Description

Technical Field

[0001] This invention relates to the field of amphibious vessel technology and provides an amphibious beach work vessel. Background Technology

[0002] In coastal areas, such as the Yellow Sea in my country, there are large tidal flat areas. Coastal tidal flats generally refer to the tidal zones between high and low tide levels. Due to the tidal action, the tidal flats are sometimes submerged and sometimes exposed. The upper part is often above water, while the lower part is often submerged. Tidal flats have great development potential. However, due to the special geographical features of tidal flats, neither ships nor vehicles can travel freely on them. Even the amphibious vehicles or ships that are commonly used today mainly work by adding wheels to ordinary ships. They move in the water using propulsion and on land using wheels. However, these amphibious vehicles can only move in water deep enough and on relatively solid ground. In shallow, muddy tidal flats where the water level changes with the tides, wheels and propulsion cannot be used effectively. Therefore, a special amphibious operation equipment adapted to the tidal flat terrain is needed to facilitate the development of tidal flat areas. Summary of the Invention

[0003] Therefore, the present invention provides an amphibious beach work vessel, which uses at least four amphibious impellers to move the work vessel in shallow water areas. Each of the four amphibious impellers is driven independently, and different speeds and directions of rotation enable flexible steering. At the same time, land-moving wheels can be fitted on the outside of the amphibious impellers to enable movement on flat land.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an amphibious beach workboat, comprising a hull, wherein at least two amphibious drive devices are respectively provided on the left and right sides of the hull, the amphibious drive device comprising a drive motor and an amphibious impeller, the amphibious impeller comprising a rotating hub connected to the output shaft of the drive motor, and a plurality of actuating blades being arranged in a ring on the outer side of the rotating hub.

[0005] Furthermore, the amphibious drive device also includes an impeller lifting device, which is used to control the drive motor and the lifting of the amphibious impeller.

[0006] Furthermore, the hull is equipped with a hydraulic station, the drive motor is a hydraulic motor, and the impeller lifting device includes two hydraulic cylinders, which are respectively located on both sides of the drive motor. The hydraulic station is used to control the operation of the hydraulic motor and the hydraulic cylinders.

[0007] Furthermore, the amphibious impeller is detachably fitted with a land-moving wheel, the land-moving wheel including a rigid connecting wheel rim, the rigid connecting wheel rim being detachably and fixedly connected to the amphibious impeller, and an elastic tire being provided on the outer side of the rigid connecting wheel rim.

[0008] Furthermore, the inner side of the rigid connecting wheel rim is provided with a plurality of blade limiting grooves, which are adapted to a plurality of actuating blades on the outer side of the rotating hub. The plurality of actuating blades can be inserted into the corresponding blade limiting grooves, and the blade limiting grooves and actuating blades are detachably connected by a bolt fastening mechanism.

[0009] Furthermore, several vibrators are installed at the bottom of the hull.

[0010] Furthermore, a propeller is rotatably mounted at the rear of the hull.

[0011] Furthermore, an impeller splash guard is provided above the amphibious drive device.

[0012] Furthermore, the hull is equipped with a digging device, which includes a rotating base. The rotating base drives a first digging arm, which is connected to a second digging arm. The first digging arm drives the second digging arm to rotate via a hydraulic cylinder, and the second digging arm also drives the working bucket to rotate via a hydraulic cylinder.

[0013] Furthermore, the hull is equipped with storage compartments.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. In this invention, the amphibious beach workboat travels in shallow waters through four independently driven amphibious impellers. Especially in shallow waters, the amphibious impellers move by moving the bottom mud and sand by moving the blades, thus avoiding running aground. In deep waters, the amphibious impellers can also assist in turning the hull.

[0016] 2. The outer side of the amphibious impeller can be fitted with detachable land-based wheels, which can be used to temporarily move on flat land, facilitating the transfer of the amphibious beach work vessel. Attached Figure Description

