Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water absorption pipe strainer for a fire fighting pump to be attached to a flexible water absorption pipe for a fire fighting pump such as a fire engine or a portable small pump.

[0002]

2. Description of the Related Art As shown in FIG. 3, a conventional water absorption pipe strainer for a fire fighting pump is provided with a water absorption hole 3 over the entire area of a cylindrical strainer portion 2, and is provided substantially in the center of the upper surface in the axial direction of the strainer portion 2. An extended male media fitting 6 is attached. When using the suction pipe strainer for this fire pump, since in the suction pipe having a flexibility that is connected to the male-mediated fitting 6 can not be water if not vacuum, strainer portion you close the water surface of the river In order to prevent air from being sucked in from the water absorption holes 3 of 2, the water depth needs to be about 30 cm.

[0003]

However, in the conventional water absorption pipe strainer for a fire pump, since the water absorption hole 3 is provided in the entire area of the cylindrical strainer part 2, the water depth is about 10 cm. If you water like rivers, by drawing air from the water hole 3 strainer section 2 you located near the water surface, the water absorption impossible. Therefore, water depth in the shallow rivers as 10 centimeters, in order to avoid breathing air from the water hole 3, is swollen by damming a river, there has been necessary to deeply water depth.

[0004]

SUMMARY OF THE INVENTION The fire water pipe Strainer for pump of this invention has been made to solve the disadvantages mentioned above, Bian flat shape in which water hole only on the side surfaces other than the bottom and top provided The strainer part, and one end side is attached to substantially the center of the upper surface of the strainer part,
L whose other end extends outward in proximity to the strainer portion
And a U-shaped tube. And the other end of the tube
As you go to the outside of the strainer section,
It is desirable to lower to the part side.

[0005]

[Action] to the tube body in the fire water pipe Strainer for pump of this invention, connecting a water suction pipe having flexibility extending from the firefighting vehicle position apart horizontally Then, the water suction pipe
Is bent and comes into contact with the riverbed. Thus, the water absorption pipe
The strainer part is flat even if it is bent and touches the bottom of the river.
It is flat, and the tube extends from the center of the top of the strainer part to the outside.
Because it extends in an L-shape near the strainer part,
The stress that holds down the water absorption pipe side of the trainer part and lifts the opposite side from the water absorption pipe , that is, the strainer part
It generates only little force for rotating the strainer portion
Is installed in a horizontal stable state riverbed river.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. First, strainer section 2, iron, stainless steel, aluminum, is formed in the material by Bian flat shape, such as copper or resin,
The water absorption holes 3 are provided only on the side surfaces other than the bottom surface and the top surface. An elastic plate made of rubber or the like is attached to the strainer portion 2 so as to protrude from the side as an air suction preventing portion 4 on the upper surface, and an elastic plate made of rubber or the like is attached to the bottom surface. The suction prevention portion 5 is attached so as to protrude from the side surface. Further, one end is attached to the upper surface of the strainer portion 2 substantially at the center, and the other end is close to the strainer portion 2 and the outer side is closer to the outside.
The L-shaped tube 1 descending to the laner part 2 is a strainer
It extends to the outside of the part 2 . In addition, the handle | tube 7 which attached the stay rope 8 to the upper part is provided in the pipe body 1, and the male intermediate metal fitting 6 is provided in the other end.

When using the water suction pipe strainer for a fire pump of the present invention, the handle 7 is held and the male fitting 6 is held.
Is connected to a female fitting of a flexible water-absorbing pipe such as a fire engine and the like, and the retaining rope 8 is held and is inserted horizontally into a river. When the water suction pipe strainer for the fire pump is put into the river in this way, the lower surface of the strainer part 2 becomes the bottom of the river.
And the water intake pipe bends to contact the bottom of the river
However, the strainer part 2 is flat, and the tube 1 is close to the strainer part 2 from substantially the center of the upper surface of the strainer part 2 and is L
Since it extends in the shape of a letter, the stress that presses the water absorption pipe side of the strainer part 2 and lifts the opposite side from the water absorption pipe , that is, the force that rotates the strainer part 2, is small.
The fire pump suction pipe strainer is installed horizontally and stably at the bottom of the river. In addition, the tube
The body 1 moves out of the strainer part 2
As it descends to the side of the
Hold down the water tube side and hold the water tube on the opposite side.
Water absorption for fire pump
The pipe strainer is more stable horizontally at the bottom of the river
Installed in The strainer section 2 is in Bian flat, since the water holes 3 only on the side surfaces other than the bottom surface and the top surface are provided, it can be water from the side, without sucking air from the water surface in shallow water depths river water can do. Further, as shown in FIG. 4, if a fine net-like member or the like is provided as a dust remover 9 on the outer periphery of the air suction preventing portion 4 and the dust suction preventing portion 5, clogging of the water absorbing hole 3 can be prevented. Can be.

[0008]

[Effect of the invention] As described above, according to the invention, the pipe body
And extended from a fire engine located horizontally away
When a flexible water intake pipe is connected , the water intake pipe will bend and bend.
It touches the riverbed, etc., but the strainer is flat and
A tube is inserted into the strainer from approximately the center of the upper surface of the laner.
Since it is close to and extends in an L-shape, the stress that presses the suction pipe side of the strainer part and raises the side opposite to the suction pipe , that is, the force that rotates the strainer part, is reduced.
Generates only slightly, Ru can the water suction pipe strainer for fire pumps installed in a state of horizontally stabilized in such riverbed of a river. In addition, the tube goes outside the strainer section
As it descends to the strainer section,
While holding down the suction tube side of the
The fire that lifts the opposite side is even smaller,
Pump suction pipe strainer horizontally on the bottom of a river
It can be installed in a more stable state. Further, strainer portion at Bian flat, since only the water hole sides except the bottom surface and the top surface is provided, it is possible to water from the side, a very effective without sucking air from the water surface in shallow water depths rivers Can absorb water. Therefore, there is no need to dam the river, and quick firefighting activities can be performed. Also, even if the water depth is shallow
The range of available water sources for fire trucks jumps because water can be taken
Fire engines will greatly contribute to firefighting activities
be able to.
