Description

Technical Field

[0001] The present invention relates to the technical field of ocean monitoring, and in particular to a self-powered monitoring device for flexible and adaptive wave energy collection. Background Art

[0002] With the rapid growth of IoT technology and the demand for intelligent ocean monitoring, the role of ocean distributed sensor networks in monitoring ocean environmental parameters is becoming increasingly important. These sensors can monitor ocean temperature, salinity, wave height, current speed and other information in real time, thus providing data support for marine ecological protection, climate change research and marine resource development.

[0003] However, the power supply of marine distributed sensors mainly relies on lithium batteries, but lithium batteries have many defects. For example, lithium batteries have limited capacity, short battery life, environmental pollution, and difficulty in replacement in the marine environment. These defects limit the long-term stable deployment of marine distributed sensor networks and affect the rapid development of marine ecological protection, climate change research, and marine resource development. Summary of the invention

[0004] The present invention provides a flexible and adaptive wave energy collection self-powered monitoring device, which is used to reduce the dependence of the monitoring device on traditional lithium batteries, so that the monitoring device has a lasting and stable green energy supply.

[0005] The embodiment of the present invention provides a self-powered monitoring device for flexible adaptive wave energy collection, the self-powered monitoring device comprising a housing, a friction nano-power generation device, a power consumption device and a power management device;

[0006] The shell has a first deformation portion, and the first deformation portion has a recessed state and a rebound state; during the movement of waves, the first deformation portion can switch between the recessed state and the rebound state;

[0007] The friction nano power generation device is located in the housing, and includes a first component, a second component, a first friction power generation module, and a second friction power generation module; the first component is connected to the first deformation part, and when the first deformation part switches between the recessed state and the rebound state, the first component and the second component have relative movement;

[0008] The first friction power generation module is located in the first component, and the second friction power generation module is located in the second component. The first friction power generation module and the second friction power generation module are used for friction power generation during the relative movement of the first component and the second component;

[0009] The power management device is connected to the power-consuming device, and is used to store the electric energy generated by the friction nano-power generation device and supply power to the power-consuming device.

[0010] When the above self-powered monitoring device is used in a specific application, a portion of the wave energy can be converted into relative movement between the first component and the second component through the reciprocating concave-rebound motion of the first deformation part, thereby promoting the friction power generation of the first friction power generation module and the first friction power generation module. The friction nano-power generation device can permanently use the wave energy in the ocean to generate electricity, thereby ensuring the electricity demand of the electrical device, so that the self-powered monitoring device has a longer endurance and can work underwater for a long time. In addition, due to the change in the power supply method, the above self-powered monitoring device is more environmentally friendly, thereby reducing the harm to the environment.

[0011] When the first deformation portion is specifically set, in a possible technical solution, when the first deformation portion is in the rebound state, a surface of the first deformation portion facing away from the first component is an arc surface, and the arc surface bulges in a direction away from the first component.

[0012] The first deformation part has a larger surface area, thus having a larger force-bearing surface, and is more likely to be deformed in a concave state during the movement of waves. In addition, when the first deformation part switches between the concave state and the rebound state, the displacement of the vertex of the first deformation part is large, so that the first component can be displaced relatively to the second component, thereby correspondingly increasing the power generation of the friction nano power generation device.

[0013] In a possible technical solution, the first deformation part includes an elastic material. The elastic material makes the first deformation part relatively flexible, so that the first deformation part is relatively easy to be recessed into the inner cavity of the shell under the action of water pressure. After the first deformation part is recessed into the inner cavity of the shell, the first deformation part will generate an elastic restoring force, and the first deformation part can rebound under the action of the elastic restoring force.

[0014] In another possible technical solution, a first gas is encapsulated in the shell. After the first deformation portion is recessed into the inner cavity of the shell, the internal space of the shell is reduced, so that the first gas is compressed. When the pressure outside the shell is reduced, the first gas can make the first deformation portion rebound by doing work through expansion.

[0015] In a possible technical solution, the housing further comprises a connecting portion, the connecting portion is located on an outer peripheral side of the first deformation portion, and the connecting portion is connected to an edge of the first deformation portion;

[0016] The thickness of the first deformation portion is smaller than the thickness of the connection portion.

[0017] In the above technical solution, since the first deformation portion is relatively thin, the first deformation portion is relatively easy to deform.

[0018] Regarding the relative movement form between the first component and the second component, in a possible technical solution, a transmission assembly is arranged between the first component and the first deformation part, and during the process of switching of the first deformation part between the recessed state and the rebound state, the transmission assembly is used to drive the first component to rotate relative to the second component.

[0019] When the transmission assembly and the first deformation part are specifically connected, in a possible technical solution, the housing further has a convex bulge, and the convex bulge has a hollow cavity; wherein:

[0020] A portion of the transmission assembly is accommodated in the convex hull and connected to the inner wall of the convex hull;

[0021] The first deformation portion is located at the outer peripheral side of the convex hull, and the first deformation portion is connected to the edge of the convex hull.

[0022] In the above technical solution, the transmission assembly is indirectly connected to the first deformation part through the convex bulge. The convex bulge reduces the space of the main cavity of the housing occupied by the transmission assembly and improves the fixing effect of the transmission assembly.

[0023] When the transmission assembly is specifically arranged, in a possible technical solution, the transmission assembly includes a first transmission shaft and a sliding sleeve arranged at the end of the first transmission shaft; wherein:

[0024] The inner wall of the sliding sleeve is provided with a spiral groove, and the outer wall of the first transmission shaft is provided with a limit block, and the limit block is located in the spiral groove;

[0025] The sliding sleeve is connected to the first deformation portion, and the first transmission shaft is connected to the first component.

