Description

Technical Field

[0001] This invention belongs to the field of hydropower station water diversion channel maintenance technology, specifically relating to a water diversion channel maintenance operation equipment and its usage method. Background Technology

[0002] The intake channel of the hydropower station's generating units is a concrete structure. Over time, the flow surface has suffered erosion and damage due to the scouring effect of water flow, sand, and other debris. Therefore, repair work on the intake channel is a regular part of the annual hydraulic engineering maintenance during the dry season. The hydropower station's intake channel is typically divided into three sections: an upper bend, a vertical section, and a lower bend. Its total horizontal length exceeds 200m, the elevation difference is greater than 150m, and the channel diameter is greater than 8m. The intake channel space is relatively enclosed, and the equipment entry space is narrow. This not only limits the use of conventional lifting equipment on-site but also makes it difficult to maintain stability in a large-diameter channel with a high vertical drop, resulting in significant difficulties for personnel to approach for inspection and for high-altitude repair work.

[0003] Currently, the overall overhaul of the water intake channel of the hydropower station unit only involves the inspection and repair of the bottom plate of the horizontal section of the channel. The vertical section is inspected and recorded using drones. However, drones cannot carry large maintenance equipment, making it impossible to carry out detailed repair work. Furthermore, due to the difficulty of operating drones while flying in the pipeline, the maintenance scope per unit time is small. This not only fails to achieve full coverage of channel maintenance but also has a significant impact on work efficiency and overall maintenance quality.

[0004] Therefore, it is necessary to provide a water diversion channel maintenance equipment and its usage method to reduce the limiting effect of the water diversion channel on the maintenance equipment, improve the applicability of the water diversion channel maintenance equipment, increase work efficiency, increase the maintenance coverage area of ​​the water diversion channel, and improve the quality of maintenance work. Summary of the Invention

[0005] To overcome the problems in the background art, this invention proposes a water diversion channel maintenance equipment and its usage method. Through modular design, the equipment is easily assembled within the water diversion channel, thereby reducing the limiting effect of the water diversion channel on the maintenance equipment and improving its applicability. The lifting effect of the mobile chassis on the manned operation mechanism enables manual maintenance of the vertical section of the water diversion channel, and allows multiple maintenance workers to perform maintenance simultaneously, improving work efficiency, increasing the maintenance coverage area of ​​the water diversion channel, and enhancing maintenance quality.

