The technical proposal adopted by the utility model for solving its technical problems is that a sunshade picnic heat preservation package comprises a package body, the top of the package body is provided with a circle opening and a cover connected with the opening through a zipper, two symmetrical straps are arranged on both sides of the package body, and an integrated plastic skeleton is arranged on the side wall and the bottom of the package body. The plastic skeleton comprises a chassis matched with the bottom of the inclusion body and a support bar supporting the four corners of the inclusion body vertically around the chassis. The inner wall of the inclusion body is provided with an aluminum film thermal insulation lining layer, which can be used for high temperature heat preservation and low temperature heat preservation, and the effect is good. One corner of the inclusion body is provided with a cylindrical groove arranged in the inclusion body, the bottom of the groove is provided with a base, and the base is provided with a retractable umbrella handle. The retractable umbrella handle is provided with a sunshade, which can be used as an umbrella when the sun is strong or it rains.
First of all, car shading can effectively reduce the temperature inside the car. Sunshade is a combination of multi-layer bubble film and aluminum foil, which belongs to a kind of plastic products. Aluminum foil has the ability to reflect light, thus reducing thermal radiation and low thermal radiation conductivity. When the sun shines on the sunshade, some of the heat will be blocked and the ultraviolet light will be reflected by the aluminum foil.
Raise the level of mechanized production and liberate labor productivity. First of all, from the environmental control system of multi-span greenhouse, electric sunshade, electric film (window opening) ventilation, electric thermal insulation quilt, electric fan water curtain cooling have been realized, and the environmental control ability of greenhouse is more stable and reasonable. work efficiency is higher, do not need manual operation, just press the switch of the distribution cabinet. Looking at the agricultural production in some backward areas ten years ago and even now, this is a great progress for facility agriculture in our country. Secondly, the interior of our multi-span greenhouse can be equipped with mechanized automatic sprinkler irrigation, integrated water and fertilizer machine, automatic seeder, and even Internet of things control software are now very common systems. greatly improve the production efficiency and achieve precision irrigation and fertilization, water-saving and fertilizer-saving, soilless cultivation and other protection of soil from pollution.
Placing the sunshade on the central console blocks the bright light to avoid the reflection of the sun (after the sun shines on the control panel of the car, some light reflects some light again, which enters the driver of the eyes. It is very dangerous to blur the body in this case). To a certain extent, the view of the solar light to the owner is that at this level, the use of the solar distribution pad can effectively protect the safety of the owner; in addition, the solar distribution pad can also reduce direct contact between the central console and the sun. When touching the power supply, the owner will not feel very hot.
When the sun shines on the sunshade, some of the heat will be blocked, and the ultraviolet light will be reflected by the aluminum foil. Car sunshade can prevent leather seats and dashboards from being damaged by ultraviolet rays. Direct exposure to the sun will make the temperature in the car as high as 70 degrees. Not only the shell of the central console is easy to deform, instruments and other equipment on the dashboard are also damaged by high temperature, such as aging components, pin soldering, etc., sunshade can effectively avoid direct sunlight.
2. Sunshade. The membrane structure parking shed adopts polycarbonate material with high impact resistance, and its strength is about 200 times that of glass. The raw materials are imported from Germany and processed in China. Through the double-sided co-extrusion process, the anti-ultraviolet material (UV) is added, which can effectively block more than 98% of the ultraviolet rays, protect the car surface paint, effectively control the continuous rise of the interior temperature, and in direct sunlight. The temperature in the car can reach more than 60 ℃ and can be effectively reduced to about 40 ℃ after installation. At the same time, it also has flame retardant effect, and can be used normally for more than 30 years in the environment of-30 ℃ to 60 ℃ (137 ℃ thermal deformation). The downcomer is made of high-strength aluminum alloy and has a unique user-friendly design to avoid the second pollution to the car and you when the roof water falls to the ground. The structure is reasonable and easy to clean, and it is convenient for the membrane structure parking shed to remove dirt in the pipe.
