Protective device and electric meter box

Abstract

The invention provides a protective device and an electric meter box and relates to the technical field of electric meter boxes. The protective device comprises a shell, a fixed protective baffle, a movable protective baffle, a sealing strip and a movable rotary shaft. A first opening is formed in the upper portion of the shell, the fixed protective baffle obliquely covers the first opening, and a second opening is formed below the first opening. The movable protective baffle is arranged on the second opening, one end of the movable protective baffle is movably connected with the shell through a movable rotary shaft, and the other end of the movable protective baffle extends out of the second opening. In the reset state, the movable protective baffle is closely attached to the fixed protective baffle through the sealing strip, and when the protective device is opened, the movable protective baffle is rotated to be in a horizontal state. By means of cooperation of the fixed protective baffle and the movable protective baffle, the electric meter box is prevented from being exposed in the outside environment for a long time, rainwater and dust are effectively prevented from entering the electric meter box, damage of work components is reduced, and accordingly loss of users is reduced.

Description

Technical field [0001] The invention relates to the technical field of electric meter boxes, in particular to a protective device and an electric meter box. Background technique [0002] As a commonly used electrical instrument equipment, the electric meter box is widely used in power lines. At the same time, the electric meter box is an intelligent device that has certain requirements for the temperature and humidity of the working environment. In real life, especially in rural areas, the meter box is often installed outdoors, so that the meter box is exposed to the outside environment for a long time. Rain and dust can easily enter the meter box, causing damage to working components and causing losses to users. [0003] In China, most electric meter boxes used in most areas are made of plastic or plastic steel materials. After a period of installation and use, due to artificial opening, wind and sun, etc., weak cracks will occur in the door and box body. , Most of the meter boxe...

AI Technical Summary

Problems solved by technology

In real life, especially in rural areas, the meter box is often installed outdoors, so that the meter box is exposed to the external environment for a long time. Rainwater and dust can easily enter the inside of the meter box, causing damage to the working components and causing losses to users.

[0003] In my country, the meter boxes used in most areas are mostly made of plastic or plastic steel. After being installed and used for a period of time, due to various reasons such as artificial opening, wind and sun, weak cracks will occur on the box door and box body. , Most of the meter boxes installed outdoors do not have effective rainproof measures. In rainy days, especially in continuous rainy weather, rainwater can easily flow into the box along the top of the box cover, causing damage to the protection switch and other faults. Therefore, the power supply must be repaired or replaced to restore power. , which not only wastes manpower and material resources but also affects the normal power consumption of users

[0004] Aiming at the problem that the above-mentioned electric meter box is damaged due to the influence of the environment during outdoor use, which in turn affects the normal electricity consumption of users, no effective solution has been proposed yet.