[0020] In another aspect, the present invention provides a method for using the above-mentioned water diversion channel maintenance equipment, the method comprising the following steps: (1) Assemble the mobile chassis, personnel passage, and climbing operation mechanism in the 200 level section of the water diversion channel; (2) Release the steel cable wound on the winch 210 and connect the steel cable to the gantry at the front end of the water diversion channel 200. After the connection is fixed, adjust the rotation direction of the winch 210 to tighten the steel cable and then stop the winch 210. (3) Drill holes at a predetermined position at the top of the horizontal section of the water diversion channel 200 using a regular telescopic ladder and install the first pulley group 203. After the first pulley group 203 is installed, start the large winch 201 and the small winch 205 to release the equipment traction steel cable 202 and the personnel traction steel cable 204. Wrap the equipment traction steel cable 202 and the personnel traction steel cable 204 around the first pulley group 203 and observe the length of the equipment traction steel cable 202 and the personnel traction steel cable 204 so that they can wrap around the second pulley group. (4) Start the winch 210 to release the steel cable, and at the same time start the triangular track wheel 212 to cooperate with the speed of the winch 210 to release the steel cable, so that the mobile chassis slowly moves towards the vertical section of the water diversion channel 200 and pushes the personnel passage and the climbing operation mechanism to move towards the vertical section of the water diversion channel 200. Observe the position of the mobile chassis, personnel passage and climbing operation mechanism. When the climbing operation mechanism approaches the predetermined installation position of the second pulley block, control the triangular track wheel 212 to slow down the movement speed and make a fine adjustment to the position of the climbing operation mechanism. After completion, control the triangular track wheel 212 to stop moving, and at the same time the personnel passage and the climbing operation mechanism also stop moving. Adjust the rotation direction of the winch 210 again to tighten the steel cable to prevent the equipment from falling. (5) Start the swing arm 215 to lower the fixing plate 211 onto the inner wall of the water diversion channel 200. The workers fix the fixing plate 211 to the inner wall of the water diversion channel 200 with expansion bolts. Then, the workers enter the personnel passage and reach the anchor support base 225 through the personnel passage. The bottom end of the anchor support base 225 is anchored to the inner wall of the water diversion channel 200. Then, the workers turn the handwheel 220 to unfold the climbing ladder 224. When the working platform 223 at the top of the climbing ladder 224 rotates to the predetermined installation position of the second pulley group 208, the handwheel 220 stops rotating and the adjusting screw 221 is tightened. The nut is locked to tighten the adjusting screw 221 and the U-shaped support plate 226, thereby locking the climbing staircase 224. Then, the reduction motor 247 is started to push out the telescopic section of the telescopic arm 222. When the rubber pad 243 at the end of the telescopic section of the telescopic arm 222 abuts against the inner wall of the water diversion channel 200, the reduction motor 247 is stopped. Then, a worker climbs to the top of the climbing staircase 224 and anchors the telescopic arm 222 to the inner wall of the water diversion channel 200. After completion, the work platform 223 is leveled and the fixing rod 248 is fixed to the screw hole at the appropriate position on the upper surface of the telescopic arm 222. (6) The staff went up to the work platform 223, drilled holes in the inner wall of the water diversion channel 200 and installed the second pulley group 208. After the second pulley group 208 was installed, the large winch 201 and the small winch 205 were started again to release the equipment traction steel cable 202 and the personnel traction steel cable 204. The equipment traction steel cable 202 and the personnel traction steel cable 204 were bypassed around the second pulley group 208. Then the staff returned to the bottom of the climbing work mechanism and returned to the mobile chassis through the personnel passage. The large winch 201 and the small winch 205 were started again to continue to release the equipment traction steel cable 202 and the personnel traction steel cable 204. At this time, the equipment traction steel cable 202 and the personnel traction steel cable 204 extended to the bottom of the vertical section of the water diversion channel 200 by gravity. (7) During the process of releasing the equipment traction cable 202 and the personnel traction cable 204 to the bottom of the vertical section of the water diversion channel 200, the personnel at the bottom of the vertical section of the water diversion channel 200 simultaneously assemble the personnel-carrying operation mechanism. When the equipment traction cable 202 and the personnel traction cable 204 reach the bottom of the vertical section of the water diversion channel 200, the large winch 201 and the small winch 205 are stopped. After the personnel securely connect the equipment traction cable 202 to the personnel-carrying operation mechanism, the second large winch 201-2 is started first to wind up the second equipment traction cable 202-2, raising the mother basket to the maintenance operation area. After it is in place, the second large winch is stopped. After the winch 201-2 is activated, the personnel responsible for the maintenance of the inner wall of the water diversion channel 200 enter the sub-hoisted basket and connect the personnel traction cable 204 to themselves. The first large winch 201-1 is started to wind up the first equipment traction cable 202-1, and the sub-hoisted basket is raised to the same level as the mother basket. Then the first large winch 201-1 is stopped. Next, the lower guardrail 236 of the sub-hoisted basket is opened, and the personnel enter the mother basket. The personnel traction cable 204 is wound up until it can hold the maintenance personnel without affecting their movement. Then the small winch 205 is stopped, and the maintenance personnel carry out maintenance work on the inner wall of the water diversion channel 200.

[0021] The beneficial effects of this invention are: 1. By using the water diversion channel maintenance equipment of the present invention, it is possible to inspect the vertical section of the water diversion channel and repair it in a timely manner when problems are found, thereby increasing the coverage area of ​​the water diversion channel inner wall maintenance work, improving work efficiency and maintenance quality.

[0022] 2. This invention uses a turntable connected to a base plate for rotation. By activating different triangular track wheels, the mobile chassis can move forward, backward, left, and right within the pipeline. During position adjustment, unnecessary displacement can be reduced, facilitating position adjustment of the mobile chassis while maintaining high stability. This reduces unnecessary forces when the mobile chassis lifts the personnel-carrying mechanism, lowers the wear and tear on the equipment's traction cable, extends its service life, and helps reduce costs while improving equipment safety.

[0023] 3. The mobile chassis of this invention uses triangular track wheels as its walking structure, which improves the mobility of the mobile chassis on the inner wall of the water diversion channel.

