Description

Technical Field

[0001] The present invention relates to an irrigation system, specifically a photovoltaic panel intensive water use irrigation system for desert ecological management, belonging to the technical field of desert ecological management. Background Art

[0002] Due to the unique geographical location, arid climate and frequent sand activities in desert areas, desertification has seriously threatened the human living environment and the development of social economy. Desertification not only causes the imbalance of the ecological system, but also continuously reduces the arable land area. Therefore, effectively managing deserts and desertified areas and suppressing the expansion of deserts are important contents of current ecological construction. Traditional management measures such as enclosure and conservation, artificial afforestation, and sand fixation nets have large engineering quantities, high investment, and general effects. To better manage the desert environment through afforestation or planting forage grass, the management method of afforestation or planting forage grass requires watering of trees or forage grass to ensure that the trees or forage grass can maintain growth. In order to further utilize the terminal resources in the desert, solar photovoltaic power generation panels will be erected in the afforestation area. The sand control mode combining photovoltaic with special forage grass can reduce the effects of wind and sand erosion, fertilize the land, and reduce dust. It is beneficial to photovoltaic power generation and can also improve the ecological environment. However, wind and sand will cause sand accumulation and dust flying in the photovoltaic power generation area, reducing the power generation efficiency and polluting the environment. Therefore, in order to better achieve the photovoltaic power generation effect, the photovoltaic panels need to be cleaned regularly. The water used for cleaning the photovoltaic panels can be further utilized to water trees or forage grass, etc.

[0003] In the prior art, as disclosed in the photovoltaic panel surface cleaning device based on reciprocating rotation with the publication number CN118174639A, by setting a cleaning mechanism, when the moving frame moves, it can drive the cleaning brush to move, cleaning the stains on the surface of the photovoltaic panel. At the same time, the cleaning brush itself is also rotating, more efficiently cleaning the stubborn stains on the surface of the photovoltaic panel. After the cleaning brush finishes cleaning, the moving frame rotates after moving away from the photovoltaic panel, driving the sponge strip to move towards the photovoltaic panel, re-cleaning the places on the photovoltaic panel that have been cleaned by the cleaning brush, and sucking up the remaining cleaning water stains, so that there will be no water stains remaining on the photovoltaic panel, affecting the use of the photovoltaic panel. And the cleaning mechanism can adapt to different angles of the rotating photovoltaic panel and clean it. Although the prior art involves the cleaning of photovoltaic panels, in practice, firstly, the prior art uses the rolling of the cleaning brush to clean the sundries on the surface of the photovoltaic panel. After cleaning the photovoltaic panel in this way, some impurities will adhere to the used cleaning brush or sponge strip. For example, for a photovoltaic panel in a fan-shaped environment, since the main accumulation on the surface of the photovoltaic panel is sand, it is easy to adhere to the cleaning brush, which will cause scratches and incomplete cleaning on the surface of the photovoltaic panel after long-term use. That is, there are many drawbacks in the existing cleaning method, and the cleaning brush is easily worn, and long-term cleaning outdoors cannot be achieved. Secondly, there is no reasonable reuse of the generated cleaning water. When it rains, a certain amount of rainwater will also be collected on the upper surface of the photovoltaic panel. If the cleaning water and part of the rainwater can be collected and utilized, it can achieve the purpose of better saving water resources. And the photovoltaic panel is installed in an open area outdoors, so some plants will be planted in the installation area of the photovoltaic panel. The prior art only focuses on cleaning the photovoltaic panel and fails to combine the photovoltaic panel with the surrounding planting environment and cannot play a role in improving the environment.

