[0002] With the continuous expansion of the scale of water conservancy and hydropower projects in my country, the layout of key projects is increasingly trending towards larger openings and longer spans. Correspondingly, the span of gates is also increasing, resulting in a surge in the overall steel consumption and weight of the gates. However, the opening and closing of traditional gates mainly relies on electric power, which greatly increases energy consumption and leads to very high overall operation and maintenance costs for the gates.

[0003] Therefore, there is an urgent need to develop a new type of gate with low operation and maintenance costs. Summary of the Invention

[0009] A floating column, connected to the floating platform, is used to cause the floating platform to rise and fall; when the floating column is filled with water, it causes the floating platform to sink.

[0011] A floating suspended gate, one end of which is hinged to the floating platform, and the other end which can float or sink relative to the floating platform; and the floating suspended gate and the floating column are spaced apart.

[0014] In some embodiments, the floating gate further includes a positioning hole disposed on the bottom sill, and the first column engages with the positioning hole when it sinks.

[0015] In some embodiments, the floating suspended door includes a door leaf structure with a second regulating water tank, a hinge structure, and a second filling and draining device. The hinge structure is connected to the floating platform, and the door leaf structure is hinged to the hinge structure. One end of the door leaf structure away from the hinge structure is rotatable relative to the hinge structure. The second filling and draining device is disposed on the floating platform and is used to fill and drain the second regulating water tank.

[0016] In some embodiments, the second filling and draining device includes a second air compressor, a second inlet trash rack, and a second electric gate valve. The second air compressor is disposed on the floating platform, and the second inlet trash rack and the second electric gate valve are disposed on the gate leaf structure, with the second inlet trash rack and the second electric gate valve being disposed correspondingly.

[0017] In some embodiments, the floating platform has a door vault facing the sill, one end of the hinge structure is connected to the inner wall of the door vault, and the door leaf structure is embedded in the door vault when it is not in operation;

[0018] The inner wall of the door frame away from the hinge structure is provided with a locking device, which is snapped into the other end of the door leaf structure.

[0019] In some embodiments, the bottom sill is provided with a water-blocking protrusion, and the other end of the door leaf structure abuts against the water-blocking protrusion when it sinks.

[0020] In some embodiments, the floating gate includes a spherical bearing, and the floating platform is rotatably connected to the support column via the spherical bearing; the floating platform is provided with an equipment compartment, and the drive device is disposed in the equipment compartment.

This floating gate significantly reduces the energy consumption of electric drive during the sinking process, effectively solving the problem of high overall operation and maintenance costs for gates.

[0048] In the embodiments of this application, the words "exemplary" or "for example" are used to indicate that they are examples, illustrations, or descriptions. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design; rather, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0049] This application provides a floating gate. For example... Figure 1-5 As shown, in some embodiments, the floating gate may include a gate bottom plate (not shown), a support column 2 connected to the gate bottom plate, and a gate body 001 connected to the support column 2. The gate body 001 includes a floating platform 1, a floating column 3, a drive device 4, and a floating suspended gate 5. The floating platform 1 is movably connected to the support column 2 and can float and sink relative to the support column 2. The floating column 3 is connected to the floating platform 1 and is used to drive the floating platform 1 to float and sink. When the floating column 3 is filled with water, it drives the floating platform 1 to sink. The drive device 4 is disposed on the floating platform 1 and is used to drive the floating platform 1 to rotate. One end of the floating suspended gate 5 is hinged to the floating platform 1, and the other end of the floating suspended gate 5 can float and sink relative to the floating platform 1. The floating suspended gate 5 and the floating column 3 are spaced apart. When the floating suspended gate 5 is filled with water, the other end of the floating suspended gate 5 sinks and abuts against the bottom sill 7 to block the water flow.

[0050] Specifically, such as Figure 1 and Figure 2 As shown, two gate piers 100 are set in the lock chamber section, and the gate body 001 is set between the two gate piers 100. When it is necessary to close the orifice, the gate body 001 can be closed. At this time, the two ends of the gate body 001 abut against the gate piers 100, which can block the water flow. When the river channel needs to be navigable, the gate body 001 can be opened. At this time, the gate body 001 is parallel to the water flow direction of the river channel, allowing ships to pass. In the embodiments of this application, the single floating gate can be single or multiple. When the net distance between the two gate piers 100 is large, multiple floating gates can be added to jointly block the orifice with a large span.

