Description

Technical Field

[0001] The utility model relates to the technical field of flood control devices, in particular to a conveniently assembled and disassembled flood control sub-dike and components thereof. Background Art

[0002] The flood control sub-dike is a temporary dam structure built to prevent floods from overflowing. It mainly refers to the panel dam principle in water conservancy projects, and uses multiple angle frames, beams and panel structures to connect to form a rigid sub-dike body. Among them, the panel structure of the flood control sub-dike directly blocks the impact of floods, and the connection between the beams and the panel structure needs to have sufficient strength and durability to withstand the pressure and impact of floods. In addition, before the flood comes, people need to assemble the flood control sub-dike quickly. Therefore, the assembly efficiency and connection reliability of the flood control sub-dike are particularly important for the implementation of flood control and disaster prevention operations.

[0003] In the prior art, a Chinese patent with publication number CN 213653356U provides a flood wall for water conservancy projects, including a triangular support frame, a U-shaped block, a connector, a support column and a flood control board. The flood wall for water conservancy projects uses a triangular support frame as a bracket, so that the flood control board is installed on it, and the support column is used to support the two triangular support frames to form a flood wall. The flood wall for water conservancy projects adopts a foldable tripod, which provides convenience for the assembly of flood control sub-dikes to a certain extent. However, in the actual construction process of the flood wall for water conservancy projects, the folding and opening of the tripod requires multiple people to operate, and there are difficulties in assembly. In addition, the connection between the support column and the triangular support frame of the flood wall for water conservancy projects is fixed by bolts, which makes it difficult to realize the rapid disassembly and assembly of the flood control sub-dike. The prior art also uses quick connectors similar to gas circuits or liquid circuits, but the sub-dike frame structure built is not stable, and the connection is prone to shaking, which is difficult to meet the complex and changeable on-site requirements of flood control.

[0004] Therefore, in view of the problems existing in the prior art, there is an urgent need to provide a flood control sub-dike and its components that are easy to assemble and disassemble. Summary of the invention

[0005] In order to overcome the problems existing in the above-mentioned prior art, the utility model proposes a flood control sub-dike and its components which are convenient to assemble and disassemble, so as to improve the assembly efficiency and connection firmness of the flood control sub-dike.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A flood-proof sub-embankment that is convenient to assemble and disassemble comprises a fixing frame and a baffle plate arranged on the fixing frame; the fixing frame comprises two supporting frames arranged opposite to each other, and a plurality of cross beams are detachably connected between the two supporting frames;

[0008] The crossbeam is provided with a plurality of connecting fasteners, and the baffle is connected to the crossbeam through the connecting fasteners; at least one group of quick-release fasteners is provided between the end of the crossbeam and the side wall of the support frame; the quick-release fasteners include a mother buckle and a child buckle; the mother buckle is provided with a first opening and a second opening that are interconnected; wherein the width dimension of the first opening is greater than the width dimension of the second opening; the child buckle is provided with a buckling portion, and the buckling portion is adapted to the opening shape of the second opening; a flexible stopper is provided at the connection between the first opening and the second opening; the buckling portion of the child buckle extends into the first opening, acts on the stopper to deform it, and then snaps into the second opening, and is matched with the second opening for connection.

[0009] In the utility model, by arranging a first hole and a second hole that are interconnected on the mother buckle, the sub-buckle is inserted from the first hole into the second hole, thereby realizing rapid disassembly and assembly of the crossbeam and the support frame. The assembly and disassembly can be completed by a single person, and the operation is convenient and reliable, which meets the requirements of high-efficiency assembly operations of flood-control sub-dikes. A flexible stopper is provided at the connection between the first hole and the second hole, and the sub-buckle is constrained in the second hole by the stopper to avoid accidental disengagement, thereby ensuring reliable cooperation between the sub-buckle and the mother buckle and improving the firmness of the flood-control sub-dike construction.

[0010] As a further improvement of the above scheme, the support frame is formed by multiple side beams connected end to end in sequence, and adjacent side beams are connected by a corner joint; the corner joint includes a corner base, each of the two ends of the corner base is provided with a clamping part, and the corner base is fixedly connected to the corresponding side beam through the two clamping parts.

