Description

Technical Field

[0001] This utility model relates to the field of muffler installation and fixing technology, specifically a muffler fixing device for generator sets that is easy to install. Background Technology

[0002] A silencer is a noise reduction device used in airflow ducts that simultaneously transmit noise. It can be made by using pipes with sound-absorbing linings, bends, or pipes with sudden changes in cross-sectional area or other discontinuous acoustic impedance to attenuate or reflect noise back into the duct.

[0003] During the operation of a generator set, a silencer is an essential component. Its main function is to reduce the noise generated by the generator set during operation and reduce noise pollution to the surrounding environment.

[0004] Existing muffler mounting brackets typically have fixed mounting hole positions. However, due to design errors or deviations during construction, the actual mounting hole positions of the muffler base may differ from the preset hole positions of the mounting bracket. To complete the installation, construction workers often need to use temporary measures such as enlarging the holes or re-welding the brackets. Enlarging the holes may damage the structural strength of the mounting brackets and reduce their load-bearing capacity. Therefore, a muffler fixing device for generator sets that is easy to install is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a generator set muffler fixing device that is easy to install, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a generator set muffler fixing device that is easy to install, including a muffler body, a plurality of bases fixed on the outside of the muffler body, and an adjustment component on one side of the base, the adjustment component being used to adjust the fixed position of the muffler body. The adjustment assembly includes an extension mechanism and a rotation mechanism; The extension mechanism includes a guide rod and a support frame. A sliding plate is fixed to one end of the guide rod, and a first sliding groove is provided on the inner side of the support frame. A limiting groove is provided on one side of the base, and two pressure plates are slidably connected to the inner wall of the limiting groove. A protective layer is adhered to one side of the pressure plates. A first screw is rotatably connected to one side of the pressure plate; The rotating mechanism includes a limiting plate, and a connecting plate is hinged to one side of the limiting plate.

[0007] Preferably, a first flange and a second flange are respectively installed on the outside of the muffler body, and the air inlet end of the first flange is connected to the air outlet end of the generator set through a pipe.

[0008] Preferably, the second flange is used to discharge the silenced gas, and the first flange and the second flange are distributed vertically between them.

[0009] Preferably, the slide plate is slidably connected to the inner side of the first slide groove via a slide rail, and the slide plate is rectangular in shape.

[0010] Preferably, the outer side of the first screw is threaded to one side of the base, one end of the guide rod is fixed to the inner wall of the limiting groove, and the support frame is slidably connected to the inner side of the limiting groove; When the pressure plate and protective layer are attached to the support frame, the support frame is in a clamped and fixed state.

[0011] Preferably, the connecting plate has a waist-shaped hole on one side, and the limiting plate has a second sliding groove on one side.

[0012] Preferably, a second screw is fixed to one side of the connecting plate, and a first nut and a second nut are threaded onto the outer side of the second screw.

[0013] Preferably, the limiting plate is fixed to one end of the support frame; When the first nut and the second nut are loosened, the connecting plate is in a rotating state.

[0014] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects: 1. By pushing the support frame to slide in the limiting groove, the slide plate slides accordingly in the first sliding groove. Rotating the first screw drives the pressure plate to move towards the support frame. After the pressure plate and the support frame are in contact, they form a clamping surface, so that the support frame is in a clamped and fixed state, preventing the support frame from moving in the horizontal direction. The position of the support frame relative to the muffler body can be easily adjusted, so that the approximate fixed position of the muffler body in the installation space can be initially determined, meeting the position requirements of different installation spaces and improving the adaptability of the installation.

