Description

Technical Field

[0001] This utility model relates to the field of generator set technology, specifically a mobile low-noise generator set. Background Technology

[0002] A generator set is a power generation device that converts mechanical energy or other renewable energy sources into electrical energy. It is typically driven by a power system (such as a water turbine, steam turbine, or internal combustion engine) that converts various energy sources into electrical output. Generator sets are widely used in various fields, providing stable power support for people's production and daily life. In the field of generator set technology, the mobility and stability of the equipment have always been key considerations for designers.

[0003] Traditional generator set designs often face a dilemma: without rollers, while the stability of the unit during operation can be improved, moving and deployment become extremely inconvenient, especially when frequent changes of work location are required or in response to emergencies; on the other hand, with rollers, although movement is convenient, the stability of the unit's placement is often affected, especially on complex or uneven ground, which may cause vibration during operation, affecting power generation efficiency and equipment lifespan. To address these issues, the inventors have proposed a mobile, low-noise generator set to solve these problems. Utility Model Content

[0004] To address the issue of convenient movement of generator sets while ensuring stability during placement, the purpose of this invention is to provide a mobile, low-noise generator set.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a mobile low-noise generator set, including a base, with movable plates on both sides of the inner wall of the base, and casters rotatably connected to both sides of the bottom end of the movable plates. A transmission assembly is provided at the top of the inner wall of the base, and a force-multiplying assembly is provided between the transmission assembly and the movable plates. Two sets of the force-multiplying assemblies are provided and symmetrically arranged at the top of the movable plates. A soundproof box is fixedly connected to the top of the base, and the interior of the soundproof box is used to install the generator assembly.

[0006] Preferably, the transmission assembly includes a dual-axis motor, which is fixedly installed at the middle of the top of the inner wall of the base. Fixing plates are fixedly connected to the top of the inner wall of the base on both sides of the dual-axis motor. A threaded rod is fixedly connected to the drive end of the dual-axis motor. The end of the threaded rod away from the dual-axis motor is rotatably connected to the fixing plate. A movable block is threadedly connected to the outer side of the fixing plate. Two movable blocks are symmetrically distributed. Fixing rods are fixedly connected to both sides of each movable block. A connecting rod is rotatably connected to the end of each fixing rod away from the movable block.

[0007] Preferably, the force multiplier component includes a second connecting rod, which is rotatably connected to the top of the movable plate. A rotating rod is rotatably connected to the top of the inner wall of the base near the second connecting rod. The top of the second connecting rod is rotatably connected to the middle of the rotating rod, and the other end of the rotating rod is rotatably connected to the end of the first connecting rod away from the movable block.

[0008] Preferably, two guide rods are fixedly connected to both sides of the inner wall of the base, and two symmetrically distributed guide grooves are opened on the opposite side of the movable plate, and the guide grooves are slidably engaged with the outer side of the corresponding guide rods.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. The two threaded rods are driven to rotate in both directions by a dual-axis motor, which in turn drives the two moving blocks to move symmetrically to one side away from or towards the other. Under the connection of the first connecting rod, the caster can extend from the inside of the base or be stored inside the caster.

[0011] 2. During the extension process, when the caster moves to contact the ground, the second connecting rod, the rotating rod, and the caster form a lever mechanism. With the rotating rod and the rotation axis of the inner wall of the base as the fulcrum, the vertical distance from the connection point of the second connecting rod to the rotating rod to the fulcrum is less than the distance from the connection end of the first connecting rod to the rotating rod to the fulcrum. This amplifies the force on the second connecting rod, allowing the small force input by the dual-axis motor to generate a larger output force, thereby improving the efficiency and performance of the mechanical equipment.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Figure 1-3 As shown, this utility model provides a mobile low-noise generator set, including a base 1, with movable plates 2 on both sides of the inner wall of the base 1, and universal wheels 3 rotatably connected to both sides of the bottom end of the movable plates 2. A transmission component 4 is provided at the top of the inner wall of the base 1, and a force multiplier component 5 is provided between the transmission component 4 and the movable plates 2.

