Self-balancing thrusters for ships and aircraft

Abstract

The invention relates to an automatic balancing thruster for naval vessels and air vehicles. The automatic balancing thruster for the naval vessels and the air vehicles comprises a box body, a gravity hammer body is hoisted in the center of the interior of the box body, and the two sides of the gravity hammer body are each provided with a gas supply and exhaust main centre, an upper supporting sliding wheel and a lower supporting sliding wheel; each upper supporting sliding wheel is located over the corresponding gas supply and exhaust main centre, each lower supporting sliding wheel and the gravity hammer body are located on one horizontal line, each gas supply and exhaust main centre comprises a cylinder barrel, and four air through openings are formed in the middle portion of each cylinder barrel and are evenly distributed along the circumference of the cylinder barrel, wherein two opposite air through openings are communicated with a high pressure air inlet pipe, and the other two air through openings are communicated with a high pressure jetting bag through exhaust pipes; a sliding valve element is arranged in each cylinder barrel, the upper end of each sliding valve element is connected with the gravity hammer body through a pulling steel cable, each pulling steel cable is wound around the upper supporting sliding wheel over the sliding valve element and the lower supporting sliding wheel on the other side, and an annular groove is formed in the middle portion of each sliding valve element. According to the automatic balancing thruster, the high pressure air energy storage bag and the high pressure jetting bag can be communicated through gravity, and the sensitivity is high.

Description

technical field [0001] The invention relates to an automatic balancing propeller for ships and aircrafts. Background technique [0002] The patent application with the application publication number of CN 105836109 A discloses a self-balancing propeller for ships, vehicles and aircraft. The self-balancing propeller for ships, vehicles and aircraft includes two water-holding boxes, two boxes The high-pressure air chamber is set above the box, and a partition is set in the middle of the high-pressure air chamber. The partition divides the high-pressure air chamber into two chambers, one chamber is connected to the high-pressure air energy storage bag, and the other chamber is connected to the injection chamber. In the middle of the partition, there is a strip-shaped hole in the partition to connect the two chambers. On one side of the partition, a sliding valve that can slide up and down is provided. The strip-shaped hole of the sliding valve, the strip-shaped hole of the sli...

[0002] The patent application with the application publication number of CN 105836109 A discloses a self-balancing propeller for ships, vehicles and aircraft. The self-balancing propeller for ships, vehicles and aircraft includes two water-holding boxes, two boxes The high-pressure air chamber is set above the box, and a partition is set in the middle of the high-pressure air chamber. The partition divides the high-pressure air chamber into two chambers, one chamber is connected to the high-pressure air energy storage bag, and the other chamber is connected to the injection chamber. In the middle of the partition, there is a strip-shaped hole in the partition to connect the two chambers. On one side of the partition, a sliding valve that can slide up and down is provided. The strip-shaped hole of the sliding valve, the strip-shaped hole of the sliding valve and the strip-shaped hole of the partition are on the same straight line, and the lower end of the sliding valve is connected to the float; since the two sides of the partition and the sliding valve are respectively connected with the high-pressure air energy storage bag and the injection pipe, the two sides The pressure difference squeezes the diaphragm and the sliding valve together, which increases the friction between the diaphragm and the sliding valve, and the buoyancy required for the sliding valve to rise or fall is relatively large, which reduces the self-balancing propeller used by ships, vehicles, and aircraft. sensitivity
