Description

Teaching device and operation method for simulating sluice gates and pumping stations

The present invention relates to a teaching device for simulating sluice gates and pumping stations and an operating method thereof. In particular, it relates to a teaching device and an operation method for simulating sluice gates and pumping stations that are both convenient for water conservancy disaster prevention teaching and the teaching device is simple and easy to make. method.

The Chianan Plain in western Taiwan has gentle terrain and heavy rainfall in summer. Especially in recent years, global warming has caused abnormal post-climate conditions to become more serious. If there are heavy rains or typhoons in low-lying areas of the plains, all the rainfall will flow into the lower rivers, easily causing flooding.

Regarding the typical plain terrain in the Chianan Plain of Taiwan, the southwest corner of Dapi Township in Yunlin County is used as an example. Figure 8 is a simplified schematic diagram. It shows a main drainage channel 91, an embankment 92 (as shown by the imaginary line in Figure 8), a primary drainage channel 93 (the "Yantan Pai" flowing from north to south within the embankment 92), and in The embankment 92 also has a detention pond 94, a regulating pond 95, a pumping station 96, a first water gate G1, a second water gate G2 and a regulating pond water gate G3. The first water gate G1 is between the main drainage channel 91 and the secondary drainage channel 93 (as shown in Figure 9), and the second water gate G2 is between the secondary drainage channel 93 and the regulating between the pond 95; the regulating pond water gate G3 is between the detention pond 94 and the regulating pond 95. In addition, the water pumping station 96 is used to forcefully pump water from the regulating pool 95 into the main drainage channel 91 .

The above water conservancy facilities have the following three operating modes:

[a] Normal mode: Refer to Figure 10. Since the water level of the main drainage channel 91 is relatively low (for example, a first water level height H1), the first sluice gate G1 is open (ON), so that the secondary The water in the drainage channel 93 can be drained by gravity from high to low and flow into the main drainage channel 91 . In addition, the flood detention Both the pool 94 and the regulating pool 95 are at low water levels, so the pumping station 96 does not need to be started. The second water gate G2 remains closed.

[b] Flooding mode: Refer to Figure 11, when in a heavy rain or typhoon state, a large amount of rainfall causes the water level of the main drainage channel 91 to rise (for example, the second water level height H2, which is almost the same as the first water level H1 equal height or higher), so that the water in the secondary drainage channel 93 cannot be drained by gravity, and the main drainage channel 91 may even flow back toward the secondary drainage channel 93! Therefore, the first water gate G1 must be switched to a closed state (OFF) to prevent the water in the main drainage channel 91 outside the embankment 92 from pouring back into the embankment 92 (that is, the secondary drainage channel 93).

At the same time, since the water in the secondary drainage channel 93 in the embankment 92 may continue to increase, the second sluice gate G2 must be switched to an open state (ON) to allow the water in the secondary drainage channel 93 in the embankment 92 to It can flow into the regulating pool 95 instead.

[c] Pumping station startup mode: Refer to Figure 12. When the water level of the regulating pool 95 rises, the pumping station 96 may be activated according to the situation to force the water in the regulating pool 95 to the main water outside the embankment 92. in the drainage channel 91 to avoid flooding in the embankment 92.

However, since the operation of the above water conservancy facilities is only understood by professional water conservancy personnel, the general public (especially junior high school students and elementary school students) cannot experience and learn, which is really a big shortcoming.

In view of this, it is necessary to develop technology that can solve the above conventional shortcomings.
