To meet the experimental requirements, many power devices are usually configured in the mechanical and electrical room of the laboratory. These power devices generate heat during operation. The continuous operation and heat dissipation of multiple power devices can easily cause the temperature inside the mechanical and electrical room to be too high. Since the mechanical and electrical room is usually a relatively enclosed room, the heat cannot be dissipated from the mechanical and electrical room in time, resulting in the power devices being in a high-temperature environment for a long time, which may cause malfunctions or even damage, affecting the normal operation and service life of the power devices, and also affecting the normal use of the laboratory.

[0003] Due to the poor air fluidity in the mechanical and electrical room, most of the heat is evenly distributed in the upper part of the mechanical and electrical room.

The repeated swing of the connecting shaft 29 causes the fixed sleeve 28 to drive the air intake hood 18 to swing repeatedly, thereby changing the angle at which the device extracts hot air, facilitating the extraction of hot air in the electrical equipment room from multiple directions, and discharging it after being filtered by the filter box 13 and cooled by the condenser 11, improving the heat dissipation effect of the device.

[0054] Axially pull the rotating shaft 123 to separate the limit groove 118 from the limit tooth 120. At this time, the return spring 122 is compressed. The rotating shaft 123 can be rotated. The rotation of the rotating shaft 123 drives the rotation of the gear 121. The meshing transmission between the gear 121 and the tooth groove 103 causes the extension column 104 to move up and down relative to the support column 15. A slide rail and slider can be used between the extension column 104 and the support column 15 to achieve limit, so as to ensure that the extension column 104 makes a linear lifting motion. The movement of the extension column 104 drives the mounting bracket 19 to move up and down synchronously. The movement of the mounting bracket 19 drives the air intake hood 18 to move up and down synchronously, thereby adjusting the air intake hood 18 to a suitable height. Release the rotating shaft 123. Under the action of the return spring 122, the rotating shaft 123 is reset, and the limit tooth 120 is reinserted into the limit groove 118. The limit sleeve limits the rotating shaft 123, thereby keeping the air intake hood 18 at the corresponding height. Since hot air mostly accumulates at the top of the electrical equipment room, it is convenient to adjust the position of the air intake hood 18 according to the height of the equipment room, improving the practicability of the device.

[0055] It is convenient to pull out the partition plate 110 through the handle 108, so that the collection box 109 is located below the filter net 111. Move the fixed plate 112 up and down repeatedly along the vertical direction through the handle 108. When the fixed plate 112 moves repeatedly, the filter net 111 contacts the brush rods 114 on both sides of the through groove 105, so as to remove the dust attached to the filter net 111 through the brush rods 114, and the dust falls into the collection box 109, facilitating the cleaning of the filter net 111. After the cleaning is completed, insert the partition plate 110 into the first placement groove 106 to separate the collection box 109 from the filter net 111, and then the heat dissipation work can continue. The cleaning is convenient and labor-saving.

[0056] The above are only the preferred embodiments of the present invention, and are not used to limit the protection scope of the invention. Therefore, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
