Description

Technical Field

[0001] The present application relates to the technical field of cleaning power equipment, and in particular to a cleaning device for the surface of an air cooler tube bundle. Background Art

[0002] Air-cooled island (air cooler) is the abbreviation of air-cooled heat exchanger. It is a large-scale industrial heat exchange equipment that uses natural air to cool (condense) fluids. Compared with water cooling, it has the characteristics of sufficient cooling source, saving cooling water, reducing environmental pollution and low maintenance costs. Thermal power generation requires cooling of turbine exhaust steam. Traditional water cooling requires a large amount of fresh water. Air-cooled units can achieve zero water discharge; simply put, the principle is the same as that of the cooling tower of a power plant, which is used to dissipate heat. However, steam (hot water) in the air-cooled island mainly relies on the internal fan to dissipate heat. Water does not evaporate during the heat dissipation process. Therefore, the air-cooled heat dissipation method saves water more than the cooling tower heat dissipation method. Therefore, air-cooled units are mainly widely distributed in the northern region of my country.

[0003] The air cooling system is mainly composed of air-cooled condenser tube bundles, axial flow fans and other components. A large number of heat dissipation fins are arranged on the surface of the air-cooled condenser tube bundle to increase the heat dissipation effect. Since the tube bundles in the air-cooled condenser are arranged outdoors for a long time, and the wind is strong and dusty in the northern region, the fine sand, dust in the air, and other impurities carried by the strong wind are easily accumulated on the fins of the tube bundle, which will hinder the heat exchange of the air-cooled island condenser, resulting in a decrease in the efficiency of its cold and heat exchange. In severe cases, it will even directly affect the back pressure of the unit, causing the unit power generation coal value to increase. Therefore, it is necessary to clean the heat dissipation fins with high-pressure water to ensure the cleanliness of the heat dissipation fins of the tube bundle and improve the heat exchange effect of the air-cooled condenser.

[0004] However, at present, when cleaning the air cooling island, workers usually climb up the horizontally movable ladder outside the tube bundle with high-pressure water guns, and wash the inclined tube bundle surface from top to bottom. Because the vertical height of the tube bundle is relatively high, there is a risk of high-altitude operation when workers hold high-pressure water guns to clean the high areas on the tube bundle surface.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.

[0026] like Figure 1 and Figure 2 As shown, a cleaning device for the surface of an air cooler tube bundle disclosed in the present application comprises a tube bundle 1 and a ladder 2 located at one side of the tube bundle 1, and a high-position dirt cleaning mechanism 3 is provided on the ladder 2 near the side of the tube bundle 1; the high-position dirt cleaning mechanism 3 comprises a first slide rail 31, a second slide rail 32 and a third slide rail 33 located between the ladder 2 and the tube bundle 1, and they are arranged in sequence along a direction perpendicular to the surface of the tube bundle 1, the first slide rail 31 is fixedly mounted on the ladder 2; the second slide rail 32 is movably connected to the first slide rail 31, and the third slide rail 33 is movably connected to the first slide rail 31. 3 is movably connected with the second slide rail 32; a nozzle 34 is provided on the top of the third slide rail 33, and the nozzle 34 is connected with a water pipe 35, and the water pipe 35 can provide high-pressure water to the nozzle 34; a driving unit 4 is provided on the side of the ladder 2 away from the tube bundle 1, and the first slide rail 31, the second slide rail 32 and the third slide rail 33 are all connected with the driving unit 4, and the driving unit 4 can change the relative positions of the first slide rail 31, the second slide rail 32 and the third slide rail 33, so that the nozzle 34 on the third slide rail 33 can wash the high area on the surface of the tube bundle 1.

[0027] In the above embodiments, the upper and lower ends of the ladder 2 of the present application are respectively slidably clamped on the guide rails at the corresponding positions, and the ladder 2 can move freely along the length direction of the tube bundle 1 through the guide rails. The existing ladder 2 and its related moving mechanism are prior art and will not be described in detail here. The climbing area on the ladder 2 of the present application is close to one side of its width direction, so that the other side of the ladder 2 in the width direction has a certain vacant area, which can be used to install the high-position dirt cleaning mechanism 3. When workers need to inspect and repair the surface of the tube bundle 1 through the ladder 2, the high-position return cleaning mechanism will not affect the workers.

