[0027] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0028] like Figures 1 to 5 As shown, an embodiment of the present application provides an estuary moisture-proof system, including: a rotating gate mechanism 1, located in the middle of a river channel 2, the rotating gate mechanism 1 including a rotating drive assembly 11 and a rotating gate 12, the rotating drive assembly 11 being connected to the rotating gate 12, the rotating drive assembly 11 driving the rotating gate 12 to rotate to achieve its opening and closing; at least two lifting gate mechanisms 3, the two lifting gate mechanisms 3 being located on opposite sides of the rotating gate mechanism 1, the two lifting gate mechanisms 3 being arranged close to two river banks of the river channel 2, the lifting gate mechanism 3 including a lifting drive assembly 31 and a lifting gate 32, the lifting drive assembly 31 being connected to the lifting gate 32, the lifting drive assembly 31 driving the lifting gate 32 to lift and lower to achieve its opening and closing.

[0029] The embodiment of the present application adopts the combination of the lifting gate mechanism 3 and the rotating gate mechanism 1 to avoid the high cost of the estuary moisture-proof system. Since the rotating gate mechanism 1 includes a rotary drive component 11 and a rotating gate 12, the rotary drive component 11 can drive the rotating gate 12 to rotate, and the rotating gate 12 opens when the rotary drive component 11 drives the rotating gate 12 to rotate below the riverbed elevation. At low tide, both the rotating gate 12 and the lifting gate 32 are opened, and the middle of the river channel 2 is used for navigation. Since the rotating gate 12 can be rotated and hidden below the riverbed when it is opened, it will not affect the navigation of ships, avoiding the defect that the lifting gate 32 is not high enough to limit the navigation of large ships.

[0030] In one embodiment, there are two rotating gate mechanisms 1 and two lifting gate mechanisms 3 . The two rotating gate mechanisms 1 and the two lifting gate mechanisms 3 are arranged along the width direction of the river channel 2 , and the two rotating gate mechanisms 1 are located between the two lifting gate mechanisms 3 .

[0031] The two rotating gate mechanisms 1 are arranged between the two lifting gate mechanisms 3. When the two rotating gates 12 are opened, the navigation of large ships will not be affected. In addition, since the cost of the rotating gates 12 is higher, the lifting gate mechanism 3 is arranged near the river bank, which can minimize the cost of the entire estuary moisture-proof system without restricting the navigation of ships.

[0032] In order to realize the rotation of the revolving gate 12, the rotation driving assembly 11 includes a swing hydraulic cylinder 110 and a swing beam 111. A connecting rod is connected to the piston rod of the swing hydraulic cylinder 110, and the connecting rod is connected to the swing beam 111, and the swing beam 111 is connected to the revolving gate 12. In one embodiment, the swing beam 111 is connected to a chain rod pinned to the revolving gate 12.

[0033] When the rotating gate 12 needs to be rotated in this embodiment, the swing hydraulic cylinder 110 is started, and the swing hydraulic cylinder 110 drives the swing beam 111 to swing through the connecting rod, and the swing beam 111 drives the rotating gate 12 to rotate. The connection between the swing beam 111 and the connecting rod forms a hinge point, and the swing beam 111 can swing around the hinge point. Preferably, the rotating gate 12 is an arc-shaped gate.

[0034] In order to realize the lifting and lowering of the lifting gate 32, the lifting drive assembly 31 includes a support frame 310, a winch 311 and a chain 312. The bottom of the support frame 310 is fixed to the riverbed, the winch 311 is fixed to the top of the support frame 310, one end of the chain 312 is fixed to the drum of the winch 311, the chain 312 is extended or retracted as the drum rotates, and the other end of the chain 312 is connected to the lifting gate 32. When the winch 311 drives the chain 312 to extend, the lifting gate 32 is lowered to realize the closing of the lifting gate 32, and when the winch 311 drives the chain 312 to retract, the lifting gate 32 is raised to realize the closing of the lifting gate 32.

[0035] In one embodiment, in order to facilitate the lifting and lowering of the lifting gate 32, a slide groove may be provided on the support frame 310, and a slide rail may be provided on the lifting gate 32. The slide rail is slidably connected to the slide groove, and the slide rail slides in the slide groove when the lifting gate 32 is lifted or lowered.

