Description

Technical Field

[0001] This invention relates to the field of indirect cooling tower technology, and in particular to a flushing device for indirect cooling towers. Background Technology

[0002] As a key component of industrial circulating water cooling systems, indirect cooling towers operate under long-term exposure to the natural environment. The surface of the indirect cooling tower fans easily absorbs dust, particulate matter, and other pollutants from the air, gradually forming a layer of fouling. This fouling reduces the heat exchange efficiency of the indirect cooling tower fans, hinders heat exchange between the circulating cooling water and the air, and consequently affects the overall operating efficiency of the cooling system, leading to increased energy consumption and potentially causing safety hazards such as equipment overheating.

[0003] Currently, the dust adhering to the surface of the indirect cooling tower fan is cleaned by periodic rinsing. However, the existing rinsing equipment is interfered with by the cold water pipes of the indirect cooling tower during vertical movement. This causes the rinsing equipment to retract the rinsing components that extend into the fan area to be cleaned when passing through the cold water pipe area in order to avoid the cold water pipes. After passing the cold water pipes, it extends again to work, resulting in a discontinuous cleaning process, low cleaning efficiency, and blind spots in the cleaning process, which affects the overall cleaning effect.

In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0055] like Figure 1 As shown, an embodiment of the present invention provides a flushing device for an intercooling tower, wherein the intercooling tower 1 includes a plurality of sector surfaces to be cleaned arranged sequentially along the circumferential direction and a cold water pipe 2 protruding from the sector surfaces to be cleaned. In the vertical direction, the sector surfaces to be cleaned include a first sector surface 11 located above the cold water pipe 2 and a second sector surface 12 located below the cold water pipe 2. The rinsing equipment includes a first running track 100 located at the bottom of the intercooling tower 1, a second running track 200 located at the top of the intercooling tower 1, and a rinsing ladder 300 located between the first running track 100 and the second running track 200. The bottom of the rinsing ladder 300 is provided with a first drive assembly 400 that is rollably connected to the first running track 100, and the top of the rinsing ladder 300 is provided with a second drive assembly 500 that is rollably connected to the second running track 200. Two sets of cleaning assemblies are provided on the rinsing ladder 300. The cleaning assemblies include rinsing assemblies 600 that move along the axis of the rinsing ladder 300, and the rinsing assemblies 600 of the two sets of cleaning assemblies rinse the first sector surface 11 to be cleaned and the second sector surface 12 to be cleaned, respectively. During operation, the first drive assembly 400 and the second drive assembly 500 synchronously drive the flushing ladder 300 to move horizontally along the first running track 100 and the second running track 200, causing the flushing ladder 300 to move around the circumference of the cooling tower 1. This allows the flushing components 600 of the two sets of cleaning components to continuously flush the first sector surface 11 and the second sector surface 12 to be cleaned, respectively. Simultaneously, the flushing components 600 reciprocate along the axis of the flushing ladder 300, ensuring thorough cleaning coverage and improving cleaning quality. Through coordinated structural design, synchronous cleaning of the upper and lower sectors is achieved, significantly improving cleaning efficiency, reducing manual maintenance costs, and enhancing operational safety.

[0056] like Figure 2 As shown, a limit block 310 is fixed on the flushing ladder 300. In the axial direction of the flushing ladder 300, the limit block 310 is located between the flushing components 600 of the two sets of cleaning components. The limit block 310 is used to limit the range of motion of the two sets of flushing components 600, prevent them from interfering with each other during reciprocating motion, and ensure operational stability.

[0057] like Figure 2 and Figure 3 As shown, the rinsing assembly 600 includes a cleaning frame 610, a cleaning pipe 620 fixed on the cleaning frame 610, and a lifting trolley 630 that is rotatably connected to the rinsing ladder 300; the lifting trolley 630 is provided with a rotatable rotating shaft 631, and the cleaning frame 610 is fixedly connected to the rotating shaft 631 and can rotate around the rotating shaft 631.

