JP 2010-1212719 A Japanese Patent No. 5767595 Japanese Patent Laid-Open No. 2015-021796

By the way, in the dry gauze method, since the salt attached to the gauze is separated by rainwater during the rain, it is necessary to install the gauze in the hundreds of boxes. Usually, the 100 leaves box is provided in a rectangular parallelepiped shape, and louvers are provided on the four sides of the 100 leaves box. In such a 100-leaf box, the wind blowing through the 100-leaf box becomes anisotropic. In other words, when the wind blows from a direction perpendicular to the side surface of the 100 leaves box and when the wind blows from a direction oblique to the side face, the angle of the louver differs from the wind direction. The state is different. Therefore, the amount of salt attached to the gauze and the amount of change vary depending on the wind direction.

Therefore, the present invention has been made in view of the above circumstances, and is to make the state of the flow of wind blowing through a rainproof device such as a 100-leaf box the same regardless of the wind direction.

On the bottom plate 12, a plurality of support columns 14 are provided in a state where they are erected at equal intervals in the circumferential direction. These support columns 14 extend vertically between the bottom plate 12 and the top plate 11, the lower end of the support column 14 is connected to the bottom plate 12, the upper end of the support column 14 is connected to the top plate 11, and the top plate 11 and the bottom plate 12 The spacing is maintained by the struts 14.

A lid 13 is provided on the top plate 11, and the opening 11 a of the top plate 11 is closed by the lid 13. The lid portion 13 is connected to the top plate 11 by a hinge 16 so that the opening 11a of the top plate 11 can be opened and closed. The lid 13 may be detachable from the top plate 11 so that the opening 11a of the top plate 11 can be opened and closed.

The rainproof plate 15 is shaped like a truncated conical surface and is inclined downward in the radial direction. Accordingly, the inner surface and the outer surface of the rainproof plate 15 are both truncated cone surfaces, and the upper end and the lower end of the rainproof plate 15 are open. In addition, it is preferable that the inclination | tilt angle of the rain-proof board 15 on the basis of a radial direction (horizontal direction) is less than 45 degrees.

These rainproof plates 15 are stacked between the top plate 11 and the bottom plate 12 with an interval in the vertical direction. The rainproof plates 15 have the same central axis extending in the vertical direction, and these rainproof plates 15 are arranged coaxially. The rainproof plate 15 is fixed to the support 14 by, for example, adhesion, welding or welding in a state where the support 14 penetrates the rainproof plate 15 up and down. Thereby, the space | interval of the rain-proof board 15 adjacent is maintained by the support | pillar 14. FIG. Moreover, the rigidity of the rainproof board 15 improves by the support | pillar 14, and a deformation | transformation of the rainproof board 15 can be suppressed.

雨 Rainproof plates 15 adjacent to each other in the vertical direction do not overlap in the vertical direction. That is, the lower end of the upper rainproof plate 15 and the upper end of the lower rainproof plate 15 are aligned in the vertical direction among the rainproof plates 15 adjacent in the vertical direction. In addition, the lower end of the upper rainproof plate 15 is located above the upper end of the lower rainproof plate 15, and the lower side of the upper rainproof plate 15 is below the lower rainproof plate 15. The interval in the vertical direction to the upper end of the rainproof plate 15 may be shortened.

The upper end of the top rainproof plate 15 is joined to the lower surface of the top plate 11. The upper opening of the top rainproof plate 15 and the opening 11 a of the top plate 11 are arranged concentrically, and the upper opening of the top rainproof plate 15 communicates with the opening 11 a of the top plate 11.

As described above, the assembly in which the top plate 11, the bottom plate 12, the plurality of support columns 14, and the plurality of rainproof plates 15 are combined is a cylindrical louver.

The salt traps 20 are disposed inside the rain plates 15, and the salt traps 20 are detachably held inside the rain plates 15 by a holder 30.
The salt trap 20 includes a gauze 21, a gauze holder 22, an end plate 23, an end plate 24, a shaft 25, a shaft 26, and a tray 27.

