Description

Technical Field

[0001] The present invention relates to the technical field of soil sampling and monitoring, and in particular to a method for monitoring the environmental impact of land space planning. Background Art

[0002] Land space planning refers to the planned arrangement for the rational use, protection and management of land resources in a country or region. It involves many aspects such as urban and rural development, economic and social development, and ecological and environmental protection, aiming to achieve the sustainable development goals of a country or region. In the process of land space planning, due to the involvement of various construction projects, it is bound to cause certain damage to the local ecological environment, that is, to change the original ecological environment. In order to monitor the impact on the ecological environment as much as possible, environmental impact monitoring equipment is generally installed to conduct regular monitoring of environmental impacts.

[0003] For example, Chinese patent CN117607470B discloses a land space planning environmental impact monitoring device. It can be seen that the device can be inserted obliquely into the soil and extract part of the soil by setting the suction pipe and the bucket on the same side respectively, and using the negative pressure of the obliquely installed bucket and the suction pipe in the initial state. At the same time, the water sample can be absorbed by the negative pressure. The whole process is completed quickly without the need for manual cooperation of external devices. Water samples and soil samples can be automatically sampled regularly without human intervention, which significantly improves the monitoring efficiency.

[0004] Based on the prior art search, the soil sampled by the environmental monitoring sampling device in the prior art for analysis and monitoring generally has the problem of inaccurate soil analysis. For example, when the above-mentioned equipment is used, After soil sampling, some soil remains in the sampling device, causing the soil to mix with each other during the next sampling, affecting the analysis accuracy. In addition, the soil after sampling is exposed to the outside world and is easily blown off, resulting in insufficient sampling volume. Secondly, since the soil sampling device drills directly from the surface to take samples, the loose soil on the surface of the soil that is easy to move will also be collected, further affecting the subsequent analysis accuracy.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] For example, see Figure 1-7 The present invention provides a method for monitoring the environmental impact of land space planning as follows: First, when sampling, the electric push rod 4 drives the sampling box 5 to descend and pass through the sampling slot 7. When the bottom of the sampling box 5 contacts the soil surface, as the sampling box 5 goes deeper, the soil squeezes the two closing plates 601, causing the two closing plates 601 to rotate toward the inside of the sampling box 5. At this time, the sampling box 5 is in an open state, so as the sampling box 5 goes deeper, the soil will be squeezed into the inside of the sampling box 5, completing the collection and sampling. When sampling is completed, the electric push rod 4 drives the sampling box 5 to rise. At this time, the soil no longer squeezes the two closing plates 601, and the elastic force of the torsion spring 603 is used to reset, automatically driving the two closing plates 601 to merge, so as to close the sampling box 5 and prevent the soil after sampling from being exposed to the outside world. When the sampling box 5 returns to the initial position, the driving motor 21 drives the toothed disc 3 to rotate, and the sampling box 5 is rotated to the position corresponding to the rear side of the support plate 1, that is, the position aligned with the storage box 12. At this time, the electric push rod 4 drives the sampling box 5 to continue to rise. At this time, the soil inside the sampling box 5 will be squeezed against the first spring 609 by the scraper 604, so that the elastic force of the first spring 609 can be used to drive the scraper 604 to scrape the inner wall of the sampling box 5. At the same time, the two scraper strips 606 are used to squeeze the upper surfaces of the two closing plates 601. The two closing plates 601 are rotated and opened toward the outside of the sampling box 5, so that most of the soil inside the sampling box 5 falls from the inside of the sampling box 5 through the placement groove 11 and falls into the storage box 12. At the same time, during the rising process of the sampling box 5, the scraper 604 and the scraper strip 606 can be used to scrape the inner wall of the sampling box 5 and the surface of the closing plate 601 to avoid part of the soil remaining in the sampling device. Then, a soil detector is arranged inside the storage box 12, so that the soil taken out can be tested by the soil detector; Then, before the sampling box 5 descends to the soil surface, when the bottom of the sampling box 5 contacts the upper inclined surfaces of the two cleaning blocks 803, the inclined surfaces can be used to guide the two cleaning blocks 803 to separate from each other and scrape and clean the soil surface at the descending position. Then, after the toothed disc 3 rotates one circle, the first bevel gear 16 can be used to drive a pair of moving wheels 15 to rotate, thereby driving the entire device to move and avoiding repeated sampling at the same position.

