Description

Technical Field

[0001] The present invention relates to the technical field of hydropower generation, and in particular to a floating offshore power generation system. Background Art

[0002] In the prior art, a power generation device is placed in water, and the water flow impacts the water wheel, causing it to rotate and generate electricity. However, there are many debris and organisms in the water, which need to be intercepted to avoid affecting the rotation and power generation of the water wheel. The existing interception device has a poor interception effect, resulting in serious damage to the water wheel.

[0003] For example, the authorization announcement number CN109653932B provides a stable floating tube hydropower generation device that prevents drifting debris. Water flows into the cylinder through the water inlet cavity, and is guided by its small end and the guide head as well as the accelerating rifling inside the cylinder to accelerate the water flow, impacting the rotating water wheel. The rotating water wheel rotates rapidly to generate current, which is transmitted by the transmission line. On the horizontal plane, the horizontal water dividing plate increases the contact area between the device and the water, reduces the positive impact force of the water flow on the device, increases the reaction force of the device on the water, and makes the device more stable. The bottom water dividing plate on the vertical plane plays the same role. When some smaller debris and swimming fish pass through the anti-blocking cover and enter the cylinder, the water retaining plate uses the accelerated water flow inside the cylinder to make the swivel have a rotational force. The water retaining block is impacted by water to cause the debris grabbing net to shrink, grab the debris in the water flow and throw the debris out through the movable discharge hole by the rotational force, so as to prevent the rotating water wheel from being entangled or damaged.

[0004] It has major drawbacks: it relies solely on the flow of water to give the swivel a rotational force, and grabs debris entering the water in the water inlet chamber during rotation. When the water flow is unstable, the swivel will stop rotating, resulting in the inability to intercept the debris entering the interior, resulting in poor interception effect. At the same time, when the debris capture component is rotating, the temperature in the water is in a changing state. When the temperature is not reached and the memory soft metal deforms, the memory soft metal outside the debris grabbing net cannot be deformed, making it impossible for the debris grabbing net to fit with the guide head, resulting in gaps, and the interception effect of debris is reduced. Summary of the invention

[0005] The embodiment of the present application provides a floating offshore power generation system, which solves the problem that the existing technology relies solely on the flow of water, so that the swivel has a rotational force, and the debris entering the water in the water inlet chamber is captured during rotation. When the water flow is unstable, the swivel will stop rotating, resulting in the inability to intercept the debris entering the interior, resulting in poor interception effect. At the same time, when the debris capture component rotates, the temperature in the water is in a changing state. When the temperature is not reached, the memory soft metal deforms, and the memory soft metal outside the debris capture net cannot be deformed, so that the debris capture net cannot fit with the guide head, resulting in a gap, and the interception effect of the debris is reduced. It is achieved that the motor provides the filter screen with rotational power, improves the interception effect of smaller debris or small fish in the water, and at the same time changes the fixing method of the interception net. The side of the interception net close to the drainage head is unobstructed. When rotating, the interception net can be deformed and fit with the drainage head to reduce the gap.

[0012] As an improvement, once the motor is started, it drives the interception net to rotate. After the interception net is no longer in contact with the drainage head, the magnet one and the fixed column two repel each other.

