Gate Board Tightening Device for Floodgates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional floodgate devices require multiple threaded rods to achieve horizontal compression of gate boards, leading to inefficiencies and potential damage due to uneven force distribution and point contact, which is problematic in emergency situations and under high water pressure.
Innovation Solution
A gate board tightening device with a drive bar, retention plate, first coupling seat, and second coupling seat that allows for in-situ rotation of the drive bar to push all gate boards against a water-resistant strip, providing uniform force and reducing the risk of damage through linear contact along the entire length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple threaded rods are used to apply horizontal compression to gate boards, then the gate boards can be secured between main rails, but the operation time is extended and the risk of part damage increases due to point contact and uneven force distribution
Solution Approach 1:
Multiple threaded rods are merged into a single drive bar that can simultaneously apply compression force to all gate boards through one operational action, reducing operation time while maintaining sealing reliability through unified force application
Solution Approach 2:
The drive bar is designed with multiple engagement points along its length that can simultaneously engage with multiple gate boards, allowing distributed force application that prevents localized overload and part damage while maintaining operational efficiency
2Force
If threaded rods are used to compress gate boards, then horizontal compression is achieved, but the point contact between threaded rods and pressing members causes excessive force concentration and part damage under high water pressure
Solution Approach 1:
The contact interface is transformed from point contact (zero-dimensional) to line contact (one-dimensional) by designing the drive bar to engage with gate boards along its entire length, distributing compression force continuously and preventing excessive stress concentration that would damage parts under high water pressure
Solution Approach 2:
Different sections of the drive bar are designed with specific engagement characteristics optimized for local force distribution, ensuring uniform compression across all gate boards while preventing localized overload through tailored contact geometry at each engagement point
3Force
If multiple threaded rods operate independently to compress gate boards, then horizontal compression is applied, but force distribution becomes uneven leading to insufficient compression and potential damage
Solution Approach 1:
Multiple independent threaded rods are merged into a single drive bar mechanism that applies compression force through one unified operational action, ensuring synchronized and uniform force distribution across all gate boards while eliminating the coordination issues and uneven compression that arise from independent rod operations

Function Achieved in This Case
This solution enables efficient and uniform sealing between gate boards and main rails, reducing the risk of damage and ensuring consistent force application, even under high water pressure, while allowing for quick and efficient operation and dismounting of the gate boards.
Implementation Method 1
the drive bar (3) rotates in-situ... the retention plate (4) rotates or swings so that the retention plate pushes and presses all the gate boards (82) toward and against the water-resistant strip (817)

AI summary
A gate board tightening device (2) is mountable in a main rail (81) of floodgate device (8) and includes a drive bar (3), a retention plate (4), and a first coupling seat (5) and a second coupling seat (6). The drive bar (3) has two ends respectively provided with a first connection terminal (31) and a second connection terminal (32). The first connection terminal (31) is coupled with the first coupling seat (5) and the second connection terminal (32) is coupled with the second coupling seat (6). The retention plate (4) is inserted into a tubular member (814) formed in the main rail (81) of the floodgate device (8) with the first coupling seat (5) mounted at one end of the main rail (81) of the floodgate device (8) and the second coupling seat (6) mounted at an opposite end of the main rail (81) of the floodgate device (8). When gate boards (82) of the floodgate device (8) are sequentially disposed in the coupling channel (811) of the main rail (81), an operation member (A) is inserted into a hole (312) formed in the first connection terminal (31) of the drive bar (3) and the operation member (A) is wrenched to cause the drive bar (3) to rotate in site for driving the retention plate (4) to horizontally push the gate boards (82) so that a powerful tight engagement is established between the gate boards (82) and a water-resistant strip (817) arranged in the main rail (81) of the floodgate device (8).
