Description

Technical Field

[0001] This utility model relates to the technical field of dredging equipment for narrow channels, and in particular to a device for retrieving sediment from narrow channels. Background Technology

[0002] In the field of property management, exposed to the external environment, atmospheric precipitation washes away the ground, carrying impurities such as mud, dust, leaves, and dead branches into ditches. As the water flow slows down, these substances settle down. Fine soil particles from soil erosion around the ditches also enter and settle in the ditches. In addition, during the long-term process of water erosion, which cuts down the riverbed and erodes the soil on both sides to form gullies, substances are also deposited in the ditches. Heavy rains first carry away soil particles from the slope in low-lying areas to form small pits, which gradually expand into shallow ditches. Further erosion forms gullies, and a layer of loose soil accumulates at the bottom of the ditches. The cleanup of sediment in narrow ditches has always been a heavy and difficult task.

[0003] Existing traditional manual cleaning methods have many drawbacks. Mechanical suction is easily limited by environmental conditions, leading to difficulties in processing; rinsing with water wastes a large amount of water and generates more wastewater; while using a ladle removes less sediment each time and carries away wastewater, greatly increasing labor intensity. Furthermore, using other tools is often inconvenient and fails to thoroughly remove sediment. Therefore, it is essential to design a device that can effectively remove sediment from narrow channels and manholes. Among many options, this device for removing sediment from narrow channels and manholes has significant advantages. It is easy and convenient to operate, significantly improving work efficiency and effectively reducing environmental pollution, providing a more ideal solution for cleaning narrow channels and manholes in property management. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a device for retrieving sediment from narrow channels, which solves a series of problems existing in the cleaning of sediment from narrow channels and manholes in residential areas, improves cleaning efficiency, and achieves thorough sediment removal.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a device for scooping sediment from narrow channels, comprising a draining bucket, wherein the draining bucket has evenly distributed draining holes on all four sides, the perforated draining bucket is constructed of a perforated scoop-shaped metal sheet, and its unique arc-shaped structure on the receiving surface can effectively load sediment, the bucket consisting of 2 to 10... The bucket is composed of thin metal plates with millimeter-sized drainage holes. This not only reduces the weight of the structure but also effectively drains wastewater, reducing the pressure on subsequent wastewater treatment. Generally, the length-to-width ratio of the drainage bucket is set to 1.6–1.8:1, which provides good maneuverability and stability during use. A shovel is fixedly connected to the opening of the drainage bucket. A mounting block is fixedly connected to the left side of the drainage bucket. An output rod is threaded internally connected to the mounting block. A movable rod is slidably connected internally to the output rod. A positioning mechanism is fixedly connected to one side of the movable rod, which has evenly distributed through holes. Fastening components are installed externally on the output rod and movable rod to reinforce the tightness between them. Mounting rings are fixedly connected to the front and rear sides of the drainage bucket. Connecting components are installed inside the mounting rings, and handle rods are mounted on these connecting components. These handle rods can rotate along both sides of the bucket, approximately 1 / 2 of the distance from the opening of the drainage bucket. The handle is connected to the drain bucket via a flexible connecting rod. Under gravity, the bucket opening always faces downwards. This design allows the bucket opening to be inserted into the sediment more easily, facilitating subsequent cleaning operations. Furthermore, the output rod is a key component. It is connected to the top of the back of the drain bucket and consists of a movable rod and the output rod. Its length can be determined according to actual usage. In operation, the output rod provides additional downward force to the drain bucket, making it easier for the bucket opening to scoop up sediment, greatly improving cleaning efficiency. An anti-clogging mechanism is installed on the outside of the handle.

[0006] The positioning mechanism includes a second spring, which is fixedly connected inside the through hole. A positioning head is fixedly connected to one end of the second spring. A movable hole is opened on the side of the output rod close to the through hole. The positioning head is slidably connected inside the movable hole. A pressing component is fixedly connected to the outside of the movable hole. The pressing component is used to release the positioning head from fixing the movable rod, so that it can adjust the length of the output rod.

[0007] Preferably, the anti-blocking mechanism includes a sliding sleeve, which is installed on the outside of the handle rod. A connecting seat is fixedly connected to one side of the sliding sleeve. A folding frame is rotatably connected inside the connecting seat via a positioning pin. A movable head is rotatably connected to one end of the folding frame via a positioning pin. A striking rod is fixedly connected to one end of the movable head.

[0008] Preferably, the extrusion assembly includes a spring, one end of which is fixedly connected to the outside of the movable hole, and the other end of which is fixedly connected to a pressing element.

[0009] Preferably, the connecting assembly includes a buckle, which is installed inside the mounting ring. A fixing component is fixedly connected to one side of the buckle, which is used to securely install the buckle inside the mounting ring. A connecting flexible rod is fixedly connected to the outside of one side of the buckle, and a fixing sleeve is installed on the outside of the connecting flexible rod. The handle rod is installed outside the fixing sleeve.

[0010] Preferably, the fixing component includes an extension block, which is fixedly connected to one side of the buckle opening, and the extension block is internally threaded with two bolts.

