Abstract
Description
Technical Field
[0001] The utility model relates to a water retaining sluice, in particular to a hydraulically driven two-way water retaining sluice. Background Art
[0002] A sluice is a low-head hydraulic structure that uses gates to retain and discharge water, and is widely used in water conservancy projects. Drainage sluices are often built along rivers to drain waterlogging harmful to crops in inland rivers or low-lying areas. When the water level of the outer river rises, the sluice is closed to prevent backflow of external water. When there is a lot of stagnant water in the depression and it is higher than the water level of the outer river, the sluice is opened to discharge water, having the characteristic of two-way water retaining. Tide gates are built near the estuaries of the sea. When the tide is rising, the gates are closed to prevent seawater from flowing back, and when the tide is ebbing, the gates are opened to discharge water, also having the characteristic of two-way water retaining. The early built two-way water retaining sluices do not necessarily have the characteristic of automatic opening and closing.
[0003] The opening and closing of large and medium-sized sluices are generally driven by electricity to drive a winch to open. In extreme weather or special circumstances, the power supply may be interrupted, resulting in the inability of the two-way water retaining sluice to open and close normally. When the water level of the outer river / high tide is high and the gate is not closed in time, the water of the outer river / seawater flows back; when the water level of the outer river / high tide is low and the gate is not opened in time, the stagnant water area / inland river water level cannot be drained in time, which will surely cause certain economic losses. Summary of the Invention
[0004] The technical problem to be solved by the utility model is to provide a hydraulically driven two-way water retaining sluice, which can be used as an alternative for non-electric traction automatic opening and closing, and has good energy-saving effects through hydraulic control.
[0005] To solve the above technical problems, the technical solution adopted by the utility model is:
[0006] A hydraulically driven two-way water retaining sluice includes a working gate. Both ends of the working gate are placed in pier. A working bridge is arranged at the upper end of the pier. An upstream floating box retaining wall and a downstream floating box retaining wall are respectively arranged on the upstream and downstream sides of the pier. An upstream traction system is installed in the upstream floating box retaining wall, and a downstream traction system is installed in the downstream floating box retaining wall. The upstream traction system and the downstream traction system open or close the working gate when the water level changes.
[0007] The pier includes a pier body and a gate slot, and the gate slot matches the working gate and positions the working gate.
[0008] The working bridge includes columns, and a cross beam is arranged at the top of the columns.
[0009] The upstream traction system includes an upstream traction hook, an upstream pulley system, an upstream floating box, and an upstream fixed end; the upstream traction hook is fixed on the upper end surface of the working gate on the left and right; the upstream pulley system is arranged along the bottom of the working bridge, pier, upstream floating box retaining wall, and the bottom of the upstream floating box; the upstream fixed end is located at the bottom of the upstream floating box; the cable passes around the upstream pulley system, with one end connected to the upstream fixed end and the other end connected to the upstream traction hook.
[0010] The upstream pulley system includes a middle pulley on the crossbeam, an upper pulley on the crossbeam, an end pulley at the upstream pier, a middle pulley at the upstream pier, a bottom pulley at the upstream pier, a traction pulley at the bottom of the upstream retaining wall, and a bottom pulley of the upstream floating box.
[0011] The downstream traction system includes a downstream traction hook, a downstream pulley system, a downstream fixed end, and a downstream floating box. The downstream traction hook is arranged at the top of both sides of the working gate, and the downstream fixed end is located at the bottom of the downstream floating box retaining wall; the cable passes around the downstream pulley system, with one end connected to the downstream fixed end and the other end connected to the downstream traction hook.
[0012] The downstream pulley system includes a first pulley at the downstream pier, a second pulley at the downstream pier, a bottom pulley at the downstream pier, and a bottom pulley of the downstream floating box.
[0013] The upstream floating box retaining wall and the downstream floating box retaining wall are in a portal structure and are equal in height to the gate; an upstream water inlet is provided at the bottom of the upstream floating box retaining wall, a downstream water inlet is provided at one-third of the height of the downstream floating box retaining wall, and a flap gate is provided at the bottom.
[0014] The inner wall of the upstream floating box retaining wall is provided with an upstream floating box guide rail. The upstream floating box is located inside the upstream floating box retaining wall and contacts the upstream floating box guide rail through a rolling wheel; the inner wall of the downstream floating box retaining wall is provided with a downstream floating box guide rail. The downstream floating box is located inside the downstream floating box retaining wall and contacts the downstream floating box guide rail through a rolling wheel.
[0015] The present utility model provides a hydraulically driven two-way water retaining gate, which has the following technical effects:
[0016] 1). By arranging an upstream traction system and a downstream traction system upstream and downstream of the working gate, and utilizing the water level changes upstream and downstream to drive the upstream floating box and the downstream floating box to move up and down, thereby opening or closing the gate. Through hydraulic control, it has a good energy-saving effect.
