[0051] The present application will be further described below in conjunction with the drawings and specific embodiments. It should be noted that the embodiments described below or technical features thereof can be combined with each other or other embodiments or technical features to form new embodiments without conflict. It should be understood that the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0052] Please refer to Figures 1 to 12 , the present application provides a technical solution:

[0053] Embodiment one, single module assembly stage of flood control sub-dyke.

[0054] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the single flood control sub-dyke module takes two triangular hinged frames 1 as the core support structure, with a welding assembly beam 2 inside, and a water blocking sub-plate 3 fixed outside the assembly beam 2 by bolts, and the water blocking sub-plate 3 is made of high-strength alloy material with excellent waterproof performance, and a folding mechanism 4 is arranged at the bottom center of the triangular hinged frame 1. When assembling, the operator first unfolds the triangular hinged frame 1 from the storage state: in the folding mechanism 4, a No. 1 hinged joint 41 fixed at one end of the bottom of the triangular hinged frame 1 is rotatably connected to a No. 2 hinged joint 42 inside through a middle shaft 43, and the other ends of the middle shaft 43 are connected to the No. 1 hinged joint 41 through bearings, and the other end of the No. 2 hinged joint 42 is fixed to the other end of the bottom of the triangular hinged frame 1. The operator pushes the two side frames of the triangular hinged frame 1 to make the No. 2 hinged joint 42 rotate inside the No. 1 hinged joint 41 around the middle shaft 43, until the water blocking sub-plate 3 forms an inclined water blocking surface with the ground at an angle of 60°, and the parts of the No. 1 hinged joint 41 and the No. 2 hinged joint 42 connected to the triangular hinged frame 1 are in a horizontal state.

[0055] Wherein when the triangular hinged frame 1 is in the storage state, the folding mechanism 4 presents a triangle without a bottom side, and the same shape as the storage shape of the triangular hinged frame 1, and the bottom side is all stored in the triangular hinged frame 1.

[0056] In addition, the embedded groove 403 opened at the bottom of the No. 1 hinged joint 41 is to allow the shaft sleeve rod 44 and the wedge-shaped plate 47 to reverse deflection during the storage process of the folding mechanism 4, until the wedge-shaped plate 47 is embedded with the embedded groove 403, to avoid the gap between the wedge-shaped plate 47 and the No. 1 hinged joint 41 and the No. 2 hinged joint 42 during storage, and to affect the subsequent unfolding action.

[0057] Then manually rotate the shaft sleeve rod 44 fixed at both ends of the middle shaft 43, and the outer connecting shaft 45 connected to the bottom of the shaft sleeve rod 44 through the bearing rotates synchronously, and the flexible sleeve 46 (made of wear-resistant rubber material) outside the outer connecting shaft 45 gradually clamps into the notch 48 (the inner diameter of the bottom is larger than the top to ensure that it is not easy to come out after clamping) opened outside the No. 1 hinged joint 41; at the same time, the wedge-shaped plate 47 fixed at the end of the outer connecting shaft 45 away from the shaft sleeve rod 44 rotates with the outer connecting shaft 45, enters the gap between the No. 1 hinged joint 41 and the No. 2 hinged joint 42, and is squeezed and fitted on both sides with the inner wall of the No. 1 hinged joint 41 and the outer wall of the No. 2 hinged joint 42, and finally the wedge-shaped plate 47 is embedded in the gap between the No. 1 hinged joint 41 and the No. 2 hinged joint 42, to complete the preliminary limiting of the folding mechanism 4, to prevent the triangular hinged frame 1 from rebounding due to its own weight.

[0058] Through the articulated structure of "No. 1 articulated joint 41-No. 2 articulated joint 42-intermediate shaft 43", the rapid deployment of the triangular articulated frame 1 is realized, and the single module assembly time is shortened to within 5 minutes; the double limiting design of the flexibility sleeve 46 and the gap between the notched groove 48 and the wedge-shaped plate 47 and the No. 1 articulated joint 41 and the No. 2 articulated joint 42 ensures the stability of the triangular articulated frame 1 structure after assembly, and meets the needs of medium and low intensity flood conditions.

