[0001] This utility model relates to the field of roadbed settlement detection technology, specifically a roadbed settlement detection device. Background Technology

[0002] Roadbed settlement can lead to road surface cracking, deformation, and even collapse, seriously threatening driving safety and comfort. In order to detect roadbed settlement in a timely manner and carry out road maintenance, it is necessary to install roadbed settlement detection devices to detect roadbed settlement.

[0003] In the prior art, in order not to occupy the surface space of the roadbed, pressure sensors are installed inside the roadbed to detect roadbed settlement. For example, the roadbed settlement detection device proposed in patent application number "CN202122361446.5" includes an energy supply component, a detection component, a signal transmission component and a microcontroller. The detection component includes a support block, a pressure detection sensor, a protective cover and a fixing component. The pressure sensor in the detection component is located inside the roadbed.

[0004] However, in order to ensure that a portion of the roadbed settlement detection device does not settle along with the roadbed, it is necessary to bury or fix a part of it deep into the rock layer below the roadbed. This means that when the settlement detection device needs to be inspected, maintained or the power supply replaced, all layers of the roadbed need to be completely broken to remove the detection device. This makes it inconvenient to inspect and maintain the electrical equipment in the detection device, as well as to repair the roadbed after it has been broken. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1 and Figure 2 A roadbed settlement detection device includes a settlement plate 1 embedded in the roadbed and a fixing rod 2 fixed to the rock layer below the roadbed. The settlement plate 1 can settle together with the roadbed, and the height of the fixing rod 2 will not change. A protective sleeve 3 is fixedly connected to the top of the settlement plate 1. The protective sleeve 3 is also embedded in the roadbed. The inside of the protective sleeve 3 is a cavity. An installation pipe 4 is provided inside the protective sleeve 3 and above the settlement plate 1. An adjustable pressure rod 5 that can move up and down is provided inside the installation pipe 4.

[0025] like Figure 1 and Figure 2 A protective housing 6 is installed inside the installation tube 4. A pressure sensor 7 is installed at the bottom of the protective housing 6 and above the adjusting rod 5. The top of the adjusting rod 5 and the pressure sensor 7 do not contact each other, so the pressure sensor 7 will not be compressed. An opening is provided at the bottom of the settling plate 1. The top of the fixing rod 2 passes through the settling plate 1 and extends into the interior of the installation tube 4. The top of the fixing rod 2 is located below the adjusting rod 5, and the top of the fixing rod 2 and the bottom of the adjusting rod 5 abut together.

[0026] like Figure 1 and Figure 2 The top of the settling plate 1 is fixedly connected to a threaded sleeve 8, and the bottom of the installation tube 4 is provided with an external thread. The bottom of the installation tube 4 is threadedly connected to the inner surface of the threaded sleeve 8. The installation tube 4 is installed inside the protective sleeve 3, above the settling plate 1.

[0027] like Figure 1 and Figure 2The first limiting ring 401 and the second limiting ring 402 are fixedly connected inside the installation tube 4. The center of the first limiting ring 401 and the second limiting ring 402 are both open, so that the adjusting rod 5 can pass through the first limiting ring 401 and the second limiting ring 402.

[0028] A tension spring 9 is fixedly connected to the top of the first limiting ring 401, and a movable block 10 is fixedly connected to the top of the tension spring 9. The first limiting ring 401 provides support for the tension spring 9 and the movable block 10. The outer surface of the adjusting rod 5 is fixedly connected to the movable block 10. The tension spring 9 is sleeved on the outer surface of the adjusting rod 5 and has a downward pulling force on the movable block 10 and the adjusting rod 5.

