Description

Technical Field

[0001] The present application relates to the technical field of river ecological restoration, and in particular to a river ecological restoration device. Background Art

[0002] River ecological restoration refers to a series of measures to restore and improve damaged or degraded river ecosystems. It mainly includes restoring the natural form of the river, such as reshaping the curvature and slope of the river to increase the diversity and stability of the water flow. At the same time, it absorbs nutrients and pollutants in the water by planting aquatic plants, improves water quality, provides habitats and food sources for aquatic organisms, releases suitable aquatic animals, builds a complete aquatic ecological food chain, and promotes the balance of the ecosystem. It also includes repairing and protecting vegetation around the river, reducing soil erosion, filtering pollutants, and providing stable terrestrial ecological environment support for the river ecosystem. In addition, the water volume of the river is reasonably regulated to ensure the ecological water demand and maintain the ecological function of the river. River ecological restoration aims to restore the ecological integrity of the river, improve biodiversity, improve water quality, and enhance the stability and sustainability of the river ecosystem.

[0003] A Chinese patent with announcement number "CN221798373U" discloses a river channel ecological environment restoration device, which includes a river channel body, a pollution blocking plate is arranged in the river channel body, and mesh holes are opened on the pollution blocking plate; a support plate is fixedly arranged on the river channel body, and a working box is fixedly connected to the support plate; the pollution blocking plate is fixedly arranged at the bottom of the working box, and a dredging plate located in the river channel body is slidably arranged at the bottom of the working box; an anti-blocking rod corresponding to the position of the mesh holes is fixedly arranged on the dredging plate; a scraper is arranged on one side of the pollution blocking plate, and the scraper is slidably arranged up and down relative to the pollution blocking plate. The present application arranges a sliding dredging plate on one side of the pollution blocking plate, and uses the anti-blocking rod on the dredging plate to poke out the pollutants stuck in the mesh holes, and arranges a scraper to play a role in dredging and cleaning the pollution blocking plate, which can solve the problem that the existing river channel ecological environment restoration device is inconvenient to clean the pollutants stuck in the pollution blocking mesh holes.

[0004] Although the above-mentioned device has shown convenience to a certain extent during actual use, it still has obvious defects and shortcomings. Specifically, during use, although the device can intercept garbage and impurities in the river, it is unable to efficiently salvage the river garbage intercepted by the interception net. As the interception work continues, a large amount of garbage will gradually accumulate in front of the interception net, which will undoubtedly have a serious impact on the normal flow of the river. In addition, structures such as interception nets need to be in the river for a long time during the application process, which inevitably requires regular cleaning, replacement and maintenance. However, during actual use, the above-mentioned device is not easy to disassemble and clean quickly, which requires a lot of time and energy when performing maintenance work, greatly reducing work efficiency. In summary, the device has certain limitations during use and is in urgent need of improvement to improve its efficiency and practicality in river garbage treatment. Summary of the invention

[0017] In summary, this application includes the following beneficial technical effects:

[0018] The cleaning mechanism provided in the device has a remarkable effect in actual use. After the driving motor is started, the driving motor drives the active gear, and then the driven gear rotates, driving the rotating shaft to rotate, and the rotating shaft drives the fixed frame to rotate. The connecting frame is connected with the fixed frame for auxiliary driving to rotate the salvage frame. Due to the influence of gravity, the salvage frame always maintains a vertical state during the rotation process. When the salvage frame enters the water, as the river flows, the garbage enters the salvage frame through the entry trough. Multiple salvage frames rotate back and forth continuously to realize automatic and continuous salvage of surface garbage. During the cleaning process, the discharge trough fits the precast concrete wall. When the discharge trough of the salvage frame moves, the guide frame is squeezed and rotated. After the guide main frame passes over, the torsion spring resets and drives the guide frame to reset. The inclined filter guides the salvaged garbage to the outside of the precast concrete wall. This enables the device to continuously and automatically clean the garbage in front of the interception net, greatly improving the cleaning efficiency and convenience of use.

