Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of open coal mine, in particular to a heat preservation and water storage device for vegetation planting in lignite mine area. BACKGROUND

[0002] Under the background of global energy supply and ecological protection coordinated development, although lignite open mining guarantees energy demand, it causes ecological damage. Every 10,000 tons of lignite mining causes 0.2-0.3 hectares of land subsidence and vegetation damage, leading to soil structure fragmentation, soil erosion aggravation, and sharp reduction of biodiversity. In high-latitude or high-altitude cold regions, ecological restoration faces more severe challenges. The average annual temperature in such regions is low, the extreme low temperature can reach minus several dozen degrees Celsius, the soil freezing period lasts for 6-8 months, and the growing season is only 3-4 months. When traditional reclamation uses conventional grass seeds and planting methods, the seed germination rate is less than 30%, and the seedling survival rate is as low as 10%-20%, which cannot meet the ecological restoration demand. At the same time, the cold mining area also has problems such as drought and strong wind, and the soil has poor water and fertilizer retention capacity and low rainfall conversion efficiency, which is prone to "dry and frozen superposition" phenomenon, and strong wind can accelerate soil water evaporation and cause dust, further damaging seedling roots. In addition, the existing reclamation technology only focuses on vegetation survival, ignores the coordinated demand of ecological restoration and carbon emission reduction, lacks environmental regulation design for the whole process of vegetation growth, and a large number of seedlings die, resulting in the lack of carbon fixation carriers, which cannot realize carbon sequestration by using the photosynthesis and root carbon fixation of vegetation, and cannot help the mine area to cope with global climate change.

[0022] Embodiment As Figures 1 to 4 shown, the present embodiment provides a root heat preservation and water storage device for planting cold-resistant vegetation in a lignite mining area, which comprises a ring-shaped protective cylinder 1, a ring-shaped heater 2 is installed on the inner side of the ring-shaped protective cylinder 1, and a shielding ring net 3 is installed on the top end of the ring-shaped protective cylinder 1.

[0023] Among them, the inner side of the ring-shaped protective cylinder 1 is provided with a water storage ring cavity 11, a plurality of drainage holes 12 are opened on the inner wall of the ring-shaped protective cylinder 1, and the water storage ring cavity 11 irrigates the soil in the space on the inner side of the ring-shaped protective cylinder 1 through the drainage holes 12.

[0024] It should be noted that the ring-shaped protective cylinder 1 described in this embodiment is open at the top and bottom, and the roots of the vegetation can continue to grow downward.

[0025] The shielding ring net 3 is located at the top opening position of the water storage ring cavity 11, the bottom of the shielding ring net 3 is provided with a shielding ring 31, the shielding ring 31 is installed on the inner wall of the water storage ring cavity 11, and a plurality of through holes 311 are opened on the shielding ring 31.

[0026] One side of the ring-shaped heater 2 is connected with the internal space of the water storage ring cavity 11, and the ring-shaped heater 2 can heat the soil on the inner side and the water source in the water storage ring cavity 11 together.

[0027] Specifically, in operation, the annular protection cylinder 1 encloses the roots of the cold-resistant vegetation in the lignite mining area, the annular heater 2 on the inner side of the annular protection cylinder 1 can heat the inner side soil and the water source inside the water storage ring cavity 11 together, raise the soil temperature, create a warm environment for the roots of the vegetation, resist the cold of the mining area, prolong the growth season of the vegetation, improve the seed germination rate and seedling survival rate, the water storage ring cavity 11 can store rainwater, irrigate the soil in the inner space of the annular protection cylinder 1 through the drainage holes 12 opened on the inner wall, provide water for the vegetation, improve the drought condition of the mining area, and enhance the water retention capacity of the soil. The shielding ring net 3 prevents external impurities from entering the water storage ring cavity 11, and the shielding ring net 3 and the shielding ring 31 at the bottom can not only ensure a certain air permeability through the through holes 311 on the shielding ring 31, but also block strong winds, reduce soil water evaporation and dust, and protect the seedling root system. In this way, the growth environment of the vegetation is regulated from temperature, moisture, windproof and other aspects to ensure the growth of the vegetation, so that the vegetation can realize carbon sequestration through photosynthesis and root carbon sequestration, solve the problems of low seed germination rate and seedling survival rate in traditional reclamation in cold mining areas, poor soil water and fertilizer retention, strong wind damage to root system, and lack of ecological restoration and carbon emission reduction collaborative design, and help the ecological restoration and carbon emission reduction in the mining area to cope with global climate change.

[0028] In this embodiment, the annular distribution groove 13 is arranged on the inner bottom side of the water storage ring cavity 11, an electromagnetic valve 131 is arranged on one side of the annular distribution groove 13, the annular distribution groove 13 is in space communication with the drainage holes 12, and the annular distribution groove 13 is in space communication with the inner space of the water storage ring cavity 11 through the electromagnetic valve 131.

[0029] Specifically, when irrigation is needed, the electromagnetic valve 131 is opened, the water in the water storage ring cavity 11 enters the annular distribution groove 13, and then flows uniformly to the soil on the inner side of the annular protection cylinder 1 through the drainage holes 12 to supply water to the root system of the vegetation; when irrigation is not needed, the electromagnetic valve 131 is closed to stop water supply, precise control of irrigation is realized, water resource waste is avoided, precipitation conversion efficiency is improved, soil water retention capacity is enhanced, and the "dry and frozen superimposed" condition in the mining area is improved to provide stable water supply for the root system of the vegetation.

