Description

Technical Field

[0001] The present invention belongs to the technical field of forest fire warning, and specifically relates to a forest fire warning device based on digital video analysis. Background Art

[0002] Since forests appeared on the earth, forest fires have accompanied them. Forest fires not only burn and injure trees, directly reducing the forest area, but also seriously damage the forest structure and forest environment, resulting in the imbalance of the forest ecosystem, the decline of forest biomass, the weakening of productivity, the reduction of beneficial animals and birds, and even causing casualties to humans and livestock. Forest fires directly threaten the healthy development of the ecological environment in the region and even globally and the safety guarantee of social property.

[0003] However, the existing forest fire warning often takes pictures of the entire forest through a camera. When a large fire occurs during the shooting, the camera will be transmitted to the control station through a specific program to prompt the staff. However, often when the transmission is completed, the camera is still exposed outside, so it is easily damaged in a high-temperature environment.

[0004] In view of this, the present invention is specifically proposed. Summary of the Invention

[0005] To solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0006] A forest fire warning device based on digital video analysis, including a lower turntable and an upper turntable, the lower turntable and the upper turntable are symmetrical to each other, a first arc plate and a second arc plate are arranged above the upper turntable, and two symmetrically arranged support rods are arranged above the lower turntable, and the support rods are used to lift the upper turntable.

[0007] As a preferred embodiment of the present invention, a support frame is rotatably arranged at the bottom of the lower turntable, a cavity is opened in the support frame, and a servo motor is arranged in the cavity, and a rotating rod is fixedly installed at the output end of the servo motor, and the end of the rotating rod away from the servo motor is fixedly connected to the lower turntable.

[0008] As a preferred embodiment of the present invention, an installation block is further arranged in the middle above the lower turntable, a placement table is arranged on one side wall of the installation block, and a camera body is placed in the placement table.

[0009] As a preferred embodiment of the present invention, a circular chute is opened above the lower turntable, a plurality of moving sliders arranged in a circumferential distribution are slidably arranged in the inner cavity of the circular chute, and a telescopic rod is arranged above each moving slider, and the other end of the telescopic rod is arranged at the bottom of the upper turntable.

[0010] As a preferred embodiment of the present invention, a protective housing is further provided at the bottom of the upper turntable.

[0011] As a preferred embodiment of the present invention, inclined surfaces are provided on both the first arc-shaped plate and the second arc-shaped plate, and arc-shaped chutes are provided on the inclined surfaces. The two arc-shaped chutes are symmetrical to each other. Guide sliders are slidably provided in the inner cavities of the two arc-shaped chutes, and support rods are provided at the bottoms of the two guide sliders.

[0012] The present invention has the following beneficial effects compared with the prior art:

[0013] In the present invention, when the servo motor operates, it can drive the rotating rod to rotate. When the rotating rod rotates, it can drive the upper turntable to rotate. When the lower turntable rotates, it can drive the support rod to rotate. Since the upper parts of the support rods are respectively connected to the guide sliders slidably provided on the first arc-shaped plate and the second arc-shaped plate, when the support rod rotates, it can drive the guide slider to move in the arc-shaped chute. And because the inclined surfaces of the first arc-shaped plate and the second arc-shaped plate are inclined, the upper turntable can be driven to move upward. When the upper turntable moves upward, it can drive the protective housing to move vertically upward, so that the protective housing leaves the camera body. Since the camera body is placed in the placement table and the placement table can rotate, it is ensured that the camera body can rotate to monitor the forest.

[0014] In the present invention, when a fire occurs, the camera body will monitor and transmit this information through a processor, etc. At the same time, it can also control the servo motor to stop operating. Therefore, the upper turntable can move downward under the action of gravity, so as to ensure that the protective housing can be reset to protect the placed camera body.

