Technical Field

[0001] The utility model relates to the technical field of offshore photovoltaic installation, in particular to an offshore photovoltaic walking device. Background Art

[0002] The installation of traditional photovoltaic installation components is very difficult, requiring workers to install photovoltaic components on photovoltaic piles one by one, and the construction period is long. Especially for the installation of photovoltaic installation components on tidal flats and offshore, there are high tides and low tides, strong winds and waves in tidal flats and offshore areas respectively. Due to the special geographical environment, there are problems with the transportation and installation of photovoltaic installation components on tidal flats and offshore areas.

[0003] Some people have proposed using a transport mechanism that can move on the top of photovoltaic piles to complete the transportation and installation of photovoltaic installation components. However, since each photovoltaic pile is spaced a certain distance apart, the transport mechanism walking on the top of the photovoltaic pile is equivalent to walking on point supports, and the existing common walking mechanisms cannot walk on point supports.

[0004] Therefore, in order to solve the above problems, it is urgent to develop an offshore photovoltaic walking device that can walk on point-like supports. Utility Model Content

[0005] In order to solve the problems existing in the background technology, the utility model provides an offshore photovoltaic walking device, including an upper walking mechanism, a lifting device, and a lower walking mechanism. The lower walking mechanism is located at the lower end of the upper walking mechanism, and the lifting device is arranged on the upper walking mechanism. The lifting device has the function of moving the upper walking mechanism and the lower walking mechanism upward or downward.

[0006] Furthermore, the upper walking mechanism includes a connecting frame, an upper support frame, a middle support frame, and a lower support frame. Both ends of the connecting frame are fixedly connected to the upper support frame, both ends of the middle support frame are respectively fixedly connected to the upper support frame and the lower support frame, and one side of the connecting frame is connected to the jacking device.

[0007] Furthermore, the lower walking mechanism includes a walking body and a guide groove, and the guide groove is arranged above the walking body.

[0008] Furthermore, the guide groove is a C-shaped groove.

[0009] Furthermore, the lifting device includes a lifting mechanism, a connecting plate, and a walking device. The walking device is fixedly arranged below the connecting plate. One end of the lifting mechanism is fixedly connected to the connecting plate, and the other end is connected to the upper walking mechanism.

[0010] Furthermore, the lifting device also includes a walking wheel mechanism, and the walking wheel mechanism is fixedly arranged on the walking device.

[0011] Furthermore, the walking wheel mechanism includes a walking wheel body, a walking wheel B, and a guide wheel. The walking wheel B is longitudinally arranged on the walking wheel body, and the guide wheel is transversely arranged on the walking wheel body.

[0012] Furthermore, the walking wheel body includes an upper walking wheel body and a lower walking wheel body, the upper walking wheel body is fixedly connected to the lower walking wheel body, the walking wheel B is longitudinally arranged on the lower walking wheel body, the guide wheel is transversely arranged on the lower walking wheel body, and the upper walking wheel body is fixedly connected to the walking device.

[0013] Furthermore, the walking device includes a walking device body and walking wheels A, wherein the walking wheels A are arranged below the walking device body, and the upper part of the walking device body is fixedly connected to the lower part of the connecting plate.

[0014] Furthermore, the lifting mechanism is a worm gear lift, a hydraulic lift or an electric lift.

[0015] The utility model provides an offshore photovoltaic walking device, which has the following beneficial effects:

[0016] 1. The offshore photovoltaic walking device includes an upper walking mechanism, a lifting device, and a lower walking mechanism. The lower walking mechanism is located at the lower end of the upper walking mechanism, and the lifting device is arranged on the upper walking mechanism. This device utilizes the alternating movement of the upper walking mechanism and the lower walking mechanism to achieve continuous walking on the top of the photovoltaic pile, thereby completing the transportation and installation of the photovoltaic installation components, effectively saving the transportation and installation costs.

[0017] 2. Since the entire construction process of this walking device is on the top of the photovoltaic pile, the construction process will not be affected by the high and low tides of the mudflats and the strong winds and waves at sea, and the operation can be carried out continuously, which significantly improves the construction efficiency and construction window period.

[0018] 3. The offshore photovoltaic walking device has a walking wheel body fixedly connected to the walking device body of the walking device, and the walking wheel B and the guide wheel are arranged in the guide groove. The groove width in the guide groove is slightly larger than the diameter of the guide wheel. This arrangement can not only enable the walking wheel B to stably walk along the middle position of the guide groove and prevent the walking track of the walking wheel B from deviating, but also enable the walking wheel A to stably walk along the walking body and avoid the walking track of the walking wheel A from deviating.

[0019] 4. The offshore photovoltaic walking device has a long strip opening on the upper part of the guide groove. The width of the long strip opening is smaller than the diameter of the guide wheel and larger than the thickness of the lower body of the walking wheel. This arrangement can not only ensure that the guide wheel will not fall out of the guide groove when it is lifted, thereby achieving the technical effect of lifting the lower walking mechanism, but also enable the lower body of the walking wheel to move along this long strip opening.

