Description

Technical Field

[0001] The present invention belongs to the technical field of water treatment equipment, and specifically relates to an environmentally friendly treatment method for epiphytic algae on the slopes of channels. Background Art

[0002] Most of the cross-basin water transfers are connected through newly built channels. However, it takes a certain amount of time for the ecosystem of the newly built channels to reach a balanced and stable state. Therefore, there is a risk of abnormal proliferation of epiphytic algae on the channel slopes. If the epiphytic algae abnormally proliferate, it will affect the water supply safety, water quality safety, and engineering safety of the channels. Therefore, cleaning the epiphytic algae attached to the slopes and eliminating the potential risk hazards that the abnormal proliferation of epiphytic algae may bring to the channels have become technical problems that need to be solved urgently.

[0003] At present, in the technologies for removing epiphytic algae on slopes at home and abroad, in order to avoid the problem of secondary pollution to water quality, physical removal methods are often used, mainly including manual cleaning, mechanical friction cleaning, etc. Using manual cleaning not only has a large labor intensity and low efficiency, but also causes a large amount of dirt to spread into the water, resulting in secondary pollution, and cannot completely remove the epiphytic algae buried in the visual blind area by deep water. The mechanical friction cleaning method is widely used and has obvious effects. It can directly remove some epiphytic algae in the water body. However, the existing mechanical removal devices have a complex structure. On the one hand, when the cleaning device is operating, there are also sealing problems caused by underwater mechanical transmission, which are prone to cause secondary pollution; on the other hand, there are disadvantages such as the inability to eradicate the algae with short-term abnormal proliferation and low efficiency in the operation area. Therefore, an environmentally friendly treatment method for epiphytic algae on the slopes of channels with good cleaning effect, high operation efficiency, and environmental protection during the cleaning process is needed.

The ring-shaped sealing block is connected to the bottom of the fixed mounting plate through the countersunk bolts. A through hole is arranged at the central part of the fixed mounting plate. An air suction pipeline is installed in the through hole. The air suction pipeline is connected to an air suction pump. A filter screen is arranged at the lower end of the through hole. A connecting air hole is arranged on one side of the through hole. A solenoid valve is arranged at the upper end of the connecting air hole. A fixed connecting rod is arranged between the fixed mounting plate and the mounting channel steel. The top end of the fixed connecting rod is connected to the mounting channel steel, and the bottom end of the fixed connecting rod is connected to the lower surface of the fixed mounting plate. A blowing pipeline is arranged on the side surface of the fixed mounting plate. The blowing pipeline is connected to a gas supply pump. The inner side of the longitudinal section of the outer positioning ring slopes outward from low to high, the outer side of the longitudinal section of the inner positioning ring slopes inward from low to high, the longitudinal section of the annular positioning groove is an isosceles trapezoid with a longer upper base and a shorter lower base, and the longitudinal sections of the plugging block and the upper half of the longitudinal section of the annular plugging groove are both isosceles trapezoids with a shorter upper base and a longer lower base.

[0011] The specific operation process of step (2) is as follows: The heavy truck drives forward along the road on the bank of the channel. During the driving process, the air blowing pipeline on the outer circular surface of the outer positioning ring blows air to the ground under the air supply of the air supply pump, dispersing the dust and small particles on the ground. After the heavy truck drives to the working position, it parks, turns off the air supply pump, and starts all the first lifting hydraulic cylinders and the second lifting hydraulic cylinders. The first lifting hydraulic cylinders and the second lifting hydraulic cylinders extend synchronously to drive all the sucker assemblies to descend. When the outer rubber ring and the inner rubber ring of the sucker assembly contact the road surface, the air suction pump is started, and air is sucked through the air suction pipeline to form a negative pressure in the cavity between the fixed mounting plate, the inner rubber ring and the ground, thereby making the sucker assembly tightly suck the road surface. Since the negative pressure adsorption anti-rollover device is arranged on the left side of the heavy truck, that is, on the side far from the channel slope, the heavy truck is positioned by negative pressure adsorption on the road surface, thus preventing the heavy truck from tipping to the left during the operation of the mechanical telescopic boom device and the cleaning device in the cantilever state.

