[0065] Example 1

[0066] Refer to the instruction manual Figure 1-17 , a floating object cleaning device for water conservancy projects, comprising a dam body 1, a water outlet 2 opened on the dam body 1, and a grid structure for blocking floating objects from entering the water outlet 2 is arranged on the dam body 1;

[0067] The grid structure comprises a grid fixing frame 3 fixedly mounted on the dam body 1, and a plurality of vertically arranged fixed blocking rods 4 are fixedly connected to the grid fixing frame 3;

[0068] The interior of the grille fixed frame 3 is horizontally slidably connected with a moving frame 5, and the interior of the moving frame 5 is fixedly connected with a plurality of moving blocking rods 6 that cooperate with the fixed blocking rods 4;

[0069] The movable frame 5 is provided with a plurality of limit slide grooves at both ends, and the limit slide grooves are provided on one side of the movable blocking rod 6. Figure 3 , and the fixed blocking rod 4 is located inside the limiting slide groove; when in use, when the movable frame 5 is pushed to slide inside the grille fixed frame 3, the fixed blocking rod 4 slides relatively inside the limiting slide groove, and at this time, the movable blocking rod 6 can move toward or away from the fixed blocking rod 4, and when the movable blocking rod 6 and the fixed blocking rod 4 are attached, they form a blocking rod;

[0070] In the initial state, the movable barrier rod 6 and the fixed barrier rod 4 fit together, so that floating objects such as water plants, tree branches, plastic bags and other floating objects can be blocked to one side of the movable barrier rod 6 and the fixed barrier rod 4, and the relatively soft water plants and plastic bags will be entangled on the barrier rod composed of the movable barrier rod 6 and the fixed barrier rod 4, making it inconvenient to move and clean;

[0071] A control drive structure is provided on the grille fixing frame 3 for controlling the movable blocking rod 6 to move toward or away from the fixed blocking rod 4; the control drive structure can use a linear drive device such as a cylinder or an electric push rod to push the movable frame 5 to move inside the grille fixing frame 3, so that the movable blocking rod 6 and the fixed blocking rod 4 are fitted or separated.

[0072] A connecting member 7 is vertically slidably connected to one side of the grille fixing frame 3 near the water outlet 2, and the connecting member 7 is slidably connected to the grille fixing frame 3 up and down. This embodiment provides a sliding connection method, including a slide rail arranged on the grille fixing frame 3, and a sliding member slidably connected to the slide rail is fixedly connected to the connecting member 7, so that the connecting member 7 can slide up and down along the grille fixing frame 3, and a plurality of cleaning claws 8 are arranged on the connecting member 7;

[0073] When the movable barrier rod 6 and the fixed barrier rod 4 are in contact, the cleaning claw 8 is in a vertical state. At this time, the cleaning claw 8 is respectively located behind the adjacent movable barrier rod 6 and the fixed barrier rod 4. Figure 2 , the cleaning claw 8 is located behind the adjacent movable blocking rod 6 and the fixed blocking rod 4;

[0074] When the movable blocking rod 6 and the fixed blocking rod 4 are separated, the cleaning claws 8 are respectively located in the gaps between the adjacent movable blocking rods 6 and the fixed blocking rods 4. At this time, the cleaning claws 8 swing to be perpendicular to the fixed blocking rods 4. Figure 3 , the cleaning claw 8 is located at the gap between the adjacent movable blocking rod 6 and the fixed blocking rod 4;

[0075] The grille fixing frame 3 is provided with a cleaning driving structure for controlling the movement of the cleaning claws 8;

[0076] The cleaning drive structure includes a control shaft 9 rotatably connected to the connecting member 7, and one end of the cleaning claw 8 is fixedly connected to the control shaft 9;

[0077] Both ends of the control shaft 9 are fixedly connected with a driving plate 10, and the driving plate 10 is provided with two limit shafts 11 symmetrically arranged along the center of the control shaft 9;

[0078] Both sides of the grille fixing frame 3 are fixedly connected with guide plates 12 that match the limit shaft 11;

[0079] The connecting member 7 is pushed by a hydraulic cylinder to slide on the grille fixing frame 3; the hydraulic cylinder is fixedly installed on the grille fixing frame 3, and the hydraulic cylinder drives the connecting member 7 to slide up and down.

