[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are partial embodiments of the present invention, rather than all embodiments.

[0023] In the description of the present invention, it should be understood that the terms "center", "lateral", "longitudinal", "front", "rear", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention. When a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a centered component. When a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centered component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centered component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0024] like Figures 1 to 12 As shown, the present invention is an auxiliary device for unmanned aerial vehicle surveying and mapping, comprising: an unmanned aerial vehicle body 1; a mounting frame 6 installed on the unmanned aerial vehicle body 1; a mounting box 7 fixedly installed on the mounting frame 6; a surveying and mapping camera 2, installed at the bottom of the mounting box 7; a protection mechanism 4 for protecting the surveying and mapping camera 2 when not in use; a cleaning mechanism 3 for cleaning the surveying and mapping camera 2 when in use; a supporting mechanism 5 for supporting the unmanned aerial vehicle body 1; a unmanned aerial vehicle gimbal can also be installed at the bottom of the mounting box 7, and the unmanned aerial vehicle gimbal is used to install the surveying and mapping camera 2 so as to drive the surveying and mapping camera 2 to rotate.

[0025] The supporting mechanism 5 comprises: a supporting frame 51 hingedly mounted on the mounting frame 6 , and a second power source 52 hingedly mounted between the supporting frame 51 and the mounting box 7 .

[0026] There are two groups of support frames 51, which are respectively located on both sides of the drone body 1. When the drone body 1 is not taking off or preparing to take off and land, the two groups of support frames 51 are in a vertical state. When the drone takes off, the two power sources 52 are started, and the output ends of the two power sources 52 are extended, thereby driving the adjacent support frames 51 to rotate at the hinges with the mounting frame 6, so that the two groups of support frames 51 are transformed from a vertical state to a state of being unfolded in a direction away from the drone body 1. When shooting, the height of the surveying and mapping camera 2 can be completely lower than the height of the support frame 51, thereby preventing the support frame 51 from blocking the surveying and mapping camera 2 from framing and shooting.

[0027] It is to be added here that the power source 2 52 is preferably an electric telescopic rod.

[0028] The protective mechanism 4 includes: a protective shell 41 slidably installed on the installation box 7, a connecting rope 42 fixedly installed between the protective shell 41 and the support frame 51, a limiting wheel 43 for limiting the connection rope 42 during movement, and a reset component 44 that is rotatably installed on the fixed plate 10 to drive the protective shell 41 to reset; the reset component 44 includes: a mounting groove 441 opened on the installation box 7, a slide bar 442 slidably installed in the mounting groove 441, the slide bar 442 is fixedly connected to the protective shell 41 and guides the slide bar 442 during movement. The guide rod 443 passes through the side wall of the slide bar 442, and both ends of the guide rod 443 are fixedly installed in the mounting groove 441 to drive the reset spring 444 to reset the protective shell 41, one end of the reset spring 444 is fixedly connected to the slide bar 442, and the other end of the reset spring 444 is fixedly connected to the inner wall of the mounting groove 441.

[0029] There are two groups of protective shells 41, which are located on both sides of the surveying and mapping camera 2. When the surveying and mapping camera 2 is not in use, the two groups of protective shells 41 abut against each other, so that the surveying and mapping camera 2 is located inside the two groups of protective shells 41. At this time, the setting of the protective shells 41 can protect the surveying and mapping camera 2. On the one hand, it can prevent dust from being used when the surveying and mapping camera 2 is not in use, thereby ensuring the normal use of the surveying and mapping camera 2. On the other hand, it can prevent the surveying and mapping camera 2 from being damaged by collision, thereby improving the safety of the surveying and mapping camera 2.

[0030] When the surveying and mapping camera 2 is in use, that is, after the drone body 1 takes off, the two groups of support frames 51 rotate at their hinges with the mounting frame 6, thereby pulling the adjacent connecting ropes 42 to move. Under the limiting action of the limiting wheel 43, the connecting ropes 42 are prevented from being offset. At this time, the connecting ropes 42 drive the adjacent protective shells 41 to move, so that the two groups of protective shells 41 move away from each other, thereby releasing the protection of the surveying and mapping camera 2. When the two groups of protective shells 41 move away from each other, they drive the adjacent sliding bars 442 to move, and the sliding bars 442 drive the adjacent reset springs 444 to deform. Through the setting of the guide rod 443, on the one hand, the moving direction of the protective shell 41 can be guided, and on the other hand, the protective shell 41 can be prevented from being separated from the mounting box 7.

