Detailed implementation manners

[0023] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] In order to solve the technical problem in the prior art that due to the frequent change of the seawater flow direction, the impeller cannot always face directly, resulting in a long standby time of the impeller and low power generation efficiency, the present invention provides a floating cross double-paddle shaftless rim tidal generator, which can ensure that the power generation assembly in at least one of the installation channels works to generate electricity, and realizes the utilization of tidal energy at all angles by using tidal energy in different directions, thereby improving the power generation efficiency.

[0025] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of a floating cross double-paddle shaftless rim tidal generator in an embodiment of the present invention.

[0026] The present invention provides a floating cross double - propeller shaftless rim tidal generator, which includes a floating body 1, a base body 2 and a power generation assembly 3; the base body 2 is arranged on the floating body 1, and a plurality of installation channels 21 extending in the horizontal direction are arranged on the side surface of the base body 2, and the plurality of installation channels 21 are arranged along the circumferential direction of the base body 2; and the power generation assembly 3 includes a stator 31, a rotor 32 and a turbine 33. The stator 31 is arranged in a ring shape and installed in the installation channel 21, the turbine 33 is rotationally installed in the installation channel 21 along the circumferential direction of the installation channel 21, and the rotor 32 is arranged on the turbine 33 and located inside the rotor 32, so as to drive the rotor 32 to rotate through the turbine 33.

[0027] In this embodiment, please refer to Figures 1 to 3 , the floating body 1 floats on the sea surface, the base body 2 is installed on the floating body 1, and a plurality of installation channels 21 are arranged on the side surface of the base body 2. Each installation channel 21 is provided with a power generation assembly 3. Specifically, when in use, seawater flows into the installation channel 21 and drives the turbine 33 to rotate, thereby driving the rotor 32 to rotate. The relative movement between the rotor 32 and the stator 31 cuts the magnetic induction lines to generate current for power generation. Since the plurality of installation channels 21 are distributed on the circumference of the base body 2, at least one installation channel 21 can be directly facing the seawater flow direction. No matter how the seawater flow direction changes, it can ensure that the power generation assembly 3 in at least one installation channel 21 works for power generation. By utilizing tidal energy in different directions, all - angle tidal energy utilization is realized, and the power generation efficiency is improved.

[0028] Furthermore, the specific number of the installation channels 21 is not limited. Hereinafter, it is described by taking three installation channels 21 as an example.

[0029] Specifically, one end of the installation channel 21 is located on the circumferential side surface of the base body 2, and the other end of the installation channel 21 extends to the central area of the base body 2, that is, the installation channel 21 generally extends along the radial direction of the base body 2.

[0030] In this embodiment, please refer to Figures 1 to 3 , in order to be able to utilize tidal energy in different directions and further improve the utilization rate of tidal energy, the base body 2 is rotationally installed on the floating body 1 along the axis in the vertical direction. With such a setting, the base body 2 can rotate relative to the floating body 1 under the action of seawater, so as to adjust the angle of the installation channel 21, so that one of the installation channels 21 is directly facing the seawater flow direction to improve the power generation efficiency.

[0031] In this embodiment, please refer to Figures 1 to 2, the floating body 1 includes a first floating body 11 and a second floating body 12. The first floating body 11 and the second floating body 12 are arranged at intervals in the vertical direction. The seat body 2 is located between the first floating body 11 and the second floating body 12. The upper and lower ends of the seat body 2 are respectively rotatably installed on the first floating body 11 and the second floating body 12.

[0032] Specifically, both the first floating body 11 and the second floating body 12 are cylindrically arranged, and a cavity is provided inside. The cavity is filled with epoxy resin foam, which is beneficial to floating on the sea surface. The first floating body 11 and the second floating body 12 are arranged at intervals from top to bottom. The upper end of the seat body 2 is rotatably installed on the first floating body 11 through a bearing, and the lower end of the seat body 2 is rotatably installed on the second floating body 12 through a bearing. By providing the first floating body 11 and the second floating body 12, it is beneficial to ensure that the seat body 2 and the power generation assembly 3 float on the sea surface.

