Detailed Description

The technical solution provided by the present invention will be explained in more detail with reference to fig. 1 to 22.

The photovoltaic water collecting system is a sunlight utilization system suitable for desert and partition. The inventor finds that in order to improve the solar energy use efficiency of the photovoltaic water collecting system, the photovoltaic water collecting system can be cleaned regularly to wash away the collected sand and ash layer on the surface of the photovoltaic water collecting system to expose the photovoltaic panel. In desert and gobi areas, if water for cleaning directly drops to the ground, the water resource is wasted.

The inventor finds that, through further research, if the accumulated water on the surface of the photovoltaic water collecting system is collected, the problem is not easy: (1) Gaps exist among the photovoltaic panels of the photovoltaic panel assembly, water on the photovoltaic panels can drip down along the gaps, confluence cannot be formed, and water cannot be effectively gathered and is wasted. (2) At present, each photovoltaic plate of the photovoltaic plate assembly is provided with a frame, the frame is higher than the glass plane of the photovoltaic plate, so that water on the glass plane of the photovoltaic plate is blocked at the position where the water flows through the frame easily to cause a overflowing phenomenon, and even the water can splash out, and the water cannot be effectively collected. (3) The effect of blockking of photovoltaic board lower limb frame makes the unable exhaust of water on the photovoltaic board, and photovoltaic board edge long-term ponding can cause the photovoltaic board lower limb to receive water erosion, and causes the damage of photovoltaic board subassembly, and this part water of not exhausting simultaneously can contain impurity such as dust, can form the appearance in mud belt along the lower limb, and this also can reduce photovoltaic board generating efficiency and damage photovoltaic board subassembly.

The embodiment of the invention provides a photovoltaic water collecting system, which is used for effectively collecting and utilizing photovoltaic clean water, rainwater, snow water and other water, reducing the probability of damage to a photovoltaic panel assembly, and is suitable for large photovoltaic power stations, especially for large photovoltaic power stations in arid areas such as deserts, gobi and desert in China.

Referring to fig. 1, herein, the X direction is a direction away from the photovoltaic panel, and the Y direction is a direction close to the photovoltaic panel.

The photovoltaic water collection system comprises a photovoltaic panel assembly 4, a sealing assembly 2, a water collector 1 and a water reservoir 3. The photovoltaic panel assembly 4 comprises a plurality of photovoltaic panels arranged in an inclined manner with a first gap 5 between two adjacent photovoltaic panels. The seal assembly 2 is mounted at the first gap 5; the water collector 1 is located downstream of the photovoltaic panel assembly 4, the water collector 1 comprising an inner recess 100, the inner recess 100 being open, and the opening of the inner recess 100 facing the photovoltaic panel assembly 4. A water reservoir 3 is located downstream of the water collector 1 to collect water accumulated in the water collector 1.

The photovoltaic panel assemblies 4 comprise one or more photovoltaic panels, and each photovoltaic panel assembly 4 comprises a group of photovoltaic panels arranged from top to bottom, and the number of each group is multiple. In some embodiments, the photovoltaic panel assembly 4 is composed of at least two upper and lower columns of assemblies, which may be two upper and lower columns (photovoltaic panel 401, photovoltaic panel 402), three columns (photovoltaic panel 401, photovoltaic panel 402, photovoltaic panel 403), four columns (photovoltaic panel 401, photovoltaic panel 402, photovoltaic panel 403, photovoltaic panel 404), five columns (photovoltaic panel 401, photovoltaic panel 402, photovoltaic panel 403, photovoltaic panel 404, photovoltaic panel 405), and more.

In fig. 1 to 3, each photovoltaic panel assembly 4 is exemplified by four photovoltaic panels, respectively denoted as photovoltaic panel 401, photovoltaic panel 402, photovoltaic panel 403 and photovoltaic panel 404. The size of each photovoltaic panel is the same, and the contained angle of each photovoltaic panel and ground is alpha, and four photovoltaic panels are arranging to one side.

The photovoltaic water collection system comprises one or more photovoltaic panel assemblies 4. The individual photovoltaic panel assemblies 4 are arranged side by side. As shown in fig. 2. 6 photovoltaic board components 4 constitute a photovoltaic board array, and whole photovoltaic water collecting system includes two photovoltaic board arrays. The two arrays of photovoltaic panels have a second gap 6 between them. The individual photovoltaic panel assemblies 4 are arranged in a row, and the rows of photovoltaic panel assemblies 4 are arranged side by side. And a mounting gap 8 is formed between two adjacent rows of the photovoltaic panel assemblies 4.

