Description

Technical Field

[0001] The present invention belongs to the fields of farmland water conservancy, municipal administration, transportation, mechanical equipment and fluid, and is particularly a two-way dual-control flap door system. Two-way refers to controlling a flap door to achieve two flow states: water diversion (water diversion from external water to internal river) or water drainage (water drainage from internal river to external river); dual control refers to the flap door having the function of being closed and openable under high pressure of internal water. Background Art

[0002] Gates and opening and closing equipment are control devices installed on various flow passages of flow structures and are important components of flow structures. The gates can be opened or closed to adjust the flow and water level to achieve the purpose of flood control, irrigation, power generation, navigation, wood passing, sand, ice, and drift. Common gate shapes include plane, arc, fan, etc.

[0003] The plane gate has a simple structure and is easy and reliable to operate. It is the most commonly used gate in hydraulic structures. According to its shape, it is divided into flat plate and beam format gates; the panel can be made into a flat or curved form. According to its different movement methods, there are vertical lifting type, horizontal (push) pull type, rotating type, floating box type, lifting and horizontal type plane gates, etc. The horizontal pull type plane gate can move horizontally along the track and is only suitable for operation under static water conditions. The rotating plane gate is divided into horizontal axis rotation (flap gate, flap gate and flap gate) and vertical axis rotation (straight gate and miter gate). The floating box type plane gate can only be operated under static water conditions and is generally used as a maintenance gate.

[0004] In water conservancy and hydropower projects, the main requirements for opening and closing equipment are: safe and reliable operation, high efficiency, simple structure, light weight, low cost and maintenance cost, easy operation, neat appearance, small size, small footprint, etc. When selecting opening and closing equipment, the following factors should be considered: gate type, size and operation status, number of orifices, opening and closing force, sometimes also consider holding force, opening and closing stroke, opening and closing speed, number and spacing of hanging points, power conditions, space size and building conditions of the installation site. The type of gate determines the structural scheme of the gate chamber, the opening and closing method, the flow state, the management and operation facilities and personnel configuration, the traffic on the gate and the foundation treatment plan, which has a significant impact on the construction cost and management and operation.

[0005] According to the Bulletin of the First National Water Resources Census, the standard time point of the census was December 31, 2011, and the census period was 2011. There were 268,476 sluice gates with a flow rate of 1 cubic meter per second or more, and 2,685 rubber dams.

[0006] According to the statistics of Zhejiang Provincial Water Resources Department in 2017 (June 2018), there are 13,221 sluice gates above designated size, including 18 large sluice gates, 344 medium sluice gates, and 12,859 small sluice gates. Small and medium sluice gates account for more than 99.9%. The single-hole gate width is less than or equal to 6m, accounting for 95.5%, less than or equal to 5m, accounting for 92.7%, and 2 to 3m, accounting for 65.5%. Therefore, the study of gates with a single-hole net width of less than or equal to 6m is universal and general.

[0007] The situation of the prior art is as follows:

[0008] 1. Pivot rotation. Typical applications include horizontal axis rotation (flap doors, flap doors and clapping doors), flap doors are divided into upper flaps and small flaps; vertical axis rotation (straight door and miter door); arc (fan) gate.

[0009] 2. Straight up and down (Z-axis motion trajectory). Typical applications include fixed wheels, slides, sprockets, string wheels, and reverse hooks; special ones include lifting and horizontal plane gates, and the motion trajectory is vertical lifting-rotation-translation.

[0010] 3. Push-pull (X-axis, vertical water flow direction movement track), typical application is horizontal pull gate. It occupies more opening and closing walking track space.

[0011] 4. The Y-axis (movement trajectory along the direction of water flow) is rarely used, and the typical application is the floating box gate.

[0012] 5. Translation in the Y-axis direction + rotation of the fulcrum, no application yet.

[0013] The gate movement trajectory is mostly pivot rotation, straight up and down (Z-axis movement trajectory) or push and pull (X-axis, vertical water flow direction movement trajectory), which occupies more opening and closing walking trajectory space; the Y-axis (movement trajectory along the water flow direction) is rarely used, and the typical application is the floating box type flat gate. There is no relevant research and application of the gate whose operation trajectory is Y-axis translation + pivot rotation.