[0019] Embodiment 1 AsFigure 1 , Figure 4 and Figure 10 As shown, a photovoltaic panel intensive water-saving irrigation system for desert ecological management includes a photovoltaic panel 1, a cleaning component 3, and a recycling irrigation component. The photovoltaic panel 1 is inclined. The cleaning component 3 is arranged at the inclined upper end of the photovoltaic panel 1. The recycling end of the recycling irrigation component is communicated with the cleaning end of the cleaning component 3. The cleaning component 3 includes a fixed cleaning pipe 31 and a movable cleaning pipe 32. The recycling irrigation component includes a water storage pipe 5, a recycling pipeline unit, and an irrigation pipeline unit. The upper surface of the photovoltaic panel 1 can be cleaned by the cleaning component to clean dust and other sundries on the surface of the photovoltaic panel 1. It can avoid the blockage caused by sundries on the surface of the photovoltaic panel 1, that is, avoid the reduction of the photovoltaic power generation efficiency of the photovoltaic panel 1. Secondly, the set recycling irrigation component collects the water used for cleaning into the water storage pipe 5 through the recycling pipeline unit, and transports the water in the water storage pipe 5 to the plants planted around the photovoltaic panel 1 through the irrigation pipeline unit for irrigation, so as to provide better water application conditions for the plants planted around the installation position of the photovoltaic panel 1. It can realize the cleaning of the photovoltaic panel 1 and further collect and reuse the cleaning water and rainwater, greatly improving the utilization efficiency of water resources. It can be applied to water-scarce areas such as deserts. While generating electricity through the photovoltaic panel 1, it can also realize the management of the surrounding environment, making solar power generation and ecological management complement each other's weaknesses, and achieving multiple ecological benefits such as land improvement, sand fixation and land reclamation, wind and sand control, and vegetation restoration while generating electricity. It can also provide high-quality forage, promote the development of animal husbandry, and improve economic and ecological benefits; The fixed cleaning pipe 31 and the movable cleaning pipe 32 are distributed in a vertically offset manner. The fixed cleaning pipe 31 is parallel to the inclined upper edge of the photovoltaic panel 1. The movable cleaning pipe 32 moves horizontally along the inclined upper edge of the photovoltaic panel 1, and the movable cleaning pipe 32 is parallel to the inclined plate body of the photovoltaic panel 1. Fixed cleaning nozzles 314 are provided on the pipe body of the fixed cleaning pipe 31, and movable cleaning nozzles 315 are provided on the pipe body of the movable cleaning pipe 32. When cleaning the photovoltaic panel 1, the movement of the movable cleaning pipe 32 can comprehensively wash and clean the surface of the photovoltaic panel 1. The caked and hardened surface dust can also be moistened and softened, and then rinsed from the inclined upper end of the photovoltaic panel 1 through the fixed cleaning pipe 31, so that the moistened and softened surface dust flows to the bottom end of the photovoltaic panel 1 along the rinsing water flow. By repeatedly using the movable cleaning pipe 32 to moisten and soften the surface dust and using the inclined rinsing of the fixed cleaning pipe 31, thorough cleaning of the photovoltaic panel 1 is achieved. The recovery pipeline unit of the recovery and irrigation assembly includes a recovery pipe 54 and a backwash filter 55. The recovery pipe 54 is connected between the backwash filter 55 and the bottom end of the photovoltaic panel 1. A return pipe 56 is connected between the backwash filter 55 and the water storage pipe 5. The irrigation pipeline unit of the recovery and irrigation assembly includes a sprinkler pipe 4 and a drip irrigation plate 6. The sprinkler pipe 4 is laid on the ground in the installation area of the photovoltaic panel 1, and the drip irrigation plate 6 is connected below the photovoltaic panel 1. The backwash filter 55 can filter the recovered cleaning water or rainwater and then transport it to the water storage pipe 5. The water in the water storage pipe 5 can be used to sprinkle the plants planted around the photovoltaic panel 1 through the sprinkler pipe 4, and can drip irrigate the plants planted directly below the photovoltaic panel 1 through the drip irrigation plate 6, that is, the collection of cleaning water or rainwater can be realized, and at the same time, the water can be more evenly sprayed on the plants planted around the photovoltaic panel 1 to achieve precise irrigation.

