hydraulic pressure master station 4 is including indulging the hydraulic tank who puts, the hydraulic tank internal storage has hydraulic oil, and it has the drain port to open on one side lateral wall of hydraulic pressure oil pocket, and install and supply oil pipe 27, supply oil pipe 27's the other end and the logical liquid mouth that piston biasing mechanism exerted pressure cylinder body to be connected, hydraulic tank sets up in 4 float collection can the unit tops, and through the bolt with under the cylinder body 341 of float collection can the unit together fixed, and the cylinder body 341 of float collection can the unit go up the cavity all with hydraulic tank inside seal intercommunication, its connected mode has the multiple, for example: the bottom of the hydraulic oil tank is provided with oil ports with the same number as the float energy collecting units, and the oil ports are respectively connected with the liquid through ports of the cylinder body 341 corresponding to the float energy collecting units through oil pipes; when the ocean wave energy collecting device is used, the fixed direction of the fixed seat 31 is parallel to the wave crest of the ocean wave, so that when the ocean wave passes through, the wave crest of the ocean wave drives the floats in the four floats on the fixed seat to float upwards along the float frame at the same time, hydraulic oil is injected into the hydraulic oil tank by the piston control mechanisms of the four float energy collecting units, the hydraulic oil tank can synchronously discharge the hydraulic oil into the upper chamber 2612 of the piston pressure applying mechanism pressure applying cylinder body 261 through the oil supply pipe, compared with the embodiment 2, the ocean wave energy captured by the float energy collecting units is collected and transmitted to the piston pressure applying mechanism through the hydraulic oil tank, and therefore the capturing and utilizing efficiency of the ocean wave energy is improved.

Example 4

Embodiment 4 is different from embodiment 3 in that a plurality of sets of energy conversion devices and oscillation energy collection devices are provided, as shown in fig. 11, a plurality of energy conversion devices are provided on an offshore platform or a beach on which a power generation system is installed, a sealed water tank of each energy conversion device is connected to a water storage member, the same number of oscillation energy collection devices as the energy conversion devices are all provided in a sea area near the power generation system, the same number of oscillation energy collection devices as the energy conversion devices are provided in the sea area at intervals in the transverse direction, each oscillation energy collection device is connected to a corresponding energy conversion device, each oscillation energy collection device is provided in the longitudinal direction in parallel to a wave crest, so that when in use, the same wave sequentially drives each oscillation energy collection device from front to back to transfer captured wave energy to the corresponding energy conversion device, so that the same wave operates to inject power generation water into the water storage member, compared with a single-group energy conversion device and an oscillation energy collection device, through the arrangement of the multiple-group energy conversion device and the oscillation energy collection device, water can be replenished into the water storage device for multiple times continuously when a single wave passes through, so that the capture and utilization efficiency of wave energy is further improved, the operation of a power generation system is further ensured, and the stability of the power generation system is enhanced.

Example 5

Embodiment 5 differs from embodiment 4 in that the float holder is fixed obliquely to the holder.

As shown in fig. 12-13, both ends all are articulated with the fixing base about the bottom of float frame surface of a poor water one end, and the top of float frame surface of a poor water one end is articulated with the base of float frame surface of a poor water rear side through telescopic link 5, and the kind of telescopic link 5 has the multiple, for example: the telescopic rod 5 comprises a threaded sleeve 51 in the middle and screws sleeved at two ends of the threaded sleeve, the external threads of the upper screw 52 and the lower screw 52 are arranged in opposite directions, the top end of the upper screw 52 is hinged with the top end of the float frame 32, the bottom end of the lower screw 52 is hinged with the base, and when the threaded sleeve 51 is rotated, the upper screw 52 and the lower screw 52 can simultaneously extend into the threaded sleeve 51 in opposite directions along the threaded sleeve 51 or extend out of the threaded sleeve 51 in opposite directions, so that the whole length of the telescopic rod 5 is adjusted; therefore, when the power generation device is used, the length of the telescopic rod can be adjusted according to the wave amplitude characteristic of sea waves in a sea area where the oscillation energy collecting device is installed, the inclination angle of the float frame is controlled, when the sea waves pass through the float frame, the vertical buoyancy of the sea waves can drive the floats in the float frame to slide to the top end of the float frame along the float frame, hydraulic oil is injected into the pressure cylinder body through the piston control mechanism driven by the push rod 345, and when the vertical buoyancy of the sea waves drives the floats to float, the floats are obliquely arranged, so that the longitudinal impact force of the sea waves can also drive the floats in the float frame to slide along the float frame, the oscillation energy collecting device in the power generation device not only can capture the vertical buoyancy of the sea waves, but also can capture mass longitudinal impact force, so that the floats can be driven to slide to the top end of the float frame along the oblique float frame, compared with the embodiment 4, the energy of the up-and-down reciprocating motion of the wave energy and the energy of the longitudinal impact of the wave energy are fully converted into the water potential energy required by the power generation system, and the efficiency of the floater for capturing the wave energy is improved.

Example 6

The difference between the embodiment 6 and the embodiment 5 is that, as shown in fig. 14, a mounting hole penetrating through the lowermost float is formed downwards in the middle of the uppermost float in the float frame 32, a sliding sleeve 7 is fixedly sleeved in the mounting hole, a sliding rod 8 is sleeved in the sliding sleeve, the tail end of the sliding rod extends downwards out of the sliding sleeve and is vertically fixed on the lower fixing plate at the bottom of the float frame, when the float slides up and down along the float frame, the float can slide up and down along the sliding rod, and when the float is driven to slide along the inclined float frame to the top end of the float frame by the vertical buoyancy of the sea waves and the longitudinal granule force, the friction between the float and the float frame can be reduced due to the limitation of the sliding sleeve and the sliding rod.
