[0002] In recent years, my country has repeatedly experienced flood disasters beyond normal range, especially the sudden and continuous large-scale rainfall that caused the water level of inland rivers, lakes, reservoirs and other water bodies to rise abnormally, exceeding the limit of their water holding capacity. Once the flood overflows the river or dam and floods onto the land, it will impact or damage infrastructure such as buildings, roads, bridges, etc., leading to traffic interruptions, power supply and water supply system paralysis, and people's daily life and industrial production are in trouble. What's more serious is that flood disasters will directly threaten people's lives and safety. In addition, floods will also cause economic losses such as reduced crop yields and factory shutdowns.

[0003] Water level monitoring is a core component of the flood warning system. Through real-time and accurate unmanned monitoring of water level changes in inland rivers, lakes, reservoirs and other water bodies, the possibility and severity of floods can be predicted in a timely manner, and people in relevant areas can be reminded to evacuate and prepare in advance.

[0004] When a flood occurs, a stable power supply for the field water level monitoring system is particularly important.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] An embodiment of a flood water level early warning system powered by an integrated photovoltaic storage aluminum-air battery of the present invention is as follows: Figures 1 to 3 shown.

[0024] A flood water level early warning system powered by an integrated photovoltaic storage aluminum-air battery is installed on the land side of a river bank dam and is used to detect the water level data of inland rivers, lakes, reservoirs and other water bodies throughout the day, including a collection module, a photovoltaic power generation module 105, an energy storage module, an emergency module and a control module 107. The collection module can be started to collect and upload water level data, and the photovoltaic power generation module 105, the energy storage module and the emergency module can all be started to power the collection module. The control module 107 can control the collection module, the photovoltaic power generation module 105, the energy storage module and the emergency module to start or shut down, and can store the excess electric energy in the photovoltaic power generation module 105 in the energy storage module.

[0025] The flood water level warning system powered by an integrated photovoltaic storage aluminum-air battery has mode 1, mode 2 and mode 3. When the water level is less than the first preset value and the weather is clear, the first preset value is the maximum value of the water level within the normal range, in mode 1, the photovoltaic power generation module 105 is started, and the excess electric energy is stored in the energy storage module, and the energy storage module and the emergency module are turned off; when the water level is less than the first preset value and the weather is gloomy, it is in mode 2, the energy storage module is started, and the photovoltaic power generation module 105 and the emergency module are turned off; when the water level is greater than the first preset value and the weather is gloomy, it is in mode 3, the emergency module is started, and the photovoltaic power generation module 105 and the energy storage module are turned off.

[0026] Specifically, a flood water level warning system powered by an integrated photovoltaic and aluminum-air battery also includes a pipeline floating barrel 101.

[0027] The pipeline float barrel 101 can ensure that the transmission pipeline remains floating on the water surface. During the flood season, floods may cause the water level to rise rapidly, and the pipeline float barrel 101 can prevent the pipeline from being submerged or damaged.

[0028] This embodiment is provided with a collection module, a photovoltaic power generation module 105, an energy storage module, an emergency module and a control module 107. When in use, the control module 107 is used to start the collection module, and the collection module is used to collect and upload water level data.

[0029] When the water level is less than the first preset value and the weather is clear (the first preset value is the maximum value of the water level within the normal range. When the water level is less than the first preset value, it means that there is no flood and the water level is normal, which is in the non-flood season. When the water level is greater than the first preset value, it means that there is a flood and the water level is abnormal, which is in the flood season). The flood water level warning system powered by the integrated photovoltaic storage aluminum-air battery is in mode one. The control module 107 controls the photovoltaic power generation module 105 to start and power the collection module. The photovoltaic power generation module 105 generates electricity so that the collection module can normally collect water level data, which is convenient for monitoring the water level. If the photovoltaic power generation module 105 generates excess electricity, the control module 107 is used to power the energy storage module and store the excess electricity in the energy storage module.

[0030] When the water level is less than the first preset value and the weather is gloomy, the flood water level warning system powered by an integrated photovoltaic aluminum-air battery is in mode two. The control module 107 controls the energy storage module to start powering the collection module. The energy storage module generates electricity so that the collection module can normally collect and upload water level data, ensuring that the flood water level warning system powered by an integrated photovoltaic aluminum-air battery works normally during the non-flood season and on cloudy days.

[0031] When the water level is greater than the first preset value and the weather is gloomy, the flood water level warning system powered by the integrated photovoltaic aluminum-air battery is in mode three. The control module 107 controls the emergency module to start powering the collection module. The emergency module generates electrical energy so that the collection module can normally collect and upload water level data, ensuring that the water level warning system can work normally when a flood occurs.

