Description

  The present invention relates to an apparatus for cleaning a solar cell panel installed on a flat ground or a roof of a house.

  In recent years, with the growing awareness of the environment, power generation methods using renewable energy that does not emit carbon dioxide have attracted attention. Among them, power generation systems that use solar panel panels that are relatively easy to construct are rapidly spreading. Have been doing. However, since the solar cell panel is always installed outdoors, it has the following problems. That is, dirt such as dust and yellow sand gradually adheres to the surface of the solar panel over time. If this dirt is left unattended, the transmittance of sunlight in the solar panel decreases. As a result, the amount of power generation is reduced. In addition, if foreign matter such as bird droppings or fallen leaves adheres to a part of the surface of the solar cell panel and shields it from light, a so-called hot spot phenomenon occurs in which the part generates heat, which may damage the solar cell panel. Sometimes. Therefore, as an apparatus for solving such a problem, an apparatus for cleaning dirt adhering to the surface of a solar cell panel while rotating a brush has been proposed (Patent Documents 1 and 2).

JP 2004-186632 A JP 2011-36833 A

  However, as in the inventions described in Patent Documents 1 and 2, if the main body for removing dirt is a brush, if the brush material is hard, the surface of the solar cell panel is damaged. There is a risk of reducing the transmittance of sunlight in the solar cell panel. Conversely, if the material of the brush is made soft, it will inevitably be worn, and the brush will need to be replaced frequently. In addition, it can be said that it is difficult to completely remove dirt firmly attached to the panel such as bird droppings with a soft brush.

  The present invention has been made to solve the above-mentioned problems, and it is necessary to completely remove the adhered dirt without damaging the surface of the solar cell panel and to frequently replace the main body for removing the dirt. It aims to provide a solar panel cleaning device that does not.

  To achieve this object, a solar cell panel cleaning apparatus according to the present invention includes a pair of guide rails provided along a longitudinal direction of a plurality of solar cell panels arranged on a gantry, and the pair of guide rails. A cleaning device for a solar cell panel comprising a cleaning body guided and moved on the solar cell panel, wherein the cleaning body is a frame body and a predetermined position with respect to the traveling direction of the frame body inside the frame body. It is characterized by comprising a plurality of wiper members arranged so as to be arranged at intervals, and moving means arranged on both sides of the frame body and traveling on the guide rail.

  Moreover, it is preferable that a plurality of the wiper members are also arranged in a direction orthogonal to the traveling direction.

  Further, it is preferable that the wiper members are alternately arranged so as to be alternately arranged in the traveling direction.

  Moreover, it is preferable that the said wiper member is arrange | positioned so that the inner edge part may mutually overlap when seeing from a running direction.

  According to the present invention, attached dirt can be removed without scratching the surface of the solar cell panel. In particular, since the dirt adhered to the surface of the solar cell panel is removed by the plurality of wiper members, the dirt can be completely removed.

  Furthermore, since the present invention employs the wiper member as a main body for removing dirt on the solar cell panel, the replacement frequency can be remarkably reduced as compared with the case where the main body is a rotating brush or the like. In other words, the wiper rubber used for the wiper member can be used without being damaged so much even if it is used for a long time in a situation where it is exposed to the sun, as you can imagine from what is used in automobiles. You can continue. Similarly, even if the wiper member employed in the present invention is used for a long period of time, it is less damaged and the replacement frequency thereof is reduced, so that the cost due to aging can be reduced.

Are mounted on the holding frame 3e of the gantry 3 to constitute a solar cell array A.

  The cleaning device 1 according to the present invention is applied to the above-described photovoltaic power generation system, and is guided by the pair of guide rails 5 and 5 and the guide rails 5 and 5 and on the solar cell panels 2, 2. It is comprised by the cleaning body 6 which moves.