[0026] In the above technical solution, the movement of the waves can be transmitted to the first component through the first deformation portion, the sliding sleeve, and the first transmission shaft, so that the first component rotates relative to the second component.

[0027] In another possible technical solution, the transmission assembly includes a lead screw and a nut seat provided at an end of the lead screw; the lead screw is connected to the first component, and the nut seat is connected to the first deformation portion.

[0028] In the above technical solution, the movement of the waves can be transmitted to the first component through the first deformation portion, the nut seat, and the lead screw, so that the first component rotates relative to the second component.

[0029] In another possible technical solution, the transmission assembly includes a rack, a gear and a second transmission shaft; wherein:

[0030] The end of the rack is connected to the first deformation portion, and the rack is meshed with the gear;

[0031] The second transmission shaft passes through the center of the gear and the center of the first component, and the second transmission shaft is connected to the gear and the first component respectively.

[0032] In the above technical solution, the movement of the waves can be transmitted to the first component through the first deformation part, the rack, the gear, and the second transmission shaft, so that the first component rotates relative to the second component.

[0033] When specifically setting the structures of the first component and the second component, in a possible technical solution, both the first component and the second component are annular structures, and the second component is sleeved on the outside of the first component.

[0034] In the above technical solution, the first component and the second component have a larger surface area, thereby providing a larger space for the arrangement of the friction nano power generation device.

[0035] Optionally, the shell is a flexible shell, the second component is supported on an inner wall of the shell, and the second component avoids the first deformation portion.

[0036] When the friction nano power generation device is specifically arranged, in a possible technical solution, the first friction power generation module includes a friction part, and the friction part has insulation; the second friction power generation module includes a first electrode part and a second electrode part, the first electrode part and the second electrode part are alternately arranged along the circumferential direction, and the first electrode part and the second electrode part are respectively connected to the power management device;

[0037] During the relative rotation of the first member and the second member, the friction portion contacts the first electrode portion and the second electrode portion alternately.

[0038] In a possible technical solution, during the switching of the first deformation portion between the recessed state and the rebounded state, the first component is used to perform linear motion relative to the second component along a first direction. The first component can perform linear motion along with the recessed-rebounded motion of the first deformation portion, thereby simplifying the structure and reducing the space occupied by the friction nano power generation device.

[0039] When specifically connecting the first component and the first deformation part, the first component can be directly connected to the first deformation part, or the first component can be indirectly connected to the first deformation part through an intermediate component. In a possible technical solution, the shell also has a convex hull, and the convex hull has a hollow cavity; a part of the first component is accommodated in the convex hull and connected to the inner wall of the convex hull; the first deformation part is located on the outer peripheral side of the convex hull, and the first deformation part is connected to the edge of the convex hull. In this way, the first component is indirectly connected to the first deformation part through the convex hull.

[0040] In the above technical solution, the first component is indirectly connected to the first deformation portion through the convex hull. At the same time, since the inner wall of the convex hull has a large surface area, the fixing effect of the first component can be increased after the first component is connected to the inner wall of the convex hull.

[0041] In a possible technical solution, the shell further includes a second deformation portion, and the second deformation portion and the first deformation portion are located at two opposite ends of the shell along the first direction;

[0042] The second deformation portion also has a recessed state and a rebound state, and during the movement of waves, the second deformation portion can also switch between the recessed state and the rebound state;

[0043] The second deformation portion is connected to the second component.

[0044] In an application scenario of the above technical solution, the first deformation part and the second deformation part can be recessed and rebounded simultaneously, so that the first component and the second component can slide in opposite directions, thereby increasing the relative displacement between the first component and the second component and improving power generation.

[0045] In a possible technical solution, a plurality of the friction nano power generation devices are arranged in the shell. BRIEF DESCRIPTION OF THE DRAWINGS

[0082] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0083] In the description of the present application, unless otherwise expressly specified and limited, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance; the term "plurality" refers to two or more; the term "and / or" includes any and all combinations of one or more associated listed items. In particular, reference to "the / the" object or "an" object is also intended to indicate one of a possible plurality of such objects.

[0084] Unless otherwise specified or explained, the terms "connection", "fixed", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, an integral connection, an electrical connection, or a signal connection; "connection" can be a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0085] The present application provides a self-powered monitoring device for flexible and adaptive wave energy collection. For the convenience of description, the "self-powered monitoring device for flexible and adaptive wave energy collection" will be referred to as the "self-powered monitoring device" below. First, the application scenarios of the self-powered monitoring device are introduced. The self-powered monitoring device can be used in marine environments to monitor the temperature, salinity, wave height, flow rate and other information in the ocean in real time, and provide data support for marine ecological protection, climate change research and marine resource development. Of course, the self-powered monitoring device can also be used in water environments such as rivers, lakes and other water environments to monitor the parameters in the above water environments.

[0086] The self-powered monitoring equipment can include a variety of sensors to detect the temperature, salinity, speed and other information of the seawater. The above sensors can be powered by lithium batteries during operation, but considering that the self-powered monitoring equipment needs to work underwater for a long time, the use of lithium batteries for power supply has many defects. For example, the capacity of lithium batteries is limited, so the battery life of lithium batteries is short. Once the lithium battery is low on power, the marine distributed sensors need to be salvaged from underwater, then replaced, and finally installed in the underwater environment, which makes it difficult to replace the lithium battery. In addition, during use, chemical substances such as electrolytes in lithium batteries may leak, causing pollution to the ocean. The above defects limit the long-term and stable deployment of self-powered monitoring equipment underwater, affecting the rapid development of marine ecological protection, climate change research, and marine resource development.

