Description

Technical Field

[0001] This utility model relates to the field of drainage pipe technology, and in particular to a self-insulating phosphogypsum composite drainage pipe. Background Technology

[0002] Using industrial byproduct phosphogypsum as a base material, its mechanical properties are enhanced through modification, and a multifunctional drainage pipe is formed by composite functional layers. Its core feature is the integration of drainage, corrosion resistance, and thermal insulation functions through a multi-layered structure, making it suitable for underground drainage systems in low-temperature or high-temperature environments.

[0003] Utilizing the lightweight and fire-retardant properties of phosphogypsum as the main structural support, a composite foamed insulation layer reduces heat exchange between the fluid inside the pipe and the environment; an anti-corrosion layer isolates external corrosive media; and a flexible waterproof layer prevents leakage. This multi-layered approach achieves structural stability, long-lasting insulation, and impermeability and corrosion resistance. However, pipe connections are inconvenient, requiring frequent adjustments for positioning and installation, making installation less efficient. Therefore, we propose a self-insulating phosphogypsum composite drainage pipe to address these issues. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a self-insulating phosphogypsum composite drainage pipe.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-insulating phosphogypsum composite drainage pipe, comprising a composite pipe, a docking seat, a clamping arm insert, a positioning pin, and a pressure ring. The docking seat has composite pipes at both ends, and inserts slidably installed inside the composite pipes are provided at both the upper and lower ends of the docking seat. Positioning pins arranged in a circular array are provided at both the upper and lower ends of the docking seat. Positioning holes and travel holes arranged in a circular array and in a cross-shaped pattern are provided inside the composite pipes. A second pin hole is provided inside the positioning pin, and a second clamping pin is slidably inserted into both the travel hole and the second pin hole. A circular groove is provided inside the docking seat, and a rotating shaft arranged in a circular array is rotatably installed inside the groove. A clamping arm is provided at one end of the rotating shaft, and a torsion spring with both ends connected to the clamping arm and the circular groove is sleeved on the outside of the rotating shaft.

[0006] The outer wall of the card arm is provided with equidistant anti-slip textures.

[0007] Preferably, the outer wall of the second locking pin and the inner wall of the first pin hole are conical. When the conical second locking pin enters the second pin hole through the stroke hole, it applies an increasing compressive force between the inner walls of the second pin hole, thus achieving a sliding installation between the second locking pin and the second pin hole.

[0008] Preferably, the inner walls at both the upper and lower ends of the insertion tube are provided with flow guiding surfaces. The liquid being transported inside the composite tube is guided by the flow guiding surfaces, which helps the flow of the discharged fluid and avoids fluid interception.

[0009] Preferably, a threaded sleeve is threadedly fitted onto the outer wall of the mating seat, and a pressure ring with a tapered inner wall is provided at the lower end of the threaded sleeve. When the threaded sleeve rotates on the outer wall of the composite pipe, it drives the pressure ring to compress the locking pin.

[0010] Preferably, the threaded sleeve and the mating seat have pin holes arranged in a ring array inside, and each pin hole has a retaining pin slidably inserted into it. The retaining pin is inserted into the pin hole to position the threaded sleeve.

[0011] Preferably, a side ring is fitted onto the outer wall of the threaded sleeve, and a spring is provided at the lower end of the side ring. A limiting ring, fitted onto the outer side of the threaded sleeve, is provided at the lower end of the spring. The side ring supports the upper end of the spring, and the elastic force of the spring acts on the limiting ring, which limits the locking pin.

[0012] Preferably, a ball bearing is rotatably mounted on the inner wall of one end of the locking pin, and a fitting groove is provided on the upper end of the outer wall of the insertion tube and the docking seat, with a rubber sleeve inside the fitting groove. When the pressure ring squeezes the locking pin, the ball bearing reduces wear and resistance on the contact surface. When the docking seat connects with the insertion tube and the composite tube, the rubber sleeve is squeezed to improve the sealing of the contact surface.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This utility model relates to a composite pipe that is connected via a docking seat. The small-diameter insertion rods at the upper and lower ends of the docking seat are inserted into the interior of the composite pipe. The two sets of insertion rods are fixed inside the composite pipe, so that the composite pipe is located at both ends of the docking seat. The composite pipe is positioned during installation. The outer side of the clamping arm box is rotated by a torsion spring for elastic support. The clamping arm supports the inner wall of the installation space, which improves the stability of the docking seat and makes it convenient to position and install the composite pipe.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-5 As shown, the present invention proposes a self-insulating phosphogypsum composite drainage pipe, comprising a composite pipe 1, a docking seat 2, a clamping arm 4, an insert 8, a positioning pin 15, and a pressure ring 22. The docking seat 2 is provided with composite pipes 1 at both ends. The docking seat 2 is provided with inserts 8 that are slidably installed inside the composite pipe 1 at both the upper and lower ends. The docking seat 2 is provided with positioning pins 15 arranged in a ring array at both the upper and lower ends. The composite pipe 1 is provided with positioning holes 19 and stroke holes 12 arranged in a ring array and in a cross pattern inside. The positioning pins 15 are provided with pin holes 16. The stroke holes 12 and pin holes 16 are slidably inserted with clamping pins 18. The docking seat 2 is provided with a ring groove 3. The ring groove 3 is rotatably installed with a rotating shaft 10 arranged in a ring array inside. One end of the rotating shaft 10 is provided with a clamping arm 4. The outside of the rotating shaft 10 is sleeved with a torsion spring 9 that is connected to the clamping arm 4 and the ring groove 3 at both ends respectively.

[0023] The outer wall of the card arm 4 is provided with equidistant anti-slip textures 11;

[0024] The outer wall of pin 218 and the inner wall of pin hole 21 are conical.

