Description

Technical Field

[0001] The invention relates to the technical field of gates, and in particular to a self-floating gate. Background Art

[0002] Ordinary gates cannot adjust the opening in real time and need to switch the electronic control system back and forth for adjustment; ordinary gates are powered by hydraulic cylinders, and the hydraulic extension rods are easily exposed to corrosion and wear, resulting in a short service life and poor economy; opening ordinary gates requires personnel to carry operating tools back and forth, which is labor-intensive. Summary of the invention

[0003] The object of the present invention is to provide a self-floating gate to solve at least one of the above problems existing in the prior art.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A self-floating gate comprises a chamber, a gate seat and a gate, wherein the gate seat is installed at the bottom of the chamber, the gate is a hollow structure, one end of the gate is hinged to the gate seat, the chamber located on the left side of the gate is the left chamber, the chamber located on the right side of the gate is the right chamber, a lower limit block is provided at the bottom of the left chamber, and the gate abuts against the lower limit block when it rotates to the minimum angle, and upper limit blocks are provided on the two side walls of the chamber, and the gate abuts against the upper limit blocks when it rotates to the maximum rotation angle;

[0006] Side seals are symmetrically provided on both sides of the gate, and the side seals are tightly fitted and pressed on the side walls of the chamber to prevent liquid from flowing into the right chamber from the side of the gate. A fixed seat is provided at the bottom of the chamber, and the fixed seat is located near the rotating end of the gate. A bottom seal is provided on the fixed seat, and the length direction of the bottom seal is consistent with the width direction of the gate. The free end of the bottom seal is tightly fitted and pressed on the rotating end of the gate to prevent liquid from flowing into the right chamber at the bottom of the gate.

[0007] In this technical solution, since the gate is a hollow structure, when there is liquid at the bottom of the gate, the gate will discharge the liquid, and the liquid at the bottom of the gate will form a buoyancy on the gate as a whole upward, and the buoyancy provides a direct power source for the gate to float; since one end of the gate is hinged to the gate seat, the buoyancy generated by the liquid on the gate forms a torque relative to the hinge position of the gate, so that the gate rotates around the gate seat and floats the gate; since a lower limit block is provided at the bottom of the left chamber, the gate abuts against the lower limit block when it rotates to the minimum angle, that is, when there is no liquid in the left chamber, the gate rests on the lower limit block, so that a cavity can be formed at the lower part of the gate, which is easy to float when there is liquid; since upper limit blocks are provided on the two side walls of the chamber, the gate abuts against the upper limit blocks when it rotates to the maximum rotation angle, and the upper limit blocks can limit the extreme position of the gate floating to isolate the liquid in the left chamber from passing through the gate.

[0008] Since the gate is symmetrically provided with side seals on both sides, the side seals are tightly fitted and pressed on the side wall of the chamber, and are used to isolate the liquid from the side of the gate from flowing into the right chamber. When the waterline is below the side seals, the side seals and the side wall of the chamber are tightly fitted, and the two are squeezed to deform the side seals. This deformation can isolate the liquids in the left and right chambers of the gate from flowing to each other, thus playing a sealing role. Since a fixed seat is provided at the bottom of the chamber, the fixed seat is located near the rotating end of the gate, and a bottom seal is provided on the fixed seat. The length direction of the bottom seal is consistent with the width direction of the gate. The free end of the bottom seal is tightly fitted and pressed on the rotating end of the gate, and is used to isolate the liquid at the bottom of the gate from flowing into the right chamber through the bottom gap. The setting of the side seals and the bottom seals can ensure the sealing of the left and right chambers during the movement of the gate.

[0009] In summary, the technical solution provides a power source through the volume of liquid displaced by the gate itself. As the liquid level rises, the volume of the displaced liquid increases. The buoyancy overcomes the gate's own weight, the friction resistance between the side seal and the side wall, and the friction resistance between the gate and the bottom seal. It floats when the fluid level in the left chamber rises and sinks when the fluid level in the left chamber drops. It adaptively adjusts the angle of floating and follows the changes in the liquid level, thereby controlling the liquid level in the left chamber of the gate.

