Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic gates, and in particular to a new type of gravity type transverse tide - blocking gate structure. Background Art

[0002] A tide - blocking gate is a sluice built in coastal areas or near river mouths for tide - blocking, fresh - water storage, flood - discharging, and waterlogging - draining. When the tide is rising, the gate is closed to prevent the back - flow of the tide into the river, store fresh water in the inland river, and meet the needs of water diversion, shipping, etc. When the tide is ebbing, the tide level is lower than the river level, and the gate is opened to discharge floods, drain waterlogging, and scour silt.

[0003] As a country with a long coastline, China has a large number of rivers flowing into the sea, and both sides of the rivers are basically important cities with low - lying terrain. With the continuous rise of the global sea level and the increasing ground settlement, the invasion of storm surges seriously affects the lives and property safety of people in the areas around the river channels. Therefore, it is urgent to build tide - blocking gates at the river mouths flowing into the sea.

[0004] The horizontal sliding gate is one of the common types of tide - blocking gates. It has the advantages of bidirectional water - blocking, no obstruction to navigation, good maintenance conditions, etc. Generally, the horizontal sliding gate is suitable for static water opening and closing. When blocking water, the force support of the gate body depends on the two - side pier heads, but the span of the gate is limited. At present, in the existing water conservancy projects at home and abroad, the span of the horizontal sliding gate is usually not more than 50m, which is relatively small. And the cross - section of the horizontal sliding gate body is usually a closed rectangle, with poor structural strength and general landscape effect.

[0005] Therefore, through beneficial exploration and research, the applicant has found a solution to the above problems, and the technical solution to be introduced below is generated under this background. Summary of the Invention

[0006] The technical problem to be solved by the present invention is: to provide a new type of gravity type transverse tide - blocking gate structure that can achieve large - span tide - blocking, has a novel and beautiful structure, and good structural stability in view of the deficiencies of the prior art.

[0007] The technical problem to be solved by the present invention can be realized by adopting the following technical solutions:

[0008] A new type of gravity type transverse tide - blocking gate structure, comprising:

[0009] A floating - box - type gate bottom plate;

[0010] A triangular truss fixedly arranged on the floating - box - type gate bottom plate and extending along the length direction of the floating - box - type gate bottom plate;

[0011] A number of lower flow - blocking floating boxes arranged at intervals along the length direction on the floating - box - type gate bottom plate and located inside the triangular truss;

[0012] A number of flow-through gates are arranged at intervals along the length direction on the triangular truss and are respectively located between two adjacent lower flow-blocking floating boxes; and

[0013] A water filling and draining system is arranged inside the triangular truss for respectively controlling the water filling and draining of the bottom plate of the floating box type gate and / or each lower flow-blocking floating box;

[0014] When tide protection is required, the water in the bottom plate of the floating box type gate and each lower flow-blocking floating box is emptied through the water filling and draining system, and at the same time, each flow-through gate is opened. The tide protection gate is towed from the gate chamber to a predetermined tide protection position under the push of the opening and closing equipment; at this time, the water filling and draining system is used to fill water into the bottom plate of the floating box type gate and each lower flow-blocking floating box to increase the self-weight of the tide protection gate, so that the tide protection gate sinks to the river bottom surface, and finally the flow-through gates are closed in sequence.

[0015] In a preferred embodiment of the present invention, the bottom plate of the floating box type gate is spliced by a number of cavity type steel structure small floating boxes.

[0016] In a preferred embodiment of the present invention, the triangular truss includes:

[0017] A number of regular triangular steel brackets are fixedly arranged at intervals along the length direction on the bottom plate of the floating box type gate;

[0018] A front additional triangular steel bracket and a rear additional triangular steel bracket are symmetrically and fixedly arranged on the upper parts of the front and rear sides of the regular triangular steel bracket; and

[0019] A first connecting cross beam is arranged between two adjacent regular triangular steel brackets for fixedly connecting the two adjacent regular triangular steel brackets;

[0020] A second connecting cross beam is arranged between two adjacent front additional triangular steel brackets for fixedly connecting the two adjacent front additional triangular steel brackets; and

[0021] A third connecting cross beam is arranged between two adjacent rear additional triangular steel brackets for fixedly connecting the two adjacent rear additional triangular steel brackets.