[0059] Example two, multi-module splicing and reinforcement stage.

[0060] As shown in Figure 6 and Figure 7 , when the single module assembly is completed, the multiple flood prevention sub-dyke modules are quickly spliced by assembling the pre-set sleeve at both ends of the cross beam 2, and the sleeve adopts a buckle type structure: the operator inserts the male buckle of the cross beam 2 of the previous module into the female slot of the next module, and rotates 90° clockwise to complete the locking, without the need for additional tools, realizing "seamless splicing".

[0061] Among them, the receiving hole 6 opened on the inner wall of both sides of the triangular articulated frame 1 is used for storing and protecting the positioning mechanism 5 in the storage state.

[0062] Splicing synchronous starting reinforcement mechanism: the reinforcement unit 49 at both ends of the No. 2 articulated joint 42 responds synchronously with the deflection of the wedge-shaped plate 47. That is, when the wedge-shaped plate 47 is deflected upward, it extrudes the sliding plate 492 inside the outer connecting rail 491 fixed on the outer end surface of the No. 2 articulated joint 42. The sliding plate 492 moves upward under the elastic force of the bottom No. 2 spring 493, wherein the two ends of the No. 2 spring 493 are fixedly connected with the sliding plate 492 and the No. 2 articulated joint 42, and the No. 2 spring 493 also plays a role in resetting the sliding plate 492. Then the sliding plate 492 drives the top welded opening seat 494 to move upward synchronously, until the top of the opening seat 494 at both ends is extruded and fitted with the limiting piece 495 fixed at the top of the inner cavity of the outer connecting rail 491. At this time, the axis of the opening seats 494 of the adjacent two modules is aligned, and the operator passes the steel reinforcing rod through the aligned opening seats 494 in sequence, and locks it through the nut, further enhancing the connection strength between the modules, avoiding the dislocation of the modules caused by water impact. This operation is a post-hand measure.

[0063] The buckle type sleeve realizes the rapid splicing of multiple modules, and the splicing efficiency is improved; the cooperation of the reinforcement unit 49 and the reinforcing rod improves the connection strength between the modules and enhances the water impact resistance; the tension adjustment design of the No. 2 pull strip 59 and the tensioning rod 50 ensures that the overall stress of the sub-dyke is balanced, avoids structural damage caused by local stress concentration, and adapts to long-term flood prevention needs.

[0064] Example three, complex terrain adaptive positioning stage.

[0065] As shown in Figure 8 , Figure 9 ,Figure 10 、 Figure 11 and Figure 12 As shown in the figure, if the terrain along the river is complex, such as there are protrusions, depressions or soft ground, the two positioning mechanisms 5 on the inner bottom of the triangular hinged frame 1 work synchronously to ensure that the sub-dyke is closely attached to the ground: the sleeve 51 of the positioning mechanism 5 is welded on the inner bottom of the triangular hinged frame 1, the inner wall of the sleeve 51 is provided with a variable-diameter groove 52, and the variable-diameter groove 52 corresponds to different height levels at different diameter sections, and an inner sliding column 53 is slidably fitted inside; the operator depresses the inner sliding column 53 according to the height difference of the ground, the ball buckle 54 in the circumferential arc-shaped groove on the outer wall of the inner sliding column 53 slides along the variable-diameter groove 52, and when the ball buckle 54 is clamped into the corresponding diameter section of the variable-diameter groove 52, the height of the inner sliding column 53 is locked, the height of the sub-dyke is adjusted, and the adjustment range is about 50mm, ensuring that the bottom of the water-blocking sub-plate 3 is seamlessly attached to the ground, preventing water from seeping from the bottom. The combination of the sleeve 51, the variable-diameter groove 52, the inner sliding column 53 and the ball buckle 54 adopts the principle of spring buckle.

