[0049] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
[0050] like Figures 1-4 As shown, this utility model provides a photovoltaic drip irrigation system for desertification control, comprising:
[0051] Water storage tank 1, the inlet of water storage tank 1 is connected to the water supply source;
[0052] Water supply pump 11, the inlet end of which is connected to the outlet end of water storage tank 1;
[0053] Multiple drippers 5 are installed on the outside of the plant 3, and the multiple drippers 5 are connected to the outlet of the water supply pump 11 through a water supply pipe assembly.
[0054] Multiple photovoltaic panels 2 are installed on the windward side of the plant 3;
[0055] Multiple rainwater collection components 7 collect rainwater poured from the surfaces of multiple photovoltaic panels 2. The multiple rainwater collection components 7 are connected to the water storage tank 1 through a return water pipe assembly.
[0056] In this embodiment, water in the reservoir 1 is transported to the dripper 5 through the water supply pump 11 and the water supply pipe assembly. The plant 3 is then irrigated by drip irrigation through the dripper 5. This method of drip irrigation meets the water needs of the plant 3 and avoids water loss and waste.
[0057] When it rains, the rainwater collection component 7 can collect the rainwater pouring onto the surface of the photovoltaic panel 2, and transport the collected rainwater to the storage tank 1 for storage through the return water pipe group, so as to realize the recycling and reuse of rainwater and save water resources.
[0058] Multiple photovoltaic panels 2 are installed on the windward side of the plant 3, which can prevent wind and sand from blowing directly onto the plant 3, reduce the impact of wind and sand on the plant 3, and ensure the safety of the plant 3;
[0059] In this embodiment, in specific applications, the water supply pump 11 can be electrically connected to the controller. The controller has a timing function, which enables the water supply pump 11 to be turned on and off at set times, thereby controlling the start time and duration of the water supply pump 11 and ensuring that the water supply meets the water needs of the plant 3.
[0060] The upper end of the water storage tank 1 is detachably connected to a cover, which can prevent debris from entering the water storage tank 1 and facilitate regular cleaning of the water storage tank 1. The water inlet of the water storage tank 1 is connected to the water source through a water supply pipe, and a solenoid valve is installed on the water supply pipe. A liquid level sensor is installed inside the water storage tank 1 to detect the liquid level position of the water storage tank 1. Both the solenoid valve and the liquid level sensor are electrically connected to the controller. The liquid level sensor detects the liquid level position inside the water storage tank 1 and transmits the detection signal to the controller. When the liquid level position inside the water storage tank 1 is lower than the preset liquid level position, the controller controls the solenoid valve to open and replenish the water storage tank 1 with water, so as to realize the automatic water replenishment of the water storage tank 1.
[0061] In practical applications, a fertilizer tank can be installed outside the water storage tank 1. Fertilizer can be added into the water storage tank 1 through the fertilizer tank, so that the plants 3 can be fertilized while drip irrigation is supplying water, thus promoting the growth of the plants 3.
[0062] like Figure 1 As shown, in an optional embodiment of this utility model, the water supply pipe assembly includes:
[0063] A water supply main pipe 41 is connected to the outlet end of the water supply pump 11;
[0064] The first water supply branch pipe 42 is connected to the main water supply pipe 41;
[0065] Multiple first water supply branch pipes 43 connected to the first water supply branch pipe 42;
[0066] Multiple second water supply branch pipes 44 are connected to multiple first water supply branch pipes 43;
[0067] Multiple second water supply branch pipes 45 are connected to multiple second water supply pipes 44, and the multiple second water supply branch pipes 45 are connected to multiple drippers 5.
[0068] In this embodiment, when water is supplied, the water in the reservoir 1 is supplied to the dripper 5 through the water supply main pipe 41, the first water supply branch pipe 42, multiple first water supply branch pipes 43, multiple second water supply branch pipes 44 and multiple second water supply branch pipes 45 under the action of the water supply pump 11. Finally, the plant 3 is quantitatively drip-irrigated through the dripper 5, which meets the water needs of the plant 3 while avoiding water loss and waste, thus saving water resources.
[0069] like Figure 1 and Figure 2 As shown, in an optional embodiment of this utility model, the photovoltaic desertification control drip irrigation system further includes:
[0070] A first filter 46 is installed on the main water supply pipe 41;
[0071] A second filter 47 is connected between the second water supply branch pipe 45 and the dripper 5.
[0072] In this embodiment, the water discharged from the water storage tank 1 is filtered once by the first filter 46, and the water supplied to the dripper 5 is filtered twice by the second filter 47 to prevent impurities in the water from clogging the dripper 5 and to ensure that the dripper 5 works normally.
