Detailed Description

As shown in figure 1, the splicing type buried pipe comprises a plurality of fixed shaft sleeves 5 which are arranged on a pipeline laying area in a hollow mode, the bottoms of the fixed shaft sleeves 5 are fixedly positioned on the ground, movable cavities 6 with openings at the outer ends are arranged inside the fixed shaft sleeves 5, splicing pipes 100 extend into the movable cavities 6, a damping piston 2 is sleeved on the splicing pipe 100 at the innermost end, the damping piston 2 is in sealing contact with the inner wall of the movable cavity 6, one side, far away from the opening ends, of the fixed shaft sleeves 5 is provided with a connecting joint 3, the fixed shaft sleeves 5 on two sides are connected through the connecting joint 3, one end of the connecting joint 3 extends into the movable cavity 6, the splicing pipe on the inner side end is sleeved with a compression spring 4, the compression spring 4 pushes out the splicing pipe 100 with the damping piston 2 outwards, the splicing pipe 100 is formed by splicing more than one water conveying pipe 7, and two sides of each water conveying pipe 7 form a section of shearing section respectively.

In this embodiment, the shearing section includes the sealing joint 71 that sets up in the protruding setting of every raceway one side, the outside end of sealing joint 71 is the water delivery mouth, the opposite side of every raceway forms a spherical sealed assembly mouth (not shown), the sealing joint of the raceway 7 of adjacent end inserts in the sealed assembly mouth contact seal, more than one raceway 7 passes through sealing joint 71 butt joint, sealing performance is very good after the assembly, as with normal pipe-line transmission, can increase and decrease the quantity of raceway 7 according to the pipeline needs can, more nimble in the use.

In this embodiment, an annular breaking groove 74 is disposed at the tail end of the sealing joint 71, the outer diameter of the annular breaking groove 74 is smaller than that of the sealing joint 71, the wall thickness of the annular breaking groove 74 is 2mm, and the wall thickness of the whole water pipe is 5 mm. When one of the water pipes is cut, the two sides of the cut water pipe are directly broken and separated along the annular breaking grooves 74, and the fractures on the two sides are neat, so that the butt joint and recombination are convenient.

As shown in fig. 3 and 4, a tapered insertion portion 73 is formed at one side of the annular fracture groove 74 close to the water pipe, an O-ring seal 72 is wrapped at the tail end of the tapered insertion portion 73, when the seal joint 71 is inserted into the water pipe at one side, the O-ring seal 72 is in contact seal with the seal assembly port of the water pipe 7 at one side, after the cut water pipes are separated, the pair of water pipes at two sides of the water pipe which are not cut are in butt joint again, so that the tapered insertion portion at one side is inserted into the water pipe at the other side and is in butt joint through the O-ring seal, at this time, the pipes at two sides are not connected by the seal joint any more, butt joint sealing can be realized only by elastic pressing force of a spring, but sealing performance can be sufficiently ensured after the butt joint by the spring, and more precious time is won for later.

As shown in fig. 2, the damping piston 2 is a rubber ring, which is sleeved outside the splicing pipe 100 and fixed by glue, and has two functions, one is to seal the whole movable cavity, and the second is to utilize the friction force between the damping piston and the inner wall of the movable cavity after the sheared water pipe is separated, so that the speed of the spring can be reduced when the spring is ejected out of the water pipe, and the speed of the spring to recover the deformation should be reduced as much as possible, which has the advantage that the external equipment can repeatedly act during shearing because the shearing is continuous and extensive, so that the benefit of recovering the deformation slowly is that the secondary operation cutting cannot occur, therefore, after the first cutting, a larger hollow area is left, and the pipeline in the area is sheared and separated, so that the pipeline can not be sheared again even if the secondary cutting occurs, and thus the operator is left enough time to find the water source, the shearing is stopped.

In this embodiment, the outer opening end of the movable cavity 6 is provided with a limiting covering edge 51, the inner ring of the limiting covering edge 51 is bonded with a waterproof sealing ring, the splicing pipe penetrates through the waterproof sealing ring and is sealed through the waterproof sealing ring, and the limiting covering edge is used for supporting and sealing the outer part of the splicing pipe.

In the present embodiment, the bottom of the fixed shaft sleeve 5 is provided with the ground insertion rod 1, and the fixed shaft sleeve 5 is fixed on the ground through the ground insertion rod 1, as long as the fixed shaft sleeve 5 can be fixed on the ground, and the structure of the ground insertion rod, the structure of the support, and the like can be used. In this embodiment, the depth of the movable cavity inside the fixed shaft sleeve should be within the length of at least two water pipes, so that even if 2 or 3 water pipes are cut off, the movable cavity has the length of being re-butted.

Wherein, attach fitting 3 is "well" font, and its both sides respectively form a screw assembly portion, and it and the fixed axle sleeve screw assembly of both sides can increase the quantity of fixed axle sleeve according to the length of laying of water pipe, and the interval between the adjacent fixed axle sleeve is difficult for the overlength, otherwise the concatenation pipe is difficult to bear weight.

After the splicing pipes are separated, the compression spring 4 cannot be quickly deformed under the action of the damping piston 2, only can be slowly deformed, and when the splicing pipes on two sides are in butt joint again, the butt joint can be realized again for sealing.

The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the inventive work should be included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
