Description
Technical Field
[0001] The invention relates to the field of water conservancy and hydropower engineering, and in particular to an adaptive anti-heeling super-large floating gate driving device and method. Background Art
[0002] In the field of water conservancy projects, the demand for the construction of extra-large gates is becoming increasingly prominent in order to meet the functional requirements of tide blocking, flood control, and water resource allocation. Especially in the face of complex conditions with wide rivers and deep water, the floating gate design has become a highly concerned solution due to its advantage of significantly reducing the opening and closing capacity. However, once it involves an extra-large floating gate with an opening width of more than 200m, the technical difficulties faced during its design, construction, and construction are enormous.
[0003] This type of super-large floating gate has extremely high requirements for the drive system. It not only has to cope with huge loads, but also needs to meet the operation requirements of long strokes, and will be subjected to complex and variable hydraulic loads during operation. At the same time, since the water flow resistance of the floating gate is located underwater during operation, the drive system is usually located above the water surface for easy maintenance and repair. Therefore, the overturning moment needs to be balanced by the anti-overturning moment. The current mainstream gate drive technology, such as hydraulic hoists and connecting rod hoists, has been successfully applied in many water conservancy projects. For example, the miter gates of the Three Gorges ship locks use hydraulic opening and closing, and the miter gates of the Gezhouba No. 2 ship lock use connecting rod hoists. However, they are unable to cope with such stringent drive requirements of super-large floating gates. Summary of the invention

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0051] like Figures 1 to 6 As shown, an embodiment of the present invention provides an adaptive anti-rolling extra-large floating gate driving device, including a connecting arm 1, a driving system 2, an anti-rolling system 3, and a track system 4.
[0052] like Figure 1 As shown, the connecting arm 1 includes a triangular truss 102, one vertex of the triangular truss 102 is installed on the ball joint support provided on both sides, and the two vertices on the other side are connected to the floating gate through the support hinge.

The driving system 2 and the heeling system 3 are installed on the track system 4.
[0053] like Figure 2As shown, the connecting arm 1 is provided with a central ball joint 101, which is installed on the ball joint supports arranged on both sides, and can realize circular motion around the central ball joint and adapt to the longitudinal swing of the gate. The connecting arm 1 structure is composed of a triangular truss 102 to ensure the rigidity of the arm, and the connecting arm 1 is connected to the floating gate through the gate hinge 104. The two side arms of the connecting arm 1 are each provided with two sets of push sliders 103, which are used to transfer the driving load from the driving system 2 and the anti-rolling system 3 to the connecting arm 1, and finally drive the floating gate.
[0054] like Figure 3 As shown, the driving system includes a frame 201, a motor 202, a coupling 203, a working brake 204, a reducer 205, an open gear 209 and a horizontal guide wheel 210. The frame 201 is provided with a motor frame for installing the motor 202. The output shaft of the motor 202 is connected to the reducer 205 through the coupling 203, wherein the coupling 203 is provided with a brake disc and a working brake 204, and the working brake 204 can provide braking force during operation. An open gear 209 is provided at the end of the reducer 205, which meshes with the ring gear 401 in the track system 4 to provide driving force for the opening and closing of the gate. A horizontal guide wheel 210 is provided on the other side of the gear 209, which can roll on the horizontal guide rail 402 to ensure that the meshing relationship between the open gear 209 and the ring gear 401 is not affected by sudden loads such as wind, waves, and water flow. The horizontal guide wheel 210 is installed on the frame 201 through a guide wheel support seat 211. A driving system wheel support seat 207 is provided at the bottom of the frame 201 for mounting a driving system support wheel 208, and is mounted on the support wheel track 403 of the track system 4. Two sets of horizontal elastic supports 206 are provided at both ends of the frame 201, such as Figure 5 As shown, the horizontal elastic support 206 includes an elastic rubber pad 206-1 and a metal support plate 206-2, wherein the elastic rubber pad 206-1 is in contact with the gantry of the anti-roll system 3, and a buffer can be set between the anti-roll system 3 and the drive system 2 to avoid impact loads under extreme working conditions.
