Description

Technical Field

[0001] This invention relates to the field of mud drilling technology, and in particular to a convenient drilling mud preparation and storage device suitable for complex terrain. Background Technology

[0002] Mineral resource exploration is an important foundation for ensuring resource supply. As mineral resource exploration in low-altitude, non-mountainous, and other easily explored areas gradually improves, mineral resources (especially rare metal resources) in complex terrain areas such as high-altitude plateaus and steep mountainous areas have become the focus of current exploration work.

[0003] However, mineral resource exploration in complex terrain areas faces two major challenges: First, the terrain is rugged and transportation is inconvenient. Traditional drilling equipment is large and heavy, requiring additional road construction during transportation, which is not only costly and inefficient, but also makes it difficult for heavy auxiliary equipment such as excavators to reach the construction site, severely restricting the progress of exploration work. Second, ecological and environmental protection requirements are becoming increasingly stringent. Ecosystems in complex terrain areas (such as plateaus and mountains) are fragile. The traditional method of digging and building mud pits is prone to mud leakage and diffusion, causing soil and water pollution, which does not meet the green exploration requirement of "no mud landing". Existing steel mud boxes also have the problems of large size, heavy weight, and high transportation difficulty, and cause significant damage to the surrounding vegetation and terrain during transportation, making it difficult to balance exploration efficiency and ecological protection.

[0004] Drilling mud, the "lifeblood" of drilling operations, is crucial for ensuring its smooth progress through preparation and storage. Given the unique challenges of exploring complex terrain, a mud treatment system is urgently needed that meets the following requirements: Firstly, the equipment must be lightweight and modular, adaptable to convenient transportation methods such as drone hoisting, eliminating the need for heavy transport equipment and road paving, thus reducing transportation difficulties in complex terrain. Secondly, it must achieve closed-loop preparation and storage of the mud, strictly adhering to the "no mud spillage" requirement to prevent ecological pollution.

[0005] Based on the actual needs of exploration in complex terrain, this invention is an important part of drilling technology for complex geographical environments such as plateaus. It specifically addresses the problems of inconvenient transportation of existing equipment and high risk of ecological pollution, and provides a reliable mud treatment solution for mineral resource exploration in complex terrain. Summary of the Invention

[0006] The purpose of this invention is to provide a convenient drilling mud preparation and storage device suitable for complex terrain, which realizes the recycling of resources, reduces energy consumption and costs, effectively reduces environmental pollutant emissions, and reduces damage to the ecological environment.

The lightweight isolation block is movably positioned between the main body of the mud tank and the independent mud mixing component to isolate and form a mud mixing zone; after the lightweight isolation block is removed, the new mud after mixing can be mixed with the old mud in the tank. The independent mud mixing assembly is located on one side of the mud tank body, and includes a motor, a protective cover, an upper mixing spiral blade and a lower mixing spiral blade, wherein the upper mixing spiral blade and the lower mixing spiral blade rotate in opposite directions.

[0012] Preferably, the motor is fixed on a motor mounting bracket, and the motor housing is made of aluminum alloy or heat-resistant carbon fiber material to facilitate rapid hoisting of the UAV. In use, the motor mounting bracket is fixed on the frame, a first gear is fixed on the output shaft of the motor, a second gear meshes on one side of the first gear, a third gear meshes on one side of the second gear, a fourth gear meshes on the outer side of the third gear, and a fifth gear meshes on one side of the fourth gear.

[0013] Preferably, the first gear, the third gear, and the fourth gear are all mounted inside the motor mounting bracket via a rotating shaft.

[0014] Preferably, the second gear is connected to the lower stirring blade shaft, the bottom of the fifth gear is connected to the upper stirring blade shaft, the lower stirring blade shaft is also connected to the fifth gear, and the lower stirring blade shaft is placed inside the upper stirring blade shaft.

[0015] Preferably, the second gear is connected to the lower stirring spiral blade via the lower stirring blade shaft, and the fifth gear is connected to the upper stirring rotating blade via the upper stirring blade shaft.

[0016] Preferably, the protective cover is located at the bottom of the motor mounting bracket, and the chamfering and grinding precision of the protective cover is ≥0.8μm to prevent the independent stirring component from scratching the waterproof cloth; the protective cover is made of all-aluminum alloy to reduce the weight of the independent stirring component and facilitate rapid hoisting and transportation by drones for exploration in plateau and mountainous areas.

Detailed Implementation

[0021] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Example 1 like Figure 1-2 As shown, the present invention provides a convenient drilling mud preparation and storage device suitable for complex terrain, including a mud tank body, a lightweight isolation block 3 and an independent mud mixing component; The main body of the mud tank consists of a frame 1 and a waterproof fabric 2. The frame 1 is a detachable stainless steel frame, and the frame 1 uses a quick-connect + wedge-shaped self-locking structure to detachably connect the components, ensuring the reliability of the connection between the frames 1 while allowing for quick disassembly and assembly. A drain outlet 6 is provided on the outside of the frame 1, through which the mud inside the mud tank can be discharged.

