Telescopic lateral thruster

Abstract

The invention relates to a telescopic lateral thruster, which comprises a gear box and blades, wherein an installing base is arranged on a boat body, a hollow support pipe passes through the center of the installing base, the top of the hollow support pipe is connected with an upper beam, guide rods positioned at both sides of the hollow support pipe pass through the upper beam, the lower ends ofthe guide rods are connected with the installing base, the tops of the guide rods are connected with a hook base fixed on the boat body, a collision hook is arranged on the hook base, a hook pin postis arranged on the upper beam, two hydraulic oil cylinders are arranged between the installing base and the upper beam, the guide rods and the hydraulic oil cylinders are symmetrically and respectively arranged at both sides of the hollow support pipe, the lower end of the hollow support pipe is provided with the gear box, the hollow support pipe and the gear box are also provided with a support plate, the output end of the gear box is the blades, a round barrel body protection cover is arranged outside the blades of the gear box in a matching way, a pair of stress shafts passes through the support plate, the upper ends of the stress shafts are fixedly connected with the installing base, the lower ends of the stress shafts are connected with a permanent seat arranged on the boat body below the water line, and a transmission shaft is arranged in the hollow support pipe and is connected with the input end of the gear box.

Description

technical field [0001] The invention relates to a thruster, in particular to a telescopic lateral thruster for ships. Background technique [0002] The lateral thruster is an important part to improve the operational performance of the ship. In the traditional lateral thruster, the conduit is generally welded to the hull, resulting in a fixed positional relationship between the centerline of the blade and the waterline of the hull. Although it can also be used for traditional fishing The design of the lateral propeller requires that the blade centerline must be below the light-load waterline. However, since the position of the blade centerline below the light-load waterline is relatively shallow, it will directly affect the propulsion performance of the lateral thruster. For some small yachts, water working platforms, engineering ships and other vessels, due to the limited installation space, if traditional lateral thrusters are used, the position of the blade centerline bel...

Problems solved by technology

[0003] The purpose of the present invention is to provide a novel and reliable marine lateral thruster for the problem that the distance between the center line of the blade and the light-load waterline in the lateral thruster cannot meet the requirements for use.
