Description

Technical Field

[0001] This utility model relates to the field of cooling tower descaling technology, specifically a descaling device for power plant cooling towers. Background Technology

[0002] Cooling towers are crucial facilities in the industrial sector for dissipating heat from operating equipment, widely used in power plants, chemical plants, steel mills, and other environments requiring efficient heat dissipation. Their core function is to transfer heat generated by industrial equipment to the air through a water circulation system, utilizing the evaporation of water to lower its temperature, thereby achieving heat exchange. A typical cooling tower structure includes components such as a packing layer, a water collection tray, and a fan. The inner walls and packing surfaces are in constant contact with the circulating water, making them prone to scale formation due to the deposition of calcium and magnesium ions, microbial growth, and rust adhesion.

[0003] The efficient operation of cooling towers is crucial for industrial production: decreased heat dissipation efficiency can lead to equipment overheating, increased energy consumption, or even shutdown. However, scale buildup over long-term operation significantly reduces heat exchange efficiency, increases fan energy consumption, and accelerates corrosion of metal components, ultimately resulting in increased maintenance costs and shortened equipment lifespan. Therefore, regular descaling is one of the core tasks of cooling tower operation and maintenance.

[0004] Calcium and magnesium ions in the circulating water of cooling towers easily combine with carbonate ions at high temperatures to form scale such as calcium carbonate and magnesium carbonate. Simultaneously, metabolic products of microorganisms (such as algae and bacteria) and rust produced by system corrosion also adhere to the inner walls. These deposits reduce heat exchange efficiency, increase energy consumption, and exacerbate corrosion. Traditional descaling methods have limitations: they rely on manual climbing into the tower to remove scale using brushes, scrapers, and other tools, making it difficult to cover the top area. Each cleaning session takes hours to days, and working at height carries the risk of falls. Contact with chemicals (such as pickling solutions) can cause burns. Manual operation makes precise pressure control difficult, easily overlooking uneven surfaces or narrow areas, leading to scale recurrence. Existing automation technologies are also insufficient: most equipment only achieves single-axis movement (such as rotation or lifting), lacking multi-degree-of-freedom linkage, resulting in limited cleaning coverage. Therefore, designing a practical and multi-degree-of-freedom linkage descaling device for power plant cooling towers is essential. Utility Model Content

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-6 This utility model provides a technical solution: a descaling device for power plant cooling towers, comprising:

[0033] The center seat 1 has at least three telescopic rods 4 with edge support plates 5 arranged in a circular array on its outer side. A pressure sensor 6 is provided between the telescopic rods 4 and the edge support plates 5.

[0034] Cleaning seat 2 is mirror-symmetrically arranged at the top and bottom of the central seat 1 and is rotatably connected to the central seat 1 via a rotation drive mechanism 3. The side wall of the cleaning seat 2 is circumferentially arranged with at least three telescopic rods 8 with cleaning plates 9.

[0035] Control component 7 and control component 10 are used to adjust the extension and retraction of telescopic rod 4 and telescopic rod 8, respectively.

[0036] A lifting control component 11 is mounted on the edge support plate 5 and is used to drive the device to move along the height direction of the cooling tower.

[0037] The central seat 1 is the core support structure of the device. It contacts the inner wall of the cooling tower via the outer array of telescopic rods 4 and edge support plates 5, ensuring stable positioning within the tower. Pressure sensors 6 monitor the contact pressure between the telescopic rods 4 and the tower wall, and control components 7 adjust the length of the telescopic rods 4 in real time to ensure appropriate pressure during cleaning, preventing damage to the tower wall from excessive pressure or incomplete cleaning due to insufficient contact. The telescopic rods 4 can automatically adjust according to the diameter and shape of the cooling tower's inner wall, adapting to different specifications of cooling towers. Cleaning seats 2 are mirror-symmetrically positioned at the top and bottom of the central seat 1. A rotary drive mechanism 3 rotates the cleaning seats 2, allowing the cleaning plates 9 to cover the entire circumference, achieving 360-degree cleaning without dead angles. The top and bottom cleaning seats can simultaneously clean the upper and lower areas of the tower wall, improving efficiency. The rotating design quickly removes scale adhering to the tower wall, making it suitable for power plants, chemical plants, and large industrial cooling systems in highly corrosive and high-temperature environments. In scaling environments, the telescopic rod 8 adjusts its extension and retraction via control component 10, controlling the distance between the cleaning plate 9 and the tower wall. This adapts to uneven surfaces or areas with severe scaling on the tower wall. The cleaning plate 9 integrates physical brushes or scrapers to directly remove scale. Optional descaling liquid spraying devices (such as acidic or enzymatic agents) can be added to soften stubborn scale before mechanical removal. The cleaning plate 9 is fixed in place with bolts and can be made of different materials (such as hard alloy or flexible brush heads) to adapt to different scaling types (such as calcium magnesium scale or rust). Cooling towers are generally designed to be narrow in the middle and wide at both ends. The lifting control component 11 on the edge support plate 5 drives the device to move along the height of the cooling tower, covering the entire height inside. Guide rails corresponding to the lifting control component 11 can be configured to ensure the stability of lifting. Cleaning from bottom to top can be completed automatically without manual climbing, reducing the risk of manual high-altitude operations and improving maintenance efficiency.