[0016] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages: First, the motor provides the filter with rotational power to improve the interception effect of smaller debris or small fish in the water. At the same time, the fixing method of the interception net is changed. The side of the interception net close to the drainage head is unobstructed. When rotating, the interception net can be deformed and fit with the drainage head to reduce the gap. Secondly, when the interception net enters the water inlet cylinder, under the action of magnetic force, the height of the fixed column 2 is lifted, so that it can wrap the intercepted debris and limit the position of the debris. When the interception net rotates to the outside of the water inlet cylinder, the magnetic force disappears, and the interception net is quickly unfolded under the pulling and resetting of the reset rope to clean the debris, thereby improving the cleaning effect. Third, enhanced debris cleaning capability: the vibrating interception net can more effectively capture and fix debris that floats with the water flow, such as fallen leaves, branches, plastic bags, etc., to prevent them from entering and entangled in the water wheel, thereby affecting the normal rotation of the water wheel and the power generation efficiency, ensuring the sustainability of the cleaning effect; fish protection: the vibrating and disturbed water flow can drive nearby fish away from rotating parts that may cause harm to them, thereby reducing the risk of fish being entangled or injured, helping to maintain the balance of aquatic ecosystems and reduce potential threats to fish and other aquatic organisms caused by human activities; improving energy efficiency: cleaning up debris and driving away fish can reduce their obstruction to water flow, allowing more water to smoothly impact the rotating water wheel, thereby improving energy efficiency and helping to improve the power generation efficiency of the device; Fourth, the enhanced debris interception capability, the rotating cleaning component can periodically change its position in the water flow, thereby intercepting debris from different directions and angles. Compared with static interception, this dynamic interception method can more effectively cover a wider water flow area and improve the comprehensiveness and efficiency of debris interception; when there is more debris entering from one side, the rotation of the rotating drum can allow another cleaning component to take over its work, ensuring that the debris in the water flow is always effectively intercepted and reducing omissions; enhanced fish protection effect, the rotating cleaning component will form a dynamic water flow barrier while disrupting the water flow, which has a stronger repelling effect on nearby fish. Compared with static repelling, this dynamic repelling method can alert fish more and keep them away from the device area, further reducing the risk of being involved or injured. At the same time, the rotating protective cover can shake off the intercepted debris to prevent it from entering the water inlet barrel due to long-term impact of the water flow, thereby improving the cleaning effect.

