TECHNICAL FIELD
[0001] The application relates to the technical field of road collapse monitoring devices, in particular to a buried road collapse monitoring device. BACKGROUND
[0002] With the acceleration of urbanization, road collapse problems are increasingly prominent, which not only threatens people's life and property safety, but also seriously affects the traffic order of the city and the stable operation of the infrastructure. Road collapse is usually caused by natural or human factors, which leads to the destruction of road structure and forms road surface depression or pit. In order to prevent and reduce the occurrence of such disasters, buried road collapse monitoring devices emerge as the times require, which can monitor the stress change inside the road in real time and evaluate the stability and safety of the road.
[0003] At present, the mainstream technology of buried road collapse monitoring device is to excavate a trench at a specific position of the road, bury the sensor in it, and backfill with concrete. This method can make the sensor stably monitor the internal stress of the road, so as to evaluate the firmness of the road. For example, some technical solutions set anchor structures in the road surface layer and the target soil layer respectively, and connect a pressure-bearing rod between them, so as to judge whether the soil layer is loose by monitoring the stress change of the rod, and realize the early warning of road collapse. In addition, there are technologies that use wireless monitoring devices, which are equipped with a magnetic resistance sensor and a magnetic rod, to monitor the displacement change of the soil under the road in real time, so as to warn the road collapse.
[0004] Although the existing technology has achieved certain results in road collapse monitoring, there are still some problems to be solved. One major problem is that before the concrete solidifies, its fluid state may cause the sensor to move, thereby changing the monitoring position of the sensor and affecting the accuracy of the monitoring data. CONTENT OF THE INVENTION
[0005] The purpose of the present application is to solve the problem that before the concrete solidifies, its fluid state may cause the sensor to move, thereby changing the monitoring position of the sensor and affecting the accuracy of the monitoring data. The present application provides a buried road collapse monitoring device.
[0006] In order to achieve the above purpose, the present application specifically adopts the following technical solutions:
[0007] An embedded road collapse monitoring device includes a base, a rubber cylinder fixedly connected to the top of the base, a connecting seat fixedly connected to the top of the rubber cylinder, a storage cover fixedly connected to the top of the connecting seat, a sensor slidably inserted inside the rubber cylinder, an air supply pipe fixedly connected to one end of the connecting seat, an air valve fixedly connected to the input end of the air supply pipe, an output end of the air supply pipe fixedly communicating with the inside of the air bladder, a wireless transmitter fixedly connected to the top of the storage cover, and a lifting mechanism for driving the sensor to move along the length of the rubber cylinder installed inside the connecting seat.
[0008] By adopting the above technical solution, and by setting up a lifting mechanism in conjunction with a rubber cylinder, sensor, and airbag, it is convenient to input gas into the airbag to form a protective enclosure around the sensor with the rubber cylinder. When the lifting mechanism is activated and the sensor is moved to a suitable position along the length of the rubber cylinder, the changes in internal stress of the concrete are directly transmitted to the sensor through the rubber cylinder and then remotely transmitted to the monitoring terminal via a wireless transmitter. This effectively reduces the impact of concrete flow on the sensor installation position and improves the monitoring accuracy of the device.
[0009] Furthermore, the lifting mechanism includes a first bevel gear rotatably connected to the top of the connecting seat, a lifting screw threaded to one end of the first bevel gear, a second bevel gear rotatably connected to the inside of the connecting seat and meshing with the first bevel gear, a lifting motor fixedly connected to one end of the connecting seat, the output end of the lifting motor fixedly connected to the second bevel gear, and a guide assembly installed inside the storage cover.
[0010] By adopting the above technical solution, and by setting up the guide component to cooperate with bevel gear one and lifting screw, it is convenient to start the lifting motor to drive bevel gear two to mesh with bevel gear one, and drive bevel gear one to drive the lifting screw and sensor to move along the length of the rubber cylinder, thereby effectively improving the practicality of the device.
[0011] Furthermore, the guiding component includes a guiding groove formed inside the storage cover, and a guiding slider is fixedly connected to the top of the lifting screw, with one end of the guiding slider slidably connected inside the guiding groove.
[0012] By adopting the above technical solution, and by setting up the guide groove and guide slider in cooperation, it is convenient for the lifting screw to drive the guide slider to slide along the length direction of the guide groove when the drive bevel gear is threadedly connected to the lifting screw, which further improves the practicality of the device.
[0013] Furthermore, the bottom of the base is provided with a plurality of insertion holes evenly distributed, and a fixed steel fork is inserted into the insertion holes.
[0014] By adopting the above technical solution, and by using the combination of the insertion hole and the fixing steel fork, it is convenient to quickly pre-fix the base when the traction base is placed inside the pit by striking one end of the fixing steel fork through the insertion hole and embedding it into the ground, thereby effectively improving the practicality of the device.
[0015] Furthermore, the sensor has a plurality of ball bearings hinged to a uniform sphere on its periphery, and the ball bearings roll and abut against the rubber cylinder.