[0024] The size of skeleton 1 is adjustable according to the drilling depth; the size adjustment range of skeleton 1 includes small-sized specifications (volume 5-8m³) corresponding to shallow drilling (hole depth ≤ 50m). 3 Large-size specifications (volume 10-15m³) corresponding to medium-deep holes (hole depth 50-150m) 3 The dimensional parameters are determined by calculating the drilling depth and the amount of mud required per hole.

[0025] Waterproof fabric 2 is made of extra-thick 1000G waterproof fabric. The combined weight of waterproof fabric 2 and frame 1 is ≤200kg, which is convenient for unmanned hoisting and transportation, and meets the special requirements of plateau and high mountain environments.

[0026] The waterproof fabric 2 is detachably connected to the frame 1. Reinforcing buttonholes are sewn along the edges of the waterproof fabric 2, which is then secured to the frame 1 with clips. Furthermore, the waterproof fabric 2 can be disassembled and folded for transport (folded volume ≤ 0.2m³). 3 If a part is damaged, the damaged area can be cut and replaced instead of replacing the whole thing.

[0027] The lightweight isolation block 3 is movably placed between the main body of the mud tank and the independent mud mixing component to isolate and form the mud mixing zone.

[0028] When the mud properties need to be adjusted, a lightweight isolation block 3 can be placed to isolate a portion of the volume. After the mud is mixed, the lightweight isolation block 3 can be removed to mix the mixed mud with the old mud in the tank. This step can be repeated to adjust the mud properties.

[0029] The lightweight isolation block 3 is made of high-strength engineering plastic. The bottom of the lightweight isolation block 3 is equipped with a sealing strip that is compatible with the bottom of the mud tank body. This can prevent mud leakage during insertion and removal. The side of the lightweight isolation block 3 is equipped with a non-slip handle for easy manual operation.

[0030] The independent mud mixing unit is located on one side of the main body of the mud tank, and its weight is controlled within 200 kg, which facilitates transportation by unmanned hoisting. The independent mud mixing unit includes a motor 4, a protective cover 16, an upper mixing auger 12 and a lower mixing auger 13, with the upper mixing auger 12 and the lower mixing auger 13 rotating in opposite directions.

[0031] The motor 4 is fixed on the motor mounting bracket 5, which is fixed on the frame 1. A first gear 7 is fixed on the output shaft of the motor 4. A second gear 8 is meshed on one side of the first gear 7. A third gear 9 is meshed on one side of the second gear 8. A fourth gear 10 is meshed on the outside of the third gear 9. A fifth gear 11 is meshed on one side of the fourth gear 10.

[0032] The first gear 7, the third gear 9, and the fourth gear 10 are all mounted inside the motor mounting bracket 5 via rotating shafts, thereby limiting the motor and ensuring the normal operation of the gear set.

[0033] The second gear 8 is connected to the lower stirring blade shaft 15, and the bottom of the fifth gear 11 is connected to the upper stirring blade shaft 14. The lower stirring blade shaft 15 also passes through the fifth gear 11 and is placed inside the upper stirring blade shaft 14.

[0034] Meanwhile, the second gear 8 is connected to the lower stirring spiral blade 13 via the lower stirring blade shaft 15, and the fifth gear 11 is connected to the upper stirring spiral blade 12 via the upper stirring blade shaft 14.

[0035] In summary, the operation process of an independent mud mixing unit is as follows: The motor 4 drives the first gear 7 to rotate, which in turn drives the second gear 8 to rotate. The second gear 8 transmits power to the fifth gear 11 through the third gear 9 and the fourth gear 10, thus making the rotation directions of the second gear 8 and the fifth gear 11 opposite. This, in turn, drives the lower stirring blade 13 and the upper stirring blade 12 through the lower stirring blade shaft 15 and the upper stirring blade shaft 14, respectively. This makes the lower stirring blade 13 and the upper stirring blade 12 rotate in opposite directions, thereby reducing the torque generated during stirring and enhancing the stability of the stirring device.

[0036] The protective cover 16 is located at the bottom of the motor mounting bracket 5. The protective cover 16 is made of lightweight aluminum alloy to reduce weight. The chamfering and grinding precision of the protective cover 16 is ≥0.8μm; this prevents the waterproof cloth 2 from colliding with the protective cover 16 and scratching the waterproof cloth 2 during the stirring process.

[0037] Therefore, the present invention employs a convenient drilling mud preparation and storage device suitable for complex terrain, thereby realizing the recycling of resources, reducing energy consumption and costs, effectively reducing environmental pollutant emissions, and minimizing damage to the ecological environment.

[0038] It is worth noting that all the contents not described in detail in this invention are existing technologies and are well known to those skilled in the art.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
