Technical Field

[0002] Hydrological monitoring equipment is an instrument used to monitor and record important hydrological elements including water level, rainfall, flow rate, flow, water quality, etc. in real time. They are widely used in hydrological monitoring projects in various fields such as small and medium-sized rivers, lakes, reservoirs and groundwater. These equipment play a vital role in water resources management, flood prevention and disaster reduction, water environment protection and water conservancy project operation management, and provide timely and accurate data support for flood control and drought relief, water resources development and utilization, water environment protection and water-related project operation management;

[0003] Existing hydrological monitoring equipment generally adopts a fixed structure with a cantilever design to monitor the flow, flow velocity and water level of the water surface. However, this design requires maintenance personnel to dismantle the entire equipment for maintenance when the flow, flow velocity or water level monitoring function fails, which brings great inconvenience to maintenance work. In addition, current hydrological monitoring equipment mostly uses fixed photovoltaic panels for power supply, but this method has the limitation of low power generation efficiency. Furthermore, the existing rain gauge has a relatively single function and is limited to counting rainfall, but cannot effectively measure snowfall, which is particularly insufficient when a comprehensive assessment of hydrological conditions is required.

[0039] The present invention provides the following embodiments

[0040] Example 1

[0041] The embodiment of the present invention provides a hydrological information monitoring device for a hydropower station, such as Figure 1-5 As shown, it includes: a control box 1, which is installed on a main component 2. The main component 2 drives a rotating hollow rod 24 to rotate through a rotating gear 25. The main component 2 is equipped with a rainfall monitoring component 4, an energy supply component 7, a camera 11 and a water level flow monitoring component 8 from top to bottom;

[0042] The rainfall monitoring component 4 is used to measure the rainfall and snowfall based on the metering structure 5 and the weighing structure 6. The energy supply component 7 realizes automatic tracking of the sun through the hydraulic telescopic rod 1 77 and the hydraulic telescopic rod 2 79. The control box 1 is electrically connected to the rainfall monitoring component 4, the energy supply component 7, the camera 11 and the water level flow monitoring component 8;

[0043] It also includes a water quality monitoring component for monitoring the water quality of the water body in the hydropower station.

[0044] The working principle and beneficial effects of the above technical solution are as follows: the main component 2 is used as a support, on which a control box 1, a rainfall monitoring component 4, an energy supply component 7, a camera 11, a water level flow monitoring component 8 and a water quality monitoring component are mounted. The rainfall monitoring component 4, the energy supply component 7, the camera 11, the water level flow monitoring component 8 and the water quality monitoring component transmit information to the control box respectively. The rainfall monitoring component 4 is used to monitor the rainfall and snowfall of the hydropower station. The energy supply component 7 is used to power the hydrological information monitoring equipment as a whole through photovoltaic power generation. The camera 11 is used to shoot and monitor the water flow of the hydropower station. The water level flow monitoring component 8 is used to monitor the water level and water flow of the hydropower station. The water quality monitoring component is used to monitor the water quality of the hydropower station.

[0045] In the present invention, the main component 2 adopts a nested design, and the rotating hollow rod 24 is driven to rotate by the rotating gear 25, thereby driving the many monitoring devices on the upper part of the main component 2 to rotate together, which is convenient for operators to repair many monitoring devices and avoids the need for operators to disassemble the entire device when repairing many monitoring devices under a fixed structure. The rainfall monitoring component 4 adopts a dual design of tipping bucket metering and weight monitoring, which can collect rainfall in the rainy season and snowfall in the snowy season, thereby realizing precipitation monitoring throughout the year. At the same time, the energy supply component 7 controls the pitch and rotation respectively through the hydraulic telescopic rod 1 77 and the hydraulic telescopic rod 2 79, thereby realizing the tracking of the sun by the photovoltaic panel 71, thereby improving the power generation efficiency of the hydrological monitoring equipment. At the same time, the design of the water quality monitoring component ensures the stability of the water quality in the hydropower station and prevents the decrease in the power generation efficiency of the hydropower station due to eutrophication of the water body.

