Embodiment 1

[0030] A pneumatic lifting flap dam, comprising a gate 1 arranged in a river channel, a support mechanism arranged in the channel and matched with the gate 1, a diversion mechanism arranged in the channel and matched with the support mechanism Groove 4, the fixing seat 36 that is arranged on the end of the guide groove 4 and cooperates with the support mechanism, the driving mechanism that is arranged on the fixing seat 36 and cooperates with the support mechanism, and the The power source 10 matched with the driving mechanism;

[0031] The support mechanism includes a support module 3 arranged on the fixed seat 36, a hinge seat 5 arranged on the gate 1, one end is connected with the hinge seat 5, and the other end is a support screw 2 matched with the support module 3 .

[0032] The support module 3 includes a support cylinder 35, the two sides of the support cylinder 35 are movably arranged on a right-angle fixed vertical surface through the rotating shaft 37, and the rotat...

Embodiment 2

[0039] The difference between it and the first embodiment is that: the gas source triple unit 6 is arranged on the air intake pipe 9 .

[0040] The air source triplet used in this embodiment, and a dryer is arranged at the front end of the air source triplet, which can dry the air, so that the air entering the air source triplet is clean air, and will not cause damage to the air motor. The service life of the air motor is extended, and the stability of the work is ensured. The support module used includes a support cylinder, and the two sides of the support cylinder are arranged on two right-angle fixed vertical surfaces through the rotating shaft, so as to realize the rotation support of the support screw. A rotating nut is set in the support tube, and the position change of the rotating nut on the support screw can be realized through the rotation of the rotating nut, and then the lifting of the gate can be realized. The matching bearings are thrust bearings. At the same tim...

Embodiment 3

[0042] The difference from the second embodiment is that the air outlet pipe 7 is in an inverted J shape.

[0043] The driving mechanism used in this embodiment includes an air motor unit located on the outer shaft of the right-angle fixed plate, a worm screw arranged on the output shaft of the air motor unit and matched with the worm wheel, and the high-pressure gas is pumped by the air motor Convert it to mechanical power, and then switch the good speed to the power output of larger torque. The worm gear can change the direction of power transmission and ensure the power output. The end of the worm is connected to the bearing through the The synchronous connecting rod on the rotating shaft outside the right-angle fixed plate is connected; this structure can rotate with the rotation of the support cylinder to ensure the best transmission position at all times, and the air motor unit used includes a protective case, through which It can be isolated from water to avoid the eros...

Abstract

The invention discloses a pneumatic lifting shutter dam and belongs to the technical field of water conservancy machines. The pneumatic lifting shutter dam comprises a gate arranged in a river channel, supporting mechanisms arranged in the river channel and matched with the grate, a diversion groove formed in the river channel and matched with the supporting mechanisms, fixing seats arranged at the end of the diversion groove and matched with the supporting mechanisms, a driving mechanism arranged on the fixing seats and matched with the supporting mechanisms, and a power source matched with the driving mechanism. Aiming at the phenomena that in the prior art, a hydraulic shutter structure is adopted, thus, an oil path pipeline needs to be arranged, and response is slow after operating; leakage is likely to occur after long-term using, and consequently, pollution occurs; and the investment cost is large, the pneumatic mode is adopted, the rapid response can be achieved, no medium costexists, pollution caused by leakage is avoided, maintenance is simple, the required pressure is small, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of water conservancy machinery and equipment, in particular to a pneumatic lifting flap dam. Background technique [0002] At present, what we usually call a flap dam is an intelligent hydraulic flap dam that has emerged in recent years and integrates machinery, electricity, and hydraulics. Most of the power transmission is hydraulic transmission, and other transmission methods are gradually eliminated. The hydraulic flap dam mainly uses hydraulic transmission to control the hydraulic cylinder to drive the gate to turn over to achieve the purpose of lifting water storage and drainage. A spoiler is installed on the top of the gate, and a rotating shaft is arranged at the bottom, and the rotating shaft is connected with the fixed hinge support. The back of the gate stretches out the piston rod of the hydraulic cylinder to lift the dam, and the piston rod of the hydraulic cylinder retracts to lower the dam; h...
