In this embodiment, the projection mechanism further includes a support plate 235 and two support rods 236, the support plate is disposed between the bottom plate and the sliding plate, and the support plate is fixedly connected to the telescopic rod. The telescopic ends of the two second cylinders are respectively connected with one ends of the two abutting rods, and the other ends of the abutting rods are fixedly connected with the abutting plates, so that the abutting plates are driven to move through the second cylinders, and then the telescopic rods are driven to move towards one end direction along the other end of the first support. In this embodiment, the up end of first support still is equipped with two spacing seats, two spacing seat is located respectively between bottom plate and the slide and arranges the setting in proper order along the axial of telescopic link, be equipped with on the spacing seat with the spacing hole of the coaxial setting of telescopic link, the aperture in spacing hole is 32mm, the diameter of telescopic link is 30 mm. Realize the spacing of telescopic link motion process through spacing seat, simultaneously, the aperture in the spacing hole of spacing seat is 32mm, and the diameter of telescopic link is 30mm, can guarantee through spacing seat that the telescopic link is the biggest offset when the motion by spacing within 2mm, can throw the fishing net to the outside when can guaranteeing thrust on the telescopic link to act on the fishing net.

In this embodiment, first connecting hole is close to the drill way end of contact pin is equipped with V type spigot surface, plays the guide effect to inserting of contact pin, is convenient for the contact pin to insert in first connecting hole.

In this embodiment, still be equipped with second motor 211 on the base, the lower terminal surface of the other end of frame is equipped with the second pivot, the one end of second pivot simultaneously with first support and second shelf fixed connection, the other end of second pivot is connected with the drive shaft transmission of the second motor on the base, drives through driving the second motor the frame is rotatory along the horizontal direction to can adjust the casting direction of fishing net.

In this embodiment, the outer side wall of the power assisting ring is provided with more than two fan blades which are equidistantly distributed along the circumference, an inclined angle is formed between a plane perpendicular to the axial direction of the power assisting ring and a plane where the fan blades are located, the angle range of the inclined angle is 10-30 degrees, the radius of the power assisting ring is 25cm, and the radius of the fan blades is 8 cm. The outer side wall of the power assisting ring is provided with more than two fan blades which are distributed at equal intervals along the circumference, and the rotating centrifugal force of the power assisting ring is increased by the fan blades of the power assisting ring when the fishing net is thrown.

In this embodiment, the slide is close to and is kept away from be equipped with the spring rubber pad on the terminal surface of telescopic link one end. The ejection function of the sliding plate can be increased.

Referring to fig. 1 to 4, a second embodiment of the present invention is: the difference with the first embodiment is that the hinge structure of the balance mechanism is further improved, specifically: the first annular frame and the second annular frame and the supporting plate are hinged through pin shafts. The hinge pin has a large axial moving angle range, and is suitable for fishing boats in high-storm environments such as a sea fishing boat and the like.

In summary, according to the fishing net casting device based on the fishing boat provided by the invention, the opposite ends on the outer side wall of the second annular frame are hinged with the inner side wall of the first annular frame, the opposite ends on the outer side wall of the support plate are hinged with the inner side wall of the second annular frame, the connecting lines of the hinged parts of the opposite ends on the outer side wall of the second annular frame are perpendicular to the connecting lines of the hinged parts of the opposite ends on the outer side wall of the support plate, the connecting lines of the mutually perpendicular hinged parts are respectively arranged corresponding to the transverse direction and the longitudinal direction of the hull of the fishing boat, and the fishing boat can be enabled to keep balance when swinging independently of the support plate through the hinged structure. And the fishing net casting device is erected on the supporting plate, the gravity center of the fishing net casting device and the gravity center of the supporting plate are located on the same vertical line, so that the fishing net casting device and the balancing plate can be balanced together, the fishing net casting device is guaranteed to have a stable working environment when the fishing net is cast, and the fishing net can be smoothly cast to the outside along a preset casting angle.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent changes made by using the contents of the present specification and the drawings, or applied directly or indirectly to the related technical fields, are included in the scope of the present invention.
