A limiting column 62110 is fixed to the top of the opening 6217, and the limiting column 62110 passes through the top of the second tooth plate 6219. The third compression spring 6214 supports the pressing block 6215. When the external rotating part is inserted into the square groove 6213 and the pressing block 6215 is squeezed, the pressing block 6215 moves downward, thereby driving the four first tooth plates 6216 to move downward, the four gears 6218 rotate, and the four second tooth plates 6219 move upward and retract into the opening 6217, making it convenient to unlock the knob 6212, and then the knob 6212 can be rotated.

[0030] In this embodiment, Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 11 As shown, a second slot 622 is provided at the top of the water stop frame 601, and the second tooth plate 6219 is engaged and connected in the second slot 622. The second tooth plate 6219 is initially engaged in the second slot 622, and the knob 6212 is in a locked state. When the external rotating part is inserted into the square slot 6213 and the pressing block 6215 is squeezed, the second tooth plate 6219 moves up and leaves the second slot 622, making it easy to unlock the knob 6212.

[0031] In this embodiment, Figure 4 、 Figure 5 and Figure 6As shown, the outer side of the screw rod 6211 is threadedly connected to the sleeve 623, and the sleeve 623 is slidably connected to the water stop frame 601, and a second movable plate 625 is fixed to the bottom of the sleeve 623, and a second groove 624 is provided at the top of the through hole 604.

[0033] The use method and advantages of the present invention: The working process of the water stop device for water conservancy project construction is as follows: like Figures 1 to 11As shown: first, place the support plate 3 on the two brackets 1 and make the threaded column 2 pass through the support plate 3, then put the nut 4 on the threaded column 2 and tighten it, so as to install the support plate 3. Use the lifting ring 602 and the external crane to assist in installing the water stop frame 601. When installing the water stop frame 601 on the support plate 3, it is necessary to clamp the clamping strip 603 in the first clamping groove 5. After the water stop frame 601 is extended into the water and touches the bottom, the plug column 620 is inserted into the bottom of the water. If the bottom of the water is uneven, there will be a height difference between the multiple plug columns 620, and the second piston 619 can Slide in the branch groove 618 to ensure that all the plugs 620 are inserted into the bottom of the water. When the second piston 619 slides upward in the branch groove 618, the first piston 615 slides upward in the slot 617, and the first movable plate 616 moves upward accordingly. Multiple water-stop frames 601 can be installed on the support plate 3. After the multiple water-stop frames 601 are spliced ​​together, an external rotating tool is inserted into the square groove 6213 and the pressing block 6215 is squeezed. The pressing block 6215 and the four first tooth plates 6216 move downward as a whole, and the four gears 62 18 rotation, the four second tooth plates 6219 move upward and leave the second slot 622, thereby unlocking the knob 6212, and then using the rotary tool to rotate the knob 6212, the screw rod 6211 rotates to drive the sleeve 623, the second movable plate 625, the extrusion plate 626 and the two third pistons 627 to move downward as a whole, and the extrusion plate 626 squeezes the water stop plate 606 to move to the left, and the water stop plate 606 extends into the through hole 604 of the adjacent water stop frame 601, and the sealing gaskets 609 on the two adjacent water stop plates 606 press tightly Together, they can strengthen the connection seal. The two air bags 630 expand and block the gaps between the multiple pins 620 to achieve a reinforcement effect. The rod 612 is inserted into the corresponding slot 617 to lock the first movable plate 616 and the pin 620. After the rotating tool is removed, the pressing block 6215 automatically pops up, and the second tooth plate 6219 moves down and is stuck back into the second slot 622 to lock the knob 6212. The use of the water stop frame 601 and the water stop plate 606 can stop water.
