A flood control device for water conservancy projects

Abstract

This utility model discloses a flood control device for water conservancy projects, relating to the field of water conservancy engineering technology. The flood control device includes a base plate, above which a flood control mechanism is installed: a blocking component, positioned above the base plate to block water flow; and a buffer component, positioned between the base plate and the blocking component, including a connecting pipe positioned above the base plate. A sealing ring is fitted at the top of the connecting pipe, and a movable column is inserted inside the sealing ring. When water waves impact the splicing plate, the movable column moves, causing the connecting pipe and the movable column to tilt. The friction between the rubber structure at the bottom of the movable column and the wall of the connecting pipe absorbs part of the impact force, and the spring force offsets part of the instantaneous force generated by the impact. After the water waves recede, the spring will return the movable column to its original position, thus providing a buffering effect during the impact of water waves on the splicing plate.

Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a flood control device for water conservancy projects. Background Technology

[0002] Flood barriers (or flood control barriers) are temporary or permanent protective facilities used to prevent flood intrusion. They are usually installed in areas susceptible to flooding (such as low-lying areas, underground passages, building entrances, etc.) to prevent floodwater from entering buildings, underground spaces, roads, or important facilities (such as substations, subway stations, etc.) through physical barriers, protecting the safety of internal equipment, materials, and personnel. During heavy rain or rising river levels, they delay or prevent water from flowing into sensitive areas and reduce the risk of urban flooding.

[0003] The existing Chinese utility model patent with announcement number CN222053394U discloses a flood control device for water conservancy projects, relating to the field of water conservancy engineering technology. It includes a base, a first flood control plate fixedly connected to the front side wall of the base, a second flood control plate symmetrically slidably arranged on the front side wall of the first flood control plate, an installation frame fixedly connected to the rear side wall of the first flood control plate, a transmission component rotatably connected between the upper and lower ends of the inner side of the installation frame, a telescopic rod symmetrically fixedly installed on the top of the installation frame, an installation plate fixedly connected to the top of the telescopic rod, a constraint component that engages with the transmission component fixedly connected between the two sets of installation plates, and a threaded component symmetrically rotatably connected to the rear side wall of the first flood control plate, meshing with the transmission component. Threaded blocks are symmetrically threaded onto the threaded component. By using the constraint component to limit and constrain the transmission component, the transmission component is less likely to loosen when the device is impacted by external floodwaters.

[0004] The aforementioned flood control device has an "L" shaped structure and uses a rod-like structure to increase its overall strength. However, this design lacks a buffer structure when subjected to wave impacts, which may cause the device to shift during use. Furthermore, the device may deform after prolonged use, leading to a decrease in overall structural strength. Additionally, its large size makes it very inconvenient to transport. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a flood control device for water conservancy projects, which solves the problems of inconvenient transportation and the overall strength of the non-buffered structure decreasing over time.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A flood control device for water conservancy projects includes a base plate, and a flood control mechanism is arranged above the base plate.

[0007] A blocking component, positioned above the base plate, is used to block water flow.

[0008] A buffer assembly, disposed between a base plate and a blocking assembly, includes a connecting pipe disposed above the base plate. A sealing ring is fitted at the top of the connecting pipe. A movable column is inserted inside the sealing ring. A spring is inserted outside the movable column. A transition block is fixedly installed at one end of the movable column and the connecting pipe. A limit rod is movably installed inside the transition block.

[0009] Preferably, the blocking assembly includes a limiting frame movably mounted on the right end of the base plate, a fixing plate fixedly mounted above the limiting frame, a rocker arm inserted through the top of the fixing plate, a limiting plate movably mounted at the bottom end of the rocker arm, a splicing plate inserted through the inside of the limiting frame, and a wave deflector fitted above the splicing plate.

[0010] Preferably, the limiting frame and the base plate are rotatably connected, the inner side of the limiting frame is provided with a sliding groove structure that matches the thickness of the splicing plate and the wave deflector, and the fixing plate is installed on the top of the limiting frame by bolts.

