Description

Technical Field

[0001] The present invention belongs to the field of offshore photovoltaic electric field pile group monitoring, and in particular relates to a pile foundation scour monitoring system and method for offshore photovoltaic electric field pile groups. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] Compared with photovoltaic power plants on land and lakes, the biggest challenge facing offshore photovoltaic power plants is the complex marine dynamic environment. The piles of offshore photovoltaic power plants with pile foundations are at risk of scouring. The displacement, tilting, and vibration of the piles, floating bodies, and power generation panels under extreme dynamic conditions will threaten the safe operation of the power plant. Therefore, it is necessary to monitor the scouring status of the pile foundations of offshore photovoltaic power plants in real time.

[0023] The beneficial effects of the present invention are:

[0024] (1) The present invention starts the driving motor to rotate the linkage ring and the ratchet ring so that the sonar depth sounder can move arbitrarily on the track, and can enable the sonar depth sounder to monitor the pile foundation on the seabed at different angles according to different monitoring requirements, so that the distance between the sonar depth sounder and the seabed is adjustable, thereby reducing the limitations of the pile foundation flushing system for offshore photovoltaic power field pile groups during use, and at the same time improving the monitoring effect of the pile foundation flushing system for offshore photovoltaic power field pile groups;

[0044] like Figure 1-Figure 9 As shown, an embodiment of the present invention provides a pile foundation scour monitoring system for offshore photovoltaic power field pile groups, comprising: a running track 2, a displacement ring 4, a drive slider, a rotation angle monitoring module and a sonar depth sounder 6;

[0045] The running track 2 is arranged on the outside of each pile basic body 1 of the offshore photovoltaic power field pile group according to the set rules; the displacement ring 4 is clamped on the running track 2, the driving slider is fixed on the displacement ring 4, the rotation angle monitoring module is fixed on the displacement ring 4 through the displacement substrate 5, and the sonar depth sounder 6 is mounted on the rotation angle monitoring module; the driving slider is used to drive the displacement ring clamp 4 to drive the rotation angle monitoring module and the sonar depth sounder 6 mounted thereon to move along the running track.

[0046] In this embodiment, a running track is set up on the pile basic body through support rods.

[0047] In this embodiment, the rotation angle monitoring module includes a linkage ring 7 arranged on a plurality of displacement substrates 5, and the motor drives the ratchet ring 8 and the linkage ring 7 to rotate, thereby realizing the multi-angle monitoring function of the sonar depth sounder 6; the sonar depth sounder 6 is installed at both ends of the linkage ring 7, such as Figure 4 As shown; the pile foundation scour monitoring system 3 for offshore photovoltaic power field piles can be charged when returning to the starting position; wherein the structure of the ratchet swivel is as shown Figure 5 shown.

[0048] When using the pile foundation scour monitoring system for offshore photovoltaic power field pile groups, by operating the rotation angle monitoring module to operate the ratchet swivel 8, the sonar depth sounder 6 can monitor the situation around the pile base at different angles of the running track 2. The monitoring results are uploaded to the data center through the control panel for comparison and analysis with previous results, so that it can be quickly determined whether the scour at that location is serious; at the same time, the monitoring range is improved, so that the system of the present invention can monitor more data, which also reduces the cost of use and improves the accuracy of the monitoring results.

[0049] like Figure 2 As shown, the displacement base plate 5 of this embodiment is connected to the mounting square plate 9 by bolts, and the mounting square plate 9 is connected with a fitting resistance increasing mechanism; the fitting resistance increasing mechanism comprises a telescopic cylinder 10 arranged on the mounting square plate 9, and a displacement horizontal plate 11 is installed on the output end of the telescopic cylinder 10, and a force-holding scraping unit is arranged on the displacement horizontal plate 11; a displacement slide rod 12 is slidably arranged on the displacement horizontal plate 11, as shown in FIG. Figure 6 As shown, one end of the displacement slide bar 12 is connected to the displacement limit plate 13, and the other end passes through the displacement ring 4 and is connected to the displacement U seat 14. The displacement U seat 14 is connected to the reduction wheel 15 through the slow-motion obstacle avoidance component, and the reduction wheel 15 is connected to the running track 2. A guide square plate 16 is installed on the displacement U seat 14, and a guide square rod 17 is provided on the guide square plate 16. The guide square rod 17 is slidably connected to the guide base 18 provided on the displacement ring 4; a displacement spring 19 is sleeved on the displacement slide bar 11, and one end of the displacement spring 19 is connected to the displacement limit plate 13, and the other end is connected to the displacement cross plate 11;

