Abstract
The invention relates to a high-sensitivity rainproof and windproof distribution box. The distribution box comprises a responding mechanism and a closing mechanism. The responding mechanism comprises a floating bucket connected with a collecting bucket. A floating mechanism is arranged in the floating bucket and drives the closing mechanism to start under action of the buoyancy force of wind or water. The closing mechanism comprises two ventilation plates which are mutually shielded or overlapped so that the interior and the exterior of the distribution box can be opened or closed annularly. Through the high-sensitivity responding structure, the distribution box can quickly make a response when encountering high wind or heavy rain; the distribution box can be closed through mutual sliding of the movable ventilation plate and the fixed ventilation plate, so that dust, impurities and rainwater are prevented from entering the distribution box; during good weather, a ventilation channel between the fixed ventilation plate and the movable ventilation plate is opened, and therefore good cooling, ventilation and drying properties are guaranteed.
Description
Technical field
The present invention relates to a kind of high sensitivity flashing, wind proofing distribution box, specifically a kind of reaction mechanism for detecting distribution box ambient weather environment.
Background technology
Distribution box is assembled in closed or semiclosed metal safe by electrical wiring requirement by switchgear, measuring instrument, protective device and auxiliary equipment or shields on width; the low-voltage distribution equipment formed; can connect or point deenergizing by manual or automatic switch during normal operation; circuit or warning is cut off by protective device when fault or irregular operating; operating various parameter can be shown by means of measuring instrument; also can adjust some electric parameter; point out departing from normal operating conditions or send signal, being usually used in each, joining, in electric substation.Existing distribution box needs mostly in outdoor application, the casing of distribution box is placed directly on ground usually, ventilation rainproof function is bad, when humidity or rainy weather, rainwater easily infiltrates in distribution box, cause the electric component short circuit in distribution box, damage, affect the normal use of distribution box, when strong wind weather, strong wind is easy to can by leaf, the impurity such as dust are blown in distribution box, these impurity are once increase, be easy to the short circuit or the burning that cause distribution box, at present, the top cover of major part distribution box is still slab construction, be unfavorable for the discharge of rainwater, along with the serviceability temperature of distribution box can raise gradually, the easy like this box equipment that makes damages, ventilation hole is used even if having, the impact of rainwater and dust is not considered yet, electrical equipment can be made impaired, and existing distribution box is also not easy to mobile, very flexible, usually lifted by people time mobile, very inconvenient, the operational environment of constantly change can not be adapted to, casing is opaque, the situation of each element in inside is not observed,