[0080] The guide plate 12 is set to a right-angled trapezoid, and the hypotenuse end of the guide plate 12 is located at the lower end of the grille fixing frame 3. The limit shaft 11 is provided with a sleeve that matches the guide plate 12. The sleeve is set on the limit shaft 11 so that after the sleeve and the guide plate 12 are in contact, the sleeve is used to reduce the friction between the limit shaft 11 and the guide plate 12.

[0081] In the initial state, the connecting member 7 is located at the bottom of the grille fixing frame 3. At this time, under the action of gravity, the end of the cleaning claw 8 away from the control shaft 9 is controlled to swing downward, and the cleaning claw 8 is controlled to be in a vertical state;

[0082] When in use, when it is necessary to clean floating objects, first push the movable frame 5 to move inside the grid fixed frame 3, and the fixed blocking rod 4 and the movable blocking rod 6 are separated, so that a certain gap is generated between the fixed blocking rod 4 and the movable blocking rod 6.

[0083] Subsequently, the hydraulic cylinder pushes the connecting member 7 to slide upward along the grille fixing frame 3. Figure 4 , when the connecting member 7 is along the grille fixing frame 3, the limiting shaft 11 located at the top first fits with the bevel of the guide plate 12. At this time, after being guided by the bevel of the guide plate 12, the limiting shaft 11 pushes the driving plate 10 to rotate, and the driving plate 10 drives the control shaft 9 to rotate. The control shaft 9 synchronously drives the cleaning claw 8 to rotate until the cleaning claw 8 and the fixed blocking rod 4 are in a vertical state, so that the cleaning claw 8 is inserted from between the fixed blocking rod 4 and the movable blocking rod 6. At this time, the limiting shaft 11 located at the top moves to one side of the guide plate 12. At the same time, when the driving plate 10 rotates, the limiting shaft 11 located at the other end of the driving plate 10 fits with the other side of the guide plate 12, so that the two limiting shafts 11 on the driving plate 10 fit with the two sides of the guide plate 12 respectively, so that the driving plate 10 is limited to the current position under the action of the limiting shaft 11 and the guide plate 12, and the cleaning claw 8 is limited to the current position by the control shaft 9;

[0084] Continue to push the connecting piece 7 to slide upward, so as to clean up the floating objects such as waterweed and plastic bags wound on the barrier rod composed of the fixed barrier rod 4 and the movable barrier rod 6, thereby cleaning up the waterweed and plastic bags wound on the barrier rod composed of the fixed barrier rod 4 and the movable barrier rod 6. At the same time, when the multiple cleaning claws 8 move upward, larger floating objects, such as plastic bottles and longer branches, are located between the multiple cleaning claws 8, so as to be cleaned up synchronously;

[0085] A collecting device for collecting floating objects is provided on the dam body 1, and the cleaning claws 8 clean the floating objects upwards into the collecting device.

[0086] The collecting device includes a primary collecting trough 18 slidably connected to the dam body 1, the primary collecting trough 18 is located at the upper end of the grille fixing frame 3, and an elastic member for pushing the primary collecting trough 18 to move toward the grille fixing frame 3 is provided between the primary collecting trough 18 and the dam body 1, and the elastic member adopts a compression spring;

[0087] A cleaning plate 22 is provided on one side of the primary collecting trough 18 close to the grille fixing frame 3. A plurality of cleaning grooves 23 cooperating with the cleaning claws 8 are provided at one end of the cleaning plate 22. The width of the cleaning grooves 23 matches the width of the cleaning claws 8 to ensure the cleaning effect.

