Description

Technical Field

[0001] This utility model relates to the field of hydraulic model experiment technology, and in particular to a convenient switching energy dissipation device based on a 3D printed spillway model. Background Technology

[0002] With the increasing sophistication of 3D printing technology, hydraulic model experiments are increasingly adopting 3D printing to create experimental models. 3D printing shortens the model-making process and improves model accuracy. However, since numerical simulations only provide theoretical references, actual experiments are more informative. Therefore, energy dissipation assessment experiments typically require multiple sets of predetermined energy dissipation schemes. The model surface is typically cement. Traditional methods of pasting energy-efficient panels, such as rectangular or T-shaped energy dissipation piers, either involve printing them directly along with the surface during the 3D printing process or cutting them into wooden panels and pasting them onto the cement model surface. This results in significant time and cost when switching energy dissipation schemes.

[0003] There are two main approaches to setting up traditional energy dissipation schemes: (1) While making the model, the arrangement of the energy dissipation piers is completely fixed to the bottom of the stilling pool; (2) After completing the overall arrangement of the model, the energy dissipation piers are remade and fixed by pasting or nailing into the bottom of the stilling pool. Although the above two methods can obtain a stable and compliant combination of energy dissipation schemes, they are not conducive to conducting experiments on the same model to recombine different energy dissipation schemes. If the energy dissipation effect is not obvious after numerical simulation using FLOW-3D, the energy dissipation piers need to be rearranged and recombined. This requires leveling or removing the installed energy dissipation piers, which will consume a lot of experimental time and a lot of experimental costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, a convenient energy dissipation device based on a 3D-printed spillway model is provided. This device solves the problem of the inability to quickly switch energy dissipation scheme combinations in existing technologies, and also addresses the issue of the significant time and cost required for switching energy dissipation schemes in actual experiments.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a convenient energy dissipation scheme switching device based on a 3D printed spillway model. The energy dissipation scheme switching device is detachably installed inside the 3D printed spillway model. The spillway model has side walls and stilling basins. When the spillway model is printed, a stilling basin section is reserved for installing the energy dissipation component installation slot for installing the energy dissipation scheme switching device. The energy dissipation scheme switching device includes a rectangular block near the upper discharge section of the spillway model. Several hexagonal blocks are detachably connected to the side of the rectangular block away from the discharge section. The rectangular block and the several hexagonal blocks cooperate to fill the stilling component installation slot. Hook and tenon slots are opened on the top of the rectangular block and the hexagonal blocks. Several energy dissipation pier components are detachably connected in the hook and tenon slots.

[0006] Preferably, the rectangular blocks and the hexagonal blocks are separated by a number of triangular blocks.

[0007] Preferably, the hook and tenon slot is provided with a T-shaped groove, the inner wall of the hook and tenon slot is inclined and the groove cross section of the hook and tenon slot is trapezoidal, for inclined insertion of the energy dissipation block assembly.

[0008] Preferably, the energy dissipation block assembly includes a plurality of toe blocks installed in the hook-and-hook slots on the rectangular block.

[0009] Preferably, the energy dissipation block assembly includes several rectangular blocks installed in the hook-and-loop slots on the hexagonal block.

[0010] Preferably, the energy dissipation block assembly includes several T-shaped blocks installed on hexagonal blocks and hooked into tenon slots.

[0012] The beneficial effects of this utility model are:

[0013] This invention features a pre-reserved groove for installing the convenient energy dissipation scheme switching device before model construction. The energy dissipation device, composed of rectangular and hexagonal modules, can be flexibly moved and combined. An energy dissipation block can be inserted into the top of the hexagonal module, while the bottom is a smooth plane. Different energy dissipation schemes can be combined by switching the top and bottom. In addition, the groove at the front of the device provides more possibilities for the diverse combinations of energy dissipation schemes. In summary, the simple and versatile energy dissipation scheme switching saves a lot of experimental time; the mortise and tenon structure for detachable energy dissipation block installation saves experimental costs.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1-6 As shown, a convenient energy dissipation switching device based on a 3D-printed spillway model is disclosed. The energy dissipation switching device is detachably installed within the 3D-printed spillway model. The spillway model has sidewalls 8 and stilling basins 7. During printing, a stilling basin 7 section has a pre-reserved stilling component mounting slot 6 for installing the energy dissipation switching device. The energy dissipation switching device includes a rectangular block 1 near the spillway model's upper discharge section 11. Several hexagonal blocks 2 are detachably connected to the side of the rectangular block 1 away from the discharge section 11. The rectangular block 1 and the hexagonal blocks 2 cooperate to fill the stilling component mounting slot 6. Hook-and-groove slots 3 are provided on the top of both the rectangular block 1 and the hexagonal blocks 2. Several energy dissipation pier components 4 are detachably connected within the hook-and-groove slots 3. This embodiment is as follows: (See attached diagram) Figure 1As shown, the device of this utility model is installed inside the stilling basin 7. Before 3D printing, a scaled-down model of the spillway needs to be created in CAD. A groove at least 20cm deep is reserved on the stilling basin slab where energy dissipation measures are required. The horizontal and vertical dimensions of the groove need to be determined according to the specific size of the stilling basin. The basic principle is to create a rectangular groove with a length of 4 / 5 of the length of the central axis of the shortest cross-section as the reference plane and a width of 4 / 5 of the width of the stilling basin. This maximizes the energy dissipation area while ensuring the reliability of the experimental results. A wider area allows for more energy dissipation measures and thus ensures the diversity of energy dissipation schemes. Rectangular block 1 constitutes the front end of the device and is connected to hexagonal block 2, as shown in the attached diagram. Figure 2 As shown, the energy dissipation switching device on the spillway model is installed inside the stilling basin 7. The device covers more than 80% of the stilling basin's surface, thus ensuring that the aforementioned requirements are met. (See attached diagram.) Figure 3 As shown, in this device, the insertion depth of all energy dissipation block components 4 into the groove is 1 / 2 of the total height of the device.

