Description

TECHNICAL FIELD

[0001] The present application relates to the field of ship antifouling cleaning technology, in particular to a parallel closed-loop array high-pressure rapid water jet device and a ship cleaning system. BACKGROUND

[0002] Marine biofouling is a significant problem that has long restricted the development of the shipbuilding industry. The attachment behavior of fouling organisms represented by barnacles on the surface of the ship body can significantly increase the sailing resistance, fuel consumption rate and ship body corrosion degree, directly endangering the safe operation of the ship and reducing its economy. According to research reports, the attachment of barnacles can increase the surface roughness of the ship body by more than 30%, causing the sailing resistance to rise by 10% to 40%, and the annual fuel consumption to increase by 15% to 20% additionally, with the global shipping industry incurring an average annual economic loss of more than 10 billion US dollars.

[0003] Traditional antifouling methods have significant limitations: chemical antifouling paint contains heavy metal components, which can easily cause marine environmental pollution, and the coating must be repainted after failure, which is time-consuming and increases costs; manual diving cleaning is inefficient and risky, and is difficult to meet the needs of large-scale fleets; low-speed rotating scrubbing devices can easily damage the ship body coating and do not thoroughly clean complex parts such as curved surfaces. With the increasing strictness of the International Maritime Organization (IMO) on ship environmental protection requirements and the urgent need of the shipping industry to reduce costs and increase efficiency, it is crucial to develop efficient, environmentally friendly and low-damage antifouling technologies.

[0004] Barnacle larvae, especially cyprid larvae, have extremely weak adhesion before fixation, and the impact force of high-pressure water flow is sufficient to remove them from the surface of the ship body; even if a small amount of larvae begin to attach, regular (every 1 to 2 days) high-pressure water injection can also destroy their attachment structure and prevent them from completing the metamorphic development process. The underwater high-pressure water gun system relies on the impact force of high-speed water flow to achieve physical cleaning, has no chemical pollution, causes little damage to the ship body, and can be adapted to an automatic control system to achieve dynamic cleaning of the entire area of the ship body, making it an ideal choice to replace traditional methods, and the design optimization of the system has important practical significance for promoting the development of green shipping. SUMMARY

[0005] In view of the above, to solve the above-mentioned deficiencies of traditional antifouling methods, the present application provides a parallel closed-loop array high-pressure rapid water jet device and a ship cleaning system, which comprises a driving device, a driven device, a plurality of water jet nozzles and a water pipe reel automatic take-up device. The driving device and the driven device are connected to the water jet nozzles to form a parallel closed-loop array high-pressure water jet structure, and the water pipe reel automatic take-up device is used to synchronously take up and pay out the water pipe to enable the water jet nozzles to move along the ship side slide rail to achieve dynamic coverage cleaning. Only filtered seawater is used for physical flushing, and no chemical agents are needed, which is environmentally friendly and non-polluting; and through the symmetrical driving and driven tension balance mechanism, the system can operate stably, comprehensively and automatically in a ship swaying environment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: In a first aspect, a parallel closed-loop array type high-pressure rapid water spraying device includes: Several prime mover parallel components and driven parallel components are connected to multiple multi-hole water sprayers through water pipes to form a parallel closed-loop array high-pressure water spray structure. The driving device drives the automatic hose reel in the prime mover parallel assembly to rotate, and the automatic hose reel in the driven parallel assembly rotates accordingly to maintain the tension balance of the system. A high-pressure water pump supplies water to the water pipe, causing the multi-hole water jet to spray a high-speed water flow.

[0007] Secondly, the present invention also provides a ship cleaning system, including the above-mentioned parallel closed-loop array high-pressure rapid water spray device; The prime mover parallel assembly and the driven parallel assembly are respectively installed at the stern and bow of the ship's deck.

[0008] Compared with the prior art, the present invention has the following beneficial effects: (1) Highly effective antifouling and excellent environmental protection: Through regular, automated high-pressure water jet impact, barnacles can be completely removed before they firmly attach, resulting in a significant and long-lasting antifouling effect. Only seawater is used throughout the process, eliminating chemical agents and completely avoiding the toxic pollution to marine ecosystems caused by traditional antifouling coatings, thus meeting increasingly stringent international environmental regulations.

