Hinged Panel Control Gate for Overshot and Undershot Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control gates for channels and ponds lack the ability to efficiently manage both overshot and undershot movements of liquids, limiting their flexibility and functionality in flow control applications.
Innovation Solution
A control gate system comprising hingedly connected panels with lifting mechanisms, including cable drives and rollers, allowing for both overshot and undershot positions, enabling flexible operation and integration with automated laboratory systems for water quality testing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a control gate is designed to provide both overshot and undershot positions, then the versatility and adaptability of the gate system is improved, but the device complexity increases due to the need for multiple lifting mechanisms and hinged panels
Solution Approach 1:
The gate is divided into multiple panels (first panel, second panel, third panel) that can be independently positioned. Each panel can be raised or lowered separately to achieve different flow control configurations (overshot, undershot, or combinations), allowing a single gate structure to perform multiple functions that would traditionally require separate gates.
Solution Approach 2:
The control gate system is designed to provide multiple flow control modes (overshot position, undershot position, and combinations) using a single integrated gate structure. The lifting mechanisms enable the same gate to adapt to different operational requirements, eliminating the need for separate overshot and undershot gates.
2Adaptability or versatility
If multiple lifting means are added to enable both overshot and undershot operations, then the functionality of the control gate is improved, but the ease of operation deteriorates due to the increased number of control mechanisms
Solution Approach 1:
The lifting mechanisms for different panels are integrated into a coordinated system where the first lifting means raises/lower the first panel for overshot operation, the second lifting means raises/lower the second panel for undershot operation, and the third lifting means raises/lower the third panel. This coordinated control allows multiple functions to be managed through an integrated system rather than separate independent mechanisms.

AI summary
A control gate for a channel or pond adapted to be installed across a channel for liquids. The control gate includes: at least two panels hingedly connected together, the panels having opposing sides in sealing engagement with side walls of the channel, a lowermost panel being in sealing engagement with the floor of the channel. The panels are substantially vertically aligned in a fully closed position of the control gate. At least one first lifting element is connected to the top of an uppermost panel and is adapted to lower and raise the uppermost panel relative to its hinged connection in a concertina manner to provide an overshot position for the control gate. At least one second lifting element is connected to the bottom of the lowermost panel to raise and lower the lowermost panel from the floor of the channel to provide an undershot position for the control gate.
