Description

Contaminant removal device used at low water level {CONTAMINANT REMOVING APPARATUS USED AT LOW WATER LEVELS}

The present invention relates to a contaminant removal device used at low water levels, and more specifically, to a contaminant removal device used at a low water level, such as an artificial lake, by installing it on a boat, etc., and spraying compressed air while sucking in contaminants. This makes it possible to easily and quickly remove contaminants stuck to the surface while reducing maintenance costs. At this time, by inhaling the contaminants and spraying compressed air, the contaminants can be removed effectively while minimizing their spread to the sides.

Generally, in places where there is water above a certain level, contaminants settle to the bottom over time or the bottom becomes contaminated due to abnormal growth of algae, which are aquatic organisms. Such contaminated floors can be purified through natural purification methods, but natural purification does not occur properly when the current is not strong or water is stagnant for a long time, such as in an artificial lake or dam. Accordingly, as shown in (Patent Document 1) to (Patent Document 3) below, contaminants are removed so that purification can be achieved using floor cleaning technology.

However, these existing technologies for removing contaminants have the following problems when removing contaminants in places with low water levels, such as artificial lakes.

(1) Typically, when creating an artificial lake, not only is the bottom flat, but the water depth is often low. Accordingly, existing pollutant removal devices can be easily used in deep water, but cannot be used in low water depths such as artificial lakes.

(2) Therefore, when managing an artificial lake, contaminants such as oil or green algae that float on the surface of the water must be removed by manpower using boats, etc. This significantly reduces the contaminant removal effect.

(3) In particular, artificial lakes are often equipped with boats, amusement facilities, and docks, and if the oil from these is not removed immediately, there is a risk that it may mix with other contaminants and settle out. This precipitated oil not only disrupts biodiversity by forming an oil slick on the bottom of the artificial lake, but also becomes a factor in polluting the bottom of the artificial lake.

(4) In addition, contaminants that settle in this way may seep into places such as rocks or crevices at the bottom of an artificial lake, and the contaminants that seep in like this cannot be removed with a scoop, so the effectiveness of removing contaminants is significantly reduced.

The present invention takes this into consideration, and consists of a base that absorbs contaminants while floating at a certain height from the floor and spraying compressed air to easily float contaminants adhering to rocks, etc., so that contaminants can be absorbed quickly. The purpose is to provide a contaminant removal device used at low water levels that not only allows easy and convenient removal of contaminants even in artificial lakes with low water levels, but also allows contaminants to be removed by easily changing the removal location using a boat, etc. there is.

In particular, the present invention uses a submersible pump to first absorb contaminants and then sprays compressed air to make the contaminants float, so that not only can contaminants that stick to rough rocks or become trapped in gaps be easily and conveniently removed. Another purpose is to provide a contaminant removal device used at low water levels that can further increase the contaminant removal effect by preventing contaminants from escaping from below the base to the side.

In addition, the present invention sprays compressed air through several nozzles through a distribution pipe on a grid-shaped base, allowing contaminants adhering to a predetermined space to float, thereby increasing the contaminant removal effect, while also increasing the contaminant removal effect within a certain size contaminant removal range. Another purpose is to provide a contaminant removal device used at low water levels that can quickly and cleanly remove contaminants.

A contaminant removal device used at a low water level according to the present invention to achieve this purpose includes a contaminant removal device installed on a boat used in an artificial lake with a low water level or a structure floating on the water to remove contaminants; A grid-shaped base (100) made of an empty frame on the inside and formed on the outside with several suction holes (110) through which contaminants can be sucked in; a submersible pump 200 mounted on the base 100 to allow contaminants to flow into the base 100 through the suction hole 110 and then discharge the introduced contaminants to the outside; and an air injection device 300 mounted on the base 100 or the submersible pump 200 and spraying compressed air supplied from an externally installed compressor 310 into the area where contaminants are sucked into the suction hole 110; It is characterized by including.

In particular, the air injection device 300 is disposed in a wound form along the edge of the submersible pump 200 installed on the base 100, and has a distribution pipe 320 on the outside of which at least two nozzles 321 are installed. ); And a supply pipe 330 connected to the distributor 320 to supply compressed air from the compressor 310.

