Background technique

Surface propeller (semi-submersible propeller) is a kind of propulsion device applied to high-speed speedboats. Generally, propellers are all immersed in water, while surface propellers generally work in oblique flow, and there are blades entering and exiting the water surface, which makes it work There will be extremely violent waves in the middle, which not only wastes part of the energy, but also reduces the stealth of the military speedboat.

The wave plate is a kind of ship appendage used in high-speed speedboats. Its main function is to reduce drag and restrain the bow of the hull, so as to improve the stability of the speedboat under high-speed motion. On a general speedboat, the wave breaker is arranged at the bottom of the boat, and the installation position will interfere with the reflected water flow when the ship is reversed by the surface paddle propulsion, so it cannot be used in conjunction with the surface paddle propeller. Therefore, a corresponding wake pressure device is required to block and recover energy specifically for the splash generated by the surface paddle.

Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Referring to Figures 1 to 6, the components of the high-speed boat stern wave suppressing device combined with surface paddles provided by the present invention include: wave suppressing board 1, stern springboard 2, hydraulic push rod 3, and parallel motor 4.

Wherein, the wave suppressing board 1 is connected to the bottom of the tail springboard 2 through a hinge, and the wave suppressing board 1 can rotate around the hinge. The two ends of the hydraulic push rod 3 are respectively connected to the bottom of the springboard 2 and the wave pressing board 1 in a hinged connection.

This mechanism can be abstracted as a crank-slider mechanism, as shown in Figure 5, where the slider is the active part, and when the slider moves, it drives the crank (wave pressing plate) to swing, thereby changing the angle between the wave pressing plate and the tail springboard .

At low speeds, the included angle between the wave breaker 1 and the tail springboard 2 is the smallest, and the elongation of the hydraulic rod 3 is zero. When the high-speed planing boat is sailing, as the speed continues to increase, the surface paddles will arouse a lot of water splashes, and at the same time, the sailing attitude of the hull will also change, which will cause longitudinal motion instability in severe cases. At this time, it is necessary to activate the tail pressure wave device and call the motor 4. As shown in Figure 4, the motor starts to rotate in the forward direction, so that the hydraulic oil can output pressure oil through the bidirectional gear pump, and send it to the working oil cylinder through the integrated block of the oil circuit to realize The push and pull movement of the piston rod, at this time, the length of the hydraulic push rod 3 is constantly increasing, extending from L1 to L2, and at the same time, the angle between the wave pressing board and the tail springboard becomes larger β, when the angle is suitable, the motor stops working, the length of the push rod is fixed, and the pressure The state of surfboard 1 is fixed.

The invention relates to a wave suppressing device used on a high-speed ship with a surface paddle as a propeller, in particular to a device for improving the stealth and navigation performance of a speedboat by blocking the surface paddle from making waves. Including hydraulic push rod, rotating shaft, wave pressure plate, motor and so on. The wave breaker is installed above the surface paddle, fixed on the tail springboard and extending downward, and the angle between the tail springboard and the tail springboard can be adjusted. The main function of the invention is to intercept the splashing water generated by the surface paddles during operation and the waves generated behind the ship. Its significance mainly includes: improving the stealth performance of the speedboat; sex; convenient reversing. The invention has the advantages of compact structure, low cost and strong maneuverability, and is mainly used for high-speed boats propelled by surface paddles.

The main components of the present invention are a wave pressing plate, a hydraulic push rod, a motor, and a wave pressing plate rotating shaft. According to the different sailing conditions, the angle between the wave breaker and the stern ramp (stern seal) is adjusted through the electro-hydraulic push rod. The hydraulic push rod uses the electric motor as the power source, and through the positive (reverse) rotation of the electric motor, the hydraulic oil will output the pressure oil through the bidirectional gear pump, and then send it to the working oil cylinder through the integrated block of the oil circuit, so as to realize the reciprocating motion of the piston rod, thereby changing the pressure of the push rod. The length of the rod is used to adjust the angle between the wave pressure board and the tail springboard. When the angle reaches the requirement, the motor stops rotating, the oil pressure of the push rod is fixed, and the length of the push rod remains unchanged. At this time, a stable triangular structure is formed between the tail springboard, the push rod and the wave breaker, so as to block the splashing of the surface oars and achieve the purpose of enhancing the concealment of the speedboat, reducing drag at medium and low speeds, and enhancing the stability of motion at high speeds.

The invention is mainly used on high-speed boats with surface paddles as propulsion devices, and is mainly used for intercepting waves generated by the surface paddles at the stern.

The present invention is installed above the surface paddle, and is fixed on the stern springboard of the high-speed boat and extends downward.

The material of the wave breaker of the present invention can be composite materials such as glass fiber reinforced plastics and carbon fibers, and can also be metal materials such as stainless steel and aluminum alloy.

The motor of the present invention can be a 12V DC geared motor or a 24V DC geared motor.
