Especially, the polluted water can be discharged to the water without leaking into water other than the hopper And more particularly to a system and system for cleaning a lake floor.

The bottom of the artificial lake usually produces aquatic plants or sediments naturally, and when the lake is used as a yacht park, artificial sediments are also added to the bottom of the lake (see FIG. 1). Unless these dirt are cleaned periodically, artificial lakes can not be used for their intended purpose. Therefore, researches for purifying artificial lakes by various methods have been conventionally conducted, and natural purification methods, surface coating methods, and polluted sediment collection methods are being developed as main methods.

In detail, the natural purification method is a method that can be adopted when the influence of the ecosystem is not serious and the ability to self-purify in a desired time is provided.

The surface coating method is a method of forcibly coating a contaminated sediment layer using high quality gravel, gravel, and sand. However, the surface coating method is a temporary method for suppressing the deepening of contamination, and there is a problem that corruption accompanied by odor is generated particularly when sediment accumulates under the cloth.

In summary, the underwater floor cleaning apparatus according to the present invention can operate as shown in FIG. Reference numeral 200 denotes a longitudinally extending injection port (injection pipe) for spraying high-pressure water. High-pressure water injected from the injection port 200a penetrates to the bottom of the lake below the gravel to remove dirt on the bottom of the lake.

The term "lake" used in the present invention is intended to be used for purposes such as parks, amusement parks and the like in the form of water tanks and waterways in which water is confined within a certain range regardless of fresh water or seawater. And narrowly means a yacht park with a depth of 1.5 meters. The term "dirt " as used in the present invention encompasses a cement structure in parks, aquatic plants (including spores) attached to gravel, and aquatic plants, sediments and sediments attached to cement structures or gravel. Gravels at yacht parks and the like are usually laid on artificial cement structures for the purpose of natural ecosystem formation. The term "contaminated water" used in the present invention means an object to be discharged in a state in which water and dirt are mixed as the dirt is removed from the bottom.

4 and 5 are sectional views for explaining a ladle bottom cleaning apparatus according to a first embodiment of the present invention.

4 and 5, high-pressure water is injected through the injection mechanism 312 located at the injection port 310 in the hopper 300 moving in the submerged state to remove the dirt 102 at the bottom of the lake The polluted water 101 containing the dirt 102 is discharged through the discharge port 320 to the outside of the lake. At this time, in order to suppress the phenomenon that the contaminated water 101 is leaked to the outer wall of the hopper 300, water (contaminated water (hereinafter referred to as " water ") discharged to the outside of the hopper 300 101) is set to be larger.

Here, the hopper 300 has an airtight structure capable of confining contaminated water, and the injection port 310 and the discharge port 320 are formed on the outer wall, and the lower surface has an open shape. In other words, the outer wall of the hopper 300 includes a side wall portion and an upper portion, and a jetting port 310 and an outlet port 320 are formed in a part of the side wall portion or the upper portion. It touches. At this time, a rubber plate is attached to the interface between the side wall and the bottom of the lake, so that the polluted water can be minimally discharged to the river. The hopper 300 interlocks with a ship to be described later and performs cleaning while moving in water.

The injection pump 311 serving as the first pump serves to inject water from the outside of the hopper 300 and inject water into the hopper 300. The injection pump 311 injects water from the injection port 310a of the hopper 300 310, respectively. The discharge pump 321 serving as the second pump serves to discharge the contaminated water 101 to the outside of the hopper 300 and is disposed between the discharge port 320 of the hopper 300 and the discharge pipe 320a do. The injection pump 311 and the discharge pump 321 are controlled by power using AC or DC power, and the quantity of each pump is controlled according to the power supply level.

Each component and operation will be described as follows.

The hopper 300 includes a jetting port 310 for jetting water to clean the bottom of the water while the jetting port 310 is connected to the jetting mechanism 312 and supplies the contaminated water 101, Is a member of the concept of forming a housing of the overall cleaning device to shield the space. At this time, the lower surface of the hopper 300 is in contact with the lake bottom surface 103, and the jetting mechanism 312 injects water to the lake bottom surface 103.

