Description

Technical Field

[0001] The present invention relates to the technical field of Beidou GNSS positioning, and specifically to a reservoir safety status monitoring system based on Beidou GNSS positioning. Background Art

[0002] A reservoir dam is a hydraulic engineering structure for flood interception, water storage and water flow regulation, and is an important infrastructure for water resource management. After the reservoir is built, it can play roles such as flood control, irrigation, water supply, and aquaculture. However, as a storage space with high potential energy, the reservoir also poses a huge hazard to the life and property safety of the people downstream. Therefore, the safety monitoring of the reservoir dam is of great significance. However, single monitoring cannot meet the daily safety operation requirements, and diversified and systematic monitoring is imminent. Currently, comprehensive elements such as underground deep displacement monitoring, dam body pressure monitoring, dam body displacement, and environmental rainfall monitoring are integrated, and a solar power supply or an NB-IOT low-power system is adopted for time-sharing acquisition. The acquisition frequency and the number of acquisition times in a cycle are adjustable, and data visualization in 3D is displayed, analyzed in real time, and multi-channel early warnings are given, thus integrating a multi-dimensional health and safety monitoring system for the reservoir dam. The surface displacement of the reservoir dam can be monitored through the monitoring system in combination with surface displacement sensors. The monitoring system performs space resection measurement through the navigation and positioning signals sent by Beidou satellite GNSS to determine the three-dimensional coordinates of the ground points to be measured.

[0003] Reservoir monitoring equipment needs to be installed in an open area by the reservoir. Since the soil by the reservoir is moist and suitable for the growth of green plants all year round, and the growth rate of green plants is fast. If the green plants grow too tall, it is easy to block the monitoring vision of the monitoring part. If the height of the monitoring component cannot be adjusted, it is necessary to cut down the blocking green plants or move the monitoring device to another open area. Both treatment methods are relatively troublesome. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a reservoir safety status monitoring system based on Beidou GNSS positioning to solve the problems raised in the above background art. The structure of the present invention is novel. Rotate the scraping rod downward. Through the connection between the scraping rod and the photovoltaic panel, the photovoltaic panel is in a folded state. At this time, the scraping rod should be vertical. As the scraping rod rotates, the tree branches approaching are cut off by the scraping blades on the outer surface of the scraping rod. The fallen leaves are blocked by the blockers at the bottom of the device to prevent accumulation at the bottom of the device and affect heat dissipation. After the part of the top plate moves until it exceeds the position where the leaves grow, then open the photovoltaic panel. The scraping rod will squeeze the approaching tree branches along the periphery to a position away from the photovoltaic panel and the signal source, which will neither affect photovoltaic power generation nor affect the radar signal transmission of GPS.

[0005] To achieve the above object, the present invention is realized by the following technical solutions: A reservoir safety status monitoring system based on Beidou GNSS positioning, including a top plate. A signal source is installed on the top of the top plate. Six groups of photovoltaic panels are rotatably installed equidistantly around the periphery of the signal source on the top of the top plate through rotating shafts. The bottom of the top plate is rotatably installed with a connecting column through a bearing. A base assembly is provided at the bottom of the connecting column. The base assembly includes a mounting seat. Three sliding frames are rotatably installed equidistantly around the periphery of the mounting seat. A support rod is installed inside the sliding frame. The top of the support rod is connected to the connecting column. A control box is fixed on the top of the mounting seat. A monitoring system is installed inside the control box. A cleaning assembly is provided around the periphery of the top plate. The cleaning assembly includes a scraping rod. A scraping rod is provided at the bottom of the back of each photovoltaic panel. A driving assembly is provided at the bottom of the connecting column. The driving assembly includes a connecting disk. The connecting disk is slidably sleeved on the surface of the connecting column. Six second connecting rods are rotatably installed equidistantly on the surface of the connecting disk. The other end of the second connecting rod is rotatably connected to the tail end of the scraping rod through a rotating shaft. A turntable is provided at the bottom of the connecting disk. The turntable is rotatably installed on the outer surface of the connecting column through a bearing. A driving motor is fixed inside the connecting column. The output end of the driving motor inside the connecting column is fixed to the turntable.

[0006] Further, the base assembly further includes foot pads. The outermost ends of the sliding frames are rotatably installed with foot pads through rotating shafts. Plug posts are inserted on the outer surfaces of the foot pads. Sliders are slidably installed inside the sliding frames. The surfaces of the sliders are rotatably connected to the bottoms of the support rods through rotating shafts.

[0007] Further, the top of the support rod is rotatably connected to a fixing ring through a rotating shaft. The fixing ring is fixed to the bottom of the connecting column. A second electric push rod is fixed on the top of the control box. The extending end of the second electric push rod is fixed to the connecting column.