[0058] A rotary drive assembly 640 is installed on the lifting trolley 630. The rotary drive assembly 640 includes an electric cylinder 641 and a linkage shaft 642. The electric cylinder 641 is fixed on the lifting trolley 630 and located above the rotary shaft 631. One end of the linkage shaft 642 is hinged to the telescopic rod 6410 of the electric cylinder 641, and the other end is fixedly sleeved in the middle of the rotary shaft 631. When the telescopic rod 6410 of the electric cylinder 641 extends or retracts, it drives the rotary shaft 631 to rotate through the linkage shaft 642, thereby driving the cleaning rack 610 to rotate around the rotary shaft 631. When the telescopic rod 6410 of the electric cylinder 641 extends, the linkage shaft 642 drives the rotating shaft 631 to rotate, causing the cleaning frame 610 to unfold outward, and the cleaning pipe 620 to rotate to the working angle to perform rinsing operations on the outer wall of the indirect cooling tower; when the telescopic rod 6410 retracts, the linkage shaft 642 drives the rotating shaft 631 to rotate in the opposite direction, causing the cleaning frame 610 to retract inward, and the cleaning pipe 620 to rotate to the non-working angle to avoid interference with the outer wall of the indirect cooling tower. At this time, the rinsing ladder 300 drives the lifting trolley 630 to run along the track to the next working position.

[0059] like Figure 4As shown, the cleaning assembly also includes a lifting drive assembly 700, which includes a roller shaft 710, a winding roller 720, a seated bearing 730, a first motor 740, a fixed pulley 770, and a wire rope 780. The winding roller 720 is fixedly sleeved on the roller shaft 710, and the seated bearing 730 is fixed on the flushing ladder 300. A pair of seated bearings 730 are respectively located at both ends of the winding roller 720 in the axial direction; and both ends of the roller shaft 710 are respectively fixed to a pair of seated bearings 730. The first motor 740 is connected to a first reducer 750, whose output shaft is coaxially and fixedly connected to a drum shaft 710 via a first coupling 760. Multiple fixed pulleys 770 are fixed to the top of the washing ladder 300. A wire rope 780 is wound around a winding drum 720, with one end of the wire rope 780 passing through multiple fixed pulleys 770 and then fixedly connected to a lifting trolley 630. The top of the lifting trolley 630 has a rope-passing hole 632 for the wire rope 780 to pass through. When the first motor 740 starts, power is transmitted to the drum shaft 710 via the first reducer 750 and the first coupling 760, causing the winding drum 720 to rotate, thereby winding and unwinding the wire rope 780. After the wire rope 780 changes direction via the fixed pulleys 770, it pulls the lifting trolley 630 vertically up and down along the washing ladder 300. During the lifting process, the rope hole 632 ensures that the wire rope 780 passes through smoothly without deviation, thus achieving stable operation of the lifting trolley 630.

[0060] like Figure 5 and Figure 6As shown, the first running track 100 is an I-beam; the first drive assembly 400 includes a lower support frame 410 and a first drive module 420. The bottom of the washing ladder 300 is fixed to the middle position of the lower support frame 410. A pair of first drive modules 420 are arranged on the lower support frame 410 and are respectively located at the radial ends of the washing ladder 300; the first drive module 420 includes a lower drive shaft 421, a lower traveling wheel 422, a second motor 423, a second reducer 424, and a second coupling 425. The lower drive shaft 421 is rotatably mounted on the lower support frame 410. The lower drive shaft 421 is located directly above the first running track 100 on the support frame 410. The lower traveling wheel 422 is fixedly sleeved on the lower drive shaft 421 and connected to the upper surface rollers on the first running track 100. The second reducer 424 is connected to the output end of the second motor 423, and the output shaft of the second reducer 424 is coaxially and fixedly connected to the lower drive shaft 421 via a second coupling 425. A mounting plate 411 is fixed above the lower support frame 410, and the second reducer 424 is fixedly connected to the mounting plate 411. When the second motor 423 starts, power is transmitted to the lower drive shaft 421 via the second reducer 424 and the second coupling 425, causing the lower traveling wheel 422 to roll on the first running track 100, thereby driving the entire flushing ladder 300 to move horizontally along the I-beam track. The mounting plate 411 ensures the stable fixation of the second reducer 424, preventing vibration and displacement during operation and ensuring smooth operation of the transmission system. The synchronous operation of the pair of first drive modules 420 ensures that the lower support frame 410 is subjected to balanced forces, thereby improving the stability and safety of the equipment operation.