[0011] The corner base is the core part of the connection. It is tightly fixed to the side beams through the clamping parts at both ends to form a stable frame structure that can effectively resist deformation under external forces. In addition, compared with the traditional welding connection, the design of the clamping part provides a more secure and easy-to-install connection method. The fixed connection between the clamping part and the side beam can ensure that the connection will not loosen or break, thereby ensuring the connection strength of the entire support frame. When a side beam or corner joint is damaged, only the corresponding part needs to be replaced, without replacing the entire support frame, thereby reducing maintenance costs and time.

[0012] As a further improvement of the above scheme, the corner joint includes a left shell and a right shell, and the left shell and the right shell are mutually surrounded to form a space for accommodating the end of the side beam; a positioning pin is provided on the clamping part of the left shell and / or the right shell, and the side beam is correspondingly provided with a pin hole, and the side beam is positioned by cooperating with the positioning pin through the pin hole.

[0013] The corner joint is designed as a left shell and a right shell, making the assembly process easier. When the side beam needs to be connected to the corner joint, just put the end of the side beam into the space formed by the left shell and the right shell, and then use the positioning pin and the pin hole to quickly position it. This assembly method not only improves work efficiency, but also reduces the skill requirements for operators.

[0014] The cooperation between the positioning pin and the pin hole not only realizes quick positioning, but also makes the connection between the corner joint and the side beam more stable. Once the positioning pin is inserted into the pin hole, it can effectively prevent the side beam from sliding or rotating at the corner joint, thereby ensuring the overall stability and safety of the support frame.

[0015] As a further improvement of the above scheme, the stop parts are respectively provided on the opposite sides of the connection between the first opening and the second opening, and a passage for the sub-buckle to pass through is formed between the two stop parts; the two stop parts are deformed in opposite directions to shrink or expand the passage; when the stop parts are not subjected to the passing force of the sub-buckle, the minimum width dimension of the passage is smaller than the width dimension of the buckle, and the sub-buckle is confined in the second opening.

[0016] By providing stoppers on opposite sides of the connection between the first orifice and the second orifice, and forming a passage for the sub-buckle to pass through between the two stoppers, this design allows the sub-buckle to be guided and constrained by the stoppers on both sides when inserted, thereby increasing the locking stability between the sub-buckle and the mother buckle. This stability is particularly important for preventing the sub-buckle from accidentally disengaging during use. In addition, the two stoppers can deform in opposite directions, so that the size of the passage can be adaptively adjusted according to the size of the sub-buckle. This design not only enhances the compatibility between the sub-buckle and the mother buckle, but also further enhances the stability of the locking, because even if the sub-buckles are slightly different in size, they can be tightly locked through the deformation of the stoppers.

[0017] As a further improvement of the above scheme, the female buckle includes a base, which has a through groove; a stepped ring platform is provided in the through groove, and the stepped ring platform extends along the circumferential inner wall of the through groove; the outer side of the stepped ring platform is connected to the inner wall of the through groove, and the inner side of the stepped ring platform shrinks inward to naturally form various openings; or, the inner side of the stepped ring platform is combined with the inner wall of the through groove to form various openings.

[0018] The stepped ring extends along the circumferential inner wall of the through groove. This structure can effectively disperse and transfer the load, reduce stress concentration, and thus improve the stability and reliability of the female buckle structure. At the same time, since the stepped ring extends along the circumferential inner wall of the through groove to form various openings, the sub-buckle can be quickly positioned to the correct position during insertion, reducing the adjustment and correction time during the insertion process and improving the connection efficiency.

[0019] As a further improvement of the above scheme, the stepped ring platform is provided with avoidance openings on both sides of the passage, and the avoidance openings are located on the side close to the inner wall of the through groove; the stepped ring platform between the passage and the avoidance openings on both sides forms the stopping part; the avoidance openings provide avoidance space for the deformation of the stopping part.

[0020] Since the avoidance opening provides an avoidance space for the deformation of the stopper, the resistance encountered by the sub-buckle during the insertion process is reduced. The design of the avoidance opening also enables the sub-buckle to pass through the passage opening more smoothly during the insertion process, further improving the convenience of the clamping.

