Description

Technical Field

[0001] The present invention relates to the technical field of ship power, and particularly to a particle damping vibration energy collection and integration device for a ship power system pipeline. Background Art

[0002] The power system is an important part of marine platforms such as ships. Fluid pipelines such as pumps and valves are common and critical structures in the ship power system. The main functions of the ship fluid pipeline network are to achieve fluid transportation and power transmission. For the high-energy pipelines in the power system, since equipment such as pumps, generators, steam turbines, and internal combustion engines will inevitably introduce excitation sources, and coupled with the coupling effect between the pipe wall and the fluid, pipeline vibration is often induced. At the same time, since the pipeline connects different system equipment, forming a bridge between the equipment, accessories, etc. and the ship hull, after the vibration and noise of various equipment excitation sources have been gradually and effectively controlled, the pump valve pipeline network has become the main vibration and noise transmission path. On the one hand, the pipeline vibration and noise affect the normal operation of the pipeline system, causing the pipeline connection accessories to loosen, and in severe cases, even causing fluid leakage and pipeline damage, seriously affecting the safe and reliable operation of the ship power system; on the other hand, the vibration and air noise in the limited space will seriously affect the cabin comfort, and even cause noise pollution, making it difficult to meet the requirements of green ships. Therefore, how to reduce the vibration and noise of ship pipelines has become the key to current research. Compared with land platforms, ship pipeline vibration reduction and noise reduction face problems such as narrow space and complex pipelines, making it difficult to implement vibration reduction measures, and limited adaptability of vibration reduction materials in harsh environments.

[0003] The particle damping technology has the characteristics of high temperature resistance, corrosion resistance, small required space, and convenient maintenance, and has broad application prospects in pipeline vibration reduction. The traditional planar particle damping vibration reduction technology is difficult to adapt to the complex pipeline structure of the ship power system. In addition, the excitation amplitude generated by pipeline vibration is limited, and the particles are prone to accumulation or agglomeration, making it difficult to fully exert the vibration reduction effect. At the same time, the traditional particle damping technology only realizes vibration energy consumption, and how to reasonably collect and utilize the vibration energy is also a problem that needs to be considered currently.

[0004] The information disclosed in this background art section is only intended to enhance the overall understanding of the present invention and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those of ordinary skill in the art.

Figure 2 is an enlarged structural schematic diagram of the first cavity 2 of the particle damping vibration energy collection and integration device for the pipeline of the ship power system according to an embodiment of the present invention.

[0024] like Figures 1 to 2 As shown, a particle damping vibration energy collection integrated device for a ship power system pipeline according to a preferred embodiment of the present invention includes: a body 1, a plurality of particle dampers 3, and a power circuit management module 4. The body 1 is wrapped around the pipeline, and a plurality of first cavities 2 are respectively opened on the left and right sides of the interior of the body 1. The plurality of particle dampers 3 are respectively filled in the plurality of first cavities 2. And the power circuit management module 4 is arranged outside the body 1, and the power circuit management module 4 is electrically connected to the plurality of first cavities 2 through a plurality of power lines 5. Among them, the material of the inner bottom surface 6 of the first cavity 2 and the material of the left and right inner wall surfaces 7 and the material of the inner top surface 8 are materials with different electrical polarities. Among them, when the pipeline vibrates, multiple particle dampers 3 and multiple particle dampers 3 and the inner bottom surface 6, left and right inner wall surfaces 7 and inner top surface 8 of the first cavity 2 rub against each other, thereby colliding to consume vibration energy. At the same time, the mutual friction between multiple particle dampers 3 and the inner bottom surface 6, left and right inner wall surfaces 7 and inner top surface 8 of the first cavity 2 can realize charge transfer, and the output electricity is transmitted to the power circuit management module 4 through multiple power lines 5.

[0025] In one embodiment of the present invention, an insulating layer 9 is disposed on the outer side of the inner bottom surface 6 of each first cavity 2 .

[0026] In one embodiment of the present invention, the particle damping vibration energy collection integrated device for the ship power system pipeline further includes a base 10 fixed to the wall of the ship cabin, and the body 1 is fixed on the base 10 .

