Description

Technical Field

[0001] This invention relates to the field of water treatment technology, specifically to a mobile landscape water pollution treatment device. Background Technology

[0002] With the acceleration of urbanization, urban landscape water bodies (such as park lakes, artificial water features, and river landscapes) have become an important part of improving the urban ecological environment and enhancing the quality of life for residents. However, most landscape water bodies are closed or semi-closed systems with weak hydrodynamic conditions and long water exchange cycles. They are susceptible to point source pollution, non-point source pollution, and sediment release, leading to excessive accumulation of nutrients such as nitrogen and phosphorus in the water, causing problems such as eutrophication, black and odorous water, and floating debris accumulation. This not only damages the landscape effect but also threatens the surrounding ecological environment and residents' health. Currently, the treatment of landscape water pollution has become a key task in urban ecological environmental protection, and various treatment technologies and devices have emerged. However, existing technologies still have many shortcomings and are difficult to meet the needs of efficient, flexible, and comprehensive treatment.

[0003] Existing landscape water pollution control devices are mainly divided into two categories: in-situ treatment and ex-situ treatment. Among them, in-situ treatment has become the most widely used method because it does not require the transfer of water bodies and is convenient to construct. However, its core devices and technologies have the following types and defects: First, single-function treatment devices, such as sludge boats and cleaning boats. These devices are designed only for a certain type of pollution problem and cannot achieve comprehensive treatment. When treating landscape water bodies, multiple boats need to be used in rotation, which is inefficient and costly. Second, integrated treatment devices. These devices attempt to integrate multiple treatment functions, but they have problems such as complex structure, poor flexibility, and inconvenient maintenance. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a mobile landscape water pollution treatment device, which solves the problems of existing treatment devices having single functions or complex integration and poor flexibility.

[0005] The technical solution adopted in this invention is as follows: It includes a hull, and further includes a sludge suction component, a conditioning component, an oxygenation component, and a sludge removal component. The sludge suction component, the conditioning component, the oxygenation component, and the sludge removal component are all detachably mounted on the hull and can be modularly disassembled and replaced. A traction component is provided on the hull, and a first buoy is suspended from the traction component. The first buoy and the cutter suction component are fixedly connected. The cutter suction component is used to rotate and crush the sludge and suck it out. The traction component is used to release or lift the first buoy, driving the cutter suction component to move up and down. Drive motors are fixed on both sides inside the first buoy, and the output shaft of the drive motor extends outside the first buoy and is fixed with a propeller.

[0006] The principle of the technical solution: The hull can be a monohull or catamaran; the choice depends on the specific application scenario. Monohulls are suitable for patrolling along inlets and bays, while catamarans are suitable for open waters to increase stability. The hull includes a power system, control system, etc., and serves as the carrier for the entire device, floating on the water and moving the entire device. The suction component, conditioning component, oxygenation component, and cleaning component are all detachably mounted on the hull and can be modularly disassembled and replaced. Users can flexibly select, freely combine, and quickly disassemble and replace components according to the actual treatment needs such as water quality, floating objects, and bottom sediment, without the need for overall hull modification. Furthermore, any functional module can be used individually or in combination according to different working conditions and treatment objectives, achieving multi-purpose functionality and on-demand configuration, significantly improving the applicability, flexibility, and practicality of the equipment, and reducing operation and maintenance costs and equipment redundancy.

[0007] The conditioning component can be a landscape water treatment device, model YC-5500L, and the oxygenation component can be an ozone generator, model FQM-G05. The main principle is an integrated circulating purification process of low-level pumping, mobile biochemical treatment, ozone oxidation, and high-level reflux. First, microorganisms degrade pollutants such as COD, nitrogen, and phosphorus in the water. Then, ozone oxidation further reduces COD, kills algae, and increases dissolved oxygen. Finally, the purified water is returned to the landscape water body to achieve in-situ, efficient, and sustainable water quality improvement. When needed, it can be installed on the hull.

[0008] The aforementioned cleanup component can automatically collect floating debris from the water surface using a front-mounted collection rake and conveyor belt. The debris is then reduced in volume and broken into blocks by a spiral and hydraulic compression mechanism, reducing storage space. During patrol operations, the debris is continuously collected and then transported to shore for harmless treatment after docking. This achieves automatic collection and immediate compression, and is an existing technology, such as the cleanup component used in the small cleanup vessel model FCQM21-20B.

