Description

Technical Field

[0001] The present invention relates to the technical field of flow pattern optimization in a plane asymmetric sluice station combined with an engineering forebay, and in particular to a movable track-changing guide wall and an operation method thereof. Background Art

[0002] In traditional plain sluice and pump station hub layouts, sluices and pump stations are often arranged separately. This effectively solves the problem of connecting water flows upstream and downstream of the hub. However, this layout occupies a large area. To address this large hub footprint, sluices and pump stations are combined. The combined sluice and pump station layouts are categorized into plane-symmetrical, plane-asymmetrical, and vertical-layered arrangements. In particular, in plane-asymmetrical arrangements, when the pumps and sluices operate independently, the water flow forms a certain angle with the riverbed, altering the original flow pattern and momentum distribution of the river channel. This creates a left-right momentum imbalance in the riverbed, causing severe backflow and lateral flow upstream and downstream of the hub, worsening the inlet flow pattern of the sluice and pump station, reducing the sluice discharge capacity or pump station efficiency, and even severely scouring the bank slope, endangering building foundations and threatening project safety.

[0003] In asymmetrical layouts, diversion walls are typically installed to improve flow patterns. While this doesn't completely eliminate backflow before the gate, it can reduce the impact on the gate's discharge. However, existing diversion walls are fixed in length and position, and cannot be flexibly adjusted based on factors such as the velocity and direction of the upstream flow at different times. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to propose a movable track-changing guide wall and an operation method thereof, which can be used to optimize the flow pattern of the forebay of an asymmetric sluice station combined with an engineering project under different working conditions.

[0005] Based on the above objectives, the present invention provides a movable track-changing guide wall, which is arranged in the forebay of a sluice station. A diversion canal is provided at the water inlet end of the forebay, and a regulating gate and a pump station flow channel are arranged side by side at the water outlet end of the forebay, comprising:

[0006] The guide rail device is installed in the forebay. The guide rail device is located at the front end of the intersection of the regulating gate and the pump station flow channel. The outlet end of the guide rail device away from the forebay is provided with two arc-shaped bifurcated sections.

[0007] Fixed diversion wall, the fixed diversion wall includes a fixed wall body with an internal hollow design, a gate is provided at one end of the fixed wall body, and a movable diversion wall assembly is provided at one end of the gate. The movable diversion wall assembly includes diversion wall bodies arranged along the length direction of the fixed wall body, and a flexible sleeve telescopic assembly is connected between each diversion wall body. A roller assembly is connected to the bottom of the diversion wall body, and the roller assembly is slidably connected to the guide rail device so that the diversion wall body can slide along the guide rail device to any arc-shaped bifurcation section, or retract into the interior of the fixed diversion wall.

[0008] Preferably, the fixed wall body is made of concrete casting.

[0009] Preferably, a guide wall support portion is fixedly provided on the guide wall body.

[0013] Preferably, a waterproof cloth assembly is provided on the outer side of the movable guide wall assembly, and the waterproof cloth assembly includes a waterproof cloth body and a steel wire inserted into the waterproof cloth body.

[0014] Preferably, the guide rail device includes two layers of arc guide rails, guard rails, wing rails, movable point rails and switch rods. A track wall is connected between the upper and lower layers of arc guide rails. The guard rails are attached to the inner side of the arc guide rails. The wing rails are arranged at the bifurcation of the arc guide rails. The movable point rails are rotatably connected to the rear end of the wing rails. The wing rails and the movable point rails are arranged opposite to each other on both sides of the bifurcation of the arc guide rails. The switch rod is connected to the side end of the movable point rail. In the initial state, the movable point rails on both sides respectively abut the arc guide rails on the same side. By pulling the switch rod on one side, the movable point rail is driven to rotate away from the arc guide rail on the same side, so that the guide wall body slides along the arc guide rail on the same side.

[0015] Preferably, one end of the switch rod passes through the guide rail device and is connected to a switch machine for driving the switch rod to move telescopically.

