Technical Field

[0001] This invention provides a generating device, and particularly relates to a two-stage thrust generating device for a vertical air sail. Background Technology

[0002] The core of traditional vertical airsail devices lies in the interaction between the shape and structure of the vertical airsail and the airflow, thereby providing thrust to ships or other carriers, which helps to improve the carrier's navigation efficiency and reduce energy consumption.

[0003] Existing vertical airsail devices typically consist of a main vertical airsail body, possibly equipped with only a simple air intake and thrust output section, lacking efficient multi-stage airflow acceleration and guidance structures. Their thrust generation efficiency is relatively low, making it difficult to meet the demands of high-performance navigation. Utility Model Content

[0004] To address the aforementioned problems, this application provides a two-stage thrust generation device for a vertical airsail, which solves the issues of insufficient thrust and low efficiency in traditional vertical airsails.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a two-stage thrust generation device for a vertical air sail, comprising a vertical air sail, wherein the rear end of the vertical air sail is provided with an air intake pipe connected to the vertical air sail, the air intake pipe being trapezoidal in shape, wider at the top and narrower at the bottom, the connection part with the vertical air sail being a plane, and the upper edge of the air intake pipe being parallel to the lower edge of the vertical air sail.

[0006] The rear end of the intake pipe is provided with a worm gear structure connected to the intake pipe. The worm gear structure is conical in shape, with its large end connected to the intake pipe and its small end extending backward. The axis of the worm gear structure coincides with the axis of the vertical air sail.

[0007] The rear end of the worm gear structure is provided with a thrust generating unit connected to the small end of the worm gear structure. The unit is cylindrical in shape, and the end connected to the small end of the worm gear structure is a plane. The axis of the thrust generating unit coincides with the axis of the vertical air sail.

[0008] Preferably, the conical design of the worm gear structure is used to accelerate the airflow entering the device and guide it to the thrust generation unit, and the turbine structure includes a housing integrally connected to the thrust generation unit.

[0009] Preferably, the interior of the outer shell is provided with a plurality of evenly distributed and circumferentially distributed flow-limiting plates, and the inner side of the flow-limiting plates is provided with turbine plates that are movably embedded inside the outer shell.

[0010] Preferably, the turbine plate comprises several plates that are evenly distributed around the circumference and arranged in a conical spiral pattern.

[0011] Preferably, the cylindrical tube of the thrust generation unit is used to convert the airflow accelerated by the worm gear structure into thrust output. The circular steel structure shell of the outer casing is used to protect the internal components and guide the airflow.

[0012] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0013] This invention achieves two-stage thrust through an intake pipe, a worm gear structure, and a thrust generation unit. A vertical air sail guides the airflow into a trapezoidal intake pipe, where it is initially accelerated. The airflow then enters a conical worm gear structure, where it is further accelerated and guided to the thrust generation unit. The cylindrical tube of the thrust generation unit converts the high-speed airflow into thrust output.

[0014] This device solves the problems of insufficient thrust and low efficiency in traditional single-stage thrust devices. Through multi-stage airflow guidance and acceleration, it improves thrust generation efficiency.

Structurally, the integrated shell design of the worm gear structure and thrust generation unit enhances the overall integrity of the device. The special distribution of the internal flow restrictor and turbine plates improves the precision of airflow control, and the circular steel shell also protects the internal components.

[0021] 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 protection scope of the present utility model.

[0022] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] like Figure 1 and Figure 2 As shown, a two-stage thrust generation device for a vertical airsail includes a vertical airsail with a trapezoidal air intake pipe (wider at the top and narrower at the bottom) connected to its rear end. The connection between the air intake pipe and the vertical airsail is planar, and the upper edge of the air intake pipe is parallel to the lower edge of the vertical airsail. A conical worm gear structure is connected to the rear end of the air intake pipe. The larger end of the worm gear structure connects to the air intake pipe, and the smaller end extends rearward, its axis coinciding with the axis of the vertical airsail. Further rearward, a cylindrical thrust generation unit is connected to the smaller end of the worm gear structure. The end of the thrust generation unit that connects to the smaller end of the worm gear structure is planar, and its axis also coincides with the axis of the vertical airsail.

[0025] In this embodiment, the rear end of the vertical airsail is connected to the trapezoidal air intake pipe, and the upper edge of the air intake pipe is parallel to the lower edge of the vertical airsail to ensure smooth airflow. The rear end of the air intake pipe is connected to a conical worm gear structure, with its large end connected to the air intake pipe and its small end extending and connected to the thrust generation unit. The axes of all components coincide with the axis of the vertical airsail to ensure the consistency and stability of the airflow direction.

[0026] The trapezoidal air inlet increases the inlet area of ​​the airflow, allowing more air to be efficiently guided into the device. Secondly, the conical worm gear structure provides initial acceleration and guidance of the airflow, leveraging its shape to initially increase the airflow velocity. Finally, the thrust generation unit further converts the accelerated airflow into thrust output. Through multi-stage acceleration and guidance, thrust generation efficiency is significantly improved, effectively solving the problems of insufficient thrust and low efficiency in traditional vertical air sail devices. The entire device not only improves airflow utilization efficiency but also enhances the stability and reliability of thrust output.

[0027] like Figure 2 and Figure 3 As shown, in the two-stage thrust generation device of the vertical air sail, the worm gear structure is conical, which accelerates the airflow entering the device and guides it to the thrust generation unit. It includes a shell integrally connected to the thrust generation unit. Inside the shell are evenly distributed, circumferentially arranged flow-limiting plates. Turbine plates are movably embedded inside the flow-limiting plates, and the turbine plates are composed of several circumferentially distributed, conically spirally arranged plates. The cylindrical tube of the thrust generation unit converts the airflow accelerated by the worm gear structure into thrust output. The circular steel structure shell of the outer casing protects the internal components and guides the airflow. In this embodiment,

[0028] In one or more feasible embodiments, in practical applications, the secondary thrust generation device of this vertical airsail will be installed on a ship or other waterborne vessel, requiring integration with existing structures such as the vessel's deck and fixed supports, and securely installed using methods such as bolts and welding. Simultaneously, to ensure the normal operation and maintenance of the device, an existing electrical control system is also required to monitor and control the device's operating status, such as adjusting the air intake and monitoring airflow velocity. Regarding materials, the vertical airsail can be made of high-strength aluminum alloy or carbon fiber composite materials to reduce weight and increase structural strength; the air intake pipe, worm gear structure, and thrust generation unit can be made of corrosion-resistant stainless steel or engineering plastics to adapt to the complex marine environment; the outer shell is preferably made of fiberglass or corrosion-resistant metal materials to ensure its stable and reliable function in protecting internal components and guiding airflow. The application of these existing technical structures and materials (not detailed in the specifications) aims to provide the device with robust support, precise control, and durability to withstand harsh environments, ensuring that the device efficiently and stably leverages its secondary thrust generation advantages in practical use.

[0029] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
