[0030] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0031] like Figures 1 to 6As shown, the movable installation platform for a floating offshore photovoltaic platform according to an embodiment of the present invention includes a first support plate 1, a second support plate 2, a first drive assembly 3, a positioning assembly 4 and a moving unit 5. The first support plate 1 and the second support plate 2 are sequentially arranged along the front-to-back direction. The first drive assembly 3 is respectively connected to the first support plate 1 and the second support plate 2 and is used to drive the first support plate 1 to move relative to the second support plate 2 along the front-to-back direction. The positioning assemblies 4 are arranged in pairs and at least two pairs are respectively provided on the first support plate 1 and the second support plate 2 along the front-to-back direction. The positioning assembly 4 includes a guide plate 41 and a clamping plate 42. The guide plate 41 is arranged along the upper The first support plate 1 or the second support plate 2 is provided with an adjustable downward position, the clamping plate 42 is provided below the first support plate 1 or the second support plate 2 and is connected to the guide plate 41, the clamping plate 42 is adjustable in the left and right directions, the clamping plate 42 is used to clamp the crossbeam or longitudinal beam fixed to the mounting frame for fixing the corresponding first support plate 1 or the second support plate 2 to the mounting frame, a plurality of mobile units 5 are provided and corresponding positioning components 4 are respectively provided on the first support plate 1 and the second support plate 2, at least part of the mobile units 5 are located below the first support plate 1 and the second support plate 2, and the mobile units 5 are used to support the crossbeam or longitudinal beam of the mounting frame.

[0032] When the movable installation platform for a floating offshore photovoltaic platform according to an embodiment of the present invention is in use, the movable installation platform is hoisted as a whole onto the installation frame, and the two positioning assemblies 4 arranged in pairs correspond to the two cross beams or the two longitudinal beams respectively, so that the moving unit 5 is supported on the corresponding two cross beams or longitudinal beams, and the moving unit 5 makes the first support plate 1 and the second support plate 2 have a set spacing with the cross beams and the longitudinal beams, and the positioning assembly 4 on the first support plate 1 is adjusted, and the guide plate 41 is moved in the up and down direction so that the guide plate 41 is located on both sides of the corresponding cross beam or longitudinal beam, and the clamping plate 42 on the guide plate 41 is adjusted, and the clamping plate 42 clamps the cross beam or longitudinal beam fixed to the installation frame body to fix the first support plate 1 to the installation frame body, and the above steps are repeated to adjust the positioning assembly 4 on the second support plate 2 to fix the first support plate 1 to the installation frame body. The second support plate 2 is fixedly connected to the mounting frame. When the movable mounting platform is moved as a whole, the connection between the clamping plate 42 on the first support plate 1 or the second support plate 2 and the crossbeam or the longitudinal beam can be released, and the first driving assembly 3 is used to drive the first support plate 1 or the second support plate 2 to move relative to the mounting frame. During the movement of the first support plate 1 or the second support plate 2, the guide plate 41 can constrain the moving direction. When the guide plate 41 encounters an obstruction from the longitudinal beam or the longitudinal beam, the guide plate 41 can be moved upward so that the clamping plate 42 is located between the crossbeam and the first support plate 1 to ensure the continuity of the movement of the first support plate 1. When the first support plate 1 is moved into place, the first support plate 1 is fixed to the crossbeam or the longitudinal beam, and the above steps are repeated to move the second support plate 2, so that the first support plate 1 and the second support plate 2 are spliced ​​to form a mounting platform.

[0033] The movable installation platform for a floating offshore photovoltaic platform according to an embodiment of the present invention can move on the photovoltaic platform and provide a support platform for workers to perform photovoltaic panel operations, thereby ensuring the number of photovoltaic panels installed and the safety of workers during operation, and greatly improving the installation efficiency of photovoltaic panels and reducing construction costs.

[0034] It should be noted that the top surface and bottom surface of the first support plate 1 are flush with the top surface and bottom surface of the second support plate 2 respectively, and the distance from the bottom of the movable unit 5 to the first support plate 1 or the second support plate 2 is greater than the sum of the dimensions of the clamping plate 42 in the up and down directions and the dimensions of the guide plate 41 located on the side of the clamping plate 42 away from the first support plate 1.

[0035] Optionally, the moving unit 5 is a roller, and a plurality of rollers are rotatably arranged on the first support plate 1 and the second support plate 2 respectively. The rotating shaft of the roller can be arranged below the first support plate 1, or above the first support plate 1, or inside the first support plate 1. When the rotating shaft of the roller is arranged above the first support plate 1 or inside the first support plate 1, a mounting groove for the roller to pass through is provided on the first support plate 1, and the first driving component 3 is an electric hydraulic push rod.

