[0036] The present utility model discloses a vibration damping device for a pipeline system to reduce the vibration generated by the pipeline system due to the vibration of the compressor, thereby ensuring the safety performance of the pipeline system of the compressor.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0038] Hereinafter, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0039] A compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas and is the heart of a refrigeration system.

[0040] Taking the compressor in an air conditioner as an example, after the compressor is assembled, it is connected to the pipeline system. However, during the operation of the compressor, vibrations will be generated, and the vibrations of the compressor will be transmitted to the pipeline system, affecting the connection of the pipeline system. It should be noted that the compressor involved in this application includes, but is not limited to, the compressor on an air conditioner, and can also be a compressor with other structures.

[0041] Due to the very wide operating frequency band of the compressor of the air conditioner, it is difficult to avoid the occurrence of resonance in the design of the pipeline system of the compressor, resulting in relatively large noise and vibrations in the air conditioner, and even causing problems such as the fracture of the pipeline system and refrigerant leakage.

[0042] Based on this, a vibration damping device for a pipeline system is disclosed in this application. By setting a vibration damping device on the pipeline to be damped, the vibration frequency or vibration amplitude of the pipeline system is reduced, thereby avoiding resonance with the compressor or reducing the vibration amplitude generated by resonance.

[0043] Combined Figure 1 and Figure 2 As shown, the vibration damping device in this application includes: a base 1, a connecting arm 2, and a damper 3.

[0044] Among them, the base 1 is a basic structure, and the base 1 can be a cylindrical structure or a polygonal structure. The connecting arm 2 is hinged to the base 1, and there are multiple connecting arms 2. Exemplarily, the base 1 is a polygonal columnar structure, and each side of the base 1 is connected to a connecting arm 2.

[0045] The connecting arm 2 can undergo elastic deformation, that is, the stiffness of the connecting arm 2 is adjustable. The first end of the connecting arm 2 is hinged to the base 1, and the second end is connected to the pipeline to be vibration-damped. The second ends of at least two connecting arms 2 are connected to different pipelines to be vibration-damped. The way that the first end of the connecting arm 2 is hinged to the base 1 includes but is not limited to being hinged through a ball head 211, and the ball head 211 is rotatably installed in the base 1. In some embodiments, the pipeline to be vibration-damped can be an intake pipe and an exhaust pipe connected to a compressor. The number of the connecting arms 2 can be set according to different needs, and all are within the protection scope.

[0046] The connecting arm 2 can undergo elastic deformation, so as to absorb vibration energy.

[0047] The connecting arm 2 is hinged to the base 1, and the angle of the connecting arm 2 relative to the central axis (the axis of the installation groove 13) of the base 1 can be changed. Exemplarily, when the extending direction of the connecting arm 2 is perpendicular to the pipeline to be vibration-damped and the connecting arm 2 is perpendicular to the central axis of the base 1, the elastic deformation of the connecting arm 2 can fully act on the pipeline to be vibration-damped. When the included angle between the connecting arm 2 and the base 1 is less than 90°, only a part (the component along the direction perpendicular to the central axis) of the elastic deformation of the connecting arm 2 acts on the pipeline to be vibration-damped. Therefore, by hinging the connecting arm 2 to the base 1 and changing the rotation angle of the connecting arm 2 relative to the base 1, the elastic deformation of the connecting arm 2 acting on the pipeline to be vibration-damped can be changed, so as to change the vibration damping effect of the connecting arm 2 acting on the pipeline to be vibration-damped and reduce the vibration amplitude of the pipeline to be vibration-damped.

[0048] It should be noted that in combination Figure 2 As shown, the initial state of the connecting arm 2 is in the same plane as the base. It can be understood that the plane where the connecting arm 2 is located coincides with the plane of the base 1, that is, the included angle is zero. After the connecting arm 2 rotates upward or downward relative to the central axis of the base 1, an included angle will be generated between the plane where the connecting arm 2 is located and the plane of the base 1.

[0049] The relationship between the connecting arm 2 and the base 1 is described in the above two directions, but the relationship between the connecting arm 2 and the base 1 is the same.

[0050] In addition, the connecting arm 2 is hinged to the base 1 and the length of the connecting arm 2 is adjustable, which can adapt to different space installation needs and make the adaptability of the vibration damping device in this application higher.