With continued reference to fig. 1, in addition to that, the photovoltaic water collection system includes a rack assembly 7. One rack assembly 7 is provided for each array of photovoltaic panels. There is no need to provide a separate rack assembly for each photovoltaic panel assembly 4. Thus, the installation space can be saved, and the installation difficulty can be simplified. One photovoltaic panel array corresponds to one support assembly 7, so the structural dimension of support assembly 7 is bigger, can resist abominable natural environment such as desert, gobi more.

With continued reference to fig. 1, the rack assembly 7 includes a plurality of vertical racks 72, a support 71, and a stiffener 73. The supporting member 71 is a frame structure formed by welding a plurality of rods, for example, to meet the requirements of load bearing and weight reduction. The vertical supports 72 include a plurality of supports of varying lengths. A plurality of vertical supports 72 are arranged in sequence from low to high, and each vertical support 72 is installed on the ground surface by adopting a concrete upright 74. The reinforcing members 73 are arranged obliquely, the reinforcing members 73 are specifically, for example, rods, and the number of the reinforcing members 73 may be plural. One end where at least one reinforcement 73 is present is fixedly connected to the vertical support 72; the other end of the reinforcing member 73 is fixedly coupled to the supporting member 71 to prevent the supporting member 71 from being pressed and deformed by the photovoltaic panel assembly 4. The fixed connection mode can be bolt connection, welding, riveting and the like. A support 71 is located at the top end of each vertical bracket 72, and each photovoltaic panel is mounted to the top surface of the support 71 and supported by the support 71.

Each photovoltaic panel includes a solar collection panel and a bezel at an edge of the solar collection panel. The solar energy collecting panel is used for absorbing sunlight and is a flat plane. If the solar energy collecting panel is covered by impurities and sand, the collecting efficiency of the sunlight is affected. The solar collection panel needs to be periodically cleaned with water. The frame is made of aluminum alloy, for example. The height of the frame is higher than the surface of the photovoltaic panel. That is, for each photovoltaic panel, the middle area is concave, and the edge frame is slightly convex. Each photovoltaic panel assembly 4 has a first gap 5 between two adjacent photovoltaic panels, as shown in fig. 1.

Although each photovoltaic panel is arranged obliquely, the inclination angle is α. The alpha angle value is basically 10-46 degrees in the domestic land range, and is basically 35-45 degrees in the northwest region. However, due to the existence of the border at the edge of the photovoltaic panel, water can be blocked by the border at the edge of the photovoltaic panel and cannot flow downwards continuously. The embodiment of the invention provides a photovoltaic water collecting system, which comprises a sealing assembly 2, wherein the sealing assembly 2 is arranged at a first gap 5 between two adjacent photovoltaic panels of each photovoltaic panel assembly 4, so that the areas except the frame of the two adjacent photovoltaic panels are smoothly transited, and water can automatically flow from the photovoltaic panel positioned at the top 2001a of the photovoltaic panel assembly 4 to the bottom of the photovoltaic panel positioned at the bottommost part under the action of the self weight and then automatically flow into a water collector 1.

A plurality of photovoltaic panel assemblies 4 are arranged together to form a photovoltaic panel array. And a second gap 6 is formed between two adjacent photovoltaic panel arrays. A plurality of photovoltaic panel arrays form a photovoltaic panel matrix. The second gap 6 is of a large size and allows the reservoir 3 to be placed and also for personnel to pass through.

Referring to fig. 1, in some embodiments the collector 1 is arranged inclined with respect to the bottom edge P of the photovoltaic panel assembly 4, the direction of inclination M being towards the photovoltaic panel assembly 4, i.e. the collector 1 is slightly inclined towards the photovoltaic panel assembly 4. The reservoir 3 is located below the lower end of the water collector 1 so that water can flow from the water collector 1 into the reservoir 3 under its own weight.

Referring to fig. 2, in some embodiments, the sump 1 is obliquely arranged along a length direction L of the photovoltaic panel assembly 4, and one end of the sump 1 is lower than the other end of the sump 1, and the water reservoir 3 is located below one end of the sump 1.

In some embodiments, the inclination of the water collector 1 with respect to the bottom edge of the photovoltaic panel assembly 4 is 1% to 2%. Its direction of inclination, i.e. the direction of water collection, is specifically towards the position of the reservoir 3, i.e. the lower end of the water collector 1, near the reservoir 3.

The inclination of inclination = elevation difference/horizontal distance of the water collector 1 × 100% of the water collector 1 is specifically expressed by the following formula: β = h/l × 100%, where β is the inclination of the water collector 1, h is the height difference of the water collector 1, and l is the horizontal distance of the water collector 1.

