Description

Technical Field

[0001] The invention relates to the field of water conservancy projects, and in particular to a water channel cleaning device for water conservancy projects. Background Art

[0002] A large amount of debris is often accumulated in the canal, such as algae and sedimentary garbage. Most of these algae and sedimentary garbage are attached to the bottom and slope of the canal. When cleaning, the algae attached to the bottom and slope of the canal must be manually scraped off, and then salvaged and cleaned. However, when the canal is flowing normally, most of these algae and sedimentary garbage will drift downstream with the water flow when they are stirred and scraped off, which can easily cause secondary pollution in the downstream area. At present, when people clean the algae in the canal, they often salvage them manually in the canal, which consumes a lot of manpower and has poor cleaning effect. Therefore, there is an urgent need for a canal cleaning device for water conservancy projects to solve the above problems. Summary of the invention

When the steel belt 42 passes around the transmission wheel 23, the guide pulley 8, the first guide pulley 10 and the second guide pulley 40, it is in the annular groove, and the annular groove can prevent the steel belt 42 from falling off.

[0019] The electric telescopic rod 3, the first electric telescopic rod 15, the first electric telescopic rod 31, the second motor 36, the second electric telescopic rod 39, the transmission motor 41, the first motor 44 and the PLC controller 48 are electrically connected to an external power source through wires.

[0021] The two steel belts 42 are both arranged between the two trapezoidal grids 4, and the opposite end surfaces of the two steel belts 42 are respectively in contact with the filter screens 4-3 on the opposite side walls of the two trapezoidal grids 4.

[0022] Working principle: When using the present invention, first place the device on the canal that needs to be cleaned (such as Figure 1 , 4 As shown in the figure, when moving the device on the canal, it is necessary to manually push the device from both sides of the canal, so that the device can be moved along the direction of the canal. When cleaning the algae in the canal, the device adopts a segmented cleaning method, and the canal is divided into a closed area by two trapezoidal grids 4 (water can flow through the filter screen 4-3 without affecting the circulation of water), and then the bottom and slope of the canal in the area between the two trapezoidal grids 4 are brushed by the brush roller 35, so that the algae and sedimentary garbage adhering to the bottom and slope of the canal are separated from the bottom and slope of the canal. The algae and the sedimentary garbage are separated (the algae and the sedimentary garbage are mixed with the water under the scrubbing and stirring of the brush roller 35). At this time, the algae and the sedimentary garbage mixed with the water are caught from the bottom of the canal between the two trapezoidal grid frames 4 by the salvage net 37 installed on the two steel belts 42, and the algae and the sedimentary garbage mixed with the water are separated and screened by the salvage net 37. Finally, the algae and the sedimentary garbage on the salvage net 37 are transferred to the bank of the canal and unloaded, effectively realizing the cleaning work of the algae and the sedimentary garbage in this section of the canal (the area between the two trapezoidal grid frames 4). The specific working process is as follows;

