The utility model discloses an exhaust system of an aluminum casting die, which comprises a gas guide tank, the bottom end of the gas guide tank is fixedly connected with supporting legs, the top end of the left side of the gas guide tank is fixedly connected with a gas inlet, the right side of the gas guide tank is fixedly connected with a gas outlet, and a reset structure for an automatic closing device is arranged in the gas guide tank. According to the exhaust system of the cast aluminum mold, the movable plug is arranged, after the exhaust system is connected with an exhaust channel of the cast aluminum mold, air in the mold is guided into the top end of the interior of the air guide tank through the air inlet, the movable plug can be pushed to descend after the air pressure of the top end of the interior of the air guide tank reaches a certain value, and after the movable plug descends, the air outlet communicates with the interior of the air guide tank; and after the air pressure is reduced, the spring quickly jacks the movable plug back to enable the movable plug to be attached to the bottom of the positioning ring, so that the device is automatically closed while the aluminum liquid is prevented from overflowing, and the problem of automatic opening and closing is solved.

The utility model relates to the technical field of communication facilities, in particular to a communication iron tower with a reinforced structure, which comprises a fixing table, a supporting assembly is arranged at the top of the fixing table, the supporting assembly comprises supporting stand columns, the supporting stand columns are fixedly arranged at the top of the fixing table, and the supporting stand columns are distributed at the top of the fixing table in a front-back parallel mode. Supporting rods are fixedly connected to the opposite sides of the supporting stand columns, the supporting rods are connected in an up-down diagonal mode, anti-climbing frames are fixedly connected to the outer sides of the supporting stand columns, breast boards are fixedly connected to the bottoms of the anti-climbing frames, a containing table is fixedly connected to the tops of the supporting stand columns, and a supporting frame is fixedly connected to the interior of the containing table. According to the communication iron tower of the reinforced structure, through diagonal connection of the supporting rods, not only can the situation that people without miscellaneous things climb the supporting stand columns be prevented to a certain extent, so that potential safety hazards are reduced, electric shock accidents are avoided, and the stability and safety of the supporting stand column structure can be effectively improved.

The invention discloses an automatic water-adding device for explosion-proof water shed for mines and an automatic water-adding method thereof, comprising a hanger, a hook and a water bag. The hanger is connected with a fixed frame, and the fixed frame is provided with a vertical slide rail; the hanger is slidably connected with a first slide bar; the bottom end of the first slide bar is connected with a load-bearing rod; the load-bearing rod penetrates the slide rail and is slidably connected with the fixed frame; two fixed shafts are respectively connected on both sides of the load-bearing rod, and the two fixed shafts are respectively on the inside and outside sides of the water bag; a floating block is provided at the bottom end of the first fixed shaft; and a first top block is provided at the bottom end of the second fixed shaft. The lower part of the fixed frame is slidably connected with a second slide bar, and the second slide bar is provided with a second top block, a reset spring and a tooth plate; the fixed frame is connected with a vertical rotating shaft through a mounting block, and a gear, a limit ring and a torsion spring are sequentially sleeved on the rotating shaft from top to bottom, and the bottom end of the rotating shaft is connected with a valve plate of the main water pipe of the water bag; the tooth plate is meshed with the gear. The up and down movement of the floating block drives the first top block to contact and separate with the second top block, thereby realizing automatic water addition and stop of the water bag, which is convenient, safe and energy-saving.

The utility model discloses a safe outdoor transformer station, which relates to the technical field of transformer stations, and comprises a transformer station main body, the bottom of the transformer station main body is fixedly connected with supporting legs, the circumferential surfaces of the supporting legs are fixedly connected with supporting plates, and a transformer is arranged in the transformer station main body; a moisture-proof device is arranged in the transformer substation main body, the moisture-proof device comprises a telescopic rod, force for driving an extrusion rod to move downwards through downward displacement of a collection box is matched with a storage box, a switch rod, a pressing rod and other assemblies in the moisture-proof device, and the effect of driving a rotating rod to rotate through rotation of an overturning cover plate is achieved; the effect that the overturning cover plate is automatically closed when it rains and is opened when it does not rains is achieved, meanwhile, the effect of spraying a dehumidizer into the transformer substation body for dehumidification is achieved, corrosion and damage to equipment caused by the humid environment are prevented, and the service life of the equipment is prolonged.
