Example Embodiment

[0039] The present invention will be further described below in conjunction with the drawings and embodiments:

[0040] figure 1 Schematic diagram of the entire ship structure. It shows the general components of the amphibious ship. It can be seen from the figure that the ship's water drive is driven by the outboard motor 13, the steering wheel 11 can control its direction, and the electronic accelerator pedal 12 controls the speed of the outboard motor 13. When walking on land, the switch lever 7 switches to the on-land walking mode, and the front wheels 10 and the rear wheels 3 are lowered through the front wheel manual reversing valve 9 and the rear wheel manual reversing valve 8 respectively. When the rear wheel 3 is lowered, The protective cover 4 needs to be opened first. The protective box 1 and the hull 5 are welded and connected. The specific structure of protective box 1 and protective box sealing strip 2 is as follows Image 6 Shown.

Abstract

The invention relates to a rear wheel retracting and protecting mechanism for an amphibious boat. The rear wheel retracting and protecting mechanism is capable of realizing folding and retracting rear wheels during drive in water and sealing the rear wheels by a protection cover. The action of the protection cover and the rear wheels is realized by the extension and shrinkage of a protection box hydraulic cylinder and a rear support leg hydraulic cylinder, and the sequential action of the protection box hydraulic cylinder and the rear support leg hydraulic cylinder is realized by a pressure control type sequential action loop. The rear wheel retracting and protecting mechanism for the amphibious boat comprises protection boxes, wherein the protection boxes are arranged at two sides of the rear part of a boat body; the bottoms of the protection boxes are higher than the bottom of the boat body; the protection boxes are provided with openable and closable protection covers; the contact positions of the protection boxes and the protection covers are sealed; rear wheel hydraulic lifting devices are arranged in the protection boxes; the rear wheels are mounted on the rear wheel hydraulic lifting devices; the protection covers are also connected with hydraulic opening and closing devices; the rear wheel hydraulic lifting devices and the hydraulic opening and closing devices are connected with hydraulic control devices; the hydraulic control devices control the lifting action of the rear wheels and the protection covers in a way of sequential control.

Description

Technical field: [0001] The invention relates to a rear wheel retracting protection mechanism of an amphibious ship. Background technique: [0002] There are currently many types of amphibious ships, but they all have a common problem, that is, the placement and sealing of the wheels when driving in water, which directly affects the resistance of the amphibious ship in water and the degree of corrosion of the wheel mechanism. After searching, the wheels of the current amphibious ship can be classified into two states when traveling in the water. One is that the wheels are not stowed when driving in the water, and the other is that the wheels are folded upward and stowed without a protective sealing device. [0003] Utility model patent: issued by the State Intellectual Property Office on November 4, 2009, the application number is 200820030099.X, and the name is a utility model patent for an amphibious vehicle. The on-land driving mechanism includes the vehicle body, power unit, ...
