Description

Technical Field

[0001] This invention belongs to the field of water conservancy engineering technology, specifically relating to a trough-type fishway cleaning device and method. Background Technology

[0002] To utilize abundant water resources, the construction of dams and other water conservancy projects alters the natural morphology of rivers, changing the ecological environment and hydrological conditions necessary for the survival of fish, ultimately impacting fish resources, such as their migration patterns. To protect natural fishery resources and ensure the continuity and diversity of aquatic ecosystems, ecological compensation projects need to be constructed in areas where dams and other water conservancy projects have been built. In 2015, the National Energy Administration issued the "Design Code for Fish Passage Facilities in Hydropower Projects" (NB / T35054—2015), which classifies ecological compensation projects (fish passage facilities) into four categories: simulated natural channels, fish gates, fish collection and transportation systems, and fishways, with fishway projects being the most common.

[0003] Fishways, or fish passages, are channels for fish migration. They have become an important ecological compensation measure after the disruption of river connectivity, playing a vital role in maintaining fish populations and the stability of the fish ecosystem. To monitor the effectiveness of fishway operation and to collect detailed parameters such as the number of fish passing through, the identification of fish species, and the measurement of fish size, observation rooms or cameras are usually built on one side of the fishway. However, large amounts of algae can easily grow in fishways, and dust and mud can reduce the transparency of the observation room glass, making it impossible to properly observe the fish passing through the facilities. Current cleaning methods rely on regular manual cleaning, which is inefficient, slow, and ineffective, and also carries significant risks. Summary of the Invention

[0004] To address the aforementioned problems, embodiments of the present invention provide a trough-type fishway cleaning device and method.

[0005] The trough-type fishway cleaning device of the present invention includes: a cleaning trolley, which is installed at the top of the side wall of the fishway; a telescopic rod assembly, which passes through the cleaning trolley and is perpendicular to the side wall of the fishway; a rotating assembly, which is located at the end of the telescopic rod assembly and inside the fishway; a brush head assembly, which is installed below the rotating assembly and is used to drive the brush head assembly to rotate; and a controller, which is located inside the cleaning trolley and is connected to the telescopic rod assembly, the rotating assembly, and the brush head assembly.

[0006] Optionally, the telescopic rod assembly includes a telescopic rod housing that penetrates the cleaning trolley. A rack is installed inside the telescopic rod housing, and the rack is arranged along the length direction of the telescopic rod housing. A gear that meshes with the rack is fixed on one side of the inner wall of the telescopic rod housing. The gear is connected to the output shaft of a gear motor located on the outer wall of the telescopic rod housing. A position sensor is installed at the end of the rack away from the rotating assembly. Both the position sensor and the gear motor are connected to the controller.

[0007] Optionally, the rotating assembly includes a rotary motor located at the end of the rack, the switch of the rotary motor is connected to a controller, the output shaft of the rotary motor is connected to a turntable, and a brush head assembly is fixedly connected to the bottom of the turntable.

[0008] Optionally, the brush head assembly includes a first connecting rod fixedly connected to the turntable in the rotating assembly. Both sides of the middle portion of the first connecting rod are connected to L-shaped support rods, and the lower ends of the support rods are connected to limiting rods. The two limiting rods are located on both sides of the brush head.

[0009] Optionally, the bottom of the first connecting rod is connected to the drive motor, the switch of the drive motor is connected to the controller, the output shaft of the drive motor is connected to one end of the rotating plate, the other end of the rotating plate is connected to the rotating pin, the bottom of the rotating pin is connected to the top of the second connecting rod by a spring, and the bottom of the second connecting rod is hinged to the brush head.

[0010] Optionally, the brush head is in the shape of a quadrangular prism, with bristles on all four sides, each bristle being 5cm in length.

[0011] Optionally, a vision sensor is installed at one end of the brush head in the forward direction. The vision sensor is adjusted to monitor a distance of 5±1cm and is connected to the controller.

[0012] The method of using the trough-type fishway cleaning device of the present invention includes the following steps:

[0013] S1. The main switch of the controller is turned on, controlling the vision sensor to start working;

[0014] S2. When the vision sensor does not detect any obstacles, control the cleaning trolley to start, walk along the side wall of the fishway, and control the brush head to scrub the side wall of the fishway.

