The invention relates to the technical field of doors and windows, in particular to a 95 outward-opening window screen integrated narrow-edge door and window. Comprising a frame, a mullion, an opening sash, a fixed sash and a window screen installed on the indoor side of the opening sash. The frame comprises an upper frame and a right frame, the mullion comprises a transverse mullion and a vertical mullion, the parts, correspondingly opened and closed with the opening sash, in the upper frame and the right frame are an upper window sash frame and a right window sash frame respectively, and the parts, correspondingly opened and closed with the opening sash, in the transverse mullion and the vertical mullion are a vertical window sash mullion and a transverse window sash mullion respectively; the opening sash is installed on the upper sash frame and the transverse sash mullion through a pair of hinges and locked on the vertical sash mullion through a first locking piece, and the opening sash is an outward opening sash. Compared with an outward-opening window in the prior art, the outward-opening window has the advantages that the structure of a conversion frame is omitted, the outward-opening opening sash is directly installed on the mullion and the frame, the proportion of glass is increased, and light is more transparent and brighter.

This invention relates to a firefighter's protective suit that combines anti-icing and warmth retention properties. It consists of a jacket and trousers. The jacket collar material, from the outside in, comprises an outer layer I, a waterproof and breathable layer I, a heat insulation layer I, an outer woven fabric layer I, and a warmth-retaining fabric layer I. The jacket hem material, from the outside in, comprises an outer layer II, a waterproof and breathable layer II, a heat insulation layer II, a comfort layer woven fabric III, and a warmth-retaining fabric layer II. The other parts of the jacket material, from the outside in, comprise an outer layer III, a waterproof and breathable layer III, a heat insulation layer III, and a comfort layer woven fabric V. The jacket cuffs are thickened ribbed cuffs. The trousers material, from the outside in, comprises an outer layer IV, a waterproof and breathable layer IV, a heat insulation layer IV, and a comfort layer woven fabric VII. This invention focuses on the warmth retention of the comfort layer and the anti-icing design of the outer layer of the firefighter's protective suit, achieving both warmth retention and anti-icing properties, ensuring the comfort of firefighters during movement and maintaining operational efficiency.

The utility model discloses a plate-shaped heat preservation roof which comprises two symmetrical purlines fixedly connected to a building roof through bolts, the tops of the two purlines are fixedly connected with a bottom plate, the top of the bottom plate is provided with a rock wool plate, the top of the rock wool plate is provided with two symmetrical inner supports, and the inner supports are fixedly connected with the bottom plate through bolts. A waterproof vapor-permeable film is installed on the tops of the two inner supports, a roof panel is installed on the top of the waterproof vapor-permeable film, L-shaped plates are fixedly connected to the left sides and the right sides of the tops of the two purlines through bolts, and the tops of the L-shaped plates are fixedly connected with the bottoms of the inner supports through bolts. According to the roof structure, the bottom plate, the rock wool plate and the waterproof vapor permeable film are installed, so that the bracket plays a role in installing an auxiliary structure during installation, the bracket can disperse the load borne by the roof structure, then the connecting plate supports the bottom of the bottom plate, and finally the connecting plate supports the bottom of the bottom plate to form a stable supporting structure.

The utility model relates to the technical field of mariculture, in particular to a light supplementing and heat preserving device of a mariculture pond, which comprises two mounting columns and a culture pond body, the lower ends of the two mounting columns are provided with mounting grooves, the interiors of the two mounting grooves are jointly provided with a shielding device, and the two mounting columns are arranged in the culture pond body. The outer surfaces of the two mounting columns are jointly provided with a heat preservation assembly, the front portion and the rear portion of the upper end of the culture pond body are each provided with three heaters, the left portions and the right portions of the lower ends of the two mounting columns are each provided with a supporting column, and the lower ends of the four supporting columns are each provided with a fixing plate; universal wheels are arranged at the lower ends of the four fixing plates, and telescopic air cylinders are fixedly installed at the upper ends of the four fixing plates in a penetrating and inserting mode. According to the light-supplementing and heat-preserving device of the seawater culture pond, the light-supplementing and heat-preserving device can be conveniently and quickly mounted and dismounted, the temperature of water in the culture pond body can be conveniently preserved, and the heat-preserving effect is better.

The invention discloses a mercury mining area soil pollution abatement agent and a preparation method and application thereof, and particularly relates to the technical field of soil remediation agents. The treatment agent comprises an organic matrix containing arbuscular fungi, humic acid and mercury-tolerant plants, wherein the ratio of the organic matrix containing the arbuscular fungi to the humic acid is (1-3): 1. The arbuscular fungi and the humic acid are jointly applied to the mercury-contaminated soil, the infection rate of the arbuscular fungi can be greatly increased, and the biomass, the mercury tolerance concentration and the mercury extraction amount of mercury remediation plants are increased. The mercury pollution treatment effect and the phytoremediation effect are better than those of single application of humic acid or arbuscular fungi.

The utility model discloses a windproof mountain photovoltaic power station which comprises a base, a rotating motor is installed at the top end of the base, a second windproof plate is arranged on the outer side of the base, and a disassembly and assembly structure is installed at one end of an installation block. The wind power sensors are installed on the two sides of the second windproof plate, the wind power sensors can sense the strength of wind, when the strength of the wind is too high, the first servo motor works to drive the threaded rod to rotate, and the threaded rod rotates to drive the first windproof plate to ascend; the first windproof plate can perform windproof protection on the photovoltaic power station, the first windproof plate can descend when not needed, solar energy absorption of the solar cell panel is not affected, meanwhile, when wind is too strong, the wind blows the fan blades to rotate, and the fan blades rotate to generate certain electric power to supply power to the device through cooperation of wind power and the generator. And the device can realize certain energy conservation, so that the purpose that the mountain photovoltaic power station is convenient for wind prevention is achieved.
