Description

Technical Field

[0001] This utility model belongs to the field of geotechnical engineering monitoring equipment, and in particular relates to a portable inclinometer. Background Technology

[0002] In geotechnical engineering fields such as water conservancy and hydropower, mining and metallurgy, transportation, and urban construction, inclinometers are widely used, primarily for measuring the dip and azimuth angles of boreholes. In existing inclinometer techniques, there is a certain proportional relationship between the borehole diameter, drill rod diameter, and inclinometer rod diameter; that is, the borehole diameter is larger than the drill rod diameter, and the drill rod diameter is larger than the inclinometer rod diameter. To avoid magnetic interference from the drill rod, the inclinometer needs to extend a considerable distance from the drill rod. However, this design results in inconsistent diameters of the front and rear supports during insertion, making it impossible to ensure parallelism with the borehole wall at the measurement point, thus affecting the accuracy of the inclinometer data. This error problem is particularly pronounced in deep-hole exploration, special-purpose boreholes (such as filling holes), and large-diameter boreholes (such as hydrological holes and engineering exploration holes), and existing technologies struggle to meet the demands of high-precision inclinometer measurements. Furthermore, while directional drilling rigs can solve the problem of construction deviation, their high cost makes widespread adoption difficult. When using ordinary inclinometers, poor management often leads to disorganized storage and inability to assemble them promptly when needed, which reduces work efficiency. Utility Model Content

[0004] To achieve the purpose of this utility model, the following technical solution is adopted: a portable inclinometer, comprising an inclinometer structure and a storage structure. The inclinometer structure includes connecting rod A, connecting rod B, and connecting rod C; connecting rod A, connecting rod B, and connecting rod C are hollow and open; connecting rod A, connecting rod B, and connecting rod C are connected by threads; one end of connecting rod B is provided with a shock absorber a; one end of connecting rod C is provided with a shock absorber b; one end of connecting rod A is fitted with a stabilizing block one; the other end of connecting rod B is fitted with a stabilizing block two; a hollow limiting block is provided inside one end of connecting rod B near the opening; a counterweight is placed inside one end of connecting rod B to cooperate with the limiting block; the inclinometer structure, stabilizing block one, stabilizing block two, and counterweight are all placed inside the storage structure.

[0005] Furthermore, the storage structure includes a lid and a body; the lid is movably connected to one side of the body via a hinge; a safety buckle is provided on the other side of the lid; a lock hole is provided on the same side of the body as the lid to cooperate with the safety buckle; a handle is provided in the middle of one side of the body; a storage block is placed inside the body against the box wall; the upper surface of the storage block has four grooves a and two grooves b.

[0010] Compared with the prior art, this utility model has the following advantages:

[0011] This inclinometer device, with its threaded connecting rods A, B, and C, facilitates assembly by construction personnel.

Detailed Implementation

[0019] The technical solutions of the present utility model will now be clearly and completely described with reference to the accompanying drawings of the embodiments thereof:

[0020] like Figure 1-6As shown, a portable inclinometer includes an inclinometer structure and a storage structure 1, with connecting rods A2, B3, and C4. Connecting rods A2, B3, and C4 are hollow and open, facilitating the connection of steel cables through the entire inclinometer structure. A secure anchor head is connected to the lower end of the inclinometer structure. Connecting rods A2, B3, and C4 are connected by threads, allowing for quick assembly and disassembly of the entire device while maintaining structural strength and stability. A shock absorber a8 is provided at one end of connecting rod B3. One end of connecting rod C4 is equipped with a shock absorber b9. These two shock absorbers can effectively absorb vibrations that may occur during the measurement process, ensuring the accuracy of the measurement results. One end of connecting rod A2 is fitted with a stabilizing block 6, which is secured to the upper part of shock absorber a8. The other end of connecting rod B3 is fitted with a stabilizing block 7, which is secured to the upper part of shock absorber b9. Because the inner and outer diameters of the original anchor head could not match the inner diameter of the existing drill rod, the inclinometer failed to measure the inclination normally. The newly added stabilizing blocks 6 and 7 prevent this from happening during inclinometer measurement. To address the issues of instrument damage and inclinometer detachment, stabilizing blocks 6 and 7 are designed to fit snugly against the drill rod's inner diameter, ensuring the inclinometer structure is parallel to the borehole wall at the measuring point. This results in uniform and symmetrical forces acting on the inclinometer device, preventing damage to the contact surfaces and enabling accurate inclinometer data measurement within the borehole. The stabilizing blocks 6 and 7 are made of thermoplastic resin, providing sufficient weight for stability while also offering some elasticity to adapt to different measuring surfaces. Furthermore, they do not generate magnetic fields during use. To prevent the inclinometer from getting stuck during operation, stabilizing blocks 6 and 7 are designed as sieve-shaped large-aperture discs, allowing debris to be discharged through the pores. This prevents debris from getting stuck on the borehole wall during the inclinometer's movement into the measured position. A hollow limiting block 12 is located near the opening at one end of the connecting rod B3. A counterweight 5 is placed inside the connecting rod B3 to work in conjunction with the limiting block 12. The inclinometer structure, stabilizing blocks 6, 7, and counterweight 5 are all housed inside the storage structure 1 to ensure the balance and stability of the device during use.

