[0046] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0047] In related technologies, to maintain the aquatic environment of surface water, a cleaning device is typically towed by a vessel to move across the water surface and collect floating debris. This cleaning device includes components such as a net suitable for capturing and intercepting floating debris. However, in practical applications, the position and orientation of the cleaning device during use are limited by the movement of the vessel. Consequently, without a driving mechanism such as a vessel, the net is difficult to maintain on the water surface and in a direction facing the current, making it difficult to capture and intercept floating debris. Furthermore, this cleaning method requires operators to spend extended periods driving the vessel, resulting in relatively high vessel and labor costs, which is detrimental to controlling the cost of maintaining the aquatic environment.

[0048] In view of this, such as Figures 1 to 4 As shown in the present disclosure, a device for collecting floating debris on the water surface of a hydropower plant reservoir is proposed, comprising: a fixing component 100, one end of which is set on the riverbed and the other end is arranged close to the water surface; a collection component 200, which is set on the water surface, having an inlet end 201, a outlet end 202, and a collection chamber 203, the collection chamber 203 being connected between the inlet end 201 and the outlet end 202, the collection component 200 being connected to the fixing component 100, and the inlet end 201 and the outlet end 202 being arranged along the water flow direction in the riverbed; and a filter element 400, which is disposed on the outlet end 202.

[0049] The floating debris collection device for a hydropower plant reservoir area provided in this embodiment includes the aforementioned fixing component 100, collection component 200, and filter element 400. In practical applications, the aforementioned floating debris collection device can be arranged in the water area of ​​a hydropower plant reservoir. The aforementioned collection component 200 has an inlet end 201, an outlet end 202, and a collection cavity 203 connecting the aforementioned inlet end 201 and the aforementioned outlet end 202. The aforementioned filter element 400 is disposed at the aforementioned outlet end 202. Therefore, in practical applications, when water flows into the collection cavity 203 through the aforementioned inlet end 201 and flows out through the aforementioned outlet end 202, the aforementioned floating debris collection device can use the aforementioned filter element 400 to intercept at least a portion of the solid matter carried by the water flow, so that the solid matter is retained in the aforementioned collection cavity 203, thereby achieving water filtration. One end of the aforementioned fixing component 100 can be set on the riverbed of the aforementioned reservoir area, and the other end can be arranged close to the water surface of the aforementioned riverbed. The aforementioned collection component 200 is set on the fixing component 100 and is arranged on the water surface of the aforementioned riverbed. Thus, the aforementioned floating object collection device can use the fixing component 100 to fix and support the collection component 200, so that the position of the collection component 200 is kept on the aforementioned water surface. This facilitates the collection component 200 to access the surface water of the aforementioned reservoir area, which can increase the probability of the aforementioned surface water flowing into the aforementioned collection chamber 203. This is beneficial to improve the collection efficiency of the aforementioned collection component 200 in collecting solid floating objects in the aforementioned surface water, reduce the need for drive equipment and manual intervention during the use of the aforementioned floating object collection device, and thus save the use cost of the aforementioned floating object collection device and reduce the maintenance cost of the water environment of the aforementioned reservoir area.

[0050] It should be noted that, Figure 1 The dashed lines X1, X2, and X3 are used to represent three different directions. The dashed lines X1, X2, and X3 are perpendicular to each other. Among them, the dashed line X2 is used to schematically represent the arrangement direction of the aforementioned liquid inlet end 201 and the aforementioned liquid outlet end 202.

[0051] Understandably, in practical applications, both ends of the aforementioned fixing component 100 can be arranged along the depth direction of the aforementioned riverbed. Correspondingly, one end of the aforementioned fixing component 100 can be fixedly set at the bottom of the aforementioned riverbed, and the other end can be arranged close to the aforementioned water surface, thereby improving the stability of the fixing component 100 and helping to ensure that the collecting component 200 is at the aforementioned water surface. Accordingly, the distance between the two ends of the fixing component 100 can be set in conjunction with the depth of the riverbed, and no further limitations are imposed here.

[0052] It is understood that the aforementioned collection component 200 being set on the water surface means that the collection component 200 intersects with the aforementioned water surface and at least part of the liquid inlet end 201 is submerged below the water surface, thereby facilitating the aforementioned liquid inlet end 201 to access the aforementioned surface water flow.