[0012] The specific operation process of step (3) is as follows: The mechanical telescopic boom device expands and rotates to drive the cleaning device to the position to be cleaned on the channel slope for cleaning. During the cleaning process, the roller shaft of the rotary brush mechanism rotates, and the wire rope brush on the roller shaft rubs the surface of the slope for algae cleaning. During the rotation of the roller shaft, the high-pressure water pipeline supplies high-pressure water to the spray rod and the cavitation jet nozzle to wash the surface of the slope, forming algae water inside the cleaning mechanism. At the same time, the sewage suction pipeline assembly sucks the cleaned algae water mixed slurry into the algae water separation device for algae water separation.

[0013] The specific operation process of step (4) is as follows: ① In the initial state, the intermediate pressing plate is located at the middle position in the front-back direction of the separation tank. The two-way three-way solenoid valve is controlled to connect the main sewage inlet pipe with the first sewage inlet branch pipe. The sewage suction pipeline assembly transports the algae water mixed slurry through the main sewage inlet pipe and the first sewage inlet branch pipe and falls onto the rear side of the intermediate pressing plate through the first water inlet hole. The sewage of the algae water mixed slurry enters the first water filtering funnel through the filtration of the first filter plate under the action of gravity; ②When the liquid level of the algae-water mixture reaches a certain height, the conveyance of the algae-water mixture to the rear side of the middle pressing plate is stopped. The two-position three-way solenoid valve controls the communication between the main sewage inlet pipe and the second sewage inlet branch pipe. The algae-water mixed slurry passes through the main sewage inlet pipe and the second sewage inlet branch pipe and falls onto the front side of the middle pressing plate through the second water inlet hole. At the same time, the two hydraulic drive motors rotate forward, synchronously driving the gears on the same side to move backward on the racks. The middle pressing plate pushes the algae on the first water filtering funnel backward, causing the algae to be squeezed between the middle pressing plate and the rear pressing plate. As the first damping spring is compressed, the extrusion force on the algae becomes greater and greater, and the water contained in the algae will still be squeezed out. The sewage falls onto the diversion inclined plate at the bottom of the first algae loading tank and is collected at the water outlet to be discharged from the first algae loading tank; ③The middle pressing plate continues to move backward, pushing the rear pressing plate to continuously move backward. During the backward movement of the rear pressing plate, under the action of the first wedge portion and the third wedge portion, the first vertical baffle moves downward to compress the first return spring until the rear pressing plate moves to the rear side of the first vertical baffle. At this time, the first vertical baffle returns upward to its original position under the action of the first return spring; ④Then the hydraulic drive motors rotate in the reverse direction. The hydraulic drive motors drive the middle pressing plate to move forward. The rear pressing plate is blocked by the first vertical baffle, and the algae between the middle pressing plate and the rear pressing plate are no longer under extrusion force and naturally fall into the first algae loading tank. While the hydraulic drive motors drive the middle pressing plate to move forward and the rear pressing plate is blocked by the first vertical baffle, the first hydraulic telescopic cylinder pushes the second wedge block forward. The second wedge block presses down on the seventh wedge surface of the first mounting hole to make the first vertical baffle move downward again. The rear side of the upper end of the first vertical baffle disengages from the front side of the lower end of the rear pressing plate, and the rear pressing plate slowly returns forward to its original position under the action of the first damping spring; ⑤The two hydraulic drive motors rotate in the reverse direction, synchronously driving the gears on the same side to move forward on the racks, causing the middle pressing plate to continuously move forward. When the middle pressing plate moves to its original position, the two-position three-way solenoid valve controls the main sewage inlet pipe to communicate with the first sewage inlet branch pipe again. The algae-water mixed slurry passes through the main sewage inlet pipe and the first sewage inlet branch pipe and falls onto the front side of the middle pressing plate through the first water inlet hole. At the same time, the hydraulic drive motors continuously drive the middle pressing plate to move forward, causing the algae to be squeezed between the middle pressing plate and the front pressing plate. As the second damping spring is compressed, the extrusion force on the algae becomes greater and greater, and the water contained in the algae will still be squeezed out. The sewage falls onto the diversion inclined plate at the bottom of the second algae loading tank and is collected at the water outlet to be discharged from the second algae loading tank; ⑥The middle pressing plate continues to move forward, pushing the front pressing plate to continuously move forward. During the forward movement of the front pressing plate, under the action of the second wedge portion and the fourth wedge portion, the second vertical baffle moves downward to compress the second return spring until the front pressing plate moves to the front side of the second vertical baffle. At this time, the second vertical baffle returns to its original position under the action of the second return spring; ⑦Next, the hydraulic drive motor rotates forward. The hydraulic drive motor drives the middle pressing plate to move backward, while the front pressing plate is blocked by the second vertical baffle. The algae between the middle pressing plate and the front pressing plate are no longer under extrusion pressure and naturally fall into the second algae storage tank. While the middle pressing plate moves backward and the front pressing plate is blocked by the second vertical baffle, the second hydraulic telescopic cylinder extends, pushing the fourth wedge block to move backward. The fourth wedge block presses down the third wedge block to make the second vertical baffle move downward again. The front pressing plate slowly returns to its original position backward under the action of the second damping spring; ⑧Keep repeating steps ② to ⑦ until the treatment of the algae is completed.

