Background technology
Aquatic ecological would generally be had a negative impact by Hydraulic and Hydro-Power Engineering construction, especially the impact on Fish, mainly
Show as dam build cause river course intercept, cause the living environment of the stock of fish to be compressed, thus have influence on the stock of fish
Gene normal communication, ultimately results in the stock of fish and peters out and disappear.
For slowing down this adverse effect, generally fish pass structure is set in Hydraulic and Hydro-Power Engineering process of construction, such as fish at present
Road, fishway, imitative nature passage etc..Crossing the quantity on dam in fish pass structure Mesichthyes upstream or downstream is that objective evaluation is crossed fish and set
Execute an important indicator of effect quality, be also the important evidence being designed fish pass structure optimizing and improving.
For the fish effect excessively of reflection fish pass structure, being typically, artificial observation room is set in fish pass structure at present and carries out manually
Counting, or count again after camera shooting is set, cause the error of artificial counting relatively big, the counting that especially artifact causes loses
The most frequent, have a strong impact on accuracy and the objectivity evaluating fish effect.
Summary of the invention
In order to solve the problems referred to above, the invention provides a kind of Hydraulic and Hydro-Power Engineering fish pass structure and cross fish number system, from
And reached fish and count effect more accurate, reliable, efficient.
The present invention is achieved by following technical solution.
A kind of Hydraulic and Hydro-Power Engineering fish pass structure crosses fish number system, including fish pass, if described fish pass both sides of crossing are provided with
Dry counting probe, described counting probe is connected with enumerator respectively, and counting probe sum counter is connected with power supply simultaneously simultaneously.
Preferably, described counting probe is popped one's head in for infrared counting.
Preferably, described enumerator is impulse scaler.
Further, in same fish pass excessively, the quantity of described counting probe is at least 3, and is uniformly distributed in fish pass
Entrance and outlet between.
Further, described counting probe is crisscross arranged on the both sides sidewall crossing fish pass.
Further, the part surface that described counting probe was exposed in fish pass is cased with waterproof jacket.
Further, when counting probe was positioned at the entrance and exit of fish pass, described counting probe was installed on fish
On the same sidewall in road.
The invention has the beneficial effects as follows:
A kind of Hydraulic and Hydro-Power Engineering fish pass structure of the present invention crosses fish number system, compared with prior art, has
Following beneficial effect:
1. counted fish quantity by infrared counting device sensing correlation induction installation, counted more accurately and reliably,
Overcome the defect that artificial counting is error-prone；
2. uninterrupted continuous counter can be realized, it is simple to the final of accurate evaluation fish pass structure crosses fish quantity, simultaneously can be anti-
Reflect Fish aggregation extent in fish pass structure；
The most convenient to carry out, operation maintenance is simple, beneficially ecological environmental protection Facilities Construction.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
In figure: 1-counts probe, 2-enumerator, 3-power supply, 4-fish, and 5-crosses fish pass, 6-waterproof jacket.
Detailed description of the invention
Further describe technical scheme below in conjunction with the accompanying drawings, but claimed scope is not limited to institute
State.
As it is shown in figure 1, a kind of Hydraulic and Hydro-Power Engineering fish pass structure of the present invention crosses fish number system, including fish pass
5, described fish pass 5 both sides of crossing are provided with some counting probes 1, and described counting probe 1 is connected with enumerator 2 respectively, counts spy simultaneously
1 sum counter 2 is connected with power supply 3 simultaneously, can realize uninterrupted continuous counter.
Described counting probe 1 is popped one's head in for infrared counting, and described enumerator 2 is impulse scaler.Infrared counting herein is visited
Head is reflection type infrared probe, i.e. emitting head is consisted of an infrared probe together with receiving head and doing, when having before probe
Just the infrared reflection of emitting head being counted to enumerator 2 to reception head, probe one pulse of output occurs in one object.Infrared
Counting probe sensing correlation induction installation counts more accurately and reliably, can overcome the defect that artificial counting is error-prone.
In same fish pass 5 excessively, the quantity of described counting probe 1 is at least 3, generally 3～10, and is uniformly distributed in
Crossing between the entrance of fish pass 5 and outlet, arrangement pitch is evenly distributed by crossing fish passage total length.Removed fish pass 5 entrance and exit
Outside the counting probe 1 at place, the data that other counting probe 1 detections obtain can also reflect Fish gathering in crossing fish pass 5
Degree.
Described counting probe 1 is crisscross arranged on the both sides sidewall crossing fish pass 5；It was positioned at the entrance and exit of fish pass 5
Two counting probes 1 be installed on the same sidewall of fish pass 5.
The part surface that described counting probe 1 was exposed in fish pass 5 is cased with waterproof jacket 6, has good water resistance.
The fish quantity of crossing of fish pass structure is finally with fish pass structure, including fish pass, fishway, imitative nature passage porch with
The count totals of exit detection device carries out adding up, and up fish quantity of crossing is through crossing 5 first, fish pass counting probe 1
The reading of the enumerator 2 at place, descending fish quantity of crossing is the reading through crossing the enumerator 2 at last counting probe 1 of fish pass 5
Number.
Embodiment one
When wall scroll fish is by crossing at fish pass 5 inlet section, counting probe 1 detects fish 4 to be passed through, and flip-flop number 2 enters
Row counting, when follow-up have fish 4 to enter fish pass structure inlet section time, counting probe 1 again detects fish 4 and passes through, and again triggers
Enumerator 2 counts, it is achieved stored counts continuously.
Embodiment two
When two or more a plurality of fish 4 sizable is the most simultaneously by crossing at fish pass 5 inlet section, enter
Counting probe 1 at Kou is triggered, but owing to it passes through the most simultaneously, part fish 4 is counted the fish 4 of probe 1 side and blocks, meter
Number probe 1 can only detect the fish 4 nearest away from counting probe, and enumerator 2 is counted as one.But continue to go upward to other fish 4
During group counting probe 1, owing to the upstream speed of fish is different, can be detected successively by follow-up counting probe 1, thus be recorded to
Correct fish 4 quantity.
Embodiment three
Fish 4 there will be, in crossing fish pass 5, the phenomenon turned back repeatedly, was now arranged between fish pass 5 middle outlet and entrance
Counting probe 1 can repeatedly detect the fish 4 of process and produce counting, the quantity now detected can reflect fish in fish pass 5
The delay of class and aggregation extent.
Embodiment four
Final up fish quantity of crossing is the reading through crossing the enumerator 2 at 5 first, fish pass counting probe 1, finally
Descending fish quantity of crossing be through crossing the reading of enumerator 2 at last counting probe 1 of fish pass 5.Removed fish pass 5 entrance and
Outside the counting probe 1 in exit, the data that other counting probe 1 detections obtain can also reflect that Fish are in crossing fish pass 5
Aggregation extent.
