Technical Field

The present invention relates to an electric power equipment, more specifically, it relates to a manually operated mechanism box of a drainable and moisture-proof isolating switch.

Background

The manual operating mechanism box of the isolating switch is exposed outdoors for a long time, and rainwater permeates into the interior of the box body to form accumulated water and cannot be discharged. In addition, the mechanism case is subject to moisture attack, which tends to cause the mechanism case to be excessively humid. The accumulated water and the moisture are too heavy, so that the corrosion of wiring joints, terminal blocks and the like in the mechanism box is aggravated, the condition of short circuit or grounding of a loop is caused, and the safety and the stability of a power grid are seriously threatened. An exhaust seat is usually arranged on a box of the existing manual operating mechanism of the isolating switch, as shown in figures 1 and 2, but the exhaust seat is difficult to drain away liquid accumulated water. Some isolator manual operation mechanism casees have installed the heater additional on the market, make the inside moisture evaporation that accelerates of mechanism case, nevertheless because lack exhaust hole or exhaust hole position are improper, lead to vapor to be difficult to smoothly discharge, and the dehumidification effect is not obvious. The utility model with the publication number of CN209298629U is specially favorable for 2019, 8 and 23, and discloses a dehumidifying device for an electric cabinet, which comprises a cabinet body, wherein supporting legs are fixedly connected to four corners of the bottom of the cabinet body, a heating cavity is arranged at the bottom of an inner cavity of the cabinet body, a heat conducting pipeline is connected to the heating cavity, air nozzles are uniformly arranged on the heat conducting pipeline, air vents are arranged at two sides of the cabinet body, a mounting plate is fixedly connected to the cabinet body, a protective cover is arranged at the outer side of the mounting plate, a connecting hole is fixedly connected to the protective cover, the connecting hole is fixed at the rear side of the inner cavity of the cabinet body through a fixing bolt, a first fan is arranged at the top of the protective cover, and ventilating ducts are symmetrically arranged at two sides of the top end of the cabinet body. The condensed water is discharged through the water guide pipe, so that the cabinet is convenient and practical, and the moisture in the cabinet body can be effectively removed. However, the invention dehumidifies by means of water vapor condensation, has a complex structure and no reasonable airflow channel, and water vapor is difficult to directly discharge due to the fact that the form of the water vapor needs to be changed, so that the dehumidification effect is influenced, and the manufacturing cost is greatly increased.

Disclosure of Invention

The invention provides a manual operating mechanism box of an isolating switch, which is simple in structure, low in manufacturing cost and good in dehumidification effect and can drain water and prevent moisture, and aims to overcome the defects that an existing manual operating mechanism box of an isolating switch is lack of a reasonable dehumidification design, is complex in structure, is difficult to discharge water vapor smoothly, and is poor in dehumidification effect and high in manufacturing cost.

The technical scheme of the invention is as follows: the utility model provides a but dampproofing isolator manual operation mechanism case of drainage, includes the box, is equipped with the exhaust seat on the box, still is equipped with drainage structures and last exhaust seat on the box, and drainage structures is located the bottom half, still is equipped with the residual water in the box and weathers the device.
