Description

Waterproof and dustproof electromechanical device protective shell

Technical Field

The invention belongs to the technical field of electromechanical equipment, and particularly discloses a waterproof and dustproof electromechanical equipment protective shell.

Background

With the continuous improvement of the living standard of people, people have more and more demands on electromechanical equipment in daily life, and the electromechanical equipment from vehicles to various household appliances, computers, printers and the like becomes indispensable electromechanical products in the life of people. Electromechanical equipment belongs to precision instruments, and in order to ensure normal operation and work under severe outdoor environments such as temperature, humidity, solar radiation, sand wind, rain and the like, the electromechanical equipment needs to be placed in a box body or a cabinet body or other protective shells with waterproof and dustproof functions.

Most of the protection shells of the existing electromechanical devices are single-layer metal sheets, and in order to reduce the internal temperature, a ventilation opening is generally arranged on a shell to dissipate heat and ventilate. However, once the outdoor equipment meets rainy and snowy weather, rain, dust and the like can enter the protective shell from the ventilation opening under the action of wind power, so that potential safety hazards are brought to the reliable operation of the internal electromechanical equipment; meanwhile, rainwater is easy to accumulate in the protective shell, and if the rainwater is not discharged in time, equipment is easy to be short-circuited, so that the normal use of the equipment is influenced; in addition, because the air temperature is high in summer and the metal temperature is low, water vapor in the air is easily condensed into small water drops in the metal shell due to temperature difference, and the small water drops are easy to cause short circuit of the equipment when dropping on the equipment.

Disclosure of Invention
