Description

Technical Field

[0001] The invention belongs to the technical field of ship and ocean devices, and in particular relates to a propulsion appendage device and a propulsion method for an amphibious vehicle to sail on water. Background Art

[0002] With the continuous development of my country's water transportation and navigation technology, the demand for exploring more types and modes of marine transportation is constantly expanding. Amphibious vehicles, as an emerging force in ocean navigation, are increasingly attracting people's attention. At present, most amphibious vehicles face the problem of insufficient navigation power when sailing on the water. There is no conventional solution. The conversion efficiency of energy power is very poor. It is difficult to be widely used in real marine environment work. Therefore, there is still a lot of room for improvement in the navigation power of amphibious vehicles. Therefore, it is necessary to provide a practical and convenient device and method to enhance the effective conversion of energy power and relatively high navigation power of amphibious vehicles when sailing on the water. Summary of the invention

[0003] The purpose of the present invention is to provide a propulsion appendage device and a propulsion method for an amphibious vehicle to navigate on water, by adjusting the impact force difference between the upper and lower rims of the driving wheel through an arc-shaped baffle with a partition on the inner side, thereby improving the forward power.

[0004] To achieve the above objectives, the present invention provides a propulsion appendage device for an amphibious vehicle to navigate on water, comprising an arc-shaped baffle covering the driving wheel of the amphibious vehicle, wherein a surface of the arc-shaped baffle facing the driving wheel is provided with a plurality of spaced-apart partitions.

[0005] Furthermore, the upper surface of the arc-shaped baffle is movably connected to the fender of the amphibious vehicle to adjust the distance between the arc-shaped baffle and the driving wheel.

[0006] Furthermore, the arc-shaped baffle is movably connected to the fender through a telescopic component, and the connection point is located in the middle of the upper surface of the arc-shaped baffle.

[0007] Furthermore, the arc-shaped baffle is also provided with a circumferential length adjustment component for adjusting the arc length of the arc-shaped baffle, thereby adjusting the circumferential coverage of the arc-shaped baffle on the driving wheel.

[0008] Furthermore, the circumferential length adjustment component is a telescopic plate structure.

[0009] Furthermore, the partitions are arranged at equal intervals, and preferably the surface where each partition is located passes through the center of the driving wheel.

[0010] Furthermore, the coverage of the upper rim of the driving wheel by the arc-shaped baffle is one third to one half of the circumference of the driving wheel rim.

[0011] Furthermore, horizontal thin plates are respectively provided at both ends of the arc-shaped baffle.

[0012] The present invention also provides an amphibious vehicle, comprising any one of the above-mentioned propulsion appendage devices.

[0013] The present invention also provides a method for boosting the above-mentioned amphibious vehicle on water, comprising: adjusting the distance and arc length between the arc baffle and the driving wheel of the amphibious vehicle to adjust the difference in water flow impact force on the driving wheel, thereby adjusting the magnitude of the boosting force. The boosting force is increased by reducing the distance between the arc baffle and the driving wheel of the amphibious vehicle and / or increasing the arc length of the arc baffle.

[0014] In general, the above technical solution conceived by the present invention has the following technical advantages compared with the prior art:

[0015] 1. The present invention forms a flowable space between the inner groove of the arc-shaped baffle and the upper wheel rim of the driving wheel by covering the driving wheel with a baffle on the inner side. The driving wheel generates a flow channel in the flowable space. The water flow impact force on the lower wheel rim does not change significantly. Since there is a vertical baffle in the flow channel of the upper wheel rim, the water flow impacts the vertical baffle and partially offsets the water flow impact force on the upper wheel rim, thereby increasing the impact force difference between the upper and lower wheel rims, thereby improving the forward driving force of the amphibious vehicle when sailing on water. At the same time, it does not affect its original driving ability when driving on land, optimizes the conversion problem of the amphibious vehicle for dual use on water and on roads, and solves the problem of insufficient power when the amphibious vehicle is sailing on water.

