Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rock stratum sampling tools, in particular to a fault gouge sampling tool. Background Art
[0002] Faults are usually structures where the earth's crust breaks under stress, resulting in significant relative displacement of rock blocks on both sides of the fracture surface.
[0003] Active faults generally refer to faults that have been continuously active in the most recent geological period and are expected to remain active in the future. Their existence presents a potential risk of fault-related hazards, particularly unpredictable earthquakes and the associated potential hazards. Active faults can trigger surface ruptures, earthquakes, and the accompanying collapses, landslides, rockfalls, avalanches, barrier lakes, debris flows, soil liquefaction, subsidence, ground fissures, and groundwater changes. They can also cause surface movement and ground subsidence due to slow fault movement (creep). Therefore, investigating active faults and implementing appropriate urban planning can mitigate and avoid the significant potential threats they pose to urban safety. Current investigations of active faults primarily rely on field surveys and sampling and analysis, but sampling is often performed in the Quaternary system or fault gouge using tools such as geological hammers, shovels, and ice picks.
[0004] Existing fault mud sampling mainly uses geological hammers, shovels, ice picks, etc., but fault mud is distributed in the fault, and the fault is often relatively narrow. It is extremely inconvenient to use geological hammers, shovels, etc., and it is inconvenient to knock the rock with an ice pick.
[0005] Therefore, we propose a fault gouge sampling tool to solve the problems in the above background. Utility Model Content
[0006] The purpose of the present utility model is to provide a fault gouge sampling tool to solve the problems raised in the above background technology.
[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:
[0008] A fault gouge sampling tool comprises a sampling head, a handle and an anti-slip cover, wherein the sampling head and the handle are integrally cast and formed by steel material;
[0009] One end of the sampling head is flat, perpendicular to the handle, and has a thickness of about 5 mm, which can be inserted into a narrow fault to take samples;
[0010] The flat end of the sampling head is arc-shaped on the outside and serrated on the inside, which is convenient for crushing rocks in narrow faults;
[0011] The connection between the sampling head and the handle is configured as a truncated cone, and a plurality of reinforcing ribs are fixedly connected between the sampling head and the outside of the handle, and the plurality of reinforcing ribs are evenly distributed around the periphery of the sampling head and the handle.
[0012] Preferably, the other end of the sampling head is square, with a size of about 3 cm×3 cm, and can be used to knock on harder rocks.
[0013] Preferably, the anti-slip sleeve is put on the surface of the handle to prevent it from falling off during use.
[0014] Preferably, during sampling, the flat portion of the sampling head is placed into the fault to collect fault gouge.
[0015] Preferably, if a narrow fault is encountered, the square part of the sampling head can be used to knock on the rock to widen the sampling surface before collecting samples.
[0016] Preferably, the handle is provided with evenly distributed hollow grooves, and the hollow grooves are hexagonal holes.
[0017] Preferably, a lanyard is provided at the end of the handle for easy carrying when taking samples outside.
[0018] Preferably, the anti-slip sleeve is provided with a curved anti-slip outer surface and the surface is provided with anti-slip grooves, and a bolt is installed between the anti-slip sleeve and the handle, and the bolt passes through the interior of the handle.
[0019] Compared with the prior art, the beneficial effects achieved by the present invention are:
[0020] First, the fault mud sampling tool of the present invention has the following beneficial effects: the sampling head and the handle are integrally cast and formed by steel material, which ensures the connection strength, and the steel material makes the tool have higher strength and durability. The flat design of one end of the sampling head enables it to be inserted into narrower faults to collect samples. The outer arc and inner serrated design help to break the rocks in narrow faults and improve sampling efficiency; the square other end can knock harder rocks, which solves the problem of inconvenience and insufficient strength of ice picks knocking rocks, and provides convenience for widening the sampling surface. The frustum-shaped design of the connection between the sampling head and the handle and the setting of reinforcing ribs enhance the stability and strength of the connection. The inside of the handle is provided with evenly distributed hollow grooves, which reduces the weight while maintaining a certain strength, making operation easier; a hanging rope is provided at the end for easy carrying when sampling outside, and the anti-slip sleeve is provided with a curved anti-slip outer surface and anti-slip grooves to further improve the anti-slip effect, and is connected to the handle by bolts, so it is firmly installed and not easy to fall off.