[0020] Embodiment 2 Improved on the basis of Embodiment 1: As Figures 1 to 3 shown, an outer frame plate 2 is provided around the photovoltaic panel 1. A photovoltaic panel support frame 23 is connected in the inner frame area of the outer frame plate 2, and the photovoltaic panel 1 is placed on the photovoltaic panel support frame 23 in the inner frame area of the outer frame plate 2. A U-shaped drainage groove 24 is provided on the plate body of the outer frame plate 2, and the drainage groove 24 is located on both sides and the bottom edge of the photovoltaic panel 1. The drainage groove 24 at the bottom edge of the photovoltaic panel 1 is connected to the recovery pipe 54, so that the photovoltaic panel 1 and the outer frame plate 2 can be combined together, and then the cleaning water or rainwater can flow downward along the inclined surface of the photovoltaic panel 1 to be collected by the drainage groove 24. When the movable cleaning pipe 32 comprehensively flushes and cleans the photovoltaic panel 1, the cleaning water sprayed when the movable cleaning pipe 32 moves to both sides can also be collected by the drainage groove 24 and can converge to the bottom edge of the drainage groove 24 for recovery, realizing the maximum collection of the cleaning water or rainwater on the surface of the photovoltaic panel 1.

[0021] Further, one side wall of the drainage groove 24 close to the side of the photovoltaic panel 1 is provided with a water guiding inclined surface 25, and a filter screen 22 is clamped on the drainage groove 24. By providing the filter screen 22, the inner space of the drainage groove 24 can be blocked, so that larger sundries such as leaves or weeds can be prevented from falling into the groove, avoiding affecting the normal drainage of the drainage groove 24. At the same time, due to the provision of the water guiding inclined surface 25, when the filter screen 22 is clamped at the opening part at the upper end of the drainage groove 24, a certain gap will be left between the filter screen 22 and the water guiding inclined surface 25, so that the cleaning water or rainwater can flow into the groove along the gap.

[0022] As Figure 1 , Figures 4 to 9 shown, the cleaning assembly 3 further includes a U-shaped frame 33, a threaded rotating rod 34 and a slider 35. The U-shaped frame 33 is fixedly connected to the inclined upper edge of the outer frame plate 2. Rotating bearings 37 are embedded at both ends of the U-shaped frame 33. The two ends of the threaded rotating rod 34 penetrate through the rotating bearings 37. A slider 35 is threadedly connected to the rod body of the threaded rotating rod 34 between the two ends of the U-shaped frame 33. The inclined upper end of the movable cleaning pipe 32 is fixedly connected to the slider 35. By rotating the threaded rotating rod 34, the slider 35 can be moved, so as to drive the movable cleaning pipe 32 to horizontally move along the inclined upper edge of the photovoltaic panel 1, so as to comprehensively wash and clean the upper surface of the photovoltaic panel 1.

