JPH11107331A - Strainer for fire pump water suction pipe - Google Patents

Abstract

PROBLEM TO BE SOLVED: To save the time for installation by providing a suction pipe strainer with a pipe sucking rope fitting, and providing a screw part for fitting a dust guard basket. SOLUTION: In the case of throwing a water suction pipe 4 of a fire pump into water, a suction pipe strainer 1 is screwed and fitted in the tip of the water suction pipe 4 to fit pipe sucking ropes 3a, 3b to a fitting 1b. In the case where two or more suction pipe ropes are needed, fitting can be facilitated by providing the fitting 1b. In the case where the stainer is floated in the water and fixed, the strainer in such a state is thrown into water and the pipe sucking ropes 3a, 3b are drawn moderately to stabilize the suction pipe strainer 1. In the case where the depth of water is shallow so that the suction pipe strainer 1 comes into contact with the bottom, a dust guard basket 2 is fitted to the outside of the suction pipe strainer 1. As the dust guard basket 2 is screw-type, it can be fitted simply and surely. Accordingly, handling of a water suction pipe can be simplified and facilitated, and sure operation can be conducted.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a strainer for a suction pipe, a garbage basket, and a suction pipe float used in a fire pump.

[0002]

2. Description of the Related Art A conventional fire pump pump suction pipe strainer (hereinafter referred to as suction pipe strainer) has a shape as shown in FIG. 5 and is made of resin or copper. 7 to prevent dust from entering the pump
This is a cylindrical device having a hole 1c of about mm in the surface. This is attached to the tip of the water suction pipe 4 and put into the water when the fire pump is used. At that time, for fixing the water absorption pipe 4,
Attach the suction pipe pulling rope 3 (hereinafter referred to as suction pipe rope) used when pulling the water suction pipe 4. If there is water depth and the suction tube strainer 6 can be fixed in a floating state, it is good, but if there is no water depth and the suction tube strainer 6 comes into contact with the bottom, further attach a dust basket 5 outside the suction tube strainer 6. The suction tube strainer 6 prevents the water absorption performance from dropping at the bottom. Conventional suction rope 3
The tip of the rope was tied to the end of the water absorption pipe 4 and used. This was a time-consuming and not very reliable method. In addition, in places where water flows rapidly, two ropes for fixing may be required, making the operation more time-consuming. Further, the conventional dust basket 5 has a shape in which a wicker vine is knitted in a cage shape and a cloth 5a with a string 5b is attached thereto. At the time of attachment, the suction tube strainer 6 is put over from above and fixed with the string 5b. This is also troublesome and lacks certainty.

It goes without saying that fire fighting is an urgent matter. However, the difficulty of handling due to the lack of performance of such equipment related to fire-fighting suction pipes is currently being compensated by training. It has been a long-felt need for those engaged in fire fighting to improve the performance of such equipment so that fire fighting can be performed quickly and reliably. The present invention has been invented in order to respond to such strong demands of users.

[0004]

As shown in FIG. 1, a suction pipe strainer 1 is provided with a metal fitting 1b for mounting a suction rope 3, and a screw portion 1a for mounting a dust basket 2 is provided. The dust basket 2 is integrated with the mounting screw. The suction pipe float 9 can be mounted using the screw part 1a for mounting the dust basket 2.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of the present invention will be described. When the water suction pipe 4 of a fire fighting pump is poured into water, the suction pipe strainer 1 is first screwed into the tip of the water suction pipe 4 and attached. Next, the suction ropes 3a and 3b are attached to metal fittings. 2
Even if more than one suction rope is required, it can be installed very easily because the mounting bracket is provided. If it can be floated and fixed in water, it is poured into water in this state, and the suction ropes 3a and 3b are appropriately pulled to pull the suction pipe strainer 1
Stabilize. When the suction tube strainer 1 comes into contact with the bottom due to shallow water depth, attach a dust basket 2 outside the suction tube strainer 1. The dust basket 2 can be easily and securely attached because it is a screw-in type. If the dust basket 2 is completely buried in algae or the like in the flow or on the shore, attach the suction tube float 9 to the suction tube strainer 1.
The suction tube float 9 can be easily attached by using the screw portion 1a of the suction tube strainer 1.

[0006]

[Effect of the Invention] Fire fighting is one minute and one second,
When operating a fire pump, handling of water intake pipes occupies a large weight. According to the present invention, handling of the suction pipe becomes very simple and easy, and moreover, reliable operation becomes possible.