[0015] 2. After loosening the first and second nuts, the connecting plate can rotate around the hinge point with the limiting plate. The oblong hole and the second slide groove provide room for rotation, making it easy to adjust the angle of the muffler body to adapt to different installation environments. After adjusting to the appropriate angle, tightening the first and second nuts can fix the connecting plate on the limiting plate. There is no need for construction personnel to use temporary measures such as enlarging holes or re-welding brackets, which simplifies the angle adjustment process. Then, inserting the expansion bolt into the oblong hole and connecting it to the bracket can achieve a firm fixation of the muffler body at that angle position. Attached Figure Description

Example

[0021] Please see Figure 1-5This utility model provides a technical solution: a generator set muffler fixing device that is easy to install, including a muffler body 1, a plurality of bases 3 fixed on the outside of the muffler body 1, and an adjustment component 5 provided on one side of the base 3. The adjustment component 5 is used to adjust the fixed position of the muffler body 1; the adjustment component 5 includes an extension mechanism and a rotation mechanism. The muffler body 1 is equipped with a first flange 2 and a second flange 4 on its outer side. The air inlet end of the first flange 2 is connected to the air outlet end of the generator set through a pipe. The pipe can be a flexible connection. The second flange 4 is used to discharge the silenced gas. The first flange 2 and the second flange 4 are distributed vertically between each other.

[0022] In this embodiment, the muffler body 1 is a disc-type muffler. The muffler body 1 is a DIS45 series manufactured by Changzhou Yichuang Energy Technology Co., Ltd., and the muffler body 1 can be installed horizontally or vertically. Since the structure and operating principle of this type of muffler body 1 are existing technologies, its structure and operating principle will not be described in detail here. The specific muffler body 1 model mentioned in this embodiment is for illustrative purposes only and does not represent that this utility model is limited to a certain commercial product. Any muffler body 1 with a corresponding installation interface can be adapted to this adjustment component 5, and in actual applications, it can be adaptively adjusted according to different muffler bodies 1.

[0023] The extension mechanism includes a guide rod 52 and a support frame 53. A slide plate 59 is fixed to one end of the guide rod 52. A first sliding groove 58 is provided on the inner side of the support frame 53. A limiting groove 54 is provided on one side of the base 3. Two pressure plates 57 are slidably connected to the inner wall of the limiting groove 54. The support frame 53 can move along the direction of the guide rod 52. The slide plate 59 slides in the first sliding groove 58 to provide guidance and stability. A protective layer 55 is adhered to one side of the pressure plate 57. The material of the protective layer 55 can be rubber or silicone. A first screw 56 is rotatably connected to one side of the pressure plate 57. The slide plate 59 is slidably connected to the inner side of the first slide groove 58 via a slide rail. The slide plate 59 is cuboid in shape. The outer side of the first screw 56 is threaded to one side of the base 3. One end of the guide rod 52 is fixed to the inner wall of the limiting groove 54. The support frame 53 is slidably connected to the inner side of the limiting groove 54. When the pressure plate 57 and the protective layer 55 are in contact with the support frame 53, the support frame 53 is in a clamped and fixed state. The pressure plate 57 is made of metal. When the pressure plate 57 is driven by the first screw 56 to form a clamping surface with the support frame 53, the device enters a fixed state. When the pressure plate 57 is in contact with the support frame 53, the support frame 53 is clamped and fixed. The protective layer 55 ensures that the clamping is firm and there is no loosening. Conversely, loosening the first screw 56 can release the support frame 53, allowing position adjustment.

[0024] The rotating mechanism includes a limiting plate 515, with a connecting plate 51 hinged to one side of the limiting plate 515. A slotted hole 510 is formed on one side of the connecting plate 51. The slotted hole 510 and a second sliding groove 511 allow the connecting plate 51 to slide within a certain range when adjusting the angle, providing flexibility. A second sliding groove 511 is also formed on one side of the limiting plate 515. A second screw 514 is fixed to one side of the connecting plate 51. A first nut 512 and a second nut 513 are threaded onto the outer side of the second screw 514. The limiting plate 515 is fixed to one end of the support frame 53. When the first nut 512 and the second nut 513 are loosened, the connecting plate 51 is in a rotating state, allowing for free angle adjustment. Once the angle is determined, tightening the first nut 512 and the second nut 513 locks the connecting plate 51 onto the limiting plate 515, fixing the angle.

