Description

Technical Field

[0001] The invention relates to a technology for regulating a river with a lot of sediment, and in particular to a semi-submersible mobile river flow control and guidance vessel. Background Art

[0002] River control projects are river regulation projects designed to control the mainstream and stabilize river flow. They are the most commonly used technical means of controlling river flow, particularly sediment-rich rivers like the Yellow River. Currently, these projects primarily rely on hydraulic structures such as dams, revetments, and spur dikes built along the riverbanks. By directing and constraining water flow, these structures adjust the flow direction, thereby adjusting the river channel and achieving stable river flow control. Practice has shown that these projects have mitigated the adverse effects of fluctuating river flow to a certain extent. However, existing structures such as dams and revetments are generally fixed in position and often become dislocated due to fluctuating river flow. This makes them difficult to adapt to complex and changing river flow patterns and effectively perform their control functions, resulting in a waste of resources. Furthermore, the construction and maintenance costs of existing traditional control projects are high. Therefore, it is imperative to develop new control project structures that can adapt to complex and changing river flow patterns, significantly improve their utilization rate, and reduce construction and maintenance costs.

[0003] In recent years, the development of inland waterway navigation has attracted considerable attention. The continuous accumulation of sediment in sediment-laden rivers has led to shallower water depths and narrower widths, severely impacting their stability and navigability, and becoming a key constraint hindering their restoration. Existing waterway dredging typically involves dredging with dredgers. While effective, this method is costly and significantly disturbs the riverbed, potentially impacting channel stability. Therefore, the development of convenient and efficient silt flushing equipment is crucial to ensuring navigation on sediment-laden rivers.

[0004] In summary, how to develop a movable control engineering structure that can adapt to the complex and changeable river flow and deal with river scouring and siltation is crucial for river flow control and restoration of navigation in sediment-laden rivers. Summary of the Invention

[0005] In view of this, the present invention proposes a semi-submersible movable river flow control and guidance vessel, which can adapt to complex and changeable rivers, maximize its control and guidance role, improve utilization rate, and also can flush and silt the river channel.

[0006] To achieve the above object, the present invention adopts the following technical solutions: The semi-submersible mobile river flow control and navigation vessel of the present invention comprises a hull consisting of a bow, a hull, and a stern, and a navigation drive system provided on the hull. It also comprises a hull fixing mechanism, a high-pressure jet system for adjusting the hull's posture, and a control system. The hull comprises a top plate and a bottom plate. At least two hull fixing mechanisms are provided at each end of the hull, and each hull fixing mechanism includes a protective tube vertically arranged in the hull, a rigid fixing pile and a lifting power source for driving the rigid fixing pile to rise and fall. The top opening of the protective tube is sealed and fixedly connected to the top plate to form a sealing end, and the bottom opening of the protective tube is sealed and fixedly connected to the bottom plate. The bottom plate has a through hole corresponding to the bottom opening, so that the rigid fixing pile passes through the through hole downwardly out of the hull; the control input end of the lifting power source is connected to the control output end of the control system, and the control input end of the high-pressure jet system is connected to the control output end of the control system.

[0007] The beneficial effects are as follows: the navigation drive system of the present invention provides the hull with navigational power in the river, utilizing rigid fixing piles at the front and rear ends of the hull to secure the hull, and utilizing a high-pressure jet system to adjust the hull's posture. It also provides power for inserting and removing the fixing piles, reducing the difficulty of hull transfer and paving the way for the free adjustment of the hull's position. Compared with existing hydraulic structure control and guidance structures, the semi-submersible mobile river flow control and guidance vessel of the present invention can move within the river, and its position can be adjusted according to the complex and changing river flow, fully utilizing its control and guidance functions, improving utilization, and thereby reducing the cost of river management in sediment-rich river sections.

[0008] In a preferred embodiment of the present invention, the lifting power source includes a drive motor disposed within the hull and a rack and pinion pair drivingly connected to the drive motor. The rack and pinion pair comprises a gear fixedly attached to the motor shaft of the drive motor and a rack vertically disposed on the rigid fixing pile, with the gear and rack meshing with each other. This advantageously allows the drive motor to raise and lower the rack via the rack and pinion pair, thereby securing and unlocking the hull and enabling flexible transfer of the hull.

