Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, specifically to an intelligent cleaning device for locomotive cooling tower radiators. Background Technology

[0002] As a core component of the locomotive cooling system, the cooling tower plays a crucial role in dissipating heat from critical equipment such as traction transformers and traction converters. However, in actual operation, the frequent occurrence of high-temperature alarms in the cooling towers has become one of the major problems plaguing railway operations.

[0003] According to on-site investigations, the main reasons for frequent high-temperature alarms in locomotive cooling towers are: Cooling tower radiators accumulate large amounts of pollutants such as coal ash, dust, rail wear particles, and insect carcasses on their surfaces and internal channels, especially along freight lines and in sections passing through mining and industrial areas. These pollutants not only clog the ventilation gaps of the radiator fins but also form a hard-to-remove caked layer. If not cleaned in time, this can lead to a significant decrease in the radiator's heat dissipation efficiency, which in turn can cause a chain reaction of problems such as increased coolant temperature, system overheating, and high-temperature alarms.

[0020] Example 1 like Figures 1 to 4 As shown, this embodiment provides an intelligent cleaning device for locomotive cooling tower radiators. The cooling tower 1 includes a tower body 1.1, a radiator 1.2, and an auxiliary oil tank 1.3. The radiator 1.2 has a shielded area 1.2.1 and an unshielded area 1.2.2. The shielded area 1.2.1 is located below the auxiliary oil tank 1.3. The intelligent cleaning device for locomotive cooling tower radiators includes a fixed cleaning module 2, a mobile cleaning module 3, and an intelligent control module 4. The fixed cleaning module 2 is located in the gap between the radiator 1.2 and the auxiliary oil tank 1.3. The mobile cleaning module 3 is located in the unshielded area between the radiator 1.2 and the auxiliary oil tank 1.3. The intelligent control module 4 is electrically connected to the mobile cleaning module 3 and can control the mobile cleaning module 3 to move and clean the unshielded area 1.2.2 of the radiator 1.2. The fixed cleaning module 2 is positioned in the gap between the radiator 1.2 and the auxiliary oil tank 1.3, and can effectively clean the obstructed area 1.2.1 of the radiator 1.2 located below the auxiliary oil tank 1.3. The mobile cleaning module 3 is positioned in the unobstructed area 1.2.2 of the radiator 1.2, and the intelligent control module 4 can control the mobile cleaning module 3 to move and clean in the unobstructed area 1.2.2 of the radiator 1.2, thereby achieving effective cleaning of the radiator 1.2 and effectively solving the problem of low ventilation and heat dissipation efficiency caused by contaminants clogging the ventilation gap.

[0021] The mobile cleaning module 3 includes a drive motor 3.1, a cleaning water pipe 3.2, and wheels 3.3. The drive motor 3.1 is mounted on the tower body 1.1. The cleaning water pipe 3.2 is connected to the output shaft of the drive motor 3.1, enabling the drive motor 3.1 to drive the cleaning water pipe 3.2 to rotate in a horizontal plane. The cleaning water pipe 3.2 is connected to a water supply device and has multiple nozzles 5 spaced apart in a straight line. The wheels 3.3 are mounted on the cleaning water pipe 3.2, allowing it to move on the radiator 1.2. The water supply device supplies water to the cleaning water pipe 3.2, which then rinses the radiator 1.2 below through the nozzles 5. Simultaneously, the cleaning water pipe 3.2 rotates in a horizontal plane via the wheels 3.3 under the action of the drive motor 3.1, expanding the cleaning range and effectively cleaning the dirt and blockages on the radiator 1.2. In this embodiment, the cleaning water pipe 3.2 is provided with an inlet 3.2.1 that is connected to the water supply equipment.

[0022] Specifically, the mobile cleaning module 3 also includes a limiting mounting base 3.4, a rotating connecting block 3.5, a first limit switch 3.9, and a second limit switch 3.10. The limiting mounting base 3.4 is mounted on the tower body 1.1 and has a through hole. The output shaft of the drive motor 3.1 passes through the through hole and connects to the rotating connecting block 3.5. The rotating connecting block 3.5 is fixedly sleeved on the cleaning water pipe 3.2. The first limit switch 3.9 and the second limit switch 3.10 are set at an angle to the limiting mounting base 3.4 facing the rotation. One side of the connecting block 3.5, and the first limit switch 3.9 and the second limit switch 3.10 are electrically connected to the drive motor 3.1 respectively. The first limit switch 3.9 can control the start and stop of the drive motor 3.1, and the second limit switch 3.10 can control the direction of the drive motor 3.1. The rotating connecting block 3.5 is located between the first limit switch 3.9 and the second limit switch 3.10, and the drive motor 3.1 can drive the rotating connecting block 3.5 to rotate back and forth between the first limit switch 3.9 and the second limit switch 3.10.

