Obviously, the described embodiments are 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.

[0035] The present invention will be further described below in conjunction with the embodiments.

[0036] Example 1: In a river with a high water flow rate, please refer to Figure 1-Figure 4 ,

[0037] A river channel intelligent retractable water surface algae intercepting net, comprising:

[0038] A self-floating algae-blocking net 6 for intercepting algae, wherein both ends of the self-floating algae-blocking net 6 are connected with a traction component for traction of one end of the self-floating algae-blocking net 6 and an induction-type winding component for movement of the other end of the self-floating algae-blocking net 6;

[0039] A control terminal 1 for controlling the inductive winding assembly, wherein the control terminal 1 is electrically connected to a local control command control terminal 19, the inductive winding assembly is electrically connected to an audible and visual alarm 21 for on-site audible and visual alarms, and the control terminal 1 is wirelessly connected to a cloud service platform 20;

[0040] A chlorophyll sensor 15 for monitoring the algae concentration in the water body of the river, the chlorophyll sensor 15 is installed in the river, and the chlorophyll sensor 15 is wirelessly connected to the cloud service platform 20;

[0041] A flow velocity sensor 16 for the flow velocity of water in the river, the flow velocity sensor 16 is installed in the river, and the flow velocity sensor 16 is wirelessly connected to the cloud service platform 20;

[0042] A video monitoring sensor 18 for real-time monitoring of the state of the self-floating algae blocking net 6, the video monitoring sensor 18 is fixedly installed on one side of the inductive winding assembly, and the video monitoring sensor 18 is wirelessly connected to the control terminal 1;

[0043] A meteorological data receiving terminal 24 for receiving meteorological data, the meteorological data receiving terminal 24 is wirelessly connected to the cloud service platform 20;

[0044] A ship navigation data receiving terminal 25 for receiving ship navigation data, the ship navigation data receiving terminal 25 is wirelessly connected to the cloud service platform 20;

[0045] The computing center 23 used for computing is wirelessly connected to the cloud service platform 20. The computing center 23 processes the data received by the chlorophyll sensor 15, the flow rate sensor 16, the meteorological data receiving terminal 24 and the ship navigation data receiving terminal 25, and transmits the processing results to the control terminal 1 through the cloud service platform 20 for display. If the algae intercepting net needs to be responded to and controlled, instructions can be sent to the control terminal 1 through the wireless network.

[0046] The chlorophyll sensor 15 monitors the algae concentration in the water body of the river in real time. The computing center 23 calculates the algae concentration of the chlorophyll sensor 15. When the algae concentration in the water body is greater than or equal to the set high threshold, the cloud service platform 20 sends a text message reminder to the staff and checks the state of the self-floating algae blocking net 6. If it is in the interception state, it remains unchanged. If it is in the open state, the interception program is executed, and the winding component pulls the self-floating algae blocking net 6 to the interception state. When the algae concentration in the water body is lower than or equal to the set low threshold, the state of the self-floating algae blocking net 6 is checked through the control terminal 1. If it is in the open state, it remains unchanged. If it is in the interception state, the opening program is executed, and the winding component puts the self-floating algae blocking net 6 to the open state. When the algae concentration in the water body is between the high threshold and the low threshold, the control terminal 1 does not change the state and maintains the current state. Only when it drops from the high threshold to below the high threshold for the first time within 72 consecutive hours, the cloud service platform 20 sends a text message reminder to the staff.

[0047] The flow rate sensor 16 monitors the flow rate of the water body in the river channel in real time. The computing center 23 calculates the flow rate. When the water flow rate is greater than or equal to the set high threshold, the cloud service platform 20 sends a text message reminder to the staff and checks the status of the self-floating algae blocking net 6; if it is in an open state, it remains unchanged; if it is in an intercepted state, the opening procedure is executed, and the winding component puts the self-floating algae blocking net 6 to an open state; when the water flow rate drops from above the high threshold to below the low threshold for the first time in 72 consecutive hours, the cloud service platform 20 sends a text message reminder to the staff, maintains the current state of the self-floating algae blocking net 6, and waits for manual processing to respond to sudden floods and protect the self-floating algae blocking net 6.

[0048] The video surveillance sensor 18 monitors the status of the self-floating algae barrier net 6 in real time, and transmits the implementation image back to the cloud service platform 20. The operation center 23 performs software comparison and judgment by real-time shooting of the status characteristics of the self-floating algae barrier net 6 and the alarm graphic characteristics of the graphic library. When the warning conditions are met, the cloud service platform 20 sends SMS reminders to the staff, waiting for manual processing, responding to unexpected situations such as floods and ship impacts, and protecting the algae barrier net.

