Description

Technical Field

[0001] This utility model relates to the field of soil and rock sampling equipment technology, specifically, to a soil and rock sampling equipment used in water conservancy construction. Background Technology

[0002] Soil and rock sampling equipment is a key piece of equipment in fields such as water conservancy, geological exploration, and construction. It is mainly used to obtain soil and rock samples from underground, providing direct physical evidence for stratigraphic analysis, engineering design (such as foundation treatment and slope protection), and disaster assessment (such as landslide early warning). Soil and rock sampling equipment can be classified into manual, electric, hydraulic, and pneumatic types according to their driving method. Among them, manual soil and rock sampling equipment has advantages such as portability, easy assembly and disassembly, no power supply dependence, and low cost. Furthermore, the sampling depth can be gradually increased by splicing extension rods. However, as the sampling depth gradually increases, the weight of multiple extension rods plus the sampling tube also increases simultaneously. At this point, multiple people are required to complete the subsequent sampling work, making single-person deep sampling impossible. Therefore, this utility model designs a soil and rock sampling device for water conservancy construction processes. Utility Model Content

[0003] This utility model proposes a soil and rock sampling equipment for water conservancy construction, which solves the problem in related technologies that when the sampling depth gradually increases, the weight of multiple extension rods plus the sampling tube will also increase simultaneously. At this time, multiple people are needed to complete the subsequent sampling work, and it is impossible to achieve single-person deep sampling.

[0004] The technical solution of this utility model is as follows: A soil and rock sampling device in the process of water conservancy construction includes multiple longitudinally distributed extension rods, the ends of which are connected by threads in sequence. The bottom end of the lowest extension rod is threaded with a sampling cylinder. A fixed platform is slidably sleeved on the outer wall of one of the extension rods. Four mounting sleeves arranged in a circular array are fixedly connected to the bottom of the fixed platform. The bottom end of the mounting sleeves is threaded with a support foot. A clamping mechanism is provided on one side of the fixed platform. A stamping mechanism is slidably sleeved on the outer wall of the extension rod, and the stamping mechanism is located above the fixed platform.

[0005] Preferably, the outer side wall of the extension rod is provided with anti-slip stripes.

[0006] Preferably, the bottom end of the support leg is conical.

[0007] Preferably, the clamping mechanism includes two symmetrically distributed mounting plates, both of which are fixedly connected to one side of the fixed platform. A rotating shaft is rotatably connected to the side of the two mounting plates that are close to each other. A teardrop-shaped tightening block is fixedly sleeved on the outer wall of the rotating shaft. A tightening handle is fixedly connected to the side of the teardrop-shaped tightening block that is away from the fixed platform. A clamping rod is slidably inserted through one side of the fixed platform. The clamping rod is located between the two mounting plates. A reset plate is fixedly sleeved on the outer wall of the clamping rod. Two symmetrically arranged reset springs are fixedly connected to the side of the reset plate that is close to the fixed platform. The end of the reset spring that is away from the reset plate abuts against one side of the fixed platform.

[0008] Preferably, the return spring is in a compressed state, and the end of the clamping rod near the teardrop-shaped tightening block is hemispherical and abuts against the teardrop-shaped tightening block.

[0009] Preferably, the stamping mechanism includes a stamping sleeve, which is slidably sleeved on the outer wall of the extension rod. A force-bearing ring and a limiting ring are fixedly sleeved on the outer wall of the stamping sleeve, with the limiting ring located above the force-bearing ring. A stamping block is slidably sleeved on the outer wall of the stamping sleeve, and the stamping block abuts against the upper surface of the force-bearing ring. The upper surface of the stamping block has several counterweight holes arranged in a circular array. A counterweight insert is slidably inserted into the counterweight holes, and a counterweight block is fixedly connected to the top end of the counterweight insert. Two symmetrically arranged tightening threaded rods are threaded into the outer wall of the stamping sleeve, with one end of the tightening threaded rod located inside the stamping sleeve abutting against the outer wall of the extension rod.

[0010] Preferably, the outer wall of the counterweight rod is provided with an anti-slip rubber layer.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. Breaks through the limitations of single-person deep sampling, significantly reducing labor costs.

