Description

Technical Field

[0001] This utility model relates to the technical field of ecological restoration equipment for riverbed sediment, specifically to an ecological restoration device for in-situ solidification of riverbed sediment. Background Technology

[0002] Ecological restoration devices for in-situ solidification of riverbed sediment are a type of equipment used to solidify polluted sediment without excavation and transportation, and combined with ecological restoration functions. The core of these devices is to transform highly fluid sediment with high pollutant content into a stable, solidified body that is difficult to release pollutants through physical, chemical, or biological means. Simultaneously, this improves the ecological environment of the sediment, achieving sediment reduction, stabilization, and ecological function restoration. Ecological restoration devices for in-situ solidification of riverbed sediment include mechanical mixing solidification devices, high-pressure jet grouting solidification devices, and integrated intelligent dosing and monitoring devices.

[0003] Currently, ecological restoration devices for in-situ mechanical mixing and solidification of riverbed sediment are typically installed on boats. As the boat moves, the mixing device agitates the riverbed sediment while simultaneously spraying a solidifying agent from nozzles. This mixes the sediment and the agent, and the solidifying agent reacts chemically with the water in the silt to form a gel-like substance, enhancing the strength and stability of the silt. However, traditional nozzles simply deliver the solidifying agent. When the equipment is stopped or idle, river water may backflow, leaving a small amount of unsprayed solidifying agent inside the nozzle. This reacts with the water to produce a sticky substance, which absorbs impurities in the water, forming a gel-like blockage that clogs the nozzle. Furthermore, the presence of chloride ions and sulfides in the river water can corrode the nozzle material, affecting its lifespan. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an ecological restoration device for in-situ solidification of riverbed sediment, which can effectively solve the problems mentioned in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ecological restoration device for in-situ solidification of riverbed sediment, comprising: a mechanical mixing arm and a nozzle, the nozzle being mounted on the mechanical mixing arm via a bracket, a nozzle being installed at the output end of the nozzle, an installation ring being fixedly connected to the inner wall of the nozzle, a baffle being provided below the installation ring, multiple sliding rods being fixedly connected to the upper end of the baffle, multiple sliding holes being opened through the upper end of the installation ring, the multiple sliding rods being slidably connected within the multiple sliding holes respectively, a spring being fitted onto the outer surface of the sliding rod, one end of the spring abutting against one side of the installation ring, a connecting rod being fixedly connected to the lower end of the baffle, a sealing cap being fixedly connected to one end of the connecting rod, and the sealing cap being located at the outlet of the nozzle.

[0006] As a further preferred embodiment of this technical solution, sealing rings are fixedly connected to the upper ends of both the sealing cover and the baffle, with the two sealing rings respectively snapped into the inner wall of the mounting ring and the outlet of the nozzle.

[0007] As a further preferred embodiment of this technical solution, a motor is installed at the upper end of the mechanical stirring arm, and a rotating rod is connected to the output end of the motor via a shaft coupling. The rotating rod is located inside the mechanical stirring arm, and stirring frames are rotatably connected to both sides of the mechanical stirring arm.

[0008] As a further preferred embodiment of this technical solution, one end of each of the two stirring racks is fixedly connected to a bevel gear two, and one end of the rotating rod is fixedly connected to a bevel gear one. The outer surface of the bevel gear one meshes with the two bevel gear two respectively. The mechanical stirring arm has an installation groove inside, and the bevel gear one and the two bevel gear two are rotatably connected to the inner wall of the installation groove.

[0009] As a further preferred embodiment of this technical solution, a lifting frame is fixedly connected to the other side of the mechanical stirring arm, an adjusting frame is slidably connected to one side of the lifting frame, a second motor is installed at the upper end of the adjusting frame, a threaded rod is rotatably connected to the inner wall of the second motor, one end of the threaded rod is connected to the output end of the second motor through a shaft coupling, and the outer surface of the threaded rod is threadedly connected to the threaded hole of the lifting frame.