[0016] 2. The present invention drives the vertical and circumferential movement of the arc-shaped baffle through the telescopic component and the circumferential length adjustment component, thereby adjusting the size of the flowable space formed between the arc-shaped inner groove of the water flow baffle and the driving wheel rim, so that the resistance in the flow channel through which the water flows changes, thereby improving the forward power of the device and realizing the effective conversion of energy and power.

[0017] 3. The present invention improves the balance stability of the water flow thrust by arranging the baffles at equal intervals; through the horizontal thin plates at both ends of the arc-shaped baffle, the water flow is easily guided to the flowable space formed between the inner groove of the arc-shaped baffle and the wheel rim on the driving wheel, thereby improving the thrust effect.

[0018] 4. The present invention only adds a booster appendage device, without changing the original shape and motion characteristics of the amphibious vehicle, maintaining its original land driving ability and efficiency, and reducing the economic cost of the amphibious vehicle.

[0023] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0024] Example 1

[0025] See also Figure 1 and 2 The present invention provides a propulsion attachment device for an amphibious vehicle sailing on water, comprising an arc-shaped baffle plate 2 covering the driving wheel of the amphibious vehicle, and a plurality of spaced partition plates 3 are arranged on the surface of the arc-shaped baffle plate 2 facing the driving wheel. The arc-shaped opening direction of the arc-shaped baffle plate 2 faces the driving wheel, and the side of the arc-shaped baffle plate 2 facing the driving wheel is called the inner surface, and the side away from the driving wheel is called the upper surface.

[0026] With such arrangement, when the amphibious vehicle is sailing on the water surface, the driving wheel is submerged in the water surface, and after the motor rotates, the concave and convex surface of the driving wheel rim stirs the water flow to generate flowing water, and the water flow impact force on the upper rim is approximately equal to the force on the lower rim, and the force direction is opposite, resulting in an overall impact force difference. After the inner groove of the arc-shaped baffle of the booster attachment device covers the upper rim of the driving wheel, a flowable space is formed between the inner groove of the arc-shaped baffle and the upper rim of the driving wheel, and the driving wheel generates a flowing waterway in the flowable space, and the water flow impact force on the lower rim does not change significantly. Since there is a vertical partition in the flowing waterway of the upper rim, the water flow impacts the vertical partition and partially offsets the water flow impact force of the upper rim, thereby increasing the impact force difference between the upper and lower rims. By changing the vertical distance between the end of the partition and the upper circumference of the driving wheel and the length of the flowing waterway, the overall impact force difference can be enhanced, thereby solving the problem of insufficient forward power when the amphibious vehicle is sailing on water.

[0027] In particular, the baffles 3 are arranged at equal intervals, and preferably, the surface where each baffle 3 is located passes through the center of the circle of the driving wheel. The baffles 3 are arranged along the width direction of the arc-shaped baffle 2 (that is, the baffles are parallel to the width direction of the arc-shaped baffle 2), and are spaced apart in the length direction of the arc-shaped baffle 2. One end of the baffle 3 is connected to the inner groove surface of the arc-shaped baffle 2, and the other end slightly extends out of the inner groove of the arc-shaped baffle 2 to point to the direction of the driving wheel hub, maintaining a vertical distance from the driving wheel rim, and resisting part of the water flow impact in the flowable space formed between the baffle 3 and the driving wheel rim. The forward power can also be regulated to a certain extent by adjusting the height of the baffle 3 (that is, the height extending from the connection end with the arc-shaped baffle 2 to the driving wheel direction) and the spacing.

[0028] In particular, the coverage of the upper rim of the driving wheel by the arc-shaped baffle 2 is one third to one half of the circumference of the driving wheel rim.

[0029] Horizontal thin plates 5 are respectively provided at both ends of the arc-shaped baffle plate 2 to facilitate the water flow to be directed to the flowable space formed between the inner groove of the arc-shaped baffle plate 2 and the upper rim of the driving wheel.

