Description

Rainwater gutter with basket for sludge recovery

The present invention relates to a rainwater catcher having a sludge recovery basket, which is installed on the border of a road or sidewalk (in a downtown residential area, park, highway or local road, and at construction sites nationwide) to collect rainwater, and which comprises a cassette pull-out basket inserted into a rainwater catcher, and which, when sludge is removed and recovered, can be lifted from the rainwater catcher and simply separated, so that when settled sludge accumulates, it can be collected and removed all at once (at one time or at a time).

This invention can fundamentally resolve the previous labor of manually scooping out sludge one by one using a shovel or a spade, guarantees rapid workability according to sludge treatment, and significantly reduces the work man-hours (the unnecessary accompanying auxiliary materials), and is formed so as to prevent safety accidents while greatly reducing labor costs by enabling smooth work, and in particular, is characterized by significantly improving flood accidents caused by road overflow or rainwater backflow.

In addition, the present invention is characterized by being easily applicable to existing rainwater collectors, allowing easy compatible application without replacement (exchange) of the existing structure, and being easy to mount and detach (install and separate for recovery), thus facilitating excellent handling and management.

In addition, the present invention is characterized in that it is possible to separately remove non-point source pollutants such as leaves, cigarette butts, and trash, such as floating matters and impurities, in addition to sludge sediment by further installing a mesh basket inside the basket, thereby improving filtration efficiency during the process of being filtered through a water treatment facility (after passing through a sewage treatment plant or a sewage treatment plant and then finally being discharged into a river).

A street inlet is a concrete structure installed at regular intervals in the side drain of a road and connected to the sewer main through an outflow pipe.

These rainwater catchers collect rainwater flowing into road ditches, residential areas, etc. and discharge it into the sewer main.

Once it starts to rain, the roads are flooded with debris such as trash, branches, and floating objects, as well as non-point source pollutants including heavy metals, pathogenic microorganisms, organic compounds, radioactive substances, and toxic substances, along with the initial rainwater flowing toward the drains. In addition, soil and dirt run off, causing sludge to accumulate in the rainwater catch basins.

In other words, when rainfall occurs, soil and various floating materials pass through the steel grating and settle (sediment) inside the rainwater catcher.

Therefore, conventional rainwater catchers often have drains clogged by sediment, and when this happens, the drain becomes clogged, loses its function, and backflow occurs, so periodic or infrequent maintenance is inevitably required.

At this time, the previous maintenance work involved removing the steel grating from the rainwater gutters and having multiple workers manually scoop out the sediment inside the rainwater gutters with shovels or scoops. This sludge removal work required a lot of labor, so not only did it cost a lot of labor costs, it also took a considerable amount of time (causing traffic congestion), and in particular, it caused secondary problems such as exposure to the risk of work-related safety accidents (personnel accidents, traffic accidents, etc.).

In addition, the conventional rainwater catch basin is structured in a way that it is impossible to visually check how much sediment has accumulated until the grating is opened and closed, so maintenance is still required only when rainwater flows back, which continues to be a problem.

In addition, there is an ongoing problem that rainwater discharged does not contribute to improving the water quality at all because floating matter or impurities and sediment sludge are mixed with rainwater and discharged into the watershed as is.

1. Republic of Korea Patent Publication No. 10-2017-0079458 (published on July 10, 2017)

In order to solve the above-described problem, the present invention provides a method in which a cassette-type basket is inserted into a rainwater collecting tank, and the basket can be lifted from the rainwater collecting tank and simply separated when sludge is removed, so that when settled sludge accumulates, it can be collected and removed at once (at one time or at a time).

The purpose of this invention is to provide something that can fundamentally eliminate the laborious work of previously having to manually dig up soil one by one using a shovel or a spade.

Accordingly, the purpose of the present invention is to provide a method that ensures rapid workability according to sludge treatment and significantly reduces work man-hours (no need for additional auxiliary materials).

