Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, specifically to a hinge device that adapts to the operating posture of a floating gate. Background Technology

[0002] Floating gates are a type of special gate that uses buoyancy to achieve opening and closing functions. They are widely used in water conservancy projects such as tide gates and flood control gates. They are often found in areas with complex hydrological conditions and special geographical environments, such as shallow wetlands and river deltas, and play important functions such as flood control, drainage, disaster reduction and bank protection.

[0003] Most current mainstream floating gates are connected to the gate wall via hinged structures. During operation, they rely solely on a single-sided hinged structure for constraint control, resulting in weak overall control capabilities, high sensitivity to wind and wave loads, and susceptibility to external hydrological interference. Simultaneously, with the continuous expansion of water conservancy projects, the design span of floating gates is constantly exceeding conventional limits, further highlighting the inherent defects of traditional hinged structures. This exacerbates the compatibility contradiction between the floating gate and the gate wall: because the gate wall is a fixed rigid structure, when the floating gate undergoes dynamic movements such as lateral tilting, longitudinal tilting, and heaving under buoyancy, the gate wall cannot adjust in tandem with the gate's real-time movement, making it difficult to provide stable and effective dynamic constraints. This problem directly leads to the inability of traditional hinged structures to meet the higher requirements of current water conservancy projects for the operational stability and attitude controllability of floating gates, becoming a key bottleneck restricting the technological upgrading and engineering application expansion of floating gates. Summary of the Invention

[0004] In view of the deficiencies of the prior art described above, the technical problem to be solved by the present invention is to provide a hinge device that adapts to the operating posture of a floating gate, and can be coordinated to adjust the lateral tilt, longitudinal tilt, and buoyancy movements caused by wind and waves during the opening and closing of the floating gate.

[0005] To achieve the above objectives, the present invention provides a hinge device adapted to the operating posture of a floating gate, used to connect the gate wall and the floating gate. The hinge device includes a fixed support, a connecting mechanism, and a movable support. The fixed support is fixedly connected to the gate wall, and the movable support is fixedly connected to the floating gate. The fixed support is hinged to the movable support through the connecting mechanism. The connecting mechanism includes a vertical shaft, a horizontal shaft, a spherical bearing, and a sliding bearing. A bearing seat is fixedly provided at one end of the horizontal shaft. The spherical bearing is disposed in the bearing seat of the horizontal shaft and is fitted onto the vertical shaft. The outer ring of the spherical bearing is configured with an interference fit to the bearing seat, and the inner ring of the spherical bearing is configured with a clearance fit to the vertical shaft. The fixed support is detachably fixedly connected to the vertical shaft. An installation hole is provided on the movable support. The sliding bearing is fitted onto the end of the horizontal shaft away from the bearing seat and is detachably installed between the horizontal shaft and the installation hole. The outer ring of the sliding bearing is configured with an interference fit to the installation hole, and the inner ring of the sliding bearing is configured with a transition fit to the horizontal shaft.

[0006] Furthermore, the fixed support includes ear seats, anchor plates, and anchor bars. Two ear seats are fixedly provided on one side of the anchor plate, and multiple anchor bars are fixedly provided on the other side. The ear seats are provided with connecting holes, and the two ear seats are arranged vertically at intervals. The vertical shaft is detachably and fixedly connected to the connecting holes of the two ear seats. The joint bearing is located between the two ear seats. One end of the anchor bar is fixedly welded to the anchor plate. The anchor plate and anchor bars are both pre-embedded in the gate wall.

[0007] Furthermore, a limiting groove is provided in the connecting hole of the ear seat, and a limiting component that cooperates with the limiting groove is provided on the vertical shaft.

[0008] Furthermore, the movable support is also provided with a disassembly hole, which is provided on opposite sides of the movable support as well as the mounting hole. The disassembly hole is connected to the mounting hole, and the diameter of the disassembly hole is larger than the diameter of the mounting hole.

[0009] Furthermore, the connecting mechanism also includes a buffer pad, a shaft end baffle, and fastening bolts. Threaded holes are provided on the buffer pad, the shaft end baffle, and the end face of the horizontal shaft away from the bearing seat. The buffer pad and the shaft end baffle are screwed to the end face of the horizontal shaft by fastening bolts. The buffer pad and the shaft end baffle are both circular in shape, and the diameter of the buffer pad and the diameter of the shaft end baffle are both smaller than the diameter of the disassembly hole, while the diameter of the shaft end baffle is larger than the diameter of the mounting hole.

