DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0034] See also Figure 1-9The self-floating mud-draining hose with high stability is shown, which is provided with a hose body 1. A male flange 2 and a female flange 2 are provided at each end of the hose body 1 for connecting two mud-draining hoses. A positioning boss 8 is provided on the male flange 2, and a positioning groove 10 that cooperates with the positioning boss 8 is provided on the female flange 3. When the two mud-draining hoses are connected, the positioning boss 8 and the positioning groove 10 cooperate with each other, and the positioning boss 8 fits into the positioning groove 10 in a clearance fit manner, which facilitates the positioning work when the two mud-draining hoses are connected, and also makes it easier for staff to lock the male flange 2 and the female flange 3 on the two mud-draining hoses. In order to improve the sealing performance of the connection between the two mud-draining hoses, a first sealing ring groove 9 is provided on the male flange 2, and a second sealing ring groove 11 is provided on the female flange 3. After the two mud-draining hoses are connected, the first sealing ring groove 9 and the second sealing ring groove 11 form a complete arc-shaped cavity for installing a sealing rubber ring.

[0035] The mud drainage hose is also equipped with a floating layer 4, a reinforcement layer 5, and an outer coating 6. The floating layer 4 is made of closed-cell foam and provides the necessary buoyancy. The reinforcement layer 5 is made of hard rubber and protects the floating layer 4 and the hose body 1 from external impacts. To further enhance the hose's overall corrosion and impact resistance, an outer coating 6 made of polyester resin is applied to the outer surface of the reinforcement layer 5, along with an anti-corrosion coating applied to the inner wall of the hose body 1. The adhesion between the reinforcement layer 5 and the outer coating 6 is no less than 4 k / m.

[0036] To facilitate stacking of the mud-draining hoses, an arc-shaped groove 7 is provided on the outer covering 6, and the inner diameter of the arc-shaped groove 7 matches the outer diameter of the outer covering 6. When two mud-draining hoses are stacked, the inner diameter of the arc-shaped groove 7 can completely fit on the outer diameter of the outer covering 6. At the same time, because the connection between the male and female flanges 2 and 3 and the hose body 1 is not an integrally formed structure, their integrity is relatively weak. If both are subjected to force during stacking, damage to the connection is likely to occur. Furthermore, the height of the outer covering 6 is designed to be higher than that of the male and female flanges 2 and 3 to prevent damage to the connection due to external forces when the two mud-draining hoses are stacked.

[0037] To address the high center of gravity problem of conventional float-connected mud-discharge hoses, the floating layer 4 is divided into two parts: an upper float 4a and a lower float 4b, symmetrically positioned relative to the upper float 4a. In actual operation, the lower float 4b is submerged in the water, with the lower float 4b at the bottom and the upper float 4a at the top. The upper and lower floats 4a and 4b are sleeved onto the outer wall of the hose body 1 and are connected to the hose body via adhesive, with an adhesive strength of no less than 3 k / m. The lower float 4b is provided with a first through-hole 4e and a second through-hole 4f, located midway between the two first through-holes 4e. A first weighting rod 4g is positioned in each of the first through-holes 4e, while a second weighting rod 4h is positioned in the second through-hole 4f. The weight of the second weighting rod 4h is greater than the combined weight of the two first weighting rods 4g. Both the first weighting rod 4g and the second weighting rod 4h are made of metal. By providing a first weight-increasing rod 4g and a second weight-increasing rod 4h on the lower float 4b, the weight of the lower float 4b is increased, thereby lowering the center of gravity of the entire mud discharge hose. To facilitate the docking and installation of the upper and lower floats 4a and 4b on the hose body 1, waist-shaped grooves 4c are provided on both sides of the upper float 4a, and connecting bosses 4d corresponding to the waist-shaped grooves 4c are also provided on both sides of the lower float 4b. When the upper and lower floats 4a and 4b are assembled and connected, the waist-shaped grooves 4c and the connecting bosses 4d are connected by an interference fit.
