[0002] The advantage of water-based photovoltaic equipment is that it does not occupy ground resources, and can also block sunlight to generate electricity and reduce water evaporation. When existing water-based photovoltaic equipment is set up on the sea surface, the photovoltaic equipment is prone to shaking when encountering waves. At the same time, when the waves hit the photovoltaic equipment, the splashed sea water can easily pass over the floating device and adhere to the surface of the photovoltaic panel, causing the surface of the photovoltaic panel to easily adhere to sea water. The crystals precipitated after the seawater evaporates will affect the power generation efficiency of the photovoltaic panel, and will also corrode the power generation panel and shorten its life.

[0003] At the same time, the waves will carry garbage to the shore, and photovoltaic equipment is usually set up near the shore for the convenience of workers to maintain. The garbage rolled to the shore is easy to accumulate on the photovoltaic equipment, causing garbage to accumulate around the photovoltaic equipment, making it impossible for the garbage to float to the shore with the waves, making the collection of marine garbage more difficult. At the same time, the garbage accumulated on the photovoltaic equipment needs to be cleaned up by staff, which increases the maintenance cost of the photovoltaic equipment. In addition, the garbage is blocked on the sea surface by photovoltaic equipment for a long time, which is easy to affect the ecology. Summary of the invention

[0004] In order to overcome the shortcomings of existing equipment that when blocking waves, the splashed seawater adheres to the surface of the photovoltaic panel, affecting the power generation of the photovoltaic panel and shortening the service life of the photovoltaic panel, and the garbage floating on the sea surface to the equipment increases the labor maintenance cost, and the garbage floating on the sea surface for a long time is likely to affect the ecology, the present invention provides a water photovoltaic equipment with a protective function.

[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] Example 1

[0030] A water photovoltaic device with protective function, such as Figure 1-Figure 4 As shown, there are floating photovoltaic devices;

[0031] It also includes a protective plate 4, a pressure plate 5 and a collecting box 6; the protective plate 4 is detachably connected to the front side of the floating photovoltaic device; the protective plate 4 is arranged to be bent forward to facilitate the dispersion of the impact of the waves; a pressure plate 5 is arranged on the front side of the floating photovoltaic device; a plurality of collecting boxes 6 are arranged on the floating photovoltaic device; the pressure plate 5 is detachably connected to the collecting box 6, and the collecting box 6 is made of a material with a density less than that of water; a detachable cover is arranged in the middle of the collecting box 6; a storage cavity 6001 is arranged in each collecting box 6; a plurality of drain outlets 6002 are opened on the lower side of each collecting box 6; each drain outlet 6002 is communicated with the storage cavity 6001; a water inlet 6003 is opened on the front side of each collecting box 6; each water inlet 6003 is communicated with the adjacent storage cavity 6001 and drain outlet 6002.

[0032] A plurality of plates inclined forward are arranged on the upper side of the pressing plate 5 to block the waves and prevent the waves from directly spreading after rushing to the pressing plate 5, so that most of the impact force of the waves acts on the pressing plate 5, which is convenient for the collection box 6 to sink.

[0033] The protection plate 4 is arranged to be gradually inclined downward from the left and right sides toward the middle.

[0034] A buffer cavity 6004 is provided at the front side of the collection box 6, and the buffer cavity 6004 is provided in a diamond shape.

[0035] A filter is provided on the upper side of each drain outlet 6002 to prevent garbage from being discharged from the drain outlet 6002 and affecting the collection of the garbage.

[0036] The inner bottom of the collecting box 6 is arranged to be gradually inclined downward toward the middle on the left and right sides, guiding water and garbage to flow toward the middle of the collecting box 6, preventing garbage from being blocked at the front side of the collecting box 6 and being unable to be collected, thereby improving the garbage collecting effect of the device.

[0037] The floating photovoltaic device includes a buoy 1, a fixing frame 2 and a photovoltaic panel 3; the fixing frame 2 is fixedly connected to the upper side of the buoy 1; the photovoltaic panel 3 is fixedly connected to the upper side of the fixing frame 2; the buoy 1 is slidably connected to the collecting box 6; the front side of the buoy 1 is fixedly connected to the protective plate 4; the lower front side of the buoy 1 is in contact with the pressure plate 5.

[0038] After the workers place the buoy 1 on the sea, they set up the photovoltaic panel 3 on the buoy 1 through the fixing frame 2. The buoy 1 sinks for a distance due to the gravity of the fixing frame 2 and the photovoltaic panel 3 and then floats stably on the sea surface. The photovoltaic panel 3 can reduce water evaporation and inhibit algae reproduction when set up on the sea surface without occupying ground resources. The collection box 6 located in the buoy 1 is affected by the buoyancy, and the upper side of the collection box 6 is in contact with the buoy 1, and the lower side of the collection box 6 is flush with the sea surface.

