Description
Technical Field
[0001] This utility model belongs to the field of water conservancy engineering technology, specifically relating to a flood discharge structure for water conservancy projects. Background Technology
[0002] Hydraulic engineering projects are engineering works constructed to control and regulate surface water and groundwater in nature to achieve the goals of mitigating harm and promoting benefits. They are also called water engineering projects. Water is a precious resource essential for human production and life, but its natural state does not fully meet human needs. Only by constructing hydraulic engineering projects can water flow be controlled, floods prevented, and water volume regulated and distributed to meet the water needs of people's lives and production. Hydraulic engineering projects require the construction of various types of hydraulic structures, such as dams, dikes, spillways, sluice gates, intakes, canals, ferries, raft channels, and fishways, to achieve their objectives.
[0003] Problems with existing technology:
[0004] When existing flood discharge structures in water conservancy projects are in use, floodwaters directly enter the flood discharge channel when the gates are opened. Since floodwaters usually contain sediment, sediment accumulates at the bottom of the flood discharge channel, thus affecting the flood discharge effect of the flood discharge structure. In addition, the gate opening and closing operation of existing flood discharge structures in water conservancy projects is not convenient enough. Utility Model Content
[0005] The purpose of this utility model is to provide a flood discharge structure for water conservancy projects. Under the action of the diversion plate installed inside the flood discharge channel and the guide component and the storage component arranged in sequence on one side of the flood discharge channel, the silt in the flood can be filtered into the internal storage component through the guide component, thereby avoiding the blockage of the flood discharge channel and affecting the flood discharge effect.
[0006] The specific technical solution adopted by this utility model is as follows:
[0007] A flood discharge structure for a water conservancy project includes a flood discharge channel, wherein a diversion plate and a baffle are fixedly installed inside the flood discharge channel;
[0008] A water-blocking mechanism is provided at one end of the flood discharge channel, and a diversion mechanism is provided on one side of the flood discharge channel;
[0009] The flow diversion mechanism includes a guiding component and a flow storage component;
[0010] The guide assembly includes a pipe and a helical rod, with a fixing bracket fixedly installed inside the pipe and a turbine blade fixedly installed outside the helical rod;
[0011] The flow storage assembly includes a first water storage tank and a filter plate. One side of the first water storage tank is fixedly connected to a second water storage tank via a connecting pipe, and the other side of the second water storage tank is fixedly connected to a return water channel.
[0012] The two ends of the guide component are fixedly connected to the flood discharge channel and the storage component, respectively. The diversion plate is conical and located on one side of the guide component. A filter screen is provided inside the diversion plate.
[0013] The fixing frame is provided in two sets, and the screw rod is rotatably installed between the two sets of fixing frames.
[0014] One end of the pipe is connected to the flood discharge channel, so that the water flow drives the turbine blades to rotate the screw rod inside the fixed frame.
[0015] Both the first and second water storage tanks are fixedly equipped with filter plates, and the first water storage tank is fixedly connected to the guide assembly.
[0016] The water-blocking mechanism includes a gantry, an opening and closing mechanism is fixedly installed on the top of the gantry, and a mounting base is fixedly installed on the bottom of the opening and closing mechanism.
[0017] The opening and closing mechanism includes a motor, a housing, and a bracket. The motor drives a reduction gearbox to rotate a second gear. A first gear is rotatably mounted on the bottom of the bracket, and the first gear is threadedly installed with a screw.
[0018] The gearbox drives the first gear to rotate via the second gear, which in turn causes the screw to drive the mounting base and the gate to move vertically.
[0019] The technical effects achieved by this utility model are as follows:
[0020] This invention utilizes a device installed on both sides of a flood discharge channel, with a component installed inside the channel and a component fixedly installed at one end. This device effectively blocks sediment from entering the channel, allowing some floodwater to enter. The sediment is then filtered through the internal structure and further filtered before returning to the channel. Therefore, this device effectively prevents flood discharge channel blockage caused by sediment carried by floodwater, thus improving the flood discharge efficiency of the flood discharge structure.
[0021] This utility model, by installing on the top of the device and fixing it on the top of the device, allows the drive to rotate during startup, thereby causing vertical movement. Simultaneously, by driving synchronous movement, the flood discharge structure can be conveniently opened and closed. Attached Figure Description

[0029] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0030] like Figure 1-5 As shown, a flood discharge structure for a water conservancy project includes a flood discharge channel 1, and a diversion plate 4 and a baffle 5 are fixedly installed inside the flood discharge channel 1.
[0031] A water-blocking mechanism 2 is installed at one end of the flood discharge channel 1, and a diversion mechanism 3 is installed on one side of the flood discharge channel 1;
[0032] The flow diversion mechanism 3 includes a guide component 31 and a flow storage component 32;
[0033] The guide assembly 31 includes a pipe 311 and a helical rod 314. A fixing bracket 312 is fixedly installed inside the pipe 311, and a turbine blade 313 is fixedly installed outside the helical rod 314.
