Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a water collection tank cleaning device. Background Art

[0002] The filter tank of the water plant is used for filtering purposes to remove suspended matter in the water to obtain water with lower turbidity. During the long-term use of the filter tank, dirt and even moss will remain on the wall of the water collection tank. After a long time, the microorganisms in the debris will multiply in large numbers, affecting the efficiency and service life of the water collection tank. At present, manual methods are mostly used to clean the inner wall of the water collection tank. The cleaning efficiency is relatively low and cleaning is also difficult. Cleaning personnel need to go down to the pool to work, which poses certain safety hazards. In addition, manual cleaning may not be timely. If the water collection tank is not cleaned in time, it will bring a great burden to the filter tank, generate more wastewater, and waste production resources.

[0003] Due to the above shortcomings of manual cleaning, some studies have proposed automatic cleaning devices for water collection tanks. For example, the Chinese patent with application number 2019102726237 discloses a cleaning device for a water collection tank in a sedimentation tank, which includes a frame, a power mechanism, a vertical roller brush mechanism and an inclined roller brush mechanism. The power mechanism, the vertical roller brush mechanism and the inclined roller brush mechanism are all installed on the frame. The power mechanism is used to drive the frame to move on the top of the water collection tank. The vertical roller brush mechanism is located at the bottom of the frame. The vertical roller brush mechanism is used to clean the inner wall of the water collection tank. The vertical roller brush mechanism is located in the water collection tank, and the inclined roller brush mechanism is used to clean the outer wall of the water collection tank. By setting a walking mechanism to drive the entire device to move to clean the inner and outer walls of the H-trough, the water collection tank is cleaned more comprehensively, reducing the impact of dirt on the filtration efficiency and service life of the water collection tank; at the same time, the walking mechanism is used for automatic cleaning, without manual cleaning, and the cleaning efficiency is higher. Reciprocating cleaning can be performed in a short time, and the cleaning effect is better.

[0004] However, the device can only clean one water collection tank at a time, while in fact there are several or even dozens of water collection tanks in the entire filter tank. If the device is used to clean the water collection tanks, it will take a lot of time to clean all the water collection tanks, which may easily delay the normal production operations of the water plant.

DETAILED DESCRIPTION

[0050] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0051] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the utility model described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, device, product or equipment that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0052] In one embodiment of the present invention, a water collection tank cleaning device is provided, which can simultaneously clean the inside and outside of the side walls of multiple water collection tanks 6 arranged in the filter tank 7. Figures 1 to 5The water collection tank cleaning device includes a walking mechanism 1, a lifting mechanism 2, a cleaning mechanism 3 and a driving mechanism 4.

[0053] The travel mechanism 1 includes a trolley 11, which is configured to travel back and forth along the extension direction of the water collection tank 8. Specifically, tracks 12 are respectively provided on both sides of the filter tank 7, the trolley 11 spans the filter tank 7 and rollers are provided at both ends of the trolley 11, and the trolley 11 can travel back and forth along the tracks 12 under the drive of a driving mechanism.

[0054] The lifting mechanism 2 is disposed on the traveling vehicle 11, and the lifting mechanism 2 is connected to the cleaning mechanism 3, and the lifting mechanism 2 is configured to drive the cleaning mechanism 3 to rise or fall. Figure 1 and Figure 2 As shown, a second support frame 15 is provided below the traveling vehicle 11, and the lifting mechanism 2 is provided on the second support frame 15. The cleaning mechanism 3 includes a first support frame 31, and the first support frame 31 is connected to the lifting mechanism 2.

[0055] See also Figures 1 to 3 The lifting mechanism 2 includes a driving assembly, a screw rod 25 and a nut 26. The nut 26 is arranged on the second support frame 15 and is rotatably connected to the second support frame 15. The screw rod 25 is vertically arranged and threadedly connected to the nut 26. The driving assembly is configured to drive the screw rod 25 to rotate. The lower end of the screw rod 25 is fixedly connected to the first support frame 31. Since the nut 26 can only rotate relative to the second support frame 15 fixed on the trolley 11, when the nut 26 rotates, the screw rod 25 moves in the vertical direction relative to the trolley 11, thereby driving the cleaning mechanism 3 to rise or fall.

[0056] like Figure 3 As shown, the driving assembly includes a first motor 21, a reducer 22, a third bevel gear 23 and a fourth bevel gear 24 which are sequentially connected in transmission. The output end of the first motor 21 is connected in transmission with the input end of the reducer 22, and the output shaft of the reducer 22 is arranged horizontally and fixedly connected with the third bevel gear 23. The third bevel gear 23 is meshedly connected with the fourth bevel gear 24. The fourth bevel gear 24 is sleeved on the outside of the nut 26 and fixedly connected with the nut 26.

