Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic gates, and in particular to a large-span tide gate with a segmented gate body for transverse opening and closing and an operation method thereof. Background Art

[0002] In order to effectively prevent the invasion of storm surges, building tide gates at river estuaries entering the sea is an effective method. Closing the tide gates before the storm surge arrives can protect people's lives and property.

[0003] The primary function of a tidal gate is to block tides, and most must also meet navigation requirements, requiring a large gate span. Therefore, gate type is a key and challenging aspect of tidal gate design. Currently, existing tidal gate gate types worldwide primarily include vertical gates, curved gates, and triangular gates, with curved gates being more common for those with larger spans. The common feature of existing tidal gates is that they all have steel structures. Consequently, all current tidal gates suffer from heavy gate weights, requiring significant opening and closing forces, resulting in lengthy opening and closing times, high project investment, and high operating costs.

[0004] The water-retaining load of existing sluice gates is transmitted from the gate body to the piers at both ends. For example, the gate bodies of flat vertical gates and horizontal sliding gates are supported by the piers at both ends. For a specific sluice gate, the maximum water-retaining height is fixed. Therefore, for the gate, the larger the gate span, the greater the required rigidity and strength of the gate body, and the greater the required thickness of the gate body. The gates of existing large-span tide gates are very heavy, requiring very large opening and closing capacities. Opening and closing power and opening and closing time are the two controlling factors of extra-large-span tide gates, and both are directly related to the weight of the gate. The larger and heavier the gate, the greater the opening and closing power required, and the longer the opening and closing time. Summary of the Invention

[0005] In view of this, the present invention provides a large-span tide gate with a segmented door body for transverse opening and closing, so as to solve the problems existing in the current large-span tide gates.

[0006] In a first aspect, the present invention provides a large-span tide gate with a segmented door body for transverse opening and closing, comprising:

[0007] The left gate and the right gate are arranged symmetrically along the river channel;

[0008] Each gate is composed of multiple independent door bodies connected end to end and connected in series through simple hinges. The multiple independent door bodies include at least a docking door body at the head end, several standard door bodies in the middle and a door slot door body at the end, and each door body is a rectangular empty box structure;

[0009] The caisson foundation is laid on the riverbed along the river channel, and a plurality of roller pits are provided on the top surface thereof. Both sides of the caisson foundation extend outward to form a cantilever plate;

[0010] Auxiliary fixing hooks are provided on both sides of the bottom of each door section. The auxiliary fixing hooks on each side are locked with the cantilever plate when the door is in place, transmitting the water pressure on the door to the caisson foundation.

[0011] When working, the left gate and the right gate are arranged symmetrically along the transverse direction of the river channel, and the tide blocking and opening and closing are achieved through the coordinated operation of multiple independent gate bodies. In each gate, the docking gate body, the standard gate body and the gate slot gate body are connected in series into a whole through a simple hinge. The connection method of the simple hinge allows each section of the gate body to produce a small displacement in the vertical direction, which can adapt to the uneven settlement of the caisson foundation and the temperature deformation of the gate body itself, while ensuring the integrity in the longitudinal direction. The gate body is a rectangular empty box structure. During the opening and closing process, the bottom of the gate body moves along the caisson foundation and is finally accurately positioned through the roller pit on the top surface of the caisson foundation. After being in place, the auxiliary fixing hooks on the two horizontal sides of the bottom of each door body are clamped and locked with the cantilever plates on the two horizontal sides of the caisson foundation to form a stable constraint, which directly transmits the horizontal water pressure on the door body to the caisson foundation.

[0012] This segmented gate body is connected in series through simply supported hinges, breaking through the span restrictions of traditional gates and adapting to the needs of large-span rivers. The wider the river width, the more prominent the flexibility advantage of the segmented design; the rectangular empty box structure is combined with the simply supported hinge connection, taking into account the lightness of the structure and the overall coordination, and is convenient for production, transportation and on-site assembly; the card-locking of the auxiliary fixing hook and the cantilever plate optimizes the load transfer method, converts the horizontal force into vertical transmission, so that the force on the gate body is only related to the water retaining height and is not restricted by the span, which greatly improves the structural stability; the roller pit on the caisson foundation ensures that the gate body is precisely positioned, and the cooperation of the cantilever plate and the auxiliary fixing hook provides a reliable path for load transfer, which together ensures the efficient tide blocking and safe operation of the tide gate in large-span scenarios.

