Description

Technical Field

[0001] This utility model relates to the field of deep well measurement equipment technology, and more specifically, to a locking device for the telescopic rod of a deep well measurement instrument to prevent deviation. Background Technology

[0002] Deep well measuring instruments are widely used in fields such as deep well exploration, geological monitoring, and downhole engineering inspection. The main unit of a deep well measuring instrument is usually connected to a detection probe via a transmission cable. In actual use, the transmission cable is usually unrolled and the detection probe is lowered into the deep well to perform measurement operations.

[0003] Because the measurement locations inside the deep well vary, the probe can be directly lowered to the edge of the well for testing. However, when measuring the center of the well, the transmission cable is too soft to be lowered to the exact center. In this case, a telescopic rod is needed for support. The telescopic rod is placed horizontally with its end extending directly above the center of the well. The cable is then guided by a guide mechanism on the telescopic rod, allowing the probe to be lowered to the top center of the well.

[0004] However, most deep well measuring instruments' telescopic rods are simply placed on a base on one side of the well without a corresponding fixing structure. This makes them susceptible to human interference or external wind interference, causing the rod's position to shift. Once the rod shifts, the supporting cables and detection probes will also shift, affecting the measurement results. Therefore, we propose a displacement-preventing locking device for the telescopic rod of a deep well measuring instrument. Utility Model Content

[0005] The purpose of this invention is to provide a locking device for the telescopic rod of a deep well measuring instrument to prevent deviation, thereby solving the defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A locking device for a telescopic rod of a deep well measuring instrument to prevent deviation includes a telescopic rod body. A locking assembly is provided at the end of the telescopic rod body. The locking assembly includes an L-shaped plate fixedly installed at the end of the telescopic rod body. The vertical section of the L-shaped plate abuts against the inner wall of the deep well. Two symmetrical anchor rods are inserted into the top plate of the L-shaped plate. The anchor rods are inserted into the soil around the deep well for fixation. A vertical plate is fixedly installed on the bottom surface of the end plate of the L-shaped plate. A screw is threaded onto the vertical plate. A clamping plate is fixedly installed at the inner end of the screw. The clamping plate presses against the outer surface of the deep well.

[0008] Preferably, the top plate of the L-shaped plate is provided with two symmetrical insertion holes on the left and right sides, and the anchor rod is inserted into the insertion holes.

[0009] Preferably, a limiting plate is fixedly installed at the top of the anchor rod, and the limiting plate abuts against the top surface of the top plate of the L-shaped plate.

[0010] Preferably, a handle is fixedly installed at the outer end of the screw, and anti-slip stripes are provided on the inner side of the clamping plate.

[0011] Preferably, the telescopic rod body includes a first connecting rod, a second connecting rod disposed within the first connecting rod and slidably connected to the first connecting rod, and a third connecting rod disposed within the second connecting rod and slidably connected to the second connecting rod.

[0012] Preferably, the top surfaces of the first connecting rod and the second connecting rod are provided with sliding holes arranged along the length direction, and the top surfaces of the rear ends of the second connecting rod and the third connecting rod are fixedly installed with studs, which pass through the corresponding sliding holes and are slidably connected to the sliding holes;

[0013] Preferably, a locking knob is threaded onto the stud, and the locking knob abuts against the top surface of the corresponding connecting rod;

[0014] The above two settings can limit and fix the second and third links to prevent loosening.

[0015] Preferably, the front ends of the first connecting rod, the second connecting rod, and the third connecting rod are all fixedly installed with U-shaped frames. The U-shaped frames on the first connecting rod and the second connecting rod are vertically arranged, while the U-shaped frame on the third connecting rod is horizontally arranged. The front and rear side plates of the U-shaped frame are rotatably connected by two mutually symmetrical fixed pulleys through a rotating shaft, and the transmission cable of the deep well measuring instrument passes through the fixed pulleys.

[0016] This feature allows the cable to be guided using a fixed pulley, making the cable more stable during the winding and unwinding process.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model, by setting a locking component, uses the vertical section of the L-shaped plate to abut against the inner wall of the deep well, the anchor rod is inserted into the soil for fixation, and the screw drives the clamping plate to press against the outer surface of the deep well, thereby achieving multi-angle stable fixation of the end of the telescopic rod body. This effectively prevents the telescopic rod from shifting due to human interference or wind force, ensures the accurate position of the measuring probe, and improves the measurement effect.

[0019] 2. This utility model designs the telescopic rod body as a multi-stage telescopic structure including a first link, a second link, and a third link, and sets sliding holes, studs, and locking knobs between the links. This enables flexible adjustment of the telescopic rod length according to measurement needs, and reliably limits and fixes the adjusted links to prevent the telescopic rod from loosening and ensures stable measurement operations.

