Problems solved by technology

This prior art uses an air compression device to lift the water within a certain distance from the downstream of the river to the upstream of the river by laying PVC pipes on the water surface, resulting in local internal circulation of the water.
However, because the diameter of the pipeline in this device is usually small (300mm), and the existence of the trachea and the elbow makes the space for aquatic organisms to move in the channel smaller, so there are two different water ecology before and after the power is lifted in the existing technology.

Embodiment 1

[0054] A kind of water bladder type water dynamic ecological lifting device provided in this embodiment, such as figure 1 shown, said

[0055] A water bladder type water dynamic ecological lifting device, including a deformable water bladder 1;

[0056] The water bag housing 2 with the top open;

[0057] The water inlet automatic flashboard 3 arranged on any side of the lower part of the water bag shell is used to realize the batch order water intake of the water bag type water dynamic ecological lifting device; the deformable water bag 1 is arranged on the water bag In the shell 2, and form a semi-closed system with the water bag shell 2;

[0058] The upper end of the water bag shell 2 is provided with a water outlet, so that the end water flows into the downstream channel;

[0059] The water bag casing 2 and the water outlet are all higher than the water level of the downstream river, so as to ensure that the downstream water outlet does not return, and the high-level riv...

Embodiment 2

[0071] (1) Use the device of the present invention to improve the water quality of a certain river in Shandong.

[0072] The main parameters are as follows: the width of the upstream channel is 30m, the water depth is 2m, the lifting height is 5m, and the lifting water volume is 10000m 3 / h; the width of the downstream channel is 30m, and the water depth is 2m; the largest organism in the water body is considered as 0.5m×1m×2m. The size of the water bag shell is 12m×15m×15m, and the size of the deformable water bag is 10m×13m×14m. The design single maximum water inflow is 400m 3 , the biological channel volume is 250m 3 , the cavity volume is 700m 3 , the single action time is 2.5 minutes, and the total lift is 10000m 3 / h. The design water volume of the pump is 16250m 3 / h, head is 8.5m. The opening size of the water inlet automatic gate is 1m×1.5m, which can satisfy the largest organisms to enter the downstream high-water level river through the lifting device without...

Abstract

The invention discloses a water bag type water power ecological lifting device and application thereof and belongs to the technical field of water environment treatment and ecological protection. The water bag type water power ecological lifting device comprises a deformable water bag, a water bag with the open top, and an automatic water inlet gate plate arranged on any side face of the lower portion of the water bag shell, so that batch sequence water inflowing of the water bag type water power ecological lifting device is achieved. The deformable water bag is arranged in the water bag shell, and the deformable water bag and the water bag shell form a semi-closed system. A water outlet is formed in the upper end of the water bag shell so that water flowing out of the tail end can flow into a downstream river course. The water bag shell and the water outlet are both higher than the water level of the downstream river course so that water flowing out the downstream river course cannot flow back. The water bag type water power ecological lifting device is particularly suitable for small-lift and high-flow power water lifting of medium and small-scale river courses / canals with high requirements for a water ecological system without influencing the living state of aquatic organisms in water.

Description

technical field [0001] The invention relates to the technical fields of water environment treatment and ecological protection, in particular to a water bladder type water dynamic ecological lifting device and its application. Background technique [0002] With the rapid development of my country's economy and the acceleration of industrialization and urbanization, the demand for water resources is increasing rapidly. In order to meet the needs of irrigation and landscape, a large number of pumping stations have been built in small and medium-sized rivers and canals to raise the water level. [0003] When conventional water pumps are used for water conservancy lifting, the impeller speed in the pump is very high (up to 2900 rpm or 1450 rpm), and the linear speed of the impeller is also very high, which is very destructive to organisms in the water body; at the same time, The narrow cavity inside the water pump also restricts the passage of aquatic organisms such as large fis...
