TECHNICAL FIELD

[0001] The utility model relates to gate technical field, concretely relates to a self-floating gate. BACKGROUND

[0002] Ordinary gate cannot realize real-time regulation opening degree, needs to switch back and forth electric control system adjustment, ordinary gate adopts hydraulic cylinder power, and hydraulic extension rod is easy to expose and cause corrosion, wear and tear service life short, poor economy, ordinary gate needs personnel to carry back and forth operating tool, and the labor intensity is big. CONTENT OF UTILITY MODEL

[0003] The utility model aims at providing a self-floating gate to solve at least one of the above problems in the prior art.

[0004] In order to realize the above-mentioned purpose, the utility model adopts the following technical scheme:

[0005] A self-floating gate, comprising a chamber, a gate seat and a gate, 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 on the left side of the gate is a left chamber, and the chamber on the right side of the gate is a right chamber, a lower limit block is arranged at the bottom of the left chamber, and the gate abuts against the lower limit block when the gate rotates to the minimum angle, upper limit blocks are arranged on the two side walls of the chamber, and the gate abuts against the upper limit blocks when the gate rotates to the maximum rotation angle.

[0006] Symmetrical side sealing elements are arranged on the two sides of the gate, the side sealing elements are tightly fitted and pressed on the side walls of the chamber, and are used to isolate the liquid from flowing into the right chamber from the side of the gate, a fixing seat is arranged at the bottom of the chamber, the fixing seat is located close to the rotating end of the gate, a bottom sealing element is arranged on the fixing seat, the length direction of the bottom sealing element is consistent with the width direction of the gate, and the free end of the bottom sealing element is tightly fitted and pressed on the rotating end of the gate, and is used to isolate the liquid from flowing into the right chamber from the bottom of the gate.

[0007] The gate is a hollow structure, when the gate bottom has liquid, the gate will push away the liquid, the liquid at the gate bottom forms a whole upward floating force on the gate, the floating force provides a direct power source for the gate to float up, because one end of the gate is hinged to the gate seat, the floating force of the liquid on the gate forms a moment relative to the hinge position of the gate, so that the gate rotates around the gate seat and floats up, because the bottom of the left chamber is provided with a lower limit block, when the gate rotates to the minimum angle and abuts against the lower limit block, that is, when the left chamber has no liquid, the gate rests on the lower limit block, so that the lower part of the gate forms a cavity, and the gate is easy to float up when there is liquid, because the two side walls of the chamber are provided with upper limit blocks, when the gate rotates to the maximum rotation angle and abuts against the upper limit blocks, the upper limit blocks can limit the limit position of the gate to float up, so as to isolate the liquid in the left chamber from passing through the gate.

[0008] Because the two sides of the gate are symmetrically provided with side sealing members, the side sealing members are tightly fitted and pressed on the side walls of the chamber, and are used to isolate the liquid from flowing into the right chamber from the side of the gate, when the water line is below the side sealing member, because the side sealing member and the side wall of the chamber are tightly fitted, the two sides extrude the side sealing member to deform, and the deformation amount can isolate the liquid in the left and right chambers from flowing into each other, and plays a sealing role. Because the bottom of the chamber is provided with a fixed seat located close to the rotating end of the gate, the fixed seat is provided with a bottom sealing member, the length direction of the bottom sealing member is consistent with the width direction of the gate, and the free end of the bottom sealing member is tightly fitted and pressed on the rotating end of the gate, and is used to isolate the liquid in the bottom of the gate from flowing into the right chamber through the bottom gap. The arrangement of the side sealing member and the bottom sealing member can ensure the sealing performance of the left and right chambers during the movement of the gate.

[0009] In summary, the technical scheme provides a power source by pushing away the volume of liquid by the gate itself, as the liquid level rises, the volume of the pushed away liquid increases, the floating force overcomes the self-weight of the gate, the friction resistance between the side sealing member and the side wall, and the friction resistance between the gate and the bottom sealing member, and the gate floats up when the fluid level in the left chamber rises, and sinks when the fluid level in the left chamber falls, and the angle of the gate is adaptively adjusted and floated up according to the change of the liquid level, so as to control the liquid level in the left chamber of the gate.

