Abstract

The utility model discloses a shutter layered semi-automatic gate which comprises the following components: two restraining columns and two floats which are mounted on the two restraining columns. A No.1 flashboard, a No.2 flashboard and a No.3 flashboard are successively arranged and mounted between the two restraining columns from top to bottom. The No.1 flashboard is connected with the floats through metal ropes mounted on the fixed pulleys at two ends. The No.2 flashboard and the No.3 flashboard are respectively connected with a No.2 hoist and a No.3 hoist through a fixed shaft. According to the shutter layered semi-automatic gate provided by the utility model, each flashboard can be flexibly opened or closed or the opening angle can be adjusted according to different water level states, for realizing the purposes of water discharging, water obtaining in a layered manner, discharging sand, etc. The shutter layered semi-automatic gate further has the following advantages: simple and reliable integral structure, high automation degree, low maintenance cost, and facilitation for large-scale popularization and use.

Description

The semi-automatic gate of a kind of blinds layer-stepping

Technical field

The utility model relates to a kind of semi-automatic gate, especially a kind of novel semi-automatic gate of blinds layer-stepping.

Background technology

Central authorities were also increasing year by year for the investment of water conservancy along with file of central authorities clearly proposes to need to strengthen five aspects of water conservancy link in 2011, therefore for the maintenance of water conservancy projects with improve research and development and enjoy central authorities and hydraulic departments at different levels to pay attention to.

Existing hydraulic structure, the control of lift gate and Segment gate mainly relies on too loaded down with trivial details and more high-power headstock gear, caused bigger waste, its subject matter is mainly reflected in needs to be equipped with comparatively more professional's management, flood discharge is untimely, gate pier too much influences flood discharge etc., and from economic factor and gate manufacturing, maintenance and structure aspects considerations such as constructure scheme, overall cost, its effect is also often unsatisfactory in addition.

The utility model content

For addressing the above problem, it is a kind of simple and reliable for structure that the utility model provides, the semi-automatic gate of blinds layer-stepping that performance is good.

Realize the semi-automatic gate of a kind of blinds layer-stepping of the utility model purpose, comprise two constraint posts and two floats that are installed on two constraint posts;

Arrange up and down between described two constraint posts a flashboard, No. two flashboards and No. three flashboards are installed;

A described flashboard connects float by the metallic cable on the fixed pulley that is installed in its two ends, and described No. two flashboards are connected No. two headstock gears and No. three headstock gears by fixed axis respectively with No. three flashboards.

The semi-automatic gate of the described a kind of blinds layer-stepping of this patent, when upland water, float rises along the constraint post, after upper pond level exceeds the restriction water level, float impels a flashboard to rotate by the pulling force pulling fixed pulley rotation of metallic cable, and water will be by flowing out between a flashboard and No. two flashboards;

When water level fall back to designated water level and when following float will fall after rise, No. one flashboard cuts out automatically, like this, water level is remained at limit below the water level, satisfies the daily flood control retaining of reservoir demand;

When upland water is big, open No. two flashboards and No. three flashboards thereby can drive the fixed axis rotation by No. two headstock gears and No. three headstock gears in advance, increase bleeder quantity, will let out under the water level below the safety level, reservoir is in the safe flood control standard all the time;

Open No. two headstock gears separately, can adjust the angle of opening No. two flashboards, but stratified pumping;

Open No. three headstock gears separately, can freely adjust the angle of opening No. three flashboards, can arrange sand.

Comprehensively, this patent has following advantage:

1, float is according to the demand adjustable settings scope of water level, satisfies under the different weather conditions of Various Seasonal the demand of water level, guarantees that daily flood discharge controls flood, and reduces the demand of more multi-specialized personnel and equipment;

2, float links to each other with flashboard by linkage, reduces buoyancy for the requirement of float volume size;

3, the flashboard of middle part and bottom open and close separately, and can open different angles is as required satisfied under the bigger situation of upland water in advance with the needs of letting out under the water level below the safety level, fully guarantees the safety problem of dam body and reservoir;

4, upper shutter can be retained floating thing, and the middle part flashboard has the function of water intaking, simultaneously the effect that the flashboard of bottom can the row of playing sand;

5, the requirement for headstock gear reduces, and can reduce installation and the operation of loaded down with trivial details equipment such as large-scale headstock gear to greatest extent.

Description of drawings

Fig. 1 is the semi-automatic gate structures schematic diagram of a kind of blinds layer-stepping of the present utility model.

The specific embodiment

As shown in Figure 1, the semi-automatic gate of a kind of blinds layer-stepping comprises two constraint posts 1 and two floats 4 that are installed on two constraint posts 1;

Arrange up and down between described two constraint posts 1 flashboard 5, No. two flashboards 6 and No. three flashboards 10 are installed;

A described flashboard 5 connects float 4 by the metallic cable 3 on the fixed pulley 2 that is installed in its two ends, and described No. two flashboards 6 are connected No. two headstock gears 8 and No. three headstock gears 9 by fixed axis 7 respectively with No. three flashboards 10.

The semi-automatic gate of the described a kind of blinds layer-stepping of this patent, when upland water, float 4 rises along constraint post 1, after upper pond level exceeds the restriction water level, float 4 impels a flashboard 5 to rotate by pulling force pulling fixed pulley 2 rotations of metallic cable 3, and water will be by flowing out between a flashboard 5 and No. two flashboards 6;

When water level fall back to designated water level and when following float 4 will fall after rise, No. one flashboard 5 cuts out automatically, like this, water level is remained at limit below the water level, satisfies the daily flood control retaining of reservoir demand;

When upland water is big, thereby can drive fixed axis 7 rotations by No. two headstock gears 8 and No. three headstock gears 9 in advance and open No. two flashboards 6 and No. three flashboards 10, increase bleeder quantity, will let out under the water level below the safety level, reservoir is in the safe flood control standard all the time;

Open No. two headstock gears 8 separately, can adjust the angle of opening No. two flashboards 6, but stratified pumping;

Open No. three headstock gears 9 separately, can freely adjust the angle of opening No. three flashboards 10, can arrange sand.

Embodiment recited above is described preferred embodiment of the present utility model; be not that scope of the present utility model is limited; design under the spiritual prerequisite not breaking away from the utility model; various distortion and improvement that the common engineers and technicians in this area make technical solutions of the utility model all should fall in the definite protection domain of claims of the present utility model.
