Manual cleaning during shutdown mainly adopts mechanical brush cleaning and high-pressure water injection cleaning; online cleaning is mainly divided into chemical cleaning (mainly acid cleaning) and cleaning by placing rubber balls in the condenser. After searching, the prior art (application number: CN202120325467.9) records "a power plant condenser online cleaning manipulator device, including a frame and a power source drive assembly installed on the frame, a travel switch, at least one set of cleaning head assemblies, a set of water and gas passage assemblies and at least one movable base beam; the power source drive assembly drives the movable base beam to reciprocate in the longitudinal direction; the travel switch is used to limit the travel range of the movable base beam in the longitudinal direction; the cleaning head assembly is installed on the movable base beam and reciprocates synchronously with the movable base beam, the cleaning head assembly includes a rectangular tube, a plurality of nozzles installed on the rectangular tube, a silicone nozzle sleeved on the nozzle, and a guide bearing component fixed on the rectangular tube; the water and gas passage assembly is used to transport cleaning liquid and provide a power gas source. The device has the advantages of high degree of automation, wide cleaning coverage and simple mechanical structure."

[0003] However, although the online cleaning robot device for power plant condensers in the prior art has achieved automated cleaning, it still has some shortcomings: the existing power plant condenser cleaning robot device is still relatively troublesome for cleaning the pipes inside the condenser. Whether it is done manually or online, the cleaning efficiency is low, and it can only be achieved by high-pressure flushing of the cleaning liquid and the outer wall or the inner wall of the condenser pipe. Not only does it waste a lot of cleaning liquid, but the stubborn scale inside the pipe is not easy to rinse clean, resulting in poor cleaning effect and low efficiency. Utility Model Content

[0004] In order to overcome the defects of the prior art, a power plant condenser cleaning robot is provided to solve the problems of low cleaning efficiency and poor cleaning effect of the existing power plant condenser cleaning robot device.

[0005] To achieve the above-mentioned purpose, a power plant condenser cleaning robot is provided, comprising: a robot arm, a cleaning assembly and a lifting assembly, the robot arm is installed on the ground, the lifting assembly is installed on the lower side of the robot arm, and the cleaning assembly is connected to the lower side of the lifting assembly, the cleaning assembly comprises a movable frame, and a water tank and a high-pressure pump are provided on the upper side of the movable frame, and a movable disk with a sliding connection is provided on the inner side of the movable frame, a vibrator is installed on one side of the movable disk, and a cleaning rod is connected to the other side, the cleaning rod comprises a hollow rod, and one end of the hollow rod is screwed to the movable disk, and steel wire bristles are welded on the surface of the hollow rod, and a water spray hole is opened.

[0007] Furthermore, the lifting assembly also includes a connecting plate connected to the lower end of the electric slider, and the lower end of the connecting plate is connected to an electric push rod, and the base of the electric push rod is fixed on the upper side of the movable frame.

[0008] Furthermore, the water tank is provided with cleaning liquid, and the water tank is connected to the high-pressure pump through a pipeline, and the water outlet of the high-pressure pump is connected to the movable disk through a hose.

[0009] Furthermore, the movable disk is configured as a disk structure, a hollow cavity is provided inside the disk, and a screw hole is provided on an end surface of the disk facing away from the vibrator.

[0010] Furthermore, the upper and lower ends of the movable disk are respectively connected with an upper guide block and a lower guide block, and an upper guide rod is slidably connected in the upper guide block, and a lower guide rod is slidably connected in the lower guide block, and the upper guide rod and the lower guide rod are parallel to the cleaning rod.

[0013] The beneficial effects of the utility model are:

[0014] 1. When in use, keep the condenser fixed in the axial direction of the cleaning rod, then adjust the angle of the cleaning component through the mechanical arm, and adjust the height of the cleaning component through the lifting component, and then drive the movable frame through the electric slider to insert the tip end of the cleaning rod into the pipe opening of the condenser. At this time, start the high-pressure pump, vibrator and motor, and use the high-pressure pump to pump the cleaning liquid in the water tank into the hollow rod and then spray it out from the water spray hole, so that it contacts the dirt on the inner wall of the pipe. The hollow rod is driven to vibrate by the vibrator, so that the steel wire bristles on the outside are constantly in friction contact with the inner wall of the pipe, and then the motor drives the screw rod to drive the movable disk to reciprocate linearly, so that the cleaning rod performs reciprocating linear cleaning operations in the condenser pipe, which enhances the cleaning effect and improves the cleaning efficiency;

[0015] 2. When cleaning the outside of the condenser, first keep the condenser and the cleaning rod on the same horizontal line and install them on a rotatable bracket. At the same time, keep the cleaning rod parallel to the outside of the cylinder of the condenser, and keep the wire bristles on the cleaning rod in contact with the condenser. At this time, the cleaning rod cannot contact the entire condenser surface, so the cleaning rod that is not in contact with it is removed and the screw hole is blocked with a plug. At this time, turn on the high-pressure pump, vibrator and motor to vibrate, flush and brush the outside of the condenser, and keep the condenser rotating to achieve a complete cleaning effect.