[0013] In an optional embodiment, the simply supported hinge includes:

[0014] A socket provided at one end of a door section, wherein a socket hole is provided in the socket;

[0015] A socket plug is provided at the other end of the adjacent door body, wherein a socket shaft is provided in the socket plug;

[0016] Wherein, the socket plug is inserted into the socket opening, and the socket shaft penetrates into the socket hole to form a hinged connection.

[0017] The simply supported hinge achieves an articulated connection between adjacent gates through the cooperation of a socket and a plug: the plug at one end of one gate section inserts into the socket at the other end of the adjacent gate section, while the socket shaft in the plug penetrates the socket hole in the socket, forming a relatively rotatable connection structure. This connection method allows adjacent gates to produce an appropriate amount of relative displacement in the vertical direction, thereby adapting to possible uneven settlement of the caisson foundation and deformation of the gate due to temperature changes, ensuring that the various gate sections can still work in a coordinated manner under complex working conditions. In the direction of water flow, the close cooperation between the socket shaft and the socket hole limits the relative movement of the gates, ensuring that the overall gate formed by multiple independent gate sections in series has sufficient integrity to jointly withstand water pressure and stably transfer the load to the caisson foundation through the clamping structure of the auxiliary fixing hook and the cantilever plate. The simply supported hinge design not only meets the flexibility requirements of the gate section layout, but also ensures the stability of the overall force of the gate, providing key support for the tidal gate to adapt to large-span river scenarios.

[0018] In an optional embodiment, the auxiliary fixing hook includes:

[0019] The fixed section is an inverted L-shaped structure, fixed to the outside of the bottom of the door body;

[0020] The movable segment is connected to the end of the fixed segment via a hinge shaft;

[0021] a return spring acting on the movable section;

[0022] Wherein, when the door body is in place, the movable section is deformed into a U-shaped structure under the action of the return spring, clamping the cantilever plate.

[0023] The auxiliary fixing hook achieves a secure connection to the cantilever plate through the coordinated action of the fixed section, movable section and return spring: the fixed section is an inverted L-shaped structure and is fixed to the outside of the bottom of the door body, providing basic support for the entire auxiliary fixing hook; the movable section is connected to the end of the fixed section through a hinge shaft and can rotate around the hinge shaft, and the return spring continuously applies force to the movable section. Figure 5 As shown in the figure, when the door moves, the hinge between the movable section and the fixed section contacts the side wall of the cantilever plate. At this time, the movable section is contacted by the side of the cantilever plate and remains vertical. Figure 4As shown, when the door body moves to the in-place position, that is, the roller falls into the roller pit, the auxiliary fixing hook moves downward as a whole, and the hinge of the movable section is on the lower side of the cantilever plate. The movable section loses the contact with the cantilever plate side and rotates relative to the fixed section. The movable section rotates under the elastic force of the reset spring, and together with the fixed section, it forms a closed U-shaped structure, tightly clamping the cantilever plate of the caisson foundation. This structural design allows the door body to be quickly locked with the cantilever plate after it is in place, converting the horizontal thrust generated by the water pressure into a vertical load and transmitting it to the caisson foundation, thereby enhancing the stability of the door body when blocking water; and when the door body needs to be opened and closed, the external force can overcome the elastic force of the reset spring to expand the movable section, release the clamping of the cantilever plate, and ensure that the door body moves smoothly along the caisson foundation. This deformable design of the auxiliary fixing hook not only ensures reliable force transmission in the tide-blocking state, but also meets the flexible operation requirements during the opening and closing process.

[0024] In an optional embodiment, each door section is provided with:

[0025] The motor compartment is located at the front end of the bottom of the empty box and is equipped with a motor;

[0026] A water collecting chamber is located in the space inside the empty box except for the motor chamber;

[0027] An entry hole is arranged on the top surface of the door body, and the entry hole is connected to the motor compartment.

[0028] The gate of the present invention has its own powered opening and closing technology, which converts the overall opening and closing of the gate into the movement of a single-section gate body, that is, converts the traditional passive opening and closing of the gate into active opening and closing, rewrites the traditional gate starting method, and solves the shortcomings of the existing tide gate opening and closing equipment in the world, such as large capacity and long opening and closing time.

[0029] In an optional embodiment, the output shaft of the motor is connected to a roller, and the roller is located at the bottom of the door body; a drainage pump is provided in the water collection bin, and a water inlet gate is provided on the inner river side wall of the door body.

