Description

Technical Field

[0001] The present invention relates to the technical field of forest fire prevention equipment, and more specifically to a forest fire monitoring device based on a hot air balloon. Background Art

[0002] Forest fire is the most dangerous enemy of the forest and the most terrible disaster in the forestry industry. It will bring the most harmful and devastating consequences to the forest. Forest fire not only burns large tracts of forest and harms animals in the forest, but also reduces the reproductive capacity of the forest, causes soil impoverishment and destroys forest water conservation, and even causes the ecological environment to lose balance. When the forest is on fire, due to the dense forest, it is impossible to observe whether the forest is on fire in time on the ground. By the time it is discovered, the fire is often out of control, causing huge losses.

[0003] In order to facilitate the monitoring of forest fires, the forest can be monitored from the air. If a cruise drone is used to monitor the forest from the air, the cruise drone moves at a fast speed, the shooting screen of the forest switches quickly, and the monitoring is inaccurate. If a hovering drone is used, the monitoring range is smaller, and both require a lot of energy and have limitations. It is necessary to use a hot air balloon to monitor forest fires.

[0004] In the prior art, hot air balloons mainly heat the air inside the balloon bag to make the balloon float. By installing a camera under the balloon, the forest can be monitored. However, in actual use, hot air balloons mainly heat the air by burning fuel, and need to carry a large amount of fuel, which increases their own weight. In addition, the movement of hot air balloons mainly depends on wind power, and the monitoring range cannot be controlled. Summary of the invention

A second fixed shaft 19 is installed on the other side of the first gear 5. A fourth rolling bearing 20 is installed at the upper end of the second fixed shaft 19. A fifth gear 21 is installed outside the fourth rolling bearing 20. The fifth gear 21 meshes with the first gear 5. A fifth rolling bearing 22 is installed below the fourth rolling bearing 20. A sixth gear 23 is installed outside the fifth rolling bearing 22. Two support frames 24 are installed on one side surface of the hanging basket 2. A sixth rolling bearing 25 is installed on one side of the support frame 24. A transmission shaft 26 is provided on one side of the hanging basket 2. Both ends of the transmission shaft 26 pass through the sixth rolling bearing 25 and extend to the outside of the support frame 24. A seventh gear 27 is installed at the upper end of the transmission shaft 26. The seventh gear 27 is connected to the sixth gear 23 through a transmission chain 63. A third bevel gear 28 is installed at the lower end of the transmission shaft 26. A placement platform 29 is installed on one side of the hanging basket 2. A steering propeller 30 is installed on the placement platform 29. The power input end of the steering propeller 30 is installed with a fourth bevel gear 31. The fourth bevel gear 31 meshes with the third bevel gear 28. Intercepting platforms 32 are installed at both ends of the upper surfaces of the first bevel gear 10 and the sixth gear 23. Transmission columns 33 are installed on both sides of the lower surfaces of the second gear 8 and the fifth gear 21.

[0032] The limiting mechanism includes universal wheels 34 fixedly installed at the four corners of the lower surface of the hanging basket 2. On both sides inside the hanging basket 2, there are movable platforms 35. At the four corners of the lower surface of the movable platform 35, guide wheels 36 are installed. Below the guide wheels 36, there is a guide slideway 37, which is installed on the lower surface inside the hanging basket 2. At the lower end of one side surface of the movable platform 35, a plurality of limiting rods 38 are installed. At the upper ends of the limiting rods 38, a plurality of first universal ball bearings 39 are installed. On both sides of the hanging basket 2, a plurality of limiting holes 40 are opened. One end of the limiting rod 38 extends from the limiting hole 40 to the outside of the hanging basket 2. On one side of the lower surfaces of the first bevel gear 10 and the sixth gear 23, there is a fixed rod 41. On one side of the lower end of the fixed rod 41, a pushing wheel 42 is installed. On the movable platform 35, there are two through holes 43. Inside the through holes 43, there is a lifting platform 44. On both sides of the upper end of the lifting platform 44, there are intercepting plates 45. At the lower end of the hanging basket 2, there are four through holes 46. The lower end of the lifting platform 44 extends from the through hole 46 to the lower part of the hanging basket 2. On the lower surface of the lifting platform 44, a plurality of second universal ball bearings 47 are installed. The upper end of the lifting platform 44 is located on one side of the pushing wheel 42. By the forward and reverse rotation of the rotating motor 4, it is convenient for the hot air balloon to move and change its moving direction. By the reverse rotation of the rotating motor 4, the limiting rod 38 can be retracted, facilitating the lifting of this device.

