[0022] To address the technical challenges posed by the high sediment content of tidal currents, which easily generate sludge and marine organisms, thus affecting the efficiency of tidal power generation, such as... Figures 1-7 As shown, the following preferred technical solutions are provided: A water wheel type power generation device, comprising a mounting frame 1 and a fixed seat 2 fixed in the middle of the mounting frame 1, a rotating inner ring 3 is rotatably installed in the middle of the inner side of the fixed seat 2, and a plurality of water wheel blades 4 are installed on the inner side of the rotating inner ring 3, the fixed seat 2 is provided with a stator coil part of the existing water wheel generator principle, and the rotating inner ring 3 is provided with a rotor part of the existing water wheel generator principle, and the rotating inner ring 3 and the fixed seat 2 are rotatably sealed, in use, the mounting frame 1 and the fixed seat 2 are arranged in the strong underwater current, when the tidal current generated by the rising tide, falling tide or stable wave flows through the water wheel blades 4 of the device, the water wheel blades 4 and the rotating inner ring 3 are pushed to rotate, and the mechanical energy is converted into electrical energy by electromagnetic induction principle, the specific power generation principle of the prior art is not described in the case, one side of the mounting frame 1 is connected with a transmission cable 70, the transmission cable 70 is electrically connected with the output end of the power generation part in the fixed seat 2, after the device uses the tidal energy of the ocean to generate electricity, the transmission cable 70 can be used to transmit and use the electrical energy.

[0023] As shown in Figures 3-5 The end of the water wheel blade 4 close to the rotating inner ring 3 is fixed with a rotating shaft two 10, and the inside of the rotating shaft two 10 is provided with a wire 80, the water wheel blade 4 can rotate with the rotating inner ring 3 through the rotating shaft two 10, and the rotating shaft two 10 and the rotating inner ring 3 are sealingly arranged, and the rotating shaft two 10 is hollow, the wire 80 extends from the rotating shaft two 10 to the inside of the water wheel blade 4, the wire 80 includes a conductive wire and a signal transmission line, and the wire 80 is connected with the transmission cable 70 for transmission, and is connected with the control equipment of the power output end on the shore, can supply power to the power consumption part in the water wheel blade 4, and transmit control signal, and the control equipment of the existing power output end is not shown in the case, the inner side of the water wheel blade 4 is provided with an inner cavity 20, the two sides of the inner cavity 20 towards the front and back surfaces of the blade are planar, and the existing device for utilizing the tidal energy of the ocean to generate electricity is often relatively large, so the water wheel blade 4 and the inner cavity 20 are also relatively large.

[0024] Two sides of the inner cavity 20 are provided with linear slide rail one 6, and the linear slide rail one 6 is provided with linear slide rail two 7 above and slidingly, and the linear slide rail two 7 is provided with sliding block 8 slidingly, the linear slide rail one 6 and the linear slide rail two 7 are existing linear electric slide rails, and the linear slide rail one 6, the linear slide rail two 7 and the sliding block 8 constitute an existing principle XY linear module, so that the linear slide rail one 6 and the linear slide rail two 7 can drive the sliding block 8 to move in the plane in the inner cavity 20, the front and back surfaces of the sliding block 8 are respectively provided with two groups of mounting mechanisms 9, and the two groups of mounting mechanisms 9 are respectively provided with stress sensors 30, vibration transducers 40 and vibration sensors 50 from right to left, the linear slide rail one 6, the linear slide rail two 7, the stress sensors 30, the vibration transducers 40 and the vibration sensors 50 are all powered by the wire 80, and are all controlled by the control equipment of the power output end, and the two groups of stress sensors 30, vibration transducers 40 and vibration sensors 50 arranged in front and back are respectively attached to the front and back surfaces of the inner cavity 20, and the attachment surfaces of the stress sensors 30, the vibration transducers 40 and the vibration sensors 50 are all made of wear-resistant metal material, the specific principles of the stress sensors 30, the vibration transducers 40 and the vibration sensors 50 of the prior art are not described again in this case, because the tidal current contains a high content of sand, and the shellfish and algae of marine organisms are easy to adhere to the surface of the water turbine blade 4, forming a composite dirt of silt and biological membrane, which increases the water flow resistance of the water turbine blade 4 and reduces the energy capture efficiency, thereby affecting the efficiency of tidal current power generation, and the water flow speed changes greatly when the tide rises and falls, and the water turbine blade 4 bears periodic impact load for a long time, which is easy to cause local stress concentration of the blade and further cause cracks, thereby reducing the service life of the power generation device and increasing the trouble and cost of regular maintenance of the device in the sea.

