Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Examples

Referring to fig. 1 to 4, the present embodiment provides a moisture-proof power cabinet, which mainly includes: a cabinet 11 and a moisture-proof mechanism.

An openable and closable cabinet door (not shown) is installed at one side of the cabinet body 11, and the bottom of the cabinet body 11 is provided with support legs 111. The cabinet door can be opened and closed so as to facilitate the installation and maintenance of electronic components in the cabinet body 11. The cabinet body 11 can be raised to landing leg 111, makes cabinet body 11 keep away from ground, avoids moist ground to influence dampproofing electric power cabinet's use.

The moisture-proof mechanism comprises a first air inlet pipe 131, a second air inlet pipe 132 and an air outlet pipe 133, the first air inlet pipe 131, the second air inlet pipe 132, the cabinet body 11 and the air outlet pipe 133 are sequentially communicated, and an exhaust fan 134 is installed in the air outlet pipe 133. The first air inlet pipe 131 is located on the outer side of the cabinet body 11 and arranged along the height direction of the cabinet body 11, the upper end of the first air inlet pipe 131 is open, the lower end of the first air inlet pipe 131 is closed, and the top of the first air inlet pipe 131 is located above the cabinet body 11. The second air inlet pipe 132 is positioned between the first air inlet pipe 131 and the cabinet 11, and the air outlet pipe 133 extends to the outside of the cabinet 11.

After the gas above the cabinet 11 sequentially passes through the first air inlet pipe 131, the second air inlet pipe 132 and the cabinet 11, the gas is discharged from the air outlet pipe 133, so that moisture accumulation can be avoided in the cabinet 11, and heat generated by electronic components in the cabinet 11 can be taken away. Because the gas that the water content is more is close to ground, consequently, set up the top of first intake pipe 131 in the top of the cabinet body 11, can avoid inhaling the gas that the water content is more near ground department in the cabinet body 11.

As shown in fig. 1, the second air inlet duct 132 is disposed obliquely so as to prevent foreign materials from entering the tub 11 through the second air inlet duct 132.

The connection cap 137 is provided with a plurality of air inlets 138. The protective cover 136 is convenient to disassemble, assemble and replace through the arrangement of the connecting cap 137.

The inner side of the connecting cap 137 is provided with a limiting groove 139, a filter screen 141 is movably connected in the limiting groove 139, the diameter of the filter screen 141 is larger than the inner diameter of the first air inlet pipe 131, and the filter screen 141 is made of stainless steel. Through the setting of filter screen 141, can avoid in the debris gets into first intake pipe 131 better. When the filter screen 141 is installed, the filter screen 141 can be placed into the limiting groove 139 of the connecting cap 137, and then the connecting cap 137 is screwed on the first air inlet pipe 131.

The lower side of the filter screen 141 is connected with a moisture absorption box 143 through a connecting rod 142, the moisture absorption box 143 is provided with a plurality of vent holes, and the moisture absorption box 143 is filled with a moisture absorbent. Through the setting of moisture absorption case 143 and absorbent, can further improve dampproofing performance of dampproofing electric power cabinet.

The top welding of moisture absorption case 143 has engaging lug 144, and engaging lug 144 is connected with connecting rod 142 through bolt 145 to make things convenient for moisture absorption case 143 dismouting, change. When the moisture absorption box 143 is installed, the connecting lug 144 may be connected to the connecting rod 142 via the bolt 145 to connect the moisture absorption box 143 to the filter screen 141, and then the moisture absorption box 143 is placed into the first air inlet pipe 131 from top to bottom, and then the connecting cap 137 is screwed onto the first air inlet pipe 131.

Finally, it should be noted that: the present invention is not limited to the above-described preferred embodiments, but various modifications and changes can be made by those skilled in the art, and the embodiments and features of the embodiments of the present invention can be combined with each other arbitrarily without conflict. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