[0057] In one embodiment of the utility model, in order to ensure that the cleaning mechanism 3 is lifted and lowered smoothly and stably, the water collection tank cleaning device further includes a guide device, the guide device includes a plurality of guide columns 13 arranged in the vertical direction and guide cylinders 14 corresponding to the guide columns 13 one by one, and the guide cylinders 14 are fixedly connected to the traveling crane 11. Figures 1 to 3 As shown, the guide cylinder 14 passes through the second support frame 15 and is fixedly connected to the second support frame 15, and the guide column 13 is fixedly connected to the first support frame 31; one guide column 13 passes through one guide cylinder 14. During the lifting process of the cleaning mechanism 3, the guide column 13 slides in the guide cylinder 14.

[0058] In one embodiment of the present utility model, the water collection tank cleaning device further includes a limit assembly 6. Figures 1 to 3 The limit assembly includes a first limit plate 61, a second limit plate 62, a first limit switch 63 and a second limit switch 64.

[0059] In this embodiment, the first limit plate 61 includes a first plate 611 and a second plate 612 arranged opposite to each other in the vertical direction, and the first plate 611 and the second plate 612 are connected by a third plate 613, that is, the first limit plate 61 is a horizontally arranged U-shaped structure. The first plate 611 is fixedly connected to the side of the second support frame 15. The first limit switch 63 is arranged on the side of the first plate 611 facing the second plate 612, and the second limit switch 6 is arranged on the side of the second plate 612 facing the first plate 611.

[0060] The first limit switch 63 and the second limit switch 64 are both electrically connected to the first motor 21 in the lifting mechanism (2). When either the first limit switch 63 or the second limit switch 64 is triggered, the first motor 21 stops working.

[0061] The second limit plate 62 is L-shaped, one end of which is fixedly connected to the first support frame 31, and the other end of the second limit plate 62 extends between the first limit switch 63 and the second limit switch 64, and can be abutted against one of the first limit switch 63 and the second limit switch 64. When the lifting mechanism 2 drives the first support frame 31 to rise, when the second limit plate 62 abuts against the first limit switch 63, so that the first limit switch 63 is triggered, the first motor 21 stops working, and the first support frame 31 stops rising. At this time, the lowermost end of the cleaning mechanism 3 is located above the water collection tank 8; when the lifting mechanism 2 drives the first support frame 31 to descend, when the second limit plate 62 abuts against the second limit switch 64, so that the second limit switch 64 is triggered, the first motor 21 stops working, and the first support frame 31 stops descending. At this time, the cleaning part of the cleaning mechanism 3 is fully in contact with the side wall of the water collection tank 8, and the cleaning operation can be performed. It should be noted that the first limit switch 63 may also be disposed above the upper end of the second limit plate 62 .

[0062] The utility model can control the rising or falling of the sump cleaning device as needed through the lifting mechanism and the limit assembly, and can stop the rising operation in time through the first limit switch after the cleaning brush at the lower end of the cleaning device rises above the sump, and can stop the descending operation in time through the second limit switch after the cleaning brush at the lower end of the cleaning device descends to fully contact the sump, so as to avoid damage to the equipment or the cleaning brush due to misoperation. For example, if there is no second limit switch, the cleaning brush may be damaged due to the pressure against the bottom of the filter tank due to the failure to stop the lifting mechanism in time during the descent process.

[0063] See also Figure 1 , Figure 2 and Figure 5 , the cleaning mechanism 3 is arranged below the traveling vehicle 11, and the cleaning mechanism 3 also includes a first rotating shaft 32 and a plurality of cleaning components 5, wherein the first supporting frame 31 is connected to the lifting mechanism 2; the first rotating shaft 32 spans across a plurality of water collecting tanks 8 and is rotatably connected to the first supporting frame 31, and the first rotating shaft 32 is connected to the driving mechanism 4, and the driving mechanism 4 is configured to drive the first rotating shaft 32 to rotate. The driving mechanism 4 includes a second motor 41, and the output shaft of the second motor 41 is connected to the first rotating shaft 32 in a transmission connection. Specifically, the output shaft of the second motor 41 may be colinear with the axis center line of the first rotating shaft 32, and the two may be directly connected through a coupling, or the output shaft of the second motor 41 may be connected to a gear arranged on the first rotating shaft 32 through one or more gears, and the first rotating shaft 32 may be driven to rotate through gear transmission.

[0064] like Figure 5 As shown, a plurality of the cleaning assemblies 5 are arranged below the first support frame 31, and a plurality of third support frames 35 are arranged below the first support frame 31, and the third support frames 35 are configured to carry the cleaning assemblies 5. The plurality of cleaning assemblies 5 are arranged one by one with the plurality of water collecting tanks 8, and the cleaning assemblies 5 include a gear assembly and a cleaning brush 56 connected to the output end of the gear assembly, and the cleaning brush 56 is contactably connected to the side wall of the water collecting tank 8; the input end of the gear assembly is meshedly connected with the second bevel gear 34 arranged on the first rotating shaft 32 through the first bevel gear 33.