[0020] 3. This utility model achieves guiding support for the transmission cable of the deep well measuring instrument by installing U-shaped frames and fixed pulleys at the front ends of each connecting rod of the telescopic rod body. This keeps the cable stable during the winding and unwinding process, reduces the impact of cable swaying and offset on the position of the measuring probe, and further improves the measurement accuracy and reliability.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-4This utility model provides a technical solution: a locking device for a telescopic rod of a deep well measuring instrument to prevent deviation, including a telescopic rod body 1, a locking component 2 at the end of the telescopic rod body 1, and an L-shaped plate 20 fixedly installed at the end of the telescopic rod body 1. The vertical section of the L-shaped plate 20 abuts against the inner wall of the deep well. Two symmetrical anchor rods 22 are inserted into the top plate of the L-shaped plate 20 and are inserted into the soil around the deep well for fixing. A vertical plate 24 is fixedly installed on the bottom surface of the end plate of the L-shaped plate 20. A screw 25 is threaded onto the vertical plate 24. A clamping plate 26 is fixedly installed at the inner end of the screw 25 and is pressed against the outer surface of the deep well, so that the end of the telescopic rod body 1 and the deep well form a stable connection in multiple directions, effectively preventing the telescopic rod body 1 from deviating due to human interference or external wind force, ensuring the accurate position of the measuring probe, and improving the measurement effect.

[0030] like Figure 3 As shown, the top plate of the L-shaped plate 20 is provided with two symmetrical insertion holes 21 on the left and right. The anchor rod 22 is inserted into the insertion hole 21, which facilitates the installation and disassembly of the anchor rod 22. This allows the locking assembly 2 to be quickly installed in different deep well measurement scenarios, improving the ease of use and applicability of the device.

[0031] like Figure 3 As shown, a limiting plate 23 is fixedly installed at the top of the anchor rod 22. The limiting plate 23 abuts against the top surface of the L-shaped plate 20 to prevent the anchor rod 22 from being inserted too deeply or coming out, thus ensuring the stable fixing effect of the anchor rod 22.

[0032] like Figure 3 As shown, a handle 27 is fixedly installed on the outer end of the screw 25, which makes it easy for the operator to apply force to rotate the screw 25 and adjust the tightness of the clamping plate 26 against the outer surface of the deep well. Anti-slip stripes are provided on the inner side of the clamping plate 26 to increase the friction with the outer surface of the deep well, so that the clamping plate 26 can more firmly clamp the deep well, enhance the fixing effect of the locking component 2, and further prevent the telescopic rod body 1 from shifting.

[0033] like Figures 2-4 As shown, the telescopic rod body 1 includes a first connecting rod 10, a second connecting rod 11 disposed within the first connecting rod 10 and slidably connected to the first connecting rod 10, and a third connecting rod 12 disposed within the second connecting rod 11 and slidably connected to the second connecting rod 11. The end of the first connecting rod 10 is fixedly installed on the side plate of the L-shaped plate 20, so that the telescopic rod body 1 can flexibly adjust its length according to different needs of deep well measurement and meet diverse measurement scenarios.

[0034] like Figure 4As shown, the top surfaces of the first connecting rod 10 and the second connecting rod 11 are provided with sliding holes 13 arranged along the length direction. The top surfaces of the rear ends of the second connecting rod 11 and the third connecting rod 12 are fixedly installed with studs 14. The studs 14 pass through the corresponding sliding holes 13 and are slidably connected to the sliding holes 13. A locking knob 15 is threaded onto the studs 14. The locking knob 15 abuts against the top surface of the corresponding connecting rod to limit and fix the second connecting rod 11 and the third connecting rod 12, prevent the telescopic rod from loosening during use, and ensure stable measurement operation.

[0035] like Figure 4 As shown, U-shaped frames 16 are fixedly installed at the front ends of the first link 10, the second link 11, and the third link 12. The U-shaped frames 16 on the first link 10 and the second link 11 are vertically arranged, while the U-shaped frame 16 on the third link 12 is horizontally arranged. Two mutually symmetrical fixed pulleys 161 are rotatably connected between the front and rear plates of the U-shaped frame 16 via a rotating shaft. The transmission cable of the deep well measuring instrument passes through the fixed pulleys 161, which guide the cable and reduce the shaking and friction during the cable winding and unwinding process. This makes the cable winding and unwinding more stable and avoids the position of the measuring probe being affected by changes in the cable position, thereby further improving the measurement accuracy.

[0036] When using the anti-deviation deep well measuring instrument telescopic rod locking device of this utility model, first pass the transmission cable of the deep well measuring instrument through the fixed pulley 161 on the U-shaped frame 16 at the front end of the first connecting rod 10, the second connecting rod 11 and the third connecting rod 12. Guided by the fixed pulley 161, and then according to the measurement requirements, adjust the telescopic rod body 1 to a suitable length by adjusting the telescopic length of the first connecting rod 10, the second connecting rod 11 and the third connecting rod 12. Use the stud 14 to slide in the sliding hole 13, and then tighten the locking knob 15 to limit and fix the second connecting rod 11 and the third connecting rod 12.

[0037] Move the L-shaped plate 20 at the end of the telescopic rod body 1 to the deep well, so that the vertical section of the L-shaped plate 20 fits against the inner wall of the deep well. Insert the anchor rod 22 into the insertion hole 21 of the top plate of the L-shaped plate 20, and drive the anchor rod 22 into the soil around the deep well for fixation. The limiting plate 23 at the top of the anchor rod 22 abuts against the top surface of the L-shaped plate 20 to prevent the anchor rod from being over-inserted or detached.

[0038] Rotate the handle 27 at the end of the screw 25 to push the clamping plate 26 to press against the outer surface of the deep well. Its anti-slip stripes increase friction and further stabilize the locking component 2. Finally, lower the detection probe for stable measurement. After the measurement is completed, reverse the operation to complete the disassembly.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
