Wheels are provided at the bottom of the goods vehicle, and a cargo box is fixedly connected to the outer wall of the goods vehicle. A photovoltaic panel is fixedly connected to the top of the cargo box, and a dust-proof mechanism is arranged on the top of the cargo box.

[0013] Preferably, a telescopic sleeve is slidably connected to the outer wall of the scraper block, and the outer wall of the telescopic sleeve is slidably connected to the outer wall of the sliding plate.

[0014] Preferably, the top of the sliding plate is rotatably connected to a rotating shaft, the outer wall of the rotating shaft is fixedly connected to an opening and closing plate, the outer wall of the opening and closing plate is fixedly connected to a magnetic block B, the outer wall of the magnetic block B contacts a magnetic block A, and the outer wall of the magnetic block A is fixedly connected to the outer wall of the rotating shaft.

[0015] Preferably, the opening and closing plate and the magnetic block A are magnetic, and the magnetism of the opening and closing plate and the magnetic block A on the opposite side is that opposite poles attract each other.

[0016] Preferably, the outer wall of the opening and closing plate is fixedly connected with a square plate, the outer wall of the square plate is fixedly connected with a spring, and one end of the spring is fixedly connected with the outer wall of the scraper.

[0017] The present invention provides a photovoltaic module on the roof of a commercial cargo vehicle, which has the following beneficial effects:

[0018] 1. The present invention sets a dustproof mechanism, so that the sliding plate outside the photovoltaic panel will be blown by the wind, and because the surface of the sliding plate facing the front of the cargo box is an arc-shaped surface, the air will quickly push the sliding plate to slide on the outer wall of the limit rod, thereby driving the scraper below to move synchronously, so that when driving, the outer wall of the surface of the photovoltaic panel is automatically scraped by the scraper, and the dust particles that have been left on the surface of the photovoltaic panel for a night or a few days are scraped off, thereby ensuring the cleanliness of the surface of the photovoltaic panel during driving and avoiding the problem that the photovoltaic panel is blocked and affects the effect of solar power generation.

[0019] 2. The present invention provides a dust-proof mechanism. When the truck is traveling for a long time, the scraper and the sliding plate will be blown by the wind to slide to the fixed block B, and the wind will keep pushing the sliding plate and be discharged through the through grooves opened on the inner wall of the sliding plate. The opening direction of the through grooves on the inner wall of the sliding plate is inclined downward, so the residue entering the through grooves from the front will be discharged from the back of the sliding plate, and along with the inclined downward direction of the through grooves, the residue will be blown to the lower back of the sliding plate. The blown air will blow to the surface of the photovoltaic panel behind the photovoltaic panel, so that the airflow on the surface of each photovoltaic panel behind is fully passed, and the air flow during driving is used to fully blow away the adhesive residue on the surface of the photovoltaic panel, thereby reducing the problem of adhesive residue stains on the surface of the photovoltaic panel.

[0020] 3. The present invention provides a dust-proof mechanism. When the truck stops traveling, the scraper will be pulled back to its original position by the elastic tension of the elastic rope, so that the scraper will scrape off all the fine dust adhered during the traveling process, so as to keep the surface of the photovoltaic panel clean, facilitate the cleanliness of the photovoltaic panel after the subsequent stop and maintain its service life. Moreover, because the scraper is inclined and has an inclined groove at the bottom, after the scraper is pulled back by the elastic rope, when scraping the residual dust on the surface of the photovoltaic panel, the scraped residue will be pushed toward both sides of the scraper through the inclined surface of the outer wall of the scraper, and pushed down to both sides of the photovoltaic panel. As the two sides of the photovoltaic panel fall, the surface of the photovoltaic panel is cleaned and the residue is discharged.

[0021] 4. The present invention provides a dust-proof mechanism. When the scraper is pulled back by the elastic rope, the scraping block on the outer wall of the scraper will be pushed by the hinged plate, so that it slides from the middle to both sides of the scraper along with the outer wall of the scraper, thereby completing the scraping of the outer wall of the inclined groove, and scraping off the stains remaining on the inclined groove when the inclined groove cleans the surface of the photovoltaic panel, thereby completing the multi-directional self-cleaning effect.

[0022] 5. The present invention provides a wind resistance adaptive mechanism, so that when the truck starts to travel, the opening and closing plates and the sliding plates are blown by the wind together, so that the sliding plates are quickly pushed out. After being pushed out, it means that the vehicle speed has reached a faster speed, and the corresponding wind resistance is also large enough. At this time, as the opening and closing plates are tilted back, the wind resistance of the truck during travel is reduced, so that when the sliding plates are blown open by the wind, the wind resistance to the truck is also reduced, and the stability of normal travel is maintained. In other words, for the stability of vehicle travel, opening and closing plates and sliding plates with smaller areas are provided to reduce wind resistance, but the problem that wind force at a higher vehicle speed is required to push the sliding plates to slide and start cleaning work occurs. Therefore, the mechanism adopts an adaptive mode that the wind is attracted over a large area when the wind force is small, and is automatically blown down when the wind force is too large, so as not to affect the stability of the vehicle, and avoids the problem that the sliding plates cannot be pushed by the wind force for scraping and cleaning due to insufficient speed after the vehicle enters the urban area, thereby effectively ensuring the stable progress of the cleaning work.

