[0028] Such as Figures 1 to 5As shown in the figure, a water-blocking device for farmland water conservancy diversion includes: a fixing frame 1. A through hole 101 is provided on the outer side of the fixing frame 1, and the through hole 101 penetrates the fixing frame 1. A groove 102 is provided inside the through hole 101. The groove 102 penetrates one end of the fixing frame 1, and the opening direction of the groove 102 is perpendicular to the opening direction of the through hole 101. A flow-limiting mechanism is arranged inside the fixing frame 1 and is used to block the water flow. The flow-limiting mechanism includes a rotating member 2 and a control member 3. The control member 3 is arranged inside the fixing frame 1, the rotating member 2 is arranged inside the control member 3, and the rotating member 2 cooperates with the control member 3 to control the water flow rate. A limiting member 4 is arranged outside the control member 3 and is used to fix the rotation angle of the rotating member 2. Specifically, when controlling the water diversion opening of the water channel, first install the fixing frame 1 outside the water diversion opening, and then control the water flow at the water diversion opening through the cooperation of the control member 3 and the rotating member 2. While controlling the water flow at the water diversion opening, adjust the water flow rate through the limiting member 4, so that the water diversion opening can be controlled according to actual needs. During use, the fixing frame 1 needs to be pre-installed inside the water diversion opening. The fixing frame 1, the rotating member 2 and the control member 3 are all made of corrosion-resistant materials to avoid corrosion and damage caused by long-term contact with water. During use, water flows inside the through hole 101, and the on-off of the water is controlled by adjusting the position of the control member 3 relative to the fixing frame 1.
[0029] As Figures 1 to 5 shown, a plurality of ear plates 103 are further provided on the outer side of the fixing frame 1. Specifically, during use, the contact area between the fixing frame 1 and the water channel is increased through the ear plates 103, so as to prevent the fixing frame 1 from moving under the push of water pressure and further ensure the stability of the fixing frame 1 during use. The shape of the ear plates 103 is not limited in any way and can be in the shape of a semi-circular plate or a long strip, etc. The ear plates 103 and the fixing frame 1 can be connected by threads or welded.
[0030] As Figures 1 to 5As shown in the figure, the control member 3 includes a sliding plate 301 which slides inside the groove 102, and the sliding direction of the sliding plate 301 is parallel to the height direction of the fixing frame 1. Rotating grooves 303 and connecting grooves 304 are respectively formed inside the sliding plate 301, and the rotating groove 303 communicates with the connecting groove 304. A plurality of second through grooves 302 are formed on the outer side of the sliding plate 301. The second through grooves 302 penetrate through the sliding plate 301, and the opening direction of the second through grooves 302 is parallel to the opening direction of the through hole 101. Specifically, when blocking the water at the water diversion port, first insert the sliding plate 301 completely into the groove 102 so that the sliding plate 301 is in close contact with the groove 102, thereby realizing the truncation of the water flow at the water diversion port. The groove 102 penetrates through the top of the fixing frame 1, providing guidance during the process of inserting the sliding plate 301 into the fixing frame 1 and preventing the sliding plate 301 from shifting relative to the fixing frame 1. The shape of the second through groove 302 can be fan-shaped or strip-shaped, etc., so as to balance the water pressure on both sides of the sliding plate 301 in cooperation with the rotating member 2 during the process of adjusting the position of the sliding plate 301, reducing the resistance when the sliding plate 301 moves. A limiting rod is further provided on the outer side of the fixing frame 1. The limiting rod is connected to the fixing frame 1 by a thread. The limiting rod and the fixing frame 1 cooperate to be able to abut against the sliding plate 301, thereby fixing the position of the sliding plate 301 during use and preventing the sliding plate 301 from shifting relative to the fixing frame 1 after adjustment.
[0031] As Figures 1 to 5As shown in the figure, the rotating member 2 includes a rotating disk 201. The rotating disk 201 rotates inside the rotating groove 303. A plurality of first through grooves 202 are formed inside the rotating disk 201. The first through grooves 202 correspond to the second through grooves 302, and the opening directions of the first through grooves 202 are parallel to the opening directions of the second through grooves 302. A connecting rod 203 is provided outside the rotating disk 201, and the connecting rod 203 slides inside the connecting groove 304. Specifically, the rotating disk 201 is controlled to rotate relative to the sliding plate 301 through the connecting rod 203, so that the first through grooves 202 and the second through grooves 302 are staggered and overlapped, thereby cooperating with the sliding plate 301 to intercept and conduct the water flow at the water diversion port. During use, the rotating disk 201 can completely block the second through grooves 302 to prevent water from leaking through the gap between the second through grooves 302 and the rotating disk 201. The first through grooves 202 and the second through grooves 302 have the same shape. Before adjusting the position of the sliding plate 301, first drive the rotating disk 201 to rotate through the connecting rod 203, so that the first through grooves 202 and the second through grooves 302 overlap, enabling the water on both sides of the sliding plate 301 to flow through. Thus, during the movement of the sliding plate 301, the pressure on both sides of the sliding plate 301 is balanced, reducing the resistance when pushing the sliding plate 301 to move. When it is necessary to control the water flow rate, the overlapping range of the first through grooves 202 and the second through grooves 302 can be adjusted, the position of the sliding plate 301 relative to the fixed frame 1 can be adjusted, or the position of the sliding plate 301 relative to the fixed frame 1 can be adjusted while adjusting the overlapping range of the first through grooves 202 and the second through grooves 302, increasing the range of flow rate adjustment while accurately controlling the flow rate.
[0032] As Figures 1 to 5 shown, the limiting member 4 includes a sliding block 401. The sliding block 401 slides inside the groove 102. An installation hole 402 is formed outside the sliding block 401. A connecting sleeve 403 is provided inside the installation hole 402. The connecting sleeve 403 is sleeved outside the connecting rod 203. A bolt 404 is provided outside the sliding block 401, and the bolt 404 is connected to the fixed frame 1. Specifically, during the process of driving the rotating disk 201 to rotate by the connecting rod 203, the angle of the connecting rod 203 is fixed through the cooperation of the connecting sleeve 403 and the sliding block 401, preventing the adjusted angle of the rotating disk 201 from changing. The sliding block 401 slides inside the groove 102, thereby guiding the rotation direction of the connecting rod 203. The connecting sleeve 403 connects the sliding block 401 and the connecting rod 203, and the bolt 404 connects the sliding block 401 and the fixed frame 1. Thus, after the adjustment of the rotating disk 201 is completed, the angle of the connecting rod 203 is maintained through the sliding block 401, ensuring the stability of the adjusted angle of the rotating disk 201.
[0033] As Figures 1 to 5As shown, fixing holes are formed on the outer side of the sliding plate 301. A connecting shaft is arranged inside the fixing holes. The connecting shaft rotates inside the fixing holes and is connected to the rotating disk 201. Specifically, the connecting shaft cooperates with the fixing holes to support the rotating disk 201, reducing the friction between the rotating disk 201 and the sliding plate 301 while preventing the rotating disk 201 from wobbling relative to the sliding plate 301, ensuring the stability of the rotating disk 201 during use.
