Description

Technical Field

[0001] The present invention relates to the technical field of mine ecological restoration, and specifically to a detection device for mine ecological restoration. Background Art

[0002] Mine ecological restoration refers to the treatment of geological disaster hazards, environmental pollution and other problems through scientific and systematic restoration projects, and the adoption of ecological nurturing measures to gradually restore the environmental functions of closed mines and achieve sustainable and healthy development of their own ecological environment. Mine ecological restoration is a complex and long-term process aimed at restoring the ecosystem damaged by mining activities. As an important part of the ecosystem, the restoration and monitoring of soil quality are the key links in mine ecological restoration. However, the special environment and complex ecological processes in mines pose many challenges to the real-time monitoring of soil through detection devices.

[0003] Before mine ecological restoration, it is necessary to monitor the soil environment of the mine through a detection device to understand its pollution degree, ecological damage situation, etc., so as to provide a basis for formulating a scientific and reasonable restoration plan. During and after the restoration process, continuous monitoring of the mine soil environment can intuitively understand whether the restoration measures are effective and whether the expected ecological restoration goals have been achieved, so as to adjust the restoration strategy in a timely manner. However, most of the existing detection devices are suitable for sampling before restoration. When the sensor probe samples, no protection measures are set. In the complex mine environment, the sensor probe is in long-term contact with the soil and is easily corroded and damaged by acidic substances, salts and oxidation substances in the mine soil, affecting the accuracy of the sensor probe and making it difficult to maintain in the soil for a long time, unable to collect the information of the soil during restoration in real time. And every time soil information needs to be collected, the detection device needs to be redeployed, which greatly reduces the efficiency of soil information collection. Summary of the Invention

[0004] The purpose of the present invention is to provide a detection device for mine ecological restoration to solve the above problems.

[0005] The technical solution of the present invention is as follows:

[0006] A mine ecological restoration detection device, comprising: a test rod, which is a hollow rod, with threads opened along its axial direction on the circumferential side of the test rod, and channels communicating with the inside of the test rod are opened between adjacent threads. One end of the test rod is provided with a drill bit, and the extending direction of the threads faces the drill bit; a control component housing, connected to the other end of the test rod and communicating with the inside of the test rod. A motor and a controller are arranged in the control component housing. The controller is connected to the motor, and the controller is connected to the remote end for communication; a central shaft, located on the central axis of the test rod, with one end connected to the output shaft of the motor. An arc-shaped piece is arranged on the circumferential side of the central shaft. The arc-shaped piece is a flexible metal thin sheet. One end of the arc-shaped piece is fixed on the circumferential side of the central shaft, and a sensor mounting groove is opened at the other end; an inner sleeve, sleeved inside the test rod. An arc-shaped groove penetrating the pipe wall is opened along the thickness direction of the pipe wall of the inner sleeve. The arc-shaped groove is aligned and communicated with the channel, and the radian of the channel and the arc-shaped groove match. The other end of the arc-shaped piece slides in the arc-shaped groove and expands and contracts in the channel through the rotation of the central shaft. When in use, the test rod can be inserted into the soil and kept inside the soil. When detection is required, the controller controls the motor to rotate the central shaft. Through the above principle, the end of the arc-shaped piece installed with the sensor extends out of the channel and enters the soil. The measured soil data is recorded by the controller and transmitted to the terminal device. After testing the soil information, the motor is controlled to rotate the central shaft in the reverse direction so that the arc-shaped piece retracts back into the arc-shaped groove to prevent the corrosion and damage of the sensor probe by harmful substances in the soil, ensure the test accuracy of the sensor probe, and moreover, can timely control the arc-shaped piece to extend into the soil to complete the collection when the soil information needs to be tested, can realize the real-time monitoring of the soil information during restoration, save the time for arranging sampling equipment for each soil information collection, and improve the efficiency of obtaining soil information.

[0007] Further, multiple grooves are opened at the protruding parts of the threads. During the process of screwing the test rod into the soil, the soil is loosened so that the arc-shaped piece can be inserted into the soil more smoothly and the damage to the sensor by sand and gravel particles in the dense soil can be avoided.

