[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] See Figures 1-4A hydraulic dam locking device comprises: a housing 2; a door leaf 1 with a rotating shaft 11 at its bottom; the door leaf 1 is rotatably mounted on the housing 2 via the rotating shaft 11, and the door leaf 1 can rotate around the rotating shaft 11 on the housing 2; a support arm 12, the first end of which is fixedly connected to the rotating shaft 11, and the second end of the support arm 12 extends into the housing 2; a drive mechanism installed in the housing 2, which can push the support arm 12 to swing, thereby driving the rotating shaft 11 to rotate, and finally driving the door leaf to flip; and a limit seat 4 installed in the housing 2, which has a limit hole 41; the support arm 12 can be locked in the limit hole 41, which can lock the position of the dam. After the door leaf 1 swings to the target position, the support arm 12 is locked in the limit hole 41, thereby determining the position of the door leaf 1. At this time, the hydraulic dam can be depressurized, and it is not necessary to maintain high pressure at all times. After the dam is locked, the hydraulic system can be depressurized, which improves the system life.

[0025] The support arm 12 is equipped with a locking cylinder 5, and the piston rod of the locking cylinder 5 is equipped with a locking rod 51, which can extend into the limiting hole 41. The locking cylinder 5 drives the locking rod 51 to extend or retract, thereby entering or disengaging from the limiting hole 41, thus playing the role of limiting or releasing the limit.

[0026] The driving mechanism is a hydraulic cylinder 3, and the piston rod of the hydraulic cylinder 3 is hinged to the support arm 12. The hydraulic cylinder 3 is the main mechanism for driving the movement of the door leaf.

[0027] The housing 2 also has a mounting base 6, on which the drive cylinder 3 is hinged. During the swing of the swing arm, a certain arc will be generated, so the drive cylinder 3 needs to have a certain range of motion. Therefore, the installation method of hinged to the mounting base 6 is adopted.

[0028] The locking cylinder 5 is mounted on the second end of the support arm 12. The piston rod of the drive cylinder 3 is hinged to the support arm 12 near the middle. The drive component is located near the middle, and the locking component is located at the second end.

[0029] With the above structure, the position of the dam body can be locked. After the dam body is locked, the hydraulic system can be depressurized, thus improving the system's lifespan.
