Description

Technical Field

[0001] The invention relates to the technical field of environmental detection sample sampling, and in particular to a multi-level sampling device based on environmental monitoring. Background Art

[0002] The main contents of environmental monitoring include: atmospheric environment monitoring, water environment monitoring, soil environment monitoring, solid waste monitoring, environmental biological monitoring, environmental radioactivity monitoring and environmental noise monitoring, etc. When monitoring the above different environments, sampling is carried out through corresponding sampling equipment, and the samples taken are tested and analyzed to detect the environment in real time.

[0003] Soil testing generally includes technical contents such as point sampling, sample preparation, analysis methods, result characterization, data statistics and quality evaluation. Therefore, when testing the soil environment, it is necessary to first sample the soil at different depths for comparative analysis.

[0004] Traditionally, when sampling soil at different depths, a shovel is usually used for digging. If a deeper soil sample is required, a large-scale equipment such as an excavator is directly used to dig up the entire soil layer. This not only increases the sampling cost, but also causes damage to the environment. The excavated soil is easily mixed together, making sampling difficult. In the prior art, a sampling drill is used to drive a sampling tube to be inserted into the soil to sample soil at different depths at one time. Compared with the traditional method of sampling soil at different depths, it is more convenient and quicker to dig and sample without using a large number of instruments. However, there are still certain problems when taking out the sample after sampling. In the prior art, mechanical vibration is combined with manual dumping to take out the sample soil in the sampling tube. For soil with high humidity, its viscosity is relatively large. After the soil sample is taken out by the above method, some soil will stick to the inner wall of the sampling tube. When sampling soil, sampling is usually performed at different positions in the same area. At this time, the sample soil stuck on the inner wall of the sampling tube will adhere to the surface of the obtained sample soil during the next sampling, resulting in inaccurate sample soil, and the results will be biased when performing soil testing. Summary of the invention

[0005] The purpose of the present invention is to overcome the problems in the prior art and provide a multi-level sampling device based on environmental monitoring to clean the soil stuck on the inner wall of the sampling tube to prevent it from adhering to the surface of the sample soil when sampling again, causing deviation in the detection results.

The drawings described in the present invention are only schematic diagrams of the structure.

[0024] The present invention provides a multi-level sampling device based on environmental monitoring, such as Figure 1 to Figure 3 As shown, it includes a sampling barrel 1 and a sampling drill bit 2 installed at the bottom of the sampling barrel 1. A cleaning component 3 for cleaning the sample soil pasted on the inner side of the sampling barrel 1 is provided in the sampling barrel 1. The cleaning component 3 includes a rotating rod 31. The rotating rod 31 is vertically arranged in the sampling barrel 1. The top of the rotating rod 31 is fixedly connected to the driving end of a driving member 34. A plurality of first connecting rods 32 are fixedly connected to the rotating rod 31. One end of each of the first connecting rods 32 is fixedly connected to a scraping plate 33. A wiping member 35 is provided in the sampling barrel 1. The plurality of wiping members 35 are used to wipe the inner wall of the sampling barrel 1 after scraping. A propulsion disk is fixedly connected to the bottom of the rotating rod 31.

[0025] After the sample soil is taken out from the sampling depth and taken out by mechanical vibration and manual pouring, the driving member 34 drives the rotating rod 31 to rotate and drives the wiping plate to move downward. First, the sample soil adhered to the inner wall of the sampling tube 1 is preliminarily scraped off by the wiping plate, and the rotating rotating rod 31 drives the scraping plate 33 to rotate together through the first connecting rod 32, so that the sample soil adhered to the inner wall of the sampling tube 1 is further scraped off by the scraping plate 33, so that the inside of the sampling tube 1 is cleaned to prevent the soil from adhering to the surface of the sample soil obtained when sampling again, which causes deviation in the detection result.

[0026] Preferably, Figure 1 to Figure 4 As shown, the scraper plate 33 is configured to be arc-shaped, and the side of the scraper plate 33 that is in contact with the inner wall of the sampling tube 1 is configured to be shovel-shaped, and a plurality of first connecting rods 32 are arranged in an array along the circumference of the rotating rod 31, and the plurality of first connecting rods 32 are not on the same horizontal plane.