[0030] The motor's output shaft is connected to the roller at the bottom of the gate, providing power for the roller to move, driving the single-section gate along the track of the caisson foundation, and thus driving the entire gate to open and close horizontally. The independent drives of each section of the gate work together to improve the gate's opening and closing efficiency. The drainage pump in the water collection chamber can drain the accumulated water, reducing the weight of the gate to reduce the opening and closing resistance and facilitate its movement. When the water inlet gate on the river side of the gate body is opened, water can be filled into the water collection chamber, increasing the deadweight of the gate. Combined with the locking of the auxiliary fixing hook and the cantilever plate, the stability of the gate when blocking tides is enhanced, ensuring that the gate is firmly in place under the action of water pressure. This design enables the gate to coordinate power drive and weight adjustment, which not only meets the flexibility of the opening and closing process, but also ensures the reliability of the tide-blocking state, adapting to the operational requirements of large-span tide gates.

[0031] In an optional embodiment, the wheelbase of each door section gradually decreases toward the closing direction of the door.

[0032] In an optional embodiment, the docking end of one side of the docking door body is provided with an elastic convex plug, and the docking end of the other side of the docking door body is provided with a concave groove;

[0033] When the left gate and the right gate are docked in the middle of the river channel, the plug of the docking gate body of one gate is inserted into the concave groove of the docking gate body of the other gate to form a simply supported hinge.

[0034] The docking ends of the gate bodies are equipped with elastic convex plugs and concave grooves. When the left and right gates are docked in the middle of the river channel, the elastic convex plug of one gate's docking body precisely inserts into the concave groove of the other gate's docking body, and the two engage with each other to form a simply supported hinge. On the one hand, this docking structure uses the combination of the elastic convex surface and the concave groove to achieve a tight connection between the two gates, ensuring the integrity during tide blocking and the sealing of the door panels on both sides, which can jointly resist water pressure. On the other hand, the simply supported hinge formed allows the two gates to produce slight relative displacement in the vertical direction, which can adapt to possible uneven settlement or temperature deformation of the caisson foundations on both sides and prevent damage at the docking point due to stress concentration.

[0035] In an optional embodiment, the method further includes:

[0036] Gate warehouses located behind embankments on both sides of the river;

[0037] A control gate connected to the door garage, wherein the bottom plate of the control gate is a reversible movable bottom plate;

[0038] After the movable bottom plate is flipped down, its top surface is flush with the top surface of the caisson foundation, forming a continuous roller track surface;

[0039] After the movable bottom plate is flipped and vertically erected, the control gate can be closed.

[0040] The gatehouses behind the dikes on both sides of the river are used to store the left and right gates in the open state, while the control gates connected to the gatehouses serve to separate the gatehouses from the river. The bottom plate of the control gate is designed as a reversible movable bottom plate. When the tide gate needs to be opened and closed, the movable bottom plate is flipped down and its top surface remains flush with the top surface of the caisson foundation, forming a continuous roller track surface. This design ensures that the rollers at the bottom can move smoothly along the continuous track when the gate moves from the gatehouse to the center of the river (closing process) or from the center of the river to the gatehouse (opening process), avoiding obstruction or deviation of the gate operation due to track interruption. At the same time, the reversible nature of the movable bottom plate allows the gate to be adjusted by flipping after it is stored in the gatehouse, and cooperates with the control gate to achieve the closure of the gatehouse, creating a dry environment for gate inspection and maintenance. It takes into account the smoothness of gate operation and the convenience of subsequent maintenance, and is adapted to the overall operational requirements of large-span tide gates.

[0041] In a second aspect, the present invention further provides a method for operating the sectional door body to transversely open and close a large-span tide gate, comprising a step of closing the tide gate and a step of opening the tide gate, wherein the step of closing the tide gate comprises:

[0042] Open the control gate, flip and lower the movable bottom plate, then start the motor in each section of the gate body to drive the entire tide gate to move horizontally from the gate reservoir to the designed tide blocking position in the river channel;

[0043] The rollers at the bottom of each door body fall into the roller pits corresponding to the top surface of the caisson foundation, and the door body bottom plate falls on the top surface of the caisson foundation;

[0044] The movable section of the auxiliary fixing hook is deformed and locked to the cantilever plate under the action of a return spring in the auxiliary fixing hook;

[0045] Open the water inlet gate on the river side wall of each gate body and fill water into the empty box of the gate body to the designed water level.

