Description
Technical field
The utility model belongs to hydraulic engineering apparatus field more particularly to a kind of vertical water inlet vortex device of elimination.
Background technology
Currently,
In vertical intake pool, the operating condition of unit can usually change according to actual conditions so that intake pool
Original design parameter is unsatisfactory for existing operating condition, and the flow-shape in intake pool becomes disorderly, or even generates water surface whirlpool,
A large amount of air can be brought into water pump by water surface whirlpool so that water pump assembly high vibration is so that can not run, and have serious
Security risk.The rectification measure in intake pool mainly has following four at present：The whirlpool that disappears is set immediately below intake pool horn mouth
Cone, the whirlpool cone that disappears can fill up the slough under horn mouth, but the whirlpool cone that disappears of bottom does not have apparent eradicating efficacy to water surface whirlpool.
Underwater flat deck is arranged in intake pool, and underwater flat deck makes suction hose sucking flow velocity tend to be equal by the distance of extension flow direction-changing
Even, to prevent the generation of whirlpool, but it is smaller for the fluidised form disturbance around horn mouth, water surface whirlpool can not be played every
Disconnected effect.Intake pool rear wall partition wall is set in intake pool, left and right sides flow is made to enter horn mouth along partition wall, promotes loudspeaker
The flow velocity uniformity of mouth entrance, but this measure can not be eliminated only for the bad fluidised form caused by intake pool back wall distance
Water surface whirlpool.
In conclusion problem of the existing technology is：It cannot play the role of partition to water surface vortex, and cannot eliminate
Water surface vortex cannot be satisfied the needs of user.
Invention content
In view of the problems of the existing technology, the utility model provides a kind of vertical water inlet vortex device of elimination.
The utility model is realized in this way a kind of vertical water inlet vortex device of elimination is provided with：
Suction hose, cruciform baffles agitated vessel, horn mouth, horizontal cover board, annular vertical cover board.
The water suction inside pipe wall is connected with the cruciform baffles agitated vessel；The horn mouth is glued in the suction hose.
The horizontal cover board is welded in the suction hose；The annular vertical cover board is glued in the horizontal cover board.
The suction hose material therefor is stainless steel, and the cruciform baffles agitated vessel material therefor is high-strength ceramic, the loudspeaker
Mouth material therefor is polythene material, and the horizontal cover board material therefor is stainless steel, material used in the annular vertical cover board
Material is polythene material, and the type heart of annular vertical cover board is overlapped in the type heart of the suction hose.
Further, the radian that the horn mouth opens is 60 degree.
Further, suction hose is averagely divided into 4 inlet channels by the cruciform baffles agitated vessel.
Further, the walled thickness of the annular vertical cover board is 5 centimetres.
Further, the thickness of the horizontal cover board is 8 centimetres.
Further, the type heart of the annular vertical cover board overlaps installation in the type heart of the suction hose.
The utility model is simple in structure and design science, based on fluid mechanics principle and Design of Pump Station Theoretical Design
At, be to vertical water inlet eliminate vortex measure innovation.In the intake pool being vortexed there are the water surface, annular vertical lid is added
Plate, the flow before horn mouth by annular vertical cover board due to being stopped so that a part of flow is down around annular vertical lid
Plate enters horn mouth, and another part flow crosses horizontal cover board and enters horn mouth so that the water of bell-mouthed horn mouth front upper place
Energy exchange drastically occurs for stream, that is, destroys the condition of whirlpool generation, and the flow of water inlet is kept off by cross
It can form two symmetrical vortexs when plate, vortex lift-off backward is gradually withered away after this vortex is spread due to eddy viscosity,
Another vortex then continues previous vortex and becomes larger, and has at the vortex of previous extinction generate a small whirlpool at this time, slowly take off
Body diffusion is until extinction, is finally reached the purpose in the whirlpool that disappears.
Description of the drawings
Fig. 1 is the vertical water inlet vortex device structural schematic diagram of elimination that the utility model embodiment provides；
In figure：1, suction hose；2, cruciform baffles agitated vessel；3, horn mouth；4, horizontal cover board；5, annular vertical cover board.
Specific implementation mode
For that can further appreciate that the invention, features and effects of the utility model, the following examples are hereby given, and coordinates
Detailed description are as follows for attached drawing.
The structure of the utility model is explained in detail below in conjunction with the accompanying drawings.
As shown in Figure 1, the vertical water inlet vortex device of elimination described in the utility model embodiment includes：Suction hose 1, ten
Font baffle 2, horn mouth 3, horizontal cover board 4, annular vertical cover board 5.
1 inner wall of the suction hose is connected with the cruciform baffles agitated vessel 2；The horn mouth 3 is glued in the suction hose 1.
The horizontal cover board 4 is welded in the suction hose 1；The annular vertical cover board 5 is glued in the horizontal cover board 4.
1 material therefor of the suction hose is stainless steel, and 2 material therefor of the cruciform baffles agitated vessel is high-strength ceramic, described
3 material therefor of horn mouth is polythene material, and 4 material therefor of horizontal cover board is stainless steel, 5 institute of the annular vertical cover board
It is polythene material with material, and the type heart of annular vertical cover board 5 is overlapped in the type heart of the suction hose 1.
The radian that the horn mouth 3 opens is 60 degree.
Suction hose is averagely divided into 4 inlet channels by the cruciform baffles agitated vessel 2.
The walled thickness of the annular vertical cover board 5 is 5 centimetres.
The thickness of the horizontal cover board 4 is 8 centimetres.
The type heart of the annular vertical cover board 5 overlaps installation in the type heart of the suction hose 1.
The utility model is simple in structure and design science, based on fluid mechanics principle and Design of Pump Station Theoretical Design
At, be to vertical water inlet eliminate vortex measure innovation.In there are the intake pool in water surface whirlpool, addition annular vertical cover board 5,
Flow before horn mouth 3 is due to the blocking by annular vertical cover board 5 so that a part of flow is down around annular vertical cover board
5 enter horn mouth 3, and another part flow crosses horizontal cover board 4 and enters horn mouth 3 so that the horn mouth front upper place of horn mouth 3
Energy exchange drastically occurs for flow, that is, destroys the condition of whirlpool generation, and the flow of water inlet is by cross
Two symmetrical vortexs can be formed when baffle, vortex lift-off backward gradually disappears after this vortex is spread due to eddy viscosity
It dies, another vortex then continues previous vortex and becomes larger, and has at the vortex of previous extinction generate a small whirlpool at this time, slowly
