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 conveying belt 2 arranged in the water channel 1 and a bucket 3 arranged on the conveying belt 2, wherein the top end of the conveying belt 2 is higher than the upstream water level of the dam, and when the conveying belt 2 operates, the bucket 3 can be driven to be at the height above the upstream water level.
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.
In this embodiment, recess 4 is the circular arc groove, and when conveyer belt 2 during operation, can drive the motion of bucket 3, when bucket 3 moves to in the recess 4, can dig water in the recess 4, dig the fish that assembles in recess 4 with the water in the recess 4, when bucket 3 moves to the top position of conveyer belt 2, this bucket 3 is reversed, carries the upstream to the dam with fish and the water in the bucket 3. In the present embodiment, 1 bucket 3 is provided. The bucket 3 can be provided in a plurality of numbers to improve the fish digging efficiency. As can be seen from fig. 2, a plurality of drain holes 31 are provided at an end of the bucket 3 remote from the conveyor belt 2, and these drain holes can drain excess water in the upper portion of the bucket 3, but can prevent fish from escaping, so that the weight of the water in the bucket 3 can be reduced, and the work load of the conveyor belt 2 can be reduced.
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.
