Specific implementation manner

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Refer to Figures 1 - 5 , a reservoir water level grading acousto-optic alarm device, including level gauge A1, level gauge B2, level gauge C3, three signal transmission cables 4, a computer monitoring system 5, an acousto-optic alarm 6, an operator station 7 and a mounting rack 8. The level gauge A1, level gauge B2, and level gauge C3 are respectively connected to the computer monitoring system 5 through the three signal transmission cables 4. The acousto-optic alarm 6 is installed inside the operator station 7. The computer monitoring system 5 is connected to the acousto-optic alarm 6 through a wire. The water level signal is transmitted to the computer monitoring system 5 in real time through the signal transmission cable 4. The mounting rack 8 is used for fixed installation inside the upstream reservoir.

[0022] Inside the mounting bracket 8, a support rod 9 is rotatably connected. On the outer surface of the support rod 9, three telescopic components 10 are fixedly connected. Each telescopic component 10 is composed of a cross-frame A101, a cross-frame B102, and a sleeve 103. The cross-frame A101 and the cross-frame B102 are both inserted into the sleeve 103. Inside each of the cross-frame A101 and the cross-frame B102, an installation hole A15 is provided. Inside the sleeve 103, an installation hole B16 is provided. Two groups of the installation holes A15 and two groups of the installation holes B16 are fixed by screws A and nuts A respectively, which is convenient for adjusting the telescopic length of the telescopic component 10. Furthermore, the positions of the liquid level gauge A1, the liquid level gauge B2, and the liquid level gauge C3 can be adjusted. Each telescopic component 10 can be telescoped. At one end of each telescopic component 10, an adjustment component 11 is rotatably installed. Each adjustment component 11 is composed of a mounting plate 111, a rotating column 112, and two brackets 113. Each rotating column 112 is rotatably connected to the cross-frame B102 adjacent to it and is also rotatably connected to the mounting plate 111. The mounting plate 111 is fixedly connected to the two brackets 113. Inside each bracket 113, a plurality of equally spaced installation holes C17 are provided. The two brackets 113 and the two connecting plates 12 are fixed by screws B and nuts B. When installing, it is used to slightly adjust the heights of the liquid level gauge A1, the liquid level gauge B2, and the liquid level gauge C3. On the bottom surface of each mounting plate 111, two symmetrically arranged gravity components 18 are fixedly connected. The bottom end of each gravity component 18 is spherical. When the telescopic component 10 is tilted, the gravity of the gravity component 18 can keep the positions of the liquid level gauge A1, the liquid level gauge B2, and the liquid level gauge C3 horizontal with the liquid surface, improving its measurement accuracy.

[0023] On the front surface of each adjustment component 11, two connecting plates 12 are installed. The liquid level gauge A1, the liquid level gauge B2, and the liquid level gauge C3 are respectively fixedly connected to the three groups of connecting plates 12. On the outer surface of the support rod 9, two worm wheels 13 are fixedly connected. On the left side surface of the mounting bracket 8, a power component 14 is installed. The power component 14 is composed of two fixing frames 141, two worm shafts 142, and two servo motors 143. The two servo motors 143 and the two fixing frames 141 are both fixedly connected to the mounting bracket 8. The two ends of the two worm shafts 142 are rotatably connected to the two fixing frames 141. The output ends of the two servo motors 143 are respectively fixedly connected to the upper ends of the two worm shafts 142. The two servo motors 143 can control the rotation of the two worm shafts 142, and thus control the rotation of the two worm wheels 13. When the two worm wheels 13 rotate, they can adjust the rotation of the three telescopic components 10, and thus can greatly adjust the heights of the liquid level gauge A1, the liquid level gauge B2, and the liquid level gauge C3, improving the adjustment speed. The power component 14 can control the rotation of the two worm wheels 13 to adjust the heights of the liquid level gauge A1, the liquid level gauge B2, and the liquid level gauge C3.

