Description

  The present invention relates to a technique for investigating flying salt content, and more specifically, a multi-directional flying salt collector that can investigate the salt coming from multiple directions separately for each flying direction, and many This is related to the direction of salinity survey method.

  Flying salinity is the sea salt particles that have risen from the sea level to the land. If this flying salt adheres to the surface of a concrete structure near the coast, it penetrates into the interior and causes the reinforcing bars to corrode and expand, reducing the structural strength. Moreover, when flying salt adheres to the bridge near the coast, the steel material which is the main member of the bridge is corroded, and as a result, the member thickness is reduced, and the structural strength is also lowered. Therefore, when constructing a structure such as a bridge near the coast, it is desirable to plan and design in consideration of the effects of corrosion, and in this case, it is common to investigate the amount of incoming salt.

  Moreover, it can be pointed out that flying salt not only corrodes structural members but also affects the growth of crops. As a result of experiments, the inventors of the present application have found that flying salt content affects the growth of agricultural crops, and particularly flying salt content received at an early stage of growth significantly affects growth.

  It is extremely useful to investigate the amount of incoming salt because various effects can be judged. In the past, flying salinity surveys have been conducted by methods such as the Token tank method and the dry gauze method. The Token tank method is a technique to collect the salt content attached to the 10cm x 10cm stainless steel plate together with rainwater and grasp the amount of salt coming in. The dry gauze method is also used to collect the salt content attached to the 10cm x 10cm gauze. It is a technique to grasp the amount of incoming salt. In either case, it is installed outdoors to collect incoming salt, but in the case of the dry gauze method, the gauze is suspended under a cover such as a roof so that it will not be exposed to rainwater.

  Since the dry gauze method is a JIS standard, it has been widely used so far. For example, Patent Document 1 also shows this method.

  FIG. 5 is an explanatory view showing a conventional dry gauze method. As shown in this figure, the conventional dry gauze method collects the flying salt by means of the flying salt collector Cs installed under the roof formed in the shape of four stones. The flying salt collector Cs has a structure in which dry gauze is sandwiched between two frame materials (for example, made of stainless steel) having an inner diameter of 10 cm × 10 cm, and mainly collects flying salt in two directions (two directions from the front and back in the figure). Collect.

  Since the conventional dry gauze method is a method for investigating the amount of salt in two directions, it is necessary to know in advance the direction in which the salt will fly. However, the wind direction varies greatly depending on the season or time of day in the intricate bay. When a person who produces crops in such a land tries to investigate the amount of salt in the air, the conventional dry gauze method can give insufficient results. For example, it is assumed that the conventional dry gauze method is used to investigate the season when the agricultural product reaches the early stage of growth. Then, it is assumed that the amount of salinity is small in the direction targeted by the dry gauze, and that a lot of salt content actually flies from different directions. In this case, if this crop is made in the area based on the survey results, it will receive incoming salt at an early stage of growth, and as a result, the crop will be significantly affected.

  That is, the conventional dry gauze method has been insufficient when flying salinity from multiple directions is assumed. When trying to cope with the conventional dry gauze method to the last, a large number of incoming salt collectors Cs must be installed so that the dry gauze faces in multiple directions. This is not practical because it takes not only installation work but also labor for investigation, and material costs and labor costs are high.

  Therefore, it is conceivable to install an incoming salt collector Cs provided with a plurality of dry gauze facing in multiple directions. FIG. 6 is a view showing an incoming salt content collector Cs using a polygonal housing, wherein (a) is a plan view and (b) is a side view. As shown in this figure, dry gauze Dg is attached to each side surface of a regular octagonal housing in plan view. That is, the incoming salt collector Cs in FIG. 6 includes eight dry gauze Dg facing in eight directions. According to this, it is possible to investigate the amount of incoming salt in eight directions simply by installing one incoming salt collector Cs. However, as shown by the arrows in FIG. 6 (a), there may be a case where salt passes through one dry gauze Dg and adheres to other dry gauze Dg, and this flying salt collector Cs may not be able to investigate correctly. is there.