[0015] S3. When the vision sensor detects an obstacle, the cleaning cart stops and the telescopic rod assembly starts. When the position sensor does not detect the gear, the gear motor rotates forward, the rack extends outward, and the brush head scrubs the side wall of the transverse baffle in the fishway.

[0016] S4. When the rack 203 is extended to its maximum length, the brush head 409 moves to the end of the transverse baffle 6 in the fishway. The rotating component 3 controls the brush head 409 to rotate 180°. The vision sensor 410 does not detect any obstacles. The cleaning trolley starts, the telescopic rod assembly remains stationary, and the brush head brushes the end face of the transverse baffle.

[0017] S5. When the vision sensor detects an obstacle again, the cleaning cart stops, the telescopic rod assembly starts, and when the position sensor detects the gear, the gear motor reverses, the rack retracts inward, and the brush head scrubs the other side wall of the transverse baffle.

[0018] S6. After the rack retracts, the brush head rotates 180°. If the visual sensor does not detect any obstacles, the cleaning trolley starts, the telescopic rod assembly remains stationary, and the brush head continues to scrub the side wall of the fish passage.

[0019] The working process of the brush head in steps S1-S6 is as follows: the drive motor drives one end of the rotating plate to rotate, and the other end of the rotating plate drives the rotating pin to make a circular motion. During the circular motion, the rotating pin drives the second connecting rod to swing through the spring. Under the action of the limiting rod, the swing of the second connecting rod drives the brush head to move up and down, thereby brushing the side wall of the fish passage.

[0020] The beneficial effects of the embodiments of the present invention are that the cleaning trolley and brush head assembly of the trough-type fishway cleaning device of the present invention can automatically clean the fishway instead of manually, and the cleaning effect is good; by setting the rotating assembly and the telescopic rod assembly, the brush head can be rotated and the brush head can also brush the baffles in the trough-type fishway, which improves work efficiency and reduces the amount of manual labor.

[0034] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0035] like Figures 1-7 As shown, the trough-type fishway cleaning device of the present invention includes a cleaning trolley 1, a telescopic rod assembly 2, a rotating assembly 3, a brush head assembly 4, and a controller. The cleaning trolley 1 is installed at the top of the fishway sidewall 5 and moves along the fishway sidewall 5. The telescopic rod assembly 2 passes through the cleaning trolley 1 and is perpendicular to the fishway sidewall 5. The rotating assembly 3 is located at the end of the telescopic rod assembly 2 and is located inside the fishway. The brush head assembly 4 is installed below the rotating assembly 3 and is used to drive the brush head assembly 4 to rotate. The controller is located inside the cleaning trolley 1 and is connected to the telescopic rod assembly 2, the rotating assembly 3, and the brush head assembly 4. The brush head assembly 4 is used to brush the fishway sidewall 5 and the transverse baffles 6 inside the fishway. The rotating assembly 3 can drive the brush head assembly 4 to rotate 180°. The telescopic rod assembly 2 can drive the brush head assembly 4 to move along the transverse baffles 6 inside the fishway and brush the transverse baffles 6 inside the fishway. The cleaning trolley 1 can carry the brush head assembly 4 to move along the fishway sidewall 5.

[0036] The telescopic rod assembly 2 includes a telescopic rod housing 201 that penetrates the cleaning trolley 1. A rack 203 is installed inside the telescopic rod housing 201. The rack 203 is arranged along the length of the telescopic rod housing 201 and can extend or retract relative to the telescopic rod housing 201. A gear 204 that meshes with the rack 203 is fixed on one side of the inner wall of the telescopic rod housing 201. The gear 204 is connected to the output shaft of a gear motor 205 located on the outer wall of the telescopic rod housing 201. A position sensor 202 is installed at the end of the rack 204 away from the rotating assembly 3. Both the position sensor 202 and the gear motor 205 are connected to the controller.

[0037] Position sensor 202 can sense the position of gear 204. The controller controls the forward or reverse rotation of gear motor 205 based on whether position sensor 202 senses the position of gear 204. The forward or reverse rotation of gear motor 205 controls the extension or retraction of rack 203. The rotation of gear motor 205 drives gear 204 to rotate, which in turn drives rack 203 to move, thus achieving the extension or retraction of rack 203. The extension or retraction of rack 203 can drive brush head assembly 4 to move via rotating component 3. The maximum extension length of rack 203 is equal to the length of transverse baffle 6 inside the fish passage.