[0014] Generally, gates are made of steel and reinforced concrete, which have a large deadweight and require larger opening and closing equipment. With the development and widespread application of composite materials in large aircraft and domestic wind turbines (impeller diameter 126m, blade length 61.5m, single blade mass 18 tons) in the aviation field, the time is ripe for the use of composite gates. At present, composite gates for small and medium-sized water gates are not widely used.

[0015] The double-control flap door overcomes the problem that the traditional flap door can only operate in one direction (i.e., open), and has the dual control function of being still closed and openable under high liquid level. The double-control flap door cover is originally closed. Under this premise, through the control system, according to the locking relationship between the flap door cover and the flap door seat, under the high pressure state inside the flap door, the flap door cover is still closed and can be opened, which has two control functions. In terms of flow control, the double-control flap door can only realize the one-way drainage or water diversion function, and the flap door opening cannot be controlled. Summary of the invention

[0016] In order to overcome the deficiency of the existing flap door that it cannot simultaneously have the bidirectional functions of controlling drainage and water diversion, the present invention provides a bidirectional double-control flap door system that simultaneously has the bidirectional functions of controlling drainage and water diversion.

[0017] The technical solution adopted by the present invention to solve the technical problem is:

[0018] A two-way system for a double-controlled flap door, the system comprising a double-controlled flap door system, a flap door translation system and a flap door translation limit system, the double-controlled flap door system comprising a double-controlled flap door, a flap door support, a flap door support and a flap door fixed-axis rotation locking device for driving the double-controlled flap door to rotate, the double-controlled flap door is located on the flap door support, the upper end of the double-controlled flap door is mounted on the flap door support, and the double-controlled flap door is connected to the flap door fixed-axis rotation locking device;

[0019] The flap door translation system includes a driving device, a driving travel support track, a driving limit device and a translation link beam; the flap door support is installed on the translation link beam, and the two ends of the translation link beam are respectively slidably connected to the driving travel support track, and the translation link beam is connected to the driving device for driving its movement and the driving limit device for limiting the position; the left and right extreme positions on the driving travel support track correspond to the flap door positions of the two liquid flow channels where the double-control flap door system is located;

[0020] The flap door translation limiting system comprises a limiting device, and the limiting device is located between two liquid flow channels.

[0021] Furthermore, the flap door fixed axis rotation locking device comprises a locking hole, a locking pin, a reinforced honeycomb plate and a fixed axis anti-vibration stop assembly; the locking hole and the reinforced honeycomb plate are arranged on the flap door; the locking pin is arranged on the flow channel pier and is a telescopic device, and the locking pin cooperates with the locking hole to achieve anti-vibration and locking when the fixed axis rotates;

[0022] The fixed axis anti-vibration stop-at-anytime component includes a driving device and a damping device. When the damping device is a slider, the stop-at-anytime component is connected to a flap door; when the damping device is an airbag, the stop-at-anytime component can be connected to a flap door or a flow channel pier; under the action of the driving device, the damping device achieves vibration prevention and locking when the fixed axis rotates through the damping effect with the flow channel pier or the flap door. Preferably, the fixed axis anti-vibration stop-at-anytime component is an airbag damping method or a slider damping method.

[0023] Furthermore, the position limiting device is a position limiting float, which includes a float and a slide rod. The float is suspended at a certain high position of the flow channel pier cavity by the buoyancy, the cavity is connected to the flow channel liquid, and the rise and fall of the float is automatically coordinated with the buoyancy of the liquid level. The slide rod is connected to the float and exposed outside the flow channel pier. Of course, other solutions are also possible.

[0024] Furthermore, the flap door translation limit system also includes a finger limit component, and the finger limit component is distributed between the flap door and the limit device, and the finger limit component matches the two sides of the dual-control flap door.

[0025] Preferably, the finger limit assembly includes a driving device and a telescopic device. The finger limit assembly is fixed in the flow channel pier. The driving device is hydraulic, mechanical, pneumatic or electromagnetic drive or multiple driving modes. Under the action of the driving device, the telescopic device can freely extend and retract inside and outside the flow channel pier. When limiting, it is connected to the flap door to prevent the flap door from moving upward.

[0026] The flap door fixed axis rotation locking device is driven by hydraulic, mechanical, pneumatic, electromagnetic or water power single or multiple driving modes.