[0027] In the present invention, the scraper plate 33 is set to be in an arc shape and fits the inner wall of the sampling tube 1, so that the sample soil adhered to the inner wall of the sampling tube 1 can be better scraped off. During sampling, the sample soil column is squeezed into the sampling tube 1. If the soil has a certain humidity, part of the sample soil is tightly attached to the inner wall of the sampling tube 1. The part of the stuck sample soil is scraped off by the wiping plate. At this time, the scraper plate 33 set in an arc shape scrapes off the remaining tightly stuck sample soil. In this embodiment, the scraper plate 33 is set to be in a shovel shape on one side that fits the inner wall of the sampling tube 1 to better scrape off the tightly stuck sample soil. The first connecting rods 32 are not in the same horizontal plane. When the first rotating rod 31 rotates, the scraper plates 33 set in an array can scrape the inner wall of the sampling tube 1 multiple times to scrape off the stuck sample soil.

[0028] Preferably, Figure 2-Figure 3 As shown, the wiping member 35 includes a rotating cylinder 351, which is rotatably sleeved on the rotating rod 31, and a plurality of second connecting rods 352 are fixedly connected to the circumference of the rotating cylinder 351. The plurality of second connecting rods 352 are all horizontally arranged and fixedly arranged in an array along the circumference of the rotating cylinder 351, and one end of the plurality of second connecting rods 352 is fixedly connected to a wiping plate 353, and a wiping cotton is attached to the wiping plate 353 by Velcro.

[0029] In the present invention, a rotating cylinder 351 is sleeved on the rotating rod 31. When the rotating rod 31 rotates, the second connecting rod 352 is driven to rotate through the rotating cylinder 351, and the wiping plate 353 is driven to rotate through the second connecting rod 352. The wiping cotton arranged on the outer side of the wiping plate 353 wipes the inner wall of the sampling tube 1 scraped by the scraping plate 33. Because the sample soil has a certain amount of moisture, part of the sample soil will remain only after being scraped by the scraping plate 33. The present invention cleans the remaining sample soil through the wiping cotton on the wiping plate 353, thereby improving the cleaning effect and ensuring the cleanliness of the sampling tube.

[0030] Preferably, Figure 2-Figure 3 As shown, the driving member 34 includes a cylinder 341, which is vertically fixedly connected to the sampling tube 1, and a support plate 342 is fixedly connected to the end of the cylinder 341, and a vertically arranged motor 343 is fixedly connected to the bottom of the support plate 342, and the rotating rod 31 is fixedly connected to the driving end of the motor 343. A connecting member 4 is provided on the support plate 342, and the connecting member 4 transmits the power generated by the motor 343 to the rotating cylinder 351, and makes the rotating cylinder 351 rotate in opposite directions to the rotating rod 31. The connecting member 4 includes a first gear 41, and the first gear 41 is fixedly sleeved on the output end of the motor 343. A second gear 42 is meshed on one side of the first gear 41, and the second gear 42 is rotatably connected to the support plate 342 through a third connecting rod 43. A fixing rod 44 is fixedly connected to the bottom of the second gear 42, and a third gear 45 is fixedly connected to the bottom of the fixing rod 44. A fourth gear 46 is meshed on one side of the third gear 45, and the fourth gear 46 is fixedly sleeved on the rotating cylinder 351.

[0031] In the present invention, the sampling tube 1 supports the set driving member 34, and the set supporting plate 342 is pushed forward by the cylinder 341, giving the wiping plate a downward moving force. When the motor 343 set on the supporting plate 342 rotates, it will drive the set rotating rod 31 to rotate, providing driving force for the rotating rod 31. In this embodiment, a connecting member 4 is provided, so that the wiping member 35 and the cleaning component 3 share a drive. When the motor 343 drives the rotating rod 31 to rotate, it will drive the sleeved first gear 41 to rotate, and the first gear 41 and the second gear 42 The second gear 42 is meshed, so that the second gear 42 rotates with the assistance of the third connecting rod 43. The rotating second gear 42 drives the third gear 45 to rotate through the fixed rod 44. The third gear 45 is meshed with the fourth gear 46. Since the fourth gear 46 is fixedly mounted on the rotating cylinder 351, the rotating cylinder 351 is rotated. When the two gears are meshed, the rotation directions are opposite. Therefore, the rotating rod 31 and the rotating cylinder 351 will rotate in opposite directions, so that the wiping plate 353 and the scraping plate 33 rotate in opposite directions, so that the residual sample soil can be better wiped.

