Description

Technical Field

[0001] This invention relates to the field of ecological restoration technology, specifically to an ecological floating raft with an opening and closing function. Background Technology

[0002] Chinese patent CN111422992A discloses an intelligent ecological floating island with pollution interception function. This type of device effectively collects floating garbage and large underwater particulate pollutants in black and odorous water bodies by setting up a three-dimensional pollution interception method on the surface of the water body and using the filter plate of the grid structure below the water surface. It also effectively absorbs pollutants in black and odorous water bodies that cannot be collected and filtered by forming a pollution-resistant plant community.

[0003] However, the floating island does not span the waterway, making it impossible to completely block the flow of water, resulting in poor ecological management. However, if the floating island were to span the waterway, it would restrict the passage of ships, greatly reducing water transport capacity. Furthermore, if ships were to force their way through, the propellers at their sterns could easily damage the blocking device. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an ecological floating raft with an opening and closing function, thus solving the problems raised in the background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an ecological floating raft with opening and closing function, including a floating raft frame; an interception and transmission net located on the upper inner side of the floating raft frame to intercept and collect floating debris in the water flow; ecological plants located at the upper end of the floating raft frame, offset from the interception and transmission net, to adsorb pollutants in the intercepted water flow; a delay shell located on one side of the floating raft frame, with a rotating shaft inside providing rotation for the floating raft frame, so that the floating raft frame opens along the rotating shaft when thrust by a vessel in the water flow, providing a passage for the vessel; and a delay component located inside the delay shell, used to apply a delayed reset force to the rotating shaft, so that after the vessel leaves the floating raft frame, the floating raft frame resets after a delay and is offset from the stern propeller.

[0006] Furthermore, it also includes: a swing shell, which is located below the delay shell and is fixedly connected to the delay shell via a telescopic frame. The middle of the swing shell has a support seat connected to the telescopic frame, so that when the floating platform is thrust by the ship, it drives the telescopic frame to swing around the support seat as the axis; a support platform, which is provided in two sets, respectively located on both sides of the telescopic frame. The upper part of the support platform is provided with a lever connected to the telescopic frame, so that the swing thrust of the telescopic frame pushes the support platform to move in a linkage manner; a drive gear, which is located at the bottom of the telescopic frame, and a driven gear meshes below the drive gear. A rack connected to the support platform meshes below the driven gear, so that the swing thrust of the telescopic frame pushes the support platform to move in a gear mesh manner.

[0007] Furthermore, it also includes pressure guide rods located at the upper and lower ends of the support platform, with a pressure spring at the other end of the pressure guide rod providing displacement reset for the support platform.

[0008] Furthermore, the delay components are configured in two groups, which are arranged in opposite directions, so that when the floating platform is opened by the thrust of the ship, one group of delay components delays and stores force, while the other group is not subjected to force.

[0009] Furthermore, the delay component includes: a first support ring disposed on the delay shell, a compression spring disposed above the first support ring, and a toothed disc disposed at the other end of the compression spring; and a second support ring disposed on the rotating shaft away from the toothed disc, with a toothed seat on the edge of the second support ring that meshes with the toothed disc in a misaligned manner.

[0010] Furthermore, the teeth of the toothed disc are arranged in a fan-shaped structure, and the tooth grooves of the toothed disc gradually deepen along the rotation direction of the tooth base.

[0011] Furthermore, the delay component also includes: a fixing sleeve, which is disposed on the delay shell away from the second support ring, and a plurality of guide rings are provided inside the fixing sleeve. The guide rings are provided with a stepped arrangement of return springs along their circumference, and the other end of the return spring is provided with a pressure block; an impact block, which is disposed on the rotating shaft around the guide ring, and the impact block is driven by the rotation of the rotating shaft to contact the pressure block in sequence.

[0012] Furthermore, the lower interior of the floating platform is provided with at least one set of turbine fans, and there is a drive component between the turbine fans and the interception and transmission net, so that the turbine fans are rotated by the water flow, converting the water flow force into rotational thrust to drive the interception and transmission net to rotate, and to collect the floating objects intercepted on the interception and transmission net by self-transmission.

