[0005] In response to the above problems, the existing patent uses side brushes and bottom brushes to clean the inner wall and bottom of the cooling tower at the same time. However, when the brushes are scrubbing the inside of the cooling tower, when the brushes encounter raised scale and dirt, it is inconvenient to adjust the scale and dirt by adjusting the scrubbing force, thereby affecting the cleaning effect of the scale and dirt inside the cooling tower.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The utility model provides a technical solution:

[0029] See also Figure 1 , Figure 4 and Figure 5A cooling tower cleaning device comprises a carrier frame 1, a driving motor 2 is fixedly installed at the middle position of the carrier frame 1, a driving rod 3 is fixedly connected to the output end of the driving motor 2, a liquid injection component 4 is installed at the fixed connection between the driving rod 3 and the driving motor 2, the output end of the liquid injection component 4 is connected to a connecting hose 11, the output end of the connecting hose 11 is connected to a cleaning nozzle 6, the output end of the connecting hose 11 is also connected to a force adjustment component 7, the internal movably connected to the driving rod 3 are multiple groups of equally spaced bearing rods 5, and the top of the bearing rod 5 is connected to a cleaning brush 10 through the force adjustment component 7;

[0030] The force adjustment component 7 includes a water injection cylinder 701 fixed inside the end of the supporting rod 5 away from the driving rod 3, the inside of the water injection cylinder 701 is slidably connected with a push rod 702, the end of the push rod 702 away from the water injection cylinder 701 is rotatably connected to a connecting seat 8, a torque sensor 9 is installed on the end surface of the connecting seat 8, the torque sensor 9 is fixedly connected to the rotating shaft of the connecting seat 8, the end of the water injection cylinder 701 is connected to the connecting hose 11 through a water injection valve pipe 706, the outer side of the water injection cylinder 701 is provided with a first spring 704, the side wall of the water injection cylinder 701 is connected with a drain valve pipe 703, and a sealing ring 705 is embedded at the connection between the water injection cylinder 701 and the push rod 702.

[0031] By adopting the above technical solution, when in use, the supporting frame 1 is set up on the top of the cooling tower, the injection component 4 is connected to the external water supply device, and the injection component 4 is connected to the cleaning nozzle 6 through the connecting hose 11, so that the cleaning nozzle 6 can spray high-pressure water to clean the inside of the cooling tower, and the driving motor 2 is started. The driving motor 2 can drive the driving rod 3 and the supporting rod 5 to rotate, so that the cleaning nozzle 6 and the cleaning brush 10 can rotate to perform high-pressure spraying and brushing on the inside of the cleaning tower. When the cleaning brush 10 is rotating and brushing, it will encounter raised scale and dirt, and the scale and dirt will have a certain blocking effect on the cleaning brush 10, so that the cleaning brush 10 rotates at the top of the push rod 702 through the connecting seat 8, thereby triggering The torque sensor 9 is used for monitoring. When it is detected that the cleaning brush 10 encounters relatively solid dirt, the water injection valve tube 706 is connected to the connecting hose 11 to inject water into the water injection cylinder 701. The water pressure inside the water injection cylinder 701 increases, which can push the push rod 702 to move, so that the push rod 702 can push the cleaning brush 10 to squeeze the dirt, and use stronger pressure to brush the dirt, thereby ensuring the cleaning effect of raised solid scale dirt.

The cleaning water in the water injection cylinder 701 is discharged, reducing the water pressure in the water injection cylinder 701, thereby restoring the initial brush force cleaning, thereby achieving the effect of adjusting the brushing force.

[0032] Specifically, Figures 1 to 3As shown, the injection assembly 4 includes a connecting sleeve 401 rotatably sleeved at the connection between the driving motor 2 and the driving rod 3, the two ends of the inner part of the connecting sleeve 401 are connected to the top of the driving rod 3 through bearings, the top of the driving rod 3 is a cylindrical structure, the connecting hose 11 is embedded in the driving rod 3, and a water injection pipe 402 is fixedly installed on the outer wall of the connecting sleeve 401. A connecting hole 403 is provided inside the connecting sleeve 401. The connecting hole 403 is opened on the driving rod 3 and communicates with the connecting hose 11. The water injection pipe 402 is connected to the connecting hose 11 through the connecting sleeve 401 and the connecting hole 403. A plurality of equally spaced expansion slots 12 are provided on the side wall of the rod 3, and a second spring 13 is installed inside the expansion slot 12. One end of the second spring 13 is fixed on the inner wall of the expansion slot 12, and the other end of the second spring 13 is connected to the end of the load-bearing rod 5. The end of the load-bearing rod 5 is slidably connected to the expansion slot 12, and a limiting ring is fixed at the connection between the end of the load-bearing rod 5 and the expansion slot 12. The length of the connecting hose 11 inside the expansion slot 12 is greater than the moving length of the load-bearing rod 5 in the expansion slot 12. The movement of the load-bearing rod 5 in the expansion slot 12 can drive the connecting hose 11 to extend in the expansion slot 12.

[0033] By adopting the above technical solution, the water injection pipe 402 is connected to the external water supply device to introduce clean water into the connecting sleeve 401, and the water inside the connecting sleeve 401 is injected into the connecting hose 11 through the connecting hole 403. The connecting hose 11 can inject water into the cleaning nozzle 6 and the water injection cylinder 701. When the driving motor 2 drives the driving rod 3 and the bearing rod 5 to rotate, the centrifugal force will drive the bearing rod 5 to move in the telescopic groove 12, so that the cleaning brush 10 at the top of the bearing rod 5 can fit with the inner wall of the cooling tower, and the distance between the bearing rod 5 and the cooling tower can be adjusted, so that the bristles of the cleaning brush 10 can fully brush the inner wall of the cooling tower. At the same time, the elastic expansion and contraction of the bearing rod 5 can play a buffering effect. At the same time, the setting of the second spring 13 and the limit ring can play a limiting effect, thereby preventing the bearing rod 5 from detaching from the telescopic groove 12 under the action of centrifugal force.

[0034] Working principle: When in use, the supporting frame 1 is set up on the top of the cooling tower, and the injection component 4 is connected to the external water supply device. The injection component 4 is connected to the cleaning nozzle 6 through the connecting hose 11, so that the cleaning nozzle 6 can spray high-pressure water to clean the inside of the cooling tower. The driving motor 2 is started. The driving motor 2 can drive the driving rod 3 and the supporting rod 5 to rotate. The cleaning brush 10 is connected to the supporting rod 5 through the force adjustment component 7 and the connecting seat 8, so that the cleaning nozzle 6 and the cleaning brush 10 can be rotated to perform high-pressure spraying and brushing on the inside of the cleaning tower. The driving motor 2 can drive the driving rod 3 and the supporting rod 5 to rotate, and the centrifugal force will drive the supporting rod 5 to move in the telescopic groove 12, so that the cleaning brush 10 at the top of the supporting rod 5 can fit with the inner wall of the cooling tower, so that the bristles of the cleaning brush 10 can fully brush the inner wall of the cooling tower.
