Description

Technical Field

[0001] This utility model relates to the field of ecological governance technology, specifically to a net-based device for blocking surface garbage in river management. Background Technology

[0002] In river ecological management and water environment maintenance, the interception and removal of surface and shallow underwater garbage is a key link, directly affecting water quality protection and the safe operation of water conservancy facilities. Currently, the mainstream garbage interception devices are mainly divided into two categories: floating pontoon barriers and fixed garbage racks. Floating pontoon barriers form an interception barrier by connecting pontoons with steel cables. Although they can be adjusted with the rise and fall of water level, the overall structure is mostly rigidly connected. When water flow impacts or garbage accumulates, they are prone to breakage due to stress concentration. Fixed garbage racks are fixed to the riverbed with concrete foundations. Although they have strong impact resistance, they cannot adapt to changes in water level and water flow direction. Moreover, they are prone to sudden increases in water flow resistance due to pore blockage, affecting the flood discharge capacity of the river.

[0003] Existing technologies suffer from insufficient impact resistance and adaptability. Most existing devices employ fixed connection structures, which lack effective stress relief mechanisms when encountering turbulent water flow or floating debris, making them prone to structural deformation or anchoring failure. This problem is particularly prominent during seasonal floods in mountainous rivers. Furthermore, their interception efficiency and ease of cleanup are poor. Existing devices primarily focus on intercepting surface debris, lacking sufficient ability to block shallow underwater debris. They also lack debris guiding structures, causing debris to easily accumulate and become stuck at the edges of the device, increasing the difficulty and cost of manual cleanup. Utility Model Content

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a net-based water surface garbage blocking device for river management, comprising a fixed cable, a plurality of positioning discs rotatably sleeved on the outer surface of the fixed cable, a lower float sleeved below the outer surface of the positioning discs, a connecting rod provided below the lower float, a plurality of guide wheels sleeved on the outer surface of the connecting rod, and a counterweight threaded to one end of the connecting rod.

[0014] (III) Beneficial Effects

[0015] This utility model provides a device for blocking surface garbage from fishing nets used in river management, which has the following beneficial effects:

[0016] This surface garbage interception device, used for river management, utilizes a lower float to provide buoyancy, ensuring its upper part is above the water surface. This effectively intercepts surface garbage. Multiple positioning discs work in conjunction with the lower float, allowing for relative rotation. When the lower float or connecting rod is impacted, the relative rotation of the lower float helps to dissipate the impact, preventing it from affecting the device's interception capability. The connecting rod and counterweight work together to block garbage sinking to the surface. Furthermore, the rotation of multiple guide wheels on the surface helps to block and guide underwater garbage, collecting it to a suitable location for easier processing by staff.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1 to 5 This utility model provides a garbage interception device, which is applied to the collection and interception of floating garbage during river management. This embodiment improves the structure of the garbage interception device to give it the advantages of buffering impact and guiding and intercepting garbage. Specifically, taking the collection and interception of floating garbage during river management as an example, as a preferred solution in this embodiment, the garbage interception device is specifically a surface garbage interception device using a fishing net for river management, capable of collecting and intercepting floating garbage.

[0025] Please see Figures 1 to 5 This utility model provides a technical solution: a net-based device for blocking floating garbage in river management. This garbage blocking device is mainly used in scenarios where floating garbage is collected and blocked during river management.

[0026] It includes a fixed cable 1, with multiple positioning discs 2 rotatably sleeved on the outer surface of the fixed cable 1, a lower float 4 sleeved below the outer surface of the positioning disc 2, a connecting rod 11 below the lower float 4, multiple guide wheels 12 sleeved on the outer surface of the connecting rod 11, and a counterweight 13 threadedly connected to one end of the connecting rod 11.

