The invention relates to the technical field of noise detection, and discloses unmanned aerial vehicle mounted environmental noise detection equipment, which comprises an unmanned aerial vehicle main body, a plurality of propellers are arranged on the unmanned aerial vehicle main body, and an air guide arc-shaped cover matched with the propellers for use is arranged at the bottom of the unmanned aerial vehicle main body. A noise detector and a detection microphone are arranged in the air guide arc-shaped cover; a flow guide and noise reduction mechanism used for reducing noise of the detection microphone is arranged in the air guide arc-shaped cover, and the flow guide and noise reduction mechanism comprises a flow guide and noise reduction frame fixedly installed in the air guide arc-shaped cover. By arranging the air guide arc-shaped cover, the flow guide noise reduction frame, the noise detector, the detection microphone, the mounting bracket and the flow guide angle adjusting mechanism, airflow is diffused to the surrounding under the arc-shaped action of the air guide arc-shaped cover, so that the airflow is far away from the detection microphone area, and the noise of the airflow is prevented from interfering the noise detector and affecting the accuracy of a detection result.

This application provides a novel ship control hull mold casting system, relating to the field of metal casting molds. It includes a gating structure on one side of the cavity and an venting structure on the remaining sides of the cavity. The gating structure is stepped, positioned at the top of the cavity and higher than the cavity itself. The gating structure includes a riser, a main channel, two branch channels, and multiple sub-channels connected sequentially along the pouring direction. The two branch channels extend obliquely to both sides from the ends of the main channel, with their widths gradually decreasing. Each branch channel branches out two spaced sub-channels on its side facing the cavity. The height of the sub-channels gradually decreases, and their width gradually increases at their ends. The height of the sub-channels is lower than the height of the branch channels, and the height of the branch channels is lower than the height of the main channel. The venting structure includes multiple venting slag bags spaced apart and connected to the bottom of the outer side of the cavity. This application effectively solves the technical problems of turbulence and slag inclusions easily generated by traditional flow channels.

The invention discloses electronic equipment, and belongs to the technical field of electronic products. The electronic equipment comprises a frame body, the frame body is provided with a function channel, the function channel comprises a first buffer area section, the first buffer area section comprises a first shunting section and a second shunting section, the first end of the first shunting section and the first end of the second shunting section are communicated and both communicated with the outside, and the second end of the first shunting section is communicated with an inner cavity of the frame body. And the second end of the second shunting section is communicated with the part between the first end and the second end of the first shunting section. And under the condition that the frame body is impacted by external fluid, at least part of the fluid in the second flow dividing section flows back into the first flow dividing section through the second end of the second flow dividing section, so that the fluid in the first flow dividing section is prevented from flowing towards the second end of the first flow dividing section.
