[0030] It should also be noted that the drawings provided in the following embodiments only schematically illustrate the basic concept of the present disclosure, and only the components related to the present disclosure are shown in the drawings, not the number, shape and size of the components when actually implemented. The shape, number and ratio of each component in actual implementation can be arbitrarily changed, and the layout type of the components can also be more complex.

[0031] Also in the following description, specific details are provided to thoroughly understand examples. However, one of ordinary skill in the art will appreciate that the aspects described can be practiced without these specific details.

[0032] As shown in Figure 1 and Figure 2 , a water-saving irrigation water storage tank of the present application includes a main structure, i.e. the water tank body 1. The water tank body 1 serves as the core component of the entire water storage device, responsible for providing space to accommodate and store water resources to be irrigated. This part of the structure usually has a certain volume and size range to meet the cumulative storage of the required water volume for irrigation in different application scenarios. As an example, assuming that the water tank is designed in a cylindrical shape, its diameter can be set between 1 to 3 meters and the height can be selectively adjusted within the range of 2 to 4 meters according to the water storage capacity of the customer's requirements in actual productization.

[0033] The water inlet pipe 2 is a pipe structure connected to the external water source introduction system, located at the top end of the water storage tank. Its installation position is carefully considered to ensure smooth water flow into the interior while reducing the impact of turbulence on subsequent flow characteristics. In specific implementation cases, if the water supply equipment such as a water pump is set at a relatively low elevation, the delivery efficiency can be ensured by increasing the pipe length or using flexible pipe materials; in addition, in order to facilitate maintenance and repair, sufficient operational space is reserved outside the inlet and a flange connection form that is easy to disassemble is provided to facilitate cleaning of clogged materials or regular inspection of the internal situation.

[0034] The flow distribution plate 3 is placed in the lower half of the container mentioned above. The unique feature of this component is that it is constructed as a mesh baffle system composed of a series of longitudinal and transverse interlaced strip-shaped protrusions. These constituent elements collectively form a grid hole structure composed of a large number of openings of different sizes, and the aperture decreases from the inlet to the water outlet end to control the water volume in each area to achieve a balanced state.

[0035] The water outlet assembly 4 is dispersedly arranged at the periphery of the water storage tank bottom, including a collection of multiple independent and small-diameter small discharge components. Each single body has a separate sealing performance and direction guiding mechanism to allow water to be ejected outward at a specified angle to achieve a full-range uniform water distribution effect. For example, for a greenhouse vegetable cultivation system, evenly fix this device around the circular flower bed and keep it consistent in the horizontal direction, then each plant can be ensured to receive an appropriate amount of water nourishment without uneven wet and dry conditions.

[0036] The support ribs 5, as an important accessory for enhancing the overall strength and supporting the stability of the internal partition device, are installed in an orderly manner at a predetermined interval between the inner side of the entire box and the edge of the flow distribution plate 3, ensuring the firm fit of the latter without affecting the free flow properties of the normal liquid transmission path. The top part has a proper gap above the top plate to prevent interference with the operation of other facilities, and the bottom part also has a certain interval from the ground to avoid the problem of local congestion caused by the deposition of impurities; in order to strengthen the compression bending resistance performance of the middle section, reinforcement measures are taken through several vertical connection points, which creates more ideal operating conditions for the entire partition layout and improves the rationality and consistency of internal water distribution.

[0037] On the one hand, the application makes the water flow produce a sorting and screening function during the process of flowing through the grid layer by reasonably configuring the asymmetric shape of the channel structure, thereby achieving a more balanced state distribution at the macro scale level; on the other hand, the additional auxiliary frame structure is used to provide additional support to create a stable premise for the formation of complex flow patterns, thereby significantly improving the uniformity of water distribution coverage area and better meeting the needs of fine adjustment for specific planting requirements in agricultural practice. On this basis, higher resource utilization is achieved, ensuring that each irrigation task can be completed efficiently and saving valuable water resources as much as possible.

