Description

Technical Field

[0001] The present invention relates to the technical field of level monitoring, and particularly to a level monitoring device and a level monitoring system. Background Art

[0002] As is well known, level monitoring is very important in many fields, especially in ensuring the stability and functionality of equipment and structures. For example, in building construction, ensuring the levelness of concrete structures can prevent cracks from occurring, thereby improving the service life and safety performance of buildings. In the installation of mechanical equipment, accurate level monitoring helps to ensure the normal operation and maintenance of the equipment.

[0003] After retrieval, a patent with the Chinese patent application number CN202410827564.6 discloses a level monitoring device and a level monitoring system, which is generally described as including a monitoring device body. A surveying mechanism and a power mechanism are provided on the monitoring device body. The surveying mechanism includes a surveying wheel and a displacement sensor. One side along the width direction of the measured long strip is the detected surface. The surveying wheel can closely adhere to the detected surface and move along the length direction of the measured long strip. The surveying wheel can slide relative to the monitoring device body along the width direction of the measured long strip. The power mechanism can drive the surveying wheel to move along the length direction of the measured long strip. The displacement sensor is connected to the surveying wheel to collect the displacement data of the surveying wheel. When in use, after installing a blocking grid at the end of the photovoltaic array to be detected, and after confirming that the first purlin meets the installation specifications, place this level monitoring device on the purlin of the photovoltaic support. All the idler wheels clamp the purlin, and the limiting wheel adjusts the contact surface with the purlin. The staff starts this level monitoring device through a remote control. This level monitoring device moves forward. Both the front row of power wheels and the rear row of surveying wheels can move on the non-horizontal purlin. During the movement of the rear row of surveying wheels, the slider of the surveying wheel is connected to the slider of the displacement sensor. When the surveying wheel moves in a non-horizontal state, it drives the slider on the sensor to move. The sensor transmits the data signal of the slider movement to the computer terminal or the mobile terminal through the signal transmission device of this level monitoring device. When this level monitoring device moves to the end of the photovoltaic array, turn off this level monitoring device through the remote control, or stop this level monitoring device by the blocking grid. Compare the data collected by this level monitoring device with the design drawings, and mark the points exceeding the design error. The marked content includes the error number, the specific interval, and which purlin. The staff adjusts the purlin according to the marked content.

[0004] Although the above-mentioned prior art solution can form a level verification and adjustment in cooperation with the purlin, in its operation process, first, it is necessary to adjust the idler wheels to clamp the purlin, and the limiting wheel needs to adjust the contact surface with the purlin. That is, the overall solution needs to match the structure of similar purlins to form corresponding detection operations, with limited detection range and the practicality also needs to be further enhanced.

