Description

Technical Field

[0001] The present invention relates to the technical field of electric power industry cleaning, and in particular to an air cooler flushing device for a converter station. Background Art

[0002] Currently, the development of ultra-high voltage (UHV) and ultra-high voltage (EHV) equipment stations is a major trend in energy development. Converter valves play a crucial role in DC transmission projects. During the transmission process, converter valves generate significant heat. To ensure the safe and reliable operation of converter equipment, cooling technology is required to reduce this heat.

[0003] The converter valve cooling system consists of internal and external cooling systems. The internal cooling system removes heat through a closed loop, while the external cooling system is divided into water cooling and air cooling. Air cooling is noisy and inefficient. In contrast, using water as a medium has a heat transfer coefficient approximately 150 times that of air and provides stable operation. In areas with severe water shortages, water cooling systems are difficult to implement on a large scale. In these areas, air cooling is the only option. However, air cooling also presents several challenges. Due to frequent sandstorms and the presence of large amounts of dust and impurities in the air, the fin-tube heat exchangers commonly used in air cooling systems are prone to fouling. This fouling can clog the flow channels, causing the fan to operate in high static pressure and high vibration ranges for extended periods, resulting in stator and rotor scuffing, insulation failure, frequent fan burnouts, or tripping, significantly impacting the safe and reliable operation of the converter system.

[0004] Therefore, regular cleaning of fin-tube heat exchangers is very important for the normal operation of the converter station. Existing cleaning methods mainly include physical cleaning and chemical cleaning. Among them, physical cleaning is done manually by using a handheld high-pressure water gun. This method has the following problems:

[0005] (1) Although most dust and dirt can be removed, the fin spacing of the finned tube is only 2mm and the overall height is 4m, which makes it difficult for the high-pressure water flow to effectively clean the dirt in the edge gaps, resulting in incomplete cleaning;

[0006] (2) It consumes a lot of water and relies on the impact of water to flush out greasy substances and inorganic salt scale, which requires a long time to flush. It cannot be used in areas where water is scarce;

[0007] (3) Workers need to hold a high-pressure water gun for a long time and look up to flush the bottom of the 4m high air-dispersed fin tube. This is a heavy burden on the workers, and it not only consumes manpower, material resources and water resources, but also has low efficiency.

[0008] Chemical cleaning has the following problems:

[0009] (1) Chemical cleaning removes scale slowly and may cause corrosion to the pipeline;

[0010] (2) There is a lot of cleaning waste liquid, the treatment cost is high, and it is easy to cause environmental accidents.

[0011] (3) During the cleaning process, it is inevitable that the cleaning fluid will splash and overflow, causing safety hazards. Summary of the Invention

[0023] Compared with the related art, the present invention has the following beneficial effects:

[0024] 1. The present invention realizes the cleaning of dirt at the bottom of the fin tube when the air-cooling island drainage fan is placed on top

[0025] Existing industrial cleaning solutions and equipment primarily target air-cooled islands with bottom-mounted exhaust fans. With this design, the fans are placed at the bottom of the finned tubes, where dirt accumulates on top. This area also provides ample space for existing spray equipment to perform spraying operations. However, with top-mounted exhaust fans, the exhaust fans are located above the island and covered with extensive sheet metal. This makes it difficult to use existing spray equipment without removing the fans, which in turn significantly increases the workload and slows down cleaning efficiency.

[0026] In response to the above problems, the present invention improves and upgrades the spray equipment. The current spray equipment, which has multiple nozzles installed on the side of a pipe, is improved to a form with multiple micro-sprinklers. The new spray equipment is integrated with a collection device, so that the spray equipment can perform spray cleaning operations when the drainage fan is placed on the structure.

[0027] 2. The present invention realizes the integrated and portable design of the spray device and the collection device in the field of industrial cleaning

[0028] In the existing industrial cleaning field, the spray device and the collection device are separate. The equipment needs to be assembled when in use, and the movement of the equipment is also relatively inconvenient. The spray device does not move with the collection device. The equipment needs to be disassembled after use, and the process is cumbersome.