[0021] As a further improvement of the above scheme, in the penetration direction of the through groove, the stepped ring platform divides the through groove into a first concave cavity and a second concave cavity; the sub-buckle includes a first shaft buckle and a second shaft buckle arranged along its axial direction, and the radial recess between the two forms the buckling portion; the first concave cavity and the second concave cavity respectively correspond to the first shaft buckle and the second shaft buckle, so that the second orifice is engaged and connected with the buckling portion.

[0022] The first cavity and the second cavity are respectively matched with the first shaft buckle and the second shaft buckle. This design increases the contact area between the sub-buckle and the mother buckle. By increasing the contact area, the friction and stability between the connection points are enhanced, thereby improving the reliability of the connection. In addition, the first cavity and the second cavity cooperate with the first shaft buckle and the second shaft buckle, especially the snap-fit ​​connection with the buckle part, to form a stable locking structure. This structure can prevent the sub-buckle from accidentally disengaging when subjected to external force, thereby ensuring the durability and safety of the connection.

[0023] As a further improvement of the above scheme, the connecting fastener includes a square buckle, which is provided with a through ring, and the square buckle is sleeved on the crossbeam through the ring; at least one side of the square buckle protrudes outward to form a locking portion; the locking portion is fixedly connected to a stud, and the baffle is correspondingly provided with a through hole, and the stud is exposed through the through hole; it also includes a locking hand wheel, and the inner side of the locking hand wheel is provided with a sealing gasket; when the locking hand wheel and the stud are tightened, the inner side of the locking hand wheel presses against the baffle, and the sealing gasket is sealed on the surrounding side of the water-facing surface of the through hole.

[0024] The baffle can be connected to the beam by locking the locking handwheel and the stud, which is convenient and flexible to splice, meeting the requirements of high-efficiency operation in the actual flood control and prevention process; and because the connecting fasteners and the baffles are separately arranged, they do not need to be fixed on the baffles in advance, and the space occupied when stacked is small, and the connecting fasteners and other connecting accessories will not be deformed, which is convenient for packaging and transportation; at the same time, a sealing gasket is arranged on the inner side of the locking nut, and the sealing gasket is used to seal the surrounding side of the perforated water-facing surface to prevent floods from penetrating in, which has a good flood control and prevention effect.

[0025] As a further improvement of the above solution, the connecting fastener includes a mounting seat, and the mounting seat is fixedly connected to the baffle through a fastener; a clamping part is provided on each side of the mounting seat, and the connecting fastener clamps the baffle to the beam through the clamping part. The clamping part is quickly clamped on the corresponding beam, which is convenient to operate, low in cost, and conducive to production.

[0026] A conveniently assembled and disassembled flood-control sub-dike assembly, comprising the conveniently assembled and disassembled flood-control sub-dike as described above;

[0027] The support frame is formed by connecting multiple side beams end to end in sequence, and the cross beam and the side beams on the two support frames are laterally connected to form a fixed frame through quick-release fasteners; the quick-release fasteners are respectively provided on the opposite sides of each side beam, and the quick-release fasteners on both sides are mirror-imaged; the fixed frames are laterally connected in a row in sequence through the quick-release fasteners on the two outer end faces. Through the quick-release fasteners, the fixed frame can be laterally combined with the next fixed frame in a row. This connection method not only increases the stability of the flood control sub-dike assembly, but also can meet various complex installation environments and layout requirements according to the actual needs of the flood control and waterlogging relief site, greatly increasing the applicability of use.

[0028] Beneficial effects of the utility model:

[0029] (1) The structure is simple. By providing a first hole and a second hole that are interconnected on the female buckle, the female buckle is inserted into the second hole from the first hole to realize the rapid disassembly and assembly of the crossbeam and the support frame.

The operation is convenient and reliable, which meets the requirements of the high-efficiency assembly operation of the flood control sub-dike.

[0030] (2) A flexible stopper is provided at the connection point between the first hole and the second hole, and the sub-buckle is constrained in the second hole by the stopper to avoid accidental disengagement, thereby ensuring reliable cooperation between the sub-buckle and the mother buckle and improving the firmness of the flood control sub-dike.

