Abstract
The utility model belongs to the technical field of shock absorption and noise treatment, in particular to the technical field of the water cushion shock absorption of a diesel generator unit. The diesel generator unit 1 is arranged above an anti-shock cushion 3 in a pontoon 2, and is positioned at the position of a limit block 4 in the pontoon; the pontoon 2 is arranged above an anti-shock cushion 5 outside the pontoon in a cement pit 7, and is positioned at the position of the limit block 6 outside the pontoon; and medium water 8 is fully filled in the cement pit 7 outside the pontoon 2. The technology solves and overcomes the defects that the solid sound transmission noise treatment means in the noise treatment of the diesel generator unit are not many and good enough. Particularly the treatment means of the solid sound transmission noise of a diesel generator room of an integral building is nearly blank. The technology can reduce and impede the solid sound transmission of the unit to a foundation, particularly greatly improves the solid sound transmission noise treatment effect of the diesel generator unit to the integral building.
Description
Technical field:
The utility model belongs to damping noise management technique field, particularly diesel generating set water cushion cushion technique field.
Background technology:
It mainly is the processing of handling the air-borne sound borne noise that the noise of diesel motor set of prior art is handled, and places restrictions on the noise that air-borne sound is propagated as means such as sound insulation, sound absorption, noise elimination, dampings.And how not good enoughly owe for the processing means of solid-borne noise borne noise.Especially it is the solid-borne noise borne noise of the diesel generation machine room in Even body building, and the processing means are close to blank.
The diesel generating set of prior art is handled for the solid-borne noise borne noise, and just additional mass is got on sound bearing medium.For example require the installation basis of 500kW diesel generating set to be the concrete of 6m * 3.6m * 1.8m in " the 500kW diesel generating set operation instructions " of Ningbo engine factory; And for example the installation foundation drawing of the 1000kW diesel generating set of Ningbo engine factory is the concrete of 8.5m * 4.5m * 2.1m.The solid-borne noise borne noise of the diesel generation machine room in its real Even body building, above-mentioned treatment effect is very little.
The equipment earthquake-proof foundation technology of prior art is ZL200620045915.5 as the patent No., and patent name is a kind of shockproof locked instrument of equipment that is used for the clean room, also is to belong to the additional mass block type.
Summary of the invention:
In order to overcome the shortcoming of background technology, the utility model purpose provides a kind of brand-new diesel generating set water cushion cushion technique, promptly on the solid-borne sound transmission medium, add multiple mass, make sound bearing medium be inhomogeneities, thereby generation sound reflecting of solid-borne noise communication process and sound barrier reduce and the obstruction solid-borne noise is propagated.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of diesel generating set water cushion cushion technique is characterized in that diesel generating set, place on the interior crash roll of case in the buoyancy tank, and be positioned the position of case inner limited block, buoyancy tank places on the outer crash roll of the case in the cement pit, and being positioned the case position of guide vane end stop outward, buoyancy tank has been full of WATER AS FLOW MEDIUM within the cement pit.
The beneficial effects of the utility model are: a kind of diesel generating set water cushion damping of technique scheme.Reached the utility model purpose, realized having the effect that reduces significantly and hinder the solid-borne noise propagation,, the solid-borne noise noise processed has been made a major contribution for handling well in whole diesel generation machine room air-borne sound and the solid-borne noise noise.
Description of drawings:
Fig. 1 is that schematic illustration is implemented in the damping of the utility model diesel generating set water cushion substantially.
Be illustrated as:
2 casees interior 3 casees inner limited blocks of crash roll 4 of diesel generating set 1 buoyancy tank
5 casees outer guide vane end stop 6 cement pits 7 WATER AS FLOW MEDIUM 8 of the outer crash roll of case
Embodiment:
Below the enforcement schematic illustration of the utility model accompanying drawing is described in further detail:
A kind of diesel generating set water cushion cushion technique as shown in Figure 1, it is characterized in that diesel generating set 1 places in the case in the buoyancy tank 2 on the crash roll 3, and be positioned the position of case inner limited block 4, buoyancy tank 2 places on the outer crash roll 5 of the case in the cement pit 7, and being positioned the case position of guide vane end stop 6 outward, buoyancy tank 2 has been full of WATER AS FLOW MEDIUM 8 within the cement pit 7.
Described WATER AS FLOW MEDIUM 8, its water surface site should be able to be regulated and control and fix.Because diesel generating set is in power generation process, the moment of generator amature cutting magnetic line and countertorque need a part of gravity of unit to keep the stable of buoyancy tank 2.
So the utility model diesel generating set water cushion cushion technique has only been realized minimizing and has been hindered the solid-borne noise propagation of unit to ground., still need and deal carefully with in addition all around air-borne sound and the solid sonic propagation up and down of generating set machine room for unit and blast pipe, air inlet pipe, water inlet pipe, outlet pipe etc.
