With continued reference to fig. 3, the pontoon 200 of the present invention is hollow in the shape of a bowling pin, and the pontoon 200 includes a large end and a small end 212, the large end is disposed at the tail of the frame 100, and the distance between the large end and the horizontal plane is greater than the distance between the small end 212 and the horizontal plane, so as to ensure that the included angle between the pontoon 200 and the horizontal plane is acute.
It should be noted that, buoy 200 of the present invention is a hollow inflatable balloon, and when in use, buoy 200 should have a certain pressure of gas therein, and when not in use, appropriate venting can be performed. The buoy 200 changes the traditional design mode of a uniform cylinder, adopts a streamline design scheme that the buoy 200 at the front part of the towed raft is small in diameter and the buoy at the rear part of the towed raft is large in diameter, can increase and decrease the resistance of the towed raft in water, can effectively reduce the left-right swing of the tail part of the towed raft in the towing process, and can also shorten the turning time of the towed raft and weaken the roll. The floating center of the towed raft is moved backwards by the design of the appearance structure of the pontoon 200 and the relative position of the pontoon 200 and the frame 100, so that pitching can be effectively reduced.
Meanwhile, as the connectors 220 are arranged at the two ends of the pontoon 200, the height position of the connectors 220 on the short side of the frame plate 110 can be adjusted, and the inclination angle of the axis of the pontoon 200 can be changed, so that the height of the front and back of the axis of the pontoon 200 can be adjusted, the problem that the towed raft tilts forward when the towed raft is static in water due to different diameters of the pontoon 200 can be effectively solved, the stability of the towed raft is further ensured, and the breaking of waves and the reduction of water resistance of the towed raft are facilitated; still, still water can keep the level of the whole towed raft; the floating center of the towed raft moves backwards, so that pitching can be effectively weakened; effectively weakening the roll, and being more agile when turning or turning around.
Preferably, one end of the connector 220 is embedded into the pontoon 200, the other end of the connector 220 is provided with the connecting seat 230, and the connecting stability between the connector 220 and the pontoon 200 is ensured by embedding one end of the connector 220 into the pontoon 200, and meanwhile, the connecting seat 230 at the other end of the connector 220 can effectively facilitate the connection between the pontoon 200 and the frame 100.
With continued reference to fig. 2, the frame plate 110 of the present invention is bent into a rectangular frame shape by stainless steel pipes, and a transverse pipe 120 is disposed in the middle of the frame plate 110, and two ends of the transverse pipe 120 are respectively connected to two short sides of the frame 100, so that the processing is simpler and more convenient, the structure is more stable, and the weight is lighter.
Further, the platform pipes 150 are installed between the transverse pipes 120 of the present invention, at least two platform pipes 150 are installed, and two ends of the platform pipes 150 are respectively connected with the transverse pipes 120 on the two side frames 100, so as to ensure the stability of the structure of the frames 100.
With continued reference to fig. 1, the long sides of the tops of adjacent frames 100 of the present invention are provided with overlapping pipes 130, and a GPS mounting bar 140 is provided between the overlapping pipe 130 and one of the platform pipes 150. The GPS mounting rod 140 is designed to be a telescopic rod shape because the GPS mushroom head has a relatively small mass and volume and the GPS rod does not need to have a large stress intensity. The GPS mounting rod 140 is telescopic and has adjustable height, strong adaptability and convenient work development and implementation.
In the actual use process, the GPS is adjusted according to the actual situation, and the GPS is adjusted to be as low as possible on the premise of ensuring that the GPS signals are stable and are prevented from being polluted by sea water stormy waves, so that the stability of the integral frame 100 of the towed raft is ensured, and the positioning deviation caused by the change of the posture of the towed raft is reduced. The reason that the platform pipe 150 for installing the GPS mounting rod 140 is arranged at one side close to the big end of the pontoon 200 and the GPS is installed at the rear part of the towed raft is that the rear part of the towed raft is closer to the rotation center, the swinging of the towed raft is smaller and the positioning precision is higher; meanwhile, the stress is smaller and safer.
Preferably, another platform tube 150 of the present invention is connected with a flexible rope, and the other end of the flexible rope is externally connected with a side-scanning sound horn.
Finally, the methods of the present application are only preferred embodiments and are not intended to limit the scope of the invention.
