Description

Exclusive indoor fire hydrant for each apartment house}

The present invention relates to a dedicated indoor fire hydrant for each household in an apartment complex. More specifically, the indoor fire hydrant connects fire water to the water supply pipe of each household, uses the water supplied along the water supply pipe, and uses water supplied along the water supply pipe to prevent blockages in the pipe or fire water. If the amount of water supplied through the water supply pipe is insufficient due to factors such as insufficient supply, this is immediately recognized and fire extinguishing water is continuously supplied from the fire extinguishing water tank provided on the roof of the building, thereby preventing fire suppression failure. This is about a dedicated indoor fire hydrant for each household in an apartment complex that can be prevented.

Typically, an indoor fire hydrant is one of the firefighting facilities installed to extinguish fires occurring inside a building. These indoor fire hydrants are mainly located inside buildings and are installed in common areas such as basements, hallways, and elevator vestibules.

The indoor fire hydrant stores fire extinguishing agents and is equipped with fire extinguishing equipment to enable a quick and active response in the event of a fire. For example, an indoor fire hydrant includes a fire extinguishing tank, fire hose, and fire extinguishing nozzle.

Typically, indoor fire hydrants are installed in common areas of apartments. Conventionally, instead of installing an indoor fire hydrant directly inside the household, there are cases where a portable fire extinguisher such as a foam fire extinguisher is installed inside the household. These portable fire extinguishers are relatively small in size, easy to install, and are effective in fire prevention and initial suppression. However, these fire extinguishers only allow people living indoors in each household to extinguish small-scale fires due to limitations in the capacity of the fire extinguishing agent.

Previously, when a fire broke out in each unit of an apartment, residents had to disengage the fire hose from the indoor fire hydrant installed in the common area of the apartment due to the lack of knowledge on how to use the indoor fire hydrant, and in the case of women or the elderly, so that the corresponding household had to release the fire hose. There is a realistic problem of extinguishing a fire. In addition, there is a problem in that it is impossible to initially extinguish a fire because the time it takes to supply water to an indoor fire hydrant installed in a common area and to move into a household is long.

If the fire ignites when no occupants are present in the household, it is impossible to initially extinguish the fire. Therefore, the indoor fire hydrant according to the present invention has a fire monitoring function, immediately transmits the fire situation to the occupants in real time, and immediately remotely adjusts the indoor fire hydrant to start the fire. It is true that there is no firefighting technology to extinguish the fire.

When the occurrence of the fire is detected, the controller unwinds the fire hose using the winder and simultaneously moves the fire hose using the mover to force the nozzle to the outside of the main body through the draw-out hole. Withdraw,
The wall is provided with a receiving groove and a door that opens and closes the receiving groove,
The main body is disposed in the receiving groove,
The door is installed on the wall to open and close the receiving groove through sliding movement by driving a linear motor,
When the occurrence of a fire is detected, the controller moves the door using the linear motor to open the receiving groove to expose the main body to the room,
The connection between the connector and the fire water supply pipe is connected through a connecting tube having elasticity and heat resistance, and the connecting tube is formed in a corrugated shape and can be stretched,
A support frame supporting the edge of the indoor fire hydrant is disposed in the receiving groove,
Elastic springs are further installed at a plurality of positions on the inner wall of the receiving groove and connected to a plurality of positions around the outer circumference of the support frame to elastically support the support frame,
A cooling coil is embedded inside the main body, and the cooling coil receives current from a current provider and is cooled to a certain cooling temperature.
When the fire is detected, the controller cools the cooling coil using the current provider,
A nozzle elevator is installed on the door,
The nozzle elevator has a lifting cylinder having a lifting shaft that is raised and lowered under control of the controller, and a grip member installed at a lower end of the lifting shaft to grip the nozzle,
The lifting cylinder is installed in the main body so as to be located at the upper part of the drawing hole,
A proximity sensor is installed in the drawing hole to detect the location of the nozzle and transmit it to the controller,
The controller is,
When the position of the nozzle is detected, the nozzle drawn out through the draw hole is gripped using the grip member,
Lowering the lifting shaft of the lifting cylinder to place the nozzle on the ground,
After the nozzle is positioned on the ground, the gripping state of the nozzle is released using the grip member, and the lifting shaft is raised to move the grip member to the standby position,
The controller is electrically connected to a camera module that acquires an image of the room, processes the acquired image to calculate a temperature distribution image, and selects an ignition location where the fire occurred from the temperature distribution image. ,
The nozzle includes a position sensor that measures position information and transmits the measured position information to the controller;
The nozzle has a moving device,
The moving device includes moving rollers and a rotation motor that rotates the moving rollers,
The controller controls the moving roller to rotate along the ground using the rotation motor to move the nozzle to the ignition position,
A fire water supply tank in which auxiliary fire water is stored is installed on the roof of the apartment building,
The fire water supply tank and the fire water supply pipe are connected through an auxiliary fire water supply pipe,
An auxiliary supply pump is installed in the auxiliary fire water supply pipe,
A second flow rate sensor is installed in the branch pipe to measure a second flow rate of fire water flowing through the branch pipe and transmits it to the controller,
The controller is,
When the measured second flow rate is not measured while the first on/off valve is open,
An indoor fire hydrant exclusively for each apartment unit, characterized in that the auxiliary supply pump is driven to supply fire water from the fire water supply tank to the fire water supply pipe through the auxiliary fire water supply pipe.
According to clause 1,
The fire water supply tank is disposed inside the waterproofing device,
The fire water supply tank is,
Equipped with a pressure sensor that measures the internal pressure of the fire water supply tank and transmits it to the controller,
The waterproof device is,
a device body forming an internal space where the fire water supply tank is disposed;
It includes waterproof wall units installed to protrude from the inner periphery of the device body so as to follow the circumference of the fire water supply tank,
The controller is,
When the pressure measured through the pressure sensor reaches a preset leakage pressure, the waterproof wall units are driven to elastically adhere to the perimeter of the fire water supply tank,
Each of the water barrier units,
A cylinder having a protruding shaft, and a waterproof member installed on the shaft and made of an elastic material,
As the shaft protrudes, the waterproof member is in close contact with the circumference of the fire water supply tank.