[0013] Furthermore, the drive assembly includes: a drive shaft disposed on the back plate of the turbine fan away from the interception transmission net; a central shaft disposed on the impeller shaft of the turbine fan, with a first bevel gear at the other end of the central shaft, the first bevel gear meshing with a second bevel gear disposed on the drive shaft, so that the rotational force of the turbine fan impeller is transmitted to the drive shaft; and a transmission shaft, which is configured as three sets arranged in a star-delta pattern and respectively disposed on the inner and outer belt surfaces of the interception transmission net, with a transmission worm gear at one end of the transmission shaft, the transmission worm gear meshing with a transmission worm disposed on the drive shaft, so that the rotational driving force of the drive shaft is transmitted to the transmission shaft, thereby applying a transmission driving force to the interception transmission net.

[0014] Furthermore, it also includes: a net frame, which is located outside the ecological plants and fixed to the floating frame; a planting board, which is located inside the net frame to form a planting platform for the ecological plants, and an adsorption cavity for the growth of the ecological plant roots is reserved between the planting board and the net frame, so that the roots of the ecological plants can grow and extend into the adsorption cavity to adsorb pollutants in the water flowing into the adsorption cavity.

[0015] The present invention has the following beneficial effects:

[0016] (1) The ecological floating raft with opening and closing function has the characteristic of adsorbing water pollutants through the setting of ecological boxes. While using the interception and transmission network to intercept and collect floating objects such as garbage in the water, it can also ecologically adsorb pollutants in the intercepted water flow, and the interception effect is more significant.

[0017] (2) The ecological floating raft with opening and closing function has the characteristic of rotating to open and delaying to reset by setting the delay component. When passing ships, the floating raft is rotated to open by the thrust of the ships in the water, providing a passage for the ships. After the ships pass, it rotates to reset after a delay, and is offset from the stern propeller to avoid collision damage. Under the rotation support of the delay component, the floating raft also has the characteristic of rotation decompression. When the water flow is rapid during the rainy season, the rapid water flow drives the floating raft to rotate in line with the water flow, so as to reduce the lateral impact force of the water flow on it and avoid the floating raft from drifting and being lost due to excessive impact.

[0018] (3) The ecological floating raft with opening and closing function has a telescopic frame with front and rear swing reset characteristics at one end of the floating raft frame. This allows the floating raft frame to have the effect of intercepting floating objects in a fixed state, while also having the swing clearance characteristics when the ship is pushing it. When the ship pushes the floating raft frame to rotate and open, the floating raft frame swings back and forth with the ship's thrust to reduce pressure, thereby reducing the hard impact force of the ship on the floating raft frame and improving the self-protection capability of the floating raft frame.

[0019] (4) The ecological floating raft with opening and closing function has an interception and transmission net set at the upper end of the floating raft frame and a turbine fan set at the lower end of the floating raft frame. The turbine fan rotates under the water flow and transmits the rotation force to the interception and transmission net through the drive component. This allows the interception and transmission net to intercept floating objects on the river surface while also having the characteristics of self-transmission and collection. This reduces the difficulty of subsequent cleaning and provides better continuity and better interception effect for floating objects.

[0020] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0042] Please see Figures 1-18 This invention provides a technical solution: an ecological floating raft with an opening and closing function.

[0043] Please see Figure 1 , Figure 2 as well as Figures 12-18An ecological floating raft with opening and closing function includes a floating raft frame 7. To enable the floating raft frame 7 to intercept and collect floating objects in the water area on a daily basis, an interception and transmission net 8 is provided on the upper side of the interior of the floating raft frame 7, and at least one set of turbine fans 9 is provided on the lower side of the interior of the floating raft frame 7. A drive component is provided between the interception and transmission net 8 and the turbine fans 9. When the floating raft frame 7 is used to intercept floating objects in the water area on a daily basis, the interception and transmission net 8 floats on the water surface to intercept floating objects on the river surface, while the turbine fans 9 are submerged underwater. When the water flow is present, it applies a thrust to the turbine fans 9, which drives the turbine fans 9 to rotate. Then, the turbine fans 9 transmit the rotational force to the interception and transmission net 8 through the drive component, which drives the interception and transmission net 8 to rotate, and the floating objects intercepted on the interception and transmission net 8 are automatically transferred, collected, and summarized.

