Description

Technical Field

[0001] This utility model relates to the field of generator sets, and in particular to a generator set noise reduction device. Background Technology

[0002] During operation, generator sets generate vibrations due to the movement of power components. When these vibrations cause hard impacts between components, structural noise is produced. To eliminate this noise, buffer pads are typically placed between components to dissipate the vibrational kinetic energy.

[0003] During the assembly process of the generator set, the buffer pad needs to be installed on the bracket first, then the equipment body is placed on the buffer pad, and after further position adjustment, the bracket and the equipment body are finally tightened.

[0004] The purpose of equipment adjustment is to align the connection holes of the buffer pad with the connection holes on the equipment body. However, when the equipment body is fine-tuned on the buffer pad, the buffer pad is flexible and therefore prone to axial flexural deformation, which puts a burden on the adjustment of the equipment body.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0022] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a generator set noise reduction device, which includes: The first connecting part 1 is connected to the device body 00. The first connecting part 1 is a circular connecting plate. The first connecting part 1 has a connecting hole 8 in the middle. During connection, the connecting part on the device body 00 and the first connecting part 1 are connected by a threaded connector (the threaded connector can be a connecting bolt). The inner wall of the connecting hole 8 is provided with a threaded structure. The end of the threaded connector is directly screwed into the connecting hole 8.

[0023] The second connecting part 2 is connected to the bracket 01 and is also a connecting plate; the connection method between the second connecting part 2 and the bracket 01 is the same as the connection method between the first connecting part 1 and the bracket 01.

[0024] The buffer part 3 is connected between the first connecting part and the second connecting part; the buffer part 3 is preferably made of an elastic and deformable material, such as rubber. It has good kinetic energy absorption properties and absorbs the kinetic energy generated by vibration force through its own deformation (compression deformation) during the buffering process, thereby achieving a buffering effect.

[0025] A temporary support 4 is detachably installed between the first connecting part 1 and the second connecting part 2. After the device body 00 is placed on the buffer device, during the position adjustment stage, the temporary support 4 is used to maintain the position of the first connecting part 1 and the second connecting part 2, so that the two have sufficient strength to avoid the flexural deformation caused by the flexibility of the buffer part 3, so that the buffer part 3 does not work, which facilitates the positioning of the connecting hole of the first connecting part 1 and the connecting hole on the device body 00, increases the adjustment accuracy of the device body 00, and improves the calibration efficiency.

[0026] Once the main body 00 is assembled, it enters the buffer working state, and the temporary support part 4 needs to be disassembled to restore the working state of the buffer part 3.

[0027] The temporary support section 4 described in this application has two specific structures.

[0028] In the first embodiment, the temporary support 4 is a ring structure; it has a metal strap with two connecting ends, and the two connecting ends are connected to form a ring. The first connecting part 1 and the second connecting part 2 are provided with corresponding locking protrusions 5 on their opposite sides, which are in the shape of the inner edge of the collar structure; the locking protrusions 5 extend into the inside of the collar structure.

[0029] During the installation of the equipment body 00, the temporary support part 4 of the collar structure cooperates with the locking protrusion 5 to generate a radial support force perpendicular to the axis of the temporary support part 4, which can prevent the first connecting part 1 from shifting position relative to the second connecting part 2.

[0030] The two connecting ends are provided with ear plates 6; during connection, the two ear plates 6 are fitted and fastened together by threaded connectors. After the equipment body 00 is installed, during the disassembly of the temporary support part 4, the aforementioned threaded connectors are removed, forming an opening between the two connecting ends, and the temporary support part 4 can be removed.

[0031] In the second embodiment, the temporary support 4 is a connector with its two ends connected to the first connecting part 1 and the second connecting part 2, respectively. The temporary support 4 is a columnar structure (the columnar structure can be a plug or a threaded column). Taking a threaded column as an example, its end is provided with a threaded structure, and the first connecting part 1 and the second connecting part 2 are respectively provided with connecting holes. The end of the temporary support 4 is screwed into the connecting hole, and the strength of the column itself is used to provide radial support force perpendicular to the axis of the temporary support 4.

[0032] See Figure 5 and Figure 6 Once the main body of the device 00 is installed, the temporary support 4 can be disassembled. Specifically, the end of the installed temporary support 4 extends outward from one of the second connecting parts 2. The extended part is the driving part 7, whose diameter is smaller than the size of the connecting hole. Using a tool (such as a wrench), the driving part is used to rotate and disassemble the temporary support 4 from the connecting hole of the second connecting part 2.

[0033] To further optimize the support effect of the temporary support part 4 and achieve a balance of multi-directional support forces, the connecting hole is located at the center of the first connecting part 1 and the second connecting part 2; furthermore, an obstacle avoidance space is provided in the middle of the buffer part 3, and the temporary support part 4 is placed in the obstacle avoidance space.

[0034] In summary, this utility model provides a generator set noise reduction device, comprising: a first connecting part, connected to the equipment body, the first connecting part being a circular connecting plate; a connecting hole is located in the middle of the first connecting part, and during connection, the connecting part on the equipment body and the first connecting part are connected by a threaded connector (the threaded connector can be a connecting bolt), and the inner wall of the connecting hole is provided with a threaded structure. The end of the threaded connector is directly screwed onto the connecting hole. A second connecting part, connected to the bracket, is also a connecting plate; the connection method between the second connecting part and the bracket is the same as the connection method between the first connecting part and the bracket described above. A buffer part is connected between the first connecting part and the second connecting part; the buffer part is preferably made of an elastic deformable material, such as rubber. It has good kinetic energy absorption properties, and during the buffering process, it absorbs the kinetic energy generated by vibration force through its own deformation (compression deformation), thus achieving a buffering effect. A temporary support part is detachably installed between the first connecting part and the second connecting part for position adjustment after the equipment body is placed on the buffer device.

[0035] This invention utilizes a temporary support to maintain the position of the first connecting part and the second connecting part, ensuring sufficient strength between them to prevent flexural deformation caused by the flexibility of the buffer part, thus preventing the buffer part from working. This facilitates the positioning of the connecting hole of the first connecting part with the connecting hole on the device body, increases the adjustment accuracy of the device body, and improves calibration efficiency.

[0036] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
