bracket relative to the grille. Specifically, it can be set on the civil engineering foundation or a floating body platform with a relatively fixed position. This application preferably uses the floating body platform 100 for the following reasons. The floating body platform can move to different positions and can move to the position of the designated grille. After fixing the floating body platform 100, cleaning can be carried out, so that there is no need to set a cleaning device for each grille device. The floating body platform 100 includes a watertight cabin, an installation part, and a mobile positioning mechanism. The installation part serves as the connection point between the supporting bracket 200 and the floating body platform 100, providing a stable support structure. The floating body platform 100 is also equipped with a mobile positioning mechanism, which can achieve precise control in at least three directions (such as front and back, left and right, up and down) in terms of positioning, enabling the equipment to quickly and accurately reach the grille cleaning position. It can also include an operation console and a detection mechanism, greatly improving the cleaning efficiency and accuracy. The stable support and precise positioning capabilities of the floating body platform 100 provide a reliable working foundation for the entire cleaning equipment, ensuring the smooth progress of the cleaning operation in a complex marine environment.

[0050] Specifically, the mobile positioning mechanism is a hydraulic winch 110, and it also includes a cable cooperating with the hydraulic winch 110. The hydraulic winch 110 is arranged on the floating body platform 100. One end of the cable is connected to the hydraulic winch 110, and the other end is fixedly arranged, improving the positioning accuracy and stability of the underwater grille cleaning equipment in a complex marine environment and greatly enhancing the operation flexibility of the equipment. The hydraulic winch 110 is driven by hydraulic power and can provide a strong and stable traction force. One end of the cable cooperating with the hydraulic winch 110 is firmly connected to the hydraulic winch 110, and the other end is fixedly arranged at a specific part of the underwater grille cleaning equipment or an independent anchor point according to actual needs.

[0051] The way of fixedly setting the other end of the cable can be flexibly adjusted according to the actual situation. It can be directly fixed on the underwater cleaning component to achieve precise traction and positioning for it; it can also be fixed on the anchor point on the seabed. By adjusting the length and tension of the cable, the position of the floating body platform 100 can be stabilized, enabling the hydraulic winch 110 and the cable system to adapt to various complex marine environments and cleaning requirements. The cooperation between the hydraulic winch 110 and the cable system enables the floating body platform 100 to achieve precise positioning and stable attitude maintenance in the marine environment. By precisely controlling the retracting and releasing actions of the hydraulic winch 110, the tension of the cable can be adjusted, thereby achieving fine adjustment of the position of the floating body platform 100 to ensure that the cleaning component can accurately reach the grille position. When impacted by water flow or the grille position changes, the position of the floating body platform 100 can be stabilized by adjusting the tension of the cable to ensure the smooth progress of the cleaning operation. In severe weather or sea conditions, the cable can serve as a safety defense line to prevent the floating body platform 100 from drifting or capsizing due to wind and wave impacts. The precise control of the hydraulic winch 110 also reduces the risk of safety accidents caused by improper operation. The cooperation between the hydraulic winch 110 and the cable system enables the equipment to adapt to various different marine environments and cleaning requirements. Whether it is shallow sea or deep sea operation, whether it is fixed or mobile grille cleaning, precise positioning and stable cleaning operations can be achieved by adjusting the length and tension of the cable and the operating parameters of the hydraulic winch 110. The replacement of the cable and the maintenance of the hydraulic winch 110 can be quickly completed on-site, improving work efficiency.

[0052] More than three hydraulic winches 110 are arranged on the floating body platform 100 and can be distributed in a triangular or polygonal shape to ensure that uniform and strong traction can be provided in all directions, which helps to balance the forces on the floating body platform 100 in the marine environment and reduce the risk of tilting or drifting caused by uneven unilateral forces. The multiple hydraulic winches 110 work together through a control system. According to the actual position and attitude of the floating body platform 100 and the requirements of the underwater cleaning operation, the retracting and releasing speeds and tensions of each can be automatically adjusted to ensure that the floating body platform 100 can maintain a stable attitude and accurately reach the designated position. The configuration of the multiple hydraulic winches 110 improves the maneuverability of the floating body platform 100 in the marine environment. The operator can flexibly adjust the working states of each hydraulic winch 110 according to the actual situation to achieve the rapid movement, precise steering, and stable berthing of the floating body platform 100, which is crucial for coping with changing marine conditions and cleaning requirements.