[0022] In a preferred embodiment of the present invention, each regular triangular steel bracket is formed by enclosing a front waist side steel bar and a rear waist side steel bar. The upper ends of the front waist side steel bar and the rear waist side steel bar are connected to each other, and their lower ends are respectively fixedly connected to the bottom plate of the floating box type gate. An equilateral triangle is formed by enclosing between the front waist side steel bar, the rear waist side steel bar and the bottom plate of the floating box type gate. The two ends of each first connecting cross beam are respectively connected to the vertex positions of two adjacent regular triangular steel brackets.

[0023] In a preferred embodiment of the present invention, an inverted equilateral triangular steel bracket is arranged inside each regular triangular steel bracket. The bottom angles of the inverted equilateral triangular steel bracket are fixedly connected to the top surface of the pontoon gate bottom plate, and its two top angles are respectively fixedly connected to the front waist edge steel bar and the rear waist edge steel bar.

[0024] In a preferred embodiment of the present invention, a connecting platform is constructed between the top edges of every two adjacent inverted equilateral triangular steel brackets. After a number of connecting platforms are spliced along the length direction, a through-length connecting corridor is formed.

[0025] In a preferred embodiment of the present invention, each front additional triangular steel bracket is enclosed by a front upper waist edge steel bar and a front lower waist edge steel bar. One ends of the front upper waist edge steel bar and the front lower waist edge steel bar are connected to each other, and the other ends are respectively connected to the top and middle parts of the front waist edge steel bar. Both ends of each second connecting cross beam are respectively connected to the top angle positions of two adjacent front additional triangular steel brackets.

[0026] In a preferred embodiment of the present invention, a front operation platform support cross beam is horizontally arranged inside each front additional triangular steel bracket. Both ends of the front operation platform support cross beam are respectively connected to the front lower waist edge steel bar and the front waist edge steel bar. A front operation platform is constructed between the front operation platform support cross beams of every two adjacent front additional triangular steel brackets. After a number of front operation platforms are spliced along the length direction, a front through-length operation corridor is formed.

[0027] In a preferred embodiment of the present invention, each rear additional triangular steel bracket is enclosed by a rear upper waist edge steel bar and a rear lower waist edge steel bar. One ends of the rear upper waist edge steel bar and the rear lower waist edge steel bar are connected to each other, and the other ends are respectively connected to the top and middle parts of the rear waist edge steel bar. Both ends of each third connecting cross beam are respectively connected to the top angle positions of two adjacent rear additional triangular steel brackets.

[0028] In a preferred embodiment of the present invention, a rear operation platform support cross beam is horizontally arranged inside each rear additional triangular steel bracket. Both ends of the rear operation platform support cross beam are respectively connected to the rear lower waist edge steel bar and the rear waist edge steel bar. A rear operation platform is constructed between the rear operation platform support cross beams of every two adjacent rear additional triangular steel brackets. After a number of rear operation platforms are spliced along the length direction, a rear through-length operation corridor is formed.

[0029] In a preferred embodiment of the present invention, each lower flow-blocking pontoon is located between two adjacent regular triangular steel brackets. Its outer contour is a cavity-type steel structure, and a steel structure support member is arranged inside it.

[0030] In a preferred embodiment of the present invention, the overflow gate is composed of a number of overflow small gates arranged side by side in the length direction, and each overflow small gate is located between two adjacent regular triangular steel supports.

[0031] In a preferred embodiment of the present invention, each overflow small gate includes:

[0032] A downward-folding door body, which is located between two adjacent regular triangular steel supports, and the two ends of its lower side are correspondingly hinged to the middle of the front waist edge steel bars of the two adjacent regular triangular steel supports through hinge pieces;

[0033] A first fixed pulley, which is fixedly installed on the corresponding second connecting cross beam; and

[0034] A first winch hoist, which is installed between two adjacent front additional triangular steel supports, and the steel wire rope released by it bypasses the first fixed pulley and then is connected to the upper side edge of the downward-folding door body.