[0046] Example 2

[0047] On the basis of Example 1, the main body component 2 includes a basic base 21, a hollow vertical pole 22 is installed on the basic base 21, the basic base 21 is fixed to the ground by bolts, a control box 1 is installed on the hollow vertical pole 22, a support seat 23 is fixed inside the hollow vertical pole 22, a rotating hollow rod 24 is rotatably connected to the support seat 23, the rotating hollow rod 24 and the hollow vertical pole 22 rotate relative to each other, a rotating gear 25 is installed at the bottom end of the rotating hollow rod 24, the rotating gear 25 is meshed with a driving gear 26, the driving gear 26 is rotatably connected to a rotating shaft 27, the rotating shaft 27 passes through and is rotatably connected to the hollow vertical pole 22, one end of the rotating shaft 27 is connected to a crank 28, a locking structure 3 is provided on the hollow vertical pole 22, and the locking structure 3 cooperates with the rotating gear 25.

[0048] The locking structure 3 includes a shift block 31, which is slidably connected between the slide rails 32. A compression elastic member 33 is provided between the shift block 31 and the hollow vertical rod 22. The slide rail 32 is fixed on the inner wall of the hollow vertical rod 22. The bottom of the shift block 31 is symmetrically connected to the insertion rod 34. The side of the shift block 31 is connected to the shift rod 35. The shift rod 35 penetrates and is slidably connected to the hollow vertical rod 22. The insertion rod 34 penetrates and is slidably connected to the rotating gear 25.

[0049] The working principle and beneficial effects of the above technical solution are as follows: the basic base 21 is fixed on the ground as a support, and the hollow vertical rod 22 and the support seat 23 on the basic base 21 serve as the base of the rotating hollow rod 24. When the rotating hollow rod 24 needs to be rotated, the lever 35 is pressed down to make the shift block 31 slide downward along the slide rail 32, and the insertion rod 34 is synchronously disengaged from the rotating gear 25, and then the crank 28 is turned to make the driving gear 26 on the rotating shaft 27 rotate, and the driving gear 26 and the rotating gear 25 mesh and rotate with each other, and the rotating gear 25 drives the rotating hollow rod 24 to rotate relative to the hollow vertical rod 22. When the rotating hollow rod 24 does not need to be rotated, the crank 28 is turned to reset the rotating gear 25, and the lever 35 is released. Under the action of the compression elastic member 33, the shift block 31 is reset along the slide rail 32, and the insertion rod 34 is inserted into the rotating gear 25.

[0050] The present invention utilizes the design of the hollow vertical rod 22 and the rotating hollow rod 24 to realize the rotation of the main component 2. The design ensures the support of the main component 2 for many monitoring components through nested combination, prevents the main component 2 from tipping over, and realizes the rotation of the rotating hollow rod 24 at any angle through the engagement of the crank 28 and the driving gear 26 with the rotating gear 25. At the same time, the design of the insertion rod 34 and the shifting block 31 can lock the rotating gear 25 to prevent the hollow vertical rod 22 and the rotating hollow rod 24 from self-rotating due to vibration and other factors, thereby ensuring the stability of the main component 2.

[0051] Example 3

[0052] On the basis of Example 1, the rainfall monitoring component 4 includes a rain gauge 41, which is arranged on a weighing structure 6, which is mounted on a cylinder 42, which is mounted on a bearing platform 43, which is mounted on a rotating hollow rod 24. A filter screen 44 is arranged inside the rain gauge 41, and a temperature control valve 45 is arranged at the water outlet of the rain gauge 41. A receiving funnel 46 is arranged below the water outlet of the rain gauge 41, which is mounted on an upper support frame 47, and an upper tipping bucket 48 is arranged below the receiving funnel 46. The upper tipping bucket 48 is rotatably connected to the upper support frame 47, and the left and right sides of the top of the upper support frame 47 are both threadedly connected to limit studs 49, and the limit studs 49 cooperate with the upper tipping bucket 48. The upper support frame 47 is provided with a water drop outlet 410 on the left and right sides of the upper tipping bucket 48, and a water retaining plate 411 is arranged at the water drop outlet 410, and a metering structure 5 is arranged below the water drop outlet 410.