[0030] In this embodiment, the water permeable cotton 121 is arranged on the inner wall of each drainage hole 12 to prevent soil from entering the annular distribution groove 13 through the drainage hole 12.

[0031] Specifically, in operation, the water in the water storage ring cavity 11 enters the annular distribution groove 13 through the electromagnetic valve 131, and then irrigates the soil on the inner side of the annular protection cylinder 1 through the drainage holes 12. The water permeable cotton 121 arranged on the inner wall of the drainage hole 12 allows water to permeate while effectively blocking soil particles, preventing soil from entering the annular distribution groove 13, avoiding blockage of the drainage hole 12 and the annular distribution groove 13 due to soil accumulation, ensuring the smoothness of the irrigation waterway, and continuously supplying stable water to the root system of the vegetation.

[0032] In this embodiment, the inside of the annular protective cylinder 1 is provided with a temperature and humidity sensor 14, which is electrically connected with the annular heater 2 and the electromagnetic valve 131.

[0033] Specifically, the temperature and humidity sensor 14 inside the annular protective cylinder 1 monitors the temperature and humidity of the inside soil in real time. When the soil humidity is lower than the set threshold, the temperature and humidity sensor 14 sends an electric signal to the electromagnetic valve 131 to control the electromagnetic valve 131 to open, so that the water in the water storage ring cavity 11 flows into the soil through the annular shunt groove 13 and the drain hole 12 to supplement the water for the plant root system; when the soil humidity reaches the set threshold, the temperature and humidity sensor 14 sends an electric signal to control the electromagnetic valve 131 to close to stop water supply. Through such electrical connection and cooperative work, automatic and accurate control of soil irrigation is realized, irrigation operation is adjusted in time according to the actual temperature and humidity of the soil, and the suitability of the growth environment of the plant root system is guaranteed. Similarly, the annular heater 2 is controlled by the temperature and humidity sensor 14 to heat and stop.

[0034] In this embodiment, the bottom of the shielding ring 31 is provided with a plurality of one-way valves 32, and a plurality of through holes 311 correspond one-to-one with the plurality of one-way valves 32.

[0035] Specifically, when the external water source such as precipitation enters through the through hole 311 on the shielding ring 31, it will push the one-way valve 32 corresponding to the through hole 311 to open, so that the water source flows smoothly into the water storage ring cavity 11 for storage for subsequent irrigation of vegetation; when the water in the water storage ring cavity 11 has a tendency to flow outward, the one-way valve 32 will remain closed to prevent the water in the water storage ring cavity 11 from flowing outward through the through hole 311, thereby realizing effective collection and storage of the water source such as precipitation, and providing stable water reserve for vegetation growth.

[0036] In this embodiment, the inside of the top of the annular protective cylinder 1 is provided with an energy storage battery ring 4, the top end of the energy storage battery ring 4 is provided with two top racks 41, the inside of each of the two top racks 41 is provided with an arc opening 411, and the top end of each of the two top racks 41 is provided with a solar panel 42 for charging the energy storage battery ring 4.

[0037] Specifically, in operation, the energy storage battery ring 4 at the top of the annular protective cylinder 1 provides power support for various power components of the device, such as the annular heater 2, the electromagnetic valve 131, the temperature and humidity sensor 14, etc. The two top racks 41 are adapted to the stems of the vegetation through the inner arc opening 411, and are stably erected at the top end of the energy storage battery ring 4. The solar panel 42 installed at the top end can receive external solar energy and convert it into electrical energy to continuously charge the energy storage battery ring 4, ensuring that the energy storage battery ring 4 always maintains sufficient power. This design does not rely on external power supply, and uses the abundant light resources in the lignite mining area to achieve self-power supply, ensuring the stable operation of the device in the wild environment of the mining area, providing continuous power support for temperature regulation, precise irrigation and other functions of vegetation growth. In addition, the top rack 41 is detachable and convenient to replace, and the arc opening 411 of appropriate size can be replaced to adapt to the size of the vegetation.

[0038] The working principle of the present application is as follows: In operation, the annular protective cylinder 1 encloses the cold-resistant vegetation roots in the lignite mining area, the energy storage battery ring 4 at the top inside supplies power to the annular heater 2, the electromagnetic valve 131, and the temperature and humidity sensor 14, the top rack 41 is adapted to the stems of the vegetation through the arc opening 411, and the solar panel 42 at the top end converts solar energy into electrical energy to charge the energy storage battery ring 4. The temperature and humidity sensor 14 monitors the soil temperature and humidity in real time. If the humidity is low, the electromagnetic valve 131 is opened, and the water in the water storage ring cavity 11 flows into the soil through the annular shunt groove 13 and the drainage hole 12. The water-permeable cotton 121 in the drainage hole 12 prevents soil blockage. If the humidity meets the standard, the electromagnetic valve 131 is closed. When the temperature is low, the temperature and humidity sensor 14 controls the annular heater 2 to start, and at the same time, the soil and the water source in the water storage ring cavity 11 are heated. When it rains, the water pushes the one-way valve 32 into the water storage ring cavity 11 through the through hole 311 of the shielding ring 31 for storage. The shielding ring net 3 and the shielding ring 31 prevent wind and impurities and maintain air permeability, ensuring the growth of vegetation and assisting in ecological restoration and carbon emission reduction in the mining area.

[0039] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
