[0020] In this embodiment: several BIPV photovoltaic panels 11 are installed on the roof or outer wall of the building, these areas are often idle, which can make full use of these spaces through cadmium telluride BIPV photovoltaic system 1, without occupying additional space, BIPV photovoltaic panels 11 charge energy storage battery 13 through MPPT solar controller 12 and connecting wire 16, energy storage battery 13 is connected to the normal connection of dual power supply switch 14 through connecting wire 16, AC power supply 17 is connected to the standby power supply of dual power supply switch 14, dual power supply switch 14 is connected to timing switch 15, control household appliances or household lighting, when the energy storage battery 13 is lower than 20% of the warning value, the dual power supply switch 14 will switch to the AC power supply 17, realize the power supply with the city power line, meet the daily power demand, several BIPV photovoltaic panels 11 constitute BIPV small photovoltaic building integrated power generation curtain wall, at the same time, the real-time generated electricity is connected with MPPT solar controller 12 and energy storage battery 13 through series connection, which realizes a simple off-grid power generation system, and the off-grid power generation system and cadmium telluride power generation glass supply power to household appliances or lighting equipment, several BIPV photovoltaic panels 11 are uniformly spliced and installed on the support, and the wall supports the BIPV photovoltaic panel 11 through the support. One of the BIPV photovoltaic panels 11 supports the mounting disc 4, the mounting disc 4 is connected with the wall through the contact plate 41, the contact plate 41 provides space for the rolling wheel 42 through the space gap 411, and the rolling wheel 42 rolls on the wall. When the BIPV photovoltaic panel 11 and the frame are stable on the wall, the rolling wheel 42 will not rotate due to the friction of the wall. When the equipment, support wall and the like are aged and affected by the environment wind, the BIPV photovoltaic panel 11 and the support gradually loosen with the wall. The rolling wheel 42 rolls on the wall, and the two rotary sensors 43 monitor the use state of the rolling wheel 42, so that the rotary sensor 43 can sense in time when the rolling wheel 42 rotates. The rotary sensor 43 transmits the signal to the equipment PLC control unit through wireless signal, reminding the staff to check in time and carry out maintenance, so as to avoid the continuous loosening of the BIPV photovoltaic panel 11 and the falling of the BIPV photovoltaic panel 11.

[0021] The mounting disc 4 is provided with a fixed sleeve 44 on one side, the inner wall of the fixed sleeve 44 is slidably connected with a sliding rod 45, and the contact plate 41 is rotatably connected with one end of the sliding rod 45. The mounting disc 4 supports the fixed sleeve 44, the fixed sleeve 44 supports the sliding rod 45, and the sliding rod 45 supports the contact plate 41, so that the contact plate 41 can be stably connected with the mounting disc 4. The contact plate 41 is rotatable on the sliding rod 45, so that the contact plate 41 can be adjusted in angle and flexibly respond when the BIPV photovoltaic panel 11 moves in different directions, and the sensitivity of the rolling wheel 42 and the rotary sensor 43 in use is improved.

[0022] A return spring 441 is installed on the inner wall of the fixed sleeve 44, and a limit ring 451 is installed on one end of the sliding rod 45. The limit ring 451 is slidably connected to the inner wall of the fixed sleeve 44, and one end of the return spring 441 is in contact with the limit ring 451. The fixed sleeve 44 limits the sliding rod 45 in the fixed sleeve 44 through the limit ring 451 to prevent the fixed sleeve 44 from separating from the sliding rod 45. The return spring 441 pushes the limit ring 451 so that the sliding rod 45 can drive the contact plate 41 and the rolling wheel 42 to be in close contact with the wall, ensuring the sensitive response of the rolling wheel 42 and the BIPV photovoltaic panel 11 when they move.

[0023] Several spherical rolling elements 412 are installed on one side of the contact plate 41. Each of the spherical rolling elements 412 corresponds to a vertical position of the rolling wheel 42. An anti-slip ring 421 is fixedly connected to the side wall of the rolling wheel 42. The anti-slip ring 421 increases the contact friction between the rolling wheel 42 and the wall, thereby further increasing the stability of the passive rotation of the rolling wheel 42. When the rolling wheel 42 is in a vertical state, the spherical rolling elements 412 maintain the same distance from the rolling wheel 42 and the wall. This allows the contact plate 41 to maintain stable contact with the rolling wheel 42 and the wall through the spherical rolling elements 412, reducing the impact of friction between the contact plate 41 and the wall on the detection work of the rolling wheel 42.

[0024] A pressure sensor 46 is installed inside the sliding rod 45. One end of the pressure sensor 46 is in contact with the inner wall of the fixed sleeve 44. When the fixed sleeve 44 and the sliding rod 45 extend and retract, the pressure sensor 46 is squeezed by the fixed sleeve 44, so that the pressure sensor 46 can sense the positional change between the sliding rod 45 and the fixed sleeve 44. This makes it easier for the pressure sensor 46 to sense when the BIPV photovoltaic panel 11 moves away from the wall and transmit the signal to the equipment PLC control unit to remind the staff to check and maintain it in time.

[0025] The working principle and usage process of this utility model are as follows: When the equipment, support wall, etc., age, and are affected by environmental wind, the BIPV photovoltaic panel 11 and the support wall gradually become loose. The BIPV photovoltaic panel 11 pulls the contact plate 41 according to the direction of movement, and the contact plate 41 adjusts its angle. At the same time, the rolling wheel 42 rotates using the high friction between the anti-slip ring 421 and the wall. The rotation sensor 43 monitors the usage status of the rolling wheel 42, so that the rotation sensor 43 can sense the rotation of the rolling wheel 42 in time. The rotation sensor 43 transmits the signal to the equipment PLC control unit wirelessly, reminding the staff to check and repair in time, so as to avoid the BIPV photovoltaic panel 11 from falling due to continuous loosening. At the same time, if the BIPV photovoltaic panel 11 loosens away from the wall, the fixed sleeve 44 and the sliding rod 45 extend and retract. The pressure sensor 46 can sense this in time and transmit the signal to the equipment PLC control unit to remind the staff to check and repair in time.
