Description

Technical Field

[0001] The present application relates to the technical field of counterweight vibration reduction, and in particular to a counterweight structure, a vibration reduction device and an air conditioner. Background Art

[0002] Natural frequency is an inherent property of the structure. During the operation of the air conditioner, the vibration of the compressor will be transmitted to the pipeline. When the natural frequency of the pipeline is the same as or close to the operating frequency of the compressor, it will cause resonance between the compressor and the pipeline, thereby causing abnormal noise to be amplified. In severe cases, pipe cracks and breakages may occur.

[0003] In related technologies, to suppress pipeline vibration and noise radiation, counterweights such as rubber blocks or damping blocks are typically fixed to the pipeline, thereby changing the pipeline's natural frequency to avoid resonance points. A single counterweight can only be fixed at one location in the pipeline for counterweighting, and its size and mass are not adjustable. However, variable-frequency compressors place varying demands on counterweights as frequency changes, and different pipeline sizes also place varying demands on counterweights.

Therefore, it cannot be understood as a limitation on this application.

[0035] The embodiment of the present application provides a counterweight structure to improve the problem that existing counterweights are difficult to meet the counterweight requirements of different application scenarios.

[0036] In the embodiments of this application, Figure 1 and Figure 2 As shown, the counterweight structure 1 includes a shell 11, a piston 12 and a driving component 13, wherein a first accommodating chamber 111 is provided inside the shell 11, and the piston 12 is adapted to be arranged in the first accommodating chamber 111 to separate the first accommodating chamber 111 into a first cavity 1111 and a second cavity 1112, the first cavity 1111 and the second cavity 1112 are arranged in sequence and connected in the up and down directions, and the first cavity 1111 and the second cavity 1112 are respectively filled with damping fluid; the driving component 13 drives the piston 12 to move so that the damping fluid in the first cavity 1111 flows into the second cavity 1112 or the damping fluid in the second cavity 1112 flows into the first cavity 1111, thereby adjusting the center of gravity position of the counterweight structure 1.

[0037] In other words, the movement of the piston 12 can change the volume ratio of the first cavity 1111 and the second cavity 1112, and at the same time, the damping fluid in the first cavity 1111 flows into the second cavity 1112, or the damping fluid in the second cavity 1112 flows into the first cavity 1111, thereby correspondingly changing the weight ratio of the damping fluid in the first cavity 1111 to the damping fluid in the second cavity 1112, so that the center of gravity of the counterweight structure 1 moves up or down accordingly. The counterweight structure 1 provided in the embodiment of the present application meets the counterweight requirements of different application scenarios by adjusting the center of gravity of the counterweight, and has the advantages of simple structure, flexibility and convenience, and a wide range of applications.

[0038] It should be noted that the volumes of the first cavity 1111 and the second cavity 1112 are variable. When the piston 12 moves to the top of the first accommodating cavity 111, the volume of the first cavity 1111 is 0; when the piston 12 moves to the bottom of the first accommodating cavity 111, the volume of the second cavity 1112 is 0. To facilitate the adjustment of the center of gravity of the counterweight structure 1, the density of the piston 12 is different from the density of the damping fluid.

[0039] In the embodiment of the present application, the driving component 13 drives the piston 12 to move in the vertical direction. Specifically, the driving component 13 drives the piston 12 to move in the direction of gravity. The shape of the piston 12 is not specifically limited. The shape of the piston 12 can be, for example, an I-shaped, disc-shaped, cylindrical, or cylindrical.

[0040] In order to facilitate the adjustment of the center of gravity of the counterweight structure 1, in some embodiments of the present application, continue to refer to Figure 1 and Figure 2The counterweight structure 1 further includes a flow channel 14 provided on the piston 12 or the housing 11, and the flow channel 14 connects the first cavity 1111 and the second cavity 1112. It is understandable that at least part of the flow channel 14 is located inside the housing 11, for example, the entire flow channel 14 is located inside the first accommodating cavity 111, or the entire flow channel 14 is located outside the first accommodating cavity 111 and the entire flow channel 14 is located inside the housing 11, or part of the flow channel 14 is located inside the housing 11 and the remaining part of the flow channel 14 is located outside the housing 11. The cross-sectional shape of the flow channel 14 is not specifically limited, for example, it can be rectangular, S-shaped, T-shaped, etc., and the number of the flow channels 14 can be one or more.

[0041] In some embodiments of this application, see Figure 1 The flow channel 14 is provided through the piston 12. The position where the flow channel 14 is provided through the piston 12 is not specifically limited. For example, if the piston 12 is I-shaped, the flow channel 14 is provided through the middle of the piston 12.

[0042] In other embodiments of the present application, please refer to Figure 2 The flow channel 14 is disposed inside the housing 11 and outside the first accommodating cavity 111. The communication positions of the flow channel 14 and the first cavity 1111 and the communication positions of the flow channel 14 and the second cavity 1112 are not specifically limited. For example, the communication port between the first cavity 1111 and the flow channel 14 is disposed on a side of the first cavity 1111 away from the second cavity 1112, and the communication port between the second cavity 1112 and the flow channel 14 is disposed on a side of the second cavity 1112 away from the first cavity 1111.

[0043] It should be noted that in order to facilitate the regulation of the counterweight center of gravity of the counterweight structure 1, except for the flow channel 14, there is no other connecting channel between the first cavity 1111 and the second cavity 1112, for example, there is no gap between the side wall of the piston 12 and the side wall of the first accommodating cavity 111.

