Description

Technical Field

[0001] The present application relates to the field of ecological restoration technology, and in particular to a detection device and method for environmental pollution control. Background Art

[0002] Environmental governance and environmental testing are becoming increasingly important on a global scale. As people pay more attention to environmental quality, countries have increased their investment in environmental protection and strengthened the monitoring and evaluation of environmental pollution and resource utilization. Environmental governance and environmental testing are not only related to public health and ecological balance, but also directly affect economic sustainable development and social stability. Environmental governance controls and reduces pollutant emissions, protects natural resources, and maintains ecological balance.

[0003] Environmental governance and environmental testing have become crucial in today's society. As people's attention to environmental issues continues to increase, all sectors are working hard to find effective ways to monitor and control environmental pollution to protect our planet and human health.

[0004] Environmental governance involves controlling and reducing pollutant emissions, protecting natural resources, and maintaining ecological balance, while environmental monitoring involves assessing environmental conditions and trends by monitoring the quality and changes of environmental elements such as the atmosphere, water, and soil. These data and information are of great significance for formulating environmental policies, planning urban development, and protecting ecosystems.

[0005] For example, a soil pollution detection device with publication number CN113985007A relates to the field of soil pollution. The prior art includes a shell, a first water storage chamber for storing clean water is provided above the shell, a second water storage chamber for moistening soil is provided inside the shell, the first water storage chamber and the second water storage chamber are connected by a water through port provided on the shell, a water inlet is provided above the shell, a soil-breaking rod that can slide up and down in the shell is provided below the shell, a soil-picking rod is provided at the center of the soil-breaking rod, a soil-picking rod is provided on the soil-picking rod for transporting soil, a filter plate fixedly connected in the soil-breaking rod is provided above the soil-picking blade, the soil-picking rod passes through the shell and abuts against the first water storage chamber, a support block is provided above the filter plate, a working cavity is formed between the support block and the filter plate, and residual soil in the detection device can be cleaned.

[0006] However, the above existing technologies still have some defects when detecting environmental pollution: 1. When conducting environmental pollution detection in the above-mentioned prior art, it is first necessary to insert a soil-breaking rod into the soil to test and sample the soil, and the soil-breaking rod must be reinserted into the soil for sampling each time the test is performed. When conducting soil sampling for environmental monitoring, it is usually necessary to take samples multiple times at different locations and to take samples regularly to ensure that comprehensive and accurate soil quality data is obtained. The sampling method of the above-mentioned prior art is labor-intensive.

[0007] 2. When the above-mentioned prior art is conducting environmental pollution detection, the soil-breaking rod is pressed into the outer shell, compressing the first spring. At this time, the water inlet pipe is connected to the second water storage chamber, and the water flows through the water inlet pipe and the branch pipe to the ground and the inside of the soil-breaking rod to soften the soil. When the water softens the soil, it may dilute the originally existing harmful substances, resulting in a lower concentration of harmful substances in the collected soil samples, affecting the accuracy of the test results; at the same time, softening the soil may lead to the redistribution of soil particles, causing the original sampling position to change, resulting in the sampled soil not representing the actual situation, thereby affecting the accurate assessment of the degree of pollution; and the injection of water may bring new pollutants, or diffuse the original pollutants along the water flow path, thereby introducing new interference factors and affecting the accuracy of the sample.

DETAILED DESCRIPTION

[0035] The following is combined with Figures 1 to 13 This application is described in further detail.

[0036] The embodiment of the present application discloses a detection device and method for environmental pollution control, which samples the soil by drilling holes, and then screens and crushes the soil to unify the size of soil particles, thereby improving the reliability and accuracy of the detection results. Example

[0037] Reference Figure 1 and Figure 2A detection device for environmental pollution control includes a self-propelled vehicle 1, a support box 2 is arranged in the self-propelled vehicle 1, and a feeding hole 21 is opened on one side of the support box 2. First, the self-propelled vehicle 1 is placed in a target area that needs to be detected, and then the self-propelled vehicle 1 will move in the target area and advance to the target position where sampling is required. After reaching the predetermined position, a soil sampler 3 located on one side of the feeding hole 21 arranged in the self-propelled vehicle 1 is started. The soil sampler 3 will sample the soil and detect the sampled soil, and then transmit the detection result back to the terminal. At this point, a sampling detection of the environment is completed.

