Description

Single-gear-ring double-rotation-driven wave energy collecting device

Technical Field

The invention belongs to the field of green renewable energy sources for wave energy utilization, and particularly relates to a single-gear-ring double-rotation-driven wave energy collecting device.

Background

The wave energy refers to the energy of water surface waves, has wide distribution range in oceans, lakes and reservoirs, high energy density and easy large-scale utilization, and is a typical clean pollution-free green renewable energy source which is rapidly developed. China is a big ocean country, ocean energy resources are rich, and development prospects are wide. Many islands in China are basically supplied with power without a power grid, the production and the life of residents on the islands are relatively backward, and the economic development of the residents is restricted by the difficulty of power supply; particularly, offshore working platforms and islands of west sand and south sand far away from continents have more urgent requirements on electric power, so that research and development of wave energy devices suitable for oceans in China have practical significance and economic value.

The types of the current wave energy collecting devices are mainly as follows: wave-collecting submersible pressure difference type, wave attenuation type, water column oscillation type, surge oscillation type, nodding duck type, over-top type, eagle type, raft type and the like. The wave energy collection method can be roughly divided into four types: clutch gear box, hydraulic, pneumatic and direct drive, but basically all are monomers to collect wave energy. In recent years, a direct drive type conversion system that directly converts wave energy into electric energy using a linear conversion motor has been vigorously developed.

Waves are three-dimensional in space, random in time, and inconstant in frequency, phase, amplitude, and direction. These characteristics have a great negative effect on the collection of wave energy, making the design of the solitary wave energy collection device extremely complex and the collected wave energy also very unstable. The existing various wave energy collecting devices are mainly developed by monomer devices, and the adverse effects of the three-dimensional property, randomness and inconstant property of waves on wave energy collection are reduced.

The applicant's granted utility model patent (ZL 2018214635225) proposed a wave energy collecting device (hereinafter referred to as "applied patent").

The core concept of the applied patent publication is: the wave energy collecting device fully utilizes the three-dimensional property, randomness and inconstant of waves, each wave energy collecting component independently runs, the main shaft is driven to rotate along the consistent direction through the ratchet wheel, stable mechanical energy is obtained after the wave energy collecting device is converged by the transmission shaft, and wave energy collection is achieved.

The technical scheme of the applied patent comprises the following steps: the system comprises a working platform, N wave energy collecting systems, a transmission device, a speed regulating device and an energy conversion system; the wave energy collecting systems respectively comprise a horizontal main shaft and M vertical sliding rails which are arranged in parallel and are respectively arranged on a frame, and each sliding rail is respectively provided with a wave energy collecting component.

The key structure body of the applied patent is a wave energy collecting component, and the key point of realization is that a large-scale working platform and a plurality of frames for erecting slide rails are needed. The wave energy collecting component slides up and down along the slide rail, and is suspended and supported by a single connecting rod when the floating ball is positioned at the lowest end of the wave trough. Under the action of the transverse thrust of waves, the floating ball is supported by a cantilever constrained by one end and is easy to damage or even break. When the wave energy collecting component rises, the rack is meshed with the ratchet wheel to rotate forwards to do work, and when the wave energy collecting component falls, the ratchet wheel rotates reversely to do no work, so that the wave energy collecting component belongs to single-gear driven one-way work.

Each turret mounting member C5 is coupled to a respective one of the turrets D, and the turret D and turret shaft C5C are freely rotatable relative to the first mount C5a and the second mount C5 b.

The structures of the rotating frames D are the same, fig. 5 (a) and (b) are respectively schematic structural diagrams of 1 rotating frame D on the right side in fig. 1, the rotating frame D comprises a main rotating frame, an arc-shaped single-toothed ring D1 and a floating ball mounting plate D7, the main rotating frame is respectively fixed at the head end and the tail end of the main rotating frame, the middle part of the main rotating frame is sleeved on a rotating frame shaft C5C, and the axial movement of the rotating frame D along the rotating frame shaft C5C is limited by a first mounting seat C5a and two second mounting seats C5 b; the arc-shaped single-toothed ring D1 is engaged with the outer toothed ring C4h of the main ratchet C4b in the corresponding one of the drive members C4. The main frame of the rotating frame comprises a middle main body and diagonal brace rod assemblies symmetrically positioned at two sides of the middle main body; the middle body comprises a central plate D0, a plurality of rod pieces D2 and a vertical plate D6 which are fixedly connected, wherein a central hole D4 (namely the circle center of an arc-shaped single-tooth ring D1) on the central plate D0 is sleeved on a rotating frame shaft C5C, so that the rotating frame D and the rotating frame shaft C5C are enabled to freely rotate under the support of a first mounting seat C5a and two second mounting seats C5b and cannot move along the axial direction of the rotating frame shaft C5C; the floating ball mounting plate D7 is fixed on the lower plane of the vertical plate D6. The middle body and the arc-shaped single-tooth ring D1 form a coplanar hyperstatic structure to bear acting forces in the horizontal direction x and the vertical direction y. The inclined strut assembly of the rotating frame D comprises a plurality of first inclined struts D3 and a plurality of second inclined struts D5 which are symmetrically arranged at two sides of the main frame and are similar to a shuttle shape on a horizontal plane; the left end of each first inclined strut D3 is fixedly welded with the single-tooth ring D1, and the right end of each first inclined strut D3 is fixedly sleeved on a central shaft C5C of the rotating frame at the position of a second mounting seat C5 b; the left ends of a plurality of second inclined supporting rods D5 are also fixedly sleeved at the position of a second mounting seat C5b of the central shaft C5C of the rotating frame, and the right ends are fixedly connected with a floating ball mounting plate D7; each inclined strut can bear the acting force in the direction (z direction) perpendicular to the plane of the main frame of the rotating frame. The three-dimensional rotating frame D formed by the middle main body and the inclined strut assembly can keep stable operation under the action of forces in different directions.