[0053] To improve the stability of the cleaning device 300, the bearing bracket 200 further includes vertically arranged fixed column structures. The fixed columns are long enough to extend deep underwater. There are two of them and they are arranged in parallel. The fixed columns are usually made of high-strength and corrosion-resistant materials such as stainless steel or special alloys. The top ends of the fixed columns are connected and fixed to the civil engineering foundation or the bearing bracket 200. Tightening mechanisms are provided at both ends of the cleaning device 300 to ensure that the cleaning device 300 does not produce additional displacement during operation. The tightening mechanisms usually include adjustable tightening blocks or tightening wheels that can closely fit on the fixed columns and apply sufficient pressure through hydraulic or mechanical means to firmly fix the cleaning device 300 in the target position. By relatively fixing the cleaning device 300 to the fixed column structure through the tightening mechanism, the stability of the cleaning device 300 during operation can be improved, which helps to reduce the displacement of the cleaning device 300 caused by water flow impact and equipment vibration, thus ensuring the accuracy and efficiency of the cleaning operation. The design of the tightening mechanism usually has a certain degree of adjustability to adapt to fixed column structures of different sizes and shapes, enabling the cleaning device 300 to be flexibly installed on different types of bearing brackets 200, improving the versatility and adaptability of the equipment. Since the cleaning device 300 can maintain a stable position and posture during operation, it can clean the grille more effectively, helping to reduce the situations of missed cleaning and repeated cleaning, and improving the cleaning efficiency and quality.

[0054] Further, a reel 120 can be configured to wind and unwind the pipeline. With the reel 120 equipped, it is specifically used for the winding and unwinding operation of the pipeline. The reel 120 can achieve uniform winding and unwinding of the pipeline, avoiding problems such as winding and knotting of the pipeline during the winding and unwinding process. The pipeline, as an important channel connecting the floating body platform 100 with the underwater cleaning components or sensors, has its material and specifications carefully selected. The specific form can be a cable for transmitting electricity and signals or a conveying pipe for suction. The reel 120 precisely controls the winding and unwinding speed and length of the pipeline according to the requirements of the cleaning operation, monitors the winding and unwinding state of the pipeline in real time through the control system, and makes adjustments according to the actual situation to ensure the smooth progress of the cleaning operation. The use of the reel 120 makes the winding and unwinding operation of the pipeline more convenient and efficient, quickly winding and unwinding the pipeline as needed and coordinating with the adjustment of the position of the underwater cleaning components, thereby improving the cleaning efficiency. The cooperation between the reel 120 and the pipeline enables the equipment to adapt to a variety of different marine environments and cleaning requirements. Whether it is shallow sea or deep sea operation, whether it is necessary to extend the pipeline over a long distance or wind and unwind the pipeline frequently, the reel 120 can provide stable and reliable winding and unwinding support.

[0055] As can be seen from the above, the underwater grille cleaning equipment for the marine water intake cooling source provided by this application can achieve efficient, intelligent and safe underwater grille cleaning operations. It mainly consists of three major parts: a bearing bracket, a cleaning device, and a driving device. The installation part, as the connection point between the bearing bracket and the floating platform, provides stable support. The floating platform is equipped with a mobile positioning mechanism, which can achieve rapid and accurate positioning of the grille cleaning position through precise control in at least three directions (such as front and back, left and right, up and down). It may also include an operation console and a detection mechanism to improve the cleaning efficiency and accuracy, as well as the stable support and precise positioning capabilities, providing a reliable guarantee for the smooth progress of the cleaning operation in a complex marine environment.

[0056] The bearing bracket is set on the fixed component and adopts a movable frame structure, enabling the cleaning device to flexibly adjust its position as needed. It can move freely in both the horizontal and vertical directions, covering a wider cleaning area. The design of the bearing bracket fully considers the replaceability of the cleaning device, especially the replaceability of width and type. Users can quickly replace cleaning devices of different specifications and types according to actual cleaning requirements to adapt to grille cleaning tasks of different sizes and pollution degrees. The mobility of the bearing bracket and the replaceability of the cleaning device enhance the versatility and flexibility of the equipment, reduce the maintenance cost, and improve the cleaning efficiency and effect.

[0057] The cleaning device is connected to the bearing bracket through a hoisting rope and cables. The hoisting rope is responsible for firmly suspending the cleaning device, and the cables undertake the important tasks of transmitting electricity and signals, including strong power lines to ensure power supply and weak power lines to achieve data transmission and remote control. The cleaning device itself may include various cleaning tools such as cleaning scrapers and suction components, which can clean different types of pollutants. The combination of the cleaning device with the hoisting rope and cables makes the cleaning operation more efficient and accurate, ensuring the safe operation of the equipment and improving the intelligent level of the cleaning operation.

