Description

Flow gate for sewers with excellent odor blocking function {FLOW GATE OF MANHOLE}

The present invention relates to a flow gate for a sewer. When the drainage function of the sewer manhole is not smooth due to piled up leaves, etc., drainage is performed through the flow gate located on the side of the sewer manhole, and furthermore, it is provided with a blocking plate and a structure that allows stable close contact. This relates to a flow gate for sewers that has a function that can effectively block bad odors from rising.

Generally, drainage structures are installed on roads or pavements to discharge rainwater or sewage. The drainage structure is connected to a sewer pipe buried underground and transports collected rainwater or sewage to a sewage treatment plant or river. A lattice structure, also called 'steel grating', or sewage manhole, is installed in the open upper part of the drainage structure to remove large and rough foreign substances. Filter it out.

However, when fallen leaves and other foreign substances accumulate on the top of the sewer manhole, it becomes difficult to perform the function of drainage, causing problems such as water backflow and overflow on the road.

To solve this problem, a variety of technologies have been proposed to prevent trash from accumulating in sewer manholes or covers, and the related technology is registered patent number 10-1335863, “Odor blocking device with garbage input prevention function for sewer manholes.” 」, Registered Utility Model No. 20-0268563 「Device for preventing foreign substances from entering sewer」.

The above prior art relates to a technology to prevent foreign substances from entering the drain, or simply to filter out foreign substances, but ultimately has the same problem in that the drainage function is not achieved when foreign substances such as fallen leaves accumulate. there is.

Meanwhile, a conventional technology that allows drainage of rainwater even when fallen leaves, etc. are accumulated, includes Publication Patent No. 10-20096-0017869 “Boundary block with attached water gate.”

Publication Patent No. 10-20096-0017869 forms a boundary block drain through which rainwater can flow in by forming a groove of a certain size inside the boundary block, and the formed boundary block drain is connected to a drain pipe on one side and is connected to another side of the drain pipe. One side is connected to the water collection well so that rainwater flows into the water collection well. Even if the grating of the water collection basin is clogged with foreign substances such as fallen leaves, vinyl, or boxes, the rainwater is allowed to drain through the boundary block where the drain is formed, so that it does not flow into the road or residential area. A configuration is proposed to prevent flooding.

In particular, Publication Patent No. 10-20096-0017869 proposes a structure in which a water gate is installed in the drain, which is normally closed to prevent the inflow of trash or soil, but when the drain is blocked, the water gate opens due to the water pressure of rainwater and drains the rainwater. .

However, looking at the structure of the water gate and boundary block proposed in Publication Patent No. 10-20096-0017869, there is a limit to the water gate being in close contact with the boundary block, so it has a limitation of not being able to block the odor coming from the sewer, and the 50mm ledge Due to this, there is a problem of causing black ice in the winter due to stagnant water or melting snow.

In other words, in the case of conventional sewer manholes, covers are installed arbitrarily to block sewer odors, which causes problems with drainage. Although odor blocking devices are installed at the bottom of the steel grating to block odors, drainage is blocked due to failure or loss due to foreign substances. It is causing enormous trouble, and Patent Publication No. 10-20096-0017869 also has limitations in blocking odor.

Since road facilities are constantly exposed to the external environment and used by an unspecified number of people, the development of simple products has the characteristic of providing superior performance in extreme situations rather than power or mechanical devices.

The present invention is intended to complement the problems of the prior technologies described above. It prevents road flooding in the summer by preventing small water accumulations in sewage manholes due to debris such as fallen leaves, as well as black ice caused by melting snow due to temperature changes between day and night in the winter. The purpose is to propose a flow gate that has the function of efficiently blocking odors rising from the sewer while proposing a structure that does so.

Of course, in implementing the above-mentioned functions, the goal is to provide a simple structure that is not complicated, that is, to provide a flow gate that can increase product competitiveness by simplifying the structure so that there is no failure even in the extreme external environment of all four seasons.

