Description

RAINWATER COLLECTOR FOR PREVENTING INFLOW IN SEWAGE AND BAD SMELL}

The present invention relates to a rain gutter to prevent dirt inflow and odors, and more specifically, to prevent the inflow of sewage and odors and at the same time, to prevent the inflow of sewage pipes and various sewage and foreign substances mixed in the sewage. It relates to rain gutters to prevent odors.

Manholes are installed on the side of the road to discharge rainwater and sewage. Manholes are connected to sewer pipes buried underground. Therefore, the collected rainwater or sewage is transferred to a sewage treatment plant or a river.

On the other hand, a grating structure, also called "steel grating", is installed on the open upper part of the manhole to filter large and coarse foreign matter.

However, these manholes and sewage pipes have a problem of allowing backflow of sewage when heavy rain or rainy season prevents the discharge of sewage smoothly. In particular, there is a problem of polluting the road by discharging the reversed sewage as it is on the road.

In addition, the conventional manholes and sewage pipes have a problem that the odor of the sewage flowing along the inside is reversed. In particular, there is a problem of polluting surrounding air by releasing backflow odor into the atmosphere.

In view of this, a "sewage and odor backflow prevention device" for preventing backflow of sewage and odors has been developed.

This technique, as shown in Figure 1, by installing a pair of doors (3) facing each other on the sewer passage (1), when the sewage is introduced to open the sewer passage (1), It is configured to block the sewer passage 1 when the introduction is stopped or when the sewage flows back.

Such a prior art prevents the backflow of sewage at the source even if the sewage flow is closed when the sewage flows back, even when heavy rain or rainy season makes it difficult to discharge the sewage.

Moreover, when there is no discharge of sewage, it is comprised so that a passage | path may be closed and the odor of the sewage which flows along a sewer pipe is blocked back. This prevents backflow odors from being released into the atmosphere.

By the way, such a conventional technique has the advantage of preventing the backflow of rainwater, sewage and odor, but it is passed through various kinds of dirt and foreign substances introduced with rainwater, sewage, etc., such as cigarette butts, garbage, plastic bags, etc. There are disadvantages.

And because of these disadvantages, various problems and foreign matters (hereinafter, referred to as "dirt") is pointed out that the problem is mixed with rainwater, sewage flow into the sewer pipe underground. In particular, it has been pointed out that various wastes are mixed with rainwater and sewage and flow into underground sewer pipes, thereby obstructing underground sewer pipes.

The present invention has been devised to solve the above-mentioned conventional problems, the purpose of which is to prevent the backflow of sewage, and at the same time to prevent the backflow of odor generated therefrom rainwater gutter to prevent the inflow of odor and odor To provide.

Another object of the present invention is to provide a rain gutter to prevent the inflow of filth and odor that can block the inflow of sewage pipes by the configuration to be able to filter the various wastes flowing in with rainwater, sewage and the like.

Another object of the present invention is to provide a rain gutter to prevent the inflow of filth and odor that can prevent the clogging of the sewage pipe due to the inflow of the source by blocking the inflow of the sewage pipe of the source.

In order to achieve the above object, the present invention, in the rain gutter to prevent the dirt inflow and odor installed in the sewer manhole, the main body having a first and second passage for introducing and discharging sewage; A first door to open the first passage when the sewage is drained in the forward direction to the first passage, and to close the first passage when the sewage flows back from the first passage; A second door which opens the second passage when the sewage is drained in the forward direction to the second passage, and closes the second passage when the sewage flows back from the second passage; Elastic pressing means for elastically pressing the first door in a closed position direction so that the first passage can be opened only when the flow pressure of the sewage introduced into the first passage is equal to or greater than a set pressure; And a collecting network installed on the second passage so as to collect the dirt in the sewage passing through the second passage.

According to the rain gutter to prevent dirt inflow and odor according to the present invention, when the sewage is introduced into the passage, the passage is opened and discharged, and when the discharged sewage and odor flows backwards, the passage is closed, While preventing the reverse flow of sewage, there is an effect that can prevent the reverse flow of odor generated from the sewage.

In addition, since the present invention can prevent backflow of sewage and odors, there is an effect that can prevent property damage caused by backflow of sewage and odors.

In addition, the present invention, because it is a structure that can filter various kinds of waste, garbage flowing in with rain water, sewage, etc., it is possible to block the inflow of sewage pipes and waste. Therefore, it is possible to prevent clogging of the sewage pipe due to the inflow of dirt and waste. As a result, there is an effect that can significantly reduce the manpower, time and costs required for cleaning the sewer pipe.