[0044] Please see Figures 1-2 , Figures 12-13 To achieve ecological adsorption and interception of floating debris in the water, an ecological box 13 consisting of a net frame 111, a planting board 112, and ecological plants 113 is installed on the floating frame 7. The ecological adsorption of the ecological plants 113 in the ecological box 13 is used to adsorb pollutants in the water flow. The net frame 111 is fixed to the upper end of the floating frame 7. The planting board 112 is installed in the net frame 111 as a planting platform for the ecological plants 113. An adsorption cavity 114 for the root growth of the ecological plants 113 is reserved between the planting board 112 and the net frame 111, so that the roots of the ecological plants 113 can grow into the adsorption cavity 114 and adsorb pollutants in the water flow that flows into the adsorption cavity 114.

[0045] It should be noted that ecological plant 113 can be selected from plants that float on the water surface, such as water hyacinth, duckweed, and water onion. While ecologically absorbing pollutants such as nitrogen, phosphorus, and heavy metals in the water, their floating characteristics can minimize the contact between the bow of the boat and its branches and leaves when the boat passes by.

[0046] Furthermore, anti-collision airbags 10 are arranged at equal intervals on both sides of the upper end of the floating platform 7, so that when ships pass through the waterway, the anti-collision airbags 10 will contact the ships to avoid direct collision with the floating platform 7 and reduce the collision thrust generated when the ships push the floating platform 7. At the same time, the anti-collision airbags 10 can also protect the ecological plants 113 and prevent ships from touching the ecological plants 113.

[0047] To facilitate opening and closing, this embodiment also includes a delay shell 5 located on one side of the float frame 7. Inside the delay shell 5 is a rotating shaft 24 that allows the float frame 7 to rotate. When the float frame 7 is thrust by a vessel, it rotates along the rotating shaft 24 to open, providing a passage for the vessel. A delay component is also located inside the delay shell 5 to apply a delayed reset force to the rotating shaft 24. During routine interception of floating debris in the water using the interception device, the float frame 7 floats on the water surface to intercept and collect floating debris. Since the interception device is usually positioned across the water surface, when passing vessels pass, the rotating shaft 24 enables the floating platform 7 to rotate. Under the thrust of the vessels in the water, the platform rotates along the rotating shaft 24 to open, providing a passage for the vessels. Furthermore, by utilizing the delayed reset characteristic of the delay component, a delayed reset force is applied to the rotating shaft 24. After the vessels leave the floating platform 7, the rotating shaft 24 resets after a delay, causing the floating platform 7 to reset in a delayed manner, which is different from the reset of the stern propeller, thus preventing the propeller from damaging the floating platform 7.

[0048] As a further embodiment of this solution, the drive assembly includes a drive shaft 13 located on the back plate of the turbine fan 9 away from the interception transmission network 8. The impeller shaft of the turbine fan 9 is provided with a central shaft 38, and the other end of the central shaft 38 is provided with a first bevel gear 39. The first bevel gear 39 meshes with a second bevel gear 42 provided on the drive shaft 13. When the turbine fan 9 is rotated by the water flow, it drives the central shaft 38 to rotate, which in turn drives the first bevel gear 39 to rotate. By utilizing the meshing transmission between the first bevel gear 39 and the second bevel gear 42, the drive shaft 13 is driven to rotate, so that the impeller rotational force of the turbine fan 9 is transmitted to the drive shaft 13, which serves as the drive source for driving the interception transmission network 8.

[0049] It should be noted that a fixed bushing 40 is provided on the drive shaft 13, and a tension spring 41 is provided on the fixed bushing 40. The other end of the tension spring 41 is connected to the second bevel gear 42 which is ringed on the fixed bushing 40. A second drive housing 37 is provided on the back plate of the turbine fan 9 at the transmission part of the two sets of bevel gears to cover and isolate its transmission state. Then, by utilizing the support combination of the fixed bushing 40 and the tension spring 41, the second bevel gear 42 has the characteristic of elastic displacement along the fixed bushing 40, so that the second bevel gear 42 and the first bevel gear 39 maintain an elastic meshing state. When the turbine fan 9 is subjected to different water flow impacts and rotates, the rotational force transmitted to the first bevel gear 39 and the second bevel gear 42 maintain a "tooth slippage" driving state, so that all turbine fans 9 apply the same driving force to the drive shaft 13.

