Description

mist collector

The invention relates to a fog collector for absorbing moisture from incoming ambient air.

It is well known that drinking water is very scarce in some regions of the world due to climatic conditions. For this reason, so-called fog traps or fog collectors have been used for several years in various third world countries. These can collect the water molecules in the air and provide the local people with drinking water via an associated transport system.

From the German patent application DE 10 2010 003 953 A1, for example, such a mist collector is known, which has a formed as a flow-through textile element deposition structure and a support structure for this purpose.

However, there is usually a high wind speed at the places where the fog is highest, which means that conventional fog collectors are destroyed after a short period of use. The tissue responsible for collecting the drops of water is literally torn due to the strong wind, which makes maintenance and repair time-consuming and expensive.

Furthermore, a fog collector is known from international patent application WO 2014/153093 A1, in which a holding structure for pivotable support of a collector surface is provided. The collector surface can be made of nylon, polymer, metal, mesh, fabric, silicone, or any other known and conventional material that allows it to be deformed at least locally into given geometries. The collector surface may be attached to a support frame, which is pivotable relative to the rest of the support structure. On the collector surface energy collectors can be partially installed, which can be used to collect energy.

This embodiment of a fog collector offers a number of advantages, in particular since the collected electrical energy is also used for electrical pivoting of the holding frame can be used, but is also relatively expensive. Thus, in particular, the collector surface can be made of a dimensionally stable, particularly tearable material, however, the cost of a collector surface with a high yield of collected water molecules are relatively high, while a reduction in the cost comes at the expense of yield or at the expense of dimensional stability and tear resistance ,

It is therefore an object of the invention to provide a mist collector which is robust against high wind speeds and at the same time cost effective to manufacture and maintain.

The object is achieved according to a first aspect of the invention with the features of independent claim 1. The subclaims relate to advantageous embodiments of the invention.

An inventive fog collector for receiving moisture from incoming and flowing through ambient air having at least one carrier grid Sammelnetz complex and a support structure to which the at least one carrier grid Sammelnetz complex is added, wherein the carrier grid collecting network complex at least one collecting network and a carrier grid for mechanical stabilization, wherein the at least one collecting network and the carrier grid are connected at least partially. Consequently, the mist collector is equipped with a collecting network arranged in a supporting structure for separating the moisture and has an additional carrier grid for the mechanical stabilization of the collecting network, which may be connected thereto at least in certain areas. This ensures that the collection network is stabilized and no longer ruptures at excessive wind speeds.

Thus, the collection network can be designed for an optimized yield, without having to take into account its dimensional stability and tear resistance, while the support grid can be optimally designed to stabilize and secure the collection network. For both the collection network and the carrier grid, known commercially available structures can be used that are relatively inexpensive to obtain and their respective ones are based on the above objective of high yield of water molecules. len and high tensile strength optimized properties can be easily combined with each other.

In one embodiment of a fog collector according to the invention, the carrier grid can be connected to the collection network in a planar manner, which increases the overall stability compared to large wind forces.

Furthermore, it can be provided that the carrier grid extends over the entire surface of the collecting network, so that stabilization of the collecting network can be ensured over its entire area.

In an alternative embodiment of a fog collector according to the invention, the carrier grid may be located on that side of the collecting network which predominantly forms the leeward side of the fog collector. In this conceivable embodiment, the carrier grid collecting network complex is formed at least in sections in several layers in the manner of a sandwich comprising at least one collecting network and a parallel thereto arranged carrier grid. As a result of an arrangement of the carrier grid in the assembled state of the fog collector (predominantly) on the lee side of the fog collector, the collection network is pressed by the incoming air surface against the carrier grid, so that overall results in a uniform force distribution, and the connection points of the carrier grid with the collection network not over an acceptable level be claimed.

In this case, the carrier grid can be formed as a wide-meshed plastic grid, in particular as a so-called geogrid. Such geogrids are used in particular in road or gardening and landscaping to stabilize the soil or gravel layers. They are usually made of plastic and available inexpensively in large quantities. Advantageously, the geogrid available on the market under the name Tensar TriAx T190L is used in this connection. Said geogrid is made of a plastic sheet, in particular of a polypropylene, inter alia by stretching and has a hexagonal basic shape with triangular geogrid openings. The hexagon distance, ie the distance between two parallel sides of the hexagons, is about 120mm. A more detailed description of the mentioned lattice like other possible lattices can be found in the German See translation of European Patent EP 1 534 898 B1, DE 603 13 978 T2, there in particular in Figures 4 and 5. The disclosure of the cited documents is incorporated by reference in the present application. The mentioned geogrid is characterized in particular by its high dimensional stability even under lateral tension, so that it does not deform even under high stress, in particular at the connection points to the support structure. Of course, other grids with deviating distances or geometries such as square or diamond-shaped opening shapes are conceivable.

