[0002] The rock anchor beam side wall hanging plate of the main powerhouse of a hydropower station is a structure used to fix the rock anchor beam. The rock anchor beam is an important structure used to support and fix the main powerhouse of a hydropower station. Its function is to withstand various loads such as water pressure, earthquake and wind load to ensure the stability and safety of the main powerhouse. The rock anchor beam side wall hanging plate is usually made of steel, which has high strength and rigidity and can withstand a large amount of water pressure and seismic force. The hanging plate needs to be fixed to the rock anchor beam by bolts or welding to ensure that it is firm and immovable. In the construction of a hydropower station, the design and manufacture of the rock anchor beam side wall hanging plate needs to consider many factors, such as rock mass characteristics, water pressure, seismic force, temperature changes and corrosion. In order to ensure the stability and safety of the main powerhouse, high-quality materials and advanced manufacturing processes are required to ensure that the hanging plate can withstand all loads and environmental influences.

At the same time, the roller brush 204 is adsorbed with the factory building body 101 through the suction cup 205, so that the roller brush 204 can be close to the wall of the factory building body 101. At the same time, the suction cup 205 is circular and will rotate with the lifting of the shell 107. At the same time, a negative pressure pump is also provided inside the suction cup 205, through which the suction cup 205 generates suction to fix it, and a mounting part 207 used in conjunction with the wiping piece 206.

[0038] Specifically, the traction member 106 includes a servo motor 106a and a winding wheel 106b arranged on the mounting frame 105. The winding wheel 106b and the turntable 201 are installed on the same rotating shaft, and one end of the rotating shaft is fixedly installed on the output end of the servo motor 106a, and a rope 106c is wound on the winding wheel 106b.

[0042] Example 2

[0043] Reference Figure 4 - Figure 6, which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that the wiping member 206 includes rotating plates 206a symmetrically arranged at both ends of the roller brush 204, and the rotating plates 206a on both sides are provided with independent power sources, thereby driving the rotating plates 206a to rotate and rotate the rectangular blocks 206b installed on the rotating plates 206a, the rectangular blocks 206b are arranged at both ends of the rotating plates 206a, and both ends of the rectangular blocks 206b are provided with torsion springs, and sponge pads 206c are arranged on the rectangular blocks 206b, and the hanging plates of the factory body 101 are wiped by the sponge pads 206c.

[0044] Specifically, the sponge pad 206c is composed of two parts. The side of the sponge pad 206c close to the rectangular block 206b is a hard mounting plate. The mounting part 207 includes a circular groove 207a symmetrically opened on the sponge pad 206c, a cylinder 207b symmetrically arranged on the rectangular block 206b, the cylinder 207b and the circular groove 207a can be engaged with each other, a placement groove opened on the cylinder 207b, and an arc block 207c and a second spring 207d arranged in the placement groove.

[0045] Furthermore, the number and size of the circular grooves 207a are consistent with those of the cylinder 207b, and the second spring 207d is located between the arc block 207c and the placement groove.

[0046] The rest of the structure is the same as that of Example 1.

[0047] Operation process: when the double-drive end servo drives the roller brush 204 to rotate, the power source of the rotating plate 206a will also drive it to rotate, so that the bottom of the rotating plate 206a is close to the hanging plate of the plant body 101. At this time, the matching sponge pad 206c will contact and be squeezed with the plant body 101, and gradually fit with the surface of the plant body 101. The reaction force of the torsion spring makes the sponge pad 206c fit more closely. As the shell 107 descends, the cleaning liquid dripping from the surface of the plant body 101 and the roller brush 204 is wiped. After reaching the bottom of the hanging plate of the plant body 101, the roller brush 204 and the rotating plate 206a rotate in the opposite direction, and the shell 107 is driven to rise through the traction member 106. At the same time, the top of the rotating plate 206a will move toward the plant body 1 01's hanging plate is close to it, and the matching sponge pad 206c will repeat the above steps to wipe the factory body 101. The hanging plate of the factory body 101 can also be wiped with the sponge pad 206c alone. After cleaning, the sponge pad 206c can be removed from the rectangular block 206b by pulling it outward. When installing a new sponge pad 206c, the cylinder 207b is inserted into the circular groove 207a on the sponge pad 206c. The arc block 207c is squeezed and moved toward the depth of the placement groove. After the cylinder 207b is engaged with the circular groove 207a, the arc block 207c is reset by the reaction force of the second spring 207d, and the inner wall of the circular groove 207a is expanded, so that the sponge pad 206c can be fixed on the rectangular block 206b.

