Description

Technical Field

[0001] This utility model relates to the field of power generation equipment technology, and in particular to a portable water flow generator. Background Technology

[0002] During outdoor camping, a reliable power supply is crucial. While electronic devices have become necessities in daily life, their battery life is generally short; for example, a mobile phone typically needs charging once a day. Furthermore, existing batteries have limited storage capacity. When both electronic devices and batteries are depleted during camping, it not only severely impacts the enjoyment of the trip but may also pose safety risks due to loss of navigation functionality. Therefore, a portable power generation device suitable for outdoor camping scenarios is urgently needed. However, existing power generation devices have many shortcomings and are difficult to meet the needs of outdoor camping. Moreover, most power generation devices have high environmental requirements. For example, solar power generation devices not only have low power generation efficiency, but are also quite demanding in terms of weather conditions, and cannot generate power normally on cloudy or rainy days. Diesel generators, on the other hand, can generate enough power to meet the needs, but they are bulky and heavy, making them inconvenient to carry. They also produce a lot of noise when operating, and the combustion of chemical fuels can pollute the environment. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a portable water flow generator to solve the power supply problem during outdoor camping and meet the power needs of electronic devices in outdoor camping scenarios.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A portable water flow generator includes a bracket, a circulating water cylinder installed inside the bracket, a rotating shaft rotatably installed inside the circulating water cylinder, double helical blades installed around the rotating shaft, a generator installed on the top of the bracket, and the power output end of the rotating shaft connected to the rotating main shaft of the generator through a transmission mechanism.

[0005] Furthermore, it also includes a gearbox, with the rotating shaft connected to the input shaft of the gearbox via a transmission mechanism, and the output shaft of the gearbox connected to the rotating main shaft of the generator via a coupling.

[0006] Furthermore, an outwardly expanding container is fitted onto the side of the circulating water cylinder located at the power input end of the rotating shaft.

[0007] Furthermore, the transmission mechanism includes a driving sprocket and a driven sprocket. The driving sprocket is mounted on the power output end of the rotating shaft, and the driven sprocket is mounted on the input shaft of the gearbox. The driving sprocket and the driven sprocket are driven by a chain.

[0008] Furthermore, the gearbox includes a housing, within which an input shaft and an output shaft are mounted. The input and output shafts are rotatably mounted within the housing via bearings and are arranged relatively parallel to each other. One end of the input shaft passes through the side wall of the housing and is fitted with a driven sprocket. A first pinion and a first gear are sequentially fixedly mounted on the input shaft. One end of the output shaft passes through the side wall of the housing and is connected to the rotating main shaft of the generator via a coupling. The middle section of the output shaft is prism-shaped, and the two side sections of the middle section are cylindrical. A second gear and a second pinion are respectively mounted on the cylindrical side sections. The second gear meshes with the first pinion. The transmission ratio between the two is 1. The second pinion meshes with the first large gear, and the transmission ratio between them is 3. It also includes a drive wheel and a shift fork. The middle part of the drive wheel has a through hole that matches the prism of the middle section of the output shaft. The drive wheel is slidably mounted on the middle section of the output shaft through the through hole. Several positioning rods are distributed in a ring on the front and rear end faces of the drive wheel. The end faces of the second large gear and the second pinion have positioning holes corresponding to the positions of the positioning rods on the drive wheel. The outer circle of the drive wheel has a sliding groove. One end of the shift fork is slidably set in the sliding groove, and the other end of the shift fork is vertically connected to a stop bar. The free end of the stop bar passes through the side wall of the housing and is connected to a handle.

[0009] Furthermore, a filter screen is fitted to the head of the expansion container.

[0010] Compared with the prior art, the beneficial effects of this utility model are: compared with some existing devices with low power generation efficiency, the combination of double helix blades and rotating shaft can make fuller use of the kinetic energy of water flow. When water flow acts on double helix blades, the double helix structure can make the blades rotate more stably and efficiently under the push of water flow, thereby driving the rotating shaft to rotate with higher efficiency. After the power is transmitted to the generator through the transmission mechanism, the power generation efficiency can be effectively improved, and the power demand of multiple electronic devices during outdoor camping can be better met. The gearbox can adjust its speed according to the actual water flow conditions, enabling the generator to reach the effective power generation speed under different water flow speed conditions, eliminating the strict specific requirements for water flow drop and providing applicability. The expansion tank allows a wider range of water flow to be gathered and introduced into the circulating water tank, enabling more water flow to act on the double helix blades, thereby providing greater power to the double helix blades, further improving the rotation efficiency of the shaft, and thus improving the power generation efficiency of the generator. At the same time, it reduces the dependence on conditions such as the width of the water flow. Attached Figure Description

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0014] A portable water flow generator includes a support frame 3, a circulating water cylinder 2 installed inside the support frame 3, a rotating shaft rotatably mounted inside the circulating water cylinder 2, and double helical blades 4 mounted around the rotating shaft. A generator 9 is mounted on the top of the support frame 3. The power output end of the rotating shaft is connected to the rotating main shaft of the generator 9 via a transmission mechanism. The circulating water cylinder 2 provides space for water flow. The double helical blades 4 mounted on the rotating shaft cause the rotating shaft to rotate by the water flow impacting the double helical blades 4. The power is then transmitted to the rotating main shaft of the generator 9 through the transmission mechanism to generate electricity.

[0015] It also includes a gearbox 7, with the rotating shaft connected to the input shaft 703 of the gearbox 7 via a transmission mechanism. The output shaft 710 of the gearbox 7 is connected to the rotating main shaft of the generator 9 via a coupling 8. The gearbox 7 can adjust its speed according to the actual water flow conditions. When the water flow speed is slow, resulting in a low shaft speed, the gearbox 7 can increase the speed of the input shaft 703 to a high speed of the output shaft 710, which is then transmitted to the rotating main shaft of the generator 9, enabling the generator 9 to achieve an effective power generation speed under different water flow speed conditions.