[0014] Step (5) is specifically as follows: The solenoid valve is activated, so that the inside of the suction cup assembly is communicated with the external atmosphere through the connecting air holes, and the atmospheric pressure is restored inside the suction cup assembly. Furthermore, the outer rubber ring and the lower end of the inner rubber ring at the lower end of the suction cup assembly no longer adsorb the road surface. Then all the first lifting hydraulic cylinders and the second lifting hydraulic cylinders are activated again, driving the suction cup assembly to move upward. After the truck travels forward a certain distance, the certain distance is the length in the front-back direction for the mechanical telescopic arm device to control the cleaning device to clean the channel slope; Then keep repeating steps (2), (3) and (4) until the environmental protection treatment of the epiphytic algae on the channel slope is completed.

[0015] The vacuum pipeline assembly arranged on the side of the mechanical telescopic arm device in this application is different from the traditional method of using a reel device to wind the vacuum conveying pipeline. In the present invention, steel pipe sleeves are used to achieve the steam-water seal and movement expansion of the vacuum pipeline system. The manipulator adopts a three-section telescopic arm structure, and three pipelines are also arranged on the side of the telescopic arm. The large-diameter pipeline is arranged at the lower part of the telescopic arm, and the small-diameter pipeline is arranged at the upper part of the telescopic arm. There is a certain overlap margin (overlapping part) between the large and small diameters. The telescopic vacuum pipeline realizes synchronous expansion and contraction under the traction of the telescopic arm. At the same time, the steam-water seal is realized by using the fit clearance, and a small amount of leakage is avoided from overflowing due to the inclined arrangement during operation, so as to ensure the reliable seal of the steam-water under the condition of moving expansion and contraction. One end of the inner pipe of the vacuum pipeline assembly with synchronous expansion and contraction function under the condition of multiple-section telescopic arms is connected to the storage tank through a sewage suction rubber hose, and one end of the outer pipe is connected to the sewage suction pipeline of the cleaning trolley through a sewage suction rubber hose.

[0016] The negative pressure adsorption positioning anti-rollover device of this application has good stability and safety, and can effectively prevent the vehicle from skidding and avoid the phenomenon of poor cleaning effect caused by shaking during the cleaning process.

[0017] The cooperation of the middle pressing plate, the front pressing plate and the rear pressing plate of the algae-water separation device in this application squeezes and separates the algae, and realizes reciprocating algae-water separation by using the cooperation of the corresponding wedge surfaces, which has the characteristics of high separation efficiency and good separation effect, and greatly improves the algae-water separation efficiency and separation effect.

[0018] The vacuum pipeline system of the present application can achieve actions such as pipeline telescoping, amplitude variation, and rotation, so that the cleaning trolley device can meet the requirements of different channel slope operation conditions; the vacuum pipeline system with synchronous telescoping function under the condition of multiple telescopic arms is flexible in telescoping, has high operation efficiency, and has good sealing effect, making the cleaning process more environmentally friendly.

[0019] In summary, the operation of the present invention is convenient, overcoming the defects of the existing attached algae removal technology, such as the algae cannot be eradicated, the operation efficiency is low, and secondary pollution is easily generated, and greatly improving the removal efficiency.

