Description

Technical Field

[0001] This utility model relates to the field of floating object collection technology, specifically to a non-powered automatic collection device for floating objects in river channels. Background Technology

[0002] With the acceleration of urbanization and the increasing frequency of industrial activities, the problem of floating debris pollution in waterways such as rivers and ditches has become increasingly serious. These floating objects not only damage the aesthetics of the waterways but also have a severe negative impact on water quality and the aquatic ecosystem.

[0003] Currently, the removal of floating debris in rivers mainly relies on two methods: manual dredging and mechanical cleaning. Manual dredging is inefficient, requires a large workforce, and poses safety risks to workers in adverse weather conditions. While mechanical cleaning improves efficiency to some extent, it also has several drawbacks. Firstly, mechanical cleaning equipment typically consumes significant amounts of energy, increasing operating costs. Secondly, the purchase and maintenance costs of such equipment are high, making it unaffordable for some economically disadvantaged areas. Furthermore, some mechanical cleaning equipment is poorly adaptable to different water conditions, proving ineffective in narrow, winding, or waters with significant depth variations. Therefore, this application proposes an energy-saving, environmentally friendly, low-cost, highly efficient, and adaptable river floating debris collection device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the aforementioned technologies by providing a non-powered automatic collection device for floating debris in river channels. This device requires no external power source and utilizes the kinetic energy of the water flow itself to automatically collect the debris. It has advantages such as energy saving, environmental protection, low cost, high efficiency, and convenient maintenance, and can effectively solve the problems existing in current methods of cleaning floating debris in river channels.

[0005] This utility model provides a non-powered automatic collection device for floating debris in river channels, comprising: A floating platform with curved guide vanes mounted on it; The float is mounted on a floating platform; The barrier net is detachable and can be installed on the floating platform. The collection frame is detachably located at the bottom of the floating platform; The fixed rod is fixed in the river by a weight, and the floating platform is slidably mounted on the fixed rod by a sliding frame, with the collection frame located inside the sliding frame.

[0006] Preferably, the floating platform is provided with multiple curved guide plates, and two adjacent curved guide plates facing each other form a V-shaped guide channel; the net is composed of multiple pieces, and the net is inclined behind the V-shaped guide channel. Multiple connecting grooves are provided circumferentially in the middle of the floating platform, and connecting protrusions are provided on both sides of the net. The net can be detachably slidably installed in the connecting grooves through the connecting protrusions.

[0007] Preferably, the float includes a rhomboid guide portion and a rectangular insertion portion. An insertion groove is provided at the lower part of the float platform. The rectangular insertion portion is inserted into the insertion groove. The rhomboid guide portion is fitted with two adjacent curved guide plates to form an extended guide structure.

[0008] Preferably, the floating platform has a circular through hole in the middle, and the collection frame has a limiting through hole in the middle. The collection frame is sleeved on the fixed rod through the limiting through hole and placed on the sliding frame through the circular through hole.

[0009] Preferably, the barrier net includes a net frame, a first elastic lever, and a second elastic lever. The net frame has a trapezoidal or arc-shaped structure. The first elastic lever is connected to the upper and lower ends of the net frame via connectors at both ends. The second elastic lever is connected to the upper and side ends of the net frame via inserts at both ends and connectors at both ends. Both the first and second elastic levers are provided with silicone hemispherical protrusions.

[0010] Preferably, it also includes a water baffle, which is a plurality of baffles. A rectangular plate is provided on the fixing rod, and the plurality of baffles are inclined on the rectangular plate in the circumferential direction.

[0011] Preferably, the upper end of the fixing rod is detachably threaded with a sleeve, and the end of the sleeve is provided with a spring, which abuts against the water baffle.

[0012] Preferably, a limit ring is provided on the rectangular plate, and a limit rod is provided on the floating platform, with the limit ring sliding on the limit rod.

