Description

Technical Field

[0001] This utility model relates to the technical field of tree cold protection devices, and in particular to a tree cold protection device. Background Technology

[0002] With increasing public awareness of ecological environment, urban greening and landscaping have flourished. Whether it's street trees lining city streets or ornamental trees in parks and residential areas, they have become an important part of the urban ecosystem. Low winter temperatures pose a significant threat to tree growth, potentially causing frost damage, bark cracking, branch dieback, and even death. In northern regions, winter temperatures often drop to minus ten degrees Celsius or even lower. Some cold-sensitive tree species, such as camphor and magnolia, are easily damaged by frost if effective cold protection measures are not taken, affecting their survival and aesthetic appeal. Therefore, protecting trees for the winter has become a crucial aspect of tree maintenance. This is a key aspect that has driven the research and application of tree frost protection devices. In recent years, global climate change has led to an increase in extreme weather events, more intense fluctuations in winter temperatures, and longer periods of low temperatures. Some regions that were originally mild in winter have also experienced rare severe cold weather, which puts trees under greater pressure to protect themselves from the cold. Traditional methods of frost protection, such as simply wrapping trees with straw or applying lime water, are no longer sufficient to cope with increasingly complex climate conditions. In some southern regions, occasional strong cold air attacks can cause severe frost damage to local trees. This has prompted people to seek more efficient and reliable tree frost protection devices to enhance the trees' ability to withstand severe cold.

[0003] A search revealed Chinese Patent Publication No. CN210477067U, which discloses a tree frost protection device. The device includes a frame for surrounding the tree, a frost-proof cloth covering the sides of the frame, a sill at the top of the frame, and Velcro fasteners on the sill. The frame comprises a main frame with one open side and a side frame detachably connected to the side of the main frame with the open side. One side of the side frame is pin-connected to the main frame, and a side of the side frame parallel to the pin connection is detachably connected to the main frame. This application enables time-saving and labor-saving frost protection work for trees in gardens. While these methods can improve cold protection, the extent and location of frost damage vary depending on the tree's height. The tops and outer branches of tall trees are more susceptible to frost damage due to their larger exposed area to cold air, while low shrubs, being closer to the ground, are more affected by cold air from the ground. Traditional cold protection methods are insufficient to provide comprehensive and targeted protection for trees of different heights. Simply applying lime water cannot provide adequate cold protection for the upper branches of tall trees, nor can it effectively solve the problem of cold protection for the parts of low shrubs close to the ground. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a tree frost protection device, which aims to improve the problem that trees of different heights suffer different parts and degrees of frost damage in the existing technology. The top and outer branches of tall trees are more susceptible to frost damage because they have a larger area exposed to cold air.

This threaded connection ensures the stability of the semi-circular sleeves and facilitates adjustment. Adjustment plates are slidably connected to the outer walls of multiple threaded shafts. These adjustment plates are designed to allow users to adjust the opening and closing degree of the semi-circular sleeves as needed. The design of these holes reduces the weight of the adjustment plates while providing additional adjustment options, making the adjustment process more flexible and precise.

[0012] The above technical solution describes a fixed column whose upper and lower ends are designed to be fixedly connected with protective pads. The purpose of these protective pads is to provide additional protection during the use of the fixed column to prevent external forces from directly acting on the outer wall of the fixed column, thereby extending its service life.