[0024] 4. Most components of the water diversion channel maintenance equipment of this invention adopt a modular design, which facilitates on-site installation and deployment, has strong adaptability to actual engineering projects, and forms an integrated equipment after on-site installation and deployment, which facilitates unified control of the equipment, improves the overall maintenance work, and enhances the sequential connection between different processes.

[0025] 5. This invention uses a large winch to pull the manned operation mechanism and a small winch to pull the maintenance personnel, separating the maintenance personnel from the manned operation mechanism, dispersing the traction pressure, and eliminating the mutual influence between the maintenance personnel and the manned operation mechanism, thereby improving the safety of the maintenance personnel during the maintenance operation.

[0026] 6. The present invention connects the connecting arm and the frame, and a locking pin is provided between the connecting arms to lock the angle when the hinge point rotates to a suitable angle, thereby enhancing the connection stability and improving safety.

[0027] 7. The climbing operation mechanism of the present invention can be adjusted in angle and telescopically extended, which can be easily adjusted according to the actual working conditions to adapt to different working conditions and improve the applicability of the equipment.

[0028] 8. The manned operation mechanism of the present invention is assembled with high-strength aluminum alloy profiles, which ensures strength while being easy to install, convenient to assemble, and low in maintenance cost.

[0029] 9. The present invention installs support wheels on the main column of the main suspended platform, which provide support for the main suspended platform, preventing the main suspended platform from shifting during movement, reducing unnecessary stress on the equipment traction cable, and avoiding collisions and friction with the water diversion channel wall. This improves the safety and stability of the main suspended platform during movement and also has the function of preventing overturning when bending.

[0030] 10. The manned operation mechanism is equipped with a toolbox to facilitate the storage of tools used during maintenance and to make them easily accessible to maintenance personnel; spotlights are installed on the bottom surface of the umbrella-shaped ring beam to illuminate the maintenance work and reduce maintenance omissions and safety risks caused by low visibility in the water diversion channel.

[0031] 11. The present invention has guardrails installed at relevant locations to protect the staff, and the overall safety of the equipment is high.

[0032] 12. This invention uses multiple small winches to ensure the safety of maintenance personnel, dispersing the number of maintenance personnel pulled by each small winch and improving the reliability of safety assurance.

[0033] 13. This invention adopts a dual system of drive control link and safety protection circuit. When human error or equipment failure occurs, the sensor senses the abnormal state and transmits the signal to the primary PLC control system. The primary PLC control system then takes emergency measures to prevent the equipment from continuing to operate and causing safety accidents, thereby improving the safety of the equipment in emergency situations.

The input terminal of the primary PLC control system is remotely electrically connected to the output terminals of the speed sensor, current and voltage sensor, and steel cable tension sensor to form a safety protection circuit.

[0059] The output terminal of the primary PLC control system is remotely electrically connected to the other input terminal of the drive motor of the large winch 201, small winch 205, winch 210, and triangular track wheel 212. The primary PLC control system has a higher control priority than the secondary PLC system.

[0060] There are two frames 214, located at both ends of the base plate 213. There are eight swing arms 215, with four swing arms 215 connected to each frame 214. The four swing arms 215 on the same frame 214 are divided into two groups, each group containing two swing arms 215. The two groups of swing arms 215 on the same frame 214 are symmetrically arranged with the frame 214 as the axis of symmetry. There are four triangular track wheels 212, with one triangular track wheel 212 installed at each end of each frame 214. Each triangular track wheel 212 is driven by an independent drive motor. There are four small winches 205.