[0027] The fixed-axis vibration prevention and stop-at-anytime component adopts a slider damping method. The fixed-axis vibration prevention and stop-at-anytime component includes an upper slider, a lower slider, a retractable closed water-stop and a driving device. The sliders are installed on both sides of the flap door. Pneumatic or hydraulic mechanical retractable driving devices are arranged inside or outside the sliders. The fixed-axis vibration prevention and stop-at-anytime component is achieved by the friction between the slider extension and the flow channel pier.

[0028] Or: the fixed-axis vibration prevention and stop-at-anytime component adopts an airbag damping method, and the fixed-axis vibration prevention and stop-at-anytime component includes an airbag and a built-in spring. When there is no air, it is close to the fixed side; when inflated, the gate pier or flap gate that moves relative to the airbag generates friction with the relatively static airbag, thereby achieving fixed-axis vibration prevention and stop-at-anytime and reducing flap gate vibration. The airbag can be fixed to the flap gate, and the volume of the airbag is smaller at this time, but the weight of the flap gate increases; the airbag can be fixed to the flow channel pier, and the weight of the flap gate is the smallest at this time, which is the preferred solution.

[0029] The driving walking support track is installed with an extension and lowering device. When the extension and lowering device is lowered to the bottom plate of the flow channel, the flap door is placed flat on the bottom plate of the flow channel to realize the function of ship passage; when the extension and lowering device is raised to the high point of the flood, the maximum flood discharge capacity function can be met.

[0030] A vertical column or component is set in the middle of the flow channel; a slide slot and a foldable component are set on the outside of the vertical supports on both sides of the flap gate. These two schemes provide lateral force resistance for the flap gate, and neither is directly installed on the flap gate. Therefore, under the premise that the weight of the flap gate does not increase, the stress and deformation of the flap gate can be greatly improved, the plane size of the flap gate and the flow channel size are increased, thereby increasing the flow capacity; a flap gate pull ear is set at the bottom of the double-control flap gate. In special cases, the flap gate pull ear can be used in conjunction with an automatic grab beam (a common mechanical lifting device for a certain gate) to achieve power-assisted opening.

[0031] The technical concept of the present invention is: based on the research on double-controlled flap doors, the present invention adds a stop-at-anytime function after one-way opening, controls the opening degree of the flap doors, and realizes the flow control function.

[0032] The present invention adds a bidirectional function based on the research of double-controlled flapping doors: through the flapping door with Y-axis translation + fulcrum rotation, a limiting device (such as a buoy limiting device) is set, and one flapping door has the bidirectional function of controlling drainage or water diversion at the same time.

[0033] The present invention can realize bidirectional control of fluid by a single flap door through rotation around a support and translation of the support in the downstream direction, that is, control the introduction or discharge of fluid.

[0034] The beneficial effects of the present invention are mainly manifested in: it has the bidirectional functions of controlling drainage and water diversion at the same time; with the research and development and widespread application of composite materials in large aircraft in the aviation field and domestic wind turbines (impeller diameter 126m, blade length 61.5m, single blade mass 18 tons), the time is ripe to use composite flap doors. The composite double-controlled bidirectional flap door reduces the weight of the flap door, and uses hydraulic conditions, a plane walking device, and a locking device to realize the opening and closing functions of the sluice gate.

[0040] The present invention will be further described below in conjunction with the accompanying drawings.

[0041] Reference Figure 1 to Figure 5 A double-control flap door bidirectional system includes a double-control flap door system 1, a flap door translation system 2 and a flap door translation limit system 3. The double-control flap door system 1 includes a double-control flap door 11, a flap door support 12, a flap door seat 13, a flap door fixed axis rotation locking device 14, an anti-collision pad 15 and a flap door pull ear 16. The flap door fixed axis rotation locking device 14 includes a locking hole 141, a locking pin 142, a reinforced honeycomb plate 143 and a fixed axis anti-vibration stop assembly 144; the flap door translation system 2 includes a driving device 21, a driving walking support rail 22, a driving limit device 23 and a translation link beam 24; the flap door translation limit system 3 includes a limit device 31 (movable) and 32-35 finger limit assemblies, and the limit device 31 includes a float 311 and a slide bar 312. There are 6 flap door working positions, including PMWZ1 to PMWZ6. Figure 4 and Figure 5 These are two typical cases of the fixed-axis vibration-proof stop-at-anytime component 144, specifically the slider damping method and the airbag damping method. The slider damping fixed-axis vibration-proof stop-at-anytime component includes an upper slider 101, a lower slider 102, a retractable closed water stop 103, and a driving device 104. The airbag damping fixed-axis vibration-proof stop-at-anytime component includes an airbag and a built-in spring 202.