[0023] Preferably, the rectangular block 1 and the several hexagonal blocks 2 are separated by several triangular blocks. The gaps between different hexagonal blocks 2 are filled with triangular blocks to enhance the stability of the overall structure. At the same time, mud or other materials can be filled as needed to enhance the test effect.

[0024] Preferably, the hook-and-groove slot 3 is provided with a T-shaped groove, the inner wall of the hook-and-groove slot 3 is inclined, and the groove cross-section of the hook-and-groove slot 3 is trapezoidal 10, for inclined insertion into the energy dissipation pier component 4. The function of the hook-and-groove slot 3 is to cooperate with the energy dissipation pier component 4 to form a mortise and tenon structure, thereby fixing and strengthening the flood resistance of the model during testing. Figure 5 As shown, the inclined inner wall of the T-shaped groove facilitates the inclined insertion of the energy dissipation pier assembly into the groove, achieving a more fitting tenon-and-mortise insertion.

[0025] Preferably, the energy dissipation block assembly 4 includes a plurality of toe blocks 41 for mounting in the hook-and-groove slots 3 on the rectangular block 1. In use, the toe blocks 41 are only mounted in the hook-and-groove slots 3 on the rectangular block 1, such as... Figure 6 As shown, the toe pier 41 is based on the traditional energy dissipation pier, and is equipped with a hook pad tenon plug that cooperates with the hook pad tenon slot 3. The plug is preferably located at the bottom of the toe pier 41. The top of the toe pier 41 is a right trapezoid with a length of 3 / 5 of the length of the rectangular wooden block and a width of 1 / 2 of the length of the rectangular wooden block. The hypotenuse is in contact with the model slope that enters the energy dissipation pool 7, so as to ensure that the water flow enters the energy dissipation pool in a form with better energy dissipation effect without washing away the energy dissipation pier.

[0026] Preferably, the energy dissipation block assembly 4 includes a plurality of rectangular blocks 42 for mounting on the hexagonal block 2 and hooking into the tenon slot 3, as shown in the attached figure. Figure 6 As shown, regardless of whether the A-shaped energy dissipation piers 41 are installed in the rectangular block 1, the water flow discharged from the spillway gate will arrive at the stilling basin 7, where energy dissipation work needs to be carried out. Therefore, several rectangular piers 42 need to be installed on the hexagonal block at the rear of the device to achieve the purpose of energy dissipation, so that the water flow can flow out of the spillway at a lower speed, thereby reducing the damage of the water flow to the hydraulic structure while achieving energy dissipation.

[0027] Preferably, the energy dissipation pier assembly 4 includes several T-shaped piers 43 for mounting on the hexagonal block 2 and hooking into the tenon slot 3. Similarly, this device is a flood discharge channel test device, in which various rectangular piers 42 or T-shaped piers 43 are installed and coordinated with each other to conduct experiments and achieve the best effect of this device.

[0028] Preferably, the hook-and-pad tenon slot 3 is provided with a insertion hole, and the toe block 41, rectangular block 42 and T-shaped block 43 are all provided with plugs that cooperate with the hook-and-pad tenon slot 3. The energy dissipation block assembly 4 cooperates with the hook-and-pad tenon slot 3 to form a mortise and tenon structure. The mortise and tenon structure can include a variety of different fits. In this embodiment, the preferred solution is to provide a hook-and-pad tenon plug that cooperates with the hook-and-pad tenon slot 3 at the bottom of the energy dissipation block assembly 4. The plug cooperates with the inner bottom wall of the hook-and-pad tenon slot 3 to achieve mortise and tenon connection and fixation. At the same time, this embodiment is not limited to installing plugs or opening insertion holes on the energy dissipation block assembly 4 in various positions to cooperate with the hook-and-pad tenon slot 3 to achieve mortise and tenon connection and fixation.

[0029] The working principle of this application is as follows: First, a scaled model of the spillway is established in a pre-printed CAD before 3D printing, and a spacer 6 is reserved for installing the energy dissipation device. Then, the scaled model of the spillway is obtained by 3D printing. The energy dissipation device is installed in the spacer 6 in the spillway model. Different flood discharge experiments are conducted by installing different combinations of energy dissipation pier components 4.

[0030] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
