Problems solved by technology

[0002] Distribution box is assembled in closed or semiclosed metal safe by electrical wiring requirement by switchgear, measuring instrument, protective device and auxiliary equipment or on screen width, forms low-voltage distribution equipment, can connect with manual or automatic switch during normal operation. Open or break the circuit, cut off the circuit or alarm with the help of protective electrical appliances in case of failure or abnormal operation, use the measuring instrument to display various parameters in operation, and adjust some electrical parameters to prompt or send out deviations from normal working conditions Signals are often used in various power generation, distribution, and substations. The normal operation of the distribution box ensures the continuity and safety of power supply. In areas with severe wind and sand, the general distribution box can not quickly Good protection against wind and sand erosion
[0003] In the existing technology, there is a problem that the distribution box is easy to enter the wind and sand in the area with a lot of wind and sand, which will cause the phenomenon that the sand is easy to enter the circuit, and finally lead to insufficient power supply and damage to the distribution box.

Abstract

The invention discloses a sand-proof distribution box in the technical field of distribution boxes, which comprises a distribution box body, a distribution box cavity is formed in the front end surface of the distribution box body, a through groove is formed in the inner end of the distribution box cavity, a ventilation groove is formed in the inner side of the through groove, a side connecting block is fixedly connected to the inner end surface of the distribution box cavity, and a sliding groove is formed in the front end surface of the side connecting block. A first opening groove is formed in the inner end face of the sliding groove, a second opening groove is formed in the inner end face of the first opening groove, a connecting spring is fixedly connected to the inner end face of the first opening groove, a connecting column is fixedly connected to the outer end of the connecting spring, and a drawing column is fixedly connected to the inner end face of the connecting column; through the arrangement of the passing groove, the side connecting block, the sliding groove, the first opening groove, the second opening groove, a connecting spring, a connecting column, a drawing column, a sliding block, a connecting hole and a filter screen, the action of wind and sand protection and blocking on the inner cavity of the power distribution box can be completed, and the effect that the power distribution box body can operate for a long time is achieved.

Description

technical field [0001] The invention relates to the technical field of distribution boxes, in particular to a wind and sand-proof distribution box. Background technique [0002] The distribution box is a low-voltage power distribution device that assembles switchgear, measuring instruments, protective appliances and auxiliary equipment in a closed or semi-closed metal cabinet or screen according to the electrical wiring requirements, and can be connected by manual or automatic switches during normal operation. Make or break the circuit, cut off the circuit or give an alarm with the help of the protective device when there is a fault or abnormal operation, and use the measuring instrument to display various parameters in operation, and can also adjust some electrical parameters to prompt or issue a deviation from the normal working state. Signals are often used in various power generation, distribution and substations. The normal operation of the distribution box ensures the ...
