Wireless steering/braking device for pneumatic propulsion type ship body

Abstract

The invention discloses a wireless steering / braking device for a pneumatic propulsion type ship body and belongs to the field of transportation vehicles in wet lands, shallow water regions, ice regions and snow regions. The device comprises two parts: namely a steering / braking control mechanism and a steering / braking actuating mechanism. The ship steering can be conducted in a manual steering modeor a wireless steering mode. Therefore, the switching between steering modes can be realized through the manual steering mode. In the wireless steering mode, steering angle and steering speed signalsare processed and then are wirelessly transmitted. A left rudder steering motor and a right rudder steering motor drive a left rudder and a right rudder to rotate according to the same angle and thesame direction. In the manual steering mode, a steering engine drives a steering pull wire to move. The steering pull wire drives the left rudder and the right rudder to rotate at the same angle in the same direction. The ship steering is achieved after the propelling force direction is changed. During braking, the left rudder and the right rudder rotate at the same angle in opposite directions. Therefore, the air resistance is increased, and the ship body braking is achieved. The labor intensity of a driver can be effectively reduced, and the braking effect is improved.

Description

technical field [0001] The invention belongs to the steering and braking technology in the field of transportation vehicles in wetlands, shallow water and ice and snow regions, and relates to a wireless steering / braking device for a pneumatically propelled hull. Background technique [0002] The pneumatic propulsion hull is a flat-bottomed hull that is propelled by an engine-driven propeller to generate an airflow backwards. It relies on the rudder behind the propeller to control the direction. It is often used in wetlands, shoals and other places where underwater propellers are not suitable, especially in Wetland exploration, protection and law enforcement, development operations, disaster relief and sightseeing, etc., have incomparable characteristics of other transportation vehicles. [0003] At present, when the pneumatic propulsion hull on the market turns, the driver first operates the steering wheel to drive the steering cable to move, and the linkage mechanism connec...

AI Technical Summary

Problems solved by technology

[0004] The deficiencies of the above-mentioned steering and braking methods of the pneumatic propulsion hull mainly lie in the following: when turning, it relies on the manual method of "wired" connection, the degree of automation is low, and the operating environment of the propulsion hull has certain limitations, especially for fixed-point cruise In the data collection working condition, not only the labor intensity of the driver is increased, but also the frequent and long-term friction of the mechanical connection parts will lead to a decrease in steering reliability; when braking, it only relies on the passive braking force composed of water resistance and wind resistance, and its braking The effect is poor, the braking reliability is low, and it cannot cope with the working conditions that require emergency braking