[0038] In one embodiment, the water inlet pipe 2 of the water storage tank for water-saving irrigation of the application is inclined downward (as shown in Figure 1 By this design feature, the mixing of external air into the water flow is effectively reduced, the path of the water flow into the water tank body 1 is optimized, and it is ensured that the water source can be smoothly and efficiently introduced into the water tank. In addition, the setting of the inclination angle also helps to prevent air bubbles in the water flow from stagnating or accumulating during the process of entering the water tank, improving the overall working stability and efficiency of the system.

[0039] For example, one end of the water inlet pipe 2 is connected to an external water source, and the other end is fixedly installed on the upper end of the water tank body 1 at a certain downward inclination angle. The inclination angle is selected according to the fluid mechanics requirements in specific application scenarios, and is usually set between 5 to 15 degrees, thereby ensuring smooth water flow while reducing the possibility of air intake. Under this design, the water inlet pipe 2 can ensure sufficient flow while making the water flow more uniform and rapid to the bottom of the water tank, further supporting the energy-saving and efficient operation of the system.

[0040] By precisely designing and rationally arranging the positions of the components, not only is it ensured that the external water source can be smoothly injected and fill the entire water storage space, but also unnecessary foam or gas inclusions caused by water flow impact are avoided, which helps to maintain a stable internal water environment. This unique inclined structure provides a reliable way for the irrigation system, making the storage and delivery of water resources more efficient.

[0041] In one embodiment, the flow distribution plate 3 of the water-saving irrigation water storage tank of the present application is composed of several interlaced strip-shaped protrusions, forming a multi-level asymmetrically distributed grid structure. The grid hole size decreases according to an arithmetic progression from the water inlet side to the water outlet side, ensuring uniform distribution of water flow in each area. Specifically, the size variation of the grid holes is achieved through precise design to regulate water flow at different positions, so that water can effectively and uniformly reach each part of the water storage tank. This asymmetric design helps to find a balance point between water flow and distribution, ensuring water balance during irrigation.

[0042] The flow distribution plate 3 in the above structure is located inside and below the water tank body 1, and multiple interlaced strip-shaped protrusions are arranged along the horizontal and vertical directions to form a complex grid network. This design not only increases the variation of water flow path, but also further adjusts the uniformity of water volume through the gradually shrinking hole diameter. The support ribs 5 are regularly arranged between the inner wall of the water tank body 1 and the edge of the flow distribution plate 3, which play a role in fixing and reinforcing the flow distribution plate 3. The top end of the support rib 5 is close to but does not touch the top wall of the water tank, and the bottom end is kept a certain distance from the bottom of the tank to prevent blockage. In addition, the support rib 5 maintains rigidity and perpendicularity through the intermediate spacing connector, ensuring the stability of the entire structure without affecting the water flow path.

[0043] For example, a metal plate with a certain thickness and flatness can be manufactured by a numerical control machine as the material of the flow distribution plate 3, and the required interlaced protrusion structure is cut at specific positions. Next, larger diameter round holes are machined on the water inlet side, and as gradually moving towards the water outlet side, the hole diameter gradually decreases according to an arithmetic progression, until reaching the designed minimum value. Finally, through precise assembly, the flow distribution plate 3 is fixed at the designated position in the water storage tank, and a special support rib 5 is used to stabilize it, completing the entire installation process.

[0044] In one embodiment, the outlet pipe of the water outlet assembly 4 of the water-saving irrigation water storage tank of the present application adopts a spiral design. The core of this design is to use the shape of the pipe to produce a slight vortex effect on the water flowing through it, promoting the water flowing through different outlets to be consistent, ensuring uniform distribution of water volume in the entire system during irrigation. This design optimizes the water flow balance at each water outlet.

