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. [Background technology]

[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.

[0003] The application (patent) number is: CN202110319085.X. A spillway armless working arc gate device, which is mainly composed of a gate body, an arc gate, an arc gate embedded part, a water seal device, an opening and closing and control device. Slide rails and opening and closing and control devices are arranged on the inner walls on both sides of the gate body. Guide wheels adapted to the slide rails are arranged on both sides of the arc gate. Guide rails are arranged on both sides of the arc gate. The transmission gear of the opening and closing and control device cooperates with the guide rail to drive the arc gate along the gate body. The inner wall rises or falls, and the water seal device is the key to the success of the arc gate system. The arc gate water seal includes side water seal and bottom water seal. Side water seal and bottom water seal are respectively arranged in the door tracks on both sides and the bottom of the arc gate, and the side water seal adopts L-shaped water seal, and the bottom water seal adopts strip water seal. Since there is sliding friction between the gate body and the side water seal when opening, it is easy to cause damage to the side water seal, affecting the normal service life; and since the opening and closing and control equipment require the application of electric energy, it is not conducive to use in remote areas of the wild, and thus has poor adaptability.

[0019] Working process of the present invention:

[0020] In the working process of a spillway gate device of the present invention, when the water level of the reservoir rises to the water inlet 8, water enters the water filling pipe and the pipe 1 from the water inlet 8 and fills them up, so that the flow rate of the water inlet 8 is greater than the outflow rate of the drain port III67. When the liquid level in the water filling pipe rises to the connecting pipe 65, water enters the cylinder body 61 above the piston body 62. As the amount of water inflow increases, the elongation force of the spring I643 is overcome, and the piston body 62 moves downward, pulling the anti-slip body 644 downward through the slide rod 642 to compress the spring I643. When 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 is pressed under the action of the air. The water on the top of the cylinder 61 expands upward and squeezes out the water therefrom into the cavity 44. At this time, the cover body 42 floats up and opens the drain port I2. When water enters the cylinder body 61, part of the water therein is discharged into the water collection tank 53 through the spring hose 63 and the drain port III 67 in turn. When a certain amount of water is reached, the water collection tank 53 moves downward and compresses the elastic support mechanism 54. At the same time, the water collection tank 53 drives the hook 57 to rotate counterclockwise through the cooperation of the connecting rod 55 and the U-shaped body 56, so that the hook 57 is separated from the corresponding shaft head 59. At this time, the force of the water pressure overcomes the force of the spring hinge 52, and the blocking cover 51 opens to drain water. When water enters the water collection tank 53, part of the water therein is discharged from the drain port II 58.

[0021] The diameter of the water inlet 8 is larger than the diameter of the connecting pipe 65 , the diameter of the connecting pipe 65 is larger than the diameter of the drain port III67 , and the diameter of the drain port III67 is larger than the diameter of the drain port II58 .

[0022] When the water level of the reservoir drops, when the flow rate entering the water filling pipe 3 from the water inlet 8 is less than the outflow rate of the drain port III67, the amount of water in the cylinder 61 decreases, and the anti-slip body 644 pulls the piston body 62 upward through the slide rod 642 under the action of the spring I643, and the air in the cavity 44 re-enters the cylinder 61, and at the same time, water enters the cavity 44 from the water outlet 46. The sealing cover body 42 after water injection blocks the drain port I2 by its own weight. Since there is no water pressure, the spring hinge 52 drives the sealing cover 51 to re-block the pipeline 1. As the water in the water collecting tank 53 is discharged, the water collecting tank 53 rises back to its original position under the action of the elastic support mechanism 54, and the water collecting tank 53 drives the hook 57 to rotate clockwise through the cooperation of the connecting rod 55 and the U-shaped body 56 so that it is hooked on the corresponding shaft head 59.

[0023] 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.