The gauze holder 22 is formed in a cylindrical shape. The gauze holder 22 is dotted with numerous holes that communicate with the inside and outside of the gauze holder 22. For example, the gauze holder 22 may be a net material rolled into a cylindrical shape or a perforated plate formed in a cylindrical shape.

A gauze 21 is wound around the gauze holder 22. The gauze 21 is a breathable material that can capture salt scattered in the atmosphere. The gauze 21 is marked with a non-conductive ink.

The end plate 23 is attached to the upper end of the gauze holder 22, and the end plate 24 is attached to the lower end of the gauze holder 22. A shaft 25 is provided on the upper end surface of the end plate 23, and a shaft 26 is also provided on the lower end surface of the end plate 24. These

shafts

25 and 26 extend vertically and are arranged coaxially. The

shafts

25 and 26, the gauze holder 22, and the gauze 21 are also arranged coaxially.

A tray 27 is disposed below the end plate 24. The saucer 27 is provided in a disc shape, and a convex edge 27 a is formed on the outer edge of the upper surface of the saucer 27. The shaft 26 is coupled to the tray 27 so as to penetrate the center of the tray 27 vertically. The receiving tray 27 is larger in diameter than the end plate 24 and is arranged in the vicinity of the end plate 24 so that the salt content dropped from the gauze 21 is accumulated.

The salt trap 20 configured as described above is held by the rainproof device 10 by the holding tool 30 so that the

shafts

25 and 26 overlap the central axis of the rainproof plate 15. The holder 30 includes a support plate 31, a mounting plate 32, and a fixing band 33.

The support plate 31 is formed in a strip shape. The support plate 31 is attached to the upper surface of the bottom plate 12 so as to straddle the opening 12 a along the diameter direction of the bottom plate 12. A bearing recess 31 a is formed at the center of the upper surface of the support plate 31, and the bearing recess 31 a is disposed at the center of the bottom plate 12. The shaft 26 is erected on the support plate 31 in a state where the lower end of the shaft 26 of the salt trap 20 is fitted in the bearing recess 31a.

The mounting plate 32 is formed in a band plate shape. The mounting plate 32 is attached to the lower surface of the top plate 11 so as to straddle the opening 11 a along the diameter direction of the top plate 11. A notch 32 a extending from one end in the width direction to the center in the width direction is formed in the center portion in the longitudinal direction of the mounting plate 32. The shaft 25 is inserted into the notch 32a. The shaft 25 is fastened to the mounting plate 32 so as to be abutted against the end of the notch 32 a by the fixing band 33. The fixed band 33 is endless rubber, and the fixed band 33 is hung on the shaft 25 on the upper side and the lower side of the mounting plate 32.

The lower end of the shaft 25 is fitted into the bearing recess 31a, and the shaft 26 is abutted against the end of the notch 32a, so that the central axes of the

shafts

25 and 26, the gauze holder 22 and the gauze 21 overlap the rainproof plate 15 with the central axis. The

shafts

25 and 26, the gauze holder 22, the gauze 21 and the rainproof plate 15 are arranged coaxially.

The scattered salt content capturing apparatus 1 configured as described above is installed outdoors so that the

