Description

Technical Field

[0001] The utility model relates to the technical field of flood control devices, in particular to a quick-install flood control sub-dike panel structure. Background Art

[0002] The assembled flood-control sub-dike is a temporary dam structure built to prevent floods from overflowing. It is usually used as a reserve of emergency equipment in designated warehouses for the country, river basins, provinces and cities. 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. Before the flood comes, people will assemble the flood-control sub-dikes to withstand the impact of the flood and protect the surrounding farmland and cities. Among them, the panel structure of the flood-control sub-dike directly blocks the impact of the flood, and needs to have sufficient strength and durability to withstand the pressure and impact of the flood. Therefore, the reliability of the flood-control sub-dike panel structure is particularly important for the implementation of flood control and disaster prevention operations.

[0003] In the prior art, a Chinese patent with publication number CN202214707U provides a plug-in sub-dike, including a frame and a water retaining plate fixed on the frame. A U-shaped spring clip is fixed to the back of the water retaining plate of the plug-in sub-dike by a fastener, and the spring clip is connected to the crossbeam to achieve the connection between the water retaining plate and the frame. The spring clip provides convenience for the assembly of the water retaining plate to a certain extent, but the existing panel structure using the U-shaped spring clip has the following defects: (1) The connection reliability between the U-shaped spring clip and the crossbeam is poor, and the water retaining plate is easily disengaged due to excessive water flow impact; (2) The spring clip is pre-fixed on the water retaining plate. During transportation, the water retaining plates are usually stacked, and the overlapping of each other easily causes the spring clip to deform; (3) Because the water retaining plates are pre-fixed with spring clips, the height is increased when they are stacked, which occupies transportation space.

[0004] Therefore, in view of the problems existing in the prior art, there is an urgent need to provide a quick-install flood control sub-dike panel structure. Summary of the invention

[0005] In order to overcome the problems existing in the above-mentioned prior art, the utility model proposes a quick-install flood control sub-dike panel structure, which is connected to the water retaining panel by a floating ring fixer sleeved on the crossbeam, thereby ensuring the reliability of the installation of the water retaining panel and the efficiency of disassembly and assembly.

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

[0007] A quick-install flood-proof sub-dike panel structure comprises a water retaining panel and a plurality of cross beams; a plurality of floating ring fixers are sleeved on the cross beams, and the water retaining panel is connected to the cross beams through the floating ring fixers;

[0008] The floating ring fixer comprises a ring buckle, and a through ring opening is provided on the ring buckle. The ring buckle is sleeved on the cross beam through the ring opening and slides along the extension direction of the cross beam;

[0009] At least one side of the ring buckle protrudes in a direction away from the ring opening to form a connecting portion; a positioning stud is fixedly connected to the connecting portion, and a through hole is correspondingly provided on the water retaining panel, and the positioning stud is exposed through the through hole;

[0010] It also includes a locking hand wheel, the inner side of which is provided with a sealing gasket; when the locking hand wheel cooperates with the positioning stud to be tightened, the inner side of the locking hand wheel presses against the water retaining panel, and the sealing gasket is sealed on the peripheral side of the perforated water-facing surface.

[0011] In the utility model, the water retaining panel can be connected to the crossbeam through the locking cooperation of the locking hand wheel and the positioning stud, which is convenient and flexible to splice, and meets the high-efficiency operation in the actual anti-flood and flood prevention process; and because the swimming ring fixer and the water retaining panel are separated, there is no need to pre-fix them on the water retaining panel, and the space occupied is small when stacked, and the connecting accessories such as the swimming ring fixer 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 anti-flood and flood prevention effect.

[0012] As a further improvement of the above solution, a flat first abutting surface is provided on the side of the connecting portion facing the water retaining panel; the positioning stud is perpendicular to the first abutting surface; when the locking hand wheel and the positioning stud are tightened, the water retaining panel is pressed against the first abutting surface.

