Description

Spattering salt capture device

The present invention relates to a scattered salt capturing device that captures salt scattered in the atmosphere in order to measure the amount of scattered salt.

In order to predict salt damage caused by sea salt particles such as insulators and steel towers in power transmission systems, the amount of salt scattered in the atmosphere (hereinafter, the amount of salt contained in the unit volume is the amount of salt in the air, and this is multiplied by the wind speed). It is necessary to measure the amount of salt (sprayed salt content), and for that purpose, it is necessary to capture the salt scattered in the atmosphere. The dry gauze method stipulated in JIS Z2382 is to install gauze in a wooden frame with open windows and install it in a well-ventilated place where it does not get wet in the rain, and measure the amount of salt attached to the gauze. In addition, the air salinity measurement method described in Patent Document 1 is to suck outside air and dissolve it in water, and measure the amount of salt based on the conductivity of the aqueous solution.

A cover 30 that holds the upper cover 30 and the upper cover 30 is movable up and down between the upper stage and the middle stage, and the lower cover 30 is held up and down between the middle stage and the lower stage. And. An annular sealing material 148 having a diameter larger than that of the circular hole 36 A is attached to the lower surface of the upper cover 30, and the space between the upper and lower covers 30 is shielded by the sealing material 148.

The scattered salt capturing device 100 having the above-described configuration is shielded from the outside air by covering the upper salt capturing body 20 with the upper cover 30 and is shielded from the outside by covering the middle salt capturing body 20 with the lower cover 30. Installed at the observation site. Then, the scattered salt content is captured by the exposed lower salt content capturing body 20 for a predetermined period (for example, one month). Then, the lower cover 30 is lowered to cover the lower salt capturing body 20 with the cover 30 and shielded from the outside air. Then, the scattered salt content is captured for a predetermined period (for example, one month) by the exposed middle salt content capturing body 20. Then, the upper cover 30 is lowered to the middle stage, and the middle stage salt trap 20 is covered with the cover 30 to shield it from the outside air. As a result, the amount of scattered salt can be observed continuously for a period of three times as compared with the case where one salt trap 20 is installed in the 100-leaf box 1, and the exchange frequency of the salt trap 20 is reduced to 1 /. It can be reduced to 3.
