Technical Field

The utility model belongs to irrigation and water conservancy, municipal administration, traffic, mechanical equipment device and fluid field, especially a two-way two accuse system of clapping. Bidirectional, means that one flap valve is controlled to realize two flow states of water diversion (diversion from outside water to inside river) or drainage (drainage from inside river to outside river); the double control refers to that the flap valve has the function of closing and opening under the high pressure of internal water.

Background

The gate and the opening and closing device are control devices arranged on various overflowing pore canals of the overflowing building and are important components of the overflowing building. The gate can adjust the flow and the water level when opened or closed so as to achieve the purposes of flood control, irrigation, power generation, navigation, wood passing, sand discharge, ice discharge, floating discharge and the like.

Dividing the whole plane into a whole plate and a beam grid type gate according to the shape of the gate; the panel may be in the form of a flat or curved surface. Depending on the moving mode, there are vertical lift type, horizontal (push) pull type, rotary type, floating box type, and horizontal lift type plane gate. The horizontal pulling type plane gate can move transversely along the track and is only suitable for being operated under still water conditions. The rotary plane gate is divided into horizontal axis rotation (flap gate, flap gate and flap gate) and vertical axis rotation (straight gate and herringbone gate). The buoyancy tank type plane gate can only be operated under still water condition, and is generally used as an overhaul gate.

When selecting the opening and closing device, the following factors should be considered: the type, size and operation of the gate, the number of openings, the opening and closing forces, and sometimes the holding force, the opening and closing stroke, the opening and closing speed, the number and spacing of the lifting points, the power conditions, the space size of the installation site, and the building conditions are also considered. The type of the gate determines the structural scheme of the lock chamber, the opening and closing mode, the flow state of the overflowing, the management and operation facilities and personnel allocation, the traffic on the gate and the foundation treatment scheme, and the construction and safety cost and the management and operation are greatly influenced.

According to the first national water conservancy general survey bulletin, the standard time point of general survey is 12 months and 31 days in 2011, and the general survey period is 2011. The sluice flow rate is 1 cubic meter per second or more, 268476 seats of sluice and 2685 seats of rubber dam.

The width of the single-hole gate is less than or equal to 6m and accounts for 95.5%, less than or equal to 5m and accounts for 92.7%, and the width of the single-hole gate accounts for 65.5%. Therefore, the study on the gate with the single-hole clear width less than or equal to 6m has universality and universality.

1. the fulcrum rotates. The typical application is that a transverse shaft rotates (a flap door, a flap door and a flap door), and the flap door is divided into an upper flap and a lower flap; vertical axis rotation (straight and miter gates); an arc (fan) shaped gate.

2. Straight up and straight down (Z-axis motion trajectory). Typical applications include fixed wheels, sliding wheels, chain wheels, and reverse hooks; the motion trail of the special plane gate with lifting and horizontal type is vertical lifting, rotation and translation.

3. Push-pull (X-axis, motion trajectory perpendicular to the direction of water flow), a typical application is a cross-pull gate. Occupies more space for opening and closing the walking track.

4. The Y-axis (motion trajectory in the direction of water flow) is less useful, and a typical application is a float box gate.

5. Translation in the Y-axis direction and rotation of a fulcrum are not applied.

The movement track of the gate is mostly pivot rotation, straight up and straight down (Z-axis movement track) or push-pull (X-axis and movement track vertical to the water flow direction), and more space for opening and closing the walking track is occupied; the Y-axis (motion trajectory in the direction of water flow) is less useful, and a typical application is a float box type flat gate. The gate with the motion track of translation in the Y-axis direction and rotation of the fulcrum has no relevant research and application.

The general gate adopts steel and reinforced concrete, has heavy dead weight and needs large opening and closing equipment. With the research and development and wide application of composite materials of large airplanes and domestic wind turbine sets (impeller diameter 126m, blade length 61.5m and single blade mass 18 tons) in the aviation field, the time of the gate adopting the composite materials is mature, and the application of the gate of the composite materials of the middle and small water gates is not common at present.

Belonging to the double-control category of flap valve. See utility model patent, the name "two accuse clap door" for details, patent number: ZL 201410777814.6.

