A push rod 16 is provided at the bottom of the extended end of the cover plate 5, and a limiting slide groove adapted to the push rod 16 is provided on the inclined surface, so that when the driving telescopic rod 9 changes from the extended state to the retracted state, the cover plate 5 and the push rod 16 are driven to descend. When the push rod 16 descends to the end of the push rod 16 away from the bottom of the cover plate 5 and extends into the corresponding limiting slide groove, as the push rod 16 continues to descend, the push rod 16 slides along the limiting slide groove, thereby pushing the protection groove 10 to slide to cover the display screen 8;

[0041] In the above technical solution, the protection box 3 is provided with a protection groove 10 on the side wall of the display screen 8, and the sliding connection method is preferably in the form of a pulley or a slide groove. The protection groove 10 is used to protect the display screen 8. Specifically: the display screen 8 and the protection groove 10 are both square and are both arranged along the length direction of the protection box 3. The sliding direction of the protection groove 10 is consistent with the length direction of the protection box 3. The side wall of one end of the protection groove 10 along its sliding direction is provided with a slide-out hole 11.

When the display screen 8 is in the protection groove 10, the protection groove 10 completely covers the display screen 8;

[0042] An auxiliary block 12 is provided on the top of the protection groove 10, and the top surface of the auxiliary block 12 is an inclined surface, and the high end of the inclined surface is close to the slide-out hole 11, that is, the low end of the inclined surface is far away from the slide-out hole 11; a pair of support rods 14 are horizontally provided on the side wall of the protection box 3 away from the mounting rod 2, and the pair of support rods 14 are arranged at different heights, and one end of the pair of support rods 14 away from the protection box 3 is connected with a mounting plate 13, that is, the mounting plate 13 is connected to the protection box 3 through a pair of support rods 14, and one end of the mounting plate 13 away from the pair of support rods 14 extends to the side where the protection groove 10 is located, and the mounting plate 13 A pair of springs 15 are arranged on the top, and the pair of springs 15 are arranged up and down. One end of the spring 15 located at a high position is connected to the mounting plate 13, and the other end is connected to the side wall of the auxiliary block 12 near it. One end of the spring 15 located at a low position is connected to the mounting plate 13, and the other end is connected to the side wall of the protective groove 10 near it. The pair of springs 15 are located on both sides of the slide-out hole 11 to avoid interference with the sliding of the protective groove 10; when the pair of springs 15 are in a natural state, the display screen 8 is exposed to the environment, and the protective groove 10 is located on the side of the display screen 8 close to the mounting rod 2; it should be noted that Figure 6 The mounting plate 13 is not shown;

[0043] One end of the cover plate 5 close to the auxiliary block 12 extends toward the auxiliary block 12 to cover the auxiliary block 12 (the covering means that the projection of the extended part on the horizontal plane can cover the projection of the auxiliary block 12 on the horizontal plane), and a push rod 16 is provided at the bottom of the extended part of the cover plate 5, and the push rod 16 is adapted to the inclined surface (the bottom surface of the push rod 16 can be designed to be an inclined surface matching the inclined surface, which helps the push rod 16 to slide along the inclined surface). When the push rod 16 contacts the inclined surface, the push rod 16 continues to descend, which can push the protective groove 10 to slide, thereby exposing / covering the display screen 8;

[0044] In this technical solution, when in use, in the initial state, the cover plate 5 is located above the protection box 3, the air quality sensor 6 and the noise sensor 7 are exposed to the environment to monitor the air quality and noise of the environment, and at the same time, a pair of springs 15 are in a natural state to pop open the protection groove 10 to expose the display screen 8 to the environment to display the monitored environmental data; when encountering bad weather, the telescopic rod 9 is started to drive the cover plate 5, the air quality sensor 6, and the noise sensor 7 to descend into the protection box 3, and during the process of the cover plate 5 descending, the push rod 16 is driven to descend, and the push rod 16 descends to contact with the inclined surface When the push rod 16 is touched, as the push rod 16 continues to descend, the push rod 16 slides along the inclined surface, thereby driving the protection groove 10 to slide toward the mounting plate 13. When the cover plate 5 is covered on the protection box 3, the protection groove 10 completely covers the display screen 8 therein, thereby protecting the display screen 8. When the weather improves, the telescopic rod 9 can be started again to drive the cover plate 5, the air quality sensor 6, and the noise sensor 7 to extend out of the protection box 3 synchronously, and the monitoring work can be carried out normally. While the telescopic rod 9 is extended, the protection groove 10 is extended in the direction away from the mounting plate 13 under the rebound action of a pair of springs 15, thereby opening the display screen 8.

[0045] The beneficial effect obtained by adopting this technical solution is that, by arranging the protective groove 10, the slide-out hole 11, the auxiliary block 12, the mounting plate 13, the spring 15, the push rod 16, and the limiting slide groove, a structure for protecting the air quality sensor 6, the noise sensor 7 and the display screen 8 is provided, which can minimize the damage of the above-mentioned components under severe weather conditions.
