Description

Technical Field

[0001] The invention belongs to the field of water conservancy engineering and tidal protection, and in particular relates to a buoyancy box telescopic gravity tidal gate. Background Art

[0002] With global climate change, sea level rise, frequent extreme weather and other disasters have intensified the challenges of flood control and tide prevention in coastal areas. Traditional flood control walls and tide barriers are difficult to meet current needs, and are even more affected by multiple pressures at the confluence of rivers and seas. Therefore, the need to build estuary tide gates is becoming more urgent.

[0003] In the existing technology, the design and construction of tide gates have made certain progress, but there are still some problems. Especially on navigable rivers, due to the navigation requirements of giant ships, single-span tide gates must have the characteristics of ultra-large span and ultra-high clearance. The ultra-large span tide gate structure system needs to withstand the resistance brought by the river flow when in use, and the force transmission path should be as short and direct as possible to minimize the deadweight and optimize the force distribution, thereby improving the rigidity and stability of the structure and ensuring the safety and reliability of the structure.

[0004] A buoyant bionic miter gate tide-blocking gate is disclosed in the patent with publication number CN113897916A, comprising: a gate pier; a receiving cavity is opened on one side of the gate pier, and a buoyant bionic gate is rotatably installed on one side wall of the receiving cavity through an installation component; two buoyant bionic gates and gate piers are each provided with; the buoyant bionic gate comprises two end portions, two transition sections and a mid-span section; the two end portions are respectively integrally formed with the two ends of the mid-span section through two transition sections; the cross-sectional widths of the end portions, the transition sections and the mid-span section are determined according to the magnitude of the bending moment they bear; the buoyant bionic gate comprises a first state, in which the two buoyant bionic gates are parallel to each other and are respectively placed in the two gate piers; the buoyant bionic gate comprises a second state, in which one end of the two buoyant bionic gates are respectively arranged in the gate pier, and the other ends contact each other to form a miter gate structure.

[0005] The gate disclosed in the above patent needs to withstand great resistance when opening and closing, consumes a lot of energy, and cannot be opened and closed quickly, which affects shipping and cannot be opened and closed in time; therefore, how to provide a pontoon telescopic gravity tide-blocking gate is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0006] The main purpose of the present invention is to provide a floating box telescopic gravity tide-blocking gate to solve the above technical problems. The device utilizes the telescopic characteristics of the gate body telescopic box and, with the help of a driving device, realizes the flexible telescopic, stable tide-blocking and efficient storage of the gate body telescopic box, and at the same time utilizes a docking device to assist the rapid closing and separation of the gate body telescopic box, thereby realizing the closing and separation of a large-span gate.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A floating box telescopic gravity-type tide-blocking gate comprises a power generation box fixed on both sides of the shore, the two power generation boxes are respectively connected to one end of the gate body telescopic box, the other ends of the two gate body telescopic boxes are connected by a docking device, the two gate body telescopic boxes are both provided with a driving device, the output end of the driving device abuts on the docking device, and the gate body telescopic box is controlled to be telescoped by the driving device, and a gate bottom plate is also provided between the bottom ends of the two power generation boxes, and the gate bottom plate is used to connect the gate body telescopic box.

[0009] Furthermore, the gate bottom plate includes a connecting plate and a track. The connecting plate is provided with tracks on both sides for blocking water. Both ends of the connecting plate are respectively connected to the power generation box bodies on both sides of the shore, and the bottom end of the gate body telescopic box is in contact with the track.

[0010] Furthermore, the connecting plate is a stepped connecting plate, and the connecting plate is adapted to the bottom end of the gate body telescopic box.

[0011] Furthermore, the gate body telescopic box is composed of a plurality of telescopic shells which are nested with each other, and a limiting device is arranged on each of the telescopic shells. The bottom ends of the two power generation boxes are connected through a gate bottom plate, and partitions are arranged between the telescopic shells in the gate body telescopic box, and corresponding holes are arranged on the partitions. The output end of the driving device is fixed to the docking device through the hole, and a gravity adjustment component is arranged inside the telescopic shell. Panel beams and ribs are arranged on both sides of the telescopic shell for water blocking, and an inner concave slot adapted to the track is arranged at the bottom end of the telescopic shell.

[0012] Furthermore, the gravity adjustment component includes a drainage pipe, an inflation pipe, an air pump and an air bag. The air pump is connected to the air bag through the inflation pipe. A valve is also provided on the inflation pipe. One end of the drainage pipe is connected to the air bag, and the other end is connected to the outside of the telescopic shell.