[0013] Compared with existing technologies, it has the following beneficial effects:

[0014] By installing curved guide plates and nets on the floating platform, and relying on the design of the curved guide plates, multiple V-shaped guide channels are formed on the floating platform to collect floating debris from different directions on the water surface. It can effectively function in narrow, winding, or water depth-varying waters. Moreover, this device does not require an external power source, but mainly relies on the kinetic energy of the water flow to achieve automatic garbage collection, which has the advantages of energy saving, environmental protection, low cost, high efficiency, and convenient maintenance. By setting a sliding frame on the fixed rod and fixing the floating platform on the sliding frame, the limiting effect of the fixed rod in the water and the buoyancy of the float allow the floating platform to automatically adjust its height in real time according to the water level in the river channel, so as to ensure that the floating platform is always on the water surface to collect floating debris. At the same time, the sliding frame with a rotating design allows the floating platform to rotate on the fixed rod under the action of the water flow, thereby adjusting the position of the four V-shaped guide channels to facilitate the collection of floating debris from different directions. Additionally, the position of the clogged V-shaped guide channel can be adjusted by rotation, thereby using reverse water flow to flush away the blockage and effectively reduce the occurrence of blockage, further improving the collection efficiency of floating debris.

Detailed Implementation

[0017] To better understand the structure, functional features, and advantages of this utility model, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings: Example: like Figures 1 to 12 As shown, this application proposes a non-powered automatic collection device for floating debris in river channels, comprising: Floating platform 1, on which curved guide vanes 11 are installed; Float 2 is mounted on floating platform 1; Netting 3 is detachably mounted on floating platform 1; The collection frame 4 is detachably located at the lower part of the floating platform 1; multiple handles 41 are provided around the circumference of the collection frame 4 to facilitate the removal of the collection frame 4 from the floating platform 1. The fixed rod 5 is fixed in the river by the weight 6. The floating platform 1 is slidably mounted on the fixed rod 5 by the sliding frame 7. The collection frame 4 is located inside the sliding frame 7 so that the sliding frame 7 can drive the floating platform 1 to rotate on the fixed rod 5, thereby adjusting the position of the floating platform 1 on the water surface in real time.

[0018] See Figure 2 The floating platform 1 is equipped with multiple curved guide plates 11, and two adjacent curved guide plates 11 facing each other form a V-shaped guide channel 12; the net 3 consists of multiple pieces, and the net 3 is inclined behind the V-shaped guide channel 12. Furthermore, in this embodiment, there are four V-shaped guide channels 12. The four V-shaped guide channels 12 collect floating objects from multiple directions. Through the design of the rotatable floating platform 1, the V-shaped guide channels 12 can rotate with the water flow while collecting floating objects from multiple directions, which can effectively play a role in narrow, winding or water depth-varying waters.

[0019] See Figure 3 and Figure 5The floating platform 1 is inclined in the circumferential direction in the middle and has multiple connecting grooves 15. The netting 3 is provided with connecting protrusions on both sides. The netting 3 can be detachably slidably installed in the connecting grooves 15 through the connecting protrusions.

[0020] Furthermore, the connecting groove 15 has a "V"-shaped structure with a larger upper part and a smaller lower part, which limits the position of the netting 3 that is slidably inserted into the connecting groove 15. Furthermore, the upper part of the netting 3 is provided with a snap-fit ​​part or a connecting part to fix the netting 3 into the connecting groove 15. The snap-fit ​​part can be connected by a fastening method, and the connecting part uses a connecting piece with threaded holes to connect to the upper end face of the connecting groove 15 by bolts.

[0021] See Figure 8 The float 2 includes a rhomboid guide section 21 and a rectangular insertion section 22. The lower part of the float 1 is provided with an insertion groove 13. The rectangular insertion section 22 is inserted into the insertion groove 13. The rhomboid guide section 21 is fitted with two adjacent curved guide plates 11 to form an extended guide structure, so as to collect floating objects with a larger V-shaped guide channel.

[0022] See Figure 4 A circular through hole 14 is provided in the middle of the floating platform 1, and a limiting through hole is provided in the middle of the collection frame 4. The collection frame 4 is sleeved on the fixed rod 5 through the limiting through hole and placed on the sliding frame 7 through the circular through hole 14.

[0023] See Figure 17 Multiple collection units in a linear structure, consisting of multiple automatic collection devices, can be combined to increase the coverage of the collection devices; or multiple automatic collection devices can be arranged in a V-shape.

[0024] See Figure 18 The S-shaped structure consists of multiple collection units, which combine multiple automatic collection devices to increase the coverage of the collection devices through multiple combinations.

[0025] The working principle of this embodiment is as follows: When the device is placed in the river, the water flows through the V-shaped guide channel 12 of the device. Under the action of the curved guide plate 11, the direction and speed of the water flow change, forming a specific water flow direction, guiding the garbage into the area of ​​the net 3. The net 3, which is inclined and set behind the V-shaped guide channel 12, can effectively guide floating objects into the collection frame 4. At the same time, by rotating the sliding frame 7 sleeved on the fixed rod 5, the floating platform 1 can rotate on the water surface under the buoyancy of the floating body 2 and the action of the water flow, so as to collect floating objects from water flows in all directions.