[0016] By adopting the above technical solution and setting the ball bearings to work in conjunction with the sensor, the wear between the sensor and the rubber cylinder is effectively reduced, the service life of the device is extended, and the smoothness of the device's operation is improved.
[0017] Furthermore, one end of the storage cover is fixedly connected to a transparent window adapted to the guide slider.
[0018] By adopting the above technical solution and setting a transparent window, it is easy to observe the installation height of the lifting screw inside the storage cover, thereby determining the installation height of the sensor inside the rubber cylinder, which improves the practicality of the device.
[0019] Furthermore, a color-developing ring is fixedly connected to one end of the guide slider, and a scale that matches the color-developing ring is fixedly connected to the outside of the transparent window.
[0020] By adopting the above technical solution and using the color ring and scale together, it is easy to observe the relative position of the color ring and scale through the transparent window, thereby determining the distance the sensor moves along the length of the rubber cylinder, further improving the practicality of the device.
[0021] Furthermore, the surfaces of the base, connecting seat, and storage cover are all coated with an organosilicon waterproof coating.
[0022] By adopting the above technical solution and setting an organosilicon waterproof coating, the corrosion resistance of the device is effectively improved and the service life of the device is extended.
[0023] In summary, this application includes at least one of the following beneficial effects:
[0024] 1. By setting up a lifting mechanism in conjunction with a rubber cylinder, sensor, and airbag, it is easy to input gas into the airbag to form a protective enclosure around the sensor with the rubber cylinder. When the lifting mechanism is activated and the sensor is moved to a suitable position along the length of the rubber cylinder, the changes in internal stress of the concrete are directly transmitted to the sensor through the rubber cylinder and then remotely transmitted to the monitoring terminal via a wireless transmitter. This effectively reduces the impact of concrete flow on the sensor's installation position and improves the monitoring accuracy of the device.

Detailed Implementation
[0031] The following is in conjunction with the appendix Figure 1 —3 provides further detailed description of this application.
[0032] This application discloses an embedded road collapse monitoring device.
[0033] Reference Figure 1 and Figure 2 An embedded road collapse monitoring device includes a base 1, a rubber cylinder 2 fixedly connected to the top of the base 1, a connecting seat 3 fixedly connected to the top of the rubber cylinder 2, a storage cover 4 fixedly connected to the top of the connecting seat 3, a sensor 5 slidably inserted inside the rubber cylinder 2, an air supply pipe 6 fixedly connected to one end of the connecting seat 3, an air valve 7 fixedly connected to the input end of the air supply pipe 6, and an output end of the air supply pipe 6 fixedly connected to the inside of an airbag 8. A wireless transmitter 9 is fixedly connected to the top of the storage cover 4, and a lifting mechanism for driving the sensor 5 to move along the length of the rubber cylinder 2 is installed inside the connecting seat 3.
[0034] The lifting mechanism includes a bevel gear 10 rotatably connected to the top of the connecting seat 3, a lifting screw 11 threadedly connected to one end of the bevel gear 10, a bevel gear 12 rotatably connected to the inside of the connecting seat 3 and meshing with the bevel gear 10, a lifting motor 13 fixedly connected to one end of the connecting seat 3, the output end of the lifting motor 13 fixedly connected to the bevel gear 12, and a guide assembly installed inside the storage cover 4.
[0035] Furthermore, the guiding component includes a guiding groove 14 opened inside the storage cover 4, and a guiding slider 15 is fixedly connected to the top of the lifting screw 11. One end of the guiding slider 15 is slidably connected inside the guiding groove 14.
[0036] In use, first, the air valve 7 is opened to input gas into the airbag 8 through the air supply pipe 6, causing the airbag 8 to inflate and wrap around the outside of the rubber cylinder 2. Then, the air valve 7 is closed. Next, a tunnel is excavated in the corresponding road section according to construction needs, and the base 1 is placed into the tunnel along with the sensor 5. Then, concrete is used for backfilling, so that the concrete wraps around the outside of the airbag 8. When the concrete is vibrated with a vibrator to increase the density, the air valve 7 is opened, causing the concrete to compress the airbag 8 and deform, and fit against the outside of the rubber cylinder 2. At this time, the gas inside the airbag 8 is discharged through the air supply pipe 6. Then, after the concrete sets, it tightly wraps around the outside of the rubber cylinder 2, and the rubber cylinder 2 transmits the changes in road internal stress to the sensor 5 in real time. Then, the sensor 5 transmits the monitoring data remotely to the monitoring terminal through the wireless transmitter 9, so that the sensor 5 can monitor the road internal stress relatively stably.
