[0052] Example: Figures 1 to 7As shown, a separable gate water-stopping device for waterways or rivers includes a water-stopping mechanism 7 located on the water-facing or back-facing side of a steel gate 10 near both sides, and a water-stopping drive push rod 3 located inside each water-stopping mechanism 7.

[0053] Each water-stopping mechanism 7 includes a U-shaped rubber water-stop 7-2 whose length matches the height of the corresponding side of the steel gate 10;

[0054] Each U-shaped rubber waterstop 7-2 is connected to the steel gate 10 in a sliding pair, and the side used for sealing can reciprocate towards the gate wall 9 on the corresponding side of the steel gate 10;

[0055] Each water-stopping drive push rod 3 includes a steel rod 3-1 that is connected to the steel gate 10 in a sliding pair;

[0056] Each steel bar 3-1 can reciprocate along the opening and closing direction of the steel gate 10. It is connected to the corresponding U-shaped rubber waterstop 7-2 by several connecting rods 4 to form a double slider mechanism. When any steel bar 3-1 moves upward relative to the steel gate 10, it pushes the corresponding U-shaped rubber waterstop 7-2 to move towards the gate wall 9 on the corresponding side of the steel gate 10 through the corresponding connecting rods 4.

[0057] When the steel gate 10 is closed, under the weight of the steel gate 10 or the closing force, each steel bar 3-1 is lifted by the gate bottom plate 11 below the steel gate 10. The push rod 3 pushes the connecting rod 4, and the connecting rod 4 pushes the U-shaped rubber water stop 7-2 to press against the side of the gate wall 9 to achieve water stop.

[0058] When the steel gate 10 opens and rises, each steel bar 3-1 falls, the water-stopping mechanism 7 separates from the gate wall 9, and the water stop no longer rubs against the wall surface.

[0059] like Figure 12 and Figure 13 As shown, in some embodiments, each U-shaped rubber waterstop 7-2 is disposed within a waterstop box 8 with a cross-section of "U" or "h" shaped;

[0060] Each water-stop box 8 is located on the water-facing or back-facing side of the steel gate 10 near both sides, and is fixedly connected to the steel gate 10 to form a water seal. The length direction is parallel to the corresponding gate wall 9, the side of the opening faces the corresponding gate wall 9, and the bottom of the opening has several openings along the length direction.

[0061] Each U-shaped rubber waterstop 7-2 faces the bottom of the corresponding waterstop box 8 opening, and a pusher 7-4 is provided for each opening. The pusher 7-4 and the corresponding opening at the bottom of the corresponding waterstop box 8 are connected to the steel gate 10 to form a moving pair.

[0063] Each pair of inner pressure plates 7-1 and corresponding outer pressure plates 7-3 are provided with several bolts 7-5 along the length direction to press the corresponding U-shaped rubber waterstops 7-2;

[0064] Each external pressure plate 7-3 has a corresponding pusher 7-4 on the side facing the bottom of the opening of the corresponding waterstop box 8.

[0065] In practical applications, the U-shaped rubber waterstop 7-2 is installed in the groove of the side opening of the waterstop box 8, and the pusher 7-4 passes through the opening at the bottom of the opening of the waterstop box 8 and forms a moving pair connection with the steel gate 10.

[0066] In some embodiments, a water seal is formed between each water-stop box 8 and the steel gate 10 by providing a flat rubber water-stop 6.

[0067] like Figure 8 and Figure 9 As shown, in some embodiments, each steel bar 3-1 is provided with a reverse thrust device 1 at its upper end;

[0068] Each thrust reverser 1 includes a spring 1-2 and a spring retainer 1-1;

[0069] Each spring fixing seat 1-1 has an opening at the bottom, external threads on the outside, and a hollow external thread blind tube inside;

[0070] Each spring fixing seat 1-1 has a corresponding steel rod 3-1 inserted into its lower opening, and is connected to the corresponding steel rod 3-1 in a sliding pair. Each spring fixing seat 1-1 is equipped with a corresponding spring 1-2, which presses the corresponding steel rod 3-1 down. Each spring fixing seat 1-1 is fixed to the water-facing or water-repellent side of the steel gate 10 by a top support 2-1 with internal threads on the outside.

[0071] In practical applications, the spring fixing seat 1-1 and the support 2-1 of the thrust reverser 1 are connected by threads. By rotating the spring fixing seat 1-1 and moving it up and down, the clamping force of the spring 1-2 can be adjusted, thereby adjusting the magnitude of the thrust reverser.

[0072] like Figure 10 , Figure 11 and Figure 14 As shown, in some embodiments, each steel bar 3-1 forms a movable pair with the steel gate 10 through several supports fixed to the water-facing or water-repellent side of the steel gate 10.

[0073] The supports include the unrestricted rotation support 2-2 and the restricted rotation support 2-3;

[0074] Each non-rotational support 2-2 includes a ring that is in clearance fit with the corresponding steel bar 3-1, and a support structure that fixes the corresponding ring to the water-facing or water-repellent side of the steel gate 10.

[0076] Each steel bar 3-1 is provided with a rotation limiting block 3-3 at the position corresponding to each guide groove, which matches the corresponding guide groove.

[0077] In practical applications, a rotation limiting block 3-3 is welded to the side of the steel bar 3-1 and is located in the guide groove with the rotation limiting support 2-3 to restrict the rotation of the steel bar 3-1.

[0078] In some embodiments, a connecting rod lug 3-2 is welded to the position where each steel rod 3-1 connects to the corresponding connecting rod 4, and the connecting rod lug 3-2 is hinged to the corresponding connecting rod 4.

[0079] like Figure 16 As shown, in some embodiments, each steel bar 3-1 has an adjusting support 5 at its lower end;

[0080] Each adjusting support 5 includes a threaded connection part connected to the corresponding steel bar 3-1, and a joint support provided at the lower end of the corresponding threaded connection part.

[0081] In practical applications, the lower end of the steel rod 3-1 of the adjusting base 5 is threadedly connected to the push rod 3, which can adjust the extension length and the distance of pushing the water-stopping mechanism 7, i.e. the degree of compression between the U-shaped rubber 7-2 and the gate wall 9. The adjusting base 5 includes a joint support, which can adapt to the tilt of the steel gate 10 or the unevenness of the gate bottom plate 11.

[0082] like Figure 15 As shown, in some embodiments, each link 4 includes two end lugs 4-1 and a double-ended screw 4-2;

[0083] Each link 4 is hinged to the corresponding U-shaped rubber waterstop 7-2 and the corresponding steel rod 3-1 through the corresponding two end lugs 4-1 respectively;

[0084] Each of the end lugs 4-1 has an internal thread structure and is connected to the corresponding double-ended screw 4-2 through the corresponding internal thread structure.

[0085] In practical applications, the connecting rod 4, which includes two end plates 4-1 and a double-ended screw 4-2, can be adjusted in length via a threaded connection.

[0086] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