[0051] The damper 3 is arranged on the base 1 and is used to provide a damping force for the vibration of the vibration damping device, so as to further reduce the vibration amplitude of the pipeline to be vibration-damped. Exemplarily, the damper 3 is arranged at the central axis position of the base 1 to ensure that the damping effect of each part of the vibration damping device is the same. The number of the dampers 3 can be set according to different needs, and all are within the protection scope.

[0052] The vibration damping device disclosed in this application uses the connecting arm 2 to connect the pipelines with large vibrations in the pipeline system of the compressor, so that these pipelines to be measured are connected as a whole, and uses the elastic deformation of the connecting arm 2 to buffer the vibration of the pipelines to be measured, absorb the vibration energy of the pipelines to be measured, reduce the vibration intensity of the pipelines to be measured, and uses the damper 3 to provide resistance to the vibration of the pipelines to be measured, further reducing the vibration amplitude of the pipelines to be measured, thereby effectively achieving the purpose of vibration damping of the pipelines to be measured, alleviating the resonance between the pipelines to be measured and the compressor, and reducing the vibration amplitude during the resonance between the pipelines to be measured and the compressor.

[0053] As Figure 3 shown in the embodiment, the base 1 includes a base body 11, a mounting hole 12, a mounting groove 13 and a limiting ring 14.

[0054] Among them, the base body 11 is a polygonal cylindrical structure, a through mounting hole 12 is provided at the central position of the base body 11, and the damper 3 is arranged in the mounting hole 12. The connection methods between the damper 3 and the mounting hole 12 include but are not limited to fitting connection or clamping connection, and any connection method that can realize the detachable connection between the damper 3 and the mounting hole 12 is within the protection scope. It should be noted that after the damper 3 is installed in this application, a damping force opposite to the vibration direction of the base body 11 can be generated.

[0055] In some embodiments, the damper 3 is an electromagnetic particle damper. Specifically, the structure of the electromagnetic particle damper includes a non-ferromagnetic cavity with openings at both ends. One end of the electromagnetic particle damper is installed with a ferromagnetic end cap, and the other end is installed with a non-ferromagnetic end cap. The ferromagnetic end cap and the non-ferromagnetic end cap seal the non-ferromagnetic cavity, and ferromagnetic particles are contained in the cavity. A coil is wound around the outside of the non-ferromagnetic cavity. When energized, the electromagnetic field generated by the solenoid will magnetize both the ferromagnetic particles and the ferromagnetic end cap. After the ferromagnetic particles are magnetized, they interact with the magnetic field to increase the relative movement between the particles, thereby achieving the purpose of increasing energy consumption.

[0056] By changing the current magnitude of the electromagnetic particle damper, the magnitude of the damping force of the electromagnetic particle damper can be changed. The range value of the current of the electromagnetic particle damper can be set according to different needs, and all are within the protection scope.

[0057] In some embodiments, the damper 3 can also be a viscous damper, and is not limited to the above disclosed types of dampers.

[0058] The side wall of the base body 11 is provided with a mounting groove 13, and the mounting groove 13 is a ball socket structure. The ball head 211 of the connecting arm 2 is rotatably mounted in the mounting groove 13. In order to limit the ball head 211 in the mounting groove 13, a limiting ring 14 is sleeved outside the ball head 211. The limiting ring 14 is an annular structure, and the inner diameter of the limiting ring 14 is smaller than the diameter of the ball head 211. The limiting ring 14 is detachably connected to the base body 11, and after the limiting ring 14 is connected to the base body 11, it can prevent the ball head 211 from detaching from the mounting groove 13.

[0059] Exemplarily, the base body 11 is provided with threads at the mounting groove 13, and the limiting ring 14 is threadedly connected to the base body 11. Those skilled in the art can understand that the base body 11 and the limiting ring 14 can also be connected by snap connection.

[0060] Combined with Figures 4 to 7 the connecting arm 2 shown in it, the connecting arm 2 in the present application includes: a rotating assembly 21, a sleeve 22, a connecting buckle 23, an adjusting rod 24 and a spring 25. Among them, the rotating assembly 21 includes a ball head 211 and a connecting rod 212.

