Background

In the construction of hydraulic engineering, dams are often built on rivers to block water. After the construction of the river, the dams can influence the migration and spawning of fishes in the river, and possibly lead to the extinction of precious special fish species. In order to ensure the normal breeding requirement of the fishes, the engineering personnel set a fishway on the dam, water flow flows from the upstream to the downstream of the dam in the fishway, a multi-stage step-shaped structure is arranged in the fishway, and the fishes have the life habit of going up in a counter-current way, so that the fishes can jump up on the steps step by step against the water flow to reach the upstream of the dam. The existing fishway needs fishes to overcome the impact force of water flow by means of self-strength and jump upwards step by step continuously to cross over the dam, which is a difficult challenge for fishes with small body sizes and weak physical strength, and some kinds of fishes can not cross over the dam through the existing fishway to reach a target spawning site due to the body sizes and the physical strength.

Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their detailed description will be omitted.

As shown in FIG. 1 and FIG. 2, the embodiment of the present invention discloses a water conservancy device capable of automatically conveying water through a dam. The water conservancy device can enable fishes which are slept to lay eggs to pass through the dam from the downstream of the dam and then reach the upstream of the dam. The water conservancy device capable of automatically conveying across the dam comprises an inclined water channel 1 arranged on a dam body of the dam, a conveying mechanism and a collecting mechanism.

The water channel 1 is obliquely arranged on the back surface of the dam body, and the water channel 1 is used for enabling water at the upstream of the dam to flow to the downstream. The water channel 1 is an inclined long groove structure formed by a bottom wall and side walls positioned at two sides of the bottom wall, and only the bottom wall of the water channel 1 is shown in fig. 1. As can be seen from fig. 1, the bottom wall of the top of the waterway 1 is lower than the upstream water level of the dam, so that water located upstream can automatically flow into the waterway 1. A plurality of convex energy dissipation lugs 11 can be further arranged in the water channel 1 to buffer water flow and slow down the downward flow speed of the water flow in the water channel 1. The arrows in fig. 1 show the obliquely downward flow direction of the water in the water course 1.

The conveying mechanism comprises a rotatable main shaft 2 which is arranged in the water channel 1 and is obliquely arranged and an outer barrel 3 which is coaxially sleeved on the main shaft 2, a spiral partition plate 31 surrounding the main shaft 2 is arranged between the main shaft 2 and the outer barrel 3, a plurality of water storage areas 32 are enclosed between the outer barrel 3 and the spiral partition plate 31, and the top end of the conveying mechanism is higher than the upstream water level of the dam.

The collecting mechanism comprises a groove 4 and an inclined platform 5 which are arranged at the lower end of the water channel. After entering the groove 4, the water in the water channel 1 can flow to the downstream of the dam from the sloping platform 5 to form induced water flow. The top of the ramp 5 is above the downstream water level of the dam. When the fishes meet the induced water flow flowing down on the sloping platform 5, the fishes enter the groove 4 along the sloping platform 5 and gradually gather in the groove 4 due to the upstream habit of the fishes.

The main shaft 2 can be fixed in the water channel 1 through a support and other existing mechanisms and is driven to rotate by a motor, a diesel engine and other common power devices. Since the main shaft 2 is inclined, water can be stably stored in the water storage area 32 having a substantially triangular cross section surrounded by the spiral partition 31 and the outer cylinder 3. When the spindle 2 rotates, the lower end of the spiral partition 32 scoops up a part of the water from the groove 4 to the water storage area 32, and the water in the water storage area 32 is continuously conveyed upwards by the spiral partition 31 until reaching the upstream of the dam and then flows out of the water storage area 32. Fish carried in the water will also be transported upstream of the dam. As the main shaft 2 continues to rotate, a substantial portion of the fish in the trough 4 can be captured in the holding area 32 and transported past the dam.

As shown in fig. 1, a movable baffle 12 may be further disposed at the upper portion of the waterway 1, the baffle 12 is perpendicular to the side wall of the waterway 1, the lower end of the baffle 12 is hinged to the waterway 1, and the upper end of the baffle 12 may swing up and down around the hinged point of the lower end. When the upstream water level of the dam is higher, the baffle plate 12 can be driven by a lifting rope or a hydraulic cylinder to lift upwards, and the water quantity of the water channel 1 is reduced. When the upstream water level of the dam is lower, the baffle plate 12 can be driven by a lifting rope or a hydraulic cylinder to rotate downwards, the water quantity of the water channel 1 is properly increased, and the water quantity in the water channel 1 can be kept moderate no matter how the water level changes.

To sum up, the utility model discloses an automatic water conservancy device who carries across dam can assemble fish earlier, and rethread mechanical mechanism passes the dam with fish automatic conveying, has avoided fish to rely on self strength to overturn the not enough scheduling problem of physical power that the dam met, has protected various fishes in the river can normally the migration lay eggs effectively.

Exemplary embodiments of the present invention have been particularly shown and described above. It is to be understood that the invention is not to be limited to the disclosed embodiments, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
