Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings.

[0019] Figure 1 to Figure 9 for a cycle. figure 1 The hydraulic system is in the initial state: the left side of the reversing valve (13) leads, the reversing valves (7) and (8) are in the initial state, and the upper left oil circuit forms a passage. figure 2 High-pressure oil enters the hydraulic cylinder from the upper left passage to make the push rod move downwards to squeeze the water in the water tank to the right until the water pressure plate reaches the bottom of the water tank, and the hull moves forward to the left. image 3 Reversing valve (13) changes direction, makes upper left oil circuit be in the closed state with certain pressure, and upper right oil circuit forms passage. Figure 4 High-pressure oil enters the right hydraulic cylinder from the upper right passage, and the water in the water tank is squeezed out to the right by promoting the down...

Abstract

The invention discloses a water pressing type propeller based on hydraulic transmission. The propeller is composed of a hydraulic transmission system and a water pressing system; an upper oil path and a lower oil path of a left and right hydraulic cylinder are controlled to be connected or disconnected through reversing of a reversing valve, pressure difference is formed between the upper portion and the lower portion of the hydraulic cylinder, a hydraulic push rod is made to move up and down so as to drive a water pressing plate to move up and down, and water suction and water pressing are achieved. The moving up and down speed of the water pressing plate can be changed by changing the reversing speed of the reversing valve, and therefore water suction speed and water pressing speed can be changed so as to change the propelling speed. The water pressing type propeller based on hydraulic transmission can be used for civil ships or military warships and submarines.

Description

technical field [0001] The invention relates to a pressurized water propeller driven by a hydraulic transmission system. Background technique [0002] The thruster is a propulsion device widely used in aerospace, ships, automobiles and other vehicles. It converts the power provided by the power device on the vehicle into thrust to push the vehicle forward. It is an indispensable equipment on the vehicle. At present, common ship propellers include propeller propellers and water jet propellers. The traditional propeller propeller has complex structure, high cost and difficult maintenance. At the same time, the turbulent flow and cavitation generated by the high-speed rotation of the propeller produce great resistance, consume a lot of energy, shorten the life of the blade, and cause noise, vibration and other hazards. The core component pump of water jet propulsion is generally axial flow pump, mixed flow pump or centrifugal pump, although acceleration, high speed, shallow d...