[0019] The cleaning mechanism cooperates with the fixing mechanism to facilitate the maintenance and replacement of the device. When the driving assembly and cleaning mechanism need to be cleaned or repaired, the connecting shaft is pulled out by pulling the bridge handrail to move the clamping block outward to the concave frame. At this time, the clamping block is separated from the limit groove, and the mounting plate can be pulled out from the vertical rail, and then the entire cleaning mechanism and driving assembly can be replaced. For the replacement of the intercepting net, because its two ends are installed by sliding with the slide plate and the slide rail, when it needs to be replaced, it only needs to be pulled out from the inside of the slide rail, which is convenient for quick maintenance and replacement. This design enables more efficient operation during the maintenance process, reducing maintenance time and cost;

[0020] The cleaning mechanism and fixing mechanism of this device cooperate with each other, showing powerful functions and advantages. The cleaning mechanism drives the gears to rotate through the driving motor, so that the rotating shaft and the fixing frame rotate, and then drives the salvage frame to automatically and continuously salvage garbage in the water. Under the action of gravity, the salvage frame always remains in a vertical state to ensure that the garbage can enter smoothly. During the discharge process, the design that fits the precast concrete wall and the cooperation of the guide frame and the inclined filter net enable the garbage to be accurately discharged to the designated position, realizing efficient garbage cleaning, and the fixing mechanism provides great convenience for the maintenance of the cleaning mechanism and the interception net. Whether it is the replacement of the cleaning mechanism and the driving component, or the inspection of the interception net, it can be quickly completed through simple operations. This design not only improves the practicality and reliability of the device, but also reduces maintenance costs and time. In river environment management, this device can effectively clean up river garbage and keep the river clean and ecologically balanced. It provides strong support for improving water environment quality and protecting aquatic organisms, and has broad application prospects and important practical significance.

The limiting groove 242 is opened on the outer side of the mounting plate 22 close to the concave frame 241. A clamping block 244 is fixedly installed at the end of the limiting spring 243. The end of the clamping block 244 passes through the vertical rail 21 and is inserted into the inner side of the limiting groove 242. A connecting shaft 245 is fixedly connected to the outer side of the clamping block 244. The end of the connecting shaft 245 passes through the concave frame 241 and is fixedly installed with a bridge handrail 246. An inclined surface 247 is opened on the top of the clamping block 244. The side shape of the clamping block 244 is a right-angle trapezoidal setting. The concave frame 241 is fixed to the outer side of the vertical rail 21 to provide an installation position for the limiting spring 243.

[0036] Please refer to Figure 1-Figure 5 and Figure 8The guide mechanism 7 includes a support arm 71, which is fixedly installed on the outer side of the precast concrete wall 1 away from the driving assembly 23. A guide main frame 72 is fixedly installed on the top of the support arm 71, and an elastic guide frame 73 is movably installed on the top of the guide main frame 72. The elastic guide frame 73 includes a fixed cylinder 731, which is fixedly installed on both sides of the upper end of the guide main frame 72. A torsion spring 732 is fixedly installed inside the fixed cylinder 731, and a rotating disk 733 is fixedly installed on the inner side of the torsion spring 732. A guide frame 734 is fixedly installed on the inner side of the rotating disk 733. The guide frame 734 is close to the driving assembly 23. One side of the assembly 23 extends to the lower side of a salvage frame 642. The support arm 71 is firmly fixedly installed on the outer side of the precast concrete wall 1 away from the side of the driving assembly 23, providing a stable support foundation for the entire guide mechanism 7. The guide main frame 72 on the top of the support arm 71 plays a major guiding role, providing a clear channel direction for the discharge of garbage. The fixed cylinder 731 in the elastic guide frame 73 is fixedly installed on both sides of the upper end of the guide main frame 72, ensuring the installation firmness of the elastic guide frame 73. The torsion spring 732 inside the fixed cylinder 731 can store and release energy for the guide frame 7 The activity of the guide frame 734 provides elastic restoring force, and the turntable 733 inside the torsion spring 732 enables the guide frame 734 to rotate flexibly to adapt to different working conditions. The side of the guide frame 734 close to the driving assembly 23 extends to the lower side of a salvage frame 642. When the salvage frame 642 is performing garbage salvage and movement, the guide frame 734 can be closely matched with the salvage frame 642. During the garbage cleaning process, when the discharge trough 644 of the salvage frame 642 moves to the guide frame 734 position, the guide frame 734 will be squeezed and rotated. This design ensures that the salvage frame 642 will not be moved during the movement. The garbage will not be hindered, and the garbage discharge operation can be carried out smoothly. When the salvage frame 642 passes over the guide frame 734, the torsion spring 732 resets and drives the guide frame 734 to reset. At this time, the inclined filter screen 643 can guide the salvaged garbage through the guide frame 734 and the guide main frame 72 to the outside of the precast concrete wall 1. This design ensures that the garbage can be accurately guided to the designated position, thereby improving the efficiency and accuracy of garbage cleaning. At the same time, the design of the elastic guide frame 73 also increases the flexibility and adaptability of the entire device, which can cope with different working conditions and garbage cleaning needs.

