Description

Technical Field

[0001] The utility model relates to the technical field of building ventilation structures, in particular to a novel ground vent. Background Art

[0002] Ventilation holes are an important part of underground structures such as underground spaces, tunnels, pipe galleries, and underground garages. The ventilation, heat removal, and moisture removal of underground structures all require air convection between ground vents and the air above ground. With the continuous development of underground spaces, the number of ground vents has also increased.

[0003] Most of the existing ground vents are louvered vents set on the side of the ground air shaft for ventilation. The number of louvered vents is very limited. In order to ensure that sufficient air volume enters the air shaft and then ensure sufficient ventilation effect inside the air shaft, the louver area is often required to be larger, which leads to larger size and higher height of the ground vents, thus affecting the field of vision and landscape effect.

[0004] Therefore, how to increase the ventilation volume in the air shaft without increasing the size of the air shaft above the ground has become a technical problem that technical personnel in this field urgently need to solve. Utility Model Content

[0005] In view of the above-mentioned defects of the prior art, the utility model provides a new type of ground vent, the purpose of which is to ensure the ventilation volume of the wind shaft and reduce the impact on the field of vision and landscape effect without increasing the size of the vent out of the ground.

[0006] In order to achieve the above technical purpose, the utility model provides a new type of ground vent, including a wind shaft cover plate arranged on the top of the wind shaft, the top of the wind shaft is flush with the ground, a plurality of ventilation holes are arranged on the wind shaft cover plate at intervals, and a wind shield is respectively arranged on the wind shaft cover plate at a position corresponding to each of the ventilation holes;

[0007] At least one rainproof shutter is arranged on the side of each wind shield.

[0008] Preferably, when the cross-section of the wind shield is polygonal, the rainproof louvers are respectively arranged on one or more vertical sides of the wind shield.

[0009] Preferably, when the cross-section of the wind shield is circular, the rainproof louvers are arranged on the vertical side surfaces of the wind shield along the circumferential direction.

[0010] Preferably, there is a spacing distance between the bottom of the rainproof louver and the bottom of the wind shield.

[0011] Preferably, the number of the ventilation holes is not less than two, and the plurality of ventilation holes are arranged at equal intervals.

[0012] Beneficial effects of the utility model:

[0013] Due to the above-mentioned structural design, the utility model utilizes multiple rainproof louvers in conjunction with ventilation holes opened on the wind shaft cover that do not protrude from the ground for ventilation, thereby ensuring the ventilation volume of the wind shaft and greatly reducing the size of the vents of the wind shaft out of the ground, further reducing the impact on the field of vision and improving the landscape effect.

[0017] The concept, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings to fully understand the purpose, characteristics and effects of the present invention.

[0018] Example:

[0019] like Figure 1-Figure 2 As shown, the novel ground vent includes a wind shaft cover plate 2 arranged on the top of the wind shaft 1, the top of the wind shaft 1 is flush with the ground, a plurality of ventilation holes 3 are arranged at intervals on the wind shaft cover plate 2, and a wind shield 4 is respectively arranged on the wind shaft cover plate 2 corresponding to each ventilation hole 3;

[0020] In this embodiment, rainproof shutters 5 are respectively arranged on both sides of each wind shield 4 .

[0021] In other embodiments, when the cross section of the wind shield 4 is polygonal, the rainproof louvers 5 are respectively arranged on one or more vertical sides of the wind shield 4 .

[0022] In other embodiments, when the cross section of the wind shield 4 is circular, the rainproof louvers 5 are arranged on the vertical side surfaces of the wind shield 4 along the circumferential direction.

[0023] The main innovation of the utility model is that a plurality of rainproof louvers 5 are used in conjunction with ventilation holes 3 that do not protrude from the ground for ventilation, thereby ensuring the ventilation volume of the air shaft 1, reducing the impact on the field of vision, and improving the landscape effect.

[0024] In this embodiment, the number of ventilation holes 3 is not less than 2, and specifically 5 ventilation holes 3 are arranged at equal intervals. The ventilation holes 3 are arranged at intervals, and the corresponding wind hoods 4 are also spaced a certain distance apart, thereby facilitating side ventilation.

[0025] More specifically, the wind hood 4 is installed above the wind shaft cover 2, which can be easily disassembled, repaired and replaced.

[0026] Furthermore, when the underground structure needs to be ventilated, the air flow can pass through the rainproof louvers 4 on the side of the wind hood 4 to achieve a ventilation effect; in order to prevent rainwater from entering the air shaft 1 through the waterproof louvers 5, there is a spacing distance between the bottom of the rainproof louvers 5 and the bottom of the wind hood 4.

[0027] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