[0087] The self-powered monitoring device provided in this application is intended to reduce dependence on traditional lithium batteries, so that the self-powered monitoring device has a long-lasting and stable green energy supply.

[0088] Figure 1 A schematic diagram of a self-powered monitoring device provided by an embodiment of the present invention is shown in FIG. Figure 1 As shown, in one embodiment, the self-powered monitoring device includes a housing 10, a friction nano-power generation device 20, a power management device 30, and an electrical device 40. The housing 10 has a sealed chamber, which can provide a storage space for the friction nano-power generation device 20, the power management device 30, and the electrical device 40, and can reduce the risk of the above devices getting wet. In a specific embodiment, the housing 10 includes a first housing 11 and a second housing 12, and the first housing 11 and the second housing 12 are buckled together to form the above-mentioned sealed chamber.

[0089] The friction nano power generation device 20 is used to generate electricity using wave energy. The number of the friction nano power generation device 20 can be one, or, in order to increase the power generation, the number of the friction nano power generation device 20 can also be two, three or other numbers not less than two, which are not listed one by one in this application.

[0090] The power management device 30 is connected to the friction nano power generation device 20, and is used to rectify and filter the current. The power management device 30 is also connected to the power consumption device 40, and can supply power to the power consumption device 40 so that the power consumption device 40 can work normally. Optionally, the power consumption device 40 can be a monitoring device such as a temperature sensor, a flow rate sensor, a salinity sensor, etc. Alternatively, the power consumption device 40 can also be an auxiliary device such as a lighting lamp.

[0091] In the marine environment, wave energy is a widely distributed and renewable green energy source. The friction nano power generation device 20 can permanently utilize wave energy to generate electricity, thereby ensuring the power demand of the power-consuming device 40, so that the self-powered monitoring device has a longer endurance and can work underwater for a long time. In addition, due to the change in the power supply method, the above self-powered monitoring device is more environmentally friendly, thereby reducing the harm to the environment.

[0092] The self-powered monitoring device may include one power-consuming device 40 or may include multiple power-consuming devices 40. In the embodiment where the self-powered monitoring device includes multiple power-consuming devices 40, the electric energy generated by the friction nano-power generation device 20 may be used to power all the power-consuming devices 40, or the electric energy generated by the friction nano-power generation device 20 may be used to power only a part of the power-consuming devices 40, while the other power-consuming devices 40 are powered by lithium batteries.

[0093] In order to generate electricity using wave energy, the present application has made mutually compatible structural designs for the shell 10 and the friction nano power generation device 20, which are respectively described below.

[0094] Figure 2 A schematic diagram of a state of a housing provided by an embodiment of the present invention, Figure 3 Another state schematic diagram of the housing provided by the embodiment of the present invention is as follows: Figure 2 and Figure 3 As shown, in some embodiments, the shell 10 has a first deformation portion 101, and the first deformation portion 101 has a concave state and a rebound state. When the first deformation portion 101 is in the concave state, the first deformation portion 101 forms a pit on the surface of the shell 10. When the first deformation portion 101 is in the rebound state, the shell 10 returns to its original shape. In the marine environment, with the periodic movement of waves, the first deformation portion 101 of the shell 10 can repeatedly switch between the above-mentioned concave state and the rebound state.

[0095] Specifically, in an underwater environment, when the first deformation part 101 is in a rebound state, the first deformation part 101 can withstand a certain pressure, so that the shell 10 can maintain its initial shape. The movement of the waves will cause changes in the pressure outside the shell 10. When the pressure outside the shell 10 increases, the first deformation part 101 can be recessed into the inner cavity of the shell 10 under the action of the external pressure, so that a pit is generated on the surface of the shell 10, and the first deformation part 101 switches from the rebound state to the recessed state. In this process, a part of the wave energy can be converted into the mechanical energy of the first deformation part 101. When the pressure outside the shell 10 decreases, the first deformation part 101 can rebound, so that the shell 10 returns to its initial shape, and the first deformation part 101 switches from the recessed state to the rebound state.

[0096] When the first deformation part 101 is specifically set, the first deformation part 101 includes an elastic material. The elastic material makes the first deformation part 101 relatively flexible, so that the first deformation part 101 is relatively easy to be recessed into the inner cavity of the shell 10 under the action of water pressure. After the first deformation part 101 is recessed into the inner cavity of the shell 10, the first deformation part 101 will generate an elastic restoring force. When the pressure outside the shell 10 is reduced, the first deformation part 101 can rebound under the action of the elastic restoring force. Optionally, the elastic material can be silicone, rubber or polyurethane.

[0097] In one embodiment, a first gas is encapsulated in the shell 10. After the first deformation portion 101 is recessed into the inner cavity of the shell 10, the internal space of the shell 10 is reduced, so that the first gas is compressed. When the pressure outside the shell 10 is reduced, the first gas expands and does work to make the first deformation portion 101 rebound. In other words, the first deformation portion 101 can rebound under the expansion of the first gas. Optionally, the first gas can be air, nitrogen, carbon dioxide or other compressible gases, which are not listed one by one in this application.

[0098] In specific implementation, the first deformation part 101 can be made of elastic material so that the first deformation part 101 can rebound under the action of elastic restoring force. At the same time, the first gas can be encapsulated in the shell 10 so that the first deformation part 101 can rebound through the expansion work of the first gas.

