AI Technical Summary
Standard suction strainers for large pumps require deep water depth to prevent air intake, making shallow suction impossible, especially in flooded areas during heavy rainfall where water is not deep enough, and they lack visibility or recesses for easy installation.
A suction strainer with a flat, closed underside and inlet openings near the bottom, designed to float with buoyancy aids when water is deep enough, preventing debris suction from the bottom.
Enables shallow suction in shallow water conditions by floating and maintaining effective debris prevention from the bottom.

Abstract
Description
[0001] Large pumps are used in disaster relief and firefighting. The standard suction strainers supplied by the manufacturers have openings on all sides to provide the largest possible suction area. This means that a great water depth is required to prevent air from being drawn in.
[0002] Shallow suction is not possible with these suction baskets. During heavy rainfall, large areas are often flooded, but the water is not particularly deep. Recesses for inserting simple suction baskets are often either not present or not visible.
[0003] This design solves the problem. The suction strainer is designed with a flat, closed underside. The inlet openings are positioned close to the bottom. The cross-section of the inlet openings is larger than the cross-section of the hose coupling. Attachment points for buoyancy aids are provided, allowing the suction strainer to float when the water is deep enough. This prevents the suction of debris from the bottom for as long as possible.
Claims
[1] Suction strainer with carrying handles for shallow suction with large pumps (DN 150mm) characterized by that the underside is designed to be flat and closed, so that the suction basket can be pushed into the conveyed medium over fixed surfaces. [2] Suction basket according to claim 1 characterized by that the inlet openings are located close to the bottom so that as little air as possible is sucked in at shallow water depths. [3] Suction basket according to one of the preceding claims, characterized by , the inlet openings are dimensioned in such a way that, despite the flat design, there is no cross-sectional narrowing compared to the suction hose. [4] Suction basket according to one of the preceding claims, characterized by , that options for attaching buoyancy aids are appropriate to make the use more flexible.
