Description

Technical Field

[0001] This invention relates to the field of marine air conditioning technology, specifically to a low-vibration integrated marine inverter air conditioner. Background Technology

[0002] Marine inverter air conditioners are variable frequency controlled air conditioning devices specifically designed for the unique environment of ships. Their core feature is the use of inverter technology to adjust compressor speed, achieving dynamic adaptation of cooling / heating capacity while meeting the temperature and humidity control requirements of ships under different operating conditions such as navigation and berthing. Integrated marine inverter air conditioners represent a high-end, all-in-one form of marine inverter air conditioning. Their core feature is the integration of multiple key components into a single sealed enclosure, allowing for direct hoisting or floor installation without complex on-site assembly. This makes them suitable for scenarios with limited space and inconvenient installation and maintenance on ships.

[0003] In existing technologies, the core modules of integrated marine inverter air conditioners are usually installed directly on the bottom surface inside the casing. When the core modules are working, the mechanical vibrations generated are transmitted to the hull through the bottom of the casing, which can easily resonate with the hull structure and cause multiple problems. Therefore, when installing integrated marine inverter air conditioners, vibration damping plates are installed between the bottom of the casing and the hull. However, ships sail at sea for long periods of time, causing the vibration damping plates to be exposed to the high salt spray environment of the ocean for a long time. This makes them prone to aging and hardening, which greatly reduces the vibration damping effect. The vibration damping plates may even crack and fall off, causing the air conditioner to tilt and become unstable, reducing safety.

[0004] Therefore, we propose a low-vibration integrated marine variable frequency air conditioner to address the problems mentioned in the background section. Summary of the Invention

[0005] The purpose of this invention is to provide a low-vibration integrated marine inverter air conditioner to solve the problem mentioned in the background art. When installing an integrated marine inverter air conditioner, a vibration damping plate is installed between the bottom of the casing and the hull. However, the vibration damping plate is exposed to the high salt spray environment of the ocean for a long time, which makes it easy to age and harden, greatly reducing the vibration damping effect. The vibration damping plate may even crack and fall off, causing the air conditioner to tilt and become unstable, reducing safety.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a low-vibration integrated marine variable frequency air conditioner, comprising a variable frequency air conditioner body, wherein a bottom vibration damping component is provided inside the variable frequency air conditioner body, and a modular vibration damping component and a connecting component are provided on the top of the bottom vibration damping component; the modular vibration damping component is used for modular area vibration damping, and the bottom vibration damping component is used for further overall vibration damping.

[0014] Preferably, one end of each of the four sets of clamping rods extends movably through the outer surfaces of both sides of the two U-shaped plates. The multiple return springs are arranged in groups of multiple return springs distributed longitudinally, and the multiple support rods are arranged in groups of multiple support rods distributed longitudinally. One end of each of the four sets of return springs is fixedly connected to the inner wall of the two U-shaped plates, and the other end of each of the four sets of return springs is fixedly connected to the inner wall of the four limiting plates. One end of each of the four sets of support rods is fixedly installed at the top of the outer surfaces of both sides of the two partition plates, and the other end of each of the four sets of support rods is fixedly installed on the inner wall of the two U-shaped plates. The tops of the four fixing frames are fixedly installed at the bottom of the four limiting plates near the reinforcing plates. The four reinforcing plates are movably embedded inside the two U-shaped plates.

[0015] Preferably, the bottom vibration damping assembly includes a fixed plate, a plurality of vibration damping seats are provided on the bottom of the fixed plate, and bottom vibration damping pads are provided on the four sides of the bottom of the fixed plate. The bottoms of the plurality of vibration damping seats are bolted to the bottom surface inside the inverter air conditioner body, and the bottoms of the plurality of bottom vibration damping pads are in contact with the bottom surface inside the inverter air conditioner body.