[0009] The traction component is used to release or lift the first pontoon, which carries the sludge suction component and can be square, disc-shaped, or saucer-shaped. The sludge suction component includes a cutter head, a motor driving the cutter head, a sludge pump, and a conveying pipe, etc., and is used to rotate and crush sludge and suck it out. When the traction component releases the first pontoon, the cutter head, motor, and other structures of the sludge suction component are relatively heavy, which can cause the first pontoon to sink. At this time, adjusting the release length of the traction component can change the height of the sludge suction component. Because the cutter head of the sludge suction component is protruding, it is not stable when it contacts the bottom of the water and is very easy to tilt to the side or even lie horizontally on the bottom of the water, in which case it cannot perform its sludge suction function. The first float has an upward tendency and will be positioned above the sluice suction assembly in the water, providing an upward traction force to the sluice suction assembly. This ensures that the cutter head of the sluice suction assembly always faces downwards, even when the traction assembly releases too much force. The drive motors on both sides of the first float drive the propellers on both sides to rotate. By controlling the rotation direction and speed of the two propellers, the float can move forward, backward, and turn in the water, thus adjusting the position of the sluice suction assembly. For example, when both drive motors are rotating clockwise, the first float can be moved forward, thereby pulling the sluice suction assembly. The sluice suction assembly moves; when the two drive motors rotate in opposite directions, they can drive the first pontoon to rotate laterally; and when both drive motors rotate in opposite directions, they can drive the first pontoon to move backward, thereby moving the sluice suction assembly on the seabed. Under the action of the first pontoon, the cutter head of the sluice suction assembly is always facing downward during the movement, effectively slugging in silt. Simultaneously, because the sluice suction assembly is located below, it ensures that the first pontoon maintains a certain distance from the seabed, effectively preventing the propeller from contacting and being damaged. Furthermore, the sluice suction assembly acts like an anchor, preventing the propeller from pulling the first pontoon down when it rotates. The overall tilting or uncontrolled movement improves stability. In practical use, the height of the sluice suction assembly is adjusted using the traction component, and the position of the sluice suction assembly is adjusted using the drive motors on both sides and the propeller. After adjustment, the sluice suction assembly is started with its blades facing downwards, rotating and breaking up the sludge on the bottom surface of the water body and sucking it out. As the sluice suction assembly rotates, it can further extend into the sludge until it contacts the hard rock at the bottom. After the sludge in this area is sucked out, the propeller is used to move and adjust to the next position to suck out the sludge again, avoiding the need to move the hull to adjust the position, thus effectively improving the cleaning efficiency of the bottom sludge.

[0010] Existing cutter suction dredgers have a lever mounted on the bow, which can tilt downwards to allow the cutter head to act on the bottom of the water. The position of the cutter head is then adjusted by moving the hull. Compared with the prior art, the advantages of the present invention are: 1. The present invention utilizes the traction component and the propeller to achieve fine adjustment of the height and horizontal position, thereby eliminating the need to move the hull to adjust the position, improving flexibility, reducing energy consumption, and enabling more precise and rapid suction of sludge from the bottom of landscape water bodies.

[0011] 2. The present invention utilizes a pontoon to make the cutter head of the suction assembly face downwards, which can effectively clean up sludge while also utilizing the floating characteristics of the pontoon to prevent the cutter head from continuously colliding with the hard rock at the bottom, thus avoiding damage to the cutter head.

[0012] 3. The floating box structure of the present invention can both allow the cutter head to contact the bottom of the water and siphon silt, and avoid the cutter head being pressed against the bottom of the water body and causing damage to the bottom structure of the water body, making it more suitable for landscape water bodies.

[0013] 4. In addition to its function of suctioning silt, the suction assembly of the present invention can also provide support and counterweight, thereby improving overall stability.

[0014] In a preferred embodiment of the present invention, the cutter suction assembly includes a cutter suction head and a first mud pump. The cutter suction head is fixed below the first pontoon. The first mud pump is disposed on the hull. The end of the cutter suction head is connected to a conveying pipe, and the first mud pump and the end of the conveying pipe away from the cutter suction head are connected.

