DETAILED DESCRIPTION

[0022] The technical solutions in the utility model will be clearly and completely described below in combination with the drawings in the utility model.

[0023] Embodiment one: the water-saving irrigation device of the utility model is mainly composed of an irrigation box 100, and the specific structure and connection mode of the core components are as follows:

[0024] Irrigation box structure:

[0025] The irrigation box 100 comprises a box body 110 and a cover plate 111, the box body 110 is in the form of a container with an open top, and the opening is matched with the cover plate 111 through a detachable mounting mode, for example, a connection mode of a clamping groove and a clamping block or a bolt connection mode, and the detachable design facilitates the cleaning, maintenance of the inside of the box body and the overhaul and replacement of components.

[0026] A water filling pipe 112 is welded or connected through threads on one side of the box body 110, the water filling pipe 112 is used for supplementing irrigation water into the box body 110, the water inlet end can be connected with an external water source such as a faucet or a water storage container, and a valve can be arranged on the water filling pipe 112 according to actual needs to control the water inlet flow and the opening and closing state.

[0027] The other side of the box body 110 is also fixedly connected with an irrigation main pipe 113 through welding or flange connection, the irrigation main pipe 113 serves as a main water conveying channel and conveys water in the box body 110 to each irrigation branch pipe 114.

[0028] A plurality of irrigation branch pipes 114 are uniformly distributed along the length direction of the irrigation main pipe 113 at certain interval distances (for example, every 1-2 meters, and the specific interval can be adjusted according to the size of the actual irrigation area and the planting layout of crops), and these irrigation branch pipes 114 can be connected with the irrigation main pipe 113 through welding, hot melting connection or sealed threaded connection, so as to ensure the sealing property of the connection position and prevent water leakage, thereby ensuring the stable operation of the irrigation system and the effective utilization of water resources.

[0029] Filter mechanism setting:

[0030] A filtration mechanism is installed on the irrigation main pipe 113, which mainly consists of a filter cylinder 115. The filter cylinder 115 is securely installed on the irrigation main pipe 113 by means of threaded connection, flange connection or snap-fit ​​connection, and is located near the water outlet of the tank body 110, so as to filter the water flowing out of the tank body 110.

[0031] Inside the filter cylinder 115, along the water flow direction, are arranged a coarse filter 120, a fine filter 121, and an activated carbon filter 122 in sequence. The coarse filter 120 has a larger mesh size and is mainly used to intercept larger particles of impurities in the water, such as silt and stones. The fine filter 121 has a relatively smaller mesh size and can further filter out smaller suspended solids and impurity particles in the water. The activated carbon filter 122 utilizes its porous structure and adsorption properties to remove organic matter, odors, and some microorganisms from the water, thereby providing comprehensive and effective purification of irrigation water, preventing impurities from entering the irrigation branch pipe 114 and subsequent sprinklers (if any), avoiding sprinkler blockage, and ensuring the uniformity and stability of irrigation.

[0032] To facilitate regular cleaning and replacement of the filters, the coarse filter 120, fine filter 121, and activated carbon filter 122 are all designed for detachable installation. For example, easily removable end caps can be provided at both ends of the filter cartridge 115. By rotating, inserting, or snapping the end caps, the filter screens can be removed for cleaning or replacement, ensuring that the filtration mechanism always maintains good filtration performance.

[0033] Example 2

[0034] Based on Example 1, Example 2 adds and improves the following aspects of structure and function:

[0035] Anti-drip mechanism:

[0036] Each irrigation branch pipe 114 is equipped with an anti-drip mechanism, which mainly consists of an anti-drip cylinder 116. The anti-drip cylinder 116 is fixed to the irrigation branch pipe 114 by means of sealing welding or high-strength sealant connection to ensure that no water leakage occurs at the connection.

[0037] Inside the anti-drip cylinder 116 is a base plate 125. The base plate 125 is made of corrosion-resistant materials such as metal or high-strength plastic. Multiple through holes are evenly opened on it. The size and distribution density of the through holes are reasonably designed according to the flow rate and irrigation needs of the irrigation branch pipe 114 to ensure that the water flow can pass through evenly.

[0038] A spring 124 is connected to one side of the substrate 125, and a sealing plug 123 is installed at the other end of the spring 124. The sealing plug 123 is made of soft and good sealing material such as rubber or silicone, and its shape and size match the internal space of the drip-proof cylinder 116, which can tightly fit on the substrate 125 under the elastic force of the spring 124, thereby effectively sealing the through hole and preventing water droplets from leaking due to residual water pressure or gravity in the branch pipe after irrigation stops, further improving the water-saving performance of the irrigation system.

[0039] When the irrigation system is working normally, the water flow pressure overcomes the elastic force of the spring 124, pushes the sealing plug 123 away from the substrate 125, so that the water can smoothly pass through the through hole into the irrigation branch pipe 114 for irrigation; and when the irrigation stops, the water flow pressure disappears, the spring 124 quickly pushes the sealing plug 123 back to its original position, realizing the sealing of the through hole and avoiding the dripping phenomenon.