[0043] It should be further noted that the alternating transmission assembly includes a bottom synchronous gear ring 10, a transmission gear 11, and a transmission thread block 12. The synchronous gear ring 10 is rotatably connected to the bottom end of the lifting bottom shell 4, and the synchronous gear ring 10 meshes with three driving gears 13. Each of the three driving gears 13 is fixedly connected to a bevel gear shaft 14. Each of the three bevel gear shafts 14 meshes with a bevel gear ring 15. The three bevel gear rings 15 are respectively fixedly connected to the three rotating shafts 8. Each of the three bevel gear shafts 14 is rotatably connected to the lifting bottom shell 4. The transmission gear 11 is installed between the lifting bottom shell 4 and the lifting top shell 5 through an active adjustment mechanism, and the transmission gear 11 cooperates with a straight rack 16. The straight rack 16 is fixedly connected to the insertion frame 1. The active adjustment mechanism is connected to an access driving mechanism, and the access driving mechanism is matched with one of the three rotating shafts 8. The transmission thread block 12 is slidably connected between the lifting bottom shell 4 and the lifting top shell 5. The insertion frame 1 is provided with a thread groove 17 that matches the transmission thread block 12. The transmission thread block 12 is connected to the active adjustment mechanism. Through the provision of the alternating transmission assembly, when the lifting bottom shell 4 and the lifting top shell 5 fall relative to the insertion frame 1 under the action of their own gravity, a linkage adjustment of the detection directions of the three laser rangefinders 6 can be formed, so as to achieve continuous and multi-point detection operations. The detection data is relatively rich and the monitoring reliability is good. The active adjustment mechanism includes a moving frame 18. Two sliding connection half-cavities 19 are provided between the lifting bottom shell 4 and the lifting top shell 5. The moving frame 18 is slidably connected between the two sliding connection half-cavities 19, and a double limiting member is provided between the moving frame 18 and the lifting bottom shell 4. The double limiting member includes a fixed rotating connection frame 24 and a moving rotating connection frame 25. The fixed rotating connection frame 24 is rotatably connected to the lifting bottom shell 4. The moving frame 18 is provided with a rotating connection port 26. The moving rotating connection frame 25 is rotatably connected to the rotating connection port 26. A limiting spring 27 is fixedly connected between the fixed rotating connection frame 24 and the moving rotating connection frame 25 to assist in positioning the position of the moving frame 18. That is, when the moving frame 18 approaches the insertion frame 1, the limiting spring 27 enters an extended state, which can realize the auxiliary limit of the state where the moving frame 18 approaches the insertion frame 1. Similarly, when the moving frame 18 moves away from the insertion frame 1, the limiting spring 27 enters another extended state, which can realize the auxiliary limit of the state where the moving frame 18 moves away from the insertion frame 1. A rotating shaft cylinder 20 is rotatably connected inside the moving frame 18. The transmission gear 11 is fixedly connected to the rotating shaft cylinder 20. The top ends of the moving frame 18 and the transmission thread block 12 are both rotatably connected to a transmission rotating column 21. A linkage bar 22 is fixedly connected between the two transmission rotating columns 21, which provides a necessary prerequisite for installing the transmission gear 11 and also for the movement adjustment of the transmission gear 11. Two long strip holes 23 are provided on the lifting top shell 5. The two transmission rotating columns 21 are respectively located in the two long strip holes 23.

[0044] It should be further noted that the driving mechanism includes a conical prism 28. An installation groove 29 is formed in the rotating shaft cylinder 20. The conical prism 28 is slidably connected in the installation groove 29. The conical prism 28 is fixedly connected with a pushing spring 30. The pushing spring 30 is fixedly connected in the installation groove 29. An extension shaft bracket 31 is fixedly connected to a rotating shaft 8 perpendicular to the transmission gear 11. A rib groove 32 is formed in the extension shaft bracket 31. The rib groove 32 matches the conical prism 28. When the conical prism 28 is inserted into the rib groove 32, the rotation of the conical prism 28 can drive the extension shaft bracket 31 to rotate. An external driving member matching the conical prism 28 is installed outside the moving frame 18. The external driving member includes an external ring 33. A rotating rod 34 is fixedly connected to the external ring 33. A rotating hole is formed in the moving frame 18. The rotating rod 34 is rotatably connected in the rotating hole.

A strip connecting frame 37 is connected to the outside of the driving rod 36. A rotating ring 38 is rotatably connected to the strip connecting frame 37. The rotating ring 38 is rotatably connected to the conical prism 28. When it is necessary to adjust the transmission gear 11 to move away from the straight rack 16, first, the conical prism 28 needs to be pulled out of the rib groove 32 so that the side rotation effect between the conical prism 28 and the rib groove 32 fails. The external driving member can provide operational convenience for pulling out the conical prism 28 relative to the rib groove 32. That is, by rotating the external ring 33 to rotate the rotating rod 34, the rotation of the rotating rod 34 drives the vertical rod 35 to rotate. The rotation of the vertical rod 35 drives the driving rod 36 to rotate. The rotation of the driving rod 36 drives the rotating ring 38 to move through the strip connecting frame 37. The movement of the rotating ring 38 drives the conical prism 28 to be pulled out relative to the rib groove 32. Keeping the state where the conical prism 28 is pulled out relative to the rib groove 32 can realize the pulling of the moving frame 18. The movement of the moving frame 18 drives the transmission gear 11 to move away from the straight rack 16.

[0045] A level monitoring system includes a data sending module, a data receiving module, a data calculation module, and a display control module. There are three data sending modules, and the three data sending modules are respectively connected to three laser rangefinders 6. The three data sending modules are both in information conduction with the data receiving module. The data calculation module compares the three groups of data received by the data receiving module, and the data calculation module has a storage function. The display control module integrates and displays the calculation data and conclusions of the data calculation module.