[0023] Furthermore, a forward water turbine 38 and a reverse water turbine 39 are respectively arranged on both sides of the U-shaped frame 33. The rotating water wheels of the forward water turbine 38 and the reverse water turbine 39 are coaxially connected to both ends of the threaded rotating rod 34. The output end of the forward water turbine 38 is communicated with the fixed cleaning pipe 31. The output end of the reverse water turbine 39 is communicated with a connecting hose 310, and the other end of the connecting hose 310 is communicated with the movable cleaning pipe 32. The input end of the forward water turbine 38 is communicated with a fixed cleaning water supply pipe 311. The input end of the reverse water turbine 39 is communicated with a movable cleaning water supply pipe 312. A three-way pipe 313 is communicated between the fixed cleaning water supply pipe 311 and the movable cleaning water supply pipe 312, and the three-way pipe 313 is communicated with the irrigation pipeline unit of the recycling irrigation assembly. An electromagnetic three-way valve 316 is installed on the pipe body of the three-way pipe 313. The inner side walls of both ends of the U-shaped frame 33 are connected with limit switches 36. Both the electromagnetic three-way valve 316 and the limit switches 36 are in signal transmission connection with the peripheral terminal. In the initial state, water can be supplied to the fixed cleaning water supply pipe 311 or the movable cleaning water supply pipe 312 through any open passage of the electromagnetic three-way valve 316. If water is first supplied to the fixed cleaning water supply pipe 311, when the water is conveyed into the fixed cleaning water supply pipe 311, it can drive the rotating water wheel in the forward water turbine 38 to rotate forward, and then drive the threaded rotating rod 34 to rotate forward, so as to drive the slider 35 to move in one direction. When moving to the end point, the slider 35 will touch the limit switch 36 at this end point. At this time, the electromagnetic three-way valve 316 will be controlled to switch the passage and supply water to the movable cleaning water supply pipe 312. When the water is conveyed into the movable cleaning pipe 32, it can drive the rotating water wheel in the reverse water turbine 39 to rotate reversely, and then drive the threaded rotating rod 34 to rotate reversely, so as to drive the slider 35 to move in the other direction. At the same time, when the movable cleaning pipe 32 moves, it can also spray the surface of the photovoltaic panel 1. When moving to the end point, the slider 35 will touch the limit switch 36 at this end point, and the above process can be repeated. Through the intermittent cleaning and flushing of the fixed cleaning pipe 31 and the movable cleaning pipe 32, the photovoltaic panel 1 can be thoroughly cleaned.

[0024] As Figure 1 and Figure 10 shown, the sprinkler pipe 4 is arranged in a cross shape, and a number of sprinkler nozzles 41 are opened on the pipe body of the sprinkler pipe 4. The surrounding plants of the photovoltaic panel can be evenly sprinkled through the number of sprinkler nozzles 41 communicated with the sprinkler pipe 4, so as to expand the sprinkling range, provide the water required for plant growth, and promote the growth of plants.

[0025] Further, a fixed sleeve 42 is welded at the connecting part of the vertical and horizontal pipe bodies of the sprinkler pipe 4. The opening end of the fixed sleeve 42 faces vertically upward.

Support rods 21 are vertically connected to the four corners of the outer frame plate 2, and the bottom ends of the support rods 21 are fixedly inserted into the fixed sleeve 42. By using the cross-shaped sprinkler pipe 4 as the bottom support structure for supporting the photovoltaic panel 1, on the one hand, while the sprinkler pipe 4 can play the role of sprinkler irrigation, the stability of the installation of the photovoltaic panel 1 can be improved due to the large area supported by the sprinkler pipe 4. On the other hand, if the photovoltaic panel 1 is removed, the sprinkler pipe 4 can also be left in place to continue playing the role of sprinkler irrigation, realizing disassembly and reuse.

Both the drip irrigation water pump 59 and the sprinkler water pump 53 are electrically connected to an external power supply. The water in the water storage pipe 5 can be pumped out by the sprinkler water pump 53 and conveyed to the fixed cleaning pipe 31 or the movable cleaning pipe 32 through the cleaning water supply pipe 51 to clean the surface of the photovoltaic panel 1, and the water can also be conveyed to the sprinkler pipe 4 through the sprinkler water supply pipe 52 to irrigate the plants planted around the photovoltaic panel 1. The water in the water storage pipe 5 can also be pumped out by the drip irrigation water pump 59, conveyed to the backwash filter 55 through the backwash water delivery pipe 57, and then conveyed to the drip irrigation cavity 61 of the drip irrigation plate 6 through the drip irrigation water supply pipe 58 and dripped through the drip irrigation holes 62, that is, drip irrigation of the plants directly below the photovoltaic panel 1 can be realized.

