DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example 1

[0035] See also Figures 1-5, A forest fire prevention monitoring and emergency alarm device, including a monitoring and alarm component 1 and a mobile vehicle 2 for carrying the monitoring and alarm component 1. The monitoring and alarm component 1 is provided with structures such as a pan-tilt, a smoke monitor, a wireless communication component, and a GPS locator for fire monitoring. Among them, the pan-tilt is installed with a camera having a temperature monitoring function, and when a fire is detected, the fire situation will be transmitted to the client in a timely manner and an alarm will be issued. The role of the mobile vehicle 2 is to carry the monitoring and alarm component 1 to move in the forest with complex terrain, thereby expanding the monitoring range. The complex terrain refers to more surface obstacles and spatial obstacles. For example, the components of the surface obstacles are mainly composed of soft and muddy surface soil, many vine plants, and branches and leaves laid on the surface. The spatial obstacles are mainly composed of hanging vine plants and drooping branches, etc. In this technical solution, the mobile vehicle 2 is provided with the function of moving and developing in the forest with the above complex terrain.

[0036] Specifically, the mobile vehicle 2 includes a chassis 21 and two rollers 22 respectively located on both sides of the chassis 21. Preferably, in specific implementation, the chassis 21 is a cylindrical structure and a coaxial drive shaft 214 is sleeved through it. The drive shaft 214 is rotatably connected to the chassis 21, and the inner spherical walls of the two rollers 22 are respectively fixedly connected to both ends of the drive shaft 214. Thus, when the drive shaft 214 rotates, it can drive the two rollers 22 to rotate simultaneously. A steering tailstock 23 is fixedly connected to the outer peripheral wall of the chassis 21. When the two rollers 22 roll forward, they can drive the chassis 21 to move forward. The steering tailstock 23 plays a role in controlling the steering movement of the mobile vehicle 2. Among them, the volume of the roller 22 is larger than that of the chassis 21, so that the contact area between the roller 22 and the ground can be increased, enabling the roller 22 to effectively roll over the obstacles on the ground when rotating, greatly improving the moving stability and moving speed. At the same time, the setting of the steering tailstock 23 enables the device to shuttle flexibly among the spatial obstacles. Among them, the two rollers 22 are of a shell structure and their opposite surfaces are spherical. The spherical setting greatly reduces the probability of winding sundries when the roller 22 moves and turns. When in use, the inner spherical walls of the two rollers 22 are respectively fixedly connected to both ends of the drive shaft 214. A sealing sleeve 223 is fixedly connected to one side of the roller 22. The sealing sleeve 223 is sleeved outside the chassis 21 and they are in sealed cooperation. The inner wall of the sealing sleeve 223 is bonded with sealing felt, aiming to eliminate the gap between the sealing sleeve 223 and the chassis 21 and prevent sundries from entering the rotating gap between the roller 22 and the chassis 21. The monitoring and alarm component 1 is arranged above the steering tailstock 23 and is connected to the chassis 21.

[0037] Among them, the opposite sides of the two rollers 22 are slidably connected with the circumferentially uniformly distributed escape gear rods 221. In the specific implementation, it is preferred that one side of the roller 22 is fixedly connected with a guide sleeve 222 that surrounds the sleeve 223 and is sleeved on the outside of the escape gear rod 221. The escape gear rod 221 has the function of entering and exiting the roller 22. When the escape gear rod 221 located on the two rollers 22 is in the state of surrounding the chassis 21 when it is in the machine limit extension, the roller 22 will drive the escape gear rod 221 to move in a circle when rolling. The role of the escape gear rod 221 is to increase the effective driving force of the roller 22. For example, when in use, when the bottom of the chassis 21 is supported by an obstacle with a larger hardness, the pressure between the roller 22 and the ground is greatly reduced, and it cannot drive the device to walk when it rotates, thereby controlling the lower escape gear rod 221 to extend, and the escape gear rod 221 will move the above-mentioned obstacle with a larger hardness to push the device forward to escape.

