Description

Technical Field

[0001] The present invention relates to the technical field of tidal energy power generation, and more specifically, to a bank protection structure for generating power using tidal energy. Background Art

[0002] The levee is an important project to protect the safety of the coast or river. The levee will be constantly eroded, especially the bank protection footing of the levee, which is an important structure to prevent the levee from collapsing.

[0003] In order to improve the embankment's ability to prevent tides and floods, it is necessary to add embankment protection structures to embankments that cannot meet the requirements of embankment protection. When building or renovating the embankment protection structure of an inland river embankment near the estuary, it will be affected by the sea tide. The concrete cast-in-place construction process has a construction working surface at low tide every day, and the construction time is short, which cannot meet the requirements of the cast-in-place construction process; adding a film bag sand cofferdam or a water-stop steel sheet pile cofferdam will greatly increase the construction cost. Therefore, the cast-in-place embankment concrete structure is not suitable for the construction of inland river embankment protection structures affected by tides.

The present application adopts the coordination between the gabion, the seepage layer and other structures. The gabion can reduce the impact of water flow on the land base while planting some vegetation. The seepage layer can avoid water accumulation on the road surface and plant trees.

DETAILED DESCRIPTION

[0036] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0037] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0038] like Figure 1-2 As shown, the present invention provides a bank protection structure for generating electricity using tidal energy, comprising a protection structure foundation, a protection structure main body and a tidal energy power generation unit, the protection structure main body comprising a prefabricated solid foot layer 1 and a prefabricated retaining wall 2, the prefabricated solid foot layer 1 is arranged on the top surface of the protection structure foundation, the prefabricated retaining wall 2 is arranged on the top surface of the prefabricated solid foot layer 1, and the tidal energy power generation unit is arranged on the outer surfaces of the prefabricated solid foot layer 1 and the prefabricated retaining wall 2.

[0039] Furthermore, the protective structure foundation includes a riprap footing layer 3 and a crushed stone cushion layer 4 and a concrete cushion layer 5 sequentially arranged on the riprap footing layer 3 , and the prefabricated footing layer 1 is arranged on the top surface of the concrete cushion layer 5 .

[0040] Furthermore, the prefabricated water retaining wall 2 includes a lower water retaining wall 6 and an upper water retaining wall 7 , and the lower water retaining wall 6 and the upper water retaining wall 7 are fixedly connected to the cast-in-place concrete layer 8 .

[0041] Further, a railing base 9 is arranged on the top surface of the upper retaining wall 7 and the cast-in-place concrete layer 8, the upper surface of the railing base 9 is arranged obliquely, the height of the upper surface of the railing base 9 close to the embankment is lower than the height of the upper surface of the railing base 9 far from the embankment, and a railing 10 is arranged on the upper surface of the railing base 9 along the length direction of the embankment, and the railing 10 is arranged perpendicular to the upper surface of the railing base 9;

[0042] A landscape walkway is arranged on the top surface of the cast-in-place concrete layer 8 close to the railing base 9 , and the landscape walkway is paved with natural stone strips 11 .

[0043] Furthermore, the prefabricated fixing foot layer 1 is formed by splicing a plurality of prefabricated fixing feet, and an expansion joint is arranged between adjacent prefabricated fixing feet along the length direction of the embankment. The width of the expansion joint is 2 cm, and the expansion joint is filled with BW closed-cell foam board. A geotextile 13 is laid on the surface of the embankment at the position of the expansion joint, and the geotextile 13 extends upward to the top of the embankment.

[0044] The working principle of the above technical solution is:

[0045] The embankment protection project is mainly a measure to prevent the erosion, scouring and shore trampling of the bank slope foundation soil by water flow and waves, so as to ensure the safety of the embankment slope.

[0046] The embankment protection structure for generating electricity by utilizing tidal energy comprises a protection structure foundation, a protection structure main body and a tidal energy power generation unit, wherein the protection structure main body comprises a prefabricated solid foot layer 1 and a prefabricated water retaining wall 2, the prefabricated solid foot layer 1 is arranged on the top surface of the protection structure foundation, the prefabricated water retaining wall 2 is arranged on the top surface of the prefabricated solid foot layer 1, tidal energy power generation units are arranged on the outer surfaces of the prefabricated solid foot layer 1 and the prefabricated retaining wall 2, and the prefabricated solid foot layer 1 and the prefabricated retaining wall 2 are arranged along the length direction of the embankment.

[0047] When constructing the embankment protection structure, the old protection structure of the embankment 100 is dismantled and then construction is carried out on the embankment 100, or construction is carried out directly on the embankment 100. The height of the prefabricated fixing foot layer is determined according to the average water level of the low tide and high tide, and the height and length of the prefabricated fixing foot, as well as the height of the retaining wall, are determined based on the weight of the prefabricated fixing foot.

