  This watering tank cover member 10 supplies cooling water upward from a water pipe 6 disposed through the bottom plate 5 a of the watering tank 5 and sprays the cooling water from the watering tank 5 to the filler 3 as in the prior art. This is used for the cooling tower 1 that is brought into contact with the outside air and lowers the cooling water temperature by heat of vaporization, and is placed so as to cover the upper part of the watering tank 5 including the upper part of the discharge port 6a of the water pipe 6. It is.

  In this case, the water sprinkling tank cover member 10 is formed by hanging the side plates 10b, 10c, and 10d from the periphery of the top plate 10a so that no gap is formed between the side plates 10b, 10c, and 10d. The member 10 is formed in a box shape having an open bottom.

As long as the size of the cover member 10 for the water sprinkling tank can cover at least a predetermined range above the discharge port 6a of the water pipe 6, the water sprinkling tank 5 has the same size as that described in the present embodiment. It does not have to be large enough to cover the entire upper part, and the overall dimensions can be made smaller than those described in this embodiment.
And when using the cover member 10 for watering tanks smaller than the watering tank 5, the opening part A which a cooling water passes to the lower end edge of the side plate 10b which does not contact the side wall of the watering tank 5 is used as the side edge 12 of the side plate 10b. The cooling water flowing out from the opening A is scattered outside by forming except for the vicinity area (which can be appropriately set according to the flow rate of the cooling water, but usually about several centimeters). While preventing, cooling water can be supplied to the whole sprinkler tank 5.

  The method for manufacturing the water sprinkling tank cover member 10 is not particularly limited. For example, the water spray tank cover member 10 may be manufactured by bending an iron plate as shown in the development view of FIG. 1B (in this case, the top plate).

It hits the inner surface, flows under the sprinkler tank cover member 10 that covers the sprinkler tank 5, and is supplied to the whole sprinkler tank 5.
At this time, when the flow rate of the cooling water supplied from the water supply pipe 6 is fast, the cooling water is emptied from the top of the water spray tank cover member 10 even if the water spray tank cover member 10 is temporarily lifted by the cooling water blowing power. After flowing along the inner surface of the plate 10a, the side plates 10b, 10c and 10d are guided from the peripheral edge of the top plate 10a to the side plates 10b, 10c and 10d suspended so that no gap is formed. As long as it overlaps (as long as the side plates 10b, 10c, and 10d and the side wall of the water sprinkling tank 5 are wrapped), it is possible to reliably prevent the cooling water from splashing outside.
And the cooling water supplied to the whole sprinkler tank 5 is sprinkled by the filler 3 from the sprinkle hole 5c drilled many by the bottom plate 5a of the sprinkler tank 5. FIG.

  Moreover, when using the cover member 10 for watering tanks smaller than the watering tank 5 like a present Example, the opening part A which a cooling water passes to the lower end edge of the side plate 10b which does not contact the side wall of the watering tank 5 is provided. The cooling water is supplied to the entire sprinkling tank 5 while preventing the cooling water flowing out from the opening A from being scattered outside by forming except for the vicinity of the side edge 12 of the side plate 10b. Can do.

  Further, as in the present embodiment, the lower end edge of the side plates 10c, 10d of the water spray tank cover member 10 in contact with the side wall of the water spray tank 5 extends inward of the water spray tank cover member 10 to form a strip-shaped bottom piece 11. By doing so, the weight of the cooling water flowing along the side plates 10c, 10d is applied to the strip-shaped bottom piece 11, and it is possible to prevent the water sprinkling tank cover member 10 from being lifted by the blowing power of the cooling water. it can.
