Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, fish pass inlet device, including apparatus main body 110 and the floating drum being arranged on apparatus main body 110 120; Flexible connection mouth 111 and fish inlet 112,111 He of flexible connection mouth are respectively arranged on the both ends of described device main body 110 Fish inlet 112 is connected to the inner cavity of apparatus main body 110;It is provided with water pump 121 in the floating drum 120, is set on the water pump 121 It is equipped with exhaust pipe, the free end of the exhaust pipe is in outside floating drum 120.
Wherein, apparatus main body 110 is one of the main component of the fish pass inlet device, and inner cavity is round or rectangular channel Structure passes through for water flow, is generally made of light material, is preferably made of glass reinforced plastic.Mouth 111 is flexibly connected generally to be arranged In the upstream end of apparatus main body 110, for being attached with the downstream of fish pass 200, to guarantee the fortune of the fish pass inlet device Dynamic freedom degree;Being flexibly connected mouth 111 has impermeability, can usually be made of materials such as antiseepage film, rubber, glass reinforced plastics;Setting Reserved movement surplus is usually required when being flexibly connected mouth 111, to guarantee to can oneself after the fish pass inlet device is connect with fish pass 200 By moving.The reliability of the freedom and connection that move in order to balance, it is preferred that flexible connection mouth 111 includes bellows and sets The stainless steel interconnecting piece on bellows both ends is set, the bellows passes through the stainless steel interconnecting piece and apparatus main body in one end 110 are connected;Bellows is generally made of rubber or glass reinforced plastic.Fish are generally sailed against the current, and fish inlet 112 is that fish enter fish pass Across the entrance of water retaining structure;Whether the structure and its draft of fish inlet 112 are suitable, are that can fish can smoothly enter into fish The essential condition in road;In order to avoid fish are turned back, usually set pyramidal structure for fish inlet 112, and by its big opening end with Apparatus main body 110 is connected, and makes its input end of osculum end as fish inlet 112.
Floating drum 120 is one of the main component of the fish pass inlet device, main to be aspirated the water in river by water pump 121 Enter in floating drum 120 and realize with the weight for increasing fish pass inlet device, or is taken out the water in floating drum 120 by water pump 121 It drains into river and realizes the SEA LEVEL VARIATION for floating, and then adapting to block water buildings downstream to mitigate the weight of fish pass inlet device, Guarantee under different water levels that fish inlet 112 has draft appropriate, meets fish pass under different water levels into fish demand.In order to protect The stability of the fish pass inlet device is demonstrate,proved, a floating drum 120 usually is respectively set in the two sides of apparatus main body 110, totally two.Water Pump 121 is used for pump drainage water, can be to be a variety of, preferably immersible pump;Free end, that is, exhaust pipe disengaging water end (W.E.) of exhaust pipe, one As install the fish pass inlet device after, the underwater of river is submerged into the free end of exhaust pipe;Preferably, in the freedom of exhaust pipe It is provided with strainer on end, enters water pump 121 to avoid foreign matter.
As a kind of preferred embodiment of the utility model, which further includes controller and is arranged in device master Liquid level detector 130 in body 110, the liquid level detector 130 and water pump 121 are electrically connected with the controller respectively.Level sensing Actual water level that device 130 is able to detect in apparatus main body 110 simultaneously feeds back to controller, and normal low water level (N.L.W.L.) value is preset in controller With normal low water level (N.L.W.L.) value, normal low water level (N.L.W.L.) value is generally 1m, and normal low water level (N.L.W.L.) value is generally 2m.In operational process, when practical water When position is lower than preset normal low water level (N.L.W.L.) value, controller controls water pump 121 and the water in river is pumped into floating drum 120 to increase The weight of fish pass inlet device is realized, after actual water level is higher than preset normal low water level (N.L.W.L.) value, controller control water pump 121 stop working;When actual water level is higher than preset normal high water level (N.H.W.L.) value, controller controls water pump 121 will be in floating drum 120 Water is drawn in river and realizes floating with the weight for mitigating fish pass inlet device, when actual water level is lower than preset normal high water level (N.H.W.L.) After value, controller control water pump 121 stops working.The fish pass import is realized by setting controller and liquid level detector 130 For device according to the automatic adjusument of water level, automatic operating guarantees that fish inlet 112 has draft appropriate under different water levels. Liquid level detector 130 can be to be a variety of, preferably liquidometer;By being respectively set on two medial surfaces of apparatus main body 110 One liquidometer, totally two;Two liquidometers respectively correspond respective water pump 121 in two floating drums 120.
In conjunction with shown in Fig. 2 and Fig. 3, the fish pass makeup of the imports, including fish pass 200 and any one above-mentioned fish pass import dress It sets;The fish pass inlet device is connect by being flexibly connected mouth 111 with the downstream of fish pass 200.Blocking water buildings downstream water In the biggish situation of level amplitude, the position for sinking or floating by adjusting fish pass inlet device, to guarantee under different water levels into fish Mouthfuls 112 have draft appropriate, can meet the fish pass under different water levels into fish demand, multiple and different height that no setting is required Fish inlet, simplify the operation and management mode of fish pass, and saved construction and maintenance cost.
In order to slow down the water velocity in fish pass 200, in favor of fish migration, then as shown in Fig. 2, in fish pass 200 Two medial surfaces on be provided with unhurried current part 210, and the unhurried current part 210 on 200 two medial surfaces of fish pass misses one another.Unhurried current Part 210 is used to block a part of cross section of fish pass 200, to reduce water velocity;It typically is the gears being arranged in fish pass 200 Plate or partition.In order to guarantee that fish can smoothly sense the water flow in fish pass 200, need to guarantee two unhurried currents of arbitrary neighborhood There are certain gaps in water (flow) direction for part 210.
