Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a cleaning device and cleaning equipment having the same. Background Art

[0002] Many machines and equipment used outdoors, exposed to the elements year-round, accumulate large amounts of dust, bird droppings, and other dirt on their surfaces. This is not only unsightly but also easily affects the equipment's efficiency and shortens its lifespan. Therefore, these surfaces require regular cleaning. Among the many cleaning methods, using cleaning robots to clean the surfaces of equipment is a widely used method. Currently, cleaning robots are commonly used to clean surfaces such as photovoltaic panels. The cleaning mechanism, a core component of a cleaning robot, typically includes a brush, a water sprayer, and possibly a vacuum or blower. The brush is often designed with a soft material to avoid scratching the panel surface. It physically removes dust and dirt from the panel through rotation or vibration. The water sprayer is used to spray an appropriate amount of water or detergent to help dissolve and flush away stubborn stains.

[0003] However, when cleaning robots clean photovoltaic panels, wastewater flows down the panels. Due to the height difference between the panel's bottom frame and the panel itself, wastewater remains at the bottom of the panels after cleaning. After evaporation, dirt and other contaminants in this residual wastewater re-adhere to the panels, obstructing the bottom area and affecting the panels' effective photoelectric conversion area and energy conversion efficiency. Utility Model Content

[0004] In view of this, the utility model provides a cleaning device and a cleaning equipment having the same, so as to solve the problem that sewage remains after the photovoltaic panel cleaning robot cleans the photovoltaic panel.

[0005] In a first aspect, the present invention provides a cleaning device comprising:

[0006] Support members;

[0007] The scraper assembly includes a scraper shaft and a scraper body, wherein the scraper shaft is rotatably mounted on the support member, the scraper body is fixedly connected to the scraper shaft, and the scraper body is parallel to the scraper shaft and extends radially toward the scraper shaft;

[0008] The dirt recovery assembly is installed on the support member. A recovery groove is provided on the dirt recovery assembly. The recovery groove is arranged parallel to the scraper assembly. A recovery part is provided on the side of the recovery groove facing the scraper assembly. The side of the recovery part facing the scraper assembly is adapted to the movement path of the end of the scraper body.

[0009] When using a cleaning device to clean a photovoltaic panel, the scraper shaft is driven to rotate by an external driving mechanism, wherein the driving mechanism can be fixedly mounted on a support member or externally mounted on the cleaning device. During the rotation of the scraper shaft, the scraper body is driven to rotate toward the recovery portion to scrape off dust, dirt, sewage, etc. on the photovoltaic panel. Since the side of the recovery portion facing the scraper assembly is adapted to the movement path of the end of the scraper body, the end of the scraper body can contact and abut the recovery portion, or a small gap is reserved between the end of the scraper body and the recovery portion to ensure the smooth rotation of the scraper body when passing through the recovery portion. When the scraper body drives the dust, dirt, and sewage to move to the recovery portion, the dust, dirt, and sewage can move to the recovery portion and eventually fall into the recovery tank. The recovery tank is used to recover the sewage generated during the cleaning process, thereby achieving the effect of recycling the sewage and dirt washed off during the photovoltaic panel cleaning process, preventing sewage and dirt from remaining on the photovoltaic panel, and also preventing sewage from flowing into other areas of the photovoltaic panel and affecting the cleaning effect. At the same time, by recycling sewage, it can also prevent sewage from polluting the environment around the photovoltaic panel installation area.

[0010] In an optional embodiment, the dirt recovery assembly further includes a spiral recovery member rotatably mounted on the support member, and the spiral recovery member is disposed in the recovery tank.

[0011] By setting a spiral recovery element, the sewage or dirt collected in the recovery tank can be directionally recovered, so that the sewage can flow directionally to one end of the recovery tank, or the spiral direction on the spiral recovery element can be alternately set clockwise and counterclockwise along the axial direction of the spiral recovery element, so that the sewage can be directionally recovered to a designated position in the middle of the recovery tank.

[0012] In an optional embodiment, the dirt recovery assembly further includes a sewage driving member, one end of the sewage driving member is connected to the recovery tank, and the other end is connected to the sewage storage member.

[0013] The wastewater storage unit can be mounted externally on the cleaning device or fixed to a support as part of the cleaning device. The wastewater drive unit drives the wastewater in the recovery tank to flow into the wastewater storage unit, where it is stored. This prevents wastewater from accumulating in the recovery tank and causing overflow, thereby extending the continuous operation time of the cleaning device.

[0014] In an optional embodiment, a torque transfer ring is sleeved on the scraper shaft, a snap-fitting tooth is provided on the torque transfer ring, and the scraper body is fixedly installed in the snap-fitting tooth.

