Detailed Description

The present invention will be further explained with reference to the accompanying drawings and examples.

As shown in fig. 1, a schematic structural diagram of a construction site project management board room of the present invention is given, a board room 1 is built on a foundation 2, an air inlet pipeline 3 and an air outlet pipeline 4 are arranged on the board room 1, and an air outlet of the air inlet pipeline 3 is arranged at an upper portion of the board room 1 and is used for introducing external air into the board room 1; the air inlet of the air outlet pipeline 4 is positioned at the lower part of the board room 1 and is used for pumping out the air inside the board room 1. The upper end of the air inlet pipeline 3 is provided with an air inlet device 5, the upper end of the air outlet pipeline 3 is provided with an air outlet device 6, an air inlet of the air inlet device 5 faces the incoming air direction all the time, and an air outlet of the air outlet device 6 faces the incoming air direction all the time.

Because the air inlet device 5 always faces to the incoming air direction, the automatic blowing of the external air into the air inlet pipeline 3 and then into the board room 1 is realized. Because the air outlet device 6 always faces back to the incoming air direction, the air in the board room 1 is extracted through the air outlet pipeline 4. Thus, under the combined action of the air inlet device 5 and the air outlet device 6, outside air is blown in through the upper part of the board room 1 and then flows out through the lower part of the board room 1, so that air exchange inside the board room 1 is realized when a door and a window are not opened, and the entrance of outside engineering operation noise is avoided; meanwhile, as the air in the board room 1 flows from top to bottom, the floating and flying of dust on the ground of the board room are avoided, and the air in the board room is ensured to be in a good state all the time.

When the outside temperature is too low or too high, in order to avoid the entering of the outside air, the air outlet of the air inlet pipeline 3 and the air inlet of the air outlet pipeline 4 are both provided with manual valves, and when air exchange is not needed, the air inlet pipeline 3 and the air outlet pipeline 4 are both closed through the manual valves. The air outlet of the air inlet pipe 3 is provided with replaceable filter cotton 7 to prevent external dust from entering.

As shown in fig. 2, the utility model discloses the local cross-sectional view at well hot blast blowpipe apparatus place position is given, shown hot blast blowpipe apparatus 5 comprises pivot 14, vertical section of thick bamboo 8, horizontal cylinder 9, horn mouth 10, lower bearing 11, upper bearing 12 and wind rudder 16, and vertical section of thick bamboo 8 is linked together and becomes 90 degrees contained angles with horizontal cylinder 9, and the outer end of horizontal cylinder 9 is connected with the horn mouth 10 that expands outward. The upper part of the air inlet pipeline 3 is vertically arranged, and the vertical cylinder 8 is inserted at the upper end of the air inlet pipeline 3. The upper bearing 12 and the lower bearing 11 are located at the central position of the upper part of the air inlet pipeline 3, the bearing seats of the upper bearing 12 and the lower bearing 11 are fixed on the inner wall of the air inlet pipeline 3 through the first connecting rod 13, and the rotating shaft 14 is arranged on the upper bearing 11 and the lower bearing 12, so that the rotating shaft 14 and the upper end of the air inlet pipeline 3 are coaxially arranged.

The upper end of the rotating shaft 14 is fixedly connected with the inner wall of the vertical cylinder 8 through a plurality of second connecting rods 15 so as to ensure that the horizontal cylinder 9 and the vertical cylinder 8 rotate together with the rotating shaft 14. Wind rudder 16 is through third connecting rod 17 and horizontal cylinder 9 fixed connection, wind rudder 16 adopts vertical flat board, wind rudder 16 and bellmouth 10 are located the both sides of pivot 14 respectively, like this, under the effect of external wind force, wind rudder 16 can be in leeward all the time and ascending, this also makes bellmouth 10 be in the upwind direction, be towards the incoming wind direction promptly, like this, external air can get into through bellmouth 10, and then blows in board room 1 through intake stack 3.

Except that the position of the wind direction rudder 16 of the air outlet device 6 is different from that of the air inlet device 5, the rest structures are the same as the air inlet device 5, the wind direction rudder and the bell mouth in the air outlet device are positioned on the same side of the rotating shaft, and thus the wind direction rudder and the bell mouth on the air outlet device 6 are both positioned in the downwind direction, namely the bell mouth on the air outlet device faces away from the incoming wind direction, so that the air in the board room 1 is extracted through the air outlet pipeline 4.
