Description

Technical Field

[0001] This utility model relates to maintenance equipment for coolers, and in particular to a cleaning device. Background Technology

[0002] In related technologies, nuclear power plants located in northern regions experience a surge in willow catkins every spring. Since the main transformers are all placed outdoors, the strong airflow from the transformer cooling fans causes large amounts of catkins to adhere to the surface of the cooler fins or even enter the fins, blocking the cooling air ducts and severely affecting the ventilation and heat dissipation of the main transformer coolers, thus impacting the normal operation of the coolers and the main transformers. Manually cleaning the catkins is not only time-consuming and labor-intensive but also lacks safety. Related technologies also include a cleaning device for power transformer coolers, which uses brushes on both sides of the cooler's ventilation plates. These brushes can move up and down along the ventilation plates to automatically clean them. However, this cleaning device cannot be adjusted according to actual conditions to achieve optimal cleaning results, lacking adaptability. Utility Model Content

[0032] Reference Figure 1 and Figure 2 The cleaning device includes a mounting assembly 100, a cleaning assembly 200, and a moving drive mechanism 300. The mounting assembly 100 includes a fixed base 120 and a filter screen 110 mounted on the fixed base 120. The fixed base 120 is used to mount the object to be cleaned so that the filter screen 110 can cover the ventilation opening of the object. The cleaning assembly 200 includes a brush wheel 210 and a brush wheel drive mechanism 220. The brush wheel 210 is disposed opposite to the filter screen 110 and its position relative to the filter screen 110 is adjustable in the direction close to the filter screen 110. The brush wheel drive mechanism 220 is connected to the brush wheel 210 and is used to drive the brush wheel 210 to rotate around its rotation axis when the brush wheel 210 abuts against the filter screen 110, thereby cleaning the filter screen 110. The brush wheel drive mechanism 220 is movably mounted on the fixed base 120 and can move relative to the fixed base 120. The moving drive mechanism 300 is mounted on the mounting assembly 100 and connected to the brush wheel drive mechanism 220. The moving drive mechanism 300 drives the brush wheel drive mechanism 220 to move relative to the fixed base 120, so that the brush wheel 210 can move to different positions on the filter screen 110. In this embodiment, the object to be cleaned is a cooler. It is understood that the object to be cleaned is not limited to a cooler, and the cleaning device can also be applied to other devices and equipment.

[0033] When installing the cleaning device described above on the cooler, the fixing base 120 of the mounting assembly 100 is installed on the air inlet side of the cooler, so that the filter screen 110 covers the air inlet of the cooler. The filter screen 110 can trap dirt such as willow catkins and dust, preventing dirt from entering the cooler. When too much dirt accumulates on the filter screen 110, it can be cleaned. Specifically, the brush wheel 210 can be adjusted to abut against the filter screen 110, and the brush wheel 210 is driven to rotate by the brush wheel drive mechanism 220. At the same time, the brush wheel drive mechanism 300 is driven to move the brush wheel drive mechanism 220 to different positions on the filter screen 110, and the rotating brush wheel 210 cleans the filter screen 110. When using the cleaning device, the position of the brush wheel 210 can be adjusted according to the amount or type of dirt, thereby adjusting the distance and pressure between them relative to the filter screen 110, and thus adjusting the cleaning effect. It can adapt to different situations and is flexible in use. Specifically, when there is a lot of dirt accumulated or the dirt is firmly stuck to the filter screen 110, the brush wheel 210 can be adjusted closer to the filter screen 110 to increase the pressure between the filter screen 110 and the brush wheel 210 before cleaning, thereby improving the cleaning effect. When there is less dirt, or dirt that is easy to fall off, the brush wheel 210 can be adjusted further away from the filter screen 110 to reduce the pressure between them, reduce the friction of the brush wheel 210, improve cleaning efficiency, and protect the brush wheel 210.

[0034] In some embodiments, the mobile drive mechanism 300 and the brush wheel drive mechanism 220 can operate simultaneously, so that the brush wheel 210 can rotate and move simultaneously to perform cleaning. In some embodiments, the mobile drive mechanism 300 and the brush wheel drive mechanism 220 may also not operate simultaneously. For example, the mobile drive mechanism 300 drives the brush wheel drive mechanism 220 to move back and forth, and the brush wheel drive mechanism 220 drives the brush wheel 210 to rotate at a predetermined position or at a predetermined time.

