Description

Technical Field

[0001] This utility model belongs to the technical field of flood control and drainage equipment, specifically relating to an ecological flood control and drainage filtration device. Background Technology

[0002] Floodwaters often carry suspended solids such as silt and garbage, which can lead to sedimentation if directly entering pipes or pumping stations. Ecological flood control and drainage filtration devices combine ecological engineering technology with traditional flood control facilities to filter pollutants from floodwaters through natural purification. These devices typically incorporate multi-layered filtration mechanisms, such as vegetation layers and pebble bed layers, to remove pollutants from floodwaters step by step.

[0003] In the use of existing ecological flood control and drainage filtration devices, although the filter screens in the multi-layer filtration mechanism can block suspended matter such as aquatic plants from passing through, these suspended matter are large in size and easily clog the mesh of the filter screen, making it difficult for water to pass through the filter screen and resulting in insufficient filtration efficiency. Although some filtration devices install crushing rollers at the water inlet to reduce the clogging of suspended matter, the crushing rollers can easily reduce the flow rate of water at the water inlet, making filtration inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide an ecological flood control and drainage filtration device that can move suspended solids in the water at the inlet to an inclined plate via an intercepting rake, where the pulverizing component pulverizes the suspended solids, and then the conveying component moves the pulverized suspended solids to the outside of the pool, reducing the clogging caused by suspended solids. In addition, the intercepting rake has little obstruction to the water flow, improving the convenience of filtration.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] An ecological flood control and drainage filtration device includes a pool body with a water inlet fixedly connected to the pool body, and further includes:

[0007] A pre-filtration mechanism is provided in the pool body. The pre-filtration mechanism includes a housing fixedly connected to the inner wall of the pool body. A pulverizing component is rotatably installed inside the housing body. An inclined plate is provided at one end of the pulverizing component near the water inlet. An intercepting rake is rotatably installed on the inclined plate. The intercepting rake is located at the end of the water inlet on the side near the water inlet. A conveying component is provided below the pulverizing component. The end of the conveying component away from the pulverizing component extends to the outside of the pool body.

[0008] The intercepting rake rotates and moves the suspended matter in the water at the inlet to the inclined plate. The crushing component crushes the suspended matter and then the crushed suspended matter is transported to the outside of the pool by the conveying component.

[0009] The crushing assembly includes a first crushing roller and a second crushing roller rotatably connected inside the housing. A first motor is provided at one end of the first crushing roller, and the first crushing roller is fixedly connected to the output end of the first motor. The first motor is fixedly connected to the housing. A first gear is fixedly connected to the other end of the first crushing roller. A second gear is fixedly connected to the end of the second crushing roller near the first gear. The first gear and the second gear mesh with each other.

[0010] The intercepting rake includes a shaft rotatably mounted on an inclined plate, on which a plurality of rake teeth are fixedly connected. The inclined plate has a plurality of grooves at one end near the intercepting rake, and the grooves are aligned with the rake teeth.

[0011] The shaft is rotatably connected to the inclined plate, and a second motor is provided at one end of the shaft. The shaft is fixedly connected to the output end of the second motor, and the second motor is fixedly connected to the inclined plate.

[0012] The conveying assembly includes a first rotating roller and a second rotating roller rotatably connected to the housing. A conveyor belt is connected to the first rotating roller and the second rotating roller. A third motor is provided at the end of the first rotating roller. The first rotating roller is fixedly connected to the output end of the third motor. The third motor is fixedly connected to the housing.

[0013] Several baffles are provided on the outer side of the conveyor belt, and the baffles are fixedly connected to the conveyor belt.

[0014] A drain hole is provided on the inner wall at the lower end of the housing, and the drain hole is close to the lower end of the conveying assembly.

[0015] The technical effects achieved by this utility model are as follows:

[0016] The intercepting rake in this invention moves suspended matter in the water at the inlet to the inclined plate, where the pulverizing component pulverizes the suspended matter. Then, the pulverized suspended matter is moved to the outside of the pool by the conveying component. Compared with the prior art, this reduces the situation where suspended matter such as aquatic plants clogs the multi-layer filtration mechanism, making it difficult for water to pass through the filter screen, and improves the filtration efficiency.

