BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water intake system, and more particularly, to a water intake system capable of sampling a sample from a lake or a river.

Analysis of fresh water and seawater in rivers, lakes, and oceans is necessary to manage the underwater environment and manage water resources such as rivers, lakes, and oceans.

For example, in rivers such as eutrophicated lakes, slow-flowing rivers, and urban areas, algae may proliferate depending on growth conditions. In particular, when drought or high temperature and high humidity are persistent, green tides are likely to occur in rivers and rivers. These green algae can cause problems in the ecological environment.

In addition, wastewater generated from homes and factories can cause water pollution if they enter rivers. In the rainfall and flood season, the flow rate increases and various pollutants are likely to enter the river.

Green algae and water pollution can vary depending on weather conditions such as drought and heavy rainfall. In order to prevent water pollution and to manage water resources, it is necessary to collect freshwater or seawater samples and analyze them. Conventionally, the water collecting apparatus for sample collection has a complicated structure and requires a high cost at the time of purchase. Therefore, it is important to develop a water intake system that is simple in structure and requires a small cost to manufacture.

Hereinafter, an embodiment according to the present invention will be described with reference to Figs. 1 and 2. Fig.

FIG. 1 is a perspective view showing a watering apparatus 10 according to a first embodiment of the present invention, and FIG. 2 is a view showing a state in which a cap 700 is separated from a catching jaw 200 in FIG.

1 and 2, a first embodiment of a watering apparatus 10 according to the present invention includes a storage container 100, a catching jaw 200 disposed on one side of the storage container 100, a storage container 100, A rope 400, a cap 500, and a weight 600 disposed on the other side of the cap 400. [

The first embodiment of the watering apparatus 10 according to the present invention is characterized in that the cap 700 into which the catching jaw 200 is inserted, the circular ring 800 disposed around the cap 700, And may further include a connection link 410 connected thereto.

The storage container 100 has an inner space formed therein. Accordingly, the storage container 100 can store liquid such as water inside. In addition, the storage container 100 may have various shapes. For example, the storage container 100 may have a cylindrical or polygonal duct shape.

Meanwhile, the storage container 100 may be made of a plastic material. That is, the storage container 100 may be formed of a material selected from the group consisting of polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyacrylate, polymethacrylate, polymethylacrylate, Polypropylene (PP), polyimide (PI), polymethylmethacrylate (PMMA), polystyrene, polymethyl methacrylate, polyethylacrylate, polyethylmetacrylate, (PS), polyacetal (POM), polyetheretherketone (PEEK), polyester sulfone (PES), polytetrafluoroethylene (PTFE), polyvinyl chloride (PVC), polycarbonate (PVDF), perfluoroalkyl polymer (PFA), styrene acrylonitrile polymer (SAN), and combinations thereof.

Here, the storage container 100 is preferably made of a transparent material. When the storage container 100 is transparent, the inner space can be observed with the naked eye, so that it is possible to observe whether the sample is collected or the state of the sample.

The catching jaw 200 is disposed at one side of the storage container 100 and the catcher 300 is disposed at the other side of the storage container 100.

The latching jaw 200 has a first through hole 210. A rope 400 to be described later is passed through the first through hole 210. In one embodiment, the latching jaw 200 may protrude from the storage container 100. That is, the latching jaw 200 is integrally formed with the storage container 100 and may protrude in a circular shape with respect to the center axis of the storage container 100. In addition, a thread 230 may be formed on the outer circumferential surface of the latching jaw 200. The latching jaw 200 can be inserted into a cap 700 described later. The diameter of the first through hole 210 is larger than the diameter of the rope 400 because the rope 400 to be described later flows through the first through hole 210. The catching jaw 300 is disposed so as to catch the other end of the rope 400 described later. This prevents the other end of the rope 400 from being inserted into the interior of the storage container 100.

FIG. 3 is a view showing the water intake part 300 of FIG. 1, FIG. 4 is a view showing the state where the plug 500 is opened in FIG. 3, FIG. 5a is a view showing the fixing pipe of FIG. 1, Fig. 5B is a view showing the water intake pipe of Fig.

