Description

Technical Field

[0001] This application relates to the technical field of ship exhaust pipe connection, and more particularly to a ship exhaust pipe connection device and a ship. Background Technology

[0002] Ship exhaust pipes generate high-frequency vibrations averaging around 20Hz due to the vibrations of the main and auxiliary engines and the high-temperature exhaust pulse waves. Currently, most ships use rubber elastic hangers and supports for passive damping to reduce vibration energy. Because most ships have a large number of exhaust pipes and long lines, hundreds of such damping components need to be installed.

[0003] Currently, damping-like components used in ship connections are typically only intended to mitigate the vibration energy generated by exhaust pipes. This vibration energy is usually dissipated naturally by the damping-like components themselves, leaving the exhaust pipe's vibration energy largely unutilized. Summary of the Invention

[0004] The purpose of this invention is to provide a connection device for a ship's exhaust pipe and a ship, which can solve the above-mentioned problems existing in the prior art.

[0005] To achieve the above objectives, this application adopts the following technical solution: On the one hand, a connection device for a ship exhaust pipe is provided, comprising: a first connection device and / or a second connection device, and an energy harvesting unit; Both the first connecting device and the second connecting device include: The first connecting unit is connected to the hull of the ship and is fixed relative to the hull of the ship. The second connecting unit is connected to the exhaust pipe and is fixed relative to the exhaust pipe; and An energy conversion unit, connected to the first connection unit and the second connection unit, is used to convert mechanical energy into electrical energy; The energy harvesting unit is electrically connected to the energy conversion unit and is used to collect and store the electrical energy generated by the energy conversion unit. When the exhaust pipe vibrates, displacement can occur between the first connecting unit and the second connecting unit, and the mechanical energy generated during the displacement can be converted into electrical energy by the energy conversion unit and collected and stored by the electrical energy collection unit.

[0006] Preferably, the first connecting device is disposed below the exhaust pipe and between the ship, and the first connecting device is used to support the exhaust pipe.

[0007] Preferably, in the first connecting device: The first connecting unit includes a base, which is fixedly connected to the ship; The second connecting unit includes a connecting plate, which is fixedly connected to the exhaust pipe; and The energy conversion unit includes a first sleeve and a second sleeve, a cavity is provided between the first sleeve and the second sleeve, and the cavity is filled with piezoelectric material. The first sleeve is fixedly connected to the base, and the second sleeve is fixedly connected to the connecting plate, and the first sleeve and the second sleeve are slidably connected.

[0008] Preferably, the second connecting device is disposed above the exhaust pipe and between the ship, and the second connecting device is used to hoist the exhaust pipe.

[0009] Preferably, in the second connecting device: The first connecting unit includes a connecting angle steel, which includes a steel body A and a steel body B that are perpendicular to each other. The steel body A is fixedly connected to the ship, and the steel body B is connected to the energy conversion unit. The energy conversion unit includes a first conversion module, which comprises: A first sleeve and a second sleeve, wherein the first sleeve is symmetrically connected to both sides of the steel body B, and the second sleeve is slidably sleeved on the first sleeve; The cavity between the first sleeve and the second sleeve is filled with piezoelectric material; The steel body B is slidably connected to a connecting rod, and the two second sleeves located on both sides of the steel body B are fixedly connected to the connecting rod. The second connecting unit includes a connecting plate, which is fixedly connected to the connecting rod, and the connecting plate is fixedly connected to the exhaust pipe.

[0010] Preferably, the energy conversion unit further includes a second conversion module, which includes: A housing, fitted onto the connecting rod, and fixedly disposed relative to the connecting plate; and An electromagnetic component includes a magnet rotor and a coil. The magnet rotor is located inside the housing and is rotatably connected to the connecting rod, and the coil is disposed around the magnet rotor and is fixedly connected to the inner wall of the housing. When the magnet rotor rotates, a current can be generated in the coil.

[0011] Preferably, it also includes a flywheel, which is fixedly connected to the magnet rotor.

[0012] Preferably, a sealing element for sealing is provided at the connection between the housing and the connecting rod.

[0013] Preferably, a clamp for fixing the exhaust pipe is fixedly connected to the connecting plate.

