DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0040] It should be understood that references throughout this specification to "one embodiment" or "an embodiment" mean that a particular feature, structure, or characteristic associated with the embodiment is included in at least one embodiment of the present application. Therefore, the appearances of "in one embodiment" or "in an embodiment" throughout this specification do not necessarily refer to the same embodiment. Furthermore, these particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0041] like Figures 1 to 4 As shown, the power generation device includes: a first fixing member 10 , a second fixing member 20 , a floating plate assembly 30 , a piezoelectric power generation element 40 and a power management module 50 .

[0042] The first and second fixing members 10, 20 are both fixed to the floating plate assembly 30, with the first and second fixing members 10, 20 spaced apart. A piezoelectric generator 40 has a first end connected to the first fixing member 10, and a second end connected to the second fixing member 20. Either the first or second end of the piezoelectric generator 40 is electrically connected to a power management module 50, which is used to electrically connect to a detection device. The floating plate assembly 30 is configured to float on the liquid surface. When the floating plate assembly 30 floats on the liquid surface, it causes the first and second fixing members 10, 20 to oscillate, causing the piezoelectric generator 40 to bend and generate electrical energy, which is then transferred to the power management module 50.

[0043] In the embodiment of the present application, since the first fixing member 10 and the second fixing member 20 are both fixed to the floating plate assembly 30, when the floating plate assembly 30 floats on the liquid surface, when the liquid surface sways, the floating plate assembly 30 will sway with the sway of the liquid surface, thereby causing the floating plate assembly 30 to cause the first fixing member 10 and the second fixing member 20 to sway. Since the first fixing member 10 and the second fixing member 20 are spaced apart, there is a gap between the first fixing member 10 and the second fixing member 20, thereby allowing the first end of the piezoelectric generator 40 to be connected to the first fixing member 10 and the second end of the piezoelectric generator 40 to be connected to the second fixing member 20. When the first fixing member 10 and the second fixing member 20 sway with the sway of the floating plate assembly 30, the first fixing member 10 and the second fixing member 20 will cause the piezoelectric generator 40 to sway and bend, causing the piezoelectric generator 40 to generate electrical energy. Since the first end or the second end of the piezoelectric generator 40 is electrically connected to the power management module 50, the electric energy generated by the piezoelectric generator 40 can be transmitted to the power management module 50. Therefore, when the detection device is electrically connected to the power management module 50, the power management module 50 can transmit the electric energy to the detection device to power the detection device. That is, in the embodiment of the present application, by arranging the first fixing member 10 and the second fixing member 20 on the floating plate assembly 30, and the first fixing member 10 and the second fixing member 20 are spaced apart, the two ends of the piezoelectric generator 40 are respectively connected to the first fixing member 10 and the second fixing member 20, so that after the floating plate assembly 30 is placed on the liquid surface, the floating plate assembly 30 shakes with the shaking of the liquid surface, so that the first fixing member 10 and the second fixing member 20 drive the piezoelectric generator 40 to bend, so that the piezoelectric generator 40 generates electrical energy, and the electrical energy generated by the piezoelectric generator 40 is transmitted to the power management module 50, and the power management module 50 can then transmit the electrical energy to the detection device to power the detection device, thereby making it more convenient to power the detection device.

[0044] It should be noted that in the embodiment of the present application, both the first fixing member 10 and the second fixing member 20 may be connectors. Furthermore, in the embodiment of the present application, the piezoelectric generator 40 may be a piezoelectric bimorph. The piezoelectric generator 40 may also be other devices that generate electrical energy by shaking or bending, and this embodiment of the present application does not limit this.

[0045] In addition, in the embodiment of the present application, the floating plate assembly 30 can be formed of a plastic plate. Of course, it can also be formed of other materials. For example, the floating plate assembly 30 is formed of foam. The embodiment of the present application does not limit the specific material of the floating plate assembly 30.

[0046] In addition, in an embodiment of the present application, the liquid surface can be the sea surface, that is, the power generation device is placed on the sea surface. When the sea surface shakes, that is, when the waves cause the sea surface to shake, the floating plate assembly 30 of the power generation device can shake with the shaking of the sea surface, thereby causing the piezoelectric generator 40 to bend and generate electrical energy.

