Technical Field
[0001] This utility model relates to the field of diesel generator technology, and in particular to a marine diesel generator set. Background Technology
[0002] Marine diesel generator sets are a type of power and electrical supply equipment widely used on ships. They mainly use diesel engines to drive generators, thereby providing stable power support for the ship's navigation, communication, lighting, and various electromechanical equipment. These devices typically feature compact structures, stable output power, and adaptability to the marine environment. They can meet the power needs of ships under various operating conditions, such as ocean voyages and port operations, and are one of the important pieces of equipment to ensure the normal operation of ships.
[0003] In existing technologies, the vibrations generated by the generator set during operation are directly transmitted to the installation location and the hull. The vibrations cannot be effectively weakened, which leads to a decrease in the stability of the generator set itself and problems such as loosening of components and accelerated wear. Utility Model Content
[0004] Given that the vibrations generated by existing generator sets during operation are directly transmitted to the installation location and the hull, and the vibrations cannot be effectively weakened, the generator set itself becomes less stable and is prone to problems such as loosening of components and increased wear, this utility model is proposed.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a marine diesel generator set, including a support structure, an installation structure, a generator set, and a protective structure. The installation structure is installed on the support structure, and the generator set and the protective structure are respectively installed on the installation structure. The installation structure includes a base plate, a rubber pad, a hydraulic cylinder, a hydraulic rod, and a spring. The rubber pad is fixedly attached to the top of the base plate. The base plate and the rubber pad are symmetrically provided with installation grooves. The base plate and the rubber pad are respectively provided with first installation holes at the four corners. The hydraulic rod is respectively fixedly installed with a piston and a support plate. The piston is provided with a flow hole. The support plate and the bottom wall of the base plate are fixedly connected. The spring is sleeved on the hydraulic cylinder. The bottom of the generator set is provided with a fixing hole that matches the installation groove.
[0006] In a preferred embodiment of the marine diesel generator set of this utility model, the support structure includes a base and lugs, with the lugs fixedly installed at both ends of the base.
[0007] In a preferred embodiment of the marine diesel generator set of this utility model, the base plate is disposed at the top of the base, and the hydraulic cylinder is fixedly installed at the four corners of the top of the base.
[0008] In a preferred embodiment of the marine diesel generator set of this utility model, the hydraulic rod is slidably disposed inside the hydraulic cylinder, the piston is fixedly installed at the bottom end of the hydraulic rod, the piston and the inner wall of the hydraulic cylinder are slidably connected, and the support plate is fixedly installed at the top end of the hydraulic rod.
[0009] In a preferred embodiment of the marine diesel generator set of this utility model, the top end of the spring is fixedly connected to the support plate, and its bottom end is fixedly connected to the base.
[0010] As a preferred embodiment of the marine diesel generator set of this utility model, the protective structure includes a protective cover and a mounting plate. The mounting plate is fixedly installed on the outer bottom wall of the protective cover, and the four corners of the mounting plate are provided with second mounting holes that are adapted to the first mounting holes.
[0011] As a preferred embodiment of the marine diesel generator set of this utility model, heat dissipation grooves are respectively provided on both sides of the protective cover, and the front and rear of the protective cover are respectively hinged to the switch door. A layer of sound-absorbing cotton is attached to the inner wall of the protective cover and the switch door, and a handle is fixedly installed on the switch door.
[0012] The beneficial effects of this utility model are: 1. Through the set installation structure, the vibration of the generator set is initially buffered by the rubber pad. Then, the hydraulic oil in the hydraulic cylinder is used to limit the flow through the piston flow hole. Combined with the elastic extension and contraction of the spring, a multi-stage vibration reduction structure is formed, which can effectively slow down the piston movement speed, weaken the vibration transmission, ensure the stability of the generator set installation, reduce the impact of vibration on itself and the ship, and improve the stability and service life of the equipment. 2. Through the designed protective structure, the protective cover effectively protects the generator set. The sound-absorbing cotton on the inner wall can absorb some of the working noise and reduce noise pollution. The heat dissipation slots can dissipate the heat generated by the unit in a timely manner to ensure its normal operation. The opening and closing door design makes it convenient for staff to open it for maintenance at any time. Overall, it takes into account protection, noise reduction, heat dissipation and maintenance convenience, and improves the safety and practicality of the equipment. Attached Figure Description

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0016] Example 1 Refer to attached figure Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 The first embodiment of this utility model provides a marine diesel generator set, including a support structure 1, an installation structure 2, a generator set 3, and a protective structure 4. The installation structure 2 is installed on the support structure 1, and the generator set 3 and the protective structure 4 are respectively installed on the installation structure 2. The support structure 1 includes a base 11 and lugs 12. The lugs 12 are fixedly installed at both ends of the base 11, and the base 11 is installed on the bottom wall of the ship through the lugs 12.
