[0023] Example

[0024] see Figure 1-Figure 4 , the present invention provides a power box rainproof device that pulls and changes the height of the ceiling to control the switch of the cooling outlet. The ceiling 1 is arranged in the north direction of the box body 3, the controllable ceiling 1 is connected with the box body 3, the movable door 2 is movably connected with the box body 3, and the movable door handle is provided on the movable door 2 4. The movable door handle 4 is mechanically welded with the movable door 2. There are two heat dissipation frame rows 5, and the heat dissipation frame rows 5 are installed on both sides of the box body 3 in a symmetrical structure. The cooling frame row 5 runs through the box body 3 .

[0025] The controllable ceiling 1 is composed of a ceiling structure 101, a driving mechanism 102, a rectangular cavity 103, and a rainproof mechanism 104. The described ceiling structure 101 is mechanically connected with the driving mechanism...

Abstract

The invention discloses a power box rainproof device for changing a ceiling height by pulling to open/close a heat dissipation port. The power box rainproof device comprises a controllable ceiling, amovable door, a box body, a movable door handle and a heat dissipation frame row, wherein the controllable ceiling is arranged in the true north direction of the box body and is connected to the box body; and the movable door is connected with the box body. The power box rainproof device has beneficial effects that the heat inside the box body is dissipated by using a triangular space formed between an edge plate and an edge plate fixing groove; the fixed shaft of the ceiling moves downward with a slide block by pulling a connecting rope such that an angle between the two edge plates becomes larger; when the two edge plates match the edge plate fixing groove, the triangular space is closed so as to achieve a purpose of avoiding the entry of rainwater; when the angle between the two edge plates becomes larger, the ends of the two edge plates away from the fixed shaft of the ceiling push a first plate and a second plate out of a rectangular cavity so as to achieve a rain shielding function and reduces the amount of the rain hitting the box body, thereby achieving a rainproof effect.

Description

technical field [0001] The invention relates to the field of power boxes, in particular to a rainproof device for a power box that can be pulled to change the height of the ceiling to control the switch of the cooling vent. Background technique [0002] Power boxes are widely used in loading instruments, meters, electronics, communications, automation, sensors, smart cards, industrial control, precision machinery and other items. Most of the materials are high-quality aluminum alloy profiles. Good performance and other characteristics, it is an ideal box for high-end instruments and meters. The current power box has the following defects: [0003] The aluminum alloy material is a metal object. Under the sun, the internal temperature will rise due to the high external temperature. Therefore, it is necessary to set up a cooling vent on the power box. When encountering rainy weather, rainwater can easily enter the box through the cooling vent, and The aluminum alloy material w...
