Description

Technical Field

[0001] The invention relates to the technical field of ship engineering, and in particular to a method for creating operating conditions for opening a sluice. Background Art

[0002] The opening of a ship lock is an abnormal operating condition, but it can significantly improve the ship lock's capacity. It has broad application prospects in coastal or tidal river sections where water transportation is developed and the ship lock may have bidirectional head or low head conditions. Generally, the opening of the ship lock is not considered during the construction of the ship lock. Therefore, even under the low head condition of the ship lock, it is still difficult to achieve the opening operation conditions that facilitate the safe passage of ships. The traditional navigation wall guide part cannot well prevent the water flow of the first line of the pilot channel from flowing to the other line of the pilot channel, resulting in a local high water surface gradient in the navigation adjustment section of the ship lock; a steep drop area will be formed at the section between the ship lock chamber and the upper lock head. Under the opening condition, the flow velocity and water surface gradient in this area change dramatically. Ships need to face stronger water flow when passing through the gate, resulting in poor ship passage conditions. Therefore, how to reduce the large water surface gradient upstream and downstream of the hub needs to be further examined. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is: how to provide a method for creating operating conditions for opening a lock that can reduce the water surface gradient, improve the operating conditions for opening a conventional lock, and enhance the passing capacity of a lock.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: A method for creating conditions for opening a lock for operation. When the lock needs to be opened for operation, a temporary flow-blocking wall connected to the guiding wall is arranged on the river channel at one end of one or both guiding walls away from the ship lock along the length direction of the corresponding guiding wall toward the upstream of the river channel according to the respective lengths of the guiding walls on both sides of the upstream navigation channel, so as to extend the length of the upstream navigation channel; a temporary cushion layer is arranged at the upstream of the ship lock chamber, the width of the temporary cushion layer is consistent with the width of the ship lock chamber, and a gently descending slope is arranged on the temporary cushion layer, one end of which is connected to the bottom surface of the upstream navigation channel and the other end of which is inclined downward toward the downstream direction of the ship lock chamber to the bottom of the ship lock chamber.

[0005] In the present invention, the temporary flow-isolating wall extends the length of the navigation channel. Through the extended navigation channel, the water flow has a longer distance to be adjusted and stabilized before entering the ship lock. The longer navigation channel helps to slow down the water flow speed and reduce the water flow energy, thereby reducing the water surface gradient. The temporary cushion layer forms a transitional gentle slope between the navigation channel and the upstream of the ship lock chamber, thereby adjusting the previous steep drop section to a gentle slope section, which can significantly improve the local water surface gradient of the steep drop section of the lock chamber elevation.

[0006] As an optimization, the temporary cushion is made of flexible material, and is divided into several water-filled chambers. Two adjacent water-filled chambers are provided with interconnected water-filled holes. The ship lock is equipped with a cushion water-filling control device capable of filling and draining water in the temporary cushion. When the lock needs to be opened for operation, the temporary cushion is filled with water to form a slow-falling slope; when the lock is not opened for operation, the temporary cushion is pumped out to lower its height to avoid collision with the bottom of the ship.

[0007] As an optimization, the temporary flow-blocking wall includes a number of mooring piers arranged at intervals along the length direction of the guiding wall toward the upstream of the river channel, the upper ends of the mooring piers extend above the water surface of the river channel, and a water passage is formed between two adjacent mooring piers on the same side and between the guiding wall and its adjacent mooring piers. A water retaining device capable of controlling the closure of water flow is provided in the water passage. According to different operating conditions, the water passage is controlled, and the river water can pass through the water passage normally when the gate is not opened, which will not affect the flow conditions of the waterway.

[0008] As an optimization, the water retaining device includes a slide groove opened on the mooring piers located on both sides of the water passage and on the mooring piers and the guiding wall, the slide groove is a T-shaped groove and extends vertically, the two ends of the slide groove are respectively close to the upper and lower ends of the mooring pier and the guiding wall where they are located, a plurality of sliders are arranged in the slide groove, both of which can slide and cooperate with the slide groove in the vertical direction, the top of the mooring pier and the guiding wall and the positions of the slide grooves thereon are respectively pierced with rope holes connected with the slide groove in the vertical direction, the top of the mooring pier and the guiding wall and the positions of the rope holes are respectively installed with winch devices, a pull rope is wound on the winch device, one end of the pull rope away from the winch device passes through the corresponding rope hole and extends into the slide groove, the pull rope located in the slide groove passes through all the sliders located in the slide groove from top to bottom in sequence, the pull rope and the slider are arranged at a distance, the pull rope is located in the slide groove and a limit device that can abut against the slider is arranged below the bottom slider; the water retaining device also It comprises a water-filled curtain arranged in the water-passing channel, the top of the water-filled curtain is fixedly connected with a mounting bracket and is fixedly connected to the mooring pier and the guidance wall located above the water surface of the river channel through the mounting bracket, the water-filled curtain is made of flexible material, the interior of the water-filled curtain is divided into a plurality of water-proof chambers, and a connecting hole that is interconnected is arranged between two adjacent water-proof chambers, the mooring pier is also provided with a curtain water-filling control device that can fill and discharge water in the water-filled curtain, the two side edges of the water-filled curtain are respectively fixedly connected with connecting brackets at intervals in the vertical direction, the number of connecting brackets on the same side is consistent with the number of sliders, the connecting brackets extend into the slide slot and are rotatably connected with the corresponding slide slot; when the winch device unwinds the pull rope downward, the flexible hanging curtain can be unfolded downward and can block the water-passing channel where it is located, and when the winch device reels the pull rope upward, the pull rope can pull the slider upward through the limiting device so that the water-filled curtain can be folded above the water surface of the river channel. When the river channel needs to be blocked, the winch device unwinds the pull rope downwards, and when the slider is not limited by the limit device, it will slide downwards under the action of the gravity of the water-filled curtain, and the water-filled curtain will also unfold downwards toward the bottom of the river channel until the water-filled curtain is fully unfolded. The water-filled curtain can block the water passage and fill it with water to improve stability. When the ship lock is not in operation, there is no need for a temporary flow barrier. After the water in the water-filled curtain is pumped out, the winch device reels the pull rope upwards, and the limit device will abut against the lowest slider and push the slider upward. When the lower slider moves upward, it will abut against the upper slider, so that the upper slider can be driven to move upward together until all sliders abut against the upper end of the slide; while the lower slider moves upward, the water-filled curtain begins to fold upward from the lower end until it folds above the water surface of the river channel along with the slider.

[0009] Compared with the prior art, the present invention adds a temporary flow barrier wall on the auxiliary wall and adds a water-filled cushion layer in the lock chamber, which significantly improves the local water surface gradient of the steep drop section of the lock chamber, thereby significantly improving the operating conditions of the ship lock.