[0022] Embodiment 1: Figure 1-Figure 6 As shown, the present application provides a floating offshore power generation system, including a power generation component 100 and a cleaning component 200; The power generation assembly 100 includes a water inlet cylinder 140, a connecting rod 150 and a drainage head 170; The water inlet cylinder 140 is in the shape of a truncated cone that is continuous along its axis, and the axis of the water inlet cylinder 140 is parallel to the horizontal plane; The drainage head 170 is ellipsoidal, and the axis of the drainage head 170 is on the same straight line as the axis of the water inlet cylinder 140. The drainage head 170 is located in the water inlet cylinder 140, and a gap is left between the drainage head 170 and the water inlet cylinder 140 to form a water flow cavity; One end of the connecting rod 150 is fixed on the drainage head 170, and the end of the connecting rod 150 away from the drainage head 170 is fixed on the inner wall of the water inlet cylinder 140; It also includes a cleaning assembly 200, wherein there are multiple cleaning assemblies 200, and the cleaning assemblies 200 are evenly arranged on the water inlet cylinder 140 in an annular shape; The cleaning assembly 200 includes a through port 210, a fixing plate 1 220, a fixing plate 230, a rotating column 240, a motor 1 250 and a cleaning member; A through opening 210 is formed on the side of the water inlet cylinder 140, and the through opening 210 passes through the inside and outside of the water inlet cylinder 140; The fixing plate 1 220 and the fixing plate 2 230 have the same structure. Both the fixing plate 1 220 and the fixing plate 230 are cylindrical. The fixing plate 1 220 and the fixing plate 230 are symmetrically fixed in the through opening 210. The rotating column 240 is cylindrical, and the axis of the rotating column 240 is on the same straight line as the axis of the fixing plate 1 220. The rotating column 240 is located between the fixing plate 1 220 and the fixing plate 2 230, and the two ends of the rotating column 240 are respectively rotatably connected to the sides of the fixing plate 1 220 and the fixing plate 2 230 that are close to each other; The cleaning member includes a fixing column 1 260, a fixing column 270 and an intercepting net 280; The first fixing column 260 is fixed on one side of the rotating column 240 , and the second fixing column 270 is disposed on one side of the rotating column 240 ; The interception net 280 is fixed between the first fixing column 260 and the second fixing column 270; There are multiple cleaning pieces, which are evenly spaced and arranged on the side wall of the rotating column 240 in a ring shape; The motor 1 250 is fixed to a side of the fixing plate 1 220 away from the rotating column 240, and the output end of the motor 1 250 is fixed to a rotating shaft rotatably connected to the rotating column 240; When the motor 1 250 is started to rotate the rotating column 240, the interception net 280 can intermittently fit the outer wall of the drainage head 170; The motor 1 250 is a waterproof motor, and the rotation axis of the output end of the motor 1 250 is on the same straight line as the axis of the rotating column 240; The length direction of the interception net 280 is parallel to the axis of the rotating column 240; The rotating column 240 and the motor 1 250 are both located outside the water inlet cylinder 140; In the initial state, the fixing column 1 260 is in close contact with the fixing plate 1 220 , and the fixing column 2 270 is in close contact with the fixing plate 2 230 ; The interception net 280 is made of braided nylon rope; When the motor 1 250 drives the rotating column 240 to rotate, the interception net 280 located in the water inlet cylinder 140 rotates in the opposite direction to the water flow direction; The power generation assembly 100 further includes a floating plate 110, a water outlet cylinder 120, a connecting plate 130, a protective cover 160 and power generation blades 180; The water outlet cylinder 120 is in the shape of a truncated cone that is connected along its axis. The axis of the water outlet cylinder 120 is on the same straight line as the axis of the water inlet cylinder 140. The end of the water outlet cylinder 120 with a smaller outer diameter is fixed to the end of the water inlet cylinder 140 with a smaller outer diameter. The water outlet cylinder 120 is connected to the water inlet cylinder 140, and the water flows from the water inlet cylinder 140 to the water outlet cylinder 120. The connecting plate 130 is fixed to the upper side of the water outlet cylinder 120 and the water inlet cylinder 140, and the floating plate 110 is fixed to the upper side of the connecting plate 130; The protective cover 160 is fixed to one end of the water inlet cylinder 140 away from the water outlet cylinder 120; The power generation blade 180 rotates at one end of the drainage head 170 away from the protective cover 160. The drainage head 170 is provided with a generator, and the rotating shaft of the power generation blade 180 is fixed on the transmission shaft of the generator. The power of the motor 250 when working comes from the electricity generated by the generator; The generator is prior art and will not be described in detail here.

[0023] During the power generation process of the device, the floating plate 110 is fixed to one side of a ship or building on the water surface, so that water flows in from the water inlet cylinder 140 and flows out from the water outlet cylinder 120. In this process, the power generation blades 180 are driven to rotate, thereby generating electricity. During the flow of water, the protective cover 160 can intercept larger impurities in the water to prevent them from entering the water inlet cylinder 140 and affecting the rotation of the power generation blades 180. For some smaller debris or small fish, the pneumatic motor 250 is used to drive the rotating column 240 and the interception net 280 to rotate. The interception net 280 located in the water inlet cylinder 140 rotates from the outside to the inside toward the water inlet. During the rotation process, smaller debris or small fish are intercepted in the water flow. When the interception net 280 rotates out of the water inlet cylinder 140, the smaller debris or small fish in the water flow are transported out through the interception net 280.

[0024] Compared with the prior art, when in use, the motor 250 is used to provide rotational power for the filter, thereby improving the interception effect of smaller debris or small fish in the water. At the same time, the fixing method of the interception net 280 is changed, and the side of the interception net 280 close to the drainage head 170 is unobstructed. When rotating, the interception net 280 can be deformed and fit together with the drainage head 170 to reduce the gap.