[0010] This technical solution is mainly used in places where liquid level needs to be adjusted, such as cave openings, dam openings or pipe openings. The liquid level adjustment adopts self-floating adjustment. Under normal circumstances, the equipment itself can complete the adjustment of the fluid liquid level height in the left chamber of the gate, and adapt to the change of liquid level. It only relies on the buoyancy of the gate itself to provide a power source without additional power. The buoyancy of the gate is provided by the height of the liquid level, thereby controlling the rotation of the gate, controlling its own floating and sinking, and isolating the liquid level of the left and right chambers of the gate. The gate opening can be freely adjusted by relying solely on the buoyancy of the fluid on the gate, and the gate's own posture can be adjusted and the liquid level can be controlled. No additional power input is required, and there is no need for the electric gate to be adjusted back and forth. The equipment combination can be freely matched.

[0011] Furthermore, the chamber is provided with side light plates on both sides, and the side seals are in contact with the side light plates. The contact surface between the side light plates and the side seals is a smooth surface structure, and the smooth surface friction is small when floating, and the friction torque is smaller than the buoyancy torque, and the side seals rotate with the gate.

[0012] Furthermore, the side seal is arranged on the upper part of the gate side wall. The side seal is connected to the upper part of the gate, and a cavity is formed below the side seal. When the waterline is below the side seal, the volume of the displaced liquid is relatively larger, which can provide greater buoyancy.

[0013] Furthermore, in order to achieve a better side sealing effect, the side seal includes an integrally formed annular sealing portion and an extended sealing strip. The annular sealing portion is fixed to the side end of the rotating end of the gate, and the extended sealing strip extends from the annular sealing portion along the length direction of the gate. That is, the side seal is in the shape of a number 6. Specifically, the gate and the side seal are connected as a whole by bonding or bolting.

[0014] Furthermore, the bottom seal and the side seal are both made of soft sealing material, and the free end of the bottom seal is a cylindrical end. The cylindrical end is tangent to the outer circular frame of the rotating end of the gate end, and maintains a certain deformation and pre-pressure during installation, maintains contact with the gate, and isolates the liquid at the bottom of the gate from flowing into the right chamber of the gate through the bottom gap, forming a bottom seal.

[0015] Furthermore, the free end of the gate is a raised end, which can provide greater buoyancy.

[0016] Furthermore, in order to ensure the fluid flowability of the left and right sides of the gate under special conditions, a hydraulic drive mechanism is used to force the floating angle of the gate. The force of the hydraulic drive mechanism overcomes the buoyancy of the gate, the friction resistance between the side seal and the side light plate, and the friction resistance between the gate and the bottom seal to push the gate to a suitable position to maintain the fluid flow between the left and right chambers. It also includes a hydraulic drive mechanism, the hydraulic drive mechanism includes a hydraulic fixed support and a hydraulic cylinder, the hydraulic fixed support is installed at the bottom of the right chamber, the hydraulic fixed support is provided with a hydraulic hinge seat, and the hydraulic hinge seat is provided with an upper limit rod and a lower limit rod;

[0017] A top claw is provided on the hydraulic extension rod of the hydraulic cylinder, and the top claw is in an eight-shaped shape. The middle part of the hydraulic cylinder is rotatably connected with the hydraulic hinge seat. A limit swing rod is provided on the hydraulic cylinder, and the limit swing rod is located between the upper limit rod and the lower limit rod. The upper limit rod and the lower limit rod respectively limit the swing angle of the limit swing rod;

[0018] A gate hinge seat is provided on the back of the gate, and a gate hinge shaft is rotatably connected to the gate hinge seat. When the hydraulic extension rod of the hydraulic cylinder is extended, the top claw presses on the gate hinge shaft to push the gate toward the left chamber.

[0019] The hydraulic cylinder pushes the back of the gate, and after pushing the gate to the left limit position, the hydraulic cylinder opens the pressure-maintaining state to limit the gate to a fully open state to prevent the gate from being lifted by buoyancy.

[0020] In this technical solution, the hydraulic extension rod has no contact with the gate, which reduces the rust and wear caused by the hydraulic extension rod contacting the fluid due to long-term exposure of the hydraulic extension rod, thereby increasing the service life of the equipment.

