Description
Technical field
The present invention relates to a kind of sluice pipe bulb types to block dirty structure, belongs to hydraulic and hydroelectric engineering metal structure technical field.
Background technique
It being needed based on environmental protection, usually sluice pipe will be arranged for ecological flow of releasing in bottom in hydraulic and hydroelectric engineering, and
Sluice pipe is higher general using drain valve operation because of the smaller operating head polishing of port size.Consider sluice pipe bottom suspended load or
Bed load enters runner and is likely to result in valve body damage, and fixed trash rack is generally arranged in its import.It is traditional fixed to block
Dirty grid use welding structure, only lean on because of grid and fix with the weld seam of fence frame contact site, in the tapping pipe that flow velocity is excessively high
It being used in road, grid easily snaps off, and it causes larger dirt to enter sluice pipe damage valve body, is only suitable for the conjunction of flow velocity low field,
So the prior art or incomplete, needs to be further improved.
Summary of the invention
The purpose of the present invention is to provide a kind of sluice pipe bulb types to block dirty structure, to prevent flow velocity mistake in stopping leak waterpipe
Height makes grid fracture, and causes larger dirt to enter sluice pipe, valve body is caused to damage, thus overcome the deficiencies in the prior art.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of sluice pipe bulb type of the invention blocks dirty structure, including sluice pipe；It is equipped with and protrudes in sluice pipe water inlet
The reduced pipe of dam body facade；Cyclic annular steel plate, cyclic annular steel plate outside and reduced pipe are equipped in the junction of dam body facade and reduced pipe
Between be equipped with the ribs that is uniformly distributed along the circumference；The water inlet of reduced pipe is equipped with bulb type dirt barrier hood；Bulb type dirt barrier hood and reducing
Through flanged joint between pipe.
In aforementioned structure, the bulb type dirt barrier hood includes spherical shell section and round tube section, circular arc between spherical shell section and round tube section
Transition connection；The round tube section other end is connect with reduced pipe.
In aforementioned structure, one group of circular hole is evenly equipped in the spherical shell section of the bulb type dirt barrier hood.
In aforementioned structure, the circular hole includes centre bore, remaining circular hole is layered around centre bore and is uniformly distributed along the circumference.
In aforementioned structure, circular hole between layers, which rotates by a certain angle, is staggered into plum blossom-shaped.
In aforementioned structure, round-meshed center line cross at the centre of sphere of spherical shell.
By adopting the above-described technical solution, compared with prior art, the present invention dirt barrier hood of the present invention is that ring-type is uniformly set
Set the bulb type shell of circular hole, shell entirety uniform force is simple to manufacture, stress caused by welding concentrate, material relatively save and
Dirt is not easy to be attached in dirt barrier hood, is conducive to block dirt；Disappear in addition, water flow can be collided mutually when entering sluice pipe by circular hole
Sluice pipe flow velocity can be advantageously reduced, mitigates vibration when dirt barrier hood overcurrent, effectively increases the operating head polishing of drain valve.

Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.
A kind of sluice pipe bulb type of the invention blocks dirty structure, as shown in Figure 1, including sluice pipe 1；Its feature exists
In: the reduced pipe 3 of prominent dam body facade 2 is equipped in 1 water inlet of sluice pipe；It is set in dam body facade 2 and the junction of reduced pipe 3
There is cyclic annular steel plate 4, is equipped with the ribs 5 being uniformly distributed along the circumference between cyclic annular 4 outside of steel plate and reduced pipe 3；The water inlet of reduced pipe 3
Equipped with bulb type dirt barrier hood 6；It is connected between bulb type dirt barrier hood 6 and reduced pipe 3 through flange 7.As shown in Fig. 2, bulb type blocks dirt
Cover 6 is connect including 11 transition of circular arc between 9 sections and 10 sections of round tube, 9 sections and 10 sections of round tube of spherical shell of spherical shell；10 sections of other ends of round tube with
Reduced pipe 3 connects.One group of circular hole 8 is evenly equipped on 9 sections of spherical shell of bulb type dirt barrier hood 6.Circular hole 8 includes centre bore 12, remaining
Circular hole 8 is layered around centre bore 12 and is uniformly distributed along the circumference.Circular hole 8 between layers, which rotates by a certain angle, is staggered into plum blossom
Shape.The center line 13 of all circular holes 8 crosses at the centre of sphere 14 of spherical shell 9.
Embodiment
The sluice pipe bulb type of this example blocks dirty structure, as shown in Figure 1, it is vertical that prominent dam body is arranged in 1 import of sluice pipe
Cyclic annular steel plate 4 is arranged in the reduced pipe 3 in face 2, dam body facade 2 and 3 junction of reduced pipe.It is arranged on cyclic annular steel plate 4 cyclic annular uniform
The ribs 5 of arrangement is welded with reduced pipe 3；In 3 front end of reduced pipe, bulb type dirt barrier hood 6 is set；Bulb type dirt barrier hood 6 and reducing
