It should be noted that, without conflict, the embodiments and features in the embodiments of this application can be combined with each other.

[0020] Please refer to Figures 1-4 , the present utility model provides the following technical solutions:

[0021] A waterproof structure of a data collector, as Figures 1-3As shown in the figure, it includes a front housing 1 and a rear housing 2. One end of the front housing 1 and the rear housing 2 facing each other is open, and the two are cooperatively inserted into each other to form a chamber inside. A notch is formed on the outer ring of the joint surface where the front housing 1 and the rear housing 2 are cooperatively engaged, so that when rainwater flows in, it can be discharged downward from both sides.

[0022] A number of locking columns 11 are connected to the inner wall of the front housing 1. Specifically, the number of locking columns 11 is four, and they are distributed in a matrix on the inner cavity side wall of the front housing 1. Threaded sleeves 21 corresponding to the locking columns 11 one by one are inserted through the side wall of the rear housing 2. After the rear housing 2 and the front housing 1 are engaged with each other, bolts are passed through the threaded sleeves 21 and screwed into the locking columns 11 to lock and fix the two. A groove matching the end of the locking column 11 is provided on one side of the threaded sleeve 21 close to the locking column 11 to facilitate alignment during installation and improve the installation speed.

[0023] Among them, as Figure 2 shown, a lining plate 12 extending outward at one end is provided inside the front housing 1. The lining plate 12 has a circumferential structure parallel to the circumferential side wall of the open part of the front housing 1, and the lining plate 12 is connected to the inner wall opposite to the open part of the front housing 1. A number of support plates 13 for supporting the lining plate 12 are connected between the inner ring side wall of the front housing 1 and the side wall adjacent to the lining plate 12, and the support plates 13 are located inside the front housing 1. The number of support plates 13 is arranged at equal distances.
