Description

Technical Field

[0001] This invention relates to a safety monitoring device for offshore wind power generation, belonging to the field of wind power generation technology. Background Technology

[0002] Wind turbines typically consist of components such as a rotor, generator, yaw mechanism, tower, speed limiting safety mechanism, and energy storage device. To ensure the structural safety of offshore wind power generation equipment, regular manual inspections are often required to conduct overall checks on the installation platform and base of the offshore wind power generation equipment. This necessitates professional inspection personnel traveling by boat to the turbine location, climbing ladders or lifting equipment to access the platform, and using visual observation and measuring tapes to inspect the corresponding locations. However, manual inspections are inefficient and pose high safety risks. Therefore, in recent years, camera-based visual monitoring methods have been introduced as an effective supplement.

[0003] For example, Chinese utility model patent application number 202420788855.4 discloses a safety monitoring device for offshore wind power generation, including four mounting columns and an installation platform. The installation platform is fixedly installed on top of the four mounting columns, and a wind power generation device is fixedly installed on top of the installation platform. A safety monitoring mechanism is set on the side wall of the mounting columns. The safety monitoring mechanism includes platform railings, berthing support railings, cameras, and detection components. A power distribution box is fixedly installed on top of the installation platform. This reference example provides a platform railing on the side wall of the mounting columns, providing a foothold for monitoring personnel to manually inspect the structural safety of the mounting columns and the installation platform from within the railing. Simultaneously, this solution uses a fixed camera on the side wall of the mounting columns to assist monitoring personnel in remotely viewing the corrosion on the column surface. However, the camera in this reference example is fixedly installed, limiting the monitoring angle and range, making it difficult to achieve comprehensive coverage monitoring of the entire circumference of the columns at different heights. Therefore, improvements are urgently needed. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, this invention designs a safety monitoring device for offshore wind power generation. By moving the slide table longitudinally along the slide rail, the monitoring camera can reach different height positions of the column. Combined with the multi-angle rotation adjustment driven by the second and third motors, it can achieve full-circumference and full-height monitoring of the column without blind spots, overcoming the limitation of the viewing angle of fixed cameras.

[0005] To achieve the above objectives, the present invention employs the following technology. A safety monitoring device for offshore wind power generation includes a modular base plate. One side of the modular base plate is mounted on a platform column via a clamp assembly. The other side of the modular base plate is provided with a slide rail along its length. A slide table is slidably mounted on the slide rail. An adjustment mechanism is mounted on the slide table. A monitoring camera is mounted on the adjustment mechanism. A drive mechanism for driving the slide table to slide along the direction of the slide rail is also mounted on the slide table. The adjustment mechanism includes a U-shaped base. A rotating shaft is rotatably connected to the U-shaped groove of the base via a worm gear assembly. Both ends of the rotating shaft are fixedly connected to a swing plate. A third motor is fixedly mounted on the swing plate. The output end of the third motor is driven by a drive gear. A driven gear that meshes with the drive gear is also rotatably mounted on the swing plate. A rotating seat is coaxially fixedly connected to the driven gear. The monitoring camera is fixedly mounted on the rotating seat.

[0006] Furthermore, the worm gear assembly includes a second motor, a second worm wheel, and a second worm. The second motor is fixed in the U-shaped groove of the base, the second worm is fixed on the output shaft of the second motor, and the second worm wheel is fixedly sleeved in the middle of the rotating shaft and meshes with the second worm.

[0007] Furthermore, the driving mechanism includes a first motor fixed on the slide, the output end of the first motor being connected to a first worm gear, a first worm wheel meshing with the first worm gear being rotatably mounted on the slide, a drive gear being coaxially fixedly connected to the first worm wheel, and a rack meshing with the drive gear being fixedly provided along the length direction of the combined base plate.

[0008] Furthermore, mounting plates are installed at intervals on the sliding platform, and a photovoltaic power supply mechanism is installed on the mounting plate. The photovoltaic power supply mechanism includes a photovoltaic panel, and the photovoltaic panel is fixedly connected to the mounting plate by four rectangular connecting frames. The length of the two connecting frames at the upper end of the mounting plate is less than the length of the two connecting frames at the lower end of the mounting plate.