  The pair of guide rails 5, 5 is a solar cell array A configured by arranging a plurality of solar cell panels 2, 2... In the longitudinal direction of the solar cell panels 2, 2. Are provided in the vicinity of the front and rear end portions so as to be parallel to the front and rear end portions. In addition, the guide rails 5 and 5 are provided so that both ends thereof protrude from the corners of the solar cell array A. The guide rail 5 is for driving a wheel 7 as a moving means of the cleaning body 6 to be described later, and is formed in a rectangular tube shape by bending a long metal plate. Specifically, as shown in FIG. 3, the guide rail 5 includes a bottom plate portion 5 a on which the wheel 7 is placed, an outer plate portion 5 b that is bent upward at an end portion of the bottom plate portion 5 a, and a lower piece. Part 5c, a top plate part 5d bent one end of the outer plate part 5b forward, and an upper piece part 5e bent one end part of the top plate part 5d downward. A slit-like gap S is formed between the pieces 5e. And the guide rail 5 is being fixed to the support | pillar 3c of the mount frame 3 through the reinforcing bar I mentioned above. That is, one end of a plurality of rebars I cut to a predetermined length is welded to a plurality of columns 3c, 3c... Of the gantry 3, and the other end of the rebar I is a lower piece of the guide rail 5. It is welded to several places of the part 5d. Further, as shown in FIGS. 1 and 2, a cleaning body standby portion 8 is formed at the left end portion of the guide rails 5 and 5 and the cleaning body 6 is on standby when the cleaning body 6 is not in operation. Although not shown, the body standby unit 8 is provided with a power source for supplying power to the battery of the cleaning body 6. On the other hand, a cleaning body folding part 9 is formed at the right end of the guide rails 5 and 5 to be folded when the cleaning body 6 has completely moved from the left to the right on the solar cell array A. In this embodiment, an example in which the guide rail 5 is mounted on the column 3c of the gantry 3 via a reinforcing bar has been described. However, the guide rail 5 may be mounted on another part of the gantry 3. Further, for example, a guide rail may be installed by providing a support on the bottom surface of the bottom plate portion 5a of the guide rail 5 and embedding the support in the ground. That is, as long as the guide rails 5 and 5 are provided in the vicinity of the front and rear end portions of the solar cell array A, any method may be employed for the installation.

  The cleaning body 6 includes a frame body 10, a plurality of wiper members 11 provided inside the frame body 10, wheels 7 and 7 as moving means provided on both sides of the frame body 10, and an upper side of the frame body 10. The cover member 13 is mounted so as to cover it.

  As shown in FIG. 4, the frame body 10 in this embodiment is provided with two metal-made fixing plates (fixing members) 14 and 14 having a trapezoidal shape, separated by a predetermined distance, .. Are formed by horizontally laying six connecting rods 15, 15... As support members between the fixed plates 14, 14, that is, inside the two fixed plates 14, 14. Specifically, six through holes are formed in each of the fixing plates 14 and 14 at predetermined intervals, and the ends of the connecting rods 15, 15... Are inserted into the through holes and fixed. It is fastened and fixed with a nut from the outside of the plate 14. In addition, these six connecting rods 15, 15... Are arranged adjacent to each other relatively close to each other, and the interval between each of the two connecting rods and the other two connecting rods is two adjacent ones. It is arranged slightly apart from the connecting rod. These connecting rods 15, 15... Are not shown, but can be divided into two. Of the two divided rods, the female screw portion formed on one end of one of the rods is connected to the other. A single connecting rod 15 is formed by screwing a male screw portion formed at one end of the rod.