[0048] When starting construction, first lay out the foundation pit control boundary line according to the design drawings, use wooden stakes as boundary control points, and use iron nails nailed on the wooden stakes as elevation control points, and use an excavator to carry out excavation construction.

[0049] Then proceed to level the bed:

[0050] Use excavators to dig and load, and dump trucks to transport the blocks directly to the dumping site. Use the dump truck end-in method to extend the vertical dumping forward. When dumping vertically, use layered water flow step-by-step dumping. The excavator cooperates with leveling, and the block stones are manually arranged on the surface. Construction is carried out according to the design requirements of the dumping section size. After the dumping is completed, the settlement observation should be carried out. The settlement rate should not exceed 0.5mm / d. After the settlement is completed, a dumping footing layer 3 is formed.

[0051] Pad construction:

[0052] After the settlement of the riprap footing layer 3 is stable, the cushion layer construction is carried out. The cushion layer material is divided into two layers. The bottom layer is the crushed stone cushion layer 4. After manual leveling with 20cm thick crushed stone, the top surface should meet the fine leveling standard. The fine leveling standard is that the top surface elevation error is within ±50mm. The upper layer is the concrete cushion layer 5. After leveling with 10cm thick C20 plain concrete, the top surface should meet the extremely fine leveling requirement. The extremely fine leveling requirement is that the top surface elevation error is within ±30mm.

[0053] Due to the short construction time, a full-time tide observer is arranged on site to promptly notify the construction personnel to remove the garbage, mud, etc. on the concrete cushion layer 5 when the tide recedes.

[0054] Before the prefabricated fixed feet are hoisted, the top of the embankment is repaired and well-graded gravel or coarse-grained soil is used for backfilling and compaction in layers to ensure that the compaction degree is not less than 96% to ensure the safe passage of the hoisting machinery.

[0055] Hoisting:

[0056] Use a lifting machine to lift the prefabricated fixing feet one by one into place. In the length direction of the embankment, a 2cm expansion joint is reserved between adjacent prefabricated fixing feet. The expansion joint is filled with BW closed-cell foam board. The surface of the embankment is laid with geotextile 13 at the position of the expansion joint. The geotextile 13 extends upward to the top of the embankment. Sealing paste can be filled between the upper and lower adjacent prefabricated fixing feet. The sealing paste can be polysulfide sealing paste. There is a gap between the prefabricated fixing feet and the embankment, which can be filled with crushed stone.

[0057] The position of the prefabricated fixed feet during hoisting requires different hoisting requirements according to different embankments and can be determined based on actual construction conditions.

[0058] The width of the expansion joint can be selected to be 2cm.

[0059] After the prefabricated fixing feet are hoisted, the retaining wall is hoisted. Steel bars can be pre-embedded on the top of the lower water retaining wall 6 close to the embankment, and steel bars can be pre-embedded on the side of the upper water retaining wall 7 close to the embankment. After the prefabricated fixing feet and the upper and lower water retaining walls are hoisted, the construction position is no longer affected by the water level. The cast-in-place concrete layer 8 can be poured on the inner side of the water retaining wall at the top of the embankment. Before pouring the cast-in-place concrete layer 8, the pre-embedded steel bars of the upper and lower water retaining walls can be welded to the steel bars of the cast-in-place concrete layer 8 to improve the strength of the entire embankment protection structure.

[0060] In order to facilitate the laying of the steel bars of the cast-in-place concrete layer 8, a plain concrete layer 12 is first poured on the top of the embankment. The thickness of the plain concrete layer 12 can be selected to be 10 cm.

[0061] In order to ensure the safety of pedestrians on the embankment, a railing base 9 is arranged on the top surface of the upper retaining wall 7 and the cast-in-place concrete layer 8. The upper surface of the railing base 9 is inclined, and the height of the upper surface of the railing base 9 on the side close to the embankment is higher than the height on the side away from the embankment. A railing 10 is arranged on the upper surface of the railing base 9 along the length direction of the embankment, and the railing 10 is arranged perpendicular to the upper surface of the railing base 9.

[0062] A landscape walkway is arranged on the top surface of the cast-in-place concrete layer 8 close to the railing base 9 , and the landscape walkway is paved with natural stone strips 11 .

[0063] Beneficial effects of the above technical solution:

[0064] The bank protection structure for generating electricity using tidal energy described in the present invention utilizes prefabricated fixed feet and retaining walls on site for hoisting and assembly, and the construction of the bank protection structure is completed during the low tide period of the tide. There is no need to build a membrane bag sand cofferdam or a water-stop steel sheet pile cofferdam, and the construction speed is fast and the cost is low.