[0016] The present invention also provides an operating method of a movable track-changing guide wall, comprising:

[0017] For the control brake operation status:

[0018] When rapid flood discharge is not required, the regulating gate is opened for self-drainage. The switch lever on the right is pulled by the switch machine to drive the movable point rail on the right to rotate away from the curved guide rail on the right. The movable point rail on the left remains in its initial state. The gate of the fixed diversion wall is opened to allow the movable diversion wall assembly to move out of the fixed diversion wall. The roller assembly drives the diversion wall body to slide onto the curved guide rail on the right, forming a curved diversion wall on the right.

[0019] After the self-drainage is completed, the control gate is closed, and the guide wall body is driven back to the fixed guide wall through the roller assembly, the gate is closed, and the switch machine pushes the right turnout rod to drive the right movable point rail to rotate closer to and away from the right curved guide rail, returning to the initial state;

[0020] For the pump station flow channel operation status:

[0021] When rapid flood discharge is required, the water pump on the flow channel of the pumping station is turned on for pumping and drainage. The switch lever on the left is pulled by the switch machine to drive the movable point rail on the left to rotate away from the curved guide rail on the left. The movable point rail on the right remains in its initial state. The gate of the fixed diversion wall is opened to allow the movable diversion wall assembly to move out of the fixed diversion wall. The roller assembly drives the diversion wall body to slide onto the curved guide rail on the left, forming a curved diversion wall on the left.

[0022] After the pumping is completed, the water pump on the flow channel of the pump station is turned off, and the main body of the diversion wall is driven back to the fixed diversion wall through the roller assembly. The gate is closed, and the switch rod on the left is pushed through the switch machine to drive the movable point rail on the left to rotate closer to and away from the arc guide rail on the left, and return to the initial state.

[0023] The beneficial effects of the present invention are as follows: through the guide rail device provided in the forebay, the guide rail device is located at the front end of the intersection of the regulating gate and the pump station flow channel, the guide rail device is provided with two arc-shaped bifurcated sections at the water outlet end away from the forebay, the movable guide wall assembly includes a guide wall body arranged along the length direction of the fixed wall body, a flexible sleeve telescopic assembly is connected between each guide wall body, a roller assembly is connected to the bottom of the guide wall body, and the roller assembly is slidably connected to the guide rail device so that the guide wall body slides along the guide rail device to any arc-shaped bifurcated section, or retracts into the interior of the fixed guide wall, and the future water flow is predicted according to the weather forecast system, and then according to the experience of setting up guide walls in similar projects in the database, the position of the guide wall is determined and the length of the entire guide wall is changed by changing the number of guide wall devices, thereby optimizing the water flow pattern at the water pump and the water gate inlet. Under the self-draining working condition, the water flow can flow smoothly into the water gate side through the self-draining channel, reducing the impact on the water gate discharge. Under pumping and drainage conditions, ensure that the flow velocity distribution at the pump chamber inlet is relatively uniform to avoid the situation where the inlet flow pattern of the water pump closest to the sluice is relatively turbulent.

[0040] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to specific embodiments.

[0042] like Figures 1 to 13As shown, a movable guide wall with a changeable track is provided in the forebay 6 of the sluice station. A diversion canal 8 is provided at the water inlet end of the forebay 6. A regulating gate 5 and a pump station flow channel 1 are provided side by side at the water outlet end of the forebay 6. The guide wall comprises a guide rail device 4 provided in the forebay 6. The guide rail device 4 is located at the front end of the junction of the regulating gate 5 and the pump station flow channel 1. The guide rail device 4 is provided with two arc-shaped bifurcated sections at the water outlet end away from the forebay 6. The fixed guide wall 2 comprises a fixed wall body 2-1 with an internal hollow design, and a gate is provided at one end of the fixed wall body 2-1. The door 2-3 and the gate 2-3 are provided with a movable guide wall assembly 3 at one end. The movable guide wall assembly 3 includes a guide wall body 3-1 arranged along the length direction of the fixed wall body 2-1. A flexible sleeve telescopic assembly 3-3 is connected between each guide wall body 3-1. A roller assembly is connected to the bottom of the guide wall body 3-1. The roller assembly is slidably connected to the guide rail device 4 so that the guide wall body 3-1 can slide along the guide rail device 4 to any arc-shaped bifurcation section, or retract into the interior of the fixed guide wall 2.