[0008] Further, a plurality of arc-shaped pieces are arranged on the circumferential side of the central shaft, and the plurality of arc-shaped pieces are arranged in a circular array centered on the central shaft. A plurality of arc-shaped grooves are opened at the positions corresponding to the arc-shaped pieces on the pipe wall of the inner sleeve, and a plurality of channels are opened at the positions corresponding to the arc-shaped grooves on the test rod. Through the arrangement of the plurality of arc-shaped pieces, the plurality of arc-shaped grooves and the channels, sensor groups can be arranged on the plurality of arc-shaped pieces to obtain soil quality information in a larger range, and then the collected multiple pieces of information are compared and analyzed to improve the accuracy of the soil quality assessment here.

[0009] Furthermore, a plurality of sensor mounting grooves are formed in each of the arc-shaped pieces, and the plurality of sensor mounting grooves are arranged in a rectangular array. Through the uniformly arranged sensor combination, the plurality of sensors can be reasonably arranged and integrated on the arc-shaped pieces to more accurately collect different soil information at the soil position where the arc-shaped pieces are located.

[0010] Furthermore, a sensor wire groove is formed in the arc-shaped piece, a wire pipe is inlaid along the axial direction of the central shaft, one end of the sensor wire groove communicates with the sensor mounting groove, and the other end communicates with the wire pipe. The connecting wire of the sensor is connected to the controller through the wire pipe. The sensor wire groove and the wire pipe can make the connecting wire of the sensor be more reasonably arranged in the device, playing a protective role for the connecting wire, so as to ensure the normal operation of the sensor.

[0011] Furthermore, a gasket is provided on the side channel wall of the channel in contact with the arc-shaped piece where the sensor mounting groove is formed. Through the gasket, a certain distance can be formed between the arc-shaped piece and the channel wall of the channel, so as to prevent the sensor in the sensor mounting groove from rubbing against the inner wall of the channel and causing damage to the sensor probe.

[0012] Furthermore, a plurality of channels are formed in the test rod in its length direction, and the inner sleeve can be arranged at the channel positions at different depths in the test tube to obtain the soil information at this position.

[0013] Furthermore, in order to facilitate the adjustment of the position of the inner sleeve and reduce the difficulty of adjusting the position of the inner sleeve, a fixed frame is fixed on the periphery of the motor, the fixed frame is slidably connected to the inner wall of the control component housing, and the fixed frame slides along the height direction of the control component housing. The inner sleeve and the fixed frame are connected through a connecting rod, so that the inner sleeve can slide in the inner cavity of the test rod through the movement of the fixed frame. By controlling the position of the fixed frame, the position of the inner sleeve in the test rod can be controlled.

[0014] Furthermore, it further includes: a lifting rod, one end of which is connected to the fixed frame and the other end penetrates through the top of the control component housing, and a horizontal rod is connected to the side surface of the other end of the lifting rod; a scale rod, one end of which is connected to the horizontal rod and the other end penetrates into the control component housing. Scales are engraved on the scale rod, and the distance between every two adjacent scale lines is equal to the distance between two adjacent channels. A hole is provided at each scale line position on the scale rod; a pin can be inserted into the hole, enabling the staff to accurately obtain the displacement distance of the inner sleeve according to the scale lines on the scale rod, so as to determine the position of the channel where the inner sleeve is located.

[0015] Further, the length of the connecting rod can be replaced. The two ends of the connecting rod are respectively threadedly connected to the fixed frame and the inner sleeve, so that the inner sleeve can first determine a displacement range, and within this range, the lifting rod is used to adjust the moving position of the inner sleeve within this range.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. The test rod of the present invention can be vertically inserted into the repaired soil in the mining area and remain inside the soil. During the soil repair process, the soil information here can be obtained in real time. When detection is required, the controller controls the motor to rotate the central shaft, so that the end of the arc-shaped piece equipped with the sensor extends out of the channel and enters the soil. The measured soil data is recorded by the controller and transmitted to the terminal device. After testing the soil information, the motor is controlled to rotate the central shaft in the reverse direction so that the arc-shaped piece retracts back into the arc-shaped groove again, in order to prevent the corrosion and damage of the sensor probe by harmful substances in the soil, ensure the test accuracy of the sensor probe, avoid the time cost caused by the repair of the detection device due to the damage of the sensor probe, and moreover, through the cooperation of the controller, the motor and the central shaft, when the soil information needs to be tested, the arc-shaped piece is timely controlled to extend into the soil to complete the collection, realizing the real-time monitoring of the soil information during the repair, saving the time for arranging sampling equipment for each soil information collection, and improving the efficiency of obtaining soil information.

