Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dust suppression experimental equipment is limited in studying the atomizing properties and dust suppression effects of individual or multiple nozzles at different space positions, as it lacks the capability for automatic adjustment and change of nozzle positions, restricting its application in simulating real-world dust suppression scenarios.
Innovation Solution
A multi-nozzle combined atomizing dust suppression experimental equipment is developed, featuring a simulated roadway device, water spray-based dust suppression system, and a nozzle position adjustor with electrically-controlled drive systems, allowing for the adjustment of nozzle positions and simulation of various spray parameters, including mist flow forms, nozzle calibers, and space positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing water spray based dust suppression experimental equipment is used, then individual nozzle at fixed position can be studied, but automatic adjustment and change of nozzle space positions cannot be achieved
Solution Approach 1:
The patent implements dynamic position adjustment of nozzles through a positioning mechanism that allows the nozzle assembly to move along guide rails. The positioning mechanism includes adjustment components that enable continuous or discrete position changes, transforming the static fixed-position study into a dynamic multi-position study capability.
Solution Approach 2:
The nozzle assembly is segmented from the fixed structure, allowing independent movement and repositioning. The positioning mechanism is divided into adjustable components that can be independently controlled, enabling flexible configuration of nozzle positions for different experimental scenarios.
2Adaptability or versatility
If multiple nozzles at different space positions are studied, then atomizing properties and dust suppression effects can be comprehensively evaluated, but automatic adjustment of nozzle positions is required which increases device complexity
Solution Approach 1:
The positioning mechanism is designed to enable self-adjustment of nozzle positions through manual or automated control systems. The adjustment components allow the nozzle assembly to be repositioned without requiring complex external intervention, achieving automatic or semi-automatic configuration for different experimental setups.
Solution Approach 2:
The positioning mechanism serves multiple functions: it enables position adjustment, maintains nozzle alignment, and supports different nozzle configurations. This multi-functional design reduces the need for separate adjustment mechanisms for each function, thereby controlling overall device complexity while achieving versatile multi-nozzle study capabilities.
