Description

Technical Field

[0001] The present invention relates to the technical field of slope monitoring, and specifically to a displacement monitoring device for highway rock slopes. Background Art

[0002] With the rapid development of social economy and the acceleration of urbanization, the construction of highways has increased day by day, greatly changing the way of land use. However, this has also led to the frequent occurrence of natural disasters such as landslides, causing serious harm to transportation facilities and mountainous area construction. Especially in the rainy season, phenomena such as highway roadbed landslides and collapses are common, which not only affect the smoothness of traffic but also may pose a threat to the lives and property safety of the people. The structural safety of transportation infrastructure has received increasing attention in recent years. Traditional manual monitoring technologies have been difficult to meet the requirements in terms of timeliness, data volume, and intuitiveness, and new automated monitoring technologies are being steadily developed and promoted; the engineering application technologies involved in automated monitoring technologies are very extensive, including sensor technology, communication technology, Internet technology, and so on.

[0003] For example, a new type of high slope displacement monitoring device disclosed in the Chinese patent authorization publication number: CN 211816491 U can monitor the displacement amount of a high slope through a monitoring cylinder, a displacement monitoring rod, a heavy hammer head, and a scale line, and can monitor the change in the slope of the high slope by setting a cross bar, a sliding rod cylinder, a sliding rod, a rotating seat, a slope measuring plate, a protractor, and a pointer, so that the entire device has the effect of monitoring the change in the slope of the high slope.

[0004] However, there are still some problems when using the above patent. For example, it is necessary for staff to frequently check the scale line to judge the slope displacement data, which is inconvenient to use, and it is easy for stones to roll down on the slope and touch the monitoring rod, affecting the accuracy of the monitoring rod. Summary of the Invention

[0005] The purpose of the present invention is to provide a displacement monitoring device for highway rock slopes to solve the problems raised in the prior art.

[0009] In a preferred embodiment, the solar power supply mechanism includes a support plate fixedly arranged on the outer side wall of the monitoring cylinder. A solar panel is fixedly arranged at the upper end of the support plate. The solar panel is connected with a storage battery inside the installation cavity through an energy conversion device. Protection boxes are arranged at both ends of the solar panel. The solar panel can absorb solar energy and convert it into electric energy to be stored in the storage battery, and the storage battery is used to supply power to the device, while the protection boxes can protect the solar panel.

[0010] In a preferred embodiment, moving blocks are fixedly arranged at the bottom ends of the two protection boxes.

The end of the pulling rope far away from the moving block passes through the side wall at the bottom end of the support plate and is wound around a winding wheel. The winding wheel is fixedly arranged on a rotating shaft. One end of the rotating shaft is connected to the output shaft of a driving motor, and the driving motor is fixedly installed at the bottom end of the support plate. By using the driving motor to drive the rotating shaft to rotate, the pulling rope can be wound by the winding wheel when the rotating shaft rotates.

[0012] In a preferred embodiment, the end of the rotating shaft far away from the driving motor passes through the side wall of the monitoring cylinder and is fixedly connected to a turntable arranged inside the installation cavity. One end of the turntable is rotatably connected to a connecting rod through a pin shaft. One end of the connecting rod is rotatably arranged on the piston. The piston is slidably arranged inside the air inflation cylinder. The rotation of the rotating shaft drives the turntable to rotate. When the turntable rotates, the connecting rod and the piston can move vertically along the air inflation cylinder.

[0013] In a preferred embodiment, a rotating shaft is fixedly arranged at one end of the monitoring sleeve. The monitoring sleeve is rotatably arranged on the outer side wall of the arc-shaped baffle through the rotating shaft. An angle sensor is arranged at one end of the rotating shaft. A piston plate is slidably arranged inside the monitoring sleeve. One end of the piston plate is fixedly arranged with a drill rod connecting rod. One end of the drill rod connecting rod extends out of the monitoring sleeve and is inserted into the slope body. The drill rod connecting rod in the monitoring sleeve extends into the slope body. If the soil layer inside the slope body moves downward, the drill rod connecting rod will move downward driven by the soil layer, causing the monitoring sleeve to rotate. The angle sensor at the end of the monitoring sleeve can judge the sinking distance of the soil layer inside the slope body according to the rotation angle of the monitoring sleeve.

