Hydraulic Bus Battery Fire Lance for Rapid Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire extinguishing methods for electric buses are ineffective due to the weight and size of the vehicles, making it difficult to extinguish fires in electric bus batteries, which are often high-capacity and difficult to access.
Innovation Solution
An electric bus fire extinguishing apparatus using a hydraulic cylinder for loading and unloading, featuring a foldable frame, support stand, and lance for spraying fire-extinguishing water directly into the battery, allowing close contact and rapid fire suppression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a crane is used to lift the electric bus and contain it in a water tank, then fire extinguishing coverage is improved, but the method is difficult to apply due to the weight and size of the electric bus
Solution Approach 1:
The fire extinguishing system is segmented into a portable apparatus that can be independently deployed without requiring crane operations. The apparatus separates the water storage function (in the transporting vehicle) from the delivery function (lance with pump), enabling direct application to the battery without lifting the entire bus.
Solution Approach 2:
The lance acts as an intermediary device that bridges the gap between the water source and the battery. It delivers water directly to the fire source through a targeted pathway, avoiding the need for complete submersion or crane-based positioning.
2Reliability
If a large amount of fire-extinguishing water is sprayed for a long time, then fire suppression effectiveness is improved, but the time required for fire extinguishing increases
Solution Approach 1:
The system employs a hydraulic pump to generate high-pressure water flow through the lance. This pressurized delivery mechanism increases the velocity and penetration force of the water, enabling rapid fire suppression with reduced spray duration compared to low-pressure systems.
Solution Approach 2:
The lance concentrates the water flow into a focused jet that directly targets the battery interior. This localized high-density water application is more effective than diffuse spraying, achieving rapid cooling and fire suppression in a shorter time period.
3Productivity
If the lance sprays high-pressure fire-extinguishing water into the battery, then fire extinguishing speed is improved, but the lance must remain stable during operation
Solution Approach 1:
The support stand is deployed and positioned before the lance operation begins. This preliminary stabilization action ensures the lance maintains its position during high-pressure water delivery, preventing displacement or instability that would compromise the fire extinguishing operation.
Solution Approach 2:
The support stand structure provides counterbalancing forces to resist the recoil and vibration generated by high-pressure water discharge. This counteraction maintains lance stability despite the dynamic forces involved in rapid fire suppression.
