Description

Technical Field

[0001] The utility model relates to the field of lifting dams, in particular to a multi-layer closed hydraulic lifting dam. Background Art

[0002] A hydraulic lifting dam, also known as a hydraulic concrete lifting dam, is a relatively simple movable dam technology in water conservancy science and technology. It is widely used in the construction of agricultural irrigation, fishery, ship locks, seawater tide protection, urban river landscape projects, small hydropower stations, etc. It can automatically lift the movable dam surface according to the rise and fall of floods. In the existing lifting dams, during the lifting process, the dam surface is set as a single plate. Since it is located between uneven water levels and is used for guiding flood discharge and tide protection, as the high water level guides to the low water level, due to the water pressure impacting the plate body and generating a backflow impact, it is subjected to double-sided pressure, which easily causes the dam surface to break and affects the overall protection effect. Therefore, we propose a multi-layer closed hydraulic lifting dam to solve the problems mentioned above. Content of the Utility Model

[0003] In order to overcome the problem that in the lifting dam, the dam surface is set as a single plate. As the high water level guides to the low water level, due to the water pressure impacting the plate body and generating a backflow impact, it is subjected to double-sided pressure, which easily causes the dam surface to break and affects the overall protection effect.

[0004] The technical solution of the utility model is: a multi-layer closed hydraulic lifting dam, which includes multi-layer closed dam plates, an electric control module hidden box, a steering sleeve, a sealing sleeve, a steering rod and a decompression and diversion module; the multi-layer closed dam plates are used to form a multi-layer closed structure to increase the water pressure bearing and protect the closed dam plates. The lower end of the multi-layer closed dam plates is fixedly connected with a steering sleeve for lifting and steering connection. The inside of the steering sleeve is provided with a steering rod for steering connection. A sealing sleeve coaxially arranged with the steering sleeve is sleeved on the steering rod for steering and closing protection. Behind the steering sleeve is an electric control module hidden box for forming a closed protection for the electric control elements of the dam plate hydraulic lifting. Multiple groups of decompression and diversion modules for preventing water pressure impact and guiding surface diversion are evenly arranged on the multi-layer closed dam plates.

[0005] Preferably, the multi-layer closed dam plates can be used to form a multi-layer closed structure to increase the water pressure bearing and protect the closed dam plates. Through the sealing sleeve, a sealing sleeve coaxially arranged with the steering sleeve is sleeved on the steering rod, which can be used for steering and closing protection. The electric control module hidden box is arranged behind the steering sleeve and can be used to form a closed protection for the electric control elements of the dam plate hydraulic lifting. Through the decompression and diversion modules, multiple groups are evenly arranged on the multi-layer closed dam plates, which can be used to prevent water pressure impact and guide surface diversion to ensure the overall protection effect.

[0006] Preferably, the multi-layer closed dam plate includes a wavy curved panel, a curved sealing strip, a central layer sealing plate, an extended closed sleeve plate, a slot, a plug, a curved closed bearing plate, a curved sealing corner sleeve, a floating electric control switch, a first hydraulic cylinder, a second hydraulic cylinder, a first hydraulic rod, a second hydraulic rod, an arc-shaped closed sleeve, an extended closed insertion plate and a first diversion hole. The wavy curved panel, the central layer sealing plate and the curved closed bearing plate are fixedly connected in a stacked manner from bottom to top. First diversion holes communicating with the decompression and diversion module are linearly arranged on both sides of the wavy curved panel. Extended closed sleeve plates and extended closed insertion plates are integrally formed on both sides of the central layer sealing plate respectively. Then, the plug on the extended closed insertion plate enters the slot on the extended closed sleeve plate, and a closed and open state is formed between two groups of multi-layer closed dam plates.

[0007] Preferably, curved sealing corner sleeves are arranged at the top and bottom edges of the wavy curved panel, and curved sealing strips are arranged at the side edges of the wavy curved panel. Through the curved sealing strips, corner sealing protection can be carried out.

[0008] Preferably, floating electric control switches are arranged at the top and bottom of the central layer sealing plate. An electric signal device and a water pressure sensor are arranged inside the floating electric control switch. A first hydraulic cylinder and a second hydraulic cylinder electrically connected to the floating electric control switch are linearly symmetrically arranged at the rear end of the curved closed bearing plate. The first hydraulic rod and the second hydraulic rod are respectively connected to the lower ends of the first hydraulic cylinder and the second hydraulic cylinder, so that the first hydraulic rod and the second hydraulic rod drive the multi-layer closed dam plate to perform lifting operations, and the synchronous steering sleeve steers along the steering rod.

[0009] Preferably, a slot is opened on the extended closed sleeve plate, and a plug corresponding to the slot is arranged on the extended closed insertion plate.

[0010] Preferably, the decompression and diversion module includes a diversion guide sleeve, a diversion space, a waterproof sealing fitting ring, a second diversion hole, a diversion hole and a diversion channel. A diversion space is opened in the center of the diversion guide sleeve. Second diversion holes communicating with the diversion space are opened on both side walls of the diversion guide sleeve. The diversion space and the second diversion holes can perform diversion operations.

[0011] Preferably, a waterproof sealing fitting ring is coated on the periphery of the diversion guide sleeve. A diversion hole is arranged at the bottom of the diversion space, and a diversion channel is arranged below the diversion hole. Through the waterproof sealing fitting ring, protective sealing can be carried out.

[0012] The beneficial effects of the present utility model:

[0013] 1. Different from conventional lifting dams with a single - panel dam surface, which are prone to surface breakage of the dam due to water pressure impacting the panel and resulting in backflow impact during the diversion from high water level to low water level, causing double - sided pressure on the dam surface and affecting the overall protection effect, the multi - layer enclosed dam plates are used to form a multi - layer enclosed structure for increased water pressure bearing and protection of the enclosed dam plates. Through the sealing sleeve, a sleeve coaxial with the steering sleeve is sleeved on the steering rod for steering and closing protection. The electric control module hidden box is arranged behind the steering sleeve to form a closed protection for the hydraulic lifting electric control components of the dam plates. The pressure - reducing and flow - splitting modules are evenly distributed on the multi - layer enclosed dam plates in multiple groups to prevent water pressure impact and conduct surface flow diversion, ensuring the overall protection effect.

[0014] 2. When in use, multiple groups of multi - layer enclosed dam plates are arranged horizontally. The electric control module hidden box drives the first hydraulic cylinder and the second hydraulic cylinder, so that the first hydraulic rod and the second hydraulic rod drive the multi - layer enclosed dam plates to perform lifting operations. Synchronously, the steering sleeve rotates along the steering rod, and then the insertion blocks on the extended closing plate enter the slots on the extended closing sleeve plate. A closed and open state is formed between the two groups of multi - layer enclosed dam plates. The sealing sleeve provides steering and closing protection. As the water flow impacts the corrugated panel, the concentrated water flow impact is reduced due to the undulating wave state. Using the diversion space and the flow - splitting channel, a part of the impact water flow can be diverted, and the impact momentum is split respectively through the first flow - splitting hole and the second flow - splitting hole. The central - layer sealing plate and the curved - type closing bearing plate are fixedly connected in sequence from bottom to top to form a multi - layer enclosed protection.
