Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0027] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the utility model will be further described in detail below with reference to the drawings and specific embodiments.

[0028] As Figures 1-6As shown, the embodiment provides a long-lasting semi-automatic flow and sediment measurement system that can be remotely monitored, including a base 1, a float 2, a platform 3, a flywheel energy storage system 4, a monitoring system, a radio transmission system, a solar power generation system, and a battery 25. The base 1 is fixed with multiple floats 2 around it, and the platform 3 is fixed on the base 1. The monitoring system includes a flow meter 5 and a sediment monitor 6, both of which are installed on the inner side of the base 1 and are signal connected with the data acquisition module. The radio transmission system includes a radio signal transceiver 7, which is signal connected with the data acquisition module and is installed above the platform 3. The solar power generation system includes a mounting bracket 8 and a solar panel 9, the mounting bracket 8 is fixed on the platform 3, and the solar panel 9 is fixed on the mounting bracket 8. The solar panel 9 is electrically connected with the flywheel energy storage system 4 through a power converter, and the flywheel energy storage system 4 is electrically connected with the monitoring system, the radio transmission system, and the battery 25 through the power converter. The battery 25 is electrically connected with the monitoring system and the radio transmission system.

[0029] In this embodiment, the base 1 is fixed with four floats 2 around it, and the four external floats 2 are evenly distributed along the circumference of the base 1, which protects the equipment and prevents it from being damaged by impact. The height of the float 2 is greater than the height of the base 1, and its bottom protrudes downward from the base 1. When the water level is too low, the float 2 will contact the riverbed first, preventing the base 1 and its connected devices from being damaged by the impact of riverbed sand and stones. The base 1 and the float 2 are made of PE material, which has excellent ductility, flexibility, cold resistance, chemical stability, and high-frequency insulation, providing good protection for the device and preventing it from being damaged by long-term immersion in water.

[0030] The platform 3 is a stainless steel platform, and the mounting bracket 8 is a stainless steel support, preferably made of 316 stainless steel. The two are connected by welding to ensure the firmness and reliability of the structure. The platform 3 is conical, allowing water splashed onto it by the base 1 due to wind waves to flow down the inclined surface due to gravity, preventing water accumulation from damaging the equipment. The mounting bracket 8 is a truncated cone, and four solar panels 9 are arranged around it, slightly inclined upward. During normal operation, the solar panels 9 will fully utilize the light energy in the operating conditions to generate electricity and deliver electrical energy to the flywheel energy storage system.

[0031] The flow meter 5 can use pulse Doppler radar or acoustic Doppler current profiler, or a combination of the two. The sediment monitor 6 uses an infrared sediment monitor. Pulse Doppler radar can determine whether the scanned object is sediment by its movement trajectory, preventing the instrument from misjudging moving aquatic organisms such as fish and shrimp as sediment and causing large errors.

[0032] In this embodiment, the base 1 is fixedly provided with a connecting ring 10 made of aluminum alloy, and the float 2 is connected to the base 1 through a crossbar. The crossbar is made of aluminum alloy and is covered with a dense oxide film to prevent corrosion

[0033] In this embodiment, a high-gain antenna 11 is mounted on the radio signal transceiver 7. The high-gain antenna 11 is a V-band high-gain glass steel base antenna. After processing, the data collected by the radio signal transceiver 7 is converted into encrypted long-wave signals and transmitted to the control center through the V-band high-gain glass steel base antenna, ensuring the safety of data transmission.

[0034] In this embodiment, a water turbine generator 12 is also included, which is installed at the lower end of the base 1 and is electrically connected to the flywheel energy storage system 4 through a power converter. The water turbine generator 12 converts mechanical energy into electrical energy by rotating the water turbine driven by the water flow in the river, and the electrical energy is transmitted to the flywheel energy storage system 4 through independent input wires, effectively extending the endurance of the equipment.

[0035] In this embodiment, the flow velocity meter 5 and the sediment monitor 6 are installed and integrated in one detection module, and four detection modules are evenly distributed on the cylindrical shell 13 in the circumferential direction. The outer side of the cylindrical shell 13 is provided with and fixedly connected to a plexiglass guard plate 14. In the circumferential direction, the four detection modules are staggered with the four floats 2. The four detection modules collect the water flow velocity and sediment content data of the current fault region. The plexiglass guard plate 14 is a 5mm thick annular wear-resistant plexiglass guard plate, which is used to protect the monitoring system from damage caused by friction or collision of sand or gravel, and prolong the service life of the equipment.

[0036] In this embodiment, the mounting bracket 8 is fixedly provided with a heat dissipation aluminum plate 15, and the radio signal transceiver 7 is installed on the heat dissipation aluminum plate 15. The radio signal transceiver 7 is fixedly provided with a connecting rod 16 around it, and is fixedly connected to the outer annular support 17 through the connecting rod 16. The annular support 17 is provided with an anemometer 18, and the anemometer 18 is signal connected to the data acquisition module. The heat dissipation aluminum plate 15 is made of aluminum alloy, which has excellent heat conduction performance, so that the heat generated by the radio signal transceiver 7 can be quickly and efficiently conducted to the outside. At the same time, the radio signal transceiver 7 is provided with a heat dissipation port on the side, which prevents the radio signal transceiver 7 from being damaged due to overheating caused by long-term work. The anemometer 18 can collect real-time wind speed in the working environment, and thus can judge the accuracy of the surface and shallow water flow velocity.