  A plurality of frames 10 are arranged inside the frame body 10 with respect to the traveling direction and with respect to the direction orthogonal to the traveling direction. Specifically, six wiper members 11, 11... Are alternately mounted inside the frame body 10 so as to be alternately arranged in the traveling direction at a predetermined interval. Specifically, as shown in FIGS. 4 and 5, the wiper members 11 are suspended from the connecting rods 15, 15. That is, the wiper member 11 is mounted on the front side (lower side in FIG. 5) of the wiper member 11 at the right side, and the wiper member 11 is placed on the far side of the connecting bar 15 from the left side. And the wiper members 15 are mounted on the connecting rod 15 on the back side so that the wiper members 11 are alternately positioned so that the wiper member 11 is mounted on the right side. Further, the plurality of wiper members 11, 11... Are arranged so that the inner end portions of the adjacent wiper members 11, 11 are superposed on each other when viewed from the traveling direction, thereby forming a polymerization site K. Further, since the connecting rods 15, 15 for suspending the wiper members 11, 11 are close to each other as described above, the two wiper members 11 are also close to each other. The wiper member 15 is a well-known member that is generally used, and includes a wiper lever 16, a wiper blade 17, and a wiper rubber 18, as shown in FIGS. The wiper rubber 18 is applied with an appropriate pressing force to the solar cell panel 2 by the wiper lever (elastic member) 16 when the cleaning body 6 is operated. The wiper member 15 is rotatably attached to the connecting rod 15 via a rubber attachment band 19. The wiper rubbers 18, 18... Of the wiper members 11, 11... Are of three types of hardness, and the hardness of the rubber decreases from the near side to the back. . Specifically, the left and right wiper rubbers 18 and 18 positioned on the front side (lower side in FIG. 5) are relatively hard, and the left and right wiper rubbers 18 and 18 positioned in the middle are used. Is a softer one that is lower in hardness and slightly softer than that described above, and the left and right wiper rubbers 18 and 18 located on the back side (upper side in FIG. 5) are softer in hardness. ing. In addition, a plurality of cuts are provided at an appropriate pitch at the lower end of the wiper rubber 18.

  Drive motors 21 and 21 and batteries 22 and 22 are mounted side by side on the outer surfaces of the fixing plates 14 and 14 of the frame body 10 via mounting brackets 20 respectively. In addition, wheels 7 and 7 serving as moving means for running the guide rail 5 are attached to the tip portions of the rotary shafts 23 and 23 that protrude outward from the drive motors 21 and 21. Further, ball receiving members 24 in which balls 24 are housed are attached to the most distal portions of the rotary shafts 23 and 23, respectively, as shown in FIG. Although not shown, a control board for controlling the operation of the cleaning body 6 is disposed below the drive motor 21 and the battery 22. Incidentally, the length from the tip of one rotating shaft 22 to the tip of the other rotating shaft 22, in other words, the total length of the cleaning body 6 is set to 340 cm.

  The cover member 13 is formed of FRP (fiber reinforced plastic) and is detachably mounted on the fixing plates 14 and 14 of the frame body 10 so as to cover the upper part of the frame body 10. The cover member 13 is formed in a box body having an open lower side with a substantially trapezoidal cross section, and can be divided into two. That is, as shown in FIG. 4, a superposed portion 31 is provided at a substantially central portion of one cover member 30 a that is lowered stepwise to approximately the same thickness as the thickness of the cover. The two members are combined by sliding and sliding, and further engaging a hook (not shown) provided on the back side of the other cover member 30b with a protrusion (not shown) provided on the back side of the one cover member 30a. Be able to. Further, although not shown, a raindrop detection sensor that detects rainy weather is attached to the upper portion of the cover member 13.

  As shown in FIGS. 1 and 2, the frame body 10 of the cleaning body 6 is not dimensioned to cover the entire short side of the array A, but this is located at the top of the array A. The solar cell panel to be used is based on the reason that it is relatively easy to remove dirt due to rain or the like, and does not need to be cleaned as much. However, as a matter of course, the frame body may be formed so as to cover the entire short direction of the array.