[0053] It is understood that the aforementioned inlet end 201 and outlet end 202 are arranged along the direction of water flow in the riverbed. This means that in actual application, the arrangement direction of the aforementioned inlet end 201 and outlet end 202 can be roughly parallel to the direction of water flow in the aforementioned riverbed, and the inlet end 201 is located upstream of the outlet end 202.

[0054] It is understood that both the aforementioned inlet end 201 and the aforementioned outlet end 202 are open ends, and the aforementioned filter element 400 covers the aforementioned outlet end 202. In practical applications, the conduction direction of the inlet end 201 and the conduction direction of the outlet end 202 can both be consistent with the arrangement direction of the aforementioned inlet end 201 and outlet end 202, and the inlet end 201 and outlet end 202 can be arranged coaxially, which helps to reduce the flow resistance of the collection component 200 and facilitates more efficient water flow through the collection component 200.

[0055] Understandably, in practical applications, if the riverbed is wide, multiple of the aforementioned floating debris collection devices can be arranged along the width of the riverbed, thereby increasing the interception rate of floating debris on the water surface and improving the protection of the aquatic environment.

[0056] It is understood that the aforementioned floating objects can be, but are not limited to, solid floating objects such as plastic bags, packaging bottles, and leaves.

[0057] It is understood that the aforementioned filter element 400 can be, but is not limited to, a filter screen, a filter bag, etc., and is suitable for intercepting at least part of the solid matter carried by the water flow when the water flows through it; the filtration accuracy of the aforementioned filter element 400 can be set according to actual needs, and no further limitations are made here.

[0058] like Figure 1 and Figure 2 As shown, in some examples, the floating debris collection device in the reservoir area of ​​a hydropower plant further includes: a guide component 300 disposed on the collection component 200, the collection component 200 being rotatably connected to the fixing component 100, the inlet end 201 and the outlet end 202 being arranged radially along the rotation axis of the collection component 200, and the guide component 300 being used to drive the collection component 200 to rotate under the drive of the water flow, so that the inlet end 201 and the outlet end 202 are arranged along the direction of the water flow.

[0059] In this technical solution, the arrangement direction of the aforementioned inlet end 201 and the aforementioned outlet end 202 is consistent with a radial direction of the rotation axis of the collecting component 200, thereby allowing the collecting component 200 to have a certain degree of freedom of movement, so as to flexibly adjust the orientation of the inlet end 201 of the collecting component 200. Correspondingly, the aforementioned floating object collecting device may also include the aforementioned guide component 300, which is disposed on the aforementioned collecting component 200 and configured to drive the collecting component 200 to rotate under the drive of water flow, so that the aforementioned inlet end 201 and outlet end 202 are arranged along the water flow direction and the aforementioned The inlet end 201 is located upstream of the outlet end 202, so the collection component 200 can adapt to the flow direction of the surface water during use, and more stably and reliably access the surface water through the inlet end 201 to intercept the solid floating objects carried by the surface water, thereby improving the collection efficiency of the floating object collection device for solid floating objects. It can also reduce the adjustment of the orientation of the collection component 200 by the operators when the water flow direction in the riverbed changes, which is conducive to further reducing the use cost of the floating object collection device and improving the ease of use of the floating object collection device.

[0060] It should be noted that, Figure 1 The dashed line X1 is used to schematically indicate the direction of extension of the rotation axis of the aforementioned collection component 200.

[0061] It is understandable that, in practical applications, the rotation axis of the aforementioned collection component 200 can be arranged along the depth direction of the aforementioned riverbed, so that the radial direction of the aforementioned rotation axis is approximately parallel to the water surface. Correspondingly, the arrangement direction of the aforementioned liquid inlet end 201 and the aforementioned liquid outlet end 202 can also be approximately parallel to the water surface. Thus, when the collection component 200 is driven to rotate by the guide component 300, it is convenient for the arrangement direction of the aforementioned liquid inlet end 201 and the aforementioned liquid outlet end 202 to conform to the aforementioned water flow direction.

