Description

Technical Field

[0001] The invention relates to the technical field of water conservancy projects, in particular to the technical field of a spillway gate device with adjustable reservoir water storage capacity. Background Art

[0002] The spillway is a flood control device for water conservancy structures such as reservoirs. It is mostly built on one side of the dam, like a large trough. When the water level in the reservoir exceeds the safety limit, the water flows downstream from the spillway to prevent the dam from being destroyed. Flood discharge mechanisms are often required on the spillway. Due to continuous heavy rainfall, the reservoir exceeds the water level. In order to avoid flooding or the collapse of the reservoir dam and dike and cause serious disasters, the gates are opened to drain water to the downstream flood discharge area. During the flood season every year, the water levels of rivers, lakes, ponds and reservoirs rise, and the resulting floods pose a threat to the safety of river cities. In order to reduce the threat of floods to cities, it is necessary to discharge floods downstream in a timely manner, so flood discharge structures are needed to discharge floods.

[0016] Working process of the present invention:

[0017] In the working process of the spillway gate device with adjustable water storage capacity of the reservoir of the present invention, when the liquid level of the reservoir rises to the connecting pipe 65, water enters the cylinder body 61 above the piston body 62 through the connecting pipe 65, and part of the water is discharged through the drain pipe 63. As the amount of water entering increases, the elongation force of the spring 643 is overcome, and the piston body 62 moves downward to pull the anti-detachment body 644 downward through the slide rod 642 to compress the spring 643. While the piston body 62 moves downward, the air in the cylinder body 61 below it is pressed into the cavity 44, and the flexible diaphragm 45 expands upward under the action of the air to squeeze the water above it out of the cavity 44. At this time, the buoyancy of the cover body 42 itself plus the upward pulling force of the counterweight body 415 through the pull rope 414 causes the cover body 42 to float up and open the drain port 2 to drain water.

[0018] When the water level of the reservoir drops, the flow rate entering the piston body 62 from the connecting pipe 65 is less than the outflow rate of the drain pipe 63, and the amount of water in the cylinder body 61 decreases. Under the action of the spring 643, the anti-detachment body 644 pulls the piston body 62 upward through the slide rod 642, and the air in the cavity 44 re-enters the cylinder body 61. At the same time, water enters the cavity 44 from the water outlet 46. After the water is filled, the sealing cover body 42 blocks the drain outlet 2 by its own weight.

[0019] The larger the opening amount of valve 67, the larger the amount of water entering connecting pipe 65 is required, so that piston body 62 can descend through the increasing amount of water in cylinder body 61, which requires the water level of the reservoir to rise to a certain height so that the amount of water entering connecting pipe 65 is greater than the outflow amount of drain pipe 63. The larger the opening amount of valve 67, the more water storage capacity of the reservoir, and vice versa.

[0020] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention belongs to the protection scope of the present invention.
