[0002] Currently, there is a growing demand for portable hydroelectric power generation devices in scenarios such as outdoor emergency power supply and field operations. However, existing such devices typically employ a fixed structural design, and their overall height and the location of the power generation unit cannot be flexibly adjusted according to the actual aquatic environment.

[0003] In practical applications, the depth and shoreline topography of natural water bodies such as rivers and streams are complex and varied. Due to the lack of effective adjustment capabilities, it is difficult to quickly and stably place the water energy capture components in the optimal position of the water flow, resulting in low energy capture efficiency or even failure to function properly.

[0004] To address the problems raised in the background art, those skilled in the art have proposed a portable hydroelectric micro-device. Summary of the Invention

[0005] The purpose of this invention is to provide a portable hydroelectric power generation micro-device to solve the problems in the prior art where the fixed structure results in a lack of height adjustment capability, making it difficult to adapt to different water depth environments and causing low energy capture efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a portable hydroelectric power generation micro-device, including a support frame, an adjustment component on the top of the support frame for adjusting the height of the device, an upper support fixedly connected to the top of the adjustment component, a lower support fixedly connected to the top of the support frame, and a hydroelectric conversion mechanism on the top of the lower support for converting potential energy.

[0007] Preferably, the adjusting assembly includes a connecting screw sleeve, which is fixedly connected to the outer side wall of the support frame, and a connecting screw is threadedly connected to the inner side wall of the connecting screw sleeve. An adjusting slide rod is also slidably connected to the inner side wall of the support frame.

[0008] Preferably, the surface of the adjusting slide rod is provided with multiple sets of limiting grooves, and the multiple sets of limiting grooves are also engaged with the connecting screw. The bottom end of the upper bracket is fixedly connected to the adjusting slide rod.

[0009] Preferably, the hydraulic conversion mechanism includes a limiting sleeve, which is fixedly connected to the top of the lower support. A connecting shaft is inserted into the inner wall of the limiting sleeve. One end of the connecting shaft is fixedly connected to an outer limiting disc. A connecting screw groove is opened on the outer wall of the other end of the connecting shaft. A limiting screw sleeve is threadedly connected to the outer wall of the connecting screw groove.

[0010] Preferably, a first transmission wheel and a second transmission wheel are fixedly connected to the outer side wall of the connecting shaft, and a plurality of transmission fan blades are fixedly connected to the outer side wall of the second transmission wheel for connecting with the water flow.

[0011] Preferably, a power management unit is installed on the top of the upper bracket, and a drive shaft is fixedly connected to the output end of the power management unit. A driven wheel is also fixedly connected to the outer wall of the drive shaft, and a drive belt is provided between the driven wheel and the limiting screw sleeve for transmission.

[0012] Preferably, the outer side wall of the upper bracket is provided with a power conduction mechanism, the outer side wall of the upper bracket is fixedly connected with a connection slot, the inner side wall of the connection slot is installed with a connection plug for conducting power, the outer side wall of the connection plug is fixedly connected with a sealing gasket, the sealing gasket is sleeved on the outer side wall of the connection slot, and the rear end of the connection plug is installed with a transmission wire for conducting power.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model achieves flexible, multi-level adjustment of the overall height of the device by setting an adjustment assembly consisting of a connecting screw sleeve, a connecting screw rod, an adjusting slide rod, and multiple sets of limiting grooves. Users can easily rotate the connecting screw rod to engage or disengage it with the limiting grooves at different positions, thereby driving the upper support to rise or fall. This allows the water energy capture component to quickly adapt to different water depths, ensuring that the drive fan blades are always in the optimal position for water flow, significantly improving energy capture efficiency and power generation stability.

[0015] 2. This utility model effectively resolves the contradiction between portability and functionality by adopting a modular and detachable hydraulic conversion mechanism design. The connecting shaft is fixed by a limiting screw sleeve, a connecting screw groove, and an outer limiting plate, allowing for easy installation and removal of the transmission wheel and fan blades. During transportation, the entire hydraulic conversion section can be disassembled and stored, greatly reducing the size of the device. This structure, while ensuring power generation, significantly improves the portability and transportation safety of the device.

