Description

Technical Field

[0001] The present invention relates to the technical field of high-pressure cleaning equipment for power plants, and particularly to an automatic walking device. Background Art

[0002] Since air-cooled units can save about 65% of water resources compared to wet-cooled units, China has clearly put forward to vigorously develop air-cooled units. However, through actual operation, some deficiencies and problems have gradually emerged in air-cooled units. The most important one is that due to the long-term operation of the heat dissipation fins in the open air, impurities such as fine sand, dust, and willow catkins in the air are deposited on the heat exchange fins. The ash, scale, and impurities on the surface of the heat exchange fins will, on the one hand, reduce the area of the air passage, and on the other hand, increase the heat transfer resistance of the heat exchange fins, greatly reducing the heat exchange capacity of the heat exchange fins, resulting in an increase in the vacuum of the condenser and a decrease in the unit efficiency. In addition, the dirt on the heat exchange fins will also cause under-deposit corrosion of the metal, shortening the service life of the heat exchange fins. Therefore, it is necessary to formulate countermeasures to clean the dirt, reasonably perform high-pressure water flushing, and optimize the flow field distribution on the air side, which is of great significance for improving the heat transfer effect of the condenser.

[0003] The existing method for flushing is that workers use a high-pressure water gun to flush the heat dissipation fins, aiming the water gun nozzle at the surface of the fins, and removing impurities such as dust and dirt on the fins through the impact force of the high-pressure water flow; or moving the position by manually pushing the cleaning rack. However, since the cleaning rack is equipped with components such as water pipes and is heavy, manual pushing operation is very inconvenient, with a large labor intensity and low efficiency.

[0029] The object of the present invention is to provide an automatic walking device to solve the problems existing in the prior art, which can realize automatic walking, improve the operation convenience and reduce the labor intensity.

[0030] To make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Embodiment 1

[0032] This embodiment provides an automatic walking device, mainly but not limited to being used for flushing power plant heat dissipation fins, such as Figures 1 to 4As shown, it includes a traveling mechanism; the traveling mechanism includes a controller, a main body frame 20, a slide rail frame, a rack 32, a driver 21, a driving wheel 22 and at least one supporting wheel 23; the controller is communicatively connected to the driver 21; the main body frame 20 is used to connect with the cleaning frame 13; the slide rail frame has a mounting plate 31 parallel to the power plant heat dissipation fins 40, and the mounting plate 31 is located above the lower end of the power plant heat dissipation fins 40; the rack 32 is fixedly arranged on the upper plane of the mounting plate 31; the driver 21 (such as a reduction motor) is arranged on the main body frame 20 (fixed to the main body frame 20 by screws), and the output end of the driver 21 is in transmission connection with the driving wheel 22, and the output end of the driver 21 can drive the driving wheel 22 to rotate; the driving wheel 22 meshes with the rack 32, and the driving wheel 22 can move along the first direction on the rack 32; in the first direction, the supporting wheel 23 is rotatably arranged on the main body frame 20 in front of and / or behind the driving wheel 22; one end of the mounting plate 31 close to the power plant heat dissipation fins 40 forms a guide rail; the supporting wheel 23 includes a rolling wheel 231 and a limiting plate 232, the limiting plate 232 is fixedly arranged at one end of the rolling wheel 231, and the end of the limiting plate 232 away from the rolling wheel 231 is rotatably connected to the main body frame 20; the rolling surface of the rolling wheel 231 is in rolling contact with the upper plane of the guide rail, and the limiting plate 232 is located on one side of the guide rail (the size of the limiting plate 232 is larger than the outer diameter of the rolling wheel 231), for example, the edge of the limiting plate 232 can protrude from the lower plane of the guide rail.