[0039] When the photovoltaic panel 3 is working, considering that waves are easily generated when the sea surface is windy, the waves directly hitting the buoy 1 are likely to affect the stability of the buoy 1. At the same time, the seawater splashed by the waves hitting the buoy 1 is likely to adhere to the photovoltaic panel 3. After the seawater is exposed to the sun, it is easy to form salt crystals on the surface of the photovoltaic panel 3, resulting in the deterioration of the power generation effect of the photovoltaic panel 3. At the same time, the salt corrodes the photovoltaic panel 3 and reduces its service life. In order to avoid this phenomenon, when installing the photovoltaic panel 3, the workers first install the protective plate 4 and the pressure plate 5 on the front buoy 1, so that the highest point of the protective plate 4 after installation is higher than the highest point of the buoy 1. When the waves hit the buoy 1 on the front side, the buoy 1 itself shakes and drives the protective plate 4 to shake slightly. In this process, the highest point of the protective plate 4 is always higher than the height of the waves. (It should be noted that when the photovoltaic panel 3 is erected on the sea surface, it is usually after detection and site selection. When the wind blows, the wave height of the waves will not exceed the height of the buoy 1), and then the photovoltaic panel 3 is protected by the protective plate 4, so that after the waves hit the buoy 1, the protective plate 4 blocks the splashed sea water to avoid the problem of splashed sea water adhering to the photovoltaic panel 3, thereby ensuring the normal power generation of the photovoltaic panel 3 and extending the service life of the photovoltaic panel 3. At the same time, the protective plate 4 is set to be bent forward, so that after the waves hit the buoy 1, the protective plate 4 will guide the waves to impact downward, so that the waves will impact downward after hitting the protective plate 4, thereby dispersing the impact force of the waves hitting the buoy 1, avoiding the waves directly hitting the buoy 1 and easily affecting the stability of the buoy 1, and reducing the possibility of the buoy 1 turning over (it should be noted that when the photovoltaic panels 3 are erected on the sea surface, the buoys 1 of adjacent photovoltaic panels 3 are connected by ropes, so that the photovoltaic panels 3 are arranged in a matrix, which improves the stability of the photovoltaic panels 3 erected on the sea surface).

[0040] It is also taken into consideration that the waves will carry the garbage to the shore, and the photovoltaic panels 3 are usually installed near the shore for the convenience of workers' maintenance. When the garbage floats to the shore under the carrying of the waves, the buoy 1 will block the garbage, and it is difficult for the garbage to flow to the shore with the waves. At the same time, after the garbage is blocked by the buoy 1, as the buoy 1 is affected by the waves and shakes, the garbage blocked by the buoy 1 is easy to pass over the buoy 1 and come under the photovoltaic panel 3, making it difficult for workers to clean up the garbage. The garbage is blocked by the buoy 1 and floats on the sea for a long time. After a long time, the garbage accumulates more and more, and the garbage will affect the ecology. In order to avoid this phenomenon, the above-mentioned protective plate 4 is used to make the waves impact downward. At this time, the pressure plate 5 is affected by the downward impact of the waves and sinks. It should be noted that the pressure plate 5 is always under the water surface to prevent the pressure plate 5 from blocking the garbage. At this time, the pressure plate 5 is used The downward pressure drives the front side of the collection box 6 to be subjected to downward pressure. At the same time, since the upper side of the collection box 6 is in contact with the buoy 1, when the front side of the collection box 6 is subjected to force, the back side of the collection box 6 cannot be tilted upward, so that the front side of the collection box 6 is forced to move downward, causing the water inlet 6003 to sink underwater. Since the collection box 6 floats on the sea surface, the storage chamber 6001 is in a waterless state. When the water inlet 6003 sinks underwater, seawater enters the buffer chamber 6004 through the water inlet 6003, and then enters the storage chamber 6001 through the buffer chamber 6004. In this process, the seawater flowing into the storage chamber 6001 drives the garbage into the storage chamber 6001, thereby collecting the garbage carried in the waves and avoiding the garbage from accumulating on the front side of the buoy 1. When the wave impact ends, the collection box 6 uses its own buoyancy to float on the water surface again. Figure 4 As shown, at this time, since the drain outlet 6002 is higher than the water surface, when the garbage is collected in the storage chamber 6001, the inhaled seawater is discharged back into the sea through the drain outlet 6002, so as to avoid excessive seawater accumulation in the collection box 6. When the front side of the collection box 6 sinks into the water next time, the seawater in the collection box 6 is prevented from driving the garbage back to the sea surface, thereby preventing the garbage from being backflowed into the sea. In the above manner, when the waves carry garbage, the garbage is collected in a centralized manner through the collection box 6 to avoid garbage accumulation affecting the ecological environment. In the above process, that is, when the waves impact the protective plate 4, the protective plate 4 is set to gradually tilt downward from the left and right sides to the middle, so that the waves are evenly diverted, and the downward impacting seawater is evenly impacted on the pressure plate 5, so that the pressure plate 5 is evenly stressed, which is convenient for the pressure plate 5 to drive the collection box 6 to sink. At the same time, after the waves are evenly diverted, the garbage carried in the waves is also diverted to the corresponding collection box 6 along with the waves, so as to facilitate guiding the garbage into the collection box 6.

