Description

Technical Field

[0001] The present invention belongs to the technical field of tower barrel transportation, and particularly relates to a tower barrel fixing device for an offshore wind power installation ship and a fixing method thereof. Background Art

[0002] In an offshore wind power project, a wind power tower barrel is the tower pole of a wind turbine, which mainly plays a supporting role in the wind turbine generator set and absorbs the vibration of the unit at the same time. The transportation of the wind power tower barrel is one of the important links in the whole project. When using an installation ship to transport the tower barrel over a long distance at sea, a fixing device is needed to fix the tower barrel. Among them, in the existing rope fixing method, when the ship sways for a long time in strong winds and waves, the connection effect and strength of the rope will be reduced to a certain extent, which is not conducive to long-term fixing. At the same time, for the existing fixing device, while achieving the fixing effect, it cannot monitor the tower barrel. That is, when the fixing effect of the fixing device on the tower barrel is insufficient, the tower barrel is prone to displacement, and the displacement situation of the tower barrel cannot be fed back in time, which will cause greater losses. Summary of the Invention

[0011] The square mounting column is symmetrically provided with limiting notches inside, wherein the limiting notches are connected with the transverse notches, and limiting blocks are slidably fitted in the limiting notches, and the limiting blocks are symmetrically connected to both sides of the connecting plate to limit the connecting plate and prevent the connecting plate from being separated from the transverse notches;

[0012] The right side of the connecting plate is connected with an inclined support plate, and the inclined support plate is connected to the inner abutment plate to enhance the stability of the connection between the connecting plate and the inner abutment plate;

[0013] The peripheral ring is connected to the left side of the top of the supporting plate.

[0014] Preferably, the monitoring mechanism further comprises a sliding notch and a sliding plate, wherein the sliding notch is provided inside the inner plate, and the sliding notch is symmetrically connected to both sides of the inner groove notch, the sliding plate is slidably fitted in the sliding notch, and the sliding plate is symmetrically connected to the tops of both sides of the feedback plate, so as to restrict the feedback plate and ensure the feedback plate's tightness against the tower;

[0015] A return spring is symmetrically connected to the left side of the feedback plate front and back, and the left end of the return spring is connected to the inner plate. The feedback plate is restricted by the return spring, so that the receiver in the feedback plate can be directly below the photoelectric transmitter without the influence of the friction of the tower.

The toothed ring is arranged on the left side of the peripheral ring member. The orbital plate members are circumferentially and arrayedly connected to the inner wall of the toothed ring, and the orbital plate members correspond to the square mounting posts one by one. The orbital notch is opened in the orbital plate member and runs through the orbital plate member from left to right. The linkage round bar is slidably fitted in the orbital notch, and the right end of the linkage round bar penetrates through the orbital notch and is connected to the connecting plate member. Since the toothed ring is meshed with the gear, the toothed ring rotates along with the gear. Under the restriction of the orbital plate member and the orbital notch, the linkage round bar will move towards the center of the toothed ring in the orbital notch, thereby driving the connecting plate member and the inner abutting plate member towards the tower barrel until the arc surface on the inner wall of the inner abutting plate member contacts the tower barrel and tightly abuts against the tower barrel, thus completing the fixing effect of the fixing device on the tower barrel.

[0017] Preferably, the driving mechanism further includes an anti - detachment ring groove, an anti - detachment round ring, a transfer ring groove, and a transfer round ring. The anti - detachment ring groove is opened inside the peripheral ring member. The anti - detachment round ring is slidably fitted in the anti - detachment ring groove.

The transfer round ring is slidably fitted in the transfer ring groove, and the right side of the transfer round ring is connected to the anti - detachment round ring. The left side of the transfer round ring is connected to the toothed ring, which restricts the toothed ring while not affecting its rotation, enabling the toothed ring to be stably located on the left side of the peripheral ring member.

[0018] Preferably, the driving mechanism further includes a driving motor, a transmission shaft, and a gear. The driving motor is fixedly connected to the right side of the support plate member through positioning bolts. The right end of the transmission shaft is connected to the output end on the left side of the driving motor. The gear is meshed with the bottom end of the toothed ring and is located on the left side of the support plate member. The left end of the transmission shaft penetrates through the support plate member and is connected to the middle part on the right side of the gear. The driving motor drives the transmission shaft to rotate, driving the gear to rotate.