[0017] The intercepting rake of this utility model is set at the end of the water inlet. Compared with the prior art where the crushing roller is set at the water inlet, the intercepting rake obstructs the water flow less, reduces the situation where the crushing roller is installed at the water inlet and reduces the water flow velocity, and improves the convenience of filtration.

[0024] 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 implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figures 1 to 4 As shown, an ecological flood control and drainage filtration device includes a pool body 10, with an inlet 11 fixedly connected to the pool body 10. It also includes a pre-filtration mechanism 20, which is disposed in the pool body 10. The pre-filtration mechanism 20 includes a housing 21 fixedly connected to the inner wall of the pool body 10. A crushing component 22 is rotatably installed inside the housing 21. An inclined plate 23 is provided at one end of the crushing component 22 near the inlet 11. An intercepting rake 24 is rotatably installed on the inclined plate 23. The intercepting rake 24 is located at the end of the inlet 11 near the side of the inlet 11. A conveying component 25 is provided below the crushing component 22. The end of the conveying component 25 away from the crushing component 22 extends to the outside of the pool body 10.

[0026] It should be noted that the interior of the pool body 10 is equipped with a multi-layer filtration mechanism (not shown in the figure). The multi-layer filtration mechanism is located below the pre-filtration mechanism 20. The multi-layer filtration mechanism is existing technology and includes a biofiltration layer for biodegradation and a chemical adsorption layer for removing heavy metal ions. It will not be described in detail here. The inclined plate 23 is inclined. The height of the end of the inclined plate 23 near the crushing component 22 is lower than the height of the end of the inclined plate 23 near the intercepting rake 24. The conveying component 25 is inclined. The lower end of the conveying component 25 is located below the crushing component 22, and the higher end of the conveying component 25 extends to the outside of the pool body 10.

[0027] In this embodiment, as water flows into the pool 10 through the inlet 11, the end of the intercepting rake 24 at the inlet 11 rotates to intercept suspended matter such as weeds in the water and moves these suspended matter to the inclined plate 23. Under the action of its own gravity, the suspended matter moves along the inclined plate 23 to the crushing component 22. After the crushing component 22 works, it crushes the suspended matter. The crushed suspended matter falls down to the conveying component 25. After the conveying component 25 works, it moves the crushed suspended matter to the outside of the pool 10, thereby crushing the suspended matter in the water and discharging it to the outside of the pool 10. Compared with the prior art, this reduces the situation where suspended matter such as weeds clogs the multi-layer filtration mechanism, making it difficult for water to pass through the filter screen, thus improving the filtration efficiency. Moreover, compared with the crushing roller, the intercepting rake 24 obstructs the water flow less, reducing the situation where the crushing roller is installed at the inlet 11 and reduces the water flow velocity, thus improving the convenience of filtration.

[0028] like Figure 2 and Figure 4 As shown, the crushing assembly 22 includes a first crushing roller 31 and a second crushing roller 32 rotatably connected inside the housing 21. A first motor 33 is provided at one end of the first crushing roller 31, and the first crushing roller 31 is fixedly connected to the output end of the first motor 33. The first motor 33 is fixedly connected to the housing 21. A first gear 34 is fixedly connected to the other end of the first crushing roller 31. A second gear 35 is fixedly connected to the end of the second crushing roller 32 near the first gear 34. The first gear 34 and the second gear 35 mesh with each other.

[0029] It should be noted that the first crushing roller 31 and the second crushing roller 32 are both existing technologies. The surfaces of the first crushing roller 31 and the second crushing roller 32 are provided with a number of crushing teeth for crushing suspended matter, which will not be described in detail here.

[0030] In this embodiment, after the first motor 33 is working, its output end drives the first crushing roller 31 to rotate. The first crushing roller 31 drives the second crushing roller 32 to rotate in the opposite direction through the first gear 34 and the second gear 35. When the suspended matter passes between the first crushing roller 31 and the second crushing roller 32, the first crushing roller 31 and the second crushing roller 32 tear the suspended matter, thereby facilitating the crushing of the suspended matter.

[0031] like Figure 3 and Figure 4 As shown, the intercepting rake 24 includes a shaft 241 rotatably mounted on an inclined plate 23. Several rake teeth 242 are fixedly connected to the shaft 241. Several grooves 231 are provided at one end of the inclined plate 23 near the intercepting rake 24. The grooves 231 are aligned with the rake teeth 242.