[0010] Furthermore, the movable support includes a box base and a box shell. The box base is provided with mounting holes and disassembly holes. The box base is also provided with a wedge-shaped block that is narrower at the top and wider at the bottom. The box shell is provided with a sliding groove running from top to bottom. The side of the sliding groove is provided with a wedge-shaped surface that is wider at the top and narrower at the bottom and cooperates with the wedge-shaped block. The box shell is fixedly welded to the floating gate.

[0011] Furthermore, the movable support also includes a support member and a pressure cap disposed on the support member. The support member includes two spaced-apart support columns, the bottom ends of which are fixedly connected to the housing shell. The pressure cap includes a pressure plate and a pressure column. The pressure plate is bolted to the top of the support column. The top of the pressure column is fixedly welded to the pressure plate, and the bottom end abuts against the housing base.

[0012] Furthermore, the pressure cap also includes a rubber block, which is bolted to the bottom end of the pressure column.

[0013] Furthermore, lifting lugs are provided on the vertical shaft, the housing base, and the pressure plate.

[0014] Furthermore, the vertical shaft is made of low-alloy high-strength structural steel.

[0015] As described above, the hinge device for adapting to the operating posture of a floating gate, as disclosed in this invention, has the following beneficial effects:

[0016] By setting fixed supports, connecting mechanisms, and movable supports, the hinge device can be coordinated to adjust the lateral, longitudinal, and buoyancy movements caused by wind and waves during the opening and closing of the floating gate. This has far-reaching significance for its application in large-span floating gate projects. By setting the hinge device as a detachable structure, the connecting structure can be easily removed from the fixed and movable supports during non-flood control periods and when the floating gate is not in operation, which facilitates maintenance and repair, thereby improving its service life.

[0032] See Figures 1 to 9 This invention provides a hinge device adapted to the operating posture of a floating gate, used to connect a gate wall 1 and a floating gate 2. The hinge device includes a fixed support 3, a connecting mechanism 4, and a movable support 5. The fixed support 3 is fixedly connected to the gate wall 1, and the movable support 5 is fixedly connected to the floating gate 2. The fixed support 3 is hinged to the movable support 5 through the connecting mechanism 4. The connecting mechanism 4 includes a vertical shaft 401, a horizontal shaft 402, a spherical bearing 403, and a sliding bearing 404. A bearing seat 405 is fixedly provided at one end of the horizontal shaft 402, and the spherical bearing 403 is disposed in the bearing seat 405 of the horizontal shaft 402 and is fitted onto the... On the vertical shaft 401, the outer ring of the spherical plain bearing 403 is configured with an interference fit to the bearing housing 405, and the inner ring of the spherical plain bearing 403 is configured with a clearance fit to the vertical shaft 401. The fixed support 3 is detachably fixedly connected to the vertical shaft 401. The movable support 5 is provided with a mounting hole 501. The sliding bearing 404 is fitted onto the end of the horizontal shaft 402 away from the bearing housing 405, and the sliding bearing 404 is detachably installed between the horizontal shaft 402 and the mounting hole 501. The outer ring of the sliding bearing 404 is configured with an interference fit to the mounting hole 501, and the inner ring of the sliding bearing 404 is configured with a transition fit to the horizontal shaft 402.

[0033] The basic working principle of the hinge support device for adapting to the operating posture of a floating gate involved in this invention is as follows: During use, by setting a fixed support 3, a connecting mechanism 4, and a movable support 5, it can operate underwater and can coordinately adjust to the lateral, longitudinal, and buoyancy movements caused by wind and waves during the opening and closing of the floating gate 2; see attached drawings. Figure 1 XOY coordinate system Figure 2 XYZ coordinate system Figure 3The XOZ coordinate system, wherein, by setting a spherical bearing 403, on the one hand, the outer ring of the spherical bearing 403 is rigidly connected to the horizontal shaft 402, and the inner and outer rings adopt a spherical fit, which can satisfy the small-angle rotation of the horizontal shaft 402 in any direction; on the other hand, the inner ring of the spherical bearing 403 is clearance-fitted with the vertical shaft 401, and there is a preset radial clearance between the inner ring and the vertical shaft 401, which can satisfy the small-range displacement of the horizontal shaft 402 in the horizontal plane and the displacement in the vertical direction, so that the hinge device can adapt to the rotation of the floating gate 2 around the Z-axis, the small-angle rotation around the X and Y axes, the small-range movement in the XY plane, and the floating and sinking movement along the Z-axis; by setting a sliding bearing 404. On the one hand, the sliding bearing 404 is rigidly connected to the movable support 5, and the inner ring of the sliding bearing is transitionally fitted with the horizontal shaft 402, which can satisfy the large-angle rotation deformation of the movable support 5 around the X-axis. On the other hand, there is a preset axial clearance between the end of the sliding bearing 404 and the shaft end baffle 407, which can satisfy the small-range axial displacement of the movable support 5 along the horizontal shaft 402, so that the hinge device can adapt to the rotation of the floating gate 2 around the X-axis and the small-range displacement along the X-axis. By setting the hinge device as a detachable structure, during non-flood control periods and when the floating gate 2 is not in operation, the connecting mechanism 4 can be easily removed from the fixed support 3 and the movable support 5, which facilitates maintenance and repair, thereby improving its service life.