[0099] Figure 4 A schematic diagram of the internal structure of a self-powered monitoring device provided by an embodiment of the present invention, such as Figure 4 As shown, in one embodiment, the friction nano power generation device 20 includes a first component 21, a second component 22, a first friction power generation module 23 and a second friction power generation module 24. Among them, the first component 21 is connected to the first deformation part 101. In the process of the first deformation part 101 being recessed and rebounding into the inner cavity of the shell 10, the first component 21 will move following the movement of the first deformation part 101. And, in this process, the first component 21 and the second component 22 have relative movement. The first friction power generation module 23 is located in the first component 21, and the second friction power generation module 24 is located in the second component 22. In the process of relative movement between the first component 21 and the second component 22, the first friction power generation module 23 and the second friction power generation module 24 generate friction power, thereby converting mechanical energy into electrical energy.

[0100] When the above self-powered monitoring device is used in a specific application, a part of the wave energy can be converted into the relative movement between the first component 21 and the second component 22 through the reciprocating concave-rebound motion of the first deformation part 101, thereby promoting the friction power generation of the first friction power generation module 23 and the second friction power generation module 24. The first deformation part 101 has the ability to quickly perceive and adjust the change of water pressure, and its shape can be dynamically adjusted with the change of water pressure. For example, when the water pressure is high, the first deformation part 101 is more concave to the inside of the shell 10, and the relative displacement between the first component 21 and the second component 22 is large. On the contrary, when the water pressure is low, the first deformation part 101 is less concave to the inside of the shell 10, and the relative displacement between the first component 21 and the second component 22 is also small. Therefore, the first deformation part 101 has a strong adaptive characteristic. This adaptive characteristic enables the first deformation part 101 to drive the first component 21 and the second component 22 to produce relative movement in different water pressure environments, thereby promoting the friction power generation of the first friction power generation module 23 and the second friction power generation module 24.

[0101] The self-powered monitoring device can capture wave energy in a variety of water environments through the first deformation portion 101, and has a wide range of applicability. For example, the self-powered monitoring device can be installed in water environments of different depths and different flow rates as needed. During use, the first deformation portion 101 can continuously capture wave energy, so that the friction nano-power generation device 20 can permanently use wave energy to generate electricity, thereby providing a guarantee for the power consumption of the electrical device.

[0102] Please continue to refer to Figure 4 In one embodiment, when the first deformation portion 101 is in a rebound state, the surface of the first deformation portion 101 on one side facing away from the first component 21 is an arc surface, and the arc surface bulges in the direction away from the first component 21. The above-mentioned first deformation portion 101 has a large surface area, and thus has a large force-bearing surface, and is more likely to be concavely deformed during the movement of waves. In addition, when the first deformation portion 101 switches between the concave state and the rebound state, the displacement of the vertex of the first deformation portion 101 is large, so that the first component 21 can produce a large displacement relative to the second component 22, thereby correspondingly increasing the power generation of the first friction power generation module 23 and the second friction power generation module 24.

[0103] In other embodiments, when the first deformation portion 101 is in the rebound state, the surface of the first deformation portion 101 facing away from the first component 21 may also be planar.

[0104] The first component 21 and the second component 22 include multiple relative motion forms. In one embodiment, the first component 21 and the second component 22 can rotate relative to each other. In another embodiment, the first component 21 and the second component 22 can move relative to each other along a straight line. Among them, the first component 21 and the second component 22 can be relatively close to or relatively far away from each other along a straight line. Alternatively, the first component 21 and the second component 22 can also slide relative to each other along a straight line. In the above embodiments, the first component 21 is a moving component, and the second component 22 can be a moving component or a fixed component.

[0105] The first friction power generation module 23 and the second friction power generation module 24 include a plurality of working modes according to the different forms of relative movement between the first component 21 and the second component 22. When the first component 21 and the second component 22 rotate relative to each other, the first friction power generation module 23 and the second friction power generation module 24 will slide relative to each other and generate electricity during the relative sliding process. When the first component 21 and the second component 22 are relatively close to or relatively far away from each other along a straight line, the first friction power generation module 23 and the second friction power generation module 24 will vertically contact-separate and generate electricity during repeated vertical contact-separation. When the first component 21 and the second component 22 slide relative to each other along a straight line, the first friction power generation module 23 and the second friction power generation module 24 will also slide relative to each other and generate electricity during the relative sliding process.

[0106] Figure 5 A schematic diagram of the internal structure of a self-powered monitoring device provided by an embodiment of the present invention, such as Figure 5 As shown, in one embodiment, a transmission assembly 25 is provided between the first component 21 and the first deformation portion 101, and the transmission assembly 25 is used to drive the first component 21 to rotate relative to the second component 22 during the process of the first deformation portion 101 being recessed and rebounded into the inner cavity of the housing 10. In other words, the transmission assembly 25 can convert the repeated recessing and rebounding of the first deformation portion 101 into the rotational motion of the first component 21.

[0107] When the transmission assembly 25 is specifically configured, the transmission assembly 25 includes a variety of structural forms. Figure 6 A schematic diagram of a structure of a transmission assembly provided in an embodiment of the present invention, such as Figure 6 As shown, in one embodiment, the transmission assembly 25 includes a first transmission shaft 251 and a sleeve 252 disposed at the end of the first transmission shaft 251. The inner wall of the sleeve 252 has a spiral groove, and the outer wall of the first transmission shaft 251 has a stopper 2511, and the stopper 2511 is located in the spiral groove. The sleeve 252 is connected to the first deformation portion 101, and when the first deformation portion 101 is recessed or rebounded toward the inner cavity of the housing 10, the sleeve 252 will slide along the first transmission shaft 251. In this process, the stopper 2511 slides along the spiral groove, thereby causing the first transmission shaft 251 to rotate.