[0010] The technical scheme is mainly applied to situations such as openings, dam openings or pipe openings that need to adjust the liquid level, and the liquid level is adjusted by self-floating. Under normal circumstances, the equipment itself can complete the adjustment of the liquid level height of the fluid in the left chamber of the gate, adapt to the change of the liquid level, and only rely on the floating force of the gate itself to provide a power source, without the need for additional power, the floating force of the gate is provided by the height of the liquid level, so as to control the rotation of the gate, control the floating and sinking of the gate itself, and isolate the liquid levels in the left and right chambers of the gate. Only the floating force of the fluid on the gate can freely adjust the opening degree of the gate, and the attitude of the gate is adjusted and the liquid level is controlled, without the need for additional power input, without the need for an electric gate to adjust back and forth, and the equipment can be freely combined.

[0011] Further, the two sides of the chamber are provided with side light panels, and the side seal abuts against the side light panels. The contact surface between the side light panel and the side seal is a light surface structure. When floating, the light surface has small friction and the friction torque is smaller than the buoyancy torque, so the side seal rotates with the gate.

[0012] Further, the side seal is arranged at the upper part of the side wall of the gate. The side seal is connected to the upper part of the gate, and a cavity is formed below the side seal. When the water line is below the side seal, the relative liquid volume is larger, and a larger buoyancy can be provided.

[0013] Further, in order to achieve better side sealing effect, the side seal comprises an integral annular sealing part and an extended sealing strip. The annular sealing part is fixed to the side end of the rotating end of the gate, and the extended sealing strip extends from the annular sealing part along the length direction of the gate, that is, the side seal has a shape of number 6. Specifically, the gate and the side seal are integrally connected by adhesion or bolts.

[0014] Further, 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. When installed, a certain deformation and pre-pressure are maintained to keep contact with the gate and to isolate the liquid in the bottom part of the gate from flowing into the right chamber of the gate through the bottom gap, thereby forming a bottom seal.

[0015] Further, the free end of the gate is a protruding end, which can provide a larger buoyancy.

[0016] Further, in order to ensure the liquid flow between the left and right sides of the gate in special conditions, a hydraulic driving mechanism is used to force the floating angle of the gate. The force of the hydraulic driving mechanism overcomes the buoyancy of the gate, the friction resistance between the side seal and the side light panel, and the friction resistance between the gate and the bottom seal, so as to push the gate to the appropriate position and maintain the fluid flow between the left and right chambers. The hydraulic driving mechanism comprises a hydraulic fixed support and a hydraulic cylinder. The hydraulic fixed support is installed at the bottom of the right chamber, and the hydraulic fixed support is provided with a hydraulic hinged seat, an upper limit rod and a lower limit rod.

[0017] The hydraulic cylinder is provided with a top claw, which is in the shape of a split, and the middle part of the hydraulic cylinder is rotatably connected to the hydraulic hinged seat. The hydraulic cylinder is provided with a limiting swing rod, which is located between the upper limit rod and the lower limit rod. The upper limit rod and the lower limit rod limit the swing angle of the limiting swing rod.

[0018] The back of the gate is provided with a gate hinge seat, and a gate hinge shaft is rotationally connected to the gate hinge seat; when the hydraulic cylinder is in the extended state, the top claw is pressed on the gate hinge shaft to push the gate towards the left chamber.

[0019] The hydraulic cylinder pushes the back of the gate, and after the gate is pushed to the left limit position, the hydraulic cylinder opens the pressure maintaining state, limits the gate in the fully open state, and prevents the gate from being lifted by the buoyancy.

[0020] In the technical solution, the hydraulic extension rod does not contact the gate, reducing the corrosion and wear caused by the long-term exposure of the hydraulic extension rod to the fluid, and improving the service life of the equipment.

[0021] Further, the power storage system is also included, which supplies power to the hydraulic control system, and the hydraulic control system controls the action of the hydraulic cylinder.

