Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic gates, in particular to a novel flat-open floating tide-blocking gate structure. Background Art

[0002] According to the tide prevention experience of important coastal cities at home and abroad, building tide gates at the estuary is an effective way to improve the city's tide prevention capacity. For example, the Thames Estuary Gate in London, England, and the New Waterway Tide Gate in the Netherlands have played an important role in the tide prevention and disaster reduction of these cities. As a coastal country, my country has a large number of rivers flowing into the sea, and the banks of the rivers are basically important cities with developed economies. With the continuous rise in global sea levels and the continuous intensification of ground subsidence, storm surge intrusions have seriously affected the safety of life and property of people in the areas surrounding the river. Relying solely on the measures of continuously raising and strengthening the flood control wall projects on both sides of the river, there are huge investments, poor landscape effects, large land use constraints behind the wall, long construction period, and limited efficiency. It cannot be used as a sustainable choice for improving the flood control capacity of coastal cities. By building gates at the estuary to form an urban flood control system combining "tide gates + flood control walls", the resilience of estuary cities in flood control can be enhanced.

[0003] The gate type is an important consideration in the construction of tide gates. Different gate types have a significant impact on the site selection, land occupation, navigation, river flow, siltation, landscape effect, etc. Looking at the experience of large tide gate construction in coastal cities around the world, the large-span tide gate type is currently mainly the Maasland tide gate in the Netherlands and the St. Petersburg tide gate in Russia, which uses a flat-opening pontoon fan-shaped door, with the largest single-hole net width reaching 360m. Except for the flat-opening pontoon fan-shaped door, the single-hole span of other gate types is not large.

[0004] Although the flat-opening pontoon fan-shaped gate has many advantages such as mature technology, safety and reliability, easy maintenance, clever use of buoyancy, and ability to achieve ultra-large span water retaining, it occupies a large area, and the sill of the sluice must be at the same elevation. It cannot be applied to the natural river section and will change the riverbed morphology near the gate site, thereby causing siltation or scouring. Therefore, this type of gate cannot be used when the land on both sides is limited or the natural river section is seriously deviated.

[0005] Therefore, the applicant has found a solution to the above-mentioned problem through beneficial exploration and research, and the technical solution to be introduced below is produced in this context. Utility Model Content

[0050] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0051] See also Figures 1 to 7 The figure shows a novel horizontally-opened floating tide-blocking gate structure, including a tide-blocking gate 100, one end of which is rotatably arranged in a bank door storehouse 10, as shown in FIG. Figure 6 As shown in FIG. 1 , when it is necessary to block the tide, the tide-blocking gate 100 rotates around its rotation fulcrum to the tide-blocking position in the middle of the river channel to block the tide, as shown in FIG. Figure 7 shown.

[0052] The tide-blocking gate 100 includes a floating gate body 110 , a plurality of flip-up door mechanisms 120 , and a plurality of hanging door mechanisms 130 .

[0053] The interior of the floating gate body 110 adopts a steel structure hollow box structure, in which a gate body filling and drainage system (not shown in the figure) is arranged. The floating gate body 110 can be sunk below the water surface by filling with water, and the floating gate body 110 can be floated by pumping water. A steel structure truss 111 is arranged at one end of the floating gate body 110, and a ball joint 112 is arranged at the end of the steel structure truss 111 away from the floating gate body 110. The floating gate body 110 is installed in a ball joint seat 11 arranged at the bank gate 10 through the ball joint 112, so that the tide gate 100 can rotate around its rotation fulcrum, so that the tide gate 100 can be rotated and opened horizontally.

[0054] Due to the water level difference when blocking the tide, the side surfaces of the end of the floating gate body 110 contact the side surfaces of the piers 20 on both sides, forming a classic simply supported beam structure. The structural force is clear, and the force characteristics are that the bending moment is large in the middle and small at both ends. In order to adapt to its force characteristics, the plane of the floating gate body 110 is a shuttle-shaped structure that is wide in the middle and narrow at both ends, which improves the stability of the structure.

[0055] The front and rear side surfaces of the floating gate body 110 are arc-shaped curved surfaces 110a, which are convenient for reducing water resistance during the overall rotation and opening of the tide-blocking gate 100.

[0056] The floating gate body 110 can be regarded as a simply supported beam structure, and the end of the floating gate body 110 is the resting end of the simply supported beam. In order to improve the resting effect of the floating gate body 110, the two ends of the floating gate body 110 are rectangular steel structure empty box resting ends 115, and the top surface elevation is not lower than the defense elevation; when the tide-blocking gate 100 rotates to the tide-blocking position in the middle of the river channel and is filled with water and sunk, the rectangular steel structure empty box resting ends 115 formed at the two ends of the floating gate body 110 are correspondingly rested in the gate grooves 21 of the side piers 20 on both sides of the river channel. Among them, the top surface elevation of the tide-blocking outer side of the gate groove 21 is lower than the top surface elevation of the tide-blocking inner side, and the top surface elevation of the tide-blocking outer side of the gate groove 21 is lower than the bottom surface elevation of the floating gate body 110 when it floats on the water surface.