[0015] Beneficial effects: The cutter head includes a rotary crushing cutter head and a motor part for driving the cutter head to rotate. It is used to rotary crush sludge and cut it into the cutter head. Then, using the negative pressure of the conveying pipe and the first sludge pump, it is sucked out from the bottom of the water. After being sucked out, it can be transported to the shore or a designated location through a connecting long pipeline. The conveying pipe can be a flexible hose with a certain degree of rigidity, which can suck up sludge while maintaining flexibility, so as to cooperate with the fine adjustment of the position of the first floating box.

[0016] In a preferred embodiment of the present invention, the hull is provided with a moon pool, and the traction assembly includes a base fixed on both sides of the moon pool. A rotating shaft is rotatably provided between the two bases. A winding motor is fixed on the outer side of one of the bases. The output shaft of the winding motor is fixedly connected to the rotating shaft. A traction rope is wound on the rotating shaft. One end of the traction rope is fixedly connected to the rotating shaft, and the other end is connected to the first buoy.

[0017] Beneficial effects: The moon pool is a through hole located in the middle of the hull, penetrating the deck and the bottom of the ship, used to allow the first buoy and the cutter suction assembly to be released downward into the water; the base is used to install the rotating shaft, and the winding motor is used to drive the rotating shaft to rotate, thereby releasing or winding the traction rope, which is connected to the first buoy, thereby releasing or lifting it.

[0018] In a preferred embodiment of the present invention, a buckle is fixed on the side of the traction rope near the first buoy, and a first locking ring is fixed on the upper end of the first buoy.

[0019] Beneficial effects: The latch and the first locking ring cooperate to allow the traction rope and the first float to be quickly connected or unlocked. After unlocking, it can also be connected to other structures, making the first float and the auger assembly a modular structure. It can achieve other functions by quickly changing tools, thus improving practicality. The latch can also be an electronic latch to further improve locking and unlocking efficiency.

[0020] In a preferred embodiment of the present invention, the hull is provided with a transfer trough, and a second mud pump that can slide up and down is provided in the transfer trough, and the second mud pump is connected to a spray pipe.

[0021] Beneficial effects: The transfer trough can be used to house the first sludge pump, allowing the sucked-up sludge to be temporarily placed in the transfer trough for centralized transportation. The second sludge pump can slide up and down using a sliding rail. When it is on the surface of the sucked-up sludge and accumulated water, the second sludge pump and the spray pipe can be used to drain the accumulated water, leaving only sludge, increasing the collection volume and facilitating transportation. When the second sludge pump slides down into the sludge, it can suck up the sludge and spray it to a designated location on the shore, achieving the effect of rapid sludge transfer. Compared with long pipelines, it is more efficient, does not require pre-laying, and saves manpower.

[0022] In a preferred embodiment of the present invention, the hull is further provided with a sliding groove, in which a slidable placement frame is provided, the placement frame being slidably spanning the moon pool; an installation groove is provided below the first pontoon, the installation groove corresponding to the placement frame.

[0023] Beneficial effects: The chute is used to place the placement frame and restrict its sliding direction and distance. The placement frame is normally located in the chute on the hull, at which time the first buoy and the cutter suction assembly can be released or pulled up normally. After the first buoy and the cutter suction assembly are pulled up above the placement frame, the placement frame can be slid across the moon pool. By manually adjusting the position of the first buoy so that the mounting slot below it corresponds with the placement frame, the lock can be released to realize the recovery of the first buoy and the cutter suction assembly.

[0024] In a preferred embodiment of the present invention, a second pontoon is placed on the placement frame, an ultrasonic measuring instrument is provided below the second pontoon, and a second locking ring is fixed above the second pontoon.

[0025] Beneficial effects: The second pontoon is used to mount the ultrasonic mapping instrument and can be quickly connected to the traction rope through the second locking ring, thereby being released into the water. The second pontoon allows the ultrasonic mapping instrument to face downwards. The ultrasonic mapping instrument emits high-frequency ultrasonic pulses into the water and receives the reflected echoes. Combined with precise time difference calculation and depth measurement, it can detect the topographic undulations, sludge thickness, and obstacle distribution at different locations on the water bottom in real time and with high precision, thereby generating a complete and clear 3D underwater topographic map. This topographic map can intuitively present the real shape of the water bottom and the sludge accumulation, providing accurate data support for subsequent dredging operations, helping to determine the dredging scope, plan the cleaning route, and identify key cleaning areas, greatly improving the efficiency, accuracy, and targeting of sludge cleaning.