[0022] The common gate needs to be connected to the mains to adjust the opening degree, and the use is limited in the field. In the technical solution, when the emergency state occurs, the left and right fluid needs to be connected to each other, at which time the photovoltaic panel is used to collect energy, and the light energy is converted into electrical energy and stored in the power storage system. The power storage system is only used in emergency state, which provides energy source for the control system and the hydraulic power station. The control system controls the work of each component in the hydraulic power station, and the hydraulic power station supplies hydraulic oil to the hydraulic cylinder through the internal pipeline, the hydraulic extension rod is extended to drive the top claw, the top claw is pressed on the gate hinge shaft, and the gate is pushed downward. When the emergency state is removed, the hydraulic extension rod is retracted to the initial position to wait for the next emergency command, and the gate relies on its own buoyancy to complete the control of the liquid level.

[0023] The photovoltaic panel, mains, wind power or other energy supply system is used to store power in the equipment power storage system, and the power storage system can be used normally or as a backup energy source.

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

[0025] Further, the gate seat is provided with a mounting hole, the rotating end of the gate is provided with a gate main hinge shaft, the gate main hinge shaft is in rotating fit with the mounting hole, and the gate main hinge shaft is in transmission connection with the output shaft of the motor speed reducer or the hydraulic motor through a chain and sprocket transmission mechanism, a gear transmission mechanism or a belt transmission mechanism.

[0026] The technical scheme has the advantages that: the gate is a hollow structure, when there is liquid at the bottom of the gate, the liquid is pushed away by the gate, and the liquid forms an upward buoyancy force at the bottom of the gate, which provides a direct power source for the floating of the gate; one end of the gate is hinged to the gate seat, and the buoyancy force of the liquid relative to the hinge position of the gate forms a moment, so that the gate rotates around the gate seat and floats up; the bottom of the left chamber is provided with a lower limit block, and the gate abuts against the lower limit block when the gate 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 is formed at the bottom of the gate, and the gate is easy to float up when there is liquid; the upper limit block is arranged on the two side walls of the chamber, and the gate abuts against the upper limit block when the gate rotates to the maximum rotation angle, so that the upper limit block limits the limit position of the floating of the gate, and the liquid in the left chamber is isolated from the gate.

[0027] The two sides of the gate are symmetrically provided with side sealing members, the side sealing members are tightly fitted and pressed on the side walls of the chamber, and the side sealing members are used to isolate the liquid from flowing into the right chamber from the side of the gate; when the water line is below the side sealing member, the side sealing member is deformed by extrusion due to the tight fit between the side sealing member and the side wall of the chamber, and the deformation amount can isolate the liquid in the left and right chambers from flowing into each other, thereby playing a sealing role. The bottom of the chamber is provided with a fixing seat located close to the rotating end of the gate, the fixing seat is provided with a bottom sealing member, the length direction of the bottom sealing member is consistent with the width direction of the gate, and the free end of the bottom sealing member is tightly fitted and pressed on the rotating end of the gate, so as to isolate the liquid at the bottom of the gate from flowing into the right chamber through the bottom gap. The side sealing member and the bottom sealing member can ensure the sealing of the left and right chambers during the movement of the gate.

[0028] In summary, the technical scheme provides a power source by the volume of liquid removed by the gate itself, as the liquid level rises, the volume of liquid removed increases, the buoyancy overcomes the weight of the gate, the friction resistance between the side sealing member and the side wall, and the friction resistance between the gate and the bottom sealing member, and the gate floats up when the fluid level in the left chamber rises, and sinks when the fluid level in the left chamber falls, and the angle of the gate is adaptively adjusted and floated according to the change of the fluid level, so as to control the fluid level in the left chamber of the gate.