[0043] Specifically, the layout diagram of the sluice station combined with the project forebay is as follows: Figure 1 As shown:

[0044] The right side is the water pump side, and the left side is the sluice side. A trash gate 7 is installed between the forebay 6 and the diversion canal 8. The fixed diversion wall 2, the movable diversion wall assembly 3 and the guide rail device 4 can manually adjust the position and length of the movable diversion wall assembly 3 according to the pumping (pump station working, sluice gate closed) and self-draining conditions (sluice gate open, pump station shut down), thereby optimizing the flow state of the forebay water.

[0045] The fixed guide wall 2 includes a fixed wall body 2-1 with an internal hollow design. The fixed guide wall body 2-1 is 10.8m high, 3.2m wide, and 26m long. The interior of the fixed guide wall body 2-1 is hollow. A 25×1.2×8.8m rectangular parallelepiped is hollowed out from the width×height side close to the movable guide wall assembly 3. The overall structure is cast with concrete and has sufficient strength to resist the erosion of water flow. Preferably, a guide rail device 4 is also provided on the bottom surface of the fixed guide wall body 2-1. The movable guide wall assembly 3 can be moved along the guide rail device 4 and retracted into the fixed guide wall body 2-1 to prevent the movable guide wall assembly 3 from being damaged by the extremely large impact force of the water flow. At the same time, the fixed guide wall 2 itself can also improve the flow state of the water flow. In addition, the provision of a fixed guide wall 2 can avoid the movement of the common part of the guide wall required for pumping and self-draining. The length of the movable guide wall assembly 3 is reduced, saving waste of steel. At the same time, it can avoid the situation where the length of the movable guide wall component 3 is too long and difficult to turn. The gate 2-3 is set on the width × height side of the fixed guide wall body 2-1 close to the movable guide wall component 3. The structure is a flat steel gate. The hoist 2-2 can be used to control the lifting of the gate 2-3. The hoist 2-2 is placed on the upper part of the gate 2-3, and a 2×2×2m space is reserved on the upper part of the fixed guide wall body 2-1 to place the hoist 2-2. The specific structure is as follows Figure 2 shown.

[0046] The movable diversion wall assembly 3 includes a diversion wall body 3-1 arranged along the length of the fixed wall body 2-1. The diversion wall body 3-1 is constructed of stainless steel, with the length of the stainless steel corresponding to the length, width, and height of the diversion wall body 3-1. The width and thickness are all 0.2m. After the assembly is completed, there is a hollow section in the middle. This effectively saves steel material compared to a solid rectangular parallelepiped, and the weight is not too heavy, which can save driving power. At the same time, to increase the strength of the movable diversion wall assembly 3 and resist the impact of incoming water, a diversion wall support portion 3-2 can be added to the side of the length × height surface. The diversion wall support portion 3-2 is in an "X" shape, with a thickness of 0.2m and a height of 8.2m, protruding into the interior of the diversion wall body 3-1.

[0047] A drive unit 3-8 and a roller control unit 3-9 are installed below the main body 3-1 of the diversion wall. With the bottom surface of the main body 3-1 as the bottom surface, the unit is 0.2m high, forming a closed frame with a hollow interior. The frame is 0.2m thick, and the drive unit 3-8 and roller control unit 3-9 are installed in the hollowed-out portion. The drive unit 3-8 provides power for the movement of the movable diversion wall assembly 3, and the roller control unit 3-9 can intelligently control the start and end of the movement of the movable diversion wall assembly 3. A roller assembly is installed below the main body 3-1 to drive the movable diversion wall assembly 3 on the guide rail assembly 4. The roller assembly includes wheels 3-4, rims 3-5, and axles 3-6, all of which are made of stainless steel. The structure of the roller assembly imitates that of a train wheel. The rims 3-5 on the inner side of the wheels 3-4 ensure that the assembly will not derail while moving on the guide rail assembly 4. The radius of the wheel 3-4 is 0.6m and the thickness is 0.5m. The radius of the rim 3-5 is 0.7m and the thickness is 0.1m. The radius of the axle 3-6 is 0.2m and the length is 2.4m. It just passes directly through the inside of the wheel 3-4, with a length of 1.2m reserved in the middle, which is adapted to the width of a single movable guide wall assembly 3.

