Description

Technical Field

[0001] This utility model relates to the field of indoor drainage pipes, and in particular to an embedded part for secondary drainage process of mortar layer in wet areas. Background Technology

[0002] The field of indoor drainage pipes covers the entire process of building internal drainage systems, while secondary drainage technology is a key measure for waterproofing wet areas. The two are technically connected through "embedded parts"—the secondary drainage process of wet area mortar layer uses embedded parts (such as secondary drainage floor drains, diversion pipes, etc.) as core components, which are pre-embedded in the mortar leveling layer during the construction stage. They are specifically used to collect and drain water that has seeped into the waterproof layer. Together with the main drainage pipes that drain from the ground surface, they form a double protection system, effectively solving the problem of leakage in wet areas. This is an important technical node for improving the waterproofing reliability of indoor drainage systems.

[0003] The working principle of embedded parts in the secondary drainage process of wet mortar layers is to pre-embed drainage pipes or facilities within the wet mortar layer. These embedded parts guide water along a predetermined drainage path, effectively draining accumulated water from the wet area and preventing leakage or dampness caused by water retention. This design improves the drainage efficiency of the mortar layer, prevents moisture buildup, ensures the dryness and stability of the building structure, and reduces the damage of moisture to building materials.

[0004] In existing technologies, some embedded parts used in secondary drainage processes for mortar layers in wet areas lack overflow prevention mechanisms. During the drainage process, they are easily affected by pressure fluctuations in the main pipeline or poor drainage, leading to sewage overflow into the mortar layer or accumulation in the pipeline. This results in reduced drainage efficiency, blockage, and potential leakage, significantly diminishing the water drainage function of the secondary drainage process and becoming a technical bottleneck restricting the reliability of waterproofing in wet areas. Therefore, a new type of embedded part for secondary drainage processes in mortar layers in wet areas is proposed to solve the above problems. Utility Model Content

[0026] Reference Figure 1 , Figure 4 , Figure 5 This utility model provides an embodiment of an embedded component for secondary drainage of mortar layers in wet areas. The component includes a guide pipe 1, which is a core component of the entire device. The guide pipe 1 guides water flow to the drainage path. An installation shaft 2 is fixedly connected to the outside of the guide pipe 1, connecting it to a detachable filter mechanism to ensure the stability of the entire device. A positioning shaft 5 is fixedly connected to the bottom of the installation shaft 2, providing stable axial support within the device and ensuring the fixed positions of the guide pipe 1 and the detachable filter mechanism. The detachable filter mechanism is slidably connected to the outside of the positioning shaft 5. Its main function is to filter impurities in the water flow, preventing large particles from entering the guide pipe 1 and affecting drainage performance. An anti-overflow mechanism is fixedly connected to the bottom of the guide pipe 1, designed to prevent water from overflowing back into the wet mortar layer and ensuring unidirectional flow in the drainage system.

[0027] The overflow prevention mechanism includes a support shaft 10, which is slidably connected to the outside of the guide pipe 1 to provide support for the overflow prevention mechanism. The support shaft 10 is slidably connected to the outside of the guide pipe 1, and a connecting shaft 11 is rotatably connected to the inside of the support shaft 10. The connecting shaft 11 is stably connected to the support shaft 10 by engaging with a locking tooth and a locking groove, and can be threaded to a fixed shaft 13 to ensure the sealing of the overflow prevention mechanism. The support shaft 10 has a locking groove inside, and the connecting shaft 11 has locking teeth on the outside. The locking teeth are rotatably connected to the inside of the locking groove. The connecting shaft 11 is threaded to a fixed shaft 13, which provides axial stability and is externally connected to the sealing assembly. The sealing assembly includes multiple compression springs 15 to ensure a good sealing effect between the fixed shaft 13 and the valve ball 9. The sealing assembly is fixedly connected to the outside of the fixed shaft 13, and a sealing ring 12 is fixedly connected to the top of the fixed shaft 13. The sealing ring 12 contacts the inner wall of the coupling groove of the support shaft 10 to effectively prevent water backflow and ensure the reliability of the sealing system. The valve ball 9 is slidably connected inside the support shaft 10. The function of the valve ball 9 is to prevent overflow water from entering the guide pipe 1 and ensure the normal operation of the drainage system. The bottom of the valve ball 9 contacts the top of the connecting shaft 11. A coupling groove is opened at the bottom of the support shaft 10, and the outside of the sealing ring 12 contacts the inner wall of the coupling groove.

