Description
Technical field
The utility model relates to a kind of bottom outlet outlet gate, relates in particular to a kind of easy-opening bottom outlet outlet gate of opening step by step.
Background technology
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.Traditional bottom outlet outlet gate in the past will reach the normal use of the function that discharges water, and needs a large amount of supporting facility, and such as building the hardwares such as a large amount of hydraulic structures, lock groove embedded part and pull bar, construction cost is high; 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.
So, the inventor has invented the less bottom outlet outlet gate of few, the required hoisting capacity of a kind of supporting facility, and the main feature of this gate is that door closure and door body are designed to rotary on-off structure, and wherein door closure is connected with pivoted arm, on door body, free bearing is installed, pivoted arm is connected with free bearing.If but between door body, adopt general syndeton at door closure, because hydraulic pressure is very large, so although be rotary unlatching, still there is larger water resistance pressure, open still relatively effort.So in order to protect better the opening structure step by step of bottom outlet water dam of rotary opening and closing structure, we specially apply for separately this patent.
Summary of the invention
The purpose of this utility model is just to provide in order to address the above problem a kind of easy-opening bottom outlet outlet gate of opening step by step.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of easy-opening bottom outlet outlet gate of opening step by step, comprise a body, door closure, pivoted arm and free bearing, 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, the first end of described pivoted arm is installed on the top of described free bearing by the first 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 draws the second end of described pivoted arm, the middle pars infrasegmentalis of described pivoted arm is connected with the top of described door closure, the bottom of described pivoted arm is also provided with the second hinge and the 3rd hinge, described the second hinge is between described the first hinge and described the 3rd hinge, the top of described door closure is provided with corresponding the second axis hole and Triaxial hole, the internal diameter of described the second axis hole is slightly larger than the external diameter of described the second hinge, the bar hole of the ellipse shape that described Triaxial hole is above-below direction, described the second hinge and described the 3rd hinge are placed in respectively in described the second axis hole and described Triaxial hole, and described the 3rd hinge can move up and down in described Triaxial hole.
In said structure, between door closure and pivoted arm, pass through the second hinge and the 3rd stud connection, Triaxial hole is made as to bar hole, while making pivoted arm drive door closure to move up starting gate, first allow the 3rd hinge have one " zero load " mobile process, in this process, the second hinge is due to little with the second shaft hole matching gap, so can drive the corresponding position of door closure to move up, because the second hinge is near the first hinge and away from the second end of pivoted arm, so it is very large that it promotes moment, corresponding lifting force can be less, and this lifting force is the initial hoisting capacity of gate; After the 3rd hinge contacts with the top inner wall of Triaxial hole, the 3rd hinge can drive door closure to move up together, now, because door closure has been mentioned between door body and formed gap in one end of the second axis hole, so door closure is the hydraulic pressure during much smaller than whole sealing near the hydraulic pressure of one end top of Triaxial hole, the 3rd hinge is mentioned door closure and is become than being easier to.
Preferably, described the second axis hole and described Triaxial hole lay respectively at the position of described door closure top near two edges, and described the second axis hole is near described the first hinge.
Preferably, described Triaxial hole is 2～3 times of external diameter of described the 3rd hinge in the length of above-below direction.
The beneficial effects of the utility model are:
The utility model passes through at door closure and three hinges of pivoted arm set of time, and the Triaxial hole corresponding with the 3rd hinge is made as to bar hole, make the 3rd hinge in the time driving door closure, first have one section of " zero load " range ability, door closure is formed step by step in opening process to be opened, reduce the required hoisting capacity of starting gate, the unlatching of door closure is become easily, be beneficial to the keying control of bottom outlet outlet gate.
