Description

Technical Field

[0001] This utility model relates to the field of boat technology, and in particular to a power system and an aerodynamic all-terrain vessel using the power system. Background Technology

[0002] Air-powered boats, also known as air-propelled boats, are generally powered by an internal combustion engine that drives a propeller to generate propulsion. They are used in environments where conventional vehicles and boats cannot operate, such as water, snow, ice, deserts, and swamps. These vehicles have wide applications in various fields, including disaster relief, rescue, field operations, exploration, wetland surveys, environmental protection, and tourism.

[0003] In the existing technology, most aerodynamic boats are designed with a power system in which the engine and propeller are connected in a one-to-one transmission. This power system has the following problems: (1) Power and load are contradictory: The engine is set in the power system to drive the propeller to rotate and provide power for the aerodynamic boat to move. However, the engine itself is heavy. Setting up more engines on the aerodynamic boat will increase the forward resistance due to excessive load and reduce the speed of the aerodynamic boat; (2) Complex superstructure: Most aerodynamic boats have a dedicated engine room for engine installation. However, the space in the engine room is still limited. The presence of more engines will lead to a complex superstructure of the power system and a large weight, which is not conducive to the maintenance and installation of the aerodynamic boat. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a power system that can balance the relationship between power and load and helps simplify the superstructure, as well as an aerodynamic all-terrain vessel using this power system.

[0005] The present invention adopts the following technical solution:

[0006] This utility model provides a power system, including a belt reducer, an engine, and a propeller. Multiple belt reducers and propellers are provided, and the number of belt reducers and propellers is consistent. Multiple belt reducers are all mounted on the output shaft of the same engine through their own driving pulleys. Each propeller is mounted and fixed to a driven pulley on a belt reducer through its own rotation shaft.

[0007] Preferably, it also includes a control unit, which is connected to the engine signal and controls the engine speed to vary between 0% and 105%.

[0008] Preferably, the control unit is a microcontroller or a PLC.

[0009] Preferably, the belt reducer includes a driving pulley, a driven pulley, and belt rings. Multiple belt rings are simultaneously wound around the driving pulley and the driven pulley in a taut state. The outer walls of the driving pulley and the driven pulley are in close contact with the inner rings of the belt rings.

[0010] Preferably, both the driving pulley and the driven pulley are provided with multiple belt grooves, and the number of belt grooves on the driving pulley and the driven pulley is the same. Each belt ring is simultaneously embedded in one belt groove of the driving pulley and one belt groove of the driven pulley.

[0011] This utility model also provides an aerodynamic all-terrain vessel, which adopts any of the above-mentioned power systems, with the engine located at the stern and an even number of propellers symmetrically arranged on both sides of the stern along the central axis.

[0012] Preferably, an engine mount is installed at the stern of the hull, and the engine is mounted on the engine mount.

[0013] Preferably, a propeller bracket is installed at the stern of the hull, and the propeller is mounted on the propeller bracket.

[0014] Preferably, it also includes a fuel tank, which is located near the engine and supplies fuel to the engine.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] The power system of this invention features a single engine paired with a belt reducer to drive multiple propellers, which balances the relationship between power and load, ensuring the speed of the aero-powered all-terrain vehicle. In addition, since only one engine is used, it also helps to simplify the superstructure of the power system, making it easier to inspect and install the aero-powered all-terrain vehicle.

[0017] The aerodynamic all-terrain vessel of this invention greatly improves its power performance and carrying capacity by adopting the aforementioned power system. Attached Figure Description

[0025] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. These embodiments are only used to illustrate this utility model and are not intended to limit it.

[0026] In the description of this utility model, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0029] See Figure 1 This embodiment provides a power system including a belt reducer 1, an engine 2 and a propeller 3. Multiple belt reducers 1 and propellers 3 are provided, and the number of belt reducers 1 and propellers 3 is consistent. Multiple belt reducers 1 are all mounted on the output shaft 201 of the same engine 2 through their own driving pulleys. Each propeller 3 is mounted and fixed to a driven pulley on a belt reducer 1 through its own rotating shaft 301.

