Description

Technical Field

[0001] The utility model belongs to the fields of ecological environment engineering technology and photovoltaic technology, and particularly relates to a movable ecological floating bed in photovoltaic equipment. Background Art

[0002] As a clean and renewable energy source, solar energy has the advantages of abundant resources and wide distribution. Photovoltaic technology that utilizes solar energy has developed rapidly. However, land photovoltaic equipment requires the occupation of land resources. With the development of the photovoltaic market, the limiting factor of land resources has become increasingly prominent. The application of water surface photovoltaic technology has broken through the bottleneck of land photovoltaic construction.

[0003] Water-based photovoltaic systems are rows of photovoltaic power stations built on the water surfaces of ponds, lakes, reservoirs, and lakes formed in coal mining subsidence areas. Based on the installation method of the photovoltaic modules, they can be divided into two categories: pile-mounted and floating. The pile-mounted type is mostly used in land-based waters, generally with a depth of approximately 3 meters. Water-based photovoltaic systems improve the overall utilization rate of land and reduce water evaporation. However, photovoltaic equipment is often installed in relatively closed water environments such as ponds and lakes, which can affect the growth of phytoplankton and photosynthetic bacteria in the water, thereby affecting the water's self-purification capacity.

[0004] In recent years, agriculture has promoted photovoltaic water cultivation technology. This technology combines the traditional "water surface photovoltaic" model with the planting of plants with strong purification functions on ecological floating beds to purify water bodies, achieve power generation regulation and protect the water ecological environment. However, there are the following problems:

[0005] Photovoltaic equipment requires regular maintenance and inspection. Waterways are left between adjacent photovoltaic rows for inspection ships to pass through. If ecological floating beds are set in the waterways, the lighting is good and suitable for growing various crops. However, the ecological floating beds need to be moved out of the waterways one by one before maintenance and inspection, and restored to the waterways after maintenance, which is time-consuming and labor-intensive. If the ecological floating beds are set under the photovoltaic equipment, although inspection ships can pass through, due to the strong light-blocking effect of the photovoltaic equipment and the relatively low water temperature, only shade-loving plants can be planted, the planting varieties are single, and the economic benefits are not high. Utility Model Content

DETAILED DESCRIPTION

[0031] See also Figure 1 、 Figure 2 and Figure 3 A movable ecological floating bed in a photovoltaic device includes: a photovoltaic unit 1, a driving source 2 and an ecological floating bed 3.

[0032] Several rows of photovoltaic modules are set on the water surface, each row of photovoltaic modules is provided with at least one set of driving sources 2, and each row of photovoltaic modules is provided with several photovoltaic units 1. The photovoltaic units 1 are movably connected to the ecological floating bed 3. The photovoltaic units 1 include a foundation pile 11 fixedly set on the bottom of the water, with the upper end exposed on the water surface; the support plate 12 is fixedly connected to the foundation pile 11; the rack 13 is slidably installed on the support plate 12; the rack 13 is movably connected to the ecological floating bed 3; the gear 14 is engaged with the rack 13; the output end of the driving source 2 is connected to the gear 14; wherein, the driving source 2 drives the gear 14 to rotate, the gear 14 drives the rack 13 to move, and the rack 13 drives the ecological floating bed 3 to move between the waterway 4 and the photovoltaic unit 1. When in the photovoltaic unit 1, the maintenance ship can pass through the waterway 4.

[0033] Specifically, the photovoltaic unit 1 adopts a water surface fixed type with pile foundations. A waterway 4 for maintenance ships to pass through is provided between adjacent rows of photovoltaic modules. There is a certain distance between the pile foundations 11 of the photovoltaic units 1 in the same row to equip the photovoltaic panels 15. The photovoltaic panels 15 are at a certain distance from the water surface. The support plate 12 is fixedly mounted on the pile foundation 11 through the support frame 16. The driving source 2 is installed on land, and its output end is connected to one or several gears 14 through a transmission shaft 21. For example, one driving source 2 drives several gears 14 at the same time, driving multiple ecological floating beds 3 to work together, saving energy. The driving source 2 is installed on land for easy operation. Preferably, the driving source 2 is a motor. The driving source 2 drives the ecological floating bed 3 to move under the waterway 4 and the photovoltaic panel 15 according to actual needs.

[0034] The movable ecological floating bed 3 in the photovoltaic device of the present invention rationally utilizes the water surface space of the photovoltaic unit 1 fixed on the water surface of the foundation pile. The driving source 2 drives the ecological floating bed 3 to be located under the waterway 4 or the photovoltaic panel 15 according to the scene, such as Figure 3 Normally, the ecological floating bed 3 is on the waterway 4, and the crops on the ecological floating bed 3 are exposed to sunlight, which is beneficial to the production of crops; Figure 2 When the maintenance ship needs to pass through the waterway, the driving source 2 is activated to drive the ecological floating bed to move under the photovoltaic panel 15. Therefore, it is possible to use the ecological floating bed 3 to grow various crops without affecting the passage of the maintenance ship during the subsequent operation and maintenance process, and is no longer limited to growing only shade-loving crops. This not only improves the ecological environment in the water body, but also increases economic benefits.

[0035] See also Figure 4 Furthermore, a slide groove 121 is provided on the support plate 12 , and the rack 13 is slidably arranged in the slide groove 121 .