The two mounting brackets are bolted to the top of the fixed plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the outer surface of the rubber damping pad is coated with a fluorosilane superhydrophobic coating, and the outer surface of the bottom damping pad is coated with a gradient ceramic coating, making it suitable for high salt spray environments. Both the bottom damping component and the modular damping component are installed inside the inverter air conditioner body, directly absorbing vibration energy within the enclosure, reducing the efficiency of vibration transmission to the bottom of the enclosure, and reducing the impact of vibration on the hull from the source, achieving low-vibration operation. Simultaneously, the enclosure protects the bottom damping component and the modular damping component from direct exposure to high salt spray environments and long-term contact with high salt spray air, reducing the risk of aging and corrosion, which helps to improve the service life of each damping structure and enhance the stability of the air conditioner.

[0017] 2. When this invention is used, as vibrational energy propagates into the acoustic black hole region of the inner thin plate, the vibrational energy is concentrated in the central region of the acoustic black hole. The aerogel felt helps to weaken the residual vibrations that are not concentrated by the wedge-shaped grooves. The high-density copper oscillator and the damping ring work together to form a local resonance unit, further dissipating the vibrational energy. The damping ring prevents the vibration of the high-density copper oscillator itself from being transmitted outward. The support plate has high structural strength and rigidity. The damping material absorbs the residual vibrational energy. Through vibration concentration, multi-layer structure synergistic dissipation of vibration, and structural stability, effective vibration reduction is achieved. The butterfly-shaped elastic sheet in the vibration damping groove is composed of symmetrical C-shaped elastic sheets, which can balance the forces in different directions. The vortex curling greatly increases the effective deformation length of the C-shaped elastic sheet, thereby buffering a wider range of vibrational impacts. The vortex curling can complete the deep dissipation of vibrational energy. The modular vibration damping components are independent and separate parts, each supporting a different equipment module. The vibration of each module is limited to its own range, avoiding the superposition of vibrations from multiple modules to form "composite vibration". Together with the bottom vibration damping components, the overall vibration damping and noise reduction of multiple module vibration damping components is further achieved.