[0033] Furthermore, a gravity-like anchor is provided below the second floating body 12 and weighted by a catenary structure. Such a setting has strong adaptability, can better adapt to complex situations, maintain a stable posture during water flow dynamics, reduce the drag risk caused by water flow, and the shape of the catenary helps to naturally distribute the tension on the chain, making the whole system more stable; the weight can be customized in different sea areas to control the height of the equipment to keep a certain height from the sea surface.

[0034] Furthermore, four gravity-like anchors are connected below the second floating body 12 by iron chains. The four gravity-like anchors are evenly distributed by catenaries, and the included angle between adjacent two gravity-like anchors is 90°. The ends of the catenaries of three of the gravity-like anchors are connected with counterweight cylinders to provide stable anchoring force; the remaining one gravity-like anchor is composed of an output cable covered by an armored cable. One end of the output cable is connected to the stator 31, and the other end of the output cable is connected to the submarine cable.

[0035] Furthermore, an electric slip ring is also provided between the seat body 2 and the second floating body 12. The output cable is electrically connected to the stator 31 through the electric slip ring. When the seat body 2 rotates under the impact of water flow, the outer ring of the electric slip ring rotates accordingly, while the inner ring remains stationary, realizing the transmission of electricity and solving the problem that the wire will knot during rotation.

[0036] Furthermore, the electric slip ring is gold-plated to increase conductivity and have good anti-corrosion performance at the same time.

[0037] In this embodiment, please refer to Figure 4 , two sequentially connected flow guiding surfaces 23 are formed on the outer periphery of the seat body 2 between adjacent two installation channels 21. The two flow guiding surfaces 23 are away from each other in the direction towards the middle of the seat body 2.

[0038] Specifically, the seat body 2 is generally arranged in a triangular prism shape. The three installation channels 21 are respectively located in the middle of the three side faces of the seat body 2. The conical surfaces between two adjacent installation channels 21 form two diversion surfaces 23. By providing the diversion surfaces 23, on the one hand, it serves the purpose of guiding the flow of seawater, and on the other hand, when the seawater acts on the diversion surfaces 23, it can push the seat body 2 to rotate, so that the installation channels 21 located in the middle of the side faces are aligned with the seawater flow direction.

[0039] In this embodiment, please refer to Figure 4 and Figure 6 , in order to provide a greater rotational force, a plurality of diversion plates 4 are further provided on the diversion surfaces 23. The plurality of diversion plates 4 are arranged at intervals in the horizontal direction. One end of each diversion plate 4 is rotatably installed on the diversion surface 23 along the axis in the vertical direction.

[0040] Specifically, please refer to Figure 7 , the plurality of diversion plates 4 are evenly arranged at intervals on the diversion surface 23. One end of each diversion plate 4 is rotatably installed on the diversion surface 23 to have a first state of rotating towards the direction close to the diversion surface 23 and a second state of rotating away from the diversion surface 23 and being perpendicular to the diversion surface 23. In the first state, the other end of the diversion plate 4 is close to its adjacent installation channel 21. When the water flow corresponds to the diversion surface 23, under the action of the water flow, the diversion plate 4 is in the second state. At this time, the water flow impacts the diversion plate 4, thereby driving the seat body 2 to rotate, so that one of the installation channels 21 faces the water flow direction to utilize the maximum tidal energy. When the included angle between the water flow and the diversion surface 23 is an acute angle, under the action of the water flow, the diversion plate 4 is in the first state. At this time, the diversion plate 4 fits the diversion surface 23 as much as possible to avoid obstructing the water flow and ensure that the water flow enters the installation channel 21. And arranging a plurality of diversion plates 4 at intervals increases the area of the diversion surface 23 and can generate more rotational force.

[0041] Further, the flow guiding surface 23 is provided with a plurality of grooves, and the plurality of grooves correspond to the plurality of flow guiding plates 4 one by one. A rotating shaft hole is provided in the groove. One end of the flow guiding plate 4 is provided with a mounting portion 411, and the end of the mounting portion 411 is arc-shaped. Rotating shafts 413 are provided on opposite sides of the mounting portion 411. The rotating shafts 413 are coaxially arranged with the end of the mounting portion 411. One side of the mounting portion 411 close to its adjacent mounting channel 21 is provided with an avoidance groove 412. The mounting portion 411 is located in the groove, and the rotating shaft 413 is rotatably mounted in the rotating shaft hole. When in the second state, the side of the mounting portion 411 facing away from its adjacent mounting channel 21 abuts against the side wall of the groove for limiting, thereby restricting the further rotation of the flow guiding plate 4. By providing the avoidance groove 412, it can ensure that the flow guiding plate 4 rotates to the first state, avoiding interference with the groove.