[0028] The first slide rail 31, the second slide rail 32 and the third slide rail 33 of the present application all have openings and their openings all face the tube bundle 1. The closed end of the first slide rail 31 is fixedly connected to the ladder 2, the closed end of the second slide rail 32 is inserted into the open end of the first slide rail 31 and the two are slidably connected along the tilting direction of the ladder 2, and the closed end of the third slide rail 33 is inserted into the open end of the second slide rail 32 and the two are slidably connected along the tilting direction of the ladder 2. In this way, when the driving unit 4 drives the second slide rail 32 and the third slide rail 33 to be unfolded at the same time, the nozzle 34 on the third slide rail 33 can be moved to the highest point of the tube bundle 1. A stopper may be provided at the top of the first slide rail 31 to prevent the second slide rail 32 from being separated from the first slide rail 31 when it moves. Similarly, a stopper may be provided at the top of the second slide rail 32 to prevent the third slide rail 33 from being separated from the second slide rail 32. In addition, the heights of the first slide rail 31, the second slide rail 32 and the third slide rail 33 of the present application are not higher than the body height of a normal worker. Therefore, when the nozzle 34 moves from the highest point of the tube bundle 1 to the position where the third slide rail 33 and the second slide rail 32 are both retracted into the first slide rail 31, the surface area of ​​the tube bundle 1 that the worker standing on the steel structure platform cannot reach can be automatically cleaned. In this way, the worker does not need to climb the ladder 2 to clean the unreachable area on the surface of the tube bundle 1, thereby effectively reducing the risk of high-altitude work when the worker cleans the surface of the tube bundle 1 at a high place on the ladder 2.

[0029] Furthermore, if Figure 1 , Figure 3 and Figure 4 As shown, the driving unit 4 includes three fixed rods 41, two fixed pulleys 42, a first traction rope 43, a second traction rope 44 and a winding assembly 45. The three fixed rods 41 are respectively fixed on the same side of the lower ends of the first slide rail 31, the second slide rail 32 and the third slide rail 33, and the two fixed pulleys 42 are respectively fixed on the same side of the upper ends of the first slide rail 31 and the second slide rail 32; one end of the first traction rope 43 is connected to the winding assembly 45, and the other end of the first traction rope 43 passes over the fixed pulley 42 on the second slide rail 32 from above and is fixedly connected to the fixed rod 41 on the second slide rail 32 downward, and the winding assembly 45 can freely control the retraction and release of the first traction rope 43; one end of the second traction rope 44 is fixedly connected to the fixed rod 41 on the first slide rail 31, and the other end of the second traction rope 44 passes over the fixed pulley 42 on the second slide rail 32 upward and is fixedly connected to the fixed rod 41 on the third slide rail 33 downward.

[0030] In the above embodiments, the air cooler tube bundle 1 is installed on an A-shaped bracket, so the surface of the tube bundle 1 is inclined. If it is cleaned from bottom to top, the dirty water generated when cleaning the upper area will pollute the cleaned area below, so the lower area of ​​the tube bundle 1 surface needs to be cleaned repeatedly, which increases water consumption and reduces cleaning efficiency. Therefore, general workers use high-pressure water to clean the surface of the tube bundle 1 from top to bottom, that is, first clean the high part of the surface of the tube bundle 1, and then clean the low part of the surface of the tube bundle 1. Taking the cleaning device of the present application as an example, in the top-down cleaning method, the process of the nozzle 34 moving from bottom to top does not require water spraying for cleaning work, so increasing its upward movement speed can effectively improve the cleaning efficiency of the surface of the tube bundle 1.

[0031] The first slide rail 31, the second slide rail 32 and the third slide rail 33 of the present application are arranged in the above manner with the driving unit 4, so that when the winding assembly 45 performs the winding operation on the first traction rope 43, the first traction rope 43 can carry the second slide rail 32 along the first slide rail 31 through the connection point between the first traction rope 43 and the fixed rod 41 on the second slide rail 32 and unfold upward. When the second slide rail 32 unfolds, the position of the fixed pulley 42 thereon will also change accordingly, and the positions of the first slide rail 31 and the fixed rod 41 thereon are fixed, so the fixed pulley 42 on the second slide rail 32 When the position of the third slide rail 33 changes, in order to adapt to the increase in the distance between the fixed rod 41 on the first slide rail 31 and the fixed pulley 42 on the second slide rail 32, the distance between the fixed pulley 42 on the second slide rail 32 and the fixed rod 41 on the third slide rail 33 will be reduced accordingly. In this way, the third slide rail 33 will be synchronously driven by the second traction rope 44 to unfold upward along the second slide rail 32. When the basic position of the third slide rail 33 on the second slide rail 32 changes, the position of the nozzle 34 thereon will also change accordingly. During this process, the winding assembly 45 is set up to wind up the first traction rope 43 with a length of A. At this time, the second slide rail 32 will move upward along the first slide rail 31 for a corresponding distance B. During the movement of the second slide rail 32, the second traction rope 44 will drive the third slide rail 33 to move upward along the second slide rail 32 for a corresponding distance C. It can be seen that the winding assembly 45 winds up the first traction rope 43 with a length of A, and can drive the third slide rail 33 to move upward a distance B+C on the basis of the initial position, wherein the lengths of A, B, and C are similar. In this way, the moving distance of the nozzle 34 in the present application will be much greater than the length of the winding segment of the winding assembly 45, thereby effectively improving the moving speed of the nozzle 34 when moving from bottom to top on the surface of the tube bundle 1, and improving the cleaning efficiency of the surface of the tube bundle 1.