[0013] Furthermore, the panel beam is in a broken line shape.

[0014] Furthermore, the driving device is a hydraulic driving device.

[0015] Furthermore, a plurality of water passages are arranged in the power generation box, and a water turbine unit is arranged on the water passages.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention realizes flexible extension and retraction, stable moisture-proofing and efficient storage of the gate body telescopic box through the telescopic characteristics of the gate body and with the help of a driving device. At the same time, a docking device is used to assist the rapid closing and separation of the gate body telescopic box, thereby realizing the closing and separation of a large-span gate.

[0018] In addition, the gravity adjustment component realizes the low-energy sinking and floating operation of the gate telescopic box, significantly reducing energy consumption, and uses clean energy throughout the process without any pollutant emissions. At the same time, the shore tidal power generation turbine unit is used to supply clean and renewable energy for the opening and closing of the gate, without the need for additional energy consumption, which has effectively promoted the process of energy conservation, emission reduction and ecological environment protection.

[0019] 2. Innovative and environmentally friendly tide-blocking gate: The ultra-large-span tide-blocking gate telescopic box in the present invention has achieved the minimization of the floor space with its compact structural design, thereby minimizing the interference with the surrounding ecological environment during construction and operation. Only the gate bottom plate and track need to be constructed at the bottom of the river, and the construction area is effectively controlled, further reducing the damage to the natural ecology. In addition, when the gate telescopic box is in operation, its low-impact and high-efficiency characteristics ensure harmonious coexistence with the surrounding environment, fully reflecting the eco-friendly design concept.

[0020] 3. Innovative anti-siltation mechanism: The present invention specially designs a simple track system for the gate telescopic box. When the gate needs to block the tide or perform maintenance, it can move along the upward protruding track. This design utilizes the natural characteristics of water flow, making it difficult for silt and sediment to accumulate under and around the gate telescopic box. As the gate telescopic box rises, the silt that may have been deposited is naturally washed away by the water flow, thereby effectively preventing the problem of silt accumulation.

[0021] 4. Enhanced structural stability: The gate body telescopic box of the present invention has a built-in gravity adjustment component. After the splicing is completed, the gate body telescopic box is pumped out and filled with water to make it sink quickly and close to the riverbed gate bottom plate to form a tide-proof structure. In this process, the gate body telescopic box not only utilizes its own weight and shape stability, but also increases additional anti-slip force by filling with water. A more stable contact surface is formed between the gate body telescopic box and the gate bottom plate after being filled with water, which effectively resists the huge impact force and lateral slip risk brought by tides and floods, and can effectively transfer the loads generated by tides and waves to the gate bottom plate (i.e., the riverbed), significantly shortening the force transmission path and reducing the overall deflection, ensuring the safety and reliability of the structure.

[0022] 5. Optimize the structural design to ensure safe operation: The gate system design of the present invention incorporates considerations of dynamic characteristics and the principle of mechanical balance. By adopting a telescopic operation mechanism, the operation resistance is effectively reduced, thereby ensuring that the gate can be opened and closed smoothly during the opening and closing operation. By adopting a structural design of high-strength materials and a zigzag panel beam, the gate body telescopic plate of the present invention can maintain minimal deformation when subjected to huge pressures such as conventional tides and storm surges, thereby ensuring the stability and safety of the structure.

[0023] 6. Minimize construction occupation and worry-free shipping: During the construction period, the gate system of the present invention only needs to occupy a small amount of water space for the construction of the gate bottom plate, and the gate module can be pre-produced and tested in the factory, and then directly transported to the site for installation. In view of the large area of ​​land resources occupied by the horizontal arc tide gate, the gate system of the present invention has a retractable feature during operation to reduce the occupied area and reduce the occupation of the waterway and the space on both sides.

[0024] 7. Adaptability and scalability: The gate system of the present invention has high adaptability and scalability, can be customized and optimized according to the actual conditions of different waters, meet diverse needs, and can continuously adapt to new application scenarios and technical requirements.

