Description

[0001] Rainwater harvesting apparatus [0002]
The present invention relates to a rainwater collecting device.
As is widely known, climate change due to global warming and / or global environmental pollution creates droughts and floods, which limits the ability to secure adequate drinking water (or drinking water) with conventional water management systems alone.
In order to overcome this water shortage, researches on collecting and storing rainwater have been actively carried out.
The method of collecting rainwater can be classified into a method of collecting rainwater collected on the floor such as roads according to its shape (Patent Document 1), and a method of storing rainwater falling into the air before reaching the ground (Patent Document 2).
As shown in Patent Document 1, the method of collecting rainwater collected on the ground surface (floor) into the water together with various pollutants settled in forests, grasslands, construction sites, agricultural lands, river sediments, roads and industrial sites through rainwater Since it contains a large amount of non-point pollutants, it can be used as water only after undergoing a separate treatment. Therefore, in the conventional technology according to the method of Patent Document 1, as described above, not only a filtration device for filtering nonpoint pollutants contained in rainwater must be applied, but most of them are made of a concrete structure, .
Alternatively, as in Patent Document 2, a method of directly collecting rainwater in the air before coming into contact with a nonpoint source of pollution includes a collecting membrane structure having an open top. The collector membrane of Patent Document 2 is closed by closing the inlet of the main pipe with a fallen leaf or the like, and effective collection of water is not achieved.
Korean Patent No. 10-0756294 Korean Patent No. 10-1344693
The present invention has been made to solve the above-described problems, and it is intended to collect rainwater in the air so as to prevent contact with non-point pollution sources. It is another object of the present invention to selectively collect water only at the time of rainy weather and / or at the time of snowy weather.
In order to achieve the above object, the present invention relates to a rainwater collecting device capable of collecting rainwater in the air, comprising: a conveyance part having a hollow inside and having a drain pipe therein;
A water collecting plate connected to the upper surface of the collecting plate so as to be in fluid communication with the outer circumferential surface of the conveying unit in a radial direction higher than the surface of the soil, And a catching part having a catching line for covering the upper part of the collecting plate; And
And a storage unit disposed at a lower portion of the transfer unit and connected to the drain pipe so as to be in fluid communication.
The present invention arranges a light collecting plate for collecting solar light and converting it into electrical energy at the upper end of the transfer unit.
In addition, the present invention provides a wind turbine rotatable in the feed section for converting wind energy into electrical energy, which is disposed below the condenser so as not to interfere with the rotation of the wind fan.
The present invention is equipped with a storage battery for storing electric power generated by a condenser and a wind fan, and a controller capable of supplying the electric power to the constituent member.
The present invention can arrange the collecting part in multiple stages at different heights on the outer circumferential surface of the conveying part.
Incidentally, the present invention disposes the collecting part at equal intervals around the outer peripheral surface of the conveying part. This not only allows the sunlight to reach the surface of the ground through the clearance between the pans, but also allows collection of rainwater to the pans arranged at the bottom.
The present invention has a net having a dome-shaped mesh structure, and can easily remove foreign matter having a size larger than the pore of the net.
The present invention further includes an electric hot wire to melt snow or ice on the water collecting plate, and the hot electric wire can be driven by a battery or external power.
In addition, the wire net according to the present invention can also incorporate an electric hot wire.
Preferably, the present invention has a first cover member and a second cover member which are symmetrically arranged so as to be openable and closable on a collecting plate having an open top. Such a cover member is opened only in the case of rain and / or snow, so that the seating of the foreign matter and the inflow of the fine dust can be prevented in advance on the collecting plate.
The water collecting plate of the present invention has a semicircular front partition wall and a rear partition wall to ensure a slide for reliable opening and closing of the first cover member and the second cover member.
The front partition wall has a curved rail along the periphery of the inside edge, and a rear partition wall has a curved rail along the periphery of the inside edge.
The first cover member and the second cover member of the present invention are mounted between the rails of the front partition wall and the rails of the rear partition wall so as to be slidable in the vertical direction.
The lower ends of the first and second cover members are provided with a sponge, preferably a PVA sponge. The PVA sponge can open and close the first cover member and the second cover member through a load depending on the water absorption rate.
Stoppers may be individually mounted on the upper end portions of the first cover member and the second cover member to restrict downward movement of the cover member. The stopper can be caught by the left side wall and the right side wall of the collector when the cover member is lowered to prevent separation.
The first cover member is provided with a spring that can be opened and closed according to the degree of absorption of the PVA sponge as described above, and this spring is disposed between the upper end of the first cover member and the right wall of the collector plate.
