Description
Technical field
The utility model relates to a kind of intake of hydropower station flow control structure.
Background technology
At present, in Hydraulic and Hydro-Power Engineering, powerplant intakes is separated into multiple runner with dividing pier usually, current are subject to the impact of channel of approach solid boundary, water inlet build and size and current self power condition, unequal by the flow of each runner, there is larger difference in split ratio, causes cross-sectional flow skewness.Design specifications requires that the flow velocity of power station inlet/outlet trashrack section should control at 0.8m/s ~ 1.0m/s, and maximum value can not more than 1.2m/s, and not allow to occur reverse flow, otherwise trashrack can be caused to vibrate and cause fatigue failure.CN202522123U discloses a kind of structure adjusting power station inlet/outlet runner split ratio, it is characterized in that, the upstream zone of power station inlet/outlet dividing pier or downstream section are provided with current divider.Although it can play the effect of shunting homogenising, also little to the regulating action contribution of flow velocity.
In view of this, need to invent a kind of novel kind intake of hydropower station flow control structure, it can control flow rate of water flow and the flow of water inlet, ensures that trashrack and generator normally work.
Utility model content
The purpose of this utility model is the defect overcoming prior art, provides that a kind of structure is simple, easy construction, effectively can control the intake of hydropower station flow control structure of streamflow regime in water inlet.
To achieve these goals, the technical scheme taked of the utility model is as follows:
A kind of intake of hydropower station flow control structure, its key technology is, it comprises the spaced water proof pier of two or more, sluice is formed between described two adjacent water proof piers, road junction, described sluice is provided with movable block water plate, both sides, described movable block water plate lower end are respectively arranged with shaft hole sleeve, rotating shaft is plugged with in described shaft hole sleeve, the two ends of described rotating shaft are fixedly connected with adjacent water proof pier respectively, rotating shaft between described two shaft hole sleeves is welded with pull bar, and the free end of described pull bar is provided with extension spring between described movable block water plate.
Further improve as the utility model, the side that described movable block water plate is relative with described sluice is provided with limited block.
Further improve as the utility model, each water proof pier linearly arranges.
Compared with prior art, the beneficial effect acquired by the utility model is as follows:
Intake of hydropower station flow control structure provided by the utility model, when current are by after runner, due to existence of the present utility model, when water is by sluice, can strike sideboard, according to the anxious slow degree of the difference of current, the intensity of impingement baffles is different, baffle plate folding and unfolding state can be made different, play the effect regulating current.The utility model structure is simple, and easy construction, can effectively control intake of hydropower station current.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is the utility model installment state top view;
Accompanying drawing 3 is the utility model installment state lateral view;
In the accompanying drawings: 1 water proof pier, 2 sluices, 3 movable block water plates, 31 shaft hole sleeves, 32 rotating shafts, 4 pull bars, 5 extension springs, 6 limited blocks, 10 runners.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed further describing is carried out to the utility model.
As shown in accompanying drawing 1,2 and 3, a kind of intake of hydropower station flow control structure, its key technology is, its bag is multiple with spaced water proof pier 1, sluice 2 is formed between described two adjacent water proof piers 1, road junction, described sluice 2 is provided with movable block water plate 3, and the length of movable block water plate 3 is advisable with the distance be greater than between two adjacent water proof piers 1.Both sides, described movable block water plate 3 lower end are respectively arranged with shaft hole sleeve 31, rotating shaft 32 is plugged with in described shaft hole sleeve 31, the two ends of described rotating shaft 2 are fixedly connected with adjacent water proof pier 1 respectively, on each movable block water plate 3, and rotating shaft 32 between described two shaft hole sleeves 31 is welded with pull bar 4, the free end of described pull bar 4 is provided with extension spring 5 between described movable block water plate 3, avoids current that movable block water plate 3 is blocked sluice 2.In order to avoid movable block water plate 3 falls down, the side that described movable block water plate 3 is relative with described sluice 2 is provided with limited block 6.The structure of linear adjustment current together with each water proof pier 1 is formed with movable block water plate 3.
Using method of the present utility model is as follows:
After current flow out in runner 10, the flow of the water in each runner 10 is unequal, when flowing through water flow control mechanism of the present utility model, current flow through movable block water plate 3, movable block water plate 3 is made to press to sluice 2, position residing for multiple movable block water plate 3 is different, and therefore, movable block water plate 3 can carry out transferring and rising by the environment residing for reality.Inflow in adjusted water channel and flow velocity, reach the function controlling current.The utility model structure is simple, easy construction.
The above embodiment is only preferred embodiment of the present utility model, and is not the exhaustive of the feasible enforcement of the utility model.For persons skilled in the art, to any apparent change done by it under the prerequisite not deviating from the utility model principle and spirit, all should be contemplated as falling with within claims of the present utility model.