[0025] Embodiment 2: When the embodiment 1 is in use, after the interception net 280 intercepts smaller debris or small fish, there is no other interception method for the smaller debris or small fish. Since the interception net 280 is always in a rotating state, centrifugal force is generated during the rotation process. When the interception net 280 for intercepting debris has not rotated to the outside of the water inlet cylinder 140, the smaller debris or small fish is thrown out, resulting in interception failure. Based on this, the solution of the embodiment 1 is improved, such as Figure 7-Figure 9 As shown: The cleaning assembly 200 further includes a slide rail 241, a slider 242 and a reset rope 290; The side wall of the rotating column 240 is provided with a slide rail 241, the length direction of the slide rail 241 is parallel to the axis direction of the rotating column 240, the slide rail 241 is slidably connected to the slider 242, and the second fixed column 270 is fixed on the slider 242; The number of the reset ropes 290 is consistent with the number of the second fixing columns 270, and they correspond one to one. One end of the reset rope 290 is fixed to the end of the second fixing column 270 away from the slide rail 241, and the end of the reset rope 290 away from the second fixing column 270 is fixed to the connection between the rotating cylinder 142 and the second fixing plate 230. The reset rope 290 is an elastic rope, and the second fixing column 270 is a magnet; It also includes a magnetic attraction component 400, and the magnetic attraction component 400 includes a magnet 1 410; The magnet 1 410 is fixed on one side of the fixing plate 230 close to the fixing plate 1 220 , and the magnet 1 410 is arc-shaped. The magnet 1 410 is located in the water inlet cylinder 140 ; The magnet 1 410 and the fixing column 270 repel each other at the side close to each other; The magnetic force of the magnet 1 410 close to the protective cover 160 is greater than the magnetic force of the magnet 1 close to the water outlet tube 120. The motor 1 250 is started to drive the interception net 280 to rotate. After the interception net 280 is no longer in contact with the drainage head 170, the magnet 1 410 and the fixing column 270 repel each other.

[0026] During the rotation, when the interception net 280 enters the water inlet cylinder 140, the interception net 280 first contacts and fits with the drainage head 170. After the interception net 280 is no longer in contact with the drainage head 170, the fixed column 270 begins to be repelled by the magnetic force of the magnet 1 410. During the rotation, the magnetic force continues to increase, causing the height of the fixed column 270 to continue to rise, and the opening of the interception net 280 gradually becomes smaller, wrapping the intercepted debris. When the interception net 280 rotates out of the water inlet cylinder 140, the fixed column 270 is quickly reset by the reset rope 290, and the interception net 280 is quickly unfolded to remove the internal debris.

[0027] When the interception net 280 enters the water inlet cylinder 140, under the action of magnetic force, the second fixed column 270 is moved closer to the first fixed column 260, so that it wraps the intercepted debris and limits the position of the debris. When the interception net 280 rotates to the outside of the water inlet cylinder 140, the magnetic force disappears, and the interception net 280 is quickly unfolded under the pulling and resetting of the reset rope 290 to clean the debris and improve the cleaning effect.

[0028] Embodiment 3: When the second embodiment is in use, when the interception net 280 rotates out of the water inlet cylinder 140, the wrapped debris is cleaned by the water flow, but the cleaning effect achieved by the water flow alone is poor, and the wrapped debris cannot be completely cleaned, resulting in the debris being transported back into the water inlet cylinder 140. Based on this, the solution of the second embodiment is improved, such as Fig.10 As shown: The magnetic attraction assembly 400 further includes a second magnet 420, which is fixed to a side of the second fixing plate 230 close to the first fixing plate 220. There are a plurality of second magnets 420, which are evenly spaced. The second magnet 420 and the second fixing column 270 repel each other at the side close to each other; The second magnet 420 is located outside the water inlet cylinder 140 .

[0029] When the intercepting net 280 that has captured the debris rotates out of the water inlet cylinder 140, the fixing column 270 will be intermittently repelled by the plurality of magnets 2 420, and multiple vibrations will be generated in this process, which can clean up the debris firmly attached to the intercepting net 280 and improve the cleaning effect. At the same time, the frequent vibrations can disrupt the surrounding water flow and drive away nearby fish.