[0018] 3. In use, the electric actuator is activated, pushing the moving plate and reinforcing plate downwards, causing the guide post to insert into the guide groove and the insertion rod to pass through the insertion hole. When the electric actuator automatically closes, the reinforcing plate moves to the top of the connecting plate, the locking rod aligns with the insertion rod, and the conductive post enters the conductive sleeve and is energized. Then, the electromagnet generates the same magnetism as the square magnet, forcing the fixed frame to push the reinforcing plate to move, forcing the locking rod to insert into the locking groove, thereby connecting the two separate connecting plates together. This connects two adjacent modular vibration damping components together, and further connects multiple independent modular vibration damping components into a whole, enhancing impact resistance and improving the stability of the air conditioner. Through the connecting components, modular independent areas can be achieved, ensuring low-vibration operation in daily life, while also being connected as a whole to handle special situations.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figures 1-11As shown, the present invention provides a technical solution: a low-vibration integrated marine inverter air conditioner, including an inverter air conditioner body 1. A bottom vibration damping component 3 is disposed inside the inverter air conditioner body 1. A modular vibration damping component 4 and a connecting component 5 are disposed on the top of the bottom vibration damping component 3. The modular vibration damping component 4 is used for modular area vibration damping, and the bottom vibration damping component 3 is used for further overall vibration damping. The modular vibration damping component 4 includes a modular plate 401. An mounting plate 406 is fixedly installed on the top surface inside the modular plate 401, and an inner thin plate 4 is fixedly installed on the bottom of the mounting plate 406. 07. The top of the inner thin plate 407 is provided with multiple wedge-shaped grooves 408. The bottom of the inner thin plate 407 is fixedly connected to an aerogel felt 409. The bottom of the aerogel felt 409 is provided with a sleeve plate 410. Multiple damping rings 411 are fixedly connected inside the sleeve plate 410. High-density copper oscillators 412 are fixedly connected to the inner walls of the multiple damping rings 411. The bottom of the high-density copper oscillators 412 is provided with a support plate 413. Multiple honeycomb grooves 414 are provided inside the support plate 413. The interior of the multiple honeycomb grooves 414 is filled with damping material 415. The thickness of the wedge-shaped grooves 408 gradually decreases according to a power law. The wedge-shaped grooves 408 are distributed in a linear array, utilizing the "acoustic black hole effect" to concentrate vibration waves and reduce downward transmission. The aerogel felt 409 is a porous and lightweight material used to weaken residual vibrations not concentrated by the wedge-shaped grooves 408. The high-density copper oscillator 412 consumes the energy concentrated by the wedge-shaped grooves 408 again through resonance. The damping ring 411 is used to prevent the vibration of the high-density copper oscillator 412 itself from being transmitted outward. The damping material 415 filled inside the honeycomb groove 414 absorbs the residual vibration energy transmitted from the upper layer again, further attenuating the vibration. The inner thin plate 407, aerogel felt 409, high-density copper oscillator 412 and damping material 415 work together to achieve initial effective vibration reduction. The damping ring 411 is made of polyurethane elastomer material, and the damping material 415 is made of butyl rubber foam material. Multiple spring damping seats 402 are fixedly installed on the bottom of the modular plate 401. Rubber vibration damping pads 403 are provided at the bottom edge of the modular plate 401. Each of the multiple rubber vibration damping pads 403 has a vibration damping groove 404 inside. Each of the multiple vibration damping grooves 404 has a butterfly elastic sheet 405 fixedly connected inside. The butterfly elastic sheet 405 is composed of two C-shaped elastic sheets, and both ends of the C-shaped elastic sheets are spirally curled. The outer surface of the rubber vibration damping pads 403 is coated with a fluorosilane superhydrophobic coating. The spring damping seats 402 cooperate with the rubber vibration damping pads 403 to achieve secondary vibration damping.The bottom vibration damping assembly 3 includes a fixed plate 301, with multiple vibration damping seats 302 at the bottom of the fixed plate 301. Bottom vibration damping pads 303 are provided at the four edges of the bottom of the fixed plate 301. The bottoms of the multiple vibration damping seats 302 are all bolted to the bottom surface inside the inverter air conditioner body 1. The bottoms of the multiple bottom vibration damping pads 303 are in contact with the bottom surface inside the inverter air conditioner body 1. The outer surface of the bottom vibration damping pads 303 is coated with a gradient ceramic coating. A controller 2 is fixedly installed on the outer surface of the inverter air conditioner body 1. The bottoms of the multiple spring damping seats 402 are all bolted to the top of the fixed plate 301. The bottoms of the multiple rubber vibration damping pads 403 are all in contact with the top of the fixed plate 301. Two mounting brackets 510 are bolted to the top of the fixed plate 301.