[0061] After the equipment is installed, the steel cable wound on the winch 210 is led out and connected to the gantry of the water diversion channel. The winch 210 is started to tighten the steel cable, creating tension on the mobile chassis. As the mobile chassis pushes the personnel passage and climbing mechanism towards the vertical section of the water diversion channel 200, the mobile chassis, personnel passage, and climbing mechanism are not fixed to the inner wall of the water diversion channel 200. However, some sections of the personnel passage will be located in the curved sections of the water diversion channel 200. At this time, the personnel passage and climbing mechanism will exert their own weight on the water diversion channel. The mobile chassis generates tension. If the mobile chassis is not secured, the mobile chassis, personnel access, and climbing mechanism will slide directly down the curved section of the water diversion channel 200 and eventually fall to the bottom of the vertical section of the water diversion channel 200. At the same time, during the lifting of the personnel-carrying mechanism, the personnel-carrying mechanism will generate tension on the mobile chassis. The tension of the steel cable pulling the mobile chassis can offset part of the tension on the mobile chassis from the personnel-carrying mechanism, thereby reducing the stress on other fixed components and increasing the stability and safety of the equipment operation. Simultaneously, individual control of the triangular track wheels 212 allows for position adjustment of the mobile chassis within the water diversion channel. For example, to adjust the mobile chassis to the left, control the right triangular track wheel 212 of the mobile chassis to rotate in its forward direction, and control the left triangular track wheel 212 of the mobile chassis to rotate in its backward direction, causing the turntable 216 to rotate counterclockwise. During the adjustment process, the mobile chassis can remain stationary. After the mobile chassis has been assembled and connected with the personnel passage and climbing operation mechanism, reducing unnecessary movement of the mobile chassis during position adjustment helps maintain equipment stability. After adjustment, the direction of travel of the triangular track wheels 212 is perpendicular to the axis of the water diversion channel. Then, simultaneously controlling all triangular track wheels 212 to rotate in the forward direction completes the leftward adjustment of the mobile chassis.

[0062] By controlling the movement of the swing arm 215, the fixed plate 211 can be lowered so that it contacts the inner wall of the water diversion channel 200. After the fixed plate 211 is fixed to the inner wall of the water diversion channel 200, the position of the chassis is moved to form a fixed position.

[0063] When human error or equipment malfunction occurs during equipment operation, the speed sensor, voltage and current sensor, and cable tension sensor will detect abnormal data. The sensors will transmit the abnormal data signals to the primary PLC control system. Upon receiving the abnormal data signals, the primary PLC control system will stop the drive motors of the large winch 201, small winch 205, winch 210, and triangular track wheel 212. Since the primary PLC control system has a higher control priority than the secondary PLC control system, when the primary PLC control system controls the equipment, the secondary PLC control system loses control of the equipment. Therefore, when human error or equipment malfunction occurs, the primary PLC control system can stop the equipment to prevent the equipment from continuing to operate and increasing safety risks.

[0064] The personnel passage is composed of several hinged unit passages. Each unit passage includes a U-shaped guardrail 207, a connecting arm 206, and a passage staircase. The bottom surface of the unit passage is formed by the passage staircase. Connecting arms 206 are fixedly installed on both sides of the passage staircase. The ends of the U-shaped guardrail 207 are fixedly connected to the connecting arms 206. The U-shaped guardrail 207 of the same unit passage covers its corresponding passage staircase. The different unit passages are connected by hinges between the connecting arms 206 to form the personnel passage. One end of the connecting arm 206 of the unit passage located at one end of the personnel passage is hinged to the connecting frame 217, and one end of the connecting arm 206 of the unit passage located at the other end of the personnel passage is fixedly connected to the climbing operation mechanism.

[0065] The personnel access provides protection for staff, allowing them to move safely and conveniently within the water diversion channel.

[0066] The connecting arm 206 is provided with a locking pin 218 at the hinge joint between the connecting arm 206 and the connecting frame 217, and the connecting arm 206 of different unit channels.

[0067] The locking pin 218 can be used to tighten the hinge point of two connecting arms at a certain angle, so as to fix the angle between the two connecting arms.

[0068] The climbing mechanism includes an angle adjustment component, a telescopic boom 222, a working platform 223, an anchoring support base 225, and a climbing staircase 224. The anchoring support base 225 includes an inclined section and a horizontal section. The end of the inclined section of the anchoring support base 225 is fixedly connected to a personnel passage, and a staircase is installed on the inclined section of the anchoring support base 225. The angle adjustment component is installed on the horizontal section of the anchoring support base 225 and connected to the climbing staircase 224. The bottom end of the climbing staircase 224 is hinged to the horizontal section of the anchoring support base 225. The top end of the climbing staircase 224 is fixedly connected to the non-telescopic end of the telescopic boom 222. The working platform 223 is hinged to the inner side of the non-telescopic section of the telescopic boom 222. The bottom of the working platform 223 is hinged to one end of the fixed rod 248. The other end of the fixed rod 248 is fixedly connected to the upper surface of the non-telescopic section of the telescopic arm 222 by bolts. Several bolt holes are opened on the upper surface of the non-telescopic section of the telescopic arm 222. A motor base 245 is fixedly connected inside the telescopic arm 222. A reduction motor 247 is horizontally mounted at the front end of the motor base 245. The front end of the reduction motor 247 is horizontally fixedly connected to a screw 246 through a spline groove. The connecting screw 246 passes vertically through the top plate 244 and cooperates with the screw hole in the center of the top plate 244 to form a screw drive. The top plate 244 is fixedly connected to the bottom end of the telescopic section of the telescopic arm 222. A rubber pad 243 is fixedly connected to the other end of the telescopic section of the telescopic arm 222.

