Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic panel detection, and in particular, relates to a mobile photovoltaic panel flaw detection and maintenance robot. Background Art

[0002] As a clean, pollution-free and inexhaustible energy source, solar energy has played a very important role in the utilization of new energy in recent years, especially photovoltaic panels have been applied to many outdoor power supply facilities. Photovoltaic panels, also known as solar panels, are assemblies composed of several solar cell modules assembled on a board in a certain way. With the continuous progress of land photovoltaic panel projects in recent years, available land resources have been increasingly occupied. my country has a large available ocean area. In order to improve the utilization rate of the ocean working surface, scientific researchers have developed offshore photovoltaic panels.

[0003] However, the offshore environment is more complicated, and severe weather conditions such as thunderstorms, hail, wind and waves are often encountered. During use, the surface of the photovoltaic panel may be damaged by hail, and the damaged surface of the photovoltaic panel may have certain depressions, which may affect the normal light reception of the photovoltaic panel. At the same time, there are many fish in the ocean, and the counterweight plate placed in the sea may be hit by fish. The side wall of the counterweight plate hit by fish may be missing part of the counterweight. The missing part of the counterweight of the counterweight plate may cause the counterweight plate and the floating plate to tilt as a whole. If it is not discovered in time, it may cause the photovoltaic panel to tilt as a whole and flip in the sea. In the prior art, when performing flaw detection on photovoltaic panels, staff generally use detection instruments to perform flaw detection measurements on the surface of the photovoltaic panel. However, there are a large number of photovoltaic panels installed at sea, and the efficiency of measuring one by one may be low. When testing the counterweight plate, staff generally salvage the floating plate and use flaw detection instruments for flaw detection. Since the photovoltaic panel is heavy as a whole, the operation may be inconvenient. At the same time, the efficiency of salvaging and measuring one by one is low, and the flaw detection efficiency of the entire photovoltaic panel device needs to be further improved.

[0078] A water delivery box 11 is fixedly connected to the side wall of the second flaw detection tube 9 , a first water delivery pipe 1101 is fixedly connected to the side wall of the water delivery box 11 , a third connecting pipe 1102 is also fixedly connected to the water delivery box 11 , and a water outlet end of the third connecting pipe 1102 is connected to the second flaw detection tube 9 .

[0079] Reference Figure 6 , Figure 7 A one-way valve 3051 is provided on the first water supply pipe 1101, the third connecting pipe 1102 and the second connecting pipe 801.

[0080] A water storage box 10 is fixedly connected to the floating plate 5, a second water supply pipe 1001 is fixedly connected to the bottom side of the water storage box 10, a cover plate 501 is rotatably connected to the water storage box 10, the second water supply pipe 1001 and the cover plate 501 are fixedly connected, and the water inlet end of the first water supply pipe 1101 is placed in the water storage box 10.

[0081] Reference Figure 3 When the floating plate 5 floats on the sea surface, the counterweight plate 4 is located in the sea. When the counterweight plate 4 is located in the sea water, the sea water will be squeezed into the water storage box 10 through the second water supply pipe 1001, and the liquid level squeezed into the water storage box 10 is flush with the sea surface.

[0082] A slide groove 202 is provided in the lead screw 2, a slider 1502 is slidably connected in the slide groove 202, a pull rod 1501 is fixedly connected to the slider 1502, and the pull rod 1501 and the slide rod 15 are fixedly connected.

[0083] Reference Figure 3 , Fig.12 When the floating plate 5 floats up, the floating plate 5 will push the turntable 502 to move up, and the upward movement of the turntable 502 will push the connecting ring 12 to move up. When the connecting ring 12 moves up, the sliding rod 15 will slide on the screw rod 2, thereby ensuring that the second flaw detection head 9011 is always against the photovoltaic panel 6.