[0014] On the other hand, this disclosure also provides a vessel that includes a connection device for the vessel exhaust pipe as described in any of the preceding claims.

[0015] The beneficial effects of this application are as follows: By incorporating two different structural forms—a first connecting device and a second connecting device—the versatility of connection methods for the exhaust pipe is enhanced. This allows the exhaust pipe to be connected in appropriate ways under different environments. The first connecting device supports the exhaust pipe from below via a base, while the second connecting device is hoisted from above via connecting angle steel. This two-way collaborative action can withstand complex operating conditions such as shipboard turbulence and engine exhaust pulsation, preventing the exhaust pipe from sagging, shifting, or colliding with surrounding components, thus ensuring the exhaust system's sealing and structural integrity.

[0016] Both the first and second connecting devices integrate a sliding fit structure, which allows the sliding structure to absorb some of the vibration energy when the exhaust pipe vibrates, preventing the vibration from being directly transmitted to the hull body. This protects vulnerable parts such as exhaust pipe welding points and interfaces, reduces hull vibration noise, and improves the overall operational stability of the ship.

[0017] By using a sleeve to relatively slide and compress the piezoelectric material, adapting to the linear vibration of the exhaust pipe, the mechanical energy of linear displacement is directly converted into electrical energy; and by using vibration to drive the magnetic rotor to rotate, causing the coil to cut magnetic field lines, adapting to the oscillating / rotational vibration of the exhaust pipe. It is evident that this dual-principle approach creates "no dead angle" energy capture, avoiding energy loss under a single principle and significantly improving the vibration energy recovery rate.

[0018] Meanwhile, the eccentric flywheel in the second conversion module utilizes inertial characteristics to convert intermittent, low-amplitude vibrations into continuous, high-speed rotor kinetic energy. This amplifies the intensity of the coil cutting magnetic field lines, buffers vibration instability, and adapts to low-amplitude, high-frequency vibrations.

[0019] By storing the converted electrical energy through an energy harvesting unit, the ship's "idle vibration energy" is transformed into usable clean energy. Subsequently, it can power the ship's low-power equipment as needed, reducing dependence on the ship's main power supply, reducing fuel consumption and carbon emissions, which is in line with the energy optimization development trend of green ships and has both environmental value and energy benefits.

[0023] To make the technical problems solved, the technical solutions adopted, and the technical effects achieved by this application clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0026] like Figure 1 and Figure 2 As shown, this embodiment provides a connection device for a ship's exhaust pipe, which provides support and shock absorption between the exhaust pipe and the hull, while converting the vibration mechanical energy of the exhaust pipe into electrical energy for storage, thereby improving the energy utilization rate of the exhaust pipe's vibration mechanical energy.

[0027] Specifically, the connecting device for a ship's exhaust pipe disclosed herein includes a first connecting device 10 and / or a second connecting device 20. The first connecting device 10 and the second connecting device 20 have the same functional modules, but there are certain differences in their specific structures. For a ship's exhaust pipe, multiple first connecting modules and / or second connecting modules are connected. By setting multiple connecting modules, the utilization rate of the mechanical energy of the exhaust pipe's vibration can be improved.

[0028] It should be noted that both the first connecting device 10 and the second connecting device 20 include a first connecting unit 100 for connecting the ship's hull, a second connecting unit 200 for connecting the exhaust pipe, and an energy conversion unit 300 for converting mechanical energy into electrical energy, and the energy conversion unit 300 is connected between the first connecting unit 100 and the second connecting unit 200.

[0029] Furthermore, the exhaust pipe connection device provided in this disclosure also includes an energy harvesting unit 30, which is electrically connected to the energy conversion unit 300. When the exhaust pipe vibrates, displacement can occur between the first connection unit 100 and the second connection unit 200, and the mechanical energy generated during the displacement can be converted into electrical energy by the energy conversion unit 300, and collected and stored by the energy harvesting unit 30.