[0030] The upper surface of the arc baffle 2 is movably connected to the fender of the amphibious vehicle, and is used to adjust the distance between the arc baffle 2 and the driving wheel, thereby changing the height of the flowable space formed between the inner groove of the arc baffle covering the upper rim of the driving wheel and the driving wheel rim. Specifically, the arc baffle 2 is movably connected to the fender through a telescopic component (not shown in the figure), and the connection point is located in the middle of the upper surface of the arc baffle 2, such as Figure 1 The part 1 connected with the fender telescopic device. The telescopic assembly can be a spring telescopic assembly. When the spring is extended and retracted, the arc baffle 2 moves vertically, so that the vertical distance between the end of the vertical partition 3 in the groove of the arc baffle 2 and the wheel rim changes accordingly.

[0031] The arc-shaped baffle plate 2 is also provided with a circumferential length adjustment component 4 for adjusting the arc length of the arc-shaped baffle plate 2, and further adjusting the circumferential coverage of the arc-shaped baffle plate 2 to the driving wheel.

[0032] In some embodiments, the circumferential length adjustment component 4 is a telescopic plate structure, for example, an arc-shaped baffle is sleeved in another plate-type tube, and a limiting structure is provided so that the arc-shaped baffle can be pulled out and pushed in from the plate-type tube to adjust the arc length. In particular, the telescopic plate is provided as a transmission telescopic structure, and the two layers of arc-shaped baffles are connected by a gear transmission device (not shown in the figure). When the gear rotates, the baffle extends in the circumferential direction, so that the circumferential coverage distance between the groove in the baffle and the wheel rim changes accordingly. In some preferred embodiments, a foldable partition can also be provided on one layer of the arc-shaped baffle. After it is extended in the circumferential direction, the folded partition can be opened to ensure that the partitions can still be distributed at equal intervals.

[0033] When the driving wheel rotates, the wheel rim stirs the water flow to generate water in the flowable space formed between the inner groove of the arc-shaped baffle 2 and the upper rim of the driving wheel. The water flow impacts the partition 3 to generate resistance, and the water flow impact force of the upper rim of the driving wheel is reduced. The water flow impact force of the lower rim of the driving wheel is greater than that of the upper rim, thereby increasing the water flow impact force difference. When the arc-shaped baffle 2 descends and extends circumferentially, the vertical distance between the end of the vertical baffle 3 and the rim is reduced, and the circumferential distance covered by the arc-shaped baffle 2 on the rim is increased, the resistance is increased, the water flow impact force difference is increased, and the forward driving force is increased.

[0034] Example 2

[0035] The present invention provides an amphibious vehicle, comprising the booster attachment device described in Example 1. Specifically, the amphibious vehicle comprises a vehicle body and a driving wheel, and an arc-shaped baffle plate 2 covering the driving wheel is arranged above the driving wheel. A telescopic device connected to a fender is arranged on the upper surface of the arc-shaped baffle plate 2, and transmission devices are arranged on both sides of the arc-shaped baffle plate 2; and a horizontal thin plate is arranged at the end of the arc-shaped baffle plate 2.

[0036] The booster attachment device is located on the lower surface of the fender of the amphibious vehicle, and the two sides of the baffle are connected to each other through a transmission device, and the arc-shaped baffle 2 covers the upper rim of the driving wheel. The outer contour of the baffle is arc-shaped and covers the upper rim of the driving wheel; the inner groove of the arc-shaped booster attachment device is vertically arranged with multiple baffles pointing to the wheel hub, and each baffle is evenly arranged at equal intervals, and the end of the baffle maintains a vertical distance from the driving wheel, and the vertical distance can be changed by a telescopic device.

[0037] Example 3

[0038] The present invention provides a method for boosting the navigation of an amphibious vehicle on water, wherein an arc-shaped baffle plate with a partition plate inside is covered above a driving wheel, so that a flowable space is formed between an inner groove of the arc-shaped baffle plate and an upper wheel rim of the driving wheel, thereby adjusting the impact force difference between the upper and lower wheel rims of the driving wheel, thereby improving the forward power of the amphibious vehicle.

[0039] Furthermore, by adjusting the distance between the arc baffle 2 and the driving wheel of the amphibious vehicle and the arc length, the size of the flowable space can be adjusted, and then the difference in water flow impact force on the driving wheel can be adjusted, ultimately achieving the adjustment of the size of the boost force.

[0040] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
