Abstract
Description
Technical Field
[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a dam device. Background Technology
[0002] Dams are hydraulic structures used to block water flow, prevent flooding, or guide water flow. They play a crucial role in water conservancy projects, protecting people's lives and property and supporting economic and social development. They also provide a stable water source for agricultural irrigation, hydropower generation, and navigation. However, with the combined effects of climate change and human societal development, the hydrological characteristics of rivers are becoming increasingly complex, leading to frequent floods. Damage or breaches in dams can cause severe flooding, resulting in significant losses of life and property. Therefore, the safety and stability of dams are of paramount importance in water conservancy projects.
[0003] The applicant discovered through a search that a Chinese patent discloses "a dam structure" with publication number "CN220619954U". This patent mainly includes multiple dam units and connecting columns. The connecting columns are used to arrange the dam units in a straight line, curve, or polygonal shape to adapt to complex terrain. The dam unit includes several baffles and several connecting bolts. The baffles are provided with a fitting structure. The baffles are connected to each other in a straight line through the fitting structure. The patent also discloses that the front part of the baffle is provided with a front cavity, and the front sides of the front cavity are connected with connecting plates. The front end of the connecting plate is fixed to the front cavity, and the rear end is connected to a rear cavity or a rear plate. The fitting structure includes tongue and groove and tenon and tenon. The connecting plates provided on both sides of the front cavity of the baffle have a supporting function for the front cavity and the rear cavity or rear plate.
[0004] However, in the fitting structure of the baffle and the four types of connecting columns, the tongue and groove is a T-shaped tongue and groove, and the matching tenon is a T-shaped tenon. When the baffles are installed together or the dam unit is installed with the connecting columns, the tongue and groove or tenon of one baffle or connecting column must be inserted from one end to the other end of the tenon or tongue and groove of another baffle or connecting column. This is extremely inconvenient. If the tongue and groove or tenon are slightly deformed or the surface is rough, the insertion resistance is large, and mechanical power must be used for operation. During the operation, cracks or even breakage can easily occur on the front or rear end of the connecting plate of the baffle and the surface of the tongue and groove or tenon of the baffle or connecting column. The technical problem to be solved by this utility model is to provide a dam device that addresses the shortcomings of the above-mentioned prior art. Summary of the Invention

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Each dam panel includes multiple detachable dam units 1. Adjacent dam panels are joined together via the connecting devices 10. Each connecting device 10 includes a straight connecting column 101, a turning connecting column 102, a vertical connecting column 103, a changing-direction connecting column 104, and a four-way connecting column 105. The outer wall of the connecting device 10 is fixedly connected with a mortise and tenon structure. A row of crossbeams 2 is provided on both the inner and outer surfaces of the dam panels, with the ends of the outer row of crossbeams 2 extending to… On one side of the connecting device 10 at both ends of the dam plate, and on the opposite side of the two rows of crossbeams 2, there are M-type fasteners 5. Double-headed bolts 91 pass through between the M-type fasteners 5, and a pad 7 is provided near the M-type fasteners 5. The pad 7 is attached to the outside of the M-type fasteners 5. One side of the dam unit 1 is provided with a tenon 16, and the other side of the dam unit 1 is provided with a tenon 191. The tenon 191 extends into the tenon 16 at one end of the adjacent dam unit 1. The tenon 191, the tenon 16 and the crossbeam 2 are fixedly connected by fastening bolts 9.
[0042] When the dam unit 1 is assembled into a dam slab, the first column of the dam unit faces the water area to resist the impact of strong water flow, reduce water pressure and divert water flow, and enhance the dam device's resistance to water flow impact. Next, the tenon 191 of the dam unit 1 is inserted into the mortise 16 of the adjacent dam unit 1 and fixed by fastening bolts 9. After splicing a certain length, a row of horizontal beams 2 are placed on both the inner and outer sides of the dam slab, and M-type fasteners 5 and pads 7 are snapped onto the outer wall of the beams 2. Finally, it is fixed by double-headed bolts 91 and fastening bolts 9. According to the terrain, two adjacent dam slabs are connected by a connecting device 10. The tenon 191 or mortise 16 of the connecting device 10 is inserted into the mortise 16 or tenon 191 of the adjacent dam slab. The fastening bolts 9 pass through the tenon 191 and mortise 16 and the outer row of beams 2, so that the beams 2 are fixed to the dam slab and the connecting device 10. The dam panel can be installed without the need for external machinery, thus avoiding damage to the dam unit 1 during splicing. At the same time, the crossbeam 2 clamps and fixes the dam panel, improving its stability and resistance to water flow impact.
