Ship transverse-movement windscreen wiper and control method of ship transverse-movement windscreen wiper

Abstract

The invention relates to a ship transverse-movement windscreen wiper which comprises two belt wheel mechanisms, windscreen wiper trolleys, motors and a sensor, wherein the belt wheel mechanisms are symmetrically arranged on a windscreen wiper body, the windscreen wiper trolleys and the motors are arranged on the two belt wheel mechanisms respectively, and the sensor is arranged on any one of the belt wheel mechanisms. The ship transverse-movement windscreen wiper further comprises a driving circuit and a control circuit. Compared with the prior art, the ship transverse-movement windscreen wiper has the advantages that the two motors are started at the same time when the driving circuit is started, the two belt wheel mechanisms drive the windscreen wiper trolleys of the two belt wheel mechanisms respectively to get close to the center of a porthole along the two sides of the porthole under driving of the motors of the two belt wheel mechanisms and then respectively drive the windscreen wiper trolleys of the two belt wheel mechanisms to successively pass the center of the porthole to be dispersed towards the two sides of the porthole, and reciprocating movement is carried out in a same mode. The control circuit is started when the driving circuit is stopped, the two motors are continuously driven by the control circuit, the two windscreen wiper trolleys are accordingly dispersed towards the two sides of the porthole until the sensor is triggered, the two motors are stopped through the control circuit according to triggering signals of the sensor to enable the two windscreen wiper trolleys to be stopped on the two sides of the porthole, it is guaranteed that the view of a driver is not affected, and safe navigation is guaranteed.

Description

technical field [0001] The invention relates to a wiper, in particular to a marine translational wiper. Background technique [0002] The marine wiper refers to the piece structure installed in front of the porthole of the hull, which is composed of a motor, a reducer, a four-bar linkage, a wiper arm shaft, and a wiper blade assembly. Snow and dust. [0003] In order to expand the field of vision of the ship driver and be more conducive to the safety of ship navigation, the size of the front portholes of the ship's cab is getting wider and wider. The length of many portholes is more than 2000mm. On the porthole, the horizontal dimension of the wiper needs to be lengthened to meet the length of the porthole, but the problem is that the speed of the wiper arm cannot keep up due to the increase of the horizontal dimension of the wiper. It affects the crew's vision and is not conducive to the safe navigation of the ship. [0004] In order to overcome the above technical defec...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the above technical defects, the existing method is to arrange the wipers with multiple scraping arms, generally two to three scraping arms. Although this kind of wiper can achieve better wiping effect, once the wiper stops working, there will be some The front scraper arm stops directly in the middle of the porthole, or stops in the driver's field of vision, which affects the crew's vision when driving the ship, which is not only unsightly, but also unfavorable to the safe navigation of the ship