[0065] In one embodiment, Figure 3-6 As shown, the tidal energy power generation unit includes a swing mechanism, a transmission mechanism and a generator. The outer surface array of the prefabricated solid base layer 1 or the prefabricated retaining wall 2 is provided with a mounting groove 43. The swing mechanism and the transmission mechanism are arranged at intervals on the bottom surface of the mounting groove 43. The swing mechanism is connected to the power input shaft of the generator through the transmission mechanism.

[0066] Further, the swing mechanism includes a first link 14 and a second link 15, one end of which is rotatably connected to the bottom surface of the mounting groove 43, the other end of the first link 14 is hinged to one end of a swing rod 16, the other end of the swing rod 16 extends out of the mounting groove 43 and is provided with a blade 17, the other end of the second link 15 is hinged to one end of a fourth link 18, the other end of the fourth link 18 is hinged to one end of a fifth link 19, the other end of the fifth link 19 is hinged to the middle of the swing rod 16, one end of the third link 20 is rotatably connected to the first link 14, the other end of the third link 20 is rotatably connected to the second link 15, a push rod 26 is fixedly provided vertically downward in the middle of the swing rod 16, and the push rod 26 is located on the side of the fifth link 19 away from the blade 17;

[0067] The transmission mechanism includes a ring gear 21 and a transmission shaft 22 rotatably arranged in the center hole of the ring gear. A rotating rod 23 is fixedly arranged on one end of the transmission shaft 22 extending into the ring gear 21. A gear 24 is rotatably arranged on the end of the rotating rod 23 away from the transmission shaft 22. The gear 24 is meshed with the ring gear 21. A transmission rod 25 is fixedly arranged on the side of the gear 24 away from the rotating rod. The end of the transmission rod 25 away from the center of the gear 24 is rotatably connected to the push rod 26.

[0068] Furthermore, the blade 17 is hollow and streamlined, the horizontal cross-section of the blade 17 is rectangular, and the upper and lower surfaces of the blade 17 are streamlined.

[0069] Furthermore, one end of the transmission shaft 22 extending out of the ring gear 21 is dynamically connected to the power input shaft of the generator.

[0070] Furthermore, an overload clutch is provided between the transmission shaft 22 and the power input shaft of the generator.

[0071] The working principle of the above technical solution is:

[0072] Tidal energy can be used as a green energy source for power generation. By installing tidal power generation units on prefabricated fixed feet or retaining walls in inland rivers affected by tides, tidal energy can be effectively used for power generation.

[0073] In inland rivers affected by tides, in addition to tidal energy, river water will also fluctuate during its flow. Therefore, a swing mechanism can be used to absorb the energy brought by the fluctuations of water flow and tides, and then a transmission mechanism can be used to convert the swing into circular motion. The transmission shaft 22 of the transmission mechanism is connected to the power input shaft of the generator to enable the generator to generate electricity. An overrunning clutch is provided between the transmission shaft 22 and the power input shaft of the generator to prevent the transmission shaft 22 from reversing.

[0074] The tidal energy power generation unit is installed in the installation groove 43 on the outer surface of the prefabricated solid foot layer or the retaining wall. The other end of the swing rod 16 extends out of the installation groove 43 and is provided with a blade 17. The blade 17 is immersed in the water and swings up and down under the influence of the water wave. The blade 17 drives the swing rod 16 to swing. The swing rod 16 drives the gear 24 to rotate through the push rod 26 and the transmission rod 25. The gear 24 is meshed with the ring gear 21. The gear 24 rotates along the ring gear 21 and is driven to rotate the transmission shaft 22 through the rotating rod 23, thereby driving the generator to rotate to complete power generation.

[0075] The function of the first connection 14, the second connecting rod 15 and the third connecting rod 20 is to use the swing rod 16 to adapt to the change of the transmission rod position when the gear rotates. The ring gear and the generator are fixed on the prefabricated fixed feet. The generator can be a waterproof generator or a waterproof box can be used to install the generator.

[0076] The swing mechanism and the transmission mechanism are used to convert the swing into a circular motion. Since the swing rod is the power source, it is easy to get stuck when the traditional crank mechanism is used to convert the swing into a circular motion. For example, the ocean wave swing generator device disclosed in patent CN219622798U, because the fluctuation frequency of the waves or river water is not completely consistent with the swing frequency of the swing rod, when the guide rod 302 and the connecting rod 402 reach a vertical state and stop under the action of the waves, when the waves act on the guide rod 302 in the opposite direction, the force of the guide rod 302 on the connecting rod 402 is consistent with the length direction of the connecting rod. The guide rod cannot generate a force torque on the connecting rod 302, which will cause the crank mechanism to get stuck. The swing mechanism and the transmission mechanism are used, and the number of teeth of the gear and the gear ring is set according to the actual situation. This can prevent the torque of the swing rod 16 from passing through the axis of the transmission shaft 22, thereby avoiding the occurrence of a jam.

