Description

Technical Field

[0001] This utility model belongs to the field of buoys, and in particular relates to a split-type environmentally friendly buoy. Background Technology

[0002] A buoy is a navigational aid that floats on the water's surface. Anchored in a designated location, it marks the extent of a waterway, indicates shoals, navigational obstructions, or serves a specific purpose. Buoys are the most numerous and widely used type of navigational aid, and they can also be used for water quality monitoring and surface marking. Compared to traditional buoys, buoys made primarily of ultra-high molecular weight polyethylene (UHMWPE) offer advantages in terms of environmental friendliness and corrosion resistance.

[0003] A modular buoy is a type of buoy composed of multiple independent parts. It is characterized by the use of multiple relatively independent chambers connected together, as shown in CN200720067613.2. The advantages of this type of buoy include: a reliable one-piece molding process, ensuring consistent product quality, improving production efficiency, and reducing production costs; and the independent sealed chambers provide better buoyancy integrity and stability, allowing the entire buoy to remain afloat even if some parts are damaged. However, large buoys require lifting rings for deployment and retrieval. These rings are often made of metal, which differs significantly from the material of the buoy body. Furthermore, the modular design necessitates maintaining the airtight seal of each chamber, requiring a well-designed buoy body to facilitate the bolting and securing of the lifting rings. Utility Model Content

[0013] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0014] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0015] Examples, such as Figures 1-7As shown, this utility model provides a split-type environmentally friendly buoy, including an upper tube 1 and a lower tube 2. The upper tube 1 is provided with a ladder 3, a lamp holder 4 for installing lamps, and a protective frame 5 for protecting the lamps. The lower tube 2 is provided with a counterweight assembly 6 near its bottom. Multiple floats 7 are provided between the upper tube 1 and the lower tube 2. Adjacent floats 7 are connected by through bolts 8. There are 3 floats 7, and the central angle of the floats 7 is 120 degrees. The top and bottom of the 3 floats 7 are respectively provided with an upper end cap 9 and a lower end cap 10 for connecting with the upper tube 1 and the lower tube 2. The top and bottom of the floats 7 are provided with rectangular grooves 71 that are recessed inward. At least 4 internally threaded tubes 72 are provided in the rectangular grooves 71. The upper end cap 9 and the lower end cap 10 are provided with fixing bolts 11 for cooperating with the internally threaded tubes 72. The fixing bolts 11 are provided on a fixing plate 12, and the fixing plate 12 is provided with a lifting ring 13.

[0016] Specifically, the upper tube 1, lower tube 2, upper end cap 9, lower end cap 10, and three floats 7 are all made of ultra-high molecular weight polyethylene, which has the advantages of being lightweight, environmentally friendly, and corrosion-resistant. This invention uses three 120-degree floats 7, giving the buoy the advantages of a split-type buoy. Even if some parts are damaged, the whole buoy can still float. Compared to two 180-degree floats 7, the force distribution after localized damage is better. Compared to four 90-degree floats 7, this buoy also has the advantage of lower cost. Furthermore, the upper end cap 9 and lower end cap 10 are used as a complete force-bearing surface on the upper and lower surfaces of the three floats 7. This improves the assembly quality of the three floats 7 and establishes multiple sealing surfaces with the floats 7, upper tube 1, and lower tube 2, thus improving the sealing reliability of the upper tube 1 and lower tube 2 in the middle part of the floats 7.

[0017] Furthermore, the float 7 is integrally molded, including the mounting surface of the through bolt 8, the rectangular groove 71, and the internally threaded tube 72, all of which are integrally molded to ensure the sealing integrity of the entire float 7. The float 7 is specially provided with a molded rectangular groove 71, and the internally threaded tube 72 is provided for connecting the fixing bolt 11. The fixing bolt 11 connects the fixing plate 12 and the lifting ring 13 from the upper surface of the upper end cover 9 and the lower surface of the lower end cover 10 all the way to the internally threaded tube 72. The thread engagement position has sufficient depth fit, which can not only install and fix the fixing plate 12 and the lifting ring 13, but also ensure that the lifting ring 13 has a long actual service life.

