Abstract
The utility model relates to a hydraulic lifting dam characterized in that: a frame type base and a dam body that form a hinge structure with the base are provided, wherein the bottom edge of the dam body is articulated with the base through a hinge axis and a lambdoidal support frame is arranged between one side of the backwater of the dam body and the base. The rod body that forms a zigzag on the support frame is a hydraulic lifting pole and an H shaped movable double pole, while the H shaped movable double pole is divided into an upper section and a lower section, the middle of which is articulated. The utility model not only can reach the effect of lifting the rubber dam but also has overcome the defects that the rubber dam has a bad safety and reliability and at the same time the cost is greatly reduced.
Description
Technical field:
The utility model relates to the dam structure in the water conservancy projects, a kind of lifting dam of more specifically saying so.
Background technology:
For barrage retaining on the river, do not influence flood control safety again, the whole world generally adopts and can rise the rubber dam that can fall.But rubber dam is the cost height not only, and safety, reliability are relatively poor.
Summary of the invention:
The utility model is for avoiding above-mentioned existing in prior technology weak point, and a kind of low cost, safety is good, reliability is high hydraulic lifting dam are provided.
The technical scheme that the utility model technical solution problem is adopted is:
Design feature of the present utility model is the frame type base to be set and to form the dam body of hinge typed structure with base, described dam body is hinged by hinge axis and base on its base, between backwater one side and base of described dam body, " people " font bracing frame is set, what constitute " people " word on the support frame as described above is hydraulic lifting arm and H shape movable double-lever, described H shape movable double-lever is segmentation setting up and down, and is hinged at the middle part.
Design feature of the present utility model also is:
The described bracing frame that is made of hydraulic lifting arm and H shape movable double-lever is along the axially spaced-apart of hinge axis and set in a row.Described dam body, its dam crest portion is reclinate arc surface.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
The utility model can reach the effect of rubber dam lifting, has overcome rubber dam safety, the relatively poor shortcoming of reliability again, and cost greatly reduces simultaneously.
Description of drawings:
Accompanying drawing is the utility model structural representation.
Number in the figure: 1 base, 2 dam bodys, 3 hinge axis, 4 hydraulic lifting arms, 5H shape movable double-lever, 6 arc surfaces
By the following examples, in conjunction with the accompanying drawings the utility model is further described:
Embodiment:
Referring to accompanying drawing, frame type base 1 is set and forms the dam body 2 of hinge typed structure with base 1, dam body 2 is hinged by hinge axis 3 and base 1 on its base, between backwater one side and base 1 of dam body 2, " people " font bracing frame is set, what constitute " people " word on the bracing frame is hydraulic lifting arm 4 and H shape movable double-lever 5, and H shape movable double-lever 5 is segmentation setting up and down, and is hinged at the middle part.
When H shape movable double-lever 5 launched to be the upright body of rod of the two bar series connection shown in the figure along with the elongation of hydraulic lifting arm 4, dam body 2 rose and reaches maximum height; On the contrary, when H shape movable double-lever 5 when folding is closed up for two bars along with the shortening of hydraulic lifting arm 4, dam body 2 drops to minimum altitude.
In concrete the enforcement, H shape movable double-lever 5 for the bracing frame that constitutes by hydraulic lifting arm 4 and H shape movable double-lever 5 along the axially spaced-apart of hinge axis 3 and set in a row, the top of dam body 2 is reclinate arc surface 6.
Concrete enforcement need be beaten castinplace pile or squeeze into concrete prefabricated stake and be formed fulcrum on the riverbed, the cast reinforced concrete frame is as base 1 on the fulcrum.
If the riverbed ground is better, also can be behind the cleaning ground, directly the cast reinforced concrete frame forms base 1 on the riverbed.
For tens meters long dam bodys, can be designed to the dam body of an integral body; And for length more than hundred meters or highly be dam more than three meters, can dam body be set segmentation, overlap joint mutually between the adjacent dam body, interior rivet clasp leather hose sealing.
In the time of need carrying out dash, making 4 liftings of hydraulic fluid elevating lever by control system, promote H shape movable double-lever 5 and lift, is rotating shaft thereby promote dam body 2 with hinge axis 3, promptly drops into dash in the time of rising.
Needing flood passage or normally navigate when far away, is by control system the hydraulic fluid elevating lever to be regained equally, and H shape movable double-lever 5 is packed up, and drives dam body 2 and is hinge type and packs up, and bracing frame is covered by it simultaneously.
Can the float type switch be set in the korneforos, be used for controlling automatically the hydraulic fluid elevating lever of bracing frame, and then control dam body automatic lifting.Electricity can adopt Artificial Control.