[0014] In a preferred embodiment, an exhaust pipe is arranged at the upper end of the air inflation cylinder. Two branch pipes are arranged on the exhaust pipe. One end of one of the branch pipes is connected to the cavity inside the monitoring sleeve, and one end of the other branch pipe is connected to an air bag. Solenoid valves are arranged on both branch pipes. A pressure valve is arranged at one end of the air bag. And the output end of the air bag is connected to a spray pipe arranged at the upper end of the solar panel through a pipeline. A plurality of nozzles are arranged on the spray pipe. The gas inside the air inflation cylinder can be filled into the monitoring sleeve, enabling the drill rod connecting rod in the monitoring sleeve to move. Moreover, the gas inside the air inflation cylinder can be filled into the air bag, enabling the air bag to store gas with a certain pressure, and then spray it onto the solar panel through the spray pipe, which can blow off the dust on the solar panel and improve the conversion efficiency of the solar panel.

[0015] In a preferred embodiment, an anemometer is provided at the upper end of the monitoring cylinder, and a controller and a wireless transmission module are provided inside the installation cavity. The controller is electrically connected to the laser distance sensor, the angle sensor, the driving motor, and the solenoid valve.

[0016] In a preferred embodiment, card slots are provided on one side of each of the two protection boxes close to each other, and the card slots are matched with the pipeline. The card slots can prevent damage to the pipeline when the two protection boxes approach each other.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. By providing structures such as an arc-shaped baffle, a telescopic baffle, a connecting seat, a protective cover, a monitoring rod, a laser distance sensor, a monitoring sleeve, a drill rod link, and an angle sensor, the present invention uses the laser distance sensor and the angle sensor to monitor the surface displacement of the slope body and the internal soil layer displacement of the slope body respectively, achieving better monitoring effects on the slope body. The arc-shaped baffle, the telescopic baffle, and the protective cover can protect the monitoring rod and the monitoring sleeve, preventing the stones rolling from above the slope body from hitting the monitoring rod and the monitoring sleeve, thereby increasing the service life of the monitoring rod and the monitoring sleeve and improving their detection accuracy.

[0019] 2. By providing structures such as a solar panel, an anemometer, a protection box, a driving motor, a pulling rope, a winding wheel, a moving block, a sliding groove, and a limiting slider, the present invention uses the anemometer to detect the wind force in the environment where the monitoring equipment is located. When the wind force is large, the driving motor is used to drive the winding wheel to rotate, and the winding wheel pulls the two protection boxes closer through the pulling rope, so that the two protection boxes cover the outside of the solar panel, protecting the solar panel and preventing it from being damaged when the wind force is large, reducing equipment maintenance.

[0020] 3. By providing structures such as a turntable, a connecting rod, a piston, an air pump, an airbag, a spray pipe, and a nozzle, the rotation of the driving motor can drive the turntable to rotate, so that the connecting rod drives the piston to move inside the air pump. The air pump can inflate the monitoring sleeve, causing the drill rod link to be pushed out under pressure. Moreover, the air pump can also press air into the airbag, causing the airbag to expand. When the pressure inside the airbag reaches a certain value, the pressure valve opens, and the gas inside the airbag is transported to the spray pipe, and the nozzle at the lower end of the spray pipe blows air onto the solar panel, blowing off the dust on the solar panel. Moreover, there is no need to set up structures such as an air pump, resulting in lower costs. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment: Please refer to Figures 1-7 , the present invention provides a highway rock slope displacement monitoring device, and the technical solution is as follows:

The top end of the monitoring rod 6 is fixedly connected with a ranging slider 9 arranged in an installation cavity 8 inside the monitoring cylinder 5. A laser ranging sensor 10 is arranged directly above the ranging slider 9 inside the installation cavity 8. An arc-shaped baffle 11 is fixedly arranged on one side of the bottom end of the monitoring cylinder 5. A protective cover 12 is fixedly arranged on one side of the arc-shaped baffle 11. A monitoring sleeve 13 is arranged inside the protective cover 12. A solar power supply mechanism is fixedly installed on the side wall of the upper end of the monitoring cylinder 5.