[0058] As the power source of the equipment, the performance of the driving device directly affects the efficiency and effect of the cleaning operation. This device includes a first driving component and a second driving component, which respectively drive the movement of the cleaning device and the bearing bracket. The first driving component drives the hoisting rope to move, driving the cleaning device to achieve the lifting function, enabling it to easily reach different heights of the grille for cleaning; the second driving component is responsible for driving the bearing bracket to move, enabling the cleaning device to flexibly adjust its position in the horizontal direction, covering a wider cleaning area. The precise control of the driving device enables the cleaning device to quickly and accurately reach the cleaning position and efficiently complete the cleaning task.

[0059] The load-bearing support includes a suspension beam, a cross beam and a longitudinal beam, forming a stable frame system to enhance the overall structural strength and stability. A guiding pulley is configured on the suspension beam, and the hoisting rope passes through the guiding pulley, forming an efficient and smooth hoisting and moving mechanism, ensuring the smoothness and stability of the hoisting rope during movement, reducing friction, extending the service life, reducing energy loss, and improving the accuracy and efficiency of the cleaning operation.

[0060] The second driving component adopts a combined configuration of a vertical movement oil cylinder and a horizontal movement oil cylinder to enhance the moving ability of the load-bearing support and the cleaning device in three-dimensional space, and improve the flexibility and accuracy of the cleaning operation. By controlling the telescopic amount of the oil cylinder, the position and posture of the cleaning device can be adjusted to adapt to the actual situation of different grilles, improving the cleaning accuracy and effect. The cleaning device can adopt a combination of a cleaning blade and a blade support to realize the flexible extension or retraction function of the cleaning blade, improving the adaptability and efficiency. This design enables the cleaning device to quickly adapt to grille structures of different sizes and shapes, improving the cleaning efficiency, reducing the maintenance cost, and enhancing the safety.

[0061] The cleaning device not only includes a cleaning blade and a blade support, but can also integrate a suction component to form an efficient and comprehensive cleaning system. The floating platform is correspondingly equipped with a filtering component and a garbage collector to improve the automation level, environmental protection performance and operation efficiency of the cleaning operation. The suction component sucks the pollutants on the surface and in the gaps of the grille through strong suction, and is equipped with a flow rate and pressure regulating device to flexibly adjust the suction force. The filtering component processes the sucked sewage and debris, and the garbage collector collects and stores solid garbage and debris. This design enables the cleaning device to have multiple cleaning functions, improving the cleaning efficiency, reducing manual intervention, reducing the maintenance cost, and enhancing the equipment adaptability and flexibility.

[0062] The cleaning device integrates an image acquisition component to improve the intelligent level of the cleaning operation and enhance the adaptability and cleaning efficiency of the equipment to complex marine environments. The image acquisition component includes a high-definition camera, an image sensor and an image processing unit, which can capture the image information of the grille surface and the surrounding environment in real time, and perform real-time analysis and processing. The image data is transmitted to the control system of the floating platform by wired or wireless means for adjusting the cleaning strategy. This design enables the equipment to intelligently judge the pollution degree and cleaning requirements of the grille, automatically adjust the cleaning strategy, improve the cleaning efficiency, provide real-time feedback on the cleaning situation, ensure the operation safety, and provide support for subsequent data analysis and decision optimization.

[0063] The counterweight is installed at the bottom of the cleaning device or a specific position, evenly distributing the weight. Its position can be adjusted according to needs to achieve the best balance effect. The counterweight enhances the stability and wave resistance of the cleaning device, optimizes the attitude and motion performance, reduces the cleaning error, improves the accuracy and efficiency of the cleaning operation, ensures the stable operation of the equipment in the harsh marine environment, and reduces the risk of safety accidents. The mobile positioning mechanism uses a hydraulic winch in cooperation with a cable to improve the positioning accuracy and stability of the equipment in the complex marine environment and enhance the operation flexibility. The hydraulic winch is driven by hydraulic power to provide a strong and stable traction force. One end of the cable is connected to the hydraulic winch, and the other end is fixed according to actual needs. Multiple hydraulic winches are arranged on the floating platform to work together to achieve the rapid movement, precise steering and stable berthing of the floating platform, adapting to the changing marine conditions and cleaning requirements.

[0064] A reel is equipped, which is specifically used for the winding and unwinding operation of the pipeline. The reel can achieve the uniform winding and unwinding of the pipeline, avoiding problems such as entanglement and knotting. The pipeline is an important channel connecting the floating platform and the underwater cleaning components or sensors. Its material and specifications are carefully selected. The reel precisely controls the winding and unwinding speed and length of the pipeline according to the cleaning operation requirements, monitors the winding and unwinding status in real time and adjusts it to ensure the smooth progress of the cleaning operation. The use of the reel makes the winding and unwinding operation of the pipeline more convenient and efficient, improves the cleaning efficiency, and enhances the adaptability of the equipment to different marine environments and cleaning requirements.