[0038] Furthermore, an escape limit portion 24 connected to the chassis 21 is provided in the roller 22, and the escape limit portion 24 makes the connecting line of the free ends of all the escape gear rods 221 on adjacent rollers 22 be on the same elliptical line, that is, when a part of adjacent escape gear rods 221 on the roller 22 is in a state of being immersed in the roller 22, the remaining part of the escape gear rods 221 is in a state of extending out of the roller 22. This arrangement has the function of preventing obstacles such as vines, weeds and branches from being entangled on the escape gear rods 221.

[0039] Specifically, the escape limiter 24 includes a positioning wheel 241, a support spring 242, a shaping ring plate 243 and a control assembly 244. The positioning wheel 241 is rotatably connected to one side of the chassis 21 and is coaxially arranged with the drive shaft 214. The shaping ring plate 243 is sleeved on the outside of the positioning wheel 241 and the two are inclined to each other. The center of the positioning wheel 241 and the center of the shaping ring plate 243 coincide with each other. When in use, the positioning wheel 241 and the chassis 2 1, the outer sleeve of the escape gear rod 221 is provided with a support spring 242 and one end is provided with a pad body 2211 that rolls with one side of the shaping ring plate 243. In specific implementation, a ball that presses against the surface of the shaping ring plate 243 can be provided on the pad body. Under the elastic thrust of the support spring 242, the pad body 2211 presses against the shaping ring plate 243, and the shaping ring plate 243 in an inclined state makes a circle of the escape gear rod 221 in a state of different extended lengths. When the positioning wheel 241 rotates relative to the chassis 21, the shaping ring plate 243 rotates around the driving shaft 214, and then uses its inclined surface to push each escape gear rod 221 to slide axially, and the corresponding support spring 242 will perform telescopic movement. This arrangement has the advantage of eliminating the negative effects of the escape gear rod 221. For example, when the escape gear rod 221 at the bottom is in an extended state and is inserted into a hard wood, which makes it difficult for the roller 22 to roll, the escape gear rod 221 is controlled to escape from the obstacle by controlling the rotation of the positioning wheel 241. The control assembly 244 is used to control the positioning wheel 241 to rotate relative to the chassis 21.

[0040] When the above-mentioned control combination 244 is implemented, it is preferred that a bearing sleeve 211 sleeved on the outside of the driving shaft 214 is welded on both sides of the chassis 21, and a groove-type frame 212 fixedly connected to the top bearing sleeve 211 is provided in the chassis 21. One roller 22 corresponds to a group of control combinations 244, and the control combination 244 includes a control motor 2441, a driving gear 2442 and a passive gear 2443. The positioning wheel 241 is sleeved on the outside of the bearing sleeve 211 and the two rotate in coordination. One side of the positioning wheel 241 is fixedly connected to the passive gear 2443. The control motor 2441 is fixedly set on the groove-type frame 212 and its output shaft is fixedly connected to the driving gear 2442 meshing with the passive gear 2443. Starting the control motor 2441 can control the rotation of the positioning wheel 241.

[0041] Among them, a driving motor 25 is fixedly connected inside the groove-shaped frame 212, and the output shaft of the driving motor 25 is fixedly connected to the input bevel gear 251. The external fixed sleeve of the driving shaft 214 is provided with a passive bevel gear 2141 meshing with the input bevel gear 251. The driving motor 25 drives the driving shaft 214 to rotate through the meshing cooperation between the input bevel gear 251 and the passive bevel gear 2141.

