Technical Field

The invention relates to the field of hydraulic engineering and environmental protection engineering, in particular to a bidirectional fish passing ship lock and an operation method thereof.

Background

In order to meet various requirements of flood control, irrigation, power generation and the like, a river blocking building needs to be built on a natural river channel. Although river barrage brings great convenience to people in production and life, other problems are brought along with river barrage. The river-blocking building blocks not only passages for migration and migration of underwater fishes, but also passages for shipping passing ships on water.

Blocking of migration and migration channels of underwater fishes damages an original underwater ecosystem of a river, and reduces the population of underwater migration organisms. With the national emphasis on environmental protection and the enhancement of national environmental protection consciousness, various fish remedial measures are applied to engineering practice, and the measures mainly taken at present are divided into three categories: firstly, artificial propagation releasing is carried out; secondly, building an artificial simulated spawning site in the river channel; and thirdly, building fish passing facilities which mainly comprise fishways, fish gates, fish lifts, fish gathering and transporting ships and the like. Although the existing fish remedial measures have certain effects, the existing fish remedial measures also have respective defects. The two measures of artificial propagation and releasing and artificial simulated spawning ground construction in the river channel have certain effects proved by practice, but the effects are not obvious, and the problem of reduction of the diversity of fish populations in the river basin is caused. The fishway engineering is generally suitable for medium and small water head river-blocking buildings to pass fishes, but the investment cost is higher in the early stage of construction, the operation management cost is higher after the construction, and the design difficulty is higher; the fish gate and the fish elevator are suitable for passing fish in a high-water-head river-blocking building, but the number of electromechanical control equipment is large, the operation management and maintenance cost is high, and the fish passing process is not continuous; the fish collecting ship has the problems of noise, water environment pollution, discontinuous fish dam-crossing process and the like.

Aiming at the problem of blocking an overwater shipping channel, the main measures adopted at present are to construct a navigation building, the navigation building is mainly divided into a ship lock and a ship lift, and the ship lock is most widely applied. In the actual construction of engineering, the ship lock is an essential important component in a river-blocking building, is also a water flow channel for communicating the upstream and downstream of the river-blocking building, has a large communicated water body, allows the upstream and downstream fishes of the river-blocking building to freely pass to a certain extent, and has a certain bidirectional passing potential. At present, the ship lock design only considers the requirement of navigation, and the potential of the ship lock capable of passing the fish is not fully developed. If the ship lock is improved or some fish luring and driving devices are added, fish passing through the ship lock can be realized.

According to the existing research data, the current research on the ship lock fish passing technology and research results are many, but the research is mainly focused on inducing the fishes into the lock chamber and driving the fishes to the upstream of the river blocking building, and the problem that the fishes migrate from the upstream of the river blocking building to the downstream is ignored. The migratory fishes only can flow down along the water potential through the drainage channel due to no special fish passing channel when passing through the river-blocking building. Because the difference between the water levels upstream and downstream of the river-blocking building is large, the huge energy generated during water drainage can damage the fishes and even lead the death of the fishes.

At present, news of fish injury and death caused by flood discharge of river-blocking buildings is commonly reported. Therefore, when the fish facility is built, not only is the fish to be sent from the downstream to the upstream, but also the fish is safely returned from the upstream to the downstream, so that the ecological influence caused by building a river-blocking building can be really reduced, and the aim of harmonious connection between people and nature is fulfilled.

4. closing the upstream gate 3, closing the fish luring lamps 9, opening the downstream water conveying gallery gate 18, draining water downstream from the chamber 4, starting the rotating shaft 13 at the same time, rotating the fish luring lamps 9 outside the chamber wall 5 into the wall, and rotating the fish driving lamps 9 inside the chamber wall 5 out of the wall;

5. when the water level in the lock chamber 4 and the water level at the downstream reach a reasonable height difference (the reasonable height difference means that the fishes are driven to the downstream by means of the water level difference at the upstream and the downstream, the energy generated by the water level difference cannot damage the fishes, and the water level difference is the reasonable height difference), closing the downstream water delivery gallery gate 18, opening the downstream gate 6 of the ship lock, and flushing the fishes in the lock chamber 4 to the downstream by means of the water potential;

6. starting the rotating shaft 13, rotating the fish luring lamp 9 in the downstream navigation wall 1 out of the wall body, opening the fish luring lamp 9 on the downstream navigation wall 1 to lure fishes to the downstream, simultaneously opening the fish driving lamp 10 in the lock chamber 4 and the fish driving lamp 10 at the side of the lock chamber 4 of the upstream gate 6, and driving the residual fishes in the lock chamber 4 out of the lock chamber 4, so as to ensure the thoroughness of the fishes;

7. closing the downstream gate 6, closing the fish-driving lamp 10 in the gate chamber 4, closing the fish-luring lamp 9 on the downstream navigation wall 1, opening the fish-driving lamp 10 on the downstream side of the downstream gate 6, and driving the fish away from the front of the downstream gate 6;

8. and starting the rotating shaft 13, and rotating all the fish luring lamps 9 and the fish driving lamps 10 which are arranged outside the wall body into the wall body to complete the fish passing process from the upstream to the downstream.

And thirdly, when the ship lock is under the condition that no ship navigates, the ship lock can open the upstream gate and the downstream gate to drain water downstream, and assist the river-blocking building to drain water downstream, so that the function of the water lock is achieved.

And fourthly, when the ship lock is a multi-stage ship lock, the arrangement of the lock chamber and the lock head of the ship lock is unchanged, the arrangement of the upstream navigation wall of the uppermost ship lock and the arrangement of the downstream navigation wall of the lowest ship lock are also unchanged, the upstream gate of the next ship lock is equal to the downstream gate of the previous ship lock, and the steps are repeated.

The invention has been described in considerable detail by way of illustration and example only, and is not to be construed as limited thereto, since various modifications and changes may be made without departing from the spirit and scope of the invention as defined in the appended claims.