  The subject of the present invention is to solve the above problem, that is, it is possible to investigate the amount of incoming salt from multiple directions, and an efficient incoming salt salinity survey can be performed without installing a large number of incoming salt collectors. It is possible to provide a multi-directional flying salt collector and a multi-directional flying salt survey method that are possible and can accurately estimate the amount of flying salt by direction.

  The present invention comprises a plurality of collecting cloths that are directed in multiple directions (cloth that collects salt from the body, such as dry gauze), and the airflow that has passed through the collecting cloth does not affect other dry gauze. The invention is based on an idea that has not been used in the past.

  The multi-directional flying salt collector of the present invention collects flying salt by dividing the flying direction, and includes a hollow housing composed of side and bottom surfaces, and a roof material attached to the top of the housing. It is provided. A partition is provided inside the housing, and a plurality of compartments partitioned by the partition are formed inside the housing. A collection window is provided on a side surface constituting the compartment, and a collection cloth for collecting incoming salt is installed in the collection window. On the other hand, vent holes are provided in the bottom surfaces constituting the compartments. In addition, the some collection cloth installed in the some compartment (the side surface) is each arrange | positioned facing the different direction.

  The multi-directional flying salt salinity survey method of the present invention is a method of investigating the amount of flying salt at the survey point separately according to the flying direction, the step of installing a multi-directional flying salt collector at the survey point, multi-directional flying salt collection This is a method comprising a step of recovering two or more collection cloths installed in a vessel and a step of estimating the amount of incoming salt based on the salt content attached to the collected collection cloths. The multi-directional flying salt collector used in this method includes a hollow casing composed of a side surface and a bottom surface, and a roof material attached to the upper portion of the casing. And the partition is provided in the inside of this housing | casing, and the two or more compartments partitioned off by the partition are formed. In addition, a collection window is provided on the side surface that constitutes the compartment, and a collection cloth that can collect incoming salt is installed in the collection window, and a vent hole is provided on the bottom surface that constitutes the compartment. Is provided. In addition, the some collection cloth installed in the some compartment (the side surface) is each arrange | positioned facing the different direction. By collecting two or more collected cloths, the amount of incoming salt is ascertained separately for each flying direction by associating the arrangement direction of the collecting cloth with the amount of flying salt estimated based on the collected cloth.

The multi-directional incoming salt content collector and the multi-directional incoming salinity investigation method of the present invention have the following effects.
(1) By installing only one incoming salt collector, the amount of incoming salt from multiple directions can be estimated for each direction. As a result, an efficient investigation is possible and the cost can be reduced as compared with the conventional method.
(2) A compartment partitioned by a partition is formed inside the housing, and a collection cloth (for example, dry gauze) is installed in a collection window provided for each compartment. Accordingly, since only the amount of salinity in the target direction can be collected, the amount of salinity in each direction can be estimated accurately.
(3) Since the ventilation hole is provided in the compartment inside the housing, the airflow entering the compartment is smoothly discharged outside the housing. Therefore, unnecessary external force (wind force) does not act on the housing, and it can be used for a long time.

  An example of an embodiment of a multidirectional incoming salt content collector and a multidirectional incoming salt content investigation method of the present invention will be described with reference to the drawings.

1. Overall Overview FIG. 1 is a perspective view showing a multidirectional incoming salt collector 100 of the present invention. The multidirectional flying salt collector 100 includes at least a housing 200 and a roof material 300 (shown by a broken line for convenience), and is supported using a support column 400 and the like. Or when the roofing material 300 is supported separately, the housing | casing 200 is attached to the roofing material 300, and the support | pillar 400 grade | etc., Can also be abbreviate | omitted.

  The housing 200 has a hollow structure surrounded by a plurality of side surfaces 210, and a compartment 230 partitioned by a partition wall 220 is provided therein. Each side surface 210 is provided with a collection cloth 240 (for example, dry gauze) that can collect salt. As shown in FIG. 1, the plurality of side surfaces 210 constituting the housing 200 are arranged in different directions, so that the collection cloth 240 also faces in different directions. The incoming salt can be collected.

  Hereinafter, it explains in full detail for every element which comprises this invention. Here, the case 200 is described as having four side surfaces 210 (collecting cloth 240) and four compartments 230. However, five or more side surfaces and five or more compartments 230 are used. Alternatively, the housing 200 can be configured by three side surfaces and three compartments 230.