[0042] The double-control flap door of this embodiment rotates with a fixed axis to respectively complete the basic functions of drainage or water diversion. It belongs to the double-control category of flap doors. For details, please refer to the invention patent, named "double-control flap door", patent number: ZL2014 1 0777814.6.

[0043] Drainage: When the water level of the inner river is greater than the water level of the outer river, the double-control flap gate can be in a closed state under the joint action of the "locking hole 141, locking pin 142 or fixed-axis anti-vibration stop assembly 144" of the "flap gate fixed-axis rotation locking device 14", and the river channel is cut off. When the double-control flap gate is unlocked, the flap gate automatically opens under the action of hydraulic force. When it is located at "PMWZ2", the "finger limit assembly 32 or 33" and the "144 fixed-axis anti-vibration stop assembly" are activated, and the flap gate completes the locking under the open condition, realizing the function of controlling the drainage flow. Under special circumstances, power-assisted opening can also be achieved by cooperating with the flap gate pull ear 16 and the automatic grab beam (a mechanical lifting device commonly used for a certain gate).

[0044] Water diversion: When the water level of the outer river is greater than that of the inner river, the method is the same as that of the drainage condition. Under the joint action of the locking hole, locking pin, anti-vibration stop damping block or limiting position device, the water diversion flow is in a closed state or the water diversion flow is controlled.

[0045] On the basis of the research on double-control flap door, a stop function after one-way opening is added. A fixed axis anti-vibration stop component 144 is arranged on the side of the flap door, so that the flap door opening degree can be controlled at any time to realize flow control and flap door anti-vibration functions.

[0046] The driving mode of the fixed axis anti-vibration stop at any time component 144 can be hydraulic, mechanical, pneumatic, electromagnetic drive, water power, etc. Single or multiple driving and locking forms. Typical anti-vibration stop at any time modes include slider damping and airbag damping.

[0047] Slider damping method: including upper slider 101, lower slider 102, retractable closed water stop 103, and drive device 104. The slider is installed on both sides of the flap door, and the slider has a built-in or external pneumatic or hydraulic mechanical retractable drive device. Of course, the drive device 104 can also be an external mechanical retractable drive device. The fixed axis vibration prevention and stop at any time are achieved through the friction between the slider extension and the flow channel pier.

[0048] Airbag damping method: including airbag and built-in spring 202. When it is empty, it is close to the fixed side; when it is inflated, the gate pier or flap door moving relative to the airbag generates friction with the relatively static airbag, so as to achieve fixed axis vibration prevention and stop at any time and reduce flap door vibration. The airbag can be fixed to the flap door, in which case the airbag volume is small, but the flap door weight increases; the airbag can be fixed to the flow channel pier, in which case the flap door weight is the smallest, which is the preferred method.

[0049] The double-controlled flap gates move in parallel to complete the two-way conversion between drainage and water diversion functions, or complete automatic closure under hydraulic action. Through translation, after the flap gates are switched, one flap gate has the two-way function of controlling drainage or water diversion at the same time, and can be used as a substitute for traditional gates, especially small and medium-sized sluice gates.

[0050] Two-way dual-control function 1: "PMWZ1" moves to "PMWZ6", realizing the functions of drainage closure - drainage opening - drainage flow controllable - drainage closing - water diversion closure.

[0051] Drainage can be closed: PMWZ1, when the inner river water level > the outer river water level, the double-controlled flap gate can remain in a closed state under the joint action of the "locking hole 141, locking pin 142 or fixed-axis anti-vibration stop assembly 144" of the "flap gate fixed-axis rotation locking device 14", and the flow channel is cut off.

[0052] Drainage opening: PMWZ1, when the double-control flap door lock 14 is released or the anti-vibration stop is partially released, the flap door opens automatically or slowly under the action of water power. In special cases, power-assisted opening can also be achieved by cooperating with the flap door pull ear 16 and the automatic grab beam (a common mechanical lifting device for some gates).

[0053] The drainage flow is controllable: when the "finger limit component 32 or 33" and the "144 fixed-axis anti-vibration stop at any time component" located in "PMWZ2" are actuated, the door is flapped to activate the locking or damping function, thereby realizing the function of controlling the drainage flow.