[0035] In this embodiment, the filter screen 110 can be made of 304 stainless steel to prevent willow catkins, with a mesh size of 2mm. The inner and outer layers are covered with stainless steel wires of 1.5mm diameter, spaced 30mm apart, with a mesh size of approximately 25-30 and a wire diameter of 0.2-0.3mm. The protective screen is fixedly installed in sections on the air inlet side of the cooler. To increase flatness and improve wind pressure resistance, reinforcing structures can be added to the willow catkin screen support, such as reinforcing plates or reinforcing strips.

[0036] In this embodiment, two brush wheels 210 are arranged side by side to clean the filter screen 110, resulting in a good cleaning effect. It is conceivable that in some embodiments, the number of brush wheels 210 is not limited to two; for example, there may be more than two, or only one, depending on the actual situation. In this embodiment, some limiting structures can be provided to limit the extreme positions of the brush wheels 210.

[0037] In this embodiment, the length of the brush wheel 210 is equal to the width of the filter screen 110, and the length direction of the brush wheel 210 is parallel to the width direction of the filter screen 110. The moving drive mechanism 300 is configured to drive the brush wheel drive mechanism 220 to reciprocate along the length direction of the filter screen 110, so that the brush wheel 210 can completely clean the entire filter screen 110, resulting in high cleaning efficiency. In the embodiment shown in the accompanying drawings, the width direction of the filter screen 110 is the left-right direction, and the length direction is the up-down direction. It is understood that in some embodiments, the width direction of the filter screen 110 may also correspond to the up-down direction, while the length direction may correspond to the left-right direction.

[0038] It is conceivable that in some embodiments, the length of the brush wheel 210 may not be equal to the width of the filter screen 110. For example, the length of the brush wheel 210 may be less than the width of the filter screen 110. The entire filter screen 110 is cleaned by driving the brush wheel drive mechanism 220 to move in multiple directions.

[0039] In this embodiment, the brush wheel 210 is connected to an axle 230 at its longitudinal end. The brush wheel drive mechanism 220 includes a drive member 221, a drive wheel 222, a driven wheel 223, and a drive belt 224. The driven wheel 223 is connected to and coaxially arranged with the axle 230. The drive belt 224 is sleeved on the drive wheel 222 and the driven wheel 223 and is tensioned. The drive member 221 is connected to the moving drive mechanism 300 and to the drive wheel. The drive member 221 drives the drive wheel 222 to rotate, thereby driving the driven wheel 223 to rotate via the drive belt 224. With the above structure, the drive member 221 drives the brush wheel 210 to rotate via the drive belt 224. The structure is simple and easy to implement. Moreover, the structure of the drive belt 224 allows for easy adjustment of the tension of the drive belt 224 by adjusting its length or by setting an adjustable abutment wheel to abut against it. This facilitates the subsequent implementation of a structure where the position of the brush wheel 210 is independently adjustable.

[0040] In the embodiments, the drive element 221 is used to provide power to drive the brush wheel 210 to rotate. Specifically, it can be a motor. Of course, it is conceivable that in some embodiments, the drive element 221 is not limited to a motor. For example, it can also be a rotary cylinder or other devices that can drive components to rotate.

[0041] In the embodiment, the drive component 221 of the brush wheel drive mechanism 220 can adopt some speed-adjustable structure, thereby adjusting the rotational speed of the brush wheel 210.

[0042] In this embodiment, the output shaft of the drive member 221 is coaxially connected to the drive wheel 222, thereby driving the drive wheel 222 to rotate. Of course, it is conceivable that the output shaft of the drive member 221 can also drive the drive wheel 222 to rotate via a gear set, belt drive, or other similar structure. In this embodiment, the drive belt 224 can be a chain belt, in which case the drive wheel 222 and the driven wheel 223 can be sprockets; or the drive belt 224 can be a belt, in which case the drive wheel 222 and the driven wheel 223 can be synchronous pulleys; the drive belt 224 can also be a chain plate, and the drive wheel 222 and the driven wheel 223 can adopt a structure adapted to the chain plate.

[0043] It is conceivable that the brush wheel drive mechanism 220 is not limited to the structure described above. For example, the brush wheel drive mechanism 220 may include a motor that drives each brush wheel 210 to rotate via a gear set; or the brush wheel drive mechanism 220 may use a motor that corresponds one-to-one with each brush wheel 210, with the motor's output shaft connected to the corresponding brush wheel 210. The brush wheel drive mechanism 220 may also use a cylinder or an electric cylinder, with the piston rod of the cylinder or electric cylinder connected to a rack, and the brush wheels 210 coaxially connected to gears. The rack and gears mesh, and when the extension rod of the cylinder or electric cylinder actuates, it can drive the gears to rotate via the rack, thereby driving the brush wheels 210 to rotate. It is understood that there are many implementation methods in the art for achieving rotational drive of rotating components, and those skilled in the art can configure them according to the actual situation.

