The invention discloses a rubber V-belt round mould vulcanizing device. According to the rubber V-belt round mould vulcanizing device, under the premise that the vulcanizing effect of a rubber V belt is not influenced, steam led into a vulcanizing tank can be effectively reduced, and the steam exhausting amount is reduced after the rubber V belt is vulcanized, so that the steam is saved, and energy waste is reduced. The rubber V-belt round mould vulcanizing device comprises the vulcanizing tank, a V-belt vulcanizing mould sleeve, a mould sealing cover plate and a steam-saving energy-saving part, wherein the bottom of a cavity of the vulcanizing tank is provided with a supporting flat plate; the lower end surface of the V-belt vulcanizing mould sleeve is supported by the upper surface of the supporting flat plate, and a plurality of annular V-belt molding grooves are formed in the outer side surface of the V-belt vulcanizing mould sleeve from bottom to top in sequence; the mould sealing cover plate is supported by the upper end surface of the V-belt vulcanizing mould sleeve; and the steam-saving energy-saving part is arranged in the V-belt vulcanizing mould sleeve, and an annular circulating cavity used for allowing the steam to be circulated is arranged between the outer side surface of the steam-saving energy-saving part and the inner side surface of the V-belt vulcanizing mould sleeve.

The invention relates to a preparation method of a waterproof compacting agent for concrete, and belongs to the technical field of preparation of additives of building materials. According to the preparation method, carboxyl-containing glycine serves as a raw material; the glycine is subjected to epoxy modification under alkaline conditions, and the number of active groups of the modified glycine can be increased; the modified glycine, serving as a complexing agent, reacts with calcium carbonate to generate a soluble calcium complex; the calcium complex can diffuse into the concrete spontaneously along with water, and reacts with silicate in the cement to generate insoluble crystals, and the effects that the strength and waterproofness of the concrete are enhanced while concrete gaps are filled are achieved; and the complexing agent is capable of circularly reacting, lithium silicate can react with free calcium in the cement to generate pectolite gelatin to fill the concrete gaps, and the strength and waterproofness of the concrete are improved. The waterproof concrete compacting agent prepared through the preparation method is good in waterproofness, the strength of the concrete is not prone to being reduced, fracturing is not prone to occurring in the use process, and the preparation method has wide application prospects.

The invention discloses an electricity-net composite fish blocking system and an electricity-net composite fish blocking method, wherein a rectangle ship passing net opening is formed in a ship passing passage which is arranged on a blocking net, and the size of the ship passing net opening fits in with the size of an electric fish-blocking and ship-passing facility, and a penetrating string is assembled in ship passing passage which is arranged on a blocking net; steel bars are arranged on the outer edge of a rectangle-shaped or U-shaped ship passing steel door frame of the electric fish-blocking and ship-passing facility and are used for connecting with a net-blocking and ship-passing net opening; the electric fish-blocking and ship-passing facility is arranged on the net-blocking and ship-passing net opening, two ends of the blocking net are fixed with ground anchors, a horizontal position of the electric fish-blocking and ship-passing facility and a vertical position of the electric fish-blocking and ship-passing facility are respectively fixed from four directions. The invention aims at providing the electricity-net composite fish blocking system and the electricity-net composite fish blocking method and the electricity-net composite fish blocking system and the electricity-net composite fish blocking method can not only effectively block fish, but also guarantee that large-tonnage ships can freely navigate without barriers for net blocking for fishing in large-scale landlocked waters.

The invention discloses an intelligent three-category peel box, comprising a mounting frame, a box body is embedded and welded in the middle of the mounting frame, a fire extinguishing component is installed under the sliding rail through an electric sliding block, and a drawing slot is installed inside the drawing slot. The insect trapping component has a scientific and reasonable structure, is safe and convenient to use, and is provided with a fire extinguishing component. When the fire is extinguished, the water liquid is not only sprayed out through the fire sprinkler, but the combustion inhibitor stored in the storage chamber is discharged through the discharge port and the material feed port. Cooperate with water and liquid to effectively extinguish the fire source, and solve the problem that the existing intelligent three-category peel box only relies on water to extinguish fire, and the water tank content in the installation frame is limited, which is easy to cause the fire source to be difficult to extinguish. Mosquitoes are lured by the trap light, so that the mosquitoes are caught by the sticky nets when they are close to the drawing board, which reduces the breeding of mosquitoes in the trash can, and further avoids the spread of infectious diseases caused by the breeding of mosquitoes.
