Distribution box capable of automatically closing window by gravity

Abstract

The invention relates to the technical field of distribution box rain prevention, and discloses a distribution box capable of automatically closing a window by using a gravity. The distribution box comprises a rain collecting tank, a transmission rod is interactively connected to the bottom of the rain collecting tank, a mounting seat is movably connected to the bottom of the transmission rod, a return spring is movably connected to the bottom of the mounting seat, and a pull rod is movably connected to the left side of the mounting seat. A transmission block is movably connected to the top ofthe pull rod, a buffer spring is movably connected to the left side of the transmission block, external rain and snow can fall into the rain collecting tank, a large amount of rain and snow are accumulated in the rain collecting tank at the moment, and therefore an acting force exerted on the rain collecting tank by an earth gravity is increased and transmitted into the reset spring through the transmission rod. Therefore, the reset spring is compressed to deform to drive the mounting seat to move downwards, the mounting seat moves to drive the two connecting plates to move oppositely till that the two closing plates are in contact, and the effects of automatically closing the window and preventing rainwater leakage in rainy days are achieved.

Description

technical field [0001] The invention relates to the technical field of rainproofing of distribution boxes, in particular to a distribution box that uses gravity to automatically close windows. Background technique [0002] With the development of science and technology, electricity has gradually evolved into one of the most important energy sources for people. At present, the normal life and development of human beings cannot do without the support of electricity. In order to ensure the normal operation of the city, many corners of the city are often installed There are distribution boxes for power supply in the area. [0003] The distribution box is generally set up outdoors. Since the distribution box generates a lot of heat during operation, there are often ventilation holes on the surface. This kind of ventilation hole has no automatic closing function, and there is a risk of rainwater leakage when it rains. Rainwater dripping into the distribution box can easily cause ...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a power distribution box that uses gravity to automatically close the window, which can automatically assist in accelerating the internal air flow speed in sunny days and automatically close and close the windows in rainy days to prevent rainwater leakage. Automatically clear the internal humid air to prevent it from affecting the operation of the equipment. It solves the problem that the transmission distribution box vent has no automatic closing function, there is a risk of rainwater leakage, and the problem that the internal humidity air cannot be automatically drawn out