[0032] In a preferred embodiment, a telescopic column 14 is slidably arranged at the upper end of the support column 3. One side of the bottom end of the connecting plate 4 is fixedly connected with the top end of the telescopic column 14. A first locking bolt is arranged at the upper end of the support column 3. A telescopic baffle 15 is slidably arranged at the bottom end of the arc-shaped baffle 11. The bottom end of the telescopic baffle 15 is rotatably arranged on a connecting seat 16. A second locking bolt is arranged on one side of the outer end of the arc-shaped baffle 11. The connecting seat 16 is arranged on the surface of the slope body 1 through bolts. By adjusting the height of the telescopic column 14, the height of the monitoring cylinder 5 can be adjusted, so that the monitoring cylinder 5 can be installed on different slope bodies 1. After the height adjustment is completed, the telescopic column 14 is fixed by using the first locking bolt. And by using the telescopic baffle 15 to adjust the position of the connecting seat 16, the bottom end of the connecting seat 16 is fixed on the slope body 1, which can not only improve the stability of the monitoring cylinder 5, but also protect the monitoring rod 6.

[0033] In a preferred embodiment, the solar power supply mechanism includes a support plate 17 fixedly arranged on the outer side wall of the monitoring cylinder 5. The upper end of the support plate 17 is fixedly provided with a solar panel 18. The solar panel 18 is connected to a storage battery 19 inside the installation cavity 8 through an energy conversion device. Both ends of the solar panel 18 are provided with protection boxes 20. The bottom ends of the two protection boxes 20 are fixedly provided with moving blocks 21. One end of each of the two moving blocks 21 close to each other is provided with a pulling rope 22. The end of the pulling rope 22 away from the moving block 21 passes through the side wall at the bottom end of the support plate 17 and is wound around a winding wheel 23. The winding wheel 23 is fixedly arranged on a rotating shaft 24. One end of the rotating shaft 24 is connected to the output shaft of a driving motor 25, and the driving motor 25 is fixedly installed at the bottom end of the support plate 17. The bottom end of the protection box 20 is fixedly provided with a limiting slider 26. A sliding groove 27 is formed on the upper surface of the support plate 17. The moving block 21 and the limiting slider 26 are slidably arranged in the sliding groove 27. A reset spring 28 is arranged between the two moving blocks 21. A docking block is fixedly arranged on one end side wall of one of the protection boxes 20, and a clamping hole 29 matching the docking block is formed in one end of the other protection box 20. Rubber sealing gaskets are arranged at the ends of the two protection boxes 20.

[0034] During specific use, the solar panel 18 absorbs solar energy and converts the absorbed solar energy into electric energy and stores it in the storage battery 19. The storage battery 19 is used to supply power to the device. If the environment where the monitoring device is located has strong wind, it is easy for large particles to be blown up and fall on the solar panel 18, which is likely to cause damage to the solar panel 18. When the wind is strong, the driving motor 25 drives the rotating shaft 24 and the winding wheel 23 to rotate. When the winding wheel 23 rotates, it can wind the pulling rope 22, so that the pulling rope 22 pulls the moving block 21 to move, thereby making the two protection boxes 20 approach each other until the two protection boxes 20 contact each other. The docking block on the protection box 20 is inserted into the clamping hole 29 on the other protection box. The two protection boxes 20 cover the solar panel 18, which can prevent the blown-up particles from damaging the solar panel 18. When the protection box 20 moves, the limiting slider 26 moves in the sliding groove 27, making the movement effect of the protection box 20 better. When the driving motor 25 rotates in the reverse direction, the winding wheel 23 releases the pulling rope 22, and the two protection boxes 20 move away from each other under the action of the reset spring 18, so that the solar panel 18 is exposed for continued use.