[0019] Preferably, the support mechanism further includes an arc - shaped rod member and an assembly plate member. The arc - shaped rod member and the assembly plate member are both symmetrically arranged on the front and rear sides of the support plate member. The inner wall of the arc - shaped rod member is connected to the outer wall of the peripheral ring member. The assembly plate member is connected to the bottom end of the arc - shaped rod member and is fixedly connected to the support plate member through positioning bolts, strengthening the stability of the peripheral ring member on the top of the support plate member;

[0020] On both the left and right sides of the support plate member, first - level strengthening plate members are symmetrically connected in the front - and - rear directions, and the bottom surface of the first - level strengthening plate member is flush with the bottom surface of the support plate member. First - level reinforcing ribs are symmetrically connected to the top end of the first - level strengthening plate member in the front - and - rear directions, and the first - level reinforcing ribs are connected to the support plate member;

[0021] The front and back of the support plate are symmetrically connected with secondary reinforcement plates, and the bottom surface of the secondary reinforcement plates is flush with the bottom surface of the support plate. The top of the secondary reinforcement plates is symmetrically connected with secondary reinforcing ribs on the left and right, and the secondary reinforcing ribs are connected to the support plate;

[0022] Both the primary reinforcement plate and the secondary reinforcement plate are fixed to the installation ship through positioning bolts. Through the primary reinforcement plate and the secondary reinforcement plate, the stability of the support plate on the installation ship is enhanced.

[0023] Preferably, an arc-shaped notch is formed in the middle of the arc-shaped surface on the right side of the top of the support plate. An arc-shaped connecting rod is arranged in the arc-shaped notch. Rolling rings are equidistantly sleeved on the outer wall of the arc-shaped connecting rod, and the inner wall of the rolling ring is slidably matched with the outer wall of the arc-shaped connecting rod to accommodate the rolling rings and ensure the support of the support plate for the tower barrel;

[0024] Positioning rings are symmetrically arranged on both sides of the rolling ring, and the positioning rings are sleeved and connected to the outer wall of the arc-shaped connecting rod. While not affecting the rotation of the rolling ring, the rolling ring is restricted to prevent the rolling ring from concentrating in the middle of the arc-shaped connecting rod under the action of gravity;

[0025] An installation notch is formed in the support plate, and a hydraulic cylinder is embedded in the installation notch. The output end at the top of the hydraulic cylinder is connected with a longitudinal plate. The longitudinal plate is located in the arc-shaped notch. Vertical rods are symmetrically connected to the front and back of the top of the longitudinal plate, and the top ends of the vertical rods are connected to the arc-shaped connecting rod. The hydraulic cylinder drives the arc-shaped connecting rod and the rolling rings to rise and fall;

[0026] An induction notch is formed in the support plate, and the induction notch communicates with the bottom end of the arc-shaped notch. A contact switch is embedded in the induction notch. The output end of the hydraulic cylinder drives the longitudinal plate, the vertical rods and the arc-shaped connecting rod to descend until the bottom surface of the longitudinal plate contacts the contact switch. At this time, the tower barrel descends to fit with the arc-shaped surface on the right side of the top of the support plate. The support plate supports the tower barrel, and the contact switch transmits a signal to an external device terminal. The external device terminal receives the signal and controls the driving motor to start.

[0027] Preferably, a fixing method for a tower barrel fixing device of an offshore wind power installation ship includes the following steps:

[0028] Step 1: Start the hydraulic cylinder to drive the output end of the hydraulic cylinder to drive the longitudinal plate, the vertical rods and the arc-shaped connecting rod to rise until the rolling rings protrude from the arc-shaped notch. Lift the tower barrel by a hoisting device and place it on the rolling rings. Through the rolling effect of the rolling rings on the outer wall of the arc-shaped connecting rod, it is convenient for the tower barrel to pass between the inner abutting plates in the fixing device, thereby completing the setting of the fixing device outside the tower barrel and enabling the tower barrel to pass through multiple fixing devices in sequence;

[0029] Step 2: Activate the hydraulic cylinder again, causing the output end of the hydraulic cylinder to drive the longitudinal plate, vertical rod, and arc connecting rod to descend until the bottom surface of the longitudinal plate contacts the contact switch. At this time, the tower barrel descends to fit against the arc surface on the right side of the top of the support plate, and the tower barrel is supported by the support plate. The contact switch transmits a signal to the peripheral terminal.