[0033] The controller sends instructions to the driver 21. After receiving the signal, the driver 21 starts, and its output drives the driving wheel 22 to rotate. Since the driving wheel 22 meshes with the rack 32 fixed on the upper plane of the slide rail frame mounting plate 31, according to the transmission principle of the gear rack 32, the rotation of the driving wheel 22 is converted into a movement along the first direction on the rack 32, thereby driving the entire main frame 20 and the cleaning frame 13 connected to the main frame 20 to move along the direction of the power plant heat dissipation fins 40, realizing automatic walking. The guide rail formed at one end of the slide rail frame mounting plate 31 close to the power plant heat dissipation fins 40 cooperates with the supporting wheel 23. The rolling surface of the rolling wheel 231 of the supporting wheel 23 is in rolling contact with the upper plane of the guide rail, providing a stable guiding effect for the movement of the main frame 20, enabling the walking device to accurately move along the direction of the heat dissipation fins, avoiding situations such as deviation, reducing the workload of the operator to adjust the walking direction, and improving the operation convenience. The limiting plate 232 on the supporting wheel 23 is fixed at one end of the rolling wheel 231, and the edge of the limiting plate 232 can protrude from the lower plane of the guide rail and is located on one side of the guide rail. When the main frame 20 shakes or is interfered by external forces during movement, the limiting plate 232 can prevent the rolling wheel 231 from detaching from the guide rail, playing a limiting role, further ensuring the stability and reliability of the walking device, reducing the operator's worry about the operating state of the device and the monitoring cost, and reducing the labor intensity. The controller is communicatively connected to the driver 21. The operator only needs to set the operating parameters of the walking device, such as walking speed, walking distance, etc., through the controller, and the controller can accurately control the operation of the driver 21 according to the preset instructions, and then control the rotation of the driving wheel 22 and the movement of the main frame 20. This automatic control method does not require the operator to manually and frequently adjust and intervene in the walking process of the device, greatly improving the operation convenience and reducing the labor intensity. The main frame 20 is used to connect to the cleaning frame 13. The overall design of the walking mechanism enables the cleaning frame 13 to move automatically with the walking device. When cleaning the power plant heat dissipation fins 40, the operator does not need to manually push the cleaning frame 13 to move between the heat dissipation fins, reducing the walking and operation difficulty of the operator in a narrow space, reducing the labor intensity. At the same time, this integrated structural design also improves the efficiency and convenience of the entire cleaning operation.

[0034] Among them, regarding the relevant descriptions of the first direction and the second direction:

[0035] Specifically, the overall power plant heat dissipation fins 40 are arranged in an inclined posture. Its length direction is parallel to the first direction, and its width direction is parallel to the extending direction of the length of the slide 10 and the second direction; the second direction is the extending direction of the length of the slide 10.

[0036] Among them, regarding the descriptions of other components of the walking mechanism:

[0037] In the optional solution of this embodiment, preferably, such asFigure 1 As shown, it further includes a slide 10, which is arranged above the power plant cooling fins 40. There is a spacing between the slide 10 and the power plant cooling fins 40. A cleaning rack 13 is arranged on the slide 10; a plurality of pedal rods 11 are fixedly arranged on the slide 10, and the pedal rods 11 are arranged in sequence along the second direction, and the second direction is perpendicular to the first direction; and the main frame 20 is fixedly connected to the lower end of the slide 10. Being arranged above the power plant cooling fins 40 makes full use of the space above the power plant cooling fins 40, does not occupy additional ground space, makes the overall layout more compact and reasonable, and improves the space utilization rate; since the slide 10 is located above the cooling fins, when the operator performs related operations through the slide 10, the operator can conveniently observe the working state of the cooling fins and timely discover possible problems of the cooling fins, such as whether there is abnormal heating, damage, etc., which is convenient for timely maintenance and upkeep; the pedal rods 11 provide a foot support point for the operator to walk on the slide 10, enabling the operator to move more stably on the slide 10, especially when getting on and off the slide 10, which helps to control the speed and maintain body balance, reduces the risk of slipping and injury, and ensures the safety of the operator.

[0038] Specifically, the slide 10 is made of an aluminum slide 10.

[0039] Specifically, the cleaning rack 13 can slide on the slide 10 along its length extension direction. And a drag chain mechanism for cooperating with the cleaning rack 13 is arranged on the slide 10, which is used for the following movement of the pipeline. It is prior art and will not be elaborated here.

[0040] In an alternative embodiment of the present embodiment, preferably, as Figure 1 shown, the upper end of the slide 10 is slidably arranged at the upper end of the power plant cooling fins 40 along the first direction through an upper slide rail. The setting of the upper slide rail provides a smooth track for the movement of the slide 10, reduces the direct friction between the slide 10 and the cooling fins, reduces the wear degree of the equipment, extends the service life of the equipment, and at the same time, can also effectively avoid the jamming phenomenon caused by excessive friction, makes the movement of the automatic walking device smoother, and ensures the stability and continuity of the operation.

