TECHNICAL FIELD

[0001] The present application relates to the technical field of depth measurement, in particular to a rock and soil geological exploration depth measurement device. BACKGROUND

[0002] The purpose of geotechnical engineering investigation is to investigate and analyze the construction site by using testing means and methods, and in the field of rock and soil geological exploration, depth measurement is a crucial link, which is not only related to the accurate evaluation of geological structure, but also directly affects the safety and economy of subsequent engineering design and construction. Common depth measurement devices mainly include well depth rulers, etc. The well depth ruler generally includes a measuring head, a steel cable, a winding reel, a receiving system, etc. The steel cable is a flexible metal band with scale marks. During measurement, the steel cable is wound outside the winding reel, and then the measuring head is lowered into the well using the steel cable. The sensor on the measuring head sends information to the receiving system to help the staff determine whether the measuring head reaches the water surface and the well bottom. Then the length of the steel cable is lowered to measure the well depth.

[0003] However, the common depth measurement devices all use manual winding of the winding reel for measurement, which not only depends on the stability of manual winding, but also is prone to jamming and winding in complex geological environments due to the single wheel set transmission design. Especially in mountainous or soft soil exploration, the offset or jamming of the steel cable will directly lead to distortion of the depth data. In addition, when the ground vibrates or the device is not stable during field exploration, the measuring components will also resonate. The traditional rigid connection structure cannot buffer the instantaneous impact force, resulting in shaking of the steel cable and swinging of the counterweight, which affects the stability of depth measurement.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0037] Embodiment one, please refer to Figures 1 to 6 ​The rock geology exploration depth measuring device provided by the application has the advantages that the device is simple in structure, convenient to use, and capable of measuring the depth of rock geology exploration in a linear and stable manner.

[0038] The steel ruler cable 12 is driven between the rotating sleeve wheel 8, the extrusion mechanism, the transmission double wheel set 26 and the pay-off wheel 27, and a depth measurement transmission path is formed.

[0039] The frame structure is rigidly fixed with the fixed base plate 1, and the rotating sleeve wheel 8, the forward and reverse linkage mechanism, the extrusion mechanism, the transmission double wheel set 26 and the pay-off wheel 27 form a stable mechanical arrangement.

[0040] The forward and reverse linkage mechanism is fixedly connected with the sponge cleaning block 17 at one end, so that the steel ruler cable 12 rotates in the forward and reverse directions, and the sponge cleaning block 17 is in self-adaptive contact with the scale surface of the steel ruler cable 12 when the steel ruler cable 12 is wound in the forward and reverse directions.

[0041] The extrusion mechanism is located below the sponge cleaning block 17, and when the forward and reverse linkage mechanism drives the steel ruler cable 12 to be wound in the forward and reverse directions, a constant pre-tightening force is applied to the non-scale surface of the steel ruler cable 12, and then the sponge cleaning block 17 is in contact with the scale surface.

[0042] More specifically, in the embodiment, the overall device operation process is as follows:

[0043] Device erection and fixation: the fixed base plate 1 is placed horizontally on the ground of the monitoring point of rock geology exploration, and is fixed by expansion bolts or other counterweights to ensure that the frame structure is rigidly connected with the fixed base plate 1, forming a stable mechanical arrangement, and avoiding displacement of the device caused by vibration of the rock geology construction site.

[0044] Steel ruler cable deployment: the forward and reverse linkage mechanism drives the rotating sleeve wheel 8 to release the steel ruler cable 12, and the counterweight 13 drives the steel ruler cable 12 to pass through the extrusion mechanism, the transmission double wheel set 26 and the pay-off wheel 27 in sequence under the action of gravity, forming a depth measurement transmission path for rock geology exploration, and the counterweight 13 and the steel ruler cable 12 enter the drill hole of the rock geology to measure the depth, and during the measurement process, the counterweight 13 quickly sinks to the target position of the rock geology exploration, and the transmission double wheel set 26 and the pay-off wheel 27 cooperatively limit the deviation of the steel ruler cable 12 to ensure linear transmission of the depth data.