[0029] The present invention further optimizes and improves the structure of the spray equipment and the collection device (collection hood) used in industrial cleaning. Through the design of the trolley frame, the selection and control of the power source of the lifting device, the size constraint and installation design of the water tank and the hydraulic pump, the spray device, the collection device and the lifting device are organically integrated on the same trolley under limited size conditions, so that the spraying and flushing work can be carried out and used quickly, the movement is fast, and the cleaning efficiency is effectively improved.

[0030] 3. The present invention adds a limit design for the spray device

[0031] Currently, the limit design has not been introduced in the air-cooling island fin tube cleaning device. The reasons are as follows: the old collection device did not use a lifting device, resulting in a low cleaning agent collection rate. The new cleaning device lifting device is only used to lift the collection device, and the spray device is still independent. The limit device only has a safety function, but workers can rely on it to leave a large margin, so it is not taken seriously.

[0032] In the present invention, the spray device and the collecting hood are organically combined. The normal operation of the spray device requires a certain distance between the nozzle and the fin tube, and this distance will affect the spray cleaning effect. Therefore, a limiting device (limiting screw) is added to the spray device to control the lifting height. On the one hand, it can avoid the collision between the spray device and the fin tube. On the other hand, it can make the spray device in the optimal working range, effectively improving the spraying effect.

[0033] 4. Water level alarm device

[0034] This device is designed to be lightweight and convenient, with the water tank at the bottom of the device so that workers can add cleaning agents in time. This can make the water tank capacity smaller than that of previous industrial spray equipment. However, it is necessary to pay attention to the liquid level in the water tank during use. To further reduce the burden on workers, this device has a liquid level alarm device in the water tank. When the liquid level in the water tank is lower than the set value, a buzzer sounds to remind workers to add cleaning agents to the water tank.

[0035] 5. Design of sprinkler head swing device

[0036] The existing spray device is in a static state as a whole when working, and the spraying range of the nozzle remains unchanged for a long time, which is not conducive to the cleaning effect. The nozzle needs to be moved manually regularly. However, the nozzle of this device is sent to a high position together with the collection cover during use and cannot be adjusted manually. Therefore, a nozzle swing module is designed to realize the circular motion of the nozzle within a certain range of the horizontal plane to improve the spraying effect.

[0037] The nozzle oscillating device of the present invention is powered by an electric motor. The motor speed is reduced by an internal speed reducer, which drives the gear set to rotate, thereby rotating the disc, causing the rack to move back and forth, thereby causing the nozzle to oscillate. The present invention can precisely control the range of the nozzle's circular reciprocating motion, and has better applicability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0046] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments and features of the embodiments may be combined unless they conflict. For ease of description, the words "upper," "lower," "left," and "right" appear below merely to indicate the directions of upper, lower, left, and right in the accompanying drawings and do not limit the structure.

[0047] like Figure 1 、 Figure 2 As shown, the present embodiment provides an air cooler flushing device for a converter station, which includes a chassis device 100 , a lifting device 200 and a cleaning device 300 .

[0048] like Figure 1 、 Figure 3 As shown, the chassis device 100 includes a trolley chassis 15, casters 16 provided at the bottom of the trolley chassis 15, and a trolley handle 4 connected to one end of the moving direction of the trolley chassis 15. By pushing the trolley handle 4, the chassis device 100 can be moved to a place that needs to be cleaned.

[0049] like Figure 1-Figure 3 As shown, the lifting device 200 includes a limit screw 1, a lifting support plate 5, a telescopic bracket 11, a synchronization rod 12, a pulley 13, a lifting ring 19, a switch 20, a battery 21, an electric winch 23, a controller 22, a base frame 24, a bearing 25 and a traction rope 29.