[0108] In a specific embodiment, the inner wall of the sleeve 252 is provided with a plurality of spiral grooves. Correspondingly, the outer wall of the first transmission shaft 251 is provided with a plurality of limit blocks 2511, which are arranged circumferentially, and each limit block 2511 is located in a spiral groove. In the above embodiment, by providing a plurality of spiral grooves on the inner wall of the sleeve 252 and providing a corresponding number of limit blocks 2511 circumferentially on the outer wall of the first transmission shaft 251, the force on the first transmission shaft 251 can be made more uniform, so that the first transmission shaft 251 can rotate stably. When installing the first transmission shaft 251, a base is provided inside the housing 10, and the base is fixedly connected to the housing 10, and one end of the first transmission shaft 251 away from the sleeve 252 is inserted into the base and slidably connected to the base.

[0109] The first component 21 is connected to the first transmission shaft 251, and the first component 21 rotates when the first transmission shaft 251 rotates. In this way, the motion of the wave is transmitted to the first component 21 through the first deformation part 101, the sleeve 252, and the first transmission shaft 251, so that the first component 21 rotates relative to the second component 22.

[0110] When the first component 21 and the second component 22 are specifically arranged, as shown in FIG. Figure 5As shown, in one embodiment, the first component 21 can be an annular structure. The first component 21 is arranged around the circumference of the first transmission shaft 251, and the first component 21 can be connected to the first transmission shaft 251 through a disc-shaped structure. Correspondingly, the second component 22 can also be an annular structure, and the second component 22 is sleeved on the outside of the first component 21. The first component 21 and the second component 22 have a large surface area, thereby providing a large layout space for the first friction power generation module 23 and the second friction power generation module 24.

[0111] In other embodiments, the first component 21 may also be a disc-shaped structure. The center of the first component 21 is connected to the first transmission shaft 251, and the first component 21 may rotate under the drive of the first transmission shaft 251. Correspondingly, the second component 22 may also be a disc-shaped structure, and the second component 22 and the first component 21 are arranged opposite to each other.

[0112] Figure 7 Another structural schematic diagram of a transmission assembly provided by an embodiment of the present invention is as follows: Figure 7 As shown, in another embodiment, the transmission assembly 25 includes a rack 253, a gear 254 and a second transmission shaft 255. The end of the rack 253 is connected to the first deformation part 101, and the rack 253 will move accordingly with the deformation of the first deformation part 101 during the process of the first deformation part 101 being recessed and rebounding into the inner cavity of the housing 10. The gear 254 is meshed with the rack 253, and the gear 254 can rotate as the rack 253 moves. The second transmission shaft 255 passes through the center of the gear 254 and the center of the first component 21, and the second transmission shaft 255 is connected to the gear 254 and the first component 21 respectively. During the rotation of the gear 254, the second transmission shaft 255 will rotate synchronously, and the first component 21 can rotate with the rotation of the second transmission shaft 255. In this way, the movement of the wave is transmitted to the first component 21 through the first deformation part 101, the rack 253, the gear 254, and the second transmission shaft 255, so that the first component 21 rotates relative to the second component 22.

[0113] When the first component 21 and the second component 22 are specifically arranged, the first component 21 and the second component 22 may be an annular structure or a disc-shaped structure adapted to each other. Figure 5 The description in the corresponding embodiment will not be repeated here.

[0114] It is worth pointing out that in the above embodiment, the number of the first components 21 can be multiple, and the multiple first components 21 are arranged at intervals along the extension direction of the second transmission shaft 255. Each first component 21 can correspond to a second component 22, and a first friction power generation module 23 and a second friction power generation module 24 can be provided between each pair of the first component 21 and the second component 22.

[0115] Figure 8 Another structural schematic diagram of a transmission assembly provided by an embodiment of the present invention is as follows: Figure 8 As shown, in another embodiment, the transmission assembly 25 includes a lead screw 256 and a nut seat 257 disposed on the lead screw 256, the lead screw 256 is connected to the first component 21, and the nut seat 257 is connected to the first deformation portion 101. In the process of the first deformation portion 101 being recessed and rebounding into the inner cavity of the shell 10, the nut seat 257 can move and drive the lead screw 256 to rotate. Since the first component 21 is connected to the lead screw 256, the first component 21 can rotate with the rotation of the lead screw 256. In this way, the movement of the wave is transmitted to the first component 21 through the first deformation portion 101, the nut seat 257, and the lead screw 256, so that the first component 21 rotates relative to the second component 22.

[0116] When the first component 21 and the second component 22 are specifically arranged, the first component 21 and the second component 22 may be an annular structure or a disc-shaped structure adapted to each other. Figure 5 The description in the corresponding embodiment will not be repeated here.

[0117] The above embodiments introduce several specific structural forms in which the transmission component 25 converts the depression-rebound motion of the first deformation portion 101 into the rotational motion of the first component 21. Of course, the transmission component 25 can also achieve the above effects through other structural forms, which are not listed one by one in this application.

[0118] When the transmission assembly 25 and the first deformation part 101 are specifically connected, the transmission assembly 25 can be directly connected to the first deformation part 101. Alternatively, the transmission assembly 25 can also be indirectly connected to the first deformation part 101 through an intermediate component. Figure 5 As shown, in one embodiment, the housing 10 further has a convex bulge 102, and the convex bulge 102 has a hollow cavity, which is connected to the main cavity of the housing 10. A portion of the transmission assembly 25 is accommodated in the convex bulge 102 and connected to the inner wall of the convex bulge 102. The first deformation portion 101 is located on the peripheral side of the convex bulge 102 and is connected to the edge of the convex bulge 102. In this way, the transmission assembly 25 is indirectly connected to the first deformation portion 101 through the convex bulge 102.