[0055] like Figure 4 As shown, the anti-roll system 3 includes a left gantry 301, a right gantry 305, and a truss 303 connecting the left gantry 301 and the right gantry 305. A support is provided at the top of the left gantry 301 for installing the left oil cylinder 302, and a cross-circuit connection is set with the right oil cylinder 304 provided at the top of the right gantry 305, that is, the upper cavity of the left oil cylinder 302 is connected with the lower cavity of the right oil cylinder 304 through an oil pipe, and the lower cavity of the left oil cylinder 302 is connected with the upper cavity of the right oil cylinder 304 through an oil pipe. The left oil cylinder 302 and the right oil cylinder 304 are both double-rod oil cylinders, and the upper and lower cavity sections are the same. The piston rods of the left oil cylinder 302 and the right oil cylinder 304 are hinged to the connecting arm 1, and the hinge direction thereof is orthogonal to the hinge direction of the top of the gantry and the cylinder body.
[0056] The cross-circuit hydraulic cylinders can move up and down freely synchronously. Figure 7 As shown, when the piston rods on both sides are pulled downward, the hydraulic oil in the lower cavity of the left cylinder 302 is pressurized to flow to the upper cavity of the right cylinder 304, and the hydraulic oil in the lower cavity of the right cylinder 304 is pressurized to flow synchronously to the upper cavity of the left cylinder 302, realizing the function of synchronous movement to adapt to the floating and sinking movement during the operation of the floating gate. The stroke tolerance of the anti-rolling cylinder is ≤10mm, and the heel angle compensation accuracy of the floating gate is ≤0.05°
[0057] In addition, the cross-circuit cylinders can provide adaptive anti-heeling force. Figure 8 As shown, when a heeling force occurs during operation, that is, the cylinders on both sides are subjected to equal reverse forces to balance the heeling force couple, taking the example of the cylinder rod of the left cylinder 302 being subjected to downward pulling force and the cylinder rod of the right cylinder 304 being subjected to upward pressure. The cylinder rod of the left cylinder 302 has a downward movement trend, and the cylinder rod of the right cylinder 304 has an upward movement trend. At this time, the hydraulic oil in the lower cavity of the left cylinder 302 flows to the upper cavity of the right cylinder 304, and at the same time, the hydraulic oil in the upper cavity of the right cylinder 304 flows to the lower cavity of the left cylinder 302. Since the liquid is incompressible, the cylinder self-locks to provide an anti-heeling moment, and can adaptively provide an anti-heeling moment in the range of 0-139359kN·m.
[0058] Two sets of push rails 306 are respectively provided on the inner pillars of the left gantry 301 and the right gantry 305, which are used to contact and transmit force with the push slider 103. At the same time, the push slider 103 can slide up and down on the push rails 306 to adapt to the ups and downs of the floating gate during operation. The bottom of the left gantry 301 and the right gantry 305 is provided with an anti-rolling system wheel group support seat 307, which is used to install the anti-rolling system support wheel 308 and is installed on the support wheel track 403 of the track system 4.
[0059] like Figure 6 As shown, the track system 4 includes 401, a horizontal guide rail 402, a support wheel track 403, a track platform 404, a mounting base plate 405, and a box beam 406. The mounting base plate 405 is arranged on the track platform 404, the box beam 406 is welded to the mounting base plate 405 and connected with bolts embedded on the track platform 404, and the gear ring 401 and the horizontal guide rail 402 are welded and mounted on both sides of the box beam 406. Support wheel tracks 403 are arranged on both sides of the gear ring 401 and the horizontal guide rail 402 for mounting the support wheels of the drive system 2 and the anti-roll system 3. The gear ring 401, the horizontal guide rail 402, and the support wheel track 403 are all quarter arcs, and the center of the circle is located at the center ball joint 101.
