Description

Technical Field

[0001] The utility model relates to a water intake pump ship, in particular to a modular water intake pump ship for preventing resonance. Background Art

[0002] During the operation of the water intake pump ship, multiple pump sets are usually configured according to the power requirement. When multiple pump sets operate simultaneously, the vibrations of the pump sets will be superimposed or resonate, which has a greater impact on the structure and noise of the hull and is not conducive to the safe and stable operation of the pump ship. Summary of the Invention

[0003] The utility model provides a modular water intake pump ship for preventing resonance, which has a simple structure and can effectively eliminate the vibration superposition and resonance of multiple pump sets.

[0004] The technical solution adopted by the utility model is: a modular water intake pump ship for preventing resonance, including multiple pump sets, characterized in that: each of the multiple pump sets is separately configured with a supporting hull module, and adjacent two supporting hull modules are connected by more than two soft cables from top to bottom. The upper end faces of adjacent two supporting hull modules jointly support a movable connecting plate. Two connecting long grooves along the direction of the movable connecting plate are respectively opened at both ends of the movable connecting plate. A connecting bolt is vertically connected to the upper end faces of adjacent two supporting hull modules, and the connecting bolt passes through the connecting long groove.

[0005] A modular water intake pump ship for preventing resonance, including multiple pump sets, characterized in that: each of the multiple pump sets is separately configured with a supporting hull module, and adjacent two supporting hull modules are connected by more than two soft cables from top to bottom. Along the direction perpendicular to the two supporting hull modules, the upper end faces of adjacent two supporting hull modules jointly support more than two movable connecting plates. Two connecting long grooves along the direction of the movable connecting plate are respectively opened at both ends of the movable connecting plate. A connecting bolt is vertically connected to the upper end faces of adjacent two supporting hull modules, and the connecting bolt passes through the connecting long groove.

[0006] The soft cable is a steel soft cable.

[0007] The steel soft cable is a steel chain.

[0008] A tightening steel sleeve with a length less than the gap between adjacent two supporting hull modules is sleeved outside the steel soft cable.

[0009] A cover for covering the connecting bolt is provided on the movable connecting plate. The inner top wall of the cover is higher than the connecting bolt, and the cover is fixedly connected to the movable connecting plate.

[0010] A connecting flange is arranged on the lower flanging side of the cover, and the connecting flange is locked and connected to the movable connecting plate by screws.

[0011] The beneficial effects of the utility model are:

[0012] 1. A separate supporting hull module is used to support each pump group respectively, avoiding the vibration superposition or resonance of multiple pump groups on the same hull.

[0013] 2. The adjacent supporting hull modules are connected by soft cables. The movable connecting plate is movably connected to the connecting bolts on the supporting hull module through the connecting long slots. On the basis of ensuring the overall connection stability, there is no rigid connection between adjacent supporting hull modules, effectively avoiding vibration transmission and further improving its anti-vibration performance.

[0014] 3. The cover is used to cover the connecting bolts, which can restrain them when there is a height difference between adjacent supporting hull modules, preventing the connecting bolts from slipping out of the connecting long slots and further improving the connection stability. Combining with the outer sleeve of the steel soft cable pressing against the steel sleeve, on the basis of ensuring soft connection, the distance between the lower parts of adjacent supporting hull modules is effectively limited to prevent collision and further improve the connection stability.