[0038] The process of repeating multiple sampling and testing in the target area can obtain more data points through multiple sampling and testing, increase the credibility and reliability of the data. Sampling points in different locations may have spatial heterogeneity. Repeated sampling can provide a more comprehensive understanding of the environmental pollution situation in the target area, thereby improving the efficiency of environmental testing and facilitating real-time monitoring of the environment in the target area.

[0039] Specifically, refer to Figures 3 to 5 The soil sampler 3 includes a support tube 32 arranged at the bottom of the self-propelled vehicle 1, and the lower end of the support tube 32 passes through the bottom of the self-propelled vehicle 1. After the self-propelled vehicle 1 reaches the predetermined position, the driving member 31 arranged on the support box 2 will be started, and the driving member 31 will drive the sampling tube 321 passing through the support tube 32 to rotate. The rotating sampling tube 321 will move downward through the threaded connection of the support tube 32, and drive the cutting ring 33 arranged at the lower end of the sampling tube 321 to move together. The cutting saw teeth 331 arranged at the lower end of the cutting ring 33 will rotate and cut the soil on the ground under the drive of the sampling tube 321, so that the soil enters the sampling tube 321.

[0040] At the same time, the sampling tube 321 will drive the sampling cover 34 rotatably arranged on its upper end to move downward together, and the sampling cover 34 is rotatably penetrated by a sampling drill rod 35 located in the sampling tube 321, and the sampling drill rod 35 is coaxial with the sampling tube 321 and the sampling cover 34, and the sampling cover 34 is provided with a driving motor 352 connected to the sampling drill rod 35, and the driving motor 352 will drive the sampling drill rod 35 to rotate, and the sampling drill rod 35 will drive the spiral blade 351 arranged thereon and located in the sampling tube 321, and the edge of the spiral blade 351 contacts the inner wall of the sampling tube 321, and the spiral blade 351 will transport the soil in the sampling tube 321 upward to the sampling cover 34, and then through the feeding frame 341 slidably arranged in the feeding hole 21 and connected to the sampling cover 34, so that the soil in the sampling cover 34 enters the supporting box 2 from the feeding frame 341.

[0041] After sampling is completed, the driving member 31 will drive the sampling tube 321 to reverse, and the rotating sampling tube 321 will move upward through the threaded connection of the support tube 32 and return to its initial state. During this process, the flexible baffle 342 slidingly arranged in the feed hole 21 and connected to the feed frame 341 will move in the feed hole 21 together with the feed frame 341, and always block the feed hole 21 to prevent soil from falling out of the support box 2.

[0042] The driving member 31 will drive the two conveying shafts 36 that are rotatably installed on the support box 2 to rotate. After the soil enters the support box 2, it will fall onto the conveyor belt 361 that is sleeved between the two conveying shafts 36. The conveyor belt 361 will transport the soil to the discharge port 37 opened on the support box 2 on the side of the conveyor belt 361 away from the feed hole 21, and then enter the discharge frame 371 connected to the discharge port 37 set on the support box 2 from the discharge port 37. After passing through the discharge frame 371, the soil will enter the discharge frame 372 connected to the discharge frame 371 set in the support box 2, and then be discharged from the discharge port 373 opened at the bottom of the discharge frame 372 and penetrating to the self-propelled vehicle 1.