[0023] First, the telescopic ends of the two electric telescopic rods 3 are extended, driving the two trapezoidal grids 4 to be inserted into the canal. When the telescopic ends of the two electric telescopic rods 3 are extended to the maximum extent, the bottom surfaces and the inclined surfaces on both sides of the two trapezoidal grids 4 are just in contact with the inclined surfaces on both sides of the bottom surface of the canal, so that the area between the two trapezoidal grids 4 is separated. When cleaning the area between the two trapezoidal grids 4, the filter screen 4-3 can prevent algae or deposited garbage from floating away with the water flow. At this time, the telescopic ends of the four second electric telescopic rods 39 are extended, and at the same time, the telescopic ends of the two first electric telescopic rods 15 are also extended. As the telescopic ends of the two first electric telescopic rods 15 are extended, the distance between the two U-shaped plates 22 is shortened, so that the distance between the two corresponding transmission wheels 23 is also shortened. As the telescopic ends of the four second electric telescopic rods 39 extend, the second guide pulley 40 will press the steel belt 42 down synchronously, so that the steel belt 42 remains taut. Because the setting of the spring 21 can buffer the force exerted on the steel belt 42 when the second guide pulley 40 over-presses the steel belt 42, it protects the steel belt 42 and also tightens the steel belt 42. When the telescopic end of the second electric telescopic rod 39 is extended to the maximum extent, the two second guide pulleys 40 on the same steel belt 42 are respectively at the bottom of the canal; on both sides, at this time, the steel belt 42 between the second guide pulley 40 and the first guide pulley 10 will fit with the inclined surface of the canal, and the steel belt 42 between the two second guide pulleys 40 will fit with the bottom surface of the canal. The telescopic rod 31 runs, and the second motor 36 starts at the same time. The second motor 36 drives the brush roller 35 to rotate. When the first electric telescopic rod 31 runs, the telescopic end of the first electric telescopic rod 31 first extends to a certain extent (when the bottom of the brush roller 35 contacts the top of the canal slope, the telescopic end of the first electric telescopic rod 31 pauses for a while), and then the first motor 44 starts to run. When the first motor 44 runs, it can drive the first electric telescopic rod 31 and the brush roller 35 to move back and forth in the left and right directions through the lead screw 45 and the lead screw nut 47. With the operation of the first motor 44, the first electric telescopic rod 31 and the brush roller 35 slowly move to the right. As the brush roller 35 slowly moves to the right, the telescopic end of the first electric telescopic rod 31 continues to run at the same time. The telescopic end of the first electric telescopic rod 31 is first slowly extended, and the bottom of the brush roller 35 can always just contact the inclined surface of the water channel when it moves to the right and downward. When the telescopic end of the first electric telescopic rod 31 is extended to the maximum extent, the brush roller 35 begins to just contact the bottom surface of the water channel and moves to the right. When the brush roller 35 begins to contact the inclined surface on the other side of the water channel, the telescopic end of the first electric telescopic rod 31 begins to retract, and the bottom of the brush roller 35 can always just contact the inclined surface of the water channel when it moves to the right and upward. Similarly, when the first motor 44 drives the first electric telescopic rod 31 and the brush roller 35 to move to the left through the lead screw 45 and the lead screw nut 47, the first electric telescopic rod 31 and the first motor 44 also cooperate with each other.The brush roller 35 is always in contact with the inclined surface and bottom surface of the water channel during the movement. In this way, the brush roller 35 can effectively brush the algae and sedimentary garbage on the inclined surface and bottom surface of the water channel during the back and forth left and right movement, so that the algae and sedimentary garbage float in the water. After the first motor 44 drives the first electric telescopic rod 31 and the brush roller 35 to move back and forth several times (1-3 times) through the lead screw 45 and the lead screw nut 47, the first motor 44 drives the first electric telescopic rod 31 to move to the original position, and the first electric telescopic rod 31 also drives the brush roller 35 to rise to the original position. At this time, the two transmission motors 41 run quickly, so that the two transmission wheels 23 rotate synchronously in the counterclockwise direction, so that the two steel belts 42 are driven synchronously, and the two steel belts 42 drive the salvage net 37 into the water channel during the synchronous transmission. When the salvage net 37 completely enters the range between the two first guide pulleys 10, the transmission motor 41 stops running for a period of time (1-3 times). 3 minutes), at this time, the telescopic ends of the four second electric telescopic rods 39 begin to slowly retract, and at the same time, the telescopic ends of the two first electric telescopic rods 15 also begin to slowly retract, and the second guide pulley 40 no longer presses down the steel belt 42. As the distance between the corresponding two transmission wheels 23 becomes larger, the steel belt 42 bypassing between the two first guide pulleys 10 is finally stretched straight into a straight line. At this time, the salvage net 37 between the two steel belts 42 is also stretched straight along with the steel belt 42, and comes out of the water between the two trapezoidal grids 4. The salvage net 37 catches the algae and sedimentary garbage mixed with the water at the bottom of the canal between the two trapezoidal grids 4, and the water flows down from the mesh 37-2, while the algae and sedimentary garbage will remain on the salvage net 37. Then the transmission motor 41 continues to run until the salvage net 37 is moved back to its original position. In this process, when the salvage net 37 bypasses the transmission wheel 23 on the other side with the steel belt 42, the algae and sedimentary garbage on the salvage net 37 will be unloaded (such as, Figure 4 As shown in the figure, the garbage finally falls to the bank of the canal, thus completing the cleaning process of the algae in this section of the canal. When cleaning the next section of the canal, it is only necessary to push the device forward (the pushing distance is less than the spacing between the two steel belts 42), and continue to clean the algae in this area according to the above steps.

[0024] In the above working steps, the working sequence, working process and working time of the electric telescopic rod 3, the first electric telescopic rod 15, the first electric telescopic rod 31, the second motor 36, the second electric telescopic rod 39, the transmission motor 41 and the first motor 44 are all controlled by the PLC controller 48, so that the device can effectively achieve the purpose of automatic operation.