[0009] (2) Significant economic benefits and operational advantages: Significantly reduce operating costs - reduce fuel consumption (due to increased resistance) and the frequency of expensive dry dock maintenance from the source; save maintenance costs - automated cleaning replaces high-risk and high-cost manual diving operations; extend maintenance cycle - protect the hull coating from mechanical scratching damage, and extend the service life of the coating and the ship.

[0010] (3) High reliability and operational stability: The symmetrical dual-output transmission design ensures dynamic balance of the left and right water pipe retraction and extension forces, greatly improving the system's motion stability, synchronization and overall mechanical reliability under complex sea conditions such as ship swaying.

[0011] (4) Thorough cleaning and strong adaptability: The array-type water sprayers move along the sliding rails to achieve full coverage of the curved surface of the ship without dead angles. The closed-loop control system intelligently adjusts the length of the lead-in and lead-out lines to ensure that different ship types and parts maintain precise cleaning tension and coverage density.

[0012] (5) Intelligentization and integration potential: The system can be seamlessly connected to the ship intelligent management platform, and realize intelligent start-up and shutdown and strategy optimization based on time, speed or biofouling monitoring data, becoming the core technology equipment to promote the intelligent and green operation and maintenance of ships.

[0013] In summary, this invention provides a highly automated ship pollution prevention solution that combines mechanical innovation with biological control strategies, offering high efficiency, environmental friendliness, and economy, and possessing significant industrial application value and broad market prospects.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0016] In the description of this invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, 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.

[0017] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0018] This invention provides a parallel closed-loop array type high-pressure rapid water spraying device, characterized in that it comprises: Several prime mover parallel components and driven parallel components are connected to multiple multi-hole water sprayers through water pipes to form a parallel closed-loop array high-pressure water spray structure. The driving device drives the automatic hose reel in the prime mover parallel assembly to rotate, and the automatic hose reel in the driven parallel assembly rotates accordingly to maintain the tension balance of the system. A high-pressure water pump supplies water to the water pipe, causing the multi-hole water jet to spray a high-speed water flow.

[0019] In this technical solution, the drive unit rotates the automatic hose reel in the prime mover parallel assembly, pulling the hose along. The hose tension is transmitted to the driven parallel assembly, causing its automatic hose reel to rotate passively. Multi-hole sprayers move with the hose, dynamically washing the hull under high-pressure water flow. By combining the prime mover and driven parallel assemblies with multiple multi-hole sprayers, a parallel closed-loop array structure is formed, achieving systematic cleaning of the hull surface. The use of a driven reel design maintains hose tension balance without additional drive, improving system stability. High-pressure water pumps supply water, relying solely on physical water flow for cleaning, avoiding chemical contamination. In this invention, the driving device includes: a motor, a reducer, and a gear transmission assembly; the motor outputs a large torque to the coaxial main gear in the gear transmission assembly via the reducer, and the coaxial main gear meshes with the driven gear in the gear transmission assembly to drive the automatic hose reel take-up device in the prime mover parallel assembly to rotate.

[0020] In this technical solution, the motor output power is reduced in speed and increased in torque by a reducer, driving the coaxial main gear to rotate. The coaxial main gear meshes with the driven gear, transmitting power to the automatic hose reel take-up device to realize the hose reel winding and unwinding actions. The "motor → reducer → gear transmission" transmission chain can output high torque, adapting to the stable driving force required for high-pressure seawater jetting. The gear transmission structure is compact and reliable, suitable for the complex environment of ships.

[0021] In this invention, there are two sets of prime mover parallel components and two sets of driven parallel components, forming two sets of parallel water pipe loops. Each set of water pipe loops connects to multiple orifice sprayers, forming a dynamic cleaning network covering the entire side surface of the ship. The two sets of independent but synchronous water pipe loops are each connected to multiple orifice sprayers; both loops are simultaneously arranged along the side of the ship, together forming a dynamic cleaning network covering the entire side surface of the ship. By setting two sets of prime mover / driven parallel components, a dual-loop cleaning system is formed, expanding the coverage area and improving cleaning efficiency; the dual-loop structure enhances system redundancy and operational continuity.