[0033] The transmission column 33 includes transmission rods 48 respectively fixedly installed on both sides of the lower surfaces of the second gear 8 and the fifth gear 21. At the lower end of the transmission rod 48, there is a notch 49. At the lower end of the transmission rod 48, there is a connecting rod 50. The upper end of the connecting rod 50 is located on one side of the notch 49. The upper end of the connecting rod 50 is connected to the lower end of the transmission rod 48 through a hinge. The intercepting platform 32 is located on one side below the connecting rod 50. The opening directions of the notches 49 on the transmission rods 48 on both sides of the lower surfaces of the second gear 8 and the fifth gear 21 are opposite. Through the notch at the lower end of the transmission rod 48, the connecting rod 50 can be deflected, so that the second gear 8 and the fifth gear 21 respectively drive the first bevel gear 10 and the sixth gear 23 to rotate only in one direction.

[0034] The placing mechanism includes a placing table 51 fixedly installed on the ground. On both sides of the upper surface of the placing table 51, there are limiting platforms 52. Inside the limiting platforms 52, there are limiting grooves 53. Placing the limiting rod 38 in the limiting groove 53 can prevent the hot air balloon from deflecting to one side when it is not fully heated.

[0035] The positioning and monitoring mechanism includes a transparent protective box 54 fixedly installed on the lower surface of the hanging basket 2. Inside the transparent protective box 54, there is a wireless camera 55. On one side of the upper end of the fixed platform 3, there is an electronic compass 56. On one side of the electronic compass 56, there is a GPS locator 57. On one side of the hanging basket 2, there is an ultrasonic bird repeller 58. By the electronic compass 56 and the GPS locator 57, the moving range of this device can be guaranteed. By using the wireless camera 55 to shoot the pictures of the forest for monitoring, and by using the ultrasonic bird repeller 58 to drive away birds to prevent the damage of this device.

[0036] The fixing mechanism includes an L-shaped fixing hole 59 located on one side of the lower end of the lifting platform 44. An L-shaped connecting shaft 60 is installed on one side inside the through hole 46, which can limit the lifting platform 44 to prevent it from moving randomly.

[0037] The first gear 5, the first bevel gear 10, the third gear 15, the sixth gear 23, and the third bevel gear 28 are large gears, and the second gear 8, the second bevel gear 14, the fourth gear 18, the fifth gear 21, the seventh gear 27, and the fourth bevel gear 31 are small gears. By driving the small gears with the large gears, the rotation speed of the propeller can be increased and the power can be increased when the rotating motor 4 rotates.

[0038] The rotation of the propulsion propeller 17 can push the solar hot air balloon 1 to move radially, and the rotation of the steering propeller 30 can push the solar hot air balloon 1 to rotate around the central axis.

[0039] Pushing platforms 61 are installed at the upper ends of two lifting platforms 44 on one side of the first bevel gear 10, and L-shaped reset platforms 62 are installed at the upper ends of two lifting platforms 44 on one side of the sixth gear 23. The moving platform 35 moves due to the action of the driving wheels 42 on the pushing platforms 61 and the L-shaped reset platforms 62.

[0040] In this implementation scheme, the electrical equipment of this device is controlled by an external controller. Technical means such as the lifting of the solar hot air balloon 1 in this device, the rotation of the rotating motor 4, transmitting the image of the wireless camera 55 to the display screen, the pointing function of the electronic compass 56, and the positioning function of the GPS locator 57 are all existing mature technologies and will not be elaborated here.