[0069] Guardrails are welded and fixed to the anchor support base 225, the climbing stairs 224, and the working platform 223.

[0070] The geared motor 247 is equipped with a speed sensor and a current and voltage sensor. Different input terminals of the geared motor 247 are remotely electrically connected to the primary PLC control system and the secondary PLC control system, respectively.

[0071] The angle adjustment assembly includes a screw seat 219, a handwheel 220, an adjusting screw 221, a U-shaped support plate 226, and a screw slide buckle 227. The U-shaped support plate 226 is fixedly installed on the horizontal section of the anchor support base 225. A slot is opened on the upper part of the bottom surface of the U-shaped support plate 226. The screw slide buckle 227 is slidably installed in the U-shaped slot. The screw seat 219 is fixedly installed on both sides of the climbing stairs 224. The handwheel 220 is installed at one end of the adjusting screw 221. The other end of the adjusting screw 221 passes through the slot and is rotatably sleeved with the screw seat 219 via the screw slide buckle 227. The adjusting screw 221 is threadedly connected to the screw slide buckle 227. The adjusting screw 221 is locked to the U-shaped support plate 226 by a nut.

[0072] The anchoring support base 225 is fixed to the inner wall of the water diversion channel through anchoring, making it more stable. Workers can climb from the anchoring support base 225 to the working platform 223 via the climbing ladder 224, and a second pulley block 208 is installed on the working platform 223. The guardrails provide protection for workers moving or working on the climbing mechanism. After the telescopic boom 222 is extended, the end of its telescopic section can abut against the inner wall of the water diversion channel 200. Then, the end of the telescopic section of the telescopic boom 222 is fixed to the inner wall of the water diversion channel 200 through anchoring, so that the inner wall of the water diversion channel 200 supports the climbing ladder 224, further improving the stability of the climbing mechanism.

[0073] By gripping the handwheel 220 and rotating the adjusting screw 221, the adjusting screw 221 will move along its axial direction due to the threaded connection between the adjusting screw 221 and the screw slip 227. The adjusting screw 221 rotates within the screw seat 219 but does not disengage. If it is necessary to reduce the angle between the climbing staircase 224 and the horizontal direction, the adjusting screw 221 is rotated to move it in the direction of the climbing staircase 224. The length of the adjusting screw 221 in the space between the U-shaped support plate 226 and the climbing staircase 224 increases, and the height of the top of the climbing staircase 224 decreases. Thus, by rotating the adjusting screw 221, the angle between the climbing staircase 224 and the horizontal direction can be adjusted, thereby adjusting the height of the working platform 223.

[0074] The manned operation mechanism includes a mother basket and a daughter basket; the daughter basket and the mother basket are in a concentric circle structure, the daughter basket is an inner cylinder and the mother basket is an outer ring.

[0075] Both the mother basket and the daughter basket are cage-type structures. The top surface of the mother basket is formed by an upper ring beam 239, which is fixedly connected to one end of the mother basket column 228. The other end of the mother basket column 228 is fixedly connected to a traveling ring beam 230. An umbrella-shaped ring beam 231 is fixedly installed at the bottom of the traveling ring beam 230. A mesh base plate 240 is laid on the traveling ring beam 230, and a mother basket guardrail 238 is fixedly installed on the mesh base plate 240. A toolbox and a control cabinet 242 are installed on the mesh base plate 240. The secondary PLC control system is placed inside the control cabinet. The top surface of the mother basket column 228... Both ends of the main suspended basket are equipped with support wheels 229. A lighting spotlight 232 is fixedly installed on the bottom surface of the umbrella-shaped ring beam 231. The sub-suspended basket is assembled from a sub-suspended basket column 235 and a sub-suspended basket ring beam 237. The sub-suspended basket ring beam 237 is fixedly installed at both ends of the sub-suspended basket column 235. A sub-suspended basket bottom plate 241 is laid on the sub-suspended basket ring beam installed at the bottom end of the sub-suspended basket column 235. A lower guardrail 236 of the sub-suspended basket is installed on the lower guardrail 236 of the sub-suspended basket. An upper guardrail 233 of the sub-suspended basket is installed on the sub-suspended basket ring beam 237 installed at the top end of the sub-suspended basket column 235. A sub-suspended basket pulley 234 is installed at the top end of the sub-suspended basket column 235.