[0013] This utility model solves the pain points of traditional manual equipment for deep sampling, namely, the large weight of the extension rod and sampling cylinder when stacked together, requiring multiple people to lift / coordinate force, through the coordinated design of "fixed platform + clamping mechanism + stamping mechanism". The fixed platform is stably supported on the ground by the support legs, the clamping mechanism can firmly lock the extension rod (preventing the rod from shaking or sinking), and the stamping mechanism provides impact power with the gravitational potential energy of the counterweight (without the need for continuous manual force). Only one person is needed to complete the entire process of "lifting the stamping block - releasing the impact - adjusting the depth", without the need for multiple people to coordinate, which significantly reduces manpower input and reduces labor costs and management difficulty in water conservancy construction.

[0014] 2. Adaptable to soils of varying hardness and depth requirements, improving sampling efficiency and flexibility.

[0015] Firstly, the counterweight of the stamping mechanism can be flexibly adjusted by "increasing or decreasing the number of counterweight rods" to adjust the impact force (e.g., reducing the counterweight in soft soil areas to avoid excessive sample compaction, and increasing the counterweight in hard soil / clay layers to improve soil penetration efficiency), adapting to the soil hardness of different strata in water conservancy construction (from sand to dense clay). Secondly, the extension rod adopts a threaded connection design at both ends, which can be flexibly spliced ​​according to the sampling depth requirements (e.g., shallow exploration of dams, deep sampling at the bottom of river channels). Combined with the sliding adjustment characteristics of the stamping mechanism, the sampling depth range is significantly greater than that of traditional manual equipment, and there is no need to frequently replace the entire set of equipment, thus improving sampling efficiency. At the same time, the stamping power replaces manual hammering / pressing, and the soil penetration depth of a single impact is more uniform, greatly shortening the operation time for deep sampling.

[0016] 3. Simple structure and easy operation, suitable for complex water conservancy construction scenarios.

[0017] The core components of this utility model (extension rod, fixed platform, and stamping mechanism) all adopt a "modular design + threaded connection / sliding sleeve" for easy assembly and disassembly (such as quick splicing of the extension rod and plug-and-play installation of the counterweight), making it easy to transport to remote areas of water conservancy construction (such as mountain rivers and reservoir banks). In addition, the height of the fixed platform's legs can be adjusted by the threaded installation sleeve, which can adapt to uneven sites commonly found in water conservancy scenarios (such as slopes and gravel areas), eliminating the need for additional auxiliary support structures, reducing the difficulty of on-site setup, and improving the equipment's adaptability to complex environments.

[0018] 4. Enhance operational safety and reduce construction risks.

[0019] The anti-slip rubber layer on the outside of the counterweight rod prevents the counterweight from falling off during operation; the limiting ring of the stamping mechanism limits the maximum lifting height of the stamping block, preventing the counterweight from falling accidentally due to excessive lifting; at the same time, the stable support of the fixed platform and the locking function of the clamping mechanism reduce safety hazards such as equipment tipping and rod rebound, especially in water conservancy construction scenarios such as sampling near water or at height (such as dam slopes), which can effectively protect the personal safety of operators.

[0031] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0032] Example

[0033] like Figures 1-4 As shown in the figure, this embodiment proposes a soil and rock sampling equipment for water conservancy construction, including multiple longitudinally distributed extension rods 1, which are connected end to end by threads. The bottom end of the lowest extension rod 1 is threadedly connected to a sampling cylinder 2. A fixed platform 3 is slidably sleeved on the outer wall of one of the extension rods 1. Four mounting sleeves 4 arranged in a circular array are fixedly connected to the bottom of the fixed platform 3. The bottom end of the mounting sleeves 4 is threadedly connected to a support leg 41. A clamping mechanism 5 is provided on one side of the fixed platform 3. A stamping mechanism 6 is slidably sleeved on the outer wall of the extension rod 1, and the stamping mechanism 6 is located above the fixed platform 3.

[0034] The extension rod 1 has anti-slip stripes on its outer side wall, which can increase the friction between the extension rod 1 and the clamping rod 55.