[0036] In some embodiments, Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, the guide plate 41 is U-shaped and includes a first vertical section 411, a horizontal section 412 and a second vertical section 413. The first vertical section 411 and the second vertical section 413 are vertically penetrated through the first support plate 1 or the second support plate 2 and slidably cooperate with the first support plate 1 or the second support plate 2. The horizontal section 412 is parallel to the first support plate 1 and the second support plate 2. The positioning assembly 4 includes a second drive assembly 43, which is connected to the horizontal section 412 and is used to drive the guide plate 41 to move in the up and down directions.

[0037] By setting the guide plate 41 to be U-shaped, it can be ensured that when the first support plate 1 or the second support plate 2 moves, the guide plate 41 is clamped on both sides of the crossbeam or the longitudinal beam, so as to constrain the moving direction of the first support plate 1 and the second support plate 2, avoid the mobile unit 5 from detaching from the crossbeam or the longitudinal beam, and improve the safety during use. The second driving component 43 can be used to facilitate the adjustment of the relative height of the guide rod relative to the first support plate 1 or the second support plate 2, and avoid the guide plate 41 from interfering with the longitudinal beam or the crossbeam during the process of following the movement of the first support plate 1 or the second support plate 2.

[0038] In some embodiments, Figure 4As shown, the second driving assembly 43 includes a driving motor 431 and a driving screw 432. The driving motor 431 is arranged on the first support plate 1 or the second support plate 2 corresponding to the guide plate 41. The driving screw 432 is fixed to the output shaft connected to the driving rod. The driving screw 432 passes through the horizontal section 412 and is threadedly connected to the horizontal section 412.

[0039] The driving motor 431 rotates to drive the driving screw 432 to rotate. The first vertical section 411 and the second vertical section 413 are plugged into the first support plate 1 or the second support plate 2. The driving screw 432 rotates to drive the horizontal section 412 to move in the up and down directions, which is convenient for adjusting the position of the guide plate 41 and easy to operate.

[0040] In some embodiments, Figure 4 As shown, a through hole 4111 is provided at one end of the first vertical section 411 away from the horizontal section 412, and the clamping plate 42 is slidably penetrated at one end of the second vertical section 413 away from the horizontal section 412 and is used to be plugged into the through hole 4111. A third driving component 44 is provided on the second vertical section 413, and the third driving component 44 is used to drive the clamping plate 42 to move in the left and right directions. When the clamping plate 42 is fixed to the cross beam or the longitudinal beam, the guide plate 41 moves downward relative to the first support plate 1, so that the through hole 4111 and the clamping plate 42 are located at the corresponding cross beam. Or below the longitudinal beam, the third driving assembly 44 drives the clamping plate 42 to move towards the direction close to the through hole 4111, and makes the clamping plate 42 plug and fit in the through hole 4111. At this time, the guide plate 41 moves upward relative to the first support plate 1, and the clamping plate 42 is supported under the cross beam or longitudinal beam to jointly realize the support and fixation of the cross beam or longitudinal beam with the first support plate 1. When the clamping plate 42 releases the fixation to the cross beam or longitudinal beam, the guide plate 41 can be moved downward relative to the first support plate 1 to reset the clamping plate 42. The operation is convenient and reliable.

[0041] In some embodiments, Figure 4 As shown, the third driving component 44 is an electric hydraulic push rod, which is arranged on the side of the second vertical section 413 away from the first vertical section 411. The third driving component 44 is set as an electric hydraulic push rod, which is easy to operate. The electric hydraulic push rod is set on the side of the second vertical section 413 away from the first vertical section 411. When the guide rod moves upward, the electric hydraulic push rod can avoid interference with the cross beam or the longitudinal beam, which is convenient for streamlining the structural size.

[0043] Specifically, electric hydraulic push rods are respectively provided between the two clamping plates 42 and the corresponding first vertical section 411 and second vertical section 413. The electric hydraulic push rods drive the two clamping plates 42 to move toward each other, move the guide rods to the two sides of the corresponding cross beam or longitudinal beam, and fix the first support plate 1 or the second support plate 2 by clamping the two clamping plates 42 on both sides of the cross beam or longitudinal beam.

The first plug-in portion 21 is plugged into and matched with the first slot 11. By providing the first slot 11 and the first plug-in portion, when the first support plate 1 and the second support plate 2 are moved into place, the connection reliability between the first support plate 1 and the second support plate 2 can be increased, and the connection strength between the first support plate 1 and the second support can be increased.
