Description
Technical field
The utility model relates to a kind of reservoir outlet gate, relates in particular to a kind of bottom outlet outlet gate of being convenient to control.
Background technology
[0002] various reservoirs are all provided with gate, and wherein realizing by bottom the gate discharging water is bottom outlet outlet gate, and its effect is that the water in reservoir is discarded to agricultural irrigation is carried out in Lower Reaches or as people's living water use.Existing bottom outlet outlet gate adopts plane steel gate, in its opening-closing process, drives door closure to move linearly at above-below direction by headstock gear by wire rope, and the realization that cooperatively interacts between door body opens and closes.Existing bottom outlet outlet gate will reach the normal use of the function that discharges water, and needs a large amount of supporting facility, such as building the hardwares such as a large amount of hydraulic structures, lock groove embedded part and pull bar; Meanwhile, because the head of bottom outlet outlet gate is higher, act on pressure on gate flap larger, so the hoisting capacity needing is also just larger, consume the energy many, running cost is high.
Summary of the invention
The purpose of this utility model is just to provide in order to address the above problem few, the required hoisting capacity of a kind of supporting facility little and be convenient to the bottom outlet outlet gate of controlling.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of bottom outlet outlet gate of being convenient to control, comprise a body and door closure, at the bottom of described door body level is installed on dam, the dewatering orifice at described door body middle part communicates with the culvert that discharges water at the bottom of described dam, described door closure be placed on described door body and be positioned at described dewatering orifice directly over, described door closure is connected with the headstock gear that is installed on dam crest by wire rope, described bottom outlet outlet gate also comprises break-in support, pivoted arm, free bearing, movable pulley and fixed pulley, described fixed pulley is installed on described break-in support, described movable pulley is installed on the first end of described pivoted arm, the second end of described pivoted arm is installed on the top of described free bearing by hinge, described free bearing be installed on described door body above, the first end of described wire rope is installed on the reel of described headstock gear, the second end of described wire rope is installed on the position near described fixed pulley on described break-in support after from top to bottom walking around successively described fixed pulley and described movable pulley again, the middle pars infrasegmentalis of described pivoted arm is connected with the top of described door closure.
In said structure, between pivoted arm and free bearing, form the relation that is rotatably connected, indirectly, between door closure and door body, form rotary opening and closing relation, the opening-closing process of door closure is relaxed more; Form the laborsaving haulage gear based on wire rope by fixed pulley and movable pulley, can in the situation that reducing tractive force, realize equally the keying of door closure.It is that wire rope break-in is to adapt to the effect of pivoted arm structure, so be named break-in support that above-mentioned break-in support plays.
Preferably, described break-in support is provided with the portal trestle of passage in the middle of being, the first end of described pivoted arm is through the passage in the middle of described break-in support.For supporting, fixed pulley and movable pulley are respectively two (being that pulley is 4 multiplying powers), and wire rope is two, jointly realizes the keying control to door closure.
In order to reduce the draft travel of wire rope, the first end of described pivoted arm is bent downwardly 10 °～45 °; Be preferably 30 °.In this case, the lift of headstock gear can be controlled in 6 meters of following keying controls that can realize door closure.
In order to overcome the gravity effect of wire rope, on the dam body outer wall between described headstock gear and described break-in support, buttress is installed, the top of described buttress is provided with fulcrum pulley, and described wire rope is walked around described fulcrum pulley.Like this, fulcrum pulley forms segmentation to wire rope and supports, to overcome the impact of wire rope gravity.
The beneficial effects of the utility model are:
The utility model, by adopting pivoted arm and free bearing to make door closure form rotary opening and closing relation between door body, is compared traditional above-below direction rectilinear movement on-off structure, can realize less hoisting capacity and complete the object that door closure keying is controlled; By fixed pulley and movable pulley are set, further reduce hoisting capacity; First end by pivoted arm is set to the structure that has a down dip, and has shortened the lift of headstock gear, has reduced the manufacturing cost of energy consumption and headstock gear; In addition, this bottom outlet outlet gate is simple in structure, and compact in design is easy to care and maintenance, has reduced the hardwares such as a large amount of hydraulic structures, lock groove embedded part and pull bar, has saved a large amount of manufacturing costs.
