Description
Technical field
The present invention relates to hydrophone is crossed, especially a kind of holding robustness crosses hydrophone.
Background technique
So-called " robustness " refers to that control system under the Parameter Perturbation of certain (structure, size), maintains certain performances
Characteristic.Robustness is closely related with system, is the holding of specific functionality when system is disturbed in face of environmental condition, i.e., with a kind of tool
Flexible mode maintains its operating modes.That is, robustness allows system structure and ingredient when being disturbed to occur
Certain variation, but its basic structure and specific function are kept.Keep a kind of different existing ways that specific function is realized
More, the robustness of system is stronger, this is because the failure of a certain mode can be remedied by other modes.
Summary of the invention
Hydrophone is crossed the technical problem to be solved by the invention is to provide a kind of holding robustness, by changing hydrophone
Internal structure overcomes tradition and crosses the very big disadvantage of hydrophone changes in flow rate when change of water level is larger, subtracts flowed fluctuation amplitude
It is small, made hydrophone that there is robustness.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is that: it is a kind of keep robustness cross hydrophone, packet
Inlet union, middle part runner and outlet connection are included, the reed that multiple groups structure is identical, is sequentially arranged is provided in the runner of middle part,
Every group of reed includes a upper reed plate and a lower reed, and upper reed plate inclination is fixed on the roof of middle part runner, with upper reed plate
Parallel lower reed inclination is fixed on the bottom wall of middle part runner, reed can with water flow change in flow along water flow direction
It swings, hydrophone was made to export to form stable water flow.
The upper reed plate and influent side tube wall angle are 30 °~60 °.
The root spacing of the upper reed plate and lower reed is 0.2 times of pipeline vertical height.
The upper reed plate end and lower reed end are respectively 0.5~0.87 with the tube wall distance change range of middle part runner
Times pipeline vertical height.
It is preferred that the inlet union and outlet connection are the identical inlet union round tube of a pair of of structure and outlet connection circle
Pipe, middle part runner are rectangular tube, are led to respectively between outlet connection round tube and rectangular tube between inlet union round tube and rectangular tube
The identical inducer circle change side's transition of a pair of of structure is crossed to connect with outlet section circle change side's transition.
The beneficial effects of the present invention are: overcoming tradition by changing hydrophone internal structure and crossing hydrophone in change of water level
Changes in flow rate very big disadvantage when larger, by optimizing its structure, it is ensured that change of water level is no more than under conditions of 50%, crosses hydrophone
Flow deviation is lower than 10%.
Detailed description of the invention
Fig. 1 is the structural schematic diagram for crossing hydrophone of the holding robustness of the embodiment of the present invention.
Fig. 2 is the perspective view of Fig. 1.
Specific embodiment
Invention is further described in detail with reference to the accompanying drawings and detailed description:
Holding robustness of the invention crosses hydrophone, including inlet union, middle part runner and outlet connection, in middle part runner
In be provided with the reed that multiple groups structure is identical, is sequentially arranged, every group of reed includes a upper reed plate and a lower reed, upper reed plate
Inclination is fixed on the roof of middle part runner, and the lower reed inclination parallel with upper reed plate is fixed on the bottom wall of middle part runner, spring
Piece can be swung with the change in flow of water flow along the direction of water flow, and hydrophone was made to export to form stable water flow.
The upper reed plate and influent side tube wall angle are 30 °~60 °.
The root spacing of the upper reed plate and lower reed is 0.2 times of pipeline vertical height.
The upper reed plate end and lower reed end are respectively 0.5~0.87 with the tube wall distance change range of middle part runner
Times pipeline vertical height.
As shown in Figure 1, 2, the inlet union and outlet connection are the identical inlet union round tube 1 of a pair of of structure and outlet
Connector round tube 2, middle part runner are rectangular tube 5, between inlet union round tube 1 and rectangular tube 5 and outlet connection round tube 2 and rectangular tube
It is connected respectively by the identical inducer circle change side's transition 3 of a pair of of structure and outlet section circle change side's transition 4 between 5.
Wherein, upper reed plate 6 and lower reed 7 and tube wall gap initial value are 35mm, and variable range is 25~43.5mm, upper spring
Piece 6 and tube wall angle initial angle are 45 °, and variable range is 30 °~60 °, duct height 50mm, upper reed plate 6 and lower reed 7
Portion horizontal space 10mm, as initial head 2m, rate of discharge 750 × 10-6m3/ s, when head h fluctuation range is ± 1m, out
Mouth flow q variation range is 680 × 10-6~810 × 10-6m3/s。
The present invention, under water (flow) direction effect of water pressure, reed and tube wall angle and reed are with pipe gap width with head
Change and change: when head pressure increases, reed and tube wall angle increase, and reed and the reduction of tube wall gap width, flow velocity are more initial
Level increases but effectively overflow section reduces；When head pressure reduces, reed and tube wall angle reduce, reed and tube wall gap width
Increase, flow velocity reduces but effectively area of passage increases.The present invention overcomes tradition and crosses hydrophone by changing hydrophone internal structure
The very big disadvantage of changes in flow rate when change of water level is larger, by optimizing its structure, it is ensured that change of water level is no more than 50% item
Under part, crosses hydrophone flow deviation and be lower than 10%.
The present invention overcomes tradition and crosses hydrophone changes in flow rate when change of water level is larger by changing hydrophone internal structure
Very big disadvantage.Thus reduce flowed fluctuation amplitude, made hydrophone that there is robustness, and can apply in drip irrigation technique, energy
Enough realizations are effective, automatically control flow.So that the flow by branch pipes at different levels is essentially identical, realize steady to crops
It is fixed, equably irrigate, increase irrigation efficiency and irrigation quality.
Embodiment described above is merely to illustrate technical idea and feature of the invention, in the art its object is to make
Technical staff it will be appreciated that the contents of the present invention and implement accordingly, patent model of the invention only cannot be limited with the present embodiment
It encloses, i.e., same changes or modifications made by all disclosed spirit are still fallen in the scope of the patents of the invention.
