Abstract
The invention discloses a double-fan air duct with an automatic switching air opening. The double-fan air duct comprises a first air duct body and a second air duct body, an air opening switching component is arranged at the joint position of the first air duct body and the second air duct body and comprises a rotary shaft and a baffle matched with the first air duct body and the second air duct body, the rotary shaft is connected with a driving motor, and the driving motor is connected with a detector. According to the technical scheme, automatic air opening switching can be achieved, manual intervention is not needed, and switching is more timely and efficient.
Description
Technical field
The present invention relates to two fans technical field of mechanical equipment, especially relate to a kind of two fans air duct being provided with automatic switchover air port.
Background technique
Two fans is used for the half-finished cooling of high temperature in the industry such as melting furnaces, metallurgy manufacture, is important cooling unit.In existing two fans structure, be the using and the reserved mostly, object ensures when there is machine halt trouble, and work can be opened in time in two fans air port for subsequent use.When use two fans switches air port, need the air duct that manual switching is different, so just increase the labor intensity of staff, and switch not in time, the reliability of two fans and the reduction of Security, cause and generate instability, easily cause the potential safety hazard of generation accident.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the object of the invention is to propose a kind of two fans air duct being provided with automatic switchover air port.
Object of the present invention will be achieved by the following technical programs: preferred, above-mentioned a kind of two fans air duct being provided with automatic switchover air port, comprise the first air duct and the second air duct, air port switching part is provided with in the intersection of described first air duct and described second air duct, the baffle plate that described air port switching part comprises rotating shaft and matches with described first air duct and the second air duct, described rotating shaft is connected with drive motor, and described drive motor is connected with detector.
Preferably, the above-mentioned two fans air duct being provided with automatic switchover air port, described baffle plate can rotate in the horizontal direction around described rotating shaft.
Preferably, above-mentioned a kind of two fans air duct being provided with automatic switchover air port, described detector is located in described first air duct and described second air duct.
Outstanding effect of the present invention is: the movement 1) driving baffle plate by adding special driving power, can ensure flexibility and the promptness of baffle plate movement; 2) baffle plate moves in the horizontal direction under the drive of rotating shaft, is different from vertical direction and moves and need to overcome distinguished and admirable resistance, be more conducive to the mobile promptness of baffle plate; 3) detector is set in air duct, can by the real-time detection case of detector, the movement of regulating fender, is different from the judgement by manually doing out movement, can break down in time to the semi-finished product cooling in course of working.
Below just accompanying drawing in conjunction with the embodiments, is described in further detail the specific embodiment of the present invention, is easier to understand, grasp to make technical solution of the present invention.
Accompanying drawing explanation
Fig. 1 is the structural representation of two fans air duct.
Embodiment
As shown in Figure 1, above-mentioned a kind of two fans air duct being provided with automatic switchover air port of the present embodiment, comprise the first air duct 1 and the second air duct 2, air port switching part is provided with in the intersection of the first air duct 1 and the second air duct 2, the wherein air port switching part baffle plate 4 that comprises rotating shaft 3 and match with the first air duct 1 and the second air duct 2, rotating shaft 3 is connected with drive motor 6, and drive motor 6 is connected with detector 5.Detector 5 is located in the first air duct 1 and the second air duct 2.By the drive motor 6 arranging baffle plate 4 and match, can ensure to switch the air port of two fans timely.
Wherein, baffle plate 4 rotates in the horizontal direction around rotating shaft 3, and due to the shape of baffle plate 4 identical with the shape in air port, can keep good sealing with air port, be compared to the movement at vertical direction, the moving resistance of substantially horizontal is less, and flexibility is stronger.
Need to switch air port when detector 5 detects that this air duct breaks down, or cool complete need switch air port time, instruction can be sent to drive motor 6, indicate it to rotate, thus drive rotating shaft 3 to rotate, baffle plate 4 will be moved in the horizontal direction, blocks and open air port, completes the operation switching air port.
The present invention still has numerous embodiments, all employing equivalents or equivalent transformation and all technological schemes formed, and all drops within protection scope of the present invention.
Claims (3)