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] like Figures 1 to 13 As shown, the present invention provides a floating box telescopic gravity tide-blocking gate, including a power generation box 2 fixed on the shores on both sides, the two power generation boxes 2 are respectively connected to one end of the gate body telescopic box 1, and the other ends of the two gate body telescopic boxes 1 are connected through a docking device 5. The two gate body telescopic boxes 1 are both provided with a driving device, the output end of the driving device abuts on the docking device 5, and the gate body telescopic box 1 is controlled to be telescopic by the driving device. A gate bottom plate is also provided between the bottom ends of the two power generation boxes 2, and the gate bottom plate is used to connect the gate body telescopic box 1. The gate body telescopic box 1 is made of lightweight and high-strength material. The cross-section of the gate body telescopic box 1 is designed to be trapezoidal or triangular to increase stability, and the interior of the gate body telescopic box 1 is divided into multiple areas, including an air bag area for buoyancy and a water-filled area for adjusting weight; the docking device 5 specifically uses an electrified strong magnetic centering strip in this embodiment, which can change the positive and negative poles and use attraction and repulsion to quickly close or separate the gate body telescopic boxes 1 on both sides; a garbage recovery tray can also be set on the gate body telescopic box 1 for cleaning the river channel and gate maintenance.

[0042] In this embodiment, the gate bottom plate includes a connecting plate 8 and a track 7. The connecting plate 8 is provided with tracks 7 on both sides for water blocking. The two ends of the connecting plate 8 are respectively connected to the power generation box 2 on both sides of the shore. The bottom end of the gate body telescopic box 1 is adapted to abut against the track 7. The preset track 7 is a steel rail protruding upward.

[0043] In this embodiment, the connecting plate 8 is a stepped connecting plate arranged transversely along the river, and the connecting plate 8 is adapted to the bottom end of the gate body telescopic box 1 to ensure that good anti-slip force is formed after the gate body sinks.

[0044] In this embodiment, the gate body telescopic box 1 is composed of a plurality of telescopic shells which are mutually sleeved, and a limiting device is provided on each of the telescopic shells. Specifically, the limiting device used in this embodiment is a stop block or a mechanical locking device to prevent the telescopic shell from falling off during telescoping. The bottom ends of the two power generation boxes 2 are connected by a gate bottom plate; Figure 8 As shown, partitions are arranged between the telescopic shells in the telescopic box 1 of the gate body, and holes are arranged on the partitions. The output end of the driving device is fixed on the docking device 5 through the hole, and the size of the hole can be gradually reduced from the shore to the center of the river channel. The output end of the driving device is composed of a plurality of driving connecting tubes of different sizes that are mutually sleeved. The output end of the driving device is adapted to the hole, so that the driving device is more stable. A gravity adjustment component is arranged inside the telescopic shell. Panel beams 4 and ribs are arranged on both sides of the telescopic shell for water blocking. An inner concave groove adapted to the track 7 is arranged at the bottom of the telescopic shell. A sealing strip is also arranged between the telescopic shells to improve the sealing of the telescopic box 1 of the gate body.

[0045] In this embodiment, the gravity adjustment component includes a drain pipe, an air filling pipe, an air pump and an air bag 6. The air pump is connected to the air bag 6 through the air filling pipe. A valve is also provided on the air filling pipe. One end of the drain pipe is connected to the air bag 6, and the other end is connected to the outside of the telescopic shell. The air pressure is controlled by the air pump in the air bag 6 to control the filling and drainage inside the air bag 6. The air bag 6 has a very small volume in the uninflated state. When the air bag 6 is inflated, it can fill the entire gate body telescopic box 1, so that the gate body telescopic box floats. The air bag 6 is used as a sealing element when not in use to ensure the sealing of the telescopic shell and the normal filling of the telescopic shell. When the gate body telescopic box 1 needs to be filled with water, the air bag 6 is first in an uninflated or slightly inflated state to provide a channel for the water flow. As the water filling process proceeds, the air bag 6 can be gradually inflated and expanded as needed, thereby adjusting or limiting the flow rate and speed of the water flow. This adjustment capability can accurately control the water level and water filling time according to actual conditions. During the water filling process, the air bag 6 can also play a role in pressure balance. When the water flows through the airbag 6, the inflation state of the airbag 6 can also be used as a feedback signal to help monitor and control the water filling pressure and ensure the stable operation of the gate body telescopic box 1. The air pump is responsible for providing the compressed air required for inflation to the airbag 6. The inflation pipe with good sealing and pressure resistance is a bridge connecting the air pump and the airbag 6, and is responsible for safely and efficiently transmitting the compressed air generated by the air pump to the inside of the airbag 6. The valve plays a role in flow control in the water filling and drainage system. By adjusting the opening size of the valve, the flow rate and speed of the water flow can be accurately controlled. During the water filling process, the valve can adjust the opening according to the preset program or human intervention to achieve accurate control of the water filling speed and amount.

[0046] In this embodiment, the panel beam 4 is in a broken line shape, which can improve the overall strength of the gate body telescopic box.

