Abstract
The utility model discloses a frequency converter waterproof protection device for an elevator door motor. The frequency converter waterproof protection device is characterized in that the device comprises a frequency converter and a rainproof housing, wherein the rainproof housing comprises a bottom plate, a case body and a cover plate; the bottom plate is fixed on a door engine plate; the frequency converter is arranged on the bottom plate of the rainproof housing; vent holes are formed on the bottom plate; a heat dissipation louver is arranged on the case body; the cover plate is hinged with one end of the case body; and the other end of case body is locked. Compared with the prior art, the frequency converter is fixed inside the rainproof housing; the rainproof housing has simple structure and can be conveniently opened and locked; the frequency converter is convenient in installation and commissioning; and meanwhile, through the vent holes arranged on the housing and the heat dissipation louver, the heat dissipation effect is good, and the waterproof protection reliability is high.
Description
Technical field
The utility model relates to the water-proof protection device of a kind of machine, belongs to the elevator technology field.
Background technology
Along with the develop rapidly of national economy, the market demand of elevator is in surge year by year.Now, elevator has become the indispensable vertical transportation instrument in building.Can elevator move safely and reliably, closely bound up with daily life.Fault rate is one of important indicator of weighing an elevator safety reliability service.According to statistics, the fault rate about about 60% of elevator occurs in the door mechanism system at present, and frequency converter is to cause a major part of machine fault rate, therefore frequency converter is protected to reduce door machine fault rate to seem particularly important.At present the frequency converter on the door machine is general only fixes frequency converter with a base plate, and with a bending plate frequency converter is directly covered simultaneously and to be fixed on the base plate.This structure can not be carried out waterproofing protection to frequency converter by actv., and safe reliability is poor.
Summary of the invention
The objective of the invention is under the prerequisite of guaranteeing the elevator safety reliability service, opposite house machine frequency converter carries out the actv. protection.
For solving the problems of the technologies described above; the technical solution adopted in the utility model is: a kind of elevator door machine frequency converter water-proof protection device; it is characterized in that: comprise frequency converter and the rain-proof case of forming by base plate, casing and cover plate; described base plate is fixed on the machine plate, and described frequency converter is arranged on the base plate of rain-proof case.
Described base plate is provided with breather hole, and described casing is provided with louvered shutter.
Described cover plate adopts hinge to be connected with casing one end, and the other end is provided with snap close.
Compared with prior art, the utility model is fixed on frequency converter in the defence case, and rain-proof case is simple in structure; and can be easy to open and pin, the frequency converter Installation and Debugging are convenient, simultaneously; case is provided with breather hole and louvered shutter, good heat dissipation effect, waterproofing protection reliability height.
