Abstract

The invention belongs to the field of machines, and discloses an electric control gate. The electric control gate is composed of a gate frame and a movable gate. The movable gate is composed of at least one gate shaft and gate leaves, wherein the gate shafts longitudinally penetrate through a gate frame cross beam transversely to divide the gate into two grids, and each grid is provided with one gate leaf fixedly connected with the corresponding gate shaft. Starting and closing equipment is composed of a three-phase power source control device, and an electric speed reduction device, a connecting rod and a pushing rod of the three-phase power source control device. The three-phase power source control device is composed of a sensor for determining the position of a fixing pin of a reduction gearbox rotary wheel, a computer and a relay. A signal input end of the computer is electrically connected with the position sensor. An output end is electrically connected with the relay. A three-phase motor is electrically connected with the relay. A gate shaft crank arm is movably connected with the pushing rod. One end of the connecting rod is movably connected with the pushing rod, and the other end of the connecting rod is movably connected with the fixing pin on the reduction gearbox rotary wheel. The computer controls the starting and closing equipment, the reduction gearbox rotary wheel rotates to drive the pushing rod to move left and right in a reciprocating mode, and therefore the gate shafts are linked and the movable gate can open and close the gate within the range of 0-90 degrees. The electric control gate is used for controlling water flow.

Description

A kind of automatically controlled gate

Technical field

The invention belongs to mechanical field, relate to a kind of automatically controlled gate specifically.

Technical background

Gate is used for closing and the open control device letting out (putting) aquaporin.The important component part of hydraulic structure, can in order to tackle current, controlling water level, adjust flux, discharge silt and drift etc.

Gate forms primarily of three parts:

1. subject activity part, in order to close or open aperture, common name gate, also known as gate flap;

2. solid part is buried;

3. opening and closing device.

Movable part comprises weighing structure, supporting walking parts, guiding and antipriming and the hangers etc. such as panel girder system.Embedded part part comprises backbone, guide rail, free bearing, lintel, ground sill, sealing seat etc., they are embedded in aperture periphery, firmly be connected with the concrete of hydraulic structure with dowel, formed respectively and supporting walking parts and sealing face on gate flap, so that the loads such as the water pressure of log type gate leaf and its being born pass to hydraulic structure, and obtain good gate sealing performance.Open/close machinery is connected with gate flap hanger, to operate the position controlling movable part, but also has minority gate to open and close by hydraulic automatism control operation.

Application number CN201110135297 Full-open type hydraulic control flap gate and using method thereof, solve the various drawbacks that traditional flap gate exists, and open and close accuracy and significantly improve, do not have shaking phenomenon, gate can not produce beating, float away phenomenon.

They are at shortcoming: the open-close sluice gate time at least needs more than 1 minute, quick and precisely can not control flow.

Summary of the invention

The object of this invention is to provide the automatically controlled gate of the one overcoming above-mentioned shortcoming.

The present invention is achieved through the following technical solutions.

A kind of automatically controlled gate, comprise gate and opening and closing device, gate is made up of gate doorframe and dodge gate, and dodge gate is made up of door-hinge and gate flap, at least one door-hinge is divided into two grids longitudinally through doorframe crossbeam gate, and each grid is provided with the gate flap that a slice is fixedly connected with door-hinge, opening and closing device is by three phase mains control device and electric speed reducer thereof, connecting rod, push rod forms, three phase mains control device is by the sensor determining reduction box runner steady pin position, computer, relay forms, Computer signal input is electrically connected with position sensor, output is electrically connected with relay, threephase motor is electrically connected with relay, door-hinge is cranked arm and to be flexibly connected with push rod, connecting rod one end is flexibly connected with push rod, the other end is flexibly connected with the steady pin on reduction box runner, opening and closing device is controlled by computer, reduction box runner rotating drive push rod bilateral reciprocation, thus interlock door-hinge makes dodge gate open-close sluice gate within the scope of 0 ~ an angle of 90 degrees.

Ground is provided with two bearing supports, and accompany a crankshaft crank between two bearings, a crankshaft end is connected with reduction gearbox output shaft power, and rod journal is flexibly connected with connecting rod.

Owing to have employed abovementioned technology, the present invention adopts to obtain following technique effect:

1, just can open-close sluice gate in 1 minute.

2, general-purpose computers quick and precisely control flow.

3, monomer gate open area can reach from 1 square metre to tens square metres, can realize large discharge and control.

Accompanying drawing explanation

Below accompanying drawing of the present invention is explained.

Accompanying drawing is operating principle schematic diagram of the present invention.

1. relay and three phase mains ABC, 2. computer, 3. gate doorframe, 4. dodge gate, 5. doorframe crossbeam, 6. door-hinge is cranked arm, 7. push rod, 8. connecting rod, 9. runner steady pin, 10. left stop and sensor, 11. right stop and sensors, 12. reduction boxes, 13. motor.

Detailed description of the invention

Below embodiments of the present invention are further described.

Because door-hinge can be divided into multiple grid gate longitudinally through doorframe crossbeam, force dispersion, so monomer gate open area can reach tens square metres, the control to large discharge water can be realized.

Left stop will equal the opening and closing stroke of dodge gate at 0 ~ an angle of 90 degrees to right stop distance.

In mechanism, the ratio of instantaneous input speed and output speed is called the gearratio of mechanism.Conventional reducer gearratio is generally less than 300: 1, when adopting the reducer comparing big speed ratio to be 300: 1, during motor speed 1000 revs/min, reduction box power output shaft often circles and just needs about 18 seconds, in other words, gate closes by reaching or only needs about 9 seconds by closing out.The greatly fast opening and closing speed crossing prior art gate.

Arranged by computer program, the opening and closing degree of regulating gate can also be facilitated, thus quick and precisely control flow.

Ground is provided with two bearing supports, and accompany a crankshaft crank between two bearings, a crankshaft end is connected with reduction gearbox output shaft power, and rod journal is flexibly connected with connecting rod.Here instead of runner with crankshaft crank, rod journal instead of steady pin.This is when need thrust ratio comparatively large, the technical scheme adopted when reduction box is difficult to bear, obviously, at this moment push rod push away or tensile load can all drop on two bearing supports, thus reduction box can be avoided easily to be damaged.
