Description

Technical Field

[0001] The invention relates to the technical field of ecological restoration, and in particular to a device for restoring vegetation in abandoned mine land. Background Art

[0002] Metal mining has a significant impact on the topography and may cause geological disasters. Therefore, restoring vegetation in abandoned mine sites helps stabilize the topography and reduce the occurrence of geological disasters. In addition, tailings ponds generated during mining are potential sources of soil and water pollution, and heavy metals and harmful substances in tailings ponds may spread to the surrounding environment through wind, water and other channels, posing a threat to the ecosystem and human health. Vegetation restoration can effectively reduce the exposed area of ​​tailings ponds and reduce the risk of soil and water pollution.

[0003] Due to the remote geographical location of abandoned mines, manual fertilization operations in subsequent vegetation restoration are not only time-consuming and labor-intensive, but also costly. These areas are often inconvenient for transportation, making it difficult to transport fertilizers and other necessary restoration materials. In addition, weather conditions in remote areas may be more severe, such as drought, strong winds or cold, which will increase the difficulty of manual operations and may affect the effectiveness of vegetation restoration. Therefore, it is necessary to propose a restoration device for vegetation in abandoned mines that can take into account the geographical location and climatic conditions of abandoned mines, and has high efficiency and adaptability. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a device for restoring vegetation in abandoned mine sites. Through soil moisture detection, rainwater group collection, fertilization and irrigation judgment and irrigation timing control, synchronous and intelligent irrigation and fertilization, as well as water-saving irrigation for vegetation restoration in abandoned mine sites, are achieved, thereby improving the efficiency of vegetation restoration.

[0005] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a device for restoring vegetation in abandoned mine land, comprising a vegetation blanket for laying shrub seeds and nutrient soil, a plurality of fixing holes are opened on the vegetation blanket, and fixing piles are detachably connected in the fixing holes, a first water collection component for collecting and storing rainwater is provided on the vegetation blanket, and the fixing piles are fixedly connected to the first water collection component;

[0006] The fixed piles all include, from top to bottom, a functional tube and a piercing tube for piercing the soil for fixing. The functional tube includes, from top to bottom, a water storage chamber, a fertilizer storage chamber for storing fertilizers required for grass irrigating, and a water delivery chamber for delivering water under the soil. The outer wall of the water storage chamber is provided with a second water collecting assembly for collecting rainwater. The water storage chamber is connected with the fertilizer storage chamber and the water delivery chamber respectively. The connection between the water storage chamber and the fertilizer storage chamber is fixedly connected with an electromagnetic valve, and the electromagnetic valve signal is connected with a control system. The fertilizer storage chamber is connected with a vegetation blanket, and a water-soluble film is provided at the connection between the fertilizer storage chamber and the vegetation blanket. A soil moisture sensor is fixedly connected to the bottom end of the piercing tube, and the soil moisture sensor is connected with the control system signal.

[0007] The technical principle of the above scheme is as follows: a vegetation blanket carrying pot grass seeds is laid on the abandoned mine land, a number of fixed piles are used to fix the vegetation blanket through a number of fixed holes, rainwater is collected by the first water collection component and the second water collection component, and the rainwater of the second water collection component is stored in the water storage cavity. The soil moisture content is then detected by a soil moisture sensor, and the moisture content data is received by the control system to analyze and determine whether irrigation and fertilization are needed, and the solenoid valve is controlled by signal to achieve irrigation and fertilization that meets the growth needs of shrubs and grasses.

[0008] The above scheme has the following beneficial effects:

[0009] 1. This scheme uses vegetation blankets for laying, quickly covering the abandoned mine land with a base layer designed for vegetation growth. The shrub and grass seeds are wrapped in the vegetation blanket for sowing, providing a solid support structure for the growth of vegetation. The pre-arrangement and spreading of seeds can ensure the uniform distribution of seeds and create an ideal growth environment for them.

[0010] 2. This solution integrates the first water collection component and the second water collection component, which can efficiently collect and store rainwater, provide the necessary moisture for the growth of vegetation and achieve the effect of water-saving irrigation. It performs precise irrigation according to soil moisture and fertilization time, which not only reduces the waste of water resources, but also enhances the self-sufficiency of the device, making the vegetation restoration process more sustainable and adapting to the unique geographical environment and climatic conditions of the abandoned mine site.

