In this application, the high-pressure water flow generating device 2 and the jet direction adjusting device 3 are installed on the ship's side 1 by non-destructively installing the fixture 6; according to different forms of complex flow patterns such as bubbling whirlpools, sliding beam currents, sweeping bend currents, and vortices, the high-pressure water flow generating device 2 provides high-pressure water of different modes for the multi-modal water jet device 4; according to the adverse complex flow patterns affecting the safe navigation of ships, the jet direction adjusting device 3 can adjust the jet direction and angle of the high-pressure water in the multi-modal water jet device 4, that is, adjust the mutual angle of the jet water flow and the impact of the complex water flow, so as to eliminate or weaken the influence of the complex water flow on the ship's navigation direction, and eliminate or reduce the impact and swaying effect of the complex water flow on the ship. Overall, this application can effectively cope with complex flow patterns, eliminate or weaken the adverse effects of complex flow patterns on ship navigation by jetting high-pressure water flows of different modes, and improve the navigation capacity and safety of waterways.

[0057] By means of the horizontal direction adjusting rotating disk 16, the angle between the multi-modal water jet device 4 and the connecting vertical shaft 20 can be adjusted, thereby achieving the purpose of adjusting the water jet direction of the multi-modal water jet device 4.

[0060] The bolts sequentially pass through the corresponding horizontal limit screw holes 18 on the two sets of horizontal direction adjusting rotating disks 16, thereby limiting the angle between the two sets of horizontal direction adjusting rotating disks 16, that is, limiting the water jet direction of the multi-modal water jet device 4; through the above, the water jet direction of the multi-modal water jet device 4 is adjusted or limited through the vertical direction adjusting rotating disk 15 and the horizontal direction adjusting rotating disk 16.

[0061] In a further optimized solution, the high-pressure water flow generating device 2 includes:

The outlet of the pressure vessel is communicated with the multi-modal water jet device 4 through the high-pressure pipeline 5. The high-pressure water pump is connected to the water source through the water inlet pipeline 7; connecting to the water source means placing the water inlet of the water inlet pipeline 7 below the water surface;

Among them, the power system 8 refers to the power supply for the high-pressure water pump, and according to the power source of the ship, an electric motor, a diesel or gasoline engine, etc. can be selected; the high-pressure water pump refers to the device that raises water from a low-pressure state to a high-pressure state. Commonly used high-pressure water pumps include plunger pumps, piston pumps, screw pumps, etc. Usually, a plunger pump is selected.

[0074] For a further optimized solution, the multi-modal water jet device 4 further includes:

[0075] A steering adjustment handle 23, and the steering adjustment handle 23 is fixedly connected to the adjustable jet longitudinal rod 24.

[0084] This application provides a device operation method for an inland waterway ship to resist complex flow patterns, which is applied to the device for an inland waterway ship to resist complex flow patterns as described above, and includes the following steps:

[0085] Step 1: Install at least one set of 360° jet multi-modal water jet side thrust system on the left and right ship's sides 1 of the ship respectively;

[0086] Step 2: Install the high-pressure water flow generating device 2 on the ship's side 1 through the non-destructive installation fixture 6;

[0087] Step 3: Install the jet direction adjusting device 3 on the non-destructive installation fixture 6;

[0088] Step 4: Install the multi-modal water jet device 4 on the jet direction adjusting device 3, and connect the multi-modal water jet device 4 to the high-pressure water flow generating device 2;

[0089] Step 5: Judge the adverse effects of complex flow patterns on the ship. Initially adjust the direction and angle of the jet through the jet direction adjusting device 3, and adjust and control the flow rate and pressure of the high-pressure water flow through the high-pressure water flow generating device 2.

[0090] The specific steps are as follows: 1. For small and medium-sized ships that are expected to sail in complex mountain channels, equip with more than two sets of 360° jet multi-modal water jet side thrust systems. When judging whether the ship is about to enter a river section with complex terrain and frequent complex flow patterns, analyze the necessity of installing the 360° jet multi-modal water jet side thrust system.

[0091] 2. For ships about to enter a river section with complex terrain and frequent complex flow patterns, design a plan to install at least one set of 360° jet multi-modal water jet side thrust systems on the left and right ship sides of the ship according to monitoring data and crew work experience.