[0043] In the process of the soil passing through the discharge frame 371 and entering the discharge frame 372, smaller soil will pass through the sieve hole 374 opened at the bottom of the discharge frame 371, and then enter the guide frame 375 set at the lower end of the discharge frame 371, and be discharged from the feed port 376 opened on the support box 2 and connected to the guide frame 375 under the guidance of the guide frame 375; by screening and crushing the soil, the size of the soil particles can be unified, and the removal of large impurities is beneficial to the accuracy of subsequent analysis and test results. Uniform soil samples can reduce experimental errors and improve the reliability and repeatability of test results.

[0044] Reference Figures 6 to 9 A partition plate 39 is provided in the support box 2 below the conveyor belt 361. The soil discharged from the feed port 376 will enter into a crushing chamber 391 formed between one end of the partition plate 39 facing the guide frame 375 and the support box 2, and then will be crushed and sampled by the sample retaining part 4 provided in the crushing chamber 391.

[0045] Among them, the sample retention part 4 includes a crushing shaft 41 which is symmetrically and rotatably arranged in the crushing chamber 391. The driving part 31 will drive the crushing shaft 41 to rotate. The rotating crushing shaft 41 will drive the crushing roller 411 arranged thereon and located in the crushing chamber 391 to rotate relatively. The rotating crushing roller 411 will crush the soil falling into the crushing chamber 391, and then fall into the guide funnel 42 arranged in the crushing chamber 391 and located below the crushing roller 411.

[0046] A material receiving port 43 is provided on the support box 2 at one side of the guide funnel 42, and a support plate 44 is provided at the upper end of the material receiving port 43. A support shaft 45 is rotatably passed through the support plate 44, and a sample retaining plate 47 is provided on the support shaft 45. A plurality of sample retaining tanks 48 are evenly arranged circumferentially on the sample retaining plate 47. The lower end of the guide funnel 42 penetrates the support plate 44 and contacts with the upper end of the sample retaining tank 48. A soil analyzer 49 is provided on the support plate 44 and is located directly above one of the sample retaining tanks 48.

[0047] After the crushed soil falls into the guide funnel 42, it enters the sample tank 48 directly below the guide funnel 42. After the sample is collected, the servo motor 46 connected to the support shaft 45 arranged on the support plate 44 will be started, and the servo motor 46 will drive the support shaft 45 to drive the sample plate 47 to rotate. The rotating sample plate 47 will drive the sample tank 48 to rotate one station, and the support plate 44 will block the outlet of the sample tank 48 to prevent the soil from being exposed or spilled. At this time, the sample tank 48 containing the soil sample will move to the bottom of the soil analyzer 49, and the soil analyzer 49 will detect the soil in the sample tank 48 and transmit the detection results back to the terminal. At this point, a sampling test of the environment is completed.

[0048] Among them, the driving member 31 includes a driving gear 1 311 rotatably arranged on the upper end of the supporting tube 32 and slidably connected to the sampling tube 321. After the self-propelled vehicle 1 reaches the predetermined position, the driving motor 312 arranged on the supporting tube 32 through the bracket will be started, and the driving motor 312 will drive the driving gear 2 313 arranged on its driving end to rotate; the driving gear 2 313 drives the driving gear 1 311 to rotate by meshing with the driving gear 1 311, and the rotating driving gear 1 311 will drive the sampling tube 321 to rotate, thereby realizing the up and down movement of the sampling tube 321 and sliding on the driving gear 1 311.

[0049] By means of the existing motor driving technology, one of the conveying shafts 36 or one of the crushing shafts 41 provided on the supporting box 2 is driven to rotate, and one of the conveying shafts 36 or one of the crushing shafts 41 connected thereto is driven to rotate. Since the two conveying shafts 36 are connected by a belt drive, and one of the conveying shafts 36 and one of the crushing shafts 41 are connected by a belt drive, that is to say, when any one of the conveying shafts 36 or one of the crushing shafts 41 rotates, any one of the rotating conveying shafts 36 or one of the crushing shafts 41 will drive the remaining conveying shafts 36 and one of the crushing shafts 41 to rotate through the belt drive, thereby realizing the conveying of the conveyor belt 361.

