Description

Technical Field

[0001] The invention relates to the technical field of radiator cleaning, and in particular to an automatic cleaning device for a gear box heat sink. Background Art

[0002] A large amount of heat is generated during the operation of the gearbox. In order to ensure that the gearbox can work continuously within the set temperature, the gearbox is generally equipped with a heat sink, which is connected to the gearbox and can cool the lubricating oil in the gearbox to ensure the continuous operation of the gearbox. The heat sink is cooled by air cooling. Dust and impurities in the air will be adsorbed on the outer surface of the heat sink to form dirt, which further reduces the heat dissipation capacity of the heat sink. In daily wind turbine maintenance, it is found that the gear box heat sink is covered with dust and catkins, especially in wind farms with heavy dust and strong wind and sand. This affects the heat dissipation effect of the gear box radiator, causes the gear box oil temperature to be high, alarms to stop working, and affects the power generation efficiency. At this time, it needs to be cleaned, and the existing automatic cleaning device may not be convenient for removing dirt and impurities deep in the gaps of the heat sink when working. For example, for some highly sticky oil stains or small particles embedded in the gaps, simple automatic cleaning actions (such as brush cleaning) may not be able to completely remove them. These residual dirt will continue to affect the heat dissipation efficiency. In addition, some heat sinks have complex shapes and structures, and the cleaning head of the automatic cleaning device may not be able to reach all surface areas. For example, some heat sink parts with special shapes or bending angles are easy to become "dead corners" for cleaning, resulting in dirt accumulation in these areas, thereby affecting the heat dissipation performance of the entire heat sink. How to invent an automatic cleaning device for gear box heat sinks to solve these problems has become an urgent problem for technicians in this field. Summary of the invention

In addition, if the viscosity of the oil is not high but it is thickly attached, the cleaning brush will be squeezed during the cleaning process, thereby increasing the squeezing force of the connecting plate on the pressure detection sensor. When the pressure is greater than the set pressure value, the cleaning fluid will also be sprayed from the spray hole through the water pump, and the cleaning brush will be rotated to clean the oil.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example, see Figure 1-Figure 12 , an automatic cleaning device for a gearbox heat sink, comprising a radiator 1 and a support assembly 2, the support assembly 2 comprising a mounting plate 21 and a reinforcement slide bar 22, the mounting plate 21 being connected with a driving screw 23 and a motor 24, and further comprising: A cleaning component 3, which is located on one side of the radiator 1 and is used to clean impurities on the surface of the radiator 1; The moving component 4 is connected to the supporting component 2 , and the moving component 4 is used to adjust the position of the cleaning component 3 .

[0021] Furthermore; two mounting plates 21 and two reinforcing slide bars 22 are each provided, and the two ends of the two reinforcing slide bars 22 are respectively fixedly connected to the side walls of the two mounting plates 21, wherein the side wall of one mounting plate 21 is fixedly connected to the motor 24, one end of the motor 24 is fixedly connected to the driving screw 23, and the mounting plate 21 is fixedly connected to the side wall of the radiator 1; the end of the driving screw 23 away from the motor 24 is rotatably connected to the side wall of the other mounting plate 21, and the side wall of each mounting plate 21 is fixedly connected to a limit switch 25; the moving assembly 4 includes a moving plate 41, the two ends of the moving plate 41 are respectively slidably connected to the two reinforcing slide bars 22, the side wall of the moving plate 41 is threadedly connected to the driving screw 23, and both sides of the moving plate 41 are fixedly connected with sensing rods 43 that cooperate with the limit switch 25.

[0022] The mutual cooperation of the supporting component 2 and the moving component 4: before using the equipment, the mounting plate 21 can be fixed on the side wall of the radiator 1, and the cleaning brush 3301 can be brought into contact with the heat sink on the surface of the radiator 1, and a time collector is set on the surface of the mounting plate 21 on the side of the motor 1 24, and the operation time of the motor 1 24 and the motor 2 42 is timed by the time collector, and the cleaning interval time is set according to the needs, and the motor 1 24 and the motor 2 42 are automatically controlled to complete the cleaning operation. All electrical components in the equipment are powered by an external power supply. In actual use, the motor 1 24 can be started to drive the driving screw 23 to rotate forward, and the threaded connection between the driving screw 23 and the moving plate 41 can be used to drive the cleaning The cleaning component 3 moves on one side of the radiator 1, and the reinforcement slide bar 22 is set to ensure the stability of the moving plate 41 during movement, avoid shaking of the cleaning component 3 when working, and ensure the cleaning effect. In addition, the limit switch 25 is connected with the motor 24 by electrical signals. When the corresponding sensing rod 43 is inserted into the limit switch 25, the motor 24 receives the signal and starts to reverse, thereby driving the driving screw 23 to rotate in the opposite direction, so as to realize the reciprocating movement of the cleaning component 3 and complete the cleaning of impurities on the surface of the dust baffle plate of the radiator 1 to avoid the accumulation and adhesion of external dust and impurities. The limit switch 25 can use a miniature photoelectric switch to limit the moving plate 41 and provide an in-place signal to ensure the smooth reciprocating movement of the moving plate 41.

