When the vibrating box 1 receives external excitation (including but not limited to vibration), the mass 12 will vibrate (upwards or downwards), and when the mass 12 vibrates downwards, the elastic element 13 will further sink downwards from an initial state, so that the first liquid 11 inside the vibrating box 1 is squeezed, wherein the initial state refers to a position where the elastic element 13 is located when the mass 12 is in a static state, and at this time, the elastic element 13 has an initial height in the up-down direction, and the height of the water level of the first liquid 11 is higher than or equal to the initial height, that is, the height of the water level of the first liquid 11 can be ensured to be higher than the height where the elastic element 13 sinks downwards under the vibration of the mass 12, and optionally, the height of the elastic element 13 refers to a height H where the lowest point of the elastic element 13 is located.

For example, when the power generation device is used in bridge engineering, it can be designed reasonably according to the vibration frequency range of the bridge deck and the wind speed of the local wind load, so that the mass block 12 can vibrate as much as possible under the general excitation condition of the environment. Alternatively, mass 12 is fabricated from a dense, corrosion resistant material such as corrosion resistant cast iron. Alternatively, the elastic member 13 may be configured in the shape of a film, and may be made of an elastic material with good corrosion resistance, including but not limited to one or more of silicone rubber material, polyester elastomer, acryl elastomer, and vinyl elastomer.

In this embodiment, the vibration box 1 is in an inverted circular truncated cone shape, and other embodiments may have other shapes, so that the volume of the side of the vibration box 1 close to the first channel 3 is smaller than the volume of the side close to the mass block 12, that is, the volume of the top of the vibration box 1 is larger than the volume of the portion provided with the first opening 14, the compressed volume of the first liquid 11 can be increased, and when the elastic member 13 at the top of the vibration box 1 is depressed downwards under the effect of the downward vibration of the mass block 12 to compress the first liquid 11, more first liquid 11 can flow into the first channel 3 through the first opening 14.

Referring to fig. 1, in the present embodiment, the first tank 2 contains the second liquid 21, and the first tank 2 has a third opening 22 and a fourth opening 23. Optionally, the second liquid 21 is the same as the first liquid 11 and is water, and in other embodiments the second liquid 21 may be different from the first liquid 11. The height of the fourth opening 23 is higher than the height of the third opening 22. Optionally, the first tank 2 is filled with a second liquid 21.

Referring to fig. 1 and 2, in the present embodiment, the first check valve 5, the second check valve 6, the third check valve 7, and the fourth check valve 8 refer to one-way conduction valves, and optionally may adopt a brass stop valve or other check valves capable of achieving one-way conduction, as shown in fig. 2, the check valve has a first end a, a second end B, a baffle C, and a spring D, and the one-way conduction refers to that substances (e.g., the first liquid 11 and the second liquid 21) can only enter the second end B from the first end a, and when a pressure required for opening the check valve (i.e., a force required for opening the baffle C) is satisfied, the substances (e.g., the first liquid 11 and the second liquid 21) can only enter the second end B from the first end a, i.e., the force received by the baffle C at the first end a is greater than the force received by the second end B; and when the check valve is in an open state, the pressure required for opening the check valve is not met, and the baffle C returns to the original position under the action of the spring D, namely the check valve is closed. In the present embodiment, the first check valve 5, the second check valve 6, the third check valve 7, and the fourth check valve 8 may be provided with springs D having different elastic coefficients according to actual conditions, so as to control different pressures required for opening the first check valve 5, the second check valve 6, the third check valve 7, and the fourth check valve 8, respectively.