[0011] Preferably, the rocker arm is rotatably connected to the fixed plate via a threaded structure, and the bottom end of the rocker arm is rotatably connected to the limiting plate via a bearing. The limiting plate is fitted inside the sliding groove structure of the limiting frame, and the limiting plate and the limiting frame are slidably connected. The bottom end of the splicing plate is provided with a protruding structure, and the top end of the splicing plate is provided with a groove that fits into the protruding structure. One side of the anti-surge plate is provided with an upwardly sloping plate-like structure.

[0012] Preferably, the connecting pipe is rotatably connected to the bottom plate via a transition block at the bottom and a limiting rod, the inner diameter of the connecting pipe is larger than the diameter of the top opening, and the sealing ring is fitted inside the opening structure at the top of the connecting pipe.

[0013] Preferably, a rubber ring is fixed to the outer side of the disc-shaped structure at the bottom of the movable column to increase sliding damping, and the movable column and the sealing ring of the connecting pipe are both connected in a sliding manner.

[0014] Beneficial effects

[0015] This utility model provides a flood control device for water conservancy projects. Compared with the prior art, it has the following advantages:

[0016] (1) The flood control device of this water conservancy project, through the setting of the limiting frame, the sliding groove structure on both sides of the limiting frame can limit the position of the splicing plate and the wave-breaking plate. After the fixing plate is removed, the splicing plate and the wave-breaking plate can be removed by sliding, reducing the weight of the device. At the same time, after the bolts on the surface of the limiting rod are removed, the bottom plate and the limiting frame can be folded by rotating, thereby reducing the volume during transportation and facilitating transportation.

[0017] (2) The flood control device of this water conservancy project, through the setting of the movable column, through the connecting block and the limiting rod at the bottom of the connecting pipe and the top of the movable column, forms a rotating connection between the bottom of the connecting pipe and the bottom plate, and forms a rotating connection between the top of the movable column and the limiting frame. The movable column can slide inside the connecting pipe, and during the sliding process, the disc-shaped structure at the bottom of the movable column squeezes the spring. During the process of water waves hitting the splicing plate, the movable column will be moved, and the connecting pipe and the movable column will tilt. The friction between the rubber structure at the bottom of the movable column and the wall of the connecting pipe absorbs part of the impact force, and the elastic force of the spring can offset part of the force generated at the moment of impact. After the water waves recede, the spring will drive the movable column to reset during the restoration process, thus playing a buffering role during the process of water waves hitting the splicing plate.

[0023] 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.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a flood control device for water conservancy projects, including a base plate 1, and a flood control mechanism 2 is arranged above the base plate 1.

[0025] A blocking assembly 21, disposed above the base plate 1, is used to block water flow. The blocking assembly 21 includes a limiting frame 211 movably mounted on the right end of the base plate 1. A fixing plate 212 is fixedly mounted on the top of the limiting frame 211. A rocker arm 213 is inserted through the top of the fixing plate 212. A limiting plate 214 is movably mounted on the bottom end of the rocker arm 213. A splicing plate 215 is inserted through the inside of the limiting frame 211. A wave deflector 216 is fitted on the top of the splicing plate 215. The limiting frame 211 and the base plate 1 are rotatably connected. The inner side of the limiting frame 211 is provided with a connection to the splicing plate 215 and the wave deflector 214. The 6-thickness matching groove structure, the fixed plate 212 is installed on the top of the limit frame 211 by bolts, the rocker arm 213 is rotatably connected to the fixed plate 212 by a threaded structure, and the bottom end of the rocker arm 213 is rotatably connected to the limit plate 214 by a bearing. The limit plate 214 is fitted into the groove structure of the limit frame 211, and the limit plate 214 and the limit frame 211 are slidably connected. The bottom end of the splicing plate 215 is provided with a protruding structure, and the top end of the splicing plate 215 is provided with a groove that fits into the protruding structure. One side of the anti-surge plate 216 is provided with an upwardly inclined plate structure.