Referring to FIGS. 1, 3 and 4, the take-in part 300 is disposed apart from the latching jaw 200. Here, the water intake part 300 includes an insert 310 having a second through hole and a water intake pipe 330 inserted into the second through hole. In the drawing, the water intake pipe 330 is inserted into the second through hole, The reference numerals for the second through holes are not shown, the same applies hereinafter).

In one embodiment, the insert 310 is inserted into the storage vessel 100. All of the insert 310 may be inserted into the storage container 100 or a portion of the insert 310 may be inserted into the storage container 100. [ That is, at least a portion of the insert 310 is inserted into the storage container 100. Accordingly, the insert 310 may have a shape corresponding to the inner space of the storage container 100.

For example, when the storage container 100 has a cylindrical shape, the insert 310 may have a circular column shape or a circular plate shape that can be inserted into the inner space of the storage container 100. In addition, when the storage container 100 has a rectangular duct shape, the insert 310 may be in the form of a square pillar or a rectangular plate that can be inserted into the storage container 100.

Meanwhile, an adhesive member (not shown) may be used for fixing the insert 310 and the storage container 100. When the insert 310 is inserted into the storage container 100 after the adhesive member is attached to the outer circumferential surface of the insert 310, the insert 310 may be fixed to the storage container 100. Further, the adhesive member may seal the space between the storage container 100 and the insert 310 to store liquid or the like. Here, the adhesive member may be a tape or an adhesive liquid.

A second through hole is formed at one side of the insert 310. The second through-hole penetrates the insert 310 up and down. A water intake pipe 330 to be described later is inserted into the second through hole.

The water intake part 300 may further include a fixing pipe 350 connected to the water intake pipe 330 and a sealing member 370 for sealing.

5A, the fixed pipe 350 includes a cylindrical fixed pipe body 350b and a fixed pipe support 350c projecting from the fixed pipe body 350b. The fixed pipe supporting portion 350c protrudes in a circular shape along the outer peripheral surface of the fixed pipe body portion 350b. A thread groove 350a is formed on the outer circumferential surface of the fixed tube body portion 350b. The thread groove 350a may be disposed adjacent to or spaced apart from the fixed tube support 350c.

4 and 5B, the water intake pipe 330 is inserted into the second through hole disposed in the insert 310. As shown in FIG. The water intake pipe 330 includes a water intake pipe body portion 330b in the form of a pipe and a water intake pipe support portion 330c disposed at one side of the water intake pipe body portion 330b. The water intake pipe 330 has a water intake hole 311 through which the sample can be introduced and a thread 330a formed on the inner peripheral surface of the water intake pipe 330.

A circular protrusion 331 is disposed at one end of the water intake pipe 330. The circular protrusion 331 protrudes from the end of the water intake pipe 330. Specifically, the circular protrusion 331 protrudes in one direction along the central axis of the water intake pipe 330. The circular protrusion 331 protrudes in a circular shape along the inner circumferential surface of the water intake pipe 330.

On the other hand, the inner diameter of the circular protrusion 331 gradually decreases from one end of the circular protrusion 331 to the other end. Specifically, the inner diameter of the circular protrusion 331 is gradually reduced along the central axis of the water intake pipe 330 in one direction (upper direction in the drawing).

The circular protrusion 331 is brought into contact with a stopper 500 to be described later, and the stopper 500 is seated on the inner circumferential surface of the circular protrusion 331. Since the inner diameter of the circular protrusion 331 gradually decreases along the central axis of the water intake pipe 330 in one direction, the stopper 500 can be brought into close contact with the circular protrusion 311. The water intake hole 311 of the water intake pipe 330 is closed by the stopper 500 and the liquid sample flowing into the interior of the storage container 100 can be prevented from flowing out through the water intake pipe 330.

FIG. 5C is a view showing a combined state of the fixing pipe of FIG. 5A and the water intake pipe of FIG. 5B.

Referring to FIGS. 1, 4, 5b and 5c, the intake pipe 330 is arranged to face the fixing pipe 350 with the insert 310 interposed therebetween. Here, either one of the water intake pipe 330 and the fixing pipe 350 may be inserted into the other one.