Draining stagnant water: when the inland river water level is higher than the inland river water level, the double-control flap valve can be in a closed state under the combined action of the locking hole 141 of the flap valve fixed-shaft rotation locking device 14, the locking pin 142 or the fixed-shaft vibration-proof instant stop assembly 144, and the river channel is cut off. When the double-control flap valve is unlocked, the flap valve is automatically opened under the action of water power, and when the flap valve is positioned at PMWZ2, the finger limiting component 32 or 33 and the 144 dead-axle vibration-proof instant stop component act, so that the flap valve is locked under the opening working condition, and the function of controlling the drainage flow is realized. In special cases, power-assisted opening can also be realized by matching the flap door pull lug 16 with an automatic grabbing beam (a certain type of common gate mechanical lifting device).

Water diversion: when the water level of the external river is higher than that of the internal river, the method is in a closed state or controls the diversion flow under the combined action of the locking hole, the locking pin and the anti-vibration stop damping block at any time or the limiting device under the same drainage working condition.

On the basis of double-control flap valve research, a function of stopping at any time after unidirectional opening is added. A fixed shaft anti-vibration instant stop assembly 144 is arranged on the side of the flap valve, so that the opening degree of the flap valve can be controlled at any time, and the flow control and flap valve anti-vibration functions are realized.

The driving mode of the fixed-axis anti-vibration stop-and-go assembly 144 can be a single or multiple driving and locking mode such as hydraulic, mechanical, pneumatic, electromagnetic driving, hydraulic, etc. The typical vibration prevention is stopped at any time by a slide damping mode and an air bag damping mode.

Clinging to the fixed side when no air exists; when the air bag is inflated, the gate pier or the flap valve moving relative to the air bag generates friction force with the air bag which is relatively static, so that the fixed shaft vibration prevention can be realized, and the flap valve vibration can be reduced. The air bag can be fixed with the flap valve, and the air bag has smaller volume but the flap valve has increased weight; the air bag can be fixed with the runner pier, and the flap valve has the smallest weight at the moment, which is a priority mode.

The double-control flap valve moves in parallel to complete the bidirectional conversion between the functions of drainage or diversion or complete the automatic closing under the action of water power. After the flap valve is shifted by translation, one flap valve has a bidirectional function of controlling drainage or water diversion at the same time, and can be used as a substitute of a traditional gate, particularly a small and medium-sized sluice gate.

The first two-way double control function is as follows: the 'PMWZ 1' is moved to 'PMWZ 6', so that the functions of closing drainage, starting drainage, controlling drainage flow, closing drainage and closing water diversion are realized.

Drainage can be closed: when the PMWZ1, inland river water level > the inland river water level, the double-control flap valve can still be in a closed state under the combined action of the locking hole 141, the locking pin 142 or the fixed-shaft anti-vibration instant stop assembly 144 of the flap valve fixed-shaft rotation locking device 14, and the flow channel is cut off.

And (3) draining waterlogging and starting: and PMWZ1, when the double-control flap door lock 14 is released or the vibration-proof stop-motion part is released, the flap door is automatically or slowly opened under the action of water power. In special cases, power-assisted opening can also be realized by matching the flap door pull lug 16 with an automatic grabbing beam (a certain type of common gate mechanical lifting device).

The drainage flow is controllable: when the 'finger limiting component 32 or 33' and the '144 dead axle anti-vibration anytime stopping component' positioned in the 'PMWZ 2' act, the flap valve starts the locking or damping function, and the function of controlling the drainage flow is realized.

And (3) draining and closing waterlogging: the 2 flap valve translational system is driven to be opened, the flap valve moves to 'PMWZ 3' under the action of 22 driving walking support tracks and water power, the flap valve rotates around the slide rod 312 under the limitation of a floating body 311 and a slide rod 312 of a 31 limiting device (movable) of a 3 flap valve translational limiting system, the flap valve continues to translate after moving to 'PMWZ 4', the flap valve is separated from the slide rod, the inland river water level is greater than the inland river water level, the flap valve falls down and is influenced by 34/35 finger limiting, the flap valve reaches 'PMWZ 5', 23 driving limiting is opened, and a 12 flap valve support and a 24 translational connecting beam are fixed at a limiting position of a water diversion working condition. 144 is stopped and opened at any time in a vibration-proof way, and the flap valve is automatically or slowly closed at 'PMWZ 6' under the action of water power because the water level of the inland river is greater than the water level of the inland river.