[0012] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0013] 1. This utility model, through the structural design of a baffle, spring, sliding rod, and sealing cover, allows the curing agent pumped into the nozzle to stop being delivered when the equipment is stopped or idle. When the mounting ring is not under thrust, the reaction force of multiple springs pushes the sliding rod, causing it to slide within the sliding hole of the mounting ring. This pulls the baffle and sealing cover, placing them against the mounting ring and the nozzle outlet respectively, thus providing a double seal to the nozzle. This structural design automatically blocks the nozzle outlet when the nozzle stops delivering the curing agent, preventing river water from flowing back into the nozzle and nozzle. It also prevents residual curing agent in the nozzle from reacting with water to produce sticky substances that could clog the nozzle. Furthermore, it avoids chloride ions and sulfides in the river water from corroding the nozzle and affecting its service life.

[0014] 2. This utility model, by turning on the second motor, causes the threaded rod to drive the lifting frame to slide within the adjusting frame, raising the mechanical stirring arm from the river water. The mechanical stirring arm can then be removed from the spray pipe by rotating the nozzle with a tool. The stirring frame can also be maintained. This structural design facilitates the repair and replacement of the structure on the mechanical stirring arm, improving the convenience of using the equipment. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] This utility model provides a technical solution: such as Figure 1 - Figure 6 As shown in this embodiment, an ecological restoration device for in-situ solidification of riverbed sediment includes: a mechanical mixing arm 1 and a nozzle 2. The nozzle 2 is mounted on the mechanical mixing arm 1 via a bracket. A nozzle 3 is installed at the output end of the nozzle 2. An installation ring 14 is fixedly connected to the inner wall of the nozzle 3. A baffle 15 is provided below the installation ring 14. A plurality of sliding rods 16 are fixedly connected to the upper end of the baffle 15. A plurality of sliding holes are opened through the upper end of the installation ring 14. The plurality of sliding rods 16 are slidably connected in the plurality of sliding holes. A spring 17 is fitted on the outer surface of the sliding rod 16. One end of the spring 17 abuts against one side of the installation ring 14. A connecting rod 19 is fixedly connected to the lower end of the baffle 15. A sealing cap 20 is fixedly connected to one end of the connecting rod 19. The sealing cap 20 is located at the outlet of the nozzle 3.

[0026] Through the structural design of baffle 15, spring 17, sliding rod 16 and sealing cover 20, when the equipment is stopped or idle, the curing agent pumped into the nozzle 2 stops being delivered. When the mounting ring 14 is not pushed, the reaction force of multiple springs 17 pushes the sliding rod 16, which slides in the sliding hole of the mounting ring 14, pulling the baffle 15 and sealing cover 20. The baffle 15 and sealing cover 20 are respectively abutted against the mounting ring 14 and the outlet of the nozzle 3, providing a double seal for the nozzle 3. This structural design can automatically block the outlet of the nozzle 3 when the nozzle 2 stops delivering the curing agent, preventing river water from flowing back into the nozzle 3 and nozzle 2, preventing a small amount of residual curing agent in the nozzle 2 from reacting with water to produce sticky substances and causing the nozzle 2 to become blocked, and preventing chloride ions and sulfides in the river water from corroding the nozzle 2 and affecting its service life.

[0027] It should be noted that the size of the baffle 15 is smaller than that of the mounting ring 14; the inlet of the nozzle 2 is connected to a telescopic hose, and a pump is installed at one end of the telescopic hose, which draws the curing agent into the nozzle 2.

[0028] like Figure 5 and Figure 6As shown, sealing rings 18 are fixedly connected to the upper ends of sealing cover 20 and baffle 15. The two sealing rings 18 are respectively snapped into the inner wall of mounting ring 14 and the discharge port of nozzle 3. The two sealing rings 18 seal the gaps between nozzle 3 and sealing cover 20, mounting ring 14 and baffle 15 to prevent river water from entering the spray pipe 2 and nozzle 3 through the gaps.

