Description
Technical field
The utility model relates to a kind of equipment that prevents that the outdoor surge-chamber water surface in power station from congealing, and belongs to power station Hydraulic and Hydro-Power Engineering applied technical field.
Background technology
According to domestic construction of hydropower plant development, most engineering distribution, in western low temp area, has the advantages that the extreme lowest temperature is low, day and night temperature is large.The power station runtime has fluctuation except the unit load period surge-chamber water level that changes, and surge-chamber water level remains on same water level operation substantially, and surge-chamber water level fluctuation is less.If do not take antifreezing measures, power station is in the operation of low temperature period, and the outdoor surge-chamber water surface has the risk of congealing of freezing, and affects unit operation.Power station unit is not when the low temperature period, shutdown moved, and the surge-chamber water surface is the hydrostatic water surface, and when environment temperature is reduced to subzero, the surge-chamber water surface will freeze and congeal.While not moving for compressor emergency shutdown, can take the measure of emptying derivation conduit to avoid the water surface in surge-chamber to freeze.But for the engineering that pressure regulation facility is set, draw tail water road longer, runner emptying and water-filling last length, adopt emptying measure, easily reduce unit operation flexibility, affect power station adjusting function; Also can to surge-chamber top, add a cover antifreezely temporarily, but for major diameter pit shaft, must consider that top manhole cover structure strengthens and lifting facility is set, operation is inconvenience very.
Utility model content
For above technological deficiency, the purpose of this utility model is to provide that a kind of installation is simple, flexible operation, easy to maintenance, can effectively prevent the equipment that the outdoor surge-chamber water surface in power station congeals.
To achieve these goals, the utility model is by the following technical solutions:
A kind of equipment that prevents that the outdoor surge-chamber water surface in power station from congealing, comprise surge-chamber pit shaft, heat holding curtain, antifreeze lid, sub-truss, described sub-truss is embedded in surge shaft pit shaft top, antifreeze lid is arranged on sub-truss top, along sub-truss, within one week, be provided with heat holding curtain hook, described heat holding curtain is hung in heat holding curtain hook.
The double-layer color die mould EPS insulation sandwich board that described antifreeze lid is thick 10cm.
Described antifreeze lid stretches out 0.5～1.0m outside surge shaft pit shaft.
Described sub-truss is grid structure with bolt-sphere joints.
Described heat holding curtain adopts canvas and needling fiber cotton to process.
Described antifreeze lid is set to " cape type " longitudinal gradient structure of 5 °～15 °.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is installed simple, flexible operation, easy to maintenance, can effectively prevent that the outdoor surge-chamber water surface in power station from congealing; Its sub-truss adopts grid structure with bolt-sphere joints, and its stressed effect is good, and supporting capacity is strong, safe; Antifreeze lid adopts the double-layer color die mould EPS insulation sandwich board of thick 10cm, its high insulating effect, and cost is low; Antifreeze lid is set to " cape type " longitudinal gradient structure of 5 °～15 °, is beneficial to draining; Heat holding curtain adopts high-quality canvas and needling fiber cotton to be processed into, and high insulating effect is durable in use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is B place enlarged drawing in Fig. 2.
In figure: surge-chamber pit shaft 1, heat holding curtain 2, antifreeze lid 3, sub-truss 4, heat holding curtain hook 5.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in FIG. 1 to 3, the utility model is a kind of equipment that prevents that the outdoor surge-chamber water surface in power station from congealing, comprise surge-chamber pit shaft 1, heat holding curtain 2, antifreeze lid 3, sub-truss 4, described sub-truss 4 is embedded in surge shaft pit shaft 1 top, antifreeze lid 3 is arranged on sub-truss 4 tops, along sub-truss, within 4 one weeks, be provided with heat holding curtain hook 5, described heat holding curtain 2 is hung in heat holding curtain hook 5.
In order to make to be incubated better heat preservation, cost is lower, and described antifreeze lid 3 adopts the double-layer color die mould EPS insulation sandwich board of thick 10cm.
Described antifreeze lid 3 stretches out 0.5～1.0m outside surge shaft pit shaft 1, is convenient to draining, and surge-chamber pit shaft is played a very good protection.
In order to make stressed effect good, supporting capacity is strong, safe, and described sub-truss 4 adopts grid structure with bolt-sphere joints.
Described heat holding curtain 2 adopts canvas and needling fiber cotton to process, and its high insulating effect is durable in use.
For drainage effect is good, described antifreeze lid 3 is set to " cape type " longitudinal gradient structure of 5 °～15 °.
In work progress, according to pressure conduit parameter, calculate runtime surge-chamber breathing area (breathing area be pressure conduit flow area 9%), breathing area can be tried to achieve sub-truss from surge shaft overhead height divided by shaft in wall girth.
Surge-chamber ventilation passageway owing to changing for power station unit load between antifreeze lid and surge-chamber top, low temperature season heat holding curtain stacks when unit starting is closed by active hanging hook, can pull open heat holding curtain and play water body insulation effect in surge-chamber between stable operation of unit or down period; In the high temperature period, can dismantle heat holding curtain according to weather conditions.