In contrast, the second cover member also has a spring, which is disposed between the upper end of the second cover member and the left wall of the collector plate.
Here, when the rainwater is dried in the PVA sponge, the spring significantly reduces the load of the PVA sponge, and rapidly lifts the first cover member and the second cover member to the right position through the tension of the spring to close the opening of the collector plate .
Since the first cover member and the second cover member are selectable, an electric hot wire can be embedded in the first cover member and the second cover member.
The features and advantages of the present invention will become more apparent from the following detailed description based on the accompanying drawings.
Prior to that, terms and words used in the present specification and claims should not be construed in a conventional and dictionary sense, and the inventor may properly define the concept of the term in order to best explain its invention It should be construed as meaning and concept consistent with the technical idea of the present invention.
According to the present invention, the present invention is designed to collect rainwater in the air, and thus can store clean rainwater that is not in contact with non-point sources.
The present invention provides accessibility to safely supply in an area where water supply is not smooth and convenience to manage rainwater directly, and it is possible to construct a water supply system with low budget and is structurally simple compared with other systems .
In addition, the present invention provides snow catching effect by preventing the breakage of the water collecting device by melting snow and ice piled on the catching part during the winter season.
The present invention is installed on the ground surface and collects rainwater in the air. The rainwater is collected by separating the at least one collecting part at a predetermined interval, or the collecting part is made of a transparent material to ensure that the sunlight reaches the ground surface.
Incidentally, the present invention can open the cover member only when it has a load absorption rate larger than the tension of the spring, and it is opened only after a certain period of time from the start of the initial rainfall. This results in the effect of not collecting the initial rainwater in the contaminated state.

The rainwater collecting device (1) according to the present invention comprises a water collecting part (100) for receiving rainwater which is installed higher than the ground surface so that rainwater can be collected in the air before the rain water touches the ground surface, And a transfer unit 200 for connecting rainwater collected in the collecting unit 100 to the storage unit 300 so as to be in fluid communication with the storage unit 300.
One or more pockets 100 are provided radially around the conveying part 200 which is arranged in the vertical direction from the ground, and the collecting part 100 and the conveying part 200 are connected in fluid communication.
Specifically, the water collecting part 100 includes a water collecting plate 110 having an open upper part, a connecting part 120 connecting the water collecting part 100 and the conveying part 200, and a connecting part 120 for covering the upper part of the collecting plate 100 (130).
The connecting portion 120 is a constituent member that can be coupled to the outer circumferential surface of the transfer portion 200 and includes a guide pipe 121 (see FIG. 2) And the transferring part 200. [0051] That is, the guide pipe 121 is a path for guiding rainwater collected on the collecting plate 110 to the main drain pipe 210 (see FIG. 2) of the transfer unit 200.
The water collecting plate 110 is structured such that the upper part thereof is opened so as to ensure efficient collection of rainwater. The foreign substances such as leaves and paper are accumulated on the collecting plate 110, So that the upper portion thereof is covered with the wire netting 130 so as not to be closed. As is well known, the net 130 is made of a mesh structure, which allows the rainwater to pass through the pores, while filtering out foreign matters such as leaves and paper larger than the pores.
Preferably, the strip 130 is dome-shaped. The foreign substances that can not pass between the pores of the sieve 130 are placed on the dome-shaped sieve 130 so that the foreign substances can be slid from the outer surface of the sieve 130 to the surface without additional external force.
The collecting plate 110 may be made of various materials such as metal, wood, and synthetic resin, and is preferably made of a transparent material so that the sunlight can reach the ground surface. In addition, the water collecting plate 110 may be exposed to sunlight for a long time to agitate the water collecting plate to cause cracking or foreign matter on the surface of the water collecting plate 110. In addition to improving the releasability of the water collecting plate 110, Can be coated with Teflon to provide water repellency through a low coefficient of friction. In addition, the collecting plate 110 may be coated with titanium dioxide (TiO 2 ) having a self-cleaning function to decompose the surface organic matter.
As shown in the figure, the transfer unit 200 is a structural member interposed between the collection unit 100 and the storage unit 300 to connect the storage unit 300 and the storage unit 300 in fluid communication.
The transfer unit 200 has a hollow hollow shape, and has a main drain pipe 210 (see FIG. 2) extending in the longitudinal direction.
In addition, the transfer unit 200 has a condenser plate 220 at the upper end thereof. The light collecting plate 220 is a constituent member for collecting solar light. The light collecting plate 220 collects sunlight through the light collecting plate 220 and converts light energy into electric energy, thereby generating electricity required for the rainwater collecting apparatus 1 of the present invention. .
