Description

Technical Field

[0001] The invention relates to the technical field of environmental pollution sampling, and in particular to an environmental pollution sampling detection device. Background Art

[0002] Environmental pollution refers to the phenomenon that human activities or natural factors lead to the decline of environmental quality, destruction of ecosystems and waste of resources, which in turn have a negative impact on organisms, plants, air and water sources. Environmental pollution not only affects the ecological balance, but also harms human health. Soil pollution is one type of environmental pollution. Soil pollution mainly refers to the entry of harmful substances (such as heavy metals, pesticides and industrial waste) into the soil, which leads to the decline of soil quality and affects the growth of plants and the safety of human food. Therefore, it is necessary to sample and test the soil even if the source of pollution is found.

[0003] The traditional soil sampling method is usually to insert the sampling tube directly into the soil for sampling. However, the data obtained by this method covers a wide range and it is difficult to accurately detect soils at different depths. If detailed analysis of soils at different depths is required, the sampling personnel usually need to repeat the operation multiple times to extract soil samples layer by layer. This operation is not only time-consuming and labor-intensive, but also the depth and accuracy of each sampling may vary, thus affecting the accuracy of the results. Although some equipment can realize the function of multiple sampling, the sampling interval is fixed and cannot be flexibly adjusted, resulting in some key soil layers not being fully representatively sampled, and the sampling data is unbalanced, which in turn affects the location of soil pollution sources. In view of this, the present invention provides an environmental pollution sampling and detection device to at least solve one of the above-mentioned technical problems. Summary of the invention

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0027] An environmental pollution sampling and detection device, such as Figure 1-Figure 9As shown, it includes a rotating cylinder 11, which is driven by a driving device to achieve rotation and lifting. An auger blade 12 is fixedly connected to the outer wall of the rotating cylinder 11 and a drill bit 13 is installed at the bottom. Specifically, the driving device includes a bottom plate 61, and a moving wheel 62 is installed on the bottom surface of the bottom plate 61. The moving wheel 62 can enable the equipment to move smoothly, which is convenient for the equipment to move in different working scenes. A mounting plate 63 is fixedly connected to the top surface of the bottom plate 61, and a hydraulic telescopic rod 64 is installed on the mounting plate 63. A fixed plate 65 is fixedly connected to the telescopic rod of the hydraulic telescopic rod 64. A first motor 66 is installed on the bottom surface of the fixed plate 65, and a mounting seat 67 is fixedly connected to the output shaft of the first motor 66. The bottom surface of the mounting seat 67 is fixedly connected to the rotating cylinder 11. Furthermore, four third threaded rods 71 ​​are symmetrically threaded on the bottom plate 61. The four third threaded rods 71 ​​are arranged at four corners of the bottom plate 61. The third threaded rod 71 passes through the bottom plate 61, and the lower end of the third threaded rod 71 is fixedly connected to an anchor 7 2. A rotating handle 73 is fixedly connected to the top of the third threaded rod 71. It can be seen that the device is moved to the soil sampling location by the moving wheel 62, and then the operator rotates the third threaded rod 71, so that the third threaded rod 71 rotates and descends, and the third threaded rod 71 drives the anchor 72 to rotate and descend, so that the anchor 72 can penetrate into the ground, thereby stabilizing the device to prevent the device from sliding or becoming unstable. The hydraulic telescopic rod 64 and the first motor 66 are started, and the telescopic rod of the hydraulic telescopic rod 64 drives the rotating cylinder 11 to move downward, and the output shaft of the first motor 66 drives the rotating cylinder 11 to rotate, and then the rotating cylinder 11 drives the auger rod blades 12 and the drill bit 13 to move downward and rotate at the same time, so that the rotating cylinder 11 can penetrate into the soil through the drill bit 13, and the auger rod blades 12 can assist the drill bit 13 to bring out the soil, so that the drill bit 13 can penetrate the soil more easily, prevent soil from accumulating around the drill bit 13, speed up the drilling speed, and improve the sampling efficiency.