[0030] Understandably, the cooperation between the first connecting unit 100 and the second connecting unit 200 provides stable support for the exhaust pipe, ensuring its installation reliability during ship navigation. Simultaneously, the structural characteristics absorb exhaust pipe vibrations, reducing the impact of vibrations on the hull structure, the exhaust pipe itself, and surrounding equipment, preventing component wear, loosening, or malfunctions caused by long-term vibrations, and ensuring the overall stability of the ship's operation.

[0031] The exhaust pipe generates continuous vibration during operation. The energy conversion unit 300 directly converts the mechanical energy of the relative displacement between the first connecting unit 100 and the second connecting unit 200 during vibration into electrical energy. This converts idle vibration energy during ship operation into usable electrical energy, improving the overall energy utilization efficiency of the ship.

[0032] The converted electrical energy is collected and stored by the power harvesting unit 30, which avoids the loss of converted electrical energy and ensures that the energy can be retained so that it can be used to power low-power equipment on the ship as needed.

[0033] Specifically, in one embodiment, the power harvesting unit 30 adopts a layered modular architecture, receiving the electrical energy output from the piezoelectric and electromagnetic conversion unit in the ship's exhaust pipe connection device. After processing, it powers low-power devices and adapts to complex ship operating conditions. The power harvesting unit 30 includes an input interface layer, a power processing layer, an energy storage layer, an output power supply layer, and a structural protection layer. The input interface layer is equipped with branch interfaces and a busbar. The branch interfaces are used to adapt to piezoelectric low-frequency AC and electromagnetic high-frequency AC, realizing the aggregation of multiple power sources. The power processing layer converts AC to stable DC through bridge rectification, two-stage voltage regulation, and LC filtering. The energy storage layer mainly uses lithium iron phosphate battery packs for storage, with supercapacitors assisting in storing instantaneous energy, and is equipped with protection ICs to prevent overcharging, over-discharging, and short circuits. The output power supply layer is equipped with multiple interface specifications, such as USB-A, terminal type, and emergency interface. A low-power MCU monitors the power level in real time and adjusts the power supply priority. The structural protection layer uses an ABS shell and a fixing bracket with shock-absorbing pads to adapt to the high humidity, oil pollution, and strong vibration environment of the engine room. In typical operation, piezoelectric and electromagnetic energy are rectified and regulated before being stored in the storage unit. The MCU supplies power to sensors, indicator lights and other devices as needed. The overall modular design facilitates maintenance and is compatible with multiple connected devices for parallel input, efficiently realizing the recovery and utilization of vibration energy.

[0034] Please see Figure 1 In one embodiment, the first connecting device 10 is disposed below the exhaust pipe and between the vessel, and the first connecting device 10 is used to support the exhaust pipe.

[0035] Specifically, in the first connecting device 10, the first connecting unit 100 includes a base 101, which is fixedly connected to the ship. The second connecting unit 200 includes a connecting plate 102, which is fixedly connected to the exhaust pipe. For example, a clamp 1021 for engaging the exhaust pipe may be provided on the connecting plate 102, and by connecting the clamp 1021 to the exhaust pipe, a fixed connection between the exhaust pipe and the connecting plate 102 is achieved.

[0036] Furthermore, the energy conversion unit 300 includes a first sleeve 103 and a second sleeve 104, and a cavity is provided between the first sleeve 103 and the second sleeve 104, and the cavity is filled with piezoelectric material 105. It is understood that when relative sliding occurs between the first sleeve 103 and the second sleeve 104, the first sleeve 103 and the second sleeve 104 compress the piezoelectric material 105, causing the piezoelectric material 105 to generate electrical energy in the compressed state.

[0037] Specifically, the first sleeve 103 is fixedly connected to the base 101, and the second sleeve 104 is fixedly connected to the connecting plate 102, with a sliding fit between the first sleeve 103 and the second sleeve 104. Therefore, when the exhaust pipe vibrates, the first sleeve 103 slides relative to the second sleeve 104, thereby compressing the piezoelectric material 105. During the compression process, the piezoelectric material 105 generates electrical energy.

[0038] The first connecting device 10 supports the exhaust pipe, preventing it from shifting or swaying due to the ship's movement and ensuring the stability of the connection between the exhaust pipe and the overall ship structure. Simultaneously, the sliding fit design of the first sleeve 103 and the second sleeve 104 allows the sliding structure to absorb some of the vibration energy generated by the exhaust pipe due to engine operation or ship movement, reducing the direct transmission of vibration to the ship's body and protecting the exhaust pipe's own structure.

