This utility model provides a novel universal power adapter, relating to the field of power adapter technology. It includes a housing assembly comprising an outer shell, an interface end cover, and a socket bottom cover. The socket bottom cover also includes an adapter circuit board mechanism disposed between the outer shell and the inner shell. A heat dissipation assembly comprises a heat dissipation sleeve embedded within the outer shell. A threaded heat-conducting plate is embedded in the heat dissipation sleeve. The threaded heat-conducting plate has a threaded structure, and the heat dissipation sleeve has annularly distributed heat dissipation holes. Heat generated during device operation is transferred to the outer shell and then conducted to the heat dissipation sleeve embedded therein. The threaded structure of the threaded heat-conducting plate increases the contact area with heat, efficiently absorbing heat and rapidly conducting it along the threaded path. The annularly distributed heat dissipation holes on the heat dissipation sleeve allow air to circulate inside and outside the sleeve. Hot air is discharged from the heat dissipation holes, and cool air is introduced, achieving continuous heat dissipation and maintaining a stable internal temperature of the device.

The container type energy storage battery pack comprises a container body, integral frames are fixedly connected to the upper portion and the lower portion of the front side and the rear side of the inner wall of the container body, a plurality of insulating plates are fixedly connected to the interiors of the integral frames, every two insulating plates are used in a matched mode, and the insulating plates are evenly distributed; battery cells are arranged on the inner sides of the insulating plates which are matched in pairs, a plurality of anti-falling structures which are in one-to-one correspondence with the battery cells are arranged on the front surface of the integral frame, and the back surfaces of the anti-falling structures are attached to the front surfaces of the battery cells. According to the invention, the transverse air duct, the air pipe, the heat dissipation groove, the heat dissipation fan, the air inlet duct, the air inlet fan and the dustproof net jointly form an efficient heat dissipation system; the transverse air duct and the air pipe introduce airflow into the integral frame to dissipate heat of the battery cells, the heat dissipation fan exhausts hot air, and the air inlet fan sucks fresh air from the air inlet, so that uniform heat dissipation of each battery cell is realized, and the stability and safety of the whole energy storage battery pack are improved.

The utility model discloses a U-shaped blowdown anti-reflux device of a gas-liquid separator, which belongs to the technical field of gas-liquid separation and comprises a separator main body, the bottom of the separator main body is communicated and connected with a blowdown block, and one end, far away from the blowdown block, of a blowdown pipe is connected with an electric ball valve. A control unit used in cooperation with the flow sensor and the electric telescopic rod is arranged on the side, located on the electric telescopic rod, of the fixing frame. The electric telescopic rod firstly drives the blocking block to block the sewage discharging block, so that the sewage flow is gradually reduced, the water hammer effect caused by sudden reduction of the water flow speed when a valve is directly closed traditionally is avoided, the problems of pipeline vibration, connecting piece looseness, pipeline breakage and the like caused by the water hammer effect are reduced, and safe and stable operation of equipment is guaranteed; the service life of the equipment is prolonged, the flow sensor monitors the flow in real time, the control unit is matched to accurately control the electric telescopic rod and the electric ball valve, meanwhile, the problems of low pollution discharge efficiency, equipment corrosion and the like caused by leakage are prevented, and it is guaranteed that the pollution discharge process is efficient and environmentally friendly.