  Here, the assembly method in the field of the cleaning body 6 of the washing | cleaning apparatus 1 comprised as mentioned above is demonstrated. Since the cleaning body 6 has a long total length of 340 cm, it is difficult to store the cleaning body 6 in an automobile or the like as it is when transported to the site by an automobile or the like. Therefore, the cleaning body 6 is configured to be divided so that it can be easily assembled on site. That is, when the cleaning body 6 is transported by an automobile, a connecting plate in which a driving motor 21, a battery 22, and a fixed plate 14 on which wheels 7 are mounted in advance is set on one side and a wiper member 11 is mounted in advance and divided in two. 15 is brought into the field in the state of 12 and the cover members 30a and 30b divided into two. In the field, first, one end of the connecting rod 15 is inserted into the through hole of one fixing plate 14 from the inside, and a nut is fastened to one end of the connecting rod 15 protruding outward to fix the connecting rod 15 to the fixing plate 14. To do. When the six connecting rods 15 are fixed to the fixing plate 14 in this way, the six connecting rods 15 remaining at the end of the connecting rod 15 opposite to the fixing plate 14 are screwed. That is, the connecting rod 15 that has been divided by screwing the male screw portion of the other connecting rod into the female screw portion of one connecting rod 15 is combined. Next, one end of the connecting rod 15 on which the fixing plate 14 is not mounted is inserted into the through hole of the other fixing plate 14 from the inside, and a nut is tightened to one end of the connecting rod 15 protruding outward to fix the fixing plate 14. It sticks to. This operation is performed for all the connecting rods 15, 15... To complete the frame body 10. Further, after the other cover member 30b is slid to the overlapping portion 31 of the one cover member 30a that is divided into two, the protrusion provided on the back side of the one cover member 30a is provided on the back side of the other cover member 30b. The cover member 13 is integrated by locking the hooks. Finally, the cover member 13 is attached to the upper part of the frame body 10 and various wirings are connected to complete the assembly of the cleaning body 6. As described above, the cleaning body 6 can be divided so as to be easily assembled on site. For example, in the case of a large-scale solar power generation system called a mega solar, the solar cell array A is divided into a plurality of sections. If an attempt is made to install the cleaning device 1 for each of such a plurality of sections, the cost increases significantly. On the other hand, when looking at the operation status of large-scale mega solar systems, the part where the dirt on the solar cell panel is particularly severe does not extend to the entire part, but is often only a part of the part adjacent to the forest. Of course, other parts will gradually become dirty over time, so it is not necessary to clean them at all. Therefore, a cleaning device is permanently installed in a particularly dirty area, and only the guide rails 5 and 5 are installed in other areas, and the cleaning body 6 is transported as necessary, and the cleaning of the area is completed. It is preferable to take it home again. In such a case, if the cleaning body 6 can be divided to such an extent that it can be easily assembled on site, the cleaning body 6 can be easily transported by an automobile or the like, so that the usability is remarkably improved.

  Next, the cleaning operation by the cleaning apparatus 1 will be described. The cleaning body 6 basically does not operate as long as it is sunny, and is located in the cleaning body standby part 8 at the left end of the guide rails 5 and 5. On the other hand, when it rains, water droplets are detected by the raindrop detection sensor provided on the upper part of the cleaning body 6, and the detection information is transmitted to the control board provided on the frame body 10 of the cleaning body 6. As a result, the drive motors 21 and 21 are operated, and the wheels 7 and 7 move rightward on the guide rails 5 and 5. At this time, the wiper members 11, 11... Of the cleaning body 6 also move to the right while contacting the solar cell panel 2. In addition, since the wiper rubber 18 of the wiper member 11 applies a pressing force to the solar cell panel 2 side by the wiper lever 16, when the cleaning body 6 moves, the dirt attached to the solar cell panel 2 in the solar cell array A Is wiped off by the wiper rubber 18 together with rain water. In particular, since the hardness of the wiper rubber 18 gradually becomes softer from the front side to the back side, first, the dirt on the solar cell panel 2 is caused by the soft wiper rubbers 18 and 18 on the back side that first contact the solar cell panel 2. Is removed lightly, and then the dirt of the solar panel 2 is further removed by the slightly hard wiper rubbers 18 and 18 located in the middle. Next, the hard wiper rubbers 18 and 18 located on the front side of the solar panel 2 are removed. Dirt can be completely removed. Incidentally, since the holding frame 3e is mounted around the solar cell panel 2, the portion of the holding frame 3e is slightly higher than the surface of the solar cell panel 2. That is, a slight level difference occurs between the surface of the solar cell panel 2 and the holding frame 3e. However, since the wiper rubber 18 has a plurality of cuts at a predetermined pitch, the wiper is also near the level difference. Generation | occurrence | production of the non-contact part of the rubber | gum 18 can be prevented, and dirt can be removed reliably. When the cleaning body 6 moves on the solar cell array A and reaches the right end in this way, the cleaning body 6 goes over the end to the cleaning body folding portion 9 and is detected by the sensor at the cleaning body folding portion 9. Change the direction of travel and return to the left. And when the cleaning body 6 comes to the cleaning body standby part 8 again, it will be detected by the sensor, will change the advancing direction, and will move to the right side again. The cleaning body 6 repeats such a reciprocating motion an arbitrary number of times, and finally stops at the cleaning body standby unit 8.