[0008] Further, the cleaning assembly further includes rubber rings. Elastic rubber rings are provided on the outer end surfaces of the scraping rods. Fixing frames are fixed at the positions corresponding to each scraping rod on the rubber rings. The fixing frames are fixedly installed on the surfaces of the scraping rods.

[0009] Further, a first connecting rod is rotatably installed on the top surface of the scraping rod through a rotating shaft. The other end of the first connecting rod is rotatably connected to the photovoltaic panel through a rotating shaft. A triangular plate is fixed at the outer end of the photovoltaic panel.

[0010] Further, the driving assembly further includes a moving plate. A moving plate is slidably inserted through a spring on the surface of the connecting disk at the position corresponding to the second connecting rod. The bottom of the second connecting rod is rotatably connected to the moving plate through a rotating shaft. A first electric push rod is fixed on the bottom of the top plate. The extending end of the first electric push rod is fixed to the connecting disk.

[0011] Further, an inclined block is fixed on the top surface of the moving plate. A plurality of inclined plates are equidistantly fixed on the surface of the receiving end of the first electric push rod at the top of the connecting disk, and the inclined plates correspond to the positions of the inclined blocks, and the inclined blocks can slide along the inclined surfaces of the inclined plates.

[0012] Further, an insertion frame is fixed to the bottom of the moving plate. Vertical plates are equidistantly fixed on the periphery of the turntable, and insertion blocks are fixed to the tops of the vertical plates, and the insertion blocks can be inserted into the interior of the insertion frame.

[0013] Further, a protective net is sleeved on the periphery of the extending end of the second electric push rod, and the bottom of the protective net is fixedly connected to three foot pads.

[0014] Further, scraping blades are equidistantly fixed on the outer surface of the scraping rod.

[0015] Advantages of the present invention:

[0016] 1. The present invention protects the surrounding environment of the control box through the protective net. Since a large amount of fallen leaves will be generated during the movement of the scraping rod, and the fallen leaves are likely to accumulate around the control box due to excessive temperature, the protective net is used to prevent the accumulation of fallen leaves.

[0017] 2. In the present invention, the part where the second connecting rod is connected to the scraping rod will squeeze the photovoltaic panel to rotate upward. The first connecting rod between the photovoltaic panel and the scraping rod will pull the scraping rod to rotate upward until the photovoltaic panel rotates to a vertical state and the scraping rod rotates to a state where the top is inclined outward. Then, during the rising process of the connecting disk casting, the moving plate extends outward, the second connecting rod drives the scraping rod to rotate, the scraping rod rotates along the rotating shaft of the first connecting rod, and the top of the scraping rod changes from tilting outward to tilting inward. The six scraping rods are wrapped around the outside of the photovoltaic panel in a closing pattern. When the driving disk drives the scraping rod to rotate, the scraping blades on the outer surface of the scraping rod cut the surrounding tree branches and leaves. Since the scraping rod and the photovoltaic panel are combined into a conical shape, it is more convenient to penetrate through the dense leaves and will not damage the signal source and the photovoltaic panel. After exceeding the leaf coverage height, the scraping rod and the photovoltaic panel are opened in the original way. During the rotation of the scraping rod, it cooperates with the rubber ring to squeeze the surrounding approaching tree branches and leaves away from the position where the top plate is located, avoiding covering the signal source and the photovoltaic panel.

[0018] 3. The present invention drives the connecting disk to slide along the connecting column through the first electric push rod, rotating the scraping plate upward. During the movement of the connecting disk, the inclined block will contact the inclined surface of the inclined plate. Under the action of the inclined block sliding along the inclined surface of the inclined plate, the moving plate is pushed outwards along the surface of the connecting disk. On the one hand, as the moving plate is pushed outwards, the scraping plate can be rotated into an inwardly folded shape, which is convenient for extending upwards through the dense field of vision. On the other hand, when the moving plate moves outwards to the highest point, the insertion block just inserts into the insertion frame. At this time, the connecting disk completes the docking with the driving disk, and the driving disk is rotated by the motor built in the connecting column, and the scraping rod rotates synchronously, which can conveniently penetrate through the leaf covering layer and cut the dense leaves through the scraping rod.

[0019] 4. The present invention can push the connecting column upward through the second electric push rod to change the height where the signal source is located. At the same time, the fixing ring moves together with the connecting column. The slider at the bottom of the support rod slides along the sliding frame to support the device after it is lifted, maintaining a certain stability. Through the foot pads and the insertion posts, the device can be fixed to the ground near the reservoir in a three-point manner.

