Portable water surface duckweed fishing net rack
The invention provides a portable water surface duckweed fishing net rack and an operation method thereof. The portable water surface duckweed fishing net rack comprises a plurality of supporting rodscapable of stretching and retracting transversely and relatively, wherein a connecting rod is hinged to the outer end of the supporting rod positioned on the outermost side; the supporting rods can be overturned by 90 degrees relatively; a groove capable of containing the connecting rod is formed in the side, opposite to the connecting rod, of each supporting rod; L-shaped supporting frames are arranged on the two sides of the connecting rod; the two supporting frames are connected through a back net and a bottom net; each supporting frame is composed of a first supporting rod and a second supporting rod; the ends of the first supporting rods and the ends of the second supporting rods are hinged; side nets are connected between the first supporting rods and the second supporting rods; anda fishing net is formed by the back net, the bottom net and the bottom net. According to the portable water surface duckweed fishing net rack and the operation method thereof, the supporting rods capable of stretching and retracting relatively, the first supporting rods and the second supporting rods are arranged, the first supporting rods and the second supporting rods are connected with the side nets, the back net and the bottom net, the first supporting rods and the second supporting rods can be folded into the grooves formed in the supporting rods relatively and are tightened through pullropes, and therefore the fishing net rack can be folded and unfolded, and carrying and placing are facilitated.
本发明提供一种便携式水面浮萍打捞网架及其操作方法，包括多个可相对横向伸缩的支撑杆，位于最外侧的一支撑杆外端部铰接有连杆，可相对进行90°翻转，每个支撑杆相对连杆一侧均开设有可容置连杆的凹槽，所述连杆的两侧设有呈L形的支撑架，两个支撑架之间通过背网和底网相连，所述支撑架由两个端部相铰接的支杆一和支杆二组成，支杆一和支杆二之间连接有侧网，所述背网、底网和底网形成一打捞网。该便携式水面浮萍打捞网架及其操作方法，设置可相对伸缩的支撑杆，以及连接有侧网、背网、底网的支杆一和支杆二，支杆一和支杆二可相对收拢至支撑杆上开设的凹槽内，并通过拉绳进行束紧，从而实现打捞网架的收拢、展开，便于携带放置。
