Description

Technical Field

[0001] This utility model relates to the technical field of spray cooling devices, specifically a spray cooling device for air-cooled systems in power plants. Background Technology

[0002] As is well known, spray cooling devices for air-cooled systems in power plants are key equipment used to reduce air temperature and improve air-cooling efficiency. By atomizing water into tiny particles, the system utilizes the principle of water evaporation and heat absorption to remove heat, thereby lowering the temperature of the air entering the air-cooling system.

[0003] The angle of the atomizing nozzles in existing spray cooling devices for air-cooled power plant systems is generally fixed, making it difficult to flexibly adjust the nozzle angle. This can easily lead to some areas not receiving sufficient spray coverage, resulting in excessively high local temperatures and affecting the overall cooling effect of the air-cooled system. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a spray cooling device for air-cooled systems in power plants.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a spray cooling device for an air-cooled system in a power plant, comprising a base plate, a housing, a cover plate, a spraying assembly, and an adjusting mechanism. The housing is disposed on top of the base plate. The cover plate is connected to the housing via a first electromagnet. The spraying assembly is connected to the cover plate via a first bolt. The spraying assembly is equipped with an atomizing nozzle. The adjusting mechanism includes a vertical plate, a circular plate, a cylinder, a clamping plate, a fixing block, a second bolt, a motor, and a square block. The vertical plate is fixedly connected to the top of the cover plate. One end of the cylinder is connected to the circular plate, and the other end of the cylinder passes through the vertical plate and is connected to the clamping plate. The clamping plate is in contact with the atomizing nozzle. The fixing block is connected to the vertical plate by the second bolt. One end of the motor is mounted on the fixing block, and the output end of the motor is connected to one end of the block. The other end of the block extends into the circular plate. There are two adjustment mechanisms. A controller is provided on the top of the cover plate. The controller is electrically connected to the motor. A pulley mechanism is provided at the bottom of the base plate. There are multiple pulley mechanisms.

[0008] To achieve the desired protective effect, this utility model is improved by providing a protective mechanism on the cover plate. The protective mechanism includes a protective shell, a long block, and a second electromagnet. The protective shell is connected to one end of the long block, and the other end of the long block is fixedly connected to one end of the second electromagnet.

[0021] 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.

[0022] Please see Figure 1-4 A spray cooling device for an air-cooled system in a power plant includes a base plate 1, a housing 2, a cover plate 3, a spraying assembly 5, and an adjusting mechanism 8. The housing 2 is located on top of the base plate 1. The cover plate 3 is connected to the housing 2 via a first electromagnet 4. The spraying assembly 5 is connected to the cover plate 3 via a first bolt 7. The spraying assembly 5 is equipped with an atomizing nozzle 6. The adjusting mechanism 8 includes a vertical plate 9, a circular plate 10, a cylinder 11, a clamping plate 12, a fixing block 13, a second bolt 14, a motor 15, and a square block 16. The vertical plate 9 is fixedly connected to the top of the cover plate 3. One end of the cylinder 11 is connected to the circular plate 10. The cylinder 11 is connected to the clamping plate 12 through the upright plate 9. The clamping plate 12 is in contact with the atomizing nozzle 6. The fixing block 13 is connected to the upright plate 9 by the second bolt 14. One end of the motor 15 is set on the fixing block 13. The output end of the motor 15 is connected to one end of the square block 16. The other end of the square block 16 extends into the circular plate 10. There are two adjusting mechanisms 8. The top of the cover plate 3 is equipped with a controller 17, which is electrically connected to the motor 15. The bottom of the base plate 1 is equipped with a pulley mechanism, and there are multiple pulley mechanisms.

[0023] Working principle:

[0024] The device is pushed and moved to a suitable position with the help of a pulley mechanism. The pulley mechanism adopts a universal wheel structure and is equipped with a brake assembly to fix the pulley. Then, the first electromagnet 4 is turned off so that it no longer attracts the box 2. The cover plate 3 is lifted upward to separate the cover plate 3 from the box 2. The water filtered by the external equipment is poured into the box 2, and then the first electromagnet 4 is used to merge the cover plate 3 with the box 2.

[0025] Activating the liquid extraction assembly can extract water from the tank 2 and atomize it through the atomizing nozzle 6 to a designated location. If it is necessary to adjust the spray angle of the atomizing nozzle 6, the motor 15 on the fixed block 13 can be activated through the controller 17. The motor drives the block 16 to rotate, which in turn causes the cylinder 11 on the circular plate 10 to drive the clamping plate 12 to rotate, thus achieving the adjustment of the angle of the atomizing nozzle 6.

[0026] The pulley mechanism at the bottom of the base plate 1 drives the entire equipment to move, which can adjust the spraying direction of the atomizing nozzle 6, thereby achieving spraying of different areas. The controller 17 can start the two motors 15 simultaneously and can adjust the speed and direction of the motors 15. The specific adjustment method will not be described in detail here.

[0027] It is worth mentioning that the spraying component 5 in the text includes a water pump, a liquid extraction pipe, and a folding hose. After the water pump in the spraying component is started, it draws water out of the box through the liquid extraction pipe. The water is then transported through the liquid extraction pipe to the folding hose. The folding hose can be flexibly bent according to the needs of the equipment usage scenario, and finally the water is transported to the atomizing nozzle 6 for atomization and spraying. The box 2 is made of martensitic stainless steel, so the first electromagnet 4 can attract the box 2.

[0028] The circular plate 10 in the text has a groove that matches the square block 16. The square block 16 rotates in the groove under the drive of the motor 15, thereby driving the circular plate 10 to rotate.