[0030] The power system in this embodiment uses a single engine 2, which is paired with a belt reducer 1 to drive multiple propellers 3. This balances the relationship between power and load, ensuring the speed of the aero-powered all-terrain vehicle. In addition, since only one engine is used, it also helps to simplify the superstructure of the power system, making it easier to inspect and install the aero-powered all-terrain vehicle.

[0031] It should be noted that belt reducers transmit power using the friction between the belt and pulleys, achieving a reduction effect through the diameter ratio of the driving and driven pulleys. They offer advantages such as simple structure, easy installation, low noise, and vibration damping. However, they also have disadvantages such as low transmission efficiency and weak load-bearing capacity. Therefore, the power system of this embodiment is particularly suitable for boats where high transmission precision and efficiency are not required.

[0032] Preferably, the power system of this embodiment also includes a control unit, which is connected to the engine 2 by a signal and controls the speed of the engine 2 to vary between 0% and 105%.

[0033] The control unit can adjust the speed of engine 2 as needed. However, since multiple propellers 3 on the power system require a single engine 2 to drive them, engine 2 may operate at speeds exceeding its rated speed. When engine 2 speed exceeds 100%, it means that engine 2 is operating at overspeed. Prolonged overspeed may damage engine 2. Therefore, the control unit needs to limit the speed of engine 2 to a safe threshold of 105% to avoid excessive wear or damage to engine 2.

[0034] Preferably, the control unit is a microcontroller or a PLC.

[0035] Preferably, the belt reducer 1 includes a driving pulley, a driven pulley, and multiple belt rings, which are simultaneously wound around the driving and driven pulleys in a taut state. The outer walls of both the driving and driven pulleys are in close contact with the inner rings of the belt rings. The arrangement of multiple belt rings on the belt reducer 1 ensures transmission efficiency and avoids the need for ship shutdown and maintenance if a single belt ring is damaged.

[0036] Preferably, both the driving pulley and the driven pulley are provided with multiple belt grooves, and the number of belt grooves on the driving pulley and the driven pulley is the same. Each belt ring is simultaneously embedded in one belt groove of the driving pulley and one belt groove of the driven pulley.

[0037] This embodiment also provides an aerodynamic all-terrain vehicle, employing the aforementioned power system, with the engine 2 located at the stern and an even number of propellers 3 symmetrically arranged on both sides of the stern along the central axis. The symmetrical arrangement of the even number of propellers 3 ensures the combined thrust provided by each propeller, enabling the all-terrain vehicle to travel in a straight line.

[0038] Preferably, an engine mount is installed at the stern of the hull, and the engine 2 is mounted on the engine mount.

[0039] Preferably, in this embodiment, the engine base is made of metal.

[0040] Preferably, a propeller bracket is installed at the stern of the hull, and the propeller 3 is mounted on the propeller bracket.

[0041] Preferably, in this embodiment, both the engine base and the propeller bracket are bolted to the hull.

[0042] Preferably, the aerodynamic all-terrain vessel of this embodiment also includes a fuel tank, which is located near the engine 2 and supplies fuel to the engine 2.

[0043] See Figure 1 In one specific embodiment, the power system of the aerodynamic all-terrain vehicle has only two propellers 3. The two propellers 3 are symmetrically arranged on both sides of the stern along the central axis, and both propellers 3 are located on propeller brackets. The speed of the engine 2 is varied between 0% and 105% by the control of the microcontroller. The thrust of the two propellers 3 is consistent, ensuring the stable straight-line travel of the aerodynamic all-terrain vehicle.

[0044] Clearly, thanks to its reliable and stable power system design, this new type of aerodynamic all-terrain vessel can safely and stably navigate in various environments such as water, snow, icy rivers, deserts, and river swamps, and complete corresponding transportation, transport, and rescue missions.

[0045] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principle of the present utility model. These improvements and substitutions should also be considered within the protection scope of the present utility model, such as the propulsion method of a single engine 2 driving a single propeller 3.