[0023] In this embodiment, during use, the inverter air conditioner body 1 includes a cooling / heating module, a ventilation and air purification module, an inverter control and monitoring module, and an energy-saving auxiliary module. Each working device module is installed on top of the three module vibration damping components 4. The vibration generated during the operation of each working device module is transmitted downward through the mounting plate 406. An array of wedge-shaped grooves 408 are provided on the inner thin plate 407, forming an acoustic black hole array. The internal structure of the wedge-shaped grooves 408 gradually shrinks according to a power law. When the bending waves (the main propagation form of vibration) generated by the working device modules inside the air conditioner propagate to the acoustic black hole region of the inner thin plate 407, the phase velocity of the bending waves gradually decreases, preventing the vibration energy from continuing to propagate outward. Instead, the energy is concentrated at the tip or center of the acoustic black hole. By allowing vibration waves of different frequencies to enter the corresponding black hole regions, the concentrated diffusion of vibration energy is avoided. Some of the unconcentrated vibrational energy is transferred to the aerogel felt 409. The aerogel felt 409, being a porous and lightweight material, helps to weaken residual vibrations not concentrated by the wedge-shaped groove 408. Furthermore, the hydrophobicity of the aerogel felt 409 isolates it from salt corrosion, protecting the upper and lower structures. The high-density copper oscillator 412 has its own inherent vibrational frequency. Together with the external damping ring 411, it forms a localized resonant unit. When the vibrational frequency is close to the inherent frequency of the high-density copper oscillator 412, it will resonate, further dissipating vibrational energy. The high density of copper enhances the concentration effect at the tip of the wedge-shaped groove 408, making it easier for vibrational energy to concentrate in the tip area. The damping ring 411 dissipates the vibrational energy of the high-density copper oscillator 412, preventing its own vibration from being transmitted outwards. The support plate 413 has high structural strength and rigidity, facilitating stable equipment installation. The damping material 415 filled inside the honeycomb groove 414 absorbs residual vibration energy transmitted from the upper layer, further attenuating vibration. The inner thin plate 407, aerogel felt 409, high-density copper oscillator 412, and damping material 415 work together to achieve effective vibration reduction through vibration concentration, multi-layer structure synergistic vibration dissipation, and structural stability. The damping ring 411 is made of polyurethane elastomer material, and the damping material 415 is made of butyl rubber foam material, both suitable for high-salt-fog marine environments. Meanwhile, the bottom spring damping seat 402, in conjunction with the rubber vibration damping pad 403, enhances the vibration reduction effect, achieving low-vibration operation. The butterfly-shaped elastic sheet 405 in the vibration damping groove 404 consists of two C-shaped elastic sheets, with both ends of the C-shaped elastic sheet arranged in a spiral curl, such as... Figure 6As shown, the symmetrical C-shaped structure can simultaneously cope with vertical and horizontal bidirectional vibrations, balance the forces in different directions, and avoid excessive deformation on one side. The vortex curling greatly increases the effective deformation length of the C-shaped elastic sheet, which can generate greater elastic deformation within a smaller compression range, thereby buffering a wider range of vibration impacts. Each coil of the vortex curling is equivalent to an independent elastic unit. When the vibration is transmitted to the elastic sheet, the curled part will deform coil by coil. Through the internal friction of the metal sheet and the contact friction between the coils, the vibration energy is deeply dissipated.

[0024] Furthermore, the outer surface of the rubber vibration damping pad 403 is coated with a fluorosilane superhydrophobic coating, which has strong salt spray resistance and does not affect the elasticity of the rubber. The outer surface of the bottom vibration damping pad 303 is coated with a gradient ceramic coating, which can inhibit the breakage of rubber molecular chains caused by acidic salt spray, prevent hardening and cracking, and is resistant to high temperature and mechanical wear. The bottom vibration damping component 3 and the module vibration damping component 4 are both installed inside the inverter air conditioner body 1, directly absorbing vibration energy inside the enclosure, reducing the efficiency of vibration transmission to the bottom of the enclosure, reducing the impact of vibration on the hull from the source, and damping vibration between the core equipment module and the external enclosure to achieve low vibration operation. At the same time, the enclosure protects the bottom vibration damping component 3 and the module vibration damping component 4 from direct exposure to the high salt spray environment and long-term contact with high salt spray air, reducing the risk of aging and corrosion, which is conducive to improving the service life of each vibration damping structure and improving the stability of the air conditioner. This solution addresses the problem that when installing integrated marine inverter air conditioners, vibration damping plates are installed between the bottom of the unit and the hull. However, these plates are exposed to the high salt spray environment of the ocean for extended periods, which can cause them to age and harden, significantly reducing their damping effect. In some cases, the plates may even crack and fall off, leading to the air conditioner tilting and becoming unstable, thus reducing its safety.

[0025] Furthermore, multiple module vibration damping components 4 are provided, and the corresponding number of module vibration damping components 4 and connecting components 5 can be selected for installation as needed. The module vibration damping components 4 are independent and separate parts, each supporting different equipment modules. The vibration of each module is limited to its own range, avoiding the superposition of vibrations from multiple modules to form "composite vibration". Together with the bottom vibration damping component 3, the multiple module vibration damping components 4 are further used to achieve overall vibration reduction and noise reduction.

