Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel cleaning, and particularly relates to a cleaning mop. Background Technique

[0002] A photovoltaic panel assembly is a power generation device that generates direct current when exposed to sunlight. It consists of thin-film solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon). After a long time, there will be dust or other deposits on the surface of the photovoltaic panel assembly, which affects the light conversion rate.

[0003] The utility model patent with the patent authorization announcement number CN 216026401 U discloses a novel cleaning mop, which includes a flat plate. A wrap-around edge is provided at the edge of the flat plate. A protrusion is provided inside the wrap-around edge. An elastic body is provided below the flat plate. The protrusion is in contact connection with the edge of the elastic body. A scouring pad is provided below the elastic body. A water storage tank is provided above the flat plate. A universal shaft connector is provided above the water storage tank. The other end of the universal shaft connector is provided with a shock-absorbing cylinder. The other end of the shock-absorbing cylinder is provided with a mop rod. The structure is simple, the operation is convenient, the cleaning strength is strong, and the work efficiency is improved.

[0004] However, there are still some drawbacks when the above device is actually used. The more obvious one is that during long-distance cleaning, since the mop rod is mostly made of stainless steel, under the influence of long distance, the front end and the rear end of the mop will tilt upwards. Different operators have different strengths and cleaning methods, and the pressures on the mop rod are also inconsistent, which may cause the rod body to deform too much, resulting in the problem of hidden cracks in the rod body.

[0005] Therefore, it is very necessary to invent a cleaning mop to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a cleaning mop. By setting a support component, when the annular sleeve at the top of the multi-section telescopic rod is driven to move downward in the chute by stretching, the lower support rod connected at this time will move inward and contract, so the distance between the two double-rotating wash heads is reduced. Under the limited length of the multi-section telescopic rod, a triangular structure is formed between the upper support rod and the lower support rod. Therefore, no matter how long the multi-section telescopic rod extends, it will always be supported by the upper support rod and pulled by the lower support rod. The stretching distance of the multi-section telescopic rod can control the working range between the two double-rotating wash heads. It can not only protect and support the mop rod, but also expand the cleaning area of the double-rotating wash heads for the photovoltaic panel assembly, and the operation is relatively simple, and it can quickly perform daily cleaning and maintenance on the photovoltaic panel to solve the problem that different operators have different strengths and cleaning methods, and the pressures on the mop rod are also inconsistent, which may cause the rod body to deform too much, resulting in the problem of hidden cracks in the rod body as mentioned in the above background technique.

[0007] According to one aspect of the present disclosure, the following technical solution is provided: a cleaning mop, including a mop rod, and a plurality of telescopic rods are movably and penetratingly connected to the inner arc surface of the mop rod, and a limiting component is movably sleeved at the bottom end of the outer arc surface of the mop rod;

[0008] The limiting component includes a fixing sleeve threadedly connected to the outer arc surface of the mop rod. A positioning shaft is provided at the edge of one side of the outer arc surface of the fixing sleeve. A dial plate is movably connected to the inner side wall of the positioning shaft through a rotating shaft. A pressing surface is provided on the side of the dial plate facing the fixing sleeve. A locking plate is movably connected to the side of the fixing sleeve away from the dial plate through a positioning shaft. An arched portion is provided on the upper surface of the locking plate, and the arched portion is movably lapped with the pressing surface under the dial plate. A limiting boss is provided at the front end of one side of the locking plate. A rectangular groove is formed in the middle of the outer arc surface of the fixing sleeve. One end of the limiting boss penetrates into the rectangular groove. Torsion springs are connected to the bearings on both sides of the dial plate. A return spring is lapped at the rear end of one side of the locking plate, and one end of the return spring is fixedly installed on the fixing sleeve. A limiting hole is provided on one side of the outer arc surface of the plurality of telescopic rods.

[0009] In a cleaning mop according to at least one embodiment of the present disclosure, the inner arc surface of the limiting hole is lapped and adapted to the limiting boss on one side of the locking plate. An extrusion surface is provided on the side of the locking plate away from the arched portion, and one side of the extrusion surface abuts against the surface of the plurality of telescopic rods.

[0010] In a cleaning mop according to at least one embodiment of the present disclosure, a support component is movably connected to the surface of the positioning shaft through a rotating shaft. The support component includes a connecting seat movably connected to the surface of the positioning shaft. A vertical plate is fixedly installed on the inner top wall of the connecting seat. A locking tooth is provided on one side of the vertical plate.