The floating ball mounting plate D7 is located at the lower part of the tail end of the rotating frame D, and the lower part of the floating ball mounting plate D7 is fixedly connected with a corresponding floating ball E through a plurality of fixed connecting columns.

The arc-shaped single-toothed ring D1 of each rotary frame D is engaged with the outer toothed ring C4h of the main ratchet C4b of a corresponding one of the driving members C4 to transmit the wave action force applied to the float ball E to the power shaft C3.

Referring to fig. 3 and 6, the principle that the rotating frame D enables the double ratchets (C4b and C4C) in the driving wheel member C4 to do work when the floating ball E ascends or descends is described by taking the wave energy collecting member on the right side of fig. 1 as an example:

the main ratchet C4b and the auxiliary ratchet C4C are set to have the same structure, the direction of the pawl C4k is consistent, and the inner ratchet ring C4j is matched with the power shaft C3 in a key way. Viewing direction taking fig. 6 as an example, the rotation direction is determined facing the main ratchet C4 b; the outer toothed ring C4h of the two ratchet wheels is engaged with the pawl C4k when rotating clockwise, and the power shaft C3 is driven to rotate clockwise to output force. When the outer toothed rings C4h of the two ratchets rotate anticlockwise, the two ratchets idle and are independent of the rotation of the power shaft C3. When the floating ball E rises, the single-toothed ring D1 rotates anticlockwise around the rotating frame shaft C5C → the outer toothed ring C4h of the main ratchet wheel rotates clockwise (see the arrow direction in figure 6), the clamping pawl C4k drives the power shaft C3 to rotate clockwise to do work → drives the main steering wheel C4D to rotate anticlockwise → enables the auxiliary steering wheel C4E to rotate clockwise → drives the auxiliary ratchet wheel C4C to idle in the anticlockwise direction. When the floating ball E descends, the outer gear ring C4h of the main ratchet wheel idles anticlockwise, and the auxiliary ratchet wheel C4C rotates clockwise to do work. In the mode, the single-tooth ring D1 of the rotating frame D realizes the outer ring reverse linkage of the main ratchet wheel and the auxiliary ratchet wheel through the steering wheels C4D and C4E, and the floating ball E can do work when rising or falling.

A suspension holder C4f (see fig. 1 and 3) rotatable about a suspension holder shaft C4g is provided on an upper portion of the mounting seat C4 a. When the wave energy collecting member needs to be overhauled or stops running when meeting an extreme sea condition, the floating ball end of the wave energy collecting member is lifted, the upper end of the single-tooth ring D1 is lower than the suspension frame shaft C4g, the free end of the suspension frame C4f is turned to the single-tooth ring D1 and sleeved on the upper end of the single-tooth ring, and the floating ball E is separated from the water surface to ensure the safety of the wave energy collecting member. The free end of the suspension C4f is on the right as in FIG. 1, and the upper parts of the two single-toothed rings D1 of the wave energy collecting members on the right are clamped to be in a stop state; the free ends of the suspension frames C4f of the two wave energy collecting members on the left side are rightwards, and normal operation can be kept.

Fig. 7 is a schematic diagram of the floating ball E doing work in the manner of a rotational moment. The floating ball E rotates around the rotating frame shaft C5C under the action of wave fluctuation, and the torque generated by the rotating motion drives the ratchet wheel to rotate and do work. The whole device is positioned in a single-point anchoring mode, the device can be automatically adjusted to the dominant wave direction, the floating ball E mainly bears the acting force Fx in the horizontal direction (x direction) and the acting force Fy in the vertical direction (y direction), and the two acting forces generate moment by the moment arms Lx and Ly which are far away from the center of the rotating frame shaft C5C to do work. As regards possible instantaneous transverse (z-direction) forces, they are balanced by the diagonal braces D3 and D5 of the turret D.

A power shaft output wheel C1 fixedly arranged on a power shaft C3 stably and uniformly outputs the energy of the wave energy collecting unit in a form of rotating mechanical energy for effective utilization of energy utilization devices (such as a generator, a seawater purifying device and the like). Embodiments of the energy-utilizing apparatus are not within the technical scope of the present application.

A plurality of wave energy collecting units are arranged end to end, a bottom floating body A, a middle frame B and an upper platform C are respectively butted through connecting pieces, power shafts C3 of all the units are connected through couplers to form combined units which are connected in series, and stable and uniform rotating mechanical energy is output through one power shaft output wheel C1. The space frame structure formed by welding a plurality of rod pieces P is adopted to connect the serially connected combined units in parallel, and the energy of the power shaft output wheel C1 is converged into consistent rotary mechanical energy through a transmission device (such as a chain, a belt, a gear, a connecting rod and the like). Fig. 8 is a schematic diagram of a combination of 4 wave energy collecting units. Firstly, 4 wave energy collecting units P1 and P2, P3 and P4 are respectively connected in series end to end, and then two groups of devices connected in series are connected in parallel to form a four-way connection of 4X4 wave energy collecting device basic units. A plurality of wave energy collecting device basic units can be combined into an integral device with different scales in a building block mode, when the combined wave energy collecting device basic units are enough, the integral device can be ensured to only ascend and descend along with tide or mean water level and not to jolt along with waves, namely the integral device is relatively stable, and a single wave energy collecting component is ensured to fully utilize three-dimensional, random and inconstant natural attributes of the waves to collect the energy of the waves. According to the conditions of developing water areas, a plurality of sets of integral devices can be arranged to operate in a networking mode.
