Description
Technical field
A kind of present specification movable dam support system technical field, and in particular to movable dam support bar manual release device.
Background technology
Movable dam is the scientific and technological achievement that water conservancy is administered, and is movable dam technology leading in current check dam, and it is extensive
For projects such as agricultural irrigation, fishery, ship lock, middle and small river improvement, hydroelectric generation, urban water system and tourist sights.
Support bar plays firm supporting role to movable dam facing, when fell movable dam flood discharge when, need first support hydraulic pressure
Cylinder extends, and to upstream face dam body is promoted, and causes support bar to leave positive stop hook, and then the hydraulic cylinder of support bar bottom could rise,
Support root bottom part is lifted higher than at the top of positive stop hook, at this moment support bar is promoted under movable dam gravity pressure and the effect of water lateral pressure
Support bar bottom slips over positive stop hook, so that movable dam is progressively down on dam base surface, meets river course flood discharge.When running into movable dam
When top flood level is very high, supporting cylinder cannot promote movable dam body, cause support bar to leave positive stop hook, also just make
The hydraulic cylinder of support bar bottom cannot hold up support bar, so as to cause bed rearrangement dam body cannot flood discharge, separately plum rain season thunder and lightning frequency
Numerous generation, if thunder and lightning breaks the power system of hydraulic power unit, causing the control system of bed rearrangement movable dam cannot work, also
Be bed rearrangement movable dam cannot flood discharge, will so cause to cause the safety of the on-site people's lives and properties of engineering greatly hidden
Suffer from.
The content of the invention

Device, tripper steel plate is fabricated to closed box, and fully sheathed case Innerscoping cylinder, hydraulic cylinder piston rod top is provided with fan-shaped work
Dynamic steel plate sealer box top；Artificial control hydraulic cylinder declines, and sector movable plate is dropped on dam basic plane.Support bar solution
Locking device is untied, and support bar starts to slide backward.
The required technical problem for solving of the invention can be achieved through the following technical solutions.
A kind of movable dam support bar manual release device, including hydraulic cylinder groove, hydraulic cylinder trench bottom is provided with fixing bolt, institute
State and hydraulic cylinder is provided with hydraulic cylinder groove, the hydraulic cylinder groove on hydraulic cylinder top is provided with sector movable plate, and sector movable plate is by solid
Dead axle is connected with hydraulic cylinder groove, and the hydraulic cylinder groove of sector movable plate outside side is provided with positive stop hook, sector movable plate and
Positive stop hook coordinates with support bar bottom cross bar.
The sector movable plate is rotated around fixing axle.
The sector movable plate is rotated around fixing axle, and sector movable plate upper surface is in plane with hydraulic cylinder groove.
Beneficial effects of the present invention：A kind of movable dam support bar is unpowered tripper, is provided with hydraulic cylinder people in device
Industry control hydraulic cylinder declines, then is declined by hydraulic cylinder control sector movable plate, can complete support bar manual release control, hydraulic pressure
The cylinder groove top other end is equipped with positive stop hook, and control movable dam blocks water height.Its device has simple structure, flexible and convenient operation
The features such as.The potential safety hazard on dam can not drop when can efficiently solve flood discharge.
Description of the drawings
Fig. 1 is the unpowered tripper structure chart of support bar of the present invention；
Fig. 2 is the postrun structure chart of the unpowered tripper of support bar of the present invention.
Specific embodiment
For the technological means that the present invention is realized, character of innovation, reached purpose is easy to understand with effect, with reference to
It is specifically illustrating, the present invention is expanded on further.
As shown in Figure 1-2, a kind of movable dam support bar manual release device, including hydraulic cylinder groove 6, the bottom of hydraulic cylinder groove 6
It is provided with fixing bolt 5, the hydraulic cylinder groove 6 and is provided with hydraulic cylinder 4, the hydraulic cylinder groove 6 on the top of hydraulic cylinder 4 is provided with sector movable
Plate 2, sector movable plate 2 is connected by fixing axle 7 with hydraulic cylinder groove 6, the hydraulic cylinder groove 6 of the outside side of sector movable plate 2
Positive stop hook 1 is provided with, sector movable plate 2 and positive stop hook 1 coordinate with support bar bottom cross bar 3.
The sector movable plate 2 is rotated around fixing axle 7.
The sector movable plate 2 is rotated around fixing axle 7, and the upper surface of sector movable plate 2 is in plane with hydraulic cylinder groove 6.
Operation principle：
Positive stop hook 1 is fixed on the side at the top of hydraulic cylinder groove, and sector movable plate is mounted in hydraulic cylinder groove top, and one end is fixed on hydraulic pressure
The side on cylinder groove top, the other end is in hydraulic cylinder groove opposite side.Bottom is located at hydraulic cylinder top, and top is located under support bar cross bar
Face；Support bar 3 is located between positive stop hook and sector movable dam, and the bottom of hydraulic cylinder 4 is fixed on hydraulic cylinder trench bottom, and fan is withstood on top
Shape portable plate；Fixing bolt 5 is fixed hydraulic cylinder bottom portion, and the fixed sectors portable plate of fixing axle 7 makes sector movable plate and hydraulic cylinder
Groove 6 is fixedly connected；Hydraulic pressure groove 6 is fixed in dam foundation plinth, and top is equal with basic plane.
Slidably reciprocate to control support bar, two positive stop hooks are provided with the inside of support bar, two positive stop hooks are fixed on liquid
On cylinder pressure groove top；Positive stop hook controls support bar slid inward, while controlling dam body angle；Support bar outside is provided with one piece of fan
Shape portable plate, sector movable plate control support bar slides in and out.
Make sector movable for the ease of sector movable plate, hydraulic cylinder piston rod control in sector movable plate bottom is transported up and down