[0037] The implementation principle of a river ecological restoration device in an embodiment of the present application is as follows: by setting a cleaning mechanism 6, the device can be operated during actual use by starting a driving motor 233, and the driving motor 233 drives the active gear 234, thereby driving the driven gear 232 to rotate. When the driven gear 232 rotates, it can drive the rotating shaft 61 to rotate. During the rotation of the rotating shaft 61, it will drive the fixed frame 62 to rotate. During this period, since the connecting frame 63 and the fixed frame 62 are rotatably connected, they can assist in driving the salvage frame 642 to rotate. During the rotation of the fixed frame 62, the salvage frame 642 will be affected by gravity, prompting the fixed frame 62 to rotate adaptively, thereby making the salvage frame 642 always in a vertical state during the rotation displacement process. With the rotation displacement of multiple salvage frames 642, when the salvage frame 642 enters the water, as the river flows, the garbage can enter the salvage frame through the entry slot 645. Inside the salvage frame 642, at this time, as each salvage frame 642 rotates back and forth continuously, the garbage on the water surface can be automatically and continuously salvaged and cleaned, and in the process of cleaning, since the discharge trough 644 and the precast concrete wall 1 are in contact with each other, when the discharge trough 644 of the salvage frame 642 moves, the guide frame 734 will be squeezed and rotated, and when the guide main frame 72 passes over the guide frame 734, the torsion spring 732 resets and drives the guide frame 734 to reset. At this time, the inclined filter net 643 can guide the garbage salvaged inside it, and the salvaged garbage can be discharged to the outside of the precast concrete wall 1 through the guidance of the guide frame 734 and the guide main frame 72. In this way, the device as a whole can continuously and automatically clean the garbage in front of the interception net 4, which greatly improves the cleaning efficiency of the device during the overall use, and also significantly improves the convenience of the overall use of the device;

[0038] By arranging the cleaning mechanism 6 to cooperate with the fixing mechanism 2, when the device is in use, if it is necessary to clean or repair the drive assembly 23 and the cleaning mechanism 6, the bridge handrail 246 can be pulled out to pull the connecting shaft 245, and the connecting shaft 245 can be moved outward to pull the block 244 outward. When the block 244 moves to the inside of the concave frame 241, the block 244 and the limit groove 242 are separated from each other, and then the mounting plate 22 can be pulled out from the inside of the vertical rail 21. After the mounting plate 22 is pulled out, the entire cleaning mechanism 6 and the drive assembly 23 can be replaced. Overall, this design is convenient for cleaning, maintenance or replacement of structures such as the cleaning mechanism 6 and the drive assembly 23. Correspondingly, if the intercepting net 4 needs to be replaced, since the two ends of the intercepting net 4 are slidably mounted with each other through the slide plate 3 and the slide rail 5, when the intercepting net 4 needs to be replaced, it only needs to be pulled out from the inner side of the slide rail 5, which is convenient for quick replacement. The invention can be repaired and replaced quickly. Moreover, during use, when reinstalling after cleaning and maintenance, it is only necessary to adaptively insert the slide plate 3 into the slide rail 5 to install the slide plate 3 and the interception net 4 inside it. When the cleaning mechanism 6 needs to be installed, it is only necessary to insert the mounting plate 22 into the inner side of the vertical rail 21. When the bottom of the mounting plate 22 contacts the inclined surface 247 of the clamping block 244, the inclined surface 247 of the clamping block 244 is squeezed, and the clamping block 244 can resist the contraction of the limit spring 243. After the clamping block 244 contracts, the mounting block can be completely inserted into the interior of the vertical rail 21. At this time, the clamping block 244 can be driven to move outward by resetting the limit spring 243. The clamping block 244 can be inserted into the inner side of the limit groove 242 when it moves outward. The clamping block 244 and the limit groove 242 are mutually engaged and limited. Such a design is convenient for quickly installing the interception net 4, can improve the convenience of the overall use of the device, and facilitates the use of the device.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