[0009] Furthermore, a photovoltaic cleaning mechanism is also installed on the photovoltaic panel. The photovoltaic cleaning mechanism includes a cleaning rod and a cleaning brush drive motor. The cleaning rod is set against the front of the photovoltaic panel, and a cleaning brush is set on the side of the cleaning rod that is in contact with the photovoltaic panel. The cleaning brush drive motor is fixed to the back of the photovoltaic panel, and a lead screw is driven to the output end of the cleaning brush drive motor. The free end of the lead screw is rotatably connected to the mounting block fixed to the back of the photovoltaic panel. A threaded hole plate is also threaded onto the lead screw. A connecting rod is fixedly installed on the threaded hole plate, and the two ends of the connecting rod are fixedly connected to the two ends of the cleaning rod.

[0010] Furthermore, a spray pipe is fixed at intervals on the side of the cleaning rod away from the photovoltaic panel, and multiple nozzles are evenly spaced on the spray pipe. The input end of the spray pipe is connected to a water pump fixed on the mounting plate, and the water pump is connected to a water tank fixed on the platform column.

[0011] Furthermore, guide rails are installed on both sides of the photovoltaic panel, and the two ends of the cleaning rod are slidably connected to the two guide rails respectively.

[0012] Furthermore, the modular substrate includes multiple unit boards that can be detachably spliced ​​in sequence. Each unit board has a snap-fit ​​groove at its end. When two adjacent unit boards are spliced ​​together, the two snap-fit ​​grooves are aligned with each other, and a splicing block is detachably snapped between the two snap-fit ​​grooves. Bolts are connected between the splicing block and the two unit boards.

[0013] Furthermore, the combined substrate is fixed with multiple pairs of second fixing plates along its length, and a clamping assembly is provided between each pair of second fixing plates. The clamping assembly includes two semi-circular clamping clamps, and a first fixing plate is integrally fixed to both ends of the clamping clamps. A screw is provided through the two first fixing plates and the second fixing plate on the same side, and nuts are threaded onto both ends of the screw.

[0014] Furthermore, rubber pads are installed on the inner sides of both the clamping clamp and the first fixing plate.

[0015] Compared with the prior art, the present invention has the following features and beneficial effects: This invention uses a first motor to drive a slide table to slide longitudinally along a slide rail, allowing the monitoring camera to reach different height positions on the platform column. Combined with a second motor driving a second worm gear and a second worm wheel, the camera's pitch angle can be flexibly adjusted. Furthermore, a third motor drives a drive gear and a driven gear, enabling the camera to rotate freely in the horizontal direction. Through multi-position adjustment, the monitoring camera can monitor the platform column and power generation platform from all directions and angles in three-dimensional space, effectively overcoming the limitations of fixed cameras in existing technologies, such as limited viewing angles and small monitoring ranges.

Detailed Implementation

[0018] The present invention will now be described in more detail with reference to the embodiments.

[0019] Example 1 Please see Figures 1 to 5 as well as Figure 9 and Figure 10 The offshore wind power generation safety monitoring device of this embodiment includes a modular base plate 1, one side of which is mounted on the platform column 100 via a clamp assembly 2.

[0020] Platform column 100 is a support column structure for offshore wind power generation devices. It is fixedly installed on the seabed and serves a supporting function.

[0021] A slide rail 8 is provided on the other side of the modular substrate 1 along the length direction. The slide rail 8 can be welded and fixed to the modular substrate 1 or fixed to the modular substrate 1 by bolts 7. In this embodiment, bolts 7 are used for fixing.

[0022] A slide table 3 is slidably mounted on the slide rail 8. An adjustment mechanism is mounted on the slide table 3. A monitoring camera 5 is mounted on the adjustment mechanism. The slide table 3 is also equipped with a drive mechanism for driving the slide table 3 to slide along the set direction of the slide rail 8.

[0023] Specifically, the adjustment mechanism includes a U-shaped base 14, a rotating shaft 15 rotatably connected to the U-shaped groove of the base 14 via a worm gear assembly, both ends of the rotating shaft 15 being fixedly connected to a swing plate 16, a third motor 21 being fixedly mounted on the swing plate 16, a drive gear 22 being driven to the output end of the third motor 21, a driven gear 23 meshing with the drive gear 22 being rotatably mounted on the swing plate 16, a rotating seat 20 being coaxially fixedly connected to the driven gear 23, and a monitoring camera 5 being fixedly mounted on the rotating seat 20.

