Abstract
The utility model concretely discloses a fan water-proof cage device of a small outdoor ONU box, belonging to the ONU box technical field, comprising a water-proof cage shell, a bend type dust removal device in the water-proof cage shell, wherein the top of the bend type dust removal device is respectively mounted on the brim of the water-proof cage shell and two edges of the bend type dust removal device are respectively adhered on the two side wall surfaces of the water-proof cage shell. After assembling the fan water-proof device, a fan outlet assembled on the small outdoor ONU box provides the IPX5 water-proof level for the box. When the fan is working, the air from the fan makes the bend type dust removal device from the fan outlet, so as to ensure the radiation effect of the box; when the fan is not working, the dust removal device is opened to cover the fan outlet of the fan due to the self-gravity, thus the dust-removal level achieves the self-protection level of the dust removal device. The ventilation radiation function of the fan and the dust removal function of the dust removal net are effectively combined with strong practicability.
Description
Technical field
The utility model belongs to ONU casing technical field, has been specifically related to a kind of fan water proof cover device of small-sized outdoor ONU casing.
Background technique
Existing small-sized outdoor ONU casing generally adopts fan to carry out ventilation and heat.Wherein fan adopts temperature control element to control, when temperature is higher in the casing (mainly being summer), and temperature control element control fan work; Arrived temperature in chassis lower the time (particularly winter), fan will quit work.Simultaneously, autumn and winter are dry, blow through regular meeting, cause the situation of outdoor normal generation airborne dust.At present, known small-sized outdoor ONU casing fan outlet all has water proof cover and fan guard.Fan guard is effective in order to make the ventilation fan amount, often adopt the large opening form, and water proof cover also only plays waterproofing effect, can make fan and cabinet inside laying dust, so just is difficult to satisfy simultaneously ventilation and heat and dust-tight requirement.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of fan water proof cover device of small-sized outdoor ONU casing is provided, in case fan work, the wind energy that fan produces enough will adopt the folding type dust guard of lightweight material to blow open, reach the effect of ventilation and heat; When fan did not need work, dust guard can be covered with exhaust outlet, reached the dustproof effect of dustproof reticular structure nominal, thus this device can be effectively in conjunction with the dustproof effect of the ventilation and heat of fan and Air Filter in one, practical.
In order to realize above-mentioned technical purpose, the utility model is realized by following technological scheme:
The fan water proof cover device of a kind of small-sized outdoor ONU casing described in the utility model, comprise the water proof cover housing, in the described water proof cover housing folding-tortuous type dust guard is installed, the top correspondence of described folding-tortuous type dust guard is installed on the brim of a hat of water proof cover housing, and the both sides of described folding-tortuous type dust guard are fitted in the two side walls of water proof cover housing accordingly.
In the utility model, described folding-tortuous type dust guard is to be made by lightweight material, and it comprises frame and the middle reticular structure that places the edge.
Further improvement as above-mentioned technology, described folding-tortuous type dust guard comprises two-part up and down, wherein upper half part area is less than lower half portion area, and snapping together by annular junction button activity between the upper and lower half is divided, because the folding-tortuous type dust guard is movable snapping together, make that upper half part of folding-tortuous type dust guard is subjected to the restriction of wind-force and water proof cover inner walls simultaneously, is opened into several angle when fan work; Lower half portion is subjected to the effect of wind-force, water proof cover inner walls and annular junction button, is close to outer casing inner wall, plays ventilation and heat effect preferably, has certain dustproof effect simultaneously; And when fan is idle, because lower half portion area and the quality of folding-tortuous type dust guard are bigger, owing to the effect of self gravitation and annular junction button, whole folding-tortuous type dust guard is closed into plumbness simultaneously, be close to exhaust outlet, have dustproof and waterproof effect preferably.
In the utility model,, be filled with the sealing waterproof adhesive tape between the described water proof cover housing the brim of a hat and the ONU box outer surface in order to realize water proofing property.
Prior art is compared, and the beneficial effects of the utility model are:
(1) the fan water proof cover device of the described small-sized outdoor ONU casing of model utility can reach certain proofing dust and protecting (protection class can be decided according to reticular structure) when fan is idle, in addition, it can also be when fan work, satisfy the heat radiation needs of ONU casing, contradiction reunification between solving in the prior art heat radiation effectively and preventing dust, practicability is good;
(2) water proof cover apparatus structure described in the utility model is simple, installs easily, and in light weight, volume is little, and is cheap.