[0013] The flat first abutting surface can ensure that the contact surface between the water retaining panel and the connecting part is uniform and tight, and minimize the gap between the contact surfaces, thereby providing stronger stability and sealing. Secondly, the design of the positioning stud perpendicular to the first abutting surface ensures the effective transmission of the locking force. When the locking hand wheel cooperates with the positioning stud to tighten, the locking force can be evenly applied along the axial direction of the stud, avoiding the deflection or dispersion of the locking force. This design not only improves the reliability of locking, but also ensures that the water retaining panel can be evenly pressed against the first abutting surface, further enhancing the stability of the connection. Finally, when the locking hand wheel cooperates with the positioning stud to tighten, the water retaining panel is tightly pressed against the first abutting surface. This close contact not only increases the firmness of the connection, but also effectively prevents the loosening or displacement of the water retaining panel. During long-term use, this stable locking mechanism can maintain the reliability of the connection, reduce maintenance costs, and extend the service life of the product.

[0014] As a further improvement of the above solution, a flat second abutting surface is provided on the side wall of the ring opening of the ring buckle facing the water retaining panel; the first abutting surface is connected to or separated from the second abutting surface, both are on the same plane, and jointly abut against the back water surface of the water retaining panel.

[0015] The flat second abutment surface ensures gapless contact with the water retaining panel, 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 abutment surface is connected or separated from the second abutment surface, but the two are on the same plane. This design further increases the contact area with the water retaining panel, forming a continuous, large-area abutment surface. The large-area abutment surface can provide better support and stability, making it difficult for the water retaining panel to deform or displace when subjected to external forces.

[0016] As a further improvement of the above scheme, there are multiple crossbeams, and the multiple crossbeams are arranged in parallel with each other; the first abutment surface and the second abutment surface of each swimming ring fixture on the crossbeam are all on the same plane. The first abutment surface and the second abutment surface of each swimming ring fixture on the crossbeam are all on the same plane, which is crucial to ensure the stability of the connection. When these abutment surfaces are all on the same plane, they can contact and cooperate with other components, such as water retaining panels, at the same time and evenly. This uniform contact distribution helps to reduce stress concentration and prevent connection failure caused by local water flow impact.

[0017] As a further improvement of the above scheme, the ring buckle is a rectangular ring shape, which is adapted to the cross-sectional shape of the beam; the ring buckle is a fully closed loop structure; or a partially open loop structure. Since the shape of the ring buckle matches that of the beam, the ring buckle can be easily put on the beam during installation without complicated alignment or adjustment process. This design reduces the installation steps and time, and improves work efficiency. Secondly, the fully closed loop structure design of the ring buckle also provides convenience for connection. The fully closed loop structure means that the ring buckle has no openings, so there is no need to worry about the ring buckle accidentally falling off or misaligned during installation. This design simplifies the installation process, makes the operation smoother, and reduces uncertainty during the installation process.

[0018] In addition, when the ring buckle adopts a partially open-loop structure, although there is an opening, this design is also convenient. The partially open-loop structure allows the ring buckle to be flexibly adjusted within a certain range, which is convenient for adapting to beams of different sizes or dealing with minor deviations during installation. This flexibility reduces the difficulty of installation and makes the connection process smoother.

[0019] As a further improvement of the above scheme, the buckle and the connecting part are made of plastic material; during injection molding, the buckle, the connecting part and the positioning stud are integrally molded. The one-piece structural design eliminates the presence of seams or connection points between the various components, thereby eliminating potential stress concentration areas and improving the strength of the overall structure. During the injection molding process, the plastic melts at high temperature and fills the mold, and forms a solid whole after cooling, ensuring the tight connection and coordinated work between the buckle, the connecting part and the positioning stud.

[0020] As a further improvement of the above scheme, one end of the positioning stud extends into the connecting part along its axial direction, and the extended end is columnar or block-shaped protruding along the circumferential direction; the other end of the positioning stud is provided with a threaded portion, and is threadedly connected to the locking handwheel through the threaded portion. Whether it is a columnar extending end or a block-shaped protruding along the circumferential direction, the contact area between the connecting part and the positioning stud can be effectively increased, thereby dispersing and bearing more external forces, and significantly improving the strength of the overall structure.