[0024] An operation method of a reservoir water level grading sound and light alarm device includes the following steps:

[0025] S1: Level gauges A1, B2, and C3 for measuring upstream water level data, and connecting this data to a computer monitoring system 5 through a signal transmission cable 4 for calculation, and transmitting the results to an operator station 7;

[0026] S2: Each time of calculation, take 3 data at intervals of 5 seconds for average value calculation;

[0027] S3: The operator station 7 displays the water level rising rate s and the remaining time t until the gate overflows (215.5 meters) in real time; t = (215.5 - upstream water level) / S, and the remaining time until the gate overflows (215.5 meters) can be calculated;

[0028] S4: When the reservoir water level is lower than 213.5 meters, calculate the water level rising rate s every 10 minutes. When the reservoir water level is higher than 213.5 meters, calculate the water level rising rate S every 5 minutes. The water level rising rate is finally converted to * meters per hour.

[0029] During use, during the installation process, the level gauges A1, B2, and C3 need to be installed at multiple installation holes C17 respectively. According to the situation of the upstream reservoir, the heights of the level gauges A1, B2, and C3 can be selectively adjusted slightly. By setting the telescopic assembly 10, it is convenient to adjust the positions of the level gauges A1, B2, and C3 according to requirements. When it is necessary to adjust the heights of the level gauges A1, B2, and C3 greatly, start two servo motors 143 to make two worm gears 142 rotate. The two worm gears 142 drive two worm wheels 13 respectively. The two worm wheels 13 can drive the support rod 9 to rotate more stably. The support rod 9 drives three telescopic assemblies 10 to rotate, and then the inclination angles of the three telescopic assemblies 10 can be adjusted, so that the heights of the level gauges A1, B2, and C3 can be adjusted greatly according to the actual situation of the reservoir.

[0030] Immediately afterwards, the liquid level gauges A1, B2, and C3 are mainly used to measure the water level of the upstream reservoir. The water level signals are transmitted to the computer monitoring system 5 in real time through the signal transmission cable 4. After the computer monitoring system 5 receives the signals from the liquid level gauges A1, B2, and C3, it calculates the average value by taking 3 data at intervals of 5 seconds each time to prevent abnormal measurement of the upstream water level caused by the fluctuation of a single liquid level gauge. When the reservoir water level is lower than 213.5 meters, the water level rising rate S is calculated every 10 minutes; when the reservoir water level is higher than 213.5 meters, the water level rising rate S is calculated every 5 minutes. The water level rising rate is finally converted to *m / hour. Through the formula: t = (215.5 - current water level) / S, the remaining time t for the gate to overtop (215.5 meters) can be calculated. When the remaining time t for the gate to overtop is 120 minutes, the operator station 7 reports a level 3 alarm of "Remaining time for the arc gate to overtop by water is 120 minutes", and through the computer monitoring system 5, the audible and visual alarm 6 in the central control room is activated to remind the duty personnel in the central control room to pay timely attention to the current water level. When the remaining time t for the gate to overtop is 90 minutes, the operator station 7 reports a level 2 alarm of "Remaining time for the arc gate to overtop by water is 90 minutes", and through the computer monitoring system 5, the audible and visual alarm 6 in the central control room is activated to remind the duty personnel in the central control room to pay timely attention to the current water level. When the remaining time t for the gate to overtop is 60 minutes, the operator station 7 reports a level 1 alarm of "Remaining time for the arc gate to overtop by water is 60 minutes", and through the computer monitoring system 5, the audible and visual alarm 6 in the central control room is activated to remind the duty personnel in the central control room to pay timely attention to the current water level. When the remaining time t for the gate to overtop is 30 minutes, the operator station 7 reports a level 1 alarm of "Remaining time for the arc gate to overtop by water is 60 minutes", and through the computer monitoring system 5, the audible and visual alarm 6 in the central control room is activated to remind the duty personnel in the central control room to pay timely attention to the current water level. The operator station 7 can display the remaining time t from the current water level to overtop the gate and the current water level in real time. The duty personnel in the central control room can conveniently view the corresponding data. When the remaining time t for the gate to overtop reaches the corresponding set program, a corresponding brief report will be shown on the screen of the operator station 7, and through the computer monitoring system 5, the audible and visual alarm 6 will be activated. Through the dual reminder of the brief report and the sound, the duty personnel are reminded to pay timely attention to the upstream water level to prevent the occurrence of the event of the reservoir water overflowing the dam.