[0046] In an optional embodiment, the step of opening the tide gate includes:

[0047] Start the drainage pump in each door body water collection tank to drain the water in the empty tank until the weight of the door body is slightly greater than the buoyancy;

[0048] Release the lock of the auxiliary fixing hook on the cantilever plate;

[0049] Start the motors in each door section to synchronously drive the entire tide gate to move horizontally back to the gate warehouse;

[0050] Flip up the movable bottom plate, close the control gate, and the door garage is in a protected state. The door body can be maintained or repaired at any time. BRIEF DESCRIPTION OF THE DRAWINGS

[0079] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0080] In order to effectively prevent the invasion of storm surges, building tide gates at river estuaries entering the sea is an effective method. Closing the tide gates before the storm surge arrives can protect people's lives and property.

[0081] The primary function of a tidal gate is to block tides, and most must meet navigation requirements. Intermediate piers are not permitted, and gates generally require a large span. Therefore, gate type is a key and challenging aspect of tidal gate design. Currently, existing tidal gate gate types worldwide primarily include vertical gates, curved gates, and triangular gates, with curved gates being more common for those with larger spans. The common feature of existing tidal gates is that they all have steel structures. Consequently, all tidal gates are generally heavy, require significant opening and closing forces, and require long opening and closing times, resulting in significant project investment and high operating costs.

[0082] The technical deficiencies of the above-mentioned tide gates are mainly due to the fact that the water-retaining load of existing sluice gates is transmitted from the gate body to the piers at both ends. For example, the gate bodies of flat vertical doors and horizontal sliding doors are supported by the piers at both ends. For a specific sluice gate, the maximum water-retaining height is fixed. Therefore, as far as the gate is concerned, the larger the span of the gate hole, the greater the rigidity and strength required for the gate body, and the greater the thickness required for the gate body. The gates of existing large-span tide gates are very heavy, and the required opening and closing capacity is very large. The opening and closing power and opening and closing time are the two controlling factors of large-span tide gates, and both are directly related to the weight of the gate. The larger and heavier the gate, the greater the opening and closing power required, and the longer the opening and closing time.

[0083] In view of this, the present embodiment provides a large-span tide gate with a segmented door body that can be opened and closed laterally, so as to solve the problem of the large-span tide gate with a segmented door body that can be opened and closed laterally.

[0084] The following combination Figures 1 to 12 , describing embodiments of the present invention.

[0085] According to an embodiment of the present invention, on the one hand, a sectional gate body is provided for horizontally opening and closing a large-span tide gate, comprising a left gate and a right gate, a caisson foundation 4, and an auxiliary fixing hook 5. The left gate and the right gate are arranged symmetrically along the river channel, and each gate is composed of multiple independent gate bodies connected in series by simply supported hinges. The multiple independent gate bodies at least include a docking gate body 1 at the head end, a standard gate body 2 in the middle of several sections, and a gate slot gate body 3 at the end, and each gate body is a rectangular hollow box structure; the caisson foundation 4 is laid on the riverbed along the river channel, and a plurality of roller pits 401 are provided on its top surface. Both sides of the caisson foundation 4 extend outward to form a cantilever plate 402; auxiliary fixing hooks 5 are provided on both sides of the bottom of each gate body section. When the gate body is in place, the auxiliary fixing hooks 5 on each side are locked with the cantilever plate 402, converting the water pressure on the gate body into a vertical load and transmitting it to the caisson foundation 4.

[0086] When working, the left gate and the right gate are arranged symmetrically along the river channel, and the tide blocking and opening and closing are achieved through the coordinated operation of multiple independent gate bodies. In each gate, the docking gate body 1, the standard gate body 2 and the gate slot gate body 3 are connected in series as a whole through a simple hinge. The connection method of the simple hinge allows each section of the gate body to produce a small displacement in the vertical direction, which can adapt to the uneven settlement of the caisson foundation 4 and the temperature deformation of the gate body itself, while ensuring the integrity in the direction of water flow. The gate body is a rectangular empty box structure. During the opening and closing process, the bottom of the gate body moves along the caisson foundation 4, and is finally accurately positioned in place through the roller pit 401 on the top surface of the caisson foundation 4. After being in place, the auxiliary fixing hooks 5 on the horizontal sides of the bottom of each door body are locked with the cantilever plates 402 on the horizontal sides of the caisson foundation 4 to form a stable constraint, which converts the horizontal water pressure on the door body into a vertical load and directly transmits it to the caisson foundation 4.