[0031] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0032] Example 1, refer to Appendix Figure 1 Appendix Figure 2The present invention provides an amphibious beach work vessel, including a hull 100. Several vibrators 500 are installed at the bottom of the hull 100. These vibrators 500 are existing technology and can generate regular vibration waves at the bottom of the hull 100. If the bottom of the hull 100 is adhered to by mud and sand in shallow water, the vibrators 500 can shake off this mud and sand, preventing the hull 100 from becoming stuck. At least two amphibious drive devices 200 are respectively installed on the left and right sides of the hull 100. Each amphibious drive device 200 includes a drive horse. The amphibious drive unit 200, amphibious impeller 210, and impeller lifting device 230 are included. In this embodiment, the number of amphibious drive units 200 is preferably four, that is, two amphibious drive units 200 are respectively arranged on the left and right sides of the hull 100. This structure is similar to that of an ordinary car, which minimizes cost while ensuring stable operation. An impeller splash guard 110 is provided above the amphibious drive unit 200. The impeller splash guard 110 is used to prevent debris or bottom sediment from being brought into the hull 100 when the amphibious impeller 210 rotates. Figure 3As shown, the amphibious impeller 210 includes a rotating hub 211 connected to the output shaft of the drive motor 220. Several actuating blades 212 are arranged in a ring around the outer side of the rotating hub 211. The impeller lifting device 230 controls the lifting of the drive motor 220 and the amphibious impeller 210. The hull 100 is equipped with a hydraulic station 300 as the total power output. The drive motor 220 is preferably a hydraulic motor, while the impeller lifting device 230 includes two hydraulic cylinders, which are respectively located on both sides of the drive motor 220. The hydraulic station 300... 00 is used to control the operation of hydraulic motors and hydraulic cylinders. Each amphibious drive unit 200's drive motor 220 and impeller lifting device 230 can operate independently. Simultaneously, a propeller 400 is rotatably mounted at the rear of the hull 100. The propeller 400 is existing technology; its basic structure involves driving a propeller to rotate via a drive device such as an electric motor, diesel engine, or hydraulic motor, thereby propelling the hull 100 in water. When operating in deep water, the propeller 400 and the amphibious impeller 210 work together... The propulsion system allows the hull 100 to move at a relatively high speed. Simultaneously, the speed difference between the amphibious impellers 210 on both sides of the hull 100 enables it to easily turn. Compared to traditional rudder steering, this steering method has a smaller turning radius and provides more precise control of the hull 100. Furthermore, the reverse rotation of the amphibious impellers 210 allows for rapid stopping of the hull 100. When operating in shallow water areas such as shoals, the propeller 400 is rotated to leave the water, preventing the propeller from contacting the surface. At the same time, after the propeller 400 rotates out of the water, it is also convenient to clean the propeller of the propeller 400. At this time, the movement of the hull 100 mainly relies on the amphibious impeller 210. The agitator blades 212 of the amphibious impeller 210 contact the mud and sand on the bottom of the water. Through the reaction force of the agitator blades 212 moving the mud and sand, the hull 100 can move on the shallows, avoiding the hull 100 running aground and losing its mobility. The steering ability also relies on controlling the speed difference between the amphibious impellers 210 on both sides of the hull 100 to achieve the steering function.

[0033] Example 2, refer to Appendix Figure 4 Based on Example 1, a land-based mobile wheel 240 can be detachably fitted onto the outside of the amphibious impeller 210. The specific structure is shown in the attached figure. Figure 5As shown, the land-based mobile wheel 240 includes a rigid connecting rim 241. A plurality of blade limiting grooves 243 are annularly arranged on the inner side of the rigid connecting rim 241. These blade limiting grooves 243 are adapted to a plurality of actuating blades 212 on the outer side of the rotating hub 211. The actuating blades 212 can be engaged into their corresponding blade limiting grooves 243, and the blade limiting grooves 243 and the actuating blades 212 are detachably connected by a bolt fastening mechanism. Simultaneously, an elastic tire 242 is provided on the outer side of the rigid connecting rim 241. The elastic tire 242, like common car tires, is a round rubber tire. The round land-based mobile wheel 240 enables the original amphibious beach workboat to... Having the ability to move in both deep water and shallow water, it also has the ability to move on flat land. When the hull 100 needs to be moved to a flat land location, the amphibious impeller 210 is first raised by the impeller lifting device 230 until the bottom of the hull 100 touches the ground. At this time, the amphibious impeller 210 is suspended in the air. Then, the operators install the land-moving wheels 240 on the outside of the amphibious impeller 210. Then, the amphibious impeller 210 is lowered by the impeller lifting device 230 until the elastic tires 242 touch the ground, while the bottom of the hull 100 is raised to a safe height. After that, the amphibious impeller 210 with the land-moving wheels 240 installed is used for land movement.

[0034] Example 3, refer to Appendix Figure 6 Based on Embodiment 1 or Embodiment 2, the hull 100 is further provided with a digging device 600. The digging device 600 includes a rotating base, a first digging arm driven by the rotating base, a second digging arm driven by the first digging arm, the first digging arm driving the second digging arm to rotate by a hydraulic cylinder, and the second digging arm driving the working bucket to rotate by a hydraulic cylinder. The digging device 600 can further expand the functionality of the amphibious beach work vessel, such as dredging sand in shallow waters.

[0035] Example 4, refer to Appendix Figure 7 Based on Embodiment 1 or Embodiment 2, a storage compartment 120 is provided on the hull 100. The storage compartment 120 enables fishing operations. For example, when aquaculture of shellfish is carried out in shallow waters, the amphibious beach workboat with the storage compartment 120 in this embodiment can be used to harvest the finished products.
