[0002] Water quality monitoring involves monitoring and measuring the types, concentrations, and trends of pollutants in water. Buoy-type water quality monitoring stations are a common monitoring device used extensively in various water bodies. These buoy-type water quality monitoring stations are typically solar-powered and equipped with photovoltaic panels. To ensure stable operation, these panels must be cleaned regularly to maintain their efficiency.

[0003] Buoy water quality monitoring stations that have been in the wild for a long time cannot carry clean water for a long time. Taking water on site requires separating floating objects in the water body. Especially in some waters that are seriously polluted and contain a large amount of particulate matter, in order to separate and obtain cleaner water, it is necessary to install water purification equipment, which leads to higher cleaning costs for solar photovoltaic panels.

[0034] See also Figures 1 to 6 This embodiment provides a water quality monitoring device, including a float 1, a mounting seat 2, a solar photovoltaic panel 3, a cleaning member 4 and a driving device 5, wherein the cleaning member 4 includes a cleaning portion 41 and a water absorbing portion 42.

[0035] The float 1 floats on the surface of the monitored water area, the mounting seat 2 is set on the float 1, the solar photovoltaic panel 3 is set on the mounting seat 2, and the cleaning member 4 has a cleaning part 41 and a water absorbing part 42 connected to each other. The water absorbing part 42 can contact the water surface, and the cleaning part 41 can move back and forth on the solar photovoltaic panel 3 to clean the solar photovoltaic panel 3. After the water absorbing part 42 contacts the water, the water moves to the cleaning part 41 through the capillary effect. Specifically, the water absorbing part 42 can always be in the water, or it can only maintain short-term contact with the water and then separate from the water surface ( Figure 1 In this case, the cleaning unit 41 can move back and forth on the surface of the solar photovoltaic panel 3 or can be out of contact with it. The driving device 5 is used to drive the cleaning unit 41 to move. The driving device 5 can directly drive the cleaning unit 41 to move, or it can achieve the purpose of driving the cleaning unit 41 to move by driving the entire cleaning member 4 to move.

[0036] In this embodiment, the water absorbing portion 42 contacts the water surface, and water moves toward the cleaning portion 41 through a capillary effect, thereby keeping the cleaning portion 41 moist. During this process, the water is filtered, and the water delivered to the cleaning portion 41 is relatively clean and can be used to clean the solar photovoltaic panel 3, thereby reducing the cost of obtaining clean water for the solar photovoltaic panel 3. Driven by the driving device 5, the cleaning portion 41 cleans the solar photovoltaic panel 3.

[0037] The water quality monitoring device also includes components not shown, such as a control box and a fixed anchor.

[0038] In one embodiment, the cleaning member 4 is preferably cotton cloth, which has a strong capillary effect and low cost.

[0039] In one embodiment, two guide rails 21 are further included, and the driving device 5 includes a first support shaft 51 , a motor 53 and two belt transmission mechanisms 52 .

[0040] Two guide rails 21 are mounted on the mounting base 2 and are arranged parallel to each other on either side of the solar photovoltaic panel 3. The ends of a first support shaft 51 slideably engage the two guide rails 21. The first support shaft 51 is connected to the cleaning portion 41. Preferably, the cleaning portion 41 is wound and secured to the first support shaft 51, allowing the cleaning portion 41 to store more water and improve cleaning effectiveness. Two belt drive mechanisms 52 are located inside the two guide rails 21. A motor 53 drives the belt drive mechanisms 52, which in turn slide the first support shaft 51.

[0041] In this embodiment, the motor 53 drives the transmission belt 521 and the transmission mechanism 52 to move, thereby directly or indirectly driving the first support shaft 51 to slide on the guide rail 21. The cleaning part 41 and the water absorption part 42 move with the first support shaft 51, and the cleaning part 41 cleans the solar photovoltaic panel 3 during movement.

[0042] In one embodiment, a second supporting shaft 61 and a shielding member 62 are further included.

[0043] The two ends of the second support shaft 61 are slidably engaged with the guide rails 21 on both sides. One end of the shielding member 62 ( Figure 1 The left end of the shielding member 62 is connected to the second support shaft 61, and the other end of the shielding member 62 ( Figure 1 The right end in FIG) is connected to the first support shaft 51. When the water absorption part 42 moves above the solar photovoltaic panel 3, the shielding member 62 is located between the water absorption part 42 and the solar photovoltaic panel 3.