[0050] Furthermore, the drive assembly also includes a transmission shaft 12 located on the inner and outer surfaces of the interception and transmission net 8. The transmission shaft 12 is arranged in three sets in a star-delta configuration. One end of the transmission shaft 12 is provided with a transmission worm gear 44, which meshes with a transmission worm 43 located on the drive shaft 13. When the drive shaft 13 rotates, it drives the transmission worm 43 to rotate. By utilizing the meshing transmission between the transmission worm 43 and the transmission worm gear 44, the transmission shaft 12 is driven to rotate, which in turn drives the interception and transmission net 8 to rotate. This allows the interception and transmission net 8 to intercept floating objects on the river surface while simultaneously collecting them through the transmission of the interception and transmission net 8.

[0051] It should be noted that a first drive housing 36 is provided on the outside of the combination of the transmission worm 43 and the transmission worm wheel 44 to enclose and isolate it, and a support bushing 35 is provided along the direction of the transmission shaft 12, with one end fixed to the transmission frame of the intercepting transmission net 8 and the other end fixed to the first drive housing 36. Since the transmission shaft 12 is arranged in a star-triangle configuration on the inner and outer surfaces of the intercepting transmission net 8, it conforms to the characteristic of transmission with an angle of wrapping ≤120° with the intercepting transmission net 8. Furthermore, the combination of the transmission worm 43 and the transmission worm wheel 44 at the bottom of its shaft is designed with opposite driving characteristics, so that… The transmission shaft 12 maintains a suitable direction of rotation to drive the intercepting transmission network 8 (as shown in this embodiment, one set of transmission shafts 12 is placed in the inner belt of the intercepting transmission network 8, and the other two sets of transmission shafts 12 are placed in the outer belt of the intercepting transmission network 8. By setting the corresponding transmission worm 43 and transmission worm wheel 44 in opposite directions, the transmission shafts 12 on the inner and outer belt surfaces of the intercepting transmission network 8 maintain opposite rotations to apply a driving force in the same direction to the intercepting transmission network 8. This can both control the transmission direction of the intercepting transmission network 8 and apply a driving force in the same direction to the intercepting transmission network 8).

[0052] In addition, please see Figures 17-18 To achieve unified collection and treatment of floating debris in the water, floating platforms 7 are set up in pairs facing each other on the water surface. By controlling the transmission direction of the interception and transmission network 8, the interception and transmission network 8 maintains the same transmission direction to intercept and transmit floating debris. A collection net 45 is set up near the shore, facing the side of the interception and transmission network 8 near the shore, to collect the floating debris transmitted from the interception and transmission network 8. Subsequently, staff only need to stand on the shore to complete the daily cleaning of floating debris without entering the water. This makes daily cleaning more convenient and safer, and the collection of floating debris also improves the continuous interception performance of the interception device.

[0053] Please see Figures 6-11 , Figures 17-18To enable the opening and delayed closing of the floating platform 7 during vessel passage, two sets of delay components are configured, arranged in opposite directions. This allows one set of delay components to store power during the rotational opening of the floating platform 7 under the thrust of a vessel, while the other set is unaffected. When vessels pass through the interception device composed of the floating platforms 7, they are controlled to travel smoothly, keeping as close as possible to the center of the two opposing sets of floating platforms 7. The thrust generated by the passing vessels then pushes the opposing sets of floating platforms 7 apart, causing them to open in opposite directions. To provide a passage for vessels, after vessels have passed, by setting the delay components to two sets with opposite delay drives, when the vessels push open the float frame 7 and drive the rotating shaft 24 to rotate, the two sets of delay components acting on the rotating shaft 24 act independently on the rotating shaft 24 in a positive and negative direction. Then, while the rotating shaft 24 maintains unidirectional rotation, one set of delay components stores force for a delay, while the other set is not subjected to force, providing a delayed rotational reset for the rotating shaft 24. This gives the float frame 7 a delayed reset characteristic to avoid the propeller at the stern of the vessel. Specifically:

[0054] The delay assembly includes a first support ring 25 disposed on the delay shell 5, a compression spring 26 disposed above the first support ring 25, a toothed disc 27 disposed at the other end of the compression spring 26, and a second support ring 29 disposed on the rotating shaft 24 away from the toothed disc 27. The edge of the second support ring 29 is provided with a toothed seat 28 that meshes with the toothed disc 27 in a misaligned manner. When the rotating shaft 24 rotates with the float frame 7, it drives the second support ring 29 to rotate, causing the toothed seat 28 at its edge to rotate and move toward the toothed disc 27. The elastic support of the toothed disc 27 by the combination of the first support ring 25 and the compression spring 26 causes the toothed seat 28 to gradually engage with the toothed disc 27 by sliding and pressing down. The frictional resistance between the toothed seat 28 and the toothed disc 27 serves as the delay force for the float frame 7 to reset after opening.