In an alternative embodiment, as a carrier grid, for example, a grid can be used, which is commercially available under the name Terram TURFPROTECTA. Such a grid shows a hexagonal basic shape of the grid openings and is formed from a HD polyethylene. It is available with mesh sizes of 22 resp. 25 (longitudinal) and 27 resp. 29 (crosswise).

In particular, a wide-meshed grid is understood to mean a grid which has a larger mesh size than the associated collection network.

Furthermore, the carrier grid / collecting network complex, in particular the carrier grid, of a fog collector according to the invention can be connected to the supporting structure via elastic holding elements.

The elastic holding elements may preferably be designed as a rubber expander, which on the one hand a certain basic elasticity in the system immanent training and on the other hand, an overload protection can be created, which essentially consists in that tear at excessive windfall rather the rubber expander and thus created breaking points be damaged than the comparatively expensive collecting network or the carrier grid or the support structure. A possible replacement of the rubber expander is quick and inexpensive to implement. Of course, other retaining elements such as stainless steel springs, especially stainless steel tension springs, cable ties, metal brackets or a combination of cable ties and metal brackets, conceivable. In a further conceivable variant of the invention, two carrier grid / collecting network complexes, in particular two carrier grid, can run in two parallel, spaced-apart planes. With such an arrangement, it is possible to recapture the water droplets blown out by the wind from a first carrier grid / garbage net complex in a second carrier grid / garbage net complex, thereby maximizing the yield of the collected water.

A mist collector according to the invention may further comprise below the collecting nets a drip gutter for receiving collected water, the drip gutter between parallel legs of mounting brackets, which may be connected on the one hand with the carrier grid / collecting network complex, in particular with the carrier grid, and on the other hand with the support structure , can be arranged.

This arrangement has the advantage that the drip gutter is able to move with the carrier grid collecting network complex in the event of wind-induced elastic deformation and deflection and thus maintains its relative position to the at least one collecting network in order to reliably collect the collected water from the carrier grid collecting network. Complex recording.

Such a drip gutter may be formed from a plastic such as poly-ethylene and / or also from a stainless steel.

In an advantageous embodiment of the invention, the mounting bracket can be connected via elastic holding elements with the support structure, whereby the elasticity of the system is not affected.

Furthermore, the holding structure may have an anchoring arrangement for releasable anchoring of the support structure to the substrate. The solubility of the anchoring arrangement has the advantage that the fog collector can be relatively easily implemented, for example, if the main wind direction has changed seasonally or if other circumstances make it necessary to implement the fog collector.

A further advantageous application of a releasable anchoring arrangement has to do with the installation of several mist collectors, for example three Fog collectors, proven in the composite. So they can be arranged in a so-called 135 angular degree position relative to each other for the duration of a first season, ie in such a way that two adjacent fog collectors form an angle of about 135 ° between them. As a result, for example, three different orientations of the collectors are given to the wind direction. Each collector is associated with a water collecting container, which serves to determine the collected water.

In a further step, the best of the (for example three) different orientations can be determined on the basis of the determined yield quantity of the water collected during the season. In the next season, the rest of the collectors are then implemented in a further step by means of the releasable anchoring arrangement, so that they are oriented parallel to the collector with the highest water yield and consequently the best orientation.

By means of this comparatively simple arrangement and the associated method for determining the best alignment of the collectors, a simple and inexpensive determination and implementation of an optimized alignment of the collectors is provided.

The anchoring arrangement may in particular comprise a base plate with a connection point provided for connecting the support structure and a number of pin-shaped anchoring elements. Thus, the elongated anchoring elements may comprise, for example, pegs. These can be plugged or hammered for anchoring with one end through corresponding receiving openings on the base plate into the ground. Furthermore, the anchoring elements may have at their other end a rear grip element, for example a thickening, a head or the like. The latter engages in the inserted state, the base plate and fixed in this way the associated support structure on the ground. The design of the anchoring elements as pegs or the like is particularly suitable for attachment to earthy substrates.

