An independent reservoir water level and arc gate linkage system is established at the power station. When the water level in front of the dam or the rising trend of the water level in front of the dam reaches the alarm threshold, the water level in front of the dam and the flood discharge arc gate are linked, which plays an emergency automatic opening and closing function, ensuring that when the water level in front of the dam is too high, rises too fast, or in an emergency, the flood discharge arc gate can be automatically opened safely, promptly, and effectively to ensure the safe operation of the dam.

A second motor 11 is installed on the outer wall of one of the baffle bars 8, and the second motor 11 is transmission-connected to the threaded rod 10 through a transmission belt. The outer wall of the threaded rod 10 is threadedly connected to a cleaning bar 2 that is slidably connected to the outer wall of the reservoir arc gate 6, and a cleaning unit 9 is installed on the side wall of the cleaning bar 2.

[0029] like Figure 1 , 2As shown in , 3, and 6, the reservoir water level and arc gate linkage system structure in the utility model is similar to the existing reservoir water level and arc gate linkage system structure, such as the intelligent safety early warning system of a dam flood discharge facility disclosed in the patent with publication number CN219872551U. The main improvement of the utility model is that it can realize the linkage between the reservoir water level and the arc gate, and formulate arc gate opening targets and plans according to the water level rise, so as to ensure that the flood discharge arc gate can be automatically opened safely, timely and effectively in an emergency situation when the water level in front of the dam is too high or rises too fast, so as to ensure the safe operation of the dam and clean the water plants on the outer wall of the arc gate; the plurality of reservoir arc gates 6 in the utility model include a first arc gate, a second arc gate, a third arc gate, and a fourth arc gate. The second arc gate, the third arc gate, the fourth arc gate, the fifth arc gate, the sixth arc gate, the seventh arc gate, the eighth arc gate, the ninth arc gate and the tenth arc gate; according to the set water level start-up program, the water level of the upstream reservoir is measured by the water level meter 1, and the water level meter 1 transmits the water level signal to the computer monitoring system 3 in real time by using a cable. The computer monitoring system 3 calculates the number and opening degree of the reservoir arc gates 6 that need to be opened at the current water level. After the calculation is completed, the computer monitoring system 3 transmits the corresponding instructions to the arc gate communication machine 4 first, and after being transferred by the arc gate communication machine 4, it is transmitted to the arc gate control system 5 for command, and then the corresponding reservoir arc gate 6 is opened to the corresponding opening to prevent the arc gate from being flooded over the top;

[0030] The specific control method is as follows: when the upstream water level is lower than the set height, the conditions of the reservoir water level linkage system are not met, the system does not participate in the work, and the reservoir arc gate is started and stopped based on manual judgment.

[0031] When the upstream water level is higher than the set height, the monitoring system activates the reservoir water level linkage arc gate process and sounds the flood control alarm.

[0032] If the upstream water level exceeds the set height and the reservoir water level drops below the set height 20 minutes later, the monitoring system reservoir water level linkage arc gate process will exit.

[0033] When the upstream water level exceeds the set height, and 20 minutes later, the reservoir water level rises above the set height, the monitoring system will sound the flood alarm again, and command the arc gate control system 5 to immediately open the fifth arc gate to 1 meter, and then open the sixth arc gate to 1 meter after an interval of 60 seconds; after the fifth arc gate is opened to 1 meter, open the seventh arc gate to 1 meter; after the sixth arc gate is opened to 1 meter, open the eighth arc gate to 1 meter.

[0034] If the upstream water level exceeds the set height, the flood alarm is sounded for more than 20 minutes from the set height, and the fifth to eighth arc gates have been opened to 1 meter, the arc gate control system 5 will issue a command to immediately open the ninth arc gate to 1 meter, and delay 60 seconds to open the tenth arc gate to 1 meter; after the ninth arc gate is opened to 1 meter, the first arc gate is opened to 1 meter; after the tenth arc gate is opened to 1 meter, the second arc gate is opened to 1 meter; after the first arc gate is opened to 1 meter, the third arc gate is opened to 1 meter; after the second arc gate is opened to 1 meter, the fourth arc gate is opened to 1 meter.

[0035] If the upstream water level rises too fast and directly rises to exceed the set height, the arc gate control system 5 orders to immediately open the fifth arc gate to an opening of 1 meter, and then open the sixth arc gate to an opening of 1 meter after an interval of 60 seconds; after the fifth arc gate is opened to an opening of 1 meter, open the seventh arc gate to an opening of 1 meter; after the sixth arc gate is opened to an opening of 1 meter, open the eighth arc gate to an opening of 1 meter; after the seventh arc gate is opened to an opening of 1 meter, open the ninth arc gate to an opening of 1 meter; after the eighth arc gate is opened to an opening of 1 meter, open the tenth arc gate to an opening of 1 meter; after the ninth arc gate is opened to an opening of 1 meter, open the first arc gate to an opening of 1 meter; after the tenth arc gate is opened to an opening of 1 meter, open the second arc gate to an opening of 1 meter; after the first arc gate is opened to an opening of 1 meter, open the third arc gate to an opening of 1 meter; after the second arc gate is opened to an opening of 1 meter, open the fourth arc gate to an opening of 1 meter.

