Embodiment Construction

[0015] exist Figure 1-2 In the illustrated embodiment, the shaft (5), the impeller (2) coaxially mounted on the shaft (5) and the casing (1) with the water inlet (3) and the water outlet (7), wherein the shaft (5) It is installed on the casing (1), the impeller (2) is located in the casing (1), the casing (1) has a protrusion (6) on the outer circle, and the water outlet (7) is located in the radial direction of the outer circle of the casing (1). The water inlet (3) is located in the axial direction of the housing (1) and is concentric with the shaft (5). The end of the shaft (5) away from the impeller (2) is equipped with a flange (4). The impeller (2) is a centrifugal impeller.

[0016] During use, the fastening nuts of the driving wheel tires on the amphibious vehicle are unloaded, and the water propeller flange (4) of the amphibious vehicle is fixed on the axle close to the wheel hub by using nuts and bolts. A block (8) is installed on the car body, the block (8) is po...

Abstract

The invention provides an amphicar above-water propeller, which is provided with a shaft (5), impellers (2) coaxially arranged on the shaft (5) and a shell with a water inlet (3) and a water outlet (7); wherein, the shaft (5) is axially arranged on the shell (1); the impellers (2) are arranged in the shell (1); the circumference of the shell (1) is provided with a bulge (6); the water outlet (7) is arranged at the external round in the radial direction of the shell (1). One end of the shaft (5) which is far away from the impeller (2) is provided with a flange (4). When used, the tightening nut of the tyre of a driving wheel on the vehicle is removed, and the flange (4) is tightly attached to the hub and fixed on the axle by nuts and bolts. The vehicle body is provided with a retaining block (8) which is arranged between two bulges on the circumferential shell. When the vehicle enters the water, the impeller rotates with the axle; the propeller sucks the water from the water inlet and drains the water out of the water outlet. The retaining block and the bulge restrict the shell to rotate with the impeller and lead the water outlet to be aligned with the rear. The reaction force of the water pushes the vehicle advance. When backing, the restriction of the retaining block and the bulge leads the water outlet to be aligned with the frontage and the reaction force of the water pushes the vehicle to back.

Description

technical field [0001] The invention belongs to the field of propulsion devices for amphibious vehicles using water as the medium and using the principle of jetting or reaction force. Background technique [0002] At present, what the propeller on the water of known amphibious vehicle adopts is propeller, and its transmission structure is complicated, and maintenance is difficult, and is easily damaged when used in the military field. Contents of the invention [0003] The technical problem solved by the invention is to provide a high-efficiency, easy-to-use water propeller for amphibious vehicles. [0004] The present invention is realized like this, see Figure 1-2 , a water propeller for amphibious vehicles, which has a shaft (5), an impeller (2) coaxially mounted on the shaft (5), and a casing (1) with a water inlet (3) and a water outlet (7) ), wherein the shaft (5) is axially installed on the casing (1), the impeller (2) is located in the casing (1), the outer circl...
