Abstract
The utility model discloses a venting opening structure for a municipal common ditch. An exhaust fan in a venting opening is internally arranged in a channel of the portion of the venting opening under the ground, and the size of the venting opening exposed out of the ground just meets requirements for exhaust air rate without taking the size of the exhaust fan into consideration. The technical scheme is that the venting opening structure for the municipal common ditch comprises a venting channel and fan, the venting channel is composed of an overground portion and an underground portion and is communicated with the municipal common ditch, the venting opening is arranged at the overground portion of the venting channel, and the fan is positioned at the underground portion. The exhaust fan is concealed underground so as to reduce running noise and be not prone to be stolen. Only a rainproof shutter air port is arranged on the ground so as to enable a road to be concise.
Description
Technical field
The utility model discloses a kind of ventilating opening structure that is used for municipal common trench, divides by International Patent Classification (IPC) (IPC) to belong to municipal engineering technology for making field.
Background technology
Present municipal common trench generally all adopts the external ventilation opening on the road surface of a plurality of blower fans; Solved the demand of municipal common trench ventilation smoke exhaust; Yet the ventilation opening of this common structure has following drawback: (1), the exhaust blower above the ventilation opening expose to the open air outdoor stolen or aging easily; (2), exhaust blower noise when moving at ordinary times is bigger, has influence on the normal life of its surrounding resident; (3), the big road landscape that influences of floor space.
Summary of the invention
Deficiency to prior art; The utility model provides a kind of safe ventilating opening structure that is used for municipal common trench rational in infrastructure, practical; Not only can solve the demand of municipal common trench ventilation smoke exhaust, also solve the problem of aspects such as ventilation opening is big, exhaust blower is hidden simultaneously.
For achieving the above object, the utility model is realized through following technical scheme:
A kind of ventilating opening structure that is used for municipal common trench; Comprise ventilation stack and blower fan; Described ventilation stack partly is made up of overground part and below ground and is communicated with municipal common trench, and ventilation stack is positioned at overground part and has ventilation opening, and the ventilation stack that locates below ground level is provided with blower fan.
Further, protective cover is arranged at the top that ground is said in described ventilation, and this protective cover below is provided with stormproof louvre and forms ventilation opening, and concrete installation dimension can be confirmed according to landscape design.
Further, described municipal common trench top is provided with removable cover and forms the charging access hole.
Further, described blower fan is an axial flow blower, and it is positioned at the ventilation stack of ventilation opening in the below ground part, and there is flameproof enclosure in axial flow blower week, and this flameproof enclosure is that stainless steel style plate constitutes.
The utility model is to be built into ventilation opening to the exhaust blower in the ventilation opening in the passage of below ground part, makes ventilation opening go out the requirement that size behind the ground only need satisfy exhaust air rate and gets final product, and need not to consider the size of exhaust blower.So just can make exhaust blower be hidden in underground, thereby reduce the noise when moving and be not easy stolen.Go out ground and the stormproof louvre air port only need be set get final product, can make road landscape more succinct like this.
Description of drawings
Fig. 1 is the utility model ventilation opening and charging access hole plan view;
Fig. 2 is an A-A sectional drawing among Fig. 1;
Fig. 3 is a B-B sectional drawing among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Embodiment: see also Fig. 1 to Fig. 3; A kind of ventilating opening structure that is used for municipal common trench; Comprise ventilation stack 1 and blower fan 2; Described ventilation stack partly is made up of overground part and below ground and is communicated with municipal common trench, and ventilation stack is positioned at overground part and has ventilation opening 3, and the ventilation stack that locates below ground level is provided with blower fan 2.The top, ground is said in ventilation has protective cover 4, and this protective cover below is provided with stormproof louvre 5 and forms ventilation opening, and concrete installation dimension can be confirmed according to landscape design.Described municipal common trench top is provided with removable cover 6 and forms the charging access hole.Described blower fan 2 is an axial flow blower, and it is positioned at the ventilation stack of ventilation opening in the below ground part, and there is flameproof enclosure 7 in axial flow blower week, and this flameproof enclosure is that stainless steel style plate constitutes, and establishes stainless steel style plate at the hole.
The above record is merely the embodiment that utilizes this origination techniques content, anyly is familiar with modification, the variation that this creation of this art utilization is done, and all belongs to the claim of this creation opinion, and is not limited to embodiment announcement person.