[0044] In some embodiments of this application, see Figure 1 and Figure 2The driving component 13 includes a motor 131 and a telescopic link 132 arranged in the shell 11. At least part of the telescopic link 132 is located in the first accommodating chamber 111. One end of the telescopic link 132 is connected to the motor 131, and the other end is connected to the piston 12. Under the driving action of the motor 131, the telescopic link 132 is in a stretched state or a contracted state to drive the piston 12 to move. Specifically, when the telescopic link 132 is in a retracted state, the piston 12 moves upward, and based on the extrusion effect, the damping fluid in the first cavity 1111 flows into the second cavity 1112 through the flow channel 14, thereby achieving the purpose of moving the center of gravity of the counterweight downward, and the degree of downward movement of the center of gravity of the counterweight is determined according to the counterweight requirements of the application scenario; when the telescopic link 132 is in a stretched state, the piston 12 moves downward, and based on the extrusion effect, the damping fluid in the second cavity 1112 flows into the first cavity 1111 through the flow channel 14, thereby achieving the purpose of moving the center of gravity of the counterweight upward, and the degree of upward movement of the center of gravity of the counterweight is determined according to the counterweight requirements of the application scenario.

[0045] The motor 131 can be disposed on the outer surface of the housing 11 or inside the housing 11. The telescopic link 132 can be disposed inside the housing 11, with part of the telescopic link 132 located outside the first accommodating chamber 111 or the entire telescopic link 132 located inside the first accommodating chamber 111; alternatively, part of the telescopic link 132 is located outside the housing 11.

[0046] It is understood that the driving component 13 can be a telescopic motor, and the telescopic shaft of the telescopic motor is connected to the piston 12. The driving component 13 can also be a power assembly commonly used in the art, for example: the power assembly includes a gear, a rack and a motor, the gear is meshed with the rack, the drive shaft of the motor is connected to the gear, and the piston 12 is fixed to the rack.

[0047] The embodiment of the present application also provides a vibration reduction device 10, such as Figures 1 to 6 As shown, vibration damping device 10 includes at least one counterweight structure 1 and an assembly structure 2.

Because vibration damping device 10 utilizes all the technical solutions of all the above-described embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above-described embodiments, and a detailed description thereof will not be repeated here.

[0048] In the embodiment of the present application, the vibration reduction device 10 adjusts the center of gravity of the counterweight structure 1 to change the natural frequency of the pipeline 20, thereby avoiding resonance of the pipeline 20 and effectively reducing the vibration of the pipeline 20. It has good vibration reduction and noise reduction effects, and improves the stress condition of the pipeline 20, reducing the risk of pipe cracking and pipe breakage. The vibration reduction device 10 can be applied to vibration reduction of different types of pipelines.

[0049] To further improve the vibration reduction effect and applicability of the vibration reduction device 10, in some embodiments of the present application, the vibration reduction device 10 includes a plurality of counterweight structures 1, which are sequentially and spaced apart and arranged on the assembly structure 2 around the pipeline 20. It will be understood that the plurality of counterweight structures 1 enclose a space 3 for assembling the pipeline 20.

[0050] As an example, continue to see Figure 3 and Figure 4 The vibration reduction device 10 includes two counterweight structures 1, which are arranged in sequence on the assembly structure 2 around the pipeline 20. Each counterweight structure 1 includes a first surface 15 close to the other counterweight structure. The first surfaces 15 of the two counterweight structures 1 enclose a space 3, and the pipeline 20 is arranged in the space 3.

[0051] In some embodiments of this application, see Figures 3 to 6 The assembly structure 2 includes a mounting plate 21 and a clamp 22 arranged on the mounting plate 21. The mounting plate 21 is used to support the counterweight structure 1, and the clamp 22 is used to tighten and fix the counterweight structure 1 and the pipeline 20.

[0052] In order to further improve the adaptability of the vibration damping device 10 to pipelines 20 of different diameters, in some embodiments of the present application, the clamp 22 includes a first hoop 221, a second hoop 222 and a tightness adjustment portion 223. The tightness adjustment portion 223 is used to connect the first hoop 221 and the second hoop 222 and adjust the length of the clamp 22 to adjust the tightness of the clamp 22 on the counterweight structure 1 and the pipeline 20, thereby realizing the regulation of the size of the space 3 enclosed by multiple counterweight structures 1 to be suitable for assembling pipelines 20 of different diameters.

[0053] Specifically, see Figures 1 to 6 The mounting plate 21 includes a first side wall 211 and a second side wall 212 disposed opposite each other. One end of a first hoop 221 is connected to the first side wall 211, and the other end of the first hoop 221 is connected to the second hoop 222. One end of the second hoop 222 is connected to the second side wall 212, and the other end of the second hoop 222 is connected to the first hoop 221, so that a second accommodating cavity 25 is formed between the mounting plate 21 and the clamp 22. The counterweight structure 1 is disposed in the second accommodating cavity 25. The housing 11 of the counterweight structure 1 has an arcuate segment adapted to abut against the first hoop 221 or the second hoop 222.

[0054] The tension adjusting portion 223 is used to adjust the degree of interlacing, overlapping, or gap between the other end of the first hoop 221 and the other end of the second hoop 222, so as to adjust the degree of tightening of the clamp 22 on the counterweight structure 1 and the pipeline 20. The tension adjusting portion 223 includes, for example, a bolt.

[0055] In order to fix the counterweight structure 1 and facilitate the adjustment of the degree of tightening of the clamp 22 on the counterweight structure 1 and the pipeline 20, in some embodiments of the present application, continue to refer to Figures 1 to 6 The assembly structure 2 further includes a latch 23. The housing 11 of the counterweight structure 1 is provided with a slot adapted to fit the latch 23.