[0035] The bottom end of the support leg 41 is conical, and the conical bottom end of the support leg 41 can be inserted into the ground to prevent the device from shifting or tipping over during use.

[0036] The clamping mechanism 5 includes two symmetrically distributed mounting plates 51, both of which are fixedly connected to one side of the fixed platform 3. A rotating shaft 52 is rotatably connected to the side of the two mounting plates 51 that is close to each other. A teardrop-shaped tightening block 53 is fixedly sleeved on the outer wall of the rotating shaft 52. A tightening handle 54 is fixedly connected to the side of the teardrop-shaped tightening block 53 that is away from the fixed platform 3. A clamping rod 55 is slidably inserted through one side of the fixed platform 3. The clamping rod 55 is located between the two mounting plates 51. A reset plate 56 is fixedly sleeved on the outer wall of the clamping rod 55. Two symmetrically arranged reset springs 57 are fixedly connected to the side of the reset plate 56 that is close to the fixed platform 3. The end of the reset spring 57 that is away from the reset plate 56 abuts against one side of the fixed platform 3. When sampling deep soil, the clamping mechanism 5 can temporarily fix the extension rod 1 before the sampling cylinder 2 touches the bottom, which is convenient for loosely connecting the extension rod 1.

[0037] The return spring 57 is in a compressed state, and the end of the clamping rod 55 near the teardrop-shaped tightening block 53 is hemispherical and abuts against the teardrop-shaped tightening block 53. The return spring 57 in the compressed state can provide kinetic energy for the return of the clamping rod 55.

[0038] The stamping mechanism 6 includes a stamping sleeve 61, which is slidably sleeved on the outer wall of the extension rod 1. A force-bearing ring 62 and a limiting ring 63 are fixedly sleeved on the outer wall of the stamping sleeve 61. The limiting ring 63 is located above the force-bearing ring 62. A stamping block 64 is slidably sleeved on the outer wall of the stamping sleeve 61. The stamping block 64 abuts against the upper surface of the force-bearing ring 62. The upper surface of the stamping block 64 has several counterweight holes 65 arranged in a circular array. A counterweight rod 66 is slidably inserted into the counterweight hole 65. A counterweight block 67 is fixedly connected to the top end of the counterweight rod 66. Two symmetrically arranged screw-in threaded rods 68 are threaded into the outer wall of the stamping sleeve 61. One end of the screw-in threaded rod 68 located inside the stamping sleeve 61 abuts against the outer wall of the extension rod 1. The stamping mechanism 6 can provide impact force to the sampling cylinder 2 during sampling.

[0039] The outer wall of the counterweight insertion rod 66 is provided with an anti-slip rubber layer, which can prevent the counterweight from falling off during operation.

[0040] Specifically, when using this device for deep soil sampling, the upper soil layer needs to be gradually removed through the sampling tube 2 to form a hole that penetrates deep into the soil layer. As the sampling depth gradually increases, the weight of the multiple extension rods 1 and the sampling tube 2 will also increase simultaneously. At this time, the operation of continuing the extension rod 1 is as follows: the tightening handle 54 needs to be rotated to drive the teardrop-shaped tightening block 53 to rotate around the rotating shaft 52, thereby pushing the clamping rod 55 to slide inward to the fixed platform 3. The clamping rod 55 locks the extension rod 1 to prevent the rod from sinking. In this state, the extension rod 1 can be easily continued. After the continuation is completed, the tightening handle 54 is rotated in the opposite direction to release the lock on the extension rod 1, and the sampling tube 2 is continued to be conveyed downward, and the above continuation and locking process is repeated. When the sampling cylinder 2 reaches the preset sampling depth (or touches the target soil layer), the stamping sleeve 61 is slidably fitted onto the uppermost extension rod 1, and the threaded rod 68 is rotated and tightened to fix the stamping sleeve 61 and the extension rod 1 relative to each other; then the stamping block 64 is lifted upwards and then released, using the gravitational potential energy of the stamping block 64 to provide impact force for the sampling cylinder 2 to press into the soil layer. The counterweight 67 can be set to adjust the magnitude of the impact force generated when the stamping block 64 falls according to the softness or hardness of the soil, so as to achieve flexible adaptation of the impact force.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
