Description

Double-layer composite plastic floating body

Technical Field

The utility model belongs to plastics body field, in particular to double-deck compound plastics body.

Background

The existing common self-floating body is generally a plastic floating body, a rubber floating body and a steel box body floating body, and the plastic floating body has the characteristics of light weight, convenient transportation and the like, so the plastic floating body is widely used; however, the plastic floating body has many disadvantages, such as not very strong strength, large water resistance, easy aging after being irradiated by long-time sun, easy breakage in low temperature environment, corrosion of the surface layer of the bottom to a certain extent even if the bottom is soaked in water for a long time, etc., although the existing plastic process can solve the problems caused by plastic raw materials, when the surface layer of the shell of the plastic floating body is cracked, the plastic floating body is immersed in water due to the defects of the structure, so that the buoyancy of the floating body is insufficient, the plastic floating body sinks or even influences the plastic floating bodies on both sides; in order to prolong the service life of the plastic floating body and reduce the condition that the plastic floating body enters water due to the damage of the surface of a shell of the plastic floating body, the double-layer composite plastic floating body is provided.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a double-deck compound plastics body solves the problem that the plastics body that leads to intakes because plastics body shell surface is damaged.

The utility model adopts the following technical scheme:

a double-layer composite plastic floating body comprises an upper floating body and a lower floating body, wherein the upper floating body and the lower floating body have the same structure; the upper floating body comprises a shell surface layer, a compartment is arranged below the shell surface layer, a second shell layer is arranged below the compartment, a foam filling layer is arranged in the second shell layer, two arc surface grooves are formed in the arc surface of the upper floating body, semicircular grooves are formed in the connecting contact surfaces of the upper floating body and the lower floating body, and positioning holes and positioning keys are formed in the connecting contact surfaces of the upper floating body and the lower floating body.

Furthermore, the foam filling layer is made of high-strength polyurethane foam material, has the characteristics of low water absorption rate, aging resistance, high temperature resistance and the like, and is suitable for the requirements of the plastic floating body.

Furthermore, the surface layer of the shell is made of medium density polyethylene, so that the plastic floating body has good environmental stress cracking resistance and long service life, and the service life of the plastic floating body can be prolonged.

Furthermore, the positioning hole and the positioning key are circular, so that preliminary positioning is facilitated during installation.

Further, be equipped with the spread groove on the last floating body, the spread groove is equipped with 6, be equipped with the bolt hole on the spread groove, the installation and the fixed of the bolt of being convenient for.

Further, the upper floating body and the lower floating body are fixedly installed through bolts.

The utility model has the advantages that: when the surface layer of the shell of the plastic floating body is broken or corroded by liquid water, the liquid water cannot immediately fill the interior of the plastic floating body, so that the floating body rapidly sinks, and because the double-layer composite plastic floating body is provided with a plurality of compartments below the surface layer of the shell, the liquid water only contacts two wall surfaces and a second shell layer of the compartments and cannot directly enter the plastic floating body to further corrode a foam filling layer in the plastic floating body, under the condition, the double-layer composite plastic floating body still can keep relatively good buoyancy, and the influence on the plastic floating bodies on two sides is small; the service life of the plastic floating body can be greatly prolonged by adopting the double-layer composite plastic floating body.