[0050] After the driving slider installs the pile foundation flushing system for offshore photovoltaic power field piles at the running track 2, the L-shaped square rod 47 enters the auxiliary square box 48, and then the static contact piece 50 contacts the moving contact piece 49, indicating that the installation is completed. The control panel sends a start signal to the telescopic cylinder 10, so that its output end drives the displacement cross plate 11 to move, so that the displacement cross plate 11 drives the displacement slide bar 12 to move within the upper limit of the displacement ring 4 under the action of the displacement spring 19, thereby driving a number of displacement U seats 14 to move toward each other, so that a number of reduction wheels 15 move toward each other and contact the running track 2. At this time, the displacement cross plate 11 continues to move. Since the elastic force of the displacement spring 19 is less than the positioning spring 46, the displacement spring 19 is in a buffering state, and the displacement cross plate 11 moves on the displacement slide bar 12, which can enhance the friction between the reduction wheel 15 and the running track 2, until a number of reduction wheels 15 can limit the pile foundation flushing system for offshore photovoltaic power field piles on the running track. 2, the output end of the telescopic cylinder 10 can be stopped from moving. At this time, when the driving motor 24 on the driving slider stops working, the pile foundation scour monitoring system 3 for offshore photovoltaic power field piles will not fall off or dislocate on the running track 2, thereby reducing the energy consumption of the system and making the driving motor 24 not have to be in the starting state all the time, thereby improving the working time of the system underwater; at the same time, through a number of reduction wheels 15, the displacement ring 4 has a damping sense when moving, thereby avoiding shaking caused by too little resistance during movement, collision caused by moving too fast, etc., thereby improving the stability of the system during use and improving the monitoring effect; at the same time, it is worth mentioning that since the system is at different depths on the seabed, the pressure it is subjected to is also different. Through the above description, the contact pressure and friction between the reduction wheel 15 and the running track 2 can be adjusted in real time, thereby avoiding dislocation caused by excessive pressure at a deep depth, thereby reducing the limitations of the system during use.

[0051] like Figure 3As shown, the drive slider of this embodiment includes a driving square column 20 slidably arranged on the displacement ring 4, and a driving base 21 is symmetrically arranged on the side of the driving square column 20, and the two driving bases 21 are commonly connected to a driving shaft 22, and a driving wheel 23 is installed on the driving shaft 22, and the driving wheel 23 is connected with the running track 2; a driving motor 24 is installed on the driving shaft 22, and the driving motor 24 is connected to the driving square column 20 through a mounting clamp 25; a driving spring 26 is sleeved on the driving square column 20, and one end of the driving spring 26 is connected to the outer wall of the displacement ring 4, and the other end is connected to the driving limit plate 27; the The driving square column 20 is provided with a plurality of locking circular grooves 34, one of which is matched with a locking circular rod 35, the locking circular rod 35 passes through the displacement circular ring 4 and is connected with a locking horizontal plate 36, the locking horizontal plate 36 is slidably connected with a locking sliding column 37 provided on the displacement circular ring 4; a locking spring 38 is sleeved on the locking sliding column 37, one end of the locking spring 38 is connected with the locking horizontal plate 36, and the other end is connected with a locking limit plate 39; a lifting square handle 40 is provided on the locking horizontal plate 35; an L-shaped square rod 47 is symmetrically installed on the locking horizontal plate 36, and the L-shaped square rod 47 is matched with an auxiliary square box 48 provided on the displacement circular ring 4; Figure 7 As shown, a moving contact piece 49 is installed in the auxiliary square box 48, and the moving contact piece 49 is connected with a stationary contact piece 50 provided on the L-shaped square rod 47, and the contact between the stationary contact piece 50 and the moving contact piece 49 is connected with the control panel.

[0052] When the operator monitors the pile foundation, the operator sets the displacement ring 4 on the running track 2 and then pulls the lifting handle 40 upwards, so that the locking horizontal plate 36 moves to the upper limit position of the locking sliding column 37, and the locking spring 38 is in a buffering state, and then the locking round rod 35 on the locking horizontal plate 36 is no longer connected to the locking round groove 34, and the limit setting of the driving square column 20 is released. At this time, the driving square column 20 is pushed to move to the upper limit position of the displacement ring 4, and the driving spring 26 is in a buffering state, and then the several driving wheels 23 move toward each other and contact the running track 2, so that the system can be installed on the running track 2, and the sonar depth sounder 6 can be operated to monitor the pile basic body 1. At the same time, the above operation can be installed on piles of different sizes and diameters, reducing the limitations of the system when in use, and avoiding the need to replace the corresponding system for use when facing piles of different sizes; When several driving wheels 23 come into contact with the running track 2, the locking cross plate 36 is released, and the locking round rod 35 is reset and moved by the resetting of the locking spring 38, so that it enters the locking round groove 34 and limits the driving wheel 23 on the driving square column 20, so that it cannot be reset, thereby avoiding displacement and the like due to non-human factors. At the same time, the buffered driving spring 26 cannot be reset. The resulting elastic force strengthens the friction between the locking round groove 34 and the locking round rod 35, thereby improving the use effect and avoiding the system from being dislocated on the running track 2, thereby improving the safety of the system when in use; at this time, the driving motor can be started to drive the ratchet rotating ring 8 and the linkage ring 7 to rotate, so that the sonar depth sounder 6 can monitor the pile foundation on the seabed at different angles according to different monitoring needs, thereby reducing the limitations of the system when in use and improving the monitoring effect of the system.