[0045] The outlet pipe changes the trajectory of water flow by a spiral structure, so that it has a weak vortex when leaving the water outlet, thereby compensating for the flow difference caused by the different path lengths of the water flow. Specifically, the spiral outlet pipe is arranged at the lower end of the water tank body, and is installed in a similar manner to the conventional straight-through pipe, but introduces a spiral shape at the end, so that the water flowing through this part can form a slight rotation before leaving. This configuration makes the water flow of each independent water outlet more balanced, further improving the irrigation efficiency and reliability of the system.

[0046] For example, the spiral outlet pipe can be directly injection molded, with regular or irregular thread-like protrusions on the inner wall to enhance the vortex effect. At the same time, during installation, ensure that each spiral pipe has a certain inclination angle with the horizontal plane, to ensure that it does not affect the normal water supply of the main water supply pipeline while also producing the required vortex effect. In addition, in order to maintain the overall stability of the structure, the spiral water outlet pipe also needs to have reasonable connection and fixation measures with the surrounding structure to prevent its working performance from being affected by vibration or other external factors.

[0047] In one embodiment, as shown in Figure 2 The design of a water-saving irrigation water storage tank of the present application further introduces a guide plate 6 as a key component. The guide plate 6 is located below the flow distribution plate 3 and is installed obliquely, so that the water flow can be more smoothly distributed to different water outlet assemblies 4. Specifically, the guide plate 6 can effectively guide the water flow to be evenly distributed inside the water tank through its unique oblique arrangement. Compared with the traditional straight water path, the guide plate 6 realizes a more scientific and reasonable water flow line through the setting of the inclination angle and the selection of the installation position.

[0048] For example, after the water flow enters the water storage tank, it will first pass through the flow distribution plate 3 for preliminary dispersion, and then continue to move along the direction of the guide plate 6 to reach the specified multiple water outlets. Since the guide plate 6 is obliquely arranged below the flow distribution plate 3, it not only guides the water flow passing through the flow distribution plate 3 to smoothly flow into the corresponding water outlets, but also further adjusts the proportion of water distribution. By adjusting parameters such as inclination and length, technicians can flexibly configure the water flow in each direction according to actual irrigation needs, to ensure that water is better dispersed in the entire system and to promote the maximum utilization of water resources without waste.

[0049] In one embodiment, continuing to refer to Figure 2The support rib 5 of the water storage tank for water-saving irrigation of the present application is provided with a scouring protection shield 7 at the top end, which is designed to protect the upper layer of the baffle from damage caused by high-speed water flow, while maintaining the stability and overall performance of the internal component structure. The scouring protection shield 7 is made of a material that is resistant to weathering and wear, ensuring that it will not deform or break even after long-term use. The shield is designed to have a certain curvature and a smooth surface, and is installed at the top end of the support rib 5, at a proper distance from the flow distribution plate 3.

[0050] Specifically, the scouring protection shield 7 is fixed at the top of all support ribs 5, but does not contact the top wall of the water tank. This does not affect the water flow and flow rate change trend of the water flowing into the water tank from the water inlet pipe 2, nor does it hinder the normal circulation of internal air. The presence of the shield can buffer and disperse the damage that the initial high-speed water flow into the water tank may cause to the upper layer components. When the water flow passes through the water inlet pipe 2 and enters the water tank, the scouring protection shield 7 can effectively reduce the local turbulence intensity and make the liquid transition to the downstream components smoothly. For example, the shield edge is designed in a rounded and smooth line shape, reducing the vortex phenomenon caused by sharp corners and the subsequent pressure difference fluctuation. In this way, in actual application, whether facing a large water inflow or a complex water quality, the system can remain in a stable operating state without damaging the key components.

[0051] In one embodiment, as shown in Figure 3 The support rib 5 of the water storage tank for water-saving irrigation of the present application is composed of at least two parallel vertical steel bars, wrapped with a layer of buffer rubber material 8 on the outside. The main function of the support rib 5 is to fix and strengthen the structural strength between the inner wall of the water tank body 1 and the edge of the flow distribution plate 3, thereby ensuring the stability and durability of the system.

