[0002] At present, the electricity supply in the whole society is becoming increasingly tight. With the introduction of the concept of "carbon peak and carbon neutrality", pumped-storage power stations are increasingly valued due to their rapid start and stop, strong load tracking capability, and rapid response to sudden changes in system load. They can be used to smooth out the instability and randomness of new energy power generation and reduce adverse effects on the power grid.

[0003] With the rapid development of pumped storage technology, my country has also planned and built a number of pumped storage power stations in severe cold regions such as the northwest and northeast. Affected by the cold climate, the pumped storage power stations in this region face severe freezing challenges in winter. When the reservoir freezes, it not only occupies the effective storage capacity and affects the power generation capacity, but also has an important impact on the safety of hydraulic structures and even the operation of hydro-generator units. Studying the evolution of ice conditions in water storage power stations in cold regions and determining reasonable and effective anti-icing methods are of great significance to ensure the safe and stable operation of pumped storage power stations in winter.

The present invention provides the following embodiments.

[0031] like Figures 1 to 3 As shown, it is a structural schematic diagram of the pumped storage power station reservoir ice change and anti-icing test experimental device in this embodiment. The experimental device in this embodiment can be used to test the changing laws of different variables such as air temperature, water depth and water temperature, wind speed, light radiation intensity, water flow velocity, etc. on the growth, melting and rupture of the ice cover, as well as to analyze the influence of different nozzle structures and shapes, installation angles and positions, bubble sizes and flow velocities on the anti-icing effect.

[0032] like Figures 1 to 3 As shown, the experimental device in this embodiment includes an experimental test system 2, an anti-icing test system 1001 and a data detection and acquisition system 1002. Among them, the experimental test system 2 includes a simulation box 205, and water can be injected into the simulation box 205 to facilitate experimental operation. In this embodiment, the experimental test system 2 also includes a support table 213, and the simulation box 205 is placed on the support table 213. In this embodiment, the simulation box 205 is placed above the support table 213. In this embodiment, a centrifugal pump 8 is connected to one side of the simulation box 205. The centrifugal pump 8 is used to inject water into the simulation box 205 for practical experiments. In this embodiment, one end of the centrifugal pump 8 is connected to a pipeline, and the end of the pipeline is connected to a pipe joint through a thread, and the pipe joint is connected to the experimental system 2, and the other end is connected to a water source through a pipeline. Therefore, the centrifugal pump 8 in this embodiment can inject water from the water source into the simulation box 205 through a pipeline. In addition, as Figure 2As shown, a high-speed camera 1 is installed on one side of the simulation box 205 in this embodiment. The high-speed camera 1 is used to take real-time and uninterrupted photos of the environment in the simulation box 205, and transmit the photos to the analysis system outside. The operator can grasp the changes in the simulation box 205 in real time through the analysis system. Specifically, the high-speed camera 1 in this embodiment is placed on the outside of the simulation box 205 through a bracket to shoot the growth, melting and rupture changes of the ice sheet. In this embodiment, a long-arc xenon lamp 201 and a lamp stand 202 are also installed on one side of the simulation box 205, wherein the lamp stand 202 is located on one side of the simulation box 205, and a long-arc xenon lamp 201 is installed on the top of the lamp stand 202. The long-arc xenon lamp 201 provides a light source for irradiation. In this embodiment, the lamp stand 202 is fixed to the simulation box 205 by bolts or welding, and the long-arc xenon lamp 201 is fixed to the lamp stand 202 by bolts. As shown in FIG. Figure 2 As shown, a wind speed generating device 206 is installed on the inner wall of the simulation box 205 in this embodiment, and the wind speed generating device 206 is embedded in the upper part of the side wall of the simulation box 205; the wind speed generating device 205 works so that the air flow generates wind speed, which blows toward the liquid surface of the simulation box 205 to simulate the actual situation of the liquid surface in the natural environment. In addition, the simulation box 205 in this embodiment also includes a thermal insulation layer 212, which insulates the simulation box 205 to avoid the situation where the temperature of the simulation box 205 changes too quickly; the thermal insulation layer 212 is wrapped around the simulation box 205 to play a role of insulation and simulate real natural conditions. In addition, Figure 2 As shown, the bottom surface of the simulation box 205 in this embodiment contains a plurality of concentric holes, the side surface of the simulation box 205 contains a plurality of holes, the holes of the simulation box 205 contain threads, and the holes are sealed by water blocking plugs 214 to prevent water in the simulation box 205 from flowing out.