[0011] 3. In this solution, the piercing tube design of the fixed pile enables it to be firmly fixed in the soil, and the soil moisture sensor can collect the moisture content of the soil and transmit the moisture content information to the control system for identification and comparison. The operator can enter different soil moisture thresholds according to different terrain and soil conditions, so that the device can be widely used in vegetation restoration work in various mine wastes, such as slopes and environments with soft soil, thereby improving its versatility and practicality.

[0012] 4. Through the coordinated work of the control system and the solenoid valve assembly, the device can intelligently determine whether irrigation and fertilization are needed based on the data from the soil moisture sensor and the water level sensor. The intelligent management method not only improves the accuracy of irrigation and fertilization, but also saves water resources and fertilizers, reduces maintenance costs, and adapts to the problem that the remoteness of abandoned land is not conducive to artificial irrigation.

[0013] Furthermore, the first water collecting assembly includes a water collecting tank, a first water collecting cover is fixedly connected to the top of the water collecting tank, a pump assembly is fixedly connected to the water collecting tank, the water collecting tank is connected to a plurality of water storage chambers through the pump assembly, and the pump assembly is connected to the control system signal.

[0014] Beneficial effects: Through the combination of the water collection tank and the first water collection cover, rainwater or irrigation water can be collected efficiently, and then the water is pumped through the pump assembly to ensure smooth transmission of the water flow. The pump assembly is connected to the control system signal to achieve intelligent control of the entire water collection and water delivery process. Through the control system, the working state of the pump assembly can be accurately adjusted to meet different irrigation needs, which also helps to save water and reduce emissions.

[0015] Furthermore, the second water collecting components all include a second water collecting cover, the bottom end of the second water collecting cover is fixedly connected to the outer side wall of the water storage chamber, and the side wall of the water storage chamber is provided with a plurality of water inlets.

[0016] Beneficial effects: Through the fixed connection between the second water collecting cover and the outer wall of the water storage chamber, rainwater or irrigation water can flow directly into the water storage chamber, reducing the intermediate links of water flow transmission and improving the water collection efficiency. The several water inlets opened on the side wall of the water storage chamber allow water to enter the water storage chamber from multiple directions, further increasing the water collection area and water collection speed, ensuring that the water storage chamber can be quickly filled with water. In addition, due to the simple structure and reasonable design, daily maintenance and management work becomes more convenient. Users can easily check whether the water inlet is blocked and the water storage condition of the water storage chamber, thereby ensuring the normal operation of the system.

[0017] Furthermore, a water level sensor is fixedly connected to the inner wall of the water storage chamber, and the water level sensor is connected to the control system signal.

[0018] Beneficial effects: The water level sensor can monitor the water level changes in the water storage chamber in real time and accurately, ensuring that the system can understand the water level status in time. By connecting with the control system, the soil moisture sensor can achieve precise control of the irrigation system.

[0019] Furthermore, a fixing block is fixedly connected to the outside of the water storage chamber, and the fixing block is a "concave"-shaped structure.

[0020] Beneficial effect: The fixing block with a "concave"-shaped structure can fit more effectively with the outside of the water storage cavity, thereby improving the stability of the fixing pile and helping to prevent the water storage cavity from being deformed or damaged due to external forces during long-term use.

[0021] Furthermore, the vegetation blanket comprises an upper mesh layer, a plant fiber layer, a seed layer and a lower mesh layer from top to bottom, a gap is provided between the plant fiber layer and the seed layer, and the gap is communicated with the fertilizer storage cavity.

[0022] Beneficial effects: The laying of vegetation blankets can quickly cover a base layer that is conducive to vegetation growth on the abandoned mine land. Whether it is a slope or other severe terrain, the multi-layer design of the vegetation blanket can provide a stable support, uniform distribution of seeds and a good growth environment.

[0023] Furthermore, a water pipe is fixedly connected to the side wall of the water storage chamber, and one end of the water pipe away from the water storage chamber is connected to the water storage chamber, and the connection point between the water pipe and the water storage chamber is located at the top of the side wall of the water storage chamber.

[0024] Beneficial effect: The design of the water pipe allows the excess water to flow directly into the water delivery chamber after the water storage chamber is full and directly irrigate the soil, reducing the risk of poor growth of seeds due to excessive irrigation.