[0073] In this embodiment, the first filter 46 can be a disc filter or other existing filters capable of water filtration.
[0074] like Figure 3 As shown, in an optional embodiment of the present invention, the second filter 47 includes:
[0075] Water pipe 471, the first end of which is connected to the second water supply branch pipe 45, and the second end of which is connected to the dripper 5;
[0076] Inspection pipe 474 is connected to the bottom surface of water pipe 471;
[0077] A pre-filter 473 is installed at the connection between the inspection pipe 474 and the water guide pipe 471; a baffle 472 is connected to the inner top surface of the water guide pipe 471, the baffle 472 extends to the pre-filter 473, and a water passage space is formed between the baffle 472 and the pre-filter 473.
[0078] Sealing cap 475 is detachably connected to the port of inspection tube 474.
[0079] In this embodiment, when the second filter 47 filters the water, the water in the second water supply branch pipe 45 enters the water guide pipe 471 and is guided by the baffle 472 so that the water comes into contact with the pre-filter screen 473. Since the small impurities in the water are located at the bottom of the water, the impurities in the water will come into contact with the surface of the pre-filter screen 473. The pre-filter screen 473 blocks the impurities and prevents them from passing through. Thus, the pre-filter screen 473 can filter the small impurities in the water. The filtered water enters the dripper 5, which can prevent the dripper 5 from clogging and ensure that the dripper 5 works normally.
[0080] When drip irrigation is not in use, remove the sealing cover 475 and remove the pre-filter 473 through the inspection pipe 474. This makes it easier to clean the pre-filter 473, prevents it from becoming clogged, and ensures its filtration effect.
[0081] In this embodiment, the connection between the inspection pipe 474 and the water guide pipe 471 is funnel-shaped, and the inner wall of the funnel-shaped structure is formed with a groove structure for fixing the pre-filter 473, which facilitates the disassembly and installation of the pre-filter 473.
[0082] like Figure 1 As shown, in an optional embodiment of this utility model, the return water pipe assembly includes:
[0083] The return water main pipe 61 is connected to the water storage tank 1;
[0084] A return water collection pipe 62 is connected to the return water main pipe 61;
[0085] Multiple return water branch pipes 63 are connected to the return water collection pipe 62, and multiple rainwater collection components 7 are connected to the multiple return water branch pipes 63.
[0086] In this embodiment, rainwater collected by multiple rainwater collection components 7 flows into the water storage tank 1 through multiple return water branch pipes 63, return water collection pipes 62 and return water main pipes 61, realizing rainwater recycling, facilitating the reuse of rainwater, and helping to save water resources.
[0087] like Figure 2 and Figure 4 As shown, in an optional embodiment of the present invention, the plurality of rainwater harvesting components 7 include:
[0088] The upper opening of the half-pipe 71 is inclined and faces the inclined bottom end of the photovoltaic panel 2. The half-pipe 71 is connected to the return water branch pipe 63.
[0089] The first filter screen 72 is connected to the upper opening of the half-tube 71.
[0090] In this embodiment, when it rains, rainwater pours down along the photovoltaic panel 2 and is collected on the surface of the photovoltaic panel 2 through the semi-pipe 71; the first filter screen 72 filters out impurities mixed in with the rainwater, ensuring that the rainwater can flow into the water storage tank 1 through the semi-pipe 71, multiple return water branch pipes 63, return water collection pipe 62 and return water main pipe 61, thereby realizing the recycling of rainwater.
[0091] The upper opening of the semi-tube 71 is inclined, which can ensure that rainwater poured from the surface of the photovoltaic panel 2 can accurately enter the semi-tube 71; at the same time, it can make the first filter screen 72 in an inclined state, so that the debris filtered by the first filter screen 72 can slide down and get off the first filter screen 72 under the action of gravity, thus avoiding clogging of the first filter screen 72.
[0092] In this embodiment, when applied in practice, a guide pipe is connected to the middle of the half-pipe 71. The half-pipe 71 is connected to the return water branch pipe 63 through the guide pipe. Both ends of the half-pipe 71 are inclined upwards, so that the connection between the guide pipe and the half-pipe 71 is located at the bottom of the inclination. This allows the rainwater collected by the half-pipe 71 to completely enter the return water branch pipe 63 through the guide pipe, ensuring the rainwater collection effect.
[0093] like Figure 4 As shown, in an optional embodiment of the present invention, the plurality of rainwater harvesting components 7 further include:
[0094] Two fasteners 73 are connected to both sides of the first filter screen 72. The two fasteners 73 are detachably fastened to both ends of the upper opening of the half tube 71.
