[0002] An amphibious boat is a multifunctional carrier that combines air-cushion boat and aircraft technologies, and can realize land travel, water navigation and low-altitude flight in multiple scenarios, and has important application value in emergency rescue, island transportation, field exploration and other fields due to its cross-environment passing capability; in the prior art, the amphibious boat is usually based on an air-cushion boat, which is powered by a propulsion fan and realizes low-altitude lift through a wing, thereby preliminarily meeting the basic requirements of carrying multiple people and large-load transportation.

[0003] When the amphibious boat is flying and navigating at low altitude, the propulsion fan needs to rotate at high speed to provide thrust, and during this process, when birds move relative to the amphibious boat, i.e. the heading of the amphibious boat corresponds to the flight direction of the birds, the amphibious boat navigates or flies at low altitude towards the birds, and the birds navigate or fly at low altitude towards the amphibious boat, especially predatory birds such as seagulls and sea eagles, the relative speed of the two increases, which makes it difficult for the birds to react and collide with the fan blades; such collision can easily cause deformation and fracture of the fan blades, causing power system failure and threatening navigation safety.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of the present invention will now be described.

[0030] Example 1: A high-capacity amphibious vessel capable of carrying multiple people, such as Figures 1-6 As shown, the device includes an air-cushioned boat 1, a base 4 fixed to the top of the air-cushioned boat 1, a raised seat 14 fixed to the middle of the top of the base 4, a first baffle 12 fixed to the outer ring of the raised seat 14, a second baffle 13 fixed to the inner ring of the outer cylinder 5, and drainage outlets 11 on both sides of the base 4. The raised seat 14 can raise the installation position of the fully enclosed electric cylinder 8, reducing the immersion of seawater on the bottom of the fully enclosed electric cylinder 8 when water is stored in the outer cylinder 5. The first baffle 12 and the second baffle 13 are staggered to form a simple maze structure. With the multiple drainage outlets 11 arranged in a ring array, the seawater splashed into the outer cylinder 5 can be quickly discharged, and the waves can be prevented from flowing back through the drainage outlets 11 to impact the fully enclosed electric cylinder 8, thereby improving the equipment's protection capability in the water environment. The top of the lifting seat 14 is provided with a fully enclosed electric cylinder 8, and the output end of the fully enclosed electric cylinder 8 is connected with a cover plate 10 and a reflective flash seat 6 through a support seat 9. The support seat 9 and the cover plate 10 are in sliding connection with the outer cylinder 5. The reflective flash seat 6 is in rotary connection with the support seat 9 and the cover plate 10. The reflective flash seat 6 is made of 316L stainless steel material. The top of the reflective flash seat 6 is in the shape of a honeycomb sphere. The top of the reflective flash seat 6 is subjected to mirror polishing treatment. The surface of the reflective flash seat 6 is provided with a passivation film. A plurality of fan blades 15 are arranged in an annular array around the outer periphery of the reflective flash seat 6. The longitudinal section of the fan blade 15 is in the shape of a "C" letter. The transverse section of the fan blade 15 is in the shape of a circular arc. The sliding connection of the support seat 9 and the cover plate 10 with the outer cylinder 5 ensures the stable lifting of the reflective flash seat 6 under the driving of the fully enclosed electric cylinder 8. The rotary connection of the reflective flash seat 6 with the support seat 9 and the cover plate 10 enables the reflective flash seat 6 to rotate independently of the support structure, thereby ensuring the continuity of the flash effect. The reflective flash seat 6 is made of 316L stainless steel material and is provided with a passivation film, which can resist the corrosion of high salt mist and humid environment. The top honeycomb spherical design and mirror polishing treatment can maximize the reflection angle of light and improve the flash coverage range. The fan blade 15 with the longitudinal section in the shape of a "C" letter and the transverse section in the shape of a circular arc can efficiently capture the external airflow and the airflow sucked by the propeller 2, thereby enhancing the rotary driving force and ensuring the stable rotation of the reflective flash seat 6. The top of the base 4 is connected with the outer cylinder 5 on both sides. The top of the outer cylinder 5 is provided with a light supplement lamp 7. The light supplement lamp 7 is provided with three or six light supplement lamps 7 arranged in an annular array. The light supplement lamp 7 is obliquely arranged. The light supplement lamp 7 corresponds to the reflective flash seat 6. The three or six light supplement lamps 7 arranged in an annular array correspond to the light reflection area of the reflective flash seat 6 in a precise manner at the angle of the oblique arrangement, thereby ensuring that the cold light uniformly covers the reflective surface.

[0031] Referring to Figure 1 In the above embodiment, the top of the air cushion boat 1 is provided with the propeller fan 2 on both sides. When the propeller fan 2 rotates at a high speed, it can provide forward driving force for the tri-hull boat and generate upward lift component. The air cushion boat 1 is connected with the wing 3 on both sides. The wing 3 adopts a double tail support layout. The wing 3 with the double tail support layout can enhance the structural stability during low-altitude flight and improve the lift efficiency. The two can work together to make the tri-hull boat have more reliable controllability and load capacity during low-altitude flight.

[0032] Embodiment two On the basis of the above embodiment one, in order to facilitate the replacement of the structure, the following settings are made.

[0033] Referring to Figures 2-6In the above embodiment, the outer cylinder 5 is detachably connected with the base 4 by 316L stainless steel bolts, the outer part of the 316L stainless steel bolt is provided with double self-locking washers, the cover plate 10 is semicircular ring-shaped, the cover plate 10 is provided with two, and the two cover plates 10 are detachably connected with the support seat 9 by 316L stainless steel bolts, the detachable connection design of the outer cylinder 5 and the base 4 facilitates quick disassembly and replacement when the outer cylinder or the base is damaged, and reduces the maintenance difficulty; the 316L stainless steel bolt cooperates with the double self-locking washers, can effectively prevent the bolt from loosening when the amphibious vehicle is running, and guarantees the long-term stability of the connection structure; the two semicircular ring-shaped cover plates 10 are adapted to the inner wall of the outer cylinder 5, can reduce friction when the reflection flash seat 6 is lifted, and can also replace the reflection flash seat without disassembling the outer cylinder through the detachable connection mode, thereby significantly simplifying the maintenance process.