[0049] The wireless transceiver 22 receives the ship navigation information in real time. When there is ship navigation information, the ship navigation data receiving terminal 25 collects the ship navigation information and transmits it to the control terminal 1 through the cloud service platform 20. The control terminal 1 reports the over-standard alarm message to the local control command control terminal 19 and checks the state of the self-floating algae blocking net 6. If it is in the open state, it remains unchanged; if it is in the interception state, the ship starts to execute the opening procedure five minutes before the ship reaches the self-floating algae blocking net 6 when it is downstream, or starts to execute the opening procedure ten minutes before the ship reaches the self-floating algae blocking net 6 when it is upstream. The inductive winding component puts the self-floating algae blocking net 6 into the open state, and the sound and light alarm 21 performs a sound and light alarm. The interception state is started five minutes after the ship passes through the self-floating algae blocking net 6, and the inductive winding component pulls the self-floating algae blocking net 6 to the interception state, and the sound and light alarm 21 is turned off.

[0050] The self-floating algae-blocking net 6 forms a net bag facing the water flow direction, and the self-floating algae-blocking net 6 forms an open state facing the water flow direction, which is the same as the moving direction of the ship, which can reduce the open time and avoid too much algae being left unblocked;

[0051] When the ship moves downstream, the net bag formed by the self-floating algae-blocking net 6 faces the direction of the water flow, and the self-floating algae-blocking net 6 forms an open state in the direction of the water flow, which is the same as the moving direction of the ship moving downstream. The opening action of the self-floating algae-blocking net 6 and the ship moving downstream are operated simultaneously, which can reduce the opening time and avoid too much algae being left unblocked;

[0052] When the ship moves upstream, the net bag formed by the self-floating algae-blocking net 6 faces the direction of the water flow, and the self-floating algae-blocking net 6 forms an open state in the direction of the water flow, which is opposite to the moving direction of the ship moving upstream. The ship moving upstream can only navigate after the self-floating algae-blocking net 6 is fully opened;

[0053] In summary, it has higher intelligence and safety, and has a certain degree of autonomous judgment ability. It can make timely judgments and responses to various emergencies without human supervision. At the same time, it has higher ship navigability, and can remotely control the retraction and deployment of the self-floating algae intercepting net 6 to form a gap in the river channel, which is convenient for ships to pass through and is conducive to practical use.

[0054] The self-floating algae-blocking net 6 includes a left-bank traction rope fixing buckle 5, a tensile steel wire rope 7, a right-bank traction rope fixing buckle 8, a buoy 12, a net body 13 and an iron chain 14. The two ends of the tensile steel wire rope 7 are respectively fixedly connected to the left-bank traction rope fixing buckle 5 and the right-bank traction rope fixing buckle 8. An iron chain 14 for counterweight is fixedly connected to the bottom of the net body 13. The buoy 12 is evenly spacedly connected to the tensile steel wire rope 7. The left-bank traction rope fixing buckle 5 is connected to an inductive winding assembly, and the right-bank traction rope fixing buckle 8 is connected to a traction assembly.

[0055] The floating body 12 is made of polystyrene foam.

[0056] The floating body 12 is filled in a barrier layer made of PVC waterproof cloth, and both ends are sealed and fixed with spinning threads.

[0057] The traction assembly includes a right bank traction steel wire rope 9 and a right bank fixed anchor rod 11. The right bank fixed anchor rod 11 is fixedly installed on the right bank of the river bank. The right bank fixed anchor rod 11 is fixedly connected to the right bank traction steel wire rope 9, and the right bank traction steel wire rope 9 is fixedly connected to the right bank traction rope fixed buckle 8.

[0058] The inductive winding assembly includes a left bank winch 2, a left bank guide wheel 3, a left bank traction wire rope 4, a left bank pier 10 and a tension sensor 17. The left bank pier 10 is fixedly installed on the left bank of the river bank. The left bank winch 2 and the left bank guide wheel 3 are fixedly installed on the left bank pier 10, and the left bank winch 2 is farther away from the self-floating algae blocking net 6 than the left bank guide wheel 3. The left bank winch 2 is wrapped with the left bank traction wire rope 4, and the left bank traction wire rope 4 is movably connected to the left bank guide wheel 3. The end of the left bank traction wire rope 4 away from the left bank winch 2 is fixedly connected to the sensing end of the tension sensor 17, and the tension sensor 17 is fixedly connected to the left bank traction rope fixed buckle 5.

[0059] The tension sensor 17 monitors the tension on the left bank traction wire rope 4 in real time. When the tension on the left bank traction wire rope 4 is greater than or equal to the set high threshold, the cloud service platform 20 sends a text message reminder to the staff and checks the status of the self-floating algae blocking net 6. If it is in an open state, it remains unchanged. If it is in an intercepted state, the opening procedure is executed. When the tension value drops from above the high threshold to below the low threshold for the first time in 72 consecutive hours, the cloud service platform 20 sends a text message reminder to the staff, maintains the current state of the self-floating algae blocking net 6, and waits for manual processing; respond to any situation that causes the self-floating algae blocking net 6 to pull the left bank traction wire rope 4 with excessive tension, such as floods, ship collisions and other accidents, to protect the self-floating algae blocking net 6.