[0032] When it is necessary to move the nozzle 34 downward from the highest point on the surface of the tube bundle 1, the first traction rope 43 is released again from the winding assembly 45, and the second slide rail 32 and the third slide rail 33 are automatically reset under the action of gravity and move the nozzle 34 downward. In actual production, in order to ensure that the reset process of the second slide rail 32 and the third slide rail 33 is smoother, a counterweight block can be added to the third slide rail 33 to improve its gravity driving effect, and rollers can be added at the connection between the first slide rail 31 and the second slide rail 32 and at the connection between the second slide rail 32 and the third slide rail 33, so as to reduce friction when the second slide rail 32 and the third slide rail 33 are reset.

[0033] like Figure 5 As shown, in addition, the planes where the first traction rope 43 and the second traction rope 44 of the present application are located are not coplanar, so that the first traction rope 43 and the second traction rope 44 can avoid mutual obstruction during the movement of the second slide rail 32 and the first slide rail 31.

[0034] Furthermore, if Figure 1 , Figure 3 and Figure 4 As shown, the winding assembly 45 includes a winding motor 451, which is fixedly mounted on the side wall of the ladder 2 away from the tube bundle 1 through a motor bracket 452, the output end of the winding motor 451 is fixedly connected to the take-up wheel 453, one end of the first traction rope 43 is fixedly connected to the take-up wheel 453, and part of the first traction rope 43 is wound around the take-up wheel 453; an avoidance hole 454 is provided at a position on the ladder 2 corresponding to the first traction rope 43, and the avoidance hole 454 allows the first traction rope 43 to pass through the ladder 2 smoothly when moving.

[0035] In the above embodiment, when the winding motor 451 is started and rotates clockwise, the winding process of the first traction rope 43 can be completed through the winding wheel 453, so that the second slide rail 32 and the third slide rail 33 are unfolded, that is, the effect of the nozzle 34 moving from low to high on the surface of the tube bundle 1; when the winding motor 451 rotates counterclockwise, the wound first traction rope 43 can be released, so that the second slide rail 32 and the first slide rail 31 can be reset, that is, the effect of the nozzle 34 moving from high to low on the surface of the tube bundle 1. Workers on the steel structure platform only need to control the rotation direction of the winding motor 451 to control the moving direction of the nozzle 34, which is very convenient to operate.

[0036] Furthermore, if Figure 2 As shown, the third slide rail 33 is fixedly connected to the baffle 5 on the side close to the tube bundle 1, the nozzle 34 is installed on the upper end of the baffle 5, the water pipe 35 is laid in the third slide rail 33 and is located on the side of the baffle 5 away from the tube bundle 1, one end of the water pipe 35 is connected to the nozzle 34, and the other end of the water pipe 35 is connected to the water supply pipeline.

[0037] In the above embodiment, the baffle 5 on the third slide rail 33 can cooperate with the third slide rail 33 body to form a channel inside the third slide rail 33, and a partial section of the water pipe 35 can be installed in the channel of the third slide rail 33 through a pipe clamp, so that the third slide rail 33 can disperse the force acting on the water pipe 35 to multiple connection points between it and the water pipe 35 when moving, ensuring that the water pipe 35 can move smoothly with the third slide rail 33 when the third slide rail 33 moves, and can effectively reduce the force on the connection between the nozzle 34 and the water pipe 35, preventing the water pipe 35 from falling off from the connection with the nozzle 34 during the movement of the third slide rail 33.

[0038] Furthermore, if Figure 1 and Figure 4 As shown, a guide block 6 is installed above the side wall of the third slide rail 33 on which a fixing rod 41 is provided, and a guide groove 7 is provided on the side wall of the ladder 2 on the same side as the guide block 6. The end of the guide block 6 away from the third slide rail 33 is inserted into the guide groove 7 and the two are slidably connected.

[0039] In the above embodiment, the guide block 6 on the third slide rail 33 is inserted into the guide groove 7 on the corresponding side of the ladder 2, and the inclination direction of the guide groove 7 is the same as that of the third slide rail 33. In this way, during the movement of the third slide rail 33, the guide block 6 can slide along the guide groove 7, which can provide a certain guiding effect for the movement of the third slide rail 33, so that the movement process of the third slide rail 33 is sufficiently stable, and the corresponding nozzle 34 on the third slide rail 33 will not shake during the movement of the third slide rail 33 to affect the cleaning effect.

[0040] Furthermore, if Figure 1 As shown, one end of the water delivery pipe 35 away from the sprinkler 34 is connected to the on-site water supply pipeline through an automatic hose reel 8.