[0034] See Figures 1 to 9 The present invention will be further described below with reference to a specific embodiment:

[0035] In this embodiment, see Figure 1 , Figure 2 , Figure 3 , Figure 4As a preferred design, the fixed support 3 includes ear seats 301, anchor plates 302, and anchor bars 303. Two ear seats 301 are fixedly installed on one side of the anchor plate 302, and multiple anchor bars 303 are fixedly installed on the other side. The ear seats 301 are provided with connecting holes, and the two ear seats 301 are spaced apart vertically. The vertical shaft 401 is detachably fixedly connected to the connecting holes of the two ear seats 301. The spherical bearing 403 is located between the two ear seats 301. Preferably, a circular end plate is fixedly installed at the top of the vertical shaft 401. The diameter of the circular end plate is larger than the diameter of the vertical shaft 401. The circular end plate presses against the ear seat 301 located above, which can improve the stability of the connection between the vertical shaft 401 and the ear seat 301. Specifically, the two ear seats 301 The net distance between them can be flexibly set according to the floating height required during the operation of the floating gate 2. Both ear seats 301 adopt an empty box structure. One end of the anchor bar 303 is fixedly welded to the anchor plate 302. Preferably, one end of the anchor bar 303 is fixed to the anchor plate 302 by plug welding. The anchor plate 302 and the anchor bar 303 are both pre-embedded in the gate wall 1. Specifically, the material of the gate wall 1 is concrete. Through the fixed support 3, all external loads on the hinge device can be transferred to the concrete. Preferably, the end of the anchor bar 303 away from the anchor plate 302 is provided with a hook structure, which can effectively increase the bond force between the anchor bar 303 and the concrete, thereby improving the overall bearing capacity and seismic performance between the gate wall 1 and the fixed support 3.

[0036] In this embodiment, see Figure 2 , Figure 3 , Figure 4 As a preferred design, the connecting hole of the ear seat 301 is provided with a limiting groove, and the vertical shaft 401 is provided with a limiting component that cooperates with the limiting groove. When the vertical shaft 401 is placed into the connecting hole, by setting the limiting groove and the limiting component, on the one hand, the vertical shaft 401 can be fixedly connected to the two ear seats 301 and prevent the vertical shaft 401 from rotating in the connecting hole of the ear seat 301. On the other hand, it can also facilitate disassembly and improve assembly efficiency.

[0037] In this embodiment, see Figure 6 , Figure 7 As a preferred design, the movable support 5 is also provided with a disassembly hole 502. The disassembly hole 502 and the mounting hole 501 are respectively provided on opposite sides of the movable support 5. The disassembly hole 502 is connected to the mounting hole 501, and the diameter of the disassembly hole 502 is larger than the diameter of the mounting hole 501. Preferably, the shape of the disassembly hole 502 is set as a gate-shaped opening, and the diameter of the largest inscribed circle is larger than the diameter of the mounting hole 501. Through the disassembly hole 502, the detachability of the hinge device can be further optimized.

[0038] In this embodiment, see Figure 5 , Figure 7, As a preferred design, the connecting mechanism 4 further includes a buffer pad 406, a shaft end baffle 407, and a fastening bolt 408. Threaded holes are provided on the buffer pad 406, the shaft end baffle 407, and the end face of the horizontal shaft 402 away from the bearing seat 405. The buffer pad 406 and the shaft end baffle 407 are both screwed onto the end face of the horizontal shaft 402 through the fastening bolt 408. The shapes of the buffer pad 406 and the shaft end baffle 407 are both circular, and the diameters of the buffer pad 406 and the shaft end baffle 407 are both smaller than the diameter of the disassembly hole 502, and the diameter of the shaft end baffle 407 is larger than the diameter of the installation hole 501. Preferably, the buffer pad 406 is located between the end face of the horizontal shaft 402 and the shaft end baffle 407. There is a small axial side clearance between the sliding bearing 404 and the buffer pad 406, enabling the hinge device to further adapt to the lateral displacement of the floating gate 2 during the rotational movement due to the action of wind and waves. The buffer pad 406 can also play a buffering role, thereby reducing the impact of the impact load on the fastening bolt 408. The shaft end baffle 407 can play an axial limiting role to prevent the horizontal shaft 402 from slipping out of the installation hole 501 of the movable support 5. Specifically, when the movable support 5 and the horizontal shaft 402 are removed as a whole, the fastening bolt 408 on the end face of the horizontal shaft 402 can be unscrewed through the disassembly hole 502, thereby disassembling the horizontal shaft 402 from the movable support 5.

