Description
Technical Field
The invention relates to a bulb-type dirt blocking structure of a drain pipeline, and belongs to the technical field of metal structures of hydraulic and hydroelectric engineering.
Background
Based on environmental protection needs, the water conservancy and hydropower engineering is generally provided with a drain pipe at the bottom for discharging ecological flow, and the drain pipe is generally operated by adopting a drain valve because of a small orifice size and a high operation water head. Considering that the bottom suspended load or the bed load of the sewer pipeline enters the runner to possibly damage the valve body, a fixed trash rack is generally arranged at the inlet of the sewer pipeline. The traditional fixed trash rack adopts a welding structure, and because the grid plates are fixed only by welding seams at the contact parts of the grid plates and the trash rack frame, the trash rack is used in a sewer pipe with overhigh flow velocity, the grid plates are easy to break, larger dirt is caused to enter the sewer pipe to damage a valve body, and the trash rack is only suitable for occasions with low flow velocity, so the prior art is still imperfect and needs to be further improved.
Disclosure of Invention
The invention aims to provide a bulb-type sewage blocking structure of a sewer pipe, which is used for preventing a grid plate from being broken due to high flow speed in the sewer pipe, so that larger sewage enters the sewer pipe to cause damage to a valve body, and further overcomes the defects in the prior art.
In order to achieve the above purpose, the invention adopts the following technical scheme:
the invention relates to a bulb-type sewage blocking structure of a sewage pipeline, which comprises the sewage pipeline; a reducing pipe protruding out of the vertical face of the dam body is arranged at the water inlet of the drain pipeline; an annular steel plate is arranged at the joint of the dam body elevation and the reducing pipe, and reinforcing ribs which are uniformly distributed along the circumference are arranged between the outer side of the annular steel plate and the reducing pipe; a bulb-type dirt blocking cover is arranged at the water inlet of the reducing pipe; the bulb type dirt blocking cover is connected with the reducing pipe through a flange.
In the structure, the bulb-type dirt blocking cover comprises a spherical shell section and a circular tube section, and the spherical shell section is in arc transition connection with the circular tube section; the other end of the circular tube section is connected with the reducing tube.
In the structure, a group of round holes are uniformly distributed on the spherical shell section of the bulb-type dirt blocking cover.
In the structure, the round holes comprise central holes, and the rest round holes are distributed around the central holes in a layering manner along the circumference.
In the structure, round holes between layers are rotated by a certain angle to be staggered to form a plum blossom shape.
In the above structure, the center lines of all the round holes meet at the center of the spherical shell.
Due to the adoption of the technical scheme, compared with the prior art, the dirt blocking cover is a bulb-shaped shell with circular holes uniformly arranged in an annular mode, the whole stress of the shell is uniform, the manufacture is simple, the stress concentration caused by welding is avoided, the material is saved, dirt is not easy to adhere to the dirt blocking cover, and dirt blocking is facilitated; in addition, when water flows enter the drain pipeline through the round holes, the water flows collide with each other to dissipate energy, so that the flow speed of the drain pipeline is reduced, the vibration of the dirt blocking cover during overflow is reduced, and the running water head of the drain valve is effectively improved.
