Description
Technical field
This utility model relates to power station and removes contamination field, is specifically related to a kind of modified model trash rack.
Background technology
Xi He hydraulic power plant annual flood season, a large amount of float and floating thing that flood brings are jammed before unit trash rack, drastically influence the normal power generation of unit and the operation safety of trash rack.In order to effectively solve the unit water inlet touting problems in flood season, a set of mechanization sewage disposal apparatus is installed in December, 2014 by Xi He hydraulic power plant, dirt before trash rack can be cleared up under unit open state by this device, neither affect the normal power generation of unit, can ensure that again trash rack runs safety.
In April, 2015, this trash puts into operation and finds when using, trash grab bucket is left the water in the moving process of trash rack top grabbing full dirt, owing to rocking or part dirt is stopped by trash rack grizzly bar, dirt falls to trash rack top and the downstream water surface (trash rack downstream is away from trash rack groove metope 1000 millimeters) thereof, flows into unit spiral case with current.Dirt as bigger in tree root, trunk etc. enters inside unit spiral case; machine set water guiding leaf can be caused to clamp these bigger dirts during adjusting aperture; guide vane is made can not normally to adjust or close; guide vane break pin is caused to be cut off; unit is not normally functioning and orderly closedown; and trash rack can only overall use, it is impossible to dismounting, part is difficult to when being damaged change.
Summary of the invention
The purpose of this utility model is to provide a kind of modified model trash rack, to solve the above-mentioned multinomial defect caused in prior art.
A kind of modified model trash rack, including grid body framework, crossbeam and grid body sheet, described grid body sheet is made up of grizzly bar connecting plate and grizzly bar, grizzly bar is welded on grizzly bar connecting plate, described crossbeam is I-shaped structure, grid body sheet bolt is fixedly installed on crossbeam, described grid body framework is left, the right side is respectively provided on two sides with left chute and right rail, left slider and right slide block it is respectively equipped with in left chute and right rail, crossbeam side is connected with left slider, opposite side is connected with right slide block, described grid body frame upper surface is also fixedly connected with inclination grizzly bar, angle between described inclination grizzly bar and grid body framework is 120 °-150 °.
Preferably, after described grid body framework uses rustless steel or the welding of ordinary steel tubing, painting corrosion resistant coating is made.
Preferably, in described left chute and right rail, opposite position is equipped with on draw-in groove, described left slider and right slide block and is equipped with card key, draw-in groove and the mating shapes of card key.
Preferably, between described inclination grizzly bar, connection has reinforcement.
Preferably, described grizzly bar is bar shaped band steel, and upstream face is provided with rounding.
The utility model has the advantage of: this kind of modified model trash rack, can be according to actual practical needs by crossbeam be adjusted by the regulation of left slider and right slide block, thus band moving grid body sheet carries out the adjustment on position, so the impurity of different buoyancy it is applicable to, tilt grizzly bar can the dirt that drop during trash crawl be intercepted, thus avoid it to enter electromotor unit spiral case, impact uses.

Wherein: 1-reinforcement, 2-tilts grizzly bar, 3-grid body framework, 4-left slider, 5-crossbeam, 6-grid body sheet, 7-grizzly bar connecting plate, 8-grizzly bar, the right slide block of 9-.
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with detailed description of the invention, this utility model is expanded on further.
nullAs Figure 1-Figure 4，A kind of modified model trash rack，Including grid body framework 3、Crossbeam 5 and grid body sheet 6，Described grid body sheet 6 is made up of grizzly bar connecting plate 7 and grizzly bar 8，Grizzly bar 8 is welded on grizzly bar 8 connecting plate 7，Can assemble by burst，Dismantle more convenient，Described crossbeam 5 is I-shaped structure，Enhance impact resistance，Grid body sheet 6 bolt is fixedly installed on crossbeam 5，Described grid body framework 3 is left、The right side is respectively provided on two sides with left chute and right rail，Left slider 4 and right slide block 9 it is respectively equipped with in left chute and right rail，Crossbeam 5 side is connected with left slider 4，Opposite side is connected with right slide block 9，Described grid body framework 3 upper surface is also fixedly connected with inclination grizzly bar 2，Angle between described inclination grizzly bar 2 and grid body framework 3 is 120 °-150 °，The dirt that can drop during capturing trash intercepts，Thus avoid it to enter electromotor unit spiral case，Impact uses.
It should be noted that, described grid body framework 3 is coated with corrosion resistant coating after using rustless steel or the welding of ordinary steel tubing and makes, antiseptic property and good stability, and low cost, in described left chute and right rail, opposite position is equipped with draw-in groove, and described left slider 4 and right slide block 9 are equipped with the mating shapes of card key, draw-in groove and card key, after crossbeam 5 being adjusted to certain position by adjustment left slider 4 and right slide block 9, left slider 4 and right slide block 9 are fixed by available card key.
At the present embodiment, connect between described inclination grizzly bar 2 and have reinforcement 1, described grizzly bar 8 is bar shaped band steel, upstream face is provided with rounding, reduce resistance to water-flow, described grid body framework 3 is provided with many crossbeams 5 and organizes slide block more, the most every two one group, grid body sheet 6 it has been bolted between two crossbeams 5, can be according to the dirt buoyancy adjustment slide block in concrete current, thus the position of grid body sheet 6 is adjusted, if dirt buoyancy is more uniformly and dirt is more in water, can be according to using the quantity needing to increase crossbeam 5.
Based on above-mentioned, this kind of modified model trash rack, can be according to actual practical needs by crossbeam 5 be adjusted by the regulation of left slider 4 and right slide block 9, thus band moving grid body sheet 6 carries out the adjustment on position, so the impurity of different buoyancy it is applicable to, tilt grizzly bar 2 can the dirt that drop during trash crawl be intercepted, thus avoid it to enter electromotor unit spiral case, impact uses, this utility model provides a kind of dirt that can drop during capturing trash and intercepts, and Stability Analysis of Structures, modified model trash rack applied widely.
As known by the technical knowledge, this utility model can be realized by the embodiment of other essence without departing from its spirit or essential feature.Therefore, embodiment disclosed above, for each side, all it is merely illustrative, is not only.All all it is included in the utility model in the range of this utility model or being equal to the change in the range of this utility model.
