DETAILED DESCRIPTION

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0035] like Figure 1 As shown, the technical solution of the present invention provides a multifunctional tail platform for a small boat, comprising:

[0036] The platform plate 1 is welded to the stern sealing plate of the boat body and the platform outer plate. The platform plate 1 is a horizontal platform and is corner-jointed with the stern sealing plate 12 of the boat body and the platform outer plate 13.

[0037] The platform outer plate 13 is welded to the outer plate of the boat body, including the fender 11. The platform outer plate 13 is inclined laterally along the line of the outer plate 14 of the boat body, gradually widens from the rear end and butts with the outer plate 14 of the boat body;

[0038] A strong frame, including longitudinal girders and strong transverse beams, is arranged on the back of the platform plate 1;

[0039] The stiffeners, including longitudinals and transverse beams, are arranged on the back of the platform plate 1 and the platform outer plate 13;

[0040] The strong frame and reinforcing ribs constitute the rear platform reinforcement structure.

[0041] The tail platform is located between the propeller 10 and the main deck 9 of the small square tail aluminum alloy boat, and is welded and installed on the tail sealing plate 12 of the boat body. The strength of its structure is determined according to the relevant regulations of China Classification Society and the actual loading load. Figure 1 As shown in the figure, the tail platform structure is composed of platform plate + platform outer plate + strong frame (longitudinal girder / strong transverse beam) + reinforcing ribs (longitudinal bone / transverse beam) + bracket and other structures. When the tail platform structure of a small square tail boat is a platform plate + platform outer plate + longitudinal / transverse girder + frame and other structures and outfitting equipment, it can ensure the structural strength requirements, have a safe structural structure and take into account the overall beauty of the boat, and have multiple functions including observation / simple maintenance / protection of propellers, wave suppression, escape, and leaning on help.

[0042] In one embodiment of the present invention, the tail platform structure is an aluminum alloy welded structure, the length of which covers and exceeds the tail end of the propeller 10, and the maximum width does not exceed the width of the tail sealing plate 12 of the boat body. By designing the platform outer plate of the tail platform to gradually increase in width from the tail end to the head end, and to connect with the outer plate in a transversely inclined manner along the entire ship type line, and reinforcing ribs are arranged on the bottom or inner surface, it is visually more coordinated with the boat body and more beautiful than a small platform.

[0043] like Figure 1 As shown, in one embodiment of the present invention, the tail platform structure is an aluminum alloy welded structure, the length covers and exceeds the tail end of the propeller, the maximum width does not exceed the width of the tail seal plate, and the outer side is inclined 1° from the tail seal plate to the centerline of the hull. By designing the tail platform to be the width of the entire ship and inclining 1° from the tail seal plate to the centerline of the hull, the tail platform has the maximum width space without exceeding the width of the boat type. Compared with a small platform, more outfitting equipment can be arranged, which is more conducive to the safety of personnel operations.

[0044] like Figures 1 to 3 As shown, in one embodiment of the present invention, the span of the strong cross beam at the rear end of the platform plate 1 is equal to the width of the rear platform, a life raft 3 is arranged above the middle part, which has sufficient strength, and the reinforcement ribs at the lower end are hidden at the bottom of the platform plate 1.

[0045] like Figures 4 to 5As shown, in one embodiment of the present invention, the platform plate 1 is provided with a horizontal girder facing the back of the stern sealing plate, the longitudinal girder under the platform plate 1 is provided with a vertical girder facing the back of the stern sealing plate, and other longitudinal bones corresponding to the platform plate 1 are provided with vertical reinforcement ribs facing the back of the stern sealing plate. By arranging the platform plate of the stern platform and the longitudinal reinforcement structure below it to the structure on the back of the stern sealing plate and welding them to the stern sealing plate, and connecting the platform outer plate 13 with the outer plate 14 of the main body of the boat in a continuous manner, the platform load can be effectively dispersed and transferred to the main body outer plate and the stern sealing plate frame structure, which has better structural strength and is safer and more reliable than the pillar support of the small platform.

[0046] like Figures 6 to 8 As shown, in one embodiment of the present invention, the platform outer plate and reinforcing rib combination structure on the outside of the tail platform is the most important longitudinal support structure and should have sufficient strength. In addition, the platform outer plate 13 is inclined laterally along the line of the boat body outer plate 14, gradually widens from the tail end and docks with the main body outer plate, and a circular chamfer is set at the mutation point; the part of the combined structure above the plane of the platform plate 1 can be directly used as the installation surface of the boarding ladder and handrail, and the ladder is prevented from being exposed; all reinforcing ribs are hidden on the back of the platform outer plate and are not exposed, forming an "L" shape.

[0047] like Fig. 9 As shown, the platform plate 1 is provided with a propeller observation hole 2 just above the propellers 10 on the port and starboard sides. In this embodiment, the observation hole 2 is 400 mm x 300 mm in size and is equipped with a simple aluminum cover plate, which is ensured to be fixed when not in use.

[0048] like Figures 9 and 10 As shown, a pad is provided on the platform plate 1, and various outfitting parts are provided on the pad. In this embodiment, the tail platform is equipped with outfitting parts such as stainless steel railings 4, life rafts 3, aluminum steps 5, stainless steel plastic-coated handrails 6 and aluminum alloy railings 7. After the pad is installed on the platform, each outfitting part or outfitting part mounting bracket is welded to the pad. The stainless steel railing 4 extends to the bulwark 8. By arranging the propeller observation hole 2, stainless steel / aluminum alloy railings, stainless steel plastic-coated handrails, aluminum steps, life rafts and other outfitting equipment on the tail platform, compared with the single function of a small platform, it can have multiple functions such as observation / simple maintenance of the propeller, wave suppression, escape, etc.

[0049] like Figures 9 and 10 As shown, in addition to providing a small boat multifunctional stern platform, the technical solution of the present invention further provides a small boat, which is provided with the above-mentioned small boat multifunctional stern platform.

[0050] The above are preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
