Description

Technical Field

[0001] This utility model relates to the field of rock and soil monitoring technology, and in particular to a borehole suspension structure and a deep geological inclinometer device. Background Technology

[0002] In deep-hole inclinometer monitoring, sensors need to be lowered to different depths inside the inclinometer tube via cables to collect inclination data. Existing technologies have the following problems: Insufficient sensor extension: When the sensor string is lowered, it is easily affected by gravity or friction from the tube wall, which may cause some sensors to fold or tilt, resulting in data distortion. Unstable positioning: Traditional manual cable lifting makes it difficult to accurately control the position, and the sensor is prone to falling due to hand tremors or cable slippage; Low operating efficiency: The sensor string orientation needs to be adjusted repeatedly, which is time-consuming and labor-intensive, especially in deep holes (>50m).

[0003] Therefore, it is necessary to provide a new orifice suspension structure and a deep geological surveying device to solve the above-mentioned technical problems. Utility Model Content

[0004] The main purpose of this utility model is to provide a borehole suspension structure and a deep geological surveying device, which aims to solve the problems of unstable suspension effect and low operation efficiency of existing devices.

[0005] To achieve the above objectives, this utility model proposes an orifice suspension structure, which includes a suspension flange, a suspension cable, a suspension bracket, a suspension drive mechanism, and a positioning pin. The suspension flange is fixedly installed at the orifice opening of the channel. The suspension flange has a guide cable hole arranged horizontally and a limiting hole arranged vertically. The first end of the suspension cable is connected to the output shaft of the suspension drive mechanism, and the second end passes through the guide cable hole and is connected to the suspension bracket. The suspension bracket is used for the object to be suspended. The suspension drive mechanism can drive the suspension cable to lower or retract. The positioning pin can pass through the limiting hole and fix the suspension cable on the suspension flange.

[0006] Optionally, the suspension cable is provided with a plurality of spaced adjustment holes, and the positioning pin can pass through any of the adjustment holes to limit the suspension cable.

The annular side panel is disposed on the base plate. The guide cable hole is led out by the suspension drive mechanism, passes through the guide cable hole, and is connected to the suspension bracket. The connection between the annular side panel and the base plate forms a stepped surface, and the stepped surface supports the edge of the orifice.

[0010] Optionally, the base plate is further provided with a first locking hole; the positioning pin is provided with a second locking hole; the orifice suspension structure further includes a locking member, which passes through the second locking hole and the first locking hole in sequence to lock the positioning pin onto the first locking hole.

[0024] This utility model proposes a borehole suspension structure and a deep geological inclinometer device, aiming to solve the problems of unstable suspension effect and low operation efficiency of existing devices.

[0025] See Figures 1 to 3 This embodiment provides an orifice suspension structure for suspending a suspension bracket 3 within an orifice. The orifice suspension structure includes a suspension flange 1, a suspension drive mechanism, a suspension cable 2, and a positioning pin 4. The suspension flange 1 is fixedly installed at the orifice opening of the orifice. The suspension flange 1 has a guide cable hole 1.1.1 arranged in the horizontal direction and a limiting hole 1.1.2 arranged in the vertical direction. The first end of the suspension cable 2 is connected to the output shaft of the suspension drive mechanism, and the second end passes through the guide cable hole 1.1.1 and is connected to the suspension bracket 3. The suspension drive mechanism can drive the suspension cable 2 to be lowered or retracted. The positioning pin 4 can pass through the limiting hole 1.1.2 and fix the suspension cable 2 to the suspension flange 1. In actual operation, the suspension drive mechanism can drive the suspension cable 2 to lower or retract, thereby causing the suspension bracket 3 to descend or rise within the channel. By limiting the suspension cable 2 with the positioning pin 4, the suspension bracket 3 can be locked at different height positions, solving the problem of uneven force caused by traditional cable lifting. This is beneficial to improving the work efficiency and stability of the suspension process, ensuring work safety, and effectively preventing the suspension bracket 3 from falling.

[0026] In this embodiment, the positioning pin 4 is made of stainless steel and its diameter matches the 2.1 hole of the chain link (Ø6mm). After insertion, it forms a mechanical self-locking mechanism. Preferably, the positioning pin 4 is made of 420 martensitic steel with surface hardening treatment, which can perform mechanical locking and anti-slip. The suspension cable 2 is made of 304 stainless steel with a 2.1 hole diameter of Ø6mm and a breaking force of ≥5kN, which can realize overall suspension and force transmission.

[0027] The suspension cable 2 is provided with multiple spaced adjustment holes 2.1.1, and the positioning pin 4 can pass through any one of the adjustment holes 2.1.1 to limit the suspension cable 2. The positioning pin 4 passes through the limiting hole 1.1.2 on the suspension flange 1 and any one of the adjustment holes 2.1.1 on the suspension cable 2 to limit the suspension cable 2. The multiple spaced adjustment holes 2.1.1 can meet the suspension requirements at different heights.