[0027] Embodiment

[0028] As Figure 1 shown, a mine ecological restoration detection device includes: a test rod 1, a control component housing 2, a central shaft 3, and an inner sleeve 4. The test rod 1 is a hollow rod. Threads 11 are provided on the circumferential side of the test rod 1 along its axial direction, and channels 12 communicating with the inside of the test rod 1 are provided between adjacent threads 11. A drill bit is provided at one end of the test rod 1, and the extending direction of the threads 11 faces the drill bit. The test rod 1 is vertically inserted into the restored soil of the mine area, and then the test rod 1 is rotated. The test rod 1 is screwed into the soil and fixed by the drill bit and the threads 11; the control component housing 2 is connected to the other end of the test rod 1 and communicates with the inside of the test rod 1, as Figure 2As shown in the figure, a motor 21 and a controller are provided inside the control component housing 2. The controller is connected to the motor 21 and is connected and communicates with the remote end. It should be noted that the motor 21 is a servo motor, which is equipped with a control module that can be controlled by the controller and control the number of rotations of the output shaft of the motor 21. The controller can be remotely controlled through the terminal device at the remote end, and the sensor is connected to the controller. The controller is used to save and send the information collected by the sensor to the terminal device; as Figure 3 As shown in the figure, the central shaft 3 is located on the central axis of the test rod 1. One end of the central shaft 3 is connected to the output shaft of the motor 21. An arc-shaped piece 5 is provided on the periphery of the central shaft 3. The arc-shaped piece 5 is a flexible metal thin sheet. One end of the arc-shaped piece 5 is fixed on the periphery of the central shaft 3, and a sensor mounting groove 51 is opened at the other end. The sensor is mounted on the arc-shaped piece 5 through the sensor mounting groove 51. The type of the sensor can be configured according to local detection requirements; the inner sleeve 4 is sleeved inside the test rod 1. An arc-shaped groove 41 penetrating the pipe wall is opened in the inner sleeve 4 along the thickness direction of its pipe wall. The arc-shaped groove 41 is aligned and communicated with the channel 12, and the radian of the channel 12 and the arc-shaped groove 41 matches. The other end of the arc-shaped piece 5 slides in the arc-shaped groove 41. And because the arc-shaped piece 5 has elasticity, by rotating the central shaft 3, the other end of the arc-shaped piece 5 slides from the arc-shaped groove 41 into the channel 12 and can extend from the channel 12 into the soil to obtain the information of the soil at this depth. When in use, the test rod 1 can be inserted into the soil and the test rod 1 can be kept inside the soil. When detection is needed, the controller controls the motor 21 to rotate the central shaft 3. Through the above principle, the end of the arc-shaped piece 5 equipped with the sensor extends out of the channel 12 and enters the soil. The measured soil data is recorded by the controller and transmitted to the terminal device. After testing the soil information, control the motor 21 to rotate the central shaft 3 in the reverse direction so that the arc-shaped piece 5 retracts into the arc-shaped groove 41 again to prevent the harmful substances in the soil from corroding and damaging the sensor probe, ensure the test accuracy of the sensor probe, and moreover, can timely control the arc-shaped piece 5 to extend into the soil to complete the collection when soil information needs to be tested, can realize real-time monitoring of the soil information during repair, save the time for arranging sampling equipment for each collection of soil information, and improve the efficiency of obtaining soil information.

[0029] As Figure 1 As shown in the figure, a plurality of grooves 13 are opened at the convex portions of the thread 11. Through the plurality of grooves 13, the soil can be loosened during the process of screwing the test rod 1 into the soil, so that the arc-shaped piece 5 can be inserted into the soil more smoothly, and the damage of the sand and gravel particles in the dense soil to the sensor can be avoided.