[0021] As a further improvement of the above scheme, the locking hand wheel includes a base shaft portion, a threaded hole is provided at the center axis of one end of the base shaft portion, and the threaded hole is adapted to the threaded portion of the positioning stud; a sealing gasket is also provided on the end face of the base shaft portion, and the sealing gasket is arranged around the circumference of the threaded hole; and a hand-tightening portion for force application and rotation is provided at the other end of the base shaft portion. A sealing gasket is provided on the end face of the base shaft portion, and the elasticity and sealing property of the sealing gasket are utilized. When the locking hand wheel is threadedly connected to the positioning stud and tightened, the sealing gasket can effectively fill the small gap between the base shaft portion and the water retaining panel to prevent the intrusion of water flow, thereby significantly improving the sealing performance of the locking structure.

[0022] As a further improvement of the above scheme, the water retaining panel includes a plurality of baffle units, one side of the baffle unit is provided with a slot, and the other side is provided with a plug-in plate; when the plurality of baffle units are connected in sequence, the slot of the preceding baffle unit is connected with the plug-in plate of the following baffle unit, and they are continuously combined into a row. By designing the water retaining panel as a combination of a plurality of baffle units, each baffle unit has an independent slot and plug-in plate, making the disassembly and assembly of the entire water retaining panel very flexible. Users can easily add or reduce the number of baffle units according to the needs of the flood control site, thereby improving the applicability of the product and reducing maintenance costs.

[0023] As a further improvement of the above scheme, each baffle unit is arranged in an undulating shape along the width dimension direction of its board surface, including concave panels and convex panels that are alternately connected in sequence; there is a distance between the bottom of the concave panel and the top of the convex panel; when assembled, the inner side of the locking handwheel is pressed against the bottom of the water-facing surface of the concave panel. The alternating arrangement of the concave panel and the convex panel not only enhances the structural strength of the baffle unit, but also makes the position of the locking handwheel reasonably arranged. By placing the locking handwheel at the bottom of the concave panel, the protruding part of the locking handwheel can be effectively reduced, reducing the space occupied during construction, and avoiding the risk of locking failure caused by human accidental contact.

[0024] Beneficial effects of the utility model:

[0025] (1) Stable and reliable, the water retaining panel can be connected to the beam by locking the locking hand wheel and the positioning stud, which is convenient and flexible to splice, meeting the high-efficiency operation in the actual flood control process;

[0026] (2) Since the swimming ring holder is separated from the water retaining panel, it does not need to be fixed on the water retaining panel in advance. When stacked, it takes up little space and does not cause deformation of the swimming ring holder and other connecting accessories. It is easy to pack and transport, and has strong economic benefits.

[0027] (3) A sealing gasket is arranged on the inner side of the locking nut, and the sealing gasket is used to seal the peripheral side of the water-facing surface of the perforation to prevent floods from penetrating into the perforation, thereby achieving good flood prevention and waterlogging prevention effects.

[0043] 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.

[0044] like Figure 1-Figure 5 As shown, a quick-install flood-proof sub-dike panel structure includes a water retaining panel 3 and a plurality of cross beams H1; a plurality of floating ring fixers 2 are sleeved on the cross beam H1, and the water retaining panel 3 is connected to the cross beam H1 through the floating ring fixers 2; specifically, the cross beam H1 has two, which can be made of aluminum alloy square tubes, and the two cross beams H1 are arranged in parallel with each other; each cross beam H1 is sleeved with three floating ring fixers 2 distributed at intervals;

[0045] The floating ring fixer 2 includes a ring buckle 21, and a through ring opening 22 is provided on the ring buckle 21. The ring buckle 21 is sleeved on the cross beam H1 through the ring opening 22 and slides along the extension direction of the cross beam H1.

[0046] At least one side of the ring buckle 21 protrudes in a direction away from the ring mouth 22 to form a connecting portion 23; the connecting portion 23 is fixedly connected to a positioning stud 24, and a corresponding through-hole 32 is provided on the water retaining panel 3, and the positioning stud 24 is exposed through the through-hole 32; it also includes a locking hand wheel 25, and a sealing gasket 26 is provided on the inner side of the locking hand wheel 25; when the locking hand wheel 25 and the positioning stud 24 are tightened in cooperation, the inner side of the locking hand wheel 25 presses against the water retaining panel 3, and the sealing gasket 26 is blocked on the peripheral side of the water-facing surface of the through-hole 32.