[0026] In a preferred embodiment of the present invention, a cylinder is provided on the hull, the cylinder is horizontally placed on the side of the slide groove, and its piston rod is fixedly connected to the placement frame.

[0027] Beneficial effects: The cylinder is used to push out the placement frame and can limit the placement frame as it slides across the moon pool, thereby improving its stability.

[0028] In a preferred embodiment of the present invention, a Beidou navigation and positioning module is also included; the Beidou navigation and positioning module is used to acquire the position information of the hull in real time, and the communication module is used to receive the operating range or navigation route information sent by an external terminal.

[0029] Beneficial effects: By using the Beidou navigation and positioning module to obtain the ship's position information in real time, and combining it with the operation range or navigation route set by the external terminal received by the communication module, the ship can automatically navigate to the area to be cleaned according to the preset path, achieving the effect of automatic cruise after setting the range or route.

[0037] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0038] Example 1

[0039] As attached Figure 1 As shown, this invention provides a mobile landscape water pollution treatment device, comprising a hull 1. The hull 1 includes a power system, a control system, etc. The hull 1 can be a monohull or a catamaran. The monohull type is suitable for patrol operations in narrow waters such as shallow waters and bays along the shore, and has the characteristics of maneuverability and flexibility. The catamaran type is suitable for operations in open waters, and has the characteristics of good stability and strong load-bearing capacity. Those skilled in the art can choose the appropriate hull form according to the actual operating water conditions. Its specific structure and drive method are all existing technologies and will not be described in detail here. The power system of the hull 1 is fully electric, and its electrical energy comes from solar energy and / or wind energy. Solar photovoltaic panels can be optionally installed on the hull 1 to absorb solar energy and convert it into electrical energy, and / or wind power generation devices can be installed to generate electricity using wind energy. Both or one of them provides energy for the propeller drive device and various actuators on the hull 1. Excess electrical energy can be stored in a battery. This power system has the characteristics of being clean and environmentally friendly and having flexible energy sources. Its specific structure and working principle are all existing technologies in the art and will not be described in detail here.

[0040] The hull 1 is also equipped with a Beidou navigation and positioning module. The Beidou navigation and positioning module obtains the hull's position information in real time. Combined with the operation range or navigation route set by the external terminal received by the communication module, the hull can automatically navigate to the area to be cleaned according to the preset path, and achieve the effect of automatic cruise after setting the range or route.

[0041] The hull 1 can also be equipped with a sludge suction component, a conditioning component, an oxygenation component, and a flotation component. All of these components can be detachably installed on the hull 1 and can be modularly disassembled and replaced. Users can flexibly select, freely combine, and quickly disassemble and replace them according to the actual treatment needs of the water quality, floating objects, and bottom sediment on site, without the need for overall hull modification. Users can use any functional module individually or in combination according to different working conditions and different treatment objectives, realizing multi-purpose use and on-demand configuration, significantly improving the applicability, flexibility, and practicality of the equipment, and reducing operation and maintenance costs and equipment redundancy.

[0042] The conditioning component can be a landscape water treatment device, model YC-5500L, and the oxygenation component can be an ozone generator, model FQM-G05. The main principle of water conditioning and oxygenation is an integrated circulating purification process of low-level pumping, mobile biochemical treatment, ozone oxidation, and high-level reflux. First, microorganisms degrade pollutants such as COD, nitrogen, and phosphorus in the water. Then, ozone oxidation further reduces COD, kills algae, and increases dissolved oxygen. Finally, the purified water is returned to the landscape water body to achieve in-situ, efficient, and sustainable water quality improvement. When needed, it can be installed on the hull.

[0043] The hull 1 serves as the carrier for the entire device, floating on the water and driving the entire device to move. The hull 1 has a moon pool 10, and a traction assembly 2 is mounted on the moon pool 10. The traction assembly 2 includes bases 11 fixed on both sides of the moon pool 10, and a rotating shaft 12 rotatably connected between the two bases 11. A winding motor 13 is fixed to the outer side of one of the bases 11, and the output shaft of the winding motor 13 is fixedly connected to the rotating shaft 12. A traction rope 14 is wound on the rotating shaft 12, with one end of the traction rope 14 fixedly connected to the rotating shaft 12 and the other end fixed with a buckle 15. The moon pool 10 is a through hole located in the middle of the hull 1, penetrating the deck and the bottom of the hull. The bases 11 are used to mount the rotating shaft 12, and the winding motor 13 is used to drive the rotating shaft 12 to rotate, thereby releasing or winding the traction rope 14. The traction rope 14 is connected to the buckle 15, and the buckle 15 is used to connect with other tools to achieve the effect of releasing or winding.