[0027] Further, solenoid valves 7 are installed on the pipe bodies of the cleaning water supply pipe 51 and the sprinkler irrigation water supply pipe 52, and the solenoid valves 7 are in signal transmission connection with an external control terminal, and can respectively control the opening and closing of the cleaning water supply pipe 51 or the sprinkler irrigation water supply pipe 52, so that the cleaning function or the sprinkler irrigation function or both can be selected according to specific usage requirements.

[0028] Further, a filter plate 510 and an arc-shaped baffle 511 are arranged in the backwash filter 55. The filter plate 510 is horizontally connected in the backwash filter 55. A plurality of arc-shaped baffles 511 are provided. The arc-shaped baffles 511 are connected to the inner wall of the backwash filter 55, and the arc-shaped baffles 511 are located directly above the filter plate 510. The recovery pipe 54 communicates with the top of the backwash filter 55, the backwash water supply pipe 57 communicates with the bottom of the backwash filter 55, and the drip irrigation water supply pipe 58 communicates with the side wall of the backwash filter 55. The connection position of the drip irrigation water supply pipe 58 on the side wall of the backwash filter 55 is above the installation position of the filter plate 510. When cleaning water or rainwater is recovered, the water entering the backwash filter 55 through the recovery pipe 54 can be filtered by the filter plate 510 and then collected in the water storage pipe 5. When the drip irrigation water pump 59 pumps the water in the water storage pipe 5 and transports it to the backwash filter 55 through the backwash water supply pipe 57, the water flow flows upward from the bottom of the backwash filter 55, and the upward flowing water flow can be turned over under the action of the arc-shaped baffle 511 to ensure that the impurities on the filter plate 510 are completely stirred up, so that the impurities on the filter plate 510 can be taken out and discharged by dripping through the drip irrigation holes 62, that is, the filter plate 510 can be backwashed while drip-irrigating the planted plants, so as to prevent impurities from accumulating on the filter plate 510.

[0029] Working principle: The upper surface of the photovoltaic panel 1 is cleaned by a cleaning component. The movement of the movable cleaning pipe 32 can comprehensively flush and clean the surface of the photovoltaic panel 1. The caked and hardened surface dust can also be wetted and softened, and then it is rinsed from the inclined upper end of the photovoltaic panel 1 through the fixed cleaning pipe 31, so that the wetted and softened surface dust flows to the bottom end of the photovoltaic panel 1 along the rinsing water flow. By repeatedly wetting and softening the surface dust with the movable cleaning pipe 32 and rinsing it obliquely with the fixed cleaning pipe 31, thorough cleaning of the photovoltaic panel 1 is achieved, which can prevent sundries from blocking on the surface of the photovoltaic panel 1, that is, prevent the reduction of the power generation efficiency of the photovoltaic panel 1. Secondly, a sprinkler pipe 4 is laid on the ground in the installation area of the photovoltaic panel 1, and a drip irrigation plate 6 is connected below the photovoltaic panel 1. The recycled cleaning water or rainwater can be filtered by the backflush filter 55 and then conveyed to the water storage pipe 5. The water in the water storage pipe 5 can be used to sprinkle the plants planted around the photovoltaic panel 1 through the sprinkler pipe 4, and can drip irrigate the plants planted directly below the photovoltaic panel 1 through the drip irrigation plate 6. That is, the collection of cleaning water or rainwater can be realized, and at the same time, the water can be more evenly sprayed on the plants planted around the photovoltaic panel 1 to achieve precise irrigation. It can be used in water-scarce areas such as deserts. While generating electricity through the photovoltaic panel 1, it can also achieve the treatment of the surrounding environment, making the solar power generation and ecological treatment complement each other's shortcomings, and realizing multiple ecological benefits such as land improvement, sand fixation and land reclamation, wind sand control, and vegetation restoration while generating electricity. It can also provide high-quality forage, promote the development of animal husbandry, and improve economic and ecological benefits.