The flow gate for sewers according to the present invention for achieving the above object,

A first pipe body forming an inlet located on the upper side of the sewer on the front, and fluid flowing in through the inlet;

In the flow gate for a sewer, including a second pipe body, one end of which communicates with the first pipe body and the other end of which communicates with a sewer, allowing fluid flowing in from the first pipe body to drain into the sewer,

The front of the first pipe body is made of an inclined surface that is recessed inward from the top to the bottom,

It is characterized in that a blocking plate is provided located inside the inlet and installed so that an end extends over the front surface.

In addition, the flow gate for a sewer according to the present invention is further provided with a bracket for mounting the blocking plate to the inside of the front of the first pipe body,

The bracket is characterized in that it consists of a fastening part for bolting fastening to the front, and a pressing part that is formed in a bent state at the fastening part and presses the blocking plate in the front direction.

And the blocking plate is characterized in that it is an elastomer plate.

Meanwhile, in the flow gate for a sewer according to the present invention, the inlet is provided with support ribs that vertically support the top and bottom of the inlet,

The blocking plate is characterized in that a vertically cut slit is formed at a position corresponding to the support rib.

According to the flow gate for sewer according to the present invention having the above configuration,

Even if foreign substances such as fallen leaves are piled up in the sewer manhole and drainage through the sewer manhole is not possible, drainage is done through the inlet formed on the side of the sewer manhole, preventing small water stagnation. In addition, when drainage is not necessary, a blocking plate is attached to the first pipe body. By maintaining the condition, it is possible to effectively block bad odors coming from the sewer.

In particular, the sloping structure of the front of the first pipe causes the ground connected to the sewer manhole to be inward compared to the neighboring road curb, which can be expected to have the effect of blocking odor and facilitating water collection toward the flow gate when draining water. there is.

In addition, by proposing a simple structure, product competitiveness can be secured by lowering production costs while providing excellent functionality.

1 is a diagram showing a state in which a flow gate according to the present invention is installed.
Figure 2 is an operational diagram of the flow gate according to the present invention.
Figure 3 is a diagram showing a flow gate according to the present invention.

Hereinafter, a flow gate for a sewer having an excellent odor blocking function according to the present invention will be described with reference to the drawings.

The present invention prevents black ice in the winter by enabling drainage even when foreign substances such as fallen leaves are accumulated on the sewer (H), or more precisely, on the upper part of the sewer manhole (M), by creating a structure that allows flooding of roads and small water accumulations to be easily drained. In addition, it is characterized by a flow gate (G) that can create a pleasant street environment by blocking bad odors rising from the sewer (H).

First, referring to FIGS. 1 and 2, the flow gate (G) according to the present invention is,

A first pipe body (10) forming an inlet (10a) at the front, through which fluid (i.e. rainwater or sewage, hereinafter referred to as 'rainwater') flows in and flows;

It includes a second pipe body (20), one end of which is in communication with the first pipe body (10) and the other end of which is in communication with a sewer, allowing rainwater flowing in from the first pipe body to drain into the sewer.

The inlet (10a) is located on the upper side of the sewer, and is usually located on the side of the sewer manhole (M). In one embodiment, as shown in FIG. 1, a portion of the road curb is removed, the flow gate (G) of the present invention is installed, and the inlet is located on the side of the sewage manhole (M).

Next, the front 11 of the first tube body 10 is in the form of an inclined surface that is recessed inward from the top to the bottom. As can be seen in Figure 2, the distance between the front and back of the first tube body is lower than the upper part. It is formed briefly (d1>d2).

In addition, a blocking plate (30) is installed on the inside of the inlet, which is lifted to open the inlet when draining rainwater and closes the inlet when drainage is not needed to block bad odors rising from the sewage.

The blocking plate 30 is installed inside the first pipe body with a size that allows its ends (lower end and both side ends) to span the front of the first pipe body.