[0028] The sealing assembly includes multiple compression springs 15. The adjacent sides of the multiple compression springs 15 are fixedly connected to the inside of the fixed shaft 13, and the distant sides of the multiple compression springs 15 are fixedly connected to compression blocks 16. The compression springs 15 and compression blocks 16 adjust the pressure of the sealing assembly through elasticity to ensure the continuity and stability of the sealing effect. A sealing gasket 14 is slidably connected inside the fixed shaft 13. The contact between the sealing gasket 14 and the external water pipe forms an effective sealing layer to prevent water leakage. The inner side of the sealing gasket 14 contacts the outer side of the compression block 16. A cavity is opened inside the fixed shaft 13. The outer side of the compression springs 15 is fixedly connected to the inside of the cavity, and the outer side of the compression block 16 is slidably connected to the inside of the cavity.

[0029] Reference Figures 1 to 3 The detachable filter mechanism includes a filter shaft 3, which serves to bear loads and rotate, and is internally slidably connected to the outside of a positioning shaft 5. The filter shaft 3 enables the filter device to smoothly filter the water flow. A locking shaft 4 is rotatably connected to the bottom of the filter shaft 3. The locking shaft 4 has a rotating groove inside, and the locking shaft 4 and the rotating groove work together to ensure the filter mechanism is securely fixed. A fixing tooth 6 is externally rotatably connected to the inside of the rotating groove. The outer side of the filter shaft 3 contacts the inner side of the rotating groove. A cotton block 7 is fixedly connected inside the filter shaft 3. The cotton block 7 serves as a filter medium, helping to adsorb impurities in the water flow and purify the water. The outer side of the filter shaft 3... A fixed tooth 6 is fixedly connected, which cooperates with the inner wall of the rotating groove to ensure the stable rotation of the filter shaft 3 and avoid deviation during the filtration process. A snap-fit ​​shaft 4 is rotatably connected to the outside of the filter shaft 3. A rubber pad 8 is fixedly connected to the bottom of the snap-fit ​​shaft 4. The rubber pad 8 is used to seal between the device and the ground to prevent water leakage and ensure the efficient operation of the filtration process. A water guide groove is opened on the outside of the guide pipe 1. The water guide groove is set on the outside of the guide pipe 1 to guide the water flow. The outside of the water guide groove is in contact with the inside of the kapok block 7, and the outside of the water guide groove is in contact with the inner wall of the support shaft 10.

[0030] Working principle: By rotating the connecting shaft 11 inside the support shaft 10 and sliding the valve ball 9 on the support shaft 10, overflow of drainage is prevented. When the support shaft 10 does not need to be filled with water, the valve ball 9 can isolate the odor of the sewer, thereby improving the practicality of the device. The fixed shaft 13 threaded to the outside of the connecting shaft 11 cooperates with the sealing component located outside the fixed shaft 13 to enhance the sealing of the device, thereby reducing the leakage of sewer odor.

[0031] The support shaft 10 and the fixed shaft 13 are connected to the externally reserved drain pipe. During this process, the drain pipe squeezes the sealing gasket 14, causing the sealing gasket 14 to contract and exert a squeezing force on the squeezing block 16 and the squeezing spring 15, thereby making the surface of the sealing gasket 14 fit tightly with the drain pipe, thus achieving the fixing of the sealing box.

[0032] The rubber pad 8, fixed to the bottom of the snap-fit ​​shaft 4, is in contact with the ground. The rubber material of the rubber pad 8 allows for fine adjustment, enabling the device to adapt to uneven ground and improve its practicality. Meanwhile, the filter shaft 3, rotatably connected to the top of the snap-fit ​​shaft 4, performs coarse filtration of the water flow, preventing mortar from flowing into the device and affecting the drainage effect. The rotatable connection of the filter shaft 3 also allows for subsequent maintenance. The positioning shaft 5, fixed to the bottom of the mounting shaft 2, provides restriction and positioning for the filter shaft 3. The guide pipe 1 drains water through the external water channel.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
