[0020] S1. First, move the device into the canal, move the waterwheel to one side of the canal, connect the first connecting pipe to the rotating pipe, and add an appropriate amount of water into the waterwheel;

[0021] S2, then start the water pump to pump water, the water can be sprayed on the inner wall of the canal through the first nozzle and sprayed on the edge through the second nozzle, flushing the silt and pushing the waterwheel driving device to move in the canal until the first connecting frame in front contacts the cover plate;

[0022] S3, then start the motor to drive the rotating tube to rotate, which can drive the first nozzle and the second nozzle to move back and forth for reciprocating flushing, and at the same time drive the second push rod to move up and down to resist the cover plate to move upward until the cover plate is loosened;

[0023] S4, then start the electric telescopic rod to extend, drive the support plate to move upward, lift the corresponding cover plate, start the motor to drive the lifting plate to rotate, adjust the positions of the two support plates, and start the electric telescopic rod to reset and move, put the front cover plate at the rear, and then start the motor to drive the rotating tube to rotate, which can drive the push rod to move back and forth, and push the placed cover plate into place;

[0024] S5. Finally, push the waterwheel forward and clean the areas one by one.

[0025] In the present application, first, the device is moved into the water channel, and the water wheel is moved to one side of the water channel, and the first connecting pipe is connected to the rotating pipe, and an appropriate amount of water is added into the water wheel;

[0026] Then the water pump is started to pump water, and the water can enter the rotating pipe through the first connecting pipe, flow into the first sliding rod through the hose, and finally enter the first nozzle through the second connecting pipe to spray on the inner wall of the canal and spray to the edge through the second nozzle to flush the silt and push the waterwheel driving device to move in the canal until the first connecting frame in front contacts the cover plate;

[0027] Then start the motor to rotate, and the rotation of the motor can drive the rotating tube to rotate through the two meshing gears, and the rotation of the rotating tube can drive the cam to rotate. During the rotation of the cam, the second nozzle can be pushed to move through the connecting rod, which can drive the first nozzle and the second nozzle to move back and forth for reciprocating flushing. During the movement of the second nozzle, multiple first push rods in front can be pushed to move at the same time, and the movement of the first push rod can drive the extension bar to move, and the movement of the extension bar can drive the wedge block to move, and the movement of the wedge block can drive the lifting bar to move upward, and drive the second push rod to lift up and lift the cover plate.

[0033] In the present invention, the environmentally friendly silt removal equipment for municipal water conservancy projects, through the coordinated use of the electric telescopic rod and the motor, not only realizes the automatic lifting and transportation of the cover plate, but also ensures the stability and accuracy of the transportation process through the meshing of the gear and the rotating tube. In addition, the coordination of the cam and the connecting rod enables the first nozzle and the second nozzle to reciprocate with the rotation of the rotating tube, further improving the flushing effect. Moreover, the connection method of the electric telescopic rod and the rotating ring effectively avoids the problem of the lifting plate being stuck with the electric telescopic rod during the rotation process, thereby enhancing the flexibility and durability of the structure.

DETAILED DESCRIPTION

[0045] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0046] Example 1

[0047] Reference Figure 1-Figure 8 An environmentally friendly dredging device includes: a canal 1 and a plurality of cover plates 2 evenly arranged in the canal 1 along its length direction, wherein the cover plates 2 cover the top of the canal 1 and are used for daily walking and preliminary isolation of dirt.

[0048] Two slide plates 8 are provided inside the water channel 1. The tops of the two slide plates 8 are fixed to the same connecting plate 9 by welding or bolts to ensure that the connecting plate 9 is stable. Rollers 10 are installed at the bottom and both sides of the slide plates 8 so that the entire frame can move smoothly along the length direction of the water channel 1.

[0049] A first sliding rod 11 is installed through one side of the connecting plate 9. The sliding rod 11 can slide freely along its axial direction. A plurality of second connecting pipes 12 are fixed on the outer wall of one end of the first sliding rod 11. The second connecting pipes 12 are divided into two groups, which are respectively connected to the first nozzle 13 below and the second nozzle 14 above. The first nozzle 13 is located in the canal 1, and the second nozzle 14 is located above the canal 1 for comprehensive flushing.

[0050] A waterwheel 6 is arranged on one side of the water channel 1, and clean water is stored in the waterwheel 6. A water pump 7 is installed on one side of the waterwheel 6. The water inlet end of the water pump 7 extends into the waterwheel 6 through a pipeline, and the discharge end is connected to one end of the first sliding rod 11 through a first connecting pipe 5.

[0051] A rotating tube 15 is installed through the top of the connecting plate 9, and a lifting plate 3 is sleeved on the outer wall of the rotating tube 15. Two first connecting frames 28 are fixedly provided at the bottom of the lifting plate 3. A supporting plate 4 is fixed to the outer side of each connecting frame 28 for lifting the cover plate 2. An electric telescopic rod 27 is installed on the top of the connecting plate 9, and its output end is connected to the lifting plate 3. The lifting and lowering of the lifting plate 3 is realized by the extension and retraction of the electric telescopic rod 27, thereby lifting the cover plate 2 in front.

[0052] The water pump 7 is rotatably connected to the top of the rotating tube 15 through the first connecting tube 5 to ensure that the water supply is not affected when the rotating tube 15 rotates. The bottom end of the rotating tube 15 is then connected to the inside of the first sliding rod 11 through a hose 18 to achieve soft transfer of water flow and ensure flexibility during flushing.

