Description

Technical Field

[0001] This application relates to the field of river ecological restoration, and particularly to a river ecological restoration device and a restoration method. Background Art

[0002] Floating garbage on the river surface is usually one of the important reasons for the destruction of the river ecosystem. The existence of floating garbage not only pollutes the river water quality, but also has a serious impact on the aquatic animals and plants in the river. Therefore, the cleaning of floating garbage on the river surface has become an important link in promoting river ecological restoration.

[0003] Currently, the floating garbage on the river surface is mainly cleaned by manual salvage. Specifically, the operator drives a small boat to move forward in the river and uses equipment such as a scoop net to complete the salvage operation of the floating garbage.

[0004] Regarding the above related technologies, the above-mentioned operation method of manually salvaging floating garbage not only requires a large amount of manpower, but also has a low operation efficiency. Therefore, there is room for improvement. Summary of the Invention In order to facilitate the better salvage and cleaning of floating garbage on the river surface, this application provides a river ecological restoration device and a restoration method.

[0005] A river ecological restoration device and a restoration method provided by this application adopt the following technical solutions: A river ecological restoration device includes a hull, and a collection component and a driving component are arranged on the hull; The hull includes two relatively arranged floating barrels, and the two floating barrels are connected and fixed by a connecting bracket; The collection component includes a collection net box, the collection net box is supported between the two floating barrels, and the side of the collection net box facing the front end of the hull is provided with an opening to form an opening side; The driving component includes two first screw propellers, and the two first screw propellers are respectively installed at the tail ends of the two floating barrels.

[0006] By adopting the above technical solutions, when cleaning the floating garbage on the river surface, the first screw propellers at the tail ends of the two floating barrels cooperate to drive the hull to move forward on the water surface. During the movement of the hull, the floating garbage on the river surface is intercepted and collected by the collection net box between the two floating barrels. Subsequently, after the hull returns to shore, the garbage in the collection net box is removed, realizing the automatic cleaning of the floating garbage in the river. Compared with the traditional method of manually salvaging floating garbage, the overall cleaning difficulty is reduced, and the cleaning efficiency of the floating garbage on the river surface is effectively improved.

[0007] Preferably, support plates are protruding from the tops of opposite sides of the collecting net box, and the support plates on opposite sides of the collecting net box are respectively erected on the tops of two buoys, and the buoys are provided with limiting parts corresponding to the support plates, and the limiting parts are used to limit the support plates from sliding along the buoys.

[0008] By adopting the above technical scheme, by protruding support plates on the opposite sides of the collecting cage, the collecting cage is erected between two buoys using the two support plates. When cleaning the garbage in the collecting cage later, the collecting cage can be taken out from between the two buoys to facilitate the cleaning operation of the garbage in the collecting cage; by setting the limiting part, the limiting part can be used to limit the movement of the support plate along the buoy during the subsequent movement of the hull, so as to limit the slippage of the collecting cage between the two buoys, which is conducive to more firmly supporting the collecting cage between the two buoys.

[0009] Preferably, the limiting portion includes two limiting protrusions protruding from the top of the buoy, and the support plate is embedded between the two limiting protrusions.

[0010] By adopting the above technical solution, the support plate is limited by two limiting protrusions to prevent the support plate from sliding along the buoy. At the same time, when the collecting box is installed between the two buoys, the support plate can be assisted in positioning by the two limiting protrusions, so as to facilitate the rapid installation of the collecting box.

[0011] Preferably, the driving assembly further comprises a second screw propeller, the second screw propeller is located between the two buoys, and the second screw propeller is arranged opposite to a side of the collecting net box which is away from the opening side thereof.

[0012] By adopting the above technical scheme, on the one hand, the second screw propeller can assist the two first screw propellers to drive the hull forward; on the other hand, when the garbage on the water surface is relatively scattered, the first screw propeller and the second screw propeller can cooperate to make the hull be in a hovering state, and at the same time, the second screw propeller can cooperate with the two buoys to form a guide water flow from the bow to the stern between the two buoys, and the formed guide water flow can be used to gather the garbage around the front end of the hull to the front end of the hull, so as to facilitate the subsequent collection cage to better intercept and collect the surface garbage.

[0013] Preferably, a sealing assembly is also provided at the front end of the hull, and the sealing assembly includes a sealing bracket, and the sealing bracket supports a sealing mesh plate, and the sealing mesh plate blocks the opening side of the collecting box. The sealing bracket is also provided with a lifting drive member for driving the sealing mesh plate to rise and fall vertically.