[0038] Specifically, the rotary drive mechanism 3 includes a central drive shaft 301, a servo motor 302, a transmission gear 303, and a transmission gear 304. The central drive shaft 301 is movably mounted in the middle position of the central seat 1 via bearings. The two ends of the central drive shaft 301 are respectively fixedly connected to the cleaning seat 2. The servo motor 302 is fixed at the lower end of the central seat 1. The transmission gear 303 is fixedly connected to the output end of the servo motor 302. The transmission gear 304 is fixedly sleeved on the central drive shaft 301. The transmission gear 303 meshes with the transmission gear 304.

[0039] Servo motor 302 drives transmission gear 303 to rotate via output shaft. Transmission gear 304 meshing with it is fixed on central drive shaft 301, thereby driving central drive shaft 301 to rotate. Cleaning seats 2 are fixed at both ends of central drive shaft, driving the cleaning seats to rotate synchronously, so that cleaning plate 9 evenly covers the inner wall of cooling tower for cleaning.

[0040] Specifically, the telescopic rod 4 includes a fixed cylinder 401, a movable block 402, a fixed rod 403, and a threaded rod 404. The fixed cylinder 401 is fixed to the side wall of the center seat 1 and has a square guide groove inside. The movable block 402 has a square cross-section and slides with the guide groove. One end of the movable block 402 is fixed to the fixed rod 403, and the other end is threaded to the threaded rod 404. The threaded rod 404 is fixed to the end of the fixed cylinder 401 by a bearing.

[0041] The threaded rod 404 is rotated by the control component 7. The threaded connection between the threaded rod 404 and the movable block 402 causes the movable block 402 to move along the thread direction (forward or backward). The movable block 402 moves linearly in the square guide groove, which drives the fixed rod 403 and the edge support plate 5 to extend or retract, thus completing the telescopic function.

[0042] Specifically, the control component 7 includes a servo motor 701, a transmission gear 702, a movable ring 703, a bevel gear 704, a bevel gear 705, and an annular rack 706. The servo motor 701 is fixedly installed at the upper edge of the center seat 1. The output end of the servo motor 701 extends into the center seat 1 and is fixedly installed with the transmission gear 702. The movable ring 703 is movably installed inside the center seat 1. The bevel gear 704 is provided on the outer wall of the movable ring 703. The bevel gear 705, which meshes with the bevel gear 704, is fixedly installed at the end of the threaded rod 404. The annular rack 706, which meshes with the transmission gear 702, is fixedly installed on the inner wall of the movable ring 703.

[0043] Servo motor 2 701 rotates and drives transmission gear 3 702. Transmission gear 3 702 meshes with the ring rack 706 of movable ring 703, causing movable ring 703 to rotate around the axis of central seat 1. The bevel gear 1 704 on the outer wall of movable ring 703 meshes with bevel gear 2 705 at the end of telescopic rod 1 4, transmitting the rotation to threaded rod 1 404. The rotation of threaded rod 1 404 drives movable block 1 402 to move along fixed cylinder 401, completing the telescopic action of telescopic rod 1.

[0044] Specifically, the telescopic rod 8 includes a movable cylinder 801, a movable block 802, a spring 803, a fixed rod 804, and a threaded rod 805. The movable cylinder 801 is fixed to the side wall of the cleaning seat 2 and has a square guide groove inside. The movable block 802 has a square cross-section and slides with the guide groove. The spring 803 is fixed to one end of the movable block 802 near the cleaning seat 2, and the fixed rod 804 is fixed to the other end. The end of the fixed rod 804 is connected to the cleaning plate 9. The threaded rod 805 is threaded inside the movable cylinder 801. The spring 803 is used to buffer the contact pressure between the cleaning plate 9 and the inner wall of the cooling tower.

