Description

Technical Field

[0001] This invention discloses a self-powered sensing device for river ecological monitoring that utilizes river energy and wind energy, belonging to the field of ecological monitoring technology. Background Technology

[0002] Rivers are among the most important water resources on Earth, and human societies rely on them for water supply, irrigation of farmland, power generation, and industrial use. Monitoring changes in the river's ecological environment not only ensures the sustainable use of water resources but also helps prevent disasters such as floods and mudslides. However, current river ecological environment monitoring methods are too simplistic, inefficient, and costly, lacking a low-cost, high-efficiency integrated self-powered sensor that utilizes the Internet of Things (IoT) for river ecological environment monitoring.

[0003] TENG sensors, with their excellent characteristics such as high-efficiency energy harvesting, excellent flexibility and adaptability, environmental sustainability, low cost, and easy integration, can be used in relatively harsh conditions and have broad prospects in fields such as river sensing systems, ecological environment monitoring, and natural disaster early warning.

[0004] The earliest invented TENG (Temperature Engagement Module) operated in a vertical contact-separation mode. Initially, the two electrodes were electrically neutral. Under external force, the electrodes came into contact. Because the two electrode materials had different attraction for electrons, electrons transferred between the electrodes, generating a voltage between the upper and lower friction layers, thus transferring mechanical energy to electrical energy. The horizontal sliding TENG operates on the same principle as the vertical contact-separation TENG, except that the relative motion of the two electrodes changes from perpendicular to the friction layer to parallel to it. The single-electrode TENG differs from the above two in that one electrode does not move but is fixed to the ground. When the relative position between the electrodes changes, the fixed surface exchanges electrons with the ground. The independent-layer type is an extension of the aforementioned TENGs. After friction with the two electrodes, the friction layer carries a certain charge. When it moves relative to the two electrodes, a periodic alternating current is generated between them.

[0005] Currently, most TENG sensors are self-powered and cannot collect enough energy from the environment for data transmission. River monitoring is generally carried out by satellites or meteorological bureaus, which is costly, inefficient, and provides overly simplistic monitoring data. Summary of the Invention

[0006] The purpose of this invention is to solve the problems that most existing TENG sensors are self-powered and cannot collect enough energy from the environment for data transmission. River monitoring is generally carried out by satellite or meteorological bureaus, which is costly, inefficient and provides overly simplistic monitoring data. This invention proposes a self-powered sensing device for river ecological monitoring that utilizes river energy and wind energy.

[0007] The problem to be solved by this invention is achieved by the following technical solution:

[0010] Preferably, the water level sensing assembly includes a lifting frame with a foam ring fixed at its lower end. At least three sliders are evenly arranged on the inner side of the lifting frame. The outer side of the H-shaped cylindrical base is provided with a slide rail that can slide along the at least three sliders. Between two adjacent slide rails, a plurality of water level sensing copper sheets with the same width and decreasing length are arranged at equal intervals from top to bottom. The outer side of the plurality of water level sensing copper sheets is covered with a water level sensing arc-shaped nylon sheet. A triangular bracket is provided on the inner side of the lifting frame at a corresponding position between two adjacent slide rails. An arc-shaped water level sensing FEP film is provided on the inner side of the triangular bracket. When the arc-shaped water level sensing FEP film slides along the sliders via the slide rails, it can move sequentially to correspond to the positions of the plurality of water level sensing copper sheets.

[0011] Preferably, the water level sensing assembly further includes a protective sleeve disposed on the top of the triangular bracket inside the lifting frame. The inner side of the protective sleeve can slide along the arc-shaped nylon sheet of the water level sensing and is limited by a positioning rod uniformly fixed inside the lifting frame.

[0012] Preferably, the flow rate sensing assembly includes a bearing post fixed at the top of the connecting frame at the other end. The side of the bearing post is rotatably mounted on a blade shell with blades evenly arranged on its outer side via a waterproof bearing. An annular positioning platform is fixed at the end of the bearing post away from the connecting frame. Multiple flow rate sensing copper sheets are evenly arranged on the outer side of the annular positioning platform. Each of the multiple flow rate sensing copper sheets is covered with a flow rate sensing arc-shaped nylon sheet. Multiple flow rate sensing FEP films are arranged at corresponding positions on the inner side of the blade shell with the multiple flow rate sensing copper sheets. The tangents of the multiple flow rate sensing FEP films are perpendicular to the tangents on the inner side of the blade shell. The annular positioning platform, the multiple flow rate sensing arc-shaped nylon sheets, the multiple flow rate sensing FEP films, and the multiple flow rate sensing copper sheets are enclosed in the blade shell by a rotating disk.