The connection point can comprise, for example, a fastening clamp or the like, by means of which the support structure can be detachably fastened to the anchoring structure. Alternatively, an anchoring arrangement may be provided which comprises two or more anchoring arms, which are formed for example by Erdnägel or the like. Furthermore, the anchoring arrangement comprises a connection point for connecting the support structure. The connection point can also include in this embodiment variant, for example, a mounting clamp or the like, by means of which the support structure can be releasably attached to the anchoring structure. Alternatively, the connection point may also comprise a cladding tube or the like, which has a slightly larger inner diameter than a corresponding element of the support structure, so that it can be inserted into the cladding tube.

The anchoring arms can be integrally formed with the connection point or connectable to this. In an embodiment as pegs, the anchoring arms may protrude, for example, through corresponding openings at the connection point and be oriented substantially horizontally for optimal anchoring in the assembled state. For additional or alternative stabilization and anchoring the anchoring arrangement may also have a base plate. This base plate can also be formed by a grid-shaped structure. The anchoring arms and / or the base plate can / can be placed in this embodiment for anchoring to the ground or used in a corresponding hole in the ground and covered with soil, so that only the connection point protrudes from the landfill. This embodiment allows the detachable anchoring of the fog collector on loose surfaces such as sand, gravel or the like.

To increase the stability of the fog collector can be provided regardless of the specific configuration of the anchoring arrangement to provide additional substantially horizontally extending retaining struts and diagonal support struts.

Furthermore, a rain collecting container, in particular a rain collecting tray, can be attached to the supporting structure, which allows an increased water yield in rain, for example in the monsoon season, compared to the collecting network. This can be releasably attached to the support structure as needed, if rains are to be expected. The invention will be explained in more detail with reference to selected figures. They show schematically:

Figure 10A shows a detail of Figure 10. FIG. 1 shows, in one exemplary embodiment of the invention, a first possible variant of a fog collector 100 according to the invention. FIGS. 9 and 10 also show alternative embodiments of a fog collector 100, which delimits itself from the variant of FIG. 1 in the following differences and also in combination with two is set up further collectors.

The supporting structure of the collector 100 formed from tubular posts 1 and struts 1 'is easily recognizable in all embodiments. In the example of FIG. 1, this is connected to retaining rails 2 located on the ground, which in turn are embedded in a foundation 3 laid in the ground. screwed here. In this case, the retaining rails 2 may be formed such that in conjunction with a through-bolt and the support structure, a hinge can be realized, whereby the fog collector can be transported after assembly in an upright position (not shown here). Of course, other types of anchoring in the ground are conceivable, for example, the use of a cast-in cladding tube whose inner radius is slightly larger than the outer radius of the post 1, so that they are inserted into the cladding tube from above and there again can be easily removed. In this case, the tensioning cables 4 likewise shown in the figure could possibly be omitted.

Also, separate anchoring structures can be provided, which allow a releasable anchoring to a substrate U (without providing a foundation). Thus, as shown in Figures 9 and 10, the support structure formed from posts 1 and struts 1 'have an anchoring arrangement for releasably anchoring the support structure to the substrate U. The solubility of the anchoring arrangement has the advantage that the fog collector 100 can be easily installed and implemented comparatively easily if required, for example, if the main wind direction and thus the direction of flow of the ambient air has changed significantly.

In particular, as shown in FIGS. 9 and 9a, the anchoring arrangement may comprise a base plate 20 having a connection point for connecting the support structure and a number of pin-shaped anchoring elements 22 (shown in dashed lines in the detail view of FIG. 9a) in the form of pegs Anchoring can be beaten into the ground at one end by means of corresponding receiving openings 21 on the base plate 20 and at the other end by a rear grip element. For example, have a thickening 23 in the form of a nail head. The latter engages in the inserted state, the base plate 20 and fixed in this way the support structure connected to the base plate 20 on the substrate U. The design of the anchoring elements as pegs or the like is particularly suitable for attachment to earthy substrates.

