Auxiliary Device Control for Core Drilling Rig Water Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for controlling water pumps in core drilling rigs require manual switching, leading to inefficient drilling operations and unnecessary water consumption, causing interruptions and site contamination.
Innovation Solution
An automatic control method that switches the water pump on or off based on the operating state of the core drilling device, using status information transmitted between the main tool device and the water management system, allowing for efficient resource use and coordination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual switching of the water pump is used, then the system operation is simple to control, but drilling efficiency decreases due to interruptions and water is wasted during switching time
Solution Approach 1:
The water management system automatically monitors the operating state of the core drilling device and controls the water pump accordingly, eliminating the need for manual intervention. The system serves itself by detecting when water is needed and when the pump should be stopped, thereby maintaining drilling efficiency without sacrificing operational simplicity.
Solution Approach 2:
The system implements feedback control by continuously monitoring the operating state of the core drilling device and using this information to automatically adjust the water pump operation. Status information from the main tool is transmitted to the auxiliary device, creating a closed-loop control system that optimizes water supply based on actual drilling needs.
2Ease of operation
If manual switching of the water pump is used, then control flexibility is maintained, but unnecessary water is supplied causing contamination and resource waste
Solution Approach 1:
The water management system automatically determines when water supply is needed based on the core drilling device's operating state, eliminating unnecessary water consumption. The system monitors actual drilling requirements and adjusts pump operation accordingly, preventing water waste while maintaining appropriate control flexibility through automated decision-making.
Solution Approach 2:
The system prepares to activate the water pump in advance when the core drilling device begins operation, ensuring water is available when needed without causing unnecessary supply during idle periods. This preliminary action based on detected operating states prevents both water waste and contamination.
3Reliability
If the water pump remains on during idle core bit operation, then cooling is maintained, but water is wasted and site contamination occurs
Solution Approach 1:
The system uses feedback from the core drilling device's operating state to control water pump operation. When the core bit is idle or not under load, the system detects this state and automatically stops water supply, preventing water waste and contamination while maintaining cooling reliability during actual drilling operations.
Solution Approach 2:
The water pump operation is made dynamic rather than static, automatically adjusting its state based on real-time detection of the core drilling device's operating conditions. The system transitions between active and inactive states according to actual drilling needs, optimizing both cooling reliability and water conservation.

AI summary
The present invention relates to a method for controlling the operation of an auxiliary device in a working system which comprises at least one main tool device and the auxiliary device. The operating state of the main tool device is determined and transmitted to the auxiliary device in the form of a status information. The auxiliary device can then preferably be automatically controlled, i.e. for example switched on or off, as a function of the operating state of the main tool device. The communication between the main tool device and the auxiliary device is carried out using a communication link.
