Dampers are devices used to provide resistance to movement and to dissipate energy from movement. At present, most shock absorbers for vehicles use hydraulic dampers, which utilize a piston rod to move in a hydraulic cylinder to push hydraulic oil to flow from one cavity into another cavity through a small hole in the piston, so that friction loss is generated to consume energy generated by pushing the piston rod to move by external force. However, the hydraulic damper has the defect of non-adjustable damping, the market puts higher and higher requirements on the comfort and the performance of the vehicle, and the adjustable damping shock absorber is more and more emphasized.
On the other hand, the existing dampers basically form damping by means of energy consumption and heat generation, and the energy waste is large, so that energy recovery by utilizing hydraulic oil flow of the dampers is proposed. Japanese patent application No. JP2015180574A proposes a regenerative shock absorber, which designs a hydraulic passage of a damper of the shock absorber as an external pipe, adds a hydraulic motor in the pipe, and drives the hydraulic motor to drive a generator to generate electricity by hydraulic oil flowing back and forth in the pipe. Chinese invention patent No. CN104389753B, similar to japanese patent application No. JP2015180574A, divides an external pipe into two paths, and separately controls two hydraulic motors through a check valve to recover energy in two directions in vibration. WO patent publication No. WO2015127800a1 also uses a similar technique, except that a hydraulic motor is replaced by turbine blades, and two reciprocating pipelines are connected to a turbine shell in a staggered manner, so that hydraulic flows in two directions drive the turbine blades to rotate in the same direction, and the turbine drives a generator to generate electricity.
On the other hand, wave power generation is taken as clean energy, more and more attention is paid, the wave power generation device is still in a preliminary stage at present, the wave power generation device is various, most of the wave power generation device are complex in structure, small-sized equipment with low power generation efficiency and small total power is difficult to form large-scale popularization and application.

To those skilled in the art, the specific meanings of the above terms in the present invention can be understood in light of the present general concepts, in connection with the specific context of the scheme.
Example one
A damper 1 is provided, as shown in fig. 1, which includes a cylinder 11, a piston 12, and a piston rod 13. Wherein, the cylinder body 11 is wholly cylindrical, and the bottom is sealed and fixedly connected with bottom connects 14 on the outer wall, and the top of cylinder body 11 is opened and detachable is connected with the cylinder cap, for example screw or bolted connection. The piston 12 is disposed inside the cylinder 11 and divides the cylinder 11 into two independent chambers, i.e., a bottom chamber and a top chamber. The bottom end of the piston rod 13 is fixedly connected to one side of the piston 12, the top end of the piston rod 13 extends out of the cylinder 11 after passing through a piston hole in the cylinder cover, and the top end of the piston rod 13 is fixedly connected with a top connector 15.
The damper 1 in this embodiment further includes an adjustable damping system, the adjustable damping system includes a main pipeline 16 and a main adjustable valve 17, two ends of the main pipeline 16 are respectively communicated with two ends of the cylinder 11, and the main adjustable valve 17 is installed on the main pipeline 16 to adjust the flow velocity and flow rate of the fluid in the main pipeline 16. In this embodiment, the bottom side wall of the cylinder 11 and the cylinder cover are provided with interfaces so as to connect two ends of the main pipeline 16, so that the bottom chamber and the top chamber are communicated through the main pipeline 16. Regarding the installation of the main adjustable valve 17, in this embodiment, a cut-off portion is provided on the main pipeline 16, and two ports of the main adjustable valve 17 are hermetically connected to the cut-off portion of the main pipeline 16; alternatively, in another embodiment, the main pipeline 16 may be understood as two segmented pipelines, one port of each segmented pipeline is connected with the interface on the bottom of the cylinder 11 and the cylinder cover, and the other port of each segmented pipeline is connected with the two ports of the main adjustable valve 17, so as to form the adjustable damping system. In this embodiment, the main adjustable valve 17 may be a manual stop valve, or may be an electric valve or an electromagnetic valve, and adjusts the flow rate of the fluid in the main pipeline 16 by controlling the opening and closing degree of the main adjustable valve.