[0021] Furthermore, it also includes a power storage system, which supplies power to a hydraulic control system, and the hydraulic control system controls the movement of the hydraulic cylinder.

[0022] Ordinary gates need to be connected to the mains to adjust the opening, and their use in the wild is limited. In this technical solution, in an emergency state, the left and right fluids need to be connected to each other. At this time, photovoltaic panels are used to collect energy, and light energy is converted into electrical energy and stored in the power storage system. The power storage system is only used in an emergency state. It provides an energy source for the control system and the hydraulic power station. The control system controls the operation of various components inside the hydraulic power station. The hydraulic power station supplies hydraulic oil to the hydraulic cylinder through internal pipelines. The hydraulic extension rod extends to drive the top claw, which presses on the gate hinge shaft to push the gate downward. When the emergency state is lifted, the hydraulic extension rod completes the retraction and returns to the initial position to wait for the next emergency command. The gate relies on its own buoyancy to complete the purpose of controlling the liquid level.

[0023] Photovoltaic panels, city electricity, wind power or other energy supply systems are used to provide equipment with power storage systems. The power storage system can be used normally or as a backup energy source.

[0024] Furthermore, in order to better realize the fixed connection of corresponding components, the hydraulic articulated seat is fixedly installed on the upper end of the hydraulic fixed support by bolts, the gate hinge seat is welded or bolted to the back of the gate, and a hydraulic fixed hinge shaft is fixedly provided in the middle part of the hydraulic cylinder. The hydraulic fixed hinge shaft is rotatably connected to the hydraulic articulated seat, and the upper limit rod and the lower limit rod are respectively welded on the hydraulic articulated seat.

[0025] Furthermore, a mounting hole is provided on the gate seat, and a gate main hinge shaft is provided at the rotating end of the gate, and the gate main hinge shaft is rotatably matched with the mounting hole. It also includes a motor reducer or a hydraulic motor with a clutch, and the output shaft of the motor reducer or the hydraulic motor is connected to the gate main hinge shaft through a sprocket chain transmission mechanism, a gear transmission mechanism or a belt transmission mechanism, and its function is to directly drive the gate main hinge shaft to rotate, thereby driving the gate to complete the flipping action. The use of a clutch can close the device and start the device in an emergency state, and can also achieve the above functions. Its power source can directly use the mains, wind power or other energy supply systems to the equipment power storage system, and the power storage system is used in emergency or normal use. In emergency use, the power storage system provides an energy source for the equipment control system and the hydraulic power station. In normal use, it is directly connected to the mains, and the mains drives the hydraulic rod in the device to complete the action.

[0026] The beneficial effects of the present invention are as follows: in this technical solution, since the gate is a hollow structure, when there is liquid at the bottom of the gate, the gate will discharge the liquid, and the liquid at the bottom of the gate will form a buoyancy on the gate as a whole upward, and the buoyancy provides a direct power source for the gate to float; since one end of the gate is hinged to the gate seat, the buoyancy generated by the liquid on the gate forms a torque relative to the hinge position of the gate, so that the gate rotates around the gate seat and floats the gate; since a lower limit block is provided at the bottom of the left chamber, the gate abuts against the lower limit block when it rotates to the minimum angle, that is, when there is no liquid in the left chamber, the gate rests on the lower limit block, so that a cavity can be formed at the lower part of the gate, which is easy to float when there is liquid; since upper limit blocks are provided on the two side walls of the chamber, the gate abuts against the upper limit blocks when it rotates to the maximum rotation angle, and the upper limit blocks can limit the extreme position of the gate floating to isolate the liquid in the left chamber from passing through the gate.

[0027] Since the gate is symmetrically provided with side seals on both sides, the side seals are tightly fitted and pressed on the side wall of the chamber, and are used to isolate the liquid from the side of the gate from flowing into the right chamber. When the waterline is below the side seals, the side seals and the side wall of the chamber are tightly fitted, and the two are squeezed to deform the side seals. This deformation can isolate the liquids in the left and right chambers of the gate from flowing to each other, thus playing a sealing role. Since a fixed seat is provided at the bottom of the chamber, the fixed seat is located near the rotating end of the gate, and a bottom seal is provided on the fixed seat. The length direction of the bottom seal is consistent with the width direction of the gate. The free end of the bottom seal is tightly fitted and pressed on the rotating end of the gate, and is used to isolate the liquid at the bottom of the gate from flowing into the right chamber through the bottom gap. The setting of the side seals and the bottom seals can ensure the sealing of the left and right chambers during the movement of the gate.