[0048] At the same time, 6 flexible sleeve telescopic devices 3-3 are added to the length × height side of the guide wall body 3-1, and two flexible sleeve telescopic devices 3-3 are evenly arranged at the upper, middle and lower parts of the guide wall body 3-1. The position distribution is as follows: Figure 4 As shown, even when the movable guide wall assembly 3 moves on the curved guide rail, it has a certain degree of flexibility to deflect in an arc. The material of the rubber expansion sleeve 3-3-3 of the flexible sleeve expansion and contraction device 3-3 is natural rubber, which has the advantages of good elasticity and shock absorption, while allowing a small amount of deflection and expansion and contraction. The rubber expansion sleeve 3-3-3 has a production length of 0.6m and a radius of 0.1m, and its external structure is a telescopic structure. The hook 3-3-1 and the nut 3-3-2 are made of stainless steel, which gives them sufficient strength to connect the two movable guide wall assemblies 3. The hook 3-3-1 and the nut 3-3-2 are cast as a whole. The height of the hook 3-3-1 is 0.08m and the thickness is 0.05m. The arc of the hook is a 7 / 8 arc with an arc radius of 0.03m. The nut 3-3-2 is an equilateral hexagonal nut with a circumscribed circle radius of 0.08m and a height of 0.04m. A hook 3-3-1 and a nut 3-3-2 are installed at the upper and lower ends of the rubber expansion sleeve 3-3-3, respectively, so that the movable guide wall device 3 can be flexibly added or removed according to the changes in water level.

[0049] Since the entire structure of the movable guide wall component 3 is hollow, water will flow out from the gap, causing the flow to become more turbulent. Therefore, it is necessary to cover the surface of the guide wall body 3-1 with a waterproof cloth 3-7 to prevent water from passing through the movable guide wall component 3 and effectively improve the flow state in the forebay. Figure 13As shown. A waterproof cloth assembly 3-7 is provided on the outside of the movable guide wall assembly 3. The waterproof cloth assembly 3-7 includes a waterproof cloth body 3-7-1 and a steel wire 3-7-2 inserted into the waterproof cloth body 3-7-1. The material of the waterproof cloth 3-7-1 is PVC coated cloth. This material does not contain harmful substances and has excellent water-resistant properties. It will not affect the aquatic ecological environment even if it is soaked in water. Moreover, the cloth is soft, has high tensile strength, and is not easy to crack. Even if the movable guide wall assembly 3 is exposed to the water surface, it is not easy to cause ultraviolet aging when exposed to sunlight. At the same time, it will not be damaged during the multiple expansion and contraction processes of the movable guide wall assembly 3. In addition, in order to increase the tensile strength of the waterproof cloth 3-7-1 and prevent it from breaking during multiple expansion and contraction processes, a steel wire 3-7-2 can be inserted into the waterproof cloth 3-7-1. The diameter of the steel wire 3-7-2 is 3mm.

[0050] The distance between each two steel wires 3-7-2 is 0.5m. The length, width and height of the waterproof cloth 3-7 are respectively the length, width and height of the movable diversion wall device 3 when stretched, plus the deformation length of the rubber expansion sleeve 3-3-3 of 0.2~0.4m, with a thickness of 4mm. It is put on the movable diversion wall component 3 and tied and fixed to the movable diversion wall component 3 with a rope 3-7-3 of the same material as the waterproof cloth 3-7-1. The overall structure of the diversion wall is as follows Figure 12 shown.

