DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small firefighting system in which a manhole provided with a water storage tank is buried in the soil by utilizing an open space such as a city or a densely populated area of a house, and a space inside the manhole. A storage device and a storage method for a fire pump pump case in which a pump case or a fire extinguisher is freely inserted and removed.

[0002]

2. Description of the Related Art A conventional fire pump has its body mounted on a four-wheeled vehicle and is dispatched to a fire site when a fire occurs. At the fire site, a hose is connected to a fire hydrant to spray water from a fire-extinguishing nozzle.

[0003]

In the conventional firefighting activities, a plurality of firefighting pumps and personnel are arranged in a certain place, dispatched at once according to a fire report, and dispatched from the fire department depending on the size of the fire. Although they are informed to take a position, there is a problem that due to traffic congestion or a change in weather, the fire spreads and spreads by the time the fire department arrives, and the damage is further increased.

Accordingly, the present invention considers that it is most appropriate to extinguish a fire at least in a short time at the same time as the occurrence of a fire, and to provide a manhole having a water tank in the soil of a city or a densely populated area of a house or a road surface of a building or open space. Provide a lid on the ground so that it does not interfere with walking, insert the inner cylinder into the manhole, and mainly store the small fire pump case in the inner cylinder. In the event of a fire, conduct immediate training so that neighbors can immediately extinguish the fire, and at the same time as the fire starts, easily remove the small fire pump case from the inside of the inner cylinder and move it to a predetermined place. It aims to extinguish or extinguish a fire quickly by taking out a small fire pump from its case.

Further, the fire pump pump case is made of a material having corrosion resistance and is formed so as not to cause damage to the fire pump, and provides a storage method that allows easy access to the inner cylinder in the manhole. It is intended to be.

[0006]

Means for Solving the Problems In order to achieve the above-mentioned object, in a storage device for a fire pump pump case according to the present invention,
The bottom of the manhole having the water storage tank is bent inward to form a circular orbit.

On the track, a ring-shaped box containing a ball bearing as a rotating mechanism is covered with a lid so as to cover freely so that it can rotate freely, and an inner cylinder is placed on the cover, and an inner cylinder is mounted. The outlet can be arbitrarily selected by rotating the upper end of the inner cylinder by its own gravity. It is also effective to interpose a rubber cushion material between the lid and the lower end surface of the inner cylinder to stop the slip.

In the inner cylinder, an arc-shaped peripheral portion of the receiving plate facing the left and right at a predetermined interval is mounted on a part of the rotating mechanism so as to rotate with the rotation of the inner cylinder.

It is effective if wheels are attached to the lower end surface of the inner cylinder so that they roll along the trajectory of the manhole.

[0010] Further, in order to plant a plurality of support rods in the inner cylinder, a fixture is attached to an upper portion of the inner wall surface of the inner cylinder, the upper end of the support rod is attached to the fixture, and the support rod is suspended and inserted into the receiving plate. The spring is wound around this support rod, and the lower end of the spring is attached to the receiving plate.

The receiving plate is lifted upward by the repelling force of the firing, and at the same time, the fire pump inlet case on the receiving plate is placed on a rail inclined toward the outlet direction above the bottom of the inner wall surface of the inner cylinder. The wheels supported on the left and right sides of the input case can be taken out along the way.

When the fire pump pump case is taken out, the receiving plate keeps its raised state due to the pulling force of the fire.
A small fire pump that always has a water suction pipe inserted into a water storage tank is taken out of the case and a hose is attached to perform fire fighting.

In order to prevent the fire pump case from automatically popping out, it is effective to provide a stopper inward at an arbitrary position on the upper end surface of the inner cylinder.

A track is formed by bending the bottom of the manhole inward to form a track, a polygonal inner cylinder is housed in the manhole and supported on the track, and a fixture is attached above the even-angled portion of the polygonal inner cylinder. The upper end of the support rod around which the spring is wound is attached to the fixture, and the lower end of the spring is fixedly attached to the support plate by hanging it down on a support plate provided slightly above the upper surface of the track. A receiving plate attached to the upper surface of the support plate is erected between the support plates. And, as described above, the wheels provided on the fire pump inlet case move to the upper entrance and exit along the rail protruding from the inner wall surface of the inner cylinder with the pulling force of the spring, and the guide wheels attached to the upper end in the inner cylinder The fire pump case can be easily removed.

The inner cylinder is housed in the manhole, and as a storage method of the fire pump pump case in the inner cylinder, the inner cylinder is used as a storage room, a lid is provided on the upper surface of the manhole, and the bottom is bent inward to form the track. A support rod is formed between the raceway and the lower end surface of the inner cylinder with or without a rotating mechanism, and a fixing tool is provided above the inner wall surface of the inner cylinder, and a spring is wound around the fixing tool. The lower end of the spring is connected to the receiving plate, and the rail is projecting from the bottom of the inner wall surface of the inner cylinder in a direction inclined upward and downward from the bottom of the inner cylinder in relation to the accumulating force of the firing. This is a method for storing a fire pump pump case in which wheels provided on the left and right side surfaces of the fire pump pump case placed on the inner surface of the fire pump pump case are allowed to slide in and out of the inner cylinder.

According to the present invention, a manhole having a water storage tank is provided in an open space such as an urban area, a densely populated area of a house, a park and the like, and a fire pump case is accommodated in this manhole. In addition, since the fire extinguishing operation can be performed before the arrival of the fire truck without deteriorating the function of the internal fire pump, there is an effect that a large fire can be prevented. In addition, there is an effect that the water tanks scattered in the buildings and various places can be used.

In the inner cylinder, a supporting rod supported by a fixing tool, a spring wound around the supporting rod, a receiving plate attached to the lower end of the spring, and a rail provided on the inner wall surface of the inner cylinder are provided. As the receiving plate is lifted by force, the wheels of the fire pump case are slid on the rails and guide wheels are attached to the upper edge, and since it is a small fire pump case, anyone can easily take out the small fire pump case. There is an effect that can be stored and can be stored.

Since the fire pump storage case housing apparatus of the present invention utilizes the space of the manhole, the mechanism is simple and the cost is low.

Since the operating wheels are attached to the fire pump pump case, the case can be easily moved to an arbitrary place.

Further, since there is sufficient water in the water storage tank in the manhole, there is an effect that there is no obstacle to extinguishing the fire by absorbing water into the water suction pipe.

Since the water storage tank is always provided with a water suction pipe of the fire pump, there is an effect that the fire extinguishing activity can be speeded up.