[0028] The negative pressure adsorption positioning anti-rollover device 109 is arranged on the opposite side of the working side of the heavy truck 1, and includes a mounting channel steel 73 arranged in the front-back direction. A plurality of suction cup assemblies 74 are connected to the bottom of the mounting channel steel 73, and a plurality of lifting assemblies 75 are arranged on the top of the mounting channel steel 73. The bottom end of the lifting assembly 75 is connected to the mounting channel steel 73 through a lifting seat, and the top end of the lifting assembly 75 is connected to the vehicle chassis; The lifting seat includes a first vertical plate 88 and a second vertical plate 89. Corresponding first plate holes and second plate holes are respectively arranged on the first vertical plate 88 and the second vertical plate 89. The lifting assembly 75 includes a first lifting hydraulic cylinder 90 and a second lifting hydraulic cylinder 91. The first lifting hydraulic cylinder 90 and the second lifting hydraulic cylinder 91 are installed between the first vertical plate 88 and the second vertical plate 89 through corresponding installation connecting pins; The suction cup assembly 74 includes a fixed mounting plate 76. An outer positioning ring 77 and an inner positioning ring 78 are arranged at the bottom of the fixed mounting plate 76. A ring-shaped positioning groove with a downward opening is formed between the outer positioning ring 77 and the inner positioning ring 78. An outer rubber ring 79 and an inner rubber ring 80 are installed in the ring-shaped positioning groove. A ring-shaped sealing groove is formed between the outer rubber ring 79 and the inner rubber ring 80. A ring-shaped sealing block 81 is installed in the ring-shaped sealing groove. A plurality of countersunk bolts 82 are arranged on the ring-shaped sealing block 81 along the circumferential direction. The ring-shaped sealing block 81 is connected to the bottom of the fixed mounting plate 76 through the countersunk bolts 82. A through hole is arranged at the central part of the fixed mounting plate 76. A suction pipeline 83 is installed in the through hole. The suction pipeline 83 is connected to a suction pump. A filter screen 84 is arranged at the lower end of the through hole. A connecting air hole 85 is arranged on one side of the through hole. A solenoid valve 86 is arranged at the upper end of the connecting air hole 85; A fixed connecting rod 87 is arranged between the fixed mounting plate 76 and the mounting channel steel 73. The top end of the fixed connecting rod 87 is connected to the mounting channel steel 73, and the bottom end of the fixed connecting rod 87 is connected to the lower surface of the fixed mounting plate 76. A blowing pipeline 92 is arranged on the side surface of the fixed mounting plate 76. The blowing pipeline 92 is connected to an air supply pump; The inner side of the longitudinal section of the outer positioning ring 77 is inclined outward from low to high, and the outer side of the longitudinal section of the inner positioning ring 78 is inclined inward from low to high. The longitudinal section of the ring-shaped positioning groove is an isosceles trapezoid with a longer upper base and a shorter lower base. The longitudinal sections of the ring-shaped sealing block 81 and the upper half of the longitudinal section of the ring-shaped sealing groove are both isosceles trapezoids with a shorter upper base and a longer lower base. The outer rubber ring 79 and the inner rubber ring 80 are pressed between the outer positioning ring 77 and the inner positioning ring 78 through the countersunk bolts 82, which has the advantages of convenient installation, easy disassembly, and reliable positioning connection. Ring-shaped circular channels 93 are arranged inside both the outer rubber ring 79 and the inner rubber ring 80. This channel can effectively improve the elasticity of the rubber ring. When the lower ring surfaces of the outer rubber ring 79 and the inner rubber ring 80 adsorb the road surface, they have greater compression and deformation amounts, increasing the adsorption force. At the same time, it can also play a buffering role when the outer rubber ring 79 and the inner rubber ring 80 touch the ground.

[0029] The specific operation process of step (2) is as follows: The heavy truck 1 drives forward along the road on the bank of the channel. During the driving process, the air blowing pipe 92 on the outer cylindrical surface of the outer positioning ring 77 blows air to the ground under the air supply of the air supply pump, dispersing the dust and small particles on the ground. After the heavy truck 1 drives to the working position, it parks, turns off the air supply pump, and starts all the first lifting hydraulic cylinders 90 and the second lifting hydraulic cylinders 91. The first lifting hydraulic cylinders 90 and the second lifting hydraulic cylinders 91 synchronously extend to drive all the suction cup assemblies 74 to descend. When the outer rubber ring 79 and the inner rubber ring 80 of the suction cup assembly 74 contact the road surface, the suction pump is started, and air is sucked through the suction pipe 83 to form a negative pressure in the cavity between the fixed mounting plate 76, the inner rubber ring 80 and the ground, thereby tightly sucking the suction cup assembly 74 to the road surface. Since the negative pressure adsorption positioning anti-rollover device 109 is arranged on the left side of the heavy truck 1, that is, on the side far from the channel slope, the heavy truck 1 is positioned by negative pressure adsorption on the road surface, thereby preventing the heavy truck 11 from tipping to the left during the operation of the mechanical telescopic boom device 4 and the cleaning device 95 in the cantilever state.

