[0025] The connecting structure 4 comprises a functional plate 401 fixedly installed on the outer wall of the connecting ring 2, the functional plate 401 is rotationally installed with a limiting clamping plate 402 through a rotating shaft, a vertical plate 403 is fixedly installed on the surface of the functional plate 401, an inner shaft 404 is fixedly installed on the surface of the vertical plate 403, a torsional spring 405 is fixedly installed on the surface of the inner shaft 404, a fixed plate 406 is fixedly installed on the surface of the branch pipe 3, a clamping rod 407 is fixedly installed on the side of the fixed plate 406 facing the limiting clamping plate 402, and a push rod 408 is hingedly connected to the side of the limiting clamping plate 402 away from the fixed plate 406.

[0026] The heat-resistant assembly 9 comprises a fixed frame 901 fixedly installed in the inner portion of the main pipe 1, a shunt hole plate 903 is fixedly installed on the front end of the fixed frame 901, and a fan blade 902 is rotationally installed on the rear end of the fixed frame 901.

[0027] As shown in Figure 1 and Figure 5 shown, by setting the protective sleeve 5, and the protective sleeve 5 comprises two arc-shaped plates, and the two arc-shaped plates are fixed through fastening bolts, in use, the main pipe 1 is wrapped through the two arc-shaped plates, then the two arc-shaped plates are fixed through the fastening bolts, and the sound insulation cotton arranged in the interior can play the effect of sound insulation and noise reduction.

[0028] As shown in Figure 1 and Figure 6 shown, by setting the filter box 6, the through hole and the filter screen 8, in use, the through hole is convenient for the pipeline to extend to the interior of the filter box 6, the filter screen 8 is convenient for filtering the impurities in the sewage, and the sealing ring 10 achieves the effect of sealing the pipeline.

[0029] As shown in Figure 1 and Figure 6 shown, by setting the cleaning assembly 7, and the cleaning assembly 7 comprises a horizontal plate 701, a mounting plate 702, a micro motor 703 and a brush plate 704, when the surface of the filter screen 8 needs to be cleaned, the plug rod 705 is inserted into the slot in the filter box 6, so that the horizontal plate 701 is fixed on the top of the filter box 6, then the brush plate 704 can be attached to the filter screen 8, then the micro motor 703 is started, the micro motor 703 drives the brush plate 704 to rotate, the impurities on the surface of the filter screen 8 are adhered and swept away, and the clean water source can be used to flush the impurities in the filter box 6.

[0030] As shown in Figure 4As shown, by setting the heat-resistant assembly 9, the water flow is effectively dispersed through the shunt orifice plate 903, thereby increasing the contact area between the water flow and the air, which can significantly reduce the temperature of the water flow. The impact of the water flow causes the fan blade 902 to rotate, further enhancing the flow of air, thereby accelerating the loss of heat. This design enables the PVC drainage pipe to effectively disperse heat under high temperature conditions, reducing the risk of damage to the PVC material due to heat, thereby prolonging its service life. By optimizing the heat exchange between the water flow and the air, the drainage pipe exhibits higher safety and reliability in actual application.

[0031] It should be particularly noted that the inner layer of the main pipe 1 and the branch pipe 3 uses heat-resistant material polypropylene (PP), which has good heat resistance and can withstand high temperatures.

[0032] In implementation, the following steps are performed:

[0033] 1) First, separate the connecting ring 2 from the branch pipe 3 by pulling the push rod 408 outward, which drives the limiting clamping plate 402 to rotate;

[0034] 2) Then, when the limiting clamping plate 402 rotates, the fixed plate 406 loses its limiting function, thereby causing the connecting ring 2 and the branch pipe 3 to lose their limiting function, completing the separation. When the branch pipe 3 needs to be connected to the connecting ring 2, the push rod 408 is also pulled outward;

[0035] 3) Pull the branch pipe 3 towards the inside of the connecting ring 2, and stop moving when the surface of the sealing ring is tightly attached to the outer wall of the connecting ring 2. Then, release the push rod 408, which is driven by the torsion of the torsional spring 405 to rotate the limiting clamping plate 402, causing the clamping rod 407 on the surface of the fixed plate 406 to be clamped into the clamping groove inside the limiting clamping plate 402;

[0036] 4) Finally, the connecting ring 2 and the branch pipe 3 are fixed, and the above operation is repeated to fix the main pipe 1 and the connecting ring 2, thereby completing the connection of the main pipe 1 and the branch pipe 3.

[0037] In summary, the PVC drainage pipe with high heat resistance, by setting the connecting structure 4, through the cooperation of the functional plate 401 and the limiting clamping plate 402, by connecting and fixing the limiting clamping plate 402 and the fixed plate 406, the branch pipe 3, the main pipe 1 and the connecting ring 2 are fixed, and the main pipe 1 and the branch pipe 3 are connected. Through the above setting, without using flanges, the connection effect between pipes can be achieved, thereby simplifying the disassembly and assembly process.

[0038] And, the PVC drainage pipe fitting with high heat resistance effect, by setting heat resistance assembly 9, through the cooperation of fixing frame 901 and fan blade 902 etc., makes the device can effectively disperse heat under high temperature condition, reduces the risk of heat damage of PVC material, and further prolongs its service life, optimizes the heat exchange of water flow and air, makes the drainage pipe fitting show higher safety and reliability in actual application.