A fixing frame 521 is provided on one outer surface of each of the four electromagnets 520. A square magnet 522 is fixedly connected inside each of the four fixing frames 521. A reinforcing plate 523 is fixedly installed on one side of the outer surface of each of the four fixed frames 521. Multiple locking rods 524 are fixedly installed on one side of the outer surface of each of the four reinforcing plates 523. A limiting plate 525 is fixedly installed on the top of each of the four reinforcing plates 523. Multiple support rods 526 are movably embedded inside each of the four limiting plates 525. A return spring 527 is movably sleeved on the outer surface of each of the multiple support rods 526. Conductive posts 503 are fixedly installed on the bottom surface inside each of the two guide grooves 502. Insulating grooves 508 are opened at the bottom ends of each of the two guide posts 505. Conductive sleeves 509 are fixedly installed inside each of the two insulating grooves 508. Two telescopic rods 512 are fixedly installed on the top surface inside each of the two mounting brackets 510. The bottom ends of the four telescopic rods 512 are fixedly installed on the top of the two movable plates 513 respectively. The bottoms of the six connecting brackets 515 are fixedly installed on the top of the two reinforcing plates 504 respectively. There are three modular vibration damping components 4. The outer surface of one side of the two connecting plates 501 is fixedly installed on the outer surface of one side of the two modular plates 401 respectively. The outer surface of one side of the other two connecting plates 501 is fixedly installed on the outer surfaces of both sides of the other modular plate 401 respectively. The multiple clamping rods 524 are evenly divided into four groups.One end of each of the four sets of locking rods 524 extends movably through the outer surfaces of both sides of the two U-shaped plates 516. Multiple return springs 527 are distributed longitudinally as a group, and multiple support rods 526 are distributed longitudinally as a group. One end of each of the four sets of return springs 527 is fixedly connected to the inner wall of the two U-shaped plates 516, and the other end of each of the four sets of return springs 527 is fixedly connected to the inner wall of the four limiting plates 525.

The tops of the four fixing frames 521 are fixedly installed at the bottom of the four limiting plates 525 near the reinforcing plate 523, and the four reinforcing plates 523 are movably embedded inside the two U-shaped plates 516.

[0027] In this embodiment, during use, the electric actuator 511 is activated, pushing the moving plate 513 downward. Through the cooperation of the damper 514 and the connecting frame 515, the reinforcing plate 504 is pushed downward, causing multiple guide posts 505 to be inserted into the corresponding guide grooves 502. Then, the insertion rod 506 passes through the corresponding insertion hole 507. When the electric actuator 511 automatically closes, the reinforcing plate 504 moves to the top of the connecting plate 501, the locking rod 524 aligns with the insertion rod 506, and the conductive post 503 enters the conductive sleeve 509 and is energized. At this time, the electromagnet 520 is energized and generates the same magnetism as the square magnet 522. Under the push of the repulsive force, the fixed frame 521 is forced to push the reinforcing plate 523 to move, causing the limiting plate 525 to slide on the outer surface of the support rod 526 and compressing the return spring 527 to retract, thereby forcing the locking rod 524 to move and insert into the corresponding slot 517. The cooperation of clamp 524 and insert 506 allows the reinforcing plate 504 to connect the two separate connecting plates 501 together, thereby connecting two adjacent modular vibration damping components 4 together. This, in turn, connects multiple independent modular vibration damping components 4 into a whole. When the ship encounters extreme sea conditions such as typhoons or giant waves, and the hull sways significantly, this unified connection enhances the structural rigidity and impact resistance, improving the stability of the air conditioner and preventing displacement or instability of separately installed core modules due to uneven stress. The connecting component 5 allows for modular independent areas to ensure low-vibration operation in daily life, while also enabling connection into a whole to handle special circumstances.