[0119] During the process of the first deformation part 101 sinking and rebounding into the interior of the shell 10, the first deformation part 101 can drive the convex bump 102 to move accordingly, thereby driving the transmission component 25 to move, and then the transmission component 25 converts the sinking-rebounding movement of the first deformation part 101 into the rotational movement of the first component 21.

[0120] When the structure of the transmission assembly 25 is different, the specific components of the transmission assembly 25 contained in the convex bump 102 are also different. Figure 5 As shown, in one embodiment, the sleeve 252 in the transmission assembly 25 can be accommodated in the cavity of the convex bump 102. For another example, Figure 7 As shown, in another embodiment, the end of the rack 253 in the transmission assembly 25 can be accommodated in the cavity of the convex hull 102. For another example, Figure 8 As shown, in yet another embodiment, the nut seat 257 in the transmission assembly 25 can be accommodated in the cavity of the convex hump 102 .

[0121] In the above embodiment, by accommodating a part of the transmission assembly 25 in the convex hump 102, the space occupied by the transmission assembly 25 in the main cavity of the housing 10 can be reduced, thereby providing a larger layout space for the first component 21, the second component 22, the power management device 30, and the power-consuming device 40. In addition, the inner wall of the convex hump 102 has a large surface area, and by connecting a part of the transmission assembly 25 to the inner wall of the convex hump 102, the fixing effect of the transmission assembly 25 can be increased. Optionally, the transmission assembly 25 can be bonded to the inner wall of the convex hump 102.

[0122] In the friction nano power generation device 20, the first friction power generation module 23 and the second friction power generation module 24 are arranged between the first component 21 and the second component 22. During the rotation of the first component 21 relative to the second component 22, the first friction power generation module 23 and the second friction power generation module 24 can generate electricity by friction. When the first friction power generation module 23 and the second friction power generation module 24 are specifically arranged, the first friction power generation module 23 and the second friction power generation module 24 include a variety of structural forms.

[0123] Fig. 9 A schematic diagram of the arrangement of a first friction power generation module provided in an embodiment of the present invention, Fig.10 A schematic diagram of the arrangement of the second friction power generation module provided in an embodiment of the present invention, Fig.11 A schematic diagram of the structure of a friction nano power generation device provided by an embodiment of the present invention. Fig. 9 , Fig.10 and Fig.11 In some embodiments, the first friction power generation module 23 includes a friction part 231, and the friction part 231 includes a polymer material and has insulation. The friction part 231 can be one or more. In the scenario where there are multiple friction parts 231, the multiple friction parts 231 can be arranged at intervals in the circumferential direction. The friction part 231 is located on the surface of the first component 21 facing the second component 22. During the rotation of the first component 21, the friction part 231 will rotate with the rotation of the first component 21.

[0124] The second friction power generation module 24 includes a first electrode portion 241 and a second electrode portion 242, which are located on the surface of the second component 22 facing the first component 21, and the first electrode portion 241 and the second electrode portion 242 are arranged at intervals along the circumferential direction. The number of the first electrode portion 241 and the second electrode portion 242 can be one or more. In the scenario where there are multiple first electrode portions 241 and / or second electrode portions 242, the first electrode portion 241 and the second electrode portion 242 are arranged alternately along the circumferential direction.

[0125] The first electrode portion 241 is connected to the power management device through a wire, and the second electrode portion 242 is also connected to the power management device through a wire. Fig.11 As shown, there are multiple first electrode parts 241 and second electrode parts 242, wherein the multiple first electrode parts 241 are connected to one end of the power management device through a wire, and the multiple second electrode parts 242 are connected to the other end of the power management device through a wire. During the relative rotation of the first component 21 and the second component 22, the friction part 231 contacts the first electrode part 241 and the second electrode part 242 in sequence. In this process, a potential difference is generated between the first electrode part 241 and the second electrode part 242, so that current is generated in the external circuit.

[0126] In a specific embodiment, the second component 22 is fixed, and accordingly, the first electrode portion 241 and the second electrode portion 242 are also fixed. When the first electrode portion 241 and the second electrode portion 242 are connected to the power management device respectively, the wire connected to the first electrode portion 241 can be fixed, and the wire connected to the second electrode portion 242 can also be fixed, so that wiring is easier and winding of the conductor during rotation is avoided.

[0127] Optionally, the friction part 231 is a film layer formed of a negative polarity material, and the first electrode part 241 and the second electrode part 242 are electrode layers formed of copper or aluminum. Alternatively, the friction part 231 is a film layer formed of a positive polarity material, and the first electrode part 241 and the second electrode part 242 are electrode layers formed of copper or aluminum, and the surfaces of the first electrode part 241 and the second electrode part 242 respectively have film layers formed of negative polarity materials. The above-mentioned negative polarity material can be polyimide, polytetrafluoroethylene or other electronegative materials, and the above-mentioned positive polarity material can be nylon, polyoxymethylene, ethyl cellulose or other electropositive materials, which are not listed one by one in this application.

[0128] Fig.12 Another structural diagram of the friction nano power generation device provided by the embodiment of the present invention is as follows: Fig.12As shown, in one embodiment, the first friction power generation module 23 includes a third electrode portion 232, and the third electrode portion 232 is connected to the power management device. The surface of the third electrode portion 232 facing away from the first component 21 is provided with a friction layer, and the friction layer includes a polymer material.