[0035] In a preferred embodiment, one end of the rotating shaft 24 away from the drive motor 25 passes through the side wall of the monitoring cylinder 5 and is fixedly connected to a turntable 30 disposed inside the installation cavity 8. One end of the turntable 30 is rotatably connected to a connecting rod 31 by a pin shaft. One end of the connecting rod 31 is rotatably disposed on a piston 32. The piston 32 is slidably disposed inside an air charging cylinder 33. One end of the monitoring sleeve 13 is fixedly provided with a rotating shaft. The monitoring sleeve 13 is rotatably disposed on the outer side wall of the arc-shaped baffle 11 through the rotating shaft. One end of the rotating shaft is provided with an angle sensor 39. A piston plate 34 is slidably disposed inside the monitoring sleeve 13. One end of the piston plate 34 is fixedly provided with a drill rod link 35. One end of the drill rod link 35 extends out of the monitoring sleeve 13 and is inserted into the slope body 1. The upper end of the air charging cylinder 33 is provided with an exhaust pipe 36. Two branch pipes 37 are provided on the exhaust pipe 36. One end of one of the branch pipes 37 is connected to the cavity inside the monitoring sleeve 13. One end of the other branch pipe 37 is connected to an airbag 38. Solenoid valves are provided on both of the two branch pipes 37. An air outlet is provided on the monitoring sleeve 13 and a solenoid valve is provided at the air outlet. And in order to prevent the gas inside the airbag 38 and the monitoring sleeve 13 from flowing back, check valves are provided inside the branch pipes 37. An air inlet is formed on the side wall of the air charging cylinder 33. Check valves are provided at both the air inlet and the air outlet of the air charging cylinder 33. One end of the airbag 38 is provided with a pressure valve. In order to ensure that enough air enters the air charging cylinder inside the monitoring cylinder, small ventilation holes can be formed on the side wall of the monitoring cylinder 5 and filters are provided at the ventilation holes to prevent external dust from entering the inside of the monitoring cylinder 5. And the output end of the airbag 38 is connected to a spray pipe 40 disposed on the upper end of the solar panel 18 through a pipe 45. And a plurality of nozzles are provided on the spray pipe 40.

[0036] During specific use, when the rotating shaft 24 rotates, it can drive the turntable 30 to rotate. When the turntable 30 rotates, it can drive the piston 32 to move inside the air charging cylinder 33 through the connecting rod 31. The piston 32 can discharge the gas inside the air charging cylinder 33 through the exhaust port and select the gas inside the air charging cylinder 33 to enter the monitoring sleeve 13 or the airbag 38 according to the opening of the solenoid valve. The gas entering the monitoring sleeve 13 pushes the piston plate 34 to move, so that the piston plate 34 pushes the drill rod link 35 into the slope body 1. And the gas entering the airbag 38 causes the airbag to expand. The expanded gas is transported to the spray pipe 40 and is sprayed out by the nozzles on the spray pipe 40.

[0037] In a preferred embodiment, a wind meter 41 is provided at the upper end of the monitoring cylinder 5. A controller 42 and a wireless transmission module 43 are provided inside the installation cavity 8. The controller 42 is electrically connected to the laser ranging sensor 10, the angle sensor 39, the drive motor 25 and the solenoid valve.

[0038] In a preferred embodiment, clamping grooves 44 are provided on one side of each of the two protective boxes 20 close to each other, and the clamping grooves 44 match the pipelines 45.

