Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Example: Please refer to Figures 1 to 5 :
[0026] The utility model proposes an automatic fishing device for a lifeboat, comprising: a pulling rope 1 with a signal transmission function, the upper end of the pulling rope 1 is connected to a rope winding device with a signal technique function; a fishing lifting head 2, the upper end of the fishing lifting head 2 is fixedly connected with a rope ring 2-1, and the pulling rope 1 is connected to the fishing lifting head 2 through the rope ring 2-1; a plurality of groups of fishing claws 3 are hinged at the bottom of the fishing lifting head 2; a fishing clamp head 4, the fishing clamp head 4 is fastened to the corresponding part of the upper part of the lifeboat, the fishing clamp head 4 is vertically upward, a limit block 2-2 with a trapezoidal structure is fixedly connected at the bottom of the fishing lifting head 2, a group of ear plates 2-3 are fixedly connected to the left and right sides of the lower surface of the fishing lifting head 2, a pin shaft 2-4 is fixedly connected to the ear plate 2-3, and a signal transmitter 2-5 is fixedly connected to the middle of the lower surface of the limit block 2-2.
[0027] In the embodiment of the present disclosure, a hinge hole is opened at the upper end of the multiple groups of fishing claws 3, and the hinge hole is rotatably connected to the pin shaft 2-4. The lower end of the multiple groups of fishing claws 3 is bent and processed to have a fishing claw frame 3-1 with a hook-shaped structure. The fishing claw frame 3-1 is bent and arranged toward the center direction of the fishing lifting head 2. The end of the fishing claw frame 3-1 is fixedly connected to a lifting head 3-2 with a spherical structure. The fishing claw frame 3-1 is made of non-magnetic material, and the lifting head 3-2 is made of magnetic metal material. By setting the limit block 2-2, the retraction angle of the multiple groups of fishing claws 3 is limited, so that the inner surface of the multiple groups of fishing claws 3 fits with the bevel of the limit block 2-2 and cannot shrink inward excessively.
[0028] In the disclosed embodiment, a signal receiver 4-1 is fixedly connected to the middle of the upper surface of the fishing clamp head 4, and the two side edges of the upper half of the fishing clamp head 4 are lowering guide surfaces 4-2 with an inclined structure, and the two side edges of the lower half of the fishing clamp head 4 are lifting guide surfaces 4-3 with an inclined structure. The outer surface of the lifting guide surface 4-3 is covered with a high-strength magnet 4-4, and a fishing socket 4-5 with a semicircular groove structure is provided at the upper end of the lifting guide surface 4-3. A semicircular transition head 4-6 is processed at the connection between the fishing socket 4-5 and the lowering guide surface 4-2. The curvature of the fishing socket 4-5 is consistent with the curvature of the lifting head 3-2. The fishing clamp head 4 is tightly connected to the corresponding part of the upper part of the lifeboat, so that the fishing clamp head 4 is always in a vertical upward state.
[0029] In the disclosed embodiment, the lifting guide surface 4-3 and the fishing socket 4-5 are both made of magnetic metal materials, and the remaining parts are all made of non-magnetic materials. The components of the fishing clamp head 4 all have the function of signal transmission; through the action of the high-strength magnet 4-4, the lifting head 3-2 is attracted, so that the fishing claw frame 3-1 is retracted inward and enters the fishing socket 4-5, and the lifting heads 3-2 on both sides are inserted into the fishing socket 4-5 to clamp the fishing clamp head 4, so that multiple groups of fishing claws 3 can lift the fishing clamp head 4 and move it upward.
[0030] The working principle of this embodiment is as follows: when the lifeboat completes the rescue mission, the device receives the lifeboat recovery signal, the automatic control device sends a release signal to the rope winding device, the rope winding device works, the pulling rope 1 drives the fishing lifting head 2 and the multiple fishing claws 3 to be released downwards, and at the same time, the signal transmitter 2-5 installed on the fishing lifting head 2 transmits a wireless positioning signal, so that the signal receiver 4-1 installed on the fishing clamp head 4 receives the wireless positioning signal, and drives the lifeboat to move below the fishing lifting head 2. As the multiple fishing claws 3 are continuously lowered, the lifting head 3-2 and the fishing claws 3 are lowered. The upper end of the fishing clamp head 4 is in contact with each other. Under the gravity of the fishing lifting head 2 and the damping effect of the lowering guide surface 4-2, the lifting head 3-2 drives the multiple groups of fishing claws 3 to open and move downward along the lowering guide surface 4-2. When the lifting head 3-2 passes over the transition head 4-6, the multiple groups of fishing claws 3 quickly return to their original positions under the gravity and the magnetic force of the high-strength magnet 4-4. The lifting head 3-2 is firmly adsorbed on the lifting guide surface 4-3 under the magnetic force of the high-strength magnet 4-4, and a magnetoelectric signal is generated between the lifting head 3-2 and the lifting guide surface 4-3. The magnetoelectric signal is transmitted upward to the fishing lifting head 2 through the multiple groups of fishing claws 3, and the fishing lifting head 2 is transmitted upward to the pulling rope 1, and the pulling rope 1 is transmitted upward to the automatic control device. After receiving the signal, the automatic control device sends a recovery signal to the rope winding device, and the rope winding device reverses to reel in the pulling rope 1. The pulling rope 1 drives the fishing lifting head 2 and the multiple groups of fishing claws 3 to lift upward. Under the action of its own gravity and the magnetic force of the high-strength magnetic 4-4, the lifting head 3-2 is firmly adsorbed on the lifting guide surface 4-3 and slides upward along the lifting guide surface 4-3. When the lifting head 3-2 slides upward to the fishing socket 4-5, under the clamping action of the fishing socket 4-5 and the overtravel transition head 4-6, as well as the action of its own gravity and the magnetic force of the high-strength magnet 4-4, the lifting head 3-2 is firmly fixed to the fishing socket 4-5, and the pulling rope 1 drives the fishing lifting head 2 and the fishing claw 3 to continue to lift upward. At the same time, the fishing claw 3 drives the fishing clamp head 4 to lift upward, and the fishing clamp head 4 drives the lifeboat to lift upward until it is lifted to the set position. The lifeboat automatic fishing device completes the automatic fishing of the lifeboat;
[0031] During the automatic fishing process, there is inevitably a position deviation between the fishing lifting head 2 and the fishing claws 3 and the fishing clamp head 4. The signal transmitter 2-5 of the fishing lifting head 2 continuously transmits a wireless positioning signal, and the fishing clamp head 4 receives the wireless positioning signal through the signal receiver 4-1 and continuously drives the lifeboat to adjust the relative position of the fishing clamp head 4 and the fishing lifting head 2 and the fishing claws 3; when the lifting heads 3-2 on multiple groups of fishing claws 3 are not all in contact with the upper end of the fishing clamp head 4, the lifting heads 3-2 will transmit signals to the automatic control device, and the automatic control device will send signals to the rope winding device, which will drive the operation so that the pulling rope 1 drives the fishing lifting head 2 and the fishing claws 3 to lift upward a certain distance, and then the lower rope is lowered to re-fish until the lifting heads 3-2 are all in contact with the upper end of the fishing clamp head 4, and the fishing work continues.