[0033] In addition, if Figure 2 as well as Figure 3As shown, the data detection and acquisition system 1002 in this embodiment includes an ice radar 204, a pressure sensor 210, a displacement sensor 211, a flow rate sensor 208, a temperature sensor 203, a wind speed sensor 207, and a radiation sensor 209, and the above sensors correspond to changes in monitoring related data respectively. Specifically, the ice radar 204 and the wind speed sensor 207 in this embodiment are fixed to the upper inner wall of the simulation box 205 through holes. The ice radar 204 is used to monitor the ice layer conditions of the water in the simulation box 205 when it is frozen, such as the thickness of the ice layer. When the wind speed generating device 206 is working, the wind speed is monitored by the wind speed sensor 207 to obtain wind speed-related data. In addition, the flow velocity sensor 208, the temperature sensor 203, and the radiation sensor 209 in this embodiment are placed in the simulation box 205 through holes, and the number of the sensors gradually decreases from top to bottom in the simulation box 205. In this embodiment, since the number of the flow velocity sensors 208, the temperature sensors 203, and the radiation sensors 209 in the simulation box 205 gradually decreases from top to bottom, the temperature sensor 203 and the radiation sensor 209 can monitor the flow velocity, temperature, light intensity and other data at different water layers in the simulation box 205. In addition, the pressure sensor 210 and the displacement sensor 211 in this embodiment are fixed to the inner side of the simulation box 205 through holes, and the pressure sensor 210 and the displacement sensor 211 are evenly arranged along the length and width directions of the simulation box 205, and two pressure sensors 210 and displacement sensors 211 are evenly arranged from the surface to the bottom of the ice cover in the water depth direction.

[0034] In this embodiment, the ice radar 204 and the wind speed sensor 207 are fixed to the upper part of the inner wall of the simulation box 205 by welding brackets.

[0035] like Figure 1 to Figure 3As shown, the anti-icing test system 1001 in this embodiment includes an air compressor 7, a one-way throttle valve 4, an angle disc 3, and a nozzle 9, wherein the air compressor 7, the one-way throttle valve 4, the angle disc 3, and the nozzle 9 are connected in sequence, the air compressor 7 is connected to the angle disc 3 through a pipeline, and a fluid temperature sensor 5 and a flow sensor 6 are also connected to the pipeline between the air compressor 7 and the angle disc 3. In this embodiment, a one-way throttle valve 4 is also provided on the pipeline between the air compressor 7 and the angle disc 3, and the one-way throttle valve 4 is connected to the pipeline through a thread, and the angle disc 3 is connected to the pipeline. At the end, the other end of the angle disk 3 is connected to the hose; in this embodiment, a plurality of nozzles 9 are arranged in the simulation box 205, the nozzles 9 are connected to the hose, and the end of the hose is matched with the inner thread of the hole of the simulation box 205 through a threaded joint, and auxiliary sealing is performed by a sealing ring and a sealant. Therefore, when the air compressor 7 in this embodiment is working, air can be injected into the simulation box 205 through the pipeline, and the air is dispersedly injected into the water in the simulation box 205 through the angle disk 3 and the cooperation of a plurality of hoses and nozzles 9, thereby realizing the disturbance of the water body and avoiding the occurrence of ice problems.

[0036] It is worth noting that the anti-icing test system 1001 in this embodiment not only prevents ice formation by air disturbance of the water body, but also prevents ice formation in the water body of the water flow disturbance simulation box 205 in this embodiment, as shown in the following example. Figures 1 to 3 As shown, the anti-icing test system 1001 in this embodiment also includes an outer centrifugal pump 8, which is connected to the simulation box 205 through a pipeline, and a fluid temperature sensor 5, a flow sensor 6 and a one-way throttle valve 4 are respectively arranged on the pipeline, and the end of the pipeline is connected to an angle disk 3, and the angle disk 3 is connected to the nozzle 9 in the simulation box 205 through a hose. In this embodiment, the outer centrifugal pump 8 can inject water into the simulation box 205 through the pipeline when it is working. After the water flow is ejected through the nozzle 9, it disturbs the water body in the simulation box 205, thereby preventing the water body from freezing.

[0037] In the above-mentioned anti-icing test system 1001, no matter whether the water body is disturbed by air or by water flow, the fluid temperature sensor 5 and the flow sensor 6 monitor the temperature and flow of the fluid in the pipeline to obtain the data of the fluid temperature and flow, and obtain the influence of the fluid on the freezing by simulating the freezing situation in the box 205.

[0038] In addition, if Figure 1 as well as Figure 3As shown, the outer centrifugal pump 8 and the air compressor 7 in this embodiment can share a pipeline as a power mechanism to be connected to the simulation box 205, and the power mechanism generates fluid disturbance to the water in the simulation box 205. In this embodiment, when the outer centrifugal pump 8 and the air compressor 7 are connected to the simulation box 205 as a common pipeline, the centrifugal pump 8 and the air compressor 7 are connected in parallel at the end of the pipeline. It is worth noting that valves are respectively provided on the pipelines at the working ends of the centrifugal pump 8 and the air compressor 7 to avoid interference between the centrifugal pump 8 or the air compressor 7 during operation.

