Abstract

The invention discloses a silt-accumulation-preventing drain pipe which comprises a pipe body (1) which is circular in the radial direction and two ball bearings, wherein an outer ring (2) of each bearing is respectively connected with the inner wall surfaces of two ends of the pipe body (1), and inner rings (3) of the two bearings are connected in an inclined mode through four triangular prisms (4). When water flow passes through the pipe body (1) in parallel, the water flow impacts each side surface of the triangular prism (4) to push each triangular prism (4) and the inner ring (3) of the bearing to rotate in the pipe body (1) to form a stirrer, so that the water flow containing rain dirt is stirred to pass through the pipe body (1) in a rotating state, and therefore the deposition of dirt on the lower inner wall of the pipe body (1) is avoided or reduced. If necessary, the pipe body (1) can be dredged and the stirring function thereof can be maintained by manually rotating the triangular prism (4) at the open caisson facility adjacent to the pipe body (1).

Description

Prevent ponding drain pipe

Technical Field

The invention belongs to a drain pipe, and particularly relates to a sludge-accumulation-preventing drain pipe.

Background

The existing drain pipe horizontally buried underground is long in service time, the lower inner wall of the pipe body silts up due to sediment of dirt, so that the drift diameter of the pipe body is smaller and smaller, and the drain pipe is difficult to replace or dredge due to the fact that the drain pipe is usually buried underground. Therefore, it is very important to provide a silting-proof drain pipe.

Disclosure of Invention

The invention aims to provide an anti-silting drain pipe.

The invention relates to an anti-deposition drain pipe, which comprises a radial circular pipe body and two ball bearings, wherein the outer ring of each bearing is respectively connected with the inner wall surfaces at two ends of the pipe body, and the inner rings of the two bearings are obliquely connected by a plurality of triangular prisms.

The invention has the following beneficial effects:

because the inner rings of the two bearings are obliquely connected by the plurality of triangular prisms, when water flows pass through the pipe body in a manner of being parallel to the pipe body, the water flow impacts each side surface of the triangular prisms so as to push each triangular prism and the inner ring of the bearing to rotate in the pipe body to form a stirrer, so that the water flow containing rain sewage is stirred to pass through the pipe body in a rotating state, and therefore, the sludge deposition on the lower inner wall of the pipe body is avoided or reduced; if necessary, the triangular prism can be manually rotated at the open caisson facility adjacent to the pipe body, so that the pipe body is dredged and the stirring function of the pipe body is maintained.

Drawings

FIG. 1 is a schematic view of the radial end face structure of a silt-proof drain pipe of the present invention.

Fig. 2 is a schematic top view of the anti-silting drain pipe of the present invention.

Detailed Description

The invention is further described below with reference to the accompanying drawings.

As shown in figure 1 or figure 2, the anti-deposition drain pipe comprises a pipe body 1 which is circular in the radial direction and two ball bearings, wherein an outer ring 2 of each bearing is respectively connected with the inner wall surfaces of two ends of the pipe body 1, and inner rings 3 of the two bearings are obliquely connected through four triangular prisms 4. The pipe body 1 is made of rubber or concrete, and the distance between the triangular prisms 4 and the inner wall surface of the pipe body 1 is 2-5 mm.

If necessary, after flood, a large amount of sand may be accumulated in the pipe body 1, so that the stirring function of the pipe body 1 is also damaged, but if the triangular prisms 4 are manually rotated at the open caisson facility adjacent to the pipe body 1 in the presence of water flow, the sand can be pushed to the open caisson facility, and the stirring function of the pipe body 1 is restored to normal.

Claims

1. The anti-deposition drain pipe comprises a pipe body (1) which is circular in the radial direction and two ball bearings, and is characterized in that an outer ring (2) of each bearing is respectively connected with the inner wall surfaces at two ends of the pipe body (1), and inner rings (3) of the two bearings are connected in an inclined mode through four triangular prisms (4);

after flood, when a large amount of sand and soil is accumulated in the pipe body (1) so that the stirring function of the pipe body (1) is damaged, the inner ring (3) of the bearing can be manually rotated at the open caisson facility adjacent to the pipe body (1), and the sand and soil are pushed to the open caisson facility by the continuous inclined surface between the two inner rings (3) of each triangular prism (4) which inclines to the opening of the pipe body (1), so that the stirring function of the pipe body (1) is restored to be normal.