[0088] In the initial state, the compression spring pushes the primary collecting slot 18 to move to the extreme position in the direction close to the grid fixing frame 3;

[0089] The connecting member 7 is provided with a pushing structure for pushing the primary collecting trough 18 to move in a direction away from the grille fixing frame 3. The pushing structure can adopt a linear driving device such as a hydraulic cylinder, an electric push rod, a cylinder, etc. to push the primary collecting trough 18 to move in a direction away from the grille fixing frame 3.

[0090] This embodiment provides a pushing structure, which includes a pushing plate 19 fixedly connected to both ends of the connecting member 7, and a rotating plate 20 that matches the pushing plate 19 is rotatably connected to both sides of the primary collecting tank 18, and the pushing plate 19 and the rotating plate 20 are both arranged in a trapezoidal shape;

[0091] A limit block 21 for limiting the rotating plate 20 is fixedly connected to the primary collecting tank 18. The limit block 21 is located above the rotating plate 20. A torsion spring is installed between the rotating plate 20 and the primary collecting tank 18.

[0092] refer to Fig.10 and Fig.11 In the initial state, under the action of the torsion spring, the rotating plate 20 swings toward the direction close to the limit block 21, and under the action of the limit block 21, the rotating plate 20 cannot swing upward.

[0093] When in use, when the connecting member 7 slides upward, the inclined surface of the pushing plate 19 contacts the inclined surface of the rotating plate 20, and then the connecting member 7 continues to slide upward, and the rotating plate 20 is pushed away from the grille fixing frame 3 by the pushing plate 19, so that the primary collecting groove 18 does not affect the upward sliding of the cleaning claw 8;

[0094] When the connecting member 7 continues to slide upward, the push plate 19 and the rotating plate 20 are separated, and the first-level collecting slot 18 is pushed to move to the limit position in the direction close to the grid fixing frame 3 under the action of the compression spring;

[0095] Then, the hydraulic cylinder pushes the connecting member 7 to slide downward, firstly making the lower end surface of the pushing plate 19 contact with the upper end surface of the rotating plate 20, and then the pushing plate 19 pushes the rotating plate 20 to swing downward, so that the rotating plate 20 compresses the torsion spring, so that when the connecting member 7 moves downward, it will not push the primary collecting tank 18 to move through the rotating plate 20, until the pushing plate 19 and the rotating plate 20 are separated, and the rotating plate 20 is pushed upward to the limit position under the action of the torsion spring and fits with the limit block 21, and the cleaning claw 8 passes through the cleaning groove 23, and the cleaning plate 22 isolates the floating objects collected between the cleaning claws 8 on one side of the cleaning plate 22. At this time, the floating objects on the cleaning claws 8 are collected inside the primary collecting tank 18. A plurality of water filtering holes are opened at the bottom of the primary collecting tank 18, and the water carried by the floating objects collected inside the primary collecting tank 18 leaks out through the water filtering holes;

[0096] Until the connecting member 7 slides downward to the limit position and the limit shaft 11 and the guide plate 12 are out of contact, under the action of gravity, the end of the cleaning claw 8 away from the control shaft 9 is controlled to swing downward, and the cleaning claw 8 is controlled to be in a vertical state.

[0097] Then, the movable frame 5 is pushed to move inside the grille fixed frame 3, and the fixed blocking rod 4 and the movable blocking rod 6 are fitted together.

[0098] Example 2

[0099] The cleaning plate 22 is rotatably connected to the primary collecting tank 18;

[0100] A guide groove 24 is formed at one end of the cleaning plate 22 away from the cleaning groove 23 , and a cleaning guide shaft 25 slidably connected to the guide groove 24 is fixedly connected to the dam body 1 .

