Further, a drain groove 61 is provided on the bottom surface side of the service profile 6.
The working principle of the invention is as follows:
in this design, unlike the installation mode of traditional main hydraulic hoist, traditional main hydraulic hoist is installed in the one side that is located the upper reaches of steel dam below driving chamber. When the steel dam gate is positioned at the water blocking position, the piston rod of the oil cylinder of the main hydraulic hoist is in an extending state for a long time.
The main hydraulic hoist is arranged on one side of the downstream of the driving chamber below the steel dam, so that when the steel dam gate is in a water retaining position, the piston rod of the oil cylinder of the main hydraulic hoist is in a contracted state for a long time, and the piston rod of the main oil cylinder can be protected. The locking mechanism in this design is identical to that used in conventional steel dams and therefore belongs to the prior art, and therefore its specific structure is not described in detail.
As shown in fig. 1, when the oil cylinder of the main hydraulic hoist in the design contracts, the steel dam crank arm drives the steel dam gate to rotate, and at the moment, the steel dam gate is vertical to block upstream water. When water is needed to be drained, the oil cylinder of the main hydraulic hoist is in an open state, the steel dam crank arm is in an open state, and the steel dam gate is in a horizontal state (a dotted line part in fig. 1). At this time, a dihedral angle formed between the steel dam crank arm in the contracted state of the cylinder of the main hydraulic hoist and the steel dam crank arm in the opened state of the main cylinder of the main hydraulic hoist is a, a=90°.
In the design, the original driving force of the hydraulic steel dam is provided by a main hydraulic hoist, the main hydraulic hoist is arranged in driving chambers at two sides of the dam body, and the driving chambers are arranged at the lower part of a bottom shaft. The main hydraulic hoist in the driving chambers at two sides drives the gate crank arm, and the crank arm drives the bottom shaft to rotate 90 degrees, so that the steel gate blade welded or bolted on the bottom shaft is driven to rotate 90 degrees. The gate is provided with a bottom water stop and a side water stop, so that water is stored when the gate leaves are erected and discharged when the gate leaves are fallen down.
In the design, a drainage groove is formed in one side of the bottom surface of the overhaul profile channel, so that accumulated water in the main hydraulic hoist can be drained through the profile channel. In the design, the steel dam gate is controlled by a sensor arranged on the main oil cylinder, and is in a horizontal position when the piston rod of the main hydraulic hoist extends out to the limit position; when the piston rod of the main hydraulic hoist is retracted to the limit position, the steel dam gate is in the vertical position.
As shown in fig. 2-4, in the design, a plurality of noise reduction gate leaves 102 are arranged on a gate body 101 of a steel dam gate 1, the noise reduction gate leaves 102 are provided with noise reduction gate seats 104, and the noise reduction gate seats 104 are arranged on noise reduction gate slot positions of the gate body 101 of the steel dam gate 1; the noise reduction gate leaf 102 is connected with a piston rod end of an auxiliary oil cylinder of the auxiliary hydraulic hoist 103, the auxiliary hydraulic hoist 103 is arranged on the gate body 101 of the steel dam gate 1 above the noise reduction gate slot, and a deflector 105 inclining downwards is arranged at the bottom end of the inner side of the noise reduction gate seat 104 to form a noise reduction mechanism of the steel dam gate.
When the traditional steel dam is used, when the steel dam is used for lying down and the top of the door is crossed, vacuum is formed behind the door, so that vibration and noise are generated on the door, and in order to solve the problems, a steel dam gate noise reduction mechanism is additionally arranged on the steel dam gate. The steel dam gate noise reduction mechanism in the design is characterized in that a plurality of small gates (noise reduction gate leaves 102) are added on original steel dam gate leaves, and the small gates are opened and closed by oil cylinders (auxiliary hydraulic opening and closing machines 103). When the steel dam is used for water flowing through the top of the horizontal gate, the small gate is opened first, so that vacuum can not be generated behind the gate when water flows through the small gate, and the problems of vibration and noise generated behind the vacuum generated behind the gate when water flows through the traditional steel dam gate are solved.
The beneficial effects of the invention are as follows:
(1) The hydraulic steel dam is not limited by space no matter in open field or in urban landscape engineering with road close to river.
(2) The steel dam is in the water retaining position for a long time, at this time, the piston rod of the main hydraulic hoist oil cylinder is in a retracted state, and the service life of the oil cylinder is longer.
The foregoing description is only of the preferred embodiments of the invention, and all changes and modifications that come within the meaning and range of equivalency of the features and concepts described herein are therefore intended to be embraced therein.