[0030] The specific operation process of step (3) is as follows: The mechanical telescopic boom device 4 extends and retracts to drive the cleaning device 95 to the position to be cleaned on the channel slope for cleaning. During the cleaning process, the roller shaft 15 of the brush roller mechanism rotates, and the wire rope brush 16 on the roller shaft 15 rubs against the ground for algae cleaning. During the rotation of the roller shaft 15, the high-pressure water pipe supplies high-pressure water to the spray rod 19 and the cavitation jet nozzle 20 to wash the ground, forming algae water inside the cleaning mechanism. At the same time, the sewage suction pipe assembly sucks the cleaned algae water into the algae water separation device 3 for algae water separation.

[0031] The specific operation process of step (4) is as follows: ① In the initial state, the intermediate pressing plate 51 is located at the middle position in the front-rear direction of the separation tank 44. The two-position three-way solenoid valve 104 is controlled to connect the main sewage inlet pipe 103 with the first sewage inlet branch pipe 101. The sewage suction pipe assembly conveys the algae water mixed slurry through the main sewage inlet pipe 103 and the first sewage inlet branch pipe 101 and falls onto the rear side of the intermediate pressing plate 51 through the first water inlet hole 55. The sewage of the algae water mixed slurry enters the first water filtering funnel 46 through the filtration of the first filter plate 48 under the action of gravity; ②When the liquid level of the algae-water mixture reaches a certain height, the conveyance of the algae-water mixture to the rear side of the intermediate pressing plate 51 is stopped. The two-position three-way solenoid valve 104 controls the communication between the main sewage inlet pipe 103 and the second sewage inlet branch pipe 102. The algae-water mixed slurry passes through the main sewage inlet pipe 103 and the second sewage inlet branch pipe 102 and falls onto the front side of the intermediate pressing plate 51 through the second water inlet hole 56. At the same time, the two hydraulic drive motors rotate forward, synchronously driving the gears 60 on the same side to move backward on the racks 62. The intermediate pressing plate 51 pushes the algae on the first water filtering funnel 46 backward, causing the algae to be squeezed by the intermediate pressing plate 51 and the rear pressing plate 50. As the first damping spring 53 is compressed, the extrusion force on the algae becomes greater and greater, and the water contained in the algae will still be squeezed out. The sewage falls onto the diversion inclined plate 99 at the bottom of the first algae loading tank 45 and converges at the water outlet 100 to be discharged from the first algae loading tank 45; ③The intermediate pressing plate 51 continues to move backward, pushing the rear pressing plate 50 to continuously move backward. During the backward movement of the rear pressing plate 50, under the action of the first wedge portion and the third wedge portion, the first vertical baffle 67 moves downward to compress the first return spring 63 until the rear pressing plate 50 moves to the rear side of the first vertical baffle 67. At this time, the first vertical baffle 67 returns to its original position under the action of the first return spring 63; ④Then the hydraulic drive motors rotate in the reverse direction. The hydraulic drive motors drive the intermediate pressing plate 51 to move forward. The rear pressing plate 50 is blocked by the first vertical baffle 67, and the algae between the intermediate pressing plate 51 and the rear pressing plate 50 are no longer under extrusion force and naturally fall into the first algae loading tank 45. While the hydraulic drive motors drive the intermediate pressing plate 51 to move forward and the rear pressing plate 50 is blocked by the first vertical baffle 67, the first hydraulic telescopic cylinder 69 pushes the second wedge block 108 to move forward. The second wedge block 108 presses down on the seventh wedge surface of the first mounting hole 105 to cause the first vertical baffle 67 to move downward again. The rear side of the upper end of the first vertical baffle 67 disengages from the front side of the lower end of the rear pressing plate 50, and the rear pressing plate 50 slowly returns to its original position forward under the action of the first damping spring 53; ⑤The two hydraulic drive motors rotate in the reverse direction, synchronously driving the gears 60 on the same side to move forward on the racks 62, causing the intermediate pressing plate 51 to continuously move forward. When the intermediate pressing plate 51 moves to its original position, the two-position three-way solenoid valve 104 controls the main sewage inlet pipe 103 to communicate with the first sewage inlet branch pipe 101 again. The algae-water mixed slurry passes through the main sewage inlet pipe 103 and the first sewage inlet branch pipe 101 and falls onto the front side of the intermediate pressing plate 51 through the first water inlet hole 55. At the same time, the hydraulic drive motors continuously drive the intermediate pressing plate 51 to move forward, causing the algae to be squeezed by the intermediate pressing plate 51 and the front pressing plate 52. As the second damping spring 54 is compressed, the extrusion force on the algae becomes greater and greater, and the water contained in the algae will still be squeezed out. The sewage falls onto the diversion inclined plate 99 at the bottom of the second algae loading tank 96 and converges at the water outlet 100 to be discharged from the second algae loading tank 96; ⑥The middle pressing plate 51 continues to move forward, pushing the front pressing plate 52 to continuously move forward. During the forward movement of the front pressing plate 52, under the action of the second wedge portion and the fourth wedge portion, the second vertical baffle 68 moves downward to compress the second return spring 64 until the front pressing plate 52 moves to the front side of the second vertical baffle 68. At this time, the second vertical baffle 68 returns to its original position under the action of the second return spring 64; ⑦Then the hydraulic drive motor rotates forward. The hydraulic drive motor drives the middle pressing plate 51 to move backward while the front pressing plate 52 is blocked by the second vertical baffle 68. The algae between the middle pressing plate 51 and the front pressing plate 52 are no longer under extrusion pressure and naturally fall into the second algae loading box 96. While the middle pressing plate 51 moves backward and the front pressing plate 52 is blocked by the second vertical baffle 68, the second hydraulic telescopic cylinder 70 extends, pushing the fourth wedge block to move backward. The fourth wedge block presses down the third wedge block to make the second vertical baffle 68 move downward again. The front pressing plate 52 slowly returns to its original position backward under the action of the second damping spring 54; ⑧Keep repeating steps ② to ⑦ until the treatment of the algae is completed.

