Description

Technical Field

[0001] This utility model relates to a rubber self-floating pipe for transporting mixtures of mud, sand and water in dredging projects, and more particularly to a rubber self-floating pipe connection structure. Background Technology

[0002] The dredging industry is developing rapidly. As one of the main rubber pipes used for transporting sediment on water, the self-floating rubber pipe is affected by the construction environment in actual use. Factors such as wave size, vessel traffic on waterways, and transport distance directly or indirectly affect the structure and markings of the self-floating pipe. On the one hand, traditional self-floating pipes may have insufficient sealing in flange connections, making them prone to leakage under external forces, affecting transport capacity. On the other hand, existing markings on self-floating pipes are easily worn or detached due to long-term exposure to the aquatic environment, causing inconvenience for on-site management. Furthermore, metal pipe joints and flanges are easily corroded and their performance reduced when exposed to seawater, ultraviolet radiation, and other environmental factors over a long period. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a rubber self-floating pipe connection structure with stable structure and clear markings.

[0004] To solve the above-mentioned technical problems, the rubber self-floating pipe connection structure of this utility model includes a hollow cylinder, conical frustums at both ends of the cylinder, and a pipe joint outside the conical frustums. The side with the larger cross-section of the conical frustum is connected to the cylinder, and the side with the smaller cross-section of the conical frustum is connected to the pipe joint. The pipe joint consists of a metal flange, a cylinder for connecting the metal flange and the conical frustum, ear plates evenly distributed along the circumference of the cylinder, and the metal flange, ear plates, and rubber on the surface of the cylinder forming an integral whole.

[0005] The metal parts of the pipe fitting surface are coated with black or red protective paint.

[0006] Three sets of several rubber rings spaced at a certain distance are arranged on the left, middle and right positions of the surface of the cylinder, and the rubber rings are arranged perpendicular to the length direction of the cylinder.

[0007] Four sets of markings are arranged between the three sets of strips. The four sets of markings are divided into two sets on the left and two sets on the right, which are 180° apart and staggered by 90° on the left and right sides.

[0008] The markings are arranged in a circumferential order.

[0009] Rubber-colored lettering is arranged circumferentially at 90° intervals on the sloping positions of the conical frustums at both ends of the cylinder.

[0010] The dial of the metal flange of the pipe fitting has welding marks, which are stainless steel welding marks with flanges.

[0011] Advantages of this utility model:

[0012] (1) The inclined surface of the cone-shaped truncated cone plays a depressurization role in the floating pipe connected by multiple rubber self-floating pipes, which is used to reduce the wind and wave pressure borne by the self-floating pipe cylinder.

[0013] (2) The two sets of markings are staggered by 90°, that is, one end is front and back, and the other end is up and down, so that the markings can be seen on every surface of the self-floating tube body, making it convenient to check the markings; the markings include trademark, number, working pressure, product code, salesperson code, production date and work group, which can trace the production process and the person in charge of the product, and can avoid unclear responsibilities or mutual shirking of responsibility.

[0014] (3) The bottom of the rubber pipe experiences the most wear during transportation, and the wear gradually decreases from the bottom to the sides and then to the top, meaning the top experiences the least wear. To maximize the service life of the self-floating pipe, it should be flipped when the pipe is significantly worn but not yet damaged, which can nearly double its lifespan. The pipe fitting of this utility model has a welding mark on the surface to indicate the installation and use location, as well as the flipped position of the pipe. Attached Figure Description

[0021] The rubber self-floating pipe connection structure of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1-4As shown, the rubber self-floating pipe connection structure includes a hollow cylinder 1, conical frustums 2 at both ends of the cylinder 1, and a pipe joint 3 outside the conical frustums 2. The smaller cross-sectional side of the conical frustum 2 is connected to the pipe joint 3 for pressure relief, and the larger cross-sectional side of the conical frustum 2 is connected to the cylinder 1. The pipe joint 3 includes a metal flange 4, a cylinder 6 for connecting the metal flange 4 and the conical frustum 2, and ear plates 5 evenly distributed along the circumference of the cylinder 6. The metal flange 4, cylinder 6, and ear plates 5 are integrated by being covered with rubber to reduce the pressure on the cylinder 1. The rubber on the surface of the metal flange 4 and cylinder 6 is black, and the metal part on the surface of the pipe joint 3 is coated with black or red protective paint to prevent seawater corrosion.

[0023] Three sets of orange rubber rings 10, spaced at regular intervals, are arranged on the left, center, and right sides of the surface of cylinder 1. These rubber rings 10 are perpendicular to the length of cylinder 1. When used on site, a multi-section self-floating pipe floats on the water, and the exposed orange rubber is highly visible, similar to a traffic sign, allowing passing vessels to clearly see it and maneuver accordingly to avoid the self-floating pipe. Four sets of markings 7 are placed between the three sets of rings 6. These markings are divided into two sets 180° apart on the left and two sets 180° apart on the right, staggered by 90° on each side (one end forward and backward, the other end up and down), ensuring that the markings are visible on every surface of the self-floating pipe. The label is easy to view; the specific content includes: trademark, number, working pressure, product code or specification, salesperson code, production date and work group, etc. One or more of the content can be selected as needed and placed in the center of the labeling area. All labels are arranged in a circumferential order, interconnected yet separate. All labels, except for the optional trademark, are made of orange rubber and can be vulcanized into the self-floating pipe body. The product code and salesperson code on this label are specially set as needed. The product code can identify the product specifications, product type, pressure and corresponding traceable production process. The salesperson code indicates who is responsible for leading all after-sales service for this product. With a large variety of products, this can avoid confusion of responsibility.

[0024] The sloping positions of the conical frustums 2 at both ends of the cylinder 1 are circumferentially arranged with colored rubber lettering 8 at 90° intervals; the metal flange 4 of the pipe joint 3 has welded lettering 9, which is a flanged stainless steel welded letter, and the content of the welded lettering includes position numbers, quantity, company code, and other identification, such as... Figure 5 , 6 As shown, the numbers 1, 2, 3, and 4 are placed on the cylinder body next to the ear plate on the pipe joint 3. The stainless steel letters are welded and the direction of the letters follows the outer circle of the flange, with one letter every 90°. They correspond one-to-one with the numbers 1, 2, 3, and 4 of the rubber colored letters 8 on the upper surface of the conical truncated cone 2, and are aligned on a line.
