Description
Technical field
The utility model relates to a kind of dam body gate, especially relates to a kind of dam body hydraulically operated gate.
Background technology
People usually build barrage on the river course, improve the river level water intaking, are used for field irrigation or hydroelectric generation etc.But during flood,, influence river flood control safety because barrage has been raised river level.In order to address this problem, at present retaining boxs and movable gates of adopting when moving flood season, can effectively reduce upper pond level more, reduce or avoid flood damage.Shortcomings such as though retaining box is safe and reliable to operation, there is the construction costs height in long service life, and is long in time limit, and opening and closing time is long.Dash stop gate particularly, construction costs is higher; Movable gate mainly contains hydraulic automatically-controlled shutter gate and rubber dam, hydraulic automatically-controlled shutter gate is simple in structure, construction costs is low, but there is following shortcoming: 1, gate panel downstream need be provided with buttress, the buttress foreign material of easily putting into gear during earial drainage, and be not easy to remove, cause the gate opening/closing difficulty, flood season, flood discharge reduced, dry season, seepage was serious, engineering can not be brought into play design efficiency, 2, during earial drainage, the oblique middle part, dam that is poured into of gate panel, reduced the flood discharge section with the buttress part, 3, during earial drainage, be subjected to cataract action, the gate panel is patted, seismism not can not get solving always.Be close to dam facing after the rubber dam emptying, do not reduce the flood discharge section, but the construction costs height, installation, maintenance technical requirements height, safety, reliability are relatively poor, and application life is short, and emptying and to fill the dam time longer.
The utility model content
Problem at retaining box and movable gate existence in the above-mentioned prior art, the utility model provides a kind of not only gate opening quick flexible, installation and maintenance convenience, safe and reliable to operation, and the dash water level can be regulated the gate flap formula hydraulically operated gate that construction costs is low again.
The technical scheme that the technical problems to be solved in the utility model is taked is: dam body is provided with several gate flap formula hydraulically operated gates that can make the dam body sealing mutually, described gate flap formula hydraulically operated gate can close and open successively, described gate flap formula hydraulically operated gate comprises hydraulic cylinder, plunger rod, the gate panel, rotating stand, rotating shaft and bearing pin, one side is provided with base body in the dam body downstream, on base body, be set with rotating stand, described gate panel lower end and rotating stand adopt minor axis to be movably connected, described gate panel can be around rotating the bearing rotation, in the hydraulic cylinder groove of dam body downstream one side, be provided with hydraulic cylinder, described hydraulic cylinder is provided with rotating shaft, described hydraulic cylinder can rotate around the axis, and the plunger rod on the described hydraulic cylinder is movably connected by bearing pin and gate panel.
Operating principle of the present utility model is:
By the Motor Drive hydraulic pump, pressurize to hydraulic medium, through the action of hydraulic control component control hydraulic cylinder, plunger rod stretches out, and jack-up gate panel rotates and be increased to design altitude around rotating bearing, meanwhile, after hydraulic cylinder rotates around the axis, and the gate panel is increased to design altitude one by one, closing direction control valve oil return pipe, make hydraulic cylinder keep rated pressure, form a checkdam; Open the directional control valve oil return pipe, utilize gate panel deadweight and the upper water pressure extremely fixedly dam facing elevation of gate panel that fell.Also can gate be fallen to corresponding height closing direction control valve oil return pipe according to upper pond level and letdown flow needs.
Gate flap formula hydraulically operated gate described in the utility model and existing movable gate are compared, and have following advantage:
1, after gate fell fully, can not block water by the same dam facing of being close to rubber dam gate, the foreign material of not putting into gear,
2, by the regulating gate panel height, can regulate upper pond level arbitrarily as backwater gate,
3, have the same lower construction costs of hydraulic automatically-controlled shutter gate,
4, installation, maintenance is simple and convenient, and is safe and reliable to operation,
5, the gate panel opens and closes flexible, quick.