[0129] The second friction power generation module 24 includes a fourth electrode portion 243, which is also connected to the power management device. During the relative rotation of the first component 21 and the second component 22, the third electrode portion 232 and the fourth electrode portion 243 will contact and slip, so that a potential difference is generated between the third electrode portion 232 and the fourth electrode portion 243, thereby causing current to flow in the external circuit. Optionally, a friction layer can also be provided on the surface of the fourth electrode portion 243 facing away from the second component 22, and the friction layer contains a polymer material, and has a friction electrode sequence difference with the polymer material contained in the friction layer on the surface of the third electrode portion 232.

[0130] During the wiring, since the first component 21 is in a rotating state, the third electrode portion 232 will rotate with the rotation of the first component 21, thereby rotating the wire connected to the third electrode portion 232. In order to prevent the wires from being entangled, a conductive slip ring can be provided in the housing 10, so that the above-mentioned wires are respectively connected to the conductive slip rings, and the conductive slip rings are further connected to the external circuit, thereby preventing the above-mentioned wires from being entangled together during the rotation of the first component 21.

[0131] Of course, the first friction power generation module 23 and the second friction power generation module 24 also include other structural forms, which are not listed one by one in this application.

[0132] In addition to using the transmission assembly 25 to convert the depression-rebound motion of the first deformation part 101 into the rotational motion of the first component 21, the depression-rebound motion of the first deformation part 101 can also be directly used to make the first component 21 move linearly relative to the second component 22. In the following embodiments, this motion form will be specifically introduced.

[0133] Fig.13 Another schematic diagram of the internal structure of the self-powered monitoring device provided by the embodiment of the present invention is as follows: Fig.13 As shown, in one embodiment, the first component 21 is connected to the first deformation portion 101, and when the first deformation portion 101 switches between the depressed state and the rebound state, the first component 21 is used to perform linear motion relative to the second component 22 along the first direction X. The first direction X has a positive direction and a negative direction. If the positive direction of the first direction X is recorded as the direction in which the first component 21 moves with the depression of the first deformation portion 101, the negative direction of the first direction X is the direction in which the first component 21 moves with the rebound of the first deformation portion 101.

[0134] Please continue to refer to Fig.13 In one embodiment, the first component 21 has a first surface 210, and the second component 22 has a second surface 220. The first surface 210 and the second surface 220 are arranged opposite to each other, and the plane where the first surface 210 and the plane where the second surface 220 are located are respectively perpendicular to the first direction X. Driven by the first deformation portion 101, the first surface 210 and the second surface 220 will be relatively close to or relatively far away from each other.

[0135] In the above scenario, the first friction power generation module 23 and the second friction power generation module 24 can generate electricity in a vertical contact-separation mode. Fig.13 As shown, in one embodiment, the first friction power generation module 23 includes a third electrode portion 232, and the third electrode portion 232 is located on the first surface 210. The second friction power generation module 24 includes a fourth electrode portion 243, and the fourth electrode portion 243 is located on the second surface 220. The surface of the third electrode portion 232 and the surface of the fourth electrode portion 243 are respectively provided with two polymer material layers with different friction electrode sequences, and the surface of the third electrode portion 232 and the fourth electrode portion 243 are respectively connected to the power management device. During the relative movement of the first component 21 and the second component 22 along the first direction X, the third electrode portion 232 and the fourth electrode portion 243 will be in vertical contact-separation, so that a potential difference is generated between the third electrode portion 232 and the fourth electrode portion 243, and then a current is generated in the external circuit.

[0136] Fig.14 Another schematic diagram of the internal structure of the self-powered monitoring device provided by the embodiment of the present invention is as follows: Fig.14 As shown, this embodiment and Fig.13 The corresponding embodiments are similar in that the first component 21 is connected to the first deformation portion 101, and driven by the first deformation portion 101, the first component 21 can perform linear motion along the first direction X relative to the second component 22. Fig.13 The difference from the corresponding embodiment is that, in this embodiment, the plane where the first surface 210 of the first component 21 is located and the plane where the second surface 220 of the second component 22 is located are parallel to the first direction X respectively.

[0137] In the above scenario, the first friction power generation module 23 and the second friction power generation module 24 can generate electricity in a translational sliding mode. Fig.13 The structure of the first friction power generation module 23 in the embodiment shown is the same as that of the second friction power generation module 24. Fig.13 The structure of the second friction power generation module 24 in the illustrated embodiment is the same and will not be described in detail here.

[0138] When making specific arrangements, Fig.14As shown, the third electrode portion 232 in the first friction power generation module 23 is located on the first surface 210, and the fourth electrode portion 243 in the second friction power generation module 24 is located on the second surface 220. During the relative movement of the first component 21 and the second component 22 along the first direction X, the third electrode portion 232 and the fourth electrode portion 243 may be displaced, so that the area of ​​the portion where the third electrode portion 232 and the fourth electrode portion 243 face each other changes, thereby generating a potential difference between the third electrode portion 232 and the fourth electrode portion 243, and correspondingly generating a current in the external circuit.

[0139] In another embodiment in which the first friction power generation module 23 and the second friction power generation module 24 generate electricity in a translational sliding mode, the first friction power generation module 23 includes a friction portion 231, and the friction portion 231 is located on the first surface 210 of the first component 21. Optionally, the first surface 210 may be provided with a friction portion 231, or the first surface 210 may also be provided with a plurality of friction portions 231 spaced apart along the first direction X. The second friction power generation module 24 includes a first electrode portion 241 and a second electrode portion 242, and the first electrode portion 241 and the second electrode portion 242 are located on the second surface 220 of the second component 22, and the first electrode portion 241 and the second electrode portion 242 are alternately arranged along the first direction X.