[0009] In a preferred embodiment of the present invention, the high-pressure jet system includes an air compressor, a submersible pump, a high-pressure water gun on the side of the hull, a high-pressure water gun on the bottom of the hull, a high-pressure water gun on the bow and a high-pressure water gun on the stern. The high-pressure water gun on the side of the hull, the high-pressure water gun on the bottom of the hull, the high-pressure water gun on the bow and the high-pressure water gun on the stern are two or more. The air compressor is connected to the air inlets of the high-pressure water gun on the side of the hull, the high-pressure water gun on the bottom of the hull, the high-pressure water gun on the bow and the high-pressure water gun on the stern through an air path. The submersible pump is connected to the water inlets of the high-pressure water gun on the side of the hull, the high-pressure water gun on the bottom of the hull, the high-pressure water gun on the bow and the high-pressure water gun on the stern; the control input ends of the air compressor and the submersible pump are connected to the control output end of the control system.

[0010] The beneficial effect is that the present invention often requires attitude adjustment before sailing or being used as a control guide. The high-pressure jets ejected by the high-pressure water guns around the hull (excluding the high-pressure water guns at the bottom of the hull) form an uneven flow field around the hull, promoting the movement of the hull and thus achieving attitude adjustment; in addition, the reaction force generated by the high-pressure jets assists in adjusting the hull's attitude, further reducing the difficulty of adjusting the hull's attitude.

[0011] The high-pressure water guns at the bottom of the hull in this invention have the following functions: First, the high-pressure jets ejected by the guns directly impact the mudbed, eliminating the suction force exerted by the mud on the bottom of the ship, thereby reducing the initial force of the hull's ascent, facilitating the ship's ascent and assisting in its movement. Second, during actual installation, the guns are mounted near the rigid piles. During the fixing process, the high-pressure jets impact and form holes in the mudbed, thereby reducing the piles' resistance to entering the mud. When extraction is required, the guns at the bottom of the hull spray the surface of the piles and the mudbed, further reducing the piles' resistance to extraction.

[0012] The high-pressure water gun in the present invention can also level the mud bed surface through high-pressure jets, ensuring the flatness of the mud bed surface, thereby making the bottom plate of the hull fully contact with the mud bed surface, ensuring the stability of the hull, and playing a controlling and guiding role; the high-speed jets ejected by the high-pressure water gun can also impact silt and sand, thereby achieving rapid dredging of the river channel.

[0013] In a preferred embodiment of the present invention, the hull further comprises a horizontal partition arranged horizontally between the top plate and the bottom plate; the hull comprises at least one first vertical partition and a plurality of second vertical partitions, the first vertical partition being arranged along the length direction of the hull, the second vertical partition being perpendicular to the first vertical partition, the horizontal partition, the first vertical partition and the second vertical partition dividing the hull into a plurality of independent ballast water tanks, and each of the ballast water tanks is provided with a submersible pump.

[0014] In a more preferred embodiment of the present invention, the high-pressure jet system further comprises a plurality of first brackets for fixing the side high-pressure water guns, the bow high-pressure water guns, and the stern high-pressure water guns, and a second bracket for fixing the bottom high-pressure water guns; The first bracket is arranged on the horizontal bulkhead, and includes a first support member and a first fixed platform arranged vertically, the first support member and the first fixed platform are connected by a first universal joint, and the gun heads of the side high-pressure water gun, the bow high-pressure water gun, and the stern high-pressure water gun are extended outward from the outer shell of the hull; The second bracket includes a second support member and a second fixed platform horizontally arranged on the second vertical partition or the outer shell corresponding to the hull. The second support member and the second fixed platform are connected by a second universal joint, and the gun head of the high-pressure water gun at the bottom of the hull passes downward from the bottom plate.

[0015] In a preferred embodiment of the present invention, the high-pressure jet system further comprises multiple rectifiers. The water inlet of each rectifier is connected to the water supply pipeline of at least two submersible pumps, and the multiple drainage holes of the rectifiers are connected to the water inlets of the side high-pressure water guns, the bottom high-pressure water guns, the bow high-pressure water guns, and / or the stern high-pressure water guns via diverter pipelines. During actual installation, the principle of proximity can be utilized to install high-pressure water guns at different locations together with nearby rectifiers.

[0016] In a preferred embodiment of the present invention, the upper chamber of the bow and each of the ballast water tanks are equipped with multiple electrically controlled water valves, each of which has a control input connected to a control output of the control system. During operation, the on-off state of each of the electrically controlled water valves can be controlled to regulate the amount of water in the ballast water tanks, thereby adjusting the draft of the ship and satisfying the water spraying requirements of the high-pressure water gun.

