In some embodiments, the plurality of annular frames 342 and the plurality of upright frames 341 are removably coupled in a mating manner, and, in particular, as shown in fig. 4 to 5, the ring frame 342 is divided into an inner ring frame 3422 and an outer ring frame 3421, the inner ring frame 3422 is provided with a plurality of inwardly opened grooves, the outer ring frame 3421 is provided with a plurality of outwardly opened grooves, and one end of the outer ring frame is hinged, and the other end is provided with a mounting part, the vertical support 341 is provided with a plurality of mounting grooves which are arranged in a staggered way, the mounting grooves are used for matching the inner ring frame 3422 and the outer ring frame 3421, the inner ring frame 3422 is used for fixing and supporting the vertical support 341, then the outer ring frame 3422 is sleeved, at this time, the outer ring frame 3421 is fixed through the mounting part and is arranged in sequence, the vertical supports are fixed by the pulling force of the inner ring support 3422 and the supporting force of the outer ring support 3421, furthermore, the bearing plate is an original plate provided with a plurality of through holes for running through the vertical supports 341, and a central hole is left in the middle of the original plate for passing through a ventilation pipe or an extension pipeline; the carrier plate is placed on the annular frame 342 to support the extension pipes; it should be noted that, the purpose of this setting is that, because the originally leaked ventilation pipes on the roof are not uniform in height, when the original scaffold or other existing installation methods are adopted, scaffolds with different heights need to be configured to fix the ventilation pipes, which may cause waste of equipment and instable installation; therefore, in the application, the height of the spliced or welded bearing plate is adjustable, and the bearing plate is used for being matched with ventilation pipes with different heights to bear extension pipelines, and the connection modes between the extension pipelines and between the extension pipelines and the ventilation pipes are common connection modes in the market, such as bonding, flange plate connection, buckle connection and the like; in addition, because the ventilation pipe is directly positioned in the activity space of human and is in static distance contact with human, the whole pipeline has high requirement limitation, and the area in the activity space cannot be wasted; the annular frame aims to reduce the occupied amount of the ventilation pipe on the activity space by utilizing the area advantage of the annular frame, because the circumference of the annular frame is the shortest under the same area; moreover, the arc-shaped screen can be manufactured on the arc-shaped outer side of the annular frame to be matched with various displays in the activity space to enhance the display effect, and the arc-shaped screen is a screen which can be purchased in the market.

In some embodiments, the exhaust pipe is positioned in the multilayer space of the air conditioner, so that the existing ventilation pipe equipment is reasonably utilized in order to save the area of the movable space, and meanwhile, because the air conditioner is positioned on the roof and is directly irradiated by sunlight, the temperature inside the movable space is higher relative to the temperature inside the building, and more refrigeration equipment is needed to meet the requirement of cooling in the closed space; as shown in fig. 3, the exhaust pipe includes an outer pipe 710 and an inner pipe 720 disposed in the outer pipe 710, the inner surface of the inner pipe 720 is provided with a spiral piece 730 spiraling upward, no matter whether the left-hand rule or the right-hand rule is satisfied, only the spiral direction is needed, a fan 750 for blowing air along the tangential direction of the inner pipe 720 is disposed in the blade of the spiral piece 730, as shown in fig. 9, the horizontal length of the air-out surface of the fan 750 is not less than 80% of the radial length of the inner pipe 720, that is, the air outlet of the fan should be from 80% of the horizontal radius of the inner pipe 720 covered by the inner and outer sides, the blown air rotates along the spiral piece 730 spiraling on the inner pipe 720, because the rotational angular velocity of the air on the outer diameter is less than the rotational angular velocity of the air on the inner diameter on the same horizontal plane, a vortex phenomenon occurs, so that the temperature of the air on the, in the traditional vortex refrigeration, the lowest temperature of the existing equipment can reach minus 50 ℃, but in the application, the lowest temperature is only reduced by a few degrees relative to the external temperature due to the ventilation limitation, so that the purpose of indoor temperature reduction is achieved;

the dust removing holes 740 are formed on the wall of the inner pipe 720 without any obstacle as viewed from the outer pipe 710 toward the inner pipe 720, and are formed only on a plane, so that there is only a wind pressure per unit volume at this time, and the dust is more likely to be transmitted from the inner pipe to the outer pipe in terms of the size of the contact surface, thereby collecting the dust in the interlayer between the inner pipe 720 and the outer pipe 710; the interlayer of the inner pipe 720 and the outer pipe 710 is provided with a dust layer 771, a sound insulation layer 772 and a heat insulation layer 773 in sequence from inside to outside; a dust removal window 780 is arranged at the joint of the outer pipe 710, and the dust removal window 780 is communicated with the dust removal layer 771; it should be noted that the dust-removing layer 771, the sound-insulating layer 772 and the heat-insulating layer 773 are all devices or equipment available in the market, and the dust-removing layer 771 adsorbs or collects dust passing through the dust-removing holes 740, and the dust or the dust-removing layer 771 is taken out through the dust-removing window; of course, the first extension pipeline and the second extension pipeline may be arranged in this way, and when the first extension pipe and the second extension pipe are arranged in this way, the fan should not be arranged at the air outlet.

In some embodiments, parapet 320 is provided with an aperture through exhaust 340, and exhaust 340 is drawn out of the wall through the aperture.
