Abstract

The utility model relates to an electrical cabinet sand prevention device. With the electrical cabinet sand prevention device adopted, the problem of damage to components which is caused by large-particle sand which enters an electrical cabinet can be solved. The electrical cabinet sand prevention device comprises a fixed plate; a plurality of grooves are arranged on the fixed plate; the sections of the grooves are semicircular; a plurality of arc-shaped slots are circumferentially distributed inside each groove; accommodating holes which pass through the centers of the grooves are formed in the fixed plate; filtering cylinders are installed inside the accommodating holes; the right ends of the filtering cylinders protrude out from the inner edge surfaces of the grooves; multi-layer filter screens are mounted inside the filtering cylinders; the left end surfaces of the filtering cylinders are provided with air outlets and protrude out from the fixed plate; and the upper end and the lower end of the fixed plate are provided with connecting plates. The electrical cabinet sand prevention device of the utility model has the advantages of novel structure, excellent sand prevention effect and convenient use.

Description

A kind of Electric Appliance Cabinet sand-proof device

Technical field

The utility model relates to a kind of Electric Appliance Cabinet sand-proof device.

Background technology

The environment for use of Electric Appliance Cabinet is generally more severe, particularly in the Northwest of China, dust storm is large, some oarse-grained grains of sand are easy in ventilating opening enters cabinet under the effect of wind-force, components and parts in cabinet are caused damage, therefore, in the situation that ventilating, how to prevent that the bulky grain grains of sand from entering the problem that cabinet is the solution needed badly.

Summary of the invention

For above-mentioned situation, for overcoming the defect of prior art, the object of the utility model is just to provide a kind of Electric Appliance Cabinet sand-proof device, can effectively solve while entering the bulky grain grains of sand in existing Electric Appliance Cabinet the hurtful problem of components and parts.

The technical scheme of its solution is, comprise fixed head, have multiple grooves on fixed head, the cross section of groove is semicircle, in groove, there are the multiple deep-slotted chip breakers that are circumference uniform distribution, on fixed head, have the putting hole through groove center, be set with cartridge filter in putting hole, the right-hand member of cartridge filter stretches out the inner edge surface of groove, multiple filtration net is housed in cartridge filter, there is air outlet the left side of cartridge filter, and fixed head outside is stretched out in the left side of cartridge filter, and fixed head upper and lower side has connecting plate.

The utility model novel structure uniqueness, dustproof effect is good, easy to use.

Accompanying drawing explanation

Fig. 1 is front view of the present utility model.

Fig. 2 is the utility model and the cabinet side cutaway view while linking together.

Fig. 3 is the profile of the utility model deep-slotted chip breaker end.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further details.

Provided by Fig. 1 to Fig. 3, the utility model comprises fixed head, on fixed head 1, there are multiple grooves 2, the cross section of groove 2 is semicircle, in groove 2, there are the multiple deep-slotted chip breakers 3 that are circumference uniform distribution, on fixed head 1, there is the putting hole through groove 2 centers, in putting hole, be set with cartridge filter 4, the right-hand member of cartridge filter 4 stretches out the inner edge surface of groove 2, multiple filtration net 5 is housed in cartridge filter 4, there is air outlet 6 left side of cartridge filter 4, and fixed head 1 outside is stretched out in the left side of cartridge filter 5, and fixed head 1 upper and lower side has connecting plate 7.

In order to guarantee result of use, said deep-slotted chip breaker 3 is radiation centered by the center of circle of groove to be arranged, and the lower port of deep-slotted chip breaker has arc transition zone 8, for cushioning the impulsive force of the bulky grain grains of sand.

Said screen pack 5 is made up of the dust suction such as cloth or sponge material.

Said cartridge filter 4 is fixed on fixed head 1 by screw through sleeve 9.

The uniform arrangement on fixed head 1 of said groove 2.

The utility model is fixed on cabinet 10 through connecting plate 7, the opening of groove 2 is towards cabinet 10 outsides, in the time that wind blows to the multiple circular groove 2 on fixed head 1 with sandstone, wind is just in the interior rotation of circular groove 2, when rotated, the large granular materials such as the sand being mingled with in wind can be scraped the multiple deep-slotted chip breakers 3 in groove, when large granular materials process deep-slotted chip breaker, just can drop in deep-slotted chip breaker 3, collect through deep-slotted chip breaker, the whirlpool wind forming finally can blow to cartridge filter 4, cartridge filter 4 filters large granular materials again, the small particles material entering in cartridge filter 4 can filter through multiple filtration net 5, reach the effect that size particles material filters simultaneously, when using after a period of time, fixed head 1 entirety can be taken off and carried out maintaining from cabinet 10, wind in groove 2 is because meeting forms whirlwind, also can play the effect that strengthens wind speed, in the time of air outlet 6 air-out through filter cylinder 4, can guarantee powerful wind, play the function that the components and parts in cabinet are lowered the temperature, in multiple deep-slotted chip breakers 3, also can form wind, finally can enter in cartridge filter 4.

The utility model novel structure uniqueness, can filter large granular materials, guarantees the safety of components and parts in cabinet, also can realize the object to lowering the temperature in cabinet in sand prevention, is the innovation on power cabinet.