[0035] In a preferred embodiment of the present invention, each overflow small gate includes:

[0036] A downward-sliding door body, which is located between two adjacent regular triangular steel supports and abuts against the outer side surfaces of the front waist edge steel bars of the two adjacent regular triangular steel supports;

[0037] A second fixed pulley, which is fixedly installed on the corresponding first connecting cross beam; and

[0038] A second winch hoist, which is installed between two adjacent rear additional triangular steel supports, and the steel wire rope released by it bypasses the second fixed pulley and then is connected to the upper side edge of the downward-sliding door body.

[0039] Due to the adoption of the above technical solutions, the beneficial effects of the present invention are as follows:

[0040] 1. The present invention optimizes the cross-section of the traditional horizontally pulled door body, improves the rectangular door body cross-section into a triangular door body cross-section. The stress stability of the triangular door body is better, and the width of the gate increases with the increase of water depth, and the door body cross-section is more scientific and reasonable, which is in line with the stress characteristics of the structure.

[0041] 2. After the cross-section of the gate door body of the present invention is improved, the overall stress mode of the horizontally pulled door is correspondingly adjusted. When the traditional horizontally pulled door blocks water, the stress support of the door body relies on the two side piers, forming a simply supported beam stress mode, and the span of the gate is limited by this and should not be too large; in addition, since the triangular door body cross-section is not suitable for bearing large bending moments, and at the same time to meet the needs of large-span tide blocking, the horizontally pulled door is designed as a gravity type.

[0042] 3. In order to avoid excessive opening and closing force required for the gravity type horizontal sliding gate, floating boxes are provided at the bottom of the triangle and part of the gate body. During the movement of the gate, due to the buoyancy provided by the floating boxes, most of the gravity is balanced. When tide protection is needed, water is filled into the floating boxes to increase the self-weight of the gate, and the conversion between buoyancy and gravity is ingeniously utilized throughout the process.

[0043] 4. Since the process of moving the tide gate from the gate chamber to the middle of the river channel to block water generally takes 1 to 2 hours. During this period, as the tide rises on the outer sea side, if a closed gate body structure is adopted, a certain water head difference will be generated between the upstream and downstream of the tide gate, which is not conducive to the stable operation of the gate (because at this time, the buoyancy balances most of the gravity and the gate is relatively light). Therefore, in the present invention, flow-through channels are provided at most of the gate body (except for the gate body where the floating box is provided as described above), to ensure the flow-through capacity of the river channel, thereby avoiding excessive water head difference on both sides of the gate.

[0044] 5. The present invention integrates the building with the traditional hydraulic gate structure, endowing the gate with more building space and functions. The structure of the gate is simple and the force is reasonable, demonstrating the structural beauty in architectural art. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below with reference to specific drawings. Embodiment

[0057] See Figures 1 to 3 , what is shown in the figure is a new type of gravity-type transverse tide-blocking sluice structure, including a floating box-type gate bottom plate 100, a triangular truss 200, a number of lower flow-blocking floating boxes 300, a number of over-current gates 400, and a filling and drainage system (not shown in the figure)

[0058] The floating box-type gate bottom plate 100 is spliced by a number of cavity-type steel structure small floating boxes 110, and its interior can be filled with and drained of water. During the movement of the gate, after draining water, it serves as a floating box to balance part of the gate gravity, and during the tide-blocking state, it fills with water to increase the self-weight of the gate.

[0059] The triangular truss 200 is fixedly arranged on the floating box-type gate bottom plate 100 and extends along the length direction of the floating box-type gate bottom plate 100. The floating box-type gate bottom plate 100 serves as the bottom part of the triangular truss 200. The main stress section of the triangular truss 200 is an equilateral triangle section, giving play to the advantages of the triangular structure being stable and not easily deformed. Specifically, the triangular truss 200 includes a number of equilateral triangular steel brackets 210, a number of front additional triangular steel brackets 220, a number of rear additional triangular steel brackets 230, a number of first connecting crossbeams 240, a number of second connecting crossbeams 250, and a number of third connecting crossbeams 260.