[0052] The support rib 5 has special requirements for the installation position. Its top is close to but does not contact the top wall of the water tank, and the bottom is left with a proper distance to ensure sufficient spacing between the tank bottom, without causing any obstruction to the flow path. At the same time, these vertical steel bars are arranged according to the predetermined rules in longitudinal and transverse directions, and the rigidity and perpendicularity of each are maintained by the spacer connectors, making the overall structure more stable and not interfering with the smoothness of the water flow path.

[0053] In specific implementation, in order to protect the inner wall of the water tank and ensure the smoothness of the flow path, all vertical steel bars are completely wrapped with external buffer rubber material. For example, during production, the vertical steel bars are first welded or fixed into shape, then fitted into the pre-made buffer rubber sleeve, and finally assembled to the designated position inside the water tank, and the position and direction of each support rib 5 are calibrated using special tools. This not only achieves the desired reinforcement purpose, but also effectively prevents the inner wall from being scratched or damaged by direct contact with hard metal.

[0054] In one embodiment, the surface of the water distribution plate 3 of the water storage tank for water-saving irrigation is sprayed with a layer of wear-resistant waterproof coating to ensure that it does not deform or crack after long-term use. The application of this layer of wear-resistant waterproof coating effectively protects the surface of the water distribution plate 3 material, preventing deformation or damage under the action of water flow impact and other external forces, thereby ensuring the precise size of the grid structure on the water distribution plate 3 and its uniform water distribution function. This technical treatment helps to improve the durability and stability of the water distribution plate 3, enabling it to maintain excellent performance for a long time.

[0055] For example, various wear-resistant waterproof coating technologies can be used, such as selecting acrylate or epoxy resin with good adhesion, strong water resistance, and good wear resistance as the coating material. During spraying, the entire surface of the water distribution plate 3 should be evenly sprayed, and the coating should be formed into a solid and smooth protective layer through appropriate curing treatment. Specifically, during the surface pretreatment stage of the water distribution plate 3, cleaning and light sanding are required to improve the adhesion of the coating film. Then, the coating is applied according to the specified ratio and method of the manufacturer, and the curing treatment is strictly carried out according to the specified conditions, finally enabling the wear-resistant waterproof coating layer to fully exert its protective performance and ensure long-term stable operation.

[0056] In one embodiment, referring back to Figure 2 One of the design features of the water storage tank for water-saving irrigation is the installation of a floating ball sensor 9 above the water distribution plate 3 to achieve real-time monitoring and automatic adjustment of the water level. The floating ball sensor 9 is installed near the upper region of the water distribution plate 3 and is directly connected to the signal acquisition module of the control system. This layout allows the system to instantly obtain the water surface height information in the water storage tank.

[0057] Specifically, the floating ball sensor 9 has two parts: a sensing component and an execution component. The sensing component floats on the water surface and moves up and down with the fluctuation of the water surface. When the floating ball rises or falls, it triggers the internal mechanical linkage mechanism to change the aperture size of the grid structure. The control system adjusts the action of the execution component based on the preset water level threshold to ensure that the distribution of water flow after passing through the grid structure remains uniform and stable, thereby maintaining the water in the water storage tank within the set range.

[0058] For example, a floating element with adjustable damping device can be used as part of the floating ball, enabling it to respond smoothly to water level changes and reduce oscillation interference; at the same time, a high-precision micro-displacement detector is connected to improve the accuracy of feedback data, and an electronic servo drive system is used to precisely control the electric valve, dynamically adjusting the opening and closing degree of each water outlet, achieving fine control of water flow, and thereby ensuring water level balance under the working state of the entire water storage tank.

