Description
Technical field
The invention belongs to hydraulic and hydroelectric engineering technical field, the ecological environmental protection technology being related in hydraulic and hydroelectric engineering,
It is specifically related to a kind of hydraulic and hydroelectric engineering fish pass structure and crosses fish number system.
Background technique
Hydraulic and hydroelectric engineering construction would generally have an adverse effect to aquatic ecological, especially to the influence of fish, mainly
Show as dam build cause river barrier, cause the living environment of the stock of fish to be compressed, to influence the stock of fish
Gene normal communication eventually leads to the stock of fish and peters out and disappear.
To slow down this adverse effect, fish pass structure, such as fish are usually set in hydraulic and hydroelectric engineering process of construction at present
Road, fishway, imitative nature channel etc..It is to objectively evaluate fish to set in the quantity that fish pass structure Mesichthyes upstream or downstream cross dam
An important indicator of effect quality is applied, and optimization and improved important evidence are designed to fish pass structure.
Fish effect is crossed for reflection fish pass structure, the current setting artificial observation room usually in fish pass structure carries out artificial
It counts, or is counted again after setting camera shooting, cause the error of artificial counting larger, especially count and lose caused by artifact
It is accidentally more frequent, seriously affect the accuracy and objectivity for evaluating fish effect.
Summary of the invention
To solve the above-mentioned problems, the present invention provides a kind of hydraulic and hydroelectric engineering fish pass structures to cross fish number system, from
And reached fish and count more accurate, reliable, efficient effect.
The present invention is achieved by following technical solution.
A kind of hydraulic and hydroelectric engineering fish pass structure crosses fish number system, including crosses fish pass, if the fish pass two sides of crossing are equipped with
Dry to count probe, the counting probe is connect with counter respectively, while being counted probe and counter while being connected to power supply.
Preferably, the counting probe is that infrared counting is popped one's head in.
Preferably, the counter is pulse counter.
Further, same to cross in fish pass, the quantity for counting probe is at least 3, and is uniformly distributed in fish pass
Entrance and outlet between.
Further, the probe that counts is staggered on the two sides side wall for crossing fish pass.
Further, the part of the surface popped one's head in and be exposed in fish pass that counts is cased with waterproof jacket.
Further, when counting at the entrance and exit that probe was located at fish pass, the counting probe was installed on fish
On the same side wall in road.
The beneficial effects of the present invention are:
A kind of hydraulic and hydroelectric engineering fish pass structure of the present invention crosses fish number system, compared with prior art, has
It is following the utility model has the advantages that
1. incuding correlation sensing device by infrared counting device to count fish quantity, counting is more accurate and reliable,
Overcome the error-prone defect of artificial counting；
2. uninterrupted continuous counter can be realized, final convenient for accurate evaluation fish pass structure crosses fish quantity, while can be anti-
Reflect aggregation extent of the fish in fish pass structure；
3. convenient to carry out, operation and maintenance are simple, are conducive to ecological environmental protection Facilities Construction.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
In figure: 1-, which is counted, to pop one's head in, 2- counter, 3- power supply, 4- fish, and 5- crosses fish pass, 6- waterproof jacket.
Specific embodiment
Technical solution of the present invention is further described with reference to the accompanying drawing, but claimed range is not limited to institute
It states.
As shown in Figure 1, a kind of hydraulic and hydroelectric engineering fish pass structure of the present invention crosses fish number system, including cross fish pass
5,5 two sides of fish pass of crossing are equipped with several countings probe 1, and the counting probe 1 is connect with counter 2 respectively, while counting spy
First 1 and counter 2 simultaneously connect with power supply 3, it can be achieved that uninterrupted continuous counter.
The counting probe 1 is popped one's head in for infrared counting, and the counter 2 is pulse counter.Infrared counting herein is visited
Head is reflection type infrared probe, i.e., emitting head, composition is an infrared probe together with receiving head and doing, and is had before probe
One object occurs that just the infrared reflection of emitting head is exported a pulse and counted to counter 2 to head, probe is received.It is infrared
It counts probe induction correlation sensing device and counts more accurate and reliable, the defect that artificial counting can be overcome error-prone.
Same to cross in fish pass 5, the quantity for counting probe 1 is at least 3, generally 3~10, and is uniformly distributed in
It crosses between the entrance and outlet of fish pass 5, arrangement spacing is evenly distributed by fish channel total length is crossed.Removed 5 entrance and exit of fish pass
Except the counting probe 1 at place, other, which count the data that 1 detection of probe obtains, can also reflect fish in the aggregation crossed in fish pass 5
Degree.
The probe 1 that counts is staggered on the two sides side wall for crossing fish pass 5；It was located at the entrance and exit of fish pass 5
Two count probe and 1 be installed on the same side wall of fish pass 5.
The part of the surface that 1 was exposed in fish pass 5 of popping one's head in that counts is cased with waterproof jacket 6, has good waterproof performance.
Fish pass structure cross fish quantity be finally with fish pass structure, including fish pass, fishway, imitative nature channel inlet with
For the count totals of exit detection device come what is counted, it is by crossing 5 first counting probes 1 of fish pass that uplink, which crosses fish quantity,
The reading of the counter 2 at place, it is that the last one counts the reading of the counter 2 at probe 1 by crossing fish pass 5 that downlink, which crosses fish quantity,
Number.
Embodiment one
When single fish passed through at 5 inlet section of fish pass, count probe 1 and detect fish 4 and pass through, flip-flop number 2 into
Row counts, when it is subsequent there is fish 4 to enter fish pass structure inlet section when, count probe 1 and detect fish 4 again and pass through, trigger again
Counter 2 counts, and realizes continuous stored counts.
Embodiment two
When it is sizable two or more a plurality of fish 4 side by side simultaneously passed through at 5 inlet section of fish pass when, enter
Counting probe 1 at mouthful is triggered, but since it passes through simultaneously side by side, the fish 4 that part fish 4 is counted 1 side of probe is blocked, and is counted
Number probe 1 can only be detected away from nearest fish 4 of popping one's head in is counted, and counter 2 is counted as one.But continue to go upward to other in fish 4
When group counts probe 1, since the upstream speed of fish is different, it can be detected successively by subsequent counting probe 1, to be recorded to
4 quantity of correct fish.
Embodiment three
Fish 4 will appear multiple phenomenon of turning back in fish pass 5 excessively, was arranged between 5 middle outlet of fish pass and entrance at this time
Counting probe 1 can detect the fish 4 of process repeatedly and generate counting, the quantity detected at this time can reflect fish in fish pass 5
The delay of class and aggregation extent.
Example IV
It is by crossing 5 first, the fish pass readings for counting the counter 2 at probe 1, finally that final uplink, which crosses fish quantity,
Downlink cross fish quantity be through mistake fish pass 5 the last one count probe 1 at counter 2 reading.Removed 5 entrance of fish pass and
Except the counting probe 1 in exit, other, which count the data that 1 detection of probe obtains, can also reflect fish in crossing fish pass 5
Aggregation extent.