[0038] The rotating assembly 3 includes a rotary motor 301 located at the end of the rack 203. The switch of the rotary motor 301 is connected to a controller, and the output shaft of the rotary motor 301 is connected to a turntable 302. A brush head assembly 4 is fixedly attached to the lower part of the turntable 302. The rotary motor 301 can drive the turntable 302 to rotate, and the rotation of the turntable 302 can drive the brush head assembly 4 to rotate.

[0039] The brush head assembly 4 includes a first connecting rod 401 fixedly connected to the turntable 302 in the rotating assembly 3. Both sides of the middle portion of the first connecting rod 401 are connected to L-shaped support rods 402. Limiting rods 403 are connected to the lower ends of the support rods 402, and the two limiting rods 403 are located on both sides of the brush head 409. The bottom of the first connecting rod 401 is connected to a drive motor 404. The switch of the drive motor 404 is connected to a controller. The output shaft of the drive motor 404 is connected to one end of a rotating plate 405. The other end of the rotating plate 405 is connected to a rotating pin 406. The bottom of the rotating pin 406 is connected to the top end of a second connecting rod 408 via a spring 407. The bottom end of the second connecting rod 408 is hinged to the brush head 409.

[0040] When the drive motor 404 rotates, it will drive one end of the rotating plate 405 to rotate, thereby causing the other end of the rotating plate 405 to make a circular motion around the drive motor 404. The circular motion of the other end of the rotating plate 405 will drive the brush head 409 to move up and down along the limit rod 403 through the rotating pin 406, the spring 407, and the second connecting rod 408.

[0041] The brush head 409 is a quadrangular prism shape, and bristles 411 are provided on all four sides of the brush head 409. The bristles 411 are 5cm long.

[0042] A vision sensor 410 is installed at the top of the brush head 409 at the end facing forward. The vision sensor 410 is adjusted to monitor a distance of 5±1cm. The vision sensor 410 is connected to the controller. The vision sensor 410 is used to detect obstacles, namely the transverse baffle 6 in the fishway. The controller controls the cleaning cart 1 to start or stop based on whether the vision sensor 410 detects obstacles.

[0043] The method of using the trough-type fishway cleaning device of the present invention, as follows: Figure 6 and Figure 7 As shown, it includes the following steps:

[0044] S1. The main switch of the controller is turned on, and the vision sensor 410 starts working;

[0045] S2. When the vision sensor 410 does not detect any obstacles, the cleaning cart 1 is started and moves along the fishway sidewall 5, and the brush head 409 is controlled to scrub the fishway sidewall 5.

[0046] S3. When the vision sensor 410 detects an obstacle, the cleaning cart 1 stops, the telescopic rod assembly 2 starts, and when the position sensor 202 does not detect the gear 204, the gear motor 205 rotates forward, the rack 203 extends outward, and the brush head 409 brushes the side wall of the transverse baffle 6 in the fishway.

[0047] S4. When the rack 203 is extended to its longest length, the brush head 409 moves to the end of the transverse baffle 6 in the fish passage. The rotating component 3 controls the brush head 409 to rotate 180°. The vision sensor 410 does not detect any obstacles. The cleaning cart 1 starts, the telescopic rod component 2 remains stationary, and the brush head 409 brushes the end face of the transverse baffle 6 in the fish passage.

[0048] S5. When the vision sensor 410 detects an obstacle again, the cleaning cart 1 stops, the telescopic rod assembly 2 starts, and when the position sensor 202 detects the gear 204, the gear motor 205 reverses, the rack 203 retracts inward, and the brush head 409 brushes the other side wall of the transverse baffle 6 in the fishway.

[0049] S6. After the rack 203 has retracted, the brush head 409 rotates 180°. The vision sensor 410 does not detect any obstacles. At this time, the cleaning cart 1 starts, the telescopic rod assembly 2 remains stationary, and the brush head 409 continues to scrub the fishway sidewall 5, repeating steps S2-S6.

[0050] The working process of brush head 409 in steps S1-S6 is as follows: drive motor 404 drives one end of rotating plate 405 to rotate, and the other end of rotating plate 405 drives rotating pin 406 to make circular motion. During the circular motion, rotating pin 406 drives second connecting rod 408 to swing through spring 407. Under the action of limit rod 403, the swing of second connecting rod 408 drives brush head 409 to move up and down, thereby brushing the fish passage side wall 5 or the transverse baffle 6 inside the fish passage.
