Description

Technical Field

[0001] The utility model relates to the technical field of pipes, in particular to a guide device used on a water-permeable pipe. Background Art

[0002] At present, mesh-shaped rigid water-permeable pipes are widely used because they are superior to traditional perforated mesh-shaped rigid water-permeable pipes in water permeability. The structure of mesh-shaped rigid water-permeable pipes can refer to Chinese patent No. CN201220159447.X.

[0003] During the process of burying the mesh-shaped rigid water-permeable pipe, a guide head is usually installed at the end of the mesh-shaped rigid water-permeable pipe so that the mesh-shaped rigid water-permeable pipe can play a guiding role when moving in the underground trench. However, since the mesh-shaped rigid water-permeable pipe has a high hardness and is not easy to deform, in order to facilitate insertion into the accommodating cavity of the guide head, the inner diameter of the accommodating cavity of the guide head is usually larger than the outer diameter of the mesh-shaped rigid water-permeable pipe. However, there is a lack of effective fixing and positioning mechanism between the guide head and the mesh-shaped rigid water-permeable pipe, which causes the guide head to be easily displaced eccentrically relative to the end of the mesh-shaped rigid water-permeable pipe during the movement of the water-permeable pipe, affecting the guiding function of the guide head; and the guide head is also easy to slip off the mesh-shaped rigid water-permeable pipe, increasing the difficulty and risk of construction.

[0029] Reference Figure 1-6A guide device used on a water-permeable pipe comprises a guide portion 1 for guiding and an insertion portion 2 for inserting and clamping in the lumen of the water-permeable pipe 100, wherein the guide portion 1 and the insertion portion 2 are connected along the axial direction, and the diameter of the guide portion 1 gradually increases from the end away from the insertion portion 2 to the end connected to the insertion portion 2, so that the guide portion 1 has a bullet-shaped appearance, so that the guide portion 1 can use the end with a small diameter to act on the first end for guiding; the outer surface of the insertion portion 2 is provided with a limiting convex ring 3 along the circumferential direction for abutting against the end of the water-permeable pipe 100 to realize the insertion limit of the insertion portion 2. When installing the guide device, the insertion part 2 is inserted into the tube cavity of one end of the water-permeable pipe 100 until the limiting convex ring 3 abuts against the end face of one end of the water-permeable pipe 100. At this time, the insertion part 2 cannot continue to move along the direction of inserting into the tube cavity of the water-permeable pipe 100. The insertion part 2 is clamped and fixed in the tube cavity of the water-permeable pipe 100, thereby completing the installation of the guide device; when the guide device is in use, the guide part 1 can guide the water-permeable pipe 100 during the movement in the underground trench, thereby improving the laying efficiency of the water-permeable pipe 100.

[0030] The utility model first inserts the insertion part 2 into the lumen of the water-permeable pipe 100, and then uses the limiting convex ring 3 to abut against the end of the water-permeable pipe 100 to limit the matching position between the insertion part 2 and the water-permeable pipe 100, so that the insertion part 2 can be tightly clamped in the lumen of the water-permeable pipe 100, and the effective fixation and positioning between the guide device and the water-permeable pipe 100 is achieved, avoiding the problem of eccentric displacement or slippage of the guide head during the movement of the water-permeable pipe 100, so that the guide part 1 can provide a stable guiding effect when the water-permeable pipe 100 moves in the underground trench, so that the water-permeable pipe 100 can be accurately laid according to the predetermined path, greatly improving the laying efficiency. Moreover, the guide device provided by the utility model adopts the insertion part 2 and the limiting convex ring 3 to cooperate with the water-permeable pipe 100 for installation, which is simple to install and easy to operate, does not require additional fixing tools or materials, simplifies the construction process, and reduces the construction cost.

[0031] As a preferred embodiment, the insertion part 2 includes an insertion shaft body 21 connected to the guide part 1 and a plurality of clamping structures arranged on the outer peripheral surface of the insertion shaft body 21, and the plurality of clamping structures are distributed along the circumference of the insertion shaft body 21. The plurality of clamping structures include a plurality of clamping protrusions 22 for clamping on the wall of the lumen of the water-permeable pipe 100, and the plurality of clamping protrusions 22 are arranged axially along the insertion shaft body 21. When the insertion part 2 is inserted into the lumen of the water-permeable pipe 100, the clamping protrusions 22 will clamp on the wall of the lumen of the water-permeable pipe 100, thereby completing the purpose of fitting the insertion part 2 in the water-permeable pipe 100.

[0033] As a preferred embodiment, a plurality of first through hole structures are circumferentially arranged on the outer circumferential surface of the guide portion 1, and the first through hole structure includes a first connecting hole 11 arranged on the outer circumferential surface of the guide portion 1, and the first connecting hole 11 is connected to the guide cavity 10. During the movement of the guide device in the underground trench, water in the underground trench can flow from the first connecting hole 11 into the permeable pipe 100, thereby reducing the probability that the water in the underground trench affects the movement of the guide device in the underground trench.

[0034] As a preferred embodiment, the outer circumferential surface of the guide part 1 is provided with a plurality of second through hole structures along the circumferential direction, and the second through hole structures include a concave groove 12 recessed on the outer circumferential surface of the guide part 1 and a plurality of second connecting holes 13 provided on the groove surface of the concave groove 12, and one end of the plurality of second connecting holes 13 is connected with the guide cavity 10, and during the movement of the guide device in the underground trench, the water in the underground trench can flow into the water-permeable pipe 100 from the second connecting holes 13, thereby reducing the probability that the water in the underground trench affects the movement of the guide device in the underground trench. In addition, since the second connecting holes 13 are located in the concave groove 12, the other end of the second connecting holes 13 is at a distance from the outer circumferential surface of the guide part 1, so that even if the soil adheres to the outer circumferential surface of the guide part 1 during the movement of the guide part 1 in the underground trench, the inlet of the second connecting holes 13 can be at a certain distance from the outer circumferential surface of the guide part 1 under the action of the concave groove 12, so that a part of the water first flows into the concave groove 12 and then enters the guide cavity 10 through the second connecting holes 13.

[0035] In this embodiment, in order to make the first through hole structure and the second through hole structure evenly distributed on the outer peripheral surface of the guide part 1 so that the first connecting hole 11 and the second connecting hole 13 can enter water in any direction of the guide part 1, at least one first through hole structure is arranged between the circumferentially adjacent second through hole structures.

[0036] As a preferred embodiment, the outer circumferential surface of the insertion part 2 is provided with a guide circumferential surface 23 along the circumferential direction, one end of the guide circumferential surface 23 is connected to the outer circumferential surface of the insertion part 2, and the other end is connected to the end surface of the insertion part 2 away from the guide part 1, and the diameter of the guide circumferential surface 23 gradually decreases from one end to the other end, so that the insertion part 2 uses the guide circumferential surface 23 as a guide, which is convenient for the insertion part 2 to be inserted into the water-permeable pipe 100.

[0037] As a preferred embodiment, one end of the limiting convex ring 3 is connected to the guide part 1, thereby improving the connection stability between the guide part 1 and the insertion part 2. In addition, the insertion part 2, the guide part 1 and the limiting convex ring 3 are integrally formed and connected by injection molding, and the structure has high stability.