[0055] It should be noted that the teeth of the toothed disc 27 are arranged in a fan-shaped structure, and the tooth grooves of the toothed disc 27 gradually deepen along the rotation direction of the toothed seat 28. By setting the teeth of the toothed disc 27 in a fan-shaped structure, it can provide unloaded displacement space for the toothed seat 28 while simultaneously engaging with it in rotation. Furthermore, by setting the delay components in two opposite sets (as per the instruction manual), Figure 8 , 9 As shown in the figure, while one set of tooth seats 28 rotates and meshes with the tooth disk 27, the rotation of the other set of tooth seats 28 remains unloaded and does not mesh with the tooth disk 27, so that one set of tooth seats stores force for a delay while the other set is not subjected to force. Furthermore, by gradually deepening the tooth grooves of the tooth disk 27 along the rotation direction of the tooth seats 28, the meshing frictional resistance between the tooth seats 28 and the tooth disk 27 gradually increases, so as to provide greater delay resistance.

[0056] As a further embodiment, the delay assembly also includes a fixed sleeve 30 disposed on the delay shell 5 away from the second support ring 29. The fixed sleeve 30 contains multiple sets of guide rings 31. Each guide ring 31 has a stepped arrangement of return springs 32 along its circumference. The other end of each return spring 32 has a pressure block 33. An impact block 34, surrounding the guide rings 31, is disposed on the rotating shaft 24. Driven by the rotation of the rotating shaft 24, the impact block 34 sequentially contacts the pressure block 33. When the rotating shaft 24 rotates with the float frame 7, it drives the impact block 34 to rotate synchronously along the guide ring 31, causing the impact block 34 to sequentially contact the pressure block 33, applying a stepped compressive force to the return spring 32 (the compressive return force of the return spring 32 is greater than the meshing frictional resistance between the toothed seat 28 and the toothed disc 27; by arranging the return springs 32 in multiple stepped sets, the impact block 34...). 4. The return spring 32 is compressed to different degrees to provide a greater return thrust. As the meshing between the toothed seat 28 and the toothed disc 27 gradually deepens, the frictional resistance gradually increases. At this time, the stepwise compression of the return spring 32 by the impact block 34 matches the meshing state of the toothed seat 28 and the toothed disc 27, always providing a return thrust greater than the frictional resistance. When the float frame 7 is reset, the impact block 34 disengages from the return spring 32 one by one, and its return thrust gradually decreases. At the same time, the meshing between the toothed seat 28 and the toothed disc 27 also becomes shallower, so that the rotational reset of the float frame 7 always maintains a stable force for delayed reset, thus providing a greater return thrust to overcome the meshing friction between the toothed seat 28 and the toothed disc 27. This allows the opened float frame 7 to have a delayed rotational reset capability. Furthermore, by setting the delay components to two opposite sets (as per the instruction manual), Figure 10 , 11 As shown), while one set of impact blocks 34 makes a stepped contact with the return spring 32, another set of impact blocks 34 slides unloaded along the guide ring 31 and does not contact the return spring 32, forming a state where one set is compressed and the other is not stressed, in order to overcome the meshing friction between the tooth seat 28 and the tooth disc 27, and serve as the delayed reset force for the float frame 7 after it is opened and reset.