[0024] Among them, the top of the support plate 1 is fixedly connected with a bracket 2, and a toothed disc 3 is arranged at the center of the top inner wall of the bracket 2, an electric push rod 4 is fixedly installed at the eccentric position of the bottom of the toothed disc 3, and an output rod at one end of the electric push rod 4 is fixedly connected with a sampling box 5, and a sampling slot 7 is opened on the front side wall of the support plate 1; The inner wall of the sampling box 5 is provided with a protective pushing mechanism 6. Further, the protective pushing mechanism 6 includes a closing plate 601, and the interior of the closing plate 601 is fixedly connected with a shaft 602. The inner wall of the sampling box 5 is provided with a groove 9 corresponding to the shaft 602, and the two ends of the shaft 602 are rotatably connected to the inner wall of the groove 9. The outer walls of the two ends of the shaft 602 are provided with torsion springs 603, one end of the torsion spring 603 is overlapped on the outer wall of the shaft 602, and the other end of the torsion spring 603 is overlapped on the inner wall of the groove 9. In this embodiment, when sampling is performed, first, the shaft rod 602 is fixedly connected to the inside of the closing plate 601, and the inner wall of the sampling box 5 is provided with a groove 9 corresponding to the shaft rod 602, and the two ends of the shaft rod 602 are rotatably connected to the inner wall of the groove 9, and at the same time, the outer walls of the two ends of the shaft rod 602 are provided with torsion springs 603, and one end of the torsion spring 603 is overlapped on the outer wall of the shaft rod 602, and the other end of the torsion spring 603 is overlapped on the inner wall of the groove 9, so that the torsion springs 603 can be used to keep the two closing plates 601 in a horizontal state, that is, a closed state; Then, the electric push rod 4 is started, and the sampling box 5 is fixedly connected to the output rod at one end of the electric push rod 4, and a sampling groove 7 is opened on the front side wall of the support plate 1, so that the sampling box 5 can be driven by the electric push rod 4 to descend and pass through the sampling groove 7. When the bottom of the sampling box 5 contacts the soil surface, as the sampling box 5 goes deeper, the soil squeezes the two closing plates 601, so that the two closing plates 601 rotate toward the inside of the sampling box 5. At this time, the sampling box 5 is in an open state, so as the sampling box 5 continues to go deeper, the soil will be squeezed into the inside of the sampling box 5, and the sampling is collected; When sampling is completed, the electric push rod 4 drives the sampling box 5 to rise. At this time, the soil no longer squeezes the two closing plates 601, and the elastic force of the torsion spring 603 is used to reset, automatically driving the two closing plates 601 to merge, so as to close the sampling box 5 and prevent the soil after sampling from being exposed to the outside world. When the sampling box 5 returns to its initial position, that is, it is consistent with the horizontal height of the support plate 1, at this time, a driving motor 21 is fixedly installed through the top outer wall of the bracket 2, and the output shaft at one end of the driving motor 21 passes through the interior of the bracket 2 and is fixedly connected to the top center of the toothed disc 3, and an electric push rod 4 is fixedly installed at the bottom eccentric position of the toothed disc 3, so that the driving motor 21 can be used to drive the toothed disc 3 to rotate, and the sampling box 5 is rotated to the position corresponding to the rear side of the support plate 1, that is, the position aligned with the storage box 12. At this time, a scraper 604 is fitted through the top inner wall of the sampling box 5, and a connecting column 607 is fixedly connected to the top of the scraper 604, and a connecting cylinder 608 is fitted and slidably connected to the outer wall of the connecting column 607, and the connecting cylinder 608 is fitted and slidably connected. The top of the column 607 is fixedly connected with a first spring 609, and the other end of the first spring 609 is fixedly connected to the top inner wall of the connecting tube 608, and the outer wall of the connecting column 607 slides in contact with the inner wall of the through groove 10, so that the connecting column 607 and the first spring 609 are used to realize the follow-down of the scraper 604 during the descent of the sampling box 5. When the sampling box 5 is at the same level as the support plate 1, the first spring 609 is in a normal state, and the sampling box 5 is driven to continue to rise by the electric push rod 4. At this time, the soil inside the sampling box 5 will be squeezed against the first spring 609 by the scraper 604, so that the elastic force of the first spring 609 can be used to drive the scraper 604 to scrape the inner wall of the sampling box 5; Then, a connecting rod 605 is symmetrically fixedly connected to the bottom of the scraper 604, and a scraper strip 606 is fixedly connected to the bottom of the connecting rod 605, and the bottom of the scraper strip 606 is inclined, so that when the sampling box 5 rises, the two combined closing plates 601 will be synchronously driven to rise, and then the two scraper strips 606 can be used to squeeze the upper surfaces of the two closing plates 601, so that the two closing plates 601 can be rotated and opened to the outside of the sampling box 5, so that most of the soil inside the sampling box 5 falls from the inside of the sampling box 5 through the placement groove 11 and falls into the storage box 12. At the same time, during the rising process of the sampling box 5, the scraper 604 and the scraper strip 606 can be used to scrape the inner wall of the sampling box 5 and the surface of the closing plate 601 to avoid part of the soil remaining in the sampling device. Then, a soil detector is arranged inside the storage box 12, so that the soil detector can be used to detect the taken out soil; Then, after the sampling box 5 rises to the highest point, the soil inside the sampling box 5 is taken out, and then the sampling box 5 is driven by the electric push rod 4 to descend until it is consistent with the horizontal height of the support plate 1. At this time, the closing plate 601 is closed again, and then the sampling box 5 is driven by the driving motor 21 again to return to the position of the sampling slot 7, waiting for the next sampling test; By the above, when sampling is performed, the sampling box 5 can be driven to descend and the soil can be collected and sampled by the electric push rod 4. The torsion spring 603 can be used to drive the two closing plates 601 to merge during the ascending process and when moving to the storage box 12, so as to close the sampling box 5 and avoid the soil after sampling being exposed to the outside world and easily blown off, resulting in insufficient sampling volume. At the same time, when preparing for detection, the sampling box 5 can be driven to ascend by the electric push rod 4, and the scraper 604 and the scraper strip 606 can be used to automatically open the closing plate 601, and the inner wall of the sampling box 5 and the surface of the closing plate 601 can be scraped to avoid the presence of some soil remaining in the sampling device, thereby ensuring the accuracy of subsequent detection and analysis.

