Description

Technical Field

[0001] This utility model relates to the field of water conservancy technology, and in particular to a stilling box culvert with multi-directional turbulence function. Background Technology

[0002] A stilling culvert is an important structure in hydraulic engineering used to control water flow velocity and dissipate water flow energy. It typically consists of two parts: a stilling basin section and a culvert section. Through its special internal structure, it converts the kinetic energy of high-speed water flow into potential energy and thermal energy, effectively preventing downstream riverbed erosion and structural damage.

[0003] In related technologies, energy dissipation culverts lack multi-directional turbulence during the energy dissipation process, which affects their energy dissipation effect. Furthermore, the fixed size of the energy dissipation orifices in energy dissipation culverts cannot be adjusted according to water flow, thus impacting their load-bearing capacity. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of related technologies, such as the lack of multi-directional turbulence and fixed energy dissipation hole size, and to propose a energy dissipation box culvert with multi-directional turbulence function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A stilling box culvert with multi-directional flow disturbance function includes a stilling box culvert body and a water pool disposed at the bottom of the stilling box culvert body, characterized in that the stilling box culvert further includes:

[0007] The primary diversion plate, the middle diversion plate, and the lower diversion plate are installed inside the stilling culvert body. The lower diversion plate is relatively close to the water tank, the primary diversion plate is relatively far from the water tank, and the middle diversion plate is located between the primary diversion plate and the lower diversion plate.

[0008] The retaining walls are arranged on the side of the primary diversion plate facing away from the middle diversion plate to form channels for the flow of water.

[0009] The first turbulence piers are arranged on the side of the middle-level diverter plate facing the primary diverter plate;

[0010] The second turbulence pier is located on the side of the primary diversion plate facing away from the middle diversion plate and between the inner wall of the stilling box culvert and the retaining wall adjacent to the inner wall of the stilling box culvert.

[0011] The first energy dissipation grille is installed on the primary diversion plate and is located between the second turbulence pier and the inner wall of the energy dissipation box culvert.

[0012] The second energy dissipation grille is installed on the top wall of the energy dissipation box culvert body;

[0013] A honeycomb cavity energy dissipation structure is installed between the middle layer diverter plate and the lower layer diverter plate;

[0014] The energy dissipation mechanism is connected to the top wall of the stilling culvert body. The energy dissipation grid controls the water flow, the energy dissipation ladder guides the water flow and increases resistance, the retaining wall forms a channel for the flowing water and controls the direction of the water flow, the turbulence pier generates multi-directional vortices, and the honeycomb cavity energy dissipation structure forms three-dimensional flow inside the cavity, generating multi-directional shear and turbulence. Due to the large number of energy dissipation cavities, it can dissipate a large amount of energy from the high-speed rapid flow.

[0015] Furthermore, energy dissipation mechanisms include:

[0016] The transmission box is connected to the opening in the top wall of the stilling box culvert body;

[0017] The servo motor is housed inside the transmission box;

[0018] The energy dissipation component is connected to the output end of the servo motor via a rotating shaft.

[0019] Connect the power supply to the servo motor. The power supply can be an external power supply or a self-contained power supply. The servo motor is controlled by the servo system. The servo motor can drive the rotating shaft to rotate, and the rotating shaft can drive the energy dissipation component.

[0020] Furthermore, the energy dissipation components include:

[0021] An eccentric wheel, with a hole at the top of its shaft that fits into the rotating shaft;

[0022] The ring frame is connected to the rotating eccentric wheel;

[0023] The large perforated plate has its top hinged to the bottom of the ring frame.

[0024] Fixed orifice plates are respectively installed on opposite sides of the large orifice plate, and the fixed orifice plates are slidably connected to the large orifice plate. The rotating shaft is rotatably sleeved with the transmission box, and the fixed orifice plates are fixedly connected to the side of the primary diverter plate opposite to the middle diverter plate.