[0050] The base frame 24 is mounted on the chassis device 100, the lifting support plate 5 is located above the base frame 24, and the telescopic bracket 11 is connected between the base frame 24 and the lifting support plate 5. The telescopic bracket 11 is arranged in two groups at intervals perpendicular to the travel direction of the chassis device 100. The two groups of telescopic brackets 11 are connected by a synchronization rod 12, and the synchronization rod 12 is located at the corner of all telescopic brackets 11. A synchronization rod 12 located at the lower end of the telescopic bracket 11 is fixedly hinged to the base frame 24, and another synchronization rod 12 located at the lower end of the telescopic bracket 11 is slidably connected to the base frame 24. The pulley 13 is provided on the fixedly hinged synchronization rod 12, and the sliding synchronization rod 12 is provided with a lifting ring 19. One end of the traction rope 29 is connected to the lifting ring 19 (as shown in FIG. Figure 6 As shown), one end of the traction rope 29 away from the synchronization rod 12 is connected to the electric winch 23 after being wound around the pulley 13. The electric winch 23, the battery 21 and the controller 22 are arranged on the trolley chassis 15.

[0051] like Figure 2 、 Figure 4 As shown, the electric winch 23, the battery 21, the controller 22 and the switch 20 are electrically connected. The switch 20 is set on the handle 4 of the trolley for easy operation. When the switch 20 is turned on, the lifting device 200 can be operated to rise and fall.

[0052] like Figure 6 As shown, a slide groove is provided on the inner side of the base frame 24, and bearings 25 adapted to the slide groove are provided at both ends of the slidingly connected synchronization rod 12 to reduce friction resistance.

[0053] like Figure 3 As shown, the base frame 24 is provided with a limit screw 1 for limiting the displacement of the sliding synchronization rod 12. The limit screw 1 is used to limit the maximum height of the lifting device 200 to prevent the flushing device from colliding with the bottom of the air-cooling island fin tube due to worker misoperation.

[0054] The electric winch 23 retracts the traction rope 29 and drives the sliding synchronization rod 12 to move, realizing the lifting function of the shear-type lifting device 200. When the electric winch 23 slowly releases the traction rope 29, the lifting device 200 descends by itself under the action of gravity, realizing the descending function of the shear-type lifting device 200.

[0055] like Figure 1 、 Figure 2 As shown, the cleaning device 300 includes a drainage hose 2, a pump 3, a drainage hard pipe 6, a collection cover 7, a nozzle 8, a fixing rod 9, a base 10, a return hose 14, a plug 17, a water tank 18, a filter 26, a nozzle swing device 30 and a nozzle 28.

[0056] like Figure 4As shown, the water tank 18 and the pump 3 are placed on the trolley chassis 15. The water tank 18 is provided with a liquid level alarm device 31. When the liquid level inside the water tank 18 is lower than the set value, the buzzer sounds to remind the worker to add detergent to the water tank.

[0057] like Figure 5 、 Figure 7 As shown, the base 10 is arranged on the lifting support plate 5, and the base 10 is arranged along the periphery of the collecting hood 7. A fixing rod 9 is vertically inserted into the base 10. A nozzle swing device 30 is provided on each of the fixing rods 9. The nozzle swing device 30 includes a mounting frame 27 connected to the edge of the collecting hood 7 and a motor 301, a disc 302, a rack 303, a pinion 304, a U-shaped block 305 and a gear set 306 installed on the mounting frame 27. The power output end of the motor 301 is connected to the power input end of the gear set 306, and the power output end of the gear set 306 is connected to the disc 302. The gear set 306 is provided with at least two gears, one forming an input end connected to the motor shaft of the motor 301, and one forming an output end, which is coaxially connected to the disc 302.

[0058] A lever 307 is provided on the upper surface of the disk 302. The mounting frame 27 is also provided with at least two slide frames 309, into which the ends of the rack 303 slide. The rack 303 is provided with a shifting slot 308, into which the lever 307 fits. The pinion 304 meshes with the rack 303 and is connected to the U-shaped block 305. The nozzle 8 is mounted in the U-shaped block 305, with the nozzle 8 facing upward. The mounting frame 27 is provided with a mounting hole 310, through which the fixing rod 9 extends.

[0059] When in use, the motor 301 is started, and the driving force input value of the motor 301 is output through the gear set 306, driving the disc 302 to rotate. The lever 307 on the disc 302 drives the rack 303 to move back and forth along the slide frame 309, thereby driving the pinion 304 and the U-shaped block 305 thereon to reciprocate in a certain range in the horizontal plane, thereby realizing the swing of the nozzle 8 to expand the spraying range.