[0028] The overall effect and working principle of the mechanism are as follows: Each core equipment module inside the variable frequency air conditioner body 1 is installed on top of three module vibration damping components 4. An array of wedge-shaped grooves 408 are arranged on the inner thin plate 407, forming an acoustic black hole array. The internal structure of the wedge-shaped grooves 408 gradually decreases according to a power law. When vibration energy propagates into the acoustic black hole region of the inner thin plate 407, the phase velocity of the bending wave gradually decreases, causing the vibration energy to concentrate at the tip or center of the acoustic black hole. Some of the unconcentrated vibration energy is transferred to the aerogel felt 409, assisting in weakening the residual vibration not concentrated by the wedge-shaped grooves 408. The high-density copper oscillator 412, in conjunction with the external damping ring 411, forms a local resonance unit, further consuming vibration energy. The damping ring 411 prevents the vibration of the high-density copper oscillator 412 itself from being transmitted outwards. The support plate 413 has high structural strength and rigidity, facilitating stable equipment installation. The damping material 415 absorbs the residual vibration energy transmitted from the upper layer, further attenuating the vibration. Effective vibration reduction is achieved through vibration concentration, multi-layered structure synergistic vibration dissipation, and structural stability. Simultaneously, the bottom spring damping seat 402, in conjunction with the rubber damping pad 403, enhances the vibration reduction effect, achieving low-vibration operation. The butterfly-shaped elastic sheet 405 in the damping groove 404 consists of two C-shaped elastic sheets, with both ends of the C-shaped elastic sheet arranged in a spiral curl. The symmetrical C-shaped structure can balance forces in different directions, and the spiral curl significantly increases the effective deformation length of the C-shaped elastic sheet, buffering a wider range of vibration impacts. When vibration is transmitted to the elastic sheet, the curled part deforms sequentially, completing the deep dissipation of vibration energy. The outer surface of the rubber damping pad 403 is coated with a fluorosilane superhydrophobic coating, exhibiting strong salt spray resistance. The outer surface of the bottom damping pad 303 is coated with a gradient ceramic coating to prevent hardening and cracking. Both the bottom vibration damping component 3 and the module vibration damping component 4 are installed inside the inverter air conditioner body 1, directly absorbing vibration energy inside the housing, reducing the efficiency of vibration transmission to the bottom of the housing, reducing the impact of vibration on the hull from the source, and damping vibration between the core equipment module and the external housing to achieve low vibration operation. At the same time, the housing protects the bottom vibration damping component 3 and the module vibration damping component 4 from direct exposure to the high salt spray environment and long-term contact with the high salt spray air, reducing the risk of aging and corrosion.The electric actuator 511 is activated, pushing the moving plate 513 downward. Through the cooperation of the damper 514 and the connecting frame 515, the reinforcing plate 504 is pushed downward, causing multiple guide posts 505 to insert downward into the corresponding guide slots 502. Then, the insertion rod 506 passes through the corresponding insertion hole 507. When the electric actuator 511 automatically closes, the reinforcing plate 504 moves to the top of the connecting plate 501, and the locking rod 524 aligns with the insertion rod 506. The conductive post 503 enters the conductive sleeve 509 and is energized. At this time, the electromagnet 520 is energized and generates the same magnetism as the square magnet 522. Under the push of the repulsive force, the fixed frame 521 is forced to push the reinforcing plate 523 to move, causing the limiting plate 525 to slide on the outer surface of the support rod 526 and compress the return spring 527 to retract, thereby forcing the locking rod 524 to move and insert into the corresponding slot 517. The cooperation between the clamp 524 and the insertion rod 506 allows the reinforcing plate 504 to connect the two separate connecting plates 501 together, thereby connecting two adjacent modular vibration damping components 4 together, and ultimately connecting multiple independent modular vibration damping components 4 into a whole. Through the connecting component 5, modular independent areas can be achieved, ensuring low-vibration operation in daily life, while also being connected as a whole to handle special situations.