[0044] In this embodiment, the fixed base 120 includes two guide rails 121, which are respectively connected to opposite sides of the filter screen 110 and arranged parallel to each other. The brush wheel drive mechanism 220 includes a movable seat 225, with the drive component 221 mounted on the movable seat 225. Both ends of the movable seat 225 are movably mounted on the two guide rails 121 and can move along the guide rails 121. The brush wheel 210 is mounted on the movable seat 225. The above structure is simple and provides stable support for the brush wheel drive mechanism 220, ensuring smooth movement of the brush wheel drive mechanism 220. It is conceivable that the fixed base 120 is not limited to a structure with two guide rails 121; for example, it could be a single guide rail 121, with the middle of the movable seat 225 movably mounted on this guide rail 121; or the fixed base 120 could use three or more guide rails 121 for the movable seat 225 to be movably connected.

[0045] In this embodiment, the movable seat 225 is connected to a roller, and the guide rail 121 is provided with a guide groove. The roller is movably disposed in the guide groove, thereby realizing the cooperation between the movable seat 225 and the guide rail 121. It is conceivable that the connection between the movable seat 225 and the guide rail 121 is not limited to the above-described method. For example, the movable seat 225 can be equipped with a slider adapted to the guide rail 121 for connection, or the guide rail 121 can be a guide rod, and the movable seat 225 can be equipped with a linear sliding bearing for cooperation.

[0046] In this embodiment, to achieve an adjustable position of the brush wheel 210 relative to the filter screen 110 in the direction approaching the filter screen 110, the brush wheel drive mechanism 220 can be configured as a whole to be position-adjustable. Specifically, in one embodiment, the roller connected to the movable seat 225 of the brush wheel drive mechanism 220 can be configured to be front-to-back adjustable: the roller can be connected to a roller frame, which can be provided with multiple gear mounting holes. Fixing screws pass through these holes and lock the roller frame to the movable seat 225. The gear mounting holes are arranged along the direction approaching and away from the filter screen 110 (front-to-back direction). Therefore, when different gear mounting holes are used to install the roller frame, the front-to-back position of the roller can be adjusted, thereby achieving front-to-back position adjustment of the brush wheel drive mechanism 220 relative to the filter screen 110. In some embodiments, the gear mounting holes can also be replaced by front-to-back extending slots, which also achieve front-to-back position adjustment. It is conceivable that other structures can also be used to achieve the overall position adjustment of the brush wheel drive mechanism 220. For example, a height-adjustable linear guide rail can be set on the fixed base 120, and the brush wheel drive mechanism 220 can be movably mounted on the linear guide rail, thereby adjusting the overall front and rear position of the brush wheel drive mechanism 220 through the linear guide rail.

[0047] It is understood that in some embodiments, this can also be achieved by making the brush wheel 210 independently adjustable in position. Specifically, multiple mounting holes can be provided in the brush wheel drive mechanism 220, arranged along the direction of approaching and moving away from the filter screen 110. The axle 230 is adapted to be rotatably connected to each mounting hole, thereby achieving position adjustment. Alternatively, in some embodiments, a slider that can slide along the direction of approaching and moving away from the filter screen 110 is provided on the brush wheel drive mechanism 220, and an adjustment mechanism for adjusting the position of the slider is provided. The axle 230 of the brush wheel 210 is rotatably mounted on the slider, and the position of the axle 230 is adjusted by adjusting the position of the slider. The adjustment mechanism is, for example, a screw with a threaded connection provided on both sides of the slider in the sliding direction. The end of the screw presses against the slider to position the slider, and the slider position is adjusted by rotating the screws on both sides of the slider. The adjustment mechanism can also be a lead screw, which is rotatably mounted. The slider is provided with a matching lead screw nut to cooperate with the lead screw, and the slider position is adjusted by rotating the lead screw. It is understood that there are many ways in the art to adjust the position of a component relative to another component in a predetermined direction, and those skilled in the art can configure it according to the actual situation.