[0025] At this time, the stress sensor 30, the vibration transducer 40 and the vibration sensor 50 are driven to move along the inner surface of the water wheel blade 4 synchronously by the driving action of the linear slide one 6 and the linear slide two 7. During the movement, the stress sensor 30 captures the complex dirt state formed by the attachment of silt and the breeding of organisms on the surface of the water wheel blade 4 under the marine tide environment in real time. When the stress threshold of the dirt thickness is detected to be too large, the control device locks the current position. The vibration sensor 50 is used to detect the vibration frequency of the water wheel blade 4 first, and then the high-frequency vibration transducer 40 is started to generate a fixed-point high-frequency vibration. The vibration frequency is avoided to be the same as the vibration frequency of the water wheel blade 4 to avoid resonance. The ultrasonic wave of the vibration transducer 40 is used to destroy the binding force between the dirt and the marine organisms and the surface of the blade under the tide, so as to complete the targeted descaling. At the same time, the stress sensor 30 synchronously collects the stress data of each area of the blade under the periodic impact of the tidal flow. If the stress concentration of the blade itself is detected, the high-frequency micro-vibration is released by the moving vibration transducer 40 to release the local residual stress, so as to avoid the stress accumulation to cause fatigue damage. At the same time, the vibration frequency is avoided to be the same as the vibration frequency of the water wheel blade 4 to avoid resonance. Therefore, it is beneficial to reduce the trouble of stopping the tide energy device blade descaling and relying on manual underwater operation, realize the non-stop automatic precise descaling, protect the water dynamic shape of the blade, improve the tide energy capture efficiency and stabilize the power generation capacity, and reduce the risk of blade cracking and breaking caused by the periodic strong impact of the tide, prolong the service life of the water wheel blade 4, and meet the application requirements of the tide energy large-scale and large-scale power station.

[0026] As shown in Figure 1 , Figure 3 and Figure 9 , the center seat 5 is installed on the axis of the fixed seat 2, and the water wheel blade 4 is rotationally connected with the center seat 5. When the stress sensor 30 detects that the local stress of the blade is excessive due to the impact of the tidal flow, the control device triggers the angle adjusting mechanism of the center seat 5 to quickly adjust the incidence angle of the water wheel blade 4, so as to reduce the impact stress area of the blade and the tidal flow. At the same time, the adjustment position of the water wheel blade 4 and the center seat 5 is sealed to effectively isolate the high-salinity seawater and impurities in the tidal environment. Through the automatic linkage of the detected angle adjustment, the further pulling and impact of the excessive stress on the blade cracking are reduced from the source, the blade damage speed is significantly slowed down, the safety and service life of the blade under the periodic strong impact of the tide are greatly improved, the tide energy generation interruption caused by the blade hidden danger treatment is avoided, and the safety protection and power generation continuity are considered. At the same time, when the stress sensor 30 detects that the stress threshold of the dirt thickness is too large, the incidence angle of the water wheel blade 4 can also be adjusted by using the angle adjusting mechanism of the center seat 5, so that the incidence angle is increased to increase the impact area and impact force of the tidal flow on the blade. The high-frequency vibration of the vibration transducer 40 is used to make the dirt on the surface of the blade be removed better.

