Description

TECHNICAL FIELD

[0001] The application relates to the technical field of soil sampling, and in particular to a river embankment soil sampling device for intelligent water conservancy. BACKGROUND

[0002] The river embankment in intelligent water conservancy is an intelligent water conservancy engineering system constructed by integrating modern information technologies (such as the Internet of Things, big data, artificial intelligence, sensors, etc.) on the basis of traditional flood control embankments. The core goal is to achieve precise perception, intelligent early warning and efficient management of the whole life cycle of the embankment. The collection and processing of soil samples are important prerequisites for the correctness of soil detection data. Collecting representative samples is a prerequisite for accurately reflecting soil nutrient conditions, mechanical composition, structure and organic matter content. Sampling generally uses five-point sampling and three-point sampling methods. Five-point sampling is also known as "quincunx sampling method"; three-point sampling is generally diagonal sampling. Which method to use depends on the area of the land and the requirements, and then the soil detection samples are taken back to the laboratory for accurate analysis. The river embankment of water conservancy may be loose due to long-term water erosion, etc., which has a great safety hazard, so it is necessary to regularly sample and analyze the embankment soil to ensure the safety of the embankment.

[0003] Manual drill rod sampling: the most common way. Relying on manpower to use Luoyang spades, hand-operated augers and other tools to drill into the soil layer and manually take out the soil sample. Characteristics: simple equipment, low cost; significant shortcomings: low efficiency, high labor intensity, sampling depth and consistency are greatly affected by the operator, poor layering accuracy, difficult to operate in steep slopes or complex terrain, safety hazards (such as hole collapse, insects and snakes).

[0004] Vehicle-mounted or large platform sampling: using hydraulic or mechanical drillers mounted on vehicles or large platforms for sampling. Characteristics: can obtain deeper and harder soil samples, high efficiency; significant shortcomings: large size, poor mobility, difficult to operate in narrow embankment tops, slopes or soft beaches, large disturbance to embankment structure, high cost, difficult to achieve fine layering sampling.

[0005] Small electric / gasoline-powered samplers: portable devices using electric motors or gasoline engines to drive drill rods or impact hammers for sampling. Characteristics: higher efficiency than pure manpower, certain portability; significant shortcomings: usually only shallow or highly disturbed sampling, inaccurate layering control, low automation (still requiring manual operation and soil removal), data recording relying on manual work, easy to get stuck and damaged when encountering hard objects or tree roots.

[0006] Traditional equipment can only obtain a single depth sample per drilling, and repeated drilling is required to collect different soil layers, which is low in efficiency and destroys the soil structure, lacks effective isolation mechanism, and different depth soils are easily mixed during collection or removal, affecting detection accuracy.

[0013] Preferably, the bottom inner wall of the sampling cylinder is rotatably provided with a hollow rod through a bearing, and the outer side of the hollow rod is fixedly provided with a sampling cylinder, and the outer side of the sampling cylinder is provided with three sampling grooves, and the included angle between the three sampling grooves is 60 degrees, and the three sampling grooves are matched with the sampling hole.

[0014] Preferably, the drill bit mechanism comprises a conical drill bit and a rotary motor, the rotary motor is fixedly installed at the center of the bottom of the sampling cylinder, the top of the conical drill bit is provided with a motor connecting groove, the output shaft of the rotary motor is fixedly installed with the bottom inner wall of the motor connecting groove, the top of the conical drill bit is provided with a sealing ring groove, and the bottom of the sampling cylinder is fixedly provided with a sealing ring, and the sealing ring is slidably connected with the inner wall of the sealing ring groove.

[0018] In the application, the river embankment soil collecting device for intelligent water conservancy has the beneficial effects that: 1. Multi-depth stratified in-situ sampling and pollution isolation: the unique designed sampling mechanism (sampling cylinder + rotary sampling cylinder) cooperates with the handle rotation locking mechanism, so that three different depth soil samples can be in-situ and continuously collected in a single drilling process, and the samples are physically isolated in the sampling grooves, so that the cross contamination of different soil layers is effectively avoided. This is the most core innovation.

[0019] 2. Integrated rotary soil breaking and sealing anti-leakage: The independent rotary drill bit (conical drill bit + rotary motor) is directly integrated at the bottom center of the sampling cylinder to achieve efficient soil breaking. Through the sliding fit of the sealing ring and the sealing ring groove, the impurities such as soil and water are effectively prevented from entering the inside of the sampling cylinder when the drill bit is rotating at high speed, thereby protecting the internal mechanism and ensuring the purity of the sample.

[0020] 3. Precise positioning and fast deployment of the supporting leg structure: The L-shaped supporting leg is matched with a magnetically adsorbed positioning rod and a foot-treading rubber plate. The magnetic adsorption design keeps the rod in place in the non-treading state, avoiding accidental falling or shaking. The foot-treading rubber plate provides a comfortable force point, allowing the operator to quickly and easily tread the three rods into the ground to complete the stable positioning, especially suitable for complex terrains such as dam slopes.

[0021] 4. Modularized collaborative advancement and stable sampling: Three synchronous servo motor driven advancement mechanisms (threaded rod + lifting block + vertical sliding rod) are evenly distributed on the disc ring. They work synchronously to drive the rotating disc and the entire sampling mechanism to smoothly and vertically insert or exit the soil, ensuring the stability of the sampling cylinder posture and preventing sampling deviation or mechanism jam caused by tilting.

[0022] 5. 60° indexing rotary locking handle: The handle structure integrates double mechanisms of latch locking (latch + latch slot) and spring pre-pressing positioning (round head rod + spring + arc-shaped positioning slot). Each operation only needs to pull up the latch, rotate the handle by 60 degrees (with a "ding" positioning feedback), and then insert the latch to lock. This design intuitively and reliably controls the rotary position of the sampling cylinder (connecting the sampling hole / closing the sampling hole), ensuring the precise alignment and isolation of the three sampling grooves.

[0023] 6. Efficient soil scraping mechanism: The sampling fold edge of the sampling hole is combined with the overall rotation of the sampling cylinder (driven by the gear-ring of the rotary driving mechanism). When the sampling hole is aligned with the sampling groove, the rotating fold edge can efficiently scrape the soil into the sampling groove, improving the sampling efficiency and sample integrity.

[0024] The present application is realized by the cooperation of the rotary sampling cylinder and sampling hole design, the precise 60° indexing rotary locking handle, and the bottom sealing structure of the integrated drill bit, which can collect different depth of soil, avoid mixing of the collected soil, and ensure the stability of the sampling process through three-point synchronous advancement. The magnetic foot-treading positioning rod simplifies the deployment of river embankments. BRIEF DESCRIPTION OF DRAWINGS