[0050] The two crushing shafts 41 are connected via gear meshing transmission. When one of the crushing shafts 41 rotates, the rotating crushing shaft 41 drives the other crushing shaft 41 via gear meshing transmission, thereby achieving relative rotation of the crushing shafts 41.

[0051] It should be noted that the cutting ring 33 may be damaged during long-term sampling work, and the sampling tube 321 and the cutting ring 33 can be replaced in a detachable connection.

[0052] The sample tray 47 and the sample tank 48 are detachably connected. By removing the sample tank 48 and replacing it with a new one, the soil sample therein can be further tested or sampled to ensure the accuracy of the test results; and after replacing the new sample tank 48, the self-propelled vehicle 1 can continue to work. Example

[0053] Reference Figure 7 On the basis of the first embodiment, a sieve plate 38 is slidably arranged between the discharging frame 371 and the guide frame 375, an adjusting screw 381 threadedly connected to the sieve plate 38 is rotatably penetrated on the support box 2, an adjusting motor 382 connected to the adjusting screw 381 is arranged in the support box 2, and an adjusting hole 383 corresponding to the sieve hole 374 is arranged on the sieve plate 38. The adjusting motor 382 drives the adjusting screw 381 to rotate, and the adjusting screw 381 drives the sieve plate 38 to move between the discharging frame 371 and the guide frame 375 through the threaded connection, so that the adjusting hole 383 and the sieve hole 374 overlap and open, or the adjusting hole 383 and the sieve hole 374 are staggered and blocked with each other, so as to change the size of the screened soil.

[0054] At the same time, after the sampling tube 321 completes sampling, the adjusting holes 383 and the sieve holes 374 are blocked with each other by adjusting the motor 382, ​​and the excess soil is discharged from the discharge port 373. Example

[0055] Reference Figures 10 to 13 On the basis of the first and second embodiments, in order to ensure the stability of the self-driving vehicle 1 during the sampling process, a fixture 5 for fixing the self-driving vehicle 1 is provided inside the self-driving vehicle 1 .

[0056] Specifically, the fastener 5 includes a plurality of fixed cylinders 51 symmetrically distributed in a matrix at the bottom of the self-driving vehicle 1, the lower end of the fixed cylinder 51 passes through the self-driving vehicle 1, a fixed shaft 52 with a hollow structure is passed through the fixed cylinder 51 and is threadedly connected to the fixed cylinder 51, and the plurality of fixed shafts 52 are connected by belt transmission.

[0057] A transmission motor 53 is provided on one of the fixed cylinders 51 through a bracket, and the transmission motor 53 is connected to one of the fixed shafts 52 through a belt transmission. After the self-propelled vehicle 1 reaches a predetermined position, the transmission motor 53 rotates and drives one of the fixed shafts 52 to rotate through the belt transmission connection. The multiple fixed shafts 52 rotate synchronously through the belt transmission connection, and the auger blades 54 arranged in the fixed cylinder 51 on the rotating fixed shaft 52 rotate together.

[0058] At the same time, the rotating fixed shaft 52 moves downward through the threaded connection with the fixed cylinder 51, and drives the fixing part 6 set at the lower end of the fixed shaft 52 to move, and the auger blades 54 will drill into the soil to ensure the stability of the self-driving vehicle 1 during the sampling process, until the fixed shaft 52 drives the auger blades 54 to completely enter the soil and the driving motor 312 stops rotating, and the fixing part 6 set at the lower end of the fixed shaft 52 will be fixed in the soil by spreading.

[0059] After the sampling tube 321 completes sampling, the fixing part 6 is retracted, and then the driving motor 312 is reversed, and one of the fixed shafts 52 is driven to rotate through the belt transmission connection. The multiple fixed shafts 52 are synchronously reversed through the belt transmission connection, and the rotating fixed shaft 52 will drive the auger blade 54 to rotate together. At the same time, the rotating fixed shaft 52 moves upward through the threaded connection with the fixed cylinder 51, and drives the fixing part 6 set at the lower end of the fixed shaft 52 to move, and the auger blade 54 will withdraw from the soil until it returns to the initial state, ensuring that the self-propelled vehicle 1 can continue to move.