[0047] In this embodiment, the ring buckle 21 is a rectangular ring shape, which is adapted to the cross-sectional shape of the beam H1; the ring buckle 21 is a fully closed loop structure; or a partially open loop structure. Since the ring buckle 21 matches the shape of the beam H1, the ring buckle 21 can be easily put on the beam H1 during installation without complicated alignment or adjustment process. This design reduces the installation steps and time, and improves work efficiency. Secondly, the fully closed loop structure design of the ring buckle 21 also provides convenience for connection. The fully closed loop structure means that the ring buckle 21 has no openings, so there is no need to worry about the ring buckle 21 accidentally falling off or misaligned during the installation process. This design simplifies the installation process, makes the operation smoother, and reduces uncertainty during the installation process.

[0048] In addition, when the ring buckle 21 adopts a partially open-loop structure, although there is an opening, this design is also convenient. The partially open-loop structure allows the ring buckle 21 to be flexibly adjusted within a certain range, so as to adapt to beams H1 of different sizes or to cope with slight deviations during installation. This flexibility reduces the difficulty of installation and makes the connection process smoother.

[0049] In this embodiment, the buckle 21 and the connecting portion 23 are made of plastic material, specifically PA plastic; during injection molding, the buckle 21, the connecting portion 23 and the positioning stud 24 are integrally injection molded. The integrally molded structural design eliminates seams or connection points between the components, thereby eliminating potential stress concentration areas and improving the strength of the overall structure. During the injection molding process, the plastic melts at high temperature and fills the mold, and forms a solid whole after cooling, ensuring the tight connection and coordinated work between the buckle 21, the connecting portion 23 and the positioning stud 24.

[0050] In this embodiment, one end of the positioning stud 24 extends into the connecting portion 23 along its axial direction, and the extended end is columnar or block-shaped protruding along the circumferential direction; the other end of the positioning stud 24 is provided with a threaded portion 241, and is threadedly connected to the locking handwheel 25 through the threaded portion 241. Whether it is a columnar extending end or a block-shaped protruding along the circumferential direction, the contact area between the connecting portion 23 and the positioning stud 24 can be effectively increased, thereby dispersing and bearing more external forces, and significantly improving the strength of the overall structure.

[0051] In this embodiment, the locking hand wheel 25 comprises a base shaft portion 251, a threaded hole 252 is provided at the center axis of one end of the base shaft portion 251, and the threaded hole 252 is adapted to the threaded portion 241 of the positioning stud 24; a sealing gasket 26 is also provided on the end surface of the base shaft portion 251, and the sealing gasket 26 is arranged around the circumference of the threaded hole 252; and a hand-tightening portion 253 for applying force and rotating is provided at the other end of the base shaft portion 251. Specifically, the hand-tightening portion 253 can be configured into various shapes according to requirements.

[0052] A sealing gasket 26 is provided on the end face of the base shaft portion 251. The elasticity and sealing properties of the sealing gasket 26 are utilized. When the locking handwheel 25 is threadedly connected to the positioning stud 24 and tightened, the sealing gasket 26 can effectively fill the tiny gap between the base shaft portion 251 and the water retaining panel 3 to prevent the intrusion of water flow, thereby significantly improving the sealing performance of the locking structure.

[0053] In this embodiment, the connecting portion 23 is provided with a flat first abutting surface 231 on one side facing the water retaining panel 3; the positioning stud 24 is perpendicular to the first abutting surface 231; when the locking hand wheel 25 cooperates with the positioning stud 24 to be tightened, the water retaining panel 3 is pressed against the first abutting surface 231.

[0054] The flat first abutting surface 231 can ensure that the contact surface between the water retaining panel 3 and the connecting portion 23 is uniform and tight, and the gap between the contact surfaces is minimized to provide stronger stability and sealing. Secondly, the design of the positioning stud 24 perpendicular to the first abutting surface 231 ensures the effective transmission of the locking force. When the locking hand wheel 25 is tightened with the positioning stud 24, the locking force can be evenly applied along the axial direction of the stud, avoiding the deflection or dispersion of the locking force. This design not only improves the reliability of locking, but also ensures that the water retaining panel 3 can be evenly pressed on the first abutting surface 231, further enhancing the stability of the connection. Finally, when the locking hand wheel 25 is tightened with the positioning stud 24, the water retaining panel 3 is tightly pressed on the first abutting surface 231. This close contact not only increases the firmness of the connection, but also effectively prevents the loosening or displacement of the water retaining panel 3. During long-term use, this stable locking mechanism can maintain the reliability of the connection, reduce maintenance costs, and extend the service life of the product.