Referring to fig. 1, in the present embodiment, the conducting direction of the first check valve 5 is the same as the conducting direction of the second check valve 6, and the conducting direction refers to the direction from the vibration box 1 to the first box 2, i.e. the direction to make the first liquid 11 flow from the vibration box 1 to the first box 2; the conducting direction of the third one-way valve 7 is the same as the conducting direction of the fourth one-way valve 8, and the conducting direction refers to the direction from the first box 2 to the vibrating box 1, namely the direction that the second liquid 21 can flow from the first box 2 to the vibrating box 1. Wherein the first liquid 11 includes, but is not limited to, the liquid located in the vibration box 1 and the first channel 3 at a certain moment, and the second liquid 21 includes, but is not limited to, the liquid located in the first box 2 and the second channel 4 at a certain moment. For example, when the power generating device is operated for a period of time, the first liquid 11 is E liquid, the second liquid 21 is F liquid, the E liquid initially located in the vibration box 1 enters the first channel 3 and the first box 2, and the F liquid initially located in the first box 2 enters the second channel 4 and the vibration box 1, then the first liquid 11 contains E liquid and F liquid, and the second liquid 21 also contains E liquid and F liquid.

Referring to fig. 1, in the present embodiment, the first check valve 5 is disposed at the first opening 14 between the vibration box 1 and the first passage 3, and the pressure required to open the first check valve 5 is set to be smaller than the pressure to which the first check valve 5 is subjected when the mass 12 vibrates downward (i.e., the pressure to which the first check valve 5 is close to the first opening 14 side when the mass 12 vibrates downward to cause the elastic member 13 to sag downward and compress the first liquid 11), so that the first check valve 5 is opened when the mass 12 vibrates downward.

Referring to fig. 1, in the present embodiment, the second check valve 6 is disposed at the third opening 22, and is located between the first tank 2 and the first channel 3, the pressure required to open the second check valve 6 is set to be smaller than the pressure that the second check valve 6 receives when the first channel 3 is filled with the first liquid 11 (i.e., the pressure that the second check valve 6 receives on the side close to the first channel 3 when the first channel 3 is filled with the first liquid 11), and the pressure required to open the second check valve 6 is the force required to overcome the sum of the elastic force of the spring D and the pressure of the second liquid 21 on the second check valve 6; with the above arrangement, the second check valve 6 is opened when the first liquid 11 fills the first passage 3. Alternatively, the second check valve 6 and the third opening 22 may be provided at the middle of the first tank 2.

Referring to fig. 1, in the present embodiment, the third check valve 7 is disposed at the fourth opening 23 between the first tank 2 and the second passage 4, the height of the water level of the second liquid 21 is set to be higher than or equal to the height of the third check valve 7, and the height of the water level of the second liquid 21 is higher than or equal to the height of the fourth opening 23. The pressure required to open the third check valve 7 is set to be less than the pressure to which the third check valve 7 is subjected when the second check valve 6 is opened (i.e., the pressure to which the third check valve 7 is subjected on the side close to the first tank 2, optionally the pressure to which the third check valve 7 is subjected on the side close to the first tank 2 when the first tank 2 is filled with the second liquid 21), so that when the second check valve 6 is opened, the third check valve 7 is opened while the first liquid 11 flows from the first passage 3 into the first tank 2 (e.g., when the first tank 2 is previously filled with the second liquid 21), or when the second check valve 6 is opened, the third check valve 7 is opened after a certain time (e.g., when the first tank 2 is not previously filled with the second liquid 21) while the first liquid 11 flows from the first passage 3 into the first tank 2.

Referring to fig. 1, in the present embodiment, the fourth check valve 8 is disposed at the second opening 15 between the vibration housing 1 and the second passage 4. When the mass block 12 vibrates upwards to deform the elastic piece 13 upwards to restore the initial state, the pressure difference between the vibration box body 1 and the second channel 4 is greater than the pressure required for opening the fourth check valve 8; thus, when the mass 12 vibrates upward, the pressure difference between the vibration box 1 and the second channel 4 caused by the outflow of the first liquid 11 inside the vibration box 1 can open the fourth check valve 8, so that the second liquid 21 inside the second channel 4 flows into the vibration box 1.