  Incidentally, as described above, the cleaning body 6 in the present embodiment is automatically operated in the rain by the raindrop sensor, so that the solar cell panel is not necessarily provided near the cleaning device 1 even if there is no water supply facility. Two cleanings can be performed. In addition, since the solar cell panel is washed only in rainy weather when the power generation efficiency is poor, there is also an advantage that it does not interfere with the power generation in the fine weather when the power generation efficiency is good.

  Moreover, the cleaning body 6 in this Embodiment is charged while it is located in the cleaning body standby part 8. FIG. That is, the cleaning body standby unit 8 is provided with a charging device so that the batteries 22 and 22 of the cleaning body 6 can be charged with electric power while the cleaning body 6 is positioned in the cleaning body standby unit 8. It has become. In charging the cleaning body 6, a non-contact charging device can also be employed.

  Incidentally, in the said embodiment, although the example which the cleaning body 6 of the washing | cleaning apparatus 1 operate | moves only on rainy weather was shown, it is not restricted to this, For example, the timer set to the cleaning body 6 and the time set to the said timer It is also possible for the operator to bring the cleaning device 1 to the site and manually operate the cleaning body 6.

  Furthermore, in the said embodiment, although the example which applied the washing | cleaning apparatus of the solar cell panel which concerns on this invention to the ground installation type solar power generation device called what is called standing was shown, the sunlight installed in the roof etc. of a house Of course, it can be used for a power generator.

  FIG. 8 shows a second embodiment in which the frame body 10 of the cleaning body 6 is modified. In addition, the same code | symbol is attached | subjected and demonstrated to the same component as above-described 1st Embodiment. The frame body 10 of the second embodiment is configured by providing another fixing plate 14 ′ between the fixing plates 14 and 14 on both sides. And six connecting rods 15 ', 15' ... are horizontally mounted between the fixing plates 14, 14 on both sides and the intermediate fixing plate 14 'so as to be staggered on the left and right. And the wiper members 11, 11 ... are suspended from these six connecting rods 15 ', 15' ..., respectively. In addition, these wiper members 11, 11... Are arranged in close proximity to each other, and the distance between the two wiper members and the other two wiper members is slightly separated from the two adjacent wiper members. Has been. Further, these wiper members 11, 11... Are arranged such that the ends of the adjacent wiper members 11, 11. The intermediate fixing plate 14 ′ has a lower length in the height direction than the fixing plates 14, 14 on both sides because the wiper members 11, 11. And in assembling the frame body 10 of the cleaning body 6 in this embodiment, the fixing plate 14 to which the drive motor 21, the battery 22 and the wheel 7 are mounted in advance is a left and right set, an intermediate fixing plate 14 ′, Six connecting rods 15 'to which the wiper member 11 is mounted in advance are prepared. Then, one end of the connecting rod 15 'is inserted into each through hole of one fixing plate 14 from the inside, and a nut is tightened to one end of the connecting rod 15' protruding outward to fix the three connecting rods 15 'to the fixing plate. 14 is fixed. Next, three connecting rods 15 ′ are fixed to the other fixing plate 14 in the same procedure. When three connecting rods 15 are fixed to the respective fixing plates 14 in this way, the fixing plate 14 ′ is disposed between the two fixing plates 14 and 14. Then, the connecting rods 15 'are inserted into through holes of the fixing plate 14' located at the end opposite to both the fixing plates 14 and 14, and the connecting rod 15 'protruding from the fixing plate 14' is inserted into the through hole. Tighten the nut to one end and fix it. This completes the assembly of the frame body 10.

