Side opening type water storage gate dam

Abstract

The novel side opening type water storage gate dam (hereinafter referred to as a gate dam) is mainly composed of a dam foundation, a side dam, a middle dam, a dam crest, flashboards, hinges (connected with the flashboards), bolts, (right-angle) fan-shaped guide rails, extension arms, rotating wheels and related components and facilities. The side embankment is stably connected with the embankment and extends upwards (downwards) to form a sightseeing footpath; the middle dike is upwards (extending) provided with a partition wall along the river; the partition wall divides the water storage area into two parts from the middle, half of water storage can be reserved in the flood period, and the half of all the flashboards are released for flood prevention. In rainy seasons, the gap of flood can be utilized to close the gate for water storage, and the gate dam can also utilize the stored water for power generation. The flashboards comprise an upper flashboard, a middle flashboard and a lower flashboard which are strip-shaped, and the forward water retaining surface slightly bulges; one end of the flashboard is connected with the middle dike through a hinge, and the other end is controlled to open and close through a bolt pin installed on the side dike.

Description

Technical Field

[0001] It belongs to the field of water conservancy engineering technology. Background Technology

[0002] In small and medium-sized rivers within or near urban areas, building dikes and dams for water storage is the preferred method for creating and upgrading the local ecology and tourism, and it can also optimize the local ecological environment. However, due to the need for flood control during the rainy season, even if water storage gates and dams are built on the rivers, they cannot be closed to store water during the rainy season. For more than half the year, there is water that cannot be used, nor can it be used, or rather, water that can be stored cannot be stored when it is available (during the rainy season); once the rainy season is over, the river is dry, or the flow is already very low. All the constructed gates and dams are rendered useless during this period, watching helplessly as the river water flows away. Due to the impact of flash floods, some areas even experience water shortages. The key reason is that the current gates are all bottom-up lifting gates, offering only two completely different functional choices: opening the gates to release all water or closing them to store water. When the rainy season arrives, for the need for flood control, the only solution is to open the gates wide to allow the floodwaters to pass. Summary of the Invention

[0003] A new type of side-opening water storage dam is characterized by its side-mounted connection and opening / closing mechanism, enabling rapid opening without the need for pre-emptive full gate opening for flood control. Even during peak flood seasons, the gates can be quickly opened to release floodwaters. It can also store water during the rainy season, requiring only partial gate opening for flood control. The new side-opening water storage dam (hereinafter referred to as the dam) mainly consists of: dam foundation, side dikes, central dike, dam crest, gate plates, hinges (connecting the gate plates), bolts, (right-angle) sector-shaped guide rails, extension arms, impellers, and related components and facilities. The dam foundation serves as the foundation for the dam; the dam foundation, side dikes, and central dike are the main engineering structures constructed of reinforced concrete; the side dikes and central dikes connect to the gate; the gate is elongated, with a slightly bulging forward side for water blocking, one end connected to the central dike by a hinge, and the other end controlled by a bolt installed on the side dike; the gate should not be too heavy overall, and must be made of lightweight metals such as aluminum alloy, preferably using high-strength aluminum alloy profiles welded together to form a frame, with a thin stainless steel plate welded to the outside of the frame; the overall structural strength of the hinges should be strengthened by, for example, by thickening the central axis; concave ends should be added to both sides of the gate. The steel profile increases the strength of both ends of the gate. An extension arm is installed at one end of the gate, and a wheel is installed under the extension arm. The wheel rotates along a (right-angle) sector-shaped guide rail. The (right-angle) sector-shaped guide rail unfolds with the hinge axis as the center. The bolt consists of a latch, spring, connecting shaft, etc. Two bolts are connected in parallel by a connector and a pull rope. Pulling the rope drives the connector to open the bolt synchronously. Pulling the pull rope opens the gate. The latch is reset by the spring. The bolt can be opened by two methods: sleeve and lever. The sleeve consists of three pipes (of different lengths) staggered to each other. The lower end of the pipe is tied with a ring to the rope end. The sleeve reaches the control room. Rotating the pipe drives the latch to open, controlling the opening of the three gates respectively. The lever is a set of levers. A fixed pulley guides the steel rope to rotate upward and then connects to the lever to control the bolt.The tops of the side and central dikes are paved with bridge decks, facilitating dam maintenance and serving as convenient bridges connecting the two banks. The side dikes connect firmly to the riverbanks and extend upstream (downstream) as sightseeing walkways, equipped with sturdy railings to prevent flooding. The central dikes are built to shorten the span of the dam (if too large). Depending on the riverbed width, more than one central dike can be constructed. Each central dike has two gates on each side, and two central dikes can have three gates. The central dikes extend forward and form a right-angled fan shape with the closed dam. A right-angled fan-shaped guide rail is installed, which lifts one end of the gate to reduce the torque on the hinge and solves the problem of excessive span of a single gate. Two pillars are built in the middle of the right-angled fan-shaped guide rail (for reinforcement). A partition wall is set up along the river from the middle dike. The partition wall divides the water storage area in half, with one half for water storage and the other half for flood control during the flood season. The partition wall is built with river pebbles and cement mortar, with a height equal to half that of the side dike. A cement slab is laid on top, and solid railings are built on both sides to serve as a walkway. At the end of the partition wall, two simple gates are set on the left and right sides. A wooden board is inserted into one gate to deflect the water and block the flow, facilitating the dam to close. After the gate is closed, the gate is opened and the other gate is closed, so that one side begins to store water while the other side is closed or opened as a flood discharge channel. The simple water-blocking gate can be removed at other times. During the flood season, half of the water can be stored while the other half is fully opened for flood control. During the rainy season, the gates can be closed to store water during the intervals between floods, and the dam can also use the stored water for power generation.

Cement board is laid on the top, and solid guardrails are built on both sides, which can be used as a walkway; two (15) simple gates are set on the left and right sides with the (13) partition wall as the boundary. A wooden board is inserted into one gate to divert the water and block the water flow, which is convenient for the gate to close. After the gate is closed, the gate is opened and the other gate is closed to start water storage. The other side is closed (or flood discharge is started). The simple water-blocking wooden board can be removed when not in use. During flood season, half of the water can be stored, and the other half (7) can be fully opened to prepare for flood control. For example: Appendix Figure 1 (7) The gate consists of three parts: upper, middle, and lower. It is long and narrow, with the front side slightly bulging to block water (see attached). Figure 3(7) One end of the gate is connected to the (2) middle dike with (8) hinge, and the other end is controlled by (9) bolts installed on the (3) side dike; (7) The gate should not be too heavy as a whole.