[0053] A motor 16 is installed at the bottom of the connecting plate 9, and a meshing gear 17 is fixedly sleeved on the output end of the motor 16 and the outer wall of the rotating tube 15. When the motor 16 is working, the meshing of the gear 17 drives the rotating tube 15 to rotate, thereby realizing the rotation of the support plate 4, and transporting the lifted cover plate 2 to the rear. A battery can be provided at the bottom of the waterwheel to power the water pump 7, the motor 16 and the electric telescopic rod 27.

[0054] Two clamping rings 45 for use are fixedly arranged on the top of the rotating tube 15 and the top of the lifting plate 3. When the lifting plate 3 descends and lifts the cover plate 2, the two clamping rings 45 can be firmly clamped to ensure that the lifting plate 3 is driven to rotate when the rotating tube 15 rotates.

[0055] A cam 47 is fixedly mounted on the outer wall of the rotating tube 15, and a connecting rod 48 that contacts the cam 47 is fixedly mounted on one side of the second nozzle 14. When the rotating tube 15 rotates, the cam 47 pushes the connecting rod 48 to move, thereby driving the second nozzle 14 and the first nozzle 13 to reciprocate, thereby improving the flushing effect.

[0056] A first spring 19 is sleeved on the outer wall of the first sliding rod 11, and its two ends are fixedly connected to the outer wall of one end of the first sliding rod 11 and one side of the slide plate 8 respectively. When the cam 47 pushes the connecting rod 48 to drive the nozzle to move, the first spring 19 is compressed, and vice versa, it drives the first sliding rod 11 to return to its original position, ensuring that the nozzle can move back and forth smoothly.

[0057] A plurality of first rectangular holes 33 are provided at the top of the support plate 4, and a plurality of second connection frames 41 corresponding to the first rectangular holes 33 are fixedly provided at the bottom of the support plate 4, and a plurality of guide rods 42 are slidably installed through the top of each second connection frame 41, and these guide rods 42 are used to guide the vertical movement of the lifting bar 34, and the lifting bar 34 is slidably provided in each first rectangular hole 33, and a plurality of second push rods 44 are fixedly connected to the top thereof, and these second push rods 44, driven by the lifting bar 34, can resist and loosen the cover plate 2.

[0058] In order to ensure that the lifting bar 34 can be lifted and lowered smoothly, a tension spring 43 is sleeved on the outer wall of the guide rod 42, and the two ends of the tension spring 43 are fixedly connected to the bottom of the lifting bar 34 and the bottom wall of the second connecting frame 41 respectively. In this way, when there is no external force, the tension spring 43 can keep the lifting bar 34 in a lower position, and when there is an external force such as the movement of the second nozzle 14, the lifting bar 34 will be pushed up, and then the cover plate 2 will be lifted up by the second push rod 44.

[0059] In order to ensure that the cover 2 can be smoothly moved into place during the transportation process, we have slidably set up a plurality of push rods 29 on one side of the first connecting frame 28, one end of which is fixedly connected to a second connecting strip 30, and the outer wall of the push rod 29 is fixedly sleeved with a limit ring 36 located in the first connecting frame 28 to prevent the push rod 29 from falling off. At the same time, the outer wall of the push rod 29 is also sleeved with a second spring 32, and the two ends of the second spring 32 are respectively fixedly connected to the first connecting frame 28 and the second connecting strip 30 close to each other. In this way, after detaching from the cover 2, the push rod 29 can automatically reset under the action of the second spring 32. One end of the push rod 29 is also provided with an inclined surface 35 for use with the front cover 2. When the support plate 4 moves upward, the cover 2 will contact the inclined surface 35, thereby pushing the push rod 29 to retract, making room for the placement of the cover 2.

[0060] The present application can be used in the field of environmental protection equipment, and can also be used in other fields applicable to the present application.

[0061] Example 2

Such a design can avoid the lifting plate 3 and the electric telescopic rod 27 from getting stuck when rotating, thereby ensuring the smooth operation of the equipment.

[0063] In order to realize the lifting and lowering of the lifting bar 34, a wedge block 39 is slidably set on one side of the second connecting frame 41. These wedge blocks 39 are used in conjunction with the lifting bar 34. At the same time, at the bottom of the first connecting frame 28, we have opened a second rectangular hole 37 corresponding to the lifting bar 34, and an extension bar 38 is slidably set in each second rectangular hole 37. The bottom of the extension bar 38 is fixedly connected to the wedge block 39, and one side of the extension bar 38 is fixedly provided with a first push rod 40. When the second nozzle 14 contacts the first push rod 40 during the movement, it will push the first push rod 40 and the extension bar 38 to move forward, and then drive the lifting bar 34 to rise through the wedge block 39.

[0064] In addition, in order to further improve the connection stability between the second nozzle 14 and the second connecting strip 30, we fixedly set two guide seats 21 on the top of the connecting plate 9, and slidably set a second sliding rod 20 in the guide seat 21, one end of the two second sliding rods 20 is fixedly connected to the second nozzle 14, and the other end is slidably set with an extension rod 22, a third spring 46 is provided in the second sliding rod 20, and the two ends of the third spring 46 are respectively fixedly connected to the inner wall of one side of the second sliding rod 20 and one end of the extension rod 22, and the other ends of the two extension rods 22 are jointly fixed with a convex strip 24, the top of the convex strip 24 is fixedly provided with a first connecting strip 23, and the bottom of the second connecting strip 30 is provided with a slot 31 adapted to the first connecting strip 23. When the cover plate 2 is placed in place, the first connecting strip 23 will automatically snap into the slot 31, thereby completing the snap connection between the convex strip 24 and the second connecting strip 30, and then pushing it into place.