[0047] In addition, in an embodiment of the present application, the detection device may include a sensor, a single-chip microcomputer and a radio frequency antenna. The sensor is electrically connected to the single-chip microcomputer, and the single-chip microcomputer is electrically connected to the radio frequency antenna. The power management module 50 can be electrically connected to the sensor and the single-chip microcomputer, thereby providing power to the sensor and the single-chip microcomputer. The sensor can then perform detection and send the detection results to the single-chip microcomputer. The single-chip microcomputer analyzes the detection results and then transmits the signal to the outside through the radio frequency antenna.

[0048] In addition, in the embodiment of the present application, the number of piezoelectric generators 40 can be set according to actual needs. For example, the number of piezoelectric generators 40 is 1, 2, or 3. The specific number of piezoelectric generators 40 is not limited in the embodiment of the present application.

[0049] In addition, in the embodiment of the present application, the piezoelectric generator 40 can be a single chip or a double chip, which is not limited in the embodiment of the present application.

[0050] In addition, in the embodiment of the present application, the power management module 50 can be fixed on the first floating plate 31 or on the second floating plate 32, which is not limited in the embodiment of the present application.

[0051] In addition, in some embodiments, the floating plate assembly 30 may include a first floating plate 31 and a second floating plate 32. The first floating plate 31 and the second floating plate 32 are spaced apart from each other, one end of the first fixing member 10 is fixed to the fixing surface of the first floating plate 31, and one end of the second fixing member 20 is fixed to the fixing surface of the second floating plate 32. The first surface of the first floating plate 31 is the surface opposite to the floating surface of the first floating plate 31, and the fixing surface of the second floating plate 32 is the surface opposite to the floating surface of the second floating plate 32.

[0052] Because the first and second floating plates 31 and 32 are spaced apart, a gap exists between them. Consequently, after the first and second floating plates 31 and 32 are placed on the liquid surface, they can approach each other as they sway with the liquid surface. Because one end of the first fixing member 10 is fixed to the fixing surface of the first floating plate 31, and one end of the second fixing member 20 is fixed to the fixing surface of the second floating plate 32, the distance between the first and second fixing members 10 and 20 decreases as the first and second floating plates 31 and 32 approach each other. Consequently, the first and second fixing members 10 and 20 simultaneously apply force to the piezoelectric generator 40, causing the piezoelectric generator 40 to bend under the force, thereby generating electrical energy. That is, by providing the first floating plate 31 and the second floating plate 32 , which are spaced apart from each other, the first fixing member 10 and the second fixing member 20 can be easily shaken to allow the piezoelectric generator 40 to bend and generate electricity.

[0053] In addition, in some embodiments, the distance between the first floating plate 31 and the second floating plate 32 is equal to the first preset distance, and the first preset distance is d1. Wherein, l is the length of the piezoelectric generator 40, r is the minimum curvature radius of the neutral layer of the piezoelectric generator 40, h1 is the distance between the piezoelectric generator 40 and the fixing surface of the first floating plate 31,

[0054] When the spacing between the first and second floating plates 31, 32 is equal to the first predetermined spacing, as the first and second floating plates 31, 32 sway with the liquid surface, the first and second floating plates 31, 32 cause the first and second fixing members 10, 20 to cause the piezoelectric generator 40 to bend. When the piezoelectric generator 40 bends to the maximum allowable stress, the first and second floating plates 31, 32 come into contact, causing the first and second floating plates 31, 32 to abut against each other, preventing the piezoelectric generator 40 from further bending. This prevents the piezoelectric generator 40 from bending beyond the maximum allowable stress, thus preventing stress overload and potentially damaging the piezoelectric generator 40. In other words, by setting the spacing between the first and second floating plates 31, 32 to be equal to the first predetermined spacing, damage to the piezoelectric generator 40 can be avoided.

[0055] It should be noted that the piezoelectric generator 40 generally includes three layers, the upper layer is the upper piezoelectric generator sheet, the middle layer is the neutral layer, and the lower layer is the lower piezoelectric generator sheet. Among them, t p is the thickness of the upper piezoelectric sheet or the lower piezoelectric sheet in the piezoelectric generator 40, t sis the thickness of the neutral layer in the piezoelectric generator 40, Y is the equivalent Young's modulus of the piezoelectric generator 40, σ p is the maximum allowable stress of the piezoelectric material used in the piezoelectric generator 40. In addition, in the embodiment of the present application, the length of the piezoelectric generator 40 is the distance between the first end and the second end of the piezoelectric generator 40.

[0056] For example, Figure 2 FIG. 4 is a schematic diagram showing a piezoelectric generator 40 when it is bent. Figure 2 Where l represents the length of the piezoelectric generator 40, h represents the distance between the piezoelectric generator 40 and the fixing surface of the first floating plate 31, It represents the angle between the first floating plate 31 and the horizontal plane when the first floating plate 31 and the second floating plate 32 are in contact.

