Description

Folding sluice gate

Technical Field

The utility model belongs to the technical field of the hydraulic engineering technique and specifically relates to a roll over and roll over formula sluice gate.

Background

The sluice is the hydraulic structure that is commonly used in hydraulic engineering construction. In the prior art, the gate is operated by adopting a gate opening frame and a hoist arranged on the gate opening frame. However, the mode of setting the opening door frame to open and close the gate usually needs to occupy higher space, the height of the opening door frame above the ground level can reach 6-8 m, and some opening door frames are even higher, and some places can affect the landscape due to incoordination with the area. When the sluice is used for site selection, the situation that existing river-crossing buildings such as high-voltage electric wires, pipelines or other structures exist in proper sluice sites is often caused, so that the situation that the positions of sluice stations are overlapped with the positions of the high-voltage electric wires is often caused, the situation of building dense areas is more prominent, and if site selection is performed additionally, the manufacturing cost and the like are increased greatly, or proper sluice sites do not exist at all, so that great difficulty is caused to the overall layout of regional hydraulic engineering. In addition, most of the existing gates are of a lifting type, when the gates are in an opening state, the gates are suspended and placed in the air, and certain danger exists under the action of strong wind or external force.

SUMMERY OF THE UTILITY MODEL

The utility model provides a solve above-mentioned technique not enough and provide a roll over a formula sluice gate, realize that the roll over formula of gate goes up and down to open and close, reduce its required high space's purpose.

Wherein adopt multistage speed reduction in order to increase the output torque between hydraulic motor and the door, one of them level reduction gears adopts worm gear mechanism simultaneously, can have self-locking function when realizing slowing down, can remove power when opening to a certain extent and realize the auto-lock of door when a door. In addition, the height of a door should be less than the height of a door II, or the height of a door is as little as possible, and a door II is set according to actual requirements, and the structure can effectively reduce the output torque required by a hydraulic motor in the rotating process, and the rotating process is smoother and more stable.

A plurality of supporting blocks are arranged at the upper end of the downstream side surface of the first door. The supporting height of this supporting shoe is unanimous with the supporting height of hinge, so when No. two doors turn over to a door, its supporting shoe and hinge are located both ends respectively, and both all can keep basic horizontality when can keeping a door, No. two door framves on the gate pier, so can press the gravity between them on the gate pier totally, can not produce the power of other directions except vertical direction between a door, No. two doors.

The top surface of the gate pier is provided with a groove for laying a main hydraulic pipe and a branch hydraulic pipe. The design of this structure can ensure that hydraulic pressure house steward, hydraulic pressure divide the pipe to lay in the recess, and a door, No. two door turn over the in-process can not take place to interfere with hydraulic pressure house steward, hydraulic pressure between the branch pipe, and the stability and the security of equipment operation are high.

And a connecting shaft is fixed between the output shafts of the two hydraulic motors. The design of this structure can further promote hydraulic motor's power take off's synchronism, ensures that a door, No. two door turn over the synchronism and the stability at in-process both ends, avoids leading to the fact inconsistent torsion and damage to the both ends of a door along with the operation process is enlargied because of the small difference of hydraulic pressure in the branch pipe.

The plane where the threshold and the support threshold are located is inclined from top to bottom and upstream. According to the design of the structure, when the lock chamber is in a closed state, the first door and the second door are attached to the supporting threshold, and the lower end of the plane inclines upstream, so that the first door and the second door are obliquely arranged on the supporting threshold, and the first door and the second door can be tightly pressed on the supporting threshold and the threshold under the action of gravity, so that the water retaining performance is ensured.
