Description

Technical Field

[0001] The utility model relates to the technical field of micro hydraulic generators, and more specifically to a double-inlet and outlet type housing for a micro hydraulic generator. Background Art

[0002] In the field of micro hydraulic generators, the design of the housing plays a key role in improving the power generation efficiency, enhancing the stability and durability of the equipment. For traditional micro hydraulic generators, such as a design described in the comparative document CN201910376829.4, its housing mainly adopts a single-inlet and outlet mode, that is, water mainly enters and exits through the top of the housing. This design is relatively simple in structure, but has obvious limitations in practical applications;

[0003] First of all, the single-inlet and outlet design restricts the effective utilization range of water flow. In the natural environment, the direction and intensity of water flow often change. The single design cannot fully capture the water flow energy from the side or other directions, resulting in a reduction in power generation efficiency. In addition, this design also ignores the kinetic energy difference that may occur when water flows through different directions, further restricting the excavation of power generation potential;

[0004] Secondly, there are also deficiencies in the assembly method at the inlet and outlet ends of the micro hydraulic generator in the comparative document. Although the snap-fit method it adopts simplifies the installation process, it is prone to looseness or even detachment when facing strong water flow impact. This will not only affect the normal operation of the generator, but may also cause damage to the equipment, increasing the maintenance cost and safety risk. Summary of the Utility Model

[0005] The purpose of the present utility model is: in order to overcome the deficiencies in the above comparative document and improve the comprehensive performance of the micro hydraulic generator, the present utility model proposes a double-inlet and outlet type housing for a micro hydraulic generator.

[0009] An annular convex block is provided at the top of the housing, and the annular convex block is located between two adjacent curved grooves;

[0010] The cap structure includes a curved block and a cap body;

[0011] The cap body is provided with curvilinear clamping blocks that are engaged and matched with the curvilinear clamping grooves and have the same quantity.

[0013] The cap body is provided with a groove that is engaged and matched with the annular convex block.

[0014] A through hole is provided in the middle of the cap body.

[0015] As a preferred technical solution of the present utility model, a bracket is provided in the through hole, a top cap is provided in the middle of the top of the bracket, and an opening is provided at the top of the top cap.

[0042] The principle of the double-inlet and outlet housing for the micro hydraulic generator proposed by the present utility model is mainly based on the principle of water flow dynamics and the optimization of mechanical structure design. The following is a detailed explanation of the housing principle:

[0043] 1. Water flow introduction and energy conversion

[0044] Double-inlet and outlet design: The curved grooves evenly arranged along the circumferential direction at the top of the housing and the curved blocks on the sealing cap structure together form a double-inlet and outlet water flow channel. This design allows water flow to enter the interior of the housing from both the top and the side simultaneously, increasing the water flow through-put and improving the utilization rate of water flow energy;

[0045] Function of the rotating blade: A rotating blade is provided inside the housing. When water flow passes through, it will drive the rotating blade to rotate. The rotating blade converts the kinetic energy of the water flow into electrical energy through the activity of cutting magnetic induction lines (although the internal structure of the generator is not directly mentioned in this description, usually the rotating blade is connected to the generator rotor to generate electrical energy);

[0046] 2. Mechanical structure stability and sealing performance

[0047] Cooperation between the groove and the block: The mutual clamping cooperation between the curved groove and the curved block, and the design that the depth of the groove is greater than the height of the block ensure the firm connection between the sealing cap structure and the housing. This design not only improves the overall strength of the housing but also enhances its anti-detachment ability under water flow impact;

[0048] Cooperation between the annular protrusion and the groove: The groove on the main body of the sealing cap and the annular protrusion on the top of the housing are mutually clamped and matched, further enhancing the sealing and stability of the housing. This design prevents water flow from leaking at the housing joint and ensures the normal operation of the internal generator components;

[0049] 3. Optimization of the internal structure

[0050] Design of the bracket and the top cap: The cross-shaped bracket arranged in the through hole, the top cap and the opening design in the middle of the top of the bracket provide a firm support structure for the internal generator components. This design helps to reduce the vibration and noise during the operation of the generator and improves the stability and reliability of the equipment;

[0051] Annular groove: The annular groove design on the top of the main body of the sealing cap not only enhances the aesthetics of the sealing cap but also may improve the heat dissipation performance of the housing to a certain extent. Although the heat dissipation function is not directly mentioned in this description, in practical applications, reasonable heat dissipation design is of great significance for extending the service life of the generator and improving the power generation efficiency;

[0052] 4. Application of the thread design

[0053] Thread design on the outer surface of the middle part of the housing: This design facilitates the connection and fixation of the housing to other components. During actual installation and maintenance, the housing can be firmly connected to the generator base or other support structures through threaded connectors, ensuring the stability and safety of the entire generator set;

[0054] In summary, the double-inlet and outlet housing for the micro hydropower generator proposed by the present utility model improves the power generation efficiency and operation stability of the micro hydropower generator through measures such as optimizing the water flow channel design, enhancing the stability and sealing performance of the mechanical structure, optimizing the internal structure, and applying thread design.

[0062] 3. Optimization of the internal structure

[0063] Bracket and top cap design: The cross-shaped bracket arranged in the through hole, the top cap in the middle of the bracket top and the opening design provide a stable support structure for the internal generator assembly. This design helps to reduce the vibration and noise of the generator during operation, and improves the stability and reliability of the equipment;

[0064] Annular groove: The annular groove design on the top of the cap body not only enhances the aesthetics of the cap, but also may improve the heat dissipation performance of the housing to a certain extent.
