Description

Fish pass blockage resisting and floater in river centralized processor

Technical field

This utility model is related to the fish pass structure field of structural design in hydraulic engineering, anti-blocking in particular to a kind of fish pass Plug and floater in river centralized processor.

Background technology

The vertical continuity in river course after hydraulic engineering construction, has been blocked, hydrobiological existence and breeding has been affected.In order to subtract On hydrobiological impact, China's research worker has carried out numerous studies, such as fish gathering to fish pass structure for few hydraulic structure construction Ship, fish pass etc. under dam, foreign countries made the smooth migration of Fish by building fish passage, and defined rich experience.China is studied The engineering experience of personnel's also successive learning overseas, had built in some rivers and had crossed fish passage, but general effect was not good enough, particularly fish The blockage problem in road has had a strong impact on crosses fish efficiency；Additionally, the improvement of river drifting substances needs to expend a large amount of manpower and materials, and river In stream, changeable hydrologic regime is susceptible to contingency.Therefore design one kind be prevented from river drifting substances affect and can be by which The fish channel structure focused on after collection is particularly important.

Research in China in terms of fish pass is typically focused on the Hydraulic Characteristics of fish pass at present, for the blocking of fish pass Study on Problems is less, it is therefore desirable to which designing one kind prevents floating thing blocking fish pass water inlet and after can collect floating thing at concentration The device of reason.

Content of the invention

The purpose of this utility model is to provide a kind of fish pass blockage resisting and floater in river centralized processor, solve because Floating thing blocking fish pass and the low problem of the fish pass operational efficiency that causes, and river drifting substances disposing task can be taken into account, have It is beneficial to safeguard river environment safety.

For solving above-mentioned technical problem, the technical scheme for being adopted is this utility model：A kind of fish pass blockage resisting and river course Floating thing centralized processor, it include being installed on the drainage plate at the water inlet position of fish pass, and the drainage plate two ends respectively connect A floater shot is connected to, and aperture is offered in the floater shot and is set on slide bar；

The plane and angle formed by the wherein side fish pass aileron of fish pass that the drainage plate and slide bar are formed is obtuse angle, its The fish pass aileron of the fish pass that obtuse angle is located forms narrow section of beam with riverbank, and narrow section of downstream of the beam is provided with garbage pool, narrow section of the beam Water wheels are also equipped between garbage pool.

Preferably, the drainage plate is shaped as rectangle.

Preferably, the height of the slide bar is highly identical with fish pass.

Further, two slide bars are separately mounted to the both sides fish pass aileron end of fish pass.

Further, the length difference of the fish pass aileron of both sides is 1m.

Utility model works principle is as follows：

When the floating thing in river is floated to fish pass water inlet, the plane that formed due to drainage plate and slide bar and fish pass its Angle formed by middle side fish pass aileron is obtuse angle, so drainage plate can introduce floating thing in narrow section of beam, narrow section of beam can increase Flow rate of water flow, floating thing can be descending along narrow section of beam, and when water wheels, floating thing will be directed in garbage pool, narrow section of beam and rubbish There is certain drop between rubbish pond, therefore floating thing countercurrently can not go out, and floating thing is will focus in garbage pool.Work as river level During change, drainage plate also can fluctuate with the depth of water so that floating thing can not be entered in fish pass, at the same water conservancy diversion plate bulk compared with Little, do not affect Fish to trace back, therefore can reach fish pass and not block and do not affect the purpose that Fish are traced back, and garbage pool makes With the manpower and materials needed for the less river pollution treatment work of meeting, fish pass is enable really to play benefit and energy protecting ecology.

The beneficial effects of the utility model：This utility model solves the fish pass operation caused because floating thing blocks fish pass The low problem of efficiency, and river drifting substances disposing task can be taken into account, be conducive to safeguarding river environment safety.

Description of the drawings

Fig. 1 is the structural representation of a kind of fish pass blockage resisting and floater in river centralized processor；

In figure, fish pass 1, fish pass aileron 1a, water inlet 2, drainage plate 3, floater shot 4, slide bar 5, narrow section 7 of riverbank 6, beam, rubbish Rubbish pond 8, water wheels 9.

Specific embodiment

This utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.

As shown in figure 1, a kind of fish pass blockage resisting and floater in river centralized processor, it includes being installed on fish pass 1 Drainage plate 3 at 2 position of water inlet, 3 two ends of the drainage plate are respectively connected with a floater shot 4, offer in the floater shot 4 Aperture is simultaneously set on slide bar 5；

The plane of the drainage plate 3 and the formation of slide bar 5 is blunt with angle formed by the wherein side fish pass aileron 1a of fish pass 1 Angle, the fish pass aileron 1a of the fish pass 1 that its obtuse angle is located form beam narrow section 7 with riverbank 6, and narrow section of 7 downstreams of the beam are provided with garbage pool 8, the beam is also equipped with water wheels 9 for narrow section 7 and garbage pool 8 between.

The drainage plate 3 is shaped as rectangle.Its material can be organic material.

The height of the slide bar 5 is highly identical with fish pass 1.

Two slide bars 5 are separately mounted to the both sides fish pass aileron 1a ends of fish pass 1, the length difference of the fish pass aileron 1a of both sides It is worth for 1m.

The present embodiment operation principle is as follows：When the floating thing in river floats the water inlet 2 to fish pass 1, due to drainage plate 3 Angle formed by the wherein side fish pass aileron 1a of the plane and the fish pass 1 that are formed with slide bar 5 is obtuse angle, so drainage plate 3 can be by Floating thing is introduced in narrow section 7 of beam, and beam can increase flow rate of water flow for narrow section 7, and floating thing can be descending along narrow section of beam 7, through water wheels 9 When, floating thing will be directed in garbage pool 8, and beam has certain drop for narrow section 7 and garbage pool 8 between, and therefore floating thing can not be inverse Flow and go out, floating thing is will focus in garbage pool 8.When river level changes, as floater shot 4 can be kept afloat so that The drainage plate 3 being attached thereto also can fluctuate with the depth of water so that floating thing can not be entered in fish pass 1, while 3 body of deflector Product is less, does not affect Fish to trace back, therefore can reach fish pass 1 and not block and do not affect the purpose that Fish are traced back, and rubbish The manpower and materials required using the less river pollution treatment work of meeting in pond 8, enable fish pass 1 really to play benefit and can protect life State.