[0044] In this embodiment, Figure 3 As shown, the cleaning member 4 is not long, that is, the distance between the water absorbing portion 42 and the cleaning portion 41 is not far, which helps to reduce the distance that water moves, prevents water from evaporating during movement, and allows more water to move to the cleaning portion 41. In addition, the water absorbing portion 42 is preferably wider than the solar photovoltaic panel 3, so that the contact area with the water absorbing portion 42 when absorbing water is large, thereby allowing more water to move to the cleaning portion 41 through the capillary effect. In order to ensure the capillary effect of the cleaning member 4, the water absorbing portion 42 is preferably a whole piece of cloth, rather than several strips of cloth connected to the cleaning portion 41, in order to increase the contact area with water. The water absorbing portion 42 is in water for a long time, and a large amount of water impurities and floating objects on the water surface are attached to its surface. When the cleaning portion 41 moves to the upper surface of the solar photovoltaic panel 3 to clean it, the water absorbing portion 42 separates from the water and gradually moves above the solar photovoltaic panel 3. The contact between the water absorbing portion 42 and the solar photovoltaic panel 3 will contaminate the solar photovoltaic panel 3.

[0045] Therefore, the shielding member 62 can effectively separate the water absorbing portion 42 from the solar photovoltaic panel 3 to avoid contamination of the solar photovoltaic panel 3 .

[0046] In one embodiment, the driving device 5 further includes two transmission columns 54 slidably arranged on the guide rails 21 on both sides. The transmission columns 54 are located between the first support shaft 51 and the second support shaft 61. The transmission columns 54 can push the first support shaft 51 or the second support shaft 61 to move.

[0047] In this embodiment, the motor 53 drives the belt 521 to move the transmission mechanism 52, thereby causing the transmission column 54 to slide. Figure 1 The transmission column 54 slides to the right, pushing the first support shaft 51 to slide to the right, driving the cleaning part 41 to clean the solar photovoltaic panel 3. The transmission column 54 slides to the left, driving the second support shaft 61 to slide to the left, and then driving the first support shaft 51 to slide to the left, and the water absorption part 42 re-enters the water.

[0048] In one embodiment, the guide rail 21 includes a horizontal section 211, an arc section 212 and a vertical section 213. The horizontal section 211 is arranged horizontally. The two ends of the arc section 212 are connected to the horizontal section 211 and the vertical section 213 respectively. Specifically, the upper end of the arc section 212 is connected to the horizontal section 211. The upper end of the vertical section 213 is connected to the arc section, and the vertical section 213 is connected to the mounting base 2. Specifically, the vertical section 213 can be vertically downward or inclined. The above-mentioned horizontal section 211, arc section 212 and vertical section 213 all refer to Figure 4 The middle and left parts of the guide rail 21. The right part of the guide rail 21 in the figure can be arranged according to the shape of its left part as shown in the figure, and the arc section and the vertical section 213 can be no longer arranged, and it can be directly connected to the mounting base 2.

[0049] The shielding member 62 includes a first shielding plate 621 and a second shielding plate 622 .

[0050] The first shielding plate 621 is hinged to the second support shaft 61. One end of the second shielding plate 622 ( Figure 1 and Figure 2 The left end of the second baffle is hinged to the first baffle 621, and the other end of the second baffle ( Figure 1 and Figure 2 The right end in FIG) is hinged to the first support shaft 51.