[0017] In a preferred embodiment of the present invention, the navigation drive system includes a power unit, a propeller, a towing hook, and a boat operating system. The boat operating system is communicatively connected to the power unit. The power unit is mounted at the lower portion of the stern and is in driving connection with the propeller located outside the hull. The towing hook is mounted on the centerline of the bow. In actual installation, the power unit utilizes a diesel engine to power the propeller.

[0018] In a more preferred embodiment of the present invention, the height difference between the towing hook and the bottom plate is greater than or equal to 70% of the ship's height. During actual operation, the towing hook can be connected to a winch on the riverbank or a tugboat in the river, utilizing external power such as the winch or tugboat to assist in the movement of the present invention, thereby achieving flexible position adjustment.

[0019] In a more preferred embodiment of the present invention, the outer shell of the hull is a cement concrete structure (with a steel mesh inside to improve the structural strength of the outer shell), with a thickness greater than or equal to 20 cm, and its bow is an arc structure.

[0020] Compared to existing technologies, the navigation drive system of the present invention provides propulsion for the vessel's navigation in the river. Rigid anchors at the front and rear ends of the vessel secure the vessel, while a high-pressure jet system adjusts the vessel's posture. This system also provides power for inserting and removing the anchors, reducing the difficulty of transferring the vessel and paving the way for flexible adjustment of the vessel's position. Compared to existing hydraulic control structures, the semi-submersible, mobile river flow control vessel of the present invention can be moved within the river, its position adjusted to the complex and ever-changing river flow, fully utilizing its control and guidance capabilities, improving utilization, and ultimately reducing the cost of river management in sediment-rich river sections.

[0028] The following describes an embodiment of the present invention in detail with reference to the accompanying drawings. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process. However, the protection scope of the present invention is not limited to the following embodiment.

[0029] It should be noted that, in the description of the present invention, relational terms such as "first" and "second" are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0030] In the description of the present invention, unless otherwise specified or limited, the terms "connected" and "connection" that may appear should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0031] like Figure 1-7 As shown, the semi-submersible mobile river flow control and navigation vessel of the present invention includes a hull consisting of a bow F1, a hull F2 and a stern F3, a navigation drive system provided on the hull, a hull fixing mechanism 200, a high-pressure jet system for adjusting the hull posture, and a control system for controlling the high-pressure jet system; The hull includes an outer shell and a top plate 101 and a bottom plate 102 disposed within the outer shell. The outer shell is cast using cement concrete (with steel mesh embedded in the concrete during casting) and is 20 cm thick to ensure structural strength. A horizontal partition 103 is also provided within the hull, dividing the interior space of the hull into two equal layers (of course, the heights can be different). The outer shell corresponding to the bow F1 is designed to have an arc-shaped structure. Two hull fixing mechanisms 200 are installed at each end of the hull F2. The hull fixing mechanisms 200 include a protective tube 201 vertically arranged in the hull F2, a rigid fixing pile 202 (a cylindrical pile with a concrete structure, whose bottom can be designed into a conical structure for easy insertion into the mud bed) and a lifting power source for driving the rigid fixing pile 202 to rise and fall. The top of the protective tube 201 is sealed and fixedly connected to the top plate 101 to form a sealed end, and the bottom of the protective tube 201 is sealed and fixedly connected to the bottom plate 102. The bottom plate 102 has a through hole corresponding to the bottom hole, so that the rigid fixing pile 202 passes through the through hole downward to exit the hull F2; the outer wall of the middle part of the protective tube 201 is fixedly connected to the horizontal partition 103; since the protective tube 201 is sealed and connected to the hull, it can not only ensure the free lifting and lowering of the rigid fixing pile 202, but also ensure the sealing performance of the hull to avoid water leakage. In actual use, the lifting power source can drive the rigid fixing piles 202 to descend and ascend. After the hull posture is adjusted to the right position, the rigid fixing piles 202 can be inserted into the mud bed. When the water depth exceeds the height of the hull, the four rigid fixing piles 202 are used to fix the hull. The control input end of each lifting power source and the control input end of the high-pressure jet system are connected to the control output end of the control system. The control system is used to control the automatic rise and fall of each rigid fixed pile 202 and the jet conditions of the high-pressure jet system, thereby realizing the adjustment of the hull posture.

