Description

Technical Field

[0001] This invention belongs to the field of pipeline vibration control, and specifically relates to a modular intelligent pipeline support. Background Technology

[0002] The design and selection of pipe supports and hangers are crucial components of pipeline system design. They are used to withstand pipeline mass and loads, control pipeline displacement and vibration, and reduce the transmission of pipeline vibration to the installation foundation, finding wide application in vibration reduction and isolation. However, with continuous technological advancements, traditional pipe supports and hangers have certain shortcomings in engineering applications, primarily manifested in their limited functionality, failing to meet increasingly demanding engineering requirements.

[0003] Taking the nuclear power industry as an example, pipe supports are widely used in the piping systems of nuclear power plants to reduce the damage caused by pipe vibration to the installation foundation and the pipes themselves, thereby reducing the risk of safety accidents. Currently, metal spring supports or polymer material supports are commonly used in the nuclear power industry. They perform well in terms of pipe restraint and vibration control, but their functions are limited and they cannot perform real-time testing of the vibration control status of the pipelines and supports themselves. Therefore, nuclear power plants invest a lot of manpower and physical resources in the daily inspection of nuclear power pipelines.

[0004] In addition, existing pipe supports and hangers are only suitable for isolating broadband vibrations caused by pipe vibrations, and are difficult to manage line spectrum vibrations, which have a significant impact on safety indicators such as the tightness of the threaded connections of supports and hangers.

[0005] In practical engineering applications, the feasibility of replacing different functions is particularly important for equipment or components with more functions, and this is also true for supports and hangers. When enriching the functions of supports and hangers, modular design should be adopted according to different functions. When a single functional module fails or is damaged, or when there are other types of parameter changes required, each functional module can be quickly replaced, avoiding the time loss caused by returning to the factory or reprocessing.

[0006] Based on the above analysis, developing a modular intelligent pipe support that simultaneously possesses line spectrum vibration absorption and condition monitoring functions is crucial for addressing the issue of the limited functionality of existing pipe supports. Summary of the Invention

[0007] The purpose of this invention is to integrate dynamic vibration absorption technology, vibration energy harvesting technology, and online monitoring technology into the design of traditional pipeline supports in a modular manner for practical engineering applications. It also integrates key structural designs to develop a modular intelligent pipeline support. While retaining the boundary constraints and vibration control functions of existing pipeline supports, it adds modular devices that integrate dynamic vibration absorption, energy harvesting, vibration monitoring, anomaly alarms, and wireless communication functions. This solves the problems of existing pipeline supports having limited functionality, being unable to effectively handle pipeline spectrum vibrations, and requiring significant manpower and resources for daily safety inspections. Its core technology lies in utilizing a cantilever beam-mass block structure to provide targeted dynamic vibration absorption reaction force, effectively controlling pipeline spectrum vibrations; using piezoelectric materials to convert the mechanical energy generated during the cantilever beam vibration process into electrical energy, thereby powering the online monitoring module; and using sensors to collect support vibration signals in real time, thus realizing the monitoring and analysis of support vibrations.

[0008] The objective of this invention is achieved as follows:

[0009] A modular intelligent pipe support includes a support body, a sensor, a vibration signal acquisition and analysis alarm module, and a dynamic vibration absorption module.

[0010] The support frame body is a cylindrical structure, including a mounting base, a hinge connection, a shell connecting rod, an upper cover plate, a shell body, a spring, a T-shaped connector, a lower cover plate, a pipe clamp, and a pipe. The upper cover plate, the shell body, and the lower cover plate are fixedly connected to form a shell. One end of the shell connecting rod is fixedly connected to the upper cover plate, and the other end is connected to the mounting base through a hinge connection. The spring is installed between the lower cover plate and the horizontal axis of the T-shaped connector. The vertical axis of the T-shaped connector passes through the lower cover plate, and the lower end of the vertical axis is fixedly connected to the pipe through a pipe clamp.