  FIG. 9 shows a third embodiment in which the frame body 10 of the cleaning body 6 is modified. In addition, the same code | symbol is attached | subjected and demonstrated to the same component as above-described 1st Embodiment. In the frame body 10 of the third embodiment, the wiper members 11, 11,... Are further subdivided in the frame body 10 of the first embodiment. In other words, the configuration is the same as that of the first embodiment except that the wiper members 11, 11. Specifically, six connecting rods 15, 15 are horizontally placed between fixed plates 14, 14 arranged at a predetermined interval, and these six connecting rods 15, 15,. Of these, two adjacent ones are arranged relatively close to each other, and the interval between the two connecting rods and the other two connecting rods is arranged slightly apart from the two adjacent connecting rods. Of these connecting rods, two wiper members 11 are suspended from one connecting rod 15. Furthermore, these wiper members 11 are suspended in the connecting rods 15 and 15 adjacent to each other so as to be alternately left and right. That is, the wiper members 11 and 11 are attached to the connecting rod 15 on the near side (lower side in FIG. 9) at the right end position and the center from the left, and the connecting rod 15 on the far side is connected to the left end. The wiper members 15 are mounted so that the left and right wiper members 11 and 11 are alternately positioned so that the wiper members 11 and 11 are mounted in the center from the position and the right. Further, the plurality of wiper members 11, 11,... Are arranged such that the inner end portions of the adjacent wiper members 11, 11 overlap each other when viewed from the running direction, and a polymerization site K is formed. Further, since the two connecting rods 15, 15 for suspending the wiper members 11, 11 are close to each other, the wiper member 11 also has two wiper members 11, 11 on the near side and more than that. The wiper members 11 and 11 on the back side are close to each other, and the wiper members 11 and 11 located on the back side are spaced apart. The connecting rods 15 and 15 as support members in the third embodiment can also be divided into two, although not shown. Incidentally, in the frame body 10 described in the third embodiment, one or two fixing plates can be arranged between the fixing plates 14 and 14.

  In addition, in the said 1st thru | or 3rd Embodiment, although it demonstrated as the fixing plates 14 and 14, ie, a plate-shaped member, as a fixing member arrange | positioned at predetermined intervals, it does not necessarily need to be plate-shaped. . In the first to third embodiments, the connecting rods 15, 15..., I.e., rod-shaped members have been described as examples of the supporting members. However, the supporting members are not necessarily rod-shaped. For example, a plate-like member as a support member may be horizontally placed between two fixed plates as fixed members arranged at a predetermined interval, and the wiper member may be suspended from the plate-like member. . In the above-described embodiment, the example has been described in which the hardness of the wiper rubber 18 of the wiper members 11, 11... Is softened from the near side to the far side, but this is also arbitrary. That is, the arrangement of hardness as described above is most preferable, but for example, the order of hardness can be reversed, and the hardness of a plurality of wiper members can be all the same. Furthermore, it is possible to arbitrarily select such as changing the hardness of only the wiper rubber located in the middle.

  Moreover, in the said 1st thru | or 3rd Embodiment, although the frame body 10 showed the example comprised by the fixing plates 14 and 14 and the connection rods 15, 15, ..., it does not necessarily have such a structure. Not limited. Specifically, the cover member of the embodiment can be a frame body. That is, a box body having a lower opening may be used as a frame body, and the wiper member may be suspended from the ceiling portion.
