Core Drill Water Collector Preventing Machine Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current core drilling units lack effective solutions to collect and divert spent cooling water and drill cuttings, which can lead to water damage and operational issues during ceiling drilling, with existing methods like plastic film coverage being unreliable and messy.
Innovation Solution
A water collecting device is positioned below the core drill, featuring a vessel with a wider diameter than the drill, equipped with a draining hole and duct for suction pump connection, and additional features like a detachable sleeve and conical cover plate to prevent water from reaching the drilling machine, ensuring efficient collection and drainage of spent water and cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plastic film is used to cover the drilling machine, then the machine is protected from water damage, but the work environment becomes messy and water flows onto the floor
Solution Approach 1:
The harmful element (spent water with cuttings) is extracted from the system by directing it into a separate collection container positioned below the drill, preventing it from contacting the drilling machine while avoiding the need for plastic film coverage
Solution Approach 2:
A collection container acts as an intermediary element between the drill and the floor, intercepting spent water and cuttings before they can reach the drilling machine or the floor, thus solving both protection and cleanliness requirements
2Device complexity
If no water collection device is used, then the device structure remains simple, but water flows onto the machine causing short-circuiting and damage
Solution Approach 1:
The protection system is segmented into a separate collection container positioned below the drill, which intercepts water before it reaches the machine. This modular approach provides effective protection while maintaining relative structural simplicity
Solution Approach 2:
A collection container serves as an intermediary device between the drill and the drilling machine, capturing spent water and preventing it from causing damage to the machine's electrical components
3Reliability
If plastic film covering is used, then the drilling machine is protected from water, but the spent water and cuttings flow onto the floor requiring additional removal effort
Solution Approach 1:
The collection container extracts and contains spent water and cuttings at the source (below the drill), preventing these materials from being deposited on the floor and eliminating the need for additional cleanup operations
Solution Approach 2:
The collection container acts as an intermediary that intercepts the flow of spent water and cuttings, directing them into a contained space rather than allowing them to reach the floor, thus solving both protection and waste management requirements
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The water collecting device effectively captures and removes spent cooling water and drill cuttings, preventing machine damage and maintaining a cleaner work environment by ensuring all water flows into the collector, reducing the risk of splashing and entry into the machine's internal components.
Implementation Method 1
a draining hole in the bottom of the vessel, through which there is arranged a draining duct, that can be connected to a suction pump in order to effectively remove the polluted water that is gradually gathering in the water collector
Implementation Method 2
the spent cooling water with the drill cuttings from the core drill flows down onto the water collector
