Description

Technical Field

[0001] This utility model relates to the field of river management technology, specifically to a sediment trapping device for river sedimentation. Background Technology

[0002] In river management, in order to improve river water quality, control siltation, ensure ecological security, or realize resource utilization, interception devices are used to intercept and separate water flow, silt, pollutants, or specific substances in the river. Suspended solids, silt, pollutants, and other particulate matter in the river water are trapped in specific areas, thereby purifying the water quality and reducing siltation.

[0003] Current river interception devices use inclined plates to intercept river channels. Water flows on the inclined plates, and the gravity sedimentation of particles is used to trap silt and suspended particles on the inclined plates. However, in actual interception processes, it has been found that there are large suspended solids in the river flow, which are difficult to effectively trap and settle. At the same time, when the water flows on the inclined plates, some suspended particles are still pushed away by the water flow from above the inclined plates, resulting in poor interception effect.

[0004] In summary, there is a need for a river interception device that can intercept suspended solids and efficiently retain them. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a interception device for river sedimentation, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

The second water distribution plate is fixedly installed inside the interception box, and multiple sets of second water guide plates and second water baffles are distributed in a V-shape on both sides of the second water distribution plate.

[0012] Furthermore, both the first and second water guide plates are inclined, and the distance between the second water guide plate and the second water baffle is less than the distance between the first water guide plate and the first water baffle.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] To address the technical problems in the background section, the following interception device for river sedimentation is provided:

[0025] Combination Figures 1-4 As shown, this utility model provides an interception device for river sedimentation, including an interception box 1. The interception box 1 is divided into an interception chamber and a sedimentation chamber. The interception chamber has a lower outlet 14 communicating with the sedimentation chamber in the middle. One end of the interception chamber is provided with an interception mechanism 1 2 and an interception mechanism 2 3, and the other side of the interception chamber is provided with an interception mechanism 3 5. The end of the interception mechanism 2 3 is provided with a filter assembly. The interception mechanism 3 5 includes an interception plate 51 and flow-blocking blocks 52. The interception plate 51 is inclined, and the flow-blocking blocks 52 are provided on the side of the interception plate 51. The flow-blocking blocks 52 are distributed in a staggered array. It has an inverted triangular structure, with an inlet 11 and an outlet 12 at both ends of the interception chamber, and a debris discharge port 13 at the end of the sedimentation chamber. The inclined interception plate 51 can intercept suspended particles in the water flow on the inclined surface under the action of gravity of suspended matter, and slide down the inclined surface and enter the sedimentation chamber through the lower debris port 14. The array of flow-blocking blocks 52 can disperse and buffer the water flow during the water flow process, reduce the impact force of the water flow, reduce the situation of poor interception effect of suspended matter sedimentation caused by water flow, and thus help improve the interception effect of the interception device on river water.

[0026] In this embodiment, the interception mechanism 2 further includes a water-dividing plate 21, a water-guiding plate 22, and a water-blocking rod 23. The water-dividing plate 21 is fixedly installed inside the interception box 1. The water-guiding plate 22 and the water-blocking rod 23 are evenly distributed on both sides of the water-dividing plate 21. The water-blocking rod 23 and the water-guiding plate 22 are arranged in a V-shape. The V-shaped arrangement of the water-blocking rod 23 and the water-guiding plate 22 can screen the incoming river water to a certain extent when the river water flows through it, and guide the water flow to the filter assembly 4, so as to concentrate and filter larger suspended solids in the river water, which is beneficial to improving the water quality after interception.

[0027] In this embodiment, the interception mechanism 2 3 is further arranged at intervals with the interception mechanism 1 2. The interception mechanism 2 3 includes a water distribution plate 2 31, a water guide plate 2 32, and a water baffle rod 2 33. The water distribution plate 2 31 is fixedly installed inside the interception box 1. Multiple sets of water guide plates 2 32 and water baffle rods 2 33 are distributed in a V-shape on both sides of the water distribution plate 2 31. The water guide plates 2 32 and water baffle rods 2 33 can screen and guide the river water again after the interception mechanism 1 2 screens and guides the river water, further removing larger suspended solids or debris in the river water flow.

[0028] In this embodiment, both the first water guide plate 22 and the second water guide plate 32 are inclined. The distance between the second water guide plate 32 and the second water baffle 33 is smaller than the distance between the first water guide plate 22 and the first water baffle 23. The different distances between the second water guide plate 32 and the second water baffle 33, and between the first water guide plate 22 and the first water baffle 23, can perform double screening of the river water flow and fully remove larger suspended solids or debris from the river water flow.

[0029] In this embodiment, the filter assembly 4 further includes a filter box 41 and a filter screen 42. A collection chamber is formed in the middle of the filter box 41, and a filter screen 42 is provided on the side of the collection chamber. The filter screen 42 is connected to the interception chamber. The filter screen 42 can filter the river water entering the collection chamber and send the filtered river water back to the interception chamber.

[0030] As an improvement to the above solution, the top of the interception box 1 is provided with a box cover 6, and a cleaning door 61 is opened in the middle of the box cover 6. The cleaning door 61 is set in correspondence with the filter assembly 4. The setting of the cleaning door 61 makes it convenient for staff to clean and discharge the suspended solids and debris in the collection chamber after they are collected in the collection chamber.

[0031] Working principle and usage process of this utility model:

[0032] When using:

[0033] First, the river water is connected to the inlet 11 of the interception device. When the river water enters the interception chamber inside the interception box 1, the V-shaped water guide plate 22 and the water baffle 23 in the interception mechanism 2 will screen and guide the river water, directing a portion of the river water and suspended solids and debris into the filter box 41 of the filter assembly 4. Then, the V-shaped water guide plate 32 and the water baffle 23 in the interception mechanism 3 will further screen and guide the river water after the interception mechanism 2 to the filter box 41. After being filtered by the filter screen 42, the river water will flow back into the interception chamber. In this way, larger suspended solids and debris in the river water will be concentrated in the filter box 41, making it convenient for staff to clean.

[0034] During the interception process:

[0035] When the river water passes through the interception mechanism 5, it flows above the inclined interception plate 51. Under the action of gravity, the suspended matter in the river water will be intercepted on the inclined surface and slide down the inclined surface, entering the sedimentation chamber through the lower impurity outlet 14. During this process, the flow-blocking blocks 52 arranged in an array above the inclined surface will disperse and buffer the water flow, reduce the impact force of the water flow, and reduce the situation where the suspended matter sedimentation interception effect is poor due to the water flow. This is conducive to improving the interception effect of the interception device on the river water.