[0031] When the surveying is completed and the drone needs to land, the two groups of support frames 51 are reset. At this time, the two groups of protective shells 41 are not affected by the tension of the connecting rope 42. The elastic force of the reset spring 444 can drive the adjacent slide bar 442 to reset, thereby driving the adjacent protective shell 41 to reset.

[0032] In the present invention, through the cooperation between the supporting mechanism 5 and the protective mechanism 4, when the surveying camera 2 is used, that is, after the drone body 1 takes off, the two groups of supporting frames 51 rotate at the hinges with the mounting frame 6, thereby driving the two groups of protective shells 41 away from each other. When the surveying is completed and the drone needs to land, the two groups of supporting frames 51 are reset, thereby driving the adjacent protective shells 41 to reset.

[0033] The cleaning mechanism 3 includes: a blowing assembly 31 for blowing and cleaning the mapping camera 2, and a wiping assembly 32 for wiping and cleaning the mapping camera 2; the blowing assembly 31 includes: an annular tube 311, through the setting of the annular tube 311, while conveying gas, the mapping camera 2 will not be blocked, and a nozzle 312 connected to the annular tube 311 is provided with a plurality of nozzles 312, which are distributed in an annular array, thereby increasing the cleaning range of the lens surface of the mapping camera 2, improving the cleaning effect, and conveying gas in the annular tube 311. A gas supply unit 313; the gas supply unit 313 includes: a power source 3131 fixedly installed in the installation box 7, a crankshaft 3132 fixedly connected to the output shaft of the power source 3131, a connecting rod 3133 rotatably installed on the crankshaft 3132, a piston 3134 hingedly installed on the other end of the connecting rod 3133, a fixed cylinder 3135 fixedly installed in the installation box 7, and a connecting tube 3136 connecting the fixed cylinder 3135 and the annular tube 311; the piston 3134 is slidably installed in the fixed cylinder 3135.

[0034] When it is necessary to clean the lens of the surveying and mapping camera 2, the power source 1 3131 is started to drive the crankshaft 3132 to rotate, the crankshaft 3132 drives the connecting rod 3133 to move, and the connecting rod 3133 drives the piston 3134 to slide back and forth up and down in the fixed cylinder 3135. Since the piston 3134 slides back and forth up and down in the fixed cylinder 3135, air can be inhaled or discharged into the fixed cylinder 3135. When the air is discharged, the gas is sprayed on the surface of the surveying and mapping camera 2 through the connecting pipe 3136, the annular pipe 311, and the nozzle 312 in sequence, thereby achieving the blowing cleaning of the lens driven by the surveying and mapping camera 2, avoiding dust adhesion on the lens surface, and improving the clarity of the lens shooting.

[0035] Furthermore, since the piston 3134 squeezes the gas in the fixed cylinder 3135 when it moves downward, the pressure in the fixed cylinder 3135 increases, so that the ejected gas has a certain impact force, which can directly act on the dust surface to clean it and improve the cleaning effect.

[0036] In addition, due to the reciprocating movement of the piston 3134, the lens surface of the surveying and mapping camera 2 can be intermittently blown and cleaned, thereby avoiding excessive disturbance or potential damage to the lens surface caused by continuous blowing.

[0037] It should be added here that the power source 3131 is preferably an electric motor.

[0038] As a further extension of the present invention, although the blowing component 31 can clean the dust on the surface of the lens of the surveying and mapping camera 2, since the position and angle of the nozzle 312 are fixed, it is impossible to fully clean the lens, thereby affecting the shooting effect. In the present invention, the wiping component 32 is provided to fully clean the lens, thereby further improving the cleaning effect.

[0039] The wiping assembly 32 includes: a threaded shaft 321 rotatably installed in the installation box 7, the threaded shaft 321 is fixedly connected to the crankshaft 3132, a threaded block 322 threadedly connected to the threaded shaft 321, an adsorbent wiping member 323 fixedly installed on the threaded block 322, a limiting rod 324 for limiting the threaded block 322 during movement, a guide rod 443 passing through the side wall of the threaded block 322, and both ends of the guide rod 443 are fixedly installed in the installation box 7, a guide member 325 for guiding the adsorbent wiping member 323, and a processing unit 326 for cleaning the adsorbent wiping member 323 after use.