[0053] The metering structure 5 includes a collecting funnel 51, which is installed on the upper support frame 47. A metering bucket 52 is provided below the water outlet of the collecting funnel 51, and the metering bucket 52 is rotatably connected to the lower support frame 53. A counting bucket 54 is provided below the metering bucket 52, and the counting bucket 54 is rotatably connected to a single-axis frame 55 and the lower support frame 53. The single-axis frame 55 is installed on the cylinder 42. A sweep rod 56 is provided at the center of the counting bucket 54, and a permanent magnet is installed on the top of the sweep rod 56. Drain pipes 57 are provided on the left and right sides of the counting bucket 54. Limiting studs 58 are threadedly connected on the left and right sides of the top of the lower support frame 53. The limiting studs 58 and the metering bucket 52 cooperate with each other. A reed switch 59 is installed in the middle of the lower support frame 53, and the permanent magnet and the reed switch 59 cooperate with each other. Drain ports 510 are symmetrically provided at the bottom of the cylinder 42, and the drain pipes 57 and the drain ports 510 correspond one to one.

[0054] The weighing structure 6 includes support blocks 61, three groups of support blocks 61 are arranged in a ring at the bottom of the rain gauge 41, the support blocks 61 are fixedly connected to the hydraulic support columns 62, the hydraulic support columns 62 are fixedly installed on the V-shaped support rods 63, the V-shaped support rods 63 are installed on the cylinder body 42, and a liquid adding pipe 64 passes through the rain gauge 41, and the liquid adding pipe 64 passes through the cylinder body 42 and is connected to a liquid storage tank 65, which is installed on the cylinder body 42, and a switch valve 66 is provided at the outlet end of the liquid storage tank 65.

[0055] The beneficial effects of the above technical solution are as follows: when it rains, after the rain gauge 41 collects rainwater, the filter 44 in the rain gauge 41 filters the rainwater, and then the rainwater flows out from the water outlet of the rain gauge 41 and falls into the receiving funnel 46. After the receiving funnel 46 collects rainwater, the receiving funnel 46 drains the rainwater into the upper tipping bucket 48. The two sides of the upper tipping bucket 48 receive rainwater in turn. After one side of the upper tipping bucket 48 receives a certain amount of rainwater, the upper tipping bucket 48 will turn over once. After the other side of the upper tipping bucket 48 receives a certain amount of rainwater, the upper tipping bucket 48 will turn over again. The above process is repeated until rainwater is no longer collected. When the upper tipping bucket 48 turns over, the rainwater enters the collecting funnel 51 through the downspout, and falls into the metering tipping bucket 52 below after throttling and stabilizing the flow through the collecting funnel 51. The left and right sides of the metering tipping bucket 52 receive rainwater in turn. When one side of the metering tipping bucket 52 receives 0. When the rainfall is 0.1 mm, the metering bucket 52 will flip once. After the other side of the metering bucket 52 receives 0.1 mm of rainfall, the metering bucket 52 flips again. When the metering bucket 52 flips, rainwater enters the counting bucket 54. The left and right sides of the counting bucket 54 collect rainwater in the metering bucket 52 in turn. After the counting bucket 54 collects 0.1 mm of rainfall, it will flip once. When the counting bucket 54 flips, the permanent magnet on the sweep rod 56 generates an electromagnetic pulse once through the reed switch 59, and the rainwater in the counting bucket 54 is discharged through the drain pipe 57 and the drain port 510. The limit stud 1 49 and the limit stud 2 58 limit the upper bucket 48 and the metering bucket 52 respectively. The flipping angles of the upper bucket 48 and the metering bucket 52 are controlled by adjusting the lengths of the limit stud 1 49 and the limit stud 2 58.

[0056] When snow falls, the temperature control valve 45 at the bottom of the rain gauge 41 is closed, and the switch valve 66 of the liquid storage tank 65 is opened, and the evaporation inhibition liquid and antifreeze liquid in the liquid storage tank 65 flow into the rain gauge 41. The rain gauge 41 collects snow and melts it into water. The support block 61 supports the rain gauge 41. When the rain gauge 41 collects snow, the pressure on the support block 61 changes, and then the pressure of the hydraulic support column 62 changes, so that the weight of the rain gauge 41 changes.