[0076] The large winch 201 includes a first large winch 201-1 and a second large winch 201-2. The first equipment traction cable 202-1 led out from the first large winch 201-1 passes through the first pulley block 203 and the second pulley block 208 in sequence and is fixedly connected to the cable hole at the top of the guardrail 233 on the sub-basket. The second equipment traction cable 202-2 led out from the second large winch 201-2 passes through the first pulley block 203 and the second pulley block 208 in sequence and is fixedly connected to the cable hole at the top of the ring beam 239 on the mother basket.

[0077] After completing the connection of the equipment traction cable 202 to the mother and daughter suspended baskets and the personnel traction cable to the maintenance personnel, the mother suspended basket is first pulled into the vertical section of the water diversion channel 200 by the second large winch 201-2. When the mother suspended basket reaches the work area, the second large winch 201-2 is stopped to keep the mother suspended basket in the work area. During the lifting process, the support wheel 229 of the mother suspended basket contacts the inner wall of the water diversion channel 200 to provide support for the mother suspended basket. After the mother suspended basket is in the work area, the maintenance personnel put on protective equipment and enter the daughter suspended basket. The daughter suspended basket is lifted to the work area by the first large winch 201-1. During the ascent of the daughter suspended basket, the maintenance personnel simultaneously use the small winch 205 to partially wind up the personnel traction cable 204 to prevent the personnel traction cable 204 from being released too long, which would not be able to protect the maintenance personnel and may also affect the lifting of the daughter suspended basket.

[0078] During the lifting process, the sub-platform can enter the mother platform through the opening in the middle of the umbrella-shaped ring beam 231 and the traveling ring beam 230, so that the bottom of the sub-platform is level with the bottom of the mother platform. During the process of the sub-platform entering the mother platform, the setting of the pulley 234 of the sub-platform can avoid friction or collision with the mother platform, thereby improving the safety of the sub-platform entering the mother platform. After the maintenance personnel enter the mother platform, they can carry out maintenance work.

[0079] Workers can carry the secondary PLC control system with them. However, carrying the secondary PLC control system may interfere with the work. Therefore, during maintenance, the secondary PLC control system can be placed in the control cabinet of the mother hoist.

[0080] The water diversion channel maintenance equipment of the present invention is used in the following manner: (1) The mobile chassis, personnel passage and climbing operation mechanism are assembled in the 200 level section of the water diversion channel.

[0081] (2) Release the steel cable wound on the winch 210 and connect the steel cable to the gantry at the front end of the water diversion channel 200. After the connection is fixed, adjust the rotation direction of the winch 210 to tighten the steel cable, and then stop the winch 210.

[0082] (3) Drill holes at a predetermined position at the top of the horizontal section of the water diversion channel 200 using a regular telescopic ladder and install the first pulley block 203. After the first pulley block 203 is installed, start the large winch 201 and the small winch 205 to release the equipment traction cable 202 and the personnel traction cable 204. Wrap the equipment traction cable 202 and the personnel traction cable 204 around the first pulley block 203 and observe the length of the equipment traction cable 202 and the personnel traction cable 204 so that they can wrap around the second pulley block.

[0083] (4) Start the winch 210 to release the steel cable, and at the same time start the triangular track wheel 212 to cooperate with the speed of the winch 210 in releasing the steel cable, so that the mobile chassis slowly moves towards the vertical section of the water diversion channel 200 and pushes the personnel passage and the climbing operation mechanism to move towards the vertical section of the water diversion channel 200. Observe the position of the mobile chassis, personnel passage and climbing operation mechanism. When the climbing operation mechanism approaches the predetermined installation position of the second pulley group, control the triangular track wheel 212 to slow down the movement speed and make a fine adjustment to the position of the climbing operation mechanism. After completion, control the triangular track wheel 212 to stop moving, and at the same time the personnel passage and the climbing operation mechanism also stop moving. Adjust the rotation direction of the winch 210 again to tighten the steel cable to prevent the equipment from falling.

