Embodiment 1

[0032] like Figure 1-4 Shown, a kind of decontamination device that is used for fan air inlet net cover, comprises rotating blade 1 and blade base 2 and rotating shaft 8, and described rotating blade 1 is fixedly connected with blade base 2; Described blade base 2 and The rotating shaft 8 is fixedly connected, and the way of fixed connection can be welding, bonding or integral molding.

[0033] Concretely, the rotary blade 1 of the decontamination device used for the fan air inlet net cover is arc-shaped as a whole, and has a certain thickness, and the inner arc side of the arc-shaped rotary blade 1 is the wind-receiving surface A (such as figure 2 shown), the wind-receiving surface A is used to drive the rotating blade 1 to rotate under windy conditions (the windy condition refers to the condition that the fan starts and the wind enters the fan from the outside), and the specific wind-receiving surface is as a whole Inclined, and the wind-receiving surface is inclined to t...

Embodiment 2

[0046] like Figure 5 As shown, a new type of fan is provided with the decontamination device for the fan air inlet grille in Embodiment 1 on the outside of the fan air inlet grille 3 .

[0047] Specifically, the bottom surface of the rotating blade 1 of the decontamination device is close to the net cover 3, and does not contact the net cover 3. The purpose of setting like this is that the distance between the rotating blade 1 and the net cover 3 is smaller, and the dust on the net cover 3 that is removed The smaller the garbage attachment, the better the decontamination effect, and the rotating blade 1 is not in contact with the net cover 3, which can reduce the resistance, and the smaller the resistance, the faster the rotating speed.

[0048] In the present invention, the airflow of the air inlet of the fan drives the rotating blade 1 of the decontamination device used for the air inlet net cover of the fan to rotate, and the working states of the two are consistent. Afte...

Embodiment 3

[0051] A method for decontaminating the grille of the air inlet of a fan. The decontamination device for the grille of the air inlet of the fan described in Embodiment 1 is arranged on the outside of the grille of the air inlet of the fan. Specifically, after the fan is turned on, through the The wind drives the rotating blade 1 of the decontamination device to rotate, and the rotating rotating blade 1 completes the removal of dirt on the surface of the net cover 3 .

Abstract

The invention relates to a decontamination device for a fan air inlet mesh enclosure, a fan and a fan mesh enclosure decontamination method. The decontamination device comprises a rotating blade, a blade base and a rotating shaft, wherein the rotating blade is fixedly connected with the blade base; the blade base is fixedly connected with the rotating shaft, the whole rotating blade is in an arc shape, the inner arc side of the arc-shaped rotating blade is a wind receiving face, and the wind receiving face is used for driving the rotating blade to rotate under the condition that the fan is started. The decontamination device for the fan air inlet mesh enclosure can be directly and conveniently installed on the fan mesh enclosure, so that the decontamination effect can be achieved after the decontamination device is installed on the fan mesh enclosure, and the cost is low.

Description

technical field [0001] The invention relates to the field of fans, in particular to a decontamination device for a net cover of an air inlet of a fan, a novel fan and a method for decontaminating the net cover of an air inlet of a fan. Background technique [0002] Every spring catkins and catkins fly. In rail transit fan equipment, a large amount of poplar, catkins, and large particles of garbage will accumulate on the outer surface of the fan air inlet grille, resulting in blockage of the fan air intake, reducing the air intake of the fan, and affecting the heat dissipation of the equipment in the vehicle. In order not to affect normal driving, large particles of garbage such as poplars, catkins, and leaves attached to the outer surface of the fan air inlet grille need to be cleaned up in time. At present, there is no suitable and convenient decontamination solution. The existing method is manual cleaning at certain intervals, which is time-consuming and labor-intensive. ...