[0066] The No. 3 spring 55 fixed at the bottom of the inner sliding column 53 provides buffering and resetting, wherein one end of the No. 3 spring 55 is welded with the inner sliding column 53, and the other end is welded with the inner set ring 56 fixed in the inner cavity of the bottom of the triangular hinged frame 1, avoiding the problem of wear or breakage caused by the stress between the sleeve 51 and the inner sliding column 53 due to the protrusions on the ground; if the ground is soft, such as muddy ground, the telescopic support 57 fixed in the inner cavity at the bottom of the inner sliding column 53 can be extended outward and inserted into the interior of the muddy ground, increasing the contact area with the ground and reducing the ground pressure, preventing the sub-dyke from sinking and tilting. In addition, for the ground with high and low undulations and hard and solid soil, the height of the four telescopic supports 57 can be adjusted to keep the entire flood control sub-dyke in a horizontal state, thereby facilitating the assembly and processing of the flood control sub-dyke by the operator, without the need for manual excavation and leveling, such as shoveling protrusions, filling soil to fill pits to compensate for large terrain height differences, and additional labor.

[0067] At the same time, the bottom end of the inner sliding column 53 is initially extruded with the No. 1 L-shaped rod 40, wherein the No. 1 L-shaped rod 40 is slidably fitted in the No. 1 hinged head 41 mounting groove, the outer side is fixed with the No. 1 tension bar 401, the other end of the No. 1 tension bar 401 is fixed with the external shaft 45, and the movement of the inner sliding column 53 is limited; when the folding and unfolding mechanism 4 is assembled and the flexible sleeve 46 is clamped into the slot 48, the external shaft 45 drives the No. 1 tension bar 401 to pull the No. 1 L-shaped rod 40 to move towards the No. 1 hinged head 41, compressing the No. 1 spring 402 in the mounting groove, and releasing the extrusion limiting of the inner sliding column 53, ensuring the normal work of the positioning mechanism 5. Thus, it avoids the telescopic support 57 from extending outward due to accidental touch of the positioning mechanism 5 in the storage state, avoiding bending and wear.

[0068] Wherein the role of the second L-shaped rod 58 and the second stay 59 is the same as the first L-shaped rod 40 and the first stay 401, but the second L-shaped rod 58 and the second stay 59 correspond to another set of positioning mechanism 5, and the other tension rod 50 is used to cooperate with the outer shaft 45 and drive the second stay 59 and the second L-shaped rod 58 to move towards the center, so that the second stay 59 is pulled by the outer shaft 45.

[0069] When the wedge-shaped plate 47 is in the embedded groove 403, the first stay 401 and the second stay 59 are not under external force, but when the wedge-shaped plate 47 is pulled out of the embedded groove 403 with the outer shaft 45, the first stay 401 and the second stay 59 begin to be stressed, and only when the flexible sleeve 46 is completely inserted into the top end of the slot 48, the first L-shaped rod 40 and the second L-shaped rod 58 no longer limit the telescopic support 57, that is, during the movement of the outer shaft 45 from the embedded groove 403 to the slot 48, the first stay 401 and the second stay 59 are stressed, but when it moves to the top of the slot, the first stay 401 and the second stay 59 are no longer stressed, and the first L-shaped rod 40 and the second L-shaped rod 58 are away from the telescopic support 57.

[0070] The height fine-tuning function of the positioning mechanism 5 adapts to complex terrain and improves the fit between the sub-dyke and the ground; the telescopic support 57 effectively reduces the ground pressure, avoids the sinking of soft ground, or still maintains the stability of the water-stopping sub-plate 3 when sinking occurs by inserting into the ground, improving the applicability of the sub-dyke in complex terrain; the linkage limiting design of the first L-shaped rod 40 and the first stay 401 ensures that the positioning mechanism 5 is only activated after assembly is completed, avoiding structural loosening during positioning and ensuring operation safety.

