Abstract

The present invention relates to a device for preventing the inflow of foreign substances into the sewer to filter and collect the cigarette butts and other wastes that are introduced into the rain gutter manhole installed around the driveway or sidewalk.

In general, when the rain falls or the rain pipes are gradually blocked by the foreign matters wrapped from the inside of the manhole, when the rain or rainy season rains down a lot, the drain holes of the manholes are blocked, thus causing considerable damage.

The present invention relates to a product designed to easily collect and dispose of small garbage as a component configuration to prevent such damage in advance.

Description

Device for preventing the inflow of foreign substances into sewers {omitted}

The present invention relates to a rain gutter manhole device for inducing rain flows to be discharged through the sewer.

If you look at the structure of the conventional manhole has been made to install the rainwater inlet pipes by attaching the angle produced in the form of a gap in the upper end of the construction pipe simply made of a concrete rainwater inlet pipe.

However, this method has been used only as a means of preventing safety accidents that may occur around roadways or sidewalks. Garbage flowing in with a large amount of rainwater flows into the sewers, which causes clogging of the sewers, causing rainwater to flow back, and there is always a situation in which damage can occur.

In addition, as a method for filtering foreign matter introduced with rainwater, there was a case that is used to install the upper and lower cross-sections of the sewer angle part using simple wire meshes, but the use is very inconvenient and it has not been used now.

Wire mesh and rainwater outflow devices as a method for filtering foreign matter (hereinafter referred to as "small garbage") that can be installed in synthetic resin rain gutter manholes or manholes of non-concrete concrete products, which have been pointed out to solve the problems described above. The device is designed to be used at the same time by installing a sphere, but sometimes it can be used only by installing a rainwater drainage device even when the wire mesh is removed.

In the apparatus for preventing foreign matter inflow, which is composed of a main body 21, a wire mesh 22, and a rotation rod 23, first, the main body 21 has a rectangular shape with respective inner protruding holes on both sidewalls of which the inner side is perforated. (24) and stoppers (25) (25 ') and the projections (26, 26') perforated around the upper side wall side, and is formed by speech forming the fixing pieces (33, 33 ') around the upper side wall outer periphery. At one end of the front and rear ends, the support pieces 35 are configured to be bent inwardly in accordance with the respective arrangements.

The wire mesh 22 has a handle attached to the center portion as shown in the drawing, and the rotating rods 23, 23 'and 23' are semicircular supporting protrusions 27 (2) on both side surfaces as bending structures of the long grooves. 27 ') to be insulated, and the bent insert insertion pieces 29 and 29' are formed at the front end and the rear end.

Referring to the assembly configuration and the operating state of the present invention configured as described above are as follows.

A metal plate material is formed in the groove shape at the center of the support protrusion pieces 27 and 27 'during the rotation of the protrusion holes 24 and 24' formed on the back surface of both sides of the main body 21 drawn by press-pushing. After inserting the pins 30 and 30 'into each of the fitting holes 28 and 28', which are drilled, the rivets are inserted and riveted so as to have rotational force 23, 23 'and 23'. The stoppers 25 and 25 'at a constant angle to allow them to be assembled at a stationary position so that the (23' ') is assembled and the center of gravity of the rotation 23 is biased in the rearward direction. It can be molded and constructed.

This is because the amount of rainwater flowing in, i.e. the weight of rainwater flows, so that the front end of the rotation 23 is curved to form a downward direction by the central axis, thereby giving an action force to gently inflow the rainwater. will be.

In addition, as the inflow rate of the rain decreases, the rotation center 23 maintains the weight center by the protruding stopper 25 when it maintains the equilibrium, and is supported in the center as shown in FIG. 4. One way is to be grounded in both directions about the liver 36, 36 '.

In this simple configuration, the fixing pieces 33 and 33 ', which are the upper wing portions of the main body 21, are angled 38 which are internally mounted on the upper ends of the concrete manholes 51 and 51' held by the ground 53. (38 ') is provided to be attached to the lower peripheral portion of the peripheral portion or is configured to be installed in a manhole formed in a step layer, and a stone piece (26) to allow the wire mesh 22 to be seated on the main body 21 ( 26 ') can be used even if the wire mesh is removed if necessary.

Unexplained code 31,37 is a hole 32 is a handle 39 is an inlet.

The device structure of the present invention configured as described above can not be stacked in the manhole primarily in the wire mesh 22, even if cigarette butts or other wastes, which are mainly discarded on a clear day, pass through the wire mesh by the rotating shaft 23. Since it is configured to prevent foreign matter from passing through the manhole, it is given the advantage that it is easy to collect the stacked garbage before it rains, and also has the advantage of preventing the inflow of soil.
