DETAILED DESCRIPTION

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] Example:

[0024] Reference Figures 1 to 4 The utility model discloses a solar photovoltaic power supply device, comprising a column 1, the lower half of which is fixedly inserted into the ground, a plurality of connecting rods 2 are fixedly connected to the outer peripheral side of the column 1, and a placement plate 3 is fixedly connected to the ends of two corresponding connecting rods 2 away from the column 1. A side groove 4 is provided on the side of the placement plate 3 close to the column 1, and a photovoltaic panel 5 is installed on the side of the placement plate 3 away from the column 1. The photovoltaic panel 5 is fixedly connected to the placement plate 3 by bolts 6, and the bolts 6 are located in the side groove 4.

[0025] A sealing cover 7 is installed in the side groove 4 , and the sealing cover 7 completely covers the side groove 4 . A fixing part 8 is arranged in the placement plate 3 . A cavity 9 is opened in the column 1 , and a driving part 10 is arranged in the cavity 9 .

[0026] In this embodiment, the column 1 is inserted into the ground and cannot be pulled out. When the bolt 6 is loosened, the photovoltaic panel 5 will be released from the placement plate 3, and the photovoltaic panel 5 can be removed for maintenance and replacement.

[0027] In the initial state, the outer surface of the sealing cover 7 fits with the inner wall of the side groove 4, and the sealing cover 7 completely covers the side groove 4 and the bolt 6. The thief cannot see the bolt 6, and the sealing cover 7 cannot be removed due to the action of the fixing part 8. Therefore, the thief cannot remove the photovoltaic panel 5 based on his life experience, thereby improving the anti-theft effect of the photovoltaic panel 5.

[0028] In a further preferred embodiment of the present invention, Figure 2 and Figure 3 As shown, the fixing portion 8 includes a sliding groove 81 respectively opened on the upper and lower inner side walls of the side groove 4, and a first spring 82 is fixedly connected to the inner wall of the sliding groove 81. A sliding bar 83 is fixedly connected to one end of the first spring 82, and a part of the sliding bar 83 is slidably connected to the corresponding sliding groove 81. A slot 84 is opened at the side wall of the sealing cover 7 corresponding to the sliding bar 83, and the sliding bar 83 slides through the corresponding slot 84.

[0029] In this embodiment, in the initial state, the first spring 82 is in a natural state, and the sliding bar 83 passes through the locking groove 84 , so the sealing cover 7 cannot slide out of the side groove 4 .

[0030] In a further preferred embodiment of the present invention, Figure 2 As shown, the driving part 10 includes a through hole 101 opened at the top of the column 1, a vertical bar 102 is slidably connected in the cavity 9, and two connecting ropes 103 are fixedly connected to the side wall of the vertical bar 102. The connecting rope 103 slides through the column 1, the connecting rod 2 and the placement plate 3 and extends into the corresponding sliding groove 81, and the end of the connecting rope 103 away from the vertical bar 102 is fixedly connected to the corresponding sliding bar 83. A second spring 104 is fixedly connected between the bottom of the vertical bar 102 and the bottom wall of the cavity 9.

[0031] In this embodiment, in the initial state, the second spring 104 is in a natural state, and the connecting rope 103 is just straightened and is not subjected to tension. When the maintenance personnel want to disassemble the photovoltaic panel 5, a thin rod is used to insert the cavity 9 from the through hole 101. The thin rod contacts the vertical bar 102 and presses the vertical bar 102, driving the vertical bar 102 to move downward, the second spring 104 is compressed, and the connecting rope 103 pulls the corresponding sliding bar 83 out of the corresponding slot 84 and retracts into the sliding slot 81, and the first spring 82 is compressed. At this time, since the sliding bar 83 is out of the slot 84, the sealing cover 7 is no longer fixed under the action of gravity and slides out of the side groove 4, so that the bolt 6 is exposed, and the photovoltaic panel 5 can be removed by turning the bolt 6.

[0032] When installing the photovoltaic panel 5, after fixing the bolt 6, press the vertical bar 102 to make the sliding bar 83 retract into the sliding groove 81, insert the sealing cover 7, and then stop pressing the vertical bar 102. Under the action of the restoring force of the second spring 104 and the first spring 82, the sliding bar 83 is automatically inserted into the slot 84, completing the fixation of the sealing cover 7.

[0033] In a further preferred embodiment of the present invention, Figure 2 As shown, the height of the column 1 is 2.0 to 2.2 m.

[0034] In this embodiment, the height of the column 1 is set to 2.0-2.2 m, which is higher than the height of an average person. Therefore, thieves cannot see the existence of the through hole 101, further improving the anti-theft security of the device. Moreover, maintenance personnel can generally touch the through hole 101 by raising their hands, so maintenance personnel do not need climbing tools such as ladders, which facilitates maintenance work for maintenance personnel.

[0035] In a further preferred embodiment of the present invention, Figure 4 As shown, the two opposite side walls of the vertical bar 102 are provided with an escape path 11 , and the connecting rope 103 is fixedly connected in the escape path 11 .

[0036] In this embodiment, the portion of the connecting rope 103 located in the cavity 9 is completely within the avoidance path 11 , so when the vertical bar 102 moves downward, the connecting rope 103 will not be squeezed between the vertical bar 102 and the inner wall of the cavity 9 .

[0037] In a further preferred embodiment of the present invention, Figure 2 As shown, a plurality of drain ports 12 are provided in the upper half of the outer circumference of the column 1. When the second spring 104 is in a natural state, the drain ports 12 are at the same height as the top surface of the vertical bar 102.

[0038] In this embodiment, the vertical bar 102 is slidably connected to the cavity 9 , so rainwater enters the cavity 9 through the through hole 101 and is blocked by the vertical bar 102 , and is discharged through the drain port 12 without accumulating in the cavity 9 .

[0039] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