[0022] In this invention, the driven gears include at least a first driven gear and a second driven gear. The first and second driven gears symmetrically mesh with the coaxial main gear, driving the two coaxial water pipe reel automatic take-up devices in the two prime mover parallel assemblies to achieve synchronous and symmetrical rotation. The first and second driven gears mesh with the left and right sides of the coaxial main gear, respectively; the two driven gears drive the two prime mover parallel assemblies to achieve synchronous and symmetrical rotation. The symmetrical double driven gear design ensures balanced force on both drums, effectively preventing uneven load or jamming caused by unilateral drive; and improves the synchronization and reliability of the system under unsteady conditions such as ship rolling.

[0023] In this invention, the multi-hole water sprayer has a four-way structure and is connected to a water pipe via a four-way pipe connector. The multi-hole water sprayer connects to the water supply pipeline via the four-way pipe connector to achieve water flow distribution and spraying. The four-way structure of the multi-hole water sprayer facilitates connection to multi-directional water pipes, supports array-style layouts, and features a simple structure that is easy to install and maintain.

[0024] In this invention, the water pipe is connected to the multi-hole sprayer after being guided by a pulley. The water pipe changes direction after bypassing the pulley and connects to the multi-hole sprayer; the pulley continuously guides the water pipe path as the sprayer moves. The pulley guidance reduces frictional resistance and wear on the water pipe during its extension and retraction; it also improves the pipe's orientation, preventing tangling or excessive bending, and ensuring smooth water flow and stable sprayer movement.

[0025] The present invention also provides a ship cleaning system, including the above-mentioned parallel closed-loop array high-pressure rapid water spray device; The prime mover parallel assembly and the driven parallel assembly are respectively installed at the stern and bow of the ship's deck.

[0026] In this technical solution, the prime mover parallel assembly is installed at the stern, and the driven parallel assembly is installed at the bow; the two are connected by a water pipe spanning the hull, forming a closed-loop cleaning circuit that runs through the side of the ship. The aforementioned water spray device is integrated into the ship to form a complete self-cleaning system; the symmetrical arrangement of the assemblies at the stern and bow optimizes torque distribution and cleaning coverage.

[0027] In this invention, the multi-hole water jet is arranged on the sidewall of the ship via a fixed slide rail, sliding along the rail to cover the surface of the ship's sidewall. The multi-hole water jet slides along the fixed slide rail on the ship's sidewall under the traction of a water pipe; during movement, it continuously sprays water, covering the entire sidewall area. The arrangement of the multi-hole water jet along the fixed slide rail can adapt to the curved surface of the hull, achieving continuous, thorough cleaning; the sliding structure simplifies motion control and reduces mechanical complexity.

[0028] In this invention, the multi-hole water sprayer has a connecting groove that slides smoothly onto the fixed slide rail. The multi-hole water sprayer body has the connecting groove and is fitted onto the fixed slide rail; the water sprayer slides linearly along the slide rail, powered by a water pipe. The connecting groove structure ensures a reliable sliding fit between the water sprayer and the slide rail, preventing derailment or jamming; it also improves operational stability and long-term reliability.

[0029] In this invention, the prime mover parallel assembly and the driven parallel assembly are installed on the stern and bow of the ship's deck via fixing iron plates. The prime mover parallel assembly and the driven parallel assembly are respectively fixed to the stern and bow decks with iron plate bolts; the iron plates serve as load-bearing bases, transmitting the reaction force of the system during operation to the hull structure. The fixing iron plates rigidly connect the components to the deck, ensuring the device remains stable and does not shift during ship navigation; the installation structure is simple and robust, facilitating on-site construction and subsequent maintenance.

[0030] The technical solution of the present invention will be clearly and thoroughly described below with reference to the accompanying drawings and specific embodiments.