[0046] The laser rangefinder 6 in this embodiment is a conventional device well-known to those skilled in the art purchased on the market. In the present invention, we only use it and do not improve its structure and function. Its setting method, installation method, and electrical connection method can be debugged and operated by those skilled in the art as long as they follow the requirements of its user manual. Therefore, it will not be elaborated here.

[0047] In summary, the working principle of the level monitoring device and the level monitoring system is as follows. When in use, first, the level monitoring device is installed in a matching manner relative to the detection surface to be monitored. During installation, the pointed optical rod 39 is inserted into the detection surface. During the insertion process, it is detected by the level 3 that the insertion frame 1 is in an upright state, that is, the level 3 is in a horizontal state. If it is not convenient to form a destructive insertion on the detection surface, the outer expansion ring 41 is supported on the detection surface. During the support process, an auxiliary support can be formed by an external inclined shim. Similarly, the insertion frame 1 is adjusted to an upright state through the level 3. Then, according to the usage requirements, a detection form in which the transmission thread block 12 is connected to the thread groove 17 and the transmission gear 11 is away from the straight rack 16 or a detection form in which the transmission thread block 12 is away from the thread groove 17 and the transmission gear 11 is engaged with the straight rack 16 is selected. As shown in the appendix Figure 18 When there is a detection requirement for connecting the transmission thread block 12 to the thread groove 17 and separating the transmission gear 11 from the straight rack 16, as shown, it is necessary to pull the transmission gear 11 away from the straight rack 16. That is, by rotating the rotating rod 34 through the external ring 33, the rotation of the rotating rod 34 drives the rotation of the vertical rod 35, the rotation of the vertical rod 35 drives the rotation of the driving rod 36, the rotation of the driving rod 36 drives the movement of the rotating ring 38 through the bar connecting frame 37, the movement of the rotating ring 38 drives the extraction of the tapered prism 28 relative to the groove 32, and the state of the tapered prism 28 being extracted relative to the groove 32 is maintained, so as to realize the movement of the moving frame 18 in the arrow direction shown in the appendix Figure 18 in the pulling direction of the transmission gear 11. The movement of the moving frame 18 drives the transmission gear 11 away from the straight rack 16, so that the meshing transmission effect between the transmission gear 11 and the straight rack 16 fails. After the adjustment is completed, the rotational force applied to the external ring 33 is released. Under the elastic action of the pushing spring 30, the tapered prism 28 will move back to its original position. Since the tapered prism 28 and the groove 32 have formed a movement deviation, the tapered prism 28 moving back to its original position will abut against the end face of the extension shaft frame 31, which can assist in realizing the rotational limit of the extension shaft frame 31, so that all three rotating shafts 8 have rotational limits. Due to the transmission action of the two transmission columns 21 and the linkage bar 22, the movement of the moving frame 18 will drive the movement of the transmission thread block 12, so that the transmission thread block 12 approaches the insertion frame 1 until the transmission thread block 12 forms a thread connection relative to the thread groove 17.