[0029] like Figure 2 , Figure 3 and Figure 4 The protective housing 6 houses a power supply 11 and a microcontroller 12 with a wireless communication module. The microcontroller 12 is an existing technology model, STM32C031K6U3. The microcontroller 12 is electrically connected to the pressure sensor 7. When the pressure sensor 7 is pressurized, the microcontroller 12 sends a signal to an external device through its wireless communication module. The power supply 11 is connected to the microcontroller 12 and the pressure sensor 7 through wires to supply power to them. The installation method of the microcontroller 12, the power supply 11, and the pressure sensor 7 is an existing technology and can be disassembled for maintenance.

[0030] like Figure 3 and Figure 4 The top of the protective sleeve 3 is fixedly connected to a bearing sleeve 13. The radius of the bearing sleeve 13 is larger than that of the protective sleeve 3, so that the bottom of the bearing sleeve 13 can be supported by the roadbed, thereby improving the compressive strength of the bearing sleeve 13 and its components. A limit plate 14 is provided inside the bearing sleeve 13. A connecting rod 16 is fixedly connected to the bottom of the limit plate 14. The bottom of the connecting rod 16 is fixedly connected to the protective shell 6. A movable plug 17 is fixedly connected to the outer surface of the connecting rod 16 and inside the installation tube 4. The movable plug 17 can seal the top of the installation tube 4.

[0031] like Figure 3 and Figure 4 The bearing sleeve 13 is provided with a sealing cover 18. The bottom of the sealing cover 18 is provided with an annular groove 181 for accommodating the limiting plate 14. When both the sealing cover 18 and the limiting plate 14 are located inside the bearing sleeve 13, the sealing cover 18 plays an auxiliary positioning role for the limiting plate 14.

[0032] The working principle of the roadbed settlement detection device provided by this utility model is as follows:

[0033] The fixing rod 2 is fixed to the rock layer below the roadbed. The settlement plate 1 and the protective sleeve 3 are pre-embedded inside the roadbed. The installation pipe 4 is threaded to the threaded sleeve 8. Under the action of the tension spring 9 pulling down the movable block 10, the movable block 10 and the adjusting pressure rod 5 can be moved down, and the bottom of the adjusting pressure rod 5 and the top of the fixing rod 2 abut together.

[0034] Then, move the limiting plate 14 down, and through the connecting rod 16, drive the protective housing 6 and the pressure sensor 7 into the installation tube 4. Finally, cover the top layer of the roadbed with concrete and then cover the sealing cover 18 to complete the installation of the roadbed settlement detection device.

[0035] When the roadbed settles, the settlement plate 1 settles accordingly. The settlement plate 1 drives the protective sleeve 3 and the installation pipe 4 to move downwards. The components inside the installation pipe 4 move downwards as well. However, the adjusting pressure rod 5 cannot move downwards due to the resistance of the fixing rod 2. At this time, the adjusting pressure rod 5 will move upwards relative to the installation pipe 4 and squeeze the pressure sensor 7. When the pressure sensor 7 is compressed, the microcontroller 12 sends a signal to the external device through the wireless communication module, indicating that the roadbed has settled.

[0036] By damaging the roadbed surface layer on the sealing cover 18, the sealing cover 18 can be moved upward, and then the limiting plate 14 can be moved upward. The limiting plate 14 drives the protective housing 6 and the pressure sensor 7 to move upward through the connecting rod 16. The pressure sensor 7, power supply 11 and microcontroller 12 can be taken out from inside the roadbed, which facilitates the inspection and maintenance of circuit components and the replacement of power supply 11.

[0037] Compared with related technologies, the roadbed settlement detection device provided by this utility model has the following beneficial effects:

[0038] This invention, by fixing a protective sleeve 3 to the top of the settlement plate 1, can isolate an independent space inside the roadbed. The electrical components for detecting the settlement of the roadbed are all installed inside the protective sleeve 3 in a detachable manner. Only the surface layer of the roadbed needs to be damaged to remove the electrical components for detecting the settlement of the roadbed. There is no need to damage all layers of the roadbed at the same time. This facilitates the replacement of the power supply 11 or the inspection and maintenance of the electrical components, as well as the subsequent repair of the roadbed.

[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 illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