[0030] Reference Figure 1-5 The present embodiment provides an offshore photovoltaic traveling device. The traveling device of the present utility model comprises an upper traveling mechanism 1, a lifting device 3, and a lower traveling mechanism 2. The lower traveling mechanism 2 is located at the lower end of the upper traveling mechanism 1. The lifting device 3 is arranged on the upper traveling mechanism 1. The lifting device 3 has the function of moving the upper traveling mechanism 1 and the lower traveling mechanism 2 upward or downward.

[0031] The working principle of this walking device is as follows: when the upper walking mechanism 1 needs to move between the tops of the photovoltaic piles, the upper walking mechanism 1 is first lifted (i.e. moved upward) by the jacking device 3 to separate the upper walking mechanism 1 from the top of the photovoltaic pile. At this time, the lower walking mechanism 2 is in contact with the top of the photovoltaic pile to support the upper walking mechanism 1 and the jacking device 3. Then, an external power source is applied to the upper walking mechanism 1 to move the upper walking mechanism 1 above the top of the photovoltaic pile until it moves to a suitable position and then the upper walking mechanism 1 is dropped (i.e. moved downward) by the jacking device 3. To the top of the photovoltaic pile; when the lower walking mechanism 2 needs to move between the tops of the photovoltaic piles, the jacking device 3 is first used to lift the lower walking mechanism 2 (i.e., move it upward) to make the lower walking mechanism 2 separate from the top of the photovoltaic pile. At this time, the upper walking mechanism 1 is in contact with the top of the photovoltaic pile, playing the role of supporting the lower walking mechanism 2 and the jacking device 3, and then an external power source is applied to the lower walking mechanism 2 to make the lower walking mechanism 2 move above the top of the photovoltaic pile until it moves to a suitable position, and then the jacking device 3 is used to drop the lower walking mechanism 2 (i.e., move it downward) to the top of the photovoltaic pile. Embodiment 2

[0032] like Figure 2-4This embodiment is basically the same as the first embodiment, and further, specific embodiments of the jacking device 3, the upper walking mechanism 1, and the lower walking mechanism 2 are added. The upper walking mechanism 1 includes an upper support frame 11, a middle support frame 12, a lower support frame 13, and a connecting frame 14. Both ends of the connecting frame 14 are fixedly connected to the upper support frame 11, and both ends of the middle support frame 12 are fixedly connected to the upper support frame 11 and the lower support frame 13 respectively. One side of the connecting frame 14 is connected to the jacking device 3.

[0033] The lower walking mechanism 2 includes a walking body 21 and a guide groove 22 . The guide groove 22 is arranged above the walking body 21 , and the guide groove 22 is a C-shaped groove.

[0034] The lifting device 3 includes a lifting mechanism 31, a connecting plate 32, and a walking device 33. The walking device 33 is fixedly arranged below the connecting plate 32. One end of the lifting mechanism 31 is fixedly connected to the connecting plate 32, and the other end is connected to the connecting frame 14 of the upper walking mechanism 1. The walking device 33 includes a walking device body 331 and a walking wheel A332. The walking wheel A332 is arranged below the walking device body 331. The upper part of the walking device body 331 is fixedly connected to the lower part of the connecting plate 32. The lifting mechanism 31 is a worm gear lifter, a hydraulic lifter, or an electric lifter.

[0035] The lifting device 3 also includes a walking wheel mechanism 4, which is fixedly arranged on the walking device 33. The walking wheel mechanism 4 includes a walking wheel body, a walking wheel B43, and a guide wheel 44. The walking wheel body includes an upper walking wheel body 41 and a lower walking wheel body 42. The upper walking wheel body 41 is fixedly connected to the lower walking wheel body 42. The walking wheel B43 is longitudinally arranged on the lower walking wheel body 42. The guide wheel 44 is transversely arranged on the lower walking wheel body 42. The upper walking wheel body 41 is fixedly connected to the walking device body 331 of the walking device 33. The walking wheel B43 and the guide wheel 44 are movably arranged in the guide groove 22. The groove width in the guide groove 22 is slightly larger than the diameter of the guide wheel 44. When the walking wheel B43 contacts the bottom surface of the guide groove 22, under the driving action of the external power source, the walking wheel B43 can move along the bottom surface of the guide groove 22. At this time, the guide wheel 44 plays a guiding role, so that the walking wheel B43 can move stably along the middle position of the guide groove 22 to avoid the walking trajectory of the walking wheel B43 from being offset; a long strip opening 221 is provided at the upper part of the guide groove 22, and the width of the long strip opening 221 is smaller than the diameter of the guide wheel 44 and larger than the thickness of the lower body 42 of the walking wheel. This arrangement can not only ensure that the guide wheel 44 will not fall out of the guide groove 22 when it is lifted, thereby achieving the effect of lifting the lower walking mechanism 2, but also enable the lower body 42 of the walking wheel to move along this long strip opening 221.