In addition, the purpose of the present invention is to provide a structure that enables smooth operation, thereby preventing safety accidents while at the same time greatly reducing labor costs, and in particular, to significantly improve flood accidents caused by road overflow or rainwater backflow.

Accordingly, the purpose of the present invention is to provide a method that can be simply applied to an existing rainwater catcher, and to enable easy compatible application without replacing (replacing) the existing structure, as well as easy mounting and dismounting (installation and separation for recovery), thereby providing excellent handling and management.

In addition, the purpose of the present invention is to provide a method in which a mesh basket is additionally installed inside the basket so that, in addition to sludge sediment, non-point source contaminants such as floating matters and foreign substances, such as leaves, cigarette butts, and trash, can be removed separately when they accumulate.

The purpose of the present invention is to provide an improvement in filtration efficiency during the process of filtering through a superior water treatment facility (sewage treatment plant or sewage treatment plant and then final discharge into a river).

In order to achieve this purpose, the present invention is formed such that a drainage hole (120) is formed on one side and the other side of a side wall of a rainwater collecting tank (100) equipped with a collection space (110) so that a water pipe (10) is connected, a mounting groove (130) is formed in the open upper part of the rainwater collecting tank (100) so that a steel grating (20) is installed, and a basket (200) is inserted or received into the water collecting space (110) so that it is mounted, but a communication hole (220) is formed on one side and the other side of the side wall of the basket (200) equipped with a collection space (210) so as to correspond to the drainage hole (120) of the rainwater collecting tank, and a hanging member (230) that rotates by a hinge member (231) is formed in the center of the inner surface of the basket (200) so that the basket (200) is hung when removing and recovering sludge. It is formed so that it can be separated by lifting upward from the superior receiving tube (100).

Accordingly, the basket (200) is formed so that a mesh basket (300) is installed in the collection space (210) to filter out non-point source pollutants (leaves, cigarette butts, trash, flyers, various floating non-point source wastes, etc.) other than sludge.

In addition, the basket (200) is formed with a detection rod (400) on one side so that when the water level inside the rainwater collecting tank changes due to the amount of sludge settling, the upper part of the detection rod (400) rises above the steel grating (20) (when the amount of sludge increases and the water level of the inflow water rises, it rises to indicate the state of sludge settling).

In this way, the present invention is installed on the road or sidewalk boundary (in a downtown residential area, park, highway or local road, and construction sites nationwide) to collect rainwater, and a cassette-type basket is inserted into a rainwater catcher, but when sludge is removed and recovered, the basket can be lifted from the rainwater catcher and simply separated, so that when the settled sludge accumulates, it can be collected and removed all at once (at one time or once).

This invention has the effect of fundamentally resolving the previous laborious work of having workers manually dig up soil one by one using shovels or scoops.

In addition, the present invention has the effect of ensuring rapid workability according to sludge treatment and significantly reducing work man-hours (no need for additional auxiliary materials), while also enabling smooth work, thereby preventing safety accidents and at the same time greatly reducing labor costs.

In particular, the present invention has the effect of significantly improving flood accidents caused by road flooding or rainwater backflow.

In addition, the present invention can be simply applied to existing rainwater collectors, and has the effect of enabling easy compatible application without replacing (replacing) the existing structure.

In addition, the present invention is easy to mount and dismount (install and separate for recovery), so it has excellent handling and management effects.

In addition, the present invention further installs a mesh basket inside the basket so that, in addition to sludge sediment, non-point source pollutants such as leaves, cigarette butts, and trash, such as floating matters and impurities, can be separately removed, which has the effect of improving filtration efficiency during the process of being filtered through a water treatment facility (after passing through a sewage treatment plant or sewage treatment plant and then finally being discharged into a river).

The present invention is described below with reference to the attached drawings.

First, as shown in FIGS. 1 and 2, the present invention is largely composed of a superior receiving container (100) and a basket (200) made of synthetic resin material.

Accordingly, a rainwater collection tank (100) equipped with a collection space (110) is formed with a drainage hole (120) formed on one side and the other side of the side wall so that a water pipe (10) is connected.

