DETAILED DESCRIPTION

[0025] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figures 1 to 4As shown, the offshore wind power foundation pedestal stability detection equipment provided in this embodiment includes a frame 3 and a first driving mechanism, the first driving mechanism includes a body and a driving end capable of reciprocating close to / away from the body, the body is fixed to the frame 3; in the direction away from the body, the driving end is sequentially fixed with a protective component 5 and a first impact component 6; projected along the movement direction of the driving end, the outer contour projection of the first impact component 6 is located in the projection area of ​​the protective component 5, so that the protective component 5 can prevent the waste generated when the first impact component 6 contacts the foundation pedestal from moving toward the body.

[0027] Compared with the prior art, the offshore wind power foundation pedestal stability detection equipment provided in this embodiment has a frame 3 used to fix and support the body of the first driving mechanism, and the first impact component 6 is driven by the driving end of the first driving mechanism to make a reciprocating motion, thereby performing a contact impact on the foundation pedestal, and the protective component 5 is used to shield the splashing waste generated when the first impact component 6 contacts the foundation pedestal, thereby reducing the probability of the waste pedestal posing a danger to the life safety of the operator and improving the safety of the equipment operator.

[0028] In this embodiment, the first driving mechanism includes a telescopic cylinder 4 , a fixed end of the telescopic cylinder 4 is connected to the frame 3 , and a movable end of the telescopic cylinder 4 is fixedly connected to the first impact assembly 6 .

[0029] Specifically, the device also includes a base 1, two telescopic cylinders 4, the fixed ends of the two telescopic cylinders 4 are fixedly connected to the base 1, the frame 3 is arranged below the telescopic cylinder 4 and fixedly connected to the bottom end of the telescopic cylinder 4, the base 1 is arranged on one side of the telescopic cylinder 4 and fixedly connected to the side of the telescopic cylinder 4, the piston rod of the telescopic cylinder 4 is connected to the first impact assembly 6, and the base support can be impacted or contacted under the drive of the telescopic cylinder 4 to detect its stability.

[0030] It should be noted that the offshore wind power foundation pedestal stability detection equipment also includes a handle 2, which is arranged on the top of the base 1 to facilitate the operator to perform detection operations.

[0031] The first impact assembly 6 may specifically include a fixed plate 61, an elastic member and a first impact plate 63; the fixed plate 61 is fixedly connected to the driving end of the first driving mechanism, the first impact plate 63 is arranged on a side of the fixed plate 61 away from the first driving mechanism, and the elastic member is arranged between the fixed plate 61 and the first impact plate 63.

[0032] In this embodiment, the elastic member is a shock absorbing spring 62. One end of the shock absorbing spring 62 is connected to the fixed plate 61, and the other end is connected to the first impact plate 63, so as to alleviate the impact of the first impact plate 63 on the telescopic cylinder 4 when the force is applied to the telescopic cylinder 4, thereby protecting the service life of the telescopic cylinder 4. Specifically, there are multiple shock absorbing springs 62, and the multiple shock absorbing springs 62 are arranged at intervals between the fixed plate 61 and the first impact plate 63. Preferably, the multiple shock absorbing springs 62 are evenly distributed between the fixed plate 61 and the first impact plate 63, so that the force applied to the first impact plate 63 can be evenly absorbed by the shock absorbing springs 62.

[0033] Specifically, the first impact plate 63 is driven by the piston rod of the telescopic cylinder 4 to directly contact and collide with the base platform. The front end of the first impact plate 63 is firstly in direct contact with the base platform and receives the reaction force from the base platform. When the reaction force reaches the evenly distributed shock-absorbing spring 62, it will be absorbed by the evenly distributed shock-absorbing spring 62. The shock-absorbing spring 62 transfers the damped force to the fixed plate 61, and then the fixed plate 61 transfers the remaining reaction force to the piston rod of the telescopic cylinder 4, which greatly reduces the reaction force from the outside, enhances the service life of the telescopic cylinder 4, and reduces the vibration and other problems caused by the reaction force.

[0034] In this embodiment, a fixing screw hole 64 is provided on the side of the first impact plate 63 away from the base 1, and the fixing screw hole 64 is used to connect with external accessories. For example, when the size specification of the first impact plate 63 is not suitable, an impact plate of other size specifications can be connected in the fixing screw hole 64 so that the impact plate can meet the requirements of the corresponding foundation platform.

[0035] The protection component 5 specifically includes a protection plate 50 , a protection frame 51 is provided on the outer circumference of the protection plate 50 , and a connecting groove 52 is provided on the protection plate 50 , and the connecting groove 52 is used for fixed connection with the circumference of the first impact component 6 .

[0036] Specifically, the connection groove 52 is provided in the middle of the protection plate 50, and the inner surface of the connection groove 52 is fixedly connected to the outer circumference of the fixing plate 61 of the first impact assembly 6. In this embodiment, a protection frame 51 is provided on the outer circumference of the protection plate 50, and the protection frame 51 extends in a direction away from the base 1, further preventing the waste from splashing in the direction of the base 1, reducing the probability of the splashing waste reaching the base 1, and at the same time, the waste blocked by the protection assembly 5 has its splashing force reduced to a certain extent, and its lethality is reduced.

