Description

Technical Field

[0001] The present invention relates to the technical field of fish passage facilities, and in particular to a movable, high-efficiency upstream-assisting fish passage device and an operating method thereof. Background Art

[0002] While the construction of current water conservancy projects has significantly benefited people's livelihoods, it has also had a serious impact on fish habitats and normal living habits. Many fish species have experienced habitat destruction and reduced living space, leading to a sharp decline in populations. Some fish are unable to migrate and maintain their normal living habits due to water conservancy projects, resulting in the inability of fish populations to continue to reproduce. Therefore, protecting fish habitats and helping them complete their normal living habits are currently important issues that cannot be ignored.

[0003] Numerous devices have been invented to aid fish migration, including vertical slot fishways, Daniel fishways, and combined fishways. Unfortunately, the slow natural upward migration of fish within these fishways affects their efficiency. Most current fishways fail to account for the weak migratory abilities of some fish, making them difficult to navigate or inefficient. Furthermore, some fish may become trapped in the pool for various reasons, significantly impacting the passage efficiency. The plight of these fish deserves our attention and solutions. Summary of the Invention

[0004] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide a movable, efficient upstream fish passage device and operation method. This fishway can ensure the migration needs of normal migratory fish while assisting some fish with weak migratory ability and trapped in the pool chamber to pass efficiently.

[0005] In order to realize the above-mentioned technical features, the purpose of the present invention is realized as follows: a movable and efficient upstream fish-passing device, including a vertical slot fish-passing system, a stranded fish identification system and an intelligent transfer system, wherein the vertical slot fish-passing system, the stranded fish identification system and the intelligent transfer system are provided with a transfer gantry and a vertical slot fishway.

The transfer fish box is provided with a switch door, and a ring is provided on the switch door, which is connected to a first rope and controlled by a first crane. The first crane moves on a first slide rail; a ring is provided on the transfer fish box, which is connected to a first rope and controlled by a second crane. The second crane also moves on the first slide rail. A small door is provided on the rear side of the transfer fish box, which is controlled by a first rotating shaft and opens to a second water filter net.

[0007] Preferably, the second crane is provided with four small pulleys for easy movement on the first slide rail, the second crane is provided with two first motors to control the first rope, a groove is provided in the middle of the first motor to control the length of the first rope, and a hook is provided at the end of the first rope for connecting to the ring on the transfer fish box.

[0008] Preferably, a fish-driving corridor is provided in the transfer gantry, and the overall movement of the fish-driving corridor is controlled by two longitudinal slide rails and one transverse slide rail. Two third cranes are provided under the two longitudinal slide rails, and second ropes are connected to the third cranes. The two second ropes are connected to the transverse slide rails. The main structure of the fish-driving corridor is a wire mesh, and the second rotating shaft is on both sides.

[0010] Preferably, a pulley assembly is provided under the transfer gantry, with a total of four pulleys, two pulleys on each side of the transfer gantry, all of which slide on the second slide rail on the vertical slot fishway.

[0011] Preferably, the transfer gantry is provided with two first high-definition probes, which are responsible for monitoring and real-time analysis of the working status to ensure the normal and orderly operation of the transfer gantry.

[0013] Another aspect of the present invention provides a method for operating a movable, efficient, upstream-assisted fish-passing device, comprising the following steps: S1. The entire device operates under the monitoring of a second high-definition probe in the vertical slot fishway chamber. When the second high-definition probe detects that the number of fish trapped in the chamber exceeds a certain number, the transfer gantry begins to move to the designated chamber. At this time, the first baffle connected to the third rope slowly descends under the control of the second motor. The first baffle is connected to the second and third baffles on both sides, respectively, to block the fish upstream and downstream of the chamber. S2, then the rotating arm drives the third rope to rotate toward both sides of the transfer gantry under the control of the third motor, so as to facilitate the normal operation of the fish driving gantry; S3. After the rotating arm rotates to the designated position, the fish driving chariot connected to the second rope slowly descends to the bottom under the control of two third cranes. Then, the fish driving chariot moves longitudinally under the control of the third cranes to gradually gather the fish in the tank chamber. At the same time, two fourth motors located in the transverse slide rails control the operation of the second rotating shafts on both sides under the recognition of the first high-definition probe, ensuring that the second rotating shafts on both sides of the fish driving chariot always stay close to the walls of the tank chamber until they reach the designated position during the fish driving process.

Then the second crane controls the opening and closing door of the fish transfer box to rise, leaving enough space for the fish to enter. S5: The fish driving cradle slowly rises under the control of the third crane and continues to move longitudinally to the side of the wall. Then, it slowly descends under the control of the third crane and pushes the fish into the transfer fish box. The transfer fish box door is then closed under the control of the second crane, and water flows into the box through the second water filter on both sides of the transfer fish box. S4: The fish transfer box rises to the top under the control of the second crane and the first crane, then the fish driving scuttle rises to its original position under the control of the third crane, and finally the first baffle rises to its original position under the control of the third motor, and the transfer gantry begins to move upstream along the second slide rail; S5. After the transfer gantry reaches the upstream, the second crane and the first crane control the transfer fish box to descend into the water. Then, the small door at the rear side of the transfer fish box rotates and opens under the control of the first rotating shaft. The water flows through the box through the second water filter net. The second crane controls the switch door to open. The fish in the box swim out of the box driven by the water flow, and the transfer is successfully completed.

[0014] Preferably, it also includes S6: the second crane controls the switch door to close, and then the first crane and the second crane jointly control the transfer fish box to rise and move longitudinally to the original position, waiting for the second high-definition probe to identify the pond room with retained fish again, and then the next round of transfer can be started.