[0027] In this embodiment, the fixed cable 1 serves as the core support frame of the device, connecting all components such as the positioning discs 2 and the lower float 4. It also provides a mounting foundation for the device and a rotatable mounting carrier for the positioning discs 2, ensuring the overall structural integrity of the device and preventing component failure due to dispersion. This solves the problem of existing float-type devices where the steel cable only connects the floats and lacks rotational support. Simultaneously, it allows the positioning discs 2 to rotate around it, providing a structural foundation for subsequent stress relief and buffering, preventing breakage due to stress concentration in traditional rigid connections. The positioning disc 2 is the intermediate connector between the fixed cable 1 and the lower float 4, with the lower float 4 mounted on its outer surface and the fixed cable 1 rotatably mounted on its inner surface, thus realizing the connection between the fixed cable 1, the positioning discs 2, and the lower float 4. The flexible connection of float 4, utilizing its rotatable characteristic, allows the positioning plate 2 to rotate relative to the fixed cable 1 when the lower float 4 or connecting rod 11 is impacted by water flow or debris. This converts the impact force into rotational kinetic energy, achieving force relief and buffering. The lower float 4 provides core buoyancy for the device, ensuring that the upper part of the lower float 4 floats stably on the water surface. Simultaneously, it serves as the upper support carrier for the connecting rod 11, meeting the basic requirements for surface debris interception and preventing the entire device from sinking. Compared to traditional fixed debris barriers that cannot float and only intercept underwater debris, this device achieves dual interception at both the surface and shallow water levels. Combined with the positioning plate 2, it forms a combination of buoyancy and rotational buffering, ensuring both floating stability and impact resistance, thus solving the problems of traditional floats. To address the issues of single-source buoyancy and easy capsizing, the connecting rod 11 serves as a longitudinal support structure connecting the lower float 4 and the counterweight 13. It also provides a mounting platform for the guide wheel 12, acting as a direct barrier against shallow underwater debris. This fills the gap in existing devices that only intercept surface debris and neglect shallow underwater debris. The rod structure blocks floating objects while providing a stable base for the guide wheel 12, ensuring its functionality. Furthermore, by connecting the lower float 4 and the counterweight 13, it creates vertical force balance, preventing unilateral tilting. The guide wheel 12 rotates freely around the connecting rod 11, reducing water flow resistance and guiding intercepted surface and underwater debris towards a designated direction. The low water flow resistance of the device avoids the impact of traditional trash racks on flood discharge caused by clogging and sudden increase in water flow resistance. It also prevents garbage from accumulating and getting stuck at the edge of the device, guiding scattered garbage to a concentrated area. The counterweight 13 is fixed to one end of the connecting rod 11 by a threaded connection, increasing the weight of the lower part of the device, balancing the buoyancy of the lower float 4, and limiting the lateral displacement of the device in the water flow. It forms a balance system of upper buoyancy and lower counterweight with the lower float 4, preventing the device from tilting or drifting due to water flow impact. It solves the safety hazards of existing devices where the counterweight is not secure and is easy to fall off, and the balance fails. The threaded connection method facilitates installation and disassembly, and the weight of the counterweight can be adjusted according to the river depth and water flow speed, improving the environmental adaptability of the device.

[0028] In the above embodiments, as a preferred solution, end caps 3 are fixedly installed at the ends of the fixed cable 1. The top of the end cap 3 is provided with an insertion hole. The end cap 3 is fixed to both ends of the fixed cable 1 to prevent the positioning disc 2 from sliding off the end of the fixed cable 1. The insertion hole is used to insert a fixing component to anchor both ends of the fixed cable 1 to the shore or support, so as to prevent the positioning disc 2 from detaching from the fixed cable 1 during rotation or impact, thus ensuring the structural integrity. The insertion hole simplifies the installation process of the device. Compared with the complex anchoring method of traditional devices, it enables rapid positioning and fixing, and improves construction efficiency.

[0029] In the above embodiment, as a preferred solution, an upper float 5 is fitted onto the upper surface of the positioning disk 2. Mounting grooves 6 are provided on both sides of the outer surface of the upper float 5. The upper float 5 assists the lower float 4 in providing buoyancy. Fitted above the outer surface of the positioning disk 2, it forms a double-layered buoyancy structure with the lower float 4, enhancing the overall buoyancy of the device. This adapts to high water levels or high flow rates, preventing the device from sinking due to insufficient buoyancy of a single float, and improving the device's anti-overturning capability. Even if the lower float 4 is partially damaged, the upper float 5 can still provide buoyancy, reducing the risk of device failure. The mounting grooves 6 are located on both sides of the upper float 5, providing space for the fixing bolts 7 to be accommodated and installed, limiting the bolt's installation position, preventing misalignment during installation, ensuring precise connection between the upper float 5 and the lower float 4, and guaranteeing a tight connection between the two layers of floats.