[0051] In this embodiment, Figure 1 At this point, both the second support shaft 61 and the first support shaft 51 are located in the horizontal section 211 of the guide rail 21. Driven by the belt drive mechanism 52, the drive column 54 drives the first support shaft 51 to move rightward. The cleaning portion 41 wipes and cleans the solar photovoltaic panel 3. The first and second shielding plates 621 and 622 support and shield the water absorption portion 42 above, preventing the water absorption portion 42 from contaminating the solar photovoltaic panel 3. After cleaning is complete, the drive column 54 drives the second support shaft 61 to move leftward. The second support shaft 61, through the first and second shielding plates 621 and 622, drives the first support shaft 51 to move leftward. The second support shaft 61 slides from the horizontal section 211 and the arc section 212 to the bottom of the vertical section 213. At this time, the first support shaft 51 also begins to repeat the route of the second support shaft 61. In particular, after the first support shaft 51 enters the vertical section 213, the first support shaft 51 and the second support shaft 61 approach each other. Since the first shielding plate 621 and the second shielding plate 622 are connected by hinges, the first shielding plate 621 and the second shielding plate 622 begin to fold. When the first support shaft 51 falls above the second support shaft 61, the first shielding plate 621 and the second shielding plate 622 are stacked together and horizontally to the left, and the water absorption portion 42 thereon is supported, which has the following two effects:

[0052] First, the first baffle plate 621 and the second baffle plate 622 support the water absorption part 42, so that the water absorption part 42 can extend outward, that is, the guide rail 21 of the present device can be only arranged above the mounting seat 2, and the water absorption part 42 can also be supported to the left and located above the water body, and then enter the water, which makes the guide rail 21 smaller in size, reduces the risk of rollover of the entire device, reduces manufacturing costs, and makes the device more compact.

[0053] Secondly, in addition to the above-mentioned effects of shielding the water absorption part 42 and supporting the water absorption part 42 to the left to reduce the structural size of the device, the first baffle plate 621 and the second baffle plate 622, during the folding process, the water absorption part 42 is always supported by the baffle plates, and at this time, the left side of the two baffle plates (i.e., the hinge connection) has a downward scraping effect on the water absorption part 42, scraping off the moss, water pollution particles or floating objects adhered to the water absorption part 42 that has been in the water for a long time, thereby forming a certain degree of cleaning for the water absorption part 42, so that water can enter the water absorption part 42 more smoothly, thereby improving the effect of the subsequent capillary effect.

[0054] In addition, the structure of the guide rail 21 is described in detail: the horizontal section 211, the arc section 212 and the vertical section 213 of the guide rail 21, each section includes two parallel tracks, and the parallel tracks constitute the inner rail 214 and the outer rail 215. A guide bar 216 is provided along the length direction on the opposite side of the inner rail 214 and the outer rail 215, and a guide groove 511 is provided along the circumferential direction on both ends of the first support shaft 51 and the second support shaft 61 and the transmission column 54. The guide bar 216 and the guide groove 511 are slidably matched. The ends of the inner rail 214 and the outer rail 215 are connected to each other to form a closed loop to prevent the first support shaft 51 from slipping. The inner rail 214 is connected to the mounting base 2.

[0055] In one embodiment, the belt drive mechanism 52 includes a transmission belt 521, a guide wheel 522, a take-up wheel 523, and a connecting shaft 524. Two transmission belts 521 are provided, arranged along the inner rail 214 on the same side and connected to the transmission column 54. One guide wheel 522 is provided at the arcuate section 212 of each inner rail 214, rotatably mounted on the inner side of the inner rail 214, and in contact with the transmission belt 521. One take-up wheel 523 is rotatably provided at the vertical section 213 of each inner rail 214 and connected to the end of the transmission belt 521. Two connecting shafts 524 are provided, and the ends of the connecting shafts 524 are coaxially connected to the corresponding take-up wheels 523. A transmission gear is sleeved on the connecting shaft 524, and a drive gear is sleeved on the rotating shaft of the motor 53, and the drive gear and the transmission gear are meshed.

[0056] In this embodiment, the motor 53 drives the connecting shaft 524 to rotate, thereby driving the winding wheel 523 to reel. Figure 1In the figure, the left motor 53 rotates to drive the two left winding wheels 523 to rewind (the left front winding wheel 523 rotates counterclockwise), which in turn drives the transmission column 54 to abut against the two ends of the second support shaft 61 through the transmission belt 521, causing the second support shaft 61 to move leftward. Similarly, the rotation of the right motor 53 drives the first support shaft 51 to move rightward.

[0057] In the description of the present invention, a large number of specific details are described. However, it is understood that embodiments of the present invention can be practiced without these specific details. In some instances, well-known methods, structures, and techniques are not shown in detail so as not to obscure the understanding of this description.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
