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 is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0025] like 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 the two ends of the main body 3, and the two cleaning mechanisms are respectively The 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 energy and prolongs the jet distance of the jet fan. Not only that, the cleaning mechanism reduces the number of debris entering the jet fan and reduces the risk o...

Abstract

The invention relates to a high-efficiency jet fan with wind direction adjustment function, which includes a main body, two adjustment mechanisms and two cleaning mechanisms. The adjustment mechanism includes an annular guide rail, an annular groove, a steering ring, a first drive assembly, a second drive Assembly, bellows, torsion spring and guide ring, the cleaning mechanism includes a moving rod, cleaning brush, dust filter and two support assemblies, the first drive assembly includes a second motor, gear and ring rack, and the second drive assembly includes a second drive assembly A motor, a winding reel, connecting wires and fixed pulleys, and the support assembly includes a sliding rod, a spring and a sliding sleeve. In this high-efficiency jet fan with the function of adjusting the wind direction, the wind direction of the jet fan can be adjusted through the adjustment mechanism, which reduces the air flow. The loss of energy prolongs the air jetting distance of the jet fan, reduces the number of debris entering the interior of the jet fan through the cleaning mechanism, reduces the probability of damage to the jet fan, and improves the working efficiency of the jet fan.

Description

technical field [0001] The invention relates to the field of urban rail transit equipment, in particular to a high-efficiency jet fan with the function of adjusting the wind direction. Background technique [0002] The jet fan is a special axial fan, mainly used in the longitudinal ventilation system of tunnels such as roads, railways and subways, providing full thrust; it can also be used in sensitive parts of semi-horizontal ventilation systems or transverse ventilation systems, such as tunnels The inlet and outlet of the inlet and outlet play the role of inducing air flow or exhausting smoke. [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, sundries are easily sucked into the inside of the fan, cau...