[0011] In a cleaning mop according to at least one embodiment of the present disclosure, an upper support rod is movably connected to the side of the connecting seat close to the vertical plate through a rotating shaft. A chute is formed on the upper surface of the upper support rod. Lower support rods are slidably clamped on both the upper and lower surfaces of the upper support rod. A fixing pin is movably connected to one side of the upper surface of the lower support rod.

[0012] In a cleaning mop according to at least one embodiment of the present disclosure, the outer arc surface of the fixing pin is slidably clamped into the chute. An annular sleeve is fixedly installed on the side of the lower support rod away from the fixing pin. The annular sleeve is slidably sleeved on the plurality of telescopic rods. A hinge seat is movably connected to the node of the upper support rod and the connecting seat.

[0013] In a cleaning mop according to at least one embodiment of the present disclosure, a tooth groove is formed on one side of the outer arc surface of the hinge seat, and the tooth groove is movably clamped with the locking tooth. A double-rotating washing head is fixedly installed at one end of the lower support rod.

[0014] Technical effects and advantages of the present utility model:

[0015] 1. By pulling the annular sleeve at the top of the telescopic multi-section rod to drive the lower support rod to move downward in the chute, the movement of the lower support rod at this time will cause the connected upper support rod to close and contract inward. Therefore, the distance between the two double-rotating washing heads is close. A triangular structure is formed between the upper support rod and the lower support rod within the limited length of the multi-section telescopic rod. Therefore, no matter how long the multi-section telescopic rod extends, it will always be supported by the upper support rod and pulled by the lower support rod. The stretching distance of the multi-section telescopic rod can control the working range between the two double-rotating washing heads, which can not only protect and support the drag rod, but also increase the cleaning area of the photovoltaic module by the double-rotating washing heads, and the operation is relatively simple, and it can quickly perform daily cleaning and maintenance on the photovoltaic panel.

[0016] 2. By adjusting the limit component, the telescopic length of the drag rod can be freely adjusted, so as to adjust to a suitable position according to the distance of the photovoltaic module, and then clean in a simple and convenient way. Without the help of climbing equipment, the photovoltaic panel at a higher position can be easily cleaned. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] For descriptive purposes, the present disclosure may use spatial relative terms such as "under", "below", "beneath", "lower", "above", "on", "upper", and "side (e.g., as in "side wall")" to describe the relationship of one component to another (other) component as shown in the drawings. In addition to the orientation depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacturing. For example, if the device in the drawing is flipped, a component described as "under" or "beneath" another component or feature will then be positioned "above" the said other component or feature. Thus, the exemplary term "under" can encompass both the "above" and "below" orientations. In addition, the device may be otherwise positioned (e.g., rotated 90 degrees or at other orientations), and accordingly, the spatial relative descriptors used herein are to be interpreted accordingly.

[0031] As Figures 1 - 3As shown, a cleaning mop disclosed herein may include a mop rod 1, the inner arc surface of the mop rod 1 is movably connected to a multi-section telescopic rod 2, the bottom end of the outer arc surface of the mop rod 1 is movably sleeved with a limiting assembly 3, the limiting assembly 3 includes a fixing sleeve 31 threadedly connected to the outer arc surface of the mop rod 1, a positioning shaft 32 is provided at an edge of one side of the outer arc surface of the fixing sleeve 31, a dial plate 33 is movably connected to the inner side wall of the positioning shaft 32 through a rotating shaft, a pressing surface 34 is provided on the side of the dial plate 33 facing the fixing sleeve 31, a locking plate 35 is movably connected to the side of the fixing sleeve 31 away from the dial plate 33 through the positioning shaft 32, an arched portion 36 is provided on the upper surface of the locking plate 35, and the arched portion 36 is pressed against the bottom of the dial plate 33 The surfaces 34 are movably overlapped, a limiting boss 37 is provided at the front end of one side of the locking plate 35, a rectangular groove is opened in the middle of the outer arc surface of the fixing sleeve 31, one end of the limiting boss 37 passes through the rectangular groove, and the bearings on both sides of the shift plate 33 are connected with torsion springs 39, and a return spring 310 is overlapped at the rear end of one side of the locking plate 35, and one end of the return spring 310 is fixedly installed on the fixing sleeve 31, a limiting hole 4 is provided on one side of the outer arc surface of the multi-section telescopic rod 2, and the inner arc surface of the limiting hole 4 is overlapped and adapted with the limiting boss 37 on one side of the locking plate 35, and an extrusion surface 311 is provided on the side of the locking plate 35 away from the arched portion 36, and one side of the extrusion surface 311 abuts against the surface of the multi-section telescopic rod 2.