[0057] In addition, in some embodiments, the floating plate assembly 30 may further include a third floating plate 33 and a fourth floating plate 34. The third floating plate 33 is spaced apart from the first floating plate 31, and the other end of the first fixing member 10 is fixed to the fixing surface of the third floating plate 33, which is the surface of the third floating plate 33 facing the first floating plate 31. The fourth floating plate 34 is spaced apart from the second floating plate 32, and the other end of the second fixing member 20 is fixed to the fixing surface of the fourth floating plate 34, which is the surface of the fourth floating plate 34 facing the second floating plate 32.

[0058] Because the third floating plate 33 is spaced apart from the first floating plate 31, and the other end of the first fixing member 10 is fixed to the fixing surface of the third floating plate 33, and the fourth floating plate 34 is spaced apart from the second floating plate 32, and the other end of the second fixing member 20 is fixed to the fixing surface of the fourth floating plate 34, when the power generation device is placed on the liquid surface, the third floating plate 33 and the fourth floating plate 34 can enhance the stability of the power generation device, thereby facilitating its floating on the liquid surface. In other words, the provision of the third floating plate 33 and the fourth floating plate 34 can improve the stability of the power generation device while floating on the liquid surface.

[0059] In addition, in some embodiments, the distance between the third floating plate 33 and the fourth floating plate 34 is equal to the second preset distance, and the second preset distance is d2. Wherein, l is the length of the piezoelectric generator 40, r is the minimum curvature radius of the neutral layer of the piezoelectric generator 40, h2 is the distance between the piezoelectric generator 40 and the fixed surface of the third floating plate 33, and θ is equal to

[0060] When the distance between the third floating plate 33 and the fourth floating plate 34 is equal to the second predetermined distance, as the first floating plate 31 and the second floating plate 32 sway with the liquid surface, the first floating plate 31 and the second floating plate 32 cause the first fixing member 10 and the second fixing member 20 to drive the piezoelectric generator 40 to bend. When the piezoelectric generator 40 bends to the maximum allowable stress, the first floating plate 31 and the second floating plate 32 come into contact, and the third floating plate 33 and the fourth floating plate 34 also come into contact, resulting in abutment between the first floating plate 31 and the second floating plate 32, and abutment between the third floating plate 33 and the fourth floating plate 34. This is equivalent to the contact between the third floating plate 33 and the fourth floating plate 34 further supplementing the contact force between the first floating plate 31 and the second floating plate 32, further preventing the piezoelectric generator 40 from excessive bending, thereby preventing the piezoelectric generator 40 from bending beyond the maximum allowable stress, preventing stress overload on the piezoelectric generator 40, and avoiding damage to the piezoelectric generator 40. That is, by setting the distance between the third floating plate 33 and the fourth floating plate 34 to be equal to the second preset distance, the problem of the piezoelectric generator 40 being damaged can be further avoided.

[0061] It should be noted that in the embodiment of the present application, when the floating plate assembly 30 includes a first floating plate 31, a second floating plate 32, a third floating plate 33, and a fourth floating plate 34, the first preset spacing between the first floating plate 31 and the second floating plate 32 can be equal to the second preset spacing between the third floating plate 33 and the fourth floating plate 34. Of course, the first preset spacing and the second preset spacing can also be different, and this embodiment of the present application is not limited to this.

[0062] In addition, in some embodiments, the power generation device may further include a first photovoltaic panel 60, a second photovoltaic panel 70, and a photovoltaic interface circuit 80. The first photovoltaic panel 60 is mounted on the mounting surface of the third floating plate 33, which is the surface of the third floating plate 33 facing away from the first floating plate 31. The second photovoltaic panel 70 is mounted on the mounting surface of the fourth floating plate 34, which is the surface of the fourth floating plate 34 facing away from the second floating plate 32. The first photovoltaic panel 60 and the second photovoltaic panel 70 are both electrically connected to the photovoltaic interface circuit 80. The first photovoltaic panel 60 and the second photovoltaic panel 70 transmit the generated electrical energy to the photovoltaic interface circuit 80, which is electrically connected to the detection device.