[0024] The worm gear assembly includes a second motor 17, a second worm wheel 19, and a second worm 18. The second motor 17 is fixed in the U-shaped groove of the base 14, the second worm 18 is fixed on the output shaft of the second motor 17, and the second worm wheel 19 is fixedly sleeved in the middle of the rotating shaft 15 and meshes with the second worm 18.

[0025] The drive mechanism includes a first motor 11 fixed on the slide table 3. The output end of the first motor 11 is connected to a first worm gear 12. A first worm wheel 13 that meshes with the first worm gear 12 is also rotatably mounted on the slide table 3. A drive gear 10 is coaxially fixedly connected to the first worm wheel 13. A rack 9 that meshes with the drive gear 10 is fixedly provided along the length of the combined base plate 1.

[0026] When the first motor 11 starts, it drives the first worm gear 12 to rotate. The first worm gear 12 drives the first worm wheel 13 to rotate through meshing transmission. The first worm wheel 13 drives the coaxial gear 10 to rotate. The gear 10 meshes and rolls along the rack 9, thereby driving the entire slide table 3 to slide up and down along the setting direction of the slide rail 8 (i.e., the length direction of the platform column 100). Thus, the monitoring camera 5 installed on the slide table 3 can reach different height positions of the platform column 100, realizing longitudinal multi-height monitoring.

[0027] When the second motor 17 starts, the second motor 17 drives the second worm gear 18 to rotate. The second worm gear 18 drives the second worm wheel 19 to rotate through meshing transmission. The second worm wheel 19 drives the rotating shaft 15 to rotate. The rotating shaft 15 drives the swing plates 16 at both ends to swing synchronously, thereby realizing the adjustment of the tilt angle of the monitoring camera 5.

[0028] When the third motor 21 is started, the third motor 21 drives the drive gear 22 to rotate. The drive gear 22 drives the driven gear 23 to rotate through meshing transmission. The driven gear 23 drives the rotating seat 20 and the monitoring camera 5 to rotate around the axis, thereby realizing the full-angle adjustment of the monitoring camera 5 in the horizontal direction.

[0029] As can be seen from the above description, by driving the slide table 3 to slide longitudinally along the slide rail 8 via the first motor 11, the monitoring camera 5 can reach different height positions of the platform column 100. With the second worm gear 18 and the second worm wheel 19 driven by the second motor 17 meshing and transmitting, the tilt angle of the monitoring camera 5 can be flexibly adjusted. Furthermore, with the third motor 21 driving the drive gear 22 and the driven gear 23 meshing and transmitting, the monitoring camera 5 can rotate freely in the horizontal direction. Through multi-position adjustment, the monitoring camera 5 can monitor the platform column 100 and the power generation platform from all directions and multiple angles in three-dimensional space, effectively overcoming the shortcomings of the fixed camera in the prior art, which has a limited viewing angle and small monitoring range.

[0030] Meanwhile, the entire monitoring process is remotely controlled and driven by the first motor 11, the second motor 17 and the third motor 21. The monitoring images can be remotely transmitted to the control terminal. Monitoring personnel do not need to be on-site at sea, nor do they need to climb ladders or stand on platform railings to work. This fundamentally eliminates the safety risks of manual inspection and is particularly suitable for deep-sea wind farms that are far from the shore and in harsh environments.

[0031] Furthermore, mounting plates 48 are installed at intervals on the slide table 3, and photovoltaic power supply mechanisms are installed on the mounting plates 48.

[0032] Specifically, the photovoltaic power supply mechanism includes a photovoltaic panel 4, which is fixedly connected to a mounting plate 48 by four rectangular connecting frames 49. The length of the two connecting frames 49 located at the upper end of the mounting plate 48 is shorter than the length of the two connecting frames 49 located at the lower end of the mounting plate 48.