[0045] Rolling cleaning linkage: after the depth measurement is completed, the forward and reverse linkage mechanism is started again to drive the steel ruler cable 12 to roll, the sponge cleaning block 17 is in self-adaptive contact with the scale surface, and synchronous cleaning of environmental pollutants such as silt and algae attached to the scale surface is performed, the constant pre-tightening force of the extrusion mechanism is applied to the non-scale surface, so that the cleaning block is tightly attached, and the instantaneous force generated by water flow impact or equipment vibration is absorbed through elastic deformation, so as to avoid scale wear;

[0046] In addition, it is also worth mentioning that when the forward and reverse linkage mechanism drives the rotating sleeve wheel 8 to release the steel ruler cable 12 for depth measurement, the sponge cleaning block 17 is still in self-adaptive contact with the scale surface and pre-cleans the scale surface of the steel ruler cable 12, and the extrusion mechanism also applies a constant pre-tightening force to the non-scale surface to provide auxiliary power for the release transmission of the steel ruler cable 12.

[0047] At this point, the rigidity of the frame structure and the coaxial arrangement provide a stable mechanical support system for the rotating sleeve wheel 8, the transmission double wheel set 26, and the pay-off wheel 27, providing a constant reference for depth measurement. The angle optimization of the rotating sleeve wheel 8, the extrusion mechanism, the transmission double wheel set 26, and the pay-off wheel 27 in cooperation with the inclined support ensures that the steel ruler cable maintains a linear trajectory during the winding and unwinding process. The forward and reverse linkage mechanism drives the sponge cleaning block 17 to form a "multi-frequency light pressure" cleaning trajectory, synchronously realizing the winding of the steel ruler cable 12 and the removal of dirt from the scale surface, eliminating the need for manual cleaning. The constant pre-tightening force of the extrusion mechanism ensures that the sponge cleaning block 17 is self-adaptively attached to the scale surface while buffering the contact pressure through elastic deformation to prevent scale wear. In addition, the double elastic buffer system solves the measurement distortion problem caused by resonance in traditional rigid structures. The mechanical linkage design driven by the forward and reverse motors simultaneously realizes the winding, cleaning, and guiding actions of the steel ruler cable 12 without the need for additional power sources or manual intervention.

[0048] In addition, the frame structure includes:

[0049] The fixed support 2 is connected to the inclined support 3 on one side, the motor bracket 4 is fixedly installed on the upper surface of the fixed base plate 1 away from the fixed support 2, and the fixed support 2 and the motor bracket 4 are horizontally coaxially arranged;

[0050] The first support 5 and the second support 6 are fixedly installed on the other side surface of the fixed base plate 1 away from the motor bracket 4, and the third support 7 is fixedly installed on the upper surface of the fixed base plate 1 near the pay-off wheel 27.

[0051] For the frame structure, the fixed support 2 and the motor frame 4 are fixed transversely and coaxially on the fixed base plate 1, which ensures that the transmission roller 11 of the forward and reverse linkage mechanism is coaxial with the rotating sleeve wheel 8, reduces the transmission eccentric error, and ensures that the coaxial error of the transmission roller 11 and the output shaft of the forward and reverse motor 9 is reduced through the positioning of the reference hole during processing, thereby avoiding the fluctuation of the steel ruler cable 12 winding tension caused by eccentric rotation.

[0052] The first support 5 and the second support 6 are installed on the other side of the fixed base plate 1, which are distributed transversely and coaxially, and provide rigid support for the forward and reverse linkage mechanism and the extrusion mechanism.

[0053] The third support 7 is longitudinally and coaxially arranged with the second support 6, which ensures that the transmission double wheel set 26 and the extrusion mechanism are height-matched, so that the steel ruler cable 12 can be kept vertical transmission under complex terrain.

[0054] The forward and reverse linkage mechanism comprises:

[0055] The forward and reverse motor 9 is fixedly connected with the driving gear 10 at the output end, and the driving gear 10 is meshingly connected with the driven gear 14 on one side, the driven gear 14 is fixedly connected with the driven roller 15 on one side of the shaft surface, and the driven roller 15 is fixedly connected with the winding roller 16 at one end.

[0056] The forward and reverse motor 9 is fixedly installed in the interior of the motor frame 4, the rotating sleeve wheel 8 is installed on the fixed support 2, the driving gear 10 is fixedly connected with the transmission roller 11 on the surface away from the forward and reverse motor 9, the rotating sleeve wheel 8 is fixedly sleeved on the outer surface of the transmission roller 11, and the other end of the transmission roller 11 is rotationally limited in the interior of the fixed support 2.

[0057] The driven gear 14 is rotationally installed on the first support 5 through the limiting sleeve set.

[0058] The sponge cleaning block 17 is fixedly connected to the arc surface at one end of the winding roller 16.

