Description

Technical Field

[0001] The present invention relates to the technical field of dam settlement monitoring in water conservancy projects, and specifically to a real-time monitoring device for dam settlement in water conservancy projects. Background Technique

[0002] The settlement monitoring of water conservancy dams is an important link to ensure the safe operation of dams. Its main purpose is to timely discover potential safety hazards by accurately measuring and analyzing the settlement changes of dams, and to ensure the stability and safety of dams. Multiple monitoring points are selected on many dams to monitor the settlement of water conservancy dams at fixed points. The monitoring points should cover the key parts of the main structure of the dam, such as the dam body, the dam foundation, and the places with complex geological conditions.

[0003] The patent with the publication number CN216308968U discloses a dam settlement monitoring device for water conservancy projects. Aiming at the problems that most of the existing methods for dam settlement monitoring in water conservancy projects are manual data collection, with high manual intensity, low monitoring accuracy, wasting a large amount of manpower and material resources, and being unfavorable to sustainable development, the following scheme is proposed. It includes an outer matrix, a river channel groove is opened at the top of the outer matrix, a dam body is fixedly installed inside the river channel groove, a control box is fixedly installed on the top of the outer matrix, and a monitoring block is fixedly installed on the left side of the control box. The monitoring block is hollow, and the same sliding plate is slidably installed on the left inner wall and the right inner wall of the monitoring block. Compared with the conventional manual monitoring method for dam settlement in water conservancy projects, it has a high degree of automation, reduces the manual intensity, has high monitoring accuracy, reduces the cost of manpower and material resources, and is conducive to the concept of sustainable development.

[0004] Another example is the patent with the publication number CN220170228U, which discloses a dam settlement monitoring device. The transmitting device includes a first mounting seat, and a transmitter is arranged inside the first mounting seat; a first mounting rod is fixedly installed at the bottom of the first mounting seat, a second mounting rod is arranged at the bottom of the first mounting rod, and a first mounting plate is fixedly installed at the bottom of the second mounting rod. This dam settlement monitoring device realizes the installation of the transmitter and the receiver through the cooperation between the first mounting seat and the second mounting seat, realizes the reception and transmission of signals through the cooperation between the transmitter and the receiver, thereby realizing the monitoring of the dam settlement. Through the cooperation between the first mounting plate, the first bolt, the second mounting plate and the second bolt, the first mounting seat and the second mounting seat are installed, thereby realizing the installation and fixation of the transmitter and the receiver, and thus increasing the monitoring of the dam body during settlement.

[0005] For another example, a patent with the publication number CN221649520U discloses a dam settlement monitoring device for water conservancy projects, which includes a base body. A river channel groove is formed inside the base body, and a dam body is fixed inside the river channel groove. A fixing seat is fixed on one side of the upper part of the base body, and an assembly frame is fixed inside the top end of the fixing seat. When the infrared rangefinder is not in the monitoring state, the wiping cotton pad will always fit on the ranging surface of the infrared rangefinder due to the combination of the electric push rod and the connecting block, providing protection for the ranging surface and avoiding the error influence caused by adhesion of sand, dust, etc. to the ranging surface. Secondly, since the dam body is composed of materials such as soil, stone, and sand, through the floating of seeds in the air and the moistening of rainwater, the seeds are likely to grow into grass on the dam body. When it is relatively lush, it may affect the monitoring. Currently, many settlement monitoring devices need to be installed at fixed points for monitoring. However, due to the long overall length of the dam, monitoring devices need to be installed at multiple positions on the dam, resulting in high monitoring costs and limited monitoring coverage. In addition, some radar settlement monitoring devices have a large coverage range, but due to the large number of monitoring points, when settlement is detected at a certain position on the dam, the staff still needs to go to the site for re-inspection in order to formulate a treatment plan. Some existing settlement monitoring devices are not convenient for marking the settlement position of the dam. The staff still needs to use radar positioning to find the settlement position when going to the site, and then re-inspect to confirm whether it is the position, resulting in a large workload.

[0006] In view of the above problems, it is urgent to innovate and design on the basis of the original dam settlement monitoring device for water conservancy projects. Summary of the Invention

[0015] Preferably, the cleaning mechanism includes a brush barrel rotatably installed on the lower steering arm, and the brush barrel is correspondingly arranged at an oblique lower position of the spray head.