[0047] In the present embodiment, the driving device is a hydraulic driving device. Specifically, in the present embodiment, a hydraulic press is used as the power source for the extension and splicing of the gate body telescopic box 1. When it is necessary to drive the gate body telescopic box 1 to extend and retract, the hydraulic pump delivers the pressure oil to the hydraulic cylinder to push the piston rod (or plunger) to move, thereby driving the gate body telescopic box 1 to move along a predetermined trajectory. By precisely adjusting the control valve group, the hydraulic device can achieve precise control of the extension and retraction speed and position of the gate body telescopic box 1. During the opening and closing operation of the gate body telescopic box 1, the oil pressure system can flexibly and gradually increase or decrease the oil pressure value according to actual needs, thereby ensuring that the gate body telescopic box 1 can be opened in a smooth and uniform manner, or can be closed and positioned quickly and accurately when needed;

[0048] A hydraulic press is arranged in the telescopic housing to exert thrust on the partition through the hole. The hole of each telescopic box gradually decreases from the shore to the center of the river channel, and then the hydraulic press is retracted to move to the other side to push the gate body telescopic box 1. Since the hydraulic device has the ability to automatically adapt to load changes, it can maintain a stable output pressure, ensuring the continuity and reliability of the movement of the gate body telescopic box 1.

[0049] In this embodiment, the power generation box 2 is provided with a plurality of water passages 10, and the water passages 10 are provided with a turbine set 9. The turbine set 9 for tidal power generation on the shore is used to supply clean and sustainable renewable energy to the gate body telescopic box 1. Figures 12-13 As shown, when a water pressure difference occurs, the turbine unit 9 efficiently captures and utilizes tidal energy for accumulation during the process of water level changes due to tidal fluctuations. Subsequently, the accumulated energy is converted into mechanical energy and further driven by a hydraulic drive device to ensure that the necessary telescopic power is provided for the opening and closing actions of the gate body telescopic box 1 in subsequent operation cycles.

[0050] Working principle:

[0051] When it is necessary to block the tide, the hydraulic drive device is used to start the control of the gate telescopic boxes 1 on both sides to extend toward the river center along the preset track until the two gate telescopic boxes 1 are completely spliced. During the splicing process, the sealing between the gate telescopic boxes 1 is ensured by the precise docking device 5. At the same time, the limit device on the telescopic shell is used to prevent excessive expansion or accidental movement. The main function of the limit device is to ensure that each section of the telescopic box can be accurately in place after the telescopic action is completed, and remain relatively static with the adjacent next section of the telescopic box, thereby preventing excessive expansion or accidental movement.

[0052] After the gate body telescopic box 1 is spliced, the inflation system composed of the air bag 6, air pump, inflation pipe and drainage pipe inside the gate body telescopic box 1 starts to work, filling water into the gate body telescopic box 1, so that the gate body telescopic box 1 sinks as a whole to the gate bottom plate. At the same time, there is a certain gap between the track 7 and the gate body telescopic box 1. The track 7 can ensure that the gate body telescopic box 1 will not deviate along the direction of the water flow, and at the same time, leave appropriate space below to allow water to pass through, thereby effectively reducing the resistance of the water flow to the gate body telescopic box 1, so that it can use its own weight and shape anti-slip force to effectively block the tide.

[0053] The airbag 6 inside the gate body telescopic box 1 can be inflated or evacuated as needed. The uninflated airbag 6 is relatively small and is placed in each telescopic shell. When the gate body telescopic box 1 sinks, the airbag 6 is evacuated to fill the airbag 6 with water to increase its own weight; when it is necessary to restore buoyancy, the airbag 6 is inflated to drain the water inside the airbag 6 and float the gate body telescopic box 1. The upstream and downstream water flows are connected to reduce the water flow resistance, and can shrink with maximum effort; the anti-slip force generated by the self-weight can meet its own stability requirements, which helps to resist the impact and erosion of external water flow, tides and other natural forces, and ensure the long-term stable operation of the tide-blocking system.

[0054] After the tide blocking is over, the water in the gate body telescopic box 1 is emptied through the gravity adjustment component, and the airbag 6 is inflated to restore buoyancy. Subsequently, the gate body telescopic box 1 is retracted and returned to the shore maintenance space under the action of the hydraulic drive device, which is convenient for ships to pass.

[0055] During the tidal blockage, the turbine units 9 deployed on both banks generate electricity and store energy by utilizing the water level difference, so as to provide the required power for the contraction operation of the gate body telescopic box 1 during the next tidal blockage.

[0056] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.

Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
