Description

Technical Field

[0001] The utility model relates to the field of water gates, in particular to a water level measuring gate for a dam. Background Art

[0002] A sluice is a low-head hydraulic structure built on rivers and canals that uses gates to control flow and adjust water levels. Closing the gates can block floods, tides, or raise the upstream water level to meet the needs of irrigation, power generation, shipping, aquaculture, environmental protection, industry, and domestic water; opening the gates can discharge floods, waterlogging, abandoned water, or wastewater, and can also supply water to the downstream river or canal.

[0003] China's patent publication number CN214656840U discloses a gate for a water conservancy dam with a liquid level display. The utility model adds a float, a scale and a buzzer. When the water level rises, the float is driven to rise. The height of the liquid level can be understood from the scale indicated by the indicator rod, which is convenient for staff to understand the liquid level of the dam. When the liquid level is too high, the float drives the indicator rod to move up and squeeze the switch to realize the buzzer alarm, which is conducive to timely response by staff.

[0004] However, there are still the following disadvantages: when the gate is opened to release water, the support block and the scale line will be lifted together with the gate. Since the bottom of the scale line is at a certain distance from the bottom of the river channel, it is impossible to accurately monitor and observe the water level in real time, thereby reducing the practicality of the device.

[0005] Therefore, a water level measuring gate for a dam is proposed. Utility Model Content
