Abstract

The utility model discloses a novel waterproof and dustproof power distribution cabinet. The power distribution cabinet is composed of a cabinet body (1), a ventilation opening (2), a waterproof and dustproof cover A (3) and so on. The power distribution cabinet is characterized in that the lower part of the back of the cabinet body (1) is provided with the ventilation opening (2), the inner side of the ventilation opening (2) is provided with the waterproof and dustproof cover A (3) slightly bigger than the ventilation opening (2), the waterproof and dustproof cover A (3) is fixed on the cabinet body (1), and a filter screen (4) matched with the size of the ventilation opening (2) is fixed in the ventilation hole (2). A downward blind window (7) is externally provided with a metal woven mesh (8), which can prevent big objects from falling into the blind window (7) and damaging the other elements inside; and a waterproof and dustproof cover B (5) and the blind window (7) are located at different altitudes, therefore, the amount of dust falling into the waterproof and dustproof cover B (5) is further reduced.

Description

The new waterproof power distribution cabinet that prevents dust

Technical field

The utility model relates to a kind of power distribution cabinet, relates in particular to the dustproof power distribution cabinet of a kind of new waterproof.

Background technology

Generally devices such as a large amount of thermal relays, circuit breaker, capacitor are installed all in the power distribution cabinet, these devices in use can produce a large amount of heats; If the heat that produces can not in time distribute, just possibly burn these devices, even cause the blast of power distribution cabinet, produce serious consequence, so power distribution cabinet generally all is equipped with radiator structure.In actual production, the workshop condition of factories such as shipyard, textile mills is general relatively more abominable, and the power distribution cabinet in the workshop usually is in the environment of moist many dirt, often needs higher water proof and dust proof grade.The radiator structure of power distribution cabinet has just become the difficult point of water proof and dust proof, and common on the market power distribution cabinet water proof and dust proof ability is often not ideal enough.

Summary of the invention

In order to solve the problems of the technologies described above; The utility model provides the good new waterproof of a kind of waterproof and dustproof performance power distribution cabinet that prevents dust; Be made up of cabinet (1), ventilating opening (2), water proof and dust proof cover A (3), screen pack (4), water proof and dust proof cover B (5), dividing plate (6), shutter (7), metal knitted net (8), it is characterized in that the cabinet lower backside is provided with ventilating opening, the ventilating opening inboard is provided with the water proof and dust proof cover A that is slightly larger than the ventilating opening size; Water proof and dust proof cover A is fixed on the cabinet; The ventilating opening internal fixation has a screen pack that is complementary with the ventilating opening size, and the ventilating opening arranged outside has the water proof and dust proof cover B that is slightly larger than the ventilating opening size, and water proof and dust proof cover B is fixed on the cabinet; Water proof and dust proof cover B is outside equipped with the dividing plate that is fixed on the cabinet; Its underpart is provided with shutter, and the position that is provided with of the shutter on water proof and dust proof cover B and the dividing plate forms high low head, and the shutter external fixation has metal knitted net.

The beneficial effect of the utility model is: downward shutter adds metal knitted net outward, can prevent that the object of bulk from getting into shutter, damages inner other devices; The position of water proof and dust proof cover B and shutter has high low head, has further reduced the quantity of the dust that gets into water proof and dust proof cover B; Hydrone and the dust of water proof and dust proof cover in can filtered air, screen pack can absorb, hydrone and dust in the filtered air, has adopted water proof and dust proof cover A, water proof and dust proof cover B and screen pack triplen, has significantly improved the water proof and dust proof performance of rack.

Fig. 2 is the device enlarged drawing of the utility model.

Embodiment

According to Fig. 1, shown in Figure 2, be provided with a ventilating opening (2) in the lower backside of rack (1), a screen pack (4) that is complementary with ventilating opening (2) size is arranged in the ventilating opening (2), screen pack (4) can absorb, hydrone and dust in the filtered air; The both sides of ventilating opening (2) are respectively equipped with water proof and dust proof cover A (3) and water proof and dust proof cover B (5); Water proof and dust proof cover A (3) is all identical with size, the shape of water proof and dust proof cover B (5); And, have hydrone and the effect of dust in the filtered air all through being bolted on the cabinet; Water proof and dust proof cover B (5) is outside equipped with through being bolted to the waterproof bulkhead (6) on the cabinet; The bottom of waterproof bulkhead (6) is a downward shutter (7), can prevent to get into shutter (7) from top next dust, and shutter (7) has high low head with the position of water proof and dust proof cover B (5); Can further prevent the entering of dust; Shutter (7) outside weld is a metal knitted net (8) then, can prevent effectively that the solid of bulk from getting into shutter (7), damages other devices of the inside.

The position of devices such as the described ventilating opening of above embodiment can be arranged on any position of rack.