[0053] like Figure 8 As shown, the force-holding scraping unit of this embodiment includes an L-shaped base plate 28 symmetrically arranged on the displacement horizontal plate 11, and a telescopic round rod 29 is installed on the L-shaped base plate 28. The telescopic round rod 29 passes through an auxiliary base plate 30 provided on the displacement base plate 5 and is connected to a scraping base 31. The two scraping bases 31 are commonly connected to a scraping ring block 32, and a lubricating pad 33 is provided on the inner side wall of the scraping ring block 32;

[0054] When the displacement cross plate 11 moves, it will also drive the L-shaped base plate 28 to move, so that the telescopic round rod 29 moves on the upper limit position of the auxiliary base plate 30, so that the plurality of scraper ring blocks 32 move toward each other. When it contacts the outer wall of the running track 2, the telescopic round rod 29 is in a buffering state, so that the scraper ring block 32 can better contact the running track 2, and the inner wall of the scraper ring block 32 contacts the running track 2, which can support the bottom of the displacement ring 4, avoid shaking of the system during use, and improve the stability of the displacement ring 4 during movement; at the same time, the lubricating pad 33 is provided, so that the resistance of the system during movement will not increase due to the contact between the scraper ring block 32 and the running track 2; at the same time, due to the scraper The bottom surface of the ring removing block 32 is provided with an inclined surface, so that the side of the bottom surface close to the running track 2 is sharper, and at the same time, this part is in contact with the running track 2, so that when it moves, it can clean up the impurities, garbage, etc. adhered to the running track 2, so as to avoid these things causing the system to shake during movement, so that the sonar depth sounder 6 will not shake when monitoring the scour at the pile foundation, thereby improving the stability of the sonar depth sounder 6 during use and improving the accuracy of monitoring; fixed-point monitoring is added to the above monitoring method, and the means used for monitoring are also different, so that the results of the two monitorings can be compared, so that the system has a higher fault tolerance rate during monitoring and improves the monitoring accuracy.

[0055] The slow-motion obstacle avoidance assembly of this embodiment includes a deceleration shaft 41 arranged on the deceleration wheel 15, and the two ends of the deceleration shaft 41 pass through the positioning slide grooves 42 provided on the displacement U seat 14 and are connected to the T-shaped square plate 43. The side surfaces of the T-shaped square plate 43 are symmetrically provided with positioning slide rods 44, and the positioning slide rods 44 are slidably connected to the positioning base plate 45 provided on the displacement U seat 14; the positioning slide rod 44 is sleeved with a positioning spring 46, one end of the positioning spring 46 is connected to the positioning base plate 45, and the other end is connected to the T-shaped square plate 43; the deceleration shaft 41 is slidably connected to the positioning slide groove 42, as shown in FIG. Fig. 9 As shown;

[0056] The reduction wheel 15 rotates as the system moves. When it encounters obstacles or debris on the running track 2, the reduction shaft 41 on the reduction wheel 15 moves on the positioning base plate 45 through the positioning slide bar 44 on the T-shaped square plate 43, so that the positioning spring 46 is in a buffering state, and then the reduction wheel 15 moves along the protrusion or depression on the running track 2. During the movement, several reduction wheels 15 are always in contact with the protrusion or depression, which can avoid the reduction wheel 15 not being in contact with the running track 2 and causing dislocation. The buffer zone provided by the positioning spring 46 makes the reduction wheel 15 have better obstacle avoidance performance. At the same time, several reduction wheels 15 are separately arranged, so that when one reduction wheel 15 is displaced, the other reduction wheels 15 can still be in good contact with the running track 2, which reduces the limitations of the pile foundation flushing system for offshore photovoltaic power field piles during use, improves the stability of the pile foundation flushing system for offshore photovoltaic power field piles during use, and indirectly leads to the improvement of the monitoring effect of the sonar depth sounder 6.

[0058] Step 1: Use the drive slider to drive the displacement ring clamp to drive the rotation angle monitoring module and the sonar depth sounder mounted thereon to move along the running track, so that the sonar depth sounder can monitor the scouring of the outer side of each pile basic body of the offshore photovoltaic power field pile group along the running track;

[0059] Step 2: Use the rotation angle monitoring module to drive the sonar depth sounder to rotate and move, so that the sonar depth sounder can perform multi-angle range monitoring on each pile basic body of the offshore photovoltaic power field pile group at the set position point.