[0027] To address the technical challenge of blades being subjected to long-term periodic impacts or collisions from gravel and other particles in tidal currents, which can cause surface indentation and obstruct or even damage to internal detection components, such as... Figures 2-8 As shown, the following preferred technical solutions are provided: The rotating inner ring 3 includes a water turbine shaft 31 rotatably mounted on the fixed base 2. The water turbine shaft 31 rotates in a sealed manner with the fixed base 2, and is connected to the water turbine blades 4. A rotor for power generation is mounted on the water turbine shaft 31, while a stator for power generation is located inside the annular fixed base 2. Under the action of tidal currents, the water turbine blades 4 and the water turbine shaft 31 rotate on the fixed base 2 to generate electricity. A rotating ring 33 is fixed to the outer side of the water turbine shaft 31, and a stationary ring 32 is mounted outside the rotating ring 33 and fixed inside the fixed base 2. The output end of the rotating ring 33 is electrically connected to a wire 80, which is only mounted on the water turbine. Within the blades 4 and the center seat 5, the stationary ring 32 is sealed within the fixed seat 2, while the rotating ring 33 is sealed within the turbine shaft 31. The stationary ring 32 and the rotating ring 33 are located on one side of the stator and rotor for power generation within the turbine shaft 31 and the fixed seat 2. The stator and rotor of the existing principle are not shown in the diagram. The rotating ring 33 can rotate with the turbine shaft 31, and the stationary ring 32 and the rotating ring 33 constitute a conductive slip ring of the existing principle. This allows the stationary ring 32 and the rotating ring 33 to transmit external power to the rotating turbine blades 4 using the wire 80. This makes the conductive slip ring adaptable to the operating conditions of tidal power generation.

[0028] A set of vision sensors 60 is fixedly installed on each of the left and right sides of the mounting mechanism 9. The vision sensors 60 are 180-degree wide-angle industrial cameras that can detect the movement path of the mounting mechanism 9 in all directions. The mounting mechanism 9 includes a mounting base 91 fixed to the sliding block 8. The mounting base 91 has three sets of mounting seats 91 arranged in front of and behind the sliding block 8. At the same time, stress sensors 30, vibration transducers 40 and vibration sensors 50 are installed sequentially on every three sets of mounting seats 91 in front and behind, so as to complete the detection and vibration processing of the front and back of the water turbine blade 4. By using the linear slide rail 1 6 and linear slide rail 2 7 to drive the sliding block 8, the stress sensors 30, vibration transducers 40 and vibration sensors 50 can move in contact with the inner surface of the inner cavity 20 to perform moving scanning detection and vibration processing of the water turbine blade 4. Using the two existing wide-angle vision sensors 60, the inner surface of the inner cavity 20 can be identified on the path when moving in all directions. The specific principle of the existing vision sensors 60 will not be described in detail in this case.

[0029] The inside of each group of mounting seat 91 is provided with filling cavity one 92, and the inside of each group of filling cavity one 92 is rotatably provided with rotating ball seat 93, and the rotating ball seat 93 and the mounting seat 91 are sealed, which can prevent the magnetorheological fluid from leaking from the rotating part of the rotating ball seat 93, and the outer surface of each group of rotating ball seat 93 is fixed with arc-shaped clamping block 94, and in the initial state of the rotating ball seat 93, the rotating ball seat 93 is clamped with the mounting seat 91 by the arc-shaped clamping block 94, so that the initial position of the rotating ball seat 93 can be positioned.