[0025] The rotating shaft drives two eccentric wheels to rotate. The eccentric structure of the eccentric wheels and the rotating shaft allows the eccentric wheels to rotate upwards as a whole. The ring frame is set to rotate with the eccentric wheels via bearings. As the eccentric wheels rotate, they drive the ring frame to move upwards. The ring frame, in turn, drives the large perforated plate to move upwards. By adjusting the positions of the large perforated plate and the fixed perforated plate, the size of the energy dissipation holes between them can be adjusted. The rotating shaft is set to rotate with the transmission box via bearings, ensuring the smoothness of the shaft's rotation. The fixed perforated plate is thus fixed in place.

[0026] Furthermore, the stilling culvert also includes:

[0027] The energy dissipation ladder is located on the side of the intermediate diversion plate facing the primary diversion plate, and is arranged opposite to the first energy dissipation grid. The energy dissipation ladder can dissipate energy from the downstream water.

[0028] Furthermore, an inlet is provided at the top of the stilling culvert body, and a second energy dissipation grid is bolted to the inlet. The first energy dissipation grid is bolted to the inner wall of the stilling culvert body. The second energy dissipation grid can be a large-diameter energy dissipation grid, which can reduce the impact on water flow while dissipating energy.

[0029] Furthermore, both sides of the pool are connected to water outlet pipes, and the middle and lower diversion plates each have a connecting port. The water outlet pipes are used to discharge the water after energy dissipation, and the connecting ports of the middle and lower diversion plates facilitate water flow.

[0030] Beneficial effects:

[0031] 1. The three-layer structure of primary diversion plate, middle diversion plate and lower diversion plate causes the water flow to form multiple direction changes and counterflows in the box culvert. The energy dissipation grid controls the water flow, the energy dissipation ladder guides the water flow and increases resistance, the retaining wall forms a channel for the flow of water and controls the direction of the water flow, and the turbulence pier is set at the turning point of the channel to generate multi-directional vortices. The water flow submerges into the energy dissipation cavity of the honeycomb cavity energy dissipation structure, forming a three-dimensional flow inside the cavity, generating multi-directional shear and turbulence. Due to the large number of energy dissipation cavities, a large amount of energy of high-speed rapid flow can be dissipated.

[0032] 2. The servo motor can drive the eccentric wheel to rotate through the shaft. The eccentric wheel can drive the large perforated plate to rise and fall through the ring frame. By adjusting the position of the large perforated plate and the fixed perforated plate, the size of the energy dissipation hole between them can be adjusted.

[0033] In this utility model: the energy dissipation grid controls the water flow, the energy dissipation ladder guides the water flow and increases resistance, the retaining wall forms a channel for the flow of water and controls the direction of the water flow, the turbulence pier generates multi-directional vortices, and the honeycomb cavity energy dissipation structure forms three-dimensional flow inside the cavity, generating multi-directional shear and turbulence. Due to the large number of energy dissipation cavities, a large amount of energy of high-speed rapid flow can be dissipated. Attached Figure Description

When a component is described as "connected to" another component, it can be directly connected to the other component or there may be an intervening component present.

[0043] Furthermore, the descriptions involving "first," "second," etc., in the embodiments of this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0044] To address the technical deficiencies in related technologies, this embodiment provides a stress-reducing box culvert with multi-directional turbulence function. For example... Figures 1 to 4 As shown, the stilling culvert includes a stilling culvert body 1 and a water pool 2 cast at the bottom of the stilling culvert body 1. The stilling culvert with multi-directional flow disturbance function also includes:

[0045] A multi-layer flow channel energy dissipation component includes a primary diversion plate 3, a middle diversion plate 4, and a lower diversion plate 5, which are disposed within the main body 1 of the energy dissipation box culvert. The lower diversion plate 5 is relatively close to the water tank 2, the primary diversion plate 3 is relatively far from the water tank 2, and the middle diversion plate 4 is located between the primary diversion plate 3 and the lower diversion plate 5.