[0036] When the reservoir arc gate 6 is opened according to the above settings, when the upstream water level drops below the set height, the arc gate linkage program exits, and the existing opening of the existing reservoir arc gate 6 is adjusted according to actual requirements;

[0037] By calculating the water level of the reservoir, a linkage relationship is established with the reservoir arc gate 6 to realize automatic opening of the arc gate to protect the safety of the dam;

[0038] When there are a lot of aquatic plants and mosses attached to the outer wall of the reservoir arc gate 6, the second motor 11 can be started to work. The second motor 11 drives the threaded rod 10 to rotate through a transmission belt. The transmission belt can be a chain, which cooperates with a sprocket to drive the threaded rod 10 to rotate. The threaded rod 10 is supported by the baffle 8 on the outer wall of the reservoir arc gate 6. The threaded rod 10 drives the cleaning strip 2 to move back and forth on the outer wall of the reservoir arc gate 6. The cleaning strip 2 can clean the outer wall of the reservoir arc gate 6 and clean out the aquatic plants and the like attached to the outer wall of the reservoir arc gate 6, so as to avoid damage to the reservoir arc gate 6 caused by the aquatic plants sticking to the outer wall when the reservoir arc gate 6 is opened, and at the same time avoid affecting the drainage.

[0039] like Figure 6As shown, there are three water level gauges 1, and the three water level gauges 1 are evenly distributed in the upstream reservoir; after receiving the signals of the three water level gauges 1, the computer monitoring system 3 performs three-mean logic processing, that is, each time the calculation is performed, three data with an interval of five seconds are taken for average calculation to prevent the fluctuation of a single water level gauge 1 from causing abnormal upstream water level measurement; the reservoir water level is calculated using the "three-mean" logic, and each time the calculation is performed, three data with an interval of five seconds are taken for average calculation to prevent water level fluctuations from affecting the calculation results; after the monitoring calculates the upstream water level, according to the actual regulation of the reservoir, different water levels are set to realize the control logic of automatic startup of the reservoir arc gate 6.

[0040] like Figure 2 , 3 As shown, there are three threaded rods 10, which are respectively located at the two ends and the middle of the two baffle bars 8.

The outer wall of the reservoir arc gate 6 is provided with a makeshift groove 7 for making way for the transmission belt connected between the multiple threaded rods 10; when the second motor 11 drives one of the threaded rods 10 to rotate, the threaded rod 10 drives the other threaded rods 10 to rotate synchronously through the transmission belt, and the makeshift groove 7 makes way for the transmission belt, so that the multiple threaded rods 10 rotate synchronously and drive the cleaning bar 2 to move, so that the cleaning bar 2 can stably clean the water plants and the like on the outer wall of the reservoir arc gate 6, thereby improving the strength and stability of the cleaning bar 2.

[0041] like Figure 1-5 As shown, there are two cleaning strips 2, and the cleaning unit 9 is located between the two cleaning strips 2; the two cleaning strips 2 move synchronously on the outer wall of the reservoir arc gate 6, which can achieve more thorough cleaning of the aquatic plants on the outer wall of the reservoir tiger gate 6 and improve practicality.

[0043] like Figure 4 , 5As shown, the cleaning unit 9 also includes a connecting frame 93, which is installed at the ends of the two cleaning strips 2, and a first motor 94 and a support plate 95 are installed on the connecting frame 93. One side of the support plate 95 and the output end of the first motor 94 are both rotatably connected with an adjusting disk 96, and an adjusting rod 97 is rotatably connected between the two adjusting disks 96. The outer wall of the connecting plate 91 is fixedly connected with two connecting blocks 98, and the other end of the adjusting rod 97 is rotatably connected between the two connecting blocks 98; when the threaded rod 10 drives the two cleaning strips 2 to move, the first motor 94 is started to work, and the first motor 94 is supported by the connecting frame 93, and the first motor 94 drives the adjusting disk 96 to rotate The two adjusting disks 96 are supported by the first motor 94 and the support plate 95 respectively. The two adjusting disks 96 drive the adjusting rod 97 to move. The adjusting rod 97 and the connecting block 98 rotate and move, thereby driving the connecting plate 91 to move. The connecting plate 91 drives the slider 13 to slide in the slide groove 12. The connecting plate 91 drives multiple brush heads 92 to move back and forth. In conjunction with the movement of the cleaning strip 2, the brush head 92 performs active cleaning of the outer wall of the reservoir arc gate 6. The use of the active brush head 92 can improve the cleaning of the outer wall of the reservoir arc gate 6, and avoid water plants, moss, etc. adhering to the outer wall of the reservoir arc gate 6, which affects the opening and closing of the reservoir arc gate 6 and the smoothness of the reservoir water discharge.

[0044] like Figure 5 As shown, multiple brush heads 92 are vertically distributed with the cleaning strip 2; when the brush heads 92 vertically distributed with the cleaning strip 2 move up and down on the connecting plate 91, the outer wall of the reservoir arc gate 6 can be better cleaned to improve practicality.

[0045] Implementation steps in this embodiment: according to the set water level start program, the water level of the upstream reservoir is measured by the water level meter 1, and the water level meter 1 uses a cable to transmit the water level signal to the computer monitoring system 3 in real time. The computer monitoring system 3 calculates the number and opening degree of the reservoir arc gates 6 that need to be opened at the current water level. After the calculation is completed, the computer monitoring system 3 first transmits the corresponding instructions to the arc gate communication machine 4, and after being transferred by the arc gate communication machine 4, it is transmitted to the arc gate control system 5 for command, and then the corresponding reservoir arc gate 6 is opened to the corresponding opening to prevent the arc gate from being flooded over the top; when there are more aquatic plants and mosses attached to the outer wall of the reservoir arc gate 6, the second motor 11 can be started to work, and the second motor 11 drives the threaded rod 10 to rotate through the transmission belt.
