DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be apparently and completely described below in combination with the drawings in the embodiments of the utility model. In the following description, a large number of specific details are set forth in order to give a thorough understanding of the utility model, but the utility model can also be implemented in other manners different from those described herein, and those skilled in the art can make similar generalization without departing from the connotation of the utility model, therefore the utility model is not limited by the specific embodiments disclosed below.

[0025] Please refer to Figures 1 to 4 Fig. 1 shows a kind of roof venting vertical pipe assembly, including vent pipe 1, air pipe assembly 2 and wind vane 3, vent pipe 1 is the cylindrical structure of two ends opening, it is fixed in the outside of roof, its bottom is communicated with the drainage system of building, for the venting and removal of waste gas of drainage system. Figure 3 And Figure 4 As shown in Fig. 2, in the embodiment, vent pipe 1 includes pipe body 11, buffer layer 12 and anti-collision layer 13 from inside to outside in sequence, pipe body 11 is made of hard plastic (PVC), with the advantages of acid resistance, alkali resistance, corrosion resistance and long service life. Anti-collision layer 13 is coated on the outside of vent pipe 1, to avoid external object impact causing pipe body 11 damage, preferably, the material of anti-collision layer 13 is stainless steel. Buffer layer 12 is arranged between anti-collision layer 13 and pipe body 11, to further prevent pipe body 11 damage, preferably, the material of buffer layer 12 is rubber, because rubber material has certain elasticity and toughness, when anti-collision layer 13 receives external impact, buffer layer 12 can effectively absorb impact force, to a certain extent, slow down the damage degree of pipe body 11 when impacted.

[0026] Preferably, anti-collision layer 13 is coated with black anticorrosive layer (not shown in the figure) on the outside, to avoid anti-collision layer 13 being corroded by external environment. At the same time, because black object can absorb all color light, so black object is easy to absorb heat under sunlight, and transfer heat to the inside of pipe body 11, after air in pipe body 11 absorbs heat, density becomes smaller, air becomes lighter, to generate upward movement of the driving force, to facilitate the waste gas in drainage system to be quickly discharged, that is, by setting black anticorrosive layer, to produce air extraction effect on the waste gas in drainage system, to realize effective discharge of waste gas in drainage system.

[0027] Please refer to Figure 1 and Figure 3 As shown in the figure, the wind pipe assembly 2 is rotatably and communicatively arranged at the top end of the vent pipe 1, and the ventilation direction of the wind pipe assembly 2 is perpendicular to the exhaust direction of the vent pipe 1, so that the external natural wind can pass through the wind pipe assembly 2 and take away the exhaust gas in the vent pipe 1, while preventing foreign objects from falling into the vent pipe 1 and causing the vent pipe 1 to be blocked. In this embodiment, the wind pipe assembly 2 includes a sleeve 21 and a reducer 22, and the top end of the vent pipe 1 is coaxially sleeved with a bearing 4, and the bottom end of the sleeve 21 is fixedly provided with a protruding ring 211, which is fixedly sleeved on the outer surface of the bearing 4 to realize the rotational connection of the wind pipe assembly 2 and the vent pipe 1.

[0028] The reducer 22 is communicatively arranged at the top end of the sleeve 21, and the reducer 22 includes an air inlet 221 and an air outlet 222. The external natural wind enters through the air inlet 221 of the reducer 22 and is discharged from the air outlet 222 of the reducer 22. By arranging the bearing 4 to realize the rotational connection of the wind pipe assembly 2 and the vent pipe 1, the orientation of the air inlet 221 of the reducer 22 can be adjusted according to the wind direction, and preferably, the opening area of the air inlet 221 of the reducer 22 is larger than that of the air outlet 222. According to the Venturi effect, since the air outlet 222 is smaller than the air inlet 221, the wind flowing into the air inlet 221 will increase in speed when flowing through the air outlet 222, thus causing a certain negative pressure at the communication position of the reducer 22 and the vent pipe 1, which is beneficial to the extraction of the exhaust gas in the vent pipe 1, thereby enhancing the exhaust effect.

[0029] Please refer to Figure 1 and Figure 2 As shown in the figure, the wind vane 3 is fixedly arranged at the top end of the wind pipe assembly 2 and is used to guide the wind pipe assembly 2 to rotate according to the wind direction, so that the external natural wind can smoothly enter the air inlet 221 of the reducer 22. In this embodiment, the wind vane 3 includes two fixed rods 31 arranged on both sides of the ventilation direction of the reducer 22, respectively, one end of each of the two fixed rods 31 is fixedly connected with the top surface of the reducer 22, and the other end of each of the two fixed rods 31 extends vertically upward and is fixedly connected with a horizontal pointing rod 32, one end of the pointing rod 32 close to the air inlet 221 of the reducer 22 is provided with a counterweight 33, and the other end of the pointing rod 32 is fixedly provided with a wind wing 34 for adjusting the ventilation direction of the reducer 22 to be parallel to the wind direction. The wind wing 34 includes two wind vanes 341 symmetrically arranged on the radial sides of the pointing rod 32, one side of each of the two wind vanes 341 is fixedly connected with the pointing rod 32, and the other side of each of the two wind vanes 341 extends outwardly and away from the central axis of the pointing rod 32.

[0030] When the natural wind from the outside world is at a certain intersection angle with the wind vane 3 in implementation, the wind produces pressure on the wind wing 34, the two rudders 341 of the wing plate are unbalanced in force, the natural wind from the outside world will drive the rudder 341 with greater force to move to the direction of the rudder 341 with smaller force, thereby driving the wind vane 3 and the wind pipe assembly 2 to rotate, until the balance weight 33 points to the source of the wind, at this time the two rudders 341 of the wing plate are balanced in force, thereby making the wind vane 3 drive the wind pipe assembly 2 to be stable at a certain direction. In other words, the resistance to air flow generated by the wing plate is greater than the resistance to air flow generated by the balance weight 33, so the end with greater resistance to air flow will rotate with the wind, so the balance weight 33 always points to the source of the wind, and since the balance weight 33 is arranged at one end close to the air inlet 221 of the reducing pipe 22, the air inlet 221 of the reducing pipe 22 always keeps opposite to the wind direction.

[0031] In the specific implementation of the utility model, the wind vane 3 drives the air inlet 221 of the reducing pipe 22 to keep opposite to the wind direction at all times through the resistance to air flow generated by the wing plate, so that the wind is discharged from the air inlet 221 to the air outlet 222, and since the air outlet 222 is smaller than the air inlet 221, the wind flowing into the air inlet 221 will increase in flow rate when flowing through the air outlet 222, so that a certain negative pressure is generated at the communication part of the reducing pipe 22 and the air pipe 1, which is beneficial to the exhaust gas in the air pipe 1, thereby enhancing the effect of exhausting the exhaust gas. When there is no wind outside, the black corrosion-resistant layer transmits heat to the inside of the pipe body 11, the air in the pipe body 11 becomes lighter after absorbing heat, and generates upward driving force, thereby promoting the exhaust gas in the drainage system to be quickly discharged.

[0032] The above description is only for the preferred embodiments of the utility model, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.