[0060] A number of equilateral triangular steel brackets 210 are fixedly arranged on the floating box-type gate bottom plate 100 at intervals along the length direction. Each equilateral triangular steel bracket 210 is formed by enclosing a front waist edge steel bar 211 and a rear waist edge steel bar 212. The upper ends of the front waist edge steel bar 211 and the rear waist edge steel bar 212 are connected to each other, and their lower ends are respectively fixedly connected to the floating box-type gate bottom plate 100. An equilateral triangle is formed by enclosing between the front waist edge steel bar 211, the rear waist edge steel bar 212 and the floating box-type gate bottom plate 100.

[0061] Inside each regular triangular steel bracket 210, there is an inverted equilateral triangular steel bracket 213. The base angles of the inverted equilateral triangular steel bracket 213 are fixedly connected to the top surface of the pontoon gate bottom plate 100, and its two vertex angles are respectively fixedly connected to the front waist side steel bar 211 and the rear waist side steel bar 212 of the triangular steel bracket 210. At the same time, a connecting platform 214 is constructed between the top edges of every two adjacent inverted equilateral triangular steel brackets 213. After a number of connecting platforms 214 are spliced along the length direction, a through-length connecting corridor is formed.

[0062] The front waist side steel bar 211 and the rear waist side steel bar 212 of the regular triangular steel bracket 210 adopt large welded I-shaped steel structures and bear water pressure when retaining water. Since the regular triangular steel bracket 210 is subjected to greater forces when tide-proofing, an inverted equilateral triangular steel bracket 213 is arranged inside it to enhance the force-bearing capacity of the regular triangular steel bracket 210. In addition, a through-length connecting corridor is arranged between the top edges of two adjacent inverted triangles, which together with the two waist sides of the regular triangular steel bracket 210 form an internal triangular space that can be used as a building space for arranging equipment and also serves as a connecting structure between two adjacent regular triangular steel brackets 210.

[0063] The front additional triangular steel bracket 220 and the rear additional triangular steel bracket 230 are symmetrically and fixedly arranged on the upper parts of the front and rear sides of the corresponding regular triangular steel bracket 210. One side of the front additional triangular steel bracket 220 and the rear additional triangular steel bracket 230 is the waist side of the regular triangular steel bracket 210.

[0064] Each front additional triangular steel bracket 220 is enclosed by a front upper waist side steel bar 221 and a front lower waist side steel bar 222. One end of the front upper waist side steel bar 221 and the front lower waist side steel bar 222 are connected to each other, and the other ends are respectively connected to the top and middle parts of the front waist side steel bar 211 of the regular triangular steel bracket 210. That is to say, one side of the front additional triangular steel bracket 220 is the waist side of the regular triangular steel bracket 210. The front upper waist side steel bar 221 and the front lower waist side steel bar 222 of the front additional triangular steel bracket 220 adopt welded I-shaped steel structures to improve the overall structural strength.

[0065] A front operation platform support cross beam 223 is horizontally arranged inside each front additional triangular steel bracket 220. The two ends of the front operation platform support cross beam 223 are respectively connected to the front lower waist side steel bar 222 and the front waist side steel bar 211. A front operation platform 224 is constructed between the front operation platform support cross beams 211 of every two adjacent front additional triangular steel brackets 220. After a number of front operation platforms 224 are spliced along the length direction, a front through-length operation corridor is formed. The front through-length operation corridor can be used to arrange a hoist and can also be used as a lookout platform. At the same time, this corridor is also a connecting structure between two adjacent front additional triangular steel brackets 220.

[0066] Each rear additional triangular steel bracket 230 is formed by enclosing a rear upper waist edge steel bar 231 and a rear lower waist edge steel bar 232. One ends of the rear upper waist edge steel bar 231 and the rear lower waist edge steel bar 232 are connected to each other, and the other ends are respectively connected to the top and middle parts of the rear waist edge steel bar 212 of the regular triangular steel bracket 210. That is to say, one side of the rear additional triangular steel bracket 230 is a waist edge of the regular triangular steel bracket 210. The rear upper waist edge steel bar 231 and the rear lower waist edge steel bar 232 of the rear additional triangular steel bracket 230 adopt a welded I-beam structure to improve the overall structural strength.

