Marine eletric window wipers

Abstract

A window wiper for a ship is provided to effectively remove interference on a visual field caused by an improper stop position of wipers. A window wiper for a ship comprises a frame(1), pulleys, a belt, an operating rod, reciprocating rods(7b), a wiper arm(8b), and a wiper. The frame is horizontally installed on a hull(B) on the upper or lower side of a window. The pulleys are fixed to both sides of the frame and driven with a single drive motor. The belt is connected to the pulleys to have a caterpillar motion. The operating rod is connected to one side of the belt through a connection bar and moves from side to side. The reciprocating rods are respectively installed on both ends of the operating rod and move from side to side on both sides of the frame. The wiper arm is connected to the reciprocating rods and the wiper is coupled to the end of the wiper arm. One end of the operating rod is fixed to the reciprocating rod while the other end is provided with a connecting piece.

Description

Technical field [0001] The present invention relates to a windshield wiper for a ship which is installed on the upper or lower glass window of a ship and moves left and right to wipe off rain or snow falling on the glass window, and more particularly to a windshield wiper for eliminating the need for windshield wipers when stopped. This causes the phenomenon of obstructing the field of vision. Therefore, the simple structure minimizes the driving load and realizes the control of the stop position of the wiper on the left and right sides of the glass window. Background technique [0002] Generally speaking, windshield wipers are provided on the glass windows of ships to ensure the visibility when it rains or snows without affecting the navigation of the ship. [0003] According to the installation conditions, the above-mentioned ship wiper causes one or a pair of wiper arms to reciprocate left and right at a certain distance along the horizontally long frame on the hull, so as to pa...

AI Technical Summary

Problems solved by technology

[0008] However, in the above-mentioned prior art windshield wiper for ships, since the two reciprocating rods of the windshield wiper are respectively provided with separate levers, and solenoids for separating the separate lever from the two ends of the running lever are respectively installed on both sides of the frame, Therefore, there is a problem that the structure is complex and not easy to install, and the installation cost is also high.

[0009] In addition, each solenoid separates the reciprocating rod from both ends of the running rod by directly moving the separation rod, so the running load acts directly on the solenoid, shortening the life of the solenoid

[0010] In addition, because the separation rod is connected to the running rod by the elastic force of the spring, the connection state of the reciprocating rod and the running rod is very unstable, which easily leads to the separation of the reciprocating rod and the running rod.