The collector 1 is suspended and fixed to the back support 71 of the last photovoltaic panel in the lower position of the photovoltaic module with an inclination of declination beta. The specific mounting will be described later.

Referring to fig. 2, as described above, the number of the photovoltaic panel assemblies 4 is plural, the plurality of photovoltaic panel assemblies 4 form a photovoltaic panel array, two adjacent photovoltaic panel arrays are in one group, and two photovoltaic panel arrays of the same group share one water reservoir 3. By adopting the same water receiver 3 shared by two photovoltaic panel arrays, the water of the two photovoltaic panel arrays is collected to one water receiver 3, the quantity of the water receivers 3 is saved, and the water storage quantity of the water receiver 3 is increased.

The inclination directions of the

water collectors

1 and 1 of two adjacent photovoltaic arrays are opposite, and both face to the shared water storage device 3.

With continued reference to fig. 2, in some embodiments, a water reservoir 3 common to two photovoltaic panel assemblies 4 of the same group is located between two adjacent photovoltaic panel assemblies 4. Therefore, the length of the connecting pipeline can be saved, and the structure of the whole photovoltaic water collecting system is more compact.

Referring to fig. 4 and 5, in some embodiments, a sealing assembly 2 is mounted at a first gap 5 between two adjacent photovoltaic panels of each photovoltaic panel assembly 4. The sealing assembly 2 connects all the photovoltaic panels of each photovoltaic panel assembly 4 to form a seamless whole, so that water can automatically flow from the top end a to the bottom end B of the photovoltaic panel assembly 4 under the action of its own weight and then be collected by the collector 1.

Referring to fig. 4 and 5, in some embodiments, the seal assembly 2 includes a mounting portion 2001 and a bridge portion 2002. The mounting portion 2001 is located in the first gap 5 between two adjacent photovoltaic panels. The lap part 2002 is located at the top 2001a of the mounting part 2001, and the two are fixedly connected, and the lap part 2002 comprises a first lap surface 2002a and a second lap surface 2002b. The first lapping surface 2002a is smoothly transited to one of the two adjacent photovoltaic panels, and the second lapping surface 2002b is smoothly transited to the other of the two adjacent photovoltaic panels; the first and

second abutment surfaces

2002a, 2002b transition smoothly.

The sealing assemblies 2 can be arranged independently for each photovoltaic panel assembly 4, or one sealing assembly 2 can be arranged for the first gap 5 in the same transverse (i.e. parallel to the length direction L) direction of one photovoltaic panel array, so that the number of the sealing assemblies 2 can be reduced, and the structural strength of the sealing assemblies 2 can be increased. Alternatively, one sealing assembly 2 is provided for each first gap 5 of each photovoltaic panel assembly 4, which may increase the difficulty of manufacturing the sealing assembly 2. The sealing assembly 2 can also be arranged in the mounting gap 8 between two adjacent photovoltaic panel assemblies 4. The seal assembly 2 has a longitudinal direction parallel to the longitudinal direction of the mounting gap 8.

In some embodiments, the first slits 5 aligned with the same array of photovoltaic panels share a common sealing assembly 2. The length of the sealing member 2 is the same as the length of the array of photovoltaic panels, or the length of the sealing member 2 is slightly longer than the length of the array of photovoltaic panels. The mounting portion 2001 and the bridging portion 2002 of the sealing assembly 2 are integral, and the length of the mounting portion 2001 and the length of the bridging portion 2002 are the same, and both may be equal to the length of the photovoltaic panel array.

Referring to fig. 4, in some embodiments, each photovoltaic panel array has a length of 0.8m to 1.8m, specifically, 0.99m, 1.65m, and the like. In particular, the length of the sealing assembly 2 corresponds to the length of the array of photovoltaic panels, i.e. 1.65m. Referring to fig. 4, the upper surface width of the sealing member 2 is L1+ L2, and the sum thereof is 5.9cm to 7.0cm. The thickness of the sealing component 2 is 0.3 cm-0.7 cm. The width L1 of the mounting portion 2001 is 2.5cm to 3.0cm.