[0011] Preferably, one side of the pressing member is installed inside the spring, and the end of the pressing member located inside the spring is slidably connected inside the movable hole to press the positioning head.

[0012] Preferably, the fastening assembly includes a threaded head, which is fixedly connected to the top of the output rod. A fastening sleeve is installed on the outside of the output rod and the movable rod. The fastening sleeve is threadedly connected to the threaded head to increase the tightness of the movable rod after adjustment.

[0013] Preferably, the handle rod and the output rod are the same and can be adjusted in length. The top of both the movable rod and the handle rod are fixedly connected to a stop, and a collar is installed inside the stop.

[0014] Preferably, the end of the output rod that is installed with the mounting block has an internal mounting hole, and a bolt is slidably connected to the mounting block and the mounting hole. A nut is externally threaded onto the side of the bolt with a threaded groove.

[0015] Preferably, the positioning head is slidably connected inside the through hole.

[0016] This utility model has the following beneficial effects:

[0017] 1. In this utility model, in order to adapt to different working conditions, the size of the drain bucket of the device can be flexibly changed. During operation, by disassembling the nut, bolt one, bolt two and unfastening the buckle in sequence, the power rod can be quickly separated from the bucket so as to replace the bucket of different sizes. The convenient disassembly and assembly design greatly enhances the on-site applicability and flexibility of the device.

[0018] 2. In this utility model, in order to adapt to trenches or manholes of different depths, the length of the output rod and the handle rod can be adjusted by pressing the pressing part. During operation, after pressing, pull the movable rod to the desired position, and release it to automatically lock it in place. Then tighten the fastening sleeve for secondary locking. After adjustment, use the output rod to push the shovel into the sediment, and then drag the handle rod horizontally to complete the retrieval. The drain hole on the drain bucket can automatically filter out sewage during the lifting process, effectively achieving solid-liquid separation, reducing the load and facilitating subsequent treatment.

[0019] 3. In this utility model, when the drain hole is blocked by small debris, the foldable striking rod can be pulled out and used to directly strike the bucket. The vibration will dislodge the blockage, thus avoiding the problem of increased labor intensity caused by the blockage preventing sewage from draining. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0029] Reference Figures 1-2 and Figure 4 This utility model provides an embodiment of a device for scooping sediment from narrow channels, comprising a draining bucket 1, with evenly distributed draining holes 2 on all four sides of the draining bucket 1, a shovel mouth 3 fixedly connected to the opening of the draining bucket 1, a mounting block 4 fixedly connected to the left side of the draining bucket 1, a force rod 5 threadedly connected to the inside of the mounting block 4, a movable rod 6 slidably connected to the inside of the force rod 5, and evenly distributed through holes 17 on one side of the movable rod 6, with a positioning mechanism fixedly connected inside the through holes 17. Fastening components are installed on the outside of the force rod 5 and the movable rod 6 to reinforce the fastening between the movable rod 6 and the force rod 5. Mounting rings 20 are fixedly connected to the inside of both the front and rear sides of the draining bucket 1, with connecting components installed inside the mounting rings 20. A handle rod 24 is mounted on the connecting components, and an anti-blocking mechanism is installed on the outside of the handle rod 24.

[0030] The positioning mechanism includes a second spring 18, which is fixedly connected inside the through hole 17. A positioning head 19 is fixedly connected to one end of the second spring 18. A movable hole 16 is opened on the side of the output rod 5 that is close to the through hole 17. The positioning head 19 is slidably connected inside the movable hole 16. A pressing component is fixedly connected to the outside of the movable hole 16. The pressing component is used to release the positioning head 19 from fixing the movable rod 6, so that it can adjust the length of the output rod 5.

[0031] The extrusion assembly includes a spring 15, one end of which is fixedly connected to the outside of the movable hole 16, and the other end of which is fixedly connected to a pressing member 14. One side of the pressing member 14 is installed inside the spring 15, and the end of the pressing member 14 located inside the spring 15 is slidably connected inside the movable hole 16 to extrude the positioning head 19. The positioning head 19 is slidably connected inside the through hole 17. The fastening assembly includes a threaded head 10, which is fixedly connected to the top of the output rod 5. A fastening sleeve 9 is installed on the outside of the output rod 5 and the movable rod 6. The fastening sleeve 9 is threadedly connected to the threaded head 10 to increase the fastening of the movable rod 6 after adjustment.