[0060] In order to illustrate the implementation method of the present invention, the embodiment of the present invention takes 4 groups of driving units as an example, and technical solutions using other numbers of driving units should also fall within the scope of the claims of the present invention.
[0061] The running curve is as follows Fig. 9 As shown, the operation mode of 20 minutes or 30 minutes can be adopted according to the use requirements and working conditions. Taking 20 minutes as an example, the initial operation process is the acceleration stage of 60 seconds, and the acceleration is 0.00139 deg / s 2 The uniform motion speed in the middle section is 0.0833 deg / s, and the final section is a deceleration stage of 180s with an acceleration of -0.00046 deg / s 2 . It can realize rapid opening and closing operation within 20 minutes.
[0062] Before the floating gate is closed, it needs to be drained and floated, and the bottom of the gate is separated from the bottom sill and is in a floating state. At this time, the buoyancy of the gate is transmitted to the connecting arm 1 through the connecting door support hinge 104, and the connecting arm 1 rotates around the central ball joint 101 and floats. The left cylinder 302 and the right cylinder 304 are respectively connected to the two sides of the connecting arm 1, and the piston rods of the two cylinders rise synchronously under the upward force of the connecting arm 1. At this time, the push slider 103 slides synchronously on the push rail 306 to reach the driving position.
[0063] When the gate floats to the driving station, the working brakes 204 of each group of drive units in the drive system 2 are disengaged from the brake disc, and the output torque of the motor 202 is transmitted to the input end of the reducer 205 through the coupling 203. The torque is output through the open gear 209 at the end of the reducer 205 and transmitted to the gear ring 401 on the track platform 404 to provide driving force. The support wheel 208 of the drive system rolls along the support wheel track 403, and the four groups of drive units synchronize the frame 201 to make a circular motion around the central ball joint 101. The horizontal elastic support 206 on the end face of the frame 201 drives the anti-rolling system 3 after buffering. The push rail 306 of the anti-rolling system 3 contacts the push slider 103 on the connecting arm 1 and transmits the driving force to the floating gate.
[0064] During operation, sudden loads caused by wind, waves, and currents can cause the gate to sink or float. At the same time, the driving force elevation is higher than the water flow resistance elevation, causing an overturning moment. The upper and lower cavities of the left cylinder 302 and the upper and lower cavities of the right cylinder 304 are cross-connected, providing an anti-heeling moment M while also adapting to the sinking and floating movement of the gate, ensuring safe and reliable operation of the gate. The anti-heeling moment M satisfies:
[0065] M=F q *ΔH=ΔF*L=k*Δh
[0066] where F q is the driving force, ΔH is the height difference between the driving force and the equivalent resistance of the floating valve, ΔF is the pressure difference of the cylinder, L is the distance between the cylinders, k is the system stiffness coefficient, and Δh is the heel displacement.
[0067] The control range of the anti-roll moment M is 0~139359kN·m, the tolerance of the anti-roll cylinder is ≤10mm, and the heel angle compensation accuracy is ≤0.05°
[0068] When the floating gate is about to run to the closing position, the motor 202 enters the power generation state, and its torque is transmitted to the reducer 205 through the coupling 203, and then transmitted to the gear ring 401 by the open gear 209 at the end of the reducer 205 to provide holding force. The four sets of drive units on the frame 201 brake synchronously, and the horizontal elastic support 206 at the other end of the frame 201 transmits the braking load to the anti-roll system 3 after buffering, and the other side push rail 306 and the push slider 103 transmit the braking load to the connecting arm 1 and the gate. When the gate is about to run to the closing position, the floating gate is filled with water and sinks. At this time, the left cylinder 302 and the right cylinder 304 of the anti-roll system 3 descend with the connecting arm 1 until the bottom of the gate is at the bottom sill.
[0069] The operation process of the driving device during the opening process of the floating gate is opposite to the closing operation mode.
[0070] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
