Description

Technical Field

[0001] This utility model relates to the field of rock core storage technology, specifically a PVC pipe receiving device for rock cores. Background Technology

[0002] Drilling is one of the most widely used exploration methods in geological exploration. Its purpose is to obtain rock cores, mineral samples, soil samples, etc. from different depths for analysis and research, in order to determine the physical and mechanical properties of rocks and soil layers. It is an important means of understanding geological structure or geological formation and can provide the necessary information for exploration and excavation.

[0003] Rock cores are columnar rock specimens obtained from strata using tubular instruments during geological exploration. Currently, both domestically and internationally, there is increasing emphasis on the protection of geological data (rock cores).

[0004] A search revealed that Chinese Patent Publication No. CN 212958531 U discloses a novel core collection bucket, relating to the field of drilling and exploration technology. The bucket includes a core cylinder and a curved collection component located inside the core cylinder. An outlet is located on the bottom side of the core cylinder, and an outwardly extending collection device is provided at the outlet. The collection device is detachably connected to the core cylinder and includes a PVC pipe. The bottom of the curved collection component communicates with the PVC pipe, and the curved collection component and the PVC pipe form a smooth, curved track, facilitating the orderly sliding of the core from the core cylinder. This invention avoids disordered core collection, preventing core damage, and enables accurate geological analysis. Furthermore, this invention has a simple structure, is economical and practical, and offers significant economic benefits.

[0005] The core collection device in the aforementioned patent still has certain shortcomings. Although the patent uses PVC pipes, they together with the core cylinder and curved receiving component form a core collection bucket to collect the cores. However, it is difficult to directly receive the cores pushed out of the core tube using a hydraulic system. This still results in the cores being exposed to air for a long time during the transfer process, causing oxidation and affecting the quality of the cores. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a PVC pipe receiving device for rock cores. This solves the problem that while PVC pipes are used, they, along with the rock core cylinder and curved receiving component, form a rock core receiving bucket for collecting rock cores. However, this device is not suitable for directly receiving rock cores pushed out of the rock core pipe using a hydraulic system. This results in the rock cores being exposed to air for extended periods during transfer, causing oxidation and affecting the quality of the rock cores.

[0007] This utility model provides the following technical solution: a PVC pipe receiving device for rock cores, including a PVC storage pipe, one end of which is provided with a receiving and fixing component, the other end of which is provided with a stabilizing and pushing component, a sealing component on the PVC storage pipe, and a rock core drill rod inserted into the end of the PVC storage pipe.

[0008] The receiving and fixing assembly includes two arc-shaped clamping plates symmetrically arranged at the end of the PVC storage pipe. The arc-shaped clamping plates are both clamped at the end of the core drill rod. Two side connecting plates are symmetrically arranged on both sides of the arc-shaped clamping plates. Two fixing holes are symmetrically opened on the side connecting plates. Fixing screws are inserted through the fixing holes. Fixing nuts are fitted at the ends of the fixing screws.

[0009] The sealing assembly includes a top side insertion hole opened on the top side of the end of the PVC storage pipe, a sealing connecting plate fixed on the top side insertion hole, a sealing movable groove opened at the bottom end of the sealing connecting plate, a sealing baffle provided in the sealing movable groove, a fixing connecting block fixed at the top end of the sealing baffle, and a driving screw hole opened at the top end of the sealing connecting plate.

[0010] Preferred technical solution 1: A drive screw is rotatably connected to the fixed connecting block, and the top end of the drive screw passes through the drive screw hole.

[0011] Preferred technical solution 2: The stable pushing component includes a fixing cap fixed to the end of the PVC storage pipe, a core push rod is threaded into the side of the fixing cap, and a limit push plate is rotatably connected to the end of the core push rod.

[0012] Preferred technical solution 3: The top end of the drive screw is provided with a connecting block that facilitates rotation.

[0013] This solution makes it easier for users to rotate the drive screw.

[0014] Preferred technical solution four: The diameter of the sealing baffle is the same as the inner diameter of the PVC storage pipe.

[0015] This solution enables the sealing baffle to close the end of the PVC storage pipe.

[0016] Preferred technical solution five: The diameter of the limiting push plate is the same as the inner diameter of the PVC storage pipe.

[0017] This solution enables the limiting push plate to better limit the movement of the rock core transferred into the PVC storage pipe.

[0018] Compared with the prior art, this utility model provides a PVC pipe receiving device for rock cores, which has the following beneficial effects:

[0019] (1) This utility model provides a receiving and fixing component, a sealing component, and a stabilizing and pushing component on a PVC storage pipe. The arc-shaped clamping plate in the receiving and fixing component is fixed to the end of the core drill rod under the fixing screw, thus connecting the core drill rod to the PVC storage pipe. The end of the core pushed into the PVC storage pipe can be sealed by inserting a sealing baffle into the PVC storage pipe. The limiting push plate in the stabilizing and pushing component is fixed in the PVC storage pipe by the core push rod and the sealing baffle, ensuring that the core is more stable in the PVC storage pipe. This receiving process effectively avoids the problem of core oxidation from contact with air and avoids the problem of core contamination or moisture loss, greatly improving the quality of core sampling.

