Description

Inverter construction frame of a manhole}

The present invention relates to an inverter structure of the manhole, the invention relates to an inverter structure of the manhole that can easily discharge the sewage and sediment by simply matching the inlet pipe connected to the manhole at various angles with the inlet inside the manhole.

Generally, the invert is a bottom structure of a manhole that serves to prevent odors and the like by allowing sewage and sediment flowing into the manhole to be smoothly discharged without being deposited.

This prior art is a registered utility model No. 20-298666 "manhole", which is to make a predetermined inclination angle of the bottom surface 11 of the manhole 10 from the inlet 12 side to the drain port 13 side, the The bottom surface 11 is formed by forming a sewage guide groove 14 that becomes a semicircular shape at a predetermined position on the inclined bottom surface 11 to guide the sewage flowing into the drain port 13 side.

Therefore, the inlet 12 corresponding to the position corresponding to the inlet line 20 of the inlet line 20 is positioned after the drain hole 13 of the manhole 10 is disposed toward the outlet line 30. ), The inlet pipe 20 and the outlet pipe 30 are easily connected.

However, in the inverter structure of the conventional manhole 10 as described above, since the direction of the inlet pipe 20 is not constant, it does not exactly match the direction of the inlet 12, and in this case, the installation is It is difficult and hassle to use a separate member such as elbow.

The present invention improves the structure of the inverter of the conventional manhole as described above, and even if the direction of the inlet pipe is connected in any direction, the inlet and the drain port of the inverter is correctly connected to the inlet pipe and the discharge pipe to facilitate the discharge of sewage. There is an object of the invention.

Therefore, the configuration of the present invention for achieving the above object is made of a cylindrical of a predetermined diameter in the manhole for draining sewage, a drainage is formed on one upper surface and the sewage guide groove is spoken from the drainage to the center, the other side The bottom plate is provided with a guide sphere of a predetermined width that is curved by a predetermined angle at a predetermined radius; One side is cut by a predetermined angle to form a fan-like shape, at least one semicircular sewage guide groove is formed radially on the upper surface, the bottom surface to be rotatable by a predetermined radius in a form that is in contact with the guide sphere of the bottom plate. It is characterized by consisting of; a rotating plate provided with a guide sphere to be coupled.

In addition, the configuration of the present invention is characterized in that the bottom plate is made to be separated from the manhole, the top surface of the bottom plate is characterized in that it is made slightly inclined toward the drain port side.

Hereinafter, the present invention will be described with reference to the accompanying drawings in order to explain in more detail as follows.

Figure 3 is an exploded perspective view showing the inverter structure of the manhole according to the invention, Figure 4 is a partial perspective view of a state in which the inverter structure of the manhole according to the present invention is coupled.

Inverter structure of the present invention to form a sewage guide groove 41 and the drain hole 42 on the upper surface of the cylindrical manhole 10 bottom plate 40 of a predetermined diameter, the sewage guide groove 41 is a bottom plate ( 40 is formed to be recessed to the center of the bottom plate 40 in a semi-circular shape from the drain port 42 formed on one side, the upper surface of the bottom plate 40 is formed to be somewhat inclined toward the drain port 42 side sewage And to facilitate the drainage of dirt.

In addition, a guide sphere 43 is formed on the other upper surface of the bottom plate 40, and the guide sphere 43 protrudes by drawing a circle by a predetermined angle at a predetermined width and height, or a predetermined angle at a predetermined width and depth. It is also preferable to form a depression by drawing a circle.

At this time, the bottom plate 40 may be integrally formed on the bottom of the manhole 10, but is provided separately, it is also preferable to use after mounting on the bottom of the conventional manhole 10.

And, the upper side of the bottom plate 40 is provided with a separate rotating plate 50, the rotating plate 50 is one side is cut in a predetermined angle is formed in a fan shape, the upper surface of the sewage in the form of a semi-circular Guide groove 51 is formed from the center to the outer inlet (52). At this time, the sewage guide groove 51 and the inlet 52 is formed radially at least one (three in the drawing), so that it can be applied to the inlet pipe 20 connected in various directions.

In addition, the bottom surface of the rotating plate 50 to form a guide sphere 53 in the form that is in contact with the guide sphere 43 of the bottom plate 40, the guide sphere 43 of the bottom plate 40 When protruding, the recess is formed, and when the guide sphere 43 of the bottom plate 40 is recessed, it protrudes. On the other hand, by forming a smaller circumferential length of the guide sphere side protruding and inserted than the guide sphere side of the guide sphere 43, 53, it is possible to rotate the rotating plate 50 by the difference length.

In the above description, reference numeral 60 denotes a pipe fastener, 61 denotes a guide plate formed on the pipe fastener, and 62 denotes a socket.

Therefore, when the bottom plate 40 is integrally formed in the lower part of the manhole 10 in order to install the manhole 10, it may be installed as it is, but when the bottom plate 40 is provided separately, the manhole 10 After placing the bottom plate 40 on the bottom of the drain plate 42 formed in the bottom plate 40 is positioned to the discharge pipe passage 30 side of the sewage.

Then, the rotating plate 50 is rotated in one direction so that the inlet pipe 20 side and the inlet port 52 side of the rotating plate 50 coincide with each other. Then, the rotating plate 50 is coupled to the guide hole 43 of the bottom plate 40 by the guide port 53 and rotates at a predetermined radius, and one inlet port 52 of the inlet port 52 is the inlet pipe ( If the direction coincides with the direction of 20), it stops, and a through hole 15 is formed in the side wall of the manhole 10 at the corresponding point, and the inlet pipe 20 is coupled using a separate pipe fastener 60 or the like. .

At this time, since the plurality of inlets 52 are formed at predetermined angles, when the rotating plate 50 is rotated only by a predetermined angle in a direction close to the direction of the inlet pipe 20 to be connected, the inlet pipe 20 and the inlet port ( 52 can be easily matched, so that the inlet pipe 20 connected in almost all directions can be easily matched with the inlet port 52 for connection.

On the other hand, the pipe fastener 60 by using the utility model registration application No. 20-2003-0034527 "piping fastener" filed by the applicant, the fastening operation of the inlet pipe 20 is easy and firmly fastened It is possible to introduce the sewage into the sewage guide groove 51 by the guide plate 61 to facilitate drainage.

Therefore, the sewage and the dirt flowing through the inflow pipe 20 flows to the center side of the rotating plate 50 through the sewage guide groove 51 formed to be inclined, and after reaching the center side, the bottom plate 40 below. Take the sewage guide groove (41) formed in the drain back to the drain 42 and flows through the discharge pipe (30).

As described above, the present invention has been described in detail according to an embodiment, but the present invention is not limited thereto. In particular, the manhole includes one embodiment, in which a branch pipe is connected in various directions in a similar manner. Applicable to

Therefore, it is a matter of course that changes and modifications made within the scope of the present invention as described above are also included in the concept of the present invention.

The present invention can easily match the inlet portion of the pipe and the inside of the manhole connected in various directions outside the manhole, it is not necessary to use an auxiliary member, such as elbow, manhole construction is easy, work time is reduced and inflow sewage And useful inventions in which dirt can be discharged smoothly without being deposited.