[0048] Further, during the movement of the moving frame 18, the limiting spring 27 will enter the elongation state again via the extreme compression state, so as to achieve the stable relative position of the adjusted moving frame 18. At the same time, the thread action between the transmission thread block 12 and the thread groove 17 also takes effect. The lifting bottom shell 4 is adjusted relative to the insertion frame 1 to raise it to the extreme height relative to the insertion frame 1. Then, three laser rangefinders 6 are turned on at the same time. Next, the acting force on the lifting bottom shell 4 is released. Under the action of the self-gravity of the lifting bottom shell 4, the lifting bottom shell 4 will fall relative to the insertion frame 1. During the falling process, the transmission thread block 12 will perform a spiral motion relative to the insertion frame 1. This spiral motion can be decomposed into a decrease in the vertical height and a rotational motion in the horizontal direction. The motion of the transmission thread block 12 will drive the synchronous revolution of the three rotating shafts 8 through the transmission of the lifting bottom shell 4 and the tangential cylinder 7. The synchronous revolution of the three rotating shafts 8 drives the movement of the three end shell frames 9. The movement of the end shell frame 9 drives the movement of the laser rangefinder 6 inside it. And while the laser rangefinder 6 is moving, a distance detection in the corresponding direction is formed on the supporting detection surface. Due to the arrangement of the synchronous gear ring 10, the driving gear 13, the bevel gear shaft 14, and the bevel gear ring 15, the three rotating shafts 8 will maintain the same posture. Therefore, the angles formed by the three laser rangefinders 6 relative to the detection surface are also the same. At the same time, since the three laser rangefinders 6 always maintain the same height during the movement process, the distances simultaneously detected by the three laser rangefinders 6 are the same value. By comparing the difference situations of the three simultaneously detected data, the levelness of the detection surface can be judged. And since when the detection angles of the laser rangefinders 6 are the same, the lower the height of the laser rangefinder 6, the smaller the detection range. Therefore, during the process of the lifting bottom shell 4 falling relative to the insertion frame 1, the three laser rangefinders 6 can form a distribution of detection points with a spiral trajectory on the detection surface to improve the detection coverage of the detection surface.

[0049] Furthermore, when a detection form in which the transmission thread block 12 is separated from the thread groove 17 and the transmission gear 11 meshes with the straight rack 16 is required, that is, when the external ring 33 is rotated again in the state described in the previous paragraph, the tapered prism 28 is separated from the end face of the extension shaft frame 31 and then the moving frame 18 is pushed close to the insertion frame 1, so that a relative meshing action is re-formed between the transmission gear 11 and the straight rack 16. Then, the rotational force acting on the external ring 33 is released, so that the tapered prism 28 moves back to be inserted into the prism groove 32. After that, the rotation of the transmission gear 11 can realize the rotation of the extension shaft frame 31, and the transmission action between the transmission thread block 12 and the thread groove 17 fails. During this process, the limiting spring 27 will also pass through the state of extreme elastic compression and form a limit on the meshing action between the transmission gear 11 and the straight rack 16. Then, the lifting bottom shell 4 is also raised to the extreme height relative to the insertion frame 1, the three laser rangefinders 6 are turned on, and the lifting force acting on the lifting bottom shell 4 is released, so that the lifting bottom shell 4 falls along the insertion frame 1 under the action of its own gravity, as shown in the appendixFigure 19 As shown, due to the meshing drive between the transmission gear 11 and the straight rack 16, the falling of the transmission gear 11 will cause its own rotation. The rotating transmission gear 11 will drive the rotating shaft cylinder 20 to rotate. The rotation of the rotating shaft cylinder 20 drives the extension shaft bracket 31 to rotate through the tapered prism 28. The rotation of the extension shaft bracket 31 drives the rotating shaft 8 fixedly connected thereto. Since all three drive gears 13 are meshed with the synchronous gear ring 10, the rotation of one of the three drive gears 13 will drive the rotation of the other two drive gears 13, ultimately forming the synchronous rotation of the three bevel gear shafts 14. The synchronous rotation of the three bevel gear shafts 14 will achieve the synchronous rotation of the three bevel gear rings 15. The synchronous rotation of the three bevel gear rings 15 will achieve the synchronous rotation of the three rotating shafts 8, so as to achieve the synchronous movement of the three laser rangefinders 6. Along with the lowering of the height of the transmission gear 11 and the self-rotation of the transmission gear 11, the three laser rangefinders 6 can be synchronously rotated, forming a change in the angle between the laser rangefinder 6 and the detection surface. During this process, the action points of the three laser rangefinders 6 on the detection surface form a linear arrangement, so as to further enrich the positions of the detection points in combination with the detection points of the spiral trajectory in the previous paragraph. The distance data synchronously collected by the three laser rangefinders 6 at each time node are all a set of corresponding data. The smaller the difference between each set of the corresponding three data, the better the flatness of the detection surface. The data detected by the laser rangefinder 6 enters the data calculation module through the conduction of the data sending module and the data receiving module. The data calculation module conducts data comparison and analysis to achieve the judgment of the flatness of the detection surface, and forms the integration and display of the comparison and analysis of multiple sets of detection data through the display control module, so as to facilitate people's reading and analysis.