[0030] As Figure 3As shown in the figure, a plurality of arc-shaped pieces 5 are provided on the circumferential side of the central axis 3. The plurality of arc-shaped pieces 5 are arranged in a circular array with the central axis 3 as the center. A plurality of arc-shaped grooves 41 are opened on the tube wall of the inner sleeve 4 at positions corresponding to the arc-shaped pieces 5. A plurality of channels 12 are opened on the test rod 1 at positions corresponding to the arc-shaped grooves 41. Through the arrangement of the plurality of arc-shaped pieces 5, the plurality of arc-shaped grooves and the channels, sensor groups can be arranged on each of the plurality of arc-shaped pieces 5 to obtain soil quality information in a larger range, so as to compare and analyze the plurality of collected information and improve the accuracy of the soil quality assessment here.

[0031] In some embodiments, a plurality of sensor mounting grooves 51 are opened on each arc-shaped piece 5, and the plurality of sensor mounting grooves 51 are arranged in a rectangular array. Through the evenly arranged sensor combination, the plurality of sensors can be reasonably arranged and integrated on the arc-shaped piece 5 to more accurately collect different information of the soil at the soil position where the arc-shaped piece 5 is located.

[0032] As Figure 4 and Figure 3 shown in the figure, a sensor wire groove 52 is opened on the arc-shaped piece 5, and a wire pipe 31 is inlaid along the axial direction of the central axis 3. One end of the sensor wire groove 52 is communicated with the sensor mounting groove 51, and the other end is communicated with the wire pipe 31. The connecting wire of the sensor is connected to the controller through the wire pipe 31. Through the sensor wire groove 52 and the wire pipe 31, the connecting wire of the sensor can be more reasonably arranged in the device, playing a protective role for the connecting wire, so as to ensure the normal operation of the sensor.

[0033] As Figure 4 shown in the figure, a gasket 43 is provided on the channel wall of the channel 12 in contact with the sensor mounting groove 51 opened on the arc-shaped piece 5. Through the gasket 43, a certain distance can be provided between the arc-shaped piece 5 and the channel wall of the channel 12, so as to prevent the sensor in the sensor mounting groove 51 from rubbing against the inner wall of the channel 12, resulting in damage to the sensor probe.

[0034] In some embodiments, in order to be able to collect soil information at different depth positions, as Figure 1 shown in the figure, a plurality of channels 12 are opened in the test rod 1 in its length direction, and the inner sleeve 4 can be arranged at different depth channel 12 positions in the test tube 1 to obtain the soil information at this position.

[0035] In some embodiments, in order to facilitate the adjustment of the position of the inner sleeve 4 and reduce the difficulty of adjusting the position of the inner sleeve 4, as Figure 2As shown, a fixed frame 22 is fixed to the circumferential side of the motor 21. The fixed frame 22 is slidably connected to the inner wall of the control component housing 2, and the fixed frame 22 slides along the height direction of the control component housing 2. The inner sleeve 4 and the fixed frame 22 are connected by a connecting rod 42, so that the inner sleeve 4 can slide in the inner cavity of the test rod 1 through the movement of the fixed frame 22. By controlling the position of the fixed frame 22, the position of the inner sleeve 4 in the test rod 1 can be controlled.

[0036] To improve the accuracy of adjusting the position of the inner sleeve 4, as Figure 2 shown in the detection device, it further includes: a lifting rod 23, a scale rod 24 and a pin 25. One end of the lifting rod 23 is connected to the fixed frame 22, and the other end passes through the top of the control component housing 2. A horizontal rod is connected to the side of the other end of the lifting rod 23; one end of the scale rod 24 is vertically connected to the horizontal rod, and the other end penetrates into the control component housing 2. The scale rod 24 is engraved with scales, and the distance between every two adjacent scale lines is equal to the distance between two adjacent channels 12. A hole is provided at each position of each scale line on the scale rod 24; the pin 25 can be inserted into the hole. Moving the lifting rod 23 can move the fixed frame 22. Through the action of the connecting rod 42, the inner sleeve 4 is driven, and according to the scale lines on the scale rod 24, the displacement distance of the inner sleeve 4 can be accurately obtained, so as to determine the position of the channel 12 where the inner sleeve 4 is located.

[0037] In some embodiments, the length of the connecting rod 42 can be replaced. The two ends of the connecting rod 42 are respectively threadedly connected to the fixed frame 22 and the inner sleeve 4, so that the inner sleeve 4 can first determine a displacement range, and within this range, the position of the inner sleeve 4 within this range can be adjusted by the lifting rod 23.
