Description

Technical Field

[0001] The present application relates to the field of energy harvesting technology, and in particular to an energy harvesting method and device based on a waterfall structure. Background Art

[0002] In recent years, exploitable water resources have become increasingly scarce. Dam construction requires the selection of a suitable geographical location to reduce its impact on the surrounding environment and biological populations. Development is becoming increasingly difficult and costly. Therefore, seeking economically exploitable water resources and minimizing the impact of hydropower on the environment are factors that need to be considered in future hydropower generation.

[0003] At present, there are studies on power generation from rainwater falling from roofs and gray water falling from high-rise buildings. However, the natural rainfall process and rainfall amount are highly random and uncertain, and the amount of gray water is also unstable. It is necessary to break through the traditional sewage plant tailwater recycling strategy that focuses on water resource recovery, coordinate the comprehensive assessment of water quality, water quantity, and water energy, greatly expand the field of sewage plant tailwater recycling, and especially tap the kinetic energy and potential energy of sewage plant tailwater.

[0004] For example, the Chinese patent with publication number CN112228267A (publication date 2021-01-15). In this case, sewage flows through a rotating water wheel, driving the water wheel blades to rotate. The driving rotating shaft of the water wheel is connected to a generator to convert hydraulic energy into electrical energy. However, the rotating structure of the rotating water wheel means that the waterfall can only pass through a single water wheel of the rotating water wheel once. The rotating water wheel cannot perform multi-stage treatment on the waterfall, and the treatment of the waterfall is relatively simple, which consumes a lot of water.

[0005] It should be noted that the above information disclosed in this background technology section is only used to understand the background technology of the present invention concept, and therefore may contain information that does not constitute prior art. Summary of the invention

[0017] If the collecting wheel structures are required to completely block the medium to collect all the energy, the positions of the multiple collecting wheel structures are adjusted so that the entirety of the multiple collecting wheel structures is located at the second position;

[0018] If the collecting wheel structure is not needed to block the medium, the positions of the multiple collecting wheel structures are adjusted so that the entirety of the multiple collecting wheel structures is located at the third position;

[0033] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0034] Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of this application.

[0035] Example 1

[0036] like Figures 1 to 6 As shown, the energy harvesting device based on the waterfall structure described in the embodiment of the present application includes a device frame 1, and a medium channel 2 for forming a drop in the height direction and guiding the medium to pass can be formed on the device frame 1 by means including but not limited to turning. In this embodiment, one end opening of the medium channel 2 is formed on the upper surface of the device frame 1, and the other end opening of the medium channel 2 is formed on the lower surface of the device frame 1, and the medium channel 2 extends continuously inside the device frame 1. A collection wheel accommodating chamber 3 can be formed on the device frame 1 by means including but not limited to turning, and the collection wheel accommodating chamber 3 is arranged on the side of the medium channel 2 along the extension direction of the medium channel 2.

[0037] It is easy to understand that the medium (including but not limited to water) enters the medium channel 2 from the upper side of the medium channel 2 and leaves the medium channel 2 from the lower side of the medium channel 2, and the multiple and repeated energy collection processes can be completed inside the medium channel 2. The formation of the collection wheel accommodating cavity 3 can help the collection wheel to select more positions, and accordingly, can help the medium pass through the medium channel 2 without loss.

[0038] The energy collection device based on the waterfall structure described in the embodiment of the present application also includes a plurality of collection wheel structures 4, and the collection wheel structure 4 is dynamically connected to a power generation unit 5 for continuously generating electricity during the process of the medium passing through and rotating the collection wheel structure 4. In this embodiment, the shell of the power generation unit 5 can be fixedly connected to the end of the collection wheel frame 6 away from the collection wheel body 41 by means including but not limited to bolt connection, and the power generation unit 5 can be electrically connected to the power storage device through a wire or directly connected to the power grid.

[0039] It is easy to understand that the medium continuously passes through multiple collection wheel structures 4 under the action of gravity, and the collection wheel structure 4 continuously rotates under the impact of the medium and drives the power generation unit 5 to continuously generate electricity. It is worth noting that the power generation of the collection wheel structure 4 and the power generation unit 5 per unit time is different at different positions.