The connection point is formed in the embodiment of Figures 9 and 9a as a combination of a mounting clamp 1 1 (see also Figure 8) and a tie 1 1 a. The tie 1 1 a fixes a horizontal strut 4 ", which is used in the embodiment variant of Figures 9 and 10 for stabilizing the fog collector 10, on the base plate 20. The mounting clamp 1 1, however, attached one of the support struts 4 'of the fog collector 10, the at the embodiment variant of Figures 9 and 10 is used as an alternative to the tension cables 4 for stabilizing the fog collector 10.

Alternatively, an anchoring arrangement, as shown in FIG. 10, may be provided, which comprises two or more anchoring arms 22 ', which are arranged substantially horizontally in the assembled state. In the embodiment shown, these are particularly advantageously designed as pegs, which can be inexpensively and easily connected to a cladding tube 24 functioning as a connection point by being inserted through corresponding openings on the cladding tube. Furthermore, the anchoring arrangement comprises the already mentioned connection point for connecting the support structure. In this case, the inner recess of the cladding tube 24 can also be used to connect a post 1 of the support structure as well as for receiving additional mounting clamps 1 1 (see also Figures 8 and 10), both a support strut 4 'and a horizontal strut 4 "of the fog collector 10 with can connect to the cladding tube 24. An inserted into the cladding tube 24 post 1 can be additionally secured with a connection clamp.

For additional stabilization and anchoring, the anchoring arrangement, as shown, also have a base plate 20 '. This base plate 20 'may also be formed by a lattice-shaped structure. The anchoring arms 22 'and the base plate 20' can be placed in this embodiment for anchoring to the ground or used as shown in a recess 25 and covered with soil, so that only the cladding tube 24 protrudes as a connection point from the landfill. This embodiment enables the detachable anchoring of the fog collector on loose surfaces such as sand, gravel or the like.

In order to increase the stability of the fog collector 10, it can be provided with tensioning cables 4 (see FIG. 1) or alternatively or additionally with support struts 4 '(see FIGS. 9 and 10), regardless of the specific embodiment of the anchoring arrangement, which may additionally be provided with horizontal struts 4 This embodiment is particularly suitable if several, for example, two or three collectors are placed together instead of a single fog collector, since the two adjacent collectors additionally stabilize.

As already indicated, in FIGS. 9 and 10, three mist collectors are shown assembled to one another. This specific arrangement has proven itself for the simple determination of the best alignment of the collectors, where appropriate, more than three or only two collectors can be set up and used in the manner described below.

Thus, in a first step, the collectors 100 will be arranged relative to each other for the duration of, for example, a first season in a so-called angular position with a predetermined intermediate angle of, for example, 135 ° (see FIG. such that two adjacent mist collectors 100 enclose between them an angle of about 135 °. As a result, for example, three different orientations of the collectors are given to the wind direction. In an arrangement with more or less than three collectors, the selected intermediate angle can be adjusted accordingly.

Each collector 100 is associated with a water collecting container W, which serves to determine the collected water.

In a further step, the best of the three different orientations can be determined on the basis of the determined yield of the water collected during the season. In the next season, the rest of the collectors are then implemented in a further step by means of the releasable anchoring arrangement, so that this be oriented parallel to the collector with the highest water yield and consequently the best orientation (see Figure 9).

By means of this comparatively simple arrangement and the associated method for determining the best alignment of the collectors, a simple and inexpensive determination and implementation of an optimized alignment of the collectors can be provided.

In the example shown in FIG. 1, two variants of arrangements of collecting network 6 and carrier grid 8 are suspended by means of clamping elements 5, in this case rubber expander. In FIG. 1, a simple position of such an arrangement (carrier grid collecting network complex) is shown on the left ) from collecting network 6 and carrier grid 8, whereas on the right a sequence of two corresponding arrangements (carrier grid collecting network complexes) is shown. Below the collecting nets 6 is in each case a drip trough 7 for receiving the dripping from the collecting networks 6 water available. This continues into an associated water catchment W.

Further details of the invention will be explained in more detail with reference to the following figures.