That is, in order to confine the contaminated water 101 to be cleaned by the spraying of water into the hopper 300, the amount of the contaminated water 101 discharged to the discharge port 320 by the discharge pump 321 is supplied by the injection pump 311 The amount of water sprayed into the hopper 300 should be greater than the amount of water sprayed into the hopper 300. At this time, the deficient water due to the difference in quantity between the two is sucked through the space 310a between the bottom and the bottom of the hopper 300 and discharged to the discharge port 320, The leakage and the discharge of the contaminated water to the outside of the apparatus can be prevented.

At this time, the water to be sprayed is made through one or more nozzles. That is, the injection mechanism 312 includes one or more nozzles 313. Accordingly, when the direction of the sprayed water is sprayed in a diagonal line from the side of the hopper 300 toward the center, it is possible to minimize the polluted water 101 leaking to the outside of the hopper 300. Fig. 5 shows the above operation.

5, the water supplied to the injection pump 311 is supplied to the injection mechanism 312 through the injection port 310 and the water supplied to the injection mechanism 312 is supplied to one or more nozzles 313 And injects high-pressure water through the hopper 300 toward the bottom of the lake. At this time, high-pressure water is injected in an inclined direction 314 from the vertical plane so as to inject water in the three-dimensional direction inside the hopper 300. It is preferable that the inclination degree is set to any range of 70 degrees or less from the vertical plane into the interior angle of the hopper 300.

In short, according to the first embodiment of the present invention, the hopper 300 is capable of spraying water toward the bottom of the lake, and the hopper 300 is opened so that the lower surface thereof is opened and the side wall portion and the upper surface thereof hold the polluted water 101 The direction of the water injected through the injection port 310 is formed in a sectorial direction from the outer wall of the hopper 300 to the center thereof, (314), and the polluted water (101) is discharged to the discharge port (320).

6 is a view showing a structure of the hopper 300 according to the present invention. Referring to FIG. 6, the hopper 300 is a closed structure surrounded by the upper portion 301 and the side wall portion 302. The injection port 310 is connected to the nozzle 313 of the injection mechanism 312 formed inside the hopper 300. The water supplied to the jetting port 310 is structured such that the water in the lake is pumped by the jetting pump 311 and supplied. However, a pipe may be formed to supply clean water from the outside.

5 and 6, the polluted water 101 discharged using the discharge pump 321 is discharged to the outside of the hopper 300 through the discharge port 320. The discharge pipe 320a is connected to the bottom of the settling tank 700 to filter the polluted water 101. The discharge pump 321 may not be located in the water.

The filter 322 is positioned inside the hopper 300 to prevent the gravel at the bottom of the lake from escaping to the discharge port 320. The filter 322 is desirably selected to have an appropriate thickness for passing the polluted water 101 and filtering the gravel. Particularly, as described below, when the air (gas) is injected into the hopper 300, the gravel floats between the filter 322 and the space on the bottom of the lake, so that the cleaning effect is further improved.

Meanwhile, the hopper 300 may further include at least one propeller-type cutting blade for removing a few seconds. Fig. 7 shows an example of a propeller-type cutting blade. Referring to Figure 7, each of the at least one propeller-type cutting edges operates with the cutting blade rotating within a blade support that supports the cutting blade on the basis of the rotation bar. At this time, the cutting blade rotates based on the electric power supplied from the hydraulic motor. As a result, aquatic plants (native plants) such as parasites can be removed.

8 shows a photograph of the hopper 300, the injection pump 311 and the discharge pump 321 according to an embodiment of the present invention. 9 is a view showing a state in which water is injected from the injection mechanism 312, that is, one or more nozzles 313, according to an embodiment of the present invention. Through this, high pressure water is injected from one or more nozzles 313. The lower view of Fig. 9 shows the difference between the underwater floor 313a before cleaning and the underwater floor 313b after cleaning. It can be confirmed that the bottom of the lake under the gravel is thoroughly cleaned through the lake floor cleaning apparatus according to the present invention.

