Description

Technical Field

[0001] The utility model relates to the field of shock-absorbing and noise-reducing devices, in particular to a shock-absorbing and noise-reducing device for a water intake pump used for a pontoon. Background Art

[0002] As we all know, a pontoon is a rectangular flat-bottomed boat without a power device, fixed on the shore or dock for ships to dock, board and disembark passengers, and load and unload cargo. A pontoon water pump is a water pump body used on a pontoon, which can extract river water or sea water. Most of the pontoon water pumps currently on the market will generate strong vibration noise when in use. The vibration will drive the connected inlet and outlet pipes to generate vibration noise synchronously, causing the hull structure to be in a fatigue state. If it continues, cracks or fatigue damage will appear in the high stress area of ​​the hull structure, shortening the service life of the ship.

[0003] In response to the above problems, a shock-absorbing and noise-reducing device for a water intake pump for a pontoon with Chinese patent publication number CN220726688U can effectively eliminate the vibration when the vibration generated by the water intake pump reaches the first hose and the second hose under the buffering effect of the soft connection of the first hose and the second hose itself, so that the vibration is no longer transmitted along the water inlet pipe and the water outlet pipe, thereby effectively eliminating the resonance of the connection and reducing the transmission of vibration, thereby simultaneously reducing noise and avoiding damage to the hull structure and instruments on the hull.

[0004] Although the comparative patent solves the problem that the water intake pump will generate strong vibration noise when in use, and the vibration will drive the water inlet pipe and water outlet pipe connected to it to generate vibration noise synchronously, causing the hull structure to be in a fatigue state, but the device cannot reduce the shock and noise of the water intake pump itself. Since the inner wall of the water intake pump will generate a large noise when working, its body will generate a strong vibration, which greatly reduces the shock absorption effect and reduces the noise reduction effect.

[0005] With respect to the above-mentioned related technologies, the device has the defect that it cannot reduce the vibration and noise of the water intake pump itself, which greatly reduces the vibration reduction effect and the noise reduction effect. Utility Model Content
