Description

Technical Field

[0001] This utility model relates to a water collection and irrigation device, specifically a photovoltaic panel water collection and irrigation device. Background Technology

[0002] Large-scale photovoltaic power plants occupy grasslands, deserts, and other lands. Due to the shading effect of the photovoltaic panels, they impact the structure and function of the ecosystem, especially causing vegetation beneath the panels to suffer from water shortages and stunted growth. Therefore, water redistribution is crucial to the ecosystem.

[0003] In response to the problem of insufficient rainfall from photovoltaic panels, some water collection and irrigation devices have been disclosed, as follows:

[0004] (1) Chinese Patent CN202020460000.0 discloses a photovoltaic water pumping irrigation system, including a photovoltaic module, multiple soil moisture sensors, a fertilization device, an irrigation device, and a controller. The signal output terminals of the multiple soil moisture sensors are electrically connected to the signal input terminal of the controller, and the multiple soil moisture sensors are evenly distributed in the farmland. The signal output terminal of the controller is electrically connected to the signal input terminals of the fertilization device and the irrigation device. The irrigation device is connected to the fertilization device through a delivery pipe. The fertilization device is connected to the farmland through a delivery pipe, and the output terminal of the delivery pipe is connected to the sprinkler nozzles evenly distributed in the farmland. The power output terminal of the photovoltaic module is electrically connected to the multiple soil moisture sensors, the fertilization device, the irrigation device, and the controller. This patent uses photovoltaic water pumping technology to provide power for water pumping using solar energy, converting solar energy into electrical energy to provide a continuous power source for the irrigation system.

[0005] (2) Chinese Patent CN201820467118.9 discloses a large-scale photovoltaic rainwater harvesting irrigation system, which includes: photovoltaic power generation components, photovoltaic brackets, combiner boxes, inverters, transformers, rainwater harvesting troughs, sedimentation tanks, confluence ditches, water cellars, water delivery pipes, drip irrigation tapes and drainage ditches. The photovoltaic (PV) power generation modules are installed on the upper part of the PV support structure. No crops are planted between the PV modules; only walkways are provided. Rainwater is collected by the PV modules and channeled through a drainage system before flowing into a water cellar as irrigation water. During the irrigation season, a drip irrigation system supplies water to the roots of crops or fruit trees. A sedimentation tank is built at the connection between the rainwater collection trough and the drainage ditch. The rainwater collection trough and the water cellar are connected via the drainage ditch, and the water cellar is connected to the drip irrigation system via a water pipe. The water cellar is located in the middle of the drainage ditch, and a drainage ditch is also provided perpendicular to the rainwater collection trough. The PV power generation system consists of PV modules, PV support structures, combiner boxes, inverters, and transformers. The PV modules and inverters are connected through the combiner boxes. The direct current (DC) generated by the PV modules is converted to alternating current (AC) by the inverter, and the AC power is then fed into the national power grid through the transformer. During rainfall, the PV modules collect rainwater, which flows into the drainage ditch through the rainwater collection trough.

[0006] Chinese patent CN202020460000.0 requires the use of photovoltaic panels to power the irrigation water source, and cannot utilize rainwater. Although Chinese patent CN201820467118.9 utilizes rainwater, it requires all rainwater to be collected before irrigation, and still needs additional power.

[0007] Therefore, there is a need to design a device that uses rainwater to irrigate the land occupied by photovoltaic panels without external power source, which can be used directly on existing photovoltaic power stations without any modifications and protects the vegetation.

[0008] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0027] This utility model relates to a photovoltaic panel water collection and irrigation device, see [link to relevant documentation]. Figures 1-2 The device includes: an upper photovoltaic panel 10, a lower photovoltaic panel 20, a support frame, a water collection tank 30, partition plates 40, diversion channels 50, and a drainage channel 60. Both the upper photovoltaic panel 10 and the lower photovoltaic panel 20 are inclinedly mounted on top of the support frame, with a gap between them. A water collection tank 30 is provided along the edge of the upper end of the lower photovoltaic panel 20, and is detachably fixed to the upper end of the lower photovoltaic panel 20. Several partition plates 40 are arranged axially within the water collection tank 30 to divide it into several water collection chambers. Each water collection chamber has an outlet at its bottom. A diversion channel 50 is fixed to the outlet of the water collection chamber at an angle to the ground, and has several outlets 2 on it. The diversion channels 50 connected to adjacent water collection chambers alternately divert water to both sides of the water collection tank 30. Several diversion channels 60 are fixedly installed on the upper photovoltaic panel 10, and each water collection chamber is connected to one diversion channel 60.

[0028] For example, the water collection tank 30 may be a pipe with a radial cross section of U or semi-circle, and the length is set to 100cm.

[0029] According to a specific embodiment of this utility model, two water outlets are provided at equal intervals on the diversion channel 50.

[0030] For example, the second water outlet can be configured as a rectangular hole with a hole spacing of 10cm.

[0031] According to a specific embodiment of this utility model, the size of the second water outlet is determined based on its distance from the first water outlet; the farther away from the first water outlet, the larger the size of the second water outlet.

[0032] According to a specific embodiment of the present invention, the angle between the diversion channel 50 and the ground is 30 degrees.

[0033] According to a specific embodiment of the present invention, the length of the diversion channel 50 is determined based on the length of the lower photovoltaic panel 20.

[0034] For example, the length of the diversion channel 50 is set to 40cm.

[0035] According to a specific embodiment of the present invention, a second baffle is vertically provided on the upper edge of the lower photovoltaic panel 20, and the water collection tank 30 is hung on the second baffle by a hook.

[0036] According to a specific embodiment of the present invention, a first baffle is vertically arranged on the upper edge of the upper photovoltaic panel 10, and the diversion channel 60 is composed of three parts connected in sequence: a water collection part, a diversion part, and a connecting part.

[0039] When rainwater flows down from the upper photovoltaic panel 10, it is diverted to the water collection tank 30 through the diversion channel 60, and then evenly sprinkled on the area below the photovoltaic panel that needs irrigation through the diversion channel 50, so as to achieve effective irrigation of the plants below the photovoltaic panel.

[0040] Furthermore, the direction of rainwater flow can be changed by utilizing the extension direction and opening position of the diversion channels 50. They are arranged horizontally in a crisscross pattern to control the direction of water flow. For example, if the diversion channel 50 on the first collection chamber diverts water to the left side of the collection chamber, the diversion channel 50 on the second collection chamber diverts water to the right side of the collection chamber, the diversion channel 50 on the third collection chamber diverts water to the left side of the collection chamber, and the diversion channel 50 on the fourth collection chamber diverts water to the right side of the collection chamber, and so on, diverting water to the left and right in turn.
