DETAILED DESCRIPTION

[0024] The embodiments of the present application will be further described in detail below with reference to the drawings and examples. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0025] As shown in the accompanying Figure 1 , the accompanying Figure 2 , the accompanying Figure 3 , the accompanying Figure 4 and the accompanying Figure 5 :

[0026] Embodiment one: the present application provides a kind of self-heating snow removal photovoltaic module, comprising:

[0027] Photovoltaic panel body 1, photovoltaic panel body 1 includes shell 101, several photovoltaic panel modules 102 are installed in the inside of shell 101, and the upper end of photovoltaic panel module 102 is provided with tempered glass layer 103;

[0028] Temperature sensor 2, temperature sensor 2 is installed in the inside of shell 101, temperature sensor 2 is distributed between photovoltaic panel module 102, and electric heating plate 3 is installed in the inside of shell 101 at the rear end of photovoltaic panel module 102, and controller 10 is installed at the rear end of shell 101;

[0029] Eaves sealing plate 5, eaves sealing plate 5 is installed at the bottom of shell 101, the bottom of eaves sealing plate 5 is connected with hinge shaft 7, the bottom of hinge shaft 7 is connected with water guide plate 6, and several adjusting mechanisms 8 are installed at the rear end of shell 101, and adjusting mechanism 8 is rotatably connected with water guide plate 6 through connecting rod 9.

[0030] As can be known from the above, in use, the temperature of the surface of tempered glass layer 103 is detected by using temperature sensor 2 at different positions, and the temperature signal is transmitted to controller 10, when the temperature is lower than the threshold value set by controller 10, controller 10 automatically starts electric heating plate 3, and the heat generated by electric heating plate 3 is transmitted to the surface of tempered glass layer 103 through photovoltaic panel module 102, so that the accumulated snow is melted by heat, when the temperature sensor 2 at a certain place in the inside of photovoltaic panel body 1 detects that the temperature returns to normal, controller 10 controls the corresponding position electric heating plate 3 to stop heating, and the energy consumption is reduced;

[0031] The melted snow flows along the surface of the tempered glass layer 103 to the surface of the fascia board 5, and the snow is guided and discharged by the fascia board 5. In the process of discharging, the controller 10 starts the adjusting mechanism 8. In the process of energized operation of the adjusting mechanism 8, the output end drives the connecting rod 9 to move. In the process of movement and deformation of the connecting rod 9, the water guide plate 6 rotates and deforms around the hinge shaft 7 to adjust. The deformed water guide plate 6 can guide the snow discharged by the fascia board 5 for the second time, change the discharge location of the snow, avoid the harm of ice cones caused by the long-time discharge of the melted snow in a certain place to the photovoltaic panel body 1, and improve the drainage effect of the device.

[0032] The temperature on the photovoltaic panel body 1 can be automatically detected during use by the temperature sensor 2 and the electric heating plate 3. When the snow on the photovoltaic panel body 1 causes the temperature to decrease, the controller 10 automatically starts the electric heating plate 3. The heat generated by the electric heating plate 3 is transmitted to the surface of the tempered glass layer 103 through the photovoltaic panel module 102, so that the accumulated snow is heated and melted. When the temperature sensor 2 at a certain position in the photovoltaic panel body 1 detects that the temperature returns to normal, the controller 10 controls the electric heating plate 3 at the corresponding position to stop heating, thereby reducing energy consumption.

[0033] As shown in Figs. 1 and 2, the device comprises a photovoltaic panel body 1, a temperature sensor 2, an electric heating plate 3, a controller 10, a water guide plate 6, a connecting rod 9, an adjusting mechanism 8, and a housing 101. Figure 3 and Figs. 3 and 4: Figure 4

[0034] Specifically, regarding the above-mentioned adjusting mechanism 8, the adjusting mechanism 8 comprises a mounting seat 802 mounted at the rear end of the housing 101. An electric push rod 801 is mounted in the mounting seat 802. The output end of the electric push rod 801 is connected with a female joint 803, and the female joint 803 is rotationally connected with the connecting rod 9.