[0032] The navigation drive system of the present invention provides propulsion for the vessel's navigation in the river. Rigid anchors 202 at the front and rear ends of the vessel secure the vessel, while a high-pressure jet system adjusts the vessel's position. This system also provides power for inserting and removing the anchors, reducing the difficulty of moving the vessel and paving the way for flexible adjustment of the vessel's position. Compared to existing hydraulic control structures, the semi-submersible, mobile river flow control vessel of the present invention can be moved within the river, its position adjusted to the complex and ever-changing river flow, fully utilizing its control and guidance capabilities, improving utilization, and ultimately reducing the cost of river management in sediment-rich river sections.

[0033] Combine Figure 4-5It can be seen that the lifting power source is preferably installed in the driving motor 203 in the hull F2 (the driving motor 203 is located in the ballast water tank 106, sealed with a sealed shell, and cooled by river water) and the gear rack pair connected to the driving motor 203. The gear rack pair includes a gear 204 fixed to the motor shaft of the driving motor 203 and a rack 205 vertically arranged on the rigid fixing pile 202. The teeth on the gear 204 are a spiral structure, which meshes with the rack 205. Figure 5 During operation, the driving motor 203 is started to drive the gear 204 to rotate synchronously, and the gear 204 transmits power to the rack 205. The rack 205 is driven by the force to drive the rigid fixing pile 202 to rise or fall. The direction of the rigid fixing pile 202 is changed by changing the rotation direction of the driving motor 203.

[0034] During actual installation, the number of lifting power sources for each hull fixing mechanism 200 can be one group (the power must meet the requirements of inserting and removing the rigid fixing pile 202), and each rigid fixing pile can also be equipped with two or more groups of lifting power sources to ensure that the rigid fixing pile is subjected to balanced force during the lifting process.

[0035] Combine Figure 1-2 As can be seen, hull F2 is equipped with first and second vertical bulkheads 104, 105 (six of which are shown in the figure). The first vertical bulkheads 104 run the length of hull F2, while the second vertical bulkheads 105 are perpendicular to the first vertical bulkheads 104. The horizontal bulkheads 103, first and second vertical bulkheads 104, 105 divide hull F2 into five groups of ballast tanks 106 (each group includes four ballast tanks 106, one above the other and four fore and aft). Each ballast tank 106 is equipped with a submersible pump 302. Furthermore, the second vertical bulkheads 105 on both sides separate the bow F1 and stern F3 from the hull F2, and the horizontal bulkheads 103 divide the bow F1 and stern F3 into two layers, one above the other.

[0036] During actual manufacturing, the present invention designs multiple manholes on the horizontal partition 103 and the top plate 101 to ensure that personnel can freely enter each ballast water tank 106 and the bow F1 and stern F3 for easy maintenance; each manhole is equipped with a sealing cover to ensure sealing performance.

[0037] During actual installation, four hull fixing mechanisms 200 are installed in the lower ballast tanks 106 at both ends of the hull F2. Figure 1-2It can be seen that the high-pressure jet system includes an air compressor 301, a submersible pump 302, a hull side high-pressure water gun 303, a hull bottom high-pressure water gun 304, a bow high-pressure water gun 305 and a stern high-pressure water gun 306. The hull side high-pressure water guns 303 are located on both sides of the hull F2, three on each side, and are installed in the upper ballast water tank 106; there are four hull bottom high-pressure water guns 304, which are installed in the lower ballast water tank 106 close to the hull fixing mechanism 200 (one hull bottom high-pressure water gun 304 is installed in each tank); there are two bow high-pressure water guns 305 and they are installed symmetrically, and there are two stern high-pressure water guns 306. An air compressor 301 (one or two) is installed in the lower chamber of the bow F1 and is connected to the air inlets of the hull side high-pressure water gun 303, the hull bottom high-pressure water gun 304, the bow high-pressure water gun 305, and the stern high-pressure water gun 306 through air paths, providing compressed air to the high-pressure water guns to ensure the jet flow rate of the high-pressure water guns; Each ballast water tank 106 has a submersible pump 302, which supplies water to the high-pressure water guns 303 on the side of the hull, 304 on the bottom of the hull, 305 on the bow and 306 on the stern. Figure 1 The diagram shows that the ballast water tanks are divided into five groups from left to right. The high-pressure water guns are connected to the submersible pumps 302 in the ballast water tanks 106 according to the principle of proximity. For example, if the four submersible pumps 302 near the stern are connected in parallel, a rectifier 307 is connected to their main water supply port. The rectifier 307 has multiple drainage holes, which can be connected one by one to the stern high-pressure water guns 306 via spray pipes (each drainage hole is connected to a high-pressure water gun via a spray pipe). The spray pipes are equipped with electronically controlled valves, and the control system controls the jet flow of each high-pressure water gun by controlling the on and off of the electronically controlled valves. For example, if the four submersible pumps 302 in the second group of ballast water tanks from left to right are connected in parallel, the rectifier 307 at the main water supply port is connected to the two hull side high-pressure water guns 303 and the hull bottom high-pressure water guns 304 corresponding to the rectifier 307. Similarly, the present invention adopts the principle of proximity to connect the high-pressure water guns and submersible pumps 302. The submersible pumps 302 are grouped into four. When a failure occurs to an individual submersible pump 302 in the group, the spraying of the corresponding multiple high-pressure water guns can still be guaranteed.

