Abstract
The utility model discloses a kind of low-noise high-efficiency draught hood, comprise draught hood body, draught hood body is located at top, cabin, be communicated with cabin by people's hole, negative-pressure air fan is fixed on draught hood body side by fan supporter, negative blast machine outwards deflates, cover internal air pressure is declined, air weakens, form negative pressuren zone, air flows in cover, because other positions of draught hood body are sealing state because draught head compensates from the intake grill in cabin, air in cabin is Methodistic to be flowed into by intake grill, discharges through negative-pressure air fan.Any high heat, harmful gas, dust, smog all can discharge cabin rapidly, and ventilation thoroughly, efficiently, ventilation rate can reach 95%.
Description
Technical field
The utility model relates to ship's space, large-scale bin, the isostructural ventilation plant of tank body.
Background technique
In existing ship's space, workload is more, and ventilation condition is poor, and the general axial fan that adopts carries out ventilation, but axial fan noise is large, easily causes personnel tired; And guide duct is when entering cabin, take hole major part space, the inconvenience of personnel's inlet and outlet cave; For avoiding rainwater to invade, rainy day, the setting of ventilation duct was more difficult.
Summary of the invention
The utility model provides a kind of compact structure to solve deficiency of the prior art, manipulates the draught hood convenient, noise is low, ventilation volume is large, effectively improves construction environment.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of low-noise high-efficiency draught hood, comprise draught hood body, draught hood body is located at top, cabin, be communicated with cabin by people's hole, negative-pressure air fan is fixed on draught hood body side by fan supporter, negative blast machine outwards deflates, cover internal air pressure is declined, air weakens, form negative pressuren zone, air flows in cover, because other positions of draught hood body are sealing state because draught head compensates from the intake grill in cabin, air in cabin is Methodistic to be flowed into by intake grill, discharges through negative-pressure air fan.Any high heat, harmful gas, dust, smog all can discharge cabin rapidly, and ventilation thoroughly, efficiently, ventilation rate can reach 95%.
As a kind of preferred version of low-noise high-efficiency draught hood described in the utility model, described draught hood body bottom is fixed by base and top, cabin, draught hood body relies on the gravity of self to be supported on top, cabin by base, preferred base is made up of the rubber bar of filling in channel-section steel and channel-section steel, the seal of draught hood body can be improved on the one hand, rainwater can be avoided from outer side inflow cabin on the other hand, keep cabin inner drying.
As a kind of preferred version of low-noise high-efficiency draught hood described in the utility model, a side of described draught hood body is provided with normal closed gate.
As a kind of preferred version of low-noise high-efficiency draught hood described in the utility model, described ventilator cowling body, built with flameproof lamp, facilitates staff to carry out overhauling and operation.
Beneficial effect:
Low-noise high-efficiency draught hood described in the utility model, conveniently, convenient construction personnel pass in and out for compact structure, manipulation; Noise is low, effectively improves construction environment; Ventilation thoroughly, efficiently, ventilation rate can reach 95%; Avoid rainwater from outer side inflow cabin, keep cabin inner drying.

Wherein: 1, draught hood body 2, negative-pressure air fan 3, fan supporter 4, flameproof lamp 5, normal closed gate 6, lower storehouse handrail 7, people's hole 8, channel-section steel 9, rubber bar 10, cabin top board
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Embodiment 1
As shown in the figure, a kind of low-noise high-efficiency draught hood, comprise draught hood body 1, draught hood body 1 is located on cabin top board 10, is communicated with cabin by people's hole 7, and people's hole is other is also provided with lower storehouse handrail 6, negative-pressure air fan 2 is fixed on draught hood body 1 side by fan supporter 3, be provided with normal closed gate 5 in the other side of draught hood body, draught hood body bottom is the sealed base formed by the rubber bar 9 in channel-section steel 8 and channel-section steel, and rubber bar effectively prevents rainwater from the inflow in outside.Inside draught hood body 1, flameproof lamp 4 is located on top, and convenient construction personnel carry out operation.
Although be illustrated mode of execution of the present utility model in specification, these mode of executions just as prompting, should not limit protection domain of the present utility model.In the scope not departing from the utility model aim, carry out various omission, displacement and change all should be included in protection domain of the present utility model.
