Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, light-duty fishing underwater foreign matters device of the present invention is described in further detail.
As shown in Figure 1, a kind of fishing underwater foreign matters device of the present invention comprises bracing frame 1, is arranged on the submersible motor 3 in bracing frame 1 and immersible pump 4, and immersible pump 4 one end is connected with submersible motor 3, and immersible pump 4 other end is connected with collecting pipe 5.This immersible pump 4 is two-way immersible pump, can carry out rotating and multi-gear transmission running, submersible motor 3 can make immersible pump 4 rotate forward or reversely rotate, inside and outside collecting pipe 5 mouthfuls, form two-way water pressure difference, suction of foreign body during forward running, is discharged into foreign matter in foreign matter accommodating container during antiport.Submerged cable 2 is connected with submersible motor 3.
As shown in Figure 2 or Figure 3, collecting pipe 5 comprises the tube connector 6 and collection mouth 11 or 12 that are connected, and it is inner that filter screen 7 is arranged on tube connector 6.Described collection mouth is the occasion that straight type collection mouth 11 or flexure type collection mouth 12(flexure type are drawn for side direction).Tube connector 6 one end of collecting pipe 5 is connected by securing member and rapid replacing interface with bracing frame 1; Tube connector 6 other end is connected by connecting plate 10, latch assembly 8 and slip-knot buckle ring 9 with collection mouth 11 or 12, to unclamp tube connector 6 and to collect mouth 11 or 12, quick-replaceable filter screen 7.