[0026] As another embodiment of this utility model, such as Figures 7 to 12As shown, the barrier net 3 includes a frame 31, a first elastic lever 32, and a second elastic lever 33. The frame 31 has a trapezoidal or arc-shaped structure. The first elastic lever 32 is connected to the upper and lower ends of the frame 31 via connectors at both ends. The second elastic lever 33 is connected to the upper and side ends of the frame 31 via inserts 34 and connectors 35 at both ends, respectively. Inserts 34 and connectors 35 are inserted into slots 311 on all four sides of the frame 31 for positioning, and are fixedly connected to the frame 31 using bolts via threaded holes on inserts 34 and connectors 35 and connecting holes 312 on all four sides of the frame 31.

[0027] See Figure 12 The elastic lever 32 and the elastic lever 33 are equipped with silicone hemispherical protrusions. This design allows the elastic lever to better adapt to the shape and size of the garbage when it is moved. At the same time, the silicone hemispherical protrusions can effectively prevent weeds and other debris from getting tangled on the lever, thus improving garbage collection efficiency.

[0028] Furthermore, a metal rod can be used to replace the elastic lever 32 and the elastic lever 33.

[0029] The working principle of this embodiment is as follows: When the device is placed in the river, the water flows through the V-shaped guide channel 12 of the device. Under the action of the curved guide plate 11, the direction and speed of the water flow change, forming a specific water flow direction, guiding the garbage to the area of ​​the elastic lever 32 and elastic lever 33 of the screen 3. The elastic lever 32 and elastic lever 33 use their own elasticity and the silicone hemispherical protrusions on their surfaces to push the garbage into the collection frame 4 of the grid structure. When the collection frame 4 is full, the screen 3 can be disassembled, and the collection frame 4 located in the sliding frame 7 can be removed by sliding it from the fixed rod 5. The operator can disassemble the collection frame 4 by hand for cleaning, and after cleaning, it can be reinstalled for continued use.

[0030] As another embodiment of this utility model, such as Figures 13 to 15 As shown, it also includes a water baffle 8, which consists of multiple pieces. A rectangular plate 81 is provided on the fixing rod 5. The multiple water baffles 8 are inclined around the rectangular plate 81. The water baffles 8 allow the water to flow through the net 3 and then into the collection frame 4.

[0031] Furthermore, a sleeve is detachably threaded to the upper end of the fixed rod 5, and a spring is installed at the end of the sleeve, which abuts against the baffle plate 8. By setting the spring, when the water flows through the V-shaped guide channel 12 into the barrier net 3, it comes into contact with the baffle plate 8, and the water flow changes direction, causing repeated pressure. This causes the floating platform 1 to move back and forth on the water surface along the axial direction of the fixed rod 5, thereby realizing the elastic shaking effect of the floating platform 1, which can further reduce the occurrence of clogging problems.

[0032] Furthermore, the end of the sleeve is provided with an internal thread, and the end of the fixing rod 5 is provided with an external thread. The sleeve is connected to the fixing rod 5 via the internal thread to adjust the position of the spring on the fixing rod 5. One end of the spring is rotatably mounted on the end of the sleeve via a swivel ring, and the spring can rotate relative to the sleeve. To prevent the sleeve from rotating during the rotation of the floating platform 1, multiple limiting holes are evenly distributed in the vertical direction of the fixing rod 5, and locking holes are provided on the sleeve. The sleeve is locked to the fixing rod 5 by means of pins or bolts.

[0033] See Figure 16 A limiting ring 82 is provided on the rectangular plate 81, and a limiting rod 16 is provided on the floating platform 1. The limiting ring 82 slides on the limiting rod 16 to limit the rectangular plate 81, so that the four baffles 8 on the rectangular plate 81 can be set in sequence to correspond to the four nets 3, so that the baffles 8 can also be driven to rotate together when the floating platform 1 rotates.

[0034] Furthermore, triangular blocks are evenly spaced on the baffle plate 8, which can clear blockages inside the netting 3 during the vertical relative movement of the baffle plate 8 and the netting 3.

[0035] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of this utility model without departing from the scope of the technical solution of this utility model shall fall within the protection scope of this technical solution.
