Description
Technical Field
[0001] This utility model relates to the field of river management technology, specifically to a floating buoy for intercepting floating debris in river management. Background Technology
[0002] One aspect of river management is intercepting floating debris on the river surface. The common method involves setting up several interception pontoons to intercept the debris. Traditional interception pontoon systems (usually a debris-blocking system consisting of pontoons connected in series) are designed with a focus on the single function of "interception," while seriously neglecting the subsequent stages of "collection, transfer, and treatment," resulting in a "half-finished project."
[0003] Traditional floating chain barriers, laid across the river, cause floating debris to be evenly distributed along the barrier line rather than being guided to a specific area, resulting in highly dispersed trash. Furthermore, due to delayed cleanup, the intercepted trash (especially plastic products) remains submerged in the water for extended periods, breaking down into smaller microplastics and exacerbating water pollution. Summary of the Invention
[0004] To solve the aforementioned technical problems, this technical solution provides a floating pontoon for intercepting floating debris in river management, thus addressing the issues raised in the background section.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: The floating debris interception pontoon for river management includes a frame and a pontoon and a collection frame fixedly mounted on the frame. Two sets of floats are symmetrically fixedly mounted on the collection frame. The lower end of the float is fixedly connected to an underwater frame. A deflector for pushing floating debris is provided on the upper side of the float. A drive assembly for driving the deflector is provided on the underwater frame. The drive assembly includes a mounting box fixedly connected to the underwater frame. The mounting box has a water inlet channel. A filter screen is provided on the water inlet channel. A cleaning assembly is provided on the outside of the filter screen. A turbine blade driven by water flow is rotatably mounted inside the mounting box. A rotating shaft is fixedly mounted on the turbine blade. The top end of the rotating shaft is fixedly connected to the deflector, and the rotating shaft synchronously drives the cleaning assembly.
[0006] Preferably, the right side of the installation box is provided with an inlet and an outlet. The inlet channel is fixedly installed on the installation box and is located outside the inlet. Filter screen one is fixedly installed at the front end of the inlet channel, and filter screen two is fixedly installed inside the outlet. A guide plate one is fixedly connected inside the inlet channel, and a guide plate two is fixedly installed on the right side of the guide plate one.
[0007] Preferably, a bevel gear is fixedly installed on the rotating shaft, the front end of the bevel gear meshes with the cleaning component, and a waterproof shell fixedly installed on the floating plate is provided on the outer side of the bevel gear.
[0008] Preferably, the cleaning assembly includes a second bevel gear meshing with a first bevel gear, a drive shaft fixedly connected to the second bevel gear, the front end of the drive shaft passing through the waterproof housing and fixedly connected to a crank arm, and the drive shaft rotatably connected to the waterproof housing; a connecting rod is rotatably mounted on the crank arm, a cleaning brush for cleaning the first filter screen is provided on the lower side of the connecting rod, a connecting seat is fixedly connected to the upper end of the cleaning brush, and the lower end of the connecting rod is rotatably connected to the connecting seat; a limiting assembly for limiting the movement of the cleaning brush is provided on the water inlet channel.
[0009] Preferably, the limiting component includes a slide rail fixedly installed on the water inlet channel, a slider slidably connected inside the slide rail, and the front end of the slider being fixedly connected to the cleaning brush.
[0010] Preferably, both ends of the frame are fixedly connected to a placement rack, and the placement rack is used to place the counterweight.