[0039] It is important to note that when the exhaust pipe vibrates, the relative sliding between the first sleeve 103 and the second sleeve 104 will compress the piezoelectric material 105 inside the cavity, directly converting the mechanical vibration energy into electrical energy using the piezoelectric effect. During the energy conversion process, the energy conversion through the piezoelectric material 105 is based on its own physical properties and does not require an external power source. This neither increases the ship's energy consumption nor alters the original exhaust function and support structure of the exhaust pipe, achieving "passive energy recovery" with advantages of low cost and easy maintenance.

[0040] Please see Figure 2 In one embodiment, the second connecting device 20 is disposed above the exhaust pipe and between the ship, and the second connecting device 20 is used for hoisting the exhaust pipe.

[0041] Specifically, in the second connecting device 20, the first connecting unit 100 includes a connecting angle steel 210, which includes a steel body A portion 211 and a steel body B portion 212 that are perpendicular to each other. The steel body A portion 211 is used to fix and connect the ship, and the steel body B portion 212 is used to connect the energy conversion unit 300.

[0042] Furthermore, the energy conversion unit 300 includes a first conversion module 310, which includes a first sleeve 103 and a second sleeve 104. The first sleeve 103 is symmetrically connected to both sides of the steel body B part 212, and the second sleeve 104 is slidably sleeved on the first sleeve 103. A cavity is provided between the first sleeve 103 and the second sleeve 104, and the cavity is filled with piezoelectric material 105. Therefore, when relative sliding occurs between the first sleeve 103 and the second sleeve 104, causing the cavity to shrink, the piezoelectric material 105 can be compressed, thereby generating electrical energy.

[0043] Furthermore, a connecting rod 106 is slidably connected to the steel body B part 212, and the two second sleeves 104 located on both sides of the steel body B part 212 are fixedly connected to the connecting rod 106.

[0044] The second connecting unit 200 is used to connect the exhaust pipe. Further, the second connecting unit 200 may include a connecting plate 102, and the connecting plate 102 is fixedly connected to the connecting rod 106, and the connecting plate 102 is fixedly connected to the exhaust pipe.

[0045] Therefore, when the exhaust pipe vibrates, the resulting displacement is transmitted to the second sleeve 104 via the connecting plate 102 and the connecting rod 106. As the exhaust pipe vibrates, the second sleeve 104 experiences relative displacement with the first sleeve 103. This allows the vibration generated by the exhaust pipe to be converted into electrical energy by the piezoelectric material 105.

[0046] The connecting angle steel 210 forms a rigid support frame through the mutually perpendicular steel body A part 211 and steel body B part 212. The mechanical properties of the angle steel are used to distribute the lifting load of the exhaust pipe, ensuring that the exhaust pipe is fixed in the vertical direction under complex working conditions such as ship sailing, turbulence and vibration. This avoids the exhaust pipe from sagging, shifting or colliding with surrounding components due to unstable lifting, thus ensuring the sealing and structural integrity of the exhaust system.

[0047] The first sleeve 103 is symmetrically arranged on both sides of the steel body B 212, and the second sleeves 104 on both sides are synchronously linked through the connecting rod 106, so that when the exhaust pipe vibrates, the sleeves on both sides can produce symmetrical relative sliding, uniformly compressing the piezoelectric material 105 in the cavity. This symmetrical design not only improves the efficiency of vibration energy capture, but also reduces the wear on one side of the sleeve by balancing the forces on both sides, thus extending the service life of the energy conversion unit 300.

[0048] Please see Figure 2 In one embodiment, the energy conversion unit 300 within the second connecting device 20 further includes a second conversion module 320. The second conversion module 320 can further improve the conversion rate of exhaust pipe vibration energy.

[0049] Specifically, the second conversion module 320 includes a housing 321 and an electromagnetic component 322. The housing 321 is sleeved on the connecting rod 106 and is fixedly connected to the connecting plate 102. The electromagnetic component 322 is disposed inside the housing 321 and is electrically connected to the energy harvesting unit.

