Description

Technical Field

[0001] The present invention relates to the field of intelligent drainage systems, and more particularly to a HDPE silent drainage pipe system for building drainage. Background Art

[0002] With the increasing density of urban buildings and residents' growing concern for the comfort of their living environment, the performance of building internal drainage systems has become a crucial aspect of modern architectural design that cannot be ignored. Drainage noise is one of the key issues affecting building comfort. Traditional building drainage systems are mostly constructed of plastic pipes such as high-density polyethylene (HDPE), polypropylene (PP), or polyvinyl chloride (PVC), which offer certain advantages in terms of structural strength and chemical corrosion resistance. However, these pipes are prone to water impact and turbulent shock waves during the drainage process, which can easily cause structure-borne noise. This is especially noticeable when used at night or in high-rise continuous drainage environments, causing significant interference to users' lives and work.

[0003] To reduce noise generated by drainage systems, some products have been optimized by increasing pipe wall thickness, adding outer coatings (such as rubber or foam), and improving installation methods. Some companies have also developed three-layer co-extruded noise-reducing pipes, which achieve a certain degree of quieting through a smooth inner layer, a sound-absorbing interlayer, and a supporting outer layer. However, these methods primarily rely on "passive noise reduction" in their structure and still have the following limitations:

[0004] 1. The noise reduction effect depends on the physical properties of the material and is subject to the thickness of the structure and the accuracy of construction;

[0005] 2. It is impossible to achieve real-time feedback and active regulation of drainage status;

[0006] 3. Lack of system-level linkage capabilities, unable to form overall coordination of intelligent buildings;

[0007] 4. Once a pipeline is clogged or operating abnormally, it usually requires regular manual inspections or user subjective perception, resulting in delayed response and low maintenance efficiency.

[0008] On the other hand, with the rapid development of smart and green buildings, the intelligence level of building infrastructure continues to improve, and traditional drainage systems, which are "structure-centric," are becoming increasingly outdated. Users and managers have higher expectations for drainage systems: not only must they be silent, efficient, and stable, but they also want them to be "visualized, controllable, predictable, and interconnected," transforming drainage systems from "passive pipes" to "active response systems."

[0009] Therefore, there is an urgent need to develop a new type of HDPE silent drainage pipe system for building drainage. On the basis of continuing the advantages of the traditional pipe noise reduction structure, it integrates the sensor module and control terminal to realize the intelligent silent drainage solution of hardware and software integration to meet the comprehensive requirements of modern buildings in terms of comfort, safety, intelligence and maintenance efficiency. Summary of the Invention

[0010] In order to solve the above problems, the present invention provides a HDPE silent drainage pipe system for building drainage. The system integrates the physical structure with digital intelligent control to form a "soft and hard combination" collaborative architecture. On the basis of maintaining the strength and durability of the drainage structure, it improves its noise reduction effect, operation visualization level and remote operation and maintenance capabilities, thereby meeting the comprehensive requirements of modern buildings for the quietness, intelligence and maintenance efficiency of the drainage system.

[0011] To achieve the above objectives, the present invention provides the following technical solutions, which mainly include:

[0012] The drainage pipe system of the present invention is mainly composed of two subsystems: the physical pipe structure module and the intelligent perception control module:

[0013] 1. Physical pipeline structure module:

[0014] This module is the basic part of the system, and its core structure includes:

[0015] Outer pipe: Made of high-density polyethylene (HDPE), it forms the main pressure-bearing support body and has good impact resistance and corrosion resistance. It can withstand the impact of water flow and external pressure in the building's internal drainage system.

[0016] Inner pipe: Installed inside the outer pipe and fixedly connected to it via a coaxial sleeve. The inner pipe is made of low-density modified HDPE material with good flexibility. The surface is attached with spiral or strip-shaped guide ribs to guide the water flow in a stable direction, reduce turbulence and water hammer, and thus reduce structure-borne sound sources.

[0017] Connection port: It adopts modular quick-plug structure, which is convenient for quick assembly on site, and also reserves sensor access slots to improve the future expansion capability;

[0018] Mounting rail: Molded on the outer surface of the outer tube, it provides a fixed interface for standardized sensors and smart modules, with high compatibility and layout flexibility.

[0019] 2. Intelligent perception control module:

[0020] To monitor and intelligently respond to drainage status, this system integrates multiple sensing and control technologies, including:

[0021] Sensing module: It is composed of various types of sensors such as water flow, temperature and humidity, noise, and pressure. It can be installed at the pipe connection port or node and communicate with the central processing platform wirelessly.

