The application discloses a wood gallery bridge fire extinguishing device and relates to the technical field of fire safety equipment. The wood gallery bridge fire extinguishing device comprises a buried track and grounding reinforcing ribs installed on the outer surfaces of the two sides of the buried track. A driving mechanism is installed on the inner wall of the buried track. A fire extinguishing mechanism is installed on the top surface of the driving mechanism. The driving mechanism is used for adjusting the position of the fire extinguishing mechanism. A water supply mechanism is installed on the outer surface of the buried track. The water in a river channel is sucked to an extension pipeline by a diving pump under the control of a control system. A servo motor drives a ball screw to rotate, so that a moving slide table moves at the inner wall of the buried track. The moving slide table moves to the central position of the buried track. The extension pipeline transports the water flow in the river channel to a water delivery pipeline. The water is sprayed out through high-pressure nozzles. The distributed high-pressure nozzles can expand the spraying area, so that the wood gallery bridge wood structure is sprayed and extinguished, and the fire spreading is prevented.

The utility model relates to a loudspeaker technical field especially, more particularly to a loudspeaker with LED lamp, including shell, the top of shell is provided with top board, and the top board is opened with through -hole no.
