Description

[Detailed explanation of the idea] The present invention relates to a ventilation device for a ventilation container.

As shown in FIGS. 1 to 3, a conventional ventilation system for a ventilation container has a large number of ventilation windows 3 provided in an outer wall 2 such as a side wall, end wall, or door of a container 1, as shown in FIG. In this structure, outside air is introduced into the room through a ventilation cover 4 in which a part of the wall surface is bent toward the indoor side and an opening is formed above.

With such a ventilation structure, when the container 1 is loaded on a trailer or freight car and driven, rainwater easily enters through the ventilation window 3, and the loaded items become dirty or discolored by the rainwater, so improvements are strongly desired. was.

Therefore, the present invention was devised in order to solve the above-mentioned drawbacks, and it involves providing a large number of small-diameter ventilation holes in the outer wall of the container, and opening a ventilation cover that covers the group of ventilation holes from above on the indoor side of the outer wall. It is characterized by having its sides and lower part joined to the wall surface, and its purpose is to
An object of the present invention is to provide a ventilation device that prevents rainwater from entering.

An embodiment shown in FIGS. 4 and 5 will be described below. A large number of small-diameter ventilation holes 5 are bored in the outer wall 2 of the container 1, and the ventilation holes cover the ventilation hole group 6 consisting of an appropriate number of ventilation holes 5. cover 7
on the indoor side of the outer wall 2, with the upper part 7a opened and the side parts 7b, 7b
and the lower part 7C are joined to the wall surface with rivets 8 or the like.

The number of ventilation holes 5 is calculated and determined from the total area required for ventilation.

Since the present invention is constructed as described above, the ventilation cover 7 completely covers all of the ventilation holes 5, so that the intrusion of rainwater is sufficiently prevented and the ventilation effect is not hindered.

Next, an example of a comparative test conducted to demonstrate the effectiveness of the present invention is shown below.