In addition, since the present invention is configured to collect various wastes and wastes to one side, the collected wastes and wastes can be cleaned by a vacuum cleaner, and thus the wastes and wastes can be cleaned without opening the upper lattice structure. . Therefore, it is easy to manage the waste and waste, and it is possible to drastically reduce the manpower, time and cost required for cleaning the waste and waste.

In addition, the present invention, since the structure can be additionally installed in the existing manhole, it is possible to give the existing manhole to prevent the inflow of dirt and backflow of sewage and odor. Therefore, it is not necessary to newly install a manhole having a function of preventing inflow of dirt and backflow of sewage and odors. As a result, the cost reduction effect can be expected.

Hereinafter, a preferred embodiment of the rain gutter to prevent dirt inflow and odor according to the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a perspective view showing the configuration of the rain gutter to prevent dirt inflow and odor according to the present invention, Figure 3 is a cross-sectional view showing a rain gutter is installed in the manhole preventing dirt inflow and odor according to the present invention.

First, referring to Figures 2 and 3, the rain gutter of the present invention, has a main body (10).

The main body 10 is attached to the upper part of the manhole A1 embedded in the ground A. FIG. In particular, the main body 10 is seated on the stepped portion A2 formed around the upper opening of the manhole A1, and thus the main body 10 may be additionally mounted on the inner passage A3 of the existing manhole A1.

The main body 10 is composed of a rectangular tube body and has an internal main passage 12. The main passage 12 includes an upper inlet 14, first and second branch passages 16 and 18 branched from both sides of the inlet 14, and first and second branch passages 16 and 18. It consists of the lower outlet 19 in communication with.

The inlet 12 is for introducing rainwater and sewage (hereinafter referred to as "sewage"), and a lattice structure B is placed on the upper side thereof.

The first and second passages 16 and 18 are moving passages of the sewage introduced into the inlet 12 and are formed toward the outlet 19. Here, the first passage 16 is preferably larger and wider than the second passage 18.

The outlet 19 is connected to the sewer pipe 19a of the manhole A1, and discharges the sewage transferred along the first and second passages 16 and 18 to the sewer pipe 19a.

The main body 10 is preferably made of a material having high strength, for example, iron material.

2 and 3 again, the rain gutter of the present invention includes a first door 20 for opening and closing the first passage 16.

The first door 20 is rotatably installed inside the first passage 16 about the hinge portion 20a.

The first door 20 rotates by the flow pressure of the sewage introduced into the first passage 16. In particular, when the flow pressure of the introduced sewage is more than the set pressure, the first passage 14 is opened while rotating to the open position V by the flow pressure of the sewage. Thus, the discharge of sewage is allowed.

On the contrary, when the flow of sewage introduced into the first passage 16 is less than the set pressure or when no sewage is introduced, the first door 20 is closed by the elastic pressing means 24 described later. The first passage 16 is closed while returning to.

Moreover, when the sewage flows backward, the first door 20 is configured to close and close the first passage 16 while rotating back to the closing position W by the pressure of the sewage flowing in the reverse direction. Thus, the reverse flow of sewage is blocked.

On the other hand, the elastic pressing means 24 which elastically presses the first door 20 in the closing position (W) direction is a kind of leaf spring whose one end portion 24a is fixed to the inner wall of the first passage 16. The terminal portion 24b presses the first door 20. In particular, it presses elastically to the closing position (W) direction.

Therefore, when the elastic pressure means 24 has no sewage introduced into the first passage 16 or the amount of sewage introduced into the first passage 16 is small and its flow pressure is not greater than its elastic force (set pressure). In addition, the first door 20 is elastically pressed in the closing position W to close the first passage 16.

In some cases, the elastic pressing means 24 may be formed of a torsion spring of a coil type. In this case, the torsion spring is installed in the hinge portion 20a of the first door 20.

On the other hand, when the first door 20 is rotated to the closed position W and the first passage 16 is closed, the first door 20 is configured to be inclined toward the second passage 18.

When the sewage water of less than the set pressure is introduced into the first passage 16, the sewage introduced into the first passage 16 is closed while the first passage 16 is closed. This is to guide the furnace, and to discharge the sewage while opening the first passage 16 only when a large amount of sewage is introduced.

In addition, the first door 20 further includes a magnet 26 provided at the distal portion. The magnet 26 is configured to be attached to the peripheral portion 16a of the first passage 16 when the first door 20 is rotated to the closed position W to close the first passage 16.

Thus, the first door 20 can be maintained in the closed position (W) state. As a result, even if the elastic force of the elastic pressing means 24 is reduced to reduce the bearing force on the first door 20, the first door 20 is maintained in the closed position (W) instead. Here, the attachment force of the magnet 26 to the peripheral portion 16a of the first passage 16 should be equal to the elastic force of the elastic pressing means 24.