[0059] For the forward and reverse linkage mechanism, the forward and reverse motor 9 is fixed in the motor frame 4, the output end drives the driving gear 10 to rotate, drives the driven gear 14 to rotate through the meshing of the teeth, drives the winding roller 16 to rotate through the driven roller 15, and realizes the mechanical transmission of power from the motor to the cleaning assembly, without the need for an additional driving source.

[0060] Synchronization of winding and cleaning: the driving gear 10 drives the transmission roller 11 to rotate, so that the rotating sleeve 8 winds the steel cable 12, the synchronous rotating of the driven roller 16, and the arc-shaped surface of the sponge cleaning block 17 adheres to the steel cable 12 scale surface along the rotating track, and after the measurement of the geological environment, the surface water stains and sludge are quickly removed to ensure clear reading. The driven gear 14 is stably rotated on the first support 5 through the limiting sleeve set to avoid transmission lag caused by gear meshing gap, and improve the winding accuracy. In addition, when the positive and negative motor 9 drives the driving gear 10 to rotate one circle, the driven gear 14 drives the driven roller 16 to rotate two circles, so that the sponge cleaning block 17 forms a "multi-frequency light pressure" cleaning mode on the steel cable 12. Compared with the constant speed transmission, the cleaning efficiency is greatly improved, and the scale wear caused by single pressure is avoided.

[0061] The extrusion mechanism comprises:

[0062] The two side surfaces of the arc pressing plate 18 are integrally connected with the extension plates 19, the upper surfaces of the extension plates 19 are fixedly connected with the conveying dynamic roller groups 20, and the other two side surfaces of the arc pressing plate 18 away from the extension plates 19 are fixedly connected with the baffles 22.

[0063] The lower surface of the arc pressing plate 18 and the upper surface of the second support 6 are fixedly connected with the spring groups 21, the two side surfaces of the second support 6 are fixedly connected with the side sliding plates 24, the center lower surface of the baffle 22 is provided with the groove 23, the upper surface of the side sliding plate 24 and the top wall of the groove 23 are welded with the springs 25, and the side sliding plate 24 is limitedly slid in the groove 23.

[0064] For the extrusion mechanism, the arc pressing plate 18 is elastically connected with the second support 6 through the spring groups 21, and in the natural state, the spring groups 21 are stretched, so that the conveying dynamic roller groups 20 on the arc pressing plate 18 are in contact with the non-scale surface of the steel cable 12, a constant pre-tightening force is applied, and the sponge cleaning block 17 is effectively adhered to the scale surface.

[0065] Vibration buffering and absorption: when the measurement site of the geological exploration produces vibration, the steel cable 12 drives the arc pressing plate 18 to displace up and down, the side sliding plate 24 slides in the groove 23, and the spring 25 is compressed or stretched to absorb the instantaneous impact force.

[0066] The baffle 22 limits the lateral swing of the arc pressing plate 18, and cooperates with the spring groups 21 to form double buffering, reduces the shaking amplitude of the steel cable 12, and improves the stability of the depth measurement.

[0067] In the above embodiment, on the basis of the above embodiment:

[0068] Further, the side upper surface of the fixed bottom plate 1 is provided with a rotating limiting groove 28 for the rotation of the driven gear 14.

[0069] More specifically, in the embodiment, the driven gear 14 is embedded into the rotation limiting groove 28 of the fixed bottom plate 1, and during the forward and reverse rotation, the rotation limiting groove 28 limits the radial jumping of the driven gear 14 through the side wall, ensures the stable gear meshing gap between the driving gear 10 and the driven gear 14, and avoids the mud and stones from entering the gear meshing surface to cause the jamming in the measurement environment of the geological exploration.

[0070] In addition, since the second support 6 and the arc pressing plate 18 are both arranged in the same direction and are adapted to the rotation angle of the sponge cleaning block 17.

[0071] Therefore, the second support 6 and the arc pressing plate 18 are both arranged in the same direction and are tangent to the arc-shaped rotation track formed by the driving roller 16 and the sponge cleaning block 17, which ensures the linear contact between the cleaning block and the scale surface of the steel cable 12 during the whole winding process and improves the dirt removal efficiency in the water environment.

[0072] Meanwhile, the inclined design makes the pre-tightening force of the extrusion mechanism uniformly distributed along the axial direction of the steel cable 12, which avoids the local pressure from being too large to cause the scale deformation.

[0073] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
