JPH0648807U - Water absorption pipe strainer for fire pump - Google Patents

Abstract

(57) [Summary] [Objective] This relates to a water absorption pipe strainer that is attached to the tip of the water absorption pipe of a fire engine in firefighting operations.
Due to the flat formation, when water for extinguishing a fire is taken from a river, water can be absorbed even in a river with a shallow water depth, and fire extinguishing activities can be carried out quickly. [Structure] The strainer part (2) is formed in a flat shape, and the water absorption holes (3) are arranged only on the outer peripheral side surface other than the bottom surface and the top surface, and the male medium metal fitting (6) is used to connect the female part in the water absorption pipe of the fire engine. It is used by mounting it on the media fitting.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a water absorption pipe strainer for a fire pump, which is attached to a water absorption pipe for a fire pump such as a fire engine or a portable small pump to absorb fire extinguishing water from a shallow river. .

[0002]

[Prior art]

 The water absorption pipe strainer for a conventional fire pump has a cylindrical shape, and water absorption holes are arrayed over the entire surface. The water depth is large enough to prevent air from being sucked through the water absorption holes of the strainer near the water surface of the river. It took about 30 centimeters. In addition, pumps for fire fighting such as fire trucks cannot absorb water unless the inside of the water absorption tube is in a vacuum state when absorbing water, and the inclusion of air was the cause of water absorption failure.

[0003]

[Problems to be solved by the device]

 This had the following drawbacks. Since water absorption holes are arranged in a cylindrical shape over the entire surface, when absorbing water in a concrete river with a water depth of about 10 cm, air is sucked from the water absorption holes of the strainer near the water surface and water cannot be absorbed. Therefore, a dam was needed to increase the water level in the river so that air would not be sucked in.

[0004]

[Means for Solving the Problems]

 When water is absorbed in a shallow river such as a concrete river, the structure is as follows because air is not sucked in from near the water surface. The strainer part (2) is formed flat, and the water absorption holes (3) are arranged and provided only on the outer peripheral side surface other than the bottom surface and the upper surface. A water absorption pipe strainer for a fire pump constructed as described above.

[0005]

[Operation] When using this, hold the handle (7), connect the male intermediary fitting (6) to the female intermediary fitting of the water intake pipe for the fire hydrant, such as in a fire truck, and attach the rope (8). Hold and put the body (1) horizontally into the river. The strainer part (2) placed horizontally on the bottom of the river is flat, and since the water absorption holes (3) are arranged only on the outer peripheral side surface other than the bottom surface and the top surface, it is possible to absorb water from the side. It can prevent the intake of air from the water surface.

[0006]

【Example】

 An embodiment of the present invention will be described below. The strainer part (2) is made of a material such as iron, stainless steel, aluminum, copper or resin, and is formed flat, and the water absorption holes (3) are arranged only on the outer peripheral side surface other than the bottom surface and the top surface. Also, an elastic plate made of rubber or the like is attached to the bottom surface by protruding from the strainer part (2) as the dust suction prevention part (5), and also on the top surface as the air suction prevention part (4). Stick it out. A handle (7) to which a stay rope (8) is attached is provided on the upper part of the main body (1), and a male intermediary metal fitting (6) is provided. This proposal has the above-mentioned structure. When using this, the handle (7) is held and the male intermediary metal fitting (6) is connected to the female intermediary metal fitting of the water intake pipe for the fire hydrant in a fire engine, etc. Hold the rope (8) and throw the main body (1) horizontally into the river. The strainer part (2) placed horizontally on the bottom of the river is flat, and since the water absorption holes (3) are arranged only on the outer peripheral side surface other than the bottom and top surfaces, water can be absorbed from the side and Even shallow rivers can absorb water without sucking air from the surface. Further, as shown in FIG. 2, if a dust-removing tool (9) having a fine mesh is provided on the outer circumference of the strainer section (2), clogging of the water absorption hole (3) can be avoided.

[0008]

[Effect of device]

 The present invention can absorb water very effectively in a shallow river, and can carry out quick firefighting activities without any need for damming the river.