[0062] It is understood that, based on the aforementioned configuration, the aforementioned collecting component 200 and the aforementioned guiding component 300 can be constructed as a flow vane structure, that is, the collecting component 200 can have a working position in the rotation direction. When the collecting component 200 is in the aforementioned working position, the liquid inlet end 201 and the liquid outlet end 202 are arranged along the water flow direction and the liquid inlet end 201 is located upstream of the liquid outlet end 202. Furthermore, when the collecting component 200 is in the aforementioned working position, the resistance generated by the collecting component 200 and the aforementioned guiding component 300 to the water flow is minimized, thereby allowing the aforementioned collecting component 200 and the aforementioned guiding component 300 to rotate to the aforementioned working position under the drive of the water flow. Accordingly, the aforementioned guide component 300 can be arranged around the aforementioned rotation axis, and the outer wall surface of the guide component 300 at different positions in the circumferential direction of the aforementioned rotation axis can form different shapes, so that the flow resistance generated by the outer wall surface at the aforementioned different positions when facing the water flow is different, and the flow resistance is minimal when the collecting component 200 is in the aforementioned working position, thereby facilitating the guide component 300 to drive the collecting component 200 to rotate under the drive of the water flow, so that the collecting component 200 is in the aforementioned working position.

[0063] It is understandable that, in practical applications, at least a portion of the guide component 300 is used to be submerged below the aforementioned water surface so that the guide component 300 is driven by the water flow.

[0064] like Figure 1 and Figure 2 As shown, in some examples, the fixing assembly 100 includes: a fixing fork 110 for insertion into the riverbed; a connecting rod 120 having a first connecting end and a second connecting end, the first connecting end being connected to the fixing fork 110 and the second connecting end being arranged close to the water surface; and a bearing 130, the inner ring of which is fixedly sleeved on the second connecting end and the outer ring of which is fixedly disposed on the collecting assembly 200.

[0065] In this technical solution, the fixing component 100 may include the aforementioned fixing fork 110, the aforementioned connecting rod 120, and the aforementioned bearing 130. Based on the aforementioned configuration, the fixing component 100 can be inserted into the riverbed through the aforementioned fixing fork 110 to ensure positional stability and reliability during use. This facilitates the fixing component 100 to provide stable structural support for the collection component 200, thereby allowing the collection component 200 to be positioned on the aforementioned water surface. One end of the connecting rod 120 is connected to the aforementioned fixing fork 110, and the other end is rotatably connected to the collection component 200 through the bearing 130, thereby giving the collection component 200 rotational freedom and supporting the collection component 200 on the water surface.

[0066] It is understandable that, such as Figure 1 and Figure 2As shown, the fixing fork 110 can have multiple conical structures, which can be inserted into the silt at the bottom of the riverbed in practical applications. Exemplarily, the conical structures can also be provided with barbs, thereby improving the fixing fork 110's gripping force on the riverbed, enhancing its resistance to upward pulling forces and overturning moments, and strengthening the stability of the aforementioned floating debris collection device in practical applications.

[0067] It is understandable that in this technical solution, Figure 1 The dotted line X1 in the diagram can also be used to schematically represent the axial direction of the aforementioned connecting rod 120 and the aforementioned bearing 130.

[0068] In some examples, the connecting rod 120 is a telescopic structure, allowing the distance between the collecting assembly 200 and the fixed fork 110 to be adjustable.

[0069] In this technical solution, the connecting rod 120 can be a telescopic structure, allowing the distance between the collecting component 200 and the fixed fork 110 to be adjustable. Based on this configuration, when the fixed fork 110 is inserted into the riverbed, the connecting rod 120 can adjust the distance between the collecting component 200 and the fixed fork 110 by telescopic deformation. This allows operators to adjust the position of the collecting component 200 according to the depth of the water flow in the riverbed, positioning the collecting component 200 at the water surface. This increases the probability of surface water flowing into the collecting chamber 203, improving the collection efficiency of the collecting component 200 in collecting solid floating objects from the surface water and enhancing the ease of use of the floating object collection device.

[0070] like Figure 3 and Figure 4 As shown, in some examples, the connecting rod 120 includes: a sleeve 121, one end of which is configured as a first connecting end; an extension rod 122 slidably passing through the sleeve 121, the end of the extension rod 122 away from the first connecting end being configured as a second connecting end; and a limiting member 123 for limiting the sliding of the extension rod 122 relative to the sleeve 121.