Further, the amount of water to be sprayed and the amount of water to be discharged (the amount of the contaminated water 101) can be set by controlling the power of the independent electric motor unit or by controlling the opening amount of the independent valve unit. Furthermore, the amount of water to be sprayed and the amount of water to be discharged (the contaminated water 101) can be automatically controlled so as to be maintained at a constant difference in association with the water quantity sensor and the control means.

Here, "control of the independent electric motor part" means control using a power mechanism such as the injection pump 311 and the discharge pump 321. [ That is, if the power of the injection pump 311 is controlled to be smaller than the power of the discharge pump 321, the water flow is sucked toward the hopper 300 in the space between the lower surface of the hopper 300 and the bottom surface of the lake A phenomenon in which the polluted water 101 leaks and is released into a space in the water can be suppressed. In other words, it is possible to control the operation of the injection pump 311 and the operation of the discharge pump 321 so that the amount of the contaminated water 101 is larger than the amount of water to be sprayed.

At this time, the operation of the injection pump 311 and the operation control of the discharge pump 321 may be performed automatically or manually. If performed automatically, the lagoon floor cleaning apparatus may further include a quantity sensor and a pump power control unit. The quantity sensor is a sensor located in the piping path of each of the injection pump 311 and the discharge pump 321 and sensing a water pressure or a water flow. The pump power control unit controls the power of the injection pump 311 and the discharge pump 321 based on the quantity detected by the quantity sensor. That is, when the quantity of the discharge port 320 is smaller than the quantity of the injection port 310 by sensing the quantity sensor, the operation of automatically raising the power of the discharge pump 321 and lowering the power of the injection pump 311 is performed automatically . However, this control operation can be adjusted by the workforce while observing the leakage phenomenon without using the quantity sensor.

In addition, "controlling the amount of opening of the independent valve portion" means controlling the flow rate of the valve by opening and closing the valve. That is, by controlling the opening amount of the injection port 310 and the opening amount of the discharge port 320, it is possible to set the amount of polluted water to be larger than the amount of water to be sprayed. At this time, the control of the opening amount can be performed manually or automatically.

On the other hand, since the water to be sprayed should be maintained as large as a certain difference compared to the water pressure at the bottom of the lake, it is preferable to maintain the water in the range of 0.1 to 2 atmospheres depending on the degree of dirt on the bottom surface of the lake. That is, since the atmospheric pressure of the water surface is 1 atm, for example, to clean the floor of a 1.5 m lake, the water pressure should be set at a suitable pressure difference between 1.6 atmospheres and 3.15 atmospheres, can do. At this time, if the depth of the bottom of the lake is detected by the water pressure sensor and is controlled by interlocking with the injection pump 311, the strength of the water pressure can be automatically adjusted according to the depth of the lake to be cleaned.

4 to 7 are applicable to the second embodiment of the present invention. That is, in the apparatus for cleaning a lake floor according to the second embodiment of the present invention, high-pressure water is injected in a hopper 300 moving in a submerged state to remove dirt on the bottom of a lake, The amount of water injected into the hopper 300 is lower than the amount of water injected to the inside of the hopper 300 so as to suppress the phenomenon that the contaminated water 101 leaks to the outer wall of the hopper 300, The amount of water discharged to the outside can be set to be large and the bottom surface of the lake can be cleaned by injecting high pressure air (gas) together with high pressure water in the hopper 300.

That is, in the configuration of "cleaning the bottom surface of the lake by spraying the air (gas) ", a certain space in the hopper 300 ejects water and the space in the other space ejects air (gas). For example, water is sprayed to clean the floor, then air (gas) is sprayed. In this way, disinfection of the bottom of the lake can be carried out, and the gravel can float in the water, and further cleaning can be carried out effectively.