[0011] The dynamic vibration absorption module is mounted on the upper end of the horizontal axis of the T-shaped connector via a module mounting base; the dynamic vibration absorption module includes an electric power management system, a cantilever beam, a piezoelectric material, and an oscillator mass block; the electric power management system is fixed on the module mounting base, the cantilever beam is fixed on the electric power management system, the oscillator mass block is fixed at the edge end of the cantilever beam, and the piezoelectric material is attached and fixed to the surface of the cantilever beam;

[0012] The number of sensors is two, which are respectively installed on the dynamic vibration absorption module and the upper cover plate, and are used to collect vibration signals from the pipe end and the base end of the pipe support;

[0013] The dynamic vibration absorption module is connected to the vibration signal acquisition, analysis, and alarm module via a cable, providing it with power. The vibration signal acquisition, analysis, and alarm module is fixed to the outer casing and includes a signal acquisition system, a signal processing and analysis system, an alarm system, a wireless transmission system, and a display screen. The signal acquisition system is connected to the sensor via a signal line, transmitting the raw analog signals acquired by the sensor to the signal processing and analysis system for post-processing of the vibration signals. The signal processing and analysis system then transmits the processed signals to the alarm system, the wireless transmission system, and the display screen. The alarm system selects and triggers an audible and visual alarm based on the digital signal. The wireless transmission system transmits the received signals to the main control room, and the display screen displays the received signals in real time.

[0014] The specific parameters of the cantilever beam and the vibrator mass block need to be designed and calculated using the finite element method or analytical method to ensure that the first-order frequency of the dynamic vibration absorption module is consistent with the vibration frequency.

[0015] The alarm system, wireless transmission system, and display screen operate independently and can be adjusted to standby or on state according to actual needs.

[0016] The power management system optimizes the system's energy acquisition efficiency, and after voltage boosting, outputs and stores the generated DC power to power subsequent cable and vibration signal acquisition, analysis, and alarm modules.

[0017] The advantages of this invention are:

[0018] Compared to traditional pipe supports, this invention further enhances the functionality of pipe supports. While maintaining the original broadband vibration reduction function of the supports, it introduces dynamic vibration absorption function and online vibration signal acquisition and analysis function. It realizes the modular design and integration of dynamic vibration absorption module, energy harvesting module, and vibration signal acquisition, analysis and alarm module, which greatly improves the engineering application value of pipe supports.

[0019] Compared to traditional energy harvesting technologies, this invention achieves a fusion design of dynamic vibration absorption technology and vibration energy harvesting technology in pipeline supports and hangers. The cantilever beam provides the function of an elastic element, and the piezoelectric material plays the role of a damping element. The cantilever beam-piezoelectric material-mass block structure realizes the coexistence and structural integration of dynamic vibration absorption and energy harvesting functions, which is not available in existing pipeline supports and hangers.

[0027] The invention will now be described in more detail with reference to the accompanying drawings:

[0028] like Figure 1 and Figure 4 As shown, a modular intelligent pipe support includes a support body, a sensor 4, a vibration signal acquisition and analysis alarm module 7, and a dynamic vibration absorption module 8.

[0029] The main function of the support body is the same as that of a traditional support, used to support the pipeline and reduce the transmission of vibration at both ends of the support through springs. The outer shell is a cylindrical structure, including an upper cover plate 5, an outer shell 6, and a lower cover plate 12, which are fixed together in sequence by screws or welding. One end of the outer shell connecting rod 3 is fixed to the upper cover plate 5, and the other end is connected to the mounting base 1 through a hinge connection 2. The spring 10 is installed between the lower cover plate 12 and the horizontal axis of the T-shaped connecting rod 11. The lower end of the vertical axis of the T-shaped connector 11 is fixed to the pipeline 14 through a pipe clamp 13.