[0040] When the power source 3131 is started, the threaded shaft 321 can be driven to rotate. Under the limiting action of the limiting rod 324, the threaded block 322 moves along the axial direction of the threaded shaft 321, thereby driving the adsorption wiping member 323 to move; the adsorption wiping member 323 includes: a connecting rod 3231 fixedly connected to the threaded block 322, a sleeve 3232 sleeved and installed on the connecting rod 3231, a mounting shell 3233 fixedly installed on the sleeve 3232, and an adsorption wiping body 3234 installed in the mounting shell 3233; The length of the adsorption wiping body 3234 arranged in the middle is greater than the diameter of the lens of the surveying and mapping camera 2; when the adsorption wiping member 323 moves along the axial direction of the threaded shaft 321, that is, moves in the horizontal direction, the adsorption wiping member 323 can move along the guide path of the guide member 325 through the setting of the guide member 325, that is, moves in the vertical direction; the guide member 325 includes: a movable rod 3251 fixedly installed on the sleeve 3232, and a guide groove 3252 opened in the installation box 7; the movable rod 3251 slides in the guide groove 3252.

[0041] The guide groove 3252 consists of an initial groove, a transition groove, and a cleaning groove, and the initial groove, the transition groove, and the cleaning groove are connected in sequence.

[0042] Specifically, the threaded block 322 drives the connecting rod 3231 to move axially along the threaded shaft 321, the connecting rod 3231 drives the sleeve 3232 to move axially along the threaded shaft 321, and the sleeve 3232 drives the movable rod 3251 and the mounting shell 3233 to move axially along the threaded shaft 321. Since the movable rod 3251 slides in the guide groove 3252, the movable rod 3251 moves along the axial direction of the threaded shaft 321, and at this time, it moves along the path of the initial groove in a vertical manner, and then moves along the path of the transition groove, and at this time, it can drive the mounting shell 3233 to move downward. This in turn drives the adsorption wiping body 3234 to move downward. When the movable rod 3251 moves to the bottom end of the transition groove, the adsorption wiping body 3234 abuts against the lens surface of the surveying and mapping camera 2. At this time, when the movable rod 3251 moves along the path of the cleaning groove, it can drive the adsorption wiping body 3234 to wipe and clean the lens of the surveying and mapping camera 2. The forward and reverse rotation of the power source 3131 can drive the threaded rod 3263 to rotate forward and reverse, so that the threaded block 322 drives the adsorption wiping member 323 to move back and forth along the path of the cleaning groove, thereby achieving comprehensive cleaning of the lens and further improving the cleaning effect.

[0043] When the lens of the surveying camera 2 is cleaned, the adsorption wiper 323 is reset to the initial position, that is, the movable rod 3251 is reset to the initial groove; at this time, the adsorption wiper 323 is located in the installation box 7, so that dust in the outside air is not easy to adhere to the adsorption wiper 323, avoiding contamination of the adsorption wiper 323, which is conducive to maintaining the cleaning effect of the adsorption wiper 323.

[0044] The absorbent wipe 3234 is preferably a sponge.

[0045] It is added here that an opening matching the adsorption wiping body 3234 is provided on the side wall of the installation box 7, so that the adsorption wiping body 3234 can move from the inside of the installation box 7 to the outside of the installation box 7 when moving along the path of the guide groove 3252.

[0046] The cleaning mechanism 3 also includes: a sac body 33 fixedly installed between the piston 3134 and the fixed cylinder 3135, a liquid storage tank 34 fixedly installed in the installation box 7, the liquid storage tank 34 stores cleaning liquid, a liquid inlet pipe 35 connecting the sac body 33 and the liquid storage pipe, and a liquid outlet pipe 36 connecting the sac body 33 and the installation shell 3233; a one-way valve 1 is installed on the liquid inlet pipe 35, and a one-way valve 2 is installed on the liquid outlet pipe 36.

[0047] During field surveying, dead mosquitoes are easily attached to the lens surface. Although the dead mosquitoes can be cleaned by jetting air from the jet head 312 or reciprocating movement of the adsorption wiping body 3234, mucus is easily left on the lens surface. It is not easy to completely remove the mucus only by jetting air from the jet head 312 or reciprocating movement of the adsorption wiping body 3234, which will affect the clarity of the shooting of the surveying camera 2.

