The utility model discloses a cooling device for an end winding of a generator, which relates to the technical field of electrics and comprises a generator body, an inner cover support plate is fixedly mounted on the surface of the generator body, an end cover body is slidably mounted on the surface of the inner cover support plate, and a butt joint support groove is formed in the surface of the inner cover support plate. According to the cooling device for the end winding of the generator, the first guide plate pushes the second guide rod to slide from the inner side of the butt joint support plate to the inner wall of the positioning support groove, so that butt joint installation of the end cover body and the inner cover support plate is achieved; by means of the mode, the convenience of butt joint combination between the end cover body and the inner cover supporting plate is guaranteed, meanwhile, the convenience of disassembly maintenance and cleaning operation when the generator body works for a certain period of time is guaranteed, and the defects that a traditional generator body and an end cover body are located through bolts, rusting is easily caused, and separation operation is not convenient are overcome.

The invention relates to the technical field of ship stern tube construction, in particular to a stern tube epoxy baffle fixing device which comprises stern tube bodies and a connecting steel casting, the stern tube bodies are fixed to the two ends of the outer side of the connecting steel casting, and threads are fixed to the ends, close to each other, of the outer sides of the two stern tube bodies. Epoxy baffle assemblies are assembled at the ends, close to each other, of the two stern tube bodies and located on the outer sides of the connecting steel castings, pressure applying mechanisms used for driving the semi-arc baffles to be sealed with the stern tube bodies are arranged on the outer sides of the stern tube bodies, the pressure applying mechanisms comprise threaded rotating rings and traction claws, and the traction claws are assembled on the outer sides of the threaded rotating rings. One end, far away from the threaded rotating ring, of the traction claw is abutted against and contacted with the semi-arc-shaped baffle; the part between the stern tube body and the continuous steel casting is effectively sealed through the epoxy baffle assembly, so that water is prevented from permeating into the part between the stern tube body and the continuous steel casting, and a water source is prevented from entering the stern tube.

The utility model relates to the technical field of power transmission, and discloses an aluminum alloy bus duct shell, which comprises a first side plate, a second side plate, a first cover plate and a second cover plate, the first side plate and the second side plate are C-shaped plates, the first side plate and the second side plate are oppositely arranged, a gap is arranged between the first side plate and the second side plate, a first heat dissipation part is arranged outside the first side plate, and a second heat dissipation part is arranged outside the second side plate. A first heat dissipation part is arranged on the outer side of the first side plate, a second heat dissipation part is arranged on the outer side of the second side plate, the first cover plate is connected with one end of the first side plate and one end of the second side plate, the first cover plate is an I-shaped plate and comprises a first vertical plate, a first horizontal plate and a second vertical plate which are sequentially connected, and a first supporting plate is arranged on the outer side surface of the first horizontal plate; the second cover plate is connected with the other end of the first side plate and the other end of the second side plate, the second cover plate is an I-shaped plate, the second cover plate comprises a third vertical plate, a second horizontal plate and a fourth vertical plate which are connected in sequence, and a second supporting plate is arranged on the outer side surface of the second horizontal plate. The LED lamp is high in supporting capacity, not prone to deformation, even in heat dissipation and light in weight.

The application discloses a safe automatic opening and closing umbrella which is simple in structure, capable of collecting water drops and preventing floor from being wetted. The umbrella comprises an umbrella body, a handle provided on the umbrella body and a handle sleeve. The handle sleeve is provided with a water draining channel for the umbrella body to pass through. A water collecting groove is formed in the bottom of the handle sleeve and is communicated with the water draining channel. A closing device is arranged at the port of the water collecting groove of the handle sleeve and is used for closing the water collecting groove after the water collecting groove collects water.
