Description

Technical Field

[0001] This invention belongs to the field of forestry technology, specifically a smart forestry smoke and fire alarm device. Background Technology

[0002] With the vigorous development of afforestation, the scale of forestry in China has continued to expand, and both the forest area and the forest stock volume have shown a steady growth trend. Traditional forest fire prevention mainly relies on human patrols, but human patrols are limited by manpower and vast areas, resulting in untimely monitoring and an inability to achieve all-weather coverage. Doing a good job in forest fire prevention is not only related to the protection of forest resources, but also a prerequisite and foundation for accelerating forestry development and promoting ecological civilization construction.

[0003] Existing smoke and fire alarm devices are installed in forests, but due to their small size, the coverage area is insufficient, and when a fire occurs, the specific information of the fire cannot be confirmed in time. This leads to a slowdown in the response to fires and causes more loss of forestry resources. Therefore, a smart smoke and fire alarm device for forestry is proposed. Summary of the Invention

[0004] To address the problems mentioned in the background section, the present invention provides an intelligent forestry smoke and fire alarm device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a smart forestry smoke and fire alarm device, comprising a support base and a support column, wherein a first camera is installed at the upper end of the support column, and further comprising: The camera assembly, installed inside the support base and support column, is used to photograph the fire from a high vantage point. The balloon assembly, which is installed inside the support base and support column, is used to carry the shooting components to a high place; A blocking component, located at the top of the support column, is used to block and protect the shooting component and the balloon component; The shooting component includes a winch installed inside the support base, with a traction rope wound in the middle of the winch and a fixed rod fixedly connected to the top of the traction rope; The balloon assembly includes a helium cylinder fixedly connected inside the support base and a pair of compressed balloons placed inside the upper end of the support column. The output end of the helium cylinder is fixedly connected to a gas delivery pipe.

[0006] Preferably, a control panel is installed inside the support base, a solar panel and an infrared sensor are fixedly connected to the upper end of the support base, an electric valve is fixedly installed at the output end of the helium cylinder, and the gas delivery pipe and the traction rope both pass through the middle of the support column and extend to the top of the support column.

[0007] Preferably, a gimbal camera is rotatably mounted at the bottom of the fixed rod, connecting ropes are fixedly connected to both ends of the fixed rod, an arc-shaped spring is fixedly connected inside the fixed rod, and one end of each pair of connecting ropes is fixedly connected to a compressed balloon.

[0008] Preferably, the fixing rod comprises three parts: an upper support plate, a lower support plate, and a central shaft. A baffle extending upward and downward is provided at the hinge point between the lower support plate and the central shaft. The upper end of the baffle abuts against the upper support plate, and the lower end of the baffle is fixedly connected to one end of an arc-shaped spring. One end of the arc-shaped spring is fixedly connected to the central shaft.

[0009] Preferably, the shooting assembly further includes a vertical limiting plate fixedly connected to the support column. The vertical limiting plate is distributed on both sides of the fixed rod. A flip baffle that is rotatably connected to the support column is provided on the upper side of both ends of the fixed rod. One end of the flip baffle abuts against an elastic limiting strip fixedly connected to the support column. The flip baffle abuts against the fixed rod.

[0010] Preferably, the compressed balloons are symmetrically distributed on the upper end of the support column, a diverter is fixedly connected to the top of the air supply pipe, a connecting hose is fixedly connected to the diverter, and a fixing nozzle is fixedly connected to the side of the compressed balloon.

[0011] Preferably, the fixing nozzle has elastic protrusions arranged in a ring inside, and the output end of the connecting hose is inserted into the fixing nozzle.

[0012] Preferably, the blocking assembly includes a top protective plate located at the top of the support column and rotatably connected to the support column, and a spring push plate disposed inside the support column. The top protective plate is fixedly connected to a fixed hook at the end away from the hinge point with the support column, and a pair of limiting protrusions are provided on the side of the top protective plate near the hinge point with the support column. The bottom of the spring push plate is fixedly connected to the support column, and the top of the spring push plate abuts against the limiting protrusions.

[0013] Preferably, the blocking assembly further includes a spring hook and a movable plate disposed inside the support column. The spring hook is located between a pair of compressed balloons and is slidably connected to the support column. The spring hook is hooked to a fixed hook.

