[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.
[0033] Please refer to the following Figures 1 to 3 The vibration reduction device, the compressor and the air conditioner according to the embodiments of the present utility model are described.
[0034] like Figures 1 to 3 As shown, the vibration damping device of the present embodiment includes: a pipe clamp 1, a counterweight 3, and an elastic member 2. The pipe clamp 1 comprises a connecting portion 11 and two clamping portions 12, one mounted on either side of the connecting portion 11 along its length. The clamping portions 12 define a clamping cavity 121 for clamping the pipeline 6. The counterweight 3 is mounted on the connecting portion 11 and positioned between the two clamping portions 12. The elastic member connects the clamping portions 12 and the counterweight 3. It is understood that the elastic member 2 can elastically deform under the action of an external force.
[0035] According to the vibration damping device of the embodiment of the present invention, the two clamping portions 12 of the pipe clamp 1 can respectively clamp the pipeline 6 on both sides of the connecting portion 11 to secure the pipeline 6. When the pipeline 6 vibrates, the counterweight 3 can vibrate (i.e., slide slightly) on the connecting portion 11 under the action of inertia, thereby generating a force on the pipeline 6 in the opposite direction of the vibration of the pipeline 6, thereby reducing the vibration of the pipeline 6. Under the elastic damping action of the elastic member 2, the elastic member 2 can absorb and dissipate the energy generated by the relative movement of the counterweight 3 and the pipeline 6, thereby further suppressing the vibration of the pipeline 6. Therefore, the vibration damping device of the embodiment of the present invention has a reasonable structural design and a good vibration reduction effect.
[0036] It is understandable that the vibration reduction principle of the vibration reduction device of the embodiment of the present invention is substantially the same as the vibration reduction principle of the tuned mass damper (TMD). When the pipeline 6 vibrates, the pipeline 6 will drive the vibration reduction device to move together. At this time, the counterweight block 3 in the vibration reduction device will vibrate in the opposite direction to the vibration of the pipeline 6 due to inertia. By designing the material properties of the elastic member 2 and adjusting the weight of the counterweight block 3, the vibration frequency of the counterweight block 3 is close to or consistent with the vibration frequency of the pipeline 6. Then, the vibration of the counterweight block 3 will generate a force on the pipeline 6 in the opposite direction of the vibration of the pipeline 6, thereby reducing the vibration of the pipeline 6. In addition, due to the elastic damping effect of the elastic member 2, the elastic member 2 will absorb and dissipate the energy generated by the relative movement between the counterweight block 3 and the pipeline 6 during the vibration of the pipeline 6, further suppressing the vibration of the pipeline 6.
[0037] Therefore, the vibration device has high vibration energy absorption rate, can effectively inhibit vibration of the air conditioner outdoor unit pipeline 6 system, greatly improves the problem of pipeline 6 stress overrun and noise deterioration, and reduces the maintenance cost in the later period.
[0038] For example, the connecting part 11 is a rod-shaped structure, and the connecting part 11 is used to limit the distance between the two clamping parts 12, so as to prevent the pipe clamp 1 from changing the frequency of the vibration device due to extrusion on the elastic member 2 during use.
[0039] Optionally, the elastic member 2 comprises two elastic blocks 21, and the two elastic blocks 21 are arranged on two sides of the counterweight block 3 along the length direction (such as the left-right direction) of the connecting part 11, respectively. Figure 1 The two elastic blocks 21 are connected with the two clamping parts 12, respectively, one end of each elastic block 2 is connected with the clamping part 12, and the other end is connected with the counterweight block 3.
[0040] It can be understood that one elastic block 21 is connected between one clamping part 12 and one side of the counterweight block 3, and the other elastic block 21 is connected between the other clamping part 12 and the other side of the counterweight block 3.
[0041] For example, the elastic block 21 is made of natural rubber or synthetic rubber, and provides stiffness and damping for the counterweight block 3.