[0030] Figure 2 A schematic diagram of the dynamic vibration absorption module is given. The dynamic vibration absorption module 8 is installed on the upper end of the horizontal axis of the T-shaped connector through the module mounting base 9.

[0031] The dynamic vibration absorption module includes an electrical management system 8-1, a cantilever beam 8-2, a piezoelectric material 8-3, and a vibrator mass block 8-4. The electrical management system 8-1 is fixed to the module mounting base 9, the cantilever beam 8-2 is fixed to the electrical management system 8-1, the vibrator mass block 8-4 is fixed to the edge of the cantilever beam 8-2, and the piezoelectric material 8-3 is adhered and fixed to the surface of the cantilever beam. In specific engineering applications, the piezoelectric material 8-3 must be fixed to the cantilever beam 8-2 by bonding or other means to maximize its damping effect. The specific parameters of the cantilever beam 8-2 and the vibrator mass block 8-4 need to be designed and calculated using the finite element method or analytical method to ensure that the first-order frequency of the dynamic vibration absorption module is consistent with the vibration frequency, thus avoiding failure of the dynamic vibration absorption module.

[0032] When the dynamic vibration absorption module 8 is working, the cantilever beam 8-2, piezoelectric material 8-3, and vibrator mass block 8-4 form a vibration energy harvesting system. The vibration of the pipeline drives the vibrator mass block 8-4 to vibrate, causing the cantilever beam 8-2 and the piezoelectric material 8-3 on its surface to bend, generating electricity through the piezoelectric effect. After the power management system 8-1 optimizes the system's energy harvesting efficiency and boosts the voltage, the generated DC power is output and stored to power the subsequent load circuits.

[0033] Figure 3 A schematic diagram of the functional composition of the vibration signal acquisition and analysis alarm module is given. The dynamic vibration absorption module 8 is connected to the vibration signal acquisition and analysis alarm module 7 via a cable and is powered by it. The vibration signal acquisition and analysis alarm module 7 is fixed on the outer shell 6 and includes a signal acquisition system 7-1, a signal processing and analysis system 7-2, an alarm system 7-3, a wireless transmission system 7-4, and a display screen 7-5. The signal acquisition system 7-1 is connected to the sensor 4 via a signal line. Two sensors 4 are installed on the dynamic vibration absorption module 8 and the upper cover plate 5, respectively, to collect vibration signals from the pipe supports and bases. The signal acquisition system 7-1 transmits the collected raw analog signals to the signal processing and analysis system 7-2 for post-processing of the vibration signals, including analog-to-digital conversion, filtering, integration, and FFT (Fast Fourier Transform). The signal processing and analysis system 7-2 transmits the processed digital signals to the alarm system 7-3, the wireless transmission system 7-4, and the display screen 7-5. The alarm system 7-3 evaluates the received digital signals; if they meet the alarm conditions (e.g., vibration exceeding limits), it triggers an audible and visual alarm. The wireless transmission system 7-4 can further transmit the received signals to the main control room, enabling operators to monitor the vibration of pipes at various locations in real time. The display screen 7-5 displays the received signals in real time at the pipe supports, facilitating timely access to pipe vibration information by inspection personnel.

[0034] In actual use, the alarm system 7-3, the wireless transmission system 7-4, and the display screen 7-5 should operate independently and can be adjusted to standby or on state according to actual needs, so as to make reasonable use of the power provided by the power vibration absorption module 8.

[0035] In actual use, the connection between the dynamic vibration absorption module, the energy harvesting module and the vibration acquisition module is made by screws or threads to facilitate module replacement or maintenance.

[0036] It should be noted that although the accompanying drawings of this invention only show the implementation principle and the relative installation positions of each core component, those skilled in the art can complete the detailed design of each core component based on the structural schematic diagram shown in this invention. Therefore, any related changes made to the design details of each core component based on this invention (including but not limited to the form of the piezoelectric vibration energy harvester, bolt connection method, spring selection change, overall layout design, etc.) are all within the protection scope of this invention.