2. Roof material The roof material 300 protects the collection cloth 240 provided in the casing 200 from rainwater, and may be a plate-like one as shown in FIG. 1 or a so-called inclined roof shape. You can also. In addition, when inclining the roofing material 300, it is necessary to be careful not to obstruct the collection of flying salt by the collection cloth 240.

3. Case FIG. 2 is a detailed view showing a side surface 210 and a bottom surface 250 constituting the case 200, wherein (a) is a side view of the case 200 viewed from the side, and (b) is a side view of the case 200 from above. FIG. The outer shape of the housing 200 is composed of at least a side surface 210 and a bottom surface 250 shown in FIG. 2, and a compartment 230 partitioned by a partition wall 220 is provided inside as described above.

(Side)
The side surface 210 is constituted by a thin plate-like member, and a collection window 260 is provided near the center thereof. This collection window 260 is provided by hollowing out a plate-like member, and a mesh-shaped collection cloth 240 is installed here. That is, the wind containing salt can pass through the collecting cloth 240 in the side surface 210, and at this time, the salt adheres to the collecting cloth 240. The collection cloth 240 can be installed on the side surface 210 using a nail or a pin, or can be attached on the side surface 210 using an adhesive or the like.

(Bottom surface)
As shown in FIGS. 2A and 2B, a bottom surface 250 is provided at the bottom of the housing 200. Similar to the side surface 210, the bottom surface 250 is formed of a thin plate-like member, and is provided with a vent hole 250a so that at least one is disposed in a compartment 230 described in detail later. Note that the top surface of the housing 200 facing the bottom surface 250 can be provided with a ceiling surface by the same member as the bottom surface 250. However, the multi-directional flying salt collector 100 has a roof material 300 as shown in FIG. When provided, this ceiling surface can be omitted.

(Partition and compartment)
FIG. 3 is a perspective view of the housing 200 seen through the side surface 210 in order to explain the partition wall 220 and the compartment 230. As shown in this figure, the partition walls 220 are arranged so as to divide the space surrounded by the side surfaces 210, and the spaces divided by the partition walls 220 become compartments 230, respectively. A plurality of compartments 230 are provided in one housing 200. For example, in the case of FIG. 3, the side face 210 is arranged on the diagonal line of the quadrangle in plan view composed of the four side faces 210, so Four 230 are provided.

  As can be seen from FIG. 3, each compartment 230 is a space surrounded by the side surface 210, the partition wall 220, and the bottom surface 250, and includes a collection cloth 240 and a vent hole 250 a. Therefore, the flow of wind containing salt is as follows. That is, the wind that has entered the compartment 230 through the collecting cloth 240 from the outside is blocked by the partition wall 220 and the roofing material 300 (or the ceiling surface) and moves to the vent hole 250a of the bottom surface 250, and this is used as the exit. It flows out again. As a result, the wind containing salt passes only through the collecting cloth 240 facing the direction of the wind, and does not pass through the other collecting cloth 240. That is, the amount of salt collected by the collection cloth 240 is only due to the amount of salt flying from the direction facing the collection cloth 240, so that the amount of salt divided by the flying direction can be accurately investigated. It is.

(Other housing shapes)
As described above, the housing 200 used in the multidirectional salt collector 100 of the present invention is not limited to the four side surfaces 210. 4A and 4B are plan views showing other housing shapes, in which FIG. 4A is a plan view showing a hexagonal housing 200 composed of six side surfaces 210, and FIG. 4B is a plan view consisting of one side surface 210. FIG. 3 is a plan view showing a circular housing 200. FIG. As shown in these drawings, a plurality of collecting cloths 240 are provided, and the collecting cloths 240 are arranged in different directions, and the compartments 230 and vent holes corresponding to the number of the collecting cloths 240 are provided. If 250a is provided, the housing 200 can select various plane shapes. Also, the number of side surfaces 210 constituting the housing 200 can be appropriately designed according to the planar shape of the housing 200. In the case of FIG. 4A, the hexagonal shape has six side surfaces 210, as shown in FIG. In this case, the casing 200 is constituted by one side 210 as a circular shape.