At this time, a mounting groove (130) is formed in the open upper part of the superior receiving tube (100) so that the steel grating (20) can be installed therein.

Additionally, a basket (200) is formed to be inserted or stored and mounted inside the collection space (110).

Accordingly, a basket (200) equipped with a collection space (210) is formed with a communication hole (220) on one side and the other side of the side wall to correspond to a drain hole (120) of a rainwater collection tank.

At this time, a hanging member (230) that rotates by a hinge member (231) is formed in the center of the inner surface of the basket (200) so that the basket (200) can be lifted upward and separated from the rainwater collection container (100) when sludge is removed and recovered.

For reference, the hanging member is positioned in the center of the basket, and a hinge member is formed on the side wall to allow 360° rotation, so that when the basket is lifted by a crane or other construction equipment, it rotates in one direction and tilts, allowing the contained sludge to be discharged.

At this time, the hanging member is formed so that a storage groove is formed in the open upper edge flange of the basket, and is normally placed in the storage groove in the form of a pocket, but is formed so that when the basket is lifted, it is lifted upward and outward through the hinge member while being detached from the storage groove.

Accordingly, as shown in FIGS. 3 and 4, the basket (200) is formed so that a mesh basket (300) is installed within the collection space (210) to filter out non-point source contaminants (leaves, cigarette butts, trash, flyers, various floating non-point source wastes, etc.) other than sludge.

That is, the mesh basket has a mesh net smaller than a cigarette butt formed on all four sides and the entire bottom surface, ensuring smooth drainage while providing excellent catchability.

Meanwhile, as shown in Fig. 5, the basket (200) is formed with a detection rod (400) on one side so that when the water surface inside the rainwater collecting tank changes due to the amount of sludge settling, the upper part of the detection rod (400) rises above the steel grating (20) (when the amount of sludge increases and the water surface of the inflow water rises, it rises to indicate it) so that the sludge settling state can be checked.

These detector rods are formed with a float at the bottom based on a vertically standing main shaft rod, and are formed so that the main shaft rod goes up and down along a slider rail (attached to the side wall of the basket).

That is, when the sludge settles and the water surface level of the rainwater contained in the basket rises, the main shaft rod rises through the slider rail according to the rising action of the float, and the upper end of the main shaft rod protrudes between the grills of the steel grating, forming a water level that can be visually confirmed.

At this time, it is desirable to install a waterproof, sealed LED lamp and a protective cap on the upper part of the main shaft so that when it protrudes through the steel grating, the sludge sedimentation status inside the basket can be quickly alarmed to nearby pedestrians or managers.

In addition, as a secondary embodiment, the basket of the present invention is preferably provided with a mesh screen (500) on one side (the inlet side through which rainwater is discharged) of the communication hole (220) as shown in FIGS. 6 to 9 to prevent submerged sludge or floating waste from being discharged into the waterway through the communication hole and drain hole.

These mesh screens are manually openable structures, and the mesh screens with a hinged structure (left and right symmetrical structure) can be opened or closed to adjust the degree of opening (open area) depending on the season or on-site conditions. Normally, they are completely closed to increase filtration efficiency, but in rainy weather, they are fully open to control the flow rate of the rainwater being drained so that it is not hindered.

Accordingly, the mesh screen (300) is largely composed of a mounting socket (510), a draw bar (520), a sill (530), and an elastic body for storage (540), and as shown in FIGS. 6 to 9, it is installed on the inner wall surface of the drain side of the communication hole so that the opened communication hole (220) can be manually opened and closed.

First, the mounting socket (510) is formed to be assembled in a sliding manner while corresponding to the inner groove (552) provided in the end portion (554) of the mesh plate (550).

Accordingly, the mounting socket (510) is formed with an insertion key (511) formed on one side to fit into a key insertion groove (553) formed on the inside of an insertion groove (552) to prevent it from falling out and to be inserted in a sliding manner.

