Rotatable waterproof electric power meter

Abstract

The invention provides a rotatable waterproof electric power meter, which comprises a meter box, wherein the meter box comprises an upper box cover and a lower box body, a seal ring is fixed to a connection part of the upper box cover and the lower box body, locating blocks are arranged on the inner wall of the lower box body, a protruded annular plate is fixed to the interior of the upper box cover, and locating grooves are formed in the annular plate and are clamped with the locating blocks; a rotary base is fixedly connected with the bottom end of the meter box, and a bearing rotating assembly is fixed to one end of the rotary base; and a windshield wiper is fixed to one side, on which a display screen is arranged, of the meter box. Due to the locating blocks and the locating grooves arranged in the upper box cover and the lower box body, the upper box cover and the lower box body are closely connected, and meanwhile, the seal ring is fixed to the connection part of the upper box cover and the lower box body, thereby further achieving a waterproof effect; the rotary base is mounted at the bottom end of the lower box body so that the box body can rotate, which helps the observation and maintenance personnel to regulate angles; and the windshield wiper can automatically clean water stains on the display screen so that the meter is convenient to observe and read.

Description

technical field [0001] The invention relates to the field of electric meters, in particular to an electric meter, in particular to a rotatable waterproof electric meter. Background technique [0002] Power meters are power measurement and control equipment that provide solutions for power parameter measurement, power quality monitoring and analysis, and electrical equipment control. As an advanced intelligent and digital front-end acquisition component of the power grid, power meters have been widely used in various control systems, SCADA systems and energy management systems, substation automation, community power monitoring, industrial automation, intelligent buildings, and intelligent power distribution cabinets , Switchgear and other equipment, it has the characteristics of convenient installation, simple wiring, and small engineering quantity.

AI Technical Summary

Problems solved by technology

[0003] Power meters are often used outdoors and in high places due to their functions. Traditional power meters have no waterproof structure, and it is very easy for water to enter in rainy days, resulting in damage to the circuits inside the meter and even causing serious consequences such as fire and leakage. Moreover, After rain or foggy weather, there are often water stains or mist on the surface of the instrument display, which is not easy to observe the readings

[0004] Because the power meter is often installed at a high place and cannot be rotated, it is inconvenient to read. At the same time, the maintenance personnel cannot rotate the power meter if they want to change the angle during maintenance. They can only move their own position, which is likely to cause danger and accidents.

[0005] In the Chinese patent application number 201720746500.9, it is proposed to protect the data display screen and operation buttons in the front half of the body from water through the outer protective shell. The precision steel mesh is blocked and does not flow in, and the remaining part of the water will be absorbed by the sponge layer, so that the water will not enter the interior of the machine and be damaged. This method mainly proposes the protection of the interior of the equipment after the water flows into the equipment. However, when the amount of water inflow is too large, this method cannot completely prevent the damage to the inside of the body, so a technical method that can directly prevent water from entering the equipment should be proposed to avoid equipment damage from the root.