[0036] It should be noted that when the walking device of the utility model is working, a construction platform can be fixedly installed on the upper end of the upper support frame 11 of the upper walking mechanism 1. This construction platform is used to transport photovoltaic installation components on the one hand, and to provide a construction position for construction personnel on the other hand, so that the construction personnel can complete the installation of photovoltaic installation components. Embodiment 3

[0037] like Figure 5 This embodiment is basically the same as the second embodiment. Furthermore, a specific implementation scheme of an offshore photovoltaic walking device of the utility model is described. The specific implementation steps are as follows:

[0038] S1. Place the offshore photovoltaic walking device on the top of several photovoltaic piles in a row of photovoltaic piles, and place the photovoltaic installation components on the construction platform (the construction platform is fixedly installed on the upper end of the upper support frame 11). At this time, the lower support frame 13 of the upper walking mechanism 1 and the walking body 21 of the lower walking mechanism 2 are in contact with the top of the photovoltaic piles, and the walking wheel A332 of the walking device 33 is located on the walking body 21 of the lower walking mechanism 2, and the construction personnel stand on the construction platform;

[0039] S2, control the lifting mechanism 31 of the jacking device 3 to drive the upper walking mechanism 1 to move upward until the lower support frame 13 of the upper walking mechanism 1 is separated from the top of the photovoltaic pile. At this time, the walking body 21 of the lower walking mechanism 2 is in contact with the top of the photovoltaic pile, playing a role in supporting the upper walking mechanism 1 and the jacking device 3, and the walking wheel A332 of the walking device 33 is located on the walking body 21 of the lower walking mechanism 2;

[0040] S3, apply an external power source to the walking device 33, so that the walking wheel A332 of the walking device 33 moves toward the rear end along the walking body 21 (the rear end here refers to the end of a row of photovoltaic piles on which the photovoltaic installation components are not installed). Since the upper part of the walking device body 331 of the walking device 33 is fixedly connected to the lower part of the connecting plate 32, one end of the lifting mechanism 31 is fixedly connected to the connecting plate 32, and the other end is connected to the connecting frame 14 of the upper walking mechanism, and the walking wheel upper body 41 is fixedly connected to the walking device body 331, therefore, when the walking wheel A332 of the walking device 33 moves toward the rear end along the walking body 21 under the action of the external power source, the walking wheel B43 of the walking wheel mechanism 4 moves toward the rear end along the guide groove 22, and the upper walking mechanism 1 also moves toward the rear end until the upper walking mechanism 1 moves to the rear end of the next photovoltaic pile 5;

[0041] It should be noted that the setting of the guide wheel 44 in this step can not only enable the walking wheel B43 to move stably along the middle position of the guide groove 22 and prevent the walking track of the walking wheel B43 from deviating, but also enable the walking wheel A332 to move stably along the walking body 21 and avoid the walking track of the walking wheel A332 from deviating.

[0042] S4, controlling the lifting mechanism 31 of the jacking device 3 to drive the upper traveling mechanism 1 to move downward until the lower support frame 13 of the upper traveling mechanism 1 contacts the top of the photovoltaic pile;

[0043] S5, control the lifting mechanism 31 of the jacking device 3 to drive the walking device 33 to move upward. Since the walking wheel upper body 41 is fixedly connected to the walking device body 331 of the walking device 33, the walking wheel B43 and the guide wheel 44 of the walking wheel mechanism 4 are arranged in the guide groove 22 of the lower walking mechanism 2. Therefore, when the walking device 33 moves upward, the walking wheel B43 and the guide wheel 44 will also move upward. Because the width of the long strip opening 221 at the upper part of the guide groove 22 is smaller than the diameter of the guide wheel 44, the guide wheel 44 will drive the lower moving mechanism 2 to move upward when it is lifted, until the walking body 21 of the lower walking mechanism 2 is separated from the top of the photovoltaic pile. At this time, the lower support frame 13 of the upper walking mechanism 1 is in contact with the top of the photovoltaic pile, which plays a role in supporting the lower walking mechanism 2 and the jacking device 3;

[0044] S6, applying an external power source to the walking body 21 of the lower walking mechanism 2, so that the lower walking mechanism 2 moves toward the rear end, until the lower walking mechanism 2 also moves to the rear end of the next photovoltaic pile 5 (the rear end of the photovoltaic pile 5 referred to here is the rear end of the photovoltaic pile 5 referred to in step S3);

[0045] S7, controlling the lifting mechanism 31 of the jacking device 3 to drive the walking device 33 to move downward, thereby driving the lower walking mechanism 2 to move downward, until the walking body 21 of the lower walking mechanism 2 contacts the top of the photovoltaic pile;

[0046] S8. Construction workers install the photovoltaic installation components placed on the construction platform on the photovoltaic piles;

[0047] S9, repeat S2 to S8, so that the upper walking mechanism 1 and the lower walking mechanism 2 can walk alternately and stably on the top of the photovoltaic pile, thereby completing the transportation and installation of the photovoltaic installation components.

[0048] It should be noted that the photovoltaic installation components of the present invention refer to photovoltaic brackets, purlins, and photovoltaic panels; in addition to being able to walk on the tops of photovoltaic piles, the offshore photovoltaic walking device of the present invention can also be used in application scenarios with other point-like supports.

[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical scheme and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
