Description

C-shaped steel sliding cover circular arch greenhouse

Technical Field

The utility model relates to a greenhouse.

Background

The existing sunlight greenhouse adopts an adobe (or masonry) rear wall, a front slope-built small arch truss frame, a straw curtain or a cotton quilt for heat preservation, the adobe (or masonry) rear wall is time-consuming and labor-consuming in construction, high in construction cost, low in heat preservation efficiency, easy to collapse and damage people when meeting heavy rain or soaking water, and the high rear wall shields sunlight, so that the front greenhouse and the rear greenhouse have to keep a certain distance, and the land utilization rate is reduced; a front slope small arch truss is erected, and the front slope small arch truss is usually collapsed in case of a large snow disaster due to the fact that the front slope small arch truss is close to the parallel ground; but not as thick as can be rolled! The thin straw curtain or the roll quilt (the porous fiber material) with the thickness of 2 cm or 3 cm does not have much heat preservation and insulation effect at all, and is cold in winter and hot in summer. And the more the roll is rolled, the denser the roll is, the heat preservation performance is gradually reduced year by year, the roll needs to be replaced after 5-10 years of exposure to the sun and rain, and the service life is short. The whole greenhouse is more dangerous to collapse by absorbing water and pressing in rainy days, not only property is lost, but also human bodies are seriously threatened! Because the heat preservation efficiency of the roll quilt is low, the greenhouse in some cold regions needs to be provided with additional heating facilities to consume a large amount of energy to maintain the production in winter. Both theory and practice prove that 80% of heat of the greenhouse is dissipated from the greenhouse surface, so that the improvement of the heat preservation of the greenhouse surface is the important factor! And the common masonry structure human-occupied buildings not only use thick and heavy materials and are complicated to build, but also cannot effectively resist wind, snow and earthquake. The answer to the above problem is not difficult to find in the wisdom of human ancestors: that is the arch bridge of china. A thin stone arch can bear tens and hundreds of tons of load, which is dozens and hundreds of times of the load bearing of the same straight line material. The human ancestor is again a wisdom from where to obtain- -nature! Human ancestry observed: in nature, many animals wrap their most important organs, the brain and more important than their lives, the child, with only a non-thick but spherical shell or egg, and the next most important internal organs of the body, also protected by an arched rib or arched shell.

In winter sunshine, the rigid heat-preservation sunshade sliding cover 5 slides to the fixed heat-preservation sunshade cover 4 and is overlapped with the fixed heat-preservation sunshade cover 4 up and down, so that sunshine is emitted into the daylighting greenhouse surface 6 to heat the greenhouse, and after the sunshine is cooled down, the rigid heat-preservation sunshade sliding cover 5 slides to the daylighting greenhouse surface 6 and is butted with the fixed heat-preservation sunshade cover 4 to completely seal the heat-preservation greenhouse; in summer sunshine, the rigid heat-preservation sunshade sliding cover 5 slides to the position of the lighting greenhouse surface 6 to shield the sunshine so as to cool the greenhouse.

The utility model has the advantages that: the C-shaped steel arched beam and pulley groove not only has thin and economical materials and low manufacturing cost, but also improves the wind resistance and snow pressure resistance of the greenhouse, and the light waterproof rigid heat-insulation sun-shading sliding cover replaces a straw curtain or a quilt, thereby greatly improving the heat-insulation efficiency, prolonging the service life and resisting rain, snow and wind, and saving time and labor for folding and unfolding. Not only so, when the utility model discloses when jumping out the agricultural production field and being used for the building field of human living, production, it has remedied the regret of conventional building to sunshine underutilization, makes the building open chest in cold day and holds a feeling in the palm and collect this cheapest and greenest energy to the utmost extent- -solar energy! (note: there are walls on east, south, west, north, top five sides of the conventional building, only some areas of wall of south open the window for lighting, the sunshine injection amount is very limited in the cold day, but the greenhouse can all-round lighting, fully warm the room, and after the sunshine is retreated, close the slip cap and fully preserve the heat for the greenhouse), it has superstrong heat preservation, sun-shading, collect the sunshine, resist hurricane, resist snow pressure, resist the strong performance of the earthquake, and the material is recoverable, reuse, reduce the emission of the construction rubbish and lower fabrication cost than the conventional greenhouse and building, will relieve the energy crisis of the earth effectively while bringing energy-conservation, safety to people.