Referring to fig. 1, it can be understood that the volumes of the vibration housing 1, the first passages 3, the second passages 4 and the first housing 2 can be adjusted according to actual needs, so that when the mass vibrates downward, the volume of the first liquid 11 flowing into all the first passages 3 is larger than the sum of the volumes of all the first passages 3, and the second liquid 21 can flow into the vibration housing 1 through the second passages 4.

Referring to fig. 1, alternatively, in an initial state, the first liquid 11 is filled in the vibration housing 1, the first housing 2 is filled with the second liquid 21, and neither the first passage 3 nor the second passage 4 is filled with liquid.

Referring to fig. 1, the specific operation of the power generation apparatus is described in detail as follows: when the mass block 12 vibrates downwards to deform the elastic piece 13 downwards, the first liquid 11 is squeezed, so that the first one-way valve 5 is opened, the first liquid 11 flows into the first channel 3 through the first opening 14, so that the power generation equipment 9 in the first channel 3 generates power, when the first channel 3 is filled with the first liquid 11, the second one-way valve 6 is opened, so that the first liquid 11 flows into the first box 2 from the first channel 3 through the third opening 22, so that the third one-way valve 7 is opened, and the second liquid 21 flows into the second channel 4 from the first box 2 through the fourth opening 23, so that the power generation equipment 9 in the second channel 4 generates power; and when the mass 12 vibrates upward to restore the elastic member 13 to the original state, the fourth check valve 8 is opened due to the pressure difference between the vibration chamber 1 and the second passage 4 caused by the outflow of the first liquid 11 inside the vibration chamber 1, so that the second liquid 21 flows into the vibration chamber 1 from the second passage 4 through the second opening 15.

Based on the arrangement of the power generation device, a circulation backflow system is formed, the first liquid 11 and the second liquid 21 in the vibration box body 1 and the first box body 2 are recycled, external supplement is not needed, the power generation device is fixed at the lower part of the bridge deck of the bridge, repeated vertical vibration of the bridge in the using process can be utilized, the mass block 12 also vibrates vertically, the mass block 12 keeps a vibration state for a long time, and then the power generation equipment 9 in the first channel 3 and the second channel 4 is driven to work efficiently for a long time, and considerable electric energy is generated continuously.

In other embodiments, the combination of the first passage, the first check valve, and the second check valve may be swapped with the combination of the second passage, the third check valve, and the fourth check valve. The second channel may not be provided with power generation equipment, or the first one-way valve and the second one-way valve are in one-way conduction from the first box body to the vibrating box body, and the third one-way valve and the fourth one-way valve are in one-way conduction from the vibrating box body to the first box body. At this time, when the mass block vibrates downwards to enable the first liquid to be squeezed, the fourth one-way valve is opened to enable the first liquid to pass through the second channel, but when the second channel is filled with the first liquid, the third one-way valve is opened to enable the second one-way valve to be opened, and when the first channel is filled with the second liquid or when the mass block vibrates upwards, the first one-way valve is opened due to the pressure difference existing between the vibration box body and the first channel. Optionally, the first opening is disposed at a position at a height between the bottom of the vibration box and the height of the second channel.

In other embodiments, the second passage 4 may be provided without the power generation device 9, or without the fourth check valve 8.

In other embodiments, the fourth opening 23 and the second opening 15 may be made accessible on the basis of the first channel 3 being retained, i.e. the second channel 4 may be regarded as a channel (opening) of negligible length, optionally in some embodiments the fourth one-way valve 8 and/or the third one-way valve 7 may also be absent.

This scheme still provides a system, including foretell power generation facility, energy memory and consumer, energy memory connects power generation facility 9 and consumer.

Alternatively, the energy storage arrangement includes, but is not limited to, a battery and a super capacitor, connected to the power generation device 9 through a rectifying element, for collecting the electrical energy generated by the power generation device 9.

Optionally, the powered device includes, but is not limited to, a wireless sensor or the like.

The scheme also provides a method which is applied to the power generation device and comprises the following steps:
