Embodiment 1

[0038] like figure 1 , figure 2 The hull protective structure of a fishing boat shown includes first protective plates arranged on the upper parts of both sides of the hull, a plurality of first protective strips arranged on the outside of both sides of the hull, and second protective plates arranged on the upper parts of both sides of the bow , a plurality of second protective strips arranged on both sides of the bow and a protective frame arranged at the stern,

[0039] The first protective plate is horizontally and fixedly arranged on the hull, and a plurality of the first protective strips are arranged vertically in a strip shape and evenly distributed under the first protective plate. The first protective strips are arranged from top to bottom. A plurality of embedding grooves are vertically distributed, and a bullet block is embedded in the embedding groove, and the shape and size of the bottom of the bullet block correspond to the internal shape and size of the embedd...

Embodiment 2

[0051] Compared with embodiment 1, the differences of this embodiment are:

[0052] like Figure 12 As shown, the top of the fishing net salvage rack is provided with a square ring body, and the cross section of the square ring body is circular; both sides of the square ring body are fitted with a rolling ring, and the rolling ring and the square ring Bearings are arranged between the bodies, and rolling grooves are set on the side of the rolling ring. The fishing net passes through the square ring body, and the fishing net is salvaged with the fishing net fishing frame as the focus point. In the rolling groove, the rolling ring is rollingly connected with the square ring body when the fishing net rope is dragged.

[0053] The working process of the present invention:

[0054] (1) When the fishing boat is not in use, the protective frame is placed inside the stern, and the protective frame is fixed in the fishing boat through the connection structure between the protective f...

Abstract

The invention discloses a boat body protection structure of a fishing-boat. The structure comprises first protection plates on the upper portions of the two sides of a boat body, multiple first protection strips arranged on the outer portions of the two sides of the boat body, second protection plates arranged on the upper portions of the two sides of a boat head, multiple second protection stripsarranged on the outer portions of the two sides of the boat head, and a protection frame arranged on the boat tail. The first protection strips are vertically provided with embedded grooves in a distributing manner from top to bottom, elastic blocks are embedded in the embedded grooves, one side of the top of the protection frame is connected with one fixed plate through a hinge, the other side of the fixed plate is rotatably connected with a side plate of the boat tail through a hinge, the protection frame is movably connected with the boat tail through the fixed plate, and movable placing inside and outside the side plate of the boat tail can be achieved; the first protection plate, the second protection plate, the second protection strips and the second protection strip structure are arranged, the wear of the boat head and the outer side of the boat body can be effectively avoided, the elastic blocks are arranged on the first protection strips, the possibility of the wear caused bycollision of the wharf and the water edge side can be effectively avoided, the protection frame is adopted, the boat tail is protected, and impact or wear can be avoided.

Description

technical field [0001] The invention relates to a hull protection structure of a fishing boat. Background technique [0002] The outer surface of FRP fishing boats is FRP. FRP has the advantages of low density, high specific strength, easy forming, smooth surface, low water absorption, low thermal conductivity, seawater corrosion resistance, no insects, easy maintenance and repair, etc. It is used for construction The fishing boat can reduce the weight of the hull by 20% to 30%, increase the loading capacity of the fishing boat, reduce resistance, increase the speed, save fuel, and improve economic benefits. [0003] However, the wear resistance of FRP fishing boats is poor. FRP fishing boats often encounter floating objects in the water body during use, and will also rub against the wharf or shore when docking, so the hull is prone to wear and tear. [0004] In addition, during the use of FRP fishing boats for fishing, it is often necessary to drag fishing nets or net rope...