On the other hand, when the first door 20 is rotated to the open position (V), the magnet 26 of the first door 20 may be attached to the inner wall portion 16b of the first passage 16, In the inner wall portion 16b of the first passage 16 corresponding to the magnet 26, an auxiliary magnet 28 for generating repulsive force with the magnet 26 is further provided.

The auxiliary magnet 28 is installed to have the opposite polarity with the magnet 26 of the first door 20, and the magnet 26 and the repulsive force are generated to connect the magnet 26 and the first door 20. Push in the closing position (W). Therefore, it helps to rotate the first door 20 to return to the closed position (W).

2 and 3 again, the rain gutter according to the present invention includes a collecting network 30 installed in the second passage 18.

The collecting network 30 is installed to block the second passage 18 and serves to collect various wastes and wastes in the sewage flowing into the second passage 18.

In particular, by collecting various wastes and wastes in the sewage, the collected various wastes and wastes are not discharged to the sewer pipe 19a of the manhole A1. This prevents clogging of the sewage pipe 19a which occurs as various wastes and dirt enter the sewage pipe 19a.

The collection network 30 is configured in the form of a rectangular bag to collect a lot of dirt and waste. And the material of the collecting network 30 is composed of a wire mesh. Of course, it is also possible to be composed of a synthetic resin network.

And the collecting network 30 is configured to insert a vacuum cleaner (C) through the upper grid structure (B), it is possible to suck various wastes and garbage collected using the vacuum cleaner (C) inserted in this way. To be able. As a result, it is easy to collect the collected dirt and garbage. This significantly reduces the collection time of waste and garbage, and greatly reduces the manpower required for waste collection.

Meanwhile, the collecting network 30 may be configured to be pulled out through the inlet 14 of the main passage 12. Therefore, it is possible to shake off various collected wastes and garbage by hand.

2 and 3 again, the rain gutter according to the present invention further includes a second door 40 installed downstream of the collecting network 30.

The second door 40 is constituted by a pair of door plates 42 which are installed to face each other on the second passage 18.

The pair of door plates 42 are rotatably installed around the hinge portion 42a, and are installed in a "Ｖ" shape to face each other.

These door plates 42 open the second passage 18 while rotating to the open position X on the outside by the flow of sewage introduced into the second passage 18, and when there is no discharge of sewage, It is comprised so that the said 2nd path 18 may be closed, rotating backward to the closing position Y by the weight 46b mentioned later. In addition, when the sewage flows back, it is configured to close the second passage 18 by closing the reverse passage to the closing position Y by the sewage flowing in the reverse direction.

According to the second door 40, when the sewage is drained in the forward direction, the second passage 18 is opened to facilitate the discharge of the sewage, and when the sewage flows in the reverse direction, the second passage 18 It is configured to close it. Therefore, even in case of heavy rain or rainy season, it is possible to prevent backflow of sewage even when the sewage is not discharged smoothly.

In addition, when there is no discharge of sewage, the second passage 18 is closed, thereby preventing the odor of the sewage flowing along the sewer pipe from flowing back, thus preventing the reversed odor from being released into the atmosphere.

On the other hand, the door plate 42 of the second door 40 is supported by the stopper 44 and is prevented from being rotated further upward from the closing position Y. Therefore, both door plates 42 may face each other at the closed position Y and may maintain a "Ｖ" shape. In particular, it is possible to close the second passage 18 while maintaining the "Ｖ" shape.

On the other hand, the second door 40 further includes a return means 46 for returning each of the door plates 42 to the closed position Y. FIG.

The return means 46 is an extension piece 46a which protrudes in the opposite direction of the door plate 42 from the hinge portion 42a of the door plate 42, and a weight 46b provided on the extension piece 46a. It is composed of In particular, the weight 46b has a predetermined weight, and serves to pull the extension piece 46a in the direction of gravity. Therefore, the door plate 42 always serves to press the closing position (Y) direction.

According to such a return means 46, the door plate 42 is always pressed in the closing position Y direction, so that there is no inflow of sewage into the second passage 18, that is, no discharge of sewage. It serves to return the plates 42 to the closed position (Y). Therefore, it is possible to always close the second passage 18.

Next, an operation example of the present invention having such a configuration will be described with reference to FIGS. 4 to 6.

First, referring to Figure 4, looks at the case where a small amount of rainwater and sewage flows. A small amount of rainwater and sewage flows into the inlet 14 of the main passage 12 through the grid structure (B).

Then, the rainwater and sewage which flowed in are conveyed toward the 1st and 2nd channel | paths 16 and 18. FIG. At this time, if the flow pressure of the rainwater and the sewage flowing into the first passage 16 is less than the set pressure (elastic force of the elastic pressing means 24), the first door 20 is kept in the closed state in the first passage ( Guide rainwater and sewage transferred to 16) to the second passage (18).