[0020] 5. Compared with the prior art, the present invention rotates the scraping rod downward. Through the connection between the scraping rod and the photovoltaic panel, the photovoltaic panel is in a folded state. At this time, the scraping rod should be vertical. As the scraping rod rotates, the tree branches close to it are cut off by the scraping blades on the outer surface. The fallen leaves are blocked by the shielding objects at the bottom of the device to prevent accumulation at the bottom of the device and affect heat dissipation. After the top plate moves to a position exceeding the growth position of the leaves, the photovoltaic panel is then opened, and the scraping rod will squeeze the tree branches close to it away from the positions of the photovoltaic panel and the signal source, which will neither affect photovoltaic power generation nor affect the radar signal transmission of GPS.

[0030] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0031] Please refer to Figures 1 to 8, the present invention provides a technical solution: a reservoir safety status monitoring system based on Beidou GNSS positioning, including a top plate 1. A signal source 11 is installed on the top of the top plate 1. Six groups of photovoltaic panels 12 are rotatably installed equidistantly around the signal source 11 on the top of the top plate 1 through rotating shafts. A connecting column 14 is rotatably installed at the bottom of the top plate 1 through a bearing. A base assembly 5 is provided at the bottom of the connecting column 14. The base assembly 5 includes a mounting seat 51. Three sliding frames 52 are rotatably installed equidistantly around the mounting seat 51. A support rod 56 is installed inside the sliding frame 52.

A cleaning assembly 2 is provided around the top plate 1. The cleaning assembly 2 includes a scraping rod 21. A scraping rod 21 is provided at the bottom of the back of each photovoltaic panel 12. A driving assembly 3 is provided at the bottom of the connecting column 14. The driving assembly 3 includes a connecting disk 31. The connecting disk 31 is slidably sleeved on the surface of the connecting column 14. Six second connecting rods 27 are rotatably installed equidistantly on the surface of the connecting disk 31. The other end of the second connecting rod 27 is rotatably connected to the tail end of the scraping rod 21 through a rotating shaft. A turntable 36 is provided at the bottom of the connecting disk 31. The turntable 36 is rotatably installed on the outer surface of the connecting column 14 through a bearing. A driving motor is fixed inside the connecting column 14. The output end of the driving motor inside the connecting column 14 is fixed to the turntable 36. In this article, the monitoring system includes a deep displacement meter, deep soil pressure, crack sensor, ultrasonic water level, wind speed and direction, pore water meter, strain gauge, rain gauge, deformation collector and communication gateway. The deep displacement meter is used to monitor the change of soil layer pressure inside the dam body. The deep soil pressure is used to monitor the change of soil layer pressure inside the dam body. The crack sensor is used to monitor the cracks in the dam body and mountain body. The ultrasonic water level is used to monitor the change of the water level of the dam body. The wind speed and direction are used to monitor the change of environmental meteorology. The pore water meter is used to monitor the internal state of the dam body. The strain gauge is used to monitor the internal state of the dam body. The rain gauge is used to monitor the change of environmental meteorology. The deformation collector is used to collect the pore water meter. The communication gateway is used to collect and transmit data. The monitoring methods all adopt existing technologies. When using the device, the device is installed on the ground near the reservoir through the base assembly 5. Data is transmitted through the cooperation of the signal source 11 and Beidou GNSS positioning. The photovoltaic panels 12 and the storage battery inside the control box 54 supply power to various electrical components inside the device. After using it for a period of time, when the signal is weak, through the cooperation of the driving assembly 3 and the cleaning assembly 2, after folding and retracting the photovoltaic panels 12, the scraping rod 21 wraps around the top plate 1, and the top plate 1 is pushed upward. The scraping rod 21 rotates synchronously until the position of the signal source 11 exceeds the blocking leaves. The scraping rod 21 clears and pushes away the tree branches and leaves around the signal source 11 to keep the communication smooth.

[0032] In this embodiment, the base assembly 5 further includes a foot pad 53. The outermost end of the sliding frame 52 is rotatably installed with a foot pad 53 through a rotating shaft, and a plug post 57 is inserted on the outer surface of the foot pad 53. A slider 58 is slidably installed inside the sliding frame 52, and the surface of the slider 58 is rotatably connected to the bottom of the support rod 56 through a rotating shaft. The top of the support rod 56 is rotatably connected to a fixing ring 59 through a rotating shaft, and the fixing ring 59 is fixed to the bottom of the connecting column 14. A second electric push rod 55 is fixed on the top of the control box 54, and the extending end of the second electric push rod 55 is fixedly connected to the connecting column 14. The second electric push rod 55 can push the connecting column 14 to move upward, changing the height where the signal source 11 is located. At the same time, the fixing ring 59 moves together with the connecting column 14. The slider 58 at the bottom of the support rod 56 slides along the sliding frame 52 to support the device after it is raised, maintaining a certain stability. Through the foot pad 53 and the plug post 57, the device can be fixed to the ground near the reservoir in a three-point manner.