When in use:
1. if the piston rod 13 and the cylinder 11 are relatively static, the pressure of the bottom cavity and the pressure of the top cavity of the cylinder 11 are equal, and the piston 12 is in a balanced state;
2. if the piston rod 13 pushes the piston 12 to displace to one side of the bottom cavity of the cylinder 11, the volume of the bottom cavity in the cylinder 11 decreases, the fluid in the bottom cavity is compressed, the pressure of the bottom cavity increases, meanwhile, the volume of the top cavity on the other side in the cylinder 11 increases, the fluid in the top cavity expands, the pressure of the top cavity decreases, and as the bottom cavity and the top cavity of the cylinder 11 are communicated through the main pipeline 16, the pressure difference of the cavities on both sides of the piston 12 pushes the fluid to flow from the bottom cavity in the cylinder 11 to the top cavity through the main pipeline 16, so that the pressures of the cavities on both sides of the piston 12 reach a balanced state again;
3. if the piston rod 13 pushes the piston 12 to displace to a certain extent towards one side of the top cavity of the cylinder 11, the volume of the top cavity in the cylinder 11 decreases, the fluid in the top cavity is compressed, the pressure of the top cavity rises, meanwhile, the volume of the bottom cavity at the other side of the cylinder 11 increases, the fluid in the bottom cavity expands, the pressure of the bottom cavity decreases, because the bottom cavity and the top cavity of the cylinder 11 are communicated through the main pipeline 16, the pressure difference of the cavities at the two sides of the piston 12 pushes the fluid to flow into the bottom cavity from the top cavity of the cylinder structure through the main pipeline 16, and the pressures of the cavities at the two sides of the piston 12 reach a balanced state again.
Generally, since the inner diameter of the main pipeline 16 is smaller than that of the cylinder 11, the fluid flows in the main pipeline 16 faster than that in the cylinder 11, the fluid is accelerated, the work of the external force acting on the piston 12 is converted into the kinetic energy of the fluid, and the energy is consumed by the friction between the molecular interior of the fluid and the friction between the fluid and the inner wall of the main pipeline 16, so as to achieve the damping effect;
in addition, when the fluid passes through the main adjustable valve 17 on the main pipeline 16, the flow rate of the fluid in the main pipeline 16 can be controlled by adjusting the opening degree of the main adjustable valve 17. That is, when the opening degree of the main adjustable valve 17 is large, the ratio of the sectional area of the main adjustable valve 17 to the sectional area of the main pipeline 16 is large, the increase of the speed of the fluid flowing through the main adjustable valve 17 is relatively small, and the damping is small; when the opening degree of the main adjustable valve 17 is small, the ratio of the sectional area of the main adjustable valve 17 to the sectional area of the main pipeline 16 is small, the speed of the fluid flowing through the main adjustable valve 17 is increased relatively greatly, and the damping is increased. Therefore, the purpose of adjusting the damping effect of the damper 1 by adjusting the opening degree of the main adjustable valve 17 is achieved.
In the present embodiment, the fluid may be air, carbon dioxide, nitrogen, or other gas, or water, animal oil, vegetable oil, mineral oil, synthetic oil, or other liquid.
In another embodiment, in order to improve the automation level of damping adjustment in the damper, the damper is further provided with a valve control system 18, and the valve control system 18 comprises a valve controller and a valve actuator, wherein the valve actuator is in driving connection with the main adjustable valve, and usually, the valve actuator and the main adjustable valve are combined to form a pneumatic, electric or hydraulic actuator. The valve controller is in communication connection with the valve actuating mechanism, so that the actuator adjusts the opening degree after responding to a control signal of the valve controller, and the flow rate and the flow velocity of the controlled fluid medium are changed.
Example two
There is provided a mechanical energy damper 20, as shown in fig. 2, comprising the damper 1 disclosed in the first embodiment above and a mechanical energy conversion device 21, the mechanical energy conversion device 21 being mounted on the main pipeline 16 to convert pressure energy of fluid in the main pipeline 16 into mechanical energy. In this embodiment, the mechanical energy conversion device 21 is configured as a turbine device, such as a shaft turbine, but may be a shaftless blade turbine in another embodiment.
EXAMPLE III
On the basis of the second embodiment, it can be understood that, since there are two flow directions of the fluid in the damper 1, the output shaft of the mechanical energy conversion device 21 has two rotation directions, and there is a difference between the forward rotation and the reverse rotation when in use. It is often desirable to maintain consistency in power output during mechanical transmissions. In this embodiment, therefore, the arrangement further comprises a sensor 23, a commutation controller 24 and a commutation mechanism 25.
