Description

Technical Field

[0001] This utility model relates to the field of river dredging technology, specifically a river ecological restoration dredging device for water conservancy projects. Background Technology

[0002] Rivers are important water conservancy facilities and an important part of the ecological environment. The key to river management is to strengthen river management. With the acceleration of industrialization and urbanization, the amount of domestic and industrial waste in rivers has increased. When carrying out river ecological restoration, floating garbage or dead branches and leaves in the river are retrieved and cleaned by manual dredging to prevent them from soaking in the water for a long time and polluting the river water and affecting the ecological environment.

[0003] The common method of river dredging involves workers operating dredging boats and using nets and other dredging tools to retrieve floating objects from the river surface, then piling the retrieved debris inside the dredging boat.

[0004] A search of patent document CN221608821U discloses a salvage device for river ecological restoration, comprising a salvage hull, a collection mechanism, and salvage components. The collection mechanism is installed on the upper surface of the salvage hull and includes a collection and collection component and an angle adjustment component. The collection and collection component is rotatably connected to the upper surface of the salvage hull and includes two symmetrically arranged collection plates. The angle adjustment component is fixedly connected to the collection and collection component. The salvage components are fixedly installed on the upper surface of the salvage hull and include several salvage plates that reciprocate in a circular motion. This invention changes the opening and closing angle between the two collection plates through the angle adjustment component, so that floating objects on the river surface are collected between the two collection plates during the salvage hull's movement, and then the salvage plates dredge the floating objects into the salvage hull. This achieves the change of the included angle between the collection plates, facilitates the adjustment of the salvage range, and simplifies the salvage operation.

[0005] Although the above-mentioned prior art can conveniently retrieve floating objects into the storage tank on the salvage vessel by using salvage components, when the salvage components retrieve floating objects, both the salvage mechanism itself and the floating objects themselves will carry water residue. The water will drip into the salvage vessel, causing water accumulation on the ground inside the salvage vessel and making the ground slippery. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-3 In this embodiment of the present invention, a river ecological restoration salvage device for water conservancy projects includes a salvage hull 1. The stern end of the salvage hull 1 is provided with an upwardly inclined guide trough 2. The guide trough 2 is fixedly connected to the salvage hull 1 by a vertical pole. The top of the guide trough 2 is fixedly connected with an downwardly inclined material collection trough 3. A collection box 4 is provided below the material collection trough 3. A gathering mechanism 5 is installed at the bottom end of the guide trough 2 on the salvage hull 1. Transmission rollers 6 are rotatably installed on the inner sides of both ends of the guide trough 2. The outer sides of the transmission rollers 6 are connected to a conveyor belt 7. Salvage plates 8 are fixedly connected on the conveyor belt 7. Multiple salvage plates 8 are arranged at equal intervals. A drive motor 9 is fixedly installed on the side wall of the guide trough 2 corresponding to the top transmission roller 6. The output end of the drive motor 9 is fixedly connected to the end of the corresponding transmission roller 6.

[0026] The floating objects are received below the conveyor belt 7 via the guide trough 2, and then guided to the collection box 4 via the material collection trough 3. During the salvage process, the water carried by the conveyor belt 7 and the floating objects drips down into the guide trough 2 and slides back into the river water, thus avoiding the problem of water dripping into the salvage hull 1 and thus avoiding the problem of water accumulation and slipperiness on the bottom of the salvage hull 1.

[0027] The bottom of the salvage vessel hull 1 is fixedly connected to the bottom of the collection box 4, and the collection box 4 is placed on top of the drainage trough 10. Drainage holes 11 are evenly opened at the bottom of the collection box 4. A water guide pipe 12 is fixedly connected to the bottom of the drainage trough 10, and one end of the water guide pipe 12 is fixedly connected to and communicates with the guide channel 2.

[0028] The collected floating objects are collected by the collection box 4, and the water is drained through the drain hole 11 and the drain trough 10. The drained water is then discharged through the water pipe 12, thus achieving the function of draining water.

[0029] The top of the drain trough 10 is provided with a stepped groove that corresponds to and fits the collection box 4. The bottom of the collection box 4 is inserted into the stepped groove. The side wall of the collection box 4 is symmetrically fixed with handles 13, which can be used to easily lift the collection box 4.

[0030] The collection box 4 is placed directly on top of the drain trough 10 through the step groove, and the collection box 4 can be lifted and lowered by the handle 13, which makes it convenient to pick up and replace the collection box 4.