[0042] Optionally, the elastic block 21 and the counterweight block 3 are bonded or vulcanized. In other words, the elastic block 21 and the counterweight block 3 can be fixed by using the glue bonding method, or can be fixed together by using the vulcanization method. When the vibration device vibrates, the elastic block 21 and the counterweight block 3 can vibrate synchronously to ensure the reliability of the connection between the elastic block 21 and the counterweight block 3, and is beneficial to improve the damping effect.
[0043] Further, the elastic block 21 and the outer surface of the clamping part 12 are bonded or vulcanized. In other words, the elastic block 21 and the clamping part 12 can be fixed by using the glue bonding method, or can be fixed together by using the vulcanization method. When the vibration device vibrates, the elastic block 21 and the clamping part 12 can move synchronously to ensure the reliability of the connection between the elastic block 21 and the clamping part 12, and is beneficial to improve the damping effect.
[0044] Specifically, the outer surface of the clamping portion 12 is cylindrical, and the end surface of the elastic block 21 connected with the clamping portion 12 has a semi-cylindrical recessed surface 211 which is in abutment with the outer surface of the clamping portion 12. The recessed surface 211 and the outer surface of the clamping portion 12 can be connected in abutment by means of gluing or vulcanization, thereby increasing the contact area of the clamping portion 12 and the elastic block 21 and improving the damping effect.
[0045] In some embodiments, as shown in Figure 3 At least one of the elastic block 21 and the counterweight block 3 is provided with a sliding groove 212, which is arranged on the side wall surface of the elastic block 21 and / or the counterweight block 3 and extends along the length direction of the connecting portion 11. The connecting portion 11 is slidingly fitted in the sliding groove 212.
[0046] For example, the sliding groove 212 is arranged on the elastic block 21, or the sliding groove 212 is arranged on the counterweight block 3. For another example, the sliding groove 212 is arranged on both the elastic block 21 and the counterweight block 3.
[0047] In the examples of the present application, the sliding groove 212 is arranged on both the elastic block 21 and the counterweight block 3 and is located on the same straight line, and the connecting portion 11 is located in the sliding groove 212. When the damping device vibrates, the elastic block 21 and the counterweight block 3 can both vibrate (i.e., slightly slide) along the length direction of the connecting portion 11 under the constraint of the connecting portion 11 and the sliding groove 212, so as to form the damping structure of the tuned mass damper. On the other hand, since the elastic block 21 and the counterweight block 3 are fitted with the connecting portion 11 through the sliding groove 212, the assembly work of the damping device can be facilitated, and the damping device is easy to disassemble and assemble, so as to facilitate the later maintenance and maintenance.
[0048] For example, as shown in Figure 3 The sliding groove 212 is provided with an opening 213 on the side orthogonal to the length direction of the connecting portion 11, so as to facilitate the disassembly and assembly of the elastic block 21 and the counterweight block 3.
[0049] In some embodiments, as shown in Figure 1 and Figure 3 The damping device further comprises an adjusting block 4, and the adjusting block 4 is at least partially inserted into the counterweight block 3. The portion of the adjusting block 4 inserted into the counterweight block 3 is adjustable. It can be understood that the technician can adjust the insertion position or insertion depth of the adjusting block 4 in the counterweight block 3, so as to change the vibration frequency of the damping device, so as to adjust the vibration frequency of the "counterweight block 3 + adjusting block 4" to be close to or consistent with the vibration frequency of the pipeline 6, thereby achieving accurate adjustment of the TMD frequency and achieving the best damping effect.
[0050] Optionally, the adjusting block 4 is a plurality of adjusting blocks 4, and the plurality of adjusting blocks 4 are arranged on the counterweight block 3 in the height direction (e.g., the up-down direction of Figure 1 , so as to expand the application range of the damping device and make the frequency adjustment of the damping device more flexible.
[0051] For example, there are four adjustment blocks 4, two of which are installed in the thickness direction of the counterweight 3 (such as Figure 1 The other two adjustment blocks 4 are installed in the thickness direction of the counterweight 3 (such as Figure 1 the other side of the front-to-back direction).