[0032] In practical use, workers can press the pressing part 14 according to the depth of narrow ditches, manholes, etc., so that one end of the spring 15 slides into the movable hole 16, pressing the positioning head 19. At the same time, the positioning head 19 presses the spring 18, causing it to store force and generate a rebound force. The positioning head 19 moves out of the movable hole 16 and into the through hole 17, no longer positioning the movable rod 6. The movable rod 6 can then be pulled upward. After adjusting to the required length, the pressing part 14 is released, so that the positioning head 19 is no longer pressed and re-clamped into the movable hole 16. Then, the fastening sleeve 9 is rotated downward to connect with the threaded head 10. Since the diameter of the movable rod 6 is smaller than that of the output rod 5, the movable rod 6 can be adjusted. After further tightening at the rear position, the same operation is performed on the handle rod 24 to complete the adjustment of the length of the output rod 5 and the handle rod 24. The opening of the drain bucket 1 can then be extended into the bottom of narrow ditches and manholes. Then, force is applied through the output rod 5 to scoop the opening of the drain bucket 1 into the sediment. Subsequently, the handle rod 24 is dragged laterally to load the sediment into the drain bucket 1. Since the drain bucket 1 has drain holes 2, when the sediment is scooped out, the sewage will drain out through the drain holes 2, thereby reducing the pollution of sewage to the environment and achieving effective separation of sediment and sewage. This provides convenience for subsequent sediment treatment and is applicable to narrow ditches and manholes of different depths, improving the practicality and flexibility of the device.

[0033] Reference Figure 1 and Figure 6 The anti-blocking mechanism includes a sliding sleeve 27, which is installed on the outside of the handle rod 24. A connecting seat 28 is fixedly connected to one side of the sliding sleeve 27. A folding frame 30 is rotatably connected inside the connecting seat 28 via a positioning pin 29. A movable head 31 is rotatably connected to one end of the folding frame 30 via a positioning pin 29. A striking rod 32 is fixedly connected to one end of the movable head 31.

[0034] When fine debris mixed in the sediment clogs the drain hole 2, the folding frame 30 is pulled, causing one end of the folding frame 30 to rotate in the connecting seat 28 via the positioning pin 29, thus unfolding the striking rod 32. Then, it is pulled to strike the drain bucket 1, causing the debris stuck in the drain hole 2 to be shaken out. This prevents the drain hole 2 from being blocked, thus avoiding the inability of sewage to be discharged, which would increase labor intensity. This achieves the purpose of ensuring the drainage function of the drain hole 2, reducing labor intensity, and improving work efficiency.

[0035] Reference Figures 1-3 and Figure 5The connecting assembly includes a retaining ring 21, which is installed inside the mounting ring 20. A fixing assembly is fixedly connected to one side of the retaining ring 21. The fixing assembly is used to securely install the retaining ring 21 inside the mounting ring 20. A connecting flexible rod 22 is fixedly connected to the outside of one side of the retaining ring 21. A fixing sleeve 23 is installed on the outside of the connecting flexible rod 22. A handle rod 24 is installed on the outside of the fixing sleeve 23. The fixing assembly includes an extension block 25, which is fixedly connected to one side of the opening of the retaining ring 21. A bolt 26 is threadedly connected to the inside of the extension block 25.

[0036] The handle rod 24 is the same as the output rod 5, and both can be adjusted in length. The top of the movable rod 6 and the handle rod 24 are fixedly connected to the stop 7, and the stop 7 has a collar 8 installed inside. The end of the output rod 5 that is installed with the mounting block 4 has a mounting hole 11. The mounting block 4 and the mounting hole 11 are slidably connected by a bolt 12. The bolt 12 has a threaded groove on one side and a nut 13 is externally threaded.

[0037] Considering the differences in different working environments, the device can be made in different sizes according to the specific usage environment and conditions. By rotating the nut 13 to separate it from the bolt 12, and then pulling the bolt 12, it can be pulled out of the mounting hole 11 and the mounting block 4 to complete the disassembly of the output rod 5. Then, the bolt 26 is rotated out of the extension block 25. Then, one side of the retaining ring 21 is pulled to open the retaining ring 21, which can be separated from the mounting ring 20 to complete the replacement of the size of the drain bucket 1. After the replacement is completed, the disassembly process is reversed to complete the installation of the retrieval device, making the device highly applicable and flexible.

[0038] Working principle: This device adjusts the lengths of the output rod 5 and the handle rod 24 according to the actual depth of the narrow channel of the manhole, so that the drain bucket 1 reaches a suitable length to penetrate the sediment layer. Then, the handle rod 24 extends the drain bucket 1 into the narrow channel or manhole. Due to gravity, the opening of the drain bucket 1 naturally faces downward. When the shovel tip contacts the sediment, force is applied to the output rod 5 to allow the drain bucket 1 to smoothly enter the sediment. Then, the movable rod 6 and the handle rod 24 are pulled to the right to fill the drain bucket 1 with sediment. After it is full, the movable rod 6 is lifted upward. The lever 6 and handle 24 allow the sediment to drain through the drain hole 2 into the drain bucket 1. After draining, the sediment is transported out of the manhole and narrow manhole channels. The entire process of cleaning sediment is smooth and can effectively clean sediment in narrow channels and manholes, improving work efficiency and reducing environmental pollution. When small debris mixed in the sediment blocks the drain hole 2, the folding frame 30 is pulled and the striking rod 32 is unfolded to strike the drain bucket 1, causing the debris stuck in the drain hole 2 to be shaken out, effectively ensuring the drainage effect of the drain bucket 1.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