[0087] In this embodiment, the segmented gate bodies are connected end to end and connected in series through simple hinges, which breaks through the span restrictions of traditional tide gates and can adapt to the needs of large-span rivers. The wider the river width, the more prominent the flexibility advantage of the segmented design; the rectangular empty box structure is combined with the simple hinge connection, taking into account the lightness of the structure and the overall coordination, which is convenient for production, transportation and on-site assembly; the auxiliary fixing hook 5 is locked by the cantilever plate 402, which optimizes the load transfer method and converts the horizontal force into vertical transmission, so that the force on the gate body is only related to the water retaining height and is not restricted by the span, thereby greatly improving the structural stability; the roller pit 401 on the caisson foundation 4 ensures that the gate body is precisely positioned, and the cooperation of the cantilever plate 402 and the auxiliary fixing hook 5 provides a reliable path for load transfer, which together ensures the efficient tide blocking and safe operation of the tide gate in large-span scenarios.

[0088] Furthermore, expansion joints and rubber waterstops are provided between individual gate sections. Each gate section is a flat, standardized, prefabricated steel gate. The gates are factory-fabricated in sections and assembled on-site in a 12-meter door hangar. Once assembled and debugged, they are ready for operation.

[0089] In one embodiment, the simply supported hinge comprises a socket provided at one end of a single-section door body, wherein the socket is provided with a socket hole 6, and a socket plug provided at the other end of another adjacent single-section door body, wherein the socket plug is provided with a socket shaft 7;

[0090] The socket of the front door body is inserted into the socket of the rear door body, and the socket shaft 7 is inserted into the socket hole 6 to form a hinged connection. Figure 2 、 Figure 6 and Figure 8 As shown, the docking door body 1 is provided with a socket hole 6 at only one end, the door slot door body 3 is provided with a socket plug at only one end, and the standard door body 2 is provided with a socket hole 6 and a socket plug at both ends respectively.

[0091] In this embodiment, the simply supported hinge achieves a hinged connection between adjacent gate bodies through the cooperation of a socket and a socket plug: the socket plug at one end of a gate body is inserted into the socket at the other end of the adjacent gate body, and the socket shaft 7 in the socket plug is inserted into the socket hole 6 in the socket, forming a relatively rotatable connection structure. This connection method allows adjacent gate bodies to produce an appropriate amount of relative displacement in the vertical direction, thereby adapting to the possible uneven settlement of the caisson foundation 4 and the deformation of the gate body due to temperature changes, ensuring that the various gate bodies can still work in a coordinated manner under complex working conditions. In the direction of water flow, the close cooperation between the socket shaft 7 and the socket hole 6 limits the relative movement of the gate bodies, ensuring that the integrated tide gate formed by the multiple independent gate bodies connected in series has sufficient integrity, can jointly withstand water pressure, and stably transfer the load to the caisson foundation 4 through the clamping structure of the auxiliary fixing hook 5 and the cantilever plate 402. The design of the simply supported hinge not only meets the flexibility requirements of the gate body segment layout, but also ensures the stability of the overall force of the tide gate, providing key support for the tide gate to adapt to large-span river scenarios.

[0092] In one embodiment, Figure 4 and Figure 5 As shown, the auxiliary fixing hook 5 includes a fixed section 51, a movable section 52 and a return spring. The fixed section 51 is an inverted L-shaped structure, fixed to the outer side of the bottom of the door body; the movable section 52 is connected to the end of the fixed section 51 through a hinge shaft, and the return spring acts on the movable section 52; wherein, when the door body is in place, the movable section 52 is deformed into a U-shaped structure under the action of the return spring, clamping the cantilever plate 402.

