Detailed Description
The invention is described in further detail below with reference to the following figures and specific examples:
the double-floating-box type ecological water-intaking folding gate device shown in fig. 1, 2 and 3 comprises a gate 1A, a gate 1B, a gate 1C, rollers 2, a hoist 3A, hoist 3B, L type components 4 (arranged in pairs in forward and reverse directions and restricted with each other), a floating box chamber 5, a floating box 6, a water inlet 7, a water outlet 8, a straight rod 9, an upstream river channel 10A, a downstream river channel 10B, a sealing gasket 11, a bottom plate 12, a lifting lug 13 and a movable steel plate 14.
The gate 1A is positioned on one side of the upstream river channel 10A, the gate 1B is positioned between the gate 1A and the gate 1C, and the gate 1C is positioned on one side of the downstream river channel 10B; the rollers 2 are respectively arranged on two sides of the gate 1A and the gate 1B, so that the gate and the gate pier can roll freely, and the gate 1A and the gate 1B can slide freely along with the lifting of the buoyancy tank 6. The hoist 3A is connected with the gate 1A, and when the gate 1A and the buoyancy tank 6 need to be overhauled, the hoist 3A lifts the gate 1A; the hoist 3B is connected with the gate 1C, and when the gate 1 needs to be overhauled and subjected to flood and silt flushing, the hoist 3B lifts the gate 1C. The L-shaped member 4 plays a role in fixing and restricting, so that the gate 1A can drive the gate 1B to ascend when ascending, and the gate 1B and the gate 1C cannot continuously ascend due to the restriction of the L-shaped member 4.
The buoyancy tank chamber 5 is positioned on two sides of the gate 1, and the buoyancy tank chamber 5 is sensitive to the change of the upstream water level; the buoyancy tank 6 is positioned in the buoyancy tank chamber 5, and the buoyancy tank 6 can freely move up and down according to the water level change in the buoyancy tank chamber 5; the straight rod 9 is a rigid straight rod, one end of the straight rod is connected with the buoyancy tank 6, and the other end of the straight rod penetrates through the gate pier to be connected with the top end of the gate 1A. A water inlet 7 is arranged on the side wall of one side of the buoyancy tank chamber 5 facing the water flow direction, and a water outlet hole 8 is arranged at the bottom of the side wall of one side of the buoyancy tank chamber 5 back to the water flow direction. The water inlet 7 can change the water level in the floating box chamber 5 according to the change of the upstream water level, and the water outlet 8 can slowly reduce the water level in the floating box chamber 5. The bottom surface of water inlet 7 is not higher than the initial top surface (being minimum water level line) of gate 1A, and the area of the section of intaking of water inlet 7 is far greater than the area of the section of leaving water of apopore 8, because apopore 8 sectional area is far less than the sectional area of water inlet 7, when the water level descends before the floodgate, gate 1 can slowly close, guarantees gate 1 job stabilization. The sealing gasket 11 is positioned at the bottom plate 12 of the lock chamber to play a role of water stopping, and the lifting lugs 13 are respectively positioned at the top end of the gate 1A and the top end of the gate 1C.
The movable steel plate 14 is respectively arranged at the bottom of the gate 1B and the gate 1C, and plays a role in supporting and lifting; when the movable steel plate 14 works (is in a horizontal state), the motor drives the rotating shaft 18 to rotate the movable steel plate 14 to be vertical to and fixed with the gate 1B and the gate 1C; when the movable steel plate 14 does not work (is in a vertical state), the motor drives the rotating shaft 18 to rotate the movable steel plate 14 to be horizontal to the gate 1B and the gate 1C and fixed; when the movable steel plate 14 works, the cuboid convex blocks at the end part of the movable steel plate 14 are tightly buckled with the grooves 19 at the bottoms of the gates 1B and 1C, so that the stability of the movable steel plate 14 is enhanced. The water stop 17 is arranged outside the L-shaped member 4 and functions as a water stop when the shutter 1 is moved.

When the water level is at a low level at the initial moment, the state of the gate is as shown in fig. 4 and 5, at the moment, the gate 1A, the gate 1B and the gate 1C are at the same elevation, the whole folding gate is in a folded state, the buoyancy force borne by the buoyancy tank 6 connected with the gate 1A is smaller than the sum of the dead weights of the buoyancy tank 6 and the gate 1A, and at the moment, only the gate 1A plays a role in retaining water.
When the water level is low and water needs to be taken, the gate 1A and the gate 1C are respectively lifted by the hoist 3A and the hoist 3B, and the gate B is also lifted simultaneously due to the restriction and the cooperation of the L-shaped components, so that the requirement of taking water at low water level is met.
2. Medium water level
When the water level gradually rises to a medium water level, the state of the gate is as shown in fig. 6 and 7, in the process, the buoyancy force borne by the buoyancy tank 6 is larger than the sum of the deadweights of the buoyancy tank 6 and the gate 1A but smaller than the sum of the deadweights of the buoyancy tank 6, the gate 1A and the gate 1B, so that the buoyancy tank 6 slowly rises to the final state of the gate 1 as shown in fig. 6, and at the moment, the L-shaped member 4 of the gate 1A and the L-shaped member 4 of the gate 1B are restricted and fixed;
when the buoyancy borne by the buoyancy tank 6 is gradually close to the sum of the deadweights of the buoyancy tank 6, the gate 1A and the gate 1B, the upstream water level gradually overflows the gate 1A in the process to obtain surface water, and in the state, the gate 1A and the gate 1B play a role in retaining water.
3. High water level
When the water level gradually rises to a high water level, the state of the gate is as shown in fig. 8 and fig. 9, in the process, the buoyancy force borne by the buoyancy tank 6 is larger than the sum of the dead weights of the buoyancy tank 6, the gate 1A and the gate 1B but smaller than the sum of the dead weights of the buoyancy tank 6, the gate 1A, the gate 1B and the gate 1C, so that the buoyancy tank 6 slowly rises to the final state of the gate 1 as shown in fig. 8, at the moment, the L-shaped member 4 of the gate 1A and the L-shaped member 4 of the gate 1B are restricted and fixed, the L-shaped member 4 at the other side of the gate 1B and the L-shaped member 4 of the gate 1C are fixed, and;
because the buoyancy borne by the buoyancy tank 6 is smaller than the sum of the dead weights of the buoyancy tank 6, the gate 1A, the gate 1B and the gate 1C, when the water level of the upstream rises, the water gradually overflows the gate 1A to take surface water, and in this state, the gate 1A, the gate 1B and the gate 1C jointly play a role in retaining water.
4. Drop of water level
When the water level is lowered from the high water level to the low water level, the operation of the gate 1 is reverse to that of the gate 1 when the water level is raised from the low water level to the high water level.
5. Flood-moving and silt-flushing
When flood discharging and silt flushing are needed, as shown in fig. 10 and 11, the hoist 3A and the hoist 3B work simultaneously to respectively lift the gate 1A and the gate 1C and lift the gate 1B, so that the height of the gate 1 is integrally increased to a section of the water surface line 15, and the flood discharging and silt flushing effects are achieved.