[0015] In an optional embodiment, a pair of scraper clamps are fixedly installed in the engaging teeth, and the scraper body is fixedly clamped and installed between the pair of scraper clamps.

[0016] In an optional embodiment, fixed turntables are mounted on both ends of the scraper shaft, a clearance groove is provided on the fixed turntable, both ends of the scraper clamp extend into the clearance groove, and the scraper clamp is fixedly connected to the clearance groove.

[0017] In an optional embodiment, a spray assembly is further included, mounted on the support member, the spray assembly being located at the front end of the support member and / or facing the scraper assembly. By installing the spray assembly on the cleaning device, the spray assembly located at the front end of the support member sprays cleaning fluid onto the surface of the photovoltaic panel, thereby reducing the adhesion of debris to the photovoltaic panel, allowing the debris to be easily removed by the scraper body. The spray assembly located toward the scraper assembly continuously sprays cleaning fluid onto the scraper body, continuously cleaning the wastewater and stains on the scraper body.

[0018] In an optional embodiment, a cleaning liquid storage component is further included, a liquid supply pipeline is connected between the spray assembly and the cleaning liquid storage component, and a cleaning liquid driving component is installed on the liquid supply pipeline.

[0019] In an optional embodiment, it also includes a roller brush assembly, which is rotatably mounted on the front end of the support member.

[0020] By setting up a roller brush assembly and using it to clean the dust and large debris on the photovoltaic panel in advance, most of the adhesive attachments can be cleaned away, reducing the difficulty of cleaning the subsequent scraper assembly and improving the cleaning effect.

[0021] In a second aspect, the present invention further provides a cleaning device having the cleaning device of the present invention, wherein a hand-held rod is rotatably mounted on the cleaning device or the cleaning device is mounted on a walking mechanism. Since the cleaning device includes the cleaning device and has the same effect as the cleaning device, no further details will be given here. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, 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 embodiments described 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 those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0034] The following combination Figures 1 to 7 , describing the embodiments of the present utility model.

[0035] According to an embodiment of the present invention, a cleaning device is provided. Depending on the size, the cleaning device can be installed on a photovoltaic panel cleaning robot, a household cleaning robot, a medium-sized cleaning device for shopping malls, or a road sweeper, and used as the cleaning component thereof. This embodiment uses a photovoltaic panel cleaning robot as an example. The operation of the cleaning device in other cleaning devices is the same as described in this embodiment.

[0036] The cleaning device comprises a support member 1 for mounting various components of the cleaning device, a scraper assembly 2 and a dirt recovery assembly 3. The support member 1 may be a support frame or a support shell.

[0037] The scraper assembly 2 includes a scraper shaft 201 and a scraper body 202. The scraper shaft 201 is rotatably mounted on the support 1. A plurality of scraper bodies 202 are arranged at intervals in the circumferential direction of the scraper shaft 201. The scraper bodies 202 are fixedly connected to the scraper shaft 201, and the scraper bodies 202 are parallel to the scraper shaft 201. The scraper bodies 202 extend radially toward the scraper shaft 201; the dirt recovery assembly 3 is mounted on the support 1, and a recovery groove 301 is provided on the dirt recovery assembly 3. The recovery groove 301 is arranged parallel to the scraper assembly 2, and a plate-shaped recovery portion 302 is provided on the side of the recovery groove 301 facing the scraper assembly 2. The side of the recovery portion 302 facing the scraper assembly 2 is adapted to the movement path of the scraper body 202 away from one end of the scraper shaft.

[0038] The support member 1 in this embodiment is a support shell, and the mounting positions of various components are set inside the support shell. In order to facilitate the movement of the cleaning device on the photovoltaic panel, a running wheel is installed at the bottom of the support shell. During the movement of the cleaning device, the running wheel and the bottom of the recovery part 302 are supported on the photovoltaic panel. In order to avoid direct interference between the recovery part 302 and the photovoltaic panel or the scraper body 202, the scraper body 202 is made of a flexible structure such as sponge or rubber. The main body of the recovery part 302 is a rigid structure. The bottom of the recovery part 302 can be set to an arc-shaped soft rubber bead 303, so that the soft rubber bead 303 is in contact with the photovoltaic panel and fits well. This can not only make the soft rubber bead 303 fit tightly with the photovoltaic panel to prevent dirt from being missed, but also avoid scratching the photovoltaic panel when the cleaning device moves. When the scraper body 202 rotates to the surface of the recovery part 302 and the soft rubber bead 303, it will be squeezed and deformed to improve the dirt collection effect and ensure that dirt will not leak out. In this embodiment, the dirt recovery assembly 3 is arranged at the front end of the scraper assembly 2 . In some other embodiments, the scraper assembly 2 can also be arranged at the rear end of the dirt recovery assembly 3 .

