[0002] A pumped-storage hydropower station is a special type of hydropower station, also known as a storage hydropower station. Its working principle is mainly to use the electric energy when the power load is low to pump water from the lower reservoir to the upper reservoir for energy storage, and then release the water to the lower reservoir for power generation during the peak period of power load.

[0003] The water level monitoring device of a pumped storage hydropower station is a device specifically used to monitor and record the water level changes of a hydropower station in real time. This device usually consists of a water level sensor, a data acquisition system, data processing software, and corresponding transmission and display equipment.

[0004] Currently available water level monitoring devices cannot flexibly adjust the angle of the radar water level meter according to actual needs, making it unable to adapt to different monitoring environments and conditions, and at the same time cannot expand the monitoring range of the radar water level meter, thereby reducing the accuracy and reliability of the measurement. Utility Model Content

[0005] The utility model aims to solve the shortcomings of the prior art that the angle of the radar water level meter cannot be adjusted, so that it cannot adapt to different monitoring environments and expand the monitoring range, resulting in reduced measurement accuracy and reliability, and proposes a water level monitoring device.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A water level monitoring device, comprising:

[0008] A base, wherein a fixing column is fixedly arranged on the top of the base, a turntable is rotatably arranged on the top of the fixing column, a fixing rod is fixedly arranged on one side of the turntable, and a radar water level gauge is fixedly arranged on one end of the fixing rod;

[0009] An adjusting component is arranged on the fixed column and is used to adjust the position angle monitored by the radar water level meter;

[0010] The limiting component is arranged on the adjusting component and is used to lock the position of the adjusting component.

[0011] In one possible design, the adjusting assembly includes a rotating rod rotatably arranged inside a fixed column, the top of the rotating rod is fixedly connected to the turntable, the outside of the fixed column is located below the turntable and is rotatably provided with a rotating ring, one side of the rotating ring is fixedly provided with a support rod, one end of the support rod is fixedly connected to the fixed rod, the outside of the rotating rod is located inside the fixed column and is fixedly provided with a driven bevel gear, the inside of the fixed column is located below the driven bevel gear and is provided with an active bevel gear, one side of the active bevel gear is fixedly provided with a rotating shaft, one side of the active bevel gear is fixedly provided with a connecting block, one end of the rotating shaft rotates and passes through the interior of the fixed column and passes through the connecting block to extend to the outside, and one end of the rotating shaft located outside the connecting block is fixedly provided with a hand wheel, and the active bevel gear is meshed with the active bevel gear for transmission.

[0012] In a possible design, the limit assembly includes a positioning plate slidably arranged on a rotating shaft between the connecting block and the hand-turned wheel, a limit block fixedly arranged on the rotating shaft outside the connecting block, a sliding groove matched with the limit block is provided on the positioning plate, a plurality of positioning pins are fixedly arranged in a ring shape on one side of the positioning plate close to the connecting block, and a plurality of positioning holes are provided in a ring shape on one side of the connecting block close to the positioning plate, and the positioning holes are matched with the positioning pins and can be detached and inserted.

[0013] In a possible design, two support frames are symmetrically fixedly arranged on the outside of the fixing column, and solar panels are fixedly arranged on the sides of the two support frames that are away from each other.

[0014] In a possible design, a lightning rod is fixedly disposed on the top of the fixed column.

[0015] In a possible design, a mounting bracket is fixedly provided on one side of the fixing column, and an audible and visual alarm is fixedly provided on the top of the mounting bracket.

[0016] In a possible design, an electric control box is fixedly mounted on one side of the fixing column.

[0017] In the present application, when starting to use, first install the device through the base at the place where the water level needs to be monitored, and then rotate the hand wheel. When the hand wheel rotates, the active bevel gear is driven to rotate synchronously through the rotating shaft. When the active bevel gear rotates, it drives the driven bevel gear meshing with it to rotate. When the driven bevel gear rotates, it drives the rotating rod to rotate synchronously. When the rotating rod rotates, it drives the turntable fixed to it to rotate at the top of the fixed column. When the turntable rotates, it drives the fixed rod to rotate. When the fixed rod rotates, it drives the support rod to rotate on the swivel. At the same time, when the fixed rod rotates, the radar water level meter rotates synchronously until the radar water level meter is rotated to be above the water surface. Then slide the positioning plate, and the positioning plate moves on the rotating shaft toward the direction of the connecting block until the positioning pin on the positioning plate is inserted into the positioning hole on the connecting block to complete the insertion. The position of the rotating shaft is limited by the slide groove on the positioning plate and the limit block on the rotating shaft. When the position of the rotating shaft is limited, the position of the radar water level meter is locked. When the position of the radar water level meter needs to be adjusted again, according to the above operation, first unlock the position limit of the rotating shaft, and then rotate the hand wheel to adjust the radar water level. The position of the meter is adjusted, and then the device is powered on. At this time, the radar water level meter works. The radar water level meter transmits microwave pulses through the antenna. The pulses propagate in space at the speed of light. When the microwave pulses encounter the water surface, part of the energy will be reflected back by the water surface, and the other part will be absorbed by the water body. The radar water level meter receives the reflected microwave pulses and measures the time interval from transmission to reception, thereby calculating the distance between the transmitted pulse and the water surface. The running time of the radar pulse signal from transmission to reception is proportional to the distance from the probe to the surface of the medium, that is: \[D=\frac{v\timest}{2}\] where t is the time interval from pulse transmission to reception, and v is the propagation speed of electromagnetic waves, usually 3×10^8 meters / second, so that the calculated water level is transmitted to the electric control box through a signal. When the water level is higher than the preset value, the electric control box sends the signal to the monitoring center and the sound and light alarm respectively. The monitoring center can record the data and issue an early warning. The sound and light alarm can emit sound and flash alarms, thereby reminding nearby staff to come and check, so as to facilitate timely understanding of the water level.

[0018] The utility model has the following beneficial effects:

[0019] In the utility model, by setting the adjustment component, the hand wheel is turned to drive the active bevel gear to rotate, thereby driving the driven bevel gear and the rotating rod to rotate, so as to realize the flexible adjustment of the angle of the turntable and the radar water level meter, and adapt to different monitoring environments and conditions, realize the change of the fan-shaped coverage range of its beam, thereby expanding the monitoring range of the radar water level meter, enabling it to cover a wider water area, and then more comprehensively understand the change of the water level, and improve the accuracy and reliability of the measurement;

[0020] In the utility model, by setting the limit assembly and sliding the positioning plate, the positioning pin is inserted into the positioning hole to achieve the position locking of the adjustment assembly, thereby ensuring the stability of the measurement position of the radar water level meter, helping to reduce the damage or displacement of the device due to environmental factors (such as wind force) or external forces, thereby enhancing the safety of the equipment and improving the stability and accuracy of the measurement;

[0021] The utility model adjusts the setting of the components so that the staff can flexibly adjust the angle of the radar water level meter according to actual needs, so that it can adapt to different monitoring environments and conditions. At the same time, it can change the fan-shaped coverage range of its beam, expand the monitoring range of the radar water level meter, thereby more comprehensively understanding the changes in water level and improving the accuracy and reliability of measurement.