[0063] Because the first photovoltaic panel 60 is mounted on the mounting surface of the third floating plate 33, and the second photovoltaic panel 70 is mounted on the mounting surface of the fourth floating plate 34, after the power generation device is placed on the liquid surface, both the first photovoltaic panel 60 and the second photovoltaic panel 70 are exposed to light, thereby generating electrical energy. Because both the first photovoltaic panel 60 and the second photovoltaic panel 70 are electrically connected to the photovoltaic interface circuit 80, the electrical energy generated by the first photovoltaic panel 60 and the second photovoltaic panel 70 can be transmitted to the photovoltaic interface circuit 80, and then transmitted to the detection device through the photovoltaic interface circuit 80 to power the detection device. That is, by setting up the first photovoltaic panel 60 and the second photovoltaic panel 70, the first photovoltaic panel 60 and the second photovoltaic panel 70 can also generate electrical energy to power the detection device, thereby increasing the power supply path for the detection device. Even if the amplitude of the liquid surface shaking is small, resulting in less electrical energy generated by the piezoelectric generator 40, the first photovoltaic panel 60 and the second photovoltaic panel 70 can generate electrical energy as a supplement to the power supply for the detection device, ensuring that the detection device can operate normally.

[0064] It should be noted that the number of first photovoltaic panels 60 can be set according to actual needs. For example, the number of first photovoltaic panels 60 can be one or two. The embodiment of the present application does not limit the number of first photovoltaic panels 60. In addition, the number of second photovoltaic panels 70 can be equal to the number of first photovoltaic panels 60, thereby improving the aesthetics of the power generation device.

[0065] In addition, in some embodiments, the photovoltaic interface circuit 80 may include a power adjustment module 81 and a voltage stabilization module 82. The power adjustment module 81 is electrically connected to the voltage stabilization module 82, and both the first photovoltaic panel 60 and the second photovoltaic panel 70 are electrically connected to the power adjustment module 81. The voltage stabilization module 82 is electrically connected to the detection device. The power adjustment module 81 is used to adjust the power of the output electrical energy to match the power of the detection device; the voltage stabilization module 82 is used to adjust the voltage transmitted to the detection device to maintain a constant voltage.

[0066] Since the power adjustment module 81 is electrically connected to the voltage stabilizing module 82, the first photovoltaic panel 60 and the second photovoltaic panel 70 are both electrically connected to the power adjustment module 81. Therefore, the electric energy generated by the first photovoltaic panel 60 and the second photovoltaic panel 70 can be transmitted to the power adjustment module 81, and the power adjustment module 81 can adjust the power of the electric energy, that is, adjust the power of the electric energy output by itself, so that the power of the output electric energy matches the power of the detection device. In addition, after the power adjustment module 81 adjusts the power of the electric energy output by itself, the electric energy will be transmitted to the voltage stabilizing module 82. The voltage stabilizing module 82 can adjust the voltage of the electric energy transmitted to the detection device so that the voltage transmitted to the detection device is a constant voltage, that is, the detection device is powered by a constant voltage, which is beneficial to powering the detection device.

[0067] It should be noted that the specific types of the power adjustment module 81 and the voltage stabilization module 82 can be set according to actual needs. For example, the power adjustment module 81 and the voltage stabilization module 82 are two modules in the bq25505 chip. Of course, they can also be other types of modules. The specific types of the power adjustment module 81 and the voltage stabilization module 82 are not limited in the embodiments of the present application.

[0068] In addition, in some embodiments, the power management module 50 may include a current conversion module 51 and a locking module 52. The current conversion module 51 and the locking module 52 are electrically connected, with the current conversion module 51 being electrically connected to the first end or the second end of the piezoelectric generator 40. The locking module 52 is configured to be electrically connected to the detection device. The current conversion module 51 is configured to convert the alternating current generated by the piezoelectric generator 40 into direct current. The locking module 52 is configured to be closed when the current transmitted to the locking module 52 is less than a current threshold, and to be open when the current transmitted to the locking module 52 is greater than or equal to the current threshold, thereby transmitting current to the detection device. Alternatively, the locking module 52 is configured to be closed when the voltage transmitted to the locking module 52 is less than a voltage threshold, and to be open when the voltage transmitted to the locking module 52 is greater than or equal to the voltage threshold, thereby transmitting voltage to the detection device.