Figure 2 shows in an enlarged detail of Figure 1 in particular the conditions in the lower part of the fog collector 100. Well recognizable again is the single-layer design of the combination of collecting network 6 and carrier grid 8 on the left side of the collector 100 and the two-layer design of said combination on the right side of the collector 100; correspondingly wider in this case, the drip gutter 7 'is selected. The two-ply formation of the fog collector 100 can be achieved, for example, as shown by the fact that in each case a support grid 8 is received by the end pieces of a rubber expander or an alternative clamping element 5, which is placed around a post 1 around, so that the support grid 8 and they are the collecting networks 6 substantially spaced from each other by the diameter of the associated post 1 formed. For a better understanding, the subfigure 2A shows an enlarged detail of the carrier grid 8 and the collective grid arrangement 6, which are connected to one another over their entire area. The collective networks 6 may be, for example, the following types of networks (in brackets is the commercial use of the networks): - Raschelnetz PP - (Schattiernetz)

- shading net HDPE - (shading net)

- Hail protection net HDPE - (hail protection and paintball net)

- 3-dimensional 3DEA spacer fabric (water separation)

- ENKAMAT 7220 PA6 - (erosion protection)

Nubbin fabric type F-20200/14 PES - (not yet an industrial application)

- Antigranizio 5x4 - (shading and hail protection net)

- Mosquitera 6x6 - (mosquito protection)

The mentioned network types are already marketable from other applications and thus available at displayable prices. Thus, by combining two marketable products - namely, the geogrid and the various types of collective nets - advantageous functionality of combining both products can be achieved in a completely new application.

The collecting networks can also be multi-layered, in particular double-layered, arranged on a carrier grid (sandwich arrangement).

Also clearly visible in the lower part of Figure 2 is the formation of the carrier grid 8, which serves for the mechanical stabilization of the arrangement and prevents the collecting nets 6 tear at excessive wind speeds. In the example shown, a so-called Tensar TriAx geogrid is used as the carrier grid 8. It is connected to the collecting network 6 areally, wherein 6 methods such as gluing, welding or even a connection by means of cable ties or metal clamps mounted with Zaunringzangen use for planar connection of the carrier grid 8 with the collecting network. The connection of the struts 1 'and the post 1 with the combination of carrier grid 8 and 6 collective network can be done as shown by, for example, designed as a rubber expander clamping elements 5 are wrapped around the posts or the struts 1 and with hooks or other fasteners in the carrier grid 8, for example, be hung in its mesh or in specially prepared holes in the nodes at its edge. The advantage of using rubber expanders is that on the one hand a certain basic elasticity can be inherently formed in the system and on the other hand an overload protection can be achieved. will create, which consists essentially in that tear too much wind uptake rather the rubber expander than the comparatively expensive collecting network 6 or carrier grid 8 or the support structure 1 and 1 'takes damage.

The drip channel 7 and 7 'is arranged in the lower area of the collecting nets 6, that a piece of the collecting network 6 or carrier grid 8 still from the top into the upwardly open drip tray 7 and 7' protrudes, so that falling drops can be reliably captured. In the example shown, the drip gutter 7 and 7 'with a combination of mounting brackets 9 and rubber expanders with the support grid 8 and a horizontal strut 1' of the support structure of the fog collector is connected. In this way, the drip gutter 7 and 7 'with a wind-induced elastic deformation and deflection of the support structure with the carrier grid-collecting network complex move and thus maintain their relative position to the at least one collecting network to continue the collected water reliably from the carrier grid Collecting network complex.

Figure 3 shows details of the connection of drip gutter 7 and the support structure of the fog collector. A lateral view is shown in FIG. 3A and a front view of the drip-water channel 7 in the connection region between a strut 1 'and a post 1 is shown in FIG. 3B. Well recognizable is the combination of collecting network 6 and carrier grid 8, which is held on the support 1 grid 8 in the upper region of the figure by means of rubber expander.

Also clearly visible in the figure is the formation of a mounting bracket 9, which is formed in the example shown so that it shows a V-shaped basic shape, wherein the V-shaped basic shape is extended by two parallel legs, which bent at its ends hook-shaped are. The mounting bracket is passed through the support grid 8 and clamped on the formed at the ends of the legs hook on another rubber expander with a horizontal strut 1 '. Between the legs of the mounting bracket 9, a substantially U-shaped drip tray 7 is arranged, which is prevented by means of two bolted to the legs of the bracket 9 cable clamps 10 from slipping down. In Figure 3b well recognizable beyond the mounting clamp 1 1, which is the post connects with the horizontal strut. Indicated in FIG. 3 b is the sloping bottom of the dripping-water channel 7 sloping down to the right.