[0055] In this embodiment, the ring buckle 21 is provided with a flat second abutting surface 232 on the side wall of the ring opening 22 facing the water retaining panel 3; the first abutting surface 231 is connected or separated from the second abutting surface 232, and the two are on the same plane, and they abut against the back surface of the water retaining panel 3 together. The flat second abutting surface 232 ensures the gapless contact with the water retaining panel 3, so that the pressure can be distributed more evenly when locking, thereby improving the stability of the locking. The loosening or leakage problem caused by local stress concentration is effectively prevented; in addition, the first abutting surface 231 is connected or separated from the second abutting surface 232, but the two are on the same plane. This design further increases the contact area with the water retaining panel 3, forming a continuous, large-area abutting surface. The large-area abutting surface can provide better support and stability, so that the water retaining panel 3 is not easy to deform or displace when subjected to external forces.

[0056] The first abutting surface 231 and the second abutting surface 232 of each swimming ring fixture 2 on the crossbeam H1 are all on the same plane. The first abutting surface 231 and the second abutting surface 232 of each swimming ring fixture 2 on the crossbeam H1 are all on the same plane, which is crucial to ensure the stability of the connection. When these abutting surfaces are all on the same plane, they can contact and cooperate with other components, such as the water retaining panel 3, at the same time and evenly. This uniform contact distribution helps to reduce stress concentration and prevent connection failure caused by local water flow impact.

[0057] In this embodiment, the water retaining panel 3 includes a plurality of baffle units 31, one side of the baffle unit 31 is provided with a slot 31a, and the other side is provided with a plug plate 31b; when the plurality of baffle units 31 are connected in sequence, the slot 31a of the previous baffle unit 31 is connected with the plug plate 31b of the next baffle unit 31, and they are continuously combined into a row. By designing the water retaining panel 3 as a combination of a plurality of baffle units 31, each baffle unit 31 has an independent slot 31a and plug plate 31b, so that the disassembly and assembly of the entire water retaining panel 3 becomes very flexible. Users can easily add or reduce the number of baffle units 31 according to the needs of the flood control site, thereby improving the applicability of the product and reducing the maintenance cost.

[0058] In this embodiment, each baffle unit 31 is arranged in an undulating shape along the width dimension direction of its board surface, including a concave panel 311 and a convex panel 312 that are alternately connected in sequence; there is a distance between the bottom of the concave panel 311 and the top of the convex panel 312; when assembled, the inner side of the locking hand wheel 25 is pressed against the bottom of the water-facing surface of the concave panel 311. The alternating arrangement of the concave panel 311 and the convex panel 312 not only enhances the structural strength of the baffle unit 31, but also makes the position of the locking hand wheel 25 reasonably arranged. By placing the locking hand wheel 25 at the bottom of the concave panel 311, the protruding part of the locking hand wheel 25 can be effectively reduced, reducing the space occupied during construction, and avoiding the risk of locking failure caused by human accidental contact.

[0059] Through the above scheme of the utility model, in specific applications: first, the swimming ring fixer 2 is sleeved on the beam H1, so that the positioning stud 24 is exposed from the perforation 32 on the water retaining panel 3; then, the water retaining panel 3 can be connected to the beam H1 by locking the locking hand wheel 25 and the positioning stud 24, which is convenient and flexible to splice, and meets the high-efficiency operation in the actual flood control process; because the swimming ring fixer 2 and the water retaining panel 3 are separated, it does not need to be fixed on the water retaining panel 3 in advance, and the space occupied is small when stacked, and the connecting accessories such as the swimming ring fixer 2 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 block the surrounding side of the water-facing surface of the perforation 32 to prevent floods from penetrating, and has a good flood control and flood prevention effect.

[0060] According to the disclosure and teaching of the above specification, the technicians in the field of the utility model can also change and modify the above implementation. Therefore, the utility model is not limited to the specific implementation methods disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of explanation and do not constitute any limitation to the utility model.
