Description

Technical Field

[0001] This utility model relates to the field of lake cleaning technology, specifically a floating debris collection and cleaning device for water conservancy lakes. Background Technology

[0002] As important carriers for water resource regulation, ecological conservation, and flood control and drainage, the water quality and ecological environment of lakes and ponds are directly related to regional water resource security and ecological balance. However, due to the influence of natural factors and human activities, lakes and ponds are prone to the accumulation of a large amount of floating debris, mainly including aquatic plant remains, domestic waste, agricultural non-point source pollutants, and industrial light waste.

[0003] The long-term accumulation of these floating objects can cause multiple problems: on the one hand, the floating objects covering the water surface will hinder the exchange of gases between the water and the atmosphere, reduce the dissolved oxygen content in the water, cause aquatic organisms to die from lack of oxygen, and disrupt the lake's ecological chain; on the other hand, the decomposition of floating objects will release nutrients such as nitrogen and phosphorus, exacerbate eutrophication of the water body, induce cyanobacterial blooms, and further deteriorate the water quality.

[0004] For example, Chinese utility model patent application number 201922277259.1 discloses a water surface floating debris collection device that is easy to clean. When the filter screen needs to be cleaned, the filter screen is pushed outward from the inside of the collection tank. The filter screen drives the guide block to move outward from the guide tank, so that the groove abuts against the protrusion, compressing and deforming the protrusion, allowing the guide block to move out of the guide tank, making it easy to disassemble and clean the filter screen. However, this device still has certain defects. Each time the filter needs to be cleaned, it needs to be disassembled, which makes the cleaning process more difficult and increases the workload for staff, thus reducing its practicality.

[0005] Therefore, we propose a floating debris collection and cleaning device for water conservancy lakes to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a floating debris collection and cleaning device for water conservancy lakes, so as to solve the problem mentioned in the background art that the filter screen needs to be disassembled every time it is cleaned, which brings certain difficulties to the cleaning operation, increases the workload of the staff, and has low practicality.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a floating debris collection and cleaning device for water conservancy lakes, comprising a mounting base and a collection frame, a support component mounted on the top of the mounting base, a connecting frame mounted on the upper right side of the support component, a ball screw mounted below the connecting frame via a bearing seat, a slider mounted on the ball screw, a movable bar mounted above the slider, and a collection frame mounted on the lower right side of the movable bar via an electric telescopic rod; The inside of the collection frame is equipped with a rotating shaft via a bearing seat, and blades are mounted on the rotating shaft. The left side of the collection frame is connected to a filter box, and a collection drawer is installed below the filter box. An adjusting shaft is mounted on the left side of the filter box via a bearing seat, and filter screens are installed on both the front and rear sides of the adjusting shaft.

[0008] Preferably, a servo motor is mounted on the upper left side of the support assembly, and the right side of the servo motor is connected to a ball screw via an output shaft.

[0009] With the above structural design, after the servo motor starts, it drives the ball screw below the connecting frame to rotate through the output shaft. When the ball screw rotates, the slider on it moves horizontally along the ball screw, which in turn drives the movable bar above the slider to move synchronously, thereby adjusting the horizontal position of the collection frame. This allows the collection frame to cover a larger area of ​​water, improves the efficiency of floating debris collection, and adapts to the cleaning needs of different lake areas.

[0010] Preferably, the movable strip runs through the support assembly, and the movable strip is slidably connected to the support assembly. The electric telescopic rod has a waterproof structural design.

[0011] With the above structural design, when the movable bar moves with the slider, the support component restricts the movement trajectory of the movable bar, preventing the movable bar from deviating and causing the collection box to be misaligned, thus ensuring collection accuracy; it also ensures that the electric telescopic rod works stably in humid environments and extends the service life of the equipment.

[0012] Preferably, the right side of the collection frame has an open structure design, a waterproof motor is installed on the top of the collection frame, and a connecting shaft is installed on the front surface of the waterproof motor through a bearing seat. The connecting shaft and the rotating shaft are connected by a connecting belt, and pulleys are installed on both the connecting shaft and the rotating shaft.

