Abstract
The utility model relates to a folding multi-hinged-steel gate. The utility model is an improvement for a bottom pour type five transverse axis automatic switching gate which is used in a mountain area power station and the hinge support of which is easily blocked by tree branches and sundries and can not normally work. The utility model is characterized in that a flashboard composed of a plurality of hinged gate leaves (4), gate leave hinges are provided with limiting blocks (2) and limiting pulling ropes (3) which are connected to the limiting blocks and can adjust the gate height; when the gate normally works, a cable (1) is lifted to cause the hinged gate leaves (4) to form sawtooth shape and get a favorable stress state; when the gate drains and discharges sundries, definite length of the lifted cable (1) is let down, the gate leaves (4) are folded, and the redundant water and floating sundries are discharged from the gate top.
Description
The utility model relates to a kind of improved dam gate, particularly a kind of collapsible many hinge steel gates.Be applicable to the power station, mountain area.
At present, the pocket floor drainage type five transverse axis automatic switch gates that use in the dam of existing power station, this gate can be regulated discharge opening degree of liter according to water level height automatic switch on the gate.Because most of power station is located in the mountain area, collective area is big, the annual wet season (the 2--9 month), the branch foreign material that drifting about a large amount of in the riverbed, when water level is higher than ordinary water level on the dam, five transverse axis gates are opened sluicing automatically, floating branch foreign material are also let out under the pocket floor with current, the branch foreign material are easy to block and hang on movable hinged and the flashboard like this, this not only influences normal earial drainage, and when water level reduces, and is hingedly blocked by the deadwood foreign material, gate can not be closed water storage automatically, causes a large amount of loss wastes, head loss.Need spend also simultaneously that water opens the port-cullis door under a large amount of manpowers, foreign material are blocked in cleaning.
The purpose of this utility model is the defective that exists at underflow gate, proposes a kind of small investment, produces simply, can conveniently sluice and discharge the collapsible many hinge steel gates of lock top overflow of floating branch foreign material.
Collapsible many hinge steel gates are characterised in that flashboard is by hinged the forming of the folding gate flap of polylith, actual needs according to water storage, sluicing, change folding amount and can adjust total elevation of gate flap group, each gate flap hinge and the fixing hinge of lock trench bottom that are positioned at the motion of lock groove direction are equipped with the limited block that connects for spacing stay cord, when this spacing steel wire tow line guarantees that gate promotes, above several unlikely being straightened of gate flap, keep between gate flap certain included angle being arranged, make gate flap be in good stress.Can change the spacing steel wire tow line length between limited block according to actual needs, change gate control water level elevation.During flood discharge, progressively put down gate and promote hawser, each gate flap is folded up under the deadweight effect, and flood and branch foreign material just can be drained on the lock top smoothly.
The utility model is compared with existing underflow gate and is had the following advantages:
1. the draining of lock top makes the wet season drain floating foreign material in the river course better, has alleviated floating thing widely to the obstruction of power station water inlet with manually drag for the labour intensity of impurities removal thing.
2. owing to reduced the obstruction of floating thing, and can artificially control upstream water level and sluicing time and bleeder quantity to the power station water inlet, thus can improve greatly water can utilization rate.
3. collapsible many hinge steel gates described in the utility model are stressed good, and the bending resistant section square is big, uses steel to reduce relatively on weight, adds that gate flap is to bear water pressure piecewise when opening and closing, so hoisting capacity is littler than the gate of other pattern.
4. but collapsible many hinge steel gate bursts described in the utility model are made, the burst assembling, make, transportation, install simple and convenient, wide adaptability.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model complete shut-down position view.
Fig. 2 is the utility model part enable possition schematic diagram.
Fig. 3 is the utility model fully open position schematic diagram.
Fig. 4 is the utility model superelevation position view.
Fig. 5 is the drawing of A moveable hinge among Fig. 1.
Fig. 6 is the drawing of B moveable hinge among Fig. 1.
Referring to Fig. 1, collapsible many hinge steel gates, by the polylith gate flap 4. (Fig. 1 is four gate flaves) be hinged together with moveable hinge A and the hinged moveable hinge B that is centered close to the motion of lock groove direction, topmost gate flap upper end and the interior activity of lock groove wheel shaft of propping up hinge wheel 4. is hinged.The most beneath gate flap lower end 4. is hinged on the fixing hinge wheel wheel shaft.In the hinged drawing of A and B.Two gate flaves 4. respectively connect the connection hinge 5. length 1/2nd connection hinge turning set 6., 4. utilize the connection hinge 5. to be inserted in connection hinge turning set is hinged together two gate flaves in 6., 7. hinged upstream face is connected two gate flaves with the water stop rubber piece and 4. goes up, because water stop rubber has better elastic and sealing performance, gate flap can be relatively rotated between 4. and be unlikely and leak.Each gate flap side 4. also is equipped with the water stop rubber piece, makes gate flap 4. can prevent from effectively to leak during motion on the water stop rubber piece of side on the gate pier wall, and river has only full lockage to push up just to release like this.
When collapsible many hinge steel gates were worked, the gate hoist structure imposed on 4. lifting force of gate flap, and 4. this power rise to the ordinary water level height with hinged multi-door leaf, and 1. locking promote hawser then, promptly obtains the complete shut-down position (see figure 1) of operate as normal.In lifting process, promptly reduce to make up the bending resistant section square of gate flap in order to prevent that 4. top gate flap is straightened, can multi-door leaf 4. the back side of gate move along lock groove direction hinged on limited block is installed 2., thereby 2. each limited block connects a spacing steel wire splicing 4. top several gate flaves are not straightened.Before surpassing ordinary water level or lock, blocks the riverbed water level when having blocked up many branch foreign material and need get rid of, 1. the lifting hawser of gate is put down certain-length, gate flap is 4. under the deadweight effect, folding from bottom to top, form part enable possition (see figure 2), water and swim in branch foreign material waterborne and excrete out along the lock top.In flood when outburst, for counter dam drains off floodwaters, reduce the upstream damage from a flood, then should all put down promoting hawser 1., makes each gate flap 4. folding fully, and gate is reduced to the 4. summation height of thickness of each gate flap, with the fully open position (see figure 3) of drainning off floodwaters.The above farmland of reservoir area ordinary water level in dry season just in time is the phase of lying fallow, can be according to actual conditions, regulate spacing wire rope 3. the length of each limited block between 2., improve gate control water level elevation (being Fig. 4 superelevation position) to increase spacing length, improve the reservoir area head, multiple.