[0030] The outside of the rotating ball seat 93 is fixed with connecting spring one 95, and the connecting spring one 95 is arranged in four groups about the rotating ball seat 93, so that the rotating ball seat 93 can be uniformly subjected to the elastic force of the connecting spring one 95, and the rotating ball seat 93 is elastically connected with the mounting seat 91 by the connecting spring one 95, the elastic force of the connecting spring one 95 is greater than the resistance of the magnetorheological fluid in the filling cavity one 92 and the clamping force of the arc-shaped clamping block 94 in the non-magnetic state, and the gravity of the sensor, so that when the rotating ball seat 93 returns to the initial position after subsequent rotation, the arc-shaped clamping block 94 can be clamped with the mounting seat 91 by the elastic force of the connecting spring one 95, so that the rotating ball seat 93 can be reset, and the inside of each group of rotating ball seat 93 is slidably provided with mounting sleeve 96, stress sensor 30, vibration transducer 40 and vibration sensor 50 are fixed with mounting sleeve 96, and the outside of the mounting sleeve 96 is fixed with fixing ring 97, the inside of the rotating ball seat 93 is provided with filling cavity two 98, and the filling cavity two 98 is communicated with the filling cavity one 92, and the filling cavity two 98 and the filling cavity one 92 are filled with magnetorheological fluid, and the magnetorheological fluid can flow in the two cavities, and the mounting sleeve 96 and the rotating ball seat 93 are sealed, which can prevent the magnetorheological fluid from leaking from the sliding part of the rotating ball seat 93 and the mounting sleeve 96.

[0031] The connecting spring two 99 is fixed above both sides of the fixed ring 97, and the fixed ring 97 is elastically connected with the rotating ball seat 93 through the connecting spring two 99. The elastic force of the connecting spring two 99 is greater than the resistance of the magnetorheological fluid in the filling cavity two 98 and the gravity of the sensor in the non-magnetic state, so that the compressed connecting spring two 99 can be reset by the elastic force of the connecting spring two 99. The outside of each filling cavity one 92 is provided with an electromagnetic coil 910, the electromagnetic coil 910 is fixed in the mounting seat 91, and the electromagnetic coil 910 is electrically connected with the wire 80 and controlled by the control equipment of the power generation output end. When the sliding block 8 normally drives the mounting seat 91 and the corresponding stress sensor 30, vibration transducer 40 and vibration sensor 50 in the mounting seat 91 to move, the rotating ball seat 93 and the mounting sleeve 96 are in the initial state, and the electromagnetic coil 910 is in the energized state. At this time, under the action of magnetic force, the magnetorheological fluid in the filling cavity two 98 and the filling cavity one 92 will harden, so that the rotating ball seat 93 and the mounting sleeve 96 cannot move and remain in the initial state, so that the sensor can normally detect and vibrate. When the tide rises and falls, the water flow speed changes greatly, and there are often gravel particles in the water flow. The water wheel blade 4 may be indented on the surface due to long-term periodic impact or gravel particle impact, so that the inner cavity 20 will have a slight bulge. At this time, if each sensor is kept moving on the surface of the inner cavity 20, the bulge will hinder the movement of the sensor, and even the sensor and the water wheel blade 4 will be damaged by hard extrusion, thereby affecting the normal detection and vibration. At the same time, if the water wheel blade 4 is damaged, it will also affect the efficiency of the device tide power generation.

[0032] At this time, the inner surface of the moving path in the cavity 20 can be identified by the visual sensor 60. When a protrusion is found on the moving path, the control device will cause the electromagnetic coil 910 to be powered off. After the power is turned off, the magnetorheological fluid in the filling cavity two 98 and the filling cavity one 92 will lose magnetism and soften, allowing the rotating ball seat 93 to stretch one side of the connecting spring one 95 and compress the other side of the connecting spring one 95 to rotate, and allowing the mounting sleeve 96 to move by compressing the connecting spring two 99, so that the installed stress sensor 30, vibration transducer 40 and vibration sensor 50 can have the ability to rotate and compress. When passing through the protrusion, the movable ability is used to avoid being blocked or hard pressed, thereby facilitating smooth detection and vibration of the water turbine blade 4, while avoiding damage to multiple sensors and blades to ensure the efficiency and stability of tidal power generation. After the sensor passes through the protrusion, the elastic reset of the connecting spring one 95 and the connecting spring two 99 allows the stress sensor 30, vibration transducer 40 and vibration sensor 50 to reset, and after resetting, the electromagnetic coil 910 is powered on again, allowing the magnetorheological fluid to harden and reposition the rotating ball seat 93 and the mounting sleeve 96, allowing the stress sensor 30, vibration transducer 40 and vibration sensor 50 to continue detection and vibration processing. The arc-shaped clamping block 94 is arc-shaped, so that even if the rotating ball seat 93 has a slight deviation, it can still be clamped on the mounting seat 91 to achieve rapid positioning, shorten the reset time, and improve the detection efficiency.