[0017] 2). In addition, this device can effectively prevent the backflow of the outer river water / sea water when the water level of the outer river / tide is relatively high.
[0018] 3) The pulley systems of the upstream traction system 2 and the downstream traction system 3 are different: The upstream traction system 2 is used to lift the gate, and the downstream traction system 3 is used to close the gate. There is one more pulley at the bottom of the downstream floating box than at the bottom of the upstream floating box. For every 1 m the downstream floating box rises, 4 m of cable can be driven by 4 fixed pulleys at the bottom to pull the gate downwards, thus closing the gate; for every 1 m the upstream floating box rises, only 3 m of cable can be driven by 3 fixed pulleys at the bottom to lift the gate upwards. When the upstream floating box rises by 1 / 3 of the gate height, the gate can be fully opened, and when the downstream floating box rises by 1 / 4 of the gate height, the gate can be fully closed.
[0019] When the upstream and downstream floating boxes rise simultaneously, a new balance can be achieved when the upstream water level is about 4 / 3 times that of the downstream water level (the downstream water level is 3 / 4 of the upstream water level). When the downstream water level exceeds 3 / 4 of the upstream water level, the gate can still be closed under the buoyancy of the downstream floating box and the gravity of the gate. When the upstream water level exceeds 4 / 3 of the downstream water level, the gate can be partially opened. Brief Description of the Drawings

[0030] The inner side of the two-way floodgate mainly includes flood detention areas, small river channels in the city, and large rivers on the inner side of the estuary. The main function is to prevent the backflow of river water during the flood outbreak in the upper reaches of the outer river or the backflow of seawater during high tide. When it is a flood detention area, the inner side of the floodgate is generally low-lying. For example, the Gong'an Jingjiang Flood Detention Area has a large flood detention function. When it is a small river channel in the city, the water level of the inner river is generally adjusted through urban lakes, or the advocated sponge city concept is applied. If it is a large river, the water level of the inner river is adjusted through upstream reservoirs.
[0031] As Figure 1 shown, a hydraulically driven two-way floodgate includes a working gate 4, pier 5, working bridge 6, upstream traction system 2, downstream traction system 3, upstream floating box retaining wall 7, downstream floating box retaining wall 8, upstream floating box guide rail 9, and downstream floating box guide rail 10.
[0032] As Figure 3 shown, the pier 5 is located at both ends of the working gate 4. The pier 5 includes a pier body 51 and a gate slot 52. The gate slot 52 is used to place the working gate 4. The working bridge 6 is located on top of the pier 5 and includes columns 61 and cross beams 62, mainly used to arrange the upstream traction system 2.
[0033] As Figure 2 shown, the upstream traction system 2 is located on the upstream side of the gate 5 and within the width range of the pier 5. The upstream traction system 2 includes an upstream traction hook 21, a middle pulley on the cross beam 22, an upper pulley on the cross beam 23, an upstream pier end pulley 24, an upstream pier middle pulley 25, an upstream pier bottom pulley 26, an upstream retaining wall bottom traction pulley 27, an upstream floating box bottom pulley 28, an upstream floating box 29, and an upstream fixed end 30.
[0034] As Figure 5 shown, there are 2 upstream traction hooks 21 in the upstream traction system 2, which are respectively located at the top of the working gate 4 at the edges of the piers 5 at both ends of the cross-river working gate 4. One end of the upstream traction hook 21 is connected to a cable, and the other end is fixed to the top of the working gate.
[0035] As Figure 2 shown, the upstream traction system 2 is connected by cables. The cables bypass the upstream pulley system. One end of the cable is connected to the corresponding upstream fixed end 30, and the other end is connected to the upstream traction hook 21.
[0036] In the upstream pulley system: The middle pulley 22 of the crossbeam and the upper pulley 23 of the crossbeam are both located at the edge of the top of the working bridge 6 near the gate hole side; the middle pulley 25 of the upstream pier, the bottom pulley 26 of the upstream pier, the bottom pulley 27 of the upstream retaining wall, the bottom pulley 28 of the upstream floating box, and the fixed end 30 are located on the center line of the upstream floating box 29 along the river direction. The center line of the upstream floating box 29 along the river direction is not flush with the edge of the gate hole side of the working bridge, so the end pulley 24 of the upstream pier and the middle pulley 25 of the upstream pier are required to deflect the cable. The upstream fixed end 30 of the upstream traction system 2 is located at the bottom of the floating box along the center line of the floating box 29 in the river direction. The upstream floating box 29 drives the upstream traction system 2 to rotate around the upstream pulley system under the action of the buoyancy force, driving the working gate 4 to open.
[0037] As Figure 2 shown, the downstream traction system 3 is located within the width range of the pier 5 on the downstream side of the gate. The downstream traction system 3 includes a downstream traction hook 31, a first downstream pier pulley 32, a second downstream pier pulley 33, a bottom pulley 34 of the downstream pier, a bottom pulley 35 of the downstream floating box, a downstream fixed end 36, and a downstream floating box 37.
