The extracted silt contains a large amount of water, which is easy to destroy the water balance, and the silt removal efficiency is low. The water flow with silt easily passes over the device, and the silt removal effect is poor. When the river water with silt passes through, the guide plate 1 is set to block the silt through the guide plate and stay at the bottom of the inner wall of the guide plate. The river water flows downstream through the through groove 2, which can effectively improve the convenience of the operator when cleaning the silt. It is known to those skilled in the art that the guide plate 1 placed on the riverbed is easy to move due to the impact of the river water.
[0027] In this embodiment, a mounting plate 3 is fixedly connected to one side of the guide plate 1, and a plurality of fixing nails 4 are fixedly connected to the bottom end of the mounting plate 3. The interior of the fixing nail 4 is provided with a threaded hole 41, an extrusion chamber 42 and a sliding groove 43 in sequence from top to bottom, and the threaded hole 41, the extrusion chamber 42 and the sliding groove 43 are connected from top to bottom. The internal thread of the threaded hole 41 is connected with a bolt 44, and the top of the bolt 44 passes through the mounting plate 3 and extends to the top of the mounting plate 3 and is threadedly connected to the mounting plate 3. An extrusion block 45 is provided in the extrusion chamber 42, and the extrusion block 45 is slidably connected to the extrusion chamber 42. There are movable Hole 431, the inner wall of the movable hole 431 is movably connected with an insertion rod 432, the inner end of the insertion rod 432 is fixedly connected with a limiting block 433 in the sliding groove 43, the upper and lower ends of one side of the limiting block 433 are fixedly connected with a limiting spring 434, and the other side of the limiting spring 434 is fixedly connected to the inner wall of the sliding groove 43, and a plurality of first through holes 31 are opened on the upper surface of the mounting plate 3 and between the two fixing nails 4, and buried nails 5 are arranged in the plurality of first through holes 31, and the outer surface of the buried nail 5 is provided with a thread, and the upper end of the buried nail 5 is fixedly connected with a fixing block 51, and the buried nail 5 is threadedly connected to the first through hole 31.
[0028] When it is necessary to fix the guide plate 1, the fixing nail 4 is provided to press the mounting plate 3 so that the fixing nail 4 is fixed downward inside the riverbed, and then the bolt 44 is rotated to move downward, and the bolt 44 is downwardly abutted against the extrusion block 45 in the extrusion chamber 42 to drive the extrusion block 45 downward, and the extrusion block 45 presses the limit block 433 downward, so that the limit block 433 moves to the left and right sides, thereby driving the insertion rod 432 to move to the left and right sides, and inserting it into the riverbed horizontally through the movable hole 431, thereby increasing the force bearing area of the fixing nail 4 and the riverbed, and making the fixing nail 4 more stable when in use, and then making the fixing effect of the guide plate 1 better, and it will not flow with the water flow; at the same time, the buried nail 5 also moves downward, so that the buried nail 5 enters the riverbed for a section, and the fixing effect of the guide plate 1 can be further improved by rotating the buried nail 5, and the buried nail 5 is rotated deeply into the riverbed by rotating the buried nail 5, so that the guide plate 1 is more firmly fixed on the riverbed.
[0029] Moreover, an inverted cone block 451 is fixedly connected to the bottom end of the extrusion block 45 , and a horizontal cone block 435 is fixedly connected to the outer end of the insertion rod 432 .
[0030] The inverted tapered block 451 at the bottom of the extrusion block 45 is more conducive to extruding the limit blocks 433 on both sides, so that the two limit blocks 433 move to both sides; the horizontal tapered block 435 at the outer end of the insertion rod 432 is more conducive to inserting the insertion rod 432 into the riverbed.
[0031] In addition, the vertical height and horizontal width of the limiting block 433 are both greater than the movable hole 431 , and the upper sides of the mutually adjacent ends of the limiting block 433 are both inclined toward the middle.
[0032] This can prevent the insertion rod 432 from moving too much to the left and right, and move the limiting block 433 out of the sliding groove 43. The limiting block 433 with an inclined upper end is more conducive to cooperating with the extrusion block 45 to be extruded.
[0033] In addition, grooves 511 are arranged on both sides above the fixing block 51 , a roller is fixed on the top of the groove 511 , a cross bar 512 is arranged on the roller, and a handle 513 is fixed on the upper end surface of the cross bar 512 .