[0032] Step (5) is specifically as follows: The solenoid valve 86 is activated, so that the inside of the suction cup assembly 74 is communicated with the external atmosphere through the connecting air hole 85. The inside of the suction cup assembly 74 restores atmospheric pressure, and further makes the outer rubber ring 79 and the lower end of the inner rubber ring 80 at the lower end of the suction cup assembly 74 no longer adsorb the road surface. Then all the first lifting hydraulic cylinders 90 and the second lifting hydraulic cylinders 91 are activated again, driving the suction cup assembly 74 to move upward. After the truck 1 travels forward a certain distance, the certain distance is the length in the front-back direction for the mechanical telescopic arm device 4 to control the cleaning device 95 to clean the channel slope. Then keep repeating steps (2), (3) and (4) until the environmental protection treatment of the algae growing on the channel slope is completed. Repeating the action of step (2) can perform positioning again.

[0033] The vacuum pipeline assembly arranged on the side of the mechanical telescopic arm device 4 in this application is different from the traditional method of winding the vacuum conveying pipeline with a reel device. In this invention, steel pipe socket joints are used to achieve the steam-water seal and the movement and telescoping of the vacuum pipeline system. The manipulator adopts a three-section telescopic arm structure, and three pipelines are also arranged on the side of the telescopic arm. The large-diameter pipeline is arranged at the lower part of the telescopic arm, and the small-diameter pipeline is arranged at the upper part of the telescopic arm. A certain overlap margin (overlapping part) is used between the large and small diameters. The telescopic vacuum pipeline realizes synchronous telescoping under the traction of the telescopic arm. At the same time, the steam-water seal is achieved by using the fitting clearance, and a small amount of leakage is realized and overflow is avoided due to the inclined arrangement during operation, so as to ensure the reliable seal of steam and water under the condition of moving and telescoping. One end of the inner pipe 31 of the vacuum pipeline assembly with synchronous telescoping function under the condition of multi-section telescopic arms is connected to the storage tank through a sewage suction rubber hose, and one end of the outer pipe 33 is connected to the sewage suction pipeline of the cleaning trolley through a sewage suction rubber hose. The negative pressure adsorption positioning anti-rollover device 109 of this application has good stability and safety, and can effectively prevent the vehicle from skidding and avoid the phenomenon of poor cleaning effect caused by shaking during the cleaning process. The cooperation of the intermediate pressing plate 51, the front pressing plate 52 and the rear pressing plate 50 of the algae-water separation device 3 in this application squeezes and separates the algae, and realizes reciprocating algae-water separation by using the cooperation of the corresponding wedge-shaped surfaces, which has the characteristics of high separation efficiency and good separation effect, and greatly improves the algae-water separation efficiency and separation effect. The vacuum pipeline system of this application can realize actions such as pipeline telescoping, luffing, and slewing, so that the cleaning trolley device can meet the requirements of different channel slope operation conditions; the vacuum pipeline system with synchronous telescoping function under the condition of multi-section telescopic arms is flexible in telescoping, has high operation efficiency, and has a good sealing effect, making the cleaning process more environmentally friendly. This invention is convenient to operate, overcomes the defects of the existing attached algae removal technology, such as the algae cannot be eradicated, the operation efficiency is low, and secondary pollution is easily generated, and greatly improves the removal efficiency.