[0023] 6. The present invention is not only applicable to semi-trailer van-type vehicles, but also to various other van-type trucks and other cargo vehicles. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] Embodiment 1:

[0037] See also Figure 1-3 , the present invention provides a technical solution: a photovoltaic assembly on the roof of a cargo commercial vehicle, comprising a cargo truck 1, a wheel 5 is arranged at the bottom of the cargo truck 1, a cargo box 2 is fixedly connected to the outer wall of the cargo truck 1, a photovoltaic panel 6 is fixedly connected to the top of the cargo box 2, and a dustproof mechanism 3 is arranged on the top of the cargo box 2;

[0038] The dust prevention mechanism 3 comprises:

[0039] The scraper 301 is an inclined plate-shaped structure. The bottom of the scraper 301 is slidably connected to the top of the photovoltaic panel 6. The top of the scraper 301 is fixedly connected with a sliding plate 307. The scraper 301 is used to scrape and clean the surface of the photovoltaic panel 6.

[0040] Fixed block A304, fixed block A304 is a square block structure, the bottom of fixed block A304 is fixedly connected to the top of the cargo box 2, one side of fixed block A304 is fixedly connected to one side of the photovoltaic panel 6, one end of the limit rod 306 is fixedly connected to the outer wall of the fixed block A304, the two sides of the photovoltaic panel 6 are in contact with fixed blocks B, the outer wall of fixed block B305 is fixedly connected to the top of the cargo box 2, and the fixed block A304 is used to play the role of fixing the limit rod 306;

[0041] When the truck 1 is started and driven on the road, the photovoltaic panel 6 on the top of the cargo box 2 generates photovoltaic power through the sun, and when the cargo box 2 is driven together, the sliding plate 307 outside the photovoltaic panel 6 will be blown by the wind, and because the surface of the sliding plate 307 facing the front of the cargo box 2 is an arc-shaped surface, the air will quickly push the sliding plate 307 to slide on the outer wall of the limit rod 306, thereby driving the scraper 301 below to move synchronously, so that when driving, the outer wall of the surface of the photovoltaic panel 6 is automatically scraped by the scraper 301, and the dust particles that have been left on the surface of the photovoltaic panel 6 for a night or a few days are scraped off, thereby ensuring the cleanliness of the surface of the photovoltaic panel 6 during driving, and avoiding the problem that the photovoltaic panel 6 is blocked and affects the effect of solar power generation;

[0042] Embodiment 2:

[0043] See also Figure 1-7 On the basis of the first embodiment, the present invention provides a technical solution: a through groove 308 is provided on the inner wall of the sliding plate 307, a long rod 309 is fixedly connected to the outer walls of the two fixed blocks A304, a limit rod 306 is fixedly connected to the outer wall of the scraper 301, one end of the limit rod 306 is fixedly connected to the outer wall of the fixed block A304, an elastic rope 303 is fixedly connected to the outer wall of the scraper 301, and one end of the elastic rope 303 is fixedly connected to the outer wall of the fixed block A304;

[0044] When the truck 1 is traveling for a long time, the scraper 301 and the sliding plate 307 will be blown by the wind to slide to the fixed block B305, and the wind will keep pushing the sliding plate 307 and discharge it through the through slot 308 opened on the inner wall of the sliding plate 307. The opening direction of the through slot 308 on the inner wall of the sliding plate 307 is inclined downward, so the residue entering the through slot 308 from the front will be discharged from the back of the sliding plate 307, and along with the inclined downward direction of the through slot 308, it will be blown to the lower back of the sliding plate 307, and the blown air will blow to the surface of the photovoltaic panel 6 behind the photovoltaic panel 6, so as to realize the full flow of airflow to the surface of each photovoltaic panel 6 at the back, and use the air flow during driving to fully blow away the adhesive residue on the surface of the photovoltaic panel 6, thereby reducing the problem of adhesive residue stains on the surface of the photovoltaic panel 6;

[0045] At the same time, when the truck 1 stops traveling, the scraper 301 will be pulled back to its original position by the elastic tension of the elastic rope 303, so that the scraper 301 will scrape off all the fine dust adhered during the traveling process, keep the surface of the photovoltaic panel 6 clean, and facilitate the cleanliness of the photovoltaic panel 6 after the subsequent stop and placement, so as to maintain its service life. Moreover, because the scraper 301 is in an inclined shape and has an inclined groove 302 at the bottom, when the scraper 301 is pulled back by the elastic rope 303 and scrapes the residual dust on the surface of the photovoltaic panel 6, the scraped residue will be pushed to both sides of the scraper 301 through the inclined surface of the outer wall of the scraper 301, and pushed to both sides of the photovoltaic panel 6. As the two sides of the photovoltaic panel 6 fall, the surface of the photovoltaic panel 6 is cleaned, and the residue is discharged.

