Description

Technical Field

[0001] This utility model relates to the field of diesel engine noise reduction technology, and in particular to a noise reduction mechanism for diesel internal combustion engine units. Background Technology

[0002] During the operation of diesel internal combustion engine units, the noise they generate not only pollutes the surrounding environment but may also affect the health of operators and the normal monitoring and maintenance of equipment. In practical applications, a noise reduction mechanism for diesel internal combustion engine units typically requires the following technologies: 1. Sound insulation technology: Using sound insulation materials, such as sound-absorbing cotton, sound insulation felt, damping plates, etc., to wrap the diesel internal combustion engine unit or build a sound insulation cover. The sound-absorbing cotton can absorb sound wave energy and convert sound energy into heat energy, thereby reducing the propagation of noise. 2. Vibration reduction technology: The use of shock absorbers, vibration damping pads and other devices reduces the vibration generated by the diesel internal combustion engine unit during operation, thereby reducing the noise caused by vibration. The shock absorber usually uses elastic elements such as springs and rubber to absorb and buffer the vibration energy generated by the unit and reduce the transmission of vibration to the foundation structure.

[0003] Existing diesel internal combustion engines will generate vibrations during use, resulting in strong noise. This noise not only pollutes the surrounding environment but may also affect the health of operators and the normal monitoring and maintenance of equipment. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a noise reduction mechanism for diesel internal combustion engine units, solving the technical problem that existing diesel internal combustion engines will generate vibrations during use, resulting in strong noise. This noise not only pollutes the surrounding environment but may also affect the health of operators and the normal monitoring and maintenance of equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A noise reduction mechanism for a diesel internal combustion engine includes a base, a mounting plate slidably mounted on the base, dampers uniformly mounted between the mounting plate and the base, springs mounted on the dampers, first magnets fixedly mounted at each of the four corners of the base, and second magnets fixedly mounted at each of the four corners of the mounting plate, wherein the opposing magnetic poles of the first magnets and the second magnets are the same.

[0006] Preferably, support legs are slidably installed at all four corners of the base, and threaded rods are rotatably installed at all four corners of the base.

[0007] Preferably, a dial is fixedly installed on the threaded rod.

[0008] Preferred: Threaded connection between threaded rod and support leg.

[0009] Preferably, a rubber pad is fixedly installed at the bottom of the support leg.

[0010] Preferably, the mounting plate has mounting holes evenly spaced.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. During installation, the diesel internal combustion engine can be fixed to the mounting plate through the mounting holes using bolts. The vibration generated by the internal combustion engine during operation will cause the mounting plate to slide on the base, thereby compressing the damper and spring. The damper and spring can absorb the energy generated by the vibration. At the same time, during the sliding of the mounting plate, the first magnet and the second magnet will consume the vibration energy through the repulsive force between them, thus achieving the effect of noise reduction of the internal combustion engine.

[0012] 2. During installation, the diesel internal combustion engine can be fixed to the mounting plate through the mounting holes using bolts. Rotating the dial will cause the threaded rod to rotate. Since the threaded rod and the support leg are threadedly connected, the rotation of the threaded rod will push the support leg to slide. When installing on a level surface, the support leg can be slid by rotating the dial to change the installation height. All four dials rotate the same number of times. When using on an uneven surface, the support leg can be adjusted independently to keep the mounting plate level on uneven surfaces. Attached Figure Description

[0016] This application provides a noise reduction mechanism for diesel internal combustion engine units, effectively solving the problem that existing diesel internal combustion engines generate vibrations during operation, resulting in significant noise. This noise not only pollutes the surrounding environment but may also affect the health of operators and hinder the normal monitoring and maintenance of the equipment. During installation, the diesel internal combustion engine can be bolted to the mounting plate through mounting holes. The vibrations generated by the internal combustion engine during operation will cause the mounting plate to slide on the base, thereby reducing noise. The damper and spring are compressed, and the damper, together with the spring, can absorb the energy generated by vibration. At the same time, during the sliding of the mounting plate, the first magnet and the second magnet will dissipate the vibration energy through the repulsive force between them, thus achieving the effect of reducing noise from the internal combustion engine. During installation, the diesel internal combustion engine can be fixed to the mounting plate through the mounting holes with bolts. Turning the dial will cause the threaded rod to rotate. Since the threaded rod and the support leg are threadedly connected, the rotation of the threaded rod will push the support leg to slide. When installing on a level surface, the support leg can be slid by rotating the dial to change the installation height. All four dials rotate the same number of times. When used on uneven surfaces, the support leg can be adjusted independently to keep the mounting plate level on uneven surfaces. Example

[0017] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem that existing diesel internal combustion engines will generate vibration during use, resulting in strong noise. The noise generated not only pollutes the surrounding environment but may also affect the health of operators and the normal monitoring and maintenance of equipment. The overall idea is as follows: To address the problems existing in the prior art, this utility model provides a noise reduction mechanism for diesel internal combustion engine units, including a base 1, an mounting plate 2 slidably mounted on the base 1, dampers 3 uniformly mounted between the mounting plate 2 and the base 1, and springs 4 mounted on the dampers 3.

[0018] A first magnet 5 is fixedly installed at each of the four corners of the base 1, and a second magnet 6 is fixedly installed at each of the four corners of the mounting plate 2. The opposing magnetic poles of the first magnet 5 and the second magnet 6 are the same. Support legs 7 are slidably installed at each of the four corners of the base 1.