[0063] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0064] Example 1

[0065] like Figure 1-Figure 13 As shown, a flood prevention sub-embankment that is convenient to assemble and disassemble comprises a fixing frame G1 and a baffle 3 arranged on the fixing frame G1; the baffle 3 is formed by sequentially splicing a plurality of baffle units 31; the fixing frame G1 comprises two oppositely arranged support frames G2, and a plurality of cross beams H1 are detachably connected between the two support frames G2;

[0066] In this embodiment, the support frame G2 is formed by three side beams S1 connected end to end in sequence, and the adjacent side beams S1 are connected by a corner joint 4; specifically, the side beams S1 can be made of 60mm×25mm aluminum alloy square tubes.

[0067] The corner joint 4 includes a corner base 41, and a clamping part 42 is provided at each end of the corner base 41. The corner base 41 is fixedly connected to the corresponding side beam S1 through the two clamping parts 42. The corner joint 4 can be made of PA plastic, and its outer contour can be provided with anti-slip texture, which can increase friction when pressed against the ground. The corner base 41 is the core part of the connection, and is tightly fixed to the side beam S1 through the clamping parts 42 at both ends to form a stable frame structure, which can effectively resist deformation under the action of external forces. In addition, compared with the traditional welding connection, the design of the clamping part 42 provides a more secure and easy-to-install connection method. The fixed connection between the clamping part 42 and the side beam S1 can ensure that the connection will not be loose or broken, thereby ensuring the connection strength of the entire support frame G2. When a side beam S1 or corner joint 4 is damaged, only the corresponding parts need to be replaced, and there is no need to replace the support frame G2 as a whole, thereby reducing maintenance costs and time.

[0068] In this embodiment, the support frame G2 is a triangular structure. To meet the needs of other places, the support frame G2 can also be configured as other polygons as long as it meets the requirements of stable mechanical support. Specifically, the crossbeam H1 can be a 30mm×30mm aluminum alloy square tube. Two crossbeams H1 are respectively provided at the bottom and side of the triangular support frame G2, and the baffle 3 is installed on the crossbeam H1 on the side of the triangular support frame G2. In order to prevent the sub-dike from retreating due to water pressure, U-shaped ground nails can be nailed into the bottom crossbeam H1 (soft ground), or sandbags can be pressed to position (hard ground), or curbstones can be relied on to prevent the sub-dike from retreating.

[0069] In this embodiment, the corner joint 4 includes a left shell 4a and a right shell 4b, and the left shell 4a and the right shell 4b are mutually surrounded to form a space for accommodating the end of the side beam S1; a positioning pin 43 is provided on the clamping portion 42 of the left shell 4a and / or the right shell 4b, and the side beam S1 is correspondingly provided with a pin hole S2, and the side beam S1 is positioned by the positioning pin 43 through the pin hole S2. The corner joint 4 is designed as a left shell 4a and a right shell 4b, which makes the assembly process easier. When the side beam S1 needs to be connected to the corner joint 4, it is only necessary to put the end of the side beam S1 into the space surrounded by the left shell 4a and the right shell 4b, and then quickly position it with the help of the positioning pin 43 and the pin hole S2. This assembly method not only improves work efficiency, but also reduces the skill requirements for operators. The cooperation of the positioning pin 43 and the pin hole S2 not only realizes rapid positioning, but also makes the connection between the corner joint 4 and the side beam S1 more stable. Once the positioning pin 43 is inserted into the pin hole S2, the side beam S1 can be effectively prevented from sliding or rotating at the corner joint 4, thereby ensuring the overall stability and safety of the support frame G2.

[0070] More specifically, reinforcing ribs are disposed at intervals in the corner base 41 of the left shell 4a and / or the right shell 4b to improve the structural strength of the entire support frame G2.