[0013] Preferably, the electromagnetic power generation assembly includes a planetary gear support frame rotatably mounted on a rotating disk via an electromagnetic power generation waterproof bearing and positioned by a lower end cover.

Multiple planetary gears are evenly rotatably mounted on the planetary gear support frame ring platform via a support shaft. Each of the multiple planetary gears engages with an internal gear ring fixed to the inner side of the blade housing. The planetary gear support frame in the middle of the planetary gear support frame ring platform is rotatably connected to one end of the sun gear stepped shaft via a deep groove ball bearing. The middle of the sun gear stepped shaft has a sun gear that engages with the multiple planetary gears. An electromagnetic power generation coil support disk is rotatably mounted on the sun gear stepped shaft via a support bearing. Multiple lower electromagnetic power generation copper coils are evenly arranged in a ring on the electromagnetic power generation coil support disk. Multiple upper electromagnetic power generation copper coils are evenly arranged in a ring at the bottom of the ring positioning platform. An electromagnetic power generation magnet support disk is fixed to the other end of the sun gear stepped shaft. Multiple electromagnetic power generation magnet discs are evenly embedded in a ring on the electromagnetic power generation magnet support disk.

[0014] The advantages of this invention compared to existing technologies are as follows:

[0015] This invention fills the gap in current single-energy collection by rationally designing the simultaneous collection of wind and river energy, and improves the collection efficiency of environmental energy. The water level sensing assembly and flow velocity sensing assembly are used for sensing, the wind power generation assembly can be used for sensing and power generation respectively, and the electromagnetic power generation assembly is used for power generation.

Detailed Implementation

[0030] The following is based on the appendix Figure 1-12 Further explanation of the present invention:

[0031] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0033] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] like Figure 1-3 As shown, the first embodiment of the present invention provides a self-powered sensing device for river ecological monitoring that utilizes river energy and wind energy, based on the prior art. It includes a wind power generation assembly 100, a water level sensing assembly 200 that is slidably mounted on the outside of the wind power generation assembly 100, and the bottom of the wind power generation assembly 100 is connected to the flow velocity sensing assembly 300 through a connecting frame 500. An electromagnetic power generation assembly 400 is provided inside the flow velocity sensing assembly 300.

[0035] like Figure 4 As shown, the wind power generation assembly 100 includes wind power generation copper coils 107 evenly arranged in a ring on the upper part of the central ring of an H-shaped cylindrical base 108. The top of the H-shaped cylindrical base 108 is closed by a base cover 104. A wind scoop support shaft 102 is rotatably inserted through the center of the base cover 104 via a wind power generation deep groove ball bearing 103. A wind scoop support shaft 102 is bolted to one end inside the H-shaped cylindrical base 108 to a wind power generation magnet support plate 105. A disc magnet 106 corresponding to the wind power generation copper coils 107 is evenly arranged in a ring on the inner side of the wind power generation magnet support plate 105. A wind scoop frame 109 is fixed to one end of the wind scoop support shaft 102 outside the H-shaped cylindrical base 108. Multiple connecting ends on the side of the wind scoop frame 109 are connected to the wind scoop 101 respectively. The lower part of the central ring of the H-shaped cylindrical base 108 is connected to one end of a connecting frame 500. When the wind-driven support shaft 102 of the wind-driven support shaft 102 rotates due to wind power, the disc magnet 106 on the wind power generation magnet support plate 105 moves relative to the stationary wind power generation copper coil 107, cutting the magnetic field lines to generate electricity. It can also monitor the wind speed, and the measured voltage signal is sent to the host computer through the wireless communication module.

[0036] like Figure 5-8 As shown, the water level sensing assembly 200 includes a lifting frame 203 with a foam ring 207 fixed at its lower end. At least three sliders 204 are evenly arranged on the inner side of the lifting frame 203. In this embodiment, there are four sliders. The outer side of the H-shaped cylindrical base 108 is provided with a slide rail 201 that can slide along at least three sliders 204. Between two adjacent slide rails 201, multiple water level sensing copper sheets 202 with the same width and decreasing length are arranged at equal intervals from top to bottom. Each layer of copper sheets is spaced apart and the width increases by the same amount with each layer, so that the voltage amplitude changes to a certain extent.