[0028] Specifically, the suspension cable 2 includes multiple chain links 2.1 connected in series, and each chain link 2.1 has an adjustment hole 2.1.1. The structure of using chain links 2.1 connected in series can not only realize the positioning pin 4 to limit the suspension cable 2, but also has higher stability compared to cables, thereby improving the stability of the suspension process.

[0029] Furthermore, there are two suspension cables 2, which are symmetrically arranged on the suspension bracket 3, and each suspension cable 2 is equipped with a corresponding suspension drive mechanism. The symmetrical arrangement of the two suspension cables 2, and their cooperation in suspending the suspension bracket 3, further improves the stability of the suspension process and reduces friction between the suspension bracket 3 and the surrounding environment.

[0030] Furthermore, the suspension flange 1 includes a base plate 1.1 and an annular side plate 1.2. The base plate 1.1 has a guide cable hole 1.1.1 corresponding to the suspension cable 2. The annular side plate 1.2 is set on the base plate 1.1. The guide cable hole 1.1.1 is led out by the suspension drive mechanism, passes through the guide cable hole 1.1.1, and connects to the suspension bracket 3. The connection between the annular side plate 1.2 and the base plate 1.1 forms a stepped surface 1.3, which supports the edge of the orifice. The suspension flange 1 can be fixedly set at the edge of the orifice through the stepped surface 1.3. The suspension cable 2 passes through the guide cable hole 1.1.1 on the base plate 1.1 and connects to the suspension bracket 3, and is limited by the positioning pin 4, which not only ensures the installation strength of the suspension flange 1, but also realizes the locking of the suspension bracket 3 at different heights.

[0031] In this embodiment, the base plate 1.1 is also provided with a first locking hole 1.1.3; the positioning pin 4 is provided with a second locking hole 4.1; the orifice suspension structure also includes a locking member, which passes through the second locking hole 4.1 and the first locking hole 1.1.3 in sequence to lock the positioning pin 4 in the first locking hole 1.1.3. The positioning pin 4 is locked to the suspension flange 1 by the locking member, which further improves the limiting effect of the positioning pin 4 on the suspension cable 2, prevents displacement caused by vibration or accidental pulling, and avoids the positioning pin 4 from disengaging from the adjustment hole 2.1.1 on the suspension cable 2, which would cause the suspended object on the suspension bracket 3 to fall.

[0032] This embodiment also provides a deep geological inclinometer, including an inclinometer tube, a data acquisition module 5, a monitoring module, and the aforementioned borehole suspension structure. The inclinometer tube is disposed within the borehole and is fitted against the inner wall of the borehole. The first end of the data acquisition module 5 is connected to the suspension cable 2 via a suspension bracket 3, and the second end is connected to the monitoring module. The deep geological inclinometer also includes a universal joint 6, and the second end of the data acquisition module 5 is movably connected to the monitoring module via the universal joint 6. The monitoring module includes multiple sensors connected in series.

[0033] In this embodiment, the objects to be suspended are the acquisition module 5 and the monitoring module, and the end of the suspension cable 2 is locked to the acquisition module 5. In this embodiment, the monitoring module is suspended by the suspension cable 2 composed of chain links 2.1. After installation, the suspension cable 2 is lifted to fully extend each sensor of the monitoring module, avoiding measurement errors caused by folding and helping to maintain data monitoring accuracy. Then, the positioning pin 4 is inserted into the chain hole (i.e., the adjustment hole 2.1.1) to fix the position, completely avoiding the problem of uneven force caused by traditional cable lifting. Furthermore, the acquisition module 5 is rigidly connected to the sensor string through a universal joint, further ensuring uniform force.

[0034] This embodiment is applicable to various standard inclinometer tubes (Ø70–90mm) and is compatible with mainstream deep inclinometer sensors on the market.

[0035] In this embodiment, the specific steps for using a deep geological surveying device to perform surveying operations are as follows: Step 1: Install the suspension device, specifically: The suspension device is fixed to the inclinometer tube opening via a flange, ensuring that the entire assembly is aligned with the tube axis.

[0036] Step 2: Connect the sensor string, specifically: The bottom end of the chain (suspension cable 2) is connected to the top acquisition module 5 of the sensor string, and the whole chain is lowered to the target depth. At this time, the chain hangs down naturally.

[0037] Step 3: Enhance chain and positioning, specifically: Pull the top of the chain upwards to fully extend the sensor string; Select the corresponding link 2.1 hole, insert the positioning pin 4, and the chain position will be fixed.

[0038] Step 4: Data collection and maintenance, specifically: During sensor operation, positioning pin 4 bears the entire weight of the string and there is no risk of it falling. When the depth needs to be adjusted, pull out the positioning pin 4 and move the chain to the new chain link 2.1 hole to re-secure it.

[0039] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
