Abstract
Description
Technical Field
[0001] This utility model relates to the field of cooling towers, specifically a cooling tower descaling device. Background Technology
[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and release it into the atmosphere to lower the water temperature. Its cooling mechanism utilizes the heat exchange between water and air to generate steam. The steam evaporates, carrying away heat through evaporative heat transfer, convective heat transfer, and radiative heat transfer. This process dissipates waste heat generated in industrial processes or refrigeration and air conditioning systems, thus lowering the water temperature and ensuring the normal operation of the system. The device is typically cylindrical, hence the name cooling tower. A cooling tower is a comprehensive product integrating aerodynamics, thermodynamics, fluid mechanics, chemistry, biochemistry, materials science, static and dynamic structural mechanics, and manufacturing technology. Water quality is a function of multiple variables, and cooling is an even more complex process involving multiple factors, variables, and effects.
[0003] Existing cooling towers are typically open-type and exposed to the outdoor environment for extended periods. The fans inside these towers have strong suction, causing a large amount of airborne sediment and dirt to enter and form scale. Simultaneously, the cooling towers use water circulation, and the calcium and magnesium ions from the evaporating water deposit on the inner walls of the tower, forming scale. Excessive scale and dirt buildup can clog the water distributor's outlet holes, reducing the cooling tower's heat dissipation capacity. Furthermore, this scale and sediment can enter the cooling system with the cooling water, directly affecting its normal cooling performance and potentially damaging the cooling equipment. Therefore, a cooling tower descaling device is proposed to address these problems. Utility Model Content
[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a cooling tower descaling device, including a cooling tower body. A climbing component for moving up and down along the inner wall of the cooling tower body is provided inside the cooling tower body. A telescopic component is provided on the climbing component. An electric slide rail for driving the telescopic component to rotate horizontally is provided on the climbing component. A brush is provided at each of the two telescopic ends of the telescopic component.
[0005] Furthermore, the climbing component includes a ring. A ring is provided inside the cooling tower body. Four electric push rods (first type) are fixedly installed on the outer side of the ring, arranged in a ring at equal intervals around the center of the ring. Two electric push rods (second type) are fixedly installed on the top of the ring. The moving ends of the two electric push rods (second type) are fixedly connected to a circular plate. Four electric push rods (third type) are fixedly installed on the outer side of the circular plate, arranged in a ring at equal intervals around the center of the circular plate. Support blocks are fixedly installed on the telescopic ends of the electric push rods (first type) and the electric push rods (third type). A rubber anti-slip pad is provided on one side surface of the support block.
[0006] Furthermore, the telescopic component includes a bracket, the moving end of the electric slide rail is provided with a bracket, a servo motor is fixedly installed on the inner side of the bracket, a rotating shaft is fixedly installed on the output end of the servo motor, a bevel gear is fixedly installed on one end of the rotating shaft, an electric slide rail is fixedly installed on the top of the ring, two connecting seats are fixedly installed on the electric slide rail, a rotating shaft is rotatably connected in both connecting seats, and a bevel gear is fixedly installed on the end of each rotating shaft near the bevel gear, which meshes with the bevel gear.
[0007] Furthermore, the outer side of the second rotating shaft is provided with an external thread, and a threaded sleeve is threadedly connected to the second rotating shaft. A slider is fixedly installed on both threaded sleeves, and a guide rail adapted to the slider is provided on the moving end of the electric slide rail.
[0008] Furthermore, a brush is fixedly installed at the end of each of the two threaded sleeves away from the second rotating shaft.
[0009] The beneficial effects of this utility model are as follows: By setting up climbing components, the brushes can move up and down inside the cooling tower body. A telescopic assembly drives two brushes to move simultaneously towards the inner wall of the cooling tower body. An electric slide rail is installed at the junction of the two brushes and the inner wall, allowing the brushes to rotate axially along the center point of the slide rail, thereby removing dirt from the inner side of the cooling tower body. Compared with existing technologies, the two brushes can rotate axially along the center of the cooling tower body, regardless of the diameter of the cooling tower body, making it more versatile. Simultaneously, the climbing components can drive the brushes to different heights within the cooling tower body, further increasing the cleaning range of the brushes, thus increasing the service life of the cooling tower and ensuring cooling effect, making it more practical.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0017] In the embodiments, by Figure 1-3 A cooling tower descaling device is provided, comprising a cooling tower body 1, a climbing member 2 for moving up and down along the inner wall of the cooling tower body 1, a telescopic component 4 on the climbing member 2, and an electric slide rail 3 for driving the telescopic component 4 to rotate horizontally on the climbing member 2. The two telescopic ends of the telescopic component 4 are respectively provided with brushes 5. The electric slide rail 3 adopts a conventional model in the prior art and is circular in shape. Two moving blocks are provided on the electric slide rail 3.
[0018] Reference Figure 1-3 The climbing component 2 includes a ring 21. The ring 21 is provided inside the cooling tower body 1. Four electric push rods 22 are fixedly installed on the outer side of the ring 21, which are distributed in a ring at equal intervals around the center of the ring 21. Two electric push rods 23 are fixedly installed on the top of the ring 21. The moving ends of the two electric push rods 23 are fixedly connected to the circular plate 24. Four electric push rods 25 are fixedly installed on the outer side of the circular plate 24, which are distributed in a ring at equal intervals around the center of the circular plate 24. Support blocks 26 are fixedly installed on the telescopic ends of the electric push rods 22 and 25. A rubber anti-slip pad 27 is provided on one side surface of the support block 26.