[0071] In the present embodiment, three connecting fasteners 2 are spaced apart on each cross beam H1, and the baffle 3 is connected to the cross beam H1 through the connecting fasteners 2; in the present embodiment, the connecting fastener 2 includes a square buckle 21, and the square buckle 21 is provided with a penetrating ring opening 22, and the square buckle 21 is sleeved on the cross beam H1 through the ring opening 22; at least one side of the square buckle 21 protrudes outward to form a locking portion 23; the locking portion 23 is fixedly connected with a stud 24, and the baffle 3 is correspondingly provided with a through hole 32, and the stud 24 is exposed through the through hole 32; it also includes a locking hand wheel 25, and the inner side of the locking hand wheel 25 is provided with a sealing gasket 26; when the locking hand wheel 25 and the stud 24 are tightened in cooperation, the inner side of the locking hand wheel 25 presses against the baffle 3, and the sealing gasket 26 is blocked on the peripheral side of the water-facing surface of the through hole 32. By locking the locking hand wheel 25 and the stud 24, the baffle 3 can be connected to the beam H1, which is convenient and flexible to splice, and meets the requirements of high-efficiency operation in the actual flood control process; and because the connecting fastener 2 and the baffle 3 are separately arranged, there is no need to pre-fix them on the baffle 3, and the space occupied is small when stacked, and the connecting fastener 2 and other connecting accessories will not be deformed, which is convenient for packaging and transportation; at the same time, a sealing gasket 26 is arranged on the inner side of the locking nut, and the sealing gasket 26 is used to seal the surrounding side of the water-facing surface of the perforation 32 to prevent floods from penetrating in, thereby having a good flood control and flood prevention effect.

[0072] Specifically, the locking portion 23 is provided with a flat first abutting surface 231 on one side facing the baffle 3; the stud 24 is perpendicular to the first abutting surface 231; when the locking hand wheel 25 cooperates with the stud 24 to be tightened, the baffle 3 is pressed against the first abutting surface 231. The side wall of the ring opening 22 of the square buckle 21 facing the baffle 3 is provided with a flat second abutting surface 232; the first abutting surface 231 is connected to or separated from the second abutting surface 232, and the two are on the same plane, and are in abutment with the back surface of the baffle 3 together.

[0073] The flat first abutting surface 231 and the second abutting surface 232 ensure gapless contact with the baffle 3, so that the pressure can be distributed more evenly during locking, thereby improving the stability of locking. It effectively prevents loosening or leakage caused by local stress concentration; in addition, the first abutting surface 231 and the second abutting surface 232 are connected or separated, but the two are on the same plane. This design further increases the contact area with the baffle 3, forming a continuous, large-area abutting surface. The large-area abutting surface can provide better support and stability, making it difficult for the baffle 3 to deform or displace when subjected to external forces.

[0074] At least one group of quick-release fasteners 1 is provided between the end of the crossbeam H1 and the side beam S1 of the support frame G2; the quick-release fasteners 1 include a mother buckle 11 and a child buckle 12; the mother buckle 11 is provided with a first opening 11a and a second opening 11b that are interconnected; wherein the width dimension of the first opening 11a is greater than the width dimension of the second opening 11b; the child buckle 12 is provided with a snap-fitting portion 121, and the snap-fitting portion 121 is adapted to the opening shape of the second opening 11b; a flexible stopper 13 is provided at the connection between the first opening 11a and the second opening 11b; the snap-fitting portion 121 of the child buckle 12 extends into the first opening 11a, acts on the stopper 13 to deform it, and then snaps into the second opening 11b, and is matched with the second opening 11b.

[0075] In this embodiment, the stop portions 13 are respectively provided on the opposite sides of the connection between the first hole 11a and the second hole 11b, and a passage T1 for the sub-buckle 12 to pass through is formed between the two stop portions 13; the two stop portions are deformed in opposite directions to shrink or expand the passage T1; when the stop portions 13 are not subjected to the passing force of the sub-buckle 12, the minimum width dimension of the passage T1 is smaller than the width dimension of the buckle 121, and the sub-buckle 12 is confined in the second hole 11b.

[0076] By providing a stopper 13 on opposite sides of the connection between the first orifice 11a and the second orifice 11b, and forming a passage T1 for the sub-button 12 to pass through between the two stoppers 13, this design allows the sub-button 12 to be guided and constrained by the stoppers 13 on both sides when inserted, thereby increasing the locking stability between the sub-button 12 and the mother buckle 11. This stability is particularly important for preventing the sub-button 12 from accidentally disengaging during use. In addition, the two stoppers can be deformed in opposite directions, so that the size of the passage T1 can be adaptively adjusted according to the size of the sub-button 12. This design not only enhances the compatibility between the sub-button 12 and the mother buckle 11, but also further enhances the stability of the locking, because even if the size of the sub-button 12 is slightly different, it can be tightly locked through the deformation of the stopper.