[0028] A notch groove 121 is provided on the auger stem blade 12, and the provision of the notch groove 121 does not affect the normal operation of the auger stem blade 12. The interior of the rotating cylinder 11 is hollow, and a sampling groove group matching the notch groove 121 is provided on the side wall; a sampler group, the sampler group includes a first sampler 21, a second sampler 22 and a third sampler 23, the sampler group is arranged in the rotating cylinder 11 at the sampling groove group, wherein the third sampler 23 is arranged in the middle of the rotating cylinder 11, and the first sampler 21 and the second sampler 22 are both provided with two with the third sampler 23 as the symmetric center, that is, in order from top to bottom, the first sampler 21, the second sampler 22, the third sampler 23, the second sampler 22 and the first sampler 21 are arranged in this order. , the first sampler 21 and the second sampler 22 are distanced relative to the third sampler 23 by adjusting the assembly, and the distance between the second sampler 22 and the third sampler 23 and the distance between the first sampler 21 and the corresponding second sampler 22 are always kept equal, "corresponding" refers to the second sampler 22 located on the same side as the first sampler 21 with the third sampler 23 as the center, for example, the distance between the first sampler 21 and the second sampler 22 located on the upper side with the third sampler 23 as the center, so that the distance between the second sampler 22 and the third sampler 23 and the distance between the first sampler 21 and the corresponding second sampler 22 are always kept equal, which can ensure that the collection positions of the samples are evenly distributed in the longitudinal direction, which helps to ensure that the sample collection positions are uniformly distributed in the longitudinal direction, and helps to ensure that the sample collection positions are uniformly distributed in the longitudinal direction, and the sample collection positions are uniformly distributed in the longitudinal direction, which helps to ensure that the sample collection positions are uniformly distributed in the longitudinal direction, and ... The soil samples obtained at different depths are representative, thereby improving the accuracy of environmental pollution sampling. At the same time, the distance between the first sampler 21 and the second sampler 22 relative to the third sampler 23 can be adjusted through the adjustment component, so as to change the sampling interval, so as to meet the sampling requirements under different soil types or environments and improve the adaptability of the equipment. The adjustment component includes a threaded rod mechanism for driving the first sampler 21 and the second sampler 22 to move, and a second motor 31 for controlling the rotation of the threaded rod mechanism. The second motor 31 is installed on the mounting seat 67. The second motor 31 is provided with an encoder, which can record the number of rotations of the threaded rod mechanism, so as to obtain the sampling interval. The pushing component is arranged inside the rotating cylinder 11, and the pushing component is used to drive the sampler assembly Extending or retracting into the sampling slot group, the shielding component is arranged at the opening of the sampling slot group, and is used to close or open the channel of the sampling slot group. When the sampler group is extended, the sampling slot group is opened, and the rest of the time it is in a closed state. The main purpose is to prevent soil from entering the interior of the rotating cylinder 11 from the sampling slot group. It can be seen that when the rotating cylinder 11 reaches the sampling position, it stops rotating. At this time, according to the properties of the soil, the distance between the first sampler 21 and the second sampler 22 relative to the third sampler 23 is adjusted by the adjustment component, and then the sampling slot group is opened by the shielding component, and the first sampler 21, the second sampler 22 and the third sampler 23 are pushed out by the pushing component, so that the first sampler 21, the second sampler 22 and the third sampler 23 can collect soil.Then, the first sampler 21, the second sampler 22 and the third sampler 23 are retracted by pushing the assembly, the sampling slot group is closed by the shielding assembly, and then the rotating cylinder 11 is driven upward by the hydraulic telescopic rod 64 to complete the soil sampling operation. The device samples the soil from the side, which helps to reduce the disturbance of the soil layer, maintain the natural structure of the soil, and thus improve the representativeness and accuracy of the sample.

[0029] Specifically, the third sampler 23 includes a card plate 241 and a sampling barrel 242, the card plate 241 is slidably connected to the sampling barrel 242, the opening of the sampling barrel 242 faces the sampling slot group and a special structure (such as a spiral edge, a blade or a toothed edge) is adopted at the opening. This structure is a prior art or the same as the prior art, and the purpose is to enable the soil to be collected in the sampling barrel 242, so it is not shown in the figure. A spiral groove 2421 is arranged on the outer wall of the sampling barrel 242, and a card ball 243 matching the spiral groove 2421 is arranged on the card plate 241. Telescopic plates are arranged at the upper and lower ends of the card plate 241. The sampler 21 and the second sampler 22 are configured the same as the third sampler 23, that is, the first sampler 21, the second sampler 22 and the third sampler 23 adopt the same structure, so that when the pushing component pushes the first sampler 21, the second sampler 22 and the third sampler 23, the pushing component pushes all the sampling tubes 242 to extend out of the sampling slot group, and when the sampling tube 242 is extended, the sampling tube 242 can realize self-rotation through the cooperation of the spiral groove 2421 and the card ball 243, and then cooperate with the structure of the opening of the sampling tube 242, so that the sampling tube 242 can smoothly cut into the soil for sampling.

