Description

Technical Field

[0001] This utility model relates to the technical field of river cleaning equipment, specifically a river cleaning device for water conservancy projects. Background Technology

[0002] With the increasing development of society, the pollution caused to the environment is becoming more and more serious. On the surface of many rivers or ditches, you can often see floating garbage such as plastic bags and plastic bottles. This garbage not only affects the quality of the river water and causes water pollution, but also seriously affects the ecological environment.

[0003] There is an existing river cleaning device for water conservancy projects with publication number CN217078668U. This device can intercept and collect floating garbage and debris, and process them regularly. The equipment has a high degree of mechanization, requires few personnel, and has high economic benefits. However, when using this device, the movement of the collection bucket causes the floating objects to move with the water flow, making it difficult to effectively collect the floating objects. Furthermore, this device is set in a fixed position, while the water level in the river is not constant, which leads to the inability to effectively collect floating objects when the water level changes. Therefore, it is necessary to design a river cleaning device for water conservancy projects to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a river cleaning device for water conservancy projects to solve the problems mentioned in the background art.

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.

[0017] Example 1 Please refer to Figure 1-6 As shown, this utility model provides a river cleaning device for water conservancy projects, including an installation frame 1 and a top frame 10 fixedly installed on the top of the installation frame 1. The front end of the installation frame 1 is provided with a lifting water guide frame 2. A filter screen frame 3 is fixedly connected to the inner side of the lifting water guide frame 2. A spiral sewage discharge rod 4 is provided on the inner side of the filter screen frame 3. The spiral sewage discharge rod 4 is rotatably connected to the lifting water guide frame 2. The lifting water guide frame 2 can collect floating objects on the water surface, and the filter screen frame 3 can block the floating objects while filtering out the water flow. The spiral sewage discharge rod 4 can be driven to rotate to quickly push the floating objects out. A sewage discharge frame 5 is provided on the left side inside the lifting water guide frame 2. A collection screen frame 6 is fixedly connected to the lower end of the sewage discharge frame 5. The sewage discharge frame 5 and the collection screen frame 6 can collect and process the floating objects in a concentrated manner. Limiting sliders 7 are slidably connected to the inner sides of the left and right side walls of the mounting frame 1. A fixing plate 8 is fixedly connected between the two limiting sliders 7. A lifting sleeve 9 is fixedly connected to the middle position of the upper end of the fixing plate 8. A top frame 10 is fixedly connected to the upper end of the mounting frame 1. A threaded rod 11 is rotatably connected to the middle position of the inner side of the top frame 10. The threaded rod 11 is screwed to the lifting sleeve 9. The lifting sleeve 9 can drive the fixing plate 8 and the limiting sliders 7 to move up and down through the rotation of the threaded rod 11. The limiting sliders 7 can limit the fixing plate 8 so as to drive the lifting water guide frame 2 to rise and fall, avoiding the problem that the fixed position is difficult to follow the water level change and thus affect the cleaning effect.

[0018] Specifically, a drive motor 12 is fixedly connected to the right end of the lifting water guide frame 2. The output shaft of the drive motor 12 is fixedly connected to the spiral drain rod 4. The spiral drain rod 4 can rotate by the drive motor 12, thereby realizing the automatic cleaning and discharge of the filtered floating objects.

[0019] Specifically, the front wall of the lifting water guide frame 2 is provided with a water inlet 13, and the lower wall of the lifting water guide frame 2 is provided with a drain outlet 14. Water can carry floating objects into the lifting water guide frame 2 through the water inlet 13, and the water can be discharged through the drain outlet 14.

[0020] Specifically, the right end wall of the sewage discharge frame 5 is provided with a discharge port 15, and the upper end of the sewage discharge frame 5 is rotatably connected with a lifting handle 16. Floating objects can be introduced into the sewage discharge frame 5 through the discharge port 15, and the floating objects in the collection net frame 6 can be easily recycled by pulling the lifting handle 16.

[0021] Specifically, the front inner side of the limit slider 7 is provided with a mounting bolt 17, which is spirally connected to the lifting water guide frame 2. The lifting water guide frame 2 can be fixedly installed on the limit slider 7 by the action of the mounting bolt 17.

[0022] Specifically, a stepper motor 18 is fixedly connected at the middle position of the upper end of the top frame 10. The output shaft of the stepper motor 18 is fixedly connected to the threaded rod 11. The self-locking property of the stepper motor 18 after rotation can stably control the rotation of the threaded rod 11 and ensure the stability after adjustment.

[0023] Specifically, a controller 19 is fixedly connected to the upper left side of the top frame 10. The controller 19 is electrically connected to the stepper motor 18. A radar level gauge 20 is electrically connected to the lower part of the controller 19. The radar level gauge 20 is fixedly connected to the fixed plate 8. The radar level gauge 20 can monitor water level changes in real time and transmit the information to the controller 19 so that the controller 19 can automatically control the start and stop of the stepper motor 18, making the device adjustment more timely and preventing floating objects from flowing down the river from the upper or lower end of the lifting guide frame 2 due to water level changes.

[0024] Working Principle: This utility model is a river cleaning device for water conservancy projects. When cleaning a river, the mounting frame 1 is first installed in the river channel. The radar water level gauge 20 monitors the water level in real time. When the water level changes, the information is transmitted to the controller 19, which then controls the stepper motor 18 to rotate. This causes the threaded rod 11 to rotate, which in turn drives the lifting sleeve 9 and the fixing plate 8 to move up and down. The limiting slider 7 then moves the lifting guide frame 2 up and down, and it is positioned inside the mounting frame 1 to limit the movement of the fixing plate 8. This allows the device to adjust according to changes in water level. The lifting guide frame 2 is adjusted to effectively collect and process floating objects on the water surface. Water flow carrying floating objects can enter the lifting guide frame 2 through the inlet 13. The water flow can be filtered by the filter screen frame 3 and discharged through the outlet 14. Floating objects can be blocked in the filter screen frame 3. The spiral sewage pipe can be rotated by driving the drive motor 12, so that the floating objects can enter the sewage discharge frame 5 through the discharge port 15 and fall into the collection screen frame 6, realizing the rapid and effective collection of floating objects. The sewage discharge frame 5 and the collection screen frame 6 can be pulled out by pulling the lifting handle 16, so as to recover the floating objects inside.