[0019] The transmission assembly 4 includes a dual-axis motor 41, which is fixedly installed at the middle of the top of the inner wall of the base 1. Fixing plates 42 are fixedly connected to the top of the inner wall of the base 1 and to both sides of the dual-axis motor 41. A threaded rod 43 is fixedly connected to the drive end of the dual-axis motor 41. The end of the threaded rod 43 away from the dual-axis motor 41 is rotatably connected to the fixing plate 42. A moving block 45 is threadedly connected to the outer side of the fixing plate 42. The two moving blocks 45 are symmetrically distributed. Fixing rods 46 are fixedly connected to both sides of the moving blocks 45. A connecting rod 44 is rotatably connected to the end of the fixing rod 46 away from the moving blocks 45.

[0020] By adopting the above technical solution, the two threaded rods 43 are driven to rotate in both directions by the dual-axis motor 41, and at the same time, the two moving blocks 45 are driven to move symmetrically to the side away from each other or to the side closer to each other. Under the connection of the connecting rod 44, the caster 3 can be extended from the inside of the base 1 or stored inside the caster 3.

[0021] The force multiplier assembly 5 includes a second connecting rod 51, which is rotatably connected to the top of the movable plate 2. A rotating rod 52 is rotatably connected to the top of the inner wall of the base 1 near the side of the second connecting rod 51. The top of the second connecting rod 51 is rotatably connected to the middle of the rotating rod 52, and the other end of the rotating rod 52 is rotatably connected to the end of the first connecting rod 44 away from the movable block 45.

[0022] By adopting the above technical solution, when the caster wheel 3 extends out of the base 1, the connecting rod 44 moves to one side of the rotating rod 52, and under the connection of the connecting rod 51, pushes the moving plate 2 and the caster wheel 3 downward. When the caster wheel 3 moves to contact the ground, the connecting rod 51, the rotating rod 52 and the caster wheel 3 form a lever mechanism. With the rotating shaft of the rotating rod 52 on the inner wall of the base 1 as the fulcrum, since the vertical distance between the connection point of the connecting rod 51 and the fulcrum is less than the distance between the connection end of the connecting rod 44 and the fulcrum, the force on the connecting rod 51 is amplified, so that the small force input by the dual-axis motor 41 can generate a large output force, thereby improving the efficiency and performance of the mechanical equipment.

[0023] Two guide rods 7 are fixedly connected to both sides of the inner wall of the base 1. Two guide grooves 8 are symmetrically distributed on the opposite side of the movable plate 2. The guide grooves 8 are slidably engaged with the outer side of the corresponding guide rods 7.

[0024] By adopting the above technical solution and setting the guide rod 7, the vertical movement of the moving plate 2 can be guided, thereby improving the stability of the moving plate 2 during vertical movement.

[0025] A soundproof box 6 is fixedly connected to the top of the base 1, and the interior of the soundproof box 6 is used to install the generator assembly.

[0026] By adopting the above technical solution, and by setting up a soundproof box 6, the generator set is installed inside the soundproof box 6, thereby isolating the noise generated when the generator is working.

[0027] Two sets of the power-multiplying components 5 are symmetrically arranged at the top of the movable plate 2.

[0028] By adopting the above technical solution and setting two sets of force-multiplying components 5, the stability of the force-multiplying components 5 when supporting the equipment can be improved.

[0029] Working principle: When the generator set needs to be moved, the dual-shaft motor 41 drives the two threaded rods 43 to rotate, which in turn drives the two moving blocks 45 to move symmetrically to one side away from each other. Under the connection of the first connecting rod 44, the rotating rod 52 is pushed to rotate downwards. Under the connection of the second connecting rod 51, the moving plate 2 and the universal wheel 3 are pushed to move downwards. When the universal wheel 3 moves to contact the ground, the second connecting rod 51, the rotating rod 52 and the universal wheel 3 form a lever mechanism. The rotating shaft of the rotating rod 52 and the inner wall of the base 1 is used as the fulcrum. Since the vertical distance from the connection point of the second connecting rod 51 and the rotating rod 52 to the fulcrum is less than the distance between the connection end of the first connecting rod 44 and the fulcrum of the rotating rod 52, the force on the second connecting rod 51 is amplified, so that the small force input by the dual-shaft motor 41 can generate a large output force, which can easily lift the device.

[0030] After the generator set is moved to a suitable position, the dual-shaft motor 41 rotates in the opposite direction. Similarly, the casters 3 are stored inside the base 1, thereby improving the stability of the equipment when it is placed.

[0031] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