[0054] Drainage closure: 2 flap gate translation system opens and drives, flap gate moves to "PMWZ3" under the action of 22 driving walking support track and hydraulic force, and rotates around slide bar 312 under the limit of 31 limit device (active) of 3 flap gate translation limit system, and moves to "PMWZ4", flap gate continues to translate, and after leaving the slide bar, the inner river water level > outer river water level, flap gate falls, affected by 34 / 35 finger limit, to "PMWZ5", open 23 driving limit, 12 flap gate support and 24 translation link beam fixed in the limit position of water diversion working condition. 144 anti-vibration stop opening at any time, because the inner river water level > outer river water level, flap gate automatically or slowly closes at "PMWZ6" under the action of hydraulic force.

[0055] Water diversion can be closed: When "PMWZ6" and "flap gate fixed axis rotation locking device 14" are in action, even if the internal and external water level conditions change, when the external river water level > the internal river water level, the flap gate remains closed, realizing the water diversion closure function, and the flow channel is cut off.

[0056] Two-way dual-control function 2: "PMWZ6" moves to "PMWZ1", realizing the functions of water diversion can be turned off - water diversion is turned on - water diversion flow is controllable - water diversion is closed - drainage can be turned off.

[0057] The two functions have the same principle, and the door is the same, but the door movement is reverse symmetrical. Specifically, the bidirectional invented operating system will be further explained with function one as a representative.

[0058] When the double-controlled flap gate is located at PMWZ1 and PMWZ2, it belongs to the three states before the double-controlled flap gate drainage flow is controllable, namely, drainage can be closed - drainage is open - drainage flow is controllable. The latter two states are bidirectional double-control processes. The driving device 21 needs to be turned on, and the flap gate is located at PMWZ3 by driving the walking support track 22 and the translation link beam 24. Due to the action of the limit device 31 (active), the flap gate moves to PMWZ4 and then to PMWZ5. Since the water level of the inner river is greater than the water level of the outer river, when the finger limit components 34 and 35 are activated, the flap gate can be prevented from falling rapidly. The flap gate automatically closes the drainage under the action of hydraulic power, and the driving limit 23 acts to fix the flap gate at PMWZ6; the "flap gate fixed axis rotation locking device 14" is activated to realize the water diversion closable function. The drainage function of the double-controlled flap gate fixed axis rotation is transformed into the basic function of water diversion.

[0059] The bidirectional system of the double-controlled flap door of this embodiment is mainly used in the liquid flow channel of the bidirectional water level. One flap door completes the drainage and diversion functions. The core of the bidirectional system is the 2-flap door translation system, including linear and curved translation. The drive can be hydraulic, mechanical, pneumatic, electromagnetic drive, etc., single or multiple drive forms, the purpose is to enable the hydraulic automatic flap door to achieve the bidirectional water level function. The 3-flap door translation limit system is an auxiliary device for completing the bidirectional water level function.

[0060] Based on the research of double-control flap door, the function of stopping at any time after one-way opening is added. The fixed-axis anti-vibration stop at any time is set on the side of the flap door, which can control the flap door opening degree at any time to realize the flow control and flap door anti-vibration function. The driving mode of the fixed-axis anti-vibration stop at any time can be hydraulic, mechanical, pneumatic, electromagnetic drive, hydraulic and other single or multiple drive and locking forms. Typical anti-vibration stop at any time has slider damping and airbag damping methods.

[0061] In order to reduce the hydraulic loss when the flap door is automatically opened and increase the buoyancy of the flap door, the flap door can be filled with helium.

[0062] Implementation example of maximum flood discharge and ship passage: It is allowed to install a vertical extending and lowering device on the "22 drive walking support track". When the extending and lowering device is lowered to the bottom plate of the flow channel, the flap gate is placed flat on the bottom plate of the flow channel to realize the ship passage function; when the extending and lowering device is raised to the high point of the flood, the maximum flood discharge capacity function can be met.

[0063] Embodiments for increasing flow capacity: when a vertical column or component is arranged in the middle of the flow channel; when a slideway and a foldable component are arranged outside the vertical supports on both sides of the flap door. These two solutions provide lateral force resistance support for the flap door, and neither is directly installed on the flap door. Therefore, under the premise that the weight of the flap door is not increased, the stress and deformation of the flap door can be greatly improved, and the plane size of the flap door and the flow channel size are increased, thereby increasing the flow capacity.