[0036] In this embodiment, there are two lifting drive assemblies 31, which are respectively connected to the lifting gate 32, and the lifting gate 32 is simultaneously driven to rise and fall by the two lifting drive assemblies 31. In order to realize the connection between the chain 312 and the lifting gate 32, a connecting ring 33 is welded on the top of the lifting gate 32, and the chain 312 is connected and fixed to the connecting ring 33.

[0037] The lifting gate mechanism 3 further includes a roller 34 , which is disposed above the lifting gate 32 , and the other end of the chain 312 passes through the roller 34 and is connected to the lifting gate 32 .

[0038] The lifting gate mechanism 3 further includes a locking assembly 35, which is located on the support frame 310 and is used to lock the chain 312. The locking assembly 35 can be any locking assembly 35 currently used to lock the chain 312. For example, the locking assembly 35 can be a locking pin, which can be inserted into a link of the chain 312 to fix the position of the chain 312.

[0039] In one embodiment, the estuary moisture prevention system further includes a tidal power generation device 4, which is located at the downstream side of the lifting gate mechanism 3. After the lifting gate 32 is raised, the tidal power generation device 4 uses tidal energy to generate electricity. The tidal power generation device 4 is an existing tidal power generation device 4, and its structure and working principle are all existing technologies.

[0040] The estuary moisture prevention system further includes a liquid level gauge 5, which is located at the downstream side of the lifting gate mechanism 3, and the liquid level gauge 5 is located between the tidal power generation device 4 and the lifting gate mechanism 3. Preferably, the liquid level gauge 5 is a guided wave radar liquid level gauge, and the guide rod of the guided wave radar liquid level gauge is arranged in the vertical direction. The water level change of the estuary is monitored by the liquid level gauge 5.

[0041] In one embodiment, the estuary moisture-proof system further includes a laser radar, which is arranged on the upstream side and / or downstream side of the rotating gate mechanism 1. The estuary moisture-proof system further includes a camera, which is arranged on the upstream side and / or downstream side of the rotating gate 12. Preferably, the laser radar can be arranged on the upstream side of the rotating gate 12, and the camera can be arranged on the downstream side of the rotating gate 12; the laser radar and the camera can also be arranged on both the upstream side and the downstream side of the rotating gate 12.

[0042] The estuary moisture-proof system of this embodiment is arranged at the estuary. At low tide, the revolving gate 12 and the lifting gate 32 are opened. The opened revolving gate 12 is used for navigation. After the lifting gate 32 is opened, the tidal power generation device 4 behind it is used to generate electricity. At high tide, both the revolving gate 12 and the lifting gate 32 are opened to prevent the invasion of tide.

[0043] The rotary drive assembly 11 of the revolving gate mechanism 1 can drive the revolving gate 12 to rotate, so that the revolving gate 12 rotates below the riverbed elevation, without affecting the navigable water depth. When the revolving gate 12 is driven by the rotary drive assembly 11 to rotate upward 90 degrees, the revolving gate 12 is closed; when the revolving gate 12 is in the closed state, the rotary drive assembly 11 can also drive the revolving gate 12 to rotate upward another 90 degrees, so that the revolving gate 12 is suspended in the air, so as to facilitate the inspection and maintenance of the revolving gate 12.

[0044] The estuary tide prevention system of this embodiment not only solves the threat of tide and sea level rise in the estuary area, but also solves the problem of traditional gates restricting ship navigation through the rotating gate 12. The rotating gate 12 can be hidden under the riverbed when opened, and the rotating design also solves the problem of complicated gate maintenance process.

[0045] In one embodiment, the estuary tidal system can be controlled by a PLC system to achieve automated moisture prevention and navigation management, use a liquid level meter 5 to monitor the water level changes at the estuary in real time, use a laser radar and a camera to identify the location, size and passage time of the ship in real time, and then combine the tidal rise and fall time and height changes, monitor rainfall and storm surge water increase through meteorological data, and automatically open and close the lifting gate 32 and the rotating gate 12.

[0046] It should be noted that the use of laser radar and cameras to identify the position, size and passage time of ships in real time are both existing technologies, and the PLC control system is also an existing technology.

[0047] In order to fix the rotating gate mechanism 1 and the lifting gate mechanism 3, concrete piles can be built on the riverbed, and the rotating drive assembly 11 of the rotating gate mechanism 1 and the lifting drive assembly 31 of the lifting gate mechanism 3 can be fixed on the concrete piles.
