Description

Technical Field

[0001] The utility model relates to the technical field of sound insulation, in particular to a sound insulation device for a hydraulic pump station. Background Art

[0002] A hydraulic pump is a device that converts mechanical energy into liquid pressure energy and is widely used in a variety of fields, including engineering machinery, manufacturing, automobiles, and aviation. A hydraulic pump uses a driver (such as an electric motor or diesel engine) to push a liquid (usually oil) to flow, providing power to the connected hydraulic system.

[0003] In existing technologies, sound insulation measures for hydraulic pump stations typically include wrapping the hydraulic pump with sound insulation material or isolating the hydraulic pump from the outside world with a soundproof cover. However, these measures have some shortcomings in actual use. First, the use of sound insulation materials will increase the weight and volume of the equipment, affecting its installation and maintenance. Second, although the soundproof cover can reduce noise, it is difficult to effectively reduce the structural noise caused by vibration. Since vibration noise is transmitted through the mechanical structure, a simple soundproof cover is difficult to completely isolate it; in addition, the existing sound insulation device is cumbersome during installation and disassembly, which is not conducive to daily maintenance and upkeep. These shortcomings limit the sound insulation effect and practicality of the hydraulic pump station in actual use. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and provide a sound insulation device for a hydraulic pump station.

A fitting plate 19 is provided at one end of the screw rod 18, and one end of the screw rod 18 is movably connected to the top side of the fitting plate 19. One side of the side panel 11 is fixedly connected to one end of the folding rod 111, and the inner surface of the folding rod 111 is slidably connected to one end of the side of the outer cover 110.

[0026] In this embodiment, when the sound insulation device of this type of hydraulic pump station is in use, in order to reduce the noise of the hydraulic pump during use, the hydraulic pump is installed between two bonding plates 19. Then, the screw 18 is rotated so that the bonding plates 19 and the hydraulic pump gradually approach each other until they are bonded and clamped. At this time, the hydraulic pump will be located in the frame plate 17. When the hydraulic pump is started, in order to isolate the noise caused by vibration, a sleeve 16 and a connecting rod 14 are provided on one side of the frame plate 17, and a rubber pad 15 is designed between the two. When vibrating, the connecting rod 14 will transfer the external force it receives to the cross bent plate 13, and the cross bent plate 13 will change its toughness in the cross groove 12, which can effectively absorb and buffer the energy generated by the vibration, prevent the structure from being damaged too much, and avoid the vibration from being directly transmitted to the surrounding environment, thereby reducing noise.