[0033] As described above, during installation, due to the shorter upper two connecting brackets 49 and the longer lower two connecting brackets 49, the photovoltaic panel 4 is installed at an angle relative to the mounting plate 48 and the sliding table 3. The upper edge of the photovoltaic panel 4 is close to the mounting plate 48, and the lower edge is far from the mounting plate 48, so that the light-receiving surface of the photovoltaic panel 4 faces upward at a certain angle. When sunlight shines, the light-receiving surface of the photovoltaic panel 4 obtains a larger effective light-receiving area due to the tilted setting, and the light enters the surface of the photovoltaic panel 4 at a closer vertical angle, thereby improving the photoelectric conversion efficiency of the photovoltaic panel 4. The photovoltaic panel 4 converts solar energy into electrical energy, which powers the first motor 11, the second motor 17, the third motor 21, and the monitoring camera 5 through wires, realizing the autonomous power supply of the monitoring device.

[0034] Meanwhile, the photovoltaic panel 4 is fixedly connected to the mounting plate 48 through the connecting frame 49, and maintains a certain distance from other components on the slide table 3, avoiding mutual shading and interference between components. The tilted photovoltaic panel 4 ensures efficient power generation while providing ample space for the installation and movement of other components below, making the overall structure of the slide table 3 more compact and reasonable.

[0035] Furthermore, the modular substrate 1 includes multiple unit boards that can be detachably spliced ​​in sequence. In this embodiment, the number of modular substrates 1 is two.

[0036] The unit panel has a snap-fit ​​groove at its end. When two adjacent unit panels are spliced ​​together, the two snap-fit ​​grooves are aligned with each other. A splicing block 6 is detachably snapped between the two snap-fit ​​grooves, and bolts 7 are connected between the splicing block 6 and the two unit panels.

[0037] As can be seen from the above description, the modular base plate 1 adopts a structural design in which multiple unit plates can be disassembled and spliced ​​in sequence. The number of splicing unit plates can be flexibly selected according to the actual height of the platform column 100 and the required monitoring range, and the modular base plate 1 of different lengths can be spliced ​​to form a modular base plate 1. It has strong adaptability and can meet the installation requirements of offshore wind turbines of different specifications. There is no need to customize the base plate separately for each column height, which reduces manufacturing costs and inventory pressure.

[0038] Meanwhile, the two adjacent unit panels are first positioned and limited by the snap-fit ​​groove and the splicing block 6, and then fastened and locked by the bolt 7. The dual fixing method of snap-fit ​​and bolt connection effectively enhances the connection strength and shear resistance of the splicing point, ensuring that the composite base plate 1 maintains the integrity and stability of the structure under complex loads such as strong winds and wave vibrations at sea, and avoiding the hidden danger of loosening or separation at the splicing point.

[0039] Furthermore, the modular base plate 1 is fixed with multiple pairs of second fixing plates 204 along its length. Each pair of second fixing plates 204 is provided with a clamping assembly 2. The clamping assembly 2 includes two semi-circular clamping clamps 201. Both ends of the clamping clamps 201 are integrally fixed with first fixing plates 202. A screw 203 is provided through the two first fixing plates 202 and the second fixing plates 204 on the same side. Nuts are threaded onto both ends of the screw 203.

[0040] As can be seen from the above description, during installation, the two clamping hoops 201 are fastened to each other from both sides of the platform column 100, so that the two clamping hoops 201 surround and hug the outer wall of the platform column 100. At the same time, the second fixing plate 204 on the combined base plate 1 is aligned with the two first fixing plates 202 on the same side. Then, the screw 203 passes through the two first fixing plates 202 and the second fixing plate 204 on the same side in sequence. Finally, nuts are threaded onto both ends of the screw 203 and tightened.

[0041] Because the modular base plate 1 is provided with multiple pairs of second fixing plates 204 and corresponding multiple sets of clamping assemblies 2 along its length, the modular base plate 1 is simultaneously fixedly connected to the platform column 100 at multiple positions along its length, achieving stable installation. It is also fixed at multiple height positions simultaneously, which can effectively resist strong winds, wave impacts and vibration loads generated by the operation of the unit at sea, ensuring that the modular base plate 1 is stably fixed on the platform column 100 for a long time and is not easy to loosen or slip.

[0042] The clamp assembly 2 consists of only two semi-circular clamping clamps 201, a screw 203, and a nut. It has few parts and a simple structure. During installation, simply fasten the two clamping clamps 201, insert the screw 203, and tighten the nut to complete the fixation. No welding or complicated alignment operations are required, resulting in high installation efficiency. During disassembly, simply loosen the nut and pull out the screw 203 to remove it. This facilitates later maintenance and position adjustment, making it suitable for high-altitude offshore operations.

