[0002] Axial flow fans are the most commonly used ventilation and air supply equipment on the market. When in use, the gas flows parallel to the fan shaft, that is, the airflow is in the same direction as the shaft of the fan blade, so it is called "axial flow". For example, electric fans and air conditioner outdoor fans are axial flow fans. Axial flow fans have the characteristics of simple structure, obvious ventilation effect, safety, stability and reliability. They are usually used in places with high flow requirements and low pressure requirements, such as industrial production workshops and civil buildings for ventilation or heat dissipation.

[0021] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "set", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] like Figure 1-4 As shown, the utility model is an axial flow fan for high-temperature fluid transportation, comprising: a fan body 1; a bracket 2, the bracket 2 is connected to the outside of the fan body 1; a rotating shaft 3, the fan body 1 is rotatably connected to the bracket 2 through the rotating shaft 3; a locker 4, the locker 4 is connected to the rotating shaft 3; a lifting slide bar 5, the upper part of the lifting slide bar 5 is connected to the bracket 2, and the lifting slide bar 5 is provided with a plurality of threaded holes 7; an adjusting cylinder 6, the adjusting cylinder 6 is detachably connected to the lifting slide bar 5 through a fixing bolt 8; a bottom frame 9, the upper part of the bottom frame 9 is connected to the adjusting cylinder 6, and a universal wheel 10 and an anti-slip pad 11 are arranged at the bottom of the bottom frame 9.

[0023] In this embodiment, by unlocking the lock 4 and the fixing knob 16, the angle of the fan body 1 can be adjusted by rotating the shaft 3 to change the wind direction of the air. By removing the fixing bolt 8, the two lifting slide bars 5 are adjusted to move upward or downward in the two adjusting cylinders 6 respectively, so that the two adjusting cylinders 6 move vertically to adjust the height position of the bracket 2 and the fan body 1, thereby facilitating the adjustment of the height position of the axial flow fan, making the wind direction range wider and enhancing the applicability of the device.

[0024] like Figure 3 and Figure 4 As shown, the universal wheel 10 is connected to the adjusting rod 12 at the top, and the adjusting rod 12 is rotatably connected to the mounting cylinder 14 through the rotating shaft 13.

[0025] In this embodiment, the rotating shaft 13 can be driven to rotate inside the mounting tube 14 by pushing the adjusting rod 12, so that the position of the universal wheel 10 can be adjusted. When the axial flow fan needs to be moved, the universal wheel 10 can be pushed out from the bottom frame 9 by pushing the adjusting rod 12, so that the universal wheel 10 contacts the ground. The universal wheel 10 is convenient for moving the axial flow fan, saving time and effort. When the axial flow fan needs to be fixedly installed for a long time, the universal wheel 10 can be pushed back into the bottom frame 9 by pushing the adjusting rod 12, so that the anti-slip pad 11 at the bottom of the mounting frame 9 contacts the ground, increasing the friction between the ground and the fan, preventing the axial flow fan from shifting due to accidental contact, and enhancing the stability of the axial flow fan during use.

[0026] like Figure 1 and Figure 2 As shown, specifically, the lower part of the lifting slide bar 5 is detachably connected to the bottom frame 9, a plurality of threaded holes 7 are evenly spaced on the lifting slide bar 5, the fixing bolts 8 are matched with the threaded holes 7, and the anti-skid pad 11 is glued to the bottom of the bottom frame 9; the lower part of the lifting slide bar 5 is detachably connected to the bottom frame 9, so that the lifting slide bar 5 can be easily installed and disassembled, which is convenient for later maintenance.

[0027] like Figure 1 and Figure 2 As shown, a chuck 15 is provided between the rotating shaft 3 and the locker 4, and a fixing knob 16 is provided on the chuck 15; the rotation range of the fan can be limited by the hole groove on the chuck 15, and the fixing knob 16 can cooperate with the locker 4 to lock and fix it, thereby enhancing firmness.

[0028] like Figure 1 and Figure 2 As shown, specifically, two installation tubes 14 are provided, both ends of each installation tube 14 are connected to the rotating shaft 13, and two brackets 2, lifting slide rods 5 and adjustment tubes 6 are provided.

[0029] Working principle: The staff unlocks the lock 4 and the fixed knob 16, and can adjust the angle of the fan body 1 by rotating the shaft 3 to change the wind direction. By removing the fixing bolt 8, the two lifting slide bars 5 are adjusted to move upward or downward in the two adjustment cylinders 6 respectively, so that the two adjustment cylinders 6 move vertically to adjust the height position of the bracket 2 and the fan body 1, which is convenient for adjusting the height position of the axial flow fan, making the wind direction range wider and enhancing the applicability of the device. By pushing the adjustment rod 12, the rotating shaft 13 can be driven to rotate inside the installation cylinder 14. The universal wheel 10 can be moved so that the position of the universal wheel 10 can be adjusted. When the axial flow fan needs to be moved, the universal wheel 10 can be pushed out from the bottom frame 9 by pushing the adjusting rod 12, so that the universal wheel 10 contacts the ground. The axial flow fan can be conveniently moved through the universal wheel 10. When the axial flow fan needs to be fixedly installed for a long time, the universal wheel 10 can be pushed back into the bottom frame 9 by pushing the adjusting rod 12, so that the anti-slip pad 11 at the bottom of the installation frame 9 contacts the ground, thereby increasing the friction between the ground and the axial flow fan, preventing the axial flow fan from shifting due to accidental contact, and enhancing the stability of the axial flow fan when in use.