[0025] The inner walls of both the upper and lower ends of the insertion tube 8 are provided with flow guiding surfaces 7;

[0026] The threaded sleeve 20 is installed on the outer wall of the docking seat 2. The lower end of the threaded sleeve 20 is provided with a pressure ring 22 with a conical inner wall.

[0027] The threaded sleeve 20 and the mating seat 2 have pin holes 21 arranged in a ring array inside, and each pin hole 21 has a locking pin 17 slidably inserted inside.

[0028] A side ring 24 is fitted onto the outer wall of the threaded sleeve 20. A spring 14 is provided at the lower end of the side ring 24. A limiting ring 13 is fitted onto the outer side of the threaded sleeve 20 at the lower end of the spring 14.

[0029] The inner wall of the locking pin 17 is rotatably installed with a ball bearing 23, and the upper end of the outer wall of the insertion tube 8 and the docking seat 2 are both provided with a fitting groove 5, and a rubber sleeve 6 is provided inside the fitting groove 5.

[0030] Based on the implementation steps of Example 1: When actually laying the self-insulating phosphogypsum composite drainage pipe, the operation process is as follows: First, place the docking seat 2 between the two composite pipes 1 to be connected, so that the insertion tubes 8 at the upper and lower ends of the docking seat 2 are aligned with the docking ports of the two composite pipes 1 respectively. Slowly push the docking seat 2 so that the insertion tubes 8 are gradually inserted into the composite pipe 1. During the insertion process, the outer wall of the insertion tube 8 is tightly attached to the inner wall of the composite pipe 1. At the same time, the guide surface 7 of the inner wall at the upper and lower ends of the insertion tube 8 can guide the small amount of liquid or impurities that may remain in the pipe, so as to avoid them from hindering the insertion of the insertion tube 8. As the insertion tube 8 goes deeper, the positioning pins 15 distributed in a ring array at the upper and lower ends of the docking seat 2 will gradually enter the positioning holes 19 opened inside the composite pipe 1 to complete the initial positioning guidance.

[0031] Meanwhile, as the positioning pin 15 enters the positioning hole 19, the pin hole 16, which is located inside the stroke hole 12 and the positioning pin 15, inserts the locking pin 18. It is subjected to the force of the internal structure of the docking seat 2, such as a pushing device that may be triggered by a specific tool or structure later. Although it is not explicitly mentioned in the text, it can be reasonably inferred based on the overall design logic that the locking pin 18, which is conical in shape, slides from the stroke hole 12 into the pin hole 16 and fits tightly against the inner wall of the pin hole 16, thereby achieving the lateral locking of the docking seat 2 and the composite tube 1.

[0032] After the positioning pin 15 is fully inserted into the positioning hole 19, the locking operation begins. The threaded sleeve 20 connected to the threaded sleeve 20 on the outer wall of the docking seat 2 is rotated. During the rotation, the threaded sleeve 20 moves downward along the outer wall of the docking seat 2, causing the pressure ring 22 with a conical inner wall at its lower end to move downward synchronously. During the downward movement, the pressure ring 22 causes the pressure ring 22 to limit the outer side of the second locking pin 18, and the locking pin 17, which is slidably inserted into the first pin hole 21, contacts the pin. As the pressure ring 22 continues to press down, the locking pin 17 is squeezed by the conical pressure ring 22, overcomes the elastic resistance of the spring 14, and slides outward along the first pin hole 21 until the locking pin 17 is inserted into the corresponding position on the inner wall of the composite tube 1, thus achieving the initial axial fixation of the docking seat 2 and the composite tube 1.

[0033] After the above connection operation is completed, the clamping arm 4, which was originally rotating into the docking seat 2 under the elastic support of the torsion spring 9, will be squeezed by the inner wall of the installation space since the docking seat 2 has been installed in place. The outer wall of the clamping arm 4 will be tightly fitted with the inner wall of the installation space. The anti-slip texture 11 on the outer wall of the clamping arm 4 can increase the friction with the inner wall, thereby providing additional support for the docking seat 2 and improving the stability of the entire drain pipe docking structure.

[0034] The drainage pipe is initially positioned by inserting the insertion pipe 8 into the composite pipe 1. The positioning pin 15 and the positioning hole 19 are used to ensure the docking accuracy. The threaded sleeve 20 and the docking seat 2 are used to drive the pressure ring 22 to squeeze the locking pin 17. Combined with the elastic action of the spring 14, axial fixation is achieved. The sliding insertion of the locking pin 28 in the stroke hole 12 and the pin hole 26 achieves radial locking. At the same time, with the elastic support of the torsion spring 9, the locking arm 4 supports the inner wall of the installation space after installation, enhancing the structural stability. The design of the insertion pipe 8, the positioning pin 15 and the composite pipe 1, as well as the automatic locking mechanism of the locking pin 17 and the locking pin 2 18, greatly simplifies the pipe docking process, reduces the time for frequent position and positioning adjustments, and improves installation efficiency. The dual axial and radial locking, as well as the additional support of the locking arm 4, make the pipe connection more secure and can effectively withstand external pressure and vibration, ensuring the stable operation of the drainage system.

[0035] The rubber sleeve 6 inside the fitting groove 5 is compressed during the docking process, which improves the sealing of the mating surface, prevents liquid leakage, and ensures the normal use of the drainage pipe. This solves the problem of low installation efficiency caused by the inconvenience of docking traditional phosphogypsum composite drainage pipes, which require frequent adjustments to position and install. By using snap-fit ​​positioning, elastic locking, and boltless connection, the pipe can be quickly and accurately docked and stably installed, improving construction efficiency and quality.

[0036] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