[0052] In the example of this application, Figure 1 and Figure 3 As shown, the adjustment block 4 is a threaded member. A threaded hole is provided on the wall of the counterweight 3, and the threaded member is adjustably inserted into the threaded hole. The threaded member can be screwed into the threaded hole a different number of times to change the relative position of the threaded member and the counterweight 3, thereby improving the convenience of adjusting the adjustment block 4.
[0053] Of course, the vibration damping device can also be replaced with different types or materials of screw parts to adjust the vibration frequency of the vibration damping device.
[0054] In some embodiments, as Figure 1 As shown, the vibration damping device includes a flexible member 5, which can be surrounded by a fastening ring 51. The pipe clamp 1, elastic member 2, and counterweight 3 are all disposed within the fastening ring 51, and the fastening ring 51 is connected to the clamping portion 12. It can be understood that the flexible member 5 is disposed around the outer circumference of the pipe clamp 1 to bundle the pipe clamp 1, elastic member 2, and counterweight 3 into one body, thereby improving the reliability of the connection between the vibration damping device and the pipeline 6 and reducing the probability of the vibration damping device falling off.
[0055] For example, the flexible member 5 is a cable tie, which is wrapped around the outer circumference of the pipe clamp 1 and forms a fastening ring 51 for binding the pipe clamp 1 , the elastic member 2 and the counterweight 3 .
[0056] Optionally, a gap is provided between the elastic member 2 and the counterweight 3 and the inner wall of the fastening ring 51. It is understood that neither the elastic member 2 nor the counterweight 3 contacts the flexible member 5 (cable tie), thereby preventing friction between the flexible member 5 (cable tie) and the elastic member 2 and the counterweight 3 when the vibration damping device is operating, thereby avoiding a reduction in the vibration damping effect and extending the service life of the flexible member 5 (cable tie).
[0057] For example, the outer diameters of the two clamping parts 12 are both larger than the thickness direction of the elastic member 2 and the counterweight 3 (e.g. Figure 1 The dimension of the front-to-back direction) is such that the fastening ring 51 can be stretched apart by the two clamping parts 12 to prevent the inner wall of the fastening ring 51 from contacting the elastic member 2 and the counterweight 3.
[0058] Alternatively, as Figure 1 and Figure 2As shown, the outer wall surface of the clamping portion 12 is provided with a matching groove 124, and the fastening ring 51 is installed in the matching groove 124, so that the matching groove 124 can limit the fastening ring 51, thereby reducing the probability of displacement and disengagement of the fastening ring 51 from the clamping portion 12.
[0059] Optionally, as shown in Figure 1 and Figure 2 , the inner wall surface of the clamping cavity 121 is provided with an elastic buffer layer 123. For example, the elastic buffer layer 123 is a buffer rubber, which is in contact with the pipeline 6 to prevent the pipeline 6 from being worn and damaged, and is beneficial to improve the damping effect of the damping device.
[0060] As shown in Figure 2 , the clamping portion 12 is provided with an opening 122 along one side of the radial direction, and the opening 122 is in communication with the clamping cavity 121. The opening 122 penetrates the clamping portion 12 along the axial direction of the clamping cavity 121, and the clamping portion 12 is a plastic structure, so that the clamping portion 12 can be deformed to a certain extent, so that the pipeline 6 can be clamped into the clamping cavity 121 from the opening 122.
[0061] Specifically, the TMD parameter design of the damping device of the embodiment of the utility model is as follows.
[0062] In the TMD design process, factors such as the initial vibration condition of the structure, the selection of system parameters, and the selection of damper type need to be considered. At the same time, the reliability, safety and economy of the design need to be considered to ensure the practicability and feasibility of the TMD.
[0063] According to the fixed-point theory, the parameters of the TMD are determined by the optimal frequency ratio f opt and the damping ratio ξ dopt of the TMD:
[0064]
[0065] Wherein, f opt and ξ dopt represent the optimal frequency ratio and the damping ratio of the TMD and the mode to be controlled by the pipeline respectively; μ represents the mass ratio of the mass of the TMD to the mass of the mode to be controlled by the pipeline structure (such as the mass of the pipeline and the stiffness of the pipeline), which can be taken as a specified value.