[0084] Reference Figure 1-Figure 3 , Figure 8-Figure 11 During use, the fluctuation of the waves will lift the floating plate 5, and the floating plate 5 will synchronously drive the counterweight plate 4 to move up. Since the floating plate 5, the counterweight plate 4 and the screw rod 2 are threadedly connected, the screw rod 2 will rotate at this time, and the rotation of the screw rod 2 will synchronously drive the first connecting rod 201 to rotate. When the first connecting rod 201 rotates, it will drive the first flaw detection tube 3 to rotate. The first flaw detection tube 3 will rotate around the side wall of the counterweight plate 4 for detection. When encountering a depression on the side wall of the counterweight plate 4, the first flaw detection head 3041 will extend into the depression. When the first flaw detection head 3041 extends into the depression, the first flaw detection head 3041 will instantly pull the first flaw detection rod 304 out. When the first flaw detection rod 304 is extended, it will pull the first sliding plug 302 to slide. When the sliding plug 302 slides, the first flaw detection tube 3 will extract seawater through the third water supply pipe 305, and the extracted seawater will be stored in the first flaw detection tube 3. When the first flaw detection head 3041 slides out of the recess, the first flaw detection rod 304 will slide and reset. The reset of the first flaw detection rod 304 will push the first sliding plug 302 to reset. When the first sliding plug 302 is reset, the seawater stored in the first flaw detection tube 3 will be sprayed out through the color developing tube 301, and the seawater sprayed into the color developing tube 301 will continue to increase. When the pressure reaches the threshold value set by the one-way pressure valve 3013, the seawater will flow into the upper cavity of the color developing tube 301. At this time, the color developing tube 301 will mix with the phenolphthalein reagent in the upper cavity of the color developing tube 301, and the mixed phenolphthalein reagent will turn red.

[0085] During the floating process of the floating plate 5 and the synchronous rotation of the first flaw detection tube 3, multiple groups of first flaw detection tubes 3 can detect different positions of the side wall of the counterweight plate 4. The specific number and position of the first flaw detection tubes 3 can be adjusted according to the counterweight plate 4 to ensure that the first flaw detection tubes 3 can detect the complete side wall of the counterweight plate 4 during the detection process.

[0086] Reference Figure 1-Figure 3 , Figure 5-Figure 7 , Fig.10 , Fig.12During the rotation of the screw rod 2, the screw rod 2 can synchronously drive the slide rod 15 to rotate. When the slide rod 15 rotates, it will synchronously drive the second connecting rod 1201 to rotate, and then drive the second flaw detection tube 9 to rotate. When the second flaw detection tube 9 rotates, the second flaw detection head 9011 will slide on the upper end surface of the photovoltaic panel 6. When encountering a depression on the photovoltaic panel 6, the second flaw detection head 9011 will slide into the depression. When the second flaw detection head 9011 slides into the depression, the second flaw detection head 9011 will pull the second flaw detection rod 901 down, and the second flaw detection rod 901 will pull the second slide plug 9 04 slides down, when the second sliding plug 904 slides down, the second flaw detection tube 9 will extract the seawater in the water delivery box 11 through the first water delivery pipe 1101, and the extracted seawater will be stored in the sliding cavity 903. When the second flaw detection head 9011 slides out of the depression, the second flaw detection head 9011 will push the second sliding plug 904 to slide up and reset. During the resetting process of the second sliding plug 904, the seawater in the sliding cavity 903 can be squeezed out through the second connecting pipe 801, and the squeezed seawater will flow into the color developing plate 8, and the seawater will mix with the phenolphthalein reagent in the color developing plate 8. After mixing, the phenolphthalein reagent will turn red.

[0087] By utilizing the fluctuation of the waves, the floating plate 5 is supported and floated up and down, thereby driving the screw rod 2 to rotate, and the screw rod 2 drives the first flaw detection tube 3 and the second flaw detection tube 9 to rotate, and the first flaw detection tube 3 can be used to perform depression flaw detection on the side wall of the counterweight plate 4, and the second flaw detection tube 9 can be used to perform depression flaw detection on the upper surface of the photovoltaic panel 6, by performing depression flaw detection on the counterweight plate 4, and by extracting seawater into the color developing tube 301 during flaw detection, and by mixing seawater and phenolphthalein reagent, the liquid in the color developing tube 301 appears red, so that the staff can quickly observe whether the counterweight plate 4 is damaged through the color developing tube 301 during inspection, and by performing depression flaw detection on the upper surface of the photovoltaic panel 6, and by extracting seawater into the color developing board 8 during flaw detection, and by mixing seawater and phenolphthalein reagent, the liquid in the color developing board 8 appears red, so that the staff can quickly observe whether the upper surface of the photovoltaic panel 6 is damaged through the color developing board 8 during inspection.