[0093] In this embodiment, the auxiliary fixing hook 5 achieves a secure connection to the cantilever plate 402 through the coordinated action of the fixed section 51, the movable section 52 and the return spring: the fixed section 51 is an inverted L-shaped structure and is fixed to the outer side of the bottom of the door body, providing basic support for the entire auxiliary fixing hook 5; the movable section 52 is connected to the end of the fixed section 51 through a hinge shaft and can rotate around the hinge shaft, and the return spring continuously applies force to the movable section 52. Figure 5 As shown, when the door moves, the hinge between the movable section 52 and the fixed section 51 abuts against the side wall of the cantilever plate 402. At this time, the movable section 52 is abutted against the side of the cantilever plate 402 and remains vertical. Figure 4As shown, when the door body moves to the in-place position, that is, the roller 9 falls into the roller pit 401, the auxiliary fixing hook 5 moves downward as a whole, the hinge of the movable section 52 is on the lower side of the cantilever plate 402, the movable section 52 loses the contact with the cantilever plate 402 side and rotates relative to the fixed section 51, and the movable section 52 rotates under the elastic force of the return spring, forming a closed U-shaped structure together with the fixed section 51, tightly clamping the cantilever plate 402 of the caisson foundation 4. This structural design allows the door body to quickly lock with the cantilever plate 402 after it is in place, converting the horizontal thrust generated by the water pressure into a vertical load and transmitting it to the caisson foundation 4, thereby enhancing the stability of the door body when blocking water; and when the door body needs to be opened and closed, the external force can overcome the elastic force of the return spring to expand the movable section 52, release the clamping of the cantilever plate 402, and ensure that the door body moves smoothly along the caisson foundation 4. This deformable design of the auxiliary fixing hook 5 not only ensures reliable force transmission in the moisture-proof state, but also meets the flexible operation requirements during the opening and closing process.

[0094] During the tidal gate opening process, auxiliary fixing hooks 5 are located on either side of the gate. The auxiliary fixing hooks 5, the gate, and the auxiliary fixing hooks 5 form a large inverted U-shaped structure that is clamped on both sides of the caisson foundation 4, primarily serving as a guide. During the opening and closing process, the weight of the gate and the weight of the empty caisson water maintain the gate's stability.

[0095] In one embodiment, Figure 2 、 Figure 3 、 Figure 6 and Figure 8 As shown, each door section is equipped with a motor compartment 81, a water collection compartment 83, and a manhole 84. The motor compartment 81 is located at the front end of the bottom of the empty box and contains a motor 82. The water collection compartment 83 is located in the space inside the empty box, excluding the motor compartment 81. The manhole 84 is located on the top surface of the door and is connected to the motor compartment 81. In the docking door 1 and the standard door 2, each door section is equipped with a motor 82 to drive the door section. Only the door slot 3 of the door garage 12 is equipped with two motors 82, namely, one at each end of the door.

[0096] The internal structural design of each door section not only meets the power drive requirements, but also takes into account the convenience of operation and maintenance: the motor compartment 81 is located at the front end of the bottom of the empty box, and the built-in motor 82 provides power for the horizontal opening and closing of the door body, ensuring that the single door section can be driven independently and move in coordination with other door bodies to achieve the overall opening and closing of the tide gate; the water collection compartment 83 occupies the space in the empty box except for the motor compartment 81. It can increase the weight of the door body by filling it with water to improve its stability when blocking the tide, or reduce its weight by draining water to facilitate opening and closing, and flexibly adjust the stress state of the door body; the manhole 84 on the top surface of the door body is connected to the motor compartment 81, providing an access channel for staff to facilitate the inspection, maintenance and debugging of equipment such as the motor 82. This reasonable division of internal space enables each door section to have independent driving capabilities while taking into account the structural stability adjustment and equipment maintenance needs, ensuring that each door section plays an efficient and reliable role in the large-span tide gate system.

[0097] The tide gate of this embodiment has its own powered opening and closing technology, which converts the overall opening and closing of the tide gate into the movement of a single-section gate body, that is, converts the traditional passive opening and closing of the tide gate into active opening and closing, rewrites the traditional tide gate starting method, and solves the shortcomings of the existing tide gate opening and closing equipment in the world, such as large capacity and long opening and closing time.

[0098] Further, if Figures 3 to 5 、 Figure 8 As shown, the output shaft of the motor 82 is connected to the roller 9, and the roller 9 is located at the bottom of the door body; a drainage pump 85 is provided in the water collection bin 83, and a water inlet gate 86 is provided on the inner river side wall of the door body.

[0099] The output shaft of the motor 82 is connected to the roller 9 at the bottom of the gate body, providing power for the rotation of the roller 9, driving the single-section gate body to move along the track of the caisson foundation 4, and then driving the entire tide gate to open and close horizontally. The independent drive of each section of the gate body can cooperate with each other to improve the opening and closing efficiency of the tide gate. The drainage pump 85 in the water collection bin 83 can discharge the accumulated water in the bin, reduce the weight of the gate body to reduce the opening and closing resistance, and facilitate the movement of the gate body; and when the water inlet gate 86 on the river side wall of the gate body is opened, water can be filled into the water collection bin 83 to increase the deadweight of the gate body, and cooperate with the auxiliary fixing hook 5 to lock the cantilever plate 402 to enhance the stability of the gate body when blocking the tide, and ensure that the gate body is firmly in place under the action of water pressure. This design enables the gate body to meet the flexibility of the opening and closing process and ensure the reliability of the tide-blocking state through the coordination of power drive and weight adjustment, and adapt to the operation requirements of large-span tide gates. An inlet hole 87 is centrally located on the inland river side of the door. Its center elevation is the designed inland river water level. An inlet gate 86 is installed within the door to control the opening and closing of the hole. Prefabricated counterweights 88 are provided with at least three hooks and loops for securing to the bottom surface. The number of prefabricated counterweights 88 is determined by calculation and evenly distributed across the bottom of the door's hollow box.

