Therefore, they cannot be understood as limiting the scope of protection of this application.

[0034] The following is combined with Figure 1-Figure 3 The index data acquisition device used in the ecological restoration of tailings in the tailings pond of the present application is further described in detail.

[0035] The index data acquisition device used in the ecological restoration of tailings in tailings ponds of the present application may include an outer shell 1, an inner shell 2, a filter layer 13, an outer shell cover 7, a sensor probe 11, a signal processing device 8, a telescopic rod 4 and a support frame 12.

[0036] Specifically, the top of the outer shell 1 has an opening, and a plurality of through holes are evenly distributed on the shell; similarly, the top of the inner shell 2 has an opening, and a plurality of through holes are evenly distributed on the shell. The outline size of the inner shell 2 is smaller than the outline size of the outer shell 1, and it is embedded in the outer shell 1, so that a cavity 3 surrounding the inner shell 2 is formed between the outer wall of the inner shell 2 and the inner wall of the outer shell 1.

[0037] It should be noted that the outer shell 1 and the inner shell 2 can adopt various shapes as needed, such as cylindrical, rectangular, conical, etc. In this embodiment, Figure 1-3 As shown, the outer shell 1 and the inner shell 2 are preferably both cylindrical in shape, and the outer shell 1 adopts a porous rigid structure with a pore size of 2-5 mm to facilitate subsequent insertion into the tailings and ensure that the gap water in the tailings can smoothly enter the interior of the shell, while protecting the inner shell 2. The inner shell 2 adopts a porous rigid membrane with a pore size of 0.5-1 mm to further filter particulate impurities in the gap water in the tailings, thereby ensuring the measurement stability and accuracy of the subsequent sensor probe.

[0038] The filter layer 13 is filled and set in the cavity 3. Similarly, the filter layer 13 can contain a variety of suitable filter materials. In this embodiment, it is preferred that the filter layer 13 contains zeolite and quartz sand particles. Zeolite and quartz sand can not only filter out some impurities, but also balance the water quality, which contributes to more accurate detection results.

[0039] The outer shell cover 7 is configured to be able to be installed at the opening of the integral structure formed by the outer shell 1 and the inner shell 2 through a sealing cover at the top. Similarly, the shape of the outer shell cover 7 can be determined according to the shapes of the outer shell 1 and the inner shell 2. When the outer shell 1 and the inner shell 2 are cylindrical, the outer shell cover 7 is preferably a trapezoidal frustum structure, and is installed at the opening of the integral structure formed by the outer shell 1 and the inner shell 2 through a sealing cover at its bottom end. In addition, the outer shell cover 7 has an inner cavity.

[0040] In addition, in order to further ensure the sealing between the outer shell cover 7 and the outer shell 1 and the inner shell 2, it is preferably provided with a circle of protrusions 9 at the top opening of the outer shell 1, and a sealing ring is provided on the protrusion 9. In addition, a groove adapted to the protrusion 9 is provided on the bottom surface of the outer shell cover 7, and the sealing performance is increased through the cooperation of the two.

[0041] Multiple sensing probes 11 are evenly distributed within the inner cavity of the inner shell 2 and are used to measure, in real time, the physical and chemical parameters of the interstitial water in the tailings entering the inner cavity. These parameters include water level, redox potential, total ion concentration, pH, dissolved oxygen, total nitrogen, total phosphorus, and total organic carbon. Furthermore, the sensing probes are preferably constructed of corrosion-resistant and oxidation-resistant materials to adapt to the complex tailings environment and extend their service life.

[0042] The signal processing device 8 is arranged on the outer shell cover 7 and is connected to the multiple sensor probes 11 through signal lines (i.e., data transmission lines) that penetrate the outer shell cover 7 and enter the inner cavity of the inner shell 2, so that it can receive and process the physical and chemical index data collected by each probe. When the outer shell cover 7 adopts the above-mentioned trapezoidal frustum structure, the signal processing device 8 is preferably fixedly arranged in the inner cavity of the outer shell cover 7; it should also be noted that the signal processing device 8 preferably adopts a multi-source data processor that can process data from multiple sensor probes at the same time, and has the characteristics of anti-interference and high data stability. In addition, the processed data can be uploaded to the terminal system by wireless or wired means for technicians to monitor and adjust the repair process in real time.

[0043] There are at least two telescopic rods 4, which are symmetrically and parallel to each other on the outside of the outer shell 1. The telescopic direction of each telescopic rod 4 is consistent with the opening direction of the outer shell 1, and one end of the telescopic rod 4 is fixedly connected to the outer wall of the outer shell 1 through a fixing member 14.