[0025] Further, the control system includes a preset module, a collection module, a drought judgment module, a water storage judgment module and a drive module;

[0026] A preset module for recording different soil moisture thresholds entered by operators according to different terrains;

[0027] The acquisition module is used to collect the moisture content of the soil through a soil moisture sensor and to collect the water level data in the water storage cavity through a water level sensor;

[0028] The drought judgment module is used to judge whether the soil is dry according to the moisture content of the soil, judge in real time whether it is necessary to drive and transport water, and transmit the result to the water storage judgment module;

[0029] The water storage judgment module is used to judge whether the water collection tank needs water replenishment according to the water level data, and transmit the judgment result to the driving module;

[0030] The drive module is used to drive the start and stop of the solenoid valve and pump components.

[0031] Beneficial effects: The design of the control system has achieved a high degree of intelligence and automation. It can automatically determine whether irrigation is needed and the method of irrigation based on the data from the soil moisture sensor and the water level sensor, greatly reducing the frequency of manual intervention and improving work efficiency.

[0032] Furthermore, after receiving the data from the acquisition module, the drought judgment module first compares the soil moisture content with the soil moisture threshold. When the soil moisture content is less than the soil moisture threshold, a signal that water supply is required is transmitted to the water storage judgment module. Otherwise, a signal that water supply is not required is transmitted to the water storage judgment module.

[0033] Beneficial effects: By collecting soil moisture data in real time and comparing it with the soil moisture threshold, the drought judgment module can accurately identify whether the soil is in a drought state, which helps to avoid misjudgment and over-irrigation, thereby improving the utilization efficiency of water resources. Once the soil moisture content is lower than the threshold, the drought judgment module will immediately transmit a signal requiring water supply to the water storage judgment module, which can ensure that the irrigation system is quickly started when the soil is dry, meet the growth needs of crops, and avoid production reduction or losses caused by drought.

[0034] Furthermore, when the water storage judgment module receives a signal from the drought judgment module that water needs to be supplied, it compares the water level data with the height of the water storage chamber. When the water level is less than the height of the water storage chamber, the signal for starting the driving pump assembly and the solenoid valve is transmitted to the driving module, and the driving module starts the pump assembly and the solenoid valve. Conversely, when the water level is equal to the height of the water storage chamber, the signal for starting the solenoid valve is transmitted to the driving module, and the driving module starts the solenoid valve.

[0035] Beneficial effects: By comparing the real-time monitoring of water level data with the height of the water storage chamber, the water storage judgment module can accurately control when to start the pump assembly and the solenoid valve, thereby ensuring that the right amount of water resources are delivered to the drought-stricken areas when needed, which helps to avoid water waste and over-irrigation. When the water level is lower than the height of the water storage chamber, the pump assembly and the solenoid valve are started at the same time, which can quickly deliver the water in the water storage chamber to the drought-stricken areas. When the water level reaches the height of the water storage chamber, only the solenoid valve is started, and the natural pressure of the water is used for irrigation, which can not only meet the irrigation needs but also save energy.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] The following is further described in detail through specific implementation methods:

[0046] Embodiment 1:

[0047] As attached Figure 1 , Figure 2 , Figure 3 and Figure 4As shown: a device for restoring vegetation in abandoned mine land, comprising a vegetation blanket 1 for laying shrub seeds and nutrient soil, a plurality of fixing holes are opened on the vegetation blanket 1, and fixing piles 2 are detachably connected in the fixing holes. The vegetation blanket 1 comprises an upper mesh layer 101, a plant fiber layer 102, a seed layer 103 and a lower mesh layer 104 from top to bottom, and a gap 105 is provided between the plant fiber layer 102 and the seed layer 103. The operator first lays the vegetation blanket 1 on the abandoned mine land, and then drives a plurality of fixing piles 2 into the plurality of fixing holes for fixing. The design is conducive to the subsequent fixed piles 2 to use the fixed holes as the flow path for fertilizer nutrients for fertilization, and the porous design can make the fertilizer delivery more evenly dispersed; by laying the vegetation blanket 1, a base layer conducive to vegetation growth can be quickly covered on the abandoned mine land; the multi-layer design of the vegetation blanket 1 not only provides a stable support, but also ensures the uniform distribution of seeds and a good growth environment; the gap 105 between the plant fiber layer 102 and the seed layer 103 is conducive to the subsequent release of fertilizers, and directly acting on the seed layer 103 is conducive to the germination of seeds and the expansion of the root system.