[0043] Furthermore, rubber pads are installed on the inner sides of both the clamping clamp 201 and the first fixing plate 202.

[0044] As can be seen from the above description, during the locking process of the clamp assembly 2, as the nut is gradually tightened, the tensile and compressive forces generated by the screw 203 are transmitted to the first fixing plate 202 and the second fixing plate 204. The rubber pad undergoes elastic deformation under pressure, filling the micro gaps on the contact surface, thereby forming a tight fit between the clamping clamp 201 and the platform column 100, and between the first fixing plate 202 and the second fixing plate 204.

[0045] Example 2 Please see Figures 6 to 8 In this embodiment of the offshore wind power safety monitoring device, based on the above embodiment one, a photovoltaic cleaning mechanism is also installed on the photovoltaic panel 4. The photovoltaic cleaning mechanism includes a cleaning rod 41 and a cleaning brush drive motor 43. The cleaning rod 41 is attached to the front of the photovoltaic panel 4, and a cleaning brush is provided on the side of the cleaning rod 41 that is attached to the photovoltaic panel 4.

[0046] The cleaning brush drive motor 43 is fixed on the back of the photovoltaic panel 4, and the output end of the cleaning brush drive motor 43 is connected to the lead screw 46. The free end of the lead screw 46 is rotatably connected to the mounting block 410 fixed on the back of the photovoltaic panel 4. The lead screw 46 is also threaded with a threaded hole plate 47. A connecting rod 411 is fixedly installed on the threaded hole plate 47. The two ends of the connecting rod 411 are fixedly connected to the two ends of the cleaning rod 41.

[0047] As can be seen from the above description, the marine environment is characterized by heavy salt fog and frequent seabird activity. The surface of photovoltaic panel 4 is prone to accumulating pollutants such as salt fog crystals, dust, and bird droppings, which seriously affects the light transmittance and photoelectric conversion efficiency. Therefore, it is necessary to clean photovoltaic panel 4 regularly.

[0048] When it is necessary to clean the photovoltaic panel 4, the cleaning brush drive motor 43 is started, which drives the lead screw 46 to rotate. Since the perforated plate 47 is threadedly engaged with the lead screw 46, and the perforated plate 47 forms a sliding limit with the edge of the photovoltaic panel 4 through the connecting rod 411 and the cleaning rod 41, the perforated plate 47 cannot rotate with the lead screw 46 when the lead screw 46 rotates. Instead, it moves along the axial direction of the lead screw 46. When the perforated plate 47 moves, it drives the cleaning rod 41 and the cleaning brush to move synchronously along the surface of the photovoltaic panel 4 through the connecting rod 411. During the movement, the cleaning brush sweeps the front of the photovoltaic panel 4 to remove pollutants such as salt spray crystals, dust, and bird droppings accumulated on the surface. When the cleaning brush drive motor 43 rotates forward and reverse, the cleaning rod 41 moves in the opposite direction. Through reciprocating motion, the surface of the photovoltaic panel 4 is thoroughly cleaned.

[0049] The cleaning brush drive motor 43 drives the lead screw 46 to rotate, which drives the cleaning rod 41 and the cleaning brush to automatically reciprocate and clean the surface of the photovoltaic panel 4. Pollutants can be cleaned regularly without manual intervention, ensuring that the photovoltaic panel 4 maintains high light transmittance and power generation efficiency for a long time, and providing a continuous and stable power supply for the monitoring device. Furthermore, the threaded engagement between the lead screw 46 and the perforated plate 47 is used as a transmission mechanism to convert the rotational motion of the lead screw 46 into the linear movement of the perforated plate 47, resulting in smooth transmission, high precision, and fast response.

[0050] Furthermore, a spray pipe 42 is fixed at intervals on the side of the cleaning rod 41 away from the photovoltaic panel 4. Multiple nozzles 412 are evenly spaced on the spray pipe 42. The input end of the spray pipe 42 is connected to a water pump 44 fixed on the mounting plate 48. The water pump 44 is connected to a water tank fixed on the platform column 100.