[0029] The technical scheme is mainly applied to a situation that needs to adjust the liquid level, such as a hole, a dam or a pipe, and the liquid level is adjusted by self-floating. Under normal circumstances, the equipment itself can complete the adjustment of the fluid level height in the left chamber of the gate, and adaptively changes the liquid level, and only the buoyancy of the gate itself provides a power source, without additional power, and the buoyancy of the gate is provided by the height of the liquid level, so as to control the rotation of the gate, control the floating and sinking of the gate itself, and isolate the liquid levels in the left chamber and the right chamber of the gate. The gate opening degree is freely adjusted only by the buoyancy of the fluid on the gate, the posture of the gate is adjusted in real time, and the liquid level is controlled, without additional power input, without an electric gate to adjust back and forth, and the equipment can be freely combined.

DETAILED DESCRIPTION

[0048] In order to more clearly illustrate the technical scheme in the embodiments of the utility model or prior art, the utility model will be briefly introduced in combination with the drawings and the description of the embodiments or prior art, and obviously, the following description of the drawing structure is only some embodiments of the utility model, and for those skilled in the art, other drawings can be obtained according to these drawings without creative labor.It needs to be explained that the description of these embodiment modes is used to help understanding the utility model, and does not constitute the limitation to the utility model.

[0049] Embodiment 1:

[0050] As Figures 1-17The embodiment shown provides a self-floating gate, which comprises a chamber, a gate base 2 and a gate 1. The gate base 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 base 2. The chamber on the left side of the gate 1 is a left chamber 3. The chamber on the right side of the gate 1 is a right chamber 4. The bottom of the left chamber 3 is provided with a lower limiting block 5. The gate 1 abuts against the lower limiting block 5 when the gate 1 rotates to the minimum angle. The two side walls of the chamber are provided with upper limiting blocks 6. The gate 1 abuts against the upper limiting blocks 6 when the gate 1 rotates to the maximum rotating angle.

[0051] The two sides of the gate 1 are symmetrically provided with side sealing members 7, which are tightly pressed on the side walls of the chamber, so as to prevent liquid from flowing into the right chamber 4 from the side of the gate 1. The bottom of the chamber is provided with a fixing seat 8, which is located close to the rotating end of the gate 1. The fixing seat 8 is provided with a bottom sealing member 9, the length direction of which is consistent with the width direction of the gate 1. The free end of the bottom sealing member 9 is tightly pressed on the rotating end of the gate 1, so as to prevent liquid from flowing into the right chamber 4 from the bottom of the gate 1.

[0052] According to the technical scheme, when the bottom of the gate 1 is filled with liquid, the liquid is pushed away by the gate 1. The liquid forms an upward floating force on the gate 1, which provides a direct power source for the floating of the gate 1. One end of the gate 1 is hinged to the gate base 2. Specifically, the rotating end of the gate 1 is welded with a gate main hinge shaft 21, which is connected to the gate base 2 in a hinged manner. The floating force of the liquid on the gate 1 forms a moment relative to the hinged position of the gate 1, so that the gate main hinge shaft 21 rotates around the gate base, and the gate 1 is floated up. The bottom of the left chamber 3 is provided with the lower limiting block 5. When the gate 1 rotates to the minimum angle, the gate 1 abuts against the lower limiting block 5. That is, when the left chamber 3 is in a liquid-free state, the gate 1 is placed on the lower limiting block 5, so that a cavity is formed at the lower part of the gate 1, and the gate 1 is easy to float up when filled with liquid. The two side walls of the chamber are provided with the upper limiting blocks 6. When the gate 1 rotates to the maximum rotating angle, the gate 1 abuts against the upper limiting blocks 6. The upper limiting blocks 6 can limit the limit position of the floating of the gate 1, so as to prevent the liquid in the left chamber 3 from passing through the gate 1.

[0053] Due to the two sides of the gate 1 are symmetrically provided with the side seal 7, the side seal 7 is tightly fitted and pressed on the side wall of the chamber, and is used to isolate the liquid from flowing into the right chamber 4 from the side of the gate 1. When the water line is below the side seal 7, due to the tight fit between the side seal 7 and the side wall of the chamber, the side seal 7 is deformed by extrusion, and the deformation amount can isolate the liquid in the left chamber 3 and the right chamber 4 from flowing into each other, and plays a sealing role. Due to the bottom of the chamber is provided with the fixed seat 8, the fixed seat 8 is located close to the rotating end of the gate 1, the bottom seal 9 is arranged on the fixed seat 8, 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 arrangement of the side seal 7 and the bottom seal 9 can ensure the sealing performance of the left chamber 3 and the right chamber 4 during the movement of the gate 1.