[0071] In this technical solution, the connecting rod 120 may include the aforementioned sleeve 121, the aforementioned extension rod 122, and the aforementioned limiting member 123. Based on the aforementioned configuration, during the sliding process along the aforementioned sleeve 121, the extension rod 122 can extend or retract into the sleeve 121 through the end of the aforementioned sleeve 121 away from the aforementioned first connecting end, thereby realizing the length adjustment of the connecting rod 120. The aforementioned limiting member 123 can be used to restrict or release the relative sliding between the extension rod 122 and the sleeve 121. Thus, when the length adjustment of the connecting rod 120 is required, the operator can release the restriction of the relative sliding between the sleeve 121 and the extension rod 122 by operating the limiting member 123, so as to facilitate the extension and retraction of the connecting rod 120. After the length of the connecting rod 120 is adjusted to the correct position, the limiting member 123 can be operated to restrict the relative sliding between the sleeve 121 and the extension rod 122, so as to ensure the length stability of the connecting rod 120, thereby providing a guarantee for the positional stability of the collection assembly 200.

[0072] For example, the inner peripheral wall of the sleeve 121 and the outer peripheral wall of the extension rod 122 are both provided with anti-rust coating, thereby reducing the risk of water erosion on the inner peripheral wall of the sleeve 121 and the outer peripheral wall of the extension rod 122, which helps to avoid jamming of the extension rod 122 during sliding and extends the service life of the connecting rod 120.

[0073] For example, the aforementioned anti-rust coating may be, but is not limited to, a hot-dip galvanized layer.

[0074] For example, the sleeve 121 and the extension rod 122 are detachably connected, which facilitates the cleaning and maintenance of the inside of the sleeve 121 and the extension rod 122, helps to ensure the cleanliness of the inside of the connecting rod 120, and thus ensures the telescopic stability of the connecting rod 120.

[0075] like Figure 3 and Figure 4 As shown, in some examples, the limiting member 123 includes: a limiting pin 123a; a sleeve 121 having a first connecting hole 1211 that is radially open along the sleeve 121; an extension rod 122 having a second connecting hole 1221 that is radially open along the extension rod 122; the limiting pin 123a being detachably inserted through the first connecting hole 1211 and the second connecting hole 1221; and a limiting clamp 123b detachably disposed on the limiting pin 123a, the limiting clamp 123b being used to limit the axial sliding of the limiting pin 123a along the first connecting hole 1211 and / or the second connecting hole 1221; wherein, there are multiple first connecting holes 1211, and the multiple first connecting holes 1211 are arranged at intervals along the axial direction of the sleeve 121.

[0076] In this technical solution, the limiting member 123 may include the aforementioned limiting pin 123a and the aforementioned limiting clamp 123b. Based on the aforementioned configuration, during the sliding of the extension rod 122 along the sleeve 121, the second connecting hole 1221 can correspond to the first connecting hole 1211 at different positions along the axial direction of the sleeve 121. Correspondingly, when the limiting pin 123a passes through one of the multiple first connecting holes 1211 and the aforementioned second connecting hole 1221, the relative sliding between the sleeve 121 and the extension rod 122 can be restricted, thereby improving the length stability of the connecting rod 120. When the limiting pin 123a passes through one of the multiple first connecting holes 1211 and the aforementioned second connecting hole 1221, and the limiting clamp 123b is disposed on the limiting pin 123a, the axial sliding of the limiting pin 123a along the first connecting hole 1211 and / or the second connecting hole 1221 can also be restricted, thereby preventing the limiting pin 123a from loosening and improving the reliability of the limiting member 123 in restricting the relative sliding between the sleeve 121 and the extension rod 122.

[0077] It is understandable that, such as Figure 3 As shown, when the limiting pin 123a is inserted into one of the multiple first connecting holes 1211 and the aforementioned second connecting hole 1221, both ends of the limiting pin 123a can be located outside the sleeve 121. The number of the aforementioned limiting clips 123b can be two, and the two limiting clips 123b are respectively engaged with both ends of the limiting pin 123a, thereby improving the movement constraint effect of the limiting clips 123b on the limiting pin 123a and reducing the risk of the limiting pin 123a becoming loose.

