[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figures 1 to 5As shown, the utility model provides a portable low-altitude drone image control point spray painting template device, including a base 1, a rotating disk 101 is attached to the top of the base 1, a threaded groove is provided inside the rotating disk 101, a support rod 2 is spirally connected inside the threaded groove of the rotating disk 101, an arc groove is provided on the right side of the support rod 2, a rotating block 202 is slidably connected inside the arc groove of the support rod 2, a latch 201 is penetrated inside the rotating block 202, the latch 201 penetrates the support rod 2, a fixing nut 203 is fixedly connected to the outside of the support rod 2, and the latch 201 penetrates the support rod 2. The pin 201 rotates inside the fixing nut 203, and the extension block 204 is connected to the rotation of the support rod 2 and fits against the inner wall of the arc-shaped groove of the support rod 2. The extension block 204 inside the support rod 2 is pulled out from the arc-shaped groove inside the support rod 2 and forms a perpendicular angle with the base 1. During the rotation process, the extension block 204 is rotationally connected to the pin 201 passing through the arc-shaped groove inside the support rod 2. When the extension block 204 needs to be slid downward along the arc-shaped groove of the support rod 2, it is only necessary to pull out the pin 201 inside the fixing nut 203 outside the support rod 2.

[0028] Specifically, a slot is provided inside the extension block 204, and a threaded rod 3 is rotatably connected inside the slot of the extension block 204. A slider 301 is sleeved on the outside of the threaded rod 3. The bottom end of the slider 301 is fixedly connected to a lifting rod 302, and the lifting rod 302 slides on the bottom end of the threaded rod 3. After the extension block 204 slides upward, the threaded rod 3 inside the extension block 204 rotates clockwise, and the threaded rod 3 drives the outer sleeved slider 301 to slide to the left, thereby driving the lifting rod 302 at the bottom to move.

[0029] Furthermore, a sleeve 303 is sleeved on the outside of the lifting rod 302, and the bottom end of the sleeve 303 is fixedly connected with the spraying device 4. The lifting rod 302 is upgraded inside the sleeve 303, thereby controlling the height of the spraying device 4 and the ground.

[0030] Furthermore, the outer spring 501 of the inkjet device 4 is welded to fix the connecting pipe 401, the outer side of the connecting pipe 401 is sleeved with a sleeve 402, and the bottom end of the sleeve 402 is fixedly connected with an inkjet head 403, and inkjet printing is performed toward the ground through the inkjet head 403, thereby completing the inkjet printing work.

[0031] It is worth mentioning that a shock absorbing cylinder 5 is fixedly connected to the bottom end of the inkjet printing device 4, and a spring 501 is sleeved on the outer side of the shock absorbing cylinder 5. A base plate 502 is tightly arranged at the bottom end of the spring 501. A slide groove is provided inside the base plate 502. A rotating wheel 503 is slidably connected inside the slide groove of the base plate 502, and is tightly pressed against the ground through the rotating wheel 503. When the rotating wheel 503 inside the base plate 502 at the bottom end of the inkjet printing device 4 is close to the ground, it cooperates with the spring 501 and the shock absorbing cylinder 5 at the top end of the base plate 502 for shock absorption, and the sliding of the lifting rod 302 is stopped at this time.

[0032] It is worth mentioning that a cavity is opened inside the base 1, and the inkjet device 4 is arranged inside the cavity of the base 1. The inkjet device 4 inside the base 1 is taken out when in use, and can be put back into the base 1 when not in use.

[0033] Working principle:

[0034] First, the staff places the base 1 at the position where the drone needs to be sprayed, then takes out the spraying device 4 inside the base 1, installs the rotating disk 101 in the circular hole inside the base 1 and fits it, inserts the bottom end of the support rod 2 into the inside of the rotating disk 101, and screws it to tighten it. At this time, the extension block 204 inside the support rod 2 is pulled out from the arc groove inside the support rod 2 and forms a perpendicular angle with the base 1. During the rotation process, the extension block 204 is rotatably connected with the latch 201 passing through the arc groove inside the support rod 2. When it is necessary to slide the extension block 204 downward along the arc groove of the support rod 2, just pull out the support rod 2. The latch 201 inside the fixing nut 203 on the outside of the support rod 2 is sufficient. At this time, the protruding moving blocks at both ends of the left side of the extension block 204 slide in the slide groove inside the support rod 2. At this time, because the protruding moving blocks are stuck in the slide groove inside the support rod 2, the extension block 204 will not detach from the slide groove. When the extension block 204 slides upward, the threaded rod 3 inside the extension block 204 rotates clockwise, and the threaded rod 3 drives the outer sleeved slider 301 to slide to the left, thereby driving the lifting rod 302 at the bottom to move. At this time, the lifting rod 302 drives the inkjet device 4 and the sleeve 303 at the bottom to move to the left.

[0035] When not in use, the device can be completely folded. In a completely folded state, it takes up little space and is easy to carry. When the UAV is flying at a low altitude and the required image control points are small, the printing area is reduced. When the UAV is flying at a high altitude and the required ground image control points are large, the printing area is increased.

[0036] When it is necessary to get close to the ground, the lifting rod 302 slides out from the inside of the sleeve 303, and the spraying device 4 at the bottom of the sleeve 303 is close to the ground. When the rotating wheel 503 inside the base plate 502 at the bottom of the spraying device 4 is close to the ground, and cooperates with the spring 501 and the shock-absorbing cylinder 5 at the top of the base plate 502 for shock absorption, the sliding of the lifting rod 302 is stopped, and the sprayed paint flows through the connecting tube 401 to the inside of the sleeve 402, and is sprayed to the ground through the spray head 403, thereby completing the spraying work, wherein the shaded part is the spraying control area.