[0057] The present invention utilizes multi-stage turnover to realize the measurement of rainfall. This design can buffer rainwater to the greatest extent, making the flow of rainwater more uniform and reducing the measurement error caused by changes in precipitation intensity. The multi-stage tipping bucket structure actually provides a redundant mechanism. Even if a certain stage of the tipping bucket cannot work normally due to a fault or blockage, the other tipping buckets can still continue to work to ensure the continuity of the measurement. By adjusting the resolution and range of the tipping bucket, the requirements of different users for precipitation measurement accuracy and range can be met. The design of the weighing structure 6 ensures that the statistics of winter snowfall are taken into account. Combined with the design of the hydraulic support column 62, the high sensitivity of the weighing structure 6 is ensured, so that the rainfall monitoring component 4 can meet the precipitation monitoring needs throughout the year.

[0058] Example 4

[0059] On the basis of Example 1, the energy supply component 7 includes a photovoltaic panel 71, which is installed on two groups of trusses 72 by bolts. The trusses 72 are all installed on the main support rod 73. Two ring sleeves 74 are provided on the main support rod 73. The main support rod 73 and the two ring sleeves 74 rotate relative to each other. The two ring sleeves 74 are fixedly connected to the L-shaped linkage rod 75, and the L-shaped linkage rod 75 is rotatably connected to the L-shaped extension rod 76. The long end of the L-shaped linkage rod 75 is hinged to the output end of the hydraulic telescopic rod 1 77, and the hydraulic telescopic rod 1 77 is hinged to the L-shaped extension rod 76. A linkage rod 78 is installed on the main support rod 73, and one end of the linkage rod 78 is hinged to the output end of the hydraulic telescopic rod 2 79, and the hydraulic telescopic rod 2 79 is hinged to the short end of the L-shaped linkage rod 75. The L-shaped extension rod 76 is installed on the rotating hollow rod 24, and a cable 1 710 is connected between the L-shaped extension rod 76 and the rotating hollow rod 24.

[0060] The beneficial effects of the above technical solution are as follows: when the photovoltaic panel 71 tracks the sun, the hydraulic telescopic rod 1 77 is extended and retracted to drive the L-shaped linkage rod 75 to rotate around the L-shaped extension rod 76, so that the truss 72 on the main support rod 73 and the photovoltaic panel 71 are pitched and rotated (i.e., rotated forward and backward), and at the same time, the hydraulic telescopic rod 2 79 is extended and retracted to drive the linkage rod 78 to rotate, and the linkage rod 78 synchronously drives the main support rod 73 to rotate relative to the ring sleeve 74, and the main support rod 73 drives the truss 72 and the photovoltaic panel 71 to rotate left and right, and the L-shaped extension rod 76 fixes the energy supply component 7 on the rotating hollow rod 24, and the inclined cable 1 710 ensures that the connection between the L-shaped extension rod 76 and the rotating hollow rod 24 is stable;

[0061] The present invention utilizes the design of hydraulic telescopic rod 1 77 and hydraulic telescopic rod 2 79 to achieve solar tracking of photovoltaic panel 71. This design enables photovoltaic panel 71 to automatically follow the sun, thereby achieving high-efficiency power generation of photovoltaic panel 71. In addition, the overall structure is relatively simple, stable, and has strong wind resistance.

[0076] Step 1: Oxygen solubility sensor, turbidity sensor, pH sensor, nitrogen and phosphorus content sensor, first acquisition module, second acquisition module and heavy metal sensor are used to calculate the water quality coefficient W of the water body in the hydropower station. Q :

[0077] Where: W Qi is the water quality coefficient of the water body in the hydropower station during the i-th detection, n is the number of detections of the detection pituitary, κ is the water quality compensation coefficient, X pHi is the detection value of the pH sensor during the i-th detection, is the detection value of the nitrogen and phosphorus content sensor during the i-th detection, V Niis the total nitrogen content in the water body at the time of the i-th detection, V Pi is the total phosphorus content in the water body during the i-th detection, V is the volume of the detected water body, O CODi is the detection value of the first acquisition module during the i-th detection, O BODi is the detection value of the second acquisition module during the i-th detection, O Vi is the detection value of the oxygen solubility sensor during the i-th detection, T ui is the detection value of the turbidity sensor during the i-th detection, H mi is the detection value of the heavy metal sensor during the i-th detection;