[0013] The above structural design facilitates the entry of lake water and floating objects. After the waterproof motor starts, it drives the connecting shaft to rotate through the output shaft. The connecting shaft and the rotating shaft are connected by a connecting belt, which in turn drives the rotating shaft to rotate. The blades on the rotating shaft rotate synchronously, generating water flow power to guide the lake water and floating objects into the collection frame together, instead of passively waiting for floating objects to enter, thus improving collection efficiency.

[0014] Preferably, the collection drawer is slidably connected to the filter box, and the left side of the collection drawer has multiple filter holes.

[0015] With the above structural design, when floating objects fall from the filter screen under the action of gravity, the collection drawer can catch these floating objects, realizing the centralized collection of floating objects; the multiple filter holes on the left side of the collection drawer can drain the collected water, preventing water from accumulating in the collection drawer, and preventing floating objects from being lost with the water, realizing the separation of floating objects and water, which facilitates the unified treatment of floating objects in the future.

[0016] Preferably, the filter screen is fixedly connected to the adjusting shaft, a connecting plate is installed at the upper end of the adjusting shaft, and a limit bolt is installed on one side above the connecting plate. Limit holes are opened on both the front and rear sides of the upper surface of the filter box, and the center line of the limit bolt coincides with the center line of the limit hole.

[0017] The above structural design ensures that the filter screen flips synchronously when the adjusting shaft rotates; a limit bolt is installed on the connecting plate at the upper end of the adjusting shaft. When the filter screen is in the cleaning position, the limit bolt is screwed into the corresponding limit hole on the upper surface of the filter box to fix the position of the adjusting shaft and the filter screen, preventing the filter screen from shifting during collection or cleaning, and ensuring the filtration and cleaning effect.

[0018] Preferably, a small motor is installed on the upper surface of the filter box, and the lower part of the small motor is connected to the adjustment shaft through an output shaft.

[0019] With the above structural design, after the small motor starts, it drives the adjustment shaft to rotate through the output shaft; the adjustment shaft drives the filter screens on the front and rear sides to rotate 180° synchronously to flip them over, eliminating the need for manual rotation of the adjustment shaft and reducing the difficulty of operation for staff; after flipping, the surface of the filter screen that was originally facing inward can be cleaned directly without disassembly, greatly improving the convenience of cleaning and reducing equipment downtime for maintenance.

[0020] Compared with the prior art, the beneficial effects of this utility model are: the floating debris collection and cleaning device for this water conservancy lake: 1. The synergy of "active diversion + high-efficiency filtration" improves the efficiency of floating debris collection. The device drives a connecting shaft via a waterproof motor above the collection frame, which in turn drives a rotating shaft and blades via a connecting belt. This actively guides lake water and floating debris into the collection frame, replacing the passive waiting for floating debris to enter and expanding the collection range. After the collected floating debris enters the filter box with the water, the filter screen accurately intercepts the floating debris, and the filtered water is discharged directly. At the same time, the collection frame can be flexibly adjusted in horizontal position and height via a servo motor, ball screw, and electric telescopic rod to adapt to the cleaning needs of different water levels and areas, greatly improving collection efficiency and applicability. 2. The filter screen can be cleaned without disassembly, reducing operation difficulty and maintenance costs. Cleaning the filter screen requires no disassembly: First, the collection frame is moved upwards using an electric telescopic rod. Then, a servo motor drives a ball screw to move the collection frame to the left. Some of the floating debris on the filter screen falls into the collection drawer below the filter box under gravity, and water is discharged through the filter holes of the collection drawer. Subsequently, rotating the adjusting shaft flips the filter screen 180°, allowing direct cleaning of any remaining floating debris on the inside of the filter screen. The filter screen is double-sided and can be used, avoiding the cumbersome operation of disassembling the filter screen in traditional devices, reducing the labor intensity of workers, minimizing equipment downtime for maintenance, and improving practicality.

