DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-Figure 5 A photovoltaic power transformer installation construction structure includes a connecting plate 1 and a connecting plate 2. The connecting plate 1 and the connecting plate 2 are at the same horizontal position, and the outer ends of the two are both provided with arc-shaped openings, which are adapted to the outer wall of the electric pole. The lower side wall of the connecting plate 1 is fixedly provided with a baffle 1 3 and a baffle 2 4 which are parallel to each other. The ends of the baffle 1 3 and the baffle 2 4 both extend rightward from the connecting plate 1. The baffle 1 3 and the baffle 2 4 form a sliding track. The lower side wall of the connecting plate 2 is fixedly connected with a slider 5 which is slidably provided between the baffle 1 3 and the baffle 2 4. A horizontal left-facing support plate 6 is fixedly provided on the upper side wall of plate 2, and a mounting plate 7 is fixedly provided on the upper side wall of the support plate 6. A plurality of positioning holes are provided on the mounting plate 7, and the positioning holes correspond to the positioning holes on the transformer. The transformer can be fixedly connected to the upper side of the mounting plate 7 by a plurality of fastening bolts. A vertical downward clamping plate 8 and a vertical downward clamping plate 9 are fixedly provided on the lower side walls of connecting plate 1 and connecting plate 2, respectively. The clamping plate 1 8 and the vertical downward clamping plate 9 are arranged in an arc shape. The clamping plate 1 8 and the vertical downward clamping plate 9 are used to fit the outer wall of the pole, and the mounting plate 7 is fixed at a certain height by friction.

[0021] The card plate 1 8 and the card plate 2 9 correspond to the arc-shaped openings on the connecting plate 1 and the connecting plate 2 2 respectively. A friction mechanism is arranged between the card plate 1 8 and the connecting plate 1. The upper and lower sides of the card plate 1 8 and the card plate 2 9 are provided with retaining rings 10. The retaining ring 10 includes an annular retaining ring and two fastening bolts for fastening the annular retaining ring. When the card plate 1 8 and the card plate 2 9 are attached to the electric pole, the retaining rings 10 are fixedly sleeved on the electric pole respectively, and the corresponding retaining rings 10 are respectively located at the lower ends of the card plate 1 8 and the card plate 2 9 and the upper ends of the connecting plate 1 and the connecting plate 2 2, so that the card plate 1 8 and the card plate 2 9 are fixed between the two retaining rings 10, thereby improving the stability of the entire installation structure.

[0022] The left end portion of the support plate 6 is slidably arranged on the upper side wall of the connecting plate 1, and the outer side wall of the left end of the support plate 6 is fixedly connected with a sleeve 11, and the upper side wall of the connecting plate 1 is fixedly provided with a sleeve 2 12 corresponding to the sleeve 11 and located on the left side of the sleeve 11, the inner walls of the sleeve 11 and the sleeve 2 12 are smooth, and a threaded rod 13 is movably inserted between the sleeve 11 and the sleeve 2 12, and two ends of the threaded rod 13 are respectively sleeved with two nuts 14 located on the inner sides of the sleeve 11 and the sleeve 2 12, when the two nuts 14 squeeze the opposite side walls of the sleeve 11 and the sleeve 2 12 respectively, due to the limiting effect of the nut 14, the support plate 6 will not be able to slide to the left on the connecting plate 1, so that by adjusting the relative position of the nut 14 on the threaded rod 13, the connecting plate 1 and the connecting plate 2 2 respectively drive the card plate 1 8 and the card plate 2 9 to fit with the outer wall of the electric pole.

[0023] The friction mechanism includes a notch 15 opened in the middle of the outer wall of the card plate 18 and a rotating seat 16 fixed on the lower side wall of the connecting plate 1. The rotating seat 16 is rotatably connected with a rotating plate 17. The end of the rotating plate 17 is located in the notch 15. The left ends of the baffle 13 and the baffle 24 are fixedly connected with a fixed plate 18. A spring 19 is fixedly connected between the fixed plate 18 and the rotating plate 17. Under the elastic action of the spring 19, the end of the rotating plate 17 extends into the notch 15 on the card plate 18, and the connecting plate 22 is moved so that the card plate 18 and the card plate 29 are fitted with the corresponding outer wall of the electric pole. At this time, the rotating plate 17 deflects to the right by a certain angle, and the spring 19 is compressed. Initially, the card plate 18 and the card plate 29 are in contact with the ground, and the mounting plate 7 is also at the near-ground end, which is convenient for workers to install and fix the transformer on the ground. After the transformer is installed, the crane is enabled to fix the lifting rope to the lifting rings on the connecting plate 1 and the connecting plate 2 (not shown in the figure). The crane lifts the connecting plate 1 and the connecting plate 2 together with the transformer to a predetermined height of the electric pole. During the rising process, the outer wall of the electric pole continuously squeezes the rotating plate 17, and the notch 15 has enough space to make the lower end of the rotating plate 17 deflect to the right. When the lifting rope is released, the transformer is pressed down, so that the card plate 18 and the card plate 29 press the outer wall of the electric pole down. The end of the rotating plate 17 and the inner walls of the card plate 18 and the card plate 29 are all provided with anti-slip pads. At this time, the end of the rotating plate 17 has a tendency to deflect to the left under the action of the friction force of the outer wall of the electric pole, and the inner top wall of the notch 15 limits the outer wall of the rotating plate 17, so that the end of the rotating plate 17 is pressed against the outer wall of the electric pole, and the connecting plate 1 and the connecting plate 2 are fixed at a predetermined height. Then, a corresponding retaining ring 10 is set on the electric pole to limit the ends of the card plate 18, the card plate 29, the connecting plate 1 and the connecting plate 2, so as to improve the stability of the connecting plate 1 and the connecting plate 2.

[0024] The right ends of baffle plate 1 3 and baffle plate 2 4 are both provided with through holes, in which bolts 21 are inserted, and the end of the bolt 21 is sleeved with a nut 2 located on the outside of baffle plate 2 4, and the outer wall of the bolt 21 is movably sleeved with a pad 20 located between baffle plate 1 3 and baffle plate 2 4, and the pad 20 is clamped between baffle plate 1 3 and baffle plate 2 4, which is beneficial to improve the connection strength between baffle plate 1 3 and baffle plate 2 4 and reduce the deformation resistance of baffle plate 1 3 and baffle plate 2 4.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