[0066] According to formulas (1-1) and (1-2), the optimization parameters of the TMD can be further calculated, wherein the stiffness k opt , the mass m d and the damping c opt of the TMD are calculated as follows:
[0067] c opt =2ξ dopt f opt ωx m d (1-3)
[0068]
[0069] m d =μm x (1-5)
[0070] wherein, x is the order of the controlled structure, ω represents the inherent frequency of the structure, ω x represents the xth order inherent frequency of the structure, m x is the xth order equivalent mass of the pipeline.
[0071] It can be understood that the design process of the vibration reduction device of the embodiment of the utility model is as follows.
[0072] (1) Design the size of each component of the vibration reduction device according to the size and spacing of the pipeline;
[0073] (2) Design the TMD parameters according to the mass ratio and the main structure frequency of the pipeline;
[0074] (3) Select the counterweight according to the TMD mass parameters, and select the appropriate rubber material according to the TMD stiffness and damping;
[0075] (4) Manufacture the TMD vibration reduction device and perform device frequency measurement and fine tuning;
[0076] (5) Determine the installation position of the TMD vibration reduction device and fix it with a cable tie;
[0077] (6) Use the TMD vibration reduction device to consume the pipeline vibration energy and reduce the pipeline vibration amplitude.
[0078] In summary, the vibration reduction device of the embodiment of the utility model has at least the following technical effects:
[0079] (1) The directional frequency vibration reduction effect of the vibration reduction device is excellent. The vibration reduction device can be designed and tuned according to a specific vibration frequency, so that its inherent frequency matches the main vibration frequency of the pipeline 6, thereby achieving optimal vibration reduction effect in a specific frequency range. While reducing the vibration amplitude of the pipeline 6, the stress of the pipeline 6 is greatly relieved.
[0080] (2) The volume and weight of the vibration reduction device are more optimized. The vibration reduction device can achieve optimal vibration reduction effect under smaller volume and weight through optimized material selection and design, which is particularly important for air conditioner outdoor unit structures with limited installation space.
[0081] (3) The vibration reduction device has strong adjustability. The mass of the counterweight 3 can be adjusted by the threaded part, thereby realizing precise adjustment of the frequency of the vibration reduction device and achieving the best vibration reduction effect.
[0082] (4) The damping device has multiple damping modes. On one hand, the vibration of the counterweight 3 of the damping device generates an action force on the pipeline 6 in the opposite direction of the vibration direction, so as to reduce the vibration of the pipeline 6; on the other hand, the elastic block 21 has a damping property and can absorb and dissipate the energy generated by the relative movement between the counterweight 3 and the pipeline 6 during the vibration, so as to further suppress the vibration of the pipeline 6.
[0083] The compressor of another embodiment of the utility model, including compressor body (not show), pipeline 6 and damping device. Pipeline 6 is connected with compressor body, and pipeline 6 includes first pipe section 61 and second pipe section 62, and damping device is the damping device of the utility model, and the clamping cavities 121 of the two clamping parts 12 respectively clamps first pipe section 61 and second pipe section 62.
[0084] According to the compressor of the embodiment of the utility model, the two clamping parts 12 of the pipe clamp 1 can respectively clamp the first pipe section 61 and the second pipe section 62 on the two sides of the connecting part 11 to fix the pipeline 6. When the pipeline 6 vibrates, the counterweight 3 can vibrate (i.e. slightly slide) on the connecting part 11 under the action of inertia to generate an action force on the pipeline 6 in the opposite direction of the vibration direction of the pipeline 6, so as to reduce the vibration of the pipeline 6. Under the elastic damping action of the elastic member 2, the elastic member 2 can absorb and dissipate the energy generated by the relative movement between the counterweight 3 and the pipeline 6 to further suppress the vibration of the pipeline 6. Therefore, the structure of the damping device of the embodiment of the utility model is reasonable, and the damping effect is good.