[0019] With the above structural arrangement, when the electric push rod 1 22 and the electric push rod 3 25 extend outward, they can drive the support block 26 to move towards the inner wall of the cooling tower body 1 until the rubber anti-slip pad 27 is in contact with the inner wall of the cooling tower body 1, where it can be fixed. After the ring 21 is fixed, when the electric push rod 23 extends upward, the electric push rod 3 25 extends outward, thereby fixing the circular plate 24. When the electric push rod 1 22 retracts, the electric push rod 23 retracts accordingly, allowing it to move up and down along the height of the cooling tower body 1. The two electric push rods 22 23 are symmetrically arranged around the center of the ring 21, thereby increasing the stability of the ring 21 and the circular plate 24 during movement.
[0020] Reference Figure 1-3 The telescopic component 4 includes a bracket 41. The moving end of the electric slide rail 3 is provided with a bracket 41. A servo motor 42 is fixedly installed on the inner side of the bracket 41. A rotating shaft 43 is fixedly installed on the output end of the servo motor 42. A bevel gear 44 is fixedly installed on one end of the rotating shaft 43. The top of the ring 21 is fixedly installed with the electric slide rail 3. Two connecting seats 45 are fixedly installed on the electric slide rail 3. A rotating shaft 46 is rotatably connected inside each of the two connecting seats 45. A bevel gear 47 that meshes with the bevel gear 44 is fixedly installed on the end of each of the two rotating shafts 43 near the bevel gear 44.
[0021] With the above structural configuration, the servo motor 42 can drive the bevel gear 44 to rotate, and the bevel gear 47 meshing with the bevel gear 44 can rotate axially, thereby driving the two rotating shafts 46 to rotate within the connecting seat 45. The connecting seat 45 limits the rotating shafts 46 to prevent them from sliding, while also providing a certain support force. The two rotating shafts 46 will rotate under the drive of the electric slide rail 3, and will not come into contact with the two electric push rods 23.
[0022] Reference Figure 1-3 The outer side of the rotating shaft 46 is provided with an external thread, and a threaded sleeve 48 is threadedly connected to the rotating shaft 46. A slider 49 is fixedly installed on both threaded sleeves 48. A guide rail 410 adapted to the slider 49 is provided on the moving end of the electric slide rail 3.
[0023] With the above structural design, the outer side of the rotating shaft 46 is provided with an external thread. The length of the external thread is less than the length of the rotating shaft 46 and does not contact the connecting seat 45. When the rotating shaft 46 rotates, the threaded sleeve 48 can be driven to extend outward by the thread engagement. When the threaded sleeve 48 slides outward continuously, the slider 49 slides along the straight length of the guide rail 410, increasing the stability of the threaded sleeve 48 when it moves.
[0024] Reference Figure 1-3 Among them, a brush 5 is fixedly installed at the end of each of the two threaded sleeves 48 away from the rotating shaft 46;
[0025] With the above-mentioned structure, when the two threaded sleeves 48 expand in opposite directions at the same time, they can push the brush 5 to contact the inner wall of the cooling tower body 1. When the brush 5 rotates, it can clean the inner wall of the cooling tower body 1.
[0026] Working principle:
[0027] Step 1: Using lifting equipment such as hoisting tools, move this device to the top of the cooling tower body 1 and slowly move it downwards. After the circular plate 24 is completely inside the cooling tower body 1, activate the electric push rod 25 to push the rubber anti-slip pad 27 on the electric push rod 25 into contact with the inner wall of the cooling tower body 1. When the moving end of the electric push rod 25 can no longer extend, the device can be fixed inside the cooling tower body 1. Then, remove the lifting equipment.
[0028] Step 2: Activate electric push rod 23 to drive ring 21 to move away from circular plate 24. When ring 21 stops moving, activate electric push rod 22. The method and effect of electric push rod 25 are the same. Therefore, this device can be fixed at a certain height inside the cooling tower body 1.
[0029] Step 3: Turn on the servo motor 42 to drive the rotating shaft 43 to rotate. Relying on the meshing of the bevel gear 44 and the bevel gear 47, the two rotating shafts 46 are controlled to rotate, thereby driving the two threaded sleeves 48 to move in opposite directions. This controls the brush 5 to contact the inner wall of the cooling tower body 1. Turn on the electric slide rail 3 to drive the two brushes 5 to reciprocate around the center of the electric slide rail 3. The angle of each rotation must not exceed 175°, so that a certain height of the inner wall of the cooling tower body 1 can be cleaned.
[0030] Step 4: After cleaning, retract the brush 5, control the electric push rod 3 25 to retract, then control the electric push rod 23 to retract, the circular plate 24 moves towards the circular ring 21, control the electric push rod 23 to extend, fix the circular plate 24, then control the electric push rod 1 to retract, control the electric push rod 23 to extend outward, the circular ring 21 moves away from the circular plate 24, then control the electric push rod 1 22 to extend outward, thus climbing inside the cooling tower body 1 and changing the cleaning height of the brush 5.