[0028] In summary, the technical solution provides a power source through the volume of liquid displaced by the gate itself. As the liquid level rises, the volume of the displaced liquid increases. The buoyancy overcomes the gate's own weight, the friction resistance between the side seal and the side wall, and the friction resistance between the gate and the bottom seal. It floats when the fluid level in the left chamber rises and sinks when the fluid level in the left chamber drops. It adaptively adjusts the angle of floating and follows the changes in the liquid level, thereby controlling the liquid level in the left chamber of the gate.

[0029] This technical solution is mainly used in places where liquid level needs to be adjusted, such as cave openings, dam openings or pipe openings. The liquid level adjustment adopts self-floating adjustment. Under normal circumstances, the equipment itself can complete the adjustment of the fluid liquid level height in the left chamber of the gate, and adapt to the change of liquid level. It only relies on the buoyancy of the gate itself to provide a power source without additional power. The buoyancy of the gate is provided by the height of the liquid level, thereby controlling the rotation of the gate, controlling its own floating and sinking, and isolating the liquid level of the left and right chambers of the gate. The gate opening can be freely adjusted by relying solely on the buoyancy of the fluid on the gate, and the gate's own posture can be adjusted and the liquid level can be controlled. No additional power input is required, and there is no need for the electric gate to be adjusted back and forth. The equipment combination can be freely matched. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0048] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0049] Embodiment 1:

[0050] like Figure 1-Figure 17 As shown, this embodiment provides a self-floating gate, including a chamber, a gate seat 2 and a gate 1, the gate seat 2 is installed at the bottom of the chamber, the gate 1 is a hollow structure, one end of the gate 1 is hinged to the gate seat 2, the chamber located on the left side of the gate 1 is the left chamber 3, the chamber located on the right side of the gate 1 is the right chamber 4, a lower limit block 5 is provided at the bottom of the left chamber 3, and the gate 1 abuts against the lower limit block 5 when it rotates to the minimum angle, and upper limit blocks 6 are provided on the two side walls of the chamber, and the gate 1 abuts against the upper limit block 6 when it rotates to the maximum rotation angle;

[0051] Side seals 7 are symmetrically provided on both sides of the gate 1. The side seals 7 are tightly fitted and pressed on the side walls of the chamber to prevent liquid from flowing into the right chamber 4 from the side of the gate 1. A fixing seat 8 is provided at the bottom of the chamber. The fixing seat 8 is located near the rotating end of the gate 1. A bottom seal 9 is provided on the fixing seat 8. The length direction of the bottom seal 9 is consistent with the width direction of the gate 1. The free end of the bottom seal 9 is tightly fitted and pressed on the rotating end of the gate 1 to prevent liquid from flowing into the right chamber 4 from the bottom of the gate 1.

[0052] In this technical solution, since the gate 1 is a hollow structure, when there is liquid at the bottom of the gate 1, the gate 1 will discharge the liquid, and the liquid at the bottom of the gate 1 forms a buoyancy for the gate 1 as a whole upward, and the buoyancy provides a direct power source for the gate 1 to float; since one end of the gate 1 is hinged to the gate seat 2, specifically, the rotating end of the gate 1 is welded and fixed with a gate main hinge shaft 21, and the gate main hinge shaft 21 is connected to the gate seat 2 in an articulated manner, the buoyancy generated by the liquid on the gate 1 forms a torque relative to the hinge position of the gate 1, so that the gate main hinge shaft 21 rotates around the gate The seat rotates to float the gate 1; since a lower limit block 5 is provided at the bottom of the left chamber 3, the gate 1 abuts against the lower limit block 5 when it rotates to the minimum angle, that is, when there is no liquid in the left chamber 3, the gate 1 is placed on the lower limit block 5, so that a cavity can be formed at the lower part of the gate 1, which is easy to float when there is liquid; since upper limit blocks 6 are provided on the two side walls of the chamber, the gate 1 abuts against the upper limit block 6 when it rotates to the maximum rotation angle, and the upper limit block 6 can limit the extreme position of the gate 1 floating to isolate the liquid in the left chamber 3 from passing through the gate 1.