[0016] Preferably, a driving turntable is coaxially connected to the brush barrel, a power column is rotatably connected to the lower steering arm, a driven turntable is coaxially connected to the power column, and a belt for transmitting power is sleeved on the driving turntable and the driven turntable.

[0037] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Embodiment 1: Please refer to Figures 1-13, the present invention provides the following technical solution: A real-time monitoring device for the settlement of a hydraulic engineering dam, including an intelligent inspection vehicle 1 that moves around the matrix of the dam to monitor the settlement of the dam. A control box 2 for receiving and transmitting signals and controlling the monitoring is provided on the intelligent inspection vehicle 1. A moving seat 3 is slidably installed on the intelligent inspection vehicle 1. A moving frame 4 is fixedly connected to the moving seat 3. A distance sensor 5 for monitoring the distance from the surface of the dam to analyze the settlement situation is installed on the moving frame 4. A upper steering arm 6 is rotatably connected to the moving frame 4. A lower steering arm 7 is movably connected below the upper steering arm 6. A radar water level gauge 8 for monitoring the water level change in the dam to assist in analyzing the settlement of the dam is fixed on the lower steering arm 7. A rotating mechanism for driving the steering adjustment of the upper steering arm 6 and the lower steering arm 7 is provided on the moving frame 4 and the upper steering arm 6. And a limiting mechanism for assisting the movement and folding of the moving frame 4, the upper steering arm 6 and the lower steering arm 7 is provided on the intelligent inspection vehicle 1.

[0039] The rotating mechanism includes an upper rotating shaft 11 rotatably connected to the moving frame 4. The upper rotating shaft 11 is fixedly connected to the upper steering arm 6. A rotating connecting rod 12 is rotatably connected to the upper steering arm 6. The other end of the rotating connecting rod 12 is rotatably connected to the lower steering arm 7.

[0040] A lower rotating shaft 13 is rotatably connected to the upper steering arm 6. A driving gear 14 is fixedly sleeved on the lower rotating shaft 13. A driven gear 15 is meshed and connected beside the driving gear 14. And the driven gear 15 is fixedly installed on the lower steering arm 7.

[0041] The limiting mechanism includes a lead screw 10 rotatably installed on the intelligent inspection vehicle 1. The moving seat 3 is threadedly sleeved and installed on the outside of the lead screw 10. A support frame 9 for supporting the lower steering arm 7 is fixedly installed on the intelligent inspection vehicle 1.

[0042] The intelligent inspection vehicle 1 can remotely control the moving path on the matrix around the dam, set multiple points to be monitored on the dam surface according to the positions located by radar, and move the intelligent inspection vehicle 1 to different points through radar navigation to monitor the dam settlement in real time. When the intelligent inspection vehicle 1 moves to the corresponding monitoring point, the running motor controls the screw rod 10 to rotate. Under the screw drive, the moving seat 3 sleeved outside the screw rod 10 is engaged to move directionally on the intelligent inspection vehicle 1. The moving seat 3 drives the moving frame 4 to move and expand towards the dam. Then, the motor on the moving frame 4 is run to control the upper rotating shaft 11 to rotate. The upper rotating shaft 11 drives the upper steering arm 6 to rotate and expand on the moving frame 4, keeping the distance sensor 5 on the upper steering arm 6 horizontally corresponding to the position directly above the dam. The motor on the upper steering arm 6 is run to control the lower rotating shaft 13 to rotate. The lower rotating shaft 13 drives the driving gear 14 to rotate. The driving gear 14 is meshed and connected with the driven gear 15. Under the meshing drive, the driven gear 15 and the lower steering arm 7 can be controlled to rotate and expand, so that the radar water level gauge 8 on the lower steering arm 7 is horizontally corresponding to the position above the dam water level. The settlement situation of the dam is monitored and analyzed through the cooperation of the distance sensor 5 and the radar water level gauge 8.