[0048] Specifically, when the piston 3134 moves back and forth, it can synchronously drive the capsule 33 to compress or restore. When the piston 3134 moves downward, it can drive the capsule 33 to compress. At this time, the one-way valve 1 is closed and the one-way valve 2 is opened. The cleaning liquid in the capsule 33 is squeezed out by pressure, and the cleaning liquid enters the mounting shell 3233 through the liquid outlet pipe 36, and is adsorbed by the adsorption wiping body 3234. At the same time, the cleaning liquid can be evenly applied to the lens surface through the reciprocating movement of the adsorption wiping body 3234, so that the mucus reacts with the cleaning liquid, thereby making it easy to completely remove the mucus, thereby greatly improving the clarity of the photography of the surveying and mapping camera 2.

[0049] When the piston 3134 moves upward, it can drive the capsule 33 to recover. At this time, the one-way valve 1 is opened and the one-way valve 2 is closed. At this time, the cleaning liquid in the liquid storage tank 34 can be sucked into the capsule 33, thereby preparing for subsequent work.

[0050] The processing unit 326 includes: a threaded rod 3263 rotatably installed on the installation box 7, a connecting gear 3262 fixedly sleeved on the threaded rod 3263, a rack 3261 meshingly connected to the connecting gear 3262, the rack 3261 is fixedly connected to the adjacent slide bar 442, and the connecting gear 3262 and the rack 3261 are both located in the same installation groove 441, a scraper 3264 threadedly connected to the threaded rod 3263, and a fixed rod 3265 for limiting the position of the scraper 3264 during movement, the fixed rod 3265 passes through the side wall of the scraper 3264, and the fixed rod 3265 is fixedly connected to the inner wall of the installation box 7.

[0051] When the surveying camera 2 is ready to be used, the movement of the support frame 51 can drive the two groups of mounting shells 3233 to move away from each other, the mounting shells 3233 drive the slide bar 442 to move, the slide bar 442 drives the rack 3261 to move, the rack 3261 drives the linkage gear 3262 to rotate, the linkage gear 3262 drives the threaded rod 3263 to rotate, and under the limiting action of the fixed rod 3265, the scraper 3264 moves downward along the axial direction of the threaded rod 3263, so that the adsorption wiping body 3234 can be scraped, so that the stains adsorbed by the adsorption wiping body 3234 when wiping can be scraped off, and the scraped stains are discharged through the opening on the mounting box 7, thereby ensuring the cleanliness of the adsorption wiping body 3234, which is beneficial to maintaining the cleaning effect.

[0052] When the surveying camera 2 is used up, during the landing of the UAV, the power source 2 52 is started to drive the support frame 51 to reset, that is, the support frame 51 is reset to a vertical state. At this time, the two sets of protective shells 41 are reset, thereby driving the rack 3261 to reset, and the rack 3261 drives the linkage gear 3262 to rotate in the opposite direction, thereby driving the scraper 3264 to move upward along the axial direction of the threaded rod 3263, so that the adsorption wiping body 3234 can be scraped again, so that the stains adsorbed by the adsorption wiping body 3234 when wiping can be scraped off, and the scraped stains are discharged through the opening on the mounting box 7, thereby further ensuring the cleanliness of the adsorption wiping body 3234, which is beneficial to maintaining the cleaning effect.

[0053] In the present invention, through the setting of the cleaning mechanism 3, the lens of the surveying and mapping camera can be cleaned multiple times, thereby improving the cleanliness of the lens, thereby ensuring the clarity of the shooting, and the stains adsorbed by the adsorption wiping body when wiping can be scraped off, thereby ensuring the cleanliness of the adsorption wiping body 3234, which is beneficial to maintaining the cleaning effect.

[0054] The present application also includes: a fixing plate 10 fixedly installed on the installation box 7 , an air bag 8 fixedly installed between the fixing plate 10 and the protective shell 41 , and an air guide pipe 9 connecting the air bag 8 and the annular tube 311 .

[0055] When the two groups of protective shells 41 move away from each other, the adjacent airbags 8 can be squeezed, the gas in the airbags 8 is squeezed, and the pressure in the airbags 8 increases. At this time, the gas is sprayed onto the lens surface of the surveying and mapping camera 2 through the air guide tube 9, the annular tube 311, and the nozzle 312 in sequence, so that the lens of the surveying and mapping camera 2 can be pre-cleaned before use to prepare for subsequent use.

[0056] When the two groups of protective shells 41 are reset under the action of the reset springs 444 , the two airbags 8 are restored. Since the airbags 8 themselves have a certain elastic force, they can assist in the reset of the protective shells 41 .