[0025] Embodiment 2, on the basis of the above embodiment, a soil cleaning mechanism 8 is provided at the bottom of the support plate 1, further, the soil cleaning mechanism 8 includes a fixed block 801, and the top of the fixed block 801 is fixedly connected to the bottom of the support plate 1, the fixed block 801 is slidably connected with a slide rod 802 inside, the end of the two slide rods 802 close to each other is fixedly connected with a cleaning block 803, the top of the cleaning block 803 is inclined, the end of the two slide rods 802 away from each other is fixedly connected with a connecting ring 804, the outer wall of the end of the two slide rods 802 away from each other is provided with a second spring 805, one end of the second spring 805 is fixedly connected to a side wall of the connecting ring 804, and the other end of the second spring 805 is fixedly connected to a side wall of the fixed block 801; In this embodiment, when sampling, before the sampling box 5 is lowered to the soil surface, a slide bar 802 is connected to the fixed block 801 through internal sliding, and the ends of the two slide bars 802 close to each other are fixedly connected to a cleaning block 803, and the top of the cleaning block 803 is inclined, and the outer wall of the ends of the two slide bars 802 away from each other is provided with a second spring 805, so that the second spring 805 can be used to drive the two cleaning blocks 803 to fit each other. When the upper inclined surface of the sampling box 5 contacts, the inclined surface can be used to guide the two cleaning blocks 803 to separate from each other, and the soil surface layer at the descending position can be scraped and removed to prevent the loose soil on the soil surface from being collected. The top of the sampling box 5 is symmetrically fixedly connected to the corresponding soil layer cleaning mechanism 8, so that during the descent process, the two cleaning blocks 803 can be limited and separated by the two auxiliary plates 610, so that the descent depth of the sampling box 5 can be higher, thereby increasing the sampling amount of the soil; Then, a support block 13 is symmetrically fixedly connected to the bottom of the support plate 1, and a support rod 14 is rotatably connected to the inside of the support block 13, and moving wheels 15 are fixedly connected to the two ends of the support rod 14, so that the device can be supported by two pairs of moving wheels 15, and at the same time, a first bevel gear 16 is symmetrically fixedly connected to the outer wall of one of the support rods 14, and a second bevel gear 17 is meshed with a side wall of the first bevel gear 16, and a rotating rod 18 is fixedly connected to the inner center of the second bevel gear 17, and at the same time, a driven gear 19 is fixedly connected to the top outer wall of the rotating rod 18, and a side wall of the driven gear 19 is meshed and matched with the outer wall gear teeth of the toothed disc 3, and the outer wall of the rotating rod 18 is rotatably connected to the inner wall of the rotating groove 20, so that after the toothed disc 3 rotates one circle, the first bevel gear 16 can be used to drive a pair of moving wheels 15 to rotate, so that the device can be driven to move as a whole to avoid repeated sampling of the same position; By doing as above, when sampling is performed, before the sampling box 5 descends to the soil surface, the two combined cleaning blocks 803 can be used to scrape and clean the soil surface at the descending position, so as to avoid the loose soil on the soil surface that is easy to move from being collected, thereby further ensuring the accuracy of subsequent detection and analysis. At the same time, after the sampling is completed, the toothed disc 3 is used to drive one of the pairs of moving wheels 15 to rotate, thereby driving the entire device to move, thereby avoiding repeated sampling at the same position, resulting in less soil at that position affecting the sampling efficiency, and being able to expand the sampling range, which is beneficial to improving the authenticity and reliability of subsequent soil detection and analysis results, and improving the monitoring effect of the environment.