[0084] (5) Start the swing arm 215 to lower the fixing plate 211 onto the inner wall of the water diversion channel 200. The workers fix the fixing plate 211 to the inner wall of the water diversion channel 200 with expansion bolts. Then, the workers enter the personnel passage and reach the anchor support base 225 through the personnel passage. The bottom end of the anchor support base 225 is anchored to the inner wall of the water diversion channel 200. Then, the workers turn the handwheel 220 to unfold the climbing ladder 224. When the working platform 223 at the top of the climbing ladder 224 rotates to the predetermined installation position of the second pulley group 208, the handwheel 220 stops rotating and the adjusting screw 221 is tightened. The nut is locked to tighten the adjusting screw 221 and the U-shaped support plate 226, thereby locking the climbing staircase 224. Then, the reduction motor 247 is started to extend the telescopic section of the telescopic arm 222. When the rubber pad 243 at the end of the telescopic section of the telescopic arm 222 abuts against the inner wall of the water diversion channel 200, the reduction motor 247 is stopped. Then, a worker climbs to the top of the climbing staircase 224 and anchors the telescopic arm 222 to the inner wall of the water diversion channel 200. After completion, the work platform 223 is leveled and the fixing rod 248 is fixed to the screw hole at the appropriate position on the upper surface of the telescopic arm 222.

[0085] (6) The staff went up to the work platform 223, drilled holes in the inner wall of the water diversion channel 200 and installed the second pulley block 208. After the second pulley block 208 was installed, the large winch 201 and the small winch 205 were started again to release the equipment traction steel cable 202 and the personnel traction steel cable 204. The equipment traction steel cable 202 and the personnel traction steel cable 204 were bypassed around the second pulley block 208. Then the staff returned to the bottom of the climbing work mechanism and returned to the mobile chassis through the personnel passage. The large winch 201 and the small winch 205 were started again to continue to release the equipment traction steel cable 202 and the personnel traction steel cable 204. At this time, the equipment traction steel cable 202 and the personnel traction steel cable 204 extended to the bottom of the vertical section of the water diversion channel 200 by gravity.

[0086] (7) During the process of releasing the equipment traction cable 202 and the personnel traction cable 204 to the bottom of the vertical section of the water diversion channel 200, the personnel at the bottom of the vertical section of the water diversion channel 200 simultaneously assemble the personnel-carrying operation mechanism. When the equipment traction cable 202 and the personnel traction cable 204 reach the bottom of the vertical section of the water diversion channel 200, the large winch 201 and the small winch 205 are stopped. After the personnel securely connect the equipment traction cable 202 to the personnel-carrying operation mechanism, the second large winch 201-2 is started first to wind up the second equipment traction cable 202-2, raising the mother basket to the maintenance operation area. After it is in place, the second large winch is stopped. After the winch 201-2 is activated, the personnel responsible for the maintenance of the inner wall of the water diversion channel 200 enter the sub-hoisted basket and connect the personnel traction cable 204 to themselves. The first large winch 201-1 is started to wind up the first equipment traction cable 202-1, and the sub-hoisted basket is raised to the same level as the mother basket. Then the first large winch 201-1 is stopped. Next, the lower guardrail 236 of the sub-hoisted basket is opened, and the personnel enter the mother basket. The personnel traction cable 204 is wound up until it can hold the maintenance personnel without affecting their movement. Then the small winch 205 is stopped, and the maintenance personnel carry out maintenance work on the inner wall of the water diversion channel 200.

[0087] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.