[0042] In the present technical solution, the steering tailstock 23 includes a tail cylinder 231, a grooved wheel frame 232 and a steering motor 233. One end of the tail cylinder 231 is fixedly connected to the outer peripheral wall of the chassis 21, and the other end is rotatably connected to a transmission shaft 2311. The transmission shaft 2311 and the tail cylinder 231 are coaxially arranged. A connecting shaft 23211 is fixedly connected to the middle part of one side of the cross beam 2321 on the grooved wheel frame 232. One end of the connecting shaft 23211 is fixedly connected to an intermediate shaft 232111 rotatably connected to the transmission shaft 2311. The intermediate shaft 232111 is perpendicular to the connecting shaft 23211, and the intermediate shaft 232 111 and the rotation axis of the transmission shaft 2311 are perpendicular to the transmission shaft 2311. When in use, the grooved wheel frame 232 contacts the ground and the two rollers 22 enable the device to stably contact the ground. When steering is required, the grooved wheel frame 232 is controlled to swing left and right relative to the tail cylinder 231. A roller 2322 is arranged in the grooved wheel frame 232. In specific implementation, it is preferred that a support shaft 2323 is fixedly connected in the grooved wheel frame 232. The roller 2322 is sleeved on the support shaft 2323 and is composed of a plurality of independent rollers. The passive rotation of the twelve rollers 2322 is smoother. When the grooved wheel frame 232 swings left and right, the axis of the roller 2322 and the rotation axis of the roller 22 are in a non-parallel state, so that under the guidance of the roller 2322, the device turns as a whole. A bevel gear 1 2321111 is fixedly connected to the bottom of the intermediate shaft 232111, and a bevel gear 2 2312 meshing with the bevel gear 1 2321111 is fixedly sleeved on the tail cylinder 231, so that when the control transmission shaft 2311 is rotated left and right relative to the tail cylinder 231, the grooved wheel frame 232 will be driven to rotate left and right and swing left and right accordingly. This arrangement makes it possible for one of the rollers 22 to be in a state of being separated or nearly separated from the ground when the device is turning, and the outer spherical surface of the other roller 22 (the roller 22 corresponding to the turning direction) will contact the ground, and this arrangement can improve the reliability and stability of the device turning. The steering motor 233 is fixedly arranged in the tail cylinder 231 and its output shaft is fixedly connected to the other end of the transmission shaft 2311, and the steering motor 233 provides driving force for the rotation of the transmission shaft 2311.

[0043] In this embodiment, a cantilever 213 located above the tail cylinder 231 is welded to the outer peripheral wall of the chassis 21. When the device is placed on the ground, the cantilever 213 is approximately in a horizontal state, and one end thereof is in a tangential connection state with the top of the chassis 21. This arrangement can avoid the problem of hanging between the cantilever 213 and space obstacles. A base plate 11 is provided on the monitoring alarm component 1. The base plate 11 plays a role in supporting the above-mentioned pan-tilt head, smoke detector, wireless communication component, GPS locator and camera. A support arm 111 connected to the free end of the cantilever 213 for vertical rotation is welded to the bottom of the base plate 11. An adjusting motor 2131 for controlling the rotation of the support arm 111 is fixedly connected to one side of the cantilever 213. In specific implementation, the output shaft of the adjusting motor 2131 is fixedly connected to the support arm 111. When the adjusting motor 2131 is started to control the rotation of the support arm 111, it can drive the base plate 11 to flip. At this time, the monitoring equipment installed on the base plate 11 will be transferred to the bottom to avoid collision and damage to the monitoring equipment by obstacles in the forest.

[0044] Working principle: Before use, an imaging camera is installed on the chassis 21, and a remote control component is installed inside the chassis 21, so that an operator can remotely operate the movement of the device. When in use, the device is placed in a forest. Due to its large outer diameter, the roller 22 will not be submerged by surface obstacles. When the bottom of the chassis 21 is pressed by the obstacles on the ground, the pressure between the roller 22 and the ground is greatly reduced. The roller 22 cannot push the device forward when it rotates. At this time, the control motor 2441 is started, and the positioning wheel 241 rotates under the meshing cooperation of the active gear 2442 and the passive gear 2443, so that the shaping ring plate 243 is in a state of tilting at the bottom toward the chassis 21. At this time, the partial escape gear rod 221 at the lower part of the roller 22 is in a state of extending and pressing against the above-mentioned obstacle. Then the roller 22 is controlled to rotate, and the escape gear rod 221 will push the obstacle backward, thereby driving the traction of the device to realize the escape movement function. Therefore, the rolling movement mode of the roller 22 is combined with the axial movement structure of the escape gear rod 221, so that the device has the function of pioneering and moving in the forest.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
