[0023] Various exemplary embodiments, features, and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise indicated.

[0024] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0025] In addition, numerous specific details are provided in the following specific examples to better illustrate the present application. Those skilled in the art will appreciate that the present application can be practiced without certain specific details. In some instances, methods, means, and components well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.

[0026] See also Figures 1 to 5 In an embodiment of the present invention, a device for monitoring forest and grassland fire risks includes a mounting rod 1, a humidity sensor 6, a protective box 7, a monitoring unit, a closing component, and a moving part.

[0027] For details, please refer to Figure 1 、 Figure 4 、 Figure 5 ,include;

[0028] A mounting rod 1 and a protection box 7 fixedly mounted on the mounting rod 1, wherein a chamber is formed in the protection box 7, and a monitoring unit is installed in the chamber;

[0029] It also includes a closing assembly symmetrically arranged on the protective box 7;

[0030] a moving part, installed in the chamber and connected to the monitoring unit and the closing assembly respectively;

[0031] The humidity sensor 6 is installed in the protective box 7 and establishes communication with the moving part. When the moving part controls the monitoring unit to be retracted into the protective box 7, it drives the closing component to move relative to the protective box 7 to realize the opening and closing of the protective box 7.

[0032] In detail, in this embodiment, the device for monitoring forest and grassland fire risks described in the utility model is adopted. When in use, the humidity in the air is detected by the humidity sensor 6. When the humidity in the air reaches a preset value (no fire will occur in the forest and grassland), the humidity sensor 6 sends a signal to the moving part, and the moving part works, so that the monitoring unit is retracted into the protective box 7. At the same time, the closing component is driven to move relative to the protective box 7 to realize the opening and closing of the protective box 7, thereby realizing the protection of the monitoring unit in bad weather such as rain, and avoiding short circuit and rust in the monitoring unit.

[0033] Preferably, the mounting pole 1 is fixedly mounted with a support frame 3, on which a solar panel 2 and a battery 4 are fixedly mounted, and the battery 4 is connected to the monitoring unit via an electric wire 5, and a triangular reinforcement rib is provided between the support frame 3 and the mounting pole 1, thereby improving the overall stability of the solar panel 2 and preventing the solar panel 2 from falling over in windy weather.

[0034] See also Figure 4 The monitoring unit includes a thermal imaging spectrum camera 17 slidably arranged in the protective box 7, and one end of the thermal imaging spectrum camera 17 is fixedly connected to a threaded sleeve 16.

[0035] The moving part includes a screw rod 14 rotatably installed in the protective box 7, and the screw rod 14 is driven to rotate by a motor fixedly installed in the protective box 7. The screw rod 14 is threadedly connected to the threaded sleeve 16, and the screw rod 14 is connected to the closing assembly through two sets of transmission parts.

[0036] To elaborate, when the motor receives the signal sent by the humidity sensor 6, it starts working. When the motor is working, it drives the screw rod 14 to rotate. When the screw rod 14 rotates, it drives the threaded sleeve 16 to make a linear motion along the axial direction of the screw rod 14. At the same time, the closing component is driven to work through the transmission part to achieve the driving requirements. When the threaded sleeve 16 moves, it drives the thermal imaging spectrum camera 17 to move synchronously. Among them, at least one set of second limit blocks 1701 is provided on the thermal imaging spectrum camera 17, and a second limit groove 702 is formed on the inner wall of the protective box 7 to slide with the second limit block 1701. Under the limiting action of the second limit block 1701 and the second limit groove 702, the thermal imaging spectrum camera 17 is slidably connected to the inner wall of the protective box 7. The thermal imaging spectrum camera 17 moves relative to the protective box 7 to ensure that the thermal imaging spectrum camera 17 avoids contact with external rain when it is retracted into the protective box 7, and when it is extended out of the protective box 7, the boundary of the protective box 7 is prevented from blocking the shooting work of the thermal imaging spectrum camera 17.

[0037] The transmission member includes a transmission shaft 10 rotatably installed in the protective box 7, and a gear 11 is fixedly installed on the transmission shaft 10 to cooperate with the movement of the closing component. The transmission shaft 10 is rotatably connected to a connecting shaft 13 rotatably installed in the protective box 7 through a belt 12, and the connecting shaft 13 is rotatably connected to the screw 14 through a bevel gear set 15.

[0038] See also Figure 5 The closing assembly includes a cover plate 8 slidably arranged on the protective box 7, and the cover plate 8 is formed with an embedded groove toward the center position of the protective box 7, and a rack 9 meshing with the gear 11 is provided in the embedded groove.

[0039] Furthermore, when the above-mentioned screw rod 14 rotates, it drives the symmetrically arranged connecting shafts 13 to rotate through the bevel gear set 15, so that the rotation directions of the two connecting shafts 13 are opposite. When the connecting shaft 13 rotates, the transmission shaft 10 is driven to rotate through the belt 12. When the transmission shaft 10 rotates, the gear 11 rotates synchronously. Under the meshing transmission of the gear 11 and the rack 9, the cover 8 moves relative to the protective box 7 and the movement directions of the two cover plates 8 are always opposite, so as to realize the opening and closing of the protective box 7 and prevent external rainwater from entering the protective box 7 and causing damage to the thermal imaging spectrum camera 17.

[0040] Preferably, at least one set of first limiting grooves 701 is symmetrically provided on the side of the protective box 7, and a first limiting block 801 is formed on the cover plate 8, which slides with the first limiting groove 701, wherein the first limiting block 801 is arranged in a cross-shaped structure to prevent the cover plate 8 from falling when it moves relative to the protective box 7.

[0041] It should be noted that when the cover plate 8 moves, it drives the first limit block 801 to move synchronously, and cooperates with the limiting effect of the first limit groove 701 and the first limit block 801 to achieve the sliding connection between the cover plate 8 and the protective box 7.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