[0044] Among them, the telescopic rod 4 is convenient for vertically inserting the entire device into the tailings on the one hand, and can play the role of fixing the outer shell cover 7 on the other hand. Therefore, the telescopic rod 4 can adopt a variety of telescopic devices, such as threaded telescopic rods, hydraulic rods, etc., and its control method can be manually controlled by the operator; in addition, the above-mentioned fixing member 14 can also be a variety of structures, such as a fixing rod, a fixing plate. In this embodiment, in order to facilitate the installation of the telescopic rods 4 (especially when there are multiple numbers), the fixing member 14 is preferably a circular plate, and is coaxially fixedly sleeved on the outer wall surface of the outer shell 1, wherein the bottom ends of at least two telescopic rods 4 are fixedly connected to the top surface of the circular plate.

[0045] The support frame 12 is located at the top opening of the outer shell 1 and is fixedly connected to the other end of each telescopic rod 4 and the top of the outer shell cover 7. On the one hand, the support frame 12 can ensure the consistency of the installation of multiple telescopic rods 4, and on the other hand, it cooperates with the telescopic rod 4 to ensure the sealing stability of the outer shell cover 7. Furthermore, it can also be connected through external fixing equipment of the support frame 12 (such as the fixing frame and fixing point originally set at the tailings pond, etc.), so as to ensure the stability of the device when collecting data and prevent displacement from affecting the accuracy of the data. Similarly, the support frame 12 can be a variety of suitable shapes. In the embodiment itself, the support frame 12 is preferably disc-shaped and arranged parallel to and coaxially with the fixing member 14. In addition, the support frame 12 is fixedly connected to the other end of each telescopic rod 4 through its outer circumference.

[0046] Furthermore, the index data acquisition device for the ecological restoration of tailings in tailings ponds of the present application can also include a central axis body 10, one end of which passes through the bottom surface of the outer shell cover body 7 and is connected to the signal processing device 8 in the inner cavity, and the other end extends into the inner cavity of the inner shell 2 along the central axis direction of the inner shell 2, wherein at least a part of the multiple sensor probes 11 arranged in the inner cavity of the inner shell 2 is fixed on the central axis body 10 and distributed on both sides of the central axis body 10 in a tree-like symmetrical manner, and another part of the multiple sensor probes 11 is evenly distributed on the bottom plate of the inner shell 2. Such an arrangement of multiple sensor probes 11 can improve the coverage and accuracy of data acquisition.

[0047] Furthermore, to facilitate subsequent maintenance of the device, the index data collection device for tailings ecological restoration of tailings ponds of the present application may also include multiple aeration inlet pipes 6 and multiple drainage pipes 5. The multiple aeration inlet pipes 6 penetrate the outer shell 1 on one side of the outer shell 1 and are inserted into the filter layer 13. The multiple aeration inlet pipes 6 are evenly distributed along the axial direction of the outer shell 1. The multiple drainage pipes 5 penetrate the outer shell 1 on the other side opposite the outer shell 1 and are inserted into the filter layer 13. Similarly, the multiple drainage pipes 5 are evenly distributed along the axial direction of the outer shell 1. The provision of the aeration inlet pipe 6 and the multiple drainage pipes 5 on the outer shell facilitates regular flushing of the interior of the device to ensure the sensitivity of the probe and the long-term stability of the device. The design of the check valve prevents water from flowing back, thereby protecting the internal structure of the device.

[0048] The installation and operation process of the index data acquisition device for tailings pond tailings ecological restoration in this application is as follows:

[0049] First, fix the support frame 12 to the external fixing equipment (such as the fixing frame and fixing point originally set up at the tailings pond), and then operate the hydraulic rod 4 to insert the device vertically into the tailings. When the outer shell 1 is basically inserted into the tailings, release the connection between the support frame 12 and the external fixing equipment, and operate the hydraulic rod 4 to drive the outer shell cover 7 sealing cover to be set at the opening of the overall structure formed by the outer shell 1 and the inner shell 2.

[0050] When the device is inserted vertically into the tailings, interstitial water in the tailings gradually passes through the outer shell 1, filter layer 13, and inner shell 2, gradually entering the interior of the device (in the inner cavity of inner shell 2) and coming into contact with the sensor probe 11 therein. Sensor probe 11 collects real-time data such as water level, redox potential, and total ion concentration. Signal processing device 8 receives data from sensor probe 11 and analyzes and transmits it through a data processor. The data is uploaded to the terminal in real time for technical personnel to review, helping them adjust the restoration process and materials according to the needs of ecological restoration.

[0051] In summary, the index data acquisition device for the ecological restoration of tailings ponds in the present application is particularly suitable for use in the ecological restoration monitoring of tailings ponds in mining areas. It can meet the needs of multi-parameter data acquisition in harsh environments, provide physical and chemical indicators of interstitial water in tailings, and help technicians understand the ecological restoration status of tailings ponds in real time, and adjust the restoration strategy in time to ensure that the growth environment of plants and microorganisms is effectively improved.

[0052] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