[0060] Among them, the fixing part 6 includes a plurality of conical lobes 61 hinged at the bottom of the fixed shaft 52, the conical lobes 61 are hinged with a connecting rod 62, an electric push rod 63 is arranged in the hollow structure of the fixed shaft 52, and a connecting push rod 64 hinged with the connecting rod 62 is arranged on the telescopic end of the electric push rod 63.

[0061] After the transmission motor 53 stops rotating, the electric push rod 63 starts to drive the connecting push rod 64 to move downward, and the connecting push rod 64 will drive the connecting rod 62 to move together, causing it to rotate around the hinge point of the connecting push rod 64. At the same time, since the connecting rod 62 and the conical leaf petals 61 are hingedly connected, the conical leaf petals 61 will also rotate with it, so that the conical leaf petals 61 at the lower end of the fixed shaft 52 will rotate around the hinge point of the fixed shaft 52 and open to fix the fixed shaft 52 in the soil.

[0062] On the contrary, the electric push rod 63 starts and drives the connecting push rod 64 to move upward, and the connecting rod 62 is pulled by the connecting push rod 64, so that the connecting rod 62 pulls the conical leaf 61 to rotate through the hinge between the conical leaf 61, so that the folding of the conical leaf 61 releases the soil, so that the fixed shaft 52 can be moved out of the soil to release the fixation of the self-driving vehicle 1. Example

[0063] Reference Fig.12 and Fig.13 On the basis of the third embodiment, a plurality of conical lobes 61 form a fixed cone 65, and a needle-shaped soil detector 66 penetrating the fixed cone 65 is provided at the lower end of the connecting push rod 64. When the connecting push rod 64 moves downward, it drives the soil detector 66, inserts the soil detector 66 into the soil for detection, and transmits the detection result back to the terminal.

[0064] Each soil detector 66 has different functions, such as a soil moisture detector, a soil compaction meter, and a soil water content detector. Soil detectors 66 with different functions can be tested through the same system, such as soil moisture, compaction, water content, and other indicators, to achieve multifunctional and comprehensive soil monitoring. By inserting the detector into the soil by moving the connecting push rod 64 downward, the accuracy and reliability of the detection can be ensured, human errors can be avoided, and the accuracy of the data can be improved. Example

[0065] Reference Figure 1 On the basis of the fourth and fifth embodiments, when the wind speed is too high, the self-driving vehicle 1 is at risk of being blown over, so a wind speed sensor 11 is provided on the self-driving vehicle 1. When the wind speed sensor 11 detects that the wind speed is too high, the self-driving vehicle 1 will stop, and then start the transmission motor 53 to make the fixed shaft 52 move in and out of the soil for fixation, thereby preventing the self-driving vehicle 1 from being blown over. Example

[0066] Reference Figure 1 On the basis of the fourth and fifth embodiments, a sound recorder 12 is provided on the self-driving vehicle 1 to record the presence and activities of wild animals so as to assess the health status of biodiversity and ecosystem.

[0067] Finally, the present invention also provides a detection method for environmental pollution control, and its use method comprises the following steps: S1: Detection preparation, firstly, the self-driving vehicle 1 is placed in the target area to be detected, and then the self-driving vehicle 1 moves in the target area and moves toward the target position where sampling is required.

[0068] S2: Sampling and fixing. After reaching the predetermined position, the fixer 5 is started to drill the fixing shaft 52 into the soil. The fixing member 6 at the lower end of the fixing shaft 52 is fixed in the soil by being stretched.

[0069] S3: Drilling and sampling, then the soil sampler 3 will be started, sampling by drilling, screening and crushing the sampled soil, and then storing and testing the soil, and then transmitting the test results back to the terminal.