[0015] The following further describes the specific embodiments of the present invention in detail with reference to the drawings. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manner

[0022] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0023] As Figures 1 to 4 shown, a forest fire warning device based on digital video analysis includes a lower turntable 2 and an upper turntable 6. The lower turntable 2 and the upper turntable 6 are symmetric to each other. Above the upper turntable 6, there are a first arc plate 8 and a second arc plate 9. Above the lower turntable 2, there are two symmetric support rods 12. The support rods 12 are used to lift the upper turntable 6. When the servo motor 16 operates, it can drive the rotating rod 17 to rotate. When the rotating rod 17 rotates, it can drive the upper turntable 6 to rotate. When the lower turntable 2 rotates, it can drive the support rods 12 to rotate. Since the upper parts of the support rods 12 are respectively connected to the guiding sliders 11 slidably arranged on the first arc plate 8 and the second arc plate 9, when the support rods 12 rotate, they can drive the guiding sliders 11 to move in the arc chute 10. And because the inclined surfaces of the first arc plate 8 and the second arc plate 9 are inclined, the upper turntable 6 can be driven to move upward. When the upper turntable 6 moves upward, it can drive the protective housing 7 to move vertically upward, so that the protective housing 7 moves away from the camera body 15. Since the camera body 15 is placed in the placing table 14 and the placing table 14 can rotate, it is ensured that the camera body 15 can rotate to monitor the forest.

[0024] In the detailed implementation manner, a support frame 1 is rotatably arranged at the bottom of the lower turntable 2. A cavity is opened in the support frame 1, and a servo motor 16 is arranged in the cavity. The output end of the servo motor 16 is fixedly installed with a rotating rod 17. The end of the rotating rod 17 away from the servo motor 16 is fixedly connected to the lower turntable 2. In this setting, it is ensured that the lower turntable 2 can rotate.

[0025] Furthermore, a mounting block 13 is also arranged in the middle above the lower turntable 2. A placing table 14 is arranged on one side wall of the mounting block 13. The camera body 15 is placed in the placing table 14. In this setting, the installation position and components of the camera body 15 are determined.

[0026] Furthermore, a circular chute 3 is provided above the lower turntable 2. A plurality of moving sliders 4 arranged in a circular distribution are slidably disposed in the inner cavity of the circular chute 3. An expansion rod 5 is provided above each moving slider 4, and the other end of the expansion rod 5 is disposed at the bottom of the upper turntable 6. In this setting, it is ensured that the upper turntable 6 can move upward.

[0027] Furthermore, a protective housing 7 is also provided at the bottom of the upper turntable 6. In this setting, the installation position of the protective housing 7 is determined.

[0028] Furthermore, inclined surfaces are provided on both the first arc plate 8 and the second arc plate 9, and arc-shaped chutes 10 are provided on the inclined surfaces. The two arc-shaped chutes 10 are symmetrical to each other. Guide sliders 11 are slidably disposed in the inner cavities of the two arc-shaped chutes 10. Support rods 12 are provided at the bottoms of the two guide sliders 11. In this setting, it is ensured that when the lower turntable 2 rotates, it can drive the support rod 12 to rotate. Since the upper parts of the support rods 12 are respectively connected to the guide sliders 11 slidably disposed on the first arc plate 8 and the second arc plate 9, when the support rod 12 rotates, it can drive the guide slider 11 to move in the arc-shaped chute 10. And because the inclined surfaces of the first arc plate 8 and the second arc plate 9 are inclined, it can drive the upper turntable 6 to move upward. When the upper turntable 6 moves upward, it will be able to drive the protective housing 7 to move vertically upward.

[0029] The implementation principle of a forest fire warning device based on digital video analysis in this embodiment is as follows:

[0030] First, when using the camera body 15 for monitoring, it is driven to operate by the servo motor 16. When the servo motor 16 operates, it can drive the rotating rod 17 to rotate. When the rotating rod 17 rotates, it can drive the upper turntable 6 to rotate. When the lower turntable 2 rotates, it can drive the support rod 12 to rotate. Since the upper part of the support rod 12 is respectively connected to the guide sliders 11 slidably arranged on the first arc-shaped plate 8 and the second arc-shaped plate 9, when the support rod 12 rotates, it can drive the guide sliders 11 to move in the arc-shaped chute 10. And because the inclined surfaces of the first arc-shaped plate 8 and the second arc-shaped plate 9 are inclined, it can drive the upper turntable 6 to move upward. When the upper turntable 6 moves upward, it will drive the protective housing 7 to move vertically upward, so that the protective housing 7 leaves the camera body 15. Since the camera body 15 is placed in the placement table 14 and the placement table 14 can rotate, it is ensured that the camera body 15 can rotate to monitor the forest. When a fire occurs, the camera body 15 will transmit this information through a processor, etc., and at the same time, it can also control the servo motor 16 to stop operating. Therefore, the upper turntable 6 can move downward under the action of gravity, so as to ensure that the protective housing 7 can be reset to protect the placed camera body 15 (where the signal transmission of the camera body 15 is prior art).
