Embodiment 1
[0021] (1) floating rafts 18 are arranged along the length direction of the pond, and the length is half of the length of the pond. Floating raft 18 is made of the polyvinyl chloride pipe 6 of diameter 4 centimetres, and a floating raft 18 is generally connected to each other by many 4 meters long polyvinyl chloride pipes 6, and every row is 5, forms 4 row and puts the box fence of crab box 5 ( The width is exactly the field of view at a glance). The two ends of the polyvinyl chloride pipe 6 cover the polyvinyl chloride cap 4 to prevent water from entering. The length of the floating raft 18 depends on the length of the pond. The floating raft 18 is divided into small units of 110 x 110 cm each, bound and connected by a narrow piece of wood (2.5 cm wide x 2.0 cm thick x 110 cm long), or the wood is replaced by a small polyvinyl chloride pipe with a smaller diameter than the main pipe . A piece of wood or a small tube is tied horizontally to the main tube. Each part (sectio...

Embodiment 3
[0035] (1) floating rafts 18 are arranged along the length direction of the pond, and the length is half of the length of the pond. Floating raft 18 is made of the polyvinyl chloride pipe 6 of diameter 7 centimetres, and a floating raft 18 is generally connected with each other by many 4 meters long PVC pipes 6, and every row is 5, forms 4 row and puts the box rail of crab box 5 (the width just A glance past the field of view). Polyvinyl chloride pipe 6 two ends cover polyvinyl chloride cap 4, to prevent water from entering. The length of the floating raft 18 depends on the length of the pond. The floating raft 18 is divided into small units of 110 x 110 cm each, bound and connected by a narrow piece of wood (2.5 cm wide x 2.0 cm thick x 110 cm long), or the wood is replaced by a small polyvinyl chloride pipe with a smaller diameter than the main pipe . A piece of wood or a small tube is tied horizontally to the main tube. Each part (section) separated by wood can accommod...