Detailed Description

In fig. 1, the cross section of the greenhouse main body is a circular arch without a rear wall, a plurality of hot galvanizing C-shaped steel arched beam and pulley grooves 1, a hot galvanizing C-shaped steel ground beam 2 and hot galvanizing C-shaped steel beam cross beams are connected into a net-shaped half barrel surface through bolts, cement columns or ground bolts with the diameter of 180mm which is more than that of a frozen soil layer are connected below the C-shaped steel ground beam at intervals of 2-3 meters to replace steel bar cement ground beams with complicated process and high manufacturing cost, and the steel bar cement ground beam is omitted here, a fixed heat preservation sunshade cover 4 (an extruded sheet with the thickness of 80-100mm and coated with heat preservation anti-crack mortar on both sides) is covered on the back sun surface of the circular arch greenhouse main body, and a rigid heat preservation sunshade sliding cover 5 (an extruded sheet with the thickness of 80-100mm and coated with aluminum foil glass fiber cloth) can integrally slide along the C-shaped steel arched. When sunshine is generated in winter, the motor drives the transmission shaft 11 to pull the pull ropes 12 connected with two ends of the rigid heat-preservation sunshade sliding cover 5 to slide the rigid heat-preservation sunshade sliding cover 5 to the fixed heat-preservation sunshade cover 4 to be vertically overlapped with the fixed heat-preservation sunshade cover 4, so that the sunshine is injected into the daylighting greenhouse surface 6 to heat the greenhouse, after the sunshine is cooled down, the rigid heat-preservation sunshade sliding cover 5 is slid to the daylighting greenhouse surface 6 to be butted with the fixed heat-preservation sunshade cover 4, and the heat-preservation block and the multilayer cloth curtain seal 8 fill a gap between the fixed heat-preservation sunshade cover 4 and the heat-preservation sunshade sliding cover 5, so that the greenhouse is comprehensively; in summer sunshine, if the greenhouse as agricultural production can open the lower ventilation window 9 and the upper ventilation window 10 for greenhouse cooling (here replace the roll film vent of conventional sunlight greenhouse with transparent plate ventilation window, overcome the roll film vent and drawn into the problem that dust and mud influence daylighting), and if the greenhouse as human-occupied building, can slide rigid heat preservation sunshade sliding closure 5 to daylighting greenhouse face 6 department (do not slide to the end, the bottom is about 1 meter away from ground, let direct light penetrate, and scattered light can get into from the lower part and provide indoor daylighting), shelter from sunshine for greenhouse cooling, can't get into the greenhouse when direct sunlight, can be like under the tree shade in the greenhouse, it is cool, years's practice proves: in the area north of the Yangtze river, as long as the heat preservation of the greenhouse is qualified, direct sunlight cannot enter the greenhouse, and the air conditioner can be basically omitted. In the winter with the sunshine rate in Beijing area, the greenhouse almost does not need extra heating equipment, can maintain the indoor temperature to be more than 15 ℃ by the solar energy and the super heat insulation performance of the fixed heat insulation sunshade cover and the heat insulation sunshade sliding cover, can be paved with hard or soft solar cell panels for the power utilization of electric appliances in the whole greenhouse, particularly dead areas such as disaster areas, forest fire prevention areas, high-speed railway guardrails, nomadic areas, field military operation, outdoor tourism and the like, does not need to be paved with power supply lines, and can completely realize self-sufficiency. The innovative process points of the scheme are as follows: an adjustable C-shaped steel cold-bending forming machine, a pipe bender, a plurality of small drilling machines and a plurality of coils of hot-galvanized iron sheets (no gaps and transportation space saving) can be used for producing C-shaped steel with any length and specification on site, dozens of tons of steel are produced in one day, the material connection cost (2-3 connections are needed for dozens of meters of an arched beam) and the transportation cost are saved, then a welding point is not needed in bolt connection, 3 and 4 common people can build a 600-square-meter greenhouse framework by a wrench, and the building speed is 2-3 times that of a conventional greenhouse. The hot galvanizing C-shaped steel arched girder and the pulley groove are used for replacing the traditional steel bar steel pipe welding truss arched girder, professional welders are not needed to eliminate fire hazard, painting and corrosion prevention are not needed to pollute the site (generally, paint is removed and rusted in 1 and 2 years, and rusted and broken in more than ten years), a lot of labor is saved, the appearance is attractive, and the service life is prolonged by at least one time.

