Problems solved by technology
[0003] When the jet fan in the prior art is in use, the airflow blown by the fan has a divergence angle, which makes the airflow easily rub against the tunnel, causing a large amount of airflow energy loss and shortening the jetting distance of the jet fan. Not only that, the existing technology When the jet fan is in use, debris is easily sucked into the fan, which will cause damage to the fan and reduce the practicability of the fan

Embodiment Construction
[0024] The present invention will now be described in further detail with reference to the drawings. These drawings are all simplified schematic diagrams, which merely illustrate the basic structure of the present invention in a schematic manner, so they only show the structures related to the present invention.
[0025] Such as figure 1 As shown, a high-efficiency jet fan with wind direction adjustment function includes a main body 3, and also includes two adjustment mechanisms and two cleaning mechanisms. The two adjustment mechanisms are respectively connected to both ends of the main body 3, and the two cleaning mechanisms are respectively connected with Two adjustment mechanisms are connected;
[0026] The wind direction of the jet fan can be adjusted through the adjustment mechanism, which reduces the loss of air flow energy and extends the air jet distance of the jet fan. Not only that, the cleaning mechanism reduces the amount of debris entering the jet fan and reduces the ...

The invention relates to an efficient jet fan having a wind direction adjusting function. The jet fan comprises a main body and further comprises two adjusting mechanisms and two cleaning mechanisms;each adjusting mechanism comprises a circular guiding rail, a circular groove, a turning ring, a first driving component, a second driving component, a corrugated pipe, a torsion spring and a guidingring; each cleaning mechanism comprises a moving rod, a cleaning brush, a dustproof net and two supporting components; each first driving component comprises a second motor, a gear and a circular rack; each second driving component comprises a first motor, a wire reel, a connecting wire and a fixed pulley; and each supporting component comprises a sliding rod, a spring and a sliding casing pipe. According to the efficient jet fan having the wind direction adjusting function, the wind direction of the jet fan can be adjusted by the aid of the adjusting mechanisms, so that the loss of airflow energy is reduced, and the airflow jetting distance of the jet fan is lengthened; and by the aid of the cleaning mechanisms, the quantity of sundries entering the jet fan is reduced, the damage probability of the jet fan is reduced, and the working efficiency of the jet fan is improved.
Description
Technical field [0001] The invention relates to the field of urban rail transit equipment, in particular to a high-efficiency jet fan with a wind direction adjustment function. Background technique [0002] Jet fan is a special axial flow fan, which is mainly used in the longitudinal ventilation system of highway, railway and subway tunnels to provide all thrust; it can also be used in semi-transverse ventilation system or sensitive parts in transverse ventilation system, such as tunnel The inlet and outlet of the air-conditioning system can induce airflow or exhaust smoke. [0003] When the jet fan of the prior art is in use, the airflow blown by the fan has a diffusion angle, which makes the airflow easy to friction with the tunnel, causing a large amount of airflow energy loss, and shortening the air jet distance of the jet fan. Not only that, the prior art When the jet fan is in use, the sundries are easily sucked into the fan, causing damage to the fan and reducing the practi...
