Abstract
Description
Technical area:
[0001] The present invention relates to a component intended to prevent water damage during firefighting exercises, in particular in foggy rooms or during fire simulations in buildings and outdoors.
[0002] State of the art: During fire drills in industrial facilities, craft businesses, and public and private buildings, accidental water discharge can cause significant water damage. This damage occurs particularly when firefighters' visibility is severely restricted by artificially generated fog. The fog is usually created by special fog generators designed to simulate the drill situation as realistically as possible, thus optimally preparing emergency personnel for an emergency.
[0003] In such realistic training scenarios, visibility is severely reduced, making the work of firefighters considerably more difficult. In the hectic and stressful environment of an exercise, it's easy for water to be accidentally released, resulting in extensive water damage. This particularly affects sensitive technical equipment, machinery, and systems located in training rooms. Such property damage can result in high costs and significantly disrupt ongoing operations in industrial facilities or public buildings.
[0004] The use of real water to simulate firefighting operations therefore carries a high risk. Companies and operators of public buildings face the challenge of effectively training their emergency personnel without risking property damage. This poses a significant risk for these facilities, as training under realistic conditions is nevertheless essential for preparing for actual fire incidents.
[0005] This is where the dry nozzle coupling (DUS) comes in. The DUS is an innovative solution developed to prevent the accidental discharge of water during fire simulations or when searching for people in smoke-filled buildings. The central element of the DUS is a special coupling piece that is connected between the nozzle and the water-carrying hose. This component ensures that no water can escape, even when the hose is connected and under realistic operating conditions.
[0006] Overall, the dry nozzle coupling offers an innovative and practical solution to the challenges of fire drills. It enables effective training of emergency personnel without the risk of water damage, thus contributing to the safety and efficiency of fire drills.
[0007] Object of the invention: The object of the present invention is to provide a component which prevents water damage during fire brigade exercises without impairing the realistic operational image. Description of the invention:
[0008] The dry nozzle coupling (TSK) consists of two standardized hose couplings according to DIN 14333-1. Between these couplings is a water retention disc, supported by a specially manufactured gasket to ensure complete sealing and compactness of the system. To secure the nozzle during training, an additional locking mechanism is integrated, preventing accidental release. This is necessary because uncoupling is possible with pressureless Storz couplings.
[0009] The entire component is made of aluminum, ensuring high robustness and durability. The neon-colored marking ensures that the component is immediately recognizable as a training device and is not accidentally used in real-life situations. Advantages of the invention:
[0010] Reduction of property damage: The dry-jet nozzle coupling (DJC) effectively prevents water discharge. This protects sensitive equipment and systems from water damage, which could otherwise result in high repair costs and disrupt operations.
[0011] Cost savings: Preventing water damage not only reduces the cost of repairs and replacement parts, but also the downtime costs that could result from damaged equipment or production downtime.
[0012] Improved safety: Preventing water damage also increases safety in exercise environments. Electronic devices and machinery that could be damaged by water pose a potential risk to exercise participants.
[0013] Environmental protection: The economical use of water is another advantage of the TSK. Water resources are conserved during exercises, which makes sense both ecologically and economically. Realistic simulation of stiffness and weight of the fire hose
[0014] A key aspect of firefighting exercises is the realistic replication of operational conditions. This includes not only the environment and scenarios, but also the physical properties of the equipment used.
[0015] Authentic handling: The dry nozzle coupling enables a realistic simulation of the stiffness and weight of the fire hose. Even when no water is flowing, the nozzle remains connected to the hose, making handling realistic. This allows firefighters to train under realistic conditions and become familiar with real-life operational conditions.
[0016] Muscle memory and body control: Training with a hose that has the same weight and stiffness as the one used in a real-life situation helps firefighters develop muscle memory. This means that the movements and maneuvers they perform during the exercise will be automatic and precise when they are in a real-life emergency situation.
[0017] Operational strategies: The realistic simulation allows firefighters to develop and test effective operational strategies. For example, they can practice how best to maneuver the hose through tight or constricted spaces or how to hold it in different positions to work efficiently and safely.
[0018] Teamwork and coordination: The physical demands of a realistically simulated hose promote teamwork and coordination. Firefighters learn how to support each other and optimally distribute the load to avoid fatigue and increase efficiency. Psychological preparation: The realistic weight and stiffness of the hose help firefighters mentally prepare for the challenges of a real-life incident. They can better empathize with the situation and are therefore better prepared for an emergency.
[0019] Overall, the dry nozzle coupling (DTP) significantly contributes to the safety and efficiency of fire drills by preventing water damage and realistically simulating the stiffness and weight of the fire hose. This leads to better preparation of emergency responders while minimizing the risks and costs associated with traditional training methods.