Wherein the sensor 23 is mounted on the main pipeline 16 to detect a flow direction of the fluid in the main pipeline 16; the reversing controller 24 is connected to the sensor 23 and the reversing mechanism 25 in communication, the reversing controller 24 is configured to control the reversing mechanism 25 to operate according to the flow direction of the fluid detected by the sensor 23, and the reversing mechanism 25 is configured to adjust the flow direction of the fluid in the main pipeline 16 to control the rotation direction of the output shaft of the mechanical energy conversion device 21.
In this embodiment, the reversing mechanism 25 is specifically configured as a reversing valve, as shown in fig. 3, for example, the reversing valve is a two-position four-way solenoid valve, and the reversing valve includes A, B, P, T four ports, where the P port and the T port are respectively connected to two ends of the cylinder 11 (i.e., the P port is connected to the port at the bottom of the cylinder 11, and the T port is connected to the port on the cylinder head), and the a port and the B port are respectively connected to two ends of the main pipeline 16 (the B port is connected to an upstream port of the main pipeline 16 that causes the turbine device to rotate in the forward direction, and the a port is connected to a downstream port of the main pipeline 16 that. Therefore, in this embodiment, the reversing valve adjusts the communication relationship between the ports a and B and the ports P and T, so as to adjust the flow direction of the fluid in the main pipeline 16, and further control the rotation direction of the output shaft of the mechanical energy conversion device 21.
When in use: the fluid flowing from the interface B to the interface a is in the forward direction, and the rotation direction of the output shaft of the mechanical energy conversion device 21 is in the forward direction, so that,
1. if the piston rod 13 pushes the piston 12 to move forward in the cylinder 11 (i.e. the piston 12 moves to the top chamber side), the fluid in the piston flows into the main pipeline 16, the sensor 23 acquires the flow direction information of the fluid in the main pipeline 16 and feeds the flow direction information back to the reversing controller 24, and the reversing controller 24 adjusts the state of the reversing mechanism 25 (i.e. the reversing valve) to make the reversing valve switch to: the interface B is communicated with the interface T, and the interface A is communicated with the interface P. At this time, the fluid flows into the mechanical energy conversion device 21 (i.e. the turbine device) through the main pipeline 16, and drives the turbine device to rotate in the forward direction;
2. if the piston rod 13 pushes the piston 12 to move in the cylinder 11 in the opposite direction (i.e. the piston 12 moves towards the bottom chamber side), the fluid in the piston rod flows into the main pipeline 16, the sensor 23 acquires the flow direction information of the fluid in the main pipeline 16 and feeds the flow direction information back to the reversing controller 24, and the reversing controller 24 adjusts the state of the reversing mechanism 25 (i.e. the reversing valve) to make the reversing valve switch to: the interface B is communicated with the interface P, and the interface A is communicated with the interface T. At this time, the fluid flows into the mechanical energy conversion device 21 (i.e., the turbine device) through the main pipeline 16, and the turbine device is still driven to rotate in the forward direction.
In summary, the reversing controller 24 adjusts the fluid flowing direction in the main pipe 16 by the reversing mechanism 25, regardless of whether the piston 12 moves in the cylinder 11 in the forward direction or in the reverse direction, based on the signal of the fluid flowing direction in the main pipe 16 fed back by the sensor 23, so that the mechanical energy conversion device 21 (turbine device) can always keep the same rotating direction.
In addition, in the present embodiment, in order to further reduce the number of accessories and improve the versatility of the components, the reversing controller 24 and the above-mentioned valve controller may be integrated into a single unit, that is, a general controller, which can control the valve actuator to operate to adjust the opening and closing degree of the main adjustable valve 17 in response to the control signal, and can control the reversing mechanism 25 to operate to adjust the rotation direction of the output shaft of the mechanical energy conversion device 21 in response to the signal of the sensor 23.

The connection mode of the bypass pipeline 26 and the two ends of the cylinder body 11 is the same as the connection mode of the main pipeline 16 and the two ends of the cylinder body 11, or the two ends of the cylinder body 11 are respectively connected with a common pipeline, and the common pipeline is respectively provided with a tee joint, so that the main pipeline 16 and the bypass pipeline 26 can be conveniently connected for use; the bypass adjustable valve 27 is connected and installed on the bypass pipeline 26 in the same way as the main adjustable valve 17 is connected and installed on the main pipeline 16; this embodiment is not described in detail. As shown in fig. 4, the bypass adjusting system in the present embodiment is provided on the basis of the mechanical energy damper 20 (the reversing mechanism 25 is a reversing valve) disclosed in the third embodiment.