[0032] That is, in this embodiment, the photovoltaic power generation module 105 is used to generate electricity to power the collection module in the non-flood season and when the weather is clear, and the excess electricity is stored in the energy storage module. In the non-flood season and when the weather is gloomy, the electricity stored in the energy storage module is used to power the collection module.

[0033] Once the flood season occurs, which is often accompanied by strong winds and heavy rains, the photovoltaic power generation module 105 will not be able to generate electricity normally because it cannot receive sunlight for a long time. At this time, the energy storage module will be used to generate electricity, and before the energy storage module is exhausted, the control module 107 will be used to cooperate with the energy storage module to start the emergency module. When floods arrive during the flood season, the emergency module generates electricity so that the collection module can normally collect and upload water level data without manual supervision, thus achieving continuous power supply throughout the day and reducing the difficulty of flood level monitoring.

[0034] In this embodiment, the acquisition module includes a water level monitoring sensor 102 and a 5G wireless receiving module 104. The water level monitoring sensor 102 is used to measure the water level height in real time and form water level warning data. The 5G wireless receiving module 104 can send the water level warning data to the remote monitoring platform of the peripheral device.

[0035] In this embodiment, the control module 107 is provided with an electric energy converter, which can store the excess electric energy in the photovoltaic power generation module 105 in the energy storage module.

[0036] By providing an electric energy converter, if the photovoltaic power generation module 105 generates excess electric energy, the electric energy converter in the control module 107 supplies power to the energy storage module.

[0037] As the core component of the flood water level warning system powered by an integrated photovoltaic storage aluminum-air battery, the control module 107 adjusts the working status of the photovoltaic power generation module 105, the energy storage module or the emergency module according to the power supply status, water level status and instructions of the external remote monitoring platform of the real-time photovoltaic power generation module 105, the energy storage module or the emergency module, ensures the normal operation of the water level monitoring sensor 102 and the 5G wireless receiving module 104, and realizes the normal collection and upload of data.

[0038] In this embodiment, the energy storage module includes a lithium energy storage battery 106. When in use, the excess electric energy in the photovoltaic power generation module 105 will be stored in the lithium energy storage battery 106.

[0039] In this embodiment, the emergency module includes an aluminum-air battery 103, and the aluminum-air battery 103 includes a siphon chamber 203, a horizontal side water storage tank 208, and a battery cell. A siphon tube 201 is provided in the siphon chamber 203, one end of the siphon tube 201 extends into the siphon chamber 203, and the other end extends into the water, and the height of the highest point of the siphon tube 201 from the water surface of the river, lake, or reservoir is less than the height of the water column supported by the atmospheric pressure. When the flood water level warning system powered by the integrated photovoltaic storage aluminum-air battery is in mode 1 and mode 2, there is no water inside the siphon tube 201, and when the flood water level warning system powered by the integrated photovoltaic storage aluminum-air battery is in mode 3, the siphon tube 201 is filled with water.

[0040] The siphon chamber 203 is connected to the horizontal side water tank 208, the battery cell is arranged in the horizontal side water tank 208 and is connected to the horizontal side water tank 208 through the downpipe 204, and an aluminum plate 205, solid KOH and a catalyst are arranged inside the battery cell. The solid KOH and the catalyst 207 can be converted into an electrolyte after reacting with water, and generate electrical energy after fully contacting with the aluminum plate 205.

[0041] Furthermore, a plurality of battery cells are arranged in parallel in the horizontal side water storage tank 208, and one of the battery cells is connected to the horizontal side water storage tank 208 through the downpipe 204. Specifically, the first battery cell among the plurality of battery cells arranged in parallel can be connected to the horizontal side water storage tank 208 through the downpipe 204. Two adjacent battery cells are connected through a connecting pipe. An aluminum plate 205, solid KOH and a catalyst are arranged inside each battery cell.

[0042] Specifically, the aluminum-air battery 103 is configured as a box structure, which is less affected by external weather and can meet the needs of long-term storage and emergency power supply in flood disasters.

[0043] In this embodiment, the aluminum-air battery 103 is provided. When there is no flood, there is no water inside the siphon tube 201. When there is a flood, the siphon tube 201 is filled with water, so that when the river water level is higher than the water level in the siphon chamber 203, the water will flow back into the siphon chamber 203 through the siphon tube 201. After the water fills the siphon chamber 203, it overflows into the horizontal side water storage tank 208, flows along the downpipe 204 into the first battery cell close to the siphon chamber 203, and then flows into the remaining battery cells in sequence through the connecting pipes between the battery cells, that is, the water is diverted to the inside of each battery cell.

