Description

Technical Field

[0001] This utility model belongs to the field of plant cold protection technology, and in particular relates to a cold protection device for trees in green belts. Background Technology

[0002] In cold winter regions, trees in green belts, especially newly planted trees or those with poor cold resistance, are often damaged by severe weather such as low temperatures, freezing, frost, or strong winds, resulting in withered branches and leaves, cracked bark, or even the death of the entire tree.

[0003] Currently, trees are covered with frost protection covers to block the cold wind. The covers are placed from the top of the tree, but when covering the trees from top to bottom, it is not easy to operate because the branches are spread outwards, and the branches are easily damaged. In addition, the frost protection covers made of plastic film will become brittle and tear when exposed to ultraviolet rays, rain and snow for a long time, lose their heat insulation performance, and cannot be reused, thus increasing the cost of greening maintenance.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention. Example

[0020] This embodiment describes a cold-proof device for trees in green belts, such as... Figure 1 , Figure 2 and Figure 3 As shown, it includes two protective plates 2 that are hinged together. The two protective plates 2 are connected by a connecting component. A protective cover 6 for covering trees is provided on the top of the two protective plates 2. A through groove is provided on the protective cover 6 along the central axis of the two protective plates 2 to divide the protective cover 6 into two parts. A first zipper 9 for connecting the two parts of the protective cover 6 is provided at the through groove. The protective cover 6 includes a heat insulation layer, a heat insulation layer is provided on the outer layer of the heat insulation layer, a waterproof layer is provided on the outer side of the heat insulation layer, and a moisture-proof layer is provided on the inner side of the heat insulation layer.

[0021] Two protective plates 2 are hinged at their rear sides. The two protective plates 2 have an arc-shaped structure. When their corresponding surfaces are pressed together, they form a tubular structure. The two protective plates 2 are connected by a connecting assembly, which includes two fixing plates. A fixing plate is fixed to the front side of each of the two protective plates 2. The two fixing plates are pressed together. One fixing plate has several first threaded holes, and the other plate has second threaded holes corresponding to the first threaded holes. Screws are sequentially threaded into the first and second threaded holes, connecting the two fixing plates and making the two protective plates... The two plates are fixed together; they can also be connected by bolts and nuts. The two arc-shaped protective plates 2 wrap around the tree trunk to protect it. The protective plates 2 are made of high-density polyethylene with reinforcing fibers. Their rigid structure can effectively block cold waves and strong winds from directly invading the tree trunk, reducing the risk of low-temperature freezing damage. They are especially suitable for extreme winter weather. The material has a certain degree of heat insulation, which can slow down the sudden drop in temperature around the tree trunk. The material is more resistant to chemical corrosion and damage. It is not easy to age after long-term contact with de-icing agents, which extends its service life and allows it to be reused many times.

[0022] The through-slot extends from the bottom front side of the protective cover 6 through the top of the protective cover 6 and finally to the bottom rear side of the protective cover 6. The protective cover 6 is divided into two parts along the central axis between the two protective plates 2 through the through-slot. The bottom of the two parts is fixed to the top of the protective plates 2 respectively. A first zipper 9 is provided at the through-slot between the two parts of the protective cover 6, and the two parts of the protective cover 6 are connected by the first zipper 9. In actual production, one side of the through-slot may not extend to the bottom of the protective cover 6, so that the protective cover 6 can be opened into two parts through the through-slot. The bottom connection of the protective cover 6 is fixed to the two protective plates 2, thereby connecting the two protective plates 2. This ensures the stability of the connection between the protective cover 6 and the two protective plates 2, and does not affect the fact that after the two parts of the protective cover 6 cover the tree from both sides, the two parts are connected by the first zipper 9, so that the protective cover 6 protects the tree and prevents the tree branches from breaking. The protective cover 6 is also more convenient to cover the tree.

[0023] The protective cover 6 includes an insulation layer made of insulation cotton. In low-temperature winter environments, the insulation cotton can effectively block the direct contact between cold air and trees, reducing the risk of frost damage. It can stabilize the temperature around the trees and alleviate the growth pressure caused by excessive day-night temperature differences. Moreover, the insulation cotton is a pollution-free and environmentally friendly material with no toxic residues on trees. It can be reused or recycled, reducing the cost of greening maintenance.

[0024] The outer side of the insulation cotton is covered with a heat insulation layer made of polyvinyl chloride (PVC). This material blocks external temperature changes, resists ultraviolet aging, and is suitable for long-term outdoor use. It can stably protect trees, especially in rainy or heavily polluted urban environments. This material can be bent to wrap irregular tree trunks and, when combined with the insulation cotton, forms a seamless protective layer, creating a double temperature control barrier to prevent local intrusion of cold air.

[0025] A waterproof layer is adhered to the outside of the insulation layer. The waterproof layer is made of polyethylene cold-proof film material, which has high light transmittance, can absorb solar energy and reflect heat, making the temperature around the tree higher than the environment, effectively preventing frost damage; it completely blocks rain and snow penetration, preventing the insulation cotton from getting damp and failing, while reducing the risk of tree rot caused by water accumulation; the polyethylene cold-proof film uses anti-ultraviolet additives, which can effectively delay the aging of materials caused by sunlight exposure, and has excellent puncture and tear resistance, can resist the friction of branches or the chewing of animals, and can be reused many times.

