[0021] The following will be combined with the embodiments to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.

[0022] See Figure 1-Figure 2 , the utility model provides a technical solution:

[0023] A photoelectric drying indicator device includes a drying cylinder 1, a breathable sheet 2, a fixing ring 3, a transparent plate 4, and a locking ring 5. The breathable sheet 2 is fixedly provided on one end of the drying cylinder 1, and the fixing ring 3 is fixedly provided on the outer wall of the other end of the drying cylinder 1. A mounting hole 6 is provided on the end of the drying cylinder 1, and a locking ring 5 is sealed on the inner wall of the mounting hole 6. The locking ring 5 is provided with a through-hole 7, and the transparent plate 4 is sealed on the observation hole 7. The locking ring 5 and the fixing ring 3 are arranged on the same end of the drying cylinder 1. The drying cylinder 1 is used to store a drying indicator. The breathable sheet 2 is a breathable steel sheet in the prior art. Moisture in the photoelectric device is absorbed by the drying indicator through the breathable steel sheet. The transparent plate 4 is a conventional glass plate. Changes in the drying indicator can be observed through the transparent plate 4, and the drying indicator can be replaced immediately. The drying cylinder 1 and the locking ring 5 are detachably sealed. The drying indicator can be replaced by disassembling the locking ring 5. The fixing ring 3 is sealed and fixedly connected to the drying cylinder 1. The function of the fixing ring 3 is to seal and fix the entire device on the photoelectric device.

[0024] In some embodiments, the inner wall of the mounting hole 6 is provided with an internal thread, and the outer wall of the locking ring 5 is provided with an external thread that matches the internal thread. The drying cylinder 1 and the locking ring 5 are connected by a thread, which facilitates disassembly and assembly, and convenient replacement of the drying indicator.

[0025] In some embodiments, a compression ring 8 is sealed against the outer wall of the locking ring 5, and a sealing ring 9 is disposed between the compression ring 8 and the end of the drying cylinder 1. The compression ring 8 is provided to secure the sealing ring 9, which prevents rainwater from entering the drying cylinder 1 and causing the drying indicator to become ineffective. The end of the compression ring 8 is flush with the end of the locking ring 5.

[0026] In some embodiments, an inner groove 10 is provided on the end of the drying cylinder 1, and the outer end of the compression ring 8 is disposed in the inner groove 10. The inner groove 10 is provided for mounting the compression ring 8 so that part of the compression ring 8 is located inside the drying cylinder 1, which makes the structure and appearance of the entire device more beautiful.

[0027] In some embodiments, a mounting groove 11 for mounting a sealing ring is provided between the fixing ring 3 and the outer wall of the drying cylinder 1. The mounting groove 11 is provided for mounting the sealing ring, thereby achieving a better seal between the device and the photovoltaic device and preventing rainwater from entering the interior of the photovoltaic device.

[0028] In some embodiments, the fixing ring 3 is provided with at least two locking holes 12. The locking holes 12 are provided to secure the entire device to the photovoltaic device to be dried. Generally, at least two locking holes 12 are provided, evenly spaced, and secured to the photovoltaic device via bolts. To provide a tighter connection between the device and the photovoltaic device, six locking holes 12 are evenly spaced.

[0029] In some embodiments, the inner wall of the drying cylinder 1 is connected to the mounting hole 6 via a tapered surface 13. The cross-sections of the drying cylinder 1 and the mounting hole 6 are both circular and coaxially arranged, with the inner wall of the drying cylinder 1 and the mounting hole 6 connected via the tapered surface. The tapered surface 13 is provided to facilitate replacement of the drying indicator, making it easier to pour out the drying indicator from the drying cylinder 1.

[0030] In some embodiments, the drying cylinder 1 and the air-permeable sheet 2 are fixedly connected by screws or adhesive bonding. The air-permeable sheet 2 is fixed to the end of the drying cylinder 1 and only needs to be fixed together to prevent the desiccant from leaking. Sealing is not required. Therefore, screws can be used to fix the air-permeable sheet 2 to the drying cylinder 1. Alternatively, glue can be used to bond the drying cylinder 1 and the air-permeable sheet 2 together.