[0040] The device frame 1 may also be formed with a plurality of device slideways 7 for guiding the collection wheel structure 4 to change position by means including but not limited to turning, the collection wheel structure 4 is slidably connected to the device slideways 7, and the plurality of device slideways 7 are arranged at intervals along the extension direction of the medium channel 2. In this embodiment, the extension direction of the device slideway 7 is arranged perpendicular to the extension direction of the medium channel 2, and the end of the device slideway 7 extends into the collection wheel accommodating chamber 3. The collection wheel structure 4 includes a collection wheel body 4 and a collection wheel frame 6, the collection wheel body 41 is rotatably connected to the collection wheel frame 6, and the collection wheel frame 6 is slidably connected to the device slideway 7.

[0041] It is easy to understand that the collecting wheel frame 6 supports and guides the collecting wheel body 41 to rotate. The collecting wheel frame 6 can adjust the collecting wheel body 41 to enter the collecting wheel accommodating cavity 3 during the sliding process of the device. The collecting wheel frame 6 can adjust the overlapping or misalignment of adjacent collecting wheel bodies 41 during the sliding process of the device, so as to realize the flexible adjustment of the position of the collecting wheel body 41.

[0042] In this embodiment, a plurality of first impact grooves 42 may be formed on the peripheral side surface of the collection wheel body 41 by means including but not limited to turning processing. The medium impacts the plurality of first impact grooves 42 in turn during the process of passing through the collection wheel body 41, so that the collection wheel body 41 rotates continuously. A second impact groove 61 may be formed at one end of the collection wheel frame 6 facing the collection wheel body 41 by means including but not limited to turning processing. The second impact groove 61 may guide the medium to flow toward the first impact groove 42, thereby increasing the impact force of the medium on the collection wheel body 41, thereby improving the utilization rate of the medium and increasing the power generation.

[0043] It is worth noting that the collection wheel structures 4 arranged in two adjacent device slideways 7 have a first position that overlaps with each other. At the first position, the collection wheel structure 4 blocks part of the medium. The first position serves as the normal position of the collection wheel body 41. It can convert part of the potential energy of the medium into electrical energy without affecting the normal flow of the medium, thereby realizing the power generation function based on the energy collection device based on the waterfall structure.

[0044] It is worth noting that the collection wheel structure 4 arranged in two adjacent device slideways 7 also has a second position that is staggered from each other. In the second position, the collection wheel structure 4 blocks all the medium. The second position serves as the power generation position of the collection wheel body 41, which can improve the ability to convert the potential energy of the medium into electrical energy, and realize the stronger power generation function of the energy collection device based on the waterfall structure while slowing down the flow speed of the medium.

[0045] It is worth noting that the collection wheel structure 4 arranged in two adjacent device slideways 7 also has a third position separated from each other. In the third position, the collection wheel structure 4 does not block the medium. The third position serves as a standby position of the collection wheel body 41, which can realize the free flow of the medium.

[0046] In particular, the collecting wheel structure 4 also has a fourth position of a partial normal position and a partial standby position. In the fourth position, a part of the collecting wheel body 41 converts part of the potential energy of the medium into electrical energy without affecting the normal flow of the medium, and the other part of the collecting wheel is on standby.

[0047] It is easy to understand that the control of the power generation unit 5 can be either automatic control using a controller or manual control under human intervention. The specific control method can be adjusted and implemented in real time by those skilled in the art according to specific circumstances, and will not be repeated in this embodiment.

[0050] In the first position, all the collection wheel structures 4 are moved into the medium channel 2, and the collection wheel structures 4 arranged on two adjacent device slideways 7 are arranged to overlap each other along the projection of the extension direction of the medium channel 2. The first position is the normal position of the collection wheel body 41, which can convert part of the potential energy of the medium into electrical energy without affecting the normal flow of the medium, thereby realizing the power generation function based on the energy collection device based on the waterfall structure.

[0051] In the second position, all the collection wheel structures 4 are moved into the medium channel 2, and the collection wheel structures 4 arranged on two adjacent device slideways 7 are mutually staggered along the projection of the extension direction of the medium channel 2. The second position is used as the power generation position of the collection wheel body 41, which can improve the ability to convert the potential energy of the medium into electrical energy, and realize the stronger power generation function of the energy collection device based on the waterfall structure while slowing down the flow speed of the medium.

[0052] At the third position, all the collecting wheel structures 4 are moved into the collecting wheel accommodating chamber 3. The third position is a standby position of the collecting wheel body 41, which can realize the free flow of the medium.