[0034] By grabbing the handle 513 and rotating it, the buried nail 5 can be rotated and inserted into the riverbed. The operation is simple and convenient for the user to install, and there is no need to carry other installation tools.
[0035] At the same time, a guide base 6 is arranged on the other side of the through slot 2 away from the mounting plate 3 , and the cross section of the guide base 6 is arranged to be a quarter arc surface, and the arc side surface of the guide base 6 faces the water entry direction.
[0036] By setting the guide base 6, when the through groove 2 of the guide plate 1 is impacted by water flow, the wedge-shaped surface can guide the water flow, reduce the direct impact of the water flow, and to a certain extent, intercept some silt.
[0037] Secondly, the guide plate 1 is arranged in a V shape, and the mounting plate 3 and the guide plate 1 are formed integrally.
[0038] The guide plate 1 is V-shaped, and the inclination angle of the guide plate 1 blocks the silt, and the silt stays at the bottom of the inner wall of the guide plate 1, and the river water flows downstream through the through groove.
[0039] In addition, extension plates 7 are symmetrically and movably installed inside the guide plate 1, and the two extension plates 7 are slidably connected to the guide plate 1. A hinge is fixedly installed on the inner wall of the two extension plates 7 away from the guide plate 1, and an arc plate 8 is fixedly installed on the outer surface of one side of the two hinges. Side nails 9 are fixedly installed on the outer wall of the two arc plates 8 away from the hinge.
[0040] By setting the extension plate 7, the arc plate 8 and the side nails 9, the extension plate 7 is moved along the guide plate 1 so that the end away from the guide plate 1 can be fitted with the side wall of the riverbed. In this process, the arc plate 8 is brought into contact with the side wall of the riverbed and the side nails 9 are buried in the side wall of the riverbed, so that the arc plate 8 can be closely fitted with the side wall of the riverbed, which can effectively prevent the river water with silt from flowing from the side of the device, thereby improving the blocking effect of silt.
[0041] Furthermore, a filter grid 10 is fixedly mounted on the inner wall of the through groove 2 .
[0042] The filter grid 10 can block impurities in the river water and can also clean up garbage and impurities during the dredging process, thereby improving the cleanliness of the river.
[0043] When in use, by placing the guide plate 1 in the riverbed, when the river water with silt passes by, the silt is blocked by the guide plate 1 and stays at the bottom of the inner wall of the guide plate 1, and the river water flows downstream through the through groove 2, which can effectively improve the convenience of the operators in cleaning the silt, reduce the scope of silt cleaning, and further enhance the dredging efficiency. When it is necessary to fix the guide plate 1 to prevent displacement caused by the impact of the river water, first press the mounting plate 3 downward to fix the fixing nail 4 downward inside the riverbed, and then rotate the bolt 44 to move downward, the bolt 44 is downwardly abutted against the extrusion block 45 in the extrusion chamber 42, driving the extrusion block 45 downward, and the extrusion block 45 squeezes the limit block 433 downward, so that the limit block 433 moves to the left and right, thereby driving the insertion rod 432 to move to the left and right. At this time, the limit spring 434 is squeezed and inserted into the riverbed horizontally through the movable hole 431, so that the fixed The force-bearing area of the fixed nail 4 and the riverbed can make the fixed nail 4 more stable when in use; at the same time, the buried nail 5 also moves downward, so that a section of the buried nail 5 enters the interior of the riverbed, and the buried nail 5 can be rotated and inserted into the riverbed by grasping the handle 513 and rotating it. By rotating the buried nail 5, the buried nail 5 is deeply rotated and entered into the interior of the riverbed, so that the guide plate 1 is more firmly fixed on the riverbed; when it is necessary to shift the guide plate 1, grasp the handle 513 and rotate the buried nail 5 in the opposite direction, so that the buried nail 5 is moved out of the riverbed, and then the bolt 44 is rotated in the opposite direction to move upward, so that the pressure of the bolt 44 on the extrusion block 45 disappears, and the extrusion force of the limit spring 434 also disappears. Under the action of the elastic force of the limit spring 434, the insertion rod 432 moves into the sliding groove 43, so that the insertion rod 432 is moved out of the interior of the riverbed, and the mounting plate 3 is lifted upward to move the guide plate 1 to a suitable position.
