Description
Technical field
The invention belongs to hydraulic engineerings to block dirty equipment technical field, be primarily adapted for use in the dirt of blocking of intake of hydropower station, specifically
It is related to a kind of swallow-tail form trash rack that grizzly bar folding is controlled by automatic device.
Background technique
It fetches water in water conveyance structure, trash rack is indispensable equipment.In pumping plant, power station and Shiplock Culvert
Trash rack is generally arranged in water inlet, to block the sundries (commonly referred to as dirt) such as the water plant of picked out band in water flow, drift wood, makes dirt
It is not easy to flow into penstock, to protect unit, gate, valve and pipeline without damage, guarantees the equipment such as unit, the safety fortune of structure
Row.Whether the arrangement of trash rack rationally directly influences the safe operation of building and trash rack itself, if arrangement is unreasonable
It will cause the very big inconvenience for losing economically and bringing operational management.When arrangement and design trash rack, it should utilize as much as possible
The advantages such as flow direction and landform avoid dirt into people's water inlet, as far as possible to mitigate the threat to trash rack；It is required that grid
Water flow is smooth, and head loss is small；In addition, being considered as removing contamination conveniently, it is easily installed, overhauls and replaces.
Trash rack includes grid leaf and grid slot embedded part two parts.Grid leaf is made of grid face and scaffold, and grid face is several piece
Grid connection arranges, and grid is formed by connecting by the metal grizzly bar put in parallel, and the mode of connection is bolted and welds
Two kinds.Bolted trash rack is detachable and replacement the trash rack of a kind of grid and grizzly bar, and grid is to use stay bolt
By the grizzly bar put in parallel through together.In order to keep grizzly bar spacing, equidistant spacer ring, stay bolt two are set between grizzly bar
End is screwed with nut.Grid is fixed on scaffold with u shape bolt.The trash rack of welded connecting is non-removable welding knot
Structure, grizzly bar and floor weld together composition grid, and the grizzly bar in grid is then directly welded on scaffold, forms grid
Face.But these conventional trash racks in normal work fix by grizzly bar, and the sundries contained by the upland water is too many, trash rack be unable to from
Dynamic folding, carries out self body adjustment, and dirt is caused to be attached to trash rack surface, so that dirt handling capacity is insufficient, causes to block
Dirty grid voltage difference frequency is numerous exceeded, frequency of removing contamination height.By the improvement to swallow-tail form grizzly bar, dirt blocks dirt by increasing before water inlet
The handling capacity of grid dirt.
Summary of the invention
For the problem for blocking dirty equipment dirt handling capacity difference at present, by changing to conventional dovetail grizzly bar trash rack
Into the present invention provides a kind of trash rack for controlling grizzly bar folding by automatic device.
The present invention solves scheme used by its technical problem: a kind of flexible swallow-tail form trash rack of linkage, including grid
Item and water passage, multiple groups grizzly bar are located at the frame mid portion of water passage side by side, and every group of grizzly bar includes the upper grizzly bar of activity and activity
Lower grizzly bar, the two can be swung by the way that central axle sleeve is hinged；Frame on the inside of water passage includes upper and lower two
Move in parallel bar, the upper end of the upper grizzly bar of activity and the lower end of the lower grizzly bar of activity, which are respectively hinged at, corresponding moves in parallel bar
On；The both ends for moving in parallel bar up and down have been respectively articulated with dynamic connecting rod, and the end of each dynamic connecting rod is separately installed with sliding axle；Meanwhile
Be fixedly installed on the two sides inner wall of water passage entrance be greater than outlet symmetrical convergence slideway, each sliding axle Matching installation in
In corresponding convergence slideway；It is set with interlocking bar in the central axle sleeve, is set with and pushes away at the middle part of interlocking bar or both ends
Pulling shaft set, push-and-pull axle sleeve are sequentially connected by attachment base with corresponding hydraulic cylinder.
Locating shaft has been uniformly arranged on bar in described move in parallel, the diameter of locating shaft is less than the diameter for moving in parallel bar,
Grizzly bar is set in the lower grizzly bar of activity in activity moves in parallel the corresponding locating shaft of bar.
Grizzly bar and grizzly bar under activity in activity can be made automatic being equipped between grizzly bar under the upper grizzly bar of each activity and activity
The torsional spring of expansion.
The beneficial effects of the present invention are: big dirt will receive trash rack when dirt passes through trash rack from water inlet
It stops and can not pass through, the present apparatus is by sliding of the automatic device control-rod in slideway, to control opening for swallow-tail form grizzly bar
It closes, increases the handling capacity of trash rack dirt.

Specific embodiment
As depicted in figs. 1 and 2, the multiple groups grizzly bar of the flexible swallow-tail form trash rack of linkage is located at the frame of water passage side by side
Middle part.As shown in figure 3, every group of grizzly bar includes the upper grizzly bar 2 of activity and the lower grizzly bar 3 of activity, the two is hinged on one by central axle sleeve 5
Rising can swing.
Fig. 1 and Fig. 2 shows frame structure relationship, and the frame on the inside of water passage includes upper and lower two and moves in parallel
Bar 1.The upper end of grizzly bar 2 and the lower end of the lower grizzly bar 3 of activity are respectively hinged at corresponding move in parallel on bar 1 in activity.Specifically,
Locating shaft 4 is uniformly arranged on moving in parallel bar 1, the diameter of locating shaft 4 is less than the diameter for moving in parallel bar 1, grid in activity
Item and the lower grizzly bar 3 of activity are set in and move in parallel the corresponding locating shaft 4 of bar 1.
The both ends for moving in parallel bar 1 up and down have been respectively articulated with dynamic connecting rod 7, and the middle part of dynamic connecting rod 7 is equipped with sliding axle 8, sliding
Moving axis 8 can on dynamic connecting rod 7 Slideslip.Meanwhile the end of each dynamic connecting rod 7 is separately installed with sliding axle 8.The two of water passage
The symmetrical convergence slideway 6 that entrance is greater than outlet is fixedly installed on the inner wall of side, each 8 Matching installation of sliding axle is slided in corresponding convergence
In road 6.
It is set with interlocking bar 9 in the central axle sleeve again, is set with push-pull shaft at the middle part of interlocking bar 9 or both ends
Set, push-and-pull axle sleeve are sequentially connected by attachment base with corresponding hydraulic cylinder.Interlocking bar 9 can be rotated relative to central axle sleeve, and
And spaced block machine is set for constraining each central axle sleeve in 9 side wall of interlocking bar.
When dirt passes through trash rack from water inlet, the trash rack controlled by automatic device starts first when implementing
Automatic device, then bar is slided in slideway by control, so that chain bar and grizzly bar are gradually closed, so that dirt handling capacity increases
Greatly.
Embodiment 2: it is being equipped with and can make between grizzly bar 3 under the upper grizzly bar 2 of each activity and activity again on that basis of example 1
The torsional spring of grizzly bar 2 and lower 3 Automatic-expanding of grizzly bar of activity in activity.Under natural conditions, the activity of each group grizzly bar under the effect of torsion spring
Upper grizzly bar 2 and the lower grizzly bar 3 of activity are all in unfolded state, in the case where needing to change water amount, again by driving traction wheel
13 contractile motion of two sides wirerope is driven, so that driving moves in parallel bar 1 up and down carries out contractile motion, at this time by moving in parallel up and down
Lever 1 drives grizzly bar 2 and the lower grizzly bar 3 of activity in the activity of each group grizzly bar to carry out contractile motion, realizes the purpose of control displacement.