[0039] The test device in this embodiment is placed in a low-temperature laboratory during the experiment. The laboratory temperature can be adjusted according to the experimental needs. A certain amount of water is injected into the simulation box 205 through the centrifugal pump 8 on one side of the simulation box 205. The high-speed camera 1 is adjusted to a suitable angle and position to take real-time photos of the internal environment of the simulation box 205. The wind speed generating device 206 and the long arc xenon lamp 201 in this embodiment are turned on and off and adjusted to the corresponding gears. The relevant equipment can be adjusted during the experiment according to the actual situation. The ice radar in the data detection and acquisition system 1002 in this embodiment 204, flow rate sensor 208, temperature sensor 203, wind speed sensor 207, radiation sensor 209 work and detect data such as ice thickness, water velocity, air temperature and water temperature, wind speed, light intensity, etc. in simulation box 205 in real time. High-speed camera 1 shoots the formation process of ice cover. The experimental device in this embodiment transmits the above data to the computer in real time according to the experimental settings for data processing and analysis. After data processing and analysis, the results of the influence of wind speed, temperature and flow rate on the icing situation can be obtained, so as to provide theoretical data support for the icing situation of the pumped storage power station reservoir in the later stage.

[0040] In addition, in this embodiment, after the ice cover is formed in the simulation box 205, the water at the bottom of the simulation box 205 can be pumped out by the centrifugal pump 8, or the centrifugal pump 8 can be used to continue to inject water into the simulation box 205 to simulate the effect of water pumping and draining conditions on the rupture of the ice cover. The deformation and crack propagation of the ice cover are recorded in real time by the high-speed camera 1 and transmitted to the computer for video, image processing and data analysis.

[0041] In addition, this embodiment also provides an experimental scheme for anti-icing test, specifically, the anti-icing test is performed by gas or by liquid. The specific scheme is as follows.

[0042] When the anti-icing test is performed by gas, the experiment is conducted under the initial condition of no ice cover or ice cover of a certain thickness. The wind speed generating device 206, the long arc xenon lamp 201 and the air compressor 7 are kept turned on and off under different variables and adjusted to the corresponding gears. The air compressor 7 works to inject gas into the simulation box 205 through the pipeline. The fluid temperature sensor 5 and the flow sensor 6 detect the temperature and flow of the gas. The gas enters the water body in the simulation box 205 from the bottom of the simulation box 205 through the nozzle 9 and disturbs the water body. The number, shape and distance of the nozzle 9 from the bottom of the simulation box 205 can be selected and adjusted according to the experimental needs. The water disturbance range, the movement process and morphological changes of the airflow are recorded by the high-speed camera 1, and the ice radar 204 is used to detect the change of ice thickness, so as to obtain the results of the gas anti-icing test.

[0043] When the anti-icing test is performed by liquid, the centrifugal pump 8 on the outside of the experimental device in this embodiment works, and the centrifugal pump 8 is adjusted to a certain flow rate. The centrifugal pump 8 works to inject liquid into the simulation box 205 through the pipeline. The liquid enters the water body from the bottom of the simulation box 205 through the nozzle 9 and disturbs the water body. The number, shape and distance of the nozzle 9 from the bottom of the simulation box 205 can be selected and adjusted according to experimental needs. The high-speed camera 1 is used to shoot and record the water disturbance range and the movement process and morphological changes of the liquid flow. The ice radar 204 is used to detect the change in ice thickness, so that the result of the liquid anti-icing test can be obtained.

[0044] The experimental device in this embodiment can be used to simulate the icing situation in the experimental simulation box 205, simulate the real environmental conditions through the wind speed generating device 206 and the long arc xenon lamp 201, and monitor the data in real time through the ice radar 204, the flow rate sensor 208, the fluid temperature sensor 5, the wind speed sensor 207 and the radiation sensor 209, and use the high-speed camera 1 to shoot the formation process of the ice cover in the simulation box 205, so as to obtain the influence of environmental factors on icing. In addition, the pumping or injection operation of the centrifugal pump 8 can simulate the influence of the pumping and waterproofing working conditions on the rupture of the ice cover. On the other hand, the experimental device in this embodiment can be used to test the anti-icing through the anti-icing test system 1001. The test is performed by the air compressor 7 to generate airflow to disturb the water in the simulation box 205, and the high-speed camera 1 is used to shoot the disturbance, and the ice thickness change is detected by the ice radar 204 to obtain the gas anti-icing test result. The liquid anti-icing test is performed by the centrifugal pump 8 outside the experimental device to inject liquid into the simulation box 205 to disturb the water, and the high-speed camera 1 is used to shoot the disturbance, and the ice thickness change is detected by the ice radar 204 to obtain the liquid anti-icing test result.
