Abstract

The utility model provides a buoyant self-control floodgate. A charging lifting mechanism is arranged in a corresponding water area at the bottom of a lifting gate [1]; the charging lifting mechanism comprises an air bag [9] and a cover [4] for facilitating the air bag [9] to open; the air bag [9] is connected with an air pipe [2] for controlling air inlet and outlet. After adopting the measure, the utility model can utilize the contraction and opening of the air bag to control the on and off of the gate. The floodgate provided by the utility model has the advantages of simple structure, convenient operation, small investment and low operation cost.

Description

Buoyancy autocontrol flood gate

Technical field

The utility model relates to a kind of water conservancy projects, is a kind of be used for controlling flood buoyancy autocontrol flood gate of flood discharge such as reservoir, river that is installed in specifically.

Background technology

Dykes and dams have generally all been built in existing reservoir, river, are used for retaining or change to flow to, to drink and field irrigation as people, animal.For the sake of security, the flood control floodgate is installed all generally on dykes and dams, water level surpasses certain altitude as to the water level alarm line time, will open a sluice gate and draw out some water.Be used for the lift lock of hydraulic engineerings such as reservoir, river, there is chute its both sides, but draining when gate moves up, and lock can be blocked water seal on earth the time downwards.This gate is according to the needs that vary in size, and the control lifting mode is also many, for some large and medium-sized gates, or adopts motor by transmission mechanism gate to be promoted, and this mode is invested greatly, operating cost is high; Or adopt manual operation that it is sling, but troublesome poeration, efficient is low, has potential safety hazard.

Summary of the invention

The purpose of this utility model provides a kind of simple in structure, easy to operate buoyancy autocontrol flood gate.

The buoyancy autocontrol flood gate that the utility model provides, it is that position, corresponding pool is equipped with an inflatable elevating mechanism in the bottom of lift lock, described inflatable elevating mechanism comprises that air bag and the open cover body of auxiliary balloon form; Described air bag is connected to the tracheae that is used to control its turnover gas.

Described cover body the inside is equipped with the colloid topping.

The base plate of cover body is a net structure.

At gate side and the corresponding position of water level alarm line overflow ducts is arranged, the outlet of corresponding overflow ducts is equipped with the hydraulic turbine, and the hydraulic turbine is connected with cylinder by transmission mechanism, and the gas outlet trachea of cylinder is equipped with the electromagnetic valve by water level control on tracheae; On the described air bag pressure limiting valve is installed.

After taking above-mentioned measure, can utilize the air bag air inlet to open the buoyancy of generation and the opening and closing that the exhaust rear gasbag shrinks regulating gate.It is simple in structure, easy to operate, investment is little, operating cost is low, security performance good, easily realize automation control.

Description of drawings

Fig. 1 is a structure chart of the present utility model;

Fig. 2 is the A-A of Fig. 1 and sectional view;

Fig. 3 is user mode figure of the present utility model.

The specific embodiment

With reference to Fig. 1, Fig. 2, Fig. 3, the buoyancy autocontrol flood gate that the utility model provides, it is in the position, corresponding pool, bottom of lift lock 1 an inflatable elevating mechanism to be installed, described inflatable elevating mechanism comprises that air bag 9 and the open cover body 4 of auxiliary balloon form, the big I of the shape of cover body 4 is decided as required, but gate 1 can be promoted after opening as long as guarantee air bag 9 air inlets, cover body 4 the insides are equipped with colloid topping 10, can reduce the abrasion of air bag 9, the base plate 11 of cover body 4 is a net structure, and water can directly contact with air bag 9; Described air bag 9 is connected to the tracheae 2 that is used to control its turnover gas.

At gate 1 side and the corresponding position of water level alarm line overflow ducts 8 is arranged, the outlet of corresponding overflow ducts 8 is equipped with the hydraulic turbine 7, the hydraulic turbine 7 is connected with cylinder 6 by transmission mechanism, the gas outlet trachea 2 of cylinder 6, electromagnetic valve 5 by water level control is installed on tracheae 2, and water-level probe can be installed in overflow ducts 8 the insides, anhydrous or institute's flow hour when overflow ducts 8, can open by water-level probe control electromagnetic valve 5, the gas of 9 li in air bag is discharged; On the described air bag 9 pressure limiting valve 3 is installed.

This tracheae 2 also can connect existing air pressure controlling organization, and this air pressure controlling organization can adopt prior art, have the air pressure controlling organization that fills degassing function.

Operating principle of the present utility model is: when reservoir, river level surpass certain altitude, water is discharged from the outlet of overflow ducts 8, the hydraulic turbine 7 rotates, drive 9 inflations of 6 pairs of air bags of cylinder by transmission mechanism, air bag 9 opens and produces buoyancy with gate 1 jack-up, sees Fig. 3, water is just discharged below gate 1, though the hydraulic turbine 7 is rotated further air bag 9 inflations, owing on the air bag 9 pressure limiting valve 3 is installed, can control the air pressure of 9 li in air bag; When reservoir, river level descend below overflow ducts 8, overflow ducts 8 anhydrous outflows or flow-rate ratio are less, the hydraulic turbine 7 stops operating, and water-level probe passes to electromagnetic valve 5 with information, and electromagnetic valve 5 is opened, 9 li gases of air bag are discharged by electromagnetic valve 5, air bag 9 shrinks, and gate 1 descends, and returns back to original position, see Fig. 1, realize drainning off floodwaters retaining.

Claims (4)