[0054] In summary, the technical scheme provides a power source by the volume of the liquid displaced by the gate 1 itself, and as the liquid level rises, the volume of the liquid displaced increases. The buoyancy overcomes the weight of the gate 1, the frictional resistance between the side seal 7 and the side wall, and the frictional resistance between the gate 1 and the bottom seal 9. When the fluid level in the left chamber 3 rises, the gate 1 floats up. When the fluid level in the left chamber 3 falls, the gate 1 sinks down. The gate 1 adaptively adjusts and floats up according to the change of the liquid level, thereby controlling the liquid level in the left chamber 3 of the gate 1.

[0055] The technical scheme is mainly applied to situations such as openings, dam openings or pipe openings that need to adjust the liquid level. The liquid level is adjusted by self-floating adjustment. Under normal circumstances, the equipment itself can complete the adjustment of the fluid level height in the left chamber 3 of the gate 1, adaptively changes the liquid level, and only relies on the buoyancy of the gate 1 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 the floating and sinking of the gate 1, and isolating the liquid levels in the left chamber 3 and the right chamber 4 of the gate 1. Only the buoyancy of the fluid on the gate 1 can freely adjust the opening degree of the gate 1, follow the adjustment of the posture of the gate 1 and control the liquid level, without the need for additional power input, without the need for an electric gate 1 to adjust back and forth, and can be freely combined with equipment.

[0056] Embodiment 2:

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

[0058] The two sides of the chamber are provided with side light plates 10, 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 light surface structure. When floating up, the light surface has small friction 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 an optimization based on the above embodiment 1.

[0061] The side seal 7 is located 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 water line is below the side seal 7, the volume of liquid displaced is relatively larger, which can provide greater buoyancy.

[0062] Example 4:

[0063] This embodiment is an optimization based on the above embodiment 3.

[0064] To achieve a better side sealing effect, the side sealing element 7 includes an integrally formed annular sealing part 7.1 and an extended sealing strip 7.2. The annular sealing part 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 part 7.1 along the length direction of the gate 1. That is, the side sealing element 7 is in the shape of the number 6. Specifically, the gate 1 and the side sealing element 7 are connected as one piece by adhesive or bolt.

[0065] Example 5:

[0066] This embodiment is an optimization based on the above embodiment 1.

[0067] Both the bottom seal 9 and the side seal 7 are made of soft sealing material. 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. During installation, it maintains a certain deformation and pre-pressure to keep in contact with the gate 1 and prevent liquid at the bottom of the gate 1 from flowing into the right side chamber 4 of the gate 1 through the bottom gap, thus forming a bottom seal.

[0068] Example 6:

[0069] This embodiment is an optimization based on the above embodiment 1.

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

[0071] Example 7:

[0072] This embodiment is an optimization based on the above embodiment 1.

[0073] To ensure fluid flow on both sides of gate 1 under special conditions, a hydraulic drive mechanism is used to force the gate 1 to float at a certain angle. The force of this hydraulic drive mechanism overcomes the buoyancy of gate 1, the frictional resistance between the side seal 7 and the side smooth plate 10, and the frictional resistance between gate 1 and the bottom seal 9, pushing gate 1 to a suitable position to maintain fluid flow between the left and right chambers. The system also includes a hydraulic drive mechanism comprising 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, and a hydraulic hinge seat 12 is provided on the hydraulic fixed support 24. The hydraulic hinge seat 12 is provided with an upper limit rod 13 and a lower limit rod 14.

[0074] The hydraulic cylinder 11 has a top claw 15 on its hydraulic extension rod 19. The top claw 15 is V-shaped. The middle part of the hydraulic cylinder 11 is rotatably connected to the hydraulic hinge seat 12. The hydraulic cylinder 11 has a limiting swing rod 16. The limiting 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 limiting swing rod 16.

