Description
Technical Field
[0001] The invention relates to the technical field of reservoir monitoring, and in particular to a reservoir water level safety monitoring and early warning device. Background Art
[0002] Reservoir safety monitoring refers to the continuous observation, measurement and analysis of reservoirs and related facilities through a series of technical means and methods to ensure the safe operation and management of reservoirs. This includes the monitoring of reservoir dams, surrounding environment and internal structures of reservoirs, aiming to prevent and reduce potential safety risks and protect the lives and property of the people. Reservoir safety monitoring covers many aspects, including hydrological data monitoring, environmental data monitoring, structural data monitoring and safety event monitoring. Among the hydrological data monitoring methods, reservoir water level monitoring is an important data for reservoir safety early warning monitoring.
[0003] The early warning monitoring of reservoir water level mainly relies on sensor technology. Among them, the more common float-type water level monitoring and early warning technology uses the principle of float floating and sinking to monitor the water level in real time. The float slides on the conduit using the buoyancy of the reservoir water. The position of the float changes with the water level in the reservoir. A displacement sensor is installed on the float to obtain the position information of the float for monitoring, and an early warning is issued when the water level reaches the upper limit.
[0004] When the existing reservoir water level safety monitoring and early warning device is in use, the water level is located below the float. The conduit below the float is immersed in water for a long time, and the surface will absorb snails and other shellfish. The suction cups on the snails and other shellfish can firmly adhere to the outer wall of the conduit, resulting in the float being blocked and unable to slide down after the water level drops due to the lighter gravity of the float. Then the position information monitored by the displacement sensor on the float will have a large error, and usually requires regular manual cleaning. Summary of the invention
[0005] The technical solution of the present invention aims at the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technologies. Specifically, the purpose of the present invention is to provide a reservoir water level safety monitoring and early warning device to solve the problem proposed in the above background technology that after the water level drops, the float will slide down and will be blocked by shellfish such as snails and other aquatic organisms and cannot drop.
[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a reservoir water level safety monitoring and early warning device, comprising a lower base, a conduit is arranged on the top of the lower base, the top of the conduit is connected to an upper base, a processor is installed on the top of the upper base, a floating block slidably matched with the outer wall of the conduit is provided, a rotating ring is sleeved on the outer wall of the upper end of the floating block, a displacement sensor is installed on the top of the floating block, a floating plate is sleeved on the outer side of the floating block, a guide mechanism is arranged between the floating block and the floating plate, a fixed column is connected on the central axis of the conduit between the lower base and the upper base, and a sealing mechanism is arranged inside the conduit and on the top of the floating plate.
[0007] Preferably, the processor is electrically connected to the displacement sensor, the inner side wall of the rotating ring is provided with an annular protrusion, and the outer wall of the floating block is provided with an annular groove that fits with the annular protrusion.
[0008] Preferably, the floating block and the floating plate are located on the same central axis, and the floating plate is configured as an annular structure.
[0009] Preferably, the guide mechanism includes a guide column arranged on the inner side of the floating plate, the outer wall of the floating block is inclined to open a guide groove that slides with the guide column, and two groups of scrapers are symmetrically arranged at the bottom center of the floating block, and both groups of scrapers are in contact with the outer wall of the catheter.
[0010] Preferably, the sealing mechanism comprises an airbag arranged on the outer wall of the fixed column, the airbag is arranged as a tubular structure, the outer wall of the conduit is evenly provided with air holes leading to the inside, and the top of the floating plate is provided with an inflation and deflation assembly.
[0011] Preferably, the inflation and deflation assembly includes an air cylinder arranged on the top of the floating plate, a connecting plate extending to the top of the air cylinder is arranged on the top of the rotating ring, a piston slidingly matched with the air cylinder is arranged inside the air cylinder, a connecting column is connected between the piston and the connecting plate, a hole groove is arranged at the bottom of the air cylinder, a return spring located on the outside of the connecting column is connected between the air cylinder and the connecting plate, and a hose is connected between the upper end of the airbag and the lower end of the air cylinder.
[0012] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, during the process of water level dropping, the floating block and the floating plate will move down with the water body, and the bottom of the floating block cannot move down after contacting the obstruction, and the water level continues to drop, then the buoyancy of the water body on the floating plate disappears, and the floating plate moves down by gravity, and the floating plate drives the air cylinder to move down, and the air cylinder slides down on the outer wall of the piston, and the reset spring is reset, and the air bag gas in the conduit can be pumped into the air cylinder through the hose, and the outer wall of the air bag shrinks and no longer blocks the air holes on the conduit. Since the shellfish aquatic organisms such as snails use the suction cup to adsorb on the outer wall of the conduit, the air holes in the area covered by the suction cup are not blocked at this time, which can reduce the adsorption force of the suction cup, so that the shellfish aquatic organisms such as snails with smaller adsorption force automatically fall off; In the present invention, if there are still a small amount of snails and other shellfish aquatic organisms on the surface of the conduit blocking the floating block from moving downward, the guide column on the inner side of the floating plate pushes downward in the guide groove while the floating plate descends. Since the guide groove is opened in an inclined arc direction on the outer wall of the floating block and the surrounding angle of the guide groove is 180 degrees, the floating block can be rotated 180 degrees by using the guide groove while the guide column slides, and the floating block is rotated in the rotating ring by using the annular protrusion to slide in the matching annular groove, and the two groups of scrapers symmetrically centered at the bottom of the floating block are synchronously rotated 180 degrees, which can be The outer wall of the conduit at the bottom of the block is scraped in a circle, and the shellfish and aquatic organisms such as snails that have not fallen off can be scraped off. The floating block slides down after being unobstructed. If it is not obstructed, it slides down to the water surface and floats up. If there are still shellfish and aquatic organisms such as snails, the gravity of the floating block is large while sliding down, and the return spring is compressed again. Similarly, the piston fills the gas into the air bag again, and the air bag blocks the air hole until the floating block is blocked. The above process is used to clean the surface of the conduit again, so that the shellfish and aquatic organisms such as snails adsorbed on the outer wall of the conduit can be effectively cleaned off. The present invention can automatically clean snails and other shellfish aquatic organisms on the outer wall of the conduit when the water level changes by utilizing the cleaning process, thereby saving manpower and improving the accuracy of water level monitoring.

