Abstract
Description
Technical Field
[0001] The utility model relates to a surface water intake device for an inclined culvert and a horizontal pipe, belonging to the technical field of hydraulic structures. Background Art
[0002] In the urban and rural water supply systems in our country, reservoirs are the main water supply sources. To achieve the water intake function of the reservoir, the water supply pipe is usually directly connected into the reservoir. According to the water intake depth, the reservoir water intake methods are mainly divided into two types: deep water intake and surface water intake. In the deep water intake method, since the water temperature in the reservoir gradually decreases with the increase of the reservoir water level, the taken-out water has a lower temperature. When the low-temperature water is used for agricultural irrigation, it may have an adverse impact on the growth of crops. At the same time, the low-temperature discharged water will also have a negative impact on the downstream ecological environment, such as affecting the survival and reproduction of aquatic organisms. On the other hand, in deep water intake, as the reservoir water level deepens, the turbidity of the water body will also gradually increase. The increase in turbidity often leads to an increase in impurities in the water, thereby affecting the clarity of the water quality. More seriously, the increase in turbidity may also cause the olfactory threshold concentration to exceed the standard, that is, the content of odor substances in the water exceeds the perception threshold of people, thus affecting the sensory property index of the water body and causing the water quality to decline. To solve the above problems, the utility model proposes a surface water intake device for an inclined culvert and a horizontal pipe. The utility model has the characteristics of stable structure, simple operation, economy and practicability. By taking water from the surface layer of the reservoir, it can effectively reduce the water temperature fluctuation and reduce the negative impact on the natural environment and ecosystem. At the same time, the water supply quality is optimized, ensuring the stable and reliable water supply service. Content of the Utility Model
[0003] The purpose of the utility model is to provide a surface water intake device for an inclined culvert and a horizontal pipe to solve the problems put forward in the above background art.
[0004] To achieve the above object, the present utility model provides the following technical solution: An inclined culvert horizontal pipe surface water intake device, characterized in that it includes an inclined culvert horizontal pipe (1), a T-shaped fork pipe (2), a valve (3), an air supply pipe (4), a connecting pipe (5), an extension pipe (6), a trash rack (7), a valve stem (8), an extended valve stem (9), an opening and closing handwheel (10), an opening and closing platform (11), and a pre-embedded sleeve (12); the inclined culvert horizontal pipe (1) is a metal pipe, one upper end of the inclined culvert horizontal pipe (1) is connected to the air supply pipe (4), the other end of the inclined culvert horizontal pipe (1) below the water surface line is connected to the connecting pipe (5), a T-shaped fork pipe (2) is arranged outside the inclined culvert horizontal pipe (1), the installation direction of the T-shaped fork pipe (2) is horizontal, the T-shaped fork pipe (2) is connected to the valve (3), the valve (3) is connected to the extension pipe (6), a trash rack (7) is arranged at the end of the extension pipe (6), an extended valve stem (9) is arranged at the top of the valve stem (8), an opening and closing handwheel (10) is arranged at the top of the extended valve stem (9), the extended valve stem (9) passes through the pre-embedded sleeve (12), and the pre-embedded sleeve (12) is embedded in the opening and closing platform (11).
[0005] The inclined culvert horizontal pipe (1) is arranged along the reservoir bank slope, and the shape of the air supply pipe (4) is a vertical 180° elbow.
[0006] The materials used for the inclined culvert horizontal pipe (1), T-shaped fork pipe (2), air supply pipe (4), connecting pipe (5), and extension pipe (6) are 20 seamless steel pipes, the materials used for the valve stem (8) and extended valve stem (9) are 20Cr13 stainless steel, and the material used for the opening and closing handwheel (10) is HT200 malleable iron.
[0007] The inclined culvert horizontal pipe (1), T-shaped fork pipe (2), air supply pipe (4), and connecting pipe (5) are installed by flange bolt connection, the T-shaped fork pipe (2), valve (3), extension pipe (6), and trash rack (7) are installed by flange bolt connection, the valve stem (8) and the extended valve stem (9) are installed in a hinged fixed mode, and the extended valve stem (9) and the opening and closing handwheel (10) are installed by bolt connection.
