Description
Technical field
The present invention relates to a kind of fish gathering weir systems with fish rheotaxis research function, belong under hydraulic engineering background
Fish protection field.
Background technique
Rheotaxis is defined as the Behavior preference that fish generate water flow stimulation, and fish moves about down along water flow is referred to as negative
Rheotaxis, fish moves about upwards against water flow is referred to as positive rheotaxis.Fish pass structure design in the protection of hydraulic engineering Ecology
In, fish rheotaxis research is particularly important.To determine that impacted section crosses fish object, crosses fish mesh in fish pass structure design process
Mark spends fish season and crosses fish specification, and fish rheotaxis research is conducive to determine These parameters.
The research of fish rheotaxis can be divided into laboratory experiment method and two kinds of field investigation method.Laboratory experiment method is generally by view
Frequency monitoring test sink Mesichthyes traces back habit；The method of field investigation method has marine acoustics instrument monitoring method and video surveillance method
Deng.It is exactly that water environment is controlled for laboratory test disadvantage, can not accurately predicts that nature section Mesichthyes becomes to flowing habit；
For marine acoustics instrument monitoring, although the fish quantity by monitoring section can be monitored, it is difficult to distinguish fingerling class, and monitor
It is limited in scope；Simple video surveillance is not often selected since video camera monitoring range is small, but if video
Monitoring method combines other to block fish, lead fish measure, and monitoring effect and efficiency can be mentioned greatly.

Specific embodiment
Be described further below technical solution of the present invention, but claimed range be not limited to it is described.
As shown in figures 1-4, a kind of fish gathering weir system with fish rheotaxis research function, including block fish and lead fish device
With the flow channels 2 blocked fish and lead fish device side are set；It is characterized by: it is described block fish lead fish device include be located at river bank
The anchor block 11 on side is fixedly connected with gratings 12 on anchor block 11,14 (anchor block of grid 13 and aperture plate is equipped at intervals in gratings 12
11 and the fixed grid 13 of gratings 12 and aperture plate 14), i.e., setting is spaced between grid 13 and aperture plate 14；The flow channels 2, which are divided, is
Upper, middle and lower-ranking, upper layer are advection channel 21, and middle layer is fish-collecting box 23, and lower layer is monitor channel 22, and monitor channel 22 is located at
The side in advection channel 21, fish-collecting box 23 are mounted on the one end in advection channel 21；The monitor channel 22 and aperture plate 14, grid 13
It is adjacent.
Further, above-mentioned each component part can be removed and be connected as needed.
It is arranged in parallel between the grid 13 and aperture plate 14.
It is equipped with monitoring case in the monitor channel 22, camera 221, hydrothermograph and depth of water note are installed in monitoring case
Record instrument, camera 221 be mounted on monitoring case it is openable after cover, main purpose is that the stream that becomes of the impacted section fish of monitoring 3 is practised
Property, such as trace back (downlink) time (including season and round the clock), trace back (downlink) type, trace back (downlink) quantity, depth of water preference
Habit, while monitoring environmental element-water temperature by time point；
Further, from the point of view of the path that fish 3 are traced back, fish 3 can concentrate entrance under the action of blocking fish and leading fish device
To advection channel 21, the monitoring record of case is monitored into the fish 3 in advection channel 21.
The fish-collecting box 23 is the net cage 231 with horn mouth fish inlet.
According to the depth of water, the advection channel 21 can be divided into several channels；
Further, the advection channel 21 can carry out interlayer according to layout points depth of water situation, both meet take the photograph in this way
As 221 image pickup scope of head, and can be with 3 water layer preference of researching fish.
It is described to block fish to lead fish device trapezoidal, it is arranged on river bank.
The fish-collecting box 23 is mounted on along one end of water (flow) direction.
The section of the grid 13 is oval thin slice, is equipped with grid swing handle 131, grid 13 in the upper end of grid 13
360 ° of adjustings can be carried out by grid swing handle 131 with the angle of water flow；
Preferably, the upland water by grid 13 can change the direction of a stream of water at grid 13, will cause 13 periphery of grid
The disorder in flow field is traced back fish 31 under the influence of the secondary stream that physics intercepts and grid 13 manufactures, is drawn close to flow channels 2.
The gratings 12 and grid 13 pass through center axis connection.
The aperture plate 14 is the grid that pitch-row is 10~15mm；Fish 31 are traced back with further barrier to trace back and downlink fish
The effect of 32 uplink of class, so that fish 3 be guided to pass through from flow channels 2, the pitch-row size of aperture plate 14 can be according to being blocked fish 3
Size depending on.
In conclusion the present invention realizes the monitoring of cross-section of river tunneling boring, has studied impacted section fish and becomes to flowing habit,
Including tracing back (or downlink) fingerling, time that fish quantity and rheotaxis behavior occur (season and round the clock) and water temperature；And according to
Above-mentioned 3 rheotaxis monitoring data of fish to judge fish pass structure cross fish object, cross fish season, cross fish quantitative requirement, while this
The interim fish pass structure of fish uplink during system can be used as engineering construction.
