DETAILED DESCRIPTION

[0023] In order to make the utility model's purpose, technical scheme and advantage more clearly, the utility model will be further described below in combination with the drawings.

[0024] In the embodiment, referring to Figures 1-5 The high-sensitivity forest protection terminal box based on the composite one-way airflow structure comprises a box body 1, a one-way airflow hole 2 array is arranged on the side plate of the box body 1 as an airflow inlet, an airflow outlet is arranged on the bottom plate of the box body 1, and a flue gas detection device is placed in the box body 1.

[0025] The one-way airflow hole 2 comprises an air inlet 21, an airflow duct 22, a cavity 23 and an air outlet 24, the air inlet 21 is a pipe-shaped structure with a diameter gradually decreasing, the air inlet 21 is connected with one end of the airflow duct 22, the air outlet 24 is arranged at the other end of the airflow duct 22, the air outlet 24 is a pipe-shaped structure with a diameter gradually decreasing, and the cavity 23 is arranged at the connection position of the airflow duct 22 and the air outlet 24.

[0026] The airflow outlet is composed of a plurality of rectangular holes 3 arranged in an array.

[0027] For the design of the one-way airflow hole 2, as shown in Figure 3 and Figure 4 A cylindrical structure is adopted, and the structure is left-right symmetrical. Figure 3 The black arrows in the figure represent the direction of the airflow, the area of the air inlet 21 is relatively larger, and the airflow duct 22 is relatively smaller. There is a cavity 23 on the edge of the protrusion in the figure, and the external airflow can normally enter the internal equipment, but the internal airflow is relatively difficult to flow out due to the relatively smaller air outlet 24. The existence of the cavity 23 will cause the existence of backflow, and the backflow is relatively small compared with the internal airflow, thereby playing a hindering role. The external smoke and other airflows enter the internal equipment from the side wall of the equipment, and due to the limitation of the composite one-way airflow structure, the airflows are beneficial to enter but hinder the internal airflows from flowing out from the side and the front hole. In addition, the smoke particles have a certain weight, and therefore flow out from the rectangular holes 3 at the bottom of the equipment. The design can facilitate the smoke and other airflows to enter the internal equipment, and when smoke appears, the smoke in the internal equipment is effectively accumulated, thereby making it easier for the smoke sensor and other modules to monitor the change of the environment. The measurement sensitivity of the forest protection intelligent terminal is also increased.

Different components are placed in the partition plate 42, for example, the battery used for placing the flue gas detection device is placed below the partition plate 42, and the remaining devices used for placing the flue gas detection device are placed above the partition plate 42.

[0029] Preferred, such as Figure 6 As shown, longitudinal slots 5 are provided on opposite side walls inside the housing 1, and the internal fixing plate 4 is inserted into the corresponding slots 5 on both sides.

[0030] As an optimization of the above embodiments, such as Figure 1 As shown, a fixing hole 6 is provided on the outside of the box 1 to fix the terminal box to an external object, such as hanging it on a tree trunk.
