Description
Technical Field
[0001] This utility model relates to the technical field of rainwater collection and treatment equipment, and more specifically, to an anti-siltation filtration device for a rainwater collection sedimentation observation well. Background Technology
[0002] With the acceleration of urbanization, the rational use of water resources and environmental protection are becoming increasingly important. As a key part of the rainwater harvesting system, the rainwater collection and sedimentation observation well is used to collect and settle rainwater, and to facilitate staff to observe water quality and water level. However, rainwater carries a large amount of silt and other impurities. If the sediment in the observation well is not cleaned in time, it can easily cause siltation at the bottom of the observation well, affecting the rainwater collection efficiency and the normal use of the observation well.
[0003] Traditional anti-sludge filtration devices typically require workers to enter the well for maintenance. However, the confined space underground increases the difficulty of operation, requiring a significant amount of time and effort, resulting in low cleaning efficiency.
[0004] Existing reference CN202321289152.9 describes a sewage pipe dredging device. This device, through an internal drive mechanism and lifting screw, can lower the entire dredging mechanism into the pipe, during which the mechanism continuously agitates the sludge inside. However, this method requires opening the pipe or manhole cover and extending into the pipe to perform the agitation.
[0005] Therefore, we have made improvements to this by proposing an anti-siltation filtration device for rainwater collection and sedimentation observation wells. Utility Model Content
[0006] The purpose of this utility model is to address the fact that traditional anti-sludge filtration devices typically require workers to enter the well for maintenance. However, the limited space underground increases the difficulty of operation for workers, requiring a lot of time and effort, resulting in low cleaning efficiency.
[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:
[0008] A silt-prevention filtration device for a rainwater collection and sedimentation observation well is provided to improve the aforementioned problems.
[0009] The application is as follows:
[0010] It includes: an observation well body; a conveying component for discharging sludge is provided on the right side of the observation well body, a limiting frame is fixedly connected to the inner surface of the observation well body, and a filter element is slidably connected to the upper surface of the limiting frame.
[0011] The above technical solution utilizes the filtering components to block foreign objects on the upper surfaces of filter screen one, filter screen two, and the manhole cover. After unscrewing the bolts from the mounting holes, the manhole cover, filter screen two, and filter screen one can be disassembled for cleaning. The motor in the conveying component drives the screw rod to rotate, which transports the sludge inside the collection box through conveying pipe one and conveying pipe two. This greatly reduces the difficulty of operation for workers and improves the safety and efficiency of the operation.
[0012] As a preferred embodiment of the anti-siltation filtration device for the rainwater collection and sedimentation observation well provided by this utility model, a sedimentation tank is fixedly connected to the lower surface of the observation well body, the lower part of the sedimentation tank 2 is tapered downward and fixedly connected to a collection box, the collection box is bent; a lower mounting plate is fixedly connected to the inner bottom surface of the collection box, and the observation well body, sedimentation tank and collection box are all set inside the ground.
[0013] To achieve the above technical solution, since the inner surfaces of the collection box and the lower mounting plate are both inclined, the sludge moves sequentially through the observation well body and the collection box into the interior of the lower mounting plate under its own gravity.
[0014] As a preferred embodiment of the anti-siltation filtration device for the rainwater collection sedimentation observation well provided by this utility model, the conveying component includes a conveying pipe, which is fixedly connected to the collection box. The upper surface of the conveying pipe extends above the ground and is fixedly connected to a motor. The output end of the motor extends into the interior of the conveying pipe and is fixedly connected to a screw rod, which is coaxially connected to the screw rod via a coupling. The bottom end of the screw rod is rotatably connected to the lower mounting plate. The top end of the screw rod passes through the upper mounting plate and is rotatably connected to the upper mounting plate.
[0015] One end of the screw rod is rotatably connected to the lower mounting plate, and a second conveying pipe is fixedly connected to one side of the outer surface of the first conveying pipe. The second conveying pipe is connected to the first conveying pipe.
[0016] To achieve the above technical solution, the motor starts working and drives the screw rod to rotate. The rotation of the screw rod causes the sludge inside the collection box to be discharged sequentially through conveying pipe one and conveying pipe two.
[0017] As a preferred embodiment of the anti-siltation filtration device for the rainwater collection sedimentation observation well provided by this utility model, the filter element includes a mounting frame, which is slidably disposed on the upper surface of the limiting frame and has a latch at the bottom; the latch is adapted to the limiting frame; a stepped surface is provided on the inner side of the mounting frame, and a filter screen is slidably installed at the bottom of the stepped surface.