[0053] Since the gate 1 is symmetrically provided with side seals 7 on both sides, the side seals 7 are tightly fitted and pressed on the side wall of the chamber, and are used to isolate the liquid from the side of the gate 1 from flowing into the right chamber 4. When the waterline is below the side seals 7, the side seals 7 and the side wall of the chamber are tightly fitted, and the two are squeezed to deform the side seals 7. This deformation can isolate the liquids in the left and right chambers of the gate 1 from flowing to each other, thus playing a sealing role. Since the bottom of the chamber is provided with a fixed seat 8, the fixed seat 8 is located near the rotating end of the gate 1, and the fixed seat 8 is provided with a bottom seal 9, the length direction of the bottom seal 9 is consistent with the width direction of the gate 1, and the free end of the bottom seal 9 is tightly fitted and pressed on the rotating end of the gate 1, and is used to isolate the liquid at the bottom of the gate 1 from flowing into the right chamber 4 through the bottom gap. The provision of the side seals 7 and the bottom seals 9 enables the gate 1 to ensure the sealing of the left chamber 3 and the right chamber 4 during movement.

[0054] In summary, the technical solution provides a power source through the volume of liquid displaced by the gate 1 itself. As the liquid level rises, the volume of the displaced liquid increases. The buoyancy overcomes the gate 1's own weight, the friction resistance between the side seal 7 and the side wall, and the friction resistance between the gate 1 and the bottom seal 9. It floats when the fluid level in the left chamber 3 rises and sinks when the fluid level in the left chamber 3 drops. It adaptively adjusts the angle of floating and follows the changes in the liquid level, thereby controlling the liquid level in the left chamber 3 of the gate 1.

[0055] This technical solution is mainly used in places where liquid level needs to be adjusted, such as cave entrances, dam entrances or pipe openings. The liquid level adjustment adopts self-floating adjustment. Under normal circumstances, the equipment itself can complete the adjustment of the fluid liquid level height in the left chamber 3 of the gate 1, and adapt to the change of liquid level. It only relies on the buoyancy of the gate 1 itself to provide a power source, without the need for additional power. The buoyancy of the gate 1 is provided by the height of the liquid level, thereby controlling the rotation of the gate 1, controlling its own floating and sinking, and isolating the liquid level of the left chamber 3 and the right chamber 4 of the gate 1. The opening of the gate 1 can be freely adjusted by relying solely on the buoyancy of the fluid on the gate 1, and the gate 1's own posture can be adjusted and the liquid level can be controlled. No additional power input is required, and the electric gate 1 does not need to be adjusted back and forth, and the equipment combination can be freely matched.

[0056] Embodiment 2:

[0057] This embodiment is optimized based on the above-mentioned embodiment 1.

[0058] Side light plates 10 are provided on both sides of the chamber, and the side seal 7 abuts against the side light plates 10. The contact surface between the side light plates 10 and the side seal 7 is a smooth surface structure, and the smooth surface friction is small when floating, and the friction torque is smaller than the buoyancy torque, and the side seal 7 rotates with the gate 1.

[0059] Embodiment 3:

[0060] This embodiment is optimized based on the above-mentioned embodiment 1.

[0061] The side seal 7 is arranged on the upper part of the side wall of the gate 1. The side seal 7 is connected to the upper part of the gate 1, and a cavity is formed below the side seal 7. When the waterline is below the side seal 7, the relatively larger volume of liquid is displaced, which can provide greater buoyancy.

[0062] Embodiment 4:

[0063] This embodiment is optimized based on the above-mentioned embodiment 3.

[0064] In order to achieve a better side sealing effect, the side seal 7 includes an integrally formed annular sealing portion 7.1 and an extended sealing strip 7.2. The annular sealing portion 7.1 is fixed to the side end of the rotating end of the gate 1, and the extended sealing strip 7.2 extends from the annular sealing portion 7.1 along the length direction of the gate 1, that is, the side seal 7 is in the shape of a number 6. Specifically, the gate 1 and the side seal 7 are connected as a whole by bonding or bolting.