[0059] In one embodiment, the water tank body 1 of the water storage tank for water-saving irrigation of the present application is provided with a group of pressure relief holes 10 (see Figure 2 near the bottom of the side wall. When the pressure in the system exceeds the preset safety value, it can automatically vent without causing water overflow. The presence of the pressure relief holes 10 helps maintain the stability of the internal pressure, avoids water flow instability caused by pressure fluctuations, and ensures reliable operation and effective irrigation of the system.

[0060] Specifically, in the design, the group of pressure relief holes 10 is installed at an appropriate height near the bottom end of the side wall of the water tank body 1, ensuring that it can effectively sense and respond to internal pressure changes, and also ensuring that it will not be accidentally opened or closed due to liquid level fluctuations during irrigation. The pressure relief holes 10 in this structure are designed integrally with the water tank body 1, or are fixedly connected to the predetermined position using independent parts. For example, a small-diameter perforated plate made of stainless steel can be used to achieve these functions. It can be directly welded to the outside surface of the tank to ensure firm bonding, and the diameter and spacing of each hole are determined according to the calculation of fluid pressure to optimize air flow characteristics while eliminating the risk of water leakage. In this way, excess pressure can be effectively released without affecting water flow, maintaining the overall stability of the system.

[0061] In one embodiment, the spacing connector of the support rib 5 of the water storage tank for water-saving irrigation of the present application uses a porous ceramic fixing frame 11 (see Figure 3 which filters impurity particles in water using the small gaps in the ceramic material to prevent clogging of the lower water outlet. The support ribs 5 are arranged longitudinally and transversely inside the water tank body 1 between the edge of the flow divider plate 3 and the inner wall of the water tank body 1, serving to stabilize the structure.

[0062] Specifically, the porous ceramic fixing frame 11 is installed at the middle position of the support rib 5 and forms an integral whole with it. The ceramic fixing frame is connected to the support rib 5 by bonding or buckling, etc. The porous nature of the ceramic material determines its high efficiency in filtering. This design effectively blocks larger solid particles and other impurities from entering the lower water flow channel, ensuring unobstructed water outlet and normal operation of the system.

[0063] For example, in actual application, high-strength adhesive can be used to tightly adhere the ceramic fixing frame to the center portion of each support rib 5, so that it is firmly maintained in this position. Alternatively, a design with locking fasteners can be used, so that the ceramic fixing frame can be directly sleeved and locked on the support rib 5, thus achieving a simple and stable assembly method. In addition, the support rib 5 and the ceramic fixing frame maintain a proper spacing, which does not affect the supporting function or hinder the filtering process, ensuring smooth passage of water without additional resistance.

[0064] In one embodiment, as shown in Figure 4 In one embodiment, as shown in

[0065] In one embodiment, as shown in

[0066] In one embodiment, as shown in

[0067] In actual operation, when the device is in use, an external water source enters the interior of the water tank body 1 through the water inlet pipe 2. Subsequently, the water flows through the flow distribution plate 3 installed at the lower portion of the water tank body 1, which is provided with a grid structure formed by a plurality of transversely and longitudinally staggered strip-shaped protrusions, and the aperture gradually decreases from the water inlet side to the water outlet side to adjust the water distribution balance of each region. The water flow treated by the flow distribution plate 3 is then uniformly dispersed through the several independent small-diameter outlet pipe fittings distributed at the lower end of the water tank body 1, achieving full-range uniform coverage of the water outlet. In this process, the support ribs 5 are regularly arranged longitudinally and transversely between the inner wall of the water tank body 1 and the edge of the flow distribution plate 3 to reinforce the structure, and the top end and the bottom end are respectively reserved with appropriate spacing to ensure smooth water flow, while the intermediate spacing connecting piece is used to maintain the structural rigidity and perpendicularity, optimizing the stability of the entire system. Such a structural design allows the water flow to be more uniformly dispersed in the entire water tank, thereby improving the irrigation efficiency and effectively saving water resources.