[0043] like Figure 14 , Figure 15 , Figure 16 , Figure 17 , Figure 18 and Figure 19 As shown, adjacent dam panels are spliced together by connecting devices 10 into straight lines, curves, or polygonal arrangements to adapt to different terrains.
[0044] like Figure 5As shown, the dam unit 1 includes six cavities 1011. The two upper cavities 1011 are trapezoidal, and each of the two cavities 1011 is filled with a first column 12. Multiple double-ended bolts 91 are also provided between the inner and outer crossbeams 2, and the double-ended bolts 91 penetrate the pad 7, the M-shaped fastener 5, the inner and outer crossbeams 2, and the first column 12. The bottom ends of the two upper cavities 1011 are fixedly connected to two rhomboid cavities 1011, and the interior of each of the two rhomboid cavities 1011 is filled with a second column 13. Each of the opposite sides of the cavity 1011 is fixedly connected to an inverted trapezoidal cavity 1011, and a third column 18 is provided inside the inverted trapezoidal cavity 1011. The mortise and tenon structure includes a tenon shoulder plate 19 and a connecting plate 15 fixed to the opposite ends of the two inverted trapezoidal cavities 1011. One side of the tenon shoulder plate 19 is fixedly connected to a tenon 191, and one side of the connecting plate 15 is fixedly connected to a tenon groove 16 that matches the tenon 191. The included angle between the first column 12 and the second column 13 is β, and the value of β is in the range of 95° to 135°.
[0045] To address the problem that the connecting plates in existing baffles are single-layer plates with poor strength, frequently resulting in cracks and fractures during installation and use, the dam unit 1 of this invention comprises six cavities, each containing a column. This not only increases the strength of the dam unit 1, but the column material is also a closed-cell long-fiber reinforced rigid polyurethane composite material, further enhancing the structural stability and corrosion resistance of the dam unit 1. This not only reduces the weight of the dam unit 1, but also improves the water flow impact resistance of the cavities 1011. Furthermore, the angle β between two cavities 1011 further increases the impact resistance of the dam unit 1 and reduces water pressure and diverts water flow.
[0046] like Figure 6 As shown, the vertically connected column 101 includes two parallel cavities 1011, and the interior of both cavities 1011 is filled with core material 11.

Two inverted trapezoidal cavities 1011 are fixedly connected to the lower part of the upper triangular cavities 1011, and the interior of each cavity 1011 is filled with core material 11. Two tenons 191 with an included angle of 90° are fixedly connected to the two inclined surfaces of the upper part of the reversing connecting column 104. A mortise 16 is fixedly connected to the lower part of the reversing connecting column 104. The mortise 16 and the two tenons 191 form an included angle of 135°.
[0050] like Figure 10 As shown, the four-way connecting column 105 includes two longitudinally symmetrical cavities 1011. The two upper cavities 1011 are fixedly connected to two transversely symmetrical cavities 1011 below them, and the interior of each cavity 1011 is filled with core material 11. The outer wall of the four-way connecting column 105 is fixedly connected with two sets of symmetrical tenon and mortise structures.
[0051] It should be noted that the core material 11 filling the cavity 1011 in the connecting device 10 is the same as the column material in the dam unit 1.
[0052] like Figure 11 and Figure 12 As shown, the crossbeam 2 includes two right-angled cavities 21 at the top and two right-angled cavities 21 at the bottom, and a rectangular cavity 22 is provided between the two right-angled cavities 21 at the top and the two right-angled cavities 21 at the bottom. The interior of the crossbeam 2 is provided with a groove 23 that is compatible with the M-type fastener 5.
[0053] like Figure 2 and Figure 13 As shown, the upper part of the dam slab is fixedly connected to the eaves 6 by fastening bolts 9. Concrete dam foundation piles 8 for fixing the dam slab are provided below the dam slab. Two crossbeams 2 are provided on both the inner and outer sides of the lower part of the dam slab, and the crossbeams 2 are placed within the concrete dam foundation piles 8. One of the bottom inner and outer crossbeams 2 is fixedly connected to the concrete dam foundation pile 8 through mounting holes. Concrete is poured into the concrete dam foundation piles 8, making the crossbeams 2 and the concrete dam foundation piles 8 a single unit. Excess soil is backfilled and compacted in the area away from the water, forming a complete dam device. This device has the advantages of a robust and compact structure, convenient installation, time and labor saving, and high strength.
[0054] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