[0025] Working principle: When the muffler fixing device is working, the gas passage connection between the muffler body and the generator set must first be completed. The first flange 2 installed on the outside of the muffler body 1 has its air inlet end connected to the air outlet end of the generator set through a pipe. The noisy gas generated by the generator set can enter the interior of the muffler body 1 through this passage for noise reduction treatment. After noise reduction treatment, the gas will be discharged through the second flange 4 installed on the outside of the muffler body 1. The first flange 2 and the second flange 4 are distributed vertically, which helps to optimize the gas flow path in the device and ensure smooth gas entry and exit. The muffler body 1 is hoisted to a certain height, and the approximate direction and spacing of the mounting bracket and the oblong hole are initially positioned. Then, the mounting hole position is pre-aligned with the oblong hole 510. According to the actual installation position requirements, the support frame 53 is pushed to slide in the limiting groove 54, and the slide plate 59 slides accordingly in the first sliding groove 58 to adjust the position of the support frame 53 relative to the muffler body 1, thereby initially determining the approximate fixed position of the muffler body 1 in the installation space. When the position of the support frame 53 is properly adjusted, the first screw 56 is rotated. The first screw 56 drives the pressure plate 57 to move towards the support frame 53. When the pressure plate 57 is in contact with the support frame 53, due to the presence of the protective layer 55, it can increase the friction to ensure a stable clamping and avoid direct contact between the pressure plate 57 and the support frame 53, which would cause wear. At this time, the support frame 53 is in a clamped and fixed state. The pressure plate 57 is driven by the first screw 56 to form a clamping surface with the support frame 53. The device enters a fixed state to prevent the support frame 53 from moving in the horizontal direction. When the angle of the muffler body 1 needs to be adjusted to adapt to different installation environments, loosen the first nut 512 and the second nut 513. At this time, the connecting plate 51 is in a rotating state and can rotate around the hinge point with the limiting plate 515. The oblong hole 510 and the second slide groove 511 provide a certain amount of room for rotation. After adjusting to the appropriate angle, tighten the first nut 512 and the second nut 513 to fix the connecting plate 51 on the limiting plate 515. There is no need for construction personnel to use temporary measures such as enlarging holes or re-welding brackets.

[0026] The expansion bolt is inserted into the inner side of the oblong hole 510. The oblong hole 510 is then recalibrated. The expansion bolt is connected to the bracket for fixing the muffler body 1, thereby fixing the muffler body 1 at this angle position. This determines the final installation angle of the muffler body 1 and completes the installation and fixing of the muffler body 1.

[0027] In summary, by pushing the support frame 53 to slide within the limiting groove 54, and simultaneously sliding the slide plate 59 within the first sliding groove 58, rotating the first screw 56 drives the pressure plate 57 to move towards the support frame 53. After the pressure plate 57 and the support frame 53 come into contact, they form a clamping surface, keeping the support frame 53 in a clamped and fixed state, preventing the support frame 53 from moving horizontally. The position of the support frame 53 relative to the muffler body 1 can be easily adjusted, thereby initially determining the approximate fixed position of the muffler body 1 in the installation space, meeting the positional requirements of different installation spaces, and improving the adaptability of the installation.

[0028] After loosening the first nut 512 and the second nut 513, the connecting plate 51 can rotate around the hinge point with the limiting plate 515. The oblong hole 510 and the second slide groove 511 provide room for rotation, making it convenient to adjust the angle of the muffler body 1 to adapt to different installation environments. After adjusting to the appropriate angle, tightening the first nut 512 and the second nut 513 can fix the connecting plate 51 on the limiting plate 515. There is no need for construction personnel to use temporary measures such as enlarging holes or re-welding brackets, which simplifies the angle adjustment process. Then, the expansion bolt is inserted into the oblong hole 510 and connected to the bracket, which can achieve a firm fixation of the muffler body 1 at this angle position.