[0051] The guide rail device 4 includes two layers of arc-shaped guide rails 4-1, an upper arc-shaped guide rail 4-1-A and a lower arc-shaped guide rail 4-1-B, which can effectively limit the up and down displacement of the roller assembly. Figure 5 、 6 The position of the guide rail device 4 in the entire project is shown. The top view of the guide rail device 4 is a "Y"-shaped structure, with the intersection of the regulating gate and the pump station flow channel as the fork of the two curved guide rails 4-1. The height is 0.2m, and the interval between the two parallel guide rails on the same track is 1.2m, corresponding to the length reserved for the axles 3-6. The AA cross-sectional view of the guide rail device 4 is a horizontal "concave" structure, with the outer side surfaces of the upper and lower layers of the track connected with stainless steel to form a track wall 4-4. The length of the track wall 4-4 is consistent with the track, with a height of 1.4m and a thickness of 0.02m. The installation of the track wall 4-4 can increase the anti-overturning ability of the entire device. The specific situation is as follows Figure 7As shown. According to the numerical simulation optimization of the actual project or drawing on the experience of existing projects, the arc radius arrangement method that can best improve the flow state is determined. In this example, the straight track is 20m long, the arc guide rail 4-1 has an arc of 60° and a radius of 15m, and the arc guide rails 4-1 on both sides are symmetrically distributed. A guard rail 4-2 is added at the fork to guide the wheel 3-4 and prevent the wheel 3-4 from moving to the wing rail 4-3-1 due to turning, causing the wheel 3-4 to derail and thus roll over. The guard rail 4-2 is 1m long and the same height as the guide rail device 4. It is 0.05m thick and is arranged on the inner side of the two outermost rails. The material of the guide rail device 4 is stainless steel, which can prevent the entire device from corroding and rusting in water for a long time, thereby increasing the service life of the guide rail device 4.

[0052] A movable guide rail 4-3 is provided at the fork of the guide rail device 4, including a wing rail 4-3-1 and a movable point rail 4-3-2. The wing rail 4-3-1 and the movable point rail 4-3-2 are arranged opposite to each other along the two sides of the fork of the arc-shaped guide rail 4-1, namely the left movable point rail 4-3-2-B and the right movable point rail 4-3-2-A. The structural form is set according to the principle of train turning, such as Figure 8 、 9 As shown. At the place where the two curved guide rails 4-1 overlap, the two sections of wing rails 4-3-1 are extended forward by 0.3m, which can effectively prevent rollover at the place where the two curved guide rails 4-1 overlap. The section of track behind the wing rail 4-3-1 is set as a movable point rail 4-3-2, and the length of this section of movable point rail 4-3-2 is 2m. The movable point rail 4-3-2 can be rotated around the axis of the intersection with the wing rail 4-3-1 through the switch pull rod 4-5 installed on the side, and the rotation angle is 20°. By changing the length of the switch pull rod 4-5, including the left switch pull rod 4-5-B and the right switch pull rod 4-5-A, the corresponding movable point rail 4-3-2 is pulled to rotate, and the movable point rail 4-3-2 on one side is moved away from the guide rail device 4, allowing the movable guide wall assembly 3 to pass through the guide rail on the other side. The command to control the length of the switch pull rod 4-5 is issued through the switch machine 4-6, and the switch machine 4-6 is set on one side of the track. The switch machine 4-6 has a safety feature inside. If the movable switch rail 4-3-2 is not switched into place, an alarm will be sounded through the line to remind the staff to carry out maintenance. By pulling the switch lever 4-5 on one side, the movable switch rail 4-3-2 is driven to rotate away from the curved guide rail 4-1 on the same side, so that the guide wall body 3-1 slides along the curved guide rail 4-1 on the same side.

[0053] The present invention also provides an operating method of a movable track-changing guide wall, comprising:

[0054] The pump station flow channel 1 and the regulating gate 5 are not in operation, the movable point rail 4-3-2 is not moved, the movable point rails 4-3-2 on both sides are respectively abutted against the arc guide rail 4-1 on the same side, the movable guide wall assembly 3 is retracted into the fixed guide wall 2, and the gate 2-3 of the fixed guide wall 2 is closed and set to the initial state;

[0055] For the operating status of control brake 5:

[0056] When rapid flood discharge is not required, for example, according to the weather forecast system, the upcoming rainfall is predicted to be less than the flood control reservoir capacity, the regulating gate 5 is opened for self-drainage, and then the specific position of the movable diversion wall component 3 is determined in advance based on the experience of setting the diversion wall position of similar projects in the database, and then the gate 2-3 opening signal is sent to the control system, and the control system issues a command for the movable diversion wall component 3 to turn right and a command for the movable diversion wall component 3 to the final stop position.