[0078] like Figure 1 and Figure 2 As shown, in some examples, the collection assembly 200 includes: a storage tank 210 having an inlet end 201, a drain end 202, and a collection chamber 203; a magnetic ring 220, one side of which is magnetically attracted to the storage tank 210 and arranged around the drain end 202; and a filter element 400 magnetically attracted to the other side of the magnetic ring 220 and covering the drain end 202.

[0079] In this technical solution, the collection component 200 may include the aforementioned storage tank 210 and the aforementioned magnetic ring 220. Based on the aforementioned configuration, the collection component 200 can use the storage tank 210 to contain the aforementioned solid floating matter, so as to facilitate the centralized collection of solid floating matter. Furthermore, the drain end 202 of the storage tank 210 can be magnetically connected to the aforementioned filter element 400 through the magnetic ring 220, thereby ensuring the installation stability of the filter element 400, facilitating the disassembly and replacement of the filter element 400, and making it easier to open the aforementioned drain end 202 to improve the cleaning convenience inside the collection chamber 203.

[0080] It is understood that the aforementioned magnetic ring 220 can be made of permanent magnet material, and the aforementioned storage tank 210 and the aforementioned filter element 400 can be made of ferromagnetic material.

[0081] It is understandable that the magnetic strength of the aforementioned magnetic ring 220 can be set according to actual needs, and no further restrictions are imposed here.

[0082] like Figure 1 and Figure 2 As shown, in some examples, the collecting component 200 further includes: a tapered tube 230, the two ends of which in the axial direction are a first liquid-passing end 2301 and a second liquid-passing end 2302, respectively, the conducting area of ​​the first liquid-passing end 2301 being larger than the conducting area of ​​the second liquid-passing end 2302; and a connecting tube 240, which is connected between the second liquid-passing end 2302 and the liquid-inlet end 201, and the connecting tube 240 is a telescopic structure.

[0083] In this technical solution, the collection component 200 may further include the aforementioned tapered tube 230 and the aforementioned connecting tube 240. Based on the aforementioned configuration, the collection component 200 can, on the one hand, expand the water collection range using the aforementioned tapered tube 230, which is beneficial to increasing the water flow rate of the collection component 200 during use, thereby improving the efficiency of handling floating objects; on the other hand, when the water level in the aforementioned riverbed fluctuates, the expansion and contraction properties of the connecting tube 240 can be used to compensate for the position between the aforementioned tapered tube 230 and the aforementioned storage tank 210, so as to avoid structural damage to the collection component 200 under the action of water level fluctuations, which is beneficial to extending the service life of the collection component 200.

[0084] For example, the two ends of the connecting pipe 240 may be formed with internal threads, the second liquid passage end 2302 and the liquid inlet end 201 may be formed with external threads, and the two ends of the connecting pipe 240 are respectively connected to the aforementioned second liquid passage end 2302 and the aforementioned liquid inlet end 201 with sealing threads.

[0085] For example, the connecting pipe 240 can be a bellows.

[0086] like Figure 1 and Figure 2 As shown, in some examples, along the arrangement direction of the liquid inlet end 201 and the liquid outlet end 202, the guide component 300 has a guide wall 301 formed on the side opposite to the liquid outlet end 202, and the guide wall 301 is a streamlined curved surface.

[0087] In this technical solution, the guide component 300 can be formed with the aforementioned guide wall 301. Based on the aforementioned configuration, when the guide wall 301 faces the water flow, the resistance generated by the guide component 300 to the water flow can be relatively small. Therefore, during use, the guide component 300 is suitable for driving the collection component 200 to rotate under the action of the water flow until the aforementioned guide wall 301 faces the water flow. This results in the inlet end 201 and the outlet end 202 being arranged along the water flow direction, with the inlet end 201 located upstream of the outlet end 202. Based on this, the collection component 200 can adapt to the flow direction of the aforementioned surface water during use, and more stably and reliably access the aforementioned surface water flow through the inlet end 201 to intercept the solid floating objects carried by the aforementioned surface water flow. This improves the collection efficiency of the aforementioned floating object collection device for solid floating objects and reduces the need for drive equipment and manual intervention during use. Consequently, it can save the operating cost of the aforementioned floating object collection device and reduce the maintenance cost of the water environment in the aforementioned reservoir area.

