Abstract
The utility model provides an automatic opening and closing gate which takes buoyant force as power and used for automatic opening for flood discharge and automatic closing for water storage of water conservancy projects such as reservoirs and river dikes. The automatic opening and closing gate mainly comprises a curtain type gate, a water gate and a floating body. The floating body 7 is connected with a gate opening pull ring 5 by a steel wire rope 8 and is connected with the water gate 6 by a movable support rod 9. The automatic opening and automatic closing are realized according to the dynamic change generated by the buoyant force along with the fluctuation of water level.
Description
Technical field:
The present invention relates to a kind of automatic open and close lock that is used for hydraulic engineerings such as reservoir, dam, river.This automatic open and close lock is to borrow buoyancy for opening a sluice gate power ingeniously.Rely on the dynamic change of the buoyancy that buoyancy aid produces with fluctuation in stage to realize opening a sluice gate automatically flood discharge and barrier gate retaining.The invention still further relates to curtain-type sluice gate and the special-purpose rigid section and the flexible substrate of this automatic open and close lock.
Background technology:
At present reservoir, dam, river gate are the pure rigidity gate that concrete or ferrous materials are made, because gate is heavy, add that hydraulic pressure is very big; Open very difficulty, artificial unlatching is extremely slow, then can't open during deep water; Large-scale gate must rely on electric power to open, and causes electrical network impaired if meet with extraodinary flood, when not having supply of electric power; Also can't starting gate, there are major safety risks.Before this, I had once invented a kind of roller shutter type culverts and water gates door (patent No. IL200820054055.0), though can alleviate deadweight, decomposed hydraulic pressure, and gate opening power is reduced greatly, could open but need external force such as manpower or electric power to get involved.And said rigid section can not satisfy actual needs.
Summary of the invention:
The invention provides that a kind of what be used for hydraulic engineerings such as dam, reservoir river is the automatic open and close lock of opening a sluice gate power with buoyancy; It is characterized in that: the upper fixed of curtain-type sluice gate (4) is in the upper edge of sluice gate (6); Buoyancy aid (7) opens lock draw ring (5) through what wire rope (8) connected the curtain-type sluice gate below; Be connected with sluice gate (6) through movable brace rod (9), curtain-type sluice gate (4) is fixed in pliable and tough base (1) by many groups rigid section (2) with bolt (3) and constitutes.
In order to achieve the above object, curtain-type sluice gate as shown in Figure 2 can resolve into hydraulic pressure some part, and it is trapezoidal special-purpose section that its rigid section selects for use high weather resistance steel to be made into cross section, in fill foamed plastics, to reduce proportion.Its flexible substrate is a reinforcing material with wire rope and flaxen fiber, serves as to fill protective material with wear-resisting ageing-resistant vulcanized rubber, specifically design and produce by actual demands of engineering, on screw and draw ring are arranged, fill foamed plastics in the buoyancy aid, cover weather-proof wear-resistant protection material outward.Under be that wire rope connects and to open the lock draw ring, go up distance with movable brace rod maintenance and gate, sluice gate.Rope capacity confirms that according to normal pool level strut length is confirmed according to sluice gate height and fluctuation in stage amplitude.Actual water level is when normal pool level is following, and wire rope is lax, closing gate; When actual water level surpassed normal pool level, wire rope was tightened, and buoyancy increases, starting gate gradually, and flood discharge automatically, when water level fell after rise again, gate was closed under self gravitation and hydraulic action gradually.Automatically retain big vast tail, implement retaining.
Description of drawings:
Fig. 1 is for opening a sluice gate state diagram
Fig. 2 is gate structure figure.
Embodiment:
Fig. 1 opens a sluice gate state diagram for the present invention; Sluice gate 6 upper edges are fixed in curtain-type sluice gate 4 upper ends; Buoyancy aid 7 opens lock draw ring 5 through wire rope 8 connections, connects sluice gates 6 through movable brace rod 9.The length of wire rope 8 confirms that according to normal reserve-water-level strut 9 is confirmed according to sluice gate height and fluctuation in stage amplitude.When water level surpasses normal reserve-water-level, buoyancy aid 7 rise and wire rope is 8 stretching, tighten, buoyancy increases, starting gate 4 gradually.And along with the fluctuation of water level is opened big or the pass paddle.Rely on water pressure, gravity, buoyancy along with the dynamic change of water level realizes gate opening and the automatic adjusting of closing.Guarantee that flood discharge and retaining neglect neither.As shown in Figure 2; Curtain-type sluice gate 4 is fixed in flexible substrate 1 by many groups rigid section 2 with bolt 3 and forms, and the cross section of its rigid section 2 is trapezoidal, is convenient to very much roll; Help the suffered hydraulic pressure break into portions of whole gate, thus the required water pressure that overcomes when reducing gate opening greatly; Fill foamed plastics in the rigid section, its specific gravity control is being slightly larger than the scope of water.Reach the required gravity that overcomes when both alleviating gate and in water, opening, ensure that again gate 4 sinks naturally and hydraulic pressure is participated under, closes well under the lax state of wire rope 8.Fill the foamed plastics guarantee in the buoyancy aid 7 and can not reduce buoyancy because of water inlet.Strut 9 ensures that buoyancy aid does not collide itself collision and friction when reducing gate opening simultaneously with gate and sluice gate.
