A kind of aeration structure of hypervelocity platform
Technical field:
The utility model is related to a kind of aeration structures of hypervelocity platform.
Background technology:
The ventilating duct of existing hypervelocity platform host is that air port is irised out in processing one on the outer wall of casing, and by exceeding the speed limit, platform host turns
Cooling fan cooling on son, cooling air-flow are only cooled to inside host, the protective cover not being cooled to outside hypervelocity platform host,
Cooling range is not wide enough (such as Fig. 1).
Utility model content:
The utility model is to provide a kind of aeration structure of hypervelocity platform to solve the above-mentioned problems of the prior art.
Technical solution used by the utility model has:A kind of aeration structure of hypervelocity platform, including hypervelocity platform host, protection
Cover and lid, the protective cover are fixed in hypervelocity platform host on the upper surface of casing, and cover cap further includes together on protective cover
Separate terminal enclosure, pipeline, valve, air blower and dust cover, the separate terminal enclosure are fixed on the lower face of the casing, and the one of pipeline
End is connected with separate terminal enclosure, and the air outlet of the other end and air blower is tightly connected, and valve is connected on pipeline;In the casing
Upper surface is equipped with air outlet, and lower face is equipped with air inlet, and dust cover is fixed on the upper surface of the casing, and dust-proof
Ventilation gap is formed between cover board and casing upper surface, ventilation gap connects with air outlet, and separate terminal enclosure is by air inlet and surpasses
Chassis cavity connects in fast platform host.
Further, the center of circle direction of the dust cover lower face is equipped with positioning groove, in dust cover lower face
Circumferencial direction on be evenly equipped with several radiating grooves, several threaded holes are evenly equipped on the upper surface of dust cover.
Further, the upper surface of the casing of the hypervelocity platform host is equipped with lug boss, and air outlet is set to the lug boss
On, lug boss stretches in the radiating groove.
The utility model has the advantages that:
1) cooling vent on hypervelocity platform casing periphery is arranged to casing upper surface the utility model, facilitates sealing, cold
Cooling air-flow will can all cool down in host and protective cover when but;
2) cooling vent (air outlet) is arranged on casing upper surface, and when the platform host work that exceeds the speed limit vacuumizes or host is cold
When but, keep in the conduction state between protective cover inside host, air-flow is flowed through from cooling vent, will not be from hypervelocity platform host
Upper angular contact bearing gap in flow through because air-flow can bring dust adsorption on angular contact bearing lubricating grease, and air-flow
The lubricating grease on angular contact bearing may be blown off, bearing service life is influenced;
3) dust cover in the utility model is while ensureing to divulge information, and can be effectively prevented extraneous dust and enter
It exceeds the speed limit in platform host, using effect is good.
Description of the drawings:
Fig. 1 is the ventilating and cooling schematic diagram of hypervelocity platform host in the prior art.
Fig. 2 is the utility model structure chart.
Fig. 3 is structure chart of the dust cover in fast platform host on casing in the utility model.
Fig. 4 is the structure chart of dust cover in the utility model.
Specific implementation mode:
The utility model will be further described below with reference to the accompanying drawings.
As shown in Figures 2 to 4, the utility model discloses a kind of aeration structure of hypervelocity platform, including hypervelocity platform host 1, anti-
Shield 13, lid 12, separate terminal enclosure 14, pipeline 16, valve 17, air blower 18 and dust cover 2, protective cover 13 are fixed on hypervelocity
In platform host 1 on the upper surface of casing, lid 12 is covered on protective cover 13, and separate terminal enclosure 14 is fixed on the lower face of the casing
On, one end of pipeline 16 is connected with separate terminal enclosure 14, and the air outlet of the other end and air blower 18 is tightly connected, and valve 17 is connected to
On pipeline 16.Air outlet 100 is equipped on the upper surface of casing in the platform host 1 that exceeds the speed limit, lower face is equipped with air inlet 200, prevents
Dirt cover board 2 is fixed on by screw on the upper surface of casing, and forms ventilation gap between dust cover 2 and casing upper surface
300, ventilation gap 300 connects with air outlet 100, and separate terminal enclosure 14 passes through air inlet 200 and chassis cavity in hypervelocity platform host 1
It connects.
The center of circle direction of 2 lower face of dust cover in the utility model is equipped with positioning groove 21, the positioning groove 21
Convenient for location and installation of the dust cover 2 on casing.Several threaded holes 23, screw thread are evenly equipped on the upper surface of dust cover 2
It is worn in hole 23 and connects screw, dust cover 2 is fixed on hypervelocity platform host 1.
To prevent preferably dust-proof radiating effect, several heat dissipations are evenly equipped on the circumferencial direction of 2 lower face of dust cover
The upper surface of slot 22, the casing of hypervelocity platform host 1 is equipped with lug boss 11, and air outlet 100 is set on the lug boss 11, protrusion
Portion 11 stretches in the radiating groove 22.
When needing to cool down hypervelocity platform, lid 12 is opened, then opens valve 17 and air blower 18, cooling wind is logical
It crosses air inlet 200 to enter in hypervelocity platform host 1, hypervelocity 1 internal part of platform host be cooled down, then cooling wind is again by going out
Air port 100 enters in protective cover 13, is cooled down to protective cover 13.
Dust cover 2 in the utility model can be effectively prevented extraneous dust and enter while ensureing to divulge information
It exceeds the speed limit in platform host 1, using effect is good.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
It for art personnel, can also make several improvements without departing from the principle of this utility model, these improvement also should be regarded as
The scope of protection of the utility model.