[0039] In this embodiment, refer to Figure 6 , Figure 7 , Figure 8 , As a preferred design, the movable support 5 includes a box seat 503 and a box shell 504. The box seat 503 is provided with an installation hole 501 and a disassembly hole 502. The box seat 503 is further provided with a wedge-shaped block 505 that is narrower at the top and wider at the bottom. The box shell 504 is provided with a chute from top to bottom, and the side of the chute is provided with a wedge surface that is wider at the top and narrower at the bottom and is matched with the wedge-shaped block 505. The box shell 504 is fixedly welded to the floating gate 2. Preferably, the shape of the box seat 503 is set as a "convex" shape, and multiple wedge-shaped blocks 505 are provided on the box seat 503. The shape of the box shell 504 is set as a "concave" shape, and wedge surfaces that are matched with multiple wedge-shaped blocks 505 are provided on the box shell 504. During use, when the box seat 503 slides downward into the chute of the box shell 504, under the action of the self-weight of the box seat 503, the wedge-shaped block 505 that is narrower at the top and wider at the bottom and the wedge surface that is wider at the top and narrower at the bottom will be gradually wedged tightly. On the one hand, the connection is firm and reliable. On the other hand, no complex tools are required for disassembly, and the installation and disassembly are convenient and efficient, further optimizing the detachable property of the hinge device.

[0040] In this embodiment, refer to Figure 9As a preferred design, the movable support 5 also includes a support member and a pressure cap disposed on the support member. The support member includes two spaced-apart support columns 506, the bottom ends of which are fixedly connected to the housing shell 504. Preferably, the two support columns 506 are symmetrically disposed on the housing shell 504 along the Y-axis. The pressure cap includes a pressure plate 507 and a pressure column 508. The pressure plate 507 is bolted to the top of the support column 506. The top of the pressure column 508 is fixedly welded to the pressure plate 507, and the bottom end abuts against the housing seat 503. The support member and the pressure cap can prevent the housing seat 503 from separating from the housing shell 504 during the floating gate 2's floating or sinking process. Preferably, there are two support members and two pressure caps, and the two support members are symmetrically disposed on the housing shell 504 along the X-axis.

[0041] In this embodiment, see Figure 9 As a preferred design, the pressure cover also includes a rubber block 509, which is bolted to the bottom of the pressure column 508. This can prevent rigid collisions and abnormal noises between the box seat 503 and the pressure column 508 during the floating gate 2's ascent or descent.

[0042] In this embodiment, see Figure 2 As a preferred design, lifting lugs 510 are provided on the vertical shaft 401, the box seat 503, and the pressure plate 507. Preferably, the lifting lugs 510 on the vertical shaft 401, the box seat 503, and the pressure plate 507 are all located above the water surface, so that the pressure plate, the vertical shaft 401, and the box seat 503 can be easily lifted out when disassembly is required, thus improving the efficiency of disassembly.

[0043] In this embodiment, see Figure 1 , Figure 2 As a preferred design, the vertical shaft 401 is made of low-alloy high-strength structural steel. Preferably, the vertical shaft 401 is made of rolled steel plate, and the outer circumference of the vertical shaft 401 is chrome-plated or laser-plated with stainless steel, which can effectively reduce the frictional resistance of the rotation and floating motion of the floating gate 2. In other embodiments, the vertical shaft 401 can also be made of rolled stainless steel plate. Since the hinge device is located in the water level change zone, the use of rolled stainless steel plate can give the vertical shaft 401 strong corrosion resistance.

[0044] As described above, the hinge device method for adapting to the operating posture of a floating gate, as disclosed in this invention, has the following beneficial effects:

[0045] By setting up fixed support 3, connecting mechanism 4, and movable support 5, the hinge device can be coordinated to adjust the lateral tilt, longitudinal tilt, and buoyancy movements caused by wind and waves during the opening and closing of the floating gate 2. This has far-reaching significance for the application of large-span floating gate 2 projects. By setting the hinge device as a detachable structure, the connecting structure can be easily removed from the fixed support 3 and movable support 5 during non-flood control periods and when the floating gate 2 is not in operation, which facilitates maintenance and repair and improves its service life.

[0046] In summary, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0047] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