[0031] This embodiment uses two prime mover parallel components (first prime mover parallel component and second prime mover parallel component) and two driven parallel components (first driven parallel component and second driven parallel component) as an example for illustration, as detailed below: The parallel closed-loop array type high-pressure rapid water jet device provided by this invention (see...) Figure 1 The system consists of a prime mover parallel structure 1 (first prime mover parallel assembly 1-1 and second prime mover parallel assembly 1-2), pulleys 3, a multi-hole water jet 4, a high-pressure water pump 5, water pipes 6, and a driven parallel structure 2 (first driven parallel assembly 2-1 and second driven parallel assembly 2-2) connected together. The prime mover parallel structure 1 is fixedly installed at the stern of the ship deck 7-1 via prime mover parallel assembly fixing plate 1-3 and prime mover parallel assembly fixing bolts 1-4. The driven parallel structure 2 is fixedly installed at the bow of the ship deck 7-1 via driven parallel assembly fixing plate 2-3 and driven parallel assembly fixing bolts 2-4.

[0032] In the driving device of the prime mover parallel structure 1, the motor 1-5 drives the reducer 1-6 to output high torque to the coaxial main gear 1-7-1 on the output shaft of the reducer. The first transmission gear 1-7-2 corresponding to the first prime mover parallel assembly 1-1 and the second transmission gear 1-7-3 corresponding to the second prime mover parallel assembly 1-2 are symmetrically located on the left and right sides of the coaxial gear 1-7-1 on the output shaft of the reducer and mesh with it to obtain synchronous and unidirectional motion and power (see...). Figure 5The first transmission gear 1-7-2 is coaxial and connected in series with the first water pipe reel automatic take-up device 1-1-1 of the first prime mover parallel assembly 1-1 and the second water pipe reel automatic take-up device 1-1-2 of the first prime mover parallel assembly 1-1. The first water pipe reel 1-1-1-1 on the first water pipe reel automatic reel and the second water pipe reel 1-1-2-1 on the second water pipe reel automatic reel 1-1-2 are respectively connected to multiple array-type series-arranged multi-hole water jets 4 through pulley guidance. Finally, they are connected to the fifth water pipe reel 2-1-1 and the sixth water pipe reel 2-1-2 of the first driven parallel assembly 2-1 fixed on the ship deck 7-1 to form a closed loop. The fifth water pipe reel 2-1-1 and the sixth water pipe reel 2-1-2 are coaxially connected in series. Similarly, the transmission gear 1-7-3 corresponding to the second prime mover parallel assembly 1-2 is coaxial and connected in series with the third water pipe reel automatic take-up device 1-2-1 on the second prime mover parallel assembly 1-2 and the fourth water pipe reel automatic take-up device 1-2-2 on the second prime mover parallel assembly 1-2; the first water pipe reel automatic take-up device water pipe 1-2-1-1 on the third water pipe reel automatic take-up device 1-2-1 and the fourth water pipe reel automatic take-up device water pipe 1-2-2-1 on the fourth water pipe reel automatic take-up device 1-2-2 are respectively connected to multiple array-type series-arranged multi-hole water sprayers 4 through pulley guidance, and finally... The seventh water pipe reel automatic take-up device 2-2-1 and the eighth water pipe reel automatic take-up device 2-2-2 (the seventh water pipe reel automatic take-up device 2-2-1 and the eighth water pipe reel automatic take-up device 2-2-2 are coaxial and connected in series) in the second driven parallel assembly 2-2 fixed on the ship deck 7-1 to form a closed loop; the high-pressure water pump 5 fills the water pipes of the four reel automatic take-up devices with filtered seawater through water pipes and controls the multi-hole water jet 4 to have a high-pressure and fast water jet; the array multi-hole water jet 4 is installed on the fixed slide rail 7-3 on the side wall of the ship 7 and can move directionally along the fixed slide rail 7-3.

