The invention comprises the following steps:
the present invention is directed to solving the above-mentioned problems of the prior art and providing a ventilation structure of an overspeed table.
The invention adopts the technical scheme that: the utility model provides a ventilation structure of overspeed desk, includes overspeed desk host computer, protection casing and lid, the protection casing is fixed in on the up end of the casing in the overspeed desk host computer, and the lid covers on the protection casing, still includes wiring cover, pipeline, valve, air-blower and dust cover board, the wiring cover is fixed in on the lower terminal surface of casing, and one end of pipeline is linked together with the wiring cover, and the other end is connected with the air outlet seal of air-blower, and the valve is connected on the pipeline; an air outlet is formed in the upper end face of the casing, an air inlet is formed in the lower end face of the casing, the dustproof cover plate is fixed to the upper end face of the casing, a ventilation gap is formed between the dustproof cover plate and the upper end face of the casing, the ventilation gap is communicated with the air outlet, and the wiring cover is communicated with an inner cavity of the casing in the overspeed table main machine through the air inlet.
Further, a positioning groove is formed in the circle center direction of the lower end face of the dustproof cover plate, a plurality of radiating grooves are uniformly distributed in the circumferential direction of the lower end face of the dustproof cover plate, and a plurality of threaded holes are uniformly distributed in the upper end face of the dustproof cover plate.
Further, a protruding portion is arranged on the upper end face of the casing of the overspeed table main machine, the air outlet is arranged on the protruding portion, and the protruding portion extends into the heat dissipation groove.
The invention has the following beneficial effects:
1) The cooling port on the outer circular surface of the overspeed table casing is arranged on the upper end surface of the casing, so that the overspeed table casing is convenient to seal, and the host and the protective cover can be cooled by cooling air flow during cooling;
2) The cooling port (air outlet) is arranged on the upper end surface of the shell, when the overspeed platform host machine works and vacuumizes or the host machine cools, the inside of the host machine and the protective cover are kept in a conducting state, air flows through the cooling port and cannot flow through a gap of an upper angular contact bearing in the overspeed platform host machine, because the air flows can bring dust into and adsorb on the grease of the angular contact bearing, and the air flows can blow off the grease on the angular contact bearing, so that the service life of the bearing is influenced;
3) The dustproof cover plate can effectively prevent external dust from entering the host machine of the overspeed platform while ensuring ventilation, and has good use effect.
Description of the drawings:
FIG. 1 is a schematic diagram of ventilation cooling of an overspeed table host machine in the prior art.
Fig. 2 is a structural diagram of the present invention.
FIG. 3 is a block diagram of the dust cover of the present invention on the housing of the host machine.
Fig. 4 is a structural view of the dust cover plate in the present invention.
The specific embodiment is as follows:
the invention is further described below with reference to the accompanying drawings.
As shown in fig. 2 to 4, the invention discloses a ventilation structure of an overspeed desk, which comprises an overspeed desk host 1, a protective cover 11, a cover body 12, a wiring cover 14, a pipeline 16, a valve 17, an air blower 18 and a dustproof cover plate 2, wherein the protective cover 11 is fixed on the upper end face of a shell in the overspeed desk host 1, the cover body 12 is covered on the protective cover 11, the wiring cover 14 is fixed on the lower end face of the shell, one end of the pipeline 16 is communicated with the wiring cover 14, the other end of the pipeline 16 is in sealing connection with an air outlet of the air blower 18, and the valve 17 is connected on the pipeline 16. An air outlet 100 is arranged on the upper end surface of a casing in the overspeed desk host machine 1, an air inlet 200 is arranged on the lower end surface, a dustproof cover plate 2 is fixed on the upper end surface of the casing through screws, a ventilation gap 300 is formed between the dustproof cover plate 2 and the upper end surface of the casing, the ventilation gap 300 is communicated with the air outlet 100, and a wiring cover 14 is communicated with the inner cavity of the casing in the overspeed desk host machine 1 through the air inlet 200.
The lower end face of the dustproof cover plate 2 is provided with a positioning groove 21 in the circle center direction, and the positioning groove 21 is convenient for positioning and mounting the dustproof cover plate 2 on a machine shell. A plurality of threaded holes 23 are uniformly distributed on the upper end surface of the dustproof cover plate 2, and screws are connected in the threaded holes 23 in a penetrating way to fix the dustproof cover plate 2 on the overspeed table main machine 1.
In order to prevent better dustproof heat dissipation effect, a plurality of heat dissipation grooves 22 are uniformly distributed on the circumferential direction of the lower end surface of the dustproof cover plate 2, a protruding part is arranged on the upper end surface of the casing of the overspeed table main machine 1, the air outlet 100 is arranged on the protruding part, and the protruding part extends into the heat dissipation grooves 22.
