Description

[Detailed description of the invention] Industrial application field The present invention relates to a discharge pipe device for an underground fire extinguishing water tank, and in particular, the present invention relates to a discharge pipe device for an underground fire extinguishing water tank, and in particular, it is possible to supply water from a special fire hydrant pillar-shaped outlet without pumping water from a water tank manhole. It was done as possible.

BACKGROUND TECHNOLOGY An underground fire prevention water tank or fire extinguishing water tank installed outdoors stores approximately 40 to 50 tons of water by pouring water through a manhole installed in its canopy, and is used for emergency purposes such as extinguishing fires. They opened the manhole and put the water pump's suction hose into the water tank to pump up the water.

Problems that the invention aims to solve By the way, in this type of outdoor fire extinguishing water tank, the manhole cannot be opened easily because it is rusted or covered with soil, asphalt, etc., and as a result, it takes time to extinguish the fire. It was a lot.

Therefore, the object of the present invention is to develop a discharge pipe device for a fire extinguishing water tank to which a water suction hose of a water discharge pump can be directly connected so that water can be pumped without opening and closing the manhole of the water tank.

Means for solving the problem According to the present invention, the purpose is to attach a suction discharge pipe to an underground fire extinguishing water tank, and to connect the pipe so that at least the water level is underground. This can be achieved by a discharge pipe device for a fire extinguishing water tank, which is constructed by burying a pipe and providing a discharge port with a cap at the end area of the pipe that projects above ground.

Function The fire extinguishing water tank is equipped with a discharge pipe in advance.
The tip of the pipe was made to protrude above the ground from the underground part, and a discharge port with a cap was provided at the tip.The cap of the discharge port was removed and the water suction hose port of the water discharge pump was connected to it. It can be connected by screwing or plugging means, and by operating the pump, the water stored in the fire extinguishing water tank can be pumped up and discharged.

In this case, it becomes possible to easily perform the water receiving operation for extinguishing a fire without requiring the operation of opening the manhole of the fire extinguishing water tank.

Embodiment FIG. 1 is a layout configuration diagram showing an embodiment of the device of the present invention. A fire extinguishing water tank 1 buried underground has a discharge pipe 2 whose suction port reaches the bottom of the tank 1. The outer end of the pipe 2 is connected to a straight pipe 2a buried underground and an upper copper pipe 2b protruding above the ground in sequence. A water outlet 3 is provided in the tip region of the upper copper 2b. Additionally, 4 indicates a manhole for water injection.

FIG. 2 is a half-cut sectional view showing an example of the straight pipe 2a and the upper copper 2b, and FIG. 3 is a plan view thereof, showing the connections between the straight pipe 2a and the discharge pipe 2 or the upper copper 2b. A hexagonal bolt/nut 6 is tightened between them under the abutment of a flange 5 provided at the connecting end.

The water outlet 3 consists of a fitting type joint opening, and the opening end is covered with a cap 9 connected by a chain 8 having one end attached to a chain stop 7 provided on the outer wall of the upper copper 2b. On the other hand, the upper copper 2b
A stopper 10 is screwed into the tip of the stopper 10 to seal it, and a bowl-shaped cap 11 is placed over the outside of the stopper 10. Additionally, 12 indicates an O-ring for sealing.

According to the embodiment of the present invention having such a configuration,
The water in the fire extinguishing water tank 1 is always guided to the straight pipe 2a buried underground in the discharge pipe 2, and therefore the water suction hose of the water discharge pump is connected to the water discharge port 3 provided in the upper copper 2b of the discharge pipe 2. By connecting the mouth, it is possible to pump up the water for fire extinguishing purposes.

Moreover, since the upper channel 2b stands on the side of the water tank and the water outlet 3 is covered with a cap 9, the hose port can be connected by removing the cap 9 when using the port 3 to prevent dust and rust. In the event of an emergency, a fire engine or a pump truck can be dispatched and quickly connected to the discharge pipe 2 of the fire extinguishing water 1 near the scene to spray water.

Effects of the invention As described above, according to the invention, a suction discharge pipe is attached to an underground fire extinguishing water tank, and a discharge outlet with a cap is provided at the end area of the pipe that projects above the ground. In an emergency, by directly connecting the pump water intake hose port to the discharge port, fire extinguishing operations can be carried out quickly, and the troublesome work of opening the manhole of the fire extinguishing water tank can be omitted during such extinguishing operations. , it has excellent responsiveness to emergencies, and since there is no need for inspection and maintenance of the manhole during the winter, it can save the effort of maintenance work, and it also saves extra effort such as finding the location of the manhole during snowfall and at night. In addition, since a part of the discharge pipe was buried underground so that the water level was underground, The device of the present invention is extremely effective in practical use, as it prevents freezing and allows the user to always be prepared for emergencies.
