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 figure 1, the embodiment of the utility model discloses an automatic carry hydraulic means who crosses 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 of a pipeline type structure, and the water channel 1 can be made of steel pipes or can be formed by pouring reinforced concrete. As can be seen from fig. 1, the top of the channel 1 is below the upstream water level of the dam, so that water located upstream can automatically flow into the channel 1. The arrows in fig. 1 show the obliquely downward flow direction of the water in the water course 1. A water outlet 12 is arranged below the water channel, and a gate 11 capable of opening and closing the water outlet 12 is arranged at the water outlet 12. The shutter 11 may be driven by an actuator such as a hydraulic cylinder.

The collecting mechanism comprises a groove 4 and an inclined platform 5 which are arranged at the lower end of the water channel 1. After entering the groove 4, water in the water channel 1 can flow from the ramp 5 to the downstream of the dam through the water outlet 12 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 conveying mechanism comprises an air storage bottle 2, a piston 41 and an air pump 6. The air pump 6 is used for supplying air to the air storage bottle 2. An air supply pipe 3 is connected between the air storage cylinder 2 and the groove 4. Be equipped with valve 21 on air supply pipe 3, piston 41 movably set up in recess 4, this piston can be rubber buffer or polyurethane plastic stopper to can further pack metal material such as carbon steel, stainless steel in its inside with increase structural strength. When the gate 11 is closed and the valve 21 is opened, air in the gas storage cylinder 2 can enter the groove 4, the piston 41 is pushed to enter the water channel 1 from the groove 4 and move upwards, and fish gathered in the groove 4 is conveyed to the upstream of the dam.

The utility model discloses an automatic carry water conservancy device of crossing dam when using, at first open gate 11, the water on dam upper reaches flows from water course 1 downwards, and these water reachs recess 4 after, from the 12 flow direction sloping platforms 5 of delivery port above recess 4 again, forms induced rivers on sloping platforms 5. Fish downstream of the dam enters the trough 4 upstream along the induced water flow. In addition, the gas 6 can fill the gas cylinder 2 with air during operation. When a certain amount of fish is gathered in the groove 4, the valve 21 is opened, the gate 11 is closed, the air in the gas storage cylinder 2 enters the groove 4, the piston 41 is pushed to move upwards, an upward flowing water flow is formed in the water channel 1, the water flow flushes the fish in the groove 4 out of the water channel 1, and the fish shoal turns over the dam to reach the upstream of the dam. When the piston 41 reaches the vicinity of the inlet of the waterway 1, the shutter 11 is opened again, and the piston 41 falls back into the recess 4 again due to the gravity and the water pressure.

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.
