The present invention provides a mounting base for a marine wiper, which relates to the field of marine wipers. The mounting base of the marine wiper comprises a first base assembly and a second base assembly arranged at intervals, wherein the structure of the first base assembly is the same as that of the second base assembly, and the first base assembly comprises a first angle steel and a second angle steel; The first angle steel comprises a fixedly connected first horizontal section and a first vertical section, wherein the first vertical section is perpendicular to the first horizontal section, and the first horizontal section is used for fixing on the outer board of the ship; The second angle steel comprises a fixedly connected second horizontal section and a second vertical section, wherein the second vertical section is perpendicular to the second horizontal section, the second horizontal section is provided with a long slot, and the length direction of the long slot extends along the width direction of the second horizontal section; The first vertical section is fitted with the second vertical section, and the first base assembly also comprises a fastener for fixedly connecting between the first vertical section and the second vertical section, so as to fixedly connect the first angle steel and the second angle steel; The end of the first angle steel is provided with a first reinforcing rib, and the second angle steel is provided with a second reinforcing rib, wherein the first reinforcing rib and the second reinforcing rib are connected with a threaded adjusting member, the length direction of the threaded adjusting member extends parallel to the length direction of the first angle steel, so as to adjust the relative positions of the first angle steel and the second angle steel after the fastener is loosened, so as to meet the need for adjusting the position of the wiper during installation.
This document is Chinese invention patent CN 113771797 B, "一种船用雨刮器的安装基座" (A mounting base for a marine wiper), applied for on 2021-08-27 and granted with publication on 2023-05-30. The patentee is 中船黄埔文冲船舶有限公司 (Zhongchuan Huangpu Wenchong Shipbuilding Co., Ltd.), Guangzhou, with inventors including 符城彬, 梁赞, 魏巍 and others.
The patented mounting base consists of two identically structured base assemblies spaced apart, each made of a first angle steel fixed to the hull shell plate and a second angle steel with a long slot for mounting the wiper guide rail. The two angle steels are clamped together by fastener bolts through slotted adjustment holes, and a threaded adjuster connected between reinforcing ribs on both angle steels allows the second angle steel to be shifted along the first angle steel once the fasteners are loosened. This permits on-site adjustment of the wiper position when hull structural deformation or installation errors would otherwise prevent correct mounting, avoiding rework costs. The claims further cover a handwheel on the adjuster, matching friction ridges and grooves on the clamped faces, and attachment of the wiper guide rail by a bolt through its connection hole and the long slot. This manual is written in Chinese.
| Base configuration | Two identically structured base assemblies arranged at an interval |
|---|---|
| Position adjustment | Threaded adjuster between reinforcing ribs shifts the second angle steel after fasteners are loosened |
| Fastening | Fastener bolts through slotted adjustment holes with nuts |
| Manual adjustment | Handwheel connected non-rotatably to the threaded adjuster |
| Anti-slip clamping | Parallel ribs with matching grooves on the clamped vertical faces |
| Guide rail mounting | Wiper guide rail fixed by a bolt through its connection hole and the long slot |
It allows the wiper installation position to be adjusted on site when hull structural deformation or installation errors prevent the base from being mounted in place, avoiding rework that deforms the hull shell plate and adds cost and time.
The guide rail has a connection hole at its end that is bolted together with the long slot in the second angle steel using a fixing bolt, so the rail can be shifted left or right along the slot.