[0060] Reference formula for the design of the reciprocating swing angle of the pinion 304 (1)

[0061] θ=2r0 / r1(1)

[0062] Where, θ: the angular range of the reciprocating swing of the pinion 304, rad

[0063] r0: The distance between the center of the cylindrical rod on the special disc and the center of the special disc, mm

[0064] r1: Pitch circle radius of pinion 304, mm.

[0065] By controlling the size of r0 and r1, the range of the nozzle's circular reciprocating motion can be precisely controlled.

[0066] Mounting frame 27. The mounting frame 27 is fixed to the upper edge of the collection cover 7, and the collection cover 7 is supported above the lifting support plate 5.

[0067] like Figure 1 、 Figure 2 、 Figure 5 As shown, the drainage hard pipe 6 is arranged on the lifting support plate 5. One end of the drainage hose 2 is connected to the water tank 18, and the pump 3 is connected to the drainage hose 2 of this section. The other end of the drainage hose 2 is connected to the drainage hard pipe 6. A nozzle 28 is arranged next to each fixed rod 9. The lower ends of multiple nozzles 28 are connected to the drainage hard pipe 6. A nozzle 8 is provided at the upper end of each nozzle 28. A water outlet is provided at the bottom of the collecting cover 7, and a filter 26 is provided at the water outlet. The water outlet is connected to the water tank 18 through the return hose 14. The drainage hose 2 and the return hose 14 are extended and retracted as the lifting device 200 is lifted and lowered. The water tank 18 is placed on the trolley chassis 15

[0068] like Figure 1 As shown, a plug 17 is movably provided on the side wall of the water tank 18, and the plug 17 is provided near the lower end of the water tank 18. The plug 17 is used to block the cleaning liquid to prevent leakage; after cleaning, the plug 17 can be opened to drain the cleaning liquid, which is convenient for replacement and disposal of the cleaning liquid. The upper end of the water tank 18 is provided with an opening to facilitate timely replenishment of cleaning liquid lost during operation. The upper end opening of the collection cover 7 is larger than the water outlet at the bottom, and on the same top projection plane, the upper end opening of the collection cover 7 is eccentric to the water outlet, thereby forming a special-shaped structure.

[0069] The water tank 18 stores cleaning fluid. During operation, the cleaning fluid is sprayed from the nozzles 8 onto the contaminated area at the bottom of the air-cooling island's finned tubes. Gravity then causes most of the cleaning fluid to fall into the collection hood 7, where it is filtered by the filter 26 and returned to the water tank 18 via the return hose 14, thus fulfilling both the cleaning and cleaning fluid collection functions of the device. The placement of the nozzles 8 on the edge of the collection hood 7 can be adjusted based on practical needs, including the number and distribution of the nozzles 8 along the upper arc of the collection hood 7, as well as their elevation angle.

[0070] In this device, the water tank 18, battery 21, pump 3, and electric winch 23 are located at the bottom, effectively lowering the center of gravity of the chassis 100 and improving the stability of the flushing device during operation. The casters 16 are industrial casters with a self-locking function, which can be used to position the flushing device at a selected position, preventing the flushing device from slipping during operation due to environmental and human factors, which could affect the cleaning effect and cause safety issues.

[0071] The stains on the bottom of the air cooler's finned tubes are mainly distributed in the middle of the finned tube grid. Therefore, when using this device, workers can push it to the stained area, lock the wheels, and then start cleaning. After cleaning, release the self-locking function and push the cart to the next area to repeat the process. During the operation of this device, workers only need to push the cart to the designated location at intervals, which greatly reduces the workers' workload. At the same time, the close-range multi-nozzle cleaning also greatly improves the flushing effect, and the use of special-shaped collection hoods increases the recycling rate of water resources. When the device is idle, the lift can be lowered to the lowest level, making the device compact and convenient, and can be moved in the densely populated space under the finned tubes of the air-cooling island.

[0072] The present invention improves the existing method for cleaning the bottom of the air-cooling island fin tube, increases the utilization rate of the cleaning liquid, relieves the work intensity of workers, and ensures the reliability, safety and stability of the device.

[0073] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
