A threaded opening is provided on one side of the second positioning block, and the driving rod applies a thrust to the second positioning block to move the second positioning block toward the inside of the top cover body. The top end of the second positioning block leaves the inside of the limiting groove, and the fixation of the top cover body is released. By pulling the top cover body upward, the top cover body is allowed to leave the top of the frame. By combining the frame and the top cover body in sections, the installation of the weir plate body is facilitated. At the same time, during use, the top cover body is disassembled to facilitate the maintenance of the weir plate body. Example

The top cover body 12 is moved, and at the same time, two first positioning blocks 16 are installed on the side end of the connecting block 15. The first positioning blocks 16 slide away inside the limiting groove 17 to release the fixation of the top cover body 12. The side end of each fixing plate 14 is fixedly installed with a connecting block 15, and the inner side of each connecting block 15 is fixedly installed with two first positioning blocks 16. The bottom end of the top cover body 12 has two downward protrusions, and a threaded opening is provided on one side of the second positioning block 24. The two side ends of the top cover body 12 are provided with grooves corresponding to the connecting blocks 15.
[0023] At least two limiting grooves 17 are provided at the two side ends of the frame 1, a slider 18 is slidably installed on the top of the fixing plate 14, and two first reset rods 19 are fixedly installed on the bottom end of the slider 18. A T-shaped rotating rod 13 is rotatably installed on the top end of the top cover body 12, and a gear set is installed at the end of the T-shaped rotating rod 13. By rotating the T-shaped rotating rod 13, the end of the T-shaped rotating rod 13 is rotatably connected with the driving rod 23 through a bevel gear 22, and the T-shaped rotating rod 13 pushes the driving rod 23 to rotate. A threaded opening is provided on one side of the second positioning block 24, and the driving rod 23 applies a thrust to the second positioning block 24 to move the second positioning block 24 toward the inside of the top cover body 12. The top end of the second positioning block 24 leaves the inside of the limiting groove 17 to release the fixation of the top cover body 12, and two driving rods 23 are rotatably installed on the bottom end of the top cover body 12, and the top end of each driving rod 23 is fixedly installed with a bevel gear 22, and the side end of each connecting block 15 is fixedly installed with a second reset rod 21.
[0024] Working principle:
[0025] In the first step, the frame 1 and the top cover body 12 are installed in a segmented combination. By pressing the top of the slider 18, the slider 18 presses the first reset rod 19 downward, and the first reset rod 19 is retracted, so that the slider 18 slides downward into the top of the fixed plate 14, and at the same time pushes the fixed plate 14, so that the fixed plate 14 slides along the top of the top cover body 12. The fixed plate 14 pushes the connecting block 15 to slide on the side end of the top cover body 12, and at the same time, two first positioning blocks 16 are installed on the side end of the connecting block 15. The first positioning block 16 is at The inside of the limiting groove 17 slides away, releasing the fixation of the top cover body 12, and by rotating the T-shaped rotating rod 13, the end of the T-shaped rotating rod 13 is rotatably connected with the driving rod 23 through the bevel gear 22, and the T-shaped rotating rod 13 pushes the driving rod 23 to rotate. A threaded opening is provided on one side of the second positioning block 24, and the driving rod 23 applies a thrust to the second positioning block 24, so that the second positioning block 24 moves toward the inside of the top cover body 12, and the top end of the second positioning block 24 leaves the inside of the limiting groove 17, releasing the fixation of the top cover body 12.
[0026] In the second step, the top cover body 12 is pulled upward to make the top cover body 12 leave the top of the frame 1. By combining the frame 1 and the top cover body 12, it is convenient to install the weir plate body 11. At the same time, during use, the top cover body 12 is disassembled to facilitate the maintenance of the weir plate body 11. By rotating the T-shaped rotating rod 13 in the opposite direction, the T-shaped rotating rod 13 pushes the driving rod 23 to rotate, so that the driving rod 23 drives the second positioning block 24 to move, and the second positioning block 24 is inserted into the inside of the limiting groove 17 to one side for fixing, and at the same time, the connecting block 15 is pushed to slide on the side end of the top cover body 12, and the connecting block 15 drives the first positioning block 16 to be inserted into the inside of the limiting groove 17. The position of the top cover body 12 is fixed by multiple fixing mechanisms, which is convenient for operation and increases the stability of the connection between the frame 1 and the top cover body 12. The connecting block 15 squeezes the top of the second reset rod 21, forcing the second reset rod 21 to retract. At the same time, the fixing plate 14 moves at the top of the top cover body 12, and the slider 18 contacts the support rod of the T-shaped rotating rod 13, and is squeezed and moves downward to squeeze the first reset rod 19. After moving through the T-shaped rotating rod 13, under the reverse force of the first reset rod 19, the slider 18 moves upward and contacts the support rod of the T-shaped rotating rod 13, and connects the T-shaped rotating rod 13 and the connecting block 15 through the fixing plate 14. While fixing the connecting block 15, the rotation of the T-shaped rotating rod 13 is restricted.