[0044] After the water is mixed with the solid KOH and catalyst 207 inside the battery cell, the electrolyte of the aluminum-air battery 103 is formed. When the electrolyte fills the battery cell, it contacts the aluminum plate 205, and a chemical reaction occurs, converting the chemical energy into the required electrical energy. After the aluminum-air battery 103 starts to generate electricity, it supplies power to the water level monitoring sensor 102, the 5G wireless receiving module 104 and the control module 107, and uses the control module 107 to store the excess power in the lithium energy storage battery 106. After the water level monitoring sensor 102 collects the flood water level in real time, it uploads data, warns and receives instructions from the remote monitoring platform of the external device through the 5G wireless receiving module 104. By connecting the battery cells of the aluminum-air battery 103 in series, the water level monitoring sensor 102 and the 5G wireless receiving module 104 are directly powered, ensuring that the flood water level warning system powered by the integrated light storage aluminum-air battery can work normally when a flood occurs, and the water level data is sent to the external remote monitoring platform in real time, realizing water level monitoring in an unmanned state.

[0045] Furthermore, the aluminum-air battery 103 also includes a water pump 206. When the flood level warning system powered by the integrated photovoltaic and aluminum-air battery is in mode three, the energy storage module can drive the water pump 206 to start. The water pump 206 can pump water into the siphon 201 and fill the siphon 201 with water.

[0046] When there is no flood, the water level is normal (less than the first preset value), the water pump 206 does not work, and there is no water in the siphon tube 201, so the siphon effect will not occur, and water will not flow back into the siphon chamber 203. When a flood occurs, the water level is abnormal (greater than the first preset value), the lithium energy storage battery 106 is too low, and an alarm is sent to the remote monitoring platform of the peripheral device through the control module 107, so that the lithium energy storage battery 106 supplies power to the water pump 206, and water is pumped into the siphon tube 201, so that the siphon tube 201 is filled with water. When the water level of rivers, lakes and reservoirs is too high, there is a height difference between the water level of the water to be detected and the water level in the siphon chamber 203. Once the conditions for the siphon effect are met, a siphon phenomenon will occur, and water will flow into the siphon chamber 203 through the siphon tube 201.

[0047] Furthermore, a river water purification device 202 is provided at the siphon 201 to filter the water, and a reverse osmosis filter device can be used.

[0048] By setting up the river water purification device 202, when water is poured into the siphon chamber 203 through the siphon tube 201, the water will first be filtered by the river water purification device 202, so that the filtered water meets the water quality requirements of the electrolyte of the aluminum-air battery 103, ensuring the cleanliness of the electrolyte of the aluminum-air battery 103, so that the solid KOH and the catalyst can be converted into the electrolyte after contacting the filtered water, and generate electricity after fully contacting the aluminum plate 205. The river water purification device 202 is a prior art and will not be described in detail here.

[0049] In this embodiment, a float 209 and a drain valve 210 are provided in the horizontal side water storage tank 208. The drain valve 210 has a water inlet and a water outlet. The water inlet is connected to the horizontal side water storage tank 208, and the water outlet extends out of the horizontal side water storage tank 208. In the initial state, the water inlet and the water outlet are separated by a synchronous plug to prevent water from flowing out. The synchronous plug is connected to the float 209, and the float 209 can drive the synchronous plug to move synchronously. When the water level in the horizontal side water storage tank 208 is greater than the second preset value, the synchronous plug can leave the water outlet, connect the water inlet and the water outlet, and open the drain valve 210. The second preset value is the maximum value of the water level height in the horizontal side water storage tank 208.

[0050] By arranging a floating block 209 and a drain valve 210 in the horizontal side water storage tank 208, once the water level in the horizontal side water storage tank 208 is too high, the floating block 209 will float up and drive the synchronous plug to move upward, and when the water level in the horizontal side water storage tank 208 is greater than the second preset value, the drain valve 210 will be opened to drain the excess water. After drainage, the floating block 209 will descend to drive the synchronous plug to move downward, so that the drain valve 210 is closed.

[0051] Alternatively, the drain valve 210 is an electrically controlled valve, a water level sensor is provided on the float 209, the water level sensor is connected to the control module 107, and when the water level in the horizontal side water storage tank 208 is greater than a second preset value, the water level sensor can feed back the detected water level data to the control module 107, and drive the drain valve 210 to open through the control module 107.

