Specifically, the upper end and the lower end of the semi-annular body are provided with bolt socket holes for connecting the two semi-annular bodies, so that the connection between the two semi-annular bodies is stable, and the disassembly and assembly are convenient.

Preferably, the through hole is located at the center of the upper end surface or the lower end surface of the semi-circular ring body, so that the filler in the semi-circular ring body can be conveniently discharged.

Specifically, the opening and closing component is a hole plug.

Preferably, the excircle radiuses of the annular bodies at any positions along the axial direction are equal, so that the floating and supporting capacity of the floating and supporting device for the pipelines in unit length is increased, and the number of the floating and supporting devices for the pipelines in unit length above water is saved.

Preferably, chamfers are arranged between the outer circle side wall and the upper end face of the circular ring body and between the outer circle side wall and the lower end face of the circular ring body, so that drag force during dragging is reduced, and the phenomenon that the circular ring body is clamped by impurities in water or on a bank side is avoided.

After the structure more than adopting, compared with the prior art, the utility model has the following advantage: the function of filling the interior of the semicircular ring body is realized by designing the openable through hole on the upper end surface or the lower end surface of the semicircular ring body and increasing the cavity in the semicircular ring body, so that the floating capacity of the semicircular ring body can be changed when needed, the overwater pipeline can be properly sunk, and the channel is dredged; the connecting part of the semi-circular ring body is arranged on the upper end surface and the lower end surface of the semi-circular ring body, so that a cylinder with a smooth outer circle side wall is formed after the semi-circular ring body is connected, the impact of water flow is effectively reduced, and the abrasion of the connecting part caused by the intermittent torsion of the water pipeline is reduced.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Example 1

As shown in fig. 1 and fig. 2, the pipe floating device of the present invention: the inside of semi-torus is equipped with cavity 1, and the up end of semi-torus is equipped with through-hole 2, and cavity 1 passes through-hole 2 and external intercommunication. From the viewpoint of easy filling and good appearance, the through hole 2 should be located at the geometric center of the upper end surface. Of course, the through hole 2 may be provided on the lower end surface or any side wall of the semi-circular ring body as required. The through holes 2 are all equipped with an opening and closing component 3, the opening and closing component 3 is used for controlling the opening or closing of the through holes 2, and the opening and closing component 3 can be a hole plug, or a turning plate or a knob, so that the operation is convenient, and meanwhile, the cavity 1 can be separated from the outside when the through holes 2 are closed.

As shown in fig. 3, the ring width surfaces 5 of the two semicircular rings are opposite to each other and detachably connected through the upper end surfaces and the lower end surfaces of the semicircular rings to form a circular ring. The inner circular side wall of the circular ring body is used for arranging the water pipeline, and the outer circular side wall is a flat curved surface.

The detachable connection mentioned above means: the upper end surface or the lower end surface of each semi-circular ring body is internally concave to form a groove, a bolt socket hole is formed at the bottom of the groove, the opening direction of the bolt socket hole 4 is vertical to the ring width surface 5, and the two semi-circular ring bodies are connected through the bolt socket hole 5; or a groove is arranged at the junction of the upper end surface or the lower end surface of the semi-circular ring body and the ring width surface 5, a screw hole is arranged on the side wall of the groove vertical to the direction of the ring width surface 5, and the two semi-circular ring bodies are connected through a stud;
