[0029] The following will combine with the attached Figures 1 to 4 The embodiments of the technical solution of the present application will be described in detail. The following embodiments are only used to more clearly illustrate the technical solution of the present application, so they are only used as examples and cannot be used to limit the protection scope of the present application.

[0030] As Figure 1 Figure 11 schematically shows an embodiment of the lake water filtering device dedicated for microspray provided by the present application. The lake water filtering device dedicated for microspray includes: an outer filter screen 11, a middle filter screen 12, and an inner filter screen 13 that are sleeved in sequence from outside to inside. The filter hole diameters of the outer filter screen 11, the middle filter screen 12, and the inner filter screen 13 decrease in sequence; the outer filter screen 11, the middle filter screen 12, and the inner filter screen 13 are sleeved to form a columnar structure with an inner cavity 14; the inner cavity 14 enclosed by the inner filter screen 13 is used to place a water pump.

[0031] The lake water filtering device dedicated for microspray provided by this embodiment adopts an outer filter screen 11, a middle filter screen 12, and an inner filter screen 13 that are sleeved in sequence from outside to inside. The design of the three-layer filter screen can effectively intercept impurities of different sizes. Specifically, the filter hole diameters of the outer filter screen 11, the middle filter screen 12, and the inner filter screen 13 decrease in sequence. This design ensures that impurities of different sizes can be effectively intercepted at their respective filtration levels, avoiding small-sized impurities from penetrating through the large-aperture outer layer filter screen and directly entering the inner layer, thereby improving the overall filtration effect. The inner cavity 14 enclosed by the inner filter screen 13 is used to place a water pump, which can place the water pump in the filtered clean water area, effectively avoiding impurities from directly entering the inside of the water pump, extending the service life of the water pump, and at the same time reducing the impact of water pump failures on the sprinkler irrigation system.

[0032] Exemplarily, the filter hole diameter of the outer filter screen 11 can be set to 1.5 mm, the filter hole diameter of the middle filter screen 12 can be set to 40 mesh, and the filter hole diameter of the inner filter screen 13 can be set to 100 mesh. Through this filtration system, impurities in the lake water can be effectively filtered outside the lake water filtering device dedicated for microspray.

[0033] The lake water filtering device dedicated for microspray provided by this embodiment effectively solves the problems of damage and blockage of the nozzle by impurities in the traditional water intake and irrigation methods through a multi-layer filtration structure and an inner cavity design, improves the irrigation efficiency, extends the service life of the equipment, and has significant technical advantages and application prospects.

[0034] Continue to refer to Figure 1, in an improved embodiment of the special lake water filtration device for micro-spraying provided in the above embodiment, the space between the outer filter screen 11 and the middle filter screen 12 is filled with cobblestones. As a natural physical filtration medium, the cobblestones can further intercept larger impurities that the outer filter screen 11 fails to completely retain. The gaps between the cobblestones allow water to pass through, and will block and deposit the particulate matters suspended in the water, thereby improving the overall filtration efficiency.

[0035] Continue to refer to Figure 2 , in another preferred improved embodiment, the space between the middle filter screen 12 and the inner filter screen 13 is filled with filter cotton.

[0036] Due to its fine fiber structure, the filter cotton can intercept and adsorb finer impurities and suspended matters. These impurities may not be completely removed due to the larger pore diameters of the outer filter screen 11 and the middle filter screen 12, but the high-density fibers of the filter cotton can effectively capture these fine particles, thereby improving the overall filtration accuracy and effect.

[0037] It should be noted that the columnar structure in the above embodiment can adopt a square columnar or barrel-shaped structure. Preferably, a barrel-shaped structure can be adopted, and those skilled in the art can also adopt other structures under the inspiration of the embodiments of the present application. Due to its circular cross-sectional shape, the barrel-shaped structure has natural stability. When bearing the water flow pressure and external impacts, the barrel-shaped structure can better disperse the force and reduce the risk of deformation and damage.

[0038] Continue to refer to Figure 2 、 Figure 4 , the outer filter screen 11, the middle filter screen 12, and the inner filter screen 13 are detachably installed on the frame 2. It should be noted that the detachable structure can use common detachable structure types, such as bolt and nut connection, pin connection, key connection, flange connection, threaded connection, socket connection, etc. Those skilled in the art can select a specific structure type to realize the detachable installation of the outer filter screen 11, the middle filter screen 12, and the inner filter screen 13. The purpose of designing the outer filter screen 11, the middle filter screen 12, and the inner filter screen 13 to be detachably installed on the frame 2 is to facilitate the separate cleaning and maintenance of the filter screens. After adopting the detachable filter screens, when the filter screens are blocked or contaminated by impurities, they can be easily removed from the frame for cleaning or replacement, which not only simplifies the maintenance process but also improves the maintenance efficiency.