[0034] The flow storage component 32 includes a first water storage tank 321 and a filter plate 322. One side of the first water storage tank 321 is fixedly connected to a second water storage tank 324 via a connecting pipe 323, and the other side of the second water storage tank 324 is fixedly connected to a return water channel 325.
[0035] See attached document Figure 1 , Figure 2 and Figure 3 In this embodiment, the two ends of the guide component 31 are fixedly connected to the flood discharge channel 1 and the flow storage component 32, respectively. The diversion plate 4 is conical and located on one side of the guide component 31. A filter screen is provided inside the diversion plate 4.
[0036] In the above embodiment, since a filter screen is installed inside the diversion plate 4, the silt can be filtered through the filter screen. The filtered silt enters the interior of the guide component 31 under the action of the flood. Under the action of the guide component 31, the flood containing silt can be introduced into the interior of the storage component 32 and the silt can be separated.
[0037] Specifically, two sets of fixing brackets 312 are provided inside the pipe 311 of the guide assembly 31, and the helical rod 314 is rotatably installed between the two sets of fixing brackets 312. At the same time, a turbine blade 313 is installed at one end of the helical rod 314. Therefore, when floodwater enters the pipe 311, the turbine blade 313 can drive the helical rod 314 to rotate. The rotation of the helical rod 314 can prevent silt from accumulating inside the pipe 311.
[0038] Furthermore, since the other end of the pipe 311 is connected to the first reservoir 321, and filter plates 322 are fixedly installed inside both the first reservoir 321 and the second reservoir 324, floodwater carrying silt can enter the interior of the first reservoir 321 and the second reservoir 324 for treatment.
[0039] Multiple parallel connecting pipes 323 are provided between the first reservoir 321 and the second reservoir 324. One end of the connecting pipe 323 is located on the upper part of the filter plate 322 inside the first reservoir 321, while the other end of the connecting pipe 323 is located on the lower part of the filter plate 322 inside the second reservoir 324, so that the flood can be treated twice.
[0040] It should be noted that since a baffle 5 is installed inside the flood discharge channel 1, and one end of the return water channel 325 is located at the top of the baffle 5, the baffle 5 can effectively prevent floodwater from flowing back into the interior of the return water channel 325.
[0041] See attached document Figure 1 , Figure 2 , Figure 4 and Figure 5 In this embodiment, the water-blocking mechanism 2 includes a gantry 21, an opening and closing mechanism 23 is fixedly installed on the top of the gantry 21, and an installation base 24 is fixedly installed on the bottom of the opening and closing mechanism 23.
[0042] In the above embodiment, the gate plate 22 is slidably installed inside the gantry 21, and the gate plate 22 can be driven to slide vertically inside the gantry 21 by activating the opening and closing mechanism 23, thereby realizing the automatic opening and closing of the water blocking mechanism 2.
[0043] The opening and closing mechanism 23 includes a motor 231 and a bracket 234. The motor 231 drives the reduction gearbox 232 to rotate the second gear 237. The first gear 235 is rotatably mounted on the bottom of the bracket 234. The first gear 235 is threadedly installed with the screw 236.
[0044] According to the above mechanism, starting the motor 231 can cause the gearbox 232 to drive the first gear 235 to rotate through the second gear 237. Since the first gear 235 is limited by the bracket 234, the screw 236 can move vertically under the action of the thread between the first gear 235 and the screw 236. Since the bottom of the screw 236 is fixedly installed with the mounting base 24 between the gate plate 22, the screw 236 will not rotate under the action of the mounting base 24 and the gate plate 22, and can also drive the mounting base 24 and the gate plate 22 to move vertically synchronously.
[0045] The working principle of this utility model is as follows: When flood discharge is required, simply start the motor 231 to drive the reduction gearbox 232 to rotate, so that the reduction gearbox 232 drives the first gear 235 to rotate through the second gear 237. Since the first gear 235 is threadedly installed with the screw 236, and the bottom of the screw 236 is fixedly installed with the gate plate 22 through the mounting base 24, the screw 236 can drive the gate plate 22 to slide upward inside the gantry 21 through the mounting base 24, thus allowing flood discharge. Since the flood discharge channel 1 is equipped with a diversion plate 4, the filter screen inside the diversion plate 4 blocks the silt, and the silt... The floodwaters then enter the interior of pipe 311, driving turbine blades 313 to rotate screw rod 314. The rotation of guide assembly 31 prevents blockage inside pipe 311. The floodwaters carrying silt enter the interior of first reservoir 321 through pipe 311. The floodwaters undergo primary treatment through filter plate 322 inside first reservoir 321. After treatment, the floodwaters enter the interior of second reservoir 324 through connecting pipe 323 for secondary treatment. Then, they return to the top of baffle 5 through return channel 325, thus entering the interior of flood discharge channel 1 to merge with the floodwaters.
[0046] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
