Abstract

The utility model discloses a hydraulic automatic-controlled plate turning gate. The utility model comprises a gate body and support piers which are mutually matched and used, wherein the gate body is provided with a gate plate. The downstream side of the gate plate is provided with two support legs, each support leg is provided with two centering and rolling wheels which are centered on the support leg, and each support leg corresponds to one support pier. Each support pier is provided with a curved track which is used for the rolling wheels to roll. The shape of the curved track causes the gate body to be in a gate opening and flood discharging state or a gate closing state for adapting for the variation of the water flow, under the functions of self weight and water pressure. The rolling wheels on the support legs of the gate of the utility model roll on the curved tracks of the support piers, and the gate body is driven to move according to set parameters. When the utility model is required to reach different motion performances, the position of the roller and the curved tracks on the support piers can be adjusted in design, the sufficiently large adjusting space is provided, and thus the design parameters can be flexibly changed according to specific conditions. Due to the design flexibility, the operation performances of the gate with various operation performances can be ensured.

Description

Hydraulic automatically-controlled shutter gate

Technical field

The utility model relates to a kind of hydraulic automatically-controlled shutter gate, is used for Hydraulic and Hydro-Power Engineerings such as barrage and flood spillway.

Background technology

A few days ago, relatively extensively, its form is multifarious, each has something to recommend him in hydraulic automatically-controlled shutter gate application at home, and operating principle also all is based on the balance of water pressure and gate deadweight.All have cheap, unmanned advantage.But its runnability is unsatisfactory, and difference is also bigger, and when higher operating water level jacking was arranged in its downstream especially, general fluctuation of service was restricted its scope of application.

The utility model content

The purpose of this utility model is to provide a kind of operation stability, the wide hydraulic automatically-controlled shutter gate of the scope of application.

The utility model comprises sluice gate body and the buttress that cooperatively interacts and use, wherein sluice gate body has gate sheet, the downstream of gate sheet is provided with two supporting legs, each supporting leg is provided with two centering rollers that are centered on the supporting leg, the corresponding buttress of each supporting leg, the curve track that rolls for roller is arranged on the buttress, and the shape of curve track makes sluice gate body motion under deadweight and effect of water pressure be and open a sluice gate flood discharge shape or barrier gate shape to adapt to the current variation.

Principle of the present utility model is as follows: gate is supported on the curve track of buttress by the roller that is centered on the sluice gate body supporting leg, roller can roll on the curve track of buttress, drive the movement parameter that sluice gate body is set by us, if we will reach different runnabilities, can when design, adjust the position of roller and the curve track on the buttress, enough big adjustment space is arranged, so design parameters can change flexibly as the case may be.Because therefore the flexibility of this design can guarantee required various runnabilities.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is that the A of Fig. 1 is to view.

Fig. 3 is the another kind of structure chart of the utility model buttress.

The specific embodiment

The utlity model has sluice gate body 1 and buttress 2 as can be seen from Fig. 1 and Fig. 2, sluice gate body 1 has gate sheet 3, gate sheet 3 downstreams are fixed with two supporting legs 4 apart, two centering rollers 7 have been fixed on each supporting leg 4, this centering roller by be fixed on the otic placode 5 on the supporting leg, the hinge 6 on the otic placode 5 is connected with supporting leg 4, centering roller 7 can be that the heart freely rotates with hinge 6.Buttress 2 is fixed on the weir 8, and the corresponding buttress of each supporting leg has the curve track 9 that rolls for centering roller 7 on the buttress, and the shape of curve track 9 makes sluice gate body motion under deadweight and water pressure change to adapt to current, gate is opens a sluice gate flood discharge shape or barrier gate shape.Waterborne rising when sending out flood, can make sluice gate body in the automatic dextrorotation of curve track section of water pressure lower edge buttress then open a sluice gate flood discharge, know from experience because of deadweight when water level gate when falling and be rotated counterclockwise barrier gate barrage (water (flow) direction as shown in Figure 1) automatically along the curve track section of buttress.Curve track section 9 can be two sections full curve (see figure 1)s, also can be single hop full curve (see figure 3).

Claims

1, a kind of hydraulic automatically-controlled shutter gate, it is characterized in that this gate comprises sluice gate body (1) and the buttress (2) that cooperatively interacts and use, wherein sluice gate body (1) has gate sheet (3), the downstream of gate sheet (3) is provided with two supporting legs (4), each supporting leg is provided with two rollers (7) that are centered on the supporting leg, the corresponding buttress of each supporting leg (4) (2), the curve track (9) that rolls for roller is arranged on the buttress (2), and the shape of curve track (9) makes sluice gate body (1) motion under deadweight and effect of water pressure be and open a sluice gate flood discharge shape or barrier gate shape to adapt to the current variation.
