Description

Technical Field

[0001] This utility model relates to an ecological suppression device for ineffective evaporation in reservoirs of pumped storage power stations, belonging to the field of pumped storage technology. Background Technology

[0002] A pumped-storage hydroelectric power station is a hydroelectric power station that uses electricity generated during periods of low electricity load to pump water into an upper reservoir and then releases the water into a lower reservoir to generate electricity during periods of high electricity load. It is also known as a pumped-storage hydroelectric power station. It can convert excess electricity generated during periods of low grid load into high-value electricity generated during periods of high grid load. It is also suitable for frequency and phase regulation, stabilizing the frequency and voltage of the power system, and serves as a backup in case of emergencies. Furthermore, it can improve the efficiency of thermal and nuclear power plants within the system.

[0003] Located at the junction of eastern and western my country, the area has sparse vegetation, frequent sandstorms, and an extremely dry climate. Due to the geographical location and topography of the basin, which is a valley between two mountains, it experiences prevailing northwest and southeast winds. The average annual evaporation reaches 1805.1 mm, with an average relative humidity of 42%. The prevailing northwest winds can reach a maximum wind speed of 25.0 m / s, and the maximum depth of frozen soil exceeds 150 cm.

[0004] The surrounding vegetation of the pumped-storage power station reservoir in this region is poor, rainfall is scarce, and the catchment ditches are dry year-round with virtually no runoff into the reservoir. The construction and operation of the power station require water diversion from outside the watershed. Given the high average evaporation rate in this region and the difficulty and cost of water diversion, effectively suppressing ineffective evaporation from the reservoir is a pressing problem with significant economic benefits. Therefore, we propose an ecological suppression device for ineffective evaporation in pumped-storage power station reservoirs. Utility Model Content

[0005] The purpose of this invention is to provide an ecological suppression device for ineffective evaporation in pumped storage power stations. This invention can effectively suppress ineffective evaporation on the reservoir surface, and at the same time, it can utilize the reservoir surface area and sunlight resources to generate electricity, thereby improving energy utilization efficiency.

[0006] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: an ecological suppression device for ineffective evaporation in pumped storage power station reservoirs, comprising:

[0007] The floating unit is provided in multiple ways. The multiple floating units are connected to each other, float and cover the water surface of the reservoir. The floating unit can adopt a pontoon type or floating tube type support structure.

[0008] Photovoltaic panels are installed above each of the floating units. The photovoltaic panels form a shading plate that covers the surface of the reservoir water, blocking direct sunlight from hitting the water surface and reducing evaporation of the reservoir water surface.

[0009] A buoy floats on the surface of the reservoir and is placed in the gap between multiple floating units. The buoy blocks sunlight from entering the gaps in the photovoltaic panels, further improving the evaporation suppression rate of the system.

[0010] A steam turbine generator is mounted on the surface of a floating unit. The bottom of the floating unit has a sealed air inlet and outlet chambers, which are inverted on the water surface. The air inlet chamber has an air inlet penetrating the upper surface of the floating unit at its top, and the outlet chamber has an air outlet penetrating the upper surface of the floating unit at its top. Both the air inlet and outlet are equipped with one-way valves, allowing air to enter the air inlet chamber through the inlet and exit the air inlet chamber through the outlet. The tops of the air inlet and outlet chambers are connected by a pipe, on which the steam turbine generator is mounted. When the floating unit is affected by waves and sways up and down, the water surface in the air intake chamber will rise and fall relative to the air intake chamber. When the water surface in the air intake chamber drops relative to the air intake chamber, the air intake chamber draws in air through the air inlet. Since the air inlet is equipped with a one-way valve, when the water surface in the air intake chamber rises relative to the air intake chamber, it compresses the air in the air intake chamber and flows into the air outlet chamber through the pipe, and is discharged through the air outlet chamber. When the gas passes through the pipe, it drives the steam turbine generator to generate electricity. It can not only use waves to generate electricity and realize energy utilization, but also reduce the amplitude of wave fluctuations by using the potential energy of waves, thereby reducing the impact of waves on the floating unit.

[0011] The aforementioned ecological suppression device for ineffective evaporation in reservoirs of pumped storage power stations includes a floating unit with connecting ropes on its four sides. Adjacent floating units are connected by connecting ropes, and the floating units near the reservoir bank are fixedly connected to the reservoir dam by connecting ropes. This can greatly reduce the occurrence of large positional displacement of the floating units due to wave influence and prevent microcracks in the photovoltaic panels and floating units.

[0012] The aforementioned ecological suppression device for ineffective evaporation in pumped storage power station reservoirs includes rope reeling and releasing devices on the four side walls of the floating unit. These devices can employ a winch structure to adjust the length of the connecting rope. The two ends of the connecting rope are respectively connected to the rope reeling and releasing devices of two adjacent floating units. Each rope reeling and releasing device is equipped with a control sensor. The device is used to adjust the connecting rope length and can be automatically controlled. The control sensor can be a Hall effect speed sensor to monitor the rotation speed of the winch structure of the rope reeling and releasing device, thereby controlling the length of the connecting rope.

[0013] The aforementioned ecological suppression device for ineffective evaporation in reservoirs of pumped storage power stations includes walkway floats on the connecting rope. Multiple walkway floats are connected in series to form a maintenance channel, facilitating worker movement and maintenance.

[0014] The aforementioned ecological suppression device for ineffective evaporation in reservoirs of pumped storage power stations has four adjustable supports fixedly installed on the upper side of the floating unit. The four adjustable supports are respectively supported at the four corners of the bottom of the photovoltaic panel. By adjusting the support height of the adjustable supports, the height, tilt angle and orientation of the photovoltaic panel can be adjusted.

[0015] The aforementioned ecological suppression device for ineffective evaporation in reservoirs of pumped storage power stations includes an adjustable support base. The base is fixed to the upper surface of a floating unit, and a lifting rod is fixedly installed on the base. The lifting rod can be a hydraulic rod connected to an automatic control system. A universal joint is provided at the top of the lifting rod, and the top of the lifting rod is connected to a photovoltaic panel through the universal joint. The lifting rod can control the support height, and the photovoltaic panel is connected by a universal joint so that the overall tilt angle of the photovoltaic panel can be changed when the lifting rod is adjusted.

[0016] The aforementioned ecological suppression device for ineffective evaporation in reservoirs of pumped storage power stations uses rubber buoys. Rubber material is structurally stable, inexpensive, and has minimal environmental impact. Furthermore, multiple buoys are interconnected by connecting lines, facilitating buoy retrieval and preventing buoys from wandering off or being lost, thus avoiding environmental impact.

[0017] The aforementioned ecological suppression device for ineffective evaporation in reservoirs of pumped storage power stations features a white float that reflects sunlight, resulting in better evaporation prevention. The float diameter is 35mm-80mm; for the same area of ​​water, an 80mm float is more economical and offers the best cost-effectiveness.

[0018] Compared with existing technologies, this utility model uses solar photovoltaic panels laid on the reservoir surface to prevent direct sunlight from hitting the water, reducing water evaporation and lowering the overall water surface evaporation. Rubber balls are used to float on the water along the perimeter of the reservoir and in some areas where there are gaps in the photovoltaic panels, further blocking direct sunlight and reducing water evaporation. This not only overcomes the shortcomings of previous methods but also generates significant economic and social benefits. Furthermore, this utility model improves the energy dissipation capacity of the floating unit during wave resistance, meaning that the floating unit's buoyancy is less susceptible to large positional shifts due to waves, effectively preventing microcracks in the photovoltaic panels and floating unit during this process.