[0017] Mounting structure 2 includes a base plate 21, a rubber pad 22, a hydraulic cylinder 25, a hydraulic rod 26, and a spring 28. The base plate 21 is located at the top of the base 11. The rubber pad 22 is fixedly attached to the top of the base plate 21. Mounting grooves 23 are symmetrically arranged on the base plate 21 and the rubber pad 22. First mounting holes 24 are respectively provided at the four corners of the base plate 21 and the rubber pad 22. The hydraulic cylinder 25 is fixedly installed at the four corners of the top of the base 11. The hydraulic cylinder 25 is filled with hydraulic oil. The hydraulic rod 26 is slidably mounted. Inside the hydraulic cylinder 25, a piston 29 is fixedly installed at the bottom end of the hydraulic rod 26. The piston 29 is slidably connected to the inner wall of the hydraulic cylinder 25. A flow hole is provided on the piston 29. A support plate 27 is fixedly installed at the top end of the hydraulic rod 26. The support plate 27 is fixedly connected to the bottom wall of the base plate 21. A spring 28 is sleeved on the hydraulic cylinder 25. The top end of the spring 28 is fixedly connected to the support plate 27, and its bottom end is fixedly connected to the base 11. The bottom of the generator set 3 is provided with a fixing hole that matches the mounting groove 23.
[0018] During use, the base 11 is fixedly installed on the bottom wall of the ship by the lug 12. Then, the generator set 3 is placed on the rubber pad 22, and the fixing hole and the mounting groove 23 are aligned. Then, it is fixed by bolts, so that the generator set 3 is fixedly installed on the rubber pad 22. When the generator set 3 is used, the generator set 3 will vibrate. The vibration generated by the generator set 3 is transmitted to the support plate 27 through the rubber pad 22 and the base plate 21, so that the support plate 27 vibrates. The support plate 27 drives the piston 29 to move in the hydraulic cylinder 25 through the hydraulic rod 26, while pressing or stretching the spring 28. When the piston 29 moves, because the hydraulic oil is incompressible, the hydraulic oil flows from the flow hole, thereby preventing the piston 29 from sliding too fast, realizing the vibration reduction effect and improving the stability of the generator set 3.
[0019] Example 2 Refer to attached figure Figure 1 and attached Figure 6 This is the second embodiment of the present invention, which differs from the first embodiment in that: The protective structure 4 includes a protective cover 41 and a mounting plate 42. The mounting plate 42 is fixedly installed on the outer bottom wall of the protective cover 41. The four corners of the mounting plate 42 are provided with second mounting holes 43 that are compatible with the first mounting holes 24. Heat dissipation grooves 44 are provided on both sides of the protective cover 41. Switch doors 45 are hinged to the front and back of the protective cover 41 respectively. A layer of sound-absorbing cotton is attached to the inner wall of the protective cover 41 and the switch door 45. A handle is fixedly installed on the switch door 45.
[0020] During use, the protective cover 41 covers the generator set 3 and aligns the second mounting hole 43 with the first mounting hole 24. Then, it is fixed with bolts. The protective cover 41 provides a certain degree of protection for the generator set 3. When the generator set 3 is working, part of the sound generated is absorbed by the sound-absorbing cotton, thereby reducing the noise generated by the generator set 3. At the same time, by setting the heat dissipation groove 44, the heat generated by the generator set 3 can be dissipated to the external environment. The switch door 45 is opened by the handle, which makes it convenient for the staff to inspect and maintain the generator set 3.
[0021] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
