Description

Technical Field

[0001] This invention relates to the field of geological disaster monitoring technology, and in particular to a settling detection device for spoil heaps. Background Technology

[0002] Waste disposal sites are concentrated areas for the dumping of solid waste such as earthwork and construction debris generated during engineering construction. Their loose structure and poor stability make them highly susceptible to settlement and deformation under the influence of external factors such as rainfall, earthquakes, and changes in load, which can lead to geological disasters such as landslides and mudslides. Statistics show that the direct economic losses caused by waste disposal site instability in my country exceed 10 billion yuan annually, with indirect impacts being even more severe. Therefore, scientific and effective settlement monitoring of waste disposal sites is a crucial aspect of engineering construction and operation management.

[0003] In the stratified settling monitoring of waste disposal sites, the structure of the settling magnetic ring in the existing settling detection device is not compatible with the characteristics of the pore wall of the loose and porous waste material, making it impossible to achieve a tight fit and fixation. Most of the existing settling magnetic rings are rigid ring structures, and their fixing method mainly relies on the fit and compression between their own shape and the borehole wall, or with the assistance of simple elastic pads. However, their adaptability is poor when in use, which leads to the magnetic ring being unable to stably support the borehole wall, and it is very easy for it to loosen, slip or shift, thus losing the accurate monitoring function of the settling of the waste material at the corresponding depth. Summary of the Invention

The orifice wall positioning assembly includes a cavity formed inside a sliding ring. The side surface of the sliding ring has an arc-shaped groove arranged in a ring array. An arc-shaped positioning plate is rotatably connected inside the arc-shaped groove. A rotating shaft is fixedly installed inside the arc-shaped positioning plate. A first transmission gear is provided on the outer surface of the rotating shaft. A transmission gear ring is meshed with one side of several of the first transmission gears. The inner and outer sides of the transmission gear ring are provided with tooth grooves. A second transmission gear is meshed with the inner side wall of the transmission gear ring.

A second connecting rod is rotatably installed at one end of the first connecting rod. A slider is rotatably connected to one end of the second connecting rod. The slider slides through and is connected to the side surface of the sliding ring. In the initial state, the slider is in close contact with the outer surface of the settling guide tube.

[0005] Preferably, the outer surface of the settling conduit is provided with a guide groove, and the slider is slidably connected to the inside of the guide groove.

[0006] Preferably, a drive motor is mounted on the upper surface of the sliding ring through a protective shell, and the output end of the drive motor is fixedly mounted on the top of one of the rotating shafts through a retaining pin.

[0007] Preferably, the inner wall of the sliding ring is provided with an annular groove, an oil storage frame is fixedly installed inside the annular groove, a plurality of oil drain holes are provided in an annular array on the side surface of the oil storage frame, and an oil injection pipe is provided on the upper surface of the oil storage frame.

[0008] Preferably, the side surface of the oil storage frame is provided with a through hole, and an oil squeezing cylinder is fixedly installed on the side surface of the through hole. A piston plate is slidably connected inside the oil squeezing cylinder, and a sliding rod is fixedly installed on the side surface of the piston plate. One end of the sliding rod is rotatably connected to a third connecting rod, and the other end of the third connecting rod is rotatably connected to a driven rod. The driven rod is fixedly installed on the lower surface of the transmission gear ring.

[0009] Preferably, several of the settling conduits are spliced ​​together and installed, with a threaded cylinder fixedly installed on the inner side wall of the top of the settling conduit, and a connecting cylinder threadedly connected to the outer surface of the threaded cylinder, the connecting cylinder being fixedly installed on the lower surface of the upper settling conduit.

[0010] Preferably, the outer surface of the docking cylinder is provided with an annular groove, and a retaining ring is slidably connected to the surface of the annular groove. A retaining post is fixedly installed in an annular array on the lower surface of the retaining ring. The retaining post is slidably installed through the surface of the docking cylinder, and the lower surface of the settling guide tube below is provided with a retaining hole adapted to the retaining post.

[0011] Preferably, a first magnetic block is embedded on the lower surface of the retaining ring, and a second magnetic block that is magnetically connected to the first magnetic block is embedded in the inner bottom wall of the annular groove.

