[0063] In this embodiment, this embodiment describes in detail a structural design of a submersible centrifugal drip irrigation pump, which has a highly modular, easy-to-maintain and efficient underwater submersible electrical separation structure, and achieves stable and efficient water transmission through a sophisticated hydraulic transmission and regulation mechanism. The pump body is designed as a submersible pump shell, which contains a first installation cavity 101 as an installation space for the motor and related components. The disassembly shell 2 is detachable for easy maintenance and installation, and has a second installation cavity 201, which is combined with the pump body shell 1 to form a tight structure. Located in the second installation cavity 201 of the disassembly shell 2, it provides support for key components for thrust transmission.

[0064] The thrust plate 3 is installed on one side of the thrust seat 4 and is located closer to the pump housing 1. This means that this component of the thrust plate 3 not only serves as a force transmission medium, but its layout also takes into account the directionality of power transmission and the reasonable layout of the overall structure of the pump body. This design is intended to optimize the force transmission path, ensure that the transmission from the power source to the core rotating parts of the pump is more direct and efficient, and reduce energy losses. The layout close to the pump housing 1 also contributes to the stability of the force and the robustness of the overall mechanical structure, reduces vibration, and ensures the stability and efficiency of the pump in long-term operation.

[0065] The pump housing 1 is designed as a core component, the center of which is the cylinder 102, which constitutes the main structural frame of the pump housing 1. The upper guide 103 of the motor and the lower guide 104 of the motor are respectively arranged on both sides of the cylinder 102. The design of the upper guide 103 of the motor and the lower guide 104 of the motor not only serves as a supporting structure for the motor, but also divides different functional spaces. The upper guide 103 of the motor and the lower guide 104 of the motor form a first installation cavity 101 around the cylinder 102, which is mainly used to accommodate the motor and related electrical components to ensure that the electrical parts are isolated from water to ensure safe operation. In addition, a second installation cavity 201 is formed between the lower guide 104 of the motor and the disassembly housing 2, that is, the disassembly side of the disassembly housing 2. This space design is to facilitate the maintenance and assembly of the disassembly housing 2, as well as the installation and adjustment of possible mechanical transmission components such as the thrust plate 3 and the thrust plate 3, etc., to facilitate maintenance and replacement, and improve the overall operability and maintenance convenience of the pump. This design fully considers the special needs of submersible pumps in complex underwater operations, ensuring their reliability and easy maintainability.

[0066] The thrust seat 4 is located on the motor lower guide 104. Its design takes into account two symmetrical fastening grooves. Such a symmetrical layout not only enhances the stability of the structure, but also facilitates installation and adjustment, and provides precise positioning points for subsequent fasteners 5. Several fasteners 5 are used to fasten the thrust seat 4 and the motor lower guide 104 to ensure a stable connection between the two. This not only simplifies the assembly process, but also improves the overall mechanical strength, ensuring that the connection between the thrust seat 4 and the motor lower guide 104 remains firm under vibration or pressure during the operation of the pump body, preventing loosening, and ensuring the stability of the pump body and the reliability of long-term operation.

[0067] The main shaft 6, as the axis of power transmission, is installed between the upper guide 103 of the motor and the lower guide 104 of the motor to ensure the transmission of the motor power. One end thereof passes through the lower guide 104 of the motor and goes deep into the second installation cavity 201. This design is to directly contact the thrust plate 3 to achieve effective power transmission. The thrust plate 3 is placed between the lower guide 104 of the motor and the thrust seat 4, closely following the extension of the main shaft 6. This thrust plate 3 is the key to the conversion of the motor force. It directly receives the rotational force from the motor and transmits it to other moving parts of the pump. The rotor 7 is assembled on the main shaft 6, and the stator 8 is fixed on the inner wall of the cylinder 102, and the two form an electromagnetic coupling system. The rotor 7 generates a change in the magnetic field as the main shaft 6 rotates, and the stator 8 induces an electric field response, converting this energy into mechanical energy, driving the impeller 15 to rotate and pump water. In terms of material, as a preferred option, 470 grade high silicon wafers can be used, and the outer shell is made of stainless steel 304. Sliding bearings are used at the internal rotating connections of the motor upper guide 103 and the motor lower guide 104. The material can be selected from tin bronze and babbitt alloy, which has high hardness, excellent wear resistance and long service life.

[0068] The inner wall of the cylinder 102 is constructed into an annular structure, which not only enhances the rigidity of the cylinder 102, but also provides a stable installation platform for the arrangement of the stator 8. A number of circumferentially arranged wire slots 901 are designed on the annular edge 9. The function of these wire slots 901 is to accurately place the coil 801 of the stator 8, optimize the layout of the electromagnet core, and thus improve the efficiency of the magnetic circuit. The end of the coil 801 is placed in the wire slot 901. Such an arrangement not only makes the wiring of the coil 801 more compact and neat, and is more conducive to heat dissipation, but also ensures the stability of the current flow, improves the electromagnetic conversion efficiency, and ultimately makes the operation of the entire pump body more energy-saving and efficient.

[0069] A pressure regulating membrane 10 is added to the outer wall of the disassembly shell 2 to balance the expansion pressure of the heat dissipating water in the pump. A pressure regulating cavity 12 is formed between this membrane and the outer wall of the disassembly shell 2. This design allows the pressure in the pump to be adjusted to maintain balance and increase the stability of the pump. The through hole 202 on the outer wall of the disassembly shell 2 is connected to the pressure regulating cavity 12, and further connected to the second installation cavity 201, so that the pressure can flow inside and outside, which is convenient for adjustment. The bottom cover 11 is installed on the top of the disassembly shell 2 to compress and protect the pressure regulating die to ensure the stable operation of the pressure system.

[0070] The thrust plate 3 has a thrust hole 301, which enables precise docking with the main shaft 6 to achieve high-efficiency power transmission and bear the pressure of all the lifts of the pump group. Since the thrust plate 3 is directly connected to the main shaft 6, the moving parts of the intermediate parts are reduced, the potential vibration and instability factors are reduced, and the pump is more stable when working.

[0071] The upper guide bracket 13 is located on the upper guide 103 of the motor, playing a supporting role, and the sealing design ensures the isolation of the motor from the external water environment to avoid leakage and corrosion. The pump head 14 is installed on the upper guide bracket 13. As the head of the pump, it has a water inlet 1401 and a water outlet 1402. It is the inlet and outlet of water, realizing the introduction and discharge of water, and is the core interface of the pump. The impeller 15 is placed inside the pump head 14, adopts a full-lift working condition design, and is directly connected to the main shaft 6. The rotation of the impeller 15 drives the water flow, and the momentum of the blades is converted into pressure to promote the flow of water. When the lift is needed, the flow rate becomes the lift, and when the flow rate is needed, the lift becomes the flow rate, which can adapt to various environmental landforms. The water inlet cylinder 16 is added to the pump head 14, with a number of water holes 1601. These holes are evenly arranged along the side of the water inlet cylinder 16 to form a water inlet channel. The water inlet 1401 is connected to the outside world through the water holes 1601, and water can freely enter the cylinder, and then be pushed by the rotation force of the impeller 15 and output through the water outlet 1402, completing the water cycle. At the same time, it has a self-absorption fertilizer function, and fertilizer and water enter the impeller 15 synchronously through the water holes 1601. The rotation and stirring of the impeller 15 can improve the mixing degree of fertilizer and water, thereby improving the irrigation quality.

Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