[0022] Noise sensor: It is designed to capture noise data during pipeline operation in real time and compare it with the preset silence threshold for noise anomaly identification and alarm;

[0023] Central Control Platform: This is the core controller of the system and can be located at the device level or remotely in the cloud. This platform integrates data acquisition, analysis, alarm logic, and remote interface functions, enabling comprehensive monitoring of drainage status and issuing control commands through local or remote terminals.

[0024] The control platform and pipeline sensor modules achieve real-time interconnection and interoperability through communication protocols such as LoRa, NB-IoT, or Wi-Fi, and support the following functions:

[0025] Real-time status monitoring: including drainage volume, noise level, temperature and humidity environment changes, etc.

[0026] Intelligent control function: can be linked to intelligent valves to adjust the drainage path or throttling ratio according to water pressure and flow rate;

[0027] Remote early warning and repair reporting: When noise or water flow anomalies are detected, the system automatically pushes alarms to the management platform or user terminal;

[0028] Data analysis and trend forecasting: Establish a historical database through long-term operating data to provide a basis for subsequent operation and maintenance and energy-saving scheduling.

[0029] It can be seen from the above technical solution that compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. Significantly improve drainage noise reduction performance: The present invention adopts a double-layer HDPE pipe structure, and the inner pipe is provided with spiral guide ribs, which can effectively guide the stable flow of water, reduce turbulence and backflow, and reduce the noise caused by the collision of water flow and pipe wall; at the same time, the outer pipe provides good structural support and sound insulation effect, and the overall noise reduction ability is better than the traditional single-layer structure or drainage pipe without guide design.

[0031] 2. Intelligent management of the drainage system: By integrating intelligent components such as noise sensors, water flow sensors, and temperature and humidity sensors into the pipeline structure, and coordinating with a central control platform for unified data collection and analysis, the system can monitor the drainage operation status in real time, automatically identify and issue early warnings for problems such as abnormal noise, blockage trends, and water pressure fluctuations, thereby improving system response speed and operation and maintenance efficiency.

[0032] 3. Constructing an intelligent drainage system that combines software and hardware: This invention not only achieves physical noise reduction at the structural level, but also has data processing, control instruction issuance, trend modeling and remote access functions at the software system level. It breaks through the limitations of traditional drainage systems that "only drain and do not care", and forms a closed-loop control capability with deep integration of structural systems and software systems.

[0033] 4. Good scalability and integration: The system is pre-installed with mounting rails and standard communication interfaces, which facilitate the later integration of additional modules such as smart valves, rainwater recovery, and water quality monitoring according to project requirements. It also supports seamless integration with building automation systems and building information modeling (BIM) platforms to achieve data linkage and visual management of the entire building drainage system.

[0034] 5. Easy installation and simplified maintenance: The modular quick-install interface and embedded sensor installation structure allow for rapid deployment or replacement of sensor equipment without damaging the pipeline. The installation rail and integrated structure simplify the construction process, reduce the wiring and debugging costs of traditional systems, and make maintenance operations more convenient and efficient.

[0035] Through the above technical solutions and system architecture, the present invention effectively solves the problems of unstable noise reduction effect, unknown operating status, and delayed maintenance response in existing building drainage systems, significantly improves the quietness, safety, intelligence and management efficiency of the drainage system, and has good engineering adaptability and promotion and application value.

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] Example:

[0041] like Figure 1 As shown, the present invention provides a HDPE silent drainage pipe system for building drainage. The overall structure of the system consists of a pipe structure body and an intelligent monitoring and control platform. The two work together to build a building drainage management system that combines software and hardware to achieve structural noise reduction and intelligent control of operating status during the drainage process.

[0042] The pipeline structure of the present invention includes the following main components:

[0043] Outer tube 1: This hollow cylindrical tube is made of high-density polyethylene (HDPE), offering excellent compressive strength and corrosion resistance, capable of withstanding high water pressure and acidic and alkaline corrosive environments within buildings. Multiple preformed mounting rails 5 are located on the outer wall of the outer tube to secure various sensor modules and intelligent monitoring devices, enabling modular installation and deployment and enhancing system scalability.

[0044] Inner tube 2: This coaxial hollow pipe is positioned within outer tube 1. Made of low-density modified HDPE, it offers excellent flexibility and low noise transmission. Spiral guide ribs 3 are located on the inner wall of the inner tube. These ribs are arranged in a spiral pattern along the flow direction. These ribs not only guide the flow along a stable path, preventing turbulence, but also act as a buffer and diverter during water impacts, significantly reducing structure-borne noise caused by water impact and bubble bursting.

