Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a floating debris interception mechanism for water conservancy slope protection. Background Technology

[0002] As a vital component of urban drainage, flood control, and ecosystems, waterways play a crucial role in ensuring urban safety and environmental sanitation through water management. With rapid urbanization, waterway pollution has become increasingly prominent, particularly the removal of floating debris, which has become a key focus and challenge in waterway maintenance. To improve water quality and aesthetic appeal, more efficient methods for cleaning and intercepting pollutants are urgently needed.

[0003] Currently, river pollution control typically involves installing fixed interception nets along the riverbanks or relying on manual, periodic dredging and cleaning of floating debris. Manual dredging is inefficient, labor-intensive, and poses safety risks. Fixed interception nets, on the other hand, have no adjustable tilt angle, making them susceptible to ineffective interception when water flow changes or the distribution of floating debris is uneven, leading to increased pollution downstream. Furthermore, fixed structures are limited by terrain and cannot adapt to changes in water level or river width, increasing maintenance difficulty, reducing cleaning efficiency, and hindering intelligent and refined water management. Utility Model Content

[0004] The technical problem this invention aims to solve is that fixed interception nets, due to their non-adjustable tilt angle, are difficult to adapt to changes in water flow and terrain differences, easily miss floating objects, and are difficult to maintain.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a floating debris interception mechanism for water conservancy slope protection, including a base plate, a receiving core fastened to the top of the base plate, interception filter plates fastened to both sides of the receiving core, the interception filter plates having a plurality of filter holes, a first limiting plate fixedly connected to both sides of the base plate, the first limiting plate being rotatably connected to a second limiting plate via a rotating shaft, the first limiting plate and the second limiting plate each having a plurality of insertion holes, an insertion block being inserted between the first limiting plate and the second limiting plate, and an installation block being fixedly connected to the top and bottom of the second limiting plate, the installation block having threaded installation bolts.

[0006] As a further improvement of this utility model, the plurality of said insertion holes are evenly arranged along the axis of the first limiting plate and the second limiting plate, respectively.

[0007] As a further improvement of this utility model, the plug-in block is configured as a horizontally placed C-shaped rod structure, with both ends passing through the plug holes of the first limiting plate and the second limiting plate, respectively.

[0008] As a further improvement of this utility model, the receiving core is configured as a T-shaped plate structure, and a groove for inserting the receiving core is provided at the top of the substrate. First bolts are respectively provided on both sides of the receiving core, and the first bolts are threadedly connected to the groove.

[0009] As a further improvement of this utility model, a plurality of second bolts are laterally fastened to one side of the receiving core, and the second bolts are respectively fastened to the intercepting filter plate.

[0010] As a further improvement of this utility model, a partition plate is provided on one side of the first limiting plate and the second limiting plate, and a plug-in post is fixedly provided on the inner side of the partition plate. The partition plate is fastened to the substrate through the plug-in post.

[0011] The beneficial effects of this utility model are as follows: 1. By introducing an adjustable-angle interception structure into the interception device, this utility model overcomes the problem of blind spots caused by the single angle of traditional fixed debris nets, which cannot cope with complex water flow environments. The tilt angle of the interception filter plate can be preset and adjusted at multiple angles before installation to adapt to different river flow directions, water levels, and garbage distribution, effectively improving the interception coverage and guiding distribution capacity of floating objects, and preventing garbage from escaping downstream.

[0012] 2. The device features a modular structure, employing a separate combination of a base plate, a receiving core, and intercepting filter plates. Combined with a first limiting plate, a second limiting plate, and a connecting block, it forms a three-dimensional limiting and angle-adjusting mechanism. This not only enables precise adjustment and reliable locking of the filter plate angle but also enhances the flexibility and convenience of subsequent maintenance and cleaning. The accompanying baffle structure effectively prevents contaminants from entering moving parts, improving the overall durability and adaptability of the machine. This design is particularly suitable for rivers with varying flow velocities, different water surface widths, or complex terrain, providing a more efficient and low-maintenance floating debris management solution for water conservancy systems.

It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.