[0095] In this embodiment, the fastener 73 is an inverted U-shaped structure, which makes it easy for the fastener 73 to be snapped onto both ends of the upper opening of the half tube 71, thereby realizing the detachable connection between the first filter screen 72 and the half tube 71. This makes it easy to remove the first filter screen 72, thereby making it easy to clean the first filter screen 72, avoiding clogging of the first filter screen 72, and ensuring the filtration effect of the first filter screen 72.
[0096] In this embodiment, the first filter screen 72 can be a multi-layer structure, and the diameter of the mesh holes of the first filter screen 72 decreases from top to bottom, which can improve the filtration effect of the first filter screen 72 on impurities of different sizes in rainwater.
[0097] like Figure 2 As shown, in an optional embodiment of the present invention, the half-pipe 71, the water supply pipe assembly, and the return water pipe assembly are all suspended and fixed by the bracket 8.
[0098] In this embodiment, the bracket 8 is used to suspend and fix the half-pipe 71, which ensures the stability of the half-pipe 71 and reduces the chance of wind and sand entering the half-pipe 71.
[0099] The water supply and return pipe assemblies are suspended and fixed by bracket 8, which can prevent sand from covering them and expose them, making it easier to detect any leaks and to carry out inspection and maintenance.
[0100] like Figure 1 As shown, in an optional embodiment of this utility model, the photovoltaic desertification control drip irrigation system further includes:
[0101] The return water tank 14 is connected to the water storage tank 1, and the return water main pipe 61 is connected to the return water tank 14;
[0102] A second filter screen 12 is installed in the return water tank 14, and the second filter screen 12 is close to the return water main pipe 61;
[0103] The filter cotton 13 is installed in the return water tank 14 and is close to the water storage tank 1.
[0104] In this embodiment, by setting a second filter screen 12 and filter cotton 13 in the return water tank 14, the rainwater flowing into the return water tank 14 from the return water main pipe 61 can be filtered to prevent impurities in the rainwater from entering the water storage tank 1.
[0105] In this embodiment, the inner wall of the return water tank 14 is provided with an insertion slot for inserting the second filter screen 12 and the filter cotton 13, which facilitates the disassembly and assembly of the second filter screen 12 and the filter cotton 13, thereby facilitating the cleaning or replacement of the second filter screen 12 and the filter cotton 13 and ensuring the filtration effect of the second filter screen 12 and the filter cotton 13.
[0106] like Figure 1 As shown, in an optional embodiment of the present invention, each plant 3 is provided with multiple drippers 5, and the multiple drippers 5 are symmetrically arranged on both sides of the plant 3.
[0107] In this embodiment, by symmetrically setting multiple drippers 5 on both sides of the plant 3, it can be ensured that the roots of the plant 3 fully absorb water, thus ensuring the drip irrigation effect on the plant 3.
[0108] In this embodiment, the water outlet of the dripper 5 is tilted upward and away from the ground, which can prevent the wind from blowing sand from the ground to the water outlet of the dripper 5 and causing the dripper 5 to become clogged, thus helping to ensure that the dripper 5 works normally.
[0109] The above-described embodiments of this utility model provide water for the plants 3 via drip irrigation through the water storage tank 1, water supply pump 11, water supply pipe assembly, and drippers 5, meeting the water needs of the plants 3 while avoiding water loss and waste; the rainwater collection assembly 7 and return pipe assembly collect and store the rainwater poured from the photovoltaic panels 2 in the water storage tank 1, realizing rainwater recycling and reuse, saving water resources; the first filter 46 and the second filter 47 perform dual filtration of the water to prevent impurities in the water from clogging the drippers 5; the bracket 8 suspends and fixes the semi-pipe 71, ensuring the stability of the semi-pipe 71 and reducing the amount of wind and sand entering the interior of the semi-pipe 71. The water supply and return pipe groups are suspended and fixed by the bracket 8, which can prevent sand from covering the water supply and return pipe groups, leaving them exposed, making it easier to detect any leaks in the water supply and return pipe groups in a timely manner, and facilitating the inspection and maintenance of the water supply and return pipe groups; by installing a second filter screen 12 and filter cotton 13 in the return water tank 14, the rainwater flowing into the return water tank 14 from the return water main 61 can be filtered, preventing impurities in the rainwater from entering the water storage tank 1; the water outlet of the dripper 5 is tilted upward and away from the ground, which can prevent the wind from blowing sand from the ground to the water outlet of the dripper 5 and causing the dripper 5 to be blocked, thus helping to ensure the normal operation of the dripper 5.
[0110] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
