[0016] Step 1: Determine the winding method of the heat preservation water pipe according to the diameter and length of the tree trunk, and wind the heat preservation water pipe around the outer wall of the tree trunk so that it fits closely to the surface of the tree trunk;

[0017] Step 2: Pass the water inlet and outlet of the insulation water pipe through the through holes at the upper and lower ends of the insulation bag, and use the elastic properties of the insulation bag to tightly wrap it around the outside of the spiral insulation water pipe, with the upper and lower ends close to the tree trunk, pull the two sides of the insulation bag together, close them, and pull the zipper to fix the insulation bag;

The circulation pump of the water tank transports the heated hot water to the spiral insulation water pipe. The hot water flows in the spiral insulation water pipe, transferring heat energy to the tree trunk to form a thermal insulation layer. In the cold winter, the hot water circulation can effectively prevent frostbite of the tree trunk and provide insulation for the trees.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention utilizes solar energy to provide an environment for trees to keep warm and assist their growth. It fully utilizes solar energy as energy, does not consume traditional energy, reduces carbon emissions, and complies with the concept of energy conservation and environmental protection. The spiral water pipe is wrapped around the tree trunk to provide an additional insulation layer for the tree, effectively preventing the tree trunk from being frostbitten in the cold season. Through the circulation of hot water, it can also provide a suitable growth temperature for the trees and promote the healthy growth of the trees. The combined use of solar collectors and photovoltaic panels realizes the dual utilization of light energy: one part is converted into heat energy to provide insulation for the trees; the other part is converted into electrical energy to power the system's circulation pump, thereby improving the energy utilization efficiency and making the system more economical and efficient.

[0024] 2. The present invention is provided with a thermal insulation cover, and the thermal insulation cover adopts elastic fiber cloth as the elastic bonding layer, which can fit tightly against the tree trunk and the thermal insulation water pipe, providing good elastic adaptability, ensuring the close fit between the cover and the tree trunk and the thermal insulation water pipe, and effectively reducing heat loss. The thermal insulation layer adopts polyester fiber thermal insulation cotton, which can store a large amount of still air, effectively block the invasion of external cold air, keep the temperature around the thermal insulation water pipe stable, and provide excellent thermal insulation effect for the trees. The protective layer adopts polyester cloth, which can effectively block the strong wind from blowing directly on the tree trunk, keep the temperature around the tree trunk stable, and prevent rain or snow water from penetrating, keep the cover and the trunk dry, and avoid frost damage. At the same time, it has excellent wear resistance, can resist friction and wear in the external environment, and significantly extend the service life of the cover.

[0025] 3. The heat preservation device of the present invention adopts a convenient installation structure, and the installation process is efficient and convenient. First, the heat preservation water pipe can be bent and shaped because of the steel wire embedded in its inner wall, and can be flexibly wrapped around the outer wall of the trunk according to the diameter and length of the trunk. Then, the water inlet and the water outlet can easily pass through the through holes at the upper and lower ends of the heat preservation bag.