[0071] The working principle of the present application: in the assembly stage, first unfold the triangular hinged frame 1, and the bottom center retractable mechanism 4 is the core driving component. The second hinge 42 rotates around the middle shaft 43 in the first hinge 41, driving the two side frames of the triangular hinged frame 1 to open until the water-stopping sub-plate 3 fixed on the outside of the assembly beam 2 forms an inclined water-stopping surface. By manually rotating the shaft sleeve rod 44 at both ends of the middle shaft 43 with the rotating synchronous drive of the outer shaft 45, the flexible sleeve 46 on the outside of the outer shaft 45 gradually clamps into the slot 48 of the first hinge 41, and the inner diameter of the slot bottom is larger than the top, ensuring that the flexible sleeve is not easy to come out after clamping, and at the same time, the wedge-shaped plate 47 at the other end of the outer shaft 45 rotates between the first hinge 41 and the second hinge 42, and the two sides are respectively extruded with the inner wall and the outer wall, and finally embedded in the gap between the first hinge 41 and the second hinge 42, completing the preliminary limiting of the hinged part and preventing the triangular hinged frame from rebounding.

[0072] Synchronous starting reinforcement mechanism: the reinforcement units 49 at both ends of the second hinge joint 42 simultaneously respond to the deflection of the wedge-shaped plate 47, and in the process of upward deflection, the sliding plate 492 in the outer connecting rail 491 is extruded by the wedge-shaped plate 47 and moves upward under the elastic force of the second spring 493, driving the top hole seat 494 to move upward until the top of both ends of the hole seat 494 is extruded and fitted with the limiting piece 495, and finally the operator passes the rod through the two hole seats 494 in turn, and stabilizes the two triangular hinge frames 1, and further locks the position of the second hinge joint 42, avoiding loosening after assembly due to water impact. If the flood control range needs to be expanded, the sleeve assembly at both ends of the cross beam 2 can be assembled to quickly splice multiple flood control sub-dikes to form a continuous water blocking barrier.

[0073] When facing complex terrain, the positioning mechanism 5 ensures that the sub-dike closely fits the ground. The two positioning mechanisms 5 inside the triangular hinge frame 1 work synchronously, and the inner slide column 53 slides up and down in the sleeve 51. The operator presses the inner slide column 53, and the ball buckle 54 in the arc-shaped groove on the outer wall of the inner slide column 53 moves along the variable-diameter groove 52. The different diameter sections of the variable-diameter groove 52 can fix the position of the ball buckle 54, thereby locking the height of the inner slide column 53, and achieving fine adjustment of the overall height of the sub-dike. The third spring 55 at the bottom of the inner slide column 53 provides cushioning and resetting to avoid tilting of the sub-dike due to ground protrusions. The telescopic support 57 at the bottom of the inner slide column 53 can be further extended to enhance the support stability of the sub-dike on soft ground. The purpose of the extrusion state of the inner slide column 53 bottom end and the first L-shaped rod 40 is to prevent the inner slide column 53 from moving up and down. However, when the triangular hinge frame 1 is placed, that is, the folding mechanism is ready, and the flexible sleeve 46 is embedded in the slot 48, the outer connecting shaft 45 in the deflection process will move towards the first hinge joint 41 with the first stay 401 and the first L-shaped rod 40, and compress the first spring 402. At this time, the bottom end of the inner slide column 53 does not limit and extrude the first L-shaped rod 40. In addition, when the outer connecting shaft 45 rotates, it also pulls the second L-shaped rod 58 through the second stay 59, adjusts the tension of the second stay 59 in cooperation with the tension rod 50, ensures that the forces on both sides of the triangular hinge frame 1 are balanced, and improves the overall water flow impact resistance.

[0074] The above embodiments are only preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application. Those skilled in the art can make various modifications without creative labor, which are all within the scope of protection of the present application.