10. The method of using the water diversion channel maintenance equipment as described in claim 9, characterized in that: The method of use includes the following steps: (1) Assemble the mobile chassis, personnel passage, and climbing operation mechanism in the horizontal section of the water diversion channel (200); (2) Release the steel cable wound on the winch (210) and connect the steel cable to the gantry at the front end of the water diversion channel (200). After the connection is fixed, adjust the rotation direction of the winch (210) to tighten the steel cable and then stop the winch (210). (3) Drill holes at the predetermined position at the top of the horizontal section of the water diversion channel (200) using a regular telescopic ladder and install the first pulley group (203). After the first pulley group (203) is installed, start the large winch (201) and the small winch (205) to release the equipment traction cable (202) and the personnel traction cable (204). Pass the equipment traction cable (202) and the personnel traction cable (204) around the first pulley group (203) and observe the length of the equipment traction cable (202) and the personnel traction cable (204) so ​​that they can pass around the second pulley group. (4) Start the winch (210) to release the steel cable, and at the same time start the triangular track wheel (212) to cooperate with the speed of the winch (210) to release the steel cable, so that the mobile chassis slowly moves towards the vertical section of the water diversion channel (200) and pushes the personnel passage and climbing operation mechanism to move towards the vertical section of the water diversion channel (200). Observe the position of the mobile chassis, personnel passage and climbing operation mechanism. When the climbing operation mechanism approaches the predetermined installation position of the second pulley group, control the triangular track wheel (212) to slow down the movement speed and make a fine adjustment to the position of the climbing operation mechanism. After completion, control the triangular track wheel (212) to stop moving. At the same time, the personnel passage and climbing operation mechanism also stop moving. Adjust the rotation direction of the winch (210) again to tighten the steel cable to prevent the equipment from falling. (5) Start the swing arm (215) to lower the fixing plate (211) onto the inner wall of the water diversion channel (200). The workers fix the fixing plate (211) to the inner wall of the water diversion channel (200) with expansion bolts. Then, the workers enter the personnel passage and reach the anchor support base (225) through the personnel passage. The bottom end of the anchor support base (225) is anchored to the inner wall of the water diversion channel (200). Then, the workers turn the handwheel (220) to unfold the climbing ladder (224). When the working platform (223) at the top of the climbing ladder (224) rotates to the predetermined installation position of the second pulley group (208), the handwheel (220) stops rotating and the screw on the adjusting screw (221) is tightened. The locking screw (221) is locked to the U-shaped support plate (226), thereby locking the climbing staircase (224). Then, the geared motor (247) is started to push out the telescopic section of the telescopic arm (222). When the rubber pad (243) at the end of the telescopic section of the telescopic arm (222) abuts against the inner wall of the water diversion channel (200), the geared motor (247) is stopped. Then, a worker climbs to the top of the climbing staircase (224) and anchors the telescopic arm (222) to the inner wall of the water diversion channel (200). After completion, the work platform (223) is leveled and the fixing rod (248) is fixed to the screw hole at the appropriate position on the upper surface of the telescopic arm (222). (6) The staff went up to the work platform (223), drilled holes in the inner wall of the water diversion channel (200) and installed the second pulley group (208). After the second pulley group (208) was installed, the large winch (201) and the small winch (205) were started again to release the equipment traction cable (202) and the personnel traction cable (204). The equipment traction cable (202) and the personnel traction cable (204) were passed around the second pulley group (208). Then the staff returned to the bottom of the climbing work mechanism and returned to the mobile chassis through the personnel passage. The large winch (201) and the small winch (205) were started again to continue to release the equipment traction cable (202) and the personnel traction cable (204). At this time, the equipment traction cable (202) and the personnel traction cable (204) extended to the bottom of the vertical section of the water diversion channel (200) by gravity. (7) During the process of releasing the equipment traction cable (202) and personnel traction cable (204) to the bottom of the vertical section of the water diversion channel (200), the personnel at the bottom of the vertical section of the water diversion channel (200) simultaneously assemble the personnel-carrying operation mechanism. When the equipment traction cable (202) and personnel traction cable (204) reach the bottom of the vertical section of the water diversion channel (200), the large winch (201) and small winch (205) are stopped. After the personnel securely connect the equipment traction cable (202) to the personnel-carrying operation mechanism, the second large winch (201-2) is started first to wind up the second equipment traction cable (202-2) and lift the mother basket to the maintenance operation area. After it is in place, the second winch is stopped. The large winch (201-2) is then used to carry out maintenance work on the inner wall of the water diversion channel (200). The workers then enter the sub-basket and connect the personnel traction cable (204) to themselves. The first large winch (201-1) is started to wind up the first equipment traction cable (202-1). The sub-basket is then raised to the same level as the mother basket and the first large winch (201-1) is stopped. The lower guardrail (236) of the sub-basket is then opened and the workers enter the mother basket. The personnel traction cable (204) is wound up until it can hold the maintenance workers without affecting their movement. The small winch (205) is then stopped and the maintenance workers carry out maintenance work on the inner wall of the water diversion channel (200).