[0038] Of course, the water guns can also be grouped according to their positions, such as dividing the bow high-pressure water guns 305 into one group, the stern high-pressure water guns 306 into one group, dividing the hull side high-pressure water guns 303 into two groups, and dividing the bow F1 bottom high-pressure water guns into two groups, and placing five groups of high-pressure water guns and five groups of submersible pumps 302 nearby.

[0039] During the actual installation, you can also put the submersible pumps (upper and lower corresponding) in groups of two (see Figure 3), or in groups of three. Of course, they can also be connected in parallel as needed, such as a mixed combination of two submersible pumps in a group, three in a group, or four in a group, ensuring that there are at least two submersible pumps in each group to avoid affecting high-pressure injection due to failure of one of them.

[0040] In actual construction, each ballast water tank 106, the upper chamber of the bow F1 and the upper chamber of the stern F3 are provided with a water inlet with an electric water valve 308. Figure 6 ), each ballast water tank is installed with one (or two or more) water inlets. When the electric water inlet valve 308 is opened, the river enters the ballast water tank 106 or the bow F1 and stern F3, achieving sinking and semi-submerged fixation, and adjusting the draft depth. The water in the ballast water tank 106 can also provide water for the high-pressure water gun.

[0041] During actual installation, the high-pressure jet system further includes a plurality of first brackets 309 and second brackets 310 for fixing the high-pressure water guns 304 on the bottom of the hull in a one-to-one correspondence; Figure 3 As can be seen, the second bracket 310 is installed in the ballast water tank 106 on the lower layer. It includes a second support member 310a and a second fixed platform 310b on the second vertical bulkhead 105 (of course, it can also be the outer shell). The second support member 310a and the second fixed platform 310b are connected by a second universal joint 310c. The high-pressure water gun 304 at the bottom of the hull is fixedly connected to the second fixed platform 310b. The gun head of the high-pressure water gun 304 at the bottom of the hull extends downward from the bottom plate 102, and the gun head and the bottom plate 102 are sealed. A first bracket 309 is provided in the ballast water tank 106, the upper chamber of the bow F1 and the upper chamber of the stern F3 corresponding to the hull side high-pressure water gun 303 to meet the fixed installation requirements of the hull side high-pressure water gun 303, the bow high-pressure water gun 305 and the stern high-pressure water gun 306; the first bracket 309 is set on the horizontal partition 103, and it includes a vertically arranged first support member 309a and a first fixed platform 309b. The first support member 309a and the first fixed platform 309b are connected by a first universal joint 309c. The gun heads of the hull side high-pressure water gun 303, the bow high-pressure water gun 305 and the stern high-pressure water gun 306 pass horizontally outward from the outer shell of the hull (or pass obliquely downward), and can spray around the hull, circling the nearby water flow and providing a jet reaction force to adjust the hull posture.

[0042] During actual installation, the first support member and the second support member both adopt a telescopic structure, such as a gas spring telescopic rod or a hydraulic rod with freely adjustable height, so that the support member and the high-pressure water gun form a connecting rod structure; a perforation (with a diameter larger than the diameter of the gun head) is opened on the hull corresponding to the gun head of each high-pressure water gun, and a rubber pad is installed at the perforation to ensure a sealed connection between the gun head and the perforation (that is, a soft connection between the gun head and the perforation), providing a certain amount of movement space for the gun head on the basis of ensuring sealing, thereby ensuring the free adjustment requirements of the gun head of the high-pressure water gun.

[0043] The present invention often requires attitude adjustment before sailing or serving as a control guide. The high-pressure jets ejected by the high-pressure water guns around the hull (excluding the high-pressure water gun 304 at the bottom of the hull) form an uneven flow field around the hull, promoting the movement of the hull and thus achieving attitude adjustment; in addition, the reaction force generated by the high-pressure jets assists in adjusting the hull's attitude, further reducing the difficulty of adjusting the hull's attitude.