[0030] Specifically, the threaded rod mechanism includes a rotating rod 301 and a first threaded rod 302 and a second threaded rod 303 fixedly connected to the rotating rod 301. The rotating rod 301 is rotatably connected to the mounting seat 67. The first threaded rod 302 and the second threaded rod 303 are respectively threadedly connected to the clamping plate 241 of the first sampler 21 and the clamping plate 241 of the second sampler 22. The clamping plate 241 of the third sampler 23 is rotatably connected to the rotating rod 301. In this way, when the second motor 31 drives the threaded rod mechanism to rotate, only the positions of the first sampler 21 and the second sampler 22 are adjusted. The position of the third sampler 23 will not be adjusted, so that it is convenient to understand the sampling depth and calculate the sampling interval. The pitch of the first threaded rod 302 and the second threaded rod 303 are set proportionally, so that when the number of turns of the rotating rod 301 is the same, the distance of the first sampler 21 is twice that of the second sampler 22. It should be understood that the thread directions of the first threaded rod 302 and the second threaded rod 303 located on the upper side with the third sampler 23 as the center are different from those of the first threaded rod 302 and the second threaded rod 303 located on the lower side, that is, the first threaded rod 302 and the second threaded rod 303 located on the upper side are different from those of the first threaded rod 302 and the second threaded rod 303 located on the lower side. The sampler 21 and the second sampler 22 move in different directions from the first sampler 21 and the second sampler 22 located at the lower side. At the same time, since the first sampler 21 is arranged at both ends, and the distance between the second sampler 22 and the third sampler 23 and the distance between the first sampler 21 and the corresponding second sampler 22 are required to be always equal, the distance between the first sampler 21 and the second sampler 22 needs to be twice that of the second sampler 22. Therefore, the pitch ratio of the first threaded rod 302 and the second threaded rod 303 is 2:1. It can be seen that when the second motor 31 is started, The output shaft of the second motor 31 drives the rotating rod 301 to rotate, and the rotating rod 301 drives the first threaded rod 302 and the second threaded rod 303 to rotate, and then through the threaded connection, the clamping plate 241 of the first sampler 21 and the clamping plate 241 of the second sampler 22 are moved, so that the sampling interval can be adjusted. Since the second motor 31 can record the number of rotations of the threaded rod mechanism, the sampling interval can be obtained, which makes it convenient for the operator to monitor and record each operation in real time, providing the necessary basis for subsequent data analysis and backtracking of sampling results.

[0031] The pushing assembly includes a mounting block 41 fixedly connected to the inside of the rotating cylinder 11, a sliding plate 42 is slidably connected to the mounting block 41, a push plate 43 is slidably connected to the sliding plate 42, five push plates 43 are provided, and the push plates 43 are rotatably connected to the corresponding sampling cylinder 242, so that the push plates 43 can be prevented from interfering with the rotation of the sampling cylinder 242, a lifting rod 44 is slidably connected to the mounting seat 67, the lifting rod 44 penetrates the mounting seat 67 and extends to the inside of the rotating cylinder 11, and a guide plate 45 is symmetrically fixed to the lifting rod 44, the guide plate 45 is tilted, and a guide plate 45 is provided on the guide plate 45 There is a slide groove 451, and a fixed rod 46 is fixedly connected to the side wall of the sliding plate 42. The fixed rod 46 slides in the slide groove 451. With the fixed rod 46 as the base point, the guide plate 45 tilts to the lower left. The pushing assembly also includes an electric push rod 47 installed on the top surface of the mounting seat 67. A lifting ring 48 is fixedly connected to the telescopic rod of the electric push rod 47. The lifting ring 48 is provided with a second protrusion 481. The top of the lifting rod 44 is provided with a first protrusion 441 that matches the second protrusion 481, that is, the second protrusion 481 is arranged directly below the first protrusion 441, and the lifting rod 44 and the mounting seat 67 are connected. A third elastic member 49 is provided between the seats 67. The third elastic member 49 is specifically a spring. It can be seen that when the electric push rod 47 is started, the telescopic rod of the electric push rod 47 moves upward, thereby driving the lifting ring 48 to move upward. The second protrusion 481 on the lifting ring 48 contacts the first protrusion 441, and then the second protrusion 481 drives the first protrusion 441 to move upward, thereby driving the lifting rod 44 to move upward. The lifting rod 44 squeezes the third elastic member 49, so that the third elastic member 49 stores elastic potential energy. The lifting rod 44 moves upward while driving the guide plate 45 It moves upward, and then the slide groove 451 in the guide plate 45 squeezes the fixed rod 46, so that the fixed rod 46 moves, and then the fixed rod 46 drives the sliding plate 42 to slide on the mounting block 41, and then the push plate 43 pushes the sampling tube 242 to move, so that the sampling tube 242 extends out of the sampling slot group for sampling. When retracting, the telescopic rod of the electric push rod 47 moves downward, and then drives the lifting ring 48 to move downward, and the third elastic member 49 releases elastic potential energy, and then drives the lifting rod 44 to reset. The reset of the lifting rod 44 resets the push plate 43, and then drives the sampling tube 242 to reset.