[0048] In the aforementioned implementation structure where the position of the brush wheel 210 relative to the filter screen 110 is adjustable in the direction close to the filter screen 110, the adjustment is mainly manual. However, it is conceivable that automatic adjustment can also be used in some embodiments. For example, the brush wheel drive mechanism 220 is connected to the fixed base 120 via a lifting driver. The lifting driver is, for example, an electric push rod or an electric lifting platform. The lifting driver is movably mounted on the fixed base 120, and the brush wheel drive mechanism 220 is fixed to the lifting driver. The lifting driver is used to drive the brush wheel drive mechanism 220 and its connected brush wheel 210 to move or reset relative to the filter screen 110 in the direction close to the filter screen 110, thereby achieving automatic adjustment without manual operation, making operation convenient.

[0049] In this embodiment, a protective cover 500 is provided on the cleaning component 200, which provides better protection for the structure of the cleaning component 200.

[0050] In this embodiment, the cleaning device also includes a dust collection tray 400, which is installed on the mounting assembly 100 and located below the filter screen 110. The dust collection tray 400 is used to collect dirt swept off by the brush wheel 210, thereby preventing dirt from falling into the external environment.

[0051] In this embodiment, the moving drive mechanism 300 includes a fixed pulley 310, a take-up drum 320, a take-up driver 330, and a pull rope 340. The fixed pulley 310 is disposed on the upper side of the filter screen 110. One end of the pull rope 340 is connected to the take-up drum 320, and the other end of the pull rope 340 is connected to the brush wheel drive mechanism 220. The pull rope 340 is wound around the fixed pulley 310. The take-up driver 330 is installed on the brush wheel drive mechanism 220 and connected to the take-up drum 320. The take-up driver 330 is used to drive the take-up drum 320 to rotate so as to take up or unwind the pull rope 340. When the take-up driver 330 drives the take-up drum 320 to rotate, it can wind up the pull rope 340. The pull rope 340 lifts the brush wheel drive mechanism 220 through the fixed pulley 310, thereby raising the brush wheel drive mechanism 220. When the take-up driver 330 drives the take-up drum 320 to rotate in the opposite direction, it can release the pull rope 340, thereby lowering the brush wheel drive mechanism 220. The structure of using the fixed pulley 310 and the pull rope 340 to drive the movement of the brush wheel drive mechanism 220 is simple and easy to maintain.

[0052] In this embodiment, the other end of the pull rope 340 is fixed to one end of the brush wheel drive mechanism 220 in the left-right direction, and the take-up drum 320 is set at the other end of the brush wheel drive mechanism 220 in the left-right direction. Pullers 310 are provided above both the other end of the pull rope 340 and the take-up drum 320. With this structure, the force distribution of the mechanism is relatively balanced, and the brush wheel drive mechanism 220 can rise and fall smoothly.

[0053] Reference Figure 3 and Figure 4 In another embodiment of the cleaning device, the structure of the moving drive mechanism 300 is similar to... Figure 1 and Figure 2 The structures of the embodiments shown are different. Figure 3 and Figure 4In the illustrated embodiment, the moving drive mechanism 300 includes a fixed pulley 310, a movable pulley 350, a take-up drum 320, a take-up driver 330, and a pull rope 340. The fixed pulley 310 is disposed on the upper side of the filter screen 110, and the movable pulley 350 is connected to the brush wheel drive mechanism 220. The portion of the fixed base 120 located on the upper side of the filter screen 110 is provided with a pull rope connecting portion 130. One end of the pull rope 340 is connected to the take-up drum 320, and the other end of the pull rope 340 is fixed to the pull rope connecting portion 130. The pull rope 340 is sequentially wound around the fixed pulley 310 and the movable pulley 350. The take-up driver 330 is installed on the fixed base 120 and connected to the take-up drum 320. The take-up driver 330 can drive the take-up drum 320 to rotate in order to take up or unwind the pull rope 340. When the take-up driver 330 drives the take-up drum 320 to rotate, it can wind up the pull rope 340. The pull rope 340 lifts the brush wheel drive mechanism 220 through the fixed pulley 310 and the movable pulley 350, causing it to rise. When the take-up driver 330 drives the take-up drum 320 to rotate in the opposite direction, it can release the pull rope 340, thereby allowing the brush wheel drive mechanism 220 to descend. The use of the movable pulley 350 and the fixed pulley 310 to drive the brush wheel drive mechanism 220 to rise and fall is labor-saving and reduces the load on the take-up driver 330.

[0054] In this embodiment, the brush wheel drive mechanism 220 has a movable pulley 350 at each end along the left-right direction. A fixed pulley 310 and a rope connection 130 are respectively positioned vertically opposite to the two movable pulleys 350. The winding drum 320 is positioned below the movable pulley 350 corresponding to the fixed pulley 310.