7. The environmentally friendly treatment method for algae growth on channel slopes according to claim 6 is characterized by: The specific operation process of step (2) is as follows: the truck moves forward along the road on the bank of the channel. During the driving process, the air blowing pipe on the outer circular surface of the outer positioning ring blows air toward the ground under the air supply action of the air pump to blow away the dust and small particles on the ground. After the truck reaches the working position, it parks, the air pump is turned off, and all the first lifting hydraulic cylinders and the second lifting hydraulic cylinders are started. The first lifting hydraulic cylinders and the second lifting hydraulic cylinders are synchronously extended to drive all the suction cup assemblies to descend. When the outer rubber ring and the inner rubber ring of the suction cup assembly contact the road surface, the suction pump is started, and air is sucked through the suction pipe to form a negative pressure in the cavity between the fixed mounting plate, the inner rubber ring and the ground, thereby causing the suction cup assembly to tightly absorb the road surface. Since the negative pressure adsorption positioning anti-rollover device is arranged on the left side of the truck, that is, away from the side of the channel slope, the negative pressure adsorption road surface positions the truck, thereby preventing the mechanical telescopic arm device and the cleaning device in the cantilever state from tipping over to the left during operation.

8. The environmentally friendly treatment method for algae growth on channel slopes according to claim 7 is characterized by: The specific operation process of step (3) is as follows: the mechanical telescopic arm device is extended and rotated to drive the cleaning device to the channel slope to be cleaned position for cleaning. During the cleaning process, the roller shaft of the roller brush mechanism rotates, and the wire rope brush on the roller shaft rubs against the slope surface to clean the algae. During the rotation of the roller shaft, the high-pressure water pipeline provides high-pressure water to the spray rod and the cavitation jet nozzle to flush the slope surface, forming algae water inside the cleaning mechanism. At the same time, the sewage suction pipe assembly sucks the cleaned algae-water mixed slurry into the algae-water separation device for algae-water separation.