[0048] A first water collecting component 6 for collecting and storing rainwater is placed on the vegetation blanket 1. The first water collecting component 6 includes a water collecting tank 601. The storage function of the water collecting tank 601 allows rainwater to accumulate, providing a stable water source for subsequent irrigation and vegetation growth. A first water collecting cover 602 is welded on the top of the water collecting tank 601. Through the collection function of the first water collecting cover 602, rainwater can be efficiently guided to the water collecting tank 601 to reduce the loss and waste of rainwater. The water collecting tank 601 is fused with a pump component, and the pump component includes a water pump. One end of the water pump is connected to the water collecting tank 601, and a plurality of fixed piles 2 are connected to the other end of the water pump. The water pump signal is connected to a control system. Through the connection between the water pump and the water collecting tank 601 and the plurality of fixed piles 2, rainwater can be dispersedly transported to the soil under the vegetation blanket 1 through the drive of the water pump, thereby realizing intelligent irrigation and improving irrigation efficiency. The control system is connected to the signal of the water pump, so that the irrigation process can be accurately controlled according to the soil moisture condition, reducing the probability of over-irrigation or insufficient irrigation, and achieving the effect of water-saving irrigation.

[0049] The fixed piles 2 include, from top to bottom, a functional tube 201 and a piercing tube 202 for piercing the soil for fixing. The functional tube 201 includes, from top to bottom, a water storage chamber 3, a fertilizer storage chamber 4 for storing fertilizers required for grass irrigating, and a water delivery chamber 5 for delivering water under the soil. The outer wall of the water storage chamber 3 is provided with a second water collecting component for collecting rainwater. The second water collecting component includes a second water collecting cover 7. The bottom end of the second water collecting cover 7 is welded to the outer wall of the water storage chamber 3. A plurality of water inlets are provided on the side wall of the water storage chamber 3. Through the design of the second water collecting cover 7 and the water inlet, rainwater can flow into the water inlet along the inner wall of the second water collecting cover 7, so that rainwater can be collected efficiently, which not only increases the area for rainwater collection, but also ensures that rainwater can smoothly enter the water storage chamber 3 for storage.

[0050] The water storage chamber 3 is connected to the fertilizer storage chamber 4 and the water delivery chamber 5 respectively. The setting of the fertilizer storage chamber 4 allows the fertilizer required for irrigating the grass to be stored, and through the connection with the water storage chamber 3 and the water delivery chamber 5, the intelligent supply of fertilizer is realized, which not only reduces the waste of fertilizer, but also improves the utilization rate of fertilizer. The mixed supply of fertilizer and water can nourish the vegetation more evenly and promote its healthy growth. The connection between the water storage chamber 3 and the fertilizer storage chamber 4 is fixedly connected with the electromagnetic valve 8 by bolts. The signal of the electromagnetic valve 8 is connected to the control system signal. The fertilizer storage chamber 4 is also connected to the gap 105 between the plant fiber layer 102 and the seed layer 103. Through the connection between the electromagnetic valve 8 and the control system, the fixed pile 2 can realize intelligent irrigation and fertilization. The opening and closing of the electromagnetic valve 8 is controlled accurately according to the time of irrigation and fertilization, and precise irrigation and fertilization are realized synchronously. The intelligent management method not only improves the accuracy of irrigation and fertilization, but also reduces the frequency of manual intervention and reduces maintenance costs. In the present invention, a water-soluble film is provided at the connection between the fertilizer storage chamber 4 and the gap 105. The design of the water-soluble film enables the fertilizer to be released only when it is fused with water, thereby achieving the effect of controlling the release timing of the fertilizer, reducing the waste of fertilizer, and reducing the risk of soil and water pollution caused by excessive fertilization. In addition, during the fertilization process, since the fertilizer in the fertilizer storage chamber 4 is placed in the chamber for a long time, there may be problems such as agglomeration and blockage that affect the release of the fertilizer. Under this design, the flow force of water is used to dilute the fertilizer in the fertilizer storage chamber 4, thereby reducing the risk of fertilizer agglomeration and enhancing the effect of subsequent fertilization.