shafts

25 and 26 are along the vertical direction, and the direction written on the gauze 21 matches the actual direction.
Since there is a gap between the adjacent rainproof plates 15, the wind blows through the gap from the outside of the rainproof plate 15 to the outside via the inside. In particular, since the rainproof plates 15 adjacent to each other in the vertical direction do not overlap in the vertical direction, the wind and scattered salt are easily passed between the rainproof plates 15. Moreover, if the inclination angle of the rainproof plate 15 is gentle, such as less than 45 °, the wind and scattered salt will pass between the rainproof plates 15. An amount of salt corresponding to the wind speed of the wind blowing from the outside of the rainproof plate 15 through the inside to the outside and the salt density in the air adheres to the gauze 21.
In addition, since the rainproof plate 15 is formed in a truncated conical surface, the wind blowing from the outside of the rainproof plate 15 through the inside becomes isotropic, and even if the wind direction changes, the rainproof against the wind direction The angles of the plates 15 are always equal. That is, when the rainproof plate 15 is viewed from above, the wind hits almost perpendicularly to the outer peripheral edge of the rainproof plate 15 regardless of the wind direction, and passes through the inside from the outside of the rainproof plate 15 to the outside. The wind that blows through the air flows along the radial direction. Therefore, the wind surely blows through the gap of the rainproof plate 15 regardless of the wind direction, and the state of the wind flowing from the outside of the rainproof plate 15 to the outside through the inside becomes the same regardless of the wind direction. And since the gauze 21 is formed in the cylindrical shape, the salt which has come to the scattering salt content capture device 1 adheres to the gauze 21 regardless of the direction of flight. Therefore, the amount of captured salt can be measured for each wind direction.

Since the gauze 21 and the rainproof plate 15 are arranged coaxially, even if the direction of the wind that blows through the rainproof device 10 changes, the manner of wind against the gauze 21 does not change.

Moreover, since a large number of holes are formed in the gauze holder 22, even if the gauze 21 is wound around the gauze holder 22, the air permeability of the gauze 21 is ensured. Therefore, the wind that blows through the inside of the rainproof plate 15 passes through the gauze 21 and the gauze holder 22, and salt content tends to adhere to the gauze 21.

In case of rain, rainwater is blocked by the rain barrier 15. Even if the rainproof plates 15 adjacent in the vertical direction do not overlap in the vertical direction, the vertical position of the lower end of the upper rainproof plate 15 is aligned with the vertical position of the upper end of the lower rainproof plate 15. In the case of rain, rainwater flying by the wind hardly enters the gap between the upper rainproof plate 15 and the lower rainproof plate 15. Moreover, since the rainproof board 15 inclines downward toward the radial direction outward, the rainwater adhering to the outer surface of the rainproof board 15 flows down to the outer side of the rainproof board 15, and it can suppress infiltration of rainwater. Therefore, it is possible to prevent the salt attached to the gauze 21 from being washed away by rain.

Even if the salt content is removed from the gauze 21, the salt content is received by the tray 27. Even if rainwater enters the inside of the rainproof plate 15, salt content is received by the tray 27 together with rainwater to which the gauze 21 is attached. Therefore, the amount of salt that has fallen from the gauze 21 to the tray 27 can be added to measure the amount of salt captured by the gauze 21 and the accuracy of measurement of the amount of scattered salt can be increased.

Next, a method for removing the salt trap 20 will be described.
First, the lid 13 is opened. Next, the fixing band 33 is removed from the shaft 25 and the mounting plate 32. Next, the shaft 25 is removed from the notch 32a by tilting the salt trap 20. Then, the lower end of the shaft 26 is pulled upward from the bearing recess 31 a of the support plate 31, and the salt content capturing body 20 is lifted onto the opening 11 a of the top plate 11. Next, the lid 13 is closed.
The salt trap 20 may be moved out of the rainproof plate 15 by descending from the opening 12 a of the bottom plate 12.

Next, a method for attaching the salt trap 20 will be described.
First, the lid 13 is opened. Next, the salt trap 20 is inserted into the opening 11 a from above the top plate 11, and the lower end of the shaft 26 is fitted into the bearing recess 31 a of the support plate 31. Next, the fixing band 33 is hung on the shaft 25 under the mounting plate 32, and the shaft 25 is inserted into the notch 32a. Next, the fixing band 33 is hung on the shaft 25 above the mounting plate 32, the shaft 25 is abutted against the end of the notch 32 a by the elastic force of the fixing band 33, and the shaft 25 is attached to the mounting plate 32 by the fixing band 33. tighten. Next, the lid 13 is closed.
