Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic construction technology, and in particular relates to a rainwater collection and drip irrigation device between photovoltaic panels. Background Technology

[0002] Photovoltaic power plants have relatively low development costs and short construction periods. However, they occupy a large area and cause significant ecological disturbance to the local ecosystem during construction and operation. This is especially true in desert and barren areas where the ecosystem is extremely fragile. Construction and operation inevitably cause some damage to vegetation. Therefore, ecological vegetation restoration is included in the construction of photovoltaic power generation projects.

[0003] Ecological vegetation restoration in photovoltaic power generation projects generally involves planting trees and shrubs and sowing grass seeds. Under the photovoltaic panels, shrubs are mostly planted and grass seeds are sown. However, due to the shading of the top photovoltaic modules, rain cannot effectively cover the shrubs and grasses below, which often results in lower growth and survival rates of shrubs and grasses under the photovoltaic modules compared to those between the photovoltaic strings.

[0004] Therefore, there is an urgent need for a rainwater collection and drip irrigation device between photovoltaic panels. Utility Model Content

[0005] The purpose of this invention is to provide a rainwater collection and drip irrigation device between photovoltaic panels to solve the problems existing in the background technology.

[0006] The objective of this utility model is achieved through the following technical solution: A rainwater collection and drip irrigation device between photovoltaic panels includes a slot assembly and a dripping assembly. The slot assembly is engaged in the lateral gap between adjacent photovoltaic panels and includes a lateral slot and a hole located below the lateral slot. The dripping assembly is fixed below the hole and includes a hose and a flow regulator located in the middle of the hose.

[0007] Furthermore, the horizontal slot overlaps the edges of two adjacent photovoltaic panels on both sides in the vertical direction, the horizontal slot is sealed on both sides in the horizontal direction, and an opening is provided below the horizontal slot corresponding to the position of the slot. The slot has a funnel-shaped structure that is larger at the top and smaller at the bottom, and the slot is connected to the horizontal slot as a whole.

[0008] Furthermore, a filter is provided between the perforated groove and the hose. The filter has an inverted S-shaped structure and includes a sedimentation section and a filtration section. One end of the sedimentation section is connected to the lower part of the perforated groove, and one end of the filtration section is connected to the hose.

[0009] Furthermore, the lower end of the sedimentation section is provided with a sludge discharge port, and the filtration section is provided with activated carbon particles and a filter membrane.

[0010] Furthermore, a water receiving box is provided at the bottom of the photovoltaic panel, and the water receiving box is fixed to the support frame below the photovoltaic panel by a connecting rod.

[0011] Furthermore, the water receiving box has a downward tilted structure, and multiple dripping components are provided at the lowest end of the water receiving box.

[0012] The beneficial effects of this utility model are: After rainwater washes over the photovoltaic panels, it flows into the horizontal slots of the card slot assembly, and then flows through the holes into the hose below. The flow rate of the hose is adjusted by the flow regulator according to the specific production situation of the plants under the photovoltaic panels. For shrubs and trees that do not need watering, the flow regulator is turned off in time to achieve the purpose of precise irrigation.

[0013] The flow regulator in the middle of the hose uses a mechanical structure to change the cross-sectional area of ​​the hose, thereby adjusting the liquid flow resistance to control the flow rate and thus achieving precise irrigation.

[0014] The rainwater entering the hose is first settled by the filter and then filtered through activated carbon particles and a filter membrane, making the rainwater cleaner and preventing excessive impurities in the rainwater from clogging the hose.

[0015] Rainwater can be effectively collected through the water collection box. At the same time, to avoid over-irrigating the plants below the lowest point of the photovoltaic panel, multiple sets of drip irrigation components distribute excess rainwater to plants in other locations.

Detailed Implementation

[0017] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0018] like Figures 1-3 As shown, a rainwater collection and drip irrigation device between photovoltaic panels includes a slot assembly 2 and a dripping assembly 3. The slot assembly 2 is engaged in the lateral gap between adjacent photovoltaic panels 1. The slot assembly 2 includes a lateral slot 21 and a hole slot 22 located below the lateral slot 21. The dripping assembly 3 is fixed below the hole slot 22. The dripping assembly 3 includes a hose 31 and a flow regulator 32 located in the middle of the hose 31.

