Sliding Hatch Water-Stop Structure for Wind-and-Rain Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wind-and-rain guard devices for shipping are costly and complex, particularly when dealing with large vessels, and they struggle to prevent wind and rain from seeping through the gap between sliding hatch covers and hatch coamings during loading.
Innovation Solution
A wind-and-rain guard device featuring a water-stop member in a plate shape, held upright by a stand part, which closes the gap between the sliding hatch cover and hatch coaming, along with a seal holding part and a hanger part for suspending the water-stop member, effectively sealing the gap and preventing wind and rain ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a building with an overhanging roof is constructed on the quay to prevent cargo from getting wet, then cargo protection from rainfall is improved, but the cost of installation increases and it becomes difficult to cope with large vessels
Solution Approach 1:
The invention extracts the rain protection function from the fixed building structure and relocates it to a movable lid member that can be positioned only when needed during cargo loading, eliminating the need for permanent expensive infrastructure while maintaining protection effectiveness
Solution Approach 2:
The invention transforms the static overhanging roof structure into a dynamic, movable lid member that can be positioned and repositioned as needed during cargo loading operations, allowing adaptability to different vessel sizes and loading configurations while reducing installation costs
2Object-affected harmful factors
If a film cover is used to cover the hatch with multiple pieces of equipment, then cargo protection from rainfall is improved, but the control becomes complex and expensive, and the shiploader requires extensive modifications
Solution Approach 1:
The invention extracts the rain protection function from the complex film cover system with multiple equipment pieces and integrates it into a simple, single lid member that works with the existing shiploader without requiring extensive modifications
Solution Approach 2:
The lid member is designed to perform multiple functions: it protects cargo from rain, can be positioned at different locations along the hatch opening, and works with various vessel sizes, eliminating the need for complex specialized equipment while providing versatile protection
3Ease of operation
If sliding hatch covers are lifted from the hatch coaming during opening, then hatch cover operation is improved, but a gap is formed between the sliding hatch cover and hatch coaming allowing wind and rain to seep in
Solution Approach 1:
The invention introduces a water-stop member as an intermediary element between the sliding hatch cover and hatch coaming that fills the gap created during operation, preventing wind and rain ingress while allowing the hatch cover to remain operable and lifted from the coaming