[0051] As can be seen from the above description, when the photovoltaic panel 4 needs to be cleaned, the water pump 44 is started, and the water stored in the water tank is pumped into the water pump 44 through the water inlet pipe. After being pressurized by the water pump 44, the water is pumped into the spray pipe 42. The water flows along the length of the spray pipe 42 and is distributed to each nozzle 412. Finally, it is sprayed out from the nozzle 412. Since the nozzles 412 are spaced apart and face the cleaning brush and the surface of the photovoltaic panel 4, the sprayed water is evenly sprayed on the front of the photovoltaic panel 4 and the cleaning brush.

[0052] While the water pump 44 is working, the cleaning brush drive motor 43 drives the lead screw 46 to rotate, which in turn drives the wire hole plate 47 to move axially along the lead screw 46. The wire hole plate 47 drives the cleaning rod 41 and the spray pipe 42 to move synchronously along the surface of the photovoltaic panel 4 through the connecting rod 411. As the spray pipe 42 moves with the cleaning rod 41, the nozzle 412 continuously sprays water onto the surface of the photovoltaic panel 4 to wet and wash away pollutants such as salt spray crystals and dust on the surface of the photovoltaic panel 4, softening and washing away some of the weakly attached dirt. At the same time, the cleaning brush brushes the wetted surface of the photovoltaic panel 4 as it moves with the cleaning rod 41, further removing stubborn stains. The sprayed water and the brushing action work together to achieve wet cleaning, which significantly improves the cleaning effect.

[0053] Furthermore, guide rails 45 are installed on both sides of the photovoltaic panel 4. The two ends of the cleaning rod 41 are slidably connected to the two guide rails 45 respectively. The guide rails 45 constrain and guide the movement direction of the cleaning rod 41, ensuring that the cleaning rod 41 always moves along a straight trajectory and that the two ends of the cleaning rod 41 remain synchronized and do not deviate.

[0054] The working principle of the present invention is as follows: the combined base plate 1 is clamped and fixed to the platform column 100 by the clamping assembly 2. The rubber pad deforms elastically during the clamping process to increase the friction and protect the anti-corrosion layer of the column.

[0055] When the equipment is running, the first motor 11 drives the first worm gear 12 to rotate. After being reduced in speed by the first worm wheel 13, the gear 10 is driven to mesh and roll along the rack 9 fixed on the combined base plate 1. This causes the slide table 3, carrying the monitoring camera 5, photovoltaic panel 4 and photovoltaic cleaning mechanism, to slide up and down along the slide rail 8, achieving longitudinal movement at different heights.

[0056] At the same time, the second motor 17 drives the second worm gear 18 and the second worm wheel 19 to mesh and transmit power, causing the rotating shaft 15 and the swing plate 16 to swing to adjust the pitch angle of the monitoring camera 5. The third motor 21 drives the driving gear 22 and the driven gear 23 to mesh and transmit power, causing the rotating seat 20 and the monitoring camera 5 to rotate horizontally. Through the coordinated cooperation of pitch and horizontal rotation, all-round monitoring without blind spots is achieved.

[0057] The photovoltaic panel 4 is installed at an angle on the mounting plate 48 via four connecting frames 49 of different lengths, converting solar energy into electrical energy to power the first motor 11, the second motor 17, the third motor 21, the monitoring camera 5, the cleaning brush drive motor 43, and the water pump 44.

[0058] When the surface of the photovoltaic panel 4 is contaminated, the water pump 44 starts and sprays water from the water tank onto the surface of the photovoltaic panel 4 through the spray pipe 42 and the evenly spaced nozzles 412. At the same time, the cleaning brush drive motor 43 drives the lead screw 46 to rotate, and the wire hole plate 47 moves along the axial direction of the lead screw 46 and drives the connecting rod 411 and the cleaning rod 41 to slide back and forth along the guide rails 45 on both sides of the photovoltaic panel 4. The cleaning brush on the cleaning rod 41 brushes the surface of the photovoltaic panel 4. The spraying and brushing work together to achieve automatic wet cleaning.

[0059] The entire monitoring process achieves comprehensive automated inspection of the platform column 100 through the combination of longitudinal movement, multi-angle adjustment, autonomous power supply, and automatic cleaning.