[0065] Embodiment 5:

[0066] This embodiment is optimized based on the above-mentioned embodiment 1.

[0067] The bottom seal 9 and the side seal 7 are both made of soft sealing material, and the free end of the bottom seal 9 is a cylindrical end 9.1. The cylindrical end 9.1 is tangent to the outer circular frame of the rotating end of the gate 1, and maintains a certain deformation and pre-pressure during installation, maintains contact with the gate 1, and isolates the liquid at the bottom of the gate 1 from flowing into the right chamber 4 of the gate 1 through the bottom gap, forming a bottom seal.

[0068] Embodiment 6:

[0069] This embodiment is optimized based on the above-mentioned embodiment 1.

[0070] The free end of the gate 1 is a raised end 1.1, which can provide greater buoyancy.

[0071] Embodiment 7:

[0072] This embodiment is optimized based on the above-mentioned embodiment 1.

[0073] In order to ensure the fluid flowability of the left and right sides of the gate 1 under special conditions, a hydraulic drive mechanism is used to force the floating angle of the gate 1. The force of the hydraulic drive mechanism overcomes the buoyancy of the gate 1, the friction resistance of the side seal 7 and the side light plate 10, and the friction resistance between the gate 1 and the bottom seal 9 to push the gate 1 to a suitable position to maintain the fluid flow between the left and right chambers. It also includes a hydraulic drive mechanism, which includes a hydraulic fixed support 24 and a hydraulic cylinder 11. The hydraulic fixed support 24 is installed at the bottom of the right chamber 4. The hydraulic fixed support 24 is provided with a hydraulic hinge seat 12. The hydraulic hinge seat 12 is provided with an upper limit rod 13 and a lower limit rod 14;

[0074] A top claw 15 is provided on the hydraulic extension rod 19 of the hydraulic cylinder 11, and the top claw 15 is in an eight-shaped shape. The middle part of the hydraulic cylinder 11 is rotatably connected with the hydraulic articulated seat 12. A limit swing rod 16 is provided on the hydraulic cylinder 11, and the limit swing rod 16 is located between the upper limit rod 13 and the lower limit rod 14. The upper limit rod 13 and the lower limit rod 14 respectively limit the swing angle of the limit swing rod 16.

[0075] A gate hinge seat 17 is provided on the back of the gate 1, and a gate hinge shaft 18 is rotatably connected to the gate hinge seat 17. When the hydraulic extension rod 19 of the hydraulic cylinder 11 is extended, the top claw 15 presses on the gate hinge shaft 18 to push the gate 1 toward the left chamber 3.

[0076] The hydraulic cylinder 11 pushes the back of the gate 1. After the gate 1 is pushed to the left extreme position, the hydraulic cylinder 11 opens the pressure-maintaining state, restricting the gate 1 to a fully open state to prevent the gate 1 from being lifted by buoyancy.

[0077] In this technical solution, the hydraulic extension rod 19 has no contact with the gate 1, which reduces the long-term exposure of the hydraulic extension rod 19 and causes rust and wear of the hydraulic extension rod 19 in contact with the fluid, thereby increasing the service life of the equipment.

[0078] The extension and retraction of the hydraulic extension rod 19 of the hydraulic cylinder 11 drives the top claw 15 to extend and retract together. Figure 2 , Figure 3 As shown, the hydraulic cylinder 11 includes a cylinder barrel and a hydraulic extension rod 19. The end of the hydraulic extension rod 19 is screwed to the top claw 15 as a whole. A piston is fixed to the end of the hydraulic extension rod 19 located in the cylinder barrel. The piston separates the internal cavity of the cylinder barrel into left and right chambers, wherein the end of the hydraulic extension rod 19 is a hydraulic rod chamber, and the right side of the piston is a hydraulic rodless chamber. When the hydraulic oil is pumped into the hydraulic oil through the rodless chamber oil inlet, the oil is returned from the rod chamber oil port, and the rodless chamber generates pressure on the right end of the piston. The piston pushes the hydraulic extension rod 19 to extend and drives the top claw 15 to move together. In the retracted state, the hydraulic oil is pumped into the hydraulic oil through the rod chamber oil inlet, and the oil is returned from the rodless chamber oil port. The pressure of the hydraulic rod chamber increases, and pressure is generated at the left end of the piston, pushing the piston to move to the right. The piston drives the hydraulic extension rod 19 and the top claw 15 to move to the right together, completing the retracting action.

