DETAILED DESCRIPTION

[0048] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0049] Please refer to Figures 1-8 The present application provides a technical solution: a marine wind power pile verticality automatic detection device, comprising a frame 1,

[0050] The gravity ball 11 is installed on the top of the frame 1 through a traction structure, and the gravity ball 11 is vertically downward under the action of gravity;

[0051] The conical tray 12 is connected with the frame 1 through an elastic structure, and a ball hole 14 is formed in the center of the conical tray 12; the conical tray 12 can rotate around the ball center of the ball hole 14;

[0052] A limiter is used to limit the conical tray 12 and is fixed with the frame 1;

[0053] The supporting cap 13 is used to lift the gravity ball 11 and slowly descend through a driving assembly, so that the bottom of the gravity ball 11 is suspended above the conical tray 12, the gravity ball 11 swings and presses the conical tray 12, and the conical tray 12 is inclined to the inclination direction of the wind power pile;

[0054] The trigger is used to release the position limiter of the conical tray 12, so that the conical tray 12 rises and the ball hole 14 forms a spherical hinge structure with the cap 13;

[0055] Before installation, the gravity ball 11 is lifted by the cap 13, so that the gravity ball 11 is out of the suspended state, and the gravity ball 11 is lowered to reduce the shaking during transportation and installation, so as to prevent the gravity ball 11 from being damaged by impact and affecting the sensitivity and accuracy of the device; the position limiter limits the conical tray 12, so that the elastic structure is in a force storage state;

[0056] When installing, first connect the frame 1 with the wind power pile (which can be connected by welding or flange), drive the assembly to lower the cap 13, and the gravity ball 11 on the cap 13 will also be lowered; when the gravity ball 11 is about to be separated from the cap 13 (i.e. when the pressure exerted by the gravity ball 11 on the cap 13 is 0), the cap 13 continues to descend by a certain distance, so that the gravity ball 11 can swing (the distance between the gravity ball 11 and the cap 13 is related to the sensitivity of the verticality detection device, and the sensitivity of the detection device can be adjusted by adjusting the distance between them); at the same time, the trigger releases the position limiter of the conical tray 12, and the elastic structure in the force storage state pushes the conical tray 12 upward; when the ball hole 14 at the center of the conical tray 12 contacts the cap 13, the conical tray 12 is stopped from rising by the cap 13, and the cap 13 and the ball hole 14 form a spherical hinge structure (i.e. the conical tray 12 can rotate around the cap 13), at this time, the distance between the gravity ball 11 and the conical tray 12 is constant, which can ensure that the gravity ball 11 swings at the same angle, and the conical tray 12 tilts at the same angle, thereby ensuring the accuracy and sensitivity of the verticality detection device;

[0057] During use, when the wind power pile is tilted, the frame 1 is fixed with the wind power pile, so the frame 1 drives the conical tray 12 to tilt, and the gravity ball 11 remains vertical and downward under the action of gravity; the side wall of the conical tray 12 contacts the gravity ball 11, so that the conical tray 12 tilts relative to the frame 1, and the tilting direction of the conical tray 12 is the tilting direction of the wind power pile, thereby realizing the detection of the verticality of the wind power pile; in addition, the combination of the gravity ball 11 and the conical tray 12 can detect any tilting direction of the wind power pile, which is convenient for maintenance personnel to make targeted maintenance solutions.

[0058] In summary, the gravity ensures that the gravity ball 11 is always in a vertical downward state; when the wind power pile is tilted, the gravity ball 11 presses the conical tray 12, so that the conical tray 12 tilts in the tilting direction of the wind power pile, thereby realizing the detection of the verticality of the wind power pile; in addition, the combination of the gravity ball 11 and the conical tray 12 can detect any tilting direction of the wind power pile, which is convenient for maintenance personnel to make targeted maintenance solutions.

[0059] In the present application, the gravity ball 11 is slowly released by the cap 13, when the gravity ball 11 is balanced, the cap 13 continues to descend by a distance, so that the gravity ball 11 can swing, the trigger releases the position limiter of the conical tray 12, the elastic structure in the force storage state pushes the conical tray 12 upward, the conical tray 12 contacts the cap 13 to stop rising, at this time, the distance between the gravity ball 11 and the conical tray 12 is constant, without considering the displacement and fatigue strength improvement problem in the process of part transportation, the same swinging angle of the gravity ball 11 can ensure the same inclination angle of the conical tray 12, thereby ensuring the accuracy and sensitivity of the verticality detection device.

[0064] When the conical tray 12 is inclined, the conical tray 12 first contacts the sliding rheostat 21, and the inclination angle of the wind power pile at this time is set as a critical angle, the conical tray 12 continues to incline, an alarm is sent to the control center through the external signal transmitter, and the sensing spring 23 can play a buffering role;

[0065] The electric telescopic rod 22 is retracted to drive the sliding rheostat 21 to rise until the sliding rheostat 21 is completely separated from the conical tray 12, and the rising distance of the electric telescopic rod 22 is the actual inclination angle of the wind power pile.

[0069] As a further scheme of the present application, the driving assembly comprises

[0070] The supporting rod 41 is fixedly arranged with the supporting cap 13;

[0071] The movable sleeve 43 and the driven wheel 44 are slidably arranged through the key, and the movable sleeve 43 is threadedly connected with the supporting rod 41;

[0072] The driving motor 45 is provided with the driving wheel 46 on the output shaft, and the driving wheel 46 is engaged with the driven wheel 44;

[0077] The trigger spring 54 is fixedly arranged between the movable sleeve 43 and the driven wheel 44;

[0078] Referring to Figure 5 、 Figure 6As the gravity ball 11 descends, the pressure exerted by the gravity ball 11 on the cap 13 gradually decreases. The trigger spring 54 gradually pushes the movable sleeve 43 upward. The limit spring 34 drives the slide rod 32 to move in the direction of the axis of the conical tray 12. The slide rod 32 drives the wedge driven block 53 to squeeze the wedge driven block 52 through the connecting frame. The wedge locking block 31 disengages from the conical tray 12, so that when the gravity ball 11 is about to disengage from the cap 13, the conical tray 12 can rise, completing the installation and debugging of the verticality detection device and ensuring the sensitivity of the verticality detection device.

[0084] See Figure 2 , Figure 3 As the gravity ball 11 descends, the traction rope 61 gradually tauts. When the traction rope 61 tauts, the traction spring 63 is gradually compressed. When the elastic force of the traction spring 63 equals the weight of the gravity ball 11, the gravity ball 11 is about to detach from the support cap 13. On the one hand, the traction spring 63 can drag the gravity ball 11 through the traction rope 61, which can reduce the friction when the gravity ball 11 contacts the conical tray 12, thereby reducing the wear of the conical tray 12 and improving the sensitivity and service life of the verticality detection device. On the other hand, the pre-tightening structure can apply a pre-tightening force to the traction spring 63, reducing the swaying of the gravity ball 11 before installation and reducing the risk of impact.
