Rotatable Hydrant Protection Device Using Water Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fire hydrant protection systems require a special key or device for access, leading to potential delays in firefighting and vulnerability to sabotage, as they do not automatically allow water flow without manual intervention.
Innovation Solution
A protection system for fire hydrants that includes a nozzle with a rotatable protection device and a bracket assembly, which automatically allows water flow based on water pressure, eliminating the need for a special key and ensuring access without manual disabling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a special key or disabling device is used to protect the fire hydrant, then unauthorized access is prevented, but access time is delayed and the system becomes more vulnerable to sabotage
Solution Approach 1:
The protection device automatically opens when water pressure is applied, eliminating the need for manual intervention with keys or disabling devices. The system serves itself by using the firefighting water pressure to trigger the opening mechanism, thus providing both protection and rapid access without external assistance
Solution Approach 2:
The protection device is pre-configured to respond automatically to water pressure. The bracket assembly and protection device are positioned and configured beforehand so that when water pressure occurs during firefighting, the opening action happens immediately without requiring pre-positioned keys or manual disabling steps
2Ease of operation
If a loose protection device is used that can be removed, then access can be provided, but the device may be lost or not reinstalled, eliminating future protection
Solution Approach 1:
The protection device is merged with the hydrant structure through the bracket assembly that attaches to fixed components of the hydrant. This integration ensures the protection device remains securely attached during removal and reinstallation operations, preventing loss and ensuring proper reattachment for continued protection
Solution Approach 2:
The protection device transitions from a static locked position to a dynamic movable position during operation. The bracket assembly allows the device to be temporarily displaced for access while maintaining connection points that enable secure repositioning, creating a dynamic system that adapts to operational needs while maintaining security
3Reliability
If the protection device requires manual disabling, then security is maintained, but critical time is lost during emergency response
Solution Approach 1:
The system uses the firefighting water pressure itself to trigger the opening mechanism, eliminating the need for manual disabling actions. The protection device automatically responds to the presence of water pressure, providing both security during normal conditions and rapid access during emergencies without human intervention
Solution Approach 2:
The bracket assembly utilizes hydraulic pressure from the firefighting water flow to automatically open the protection device. The water pressure itself becomes the actuating force that moves the protection device from closed to open position, eliminating manual intervention and accelerating response time

AI summary
The protection system protects a fire hydrant. The protection system includes a nozzle, a protection device, and a bracket assembly. The nozzle defines a bore, is in fluid communication with an interior of the fire hydrant, and is adaptable to receive a fire hose. The protection device is carried by the bore of the nozzle for prohibiting access into the interior of the fire hydrant from the exterior. The protection device includes a first position for preventing access into the fire hydrant from the exterior, and a second position wherein water can flow from inside the fire hydrant externally via the nozzle. The bracket assembly is coupled to the protection device for rotating the protection device and carried by the nozzle, wherein the bracket assembly has sufficient rotational travel for enabling the protection device to move from the first position to the second position, depending on the water pressure.