[0020] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0021] This utility model provides a floating debris interception mechanism for hydraulic slope protection, including a base plate 1;

[0022] As attached Figure 1-4 As shown, a receiving core 2 is fastened to the top of the substrate 1. Interception filter plates 3 are fastened to both sides of the receiving core 2, each with several filter holes. First limiting discs 4 are fixedly connected to both sides of the substrate 1. Second limiting discs 5 are rotatably connected to the first limiting discs 4 via a rotating shaft. Both the first and second limiting discs 4 and 5 have multiple insertion holes, evenly arranged along their axes. After rotation, these holes can be aligned with the coaxial insertion holes, facilitating the subsequent insertion and positioning of the insertion block 6. An insertion block 6 is inserted between the first and second limiting discs 4 and 5. Mounting blocks are fixedly connected to the top and bottom of the second limiting disc 5, and threaded mounting bolts pass through the mounting blocks. A partition plate 9 is provided on one side of the first limiting plate 4 and the second limiting plate 5, and a plug-in post is fixedly provided on the inner side of the partition plate 9. The partition plate 9 is fastened to the base plate 1 through the plug-in post to prevent dirt from getting stuck at the connection between the first limiting plate 4 and the second limiting plate 5.

[0023] As attached Figure 2-4As shown, the plug-in block 6 is configured as a horizontal C-shaped rod structure, with both ends passing through the insertion holes of the first limiting disk 4 and the second limiting disk 5 respectively; this facilitates the insertion and limiting of the first limiting disk 4 and the second limiting disk 5, thereby ensuring the angle adjustment effect of the substrate 1, the receiving core 2 and the intercepting filter plate 3.

[0024] As attached Figure 2-4 As shown, the receiving core 2 is configured as a T-shaped plate structure, and the top of the base plate 1 has a groove for inserting the receiving core 2. First bolts 7 are threaded through both sides of the receiving core 2 and connected to the groove. The first bolts 7 are used to reinforce the structural connection between the receiving core 2 and the base plate 1. When it is necessary to clean the intercepting filter plate 3 on the receiving core 2, it can be disassembled and separated through the receiving core 2, the groove, and the first bolts 7. Multiple second bolts 8 are horizontally fastened to one side of the receiving core 2, and the second bolts 8 are respectively fastened to the intercepting filter plate 3; these are used to reinforce the connection between the intercepting filter plate 3 and the receiving core 2.

[0025] Working Principle: In practical implementation, this floating debris interception mechanism uses a base plate 1 as a basic installation platform. The receiving core 2 is inserted into a groove at the top of the base plate 1, and its structure is fixed using a first bolt 7. Multiple interception filter plates 3 are then installed on both sides of the receiving core 2 using second bolts 8. These filter plates have filter holes to filter out floating debris while allowing clean water to pass through. The angle of the interception filter plates 3 can be preset and adjusted during installation. The adjustment method is as follows: by rotating the first limiting plate 4 and the second limiting plate 5, aligning them with the insertion holes at the desired angle, and then inserting the insertion block 6 for limiting and fixing, thereby achieving multi-angle graded locking.

[0026] When the river water level is high (e.g., water depth exceeds 1.5 meters) and the water flow is gentle (flow velocity less than 0.3 m / s), the intercepting filter plate 3 can be set at a smaller angle (10°–15° is recommended), making it approximately vertically arranged. This expands the interception projection area in contact with the water surface, improving the frontal coverage and interception capability of floating debris. Actual measurement data shows that in this state, the filter plate can achieve an average coverage rate of over 85% for surface debris, making it particularly suitable for the efficient collection of lightweight floating debris such as floating leaves, foam, and white pollution that are evenly distributed on the water surface.

[0027] If the water level is low (e.g., less than 0.8 meters deep), the current is rapid (0.8–1.2 m / s), or there is an asymmetrical distribution of floating debris concentrated on one side of the river channel, the angle of the intercepting filter plate 3 can be adjusted to 25°–35° to form an inclined guiding surface. This allows the filter plate to more effectively "face" the direction of the water flow, guiding the floating debris along the intercepting surface to the base of the filter plate, thus enhancing the interception and concentration capacity in the designated area. In this state, the interception and concentration rate of floating debris in the target area can be increased to over 90%, greatly reducing the risk of debris leakage and discharge.

[0028] Furthermore, in areas with severe seasonal water level fluctuations (fluctuations exceeding 0.5 meters) or significant gradients (≥5°) in the river channel, the device can operate stably without frequent adjustments by pre-setting a suitable tilt angle. This reduces the frequency of manual inspections and maintenance, improves system stability and on-site response efficiency, and is suitable for small and medium-sized rivers and urban drainage ditches with unstable water levels and limited management resources. To enhance structural durability and operational safety, a sealing plate 9 is added to the outside of the first limiting plate 4 and the second limiting plate 5. It is securely connected to the base plate 1 via a plug-in post, effectively preventing debris such as branches and plastic bags from getting stuck in the rotating shaft or limiting structure, thus ensuring the long-term smooth operation of the angle adjustment mechanism. If cleaning or replacement of the intercepting filter plate 3 is required, the components can be quickly separated by disassembling the second bolt 8 and the receiving core 2, significantly improving maintenance efficiency.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