Referring to fig. 4, the overlapping portion 2002 has a wing-shaped structure spreading symmetrically on the upper surface of the mounting portion 2001. The entire upper surface of the overlapping portion 2002 is a smooth curved surface. The two ends of the wing-shaped structure are tail ends with radian structures, the bottom end of each tail end is a smooth plane, the lower surface of each tail end is in smooth transition with the bottom surface of the middle part of the wing-shaped structure through an inclined surface S, and the inclined surface S is matched with the inclined surface of the photovoltaic plate edge frame. With this structure, it is possible to better combine with the frame of the photovoltaic panel to better form the fluid surface, so that the water located on the upper surface of the photovoltaic panel smoothly passes through the surface of the sealing assembly 2 to reach the upper surface of the photovoltaic panel located downstream. For example, referring to any one of fig. 1 to 3, water flows from the photovoltaic panel 401 to the photovoltaic panel 402, the converged water flows from the photovoltaic panel 402 to the photovoltaic panel 403, the converged water flows from the photovoltaic panel 403 to the photovoltaic panel 404, and the converged water flows from the photovoltaic panel 404 to the water collector 1, so that the water on the surface of the photovoltaic panel assembly 4 is efficiently collected.

Referring to fig. 4, in some embodiments, the bottoms of the mounting portions 2001 are provided with protrusions 12 in pairs, and the protrusions 12 are caught at the bottoms of two adjacent photovoltaic panels. The protrusion 12 serves to increase the pressure between the mounting portion 2001 and the side of the photovoltaic panel, so that the sealing assembly 2 is more stably mounted and is less prone to falling. Referring to fig. 8, in some embodiments, each leg 2001b is provided with a projection 12. The two protrusions 12 are symmetrically arranged so that the sealing assembly 2 is securely mounted.

Referring to fig. 1, in some embodiments, each first gap 5 is individually provided with a seal assembly 2. The mounting portion 2001 of the seal assembly 2 includes a top portion 2001a and a leg 2001b. The top 2001a is fixedly connected to the overlapping portion 2002. The legs 2001b are arranged in pairs, fixed to the bottom of the top 2001 a. The legs 2001b have a thickness of 0.4cm to 0.8cm, and the width L2 of the lap portion 2002 of the upper surface of the seal assembly 2 is 1.7cm to 2.0cm. The distance H1 between the inside of the lap portion 2002 of the seal assembly 2 and the end of the leg 2001b is 3.5cm to 3.7cm. Adopt the seal assembly 2 of above-mentioned size, can play the effect of the first clearance 5 between two adjacent photovoltaic boards of sealed well, and seal assembly 2 installation is firm reliable, and seal assembly 2 self structural strength is high, is difficult for appearing phenomenons such as deformation in the use.

The sealing component 2 is made of silica gel or acrylonitrile-butadiene-styrene copolymer ABS profiled bars through an injection molding process.

Referring to fig. 4 and 5, in some embodiments, the seal assembly 2 further comprises a reinforcing rod 13, in particular a metal rod, which is provided with threads at both ends. The reinforcing rod 13 is fitted in the mounting portion 2001 at the middle portion thereof, and both ends of the reinforcing rod 13 protrude out of the mounting portion 2001. The reinforcing rod 13 is detachably connected to the overflow preventing plate 2021.

Referring to fig. 4 and 5, the central solid position of the seal assembly 2 is centrally located with a stiffening rod 13 running longitudinally through the entire seal assembly 2. The stiffener 13 extends along the bottom edge of the photovoltaic panel. The diameter of the reinforcing rod 13 is 1.1 cm-1.4 cm. The reinforcement rod 13 is an integrally formed structure with the seal assembly 2, and the reinforcement rod 13 is a metal rod, for example. The reinforcing rod 13 mainly plays a role in reinforcing and enhancing the hardness, and prevents the sealing assembly 2 from moving due to external force such as expansion with heat and contraction with cold or vibration.

Referring to fig. 5, both ends of the reinforcing rod 13 protrude out of the sealing assembly 2, and the reinforcing rod 13 is integrally formed as a double-headed threaded bolt, specifically, the length of a threaded section of each end of the reinforcing rod 13 is 3cm to 5cm. The reinforcing rod 13 is made of steel.

Referring to fig. 5 to 7, in particular, the photovoltaic water collecting system further includes a fixing member 202, and the fixing member 202 is fixedly connected to one sealing assembly 2 and each of two adjacent photovoltaic panels. One fixture 202 is provided at each end of the photovoltaic panel array. Each of the fixing members 202 fixes one end of the sealing assembly 2.

The fixing member 202 has a flat surface at the side and a through hole 18 at the middle, wherein the through hole 18 is used for extending the threaded section of the two ends of the reinforcing rod 13 of the sealing assembly 2. Specifically, the diameter of the through hole 18 is 1.3 cm-1.6 cm, which is 2 cm-3 mm larger than the diameter of the thread section, so as to reduce the installation difficulty of the thread section.