[0051] like Figures 3 to 5As shown, the lower end of the support column 2 can be fixed to the embedded part of the gate bottom plate by bolts or welding, and the gate body 001 can be rotatably connected to the upper end of the support column 2 by a connector. The drive device 4 can be detachably connected to the upper surface of the gate body 001 by bolts. The drive device 4 can drive the gate body 001 to rotate relative to the support column 2, which facilitates the opening and closing of the gate body 001.

[0052] For example, such as Figure 1 and Figure 2 As shown, when used for openings with ultra-large spans, multiple gate bodies 001 can be set, and correspondingly, multiple support columns 2 can be set for the multiple gate bodies 001.

[0053] like Figure 3 As shown, the floating platform 1 can be rotatably connected to the upper end of the support column 2 via a connector, and the floating platform 1 can be driven to rotate relative to the support column 2 via a drive device 4. The floating column 3 can be a box structure, and the floating column 3 can be connected to the lower end face of the floating platform 1 by welding. When the floating column 3 is filled with water and sinks, it can drive the floating platform 1 to sink. When the floating column 3 is dewatered and floats, it can drive the floating platform 1 to float.

[0054] For example, the floating suspended door 5 can be a box-shaped sealed structure. One end of the floating suspended door 5 can be movably connected to the lower end face of the floating platform 1 through a hinge. When the floating suspended door 5 is filled with water, its other end can float or sink relative to the floating platform 1. For example, when the floating suspended door 5 is filled with water, its other end can sink and abut against the bottom sill 7, thereby blocking the water flow.

[0055] The floating gate provided in this application embodiment is achieved by movably connecting a floating platform 1 to a support column 2, wherein the floating platform 1 can rotate around the support column 2 and can float and sink relative to the support column 2, and a floating column 3 is connected to the floating platform 1; at the same time, one end of a floating suspended gate 5 is movably connected to the floating platform 1, and the other end of the floating suspended gate 5 can float and sink relative to the floating platform 1, and the floating suspended gate 5 and the floating column 3 are spaced apart.

[0056] For example, sealing elements are provided between each floating suspended door 5 and between the floating suspended door 5 and the support column 2 or floating column 3, which can further improve the sealing performance in the water-blocking state.

[0057] Therefore, when it is necessary to block the water flow at the orifice, water can be pumped into the floating column 3, causing the floating platform 1 to sink, and water can be pumped into the floating suspension gate 5, causing the other end of the floating suspension gate 5 to sink and abut against the bottom sill 7, thereby blocking the water flow. This floating gate greatly reduces the energy consumption of electric drive during the sinking and water flow blocking process, and can effectively solve the problem of high overall operation and maintenance costs of the gate.

[0058] Since the rotation and buoyancy of the floating platform 1 and the buoyancy of the floating gate 5 both utilize hydraulic characteristics, the capacity of the opening and closing equipment can be effectively reduced. When the floating gate is not in operation, both the floating platform 1 and the floating gate 5 lie flat above the water surface, making inspection and maintenance convenient. Furthermore, the floating gate 5 and the floating column 3 are arranged at intervals, and multiple floating gates can effectively block ultra-large span river channels. Moreover, the opening and closing of the floating gate both utilize hydraulic characteristics, and multiple floating gates can block ultra-large span river channels, which can effectively adapt to the current development trend of water conservancy projects and solve the problems of large orifice, large span gate, gate hoist selection, and structural design difficulties.

[0059] like Figure 5 As shown, in some embodiments, the floating column 3 may include a first column 31 with a first regulating water tank and a first filling and draining device 32. The first column 31 is connected to the lower part of the floating platform 1 and extends towards the bottom sill 7. The first filling and draining device 32 is disposed on the floating platform 1 and is used to fill and drain the first regulating water tank. The first column 31 can be connected to the lower end face of the floating platform 1 by welding. The first filling and draining device 32 can be detachably installed inside the floating platform 1 by bolts to save the volume space of the floating platform 1.