Therefore, both the rainwater and the sewage introduced into the inlet 14 of the main passage 12 are introduced into the second passage 18, and the introduced rainwater and the sewage pass through the second passage 18.

On the other hand, the rainwater and sewage passing through the second passage 18 passes through the collecting network 30, and various kinds of dirt contained therein are filtered out. Then, the rainwater and sewage filtered through the dirt pass while opening the second door 40, and the rainwater and sewage passed through the outlet 19 are discharged into the sewer pipe 19a of the manhole A1.

Next, with reference to Figure 5, looks at the case where a large amount of sewage flows. First, a large amount of rainwater and sewage flows into the inlet 14 of the main passage 12 through the grid structure (B).

Then, the rainwater and sewage which flowed in are conveyed toward the 1st and 2nd channel | paths 16 and 18. FIG. At this time, when the flow pressure of the rainwater and sewage flowing into the first passage 16 is greater than the set pressure (elastic force of the elastic pressing means 24), the rainwater and the sewage flowing into the first passage 16 are the first door ( 20 is passed while opening, and the rainwater and sewage passing through is discharged to the sewer pipe 19a of the manhole A1 through the outlet 19.

And the rainwater and sewage which flowed into the 2nd channel | path 18 pass through the collection network 30 similarly to the above, and the various dirt contained in it is filtered. Then, the rainwater and sewage filtered through the dirt passes while the second door 40 is opened, and the rainwater and the sewage passed through the outlet 19 are discharged to the sewer pipe 19a.

Next, referring to FIG. 6, a case where a large amount of filth and garbage are collected in the collecting network 30 of the second passage 18 will not be described.

First, when a large amount of filth and trash is collected in the collecting network 30, when rainwater and sewage are introduced, the rainwater and sewage introduced are not smoothly drained due to the filth and trash collected in the collecting network 30. Therefore, the introduced rainwater and sewage are continuously stored at the inlet 14 of the main passage 12.

At this time, when the rainwater and sewage pressure stored in the inlet 14 of the main passage 12 is greater than the set pressure (elastic force of the elastic pressing means 24), the rainwater and sewage of the inlet 14 is the first door 20 ) Is passed while opening, the rainwater and sewage passed through the outlet 19 is discharged to the sewer pipe (19a) of the manhole (A1).

Therefore, rainwater and sewage flowing into the inlet 14 of the main passage 12 are smoothly discharged even if the second passage 18 is blocked.

According to the present invention having the above configuration, when the sewage is introduced into the passage, the passage is opened and discharged, and when the discharged sewage and odor are reversed backwards, the passage is closed, thereby preventing backflow of the sewage. At the same time to prevent backflow of odor from sewage.

In addition, the present invention can prevent backflow of sewage and odors, and thus prevent damage to property caused by backflow of sewage and odors.

In addition, the present invention, because it is a structure that can filter various kinds of waste, garbage flowing in with rain water, sewage, etc., it is possible to block the inflow of sewage pipe (19a) of the waste and garbage. Therefore, clogging of the sewage pipe 19a due to the inflow of dirt and waste is prevented. As a result, the manpower, time, and cost required for cleaning the sewer pipe 19a are greatly reduced.

In addition, since the present invention is configured to collect various wastes and wastes to one side, the collected wastes and wastes can be cleaned by a vacuum cleaner (C), so that the wastes and wastes are not opened without opening the upper lattice structure (B). Garbage can be cleaned. Therefore, it is easy to manage the waste and waste, and greatly reduces the manpower, time and cost required to clean the waste and waste.

In addition, the present invention, since the structure can be additionally attached to the existing manhole (A1), it is possible to give the existing manhole (A1) to prevent the inflow of dirt and backflow of sewage and odor. Therefore, it is not necessary to newly install the manhole A1 having the function of preventing the inflow of dirt and the reverse flow of sewage and odor. As a result, the cost reduction effect can be expected.

Next, FIG. 7 is a view showing another embodiment of the rain gutter according to the present invention.

The rain gutter of another embodiment has a structure which is integrally installed in the inner passage A3 of the manhole A1.

That is, on the first and second passages 16 and 18 branched from the entrance side of the manhole A1, the first door 20 to open and close the first passage 16, and the second passage 18, respectively. The trapping net 30 to be installed, the second door 40 for opening and closing the second passage 18, and the elastic pressing means 24 for elastically pressing the first door 20 in the closing position W direction and the like. Equipped with.

Each of these components has the same configuration and operation as described above. And all other parts have the same configuration and operation as the above-described embodiment. However, the main body 10 in the above-described embodiment becomes the manhole A1 in another embodiment.