[0061] One end of the sleeve 22 is detachably connected to the connecting buckle 23, and the other end of the sleeve 22 is telescopically connected to the rotating assembly 21. Specifically, the other end of the sleeve 22 is telescopically connected to the connecting rod 212, so that the distance between the connecting rod 212 and the connecting buckle 23 is adjustable, that is, the length of the connecting arm 2 can be changed.

[0062] As Figure 6 shown, the sleeve 22 includes a first section 221, a second section 222 and a limiting section 223. Among them, the first section 221 is a hollow structure, the second section 222 is a hollow structure, and the first section 221 and the second section 222 are integrally formed into a hollow structure. The limiting section 223 is a frustum on the inner wall of the sleeve 22, and the frustum has a through hole penetrating along the axis direction of the sleeve 22. It can be understood that the limiting section 223 can be located in the first section 221 or the second section 222.

[0063] Combined with Figure 7 shown, one end of the connecting buckle 23 is a hollow structure and has internal threads. The internal threads of the connecting buckle 23 are in threaded connection with the external threads of the first section 221 to realize the detachable connection between the connecting buckle 23 and the sleeve 22. Those skilled in the art can understand that the connection method between the connecting buckle 23 and the sleeve 22 includes but is not limited to threaded connection and can also be snap connection. After the connecting buckle 23 is connected to the first section 221, it can close one end of the first section 221 away from the second section 222.

[0064] Combined with Figure 5 and Figure 7 shown, the adjusting rod 24 includes: a limiting head 241, a smooth shaft section 242 and a threaded section 243.

[0065] Wherein, one end of the optical axis section 242 is fixedly connected to the limit head 241, and the other end is fixedly connected to the threaded section 243. In some embodiments, the limit head 241, the optical axis section 242, and the threaded section 243 are integrally formed structures. Exemplarily, the optical axis section 242 includes, but is not limited to, a cylinder. The threaded section 243 can be understood as a section of the cylinder with threads provided thereon. The diameter of the limit head 241 is greater than the diameter of the optical axis section 242, and the diameter of the limit head 241 is greater than the diameter of the through hole of the limit section 223, so as to achieve that the limit head 241 abuts against the edge of the through hole of the limit section 223 and cannot pass through the through hole. Those skilled in the art can connect that the limit head 241 includes, but is not limited to, a cylinder, and any structure that can achieve abutting against the edge of the through hole of the limit section 223 is within the protection scope.

[0066] See Figure 7 As shown, the threaded section 243 of the adjusting rod 24 is threadedly connected to the connecting rod 212 of the rotating assembly 21. The limit head 241 is arranged in the first section 221 of the sleeve 22 and abuts against the through hole of the limit section 223. And the limiting direction of the limit section 223 is to limit in the direction towards the rotating assembly 21, but it can move in the opposite direction, that is, the adjusting rod 24 can drive the rotating assembly 21 to move towards the connecting buckle 23.

[0067] The spring 25 is located in the second section 222 of the sleeve 22, and one end abuts against the connecting rod 212, and the other end abuts against the side of the limit section 223 facing the second section 222. Under the action of the spring 25, it can provide resistance to the process of the rotating assembly 21 moving towards the connecting buckle 23 and provide a restoring force for the reset of the rotating assembly 21.

[0068] The above discloses a specific structure of the connecting arm 2. The length of the connecting arm 2 is adjustable, and different damping forces can be generated during the length change process of the connecting arm 2 to absorb the vibration energy of the pipeline to be vibration-damped. In addition, the angle of the connecting arm 2 relative to the base 1 is adjustable, so as to change the position of the vibration damping device relative to the pipeline to be vibration-damped, and further change the natural frequency of the pipeline to be vibration-damped connected with the vibration damping device, thereby solving the problem of resonance between the pipeline to be vibration-damped and the compressor.

[0069] Combined with the calculation formula of the natural frequency of the mechanical vibration system, it can be known that the natural frequency of the vibration system is related to the elastic coefficient (stiffness) and mass of the object. Therefore, the vibration damping device in this application changes the elastic coefficient of the connecting arm 2 and the elastic coefficient of the damper, thereby changing the natural frequency of the pipeline to be vibration-damped, so as to solve the resonance problem; the weight of the connecting arm 2 in this application can also be changed to change the fixed frequency of the pipeline to be vibration-damped connected with the vibration damping device; in addition, the angle and length of the connecting arm 2 are adjustable, and the vibration amplitude of the pipeline to be vibration-damped can be changed.