In addition, the mounting socket (510) is formed so that a folded surface (512) is formed on the outer end opening side, an open groove (513) corresponding to the outer side facing the opening/closing end (551) is formed, and a guide rib (516) having a catch (515) on the inner wall (514) and a transfer section is provided.

Accordingly, the withdrawal bar (520) is formed with a support guide plate (522) having a catch (521: prevented from falling out by being caught by a catch (515) that acts as a stopper) on one end (the side facing the inner wall of the mounting socket) to facilitate withdrawal of the sill (530) while moving back and forth through the transfer section of the guide rib (516).

At this time, the support guide plate (522) including the latch is formed symmetrically with respect to the guide rib, and an opening (523) is formed on the opening/closing side.

For reference, the mounting socket (510) including the withdrawal bar (520) is formed in the form of an elongated stick bar having a longitudinal direction so that it can be inserted and assembled in a sliding structure in one direction from the side of the opening/closing end, thereby facilitating exchange and replacement.

In addition, the sol-mak (530) is formed so that a fixed gasket (532) with mo-pils (531) planted on the opening (523) side between the support guide plates is combined (bonded or pressed).

Accordingly, a magnetic bar (533: a neodymium magnet with an ultra-strong magnetic force, etc./not attached or in close contact with an opposing iron plate or magnetic bar_pulls its own pine block outward together with the fixed gasket including the opposing pine block by magnetic force in a state of non-contacting air) is formed to be attached and combined at the rear end of the fixed gasket (532).

In other words, the mesh screen (500) is equipped with a double-door mesh plate (550), and is formed so as to ensure the flow of water even when a plurality of sluice gates (530) completely close the opening and closing ends, while filtering out floating contaminants.

Accordingly, the mesh plate (550) is formed to open and close symmetrically with respect to the center point of the communication hole (220).

At this time, a support plate (570) is formed on one side of the rear end of the mesh plate (550). The support plate is a pocket-shaped door frame through which the mesh plate (550) is formed to open and close by sliding left and right based on the center point of the communication hole.

Accordingly, the mesh plate (550) is formed with a sill (530) on the side of the facing end (554) toward the opening/closing end (551) to ensure that the flow of water is induced smoothly together with the mesh plate, but is formed to prevent floating sludge or non-point source pollutants (such as cigarette butts, leaves, or trash) from being drained into the waterway.

In addition, the sol-mak (530) is installed symmetrically on each of the two end portions (554) of the mesh plate (550) symmetrically based on the opening/closing end (551), and when the opening/closing end (551) is formed at a predetermined interval while built into the mounting socket (510) and not in complete contact with each other, the sol-mak (530) is formed to be inserted/extracted while responding to each other by the magnetic force of the magnetic bar (533) provided on the rear side of the sol-mak (530).

And, the elastic body (540) for storage is formed so that a through hole (541: outside) and a through tube (542: inside) are formed in parallel on the same axis on the folded surface (512) of the mounting socket, and when a tension member (543: elastic spring) is inserted from the outside, the support guide plate (522) of the pull-out bar is pressed against the pull-out bar to push the pull-out bar (520) into the inside of the mounting socket (510) (elasticity is provided so that the pull-out bar (520) is constantly pushed toward the inner wall of the mounting socket (510).

Accordingly, the through hole (541) is filled with an assembly screw (544: headless bolt), and the supporting force on the opposite side of the tension member (543) is formed through the inner surface of the assembly screw (544).

At this time, the head bolt is formed to enable through-hole and screw-fastening assembly, and is easy to replace when the elasticity of the tension member (543) stored through the through-hole decreases (when the elasticity decreases due to lifespan).

In other words, the mesh screen (500) is formed to prevent sludge or floating waste matter submerged in the basket from being discharged into the water channel through the connecting hole and drain hole.

The present invention is not limited to the specific preferred embodiments described above, and anyone with ordinary skill in the art to which the present invention pertains may make various modifications without departing from the gist of the present invention claimed in the claims, and such modifications are within the scope of the claims.