In addition, the contaminant removal device operates the submersible pump 200 to suck contaminants into the suction hole 110, and sprays compressed air from the air injection device 300 to make the contaminants float. This is characterized by ensuring good suction.

The contaminant removal device used at low water levels according to the present invention has the following effects.

(1) Since contaminants are sucked in through several suction holes mounted on the base and compressed air is sprayed to make the contaminants float, contaminants can be removed cleanly from every corner even in places with low water levels, such as artificial lakes.

(2) In particular, the contaminant removal device according to the present invention can be used by being mounted on a boat used in an artificial lake, so that contaminants can be removed in an automatic manner, thereby increasing the contaminant removal effect and performing contaminant removal work quickly and cleanly. can do.

(3) The structure is simple, so it can be manufactured easily and inexpensively and used conveniently. In addition, by installing several contaminant removal devices according to the present invention on boats, etc., the contaminant removal effect can be increased over a large area at once.

(4) Even if contaminants generated from structures or boats installed in the artificial lake settle to the bottom of the artificial lake, the contaminants can be easily removed, making it possible to manage water quality throughout the artificial lake.

(5) Compressed air is sprayed to the bottom of the artificial lake to make the contaminants float and are sucked into the suction hole to remove the contaminants. Even if contaminants are stuck on rough stone surfaces or crevices, they can easily float through the compressed air to achieve the contaminant removal effect. It can be raised even further.

(6) On the other hand, the present invention allows contaminants to be sucked in first, and then sprays compressed air to control the contaminants to float, thereby preventing contaminants from spreading sideways in the area where contaminants are removed, thereby further increasing the contaminant removal effect. .

It must be interpreted with meaning and concept consistent with the technical idea of the present invention according to the principle that it can be done.

Therefore, the embodiments described in this specification and the configurations shown in the drawings are only one of the most preferred embodiments of the present invention and do not represent the entire technical idea of the present invention, so various equivalents can be substituted for them at the time of filing the present application. It should be understood that there may be variations.

[Configuration of pollutant removal device]

The contaminant removal device used at low water level according to the present invention includes a base 100, a submersible pump 200, and an air injection device 300, as shown in [FIGS. 1] to [FIG. 6].

In particular, the base 100 is equipped with several suction holes 110 so that contaminants are sucked in and discharged to the outside as the submersible pump 200 operates, and the air injection device ( The compressed air sprayed from 300) causes contaminants on the floor to float, thereby increasing the contaminant removal effect and making it possible to easily and conveniently remove contaminants that stick to rough rocks or become stuck in gaps.

In addition, the air injection device 300 is configured to spray compressed air by mounting at least two nozzles 321 on the distribution pipe 320, so that contaminants in the lower part of the base 100 float and the suction hole ( 110), making it possible to remove contaminants easily and quickly.

Meanwhile, the air injection device 300 is configured to spray compressed air on the floor while contaminants are sucked into the suction hole 110 through the submersible pump 200, so that contaminants floating on the floor are transferred to the base 100. This allows for clean suction through the suction hole 110 without spreading out from below to the side.

Hereinafter, this configuration will be described in more detail with reference to the attached drawings. Here, 'bottom' refers to an underwater bottom, like an artificial lake, where the water level is low but at a water level where boats, etc. can pass.

go. Base

As shown in [FIG. 1] and [FIG. 2], the base 100 is used by being mounted on a boat (B) used in an artificial lake or a floating structure to remove contaminants with the contaminant removal device according to the present invention. . At this time, the base 100 is used by being mounted on a boat (B), etc. using a hose, tube, or pipe to remove contaminants sucked in by driving the submersible pump 200, which will be described later. At this time, the base 100 may be mounted so that its height can be adjusted by submerging it in an artificial hose, etc. using a separately manufactured rope.

Meanwhile, in a preferred embodiment of the present invention, the base 100 is preferably manufactured and used using a frame with an empty interior, as shown in [FIG. 4]. This is because several suction holes 110 are formed outside the base 100, and contaminants are collected in the base 100 through the suction holes 110 by driving the submersible pump 200, which will be described later, and then discharged out of the water. This is so that you can do it.