[0037] In this embodiment, the flywheel energy storage system 4 is installed and fixed in the protective cover 19, and the protective cover 19 is fixed on the platform 3. The protective cover 19 is fixedly connected to the platform 3 by welding. The flywheel energy storage system 4 is a conventional device, and its structure is not described here.

[0038] In the embodiment, the ultrasonic bird repeller 20 is arranged on the upper end of the protective cover 19, the output port of the ultrasonic bird repeller 20 is located on the upper end thereof, the rain baffle 21 is arranged above the output port of the ultrasonic bird repeller 20, and the bottom of the ultrasonic bird repeller 20 is provided with a drain port. The output channel of the ultrasonic bird repeller 20 is in a "Z" shape, and the river water splashed by wind and waves can directly flow out through the drain port, so that the river water is prevented from flowing into the device and causing damage to the equipment. There are often flying birds near the river, and any platform close to the water source, especially the water platform, is extremely likely to become the landing point of the flying birds, and even the nesting place of the flying birds. In the device, the ultrasonic bird repeller 20 outputs the ultrasonic wave which makes the birds in a small range feel slightly uncomfortable under the condition of not affecting the local ecological environment, so as to drive away the birds which may affect the monitoring in the current monitoring area, and prevent the flying birds from causing damage to the equipment.

[0039] In the embodiment, the battery compartment 22 is arranged on the platform 3, and the storage battery 25 is arranged in the battery compartment 22. When the power supply of the flywheel energy storage system cannot meet the power demand of the equipment, the storage battery 25 will be used as a backup power supply to join the power supply group to maintain the normal operation of the equipment, effectively prolong the endurance of the equipment, and ensure the stable operation of the equipment.

[0040] In the embodiment, the platform 3 is provided with the plug 23, the base 1 is provided with the socket 24, and the plug 23 is inserted into the socket 24. The platform 3 covers the upper side of the battery compartment 22, so that the battery compartment is prevented from being filled with water.

[0041] The components of the device can be manually transported to the monitoring site for assembly, and then pushed into the river, and the device is fixed to the designated monitoring site by connecting the rope (polyester and aluminum fiber composite rope) with the connecting ring. The device can be used to form a monitoring system by adopting the mode of dispersing multiple devices on the same section or in the same area, so that more accurate and complete data can be obtained.

[0042] The operator can set the device by pressing the keys or the touch screen, such as the measurement time interval, the data acquisition depth range and the like. When a complex situation occurs or special measurement is needed, the remote operator can remotely operate the monitoring device by using the remote control instruction, so that the semi-automatic operation mode is realized, the flexibility of operation is ensured, and the requirement for the professional skills of the on-site operator is reduced.

[0043] When the device is used for monitoring, a crane is not needed, and the operator is not needed to be present for supervision, so that a large amount of manpower and material resources can be saved compared with the traditional lead sinker.

[0044] The device has the characteristics of high modularization and integration, and the parts in each module are convenient to disassemble, so that the equipment maintenance or replacement work in the later period is more convenient.

[0045] Compared with ground-based Doppler velocimeters, this invention has the advantage of accurate data, and the monitoring data is not affected by changes in the gas-liquid interface medium or by the bubble curtain generated during the flow of river water.

[0046] This invention can be used normally even in areas with low signal coverage, and the device has low power consumption. Its installed radio transmission system has a power of only 30W, and using a V-band high-gain fiberglass base antenna, it can stably transmit signals to a control center 45km away in open areas via long waves, and the communication distance is greater than 25km in rugged terrain.

[0047] This invention features floats fixed around the base, allowing the device to change with the water level, thus enabling monitoring of water flow and sediment content even when the water level changes.

[0048] This invention features a long operating range. It incorporates solar panels and a hydroelectric generator, effectively utilizing available clean energy sources in the working environment. Furthermore, the device is equipped with a flywheel energy storage system. The carbon fiber flywheel in this system is lightweight and has an extremely low coefficient of friction with air in a vacuum, resulting in excellent energy storage performance. The energy conversion rate of this flywheel energy storage system is generally higher than 90%. A backup battery pack is installed under the stainless steel platform. These features significantly improve the device's operating range and stability, reducing maintenance frequency and costs.

[0049] This invention features remote real-time monitoring capabilities. Through a remote transmission module and data processing software, it enables real-time remote monitoring and analysis of flow and sediment measurement data, providing timely data support for relevant decision-making.

[0050] This invention features convenient semi-automatic operation. The semi-automatic operation mode combines the flexibility of on-site operation with the convenience of remote control, reducing operational difficulty and improving work efficiency.
