DETAILED DESCRIPTION

[0020] In order to make the application purposes, features and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the embodiments described below are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0021] Reference Figure 1 , Figure 2 and Figure 3 , an infrared laser double-light-ray induction module, comprising an induction module shell 1, the top surface of one end of the induction module shell 1 is provided with a connecting sleeve 2, the end of the connecting sleeve 2 away from the induction module shell 1 is provided with a connecting plug 3, an anti-collision rubber sleeve 4 is glued and fixed to the outer surface of the middle part of the induction module shell 1, a sealing cover plate 5 covers the top surface of the induction module shell 1, the sealing cover plate 5 extends into the induction module shell 1 and is sleeved with a lower sealing sleeve 9, the lower sealing sleeve 9 is fixed to the top surface inside the induction module shell 1, the lower sealing sleeve 9 is annular with an L-shaped section surface matched with the sealing cover plate 5, the outer surface of the sealing cover plate 5 is fixed with a fixed side plate 6, each fixed side plate 6 is fixedly connected with the induction module shell 1 through a fixing bolt 7, the top surface of the induction module shell 1 is provided with a threaded hole matched with the fixing bolt 7, the fixed side plate 6 is annular matched with the sealing cover plate 5, the bottom surface of the fixed side plate 6 is glued and fixed with a sealing rubber pad 8, and the sealing rubber pad 8 abuts against the top surface of the induction module shell 1.

[0022] Specifically, when it is necessary to open the inside of the induction module shell 1, first move the induction module shell 1 to a dry and clean environment, twist the fixing bolt 7 to release the fixing between the fixing bolt 7 and the induction module shell 1, and take out the fixing bolt 7 from the inside of the fixed side plate 6, so as to release the fixing between the sealing cover plate 5 and the induction module shell 1, take out the sealing cover plate 5 from the inside of the induction module shell 1, take out and open the output end and the input end assembled on the sealing cover plate 5 for maintenance, after the maintenance is completed, cover the sealing cover plate 5 on the induction module shell 1, and fix the fixed side plate 6 with the induction module shell 1 through the fixing bolt 7, so that the fixed side plate 6 extrudes the sealing rubber pad 8, and the sealing property of the inside of the induction module shell 1 is ensured.

[0023] As an optimization scheme, as Figure 3As shown, the outer surface of the middle part of the sealing cover plate 5 is provided with a placing groove 10, and a threaded inner tube 12 is embedded and fixed inside the sealing cover plate 5 above the placing groove 10. A breathable sleeve 11 is threadedly sleeved on the threaded inner tube 12, and a breathable mesh is fixed in the middle part of the breathable sleeve 11. The height of the breathable sleeve 11 is greater than the height of the upper groove of the placing groove 10.

The placing groove 10 is filled with a drying agent, and the placing groove 10 is arranged in a ring shape matched with the sealing cover plate 5.

[0024] Specifically, before installing the sealing cover plate 5, the breathable sleeve 11 is first twisted to move upward, thereby opening the placing groove 10. The drying agent is placed in the placing groove 10, and then the breathable sleeve 11 is twisted again to move downward, thereby avoiding the exposure of the drying agent in the placing groove 10. When external gas enters the induction module shell 1 through the gap between the sealing cover plate 5 and the lower sealing sleeve 9, it first contacts the drying agent in the placing groove 10. The drying agent absorbs the moisture in the airflow, and then the airflow enters the induction module shell 1, thereby further ensuring the dryness of the induction module shell 1.