[0051] A water level sensor 10 is welded to the inner wall of the water storage chamber 3. The water level sensor 10 can monitor the water level changes in the water storage chamber 3 in real time to ensure that the operator or the control system can understand the water storage status in time. The water level sensor 10 is connected to the control system signal. Through the connection with the control system, the water level sensor 10 can provide accurate water level data to control whether filling and replenishing water are needed. When the soil moisture content is low, the control system can determine whether it is necessary to start replenishing water based on the data of the water level sensor 10, so as to achieve water-saving irrigation according to the environmental characteristics of the abandoned mine site.

[0052] The bottom end of the piercing tube 202 is fixedly connected with a soil moisture sensor 9, which can monitor the moisture content in the soil in real time, provide accurate data support for the control system, help operators to understand the soil moisture in time, and provide a scientific basis for irrigation decisions. The soil moisture sensor 9 is connected to the control system signal. Through the connection with the control system, the soil moisture sensor 9 can achieve precise control of the irrigation system. When the soil moisture is lower than the preset threshold, the control system can automatically start the irrigation system to provide the right amount of moisture for the vegetation. The precise irrigation method helps to avoid the problem of over-irrigation or under-irrigation and improve the utilization efficiency of water resources.

[0053] The control system includes a preset module, a collection module, a drought judgment module, a water storage judgment module and a drive module.

[0054] The preset module records the operator entering different soil moisture thresholds according to different terrains.

[0055] The acquisition module collects the moisture content of the soil through the soil moisture sensor 9, and collects the water level data in the water storage chamber 3 through the water level sensor 10, and then transmits the data to the drought judgment module and the water storage judgment module respectively.

[0056] After receiving the data from the acquisition module, the drought judgment module first compares the soil moisture content with the soil moisture threshold. When the soil moisture content is less than the soil moisture threshold, a signal that water supply is required is transmitted to the water storage judgment module. Otherwise, a signal that water supply is not required is transmitted to the water storage judgment module.

[0057] When the water storage judgment module receives the signal that the drought judgment module needs to supply water, it compares the water level data with the height of the water storage chamber 3. When the water level is lower than the height of the water storage chamber 3, it transmits the signal to start the pump assembly and the solenoid valve 8 to the driving module, and the driving module starts the pump assembly and the solenoid valve 8. Conversely, when the water level is equal to the height of the water storage chamber 3, it transmits the signal to start the solenoid valve 8 to the driving module, and the driving module starts the solenoid valve 8.

[0058] The driving module receives the signal from the water storage judgment module to drive the solenoid valve 8 and the pump assembly to start and shut down.

[0059] Embodiment 2:

[0060] As attached Figure 2As shown, the difference from Example 1 is that a fixing block 11 is fixedly connected to the outside of the water storage chamber 3, and the fixing block 11 is a "concave"-shaped structure. The fixing block 11 of the "concave"-shaped structure can fit more effectively with the outside of the water storage chamber 3, and significantly improve the stability of the entire structure by increasing the contact area and the number of fixing points. This design helps to prevent the water storage chamber 3 from being deformed or damaged due to uneven force during long-term use. In addition, due to the terrain characteristics of the abandoned mine site, there may be rockfall on the slope that affects the fixing effect of the fixing pile 2. Improving the stability of the fixing pile 2 by the fixing block 11 is conducive to counteracting this special external force, so that the fixing pile 2 can stably exert its energy efficiency.

[0061] Embodiment 3:

[0062] As attached Figure 2 As shown, the difference from Example 2 is that a water pipe 12 is fixedly connected to the side wall of the water storage chamber 3, and the end of the water pipe 12 away from the water storage chamber 3 is connected to the water delivery chamber 5, and the connection point between the water pipe 12 and the water storage chamber 3 is located at the top of the side wall of the water storage chamber 3. On the one hand, since the connection point between the water pipe 12 and the water storage chamber 3 is located at the top of the side wall of the water storage chamber 3, when the water storage chamber 3 is full of water, the water will naturally flow to the water pipe 12 due to gravity, and then flow into the water delivery chamber 5. This design utilizes the natural pressure of water, and can achieve smooth transmission of water flow without adding additional power equipment such as water pumps. On the other hand, the position of the connection point between the water pipe 12 and the water storage chamber 3 is limited. In the process of collecting rainwater on rainy days, the excess rainwater collected can be irrigated into the soil through the water pipe 12, without excessively irrigating the seeds through the fertilizer storage chamber 4, and it can ensure that the water storage chamber 3 stores water for flowing into the fertilizer storage chamber 4.

[0063] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
