[0025] Referring to Figures 1 to 3 The application discloses a hidden bottom shaft 2 driving hydraulic dam, which comprises a box body 1, a bottom shaft 2, a driving cylinder 3, a connecting rod 4 and a support arm 5. The bottom shaft 2 is rotatably arranged on a base 8. The driving cylinder 3 is arranged in the box body 1. The first end of the connecting rod 4 is hingedly connected with the piston rod of the driving cylinder 3. The first end of the support arm 5 is fixedly connected with the bottom shaft 2. The second end of the support arm 5 is hingedly connected with the second end of the connecting rod 4. The driving cylinder 3 is arranged in the closed space of the box body 1 and is not eroded by silt and water flow, thereby protecting the driving cylinder. The support arm 5 is welded on the bottom shaft 2 and is hingedly connected with the connecting rod 4. The driving cylinder 3 is horizontally arranged in the box body 1. The driving cylinder 3 is hingedly connected with the connecting rod 4 through a shaft pin. The two ends of the shaft pin are slidably connected with the sliding groove 61 of the guide block 6. The guide block 6 is fixedly arranged on the inner bottom of the box body 1 and is consistent with the movement direction of the piston rod of the driving cylinder. The piston rod of the driving cylinder 3 drives the connecting rod 4 to move, thereby driving the support arm 5 to synchronously move, so that the opening and closing of the gate is realized.
[0026] The box body 1 is further provided with the guide block 6. The guide block 6 is provided with the sliding groove 61. The first end of the connecting rod 4 is slidably arranged in the sliding groove 61. In the movement process of the connecting rod 4, the first end of the connecting rod 4 slides in the sliding groove 61, thereby playing a guiding role and making the movement more stable and reliable.
[0027] The first end of the connecting rod 4 is hingedly connected with the piston rod of the driving cylinder 3 through the shaft pin. The shaft pin is slidably arranged in the sliding groove 61.