[0140] When the first component 21 and the second component 22 move relative to each other along the first direction X, the friction portion 231 may alternately rub against the first electrode portion 241 and the second electrode portion 242 , thereby generating a potential difference between the first electrode portion 241 and the second electrode portion 242 , thereby generating current in the external circuit.

[0141] When the first component 21 is specifically fixed, the first component 21 can be directly connected to the first deformation portion 101, or the first component 21 can also be indirectly connected to the first deformation portion 101 through an intermediate component. In one embodiment, the shell 10 also has a convex bulge 102, and the convex bulge 102 has a hollow cavity. A portion of the first component 21 is accommodated in the convex bulge 102 and is connected to the inner wall of the convex bulge 102. The first deformation portion 101 is located on the peripheral side of the above-mentioned convex bulge 102 and is connected to the edge of the convex bulge 102. In this way, the first component 21 is indirectly connected to the first deformation portion 101 through the convex bulge 102.

[0142] Since the inner wall of the convex hump 102 has a large surface area, the fixing effect of the first component 21 can be increased by connecting the first component 21 to the inner wall of the convex hump 102. Optionally, the first component 21 can be bonded to the inner wall of the convex hump 102.

[0143] Fig.15 Another schematic diagram of the internal structure of the self-powered monitoring device provided by the embodiment of the present invention is as follows: Fig.15 As shown, in one embodiment, in addition to the first deformation part 101, the shell 10 also includes a second deformation part 103, and the second deformation part 103 and the first deformation part 101 are located at two opposite ends of the shell 10 along the first direction X. The second deformation part 103 also has a recessed state and a rebound state, and during the wave movement, the second deformation part 103 can switch between the recessed state and the rebound state. The second component 22 is connected to the second deformation part 103, and the second component 22 can move with the recessed-rebound movement of the second deformation part 103.

[0144] When the second deformation part 103 is specifically set, the material of the second deformation part 103 can be the same as the material of the first deformation part 101, that is, both include elastic material. The elastic material makes the second deformation part 103 more flexible, so that the second deformation part 103 is easier to be recessed into the inner cavity of the shell 10 under the action of water pressure. After the second deformation part 103 is recessed into the inner cavity of the shell 10, the second deformation part 103 will generate an elastic restoring force. When the pressure outside the shell 10 decreases, the second deformation part 103 can rebound under the action of the elastic restoring force. Optionally, the elastic material can be silicone, rubber or polyurethane.

[0145] In one application scenario, the first deformation portion 101 and the second deformation portion 103 can be recessed and rebounded simultaneously, so that the first component 21 and the second component 22 can slide in opposite directions, thereby increasing the relative displacement between the first component 21 and the second component 22 and improving power generation.

[0146] When the housing 10 is specifically configured, in one embodiment, the main body of the housing 10 can be made of a rigid material, and the first deformation portion 101 is made of an elastic material. Of course, when the housing 10 includes the second deformation portion 103, the second deformation portion 103 is also made of an elastic material. In another embodiment, the entire housing 10 is made of an elastic material. The housing 10 is made of the same material, thereby facilitating the manufacture of the housing 10.

[0147] In one embodiment, the shell 10 is a flexible shell, and the second component 22 of the friction nano power generation device 20 is supported on the inner wall of the shell 10, and the second component 22 avoids the first deformation part 101. On the one hand, the shell 10 can be supported by the second component 22, thereby providing a stable accommodation space for other internal structural parts, and on the other hand, the first deformation part 101 is allowed to generate a concave-rebound movement during the movement of the wave, thereby converting the wave energy into mechanical energy.

[0148] In a specific implementation, the housing 10 and the second component 22 have matching structures. For example, the inner wall of the housing 10 is a spherical inner wall, and accordingly, the second component 22 includes an annular support structure that can fit the inner wall of the housing 10 to support the housing 10.

[0149] Fig.16 Another structural schematic diagram of a housing provided by an embodiment of the present invention is shown in FIG. Fig.16 As shown, in one embodiment, in addition to the first deformation portion 101, the shell 10 also includes a connecting portion 104, and the connecting portion 104 is connected to the peripheral edge of the first deformation portion 101, and the thickness of the first deformation portion 101 is less than the thickness of the connecting portion 104, so that the first deformation portion 101 is more likely to be concavely deformed relative to the connecting portion 104.

[0150] The housing 10 may have a variety of shapes. Fig.16 The spherical shape is shown, but the housing 10 may also have other shapes. Figures 17 to 20 Several structural schematic diagrams of the housing provided by the embodiments of the present invention are as follows: Fig.17 and Fig.18 As shown, the housing 10 in both embodiments is spherical. The difference is that Fig.17 In the corresponding embodiment, the housing 10 has a convex hump 102 . Fig.18 In the corresponding embodiment, the housing 10 does not have the convex bump 102. Fig.19 As shown in FIG. 1 , in another embodiment, the housing 10 is ellipsoidal. Fig. 20 As shown, in yet another embodiment, the housing 10 is lantern-shaped.

[0151] In the above embodiments, the housing 10 includes a first housing 11 and a second housing 12. The first housing 11 and the second housing 12 present different shapes after being buckled. The first deformation portion 101 is located in the first housing 11. When the first deformation portion 101 is in a rebound state, the first deformation portion 101 has various shapes. Figures 17 to 19 As shown, in some embodiments, when the first deformation portion 101 is in a rebound state, the outer surface of the first deformation portion 101 is an arc surface, and the arc surface bulges in a direction away from the first component 21. Fig. 20 As shown, in another embodiment, when the first deformation portion 101 is in the rebound state, the outer surface of the first deformation portion 101 is a plane.

[0152] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
