[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Combination Figures 1-6 A seepage prevention structure for a water conservancy channel includes a water channel 1. Two filter plates 3 are fixedly connected inside the water channel 1. A seepage prevention plate 2 is placed between the two filter plates 3. Fixing plates 4 are fixedly connected to the top of the seepage prevention plate 2 on both sides. Fixing bolts 5 are threadedly connected to the top of the two fixing plates 4. Filter holes 6 are opened through the front and rear of the two filter plates 3.

[0026] In actual operation, the seepage-proof plate 2 is fixed inside the water channel 1 by the cooperation of two fixing bolts 5 and two fixing plates 4, and is located between two filter plates 3. The water in the water channel 1 cannot pass through the seepage-proof plate 2, thereby preventing the water in the water channel 1 from seeping.

[0027] Specifically, when the seepage barrier 2 is removed, the water in the canal 1 will pass through the two filter plates 3 and flow to one end of the canal 1. At the same time as the water passes through the two filter plates 3, the floating grass in the canal 1 will be filtered by several filter holes 6 to prevent the floating grass from entering the farmland when the canal 1 irrigates the farmland, and then growing in the farmland and competing for the nutrients of the crops.

[0028] See Figure 2 and Figure 3The filter plate 3 is trapezoidal, and the filter plate 3 is fixedly attached to each inner wall of the water channel 1.

[0029] Referring to Figure 3 The distance between the two filter plates 3 is consistent with the width of the impermeable plate 2, and a plurality of placement grooves 7 are arranged in the front and rear portions of the impermeable plate 2 from top to bottom.

[0030] Referring to Figure 4 The inside of each placement groove 7 is slidably connected with a dredging rod 11, and the inside of the impermeable plate 2 near the front and rear portions and at one end of each row of placement grooves 7 is slidably connected with an extrusion block 8.

[0031] Specifically, the extrusion block 8 is pressed downward, and since one end of the dredging rod 11 is arranged in a slope and the front portion of the extrusion block 8 is also arranged in a slope, the angle of the slope of one end of the dredging rod 11 and the front portion of the extrusion block 8 is complementary, so that when the extrusion block 8 moves downward, the dredging rod 11 is pressed to slide along the placement groove 7 through the slope, and when the dredging rod 11 enters the filter hole 6, the filter hole 6 can be dredged.

[0032] Referring to Figure 5 and Figure 6 One end of the dredging rod 11 is arranged in a slope, and the front portion of the extrusion block 8 is also arranged in a slope, the angle of the slope of one end of the dredging rod 11 and the front portion of the extrusion block 8 is complementary, and one end of the dredging rod 11 is in contact with the front portion of the extrusion block 8.

[0033] Referring to Figure 3 and Figure 4 The top portions of the front and rear two extrusion blocks 8 at the top of the top portion are fixedly connected with a connecting plate 9 penetrating through the top portion of the impermeable plate 2, and a lifting groove is arranged in the top portion of the impermeable plate 2 at the bottom of the connecting plate 9.

[0034] Specifically, the screw rod 10 is rotated to drive the connecting plate 9 to move downward along the lifting groove, and in turn drive all the extrusion blocks 8 near the front and rear portions to move downward together, and in turn drive the dredging rod 11 to slide along the placement groove 7.

[0035] Referring to Figure 5 A straight groove is arranged in the outer surface of each dredging rod 11 in the impermeable plate 2, a limiting plate 12 is fixedly connected to the outer surface of the dredging rod 11 at one end and in the straight groove, and a spring 13 is fixedly connected between the limiting plate 12 and the straight groove.

[0036] Specifically, when the dredging rod 11 slides along the placing groove 7, the limiting plate 12 is driven to slide along the straight groove, and the spring 13 is compressed, when the extrusion block 8 moves upward, the spring 13 is driven to reset the dredging rod 11 through the elastic force.

[0037] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