[0057] Several flip door mechanisms 120 are arranged side by side on the top surface of the floating gate body 110 along the length direction, and they use buoyancy to open and close. In this embodiment, the flip door mechanism 120 uses buoyancy to automatically open and close, and includes a flip door 121 and a flip door limiter.

[0058] The interior of the flip door 121 adopts a steel structure hollow box structure, one side of which is rotatably arranged on the top surface of the floating gate body 110 through the flip door rotating shaft 1211. The buoyancy provided by the flip door 121 is greater than its overall gravity. When the water level is high, the flip door 121 will automatically float up with the water level and automatically open by buoyancy. A flip door accommodating groove 113 for accommodating the flip door 121 is formed on the top surface of the floating gate body 110. When the flip door 121 is in a non-tide-proof state, the flip door 121 flips to a horizontal state and is located in the flip door accommodating groove 113.

[0059] The upper flip door limiting device is arranged on the top surface of the floating gate body 110, and is used to limit the upper flip door 121. The upper flip door limiting device is a plurality of gate piers 122 arranged at intervals on the top surface of the floating gate body 110, and the distance between two adjacent gate piers 122 is equivalent to the door width of the upper flip door 121. As the water level rises, the upper flip door 121 will rotate around the upper flip door shaft 1211 to float and block the water. In order to prevent the upper flip door 121 from being overturned when the water level is high, the gate pier 122 is set to limit the position, that is, after the upper flip door 121 rotates to a certain angle, due to the obstruction of the gate pier 122, the upper flip door 121 stops on the gate pier 122 and will not rotate further. In addition, the gate pier 122 also has the effect of landscape shaping. Alternatively, the upper flip door limiting device adopts a limiting cable, one end of which is connected to the top surface of the floating gate body 110, and the other end is connected to the upper flip door 121. When the upper flip door 121 rotates to a certain angle, the limiting cable is straightened, and the upper flip door 121 is limited at this time to prevent the upper flip door 121 from flipping over.

[0060] Of course, the upper flip door mechanism can also be opened and closed in other ways. For example, the upper flip door mechanism includes an upper flip door, an upper flip door opening and closing device, and an upper flip door limiting device. The upper flip door adopts a non-empty box structure, one side of which is rotatably arranged on the top surface of the floating gate body through the upper flip door shaft. The upper flip door opening and closing device is arranged on the top surface of the floating gate body, which is used to drive the upper flip door to flip. The upper flip door limiting device is arranged on the top surface of the floating gate body, which is used to limit the upper flip door. Among them, the upper flip door opening and closing device can adopt a hydraulic rod device, a winch opening and closing machine or a rotating shaft driving device. The upper flip door limiting device is the same as the above-mentioned upper flip door limiting device, which will not be repeated here.

[0061] In addition, the upward-flipping door mechanism 120 can also use a fixed retaining wall fixedly arranged on the top surface of the floating gate body to block water.

[0062] Several hanging door mechanisms 130 are arranged side by side on the bottom surface of the floating gate body 110 along the length direction, and they use buoyancy to open and close. In this embodiment, the hanging door mechanism 130 uses buoyancy to realize automatic opening and closing, and includes a hanging door 131 and a hanging door filling and drainage system (not shown in the figure).

[0063] The interior of the hanging door 131 adopts a steel hollow box structure, one side of which is rotatably arranged on the bottom surface of the floating gate body 110 through the hanging door rotating shaft 1311. A hanging door accommodating groove 114 for accommodating the hanging door 131 is formed on the bottom surface of the floating gate body 110. When the hanging door 131 is in a non-tide-proof state, the hanging door 131 flips to a horizontal state and is located in the hanging door accommodating groove 114.

[0064] The buoyancy provided by the hanging door 131 is greater than its gravity. The hanging door filling and drainage system is arranged in the hanging door 131, which is used to fill water or drain water into the empty box structure in the hanging door 131, and the hanging door 131 can be drooped by filling water, and can be floated by pumping water.

[0065] Of course, the hanging door mechanism can also be opened and closed in other ways. For example, the hanging door mechanism includes a hanging door and a hanging door opening and closing device. The hanging door adopts a non-empty box structure, one side of which is rotatably arranged on the bottom surface of the floating gate body through the hanging door shaft. The hanging door opening and closing device is arranged on the bottom surface of the floating gate body, which is used to drive the hanging door to flip. Among them, the hanging door opening and closing device adopts a hydraulic rod device, a winch hoist or a rotating shaft driving device.