[0033] In this embodiment, the driving assembly 3 further includes a moving plate 32. A moving plate 32 is slidably inserted through a spring on the surface of the connecting disk 31 corresponding to the position of the second connecting rod 27, and the bottom of the second connecting rod 27 is rotatably connected to the moving plate 32 through a rotating shaft. A first electric push rod 25 is fixed to the bottom of the top plate 1, and the extending end of the first electric push rod 25 is fixedly connected to the connecting disk 31. An inclined block 33 is fixed on the top surface of the moving plate 32. A plurality of inclined plates 35 are equidistantly fixed on the surface of the receiving end of the first electric push rod 25 above the connecting disk 31, and the inclined plates 35 correspond to the position of the inclined block 33. The inclined block 33 can slide along the inclined surface of the inclined plate 35. The bottom of the moving plate 32 is fixed with an insertion frame 34. Vertical plates 37 are equidistantly fixed on the periphery of the turntable 36, and an insertion block 38 is fixed to the top of the vertical plate 37. The insertion block 38 can be inserted into the insertion frame 34. The first electric push rod 25 drives the connecting disk 31 to slide along the connecting column 14, turning the scraping plate upward. During the movement of the connecting disk 31, the inclined block 33 will contact the inclined surface of the inclined plate 35. Under the action of the inclined block 33 sliding along the inclined surface of the inclined plate 35, the moving plate 32 is pushed outwards along the surface of the connecting disk 31. This structure has two functions. On the one hand, as the moving plate 32 is pushed outwards, the scraping plate can be turned into a folded shape inward, so as to facilitate upward extension through the dense field of vision. On the other hand, when the moving plate 32 moves outwards to the highest point, the insertion block 38 just inserts into the insertion frame 34. At this time, the connecting disk 31 completes the docking with the driving disk. The driving disk is driven to rotate by the motor built in the connecting column 14, and the scraping rod 21 rotates synchronously, which can facilitate passing through the leaf covering layer and cutting the dense leaves by the scraping rod 21. In this part of the content, the driving motor located at the bottom of the connecting column 14 is not shown in the figure. In fact, the installation position of the driving motor is directly connected to the driving disk inside the fixing ring 59 connected to the support rod 56 and does not drive the connecting column 14 to rotate.

[0034] In this embodiment, the cleaning component 2 further includes a rubber ring 24. An elastic rubber ring 24 is provided on the outer end surface of the scraping rod 21, and a fixing frame 26 is fixed at the position of each scraping rod 21 corresponding to the rubber ring 24. The fixing frame 26 is fixedly installed on the surface of the scraping rod 21. A first connecting rod 23 is rotatably installed on the top surface of the scraping rod 21 through a rotating shaft, and the other end of the first connecting rod 23 is rotatably connected to the photovoltaic panel 12 through a rotating shaft. A triangular plate 13 is fixed at the outer end of the photovoltaic panel 12. Scraping blades 22 are equidistantly fixed on the outer surface of the scraping rod 21. During the upward movement of the connecting disk 31, the second connecting rod 27 will push the scraping rod 21 to rotate the scraping rod 21 and the photovoltaic panel 12 upward together. During this process, the part where the second connecting rod 27 is connected to the scraping rod 21 will squeeze the photovoltaic panel 12 to rotate upward, and the first connecting rod 23 between the photovoltaic panel 12 and the scraping rod 21 will pull the scraping rod 21 to rotate upward until the photovoltaic panel 12 rotates to a vertical state and the scraping rod 21 rotates to a state where the top is inclined outward. Then, during the process of the connecting disk 31 casting and rising, the moving plate 32 extends outward, the second connecting rod 27 drives the scraping rod 21 to rotate, the scraping rod 21 rotates along the rotating shaft of the first connecting rod 23, and the top of the scraping rod 21 changes from facing outward to facing inward. The six scraping rods 21 are wrapped around the outside of the photovoltaic panel 12 in a closed manner. When the driving disk drives the scraping rod 21 to rotate, the scraping blades 22 on the outer surface of the scraping rod 21 cut the surrounding tree branches and leaves. Because the scraping rod 21 and the photovoltaic panel 12 are combined into a conical shape, it is more convenient to penetrate through the dense leaves and will not damage the signal source 11 and the photovoltaic panel 12. After exceeding the leaf coverage height, the scraping rod 21 and the photovoltaic panel 12 are opened in the original manner. During the rotation of the scraping rod 21, it cooperates with the rubber ring 24 to squeeze the surrounding approaching tree branches and leaves away from the position of the top plate 1, preventing them from covering the signal source 11 and the photovoltaic panel 12.

