[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1 to 5 In the embodiment of the present invention, the wall-penetrating sealing device of the bottom shaft of the steel dam gate includes two water-sealing sleeves 1. The ends of the two water-sealing sleeves 1 close to each other are fixedly connected with a rubber ring 2. The ends of the two water-sealing sleeves 1 away from each other are integrally formed with a connecting flange 5, and the middle sections of the outer walls of the two water-sealing sleeves 1 are integrally formed with a protruding ring 3. The ends of the two protruding rings 3 away from each other are provided with screws 4 that penetrate into the outside of the connecting flange 5. The outer walls of the screws 4 are threadedly connected with locking nuts 7 for tightening the connecting flange 5. End face seals 6 are installed on the end surfaces of the two connecting flanges 5 close to each other. The tightened connecting flanges 5 are used to drive the end face seals 6 to fit tightly against the wall; one connecting flange 5 is located outside the river channel, and the other connecting flange 5 is located inside the river channel. A protective mechanism is installed at one end of the connecting flange 5 inside the river channel, which is used to further improve the waterproof performance of the water-sealing sleeve 1.

[0022] In this embodiment: first, two water sealing sleeves 1 and rubber rings 2 are installed in the waterway gate wall, and then holes aligned with the connecting flanges 5 are drilled on the inner and outer surfaces of the gate wall, and chemical plugs are installed in the holes. Then, screws 4 are passed through the connecting flanges 5 and screwed into the holes, and the chemical plugs are broken. After the chemical plugs are solidified, the locking nuts 7 are tightened on the outside of the screws 4. During the tightening process, the locking nuts 7 effectively squeeze the connecting flanges 5. At this time, the connecting flanges 5 can drive the end face seals 6 to fit tightly against the gate wall surface to form a sealing effect. During this process, the rubber rings 2 are squeezed and deformed. In the subsequent process of thermal expansion and contraction of the concrete, the rubber rings 2 can also be deformed accordingly to avoid separation from the concrete. After the connecting flanges 5 are fixed, concrete is poured at the installation position (between the two protruding rings 3). The provision of the protruding rings 3 can increase the contact area between the device and the concrete.

[0023] After the concrete is dry, the protective mechanism is installed through the installation mechanism. The protective mechanism protects the connecting flange 5 located inside the gate wall to prevent water erosion and corrosion of the connecting flange 5 located inside.

[0024] Please refer to Figure 2 and Figure 3The protection mechanism includes a protection shell 8, the cross section of the protection shell 8 is a "C"-shaped structure, and a sealing ring 9 is installed on the outer periphery of the outer ring portion of the protection shell 8. The protection shell 8 is connected to another connecting flange 5 through an installation mechanism.

[0025] In this embodiment, the protective shell 8 is installed by the installation mechanism. After the protective shell 8 is installed, the sealing ring 9 is in close contact with the circular hole on the inner side of the gate wall. At this time, the sealing ring 9 is squeezed to protect the connecting flange 5 located on the inner side.

[0026] Please refer to Figure 3 、 Figure 4 and Figure 5 The mounting mechanism includes a plurality of fixing ears 10 integrally formed on the outer periphery of the connecting flange 5, and the plurality of fixing ears 10 are equidistantly distributed circumferentially. The mounting mechanism also includes a rotating screw 11 rotatably connected to the protective shell 8, and the inner side of the protective shell 8 is fixedly connected to a docking column 12 that is plugged into the central hole portion of the fixing ear 10. A through groove 13 is provided on the outer periphery of the docking column 12, which penetrates to the lower part of the outer periphery of the docking column 12. One end of the rotating screw 11 penetrates into the inner cavity of the through groove 13, and the outer wall of the rotating screw 11 is threadedly connected to a sliding block 14 that is slidably connected to the through groove 13. The mounting mechanism also includes sliding grooves provided at the upper and lower parts of the interior of the sliding block 14. The sliding groove has a "convex" structure, and the inner wall of the sliding groove is slidably connected to a limit block 16. A spring 15 is fixedly connected between one end of the limit block 16 and the inner wall of the sliding groove, and a pressure inclined surface 17 is integrally formed on the end of the limit block 16 away from the sliding block 14.

[0027] In this embodiment: when the protective shell 8 is installed, the protective shell 8 drives the docking column 12 to align with the center hole of the fixing ear 10. During the process of plugging the docking column 12 and the fixing ear 10, when the limit block 16 contacts the fixing ear 10, the compressed inclined surface 17 is squeezed with the fixing ear 10. At this time, the two limit blocks 16 are forced to slide along the sliding groove on the inner wall of the sliding block 14. At this time, the spring 15 is squeezed until the limit block 16 is completely misaligned with the fixing ear 10. At this time, the spring 15 is reset, and the reset spring 15 pushes the limit block 16 to reset and pop out. Then, a tool is used to connect the cross groove at one end of the rotating screw 11, and the rotating screw 11 is driven to rotate by the tool. At this time, the sliding block 14 moves along the through groove 13, and the moving sliding block 14 drives the limit block 16 to move synchronously. The flat portion of the limit block 16 is tightly against one side of the fixing ear 10, and the protective shell 8 can be fixed.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