At this time, the air (gas) is spatially separated injection which makes the position of spraying the water and the position of spraying the air (gas) different, or spraying is performed by temporally separated spray which alternates the spray of water and the spray of air . That is, in the case of spatially separated injection, some of the one or more nozzles 313 spray water and the rest of the one or more nozzles 313 spray air. Also, in the case of temporally separated injection, all of the one or more nozzles 313 spray water during the first time, and all of the one or more nozzles 313 spray the air during the second time after the first time.

In this case, when the air is sprayed, it is preferable to operate the air pump at a difference of 0.5 atm or more from the water pressure (atmospheric pressure) of the bottom surface of the lake. In this case, have. At this time, the air pump may correspond to the injection pump 311, that is, the first pump. In this case, it is preferable that the air pump is installed on the water surface and the air pipe and the air nozzle to be supplied from the water surface are provided in the hopper 300.

In addition, since the detailed structure of the apparatus for cleaning the bottom of the lake according to the first embodiment of the present invention can be applied, the detailed description will be omitted.

4 to 7 are applicable to the third embodiment of the present invention. In other words, the apparatus for cleaning the bottom of the lake according to the third embodiment of the present invention removes the dirt 102 from the bottom of the lake, discharges the polluted water 101 containing the dirt 102 out of the lake, Pressure air in the hopper 300 moving in the hopper 300 to move the gravel to the space between the filter 322 located in the hopper 300 and the bottom surface 103 of the lake, At the same time, fresh air is injected into the bottom of the lake to purify the gas from the dirt 102.

That is, the apparatus for cleaning the bottom of the lake according to the third embodiment of the present invention is an air pump provided with the above-described injection pump 311 on the water surface, and the injection port 310, the injection mechanism 312 and the nozzle 313, , Air pipes and air nozzles. However, in the third embodiment of the present invention, the gravel is floated in the water from the lake bottom surface 103 by air, and the gravel or the mesh of the filter 322 between the filter 322 and the lake bottom surface 103 And the gravel are rubbed to clean the dirt. At the same time, the fresh air acts to purify the gas generated in the dirt 102 at the bottom of the lake. Therefore, in the first embodiment and the second embodiment, There is a difference.

And, in the third embodiment of the present invention, the air to be sprayed may be a gas which plays a role of disinfecting through oxygen to disinfecting material. That is, the third embodiment of the present invention is characterized in that the bottom of the lake is cleaned by spraying air in addition to the spraying of water described in the first and second embodiments. In this case, the gravel is floated in the water, The filter 322 is moved up and down in a space between the filter 322 installed at the site and the bottom 103 of the lake, or the gravel collides with each other to positively remove the dirt 102 to perform cleaning. Accordingly, a physical (mechanical) brush structure is not required and the cleaning effect can be improved while obtaining the effect corresponding to the conventional brush.

In order to inject air, it is preferable to operate the air pump so as to inject air toward the lake bottom surface 103 at a constant air pressure difference from the water pressure (atmospheric pressure) of the lake bottom surface 103. On the other hand, The same principle as described in < / RTI > However, in the third embodiment, since the water pressure in the hopper 300 is lowered by discharging the contaminated water 101 through the discharge pump 321 in the state where water is not sprayed, the contaminated water 101 is discharged outside the hopper 300, And the vortex of the vortex in the hopper 300 largely acts even with a small air pump pressure so that the friction between the gravel and the gravel collide against the filter 322, .

In addition, programming can be done automatically at a defined time or period in a given lake.

That is, the vessel 400 can be operated to automatically clean the pre-compartmented area on the map in the smartphone or the remote control room by moving the four independent pulleys 411 individually within the set range of the lake. At this time, the video camera monitors the operation state remotely, and the captured image is transmitted to the remote control room or smart phone through the communication network. Also, the GPS can autonomously travel the vessel 400 to position itself on the vessel.

In addition, the ship 400 can be manually operated by a user to manually control the ship 400. This manual operation is the most preferable operating method of the present invention.