[0045] The control component 10 drives the threaded rod 805 to rotate. The threaded connection between the threaded rod 805 and the movable block 802 drives the movable block 802 to move along the guide groove (forward or backward). The movable block 802 drives the fixed rod 804 and the cleaning plate 9 to extend and retract. At the same time, the spring 803 buffers the contact pressure between the cleaning plate 9 and the inner wall in real time to prevent overload. The spring 803 absorbs the contact pressure in real time to protect the inner wall of the cooling tower and the cleaning plate 9, avoiding scratches or deformation of the cleaning plate 9 caused by hard contact. The elasticity of the spring 803 can keep the cleaning plate 9 under uniform pressure on the irregular inner wall surface, improving the cleaning effect.

[0046] Specifically, the control component 2 10 includes a servo motor 3 1001, a bevel gear 3 1002, and a bevel gear 4 1003. The servo motor 3 1001 is fixed inside the cleaning seat 2, and its output end is directly fixed to the bevel gear 4 1003. The bevel gear 4 1003 meshes with the bevel gear 3 1002 at the end of the threaded rod 2 805 to drive the threaded rod 2 805 to rotate.

[0047] Servo motor 31001 rotates and drives bevel gear 41003. Bevel gear 41003 meshes with bevel gear 31002, transmitting rotation to threaded rod 2805. Threaded rod 2805 rotates and drives movable block 802 to move along the thread of movable cylinder 801, thereby controlling the extension or pressure of cleaning plate 9.

[0048] Specifically, the lifting control component 11 includes a movable shaft 1101, a moving wheel 1102, and a servo motor 1103. The edge support plate 5 has symmetrical guide rail grooves. The moving wheel 1102 is movably mounted in the guide rail groove through the movable shaft 1101. The servo motor 1103 is fixed to the side wall of the edge support plate 5, and its output end is fixedly connected to the movable shaft 1101. By driving the movable shaft 1101 to rotate, the moving wheel 1102 moves up and down along the guide rail groove to adjust the height of the device.

[0049] The output shaft of servo motor 4 1103 rotates, driving the movable shaft 1101 to rotate synchronously. The movable shaft 1101 converts the rotational motion into linear motion of the moving wheel 1102 in the guide rail groove. The moving wheel 1102 moves up and down along the guide rail groove, driving the edge support plate 5 and the whole unit to rise and fall. By controlling the rotation direction and number of revolutions of servo motor 4 1103, the height of the device can be precisely adjusted to meet the cleaning needs of different heights of the inner wall of the cooling tower (such as the top packing layer or the bottom water collection tray).

[0050] Working Principle: This device is an automated, multi-degree-of-freedom linkage cooling tower descaling equipment. Through the combination of mechanical structure and intelligent control, it achieves full-height and full-circumference cleaning of the inner wall of the cooling tower. Its core components include: Central base 1: the core support structure of the device, connecting the telescopic rod 4 and the edge support plate 5, and the contact pressure with the inner wall of the cooling tower is monitored in real time by pressure sensor 6.

[0051] Cleaning seat 2: symmetrically positioned at the top and bottom of the central seat, the cleaning plate 9 is rotated by the rotation drive mechanism 3 to achieve 360-degree cleaning without dead angles.

[0052] Telescopic rod 4 and control component 7: Adjust the contact pressure and positioning between the device and the inner wall of the cooling tower to adapt to cooling towers of different diameters.

[0053] Telescopic rod 28 and control component 210: control the telescopic amount and contact pressure of cleaning plate 9 to adapt to irregular inner wall surfaces.

[0054] Lifting control component 11: The drive unit moves along the height of the cooling tower to cover the entire cleaning range of the tower.

[0055] The detailed workflow is as follows:

[0056] S1, Initial Positioning: After the device is placed in the cooling tower, the control component 7 drives the telescopic rod 4 to extend and retract automatically, so that the edge support plate 5 contacts the inner wall. The pressure sensor 6 adjusts the pressure to the preset value in real time to ensure stable positioning.

[0057] S2, Rotary cleaning start: Servo motor 302 starts, driving the cleaning seat 2 to rotate, and the cleaning plate 9 moves along the inner wall circumferentially to remove the attached scale.

[0058] S3, Dynamic pressure adjustment: If there is severe local scaling or irregular shape on the inner wall, the pressure sensor 6 triggers the control component 10, which drives the telescopic rod 8 to extend or shorten, and the cleaning plate 9 maintains uniform pressure through the spring 803.

[0059] S4, Lifting and Moving: Servo motor 4103 drives lifting control component 11. The device moves along the height direction of the cooling tower to cover the entire tower cleaning range. After each layer is cleaned, it automatically rises to the next height segment.

[0060] S5, Cycle and Termination: The device repeats the "positioning, rotation, lifting" process until the entire tower is cleaned. After cleaning, the telescopic rod is retracted and the device is removed from the cooling tower.
