Embodiment
As shown in Figure 1, the present invention is a kind of wave and tidal level proving installation, and it comprises fixed mount 1, some probe units 2, data acquisition board 3, computing machine 4.
Described fixed mount 1 is a root post, and its lower end is fixed on the bottom, surfaces in the upper end.Described fixed mount 1 also can be vertically fixed on the ocean platform.
Described 5 probe units 2 equidistantly are installed in the top of fixed mount 1, link to each other with data acquisition board 3 by signal wire, and data acquisition board 3 links to each other with computing machine 4.
As shown in Figure 2, described probe unit 2 is made up of two stainless steel metal probes 21 and an overcoat 22.Overcoat 22 is stretched out at described two stainless steel metal probes 21 intervals, parallel overcoat 22 two ends interior and stainless steel metal probe 21 that are set in, fill insulant 23(is as becoming column type or adopting other insulation filler to be fixed in the overcoat 22 with resin cast between two stainless steel metal probes 21 and overcoat 22), one end of stainless steel metal probe 21 links to each other with data acquisition board 3 by signal wire, the other end of stainless steel metal probe 21 is the voltage signal end of probe, the big portion in stainless steel metal probe 21 surfaces scribbles insullac, and only end of probe is exposed.
As shown in Figure 1, when described probe unit 2 was installed on the fixed mount 1, the plane, two stainless steel metal probe 21 places of probe unit 2 can remain on the surface level or become on the face of unspecified angle with level.
Work principle of the present invention:
When probe unit 2 is immersed in the seawater, because the seawater conductance is high, so has a very little voltage signal V between the exposed stainless steel metal probe 21 of two heads of probe unit 2
lWhen two stainless steel metal probes 21 were in air, because air insulation, therefore two stainless steel metal probes 21 had a very high voltage signal V
mWhen two stainless steel metal probes, 21 interruptions are immersed in the seawater, then intermittently height variation of the voltage signal of two stainless steel metal probes 21, voltage signal V to two stainless steel metal probes 21 carries out continuous acquisition, and then the voltage signal of two of the double end conducting probe bare metal probes is extremely shown in Figure 5 as Fig. 3 over time under the different situations.
As shown in Figure 1, the present invention has arranged 5 probe units 2, wherein probe unit 202 to 3 double ended probes of probe unit 204 in the hunting range of wave, their voltage signal can intermittently change by height, voltage signal can be as shown in Figure 5; Probe unit 21 is positioned at more than the crest, is exposed to all the time in the air, and then the signal of probe unit 201 is always high voltage, and voltage signal can be as shown in Figure 4; Probe unit 205 is positioned at below the trough, is immersed in all the time in the water, and then the signal of probe unit 205 is always low-voltage, and voltage signal can be as shown in Figure 3.Therefore, but wave height H approximate expression is that probe unit 202 is to the spacing between the probe unit 204, because probe unit 2 is at fixed mount 1(column) go up equidistant installation, the distance between two adjacent probe devices 2 is d, for instance graph, then wave height H is approximately equal to 2d.Wave period can be obtained over time by the voltage signal of probe unit 202 to any one probe unit 2 between the probe unit 204, and obviously wave period T is continuously the time interval (see figure 5) of two adjacent high voltage signals of appearance.
Apparatus of the present invention also can obtain tidal level (or water level) rule over time.Tidal level is defined as the height of seawater free surface fixed distance basal plane.Suppose to guarantee when installing that a certain probe unit 2 position height are fixed base (be fixed datum as Fig. 2 probe unit 205 positions), the seawater free surface is got the mean value of crest and trough, schemes at implementing, then the high F=of tidal level (3d+d)/2=2d.To tidal level continuous acquisition in time, just can obtain tidal level rule over time.Above data acquisition and calculating all can be finished by computing machine 4 programmings, can conveniently realize online data measurement in real time and monitoring.
Need to prove, measuring accuracy of the present invention depends on number and the installing space of probe unit 2, at fixed mount 1(column) probe unit 2 numbers installed are more many, distance is more little between the probe unit 2, then measuring accuracy is more high, and concrete stainless steel metal probe 21 numbers and spacing can require to determine according to actual conditions and measuring accuracy.
The above, only be preferred embodiment of the present invention, the quantity of probe unit can be decided as required, so can not limit scope of the invention process with this, the i.e. equivalence of doing according to the present patent application claim and description changes and modifies, and all should still belong in the scope that patent of the present invention contains.