[0041] Among them, the setting description of the relevant components on the main frame 20:

[0042] In an alternative embodiment of the present embodiment, preferably, as Figures 1 to 3As shown in the figure, the driver 21 is fixedly arranged on one side of the main body frame 20 away from the power plant heat dissipation fins 40, and the output shaft of the driver 21 passes through the main body frame 20 and is located on the side of the main body frame 20 close to the power plant heat dissipation fins 40; the driving wheel 22 is located on the side of the main body frame 20 away from the power plant heat dissipation fins 40, the rotating shaft of the driving wheel 22 is rotatably arranged on the main body frame 20, and the end of the rotating shaft of the driving wheel 22 is located on the side of the main body frame 20 close to the power plant heat dissipation fins 40; the output shaft of the driver 21 is in transmission connection with the rotating shaft of the driving wheel 22 through a transmission member (the transmission member can be a combination of a belt and a pulley, or a combination of a chain 25 and a sprocket. Preferably, it is a combination of a chain 25 and a sprocket. For example, a first sprocket is fixed on the output shaft of the driver 21, and a second sprocket is fixed on the rotating shaft of the driving wheel 22. The first sprocket and the second sprocket are both located on the same side of the main body frame 20, and the first sprocket is in transmission connection with the second sprocket through the chain 25). Fixing the driver 21 on the side of the main body frame 20 away from the power plant heat dissipation fins 40 can keep it away from the heat dissipated by the heat dissipation fins and possible adverse environmental factors such as dust and water vapor, reduce the influence of these factors on the performance and service life of the driver 21, improve the stability and reliability of the driver 21 during operation, and reduce the probability of faults; the driver 21 is installed outside the main body frame 20, which is convenient for staff to install, debug and perform daily maintenance operations. There is no need to find an installation space or perform maintenance operations in the complex heat dissipation fin structure, which improves work efficiency and reduces maintenance costs; the driving wheel 22 is located on the side of the main body frame 20 away from the power plant heat dissipation fins 40, its rotating shaft is rotatably arranged on the main body frame 20, and the end of the rotating shaft is located on the side of the main body frame 20 close to the power plant heat dissipation fins 40. This layout makes reasonable use of the space on both sides of the main body frame 20, which not only ensures the stable installation position of the driving wheel 22, but also enables the transmission structure to achieve efficient transmission in a limited space, making the structure of the entire automatic walking device more compact and reasonable.

[0043] In an alternative embodiment of the present embodiment, preferably, as Figure 1 shown, in the first direction, an auxiliary guiding wheel 12 is rotatably arranged on the front side and the rear side of the lower end of the slide 10. The auxiliary guiding wheel 12 has a rolling groove, and the side of the guiding rail close to the power plant heat dissipation fins 40 is located in the rolling groove. The rolling groove of the auxiliary guiding wheel 12 cooperates with the guiding rail, which can ensure that the automatic walking device moves precisely along the guiding rail in the first direction, prevent the device from shifting or shaking during operation, improve the accuracy and stability of walking, ensure that the device can accurately reach the predetermined position, and perform corresponding operations on the power plant heat dissipation fins 40; the rotatable arrangement of the auxiliary guiding wheel 12 changes the friction between the device and the guiding rail from sliding friction to rolling friction during the movement of the device. The rolling friction coefficient is small, which can effectively reduce the friction between the device and the guiding rail, reduce the wear degree of components, extend the service life of the guiding rail and the auxiliary guiding wheel 12, and at the same time reduce energy consumption, making the device operation more energy-saving.

[0044] In an alternative embodiment of the present embodiment, preferably, as Figure 1 and Figure 2 shown, a protective cover 24 is fixedly provided on one side of the main frame 20 close to the power plant heat dissipation fin 40, and the upper end of the protective cover 24 extends away from the power plant heat dissipation fin 40. The protective cover 24 can prevent dust, debris, etc. from entering the interior of the main frame 20, avoiding wear, corrosion or blockage of key components such as the internal driver 21, chain 25, and driving wheel 22, thereby extending the service life of the device and ensuring the normal operation of the automatic walking device; its extended upper end can play a certain shielding role, reducing the splashing of cleaning liquid onto components such as the corresponding side driver 21.

[0045] Specifically, each supporting wheel 23 and auxiliary guiding wheel 12 play a role in orienting and preventing derailment of the entire walking mechanism.