[0044] The high-pressure water guns on the bottom of the hull in this invention have the following functions: First, the high-pressure jets ejected by the guns directly impact the mudbed, eliminating the suction force exerted by the mud on the bottom of the ship, thereby reducing the initial force of the hull's ascent, assisting in the ship's initial ascent, and facilitating its movement. Second, during actual installation, the guns 304 are installed near the rigid piles. During the fixing process, the high-pressure jets impact the mudbed, creating holes, thereby reducing the resistance of the rigid piles 202 to entering the mud. When extraction is required, the guns 304 can spray the mudbed, reducing the resistance of the rigid piles 202 to extraction.

[0045] The high-pressure water gun in the present invention can also level the mud bed surface through high-pressure jets to ensure the flatness of the mud bed surface, thereby making the bottom plate 102 of the hull fully contact with the mud bed surface, ensuring the stability of the hull, and playing a controlling and guiding role; the high-speed jet ejected by the high-pressure water gun can also impact silt and sand, thereby achieving rapid dredging of the river channel.

[0046] Combine Figure 1-2 As can be seen, the navigation drive system includes a power unit 501, a propeller 502, a towing hook 503, and a ship operation system. The ship operation system is in communication with the power unit 501. The power unit 501 is installed in the lower chamber of the stern F3 and is in transmission connection with the propeller 502 located outside the hull. The propeller 502 is located on the centerline L2 of the hull, and the distance between the propeller 502 and the hull is controlled to be approximately 1.5m. The towing hook 503 is installed on the center line of the bow F1. The height difference between the towing hook 503 and the bottom plate 102 of the hull is controlled to be more than 70% of the hull height. For example, when the hull height is 4m, the height difference between the towing hook 503 and the bottom plate 102 of the hull can be 3m, or 3.2m, etc. The towing hook 503 is convenient for the towing rope to pass through, and can assist the movement of the hull with the help of external power such as a winch on the river bank or a tugboat in the river. It is particularly suitable for the movement and adjustment of the hull in shallow water conditions to meet actual needs.

[0047] During actual installation, the control system and the ship's operating system of the present invention are integrated and installed in the lower chamber of the bow F1. The submersible pump 302, the electric water valve 308, the electric control valve, and the air compressor 301 are all connected to the control input of the control system. The control system can be used to control their startup and shutdown, thereby improving the degree of automated control of the hull. It should be noted that the controller of the present invention can be a PLC controller, which controls the startup and shutdown of the above-mentioned components. Of course, the controller of the present invention can also be an industrial computer with important computer properties and characteristics, and can also be equipped with a wireless communication module to achieve connection with a remote terminal, receive control instructions from the remote terminal, and feedback relevant parameters of the real-time working status.

[0048] In actual construction, the length, depth, and height of the hull can be determined according to design requirements, for example, length × width × height = 50m × 12m × 4m. When the hull height is equal to or slightly greater than the water depth at the control position, the hull is fixed by adjusting the draft. Specifically, water is pumped into each ballast tank 106 to gradually increase the hull draft until the hull bottom plate 102 is fully in contact with the mud bed. During this process, high-pressure water jets 304 under the hull can be used to adjust the mud bed surface, ensuring that the hull bottom plate 102 and the mud bed are in as complete contact as possible. When relocation is required, water in the ballast tanks 106 is released to reduce the hull draft. The direction of the bow F1 is adjusted using high-pressure water jets on the sides of the hull F2 and the navigation drive system. The high-pressure jets generated by the high-pressure water jets generate disturbances, which, combined with the reaction force generated by the high-pressure water jets, provide power for adjusting the direction of the bow F1. If the hull is stranded, tugboats or winches on the riverbank can assist in its movement.

[0049] When the hull height is less than the water depth at the required control position (i.e., when the water depth is greater than 4 meters), the hull is secured using rigid fixing piles 202. Specifically, after the hull is adjusted into position, high-pressure water guns 304 on the hull's underside spray water onto the mud bed, creating holes in the mud bed. Rigid fixing piles 202 are then lowered and inserted into the mud bed. The four rigid fixing piles 202 secure the hull to ensure its control function. When the hull needs to be moved, the mud bed is sprayed with high-pressure water guns 304 on the hull's underside to reduce the resistance to pulling out the rigid fixing piles 202.

[0050] Finally, it should be emphasized that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments without inventive effort, or replace some of the technical features therein with equivalents. Therefore, any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
