Description

Technical Field

[0001] This utility model belongs to the field of hydrogeological survey technology, and in particular relates to a drilling device for hydrogeological surveys. Background Technology

[0002] Hydrogeological surveys are investigations and studies of the formation, distribution, movement, quality, and quantity of groundwater. Through geological mapping, geophysical exploration, drilling, sampling and analysis, they determine the regional hydrogeological conditions, providing a basis for water resource development and utilization, engineering construction, and environmental protection. They are the foundation of hydrogeological work. Drilling equipment is crucial in hydrogeological surveys; it can penetrate the surface to obtain underground rock cores and soil samples, directly revealing the location, thickness, and lithology of aquifers. Piezometers can be installed in the boreholes to monitor water levels, collect water samples for analysis, and conduct pumping tests to determine hydrological parameters. This provides key data for accurately understanding the state and movement patterns of groundwater, making it a core tool for obtaining accurate underground information.

[0003] The drilling equipment commonly used in hydrogeological surveys is often a spiral drilling machine. When drilling into the ground, the loose sand and soil inside the hole will splash out as the spiral drill bit rotates, causing a large amount of loose sand and soil to accumulate around the hole. After drilling is completed, these loose deposits are very likely to fall into the hole, causing the bottom of the hole to be blocked, increasing the error of the survey data, and affecting the reliability of hydrogeological condition analysis.

[0066] The above solution is adopted: the fixed shell 8 mainly serves to provide support and protection for the sliding component 7, the stroke component 6 and the springback component 10.

[0067] refer to Figure 2 As shown, a pressing component 9 is provided on the surface of the fixed shell 8. There are two pressing components 9, and the two pressing components 9 include:

[0068] Press plate 91: The side of the press plate 91 closest to the stroke block 62 is fixedly connected to the outer surface of the stroke block 62;

[0069] Third slide groove 92: The third slide groove 92 is opened on the outer surface of the fixed shell 8, and the inner wall of the third slide groove 92 is slidably connected to the outer surface of the pressing plate 91.

[0070] Fourth slide groove 93: The fourth slide groove 93 is formed on the outer surface of the dust cover 41, and the inner wall of the fourth slide groove 93 is slidably connected to the outer surface of the pressing plate 91.

[0071] Using the above scheme: In order to move the travel block 62 downward, the pressing plate 91 is pressed down, and the pressing plate 91 can move downward along the inner wall of the third slide groove 92, and the pressing plate 91 can drive the travel block 62 to move downward.

[0072] refer to Figure 3 As shown, a spring-loaded assembly 10 is provided on the lower side of the pressing plate 91. There are two spring-loaded assemblies 10, and the two spring-loaded assemblies 10 include:

[0073] Sliding column 101: The outer surface of the sliding column 101 is slidably connected to the inner wall of the pressing plate 91. The upper end face of the sliding column 101 is fixedly connected to the inner wall of the fixed shell 8, and the lower end face of the sliding column 101 is fixedly connected to the upper surface of the drilling mechanism 3.

[0074] Spring 102: Spring 102 is sleeved on the outer surface of sliding column 101. The upper end face of spring 102 is fixedly connected to the lower surface of pressing plate 91, and the lower end face of spring 102 is fixedly connected to the upper surface of drilling mechanism 3.

[0075] Using the above scheme: when the pressing plate 91 moves downward, the pressing plate 91 can move downward along the sliding column 101, and the pressing plate 91 can squeeze the spring 102, so that the spring 102 generates elastic force.

[0076] The working principle of this utility model:

[0077] In use, after moving the device to the designated position, the hydraulic mechanism 2 and the drilling mechanism 3 are activated to begin drilling the ground. After drilling is complete, pressing down on the pressing plate 91 causes it to move downwards along the inner wall of the third slide groove 92 and the outer surface of the sliding column 101. The pressing plate 91 compresses the spring 102, causing it to generate elastic force. Simultaneously, the pressing plate 91 drives the stroke block 62 to move downwards. The stroke block 62 can move downwards along the sliding rod 72 via the sliding plate 71. At the same time, the stroke block 62 can compress the stroke column 61 via the stroke groove 63 on its surface, causing the stroke column 61 to move downwards along the stroke groove. The inner wall of 63 slides, and the stroke column 61 can drive the connecting rod 53 to slide outward, moving outward along the inner wall of the second slide groove 54. The connecting rod 53 can drive the telescopic rod 51 through the support plate 52, so that the telescopic rod 51 drives the push plate 43 to move outward along the inner wall of the first slide groove 42. The push plate 43 pushes out the loose sand and gravel soil on the outside to prevent the loose sand and gravel soil from falling back into the drilled hole. Then, stop pressing the pressing plate 91, the spring 102 releases its elastic force, and pushes the pressing plate 91 to move back. Finally, the drilling mechanism 3 can be moved back through the hydraulic mechanism 2 to complete the drilling process.

[0078] In summary, this drilling device for hydrogeological surveys, through its cleaning component 4, connecting component 5, travel component 6, sliding component 7, fixing shell 8, pressing component 9, and rebound component 10, solves the problem that during drilling, a large amount of loose sand and gravel soil is generated. After drilling, these loose deposits easily fall into the hole, causing blockage at the bottom of the hole, increasing the error of the survey data, and affecting the reliability of hydrogeological condition analysis.
