Do a good job in greenhouse reinforcement, heat preservation and warming. Such as using double film to cover cultivated mushrooms, press the outer plastic film to prevent air leakage. Check and reinforce the scaffolding to prevent heavy snow from collapsing. When necessary, measures such as removing the covering (such as the outer sunshade net) should be taken to reduce the pressure of the mushroom shed and reduce the loss.
There is no bulge on the surface of various devices in the car cockpit, the material is soft and elastic, and the sharp corners, protruding edges and protruding parts can be reduced as much as possible, which can reduce the injury suffered by the passengers in the event of collision. The range of interior softening includes prominent accessories such as steering wheel, dashboard, side circumference, roof, seat, floor and sunshade. The steering wheel of some cars can contract during a collision, and some seats have headrest to prevent head injury when the rear is hit. These are all designs that can improve the safety of the car.
In the internal thermal insulation system, when the greenhouse or indoor temperature drops to the set low temperature limit at night, the thermal insulation quilt is turned off, the heat preservation of the greenhouse is strengthened, the ground radiation heat loss is reduced, the heating energy consumption is reduced, and the operating cost of the greenhouse is greatly reduced; the shade curtain can be opened during the day to make the greenhouse fully daylighting. The working principle is the same as that of internal sunshade, which is made of a lightweight quilt that does not absorb water and weighs between 100 and 150 grams.
First, the applicable extension width is 3, which uses a mechanical device and a crank arm device system. Under the action of spring, it can also be used for ceiling installation, light steel keel and other hard wall installation, brick wall motor control, the following is the awning fabric introduction. 00 meters, manual crank control through different transmission systems. The whole crank arm group is realized by an arm block, which can be adjusted in parallel with any precision of ~ 70 degrees. The characteristic of the 00-meter, half-box curved arm awning is that the sunshade fabric can be incorporated into the hood. Bolts and screws are made of high-quality stainless steel, applicable length is 6, can be applied to concrete, produce telescopic tension, infrared remote control and wind and rain sensor control, the structural frame adopts degree space aluminum. Wood. The common glass with good shading performance is endothermic glass, heat reflection glass, low radiation glass.
The beneficial effect of the utility model is that the sunshade picnic insulation bag of the utility model not only has excellent high temperature heat preservation and low temperature heat preservation effect, but also has a skeleton inside the package body, which can be used as a stool, and is built with detachable sunshade umbrellas, which is more suitable for carrying out, more powerful in function and more practical.
For this reason, the competent departments of agriculture and forestry in many places have issued various measures to require farmers to do a good job in the prevention and remediation of crops in order to deal with the “late spring cold.” For example, for the vegetable greenhouse, the relevant departments stipulate that “when the temperature in the greenhouse is below 0 ℃ for a long time, straw bags, non-woven cloth, sunshade net and other mulch should be added in the greenhouse at night to prevent frost injury and take basin fire or fire temporary heating. At the same time, open fire can not be used when heating to prevent smoke damage, it is necessary to set up a flue to discharge harmful gases outdoors. Strengthen the coverage in time to promote heat preservation and anti-freezing. ”
c. Functional class. Including car body insulation materials, anti-collision fillers, dashboards, sundries, indoor shelf panels or rear windowsill panels, sunshade panels, wheel cover covers, engine cover covers, etc.