[0041] During the process of seawater pouring into the buffer chamber 6004, the buffer chamber 6004 is set to be in a diamond shape, so that the seawater hits the side wall of the buffer chamber 6004, thereby buffering the seawater, preventing the seawater from directly hitting the inner wall of the collection box 6 and causing a large impact, thereby causing the seawater to recoil and carry the garbage out of the storage chamber 6001, thereby preventing the garbage from being rolled back into the sea. At the same time, the cover plate set in the middle of the collection box 6 allows workers to clean the garbage collected in the storage chamber 6001 by simply opening the cover plate in the middle of the collection box 6.

[0042] Example 2

[0043] On the basis of Example 1, Figure 5 and Figure 6 As shown, a rotating plate 101 is also included; a plurality of rotating plates 101 are rotatably connected to the lower side of each collecting box 6, and each rotating plate 101 is made of a material with a density less than that of water; each rotating plate 101 is located in an adjacent drain port 6002.

[0044] It also includes a blocking rod 102; each collecting box 6 is rotatably connected to a plurality of blocking rods 102; each blocking rod 102 is located in the storage cavity 6001; each blocking rod 102 is set to be able to rotate only toward the rear side.

[0045] The front side of each baffle 102 is set to be flat, which increases the force-bearing area of ​​the baffle 102, making it easy for seawater entering the storage chamber 6001 to push the baffle 102 to rotate, thereby preventing seawater and garbage from pushing the baffle 102 and affecting garbage collection.

[0046] When the pressure plate 5 drives the collection box 6 to sink, since the drain port 6002 enters the water from the water surface, when the seawater carrying garbage enters the collection box 6 through the water inlet 6003, the seawater pouring into the collection box 6 from the drain port 6002 will collide with the seawater entering the collection box 6 from the water inlet 6003, thereby affecting the seawater carrying garbage entering the collection box 6 through the water inlet 6003 and affecting the garbage collection. In order to avoid this phenomenon, when the collection box 6 sinks, the rotating plate 101 contacts the sea surface and rotates counterclockwise based on the view from the front to the back, and then overlaps the inside of the collection box 6, such as Figure 5 As shown, when the collecting box 6 continues to sink, the drain port 6002 is closed by the rotating plate 101, so that seawater only enters from the water inlet 6003, and the garbage is carried into the middle of the storage chamber 6001 by the seawater. When the collecting box 6 floats up and resets, the rotating plate 101 gradually separates from the sea surface, so that the rotating plate 101 rotates clockwise to open the drain port 6002, and then the water in the storage chamber 6001 is discharged, so as to avoid seawater from pouring into the collecting box 6 from the drain port 6002 when the seawater carries the garbage into the collecting box 6, thereby preventing the seawater from affecting the garbage from passing into the collecting box 6 and being collected.

[0047] In the above process, when the garbage is pushed toward the collection box 6, it passes through the baffle rod 102. At this time, the baffle rod 102 is impacted by the seawater and the garbage. From the right to the left, all the baffle rods 102 rotate counterclockwise, so that the garbage and seawater pass over the baffle rod 102 and enter the middle of the collection box 6. When the seawater flows back to the water inlet 6003, the baffle rod 102 is as shown in the figure. Figure 6 As shown, it cannot rotate, thereby intercepting the garbage, so that the garbage cannot be carried out of the collection box 6, and the garbage is stably stored in the middle of the collection box 6, thereby improving the storage capacity of the equipment for garbage.

[0048] Example 3

[0049] On the basis of Examples 1 and 2, Figure 1 and Figure 7 As shown, it also includes a pendulum bar 201; a plurality of pendulum bars 201 are arranged on the upper side of the pressure plate 5, and the pendulum bars 201 are made of elastic deformable material; the upper side of each pendulum bar 201 is lower than the sea surface.

[0050] During the process of collecting garbage in the collection box 6, when the waves are guided by the protective plate 4 to impact the left and right sides, the garbage is first dispersed by the impact force of the waves hitting the protective plate 4. At the same time, the impact force generated by the waves hitting the protective plate 4 also synchronously drives the pendulum bar 201 to swing. The pendulum bar 201 scatters the dispersed garbage, making it easier for the garbage to enter the storage chamber 6001 through the water inlet 6003 for collection.