[0018] To improve the fit between the upper end cap 9, the floats 7, and the upper tube 1, the upper end cap 9 provided by this utility model includes an upper cover body 91. An upper collar 92 is located at the center of the upper cover body 91. A first bolt 93 is installed on the upper collar 92 and the upper tube 1. An upper positioning ring 94 is located on the edge of the upper cover body 91. The generatrix of the outer ring surface of the upper positioning ring 94 is an arc. An upper positioning groove 73 is provided on the float 7 to mate with the upper positioning ring 94. One side of the upper positioning groove 73 mates with the outer ring surface of the upper positioning ring 94. The upper collar 92 detachably fixes the entire upper end cap 9 to the upper tube 1 via the first bolt 93. The upper cover body 91 provides a relatively complete force-bearing surface and support surface. The upper positioning ring 94 is used to position the three floats 7, which helps improve the concentricity of the three floats 7 after assembly and reduces assembly gaps that may exist due to assembly and processing errors, thus improving the sealing performance of the buoy.

[0019] Furthermore, this invention provides a first sealing element 14 with a V-shaped cross-section between the outer surface of the upper positioning groove 73 and the upper positioning ring 94. The first sealing element 14 has two pages, which are pressed between the upper positioning ring 94 and the upper positioning groove 73 under assembly pressure. Its basic opening and closing characteristics can be automatically adjusted under thermal expansion and contraction conditions, which helps to improve the integrity of the assembly sealing surface of the upper positioning groove 73 and the upper positioning ring 94.

[0020] To improve the fit between the lower end cap 10 and the lower tube body 2, the lower end cap 10 provided by this utility model includes a lower cover body 101. A lower sleeve 102 is provided at the center of the lower cover body 101. A second bolt 103 is provided on the lower sleeve 102 and the lower tube body 2. A lower positioning ring 104 is provided on the edge of the lower cover body 101. A lower positioning groove 74 that mates with the lower positioning ring 104 is provided at the bottom of the float 7. An inner concave annular groove 75 is provided on the inner side of the lower positioning groove 74. A second sealing element 15 with an O-type design for sealing is provided in the inner concave annular groove 75. The lower sleeve 102 is detachably fixed to the outside of the lower tube 2 by the second bolt 103; the lower cover 101 provides a relatively complete force-bearing surface and support surface; the lower positioning ring 104 is used to position the three floats 7, and in conjunction with the positioning function of the upper positioning ring 94 on the floats 7, it can further improve the concentricity of the three floats 7 after assembly, and help to reduce assembly gaps that may exist due to assembly errors and processing errors, and further improve the sealing performance of this buoy.

[0021] To improve the buoy's performance in the sea, this invention features a design with plugged surfaces at both ends. The upper end is sealed via a lamp holder 4 connected to it by screws, while the lower end is sealed using a counterweight assembly 6. It should be noted that screws are used to connect and fix the protective frame 5, ladder 3, and counterweight assembly 6 to the corresponding foundations at the locations requiring fixation.

[0022] To improve the practicality of the counterweight assembly 6, the counterweight assembly 6 provided by this utility model adopts an external and detachable design. It includes an upper limit plate 61 located on the outside of the lower tube body 2 and a lower limit plate 62 nested at the bottom of the lower tube body 2. The end face of the lower limit plate 62 is a blocking surface. The upper limit plate 61 has a T-shaped hollow structure, and the lower limit plate is also a T-shaped design, but its bottom is a blocking surface and its vertical part is embedded inside the lower tube body 2. A counterweight block 63 is provided between the upper limit plate 61 and the lower limit plate 62. The upper limit plate 61 and the lower limit plate 62 are connected and fixed to the lower tube body 2 by screws / bolts. The relative distance between them is used to install a corresponding number and total thickness of counterweight blocks 63. The counterweight blocks 63 ensure the stability of the buoy in the sea area and prevent the buoy from nose-diving.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