The transfer unit 200 may further include a wind fan 230 rotating in a horizontal direction at an upper end thereof. In other words, the wind-driven fan 230 is rotatably installed on the axis of the conveyance unit 200 on which the condenser plate 220 is installed. As is well known, the wind-driven fan 230 can rotate by engaging with the wind-driven fan 230 to generate electricity by operating a generator (not shown). The rainwater collecting apparatus 1 according to the present invention can reserve the converted power through the condenser 220 using solar light and the wind power fan 230 using wind power as described above. The reserved power can be used as a power source for the constituent members necessary for the electricity supply of the present invention. Of course, such a power source can be developed and used by itself, and the external power source can be applied as it is.
The transfer unit 200 has a storage unit 300, for example, a reservoir tank, at a lower end thereof.
The storage unit 300 is a component that stores rainwater collected in the air through the collection unit 100 as shown in FIG. In other words, the storage unit 300 can supply or transfer the water stored therein through the separate piping to the rear end facility.
1, the rainwater collecting device 1 of the present invention includes a storage part 300, a transfer part 200, and a collecting part 100, similar to a tree structure composed of roots, stems and leaves. It can maintain rainwater tree form.
Such a tree-shaped rainwater collecting device (1) has a natural-friendly shape even if it is installed in a natural green space and an open space, so that rainwater and snow can be collected without damaging the surrounding scenery.
Fig. 2 is a partial cutaway view of the rainwater collecting device of Fig. 1;
2, the rainwater collecting apparatus 1 according to the present invention includes a storage unit 240 for storing solar power converted into electric energy by means of a light collecting plate 220, . Of course, the battery 240 may also rotate the wind power fan 230 with wind power to reserve the converted power. The controller 250 allows the power generated by the condenser 220 and the wind-up fan 230 to be stored in the battery 240, and can supply necessary power according to the response of the thermometer, for example. For reference, the battery 240 and the controller 250 are disposed higher than the collecting part 100 to prevent contact with rainwater.
Here, the electric wiring connecting the condenser plate 220, the wind fan 230, the battery 240, and the controller 250 is well known to those skilled in the art and is excluded to facilitate a clear understanding of the present invention do.
The present invention can include an electric hot wire 140 to collect snow while reducing the load applied to the catch part 100 by a snow load when snow is accumulated on the wide catch part 100. [ As shown in the drawing, the hot wire 140 is installed in the catching part 100, and can collect snow melt water through a melting process of melting the snow accumulated on the catching wire 130.
In addition, the present invention embeds an electric hot wire (not shown) in the wire net 130 to quickly melt the snow on the wire net 130. The power source of the electric hot wire may be supplied from the battery 240 or an external power source.
The rainwater or the cooling water is collected by the collecting plate 110 of the collecting part 100 and is guided to the drain pipe 210 of the transfer part 200 along the guide pipe 121 of the connecting part 120, And is collected vertically downwardly along the bottom surface 210 and collected in the storage unit 300. Accordingly, the transfer unit 200 is connected to the storage unit 300 in fluid communication with the storage unit 300 to guide the rainwater to the storage unit 300 through the drain pipe 210.
FIG. 3 is a plan view of the rainwater collecting apparatus shown in FIG. 1. As shown in FIG. 1 and FIG. 2, a plurality of collecting plates 110 are formed in multiple stages, preferably along the longitudinal direction of the conveying unit 200, Are stacked in two layers.
The water collecting plate 110 is radially arranged at equal intervals, for example, four water collecting plates 110 along the peripheral surface of the conveying unit 200. In order to improve the collection efficiency, as described above, the four collection plates disposed at the lower end are arranged between the four collection plates disposed at the upper end. When viewed from above, the four collection plates are arranged along the outer peripheral surface of the transfer part 200, To maximize the catchment area.
FIG. 4 is a perspective view showing another example of a collecting part to be applied to the rainwater collecting device according to the present invention.
In the present invention, rainwater is collected in the air through a collecting plate 110 having an open top, and it is inevitably necessary to allow foreign matter to be unnecessarily accessed through the collecting plate 110 having an open top.
Accordingly, the rainwater collecting device 1 of the present invention can open and close the collecting plate 110 by means of the cover members 113 and 114 which can be opened and closed on the collecting plate 110 opened on the top as shown in FIG.
The water collecting plate 110 has a semicircular front partition wall 111 at one edge and a semicircular rear partition wall 112 at the opposite edge.
The front partition wall 111 has a rail 111a curved along the inner periphery. Correspondingly, the rear compartment wall 112 also has a rail 112a that is curved around the inner edge.
