Description
Technical field
The utility model relates to tide analog technical field, is specifically related to a kind of tide test diving and pumps head piece anti-suck control device.
Background technology
Tidal model test is widely used in the Study on Problems such as waterway regulation, river mouth Water-related Project, salt water encroachment and contamination.And the tide generation system most important part that is tidal model test, generation system generates corresponding tidal flow according to tidal level and tidal characteristics.Tide generating mode mainly contains tail-gate overflow, vapour-pressure type tide box and pumps current control more both at home and abroad at present.Pump all sizes crossed the suction of control variables pump and discharge the water yield in model of the raw tidal system of stream, in Controlling model, water level height realizes tide analog process more.Pump the raw tidal system system of stream more and not only have higher tidal level degree of regulation, and cost performance is very high.Pump the raw tidal system system of stream according to tidal model test strength of current amount configuration water pump more; tide flow non-constant, moment change in process of the test; need according to actual conditions switch testing pump flow; thus the pump switch flowing raw tidal system system that pumps frequent more; easily produce siphon under water pump stopped status and take out the problems such as phenomenon, have a strong impact on tide analog precision.For solving inverted-siphon problem, most researcher adopts and water pump is gone out head piece and be promoted to more than the water surface and formed every vacating stream, but the method current impact greatly the water surface, cause water level fluctuation, reduce tidal level simulation precision.
Utility model content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of tide to test diving and pumps head piece anti-suck control device, inverted-siphon can be prevented, below the water surface can be submerged in again by going out head piece, greatly reduce water surface ripple, and adopt guiding device, water is flowed out more smooth-going, improve tide analog precision.
Technical scheme: for solving the problems of the technologies described above, tide test diving of the present utility model pumps head piece anti-suck control device, comprise fairing, elastic device and seal plate, described fairing is connected with the outflow tube going out head piece, described seal plate is hinged on fairing, one end of seal plate is connected with elastic device, and the other end of seal plate is connected with deflector; When water pump is out of service, in the raw, seal plate is at water flow pressure effect lower seal fairing, and during water pump operation, outflow tube water impact seal plate, fairing is opened, and current are from the smooth-going outflow of deflector for elastic device.
As preferably, described fairing comprises cylinder changeover portion and cuboid expanding section, and the internal diameter of described cylindrical section is identical with the external diameter of outflow tube.
As preferably, the height of described cylindrical section be the 2-5 of outflow tube external diameter doubly, the intracavity section of described cuboid section is rectangle, the length of side of inner chamber be the 1-2.5 of outflow tube external diameter doubly.
As preferably, described seal plate is long is 2-2.5 times of outflow tube external diameter, and wide is 1.2-2.3 times of outflow tube external diameter.
As preferably, described deflector is long is 2-3 times of outflow tube external diameter, widely equals seal plate width.
Beneficial effect: tide test diving of the present utility model pumps head piece anti-suck control device, has the following advantages:
1, efficiently solve and pump siphon under stream raw tidal system system termination of pumping state more and to draw water problem, avoid the water surface ripple that model internal cause water impact produces, significantly improve the precision of tide analog;
2, this utility model utilizes pipeline to go out the interaction cancellation of stream and the seal plate portion of energy of current, reduces the percussion of current;
3, this utility model employing guiding device induction current are smooth-going towards set direction goes out to flow, and makes water outflow flow path direction controlled, effectively improves flow-shape.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the present utility model;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the principle schematic that seal plate of the present utility model is opened;
The principle schematic that Fig. 4 position seal plate of the present utility model is closed.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figures 1 to 4, tide test diving of the present utility model pumps head piece anti-suck control device, comprise fairing 5, elastic device 4 and seal plate 2, described fairing 5 is connected with the outflow tube 1 going out head piece, described seal plate 2 is hinged on fairing 5 by articulated link chain 6, and one end of seal plate 2 is connected with elastic device 4, and elastic device 4 is fixed on fairing 5, elastic device 4 is preferably spring, and the other end of seal plate 2 is connected with deflector 3; When water pump is out of service, in the raw, seal plate 2 seals fairing 5 to elastic device 4, and during water pump operation, the water impact seal plate 2 of outflow tube 1, fairing 5 is opened, and current are from the smooth-going outflow of deflector 3.
In the utility model, fairing 5 top is changeover portion, and shape is cylinder, and internal diameter equals outflow tube 1 external diameter, is highly 2-5 times of outflow tube 1 external diameter; Bottom is expansion end, and shape is cuboid, and the length of side all gets 1-2.5 times of outflow tube 1 external diameter, highly equals changeover portion cylinder height.
In the utility model, seal plate 2 is long is 2-2.5 times of outflow tube 1 external diameter, and wide be 1.2-2.3 times of outflow tube 1 external diameter, and deflector 3 is long is 2-3 times of outflow tube 1 external diameter, widely equals seal plate 2 width.
The utility model in use, as shown in Figure 3 and Figure 4, the water impact seal plate 2 of the outflow tube 1 stretched out in model, seal plate 2 Unscrew water-flowing path, current flow out along deflector 3 from side direction, and now, elastic device 4 is in compressive state; When water pump is out of service, due to the effect of elastic device 4 and external water stream, seal plate 2 rotary closing water-flowing path, destroys the Production conditions that siphon is taken out, thus eliminates siphonage.The utility model not only can avoid the siphon of tidal model internal cause to take out the water surface ripple of generation, also utilize the portion of energy of current of the interaction cancellation between current and seal plate 2, and it is more smooth-going to adopt guiding device to make water flow out, so improve tide analog precision, improve tide analog playback effect.
The above is only preferred embodiment of the present utility model; be noted that for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