[0027] In one embodiment of the present invention, the particle damping vibration energy collection integrated device for the ship power system pipeline further includes a data transceiver chip 11 , and the data transceiver chip 11 is electrically connected to the power circuit management module 4 .

[0028] In one embodiment of the present invention, a second cavity 12 is defined on the upper side of the body 1 .

[0029] In one embodiment of the present invention, the particle damping vibration energy collection integrated device for the ship power system pipeline also includes a sensor 13, which is arranged in the second cavity 12, and the sensor 13 is electrically connected to the power circuit management module 4 and the data transceiver chip 11 respectively.

[0030] In one embodiment of the present invention, the particle damping vibration energy collection integrated device for the pipeline of the ship power system also includes an alarm device electrically connected to the data transceiver chip 11.

[0031] In one embodiment of the present invention, the volume ratio of the plurality of particle dampers 3 in each first cavity 2 is 0.2 to 0.5.

[0032] In an embodiment of the present invention, the upper surface and the lower surface of each first cavity 2 are both bent downward, and the central angle corresponding to the curved surface is greater than 10° to 30°.

[0033] In an embodiment of the present invention, the data transceiver chip 11 is used to collect the signals of the power circuit management module 4 and the sensor 13. When the vibration or temperature signal exceeds the threshold, the data transceiver chip 11 sends a warning signal to the warning device.

[0034] In practical applications, the particle damping vibration energy collection and integration device for the ship power system pipeline of the present invention combines the particle damping 3 technology and the triboelectric power generation technology. On the one hand, the particle damping 3 dissipates to reduce the vibration and noise of the pipeline, and on the other hand, the vibration energy of the pipeline is collected through the charge transfer between the particles and the electrode material to supply energy to the sensor 13 and the chip, simplifying the system and realizing energy recovery.

[0035] The particle damping 3 vibration energy collection device (body 1) is arranged in a body-fitting manner along the periphery of the pipeline. The particle damping 3 vibration energy collection device is annularly coated around the pipeline. The inner sides of the particle damping 3 vibration energy collection device are divided into a plurality of first cavities 2. A certain amount of particle damping 3 is filled in the first cavities 2. The bottom surface material of the first cavity 2 and the materials of the cavity peripheral surface and the top surface are materials with different electrode polarities. There is an insulating layer 9 separating between the two first cavities 2. When the pipeline vibrates, the particle damping 3 rubs and collides with each other and with the cavity wall surface to consume part of the vibration energy to achieve the purpose of vibration reduction. At the same time, the charge transfer is realized during the contact and separation process between the particle damping 3 and the cavity wall surface, so as to have a certain power output ability.

[0036] Particle damping 3 is placed in the cavities on both sides of the pipeline. It is recommended that the volume ratio of the particle damping 3 in the cavity is 0.2 - 0.5. The surface material of the particle damping 3 and the cavity wall surface material have different electronegativities so that charge transfer occurs during the contact and separation process between the particle damping 3 and the wall surface. The commonly used materials for the surface of the particle damping 3 are polyester, polyvinyl alcohol, etc.

[0037] The bottom surface material of the first cavity 2 and the materials of the cavity periphery and the top surface are materials with different electrode polarities. The difference in their electrode polarities is as large as possible, and it is different from the electrode polarity of the particle damping 3. The material close to the pipe wall surface is an insulating material, and the upper and lower bottom surface materials are separated by an insulating material.

[0038] The upper and lower surfaces of the first cavity 2 are both bent downward. The central angle corresponding to the curved surface is preferably in the range of 10 - 30°. When the pipeline vibrates, the upper and lower bottom surfaces deform, causing the particles to vibrate. The bottom surface is fully conducive to stroke amplification, thereby amplifying the excitation amplitude, strengthening the particle vibration, and enhancing the vibration reduction and charge transfer capabilities. The electric energy collected by the particle damper 3 vibration energy collection device is transmitted to the power circuit management module 4, and the power circuit management module 4 includes a capacitor, a rectifier bridge, etc. Particles damper 3 is not placed in the upper and lower second cavities 12 of the pipeline, and vibration, temperature or flow sensors 13 are provided, and the energy required by them is provided by the power circuit management module 4.