In particular, since the front surface 11 of the first pipe body is an inclined surface that is recessed inward from the top to the bottom as described above, the blocking plate 30 can easily come into close contact with the inside of the front surface due to its own weight.

That is, if the front of the first pipe is a vertical surface rather than an inclined surface, the blocking plate is not always in close contact with the inside of the front (due to limitations in construction, etc.) and the lower end has a gap and is lifted. In the present invention, the front of the first pipe (11) This problem was easily solved by making it an inclined surface, and the end of the blocking plate was placed across the front so that it could be maintained in close contact unless a special external force such as rainwater inflow was generated.

In addition, the blocking plate 30 is preferably an elastomer plate with flexibility to maintain close contact and be easily lifted when rainwater flows in. A rubber plate may be considered as an example.

In addition, the inclined structure of the front of the first pipe of the present invention can be expected to not only allow the blocking plate to be closely adhered to the inside of the front, but also facilitate water collection.

In other words, by forming the front surface 11 of the first pipe slanted in a shape that is recessed inward from the top to the bottom, the ground connected to the sewer manhole is in a state of being recessed inward compared to the neighboring road curb, creating an inward space (S) This formation facilitates water collection toward the flow gate as drainage progresses.

Next, the present invention proposes a bracket 40 of a separate structure for fastening the blocking plate 30 to the first pipe body.

That is, the bracket 40 of the present invention is designed to install a blocking plate on the front of the first pipe body and to maintain a more stable close contact by pushing the blocking plate to the front of the first pipe body,

The bracket 40 mounts the blocking plate on the front through bolting with the front, and includes a fastening part 41 in the form of a plate with a bolt fastening hole formed at the top, and a blocking plate formed in a bent state at the fastening part. It consists of a pressing part 42 that presses in the front direction.

A hinge-like structure can be considered for the rotation of the barrier plate, but due to the nature of the road, which is exposed to the external environment and surrounding impurities all year round, the known hinge structure has limitations in allowing the barrier plate to be easily lifted and maintained in a fixed state, thereby blocking odor. In this case, the known hinge structure is not efficient.

Accordingly, in the present invention, when sewage flows in, the blocking plate, which is a rubber plate, can be easily lifted, but when sewage does not flow in, the blocking plate can be adhered to the inside of the front of the first pipe body, and further, the blocking plate can be easily attached to the first pipe body. A bracket structure similar to that in the present invention that allows fastening has been proposed.

Therefore, through the bracket, the operator can easily install the blocking plate on the front of the first pipe body by bolting, and when the fastening part of the bracket is installed and fixed on the blocking plate by bolting, the pressing part is formed by bending to one side at the end of the fastening part. As a result, the gap between the fastening part and the blocking plate widens toward the bottom, which creates a force that presses the blocking plate in the front direction when the presser touches the blocking plate, allowing the blocking plate to remain in close contact with the inside of the front more stably. do.

Next, it is preferable that the inlet (11a) of the present invention is provided with support ribs (50) that vertically support the top and bottom of the inlet.

The support rib 50 is a structural material that can withstand a strong load that is suddenly generated on the flow gate, and the flow gate of the present invention is installed to replace a part of a normal road curb. There may be cases where a vehicle rides on a road curb or flow gate, and the structure is designed to ensure that the flow gate can withstand strong loads in such situations.

In addition, the blocking plate 30 is formed with a vertically cut opening 32 at a position corresponding to the support rib, which has the effect of dividing the blocking plate into two so that each can be lifted based on the opening when sewage flows in. .

In addition, for the convenience of construction, a construction handle (60) of a certain size is installed on the rear of the floor gate to prevent loading/unloading of the product and poor construction.

In the above description of the present invention, the flow gate for sewers having a specific shape, structure, and configuration has been mainly described with reference to the accompanying drawings. However, the present invention can be modified, changed, and replaced in various ways by those skilled in the art, and such modifications and changes can be made. and substitution should be construed as falling within the protection scope of the present invention.