[0077] In this embodiment, the female buckle 11 includes a base 111, and the base 111 has a through slot 112; a stepped ring 113 is provided in the through slot 112, and the stepped ring 113 extends along the circumferential inner wall of the through slot 112; the outer side of the stepped ring 113 is connected to the inner wall of the through slot 112, and the inner side of the stepped ring 113 shrinks inward to naturally form each orifice; or, the inner side of the stepped ring 113 and the inner wall of the through slot 112 are combined to form each orifice. Specifically, the first orifice 11a is formed by the inner side of the stepped ring 113 and the inner wall of the through slot 112; the second orifice 11b is formed by the inner side of the stepped ring 113 shrinking inward.

[0078] The stepped annular platform 113 extends along the circumferential inner wall of the through groove 112. This structure can effectively disperse and transfer the load, reduce stress concentration, and thus improve the stability and reliability of the structure of the female buckle 11. At the same time, since the stepped annular platform 113 extends along the circumferential inner wall of the through groove 112 to form various openings, the sub-buckle 12 can be quickly positioned to the correct position during insertion, reducing the adjustment and correction time during the insertion process and improving the connection efficiency.

[0079] In this embodiment, the stepped ring platform 113 is provided with avoidance openings 114 on both sides of the passage T1, and the avoidance openings 114 are located on the side close to the inner wall of the through groove 112; the stepped ring platform 113 between the passage T1 and the avoidance openings 114 on both sides forms the stopping portion; the avoidance openings 114 provide avoidance space for the deformation of the stopping portion.

[0080] Since the avoidance opening 114 provides an avoidance space for the deformation of the stopper, the resistance encountered by the sub-buckle 12 during the insertion process is reduced. The design of the avoidance opening 114 also enables the sub-buckle 12 to pass through the passage T1 more smoothly during the insertion process, further improving the convenience of the clamping.

[0081] Furthermore, the stoppers on both sides are arranged to extend and intersect, and the stoppers on both sides are arranged in an "eight" shape, and the width of the passage T1 gradually decreases from the first hole 11a to the second hole 11b. The stoppers on both sides are arranged to extend and intersect, and this structure can provide a gradual guiding effect when the sub-buckle 12 passes through the passage T1. This allows the sub-buckle 12 to enter the mother buckle 11 more smoothly, reducing the resistance or jamming caused by size mismatch. This not only improves the efficiency of the clamping, but also reduces the difficulty of operation for users.

[0082] In this embodiment, in the penetration direction of the through groove 112, the stepped ring platform 113 divides the through groove 112 into a first concave cavity 112a and a second concave cavity 112b; the sub-buckle 12 includes a first shaft buckle 122 and a second shaft buckle 123 arranged along its axial direction, and a radial depression between the two forms the buckling portion 121; the first concave cavity 112a and the second concave cavity 112b respectively correspond to the first shaft buckle 122 and the second shaft buckle 123, so that the second orifice 11b is engaged and connected with the buckling portion 121.

[0083] The first cavity 112a and the second cavity 112b are respectively matched with the first shaft buckle 122 and the second shaft buckle 123. This design increases the contact area between the sub-buckle 12 and the mother buckle 11. By increasing the contact area, the friction and stability between the connection points are enhanced, thereby improving the reliability of the connection. In addition, the first cavity 112a and the second cavity 112b cooperate with the first shaft buckle 122 and the second shaft buckle 123, especially the snap-fit ​​connection with the buckle 121, to form a stable locking structure. This structure can prevent the sub-buckle 12 from accidentally disengaging when subjected to external force, thereby ensuring the durability and safety of the connection.

[0084] Furthermore, the axial extension length of the buckle portion 121 is mutually adapted to the hole depth of the second orifice 11b; the outer contour of the buckle portion 121 is an arcuate transition, and the inner walls of the first orifice 11a and the second orifice 11b are mutually adapted to the buckle portion 121. The outer contour of the buckle portion 121 adopts an arcuate transition design, which makes the contact between the outer surface of the sub-button 12 and the inner wall of the mother buckle 11 smoother during the insertion process. The arcuate transition effectively reduces friction and resistance, allowing the sub-button 12 to enter more easily and stay in the correct position.