The side portion of the first cover member 113 is interposed between the rail 111a of the front partition wall 111 and the rail 112a of the rear partition wall 112 and can slide along the rails 111a and 112a . A sponge 115 is provided at the lower end of the first cover member 113. On the other hand, the first cover member 113 has the spring 116 at the upper end thereof. The stopper 113a protrudes downward from the upper end of the first cover member 113. The stopper 113a extends over the left wall of the collecting plate 110 when the first cover member 113 descends, The first cover member 113 can be prevented from being separated from the second cover member 112a.
Specifically, the spring 116 is fixedly coupled between the upper end of the first cover member 113 and the right wall of the water collecting plate 110, thereby assisting the sliding of the first cover member 113.
The side portion of the second cover member 114 is interposed between the rail 111a of the front partition wall 111 and the rail 112a of the rear partition wall 112 and can slide along the rails 111a and 112a . A sponge 117 is provided at the lower end of the second cover member 113. On the other hand, the upper end portion of the second cover member 114 is provided with the spring 118. 5A) protruded downward from the upper end of the second cover member 114. The stopper 114a is provided on the right wall of the collector plate 110 when the first cover member 113 is lowered It is possible to prevent the second cover member 114 from separating from the rails 111a and 112a.
Specifically, the spring 118 is fixedly coupled between the upper end of the second cover member 114 and the left side wall of the collecting plate 110, thereby assisting the sliding of the second cover member 113.
Here, the sponges 115 and 117 may be made of a material having water resistance and weather resistance, specifically, PVA (Poly Vinyl Alcohol). The PVA sponge is not only easy to shape but also has a property of curing during drying and gradually absorbing moisture upon contact with water. The absorption rate has about 1,000 to 1,200% of the sponge volume. By using this characteristic, the load of the PVA sponge in the dry state is smaller than the tension of the spring to keep the spring in the contracted state, while the load of the PVA sponge in the functional state becomes larger than the tension of the spring, Thereby opening the cover member. The sponges 115 and 117 are not limited to the PVA material but may be made of a material capable of absorbing moisture (for example, rainwater, ice water) or a material having a moisture-absorbing property.
It is possible to embed an electric hot wire in the cover members 113 and 114 in order to rapidly dissolve snow accumulated on the cover members 113 and 114 in winter. Of course, an electric hot wire may be additionally incorporated into the wire netting 130.
5 schematically illustrates an operation state of the collector plate 110 having the cover members 113 and 114 which can be opened and closed as shown in Fig.
5A is a view showing a closed state of the cover members 113 and 114 arranged symmetrically on the upper part of the collecting plate 110. FIG. 5A does not contain moisture in the sponges 115 and 117 and the cover members 113 and 114 can be pulled upward along the rails 111a and 111b through the tension of the springs 116 and 118 to maintain the closed state.
Fig. 5B is a view showing the open state of the cover members 113 and 114 in a rainy season. The rainwater is gradually absorbed by the sponges 115 and 117. When the sponges 115 and 117 sucking rainwater become heavier than the tension of the springs 116 and 118, the cover members 113 and 114 gradually descend along the rails, Is exposed to the outside. The rainwater can be collected through the collecting plate 110 while the cover members 113 and 114 are opened.
The cover members 113 and 114 are lowered by the load of the sponges 115 and 117 and the falling distance is limited through the stoppers 113a and 114a. Therefore, the cover members 113 and 114 do not separate from the rails 111a and 112a (see FIG. 4), and the sponges 115 and 117 are dried.
In addition, since the cover members 113 and 114 can be opened only when the rainwater is absorbed by the sponges 115 and 117 beyond the allowable tension of the springs 116 and 118 as described above, during the initial time of absorbing the rainwater to the sponges 115 and 117, The members 113 and 114 are kept closed. This is because it opens after a certain period of time at the beginning of the initial rainfall and delays the opening time, thereby not collecting the initial rainwater in the contaminated state.
FIG. 6 is a view illustrating the construction of a rainwater collecting device and a water storage tank according to the present invention. A plurality of rainwater collecting apparatuses 1 are connected to the drain pipe 210 (see FIG. 2) through pipes and are in fluid communication with the large water storage tank 400. The plurality of rainwater collecting apparatuses 1 are installed on the ground surface continuously in a plurality of rows. However, the water collecting area is increased to maximize the water collecting efficiency, and the rainwater to be used as the drinking water can be smoothly taken. The arrangement position of the rainwater collecting device (1) can be modified into various forms depending on the installation place and installation purpose.
While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not to be limited to the details of the illustrated embodiments, It is obvious that the modification and the modification can be made by the person having.
It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