[0100] Furthermore, the wheelbase of each door section gradually decreases in the direction of door closing. The wheelbase of each door section gradually decreases in the direction of door closing, and this design is compatible with the arrangement of the roller pit 401 on the top surface of the caisson foundation 4. Since the door body opens and closes horizontally along the river channel, it needs to move toward the center of the river channel and finally dock when closing. The wheelbase gradually decreases in the closing direction, which can ensure that the roller 9 at the bottom of each door section can accurately fall into the corresponding roller pit 401, avoiding track interference of the rollers 9 of adjacent door bodies during movement. Specifically, the rollers 9 are symmetrically installed at the head of each single-section door body. The two rollers 9 installed at the bottom of the docking door body 1 have the largest wheelbase. The docking door body 1 and the standard door body 2 are both installed with two rollers 9, and only the gate slot door body 3 is installed with three rollers 9. The rollers 9 are arranged corresponding to the docking pits.

[0101] In one embodiment, the docking end of the docking gate body 1 is provided with an elastic convex plug 10 or a concave groove 11; wherein, when the left gate and the right gate are docked in the middle of the river channel, the plug of the docking gate body 1 of one gate is inserted into the concave groove 11 of the docking gate body 1 of the other gate, and a simply supported hinge is formed.

[0102] In this embodiment, Figure 7 As shown, the docking ends of the docking gate body 1 are respectively provided with an elastic convex plug 10 and a concave groove 11. When the left gate and the right gate are docked in the middle of the river channel, the elastic convex plug 10 of the docking gate body 1 of one gate will be accurately inserted into the concave groove 11 of the docking gate body 1 of the other gate, and the two will engage with each other to form a simply supported hinge. On the one hand, this docking structure uses the cooperation of the elastic convex surface and the concave groove 11 to achieve a tight connection between the two gates, ensuring the integrity and sealing when blocking the tide, and can jointly resist water pressure; on the other hand, the simply supported hinge formed allows the two gates to produce a slight relative displacement in the vertical direction, which can adapt to the uneven settlement or temperature deformation of the caisson foundations 4 on both sides, and avoid damage to the docking due to stress concentration.

[0103] In one embodiment, the segmented gate body with a transversely opened and closed large-span tide gate further includes a gatehouse 12 located behind the embankments on both sides of the river channel and a control gate 13 connected to the gatehouse 12, wherein the bottom plate of the control gate 13 is a flippable movable bottom plate 14; wherein, after the movable bottom plate 14 is flipped and lowered, its top surface is flush with the top surface of the caisson foundation 4, forming a continuous roller 9 track surface.

[0104] In this embodiment, the gatehouse 12 behind the dikes on both sides of the river is used to store the left and right gates in the open state, and the control gate 13 connected to the gatehouse 12 plays the role of separating the gatehouse 12 from the river. The bottom plate of the control gate 13 is designed as a reversible movable bottom plate 14. When the tide gate needs to be opened and closed, Figure 12As shown, the movable bottom plate 14 is flipped down and its top surface is kept flush with the top surface of the caisson foundation 4, forming a continuous track surface for the roller 9. This design ensures that when the gate moves from the gatehouse 12 to the center of the river (closing process) or from the center of the river to the gatehouse 12 (opening process), the roller 9 at the bottom can move smoothly along the continuous track, avoiding obstruction or deviation of the gate movement due to track interruption. At the same time, the flippable feature of the movable bottom plate 14 allows the tide gate to be adjusted to a vertical state (such as Figure 12 (as shown by the middle dotted line), closing the control gate 13 realizes the closure of the gate library 12, creating a dry environment for the inspection and maintenance of the gate body, taking into account the smoothness of the operation of the tide gate and the convenience of subsequent maintenance, and adapting to the overall operation requirements of the large-span tide gate.