The fixing member 202 is made of steel. The fixture 202 clamps the sealing assembly 2 and two adjacent photovoltaic panels of the same photovoltaic panel assembly 4 together, and then the stiffener 13 of the sealing assembly 2 and the fixture 202 are bolted. Specifically, the fixing member 202 is provided with a through hole 18, the threaded end of the reinforcing rod 13 passes through the through hole 18 of the fixing member 202, and the reinforcing rod 13 is locked to the fixing member 202 by a washer or a nut.

After the reinforcing rod 13 is protruded through the through hole 18, a washer is mounted on the reinforcing rod 13, and then a nut 20 is mounted. Therefore, the fixing member 202, the sealing assembly 2 and the two photovoltaic panels adjacent to each other in the upper and lower directions can be tightly fixed together by tightening the nut 20, and the sealing assembly 2 is prevented from moving due to external forces such as thermal expansion and cold contraction or vibration.

The height of the anti-overflow plate 2021 is higher than the height of the photovoltaic panel. The first fixing plate 2022 is fixedly connected to the overflow preventing plate 2021. The second fixing plate 2023 is also fixedly connected to the overflow preventing plate 2021. The first fixing plate 2022 and the second fixing plate 2023 are arranged in parallel and spaced; the edges of two adjacent photovoltaic panels are clamped by the first fixing plate 2022 and the second fixing plate 2023.

The overflow preventing plate 2021, the first fixing plate 2022, and the second fixing plate 2023 are flat plates, and the three plates are substantially formed in an inverted F shape. The gap between the first fixing plate 2022 and the second fixing plate 2023 corresponds to the thickness of one photovoltaic panel. The through hole 18 is located on the anti-overflow plate 2021, and the through hole 18 is located between the first fixing plate 2022 and the second fixing plate 2023.

The clamping portion 2001c is bent towards a portion far away from the center of the sealing assembly 2, that is, bent outwards, so that the sealing assembly 2 can be hooked at the bottom of the photovoltaic panel, and therefore the sealing assembly 2 is not prone to shaking in the using process and is more stable and firm.

Specifically, the length of the catch 2001c is 0.7cm to 1.0cm. The clamping portion 2001c can be better buckled with the back side edge of the frame of the photovoltaic panel, so that the function of further fixing the sealing component 2 is achieved. The catch 2001c is provided alternatively to the projection 12 described in the above embodiment, and not at the same time.

According to the technical scheme, water in the whole photovoltaic panel area can be collected efficiently, the sealing component 2 fills the first gap 5 between the adjacent photovoltaic panel assemblies 4 in the upper direction and the lower direction, and therefore the water in the photovoltaic panel area in the upper direction can be collected onto the photovoltaic panel area in the lower direction smoothly and finally collected into the water collector 1. On the other hand, the fixing member 202 not only reinforces the sealing assembly 2, but also prevents water on the photovoltaic panel from overflowing from the corners of the two ends of the photovoltaic panel in the length direction, thereby avoiding water waste. Meanwhile, the sealing assembly 2 and the fixing member 202 are convenient and simple to install, the photovoltaic panel assembly 4 and the structure of the photovoltaic panel assembly 4 do not need to be changed, and the structure of the photovoltaic panel assembly 4 is not influenced.

When the water pressure detection element senses the water pressure, the electromagnetic valve of the water collector and the water inlet electromagnetic valve of the water receiver enter working states, so that the valves are opened, and the collected water can be smoothly collected into the water receiver from the water collector; when the water pressure detection element of the water collector does not sense the water pressure, the water inlet electromagnetic valve of the water collector and the water inlet electromagnetic valve of the water receiver enter a closed state, so that the valves are closed. When the water collecting operation is finished, the electromagnetic valve is automatically closed in time, so that the water in the water storage device can be effectively prevented from evaporating, and foreign matters such as insects, bird droppings and the like can be prevented from entering a pipeline to cause blockage.

In some embodiments, the total water storage device is arranged, so that water in heavy rainfall weather or in frequent photovoltaic cleaning can be effectively collected efficiently, and therefore efficient collection of moisture is achieved, and the total water storage device is arranged in the center of a plurality of photovoltaic assemblies, such as 6-8 photovoltaic assemblies. The main water storage device is connected with the water storage device of each component by a water conveying pipeline.

The main reservoir can be located below the surface of the earth, so that the water level difference can be used to achieve self-flow. It is of course also possible to provide a suction pump inside the main reservoir to assist the water in the water collector 1 to flow towards the reservoir 3.

In some embodiments, the entire intelligent monitoring system is automatically operated by a PLC controller, and automation can be achieved.