[0033] When the single motor 1-5 outputs high torque to the coaxial main gear 1-7-1 on the output shaft via the reducer 1-6 and rotates clockwise, this gear symmetrically meshes with the double gears on both sides. The first transmission gear 1-7-2 and the second transmission gear 1-7-3 both rotate counterclockwise according to the principle of external gear meshing, thus achieving symmetrical dual-output transmission (see [link]). Figure 1 (As indicated by the arrows), respectively driving the two coaxial water hose reels of the prime mover parallel assembly 1 to rotate counterclockwise, winding up the water hose. Since the water hose is connected to multiple array water jets arranged along fixed slide rails along the ship's sidewall (see...), Figure 2Therefore, the array of water sprayers is simultaneously pulled to slide along the slide rail, and the corresponding automatic hose reel in the driven parallel assembly is pulled to rotate and release the hose while maintaining system tension balance. When the single motor 1-5 outputs a large torque to the coaxial main gear 1-7-1 on the output shaft through the reducer 1-6 and rotates counterclockwise, the gear symmetrically meshes with the double gears, namely the first transmission gear 1-7-2 and the second transmission gear 1-7-3, which both rotate clockwise according to the principle of external gear meshing, realizing symmetrical dual-output transmission. This drives the two coaxial automatic hose reels in the prime mover parallel assembly to rotate clockwise and release the hose. The corresponding automatic hose reel in the driven parallel assembly rotates and winds up the hose while maintaining system tension balance, pulling the multiple array water sprayers 4 connected to the hose to slide along the slide rail. By controlling the forward or reverse rotation of the motor, the reciprocating large-range movement of the parallel closed-loop array high-pressure rapid water sprayer can be controlled.

[0034] The multi-hole water sprayer 4 consists of a four-way pipe connector 4-1, a four-way water pipe connector 4-2, a multi-hole water spray pipe 4-3, a spray nozzle 4-4, and a multi-hole water sprayer housing 4-6 (see...). Figure 3 The multi-hole water sprayer housing 4-6 has a multi-hole water sprayer pipe connection hole 4-7 and a connection groove 4-8 that is connected to the fixed slide groove 7-3 by a sliding pair (see...). Figure 4 Water pipe 6 is connected to four-way pipe connector 4-1 via four-way pipe connector 4-2 through multi-hole water pipe connection hole 4-7 on multi-hole water pipe housing 4-6. The water inlet connected to water pipe 6 is in a straight line with the water outlet of water pipe 6 connected to the next identical multi-hole water pipe 4, and two multi-hole water pipes 4-3 with multiple nozzles 4-4 are connected perpendicularly to it.

[0035] When the high-pressure water pump 5 fills the filtered seawater into the water pipes of the four automatic reel reels through the water pipe 6, the high-pressure water is then sprayed outward through the nozzles 4-4 on the multi-hole water spray pipe 4-3 by multiple series-arranged multi-hole water sprayers 4, forming a specific water spray flow 4-5, and finally realizing multi-directional and multi-point water spraying operation.

[0036] The high-pressure water pump 5 controls the pressure and flow rate of the multi-hole water jet 4, which sprays high pressure and velocity. Targeting the vulnerable window period during the initial attachment phase of barnacle larvae (glandular larvae), the system periodically and automatically sprays high-speed water jets, utilizing water hammer pressure and shear force to destroy or detach their temporary attachment structures. This prevents them from developing into difficult-to-remove adults at the source, transforming high-pressure water cleaning from "post-event cleaning" to "pre-event prevention," achieving the goal of automatic control cleaning for maritime vessels. To further improve the decontamination effect, considering the ship's forward movement and the seawater washing against the side of the ship towards the stern, the multi-hole water jet is configured to spray water in the same direction as the seawater washes, resulting in a more effective combined washing force.

[0037] Below the ship's deck 7-1 and in the outer hull area corresponding to the waterline 7-2, a fixed slide rail 7-3 is pre-installed. A multi-hole water jet 4 is slidably connected to the fixed slide rail 7-3 via a sliding joint through a connecting groove 4-8 on the jet. The jet is then positioned on the ship's sidewall via the fixed slide rail 7-3 and slides along the rail to cover the surface of the ship's sidewall. (See...) Figure 2 and Figure 4 ).