[0060] Based on this structure, the first regulating water tank can be filled and drained using the first filling and draining device 32. When water is filled into the first regulating water tank, the first column 31 sinks and causes the floating platform 1 to sink; when water is drained from the first regulating water tank, the first column 31 floats and causes the floating platform 1 to float. For example, when it is necessary to close the orifice to block the water flow, water can be filled into the first regulating water tank to sink the first column 31, thereby causing the floating platform 1 to sink.

[0061] For example, such as Figure 5As shown, the first filling and draining device 32 may include a first air compressor 321, a first inlet trash rack 322, and a first electric gate valve 323. The first air compressor 321 is mounted on the floating platform 1, and the first inlet trash rack 322 and the first electric gate valve 323 are mounted on the first column 31, with the first inlet trash rack 322 and the first electric gate valve 323 being correspondingly arranged. The first air compressor 321 can be bolted to the inside of the floating platform 1 to save space. The first inlet trash rack 322 can be located at the water inlet of the first column 31 to prevent dirt in the water from entering the column and affecting the normal operation of the equipment. Based on this structure, when the first electric gate valve 323 is opened and the first air compressor 321 is closed, external water can flow into the first regulating water tank of the first column 31 by gravity, thereby causing the first column 31 to sink; when the first electric gate valve 323 is opened and the first air compressor 321 is turned on, the water in the first regulating water tank of the first column 31 can be forcibly discharged to the outside, thereby causing the first column 31 to float.

[0062] like Figure 1 and Figure 5 As shown, in some embodiments, the floating gate also includes a positioning hole 8 disposed on the bottom sill 7, which engages with the first column 31 when it sinks. For example, the size of the positioning hole 8 can be slightly larger than the size of the floating column 3. Specifically, the size of the positioning hole 8 can be slightly larger than the size of the first column 31. Based on this structure, it is beneficial to the sinking positioning and limiting function of the first column 31, and can also further improve the overall stability of the floating gate structure.

[0063] like Figure 3 and Figure 5 As shown, in some embodiments, the floating suspended door 5 may include a door leaf structure 51 with a second regulating water tank, a hinge structure 52, and a second filling and draining device 53. The hinge structure 52 is connected to the floating platform 1, and the door leaf structure 51 is hinged to the hinge structure 52. One end of the door leaf structure 51 away from the hinge structure 52 can rotate relative to the hinge structure 52. The second filling and draining device 53 is disposed on the floating platform 1 and is used to fill and drain the second regulating water tank. Based on this structure, the second regulating water tank can be filled and drained by the second filling and draining device 53. For example, when filling the second regulating water tank, the other end of the door leaf structure 51 away from the hinge structure 52 can sink, and when draining the second regulating water tank, the other end of the door leaf structure 51 away from the hinge structure 52 can float.

[0064] For example, such as Figure 5As shown, the second filling and draining device 53 may include a second air compressor 531, a second inlet trash rack 532, and a second electric gate valve 533. The second air compressor 531 is installed on the floating platform 1, and the second inlet trash rack 532 and the second electric gate valve 533 are installed on the gate structure 51, with the second inlet trash rack 532 and the second electric gate valve 533 being correspondingly arranged. The second air compressor 531 can be bolted to the inside of the floating platform 1 to save space. The second inlet trash rack 532 can be installed at the inlet of the gate structure 51 to prevent dirt in the water from entering the gate structure 51 and affecting the normal operation of the equipment.

[0065] Based on this structure, when the second electric gate valve 533 is opened and the second air compressor 531 is closed, external water can flow into the second regulating water tank of the gate structure 51 by gravity, thereby causing the other end of the gate structure 51 away from the hinge structure 52 to sink; when the second electric gate valve 533 is opened and the second air compressor 531 is turned on, the water in the second regulating water tank of the gate structure 51 can be forcibly discharged to the outside, thereby causing the other end of the gate structure 51 away from the hinge structure 52 to float.

[0066] For example, such as Figure 3 and Figure 5 As shown, the floating platform 1 may have a door storage compartment 11 facing the bottom sill 7. One end of the hinge structure 52 is connected to the inner wall of the door storage compartment 11, and the door leaf structure 51 is embedded in the door storage compartment 11 when it is not in operation. A locking device 200 is provided on the inner wall of the door storage compartment 11 away from the hinge structure 52, and the locking device 200 is snap-fitted to the other end of the door leaf structure 51. For example, the locking device 200 may include a snap-fit ​​element, and the other end of the door leaf structure 51 away from the hinge structure 52 is provided with a slot that matches the snap-fit ​​element. Through the cooperation of the snap-fit ​​element and the slot, the door leaf structure 51 can be fixed flat in the door storage compartment 11.