The diversion can be closed: when the PMWZ6 and the flap valve fixed-axis rotation locking device 14 act, even if the conditions of the internal water level and the external water level change, the flap valve is still closed when the external water level is greater than the internal water level, the function of closing the water diversion is realized, and the flow channel is cut off.

A two-way double control function II: the PMWZ6 is moved to PMWZ1 to realize the functions of water diversion closing, water diversion opening, water diversion flow rate control, water diversion closing and drainage closing.

The two functional principles are the same, the flap door is also the same, but the flap door motion is in reverse symmetry. And particularly, a first function is taken as a representative to continuously supplement and explain the operating system of the bidirectional utility model.

When the double-control flap valve is positioned at PMWZ1 and PMWZ2, the double-control flap valve belongs to 3 states before the drainage flow is controllable, namely drainage can be closed, drainage is opened and drainage is controllable. The latter two states are two-way dual control processes. The driving device 21 is required to be opened, the flap valve is positioned at the PMWZ3 by driving the walking support track 22 and the translational coupling beam 24, and the flap valve walks to the PMWZ4 and then to the PMWZ5 under the action of the limiting device 31 (activity). Since the inland river water level is greater than the inland river water level, the flap valve can be prevented from falling rapidly when the finger limiting assemblies 34 and 35 are started. The flap valve automatically drains waterlogging and closes under the action of water power, drives the limit 23 to act, and is fixed on the PMWZ 6; the flap valve fixed shaft rotation locking device 14 is started to realize the function of water diversion and closeability. The function of draining the stagnant water by the rotation of the fixed shaft of the double-control flap valve is converted into the basic function of water diversion.

The two-way system of the double-control flap valve is mainly applied to a two-way water level liquid flow passage, and one flap valve finishes the functions of drainage and water diversion. The core of the bidirectional system is a 2-flap valve translation system which comprises linear translation and curvilinear translation, and the drive can be a single or multiple drive modes such as hydraulic, mechanical, pneumatic, electromagnetic drive and the like, so that the hydraulic automatic flap valve can realize a bidirectional water level function. The 3-flap valve translation limiting system is an auxiliary device for completing a bidirectional water level function.

On the basis of double-control flap valve research, a function of stopping at any time after unidirectional opening is added. The fixed shaft is arranged on the side of the flap valve to prevent vibration and stop at any time, so that the opening degree of the flap valve can be controlled at any time, and the flow control and flap valve vibration prevention functions are realized. The driving mode of the fixed shaft vibration prevention and stop at any time can be a single or multiple driving and locking modes such as hydraulic, mechanical, pneumatic, electromagnetic driving, hydraulic and the like, and a typical vibration prevention and stop at any time is provided with a slide block damping mode and an air bag damping mode.

In order to reduce the hydraulic loss of the automatic opening of the flap valve and increase the buoyancy of the flap valve, the flap valve can be filled with helium.

Maximum flood flow and vessel traffic examples: the '22-drive walking support rail' is allowed to be provided with the vertical extension and descent device, and when the extension and descent device descends to the runner bottom plate, the flap valve is horizontally arranged on the runner bottom plate, so that the ship passing function is realized; when the lifting device rises to a flood high point, the function of the maximum flood-running and overflowing capacity can be met.

Embodiment for increasing overcurrent capacity: when a vertical upright post or a component is arranged in the middle of the flow channel; when the outside of the vertical supports at the two sides of the flap valve is provided with a chute and a foldable component. The two schemes provide lateral force resisting support for the flap valve, and the flap valve is not directly arranged on the flap valve, so that the stress and deformation of the flap valve can be greatly improved on the premise of not increasing the weight of the flap valve, the plane size and the flow passage size of the flap valve are increased, and the flow capacity is increased.