[0046] The turbulence-type energy dissipation component includes a retaining wall 6, a first turbulence pier 7, a second turbulence pier 71, an energy dissipation ladder 8, a first energy dissipation grid 9, a second energy dissipation grid 91, and a honeycomb cavity energy dissipation structure 10.

[0047] Among them, retaining walls 6 are arranged on the side of the primary diversion plate 3 facing away from the middle diversion plate 4 to form a channel for water flow. First turbulence piers 7 are arranged on the side of the middle diversion plate 4 facing the primary diversion plate 3. Second turbulence piers 71 are located on the side of the primary diversion plate 3 facing away from the middle diversion plate 4 and between the inner wall of the stilling culvert body 1 and the retaining walls 6 adjacent to the inner wall of the stilling culvert body 1. First energy dissipation grids 9 are formed in the primary diversion plate 3, and are located between the second turbulence piers 71 and the inner wall of the stilling culvert body 1. Second energy dissipation grids 91 are formed on the top wall of the stilling culvert body 1. A honeycomb cavity type energy dissipation structure 10 is set between the middle diversion plate 4 and the lower diversion plate 5; an energy dissipation mechanism is connected to the top wall of the stilling culvert body 1.

[0048] The first energy dissipation grid 9 and the second energy dissipation grid 91 control the water flow, the energy dissipation ladder 8 guides the water flow and increases resistance, the retaining wall 6 forms a channel for the flow of water and controls the direction of the water flow, the turbulence pier generates multi-directional vortices, and the honeycomb cavity energy dissipation structure 10 forms a three-dimensional flow inside the cavity, generating multi-directional shear and turbulence. Due to the large number of energy dissipation cavities, a large amount of energy of high-speed rapid flow can be dissipated.

[0049] To adjust the size of the energy dissipation orifice, such as Figure 3 As shown, the energy dissipation mechanism includes a transmission box 11, a servo motor 12, a rotating shaft 13, and an energy dissipation assembly. The transmission box 11 is connected to an opening in the top wall of the energy dissipation box body 1. The servo motor 12 is housed within the transmission box 11. The energy dissipation assembly is connected to the output end of the servo motor 12 via the rotating shaft 13.

[0050] The power supply of the servo motor 12 is turned on. The power supply can be an external power supply or a self-provided power supply. The servo motor 12 is controlled by the servo system. The servo motor 12 can drive the rotating shaft 13 to rotate. The rotating shaft 13 can drive the energy dissipation component.

[0051] For example, in order to adjust the position of the large perforated plate 16, such as Figure 3As shown, the energy dissipation assembly includes an eccentric wheel 14, a ring frame 15, a large perforated plate 16, and a fixed perforated plate 17. Two eccentric wheels 14, two ring frames 15, and two large perforated plates 16 are provided, while four fixed perforated plates 17 are provided. The hole at the top of the eccentric wheel 14's shaft is keyed to the surface of the rotating shaft 13. The surface of the eccentric wheel 14 is rotatably fitted with the hole in the ring frame 15. The bottom end of the ring frame 15 is hinged to the top of the large perforated plate 16. The two sides of the large perforated plate 16 are slidably connected to the sides of the two fixed perforated plates 17, respectively. The rotating shaft 13 can drive the two eccentric wheels 14 to rotate. The eccentric structure of the eccentric wheel 14 and the rotating shaft 13 allows the eccentric wheel 14 to rotate upwards as a whole. The ring frame 15 is rotatably set with the eccentric wheel 14 via bearings. During the rotation of the eccentric wheel 14, it can drive the ring frame 15 to move upwards, which in turn drives the large perforated plate 16 to move upwards. By adjusting the positions of the large perforated plate 16 and the fixed perforated plates 17, the size of the energy dissipation holes between them can be adjusted.