[0039] The power circuit management module 4 also provides electric energy to the data transceiver chip 11. The data transceiver chip 11 is a low-power chip. The data transceiver chip 11 collects the signals of the power circuit management module 4 and the sensor 13. When signals such as vibration / temperature exceed a certain threshold, the data transceiver chip 11 sends a warning signal to the control and warning system. The outer wall surface of the particle damper 3 and the vibration energy collection device is connected to the base 10 or the hanger and is fixed to the wall surface of the ship's cabin.

[0040] As Figure 1 shown, the body 1 is arranged around the pipeline in a body-fitting manner. The left and right sides of the body 1 are divided into a plurality of first cavities 2, that is, the particle damper 3 vibration energy collection cavities. A certain number of damping particles are placed in each cavity. When the pipeline vibrates, the excitation is transmitted to the particle damper 3 vibration energy collection device, and the stroke is amplified through the bottom arc displacement amplification mechanism. The particle vibration is strengthened, the dissipation effect of the particle damper 3 is enhanced, and at the same time, the collision between the particles and the wall is strengthened, and the vibration energy collection ability is enhanced. The electric energy collected by the particle damper 3 vibration energy collection device is transmitted to the power circuit management module 4, and is converted by the power circuit management module 4 into a frequency and amplitude suitable for the sensor 13 and the data transceiver chip 11 to supply energy to the sensor 13 and the data transceiver chip 11. Damping particles are not suitable to be arranged in the upper and lower second cavities 12, and vibration sensors 13 are placed. When the signal of the sensor 13 exceeds the standard, the data transceiver chip 11 sends data to the warning device; the entire body 1 is arranged on the base 10 and is connected to the wall surface of the cabin.

[0041] As Figure 2 shown, a certain number of damping particles are placed in the first cavity 2. The surface material of the damping particles has different electronegativities from the bottom surface and the wall surface, and is between the electronegativities of the bottom surface, the top surface and the peripheral wall surface. The difference in electronegativity between the material of the bottom surface and the top surface is as large as possible. The bottom surface bending structure constitutes an arc displacement amplification mechanism to amplify the vibration excitation, so that the collision between the particles and the wall and between the particles is intensified, the effect of the particle damper 3 is strengthened, and the vibration energy is gradually dissipated, realizing the enhancement of the vibration reduction and noise reduction function. On the other hand, due to the difference in electronegativity between the particles and the wall, charge transfer is realized through the collision between the particles and the wall, thereby realizing the conversion of vibration energy into electric energy.

[0042] The present invention arranges the particle damping and vibration energy harvesting device in a body-attached manner to the pipeline, overcoming the weakness that the planar particle damper is difficult to adapt to complex three-dimensional structures such as pipelines. The two-side cavities are separated to form small chambers, avoiding the particle accumulation in large chambers that may affect the vibration reduction effect. Through the arc-shaped arrangement of the bottom and top surfaces of the chambers, an arc displacement amplification mechanism is formed to strengthen the vibration excitation, further avoiding the occurrence of particle accumulation and agglomeration, strengthening the particle damping and vibration energy dissipation effects, and thus strengthening the vibration reduction and noise reduction. At the same time, by taking advantage of the difference in electronegativity between the surface material of the damping particles and the wall surface as well as between the wall surfaces, charge transfer is achieved through the collision between the damping particles and the wall surface, forming electric energy for functions such as the data transceiver chip 11 and the sensor 13, realizing the self-supply of energy and simplifying the arrangement.

[0043] In summary, the particle damping vibration energy harvesting and integration device for the pipeline of the ship power system of the present invention has a simple and reasonable structure, fits the pipeline arrangement body 1, divides the annular body 1 into multiple cavities, places particle damping 3 in the cavities, and the curved settings of the upper and lower wall surfaces of the cavities contribute to stroke amplification, thus amplifying the excitation, strengthening the vibration reduction effect of the particle damping 3 and the charge transfer ability; the charge transfer is realized by the collision between the particle damping 3 and the wall surface, thereby providing electric energy for the power circuit management module 4 and the sensor 13, achieving the multi-function integration of vibration reduction, self-power supply, signal transmission and warning, etc., and simplifying the system arrangement.

These descriptions are not intended to limit the present invention to the precise forms disclosed, and obviously, many changes and variations are possible in light of the above teachings.