[0014] By adopting the above technical solution, before the first screw propeller and the second screw propeller cooperate to drive the hull to move backward on a narrow river channel, the lifting drive member is used to drive the sealing net plate to move downward and block the opening side of the collection net box, so as to reduce the water flow generated by the second screw propeller, which may cause the garbage in the collection net box to be washed out of the collection net box. At the same time, when the collection net box is taken out from between the two floating barrels later, the lifting drive is first used to drive the sealing net plate to move downward and block the opening side of the collection net box, so as to limit the situation that the garbage in the collection net box floats out from its opening side during the process of lifting the collection net box.

[0015] Preferably, intercepting net plates are connected to the front ends of the floating barrels, and the intercepting net plates of the two floating barrels are arranged in a flared shape.

[0016] By adopting the above technical solution, the two intercepting net plates cooperate with each other to form a flared shape, which is beneficial to increasing the interception range of the hull for the floating garbage on the water surface. At the same time, the water flow at the bow of the hull can be diverted to between the two floating barrels through the two intercepting net plates, facilitating the collection net box between the two floating barrels to better intercept and collect the garbage. When using the mesh structure of the intercepting net plate itself, it is beneficial to reduce the resistance of the ship during the traveling process.

[0017] Preferably, rotating supports are arranged at the front ends of the floating barrels corresponding to the intercepting net plates. One end of the intercepting net plate close to the floating barrel is vertically rotatably connected to the rotating support through a connecting shaft. A rotary drive member is arranged on the rotating support, and the rotary drive member is drivingly connected to the connecting shaft at the end of the rotating support. The rotary drive member is used to drive the connecting shaft to rotate.

[0018] By adopting the above technical solution, the rotary drive member is used to drive the end of the intercepting net plate to rotate around the connecting shaft. On the one hand, the flaring degree of the two intercepting net plates can be adjusted according to the actual interception needs. On the other hand, during the process of the hull traveling on the narrow water surface, the two intercepting net plates can be swung towards each other to realize the storage of the two intercepting net plates, reducing the situation of collision and damage of the two flared intercepting net plates.

[0019] A restoration method for river ecological restoration, using the above river ecological restoration equipment, includes the following steps: S1: Equipment positioning: Place the hull in the river channel; S2: Floating garbage cleaning: The driving component drives the hull to drive the collection net box to travel on the water surface to be cleaned, and the collection net box on the hull intercepts and cleans the floating garbage on the water surface; S3: Equipment recovery: The driving component drives the hull to drive the collection net box and the intercepted and cleaned garbage to return to the shore; S4: Garbage cleaning: Clean the floating garbage intercepted by the collection net box.

[0020] By adopting the above technical solution, the floating garbage in the river is intercepted and processed through the movement of the hull in cooperation with the collection net box on the hull. Compared with the traditional manual cleaning method, the cleaning efficiency of the floating garbage on the river surface is effectively improved.

[0021] In summary, the present application includes at least one of the following beneficial technical effects: 1. During the process of the hull advancing on the water surface through the driving component, the collection net box between the two floating barrels drives the garbage on the river surface, realizing the automatic cleaning of the garbage on the river surface, effectively reducing the cleaning difficulty of the garbage on the river surface, and improving the overall cleaning efficiency.

[0022] 2. Through the setting of the second screw propeller, on the one hand, it can cooperate with the first screw propeller to drive the hull to advance on the water surface together. On the other hand, during the actual cleaning process, after the hull is in a hovering state by the cooperation of the first screw propeller and the second screw propeller, the second screw propeller cooperates with the two floating barrels to form a guiding water flow between the two floating barrels, so as to gather the garbage around the front end of the hull to the front end of the hull, facilitating the subsequent interception of the garbage by the collection net box.

[0023] 3. Through the setting of the sealing component at the front end of the hull, when the hull is driven backward by the second screw propeller, the lifting driving member of the sealing component is used to drive the sealing net plate to move downward to block the opening side of the collection net box, so as to limit the garbage in the collection net box from flowing out from the opening side of the collection net box during the process of the hull moving backward.

[0031] The following will Figures 1-6 make a further detailed description of this application in conjunction with the attached drawings.

[0032] An embodiment of this application discloses a river ecological restoration device and a restoration method. Refer to Figure 1 and Figure 2 , including a hull, on which a collection component and a drive component are arranged. The hull includes two oppositely arranged buoys 1, which are connected by a connection bracket 11 and there is a gap between the two buoys 1. The collection component includes a collection net box 2; the collection net box 2 is supported between the two buoys 1, and the side of the collection net box 2 facing the front end of the hull is open to form an open side 20. The drive component is located at the rear end of the hull, and the drive component includes two first screw propellers 3 and one second screw propeller 4 installed on the connection bracket 11; the two first screw propellers 3 are respectively located at the rear ends of the two buoys 1; the second screw propeller 4 is located between the two buoys 1.