In one embodiment, a thread 330a may be formed on the inner circumferential surface of the water intake pipe 330. [ Specifically, the thread 330a may be spaced apart from the receiving groove 331, and may be formed to have a predetermined length along the direction of the center axis C of the water intake pipe 330.

The fixing pipe 350 is disposed in the inner space of the storage container 100. A thread groove 350a corresponding to the thread 330a may be formed on the outer circumferential surface of the fixing pipe 350. [ Therefore, the fixing pipe 350 can be inserted into and screwed into the water intake pipe 330. Here, the fixing pipe 350 may be partially or fully inserted into the water intake pipe 330. Even if the fixing pipe 350 is inserted into the water intake pipe 330, the liquid sample can be introduced into the inner space of the storage container 100 through the hole formed in the fixing pipe 350.

In another embodiment, the fixing pipe 350 and the water intake pipe 330 may not be provided with the screw thread 330a and the screw groove 350a. In this case, the fixing pipe 350 is inserted into the water intake pipe 330 but can be forcedly inserted.

The sealing member 370 may be disposed between the insert 310 and the water intake pipe 330. Specifically, the sealing member 370 may be disposed between the intake pipe support portion 330c and the insert 310. [ The sealing member 370 has an annular shape, and the water intake pipe 330 can be inserted into the inside thereof. The sealing member 370 is compressed by the engagement of the water intake pipe 330 and the fixing pipe 350 so as to seal the space between the insertion pipe 310 and the water intake pipe 330.

1 and 4, the rope 400 has a certain length and is disposed in the inner space of the storage container 100. [ Particularly, one end of the rope 400 passes through the water intake hole 311, and the other end of the rope 400 passes through the through hole 210.

A cap 500 is connected to one end of the rope 400. At this time, a connection loop 410c may be disposed between the cap 500 and the rope 400. [ That is, the cap 500 is connected to the rope 400 through the connection ring 410c, thereby having fluidity. This facilitates that the stopper 500 is seated on the circular protrusion 331. The stopper 500 is preferably made of an elastic material so as to be in close contact with the circular protrusion 331.

The plug 500 serves to open or close the water intake hole 311. In particular, the cap 500 is in contact with the inside of the circular protrusion 331 formed in the water intake pipe 330. The inner diameter of the circular protrusion 331 gradually decreases in one direction along the central axis of the water intake pipe 330 so that the stopper 500 can be brought into close contact with the circular protrusion 331.

The weight 600 is connected to the cap 500. The weight 600 may be disposed adjacent to the perimeter of the cap 500. The weight 600 may be directly connected to the plug 500 or may be indirectly connected by other components.

The weights 600 sink in the sample liquid. Therefore, the cap 500 connected to the weight 600 is separated from the water intake part 300. For this purpose, the weight 600 should have a specific gravity greater than one. When the specific weight of the weight 600 is greater than 1, the weight 600 sinks down in the water.

More specifically, the weight 600 may have a density greater than the density of the sample liquid. For example, when the liquid to be a sample is oil having a density lower than that of water, the weight 600 may have a density greater than that of oil.

The other end of the rope 400 may have an "O " -shaped ring 413 (hereinafter referred to as an oval ring). The oblong rings 413 can be formed by knotting the ropes 400. Meanwhile, the other end of the rope 400 is connected to the throwing rods 430. The throw string 430 is used to throw the storage vessel 100 a long distance or pull the storage vessel 100 out.

At least one linking ring 410a, 410b may be disposed between the other end of the rope 400 and the throwing rods 430. For example, one linking ring 410a may be connected to the oblong ring 413 disposed at the other end of the rope 400. In addition, another connecting link 410b may be connected to one end of the throwing strand 430. [

Referring to FIGS. 1 and 2, the cap 700 is disposed around the latching jaw 200 and has a hole communicating with the through hole 210. Thus, the other end of the rope 400 passes through the catching jaw 200 and the cap 700. In addition, the latching jaw 200 protruding from the storage container 100 can be inserted into the cap 700. At this time, the cap 700 has a screw groove (not shown) corresponding to the screw thread 230 formed on the outer peripheral surface of the latching jaw 200. As a result, the cap 700 can be screwed with the engaging jaw 200.