[0079] Embodiment 8:

[0080] This embodiment is optimized based on the above-mentioned embodiment 7.

[0081] It also includes a power storage system, which supplies power to the hydraulic control system, and the hydraulic control system controls the movement of the hydraulic cylinder 11.

[0082] In an emergency, the left and right fluids need to be interconnected. At this time, photovoltaic panels are used to collect energy, converting light energy into electrical energy and storing it in the power storage system. The power storage system is only used in an emergency, and it provides energy sources for the control system and the hydraulic power station. The control system controls the operation of various components inside the hydraulic power station. The hydraulic power station supplies hydraulic oil to the hydraulic cylinder 11 through the internal pipeline, and the hydraulic extension rod 19 extends to drive the top claw 15. The top claw 15 presses on the gate hinge shaft 18 to push the gate 1 downward. When the emergency state is lifted, the hydraulic extension rod 19 completes the retraction, returns to the initial position and waits for the next emergency command. The gate 1 relies on its own buoyancy to complete the purpose of controlling the liquid level.

[0083] Photovoltaic panels, city electricity, wind power or other energy supply systems are used to provide equipment with power storage systems. The power storage system can be used normally or as a backup energy source.

[0084] Embodiment 9:

[0085] This embodiment is optimized based on the above-mentioned embodiment 7.

The hydraulic fixed hinge shaft 20 is rotatably connected to the hydraulic articulated seat 12, and the upper limit rod 13 and the lower limit rod 14 are respectively welded to the hydraulic articulated seat 12.

[0087] Embodiment 10:

[0088] This embodiment is optimized based on the above-mentioned embodiment 1.

[0089] like Fig.12 As shown, a mounting hole is provided on the gate seat 2, and a gate main hinge shaft 21 is provided at the rotating end of the gate 1. The gate main hinge shaft 21 is rotatably matched with the mounting hole, and also includes a motor reducer or a hydraulic motor 22 with a clutch. The output shaft of the motor reducer or the hydraulic motor 22 is connected to the gate main hinge shaft 21 through a sprocket chain transmission mechanism, a gear transmission mechanism or a belt transmission mechanism 23. Its function is to directly drive the gate main hinge shaft 21 to rotate, thereby driving the gate 1 to complete the flipping action. The use of a clutch can close the device and start the device in an emergency state, and can also achieve the above functions. Its power source can directly use the mains, wind power or other energy supply systems to the equipment power storage system, and the power storage system is used in emergency or normal use. In emergency use, the power storage system provides an energy source for the equipment control system and the hydraulic power station. In normal use, it is directly connected to the mains, and the mains drives the hydraulic rod in the device to complete the action.

[0090] It should be noted that the lower limit block 5 , the upper limit block 6 , the side light plate 10 , the hydraulic fixed support 24 , the fixed seat 8 , and the gate seat 2 are prefabricated structures, which are completely fixed to the surrounding foundation by anchoring.

[0091] This technical solution is flexible in deployment and can be configured with related auxiliary equipment as needed. By integrating the communication module, the device status can also be remotely controlled or adaptively controlled to improve the overall intelligence level. A variety of methods are used to collect external energy and supply it to the power storage system. The equipment is only used in emergency situations, which is green and environmentally friendly and improves the overall use efficiency of the equipment.

[0092] Working principle description:

[0093] like Figure 4 As shown: the positional relationship between the initial and final states of the moving parts in the device, wherein the dotted line of gate 1 is the initial state and the terminal state of the hydraulic extension rod 19 jacking, the solid line of gate 1 reaches the upper limit position and is hydraulically compressed back to the initial state, and the middle arc arrow line is the movement trajectory of the gate hinge shaft 18 when the gate 1 rotates.