[0021] Specifically, the storage structure 1 includes a lid 101 and a body 102; the lid 101 is movably connected to one side of the body 102 via a hinge, facilitating opening and closing by the user; a safety buckle 13 is provided on the other side of the lid 101; a lock hole 15 is provided on the same side of the body 102 as the lid 101, which works in conjunction with the safety buckle 13 to ensure that the device will not be accidentally opened during carrying; a handle 14 is provided in the middle of one side of the body 102 for easy carrying; a storage block 103 is placed inside the body 102 against the body wall. The upper surface of the storage block 103 is provided with four grooves a104 and two grooves b105. The four grooves a104 are of different lengths and are adapted to the dimensions of connecting rod A2, connecting rod B3, connecting rod C4 and counterweight 5. In order to better fit the inner wall of the groove and prevent it from falling off the storage block 103 due to shaking during movement, the two grooves b105 are both circular and adapted to the dimensions of stabilizing block 6 and stabilizing block 7. The storage block 103 is made of plastic bubble wrap to ensure that these components will not move or be damaged during transportation and storage.

[0022] Specifically, one end of the connecting rod A2 is provided with a protruding second bolt head 11; the other end of the connecting rod B3 is provided with a protruding first bolt head 10; the inner side of the other end of the connecting rod B3 and one end of the connecting rod C4 are both provided with internal threads; the second bolt head 11 is inserted into the inner side of the other end of the connecting rod B3 and fixed by internal thread; the first bolt head 10 is inserted into one end of the connecting rod C4 and fixed by internal thread, making the connection between the connecting rods more firm and reliable.

[0023] Specifically, the diameter of the first stabilizing block 6 and the second stabilizing block 7 is 298mm; both the first stabilizing block 6 and the second stabilizing block 7 have through holes in the middle.

[0024] Specifically, the total length of connecting rods A2, B3, and C4 is 287cm. The original length of the inclinometer rod, which was 350cm, is shortened to 287cm. This shortens the swing arm length of the inclinometer rod under the drill bit, thereby reducing the swing amplitude of the inclinometer rod under the drill bit and reducing the actual time required for stabilization, thus stabilizing the inclinometer rod.

[0025] During use, firstly, the connecting rods A2, B3, and C4 are connected in sequence via threaded connections. One end of connecting rod A2 has a protruding second bolt head 11, which is inserted into the internal thread of connecting rod B3 and tightened. Similarly, the other end of connecting rod B3 has a protruding first bolt head 10, which is inserted into the internal thread of connecting rod C4 and tightened. Stabilizing block 6 is fitted onto one end of connecting rod A2, ensuring it is secured to the upper part of shock absorber a8. Stabilizing block 7 is fitted onto the other end of connecting rod B3, securing it to the upper part of shock absorber b9. A counterweight 5 is placed above the limiting block 12 inside one end of connecting rod B3. Next, the assembled inclinometer device is threaded through the inclinometer structure with a steel cable, and a secure anchor head is connected to the lower end of the inclinometer structure. The inclinometer structure is then placed into the predetermined measuring hole, ensuring that stabilizing blocks 6 and 7 align with the inner diameter of the drill rod during placement, making the inclinometer structure parallel to the hole wall at the measuring point. The inclinometer is then started for measurement. Shock absorbers a8 and b9 effectively absorb any vibrations that may occur during the measurement process. Finally, after the measurement is completed, the inclinometer structure, stabilizing blocks 6, stabilizing blocks 7, and counterweight 5 are disassembled. The case cover 101 of the storage structure 1 is opened, and the components are placed into the corresponding grooves a104 and b105 on the storage block 103. The case cover 101 is closed, and the case 102 is locked using the safety buckle 13 and the locking hole 15 to ensure that the device will not be accidentally opened during transport. The storage structure 1 is then carried using the handle 14 on one side of the case 102.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
