Description

Automatic opening device for manhole}

The present invention relates to a manhole for blocking odor and backflow of sewage, and more specifically, the body is fastened to the lower part of the manhole and a blocking plate which can be opened and closed automatically on both sides of the main body is normally closed and flows in from the outside. It relates to a manhole automatic opening and closing mechanism configured to be opened in accordance with the weight of the flowing water.

In general, due to the inflow of various sewage and organic matter, including domestic sewage in the sewage manhole, corruption proceeds in the drainage process. In particular, during the humid and high temperature seasons such as summer, the decay rapidly causes severe odors. These odors flow back out through the drainage holes of the manhole cover. You feel unpleasant.

Conventional representative manholes have a manhole frame and a plurality of drain holes formed on the inner circumferential surface of the manhole, and the drain holes are indispensable in the cover of the manhole, while the odors and mosquitoes inside the sewer in the drain hole are indispensable. Or cockroaches are leaking to the outside.

In particular, the problem of the conventional manhole as described above is a problem that must be solved in consideration of the increase in the purification effluent flowing into the sewer as the installation of a septic tank of a general household is mandatory, and moreover, in a crowded area such as a traditional market, As organic matter including food waste decayed in the sewers, the problem of odor leaking from manholes was more serious.

In consideration of these conventional problems, a device having a closing cover has been developed to allow rainwater and sewage to be discharged to the sewage normally and to automatically close by weight to prevent odors flowing out of the sewer.

However, since the installation structure of the closed cover and its associated structure is complicated, installation and replacement work are difficult, and thus workability is reduced and a separate weight is added, resulting in increased assembly labor and productivity, and due to the weight of the weight Because it is impossible to realize the sensitive center of gravity, there is a problem that the drainage effect is less because a small amount of drainage is not made well.

Accordingly, the present invention was devised to solve the above problems, by installing a main body having a fastening flange at the lower part of the manhole and a block plate that can be opened and closed automatically on the side of the main body to allow flow of water from the outside. It aims at being able to drain to a sewer smoothly, and to prevent the odor which arises from a sewer to discharge | release outside.

In order to achieve the above object, the present invention provides a manhole for blocking odor and backflow of sewage, which is installed at the lower part of the manhole, and has a flange at four upper sides and fastening holes for fastening with the manhole at each flange. It includes a main body provided with a hinge that can be rotated forward and is cut in the lower portion of the main body is installed to be opened and closed automatically and elastic means having elasticity by torsion springs located on both sides of the upper portion of the blocking plate. It features.

Another feature of the present invention is characterized in that the bottom surface of the main body is integrally molded with a water separator plate having an inclined surface of the '∧' shape for smoothly draining the flowing water to both sides.

Another feature of the present invention is characterized in that the rear surface of the main body is further provided with a hook for hanging a pesticide that can block odors and pests generated from sewage.

According to the above configuration and operation, the present invention is installed in the lower part of the manhole with a flange that can be fastened to the main body and the side of the main body can be automatically opened and closed to block the odor emitted from the inside of the sewer source, When the inflow can be automatically opened by the blocking plate can be smoothly drained not only to maintain a more pleasant road environment, but also easy to manufacture by simplifying the configuration can be manufactured at a low price manhole automatic opening and closing mechanism.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is an overall perspective view of a manhole automatic opening and closing mechanism according to the present invention, Figure 2 is a configuration view from above the manhole automatic opening and closing mechanism according to the present invention, Figure 3 is an embodiment of the manhole automatic opening and closing mechanism according to the present invention Figure 4 is a side view, according to the present invention is an embodiment of the hook is installed on the lower manhole automatic opening and closing mechanism according to the invention.

1 to 4, the present invention relates to a manhole for blocking odor and backflow of sewage. Manholes installed on roads or sidewalks to drain sewage or rainwater are blocks that are cured with concrete and have a plurality of rectangular, square, or straight drains.

The main body 10 of the present invention is a box-shaped open top and at least both sides are installed on the bottom of the manhole. The upper four surfaces of the main body 10 are provided with a flange 11 formed with a fastening hole 12 to be fastened and fixed with a manhole, and is configured to be coupled by fastening means such as bolts and nuts. All four side surfaces of the main body are inclined, and are molded to have a three-dimensional shape of an inverted pyramid (square pyramid) in the downward direction as a whole. The material of the main body 10 is preferably stainless steel or equivalent or more, which is advantageous for preventing corrosion, rather than mechanical strength.

Referring to FIG. 3, the present invention includes a blocking plate 20 that is normally blocked and automatically opens when sewage or rainwater is introduced from the outside to smoothly drain water. The blocking plate 20 is installed at open portions on opposite sides of the main body 10 to open and close the flow path. In order to couple to the open side of the main body 10, the hinge 22 is provided at both ends of the upper end in the longitudinal direction of the blocking plate 20 is fixed. The inner shaft of the hinge 22 has a central axis 23 that supports the weight of the blocking plate 20 and can assist the coupling of the main body 10. The central axis 23 is preferably an integral structure for simultaneously connecting the hinges 22 on both sides.

Accordingly, since the blocking plate 20 always blocks the bottom of the main body 10 when there is no inflow of rainwater or sewage, it prevents mosquitoes, fly flies, and other insects that live in the sewer from being transmitted out of the sewer. There is an advantage that can be prevented diseases, and provide a comfortable space environment.

In order to perform the automatic opening and closing operation of the blocking plate 20, an elastic means 21 having elasticity by a torsion spring is installed to surround the outer diameter of the central axis 23. The elastic means 21 normally acts to make the blocking plate 20 close to the bottom of the main body 10, but when sewage or rainwater flows from the outside, the elastic means 21 elastically deforms the hinge. The blocking plate 20 is rotated around the 22 and smoothly drained to the open side of the main body 10 by the amount of running water.

At this time, the torsion spring of the elastic means 21 may be appropriately set the elastic modulus in consideration of the amount of running water according to the installation area of the manhole. Of course, other members such as leaf springs may be used as the elastic means 21 in addition to the torsion springs.

As described above, the blocking plate 20 of the present invention blocks the main body 10 which is a passage to the outside when there is no inflow of sewage or rainwater, so that mosquitoes, fly flies and other insects inhabiting the sewer come out of the sewer. It can prevent diseases spreading from pests, provide a comfortable space environment, and prevent sewage flowing back from the sewer due to rainy season, and prevent damages caused by backflow in advance. Provide precautionary measures.

In addition, according to the present invention, the bottom surface of the main body 10 is formed in a '으로' shape is characterized in that it further comprises a water separator plate 13 of the form that rises in the upward direction.

Preferably, the water separator plate 13 is integrally formed on the bottom surface of the main body 10. Since the water separating plate 13 bisects the flowing water to drain to both sides, the water inside the main body 10 may be smoothly drained through the blocking plate 20, thereby preventing the water from sticking to the main body 10.

Another feature of the present invention is further provided with a hanger (30) to be installed on the bottom surface of the water separator plate constituting the bottom surface of the main body 10 to remove the odor and to exterminate pests It is configured to do so.

The present invention configured as described above is fixedly mounted on the bottom of the manhole installed on the side of the sidewalks or roads for people to block the odor emitted from the sewerage to provide a comfortable street space environment and sewage backflow that may occur due to rainy or heavy rain By blocking the phenomenon by the blocking plate, it provides the advantage of preventing the damage to the water in advance.
