Abstract

The invention discloses a gate which comprises a gate body (9) and a gate frame (10). The gate body (9) is mounted in the gate frame (10); the gate body (9) is connected with an on-off device for controlling on-off of the gate body (9); an overflow pipe (8) communicated with both sides of the gate is arranged in the gate body (9); a valve (11) for opening and closing the overflow pipe (8) is arranged on an opening at one side of the overflow pipe (8). Watertight rubber strips are mounted on both surfaces of the steel overhaul gate disclosed by the invention, so that bidirectional compression on the gate can be achieved; by adopting a novel discharge device, the problem of an excessively large friction force when the gate is opened and closed is solved; the gate is safe and reliable to open and close; discharging capacity can be regulated; after overhaul on downstream equipment is completed, impact of water flow to the downstream equipment is effectively reduced.

Description

A kind of gate

Technical field

The invention belongs to water treatment facilities, block upland water when relating generally to water lev el control and water treatment facilities maintenance, it is provided that the steel bulkhead gate of maintenance environment.

Background technology

Gate is as a kind of device for controlling water level.Conventional gate can be divided into cast-iron lock gate and steel gate by material, owing to steel gate intensity is high, lightweight.Simple structure does not need mould, and size is flexible.So the steel gate gate that to be water treatment field the most frequently used.Steel gate is to compress with gate frame under forward hydraulic pressure effect by sluice gate body surrounding rubber strip, thus reaching sealing effectiveness.If hydraulic pressure direction is reverse, rubber strip cannot compress with doorframe, and gate will be revealed, it is impossible to reaches stagnant water effect.If rubber strip is all installed on gate two sides, then when hydraulic pressure effect tail gates open and close, rubber strip is excessive with gate frame frictional force, and equipment very easily damages, it is difficult to normally use.After additionally the overhaul of the equipments in downstream completes, when tradition bulkhead gate is opened, upstream current moment sweeps away, it is possible to produces to impact to downstream water treatment facilities, equipment causes certain damage, operator are existed potential safety hazard.

Summary of the invention

The purpose of the present invention is contemplated to overcome the deficiency in conventional steel gate, it is provided that one can be suitable for different directions hydraulic pressure, and scalable vent flow reduces moment current when gate opening and, to upstream device, opens and closes safe and reliable steel bulkhead gate.

For solving above-mentioned technical problem, the technical solution used in the present invention is: a kind of gate, and including sluice gate body and gate frame, described sluice gate body is arranged in described gate frame, and described sluice gate body is connected to and controls the headstock gear that described sluice gate body opens and closes；The overflow pipe of gate both sides it is communicated with in described sluice gate body；A side opening of described overflow pipe is provided with the valve opening and closing described overflow pipe.

Described headstock gear includes headstock gear, travelling cradle and flap seat；Described flap seat is fixing with described sluice gate body top to be connected；Described travelling cradle is slidably mounted in described flap seat；Described travelling cradle is connected by drive screw with described headstock gear；Described valve is connected with bottom described travelling cradle.

Described travelling cradle offers elliptical slot, be provided with in described elliptical slot can slide in described elliptical slot rise revoke；Revoke for described and be surely connected with described flap seat.

It is connected by bulb suspension rod between described travelling cradle with described valve；Described bulb suspension rod one end is spherical, offers the ball recess matched with described bulb suspension rod on described valve.

Described sluice gate body is provided with waterstop pad in described finder outlet side.

Beneficial effect: compared with prior art, this utility model has the advantage that

1. the steel maintenance lock two sides of the present invention is all installed watertight rubber bar and can be realized bi-directional compression, adopts novel discharge device to solve frictional force problems of too during gate opening/closing, and gate opening/closing is safe and reliable.

2. regulating vent flow, downstream equipment effectively reduces current and upstream device is impacted after having overhauled.

3. having self-aligning function, reduce stress influence, service life of equipment is long, failure rate is low.

Detailed description of the invention

Below in conjunction with accompanying drawing, technical scheme is described in detail:

Fig. 1 is the side structure schematic diagram of the present invention.As it is shown in figure 1, the steel bulkhead gate of the present invention includes headstock gear 1, drive screw 2, travelling cradle 3, flap seat 4, bulb suspension rod 6, valve 11, waterstop pad 7, overflow pipe 8, sluice gate body 9 and gate frame 10.Sluice gate body 9 is arranged in gate frame 10, and both sides are mounted on sealing strip and coordinate with gate frame 10, and in the present invention, sealing strip adopts watertight rubber bar 13.Overflow pipe 8 is arranged in sluice gate body 9, and connects sluice gate body 9 both sides, and namely overflow pipe 8 connects upstream equipment and upstream device；Sluice gate body 9 top is provided with waterstop pad 7, and the side that namely sluice gate body 9 exports at overflow pipe 8 is provided with waterstop pad 7.Flap seat 4 is fixedly installed in above sluice gate body 9, is provided with slide rail in flap seat 4, and travelling cradle 3 is by sliding on the slide block 5 slide rail in flap seat 4.Bulb suspension rod 6 is connected with bottom travelling cradle 3, valve 11 offers a ball recess, and matches with spherical suspension rod 6；Valve 11 is arranged on the overflow pipe 8 mouthfuls at sluice gate body 9 top, matches with waterstop pad 7 for opening and closing overflow pipe 8 mouthfuls.Travelling cradle 3 upper end is connected with headstock gear 1 by drive screw 2, offers an elliptical slot in travelling cradle 3, is provided with rising of can sliding in elliptical slot and revokes 12 in elliptical slot, revokes 12 and fixes with flap seat 4 and be connected.

When gate opening, as shown in Figure 1, Figure 2, Figure 3 and Figure 4, when headstock gear 1 starts, first set drive screw 2 upwards to walk 10-50mm, drive screw 2 drives travelling cradle 3 and valve 11 to move up 10-50mm, and cone valve departs from waterstop pad 7, overflow pipe 8 UNICOM's gate both sides water level, and now rise and revoke the elliptical slot centre position that 12 positions are positioned on travelling cradle 3, therefore sluice gate body 9 is not taken away the face of turning up the soil.Therefore the head that gate water level is high flows to another side by overflow pipe can make gate two sides hydraulic pressure relative equilibrium, reduces head to gate pressure, solves gate two sides and installs that watertight rubber bar frictional force is excessive cannot open and close safely problem.Gate two sides hydraulic balance is after certain limit, headstock gear 1 continues to run with, rise and revoke 12 positions and be positioned under the elliptical slot on travelling cradle 3 edge, travelling cradle 3 continues up to slide, having driven and revoked 12 and move upward, thus driving sluice gate body 9 to be raised above, ground is left until gate fully opens in 9 times edges of sluice gate body, because gate two sides hydraulic pressure is through overbalance, upstream device moment impact is effectively reduced by current.

When closing gate, conducting oneself with dignity and under the thrust of drive screw 2 at sluice gate body 9, sluice gate body 9 moves down, until bulb suspension rod 6 couples with valve 11.As it is shown in figure 5, owing to bulb suspension rod 6 and valve 11 are sphere-contacts, there is self-aligning function, solve the drive screw 2 caused due to cumulative error and environmental effect deform, stuck problem, it is ensured that sluice gate body is of completely closed.
