Abstract

The present invention relates to a buoy having double pipes, which comprises two pipes on an outer side and an inner side, thereby preventing condensation caused by temperature difference and exhibiting enhanced durability. The buoy is formed by a pair of covers integrally coupled on both sides of a body. The body comprises: an outer pipe; and an inner pipe integrally formed on an inner side of the outer pipe wherein a plurality of barriers are radially formed at regular intervals between the outer pipe and the inner pipe. Accordingly, due to a double structure of the outer pipe and the inner pipe, and a first space and a second space, the temperature difference between the outside and the inside may be minimized, thereby preventing condensation, and thus, moisture is not generated from an inner side of the buoy, thereby preventing deterioration of buoyancy. In addition, the outer pipe and the inner pipe are firmly supported by a double pipe structure and the plurality of barriers, and thus, durability of the buoy is enhanced and service lifespan of the buoy is extended, thereby being easily repaired and maintained and being remarkably economic.

Description

{Float made of a double pipe}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an artificial limb made of a synthetic resin for use in a cage farm, and more particularly, to a limb made of a double pipe which is made of two outer and inner pipes to prevent condensation due to temperature difference, .

Generally, a frame is connected in a square shape to a cage and a sea farm where a fish is harvested by using a net in the ocean, and a cage network in which a lower part is located at a lower part of the frame at the lower part of the square- The frame is connected to the lower part of the frame to prevent the frame from sinking to the lower part of the water surface.

However, in the past, when the frame is made of styrofoam which can not be recycled because it does not rot, the styrofoam pieces are piled up on the beach or floated on the shore , There is a problem that the natural environment is destroyed at the time of disposal.

Conventionally, in order to solve the above-mentioned problems, a buoyancy which gives a buoyancy to a frame is made of UV-coated high density polyethylene or high strength rubber pipe, urethane or FRP, And recycling is carried out at the time of discarding the bag.

In Registration Utility Model No. 20-0448065, as shown in Fig. 1, the watertightness is improved, and thus, a bill for maintenance can be saved.

The first and second bodies 1 and 2 are coupled to each other by means of a coupling hole 3, and the first body 1 and the second body 2 are coupled to each other. And a rope connecting body 5 is formed on the outer side.

However, since such a buoy is formed as a single layer, condensation occurs due to the temperature difference between the inside and the outside, so that the moisture gradually gets inward to weaken the buoyancy.

In addition, since durability corresponding to an external force such as ultraviolet rays and waves is low, maintenance is difficult because of frequent replacement.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a double pipe which is composed of two pipes, namely, an outer pipe and an inner pipe, to prevent condensation due to a temperature difference.

It is another object of the present invention to provide a dual port pipe with improved durability and easier maintenance.

In the second aspect of the present invention, there is provided a unit comprising a pair of covers integrally coupled to both sides of a body, wherein the body comprises an outer pipe and an inner pipe integrally formed on the inner side of the outer pipe And a plurality of partition walls are radially formed between the outer pipe and the inner pipe.

According to the present invention, it is possible to prevent the condensation phenomenon by minimizing the temperature difference between the outside and inside by the double pipe structure of the outside pipe and the inside pipe, and the first and second spaces. Moisture is not generated on the inner side of the valve body, and the buoyant force is prevented from being weakened.

Further, in addition to the double pipe structure, the plurality of partition walls firmly support the outer pipe and the inner pipe, thereby improving durability and extending service life, thereby facilitating maintenance and economizing.

Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 2, the mouth of the double pipe of the present invention includes a cylindrical body 100 and a pair of covers 200 integrally coupled to both sides of the body 100.

The body 100 includes an outer pipe 10 and an inner pipe 20 formed on the inner side of the outer pipe 10. The cover 200 includes an outer hemisphere 60, And the inner hemisphere 70 formed on the inner side of the sphere 60 so that the distance between the outer pipe 10 and the inner pipe 20 and the distance between the outer hemisphere 60 and the inner hemisphere 70 A space is formed.

The outer side of the outer hemisphere 60 is formed with a ring 61 for connecting a plurality of sub-balls to each other by using a rope.

The body 100 and the cover 200 of the present invention are made of polyethylene (PE) or polypropylene (PP), and are manufactured by injection molding and metal molds, and are adapted for mass production.

The inner pipe 20 is formed on the inner side of the outer pipe 10 as shown in FIGS. 3 and 4. The inner pipe 20 has a plurality of partitions 30 ) Are formed radially.

A plurality of first space portions 40 are radially formed by the partition 30 between the outer pipe 10 and the inner pipe 20 and a hollow space is formed inside the inner pipe 20 The second space portion 50 is formed.

The body 100 may be formed in the longitudinal direction by extrusion and cut by a required length.

The cover 200 has a double structure in which a plurality of partition walls 80 are formed between the outer hemisphere 60 and the inner hemisphere 70 to form a gap therebetween.

A pair of semi-spherical covers (200) having a double pipe structure according to the present invention are closely contacted to both sides of the body (100) and heated and fused by a heater to closely contact moisture and air .

Accordingly, the temperature difference between the outside and the inside is minimized by the double structure of the outer pipe 10, the inner pipe 20, and the first space portion 40 and the second space portion 50, As a result, moisture is not generated on the inner side of the bucket, and buoyancy can be prevented from being weakened.

In addition, since the plurality of partition walls 30 firmly support the outer pipe 10 and the inner pipe 20 together with the double pipe structure, the durability is improved and the service life is prolonged, so that the maintenance is easy and more economical.

5, the outer pipe 10a and the inner pipe 20a may be separated from each other, and the body 100a may be formed by combining the inner pipe 20a and the inner pipe 20a.

A plurality of coupling portions 11 are radially formed on the inner peripheral surface of the outer pipe 10a and a plurality of wing portions 31 corresponding to the coupling portion 11 are formed on the outer peripheral surface of the inner pipe 20a, The wing portion 31 can be coupled to the coupling portion 11 by sliding.

Therefore, the inner pipe 20a is coupled to the inner side of the outer pipe 10a so that the inner pipe 20a can be easily detached, thereby easily replacing the outer pipe 10a damaged by the external force.