It is preferable that the base 100 is manufactured in a lattice form, as shown in [FIGS. 2] to [FIG. 4]. This forms several suction holes 110 on one side of the grid-shaped base 100 to enable suction of contaminants over a wide range, and on the other side, a submersible pump 200 and an air injection device (described later) are installed on the other side. This is to ensure that 300) can be mounted stably.

me. submersible pump

The submersible pump 200 is mounted on one side of the base 100 described above, preferably on the side where the suction hole 110 is not formed, as shown in FIGS. 1 to 4. At this time, the submersible pump 200 causes contaminants to be sucked into the base 100 through the suction hole 110 formed in the base 100 through a suction action within the hollow base 100, thereby bringing the suctioned contaminants to the surface. Let it come out. Accordingly, it is desirable to equip the boat (B), etc. with a container capable of storing such discharged contaminants.

Here, the submersible pump 200 is manufactured using conventional technology, and to this submersible pump 200, as shown in [FIGS. 1] and [FIG. 2], a discharge pipe 210 is connected to the suction hole ( 110) allows the inhaled contaminants to be discharged out of the water surface. At this time, the discharge pipe 210 can use a pipe or hose, and it is desirable to use the discharge pipe 210 not only to discharge contaminants to the outside, but also to adjust the height of the base 100.

That is, the base 100 is brought into contact with the floor using the discharge pipe 210, as shown in [FIG. 1], [FIG. 5], and [FIG. 7], and then the discharge pipe 210 is lifted upward to the base. (100) is lifted from the floor to a certain height to inhale contaminants. At this time, the discharge pipe 210 is also used as a height adjustment means when the base 100 touches the floor and is lifted from the floor to a certain height.

This submersible pump 200 is preferably connected to a container loaded on a boat B through the discharge pipe 210, as shown in [FIG. 1], so that the sucked contaminants can be stored.

all. air blower

As shown in [FIGS. 1] to [FIG. 4], the air injection device 300 is mounted on the base 100 or the submersible pump 200 and sprays compressed air supplied from the outside to the bottom to spray on rough rocks. It allows contaminants stuck or stuck in gaps to float, thereby increasing the contaminant removal effect.

This air injection device 300 includes a distribution pipe 320 and a supply pipe 330, as shown in [FIG. 2] to [FIG. 4].

One. distribution pipe

As shown in [FIG. 2] to [FIG. 4], the distribution pipe 320 is equipped with several nozzles (to allow the compressed air to be sprayed widely over a certain range when spraying air from the base 100 described above toward the floor). 321) is a pipe for mounting.

Accordingly, the distribution pipe 320 is installed on the base 100 to be located at the edge of the submersible pump 200, as shown in [FIG. 3] and [FIG. 4]. This causes the compressed air sprayed from at least two nozzles 321 installed in the distribution pipe 320 to be sprayed evenly on the bottom portion corresponding to the lower part of the base 100, thereby removing contaminants that stick to rough rocks or become trapped in gaps. This is to increase the effect of contaminant intake by making it float along with the contaminants on the bottom.

2. supply pipe

The supply pipe 330 is a pipe for supplying compressed air to the distribution pipe 320 described above, as shown in [FIGS. 2] to [FIG. 4]. Accordingly, the supply pipe 330 is installed to receive compressed air from the outside through a compressor 310 installed on a boat (B) and distribute it to the distribution pipe 320 described above.

The air injection device 300 configured in this way is operated by driving the submersible pump 200 described above as shown in [FIG. 5], allowing contaminants to be sucked through the suction hole 110, and the compressor as shown in [FIG. 6]. Compressed air supplied from 310 is sprayed onto the floor below the base 100 to float contaminants, thereby increasing the contaminant removal effect.

As described above, the present invention sprays compressed air during suction to make contaminants float, so that contaminants can be easily and conveniently removed even in artificial lakes with low water levels, as well as contaminants that stick to rough rocks or become lodged in gaps. The removal effect can be further enhanced by easily floating it with compressed air.
