It is constructed to have a stable structure that is not damaged or deformed while enduring a high load.

Hereinafter, a lower cover sealing type float according to an embodiment of the present invention will be described in more detail.

The float body 100a has an integrated upper plate 110a and an outer wall 110b, the lower surface is molded in an open shape, and is formed in a container shape with an open lower surface as a whole. The open lower surface of the float body 100a is covered by a lower cover 100b having no separate inner space. According to the unique configuration of the present invention in which the internal space necessary for buoyancy formation is allocated only to the float body 100a and an open surface is formed on the lower surface rather than the upper surface, the float main body 100a unless the float main body 100a is overturned on the water surface. ) has the great advantage of being able to stand on its own without losing buoyancy even without the lower cover 100b as the air pockets are naturally formed in the inner space of the.

The float body 100a is further formed with an internal partition wall 120 that divides the internal space. The inner partition wall 120 is formed in a diagonal direction by connecting the corner portions and the corner portions facing each other inside the float body 100a, and is formed in plurality so as to intersect at the center portion. As such, the lower cover sealed float according to the embodiment of the present invention is provided as a multi-room float in which the inner space of the float body 100a is divided by a plurality of inner partition walls 120 . A point to be noted with respect to the inner partition wall 120 is that, as described above, the inner partition walls 120 are formed in a diagonal direction by connecting the corner portions and the corner portions facing each other. According to this configuration, the divided spaces formed by the inner partition wall 120 in the inner space of the float body 100a form a continuous triangular structure composed of one outer wall 110b and two inner partition walls 120, and are relatively compared to the rectangular structure. It has a structure that is strong against breakage or deformation while enduring a high load.

More importantly, the inner partition wall 120 forms a supporting structure supporting the corner portions 111 and the corner portions 111 that are opposed to each other in the inner space of the float body 100a in the form of connecting them. Accordingly, as shown in FIG. 6 , a fastening ring 140 fastened by a fastening pin 145 spanning through a fastening hole 141 is installed on the outside of the corner 111 of the float body 100a, so that the adjacent floats In the case of fastening with the fastening pin 145 as the center, it is possible to effectively suppress the easy breakage in the form of the corner 111 falling off due to the tensile force applied to the corner 111 through the fastening pin 145 . there will be

A plurality of fusion protrusions penetrated through the lower end of the outer wall 110b and the lower end of the inner partition 120 of the float body 100a corresponding to the coupling hole 161 formed in the lower cover 100b and then fused to the lower cover 100b. 130 is further formed. In the case of the fusion protrusion 130, before fusion, it penetrates through the coupling hole 161 of the lower cover 100b as shown in FIG. 7b and protrudes downwardly. When the fusion progresses and is compressed, the lower cover (as shown in FIG. 7c) ( While completely filling the coupling hole 161 of 100b), it is stably bonded to the lower cover 100b. Here, the fusion protrusion 130 is formed as a line-shaped protrusion corresponding to the coupling hole 161 of the lower cover 100b formed in the shape of a long hole, and after being fused, the coupling hole 161 can be filled.

The lower cover 100b is joined to the float body 100a while covering the open lower surface of the float body 100a.

In addition, the fitting groove 160 is further formed in a diagonal direction so as to intersect at the central portion while connecting the opposite corner portions in the lower cover 100b to correspond to and closely fit to the lower end of the inner partition wall 120 . In the case of the lower cover 100b, except for the portion where the fitting groove 160 is formed, it is only a thin plate having a thickness of 50 mm or less, and even considering the portion where the fitting groove 160 is formed, the vertical height is only 100 mm or less. do. It can be noted that compared to the vertical height of the lower cover 100b, the vertical height of the float body 100a is formed to be 300 mm or more, so that the magnification is 30 times or more. For example, if the dimensions of each part are measured based on a recently produced sample, the float body 100a is 384 mm in top and bottom height except for the fusion protrusion 130, and the front and rear width and left and right width 515 mm except for the fastening ring 140. , The lower cover (100b) is made of a material having a softer and more elastic than the upper and lower height float body (100a). The float body 100a was made of a high-density polyethylene (HDPE) material, and the lower cover 100b had a vertical height of 62 mm, a front and rear width, and a left and right width of 519 mm including the portion where the fitting groove 160 was formed.

Here, it may be made of a low-density polyethylene (LDPE) material that is softer than the float body 100a. According to this configuration, the lower end of the outer wall 110b and the lower end of the inner partition 120 of the float body 100a are closely fitted into the fitting groove 160 of the lower cover 100b without a separate bonding process or fusion process, and the lower cover (100b) is coupled in close contact with the float body (100a). The inner space of the float body 100a is sealed by the lower cover 100b.

A plurality of coupling holes 161 are formed in the lower cover 100b to be spaced apart from each other along the fitting groove 160, and the coupling holes 161 are formed in the shape of a long hole. Accordingly, a plurality of fusion protrusions 130 formed as line-shaped protrusions at the lower end of the outer wall 110b of the float body 100a and the lower end of the inner partition 120 corresponding to the coupling hole 161 are the coupling holes 161. It can be fused after being inserted in a state of being penetrated through the As such, when the fusion protrusion 130 of the float body 100a penetrates the coupling hole 161 formed in the fitting groove 160 of the lower cover 100b and is fused, the lower cover 100b is formed with respect to the float body 100a. separation can be prevented. In particular, it protects the lower cover 100b from being separated from the float body 100a when water pressure is constantly applied in various directions due to the irregular movement of seawater.

A plurality of reinforcing protrusions 170 forming a protrusion line by forming a row with a plurality of fusion protrusions 130 on the protruding portion 160a protruding downward due to the formation of the fitting groove 160 on the lower surface of the lower cover 100b. ) is formed. This reinforcing protrusion 170 is integrally formed with the lower cover 100b and basically serves to reinforce the strength of the lower cover together with the fusion protrusion 130 . It should be noted here that the reinforcing protrusion 170 is formed to protrude a little further downward than the fusion protrusion 130 . As a result, external contact or external force is mainly applied to the reinforcing protrusion 170 integrally formed on the lower cover 100b. can The reinforcing protrusion 170 also serves as a support leg for supporting the whole while in contact with the ground or a float located on the lower side when the float is loaded.
