Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments, wherein the dimensional ratios in the drawings do not represent actual dimensional ratios, and are only used for representing relative positional relationships and connection relationships between components, and the components with the same names or the same reference numbers represent similar or identical structures and are only used for illustrative purposes.
As shown in fig. 1, the irrigation area gate in the prior art is usually arranged on the straight section of the channel, and is arranged along the right section of the incoming flow of the channel, where the right section is perpendicular to the incoming flow direction. The utility model discloses a setting mode of irrigated area gate in the channel is the same with it.
As shown in figure 2, the irrigation area gate comprises a gate plate 1 which is used for closing a channel along the incoming flow normal section of the channel, the gate plate 1 is provided with a rotating shaft 2 fixedly connected with the gate plate 1, the rotating shaft 2 is arranged at the middle position of the horizontal direction of the gate plate 1, and the rotating shaft 2 is arranged along the vertical direction. The rotating shafts 2 are symmetrically arranged along the vertical axis, and the rotating shafts 2 are arranged in the middle of the horizontal direction of the flashboard 1, namely the position of the vertical symmetrical axis of the flashboard 1. At this moment, the projection areas of the flashboards 1 positioned on the two sides of the rotating shaft 2 in the incoming flow direction F are equal in the rotating process, and the flashboards are offset by the resistance moment of water flow in the rotating process, so that the rotating resistance of the flashboards 1 is small, the use of small power for opening is facilitated, and the fast opening speed is ensured.
During installation, a fixed truss 3 is usually arranged above the ditch, one end of the rotating shaft 2 is rotatably arranged on the fixed truss 3, and the other end of the rotating shaft is rotatably arranged at the bottom of the ditch. The upper part of the rotating shaft 2 is connected with a power system through a transmission device. Specifically, the transmission device may be a transmission gear engaged with the power system and disposed above the fixed truss 3 and the rotating shaft 2, or a belt rotating device connecting the power system and the rotating shaft 2. In view of the use conditions, it is preferable to use a gear mesh transmission. In powered channel gates, the power system is typically a motor that incorporates a speed reducer to achieve low speed, high torque output. In unpowered channel gates, the power system may be a rotating hand wheel and associated speed reduction mechanism. Because do not need to use screw drive, its mechanical efficiency is higher than current over-and-under type gate, and is lower to driving system's requirement, and on the other hand, the switching in-process comes the moment of resistance to the gate and offsets at pivot both sides, therefore the opening speed of flashboard 1 can be accomplished to be higher than current over-and-under type gate, especially is fit for in the occasion that needs frequently open and close.
