Description

Technical Field

[0001] The utility model relates to the technical field of spillways, in particular to an energy dissipation device at an outlet of a spillway of a silt dam. Background Art

[0002] At the same time, the dam land is mainly formed by the accumulation of topsoil from the slope of the small watershed. It contains a large amount of organic matter such as livestock manure, dead branches and leaves. The soil is fertile, with sufficient water and strong drought resistance, making it a basic farmland with high and stable yields. The spillway outlet is mainly a structure used to prevent dam flooding. When the water level is high, excess water will be discharged through the spillway.

[0003] The existing application number is 202223586238.6, which is an energy dissipation device at the outlet of the spillway of a silt dam. This technical solution dissipates energy of the water flow through an arc wall and an arc baffle. When the overflowing water flow is large, the impact force of the water flow also increases. Since the energy dissipation device is used for the silt dam, there may even be solids such as silt and soil in the water flow, which increases the mass of the water flow and further increases the impact force of the water flow. However, the rear end of the arc baffle of this technical solution is only connected to the flow channel at the bottom, and both sides of the tail end of the arc baffle are not involved in the connection, resulting in a relatively weak structure of the arc baffle. Although the subsequent four arc baffles are subject to a smaller impact force because the water flow has been dissipated, the two arc baffles closest to the outlet are subject to a larger impact force, resulting in a higher probability of damage to the two arc baffles closest to the outlet. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide an energy dissipation device at the spillway outlet of a silt dam to solve the technical problems mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an energy dissipation device at the outlet of a silt dam spillway, comprising a base and an outer shell, a bracket connected to the inside of the outer shell, and a filter plate connected to one side of the bracket, a spring connected between the bracket and the filter plate, an energy dissipation wheel connected to the inside of the outer shell, and an eccentric wheel sleeved on the outside of the energy dissipation wheel, and a first energy dissipation groove and a second energy dissipation groove are provided on the top of the base.

[0006] By adopting the above technical solution, the water flow and the silt are separated by the filter plate, thereby reducing the impact force of the subsequent water flow and playing a certain energy dissipation role. The water flow pushes the energy dissipation wheel to rotate in the process of falling into the first energy dissipation groove. After the energy dissipation wheel rotates, it drives the eccentric wheel to rotate. After the eccentric wheel rotates, it resists the filter plate. At this time, the spring cooperates to make the filter plate vibrate back and forth up and down, thereby preventing the filter plate from being blocked by silt.

[0007] Furthermore, the spring is externally sleeved with a waterproof sheath, and the waterproof sheath is made of rubber material.

[0008] By adopting the above technical solution, the filter plate vibrates up and down to prevent the filter plate from being blocked by silt. At the same time, the spring is protected by the waterproof sheath to prevent the spring from being blocked by silt.

[0009] Furthermore, the second energy dissipation groove is serpentine-shaped, and the first energy dissipation groove is connected to the second energy dissipation groove.

[0010] By adopting the above technical solution, since the second energy dissipation groove is serpentine, the water flow in the second energy dissipation groove reciprocates and interweaves in the first energy dissipation groove, and the water flow in the second energy dissipation groove collides with the water flow in the first energy dissipation groove, thereby effectively reducing the subsequent impact force of the water flow.

[0011] Furthermore, the eccentric wheel abuts against the filter plate, and the filter plate is slidably connected to the bracket.

[0012] By adopting the above technical solution, the energy dissipation wheel rotates and drives the eccentric wheel to rotate. The eccentric wheel rotates and contacts the filter plate. At this time, the spring cooperates to make the filter plate vibrate up and down.

[0013] Furthermore, the top of the filter plate is sloped.

[0014] By adopting the above technical solution, the sludge flows toward the silt discharge groove through the slope of the filter plate and is discharged through the silt discharge groove, while the water passes through the filter plate and flows downward into the first energy dissipation groove.

[0015] Furthermore, the eccentric wheel and the energy dissipation wheel are both rotatably connected to the outer shell.

[0016] By adopting the above technical solution, the water flows downward into the first energy dissipation groove and pushes the energy dissipation wheel to rotate, and the energy dissipation wheel drives the eccentric wheel to rotate after the rotation.

[0017] Furthermore, the shell is connected to the top of the base, a flood spillway is provided on one side of the shell, and a silt discharge trough is connected to the other side of the shell.

[0018] By adopting the above technical solution, water flows into the shell through the overflow port, and the water is filtered by the filter plate. At this time, the silt flows toward the silt discharge trough through the slope of the filter plate and is discharged through the silt discharge trough.

