Problems solved by technology

[0007] (1) The design of the mechanical structure is complex and prone to failure. It is necessary to improve the original vehicle power system, increase the transmission structure, and install the steering structure. At the same time, an independent control mechanism must be installed, which is time-consuming and labor-intensive. It is difficult to realize the transmission of the mechanical structure of the wheel. , and it is easy to cause overheating of the universal drive in the wheel when driving, causing danger
[0008] ⑵Easy to damage, the propeller is easy to be bumped when the car is driving, and it is also easy to be scratched by the bottom of the river when navigating in the river, causing the propeller to be damaged
[0009] (3) The cost is high, and the design and modification cost of a set of underwater thrust device is at least tens of thousands of yuan, which is difficult to be practically popularized and applied
[0010] To sum up, the existing propulsion devices basically have problems such as complex structure, easy damage, difficult operation, and high cost, making it difficult to popularize and use
So far, high-end off-road vehicles and military vehicles basically do not have amphibious functions, but the actual vehicles often need to pass through rivers and shoals on the way, especially in bad weather and there will be urban water accumulation, which will There is a problem of blocking vehicles on the road, especially where the infrastructure is not perfect. Therefore, there is an urgent need to develop a propulsion device that can be popularized and applied to realize the amphibious use of vehicles.

Abstract

The invention relates to a centrifugal pump type water jetting propulsion amphibious device. The amphibious device is provided with a centrifugal pump type water jetting propulsion device. The water jetting propulsion device comprises a wheel frame, a transmission shaft, a driving wheel, a centrifugal pump shell and a centrifugal structure. The wheel frame is installed on the lower portion of the amphibious water jetting propulsion device and rotationally provided with the transmission shaft. The driving wheel is coaxially installed at the outer end of the transmission shaft in a driving mode. The transmission shaft drives the driving wheel to rotate. The centrifugal pump shell and the centrifugal structure are coaxially installed on the transmission shaft. The transmission shaft drives the centrifugal structure to rotate coaxially so that water flow can be driven to make centrifugal movement. The centrifugal pump shell and the wheel frame are relatively static. The centrifuged water flow is output through the centrifugal pump shell in a steering mode. The centrifugal pump type water jetting propulsion amphibious device is simple in structure, easy and convenient to maintain, convenient to obtain and capable of achieving the water wading and crossing functions.

Description

technical field [0001] The invention belongs to amphibious devices, in particular to a centrifugal pump type water jet propulsion amphibious device and a working method thereof. Background technique [0002] The concept of amphibious vehicles has been proposed for a long time, but it has not been popularized because of its complex structure, easy damage, and difficult operation. Even high-end off-road vehicles and military vehicles do not have this function. [0003] After searching, the following existing patented technologies and published technologies in similar technical fields. [0004] An amphibious vehicle (CN103917387A) operable in a land mode and a water mode, comprising: a hull; at least one discontinuity (wheel well) disposed in the hull; and at least partially located at the at least one discontinuity ( wheel well) at least one retractable wheel or track assembly. The hull is a planing hull; and the at least one discontinuity (wheel well) is provided in the fro...