[0016] 3. This utility model ensures the sealing and safety of the power output interface by setting a power conduction mechanism consisting of a connection slot with a sealing gasket and a connection plug.

Detailed Implementation

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] As attached Figure 1 To be continued Figure 5 As shown:

[0027] Example 1: This utility model provides a portable hydroelectric power generation micro device, including a support frame 1. The top of the support frame 1 is provided with an adjustment component for adjusting the height of the device. The top of the adjustment component is fixedly connected to an upper bracket 11. The top of the support frame 1 is fixedly connected to a lower bracket 12. The top of the lower bracket 12 is also provided with a hydraulic conversion mechanism for converting potential energy.

[0028] During operation, the staff first fixes the support frame 1 to the riverbed or bank, and then adjusts the height of the upper support 11 by adjusting the components, thereby adjusting the position of the hydraulic conversion mechanism relative to the water surface. The water flow impacts the hydraulic conversion mechanism, converting its kinetic energy into mechanical energy, which is then used to drive the power generation unit on the upper support 11 to generate electricity through the transmission system. Through this basic workflow, the goal of efficiently capturing water energy and generating electricity in different water depth environments is achieved.

[0029] 1. In one embodiment of the present invention, the adjusting component includes a connecting screw sleeve 2, which is fixedly connected to the outer side wall of the support frame 1. A connecting screw 21 is threadedly connected to the inner side wall of the connecting screw sleeve 2, and an adjusting slide rod 22 is slidably connected to the inner side wall of the support frame 1.

[0030] During operation, the operator first tightens the connecting screw 21. Since the connecting screw 21 and the connecting sleeve 2 are threaded, rotation will cause the connecting screw 21 to undergo axial displacement. Through the engagement between the end of the connecting screw 21 and the upper limit groove 23 of the adjusting slide 22, the adjusting slide 22 is pushed or pulled to slide up or down within the support frame 1, thereby achieving stepless and continuous height adjustment. The operation is simple, stable, and reliable.

[0031] 2. In one embodiment of the present invention, the surface of the adjusting slide rod 22 is provided with multiple sets of limiting grooves 23, and the multiple sets of limiting grooves 23 are also engaged with the connecting screw 21. The bottom end of the upper bracket 11 is fixedly connected to the adjusting slide rod 22.

[0032] During operation, after the operator roughly positions the height by rotating the connecting screw 21, the end of the connecting screw 21 can be precisely engaged into any of the limiting slots 23. Through this ratchet-type engaging structure, a strong mechanical self-locking force is provided for the adjusting slide 22, effectively preventing it from sliding down on its own under the impact of water flow or vibration, thus ensuring the high stability and safety of the power generation unit during operation.

[0033] 3. In one embodiment of the present invention, the hydraulic conversion mechanism includes a limiting sleeve 13, which is fixedly connected to the top of the lower support 12. A connecting shaft 14 is inserted into the inner side wall of the limiting sleeve 13. An outer limiting plate 19 is fixedly connected to one end of the connecting shaft 14. A connecting screw groove 141 is opened on the outer side wall of the other end of the connecting shaft 14. A limiting screw sleeve 15 is threadedly connected to the outer side wall of the connecting screw groove 141.

[0034] During operation, the operator first inserts the connecting shaft 14, which contains the first transmission wheel 16, the second transmission wheel 161, and the transmission fan blade 162, into the limiting sleeve 13. Then, the limiting screw sleeve 15 is tightened onto the connecting screw groove 141, axially pressing and fixing the connecting shaft 14 between the outer limiting plate 19 and the limiting screw sleeve 15. This "two-end clamping" fixing method ensures that the connecting shaft 14 can rotate flexibly without coming out of the limiting sleeve 13. The structure is simple, and assembly and disassembly are very convenient.

[0035] 4. In one embodiment of the present invention, a first transmission wheel 16 and a second transmission wheel 161 are fixedly connected to the outer side wall of the connecting shaft 14, and a plurality of transmission fan blades 162 are fixedly connected to the outer side wall of the second transmission wheel 161 for connecting with the water flow.