[0038] The downstream traction system 3 is connected by a cable. The cable bypasses the downstream pulley system. One end of the cable is connected to the downstream traction hook 31, and the other end is connected to the downstream fixed end 36.
[0039] As Figure 5 shown, there are 2 downstream traction hooks 31 of the downstream traction system 3. The downstream traction hooks 31 are respectively located at the tops of both side faces of the working gate 4 within the gate slot 51. One end of the downstream traction hook 31 is connected to the traction cable, and the other end is fixed to the side face of the working gate 4.
[0040] The downstream traction hook 31, the first downstream pier pulley 32, the second downstream pier pulley 33, the bottom pulley 34 of the downstream pier, the bottom pulley 35 of the downstream floating box, and the downstream fixed end 36 are all located on the center line of the downstream floating box 37 along the river direction. The downstream floating box 37 drives the downstream traction system 3 to rotate around the downstream pulley under the action of the buoyancy force, driving the working gate 4 to close.
[0041] As Figure 1-2 shown, the upstream floating box retaining wall 7 and the downstream floating box retaining wall 8 are respectively located on the upstream and downstream sides of the pier 5 and are connected to the pier 5. The horizontal planes of the upstream floating box retaining wall 7 and the downstream floating box retaining wall 8 are in an inverted U structure, with a length of 6 m, a thickness of 30 cm, and a height equal to the height of the gate 4.
[0042] An upstream water inlet 71 is provided at the bottom of the upstream floating box retaining wall 7 to connect the water outside the retaining wall; a downstream water inlet 81 is provided at the 1 / 3 height of the downstream floating box retaining wall 8, and a flap gate 82 is provided at the bottom to connect the water outside the retaining wall.
[0043] The flap gate 82 is a commonly used gate at the outlet of pipelines of hydraulic structures, etc. It is generally only circular or square, in various sizes. Here, a square flap gate is adopted.
[0044] The upstream floating box guide rail 9 is located in the upstream floating box retaining wall 7 of the gate pier 5, and two upstream floating box guide rails 9 are provided on each of the three inner walls of the upstream floating box retaining wall 7. The downstream floating box guide rail 10 is located in the downstream floating box retaining wall 8 of the gate pier 5, and two downstream floating box guide rails 10 are provided on each of the three inner walls of the downstream floating box retaining wall 8. The heights of the upstream floating box guide rail 9 and the downstream floating box guide rail 10 are equal to the height of the gate 4.
[0045] The upstream floating box 29 is located in the upstream floating box retaining wall 7, and the downstream floating box 37 is located in the downstream floating box retaining wall 8. The upstream floating box 29 contacts the upstream floating box guide rail 9 through a rolling wheel, and the downstream floating box 37 contacts the downstream floating box guide rail 10 through a rolling wheel. The upstream floating box 29 and the downstream floating box 37 are 5 m long, 2 m wide, and 2 m high.
[0046] Principle and process of operation:
[0047] 1) As Figure 6 shown, when the water levels upstream and downstream are both relatively low, specifically: the upstream water level does not exceed 1 / 3 of the retaining wall height, and the downstream water level does not exceed the downstream water inlet 81. The downstream flap gate 82 is closed (the flap gate 82 closes the drainage hole at the bottom of the downstream retaining wall), and the upstream floating box 29 drives the traction system to open the working gate 4 under the buoyancy force, and the downstream cable is in a slack state. When the upstream water level reaches 1 / 3 of the retaining wall height and the downstream water level is lower than the water inlet 81, the gate opening is the largest, and the downstream cable is in a taut state.
[0048] 2) As Figure 7 shown, during the rainstorm period, when the water levels upstream and downstream both rise and are relatively high (the upstream water level exceeds 1 / 3 of the retaining wall height and the downstream water level also exceeds the water inlet 81), if the upstream water level reaches about 1.3 times the downstream water level, the gate can be partially opened to discharge the upstream waterlogging; if the upstream water level does not exceed 1.3 times the downstream water level, the gate remains closed.
[0049] 3) As Figure 8 shown, when the upstream water level does not exceed 1 / 3 of the retaining wall height and the downstream water level rises and exceeds the downstream water inlet 81, the flap gate 82 is closed, the external river water enters the downstream retaining wall, and the downstream floating box 37 drives the downstream traction system to close the gate 4 under the buoyancy force.
[0050] 4) As Figure 9 shown, when the downstream water level recedes, the water in the downstream retaining wall can be discharged through the downstream water inlet 81 and the flap gate 82. When the downstream water level is below 0.75 times the upstream water level, the gate opens for drainage; when the downstream water level is lower than the water inlet 81 and the upstream water level is still higher than 1 / 3 of the retaining wall height, the gate can be fully opened for drainage.