[0038] This invention also designs a symmetrical dual-output force balance structure for both the prime mover parallel assembly and the driven parallel assembly. When the single motor 1-5 outputs a large torque to the coaxial main gear 1-7-1 on the output shaft of the reducer 1-6 and rotates clockwise (see...), Figure 5 The gear consists of two symmetrically meshing gears: a first transmission gear 1-7-2 and a second transmission gear 1-7-3. According to the principle of external gear meshing, both gears rotate counterclockwise. The coaxial main gear 1-7-1 on the reducer's output shaft is the driving gear, and its force direction is opposite to its motion direction. It meshes externally with the first transmission gear 1-7-2. At the meshing point, the force on the coaxial main gear 1-7-1 is downward, while the force on the first transmission gear 1-7-2 is upward. These are action and reaction forces, equal in magnitude and opposite in direction. Similarly, the coaxial main gear 1-7-1 on the reducer's output shaft is also the driving gear, and its force direction is opposite to its motion direction. It meshes externally with the second transmission gear 1-7-3. At the meshing point, the force on the coaxial main gear 1-7-1 is upward, while the force on the second transmission gear 1-7-3 is downward. These are also action and reaction forces, equal in magnitude and opposite in direction. Therefore, it can be seen that the coaxial main gear 1-7-1 on the output shaft of the reducer experiences equal and opposite forces at the meshing point with the two symmetrical external meshing gears, achieving force balance; similarly, the first prime mover parallel assembly 1-1 and the second prime mover parallel assembly 1-2 of the symmetrical dual-output transmission simultaneously wind up the water pipe, experiencing equal and opposite forces, achieving force balance. Likewise, the driven parallel assembly also has a symmetrical dual-output force balance structure (see...). Figure 6 The symmetrical parallel dual-output drive design evenly distributes torque to the two hose reels, fundamentally solving the problems of torque imbalance, asynchronous cable winding and unwinding, and system vibration that are easily caused by single-sided drive. It also ensures dynamic balance of the winding and unwinding forces of the left and right hoses, greatly improving the system's motion stability, synchronization, and overall mechanical reliability under complex sea conditions such as ship swaying.

[0039] In summary, this invention has several innovations: (1) Systemic structural innovation: The system innovatively proposes a parallel closed-loop array design, with parallel closed-loop systems consisting of prime movers and driven components set at the bow and stern respectively. Multiple array water jets arranged along the slide rails form a dynamic cleaning network covering the side surface of the ship. This system integrates the power, transmission, execution and guidance mechanisms into one, realizing the transformation from local cleaning to continuous and collaborative cleaning of the entire side surface of the ship.

[0040] (2) Innovative Transmission Mechanism: Based on the principle of torque balance, a symmetrical dual-output transmission mechanism is proposed. In the prime mover assembly, a transmission path of "single motor → reducer → coaxial main gear → double-sided symmetrical meshing gears" is adopted to achieve symmetrical dual output under a single power source. This design distributes torque evenly to the two water pipe drums, fundamentally solving the problems of torque imbalance, asynchronous winding and unwinding, and system vibration that are easily caused by single-sided drive, and significantly improving transmission stability and reliability.

[0041] (3) Innovative Operation Mode: A preventative physical pollution control method based on biological cycles is proposed, transforming high-pressure water cleaning from a "post-event cleaning" mode to a "pre-event prevention" mode. Its core mechanism lies in precisely targeting the vulnerable window period of barnacle larvae (glandular larvae) during their initial attachment stage. Through regular, automatic spraying of high-speed water, the system utilizes water hammer pressure and shear force to destroy or peel off their temporary attachment structures, thereby preventing them from developing into difficult-to-remove adults at the source. This is an environmentally friendly proactive control strategy.

[0042] (4) Automation and Integration Innovation: The system integrates a high-pressure water pump (for drawing and filtering seawater as a water source), an automatic line winding and unwinding device, and a preset slide rail to form an independently operating self-cleaning unit. This design lays the foundation for integration with the ship's control system, supporting fully automated and unmanned operation on a planned (e.g., every 1-2 days) or on demand (e.g., based on sensor feedback).
