Description

Technical Field

[0001] This utility model relates to the field of water conservation technology in water conservancy construction, specifically a water conservation device for water conservancy construction. Background Technology

[0002] In water conservancy construction, throttling devices are used to control flow rate, regulate water flow velocity, reduce water flow pressure, or adjust water flow direction. Throttling devices are commonly used in various stages of water conservancy projects, such as dam construction, irrigation systems, drainage systems, and hydropower generation. Their function is to control water flow by adjusting the flow state of the fluid.

[0003] For example, a water conservancy construction flow-saving device, as disclosed in announcement number CN221919178U, includes a water conservancy pipeline. A regulating valve body is fixedly connected to the input side of the water conservancy pipeline. A receiving pipe is fixedly connected to the top of the water conservancy pipeline near the regulating valve body. The receiving pipe is inclined away from the regulating valve body. A filter cylinder is detachably fixedly connected inside the receiving pipe. The bottom of the filter cylinder has a sloping opening corresponding to the cross-section of the inner wall of the water conservancy pipeline. Several filter holes are formed at the bottom of the filter cylinder, their positions corresponding to the positions inside the water conservancy pipeline. The advantages of this invention are: by filtering impurities in the water through the filter cylinder, and the inclined filter cylinder, intercepted debris is flushed to the upper part of the filter cylinder, and then the impeller rotation carries the impurities into the interior of the elastic interception plate, achieving collection of impurities, preventing impurities from remaining on the filter holes, and reducing the impact on the water flow.

[0004] The aforementioned patent proposes that impurities can be carried into the interior of the elastic interception plate by rotating the auger, thereby collecting the impurities. However, during the use of the water-saving device in water conservancy construction, the water flows inside the water conservancy pipeline. In extreme weather, the temperature is too low, which can easily cause the water to freeze, resulting in water flow interruption. This affects the stability of the overall water flow and is not conducive to the normal use of the water-saving device.

[0005] Therefore, we propose a water-saving device for water conservancy construction to solve the problems mentioned above. Utility Model Content

Mounting blocks are installed at both the upper and lower ends of both protective rings A and B, with bolts for fixing on one side of each mounting block. The mounting blocks and bolts secure the protective rings A and B to the outside of the water-saving pipe, and the antifreeze covers and antifreeze layer provide antifreeze protection, enabling the water-saving pipe to withstand low temperatures.