[0023] 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. Example 1

[0024] Please see Figures 1-5This utility model provides a technical solution: a floating debris collection and cleaning device for water conservancy lakes, including a mounting base 1, a support assembly 2, a connecting frame 3, a ball screw 4, a servo motor 5, a slider 6, a movable bar 7, an electric telescopic rod 8, a collection frame 9, a rotating shaft 10, blades 11, a waterproof motor 12, a connecting shaft 13, a connecting belt 14, a filter box 15, a collection drawer 16, filter holes 17, an adjusting shaft 18, a filter screen 19, a connecting plate 20, a limiting bolt 21, and a limiting hole 22.

A servo motor 5 is mounted on the upper left side of the support assembly 2, and the right side of the servo motor 5 is connected to the ball screw 4 via an output shaft. After the servo motor 5 is started, it drives the ball screw 4 below the connecting frame 3 to rotate through the output shaft. When the ball screw 4 rotates, the slider 6 on it moves horizontally along the ball screw 4, thereby driving the movable strip 7 above the slider 6 to move synchronously, realizing the adjustment of the horizontal position of the collection frame 9. This allows the collection frame 9 to cover a larger area of ​​water surface, improves the efficiency of floating object collection, and is suitable for different lake areas. To meet cleaning requirements, a movable strip 7 is installed above the slider 6, passing through the support assembly 2. The movable strip 7 and the support assembly 2 are slidably connected. The electric telescopic rod 8 has a waterproof design. When the movable strip 7 moves with the slider 6, the support assembly 2 restricts the movement trajectory of the movable strip 7, preventing it from shifting and causing misalignment of the collection frame 9, thus ensuring collection accuracy. This also ensures stable operation of the electric telescopic rod 8 in humid environments, extending the equipment's lifespan. Furthermore, a collection frame 9 is installed on the lower right side of the movable strip 7 via the electric telescopic rod 8. The right side of the collection frame 9 has an open structure design, and a waterproof... The motor 12 is waterproof, and a connecting shaft 13 is mounted on the front surface of the motor 12 via a bearing seat. The connecting shaft 13 is connected to the rotating shaft 10 via a connecting belt 14. Both the connecting shaft 13 and the rotating shaft 10 are equipped with pulleys to facilitate the entry of lake water and floating objects. After the waterproof motor 12 is started, it drives the connecting shaft 13 to rotate via the output shaft. The connecting shaft 13 and the rotating shaft 10 are connected via the connecting belt 14, which in turn drives the rotating shaft 10 to rotate. The blades 11 on the rotating shaft 10 rotate synchronously, generating water flow power to guide the lake water and floating objects into the collection frame 9, replacing the passive waiting for floating objects to enter and improving collection efficiency.

[0025] Inside the collection frame 9, a rotating shaft 10 is mounted via a bearing seat, and blades 11 are mounted on the rotating shaft 10. The left side of the collection frame 9 is connected to a filter box 15, and a collection drawer 16 is installed below the filter box 15. The collection drawer 16 is slidably connected to the filter box 15, and multiple filter holes 17 are provided on the left side of the collection drawer 16. When floating objects on the filter screen 19 fall under the action of gravity, the collection drawer 16 can catch these floating objects, realizing the centralized collection of floating objects. The multiple filter holes 17 on the left side of the collection drawer 16 can drain the collected water, preventing water from accumulating in the collection drawer 16 and preventing floating objects from being lost with the water, thus achieving the separation of floating objects and water, which is convenient for subsequent unified treatment of floating objects.

[0026] An adjusting shaft 18 is mounted on the left side of the filter box 15 via a bearing seat. Filter screens 19 are mounted on both the front and rear sides of the adjusting shaft 18. The filter screens 19 are fixedly connected to the adjusting shaft 18. A connecting plate 20 is mounted on the upper end of the adjusting shaft 18, and a limit bolt 21 is mounted on one side of the upper part of the connecting plate 20. Limit holes 22 are opened on both the front and rear sides of the upper surface of the filter box 15. The center line of the limit bolt 21 coincides with the center line of the limit hole 22, ensuring that the filter screen 19 flips synchronously when the adjusting shaft 18 rotates. The limit bolt 21 is mounted on the connecting plate 20 at the upper end of the adjusting shaft 18. When the filter screen 19 is in the cleaning position, the limit bolt 21 is screwed into the corresponding limit hole 22 on the upper surface of the filter box 15 to fix the position of the adjusting shaft 18 and the filter screen 19, preventing the filter screen 19 from shifting during collection or cleaning, and ensuring the filtration and cleaning effect. Example 2

