Abstract
The invention discloses a movable cable tunnel ventilator which comprises a fan, a protecting screen and a screen cover. The movable cable tunnel ventilator is characterized in that the fan comprises an air duct and a fan fixing frame, the air duct is of a flaring type, a noise reducing board is arranged on the inner side of the air duct, the fan fixing frame is fixed on an upper flaring of the air duct, the protecting screen is fixed at the lower end of the air duct, a shock pad is fixed between the fixing frame and the screen cover, and two symmetrically arranged handles provided with antiskid pads are arranged on the screen cover. The movable cable tunnel ventilator integrated with the screen cover, the protecting screen and the fan can be directly placed on a cable wellhead to perform ventilation operation on the interior of the cable wellhead. The movable cable tunnel ventilator is simple in structure and highly practical.
Description
Technical field
The present invention relates to a kind of ventilator, specifically a kind of removable cable tunnel ventilator.
Background technique
As everyone knows, in cable tunnel due to for a long time in wet environment, assembled a large amount of harmful gases.In the time that cable needs repairing, must be through ventilation operation, ability G.I.H, guarantees safety of workers.Conventional cable tunnel air exchange system all adopts preserving ventilator to be fixed in special air shaft at present, and to the operation of taking a breath in cable draw pit, due to for a long time, in wet environment, ventilation system easy-to-rust or damage, cause normally working.Therefore be necessary to provide a kind of removable, the ventilator of easy-to-operat, gives cable tunnel ventilation at any time.
Summary of the invention
According to the technical problem of above-mentioned proposition, and provide a kind of removable cable tunnel ventilator.The technological means that the present invention adopts is as follows:
A kind of removable cable tunnel ventilator, comprise blower fan, protective net and square, it is characterized in that: described blower fan comprises air duct and fan fixed mount, described air duct is flared type air duct gradually, inner side at described air duct is provided with acoustic board, and described fan fixed mount is fixed in the upper enlarging of described air duct, and the lower end of described air duct is fixed with described protective net, between described fixing frame and described square, be fixed with beam, on described square, be also provided with two symmetrically arranged handles with bath mat.
Preferably, described protective net adopts stainless steel to make, and the aperture on described protective net is 5mm-15mm.
Preferably, the acoustic board that described air duct inner side arranges is polyester fibre acoustic panel.
Ventilator collection square, protective net, blower fan and the one that the present invention relates to, can directly be placed in cable wellhead to the operation of taking a breath of its inside, simple in structure, practical; The design of protective net in the present invention can prevent that larger particles from falling in ventilator, affects ventilator work, and etch-proof stainless steel has also extended the working life of this device in addition; The acoustic board design of air duct of the present invention inner side, can reduce the noise pollution that ventilator produces in the time of work greatly.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention.
In figure: 1, air duct 2, fan fixed mount 3, protective net 4, square 5, beam 6, handle
Embodiment
The invention provides a kind of removable cable tunnel ventilator, below in conjunction with accompanying drawing, technological scheme of the present invention is elaborated.
As shown in Figure 1, a kind of removable cable tunnel ventilator, comprise blower fan, protective net 3 and square 4, described blower fan comprises air duct 1 and fan fixed mount 2, described air duct 1 is flared type air duct gradually, inner side at described air duct 1 is provided with acoustic board, described fan fixed mount 2 is fixed in the upper enlarging of described air duct, the lower end of described air duct is fixed with described protective net 3, between described fixing frame 2 and described square 4, be fixed with beam 5, on described square 4, be also provided with two symmetrically arranged handles 6 with bath mat.
Described protective net 3 adopts stainless steel to make, and the aperture on described protective net 3 is 5mm-15mm.
The acoustic board that described air duct 1 inner side arranges is polyester fibre acoustic panel.
Ventilator collection square, protective net, blower fan and the one that the present invention relates to, can directly be placed in cable wellhead to the operation of taking a breath of its inside, simple in structure, practical; The design of protective net in the present invention can prevent that larger particles from falling in ventilator, affects ventilator work, and etch-proof stainless steel has also extended the working life of this device in addition; The acoustic board design of air duct of the present invention inner side, can reduce the noise pollution that ventilator produces in the time of work greatly.
The above; it is only preferably embodiment of the present invention; but protection scope of the present invention is not limited to this; any be familiar with those skilled in the art the present invention disclose technical scope in; be equal to replacement or changed according to technological scheme of the present invention and inventive concept thereof, within all should being encompassed in protection scope of the present invention.