[0032] It should be noted that the rake teeth 242 are columnar rods, and several rake teeth 242 are staggered along the axial direction of the shaft 241.

[0033] In this embodiment, the shaft 241 rotates, causing the rake teeth 242 to rotate, which in turn causes the rake teeth 242 to move suspended objects such as aquatic plants onto the inclined plate 23. After the suspended objects slide down the inclined plate 23 to the crushing component 22, the rake teeth 242 continue to rotate and pass through the groove 231, thereby facilitating the continued interception of suspended objects.

[0034] like Figure 2 and Figure 3 As shown, the shaft 241 is rotatably connected to the inclined plate 23. A second motor 41 is provided at one end of the shaft 241. The shaft 241 is fixedly connected to the output end of the second motor 41. The second motor 41 is fixedly connected to the inclined plate 23.

[0035] In this embodiment, after the second motor 41 is working, the output end drives the shaft 241 to rotate, which facilitates the rotation of the rake teeth 242 and moves the suspended object onto the inclined plate 23.

[0036] like Figure 4 As shown, the conveying assembly 25 includes a first rotating roller 251 and a second rotating roller 252 rotatably connected to the housing 21. A conveyor belt 253 is connected to the first rotating roller 251 and the second rotating roller 252. A third motor 254 is provided at the end of the first rotating roller 251. The first rotating roller 251 is fixedly connected to the output end of the third motor 254. The third motor 254 is fixedly connected to the housing 21.

[0037] It should be noted that the conveyor belt 253 is wound around the outside of the first rotating roller 251 and the second rotating roller 252.

[0038] In this embodiment, after the third motor 254 is working, its output end drives the first rotating roller 251 to rotate. The first rotating roller 251 drives the conveyor belt 253 and the second rotating roller 252 to rotate, so that the conveyor belt 253 carries the suspended matter falling from the crushing component 22 to the outside of the pool body 10, reducing the situation where the crushed suspended matter falls into the water, and facilitating the subsequent collection and treatment of the suspended matter that has moved to the outside of the pool body 10.

[0039] like Figure 4 As shown, several baffles 42 are provided on the outer side of the conveyor belt 253, and the baffles 42 are fixedly connected to the conveyor belt 253.

[0040] In this embodiment, the baffle 42 prevents the suspended matter on the conveyor belt 253 from moving downward, reducing the situation where insufficient friction between the conveyor belt 253 and the suspended matter makes it difficult to move the suspended matter to the outside of the pool body 10.

[0041] like Figure 2 and Figure 3 As shown, a drain hole 43 is provided on the inner wall at the lower end of the housing 21, and the drain hole 43 is close to the lower end of the conveying assembly 25.

[0042] It should be noted that the drain hole 43 is a through hole, and the inner and outer sides of the shell 21 are connected through the drain hole 43. The diameter of the drain hole 43 is smaller than the diameter of the suspended matter after it is broken up.

[0043] In this embodiment, after the suspended matter leaves the water, it is easy for a certain amount of water to adhere to it. After the crushing component 22 crushes the suspended matter, the water falls onto the conveyor belt 253. Under the action of its own gravity, the water moves along the conveyor belt 253 towards the lower end of the housing 21. The drain hole 43 facilitates the discharge of the water located at the lower end of the housing 21 to the outside of the housing 21, reducing the situation where water accumulates at the lower end of the housing 21 and affects the conveying component 25 in conveying the crushed suspended matter.

[0044] The working principle of this utility model is as follows: When water flows through the end of the inlet 11, the intercepting rake 24 prevents suspended matter such as aquatic plants in the water from continuing to move into the pool body 10. After the intercepting rake 24 rotates, it drives these suspended matter to the inclined plate 23. The suspended matter moves along the inclined plate 23 to the crushing component 22 for crushing. The crushed suspended matter falls onto the conveying component 25 and is moved to the outside of the pool body 10 by the conveying component 25, reducing the clogging of suspended matter. Compared with the existing technology that sets the crushing roller at the end of the inlet 11, the intercepting rake 24 has less obstruction to the water flow, reduces the impact on the flow rate of the water, and improves the convenience of filtration.

[0045] 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 principles 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.