[0105] Specifically, once the tide gate is opened and fully retracted into the gate compartment 12, the movable floor 14 is flipped back to its closed position. At this point, the movable floor 14 no longer serves as an extension of the track for the roller 9, but instead functions as the floor structure for the control gate 13, blocking the flow between the gate compartment 12 and the river. Closing the control gate 13 seals the gate compartment 12 into a closed space. Subsequently, a drainage pump within the gate compartment 12 drains the accumulated water, creating a dry environment within the gate compartment 12.

[0106] On the one hand, this closed design utilizes the water-blocking function of the control gate 13 to protect the gate base 12, preventing external tides or river water from entering the gate base 12 and affecting the equipment; on the other hand, it provides stable dry-land working conditions for the inspection and maintenance of the door body. Workers can enter the interior through the manhole 84 on the top surface of the door body to inspect and repair equipment such as the motor 82 and the drainage pump 85 to ensure that the door body is always in good operating condition.

[0107] According to an embodiment of the present invention, on the other hand, a method for operating a sectional door body to transversely open and close a large-span tide gate is provided, comprising a step of closing the tide gate and a step of opening the tide gate, wherein the step of closing the tide gate comprises:

[0108] Open the control gate 13, flip down the movable bottom plate 14, and then start the motor 82 in each section of the gate body to drive the entire tide gate to move horizontally from the gate library 12 to the designed tide blocking position of the river channel;

[0109] The rollers 9 at the bottom of each door body fall into the roller pits 401 corresponding to the top surface of the caisson foundation 4, and the door body bottom plate falls on the top surface of the caisson foundation 4;

[0110] The movable section 52 of the auxiliary fixing hook 5 is deformed and locked to the cantilever plate 402 under the action of the return spring in the auxiliary fixing hook 5;

[0111] Open the water inlet gate 86 on the river side wall of each gate body and fill water into the gate body empty box to the designed water level.

[0112] When closing the tide-blocking gate, first start the motor 82 in each section of the gate body to drive the entire tide-blocking gate from the gate library 12 along the continuous roller 9 track formed by the top surface of the caisson foundation 4 and the movable bottom plate 14 of the control gate 13 to run horizontally until it reaches the designed tide-blocking position of the river channel; after running into position, the roller 9 at the bottom of each gate body falls accurately into the roller pit 401 corresponding to the top surface of the caisson foundation 4, and the gate body bottom plate then falls on the top surface of the caisson foundation 4 to achieve the initial positioning of the gate body; at this time, the movable section 52 of the auxiliary fixing hook 5 is deformed under the action of the reset spring, and together with the fixed section 51, it forms a U-shaped structure, tightly clamping the cantilever plate 402 of the caisson foundation 4 to complete the fixed locking of the gate body; finally, open the water inlet gate 86 on the river side wall of each gate body, fill the water collection bin 83 of the empty box of the gate body with water to the designed water level, increase the deadweight of the gate body to improve the stability during tide blocking, ensure that the gate can withstand water pressure stably, and complete the entire closing process.

[0113] In one embodiment, the step of opening the tide gate includes:

[0114] Start the drainage pump 85 in each door water collection bin 83 to drain the water in the empty box until the weight of the door is slightly greater than the buoyancy;

[0115] Release the auxiliary fixing hook 5 from locking the cantilever plate 402;

[0116] The motor 82 in each door body is started to synchronously drive the entire tide gate to move horizontally back to the door library 12.

[0117] When opening the tide gate, it is necessary to first ensure that the water levels inside and outside the tide gate are basically the same, then close the water inlet gate 86 on the river side wall of each gate body, start the drainage pump 85 in the water collection tank 83, and drain the excess water in the empty box so that the gravity of the gate body is slightly greater than the buoyancy; then, start the motor 82 in each section of the gate body to drive the roller 9 to climb out of the roller pit 401 of the caisson foundation 4 along the track, and the movable section 52 of the auxiliary fixing hook 5 overcomes the elastic force of the return spring to unfold, release the lock on the cantilever plate 402, and the entire gate moves horizontally to the gate base 12; after the gate has completely entered the gate base 12, flip and erect the movable bottom plate 14, and then close the control gate 13 to achieve the closure of the gate base 12 and complete the opening process. The gate base 12 is in a protective state, and the gate body can be maintained or repaired at any time.

[0118] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention. Such modifications and variations are all within the scope defined by the appended claims.