[0027] This utility model provides a technical solution: a floating debris collection and cleaning device for lakes and ponds. The difference between this embodiment and Embodiment 1 is that: A small motor is installed on the upper surface of the filter box 15, and the lower part of the small motor is connected to the adjusting shaft 18 through the output shaft. After the small motor is started, it drives the adjusting shaft 18 to rotate through the output shaft. The adjusting shaft 18 drives the filter screens 19 on the front and rear sides to rotate 180° synchronously to flip them over. There is no need to manually rotate the adjusting shaft 18, which reduces the difficulty of operation for the staff. After flipping, the surface of the filter screen 19 that was originally facing inward can be cleaned directly without disassembly, which greatly improves the convenience of cleaning and reduces the downtime of equipment maintenance.

[0028] Working principle: When using the floating debris collection and cleaning device for this water conservancy lake, first, place the mounting base 1 on the lake shore or the designated position of the cleaning boat, start the servo motor 5, and the servo motor 5 drives the ball screw 4 to rotate through the output shaft; the slider 6 on the ball screw 4 moves horizontally, driving the movable bar 7 to move synchronously; at the same time, start the electric telescopic rod 8, and the electric telescopic rod 8 extends and retracts to adjust the height of the collection frame 9 until the collection frame 9 moves to the required position to adapt to the water level and range of the current cleaning area.

[0029] Then, the active collection function is activated: the waterproof motor 12 is started, and the waterproof motor 12 drives the connecting shaft 13 to rotate through the output shaft; the connecting shaft 13 is connected to the rotating shaft 10 in the collection frame 9 through the connecting belt 14, which in turn drives the rotating shaft 10 to rotate; the blades 11 on the rotating shaft 10 rotate synchronously, generating water flow power to introduce lake water and floating objects into the collection frame 9 together, replacing the passive waiting for floating objects to enter and improving collection efficiency.

[0030] The collected mixture enters the filtration and separation stage: the lake water and floating objects in the collection frame 9 flow together to the filter box 15 connected to the left. The filter screen 19 on the left side of the filter box 15 intercepts the floating objects, and the filtered lake water is directly discharged from the filter box 15. Some of the intercepted floating objects are attached to the filter screen 19, and some fall into the collection drawer 16 below the filter box 15 under the action of gravity. The collection drawer 16 is slidably connected to the filter box 15, and the filter hole 17 on its left side can discharge the collected water, realizing the separation of floating objects and water and avoiding water accumulation.

[0031] When the filter screen 19 needs to be cleaned, a non-disassembly flipping cleaning is performed: First, the collection frame 9 is moved upward by the electric telescopic rod 8, and then the servo motor 5 is started to drive the ball screw 4 to move the collection frame 9 to the left, away from the lake surface; at this time, some of the floating objects remaining on the filter screen 19 continue to fall into the collection drawer 16 under the action of gravity, and the water is discharged through the filter hole 17; next, loosen the limit bolt 21 on the upper end connecting plate 20 of the adjusting shaft 18, and manually or by other power means rotate the adjusting shaft 18 to drive the filter screen 19 to rotate 180° synchronously and flip over; after flipping over, the limit bolt 21 is screwed back into the limit hole 22 on the corresponding side to fix the position of the adjusting shaft 18 and the filter screen 19, and the surface of the filter screen 19 that was originally facing inward can be cleaned directly without disassembly; after cleaning, the adjusting shaft 18 is operated in reverse to reset the filter screen 19, and then the collection drawer 16 is pulled out along the filter box 15 to empty the floating objects collected inside, thus completing a complete collection and cleaning process, thereby completing a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0032] 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.