[0037] Meanwhile, the lifting motor 13 can be started to drive the bevel gear 12 to mesh with the bevel gear 10 and drive the bevel gear 10 to rotate, thereby driving the bevel gear 10 to form a threaded connection with the lifting screw 11, and driving the lifting screw 11 to drive the guide slider 15 to move along the length direction of the guide groove 14. At the same time, the guide slider 15 drives the sensor 5 to slide along the inner wall of the rubber cylinder 2, which facilitates the automatic adjustment of the monitoring depth of the sensor 5, effectively reduces the impact of flowing concrete on the installation position of the sensor 5, and improves the monitoring accuracy of the sensor 5.
[0038] Reference Figure 2 and Figure 3 The bottom of the base 1 has multiple evenly spaced holes 16, and a fixed steel fork 17 is inserted into the hole 16.
[0039] In use, one end of the traction-fixed steel fork 17 is passed through the insertion hole 16 and embedded in the ground, thereby quickly fixing the base 1 to the ground and effectively improving the practicality of the device.
[0040] Reference Figure 1 andFigure 2 The sensor 5 has multiple balls 18 that are uniformly hinged to its outer periphery, and the balls 18 roll and rub against the rubber cylinder 2.
[0041] In use, when the drive sensor 5 moves along the length of the rubber cylinder 2, the sensor 5 causes the ball bearing 18 to roll against the inner side of the rubber cylinder 2, thereby effectively reducing the friction between the sensor 5 and the rubber cylinder 2, reducing wear between them, improving the smoothness of the sensor 5's movement inside the rubber cylinder 2, and extending the service life of the device.
[0042] Reference Figure 1 and Figure 2 One end of the storage cover 4 is fixedly connected to a transparent window 19 that is compatible with the guide slider 15;
[0043] One end of the guide slider 15 is fixedly connected to a color ring 20, and the outer side of the transparent window 19 is fixedly connected to a scale mark 21 that matches the color ring 20.
[0044] In use, when the lifting screw 11 moves along the length of the storage cover 4, it causes the guide slider 15 and the color ring 20 to move along the length of the transparent window 19. The relative position of the color ring 20 and the scale 21 is observed through the transparent window 19, thereby determining the distance that the lifting screw 11 has driven the sensor 5 to move along the length of the storage cover 4, which effectively improves the practicality of the device.
[0045] Reference Figure 1 and Figure 2 The surfaces of the base 1, the connecting seat 3, and the storage cover 4 are all coated with an organic silicone waterproof coating.
[0046] During use, by applying an organic silicone waterproof coating to the surfaces of the base 1, connecting seat 3, and storage cover 4, a waterproof protective layer is formed on the surfaces of the base 1, connecting seat 3, and storage cover 4, which effectively improves the rust resistance of the surfaces of the base 1, connecting seat 3, and storage cover 4 and extends the service life of the base 1, connecting seat 3, and storage cover 4.
[0047] The implementation principle of the buried road collapse monitoring device in this embodiment is as follows: First, the air valve 7 is opened and gas is introduced into the airbag 8 through the air supply pipe 6, causing the airbag 8 to expand and wrap around the outside of the rubber cylinder 2. Then the air valve 7 is closed. Next, a tunnel is excavated in the corresponding road section according to the construction requirements, and the base 1 is placed into the tunnel along with the sensor 5. Then, one end of the traction and fixing steel fork 17 is passed through the insertion hole 16 and embedded in the ground, so that the base 1 is quickly fixed to the ground.
[0048] Then, concrete is used for backfilling, so that the concrete wraps around the outside of the airbag 8. When the concrete is vibrated with a vibrator to increase the density, the air valve 7 is opened, so that the concrete squeezes the airbag 8 to deform and fits against the outside of the rubber cylinder 2. At this time, the gas inside the airbag 8 is discharged through the air supply pipe 6. Then, after the concrete sets, it tightly wraps around the outside of the rubber cylinder 2, and the rubber cylinder 2 transmits the changes in road internal stress to the sensor 5 in real time. Then, the sensor 5 transmits the monitoring data remotely to the monitoring terminal through the wireless transmitter 9, so that the sensor 5 can monitor the road internal stress relatively stably.
[0049] Simultaneously, the lifting motor 13 can be activated to drive the bevel gear 12 to mesh with the bevel gear 10 and drive the bevel gear 10 to rotate, thereby causing the bevel gear 10 to form a threaded connection with the lifting screw 11, and driving the lifting screw 11 to move the guide slider 15 along the length direction of the guide groove 14. At the same time, the guide slider 15 causes the sensor 5 to slide along the inner wall of the rubber cylinder 2, thereby realizing the automatic adjustment of the monitoring depth of the sensor 5 and effectively reducing the impact of flowing concrete on the installation position of the sensor 5.
[0050] Furthermore, when the lifting screw 11 moves along the length of the storage cover 4, it causes the lifting screw 11 to drive the guide slider 15 and the color ring 20 to move along the length of the transparent window 19. The relative position of the color ring 20 and the scale 21 is observed through the transparent window 19, thereby determining the distance that the lifting screw 11 drives the sensor 5 to move along the length of the storage cover 4.