[0040] Water level monitoring and automatic water replenishment system:

[0041] Observation windows 119 are installed on the front and back of the box body 110, which are made of high-strength, wear-resistant, anti-aging and high-transparency organic glass or tempered glass, and are tightly combined with the box body 110 by sealing glue to ensure its sealing and reliability, preventing water leakage and fog from entering and affecting the observation effect.

[0042] Clear scale lines are accurately engraved on the observation windows 119, which are made of fluorescent material. Even in a relatively dark environment, such as early morning, evening or night, the operator can clearly read the water level in the box body 110, which is convenient for timely understanding of the remaining amount of irrigation water, so as to reasonably arrange the irrigation plan and supplement the water source.

[0043] At the same time, a liquid level sensor 117 is installed inside the box body 110, which adopts high-precision pressure or ultrasonic liquid level detection technology, can real-time and accurately monitor the water level height in the box body 110, and convert the water level signal into an electrical signal to transmit to the external control unit (such as PLC controller, single-chip microcomputer or intelligent irrigation controller, etc.).

[0044] The water filling pipe 112 is equipped with an automatic water supplement valve 118, which can be an electromagnetic valve or an electric valve with automatic control function. When the water level sensor 117 detects that the water level in the tank body 110 is below the preset minimum water level, the control unit receives the signal and automatically issues an instruction to open the automatic water supplement valve 118. The external water source supplements the irrigation water into the tank body 110 through the water filling pipe 112. When the water level reaches the preset maximum water level, the control unit issues an instruction again to close the automatic water supplement valve 118 and stop the water supplement, thereby realizing the automatic water supplement function of the irrigation tank 100, ensuring the sufficient supply of irrigation water, and avoiding the irrigation problems caused by manual water supplementing not in time or excessive water supplementing, improving the automation degree and reliability of the irrigation system.

[0045] Pipe material and connection method:

[0046] The irrigation main pipe 113 and the irrigation branch pipe 114 are made of corrosion-resistant, high-pressure-resistant, and smooth-walled materials, such as PVC pipes, PE pipes, or stainless steel pipes. These materials have good chemical stability and mechanical strength, can withstand the water pressure generated during the operation of the irrigation system, and the smooth-walled characteristics can effectively reduce water flow resistance, improve water flow speed and irrigation efficiency, and reduce the possibility of impurities generated inside the pipe due to water flow erosion and friction, further prolonging the service life of the pipe.

[0047] The connection between the irrigation main pipe 113 and the irrigation branch pipe 114 uses a quick connection joint with good sealing performance, such as a plug-in quick joint, a sleeve joint, or a threaded joint connected by a sealing rubber ring. These connection methods not only are convenient and fast to install, greatly shortening the installation time and cost of the irrigation system, but also ensure the sealing performance of the connection while facilitating the disassembly and maintenance of the pipe when needed, improving the maintainability and flexibility of the system.

[0048] Protective layer and warning sign:

[0049] The irrigation tank 100 is wrapped with a protective layer on the outside. The protective layer is made of composite materials with heat insulation, sun protection, and rust prevention, such as spraying heat insulation and rust prevention paint on the surface of the metal tank body, or sticking heat insulation and sun protection film on the outside of the plastic tank body. This protective layer can effectively block the direct sunlight, high temperature radiation, and moisture, acid and alkali substances in the external environment from eroding and damaging the irrigation tank 100, prolonging the service life of the irrigation tank 100 and reducing the maintenance cost and replacement frequency of the equipment.

[0050] The surface of the protection layer is further provided with obvious warning signs made of wear-resistant and corrosion-resistant materials, such as plastic stickers or metal nameplates, and the warning signs are marked with safety precautions and operation specifications related to the irrigation system, such as "high pressure danger", "prohibit random movement", "pay attention to waterproof", and other prompt information, so as to remind the operator to pay attention to safety when using and maintaining the irrigation system, avoid personal injury and equipment damage accidents caused by misoperation, and ensure the safety and smooth operation of the irrigation work.

[0051] Through the detailed description of the above embodiment one and embodiment two, the specific structure, functional characteristics, connection relationship between components and working principle of the water-saving irrigation device of the utility model can be clearly understood, so that the person skilled in the art can accurately implement the utility model according to the actual demand and application scene, realize efficient, water-saving and stable irrigation work, and provide a reliable irrigation solution for the field of agricultural production, landscape irrigation and the like.

[0052] In the actual production and application process, the water-saving irrigation device of the utility model can be properly adjusted and optimized according to specific irrigation requirements, water source conditions, crop types and site environment and other factors, for example, adjusting the filter screen aperture and the number of layers of the filtering mechanism, changing the spring elastic coefficient and the size of the sealing plug of the anti-dripping mechanism, optimizing the detection accuracy of the liquid level sensor and the flow control parameter of the automatic water replenishment valve, and the like, so as to further improve the performance and adaptability of the irrigation device, meet the individualized needs of different users, and fully exert the advantages and value of the utility model.

[0053] The above implementation manners are only preferred embodiments of the utility model, and do not limit the protection scope of the utility model, and any improvement and deformation based on the technical scheme of the utility model should be covered in the protection scope of the utility model.
