Problems solved by technology
In the complex environment of the water chamber, the high-pressure hose is prone to disturbance, and there will be winding problems when the cleaning mechanism is in motion; moreover, if the high-pressure hose is used, it is also necessary to be equipped with a coil device to control the shrinkage of the high-pressure hose, which greatly increases the the complexity of the washing machine
[0006] 2. Most of the existing cleaning nozzles use a single nozzle, and the cleaning efficiency is low
[0007] 3. Most of the screw transmission mechanisms used by the existing cleaning mechanism have a large radial load on the screw; long-term operation will cause a large radial deformation of the screw
This cannot guarantee the positioning accuracy of the drive screw

Embodiment Construction
[0037] The following is attached Figure 1 to Figure 5 , and Examples, the present invention is further described.
[0038] Such as Figure 4 As shown, the present invention is based on an embedded online cleaning robot for condenser pipes of power plants, which is installed in the right water chamber. The condenser shell is integrated with the cylinder of the upper low-pressure steam turbine. The steam flowing in from the upper low-pressure steam turbine comes from high-purity non-salt water. In order to avoid waste, it needs to be cooled into condensed water through the condenser, and then sent to the boiler for further use. In the condenser, dense condensation tubes are arranged from one end to the other, the water inlet chamber communicates with the right end of the tube bundle, and the water outlet chamber communicates with the left end. Cooling water flows in from the water chamber of the water inlet at the right end, enters the tube bundle of the condenser tube, and ...

The invention belongs to the technical field of industrial cleaning, in particular to an embedded power plant condenser condensation pipe online cleaning robot. The robot comprises a frame; the frameis arranged in a water chamber of a condenser; guide mechanisms are symmetrically and horizontally arranged in the frame up and down, and are horizontally provided with lead screw transmission mechanisms at the middle parts; a driving mechanism connected with input ends of the lead screw transmission mechanisms is arranged on the outer side of the frame; middle sections of nozzle pipes are vertically and movably mounted on the lead screw transmission mechanisms in the frame, and upper and lower sections are movably arranged on the guide mechanisms; multiple nozzles are arranged on the nozzle pipes; the nozzles are aligned to pipe orifices of condensation pipes one to one; water inlet ends are arranged on the nozzle pipes, and movably communicate with rotating mechanical arms through lowerrotating joints; and the rotating mechanical arms are movably connected with water inlet pipes penetrating through the top of the frame, through upper rotating joints. The robot is simple in structure, stable in operation and high in cleaning efficiency, and realizes real-time online cleaning of the inner walls of the condensation pipes in the condensation water chamber of a power plant.
Description
technical field [0001] The invention belongs to the technical field of industrial cleaning, and in particular is based on an embedded online cleaning robot for condenser pipes of power plant condensers. Background technique [0002] Condenser is one of the key equipment in electric power, chemical industry, food, pharmaceutical and other industries. It plays the role of cooling and buffering in the steam turbine, which can reduce the exhaust pressure and temperature of the steam turbine and improve the cycle thermal efficiency of the generator set. A large condenser consists of tens of thousands of condenser tubes. If the cooling water flowing through the condenser tubes is not clean, chemical reactions often occur during heat exchange, causing the condenser to accumulate dirt and even blockage. Dirt deteriorates the heat transfer performance of the condenser, causing a sharp drop in the vacuum degree of the steam turbine, a sharp drop in power generation efficiency, and an ...