[0101] When the primary collecting tank 18 moves in a direction away from the grille fixing frame 3, the cleaning plate 22 moves synchronously with the primary collecting tank 18. Under the pulling action of the cleaning guide shaft 25, the cleaning guide shaft 25 slides inside the guide groove 24, thereby pushing the cleaning plate 22 to swing toward the direction close to the inside of the primary collecting tank 18 through the guide groove 24 and the cleaning guide shaft 25; thereby, the floating objects cleaned up by the cleaning tank 23 and located on the cleaning plate 22 are swung toward the inside of the primary collecting tank 18, and the floating objects are collected into the first-level collecting tank 18.

[0102] Example 3

[0103] This embodiment provides a control driving structure, which includes a connecting rod 14 fixedly connected to the connecting member 7, the connecting rod 14 and the grille fixing frame 3 are slidably connected, and one end of the connecting rod 14 away from the connecting member 7 is connected to the hydraulic cylinder. When in use, the connecting rod 14 is pushed by the hydraulic cylinder to slide up and down;

[0104] Both sides of the connecting rod 14 are provided with pushing grooves 15 for controlling the movement of the moving frame 5;

[0105] The pushing groove 15 is composed of a vertically arranged limiting groove 15-1 and an inclinedly arranged control groove 15-2. The lower end of the control groove 15-2 is located at the upper end of the connecting rod 14, and the lower end of the control groove 15-2 is connected to the upper end of the limiting groove 15-1.

[0106] A control frame 16 matched with the connecting rod 14 is fixedly connected to the upper end of the moving frame 5 , and a driving shaft 17 slidably connected to the driving groove 15 is fixedly connected inside the control frame 16 .

[0107] In the initial position, the connecting member 7 is at the bottom, and the driving shaft 17 is located inside the control groove 15-2;

[0108] When in use, the connecting rod 14 is pulled upward by the hydraulic cylinder, and the driving shaft 17 is driven to move through the control groove 15-2, and the driving shaft 17 drives the moving frame 5 to move, so that the fixed blocking rod 4 and the moving blocking rod 6 are separated, and then the driving shaft 17 slides into the limiting groove 15-1, thereby fixing the moving frame 5 in the current position.

[0109] Example 4

[0110] A secondary filter screen 26 is installed on the water outlet 2, and the secondary filter screen 26 is used to further filter smaller floating objects in the water. A secondary collecting tank 29 is slidably connected to the dam body 1, and a pushing hydraulic cylinder is installed on the dam body 1 for pushing the secondary collecting tank 29 to slide up and down.

[0111] When in use, the secondary filter screen 26 will block the smaller floating objects that pass through the movable blocking rod 6 and the fixed blocking rod 4 to one side of the secondary filter screen 26, and the secondary collecting tank 29 will be driven by the hydraulic cylinder to slide up and down to collect the floating objects into the secondary collecting tank 29. The secondary collecting tank 29 that has risen to a high place is then cleaned. A plurality of spaced-apart water filtering holes are provided at the bottom of the secondary collecting tank 29, and water can flow out from the water filtering holes.

[0113] A collection box 33 which is easy to replace is installed inside the storage tank 30. The collection box 33 is easy to replace, so that it is easy to clean up floating objects.

[0114] When using, refer to Fig.17 When the secondary collecting trough 29 slides upward until one end of the swinging trough 31 contacts the guide block 32, the secondary collecting trough 29 continues to slide upward, and the guide block 32 pushes the end of the swinging trough 31 close to the guide block 32 downward, so that the other end of the swinging trough 31 tilts upward, thereby pushing the floating objects inside the swinging trough 31 into the collection box 33, thereby achieving the purpose of automatic cleaning.

[0115] After the work is completed, the secondary collecting tank 29 slides downward, the swinging tank 31 and the guide block 32 are out of contact, and the swinging tank 31 returns to the inside of the secondary collecting tank 29 under the action of gravity.

[0116] The swing groove 31 is tilted to facilitate its cooperation with the guide block 32 , so that after contacting the guide block 32 , it swings at a larger angle, making it easier for floating objects in the swing groove 31 to enter the collection box 33 .

[0117] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