[0075] The back of the gate 1 is provided with a gate hinge seat 17, 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, pushing the gate 1 to the left limit position. Then, the hydraulic cylinder 11 enters the pressure holding state, restricting the gate 1 to the fully open state to prevent the gate 1 from being lifted by buoyancy.

[0077] In this technical solution, the hydraulic extension rod 19 does not contact the gate 1, which reduces the long-term exposure of the hydraulic extension rod 19 to fluid, thus preventing corrosion and wear and improving the service life of the equipment.

[0078] The extension and retraction of the hydraulic cylinder 11 and hydraulic extension rod 19 cause the top claw 15 to extend and retract together. Specifically, as shown... Figure 2 , Figure 3As 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 integrally with the top claw 15. A piston is fixed to the end of the hydraulic extension rod 19 located inside the cylinder barrel. The piston isolates the internal cavity of the cylinder barrel into left and right chambers, with the end of the hydraulic extension rod 19 being the hydraulic rod-side chamber and the right side of the piston being the hydraulic rodless chamber. When hydraulic oil is pumped into the rodless chamber through the inlet port and returned from the rod-side chamber, the rodless chamber generates pressure on the right end of the piston, causing the piston to push the hydraulic extension rod 19 out and move the top claw 15 together. In the retracted state, hydraulic oil is pumped into the rod-side chamber through the inlet port and returned from the rodless chamber, increasing the pressure in the hydraulic rod-side chamber. This generates pressure on the left end of the piston, pushing the piston to the right. The piston then moves the hydraulic extension rod 19 and the top claw 15 together to the right, completing the retraction action.

[0079] Example 8:

[0080] This embodiment is an optimization based on the above embodiment 7.

[0081] It also includes an energy 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 fluid on both sides needs to be interconnected. At this time, photovoltaic panels collect energy, converting light energy into electrical energy and storing it in an energy storage system. This energy storage system is only used in emergency situations, providing energy to the control system and hydraulic power station. The control system controls the operation of various components within the hydraulic power station. The hydraulic power station supplies hydraulic oil to the hydraulic cylinder 11 through internal pipelines. The hydraulic extension rod 19 extends, driving the pawl 15, which presses against the gate hinge 18, pushing the gate 1 downwards. Once the emergency is over, the hydraulic extension rod 19 retracts, returning to its initial position to await the next emergency command. The gate 1 then relies on its own buoyancy to control the liquid level again.

[0083] The energy storage system of the equipment can be powered by photovoltaic panels, mains power, wind power or other energy supply systems. The energy storage system can be used normally or as a backup energy source.

[0084] Example 9:

[0085] This embodiment is an optimization based on the above embodiment 7.

[0086] To better achieve the fixed connection of the corresponding components, the hydraulic hinge seat 12 is fixedly installed on the upper end of the hydraulic fixed support 24 by bolts, the gate hinge seat 17 is welded or bolted to the back of the gate 1, the hydraulic cylinder 11 is fixedly provided with a hydraulic fixed hinge shaft 20 in the middle, the hydraulic fixed hinge shaft 20 is rotatably connected to the hydraulic hinge seat 12, and the upper limit rod 13 and the lower limit rod 14 are respectively welded to the hydraulic hinge seat 12.

[0087] Example 10:

[0088] This embodiment is an optimization based on the above embodiment 1.

[0089] like Figure 12 As shown, the gate seat 2 has mounting holes, and the rotating end of the gate 1 has a gate main hinge shaft 21. The gate main hinge shaft 21 is rotatably engaged with the mounting holes. It also includes a motor reducer or hydraulic motor 22 with a clutch. The output shaft of the motor reducer or hydraulic motor 22 is connected to the gate main hinge shaft 21 via a sprocket and chain transmission mechanism, gear transmission mechanism, or 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 clutch allows the equipment to be engaged and started in an emergency, and can also achieve the above functions. Its power source can be directly supplied to the equipment's energy storage system from mains power, wind power, or other energy supply systems. The energy storage system is used for emergency or normal operation. In emergency use, the energy storage system provides energy to the equipment control system and hydraulic power station. In normal operation, it is directly connected to mains power, and the mains power drives the hydraulic rods in the equipment to complete the action.