[0031] The gathering mechanism 5 includes symmetrically arranged gathering plates 14. One end of the gathering plate 14 is rotatably connected to a rotating shaft 15. The rotating shaft 15 is fixedly connected to the salvage hull 1. One end of the gathering plate 14 corresponding to the rotating shaft 15 is fixedly connected to a toggle arm 16. The two toggle arms 16 are provided with a push groove 27 above their tail ends. The push groove 27 is a long groove.

[0032] A connecting pin 17 is fixedly connected to the top surface of the tail end of the actuating arm 16. The connecting pin 17 is inserted into the push groove 27 and is movably connected to the actuating arm 16. Guide rods 18 are symmetrically fixedly connected to the actuating arm 16. Guide sleeves 19 are slidably connected to the outer side of the guide rods 18. An electric push rod 20 is provided between the guide sleeves 19. The telescopic end of the electric push rod 20 is fixedly connected to the push groove 27. The electric push rod 20 and the guide sleeves 19 are both fixedly connected to the U-shaped plate 21. The U-shaped plate 21 is fixedly connected inside the salvage hull 1. The U-shaped plate 21 is fastened to the outer side of the water guide pipe 12, raising the electric push rod 20 and the guide sleeves 19 upward.

[0033] The gathering plate 14 has a sliding fastener with an extension groove 22 that is compatible with it. The top of the extension groove 22 is threadedly connected to a locking bolt 23. The extension groove 22 has a threaded hole for threaded connection of the locking bolt 23. The top surface of the gathering plate 14 has an adjustment hole 24 corresponding to the locking bolt 23. The locking bolt 23 and the adjustment hole 24 are compatible and matched.

[0034] Both the gathering plate 14 and the extension trough 22 are provided with drainage holes. These drainage holes increase the permeability of the gathering plate 14 and the extension trough 22, allowing water to pass through while intercepting floating debris. The retrieval plate 8 is also provided with drainage holes. These drainage holes allow the retrieval plate 8 to effectively drain water when retrieval and transporting floating debris, reducing the water content of the debris before it enters the collection box 4.

[0035] Each extension groove 22 has a fixed mounting groove 25 at its front end, and a deflection wheel 26 is rotatably mounted inside the mounting groove 25.

[0036] The gathering plate 14 can gather floating objects in the river channel to the conveyor belt 7 during the movement of the salvage vessel 1, thus facilitating salvage. The electric push rod 20 drives the guide sleeve 19 and guide rod 18 to move the push groove 27, which in turn kicks the actuating arm 16, causing the gathering plate 14 to rotate around the rotating shaft 15. This adjusts the opening angle of the gathering plate 14, making it easier to gather more floating objects. At the same time, the extension groove 22 can slide on the gathering plate 14 and extend outward, thereby further increasing the gathering range.

[0037] The installation of the baffle 25 and the deflector 26 can create a steering mechanism at the front end of the extension groove 22, which can help avoid direct collision when there is a collision with the riverbank.

[0038] Both the drive motor 9 and the electric push rod 20 are externally connected to a power source and a switch.

[0039] The working principle of this utility model is as follows:

[0040] In use, according to the required salvage range, the extension trough 22 is pulled outward from the gathering plate 14. At this time, the locking bolt 23 can be rotated and inserted into the corresponding adjustment hole 24 to form a fixation. Then, the electric push rod 20 is activated, which drives the push trough 27 to move. The push trough 27 moves along the sliding direction of the guide rod 18 and the guide sleeve 19. The push trough 27 moves the actuating arm 16 through the connecting pin 17. The actuating arm 16 causes the gathering plate 14 to rotate around the rotating shaft 15, thus forming an unfolding effect. At this time, the drive motor 9 is activated, which drives the corresponding transmission roller 6 to rotate. Under the action of the two transmission rollers 6, the conveyor belt 7 is driven to run. The running conveyor belt 7 drives the salvage plate 8 to move in a cycle. At this time, the salvage boat... Body 1 moves within the river channel, and floating objects in the river channel are gathered by the extension trough 22 and the gathering plate 14 to the position of the conveyor belt 7. At this time, the gathered floating objects are retrieved by the conveyor belt 7 through the retrieval plate 8. The floating objects retrieved on the retrieval plate 8 are carried upward and eventually fall into the collection trough 3 and slide into the collection box 4 for collection. After the floating objects fall into the collection box 4, the water on the surface of the floating objects continuously drips into the drainage trough 10 under the action of the drainage holes 11 and is discharged through the water guide pipe 12. During the process of the retrieval plate 8 retrieving the floating objects, the floating objects can be drained to a certain extent through the drainage holes on the retrieval plate 8. At the same time, during the operation of the conveyor belt 7, the water carried on the surface of the conveyor belt 7 is collected and discharged through the guide trough 2.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