[0041] In the above embodiment, the automatic hose reel 8 is a prior art. In the car wash industry, the automatic hose reel 8 is often used to store the water hose of the spray gun. In the agricultural field, the automatic hose reel 8 is also often used to store the pesticide hose. The automatic hose reel 8 is generally composed of a hose reel body, a control system and a power system. The hose reel body is responsible for the winding and release of the pipeline, the control system is responsible for controlling the length and speed of the winding, and the power system provides the power for the winding. The specific structure and working principle are not described here. One end of the water pipe 35 of the present application is connected to the adapter shaft port inside the rotating shaft of the automatic hose reel 8, and the port outside the adapter shaft is connected to the water supply pipeline at the power generation equipment site, so that the water supply pipeline can be connected to the water pipe 35 through the automatic hose reel 8 to provide water for it. In addition, the water flow in the water supply pipeline itself has a certain pressure. If the pressure meets the cleaning requirement of the nozzle 34 for the surface of the tube bundle 1, the water in the water supply pipeline can be used directly. If the water pressure in the water supply pipeline cannot meet the cleaning requirement of the nozzle 34 for the surface of the tube bundle 1, a booster pump can be added between the water supply pipeline and the automatic hose reel 8, and the booster pump is used to pressurize the water in the water supply pipeline, thereby ensuring that the water flow pressure can meet the flushing requirement of the nozzle 34 for the surface of the tube bundle 1.

[0042] When the nozzle 34 of the present application moves upward along the surface of the tube bundle 1 or the ladder 2 moves farther in the length direction of the tube bundle 1, the automatic hose reel 8 can release the water pipe 35 thereon to meet the change in the distance between the nozzle 34 and the automatic hose reel 8. When the nozzle 34 moves downward along the surface of the tube bundle 1 or the ladder 2 moves from far to near along the length direction of the tube bundle 1, the automatic hose reel 8 can rewind the excess water pipe 35, which can prevent the excess water pipe 35 from bending and affecting the transmission of water flow inside the pipeline. When the nozzle 34 moves downward along the surface of the tube bundle 1, the automatic hose reel 8 of the present application can also provide power for the reset of the third slide rail 33 by the reeling force on the water pipe 35, and cooperate with the winding motor 451 to stably control the movement distance of the third slide rail 33 and the nozzle 34 thereon.

[0043] Furthermore, the water pipe 35 is a metal armored hose.

[0044] In the above embodiments, the metal armored hose is stronger than the ordinary rubber water hose and can withstand a certain amount of tension while completing the task of transmitting water flow.

[0045] The implementation principle of this embodiment is: after the worker checks and connects the water pipe 35, the automatic hose reel 8 and the water supply pipeline on site, and then checks and confirms the connection point between the water pipe 35 and the nozzle 34, and confirms other related equipment and tools, the cleaning work can begin. At this time, the ladder 2 is located at one end of the tube bundle 1 in the length direction, and the worker first starts the winding motor 451 to reel the first traction rope 43 until the second slide rail 32 and the third slide rail 33 are fully unfolded. In this process, the automatic hose reel synchronously releases the water pipe 35.

[0046] After the nozzle 34 at the end of the third slide rail 33 is aligned with the highest point on the surface of the tube bundle 1, the water supply pipeline starts to supply water, and the nozzle 34 starts to clean the surface of the tube bundle 1. The winding motor 451 starts to release the first traction rope 43 again, and the automatic hose reel 8 starts to rewind the water pipe 35. The second slide rail 32 and the third slide rail 33 will move downward under the action of gravity and the traction of the water pipe 35. When the second slide rail 32 and the third slide rail 33 are all reset to the initial position close to the height of the first slide rail 31, the cleaning work of the high area on the surface of the tube bundle 1 corresponding to the ladder 2 is completed. At this time, the water supply is stopped, and the ladder 2 moves to the next position to be cleaned along the length direction of the tube bundle 1, and then the above operation is repeated.

[0047] When the cleaning device is performing cleaning work, workers can stand on the steel structure platform and use the high-pressure water gun prepared in advance to clean the uncleaned area at the lower part of the previous tube bundle 1. Similarly, when the cleaning device is cleaning the high area of ​​a point on the surface of the tube bundle 1, the worker can manually clean the dirt in the lower area of ​​the surface of the tube bundle 1 at the previous point, so that the worker and the cleaning device can cooperate to complete the cleaning work of the dirt on the surface of the tube bundle 1 efficiently and quickly. Since the cleaning device cleans the part of the high area on the surface of the tube bundle 1, the worker saves the operation of climbing the ladder 2, effectively reducing the risk of high-altitude work caused by it. At the same time, since the cleaning device shares part of the cleaning task of the worker, compared with the purely manual cleaning method in the prior art, it also effectively reduces the labor workload of the worker.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
