Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.

The fishway inlet structure adapting to the downstream water level change comprises a water channel 1, wherein the upper end of the water channel 1 is vertically arranged, the lower end of the water channel 1 is arranged in a cambered surface manner, a fish passing mechanism is arranged in one end of the water channel 1 and close to the upper position, arc slopes 4 are arranged on two sides of the lower part of one end of the water channel 1, a blocking net 5 is connected to the inside of each arc slope 4 through a mounting component, a sunken underground tunnel 12 is arranged in the water channel 1 and corresponds to the position of the blocking net 5, and a plurality of groups of floating balls 9 are arranged between the underground tunnel 12 and the blocking net 5.

Can make blocking net 5 can be higher than the height of rivers through the arc slope 4 that sets up to carry out reasonable stifled operation of blocking, the waters area of its blocking net 5 below can be expanded through the gallery 12 that sets up, cause the activity that multiunit floater 9 can be more nimble in its gallery 12, with this when slowing down the impact of rivers, can not cause the jam of shoal of fish, floater 9 then is the lighter body material of general texture, when the shoal of fish contacts with it, can not cause outside mechanical damage, can slow down the impact of whereabouts.

Cross fish mechanism including installing the mount 2 on crossing the inner wall of ditch 1 both sides respectively, run through formula's spout 14 is seted up to 2 inboards of two sets of mounts, 14 inside equal slidable mounting of two sets of spouts have coupling assembling, coupling assembling's one end below all is provided with baffle 3, spout 14 can make things convenient for the coupling assembling that corresponds to slide inside it to this realizes the function of nimble roll adjustment, thereby adjusts according to the density of shoal of fish.

Coupling assembling is including all sliding at the inboard multiunit connecting block 7 that corresponds spout 14, corresponds baffle 3 and installs and correspond 7 one end lower position departments of connecting block, corresponds the inside multiunit connecting block 7 of spout 14 of sliding and can drive the baffle 3 of one end below and remove, causes the baffle 3 to shift.

Polylith baffle 3 all is the setting of staggering, 3 both sides outside along all being curved surface 6 settings of polylith baffle, and the one side outer wall that two sets of mounts 2 are close to each other all installs multiunit cassette 15, and card hole 8 has all been seted up to 15 inboard tops of multiunit cassette, 7 inboard tops of multiunit connecting block all move about the cartridge and have card post 13, many card post 13 one end below all runs through the cartridge and is corresponding card hole 8 inboardly, polylith baffle 3 through setting up can be according to the use of fishway, lure the shoal in one end, baffle 3 that curved surface 6 set up can protect the outside of shoal, cause when moving about, can not cause the damage because of rigid contact to the shoal, card post 13 and cassette 15 sliding fit, can carry out the screens to baffle 3 after the regulation is accomplished.

The installation component includes the mounting bracket 10 of fixed mounting in 5 one end tops of block, the mounting bracket 10 both sides are connected with arc slope 4 is inside through the cartridge spare that sets up, dead lever 11 is installed along the horizontal direction equidistance in 5 one end below positions of block, and the equal fixed connection in many dead levers 11 bottoms just is close to lower extreme department in crossing 1 inboard bottoms of ditch, can hold up the lower extreme of block 5 through many dead levers 11 that set up, cause behind the shoal of fish drainage, can not plug up the route of shoal of fish.

The cartridge includes the uniform symmetry cartridge at the inside gim peg of mounting bracket 10 one side, and two gim peg one end all extend to the inside of arc slope 4, through mounting bracket 10 and the gim peg that sets up, can be with the fixed setting between arc slope 4 in one end top of barrier net 5 to install barrier net 5.

Two side walls of the lower part of the water channel 1 are provided with side protective layers 16, and the bottom wall of the lower part of the water channel 1 is provided with a bottom protective layer 17; the protection layer 16 that wherein sets up can be for corrosion-resistant rubber buffering cotton pad, and end protection layer 17 can increase the gliding nature of ditch 1 diapire for planting the water moss in ditch 1 diapire, and when the upstream water volume was too little, the shoal is at the decline in-process, and protection layer 16 is owing to set up at the boundary wall to can improve the cushioning nature that individual shoal of fish dropped, reduce the damage that drops and cause, end protection layer 17 can reduce the shoal wearing and tearing damage that slides of shoal of fish simultaneously.

The working principle is as follows: the shoal of fish gets into from raceway 1 one end top, the user can adapt to the position of adjusting baffle 3 according to the density of shoal of fish, cause the shoal of fish to more adapt to the shoal of fish and use, correspond and slide baffle 3 in the outside of mount 2, then through the cooperation of calorie of post 13 with corresponding cassette 15, cause each baffle 3 can corresponding shift position, adjust the interval between the baffle 3 of crisscross two blocks of symmetries, the shoal of fish comes to lower extreme arc slope 4 position department along crossing the inside route of raceway 1, tunnel 12 corresponding to arc slope 4 position department inside can expand rivers, cause inside multiunit floater 9 under the screens of blocking net 5, can float in tunnel 12, from this can make the shoal of fish when falling to raceway 1 lower extreme, can slow down the impact force, cause the drainage of low reaches abrupt slope department more steady and safe, the impact that the shoal of fish whereabouquet whereabouts can not be very big, thereby make the rivers in the shoal of fish overall alleviate, do benefit to fish and move about.

The foregoing shows and describes the basic principles, essential features, and advantages of the invention.
