At present, a hinge cover-lifting type upper manhole is usually adopted for the manhole on the roof, but when the upper manhole is large, the weight of a cover plate is obviously increased, so that the cover plate is difficult to open and close in a climbing process by an operator.
For example, patent document CN207499262U discloses an upper manhole cover structure in a house structure;
CN103711264A discloses a cover plate device of an upper manhole, which comprises a pair of rails symmetrically arranged on the upper manhole; and a cover plate capable of sliding along the track; the track is formed by channel-section steel and angle steel welding, and the tip on two right-angle sides of angle steel is located the recess of channel-section steel, and the external corner of angle steel is kept away from the recess.
The upper manholes are all in cover plate type structures, and most of the upper manholes do not have the functions of natural ventilation and natural lighting up until now. For building rooms with poor lighting and ventilation, a mechanical ventilation system is mostly adopted, but most of the mechanical ventilation systems only have a single ventilation function and do not have a natural lighting function, and a large amount of electric energy is consumed in the operation process. Even if the natural ventilation system is started, the ventilation effect is still not ideal because the air flow organization is poor in the room. On the other hand, the lighting is mostly electric lighting, and a large amount of electric energy is consumed. Although some designs adopt natural light, most of the designs adopt transparent toughened glass, glare light is irradiated into the transparent toughened glass, condensation and glare can be formed, and an aperture can be formed indoors, so that the indoor environment and the ornamental value are influenced.
Therefore, it is necessary to improve the above drawbacks and invent a new manhole with natural lighting and natural ventilation functions.