The circular ring 800 is disposed adjacent to the latching jaw 200 with the cap 700 interposed therebetween. The rope 400 passing through the cap 700 passes through the circular ring 800. Here, the diameter (outermost diameter) of the circular ring 800 is larger than the diameter of the hole formed in the cap 700. Therefore, it is possible to prevent the knot 411 formed at the other end of the rope 400 from being inserted into the hole formed in the cap 700. That is, the circular ring 800 restricts the flow of the rope 400 knot 411 so that the other end of the rope 400 is not inserted into the inner space of the storage container 100.

The watering apparatus 20 according to the second embodiment of the present invention may further include the buoy 900 in addition to the components of the first embodiment. The second embodiment will be described with reference to Fig.

6 is a view showing a watering apparatus 20 according to a second embodiment of the present invention.

The buoy 900 may be connected to one side of the water taking apparatus 20. That is, the buoy 900 may be connected to the storage container 100, the rope 400, and the coupling ring 410, or the like. The buoy 900 may be connected to the water taking apparatus 10 by a separate connecting line.

The buoy 900 is a floating structure on the surface of the water. For example, the storage container 100, which is thrown into the water surface, gradually sinks below the water as water flows into the internal space. At this time, the buoy 900 flies on the surface of the water to confirm the position of the storage container 100. The buoy 900 also prevents the storage vessel 100 from sinking to the underwater floor.

The configuration of the water collection apparatuses 10 and 20 according to the first and second embodiments of the present invention has been described so far and the operation of the water collection apparatuses 10 and 20 according to the embodiment of the present invention Explain. 7 and 8 are views for explaining the operation of the water collection apparatuses 10 and 20 according to the present invention.

Referring to FIGS. 6, 7 and 8, the storage vessel 100 is thrown to a position where the desiccant sample is to be collected. When the storage container 100 is thrown to the surface, the weight 600 sinks below the surface of the water. At this time, the cap 500 connected to the weight 600 also sinks below the water surface. Thereby, the plug 500 is separated from the water intake pipe 330 and the water intake hole 311 is opened.

The knot 411 or the circular ring 800 of the rope 400 is caught by the catching jaw 200 or the cap 700 when the weight 600 sinks into the water of a predetermined depth. Accordingly, the flow of the rope 400 is restricted, whereby the water intake part 300 is locked at a certain position below the water surface. At this time, the liquid sample 100a flows into the internal space of the storage container 100 through the water intake hole 311. The storage container 100 gradually sinks below the water surface while the sample 100a is introduced. The buoy 900 provides buoyancy to the storage vessel 100 so that the vessel of storage vessel 100 does not sink deep into the water. In addition, the position of the storage container 100 can be confirmed by the buoy 900.

When pulling the throw string 430, the rope 400 connected to the throw string 430 is pulled. When the rope 400 is pulled, the cap 500 connected to one end of the rope 400 is brought into contact with the water intake pipe 330. At this time, the cap 400 is seated on the circular protrusion 331 of the water intake pipe 330. The inner diameter of the circular protrusion 331 gradually decreases along the central axis of the water intake pipe 330 in one direction. Therefore, the cap 400 is brought into close contact with the water intake pipe 330 to prevent the sample 100a flowing into the interior of the storage container 100 from flowing out.

The catch hole 311 is kept closed by the stopper 400 while the throw string 430 is continuously pulled. When the tension of the throw string 430 is removed, the plug 400 is separated from the water intake pipe 330 and the water intake hole 311 is opened. At this time, the sample 100a in the storage container 100 may be discharged.

The water collection apparatus (10, 20) according to the present invention can collect a sample at a position distant from an operator to collect water. The catch hole (311) is closed by the stopper (400) while pulling the throw string (430). Therefore, it is possible to prevent a sample at another position from being sampled other than the sample at a specific position.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood that the invention may be practiced. It is therefore to be understood that the embodiments described above are illustrative in all aspects and not restrictive.