[0067] A rear operation platform support cross beam 233 is horizontally arranged inside each rear additional triangular steel bracket 230. Two ends of the rear operation platform support cross beam 233 are respectively connected to the rear lower waist edge steel bar 232 and the rear waist edge steel bar 212. A rear operation platform 234 is constructed between the rear operation platform support cross beams 233 of every two adjacent rear additional triangular steel brackets 230. A number of rear operation platforms 234 are spliced along the length direction to form a rear through-length operation corridor. The rear through-length operation corridor can be used to arrange a hoisting winch, or can be used as a lookout platform. At the same time, this corridor is also a connection structure between adjacent rear additional triangular steel brackets 230.

[0068] The first connection cross beam 240 is arranged between two adjacent regular triangular steel brackets 210, and is used for fixedly connecting the two adjacent regular triangular steel brackets 210. Specifically, two ends of each first connection cross beam 240 are respectively connected to the top angle positions of the two adjacent regular triangular steel brackets 210.

[0069] The second connection cross beam 250 is arranged between two adjacent front additional triangular steel brackets 220, and is used for fixedly connecting the two adjacent front additional triangular steel brackets 220. Specifically, two ends of each second connection cross beam 250 are respectively connected to the top angle positions of the two adjacent front additional triangular steel brackets 220.

[0070] The third connection cross beam 260 is arranged between two adjacent rear additional triangular steel brackets 230, and is used for fixedly connecting the two adjacent rear additional triangular steel brackets 230. Specifically, two ends of each third connection cross beam 260 are respectively connected to the top angle positions of the two adjacent rear additional triangular steel brackets 230.

[0071] The triangular truss 200 is composed of multiple triangles, with good structural stability and clear force transmission. Since each regular triangular steel bracket 210 is independent, the adjacent regular triangular steel brackets 210 are connected by the floating caisson gate bottom plate 100 arranged longitudinally, the connecting platform 214, the front operation platform 224, the rear operation platform 224, the first connecting cross beam 240, the second connecting cross beam 250, and the third connecting cross beam 260, so that each regular triangular steel bracket 210 is connected into a whole and bears force together, improving the overall structural strength and stability.

[0072] See Figure 4 and in combination with Figure 3 , several lower flow-blocking floating caissons 300 are arranged at intervals along the length direction on the floating caisson gate bottom plate 100 and are located inside the triangular truss 200, which are used to balance the gravity of the gate. Specifically, each lower flow-blocking floating caisson 300 is located between two adjacent regular triangular steel brackets 210, and its outer contour is a cavity-type steel structure, and a steel structure support member is arranged inside to ensure that the lower flow-blocking floating caisson 300 will not be damaged under water pressure.

[0073] Several flow-through gates 400 are arranged at intervals along the length direction on the triangular truss 200 and are respectively located between two adjacent lower flow-blocking floating caissons 300. Specifically, the flow-through gate 400 is composed of several flow-through small gates 410 arranged side by side along the length direction, and each flow-through small gate 410 is located between two adjacent regular triangular steel brackets 210. In this embodiment, the flow-through small gate 410 adopts a downward-turning door structure, which includes a downward-turning door body 411, a fixed pulley 412, and a hoisting winch 413.

[0074] The downward-turning door body 411 is located between two adjacent regular triangular steel brackets 210, and the two ends of its lower side are correspondingly hinged to the middle of the front waist edge steel bars 211 of the two adjacent regular triangular steel brackets 210 through hinge pieces. The fixed pulley 412 is fixedly installed on the corresponding second connecting cross beam 250. The hoisting winch 413 is installed between two adjacent front additional triangular steel brackets 220, and the steel wire rope 4131 released by it bypasses the fixed pulley 412 and is connected to the upper side edge of the downward-turning door body 411. The hoisting winch 413 can be installed on the front operation platform 224 constructed between two adjacent front additional triangular steel brackets 220.