[0014] Preferably, the movable plate abuts against a compressed balloon, the movable plate is slidably connected inside the support column, and a sloping insert is fixedly connected to the side of the movable plate facing the spring hook, the sloping insert abutting against the lower side of the spring hook.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention utilizes a combination of a compressed balloon and a gimbal camera to facilitate aerial photography of fire information for rapid response. The compressed balloon, connected by a rope, pulls a fixed rod upwards. As it ascends, an arc-shaped spring inside the fixed rod pushes it to unfold into a cross shape, maintaining the stability of the gimbal camera at the bottom. This continues until the gimbal camera is located 10-15 meters above the treetop, allowing for detailed photography of the fire, confirmation of various fire-related information, and rapid, targeted action to minimize losses. This invention, through the combination of a fixed rod and a flip-up baffle, facilitates the limiting of the compressed balloon, allowing it to be filled with enough gas to lift the gimbal camera to a suitable distance. The compressed balloon pulls the fixed rod upward via a connecting rope. At this time, the flip-up baffle and the elastic limiting strip will block the fixed rod. Simultaneously, gas is continuously added to the compressed balloon, increasing the pulling force on the fixed rod until the flip-up baffle is pulled over the elastic limiting strip. This ensures that the compressed balloon has sufficient pulling force to lift the fixed rod and the gimbal camera to a sufficient height, ensuring a sufficient shooting range and comprehensive acquisition of fire information. This invention, through the combination of a blocking component and a compression balloon, facilitates the opening of the fixed hook during use. In the absence of fire, the top protective plate seals the top of the support column, preventing damage to the internal components. When the compression balloon inflates, it squeezes the movable plate towards the spring hook. At this point, the inclined insert pushes the spring hook, causing it to disengage from the fixed hook. The spring pusher then pushes the top protective plate to flip, opening the top of the support column. This ensures the compression balloon has sufficient space to inflate and rise rapidly.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1 to 10 As shown, the present invention provides a smart forestry smoke and fire alarm device, including a support base 1 and a support column 2, with a first camera 3 installed on the upper end of the support column 2, and also includes: The shooting component 4 is installed inside the support base 1 and the support column 2 and is used to shoot the fire from a high place. The balloon assembly 5, which is installed inside the support base 1 and the support column 2, is used to carry the shooting assembly 4 to a high place; The blocking component 6 is located on top of the support column 2 and is used to block and protect the shooting component 4 and the balloon component 5. Among them, the shooting component 4 includes a winch 41 installed inside the support base 1, a traction rope 42 wound in the middle of the winch 41, and a fixed rod 44 fixedly connected to the top of the traction rope 42. The balloon assembly 5 includes a helium cylinder 51 fixedly connected inside the support base 1 and a pair of compressed balloons 52 placed inside the upper end of the support column 2. The output end of the helium cylinder 51 is fixedly connected to a gas delivery pipe 53.

[0020] like Figure 1 , Figure 2and Figure 3 As shown, a control panel is installed inside the support base 1. A solar panel 7 and an infrared sensor 8 are fixedly connected to the upper end of the support base 1. An electric valve is fixedly installed at the output end of the helium cylinder 51. The gas supply pipe 53 and the traction rope 42 both pass through the middle of the support column 2 and extend to the top of the support column 2.

[0021] The above scheme employs the following: By setting up a first camera 3 and an infrared sensor 8, daily fire monitoring can be carried out, and the solar panel 7 generates electricity to ensure energy storage. The electric valve installed on the helium cylinder 51 can control the output of the helium cylinder 51 to inflate the compressed balloon 52 as soon as the first camera 3 and infrared sensor 8 detect a fire, so as to determine the location, range, and direction of the fire immediately for targeted handling. The length of the traction rope 42 is set according to the specific tree species, so that the gimbal camera 43 can be 10m to 15m above the treetop to ensure a shooting range of 3km to 5km, thereby ensuring complete control of fire information.

[0022] like Figures 3 to 5 As shown, a gimbal camera 43 is rotatably mounted on the bottom of the fixed rod 44. Connecting ropes 45 are fixedly connected to both ends of the fixed rod 44. An arc spring 46 is fixedly connected inside the fixed rod 44. One end of a pair of connecting ropes 45 is fixedly connected to a compressed balloon 52. The fixed rod 44 includes three parts: an upper support plate, a lower support plate, and a central shaft. A baffle extending upward and downward is provided at the hinge point between the lower support plate and the central shaft. The upper end of the baffle abuts against the upper support plate, and the lower end of the baffle is fixedly connected to one end of the arc spring 46. One end of the arc spring 46 is fixedly connected to the central shaft.

[0023] The above solution involves setting a fixed rod 44 to support the gimbal camera 43. The fixed rod 44 unfolds into a cross shape and is fixedly connected to the compressed balloon 52 at the four corners by connecting ropes 45. This provides a relatively stable shooting environment for the gimbal camera 43. The gimbal camera 43 itself can then be adjusted to improve the shooting clarity. The curved spring 46 ensures that the fixed rod 44 can stably unfold into a cross shape after being moved out of the support column 2, preventing the connecting ropes 45 from getting tangled and causing unstable shooting.

[0024] like Figure 6 and Figure 8 As shown, the shooting assembly 4 also includes a vertical limiting plate 47 fixedly connected to the support column 2. The vertical limiting plate 47 is distributed on both sides of the fixed rod 44. Both ends of the fixed rod 44 are provided with a flip baffle 48 rotatably connected to the support column 2. One end of the flip baffle 48 abuts against an elastic limiting strip 49 fixedly connected to the support column 2. The flip baffle 48 abuts against the fixed rod 44.

[0025] The above solution involves setting a vertical limiting plate 47 and a flipping baffle 48. The vertical limiting plate 47 limits the fixed rod 44, keeping it vertical and preventing it from flipping and shaking when the compressed balloon 52 is pulled out of the support column 2. This ensures stability. The cooperation of the flipping baffle 48 and the elastic limiting strip 49 allows the compressed balloon 52 to be filled with enough gas before moving the fixed rod 44 upward, preventing insufficient upward movement that would prevent the capture of the full view and the loss of fire information.