[0023] Furthermore, both the first limit switch 3.9 and the second limit switch 3.10 have elastic plates on the side facing the rotating connecting block 3.5. When the moving cleaning module 3 is not started, the rotating connecting block 3.5 is pressed against the elastic plate of the first limit switch 3.9. After the moving cleaning module 3 is started, the drive motor 3.1 drives the rotating connecting block 3.5 to rotate away from the elastic plate of the first limit switch 3.9 until it comes into contact with the elastic plate of the second limit switch 3.10, thereby triggering the second limit switch 3.10. The second limit switch 3.10 sends a signal to control the drive motor 3.1 to drive the rotating connecting block 3.5 to rotate in the opposite direction until it comes into contact with the elastic plate of the first limit switch 3.9, thereby triggering the first limit switch 3.9. The first limit switch 3.9 sends a signal to control the drive motor 3.1 to turn off. The first limit switch 3.9 and the second limit switch 3.10 limit the rotation of the rotating connecting block 3.5 and also control the start, stop and direction of the drive motor 3.1, so as to achieve precise control of the rotation angle of the cleaning water pipe 3.2 in the mobile cleaning module 3.

[0024] In this embodiment, the drive motor 3.1 drives the cleaning water pipe 3.2 to rotate via the rotating connecting block 3.5, thereby enabling cleaning of the fan-shaped area centered on the rotating connecting block 3.5. The included angle between the first limit switch 3.9 and the second limit switch 3.10 corresponds to the arc angle of the fan-shaped area. Furthermore, the spray area 6 of the nozzles 5 at one or both ends of the cleaning water pipe 3.2 away from the rotating connecting block 3.5 is 2-3 times larger than the spray area 6 of the other nozzles 5, ensuring effective cleaning of the radiator 1.2 outside the fan-shaped area. The nozzles 5 spray vertically downwards, preventing irregular rinsing by operators using water guns, which could cause the radiator 1.2 fins to collapse.

[0025] Furthermore, the mobile cleaning module 3 also includes a fixed connecting block 3.6 and a de-energized electromagnet 3.7. The fixed connecting block 3.6 is mounted on the cleaning water pipe 3.2, and the traveling wheel 3.3 is mounted on the fixed connecting block 3.6. The de-energized electromagnet 3.7 is mounted on the tower body 1.1, and the de-energized electromagnet 3.7 can attract or release the fixed connecting block 3.6 to limit or unlock the cleaning water pipe 3.2. The magnetic attraction between the de-energized electromagnet 3.7 and the fixed connecting block 3.6 limits the cleaning water pipe 3.2 to prevent it from shaking due to vehicle vibration during locomotive movement, reducing damage to the mobile cleaning module 3 caused by shaking. It also forms a double rotation angle protection with the first limit switch 3.9 and the second limit switch 3.10, which helps to improve structural stability and extend service life.

[0026] See Figure 5There are two mobile cleaning modules 3, which are respectively located on both sides of the radiator 1.2 in the width direction. The two mobile cleaning modules 3 are located on both sides of the unshielded area 1.2.2 to ensure effective cleaning of the unshielded area 1.2.2. In this embodiment, the fixed pipe section of the fixed cleaning module 2 includes multiple pipes of different lengths. Each pipe is arranged in order of length from longest to shortest from the inside out, and the first end of each pipe is arranged on the same straight line. The two movable cleaning modules 3 are arranged symmetrically on both sides of the unshielded area 1.2.2, and the rotating connecting block 3.5 is arranged at the end of the corresponding cleaning water pipe 3.2. The two movable cleaning modules 3 are arranged diagonally on the unshielded area 1.2.2, and the end of the cleaning water pipe 3.2 away from the rotating connecting block 3.5 extends along the length direction of the radiator 1.2 to the edge of the unshielded area 1.2.2. The rotating connecting block 3.5 on the side closer to the fixed cleaning device is arranged close to the first end of the pipe with a rotation angle of 115°, and the other rotating connecting block 3.5 has a rotation angle of 90°. While expanding the cleaning area corresponding to the movement trajectory 3.8, the arrangement area of ​​the fixed cleaning device can be reduced, and the cleaning area accounts for 95%.

