Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering, and more specifically, it relates to a water conservancy drainage and flood discharge channel. Background Technology

[0002] A flood diversion channel is an artificial or natural waterway used for flood control and drainage. Its main function is to quickly guide, divert and discharge floodwaters during rainstorms and floods, reduce flood control pressure in downstream areas and prevent floods from causing disasters.

[0003] When constructing flood discharge channels, if there are mountains, buildings, important facilities, or geologically unstable areas along the channel's path, the channel needs to bend around them. Therefore, bends are unavoidable during the construction of flood discharge channels. During flood discharge, the water flow is accelerated when passing through the straight section, but when it enters the bend section, it impacts the riverbed and slows down. Over time, this can easily damage the riverbed at the bend section.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a water conservancy dredging and flood discharge channel.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a water conservancy drainage channel, comprising a ditch, the ditch including a straight section and a curved section, the straight section being provided with a plurality of flow-damping plates arranged near the upstream of the curved section, the flow-damping plates on both sides of the straight section being staggered, the curved section being provided with a flow-blocking plate, the flow-blocking plate being located on the side wall of the curved section facing the straight section, an installation platform being fixedly connected above the ditch, the installation platform having a plurality of installation holes, a plurality of installation columns being fixedly connected to one side of the flow-blocking plate, the installation columns being slidably connected in the installation holes, the installation columns being fitted with compression springs, the compression springs also being arranged between the flow-blocking plate and the side wall of the curved section.

[0007] The present invention is further configured such that: a friction plate is provided on the side of the baffle facing away from the mounting platform, a bottom net is fixedly connected to the lower side of the friction plate, and the friction plate is connected to the baffle by fixing bolts.

[0008] The present invention is further configured such that the connection between the fixing bolt and the baffle plate is located outside the ditch.

[0009] The present invention is further configured such that: a plurality of baffles are provided on the side of the friction plate facing away from the baffle plate, and the length direction of the baffles is arranged along the depth direction of the ditch.

[0010] The present invention is further configured such that: protective plates are fixedly connected to both sides of the straight section, the flow-retarding plate is rotatably connected to the protective plates, a sliding groove is provided on the protective plates, a slider is slidably connected in the sliding groove, a support rod is provided between the slider and the flow-retarding plate, the two ends of the support rod are rotatably connected to the slider and the flow-retarding plate respectively, and a buffer spring is also provided in the sliding groove, the two ends of the buffer spring abutting against the slider and the inner wall of the sliding groove respectively.

[0011] The present invention is further configured such that: a guide rod passing through the slider is fixedly connected inside the groove, the slider slides along the guide rod, and the buffer spring is sleeved on the guide rod.

[0012] In summary, this utility model has the following beneficial effects:

[0013] Before the water enters the bend, the staggered flow deflector breaks the linear flow of the water, dissipates kinetic energy through turbulence, thereby slowing down the flow velocity and reducing the impact on the inner wall of the bend. The baffle plate can block the impact of the water flow, and since the mounting platform for the baffle plate structure is located outside the ditch, the mounting platform structure mainly bears the force, ensuring the safety of the riverbed in the bend. The compression spring helps the baffle plate to provide some buffering, thereby reducing the impact force of the water flow. Attached Figure Description

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Water conservancy dredging and flood discharge channels, such as Figure 1 and Figure 2As shown, the ditch includes a straight section and a curved section, which are interconnected. Several flow-delaying plates 1 are installed on the straight section near the upstream of the curved section, with the flow-delaying plates 1 on both sides of the straight section being staggered. Baffle plates 2 are installed on the curved section, located on the sidewall of the curved section facing the straight section. An installation platform 3 is fixedly connected above the ditch, located on the ground outside the ditch and secured to the ground by expansion bolts. The installation platform 3 has several installation holes. Several installation columns 4 are fixedly connected to one side of the baffle plates 2, and the installation columns 4 are slidably connected in the installation holes. Compression springs 5 ​​are fitted around the installation columns 4, and the compression springs 5 ​​are also installed on the sidewalls of the baffle plates 2 and the curved sections. Between the straight sections, the water flows from the straight section to the bend. Before the water enters the bend, the staggered flow-damping plate 1 breaks the linear flow of the water, dissipating kinetic energy through turbulence, thereby slowing down the flow velocity and reducing the impact on the inner wall of the bend. The baffle plate 2 can block the impact of the water flow. Since the mounting platform 3 for installing the baffle plate 2 is located outside the ditch, the mounting platform 3 mainly bears the force, ensuring the safety of the riverbed in the bend. The compression spring 5 helps the baffle plate 2 to provide some buffering, thereby reducing the impact force of the water flow. After the mounting column 4 slides to the sliding hole limit position, the mounting platform 3 supports the baffle plate 2. The above structure ensures the safety of the riverbed in the bend.

[0019] like Figure 1 and Figure 2 As shown, a friction plate 6 is provided on the side of the baffle plate 2 facing away from the mounting platform 3. A bottom net 7 is fixedly connected to the lower side of the friction plate 6. The friction plate 6 is connected to the baffle plate 2 by fixing bolts 8. Several baffles 9 are provided on the side of the friction plate 6 facing away from the baffle plate 2. The length direction of the baffles 9 is set along the depth direction of the ditch. The friction coefficient of the friction plate 6 surface is high, and the baffles 9 can also slow down the speed of the water flow through the bend. At the same time, because the water flow speed is slowed down, garbage is more likely to be retained at the bend. The bottom net 7 can collect some of the garbage in the water flow, reduce the impact of subsequent garbage on the riverbed, and also allow the staff to focus on the key points when cleaning the ditch regularly, making it convenient for the staff to clean the ditch. The connection between the fixing bolts 8 and the baffle plate 2 is located outside the ditch. This setting can avoid the fixing bolts 8 being exposed to the water flow, reduce the risk of corrosion, and facilitate maintenance and replacement.

[0020] like Figure 1 and Figure 2As shown, protective plates 10 are fixedly connected to both sides of the straight section. A flow-damping plate 1 is rotatably connected to the protective plates 10. A groove 11 is provided on the protective plate 10, and a slider 15 is slidably connected in the groove 11. A support rod 12 is provided between the slider 15 and the flow-damping plate 1, with both ends of the support rod 12 rotatably connected to the slider 15 and the flow-damping plate 1, respectively. A buffer spring 13 is also provided inside the groove 11, with both ends of the buffer spring 13 abutting against the slider 15 and the inner wall of the groove 11, respectively. The protective plate 10 serves as the supporting structure for the flow-damping plate 1, and the water flow... When impacted, the angle of the buffer plate 1 can be changed by moving the slider 15. During the rotation of the buffer plate 1, the compression spring 5 will deform, and the energy will be absorbed by the deformation, avoiding damage to the buffer plate structure caused by hard impact. A guide rod 14 passing through the slider 15 is fixedly connected in the groove 11. The slider 15 slides along the guide rod 14. The buffer spring 13 is sleeved on the guide rod 14. The guide rod 14 provides guidance for the sliding of the slider 15. The buffer spring 13 sleeved on the guide rod 14 ensures uniform force during compression and improves structural stability.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
