Referring to fig. 2, the air outlet pipe 2 includes an installation portion 21, a connection portion 22, and an air outlet portion 23, which are fixedly connected in sequence, the installation portion 21 is fixed to an air outlet end of the axial flow fan 1, the installation portion 21 is parallel to the air outlet portion 23, and the air outlet portion 23 is located below the installation portion 21. In addition, the connecting portion 22 is arc-shaped, one end of the connecting portion 22 is fixedly connected to the mounting portion 21, and the other end of the connecting portion is fixedly connected to one end of the air outlet portion 23. After the axial flow fan 1 blows air, the air can be blown out through the mounting portion 21, the connecting portion 22, and the air outlet portion 23 in this order.
A plurality of air outlet holes 221 are formed on the side wall of one end of the connecting part 22 of each air outlet pipe 2 close to the outlet of the tunnel 9. When the axial flow fan 1 is operated to blow air into the connection portion 22, a part of the air is blown out through the position of the air outlet hole 221, and at the same time, the air is blown out from the position of the air outlet portion 23, so that the flow direction of the air blown out by the axial flow fan 1 can be increased, and the flow of the air in the tunnel 9 can be more sufficiently enhanced.
As shown in fig. 2, an air inlet pipe 6 is provided at an air inlet end of each axial-flow fan 1, and a first dust screen 61 is fixedly connected to the air inlet pipe 6. Through the arrangement of the first dust screen 61, some impurities in the tunnel 9 can be prevented from entering the axial-flow fan 1, so that the operation of the axial-flow fan 1 is influenced.
The two side edges of the casing of the axial flow fan 1 are respectively and fixedly connected with a connecting plate 81, the edge of one end of the air inlet pipe 6 is fixedly connected with an annular first locking plate 82, and the first locking plate 82 is attached to the connecting plate 81 at the air inlet end of the casing of the axial flow fan 1 and fixedly connected with the connecting plate through bolts. An annular second lock plate 83 is fixedly connected to the end of the mounting portion 21 not connected to the connection portion 22, and the second lock plate 83 is attached to a connection plate 81 at the casing air outlet end of the axial flow fan 1 and fixedly connected thereto by bolts. Thus, the air inlet pipe 6 and the air outlet pipe 2 can be respectively fixed on the axial-flow fan 1.
It should be noted that the arrangement of the axial flow fan 1 and the air outlet pipe 2 needs to be set according to the size of the tunnel 9, so that the normal operation of the tunnel 9 is not affected.
As shown in fig. 3, air outlet channels 3 are respectively disposed inside two side walls of the tunnel 9, the direction of the air outlet channel 3 is the same as the direction of the tunnel 9, and the outlet end of the air outlet channel 3 penetrates through the tunnel 9, so that the air in the air outlet channel 3 can flow to the outside.
There are a plurality of through-holes 41 in the position that tunnel 9 both sides wall corresponds air-out passageway 3, a plurality of through-holes 41 equidistant setting, be provided with on every through-hole 41 with the air suction fan 4 in the air-out passageway 3 of air suction in tunnel 9, even on air suction fan 4 fixed connection to through-hole 41, make the air-out end of air suction fan 4 just to air-out passageway 3, the air inlet end is just to inside tunnel 9, when making air suction fan 4 move, can take out the partial air in tunnel 9 in the air-out passageway 3 and discharge, further strengthen the air flow in the tunnel 9.
As shown in fig. 3, an arc-shaped guide piece 5 is disposed on an edge of one end of each through hole 41, which is located at the air outlet end of the exhaust fan 4, one end of each guide piece 5 is fixedly connected to an edge position of the through hole 41, which is far away from the outlet of the air outlet channel 3, the other end of each guide piece 5 faces the direction of the outlet of the air outlet channel 3, and a gap is formed between each guide piece 5 and a side wall of the air outlet channel 3, which is directly opposite to the through hole 41, that is, the guide pieces 5 are not in contact with the side.
Through the above arrangement, after the air of the tunnel 9 is drawn away by the exhaust fan 4, the air flow towards the outlet end of the air outlet channel 3 is formed by the guide of the guide sheet 5, so that the air flow rapidly flows to the outside, and the guide sheet 5 is not in contact with the side wall of the air outlet channel 3, so that the air in the air outlet channel 3 cannot flow out.
The edge of each through hole 41 is fixedly connected with a funnel-shaped air inlet channel 7, and the relatively smaller end of each air inlet channel 7 is fixedly connected to the edge of the through hole 41, so that the air in the tunnel 9 can be more fully pumped into the air outlet channel 3.
In addition, a second dustproof net 71 is fixedly connected in the air inlet channel 7, and through the arrangement of the second dustproof net 71, sundries in the tunnel 9 can be prevented from entering the exhaust fan 4, so that the operation of the exhaust fan 4 is influenced.
The axial fans 1 are spaced apart from the suction fans 4, that is, each axial fan 1 is spaced apart from each suction fan 4 by a certain distance, for example, after one axial fan 1 is disposed in the tunnel 9, the axial fan 1 is continuously advanced to the tunnel 9 by a distance of ten meters and the suction fans 4 are installed on the side walls of the tunnel 9 at the position. This further enhances the mobility of the air in the tunnel 9.
The utility model discloses a set up axial fan 1 in tunnel 9, make its operation, can be relatively abundant blow off the air in tunnel 9, and when air exhauster 4 was operated, can take away the air in tunnel 9 to make the outer air in tunnel 9 in time mend and come in, thereby can strengthen the air mobility in tunnel 9, make the circulation of air effect in tunnel 9 better, so that guarantee constantly in the tunnel 9 has fresh air.
Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
