Description
Technical field
The utility model relates to a kind of power station inlet channel flow control device.
Background technology
At present, in Hydraulic and Hydro-Power Engineering, inlet channel place, power station drawn/impact of tailwater tunnel form and size and current self power condition, cause uneven water flow distribution in water channel.But in order to ensure the normal operation of generator, and the steady operation of trashrack, require that the flow velocity in the water channel of power station maintains in a constant range, otherwise the vibration of trashrack and generator can be caused 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 power station inlet channel flow control device, it can control flow rate of water flow in inlet channel, 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 power station inlet channel flow control device of water velocity in inlet channel.
To achieve these goals, the technical scheme taked of the utility model is as follows:
A kind of power station inlet channel flow control device, they more than three slide bars be parallel to each other comprising watertight shutter and be fixedly connected with inlet channel, the free end of described slide bar is provided with retaining part, described watertight shutter is provided with the slide opening matched with described slide bar, described slide bar is inserted in described slide opening, described slide bar is equipped with stage clip, and described stage clip is between described watertight shutter and described inlet channel.
Further improve as the utility model, described slide bar is four, is uniformly distributed in described inlet channel oral area.
Further improve as the utility model, described retaining part is retaining cap.
Compared with prior art, the beneficial effect acquired by the utility model is as follows:
Power station provided by the utility model inlet channel flow control device, can regulate flow of inlet water by the watertight shutter be arranged on into water road junction.When current are excessive, watertight shutter can be pushed away to inlet channel place, reduce the size of inlet channel water inlet, reach the function regulating flow velocity.The utility model structure is simple, and easy construction, can effectively control water velocity in inlet channel.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is sectional view of the present utility model;
Accompanying drawing 3 be of the present utility model reduce inlet channel and baffle plate distance after schematic diagram;
In the accompanying drawings: 1 watertight shutter, 2 slide bars, 21 retaining parts, 3 slide openings, 4 stage clips, 100 inlet channels.
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 power station inlet channel flow control device, it comprises watertight shutter 1 and the slide bar 2 parallel with four that inlet channel 100 is fixedly connected with, and fixedly builds respectively in the sidewall of the water inlet of inlet channel 100, and described slide bar 2 balances with inlet channel 100.The free end of described slide bar 2 is provided with retaining part 21, and the retaining part 21 in this detailed description of the invention is retaining cap, prevents watertight shutter 1 slippage.Described watertight shutter 1 is provided with the slide opening 3 matched with described slide bar 2, described slide bar 2 is inserted in described slide opening 3, and described watertight shutter 1 can horizontally slip along slide bar 2.Described slide bar 2 is equipped with stage clip 4, and described stage clip 4, between described watertight shutter 1 and described inlet channel 100, for carrying out spacing to watertight shutter 1, prevents watertight shutter 1 from blocking the import of inlet channel 100.
Using method of the present utility model is as follows:
When flow is excessive, water impact watertight shutter 1, makes watertight shutter 1 press to inlet channel 100, due to slide bar 2 being equipped with stage clip, therefore, watertight shutter can be avoided to block the import of inlet channel 100.Reduce the distance between watertight shutter and inlet channel, control inflow and the flow velocity of inlet channel, reach the function regulating flow velocity.The utility model structure is simple, easy construction.
It will be appreciated by those skilled in the art that the watertight shutter in the utility model is not limited to circle, can change according to the shape of inlet channel, can be square, trapezoidal etc.
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.