[0046] Among them, to improve the running stability, the following related settings can also be made:

[0047] In an alternative embodiment of the present embodiment, preferably, it further includes a locking mechanism, and the locking mechanism includes a locking gear and an electric control telescopic rod; the driving wheel 22 is rotatably arranged on the main frame 20 through a driving rotating shaft, the locking gear is fixedly arranged on the driving rotating shaft, the electric control telescopic rod is arranged on the main frame 20, and the telescopic end of the electric control telescopic rod can extend into a tooth groove on the outer side wall of the locking gear to lock the rotation of the locking gear around the axis of the driving rotating shaft. When the automatic walking device reaches the designated position, the telescopic end is extended into the tooth groove of the locking gear through the electric control telescopic rod, which can accurately lock the rotation of the driving wheel 22, thereby accurately fixing the device at the current position, ensuring that it will not move during related operations, and improving the accuracy and stability of the operation.

[0048] Specifically, the setting of the locking mechanism can achieve the position locking of the main frame 20 on the slide rail frame, so that it can reduce the influence of movement on the cleaning operation when it does not need to move.

[0049] In an alternative embodiment of the present embodiment, preferably, as Figures 1 to 3 shown, at least one supporting wheel 23 is provided on both the upper plane and the lower plane of the mounting plate 31, and the limiting plate 232 of the supporting wheel 23 is located on the side of the guide rail close to the power plant heat dissipation fin 40. The supporting wheels 23 on the upper and lower planes of the mounting plate 31 are in contact with the guide rail, which can provide support for the mounting plate 31 and the entire automatic walking device from multiple points, disperse the weight of the device, make the device more stable during walking, avoid shaking or tilting caused by uneven local stress, and help ensure the normal operation and operation accuracy of the device; the supporting wheels 23 can be arranged in a way that two are provided on the upper side and two are provided on the lower side.

[0050] In an alternative embodiment of the present embodiment, preferably, a wheel shaft of the abutting wheel 23 is fixed to the side of the limiting plate 232 of the abutting wheel 23 away from the rolling wheel 231. An installation hole is provided on the main body frame 20. The wheel shaft of the abutting wheel 23 passes through the installation hole and is fixedly connected to a limiting member; a spring is sleeved on the wheel shaft of the abutting wheel 23 between the limiting plate 232 and the main body frame 20. The setting of the spring provides a certain tension for the abutting wheel 23, so that it maintains a stable contact area with the upper plane of the mounting plate 31.

[0051] Among them, the descriptions of other related settings are as follows:

[0052] In an alternative embodiment of the present embodiment, preferably, as Figures 1 to 3 shown, the slide rail frame is an L-shaped plate 30. The L-shaped plate 30 includes a first side plate and a second side plate; the first side plate and the second side plate are perpendicularly fixed, and one side of the first side plate is fixedly connected to one side of the second side plate; the first side plate is fixedly arranged at the lower end of the power plant cooling fin 40, and the second side plate is parallel to the power plant cooling fin 40, and the second side plate forms the mounting plate 31. The structure of the L-shaped plate is relatively simple. The fixation of the first side plate to the cooling fin and the setting of the second side plate as the mounting plate 31 both enable the convenient installation and fixation of the various components of the automatic walking device. This simple structure reduces the complexity and difficulty in the installation process, and reduces the installation cost and time.

[0053] Specifically, the driver 21 is an existing device, and a speed reducer can be used, which is equipped with an encoder to achieve precise control.

[0054] Specifically, the movement of the slide 10 will drive the cleaning frame 13 to move in the first direction, and cooperate with the reciprocating movement of the cleaning frame 13 on the slide 10 in the second direction, so as to clean the surface of the cooling fins.

[0055] Specifically, the controller can automatically operate by controlling the driver 21, and can be operated locally or remotely.

[0056] Specifically, under the drive of the driver 21, the output shaft of the driver 21 rotates, drives the driving wheel 22 through the chain 25, so that the driving wheel 22 meshes with the rack 32, driving the entire aluminum slide 10 and the cleaning frame 13 to reciprocate in the first direction. Nozzles are provided on the cleaning frame 13, and the nozzles can spray high-pressure cleaning water to wash the air-cooled cooling fins, achieving the effect of cleaning and cooling the air-cooled cooling fins.

[0057] Specifically, the flushing time of the entire air-cooled cooling fins can be optimized and controlled by adjusting the speed of the driver 21.

[0058] In the present invention, specific examples are used to illustrate the principles and implementation manners of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manners and application scopes.