[0033] The first screw propeller 3 and the second screw propeller 4 are used to drive the hull to move forward on the water surface. During the movement of the hull, the floating garbage on the river surface is intercepted and collected by the collection net box 2 between the two buoys 1, realizing the automatic cleaning of the floating garbage on the river surface.

[0034] Intercepting net plates 5 are supported at the front ends of the two buoys 1, and the intercepting net plates 5 extend in a direction away from the buoys 1. The intercepting net plates 5 at the front ends of the two buoys 1 are arranged in a flared shape in cooperation. During the subsequent movement of the hull, the intercepting net plates 5 at the front ends of the two buoys 1 are used to intercept and gather the garbage near the front end of the hull and divert it between the two buoys 1, so that the subsequent collection net box 2 can better intercept and collect it.

[0035] The front end of the buoy 1 is provided with a rotating support 52 corresponding to the interception net plate 5; the end of the interception net plate 5 close to the buoy 1 is fixed with a connecting shaft 51, which is arranged vertically, and the two ends of the connecting shaft 51 are rotatably connected to the rotating support 52 through bearings. The support is provided with a rotary drive member 53 for driving the connecting shaft 51 to rotate, corresponding to the connecting shaft 51, and the rotary drive member 53 includes a reduction motor installed on the rotating support 52, and the output end of the reduction motor is connected to the end of the connecting shaft 51 through a coupling, so that the rotary drive member 53 is driven to connect to the connecting shaft 51. Through the above arrangement, the rotary drive member 53 is used to drive the connecting shaft 51 to drive the interception net plate 5 to rotate, so that the expansion degree of the two interception net plates 5 can be adjusted. When the hull is traveling in narrow waters, the corresponding connecting shafts 51 can be driven by the rotary drive members 53 on the two buoys 1 to drive the interception net plates 5 to swing in the direction of approaching each other, so as to reduce the expansion degree of the two interception net plates 5, thereby reducing the situation of scratching and damage to the interception net plates 5 during the travel of the hull.

[0036] A plurality of flexible buffers 10 are installed on the sides of the two buoys 1 facing away from each other. In the present embodiment, the flexible buffers 10 are discarded tires. The provision of the flexible buffers 10 is beneficial to reducing the possibility of the buoys 1 being damaged due to collisions with both sides of the river when the ship is sailing in a narrow river.

[0037] Reference Figure 3 and Figure 4 The top of the collecting net box 2 near the buoy 1 is provided with a support plate 21 protruding outwards, and the support plate 21 is welded to the collecting net box 2. The support plates 21 on the opposite sides of the collecting net box 2 are respectively overlapped on the tops of the two buoys 1, so that the collecting net box 2 is set up between the two buoys 1. When cleaning the garbage intercepted inside the collecting net box 2 later, the collecting net box 2 can be lifted upward from between the two collecting net boxes 2 to facilitate the cleaning of the garbage inside the collecting net box 2. A number of handles 22 are also welded on the support plate 21, so that the collecting net box 2 can be moved by the handles 22.

[0038] The buoy 1 is provided with a limiting portion corresponding to the support plate 21 for limiting the sliding of the support plate 21 along the length direction of the buoy 1. The limiting portion includes two limiting protrusions 12 protruding from the top of the buoy 1. The two limiting protrusions 12 are respectively located at both ends of the support plate 21. The support plate 21 is embedded between the two limiting protrusions 12 and the two ends of the support plate 21 are respectively abutted against the opposite sides of the two limiting protrusions 12. The two limiting protrusions 12 are used to limit the support plate 21 to limit the subsequent movement of the collecting box 2 along the buoy 1 through the support plate 21 during the movement of the hull, which is conducive to the more stable installation of the collecting box 2 between the two buoys 1. At the same time, when the collecting box 2 is subsequently installed between the two buoys 1, the limiting protrusion 12 can be used as a positioning reference for the support plate 21, so as to facilitate the rapid installation of the support plate 21.

[0039] ReferenceFigure 1 and Figure 5 The bottom of the collecting net box 2 is set lower than the bottom of the buoy 1, so that the subsequent collecting net box 2 can better intercept and collect the garbage and debris immersed in the water.

