[Prior Art] A conventional device is disclosed in Japanese Patent Application Laid-Open No. 58-18641.
As described in Publication No. 1, the lower part of the collection grid is used as a collection container, and a guide member is provided in the range of the obliquely extending end of the collection container,
Filter devices are known in which the width of the guide member is narrower than the spacing of the side walls of the collection container and is oriented in the direction of the outlet of the cleaning member, separating the cleaning member from the cooling water flow. However, this known technology has two drawbacks: that the cleaning member can be stably collected against drifting flow from the upstream side, and that a large amount of foreign matter (for example, fallen shellfish from the cooling water outflow wall surface) is temporarily collected from the upstream side.
There was a problem in that the cleaning member outlet, which opens toward the upstream side, was blocked by the inflow of the cleaning member.

On the other hand, a rectifying vane 6 is provided at the downstream end of the rectifying member 5, and maintains an interval at which it can easily roll within the duct 4, and forms both slopes in a valley shape with the lowest point at the center. The lowermost end thereof is connected to the cleaning body extraction port 7 at the inner end of the body of the cleaning body extraction pipe 3. Therefore, the flow on the collection grid surface and in the duct 4 is disturbed by the rectifier vane 6, and it is possible to prevent the cleaning body from adhering to the grid or stagnation in the duct 4. Moreover, since the extraction port 7 of the cleaning body extraction pipe 3 that sucks up the cleaning body toward the upstream side faces the downstream side, even if a large amount of foreign matter, etc. temporarily flows in from the upstream side, the foreign matter will flow along the main stream. Only the cleaning body is captured by the collection grid 2 and sucked up by the extraction tube 3.

[Effects of the Invention] According to the present invention, the streamlines on the inlet side of the body of the cleaning body collection device can be rectified against the drifting flow from the upstream side, so that the cleaning body can be moved along the rectified streamlines. The cleaning body flows into the body of the collection device as a straight flow, and the streamlines passing through the shielding member cause the cleaning body to flow toward the entrance of the cleaning body extraction pipe, so that the components flowing at right angles to the collection grid surface are This makes it possible to prevent the cleaning body from adhering to and stagnation on the collecting grid surface. Furthermore, even if the cleaning body adheres to the collection grid surface and stagnates, the flow near the collection grid can be made turbulent by intersecting the straight flow and the streamlines that have passed through the shielding member.
Since the cleaning body can be removed, high recovery performance (high recovery rate) can be obtained.

[0024] Furthermore, since the rectifying vane is provided at the lower end of the rectifying member and the cleaning body is sucked upstream,
The extraction port faces downstream, and even if a large amount of foreign matter temporarily flows in from the upstream side, the foreign matter will be captured by the collection grid along the mainstream, so only the cleaning body will be exposed to the cleaning body extraction port. This prevents the extract from being sucked up and clogging the extraction port.