[0027] In this embodiment, the fixed cleaning device includes a fixed pipe fitting 2.1 and a fixed support block 2.2. The fixed pipe fitting 2.1 is connected to the water supply equipment, and the fixed pipe section is equipped with multiple arrayed nozzles 5. The fixed pipe fitting 2.1 is connected to the auxiliary oil tank 1.3 or the tower body 1.1 through two or more fixed support blocks 2.2. The fixed cleaning device is fixedly installed in the shielded area 1.2.1 of the radiator 1.2 below the auxiliary oil tank 1.3, effectively solving the problem of narrow cleaning space below the auxiliary oil tank 1.3.

[0028] In addition, the intelligent control module 4 includes an intelligent rotating camera 4.1, a wind speed monitor 4.2, and a controller. The intelligent rotating camera 4.1 is installed on the tower body 1.1 above the radiator 1.2 and is used to capture images of the surface of the radiator 1.2. The wind speed monitor 4.2 is installed on the tower body 1.1 and is used to measure the wind speed of the fan 1.4 on the tower body 1.1 at full speed. The controller is electrically connected to the water supply equipment, the intelligent rotating camera 4.1, the wind speed monitor 4.2, and the mobile cleaning module 3. The intelligent rotating camera 4.1 can monitor the surface of the radiator 1.2 in real time and upload the image to the AI ​​large model to identify dirt and blockages (coal ash, dust, rail wear particles, and insect corpses). When the wind speed monitor 4.2 is running at full speed with the fan 1.4, if the wind speed is ≤8m / s, it is determined that the radiator 1.2 is blocked and needs cleaning; if the wind speed is ≥12m / s, it is determined that the radiator 1.2 has been cleaned. (It can intelligently track the dirt and blockage status of the radiator 1.2 of the cooling tower 1 in real time, effectively solving the problem of poor heat dissipation leading to coolant temperature alarms. The AI ​​large model in this embodiment adopts an existing AI intelligent recognition model.)

[0029] Example 2 The difference from Example 1 is as follows: See Figure 6 The pipes in the fixed fitting 2.1 are all the same length; the drive motors 3.1 in the two moving cleaning modules 3 are both located at the midpoint of the two sides of the unobstructed area 1.2.2, and the rotation angle of the rotating connecting block 3.5 is 180°. The length of the cleaning water pipe 3.2 is 0.5 times the length of the cleaning water pipe 3.2 in Example 1. The shortening of the length of the cleaning water pipe 3.2 is beneficial to reduce the flow and pressure of the water pump and air pump, and also facilitates later maintenance.

[0030] Example 3 The difference from Example 2 is as follows: See Figure 7 In both movable cleaning modules 3, the rotation angle of the rotating connecting block 3.5 is 115°, and the length of the cleaning water pipe 3.2 is shortened accordingly based on the actual dimensions. This embodiment can ensure a sufficient cleaning area.

[0031] Example 4 The difference from Example 2 is as follows: See Figure 8In one embodiment, the drive motor 3.1 of the mobile cleaning module 3 is positioned at the midpoint of the unobstructed area 1.2.2 near the fixed cleaning module 2. The rotation angle of the rotating connecting block 3.5 is 180°, and the length of the cleaning water pipe 3.2 is 0.5 times the length of the cleaning water pipe 3.2 in embodiment 1. The rotating connecting block 3.5 of the other mobile cleaning module 3 is positioned at the end point of the unobstructed area 1.2.2 near the fixed cleaning module 2, with a rotation angle of 90°. The length of the cleaning water pipe 3.2 is the same as that in embodiment 1. This embodiment ensures a sufficient cleaning area.