[0052] In combination with the above embodiments, the specific working process is as follows:

[0053] When in use, when the water level is less than the first preset value and the weather is clear, no flood has occurred at this time, and it is in the non-flood season. The flood water level warning system powered by the integrated photovoltaic storage aluminum air battery is in mode 1, and the photovoltaic power generation module 105 is controlled by the control module 107 to start to power the water level monitoring sensor 102 and the 5G wireless receiving module 104. The photovoltaic power generation module 105 generates electricity so that the water level monitoring sensor 102 can normally collect water level data, and sends the water level warning data to the external remote monitoring platform through the 5G wireless receiving module 104, which is convenient for monitoring the water level. If the photovoltaic power generation module 105 generates excess electricity, the power converter in the control module 107 is used to power the lithium energy storage battery 106.

[0054] When the water level is less than the first preset value and the weather is cloudy, no flood occurs and it is in the non-flood season. The flood water level warning system powered by the integrated photovoltaic aluminum-air battery is in mode 2. The control module 107 controls the lithium energy storage battery 106 to start powering the water level monitoring sensor 102 and the 5G wireless receiving module 104, so that the water level monitoring sensor 102 can collect water level data normally, ensuring that the flood water level warning system powered by the integrated photovoltaic aluminum-air battery works normally in the non-flood season and on cloudy days.

[0055] Once the flood season occurs, which is often accompanied by strong winds and heavy rain, the photovoltaic power generation module 105 will not be able to generate electricity normally because it cannot receive sunlight for a long time. At this time, the lithium energy storage battery 106 will be used to generate electricity, and by setting an emergency module, when there is no flood, the water level is low (less than the first preset value), the water pump 206 does not work, and there is no water in the siphon 201, so the siphon effect will not occur, and water will not flow back into the siphon chamber 203. When a flood occurs, the lithium energy storage battery 106 is too low in power and an alarm is sent to the remote monitoring platform of the external device through the control module 107, so that the lithium energy storage battery 106 supplies power to the water pump 206, pumps water into the siphon 201, and fills the siphon 201 with water. When the water level of rivers, lakes and reservoirs is too high, there is a height difference between the water level of the water to be detected and the water level in the siphon chamber 203. Once the conditions for the siphon effect are met, a siphon phenomenon will occur, and water will flow into the siphon chamber 203 through the siphon 201.

[0056] After the water fills the siphon chamber 203, it overflows into the horizontal side water storage tank 208, flows along the downcomer 204 into the first battery cell near the siphon chamber 203, and then flows into the remaining battery cells in turn through the connecting pipes between the battery cells, that is, the water is diverted to the interior of each battery cell.

[0057] After the water is mixed with the solid KOH and catalyst 207 inside the battery cell, the electrolyte of the aluminum-air battery 103 is formed. After the electrolyte fills the battery cell, it contacts the aluminum plate 205, and a chemical reaction occurs, converting the chemical energy into the required electrical energy. In the process of water pouring into the siphon chamber 203 through the siphon tube 201, the water will first be filtered by the river water purification device 202, so that the filtered water meets the water quality requirements of the electrolyte of the aluminum-air battery 103, ensuring the cleanliness of the electrolyte of the aluminum-air battery 103.

[0058] After the aluminum-air battery 103 starts to generate electricity, it can supply power to the water level monitoring sensor 102, the 5G wireless receiving module 104 and the control module 107, and use the power converter to store the excess power in the lithium energy storage battery 106. After the water level monitoring sensor 102 measures the water level height and forms water level warning data, it is sent to the remote monitoring platform of the peripheral device through the 5G wireless receiving module 104 to warn and receive instructions from the remote monitoring platform.

[0059] Once the water level in the horizontal side water storage tank 208 is too high, the float block 209 will float up and drive the synchronous plug to move upward, and when the water level in the horizontal side water storage tank 208 is greater than the second preset value, the drain valve 210 will open to discharge the excess water.

[0060] A field distributed microgrid system is constructed using photovoltaic power generation module 105, lithium energy storage battery 106 and aluminum-air battery 103. Under normal circumstances, the microgrid system uses photovoltaic power generation module 105 and lithium energy storage battery 106 to jointly supply power to water level monitoring sensor 102. After measuring the water level height and forming water level warning data, the water level warning data is uploaded to the remote monitoring platform of the peripheral device through 5G wireless receiving module 104. When a flood natural disaster occurs, the siphon principle is used to pour river water into aluminum-air battery 103. After the photovoltaic power generation module 105 and lithium energy storage battery 106 run out of power, they can still supply power to water level monitoring sensor 102 and 5G wireless receiving module 104 to ensure the normal upload of water level data during the flood.

[0061] By introducing the aluminum-air battery 103, its long-term storage and high energy density characteristics are brought into play, and it can provide stable power output in special unmanned environments such as flood season and outdoors.