[0021] Second, the sampling tool of the present invention has multiple design features that enable it to adapt to different sampling environments and needs, such as collecting samples in narrow faults, knocking rocks to widen the sampling surface, etc., which improves the applicability and practicality of the sampling tool. The design of the anti-slip sleeve improves safety during use and reduces operational errors and accidental injuries caused by hand slippage. The overall structural design provides users with clear operating instructions to ensure that fault mud can be effectively collected. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0028] See also Figure 1-4 , the utility model provides a technical solution:
[0029] A fault gouge sampling tool comprises a sampling head 1, a handle 2 and an anti-slip sleeve 3. The sampling head 1 and the handle 2 are integrally cast and formed by steel material.
[0030] The integrated casting ensures the connection strength between the sampling head and the handle, and the steel material gives the tool high strength and durability.
[0031] One end of the sampling head 1 is flat and perpendicular to the handle 2. It is about 5mm thick and can be inserted into narrow faults to take samples. The outer side of the flat end of the sampling head 1 is curved and the inner side is provided with serrations, which is convenient for crushing rocks in narrow faults.
[0032] The connection between the sampling head 1 and the handle 2 is set to be a truncated cone shape, and multiple reinforcing ribs 4 are fixedly connected between the sampling head 1 and the outside of the handle 2. The multiple reinforcing ribs 4 are evenly distributed on the periphery of the sampling head 1 and the handle 2.
[0033] The flat design with a thickness of about 5 mm enables it to be inserted into narrow faults to collect samples; the outer arc and inner serrated design help to break the rocks in narrow faults and improve sampling efficiency; the setting of the frustum-shaped connection and the reinforcing rib 4 enhances the stability and strength of the connection between the sampling head and the handle.
[0034] The other end of the sampling head 1 is square, with a size of about 3cm×3cm, which can be used to hit harder rocks. This solves the problem of inconvenience and insufficient strength in hitting rocks with an ice pick, enabling the sampling tool to effectively hit harder rocks, providing convenience for widening the sampling surface.
[0035] The anti-slip cover 3 is put on the surface of the handle 2 to prevent it from falling off during use, thereby improving safety during use and reducing operational errors and accidental injuries caused by hand slippage. When sampling, the flat part of the sampling head 1 is placed into the fault to collect fault mud, providing users with clear operating instructions to ensure that fault mud can be effectively collected. If a narrow fault is encountered, the square part of the sampling head 1 can be used to knock on the rock to widen the sampling surface before collecting samples. This solves the problem of narrow faults that are difficult to sample, and improves the applicability and practicality of the sampling tool.
[0036] The handle 2 is provided with evenly distributed hollow grooves 5 inside. The hollow grooves 5 are hexagonal holes, which reduce the weight of the handle while maintaining a certain strength, making it easier for the user to operate. A hanging rope 6 is provided at the end of the handle 2, which is convenient for carrying when taking samples outside and facilitates the carrying of sampling tools, especially when taking samples outside, so that the user can carry and use it at any time.
[0037] The anti-slip cover 3 is provided with a curved anti-slip outer surface and anti-slip grooves on the surface. A bolt 7 is installed between the anti-slip cover 3 and the handle 2, and the bolt 7 passes through the interior of the handle 2.
[0038] The anti-slip effect is further improved, ensuring that the user can hold the handle firmly during operation; the connection method of the bolt 7 enables the anti-slip sleeve to be more firmly installed on the handle and is not easy to fall off.
[0039] Although specific embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit thereof, and that the scope of the present invention is defined by the appended claims and their equivalents.
