Description

Technical Field

[0001] The utility model relates to the technical field of drainage pipes, in particular to a drainage pipe with sound insulation and noise reduction functions. Background Art

[0002] Drainage pipes are mainly used for drainage. A large number of drainage pipes are required in building drainage. When a large amount of water or objects are poured into the sewer, the water flow speed will increase rapidly, resulting in high-speed flow in the pipe. This high-speed flow will generate pressure, causing impact and noise near the sewer outlet. The generation of noise not only affects the comfort of the living environment but may also have an impact on the quality of life.

[0003] After retrieval, the patent document with the publication number CN218094733U discloses a drainage pipe provided with a sound insulation structure. By arranging a sound insulation cotton, a sound insulation pipe, connecting bolts and a heat-resistant pipe, during use, the sound insulation pipe and the heat-resistant pipe form a double-layer structure outside the drainage pipe body, and sound insulation cotton is assembled between the sound insulation pipe and the heat-resistant pipe. When draining water, the water flow inside the drainage pipe body will generate vibration. The sound insulation cotton is composed of multiple fiber holes. The sound generated by the vibration will be weakened in intensity after passing through the sound insulation cotton through countless reflections, superpositions and collisions, thereby weakening the intensity of the noise and realizing the function of sound insulation and noise reduction; by arranging a mounting plate, a bracket, a drainage pipe body, mounting bolts and mounting holes, during use, after placing the mounting plate at a designated place, pass the mounting bolts through the through holes at the mounting plate, and rotate the mounting bolts to install them in the holes reserved on the wall until the mounting bolts are rotated and tightened to complete the installation and fixation of the bracket. The structure is relatively simple and convenient to operate.

[0004] When the above-mentioned drainage pipe is actually used, since the sound insulation cotton and the sound insulation pipe are sleeved on the drainage pipe body, the sound insulation cotton is easily mildewed and fails after being affected by external water vapor. During subsequent maintenance, it needs to be replaced as a whole, resulting in a high cost. Since multiple threaded connection methods are used, it is more cumbersome to replace and not conducive to operation. Content of the Utility Model

Specific embodiments

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some, rather than all, embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0022] As Figures 1 - 4 shown, it relates to a drainage pipe with sound insulation and noise reduction function, including a drainage pipe body 1. One end of the drainage pipe body 1 is provided with a receiving pipe orifice 2. The receiving pipe orifice 2 is welded to one end of another drainage pipe body 1 to realize the docking of multiple drainage pipe bodies 1. An annular groove is opened on the inner wall of the receiving pipe orifice 2, and a sealing ring 3 is placed on the inner wall of the annular groove.

[0023] A sound insulation cotton 4 is sleeved on the outer wall of the drainage pipe body 1. The sound insulation cotton 4 is made of existing rock wool, has elasticity and sound insulation effect. At the same time, existing shock-absorbing springs can be added to buffer the drainage pipe body 1. Two semi-circular pipe sleeves 5 are sleeved on the outer wall of the sound insulation cotton 4. A plurality of plug-in blocks 6 are uniformly fixedly connected to the outer walls of the two semi-circular pipe sleeves 5. A plurality of plug-in holes 7 are uniformly formed in the outer walls of the two semi-circular pipe sleeves 5. The two semi-circular pipe sleeves 5 are butted by sliding the plug-in blocks 6 into the plug-in holes 7 to form a pipe. Multiple semi-circular pipe sleeves 5 and sound insulation cotton 4 can be arranged at multiple places on the drainage pipe body 1 to wrap the drainage pipe body 1.

[0024] A plurality of pressing pieces 8 are fixedly connected to the inner walls of the two semi-circular pipe sleeves 5. The outer walls of the plurality of pressing pieces 8 are all pressed against the outer wall of the sound insulation cotton 4. The plurality of pressing pieces 8 are in a triangular structure to fix the sound insulation cotton 4 on the outer wall of the drainage pipe body 1. The outer walls of the two semi-circular pipe sleeves 5 are sleeved with the same hoop 9. The hoop 9 is divided into two parts as a whole and is locked by two existing bolts and nuts to fix the two semi-circular pipe sleeves 5 on the drainage pipe body 1. A rubber gasket 10 is fixedly connected to the inner wall of the hoop 9. The rubber gasket 10 is in contact with the two semi-circular pipe sleeves 5.

[0025] A connecting mechanism is arranged on the outer wall of the hoop 9. The connecting mechanism includes a connecting rod 11. One end of the connecting rod 11 is fixedly connected to the outer wall of the hoop 9. A connecting sleeve 12 is slidably sleeved on the outer wall of the connecting rod 11. One end of the connecting rod 11 is fixedly connected with a round block 13. The outer wall of the round block 13 is slidably connected with the inner wall of the connecting sleeve 12.

[0026] A spring 14 is fixedly connected inside the connecting sleeve 12. One end of the spring 14 is fixedly connected to the outer wall of the round block 13. The spring 14 is in a compressed state in the connecting sleeve 12 and always remains in contact with the round block 13. When the hoop 9 is vibrated, the spring 14 plays a certain buffering role, and the friction force between the round block 13 and the connecting sleeve 12 is used as damping. One end of the connecting sleeve 12 is fixedly connected with a pre-embedded gasket 15. A plurality of pre-embedded holes are formed in the outer wall of the pre-embedded gasket 15. After the pre-embedded gasket 15 is pre-embedded and fixed, the position of the connecting sleeve 12 and the connecting rod 11 is fixed, so as to fix the position of the hoop 9 and the sound insulation cotton 4.

[0027] Working principle: When multiple drainage pipe bodies 1 are in use, multiple drainage pipe bodies 1 are welded at one end through the receiving pipe orifice 2 with one end of another drainage pipe body 1, and the sealing ring 3 is used as an error compensation to avoid gaps. When multiple drainage pipe bodies 1 are arranged vertically, they are fixed to the concrete through existing reserved holes, and when arranged horizontally, they are fixed by hoisting; when the drainage pipe body 1 is sound-insulated, the sound-insulating cotton 4 is wound around the outer wall of the drainage pipe body 1, and then the two ends of the sound-insulating cotton 4 are glued together. Then, the two semi-circular pipe sleeves 5 are aligned with each other so that the insertion blocks 6 and the insertion holes 7 between them cooperate with each other to form a pipe integral body to protect the sound-insulating cotton 4 and facilitate replacement. At this time, multiple pressing pieces 8 press and limit the sound-insulating cotton 4 and fix it in the two semi-circular pipe sleeves 5 to prevent sliding. At the same time, the hoop 9 is sleeved on the two semi-circular pipe sleeves 5, and then the hoop 9 is fixed on the two semi-circular pipe sleeves 5 through two existing bolts. The rubber gasket 10 prevents direct contact between the hoop 9 and the two semi-circular pipe sleeves 5. The position of the embedded gasket 15 is adjusted by rotating the connecting sleeve 12 through the connecting rod 11 to facilitate installation on the wall or equipment. At the same time, when the drainage pipe body 1 vibrates, the sound-insulating cotton 4 is made of rock wool and has a certain buffering and sound-insulating effect through its own fiber structure, reducing the noise generated when the drainage pipe body 1 is in use.
