Description

Technical Field

[0001] This utility model relates to the field of geological exploration technology, and in particular to a geological exploration safety protection device. Background Technology

[0002] Geological exploration refers to the systematic and comprehensive investigation, research and evaluation of the geological structure, lithology, strata, and mineral resources of the Earth's surface and underground. Its purpose is to explore and assess the geological structure, stratigraphic composition, mineral resource distribution, hydrogeological conditions, and other aspects of the Earth's interior and surface.

[0003] A search revealed that patent CN221959779U discloses a safety protection device for geological exploration.

[0004] However, the above technical solution has the following problems: after protecting the geological layers such as gravel and soil with protective shovels, it is still necessary to put hands into the hole to take samples. When there are harmful substances in the exploration area, it is easy to cause harm to the sampling personnel. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where, after protecting geological layers such as gravel and soil with a protective shovel, it is still necessary to reach into the hole to take samples. If there are harmful substances in the exploration area, this can easily cause injury to the sampling personnel. Therefore, this invention proposes a geological exploration safety protection device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A geological exploration safety protection device includes a connecting rod and a sampling tube. The connecting rod is positioned above the sampling tube, and two rotating grooves are formed on the outer side of the connecting rod. The bottom of the sampling tube is set as an open part, and a circular hole is formed on the top of the sampling tube.

[0008] A telescopic mechanism is installed on the sampling cylinder to facilitate adjustment of the device's length.

[0009] A rotating mechanism is installed on the device for sampling the sample.

[0010] In one possible design, the telescopic mechanism includes an outer cylinder, two locking blocks, an inner rod, a side hole, and a fixing post. The top of the outer cylinder is fixedly connected to the bottom end of the connecting rod. Two locking slots adapted to the locking blocks are opened on the inner wall of the outer cylinder. The two locking blocks are slidably connected to the two locking slots respectively. Both locking blocks are fixedly connected to the outer side of the same inner rod. The outer side of the bottom end of the inner rod is rotatably connected to the inner wall of the circular hole. The side hole is set on the outer cylinder. Multiple side grooves adapted to the side hole are opened on the outer side of the inner rod. One end of the fixing post is threaded through the side hole and threadedly connected to the side groove. A rotating handle is fixedly connected to one end of the fixing post.

[0011] In one possible design, the rotating mechanism includes a rotating rod, a spiral blade, and a conical nail. The top end of the rotating rod is fixedly connected to the bottom end of the inner rod, the bottom end of the rotating rod is fixedly connected to the top of the conical nail, and the spiral blade is fixedly sleeved on the outside of the rotating rod and located inside the sampling cylinder.

[0012] In one possible design, the bottom of the sampling tube is fixedly connected to a conical ring that facilitates insertion into a plane.

[0013] In one possible design, the outer side of the connecting rod is rotatably connected to a gripping ring that facilitates vertical gripping of the device. Two rotating rings are fixedly connected to the inner wall of the gripping ring, and the two rotating rings are engaged with and slidably connected to two rotating grooves.

[0014] In one possible design, a gripping ring is fixedly connected to the top of the connecting rod to facilitate holding and rotating the device, and an anti-slip sleeve is provided on the outer side of the gripping ring.

[0015] In this application, during use, the fixing post is first loosened by rotating the handle, causing it to disengage from the current side groove. Then, the user can slide the inner rod up and down to adjust the overall length of the device. When the inner rod slides to the desired position, the user rotates the handle again, causing the fixing post to thread into the corresponding side groove, thus fixing the position of the inner rod. When the user needs to take a sample, the entire device can be rotated using the grip ring, and the grip ring provides a convenient point of contact for picking up and rotating the entire device. The anti-slip sleeve design increases stability and comfort during gripping. This reduces the risk of accidental slippage. By gripping the holding ring, the rotating ring inside engages with the rotating groove on the connecting rod, ensuring the stability and verticality of the device during rotation. This rotational motion is transmitted to the rotating rod, which in turn drives the cone and the spiral blade to rotate. The cone first inserts into the geological layer; the cone ring design makes it easier to insert the sampling tube into the geological layer, improving sampling stability and accuracy. Subsequently, the rotation of the spiral blade carries the geological sample upwards into the sampling tube. After sampling, the device can be pulled out. By changing the direction of rotation, the spiral blade can also pour the sample out of the sampling tube.