[0035] In this embodiment, a protective net 4 is sleeved on the periphery of the extended end of the second electric push rod 55, and the bottom of the protective net 4 is fixedly connected to the three foot pads 53. The main function of the protective net 4 is to protect the surrounding environment of the control box 54. Because a large amount of fallen leaves will be generated during the movement of the scraping rod 21, and the fallen leaves are likely to cause problems due to excessive temperature when piled up around the control box 54, the protective net 4 is used to prevent the accumulation of fallen leaves.

[0036] When using the device, the second electric push rod 55 can be used to push the connecting column 14 upward to change the height of the signal source 11. At the same time, the fixed ring 59 moves together with the connecting column 14, and the slider 58 at the bottom of the support rod 56 slides along the sliding frame 52 to support the device after it is raised, maintaining a certain stability. Through the foot pad 53 and the plug post 57, the device can be fixed to the ground near the reservoir in a three-point manner. Data is transmitted through the cooperation of the signal source 11 and the Beidou GNSS positioning. The photovoltaic panel 12 and the battery inside the control box 54 supply power to various electrical components in the device. After using it for a period of time, when the signal is weak, the first electric push rod 25 drives the connecting plate 31 to slide along the connecting column 14, and the scraper is rotated upward. During the movement of the connecting plate 31, the inclined block 33 will contact the inclined surface of the inclined plate 35. Under the action of the inclined block 33 sliding along the inclined surface of the inclined plate 35, the moving plate 32 is pushed outwards along the surface of the connecting plate 31. This structure has two functions. On the one hand, as the moving plate 32 is pushed outwards, the scraper can be rotated into an inward-folded shape, which is convenient for extending upwards through the dense field of vision. On the other hand, when the moving plate 32 moves outwards to the highest point, the plug block 38 just inserts into the plug frame 34. At this time, the connecting plate 31 completes the docking with the driving disk. The driving disk is driven to rotate by the motor built in the connecting column 14, and the scraping rod 21 rotates synchronously, which is convenient for passing through the leaf covering layer, and the dense leaves can be cut by the scraping rod 21. During the upward movement of the connecting plate 31, the second connecting rod 27 will push the scraping rod 21 to rotate the scraping rod 21 and the photovoltaic panel 12 upwards together. During this process, the part where the second connecting rod 27 is connected to the scraping rod 21 will squeeze the photovoltaic panel 12 to rotate upwards, and the first connecting rod 23 between the photovoltaic panel 12 and the scraping rod 21 will pull the scraping rod 21 to rotate upwards until the photovoltaic panel 12 rotates into a vertical shape and the scraping rod 21 rotates into a shape with the top inclined outwards. Then, during the process of the connecting plate 31 being raised, through the outward extension of the moving plate 32, the second connecting rod 27 drives the scraping rod 21 to rotate, and the scraping rod 21 rotates along the rotating shaft of the first connecting rod 23. The top of the scraping rod 21 changes from tilting outwards to tilting inwards. The six groups of scraping rods 21 are wrapped around the outside of the photovoltaic panel 12 in a closed manner. When the driving disk drives the scraping rod 21 to rotate, the tree branches and leaves around are cut by the scraping blades 22 on the outer surface of the scraping rod 21. Because the scraping rod 21 and the photovoltaic panel 12 are combined into a conical shape, it is more convenient to pass through the dense leaves and will not damage the signal source 11 and the photovoltaic panel 12. After exceeding the leaf covering height, the scraping rod 21 and the photovoltaic panel 12 are opened in the original way. During the rotation of the scraping rod 21, it cooperates with the rubber ring 24 to squeeze the surrounding approaching tree branches and leaves away from the position of the top plate 1, preventing them from covering the signal source 11 and the photovoltaic panel 12. The main function of the protective net 4 is to protect the surrounding environment of the control box 54. Because a lot of fallen leaves will be generated during the movement of the scraping rod 21, and the fallen leaves accumulating around the control box 54 are likely to cause problems due to excessive temperature, so the protective net 4 is used to prevent the accumulation of fallen leaves.

[0037] The foregoing has shown and described the basic principles, main features and advantages of the present invention. For a person skilled in the art, it is obvious that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and without departing from the spirit or basic features of the present invention, the present invention can be implemented in other specific forms.

This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