[0039] Refer to Figure 2 、 Figure 4In a preferred embodiment shown schematically, the frame body 2 includes an outer filter screen frame 21, a middle filter screen frame 22, and an inner filter screen frame 23 which are sleeved from outside to inside in sequence. The outer filter screen 11 is installed on the outer filter screen frame 21, the middle filter screen 12 is installed on the middle filter screen frame 22, and the inner filter screen 13 is installed on the inner filter screen frame 23. In this embodiment, through the outer filter screen frame 21, the middle filter screen frame 22, and the inner filter screen frame 23 sleeved from outside to inside in sequence, the independent installation and support of different filter screens are realized, which not only improves the structural stability of the filtering device, but also facilitates the cleaning and replacement of the filter screens.

[0040] Referring to Figure 2 、 Figure 4 , any one of the frame bodies 2 includes a bottom plate 201, a mounting portion 202 provided at the outer circumference of the bottom plate, and a limiting portion 203 located at the top of the frame body 2.

[0041] In this embodiment, whether it is the outer filter screen frame 21, the middle filter screen frame 22 or the inner filter screen frame 23, they all adopt a similar structural design. The bottom plate 201 of the frame body 2 is located at the bottom of the filter screen frame, playing a role in supporting the entire filter screen frame and the filter screen. The mounting portion 202 is provided at the outer edge of the bottom plate 201 for fixing the filter screen frame to the main body structure of the filtering device. The mounting portion 202 can be set as a bolt hole, a buckle or other connecting devices for tight connection with the filter screen. The limiting portion 203 is located at the top of the frame body 2, and its function is to limit the installation position of the filter screen and prevent the filter screen from shifting during the filtering process. The limiting portion 203 can be set as an annular structure or a series of positioning points. The limiting portion 203 matches the edge of the filter screen to ensure that the filter screen can be stably installed on the filter screen frame. Through the bottom plate 201, the mounting portion 202 and the limiting portion 203, each filter screen frame in the lake water filtering device dedicated to micro-spraying has the advantages of being stable, easy to install, and convenient to maintain.

[0042] Continuing to refer to Figure 2 、 Figure 4 , between the mounting portion 202 and the limiting portion 203, several reinforcing members 204 for reinforcing the frame body 2 are further provided. The reinforcing members 204 can effectively improve the overall structural strength of the frame body 2 by adding additional support and connection points. The reinforcing members 204 connect the mounting portion 202, the limiting portion 203 and the filter screen on the bottom plate 201 more firmly together, forming a more stable overall structure and improving the stability of the filtering device during operation. As Figure 4The illustrative reinforcement member 204 is a support rod structure, which plays a role in support and fixation. In the specific implementation process, those skilled in the art can determine the number, position, and length of the support rods according to the specific requirements of the filtration device. Those skilled in the art can also set the reinforcement member 204 as a connecting plate, which can be set as a horizontal or inclined plate-like structure, and can connect multiple points of components such as the bottom plate 201, the limiting part, and the filter net to form a more stable frame structure. The number and arrangement method of the connecting plates should also be determined according to the specific situation. Those skilled in the art can also set the reinforcement member as other types of structures, which will not be elaborated here.

[0043] Referring to Figure 3 , in a preferred embodiment, the lake water filtration device dedicated for microspraying further includes an upper cover 3 having a pipe outlet 31, and the upper cover 3 is arranged above the columnar structure. Especially when the filtration device is used in a deep water area, the upper cover 3 enables the filtration device to maintain its sealing property, preventing external impurities and pollutants from entering the interior of the filtration device from the top of the device, thereby ensuring the filtration effect.

[0044] Referring to Figures 1 to 4 , the lake water filtration device dedicated for microspraying further includes a support member 4 for supporting the frame 2.

[0045] The above-mentioned lake water filtration device dedicated for microspraying can be made of stainless steel, is a three-layer barrel structure, and each layer can be separated and cleaned. Among them, cobblestones are filled between the outer filter net and the middle filter net to block larger particle impurities; filter cotton is filled between the middle filter net and the inner filter net to block fine impurities. After 5-layer filtration, the water entering the water tank basically has no impurities that can block the water pump.