[0088] The photovoltaic panel 6 is inspected by the device. When the staff conducts inspection, it is no longer necessary for the staff to hold the detection instrument to inspect the surface of the photovoltaic panel 6. When the counterweight plate 4 is inspected by the device, it is no longer necessary for the staff to lift the floating plate 5 to inspect the counterweight plate 4, thereby improving the inspection efficiency of the staff.

[0095] Reference Figure 8 By setting a one-way valve 3051 on the third water supply pipe 305, the extracted seawater will not leak out through the third water supply pipe 305 when discharged.

[0096] Example 2: Reference Figure 1-Figure 3 , Figure 5 and Fig.11 A mobile photovoltaic panel flaw detection and maintenance robot is basically the same as Example 1. Furthermore, a flushing cylinder 13 is fixedly connected to the floating plate 5, and a water spray pipe 14 is fixedly connected to the side wall of the flushing cylinder 13. The water outlet of the water spray pipe 14 faces the photovoltaic panel 6. A fourth water supply pipe 1305 is fixedly connected to the bottom side of the flushing cylinder 13, and the water inlet end of the fourth water supply pipe 1305 is placed in the water storage box 10.

[0097] In order to ensure the flushing effect of the water spray pipe 14 on the photovoltaic panel 6, a filter can be set in the second water supply pipe 1001. The filter can block impurities in the seawater, so that the subsequently sprayed seawater will not carry large particles of impurities.

[0098] Both the water spray pipe 14 and the fourth water supply pipe 1305 are provided with a one-way valve 3051 .

[0099] A third sliding plug 1303 is slidably connected in the flushing cylinder 13 , and a push rod 1301 is also slidably connected to the flushing cylinder 13 . The push rod 1301 and the third sliding plug 1303 are fixedly connected.

[0100] A third connecting rod 1202 is fixedly connected to the side wall of the connecting ring 12 , and a probe 7 is fixedly connected to the third connecting rod 1202 , with the detection end of the probe 7 facing the photovoltaic panel 6 .

[0101] Probe 7 is an ultrasonic flaw detector head, model BST-900A.

[0102] The third connecting rod 1202 is also fixedly connected to a driving plate 1203 , and one end of the push rod 1301 away from the third sliding plug 1303 is fixedly connected to a driving head 1302 , so that the driving plate 1203 and the driving head 1302 abut against each other.

[0103] Reference Fig.11 A third spring 1304 is fixedly connected to the third sliding plug 1303 , and one end of the third spring 1304 away from the third sliding plug 1303 is fixedly connected to the top wall of the flushing cylinder 13 .

[0104] The third slide plug 1303 can be quickly reset by the third spring 1304 provided on the third slide plug 1303 . When the third slide plug 1303 is reset, the flushing cylinder 13 will extract seawater from the water storage box 10 through the fourth water supply pipe 1305 , and the extracted seawater will be stored in the flushing cylinder 13 .

[0105] Reference Figure 1-Figure 3 , Figure 5 and Fig.11 During the rotation of the connecting ring 12, the connecting ring 12 will also synchronously drive the third connecting rod 1202 to rotate. The rotation of the third connecting rod 1202 will synchronously drive the probe 7 fixedly connected thereto to rotate. When the probe 7 rotates, the flaw detection end of the probe 7 will scan and flaw detect the photovoltaic panel 6. By scanning and flaw detecting the photovoltaic panel 6 through the probe 7, cracks on the photovoltaic panel 6 can be scanned and flaw detected, thereby further improving the detection effect of the photovoltaic panel 6.

[0106] During the flaw detection of the photovoltaic panel 6 by the probe 7, the third connecting rod 1202 will also synchronously drive the driving plate 1203 to rotate. When the driving plate 1203 rotates and contacts the driving head 1302, the driving plate 1203 will press the driving head 1302. When the driving head 1302 is pressed, it will move downward, thereby pushing the push rod 1301 downward. The push rod 1301 will synchronously push the third sliding plug 1303 downward. During the sliding movement of the third sliding plug 1303, the seawater stored in the flushing cylinder 13 will be sprayed out through the water spray pipe 14, and the sprayed water will impact the photovoltaic panel 6. The photovoltaic panel 6 will be flushed by the impacting seawater. On the one hand, it can wash away the dust and impurities on the surface of the photovoltaic panel 6, and on the other hand, it can flush out the impurities in the cracks. By flushing out the impurities in the cracks, the detection accuracy of the probe 7 for the cracks can be improved.
