TECHNICAL FIELD
[0001] The present application relates to the technical field of land management, in particular to a hidden subsurface pipe assembly for land management. BACKGROUND
[0002] In the field of land salinization management and farmland drainage engineering, underground subsurface pipe drainage system is an important soil improvement technology, and the reliability of the core component of the subsurface pipe connection structure directly affects the operation efficiency of the entire drainage system. The current commonly used subsurface pipe connection technology mainly uses a connecting piece to assist in connecting the subsurface pipe.
[0003] For example, a patent with the name "Subsurface pipe salt drainage pipe connecting piece" and the authorization announcement date of May 3, 2024 (CN220891268U) belongs to the technical field of subsurface pipe salt drainage, and particularly relates to a subsurface pipe salt drainage pipe connecting piece. The connecting piece main body is cylindrical, and a plurality of split hooks are arranged at the ends of the connecting piece main body along the central axis direction. The open end of the split hook is located at the end of the connecting piece main body, and a locking piece is arranged outside the split hook. A barrier is arranged in the inner wall of the connecting piece main body, and a plurality of through holes are symmetrically arranged at the two ends of the connecting piece main body on both sides of the barrier. Split hooks are arranged in the through holes at both ends, and the split hooks directly extend into the valley position. The locking piece fixes and connects the corrugated pipe and the subsurface pipe salt drainage pipe connecting piece from the outside, and the split hook clamps the corrugated pipe wave crest to prevent falling off. The connecting piece has firm connection and anti-falling property, and is beneficial to mechanical continuous laying.
[0004] The above-mentioned patent and other similar patents have the following disadvantages. The split hooks arranged at the two ends of the connecting piece are fixed by clamping into the corrugated pipe wave crest, but the split design of the hooks may cause gaps between the hooks. If the locking piece cannot uniformly press or is deformed by soil pressure for a long time, these gaps may become water leakage channels. In addition, only the physical clamping of the hooks and the corrugated pipe is relied on, and material aging or deformation may occur after long-term use, resulting in a decrease in sealing performance.

[0030] In the above embodiment, the butt joint portion is preferably a stepped pipe so that the abutting member 6 can abut on the first pipe 1 and the second pipe 2, but correspondingly, a protrusion or a groove or the like can be provided on the first pipe 1 and the second pipe 2 to provide a force point for the abutting member 6, but the stepped pipe itself is a connection structure of the end portions of many pipes, so this feature is used, and there is no need to design a force point additionally. As a further optional way, an arc-shaped metal sheet can be bonded on the part of the stepped pipe abutting on the abutting member 6 to increase the force area, reduce the deformation amplitude caused by abutting, and prolong the service life.
[0031] In optional embodiments, the abutting member 6 has a certain damping force with the rotation of the driving cylinder 4 (the rotation friction of the rotation shaft 7 is reasonably configured, and details are not described), that is, after the abutting member 6 is operated by an external force, it can be stopped at any position by relying on the damping force and is not free to swing, so as to reduce the difficulty of operation caused by the free swing of the abutting member 6 in the operation process.
[0032] The application provides a land treatment hidden pipe assembly. After the first pipe and the second pipe are sealed and connected, the two driving cylinders are relatively moved by rotating the manual cylinder, and then the abutting member is manually rotated to abut in the connecting cylinder. At this time, the driving cylinder slides in the connecting cylinder by rotating the manual cylinder, and the connecting cylinder slides to drive the abutting member to slide until the end of the abutting member abuts on the first pipe and the second pipe, so that the ends of the first pipe and the second pipe abut on the connecting cylinder.
[0033] In another embodiment of the application, as shown in the figure, Figure 4 In order to solve the problem, a plurality of protrusions 8 are arranged in an annular array on the outer wall of the connecting part of the first pipe 1 and the second pipe 2, and the protrusions 8 are arranged in one-to-one correspondence with the abutting member 6. Preferably, four protrusions 8 are arranged. The protrusion 8 is approximately triangular and has two connected inclined surfaces or arc surfaces. A limiting groove 8.1 is arranged on one surface (inclined surface or arc surface) of the protrusion 8. Preferably, the limiting groove 8.1 is a V-shaped limiting groove, which includes a first inclined surface 8.11 and a second inclined surface 8.12. The opening of the V-shaped limiting groove faces the limiting part 6.2, that is, the top of the first inclined surface 8.11 is higher than the bottom of the limiting part 6.2 to block the limiting part 6.2, and the second inclined surface 8.12 is lower than the limiting part 6.2 as a whole so that the limiting part 6.2 can enter the V-shaped limiting groove. In this embodiment, after the first pipe 1 and the second pipe 2 are connected into the connecting cylinder 3, the abutting member 6 is rotated to be horizontal as a whole. Since there is no additional limiting, the driving cylinder 4 is synchronously rotated by rotating the manual cylinder 5, the abutting member 6 is rotated by rotating the driving cylinder 4, and the limiting part 6.2 of the abutting member 6 enters the V-shaped limiting groove and is blocked by the first inclined surface 8.11 to abut during the rotation process. Therefore, the driving cylinder 4 is also limited so that it cannot be synchronously rotated with the manual cylinder 5. Subsequently, the abutting process described above can be realized by rotating the manual cylinder 5.
[0034] Further, the second inclined surface 8.12 is provided with a locking groove, that is, a locking groove is provided on the groove wall (the second inclined surface 8.12) of the V-shaped limiting groove, and after the limiting part 6.2 abuts against the first inclined surface 8.11 or enters the abutting state, the limiting part 6.2 is manually pressed downward to enter the locking groove. The purpose of such arrangement is that the buried pipeline may self-rotate and loosen to cause leakage due to various reasons during long-term use, and the limiting part 6.2 enters the locking groove to prevent reverse rotation, thereby achieving self-locking.
[0035] Further, in the embodiment, the first inclined surface 8.11 is inclined relative to the diameter line of the first pipeline 1, and the first inclined surface 8.11 is inclined away from the diameter line passing through the top (one end away from the axis of the first pipeline 1) to the bottom, and the part of the limiting part 6.2 abutting against the first inclined surface 8.11 is parallel to the first inclined surface 8.11. In the foregoing embodiment, the manual pressing operation of the limiting part 6.2 is complicated, and it is difficult to operate after abutting, and the construction personnel may not operate at all. In the embodiment, due to the inclination of the first inclined surface 8.11, when the limiting part 6.2 abuts against the first inclined surface 8.11, the limiting part 6.2 is passively moved downward due to the rotation force, and is automatically clamped into the locking groove, that is, no additional force is required, the rotation thread cooperation process is also the self-locking stroke of the limiting part 6.2, and due to the inclination of the first inclined surface 8.11 and the double limiting of the locking groove, the locking is extremely stable and passive throughout.
[0036] The foregoing merely describes some exemplary embodiments of the present application by way of illustration, and it is needless to say that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present application. Therefore, the foregoing drawings and descriptions are illustrative in nature, and should not be construed as limiting the scope of protection of the claims of the present application.