[0067] Based on this structure, in the open state, the door leaf structure 51 can lie flat on the bottom of the floating platform 1 through the locking device 200, and the bottom of the door leaf structure 51 is flush with the bottom of the floating platform 1, which helps to eliminate the obstruction of the water flow by the door leaf structure 51. At the same time, the door leaf structure 51 and the hinge structure 52 can be inspected and maintained during the low water level period. When the locking device 200 is released, the door leaf structure 51 is filled with water and begins to sink until the lower edge of the door leaf structure 51 abuts against the bottom sill 7, thereby blocking the water flow.

[0068] For example, such as Figure 3As shown, the bottom sill 7 can also be provided with a water-blocking protrusion 71. When the other end of the door leaf structure 51 sinks, it abuts against the water-blocking protrusion 71, which helps to improve the stability of water blocking. Based on this structure, when the locking device 200 is released, the door leaf structure 51 is filled with water and begins to sink until the lower edge of the door leaf structure 51 abuts against the water-blocking protrusion 71, thereby playing a role in blocking the water flow.

[0069] For example, the exterior of the water-retaining protrusion 71 can be covered with a steel plate, which can further improve the strength of the water-retaining protrusion 71.

[0070] like Figure 4 As shown, in some embodiments, the floating gate may further include a spherical bearing 6. The floating platform 1 is rotatably connected to the support column 2 via the spherical bearing 6. The floating platform 1 is provided with an equipment compartment 12, and the drive device 4 is disposed in the equipment compartment 12. The spherical bearing 6 may be disposed between the support column 2 and the floating platform 1. The allowable tilt angle of the spherical bearing 6 may be 2.5 degrees, and there is a gap between the inner ring of the spherical bearing 6 and the support column 2 to accommodate the attitude changes of the floating platform 1 during rotation or sinking.

[0071] like Figure 4 As shown, in some embodiments, the support column 2 may include a bottom embedded part 21 and a second column 22 connected to the bottom embedded part 21. The bottom embedded part 21 is connected to the bottom sill 7, and the second column 22 is rotatably connected to the floating platform 1. Based on this structure, the floating platform 1 can be driven to rotate relative to the second column 22 by the driving device 4.

[0072] For example, such as Figure 4 As shown, the drive device 4 may include a hydraulic motor 41, a pinion 42, a gear 43, and a base 44. The base 44 can be bolted to the floating platform 1. The hydraulic motor 41, pinion 42, and gear 43 are disposed on the base 44. The output shaft of the hydraulic motor 41 is rotatably connected to the pinion 42. The pinion 42 meshes with the gear 43. The gear 43 is fixedly connected to the upper end of the second column 22. The hydraulic motor 41 can drive the floating platform 1 to rotate relative to the second column 22.

[0073] The floating gate provided in this embodiment has its axis parallel to the water flow direction when the gate is open. The gate body 001 can also serve as the gate pier 100, and the openings between the gate bodies 001 can meet the requirements for flow passage and navigation. When a closing command is received, water is first drained into the floating column 3, causing the floating platform 1 to float as a whole. Then, the drive device 4 is turned on to drive the floating platform 1 to rotate and close the gate. After the gate is closed, the floating column 3 is filled with water and sinks, locking itself in the positioning hole 8. Then, the locking device 200 of the floating suspended gate 5 is opened, and the interior of the gate leaf structure 51 is filled with water and sinks until it abuts against the water-blocking protrusion 71 of the bottom sill 7. After all the gate leaf structures 51 have sunk, the opening can be sealed, thus playing a role in resisting floods from the outer river.

[0074] This floating gate makes full use of hydraulic characteristics and is very suitable for water retention needs of large orifices and ultra-large span orifices. It is lightweight, flexible in opening and closing, safe and reliable, and has good landscape effect, which has far-reaching significance in the field of water conservancy and hydropower engineering.