[0030] Step 3: The peripheral terminal receives the signal and controls the driving motor to start. The driving motor drives the transmission shaft to rotate, driving the gear to rotate. Since the gear ring is meshed with the gear, the gear ring rotates with the gear. Under the restriction of the track plate and the track notch, the linkage round rod will move towards the center of the gear ring in the track notch, thereby driving the connecting plate and the inner pressing plate towards the tower barrel until the arc surface on the inner wall of the inner pressing plate contacts the tower barrel and presses against the tower barrel, thus completing the fixing effect of the fixing device on the tower barrel.

[0031] Step 4: The arc surface on the inner wall of the feedback pressing plate presses against the tower barrel as the arc surface on the inner wall of the inner pressing plate presses against the tower barrel. During the movement of the installation ship, if the tower barrel undergoes left - right translation, the feedback pressing plate will translate with the tower barrel under the action of friction. Among them, the signal emitted by the photoelectric emitter is received by the receiver directly below. When the feedback pressing plate translates, the receiver shifts and cannot receive the signal emitted by the photoelectric emitter. At this time, the receiver transmits the data to the peripheral terminal, and the peripheral terminal receives the data, thus facilitating the timely reflection of the situation of the tower barrel deviation.

[0032] Compared with the prior art, the beneficial effects of the present invention are:

[0033] The present invention uses multiple such fixing devices to support the outside of the tower barrel and internally fix the tower barrel through multiple inner pressing plates. While completing the fixation of the tower barrel, through the photoelectric emitter and reflector in the monitoring mechanism, when the feedback pressing plate translates, the receiver transmits the data to the peripheral terminal, and the peripheral terminal receives the data, thus facilitating the timely reflection of the situation of the tower barrel deviation, thereby completing the real - time monitoring of the fixed state of the tower barrel for personnel to understand in a timely manner.

[0076] Embodiment 2: Please refer to Figures 1 - 14 As shown, a fixing method for a tower barrel fixing device of an offshore wind power installation ship includes the following steps:

[0077] Step 1: Start the hydraulic cylinder 5012 to drive the output end of the hydraulic cylinder 5012 to drive the longitudinal plate member 5013, the vertically arranged rods 5014 and the arc connecting rod 509 to rise until the rolling ring 5010 protrudes from the arc notch 508. Lift the tower barrel 10 by a hoisting device and place it on the rolling ring 5010. Due to the rolling effect of the rolling ring 5010 on the outer wall of the arc connecting rod 509, it is convenient for the tower barrel 10 to pass between the inner pressing plate members 201 in the fixing device, thereby completing the setting of the fixing device outside the tower barrel 10, and enabling the tower barrel 10 to pass through multiple fixing devices in sequence;

[0078] Step 2: Start the hydraulic cylinder 5012 again to drive the output end of the hydraulic cylinder 5012 to drive the longitudinal plate member 5013, the vertically arranged rods 5014 and the arc connecting rod 509 to descend until the bottom surface of the longitudinal plate member 5013 contacts the contact switch. At this time, the tower barrel 10 descends to fit against the arc surface on the right side of the top of the support plate member 501. The tower barrel 10 is supported by the support plate member 501, and the contact switch transmits a signal to an external device terminal;

[0079] Step 3: The peripheral terminal receives the signal and controls the driving motor 409 to start. The driving motor 409 drives the transmission shaft 4010 to rotate, driving the gear 4011 to rotate. Since the gear ring 401 is meshed with the gear 4011, the gear ring 401 rotates with the gear 4011. Under the restriction of the track plate member 402 and the track notch 403, the linkage round bar 404 will move towards the center of the gear ring 401 in the track notch 403, thereby driving the connecting plate member 205 and the inner abutting plate member 201 towards the tower barrel 10 until the arc surface on the inner wall of the inner abutting plate member 201 contacts the tower barrel 10 and abuts against the tower barrel 10, thus completing the fixing effect of the fixing device on the tower barrel 10;

[0080] Step 4: The arc surface on the inner wall of the feedback abutting plate 302 abuts as the arc surface on the inner wall of the inner abutting plate member 201 abuts against the tower barrel 10. During the movement of the installation ship, if the tower barrel 10 undergoes left - right translation, the feedback abutting plate 302 will translate with the tower barrel 10 under the action of friction. Among them, the signal emitted by the photoelectric emitter 304 is received by the receiver 306 directly below. When the feedback abutting plate 302 translates, the receiver 306 deviates and cannot receive the signal emitted by the photoelectric emitter 304. At this time, the receiver 306 transmits the data to the peripheral terminal, and the peripheral terminal receives the data, thus facilitating the timely reflection of the situation where the tower barrel 10 deviates.

[0081] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