[0026] Specifically, the base plate 1 can restrict the position of the flood control mechanism 2. The multiple splicing plates 215 inside the limiting frame 211 and the wave deflector 216 can block the water flow. The fixing plate 212 is fixed to the top of the sliding groove structure of the limiting frame 211 by bolts. The rocker arm 213 is connected to the fixing plate 212 by a threaded structure. During the rotation of the rocker arm 213, the limiting plate 214 at the bottom of the rocker arm 213 will move downward to contact the wave deflector 216. By continuously rotating the rocker arm 213, the wave deflector 216 and the splicing plate 215 are tightly fitted together. At the same time, the inclined plate at the top of the wave deflector 216 can ensure the overall height of the device after the wave deflector 216 is tilted.

[0027] The buffer assembly 22 is disposed between the base plate 1 and the blocking assembly 21. It includes a connecting pipe 221 disposed above the base plate 1. A sealing ring 222 is fitted at the top of the connecting pipe 221. A movable column 223 is inserted inside the sealing ring 222. A spring 224 is inserted outside the movable column 223. A transition block 225 is fixedly installed at one end of the movable column 223 and the connecting pipe 221. A limit rod 226 is movably installed inside the transition block 225. The connecting pipe 221 is rotatably connected to the base plate 1 through the transition block 225 and the limit rod 226 at the bottom end. The inner diameter of the connecting pipe 221 is larger than the diameter of the top opening. The sealing ring 222 is fitted inside the opening structure at the top end of the connecting pipe 221. A rubber ring is fixed to the outside of the disc-shaped structure at the bottom end of the movable column 223 to increase sliding damping. The movable column 223 and the sealing ring 222 of the connecting pipe 221 are all slidably connected.

[0028] Specifically, the connecting pipe 221 can limit the position of the top of the spring 224 and the direction of movement of the movable column 223. The bottom of the connecting pipe 221 and the bottom of the movable column 223 are connected to the base plate 1 by the adapter block 225 and the limiting rod 226, and the top of the movable column 223 is connected to the limiting frame 211 by a rotating connection. The movable column 223 can slide inside the connecting pipe 221, and during this sliding process, the disc-shaped structure at its bottom compresses the spring 224. During the impact of water waves on the splicing plate 215, the spring 224 is... This will cause the movable column 223 to move and tilt the connecting pipe 221 and the movable column 223. The friction between the rubber structure at the bottom of the movable column 223 and the wall of the connecting pipe 221 will absorb part of the impact force, and the elastic force of the spring 224 can offset part of the force generated at the moment of impact. After the water waves recede, the spring 224 will drive the movable column 223 to return to its original position during the recovery process, thus playing a buffering role in the process of water waves hitting the splicing plate 215. At the same time, the contents not described in detail in this specification are all prior art known to those skilled in the art.

[0029] During operation, the sliding groove structure on both sides of the limiting frame 211 can restrict the position of the splicing plate 215 and the anti-surge plate 216. After removing the fixing plate 212, the splicing plate 215 and the anti-surge plate 216 can be removed by sliding, reducing the weight of the device. At the same time, after removing the bolts on the surface of the limiting rod 226, the base plate 1 and the limiting frame 211 can be folded by rotation, thereby reducing the volume during transportation and facilitating transport. The connecting block 225 at the bottom of the connecting pipe 221 and the top of the movable column 223, along with the limiting rod 226, form a rotatable connection between the bottom of the connecting pipe 221 and the base plate 1, and a connection between the top of the movable column 223 and the limiting frame 211. The rotating connection allows the movable column 223 to slide inside the connecting pipe 221. During this sliding process, the disc-shaped structure at the bottom of the movable column 223 compresses the spring 224. When water waves impact the splicing plate 215, the movable column 223 will move, causing the connecting pipe 221 and the movable column 223 to tilt. The friction between the rubber structure at the bottom of the movable column 223 and the wall of the connecting pipe 221 absorbs part of the impact force, and the elastic force of the spring 224 can offset part of the instantaneous force generated by the impact. After the water waves recede, the spring 224 will drive the movable column 223 to return to its original position during the recovery process, thus playing a buffering role in the process of water waves impacting the splicing plate 215.
