Description

Technical Field

[0001] The invention belongs to the technical field of gate cleaning, and in particular relates to an underwater channel cleaning device and a cleaning method. Background Art

[0002] The circulating water of a thermal power plant is an important source of refrigerant water for cooling the exhaust steam of the turbine of the generator set and ancillary equipment. It needs to be supplied continuously. When inspecting and repairing the circulating water pump, the forebay gate must be lowered, and the circulating water pump and the forebay must be effectively isolated. Then, the water in the pool behind the gate must be pumped out before the inspection and repair work can be carried out.

[0003] A Chinese patent with announcement number CN221567038U discloses a hydraulic gate device with a self-cleaning structure. By adding a blocking member and a cleaning mechanism, the blocking member can intercept debris. When the debris accumulates to a certain amount, a rope is used to pass through the second lifting ring to pull the cleaning mechanism upward. The debris will be collected through the cleaning trough and the water will be filtered out through the filter holes, thereby achieving the effect of cleaning the debris.

[0004] As the channel of the gate plate is always underwater, shellfish often breed in the channel, or stones and other debris gather at the bottom of the channel under the action of water flow, resulting in the gate plate being unable to smoothly enter the channel and be placed in the position corresponding to the underwater water inlet foundation gate frame when the gate plate is isolated for maintenance of the circulating water pump. The gate plate is not sealed tightly, and the water in the corresponding circulating water pump inlet side pool cannot be drained, making it impossible to carry out subsequent maintenance work normally.

[0016] A cleaning method for an underwater channel cleaning device, the specific cleaning method is:

[0017] Step 1: When carrying out maintenance work, the gate is in a closed state, and then the water in the pool behind the gate is pumped out before carrying out maintenance work;

[0018] Step 2: While the maintenance work is being carried out, the servo motor is started, and the servo motor drives the screw to rotate. When the screw rotates, it can use the threaded connection between the screw and the threaded sleeve to drive the gate plate to rise until the bottom of the gate plate is flush with the bottom of the top plate. At this time, the electromagnetic plate is started, and the electromagnetic plate will adsorb the gate plate. At this time, the electric valve is closed to prevent the air inside the inflation seat and the sliding sleeve from moving;

[0019] Step 3: Start the water pump. The water pump draws water from the gate front pool through the water inlet joint and transports it to the inside of the water pipe along the water inlet pipe. The water entering the water pipe is sprayed out through the high-pressure nozzle. At the same time, the motor is rotated to work. Under the action of the rotating motor, the water pipe rotates with the high-pressure nozzle. Under the rotation of the high-pressure nozzle, the water is sprayed out to wash the channel.

[0020] Step 4: The filter screen filters the water entering the water inlet joint. When the water pipe rotates, the water pipe drives the driving wheel to rotate through the driving wheel and the driving belt, and the driving wheel drives the filter screen to rotate through the rotating member;

[0021] Step 5: The cleaning block is kept in contact with the surface of the filter screen under the action of the elastic member, and when the filter screen rotates, the cleaning block scrapes off the impurities adhering to the surface of the filter screen;

[0022] Step 6. When the device is cleaned and the gate is raised, water will enter the interior of the device and contact the filter plate. The filter plate will filter the impurities in the water, and when the water continues to flow, the water will drive the impeller to rotate, and when the impeller rotates, it will drive the rotating rod and the generator to run;

[0023] Step 7. When the generator is running, use the electrical connection with the battery to inject electrical energy into the battery, and use the electrical connection between the battery, the rotating motor, the water pump and the servo motor to provide certain assistance for the electrical energy support of the rotating motor, the water pump and the servo motor.

[0024] The beneficial effects of the present invention are as follows:

[0025] 1. The underwater channel cleaning device and method described in the present invention, through the cleaning component set up, when performing cleaning work, the rotating motor drives the high-pressure nozzle to rotate through the water pipe, and the high-pressure nozzle sprays water to flush the channel, which can effectively flush the impurities in the channel to the outside of the channel, thereby preventing the gate from being unable to close due to the influence of impurities when closing, without the need for manual operation, and improving safety.

[0026] 2. The underwater channel cleaning device and cleaning method described in the present invention, through the action of the structures such as the driving wheel and the transmission belt, will drive the filter screen to rotate while the water pipe rotates. The self-rotation of the filter screen can achieve a self-cleaning effect and throw out impurities on the surface. At the same time, when the filter screen rotates, the cleaning block will scrape off the impurities adhering to the filter screen that cannot be thrown away, thereby increasing the cleaning effect of the filter screen and ensuring the filtering efficiency of the filter screen.

[0027] 3. The underwater channel cleaning device and cleaning method described in the present invention, through the carefully set electric valve, when the gate plate is accurately lifted to the specified height, the electromagnetic plate is immediately started, which can quickly and effectively assist in the adsorption and fixation of the gate plate position, and then the electric valve is closed to block the air inside the sliding sleeve and the inflatable seat, effectively preventing the air from flowing between the two, so that the device can achieve stable limiting of the gate plate lifting height with the help of air pressure. This structure not only avoids the up and down movement of the gate plate due to the water flow pressure when the device is cleaned, but also prevents the wear of the screw thread layer due to the movement of the threaded sleeve driven by the gate plate, and performs well in the cleaning effect of the lifting device.

[0028] 4. The underwater channel cleaning device and cleaning method described in the present invention, by setting an impeller, when the device is not sealed and cleaned, water flows through the filter plate and contacts the impeller, the impeller drives the rotating rod to rotate, and the rotating rod drives the generator to operate. During the operation of the generator, since it is electrically connected to the battery, the device can convert kinetic energy into electrical energy and store it in the battery. This structure effectively avoids energy waste and can provide a certain amount of electrical energy for the rotating motor, water pump, electric valve, electromagnetic plate and servo motor, thereby reducing excessive energy consumption during the use of the device.