[0066] The working principle of the new flat-open floating tide-blocking gate structure of the utility model is introduced as follows:

[0067] The tide-blocking gate 100 of the present invention is usually docked in the bank door storehouse 10. Figure 6 As shown in the figure, it can be used as a water platform for people to rest and visit. When blocking the tide, it can be towed to the tide blocking position in the middle of the river by a tugboat to achieve the tide blocking function. Figure 7 shown.

[0068] When the tide gate 100 is opened and rotated to the center of the river channel by the tugboat around the ball joint in the direction of the water flow, the interior of the floating gate body 110 is not filled with water or is filled with a small amount of water. At this time, the floating gate body 110 floats on the water surface. Figure 8 shown.

[0069] After the tide gate 100 rotates to the center of the river channel, the floating gate body 110 is filled with water and sinks, and is placed in the gate groove 21 of the piers 20 on both sides. At this time, the floating gate body 110 is completely submerged in the water, and the upper flip door mechanism 120 on the upper part of the floating gate body 110 will float to a certain extent under the action of buoyancy. Fig. 9 shown.

[0070] The top surface elevation of the tide-blocking outer side of the gate slot 21 of the side piers 20 on both sides is lower than the top surface elevation of the tide-blocking inner side. Fig.10 As shown, one side of the gate groove 21 is higher, and the higher side contacts the end side of the floating gate body 110, as shown in FIG. Fig.11 As shown, the other side bears the water pressure transmitted by the floating gate body 110, and is lower than the bottom elevation of the floating gate body 110 when floating on the water surface, otherwise the floating gate body 110 will hit this place during the rotation and floating process.

[0071] After the floating gate body 110 is lowered, the hanging gate mechanism 130 is filled with water, and the hanging gate mechanism 130 is turned down to the bottom sill 30 of the sluice gate by its own weight to block water. Since the hanging gate mechanism 130 blocks the water flow, the water level outside the gate continues to rise with the tide, and the flip-up gate mechanism 120 automatically floats up, using buoyancy to automatically block water. Fig.12 At this time, a large head difference is formed inside and outside the gate.

[0072] The design of the hanging door mechanism 130 has three major advantages: first, it has good adaptability to siltation. Even if there is a certain amount of siltation on the riverbed, it will not affect the normal opening and closing of the hanging door mechanism 130; second, it can actively adjust the elevation of the sluice sill 30 in combination with the riverbed shape (at this time, the height of the hanging door mechanism 130 at the corresponding position is also adjusted synchronously). Fig.13 As shown, the river section at the gate construction location is made closer to the natural river section, thereby alleviating the problems of scouring and siltation caused by the change of the river channel morphology due to the gate construction; thirdly, during the process of the floating gate body 110 rotating to open and sink, the hanging door mechanism 130 is retracted without blocking the water flow, so the water blocking area during the operation of the floating gate body 110 rotating to open and sink is small, which can avoid unfavorable water flow conditions during the operation as much as possible.

[0073] At this point, the gate has achieved its tide-blocking function. At this point, the force on the entire gate is relatively clear, that is, the water pressure borne by the flip-up door mechanism 120 is transmitted to the floating gate body 110, and the floating gate body 110 itself also bears the water pressure within its height range. The water pressure borne by the hanging door mechanism 130 is partially transmitted to the floating gate body 110, and the other part is transmitted to the sill 30 of the sluice. From the top view, the floating gate body 110 is a simply supported beam force structure subjected to uniform load, with the largest bending moment in the mid-span and the largest shear force at both ends. The side piers 20 on both sides bear the horizontal force transmitted by the floating gate body 110.

[0074] After the tide blocking is completed, the hanging gate mechanism 130 is pumped out, and the hanging gate mechanism 130 is retracted by buoyancy, and the hanging gate mechanism 130 returns to the bottom of the floating gate body 110. Then the floating gate body 110 is drained and floats on the water surface, and then the tide blocking gate 100 is towed to the bank gate 10 by a tugboat, and the river channel resumes flow and navigation.

[0075] The utility model only has a sluice sill 30 in the sluice-type river channel, so the daily maintenance workload is small and the impact on navigation is small; the tide-blocking gate 100 is usually docked on the shore and can be maintained on the shore, so the daily operation and maintenance conditions are good. The utility model has many advantages such as being able to block water with a large span, clear force, safe and reliable operation, being able to freely arrange the riverbed in accordance with the current situation, convenient maintenance and repair, cleverly utilizing buoyancy, occupying a small area, not affecting navigation during non-tide-blocking periods, and being able to adapt to a certain amount of siltation.

[0076] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