[0077] In order to ensure the stability of the swing mechanism and prevent the influence of water flow along the length direction of the embankment on the stability of the swing mechanism, two parallel sets of swing mechanisms can be arranged in the length direction of the embankment. The corresponding hinge positions between the two sets of swing mechanisms connect the hinge axes to increase the stability of the swing mechanism in the horizontal direction.

[0078] The blade 17 is hollow and streamlined, and the horizontal cross-section of the blade 17 is rectangular. The upper and lower surfaces of the blade 17 are streamlined. The upper and lower surfaces of the blade are used to receive the upper and lower impacts of tides or water currents. The swing rod 16 is used to swing, and the streamlined setting can reduce the impact of horizontally flowing water currents.

[0079] In one embodiment, Figure 7-10As shown, four lifting rings 27 are arranged in a rectangular array on the top surface of the prefabricated fixed foot, and the lifting rings 27 are used for lifting the prefabricated fixed foot. A locking hole 28 is arranged at a position corresponding to the lifting ring 27 on the bottom surface of the prefabricated fixed foot, and a locking mechanism is arranged in the locking hole. The locking mechanism includes a horizontally arranged rotating shaft 29, and the rotating shaft 29 is rotatably arranged in the locking hole 28. A locking hook 30 is fixedly connected to the rotating shaft 29, and the locking hook 30 is arranged vertically. The lower end of the locking hook 30 is an inclined surface, and the back of the locking hook 30 is fixedly connected to one end of a spring 31, and the other end of the spring 31 is fixedly connected to the inner wall of the locking hole 28. The bottom surface of the locking hole 28 is located at the locking hook A first rack hole 32 is provided on the side of 30 away from the spring 31, a first rack 33 is slidably arranged in the first rack hole 32, the first rack 33 extends into the gear groove 34, a transmission gear 35 is rotatably arranged in the gear groove 34, a second rack hole 36 is provided on the bottom surface of the gear groove 34, a second rack 37 is slidably arranged in the second rack hole 36, the second rack 37 is meshed with the gear 35, the second rack 37 is located at the rear side of the first rack 32, a slot 38 is provided on the upper surface of one end of the second rack 37 extending out of the gear groove 34, and the side wall of the slot 38 on the side away from the bottom surface of the gear groove 34 is vertically arranged;

[0080] The gear groove 34 is opened on the right side surface of the prefabricated fixed foot, and a connecting groove 39 is opened on the left side surface of the prefabricated fixed foot at a position opposite to the gear groove 34. A groove 40 is opened on the upper side wall of the connecting groove 39. A latch tongue 41 is slidably arranged in the groove 40. The upper end surface of the latch tongue 41 is fixedly connected to one end of a compression spring 42, and the other end of the compression spring 42 is fixedly connected to the bottom surface of the groove 40.

[0081] The working principle of the above technical solution is as follows: during the installation of the prefabricated fixed feet, when the upper prefabricated fixed feet are spliced ​​to the lower prefabricated fixed feet, the lifting ring 27 is aligned with the locking hole 28. When the lifting ring 27 enters the locking hole 28, it contacts the inclined surface of the lower end of the locking hook 30, so that the locking hook 30 squeezes the spring 31, and the locking hook 30 rotates with the rotating shaft 29. When the lifting ring 27 exceeds the position of the hook head of the locking hook 30, the locking hook rotates toward the lifting ring under the action of the spring, and the hook head of the locking hook hooks the lifting ring, so that the upper and lower layers of the prefabricated fixed feet are connected together. The initial state of the locking hook 30 is a vertical state. In the initial state, the lower end surface of the first rack 33 and the bottom surface of the prefabricated fixed foot are at the same level. In the plane, when the lifting ring enters the locking hole, the top end of the lifting ring squeezes the first rack, and the first rack is used to move upward, and the first rack 33 drives the transmission gear 35 to rotate, and the transmission gear 35 drives the first rack 37 to extend out of the gear slot 34 and enter the connecting slot 39, and the second rack 37 squeezes the arc part of the latch 41, so that the latch 41 squeezes the compression spring 42 and moves upward, and when the slot 38 on the second rack 37 is aligned with the latch 41, the latch 41 is engaged in the slot 38 under the action of the compression spring, so that the hoisted prefabricated fixed foot is connected to the prefabricated fixed foot that has been hoisted on the right side. At this time, the locking hook of the hoisted prefabricated fixed foot just hooks the lifting ring of the prefabricated fixed foot that has been hoisted below.

[0082] By using the above technical solution, the upper and lower layers of the spliced ​​prefabricated solid feet and the left and right adjacent prefabricated solid feet are connected into a whole, which increases the strength and stability of the entire embankment protection structure and increases its service life. It can also increase the stability of the prefabricated solid feet after hoisting during the construction process when they are washed by the tide due to unfinished subsequent construction.
