Hydraulic Water Drill Lance for Stacked Container Fire Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for extinguishing fires in containers are labor-intensive, dangerous for workers, and inefficient, especially when fires occur in stacked containers at varying heights, due to the need for manual perforation and exposure to heat and smoke.
Innovation Solution
A water drill lance that automatically forms a fire-extinguishing hole in a container door using hydraulic pressure and adjusts its vertical height, comprising a clamp body, lock hook assembly, drill module, and lance support for safe and rapid fire extinguishment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a worker manually perforates the container door using a hammer, then the fire can be extinguished by injecting water through the hole, but a lot of time and labor are required and the worker is exposed to fire and explosion risks
Solution Approach 1:
The patent replaces the manual mechanical hammering process with a hydraulic drill system. The drill module uses hydraulic pressure to rotate a drill bit that automatically perforates the container door, eliminating the need for workers to manually hammer and exposing them to fire hazards. The hydraulic system provides controlled, consistent drilling force while keeping workers at a safe distance.
Solution Approach 2:
The drill module is designed to automatically perforate the container door without requiring manual intervention during the drilling process. The hydraulic system self-regulates the drilling operation, and the lance automatically positions itself to inject water through the perforated hole, reducing the need for continuous worker involvement and exposure to danger.
2Adaptability or versatility
If a worker climbs a ladder to reach high-positioned containers, then the container door can be perforated, but the worker is exposed to various risks including falls and fire exposure
Solution Approach 1:
The lance is equipped with a height adjustment mechanism that allows it to dynamically adapt to different container heights. The lance support structure can be extended or repositioned vertically, enabling the drill module to reach container doors at various elevations without requiring workers to climb ladders. This dynamic adjustment capability maintains worker safety while providing versatility for different stacking configurations.
3Productivity
If conventional manual methods are used to perforate the container door, then the process can be completed, but it is very difficult and dangerous for the worker to directly inject the lance in situations with enormous heat emission
Solution Approach 1:
The patent introduces the drill module and lance assembly as an intermediary system between the worker and the fire. The worker operates the hydraulic system from a safe distance, and the automated drill-lance assembly performs the dangerous tasks of perforating the door and injecting water into the hot container interior. This intermediary mechanism protects workers from direct exposure to enormous heat while maintaining effective fire suppression capability.
4Adaptability or versatility
If multiple stacked containers are on fire, then all containers need to be addressed, but workers would need to repeatedly mount and climb ladders for each container
Solution Approach 1:
The height-adjustable lance can be rapidly repositioned between different container heights without requiring workers to dismount and remount ladders. The hydraulic or mechanical adjustment system allows quick vertical movement of the drill module to match the height of different stacked containers, significantly reducing the time lost to repeated ladder operations while handling multiple containers on fire.

AI summary
The present invention relates to a water drill lance for extinguishing a fire in a container, which, when a fire occurs in a container, can extinguish the fire by automatically drilling a fire-extinguishing hole through a container door by means of a hydraulic pressure and then spraying water into the container, and can quickly extinguish a fire regardless of the height of containers stacked in multiple layers through vertical height adjustment.
