Description

Technical Field

[0001] The invention relates to the technical field of fish fry placement, and in particular to a system and method for releasing fish catch or fish fry in a high-bank and large-drop scenario. Background Art

[0002] Fish releasing activities are widely used in aquaculture operations such as the transfer of fish fry, fish fingerlings and broodstock into ponds, artificial aquaculture release and fish collection and transportation across dams. The most typical methods include traditional adaptive surface release with filled bags and slide-in-water release.

[0003] Collecting and transporting fish and releasing them across the dam is one of the ecological compensation methods for hydropower stations or reservoir dams. The collected fish are divided into two categories: those that must cross the dam and those that do not have to cross the dam. The release of the two types of fish is not only one of the basic links of collection and transportation, but also includes releasing them across the dam to suitable river sections and releasing them in the original river sections. At present, the former mainly uses special fishing boats to release fish. The fish are released from the release port near the bottom of the boat. The release port valve can only be opened on the computer, and the fish can be seen swimming out with the water on the monitoring image.

[0004] The river section below the hydropower station dam is mostly a deep U-shaped river valley. Due to the changes in working conditions and seasons, especially the water conditions or flood discharge during the flood season, the water level and even the elevation of the riverbed change significantly. The traditional artificial or special fish transport boats have serious safety hazards. The buried discharge pipe project is extremely difficult and threatens the safety of the river bank. It cannot adapt to the drastic changes in the water level and riverbed below the dam at any time and with the season. After completion, the discharge pipe is usually very long and the distance drop is huge. Such discharge is tantamount to high-altitude throwing, and it is impossible to achieve gentle discharge on the water surface. In particular, the water level changes significantly at any time, and it is difficult to ensure that the fish outlet is in the water near the water surface. The fish outlet may also be buried deep due to the rise of the riverbed during the flood season, which is difficult to maintain. For this reason, a high-bank large drop discharge system was conceived and designed, which can be used for the release of fish catches or the release of fish fry. Summary of the invention

[0025] The fry are transported to the release pond 1 by a fish transport vehicle, and the release component 4 is lifted to one side of the bottom discharge port of the release chute 2 by the lifting component 3 with the fry in the release pond 1, so that the top opening of the release component 4 is connected with the bottom discharge port of the release chute 2, and then the fry in the release pond 1 are slid into the release component 4 through the release chute 2. After there are enough fry in the release component 4, the lifting component 3 is controlled to lower the release component 4 to the fish collecting pond 5. After the release component 4 arrives at the fish collecting pond 5, the release component 4 is controlled to release the fry in the tank, and finally the release component 4 is lifted by the lifting component 3.

[0026] like Figure 2-4 The discharge assembly 4 comprises a cylindrical tank body 401 at the top, a fish placing bucket 402 coaxially connected to the bottom of the tank body 401, and a support column 403 vertically fixed to the bottom of the tank body 401. A bottom plate 413 is provided at the bottom end of the fish placing bucket 402, a notch is provided on the bottom plate 413, a discharge plate 414 is rotatably provided on the bottom plate 413 to cover the notch, and the output end of the driving member is connected to the mounting shaft 412 of the discharge plate 414.

[0027] A circular opening is arranged on the top of the tank body 401, and the opening on the top of the tank body 401 is used for entering fish and water; the support column 403 is used for providing stable support for the tank body 401 when the tank body 401 is placed on the ground; the discharge plate 414 is used for covering the gap on the bottom plate 413; the discharge plate 414 is rotated by a driving member, and the discharge plate 414 is rotated to the other side of the gap on the bottom plate 413, so that the gap on the bottom plate 413 is opened, and the inside of the tank body 401 is connected to the external water body through the gap; then, by lifting the tank body 401, the fry and water in the tank body 401 flow out from the gap on the bottom plate 413 under the action of gravity, thereby realizing discharge.

The discharge motor 408 drives the driving gear 409 to rotate, and the driving gear 409 drives the driven gear 410 meshing with it to rotate. Since the driven gear 410 is coaxially fixed on the mounting shaft 412 of the discharge plate 414, the rotation of the discharge plate 414 can be realized.

[0031] like Figure 3 As shown, in order to ensure the stable support of the tank body 401 by the support structure at the bottom of the bottom tank body 401, an oblique support rod 411 is arranged between the support bottom ring 404 and the fish placing bucket 402, and the support column 403 and the oblique support rod 411 are arranged at equal angles around the axis of the tank body 401.