[0037] Multiple water level sensing copper plates 202 are covered with curved water level sensing nylon sheets 205. A triangular bracket 210 is provided on the inner side of the lifting frame 203 at corresponding positions between two adjacent slide rails 201. A curved water level sensing FEP film 206 is provided inside the triangular bracket 210. The curved water level sensing FEP film 206 can move sequentially to correspond to the positions of the multiple water level sensing copper plates 202 as it slides along the slider 204 via the slide rail 201. Because the contact area of ​​the two electrode materials differs, the amplitude of the voltage signal obtained also differs. Therefore, by changing the contact area of ​​the two electrode materials, the water level can be monitored. The measured voltage signal is transmitted to the host computer via a wireless communication module.

[0038] The water level sensing assembly 200 also includes a protective sleeve 209 installed on the top of the triangular bracket 210 inside the lifting frame 203. The inner side of the protective sleeve 209 can slide along the water level sensing arc-shaped nylon sheet 205 and is limited by the positioning rod 208 uniformly fixed inside the lifting frame 203.

[0039] like Figure 9 As shown, the flow velocity sensing assembly 100 includes a bearing column 303 fixed to the other end of the connecting frame 500 by bolts at the top. A blade housing 307 with blades evenly arranged on the outside is rotatably mounted on the side of the bearing column 303 via a waterproof bearing 302. An annular positioning platform 304 is fixed to the end of the bearing column 303 away from the connecting frame 500. Multiple flow velocity sensing copper sheets 306 are evenly arranged on the outside of the annular positioning platform 304. Each of the multiple flow velocity sensing copper sheets 306 is covered with a flow velocity sensing arc-shaped nylon sheet 301. Multiple flow velocity sensing FEP films 305 are arranged at corresponding positions on the multiple flow velocity sensing copper sheets 306 on the inside of the blade housing 307. Similarly, the amplitude of the voltage signal obtained is also different when the contact area of ​​the two electrode materials is different. Therefore, the river can be monitored by changing the contact area of ​​the two electrode materials. The measured voltage signal is sent to the host computer through a wireless communication module.

[0040] The tangents of multiple flow rate sensing FEP films 305 are perpendicular to the tangents on the inner side of the blade housing 307. The annular positioning stage 304, multiple flow rate sensing arc-shaped nylon sheets 301, multiple flow rate sensing FEP films 305, and multiple flow rate sensing copper sheets 306 are enclosed in the blade housing 307 by a rotating disk 308.

[0041] like Figure 10-12As shown, the electromagnetic power generation assembly 400 includes a planetary gear support frame 402, one end of which is rotatably mounted on a rotating disk 308 via an electromagnetic power generation waterproof bearing 401 and positioned by a lower end cover 413. The other end of the planetary gear support frame 402 has a planetary gear support frame ring platform. Multiple planetary gears 411 are evenly rotatably arranged on the planetary gear support frame ring platform via a support shaft. Each planetary gear 411 engages with an internal gear ring 412 fixed to the inner side of the blade housing 307. The planetary gear support frame 402 in the middle of the planetary gear support frame ring platform is rotatably connected to one end of the sun gear stepped shaft 408 via a deep groove ball bearing 410. A sun gear, which engages with multiple planetary gears 411, is located in the middle of the stepped shaft 408 of the sun gear. An electromagnetic power generation coil support disk 407 is rotatably mounted on the stepped shaft 408 via a support bearing 409. Multiple lower electromagnetic power generation copper coils 406 are evenly arranged in a ring on the electromagnetic power generation coil support disk 407. Multiple upper electromagnetic power generation copper coils 403 are evenly arranged in a ring at the bottom of the annular positioning platform 304. An electromagnetic power generation magnet support disk 405 is fixed to the other end of the stepped shaft 408. Multiple electromagnetic power generation magnet discs 404 are evenly embedded in a ring on the electromagnetic power generation magnet support disk 405, forming two layers of coils. As the blades rotate, carrying the blade housing 307, the multiple electromagnetic power generation magnet discs 404 evenly embedded in a ring on the electromagnetic power generation magnet support disk 405, in conjunction with the upper and lower layers of electromagnetic power generation copper coils, cut magnetic field lines to generate electrical energy. The wireless communication module is powered by the electrical energy collected from the electromagnetic power generation assembly and the wind power generation assembly.

[0042] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. It can be applied to various fields suitable for the present invention. Other modifications can be readily made by those skilled in the art. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and examples shown and described herein.