[0012] Preferably, a frame is provided on one side of the bottom cover of the pipe, and a battery and a controller are placed inside the frame. A solar panel electrically connected to the battery is installed on the top of the frame, and the controller is electrically connected to a drive motor and a settling magnetic ring.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting up a hole wall positioning component, the arc-shaped positioning plate can be driven to rotate outward and insert into the hole wall of the loose, porous waste slag body during use. At the same time, the slider slides outward to the periphery to disengage from the inside of the guide groove, releases the fixing on the surface of the settling guide tube and fixes it to the hole wall of the waste slag site. This replaces the problem of unstable fixing caused by the traditional rigid ring structure relying only on the fit and compression or simple elastic gasket. It enables the settling magnetic ring to form a mechanical anchoring tight fit with the porous and easily deformable waste slag body hole wall, improves the stability of the settling magnetic ring in the hole, effectively prevents loosening, slippage or displacement, and thus ensures accurate monitoring of the settling of waste slag body at the corresponding depth. 2. Through the setting of structures such as oil storage frame, oil drain hole, oil squeezing cylinder, piston plate and third connecting rod, when the transmission gear ring rotates and drives the arc-shaped positioning plate to unfold, it simultaneously drives the piston plate to squeeze the lubricating oil in the oil storage frame and discharge it from the oil drain hole. This can automatically or periodically replenish the lubricating medium to the contact surface between the settling guide 2 and the sliding ring 3, reduce the frictional resistance of the sliding ring when it moves on the settling guide, avoid the sliding jamming caused by the intrusion of mud and sand during long-term monitoring, ensure that the settling magnetic ring can slide freely when it settles with the waste slag, and ensure the authenticity of the monitoring data. 3. By using structures such as threaded cylinders, connecting cylinders, and retaining rings, several settling guide pipes are spliced ​​together and connected by threaded cylinders and connecting cylinders. This allows the settling guide pipes to be flexibly extended or shortened according to the detection depth, enhancing the adaptability of the device to monitoring conditions of waste disposal sites at different depths. At the same time, it effectively prevents the settling guide pipes from loosening due to vibration or external forces during use, improving the reliability and safety of the guide pipe connection during long-term monitoring.

[0014] In summary, this invention overcomes the shortcomings of the prior art and replaces the problem of unstable fixation caused by the traditional rigid ring structure relying solely on bonding and compression or simple elastic gaskets. It enables the settling magnetic ring to form a mechanically anchored and tightly bonded fit with the porous and easily deformable waste slag hole wall, improving the stability of the settling magnetic ring in the hole and effectively preventing loosening, slippage or displacement, thereby ensuring accurate monitoring of the settling of waste slag at the corresponding depth.

The orifice wall positioning assembly 6 includes a cavity formed inside the sliding ring 3. The side surface of the sliding ring 3 has an arc-shaped groove in a ring array. An arc-shaped positioning plate 601 is rotatably connected inside the arc-shaped groove. A rotating shaft is fixedly installed inside the arc-shaped positioning plate 601. A first transmission gear 602 is provided on the outer surface of the rotating shaft. A transmission gear ring 603 is meshed with one side of several first transmission gears 602. The inner and outer sides of the transmission gear ring 603 are provided with tooth grooves. A second transmission gear 604 is meshed with the inner side wall of the transmission gear ring 603. A rotating rod 605 is fixedly installed on the lower surface of the second transmission gear 604. A first connecting rod 606 is provided on the outer surface of the rotating rod 605. A second connecting rod 607 is rotatably installed at one end of the first connecting rod 606. A slider 608 is rotatably connected to one end of the second connecting rod 607. The slider 608 slides through and is connected to the side surface of the sliding ring 3. In the initial state, the slider 608 is in close contact with the outer surface of the settling guide 2.

[0020] Specifically, refer to Figures 1 to 6 As shown, a guide groove 7 is provided on the outer surface of the settling guide 2. The slider 608 is slidably connected to the inside of the guide groove 7, which can provide guidance for the sliding of the slider 608, prevent the slider 608 from deflecting during the movement, ensure the smoothness and reliability of the hole wall positioning component 6, and thus enhance the stability of the overall positioning mechanism.

[0021] Specifically, refer to Figures 1 to 6 As shown, a drive motor is mounted on the upper surface of the sliding ring 3 through a protective shell. The output end of the drive motor is fixedly mounted on the top of one of the rotating shafts through a clamping shaft. This facilitates the quick fixation and release of the settling magnetic ring 5 in deep holes or complex working conditions, thereby improving detection efficiency and the degree of automation of operation.

[0022] Example 2: Refer to Figure 4 and Figure 7 As shown, the difference between this embodiment and embodiment 1 is that the inner wall of the sliding ring 3 is provided with an annular groove, and an oil storage frame 8 is fixedly installed inside the annular groove. The side surface of the oil storage frame 8 is provided with a number of oil drain holes 9 in an annular array. An oil injection pipe is provided on the upper surface of the oil storage frame 8, which can automatically replenish the lubricating medium to the contact surface between the settling guide 2 and the sliding ring 3, reduce the frictional resistance of the sliding ring 3 when it moves on the settling guide 2, ensure that the settling magnetic ring 5 can slide freely when it settles with the waste slag, and ensure the authenticity of the monitoring data.

[0023] Specifically, refer to Figure 7As shown, a through hole is provided on the side surface of the oil storage frame 8. An oil squeezing cylinder 10 is fixedly installed on the side surface of the through hole. A piston plate 11 is slidably connected inside the oil squeezing cylinder 10. A sliding rod is fixedly installed on the side surface of the piston plate 11. One end of the sliding rod is rotatably connected to a third connecting rod 12. The other end of the third connecting rod 12 is rotatably connected to a driven rod 13. The driven rod 13 is fixedly installed on the lower surface of the transmission gear ring 603, realizing the linkage between lubrication and positioning actions. When the transmission gear ring 603 rotates and drives the arc-shaped positioning insert 601 to unfold, it simultaneously drives the piston plate 11 to squeeze the lubricating oil in the oil storage frame 8 and discharge it from the oil drain hole 9. The fixing action and the lubrication action are integrated, requiring no additional operation or power source, thus improving the practicality of the device.