[0050] Furthermore, the electromagnetic component 322 includes a magnetic rotor 3220 and a coil 3221. The magnetic rotor 3220 is located inside the housing 321 and rotatably connected to the connecting rod 106. The coil 3221 is disposed around the magnetic rotor 3220 and fixedly connected to the inner wall of the housing 321. Therefore, when the magnetic rotor 3220 rotates, the coil 3221 cuts magnetic field lines to generate current. The second conversion module 320 differs from the first conversion module 310. The second conversion module 320 converts the vibration of the exhaust pipe into the rotation of the magnetic rotor 3220, allowing the coil 3221 to cut magnetic field lines and generate current. Through the second conversion module 320, a conversion method based on exhaust pipe vibration energy is further provided, which, combined with the first conversion module 310, can greatly improve the conversion efficiency of exhaust pipe vibration energy.

[0051] Specifically, the first conversion module 310 generates electricity by compressing the piezoelectric material 105 through the linear displacement generated by the relative sliding of the first sleeve 103 and the second sleeve 104, which is more suitable for the linear vibration of the exhaust pipe. The second conversion module 320 generates electricity by cutting the path of magnetic field lines through the coil 3221, which is more suitable for the oscillating or rotational vibration of the exhaust pipe. The first conversion module 310 and the second conversion module 320 are complementary in principle, which can capture the multi-directional and multi-form vibration energy generated by the exhaust pipe during ship operation, avoid energy loss under a single principle, and significantly improve the overall energy recovery rate.

[0052] Meanwhile, the second conversion module 320, as a new energy channel, works in parallel with the first conversion module 310. The same vibration energy can simultaneously drive the piezoelectric material 105 to compress and the magnetic rotor 3220 to rotate, achieving the superposition effect of two electrical energy outputs under one vibration energy, directly improving the conversion efficiency from the perspective of energy utilization.

[0053] It is important to note that the second conversion module 320 is integrated into the existing hoisting system in a non-rigid interference manner through a structural design in which "the housing 321 is sleeved on the connecting rod 106" and "the magnet rotor 3220 is rotatably connected to the connecting rod 106". This design does not change the hoisting load-bearing capacity of the first connecting unit 100, nor does it affect the piezoelectric conversion function of the first conversion module 310. The overall structure enhances energy recovery while maintaining stable hoisting support for the exhaust pipe, achieving a balance between functional enhancement and core performance assurance.

[0054] Furthermore, to increase the rotational speed of the magnet rotor 3220, an eccentric flywheel 3222 can be provided on the magnet rotor 3220. This flywheel can increase the kinetic energy of the magnet rotor 3220 during rotation, thereby further improving the mechanical energy conversion efficiency. Specifically, the eccentric flywheel 3222 on the magnet rotor 3220 utilizes the characteristics of eccentric mass to convert intermittent, low-amplitude vibration energy into continuous high-speed kinetic energy of the rotor during vibration transmission. The increased speed directly enhances the strength of the coil 3221 cutting magnetic field lines, thereby increasing the power generation per unit time. At the same time, the inertia of the flywheel 3222 can buffer the instability of vibration, making the rotor rotate more smoothly and the output current more stable.

[0055] For low-amplitude, high-frequency vibrations commonly encountered in ship operation, the eccentric flywheel 3222 can amplify the rotor rotation effect through inertia, avoiding the problem that the electromagnetic conversion cannot be driven due to weak vibration energy, thus broadening the applicable vibration range of the second conversion module 320.

[0056] Furthermore, a sealing element 3223 is provided at the connection between the housing 321 and the connecting rod 106 for sealing. The sealing element 3223 can effectively improve the sealing effect of the housing 321 and extend the service life of the electromagnetic component 322. Specifically, the sealing element 3223 at the connection between the housing 321 and the connecting rod 106 can effectively prevent water vapor, oil, dust and other impurities in the ship's cabin from entering the interior of the housing 321, avoiding magnetic performance attenuation, short circuit of the coil 3221 or mechanical jamming caused by contamination of the electromagnetic component 322, and ensuring long-term stable operation of the electromagnetic conversion.