[0094] like Figure 5 Shown: Figure 4 Cross-sectional view at AA, in which the side seals 7 are located on both sides of the gate 1, and the side light plates 10 and the gate 1 clamp the side seals 7 in the middle position. The side seals 7 rotate with the gate 1, and the end seals are formed by the tight fit between the side seals 7 and the side light plates 10; the main hinge shaft 21 of the gate is hinged to the gate seat 2, and the main hinge shaft 21 of the gate passes through the end of the side seal 7 and is hinged to the gate seat 2.

[0095] like Figure 1 As shown: in the initial floating state, the gate 1 and the lower part of the side seal 7 form a cavity, the liquid is discharged, the gate 1 floats up, and the gate 1 rotates around the gate seat 2.

[0096] like Figure 6 As shown: the gate 1 floats to the middle position and is in a free state. According to the liquid level position of the left chamber 3, the gravity moment and the buoyancy moment at the center of the gate main hinge shaft 21 and the extrusion friction force of the side seal 7 and the side light plate 10 form an overall torque balance. When the liquid level decreases, the gate 1 moves downward, and when the liquid level rises, the gate 1 moves upward.

[0097] like Figure 7 As shown: at the final floating position, the upper limit block 6 limits the gate 1, and the liquid in the left chamber 3 is isolated on the left side of the gate 1.

[0098] like Figure 8 As shown: when the liquid level needs to be adjusted urgently, the gate 1 is between the initial and highest positions. The hydraulic extension rod 19 extends, driving the top claw 15 to extend forward. As the overall center of gravity of the top claw 15 and the hydraulic extension rod 19 moves forward, the torque acting on the center of the hydraulic fixed hinge shaft 20 on the left side of the hydraulic cylinder 11 relative to the right side of the hydraulic cylinder 11 gradually increases, and the top claw 15 and the hydraulic extension rod 19 begin to move toward the side close to the gate 1. Because the limit swing rod 16 is fixed on the hydraulic cylinder 11, the limit swing rod 16 hits the lower limit rod 14 when it rotates downward around the hydraulic fixed hinge shaft 20, and the lower limit rod 14 will prevent the hydraulic pressure from further tilting to the left. As the hydraulic extension rod 19 continues to extend forward, the top claw 15 will contact the gate hinge shaft 18 on the trajectory of the top claw 15.

[0099] like Fig.13 As shown: a partial enlarged view of the vicinity of the hydraulic articulated seat 12, the limit swing rod 16, the hydraulic cylinder 11 and the hydraulic fixed hinge shaft 20 are fixed as a whole, and rotate around the hydraulic articulated seat 12. The limit swing rod 16 is welded to the outer wall of the hydraulic cylinder 11. When the hydraulic cylinder 11 swings, it drives the limit swing rod 16 to swing. The limit swing rod 16 can only swing between the lower limit rod 14 and the upper limit rod 13. The corresponding swing angles of the hydraulic cylinder 11, the hydraulic extension rod 19 and the top claw 15 are limited within a certain range.

[0100] like Fig. 9As shown: when an emergency occurs, the liquid in the left chamber 3 needs to flow to the right chamber 4, and the rodless chamber of the hydraulic cylinder 11 is filled with oil to push the hydraulic extension rod 19 to extend. The hydraulic extension rod 19 can only swing to a limited angle. The swing amount of this angle needs to ensure that the top claw 15 contacts any point on the gate hinge shaft 18. Figure 8 The simulated top claw 15 is shown at the moment of contact with the gate hinge shaft 18.

[0101] like Fig. 9 As shown: the middle of the top claw 15 has a groove 15.1, which is fully matched with the gate hinge shaft 18. The thrust of the hydraulic extension rod 19 is much greater than the central moment of the gate 1 buoyancy relative to the gate main hinge shaft 21. The hydraulic cylinder 11 pushes the gate 1 downward together through the cooperation between the top claw 15 and the gate hinge shaft 18.

[0102] like Fig. 9 As shown: when the gate 1 is pushed downward, the liquid in the left chamber 3 flows to the right chamber 4.

[0103] like Fig.10 As shown: the gate 1 is pushed downward to the bottom limit position, the left chamber 3 and the right chamber 4 of the gate 1 are completely connected, and the liquid in the left chamber 3 and the right chamber 4 flows freely.

[0104] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
