Abstract
Description
Technical Field
[0001] This utility model relates to the field of cooling tower spraying technology, specifically a local spraying device for cooling towers. Background Technology
[0002] A cooling tower is a cooling device used to cool hot water or steam through evaporation. When hot water or steam passes through a cooling tower, the water and air exchange heat, the water evaporates and carries away a large amount of heat, thus lowering the water temperature. The cooling water in the cooling tower is eventually recycled and reused, thereby achieving the purpose of cooling the equipment.
[0003] The cooling tower sprays hot water into the tower body through a spray device. However, the spray parts in traditional cooling towers are all fixedly installed. Their fixed positions can easily lead to uneven heating and cooling on the tower surface, reducing the service life of the tower. In addition, due to the minerals in the water, scale can easily accumulate near the nozzle outlet, causing blockages. Manual cleaning is required, which is inconvenient, time-consuming and labor-intensive. Utility Model Content
[0004] In view of the problems existing in the prior art, this utility model discloses a local spraying device for cooling towers. The technical solution adopted includes a mounting frame, a rocking structure, a U-shaped frame, a rotating part, a connecting interface, lower nozzles, a lower mounting frame, a left mounting groove, a right through groove, a lower lead screw, a lower motor, a lower mounting block, a cleaning shaft, a rotating structure, and a cleaning brush. The mounting frame is equipped with a rocking structure, and a rotating part is provided on the inner side. The U-shaped frame is installed through the rotating part. The rocking structure allows each U-shaped frame to rock back and forth. The horizontal part of the U-shaped frame has a cavity that communicates with the connecting interface at the upper part. The water inlet pipe is fixedly connected to the connecting interface. Several lower nozzles are distributed below the horizontal part of the U-shaped frame. The direction of the nozzles can be adjusted... The system adapts to the swaying of the U-shaped frame, resulting in more even spraying. The lower mounting frame is integrally formed on both the left and right sides. The left side of the lower mounting frame has a left mounting groove on its right side wall, and the right side of the lower mounting frame has a right through groove. A lower lead screw is rotatably installed in the right through groove, driven by a lower motor. The lower mounting block is fitted into the right through groove and is installed in conjunction with the lower lead screw. A cleaning shaft is rotatably installed on the left side of the lower mounting block. The left end of the cleaning shaft engages with the rotating structure in the left mounting groove for transmission. Cleaning brushes, which are stiff-bristled brushes, are distributed on the cleaning shaft. Under the operation of the lower motor, the lower mounting block moves along the right through groove with the cleaning shaft. During the movement, the rotating structure causes the cleaning shaft to rotate, driving the cleaning brushes to clean the outlet of the lower nozzle.
[0005] As a preferred technical solution of this utility model, the rocking structure includes an upper mounting groove, an upper rotating screw, an upper motor, a mounting rod, an upper rod body, and a rocking plate. The upper mounting groove is opened on the left side of the upper surface of the mounting frame. The upper rotating screw is rotatably installed in the upper mounting groove and is driven by the upper motor. The lower end of the mounting rod is placed in the upper mounting groove and is installed in conjunction with the upper rotating screw. The upper end of the mounting rod is integrally formed into the upper rod body. Several rocking plates are evenly distributed on the right side wall of the upper rod body. When the upper motor is started, it drives the upper rotating screw to rotate. Initially, the U-shaped frame is in a vertical state. The rotation of the rotating screw drives the rocking plates to move quickly, which can impact the vertical part of the U-shaped frame, causing it to rock back and forth under the impact and inertia conditions.
[0006] As a preferred technical solution of this utility model, the rotating part includes a fixed ring and a rotating shaft. Several fixed rings are evenly fixed on the two inner walls of the mounting frame, and the rotating shaft is fixed on the outer wall of the vertical part of the U-shaped frame. The outer end of the rotating shaft is movably inserted into the fixed ring.
[0007] As a preferred technical solution of this utility model, heat insulation sleeves are provided on both the upper motor and the lower motor.
[0008] As a preferred technical solution of this utility model, the rotating structure includes a gear and a rack. The gear is fixed to the left end of the cleaning shaft, and the rack is fixed to the bottom surface of the mounting groove on the left side. The gear and the rack mesh with each other. When the gear moves with the cleaning shaft, it rotates under the meshing action with the rack, thereby driving the cleaning shaft to rotate.
[0009] The beneficial effects of this utility model are as follows: the shaking structure allows the U-shaped frame to sway, which in turn causes the lower nozzle below to sway, making the spraying of the lower nozzle more uniform and ensuring that the surface of the cooling tower is heated evenly, thus avoiding any impact on its service life. The lower mounting block, lower lead screw, cleaning shaft, rotating structure, and cleaning brush are used to regularly clean the outlet of the lower nozzle, preventing scale buildup and blockage.

The left end of the cleaning shaft 19 is connected to the rotating structure in the left mounting groove 14 for transmission. The cleaning shaft 19 is equipped with cleaning brushes 22, which are hard bristle brushes.
[0016] As a preferred technical solution of this utility model, the rocking structure includes an upper mounting groove 2, an upper rotating screw 3, an upper motor 4, a mounting rod 5, an upper rod body 6, and rocking plates 7. The upper mounting groove 2 is opened on the left side of the upper surface of the mounting frame 1. The upper rotating screw 3 is rotatably installed in the upper mounting groove 2. The upper rotating screw 3 is driven by the upper motor 4. The lower end of the mounting rod 5 is placed in the upper mounting groove 2 and is installed in conjunction with the upper rotating screw 3. The upper end of the mounting rod 5 is integrally formed into the upper rod body 6. Several rocking plates 7 are evenly distributed on the right side wall of the upper rod body 6.
[0017] As a preferred technical solution of this utility model, the rotating part includes a fixing ring 9 and a rotating shaft 10. Several fixing rings 9 are evenly fixed on the two inner walls of the mounting frame 1. The outer walls of the vertical part of the U-shaped frame 8 are all fixed with rotating shafts 10, and the outer end of the rotating shaft 10 is movably inserted into the fixing ring 9.
[0018] As a preferred technical solution of this utility model, heat insulation sleeves are provided on both the upper motor 4 and the lower motor 17.

[0020] The working principle of this utility model is as follows: Initially, the U-shaped frame is vertical. The rotating screw drives the swaying plate to move rapidly, impacting the vertical part of the U-shaped frame and causing it to sway back and forth under the impact and inertia. This swaying causes the lower nozzles below to also sway, making the spray from the lower nozzles more uniform and ensuring that the surface of the cooling tower is heated evenly, thus avoiding any impact on its service life. Periodically starting the lower motor drives the lower screw to rotate, and the lower mounting block moves back and forth, causing the cleaning shaft to move back and forth. During the movement, the meshing between the gear and the fixed rack causes the gear to rotate, thereby rotating the cleaning shaft. The cleaning brush on it periodically cleans the outlet of the lower nozzle to prevent scale buildup and blockage.