[0092] 3. Install the high-pressure water flow generating device 2. Fix the high-pressure water flow generating device composed of the power system 8, high-pressure water pump, pressure vessel, filtration system, high-pressure control valve 10, pressure sensor 11, monitoring system, and safety device 9 on the ship side 1 through the non-destructive installation fixture 6, and install a rubber pad. Then place the water inlet pipe 7 of the high-pressure water flow generating device 2 on both sides of the ship, and tie a heavy object at the end to keep the water inlet always submerged more than 50 cm below the water surface. Among them, the filtration system is installed between the water inlet pipe 7 and the high-pressure water pump to remove impurities in the water, avoid debris in the high-pressure water, and prevent jet blockage; the filtration system is a conventional water filtration structure to filter large particle impurities in the water.

[0093] 4. Install the jet direction adjusting device 3. Fix the jet direction adjusting device composed of the horizontal steering system and the vertical steering system on the ship side 1 through the non-destructive installation fixture 6, and install a rubber pad.

[0094] 5. Install the multi-modal water jet device 4, including a rigid rod-shaped structure, which is fixed on the horizontally adjustable rotating disk 16 through the installation joint 17, and install a nozzle suitable for the ship to resist possible complex flow patterns at the other end.

[0095] 6. Connect the water inlet of the multi-modal water jet device 4 to the water outlet of the high-pressure water flow generating device 2 with a high-pressure pipe 5 and a high-pressure joint.

[0096] 7. Repeat steps 3 to 6 to complete the installation of the designed 360° jet multi-modal water flow thrust system.

[0097] 8. Determine the adverse effects of the complex flow pattern on the ship, and preliminarily adjust the horizontal direction and vertical angle of the jet through the jet direction adjustment device 3.

[0098] 9. The high-pressure water flow generating device 2 is started by connecting to the ship's own electric power system, or starting the gasoline or diesel power system of the high-pressure water flow generating device 2, so that it provides high-pressure water flow for the multi-modal water flow injection device 4.

Observe the navigation conditions of the ship and the interference of complex flow patterns on the ship, timely adjust the jet direction through the jet direction regulating device 3, and adjust and control the flow and pressure of the high-pressure water flow through the high-pressure control valve of the high-pressure water flow generating device 2, so as to ensure the safe navigation of the ship.

[0100] Through the above, this application has the following advantages:

[0101] One of the advantages: the equipment and devices required for the lossless water jet thruster designed in this application can be selected from existing industrial products without the need for separate design and production. For example, high-pressure pumps, accumulators, high-pressure pipelines, etc. used for industrial cleaning and cutting can be directly used in the assembly of this application, and the cost of promotion and application is low.

[0102] Advantage 2: A 360° jet multi-modal water flow thrust system is installed on the side of the ship above the water surface. Compared with methods such as adding stabilizing fins to the hull, creating bubble curtains, etc., which require opening holes in the hull, this application does not damage the hull.

[0103] Advantage three: Compared with adding lateral propellers and thrusters to the underwater hull, installing a 360° jet multi-modal water flow thruster system on the side of the ship above the water surface will not destroy the natural ecology of the shallow riverbed on both sides of the river due to large-scale underwater disturbances, especially in ecologically sensitive areas (such as the sandy riverbed in the middle reaches of the Yangtze River).

[0104] Advantage 4: The installation and use of the 360° jet multi-modal water thruster system is simple and convenient. It can be installed and disassembled at any time according to needs. It is not an essential component for shipbuilding; it is only an optional additional device for small and medium-sized ships sailing in mountainous waterways.

[0105] Advantage 5: The multi-modal water jet device of the 360° multi-modal water jet thruster system can replace the nozzle at any time according to the different forms of complex flow patterns encountered during the ship's navigation, and spray different forms of water flow to eliminate or weaken the adverse effects of complex flow patterns on the ship.

[0106] Sixth Advantage: The 360° jet multi-modal water flow side thrust system can arbitrarily adjust the direction of the jet water flow. For example, it can eject water flow vertically downward. Relying on the reaction force, it can lift the hull and reduce the draft of the hull, which helps to improve the passing ability of the ship in mountain channels. It can also eject water flow in the opposite direction of the ship's sailing direction. Relying on the reaction force, it can accelerate the sailing speed of the ship, etc.