[0019] Threaded rods 8 are rotatably installed at the four corners of the base 1. A dial wheel 9 is fixedly installed on the threaded rod 8. The threaded rod 8 and the support leg 7 are threadedly connected. A rubber pad 11 is fixedly installed at the bottom of the support leg 7. Mounting holes 12 are evenly opened on the mounting plate 2.

[0020] Base 1: As the basic support structure of the entire noise reduction mechanism, it provides a mounting carrier for components such as mounting plate 2, support leg 7, and threaded rod 8. It bears the weight of mounting plate 2 and the diesel internal combustion engine installed on it, and transfers the weight to the ground through support leg 7. At the same time, it cooperates with mounting plate 2 to allow mounting plate 2 to slide on it, so as to achieve buffering and noise reduction of internal combustion engine vibration. Mounting plate 2: Slidably mounted on base 1 for mounting diesel internal combustion engine. The diesel internal combustion engine is fixed on it with bolts through mounting holes 12. When the diesel engine vibrates during operation, mounting plate 2 will slide on base 1, thereby compressing damper 3 and spring 4, and transferring vibration energy to damper 3 and spring 4 for absorption. At the same time, it interacts with the magnets at the four corners of base 1 to consume vibration energy using magnetic force, thereby achieving noise reduction. Damper 3: Installed between mounting plate 2 and base 1. When mounting plate 2 slides on base 1 due to internal combustion engine vibration, damper 3 is compressed. Its main function is to convert the mechanical energy of vibration into heat energy and other forms of energy, thereby consuming vibration energy and reducing vibration transmission. It is one of the key components for achieving noise reduction. Spring 4: Installed on damper 3, working in conjunction with damper 3. When mounting plate 2 slides and compresses damper 3, spring 4 is also compressed. It uses its own elastic potential energy to store and release energy, buffer the impact of vibration, and together with damper 3 absorb the vibration energy generated by the operation of internal combustion engine, reducing noise. First magnet 5: Fixedly installed at the four corners of the base 1, opposite to the second magnet 6 at the four corners of the mounting plate 2. Since the first magnet 5 and the second magnet 6 have the same magnetic poles on opposite sides, when the mounting plate 2 slides due to vibration, a repulsive force is generated between them. This repulsive force can consume vibration energy and further enhance the noise reduction effect. The second magnet 6 is fixedly installed at the four corners of the mounting plate 2 and interacts with the first magnet 5 at the four corners of the base 1. Through the repulsive force between it and the first magnet 5, it consumes vibration energy during the vibration and sliding process of the mounting plate 2, and assists the damper 3 and spring 4 to achieve noise reduction. Support legs 7: Slidably installed at the four corners of the base 1, their main function is to support the base 1 and all components installed on it, and transfer the weight to the ground. In addition, by rotating the threaded rod 8, the support legs 7 can slide up and down, thereby adjusting the height of the entire noise reduction mechanism. Under different terrain conditions, the mounting plate 2 is kept in a horizontal state, ensuring the stable operation of the diesel internal combustion engine, which indirectly helps to achieve the noise reduction effect. Threaded rod 8: Rotatably mounted at the four corners of the base 1 and threadedly connected to the support leg 7. By rotating the threaded rod 8, the support leg 7 can be pushed up and down to achieve precise adjustment of the height of the support leg 7. The dial 9 fixed on the threaded rod 8 makes it convenient for the operator to rotate the threaded rod 8, making the adjustment operation more convenient. Dial wheel 9: Fixedly mounted on threaded rod 8, providing an application point for the operator to easily rotate threaded rod 8, thereby adjusting the height of support leg 7. By rotating dial wheel 9, the operator can more easily and accurately control the sliding of support leg 7 to adapt to different ground conditions and ensure that mounting plate 2 is level. Rubber pad 11: It is fixedly installed at the bottom of the support leg 7 to increase the friction between the support leg 7 and the ground, prevent the support leg 7 from sliding on the ground, and make the entire noise reduction mechanism more stable. At the same time, the rubber pad 11 has a certain elasticity, which can further buffer the vibration from the ground and assist the entire mechanism in achieving noise reduction. Mounting holes 12 are evenly spaced on the mounting plate 2 and are used to fix the diesel internal combustion engine to the mounting plate 2 with bolts, ensuring a stable connection between the diesel internal combustion engine and the mounting plate 2. This allows the mounting plate 2 to effectively transmit the vibrations generated during the operation of the internal combustion engine, so that noise reduction can be achieved through components such as dampers 3, springs 4, and magnets.

[0021] Working principle: The first step is to fix the diesel internal combustion engine to the mounting plate 2 through the mounting hole 12 with bolts. Turning the dial 9 will rotate the threaded rod 8. Since the threaded rod 8 is threadedly connected to the support leg 7, the rotation of the threaded rod 8 will push the support leg 7 to slide. When installing on a level surface, the support leg 7 can be slid by rotating the dial 9 to change the installation height. All four dials 9 rotate the same number of turns. When using on an uneven surface, the support leg 7 can be adjusted independently so that the mounting plate 2 can be kept level on an uneven surface.

[0022] In the second step, the vibration generated by the internal combustion engine during operation will cause the mounting plate 2 to slide on the base 1, thereby compressing the damper 3 and the spring 4. The damper 3 and the spring 4 can absorb the energy generated by the vibration. At the same time, during the sliding of the mounting plate 2, the first magnet 5 and the second magnet 6 will consume the energy of the vibration through the repulsive force between them, thus achieving the effect of reducing the noise of the internal combustion engine.

[0023] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
