When the tower height of the crossing tower is high, a shaft type elevator generally needs to be arranged in the middle, a hollow steel pipe is adopted in an outer shaft of the shaft type elevator, and a ventilating pipe needs to be arranged on the shaft to keep the pressure inside and outside the shaft in order to avoid excessive pressure generated inside the shaft when the elevator runs. The condition that rainwater flows back along the pipe wall can occur in a high-altitude elevator shaft ventilation pipe in strong wind and heavy rain, the repentance of rainwater after entering the shaft type elevator seriously influences the safe operation and equipment maintenance of the elevator, elevator equipment is damaged, and potential safety hazards can be brought when the elevator is used.
Disclosure of Invention
The to-be-solved technical problem of the utility model lies in, to the above-mentioned defect of prior art, a transmission line crossing tower's that low in manufacturing cost just can effective wall rainwater flow backward ventilation tube structure is provided.
The utility model aims at providing a transmission line crossing tower ventilation pipe structure, which comprises a plurality of ventilation pipe bodies circumferentially and uniformly arranged on a shaft outside the transmission line, wherein each ventilation pipe body comprises a first ventilation pipe which gradually inclines downwards from inside to outside and a second ventilation pipe which is vertically arranged at the bottom of the first ventilation pipe; a rubber ring is arranged in the first ventilation pipe, an inward-sunken annular groove is formed in the outer side wall of the rubber ring, a mounting seat is integrally formed on the outer wall of the middle lower part of the rubber ring, and the outer diameter of the mounting seat is larger than that of the rubber ring; the rubber ring is inversely arranged in the first ventilation pipe through the mounting seat and is used for blocking rainwater inversely filled into the first ventilation pipe, and a drainage groove for draining the inversely filled rainwater is formed in a relative space between the annular groove and the first ventilation pipe.
Furthermore, a rubber hose is sleeved on the outer wall of the lower portion of the second ventilation pipe through a hoop, and the length of the rubber hose is larger than that of the second ventilation pipe.
Further, the outer wall of the mounting seat of the rubber ring is tightly arranged in the first ventilation pipe, and the mounting seat and the first ventilation pipe are bonded and fixed through sealant.
Further, the included angle between the first ventilating pipe and the horizontal plane is 30-45 degrees.
Further, the outer surface of the rubber hose is coated with a layer of anti-aging protective film.
The utility model has the advantages of: the utility model adds the rubber ring on the inner wall of the ventilation pipe, the rubber ring is fixed in the ventilation pipe through the sealant, the drainage groove is arranged in the rubber ring, and the rainwater entering along the upper part of the inner wall of the pipe along the wind can be blocked and drained away; in addition, the rubber hose arranged on the outer side of the ventilation pipe does not influence ventilation at ordinary times, and the air inlet can be reduced in rainy days, so that rainwater is prevented from flowing back into the ventilation pipe.
Drawings
Fig. 1 is a schematic structural diagram of an external shaft of a power transmission line according to the present invention;
FIG. 2 is a schematic view of the overall structure of the present invention;
fig. 3 is a schematic structural view of the rubber ring of the present invention.
Detailed Description
To make the objects, technical solutions and advantages of the present invention more clearly understood by those skilled in the art, the present invention will be further described with reference to the accompanying drawings and examples.
In the description of the present invention, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "left", "right", "inner", "outer", "transverse", "vertical", and the like are directions or positional relationships based on the directions or positional relationships shown in the drawings, and are only for convenience of description of the present invention, and do not indicate or imply that the device or element indicated must have a specific direction, and therefore, the present invention should not be construed as being limited thereto.
As shown in fig. 1-3, a transmission line stridees across ventilation pipe structure of tower, evenly set up a plurality of ventilation pipe bodies 2 on transmission line outside pit shaft 1 including circumference, ventilation pipe body 2 includes by interior to exterior first ventilation pipe 21 and the vertical second ventilation pipe 22 that sets up in first ventilation pipe 21 bottom of downward sloping gradually, the contained angle between first ventilation pipe 21 and the horizontal plane is 30 ~ 45. The structure of buckling downwards that first ventilation pipe 21 and second ventilation pipe 22 are constituteed can effectively avoid the entering of rainwater, but just so still not enough, because rainwater can flow into the ventilation pipe body along with strong wind weather is internal, then is blown into the shaft tube formula elevator by wind. In order to avoid the above situation, the present invention provides a rubber ring 3 in the first ventilation pipe 21, an inward recessed ring groove 31 is provided on the outer side wall of the rubber ring 3, an installation seat 32 is integrally formed on the outer wall of the middle and lower parts of the rubber ring 3, and the outer diameter of the installation seat 32 is larger than the outer diameter of the rubber ring 3; the rubber ring 3 is inversely arranged 32 in the first vent pipe 21 through the mounting seat and is used for blocking rainwater inversely poured into the first vent pipe 21, in more detail, the outer wall of the mounting seat 32 of the rubber ring 3 is tightly arranged in the first vent pipe 21, and the mounting seat 32 is fixedly bonded with the first vent pipe 21 through sealant.
