[0027] During detection, the adjustment mechanism 12 adjusts the height and horizontal angle of the flaw detection mechanism 13 relative to the foundation pile of the ultra-high voltage power tower to be detected. The flaw detection mechanism 13 collects the flaw detection information of the foundation pile, and the communication mechanism 14 sends the flaw detection information to the offshore power grid control center.

[0028] During the above detection process, the adjustment mechanism 12 can adjust the position of the flaw detection mechanism 13 multiple times according to the actual situation, so as to comprehensively obtain the flaw detection information of the foundation pile of the ultra-high voltage power tower to be detected.

[0029] The present invention adjusts the flaw detection mechanism 13 from two aspects of height and horizontal angle through the adjustment mechanism 12, which can not only effectively ensure the accuracy and comprehensiveness of detection with remarkable detection effect, but also complete the whole detection process automatically without manual participation, and the detection efficiency is high.

[0030] Through the communication mechanism 14, the flaw detection information collected by the flaw detection mechanism 13 can be sent to the offshore power grid control center in time, which is convenient for the staff to obtain the pile damage information in time. It can not only effectively avoid the safety hazards existing in the on-site collection of pile damage by the staff, but also prevent the hazards caused by untimely treatment of pile damage.

[0031] Embodiment 2: Embodiment 2 is based on Embodiment 1: As Figures 1 to 7 shown, the adjustment mechanism 12 includes an angle adjustment component and a height adjustment component.

[0032] The angle adjustment component is connected to the flaw detection mechanism 13 and can drive the flaw detection mechanism 13 to rotate circumferentially relative to the pile of the ultra-high voltage tower to be detected, so as to realize the adjustment of the horizontal angle of the flaw detection mechanism 13.

[0035] As an optional implementation manner, the angle adjustment component includes a fixed arc plate 121, a movable arc plate 122 and a first driving component 123.

[0036] The arcs of the fixed arc plate 121 and the movable arc plate 122 are adapted to the pile of the ultra-high voltage tower to be detected. Both the fixed arc plate 121 and the movable arc plate 122 are formed with concave arc cavities. During detection, the pile is located in the concave arc cavities.

[0040] When adjusting the horizontal angle of the flaw detection mechanism 13, the first driving assembly 123 is started, driving the movable arc-shaped plate 122 to move along the arc-shaped guiding part, and the flaw detection mechanism 13 moves synchronously therewith, and the angle adjustment effect is remarkable.

[0041] As an optional implementation manner, the first driving assembly 123 includes a first power assembly 1231, a horizontal output gear 1232 and an arc-shaped rack 1233.

[0046] When adjusting the height of the flaw detection mechanism 13, the second driving assembly 126 is started to drive the lever 125 to swing. At this time, the movable end of the lever 125 slides along the horizontal guiding part 1242, thereby driving the lifting frame 124 to move up and down along the vertical guiding rod 111, and the angle adjustment assembly and the flaw detection mechanism 13 move up and down synchronously, and the height adjustment effect is remarkable.

[0047] The vertical guide rod 111 , the lifting frame 124 and the shifting rod 125 cooperate with each other to form a crank slider transmission mechanism, which can effectively convert the rotational action of the second driving component 126 into the lifting and reciprocating movement of the lifting frame 124 .

[0048] Specifically, the lifting frame 124 includes a horizontal lifting plate 1241, a connecting rod and a connecting plate. The horizontal lifting plate 1241 is provided with a guide hole that is matched with the shape of the vertical guide rod 111 in the vertical direction. The vertical guide rod 111 passes through the guide hole and slides with the guide hole. The connecting rod is vertically arranged on the bottom side of the horizontal lifting plate 1241 and is connected to the connecting plate. The connecting plate is fixedly connected to the fixed arc plate 121.

A retaining ring is sleeved on the end of the round pin, which has a limiting function and can be abutted against the side wall of the horizontal lifting plate 1241 to prevent the round pin from escaping from the horizontal guide groove.

[0050] As an optional embodiment, the second driving assembly 126 includes a second power assembly 1261 , a first bevel gear 1262 , and a second bevel gear 1263 .

The second bevel gear 1263 is meshed with the first bevel gear 1262.

[0053] Thus, when the second power assembly 1261 drives the first bevel gear 1262 to rotate, the second bevel gear 1263 rotates, thereby driving the shifting rod 125 to swing synchronously; the bevel gear transmission structure has a strong load-bearing capacity and a stable transmission ratio.

[0054] As an optional embodiment, the flaw detection mechanism 13 includes at least one ultrasonic flaw detector 131 .

[0055] Preferably, the number of ultrasonic flaw detectors 131 is set to two, which are respectively arranged at both ends of the movable arc plate 122.

[0061] In the actual application process, the foundation pile detection device 1 can be carried on a ship, or a support platform can be set on the electric tower, and the foundation pile detection device 1 can be fixedly arranged on the support platform.

[0063] The propulsion device 3 can provide propulsion power to make the floating body 2 travel on the sea surface. The direction control device 4 is used to control the traveling direction of the floating body 2 so that it can accurately move to the foundation pile of the ultra-high electric tower to be detected.

[0064] As an optional implementation manner, the propulsion device 3 includes a third drive assembly 31 and a drive impeller 32. A support frame 21 is arranged on the floating body 2.

[0065] The third drive assembly 31 adopts an electric drive assembly, including a third motor. The third drive assembly 31 is fixedly arranged on the support frame 21 and is drivingly connected to the drive impeller 32.

The fourth driving assembly 43 adopts an electric driving assembly and includes a fourth motor. The fourth driving assembly 43 is drivingly connected to the driving worm 42 and can drive the driving worm 42 to rotate.

[0069] When controlling the traveling direction, the fourth driving assembly 43 is started to drive the driving worm 42 to rotate, and the turbine platform 41 and the support frame 21 rotate, thereby adjusting the direction of the driving impeller 32, and thus realizing the control of the traveling direction.

[0070] The turbine platform 41 and the driving worm 42 cooperate with each other to form a worm and worm gear transmission mechanism, which has a self-locking function and makes the direction adjustment state more stable.

[0071] The working process of the automatic detection and verification device for the offshore ultra-high electric tower foundation pile is briefly described as follows: The propulsion device 3 works to make the floating body 2 approach the target electric tower foundation pile.
