The utility model relates to technical field of triangular frame, especially a triangular frame convenient for standardizing pendulum ball, it is mainly aimed at the problem that the traditional triangular frame is not standard and the ball gap is uneven because the three inner fillet radius is greater than the ball radius and the triangular frame inertia is pushed by manpower or the pendulum ball is pushed by hand, and the following technical scheme is proposed: including triangular frame body, the push board of setting in one side of triangular frame body, two groups of difference mechanism, two groups of difference mechanism are installed in the other two side surfaces of triangular frame body respectively, difference mechanism includes the recess that is opened in the outside of triangular frame body, the recess is slidably connected with button, the connecting rod is installed to button near one side of triangular frame body, the connecting rod penetrates triangular frame body and is fixedly connected with extrusion board, spring is installed to the outer ring of connecting rod and is covered. The utility model can eliminate the ball gap, improve the pendulum ball compactness and standardization, guarantee the fairness and ornamental of competition, improve the pendulum ball efficiency and precision.

This invention discloses a seawater treatment system for aquatic organism seedling and larval cultivation based on a natural ecological cycle. The system includes a natural sedimentation tank, a secondary sedimentation algae cultivation tank, a multi-stage dark sedimentation tank, a primary sand filter, a secondary sand filter, and a water storage tank connected to the end of the secondary sand filter. A pump is installed to connect to a water storage tower. A seawater concentration device and an ultrafiltration device are also included between the water storage tower and the aquatic organism seedling tank. The secondary sedimentation algae cultivation tank can be directly connected to a juvenile shellfish rearing tank for direct use in juvenile shellfish cultivation. The sand filter also features a backwashing design for easy recycling. The seawater processed through the primary and secondary sand filters, concentration device, and ultrafiltration device can be used for larval cultivation of aquatic organisms. This water treatment system, through its multi-stage structural design and combined with natural environmental control of light and shading, avoids the drawbacks of chemical and biological purification and the shortcomings of simple physical sand filtration in a natural and ecological way. This ensures a large-scale supply of water for aquatic organism seedling and shellfish cultivation, meeting the diverse needs of large industrial areas.