[0041] When the device is on the ground, the universal wheels 34 under the hanging basket 2 rest on the placing table 51. One end of the limit rod 38 passes through the limit hole 40 and extends into the limit groove 53 on the limit platform 52. When the solar hot air balloon 1 ascends, the wireless camera 55, electronic compass 56, GPS locator 57, and ultrasonic bird repeller 58 are activated, and the electric energy is provided by the storage battery in the solar hot air balloon 1. The heater in the solar hot air balloon 1 heats the balloon at the upper end of the solar hot air balloon 1, generating an upward lifting force on the solar hot air balloon 1, but not enough to make the solar hot air balloon 1 ascend. One end of the limit rod 38 extends into the limit groove 53, and both ends of the hanging basket 2 are located inside the limit platform 52, which can prevent the solar hot air balloon 1 from deflecting to one side when it is not fully ascending, reducing potential safety hazards. When the hot air in the solar hot air balloon 1 is sufficient to make the solar hot air balloon 1 ascend, the rotating motor 4 is started to reverse and drives the first gear 5 to rotate. Both ends of the first gear 5 are respectively engaged with the second gear 8 and the fifth gear 21, driving the second gear 8 and the fifth gear 21 to rotate. The fifth gear 21 is installed on the second fixed shaft 19 through the fourth rolling bearing 20, and can drive the fifth gear 21 to rotate outside the fourth rolling bearing 20. The sixth gear 23 is installed on the second fixed shaft 19 through the fifth rolling bearing 22, making the sixth gear 23 and the fifth gear 21 concentrically corresponding. When the rotating motor 4 reverses to drive the sixth gear 23 to rotate, the acting force on the intercepting platform 32 through the transmission column 33 can drive the sixth gear 23 to rotate. The connecting rod 50 on the transmission column 33 is connected by a hinge and can rotate below the transmission rod 48. When the connecting rod 50 rotates outward to the outside of the notch 49, the upper end of the connecting rod 50 is not blocked and can rotate. When the connecting rod 50 rotates inward to the inside of the notch 49, the upper end of the connecting rod 50 is blocked by the transmission rod 48 and cannot rotate. When the rotating motor 4 reverses to drive the sixth gear 23 to rotate, the upper end of the connecting rod 50 rotates inward to the inside of the notch 49, thus being blocked by the transmission rod 48 and unable to rotate, and driving the sixth gear 23 to rotate. When the sixth gear 23 rotates, it can drive the pushing wheel 42 to rotate through the fixed rod 41. As shown by Figure 9 When the right pushing wheel 42 rotates clockwise around the second fixed shaft 19, it can push the L-shaped reset platform 62 inward, and through the lifting platform 44, push the moving platform 35 inward. By moving the guide wheel 36 in the guide slideway 37, the friction can be reduced, thus pulling the limit rod 38 out of the limit groove 53. The first universal ball 39 can reduce the friction when the limit rod 38 moves in the limit groove 53. After the limit rod 38 is taken out of the limit groove 53, the solar hot air balloon 1 is not subject to resistance and can overcome gravity and rise upward.

[0042] When the mobile platform 35 and the lifting platform 44 move inward, the L-shaped fixing hole 59 on one side of the lower end of the lifting platform 44 moves above the L-shaped connecting shaft 60. After the hot air balloon rises, under the action of gravity, the lower end of the lifting platform 44 moves downward through the through hole 43 and the through hole 46, and the upper end of the lifting platform 44 lands above the mobile platform 35 through the blocking plate 46 to prevent further falling, so that the upper end of the L-shaped connecting shaft 60 is located within the L-shaped fixing hole 59 to fix the lifting platform 44 and prevent it from shaking. At this time, the pushing platform 61 and the L-shaped reset platform 62 at the upper end of the lifting platform 44 are located below the driving wheel 42, and when the driving wheel 42 rotates, no force will be exerted on the lifting platform 44.