[0019] Through the above technical solution, during natural precipitation, due to the inclined arrangement of photovoltaic panel 1, rainwater flows into the horizontal slot 21 of slot assembly 2 after washing photovoltaic panel 1, and then flows into the lower hose 31 through the hole slot 22. According to the specific production situation of the plant under photovoltaic panel 1, the flow rate of hose 31 is adjusted by flow regulator 32. For shrubs and grasses that do not need watering, the flow regulator 32 is turned off in time to achieve the purpose of precise irrigation.

[0020] Specifically, Figure 3 As shown, photovoltaic panels 1 are evenly arranged to form photovoltaic strings. The total length of the horizontal slots 21 is adapted to the length of the photovoltaic strings, and the horizontal slots 21 are engaged in the horizontal gaps of the photovoltaic panels 1. Figure 1 As shown, the cross-section of the transverse slot 21 is U-shaped, and the two ends of the U-shape are provided with overlapping plates to overlap the transverse slot 21 with the edges of two adjacent photovoltaic panels 1. The transverse slot 21 is sealed on both sides in the horizontal direction, so that rainwater collects in the transverse slot 21.

[0021] Furthermore, for ease of removal and unloading, a horizontal slot 21 is set according to the width of the four photovoltaic panels 1. The horizontal slot 21 is made of 1mm white iron sheet. The horizontal slot 21 is easy to remove for cleaning through the overlapping installation method.

[0022] A hole is provided below the horizontal slot 21 at the position corresponding to the slot 22. The slot 22 is fixed to the horizontal slot 21 by welding, and the horizontal slot 21 and the slot 22 are connected. Figure 2 As shown, the groove 22 has a funnel-shaped structure that is larger at the top and smaller at the bottom, which facilitates the connection of the thinner hose 31 at the bottom to the lower end of the groove 22. The hose 31 can be tied to the lower end of the groove 22 by means of rubber bands, steel wires, etc.

[0023] Continue as Figure 1 As shown, the hose 31 is long enough to reach the plant roots. The flow regulator 32 in the middle of the hose 31 changes the cross-sectional area of ​​the hose 31 through a mechanical structure, thereby adjusting the liquid flow resistance to control the flow rate and thus achieving precise irrigation. Example

[0024] Based on Example 1, see [link / reference] Figure 4 A filter 4 is provided between the perforated groove 22 and the hose 31. The filter 4 has an inverted S-shaped structure and includes a sedimentation section 41 and a filtration section 42. One end of the sedimentation section 41 is connected to the lower part of the perforated groove 22, and one end of the filtration section 42 is connected to the hose 31. Activated carbon particles and a filter membrane are provided inside the filtration section 42.

[0025] Through the above technical solution, when rainwater washes over the photovoltaic panel 1, it carries the mud and sand on the photovoltaic panel 1 into the horizontal slot 21. At this time, the mud and water enter the filter 4 through the perforated slot 22. Since the filter 4 includes a sedimentation section 41 and a filtration section 42, the mud and water will first settle in the sedimentation section 41. As the mud and water gradually increase, the settled rainwater then enters the hose 31 through the filtration section 42. At this time, the rainwater entering the hose 31 first settles and then is filtered by activated carbon particles and a filter membrane, making the rainwater cleaner and avoiding excessive impurities in the rainwater that could clog the hose 31, thus effectively improving the irrigation effect.

[0026] Furthermore, the lower end of the sedimentation section 41 is provided with a mud discharge port 43, through which mud and water in the sedimentation section 41 can be discharged to avoid excessive accumulation of mud and water in the filter 4. At the same time, when cleaning the photovoltaic panel 1, the mud discharge port 43 is opened, and after multiple rinsings, impurities in the transverse slot 21, the hole slot 22 and the sedimentation section 41 can be discharged.

[0027] Furthermore, a water collection box 5 is provided at the bottom of the photovoltaic panel 1, and the water collection box 5 is fixed to the support frame below the photovoltaic panel 1 by a connecting rod. The water collection box 5 has a downward inclined structure, and multiple sets of dripping components 3 are provided at the lowest end of the water collection box 5.

[0028] With the above technical solution, since the photovoltaic panel 1 is arranged at an angle downwards, a large amount of rainwater tends to collect at the bottom of the photovoltaic panel 1. The rainwater can be effectively collected by the water collection box 5. At the same time, in order to avoid over-irrigation of the plants below the bottom of the photovoltaic panel 1, multiple sets of drip irrigation components 3 are used to distribute excess rainwater to plants in other locations.

[0029] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
