This invention discloses a variable cross-sectional area friction-electromagnetic composite power generation raft buoy and method, solving the problems of low power generation efficiency caused by the non-adjustable natural frequency and mismatch between the optimal operating frequencies of TENG and EMG in existing wave energy buoys. This invention dynamically adjusts the raft width through a symmetrically arranged variable cross-sectional area mechanism, enabling the natural pitch frequency to track common ocean wave frequencies of 0.5Hz-2Hz in real time, achieving broadband resonance energy capture. It innovatively designs a dual-path transmission module, simultaneously decomposing the same wave pitch motion into a low-frequency extension motion matching the TENG and a high-frequency linear motion matching the EMG, allowing both to operate within their peak efficiency range. Hydraulic transmission is used to transfer mechanical energy, and multiple buoys can be quickly hinged together to form an expandable power generation array. This invention improves wave energy capture efficiency by more than 3 times across all sea states and increases total power generation by more than 60%, making it suitable for self-powering distributed equipment such as ocean buoys, observation stations, and underwater sensors.

This invention relates to a pontoon unit (2) for use in a lake, pool or corresponding water area, preferably interconnected with one or more other pontoon units (2) to form a pontoon (2), comprising a buoyancy body (20) and an upwardly facing support surface (2A) for carrying a load, wherein said pontoon unit (2) is circumferentially enclosed by an attachment base (3) that is integrated with the pontoon unit (2) by means of a covering flexible layer (22), wherein said attachment base (3) comprises a plurality of interconnected base members (3A, 3B), each comprising an attachment face (340, 341) arranged to attach connecting member / s (40, 41, 43, 44) for connecting two neighboring pontoon units (2) to each other, wherein at least one of said frame members (3A, 3B) includes an attachment structure (300) having two parallel walls (305, 306) extending vertically a distance (H3) that is greater than the horizontal distance (W3) between said walls (305, 306) and at least one horizontally extending attachment channel (302A, 302B) which is integrated in a bridging member (303) that forms a bridge between said two walls (300, 301).

This utility model discloses a water collection device for rivers in industrial areas, comprising a pump box, an inlet pipe, an outlet pipe, and a water storage tank, as well as a floating raft. The pump box is suspended below the floating raft by a suspension device. The inlet and outlet pipes are connected to the inlet and outlet ends of the pump box, respectively. The outlet pipe is connected to the water storage tank, which is installed at the bottom of the floating raft. This utility model, through its floating and decorative structures, can be concealed at river mouths for water collection at all times. It requires no personnel for collection; only the water storage tank needs to be removed. Furthermore, it can collect water at night, thus detecting any illegal nighttime discharge.