[0070] As described above, it can be seen that the vibration damping device in the present application can adjust the vibration characteristics of the pipeline system of the compressor by changing the length, the inclination angle relative to the base 1, the number, the weight of the connecting arm 2, and the elastic coefficient of the spring 25 and the elastic coefficient of the damper 3, so as to achieve the purpose of reducing vibration and noise.

[0071] Combined with Figure 8 As shown, the present application also discloses a method for adjusting parameters of a vibration damping device, including:

[0072] Preset the parameters of the vibration damping device.

[0073] It is preset that there are three connecting arms in the vibration damping device, and the three connecting arms are evenly arranged along the circumference of the base, and the connecting arms are arranged parallel to the plane where the base is located. The length of the connecting arm is the initial length, and this initial length can be set according to the installation space. It is preset that the elastic coefficient of the spring of the connecting arm is k1, and the damping coefficient of the damper is c1; the preset parameters are stored in the simulation system.

[0074] Start.

[0075] Start the compressor, obtain the acceleration information during the operation of the compressor, and store the obtained acceleration information in the simulation system. And there are first standard acceleration information, second standard acceleration information and third standard acceleration information pre-stored in the simulation system, and the first standard acceleration value a1 corresponding to the first standard acceleration information is greater than the second standard acceleration value a2 corresponding to the second standard acceleration information; the second standard acceleration value a2 is greater than the third standard acceleration value a3 corresponding to the third standard acceleration information.

[0076] Adjust the parameters of the vibration damping device.

[0077] When the acceleration value a0 corresponding to the obtained acceleration information is greater than the first standard acceleration value a1, reduce the stiffness of the connecting arm, that is, reduce the elastic coefficient of the spring of the connecting arm, until the acceleration value a0 corresponding to the obtained acceleration information is less than the first standard acceleration value a1.

[0078] When the acceleration value a0 corresponding to the obtained acceleration information is less than the first standard acceleration value a1 and greater than the second standard acceleration value a2, the connecting arm inclines relative to the plane where the base is located, and the inclination angle increases, and the length of the connecting arm increases (the rotating component 21 extends out relative to the sleeve 22), until the acceleration value corresponding to the continuously obtained acceleration information is less than the second standard acceleration value.

[0079] It should be noted that since there are multiple connecting arms, during the process of adjusting the inclination angle of the connecting arms relative to the plane where the base is located, all the connecting arms can be adjusted individually in sequence until the acceleration value a0 corresponding to the acquired acceleration information is less than the first standard acceleration value a1. By adopting this adjustment method, the inclination angles of the connecting arms may be different.

[0080] It is also possible to adopt synchronous adjustment of the connecting arms, and the angle adjusted each time is the same, until the acceleration value a0 corresponding to the acquired acceleration information is less than the first standard acceleration value a1. By adopting this adjustment method, the inclination angles of the connecting arms are the same.

[0081] When the acceleration value corresponding to the acquired acceleration information is less than the second standard acceleration value and greater than the third standard acceleration value, increase the magnitude of the damping force of the damper until the acceleration value corresponding to the acquired acceleration information is less than the third standard acceleration value.

[0082] Exemplarily, taking the electromagnetic particle damper as an example, it is necessary to increase the current passed through the electromagnetic particle damper.

[0083] When the acceleration value corresponding to the acquired acceleration information is less than the third standard acceleration value, output the number of connecting arms, the inclination angle of the connecting arms relative to the plane where the base is located, the length of the connecting arms, the elastic coefficient of the spring, and the damping coefficient of the damper.

[0084] The vibration damping device in the present application changes the natural frequency of the pipeline to be vibration-damped by changing the elastic coefficient of the connecting arms and the elastic coefficient of the damper, thereby solving the resonance problem; the weight of the connecting arms in the present application can also be changed to change the fixed frequency of the pipeline to be vibration-damped connected with the vibration damping device; in addition, the angle and length of the connecting arms are adjustable, and the vibration amplitude of the pipeline to be vibration-damped can be changed.

[0085] The various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. The same or similar parts among the various embodiments can be referred to each other.

[0086] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