[0061] The first drive assembly 400 also includes a first guide wheel assembly 430, with a pair of first guide wheel assemblies 430 respectively fixed at both ends of the lower support frame 410. Each first guide wheel assembly 430 includes a first mounting bracket 431 fixed to the lower support frame 410, on which a pair of first guide wheels 432 are mounted. The pair of first guide wheels 432 are tactilely connected to opposite sides of the first running track 100. The first guide wheels 432 fit tightly against the side wings of the I-beam, effectively limiting the lateral displacement of the flushing ladder 300 during horizontal movement and enhancing operational guidance accuracy.

[0062] like Figure 7 and Figure 8As shown, the second running track 200 is made of channel steel; the second drive assembly 500 includes an upper support plate 510 and a second drive module 520. The top of the flushing ladder 300 is fixedly connected to the upper support plate 510. A pair of second drive modules 520 are disposed on the upper support plate 510 and located at the radial ends of the second running track 200, respectively. The second drive module 520 includes a third motor 521, an upper drive shaft 522, a third coupling 523, and an upper traveling wheel 524. The upper traveling wheel 524 is fixedly sleeved on the upper drive shaft 522 and is rolletically connected to the second running track 200. The output shaft of the third motor 521 is coaxially fixedly connected to the upper drive shaft 522 through the third coupling 523. After the third motor 521 is started, the power is transmitted to the upper drive shaft 522 through the third coupling 523, driving the upper traveling wheel 524 to roll on the side surface of the channel steel track, thus driving the flushing ladder 300 to move smoothly along the second running track 200.

[0063] The second drive assembly 500 further includes a plurality of second guide wheel assemblies 530 and a third guide wheel assembly 540; the second running track 200 has a guide rail groove 210, and the plurality of second guide wheel assemblies 530 are rolledly engaged with the side of the second running track 200 away from the guide rail groove 210; the plurality of third guide wheel assemblies 540 are rolledly engaged with the side of the second running track 200 near the guide rail groove 210; the second guide wheel assembly 530 includes a second mounting bracket 531 fixed on the upper support plate 510, and a second guide wheel 532 is provided on the second mounting bracket 531; the third guide wheel assembly 540 includes a third mounting bracket 541 fixed on the upper support plate 510, and a third guide wheel 542 is provided on the third mounting bracket 541, and the thickness of the third guide wheel 542 is greater than the thickness of the second guide wheel 532.

[0064] like Figure 9 As shown, the rinsing equipment also includes a ring track device for storing and moving hoses and cables required for the rinsing equipment. The ring track device includes a cable chain 800 and a trough 900. The cable chain 800 can be folded to form a first cable chain section 810, a second cable chain section 820, and a bent cable chain section 830 connected between the first cable chain section 810 and the second cable chain section 820. The first cable chain section 810, the second cable chain section 820, and the bent cable chain section 830 are arranged horizontally. The trough 900 is annular and is used to store the cable chain 800. The trough 900 has a concentric outer annular groove 910 and an inner annular groove 920 inside. The first cable chain section 810 is accommodated in the outer annular groove 910, and the second cable chain section 820 is accommodated in the inner annular groove 920. By horizontally arranging the entire cable chain 800 within the trough 900, space is effectively utilized and the swaying amplitude of the cable chain during equipment operation is reduced, improving the guiding stability of the hose and cable. This effectively prevents the cable chain 800 from detaching from the trough 900 due to excessive swaying, thereby ensuring the safety and reliability of the flushing equipment during long-term operation.

[0065] like Figure 10 As shown, the bottom of each outer annular groove 910 is provided with multiple first rollers 911, which are used to support the first cable chain section 810; the bottom of each inner annular groove 920 is provided with multiple second rollers 921, which are used to support the second cable chain section 820. The first rollers 911 and the second rollers 921 are evenly distributed along the extension direction of their respective annular grooves, which greatly reduces the friction between the cable chain 800 and the bottom of the tank 900 when it reciprocates with the flushing ladder 300.