[0037] It should be noted that the size specifications of the protection frame 51 are larger than the size specifications of the first impact plate 63. Since the protection plate 50 is arranged on the circumference of the fixed plate 61, relative to the first impact plate 63, in the plane perpendicular to the telescopic direction of the telescopic cylinder 4, the overall projection area of ​​the protection plate 50 is larger than the projection area of ​​the first impact plate 63. Therefore, it is possible to protect the waste generated when the first impact plate 63 hits the foundation platform.

[0038] In this embodiment, the overall structure of the protection component 5 is relatively simple and does not affect the normal function of the overall equipment. At the same time, its own use cost and subsequent maintenance and replacement cost are also low, and it can give full play to its own protection function.

[0039] The offshore wind power foundation pedestal stability detection equipment also includes a second impact component 53 and a second driving mechanism. The second impact component 53 is connected to the protective plate 50 . The second driving mechanism is used to adjust the distance between the second impact component 53 and the protective component 5 .

[0040] The second impact component 53 is arranged on the side of the protective plate 50 away from the first driving mechanism; when projected along the movement direction of the driving end of the first driving mechanism, the outer contour projection of the second impact component 53 is located in the projection area of ​​the protective component 5, and the outer contour projections of the first impact component 6 and the second impact component 6 do not overlap and have a gap.

[0041] Preferably, the second driving mechanism includes a grip rod 531, a turntable 532 and a screw rod 533; a screw hole is provided on the protective plate 50, and the screw rod 533 is installed in the screw hole. One end of the screw rod 533 facing the first driving mechanism is connected to the center of the turntable 532, the grip rod 531 is connected to the side of the turntable 532 away from the screw rod 533, and the extension direction of the grip rod 531 is parallel to the extension direction of the screw rod 533, and the end of the screw rod 533 away from the first driving mechanism is connected to the impact assembly.

[0042] In this embodiment, the impact assembly includes a second impact plate 535 and a buffer pad 534 ; one end of the buffer pad 534 is connected to the second impact plate 535 , and the other end of the buffer pad 534 is connected to the screw rod 533 .

[0043] In the offshore wind power foundation pedestal stability detection equipment provided in this embodiment, the second impact assembly 53 is installed on the protective plate 50, and the outer contour projection of the second impact assembly 53 is located in the projection area of ​​the protective assembly 5 along the motion direction of the driving end of the first driving mechanism, and the outer contour projections of the first impact assembly 6 and the second impact assembly 6 do not overlap, and there is a gap, that is, according to the position observed during specific use, the second impact assembly 53 is spaced apart from the first impact assembly 6 in the vertical direction. In actual use, when the first impact plate 63 cannot impact the foundation pedestal at a higher position or its contact area is insufficient, the second impact assembly 53 arranged above the first impact assembly 6 can be used to contact the foundation pedestal at that location to increase the operating range of the equipment.

[0044] Specifically, the gripping rod 531 can be held and the turntable 532 can be rotated, thereby driving the screw rod 533 to rotate relative to the protective plate 50, thereby driving the second impact plate 535 and the buffer pad 534 to move horizontally relative to the protective plate 50, and then the second impact plate 535 stops after reaching the required use position. At this time, under the cooperation of the screw rod 533 and the screw hole, the second impact plate 535 is fixed here, and then the second impact plate 535 can impact the base support platform under the drive of the telescopic cylinder 4. At the same time, when the second impact plate 535 is in direct contact with the base support platform, because the buffer pad 534 is arranged between the second impact plate 535 and the screw rod 533, the second impact plate 535 will transfer force to the buffer pad 534 when receiving external impact, and the buffer pad 534 absorbs and reduces the impact force and then transmits it to the next link, thereby reducing the external impact force of the protective plate 50.

[0045] The offshore wind power foundation pedestal stability detection equipment provided in this embodiment adopts the second impact component 53 to extend the overall use height, so that the foundation pedestal at a higher place can be detected when in use. At the same time, when the contact area of ​​the first impact plate 63 itself is insufficient, the second impact plate 535 of the second impact component 53 serves to increase the contact area, and the second driving mechanism adjusts its own position through the screw rod 533 when in use, and has high flexibility in use.

[0046] At the same time, the buffer pad 534 is used to reduce the impact force from the second impact plate 535, and the impact force from the first impact plate 63 is absorbed by the evenly distributed shock-absorbing spring 62, thereby reducing the impact force transmitted to the telescopic cylinder 4, greatly extending the service life of the telescopic cylinder 4, and reducing the impact of high-intensity impact force on the piston rod.

[0047] In summary, the offshore wind power foundation pedestal stability detection device provided by the present invention includes a frame 3 and a first driving mechanism, the first driving mechanism includes a body and a driving end capable of reciprocating close to / away from the body, the body is fixed to the frame 3; in the direction away from the body, the driving end is sequentially fixed with a protective component 5 and a first impact component 6; along the direction of movement of the driving end, the outer contour projection of the first impact component 6 is located in the projection area of ​​the protective component 5, so that the protective component 5 can block the waste debris generated when the first impact component 6 contacts the foundation pedestal from moving toward the body. Compared with the prior art, the offshore wind power foundation pedestal stability detection device provided by the present invention uses the first impact component 6 to contact and impact the foundation pedestal under the drive of the first driving mechanism, and shields the splashing waste debris generated when the first impact component 6 contacts the foundation pedestal through the protective component 5, reducing the probability of the waste debris causing danger to the life safety of the operator and improving the safety of the equipment operator.