[0030] In the above embodiment, as a preferred solution, the inner wall of the mounting groove 6 is threaded with a fixing bolt 7. One end of the fixing bolt 7 protrudes from the upper float 5 and is threadedly connected to the top of the lower float 4. The fixing bolt 7 eliminates the relative looseness between the upper float 5 and the lower float 4, avoids water flow impact causing the two to separate, ensures stable buoyancy output, and the detachable design facilitates float maintenance.

[0031] In the above embodiments, as a preferred option, a sealing ring 8 is fitted onto the outer surface of the fixing bolt 7. The bottom of the sealing ring 8 abuts against the inner wall of the mounting groove 6. By fitting the sealing ring 8 onto the outer surface of the fixing bolt 7 and abutting against the inner wall of the mounting groove 6, the gap between the bolt and the mounting groove 6 is sealed.

[0032] In the above embodiment, as a preferred solution, an installation plate 9 is fixedly installed on the bottom of the lower float 4, and multiple fixing seats 10 are fixedly installed on the bottom of the installation plate 9. The inner wall of the fixing seat 10 is threadedly connected to the other end of the connecting rod 11. The installation plate 9 is fixed to the bottom of the lower float 4 and serves as the installation carrier for the fixing seats 10. The fixing seats 10 are threadedly connected to the end of the connecting rod 11, thereby achieving a rigid connection between the lower float 4, the installation plate 9, the fixing seats 10 and the connecting rod 11. This disperses the force on the connecting rod 11, avoids excessive local stress and breakage of the lower float 4 caused by the connecting rod 11 being directly connected to the lower float 4, improves the structural strength, and the threaded fixing seats 10 facilitate the disassembly and replacement of the connecting rod 11.

[0033] In the above embodiments, as a preferred option, the inner walls of both the lower float 4 and the upper float 5 are provided with filler 14, which is mostly made of lightweight and high-strength material. This enhances the structural strength and buoyancy durability of the float, prevents the float from deforming due to water flow impact or debris collision, and the lightweight nature does not increase the overall weight of the device, ensuring stable buoyancy output and extending the service life of the device.

[0034] In this invention, the working steps of the device are as follows:

[0035] After the device enters the water, the lower float 4 and the upper float 5 together provide buoyancy, so that the upper part of the lower float 4 and the upper float 5 are completely above the water surface, while the connecting rod 11 and the guide wheel 12 are in shallow water, forming a double barrier of surface interception layer and underwater interception layer; when encountering turbulent water flow or floating object impact, the positioning plate 2 can rotate freely around the fixed cable 1, driving the lower float 4 and the connecting rod 11 to rotate slightly in sync, converting the impact force into rotational kinetic energy, and preventing the overall deformation of the device or loosening of the anchor point; at the same time, the counterweight 13 limits the lateral displacement of the device by its own weight, maintaining the stability of the interception position.

[0036] The device intercepts and guides the garbage. When surface garbage moves to the device with the water flow, it is blocked by the water surface barrier composed of the lower float 4 and the upper float 5, and cannot continue to flow downstream. When shallow underwater garbage impacts the connecting rod 11 with the water flow, it is blocked by the connecting rod 11. At the same time, the guide wheel 12 is pushed to rotate freely by the water flow or garbage, guiding the garbage along the tangential direction of the guide wheel 12 to the preset garbage concentration area, so as to avoid garbage accumulating and getting stuck at the edge of the device.

[0037] Regularly observe the garbage accumulation in the device. When the amount of garbage in the concentrated area reaches a certain level, staff can use boats or operate nets on the shore to directly collect and clean the garbage on the surface and underwater of the concentrated area. This eliminates the need for point-by-point inspection, reducing the difficulty of cleaning. During the cleaning process, the guide wheel 12 rotates continuously, which can help push the garbage that has not been completely gathered towards the cleaning area, improving the cleaning efficiency.

[0038] If the interception depth needs to be adjusted, the counterweight 13 can be unscrewed, replaced with a counterweight of different weight, and then reinstalled. If the river water level changes over a long period of time, the anchoring height of the fixing cable 1 can be adjusted to ensure that the float is always in a reasonable interception position.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
