Meanwhile, a plurality of mounting holes or mounting grooves are designed on the floating body, which are used to fix the related equipment on the floating body. However, the fixing method has poor firmness, and the related equipment is prone to looseness due to the fluctuation of the floating body with the sea waves, which may cause the related equipment to be knocked or the signal, power and other transmission lines on the related equipment to be pulled off, thereby causing the related equipment to be unable to use.

[0024] A multi-layer rotational molding hot melt composite floating body, as Figure 1 shown, is usually assembled together to build a sea floating platform, such as a navigation mark floating platform, and the process shape of the composite floating body usually includes a quarter of a circular sector, a half of a semicircle or a cylinder, etc. This embodiment takes a quarter of a circular sector as an example for description, that is, the shape of the composite floating body is in the form of a sector block, so it has a sector-shaped top surface 101 and bottom surface 102, rectangular left side surface 103 and right side surface 104, inner arc surface 105 and outer arc surface 106.
[0025] The composite floating body comprises a hollow shell 11 integrally rotational molded, which is provided with an equipment cabin 3 recessed integrally from the shell surface, that is, the top surface 101 of the shell, and an EPS foamed body 12 filled in the shell 11 and wrapping the equipment cabin 3 by an EPS foaming agent.
[0026] The shell wall of the shell 11 is composed of a first rotomolded PE outer layer 111, a PE foamed middle layer 112 and a rotomolded PE inner layer 113, which has higher use strength than the single-layer shell wall of the traditional floating body, that is, has better crashworthiness and corrosion resistance, so as to avoid collision rupture or weathering rupture and the like in the harsh marine environment and ensure normal use.
[0027] The equipment cabin 3 has a hatch 32 exposed on the surface of the shell 11 and a cover plate 2 covering the hatch, so that when the related equipment is arranged in the equipment cabin 3, the hatch 32 can be covered by the cover plate 2 and hot-melt connected, so as to enclose the related equipment in the equipment cabin 3.
[0028] Obviously, since the related equipment is hidden in the equipment cabin 3 of the floating body, it can be wrapped and protected by the EPS foamed body 12 and isolated from the seawater with strong corrosion, so as to provide better crash protection, corrosion protection and installation firmness for the installed related equipment, thereby prolonging the service life of the related equipment.
[0029] The cover plate 2 is composed of an outer shell 21 and a PU foamed body 22 filled in the outer shell by a PU foaming agent, and the shell wall of the outer shell 21 is composed of a second rotomolded PE outer layer 211 and a PE foamed inner layer 212, which also has higher use strength.
[0030] Meanwhile, the cover plate 2 and the hatch 32 adopt a covering and closing structure of a frustum 23 and a tapered opening, such as a four-pyramid frustum and a four-pyramid opening in this embodiment, and the outer shell 21 at the frustum 23 and the shell 11 at the tapered opening are hot-melt connected into one body, and the covering structure can ensure that the hot-melt after covering is more compact.
[0031] The top surface 101, the left side surface 103 and the right side surface 104 are all provided with a plurality of wire-through holes 31 communicating with the equipment cabin 3, which can be used for connecting various signal and power transmission lines into the equipment cabin 3 to connect the related equipment.
[0032] The shell 11 is provided with mounting holes 4 penetrating the top surface 101 and the bottom surface 102 respectively, and the hole opening of the mounting hole penetrating the top surface is provided with a mounting disc 41, and the top surface of the shell 11 is also provided with a plurality of mounting grooves 6, so that the mounting holes 4, the mounting disc 41 and the mounting grooves 6 can all provide fixed installation of external components on the floating body.
[0033] The left side surface 103 and the right side surface 104 are both provided with a plurality of connecting holes 5, which are used to connect and fix a plurality of composite floating bodies when they are assembled together, so as to build a complete offshore floating platform.
[0034] And, since the single floating body can independently internally dispose the related equipment, even if the related equipment in a certain floating body is damaged, the floating body only needs to be removed and a new floating body with intact equipment is configured, avoiding the trouble that the whole offshore platform must be towed away and the related equipment must be disassembled and replaced in the traditional way, so that the disassembly and replacement process is more convenient.
[0035] The above is only a specific embodiment of the present application, and those skilled in the art should understand that any equivalent structural design of the embodiment should be included in the protection scope of the present application.
