The invention discloses a platform moon pool damping device which comprises a shock absorption cabin and a shake absorption cabin which are arranged on the transverse inner walls at the two ends of a moon pool and separated through a watertight separation board. Multiple rows of damping blocks distributed in a staggered manner are transversely arranged on the outer wall of the shock absorption cabin and the outer wall of the lower portion of the shake absorption cabin respectively. Multiple wave stop columns are arranged on the outer wall of the lower portion of the shake absorption cabin. Three separation boards are arranged in the shake absorption cabin from top to bottom. Multiple rows of vertical wave elimination blocks horizontally distributed in a staggered manner are transversely arranged on the upper sides and the lower sides of the separation boards and the inner wall of the shake absorption cabin bottom. The separation boards are provided with vertically-corresponding wedge blocks towards the outer end of the platform moon pool. Multiple rectangular openings are formed in the shock absorption cabin outer wall and a vertical wall board of the shock absorption cabin respectively. Multiple rows of horizontal wave elimination blocks vertically distributed in a staggered manner are transversely arranged on the inner walls of the two longitudinal ends and a vertical wall board of the moon pool. The shock absorption cabin and the shake absorption cabin can guarantee that a platform works safely and stably under different working conditions. The wave stop columns arranged on the outer wall of the lower portion of the shake absorption cabin can effectively resist incoming flow impact, the kinetic energy of waves is weakened, incoming flow is inducted to move towards the bottom of the moon pool, and formed vortexes in the moon pool are reduced.

The invention discloses a novel assembly type landscape overflow weir, and belongs to the field of overflow weirs. When the novel assembly type landscape overflow weir is used, it is ensured that theoverflow weir has the certain overflow capacity. When the novel assembly type landscape overflow weir is designed, the enough orifice size shape and high flow coefficient are achieved, so that the novel assembly type landscape overflow weir has the enough overflow capacity, the good orifice shape is achieved during designing, water can smoothly flow through the weir, harmful negative pressure, vibration, cavitation erosion and the like are not generated, it is ensured that local scouring damaging the safety of a weir body is avoided at an underwater bed, the position where the overflow weir section is located in the pivot should make the downstream water flowing state be smooth, reflection and scour flow is avoided, and normal operation of other buildings in the pivot is not affected and is in the working process.
