Description

Technical Field

[0001] This application relates to the technical field of drip irrigation devices, and particularly to a photovoltaic drip irrigation device with automatic rainwater collection and water replenishment. Background Art

[0002] Drip irrigation is the most effective water-saving irrigation method in arid and water-scarce areas. In order to save water, drip irrigation is currently also used in many greening maintenance. In order to be more energy-saving and environmentally friendly, many drip irrigation devices for greening maintenance are equipped with rainwater collection devices.

[0003] The existing Chinese patent with the publication number CN218921203U discloses a water-saving irrigation system. After rainwater enters the water collection tank, it is filtered through the first filter screen. The sediment after filtration accumulates on the first filter screen. Since the first filter screen is arranged in the water collection tank, it is not convenient to deal with the sediment on the first filter screen, and there is room for improvement. Utility Model Content

[0004] The purpose of this application is to provide a photovoltaic drip irrigation device with automatic rainwater collection and water replenishment, in order to facilitate the treatment of sediment.

[0005] A photovoltaic drip irrigation device with automatic rainwater collection and water replenishment provided by this application adopts the following technical solutions: It includes a water storage tank, the water storage tank is connected with a water inlet pipe and a water outlet pipe, the water outlet pipe is connected with a drip irrigation assembly, one end of the water inlet pipe far away from the water storage tank is connected with a water collection tank, the water collection tank is provided with a water collection cavity, the water collection tank is connected with a filter plate for covering the water collection cavity, a filter frame is arranged in the water inlet pipe, the filter frame is provided with a first filter screen, the filter frame is connected with a connecting plate, the connecting rod is connected with a connecting rod, the connecting rod is connected with a cover plate, the filter plate is provided with a passage for the filter frame to pass through, the cover plate is used for covering the opening of the passage, and the cover plate and the filter frame are connected by a fixing piece.

[0006] By adopting the above technical solutions, by arranging a filter plate on the water collection tank, it can effectively prevent leaves from entering the water collection tank and play a role in preliminary filtration. A filter frame with a first filter screen is arranged in the water inlet pipe, which can effectively prevent dust from entering the water storage tank and reduce the trouble of subsequent cleaning work. When it is necessary to deal with the impurities in the filter frame, the fixing piece loosens the connection between the cover plate and the filter frame, moves the cover plate, and the filter frame moves along with the movement of the cover plate, so that the filter frame passes through the passage and moves to the outside, thus facilitating the treatment of the sediment in the filter frame.

[0007] Optionally, a convex column is arranged on one side of the filter frame close to the connecting plate, and the first filter screen is arranged on the convex column.

[0008] By adopting the above technical solution, the convex columns are provided, which increases the contact area between the first filter screen and rainwater and improves the filtration efficiency of rainwater.

[0009] Optionally, the filter plate is provided with an installation groove for the cover plate to be snapped into, and the installation groove communicates with the channel. When the cover plate is snapped into the installation groove, the outer peripheral surface of the filter frame fits against the inner wall of the water inlet pipe.

[0010] By adopting the above technical solution, the outer peripheral surface of the filter frame fits against the inner wall of the water inlet pipe, which can effectively prevent impurities in rainwater from entering the water storage tank through the gap between the filter frame and the water inlet pipe, thereby improving the filtration effect. At the same time, the design of snapping the cover plate into the installation groove is convenient for installation, facilitating the user to clean the filter frame and improving the maintenance convenience of the device.

The settings of the bolts, through holes and threaded holes achieve reliable fixation between the cover plate and the filter plate, ensuring the stable installation of the filter frame in the water inlet pipe and preventing loosening caused by water flow impact. At the same time, the design of the through holes being automatically aligned with the threaded holes when the positioning blocks are snapped into the positioning grooves simplifies the assembly process and improves the assembly efficiency.

[0013] Optionally, the connecting plate is provided with installation holes for the connecting rods to pass through.

The threaded connection method is convenient for disassembly and assembly, allowing the user to quickly disassemble the filter frame when needed, facilitating the handling of sediments in the filter frame.

[0015] Optionally, a handle is provided on the side of the cover plate away from the connecting rod.

[0016] By adopting the above technical solution, the provision of the handle enables the user to more conveniently lift the cover plate, thereby facilitating the cleaning of the filter frame.

A second filter screen is connected inside the water inlet pipe, and the feed inlet of the discharge pipe is located between the second filter screen and the filter frame.

[0018] By adopting the above technical solution, rainwater can be double-filtered by the first filter screen and the second filter screen before entering the water storage tank, effectively intercepting impurities such as leaves and dust. The setting of the second filter screen further improves the filtering effect, ensuring that impurities do not enter the water storage tank, thus avoiding the trouble of cleaning caused by the accumulation of impurities. The combined design of the discharge pipe and the aggregate box enables the impurities intercepted by the second filter screen to be conveniently collected and cleaned, improving the maintenance convenience of the device.

[0019] Optionally, the second filter screen is inclined, and the second filter screen corresponds to the feed inlet of the discharge pipe.

[0020] By adopting the above technical solution, the inclined filter screen can effectively guide the impurities to slide towards the feed inlet of the discharge pipe, facilitating the centralized collection of the filtered impurities.

[0021] Optionally, the drip irrigation assembly includes a water pump connected to the water outlet pipe, a main pipe connected to the water outlet pipe, a plurality of shunt pipes connected to the main pipe, and a plurality of drip irrigation parts connected to the shunt pipes.

[0022] By adopting the above technical solution, the water pump pumps the water in the water storage tank into the main pipe, enabling the water to flow to each shunt pipe and discharge from the drip irrigation parts, ensuring that the water is delivered to each area.

[0023] Optionally, the water storage tank is connected with a storage battery and a plurality of photovoltaic panels, and both the photovoltaic panels and the water pump are electrically connected to the storage battery.