[0023] Reference Figure 1-Figure 8 , further; the side wall of the movable plate 41 is fixedly connected with a motor 2 42, one end of the motor 2 42 passes through the side wall of the movable plate 41 and is fixedly connected with a rotating plate 44, and the side wall of the rotating plate 44 at one end away from the movable plate 41 is rotatably connected with a limiting sliding post 45; the cleaning component 3 includes a collecting frame 31, one side of the collecting frame 31 is fixedly connected with one end of the movable plate 41, the inner wall of the collecting frame 31 is fixedly connected with the limiting frame 35, the side wall of the collecting frame 31 is provided with a sliding hole 3101, the sliding hole 3101 is connected with the limiting frame 35, and the inner wall of the collecting frame 31 is fixedly connected with a toothed plate 32; the cleaning component 3 also includes a movable frame 34 and a movable frame 36, one end of the movable frame 36 is fixedly connected with a limiting plate 37 The limit plate 37 is slidably connected with the limit frame 35, one end of the movable frame 36 passes through the sliding hole 3101 and is fixedly connected with the limit plate 37, the movable frame 36 is slidably connected with the sliding hole 3101, the movable frame 36 and the limit sliding column 45 are limited and slidable, and one side of the movable frame 34 is slidably connected with the toothed plate 32; the cleaning assembly 3 also includes a cleaning disk 33 and a fixed rod 39, and the cleaning disk 33 and the fixed rod 39 are each provided with a plurality of fixed rods 39, and a plurality of fixed rods 39 are linearly arrayed on the side wall of the movable frame 34, and the fixed rod 39 is rotatably connected with the movable frame 34, and one end of the fixed rod 39 located inside the movable frame 34 is fixedly connected with a toothed disk 38, and the toothed disk 38 is meshed with the toothed plate 32.

[0024] The cleaning component 3 cleans and collects the surface of the radiator 1: while the motor 1 24 is working, the motor 2 42 is started, and the rotating plate 44 on one side of the movable plate 41 is driven to rotate by the motor 2 42, and then the movable frame 36 can move left and right on the inner wall of the slide hole 3101 through the limited sliding between the limit slide column 45 and the movable frame 36. In this process, the movable frame 36 synchronously drives the limit plate 37 to move back and forth inside the limit frame 35, which can not only make the cleaning disk 33 at the upper end of the movable frame 34 do lateral reciprocating motion, but also make it do longitudinal reciprocating motion. The lateral motion can make the cleaning brush 3301 move in the lateral direction of the surface of the radiator 1, and the longitudinal motion can make it move in the longitudinal direction. The combination of the two allows the cleaning brush 3301 to cover the surface area of ​​the entire dust baffle plate of the radiator 1. Avoid dead corners that cannot be cleaned, ensure that dust, dirt and other impurities on all parts of the surface of the radiator 1 can be effectively cleaned, and compared with movement in a single direction, movement in two directions at the same time can speed up the cleaning speed. For example, when cleaning a radiator 1 with a larger area, the entire surface can be cleaned in a shorter time, reducing the total time required for cleaning, thereby improving overall work efficiency and reducing the impact of downtime cleaning time on production and other activities. In addition, the combination of movements in different directions can enable the cleaning components to contact the surface of the radiator 1 from multiple angles. For stubborn dirt, it can be more effectively removed by forces in different directions. For example, lateral movement can generate a lateral friction force on the dirt, and longitudinal movement can generate a longitudinal force. The combined action of forces in multiple directions helps to peel the dirt off the surface of the radiator 1; At the same time, during the left and right movement of the moving frame 34, the fixed rod 39 will be driven to move synchronously. However, through the meshing connection between the toothed disc 38 and the toothed plate 32, the cleaning disc 33 can rotate left and right during the movement of the moving frame 34. Compared with simple linear motion, the rotation of the cleaning disc 33 can cover the cleaning area more comprehensively. For example, when cleaning the irregularly shaped surface of the radiator 1, the rotation allows the cleaning brush 3301 to reach every corner, avoiding cleaning dead corners and ensuring that the dirt is fully removed. In addition, during the rotation, the cleaning brush 3301 will generate additional forces such as centrifugal force, which helps to enhance its cleaning force on the dirt. For impurities such as dust and oil that are more firmly attached, the additional force generated by the rotation of the cleaning disc 33 can assist The cleaning brush 3301 is assisted to better peel off the dirt from the surface, thereby improving the thoroughness of cleaning. Moreover, the continuous rotation enables the cleaning brush 3301 to clean the same area multiple times in a shorter period of time, thereby speeding up the cleaning speed. Taking the cleaning of a large area of ​​the heat sink as an example, the rotation of the cleaning disk 33 allows the cleaning brush 3301 to quickly and intensively contact the surface of the heat sink. Compared with the cleaning method of reciprocating linear motion, the cleaning work can be completed in a shorter time, thereby improving the overall cleaning efficiency. The dust and impurities after cleaning will fall into the collection frame 31 for storage, waiting for subsequent unified cleaning, thereby reducing the workload of the operator. Felt is provided on the inner wall of the collection frame 31, which can effectively attach the cleaned fluff to prevent it from floating and affecting the collection effect.