[0019] In summary, the utility model mainly has the following beneficial effects:

[0020] 1. The utility model separates water flow from silt through the filter plate by setting the energy dissipation wheel, eccentric wheel, filter plate and spring, thereby reducing the impact force of subsequent water flow and playing a certain energy dissipation role. The water flow pushes the energy dissipation wheel to rotate in the process of falling into the first energy dissipation groove. After the energy dissipation wheel rotates, it drives the eccentric wheel to rotate. After the eccentric wheel rotates, it abuts against the filter plate. At this time, the spring cooperates to make the filter plate vibrate up and down, thereby preventing the filter plate from being blocked by silt; by pre-separating part of the silt, it plays an energy dissipation role and reduces the difficulty of cleaning the device;

[0021] 2. The utility model diverts the water flow through the first energy dissipation groove and the second energy dissipation groove by setting the first energy dissipation groove and the second energy dissipation groove. Since the second energy dissipation groove is serpentine, the water flow in the second energy dissipation groove is reciprocated and interspersed in the first energy dissipation groove. The water flow in the second energy dissipation groove collides with the water flow in the first energy dissipation groove, thereby effectively reducing the subsequent impact force of the water flow; the energy dissipation effect is good.

[0027] 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. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0028] The following describes an embodiment of the utility model based on its overall structure.

[0029] An energy dissipation device at the outlet of a silt dam spillway, such as Figure 1-Figure 4As shown, it includes a base 1 and a shell 2, a bracket 11 is connected inside the shell 2, a filter plate 8 is connected to one side of the bracket 11, a spring 10 is connected between the bracket 11 and the filter plate 8, and the filter plate 8 vibrates back and forth up and down, thereby preventing the filter plate 8 from being blocked by silt; a waterproof sheath 9 is sleeved on the outside of the spring 10, and the waterproof sheath 9 is made of rubber material. The spring 10 is protected by the waterproof sheath 9 to prevent the spring 10 from being blocked by silt; an energy dissipation wheel 6 is connected inside the shell 2, and an eccentric wheel 7 is sleeved on the outside of the energy dissipation wheel 6, and the water flow drives the energy dissipation wheel 6 to rotate. After the energy dissipation wheel 6 rotates, the eccentric wheel 7 drives the rotation. After the eccentric wheel 7 rotates, it counteracts the filter plate 8 to make the filter plate 8 vibrate back and forth up and down, and a first energy dissipation groove 3 and a second energy dissipation groove 12 are opened on the top of the base 1, and the first energy dissipation groove 3 is connected to the second energy dissipation groove 12, and the water flow is diverted through the first energy dissipation groove 3 and the second energy dissipation groove 12, thereby effectively reducing the subsequent impact force of the water flow.

[0030] See also Figure 1 and Figure 2 In the above embodiment, the shell 2 is connected to the top of the base 1, a flood overflow port 5 is provided on one side of the shell 2, and a silt discharge groove 4 is connected to the other side of the shell 2. The top of the filter plate 8 is sloped, and the water flows into the shell 2 through the flood overflow port 5. At this time, the water flow is filtered by the filter plate 8. At this time, the silt flows toward the silt discharge groove 4 through the slope of the filter plate 8 and is discharged through the silt discharge groove 4.

[0031] See also Figure 1-Figure 4 In the above embodiment, the second energy dissipation groove 12 is serpentine. Since the second energy dissipation groove 12 is serpentine, the water flow in the second energy dissipation groove 12 is reciprocated and interspersed in the first energy dissipation groove 3, and the water flow in the second energy dissipation groove 12 collides with the water flow in the first energy dissipation groove 3, thereby effectively reducing the subsequent impact force of the water flow; the eccentric wheel 7 is in contact with the filter plate 8, and the filter plate 8 is slidingly connected to the bracket 11. The eccentric wheel 7 and the energy dissipation wheel 6 are both rotatably connected to the outer shell 2. After the energy dissipation wheel 6 rotates, it drives the eccentric wheel 7 to rotate. After the eccentric wheel 7 rotates, it abuts against the filter plate 8. At this time, the spring 10 cooperates to make the filter plate 8 vibrate reciprocatingly up and down, thereby preventing the filter plate 8 from being blocked by silt.

[0032] The implementation principle of this embodiment is as follows: first, water flows into the interior of the housing 2 through the overflow port 5, and at this time, the water flows through the filter plate 8. At this time, the silt flows toward the silt discharge groove 4 through the slope of the filter plate 8 and is discharged through the silt discharge groove 4, while the water flows downward through the filter plate 8 into the first energy dissipation groove 3. During this period, the water flow drives the energy dissipation wheel 6 to rotate, and the energy dissipation wheel 6 drives the eccentric wheel 7 to rotate after rotating. After the eccentric wheel 7 rotates, it abuts against the filter plate 8. At this time, the spring 10 is cooperated to make the filter plate 8 vibrate up and down reciprocatingly, thereby preventing the filter plate 8 from being blocked by silt. At the same time, the spring 10 is protected by the waterproof sheath 9 to prevent the silt from blocking the spring 10. After the water flows into the first energy dissipation groove 3, the water flow is diverted through the first energy dissipation groove 3 and the second energy dissipation groove 12. Since the second energy dissipation groove 12 is serpentine, the water flow in the second energy dissipation groove 12 is reciprocated and interspersed in the first energy dissipation groove 3, and the water flow in the second energy dissipation groove 12 collides with the water flow in the first energy dissipation groove 3, thereby effectively reducing the subsequent impact force of the water flow.
