The invention will be described in detail with reference to the following embodiments with reference to the attached drawings.
An outdoor windproof structure of a fresh air fan pipeline is shown in figures 1 to 3 and comprises a hood arranged at an outdoor end pipe orifice 1 of the fresh air fan pipeline and a windproof seat sleeved at the outdoor end pipe orifice;
the wind cap comprises an inner wind cap body 2 and an outer wind cap body 3, the inner wind cap body and the outer wind cap body are coaxially arranged, and the inner wind cap body and the outer wind cap body are connected through a support plate 4; the supporting plate is vertical to the axial direction of the inner wind cap body; in the invention, the supporting plate is of a closed plate-shaped structure.
The inner wind cap body comprises an end cap 5 and a wind-proof ring 6 at the rear end of the end cap, and a fixing ring 7 is arranged on the inner side of the wind-proof ring; the windproof ring is connected with the fixed ring through a windproof plate 8, and a plurality of wind passing holes are formed in the windproof plate; the conical end of the outer hood body is provided with an opening 9;
in an optional embodiment, one side of the windproof ring facing the windproof seat is provided with a first windproof bending part 10 which is turned to the side different from the windproof seat; the wind-proof seat is provided with a second wind-proof bent part 11 which is turned to one side different from the wind-proof ring and faces one side of the wind-proof ring; an air passing channel 12 is formed between the first wind-proof bent part and the second wind-proof bent part. Such structural design has guaranteed that even there is some air current to turn back to the hood inboard along the wall, also can receive the stopping of preventing wind kink, and furthest avoids blowing into in the mouth of pipe, and the air of following the mouth of pipe exhaust can smoothly discharge, does not receive any influence.
The fixing ring is fixed on the pipe orifice part at the outdoor end of the fresh air fan pipeline through gluing or a connecting piece. Typically, the connection is by screws or ferrules.
In an optional embodiment, the end cap is in a conical cylindrical structure, the outer side of the end cap is a closed end, and the inner side of the end cap is opened towards the pipe orifice at the outdoor end of the fresh air fan pipeline, so that the possibility that wind blows into the pipe orifice can be reduced as much as possible. Generally, in order to ensure that the fresh air duct has a proper air inlet amount, the cross-sectional area of the air passing channel is 0.5-1.1 times of the cross-sectional area of the fresh air duct. The sum of the sectional areas of the air passing holes on the wind-proof plate is generally 0.5-1.1 times of the sectional area of the pipeline of the fresh air fan.
When wind blows on the wind cap, the wind quantity in a certain range (about the surface area of the wind cap) can be concentrated and collected, and the wind tends to blow straight to one side of the wall body along the surface of the wind cap. In an alternative embodiment, the end of the outer hood facing the cavity is provided with a turned-over edge 13. The wind blowing to the pipe orifice from the outside can blow outwards along the trend, but can not blow to the surface of the wall body directly, and the possibility that the wind returns to the interior of the wind cap is reduced to the maximum extent.
It should be noted that the cone end of the outer cap body is provided with an opening, and the wind blowing to the cap portion blows a part of the wind along the outer wall of the cap (in the above embodiment, the part of the wind is blocked by the curled edge 15 and blows outward along the wind), while the other part of the wind blowing to the space between the outer cap body and the inner cap body is blocked by the supporting plate and is blocked outside the inner cap body.
The inner and outer wind cap bodies are designed, namely, the condition that wind power is concentrated on the outer wall of the wind cap and is directly blown to one side of the wall body is further weakened, namely, the wind power borne by the common wind cap is dispersed, the stress of the wind cap structure is dispersed, the stability cannot be influenced, and the obtained effect is that the wind is prevented from being poured into the pipe orifice to the maximum extent.
The wind-proof structure is reasonable in design, the air passing channel formed between the first wind-proof bent part and the second wind-proof bent part can ensure smooth exchange of indoor air and outdoor air, the possibility of 'wind filling' at the position of the pipe orifice is avoided as far as possible, even if wind blowing to the wind cap does not easily flow back into the wind cap and then is filled into the pipe orifice, and the wind-proof capability is improved to the maximum extent.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the invention, so that any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present invention, should be included in the scope of the present invention.
