The working principle of the present invention is illustrated in fig. 21, which is not limited to the actual size of the components.

The specific working process is as follows: when the closure plate mechanism designed by the invention is used, when the enclosure 4 is installed, firstly, the enclosure body 48 is placed on the upper side of the flood control dam 3, two persons press down the upper end of the enclosure body 48 to enable the lower end of the enclosure body 48 to be tightly attached to the upper end face of the flood control dam 3, the drill bit 22 is inserted into the flood control dam 3, at the moment, the downward pressure of the persons is transmitted to the third sliding threaded sleeve 27 through the guide shell 23, the first sliding threaded sleeve 18 and the second sliding threaded sleeve 25 in sequence, the third sliding threaded sleeve 27 transmits the downward pressure to the first compression spring 41 through the first installation ring 37, the first compression spring 41 transmits the downward pressure to the second installation ring 43, the second installation ring 43 is transmitted to the sliding sleeve 50, and the sliding sleeve 50 is transmitted to the drill bit 22 to enable the drill bit 22 to be inserted into the flood control dam 3; as shown in a in fig. 21, the input shaft 14 is then driven by external power, the input shaft 14 drives the third bevel gear 15 to rotate, the third bevel gear 15 drives the two fourth bevel gears 16 to rotate in opposite directions, the two fourth bevel gears 16 drive the two mounting rotating shafts 13 to rotate, the two mounting rotating shafts 13 drive the two second bevel gears 12 to rotate, the two second bevel gears 12 drive the two first bevel gears 11 to rotate, the two first bevel gears 11 drive the two driving rods 19 to rotate, the driving rods 19 drive the sliding sleeve 50 to rotate through the cooperation of the second sliding block 46 and the fourth sliding slot 45, and the sliding sleeve 50 drives the third sliding threaded sleeve 27 to rotate through the cooperation of the second mounting ring 43 and the friction ring 42; at this time, the second sliding threaded sleeve 25 is limited by the limiting block 20, so that the third sliding threaded sleeve 27 rotates and moves downwards relative to the second sliding threaded sleeve 25 under the matching of the threads, the third sliding threaded sleeve 27 moves downwards to extrude the first pressing spring 41 through the first mounting ring 37, and the second mounting ring 43 is extruded through the first pressing spring 41 to further drive the sliding sleeve 50 to move downwards; as shown in b of fig. 21, after the threaded ring 36 mounted on the third sliding threaded sleeve 27 contacts the bottom end of the threaded groove on the second sliding threaded sleeve 25, the third sliding threaded sleeve 27 stops moving downward relative to the second sliding threaded sleeve 25, and at this time, the upper end of the third sliding threaded sleeve 27 is disengaged from the two stoppers 20; the two limit blocks 20 lose the limit on the relative rotation of the second sliding threaded sleeve 25 and the first sliding threaded sleeve 18, and the second sliding threaded sleeve 25 can rotate relative to the first sliding threaded sleeve 18; in the rotating process, the two limit blocks 20 are pressed to slide towards the middle side of the second sliding threaded sleeve 25 under the action of the trigger inclined plane 21; at the same time, the second sliding threaded sleeve 25 moves downwards relative to the first sliding threaded sleeve 18, the second sliding threaded sleeve 25 drives the third sliding threaded sleeve 27 to move downwards through threaded fit, namely the sliding sleeve 50 moves downwards, and when the sliding sleeve 50 moves downwards to be close to the bottom end of the baffle body 48, the driving is stopped, as shown in c in fig. 21, at the moment, the second sliding threaded sleeve 25 moves downwards relative to the baffle body 48 by nearly half of the height, and a part of the second sliding threaded sleeve 25 is driven to be driven into the flood control dam 3 and is overlapped with the upper part of the sliding sleeve 50; the stability of fixing the sliding sleeve 50 and the flood control dam 3 is enhanced, and the stability of fixing the enclosing and blocking body 48 by the anchor rod mechanism 9 is improved.

When the retaining bodies 48 start to be fixed, the ends, which are matched with the connecting ring sleeves 7, of the two adjacent retaining bodies 48 are respectively distributed in a vertically staggered manner; after the retaining members 48 are fixed, all the retaining units 5 are fixed by passing the circular column 6 through all the connecting ring sleeves 7 at the mutually matched ends of two adjacent retaining members 48 from top to bottom.

Finally, the waterproof cloth 1 is installed on one side, close to the flood control dam 3, of the fence 4 with a slope surface through the buckle, and the lower end of the waterproof cloth 1 is fixed through the soil 2.