[0045] Connector 4: This quick-connect structure is provided between adjacent pipe sections. It features a quick-plug design with an embedded flexible sealing ring and a snap-on retaining mechanism, ensuring a secure and leak-proof connection, preventing leaks and water hammer. A slot is provided within the connector for mounting a noise sensor 7 and a sensor module 8.

[0046] Noise sensor 7: A highly sensitive digital pickup device is used to monitor noise changes caused by water flow in the pipe in real time, quantifying the noise signal as data and uploading it to the central control platform 6. The sensor can be installed at connection ports 4, pipe corners, or the outlet of a shaft, where strong water flow disturbances are likely to occur. It should have a certain degree of moisture and dust resistance.

[0047] Sensor module 8: It is a multifunctional integrated sensing unit, including water flow sensor, temperature and humidity sensor, pressure sensor, etc. It can be flexibly configured according to different monitoring needs. The module housing has an IP67 protection grade and is suitable for a variety of indoor and outdoor installation environments.

[0048] Central Control Platform 6: This serves as the data center and command distribution center for the entire system. It can be deployed in a building equipment room, property monitoring room, or integrated into a building intelligence platform. The platform includes embedded processing chips and data storage modules, along with a communication gateway, control interface, and human-machine interface. It supports the aggregation, analysis, and response control of sensor data from all pipeline sections.

[0049] The actual operation process of the system is as follows:

[0050] After drain liquid is injected into the piping system from the upper floors, it first enters the inner cavity of inner pipe 2 and flows downward in a spiral or steady pattern, guided by guide ribs 3. Because the guide ribs mitigate the direct impact of the water on the inner wall and effectively reduce the "echo-like" vibration noise caused by the drop of the water column in the empty pipe, low noise levels are maintained even in high-flow, continuous drainage scenarios.

[0051] During pipeline operation, sensor module 8 continuously collects information about flow velocity, temperature, humidity, and air pressure within the current pipe segment, and periodically uploads this data to central control platform 6 via wireless communication. If the sensor detects signals such as continuous noise exceeding a threshold, sharp fluctuations in flow velocity, or localized pressure anomalies, the central platform intelligently identifies these as potential blockages, undivided liquid and gas flow, or poor drainage. It can then activate intelligent electric valves, bypass pipelines, or issue an alarm to alert property management personnel.

[0052] At the same time, this system supports real-time graphical interface presentation, and can remotely view drainage status diagrams, pipeline operation trends, alarm records and other content through desktop terminals or mobile application platforms, realizing data closed-loop management from "perception-identification-response".

[0053] During the construction and deployment phase, the piping system of this invention boasts exceptional engineering adaptability. All pipe sections, connectors, and sensors utilize a standard modular design. Pre-defined guide rails and insert interfaces allow for rapid assembly and disassembly, eliminating the need for secondary drilling or welding. The sensor modules utilize a snap-on or slide-type fit with the guide rails, facilitating precise positioning during construction and subsequent maintenance and replacement.

[0054] Furthermore, the system can optimize zoning design based on factors such as building height and hydraulic load distribution. For example, in a multi-story building, primary monitoring nodes can be set up in vertical main pipelines, while auxiliary data collection devices can be installed in branch drainage pipelines. The platform then conducts horizontal comparative analysis based on data from each monitoring point, thereby identifying potential local overloads or drainage blind spots within the building.

[0055] This system is suitable not only for ordinary residential buildings but also for buildings with higher noise control requirements, such as hospitals, schools, libraries, and hotels. For large commercial complexes or municipal drainage corridors, expansion modules can also be used to introduce rainwater monitoring, water quality analysis, remote automatic flushing, and other functions, enabling more extensive drainage data management and intelligent scheduling.

[0056] For example, in a hospital ward building, when the drainage pipes on a certain floor produce noise due to frequent use at night, the system can automatically identify the abnormal frequency, close or limit the discharge rhythm of some valves through cloud linkage, or prompt the property to adjust the drainage peak plan to effectively avoid disturbing patients' rest.

[0057] Another advantage of this system is its excellent data traceability and maintainability. All collected data is stored locally and synchronized with the cloud. Periodic data statistics can be used to analyze high-noise areas, peak drainage load periods, and pipeline aging trends, providing a quantitative basis for pipeline system maintenance planning. After long-term operation, the platform can also output a "health assessment report" that scores the overall status of the building's drainage system and provides optimization recommendations.

[0058] In summary, this embodiment demonstrates an HDPE silent drainage pipe system that deeply integrates structural innovation and intelligent perception. It has high noise reduction capability, high scalability and high intelligence level, meets the comprehensive technical requirements of current and future smart building and green building drainage systems, and has extremely high practical value and market application prospects.