[0032] The sampling slot group includes five sliding slots 111 arranged on the side wall of the rotating cylinder 11. The vertical length of the sliding slot 111 is greater than the moving range of the third sampler 23. Since the moving range of the third sampler 23 is the largest, the vertical length of the sliding slot 111 is greater than the moving range of the third sampler 23 to meet the moving range of all sampler groups. The first sampler 21, the second sampler 22 and the third sampler 23 are respectively arranged at the corresponding sliding slots 111. The shielding component includes a lifting block 51 slidably connected to the sliding slot 111. A folding baffle 52 is arranged between the lifting block 51 and the top of the corresponding sliding slot 111. The lifting block 51 and the corresponding sliding A second elastic member 53 is provided between the grooves 111, and the second elastic member 53 is specifically a spring. A slide bar 54 is slidably connected to the mounting seat 67, and the slide bar 54 passes through the sliding groove 111. The slide bar 54 is fixedly connected to the lifting block 51, and a lifting plate 55 is fixedly connected to the top of the slide bar 54. A guide box 56 is fixedly connected to the lifting ring 48, and a bending block 57 is slidably connected in the guide box 56. A first elastic member 58 is provided between the bending block 57 and the guide box 56, and the first elastic member 58 is specifically a spring. The bottom of the bending block 57 contacts the bottom surface of the lifting plate 55. The strength of the first elastic member 58 is greater than the strength of the second elastic member 53, and the first elastic member 58 is always in a compressed state, so that As is known, before the sampling tube 242 extends out, the sampling slot group needs to be opened first. Therefore, when the lifting ring 48 moves upward, before the second protrusion 481 contacts the first protrusion 441, since the strength of the first elastic member 58 is greater than the strength of the second elastic member 53, the second elastic member 53 will be compressed first to store elastic potential energy, that is, the first elastic member 58 will first abut against the bending block 57, so that the bottom of the bending block 57 will first lift the lifting plate 55 upward, thereby driving the sliding rod 54 to move upward, thereby driving the lifting block 51 to move upward, and then the lifting block 51 will fold one end of the folding baffle 52 upward first, thereby opening the sampling slot group. When the second protrusion 481 contacts the first protrusion 441, the second elastic member 53 will be compressed first to store elastic potential energy. That is, the first elastic member 58 will first abut against the bending block 57, thereby causing the bottom of the bending block 57 to first lift the lifting plate 55 upward, thereby driving the sliding rod 54 to move upward, thereby driving the lifting block 51 to move upward, and then the lifting block 51 will first fold one end of the folding baffle 52 upward, thereby opening the sampling slot group. When the first protrusion 441 contacts, the lifting block 51 reaches the limit distance of the top of the sliding groove 111, and the lifting plate 55 no longer moves upward. After the second protrusion 481 contacts the first protrusion 441 and drives the lifting rod 44 to move upward, the lifting plate 55 reacts with the bending block 57, so that the bending block 57 will no longer move upward, and then the bending block 57 squeezes the second elastic member 53, so that the second elastic member 53 stores elastic potential energy, so that the sampling slot group can be opened before the sampling tube 242 is extended. After sampling is completed, when the lifting ring 48 moves downward, the first elastic member 58 and the second elastic member 53 release the elastic potential energy, so that the bending block 57 and the lifting block 51 are reset.

[0033] A mounting slot 671 is provided in the mounting base 67, a power supply and a controller are installed in the mounting slot 671, a display 74 is installed on the mounting plate 63, the power supply is electrically connected to the electric push rod 47 and the second motor 31, and the controller is wirelessly connected to the display 74. By providing the power supply in this way, the wiring problem between the electric push rod 47 and the second motor 31 is avoided, and through the wireless connection between the controller and the display 74, some parameters can be displayed on the display 74, which is convenient for the operator to check.