[0048] Example 3

[0049] Reference Figure 7 - Fig. 9 , which is the third embodiment of the utility model. Different from the above embodiments, this embodiment provides an anti-fall cleaning device, including the above-mentioned cleaning mechanism, and also includes a braking assembly 300, including a gear ring 301 arranged on the mounting frame 105, the inner ring of the gear ring 301 is provided with a plurality of teeth, a sliding connecting rod 302 slidably installed in the rotating shaft, the sliding connecting rod 302 can move by centrifugal force, a round block 303 and a limit block 304 fixedly installed on the sliding connecting rod 302, the round block 303 is installed on a side close to the limit block 304, the weight of the limit block 304 is increased by the round block 303, so that when the sliding connecting rod 302 moves by centrifugal force, it will move toward the end where the limit block 304 is installed, and a deceleration member 305 used in conjunction with the limit block 304, and the deceleration member 305 is used to further improve the braking effect.

[0050] Specifically, the speed reducer 305 includes an L-shaped frame 305a fixedly installed on the sliding link 302, a fixed frame 305b and a guide rail 305c fixedly installed on the surface of the rotating shaft, a cross bar 305d fixedly installed between the fixed frame 305b and the rotating shaft, and a slider 305e slidably installed on the cross bar 305d. The slider 305e can move on the surface of the cross bar 305d and rotate a connecting block 305f installed between the slider 305e and the L-shaped frame 305a. The L-shaped frame 305a pushes the connecting block 305f when moving, and pushes the slider 305e and the metal block 305g slidably installed in the guide rail 305c through the connecting block 305f. The metal block 305g is fixedly installed on the slider 305e, and a magnet 306 arranged on the mounting frame 105. Carbon fibers are arranged on both sides of the magnet 306 to prevent the magnetic field of the magnet 306 from affecting the rotating shaft.

[0051] Furthermore, a third spring is provided on the surface of the crossbar 305d and between the rotating shaft and the slider 305e. The slider 305e is reset by the reaction force of the third spring. The magnet 306 is in the shape of a circular ring.

[0052] The rest of the structure is the same as that of Example 2.

[0053] Operation process: When the traction member 106 fails, causing the housing 107 to fail, the rotation speed of the shaft will increase, and the sliding link 302 will slide in the shaft through the centrifugal force. At the same time, the weight of the limit block 304 is increased by the round block 303, so that the sliding link 302 will move toward the end where the limit block 304 is installed when it moves due to the centrifugal force, so that the limit block 304 will be inserted into the teeth of the inner ring of the gear ring 301, thereby braking. At the same time, when the sliding link 302 moves, it will also drive the L-shaped frame 305a to move, and at the same time, the L-shaped frame 305a When moving, the connecting block 305f is pushed, and the slider 305e is pushed to move in the direction of the rotating shaft through the connecting block 305f. While moving, the metal block 305g is pushed to contact the magnet 306 and rub with the rotation of the rotating shaft, and the rotating shaft is slowed down by the friction force and the magnetic force, thereby further improving the braking effect. After the braking is completed, the sliding link 302 is reset and the L-shaped frame 305a is reset at the same time. The reaction force of the third spring allows the slider 305e to be reset, and at the same time, the slider 305e pulls the metal block 305g to separate from the magnet 306 and reset it.
