Description

Technical Field

[0001] This utility model relates to the field of ancient tree protection technology, and in particular to an ancient tree ventilation and water regulation rejuvenation device. Background Technology

[0002] Ancient trees generally refer to trees over one hundred years old, possessing significant commemorative and ornamental value, and are relatively rare. Therefore, ancient trees are precious natural resources and living cultural relics, and their protection plays a vital role in scientific and cultural research and the development of urban landscaping. However, in the practice of ancient tree protection, the root system has been found to be a critical issue. Ancient tree roots need to absorb sufficient air and water to grow normally. However, some ancient trees grow in poor soil environments, lacking proper aeration and water permeability, leading to stunted growth and gradual weakening. One existing solution is to use an aeration device to inject high-pressure gas into the soil, loosening and aerating it. However, the roots of some trees are relatively fragile, and the vibration during aeration can easily damage them. Furthermore, this maintenance method is costly. Therefore, a novel aeration and water regulation device for ancient trees is needed to continuously provide sufficient air, water, and nutrients to the tree roots. Utility Model Content

[0003] The purpose of this invention is to provide a device for aerating and rejuvenating ancient trees by regulating water, which solves the problems of existing aeration devices that easily damage tree roots and have high maintenance costs.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0023] like Figure 1 The aforementioned ancient tree ventilation and water regulation rejuvenation device includes a water-storage and ventilation pipe 1 buried underground. The water-storage and ventilation pipe 1 is positioned close to the tree roots, such as... Figure 2As shown, the water-storing and ventilating pipe 1 includes an inner pipe 11 with pores on its body, and an impermeable outer pipe 12 wrapped around the lower outer wall of the inner pipe 11. A first vent pipe 2 and a second vent pipe 3 are respectively connected to both ends of the water-storing and ventilating pipe 1, and the upper ends of both the first vent pipe 2 and the second vent pipe 3 extend beyond the ground. In this utility model, the first vent pipe 2, the water-storing and ventilating pipe 1, and the second vent pipe 3 are arranged in a U-shape when viewed from the side.

[0024] Because the gap in the inner tube 11 is relatively large, in order to prevent soil from falling into the tube body through the gap in the inner tube 11, a thin layer of non-woven fabric 13 is wrapped around the outer wall of the water storage and ventilating tube 1 and tied tightly. Since the non-woven fabric 13 itself is also breathable, it can ensure the breathability of the entire water storage and ventilating tube 1.

[0025] To ensure good air permeability and drainage, the inner tube 11 is a blind drain pipe. The blind drain pipe is a three-dimensional porous material made by heating and melting thermoplastic synthetic resin, extruding fiber filaments through a nozzle, stacking them together, and fusing their joints. It can not only provide enough oxygen to the tree roots, but also drain excess water out of the pipe.

[0026] In order to retain a certain amount of water and fertilizer as needed, the outer tube 12 is a corrugated pipe cut into an arc structure, with the arc opening of the outer tube 12 facing upwards. Figure 2 As shown, in this embodiment, the outer tube 12 can be cut into a semi-circular arc structure as needed.

[0027] To achieve a temperature difference between the inside and outside air, the first vent pipe 2 extends above the ground at a greater height than the second vent pipe 3. Typically, there is a temperature difference between the inside of the pipe outside the ground and the inside of the pipe underground.

[0028] In addition to setting the first vent pipe 2 to extend above the ground at a greater height than the second vent pipe 3, a non-powered wind cap 4 is connected to the upper end of the first vent pipe 2. This non-powered wind cap 4 can be driven in two ways. The first way is by natural wind power. When external natural wind blows across the non-powered wind cap 4, the blades of the cap will rotate under the force of the wind. The centrifugal force generated by this rotation creates a negative pressure zone around the wind cap, meaning the air pressure inside the wind cap is lower than the air pressure inside the pipe. Due to this pressure difference, air inside the pipe is drawn into the wind cap and expelled outside, thus achieving ventilation. The second way is when there is a temperature difference between the outside and the underground. Through the principle of hot and cold air convection, the blades of the non-powered wind cap rotate, further accelerating the airflow inside the pipe. At the same time, the non-powered wind cap 4 itself also prevents a large amount of rainwater from entering the pipe.

[0029] like Figure 3 and Figure 4As shown, in order to increase the amount of air transported to the underground and effectively reduce rainwater intrusion, and to maximize the effect of the narrow opening, a tree rejuvenation device 5 is fitted on the upper end of the second ventilation pipe 3.

[0030] The tree rejuvenation device 5 includes a rejuvenation tube 51 fitted onto the second ventilation pipe 3. A cap 52 is provided at the upper end of the rejuvenation tube 51. The rejuvenation tube 51 and the cap 52 are detachably and securely connected via a threaded structure. This detachable connection facilitates deep irrigation by manually injecting water and fertilizer during dry periods. Excess water and fertilizer can overflow from both sides of the arc-shaped outer pipe 12, preventing excessive water accumulation.

[0031] In order to allow air to enter the ventilation hole 22 from all directions and to exert the effect of the narrow opening, the cover 52 is provided with several sets of fan-shaped louvers 53; in order to allow air to enter from all directions, the louvers 53 are provided with ventilation slots 54.

[0032] To facilitate rainwater drainage, the louvers 53 are tilted to the lower left at a certain angle, and the ventilation slots 54 are located on the right side of the louvers 53.

[0033] To prevent rainwater from flowing into the ventilation channel 54, a water-blocking strip 55 is also provided on the lower part of the ventilation channel 54 to prevent rainwater from entering the ventilation channel 54.

[0034] The arrangement of this utility model:

[0035] Ring installation method: such as Figure 5 As shown, after avoiding the large roots on both sides of the tree, dig wells about 1 meter deep on each side. Then, run water storage and ventilation pipes horizontally through the bottom of the wells. The pipes are arranged in a crisscross pattern with the tree roots. Three sets of arc pipes can be made around the roots of each tree.

[0036] Radial installation method: such as Figure 6 As shown, a rejuvenation trench can be dug directly on the side of each major root system, and pipes can be installed in the trench, and then the substrate fertilizer can be backfilled.

[0037] In the description of this utility model, it should be understood that terms such as "upper", "lower", "front", "rear", "left", "right", "bottom", "inner", "outer", "one end", "one side", "both ends", "both sides", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0038] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