[0060] The opening procedure of the self-floating algae blocking net 6 is suitable for when the intercepted river channel needs to be opened. The control terminal 1 first sends a command to the sound and light alarm 21 for a five-minute countdown alarm. After the countdown is over, a command is sent to the left bank winch 2 to release the left bank traction wire rope 4. The left bank traction wire rope 4 moves along the left bank guide wheel 3 to increase the length of the left bank traction wire rope 4. With the right bank fixed anchor rod 11 as the fixed point, the self-floating algae blocking net 6 is impacted by the water flow. The left bank traction wire rope 4 is pulled out through the left bank traction rope fixed buckle 5, and the self-floating algae blocking net 6 gradually begins to be released from the left bank. When the left bank winch 2 releases the left bank traction wire rope 4 of a specified length (set in combination with the river channel width), the control terminal 1 sends a command to the left bank winch 2 to stop working. Five minutes later, a command is sent to the sound and light alarm 21 to stop the alarm, and the self-floating algae blocking net 6 begins to open.

[0061] The self-floating algae intercepting net 6 interception program, the control terminal 1 first sends a command to the sound and light alarm 21 to start a five-minute countdown alarm. After the countdown ends, a command is sent to the left bank winch 2 to wind the left bank traction wire rope 4, so that the length of the left bank traction wire rope 4 is reduced. With the right bank fixed anchor rod 11 as the fixed point, under the pulling force of the left bank winch 2, the left bank traction wire rope 4 moves the self-floating algae intercepting net 6 to the left bank through the left bank traction rope fixed buckle 5. When the left bank winch 2 winds the specified length and sets the left bank traction wire rope 4 in combination with the river width, the control terminal 1 sends a command to the left bank winch 2 to stop working. After five minutes, a command is sent to the sound and light alarm 21 to stop the alarm, and the self-floating algae intercepting net 6 starts to intercept;

[0062] When the left bank traction wire rope 4 is tightened or released, the tensile wire rope 7 provides overall buoyancy for the self-floating algae blocking net 6, and the movement resistance in the water is reduced, which is beneficial to the overall movement of the self-floating algae blocking net 6. In addition, during interception, the tensile wire rope 7 provides buoyancy, which is beneficial for the net body 13 to be in a set water level state, and is beneficial for the iron chain 14 to intercept as a whole. The iron chain 14 helps to drive the net body 13 to a vertical state, which is beneficial for the net body 13 to intercept.

[0063] The meteorological data receiving terminal 24 receives temperature and humidity, wind speed and direction, rainfall and radiation data from the meteorological bureau;

[0064] Example 2: Based on Example 1, in a river where the water flow velocity is low or zero, refer to Figure 3 , 4 , 5,

[0065] The right bank of the river channel is fixedly connected with a right bank buttress 27 at the downstream of the right bank fixed anchor rod 11, and the right bank buttress 27 is fixedly connected with a right bank winch 28 and a right bank guide wheel 29. The right bank guide wheel 29 is closer to the left bank than the right bank winch 28. The right bank winch 28 reel is fixedly connected with a right bank traction wire rope 26. The right bank traction wire rope 26 is fixedly connected to the left bank traction rope fixed buckle 5 along the right bank guide wheel 29;

[0066] In a river channel with a low water flow velocity or zero water flow velocity, the water flow power is not enough to flush the self-floating algae blocking net 6 to an open state when executing the opening procedure. Therefore, it is necessary for the left bank winch 2 to unwind while the right bank winch 28 reels the right bank traction wire rope 26 along the right bank guide wheel 29. The right bank traction wire rope 26 drives the left bank traction rope fixed buckle 5 to move, and the left bank traction rope fixed buckle 5 drives the end of the self-floating algae blocking net 6 close to the left bank winch 2 to approach the right bank winch 28, and the self-floating algae blocking net 6 is brought close to the right bank edge. Finally, the river channel with a low water flow velocity or zero water flow velocity is opened to an open state, thereby improving adaptability.

[0067] Embodiment 3, based on embodiment 2:

[0068] The computing center 23 uses the flood prediction GAST model combined with the rainfall data predicted by the Meteorological Bureau to issue early warnings for potential floods. The control terminal 1 controls the network body 13 to execute to an open state before the flood reaches the network body 13 according to the warning information.

[0069] The computing center 23 simulates the chlorophyll content in the next 3 days and 7 days through the algae bloom growth logistic model, combined with the real-time chlorophyll monitoring data of the chlorophyll sensor 15, the future radiation data and temperature and humidity data of the weather forecast of the Meteorological Bureau, and outputs the predicted value of chlorophyll to give early warning of potential algae blooms that may occur. The control terminal 1 controls the network body 13 to control the open state or closed state according to the warning information.

[0070] Early warnings and advance plans can be made based on the predicted weather conditions and algae conditions, which is conducive to accurate control and dynamic management of the interception network, which is efficient, saves time and effort.

[0071] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
