Detailed Description

The invention will now be described in greater detail with reference to the accompanying drawings, which are simplified schematic drawings that illustrate, by way of illustration only, the basic structure of the invention and, therefore, only show the elements that are relevant to the invention.

As shown in FIGS. 1-4, large-aperture sinking composite double head flaps comprises a gate pier 1, a 0 reservoir 101 is arranged at the bottom of the gate pier 1, a 3 th hydraulic hoist 2, a second hydraulic hoist 3, a female head flap and a sub head flap , a th hydraulic hoist 2 and the second hydraulic hoist 3 are both arranged at the top of the gate pier 1, a female head flap is arranged in the 6 reservoir 101 and matched with the reservoir 101, a sub head flap reservoir 401 is arranged at the middle part of the female head flap , an th air chamber 402 and a water charging chamber 403 are arranged in the female head flap , the female head flap 04 is connected with the th hydraulic hoist 2, a sub head flap is arranged in the sub head flap 84 reservoir 401 and matched with the sub head flap reservoir 401, a second air chamber is arranged in the head flap , and a sub head flap 465 is connected with the second hydraulic hoist 501.

In order to ensure that the gate pier 1 has good mechanical property, the gate pier 1 is of a reinforced concrete hollow box structure.

In order to reduce the mass of the parent fly 4 and the child fly 5 and ensure the strength of plates, the parent fly 4 and the child fly 5 are both made of box steel structures and are welded by Q235B steel plates.

For stable lifting of the female fly 4, there are four hydraulic hoist 2, four hydraulic hoist 2 are disposed at the top end of the female fly 4 in a double-sided double hanging point.

For the purpose of stabilizing the lift sub door 5, there are two second hydraulic hoists 3, and the two second hydraulic hoists 3 are disposed at the top end of the sub door 5 in a double-sided single hanging point.

To reduce the mass of the parent leaf 4, there are four air compartments 402, four air compartments 402 in groups and located on either side of the library 401 of child leaves .

In order to lower the center of gravity of the mother leaf 4 and to stabilize the mother leaf 4 in water level arrangement, the water filling compartment 403 is located below the sub leaf reservoir 401.

In order to facilitate the lifting of the mother leaf 4 from the library 101, rollers 6 are provided on both sides of the mother leaf 4, and the mother leaf 4 and the library 101 are supported by the rollers 6.

In order to guide the lifting of the sub door 5 and to achieve a sealing effect, sliders 7 are provided on both sides of the sub door 5, and the sub door 5 and the female door 4 are supported by the sliders 7.

In order to improve the structural strength of the mother leaf 4, a top beam, a cross beam and a bottom beam are sequentially provided in the mother leaf 4 from top to bottom.

The working principle is that if the water levels of the upstream and the downstream are lower, only the female door 4 can be lifted to realize water retaining, when the water retaining is carried out, accumulated water in the water filling cabin 403 is drained, then the hydraulic hoist 2 is started to lift the female door 4 upwards to realize water retaining, and as the female door 4 is of a box steel structure, the th air cabin 402 and the drained water filling cabin 403 are arranged in the female door , the mass of the female door is greatly reduced, the starting force is reduced, and the hydraulic hoist 2 with double lifting points arranged on two sides can ensure stable and reliable lifting.

When the water retaining position needs to be lifted in the step, the sub-door leaf 5 can be lifted to retain water, when the water retaining position is retained, the second hydraulic hoist 3 is started, the sub-door leaf 05 continues to be lifted upwards at the height of the female door leaf 4 to retain water, the second air chamber 501 arranged on the sub-door leaf 5 can be used for balancing the self weight of the sub-door leaf, and the volume mass of the sub-door leaf 5 is smaller than that of the female door leaf 4, so that the second hydraulic hoist 3 arranged at the double-side single-lifting point can ensure the stable and reliable lifting of the sub-door leaf 5, the investment of equipment cost is reduced, and compared with the mode of retaining water through two staggered gates , the sub-door leaf 5 is embedded in the female door leaf 4 to achieve bidirectional water retaining, the water retaining effect is better, and the space is saved more.

When water retaining is not needed, water is filled in the water filling cabin 403, the mass of the female door leaf 4 is increased, the th hydraulic hoist 2 drives the female door leaf 4 to sink into the gate bottom plate reservoir 101, and water flow can pass through the groove of the gate pier 1.

The large-aperture sinking type primary-secondary double-door sluice adopts a mode that a secondary door 5 is embedded into a primary door 04, saves the whole space of the sluice , can flexibly adjust the water retaining height, has better water retaining effect, effectively solves the problems of overhigh single door body, larger warehouse 101, larger excavation amount and the like, can reduce force by the primary door 4 containing an air chamber and the secondary door 5, and can ensure stable and reliable opening and closing of the primary-secondary double-door sluice by the arrangement of the hydraulic opening and closing machine 2 and the 863 in the double-lifting-point arrangement.

The present invention is not limited to the above specific embodiments, and for those skilled in the art, the above conception can be used without any creative work, and all the changes made fall within the protection scope of the present invention.