[0032] Preferably, Figure 2-Figure 3As shown, a vibrating member 5 is fixedly connected to the support plate 342, and the vibrating member 5 includes a horizontally arranged bearing groove 51, and the bearing groove 51 is fixedly connected to the bottom of the support plate 342. A moving rod 52 is slidably connected in the bearing groove 51. An arc-shaped hammering block 53 is fixedly connected to the end of the moving rod 52 away from the motor 343, and an abutment block 54 is fixedly connected to the other end. A spring 55 is sleeved on the moving rod 52, and a cam 56 is fixedly sleeved on the driving end of the motor 343. The sampling drill bit 2 is detachably connected to the bottom of the sampling tube 1.

[0033] In this embodiment, a vibrating member is provided on the support plate 342. When the motor 343 is driven, the cam 56 is driven to rotate. When the cam 56 rotates to one side of the abutment block 54, the abutment block 54 is squeezed. At this time, the abutment block 54 drives the movable rod 52 to move, so that the arc-shaped hammering block 53 hammers the side wall of the sampling tube 1 and squeezes the spring 55 through the movable rod 52. The inner wall of the sampling tube 1 is hammered by the vibrating member 5, so that the inner wall of the sampling tube 1 generates a continuous vibration force, so that the attached sample soil is loosened, so that the scraping plate 33 can scrape off the sample soil.

[0034] Preferably, Figure 1 to Figure 5 As shown, the top of the sampling tube 1 is detachably connected to a driving end of a driving component 6 , and a drilling rig 7 is also provided, and the drilling rig 7 is detachably connected to the driving end of the driving component 6 .

[0035] When the present invention is performing soil sampling work, it can be selected whether the drilling rig 7 is needed to drill a hole according to the usage situation. For example, when it is necessary to sample 8m to 9m of sample soil, the drilling rig 7 is first installed on the driving end of the driving component 6 to drill an 8m deep hole. At this time, the drilling rig 7 is pulled out of the hole and the sampling tube 1 is installed on the driving end of the driving component 6. The sampling tube 1 only needs to advance 1m in the drilling depth to complete the sampling of the sample soil from 8m to 9m.

[0036] The method of using the multi-level sampling device based on environmental monitoring of the present invention is as follows:

[0037] After the sample soil is taken out from the sampling depth and taken out by mechanical vibration and manual dumping, the support plate 342 is pushed forward by the cylinder 341 to give the wiping plate a downward moving force. When the motor 343 arranged on the support plate 342 rotates, it drives the rotating rod 31 to rotate, providing driving force for the rotating rod 31, and drives the rotating rod 31 to rotate while driving the wiping plate to move downward. First, the sample soil attached to the inner wall of the sampling tube 1 is preliminarily scraped off by the wiping plate, and the rotating rod 31 in rotation drives the scraping plate 33 to rotate together through the first connecting rod 32, so that the sample soil attached to the inner wall of the sampling tube 1 is further scraped off by the scraping plate 33.

[0038] When the motor 343 drives the rotating rod 31 to rotate, it will drive the sleeved first gear 41 to rotate, the first gear 41 is meshed with the second gear 42, so that the second gear 42 is rotated with the assistance of the third connecting rod 43, and the rotating second gear 42 drives the set third gear 45 to rotate through the fixed rod 44, and the third gear 45 is meshed with the fourth gear 46. Since the fourth gear 46 is fixedly sleeved on the rotating cylinder 351, the rotating cylinder 351 is rotated, and the two gears rotate in opposite directions when meshing, the rotating cylinder 351 drives the second connecting rod 352 to rotate, and the set wiping plate is driven by the set second connecting rod 352 353 rotates, and the wiping cotton arranged on the outside of the wiping plate 353 wipes the inner wall of the sampling tube 1 scraped by the scraping plate 33. When the motor 343 is driven, the cam 56 is driven to rotate. When the cam 56 rotates to one side of the abutment block 54, the abutment block 54 is squeezed. At this time, the abutment block 54 drives the movable rod 52 to move, so that the arc-shaped beating block 53 beats the side wall of the sampling tube 1 and squeezes the spring 55 through the movable rod 52, and the inner wall of the sampling tube 1 is beaten by the vibrating member 5, so that the inner wall of the sampling tube 1 generates a continuous vibration force, so that the attached sample soil is loosened, so that the scraping plate 33 can scrape off the sample soil.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
