Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] As shown in Figure 1, the two-joint online cleaning robot for condenser copper tubes of the present invention includes a nozzle 3, a small arm 4, a rotating water chamber 6, a rotary encoder 8, a small arm hydraulic driver 9, a large arm 11, and a rotating handle. Arm 14, water inlet chamber 17, large arm hydraulic driver 19, bracket 20 and control mechanism, wherein the rotating crank arm 14 is arranged in the condenser water chamber 28, and is connected to the outer wall of the condenser water chamber 28 through the water outdoor support assembly 16 , and is connected to the inner wall of the condenser water chamber 28 through the support assembly 13 in the water chamber. Using this kind of bearing hard support can not only make the rotating crank arm 14 rotate freely, but also ensure firmness and reliability, and can avoid the impact caused by high w...

Abstract

The two joint type robot for on-line cleaning of condenser copper tube includes a nozzle, a small arm, a rotary water chamber, a rotary coder, a hydraulic small arm driver, a large arm, a rotary connecting lever, a water inlet chamber, hydraulic large arm driver and a control mechanism. The rotary connecting lever set inside the condenser water chamber is connected to the hydraulic large arm driver outside the condenser water chamber with the water inlet chamber connected to the control mechanism in between; the large are is connected and communicated to the rotary connecting lever; the rotary water chamber in the top of the large arm is connected to the hydraulic small arm driver with the rotary coder in between; and the small arm is set on and communicated to the rotary water chamber and has the nozzle set on it. The present invention can operate in water to clean copper tubes of condenser with high pressure water as cleaning medium.

Description

technical field [0001] The invention mainly relates to the field of condenser cleaning equipment, in particular to a condenser copper tube two-joint online cleaning robot. Background technique [0002] In the prior art, when the steam turbine condenser is running, due to unclean cooling water quality and chemical reactions during heat exchange, dirt accumulates on the inner wall of the heat exchange tube. The existence of these dirt reduces the heat transfer capacity of the heat exchange surface , so that the exhaust temperature of the steam turbine increases, the output power decreases, and the heat rate increases, so it must be cleaned. At present, the commonly used methods are: manually flushing copper pipes; cleaning copper pipes with chemical agents; manually cleaning copper pipes with high-pressure water guns; cleaning copper pipes with rubber balls, etc. Manual cleaning, due to the large number of condenser heat exchange tubes, long length, high labor intensity, and ...