[0032] Therefore, in actual use, when the rotating dial plate 33 moves downward, the torsion spring 39 is stretched along the rotation direction, and the pressing surface 34 presses the locking plate 35 inward to tighten, so that the limiting boss 37 inside the locking plate 35 is respectively stuck or pressed in the limiting hole 4 on the side wall of the multi-section telescopic rod 2, and at the same time, the extrusion surface 311 at the bottom is pressed on the side wall of the multi-section telescopic rod 2, so that the multi-section telescopic rod 2 is fixed in the fixing sleeve 31 and cannot move.

[0033] When the rotating dial plate 33 moves in the opposite direction, the locking plate 35 returns to its original state due to the elasticity of the return spring 310, and the limiting bosses 37 inside the locking plate 35 are respectively separated from the limiting holes 4 on the side walls of the multi-section telescopic rod 2, so that the multi-section telescopic rod 2 can move back and forth in the mop rod 1.

[0034] Therefore, by adjusting the limit assembly 3, the telescopic length of the drag rod can be freely adjusted, so that it can be adjusted to a suitable position according to the distance of the photovoltaic component, and then cleaned in a simple and convenient way. Photovoltaic panels in higher positions can be easily cleaned without the aid of climbing equipment.

[0035] Figure 4 It is a schematic diagram of the overall structure of a support assembly 5 of a cleaning mop according to an embodiment of the present disclosure.

[0036] like Figure 4 andFigure 5 As shown, in the present disclosure, a support assembly 5 is movably connected to the surface of the positioning shaft 32 through a rotating shaft. The support assembly 5 includes a connecting seat 51 movably connected to the surface of the positioning shaft 32. A vertical plate 52 is fixedly installed on the inner top wall of the connecting seat 51. A locking tooth 53 is provided on one side of the vertical plate 52. A upper support rod 510 is movably connected to the side of the connecting seat 51 close to the vertical plate 52 through a rotating shaft. A chute 54 is formed on the upper surface of the upper support rod 510. Lower support rods 55 are slidably clamped on both the upper and lower surfaces of the upper support rod 510. A fixing pin 56 is movably connected to one side of the upper surface of the lower support rod 55. The outer arc surface of the fixing pin 56 is slidably clamped into the chute 54. A ring sleeve 57 is fixedly installed on the side of the lower support rod 55 away from the fixing pin 56. The ring sleeve 57 is slidably sleeved on the multi-joint telescopic rod 2. A hinge seat 58 is movably connected to the joint of the upper support rod 510 and the connecting seat 51. A tooth groove 59 is formed on one side of the outer arc surface of the hinge seat 58. The tooth groove 59 is movably clamped with the locking tooth 53. One end of the lower support rod 55 is fixedly installed with a double-rotating washing head 6.

[0037] Thus, during the process of pulling out the multi-joint telescopic rod 2, the ring sleeve 57 fixedly connected to the top end of the multi-joint telescopic rod 2 drives the lower support rod 55 to move downward in the chute 54 under tension. At this time, the movement of the lower support rod 55 causes the connected upper support rod 510 to close and contract inward. Therefore, the distance between the two double-rotating washing heads 6 approaches. A triangular structure is formed between the upper support rod 510 and the lower support rod 55 within a certain limited length of the multi-joint telescopic rod 2. Therefore, no matter how long the multi-joint telescopic rod 2 extends, it will always be supported by the upper support rod 510 and pulled by the lower support rod 55. The stretching distance of the multi-joint telescopic rod 2 can control the working range between the two double-rotating washing heads 6. It can not only protect and support the drag rod, but also increase the cleaning area of the double-rotating washing heads 6 for the photovoltaic modules, and the operation is relatively simple, enabling rapid daily cleaning and maintenance of the photovoltaic panels.

[0038] During the swinging process of the upper support rod 510, the hinge seat 58 installed at the shaft point of the connecting seat 51 will swing synchronously. Under the swing, the locking tooth 53 and the tooth groove 59 are separated, and then the lower support rod 55 is rotated. After the movement is completed, the locking tooth 53 automatically resets and engages with the tooth groove 59. Since the top ends of the tooth groove 59 and the locking tooth 53 are arc-shaped structures, they will get rid of the restriction of the locking tooth 53 during the rotation process, and the tooth groove 59 serves as a node to ensure the fixation of the upper support rod 510 after swinging and floating.