[0032] Example 5 The difference from Example 2 is as follows: See Figure 9 One movable cleaning module 3 is arranged along the length of the radiator 1.2, with the rotating connecting block 3.5 rotating at an angle of 90°. The length of the cleaning water pipe 3.2 is the same as that in Embodiment 1. Another movable cleaning module 3 is arranged along the width of the radiator 1.2, and is located away from the fixed cleaning module 2. The rotating connecting block 3.5 rotates at an angle of 115°, and the length of the cleaning water pipe 3.2 is shortened accordingly based on the actual dimensions. In this embodiment, the cleaning movement trajectory 3.8 area is enlarged, facilitating later maintenance. The installation of the fixed connecting block 3.6 will not damage the auxiliary oil tank 1.3 or cause oil leakage.

[0033] Example 6 See Figure 10 This embodiment provides a control method for an intelligent cleaning device for locomotive cooling tower radiators, controlling the intelligent cleaning device to clean radiator 1.2, including the following steps: A smart rotating camera 4.1 is used to capture images of the surface of the radiator 1.2 in real time, and an existing AI intelligent recognition model is used to identify the area covered by dirt and blockage in the image. The wind speed of fan 1.4 at full-frequency speed was measured using an anemometer 4.2. If the area coverage rate of the dirt blockage exceeds a first preset threshold or the wind speed is lower than a second preset threshold, the intelligent cleaning device for the locomotive cooling tower radiator is activated to clean the radiator 1.2 until the wind speed measured by the wind speed monitor 4.2 exceeds the second preset threshold; where: dirt blockage area coverage rate = dirt blockage coverage area / radiator surface area. In this embodiment, the first preset threshold is 20%, and the second preset threshold is 8 m / s.

[0034] The intelligent cleaning device for the locomotive cooling tower radiator is activated to clean radiator 1.2, specifically including: Step ①: Start the water supply equipment on the locomotive to supply water to the fixed cleaning module 2 to clean the obstructed area 1.2.1; In this embodiment, the water supply equipment supplies water to the fixed cleaning module 2 for 1 minute; Step 2: The controller energizes the de-energized electromagnet 3.7 in the mobile cleaning module 3, causing the de-energized electromagnet 3.7 to lose its magnetic force and unlock the mobile cleaning module 3; Step 3: Start the water supply equipment on the locomotive to supply water to the unlocked mobile cleaning module 3. At the same time, the controller controls the cleaning water pipe 3.2 of the mobile cleaning module 3 to complete a back-and-forth rotation to clean the unobstructed area 1.2.2 corresponding to the movement trajectory of the mobile cleaning module 3. Step 4: The controller de-energizes the de-energized electromagnet 3.7 in the unlocked mobile cleaning module 3. The de-energized electromagnet 3.7 obtains magnetic force and limits the unlocked mobile cleaning module 3 through the adsorption and fixing connection block 3.6. Step 5: The controller energizes the de-energized electromagnet 3.7 in the other mobile cleaning module 3, causing the de-energized electromagnet 3.7 to lose its magnetic force and unlock the mobile cleaning module 3; Step 6: Start the water supply equipment on the locomotive to supply water to the unlocked mobile cleaning module 3. At the same time, the controller controls the cleaning water pipe 3.2 of the mobile cleaning module 3 to complete a back-and-forth rotation to clean the unobstructed area 1.2.2 corresponding to the movement trajectory of the mobile cleaning module 3. Step 7: The controller de-energizes the de-energized electromagnet 3.7 in the unlocked mobile cleaning module 3. The de-energized electromagnet 3.7 obtains magnetic force and limits the mobile cleaning module 3 through adsorption and fixing connection block 3.6.

[0035] The cleaning water pipe 3.2 of the mobile cleaning module 3 takes 2-3 minutes to complete one round-trip rotation; after step ⑦, the following steps are also included: if the wind speed measured by the wind speed monitor 4.2 is higher than the third set threshold, then cleaning is stopped; otherwise, steps ① to ⑦ are repeated, and the third set threshold is 12 m / s.

[0036] Since the control method for the intelligent cleaning device for locomotive cooling tower radiators includes the intelligent cleaning device for locomotive cooling tower radiators as described above, the control method for the intelligent cleaning device for locomotive cooling tower radiators possesses all the beneficial effects of the intelligent cleaning device for locomotive cooling tower radiators as described above, which will not be elaborated here.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