[0029] like Figure 3 and Figure 4 As shown, a motor 5 is installed at the upper end of the mechanical stirring arm 1. The output end of the motor 5 is connected to a rotating rod 11 via a shaft coupling. The rotating rod 11 is located inside the mechanical stirring arm 1. Stirring frames 4 are rotatably connected to both sides of the mechanical stirring arm 1. One end of each of the two stirring frames 4 is fixedly connected to a bevel gear 13. One end of the rotating rod 11 is fixedly connected to a bevel gear 12. The outer surface of the bevel gear 12 meshes with the two bevel gears 13 respectively. An installation groove is opened inside the mechanical stirring arm 1. The bevel gear 12 and the two bevel gears 13 are rotatably connected to the inner wall of the installation groove. By turning on the motor 5, the bevel gear 12 and the two bevel gears 13 mesh, causing the two stirring frames 4 to rotate simultaneously, stirring the riverbed sediment. At the same time, a solidifying agent is sprayed out through the spray pipe 2 to improve the ecological environment of the sediment.

[0030] like Figure 1 and Figure 2 As shown, a lifting frame 6 is fixedly connected to the other side of the mechanical stirring arm 1. An adjusting frame 7 is slidably connected to one side of the lifting frame 6. A motor 8 is installed at the upper end of the adjusting frame 7. A threaded rod 10 is rotatably connected to the inner wall of the motor 8. One end of the threaded rod 10 is connected to the output end of the motor 8 through a shaft coupling. The outer surface of the threaded rod 10 is threadedly connected to the threaded hole of the lifting frame 6.

[0031] By turning on motor 8, threaded rod 10 drives lifting frame 6 to slide within adjusting frame 7, raising mechanical stirring arm 1 from the river water. Then, using a tool, nozzle 3 is rotated to remove it from spray pipe 2 for replacement. This also allows for maintenance of stirring frame 4. This structural design facilitates the repair and replacement of the structure on mechanical stirring arm 1, improving the convenience of equipment use.

[0032] like Figure 1 and Figure 2 As shown, a mounting frame 9 is fixedly connected to one side of the adjustment frame 7, and multiple mounting holes are opened through one side of the mounting frame 9; by passing the fixing bolts through the mounting holes, the adjustment frame 7 is fixed to the boat, so that the equipment moves with the boat as the boat moves, thereby improving the bottom sediment ecological environment.

[0033] like Figure 2 and Figure 3As shown, guide plates 21 are fixedly connected to both sides of the lifting frame 6. The two guide plates 21 are symmetrical to each other, and one side of each guide plate 21 is slidably connected to the two sides of the adjusting frame 7. Through the structural design of the guide plates 21, the sliding direction of the mechanical stirring arm 1 is guided, and the two guide plates 21 can enhance the stability on the adjusting frame 7.

[0034] This utility model provides an ecological restoration device for in-situ solidification of riverbed sediment, and its specific working principle is as follows:

[0035] When carrying out ecological restoration of riverbed sediment, firstly, the regulating frame 7 is installed on the boat, the motor 8 is turned on, and the mixing frame 4 on the mechanical mixing arm 1 is moved to the riverbed sediment. Then, the hose at one end of the pump on the boat is connected to the feed end of the nozzle 2, the motor 5 is turned on, the mixing frame 4 turns up the sediment, and at the same time the pump is turned on to deliver the solidifying agent into the nozzle 2. The turned-up sediment mixes with the solidifying agent, improving the ecological environment of the sediment. When the equipment is stopped or idle, the solidifying agent pumped into the nozzle 2 stops being delivered. When the mounting ring 14 is not pushed, the reaction force of multiple springs 17 pushes the sliding rod 16, which slides in the sliding hole of the mounting ring 14, pulling the baffle 15 and the sealing cover 20. The baffle 15 and the sealing cover 20 are respectively abutted against the mounting ring 14 and the discharge port of the nozzle 3, providing a double seal for the nozzle 3. This structural design can automatically block the discharge port of the nozzle 3 when the nozzle 2 stops delivering the solidifying agent, preventing river water from flowing back into the nozzle 3 and the nozzle 2.