[0018] The inner side of the mounting bracket is slidably mounted on the upper side of the filter screen.
[0019] The second filter screen is slidably installed on the inner side of the mounting bracket, which is located above the first connecting bracket.
[0020] As a preferred embodiment of the anti-siltation filtration device for the rainwater collection and sedimentation observation well provided by this utility model, a connecting frame two is slidably connected to the inner surface of the observation well body above the filter screen two, and a well cover is fixedly connected to the upper surface of the connecting frame two; multiple sets of filter holes are opened on the upper surface of the well cover; the connecting frame two slides against the inner wall of the observation well body, and the bottom of the connecting frame two and the mounting frame are pressed together.
[0021] As a preferred embodiment of the anti-siltation filtration device for the rainwater collection and sedimentation observation well provided by this utility model, four mounting holes are provided on the upper surface of both the well cover and the observation well body, and bolts are threaded onto the inner surface of the mounting holes.
[0022] To achieve the above technical solution, after unscrewing the four bolts from the four mounting holes, remove the manhole cover and connecting bracket 2 from the observation well body. Then, remove filter screen 2, connecting bracket 1, and filter screen 1 from the observation well body in sequence to clean filter screen 1 and filter screen 2. After cleaning, slide filter screen 1, connecting bracket 1, filter screen 2, connecting bracket 2, and manhole cover into the observation well body in sequence, and then rotate the bolts back into the mounting holes. The upper and lower sides of connecting bracket 1 are respectively attached to filter screen 2 and filter screen 1, and the lower surface of connecting bracket 2 is attached to filter screen 2, thereby fixing filter screen 1 and filter screen 2.
[0023] In a preferred embodiment of the anti-siltation filtration device for the rainwater collection and sedimentation observation well provided by this utility model, a guide plate is fixedly connected to the inner surface of the observation well body, and several notches are opened on the side of the guide plate. The guide plate is shaped with a high center and low sides; the guide plate is installed between the limiting frame and the sedimentation tank.
[0024] To achieve the above technical solution, after water flows into the interior of the observation well body through filter screen two and filter screen one, it comes into contact with the upper surface of the guide plate, then flows in all directions and flows downward along the inner wall of the observation well body through the gap. This greatly reduces the impact force of the water, effectively avoids the sludge inside the sedimentation tank being directly impacted by the water, and promotes the sedimentation of the sludge.
[0025] Compared with the prior art, the beneficial effects of this utility model are as follows:

The filter element blocks foreign objects on the upper surfaces of filter screen one, filter screen two, and the well cover. After unscrewing the bolts from the mounting holes, the well cover, filter screen two, and filter screen one can be disassembled for cleaning. The motor in the conveying component drives the screw rod to rotate, thus conveying the sludge inside the collection box through conveying pipe one and conveying pipe two. This greatly reduces the operational difficulty for workers and improves the safety and cleaning efficiency of the operation. Attached Figure Description

Detailed Implementation
[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.
[0035] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0036] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0037] Example 1
[0038] Please refer to Figure 1-5 This invention provides an embodiment of a rainwater collection and sedimentation observation well, comprising: an observation well body 1; and a rainwater collection and sedimentation observation well anti-siltation filtration device. Figure 1 As shown, a conveying device for discharging sludge is provided on the right side of the observation well body 1. A limit frame 4 is fixedly connected to the inner surface of the observation well body 1, and a filter is slidably connected to the upper surface of the limit frame 4.
[0039] A sedimentation tank 2 is fixedly connected to the lower surface of the observation well body 1. The lower part of the sedimentation tank 2 is tapered downward and fixedly connected to a collection box 21. A lower mounting plate 22 is fixedly connected to the inner bottom surface of the collection box 21. The observation well body 1, sedimentation tank 2 and collection box 21 are all located inside the ground.
[0040] Combination Figure 2 As shown, the conveying component includes a conveying pipe 3, which is fixedly connected to the collection box 21. The upper surface of the conveying pipe 3 extends above the ground and is fixedly connected to a motor 31. A protective cover is optionally installed on the motor 31, which can provide rain and sun protection as well as anti-theft protection. The output end of the motor 31 extends into the interior of the conveying pipe 3 and is coaxially connected to the screw rod 32 via a coupling.
[0041] The bottom end of the spiral rod 32 is rotatably connected to the lower mounting plate 22; the top of the spiral rod 32 passes through the upper mounting plate and is rotatably connected to the upper mounting plate.
[0042] A second conveying pipe 33 is fixedly connected to one side of the outer surface of the first conveying pipe 3, and the second conveying pipe 33 is connected to the first conveying pipe 3.