[0018] The floating block 5 and the floating plate 7 are located on the same central axis, and the floating plate 7 is configured as an annular structure.
[0019] The guide mechanism includes a guide column 8 arranged on the inner side of the floating plate 7. The outer wall of the floating block 5 is inclined to open a guide groove 9 that slides with the guide column 8. Two groups of scrapers 10 are symmetrically arranged at the bottom center of the floating block 5, and the two groups of scrapers 10 are both in contact with the outer wall of the catheter 2.
[0020] The sealing mechanism includes an air bag 12 arranged on the outer wall of the fixed column 11. The air bag 12 is arranged as a tubular structure. The outer wall of the catheter 2 is evenly provided with air holes 13 leading to the inside. The top of the floating plate 7 is provided with an inflation and deflation assembly.
[0021] The inflation and deflation assembly includes an air cylinder 14 arranged on the top of the floating plate 7, a connecting plate 15 extending to the top of the air cylinder 14 is arranged on the top of the rotating ring 501, a piston 16 slidingly matched with the air cylinder 14 is arranged inside the air cylinder 14, a connecting column 17 is connected between the piston 16 and the connecting plate 15, a hole groove is arranged at the bottom of the air cylinder 14, a return spring 18 located on the outside of the connecting column 17 is connected between the air cylinder 14 and the connecting plate 15, and a hose 19 is connected between the upper end of the airbag 12 and the lower end of the air cylinder 14.
[0022] Working principle: When using the reservoir safety monitoring and early warning device, first, install the device on the dam of the reservoir through the lower base 1, and the floating block 5 and the floating plate 7 float on the water surface by buoyancy. The gravity of the floating block 5 is greater than that of the floating plate 7. Figure 1 As shown, the return spring 18 is in a compressed state, and the elastic force of the return spring 18 is smaller than the buoyancy of the water body on the floating block 5 and the floating plate 7, and the elastic force of the return spring 18 is smaller than the gravity of the floating block 5 and the floating plate 7 when they are not subjected to the buoyancy, and the airbag 12 is in an expanded state, and the outer wall of the airbag 12 blocks the air hole 13 on the catheter 2; When the water level drops, the outer wall of the conduit 2 below the floating block 5 and the floating plate 7 is adsorbed with shellfish such as snails, the floating block 5 and the floating plate 7 will move down with the water, and the bottom of the floating block 5 cannot move down after contacting the obstruction, and the water level continues to drop, then the buoyancy of the water on the floating plate 7 disappears, and the floating plate 7 moves down by gravity, and the floating plate 7 drives the air cylinder 14 to move down, and the air cylinder 14 slides down on the outer wall of the piston 16, and the return spring 18 is reset, and the gas of the air bag 12 in the conduit 2 can be pumped into the air bag 14 through the hose 19, and the outer wall of the air bag 12 shrinks and no longer blocks the pores 13 on the conduit 2, because the shellfish such as snails use the suction cup to adsorb on the outer wall of the conduit 2, the pores 13 in the area covered by the suction cup are not blocked at this time, so that the shellfish such as snails with smaller adsorption force can automatically fall off; If there are still a small amount of snails and other shellfish aquatic organisms on the surface of the conduit 2 blocking the floating block 5 from moving downward, since the adsorption force has been reduced, the floating plate 7 is lowered while the guide column 8 on the inner side of the floating plate 7 is pushed downward in the guide groove 9. Since the guide groove 9 is inclined and opened in the arc direction on the outer wall of the floating block 5, and the surrounding angle of the guide groove 9 is 180°, the guide column 8 slides while the guide groove 9 is used to rotate the floating block 5 180°, and the annular protrusion is used to slide in the matching annular groove to rotate the floating block 5 in the rotating ring 501, and the two sets of scrapers 10 symmetrically centered at the bottom of the floating block 5 are synchronously rotated 180° , the outer wall of the conduit 2 at the bottom of the floating block 5 can be scraped in a circle, and the shellfish such as snails that have not fallen off can be scraped off. The floating block 5 will slide down after it is not blocked. If it is not blocked, it will slide down to the water surface and float. If there are still shellfish such as snails, while sliding down, the gravity of the floating block 5 is large, and the return spring 18 is compressed again. Similarly, the piston 16 fills the gas into the air bag 12 again, and the air bag 12 blocks the air hole 13 until the floating block 5 is blocked. The above process is used to clean the surface of the conduit 2 again, so that the snails and other shellfish adsorbed on the outer wall of the conduit 2 can be effectively cleaned off; The float 5 monitors the water level through the displacement sensor 6 on the top, and sends the information to the data equipment of the reservoir manager through the processor 4 for recording. When the water level rises, since the catheter 2 located in the area above the float 5 and the floating plate 7 is not immersed in water, the surface of the catheter 2 will not absorb snails and other shellfish aquatic organisms. The float 5 can move up with the changes in the liquid level. When the warning water level rises, the reservoir manager receives the water level information and issues a water level warning.