[0011] Compared with existing technologies, the present invention proposes a floating pontoon for intercepting floating debris in river management, which has the following beneficial effects: This invention incorporates turbine blades that convert the kinetic energy of the water flow into rotational mechanical energy. This rotational power is then transmitted via a shaft to an upper deflector and cleaning assembly. The deflector continuously pushes floating debris onto the water surface and into the collection box, completing the retrieval process. Compared to passive interception, the active retrieval by the deflector is more efficient and avoids debris accumulation. Furthermore, the turbine blades are driven by the natural flow of the river, eliminating the need for external electricity or fuel, making them energy-saving and environmentally friendly. They can operate continuously for 24 hours, effectively reducing operating and maintenance costs. The cleaning component transmits power through bevel gear one and bevel gear two, which, in conjunction with the drive shaft, converts the rotational motion into the circular motion of the crank arm. Then, through the connecting rod and slide rail slider mechanism, the circular motion of the crank arm is converted into the linear reciprocating motion of the cleaning brush, which brushes back and forth on the surface of filter screen one to remove the debris attached to it, prevent filter screen one from clogging, ensure the continuity of the water inlet channel, and thus ensure the long-term stable operation of the entire drive component, reducing the frequency of manual maintenance.

Detailed Implementation
[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Reference Figure 1 and Figure 3 As shown, the floating debris interception pontoon for river management includes a frame 1 and a pontoon 2 and a collection frame 3 fixedly installed on the frame 1. Two sets of floats 4 are symmetrically fixedly installed on the collection frame 3. The lower end of the floats 4 is fixedly connected to an underwater frame 5. A deflector 6 for pushing floating debris is provided on the upper side of the floats 4. A drive assembly 7 for driving the deflector 6 is provided on the underwater frame 5.
[0017] Specifically, the drive assembly 7 is equipped with turbine blades 705. The turbine blades 705 are driven by the natural water flow of the river, without the need for external electricity or fuel power. They can work continuously for 24 hours, are energy-saving and environmentally friendly, and are applicable to a wide range of areas. By transmitting the rotational power generated by the turbine blades 705 to the upper deflector 6 and the cleaning assembly 8, the deflector 6 can continuously push floating objects on the water surface into the collection frame 3 to complete the retrieval action. Compared with passive interception, the active retrieval by the deflector 6 is more efficient and can avoid the accumulation of garbage.
[0018] This invention is particularly suitable for water bodies with stable flow velocities, such as rivers, reservoir inlets, and inlets of hydropower stations, where the flow velocity is sufficient to drive turbines efficiently.
[0019] Reference Figure 4 and 5 As shown, specifically in this embodiment, the drive assembly 7 includes a mounting box 701 fixedly connected to the underwater frame 5. The mounting box 701 is provided with a water inlet channel 702. A filter screen 703 is provided on the water inlet channel 702. A cleaning assembly 8 is provided on the outside of the filter screen 703. A turbine blade 705 driven by water flow is rotatably mounted inside the mounting box 701. A rotating shaft 706 is fixedly mounted on the turbine blade 705. The top end of the rotating shaft 706 is fixedly connected to the deflector plate 6, and the rotating shaft 706 synchronously drives the cleaning assembly 8.
[0020] The kinetic energy of the water flow drives the turbine blades 705, converting it into mechanical energy that rotates the turbine blades 705. This mechanical energy is then transmitted through the rotating shaft 706 to the upper baffle plate 6.
[0021] Reference Figure 4 As shown, specifically in this embodiment, the right side of the mounting box 701 is provided with a water inlet and a water outlet. The water inlet channel 702 is fixedly installed on the mounting box 701 and is located outside the water inlet. The first filter screen 703 is fixedly installed at the front end of the water inlet channel 702, and the second filter screen 704 is fixedly installed inside the water outlet. The inside of the water inlet channel 702 is fixedly connected with a first guide plate 707, and the right side of the first guide plate 707 is provided with a second guide plate 708 fixedly installed on the mounting box 701.
[0022] By using filter screen 703 and filter screen 704 together, weeds, plastic and other debris are effectively prevented from entering the installation box 701, jamming the turbine blades 705 or blocking the water flow channel, thus ensuring that the drive assembly 7 can work stably and normally.
[0023] At the same time, such as Figure 4As shown, the water flow pattern in the inlet channel 702 is optimized by the cooperation of the first guide plate 707 and the second guide plate 708, so that the water flow impacts the turbine blades 705 more concentratedly and smoothly, reducing eddies and energy loss, and improving energy conversion efficiency. Reference Figure 5 As shown, specifically in this embodiment, a bevel gear 709 is fixedly installed on the rotating shaft 706. The front end of the bevel gear 709 meshes with the cleaning component 8, and a waterproof shell 7010 is fixedly installed on the floating plate 4 on the outer side of the bevel gear 709.
