Description

Technical Field

[0002] Cooling towers are a common type of equipment found in industrial and commercial buildings. They are used to remove waste heat from cooling water systems and dissipate the heat into the atmosphere through an evaporation process. Cooling towers are a key component of circulating water systems, especially in applications that require a lot of cooling, such as power plants, petrochemical industries, air conditioning systems, etc. During the circulation process, various minerals and other impurities will dissolve in the water. After long-term operation, deposits will form in the spray tank, affecting the cooling effect. In addition, microbial growth can also cause blockage and corrosion problems.

[0003] After searching, the patent with authorization announcement number CN219589479U discloses a cleaning device for a closed cooling tower spray tank, including a cooling tower and a partition cover fixedly connected to the top thereof, a heat exhaust fan fixedly connected inside the partition cover, the partition cover is communicated with the cooling tower, and a filter is fixedly connected to the inner wall of the bottom of the partition cover, a card block is fixedly connected to the inner wall of the cooling tower, a cooling coil is snap-connected inside the card block, a drive box is fixedly connected to the inner wall of the cooling tower, a drive frame is fixedly connected to the surface of one side of the cooling tower, and a drive motor is arranged in the drive frame.

[0004] The above-disclosed cleaning device for the spray trough of a closed cooling tower completes the spraying and cleaning functions through the linkage of multiple mechanical parts such as motors, pulleys, gears and connecting rods, but still has some obvious disadvantages. In actual use, the inner wall of the cooling tower may be uneven, and it is difficult for the scraper to completely fit all parts, especially in the curved or irregular areas of the tower body. The cleaning effect will be greatly reduced, and during the cleaning process, the scraper may accumulate dirt. If it is not cleaned in time, the dirt will contaminate the tower body again, resulting in a decrease in the cleaning effect. Therefore, it is necessary to design a cooling tower spray trough cleaning device in view of the shortcomings of the prior art. Summary of the invention

The positioning protrusion 501 is provided with multiple pieces and is symmetrically fixed to the top of the casing 1. The support seat 502 is connected to the top of the casing 1 through the positioning protrusion 501. The main body of the support seat 502 covers from the center of the top of the casing 1 to the edge of one side of the top. The hinge plate 503 is hinged to the end of the support seat 502. The rotating cylinder 504 is rotatably installed on the support seat 502. The rotating cylinder 504 is a T-shaped cylinder structure. The operating rod 6 is rotatably installed on the top of the rotating cylinder 504. The operating rod 6 is a hollow arc rod.

When the cleaning staff uses the operating lever 6, the rotation of the Mecanum wheel 202 is controlled so that the device can move close to the side of the spray tank, and the rotating cleaning belt 305 can clean the dead corners of the side of the spray tank. During cleaning, the electric push rod 203 is activated at the same time, so that the electric push rod 203 pushes the mounting frame 201 downward, and the electric push rod 203 acts upward on the casing 1, so that the height of the casing 1 can be raised, and the cleaning belt 305 scrubbing on the side of the spray tank can be moved up synchronously, so that the device can perform a wider range of cleaning on the side of the spray tank, and by assembling the counterweight block 9 on the casing 1 in advance, the casing 1 is pressed down by the counterweight block 9 so that the device can be stably fitted in the spray tank, thereby enhancing the stability of the equipment during operation.

After flowing through the telescopic hose 703, the water will flow into the diversion nozzle 702 for spraying. The cleaning staff rotates the operating rod 6 on the rotating cylinder 504. At this time, the cleaning staff can stand on the side of the casing 1 away from the diversion nozzle 702 to push the device. While the cleaning staff controls the device to clean the spray tank through the operating rod 6, the diversion nozzle 702 can follow the movement The device synchronously sprays water into the spray tank for flushing, avoiding the need to additionally pump water into the spray tank for cleaning. In addition, the cleaning staff can also swing the operating lever 6 as needed to make the operating lever 6 drive the rotating cylinder 504 to rotate on the support seat 502. The rotating rotating cylinder 504 will pull the connecting rod II 508 through the connecting rod I 507, so that the connecting rod II 508 drives the mounting block 701 and the guide nozzle 702 to adjust the angle on the hinged plate 503, so that the guide nozzle 702 can spray water at different angles in the spray tank, thereby better adapting to the cleaning work of the scrubbing component 3 and the brushing component 4 on the spray tank. When the scrubbing and brushing operations on the stains in the spray tank are completed, After that, disconnect the water delivery valve on the delivery valve 101 and open the sealing cover 102, and at the same time start the liquid turbine pump 802, the liquid turbine pump 802 generates a low pressure in the operating rod 6 to draw liquid upwards, at this time, the cleaning staff can rotate the operating rod 6 to the side close to the guide nozzle 702, and by pressing the operating rod 6 downward, the operating rod 6 drives the guide nozzle 702 to be pressed into the cleaning waste liquid in the spray tank through the rotating cylinder 504 and the connecting rod I 507 and the connecting rod II 508 in turn. Under the action of the low pressure in the operating rod 6, the guide nozzle 702 can draw the cleaning waste liquid into the telescopic hose 703, and the cleaning waste liquid is gradually drawn upwards into the operating rod 6 after flowing through the telescopic hose 703. When the cleaning waste liquid When the liquid is drawn upward in the operating rod 6, the cleaning waste liquid will be filtered at the screen 803, and the waste liquid impurities or stains filtered by the screen 803 will fall into the separation tube 801, and the waste liquid passing through the screen 803 will be discharged from the port of the operating rod 6, thereby separating the solid and liquid in the cleaning waste liquid so that the cleaning staff can collect and process them separately. When the spray tank is cleaned, the block 506 can be aligned on the slot of the support seat 502 by twisting the block 506, and the support seat 502 can be disengaged from the positioning protrusion 501 by lifting the operating rod 6 upward, so that the entire mounting assembly 5 and the operating rod 6 can be removed from the casing 1, so that the mounting assembly 5 and the operating rod 6 can be cleaned and maintained.