[0025] Reference Figure 10-12 , further; one end of the cleaning disk 33 is limitedly engaged with the end of the fixing rod 39 away from the toothed disk 38, the cleaning disk 33 is connected with a bolt 3302, the bolt 3302 is threadedly connected to the fixing rod 39, the side wall of the cleaning disk 33 is provided with a plurality of spray holes 3303 distributed in a circumferential array, and the side wall of the cleaning disk 33 is slidably connected with a plurality of cleaning brushes 3301 distributed in a circumferential array, the cleaning brush 3301 is arranged in an inverted "J" shape, and one end of the cleaning brush 3301 located inside the cleaning disk 33 is fixedly connected with a connecting plate 313, and one side of the connecting plate 313 is fixedly connected with a return spring 31 2. One end of the return spring 312 away from the connecting plate 313 is fixedly connected to the inner wall of the cleaning disk 33, and each spray hole 3303 is respectively located between two adjacent groups of cleaning brushes 3301; an annular cover 3304 and a pressure detection sensor 311 are provided inside the cleaning disk 33, the annular cover 3304 is fixedly connected to the inner wall of the cleaning disk 33, the annular cover 3304 is located on one side of the spray hole 3303, the side wall of the annular cover 3304 is fixedly connected to the water pump 310, the pressure detection sensor 311 is fixedly connected to the inner wall of the cleaning disk 33, and the pressure detection sensor 311 is against the side wall of the connecting plate 313.

[0026] The cleaning plate 33 performs deep cleaning of the surface of the radiator 1: a liquid filling nozzle is provided on one side of the cleaning plate 33, and a cleaning liquid is filled into the interior of the cleaning plate 33 through the liquid filling nozzle. The cleaning liquid can be an organic solvent or a special cleaning agent for the heat sink. When the cleaning plate 33 cleans the surface of the radiator 1 through the cleaning brush 3301, when there is relatively viscous oil or catkins that are difficult to clean attached to the surface of the radiator 1, a relatively strong pulling force will be applied to the corresponding cleaning brush 3301, and at this time, the cleaning brush 3301 is stretched, and the reset spring 312 is extended. At this moment, the pressure detection sensor 311 There will be some pressure values ​​weakened on the surface, and the pressure detection sensor 311 is connected to the water pump 310 by electrical signals. When the surface pressure of the pressure detection sensor 311 is less than the set pressure value, the water pump 310 starts to transport the cleaning liquid inside the cleaning disk 33 to the inside of the annular cover 3304. The cleaning liquid is evenly sprayed out from the spray hole 3303 through the flow of the annular cover 3304, thereby cleaning the oil stains or wetting the attached catkins to loosen them, so as to improve the cleaning effect. In addition, if the viscosity of the oil stains is not high but they are thickly attached, the cleaning brush 3301 can be used to clean them. During the cleaning process, the cleaning brush 3301 will be squeezed, thereby increasing the squeezing force of the connecting plate 313 on the pressure detection sensor 311. When the pressure is greater than the set pressure value, the cleaning liquid is also sprayed out from the spray hole 3303 by the water pump 310, and the cleaning of the oil stains is achieved in conjunction with the rotation of the cleaning brush 3301. In the normal cleaning process, when the adhesion of impurities on the surface of the radiator 1 is not high, it can be cleaned directly without causing a large squeezing force on the cleaning brush 3301. In addition, the cleaning brush 3301 set in an inverted "J" shape can not only improve the cleaning of catkins The cleaning force can not only increase the cleaning area, but also increase the area of ​​​​the oil stains attached to the surface of the cleaning brush 3301 during cleaning. When there is more oil stains attached to the surface of the cleaning brush 3301, the overall weight will also increase, so that the connecting plate 313 squeezes the pressure detection sensor 311, causing the cleaning liquid to spray out to complete its own cleaning, reduce the adhesion of oil stains, and ensure the cleaning effect. In addition, the cleaning disk 33 and the fixing rod 39 are fixed by bolts 3302, which can facilitate the disassembly and installation of the two, thereby facilitating targeted maintenance and replacement of the cleaning disk 33 and reducing maintenance costs.

[0027] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
