Description
Technical field
The present invention relates to pumping plant blocks dirt, field of removing contamination and in particular to a kind of water conservancy system bends font trash rack.
Background technology
Before pumping plant, setting trash rack can stop dirt（Mainly pasture and water）Enter water pump it is ensured that water pump assembly runs peace
Entirely.Trash rack typically adopts planar shaped, becomes 75 ° or 90 ° to be placed in diversion channel or pumping plant intake pool with the water surface（Feed water flow
Road）Before.Large pumping station need to arrange service bridge of removing contamination, and is equipped with trash.Small and medium-sized pumping station does not typically set dirt cleaner, needs manually clear
Dirt, difficulty of removing contamination, danger, workload of removing contamination is big.For various lots of rural area small and medium-sized pumping station, before grid, dirt with pasture and water is
Main, pasture and water proportion is less than water body, and the pasture and water bubbled through the water column block top grid face first, if top grid face pasture and water are clear not in time
Remove, in the case that flow velocity is larger, follow-up pasture and water are easily dived beneath the water with current and block middle part and bottom grid face, block sewage head and damage
Mistake is increased dramatically to 0.3～1.0m, and cause manually to remove contamination difficulty, and pump installation lift increases, and flow reduces, countershaft stream
Pump and higher specific speed mixed-flow pump, pump shaft power increases, and efficiency of pumping station reduces.Pumping plant suction inlet water level decreasing mistake after trash rack grid
When many, also can cause pump cavitation, when serious, cause grid body to collapse.Pumping plant blocks dirt, if dirt is removed not in time before grid, can make
Become operating cost to be significantly increased, affect the safe and stable operation of water pump assembly.Therefore, small and medium-sized pumping station needs one kind to block dirty resistance
Little, be easy to the trash rack manually removed contamination.
Content of the invention
It is an object of the invention to provide a kind of water conservancy system bends font trash rack, upper with solve to lead in prior art
State multinomial defect.
A kind of water conservancy system bends font trash rack, including side bar, left vertical beam, right vertical beam, central sill and grizzly bar, described left vertical beam
On the left of central sill, on the right side of central sill, described side bar connects respectively described right vertical beam located at the both sides up and down of central sill, described side bar
Connect left vertical beam and right vertical beam, described grizzly bar is uniformly distributed between side bar, left vertical beam and right vertical beam.
Preferably, it is provided with rotary shaft in described central sill, rotary shaft two ends are provided with nut, and central sill is rotated by rotary shaft.
Preferably, fixed by mounting pin and fastening chock between described side bar and left vertical beam, right vertical beam.
Preferably, it is connected with gag lever post between described left vertical beam and right vertical beam.
Preferably, described side bar is provided with adjustment tooth bar, and right vertical beam is provided with adjustment projection, and adjustment tooth bar is raised with adjustment
Cooperate.
It is an advantage of the current invention that：The present invention is arranged by left and right beam, forms bow font trash rack, bends font shape trash rack
Grid face area is big compared with planar shaped trash rack, when before the pasture and water blocking grid of same volume, bends the unplugged excessively stream of font shape trash rack
Area is larger, and it is less to block sewage potential difference, using bow font shape trash rack, grid body large carrying capacity, can save service bridge of removing contamination,
Reduce engineering cost, reduce pumping plant main frame operating cost, clean-up cost can be reduced again and use and workload, applied widely, practicality
By force.
Brief description
Fig. 1 is the front view that a kind of water conservancy system of the present invention bends font trash rack.
Fig. 2 is the attached view that a kind of water conservancy system of the present invention bends font trash rack.
Fig. 3 is the sectional view at I-I in Fig. 1.
Wherein：1 side bar, 2 left vertical beams, 3 right vertical beams, 4 rotary shafts, 5 gag lever posts, 6 central sills, 7 grizzly bars.
Specific embodiment
Technological means, creation characteristic, reached purpose and effect for making the present invention realize are easy to understand, with reference to
Specific embodiment, is expanded on further the present invention.
As depicted in figs. 1 and 2, a kind of water conservancy system bends font trash rack, including side bar 1, left vertical beam 2, right vertical beam 3, in
Beam 6 and grizzly bar 7, described left vertical beam 2 on the left of central sill 6, described right vertical beam 3 on the right side of central sill 6, described side bar 1 located in
The both sides up and down of beam 6, described side bar 1 connects left vertical beam 2 and right vertical beam 3 respectively, and described grizzly bar 7 is on side bar 1, left vertical beam 2 and the right side
It is uniformly distributed between vertical beam 3.
It should be noted that being provided with rotary shaft 4 in described central sill 6, rotary shaft 4 two ends are provided with nut 41, during rotary shaft makes
Beam 6 rotates more quick.
In the present embodiment, pass through mounting pin 21 between described side bar 1 and left vertical beam 2, right vertical beam 3 and fastening chock 22 is solid
Fixed, mounting pin 21 makes side bar 1 and the connection of left vertical beam, right vertical beam 3 more fasten with fastening chock 22.
Additionally, being provided with gag lever post 5 between described left vertical beam 2 and right vertical beam 3, the structure of bow font trash rack is made to keep steady
Fixed, enhance the ability of opposing current.
Additionally, described side bar 1 is provided with adjustment tooth bar 11, right vertical beam 3 is provided with adjustment raised 12, adjusts tooth bar 11 and adjusts
Whole raised 12 cooperate.
Based on above-mentioned, the present invention is arranged by left and right beam, forms bow font trash rack, bow font shape trash rack grid face area
Big compared with planar shaped trash rack, when before the pasture and water blocking grid of same volume, the bow unplugged area of passage of font shape trash rack is larger,
Block sewage potential difference less, using bow font shape trash rack, grid body large carrying capacity, service bridge of removing contamination can be saved, reduce engineering
Expense, reduces pumping plant main frame operating cost, can reduce clean-up cost again and use and workload, applied widely, practical.
As known by the technical knowledge, the present invention can be by the embodiment party of other essence without departing from its spirit or essential feature
Case is realizing.Therefore, embodiment disclosed above, for each side, is all merely illustrative, and is not only.Institute
Have within the scope of the present invention or be all included in the invention in the change being equal in the scope of the present invention.
