[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] During the irrigation process of canal 1, when discharging water, for the irrigation diversion outlet, it is not only expected that the water level of the upstream water from the branch canal is kept as stable as possible, but also that the flow rate of the downstream water distribution to the branch canal is kept as stable as possible. The weir flow has a good function of stabilizing the water level. Therefore, in order to ensure that the water level of the upstream water and the flow rate of the downstream water distribution are as stable as possible, the ideal configuration is that the control gate adopts the weir flow method.

[0024] Based on the technical defects of the existing technology that require manual monitoring of water level height, which is prone to negligence and causes insufficient water storage, please refer to Figure 1-Figure 5 The utility model provides a water volume control device for a farmland water channel 1, wherein excess water can flow out from above a gate plate 2 5, thereby automatically preserving irrigation water at a suitable water level, and the gate plate 2 5 is height-adjustable, and a predetermined water level can be preserved according to actual irrigation water demand, and the utility model comprises a gate frame 2 embedded in the inner side of the water channel 1, a gate plate 1 4 and a gate plate 2 5 are disposed in the gate frame 2, and a control mechanism 3 for respectively controlling the lifting and lowering movement of the gate plate 1 4 and the gate plate 2 5 is installed on the top of the gate frame 2; the gate frame 2 is installed at the water channel 1, and the movement of the gate plate 1 4 and the gate plate 2 5 can be respectively controlled by the control mechanism 3, and when the movement of the gate plate 1 4 is controlled, water can be actively drained, so that the silt deposited at the bottom of the water channel 1 can be discharged to the downstream with the water flow, thereby reducing silt accumulation, and when the movement of the gate plate 2 5 is controlled, a predetermined water level can be preserved according to actual irrigation water demand.

[0025] To facilitate the control of the movement of gate 1 4 and gate 2 5, please refer to Figure 2The control mechanism 3 includes a box body 31 installed on the top of the gate frame 2, and a rotating assembly 32 is movably connected in the box body 31. The rotating assembly 32 is meshed with bevel gear 2 33 and bevel gear 4 34 respectively. A driving wheel 35 is fixed at the bottom of bevel gear 4 34, and the driving wheel 35 is transmission-connected with a driven wheel 36 through a belt. Bevel gear 2 33 and driven wheel 36 are respectively fixed on the tops of two lead screws 37, and the lead screw 37 is rotationally connected to the box body 31. The bottom of the lead screw 37 is spirally connected with a threaded sleeve 38, and the two threaded sleeves 38 are respectively fixed on the side walls of gate plate 1 4 and gate plate 2 5. When the rotating assembly 32 is meshed with bevel gear 4 34, the driving wheel 35 and the driven wheel 36 are used to rotate the lead screw 37 connected to gate plate 1 4, thereby controlling the lifting and lowering movement of gate plate 1 4. When the rotating assembly 32 is meshed with bevel gear 2 33, the lead screw 37 connected to gate plate 2 5 can be rotated, thereby controlling the lifting and lowering movement of gate plate 2 5.

[0026] To facilitate the control of the movement of gate plate 2 5, the rotating assembly 32 includes a rotating rod 321 rotatably connected to the inner side of the box body 31, one end of the rotating rod 321 extends to the outside of the box body 31 and is fixedly provided with a handwheel 322, and the other end of the rotating rod 321 is fixedly provided with a bevel gear 1 323 meshing with bevel gear 2 33. When it is necessary to control gate plate 2 5, the rotating rod 321 is pushed forward by the handwheel 322, and the rotating rod 321 drives the bevel gear 1 323 to contact and mesh with the bevel gear 2 33. At this time, rotating the handwheel 322 can control the lifting and lowering movement of gate plate 2 5.

[0027] To facilitate the control of the movement of gate plate 4, a spline sleeve 325 is sleeved on the outer wall of the rotating rod 321, and the spline sleeve 325 is rotatably connected to the inside of the box body 31. A spline 324 that can be embedded in the spline sleeve 325 is also provided on the outer wall of the rotating rod 321. The spline 324 is between the spline sleeve 325 and the bevel gear 1 323. A bevel gear 326 that meshes with the bevel gear 4 34 is fixed on the outer wall of the spline sleeve 325. When it is necessary to control the gate plate 4, the rotating rod 321 is pulled backward by the hand wheel 322, and the rotating rod 321 causes the spline 324 to move backward and insert into the spline sleeve 325. At this time, the hand wheel 322 can be turned to drive the bevel gear 326 to rotate through the rotating rod 321, the spline 324 and the spline sleeve 325, thereby controlling the lifting and lowering movement of the gate plate 4.

[0028] In order to prevent water from flowing out from the gap between the contact surface of the gate plate 1 4 and the gate plate 2 5, the opposite surfaces of the gate plate 1 4 and the gate plate 2 5 are closely fitted to reduce water leakage.

[0029] In order to prevent water from flowing out from the gap at the connection between the gate frame 2 and the gate plates 1 4 and 2 5, sliding grooves for the side movement of the gate plates 1 4 and 2 5 are opened on the two side walls inside the gate frame 2. The inner wall spacing of the sliding grooves is the sum of the thicknesses of the gate plates 1 4 and 2 5, which reduces the gap spacing and thus reduces leakage.

[0030] In order to improve the installation strength of the gate frame 2, an installation groove for the gate frame 2 to be embedded is opened on the inner side of the canal 1. When water is stored, the squeezing of the gate frame 2 by water can be distributed to the canal 1, making the installation of the gate frame 2 more stable.

[0031] Through the above embodiment, it can be known that: the gate frame 2 is installed at the water channel 1, and the movement of the gate plate 1 4 and the gate plate 2 5 can be controlled respectively by the control mechanism 3. When the gate plate 1 4 needs to be controlled, the rotating rod 321 is pulled backward by the hand wheel 322, and the rotating rod 321 makes the spline 324 move backward and insert into the spline sleeve 325. At this time, the rotating hand wheel 322 can drive the bevel gear 3 326 to rotate through the rotating rod 321, the spline 324 and the spline sleeve 325. The bevel gear 3 326 is meshed with the bevel gear 4 34 and is driven by the driving wheel 35 and the driven wheel 36. The lead screw 37 connected to the gate plate 1 4 is rotated to control the lifting movement of the gate plate 1 4. The movement of the gate plate 1 4 can actively drain water, so that the silt deposited at the bottom of the canal 1 is discharged to the downstream with the water flow, thereby reducing silt accumulation. When it is necessary to control the gate plate 2 5, the rotating rod 321 is pushed forward by the hand wheel 322, and the rotating rod 321 drives the bevel gear 1 323 to contact and mesh with the bevel gear 2 33, so that the lead screw 37 connected to the gate plate 2 5 can be rotated, thereby controlling the lifting movement of the gate plate 2 5, and the predetermined water level can be maintained according to the actual irrigation water demand.