[0036] During operation, the operator first places the device in flowing water. The water flow impacts the transmission fan blade 162, thereby driving the transmission wheel 161 and the entire connecting shaft 14 to rotate. Through the coaxial fixing of the transmission wheel 161 and the transmission wheel 161, the kinetic energy of the water flow is efficiently converted into the mechanical rotational kinetic energy of the connecting shaft 14, providing a continuous power input for subsequent power generation.

[0037] 5. In one embodiment of the present invention, a power management unit 18 is installed on the top of the upper bracket 11, and a drive shaft 181 is fixedly connected to the output end of the power management unit 18. A driven wheel 182 is also fixedly connected to the outer side wall of the drive shaft 181, and a drive belt 183 is provided between the driven wheel 182 and the limiting screw sleeve 15 for transmission.

[0038] During operation, the operator first connects the limiting screw sleeve 15 (power input end) and the driven wheel 182 via the transmission belt 183. The rotational power of the connecting shaft 14 is transmitted to the transmission shaft 181 via the transmission belt 183, driving it to rotate at high speed. The transmission shaft 181 is actually the rotor part of the permanent magnet brushless DC generator. The power management unit 18 internally contains the generator's stator coils, rectifier bridge (such as MB6S), voltage regulator chip (such as TP4056 charging management chip), and USB output interface (such as USB-A female connector). When the transmission shaft 181 rotates, the stator coils cut magnetic lines of force to generate alternating current, which is rectified into direct current by the rectifier bridge, then regulated and charged by the voltage regulator chip, and finally outputs 5V DC power from the USB interface. Through this integrated design, mechanical energy is efficiently converted into stable and usable USB power to charge external devices or the built-in battery.

[0039] 6. In one embodiment of the present invention, the outer side wall of the upper support 11 is provided with a power conduction mechanism, the outer side wall of the upper support 11 is fixedly connected with a connecting slot 3, the inner side wall of the connecting slot 3 is installed with a connecting plug 31 for conducting power, the outer side wall of the connecting plug 31 is fixedly connected with a sealing gasket 32, the sealing gasket 32 ​​is sleeved on the outer side wall of the connecting slot 3, and the rear end of the connecting plug 31 is installed with a transmission wire 33 for conducting power.

[0040] During operation, the operator first inserts the connector 31 into the connector slot 3. At this time, the sealing gasket 32 ​​elastically deforms, tightly wrapping around the outside of the connector slot 3, forming a waterproof barrier. This structure ensures that the power output interface maintains good sealing even when exposed to a humid environment for extended periods or accidentally splashed with water, effectively preventing short circuits and oxidation, and improving the safety and durability of the device. The other end of the transmission line 33 can be connected to an energy storage device (such as a power bank) or an electrical appliance.

[0041] Working principle: When this device is needed, place the entire device in the water flow position. The water flow will first exert a force on the drive fan blade 162, causing it to rotate the drive wheel 161. The rotation of the drive wheel 161 will cause the connecting shaft 14 to rotate as well. The rotation of the connecting shaft 14 will simultaneously rotate the drive wheel 16. The rotation of the drive wheel 16 will then drive the driven wheel 182 via the drive belt 183. The driven wheel 182 will then drive the drive shaft 181 to rotate. The rotation of the drive shaft 181 will transmit potential energy to the power management unit 18, which will convert this potential energy into electrical energy. The transmission line 33 transmits the data for storage. If the device needs to be transported, first remove the sealing gasket 32 ​​and the connecting plug 31 from the outside of the connecting slot 3. Then, rotate the limiting screw sleeve 15 out of the external thread of the connecting screw groove 141. Then, slide the connecting shaft 14 to the side of the outer limiting plate 19. Remove the first transmission wheel 16 and the second transmission wheel 161 on the outside of the connecting shaft 14. Completely remove the connecting shaft 14. Then, rotate the connecting screw 21 so that the connecting screw 21 rotates out of the internal thread of the connecting screw sleeve 2. Next, slide the adjusting slide rod 22 downward with the limiting groove 23 to adjust the size of the entire device, making it convenient to store and transport the entire device.

[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
