Description
Technical field
The utility model relates to the fluid-velocity survey of fluid, the sensing technology that particularly a kind of three-dimensional flow of fluid is measured.
Background technology
Flow velocity is a very important parameter of fluid, measurement about flow velocity receives publicity always, its application is very extensive, meaning is also very great, such as observation Sea Current Real-Time Monitoring and measure time oceanographic survey a very important content, its timely prediction for weather has very large meaning.The equipment of measuring at present flow velocity is more, as mechanical type rotor flow sensor, and electromagnetic type flow sensor and hot film anemometer etc., but in use a ubiquitous problem is, structure is too complicated, and cost is higher, and need to regularly replace battery, these are all the places being left to be desired.
Utility model content
Technical problem to be solved in the utility model is, provide a kind of simple in structure, use stable and without the three-dimensional flow transducer of periodic replacement battery.
For solving the problems of the technologies described above, a kind of three-dimensional flow transducer that the utility model provides, comprise that being first of spatial three-dimensional position relation measures plate, the second measurement plate and the 3rd measurement plate, is provided with some ring-shaped distributed flow speed measurement sensors on described first, second, and third measurement plate; Described second measure plate with plate face vertical with ground and and the first measurement plate mode of being mutually upright position be connected in the upper end on the first measurement plate right side; The described the 3rd measure plate with plate face and and first lower end of measuring mode that plate be mutually upright position be connected in first measurement plate left side parallel with ground.
As the improvement of the utility model, described first measures the removable flexible connecting link that is connected with in plate bottom, described flexible connecting link bottom is connected with insertion rod, described insertion rod bottom is provided with transversal stretching bar, in described insertion rod, be also provided with tidal power generating device and ground signal receiving trap, be electrical connection between described first, second, third measurement plate and flexible connecting link, transversal stretching bar and tidal power generating device, ground signal receiving trap simultaneously.
Adopt after said structure mode, the utility model has the advantage of: three measurement plate structures that are three-dimensional structure connection are very simple, can measure easily flow velocity from three different angles; Consider seawater depth difference, flow velocity also can change to some extent, therefore be provided with the flexible connecting link that can change height; Tidal power generating device has solved the problem that when the utility model uses for a long time, power supply is supplied with well, need not regularly replace battery, and while insertion rod being inserted to fixture, transversal stretching bar opens to both sides simultaneously, can make contacting of the utility model and fixture more firm.
Brief description of the drawings
Shown in Fig. 1 is appearance assumption diagram of the present utility model.
Wherein: 1, first measure plate; 2, second measure plate; 3, the 3rd measure plate; 4, flow speed measurement sensor; 5, flexible connecting link; 6, insertion rod; 7, transversal stretching bar; 8, tidal power generating device; 9, ground signal receiving trap.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As shown in Figure 1, this three-dimensional flow transducer comprises that being first of spatial three-dimensional position relation measures plate 1, the second measurement plate 2 and the 3rd measurement plate 3, measures on plate 3 and is provided with some ring-shaped distributed flow speed measurement sensors 4 at the first measurement plate 1, the second measurement plate 2 and the 3rd; Second measure plate 2 with plate face vertical with ground and and the first measurement plate 1 mode of being mutually upright position be connected in the upper end on the first measurement plate 1 right side; The 3rd measure plate 3 with plate face parallel with ground and and first measure mode that plate 1 is upright position to be mutually connected in this connected mode structure in lower end in the first measurement plate 1 left side very simple, can measure easily flow velocity from three different angles.
First measures the removable flexible connecting link 5 that is connected with in plate 1 bottom, bottom at flexible connecting link 5 is connected with insertion rod 6, be provided with transversal stretching bar 7 in insertion rod 6 bottoms, in insertion rod 6, be also provided with between tidal power generating device 8 and ground signal receiving trap 9, the first measurement plates 1, the second measurement plate 2, the 3rd measurement plate 3 and flexible connecting link 5, transversal stretching bar 7 and tidal power generating device 8 and ground signal receiving trap 9 is electrical connection simultaneously.
The utility model, in the time of design, is considered seawater depth difference, and flow velocity also can change to some extent, therefore be provided with the flexible connecting link 5 that can change height; Tidal power generating device 8 has solved the problem that when the utility model uses for a long time, power supply is supplied with well, need not regularly replace battery; While insertion rod 6 being inserted to fixture (as seabed), transversal stretching bar 7 opens to both sides simultaneously, can make contacting of the utility model and fixture more firm.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