In this embodiment, the bypass adjustment system is provided for the purpose of:
1. when the whole set of mechanical energy damper 20 is required to be in the minimum damping state, the bypass adjustable valve 27 in the bypass adjusting system is adjusted to the maximum opening degree, so that the damping in the mechanical energy generating damper A2 is minimum, and the damping size of the mechanical energy damper 20 is reduced as much as possible;
2. when the mechanical energy conversion device 21 in the mechanical energy damper 20 is required to output the mechanical energy, the bypass adjustable valve 27 in the bypass adjusting system is closed, and the flow rate of the fluid is controlled through the main adjustable valve 17 in the adjustable damping system, so that when the fluid flows through the mechanical energy conversion device 21, the mechanical energy can be output outwards through the mechanical energy conversion device 21.

In this embodiment, the mechanical energy conversion device 21 is driven by the fluid in the main pipeline 16 to rotate, and the generator is driven by the transmission shaft to rotate, so as to generate electricity, thereby converting the pressure energy of the fluid in the mechanical energy damper 20 into electric energy for recycling. The direction of rotation of the output shaft of the mechanical energy conversion device 21 is controlled by the selector valve 25 disposed in the mechanical energy damper 20, and the generator 22 can always output a current in one direction.

The difference from the fifth embodiment is that the reversing mechanism 25 may be configured as a wire controller instead of the reversing valve, so as to form the mechanical energy generation damper B3. The wiring controller controls the direction of current output by the power generation system by adjusting the forward and reverse wiring of the power generation device 22 (i.e., the generator). As shown in fig. 7, which is based on fig. 5, the reversing valve is replaced with a wired controller.
When in use:
1. if the piston rod 13 pushes the piston 12 to move forward in the cylinder 11 (i.e., the piston 12 moves to the top chamber side), the fluid in the piston flows into the main pipeline 16, the sensor 23 acquires the flow direction information of the fluid in the main pipeline 16 and feeds the flow direction information back to the commutation controller 24, and the commutation controller 24 controls the wiring direction of the power generation device 22 in the power generation system to be a forward wiring direction through the wire-changing controller; at this time, the fluid flows into the mechanical energy conversion device 21 (i.e. the turbine device) through the main pipeline 16 to drive the mechanical energy conversion device to rotate in the forward direction, the mechanical energy conversion device 21 drives the power generation device 22 (i.e. the generator) to rotate in the forward direction, and the power generation device 22 outputs a forward current;
2. if the piston rod 13 pushes the piston 12 to move forward in the cylinder 11 (i.e. the piston 12 moves to one side of the bottom cavity), the fluid in the piston flows into the main pipeline 16, the sensor 23 acquires the flow direction information of the fluid in the main pipeline 16 and feeds the flow direction information back to the reversing controller 24, and the reversing controller 24 controls the wiring direction of the power generation device 22 in the power generation system to be reverse wiring through the wire-changing controller; at this time, the fluid flows into the mechanical energy conversion device 21 (i.e., the turbine device) through the main pipeline 16 to drive the mechanical energy conversion device 21 to rotate in the reverse direction, the mechanical energy conversion device 21 drives the power generation device 22 (i.e., the generator) to rotate in the reverse direction, and at this time, the power generation device 22 still outputs a forward current.
In summary, the reversing controller 24 can control the wiring direction of the power generator 22 by the wire-changing controller, no matter whether the piston 12 moves in the cylinder 11 in the forward direction or in the reverse direction, according to the signal of the fluid flowing direction in the main pipeline 16 fed back by the sensor 23, that is, the reversing controller 24 can make the power generator 22 output the forward current all the time.

For example, the rotating shafts of the mechanical energy conversion devices 21 may be arranged around the transmission shaft, a driving gear is installed on the rotating shaft of each mechanical energy conversion device 21, and a driven gear is installed on the transmission shaft, so that the rotating shafts of the mechanical energy conversion devices 21 respectively drive the transmission shaft to rotate via one driving gear, and further drive the power generation device 22 to rotate to generate power. Alternatively, the same number of driven gears as the mechanical energy dampers 20 may be arranged on the transmission shaft, so that the driving gear on the rotating shaft of the mechanical energy conversion device 21 in each mechanical energy damper 20 is correspondingly meshed with one driven gear on the transmission shaft.