[0043] After monitoring a position of the dam, control the upper steering arm 6 and the lower steering arm 7 to rotate and fold under the moving frame 4, and control the moving frame 4 to move and be received into the interior of the intelligent inspection vehicle 1 by rotating the screw rod 10. At this time, the lower steering arm 7 fits on the inclined plane above the support frame 9. Under the support of the support frame 9, the moving frame 4, the upper steering arm 6 and the lower steering arm 7 can be stably received in the interior of the intelligent inspection vehicle 1, adjusting the center of gravity position of the intelligent inspection vehicle 1 to maintain the stability of the intelligent inspection vehicle 1 moving on the matrix around the dam.

[0044] Embodiment 2: On the basis of Embodiment 1, a marking mechanism is also disclosed, and its specific structure is as follows: A marking mechanism for positioning and marking the dam settlement position for subsequent secondary precise detection is provided on the lower steering arm 7, and a cleaning mechanism for cleaning the soil dust on the dam surface is also provided on the lower steering arm 7.

[0045] The marking mechanism includes a liquid storage tank 16 fixed on the lower steering arm 7. A delivery hose 17 for outputting liquid is connected through the liquid storage tank 16. A negative pressure pump 18 for sucking the liquid in the liquid storage tank 16 under pressure is installed on the delivery hose 17, and a nozzle 19 is installed at the port of the delivery hose 17.

[0046] A fixing rod 20 is fixedly connected to the lower steering arm 7. A sliding frame 21 is slidably connected to the fixing rod 20. The sliding frame 21 is fixedly sleeved outside the nozzle 19.

[0047] The cleaning mechanism includes a brush barrel 22 rotatably installed on the lower steering arm 7. The brush barrel 22 is correspondingly arranged at an inclined lower position of the nozzle 19.

[0048] A driving turntable 23 is coaxially connected to the brush barrel 22, a power column 24 is rotatably connected to the lower steering arm 7, a driven turntable 25 is coaxially connected to the power column 24, and a belt 26 for transmitting power is sleeved on the driving turntable 23 and the driven turntable 25.

[0049] An arc-shaped groove 27 is obliquely formed in the power column 24, a sliding column 28 is engaged and slidably connected in the arc-shaped groove 27, and a sliding ring 29 is fixedly installed outside the sliding column 28; the sliding ring 29 is slidably sleeved outside the power column 24, and is fixedly connected between the sliding ring 29 and the sliding frame 21.

[0050] When it is detected that settlement occurs at a certain point of the dam, mark the position so that the subsequent staff can quickly find the position for re-inspection. Control the upper steering arm 6 and the lower steering arm 7 to rotate, so that the brush barrel 22 on the lower steering arm 7 fits on the surface of the dam. Continue to rotate the upper steering arm 6 and the lower steering arm 7 so that the brush barrel 22 fits on the surface roller of the dam. During the rolling process, the brush barrel 22 can clean the soil dust on the surface of the dam to prepare for spraying marks.

[0051] When the brush barrel 22 rolls while fitting on the surface of the dam, at this time, the spraying direction of the nozzle 19 corresponds to the surface of the dam. Operate the negative pressure pump 18 to suck the liquid inside the liquid storage tank 16, and control the liquid to be conveyed to the nozzle 19 through the delivery hose 17. Finally, the liquid paint is sprayed on the surface of the dam through the nozzle 19, so as to quickly mark the position.

[0052] When the brush barrel 22 rolls while fitting on the surface of the dam, the brush barrel 22 drives the driving turntable 23 to rotate synchronously. The driving turntable 23 drives the driven turntable 25 and the power column 24 to rotate under the drive of the belt 26. When the power column 24 rotates, the sliding column 28 is engaged and moves in the arc-shaped groove 27 in the power column 24. The arc-shaped groove 27 is obliquely and closedly formed outside the power column 24. During the continuous rotation of the power column 24, the sliding column 28 can be controlled to move horizontally back and forth. The sliding column 28 controls the sliding ring 29 to move horizontally back and forth while being sleeved outside the power column 24. The sliding ring 29 is fixedly connected to the sliding frame 21, and it controls the sliding frame 21 to move horizontally back and forth while being sleeved outside the fixed rod 20. The nozzle 19 is fixed on the sliding frame 21, so as to realize that while the brush barrel 22 rolls to clean the surface of the dam, the nozzle 19 can be driven to move horizontally back and forth, expanding the spraying mark range of the nozzle 19, making the mark more prominent and facilitating the staff to quickly find the settlement position of the dam.

For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