[0043] like Figure 2 As shown, because the inner surfaces of the collection box 21 and the lower mounting plate 22 are both inclined, the sludge moves sequentially through the observation well body 1 and the collection box 21 into the lower mounting plate 22 under its own gravity. The motor 31 starts to work and drives the screw rod 32 to rotate. The rotation of the screw rod 32 causes the sludge inside the collection box 21 to be discharged sequentially through the first conveying pipe 3 and the second conveying pipe 33.
[0044] Please refer to Figure 4 and Figure 5 The filter element includes a mounting bracket 41, which is slidably mounted on the upper surface of the limiting bracket 4. A filter screen 42 is slidably connected to the inner bottom surface of the mounting bracket 41. A connecting bracket 43 is slidably connected to the inner surface of the mounting bracket 41 above the filter screen 42. A filter screen 44 is slidably connected to the inner surface of the mounting bracket 41 above the connecting bracket 43. A connecting bracket 45 is slidably connected to the inner surface of the observation well body 1 above the filter screen 44. A well cover 46 is fixedly connected to the upper surface of the connecting bracket 45. Both the well cover 46 and the upper surface of the observation well body 1 have four mounting holes 47, and bolts 48 are threaded onto the inner surface of the mounting holes 47. The upper surface of the well cover 46 has multiple sets of water filtering holes. The connecting bracket 45 slidably fits against the inner wall of the observation well body 1, and its bottom together presses against the filter screen 44 and the mounting bracket 41.
[0045] A guide plate 5 is fixedly connected to the inner surface of the observation well body 1. Several notches 51 are opened on the side of the guide plate 5. The height of the middle part of the guide plate is higher than the height of the four sides. When cleaning is required, after unscrewing the four bolts 48 from the four mounting holes 47, the well cover 46 and the second connecting bracket 45 are removed from the inside of the observation well body 1. Then, the second filter screen 44, the first connecting bracket 43, and the first filter screen 42 are removed from the inside of the observation well body 1 in sequence to clean the first filter screen 42 and the second filter screen 44. After cleaning, the first filter screen 42, the first connecting bracket 43, the second filter screen 44, the second connecting bracket 45, and the well cover 46 are slid into the inside of the observation well body 1 in sequence, and the bolts 48 are turned back to the mounting holes. The interior of hole 47 is used for mounting. The upper and lower sides of connecting bracket 43 are respectively attached to filter screen 44 and filter screen 42. The lower surface of connecting bracket 45 is attached to filter screen 44, thereby fixing filter screen 42 and filter screen 44. After water flows into the interior of the observation well body 1 through filter screen 44 and filter screen 42, it contacts the upper surface of the guide plate 5, and then flows to all sides and flows down along the inner wall of the observation well body 1 through the notch 51. This greatly reduces the impact force of the water and effectively avoids the sludge inside the sedimentation tank 2 from being directly impacted by the water, thus promoting the sedimentation of the sludge.
[0046] Specifically, when cleaning is required, after unscrewing the four bolts 48 from the four mounting holes 47, remove the manhole cover 46 and connecting bracket 2 45 from the inside of the observation well body 1. Then, remove the filter screen 2 44, connecting bracket 1 43 and filter screen 1 42 from the inside of the observation well body 1 in sequence to clean the filter screen 1 42 and filter screen 2 44.
[0047] After cleaning, slide the filter screen 42, connecting bracket 43, filter screen 44, connecting bracket 45, and well cover 46 into the observation well body 1 in sequence, and then rotate the bolt 48 back into the mounting hole 47. The upper and lower sides of connecting bracket 43 are respectively attached to filter screen 44 and filter screen 42, and the lower surface of connecting bracket 45 is attached to filter screen 44, thus fixing filter screen 42 and filter screen 44. Water flows into the observation well body 1 through filter screen 44 and filter screen 42, and then onto the upper surface of the guide plate 5. The water makes contact with the surface and then flows outwards and downwards along the inner wall of the observation well body 1 through the gap 51, greatly reducing the impact force of the water and effectively preventing the sludge inside the sedimentation tank 2 from being directly impacted by the water, thus promoting the sedimentation of the sludge. Because the inner surfaces of the collection box 21 and the lower mounting plate 22 are both inclined, the sludge moves into the interior of the lower mounting plate 22 in sequence through the observation well body 1 and the collection box 21 under its own gravity. The motor 31 starts to work and drives the screw rod 32 to rotate. Through the rotation of the screw rod 32, the sludge inside the collection box 21 is discharged in sequence through the first conveying pipe 3 and the second conveying pipe 33.
[0048] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