[0044] As attached Figures 2-4As shown, in this embodiment, the latch 15 is connected to a first locking ring 16, and a first float 3 is fixed below the first locking ring 16. A suction assembly 4 is located below the first float 3. The first float 3 carries the suction assembly 4. When the traction assembly 2 releases the first float 3, the suction assembly 4, due to the weight of its blades, motor, and other structures, can cause the first float 3 to sink. Adjusting the release length of the traction assembly 2 at this time can change the height of the suction assembly 4. Because the blades of the suction assembly 4 are protruding, they are unstable when in contact with the bottom surface, easily tilting or even lying horizontally on the bottom, thus failing to suction silt. The first float 3, however, has an upward tendency and will be positioned above the suction assembly 4 in the water, providing an upward traction force to the suction assembly 4. The cutter head of the suction assembly 4 is always facing downwards, ensuring that the cutter head remains downwards even when the traction rope 14 is released excessively. The suction assembly 4 is used to rotate and crush sludge and suck it out. The suction assembly 4 includes a suction cutter head 7 and a first sludge pump 8. The suction cutter head 7 is fixed below the first pontoon 3. The first sludge pump 8 is mounted on the hull 1. The end of the suction cutter head 7 is connected to a conveying pipe 9. The first sludge pump 8 and the end of the conveying pipe 9 away from the suction cutter head 7 are connected. The suction cutter head 7 includes a rotating and crushing cutter head and a motor part that drives the cutter head to rotate. It is used to rotate and crush sludge and trap it inside the cutter head. Then, using the negative pressure of the conveying pipe 9 and the first sludge pump 8, it is sucked out from the bottom of the water. After being sucked out, it can be transported to the shore or a designated location through a connecting long pipeline.

[0045] As attached Figure 4As shown, in this embodiment, drive motors 5 are fixed on both sides inside the first float 3. The output shafts of the drive motors 5 extend outside the first float 3 and are fixed with propellers 6. The drive motors 5 are used to drive the propellers 6 on both sides to rotate. By controlling the rotation direction and speed of the two propellers 6, the float can be moved forward, backward, and turned in the water, thereby adjusting the position of the sluice suction assembly 4. For example, when both drive motors 5 rotate clockwise, the first float 3 can be moved forward, thereby pulling the sluice suction assembly 4 to move; when the two drive motors 5 rotate clockwise and counterclockwise, the first float 3 can be moved backward. The lateral rotation; when both drive motors 5 reverse, the first float 3 can be driven backward, thereby moving the sluice suction assembly 4 on the bottom of the water. Under the action of the first float 3, the cutter head of the sluice suction assembly 4 is always facing downward during the movement, slugging silt. At the same time, since the sluice suction assembly 4 is located below, the first float 3 can always maintain a certain distance from the bottom surface, which can effectively prevent the propeller 6 from contacting the bottom surface and being damaged. The sluice suction assembly 4 can also act as an anchor, preventing the propeller 6 from causing the first float 3 to flip over or move uncontrollably when it rotates, thereby improving stability.

[0046] As attached Figure 2 As shown, in this embodiment, the hull 1 is provided with a transfer trough 17, in which a second mud pump 18 that can slide up and down is provided. The second mud pump 18 is connected to a spray pipe 19. The transfer trough 17 can be used to place the first mud pump 8, so that the sucked-out sludge is temporarily placed in the transfer trough 17 for centralized transfer. The second mud pump 18 can slide up and down. A slide rail can be set on the inner wall of the transfer trough 17 to install the second mud pump 18 on the slide rail. Then, a hoisting rope is set. The hoisting rope can be manually pulled to adjust the height of the second mud pump 18. Then, the hoisting rope is fixed to the deck of the hull 1 for fixation. When it is on the surface of the sucked-out sludge and water, the second mud pump 18 and the spray pipe 19 can be used to drain the water, leaving only sludge, increasing the collection volume and facilitating transfer. The second mud pump 18 slides down into the sludge and can suck out the sludge and spray it to a designated location on the shore to achieve the effect of rapid sludge transfer. Compared with long pipes, it is more efficient, does not require pre-laying, and saves manpower.