[0039] Working principle of the present invention:

[0040] During use, the installation base 2 is fixedly installed above the slope body 1, and the monitoring cylinder 5 is placed on the slope of the slope body 1. After the installation of the monitoring cylinder 5 is completed, the telescopic baffle 15 is slid out from the arc-shaped baffle 11, so that the connecting seat 16 at the bottom end of the telescopic baffle 15 is fixedly connected to the slope body 1. Then, the driving motor 25 is turned on, and the driving motor 25 drives the rotating shaft 24 to rotate. When the rotating shaft 24 rotates, it can drive the turntable 30 to rotate. When the turntable 30 rotates, it can drive the piston 32 to move inside the air charging cylinder 33 through the connecting rod 31. The bronchus 37 on the monitoring sleeve 13 is opened, and the gas inside the air charging cylinder 33 enters the monitoring sleeve 13 through the exhaust pipe 36 and the bronchus 37, so that the internal pressure of the monitoring sleeve 13 pushes the piston plate 34 to move, thereby enabling the piston plate 34 to push the drill rod connecting rod 35 into the slope body 1. The monitoring rod 6 contacts the upper surface of the slope body 1 under the gravity of the heavy hammer 7, realizing the installation of the equipment. After the installation is completed, the initial values of the laser distance sensor 10 and the angle sensor 39 are recorded;

[0041] If the upper surface of the slope body 1 is displaced, the monitoring rod 6 moves downward under the drive of the heavy hammer 7. At this time, the ranging slider 9 also moves downward, and the laser distance sensor 10 detects an increase in the distance from the ranging slider 9. Thus, the distance of the surface displacement of the slope body 1 is judged according to the detection data of the laser distance sensor 10. If the soil layer inside the slope body 1 is displaced, the soil layer inside the slope body 1 drives the drill rod connecting rod 35 and the monitoring sleeve 13 to rotate. When the monitoring sleeve 13 rotates, the angle sensor 39 can detect the rotation angle of the monitoring sleeve 13, and the distance of the downward movement of the monitoring sleeve 13 is judged according to the detection data of the angle sensor 39. The laser distance sensor 10 and the angle sensor 39 transmit the detected data to the controller 42, and the controller 42 transmits the data to the remote monitoring center through the wireless transmission module 43, eliminating the need for staff to frequently check the monitoring data;

[0042] During normal use, the solar panel 18 is exposed. The solar panel 18 is used to absorb solar energy and convert the solar energy into electrical energy, which is stored in the storage battery 19. The storage battery 19 is used to supply power to the device. The anemometer 41 is used to monitor the wind force of the environment where the device is located in real time. When the anemometer 41 detects a large wind force, the data is transmitted to the controller 42. The controller 42 controls the driving motor 25 to turn on. After the driving motor 25 is turned on, it can drive the rotating shaft 24 to rotate. When the rotating shaft 24 rotates, the winding wheel 23 can wind the pulling rope 22. The pulling rope 22 pulls the moving block 21 to move, so that the moving block 21 drives the protection box 20 to move, making the two protection boxes 20 approach each other. The docking block at the end of one protection box 20 is inserted into the clamping hole 29 at the end of the other protection box 20, so that the two protection boxes 20 protect the solar panel 18, and can prevent the particles blown up when the wind force is large from hitting the solar panel 18 and causing damage. When the wind force is small, the driving motor 25 rotates in the reverse direction, so that the winding wheel 23 loosens the pulling rope 22. After the protection box 20 loses the pulling action of the pulling rope 22, under the action of the reset spring 28, the two protection boxes 20 move away from each other, so that the solar panel 18 is exposed and the solar panel 18 can continue to be used;

[0043] After the drill rod link 35 is inserted into the slope body 1, the bronchus 37 connected to the monitoring casing 13 is closed, and the bronchus 37 connected to the airbag 38 is opened. When adjusting the position of the protection box 20, the gas inside the inflator 33 is pushed into the airbag 38, so that the airbag 38 expands. When the internal pressure of the airbag 38 reaches the preset value of the pressure valve, the pressure valve opens. The gas inside the airbag 38 is delivered to the air jet pipe 40, and the nozzles on the air jet pipe 40 are used to blow air on the surface of the solar panel 18, which can blow off the dust on the solar panel 18 and improve the conversion efficiency of the solar panel 18. When it is necessary to clean the solar panel 18 regularly, the driving motor 25 can be opened regularly, so that the driving motor 25 rotates forward and backward continuously, so that the airbag 38 is inflated and expanded, and then the solar panel 18 is cleaned by blowing air.