[0008] The working principle of the present utility model is as follows: The core components of the present utility model, namely the inclined culvert horizontal pipe (1), T-shaped fork pipe (2), valve (3), air supply pipe (4), connecting pipe (5), extension pipe (6), and trash rack (7), are all assembled by flange bolt connection technology. The inclined culvert horizontal pipe (1) is formed by flange bolt connection or welding according to its length. The T-shaped fork pipe (2) is formed by cutting the raw material and then cold bending or hot bending it to form the preliminary shape of the fork pipe and then welding it, ensuring the stability, sealing performance, and long-term operation reliability of the entire system. An articulated fixing mode is adopted between the valve stem (8) and the extended valve stem (9), which not only improves the transmission efficiency but also ensures the stability of operation. The extended valve stem (9) and the opening and closing handwheel (10) are tightly connected by bolts, enabling the operator to easily and accurately control the valve on the opening and closing platform (11). During the actual operation process, the operator stands on the opening and closing platform (11) and continuously rotates the opening and closing handwheel (10), using an efficient mechanical transmission mechanism to achieve precise control of the opening and closing of the valve (3). During this process, the valve stem (8) and the extended valve stem (9) rotate coaxially and synchronously to drive the valve to move up and down. As the water level of the reservoir gradually decreases, the opening and closing platform (11) at the lower water level gradually emerges above the water surface. At this time, as the water level continues to drop, the valves designed at the low water level will be opened one by one after manual confirmation to adapt to the water level change and maintain the continuity of water intake. In addition, according to the order preset according to the terrain and layout of the reservoir bank, the operator will open one by one the remaining valves that are gradually exposed due to the water level drop. Conversely, when the water level of the reservoir rises, the operator needs to operate in reverse order, from the low water level to the high water level, to close the valves on the opening and closing platform (11) that are about to be submerged by water. During this process, the water intake task originally borne by the low water level valves will smoothly transition to the valves at the higher water level, ensuring the continuity and efficiency of water intake. That is, when the opening and closing platform (11) of the low water level valves is about to be covered by water, the operator quickly and orderly closes these valves and simultaneously opens the valves at a higher water level to take over the water intake task, thereby realizing the opening and closing of surface water intake from the reservoir.
[0009] The beneficial effects of the present utility model are as follows: The present utility model has the advantages of stable structure, simple operation, and economic practicality. Through the designed water intake method, it can take water from the surface layer of the reservoir, effectively avoiding pollution and turbidity problems, and ensuring the purity and safety of water quality. At the same time, its simple opening and closing operation reduces the usage threshold and improves work efficiency. In addition, this device is economic and practical, reducing energy consumption and maintenance costs, and promoting the efficient utilization and protection of water resources.

[0016] Embodiment 1: As Figures 1 to 3As shown in the figure, an inclined culvert horizontal pipe surface water intake device includes an inclined culvert horizontal pipe (1), a T-shaped fork pipe (2), a valve (3), an air supply pipe (4), a connecting pipe (5), an extension pipe (6), a trash rack (7), a valve rod (8), an extended valve rod (9), an opening and closing handwheel (10), an opening and closing platform (11), and a pre-buried sleeve (12); the inclined culvert horizontal pipe (1) is a metal pipe, one upper end of the inclined culvert horizontal pipe (1) is connected to the air supply pipe (4), the other end of the inclined culvert horizontal pipe (1) below the water surface line is connected to the connecting pipe (5), a T-shaped fork pipe (2) is arranged outside the inclined culvert horizontal pipe (1), the installation direction of the T-shaped fork pipe (2) is horizontal, the T-shaped fork pipe (2) is connected to the valve (3), the valve (3) is connected to the extension pipe (6), a trash rack (7) is arranged at the end of the extension pipe (6), an extended valve rod (9) is arranged at the top of the valve rod (8), an opening and closing handwheel (10) is arranged at the top of the extended valve rod (9), the extended valve rod (9) passes through the pre-buried sleeve (12), and the pre-buried sleeve (12) is buried in the opening and closing platform (11).
[0017] As Figures 1 to 3 shown, the inclined culvert horizontal pipe (1) is arranged along the reservoir bank slope, and the shape of the air supply pipe (4) is a vertical 180° elbow. This design can not only effectively solve the air supply problem during the water supply process, ensure smooth water flow, but also significantly enhance the ability to resist foreign object blockage.