[0016] The beneficial effects of this utility model are as follows:

[0017] In this invention, the telescopic mechanism allows the device to be length-adjusted according to different geological exploration needs, improving the applicability and flexibility of the device. The spiral blade design in the rotating mechanism allows geological samples to be efficiently carried upward into the sampling tube, improving sampling efficiency, reducing the danger of manual sampling, and ensuring the safety of staff.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1

[0025] Reference Figures 1-4 A protective device includes a connecting rod 3, a sampling cylinder 5, a telescopic mechanism, and a rotating mechanism. The connecting rod 3 is positioned above the sampling cylinder 5 and serves to connect and support the entire device. The bottom of the sampling cylinder 5 is open for easy sampling, while the top has a circular hole for mounting components of the rotating and telescopic mechanisms.

[0026] The telescopic mechanism is used to adjust the overall length of the device to adapt to geological exploration needs at different depths. Specifically, it includes an outer cylinder 4, two locking blocks 8, an inner rod 7, a side hole 12, a fixing post 13, and a rotating handle. The top of the outer cylinder 4 is fixedly connected to the bottom end of the connecting rod 3, forming a stable support structure. Two locking grooves adapted to the locking blocks 8 are provided on the inner wall of the outer cylinder 4 to restrict the sliding of the inner rod 7. The two locking blocks 8 are slidably connected to the two locking grooves respectively, and both are fixedly connected to the outer side of the same inner rod 7. The outer side of the bottom end of the inner rod 7 is rotatably connected to the inner wall of the circular hole at the top of the sampling cylinder 5, allowing the inner rod 7 to rotate freely within the circular hole. The side hole 12 is provided on the outer cylinder 4 for installing the fixing post 13. Multiple side grooves adapted to the side holes 12 are provided on the outer side of the inner rod 7. When the inner rod 7 slides to a suitable position, it can be fixed inside the outer cylinder 4 by the fixing post 13. One end of the fixing post 13 is threaded through the side hole 12 and threadedly connected to the side groove to fix the position of the inner rod 7. The other end of the fixing post 13 is fixedly connected to a rotating handle, which allows the user to rotate the fixing post 13 to perform fixing or unlocking operations.

[0027] The rotating mechanism is used for sample collection and specifically includes a rotating rod 9, a spiral blade 10, and a conical nail 11. The top end of the rotating rod 9 is fixedly connected to the bottom end of the inner rod 7, forming an integral structure. The bottom end of the rotating rod 9 is fixedly connected to the top end of the conical nail 11, which is used to insert into the geological layer during sampling. The spiral blade 10 is fixedly sleeved on the outside of the rotating rod 9 and located inside the sampling cylinder 5. When the rotating rod 9 rotates, the spiral blade 10 rotates accordingly and carries the geological sample upward out of the sampling cylinder 5. Due to the special shape of the spiral blade 10, reversing the rotation pours the sample out of the sampling cylinder 5.

[0028] This application can be used in the field of geological exploration, or in other fields applicable to this application.

[0029] Example 2

[0030] refer to Figures 1-4 Based on Embodiment 1, an improved geological exploration safety protection device includes:

[0031] A conical ring 6 is fixedly connected to the bottom of the sampling cylinder 5 for easy insertion into a plane. The design of the conical ring 6 makes it easy for the sampling cylinder 5 to be inserted into the geological layer, thereby facilitating sample collection.

[0032] A gripping ring 2 is rotatably connected to the outer side of the connecting rod 3, facilitating vertical gripping of the device. Two rotating rings 14 are fixedly connected to the inner wall of the gripping ring 2, and these two rotating rings 14 engage with and slide through two rotating grooves on the outer side of the connecting rod 3. This design allows the user to stably grip and rotate the entire device vertically, making it easy to maintain the device's vertical position by using the gripping ring 2 when rotating the device for sampling.

[0033] A gripping ring 1 is fixedly connected to the top of the connecting rod 3 to facilitate holding and rotating the device. The outer side of the gripping ring 1 is provided with an anti-slip sleeve to increase the stability and comfort of the user's grip.
