Abstract
Description
Technical Field
[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a water distribution structure for small irrigation channels. Background Technology
[0002] To date, while existing sluice gates in water conservancy channels have achieved the function of controlling water levels and regulating water flow to a certain extent, most sluice gates can only open to release water and cannot be fully opened. For small irrigation channels, the operation of existing sluice gates is inconvenient and costly, and they are prone to uneven water intake and seepage problems after years of operation. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model aims to provide a water distribution structure for small irrigation channels. This solution allows for convenient operation in small irrigation channels, free control of water intake, and effective prevention of seepage.
[0004] This utility model is achieved through the following technical solution: A water distribution structure for small irrigation channels, comprising: The main channel has a branch outlet on one side, and the top of the branch outlet is open. A lightweight gate is provided at the water distribution outlet, and an operating platform is provided on the top of the water distribution outlet; The water outlet has a slot on its periphery for the lightweight gate to be inserted. The downstream side and bottom of the slot are covered with rubber seals. The lightweight gate can squeeze the rubber seals to close the water outlet.
[0005] Compared to existing technologies, the operation of existing gates for small irrigation channels is inconvenient and costly, and they are prone to uneven water intake and seepage after years of operation. This utility model provides a water distribution structure for small irrigation channels. Using this solution, it is easy to operate in small irrigation channels, the water intake can be freely controlled, and seepage can be effectively prevented. The specific design includes a main channel and a branch outlet on one side of the main channel, connected to the downstream channel. A lightweight gate is installed at the branch outlet, with an operating platform on top. When water needs to be diverted, a person simply stands on the operating platform and lifts the lightweight gate upwards. Through manual control, the entire gate can be lifted upwards as a whole, allowing the operator to judge the lifting height and control the water flow. The operation is quick and the cost is extremely low for small irrigation channels. Secondly, slots are provided around the branch outlet, with rubber seals on the downstream side and bottom of the slots. Under the weight of the lightweight gate itself and the thrust of water from the upstream channel, the lightweight gate compresses the rubber seals, achieving water stoppage and effectively preventing seepage. Furthermore, since this design is primarily for small irrigation channels and is manually controlled, even if impurities enter the slots during long-term use, operators can easily detect and clean them according to their quantity.
[0006] To further optimize the process and facilitate manual removal of the gate, the lightweight gate is made of wood. Alternatively, a wooden stacked beam gate can be used for even better flow control.
[0007] Furthermore, the lightweight gate is made of pine wood. The lightweight gate is 5cm thick, free of insect holes and rot, and undergoes anti-corrosion treatment.
[0008] Further optimization involves the use of a rubber waterstop as a specific structure for a rubber seal.
[0009] To further optimize the installation of the rubber waterstop and prevent leakage caused by floating or misalignment, the rubber waterstop is glued along its entire length and fixed in the slot with cement nails.
[0010] To further optimize the design and prevent gaps at the joints of adjacent waterstops, the rubber waterstops on the downstream side and bottom of the slot are joined using heat-curing vulcanization. The joints of the waterstops can be bonded by overlapping at a 45-degree angle.
[0011] Further optimized, as a specific structure of a main channel, the main channel includes a channel base plate and channel side walls located on both sides, with the upper ends of the channel side walls inclined in opposite directions.
[0012] To further optimize the system and achieve water stoppage through a combination of a robust structure and a lightweight gate, a gate pier is provided between the outlet of the channel sidewall and the downstream channel. The gate pier has a channel with an open top in the middle. The outlet of the channel sidewall and the channel in the middle of the gate pier together form a water distribution outlet. The lightweight gate is located in the middle channel of the gate pier, and the slot is set along the circumferential sidewall of the middle channel of the gate pier. In this scheme, the gate pier is set at the outlet of the sidewall of the channel, the slot is set at the gate pier, and a stable water distribution system is formed by the cooperation of the gate pier and the lightweight gate.
[0013] To further optimize the process and increase the flow coefficient, both sides of the outlet are tapered slopes, which are arc-shaped and gradually curve toward the central channel of the gate pier.
[0014] Furthermore, the top of the channel sidewall is also provided with a channel capping.
[0015] Compared with the prior art, this utility model has the following advantages and beneficial effects: This utility model provides a water distribution structure for small irrigation channels. Using this solution, it is easy to operate in small irrigation channels, and the water intake can be freely controlled, while effectively preventing water seepage. Attached Figure Description