9. The environmentally friendly treatment method for algae growth on channel slopes according to claim 8, characterized in that: The specific operation process of step (4) is as follows: ① In the initial state, the middle pressure plate is located in the middle position of the separation box in the front-to-back direction. The sewage inlet main pipe is connected to the first sewage inlet branch pipe through the two-position three-way solenoid valve. The sewage suction pipeline assembly transports the algae-water mixed slurry through the sewage inlet main pipe and the first sewage inlet branch pipe through the first water inlet hole to the rear side of the middle pressure plate. The sewage of the algae-water mixed slurry is filtered by the first filter plate under the action of gravity and enters the first water filter funnel; ② When the liquid level of the algae-water mixture reaches a certain height, the algae-water mixture is stopped from being transported to the rear side of the middle pressure plate. The two-position three-way solenoid valve controls the sewage inlet main pipe to be connected with the second sewage inlet branch pipe. The algae-water mixed slurry passes through the sewage inlet main pipe and the second sewage inlet branch pipe and falls to the front side of the middle pressure plate through the second water inlet hole. At the same time, the two hydraulic drive motors rotate forward, synchronously driving the gears on the same side to move backward on the rack. The middle pressure plate pushes the algae on the first water filter funnel backward, so that the algae are squeezed by the middle pressure plate and the rear pressure plate. As the first damping spring is compressed, the extrusion force on the algae becomes greater and greater, and the water contained in the algae will still be squeezed out. The sewage falls into the guide inclined plate at the bottom of the first algae box and gathers at the outlet to be discharged from the first algae box. ③ The middle pressure plate continues to move backward, pushing the rear pressure plate to continue to move backward. During the rear pressure plate's backward movement, under the action of the first wedge-shaped portion and the third wedge-shaped portion, the first vertical baffle moves downward to compress the first return spring until the rear pressure plate moves to the rear side of the first vertical baffle. At this time, the first vertical baffle returns to its original position upward under the action of the first return spring; ④ Then the hydraulic drive motor rotates in the opposite direction, and the hydraulic drive motor drives the middle pressure plate to move forward, and the rear pressure plate is supported by the first vertical baffle plate. The algae between the middle pressure plate and the rear pressure plate are no longer subjected to the squeezing force and naturally fall into the first algae box. While the hydraulic drive motor drives the middle pressure plate to move forward and the rear pressure plate is supported by the first vertical baffle plate, the first hydraulic telescopic cylinder pushes the second wedge block to move forward, and the second wedge block presses down the seventh wedge surface of the first mounting hole to move the first vertical baffle plate downward again. The rear side surface of the upper end of the first vertical baffle plate is separated from the front side surface of the lower end of the rear pressure plate, and the rear pressure plate slowly returns to its original position forward under the action of the first damping spring; ⑤ The two hydraulic drive motors rotate in opposite directions, synchronously driving the gear on the same side to move forward on the rack, so that the middle pressure plate continues to move forward. When the middle pressure plate moves to its original position, the two-position three-way solenoid valve controls the sewage inlet main pipe to be connected with the first sewage inlet branch pipe again. The algae-water mixed slurry passes through the sewage inlet main pipe and the first sewage inlet branch pipe and falls to the front side of the middle pressure plate through the first water inlet hole. At the same time, the hydraulic drive motor continuously drives the middle pressure plate forward, so that the algae are squeezed by the middle pressure plate and the front pressure plate. As the second damping spring is compressed, the extrusion force on the algae becomes greater and greater, and the water contained in the algae will still be squeezed out. The sewage falls into the guide inclined plate at the bottom of the second algae box and is collected at the outlet to be discharged from the second algae box. ⑥ The middle pressure plate continues to move forward, pushing the front pressure plate to continue to move forward. During the forward movement of the front pressure plate, under the action of the second wedge-shaped portion and the fourth wedge-shaped portion, the second vertical baffle moves downward to compress the second return spring until the front pressure plate moves to the front side of the second vertical baffle. At this time, the second vertical baffle returns to its original position under the action of the second return spring; ⑦ Then the hydraulic drive motor rotates forward, the hydraulic drive motor drives the middle pressure plate to move backward while the front pressure plate is supported by the second vertical baffle plate, the algae between the middle pressure plate and the front pressure plate are no longer subjected to the squeezing force, and naturally fall into the second algae box, while the middle pressure plate moves backward while the front pressure plate is supported by the second vertical baffle plate, the second hydraulic telescopic cylinder extends, pushing the fourth wedge block to move backward, the fourth wedge block presses down the third wedge block to make the second vertical baffle plate move downward again, and the front pressure plate slowly returns to its original position backward under the action of the second damping spring; ⑧ Repeat steps ② to ⑦ continuously until the algae treatment is completed.

10. The environmentally friendly treatment method for algae growth on channel slopes according to claim 9, characterized in that: Step (5) is specifically as follows: the solenoid valve is activated to connect the interior of the suction cup assembly to the outside atmosphere through the connecting air hole, and the atmospheric pressure is restored inside the suction cup assembly, so that the outer rubber ring and the lower end of the inner rubber ring at the lower end of the suction cup assembly no longer adhere to the road surface, and then all the first lifting hydraulic cylinders and the second lifting hydraulic cylinders are activated again to drive the suction cup assembly to move upward, and the truck moves forward for a certain distance, wherein the certain distance is the length in the front-to-back direction of the mechanical telescopic arm device controlling the cleaning device to perform the cleaning operation on the channel slope; then steps (2), (3) and (4) are continuously repeated until the environmentally friendly treatment of the algae growing on the channel slope is completed.