[0085] Furthermore, the female buckle 11 is arranged on the side wall of the support frame G2, and the female buckle 11 is fixedly connected to the support frame G2 through a plurality of fasteners 14; the end of the sub-buckle 12 away from the buckle 121 is provided with a fitting portion 124, and the fitting portion 124 is a polygonal column type. The sub-buckle 12 is engaged with the end of the beam H1 through the fitting portion 124 and is fixedly connected through a plurality of fasteners 14. The fitting portion 124 on the sub-buckle 12 is designed to be a polygonal column type, and this design makes it easier to align and embed the sub-buckle 12 when connected to the beam H1. The polygonal column type structure provides more contact points and positioning surfaces, thereby increasing the stability and accuracy of the connection.

[0086] Through the above scheme of the utility model, in specific applications: first, the support frame G2 is preliminarily formed by connecting multiple side beams S1 end to end in a triangular structure; the inner side walls of the support frames G2 on both sides are provided with female buckles 11, and the two ends of the cross beam H1 are respectively provided with sub buckles 12; at the same time, multiple connecting fasteners 2 are sleeved on the cross beam H1;

[0087] The mother buckle 11 is provided with a first hole 11a and a second hole 11b which are connected to each other. The sub-buckle 12 is inserted from the first hole 11a into the second hole 11b to realize the rapid assembly of the cross beam H1 and the support frame G2, so as to meet the high-efficiency assembly operation of the flood control sub-dike. A flexible stopper 13 is provided at the connection between the first hole 11a and the second hole 11b. The sub-buckle 12 is constrained in the second hole 11b by the stopper 13 to avoid accidental disengagement, thereby ensuring the reliable cooperation between the sub-buckle 12 and the mother buckle 11 and improving the firmness of the flood control sub-dike.

[0088] Next, the stud 24 on the locking portion 23 of the connecting fastener 2 is exposed from the through hole 32 on the baffle, and the locking hand wheel 25 cooperates with the stud 24 to be tightened, so that the baffle 3 can be connected to the beam H1, which is convenient and flexible to splice; at the same time, a sealing gasket 26 is arranged on the inner side of the locking nut, and the sealing gasket 26 is used to seal the surrounding side of the water-facing surface of the through hole 32 to prevent floods from penetrating in, thereby having a good anti-flood and waterlogging effect.

[0091] In this embodiment, the connecting fastener 2 is in a U-shaped structure, including a mounting seat 51, and the mounting seat 51 is fixedly connected to the baffle 3 through a fastener 14; a clamping portion 52 is provided on each side of the mounting seat 51, and the connecting fastener 2 clamps the baffle 3 on the beam H1 through the clamping portion 52. The clamping portion 52 is quickly clamped on the corresponding beam H1, which is convenient to operate, low in cost, and easy to produce.

[0093] like Fig.16 , Fig.17 As shown, this embodiment provides a portable and detachable flood control sub-embankment assembly. The features not explained in this embodiment are explained in Example 1 and will not be repeated here. The difference between this embodiment and Example 1 is:

[0094] The support frame G2 is formed by multiple side beams S1 connected end to end in sequence, and the cross beam H1 and the side beams S1 on the two support frames G2 are laterally connected to form a fixed frame G1 through quick-release fasteners 1; the quick-release fasteners 1 are respectively provided on the opposite sides of each side beam S1, and the quick-release fasteners 1 on both sides are mirror-imaged; specifically, a female buckle 11 is respectively provided on both sides of the side beam S1, wherein the female buckle 11 on one side is provided with a bolt, and the female buckle 11 at the opposite position on the other side is provided with a nut, the bolt passes through the female buckle 11 and the side beam S1 in sequence, and is connected with the nut on the other side, so as to fix the female buckles 11 on both sides to the side beam S1; the fixed frame G1 is connected laterally in a row in sequence through the quick-release fasteners 1 on the two outer end faces, that is, the sub-buckles 12 on the cross beam H1 are correspondingly engaged with the female buckles 11 on the side beam S1, and are sequentially connected laterally in a row. Through the quick-release fastener 1, the fixing frame G1 can be laterally combined with the subsequent fixing frame G1 to form a row. This connection method not only increases the stability of the flood control sub-dike assembly, but also can meet various complex installation environments and layout requirements according to the actual needs of the flood control and waterlogging relief site, greatly increasing its applicability.
