Abstract
The invention discloses a dustproof power distribution box and belongs to the field of power distribution boxes. The dustproof power distribution box comprises a box body and a box door hinged to the box body. The dustproof power distribution box is characterized by further comprising a box door detecting device. The box door detecting device comprises a spring switch, and a delay relay and an alarm which are disposed in the box body. The delay relay is respectively electrically connected with the spring switch and the alarm. A box body lateral wall comprises an inner wall and an outer wall. A gap is reserved between the inner wall and the outer wall. A stainless steel screen for preventing dust is disposed on the inner wall. A plurality of strip-shaped ventilation holes for radiation are formed in the outer wall. An air outlet is formed in the lower portion of the outer wall. A fan is disposed at the air outlet. The dustproof power distribution box adopting the double-layer wall structure has the advantages that dust can be well prevented, and an alarm can be given out when the box door is opened for a long time to remind an inspector to close the box door so as to prevent dust deposition in the box.
Description
Technical field
The present invention relates to distribution box field, in particular to a kind of dustproof distributor box.
Background technology
The equipment such as switchgear, measuring instrument, protective device by electrical wiring requirement assembling is mounted with in distribution box; if accumulate a large amount of dust in distribution box; the normal use of box equipment can be affected; but existing distribution box dust tightness is bad; and attendant may forget and locks chamber door or open wide voluntarily because of electronic lock fault after having safeguarded distribution box; also can cause accumulation dust in case, therefore need now a kind of distribution box that can solve the problem badly.
Summary of the invention
The object of the present invention is to provide a kind of dustproof distributor box, to solve the bad problem of existing distribution box dust tightness.
For realizing the object of the invention, the technical scheme adopted is: a kind of dustproof distributor box, comprise casing and the chamber door hinged with casing, it is characterized in that, also comprise chamber door checkout gear, chamber door checkout gear comprises snap switch, be arranged at time-delay relay in casing and siren, and time-delay relay is electrically connected with snap switch and siren respectively; Wall box is made up of inner and outer wall, has gap between inner and outer wall, and inwall is arranged the stainless steel guard with dustproof effect, outer wall is provided with the some bar shaped ventilation holes for dispelling the heat, outer wall bottom is provided with air outlet, and air outlet place is provided with blower fan.
Further, casing is provided with groove, is provided with snap switch in groove; Chamber door edge is provided with shielding plate, and shielding plate is provided with projection, and when the door is in a closed position, projection embeds in groove.
The invention has the beneficial effects as follows, sidewall adopts double-decker, when the dust in outside air is entered in the gap of outer wall and inwall by bar shaped ventilation hole, blower fan can be extracted out, avoid it to enter box house, there is dust tightness well, also improve distribution box thermal diffusivity simultaneously; In addition when chamber door is not closed for a long time, time-delay relay can start siren and sound the alarm, and reminds related personnel's walkaround inspection and closes upper chamber door, avoids accumulation dust in case.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Also by reference to the accompanying drawings the present invention is described in further detail below by specific embodiment.
Fig. 1 shows dustproof distributor box provided by the invention, comprise casing 1 and the chamber door 14 hinged with casing 1, it is characterized in that, also comprise chamber door checkout gear, chamber door checkout gear comprises snap switch 3,8 and the siren 7 be arranged in casing 1, and time-delay relay 8 is electrically connected with snap switch 3 and siren 7 respectively; In order to make chamber door 14 and casing 1 can close contact, casing 1 be provided with groove 2, is provided with snap switch 3 in groove 2, and chamber door 14 edge is provided with shielding plate 13, shielding plate 13 is provided with projection 12; When chamber door 14 closes, projection 12 embeds in groove 2, and withstand the snap switch 3 in groove 2, now time-delay relay 8 is in off-position; When chamber door 14 is opened, projection 12 departs from groove 2, snap switch 3 is upspring, now time-delay relay 8 is in "on" position, start timing, if chamber door 14 is not closed at the appointed time, then time-delay relay 8 starts siren 711 and sounds the alarm, remind patrolman to close chamber door 14, avoid dust stratification in case.
Further, casing 1 sidewall is made up of inwall 10 and outer wall 4, gap is had between inwall 10 and outer wall 4, inwall 10 is arranged the stainless steel guard 9 with dustproof effect, outer wall 4 is provided with the some bar shaped ventilation holes 5 for dispelling the heat, outer wall 4 bottom is provided with air outlet 11, air outlet 11 place is provided with blower fan 6, when the dust in outside air to enter outer wall 4 and the gap of inwall 10 by bar shaped ventilation hole 5 in, blower fan 6 can be extracted out, avoids it to enter casing 1 inner.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