[0043] When the solar hot air balloon 1 rises to a certain height, its position is located through the GPS locator 57, and the direction is pointed through the electronic compass 56. The rotation speed of the rotating motor 4 is increased, and when the rotating motor 4 rotates in reverse to drive the sixth gear 23 to rotate, through the transmission of the transmission chain 63, the seventh gear 27 rotates on the transmission shaft 26, and drives the transmission shaft 26 to rotate between the two sixth rolling bearings 25, so that the third bevel gear 28 rotates. The third bevel gear 23 meshes with the fourth bevel gear 31, thereby driving the steering propeller 30 to rotate. The steering propeller 30 can push the hanging basket 2 to rotate around the central axis of the solar hot air balloon 1 from the side, so that the device changes direction. The orientation of the device is judged by the electronic compass 56. When the specified direction is reached, the reverse rotation of the rotating motor 4 is stopped. The solar hot air balloon 1 converts solar energy into electric energy, which can extend the continuity of the device monitoring.

[0044] When the rotating motor 4 rotates in reverse, it drives the second gear 8 to rotate outside the first rolling bearing 7. The second rolling bearing 9 is located below the first rolling bearing 7. When the second gear 8 rotates, the first bevel gear 10 can be driven through the transmission column 33 and the blocking platform 32. The connecting rod 50 on the transmission column 33 is connected by a hinge and can rotate below the transmission rod 48. When the connecting rod 50 rotates outward to the outside of the notch 49, the upper end of the connecting rod 50 is not blocked and can rotate. When the connecting rod 50 rotates inward to the inside of the notch 49, the upper end of the connecting rod 50 is blocked by the transmission rod 48 and cannot rotate. When the rotating motor 4 rotates in reverse to drive the second gear 8 to rotate, the upper end of the connecting rod 50 rotates outward to the outside of the notch 49, and the upper end of the connecting rod 50 is not blocked. When the lower end of the connecting rod 50 touches the blocking platform 32, it tilts to one side, so that the first bevel gear 10 will not be driven to rotate. Therefore, when the rotating motor 4 rotates forward, it can drive the first bevel gear 10 to rotate and will not drive the sixth gear 23 to rotate. When the rotating motor 4 rotates in reverse, it will not drive the first bevel gear 10 to rotate and can drive the sixth gear 23 to rotate.

[0045] When the solar hot air balloon 1 rises to the specified height, by changing the power of the heater, the solar hot air balloon 1 can be suspended in the air. The forest picture is taken by the wireless camera 55 and the picture is transmitted to the monitoring room through wireless signals for monitoring. Through the ultrasonic bird repeller 58, birds can be prevented from interfering with this device. After this device rotates to the specified direction, the rotation motor 4 is started to rotate forward. At this time, it can drive the first bevel gear 10 to rotate. When the first bevel gear 10 rotates, through the meshing of the gears, the second bevel gear 14, the rotating shaft 13, and the third gear 15 can be driven to rotate. Through the meshing of the third gear 15 and the fourth gear 18, the propulsion propeller 17 can be rotated, so as to move this device and expand the monitoring range of this device.

[0046] At the end of the work, this device is moved above the placement table 51 through the forward and reverse rotation of the rotation motor 4. The hanging basket 2 is pushed manually between the two limiting platforms 52. When the hanging basket 2 drops, the second universal ball 47 at the lower end of the lifting platform 44 first contacts the upper surface of the placement table 51, thereby pushing the lifting platform 44 upward. Through the rotation of the second universal ball 47, the friction when this device moves on the placement table 51 can be reduced. When the lifting platform 44 rises, the L-shaped fixing hole 59 moves upward, thereby taking out the L-shaped connecting shaft 60 from the L-shaped fixing hole 59. At this time, the lifting platform 44 rises, and the pushing platform 61 and the L-shaped reset platform 62 rise to one side of the pushing wheel 42. As shown in the appendix Figure 9 When the left pushing wheel 42 rotates counterclockwise around the first fixed shaft 6, the pushing platform 61 is pushed to one side by the pushing wheel 42, so that the lifting platform 44 and the moving platform 35 can move outward, thereby pushing the limiting rod 38 into the limiting groove 53 to limit it.