[0024] Example 3: Reference Figure 8 As shown, the difference between this embodiment and Embodiment 1 is that several settling guide pipes 2 are spliced ​​together and installed. A threaded cylinder 14 is fixedly installed on the inner side wall of the top of the settling guide pipe 2. A connecting cylinder 15 is threadedly connected to the outer surface of the threaded cylinder 14. The connecting cylinder 15 is fixedly installed on the lower surface of the upper settling guide pipe 2. The settling guide pipes 2 are spliced ​​together and installed, and the threaded connection between the threaded cylinder 14 and the connecting cylinder 15 is achieved. This allows the settling guide pipes to be flexibly extended or shortened according to the detection depth, which enhances the adaptability of the device to the monitoring conditions of waste disposal sites at different depths.

[0025] Specifically, refer to Figure 8 As shown, an annular groove is provided on the outer surface of the docking cylinder 15. A retaining ring 16 is slidably connected to the surface of the annular groove. A retaining post 4 is fixedly installed in an annular array on the lower surface of the retaining ring 16. The retaining post 4 is slidably installed through the surface of the docking cylinder 15. A retaining hole adapted to the retaining post 4 is provided on the lower surface of the lower settling conduit 2. A first magnetic block is embedded in the lower surface of the retaining ring 16. A second magnetic block magnetically connected to the first magnetic block is embedded in the inner bottom wall of the annular groove. A snap-fit ​​anti-loosening structure is added on the basis of the threaded connection, so that the retaining ring 16 can automatically maintain the locked state after installation, effectively preventing the settling conduit 2 from loosening due to vibration or external force during use, and improving the reliability and safety of the conduit connection during long-term monitoring.

[0026] Specifically, refer to Figure 1 and Figure 2As shown, a frame is installed on one side of the pipe bottom cover 1. Inside the frame, a storage battery 17 and a controller are placed. A solar panel 18, electrically connected to the storage battery 17, is installed on top of the frame. The controller is electrically connected to a drive motor and a settling magnetic ring 5. By setting up the frame, storage battery 17, controller, and solar panel 18, and electrically connecting the controller to the drive motor and settling magnetic ring 5, the device achieves independent power supply and intelligent control. The solar panel 18 can provide continuous power, which is suitable for outdoor environments without mains power, such as spoil heaps. The controller can perform programmed control of the drive motor and settling magnetic ring 5, which facilitates automated settling monitoring and data acquisition, improving the field applicability and intelligence of the device.

[0027] Working principle: In this invention, according to the required detection depth, multiple settling guide tubes 2 are sequentially spliced ​​together using threaded cylinder 14 and docking cylinder 15. The retaining ring 16 slides downwards, thereby locking the retaining post 4 into place with the retaining hole. The sliding ring 3, along with the settling magnetic ring 5, is then fitted onto the outer surface of the settling guide tube 2. At this point, the slider 608 is initially pressed tightly against the outer surface of the settling guide tube 2 and cannot slide. The sliding ring 3 is fixed to the outer surface of the settling guide tube 2, preventing it from sliding before the settling guide tube 2 is inserted into the borehole. The arc-shaped positioning plate 601 is in its initial state, retracted within the arc-shaped groove. After reaching the predetermined depth, the drive mechanism of the borehole wall positioning assembly 6 is activated, driving the drive motor to rotate the plate. A rotating shaft and a first transmission gear 602 rotate, which drives the transmission gear ring 603 to rotate. The transmission gear ring 603 simultaneously drives the other first transmission gears 602 and the second transmission gear 604 to rotate synchronously. The first transmission gear 602 drives the rotating shaft and the arc-shaped positioning plate 601 to rotate outward. The arc-shaped positioning plate 601 is screwed out from the arc-shaped groove and inserted into the loose waste material on the borehole wall to form radial support. The second transmission gear 604 drives the rotating rod 605 to rotate. The rotating rod 605 drives the slider 608 to slide outward along the guide groove 7 through the first connecting rod 606 and the second connecting rod 607, detaching it from the outer wall of the settling guide 2, thus realizing the separation of the sliding ring 3 from the settling guide 2. During the rotation of the transmission gear ring 603, the driven rod 13 on its lower surface drives the piston plate 11 to slide on one side of the oil squeezing cylinder 10 through the third connecting rod 12, squeezing the lubricating oil in the oil storage frame 8 through the oil discharge hole 9 to the contact surface between the sliding ring 3 and the settling guide 2, ensuring that the sliding ring 3 can slide smoothly down with the waste material during the subsequent settling process without being stuck. After positioning is completed, the bottom cover 1 is installed at the bottom of the settling guide 2 and connected to the ground monitoring equipment. When the waste material settles, the sliding ring 3 and the settling magnetic ring 5 sink together with the surrounding soil and slide down along the settling guide 2. The monitoring equipment obtains the settling data at each depth by sensing the position change of the settling magnetic ring 5. The battery 17 and the solar panel 18 provide long-term power for the drive motor, controller and monitoring equipment.

[0028] The control method of this invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0029] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