[0066] like Figure 11 As shown, the slot box 900 includes an outer perimeter wall 940, an inner perimeter wall 950, and a bottom wall 960 connected between the outer perimeter wall 940 and the inner perimeter wall 950, which are disposed opposite to each other; an outer ring wall 970 and an inner ring wall 980 are also fixed on the bottom wall 960; an outer annular groove 910 is formed between the outer ring wall 970, the outer perimeter wall 940 and the bottom wall 960, and a first roller 911 is rotatably connected between the outer perimeter wall 940 and the outer ring wall 970; an inner annular groove 920 is formed between the inner ring wall 980, the inner perimeter wall 950 and the bottom wall 960, and a second roller 921 is rotatably connected between the inner perimeter wall 950 and the inner ring wall 980.

[0067] Multiple openings 961 are provided on the bottom wall 960, and the multiple openings 961 are arranged at intervals along the extension direction of the slot box 900. The openings 961 are used to reduce the overall weight of the slot box 900 and reduce costs.

[0068] The bent cable chain section 830 smoothly transitions between the inner and outer annular grooves as the equipment moves, reducing movement resistance and extending the cable chain's service life. Therefore, the annular track device also includes an outer ring transition bar 971 and an inner ring transition bar 972. The outer ring transition bar 971 is annular and positioned close to the outer annular groove 910, while the inner ring transition bar 972 is annular and positioned close to the inner annular groove 920. The outer surfaces of the outer ring transition bar 971 and the inner ring transition bar 972 are arc-shaped and respectively support the opposite ends of the bent cable chain section 830. The outer ring transition bar 971 and the inner ring transition bar 972 ensure that the bent cable chain section 830 smoothly slides from the outer annular groove 910 into the inner annular groove 920 or vice versa, avoiding wear and jamming caused by uneven friction or concentrated force, significantly improving movement stability and structural durability.

[0069] Both the outer ring transition strip 971 and the inner ring transition strip 972 are cylindrical, with the outer ring transition strip 971 fixed directly above the outer ring wall 970 and the inner ring transition strip 972 fixed directly above the inner ring wall 980. Horizontally, the highest point of the outer ring transition strip 971 is lower than the highest point of the outer ring wall 940, and the highest point of the inner ring transition strip 972 is lower than the highest point of the inner ring wall 950. This ensures that the bending cable chain section 830 does not interfere with the outer ring wall 970 or the inner ring wall 980 during the transition process.

[0070] like Figures 12-14 As shown, the cable chain 800 includes multiple links 840 connected in sequence. Each link 840 includes a support assembly 850 and a pair of connecting plates 860 symmetrically arranged at both ends of the support assembly 850. The connecting plates 860 are Z-shaped structural plates, with circular bosses 862 and circular grooves 861 on their respective ends. The circular bosses 862 of the links 840 rotatably engage with the circular grooves 861 of the adjacent links 840. This enables flexible hinged connections between adjacent links 840, giving the cable chain good bending performance and freedom of movement, thus adapting to the reciprocating motion requirements under complex paths.

[0071] The outer periphery of the circular groove 861 is further surrounded by multiple fan-shaped grooves 863. The connecting plate 860 is also equipped with multiple sliding blocks 864 corresponding one-to-one with the fan-shaped grooves 863, and the sliding blocks 864 are slidably connected within the fan-shaped grooves 863. The sliding blocks 864 can slide synchronously within the fan-shaped grooves 863 as the bending angle of the chain link 840 changes, effectively limiting excessive torsion and enhancing structural stability. The contact surface between the sliding blocks 864 and the fan-shaped grooves 863 is arc-shaped, reducing wear and improving durability. When the cable chain 800 reciprocates along the circular track, the sliding blocks 864 slide along the trajectory of the fan-shaped grooves 863, assisting in adjusting the rotation angle between adjacent chain links 840, preventing jamming or stress concentration, and further ensuring the smoothness and reliability of the cable chain operation.

[0072] The outer side of the connecting plate 860 is provided with a plurality of contact protrusions 865 spaced apart from each other. The contact protrusions 865 are slidably connected to the bottom of the slot box 900, and the frictional resistance is reduced by point contact during the movement.

[0073] The contact boss 865 is elongated, and its axial direction is aligned with that of the cable chain 800. This ensures stable sliding guidance during reciprocating motion, effectively disperses local pressure, and prevents friction buildup and increased wear caused by excessive contact area.

[0074] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