[0088] Understandably, in practical applications, at least a portion of the guide wall 301 is submerged below the aforementioned water surface so that the guide assembly 300 is driven by the water flow.

[0089] It is understood that the specific shape of the guide wall 301 can be set according to actual needs. In conjunction with the foregoing, the shape of the guide wall 301 in actual applications can ensure that the flow resistance of the collecting component 200 and the guiding component 300 when the collecting component 200 is in the aforementioned working position is less than the flow resistance when the collecting component 200 is in other positions in the rotation direction. The specific shape of the guide wall 301 can be determined through experimental optimization, and no further limitations are imposed here. For example, the aforementioned streamlined surface can extend obliquely along the direction from the aforementioned inlet end to the aforementioned outlet end, and the aforementioned streamlined surface can include multiple sequentially connected surfaces with smooth transitions between adjacent surfaces; the shapes of the multiple aforementioned surfaces can be different, and the aforementioned surfaces can be, but are not limited to, circular arc surfaces, elliptical arc surfaces, parabolic surfaces, etc.

[0090] like Figure 1 As shown, in some examples, the arrangement directions of the inlet end 201 and the outlet end 202 are parallel to the rotation axis of the collection assembly 200 and pass through the reference section. The collection assembly 200 and the guide assembly 300 are both mirror-symmetric about the reference section.

[0091] In this technical solution, both the collection component 200 and the guiding component 300 can be configured to have a mirror-symmetric structure about a reference cross section. Based on the aforementioned configuration, with the inlet end 201 and the outlet end 202 arranged along the water flow direction, and the inlet end 201 located upstream of the outlet end 202, the force balance of the collection component 200 and the guiding component 300 can be improved. This helps the collection component 200 and the guiding component 300 maintain their posture, ensuring that the inlet end 201 faces the water flow and continuously receives water. This improves the reliability and collection efficiency of the floating debris collection device, further reducing the need for drive equipment and manual intervention during use, thereby saving on the operating cost of the floating debris collection device and reducing the maintenance cost of the water environment in the reservoir area.

[0092] Understandably, reference Figure 1 The aforementioned reference cross section can be a plane defined by the aforementioned dashed line X1 and the aforementioned dashed line X2. The statement that both the aforementioned collecting component 200 and the guiding component 300 are mirror-symmetric about the reference cross section means that the aforementioned collecting component 200 and the aforementioned guiding component 300 are mirror-symmetric about the aforementioned reference cross section.

[0093] like Figure 1 and Figure 2 As shown in the figure, in some feasible examples, the guide assembly 300 includes: fins 310 disposed in the collection assembly 200, and a guide wall 301 formed on the side of the fins 310 opposite to the liquid outlet 202 along the arrangement direction of the liquid inlet end 201 and the liquid outlet end 202; wherein, the number of fins 310 is two, and the two fins 310 are arranged symmetrically about the reference section.

[0094] In this technical solution, the guide component 300 may include two of the aforementioned fins 310. Based on the aforementioned arrangement, the guide component 300 can be composed of two spaced-apart fins 310, which helps to reduce the overall volume and structural complexity of the guide component 300, thereby saving the manufacturing cost of the guide component 300, and further reducing the force on the guide component 300 in the water flow, thus improving the stability of the aforementioned floating object collection device.

[0095] It is understandable that the guide walls 301 of the two fins 310 are mirror-symmetric about the aforementioned reference section.

[0096] For example, such as Figure 1As shown, with the extension direction of the dotted line X3 as the arrangement direction, the thickness direction of the aforementioned fin plate 310 is consistent with the aforementioned arrangement direction, and the two fin plates 310 are arranged at intervals along the aforementioned arrangement direction, with the fixing component 100 located between the two fin plates 310; correspondingly, the aforementioned guide wall 301 can be parallel to the aforementioned arrangement direction, which is beneficial to reduce the surface area of ​​the guide wall 301. In conjunction with setting the guide wall 301 as a streamlined curved surface, it is beneficial to further reduce the flow resistance of the guide wall 301 and increase the flow resistance difference between the guide wall 301 and other plate surfaces of the fin plate 310, thereby facilitating the aforementioned liquid inlet end 201 to meet the water flow.
