Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing track-type pipeline robots are too large to detect geological parameters effectively in loess holes with smaller diameters, such as 100-150 mm, due to their larger radial size, which limits their applicability in loess geological information detection.
Innovation Solution
An in-situ detection robot for loess geological information is designed with a compact tensioning system, including an active tensioning mechanism with a tensioning motor, driving camshaft, and driven cam groups, and an auxiliary tensioning system with elastic sleeves and an odometer wheel, allowing the robot to adapt to aperture changes and travel within smaller loess holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If track-type pipeline robot is used to improve obstacle-crossing ability and trafficability performance, then the robot can handle loess hole defects, but the robot's radial size becomes too large for small diameter holes (100-150 mm)
Solution Approach 1:
The robot body is divided into multiple modular sections that can be independently adjusted. The housing includes adjustable components that allow the robot to segment and reconfigure its structure to fit within the limited radial space of small diameter loess holes while maintaining track-type mobility capabilities.
Solution Approach 2:
The robot employs dynamic adjustment mechanisms that allow real-time modification of its radial dimensions. The housing and track system can dynamically compress or expand to adapt to varying hole diameters, enabling the robot to maintain obstacle-crossing ability while fitting into small 100-150 mm diameter loess holes.
2Measurement precision
If manual soil sampling with laboratory testing is used to obtain soil mechanical properties, then test parameters can be measured, but the original structure of the soil is destroyed
Solution Approach 1:
The robot carries integrated detection instruments that perform measurements in-situ within the loess hole. The system serves itself by collecting soil mechanical property data directly at the measurement location without requiring external laboratory analysis, thereby preserving the original soil structure while obtaining precise measurement data.
Solution Approach 2:
The patent replaces traditional mechanical soil sampling and laboratory testing with non-contact or minimal-contact detection instruments. These instruments use physical fields (such as electromagnetic, acoustic, or optical fields) to measure soil mechanical properties without mechanically disturbing or destroying the soil's original structure.