[0033] To solve the problem of large water flow speed change during tidal fluctuation, the blade is easily impacted to cause cracks, and the service life of the power generation device is reduced, such as Figures 1-3 and Figure 9 and Figure 10 The following preferred technical solutions are provided: As shown in Figure 3 and Figure 9 The center seat 5 includes a mounting cavity 51 arranged at one end of the plurality of water turbine blades 4, and a fixed frame 52 is fixed inside the mounting cavity 51. One end of the fixed frame 52 is rotatably mounted with an electric push cylinder 53, the electric push cylinder 53 is electrically connected with the wire 80, and is controlled by the control device of the power generation output end.

[0034] The outer side of the electric push cylinder 53 is rotatably mounted with a rotating ring 54, the rear surface of the rotating ring 54 is fixed with a supporting slide 55, and the supporting slide 55 is slidably connected with the mounting cavity 51. The supporting slide 55 is limitingly arranged in the T-shaped sliding groove on the inner surface of the mounting cavity 51, and the fixed frame 52, the electric push cylinder 53 and the supporting slide 55 are arranged in two groups about the rotating ring 54. The push-pull movement of the electric push cylinder 53 can make the rotating ring 54 rotate forward and backward, and the rotating ring 54 can rotate radially in the mounting cavity 51 by sliding the supporting slide 55.

[0035] The outer surface of the rotating ring 54 is fixed with a plurality of fixed rods 56, and the outer part of each group of fixed rods 56 is provided with a rocker arm 57, the surface of each group of rocker arms 57 is provided with a sliding groove 58, and the fixed rod 56 and the sliding groove 58 are slidably connected, and one side surface of each group of rocker arms 57 is fixed with a rotating shaft one 59, and one end of each group of rotating shafts one 59 is respectively fixedly connected with the water wheel blade 4, the water wheel blade 4 is rotatably connected with the mounting cavity 51 through the rotating shaft one 59, and the rotating part is sealingly arranged, and the rotating shaft one 59 is hollowly arranged, and the fixed part of the rotating shaft one 59 and the rocker arm 57 is provided with a through hole, so that the lead wire 80 in the water wheel blade 4 can be introduced into the mounting cavity 51, when the rotating ring 54 and the fixed rod 56 are driven to rotate forward and reverse, the sliding ability between the fixed rod 56 and the sliding groove 58 can make the rocker arm 57 swing left and right, so that the swing of the rocker arm 57 can drive the water wheel blade 4 to rotate through the rotating shaft one 59.

[0036] When the stress sensor 30 detects that the tidal current impact causes the local stress of the water wheel blade 4 to exceed the standard, the control device immediately triggers the electric push cylinder 53 to contract and pull, according to the above, the contraction and pulling of the electric push cylinder 53 finally makes the plurality of water wheel blades 4 rotate synchronously, realizes the rapid adjustment of the water wheel blade 4, reduces the impact force area of the blade and the tidal current, and reduces the further pulling and impact of the tidal current on the blade from the source, significantly delays the damage speed of the blade, greatly improves the safety and service life of the blade in the tidal periodic strong impact working condition, avoids the tidal power generation interruption caused by the blade hidden danger treatment, considers the safety protection and power generation continuity, and has sufficient time to let the staff maintain the marine power generation device after the adjustment and protection, and when the stress sensor 30 detects that the stress threshold of the dirt thickness is large, the extension of the electric push cylinder 53 can finally make the water wheel blade 4 rotate, and the water wheel blade 4 can also be adjusted to increase the impact area and impact force of the tidal current on the water wheel blade 4, and cooperate with the high-frequency vibration of the vibration transducer 40, so that the dirt on the surface of the water wheel blade 4 is better removed.