[0040] Reference Figure 5 and Figure 6 , the propulsion directions of both the first screw propeller 3 and the second screw propeller 4 are arranged parallel to the length of the hull. The second screw propeller 4 is located on the side of the collection net box 2 away from the opening side 20 thereof and the second screw propeller 4 is arranged opposite to the collection net box 2. Through the arrangement of the second screw propeller 4, on the one hand, the second screw propeller 4 can be used to cooperate with the first screw propeller 3 at the tail end of the two buoys 1 to drive the hull forward. On the other hand, when the garbage on the water surface is relatively scattered, the two first screw propellers 3 can be used to cooperate with the second screw propeller 4 to temporarily suspend the hull on the water surface, specifically, the first screw propeller 3 pushes water forward and the second screw propeller 4 pushes water backward to achieve temporary suspension of the hull; at the same time, the second screw propeller 4 cooperates with the two buoys 1 of the hull to form a guide water flow from the front end of the hull to the tail end of the hull between the two buoys 1 of the hull, and the guide water flow is used to gather the garbage near the front end of the hull toward the front end of the hull, which is conducive to the subsequent hull to be better intercepted and collected by the collection net box 2.

[0041] A sealing assembly 6 is also provided at the front end of the hull, and the sealing assembly 6 includes a sealing bracket 61, a sealing mesh plate 62 and a lifting drive 63. The two ends of the sealing bracket 61 are respectively fixed to the tops of the two buoys 1, so that the sealing bracket 61 can be stably supported at the front end of the hull, and the connection integrity between the two buoys 1 can be improved through the sealing bracket 61. The sealing mesh plate 62 blocks the opening side 20 of the collection box 2, and the lifting drive 63 is installed on the sealing bracket 61 and the lifting drive 63 is connected to the sealing mesh plate 62 for driving the sealing mesh plate 62 to lift and lower it vertically.

[0042] Specifically, the lifting drive member 63 includes two lifting cylinders, which are installed on the top of the sealing bracket 61 and are vertically arranged downward. The bottom ends of the piston rods of the two lifting cylinders are connected to the top of the sealing mesh plate 62 to realize the driving connection between the lifting drive member 63 and the sealing mesh plate 62.

[0043] With the provision of the sealing assembly 6, when the hull then drives the collection cage 2 to intercept and collect floating garbage on the river surface, the lifting drive member 63 drives the sealing net plate 62 to move upward, so that the opening side 20 of the collection cage 2 is opened, facilitating the collection cage 2 to intercept and collect garbage; before the hull travels backward through the first screw propeller 3 and the second screw propeller 4 on a narrow river, the lifting drive member 63 drives the sealing net plate 62 to move downward, such that the sealing net plate 62 blocks the opening side 20 of the collection cage 2, to limit the situation where the garbage in the collection cage 2 flows out through the opening side 20 when the hull subsequently travels backward under the cooperation of the first screw propeller 3 and the second screw propeller 4. Meanwhile, before the collection cage 2 is lifted from between the two pontoons 1 subsequently, the lifting drive member 63 can also be driven to move downward, so that the sealing net plate 62 blocks the opening side 20 of the collection cage 2, restricting the situation where the internal garbage of the collection cage 2 falls out from the opening side 20 during the upward movement.

[0044] A restoration method for river ecological restoration, using the above-mentioned river ecological restoration equipment, referring to Figure 5 and Figure 6 , includes the following steps: S1: Equipment positioning: Place the hull on the river surface; S2: Floating garbage cleaning: The first screw propeller 3 at the rear end of the hull cooperates with the second screw propeller 4 to drive the hull to drive the collection cage 2 to travel on the water surface to be cleaned. During the hull's travel, the collection cage 2 located between the two pontoons 1 of the hull intercepts and collects the floating garbage on the water surface; S3: Equipment recovery: The first screw propeller 3 at the rear end of the hull cooperates with the second screw propeller 4 to drive the hull to drive the collection cage 2 and the intercepted and cleaned garbage to return to the shore; S4: Garbage cleaning: S4.1: Sealing the opening side 20 of the collection cage 2: The lifting drive member 63 on the sealing support 61 drives the sealing net plate 62 to move downward, so that the sealing net plate 62 blocks the opening side 20 of the collection cage 2; S4.2: Lift the collection cage 2 upward from between the two pontoons 1; clean the floating garbage intercepted by the collection cage 2.

[0045] This application utilizes the hull to cooperate with the collection assembly and the drive assembly on the hull to achieve automatic interception and cleaning of the floating garbage on the river surface, effectively improving the cleaning efficiency of the river floating garbage.

[0046] The above are all the preferred embodiments of this application. Without restricting the protection scope of this application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
