[0021] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0022] Please refer to Figures 1 to 6 A bottom cable platform of an above-water photovoltaic box transformer comprises an above-water photovoltaic box transformer and a column arranged below the above-water photovoltaic box transformer (a box-type substation for photovoltaic power generation), and also comprises a horizontally arranged cross bar and a horizontally arranged longitudinal bar. The cross bar and the longitudinal bar are cross-connected, and the two ends of the longitudinal bar are connected to the column through a first clamp, and a grille is arranged above the cross bar and the longitudinal bar.

[0023] From the above description, it can be seen that the beneficial effect of the utility model is that the utility model adopts a cross-staggered cross bar and a longitudinal bar to form a bracket of the cable platform, and the bracket is fixed to the column at the bottom of the water photovoltaic box-type transformer by a first clamp, and a steel grid for placing cables is arranged above the bracket. Through the cable platform, when the photovoltaic area cable is laid near the box-type transformer platform, the bridge docking point can be flexibly selected; it can also be flexibly laid according to the final joint position of the cable in the box-type transformer; it solves the cable winding problem at the box-type transformer position, and avoids the problem that the cable head needs to be remade for later maintenance due to the failure to reserve the cable length, and the cable length is not reserved.

[0024] Furthermore, it also includes a second hoop and a reinforcement rod, the second hoop is arranged below the first hoop, and the two ends of the reinforcement rod are respectively connected to the second hoop and the longitudinal rod.

[0025] Furthermore, the reinforcement rod is an angle steel.

[0026] From the above description, it can be seen that the second clamp, the reinforcement rod and the longitudinal rod form a triangular support structure, which can enhance the structural stability.

[0027] Further, the grille is connected to the crossbars and the longitudinal bars by stainless steel tie ties.

[0028] From the above description, it can be seen that the stainless steel cable ties are simple and convenient to use and have high reliability.

[0029] Furthermore, the crossbar is welded to the longitudinal bar.

[0030] Further, the crossbar is flush with the top of the longitudinal bar.

[0031] From the above description, it can be seen that the control cross bar is flush with the top of the longitudinal bar to ensure that the steel grille is placed stably.

[0032] Furthermore, the horizontal bar is an angle steel, and the vertical bar is a channel steel.

[0033] Furthermore, the length of the horizontal rod is longer than that of the vertical rod.

[0034] From the above description, it can be seen that since the short side is the structural force connection point between the long side and the column, it is subject to greater force, so the channel steel used on the short side has better supporting force than the angle steel.

[0035] Please refer to Figures 1 to 6The first embodiment of the utility model is: a bottom cable platform of a floating photovoltaic box transformer, comprising a floating photovoltaic box transformer 1, a column 2 arranged below the floating photovoltaic box transformer 1, a horizontally arranged cross bar 3, a horizontally arranged longitudinal bar 4, a second clamp 6 and a reinforcing rod 7. The cross bar 3 and the longitudinal bar 4 are cross-staggered, the cross bar 3 is welded to the longitudinal bar 4, and the cross bar 3 is flush with the top of the longitudinal bar 4. The two ends of the longitudinal bar 4 are connected to the column 2 through the first clamp 5, and a steel grille 8 is provided above the cross bar 3 and the longitudinal bar 4, and the steel grille 8 is connected to the cross bar 3 and the longitudinal bar 4 through a stainless steel tie 9. The second clamp 6 is arranged below the first clamp 5, and the two ends of the reinforcing rod 7 are respectively connected to the second clamp 6 and the longitudinal bar 4. The first hoop 5 is composed of two semicircular rings connected head to tail, one of the two semicircular rings is connected by M20*50 high-strength bolts 10, and the other is connected by M20*90 high-strength bolts 11 and connected to the longitudinal rod 4 by M20*90 high-strength bolts 11. The first hoop 5 has the same structure as the second hoop 6. The longitudinal rod 4 is 16#A channel steel 4, the cross bar 3 is L100*6.5 angle steel, and the reinforcement rod 7 is L63*5 angle steel.

[0036] In summary, the bottom cable platform of the water photovoltaic box transformer provided by the utility model adopts a cross-staggered connection of horizontal bars 3 and vertical bars 4 to form a basic bracket, and the bracket is fixed to the column 2 at the bottom of the water photovoltaic box transformer 1 by a first clamp 5. The upper part of the bracket is connected with a stainless steel tie 9 to connect the steel grille 8 for placing the cable; a second clamp 6 is arranged below the first clamp 5, and the two ends of the reinforcement rod 7 form a triangular support structure with the second clamp 6 and the vertical bar 4 respectively to enhance the structural stability. The cable platform is simple to install, has a stable structure, and a wide range of uses. Using this cable platform, when the photovoltaic area cable is laid near the box transformer platform, the bridge docking point can be flexibly selected; it can also be flexibly laid according to the final joint position of the cable in the box transformer; it solves the problem of cable winding at the box transformer position, and avoids the problem that the cable head needs to be remade due to the failure to reserve the cable length in the later maintenance, and the cable length is not reserved.