[0026] like Figures 3 to 8 As shown, the compressed balloons 52 are symmetrically distributed on the upper end of the support column 2. The top of the air supply pipe 53 is fixedly connected to the diverter 54, and the diverter 54 is fixedly connected to the connecting hose 55. The side of the compressed balloon 52 is fixedly connected to the fixing nozzle 56. The fixing nozzle 56 has elastic protrusions arranged in a ring inside, and the output end of the connecting hose 55 is inserted into the fixing nozzle 56.

[0027] The above solution is adopted as follows: By setting up the balloon assembly 5, the compressed balloon 52, after being inflated, drives the fixing rod 44 and the gimbal camera 43 to rise to a sufficient height. The setting of the air supply pipe 53 and the diverter 54 ensures that the pair of compressed balloons 52 can maintain a synchronous inflation state, avoiding uneven inflation on both sides and causing imbalance. The elastic protrusion set inside the fixing nozzle 56 ensures that the connecting hose 55 will not come out after insertion, and will only come out when subjected to sufficient tension, thereby ensuring the stability of inflation of the compressed balloon 52.

[0028] like Figure 6 , Figure 8 and Figure 9 As shown, the blocking assembly 6 includes a top protective plate 61 located at the top of the support column 2 and rotatably connected to the support column 2, and a spring push plate 64 disposed inside the support column 2. A fixed hook 62 is fixedly connected to one end of the top protective plate 61 away from the hinge point with the support column 2. A pair of limiting protrusions 63 are provided on the side of the top protective plate 61 near the hinge point with the support column 2. The bottom of the spring push plate 64 is fixedly connected to the support column 2, and the top of the spring push plate 64 abuts against the limiting protrusions 63.

[0029] The above solution is adopted: the top protective plate 61 can block the gimbal camera 43 and the compressed balloon 52 when there is no fire, so as to prevent them from being damaged. The limiting protrusion 63 and the spring push plate 64 can directly push and flip the top protective plate 61 when it is necessary to open, so as to ensure that the compressed balloon 52 and the gimbal camera 43 rise stably.

[0030] like Figures 8 to 10As shown, the blocking assembly 6 also includes a spring hook 65 and a movable plate 66 disposed inside the support column 2. The spring hook 65 is located between a pair of compressed balloons 52 and is slidably connected to the support column 2. The spring hook 65 is hooked to the fixed hook 62. The movable plate 66 abuts against one of the compressed balloons 52. The movable plate 66 is slidably connected inside the support column 2, and a sloping insert 67 is fixedly connected to the side of the movable plate 66 facing the spring hook 65. The sloping insert 67 abuts against the lower side of the spring hook 65.

[0031] The above solution is adopted: the spring hook 65 and the fixed hook 62 hooks prevent the top protective plate 61 from opening from the outside, avoiding damage by wild animals. At the same time, the movable plate 66 and the inclined insert 67 on the side of the spring hook 65 can ensure that the spring hook 65 can be quickly released from the hooks of the fixed hook 62 after a fire is discovered, so that the compressed balloon 52 can be continuously inflated and expanded, which can facilitate the gimbal camera 43 to rise and take pictures of the fire.

[0032] Working principle and usage process of this invention: When the first camera 3 and the infrared sensor 8 jointly detect a fire, the control panel inside the support base 1 transmits the signals received from the first camera 3 and the infrared sensor 8. At the same time, the control panel activates the electric valve at the output end of the helium cylinder 51, causing the helium cylinder 51 to inflate the compressed balloon 52 through the gas supply pipe 53. Simultaneously, the gimbal camera 43 is activated. When the compressed balloon 52 inflates, it will press the movable plate 66 towards the spring hook 65. At this time, the inclined insert 67 on the inner side of the movable plate 66 presses the spring hook 65 to move, causing the spring hook 65 to move and disengage from the fixed hook 62. At this time, the spring push plate 64 will push the limiting protrusion 63 to move upward, thereby pushing the top protective plate 61 to flip, opening the top of the support column 2 so that the compressed balloon 52 can continue to inflate. As the compressed balloon 52 inflates, it generates an upward pull. At this time, the compressed balloon 52 pulls the fixed rod 44 upward through the connecting rope 45. Simultaneously, the flipping baffle 48 and the elastic limiting strip 49 block the fixed rod 44 until the pull of the compressed balloon 52 on the fixed rod 44 is enough to pull the flipping baffle 48 over the elastic limiting strip 49. Then, the compressed balloon 52 will drive the fixed rod 44 to rise. As it rises, the arc spring 46 inside the fixed rod 44 will push the fixed rod 44 to unfold into a cross shape to maintain the stability of the bottom gimbal camera 43. During the process of the compressed balloon 52 pulling the fixed rod 44 and the gimbal camera 43 upward, the traction rope 42 is continuously pulled and released until the gimbal camera 43 is 10m to 15m away from the treetop. This allows the range and direction of the fire to be captured. Ground personnel can directly determine the location of the fire based on the position of the balloon in the air.