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

[0091] This technical solution offers flexible deployment, allowing for the configuration of relevant auxiliary equipment as needed. By integrating a communication module, it also enables remote or adaptive control of the equipment status, enhancing its overall intelligence. It utilizes multiple methods to collect external energy and supply it to the energy storage system, ensuring the equipment is used only in emergency situations, making it environmentally friendly and improving overall equipment efficiency.

[0092] Working principle explanation:

[0093] like Figure 4 The diagram shows the positional relationships of each moving part in the device in its initial and final states. The dashed line of gate 1 represents the initial state and the final state of the hydraulic extension rod 19 being lifted. The solid line of gate 1 represents the upper limit position and the hydraulic compression back to the initial state. The arc-shaped arrow in the middle represents the movement trajectory of the gate hinge shaft 18 when gate 1 rotates.

[0094] like Figure 5 As shown: Figure 4 The cross-sectional view at point AA shows that the side seal 7 is located on both sides of the gate 1. The side plate 10 and the gate 1 clamp the side seal 7 in the middle position. The side seal 7 rotates with the gate 1 and forms an end seal by tightly fitting the side seal 7 with the side plate 10. The gate main hinge shaft 21 is hinged to the gate seat 2. The gate main hinge shaft 21 passes through the end of the side seal 7 and is hinged to the gate seat 2.

[0095] like Figure 1As 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: Gate 1 floats to the middle position, in a free state. Based on the liquid level in the left chamber 3, the gravitational torque and buoyancy torque at the center of the gate's main hinge shaft 21, as well as the extrusion friction between the side seal 7 and the side smooth plate 10, form an overall torque balance. When the liquid level decreases, gate 1 moves downward; when the liquid level increases, gate 1 moves upward.

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

[0098] like Figure 8 As shown: When an emergency adjustment of the liquid level is required, gate 1 is between its initial and highest positions. The hydraulic extension rod 19 extends, causing the top claw 15 to extend forward. Due to the forward shift of the overall center of gravity of the top claw 15 and the hydraulic extension rod 19, the torque acting on the center of the hydraulic fixed hinge shaft 20 relative to the right side of the hydraulic cylinder 11 gradually increases. The top claw 15 and the hydraulic extension rod 19 begin to move towards the side closer to gate 1. Because the limiting swing rod 16 is fixed to the hydraulic cylinder 11, when the limiting swing rod 16 rotates downward around the hydraulic fixed hinge shaft 20, it encounters the lower limit rod 14, which 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 along its movement trajectory.

[0099] like Figure 13 The image shows a partial enlarged view near the hydraulic hinge seat 12. The limiting swing rod 16, hydraulic cylinder 11, and hydraulic fixed hinge shaft 20 are fixed together and rotate around the hydraulic hinge seat 12. The limiting swing rod 16 is welded to the outside of the cylinder wall of the hydraulic cylinder 11. When the hydraulic cylinder 11 swings, it drives the limiting swing rod 16 to swing. The limiting swing rod 16 can only swing between the lower limiting rod 14 and the upper limiting rod 13. The swing angles of the corresponding hydraulic cylinder 11, hydraulic extension rod 19, and top claw 15 are limited to a certain range.

[0100] like Figure 9 As shown: In an emergency, the liquid in the left chamber 3 needs to flow to the right chamber 4. Oil enters the rodless chamber of the hydraulic cylinder 11, pushing the hydraulic extension rod 19 to extend. The hydraulic extension rod 19 can only swing at a limited angle; this swing angle must ensure that the top claw 15 contacts any point on the gate hinge shaft 18. Figure 8 The image shows the moment when the top claw 15 just makes contact with the gate hinge shaft 18.

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

[0102] like Figure 9 As shown: During the downward movement of the gate 1, the liquid in the left chamber 3 flows to the right chamber 4.

[0103] like Figure 10 As shown: When the gate 1 is pushed down 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 can flow freely.

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