[0035] Preferably, the number of adjusting mechanisms 8 is four, and the adjusting mechanism 8 is electrically connected with the controller 10.

[0036] As can be seen from the above, in use, the electric push rod 801 is assembled at the rear end of the housing 101 by the mounting seat 802. After assembly, a stress point is provided for the adjustment of the electric push rod 801. In the process of energized operation of the electric push rod 801, the output end drives the female joint 803 to move. In the process of movement of the female joint 803, the connecting rod 9 is driven to move and adjust, so as to change the angle of the water guide plate 6.

[0037] As shown in Figs. 3 and 4: Figure 2

[0038] Specifically, regarding the above-mentioned temperature sensor 2, a heat insulation strip is mounted at the rear end of the temperature sensor 2. The heat insulation strip is distributed between adjacent electric heating plates 3.

[0039] Preferably, the temperature sensor 2 is distributed at the corner between adjacent photovoltaic panel modules 102. ​​

[0040] As can be seen from the above, the heat barrier at the rear end of the temperature sensor 2 can block the heat emitted by the electric heating plate 3 during use, reducing the impact of the electric heating plate 3 on the detection of the temperature sensor 2 during heating, and making the detection of the temperature sensor 2 more accurate.

[0041] The working principle of the embodiment is: in use, the temperature sensors 2 at different positions detect the temperature of the surface of the tempered glass layer 103 and transmit the temperature signal to the controller 10. When the temperature is lower than the threshold set by the controller 10, the controller 10 automatically starts the electric heating plate 3, and the heat generated by the electric heating plate 3 is transmitted to the surface of the tempered glass layer 103 through the photovoltaic panel module 102, so that the accumulated snow is heated and melted;

[0042] The melted snow flows along the surface of the tempered glass layer 103 to the surface of the cornice board 5, and the cornice board 5 guides and discharges the snow. In the process of discharging, the controller 10 starts the adjusting mechanism 8, and in the process of energizing the adjusting mechanism 8, the output end drives the connecting rod 9 to move. In the process of moving and deforming the connecting rod 9, the water guide plate 6 rotates and deforms around the hinge shaft 7 to adjust. The deformed water guide plate 6 can guide the snow discharged by the cornice board 5 again, changing the discharge location of the snow. When the temperature sensor 2 at a certain position in the photovoltaic panel body 1 detects that the temperature returns to normal, the controller 10 controls the corresponding electric heating plate 3 to stop heating, reducing energy consumption.

[0043] As shown in Figs. 1-4, Figure 1 , Figs. 5-8, Figure 3 and Figs. 9-12, Figure 5

[0044] Embodiment two: this embodiment is basically the same as the previous embodiment, the difference is:

[0045] The rear end of the photovoltaic panel body 1 is provided with a plurality of connecting mechanisms 4.

[0046] The connecting mechanism 4 comprises a connecting table 401 installed at the rear end of the shell 101, and a connecting seat 402 rotatably connected to the rear end of the connecting table 401.

[0047] The connecting seat 402 is provided with a through hole.

[0048] As can be seen from the above, the connecting table 401 is connected between the shell 101 by bolts, and the connecting seat 402 is connected between the external structure to realize the support of the photovoltaic panel body 1. In the process of installation, the connecting seat 402 is rotated to adjust the assembly according to the shape of the external structure. The bolts are connected between the external structure through the through hole, so that the photovoltaic panel body 1 is more stable and the use process is optimized.

[0049] As shown in Figs. 1-4,​Figure 5 As shown:

[0050] In this embodiment, the difference from the above two embodiments is that:

[0051] The sealing batten 5 is provided with a plurality of water guide grooves 11.

[0052] As can be seen from the above, by providing the sealing batten 5 with a plurality of water guide grooves 11, the snow water flowing from the photovoltaic panel body 1 to the surface of the sealing batten 5 can be guided and discharged in a branched manner in use, so as to facilitate centralized treatment of the water.