[0016] The circulating water cylinder 2 located at the power input end of the rotating shaft is fitted with an outwardly expanding container 1, which can gather and introduce a wider range of water flow into the circulating water cylinder 2, so that more water flow acts on the double helix blades 4, thereby providing greater power to the double helix blades 4, further improving the rotation efficiency of the rotating shaft, and thus improving the power generation efficiency of the generator 9, while also reducing the dependence on conditions such as water flow width.

[0017] The transmission mechanism includes a drive sprocket 501 and a driven sprocket 503. The drive sprocket 501 is mounted on the power output end of the rotating shaft, and the driven sprocket 503 is mounted on the input shaft 703 of the gearbox 7. The drive sprocket 501 and the driven sprocket 503 are driven by a chain 502.

[0018] The gearbox 7 includes a housing 715, within which an input shaft 703 and an output shaft 710 are mounted. The input shaft 703 and output shaft 710 are rotatably mounted within the housing 715 via bearings 701, and are arranged relatively parallel to each other. One end of the input shaft 703 passes through the side wall of the housing 715 and is fitted with a driven sprocket 503. A first pinion 702 and a first gear 704 are sequentially fixedly mounted on the input shaft 703. One end of the output shaft 710 passes through the side wall of the housing 715 and is connected to the rotating main shaft of the generator 9 via a coupling 8. The middle section of the output shaft 710 is prismatic, and the two side sections are cylindrical. A second gear 709 and a second pinion 706 are respectively mounted on the cylindrical side sections. The second gear 709 meshes with the first pinion 702. The transmission ratio is 1. The second pinion 706 meshes with the first large gear 704, and the transmission ratio between them is 3. It also includes a power wheel 708 and a shift fork 707. The power wheel 708 has a through hole in the middle that matches the prism of the middle section of the output shaft 710. The power wheel 708 is slidably mounted on the middle section of the output shaft 710 through the through hole. Several positioning rods 712 are distributed in a ring on the front and rear end faces of the power wheel 708. The end faces of the second large gear 709 and the second pinion 706 have positioning holes 713 corresponding to the positions of the positioning rods 712 on the power wheel 708. The outer circle of the power wheel 708 has a sliding groove 714. One end of the shift fork 707 is slidably disposed in the sliding groove 714. The other end of the shift fork 707 is vertically connected to a stop bar 711. The free end of the stop bar 711 passes through the side wall of the housing 715 and is connected to a handle 705. The lever 711 is driven by the movable handle 705, which in turn drives the shift fork 707. The shift fork 707 pushes the power wheel 708 to slide in the middle section of the output shaft 710, allowing the positioning pin 712 on the power wheel 708 to insert into the positioning hole 713 of the second large gear 709 or the second small gear 706, thereby achieving the switching of different transmission ratios. When the outdoor water flow speed is fast and the shaft speed is high, the transmission ratio can be switched to 1 (the second large gear 709 meshes with the first small gear 702), making the output shaft 710 speed comparable to the input shaft 703 speed, thus preventing the generator 9 from being damaged by excessive speed. When the water flow speed is slow and the shaft speed is low, the transmission ratio can be switched to 3 (the second small gear 706 meshes with the first large gear 704), increasing the output shaft 710 speed through the speed-increasing effect, ensuring that the generator 9 can reach the effective power generation speed. This switchable transmission ratio structure can flexibly adapt to different water flow speed conditions, further reducing the device's dependence on water flow conditions. It solves the problem of unstable power generation or inability to generate electricity when the water flow speed changes in existing water flow power generation devices, while also protecting the generator 9 and extending the device's service life.

[0019] A filter screen 10 is fitted to the head of the expansion container 1.

[0020] In use, place the portable water generator beside the stream and adjust the bracket 3 to position the circulating water cylinder 2 at a suitable angle to ensure that the water can smoothly enter the expansion container 1. After being filtered by the filter screen 10, the water enters the expansion container 1 and then flows into the circulating water cylinder 2, impacting the double helix blades 4 and causing the double helix blades 4 and the rotating shaft to rotate. The rotating shaft drives the drive sprocket 501 to rotate, and the drive sprocket 501 drives the driven sprocket 503 to rotate via the chain 502, which in turn drives the input shaft 703 of the gearbox 7 to rotate.

[0021] If the water flow is slow, the operator holds the handle 705 and pushes the lever 711. The lever 711 moves the shift fork 707, which pushes the power wheel 708 towards the second pinion 706, causing the positioning rod 712 on the power wheel 708 to insert into the positioning hole 713 of the second pinion 706. At this time, the first large gear 704 on the input shaft 703 drives the second pinion 706 to rotate. The second pinion 706 drives the output shaft 710 to rotate through the power wheel 708. The transmission ratio is 3, and the speed of the output shaft 710 increases, thereby driving the generator 9 to rotate at high speed to ensure power generation efficiency.

[0022] If the water flow is fast, the operator pulls the handle 705, which moves the lever 711 and shift fork 707, causing the power wheel 708 to slide towards the second large gear 709. The positioning rod 712 on the power wheel 708 is inserted into the positioning hole 713 of the second large gear 709. At this time, the first small gear 702 on the input shaft 703 drives the second large gear 709 to rotate. The second large gear 709 drives the output shaft 710 to rotate through the power wheel 708. The transmission ratio is 1, and the output shaft 710 rotates at a suitable speed to avoid damage to the generator 9 due to excessive speed.

[0023] After generating electricity, generator 9 can be connected to power banks, mobile phones and other electronic devices via wires to charge them, meeting the power needs of outdoor camping.