[0047] When using this device to clean the sludge at the bottom of a landscape water body, the height of the cutter head 7 is adjusted using the rotating shaft 12 and the traction rope 14. The horizontal position of the cutter head 7 is adjusted using the drive motors 5 and the propellers 6 on both sides of the first float box 3. After adjustment, the motor of the cutter head 7 is started to rotate and break up the sludge on the bottom surface of the water body. The first mud pump 8 and the conveying pipe 9 are used to suck it out. When the cutter head 7 rotates, it can further extend into the sludge until it contacts the bottom hard rock part. After the sludge in this part is sucked out, the propeller 6 is used to move and adjust to the next position to suck out the sludge again, avoiding the need to adjust the position by moving the hull 1, thereby effectively improving the cleaning efficiency of the bottom sludge.

[0048] Example 2

[0049] As attached Figure 2 and Figure 3 As shown: Based on the first embodiment, the hull 1 of the integrated mobile landscape water pollution treatment device of the present invention is further provided with a chute 20, in which a slidable placement frame 21 is provided, which can slide across the moon pool 10; an installation groove 22 is provided below the first buoy 3, which corresponds to the placement frame 21; the chute 20 is used to place the placement frame 21 and restrict its sliding direction and distance; the placement frame 21 is normally located in the chute 20 on the hull 1, at which time the first buoy 3 and the cutter suction assembly 4 can be normally released or pulled up; after the first buoy 3 and the cutter suction assembly 4 are pulled up above the placement frame 21, the placement frame 21 can be slid across the moon pool 10; by manually adjusting the position of the first buoy 3 so that the installation groove 22 below it corresponds to the placement frame 21, and then releasing the lock 15, the first buoy 3 and the cutter suction assembly 4 can be recovered.

[0050] As attached Figure 3As shown, in this embodiment, a second pontoon 23 is placed on the placement frame 21. An ultrasonic mapping instrument 24 is located below the second pontoon 23, and a second locking ring 25 is fixed above the second pontoon 23. The second pontoon 23 is used to install the ultrasonic mapping instrument 24 and can be quickly connected to the traction rope 14 through the second locking ring 25, thereby being released into the water. The second pontoon 23 allows the ultrasonic mapping instrument 24 to face downwards. The ultrasonic mapping instrument 24 emits high-frequency ultrasonic pulses to the bottom of the water and receives the reflected echoes. Combined with precise time difference calculation and depth measurement, it can detect the topographic undulations, sludge thickness, and obstacle distribution at different locations on the bottom of the water in real time and with high precision, thereby generating a complete and clear 3D bottom topographic map. This topographic map can intuitively present the real shape of the bottom of the water and the sludge accumulation, providing accurate data support for subsequent dredging operations, helping to determine the dredging range, plan the cleaning route, and identify key cleaning areas, greatly improving the efficiency, accuracy, and targeting of sludge cleaning.

[0051] As attached Figure 2 As shown, in this embodiment, the hull 1 is provided with a cylinder 26, which is horizontally placed on the side of the slide 20. Its piston rod is fixedly connected to the placement frame 21. The cylinder 26 is used to push out the placement frame 21 and can limit the placement frame 21 when it slides across the moon pool 10, thereby improving its stability.

[0052] Example 3

[0053] The cleaning assembly includes a transmission device and a swing cylinder hinged to the front end of the hull 1. The transmission device includes a frame, a drive roller, and a synchronous belt. The drive roller is rotatably supported on the frame, and the synchronous belt is driven by the drive roller. The frame is hinged to the swing cylinder. A collection bracket is also fixedly connected to the frame of the transmission device. A motor is fixedly connected to the collection bracket, and a collection roller is rotatably connected to it. The motor drives the collection roller, which is located in front of the frame. A collection rake is installed on at least one side of the hull 1. A pressing device is also installed on the hull 1 below the stern end of the transmission device. A cutting device is also fixedly connected to the frame of the transmission device. The cutting device is located behind the collection roller and includes blades and a motor. The motor drives the blades to move relative to each other, cutting the aquatic plants for collection.