[0039] When the photovoltaic panel is cleaned using the cleaning device, the scraper shaft 201 is driven to rotate by an external driving mechanism, wherein the driving mechanism can be fixedly mounted on the support 1 or externally mounted on the cleaning device. During the rotation of the scraper shaft 201, the scraper body 202 is driven to rotate toward the recovery portion 302 to scrape the dust, dirt, sewage, etc. on the photovoltaic panel. Since the side of the recovery portion 302 facing the scraper assembly 2 is adapted to the movement path of the end of the scraper body 202, the end of the scraper body 202 can contact and abut the recovery portion 302, or a small gap can be reserved between the end of the scraper body 202 and the recovery portion 302 to ensure the smoothness of the rotation of the scraper body 202 when passing through the recovery portion 302. When the scraper body 202 drives the dust, dirt, and sewage to the recovery section 302, the dust, dirt, and sewage can move to the recovery section 302 and eventually fall into the recovery tank 301. The recovery tank 301 is used to recycle the sewage generated during the cleaning process, thereby achieving the effect of recycling the sewage and dirt washed off during the photovoltaic panel cleaning process, preventing the sewage and dirt from remaining on the photovoltaic panel, and also preventing the sewage from flowing into other areas of the photovoltaic panel and affecting the cleaning effect. At the same time, the sewage after cleaning the photovoltaic panel will contain dust particles, detergent residues, microorganisms, and other chemicals that may be peeled off from the surface of the photovoltaic panel, which can be a variety of pollutants. Photovoltaic panels are usually installed on lawns or fish ponds with relatively weak ecology. If the sewage after the photovoltaic panel is cleaned is discharged directly without treatment, this sewage may penetrate into the soil or be discharged into the fish pond, which will change the normal ecology of the plants on the lawn or the organisms in the fish pond, affecting the normal growth of organisms in the environment. In addition, sewage may also form stagnant water on the surface, becoming a breeding ground for mosquitoes, further exacerbating public health problems. By recycling sewage, it can also prevent sewage from polluting the environment around the photovoltaic panel installation area.

[0040] In this embodiment, the driving mechanism as a part of the cleaning device is fixedly mounted on the support member 1 , and the output end of the driving motor 204 serving as the driving mechanism is drivingly connected to the scraper shaft 201 .

[0041] In one embodiment, the dirt recovery assembly 3 further includes a spiral recovery member 304, which is rotatably mounted on the support member 1 and is disposed in the recovery tank 301. The spiral recovery member 304 can be a spiral scraper with a rotating shaft or a spiral brush with a rotating shaft. In this embodiment, the spiral recovery member 304 is a spiral scraper.

[0042] By setting a spiral recovery element 304, the sewage or dirt collected in the recovery tank 301 is directed to be gathered, so that the sewage can flow to one end of the recovery tank 301 in a directed manner, or the spiral direction on the spiral recovery element 304 can be alternately set clockwise and counterclockwise along the axial direction of the spiral recovery element 304, so that the sewage is directed to be gathered at a designated position in the middle of the recovery tank 301.

[0043] The end of the scraper shaft 201 away from the drive motor 204 extends outside the support member 1, and a first transmission gear 203 is provided on the scraper shaft 201 extending outside the support member 1. The same end of the spiral recovery member 304's shaft also extends outside the support member 1, and a second transmission gear 305 is provided on the end of the spiral recovery member 304's shaft extending outside the support member 1. A transmission chain 306 is connected to the first transmission gear 203 and the second transmission gear 305. The transmission belt engages with the two transmission chains 306, so that when the drive motor 204 drives the scraper shaft 201 to rotate, it can also drive the spiral recovery member 304 to rotate. In some other embodiments, the spiral recovery member 304 and the scraper shaft 201 can also be driven by a pair of gears, or by a pair of transmission wheels using a transmission belt to tighten the transmission, or the spiral recovery member 304 is connected to the output shaft of another separate drive motor 204, so that the spiral recovery member 304 and the scraper assembly 2 are driven by two different drive motors 204.

[0044] In one embodiment, the dirt recovery assembly 3 further includes a sewage drive 307. One end of the sewage pump serving as the sewage drive 307 is connected to the recovery tank 301 via a sewage pipeline, and the other end is connected to a sewage storage unit 308 via sewage. The sewage storage unit can be a structure capable of accommodating fluid, such as a box, tank, or bottle. In this embodiment, the sewage storage unit is a sewage storage tank. The connection point between the sewage pipeline and the recovery tank 301 corresponds to the position where the spiral recovery unit 304 collects sewage within the recovery tank 301. In this embodiment, the spiral direction of the spiral recovery unit 304 is the same, that is, the sewage pipeline is connected to the bottom of one side of the recovery tank 301.