In the same way as the drip gutter 7 and 7 'can be used and attached as an additional or alternative element a rain catcher in the form of a rain drip tray 26 (see Figure 9), which serves in the monsoon season for collecting rainwater. The rain collecting tray 26 is also connected to a water collecting vessel W and allows an increased water yield in the monsoon season compared to the collecting net in combination with the drip gutter 7 and 7 '. It may for example be formed of polyethylene sheets or films and between the posts 1 and the support struts 4 'are arranged (see Figure 10).

In this case, the already known in connection with the drip gutter 7, 7 'known clamping elements 5, via which the rain drip tray 26 both with the drip gutter 7, 7' and with, for example, the tension cables 4 or the support struts 4 'see. Figure 9) can be connected. Furthermore, additional support posts 27 can be used to increase the stability and to ensure a secure arrangement of the tub 26.

FIG. 4 shows in subfigures A (lateral view) and B (front view) a variant of the invention in which the combination of carrier grid 8 and collecting net 6 is double-formed, as can be clearly seen in FIG. In this case, the two collecting nets 6 and of course also the two carrier grids 8 extend in parallel vertical planes and are substantially spaced around the diameter of a post 1. In the example shown in Figure 4a, the mounting bracket 9 'is designed with a W-shaped basic shape, otherwise formed analogous to the embodiment shown in Figure 3a. Consequently, the drip gutter 7 'is designed such that it can accommodate both spaced structures.

Figure 5 shows a perspective view of an angled screen plate 12 for coarse filtration of the resulting dripping water. It is inserted into the drip gutter 7, 7 'and screwed for fastening by means of the screw holes formed in its upper part 13 with the lateral end of the drip gutter 7, 7'. The screen plate 12 is formed of stainless steel A2 and has a hole size of 1, 5 to 3 mm, in the shown Example, the screen plate 12 is bent by the angle 20 °. By the standing insertion of the screen plate 12 in the drip gutter 7, 7 'can be achieved that with a possible contamination of parts of the screen plate 12, the water level in the gutter increases until still free areas of the screen plate 12 can be achieved and at Large accumulating amounts of dirt still a reliable screening effect can be achieved without the drip gutter 7, 7 'overflows.

FIG. 6 shows a possible embodiment of a drip channel 7, 7 ', which has a central outlet; Accordingly, the drip gutter 7, 7 'is also designed such that its bottom drops from both sides towards the central outlet 14; in Figure 6a is located in a detail of the drain 14 located at the outlet 14. Good recognizable in Figure 6a of the filter 16 used, which in the present example of a stainless steel wire mesh, which is welded to the drip gutter 7, 7 ', is formed.

Figure 7 shows an example of a possible configuration of rubber expander 5, which are wrapped around a post 1 and are passed through the support grid 8. In this case, the support grid 8 is no longer on stainless steel hooks with the rubber expander in combination, but the rubber expander is threaded through the support grid 8 and merged in the area of the post 1 by means of a quick release 17 to form a loop. The quick release 17 has the advantage of easy adjustability of the voltage of the collecting networks. 6

Figure 8 shows an exemplary connection clamp 1 1, which serves to connect the posts 1 with the horizontal cross braces 1. For this purpose, the connecting clamp 1 1 shows a substantially U-shaped portion formed for articulated connection of the transverse strut 1 ', which is penetrated by a guided through a slot screw 18. Further, the connection clamp 1 1 for clamping connection with the post 1 to a section with O-shaped structure, which can be clamped by means of the two screws 19 with the post 1. In this way, a simple height and lateral adjustability of the combination of posts 1 and struts 1 'can be achieved.

FIGS. 9 and 10 show, as already explained, further variants of a fog collector 100 with an anchoring arrangement for the detachable anchoring of the fog collector 100 on the underground U (as already described above) and with a smaller height dimension (so-called grid dimension) than the embodiment variants of FIGS. 1 to 8. Furthermore, in these variants additional supporting struts 4 'and horizontal struts 4 "are used instead of supporting cables 4. In the variants shown Of course, however, it is also conceivable to provide a single mist collector or a group with more or less than three mist collectors.Furthermore, in connection with Figure 9, a rain catcher 26 is shown, which allows increased water yield in heavy rainfall ,

Due to the high number of identical parts used in the construction of the support structure and the anchoring structure and by the use of known and commonly available components, a cost-effective and easy to build and maintain fog collector can be provided, which also allows a secure water supply.
