Snow removal or snow clearing is the job of removing snow after a snowfall to make travel easier and safer. This is done by both individual households and by governments and institutions.

Environment-friendly road surface ice and snow melt coating material, preparation method thereof and using method thereof

ActiveCN102199398AEnsure Snowmelt RequirementsPrevent loose grainsIn situ pavingsOther chemical processesSnow removalSnowpack
The invention relates to an environment-friendly road surface ice and snow melt coating material, a preparation method thereof and a using method thereof. Serious consequences such as traffic jam and the like can be caused by snow accumulation in winter; and at present, a snow removal method comprises passive snow removal and active snow removal, wherein in the passive snow removal, the operating efficiency of manual snow removal is low, mechanical snow removal is incomplete relatively in clearing, and for the spreading of a snow melt agent, substances with the snow melt effect are mixed simply only, so the spreading is non-uniform, and the snow melt agent dispersed to peripheral air has the major influence on environment; and the active snow removal is high in cost, and has a certain damage to structures of road surfaces, so the service life of roads is shortened. In the environment-friendly road surface ice and snow melt coating material, after being loaded on a carrier material, the snow melt substances are mixed with emulsified asphalt, water-soluble epoxy resin and a curing agent and sprayed on the road surfaces to form an ice and snow melt coating, so that the roads have the function of melting snow actively. By the environment-friendly road surface ice and snow melt coating material, an ice point of water is reduced to between -5 and -20 DEG C so as to clear the ice and snow of the roads, and the coating material has the sustained-release function, is high in coating adhesivity and wear-resisting effect, low in cost and convenient to maintain, and can prolong the life of the road surfaces effectively.

Homeowner's method of snow removal with a motor vehicle

This method provides various high-power-ratio snow removal devices which clear paths narrower than the motor vehicles. We use small, light, low-priced, yet also safe, durable devices to clear the narrow swaths. High power ratios result from applying motor vehicle horsepower to small snow removal devices similar to those found on lawn tractors. Such devices may comprise moldboard plows (FIGS. 3, 9, 10, 11, 15, 16), snow throwers (FIGS. 7 and 13), or combinations of both types (FIG. 12 and 17). Quick-connect and quick-release fittings (FIGS. 3A, 3B, 6, 8, 9A, 9B, 14) position each device for temporary propulsion by a vehicle. The connectors allow quick conversion of the family car to a plowing machine, and when plowing is done, quick re-conversion. A moldboard plow of about half the car's width (FIG. 3) is our preferred embodiment. The mini-moldboard (FIG. 10) is least expensive. Deepest snow can be handled by our tall, narrow moldboard (FIG. 15). We protect homeowners, their cars and their plows from injury when plows strike hidden objects. Protection devices comprise safety springs (60) and pivots (63, 67 and 69) of FIG. 3B, the tension-release mechanism mentioned but not detailed in FIG. 15, annor shields (396, 398) of FIG. 16 and various others mentioned or provided for in our drawings but not detailed. We prefer cars' chassis tie-down ears (72) in FIG. 3A, as connector points for our plow or thrower arms. For cars lacking such ears, we propose add-on ears. For example, tie-down ear (126) in FIG. 6.

Vehicle-mounted multifunctional snow remover

ActiveCN102094401AImprove snow removal qualityFast snow removalSnow cleaningHydraulic motorSnow removal
The invention belongs to the technical field of snow removal equipment for removing snow on a road and spreading a snow-melting agent, and in particular to a vehicle-mounted multifunctional snow remover. The vehicle-mounted multifunctional snow remover comprises a vehicle cab, a snow removal shovel device, a vehicle chassis, a hydraulic pump station, a snow-melting agent spreader and a swing ventral shovel device, wherein, the swing ventral shovel device is arranged in the middle part of the vehicle chassis; an ice-breaking roller device is arranged in the front of the swing ventral shovel device, and a snow-sweeping roller brush device is arranged in the back of the swing ventral shovel device; the ice-breaking roller device consists of an ice-breaking roller chute, an ice-breaking roller slide rail, a spring seat, a spring bar, a spring, an ice-breaking roller and an ice-breaking roller lift cylinder; and the snow-sweeping roller brush device consists of a roller brush chute, a roller brush slide rail, a support plate, a support axle, a worm wheel, a roller brush frame, a roller brush assembly, a worm, a roller brush rotating-angle adjustment hydraulic motor and a roller brush lift cylinder. The vehicle-mounted multifunctional snow remover has the advantages of completing the four procedures of pushing snow, breaking ice, sweeping and spreading the snow-melting agent once, improving the snow removal effect, accelerating the snow removal speed and protecting the original asphalt pavement from damage.

Catalytic decomposition low-concentration hydrogen peroxide reactor, combustion chamber and application thereof

The invention relates to a catalytic decomposition low-concentration hydrogen peroxide reactor and a combustion chamber, which solve the problem that in the prior art, price is expensive, safety is not high, freezing point is high, decomposition temperature and ignition temperature are high, purpose is single and the like. A multilayer low-bed-load and pre-contact fine silver net catalysis bed for catalytic decomposition of 40%-70% of hydrogen peroxide is adopted, and service life is greatly prolonged. Radial holes or/and axial holes are arranged on a laryngeal casing of the catalytic decomposition low-concentration hydrogen peroxide reactor for using in underground reactor oil recovery by heating, mining and marine accident self rescuing and a life support system of spaceships and rocket oxidizer storage tank supercharging. The catalytic decomposition low-concentration hydrogen peroxide combustion chamber is provided with a plurality of radial spraying holes for spraying diesel oil or kerosene, an electronic spark plug for ignition, a combustion chamber body with the 40%-70% of hydrogen peroxide serving as a regeneration cooling agent and two kinds of spraying tubes, and the catalytic decomposition low-concentration hydrogen peroxide combustion chamber can be used for thrust chamber gas spraying thrust of a plurality of military projects and road ice and snow removal by heat and crude oil pollution.