[0029] Disassembly work:

[0030] When the spraying assembly 5 or the atomizing nozzle 6 is damaged and needs to be repaired, the staff first use an external screwdriver to unscrew the first bolt 7 to release the fixation of the spraying assembly 5. Then, holding the fixing block 13, the staff uses a screwdriver to unscrew the second bolt 14. As the second bolt 14 is unscrewed, the fixing block 13 separates from the upright plate 9, and at the same time, the square block 16 of the motor 15 on the fixing block 13 will also separate from the round plate 10.

[0031] Then, hold the atomizing nozzle 6 and pull the circular plate 10 to move the cylinder 11 and the clamping plate 12, separating them from the atomizing nozzle 6. Finally, pull the spray assembly 5 upwards to separate the spray assembly 5 from the atomizing nozzle 6 from the equipment. It can then be sent to the manufacturer for repair.

[0032] In this structure, all parts that come into contact with each other and generate friction, such as the contact area between the circular plate 10 and the vertical plate 9, are coated with a ceramic coating. This ceramic coating not only provides excellent wear resistance but also reduces the coefficient of friction.

[0033] This structure requires power to be connected to an external device during use, and the power cord provided is of sufficient length to avoid affecting use due to insufficient power cord length.

[0034] In this embodiment, the cover plate 3 is provided with a protective mechanism 18, which includes a protective shell 19, a long block 20, and a second electromagnet 21. The protective shell 19 is connected to one end of the long block 20, and the other end of the long block 20 is fixedly connected to one end of the second electromagnet 21. The second electromagnet 21 attracts the vertical plate 9. When the equipment is not in use, the operation controller 17 starts the motor 15. The motor 15 rotates, causing the square block 16 to rotate, which in turn causes the circular plate 10 to rotate. During this process, the atomizing nozzle 6 rotates upward 90 degrees, accurately positioning itself directly above the protective shell 19. At this time, the device is turned off. The second electromagnet 21 is used to release the adsorption state from the vertical plate 9. Then, the protective shell 19 is carefully lifted to tightly cover the spray end of the atomizing nozzle 6. At this time, the second electromagnet 21 is located on the upper side of the vertical plate 9 and is still in contact with the vertical plate 9. When the second electromagnet 21 is activated again, it can firmly adsorb the vertical plate 9. Since the vertical plate 9 is made of martensitic stainless steel, it has good magnetic conductivity, which ensures that the second electromagnet 21 can be stably adsorbed. The effective protection of the spray end of the atomizing nozzle 6 by the protective shell 19 can effectively prevent external dust from clogging the atomizing nozzle 6 and ensure the normal spraying function of the equipment when it is used next time.

[0035] The above-mentioned equipment is inconvenient to operate. In order to solve this problem, in this embodiment, the controller 17 is electrically connected to the first electromagnet 4 and the controller 17 is electrically connected to the second electromagnet 21.

[0036] The cover plate 3 is inconvenient to lift. To solve this problem, in this embodiment, the top of the cover plate 3 is provided with a handle, and the handle is fixedly connected to the top of the cover plate 3.

[0037] The stability of the aforementioned adjustment mechanism 8 is poor. To solve this problem, in this embodiment, the two adjustment mechanisms 8 are arranged symmetrically.

[0038] In order to improve the adsorption effect between the cover plate 3 and the box 2, in this embodiment, the first electromagnet 4 is provided with several of them.

[0039] In this structural design, to ensure stable operation of the equipment in complex environments, the motor 15, the first electromagnet 4, and the second electromagnet 21 are all selected with excellent waterproof performance. These components have a waterproof rating of the highest standard IP8, which means that they can be submerged in water for a long time without being affected. Even in harsh working conditions with high humidity and high moisture content, they can ensure normal operation and effectively avoid failures or damage caused by water intrusion. It is worth mentioning that, in addition to its excellent waterproof capability, the motor 15 also has excellent anti-electromagnetic interference characteristics. During actual operation, the first electromagnet 4 and the second electromagnet 21 will generate a certain electromagnetic field. The motor 15, with its special anti-electromagnetic design, can effectively resist the interference of these electromagnetic fields, ensuring its own stable performance and avoiding abnormal operation due to electromagnetic interference, thus ensuring the reliable operation of the entire structure.

[0040] A waterproof sealing ring is provided between the cover plate 3 and the housing 2 in this structure, and a waterproof sealing ring is also provided between the spraying assembly 5 and the cover plate 3. This design greatly improves the waterproof performance of the device. At the connection between the cover plate 3 and the housing 2, the waterproof sealing ring fits tightly against the contact surface of the two, effectively filling the gap and preventing water from seeping into the interior of the housing 2. The waterproof sealing ring between the spraying assembly 5 and the cover plate 3 also plays a key role, preventing water from leaking from the connection between the spraying assembly 5 and the cover plate 3 during the spraying process, ensuring that the equipment can operate stably in humid environments or during water spraying operations. In terms of material selection for the waterproof sealing ring, aging-resistant and chemically corrosion-resistant rubber materials, such as EPDM rubber, are preferred. This rubber has good elasticity and flexibility, and can maintain good sealing performance even after long-term use. At the same time, its chemical resistance can resist the corrosion of chemical substances that may exist in the power plant environment, extending the service life of the waterproof sealing ring.

[0041] The dimensions and shapes of all components in this structure are not specifically limited here and need to be produced according to the actual situation. The control method of this utility model is controlled by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in this field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and wiring layout will not be explained in detail here.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