[0045] In this embodiment, the wastewater storage unit 308, as part of the cleaning device, is fixedly mounted on the support member 1. The wastewater driving unit 307 drives the wastewater in the recovery tank 301 to flow into the wastewater storage unit 308, where it is stored. This prevents wastewater from accumulating in the recovery tank 301 and causing overflow, thereby extending the operating time of the cleaning device. In some other embodiments, the wastewater storage unit 308 can also be mounted externally to the cleaning device.

[0046] In one embodiment, a torque transfer ring 205 is sleeved on the scraper shaft 201, and a snap-fitting tooth 206 is provided on the torque transfer ring 205. The scraper body 202 is fixedly mounted within the snap-fitting tooth 206. By clamping the scraper body 202 within the snap-fitting tooth 206, the stability of the connection between the scraper body 202 and the scraper shaft 201 is improved.

[0047] Furthermore, a pair of scraper clamps 207 are fixedly mounted within the engaging teeth 206, and the scraper body 202 is fixedly mounted between the pair of scraper clamps 207. The long scraper clamps 207 secure the scraper body 202 within the engaging teeth 206, thereby improving the stability of the scraper body 202 and preventing damage to the scraper body 202 due to localized force concentration when the scraper body 202 rotates.

[0048] In one embodiment, fixed discs 208 are sleeved on both ends of the scraper shaft 201. The fixed discs 208 are provided with clearance grooves 209. Both ends of the scraper clamping plate 207 extend into the clearance grooves 209, and the scraper clamping plate 207 is fixedly connected to the clearance grooves 209. By fixing both ends of the scraper clamping plate 207 into the clearance grooves 209, the scraper clamping plate 207 is limited in position, thereby improving the stability of the scraper clamping plate 207.

[0049] In one embodiment, the cleaning device further includes two groups of spray assemblies 4 mounted on the support member 1, each group of spray assemblies 4 being provided with multiple spray heads 401 at intervals. One group of spray assemblies 4 is provided at the front end of the support member 1, and the other group of spray assemblies 4 is provided toward the scraper assembly 2. By installing the spray assemblies 4 on the cleaning device, the spray assemblies 4 located at the front end of the support member 1 spray cleaning fluid onto the surface of the photovoltaic panel, thereby reducing the adhesion of attached matter to the photovoltaic panel, allowing the attached matter to be easily removed by the scraper body 202; the spray assemblies 4 located toward the scraper assembly 2 continuously spray cleaning fluid onto the scraper body 202, continuously cleaning the dirty water and stains on the scraper body 202. In some other embodiments, only one of the two groups of spray assemblies 4 may be provided.

[0050] Furthermore, a cleaning liquid storage component 402 is fixedly mounted on the support member 1, and a liquid supply pipeline is connected between the spray assembly 4 and the cleaning liquid storage component 402, and a water pump serving as a cleaning liquid driving component 403 is installed on the liquid supply pipeline. The cleaning liquid storage component 402 can be a structure such as a box, a tank, or a bottle that can accommodate cleaning liquid, wherein the cleaning liquid can be clean water, or an aqueous solution containing cleaning liquid. In this embodiment, a water tank is used as the cleaning liquid storage component 402. Cleaning liquid is provided to the two groups of spray assemblies 4 through the water tank, reducing the pipeline connection between the cleaning device and the external equipment, so that the cleaning device can be moved arbitrarily on the photovoltaic panel. In some other embodiments, the cleaning liquid storage component 402 can also be an external device separated from the cleaning device, and connected to the spray head 401 through a liquid supply pipeline. Alternatively, the cleaning liquid storage component 402 can also be fixedly mounted at any other position of the cleaning equipment.

[0051] In one embodiment, a roller brush assembly 5 is further included, which is rotatably mounted on the front end of the support member 1. A roller brush power motor 6 is mounted on one side of the roller brush assembly 5, and the roller brush power motor 6 drives the roller brush assembly 5 to rotate.

[0052] By setting up the roller brush assembly 5 and using the roller brush assembly 5 to clean the dust and large debris on the photovoltaic panel in advance, most of the adhesive attachments can be cleaned away, reducing the difficulty of cleaning the subsequent scraper assembly 2 and improving the cleaning effect.

[0053] According to an embodiment of the present invention, on the other hand, a cleaning device is provided, which has the cleaning device provided in this embodiment, and a handheld rod 7 is rotatably mounted on the cleaning device for use as a household cleaning robot, such as Figure 8 Alternatively, the cleaning device can be installed on a traveling mechanism such as an AGV or large-scale sweeper to serve as a photovoltaic panel cleaning robot, a medium-sized cleaning device for use in shopping malls or workshops, or a road sweeper. Because the cleaning equipment includes the cleaning device and has the same effects as the cleaning device, its further description is omitted.

[0054] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations shall fall within the scope defined by the appended claims.