[0052] To increase the stability of energy dissipation mechanisms, such as Figure 3 As shown, the rotating shaft 13 is rotatably sleeved with the transmission box 11, and the fixed perforated plate 17 is fixedly connected to the side of the primary diverter plate 3 facing away from the middle diverter plate 4. The rotating shaft 13 is rotatably set with the transmission box 11 through bearings to ensure the smooth rotation of the rotating shaft 13, and the fixed perforated plate 17 is fixed.

[0053] In order to facilitate energy dissipation, such as Figure 2 As shown, the energy dissipation ladder 8 is located on the side of the intermediate diversion plate 4 facing the primary diversion plate 3, and the energy dissipation ladder 8 is arranged opposite to the first energy dissipation grid 9. The number of first energy dissipation grids 9 is the same as the number of energy dissipation ladders 8, and the energy dissipation ladder 8 can dissipate energy from the downstream water.

[0054] To increase the energy dissipation effect, such as Figure 2 As shown, the top of the stilling culvert body 1 has a water inlet, and the second energy dissipation grid 91 is bolted to the water inlet. The first energy dissipation grid 9 is bolted to the inner wall of the stilling culvert body 1. The second energy dissipation grid 91 can be a large-diameter energy dissipation grid, which can reduce the impact on water flow while dissipating energy.

[0055] To facilitate the drainage of water from pool 2, such as Figure 2 As shown, both sides of the water tank 2 are connected to water outlet pipes, and the middle layer diversion plate 4 and the lower layer diversion plate 5 are provided with connecting ports. The water outlet pipes are used to discharge the water after energy dissipation, and the connecting ports of the middle layer diversion plate 4 and the lower layer diversion plate 5 facilitate the flow of water.

[0056] It should be noted that the specific model of servo motor 12 used should be selected by those skilled in the art, and the above information regarding servo motor 12 is existing technology, so this solution will not elaborate on it.

[0057] The operating steps of this utility model are as follows: Water flows through the inlet of the stilling culvert body 1 and enters the interior of the stilling culvert body 1. It first falls on the primary diversion plate 3. The three-layer structure of the primary diversion plate 3, the middle diversion plate 4, and the lower diversion plate 5 forms three cavities inside the stilling culvert body 1. The water on the primary diversion plate 3 flows to both sides, passing through the energy dissipation grid, the retaining wall 6, and the turbulence piers. Then, it exits from the outlet of the primary diversion plate 3, controlled by the energy dissipation grid, and falls onto the energy dissipation ladder 8. During this process, the energy dissipation grid controls the water flow, the energy dissipation ladder 8 guides the water flow and increases resistance, the retaining wall 6 forms a channel for the flowing water and controls the direction of the water flow, and the turbulence piers are set at the turning points to generate multi-directional vortices. After the water flows to the middle diversion plate 4, it descends through the pipe to the energy dissipation cavity of the honeycomb cavity energy dissipation structure 10. In the process, a three-dimensional flow is formed inside the cavity, generating multi-directional shear and turbulence. Due to the large number of energy dissipation cavities, a large amount of energy of the high-speed jet can be dissipated. When control is required, the power supply of the servo motor 12 is turned on. The power supply can be an external power supply or a self-provided power supply. The servo motor 12 is controlled by the servo system. The servo motor 12 can drive the rotating shaft 13 to rotate. The rotating shaft 13 can drive the two eccentric wheels 14 to rotate. The eccentric structure of the eccentric wheel 14 and the rotating shaft 13 allows the eccentric wheel 14 to be raised as a whole. The ring frame 15 is rotated with the eccentric wheel 14 through the bearing. During the rotation of the eccentric wheel 14, it can drive the ring frame 15 to move upward. The ring frame 15 can drive the large perforated plate 16 to move upward. By adjusting the position of the large perforated plate 16 and the fixed perforated plate 17, the size of the energy dissipation hole between them can be adjusted.

[0058] The above description is only a part or preferred embodiment of this utility model. Neither the text nor the drawings should limit the scope of protection of this utility model. All equivalent structural transformations made using the content of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
