Description

Technical Field

[0001] This utility model relates to the field of assembled boats, specifically a water-jet propulsion magnesium-aluminum alloy assembled boat. Background Technology

[0002] Magnesium-aluminum alloys have a relatively low density, making boats lighter and easier to transport, maneuver, and dock. At the same time, they possess high strength, capable of withstanding certain external forces and water pressure, ensuring the structural stability of the boat. Magnesium-aluminum alloys also have excellent oxidation and corrosion resistance, making them resistant to rust and corrosion even under prolonged contact with water and humid environments, extending the boat's service life. They can be assembled using various methods such as welding and bolting, making the manufacturing process relatively simple. This allows for the production of boats of various shapes and sizes to meet diverse application scenarios. When a part of the boat is damaged, it can be easily disassembled for replacement or repair, eliminating the need for extensive repairs to the entire boat and reducing maintenance costs and time.

[0003] Chinese Patent No. CN202220470215.X discloses a new energy waterjet propulsion boat hybrid power device, including a waterjet propulsion unit, a drive motor, a motor driver, a fuel engine, a connecting clutch, a power battery pack, and a hull. The output shaft of the fuel engine is fixedly connected to the fuel engine clutch end shaft. One end of the drive motor is fixedly connected to a coupling, and the other end of the drive motor is fixedly connected to the motor clutch end shaft. The waterjet propulsion unit, drive motor, motor driver, fuel engine, connecting clutch, and power battery pack are respectively installed inside the hull. A control console is fixedly connected to the platform of the hull. The two ends of the motor driver are electrically connected to the motor end cable and the battery pack end cable, respectively.

[0004] As can be seen from the above, using both electricity and fuel to propel a boat improves its power and maneuverability. The boat does not need to be equipped with an additional generator, which also reduces manufacturing costs. However, this project also has the following shortcomings: the water intake channel lacks an efficient filtration structure, and impurities in the water, such as weeds, gravel, and floating objects, can easily enter the propulsion system with the water flow, causing impeller wear or even shutdown, which seriously affects the reliability of navigation.

[0005] Therefore, a waterjet-propelled magnesium-aluminum alloy spliced ​​boat is proposed to address the above problems. Utility Model Content

[0006] To overcome the shortcomings of existing technologies, such as the problem that impurities can easily enter the propulsion system with the water flow, this utility model proposes a water-jet propulsion type magnesium-aluminum alloy spliced ​​boat.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The water-jet propulsion type magnesium-aluminum alloy spliced ​​boat of this utility model includes a main body, and a filter propulsion assembly is provided on one side of the main body. The filter propulsion assembly includes a filter element and a propulsion element. The filter element includes a servo motor, and a spiral auger blade is fixedly installed at the output end of the servo motor. The spiral auger blade is movably installed in the inner cavity of the filter chamber. A water inlet channel is fixedly installed at the bottom of the filter chamber. An arc-shaped filter screen is fixedly installed at the top of the filter chamber, and a water delivery channel is fixedly installed through the arc-shaped filter screen. A chip removal channel is fixedly installed on one side of the bottom of the filter chamber.

[0008] Preferably, the propulsion component includes an engine, the output end of which is fixedly mounted with a drive shaft, one end of which is through which an impeller is fixedly mounted, and the impeller is movably mounted in the inner cavity of the propulsion chamber.

[0009] Preferably, the propulsion component further includes a hydraulic cylinder, one side of which is hinged to the top of the propulsion chamber. A piston rod is movably mounted on the output end of the hydraulic cylinder, and a crank is hinged to one end of the piston rod. A linkage rod is fixedly mounted on one end of the crank. A movable water nozzle is movably mounted through the linkage rod and is hinged to one side of the propulsion chamber.

[0010] Preferably, the main body includes a hull, the bottom of the hull has a connecting groove, and the top of the hull is fixedly installed with a fixing frame.

[0011] Preferably, the hull is fixedly installed with a water inlet channel via a connecting groove, and a servo motor is fixedly installed in the inner cavity of the hull.

[0012] Preferably, a water supply channel is fixedly installed on one side of the bottom of the propulsion compartment, and the engine is fixedly installed in the inner cavity of the hull.