Fig. 2 shows an actual state in which the pulley 7 on the rigid heat-insulating sunshade sliding cover 5 slides in the pulley groove of the C-shaped steel arched beam-pulley groove 1.

In fig. 3, the fixed heat-insulating sunshade cover 4 and the heat-insulating sunshade sliding cover 5 are 50mm extruded plates, the upper and lower surfaces of which are coated with a layer of anti-crack mortar and then coated with a layer of 0.3 mm hollow microsphere coating, the hollow microsphere coating is a hollow microsphere matrix layer formed by mixing 200-600 nm ceramic vacuum microspheres and 9 times of silicone-acrylic emulsion after drying, and the outer surface of which the sunlight can directly irradiate is coated with a layer of anti-radiation film (or reflective film). In summer, the outside of the hollow microsphere coating plate can reflect the heat radiation of the sun with a reflectance of more than 83 percent, and simultaneously emit most of the absorbed heat with a hemispherical emissivity of more than 87 percent, and the multilayer hollow microsphere matrix and the extruded sheet in the hollow microsphere coating further obstruct the conduction of heat flow entering mass points, thereby effectively reducing the temperature of the outer surface of a building and further reducing the indoor heat. In winter, the hollow microsphere coating on the inner surface reflects the indoor radiation heat back to the indoor, simultaneously radiates the heat on the inner surface of the plate to the indoor with higher emission ratio, and the multi-layer hollow microsphere matrix and the extruded sheet in the hollow microsphere coating plate further obstruct the conduction of heat flow entering mass points, thereby reducing the heat transfer from the indoor to the outdoor. The hollow ceramic microsphere coating (the American national aerospace agency, a novel space heat insulation reflective ceramic layer developed in 90 s in the 20 th century for solving the problem of heat transfer control of a space flight vehicle, the ceramic layer material is composed of a plurality of micro ceramic hollow particles suspended in inert latex, the material is an environment-friendly material with high solar reflectance, high hemispherical emissivity, low thermal conductivity, low heat storage coefficient and other thermal properties, the heat insulation reflective material is subjected to the technical conversion from the aerospace field to the industry and the construction industry abroad, and simultaneously is also converted from a thick layer to a thin layer, and the ceramic layer is more and more applied to buildings and industrial facilities all over the world at present).

Theories and practices prove that the heat release of a greenhouse lighting surface accounts for 80-90% of the overall heat release of the greenhouse, and the heat release of the underground and other places only accounts for 10-20%, so that the heat release problem in winter of the lighting surface and the overheating problem in summer of the greenhouse are solved, and the greenhouse plays a great role in the construction of agricultural production, sightseeing agriculture, ecological restaurants, industrial plants, commercial buildings, residential quarters, strong wind resistant buildings, modular movable simple houses and the like by virtue of advanced heat preservation, cooling, wind resistance and earthquake resistance of the greenhouse.