[0026] A moisture-proof layer is adhered to the inside of the insulation layer. This moisture-proof layer is made of fiber cloth. This structure can block the penetration of external liquid water while maintaining breathability, preventing the bark from suffocating and rotting due to excessive sealing. In winter, it can absorb condensation on the surface of the trunk, preventing freezing and cracking damage. Insect and fungicide agents are added to the fiber cloth to inhibit common pathogens such as canker bacteria, improving the survival rate of trees. In rainy southern regions, an anti-mildew coating can be applied to the inside of the fiber cloth. In frigid northern regions, the fiber cloth and insulation cotton can be thickened.

[0027] This embodiment further illustrates the technology. The lower section of the protective cover 6 is provided with a tensioning channel 4, and a tensioning rope 5 for tightening the protective cover 6 is threaded through the tensioning channel 4. The tensioning channel 4 is glued or sewn onto the outer wall of the lower section of the protective cover 6, and the tensioning rope 5 is threaded through the tensioning channel 4. By tightening the tensioning rope 5, the lower section of the protective cover 6 is collected through the tensioning channel 4, so that the lower section of the protective cover 6 is fixed to the tree trunk, thereby enhancing its stability, preventing strong winds from overturning the protective cover 6, and better protecting the tree.

[0028] This embodiment further explains the technology. Both protective plates 2 have grooves on their tops, and extension plates 3 are embedded within these grooves. The extension plates 3 have an arc-shaped structure and a limiting plate on their top. The top of the limiting plate 3 is connected to the bottom of the protective cover 6. The extension plates 3 move up and down within the grooves of the protective plates 2. Threaded holes communicating with the grooves are provided on the protective plates 2, and screws are threaded into these holes. The tightening end of the screw abuts against the side wall of the extension plate 3, thereby fixing the position of the extension plate 3 and adjusting the protective plates 2 to the protective cover. The distance between 6 makes the lengths of the protective plate 2 and the extension plate 3 more suitable for trees of different heights; the inner wall of the groove is provided with a sliding groove, and a limiting block 10 is provided in the sliding groove to slide up and down and is fixed to the bottom of the extension plate 3; the inner walls of the left and right sides of the groove are provided with sliding grooves, and a limiting block 10 is provided in the sliding groove to slide and is welded or glued to the bottom of the extension plate 3. The sliding cooperation between the limiting block 10 and the sliding groove makes the extension plate 3 move more smoothly in the groove, and also further limits the position of the extension plate 3 to prevent it from falling out of the groove; and the extension plate 3 is made of the same material as the protective plate 2.

[0029] This embodiment further illustrates the technology. The protective plate 2 has a base plate 1 at its bottom. The base plate 1 is welded or glued to the bottom of the protective plate 2. The bottom of the base plate 1 is in contact with the ground. The base plate 1 can enhance the stability of the protective plate 2 and make it better wrap the tree trunk. The bottom of the base plate 1 is provided with a number of nails 11 that are inserted into the soil. The base plate 1 is welded or glued to the bottom of the base plate 1 to insert the base plate 1 into the soil, thereby improving the stability of the base plate 1 on the soil and enhancing its wind resistance.

[0030] This embodiment further illustrates the technology. The protective cover 6 has a fixing groove, and an observation window 7 is provided at the fixing groove. The observation window 7, made of transparent material, is provided at the fixing groove on the protective cover 6. The observation window 7 is made of TPU soft plastic, which has low temperature resistance and remains elastic at low temperatures to avoid brittleness. It can withstand repeated bending in extremely cold environments with a low deformation rate. It has good light transmittance, ensuring a clear view of the growth of trees inside the protective cover 6. It also has tear resistance, resisting scratches from sharp objects such as ice crystals or branches.

[0031] The observation window 7 is connected to the fixing groove via a second zipper 8. The second zipper 8 is glued or sewn onto the fixing groove. By opening the second zipper 8, the observation window 7 can be opened, allowing airflow to exchange between the inside and outside of the protective cover 6. This can regulate the humidity inside the protective cover 6, reduce the temperature difference between the inside and outside of the protective cover 6, reduce water mist adhering to the observation window 7, prevent condensation from accumulating and causing mold growth, and ensure continuous photosynthesis of the plant. Moreover, when in use, it is not necessary to fully open the observation window 7; simply pull the second zipper 8 open slightly to create a certain gap between the observation window 7 and the protective cover 6.

[0032] In practical use, the tree trunk is wrapped with two protective plates 2, which are then fixed together using connecting components. The two parts of the protective cover 6 are then wrapped around the tree branches from both sides. The two parts of the protective cover 6 are connected using the first zipper 9, thus protecting the tree. The moisture-proof layer of the protective cover 6 blocks external moisture and prevents frost damage. The insulation layer outside the moisture-proof layer effectively blocks low temperatures, creating a stable temperature environment around the tree. The heat insulation layer outside the heat insulation layer reduces moisture evaporation and enhances the heat insulation effect. The waterproof layer outside the heat insulation layer prevents rainwater penetration, reducing the risk of frost damage and providing better insulation and cold protection for the tree. The multi-layered protective cover 6 is more durable and can be reused multiple times.