[0024] The waterproof housing 7010 effectively protects transmission components such as bevel gears from water impact and mud erosion, extending their service life and ensuring transmission reliability.
[0025] Reference Figure 5 and Figure 6 As shown, specifically in this embodiment, the cleaning component 8 includes a second bevel gear 801 meshing with a first bevel gear 709. A drive shaft 802 is fixedly connected to the second bevel gear 801. The front end of the drive shaft 802 passes through the waterproof housing 7010 and is fixedly connected to a crank arm 803. The drive shaft 802 is rotatably connected to the waterproof housing 7010. A connecting rod 804 is rotatably mounted on the crank arm 803. A cleaning brush 807 for cleaning the first filter screen 703 is provided on the lower side of the connecting rod 804. A connecting seat 808 is fixedly connected to the upper end of the cleaning brush 807. The lower end of the connecting rod 804 is rotatably connected to the connecting seat 808. A limiting component for limiting the movement of the cleaning brush 807 is provided on the water inlet channel 702.
[0026] Furthermore, a wear-resistant and corrosion-resistant sealing ring is provided between the smooth surface of the drive shaft 802 and the waterproof housing 7010.
[0027] Reference Figure 6 As shown, specifically in this embodiment, the limiting component includes a slide rail 805 fixedly installed on the water inlet channel 702, a slider 806 slidably connected inside the slide rail 805, and the front end of the slider 806 fixedly connected to the cleaning brush 807.
[0028] Limit the movement of the cleaning brush 807 to ensure it moves smoothly in a straight line and effectively scrape away the blockages on the filter screen 703.
[0029] In the cleaning assembly 8, the rotating shaft 706 drives the bevel gear 709 to rotate. The bevel gear 709 then transmits power through the meshing bevel gear 801, driving the transmission shaft 802 to rotate, which in turn drives the outer crank arm 803 to rotate. This converts the rotational motion of the rotating shaft 706 into the circular motion of the crank arm 803. Then, through the connecting rod 804, slide rail 805, and slider 806, the circular motion of the crank arm 803 is converted into the linear reciprocating motion of the cleaning brush 807, which brushes back and forth on the surface of the filter screen 703 to remove the debris attached to it. The removed debris can be naturally washed away by the water flow (such as a river with a stable flow rate), preventing the filter screen 703 from clogging, ensuring the continuity of the water inlet channel 702, and thus ensuring the long-term stable operation of the entire drive assembly 7 and reducing the frequency of manual maintenance.
[0030] Reference Figure 2 As shown, specifically in this embodiment, both the left and right ends of the frame 1 are fixedly connected to a placement rack 101, and the placement rack 101 is used to place the counterweight 102.
[0031] By increasing or decreasing the number of counterweights 102 placed in the mounting frame 101, the overall weight of the frame 1 is adjusted, thereby adjusting the overall draft of the device in the water flow and ensuring the stability and reliability of the equipment under different water flow conditions. By lowering the center of gravity of the equipment, the overall stability is improved, preventing it from tipping over or shaking excessively in the flowing water.
[0032] In use, this invention utilizes the cooperation of guide plates 707 and 708 to optimize the water flow pattern within the inlet channel 702. This allows the water flow to impact the turbine blades 705 more concentratedly and smoothly, converting the kinetic energy of the water flow into the mechanical energy of the turbine blades 705's rotation. This mechanical energy is then transmitted via the rotating shaft 706 to the upper deflector plate 6, which continuously pushes and guides floating debris onto the water surface into the collection frame 3, completing the retrieval process. The collection frame 3 can further connect to an onshore conveyor system for centralized transfer and processing.
[0033] The various embodiments in this specification are described in a related manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.
[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
