The conventional design is to add a ventilation bar to the cabin door to connect the cabin and the corridor. But have high syllable-dividing requirement between cabin and the corridor on passenger ship, conventional air fence sets up on preventing fire door, and sound insulation effect is not good, can't satisfy high sound insulation requirement.
SUMMERY OF THE UTILITY MODEL
The application provides a high syllable-dividing ventilation chassis of passenger ship sanitary unit, the current ventilation bars's of its aim at design can't satisfy between cabin and the corridor high syllable-dividing requirement.
In order to achieve the technical purpose, the following technical scheme is adopted in the application:
high syllable-dividing ventilation chassis of passenger ship sanitary unit, it sets up in cabin bathroom below for the intercommunication cabin and corridor, the high syllable-dividing ventilation chassis of passenger ship sanitary unit includes: the chassis frame is of a frame structure with a hollow interior and sealed peripheral walls, and an air inlet and an air outlet are formed in the chassis frame; a floor drain is arranged on the top plate of the chassis frame, a drain outlet is arranged on the bottom plate of the chassis frame, and the floor drain and the drain outlet are connected through a drain pipe; the noise blocking partitions are respectively welded inside the chassis frame, and enable an air channel path from an air inlet to an air outlet in the chassis frame to be a nonlinear air channel; the sound-absorbing rock wool is laid on each sound-blocking partition; a plurality of shock-absorbing steel plates fixed on the upper surface of the bottom plate of the chassis frame through damping materials; the return air inlet grille is fixed at the air inlet; and the return air outlet grille is fixed at the air outlet and is connected with the corridor wallboard through a fixing piece.
Preferably, a plurality of reinforcing ribs are arranged in the chassis frame, and each reinforcing rib is vertically connected with the sound blocking partition.
Preferably, the drain pipe is sloped.
Preferably, the non-linear air duct is an S-shaped air duct.
Preferably, the return air outlet grille is connected to the air outlet in a sealing manner through glue.
Owing to adopt above-mentioned technical scheme, the high syllable-dividing ventilation chassis of passenger ship sanitary unit of this application has realized the return air in passenger cabin and corridor to set up the passageway of amortization in the chassis, realize high syllable-dividing effect.
Drawings
FIG. 1 is a schematic view of the present application in use;
FIG. 2 is a cross-sectional view of an embodiment of the present application;
FIG. 3 is a sectional view taken along the line A;
fig. 4 is a cross-sectional view taken along direction B.
Detailed Description
The technical scheme of the utility model is further specifically described by the following embodiments and the accompanying drawings.
Referring to fig. 1, unlike the prior art that a ventilation bar is added to a cabin door, the present application provides a ventilation device under a toilet in a cabin and communicates the cabin with a corridor.
Referring to fig. 2 to 4, the high-sound-insulation ventilation chassis D for the passenger ship sanitary unit includes a chassis frame 1, a sound-blocking partition 2, sound-absorbing rock wool 3, and a shock-absorbing steel plate 4.
The chassis frame 1 is a frame structure with a hollow interior and sealed peripheral walls. The shape of the chassis frame is not fixed and can be determined according to the space from the toilet to the corridor in each passenger cabin. The chassis frame 1 is provided with an air inlet 11 and an air outlet 12. The top plate of the chassis frame 1 is provided with a floor drain 5, the bottom plate of the chassis frame 1 is provided with a water outlet 6, and the floor drain 5 and the water outlet 6 are connected through a water outlet pipe 7.
The top plate of the chassis frame 1 is welded directly to the chassis frame. The components of the toilet can be arranged on the chassis frame 1 with the top plate of the chassis frame 1 as the bottom. Set up in the bathroom below, can practice thrift the utilization in space, use the bottom of bathroom as the space of amortization, the position of return air is located the below, can not cause indoor wind-force to change obviously because of the circulation of air.
A plurality of sound blocking partitions 2 are respectively welded on a bottom plate of the chassis frame 1, 4 sound blocking partitions 2 are shown in the embodiment, and as shown in fig. 2, the 4 sound blocking partitions 2 block an air duct from an air inlet to an air outlet to form an S-shaped non-linear air duct. The S-shaped non-linear air duct can obstruct sound from being transmitted linearly, and plays a role in sound insulation. In addition, the sound-absorbing rock wool 3 is laid on each sound-blocking partition 2, so that sound absorption and noise reduction are further achieved. In addition, a layer of damping steel plate 4 is paved on the upper surface of the bottom plate of the chassis frame by damping materials, and the resonance frequency is changed by the damping steel plate 4, so that the noise generated by vibration is reduced.
The return air inlet grille 8 is fixed at the air inlet of the chassis frame 1 through glue, and the size of the opening can meet the return air volume requirements of different cabins. The return air outlet grille 9, the chassis frame 1 air outlet is connected with the wallboard and sealed by using a sealant, and is connected with the corridor wallboard through a screw, and the size of the opening of the accessible meets the requirements of return air volume of different cabins.
A plurality of reinforcing ribs 10 are arranged in the chassis frame, and each reinforcing rib 10 is vertically connected with the sound blocking partition 2 so as to increase the arranging strength.
The high syllable-dividing ventilation chassis of passenger ship sanitary unit in this application can satisfy the return air requirement and can satisfy the high syllable-dividing requirement between cabin and the corridor again.
The above-described embodiments are merely illustrative of the present invention and are not intended to limit the scope of the present invention. All equivalent changes and modifications of the utility model that may occur to those skilled in the art are intended to be covered by the appended claims.