[0057] Please see Figures 1-5To achieve the decompression effect of the floating platform 7 under the thrust of ships during waterway passage, a swing shell 1 is provided below the telescopic frame 4. The swing shell 1 has a support base 14 connected to the telescopic frame 4 in the middle. Support platforms 18 are provided on both sides of the telescopic frame 4. The support platforms 18 are slidably connected to the swing shell 1 via a combination of support guide rails 22 and support slides 23. An arm lever 17 connected to the telescopic frame 4 is provided above the support platform 18, allowing the swing thrust of the telescopic frame 4 to push the support platform 18 to move via a linkage. The bottom of the telescopic frame 4 is provided with… A drive gear 15 is engaged with a driven gear 16 below it. A rack 19 connected to the support platform 18 is engaged below the driven gear 16. This causes the swinging thrust of the telescopic frame 4 to push the support platform 18 to move in a gear-meshing manner. When a vessel pushes away the floating platform 7, the thrust generated is transmitted to the telescopic frame 4. When the floating platform 7 is pushed by the vessel, it causes the telescopic frame 4 to swing around the support base 14. At the same time, the swinging of the telescopic frame 4 drives the drive gear 15 to rotate. The meshing transmission between gear 15 and driven gear 16 transmits the meshing force to rack 19, pushing rack 19 to move in the swing direction of telescopic frame 4, which in turn drives the two sets of support platforms 18 to move. At the same time as the two sets of support platforms 18 move, their displacement also provides rotation space for the two sets of arm levers 17 in the swing direction of telescopic frame 4, so that the two sets of arm levers 17 rotate synchronously under force (the thrust generated by the swing of telescopic frame 4 is transmitted to support platform 18 on the one hand through tooth transmission, and on the other hand through linkage transmission, forming a two-point force transmission method. Moreover, the displacement of support platform 18 through tooth transmission also serves as the rotation displacement space of arm lever 17, so as to improve the displacement consistency of arm lever 17 on both sides when it rotates under force, so that the two sets of different forms of force are transmitted as a whole, which plays a stable support role for telescopic frame 4 and improves the force transmission stability of telescopic frame 4). The thrust generated by the swing of telescopic frame 4 is transmitted to support platform 18 in a two-point force transmission method.

[0058] Furthermore, the upper and lower ends of the support platform 18 are provided with pressure guide rods 20, and the other end of the pressure guide rods 20 is provided with pressure springs 21 to provide displacement reset of the support platform 18. When the support platform 18 is displaced by the swing thrust of the telescopic frame 4, one set of support platforms 18 transmits the displacement force to the pressure springs 21 through the pressure guide rods 20, applying a compressive force to the pressure springs 21, and the other set of support platforms 18 transmits the displacement force to the other set of pressure springs 21 through the pressure guide rods 20, applying a tensile force to the pressure springs 21, so that the support platform 18 has elastic reset characteristics. After the ship passes through and separates from the floating frame 7, the support platform 18 resets under the action of elasticity, pushes the telescopic frame 4 to swing reset, and then drives the floating frame 7 to reset, so as to reduce the collision thrust generated on the floating frame 7 when the ship passes through.

[0059] In addition, by setting a sealing cover 3 connected to the telescopic frame 4 above the swing shell 1, the transmission components that swing and reset with the telescopic frame 4 are sealed to prevent water from entering and affecting the transmission. Furthermore, by setting the sealing cover 3 as a stepped bellows cover structure, it has the telescopic deformation characteristics of swinging and resetting with the telescopic frame 4.

[0060] In addition to the above, a counterweight box 2 is installed on the side of the swing shell 1 near the bottom of the floating frame 7 (the counterweight box 2 is placed near the bottom of the floating frame 7 to avoid overlapping assembly and use space when adjacent floating frames 7 are assembled side by side, resulting in gaps between the floating frames 7). This serves as a support point for the floating frame 7 when it floats. Then, when the whole unit is put into use, a plane is dug in the water beforehand as a support platform for the swing shell 1 and the counterweight box 2. Then, counterweights such as stones and corrosion-resistant metals are filled into the counterweight box 2 to limit and fix the fixed point support of the telescopic frame 4. Then, by adjusting the length of the telescopic frame 4, it is connected to the floating frame 7 floating on the water surface. The floating frames 7 are then horizontally erected on the water surface in pairs and float. The upper half of the floating frame 7 is used to support the floating frame 7. The interception and transmission net 8 intercepts and collects floating debris in the water. Its opposing opening and closing between the two sets of floating frames 7 not only provides a passage for passing ships (because the floating frames 7 have an interception and transmission net 8 that collects and transmits the intercepted floating debris, the floating debris is concentrated in the collection net 45 under the transmission action, and the floating debris does not accumulate on the floating frames 7, so that a large amount of floating debris is not lost when ships pass), but also has a deflection opening and pressure reduction function. When the water flow suddenly becomes rapid due to the release of water during the rainy season, the water flow can push the floating frames 7 to swing towards the direction of the water flow, so as to reduce its lateral impact force and avoid the floating frames 7 from collapsing under strong water flow, thereby improving the self-protection capability of the interception device.