[0069] Because the current conversion module 51 and the locking module 52 are electrically connected, and the current conversion module 51 is electrically connected to the first end or the second end of the piezoelectric generator 40, the electrical energy generated by the piezoelectric generator 40 can be transmitted to the current conversion module 51, and the alternating current generated by the piezoelectric generator 40 can be transmitted to the current conversion module 51. The current conversion module 51 converts the alternating current into direct current suitable for the detection device. The direct current or voltage can then be transmitted to the locking module 52. After receiving the direct current or voltage, if the direct current current is less than a current threshold, or the voltage is less than a voltage threshold, the locking module 52 is in a closed state, meaning that the direct current is not transmitted to the detection device. If the direct current current is greater than or equal to the current threshold, or the voltage is greater than or equal to the voltage threshold, the locking module 52 is in a conducting state, and the direct current is transmitted to the detection device, powering the detection device. That is, by setting up the current conversion module 51, alternating current can be converted into direct current, which is beneficial for the detection device to operate based on direct current. By setting up the locking module 52, the current transmitted to the detection device can be larger, avoiding the problem of small current affecting the operation of the detection device.

[0070] It should be noted that the specific types of the current conversion module 51 and the locking module 52 can be set according to actual needs. For example, the current conversion module 51 and the locking module 52 are two units of the LTC3331 chip. Of course, they can also be other types of units. The specific types of the current conversion module 51 and the locking module 52 are not limited in the embodiments of the present application.

[0071] In addition, in some embodiments, the power generation device may further include an energy storage module. The energy storage module includes an energy storage capacitor and a battery, both of which are electrically connected to the power management module 50. Both of the energy storage capacitor and the battery are used to be electrically connected to the detection device. The power management module 50 is used to transfer electrical energy to the capacitor and / or battery so that the capacitor and / or battery can power the detection device.

[0072] When both the energy storage capacitor and the battery are electrically connected to the detection device, they can both deliver electrical energy to the detection device. Specifically, when the voltage of the power management module 50 is within a set first voltage range, the energy storage capacitor can first supply power to the detection device, delivering electrical energy to the detection device at a higher power, allowing the detection device to receive high-power electrical energy. When the voltage of the power management module 50 is within a set second voltage range, the battery can supply power to the detection device. The battery can supply power to the detection device for a long period of time, thereby ensuring that the detection device can perform detection for a long period of time.

Since the first fixing member 10 and the second fixing member 20 are spaced apart, there is a gap between the first fixing member 10 and the second fixing member 20, thereby allowing the first end of the piezoelectric generator 40 to be connected to the first fixing member 10 and the second end of the piezoelectric generator 40 to be connected to the second fixing member 20. When the first fixing member 10 and the second fixing member 20 sway with the sway of the floating plate assembly 30, the first fixing member 10 and the second fixing member 20 will cause the piezoelectric generator 40 to sway and bend, causing the piezoelectric generator 40 to generate electrical energy. Since the first end or the second end of the piezoelectric generator 40 is electrically connected to the power management module 50, the electric energy generated by the piezoelectric generator 40 can be transmitted to the power management module 50. Therefore, when the detection device is electrically connected to the power management module 50, the power management module 50 can transmit the electric energy to the detection device to power the detection device. That is, in the embodiment of the present application, by arranging the first fixing member 10 and the second fixing member 20 on the floating plate assembly 30, and the first fixing member 10 and the second fixing member 20 are spaced apart, the two ends of the piezoelectric generator 40 are respectively connected to the first fixing member 10 and the second fixing member 20, so that after the floating plate assembly 30 is placed on the liquid surface, the floating plate assembly 30 shakes with the shaking of the liquid surface, so that the first fixing member 10 and the second fixing member 20 drive the piezoelectric generator 40 to bend, so that the piezoelectric generator 40 generates electrical energy, and the electrical energy generated by the piezoelectric generator 40 is transmitted to the power management module 50, and the power management module 50 can then transmit the electrical energy to the detection device to power the detection device, thereby making it more convenient to power the detection device.

Since the first fixing member 10 and the second fixing member 20 are spaced apart, there is a gap between the first fixing member 10 and the second fixing member 20, thereby allowing the first end of the piezoelectric generator 40 to be connected to the first fixing member 10 and the second end of the piezoelectric generator 40 to be connected to the second fixing member 20. When the first fixing member 10 and the second fixing member 20 sway with the sway of the floating plate assembly 30, the first fixing member 10 and the second fixing member 20 will cause the piezoelectric generator 40 to sway and bend, causing the piezoelectric generator 40 to generate electrical energy. Since the first end or the second end of the piezoelectric generator 40 is electrically connected to the power management module 50, the electric energy generated by the piezoelectric generator 40 can be transmitted to the power management module 50. Therefore, when the detection device is electrically connected to the power management module 50, the power management module 50 can transmit the electric energy to the detection device to power the detection device.