[0075] See Figure 5 and Figure 6, when the left side is the tide-blocking side, one side of the front additional triangular steel bracket 220 can serve as the gate reservoir for the flap gate body 411 of the small flow-through gate 410. In the non-tide-blocking state, the gate is fixed to the waist side of the front additional triangular steel bracket 220 through the hoist 413 and the fixed pulley 412. During tide blocking, the flap gate body 411 is lowered through the hoist 413 and the fixed pulley 412 to form a water-blocking surface. The flap gate body 411 slowly falls on the waist side of the regular triangular steel bracket 210 under its own weight. When the water level on the tide-blocking side rises, the weight of the water can serve as a counterweight, pressing the gate tightly against the waist side of the regular triangular steel bracket 210, which is beneficial to the closure and water stoppage of the gate.

[0076] The filling and draining system is arranged inside the triangular truss 200, and it is used to respectively control the filling and draining of the floating box type gate bottom plate 100 and / or each lower flow-blocking floating box 300. The filling and draining system is a conventional design in this field and will not be elaborated here.

[0077] The operation process of the new gravity type transverse tide-blocking sluice structure in this embodiment is as follows:

[0078] 1. Drain the water bodies inside the floating box type gate bottom plate 100 and each lower flow-blocking floating box 200 through the filling and draining system, and open each flow-through gate 400 to ensure that water can flow through the gate. The tide-blocking sluice is towed from the gate reservoir to the predetermined tide-blocking position (the center of the river channel) under the push of the opening and closing equipment;

[0079] 2. When the tide-blocking sluice reaches the predetermined tide-blocking position, fill the floating box type gate bottom plate 100 and each lower flow-blocking floating box 200 with water through the filling and draining system to increase the self-weight of the tide-blocking sluice, so that the tide-blocking sluice sinks to the river bottom surface;

[0080] 3. Close the flow-through gates 400 in sequence, and the tide-blocking sluice starts to block the tide; when closing the flow-through gates 400, assuming there are 7 gates, to ensure the stability of the water flow, they are closed at intervals, that is, first close gates 1, 3, 5, and 7, and then close gates 2, 4, and 6.

[0081] 4. After completing the tide blocking, open the flow-through gates 400 to allow water to flow through, also using interval opening.

[0082] 5. Drain the water bodies inside the floating box type gate bottom plate 100 and each lower flow-blocking floating box 200 through the filling and draining system to make the tide-blocking sluice float, and then under the push of the opening and closing equipment, tow the tide-blocking sluice back to the gate reservoir. Embodiment

[0083] The new gravity type transverse tide-blocking sluice structure in this embodiment is substantially the same as the new gravity type transverse tide-blocking sluice structure in Embodiment 1, and the difference lies in that: the small flow-through gate 410a in the flow-through gate 400a adopts a sliding-down gate type. Specifically, refer to Figures 7 to 10, each overcurrent small gate 410a includes a sliding gate body 411a, a fixed pulley 412a, and a hoisting winch 413a.

[0084] The sliding gate body 411a is located between two adjacent regular triangular steel supports 210a and abuts against the outer side surfaces of the front waist side steel bars 211a of the two adjacent regular triangular steel supports 210a. The fixed pulley 412a is fixedly installed on the corresponding first connecting cross beam 240a. The hoisting winch 413a is installed between two adjacent rear additional triangular steel supports 230a, and the steel wire rope 4131a released by it bypasses the fixed pulley 412a and is connected to the upper side edge of the sliding gate body 411a. The hoisting winch 413 can be installed on the rear operation platform 234a constructed between two adjacent rear additional triangular steel supports 230.

[0085] When the left side is the tide-blocking side, the front waist side steel bar 211a of the regular triangular steel support 210a can serve as the gate reservoir of the sliding gate body 411a. In the non-tide-blocking state, the gate is fixed and docked at the upper part of the front waist side steel bar 211a of the regular triangular steel support 210a through the hoisting winch 413a and the fixed pulley 412a. When blocking the tide, the sliding gate body 411a is lowered to form a water-blocking surface. The sliding gate body 411a slowly slides down along the front waist side steel bar 211a of the regular triangular steel support 210a under its own weight. When the water level on the tide-blocking side rises, the water weight can serve as a counterweight to tightly attach the sliding gate body 411a to the front waist side steel bar 211a of the regular triangular steel support 210a, which is beneficial to the closing and water stopping of the gate.