[0054] The collecting rake includes a base, a main arm, and a first hydraulic cylinder. One end of the main arm is hinged to the base, one end of the first hydraulic cylinder is hinged to the base, and the other end is hinged to the arm body of the main arm. It also includes an intermediate arm, a rake arm, a rake, a second hydraulic cylinder, and a third hydraulic cylinder. One end of the second hydraulic cylinder is hinged to the arm body of the main arm, and the other end is hinged to one end of the intermediate arm. The arm body of the intermediate arm is hinged to the other end of the main arm. One end of the third hydraulic cylinder is hinged to the arm body of the intermediate arm, and the other end is hinged to one end of the rake arm. The arm body of the rake arm is hinged to the other end of the intermediate arm. The front end of the rake arm is rotatably connected to the rake. A motor is mounted on the rake arm, and the output shaft of the motor is connected to a drive gear. The drive gear meshes with a driven gear, and the driven gear drives the rake. When the rake rotates to the point where the arrangement direction of each rake claw is the same as or approximately the same as the extension and retraction direction of the rake arm, sweeping can begin. This "sweeping" method uses the base connected to the hull 1 as its axis, with the length of the rake arm as its radius, to "sweep" within a certain range, bringing all floating debris on one side of the hull 1 to the bow, thus improving work efficiency. Because the sections of the rake arm can rotate flexibly, its length can be adjusted, meaning the sweeping radius can also be varied, ensuring that the area within the maximum arm length range is cleaned. The base is mounted on a slewing bearing via a flange. The slewing bearing is mounted on a slewing bearing seat fixed to the hull. The slewing bearing is driven by gears on the output shaft of a slewing bearing reducer mounted on the hull 1, which in turn drives the rake to rotate. This allows the rake to rotate around the hull 1 as a fulcrum, expanding the working area and enabling the collection of garbage from the shore.

[0055] The pressing device includes a motor, a left support, a right support, a drive roller, and a driven roller. The two ends of the drive roller are respectively supported on drive bearings within drive bearing seats, and the two ends of the driven roller are respectively supported on driven bearings within driven bearing seats. The drive roller is driven by the motor, and the drive roller and driven roller are arranged side-by-side. The drive bearing seats are fixedly installed on the left and right supports, respectively. The left and right supports are respectively provided with a left mounting groove and a right mounting groove, and two driven bearing seats are movably installed within the left and right mounting grooves, respectively. A left hydraulic cylinder is connected to the support frame, and the piston rod of the left hydraulic cylinder abuts against a left compression spring. The other end of the left compression spring abuts against a driven bearing seat. A right hydraulic cylinder is connected to the right support frame, and the piston rod of the right hydraulic cylinder abuts against a right compression spring. The other end of the right compression spring abuts against another driven bearing seat. Both the driving roller and the driven roller are equipped with several hobbing teeth. By squeezing out the water from the floating objects and aquatic plants, not only is the weight reduced, but the volume of the floating objects and aquatic plants is also reduced, allowing the cleaning boat to carry more surface garbage at once, greatly improving work efficiency.

[0056] This application allows the cutting device on the hull 1 to be removed and a collection arm to be installed, which can be used to collect aquatic plants and garbage in the water. The collection arm can also be fixedly connected to both sides of the transmission device.

[0057] The collecting arm includes a filter screen, a swing arm frame, and a roller shaft. The filter screen is connected to or integrally formed with the swing arm frame. One end of the swing arm frame has a swing arm hinge seat, and the other end of the swing arm frame is respectively provided with a first bearing seat and a second bearing seat. The two ends of the roller shaft are respectively supported on the first bearing seat and the second bearing seat. At least one set of hobbing teeth is provided on the shaft body of the roller shaft. One end of the roller shaft is connected to a drive motor, which is fixedly connected to the first bearing seat or the second bearing seat. When in use, a collecting arm is installed on each side of the bow of the cleaning vessel. The swing arm hinge seat is connected to the hull. The hydraulic cylinder on the hull is connected to the hydraulic cylinder connecting seat. The hydraulic cylinder drives the collecting arm to move circumferentially around the swing arm hinge seat as the rotation axis, and the drive motor drives the roller shaft to rotate.