[0030] Enhanced debris clearing capability: the vibrating interception net 280 can more effectively capture and fix debris that floats with the water flow, such as fallen leaves, branches, plastic bags, etc., to prevent them from entering and entangled in the water wheel, thereby affecting the normal rotation of the water wheel and the power generation efficiency, ensuring the continuity of the cleaning effect; fish protection: the vibrating and disturbed water flow can drive nearby fish away from rotating parts that may cause harm to them, thereby reducing the risk of fish being entangled or injured, helping to maintain the balance of aquatic ecosystems and reducing potential threats to fish and other aquatic life caused by human activities; improving energy efficiency: clearing away debris and driving away fish can reduce their obstruction to water flow, allowing more water to smoothly impact the rotating water wheel, thereby improving energy efficiency and helping to improve the power generation efficiency of the device.

[0031] Embodiment 4: When the embodiment 3 is in use, the cleaning assembly 200 intercepts the debris in the incoming water flow, but there are gaps between adjacent cleaning assemblies 200, which cannot achieve the interception effect, resulting in a large amount of debris entering through the gaps. Based on this, the solution of the embodiment 3 is improved, such as Figure 1-Figure 2 , Fig.11 As shown: The water inlet cylinder 140 includes a fixed cylinder 141, a rotating cylinder 142, a groove 143 and a block 144; The fixed cylinder 141 and the rotating cylinder 142 are both cylindrical and penetrate along their axes, and the axes of the fixed cylinder 141 and the rotating cylinder 142 are on the same straight line; The fixed cylinder 141 has a groove 143 on one side close to the rotating cylinder 142. The groove 143 is annular and has a trapezoidal cross section. The rotating cylinder 142 has a block 144 on one side close to the fixed cylinder 141. The block 144 is annular and has a trapezoidal cross section that matches the groove 143. The block 144 is slidably connected in the groove 143. One end of the connecting rod 150 away from the drainage head 170 is fixed to the inner wall of the fixed cylinder 141, and the through port 210 is provided on the rotating cylinder 142; Also includes a rotating assembly 300, the rotating assembly 300 includes a motor 2 310, a gear 320 and a gear 330; The gear teeth 330 are fixed to the outer ring of the rotating cylinder 142 and are evenly spaced and distributed in a ring shape; The second motor 310 is fixed to one side of the connecting plate 130, and the gear 320 is fixed to the output end of the second motor 310. The second motor 310 is meshed with the gear 330, and the rotation axis of the second motor 310 is parallel to the axis of the rotating cylinder 142. The second motor 310 is a waterproof motor, and the power of the second motor 310 when working comes from the electricity generated by the generator.

[0032] When the device is placed in water to generate electricity, the motor 2 310 can drive the gear 320 to rotate, and the gear 320 engages with the gear teeth 330 to drive the rotating cylinder 142 to rotate. During the rotation, the position of the cleaning component 200 can be changed, so that the part without the cleaning component 200 installed can also intercept debris, thereby improving the interception effect. At the same time, during rotation, the water flow can be disturbed to drive away nearby fish.

[0033] Enhanced debris interception capability: the rotating cleaning assembly 200 can periodically change its position in the water flow, thereby intercepting debris from different directions and angles. This dynamic interception method can more effectively cover a wider water flow area than static interception, and improve the comprehensiveness and efficiency of debris interception; when there are more debris entering from one side, through the rotation of the rotating cylinder 142, another cleaning assembly 200 can take over its work, ensuring that the debris in the water flow is always effectively intercepted and reduced omissions; enhanced fish protection effect: the rotating cleaning assembly 200 will form a dynamic water flow barrier while disturbing the water flow, which will have a stronger repelling effect on nearby fish. This dynamic repelling method can arouse the vigilance of fish more than static repelling, making them stay away from the device area, further reducing the risk of being involved or injured. At the same time, the rotating protective cover 160 can shake off the intercepted debris to prevent it from entering the water inlet cylinder 140 due to long-term impact of the water flow, thereby improving the cleaning effect.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