[0036] See also Figure 4Furthermore, the inner wall of the chute 121 is provided with a dovetail groove 122, and the rack 13 is provided with a dovetail platform 131 that cooperates with the dovetail groove 122. Specifically, the chute 121 and the dovetail groove 122 are arranged along the length of the support plate 12, and the chute 121 and the dovetail groove 122 are connected. With this structure, the rack 13 slides stably and directionally on the support plate 12, while preventing external forces (such as those generated by wind and water impact) from affecting the rack 13 and support plate 12, thus keeping the ecological floating bed 3 stable on the water surface.

[0037] See also Figure 4 Furthermore, the support plate 12 is provided with a stopper 123. To prevent the ecological floating bed 3 from continuing to move under the photovoltaic panel 15 due to the inertia of the gear 14 when the rack 13 drives it, a stopper 123 is provided at the rear end of the support plate 12, so that the ecological floating bed 3 can be accurately moved to a position below the photovoltaic panel 15.

[0038] See also Figure 1 and Figure 6 Furthermore, the ecological floating bed 3 also includes a connecting rod 31, one end of which is connected to the rack 13, and the other end of which is provided with a plurality of branch connecting rods 311, which are movably mounted in the ecological floating bed 3. Specifically, the connecting rod 31 includes a main connecting rod 312 and branch connecting rods 311. The connecting rod 31 is fixedly mounted on the end surface of the rack 13 facing the waterway 4. The main connecting rod 312 is perpendicular to the foundation pile 11. The end surface of the main connecting rod 312 facing the water surface is provided with a plurality of branch connecting rods 311 parallel to the foundation pile 11. The ecological floating bed 3 is provided with through holes 35 that cooperate with the branch connecting rods 311. The branch connecting rods 311 are mounted in the through holes 35. The branch connecting rods 311 are close to the water bottom. Therefore, the ecological floating bed 3 can automatically rise and fall with the water surface using the branch connecting rods 311 as guide rails, and will not cause large displacement due to wind or waves. The ecological floating bed 3 always remains in a relatively fixed position. Preferably, the supporting connecting rod 311 is composed of multiple branch connecting rods 313, and the branch connecting rods 313 are connected by threads, which is convenient for disassembly, thereby facilitating the separation of the supporting connecting rod 311 from the ecological floating bed 3.

[0039] See also Figure 5Furthermore, the ecological floating bed 3 is provided with a planting groove 32 and a drainage hole 33. Specifically, the ecological floating bed 3 adopts the existing technology, and the external dimensions are determined by the distance between the waterway 4 and each row of adjacent foundation piles 11. The ecological floating bed 3 is a floating board made of lightweight material, and a planting groove 32 is provided on the floating board, and the drainage hole 33 connects the planting groove 32 and the water area. The lightweight material is a molded environmentally friendly PE material, and the planting groove 32 is filled with a matrix mixed with coconut fiber, fish nets and the like and soil. The size and spacing of the planting groove 32 on the ecological floating bed 3 are selected and determined according to the different plants planted. The planting of this ecological floating bed 3 is not limited to aquatic plants, and a wide range of crops are planted. Through the absorption and adsorption of plant roots and the degradation of root microorganisms, nitrogen, phosphorus and organic matter in the water body are reduced, thereby effectively repairing the water body.

[0040] See also Figure 1 and Figure 7 Furthermore, the ecological floating beds 3 are equipped with connecting assemblies 34 along the side facing away from the waterway 4, connecting adjacent ecological floating beds 3. The installation of connecting assemblies 34 between the three ecological floating beds increases their strength, not only protecting them from being carried away by wind and waves, but also buffering collisions between them during drastic water level fluctuations. The ecological floating beds 3 in a row are spaced apart and connected by connecting assemblies 34, preventing damage from wave impacts. They also function as a linkage during movement, preventing individual ecological floating beds from becoming stuck in their original positions.

[0041] See also Figure 7 Furthermore, the connection assembly 34 includes a connector 341 and an elastic connector 342. One end of the elastic connector 342 is connected to the connector 341 on one ecological floating bed 3, and the other end of the elastic connector 342 is connected to the connector 341 on another adjacent ecological floating bed 3. Preferably, the connector 341 and the ecological floating bed 3 are integrally formed. The ends of the connector 341 are provided with connection holes, and the elastic connector 342 is hooked into the connection holes to connect the two connectors 341. The elastic connector 342 has a certain buffering and restoring effect, and is suitable for environments with different water flow, wind speed, and water fluctuation, thereby enhancing the applicability of the ecological floating bed 3.

[0042] Due to the adoption of the above technical solution, the utility model has the following advantages: the supporting connecting rod 311 is sleeved in the ecological floating bed 3, so that the ecological floating bed 3 can automatically rise and fall along with the water surface with the supporting connecting rod 311 as a guide rail, and will not produce large displacement due to the action of wind or waves. A connecting assembly 34 is provided between the ecological floating beds 3, and the ecological floating bed 3 is always located in a relatively fixed position, playing a linkage role when moving. The support plate 12 is provided with a slide 121 and a dovetail groove 122, and the driving source 2 stably and directionally drives the ecological floating bed 3, allowing the ecological floating bed 3 to move between the waterway 4 and the water surface below the photovoltaic equipment, and reasonably utilizing the water surface space of the photovoltaic equipment, that is, it does not affect the passage during the operation and maintenance of the later maintenance ship, and uses the ecological floating bed 3 to plant various plants with economic value, with diverse planting quality, to achieve the dual benefits of economy and protection of the water ecological environment.

[0043] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above is only a specific implementation method of the utility model and is not intended to limit the utility model. Any modifications, equivalent replacements and improvements made within the scope of the present utility model should be included in the scope of protection of the present utility model.