[0028] Please see Figure 1-4 ,

[0029] Example 1: A PVC pipe receiving device for rock cores includes a PVC storage pipe 1, a receiving and fixing component 2 is provided at one end of the PVC storage pipe 1, a stabilizing and pushing component 4 is provided at the other end of the PVC storage pipe 1, a sealing component 3 is provided on the PVC storage pipe 1, and a rock core drill rod 5 is inserted into the end of the PVC storage pipe 1.

[0030] The receiving and fixing component 2 includes two arc-shaped clamping plates 201 symmetrically arranged at the end of the PVC storage pipe 1. The arc-shaped clamping plates 201 are both clamped at the end of the core drill rod 5. Two side connecting plates 202 are symmetrically arranged on both sides of the arc-shaped clamping plates 201. Two fixing holes 203 are symmetrically opened on the side connecting plates 202. Fixing screws 204 are inserted through the fixing holes 203. Fixing nuts 205 are sleeved on the ends of the fixing screws 204.

[0031] The sealing assembly 3 includes a top side insertion hole 301 opened on the top side of the end of the PVC storage pipe 1. A sealing connecting plate 302 is fixed on the top side insertion hole 301. A sealing movable groove 303 is opened at the bottom end of the sealing connecting plate 302. A sealing baffle 304 is provided in the sealing movable groove 303. A fixing connecting block 305 is fixed at the top end of the sealing baffle 304. A driving screw hole 306 is opened at the top end of the sealing connecting plate 302. A driving screw 307 is rotatably connected to the fixing connecting block 305. The top end of the driving screw 307 passes through the driving screw hole 306.

[0032] The stabilizing push assembly 4 includes a fixing cap 401 fixed to the end of the PVC storage pipe 1. A core push rod 402 is threaded into the side of the fixing cap 401, and the end of the core push rod 402 is rotatably connected to a limit push plate 403.

[0033] Example 2: The difference between this example and Example 1 is that the top end of the drive screw 307 is provided with a connecting block that facilitates rotation.

[0034] This makes it more convenient for users to rotate the drive screw 307.

[0035] Example 3: The difference between this example and Example 1 is that the diameter of the sealing baffle 304 is the same as the inner diameter of the PVC storage pipe 1.

[0036] This allows the sealing baffle 304 to close the end of the PVC storage pipe 1.

[0037] Example 4: The difference between this example and Example 1 is that the diameter of the limiting push plate 403 is the same as the inner diameter of the PVC storage tube 1.

[0038] This allows the limiting push plate 403 to better limit the movement of the rock core transferred to the PVC storage pipe 1.

[0039] In this embodiment, although the existing receiving pipe uses PVC pipe, it together with the core tube and curved receiving component to form a core receiving bucket for collecting cores. However, it is difficult to directly receive the cores when the cores are pushed out of the core tube using a hydraulic system. This will still cause the cores to be exposed to the air for a long time during the transfer process, resulting in oxidation and affecting the quality of the cores.

[0040] In summary, during implementation, after the user retrieves core samples from the ground using a drilling rig and core drill rod 5, the user needs to attach the end of the PVC storage pipe 1 to the end of the core drill rod 5. The two arc-shaped clamping plates 201 in the receiving and fixing assembly 2 are then secured to both sides of the end of the core drill rod 5. Fixing screws 204 are inserted into the side connecting plates 202, and fixing nuts 205 are used to tighten the two side connecting plates 202 together. This ensures that the arc-shaped clamping plates 201 are securely attached to the end of the core drill rod 5, achieving a tight connection between the PVC storage pipe 1 and the core drill rod 5.

[0041] Next, the core drill rod 5 is pushed from its end to the PVC storage tube 1 by a hydraulic system. The other end of the PVC storage tube 1 is tightly closed by a stabilizing push assembly 4. After the core enters the inner wall of the PVC storage tube 1, the user rotates the drive screw 307 inserted in the drive screw hole 306 at the top of the sealing connection plate 302. This causes the drive screw 307 to push the sealing baffle 304 toward the top insertion hole 301, so that the sealing baffle 304 is fully inserted into the end of the PVC storage tube 1 and closes it, thereby sealing and preserving the core that has entered the PVC storage tube 1.

[0042] Finally, the user needs to rotate the core pusher 402 in the stabilizing push assembly 4, thereby pushing the fixed cover 401 rotatably connected to the end of the core pusher 402. This allows the fixed cover 401 to come into contact with the end of the core pushed into the PVC storage tube 1. Under the combined contact of the fixed cover 401 and the sealing baffle 304, the core is stored more stably in the PVC storage tube 1, effectively preventing the core from loosening due to shaking during the transfer of the PVC storage tube 1. This device can directly push the core from the core drill rod 5 into the PVC storage tube 1, thereby avoiding the core from contacting air for oxidation, as well as contamination or moisture loss, greatly improving the quality of core sampling.