[0034] Embodiment three: On the basis of the above embodiment one, in order to facilitate long-term use on the sea, the following settings are made.

[0035] Reference Figures 2-5 In the above embodiment, the light supplement lamp 7 is a ZY-TD6A1-9x3W marine high-power LED lamp of Zhuhai Zhengyuan Optoelectronics, made of 316L stainless steel, with a protection level of IP68, which can emit light stably in a seawater splashing and high humidity environment for a long time, ensuring that the light supplement effect is not affected by harsh environments, and the fully enclosed cylinder 8 is a KLAFB fully enclosed electric cylinder of Kelaituo, made of anodized aluminum alloy, and has a fully enclosed structure, with excellent waterproof and dustproof performance, which can effectively block water vapor and salt mist.

[0036] The implementation principle of the present application is as follows: first, the air cushion boat 1 is used as a basic carrier, the air cushion generated at the bottom supports the overall weight, realizes stable land travel and water surface floating navigation, the propeller fan 2 is installed on the top of the air cushion boat 1 on both sides, inhales air flow and sprays it backward when rotating at high speed, provides forward power and lift basis for the amphibious vehicle, and the wing 3 with a double tail support layout generates upward lift through the pressure difference generated by the airflow passing through the wing surface during low-altitude flight, cooperates with the thrust of the propeller fan 2, so that the amphibious vehicle can smoothly complete low-altitude flight, thereby realizing multi-scene motion switching of land, water surface and low altitude, During the period, the structure design of the fan blade 15 can enhance the capture efficiency of the fan blade 15 to the airflow, so that the fan blade 15 can rotate by itself with the help of external airflow and the airflow sucked by the propeller 2, thereby driving the reflection flash seat 6 to rotate synchronously. The honeycomb ball structure polished by the mirror on the top of the reflection flash seat 6 can efficiently reflect sunlight, forming continuous and multi-angle flash. The 316L surface after mirror polishing has high reflectivity, and the chemical stability of the passivation film is extremely strong. Even if it is exposed to a humid, high-salt or dusty environment for a long time, the surface is not easy to rust, corrode or wear, and the reflection effect can be maintained for several years or even longer. When it is cloudy or insufficiently light, the driver can start the obliquely distributed supplementary light 7 through the control console in the hovercraft 1. The cold light emitted by the supplementary light 7 is reflected by the reflection flash seat 6, ensuring continuous flash effect throughout the day. The cold light source has more blue light components, and birds are more sensitive to ultraviolet light, blue light and red light. The three or six supplementary lights 7 in the annular array increase the uniformity of the supplementary light, so that the supplementary light is not reflected in the direction of the hovercraft 1 when the hovercraft 1 is moving. The side of the hovercraft 1 can also flash, avoiding birds flying from the side of the hovercraft 1 and being sucked into the airflow of the propeller 2. This continuous flash has a wider coverage than the sound wave bird repelling device, and the speed of light propagation is much faster than that of sound, which can make birds perceive the object in front of them earlier and avoid it in time, effectively avoiding bird impact on the propeller 2. During navigation, the outer cylinder 5 can block the direct impact of the sea waves on the fully enclosed cylinder 8. The first baffle 12 and the second baffle 13 form a labyrinth structure, which can timely drain the splashed seawater and prevent the seawater from flowing back and impacting. The drainage port 11 has multiple outlets to ensure that the water in the outer cylinder 5 is uniformly drained from multiple directions, improving the drainage efficiency. The lifting seat 14 reduces the immersion of the water in the bottom of the cylinder, significantly improving the durability of the equipment in complex water environments. When personnel get on and off the boat or carry goods, the driver can start the fully enclosed cylinder 8 through the control console in the hovercraft 1. The fully enclosed cylinder 8 can drive the reflection flash seat 6 to rise and fall, and the reflection flash seat 6 is retracted into the outer cylinder 5, avoiding flash interference during operation. When the fully enclosed cylinder 8 needs to be replaced, the worker can detachably connect the outer cylinder 5 and the base 4 through the 316L stainless steel bolts. The double-stacked self-locking washers outside the bolts can effectively prevent the bolts from loosening during the operation of the amphibious vehicle, ensuring the stability of the connection between the outer cylinder 5 and the base 4. In the prior art, the fully enclosed cylinder 8 is also usually detached by bolts. Since the amphibious vehicle is usually used at sea, the bolts can also be in the form of 316L stainless steel bolts with double-stacked self-locking washers. The two semicircular cover plates 10 are detachably connected with the support seat 9 through 316L stainless steel bolts. When the reflection flash seat 6 is worn or damaged due to long-term use, the support seat 9 and the cover plate 10 can continue to move upwards through the fully enclosed cylinder 8, so that the bolts and nuts on the support seat 9 and the cover plate 10 are completely exposed to the outside. The worker can detach the cover plate 10 to replace the reflection flash seat 6 without the need to disassemble the outer cylinder 5 and other structures.

[0037] Although the embodiments of the present application have been shown and described, the specific embodiments are merely exemplary and are not to be construed as limiting the present application, and the described specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner, and those skilled in the art can make modifications, replacements and variations to the embodiments without creative contribution after reading the specification, and as long as they are within the scope of the claims of the present application, they are protected by the patent law.