[0057] Pull the right turnout lever 4-5-A on the right side through the switch machine 4-6, driving the right movable point rail 4-3-2-A on the right side to rotate away from the right curved guide rail 4-1, and stop after rotating 20°. The left movable point rail 4-3-2-B on the left side remains in its initial state. Open the gate 2-3 of the fixed guide wall, let the movable guide wall assembly 3 move out of the fixed guide wall 2, and drive the guide wall body 3-1 to slide onto the right curved guide rail 4-1 through the roller assembly. For details, see Figure 10 , the control system issues a command to the roller control device 3-9, the roller control device 3-9 issues a command to the wheel 3-4 to roll and the drive device 3-8 to provide power to the roller device, so that the wheel 3-4 moves along the guide rail device 4, thereby driving the movable guide wall assembly 3 to move to a determined position, and then the roller control device 3-9 issues an end command, at this time the drive device 3-8 no longer provides power, the movable guide wall assembly 3 can stop, forming a curved guide wall on the right side, which can improve the flow state of the water flow, allowing the water flow to flow smoothly into the sluice side through the self-draining channel, reducing the impact on the sluice discharge;

[0058] After the self-draining is completed, the control gate 5 is closed, and the guide wall body 3-1 is driven back to the fixed guide wall 2 through the roller assembly, and the gate 2-3 is closed. The right turnout lever 4-5-A on the right side is pushed by the switch machine 4-6, driving the right movable point rail 4-3-2-A on the right side to rotate closer to and away from the right curved guide rail 4-1. After rotating 20°, it stops and returns to the initial state. For details, see Figure 8 ;

[0059] For the pump station flow channel operation status:

[0060] When rapid flood discharge is required, for example, according to the weather forecast system, the upcoming rainfall is predicted to be greater than the flood control reservoir capacity, the water pump on the pump station flow channel 1 is turned on for pumping and drainage, and then the specific position of the movable diversion wall component 3 is determined in advance based on the experience of setting the diversion wall position of similar projects in the database, and then the gate 2-3 opening signal is sent to the control system, and the control system issues a command for the movable diversion wall component 3 to turn left and a command for the movable diversion wall component 3 to the final stop position.

[0061] Pull the left turnout lever 4-5-B on the left side through the switch machine 4-6, driving the left movable point rail 4-3-2-B on the left side to rotate away from the left curved guide rail 4-1, and stop after rotating 20°. The right movable point rail 4-3-2-A on the right side remains in its initial state. Open the gate 2-3 of the fixed guide wall 2, and let the movable guide wall assembly 3 move out of the fixed guide wall 2. Drive the guide wall body 3-1 to slide onto the left curved guide rail 4-1 through the roller assembly. For details, see Figure 11 , the control system issues a command to the roller control device 3-9, the roller control device 3-9 issues a command to the wheel 3-4 to roll and the drive device 3-8 to provide power to the roller device, so that the wheel 3-4 moves along the guide rail device 4, thereby driving the movable guide wall assembly 3 to move to a determined position, and then the roller control device 3-9 issues an end command, at this time the drive device 3-8 no longer provides power, the movable guide wall assembly 3 can stop, forming an arc-shaped guide wall on the left, which can improve the water flow pattern, ensure that the flow velocity distribution at the pump chamber inlet is more uniform, and avoid the situation where the inlet flow pattern of the water pump closest to the sluice side is more turbulent;

[0062] After the pumping is completed, the water pump on the flow channel 1 of the pump station is turned off, and the guide wall body 3-1 is driven back to the fixed guide wall 2 by the roller assembly. The gate 2-3 is closed, and the left turnout lever 4-5-B is pushed by the switch machine 4-6, driving the left movable point rail 4-3-2-B on the left to rotate closer to and away from the left curved guide rail 4-1. After rotating 20 degrees, it stops and returns to the initial state. For details, see Figure 8 .
