It can reduce the harm of cold current. When the temperature in the shed is below ℃ for a long time, the mulch such as straw bag non-woven sunshade net should be covered in the greenhouse at night to prevent frost damage and take basin fire or furnace fire to heat temporarily. Open fire can not be used when heating, in order to prevent smoke damage, it is necessary to set up a flue to put harmful gases outside, focusing on the heat preservation and anti-freezing of vegetables and seedlings in the greenhouse. For eggplant seedlings which are in the early stage of raising seedlings, measures such as artificial light supplement and temperature increase can be taken. Prevent seedling frost injury or overgrowth; cover should be removed properly during rainy days.
First, automatic telescopic sunshade, thermal insulation and cooling, the seats of the car are generally leather, and long-term exposure to the sun will lead to excessive temperature in the car, which can easily lead to aging and hardening of the leather material in the car. but now the car sunscreen tools can play a good role in thermal insulation and cooling to protect the car. Car automatic telescopic sunscreen front and rear window shade this is a very popular automatic windshield sunscreen, the installation is very simple and convenient, put it away directly when not in use, and open it when you need it. When the car is parked in the sun, it can protect against ultraviolet rays and prevent the car from getting too hot.
First, the sanitary disinfection of the enclosure should be done well. The manure should be cleaned up in time every day and transported to a place far away from the cattle farm for accumulation and fermentation, and the cowshed should be disinfected regularly, usually once every 3-5 days in summer and autumn, and once every 7-10 days in winter and spring. Second, strengthen window ventilation to reduce toxic and harmful gases such as humidity, dust, ammonia and carbon dioxide in the enclosure. Third, to ensure that the barn temperature is suitable, sunshade net is set up to cool down in summer, and greenhouse is built to keep warm in winter, only beef cattle can grow better at a suitable temperature.
More installation method has a double-sided detachable, double-sided detachable installation node, which is a good node for bracket installation. At present, the maintenance of ultra-polymer photovoltaic support bearings is developing rapidly. If there is no such use of pressure and mechanical fixation, it is likely to produce a lot of defects. Such as irregular axial loosening, axial pressure deformation, installation collision, photovoltaic support instability and so on. Erguna connected greenhouse tube structure of a variety of assembly plants can use these pipes, electrical equipment to form a workspace, does not require a large amount of investment. This automatic device mainly relies on the computer as the control center to control the facilities such as skylight, sunshade, heat preservation, wet curtain / fan cooling, spray drip irrigation or drip irrigation, seedbed and so on. Of course, the automatic device can not only rely on the control of the computer, it also has acquisition and control.
Seat category: including car seat cushion, seat back, seat cover, seat fabric and headrest and other materials. Interior decoration: including interior floor, door guard, side guard, rear guard, roof lining, curtains and floor coverings, etc. Functional category: including car body thermal insulation materials, anti-collision fillers, dashboards, glove boxes, indoor shelf panels or rear window panels, sunshades, etc.
Such as sunshade panels, exterior insulation panels and local areas where the temperature between the doors is easy to rise. In the field of temperature, polypropylene foam is more advantageous than polyethylene foam and polystyrene foam, for example, in addition to light weight, because polypropylene foam has higher heat resistance, epp materials are in higher demand. Why is the substitution of epp materials so great in the automotive field?
After the rubber joint is subjected to pressure for the first time (such as installation and pressure test, etc.) or before it is reactivated after long-term shutdown, the bolt should be tightened again and put into operation. The effective expansion deformation of the bellows of the working main body is used to absorb the size changes caused by thermal expansion and cold shrinkage of pipelines, ducts and containers, or to compensate the axial, lateral and angular displacement of pipelines, ducts, containers, etc. The use or storage of Weihai integrated water processor should avoid high temperature, ozone, oil and acid-base environment. Sunshade racks should be built for pipes used outdoors or facing the sun and the wind, and exposure, rain and wind erosion are strictly prohibited. Paint and winding thermal insulation materials are strictly prohibited on the joint surface. Due to the aging problem of rubber products, it should be inspected and replaced in time. The benefits of this: first of all, the working pressure: the commonly used rubber joint pressure has the same size.
In terms of interior space, Keluwei is equipped with a central console and dashboard with a multi-functional black-and-white display driving computer, a practical center console with a variety of storage spaces, a sunshade for the side windows of the passenger cabin, a comfortable roof lighting system, and a car body roof. The four reading lights in the passenger cabin provide enough light for passengers to read, and welcome pedals with lighting function and vehicle name logo Adds elegance to the interior space.
This kind of flower planting greenhouse is widely used in most areas, especially in the south. The single-family arch shed is mainly made of plastic-coated steel pipe or galvanized steel pipe, the surface is covered with film, and air vents are added on both sides. The utility model has the advantages of simple structure, low cost, easy construction and maintenance, long service life and strong resistance to wind and snow load. Its biggest deficiency is its low heat preservation capacity and high operating cost in winter, so it is suitable for breeding non-tropical flowers with low temperature requirements. Of course, we can add two-layer film on the original basis, increase the curtain machine quilt and other thermal insulation equipment, sunshade can effectively improve the arch shed temperature.
≥ 9 million pixels, including high-definition integrated embedded camera, high-definition lens, outdoor shield, camera built-in network signal lightning protector, power adapter and so on. GMOS deep learning chip is used. Support front window pendant, annual inspection logo, smoking, driver face recognition, cab face matting, sunshade recognition and other detection functions. The face matting function of the master and co-driver is supported. In a single-lane scene, the location, speed, vehicle model, driving direction and license plate type are supported as trigger conditions for snapping. Support human detection, tracking, capture, support front and back capture; in the same video screen, up to 100 moving human targets can be detected at the same time. On the premise that the bayonet detection of human body / face is configured with 3 snapshots, the best image is supported for re-screening.