[0042] In this embodiment, please refer to Figures 6 to 7 , in order to further improve the utilization rate, the flow guiding plate 4 includes two first flow guiding plates 41 and a second flow guiding plate 42. One end of the first flow guiding plate 41 is rotatably mounted on the flow guiding surface 23. The two first flow guiding plates 41 are arranged at intervals in the vertical direction. The two first flow guiding plates 41 are spaced apart from each other in the direction facing the adjacent mounting channel 21. The second flow guiding plate 42 is located between the two first flow guiding plates 41. One end of the second flow guiding plate 42 is rotatably mounted on the flow guiding surface 23. The second flow guiding plate 42 is arc-shaped. The two first flow guiding plates 41 and the second flow guiding plate 42 form a V-shaped structure, which can increase the area of the entire flow guiding plate 4 and improve the utilization rate.

[0043] In this embodiment, please refer to Figure 3 , a separating member is provided at one end of the mounting channel 21 to divide the hole at one end of the mounting channel 21 into two mounting holes 22. A power generation assembly 3 is provided in each mounting hole 22. The axes of the two mounting holes 22 intersect outside the seat body 2.

[0044] Specifically, the mounting channel 21 has a special-shaped structure. The separating member is provided at one end of the mounting channel 21, so as to divide one end of the mounting channel 21 into two circular mounting holes 22. The stator 31 is installed in the mounting hole 22, and the turbine 33 is rotatably mounted in the mounting hole 22. And the axes of the two mounting holes 22 intersect outside the seat body 2, that is, the axes of the two turbines 33 intersect outside the seat body 2, forming a cross structure which increases the rotation efficiency under the same flow rate and velocity, thereby further improving the utilization rate of energy.

[0045] In this embodiment, please refer to Figure 5, the turbine 33 includes a rim 331 and a plurality of blades 332. The rim 331 is adapted to the mounting hole 22, and the rim 331 is rotatably mounted in the mounting hole 22. The rotor 32 is sleeved on the outer periphery of the rim 331, and the plurality of blades 332 are circumferentially spaced and arranged within the rim 331.

[0046] Specifically, the rim 331 is rotatably mounted in the mounting hole 22 through a bearing. The rotor 32 is annularly arranged, and the rotor 32 is mounted on the outer periphery of the rim 331 and corresponds to the stator 31. The plurality of blades 332 are evenly arranged within the rim 331, and the blades 332 are inclined. By providing the shaftless rim 331, the energy loss of the traditional shaft generator can be reduced, and the energy utilization rate can be improved.

[0047] Furthermore, the rotor 32 is a permanent magnet, the stator 31 is a coil winding, the stator 31 uses an amorphous alloy stator core, and the rotor 32 uses neodymium iron boron permanent magnet material, which has higher efficiency, smaller volume, lower maintenance cost and better environmental adaptability.

[0048] Further, a plurality of protruding scales are provided on the suction surface of the blade 332, and the plurality of scales form reinforcing ribs. By providing the scales, the contact area between the suction surface of the blade 332 and the fluid can be effectively reduced, the fluid resistance during operation can be reduced, the efficiency of the blade 332 and the energy conversion efficiency can be improved, and the reinforcing ribs improve the operating stability and seismic resistance of the blade 332.

[0049] Further, the blade 332 is a symmetrically twisted blade 332, which can adapt to different water depths and flow velocities. The blade 332 is made of corrosion-resistant titanium alloy material to avoid seawater corrosion and biological attachment.

[0050] In this embodiment, the plurality of installation channels 21 are communicated with each other.

[0051] Specifically, there are three installation channels 21, and one end of the three installation channels 21 is communicated through a tee.

The temperature sensor is arranged on the seat body 2, and the pressure sensor is arranged on the floating body 1.

[0053] Specifically, the rotational speed sensor can calculate the speed, flow rate, and power generation of the turbine 33. The temperature sensor can detect the ambient temperature in real time.