[0013] The advantages of this utility model are:

[0014] 1.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1-5As shown, a water-jet propulsion magnesium-aluminum alloy spliced ​​boat includes a main body 1. A filter propulsion assembly 2 is provided on one side of the main body 1. The filter propulsion assembly 2 includes a filter element 3 and a propulsion element 4. The filter element 3 includes a servo motor 21. A spiral auger blade 24 is fixedly installed at the output end of the servo motor 21. The spiral auger blade 24 is movably installed in the inner cavity of the filter chamber 22. A water inlet channel 26 is fixedly installed at the bottom of the filter chamber 22. An arc-shaped filter screen 23 is fixedly installed at the top of the filter chamber 22, and a water delivery channel 25 is fixedly installed through the arc-shaped filter screen 23. A chip removal channel 27 is fixedly installed on one side of the bottom of the filter chamber 22.

[0025] During operation, as the boat navigates, water flows into the filter chamber 22 through the inlet channel 26. The servo motor 21 drives the auger blades 24 to rotate clockwise. After being filtered by the arc-shaped filter screen 23, the clean water enters the propulsion chamber 34 through the water delivery channel 25. Impurities are intercepted by the arc-shaped filter screen 23, and the auger blades 24 push the impurities along the bottom of the filter chamber 22 to the chip removal channel 27. The chip removal channel 27 can be opened periodically to remove impurities and avoid blockage.

[0026] Furthermore, the propulsion component 4 includes an engine 31, with a drive shaft 32 fixedly mounted at the output end of the engine 31. One end of the drive shaft 32 passes through and is fixedly mounted with an impeller 33, which is movably mounted in the inner cavity of the propulsion chamber 34.

[0027] When in operation, the engine 31 starts and drives the impeller 33 to rotate at high speed through the transmission shaft 32. The impeller 33 forms a negative pressure in the propulsion chamber 34, which draws in clean water from the water delivery channel 25 and accelerates its ejection, generating a backward thrust that propels the boat forward.

[0028] Furthermore, the propulsion component 4 also includes a hydraulic cylinder 35. One side of the hydraulic cylinder 35 is hinged to the top of the propulsion chamber 34. A piston rod 36 is movably mounted on the output end of the hydraulic cylinder 35. A crank 37 is hinged to one end of the piston rod 36. A linkage rod 38 is fixedly mounted on one end of the crank 37. A movable water nozzle 39 is movably mounted through the linkage rod 38. The movable water nozzle 39 is hinged to one side of the propulsion chamber 34.

[0029] During operation, when the boat's course needs to be adjusted, the hydraulic cylinder 35 drives the piston rod 36 to extend or retract. The piston rod 36 drives the crank 37 to rotate, and the crank 37 pushes the movable water nozzle 39 to swing around the hinge point through the linkage rod 38. When the piston rod 36 extends, the movable water nozzle 39 deflects to the left, changing the water spray direction and turning the boat to the right; conversely, when the piston rod 36 retracts, the movable water nozzle 39 deflects to the right, turning the boat to the left, thus achieving precise control.

[0030] Furthermore, the main body 1 includes a hull 11, a connecting groove 12 is provided at the bottom of the hull 11, and a fixing frame 13 is fixedly installed on the top of the hull 11.

[0031] During operation, the hull 11 is made of magnesium-aluminum alloy, which is lightweight and high-strength. The connecting groove 12 can be spliced ​​with other hull modules, making it easy to expand the length or function of the boat according to needs. The fixing frame 13 is used to install the cockpit, cargo or other equipment, improving the practicality of the boat.

[0032] Furthermore, a water inlet channel 26 is fixedly installed on the hull 11 via a connecting groove 12, and a servo motor 21 is fixedly installed in the inner cavity of the hull 11.

[0033] During operation, the water inlet channel 26 is sealed to the connecting groove 12 to ensure smooth water flow into the filter chamber 22. The servo motor 21 is installed inside the hull 11 for easy maintenance and control.

[0034] Furthermore, a water supply channel 25 is fixedly installed on one side of the bottom of the propulsion compartment 34, and the engine 31 is fixedly installed in the inner cavity of the hull 11.

[0035] During operation, the water supply channel 25 delivers filtered water to the propulsion chamber 34, and the engine 31 is located inside the hull 11, driving the impeller 33 through the drive shaft 32.

[0036] Working principle: During navigation, water flows through the inlet channel 26 into the filter chamber 22. The spiral auger blades 24 and the arc-shaped filter screen 23 work together to filter impurities. The clean water enters the propulsion chamber 34 through the water delivery channel 25. The engine 31 drives the impeller 33 to spray water and generate thrust. At the same time, the hydraulic cylinder 35 controls the swing of the movable water spray nozzle 39 to adjust the direction of water spray, so as to realize the forward movement and turning of the boat.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