[0046] Embodiment three:

[0047] See also Figure 1-11 On the basis of the first and second embodiments, the present invention provides a technical solution: a wind resistance adaptive mechanism 4 is provided on the outer wall of the long rod 309, the inner wall of the fixed block 401 is fixedly connected to the outer wall of the long rod 309, and a hinged plate 402 is hinged at one end of the fixed block 401.

[0048] An articulated block 403 is hinged at one end of the articulated plate 402 . A scraping block 404 is fixedly connected to the outer wall of the articulated block 403 . The outer wall of the scraping block 404 is slidably connected to the outer wall of the scraper plate 301 .

[0049] The outer wall of the scraper block 404 is slidably connected with a telescopic sleeve 405 , and the outer wall of the telescopic sleeve 405 is slidably connected with the outer wall of the sliding plate 307 .

[0050] The top of the sliding plate 307 is rotatably connected to a rotating shaft 406, the outer wall of the rotating shaft 406 is fixedly connected to an opening and closing plate 407, the outer wall of the opening and closing plate 407 is fixedly connected to a magnetic block B409, the outer wall of the magnetic block B409 contacts a magnetic block A408, and the outer wall of the magnetic block A408 is fixedly connected to the outer wall of the rotating shaft 406.

[0051] The opening and closing plate 407 and the magnetic block A408 are magnetic, and the magnetism of the opening and closing plate 407 and the magnetic block A408 on the opposite side is that opposite poles attract each other.

[0052] The outer wall of the opening and closing plate 407 is fixedly connected with a square plate 410, the outer wall of the square plate 410 is fixedly connected with a spring 411, and one end of the spring 411 is fixedly connected with the outer wall of the scraper 301;

[0053] When the scraper 301 is pulled back by the elastic rope 303, the scraper block 404 on the outer wall of the scraper 301 is pushed by the hinged plate 402, so as to slide from the middle to the two sides of the scraper 301 along with the outer wall of the scraper 301, and the outer wall of the inclined groove 302 is scraped off, and the stains remaining on the surface of the photovoltaic panel 6 when the inclined groove 302 is cleaned are scraped off, so as to achieve a multi-directional self-cleaning effect. The two scraper blocks 404 are pushed by the two hinged plates 402. Since the two hinged plates 402 are at different heights, the two scraper blocks 404 are pushed crosswise to perform the scraping and cleaning work without interfering with each other.

[0054] When the vehicle starts to travel, the wind will not only blow the sliding plate 307, but also the opening and closing plate 407 on the top of the sliding plate 307. When the travel speed reaches a certain level, the wind will blow the sliding plate 307 to make the magnetic block B409 separate from the magnetic attraction of the magnetic block A408. Once the magnetic block B409 separates from the magnetic block A408, the opening and closing plate 407 will be instantly blown back by the wind and squeeze the spring 411 to deform it, causing the opening and closing plate 407 to lose the wind resistance it bears, thereby achieving When the truck 1 starts to travel, the opening and closing plate 407 and the sliding plate 307 are blown by the wind. At this time, due to the large windward area, the sliding plate 307 and the opening and closing plate 407 are quickly pushed out together. After being pushed out, it means that the vehicle has reached a relatively fast speed, and the corresponding wind resistance is also large enough. At this time, as the opening and closing plate 407 is tilted back during travel, the windward area of ​​the opening and closing plate 407 and the sliding plate 307 is greatly reduced, thereby reducing the wind resistance of the truck 1 during travel. The wind resistance of the sliding plate 307 is reduced, and the wind resistance of the truck 1 is reduced after the sliding plate 307 is blown open by the wind, so as to maintain the stability of normal driving. In other words, for the stability of vehicle driving, a relatively small opening and closing plate 407 and a sliding plate 307 are set to reduce the wind resistance. However, the problem that the wind force under a relatively high vehicle speed state is required to push the sliding plate 307 to slide and start cleaning work is encountered. Therefore, the mechanism adopts an adaptive mode that attracts wind over a large area when the wind force is small, and is automatically blown down when the wind force is too large, so as to achieve the problem that the sliding plate 307 cannot be pushed by the wind to perform scraping and cleaning due to insufficient speed after the vehicle enters the urban area without affecting the stability of the vehicle, thereby effectively ensuring the stable progress of the cleaning work. Since the opening and closing plate 407 is always in a stable tilted state due to being blown by the wind, the air flows away through its inclined surface, and the air is guided. Therefore, after the vehicle enters a high-speed stable driving, there will be no eddy current phenomenon around the opening and closing plate 407, and it is in a stable state.

[0055] When the subsequent vehicle stops, the opening and closing plate 407 will rebound back to its original position through the square plate 410 due to the rebound force of the spring 411, and then be magnetically attracted by the magnetic block A408 and the magnetic block B409 to restore the original state, and can be opened and closed again during the next driving.

[0056] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
