Protection structure of sampling tube of tank truck
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The sampling tube of a tank truck is prone to damage and leakage due to unexpected falls during connection, posing risks to human safety and the environment.
Innovation Solution
A positioning and protecting base is provided around the sampling tube's outer circumference, with the sampling output port extending through a through hole to project partly outside, enhancing stiffness and strength while maintaining connection readiness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sampling tube is clamped between the receiving pipe and supply pipe using bolts, then the sampling tube can be securely fixed for connection, but the sampling output port located on the top side is vulnerable to impact and damage during the connection process
Solution Approach 1:
A positioning and protecting base is introduced as an intermediary component between the sampling tube and the clamping structure. This base extends around the outer circumference of the sampling tube and provides a protective enclosure that shields the sampling output port from direct impact during the bolting operation, while still allowing the bolts to penetrate through the base to secure the sampling tube firmly between the receiving pipe and supply pipe.
2Ease of operation
If the sampling output port is located on the top side of the sampling tube for easy connection, then connection readiness is improved, but the port becomes more exposed and susceptible to damage during the clamping operation
Solution Approach 1:
The positioning and protecting base provides localized protection specifically around the sampling output port area while maintaining the top-side location of the port for ease of connection. The base structure is designed to extend around the outer circumference of the sampling tube, creating a protective enclosure at the vulnerable top region without interfering with the connection operation, thus achieving both connection readiness and impact resistance.
3Reliability
If a protective structure is added around the sampling tube to prevent impact damage, then the sampling output port is protected from damage, but the device complexity increases
Solution Approach 1:
The positioning and protecting base serves multiple functions simultaneously: it protects the sampling output port from impact damage, provides positioning support during the clamping operation, and acts as a structural element that can be integrated with the existing bolting system. By combining these functions into a single component, the design minimizes the increase in device complexity while achieving comprehensive protection.

AI summary
A protection structure of a sampling tube of a tank truck is provided. A positioning and protecting base is provided around an outer circumference of the sampling tube. The sampling tube includes a sampling output port for connection with a sampling output hose. The positioning and protecting base includes a through hole. The sampling output port extends through the through hole to partly project outside of the positioning and protecting base. With such an arrangement, the stiffness and strength of the entire sampling output port are enhanced for resisting impact and hit, and readiness of connection between the sampling output port and a sampling output hose is not negatively affected to thereby improve usage performance of the sampling tube.