[0065] In this embodiment, the gear assembly includes an input shaft 51, a first T-type gear box 52 and a second T-type gear box 53. The input shaft 51 is configured as the input end of the gear assembly, one end of the input shaft 51 is fixedly connected to the first bevel gear 33, and the other end of the input shaft 51 is connected to the input shaft of the first T-type gear box 52. The input shaft of the first T-type gear box 52 is vertically arranged, and the two output shafts are horizontally arranged, and the output shaft of the first T-type gear box 52 is transmission-connected with the second T-type gear box 53. The input shaft of the second T-type gear box 53 is horizontally arranged, and its output shaft is vertically arranged, and the output shaft of the second T-type gear box 53 is connected to the cleaning brush 56.

[0066] The first T-type gearbox 52 and the second T-type gearbox 53 are T-type gearboxes commonly used in the art. Figure 6 , the first T-type gearbox 52 includes a T-type gearbox input shaft 521, a fifth bevel gear 522, two sixth bevel gears 523 and two T-type gearbox output shafts 524, the fifth bevel gear 522 is fixedly sleeved on the T-type gearbox input shaft 521, the fifth bevel gear 522 is meshedly connected with the sixth bevel gears 523 arranged on both sides thereof, and the sixth bevel gear 523 is fixedly sleeved on the T-type gearbox output shaft 524. The T-type gearbox input shaft 521 is fixedly connected to the input shaft 51, thereby realizing that the rotation of the input shaft 51 around the vertical direction can be converted into the rotation of the T-type gearbox output shaft 524 around the horizontal direction. The input end of the T-type gearbox input shaft and the output end of the T-type gearbox output shaft 524 are both provided with splines. By providing a T-type gearbox, it is possible to facilitate the transmission and change of direction of force, and the forward and reverse rotation of the spline shaft does not affect the transmission.

[0067] In this embodiment, see Figure 1 The water collection tank 8 disposed in the middle of the filter tank 7 has two side walls. Some filter tanks also have the water collection tank 8 disposed on their sides, and the water collection tank 8 has only one side wall. Cleaning brushes 56 are disposed on both the inner and outer sides of each side wall of the water collection tank 8, such as Figure 1 That is, if the water collecting tank 8 has one side wall, the two output shafts of the first T-type gear box 52 are respectively connected to one of the second T-type gear boxes 53. If the water collecting tank 8 has only one side wall, one of the two output shafts of the first T-type gear box 52 is connected to one of the second T-type gear boxes 53.

[0068] The output shaft of each second T-shaped gear box 53 is used to drive the two cleaning brushes 56 to rotate. Each cleaning brush 56 extends in a vertical direction and can rotate around the vertical direction under the drive of the output shaft of the second T-shaped gear box 53, thereby cleaning the sump 8.

[0069] The utility model drives the first rotating shaft 32 to rotate by a second motor 41, and converts the rotation of the first rotating shaft 32 in the horizontal plane into the rotation of the cleaning brush 56 in the vertical plane through the combination of multiple first T-type gear boxes 52 and second T-type gear boxes 53, that is, multiple groups of cleaning components can work simultaneously through one power source, which not only saves equipment space and device costs but also is more energy-efficient.

[0070] There are many ways to drive the two cleaning brushes 56 to rotate through the output shaft of the second T-type gear box 53 .

[0071] One way is Figure 5 As shown, the cleaning assembly 5 also includes two first gears 54 and a second gear 55. The output shaft of the second T-type gearbox 53 is meshed and connected with one of the first gears 54 and drives the first gear 54 to rotate. The cleaning brush 56 is fixedly connected with the first gear 54 through a shaft, thereby realizing that the output shaft of the second T-type gearbox 53 drives the cleaning brush 56 to rotate and clean the side wall of the water collection tank 8; the first gear 54 is meshed and connected with the second gear 55, and the second gear 55 is connected with another first gear 54, thereby the first first gear 54 drives the second gear 55 to rotate, and the second gear 55 drives the second first gear 54 to rotate, and the second first gear 54 is also fixedly connected with one of the cleaning brushes 56 through a shaft, thereby realizing that the output shaft of the second T-type gearbox 53 drives the two cleaning brushes 56 to rotate to clean the inside and outside of one side wall of the water collection tank 8.

[0072] Another method is that the two cleaning brushes are respectively connected to one of the first gears 54, and the two first gears 54 are meshed with the second gear 55. The difference between this method and the previous method is that the output shaft of the second T-type gear box 53 is meshed with the second gear 55 to drive the second gear 55 to rotate. The second gear 55 drives the first gears 54 on both sides, thereby driving the cleaning brushes 56 to rotate to clean the inside and outside of a side wall of the water collection tank 8.

[0073] The utility model is provided with a walking mechanism, a lifting mechanism, a driving mechanism and a cleaning mechanism. The cleaning mechanism includes a plurality of cleaning components. Each cleaning component can clean the inside and outside of two side walls of a water collection tank. A driving mechanism drives the plurality of cleaning components to clean synchronously, and the cleaning process of all the water collection tanks in the filter tank can be completed at one time. The cleaning efficiency is higher and it is more convenient and quick.

[0074] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0075] The above is only a specific implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
