Description

Basement ventilation shaft

Technical Field

The utility model belongs to the technical field of the technique of building and specifically relates to a basement ventilation shaft is related to.

Background

At present, with the development of urbanization, the land resources are more and more tense. The utilization of underground space is a trend of urban modernization development, so that more and more basements are utilized. Because the basement is located below the ground and the ventilation performance is poor, the basement is generally provided with a ventilation shaft.

The existing ventilation shaft for the basement is provided with a well cover at the position of a well mouth, and meanwhile, a shutter is arranged on the side wall of the well shaft extending out of the ground, so that the ventilation in the basement can be enhanced through a chimney effect. In the utility model patent of the chinese utility model of grant bulletin No. CN207131043U, a basement daylighting ventilating shaft is disclosed, and the well lateral wall is cylindrical, installs rain-proof tripe on the lateral wall, and the clearance of the rain-proof tripe of accessible and outdoor ventilation are carried out.

The above prior art solutions have the following drawbacks: the basement closely realizes ventilating through the clearance of shutter, and the effect of ventilation is relatively poor.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a better basement ventilation shaft of ventilation effect. Its advantage lies in changing through the structure to the bottom of well lid, has played better guide effect to the air current that flows in or flow out, has improved the ventilation effect of basement air shaft.

The above utility model discloses an above-mentioned utility model purpose can realize through following technical scheme:

the utility model provides a basement ventilation shaft, includes the well body, install a plurality of support columns on the well body and be located the well lid at support column top, the slot has been seted up on the support column, install the well curb plate in the slot, a plurality of ventilation holes have been seted up to the well curb plate, the well curb plate is 30-60 contained angle with vertical direction, the well lid bottom is provided with the confession support column male jack, the well lid bottom is provided with the direction inclined plane that the guide air current flows.

Through adopting above-mentioned technical scheme, set up the slot on the support column for the well curb plate is pegged graft on the support column, has made things convenient for the dismantlement and the installation of well curb plate. Under the unchangeable condition of support column height, the well curb plate is 30-60 contained angles with vertical direction, compares with the perpendicular condition, has increased the area of contact of well curb plate with the external world, consequently can make more air in the external world flow into in the ventilation well. When the outside air current flows into the ventilation shaft or the air current in the ventilation shaft flows out of the outside, due to the existence of the guide inclined plane, the impact of the air current is reduced, the air current is prevented from returning to the original path after being impacted, a better guiding effect is achieved on the air current, and the ventilation effect of the ventilation shaft is better.

By adopting the technical scheme, because the direction of the wind direction is uncertain, the concave arc has better guiding effect on the airflow in each direction, so that most of the airflow flows into or out of the ventilating shaft, and the ventilating effect of the ventilating shaft is increased.

Preferably, the bottom of well lid is provided with the guide block, the direction inclined plane is located on the global of guide block, the top area of guide block is greater than the bottom area.

Through adopting above-mentioned technical scheme, because the thickness of well lid is thinner, it is limited that direct bottom at the well lid sets up the effect that the direction inclined plane can make the guide air current, consequently sets up the guide block bottom the well lid, again through setting up the direction inclined plane on the guide block. The top area of the guide block is larger than the bottom area, so that the guide effect on the airflow is better, and the best effect is that the bottom is reduced into a point, and the guide block is conical.

The top of guide block is provided with the connecting rod that runs through the well lid, the one end of connecting rod is provided with the mounting hole, mounting hole department is provided with the fixture block that runs through the mounting hole, the bottom of fixture block with the top looks butt of well lid.

Through adopting above-mentioned technical scheme, through the mode installation guide block of joint, can satisfy the functional requirement of guide block, it is more simple convenient again to install. Meanwhile, the guide block is connected in a clamping manner, so that the guide block is convenient to disassemble.

The fixture block is provided with a pull ring.

Through adopting above-mentioned technical scheme, when the fixture block joint was in the mounting hole, because the comparison of joint is inseparable, need just can extract the fixture block from the mounting hole with certain power, tightly through finger gripping fixture block, it is extremely inconvenient to extract the fixture block. The clamping block can be conveniently pulled out by directly pulling the pull ring through fingers by arranging the pull ring on one side of the clamping block, so that the operation is more convenient.

The cross section of the well side plate is a curved surface.

Through adopting above-mentioned technical scheme, the cross section of well curb plate is the curved surface for the surface area increase of well curb plate, consequently the well curb plate is bigger with external area of contact, and then can make more air current get into or flow out the ventilation shaft.

The ventilation holes are regular hexagonal holes.

By adopting the technical scheme, each angle of the regular hexagon is 120 degrees, so that the regular hexagon has the advantages of highest sealing degree, least required materials and largest usable space. Meanwhile, the side plates are provided with regular hexagonal holes, so that the side plates are strong in structural strength and not easy to damage. Not only meets the ventilation performance, but also enhances the strength of the side plate.

The top of the well lid is provided with a through hole communicated with the well way body, and an unpowered wind ball covering the through hole is installed at the through hole.

By adopting the technical scheme, the unpowered wind ball utilizes the natural air convection principle, combines the unique structural design of the wind ball, accelerates the air flow in any parallel direction and converts the air flow into the vertical air flow from bottom to top, and improves the ventilation effect in the underground chamber.

To sum up, the utility model discloses a beneficial technological effect does:

1. the contact area between the hoistway side plate and the outside is increased by changing the structure of the hoistway side plate, so that more wind enters the basement ventilation well through the ventilation holes; the guide inclined plane is additionally arranged at the bottom of the well cover, so that the inflow or outflow of airflow is better guided, and the ventilation effect in the ventilation well is better;
